Detailed Description

The following description of the embodiments of the present application will be made clearly and fully with reference to the accompanying drawings, in which it is evident that the embodiments described are some, but not all embodiments of the application. All other embodiments, which can be made by those skilled in the art based on the embodiments of the application without making any inventive effort, are intended to be within the scope of the application.

The following describes embodiments of the present application in detail through specific embodiments and application scenarios thereof with reference to the accompanying drawings.

Referring to fig. 1-12, in some embodiments, a floor scrubber is provided, comprising: handle assembly 100, retaining member 400, fresh water tank 200, roller brush assembly 500, pump assembly 600, and support bracket 700. Wherein the handle assembly 100 is usable for being held by a user to facilitate the user's operation of the floor scrubber; the roller brush assembly 500 may be used to contact a floor to be cleaned, such as a flat ground or stairs, and clean the floor to be cleaned to remove impurities or dirt on the floor; the clean water tank 200 may be used to store clean water, and the pump assembly 600 may be used to supply water in the clean water tank 200 to the brushes in the brush roller assembly 500, and the wetted brushes are rotated by the driving motor to clean the ground; the locking member 400 may be used to lock the handle assembly 100 and the rolling brush assembly 500 to prevent the handle assembly 100 and the rolling brush assembly 500 from moving relative to each other, and the locking member 400 may also unlock the handle assembly 100 and the rolling brush assembly 500 to allow the handle assembly 100 to move relative to the rolling brush assembly 500; alternatively, the locking member 400 may be further used to drive the supporting frame 700 to move, so that the supporting frame 700 protrudes from the rolling brush assembly 500; the support stand 700 may be used to provide support to ensure that the floor scrubber is generally stable and does not topple over.

In this embodiment, the clean water tank 200 is disposed on the handle assembly 100, for example, the clean water tank 200 is disposed on the middle upper end of the handle assembly 100; this is convenient for the user to operate, is easy for the overall machine to be arranged, is compact, and can be arranged at other positions of the handle assembly 100, and is not particularly limited.

In this embodiment, in order to enable the handle assembly 100 to move relative to the rolling brush assembly 500, one end of the handle assembly 100 is movably connected to the rolling brush assembly 500 at a lower end, so that the handle assembly 100 can be moved relative to the rolling brush assembly 500 to adjust the orientation of the handle assembly 100, which is convenient for a user to operate the machine. The support frame 700 is disposed at an upper end or a top end of the rolling brush assembly 500, and can move up and down along a direction perpendicular to the ground with respect to the rolling brush assembly 500, so that the support frame plays a role of supporting, for example, the support frame 700 can have a first position and a second position; for example, when the support frame 700 is in the second position, a part of the support frame 700 is retracted relative to the rolling brush assembly 500, such as the bottom end of the support frame 700 is separated from the ground, so that the rolling brush of the rolling brush assembly 500 can contact with the ground to be cleaned; or when the support frame 700 is located at the first position, a part of the support frame 700 can protrude from the rolling brush assembly 500 to be supported on the bearing surface, for example, the bottom end of the support frame 700 is contacted with the ground, so that the machine can stand stably. In this embodiment, the supporting points are arranged on the outer sides of the double rolling brushes of the floor washing machine by using the supporting frame 700 capable of moving up and down, so that the distance between the supporting points is increased, the supporting arm is longer, meanwhile, the supporting points and the ground are hard supports, and the supporting stability is better compared with the soft supports of the surface of the rolling brushes and the ground.

The locking member 400 is slidably connected to the handle assembly 100 and is in contact with the support frame 700; the locking member 400 has a first locking portion 410, and accordingly, the rolling brush assembly 500 has a second locking portion 571, and the second locking portion 571 can be locked with or disengaged from the first locking portion 410. In this embodiment, in order to switch the state of the locking member 400, the locking member 400 is slidably connected to the handle assembly 100, so that the locking member 400 can slide relative to the handle assembly 100, and thus can slide to lock with the rolling brush assembly 500 or slide to unlock from the connecting assembly, so as to switch between the locked state and the unlocked state. Further, to switch the position of the support bracket 700, the locking member 400 is slidably coupled to the handle assembly 100 and is in contact with the support bracket 700, e.g., the locking member 400 may be moved up and down along the handle assembly 100.

Based on this, in the case that the locking member 400 is located at the first position with respect to the handle assembly 100, for example, when the locking member 400 is located at the bottom end of the handle assembly 100, the locking member 400 drives the support frame 700 to move toward the extending direction away from the handle assembly 100, that is, toward the ground, so that at least part of the support frame 700 protrudes out of the roller brush assembly 500, wherein the extending direction of the handle assembly 100 may be, for example, upward; with the retaining member 400 in the second position relative to the handle assembly 100, such as when the retaining member 400 is disengaged from the bottom end of the handle assembly 100 and is positioned at a lower or middle portion of the handle assembly 100, the support 700 is moved toward the extension of the handle assembly 100 such that at least a portion of the support 700 is retracted into the roller brush assembly 500. For example, when the locking member 400 approaches the supporting frame 700, it contacts the supporting frame 700 and drives the supporting frame 700 to move relative to the rolling brush assembly 500, so that part of the supporting frame 700 protrudes out of the rolling brush assembly 500 to play a supporting role; when the locking member 400 is disengaged from the supporting frame 700, the supporting frame 700 is reversely moved with respect to the rolling brush assembly 500, so that a portion of the supporting frame 700 is retracted with respect to the rolling brush assembly 500, thereby facilitating the cleaning operation by the rolling brush assembly 500.

The roller brush assembly 500 includes a first roller brush 510 and a second roller brush 520 arranged at intervals, the pump assembly 600 is in communication with the fresh water tank 200, and the pump assembly 600 may be disposed between the first roller brush 510 and the second roller brush 520 for supplying water in the fresh water tank 200 to the first roller brush 510 and the second roller brush 520, respectively. In this embodiment, the rolling brush assembly 500 adopts a structure of double rolling brushes, so as to effectively improve the cleaning effect and the cleaning efficiency. By the arrangement of the pump assembly 600, it is possible to selectively supply water in the fresh water tank 200 to both the first and second rolling brushes 510 and 520, or to supply water in the fresh water tank 200 to only one of the first and second rolling brushes 510 and 520, or to stop the supply of water to the first and second rolling brushes 510 and 520.

Therefore, based on the arrangement, the floor scrubber can have various states or modes, such as a first working state for cleaning long and narrow surfaces to be cleaned, such as steps, stairs and the like, which need to be cleaned back and forth, a second working state for cleaning flat ground, and a non-working state for storage. In one aspect, when the floor scrubber is in the first working state, the locking member 400 is located at the second position relative to the handle assembly 100, the first locking portion 410 is disengaged from the second locking portion 571, so that the handle assembly 100 can rotate relative to the rolling brush assembly 500, the supporting frame 700 moves towards the extending direction of the handle assembly 100, so that at least part of the supporting frame 700 is retracted into the rolling brush assembly 500, and the pump assembly 600 sprays water in the clean water tank 200 onto the first rolling brush 510 and the second rolling brush 520 simultaneously. In this working state, the cleaning operation of the stairs can be performed, and when the stairs are cleaned, the two-way back and forth movement is required, so that water is simultaneously supplied to the double rolling brushes, namely the first rolling brush 510 and the second rolling brush 520, and the stairs are cleaned by the double rolling brushes, so that the cleaning effect is ensured; meanwhile, to avoid interference of the supporting frame 700, at least part of the supporting frame 700 is retracted into the rolling brush assembly 500, and by retracting the supporting frame 700 without interfering with the rolling brush assembly 500 contacting the floor, a cleaning operation can be performed by using the double rolling brushes in the rolling brush assembly 500 contacting the floor.

On the other hand, in the case that the floor scrubber is in the second operating state, the locker 400 is located at the second position with respect to the handle assembly 100, the first locking part 410 is disengaged from the second locking part 571 so that the handle assembly 100 can be rotated with respect to the rolling brush assembly 500, the supporting frame 700 is moved toward the extending direction of the handle assembly 100 so that at least a portion of the supporting frame 700 is retracted into the rolling brush assembly 500, the pump assembly 600 sprays water in the fresh water tank 200 onto one of the first rolling brush 510 or the second rolling brush 520, for example, the pump assembly 600 may supply water in the fresh water tank 200 only onto the first rolling brush 510 without supplying water to the second rolling brush 520, or the pump assembly 600 may supply water in the fresh water tank 200 only onto the second rolling brush 520 without supplying water to the first rolling brush 510. In the working state, the cleaning operation of the flat ground can be performed, and when the flat ground is cleaned, water can be supplied to only one of the double rolling brushes, so that the cruising of water and electricity can be improved, resources are saved, and the cost is further saved; in addition, for convenience of user operation, when cleaning the flat ground, the handle assembly 100 can be rotated relative to the roller brush assembly 500 by making the locking member 400 in the unlocked state, so that the user can clean the ground in the rotated state of the handle assembly 100; meanwhile, to avoid interference of the supporting frame 700, at least part of the supporting frame 700 is retracted into the rolling brush assembly 500, and by retracting the supporting frame 700 without interfering with the rolling brush assembly 500 contacting the floor, a cleaning operation can be performed by using the double rolling brushes in the rolling brush assembly 500 contacting the floor.

In still another aspect, when the floor scrubber is in the non-operating state, the locking member 400 is located at the first position relative to the handle assembly 100, the first locking portion 410 and the second locking portion 571 cooperate to lock the rolling brush assembly and the handle assembly 100, and keep the handle assembly 100 upright, and the locking member 400 drives the support frame 700 to move in a direction away from the extending direction of the handle assembly 100, i.e. in a direction approaching the ground, so that at least part of the support frame 700 protrudes beyond the rolling brush assembly 500, and the pump assembly 600 stops supplying water to the first rolling brush 510 and the second rolling brush 520. At this time, the machine can be stored, for example, when the floor washing machine is not used, the support frame 700 plays a supporting role to ensure that the floor washing machine stably stands without tilting and toppling, so that the floor washing machine can be stably placed; meanwhile, under the condition, the handle assembly 100 can be kept upright by enabling the locking piece 400 to be in the locking state, the handle assembly 100 can be kept not to topple over relative to the rolling brush assembly 500, so that the floor washing machine can be kept standing and not topple over in the non-working state conveniently, in-situ storage of the floor washing machine can be realized without other auxiliary equipment, leaning on a wall surface or the like, the operation is convenient, the structure is simple, the cost is low, and the use experience of a user is improved.

Therefore, the floor scrubber of the embodiment can be used for cleaning the floor and also can be used for cleaning stairs, and can be conveniently stored in a non-working state, for example, the floor can be supported by the bottom supporting point of the supporting frame 700, and meanwhile, the handle assembly 100 is kept in an upright state, so that the floor scrubber can be stably stood without tilting or toppling, and the floor scrubber can be stably placed and stored in situ. Therefore, the problems that the current floor washing machine is unstable and easy to incline or overturn and the switching between the non-working state and the working state is inconvenient when being placed can be solved, and the problem that the floor washing machine can only clean on a plane and cannot clean stairs can be solved.

In some embodiments, the floor washing machine further includes a sump 300, the sump 300 being provided to the handle assembly 100. In this embodiment, in order to recover or store the sewage generated by the rolling brush in the rolling brush assembly 500, a sewage tank 300 is further provided, and both the sewage tank 300 and the clean water tank 200 may be provided on the handle assembly 100, for example, the sewage tank 300 is provided below the clean water tank 200, so that the structure is compact, the layout is reasonable, and the operation of the user is facilitated.

It should be noted that, in this embodiment, the clean water tank 200 and the sewage tank 300 are provided to the handle assembly 100, and the specific structure, connection arrangement, etc. of the clean water tank 200 and the sewage tank 300 can be referred to in the prior art, and this embodiment is not limited thereto, and will not be described in detail herein.

In some embodiments, the pump assembly 600 includes a fresh water pump 610, a water pipe connected to the fresh water pump 610, the fresh water pump 610 may be in communication with the fresh water tank 200 and the roller brushes in the roller brush assembly 500 through the water pipe, and fresh water in the fresh water tank 200 may be supplied to the first roller brush 510 and the second roller brush 520 through the fresh water pump 610 in the pump assembly 600.

Under the elastic force of the elastic return piece 800, the supporting frame 700 can be in a retracted state, and at the moment, the rolling brush of the rolling brush assembly 500 can be contacted with the ground to realize cleaning operation; when the floor washer needs to be placed or stored, the supporting frame 700 can be extruded, so that the elastic return piece 800 stores elastic potential energy, and the supporting frame 700 protrudes relative to the rolling brush assembly 500, so that a supporting effect is achieved through the supporting frame 700, and stable standing of the floor washer can be achieved. It should be noted that, in a state where the elastic return member 800 stores elastic potential energy, the supporting frame 700 may be locked by the locking member 400 or other members, so as to prevent the supporting frame 700 from being retracted by the elastic force of the elastic return member 800.

Optionally, the elastic return element 800 includes a compression spring, and the compression spring may push the support 700 to retract the support 700.

In order to prevent the compression spring from moving randomly, at least one of the rolling brush assembly 500 and the support frame 700 is provided with a limiting groove, and the end of the compression spring is arranged in the limiting groove so as to play a limiting role on the end of the compression spring through the limiting groove, thereby preventing the end of the compression spring from moving randomly. Of course, the limit groove can be provided with one or more limit grooves, and the specific number, namely the arrangement form, can be selected according to the actual working condition.

Specifically, the top surface of the connection frame 570 of the rolling brush assembly 500 may be provided with a first limit groove 573, and the inner surface of the connection plate 730 of the support frame 700 may be provided with a second limit groove 732, and the first limit groove 573 and the second limit groove 732 are oppositely disposed, and two ends of the compression spring are respectively located in the first limit groove 573 and the second limit groove 732, so that two ends of the compression spring can be respectively limited through the first limit groove 573 and the second limit groove 732, so that two ends of the compression spring can be prevented from moving at will, and the rolling brush assembly further has a certain guiding effect on the compression spring, so as to alleviate the problem of distortion and deformation of the compression spring.

In this embodiment of the present application, the locking member 400 and the supporting frame 700 may be contacted or separated, specifically, when the locking member 400 is located at the lower end of the handle assembly 100, the locking member 400 is abutted against the connection plate 730 of the supporting frame 700, and at this time, the compression spring is in the first compression state, so that the supporting frame 700 is prevented from retracting under the action of the elastic force of the compression spring by the locking member 400, and in this state, the supporting function may be achieved through the supporting frame 700, so as to facilitate the stable placement of the floor washing machine.

In the case that the locking member 400 moves upward along the handle assembly 100, the locking member 400 is separated from the connection plate 730, and the compression spring is in the second compressed state, and the compression degree of the second compressed state is smaller than that of the first compressed state, or the compression spring is in the original length state. Specifically, when the locking member 400 is in the second position, it releases the pressing action on the connection plate 730, and at this time, the supporting frame 700 can be retracted under the action of the elastic force of the compression spring, so that the rolling brush of the rolling brush assembly 500 can contact with the ground for normal cleaning operation. It should be noted that, when the locking member 400 is separated from the connecting plate 730, the compression spring stretches, and when the supporting frame 700 is not limited at all, the compression spring can recover to the original length; of course, in order to avoid the support 700 from being separated from the rolling brush assembly 500 without being limited, a limiting structure is disposed between the support 700 and the rolling brush assembly 500, and when the support 700 is retracted for a certain distance, the support 700 is limited by the limiting structure and is not retracted any more, at this time, the compression spring may still be in a compressed state, but the compression degree of this state is less than that of the locking member 400 when it is stopped against the connecting plate 730 of the support 700. Thus, when the support 700 is in the retracted state, the compression spring may be in the second compressed state or the original length state.

In some embodiments, the second locking portion 571 may be in locking engagement with or disengaged from the first locking portion 410. For example, in the case that the locking member 400 is located at the first position with respect to the handle assembly 100, the first locking portion 410 cooperates with the second locking portion 571 to lock the rolling brush assembly 500 and the handle assembly 100, so that the handle assembly 100, the locking member 400 and the rolling brush assembly 500 cannot move relatively, in which case the handle assembly 100 can be kept from tilting with respect to the rolling brush assembly 500, and the handle assembly 100 can be kept standing without tilting. With the locking member 400 in the second position relative to the handle assembly 100, the first locking portion 410 is disengaged from the second locking portion 571 such that the roller brush assembly 500 is rotatable relative to the handle assembly 100, thereby allowing the angle of the handle assembly 100 relative to the roller brush assembly 500 to be adjusted for convenient operation of the floor scrubber by a user.

In the embodiment of the present application, the handle assembly 100 can rotate relative to the rolling brush assembly 500, so as to be convenient for a user to use; when the user does not use the floor scrubber, the locking member 400 is slid to lock the first locking portion 410 and the second locking portion 571 with each other, so that the locking member 400 is prevented from moving relative to the rolling brush assembly 500, and the handle assembly 100 is locked with the rolling brush assembly 500 along with the locking member 400 due to the fact that the locking member 400 is connected to the handle assembly 100, so that the handle assembly 100 cannot rotate relative to the rolling brush, and at this time, it is ensured that the floor scrubber cannot topple over the handle assembly 100 in a standing condition, and the handle assembly 100 is kept in an upright state.

Optionally, one of the first locking portion 410 and the second locking portion 571 is a protruding structure, the other is a groove structure, and the protruding structure is matched with the groove structure. When the locking member 400 slides to the first position, the protruding structure is located in the groove structure, so that the locking member 400 and the rolling brush assembly 500 can be limited to move relatively through cooperation of the protruding structure and the groove structure, and the locking member 400 is arranged on the handle assembly 100, so that the handle assembly 100 cannot rotate relative to the rolling brush assembly 500 along with the locking member 400, and further locking between the handle assembly 100 and the rolling brush assembly 500 is achieved, so that the handle assembly 100 is prevented from tilting due to rotation, and the handle assembly 100 is kept in an upright state.

Wherein, the first locking portion 410 may be a protrusion structure, and the second locking portion 571 is a groove structure; of course, the first locking portion 410 may have a groove structure, and the second locking portion 571 may have a protrusion structure. The specific mode can be selected according to the actual working condition.

Alternatively, the outer wall of the locker 400 is provided with an elongated groove structure extending in the sliding direction of the locker 400, and accordingly, the top of the connection frame 570 in the roll brush assembly 500 is provided with an elongated protrusion structure extending in the sliding direction of the locker 400. Therefore, in the sliding process of the locking member 400 to the first position, the elongated protrusion structure gradually slides into the elongated groove structure, and when the elongated protrusion structure completely slides into the elongated groove structure, the locking of the handle assembly 100 and the rolling brush assembly 500 can be realized, so that the angle cannot be adjusted. When the locking is required to be released, the locking piece 400 is reversely slid to the second position, so that the long-strip-shaped protruding structure gradually slides out of the long-strip-shaped groove structure, and when the long-strip-shaped protruding structure completely slides out of the long-strip-shaped groove structure, the unlocking state of the handle assembly 100 and the rolling brush assembly 500 can be realized, so that the handle assembly 100 can swing to adjust the angle.

To improve stability and reliability of the locked state to prevent the release, the locking member 400 may have a plurality of first locking portions 410, and accordingly, the rolling brush assembly 500 may have a plurality of second locking portions 571, so that the plurality of first locking portions 410 are engaged with the plurality of second locking portions 571 in a one-to-one correspondence manner in a case that the locking member 400 is located at the first position with respect to the handle assembly 100. With this arrangement, the plurality of first locking portions 410 and the plurality of second locking portions 571 are respectively engaged to achieve multi-point locking, so that locking force can be improved, and it is ensured that the handle assembly 100 does not rotate relative to the rolling brush assembly 500 in the locked state.

In some embodiments, the locking member 400 is a sleeve member that slidably fits over the outside of the handle assembly 100. Mounting of retaining member 400 may be accomplished by handle assembly 100 on the one hand, and sliding of retaining member 400 relative to handle assembly 100 may be facilitated to facilitate switching of the position of retaining member 400 between the first and second positions on the other hand.

In the embodiment of the present application, the handle assembly 100 includes a handle bar 110 and a connector 120, wherein one end of the handle bar 110 is rotatably connected to the connector 120 through a first connecting shaft, the connecting shaft is rotatably connected to the rolling brush assembly 500 through a second connecting shaft, and the axis of the first connecting shaft is perpendicular to the axis of the second connecting shaft. Based on this, the connection head 120 may rotate with respect to the handle bar 110 about the first connection shaft, and the rolling brush assembly 500 may rotate with respect to the connection head 120 about the second connection shaft, and the rotation direction of the rolling brush assembly 500 is perpendicular to the rotation direction of the connection head 120, so that the rolling brush assembly 500 (or the handle bar 110) may be rotated in multiple directions to adjust the angle between the rolling brush assembly 500 and the handle assembly 100, so that the rolling brush assembly 500 may be in contact with the ground all the time, and the user may optionally rotate the orientation of the handle assembly 100, so as to operate the floor scrubber.

To prevent the release, the locking member 400 has a first stop 420, and correspondingly, the handle assembly 100 has a second stop 111, such that the first stop 420 is in stop engagement with the second stop 111 with the locking member 400 in the first position relative to the handle assembly 100. Through the cooperation of the first spacing portion 420 and the second spacing portion 111, the movement of the locking member 400 relative to the rolling brush assembly 500 can be restricted, so that the situation that the first locking portion 410 and the second locking portion 571 are separated from each other to release can be effectively avoided, and the stability and reliability of the locking state are further ensured. Meanwhile, through the cooperation of the first limiting part 420 and the second limiting part 111, the locking piece 400 can be stopped against the supporting frame 700, and the supporting frame 700 is prevented from retracting under the elastic force of the elastic return piece 800, so that the floor washing machine can stably stand without tilting or toppling.

Optionally, one of the first limiting portion 420 and the second limiting portion 111 is a convex structure, the other is a concave structure, and the convex structure is adapted to the concave structure. Thus, the male structure can move into the female structure to realize the clamping fit, so that the locking member 400 can be prevented from moving relative to the rolling brush assembly 500 to release.

In a specific embodiment, the handle assembly 100 has an elastic connection piece 112, and the male structure is connected to the elastic connection piece 112, so that when the male structure is subjected to a pressing force, the male structure can be moved by elastic deformation of the elastic connection piece 112, so as to facilitate the male structure to enter the female structure.

Specifically, one end of the elastic connection piece 112 may be connected to the outer wall of the handle bar 110, and the male structure is connected to the other end of the elastic connection piece 112, so that the male structure may be moved.

In addition, the handle assembly 100 may have a plurality of elastic connection pieces 112, each elastic connection piece 112 is connected with a convex structure, and each convex structure corresponds to a corresponding concave structure, so that the locking stability can be improved by matching the convex structures with the concave structures, so as to prevent the locking member 400 from being accidentally separated from the rolling brush assembly 500 to cause accidental release.

In some embodiments, the handle assembly 100 further has a third limiting portion 113, the third limiting portion 113 is located on a side of the second limiting portion 111 away from the roller brush assembly 500, and the first limiting portion 420 is engaged with the third limiting portion 113 when the locking member 400 is located at the second position relative to the handle assembly 100. In this way, the locking member 400 can be stationary relative to the handle assembly 100 under the condition of unlocking the locking state, so that the situation that the handle assembly 100 cannot rotate relative to the rolling brush assembly 500 due to the fact that the locking member 400 moves to the first position in the process of operating the floor washing machine by a user can be avoided, and normal use of the floor washing machine can be ensured.

In summary, in the floor scrubber according to the embodiment, when the floor scrubber is not in use, that is, when the floor scrubber is in a non-working state, the locking member slides to the first position, the supporting frame plays a supporting role, and meanwhile, the handle assembly keeps a vertical locking state, so that the floor scrubber is ensured to stably stand without tilting or toppling, and thus, the floor scrubber can be stably placed and stored in situ. When the floor washing machine is required to be used, the locking piece slides to the second position, the support frame is retracted without interfering with the contact of the rolling brush in the rolling brush assembly with the ground, and meanwhile, the handle assembly is rotatable relative to the support frame and the rolling brush assembly, so that the machine is converted from a non-working state to a working state, and normal cleaning operation can be realized. The floor washing machine can have various working states, such as a first working state with long and narrow surfaces to be cleaned, such as steps, stairs and the like, which need to be cleaned in a reciprocating manner, a second working state with flat surfaces to be cleaned and the like, and the problem that the conventional floor washing machine can only clean on a plane and cannot clean stairs can be solved.
