Detailed ways

Sweeping robots, also known as automatic cleaners, smart vacuum cleaners, robot vacuum cleaners, etc., are a kind of smart household appliances, which can automatically complete the floor cleaning work in the room with certain artificial intelligence. Generally, brushing and vacuuming are used to absorb the debris on the ground into its own garbage storage box, so as to complete the function of ground cleaning. Generally speaking, robots that complete cleaning, vacuuming, and wiping are also classified as sweeping robots.

Just as the role brought by the sweeping robot is huge, the problems it faces are more and more due to its popular use, especially the roller brush used for winding hair, thin lines, etc. Very troubled.

Although there are already cleaning components on the market that can cut off hair, thin lines, etc. for cleaning purposes, such as the patent No. 201920214693.2, which is named as a cleaning component and a cleaning robot, but the cleaning components and cleaning robots used together cannot completely eradicate the entanglement , after long-term use, more entanglements that cannot be removed will accumulate, which is unbearable for most users.

Therefore, in order to make this kind of rolling brush more widely used, as shown in Figure 8 and Figure 10, the present invention provides a winding object cleaning device, at least there is a window 1 corresponding to the rolling brush, and the window 1 is provided with a shaft along the rolling brush shaft. The moving shearing part is formed by splicing a group of parts with teeth 6 on the side edge, wherein the parts are the first part 2 and the second part 3 respectively, the first part 2 and the second part 3 At least one of them does a reciprocating motion to cut off the entanglement;

It should be noted that, according to the above solution, the sweeping robot using this kind of roller brush does not need to deal with the entanglement in a traditional way when removing the entanglement, that is to say, the entanglement can be removed without rotating the cleaning brush;

Therefore, when the sweeping robot moves to the winding cleaning device and the roller brush corresponds to the window 1, the shearing part can move in the axial direction of the roller brush and shear the winding, and the shearing process uses two belt teeth 6 components to achieve (as shown in Figure 5), specifically in a staggered way, such as one side is stationary and the other is active or relatively active at the same time, the two teeth 6 on the combined component realize the cutting of the winding;

E.g:

1. The first component 2 moves and the second component 3 is stationary, and the teeth 6 of the first component 2 are fitted with the teeth 6 of the second component 3 to cut off the wound, which is also an embodiment of the accompanying drawings of this patent;

2. The second part 3 moves and the first part 2 is stationary, and the teeth 6 of the first component 2 fit with the teeth 6 of the second part 3 to cut off the windings. The driving motor 5 is not shown in the drawings of this patent to drive the second part. The illustration of the component 3 can adopt the same structure as that used for driving the first component 2, and other structures can also be used, as long as the above-mentioned functions can be realized.

3. The first part 2 and the second part 3 reciprocate in opposite directions at the same time to form a cutting method, which is also for the purpose of cutting the winding.

As shown in FIG. 10 , in this specific embodiment, the arrangement of the plurality of teeth 6 is perpendicular to the axial direction of the roller brush, and the first part 2 or/and the second part 3 move in an up and down manner To form shearing, the teeth 6 in this operation mode can be closer to the brush bar 20, and the movable space that can be cut is wider, but the arrangement of multiple teeth 6 can be not perpendicular to the axial direction of the roller brush. , as long as the purpose of cutting windings can be achieved.

As shown in Figure 2, the shearing part includes a drive motor 5, and the purpose of the drive motor 5 is to make the rotating member 4 on the motor shaft rotate, and drive the eccentric shaft to rotate, thereby driving the first part 2 or, and the second part 3 to return The activity forms a cutting action;

The above technical solution is to provide a regular trajectory, so that the first part 2 can follow the rotating part to do back-and-forth movement, so as to achieve the purpose of cutting the wound. Of course, the driving mode of this motor is also suitable for the first part. 2. The second part 3 is in the same way of active rotation.

It should be noted that the arrangement direction of the plurality of teeth on the shearing portion can be perpendicular to the axial direction of the roller brush. The surface of the roller brush will not be punctured. Compared with a cleaning assembly and a cleaning robot in the prior art, when dealing with entangled objects, it is no longer necessary to consider the problem of the distance between the cleaning brush and the blade.

In the preferred mode of this specific embodiment, the roller brush includes a plurality of brush bars 20 and cleaning grooves 19 distributed between two adjacent brush bars 20. Since the dust is negatively charged, the hair and the string should be dust. Stick between the two brush strips 20, therefore, on the basis of designing the cleaning groove 19, when the first part 2 penetrates deep into the cleaning groove 19, it can cut off the area adjacent to the cleaning groove 19 and accumulate into a group entanglement, that is to say, limited by the structure of the brush bar 20, the area that the hair and the string can cover to the roller brush belong to the range of activity of the assembly;

Corresponding to the first part 2, an elastic positioning assembly 16 for fixing the first part 2 should also be provided, which is arranged on the movable part 2 in a manner opposite to the teeth 6 on the first part 2. 2 is pressed on the second part 3 by the elastic positioning assembly 16 near the tooth 3 side, therefore, the elastic positioning assembly 16 is provided with at least one end, and this end is fixed with the first part 2;

The above technical solution is adopted because the teeth 6 on the first part 2 are consumables, so it is also necessary to consider the difficulty of replacing the first part 2. For this, the elastic positioning assembly 16 can be moved within a certain space For example, by applying an external force to the elastic positioning member 16, the first part 2 will be turned over.

In this specific embodiment, a component positioning seat 7 is also included. The first component 2 and the second component 3 are mounted on the component positioning seat 7. At the same time, the elastic positioning component 16 is a torsion spring, and the torsion spring has a handle 1601 and a The positioning part 1602, the positioning part 1602 is embedded on the first part 2, and the handle part 1601 is arranged at a position away from the first part 2.

It should be noted that the handle 1601 of the torsion spring is positioned on the assembly positioning seat 7 by means of an axis. Therefore, as can be seen from Figures 3-4, by pressing in the right direction, the torsion spring is turned over with the axis as the center, thereby The first part 2 is driven to separate from the second part 3 .

In the preferred mode of this specific embodiment, as shown in FIG. 2 , the following is an example of how the rotating member 4 drives the first part 2 to move up and down. The rotating member 4 is provided with an eccentric shaft, and the first member 2 is provided with two Blocking parts 8, respectively located above and below the eccentric shaft:

When the eccentric shaft rotates to the top, it contacts the upper blocking part 8 and drives the blocking part 8 and the first part 2 to move upward;

When the eccentric shaft rotates downward, it contacts the blocking part 8 below and drives the blocking part 8 and the first part 2 to move downward, thereby realizing the reciprocating movement of the first part 2 up and down to form shearing.

The range of reciprocating motion of the first component 2 in the up and down direction is determined by the distance between the eccentric shaft and the axis of the rotating member 4 , and the greater the distance, the greater the range of motion.

The reason why the shearing portion can move in the axial direction of the roller brush is that the structure itself is provided with a linear track, and the active area of the linear track supports the shearing portion.

It should be pointed out that the window 1 referred to in this article is arranged on a base station housing 9 with a slope for supporting the cleaning robot. Therefore, as a linear track for implementing the moving function, it is arranged inside the base station housing 9;

As shown in FIG. 6 , the linear track includes a sliding motor 10 , a sliding table 11 , a conveyor belt 12 , a straight shaft 13 , a follower base 15 and a follower 14 mounted on the follower base 15 , the straight shaft 13 The two ends are fixed in the casing, the sliding table 11 is sleeved on the straight shaft 13, and the follower base 15 is fixed on the sliding table 11, and the sliding motor 10 drives the transmission belt to make the sliding table 11 along the straight shaft 13. do back-and-forth exercise;

Further, the connection performance between the conveyor belt 12 and the positioning block 17 can be improved by increasing the contact surface and frictional force. As shown in FIG. There is a positioning block 17 that can be engaged with the conveyor belt 12 , and a belt-shaped body 1701 that abuts against the protruding strips is arranged on the positioning block 17 ; the belt-shaped body 1701 can be triangular.

As shown in FIG. 9, another aspect of the present invention also provides a floor cleaning system, including a base station and a cleaning robot paired with each other, the cleaning robot includes a housing base 18, a driving wheel 21 and a roller brush, and the roller brush and the driving wheel 21 are provided On the housing base 18 of the cleaning robot, the base station housing 9 is provided with the winding object cleaning device according to the present invention;

It should be noted that the surface of the base station housing 9 is provided with two driving wheel grooves 22. When the sweeping robot moves to the base station housing 9 in the direction of the arrow (as shown in FIG. 8), the driving wheel 21 will enter the driving wheel groove 22. so that the roller brush will fall into the window 1, so that the subsequent winding cleaning device can process the winding.

It should also be noted that most of the above explanations are based on the dynamic change of the first part 2 and the static state of the second part 3 for illustration. Other staggered cutting methods of part 2 and second part 3.

The above embodiments are only to describe the preferred embodiments of the present invention, and do not limit the scope of the present invention. On the premise of not departing from the design spirit of the present invention, various modifications and changes made by ordinary engineers and technicians in the art to the technical solutions of the present invention and Improvements should all fall within the protection scope determined by the claims of the present invention.
