Description

A dust box self-cleaning vacuum cleaner

technical field

The utility model relates to the technical field of cleaning equipment, in particular to a dust box self-cleaning vacuum cleaner.

Background technique

The dust box of existing vacuum cleaners is usually fitted with a filter device which is arranged to filter out fine dirt and dust particles from the air flow through the cleaner, which results in the amount of fine dirt and dust collected by the filter device increasing with the size of the filter. Increased use time will eventually cause the filter holes to become clogged, requiring cleaning or replacement of the filter to maintain efficient airflow through the vacuum. However, the clogging of the filter device is easily overlooked, which leads to a decrease in the filtering efficiency of the filter device, which further affects the air suction efficiency of the vacuum cleaner; in addition, the cleaning and/or replacement of the filter device is an easy cause for the user to directly contact the dirt. process of things.

Detailed ways

The technical solutions in the embodiments of the present utility model will be clearly and completely described below with reference to the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the implementations. example. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the protection scope of the present invention.

Referring to FIGS. 1 to 6 , the present application exemplifies a vacuum cleaner, comprising a housing 10 , a fan 30 for sucking air from a work surface is installed on the housing 10 , and a dust duct is arranged on the air duct along which the fan 30 sucks air and flows. A filter device 201 is detachably installed on the dust box 20. When the vacuum cleaner passes through the work surface, the fan 30 will suck the air containing dust from the work surface, and the air enters the dust box 20 and is filtered by the filter device 201 to remove the dust. The dust remains in the dust box 20, and the filtered air is discharged along the air duct.

A beating device 202 is provided at a position corresponding to the filter device 201. The beating device 202 includes a driving part 2020 and a beating part 2021. The driving part is fixed on the dust box 20; The other end of the 2021 is linked with the driving part 2020, and the driving part 2020 drives the beating part 2021 to periodically beat the filter device 201, so that the filter device 201 vibrates and the dust blocked on the filter device 201 is shaken, so as to solve the problem of dust blocking the filter Problem with device 201. Of course, depending on the structure of the cleaner, the driving part 2020 can also be arranged on the housing 10 to drive the flapping part 2021 to beat the filter device 201 .

Example 1

As shown in FIG. 2, the dust box 20 has an upper box cover 20A and a lower box cover 20B. The upper box cover 20A and the lower box cover 20B are combined to form a garbage dust collecting chamber of the dust box 20, and a filter device 201 is arranged in the garbage dust collecting chamber. The cavity is divided, the air containing dust is filtered and retained in the dust box 20 by the existence of the filter device 201 , and the air is discharged out of the dust box 20 through the filter holes of the filter device 201 .

As shown in FIG. 3 , the beating device 202 includes a driving motor 2020 and a beating part 2021 , the driving motor 2020 is installed on the dust box 20 , and the beating part 2021 is installed on the output shaft of the driving motor 2020 to rotate with the rotation of the output shaft of the driving motor 2020 , as shown in the figure, the flapping part 2021 has at least one protruding part, and the protruding part contacts the filtering device 201 during the rotation. The beating part 2021 hits the filter device 201 during the rotation process, and by periodically hitting the filter device 201 continuously or intermittently, the filter device 201 is vibrated, so that the blockages attached to the filter holes of the filter device 201 also follow. Vibrate, and disengage from the filter hole during the vibration process, so that the filter hole is unblocked.

The protruding part of the flapping part 2021 may be a rubber body, because the rubber body can avoid or reduce the damage of the flapping part to the filter device 201, and can also reduce the noise generated during flapping.

Embodiment 2

As shown in FIGS. 4 to 6 , the flapping device 202A includes a driving part 2020A and a flapping part 2021A, and the driving part 2020A is mounted on the dust box 20 . The flapping part 2021A is in the shape of a rod, and the rod is rotatably fixed on the dust box 20 or the housing 10 of the vacuum cleaner through a connecting piece 203 , and one end of the rod is linked with the driving part 2020A, and the other end of the rod faces the filter device 201 . When the driving part 2020A drives one end of the rod to move, the other end of the rod moves relative to the filter device 201 and hits the filter device 201 during the movement, causing the filter device 201 to vibrate. It can be known that the flapping portion 2021A forms a lever through the connecting member 203 , one end of the lever is linked with the driving portion 2020A, and the other end of the lever moves relatively with the filtering device 201 . Since the filter device 201 will be placed horizontally, setting the beating device 202A in the vertical direction to hit the filter device 201 will cause the height of the vacuum cleaner to increase. Therefore, when the lever principle is used, the self-repeating position of the rod end cannot be used to achieve sustainable hitting action.

As shown in FIG. 5 , a spring or rubber elastic member 204 is arranged between the rod and the dust box 20 or the housing 10 , and the elastic member 204 provides a linkage end between the rod striking end 2021A0 and the other driving part 2020A. The opposite force can approach and hit the filter device after being affected by the linkage end and away from the filter device 201 .

As shown in FIG. 6 , the hitting end 2021A0 of the rod will be away from the filtering device 201 after hitting the filtering device 201 under the influence of the linkage end.

In the above-mentioned second embodiment, the driving part 2020A includes a motor and a cam 2020A0. The cam 2020A0 is installed on the output shaft of the motor and is linked with one end of the rod. The rotation of the cam 2020A0 is constantly in contact with one end of the rod, so that the hitting end 2021A0 of the rod is in constant contact with one end of the rod. Constantly lifting or falling, hitting the filter device 201 when falling.

The above disclosures are only the preferred embodiments of the present invention, and of course, the scope of the rights of the present invention cannot be limited by this. Therefore, the equivalent changes made according to the claims of the present invention still belong to the scope covered by the present invention.
