Referring to FIGS. 4 to 8, a dust scraping structure 3 is provided on the removal movement track of the filter 2 to remove dust adhering on the surface of the filter 2 and prevent dust from being scattered on the edge of the accommodating cavity 11. When using the vacuum cleaner, the filter 2 is located in the accommodating cavity 11. When cleaning the filter 2, open the cover 12 and take the filter 2 out of the accommodating cavity 11. The removal movement track of the filter 2 refers to the removal process The middle filter 2 moves along the accommodating cavity 11. Specifically, the dust scraping mechanism is located on the side wall of the accommodating cavity 11. When the filter 2 is taken out, the dust scraping structure 3 can pre-clean the filter 2 to prevent dust from being scattered on the housing 1, thereby improving user experience.

The dust scraping structure 3 and the filter 2 are in an interference fit. The dust scraping structure 3 is configured to be elastically deformed when the filter 2 is taken out, and can be fully contacted with the filter 2 to improve the pre-cleaning effect and further reduce dust spilling.

The filter 2 includes a frame 21 and a filter 22 connected to the frame 21. The dust scraping structure 3 is an elastic strip, and the elastic strip is in interference fit with the filter 22. When the filter 2 is taken out, the elastic strip will be elastically deformed, which can scrape the filter 22 to achieve pre-cleaning of the filter 22. Here, the filter 22 may be a filter paper or another adsorption layer with adsorption function.

The extension direction of the elastic strip and the motion track of the filter 2 have a set angle, the included angle can be set to 70～100°, such as 80°, 85°, 90°, and the shortest elastic strip is used to ensure filtration When the filter 2 moves, the elastic strip can fully scrape the side of the filter 2.

In this embodiment, the filter 2 is a flat filter, the ash scraping structure 3 is arranged on one side of the filter 2, and the ash scraping structure 3 is interference fit with one side of the filter 2. Of course, if the filter 2 is arc-shaped, the shape of the dust scraping structure 3 matches the shape of the filter 2.

The angle between the extraction movement track of the filter 2 and the horizontal direction is not greater than 90°. In this embodiment, when the vacuum cleaner is placed normally, the opening of the accommodating cavity 111 is upward, and the movement track of the filter 2 is at a certain angle with the horizontal direction, and the angle is an acute angle. Therefore, only the dust scraping structure 3 needs to be provided Just on one side of the filter 2. Specifically, referring to FIG. 5, the filter 2 is inclined to the side where the dust scraping structure 3 is located, which facilitates the dust to fall under the action of its own gravity and facilitates the scraping of the dust scraping mechanism 3.

One end of the filter 2 is provided with a holding portion 23 connected to the frame 21. When the filter 2 is placed in the accommodating cavity 11, the holding portion 23 is located at the opening of the accommodating cavity 11, and the cover 12 and the holding portion 23 abuts to prevent the filter 2 from shifting, and the filter 2 can be easily taken out through the holding and taking part 12 when the cover 12 is opened.

A limit groove 14 is provided inside the accommodating cavity 11, and the end of the filter 2 is provided with a limit protrusion 24 on the frame 21 that can be engaged with the limit groove 14. After the filter 2 is placed in the accommodating cavity 11, the limiting protrusion 24 is locked into the limiting groove 14.

Referring to FIGS. 9 to 12, a limiting portion 13 is provided on the side wall of the accommodating cavity 11, and the filter 2 can abut against the limiting portion 13. Specifically, the limiting portion 13 is a long plate protruding on two opposite side walls of the accommodating cavity 11. When the filter 2 is placed in the accommodating cavity 11, the frame 21 is connected with the holding portion 23 One end of the filter 2 can abut against the limiting portion 13. At this time, the limiting protrusion 24 is locked into the limiting groove 14, indicating that the filter 2 is installed in place.

An initial end and an end corresponding to the removal movement track of the filter 2 are sequentially arranged inward from the opening of the containing cavity 11. The dust scraping structure 3 is located at the initial end and is in interference fit with the end of the side of the filter 2. When the filter 2 is taken out, the dust scraping structure 3 can scrape the filter 22, and the scraping range is from one end of the filter 22 to the other end, so that the dust scraping structure 3 is in full contact with the filter 22 and improves cleaning effect.

In this embodiment, the ash scraping structure 3 is located between the two long strips, so that when the filter 2 abuts the limiting portion 13, the ash scraping structure 3 is just interference fit with one end of the filter 22.

The inner wall of the accommodating cavity 11 is provided with slideways 111 on both sides of the filter 2, and the frame 21 is provided with a protruding part that can be slidably fitted with the slideways 111.

A card slot is provided in the accommodating cavity 11, and the ash scraping structure 3 is clamped with the card slot, which is convenient for installation and disassembly, so as to clean or replace the ash scraping structure 3.

In an embodiment, the dust scraping structure 3 may be a leather strip, and one side of the leather strip is elastically interference fit with the filter 22. When the filter 2 is taken out, the leather strip undergoes a certain degree of elastic deformation in the direction of movement of the filter 2, so that the edge of the leather strip fully abuts the filter 2 and improves the cleaning effect. Here, the leather strip can be made of rubber, real leather or artificial leather, as long as it has a certain degree of elasticity, which is not limited here.

The leather strip includes a clamping part and a cleaning part extending to one side of the clamping part. The cleaning part is elastically interference fit with the filter 22, and the clamping part is connected with the housing 1. The clamping part can be clamped into the card slot. In this embodiment, the clamping part and the cleaning part are vertically connected.

The cross-sectional shape of the cleaning part is wedge-shaped, so that the part of the leather strap in contact with the filter 2 is thin, which facilitates elastic deformation. The wedge-shaped slope faces the inner side of the accommodating cavity 11, so that when the filter 2 is taken out, the leather strap is elastically deformed toward the direction of movement of the filter 2.

In another embodiment, the dust scraping structure 3 can also be a wool top, and the end of the top and the filter 22 are elastically interference fit. When the filter includes a plurality of filter plates 22, part of the tops can be inserted between adjacent filter plates 22. When the filter 2 is taken out, the tops are scraped against the surface of the filter 2, so that the dust on the surface of the filter 2 is sufficiently cleaned, the contact area is increased, and the cleaning effect is improved. The top is installed on the supporting part, and the supporting part is clamped with the slot in the accommodating cavity 11.

After the vacuum cleaner is used to complete the vacuuming operation, open the cover 12, and take out the filter 2 with the hand gripping portion 23. During the movement of the filter 2, the dust scraping structure 3 elastically deforms and comes into contact with the filter 2 in interference. The surface of 2 is scraped to prevent dust on the filter 2 from being carried out and scattered on the housing 1.

Figures 13 to 15 show the second embodiment, in which components that are the same as or corresponding to those in the first embodiment use the reference signs corresponding to the first embodiment. For brevity, only the differences between the second embodiment and the first embodiment are described. The difference is that the angle between the extraction movement track of the filter 2 and the horizontal direction is 0 degrees, that is, the movement track of the filter 2 is set in the horizontal direction.

In this embodiment, when the vacuum cleaner is placed normally, the opening of the accommodating cavity 111 faces the side of the housing 1, and the dust scraping structure 3 is provided at the bottom of the filter 2, and most of the dust on the bottom surface of the filter 2 can be under its own gravity. It falls under the action of the ash, and a part is cleaned under the scraping action of the dust scraping structure 3.
