In this embodiment, as shown in fig. 4, the support rods include a first support rod and a second support rod. The first supporting rod and the first supporting rod are respectively positioned at the upper end and the lower end of the screw rod.
The driving part can be arranged inside or outside the shell, is connected with a control module of the sweeping robot, and is driven to work or stop by the control module.
In this embodiment, as shown in fig. 2, the driving member is located outside the dust collecting box, and one end of the screw rod penetrates through the side wall of the housing and is connected to the driving member. The driving part is arranged outside the dust collecting box, so that the capacity of the dust storage area in the shell is not reduced.
As shown in fig. 5, the shape of the longitudinal section of the moving plate body is the same as the shape of the longitudinal section of the dust storage area in the housing, and includes an upper end portion, a lower end portion, a front end portion and a rear end portion. Wherein, the upper end part, the lower end part, the front end part and the rear end part are respectively contacted with the inner end surface of the upper cover, the lower end surface and the front end surface in the shell and the filter mesh.
The movable plate body comprises an ash cleaning part and a dust pressing part, the upper end part, the lower end part and the front end part of the movable plate body form the upper end part, the lower end part and the front end part of the dust pressing part, and the rear end part of the movable plate body forms the rear end part of the dust cleaning part.
When the movable plate body moves horizontally in the shell, the rear end part of the ash cleaning part is in contact with the outer wall surface of the filter screen, so that dust attached to the filter screen can be cleaned.
In addition, when the moving plate body moves horizontally in the housing, the dust pressing part may push dust particles in the dust storage region in the housing from one end region to the other end region of the dust storage region to compress the dust particles in a loose state, thereby increasing a dust storage space in the dust storage region to store more dust particles.
In addition, the movable plate body also comprises a support rod through hole, a screw rod through hole and a gas through hole. When the dust pressing part compresses the dust particles in a loose state, gas in the dust particles can be guided to the other end region of the dust storage region through the gas through holes, and the dust particles are also favorably compressed by releasing the gas in the dust particles in the loose state.
As shown in fig. 3, when the dust particles are pushed to one end of the dust storage area by the dust pressing portion, a new dust storage space is formed between one side wall surface of the dust pressing portion and the inner wall surface of the housing close to the dust pressing portion. The dust storage space is positioned on one side of the filter mesh and cannot be contacted with the filter mesh, so that the filtering effect cannot be influenced after dust-containing fluid enters the dust collection box through the fluid inlet.
The ash removing part and the dust pressing part can be made of the same material or different materials. When the two are made of different materials, the dust removing part can be made of soft materials (such as soft rubber materials) to form a soft scraping strip structure, and the dust pressing part can be made of hard materials (such as metal materials).
In this embodiment, the driving member is located outside the dust collecting box, and one end of the screw rod penetrates through the side wall of the housing and is connected with the driving member.
The invention has the beneficial effects that:
1. the cleaning assembly can clean dust attached to the filter mesh and compress loose dust particles in the dust storage area, so that the dust storage space in the dust storage area is increased to store more dust particles, and the frequency of cleaning dust in the dust collection box can be reduced;
2. a gap is formed between the filter net sheet and the filter handkerchief through the front frame part, so that the circulation of fluid is facilitated, and the filtering effect of the filtering component is ensured;
3. after the filter net is additionally arranged on the front side of the filter sea handkerchief, two-stage filtering effect can be realized, and large-particle dust and dirt such as hair can be prevented from being attached to the surface of the filter sea handkerchief to influence the filtering effect of the filter sea handkerchief.
