Example 2

As shown in fig. 6 and 7, the present embodiment is substantially the same as the technical features disclosed in embodiment 1, except that in the present embodiment, a filter screen is disposed at the vent, and a support rib 24 for supporting the filter screen is disposed. Wherein, the filter screen is used for intercepting the dirty that originally is arranged in sweeping the floor robot that comes along with the air current suction, prevents that dirty entering installation cavity 4. Because the wind-force of sweeping the floor robot evacuation station is great, and is less in vent department bore, and the air flow is bigger, in order to guarantee the structural strength of filter screen, sets up brace rod 24 in vent department, and brace rod 24 sets up in the filter screen lower part, supports the filter screen in order to reduce the pressure that the air current caused the filter screen. It should be noted that the filter screen in this embodiment has the greatest effect of preventing the dust collecting device in the dust collecting chamber 3 from being blocked at the vent, for example, the filter screen is blocked by the dust collecting bag, and in practical use, the dirt does not directly contact with the filter screen. Considering manufacturing cost and assembly efficiency problem, can set up the filter screen into detachable construction, be connected filter screen week portion through buckle and vent, more do benefit to the change in daily use.

Example 3

As shown in fig. 5 to 7, the present embodiment is substantially the same as the technical features disclosed in embodiment 1, except that in the present embodiment, a positioning ring rib 22 extending to the upper end 51 of the fan assembly 5 is arranged below the dust collecting cavity 3, and the positioning ring rib 22 is adapted to the size of the upper end 51 of the fan assembly 5. The function of the positioning ring rib 22 is that when the fan assembly 5 is installed below the partition board 2, the upper end part 51 of the fan assembly 5 can quickly enter the positioning ring rib 22 to form installation positioning.

Specifically, the positioning ring rib 22 comprises an outer ring rib 222 and an inner ring rib 221, the fan assembly 5 comprises a housing 54, the housing 54 is of an open structure at the upper end 51 of the fan assembly 5, the fan is arranged in the housing 54, the lifting lug 53 is arranged on the outer periphery of the housing 54, and the housing 54 can be inserted between the outer ring rib 222 and the inner ring rib 221 and is limited by the outer ring rib 222 and the inner ring rib 221. The distance between the outer ring rib 222 and the inner ring rib 221 is used for embedding the housing 54, and the positioning of the upper end part 51 of the fan assembly 5 is ensured through the double structure of the outer ring rib 222 and the inner ring rib 221.

Example 4

As shown in fig. 8, the present embodiment is substantially identical to the technical features disclosed in embodiment 1, except that in the present embodiment, a sealing gasket 57 is disposed between the upper end 51 of the fan assembly 5 and the partition 2. Because the vent is arranged between the upper end part 51 and the partition plate 2, when the air flow in the dust collection cavity 3 enters the fan assembly 5, if the air flow is not reasonably guided, the air flow can generate larger noise when flowing through a gap between the fan assembly 5 and the partition plate 2, the sealing washer 57 is pressed between the fan assembly 5 and the partition plate 2, the air flow can only enter an air inlet of the fan assembly 5 through a middle hole of the sealing washer 57 due to the sealing effect of the sealing washer 57, the effective guiding of the air flow is realized, and the generation of vibration is reduced. Conventionally, the sealing washer 57 is made of a material having a certain elastic deformation to achieve a better sealing effect, for example, the sealing washer 57 may be a rubber sealing washer 57 or a silicone sealing washer 57.

In order to stabilize the air flow, a wind guide ring 23 pressed on the sealing washer 57 is arranged at the vent. The air guide ring 23 is disposed around the vent opening, and the air guide ring 23 guides the air flow to the air inlet of the upper end 51 of the fan assembly 5. There is no gap or hole between the air guiding ring 23 and the partition board 2 and between the air guiding ring and the partition board 2, and the two are of an integrated structure to avoid air leakage and unnecessary noise.

Example 5

As shown in fig. 1, the present embodiment is substantially the same as the technical features disclosed in embodiment 1, except that in the present embodiment, the lower end portion 52 of the fan assembly 5 is provided with a lower end limiting structure 6 abutting against the inner side wall of the installation cavity 4.
