Referring to fig. 6, the drawing direction of the dust collecting drawer 220 is x-y direction, and the included angle formed by the wall surface of the dust inlet 221 is α. The dust inlet 221 of the dust collecting drawer 220 is disposed on the corner cut surface, so that when the dust collecting drawer 220 is covered into the case 210 to abut against the first sealing member 400 on the dust collecting duct 300, part of the forward force is divided under the effect of the angle, so that the first sealing member 400 is more tightly pressed between the dust collecting drawer 220 and the dust collecting duct 300, and the sealing property is enhanced.
Alternatively, in another embodiment, in order to enhance the sealability of the dust box 200, not only the first seal 400 but also the second seal 500 is provided at the blower 700 at the dust collecting duct 300. Specifically, referring to fig. 1 to 4, the dust collecting device 10 mainly includes a main body 100, a parking position of the cleaning robot is disposed at a lower end of the main body 100, and when the cleaning robot is parked at the parking position, the main body 100 has a charging function to directly charge the cleaning robot without additionally providing a charging seat. The main body 100 is further provided with a dust box 200, a blower 700, and a dust collecting duct 300. Regarding the structural arrangement and installation positions of the dust box 200, the blower 700 and the dust collecting duct 300, reference should be made to the limitation of the previous embodiment, and no further description is given here. The first sealing member 400 is disposed between the abutting portion of the dust outlet 310 of the dust collecting pipe 300 and the dust inlet 221 of the dust collecting drawer 220, and the structure and shape of the first sealing member 400 may be various, such as a gasket, a sealing ring, or a special-shaped sealing ring, etc., and the first sealing member 400 is preferably a flared sealing ring (see fig. 7a to 7 c). The sealing member is provided to prevent the gas from leaking during the process of the dust collecting pipe 300 entering the dust box 200, thereby improving the air tightness of the dust box 200. Similarly, the detailed description of the first seal 400 may refer to the limitation of the previous embodiment, and will not be repeated herein.
In this embodiment, the added second seal 500 is disposed between the blower 700 and the dust bin 200. Specifically, the selection blower 700 is installed at one side of the case 210 of the dust box 200, and an air outlet 212 is provided on the case 210, and the air outlet 212 is communicated with the cavity of the dust collecting drawer 220. The fan 700 is installed at the air outlet 212, and the suction port 710 of the fan 700 is in butt joint with the air outlet 212, and the second sealing member 500 is arranged between the suction port 710 and the air outlet 212. The second seal 500 may be sealed in a variety of ways, such as directly between the blower 700 and the housing 210, or around the blower 700 and the dust bin 200. Alternatively, referring to fig. 6, 8a and 8b, the second sealing member 500 has two ends with openings, the first end is sleeved on the periphery of the air outlet 212, and the second end is sleeved on the fan 700 and surrounds the air suction opening 710. For the peripheral edge of the air outlet 212, it can be interpreted that the edge of the air outlet 212 extends out of the outlet wall, and forms a cylindrical structure with a shorter length, which is called the peripheral edge. After the second sealing member 500 seals the periphery of the air outlet 212 of the fan 700 and the box 210, when the fan 700 starts to exhaust air, the air in the dust collection drawer 220 can be completely exhausted through the fan 700, so that the situation that the negative pressure is low due to leakage of the air from the connection part of the fan 700 and the box 210 is effectively avoided.

Specifically, the smaller inner diameter end of the second sealing member 500 is sleeved on the peripheral edge of the air outlet 212, and a certain assembly gap exists between the smaller inner diameter end and the peripheral edge. Similarly, the larger inner diameter end of the second seal 500 fits over the fan 700 with a certain gap therebetween. However, the inner wall of the second sealing member 500 is arranged in a stepped manner, so that the assembly gaps of the two stages are not located on the same annular surface, thereby increasing the flow resistance of gas leakage and effectively reducing the leakage of gas from between the box 210 and the fan 700.
Optionally, referring to fig. 10, the dust collecting device 10 further includes a shock pad 800, and the shock pad 800 is mounted at an end of the blower 700, opposite to the second sealing member 500. It will be appreciated that the shock pad 800 is provided to reduce shock damage to the blower 700 during operation.

The main body 100 is further provided with a dust box 200, a blower 700, and a dust collecting duct 300. Regarding the structural arrangement and installation positions of the dust box 200, the blower 700 and the dust collecting duct 300, reference should be made to the limitation of the previous embodiment, and no further description is given here. The first sealing member 400 is disposed between the abutting portion of the dust outlet 310 of the dust collecting pipe 300 and the dust inlet 221 of the dust collecting drawer 220, and the structure and shape of the first sealing member 400 may be various, such as a gasket, a sealing ring, or a special-shaped sealing ring, etc., and the first sealing member 400 is preferably a flared sealing ring (see fig. 7a to 7 c). The sealing member is provided to prevent the gas from leaking during the process of the dust collecting pipe 300 entering the dust box 200, thereby improving the air tightness of the dust box 200. Similarly, the detailed description of the first seal 400 may refer to the limitation of the previous embodiment, and will not be repeated herein.
The second seal 500 is disposed between the blower 700 and the dust bin 200. Specifically, the selection blower 700 is installed at one side of the case 210 of the dust box 200, and an air outlet 212 is provided on the case 210, and the air outlet 212 is communicated with the cavity of the dust collecting drawer 220. The fan 700 is installed at the air outlet 212, and the suction port 710 of the fan 700 is in butt joint with the air outlet 212, and the second sealing member 500 is arranged between the suction port 710 and the air outlet 212. The second sealing member 500 is arranged at the periphery of the air outlet 212 of the fan 700 and the box 210 in a sealing manner, so that leakage of air from the connection position of the fan 700 and the box 210 is effectively avoided. The second seal 500 is specifically described with reference to the above embodiment, and will not be described herein.
The third seal 600 is described in detail below. Referring to fig. 9, the case 210 of the dust box 200 has an opening 211, and the dust collection drawer 220 may be drawn into the case 210 through the opening 211. The third sealing member 600 is disposed around the edge of the opening 211, the dust collection drawer 220 has a bin cover 222, and when the dust collection drawer 220 is introduced into the case 210, the bin cover 222 covers the opening 211 and seals the opening 211 by the sealing member. It will be appreciated that the provision of the third seal 600 improves the tightness between the dust collection drawer 220 and the housing 210.
Optionally, referring to fig. 9, the third sealing member 600 is an annular sealing ring, and a groove 610 is provided on the outer periphery of the third sealing member 600, where the groove 610 may be snapped with a rim forming the opening 211. By the arrangement of the groove 610, the assembling stability of the third sealing member 600 is further increased, and the sealing performance of the third sealing member 600 is ensured.
The application provides a dust collecting device seals the inlet of dust collection drawer through first sealing member, seals the air outlet of dust collection drawer through the second sealing member, seals between the bin cover of dust collection drawer and the uncovered of box through the third sealing member, and then a plurality of sealing members are simultaneously used in dust collection drawer, make its whole sealed effect show and improve.
The foregoing description is only of the preferred embodiments of the present utility model and is not intended to limit the scope of the utility model, and all equivalent structural changes made by the description of the present utility model and the accompanying drawings or direct/indirect application in other related technical fields are included in the scope of the utility model.
