In an embodiment, the fan assembly 130 includes a fan 131 and a sealing member 133 located at an outlet of the fan channel 117, the sealing member 133 seals a gap between the fan 131 and the outlet of the fan channel 117 to facilitate the fan 131 to draw air away under a sealed condition, when the fan 131 is powered on, the fan 131 can draw air out of the accommodating cavity 111 through the fan channel 117, at this time, the accommodating cavity 111 forms wind pressure with the outside, and air located outside can suck the garbage located in the dust suction channel 113 into the accommodating cavity 111.

Referring to fig. 1 and 2, in an embodiment, when the dust collecting case 110 having the receiving cavity 111 needs to be taken out of the opening and closing device 200 to dump the garbage, since the dust collecting device 100 is mounted to the body 210, this can be achieved by opening the cover 220. Referring to fig. 7 and 8, when the cover 220 needs to be opened, a user needs to push one hand against the cover 220 and push the other hand against the body 210, and the hand pushing against the cover 220 opens the cover 220 to a side away from the body 210, in this process, the cover 220 can rotate relative to the body 210 through the rotating shaft mechanism 230, so as to take out the dust collecting device 100 from the body 210. Further, the cover 220 and the body 210 can be closed by a snap, a magnetic attraction, an adhesion, etc. for the present embodiment, the cover 220 is covered on the body 210 by the acting force of the rotating mechanism to the cover 220.

Referring to fig. 9 and 10, in one embodiment, the rotation shaft mechanism 230 includes a shaft cover 231, a rotation member 233, and a torsion spring 235. Referring also to fig. 8, in which the rotation member 233 may be screw-coupled to the cover 220 and the shaft cover 231 may also be screw-coupled to the body 210, when the user separates the cover 220 from the body 210 by hand, the rotation member 233 rotates relative to the shaft cover 231. Specifically, the shaft cover 231 is provided with a receiving groove and the receiving groove may be a sector groove so that the torsion spring 235 and the rotation member 233 are received in the receiving groove. With continued reference to fig. 11 and 12, in one embodiment, the rotation between the rotator 233 and the shaft cover 231 may be controlled by a torsion spring 235, wherein, with reference to fig. 10, the torsion spring 235 includes a first arm 2351, a second arm 2355, and a rotating portion 2353, the first arm 2351 is connected to the second arm 2355 through the rotating portion 2353, the first arm 2351 is connected to the inner side of the shaft cover 231, and the second arm 2355 is connected to the rotator 233. Further, the rotating member 233 further includes a hook 2331, and the second arm 2355 is connected to the hook 2331. In one embodiment, the rotating portion 2353 may be a spiral shape formed by a circle, and the first arm 2351 and the second arm 2355 are formed by extending two ends of the rotating portion 2353, so that when the second arm 2355 moves, the first arm 2351 can be driven by the rotating portion 2353 to move. In one embodiment, the torsion spring 235 can apply a force to the rotatable member 233 when the rotatable member 233 rotates relative to the shaft cover 231, so that the torsion spring 235 can help the cover 220 to achieve different force control when a user performs an opening or closing movement of the cover 220.

Referring to fig. 13 and 14, in an embodiment, when the cover 220 needs to be opened, the user holds the cover 220 by hand to open the cover with respect to the body 210, and referring to fig. 15, the rotating member 233 can rotate with respect to the shaft cover 231 from the first position to the third position through the second position, and the first arm 2351 and the second arm 2355 of the torsion spring 235 can be switched from the state of pressing the rotating portion 2353 to the open state. Specifically, when the rotating member 233 is in the first position, i.e., the cover 220 is closed on the body 210, the rotating member 233 is received in the receiving slot, and the torsion spring 235 is in a compressed state, i.e., the second support arm 2355 presses the first support arm 2351 through the rotating portion 2353, and at this time, the second support arm 2355 provides a pulling force to the cover 220. When the user wants to open the cover 220, the rotating member 233 generates resistance in the rotating process due to the pulling force, that is, the torsion spring 235 hinders the rotation of the rotating member 233, so that the user needs to give a force greater than the pulling force to the cover 220 to open the cover 220.

Referring to fig. 14, in one embodiment, during opening of the lid 220, when the rotator 233 rotates from the first position to the second position, the torsion spring 235 is transformed from a compressed state to an open state, i.e., the first arm 2351 and the second arm 2355 are open relative to the rotator 2353. When the user opens the cover 220 to the second position, the user does not need to give the acting force to the cover 220 to resist the pulling force of the second support arm 2355, at this time, the second support arm 2355 converts the pulling force to the cover 220 into a pushing force, the rotating part 233 generates power in the rotating process due to the action of the pushing force, namely, the torsion spring 235 can drive the rotating part 233 to rotate, and the opening action of the cover 220 can be realized even if the acting force to the cover 220 by the user is not provided. In an embodiment, with reference to fig. 15 and 16, the rotating member 233 can rotate continuously due to the power generated by the rotating member 233, and when the rotating member 233 is separated from the receiving slot and protrudes from the shaft cover 231, the rotating member 233 rotates to the third position, and the cover 220 can be kept in an open state due to the pushing force applied by the second support arm 2355 to the cover 220, so that the dust collecting device 100 can be taken out of the body 210 for discharging the garbage.

Referring to fig. 15 and 16, in an embodiment, when the garbage in the dust collecting device 100 is discharged, the user needs to put the dust collecting device 100 back into the body 210 to continue the garbage cleaning operation, i.e., the closing operation of the cover 220, and referring to fig. 8, when the cover 220 needs to be closed, the user presses the cover 220, and referring to fig. 13, the rotating member 233 can rotate relative to the shaft cover 231 from the third position to the first position through the second position, i.e., the first arm 2351 and the second arm 2355 of the torsion spring 235 can be switched from the open state to the state of pressing the rotating portion 2353. Specifically, when the rotating member 233 is in the third position, that is, the cover 220 is opened on the body 210 and abuts against the body 210, the torsion spring 235 is in an open state, that is, the first support arm 2351 and the second support arm 2355 are opened relative to the rotating portion 2353, when the user wants to close the cover 220, because the second support arm 2355 gives a pulling force to the cover 220, the rotating member 233 generates a resistance force in the rotating process due to the pulling force, that is, the torsion spring 235 hinders the rotation of the rotating member 233, so that the user needs to give an acting force greater than the pulling force to the cover 220 to close the cover 220.

Referring to fig. 15 and 16, in an embodiment, when the rotator 233 rotates from the third position to the second position, the torsion spring 235 is converted from the open state to a state of pressing the rotator 2353, that is, the second arm 2355 presses the first arm 2351 through the torsion spring 235. When the user closes the cover 220 to the second position, the user does not need to apply force to the cover 220 to resist the pulling force of the second support arm 2355, at this time, the second support arm 2355 converts the pulling force to the cover 220 into pushing force, the rotating part 233 generates power in the rotating process due to the action of the pushing force, namely, the torsion spring 235 can drive the rotating part 233 to rotate, and the closing action of the cover 220 can be realized even if no user applies force to the cover 220. In an embodiment, the rotating member 233 can rotate continuously due to the power generated by the rotating member 233, when the cover 220 covers the body 210, that is, the rotating member 233 rotates to the first position, the second support arm 2355 applies a pushing force to the cover 220 to keep the cover 220 in a covered state, so that the dust collecting device 100 can be sealed in the body 210 to suck the garbage by the dust collecting device 100.

Referring to fig. 9 and 10, in an embodiment, the rotating shaft mechanism 230 further includes a main gear 260 and a driven gear 270 that are in meshed transmission with each other, the main gear 260 is connected to the rotating member 233, the driven gear 270 is connected to the outer side of the shaft cover 231, the main gear 260 and the rotating member 233 may be in interference connection, when the rotating member 233 rotates, the main gear 260 may rotate along with the rotating member 233, and the main gear 260 may rotate the driven gear 270. Further, the rotating mechanism may further include a first nut 261 and a second nut 271, the first nut 261 is connected to the rotating member 233 to further prevent the main gear 260 from sliding off the rotating member 233, and the slave gear 270 may be in clearance connection with the shaft cover 231 such that the slave gear 270 is in a free-rotating state, and when the second nut 271 is connected to the shaft cover 231, the slave gear 270 may not slide off the shaft cover 231 during the rotation. Referring to fig. 15, particularly, since the second arm 2355 always maintains a pushing force on the cover 220 when the rotation member 233 rotates from the second position to the third position, so that the cover 220 is rapidly opened, the engagement transmission of the main gear 260 and the sub-gear 270 can slow down the rotation speed of the cover 220 relative to the body 210, so as to reduce the impact of the cover 220 on the body 210 and prevent the damage of parts. With reference to fig. 17 and 18, further, damping oil may be added between the master gear 260 and the slave gear 270, that is, lubricating oil with relatively high viscosity is used to further slow down the rotation speed of the cover 220 relative to the body 210 and to achieve a better effect of slowing down the impact.

Similarly, during the closing process of the cover 220, since the rotating member 233 rotates from the second position to the first position, the second arm 2355 always has a pushing force on the cover 220 to enable the cover 220 to be quickly closed, the engagement transmission between the main gear 260 and the secondary gear 270 can slow down the rotating speed of the cover 220 relative to the body 210, so as to reduce the impact of the cover 220 on the body 210 and prevent the damage of the components. Further, damping oil, i.e., lubricating oil with relatively high viscosity, may be added between the master gear 260 and the slave gear 270 to further slow down the rotation speed of the cover 220 relative to the body 210, so that the impact of the cover 220 covering the body 210 is reduced.
