(1) when the button 740 for opening the trash can cover 150 is pressed, the control module 750 starts the motor 510, the motor 510 drives the trash can cover 150 to be opened through the meshing of the external gear 520 and the transmission piece 530, until the trash can cover 150 is completely opened, the trash can cover 150 triggers the first travel switch 710, and the control module 750 turns off the motor 510; during the period, when the trash can cover 150 is fully opened and no obstacle is detected in front by the infrared detection module 730 within a certain time, the control module 750 starts the motor 510, and the motor 510 drives the trash can cover 150 to be turned back to the original position through the engagement of the external gear 520 and the transmission member 530.

(2) When the button 740 for closing the lid 150 is pressed, the control module 750 activates the motor 510, the motor 510 drives the lid 150 to flip back through the engagement of the external gear 520 with the transmission 530 until the lid 150 is fully reset, the lid 150 activates the second travel switch 720 and the control module 750 deactivates the motor 510.

(3) When the dust collection function is started by pressing, the control module 750 starts the electric fan 410 and does not start the motor 510; referring to fig. 13, the airflow carrying the garbage sequentially passes through the dust collection hose 420, the main air inlet C and the air inlet duct C and then enters the connection cavity B, wherein heavier garbage enters the garbage inner barrel 200 from the connection cavity B through the discharge port d, the material guide member 122 and the material discharge port a under the self-weight of the heavier garbage, and lighter garbage flows to the labyrinth type gas distribution module 300 along with the airflow; then, the labyrinth air duct 320 blocks light garbage from entering the air outlet duct D, and the labyrinth air duct 320 divides the air flow into two parts, wherein most of the air flow flows from the first air outlet i of the labyrinth air duct 320 to the filtering device 330, a small part of the air flow carries tiny garbage from the second air outlet j to the garbage inner barrel 200, the air flow also brings the hair intercepted on the labyrinth air duct 320 into the garbage inner barrel 200, and the garbage enters the garbage inner barrel 200 after passing through the material outlet D, the material guiding member 122 and the material dropping opening a; then, after the airflow entering the garbage inner barrel 200 sequentially passes through the blanking port a, the material guiding member 122 and the material outlet d, the airflow reenters the base 310 from the second air outlet g and flows to the filtering device 330; finally, the airflow filtered by the filtering device 330 enters the air outlet pipeline D from the first air outlet f of the base 310, and flows to the outside after passing through the air outlet pipeline D and the main air outlet b.

(4) When the dust suction function is pressed off, the control module 750 turns off the electric fan 410 and does not start the motor 510.

Compared with the prior art, the garbage can not only can be opened to lose garbage, but also can suck dry/wet garbage into the garbage inner barrel 200, so that the garbage can is convenient to clean. More importantly, the garbage can adopts the labyrinth type gas distribution module 300, so that the condition that all airflow carrying garbage enters the inner can is effectively avoided, the plastic bag is prevented from being lifted, the fixing frame is prevented from being in direct contact with the garbage for a long time, the frequency of cleaning the fixing frame is reduced, and the garbage can is convenient to use. Moreover, the labyrinth gas distribution module 300 can be disassembled, is convenient to clean or replace, and is helpful for ensuring the cleanness and sanitation of gas discharged from the garbage can. In addition, when the garbage can sucks liquid, the liquid is blocked by the first guide plate 321 and the second guide plate 322 at the labyrinth air duct 320 and flows into the garbage inner can 220 under the guide action of the guide plates, so that the liquid is prevented from entering the air outlet pipeline D, and the electric fan 410 is prevented from being burnt out.

The above-mentioned embodiments only express several embodiments of the present invention, and the description thereof is more specific and detailed, but not construed as limiting the scope of the invention. It should be noted that, for a person skilled in the art, several variations and modifications can be made without departing from the inventive concept, which falls within the scope of the present invention.
