[0035] With reference to FIGS. 1 to 4, a foot-operated flip-top trash can according to one embodiment of the present disclosure will be described in detail below. The foot-operated flip-top trash can comprises a receiving assembly 10 comprising a can body 11 having a receiving cavity 1101 and an exposure opening 1102 formed at a top end of the can body 11 and communicated with the receiving cavity 1101. The trash bag is placed in the receiving chamber 1101 in a stretched manner, and the edge portion thereof is extended from the exposure opening 1102 to overlap the top portion of the can body 11.

[0036] The foot-operated flip-top trash can comprises a covering-closing mechanism 20 comprising a covering-closing assembly 21 and at least one connector 22, the covering-closing assembly 21 comprises a main cover 211 and an auxiliary cover 212, the connector 22 is rotatably mounted to the receiving assembly 10, the main cover 211 is mounted to the connector 22 and rotatable together with the connector 22, the auxiliary cover 212 is inserted and matched with the connector 22 and rotatable relative to the main cover 211 in a coaxial manner with the connector 22, and the covering-closing assembly 21 is rotatable with the connector 22 together to open or close the exposure opening 1102. The auxiliary cover 212 has a circular opening 21201 having a size smaller than the size of the main cover 211, and the main cover 211 is rotatable relative to the auxiliary cover 212 to open or close the circular opening 21201. In a case where the covering-closing assembly 21 seals the exposure opening 1102, the auxiliary cover 212 is corresponding to the opening edge of the exposure opening 1102 and is clamped on the edge portion of the trash bag with the upper end of the can body 11 to fix the trash bag, and the main cover 211 is placed on the upper surface of the auxiliary cover 212 to seal the circular opening 21201 to seal the exposure opening 1102 by sealing the circular opening 21201. The auxiliary cover 212 can be pushed to drive the main cover 211 to rotate away from the exposure opening 1102 together, and the maximum rotation angle of the auxiliary cover 212 is consistent with the maximum rotation angle of the main cover 211.

[0037] With reference to FIGS. 4 to 11, the foot-operated flip-top trash can further comprises a trigger mechanism 30 comprising a pedal 31 rotatably mounted on a low end of the can body 11 and at least one top-pusher 32 rotatably connected to one end of the pedal 31.

[0038] The connector 22 has a clamping channel 2201, an end portion of the top-pusher 32 away from the pedal 31 is clamped with the clamping channel 2201. The clamping channel 2201 comprises a pushed portion 22011 and a locking portion 22012 communicated with the pushed portion 22011, the locking portion 22012 being formed by extending a bottom end of the pushed portion 22011 and forming an included angle of not less than 90 with the pushed portion 22011. In a case where the top-pusher 32 is driven upward with the pedal 31 being stepped on and rotated, and the inner wall of the pushed portion 22011 is top-pushed to drive the main cover 211 away from the circular opening 21201 of the auxiliary cover 212 covering the opening edge of the exposure opening 1102. In a case where the top-pusher 32 is clamped with the pushed portion 22011 and the pedal 31 is not applied with an external force, the main cover 211 can rotate to the circular opening 21201 under the action of its own gravity to seal the exposure opening 1102 by closing the circular opening 21201. After the circular opening 21201 of the auxiliary cover 212 covering the opening edge of the exposure opening 1102 is opened by stepping on the pedal 31 with the foot, the main cover 211 can be pushed to continue to rotate away from the circular opening 21201 and be locked at a position where the rotation angle is not less than 90 by the top-pusher 32 being clamped with the locking portion 22012.

[0039] In this way, through the design of the auxiliary cover 212, the trash bag in the receiving cavity 1101 can be effectively fixed to prevent the trash bag from slipping down and conducive to putting the trash. In addition, the main cover 211 can be rotated twice successively and finally locked at a position with an angle of not less than 90, so that the circular opening 21201 of the auxiliary cover 212 covering the opening edge of the exposure opening 1102 is completely opened, effectively avoiding the situation that the trash is not easily disposed due to the incomplete opening of the circular opening 21201, and during the trash disposed process, there is no need to step on the pedal 31 throughout the entire process, thereby increasing the convenience of trash disposed. In addition, since both the main cover 211 and the auxiliary cover 212 can be rotated to a position at an angle of not less than 90, the exposure opening 1102 can be completely opened to replace the trash bag.

[0040] Optionally, two connectors 22 are provided and the two connectors 22 are spaced apart by a predetermined distance, the two connectors 22 are rotatably mounted to the receiving assembly 10 in such a manner that the ends of the two connectors 22 close to each other are inserted into the receiving assembly 10, and the other ends of the two connectors 22 away from each other are inserted into the auxiliary cover 212 and can be rotated relative to the auxiliary cover 212, and the connectors 22 are connected to the main cover 211 by at least one fastener. The number of top-pushers 32 is consistent with the number of connectors 22, and the two top-pushers 32 are respectively locked into the two clamping channels 2201 of the connectors 22. In this way, when the pedal 31 is pressed, the two top-pushers 32 are simultaneously driven by the pedal 31 to drive the main cover 211 away from the circular opening 21201 by top-pushing the connectors 22 respectively, thereby applying a uniform force to the main cover 211 and ensuring that the circular opening 21201 can be fully opened.

[0041] Optionally, a circular groove 21202 is formed on the side of the auxiliary cover 212 away from the main cover 211, and the circular groove 21202 is located on the outer periphery of the circular opening 21201. When the auxiliary cover 212 covers the opening edge of the exposure opening 1102, the upper end of the can body 11 is inserted into the circular groove 21202 to clamp the edge portion of the trash bag, thereby effectively fixing the trash bag, and effectively preventing the edge portion of the trash bag overlapping the top portion of the can body 11 from sliding into the receiving cavity 1101, thus preventing affecting putting the trash. In addition, in a case where the edge portion of the trash bag is overlapped with the top portion of the can body 11 and hangs down on the outer peripheral wall of the can body 11, the auxiliary cover 212 is sleeved with the upper end of the can body 11, so that the edge portion of the trash bag hanging from the outer peripheral wall of the can body 11 is hidden in the circular groove 21202, thereby improving the aesthetics during using.

[0042] Further, a mounting groove 1103 and a through opening 1104 communicated with the mounting groove 1103 are formed at the bottom of the can body 11. The pedal 31 is rotatably attached to the mounting groove 1103, and one end of the pedal 31 away from the pusher 32 is extended from the side portion of the can body 11 to the outside through the through opening 1104 for being stepped. In a case where the can body 11 is supported by the ground, one end of the pedal 31 extending from the through opening 1104 is spaced from the ground by a predetermined distance, and one end of the pedal 31 connected with the top-pusher 32 is spaced from the top wall of the mounting groove 1103 by a predetermined distance, so as to ensure that in a case where one end of the pedal 31 extending from the through opening 1104 is stepped on, the pedal 31 can be provided with sufficient rotation space to ensure the foot-operated flip-top trash can being normally used.

[0043] The receiving assembly 10 further comprises a bag-storage body 12, the bag-storage body 12 is mounted in the can body 11, the bag-storage body 12 has a bag-storage cavity 1201 and an access opening 1202 communicated with the bag-storage cavity 1201, the bag-storage cavity 1201 is for storing unused trash bags, the access opening 1202 is for taking unused trash bags in the bag-storage cavity 1201 or putting unused trash bags into the bag-storage cavity 1201.

[0044] It is worth mentioning that the access opening 1202 is formed at the top end of the bag-storage body 12 and adjacent to the exposure opening 1102. In a case where the auxiliary cover 212 covers the opening edge of the exposure opening 1102, the access opening 1202 is closed by the auxiliary cover 212 to prevent the strange smell from the trash put into the trash bag stretched in the receiving cavity 1101 from passing through the exposure opening 1102 and from the access opening 1202 to the bag-storage cavity 1201, and prevent resulting in pollution of the trash bag stored in the bag-storage cavity 1201. In addition, based on the position design of the access opening 1202, the taking-and-placing operation of the unused trash bags are all in the vertical direction, so that the bending range of the user can be as small as possible, and the convenience of operation is increased.

[0045] Optionally, the bag-storage body 12 and the portion of the pedal 31 extending from the through opening 1104 are disposed facing away, and the connector 22 is rotatably mounted on the top portion of the bag-storage body 12.

The cover body 512 is mounted on the box body 511 so as to be able to open or close the placement opening 5103 so as to replace the filter.

[0056] In one embodiment, the box member 51 further has a placement opening 5103 communicated with the placement space 5101, the placement opening 5103 is formed on a side wall of the box member 51 away from the rotation axis of the main cover 211 or a side wall of the box member 51 located in the radial direction of the rotation shaft of the main cover 211, and the placement opening 5103 is for the filter to be withdrawn or inserted into the placement space 5101 so as to replace the filter by drawing and inserting the filter.

[0057] In another embodiment, the box member 51 is detachably mounted to the main cover 211, and the filter is replaced by detaching the box member 51.

[0058] Further, the deodorizing box 50 further comprises a start-end date display member 52 comprising a date identifier 521 rotatably mounted to the box member 51, and a start-end date display assembly 522, and twelve month-identifiers are arranged and equally spaced on a surface of date identifier 521 with an axis of the date identifier 521 being a center of the month-identifiers. The start-end date display assembly 522 comprises a start-date display structure 5221 and an end-date display structure 5222, both of which are disposed on the box member 51. The date identifier 521 is rotatable, so that any one of the month-identifiers on the surface of the date identifier 521 is corresponding to the start date display structure 5221 or the end date display structure 5222. In a case where one month-identifier on the surface of the date mark 521 is corresponding to the start date display structure 5221, the other month-identifier separated by a predetermined distance from the corresponding month mark is corresponding to the end date display structure 5222, and the number of months between the months represented by the two month-identifiers is consistent with the validity period of the filter, so as to prompt the user to replace the filter in time.

[0059] Optionally, the date identifier 521 is rotatably attached to the placement space 5101 and partially protrudes from the placement space 5101, and the portion of the date identifier 521 protruding from the placement space 5101 can be applied with force so as to rotate the entire portion. Both the start date display structure 5221 and the end date display structure 5222 are embodied as observation holes formed in one side wall of the box member 51 away from the main cover 211. In a case where the main cover 211 is rotated away from the exposure opening 1102, the user can see the month-identifier corresponding to the corresponding observation hole on the surface of the date identifier 521 through the observation hole, so as to know the replacement month of the filter.

[0060] Alternatively, the date identifier 521 is rotatably mounted on a side wall of the box member 51 away from the main cover 211, and both the start date display structure 5221 and the end date display structure 5222 are embodied as indicating fingers provided on the side wall of the box member 51 away from the main cover 211. In a case where the main cover 211 is rotated away from the exposure opening 1102, the user can see the specific one month pointed by the indicating finger on the surface of the date identifier 521, thereby knowing the month of replacement of the filter.
