Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0028] In addition, in the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0029] Please see Figures 1-5 As shown, this utility model discloses a covered appliance, comprising a body 1, a cover 2, and a pressing drive mechanism. The body 1 has a receiving space and an opening communicating with the receiving space. One side of the cover 2 is movably connected to the body 1 for opening or closing the opening of the body 1. The pressing drive mechanism includes a button 3 pressable on the body 1 and a connecting rod 4. The connecting rod 4 is located near the button 3 and rotatably connected to the body 1. The connecting rod 4 has a locking structure for locking the cover 2 when closed. Specifically, one end of the locking structure is fixed to the connecting rod 4, and the other end can lock the cover 2 when closed. The locking structure engages or disengages from the cover 2 by rotating with the connecting rod 4. The button 3 is driven to the connecting rod 4 to drive the connecting rod 4 to rotate. When the button 3 is pressed, the button 3 moves downward and drives the connecting rod 4 to rotate, causing the locking structure on the connecting rod 4 to rotate away from the cover 2 to engage with the latch on the cover 2.

[0030] In a preferred embodiment, the locking structure includes multiple latches 5 arranged in parallel along the extension direction of the connecting rod 4. One end of each latch 5 is fixedly connected to or integrally formed with the connecting rod 4, and the other end of each latch 5 extends toward the cover 2 and is provided with a locking part 51. The side wall of the cover 2 is provided with a groove 21 corresponding to each latch 5 for engaging with the locking part 51. The locking part 51 of each latch 5 is provided with a guide slope 511, which is used to slide and engage with the edge of the cover 2 when the cover 2 is closed, so as to guide the locking part 51 into the groove 21 of the cover 2. Therefore, the locking structure and the cover 2 can achieve multi-point locking, which significantly improves the stability of the cover 2 in the closed state, effectively avoids the problem of the cover 2 tilting on one side, which is common in traditional single-point locking designs, and ensures the reliability and sealing of the cover 2 in various usage scenarios. In this embodiment, the number of buckles 5 is set to two, and the two buckles 5 are fixed at both ends of the connecting rod 4 respectively, but the number and distribution of buckles 5 are not limited to this.

[0031] In this embodiment, the transmission connection between the button 3 and the connecting rod 4 is as follows: the button 3 is provided with an active block 33, and the outer side of the connecting rod 4 is provided with a first driven member 41 and a second driven member 42 distributed circumferentially. The active block 33 is engaged between the first driven member 41 and the second driven member 42, and the active block 33 pushes against the first driven member 41 or the second driven member 42 as the button 3 moves, thereby driving the connecting rod 4 to rotate. The direction of the rotation axis of the connecting rod 4 is perpendicular to the pressing direction of the button 3. Preferably, the active block 33 is provided with a first inclined surface 331 that contacts and engages with the first driven member 41 and a second inclined surface 332 that contacts and engages with the second driven member 42, so that the active block 33 pushes against the first driven member 41 through the first inclined surface 331 or pushes against the second driven member 42 through the second inclined surface 332. The button 3 specifically includes a button head 31 and a support column 32. One end of the support column 32 is fixed to the button head 31, and the other end of the support column 32 extends along the direction in which the button 3 is pressed. The driving block 33 is fixed to the support column 32. The button head 31, the support column 32, and the driving block 33 can be integrally formed or separately formed and assembled together. The first driven member 41 and the second driven member 42 are respectively rib structures extending along the axial direction of the connecting rod 4 and integrally formed with the connecting rod 4. In this way, the first driven member 41 and the second driven member 42 can also act as reinforcing ribs, thereby improving the strength of the connecting rod 4, so that the connecting rod 4 will not deform when the button 3 is pressed to drive the connecting rod 4 to rotate, and the button 3 and the connecting rod 4 always maintain a transmission connection.

[0032] In this embodiment, a first elastic element 6 is abutting against the button 3 and the body 1. The first elastic element 6 is used to drive the button 3 to reset upward. Specifically, the button head 31 of the button 3 is movably sleeved in the guide groove 111 provided on the top of the body 1. The first elastic element 6 is a helical spring structure. The upper end of the first elastic element 6 is sleeved on the bottom of the support column 32 and abuts against the active block 33. The lower end of the first elastic element 6 is sleeved on the first limiting seat 13 correspondingly provided on the body 1.

[0033] In a preferred embodiment, each buckle 5 is abutted against the body 1 by a second elastic element 7. The second elastic element 7 applies an elastic preload to the buckle 5 along the direction of engagement between the buckle 5 and the cover 2, thereby improving the engagement effect of the buckle 5 on the cover 2. Specifically, the second elastic element 7 is a helical spring structure, with one end limited to the side of the buckle 5's engagement portion 51 facing away from the cover 2, and the other end limited to the corresponding second limiting seat (not shown in the figure) provided on the body 1.

[0034] In this embodiment, the cover 2 is rotatably connected to the body 1, and a third elastic element 9 abuts against the cover 2 and the body 1. This third elastic element 9 drives the cover 2 to flip open when the locking structure separates from the cover 2. Specifically, one end of the cover 2 is rotatably connected to the body 1 via a pivot 8. The third elastic element 9 is a torsion spring structure and is sleeved on the pivot 8, with both ends of the third elastic element 9 abutting against the cover 2 and the body 1 respectively. The aforementioned slot 21 is located at the other end of the cover 2, with one end and the other end of the cover 2 being opposite ends.

[0035] In a preferred embodiment, the cover 2 is provided with a sealing ring 10, such as... Figure 5 As shown. When the cover 2 is closed, the sealing ring 10 is sealed and fitted around the opening of the body 1.

[0036] In this embodiment, the body 1 includes an inner liner 11 with a receiving space and an opening, and an outer shell 12 fitted over the inner liner 11. A pressing drive mechanism is disposed in the inner liner 11 and located between the inner liner 11 and the outer shell 12. The outer shell 12 has a clearance opening 121 corresponding to the button 3. Specifically, the clearance opening 121 is located on the top cover portion of the outer shell 12. The cover 2 is rotatably connected to the inner liner 11, and the outer shell 12 avoids the connection between the cover 2 and the inner liner 11.

[0037] In this embodiment, the present invention relates to a trash can, specifically a kitchen countertop trash can. The aforementioned body 1 is the trash can body, and the aforementioned lid 2 is the trash can lid. Therefore, the lid 2 can be flipped open and closed along the top edge of the body, realizing the functions of trash disposal and sealing to prevent odors. In other embodiments, the present invention relates to a storage box or medicine cabinet, etc.

[0038] The opening principle of the lid 2 of this utility model is as follows:

[0039] When the user presses button 3 downwards, button 3 moves downwards along the guide groove and compresses the first elastic element 6. Meanwhile, the active block 33 pushes the second driven element 42 on the connecting rod 4, causing the connecting rod 4 and its various latches 5 to rotate clockwise, compressing the second elastic element 7. This causes the engaging parts 51 of each latch 5 to disengage from the slots 21 of the cover 2 and unlock. At this time, the cover 2 instantly flips upwards and opens under the pre-stored energy of the third elastic element 9. After releasing button 3, the first elastic element 6 releases its elastic potential energy, pushing button 3 upwards to reset. The active block 33 pushes the first driven element 41, causing the connecting rod 4 and its various latches 5 to rotate counterclockwise, causing the engaging parts 51 of each latch 5 to move back to the pre-locked position. During this process, the first elastic element 6 controls the button 3 to reset, and the second elastic element 7 drives the latches 5 to rotate counterclockwise. The two work together to ensure the latches 5 are accurately reset. When the first elastic element 6 is omitted, the second elastic element 7 can simultaneously perform the functions of rotating the latch 5 and resetting the button 3. Conversely, if the second elastic element 7 is omitted, the first elastic element 6 can also simultaneously perform the functions of resetting the button 3 and rotating the latch 5. Therefore, the first elastic element 6 and the second elastic element 7 can work together, or one of them can be selected.

[0040] The closing and locking mechanism of cover 2 works as follows:

[0041] When the cover 2 is closed, its edge first contacts the guide slope 511 of the engaging parts 51 of each latch 5. The downward pressure of the cover 2 is decomposed into a horizontal component force through the guide slope 511, driving the latch 5 and connecting rod 4 to rotate clockwise by a small angle, while compressing the energy stored in the second elastic element 7. When the cover 2 is fully closed, the latch 5 rotates counterclockwise under the action of the elastic potential energy released by the second elastic element 7, so that its engaging part 51 accurately engages with the slot 21 of the cover 2, forming a mechanical lock. This process achieves adaptive avoidance and automatic locking when the cover 2 is closed through the guiding effect of the guide slope 511 and the synergistic effect of the energy stored in the second elastic element 7. In addition, the user can also actively trigger the avoidance mechanism by pressing the button 3: when the button 3 is pressed, it drives the connecting rod 4 and latch 5 to rotate clockwise, so that the engaging part 51 disengages from the edge of the cover 2 in advance, at which time the cover 2 can close without resistance. After releasing the button 3, the latch 5 resets and locks the cover 2 under the action of the second elastic element 7.

[0042] The part of this utility model with a lid is the same as or can be implemented using existing technology.

[0043] The above embodiments are only used to further illustrate a covered appliance of the present utility model, but the present utility model is not limited to the embodiments. Any simple modifications, equivalent changes and modifications made to the above embodiments based on the technical essence of the present utility model shall fall within the protection scope of the technical solution of the present utility model.
