When the touch part 300 is touched, it rotates from a first position to a second position, so that the switch part 200 rotates and the cover body 101 is disengaged and opened from the switch part 200.

[0048] According to the lid opening structure, trash can lid assembly and trash can provided by the above embodiment, by arranging the lid opening structure on the lid assembly, when the triggering part in the lid opening structure is triggered by the contraction of the drawstring of the trash bag, the triggering part can be rotated from the first position to the second position, so that the switch part in contact with the triggering part rotates, and finally the lid body arranged on the lid assembly is disengaged from the switch part and opened, so that the sealed trash bag can be taken out of the trash can. The lid opening structure provided by this embodiment is simple in structure and low in cost.

[0049] Next, we will refer to Figures 2 to 10 The various parts of the above-mentioned cover opening structure in this exemplary embodiment are described in more detail.

[0050] In one embodiment, the lid opening structure is disposed on a barrel cover assembly 100, and the barrel cover assembly 100 includes an annular sleeve portion 102 and a cover body 101 pivotally connected to the sleeve portion 102, and the sleeve portion 102 has an opening 1021 on the top of the side wall; the lid opening structure may include a switch portion 200 and a touch portion 300.

[0051] The switch part 200 is rotatably connected to the opening 1021 and can be snap-connected with the cover body 101; the touch part 300 is rotatably connected to the opening 1021, is located below the switch part 200, and contacts the switch part 200. When the touch part 300 is touched, it rotates from a first position to a second position, so that the switch part 200 rotates and the cover body 101 is disengaged and opened from the switch part 200.

[0052] Specifically, Figure 8 As shown, in order to enable the opening cover structure to be better installed on the barrel cover assembly 100, the barrel cover assembly 100 includes an annular sleeve portion 102, the annular sleeve portion 102 has a certain thickness, and an opening 1021 is provided at the top of the side wall of the sleeve portion 102, the opening 1021 is used to place the opening cover structure, and the sleeve portion 102 is connected to a cover body 101, and the cover body 101 can be connected to the rotating shaft on the sleeve portion 102 through a torsion spring, but is not limited to this, so that the cover body 101 can be automatically opened after being disengaged, and is specifically not limited to this.

[0053] In addition, if Figure 2 As shown, the cover opening structure includes a switch part 200 and a touch part 300, the switch part 200 is movably connected to the opening 1021 and can be engaged with the cover body 101. When the switch part 200 rotates and deflects, the cover body 101 engaged with the switch part 200 will be disengaged, so that the cover body 101 is automatically opened; the touch part 300 is also movably connected to the position of the opening 1021 and is located below the switch part 200, and part of the touch part 300 is in contact with the switch part 200. When the touch part 300 is touched, for example, the touch part 300 is triggered by pulling the drawstring of a garbage bag placed in a garbage bin, and there is no specific limitation; the touch part 300 moves from the first position to the second position, and at this time, the switch part 200 in contact with the touch part 300 will also undergo a corresponding deflection, so that the cover body 101 is disengaged from the switch part 200 and automatically opened. The first position is the position of the trigger rod in the vertical direction, and the second position is the position to which the trigger rod 302 is rotated after being triggered by the draw rope of the garbage bag, that is, there is a preset angle between the first position and the second position, which can be set according to actual conditions and is not specifically limited here.

[0054] In one embodiment, the switch portion 200 includes a button portion 201 and an inclined portion 202. The button portion 201 is movably connected to the sleeve portion 102 at the opening 1021, and the button portion 201 is provided with a buckling portion (not shown in the figure) adapted to a portion of the edge of the cover body 101; the inclined portion 202 is located below the button portion 201, and the inclined portion 202 can drive the button portion 201 to rotate by its own offset, so that the cover body 101 is separated from the buckling portion and opened.

[0055] Specifically, Figures 3 to 5 As shown, in order to facilitate the description of the switch part 200, the switch part 200 is split into a button part 201 and an inclined surface part 202, and the inclined surface part 202 is located below the button part 201; the button part 201 is provided with shaft holes 203 on both sides, and the shaft holes 203 are connected to the shaft 204 of the sleeve part 102 located at the opening 1021, so that the button part 201 can be movably connected with the sleeve part 102, and the specific connection method is not limited to this, and can refer to the design of the prior art. In addition, the button part 201 is also provided with a buckle part, which can be in a buckle shape, but is not limited to this. The buckle part can be adapted to buckle with a part of the edge of the cover body 101. It should be noted that the buckle part can also be provided on the cover body 101, for the buckle connection between the cover body and the button part, and can be provided according to the specific manufacturing process, and no specific limitation is made here.

[0056] In order to facilitate the relative movement of the inclined portion 202 and the touch portion 300, the inclined portion 202 can be specifically set to a concave shape, that is, when the switch portion 200 is in the original position, the touch portion 300 is located in the concave part of the concave surface. When the touch portion 300 is touched, the touch portion 300 will move upward along the concave part of the concave surface, so that the inclined portion 202 is offset, so as to drive the button portion 201 connected to the inclined portion 202 to rotate, and finally the cover body 101 is disengaged from the buckling portion on the button portion 201 and automatically opened.

[0057] In one embodiment, the opening 1021 has a protrusion 1024 at a position below the button part 201, and the protrusion 1024 is used to fix one end of an elastic member (not shown in the figure); and the other end of the elastic member is connected to the button part 201, and the elastic member is used to reset the button part 201.

[0058] For example, Fig. 9As shown, when the switch part 200 is rotated to make the cover body 101 disengage and open, in order to make the switch part 200 recover as soon as possible so that the cover body 101 can be manually re-fastened on the fastening part on the switch part 200, an elastic member is installed below the button part 201. The elastic member is specifically a spring, which is not limited here; specifically, a protrusion 1024 is provided at the opening 1021 and below the button part 201, and the protrusion 1024 is used to fix one end of the spring and connect the other end of the spring to the bottom surface of the button part 201. In order to ensure the stability of the reset of the button part 201, two springs can be symmetrically provided on the bottom surface of the button part 201, which is not limited here.

[0059] In addition, when the switch part 200 rotates relative to the trigger part 300 from the first position to the second position, the spring also changes from an undeformed state to an extended state. When the cover body 101 is released and the trigger part 300 stops being triggered, the spring will drive the switch part 200 to return to its original position, so that the cover body 101 and the snapping part of the switch part 200 can be snapped together again.

[0060] In one embodiment, the trigger portion 300 includes a rotating shaft 301, a trigger rod 302 and a trigger head 303. The rotating shaft 301 is movably connected to the sleeve portion 102 at the opening 1021; the trigger rod 302 is vertically connected to the rotating shaft 301, and when the trigger rod 302 is triggered, it can rotate from a first position to a second position, that is, from Figure 3 Shown location to Figure 4 the touch head 303 is disposed on the shaft 301 and can be rotated indirectly by the rotation of the touch rod 302, so that the inclined portion 202 in contact with the touch head 303 is offset.

[0061] Specifically, Figure 3 , 4 6, in order to more clearly understand the triggering part 300, the triggering part 300 is divided into a rotating shaft 301, a triggering rod 302 and a triggering head 303. The rotating shaft 301 is horizontally arranged, the triggering rod 302 is vertically connected to the rotating shaft 301, and the triggering head 303 is also arranged on the rotating shaft 301, and the triggering rod 302 and the triggering head 303 are oriented in different directions on the rotating shaft 301.

[0062] When the trigger rod 302 is triggered by, for example, pulling the drawstring of a garbage bag placed in a garbage bin, the trigger rod 302 will rotate from the first position to the second position, thereby causing the rotating shaft 301 located at the opening 1021 and movably connected to the sleeve portion 102 to rotate, and the rotating shaft 301 will drive the trigger head 303 disposed thereon to rotate, thereby causing the inclined portion 202 in contact with the trigger head 303 to shift, thereby driving the button portion 201 to rotate, so that the cover body 101 and the buckling portion on the button portion 201 are disengaged and automatically opened.

[0063] In one embodiment, the rotating shaft 301 is also connected to a reset rod 304 parallel thereto, and a reset elastic member 500 is wound around the reset rod 304 and the rotating shaft 301 , and the reset elastic member 500 can restore the triggering portion 300 from the second position to the first position.

[0064] For example, Figure 3 , 4 As shown in FIG. 6 , a reset rod 304 is also provided on the rotating shaft 301, and the axial direction of the reset rod 304 is parallel to the axial direction of the rotating shaft 301. In addition, a reset elastic member 500 is wound around the reset rod 304 and part of the rotating shaft 301, which can be a reset torsion spring, which is not limited here, and one end of the reset elastic member 500 is located on a mounting frame 400. For example, in one example, the opening cover structure also includes a mounting frame 400, and the mounting frame 400 is located below the rotating shaft 301, and the mounting frame 400 is used to fix one end of the reset elastic member 500.

[0065] When the trigger rod 302 is triggered to rotate from the first position to the second position, the rotating shaft 301, the trigger head 303, and the reset rod 304 are also deflected accordingly. After the trigger rod 302 is triggered, in order to enable the trigger part 300 including the trigger rod 302 to recover as soon as possible, a reset torsion spring is provided on the trigger part 300, so that the trigger part 300 can automatically recover after the triggering. The reset torsion spring is specifically provided on the rotating shaft 301 and the reset rod 304, and the end of the reset torsion spring close to the rotating shaft 301 is fixed on the mounting bracket 400. The specific installation method of the reset torsion spring can refer to the prior art and is not limited here. It should be noted that the mounting bracket 400 is not only used to fix the reset torsion spring, but also can be used to cover the internal structure of the trigger part 300, so that the trash can lid assembly with the opening structure is more beautiful.

[0066] In one example, the mounting frame 400 includes a bottom plate 401 , and the bottom plate 401 has a strip-shaped hole 402 , and the trigger rod 302 is used to pass through the strip-shaped hole 402 to achieve rotation at a preset position.

[0067] Specifically, Figure 7 As shown, in order to realize the free rotation of the trigger rod 302 within a certain angle, a strip-shaped through hole is opened on the bottom plate 401 of the mounting frame 400, and the trigger rod 302 is allowed to pass through the strip-shaped hole 402, and can realize automatic rotation between a first position and a second position, wherein the first position and the second position are the preset positions, and the first position and the second position are based on enabling the cover body 101 to be released and opened, and can be set according to actual conditions, and no specific restrictions are made here.

[0068] According to the above-mentioned opening cover structure, by arranging the opening cover structure on the barrel cover assembly, when the trigger part in the opening cover structure is triggered, the switch part in contact with the trigger part can rotate, so that the cover body arranged on the barrel cover assembly and the switch part are disengaged and opened, so as to facilitate the replacement of the garbage bag. The opening cover structure is not only simple in structure and easy to manufacture, but also low in cost.

[0069] This exemplary embodiment also provides a trash can lid assembly 100. Figure 2 , 8 As shown in , the barrel cover assembly 100 includes an annular sleeve portion 102 , a cover body 101 , a switch portion 200 , and a touch portion 300 .
