Abstract
Description
Technical Field
[0001] This utility model belongs to the field of trash can technology, and specifically refers to an assembled trash can. Background Technology
[0002] Trash cans are commonly used containers for storing garbage in daily life. When using them, garbage bags are placed inside, and when there is too much garbage, the garbage bags can be tied up and thrown away.
[0003] Currently, most existing trash cans are made of plastic through direct injection molding, which takes up a lot of space and is inconvenient to transport and store. To solve this problem, a trash can that can be folded vertically for storage has been designed. However, the structure of this trash can must be wider at the top and narrower at the bottom, and part of the trash can body must be made of flexible material. This affects the capacity and support of the trash can, and it cannot be used for trash cans made of metal or other hard materials.
[0004] To address this issue, US Patent Application No. US18057638 discloses a foldable trash can, comprising a base, a front side panel, a rear side panel, a left side panel, and a right side panel. Each of the four side panels has a connecting rail on both sides, and the connecting rails of two side panels are engaged and fixed by panel fixing clips.
[0005] The aforementioned collapsible trash can has the following two problems:
[0006] 1. The two side panels are fixed together by panel fixing clips. However, during transportation or storage, the panel fixing clips are small and easily lost, which makes it impossible to connect the four side panels when the foldable trash can is needed.
[0007] 2. Panel fixing clips are generally made of plastic, which can easily become brittle and break after prolonged use, affecting the connection between the side panels. Utility Model Content
[0008] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide an assembled trash can with a more secure and stable connection that does not require additional fixing clips.
[0009] The objective of this utility model can be achieved through the following technical solutions:
[0010] An assembled trash can includes a base, an upper frame, a lid assembly, and at least two side plates connected in sequence. The lower ends of the side plates are all inserted and fixed into the lower slots of the base, and the upper ends are all inserted and fixed into the upper slots of the upper frame. The lid assembly is connected to the upper frame. The characteristic feature is that a first joint and a second joint are respectively provided at the connection points of two adjacent side plates. The second joint can be inserted vertically into the first joint, and the first joint can cooperate with the second joint to achieve horizontal fixation.
[0011] In this modular trash can, the second joint on adjacent side panels is inserted into the first joint to connect the two adjacent side panels. This eliminates the need for fixing clips or other accessories, effectively preventing problems such as the side panels failing to connect due to lost clips. Furthermore, eliminating clips also prevents issues like clips becoming brittle, breaking, or deforming, which could weaken the connection between the side panels. The first joint directly connects to the second joint of the adjacent side panel, resulting in a simpler structure, easier assembly, and higher strength and stability after assembly.
[0012] In the aforementioned assembled trash can, each side panel has a first joint and a second joint on both sides.
[0013] In the aforementioned assembled trash can, the number of side panels is even, with a first joint on both sides of one side panel and a second joint on both sides of the two adjacent side panels.
[0014] This modular trash can has a flexible shape, and can be triangular, square, rectangular, racetrack-shaped, round, oval, etc. The shape of this modular trash can can be flexibly adjusted according to needs, as long as the desired shape of the can can be formed by the enclosing of at least two side panels.
[0015] The design of having a first joint and a second joint on both sides of each side panel makes it easier and faster to connect the side panels. Under certain working conditions, even if one or two side panels are missing, the remaining side panels can still be assembled to form a bin. At the same time, during transportation, several side panels can be assembled to form a storage space, and then the base, upper frame, bin lid assembly and other side panels can be placed in this storage space, thereby reducing the space occupied by this assembled trash can during transportation or storage.
[0016] As an alternative, both sides of each side panel can be either entirely set as the first joint or entirely set as the second joint, which facilitates production.
[0017] In the above-mentioned assembled trash can, a connecting cavity is formed in the first connecting part, and an elongated connecting port communicating with the connecting cavity is provided on the first connecting part. The length direction of the connecting port is parallel to the length direction of the first connecting part. The second connecting part includes a connecting plate and a limiting part. The connecting plate can extend into the connecting cavity through the connecting port. The width D1 of the limiting part is greater than the width D2 of the connecting port.
[0018] The design that the width of the limiting part is greater than the width of the connection port can prevent the limiting part of the second joint from coming out of the joint cavity of the first joint, thereby realizing the horizontal connection between the first joint and the second joint.
[0019] In the aforementioned assembled trash can, the outer wall of the limiting part abuts against or is less than 3mm away from the inner wall of the engaging cavity.
[0020] When the outer wall of the limiting part directly abuts against the inner wall of the connecting cavity, the connection between the first connecting part and the second connecting part is tighter, and the overall rigidity and firmness are better. When there is a gap of less than 3mm between the outer wall of the limiting part and the inner wall of the connecting cavity, even if the first connecting part and the second connecting part are inserted and assembled, it can be ensured that the connection between the limiting part and the connecting cavity is not too loose and has a certain elastic space. Preferably, the distance between the outer wall of the limiting part and the inner wall of the connecting cavity is controlled at about 1mm.
[0021] In the aforementioned assembled trash can, both the first and second joints are located on the inner or outer side of their respective side panels. The joint cavity is rectangular and is formed by rectangular outer joint segments one, two, three, and four connected vertically in sequence. A connection is formed between rectangular outer joint segments one and four. The limiting part can be formed by four rectangular inner joint segments connected vertically in sequence, with the width of each rectangular inner joint segment being smaller than the corresponding rectangular outer joint segment. Alternatively, the limiting part can be formed by three rectangular inner joint segments connected vertically in sequence, with the last rectangular inner joint segment abutting against the inner sidewall of rectangular outer joint segment four.
[0022] In the above-mentioned assembled trash can, the first joint and the second joint are both located on the inner or outer side of the side plate. The joint cavity is arc-shaped and is formed by arc-shaped joint section one and arc-shaped joint section two. A connection port for the connecting plate to pass through is formed between arc-shaped joint section one and arc-shaped joint section two. The limiting part is arc-shaped and can abut against the inner wall of arc-shaped joint section two.
[0023] The aforementioned joint cavity is arc-shaped, but can be circular, elliptical, racetrack-shaped, semi-circular, etc.
[0024] In one of the above-mentioned assembled trash cans, the first and second joints are both located on the inner or outer side of the side plate. The joint cavity is triangular and is formed by three outer triangular joint segments. The limiting part is formed by two sequentially connected inner triangular joint segments, and the last inner triangular joint segment can abut against the inner sidewall of the outer triangular joint segment three. Alternatively, the limiting part is triangular and is formed by three sequentially connected inner triangular joint segments, and the shape of the limiting part matches the shape of the joint cavity.
[0025] In the aforementioned assembled trash can, both the first joint and the second joint partially protrude from the inner side of the side plate and partially protrude from the outer side of the side plate. The connection port is located on the side of the first joint away from the side plate, and the joint cavity of the first joint is rectangular, triangular, or arc-shaped.
[0026] The arc shape in the aforementioned joint cavity can be circular, elliptical, semi-circular, or other shapes, as long as it allows the limiting part to be inserted into the joint cavity, thereby enabling the first joint and the second joint to be positioned horizontally.
[0027] In the aforementioned assembled trash can, both the first joint and the second joint extend from the upper part of the side plate to the lower part of the side plate.
[0028] In the aforementioned assembled trash can, both the first joint and the second joint are elongated. There are at least two first joints, which are vertically spaced along the side plate. The second joint is configured to cooperate with the first joint.
[0029] In the aforementioned assembled trash can, both the first joint and the second joint are formed by bending the edge of the side plate several times.
[0030] The first and second joints are formed by directly bending the side plates, which is convenient and quick to produce. The side plates in this assembled trash can are generally made of metal or other rigid materials such as plastic steel or hard plastic. The materials of the first and second joints are the same as those of the side plates, which can improve the firmness and stability of the first and second joints after molding, and help to improve the service life of this assembled trash can.
[0031] In the aforementioned assembled trash can, there is a certain gap between the upper ends of the first joint and the second joint and the upper edge of the side plate, and there is a certain gap between the lower ends of the first joint and the second joint and the lower edge of the side plate.
[0032] The aforementioned gap design prevents interference between the side panel and the corresponding base or upper frame when the side panel is inserted into the lower or upper slot, which helps improve the portability and stability of this assembled trash can during connection.
[0033] In the above-mentioned assembled trash can, the upper end of the side plate is bent downward to form an upper folding part, and a number of upper positioning buckles are arranged circumferentially along the inner edge of the upper slot. The upper edge of the upper positioning buckle can abut against the lower edge of the upper folding part.
[0034] Alternatively, the lower end of the side plate may be bent upward to form a lower folded part, and a number of lower positioning buckles are arranged circumferentially along the inner edge of the lower slot, and the lower edge of the lower positioning buckle may abut against the upper edge of the lower folded part.
[0035] Alternatively, the upper end of the side plate is bent downward to form an upper folded part, and the lower end is bent upward to form a lower folded part. Several upper positioning buckles are arranged circumferentially along the inner edge of the upper slot, and the upper edge of the upper positioning buckle can abut against the lower edge of the upper folded part. Several lower positioning buckles are arranged circumferentially along the inner edge of the lower slot, and the lower edge of the lower positioning buckle can abut against the upper edge of the lower folded part.
[0036] The design of the upper folding part increases the structural strength of the upper side plate, and the design of the lower folding part increases the structural strength of the lower side plate. Furthermore, the upper folding part, in conjunction with the upper positioning buckle, can also position the upper side plate, preventing the upper folding part from easily coming out of the upper slot. Similarly, the lower folding part, in conjunction with the lower positioning buckle, can prevent the lower folding part from easily coming out of the lower slot, which helps to improve the stability of this assembled trash can after connection.
[0037] In the aforementioned assembled trash can, the base is provided with four lower limit slots, and the lower ends of the first joint and the second joint can be inserted into the lower limit slots; the lower side of the upper frame is provided with four upper limit slots, and the upper ends of the first joint and the second joint can be inserted into the upper limit slots.
[0038] The design of the lower and upper limit grooves can further limit the first and second joints after insertion, preventing the assembled side plate from shifting relative to the base or upper frame in the horizontal direction, which helps to further improve the stability of this assembled trash can after connection.
[0039] In the aforementioned assembled trash can, the lid assembly includes a mounting base, a lid plate, and a connector. The mounting base is detachably connected to the upper frame, and a disposal opening for disposing of trash is provided in the middle of the mounting base. The lid plate is rotatably connected to the mounting base via the connector, and the lid plate can cover the disposal opening.
[0040] The design of the aforementioned cover, mounting base, and connectors allows the dispensing port to be covered when not in use, resulting in greater hygiene and cleanliness.
[0041] In the aforementioned assembled trash can, the cover includes a first cover and a second cover. The first cover is rotatably connected to the rear of the mounting base via a connector, and the second cover is rotatably connected to the front of the mounting base via a connector. When the first and second covers are closed, they can cover the disposal opening. The first and second covers can be flipped outwards to open the disposal opening.
[0042] In the aforementioned assembled trash can, a drive chamber is provided inside the mounting base, and a connection hole is provided at the rear of the upper side of the mounting base. The connector includes a mounting part, a connecting part, and a hinge part connected in sequence. The mounting part is fixedly connected to the rear of the cover plate. The connecting part is arc-shaped and passes through the connection hole. The hinge part is located inside the drive chamber, and the left and right ends of the hinge part are hinged to the mounting base. A drive motor is provided inside the drive chamber. The drive motor can drive the connector to rotate around the hinge point, thereby causing the cover plate to open or close.
[0043] The aforementioned drive motor design enables the automatic opening and closing of the cover. By setting sensing elements on the base or mounting seat, the cover can be automatically opened when a person or hand approaches the trash can lid. The arc-shaped connection part design reduces the clearance space required when the cover rotates, thus allowing the width of the connection hole to be designed to be narrower. This prevents trash from entering the mounting seat through the connection hole, affecting the normal opening and closing of the cover, and improving stability.
[0044] In the aforementioned assembled trash can, an annular pressure ring is included. The lower part of the inner side of the upper frame is formed with an inwardly protruding ring. The pressure ring can be placed on the upper side of the protruding ring. An annular positioning groove is provided on the outer edge of the lower side of the mounting base. The upper end of the upper frame can be fully or partially inserted into the positioning groove. The lower side of the mounting base can abut against the upper side of the pressure ring.
[0045] The aforementioned pressure ring, together with the convex ring of the upper frame, can fix and position the upper edge of the garbage bag, preventing the garbage bag from falling into the garbage can. The structure is simple, easy to install, and more tidy and stable during use.
[0046] Compared with the prior art, the technical effects of this utility model are as follows:
[0047] In this invention, the second joint portion on the adjacent side plates is inserted into the first joint portion to achieve the connection between the two adjacent side plates. This eliminates the need for fixing clips or other accessories, effectively avoiding problems such as the side plates being unable to connect due to the loss of the fixing clips. At the same time, eliminating the fixing clips also avoids problems such as the weakening of the connection between the side plates due to factors such as the fixing clips becoming brittle, breaking, or deforming. The first joint portion is directly connected to the second joint portion of the adjacent side plate, making the structure simpler, the assembly more convenient, and the assembled firmness and stability higher.

[0061] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.
[0062] This modular trash can includes a base 1, an upper frame 2, a lid assembly 3, and at least two side plates 4 connected in sequence. The lower ends of the side plates 4 are inserted and fixed into the lower slots 11 of the base 1, and the upper ends are inserted and fixed into the upper slots 21 of the upper frame 2. The lid assembly 3 is connected to the upper frame 2. A first joint 5 and a second joint 6 are respectively provided at the joint of two adjacent side plates 4. The second joint 6 can be inserted vertically into the first joint 5, and the first joint 5 can cooperate with the second joint 6 to achieve horizontal fixation. In this modular trash can, the second joint 6 on adjacent side panels 4 is inserted into the first joint 5 to connect the two adjacent side panels 4. No fixing clips or other accessories are needed for fixing, which can effectively avoid problems such as the side panels 4 not being able to be connected due to the loss of fixing clips. At the same time, eliminating the fixing clips can also avoid problems such as the connection between the side panels 4 becoming weak due to factors such as the fixing clips becoming brittle, breaking, or deforming. The first joint 5 is directly connected to the second joint 6 of the adjacent side panel 4, which makes the structure simpler, the assembly more convenient, and the strength and stability after assembly are higher.
[0063] Furthermore, each side panel 4 is provided with a first joint 5 and a second joint 6 on both sides. The shape of this assembled trash can is relatively flexible, and it can be triangular, square, rectangular, racetrack-shaped, circular, elliptical, etc. The shape of this assembled trash can can be flexibly adjusted as needed, as long as the required bin shape can be formed by enclosing at least two side panels 4. The design of providing a first joint 5 and a second joint 6 on both sides of each side panel 4 makes the connection between the side panels 4 more convenient and quick. Under certain working conditions, even if one or two side panels 4 are missing, the remaining side panels 4 can still be enclosed to form a bin. At the same time, during transportation, several side panels 4 can be enclosed to form a accommodating space, and then the base 1, upper frame 2, bin lid assembly 3 and other side panels 4 can be placed in this accommodating space, thereby reducing the space occupied by this assembled trash can during transportation or storage. As another option, the number of side panels 4 is even, with a first joint 5 provided on both sides of one side panel 4, and a second joint 6 provided on both sides of the two adjacent side panels 4. Both sides of each side plate 4 are either entirely set as first joints 5 or entirely set as second joints 6, which facilitates production.
[0064] like Figure 3 , Figure 8 and Figure 9As shown, a joint cavity 51 is formed within the first joint portion 5. An elongated connecting port 52 communicating with the joint cavity 51 is provided on the first joint portion 5. The length direction of the connecting port 52 is parallel to the length direction of the first joint portion 5. The second joint portion 6 includes a connecting plate 62 and a limiting portion 61. The connecting plate 62 can extend into the joint cavity 51 through the connecting port 52. The width D1 of the limiting portion 61 is greater than the width D2 of the connecting port 52. This design, where the width of the limiting portion 61 is greater than the width of the connecting port 52, prevents the limiting portion 61 of the second joint portion 6 from dislodging from the joint cavity 51 of the first joint portion 5, thereby achieving a horizontal connection between the first joint portion 5 and the second joint portion 6.
[0065] Furthermore, the outer wall of the limiting part 61 abuts against or is less than 3mm away from the inner wall of the connecting cavity 51. When the outer wall of the limiting part 61 directly abuts against the inner wall of the connecting cavity 51, the connection between the first connecting part 5 and the second connecting part 6 is tighter, and the overall rigidity and firmness are better. When there is a gap of less than 3mm between the outer wall of the limiting part 61 and the inner wall of the connecting cavity 51, even if the first connecting part 5 and the second connecting part 6 are inserted and assembled, it can be ensured that the connection between the limiting part 61 and the connecting cavity 51 is not too loose and has a certain elastic space. Preferably, the distance between the outer wall of the limiting part 61 and the inner wall of the connecting cavity 51 is controlled to be about 1mm.
[0066] like Figure 3 As shown, the first joint 5 and the second joint 6 are both located on the inner or outer side of the side plate 4. The joint cavity 51 is rectangular and is formed by rectangular outer joint section one 5111, rectangular outer joint section two 5112, rectangular outer joint section three 5113 and rectangular outer joint section four 5114 connected vertically in sequence. A connection port 52 is formed between rectangular outer joint section one 5111 and rectangular outer joint section four 5114. The limiting part 61 can be formed by four rectangular inner joint sections 611 connected vertically in sequence, and the width of each rectangular inner joint section 611 is smaller than the corresponding rectangular outer joint section; or the limiting part 61 can be formed by three rectangular inner joint sections 611 connected vertically in sequence, and the last rectangular inner joint section 611 can abut against the inner sidewall of rectangular outer joint section four 5114.
[0067] like Figure 8 As shown, both the first joint 5 and the second joint 6 are located on the inner or outer side of their respective side plates 4. The joint cavity 51 is arc-shaped and is formed by an arc-shaped joint segment 1 5121 and an arc-shaped joint segment 2 5122. A connection port 52 for the connecting plate 62 to pass through is formed between the arc-shaped joint segment 1 5121 and the arc-shaped joint segment 2 5122. The limiting part 61 is arc-shaped and can abut against the inner wall of the arc-shaped joint segment 2 5122. The aforementioned joint cavity 51 is arc-shaped and can be circular, elliptical, racetrack-shaped, semi-circular, etc.
[0068] like Figure 9 As shown, the first joint 5 and the second joint 6 are both located on the inner or outer side of the side plate 4. The joint cavity 51 is triangular and is formed by the first triangular outer joint segment 5131, the second triangular outer joint segment 5132, and the third triangular outer joint segment 5133. The limiting part 61 is formed by two triangular inner joint segments 613 connected in sequence. The last triangular inner joint segment 613 can abut against the inner sidewall of the third triangular outer joint segment 5133. Alternatively, the limiting part 61 is triangular and is formed by three triangular inner joint segments 613 connected in sequence. The shape of the limiting part 61 matches the shape of the joint cavity 51.
[0069] like Figure 10 As shown, both the first joint 5 and the second joint 6 protrude partially from the inner side of the side plate 4 and partially from the outer side of the side plate 4. The connection port 52 is located on the side of the first joint 5 away from the side plate 4. The joint cavity 51 of the first joint 5 is rectangular, triangular, or arc-shaped. The arc shape in the joint cavity 51 can be circular, elliptical, semi-circular, etc., as long as the limiting part 61 can be inserted into the joint cavity 51, thereby enabling the first joint 5 and the second joint 6 to be positioned horizontally.
[0070] like Figure 2 As shown, both the first joint 5 and the second joint 6 extend from the upper part of the side plate 4 to the lower part of the side plate 4. Alternatively, as... Figure 7 As shown, both the first joint 5 and the second joint 6 are elongated strips. There are at least two first joints 5, which are arranged at vertical intervals along the side plate 4. The second joint 6 is arranged in conjunction with the first joint 5.
[0071] like Figure 3 , Figure 8 and Figure 9 As shown, both the first joint 5 and the second joint 6 are formed by bending the edge of the side plate 4 several times. The first joint 5 and the second joint 6 are formed by directly bending the side plate 4, which is convenient and quick to produce. The side plate 4 in this assembled trash can is generally made of metal or other rigid materials such as plastic steel or hard plastic. The fact that the materials of the first joint 5 and the second joint 6 are the same as those of the side plate 4 improves the firmness and stability of the first joint 5 and the second joint 6 after molding, thus extending the service life of this assembled trash can.
[0072] like Figure 4 and Figure 7As shown, there is a certain gap between the upper ends of the first joint 5 and the second joint 6 and the upper edge of the side plate 4, and a certain gap between the lower ends of the first joint 5 and the second joint 6 and the lower edge of the side plate 4. The design of the above gaps can avoid interference between the side plate 4 and the corresponding base 1 or upper frame 2 when it is inserted into the lower slot 11 or the upper slot 21, which is beneficial to improving the portability and stability of this assembled trash can when connected.
[0073] like Figure 2 , Figure 4 and Figure 7 As shown, the upper end of the side plate 4 is bent downward to form an upper folding part 41. Several upper positioning buckles 211 are arranged circumferentially along the inner edge of the upper slot 21. The upper edge of the upper positioning buckle 211 can abut against the lower edge of the upper folding part 41.
[0074] Alternatively, the lower end of the side plate 4 can be bent upward to form a lower folding part 42. Several lower positioning buckles 111 are arranged circumferentially along the inner edge of the lower slot 11. The lower edge of the lower positioning buckle 111 can abut against the upper edge of the lower folding part 42.
[0075] Alternatively, the upper end of the side plate 4 can be bent downward to form an upper folding part 41, and the lower end can be bent upward to form a lower folding part 42. Several upper positioning buckles 211 are arranged circumferentially along the inner edge of the upper slot 21, and the upper edge of the upper positioning buckle 211 can abut against the lower edge of the upper folding part 41. Several lower positioning buckles 111 are arranged circumferentially along the inner edge of the lower slot 11, and the lower edge of the lower positioning buckle 111 can abut against the upper edge of the lower folding part 42.
[0076] The design of the upper folding part 41 increases the structural strength of the upper side of the side plate 4, and the design of the lower folding part 42 increases the structural strength of the lower side of the side plate 4. Furthermore, the upper folding part 41, in conjunction with the upper positioning buckle 211, can also achieve positioning of the upper part of the side plate 4, preventing the upper folding part 41 from easily coming out of the upper slot 21. Similarly, the lower folding part 42, in conjunction with the lower positioning buckle 111, can prevent the lower folding part 42 from easily coming out of the lower slot 11, which is beneficial to improving the stability of this assembled trash can after connection.
[0077] Furthermore, the base 1 is provided with four lower limiting grooves 12, into which the lower ends of the first joint 5 and the second joint 6 can be inserted; the lower side of the upper frame 2 is provided with four upper limiting grooves 22, into which the upper ends of the first joint 5 and the second joint 6 can be inserted. The design of the lower limiting grooves 12 and the upper limiting grooves 22 can further limit the first joint 5 and the second joint 6 after insertion, preventing the assembled side plate 4 from shifting relative to the base 1 or the upper frame 2 in the horizontal direction, which is beneficial to further improving the stability of this assembled trash can after connection.
[0078] like Figure 1-6As shown, the bin lid assembly 3 includes a mounting base 31, a cover plate 32, and a connector 33. The mounting base 31 is detachably connected to the upper frame 2. A disposal opening 311 for disposing of waste is provided in the middle of the mounting base 31. The cover plate 32 is rotatably connected to the mounting base 31 via the connector 33, and the cover plate 32 can cover the disposal opening 311. The design of the cover plate 32, mounting base 31, and connector 33 allows the disposal opening 311 to be covered by the cover plate 32 when not in use, resulting in greater hygiene and cleanliness.
[0079] like Figure 11 and 12 As shown, the cover 32 includes a first cover 321 and a second cover 322. The first cover 321 is rotatably connected to the rear of the mounting base 31 via a connector 33, and the second cover 322 is rotatably connected to the front of the mounting base 31 via a connector 33. When the first cover 321 and the second cover 322 are closed, they can cover the disposal opening 311. The first cover 321 and the second cover 322 can be flipped outward to open the disposal opening 311. The design of the two covers 32 can reduce the overall height of the cover 32 when it is open and increase the angle of waste disposal, thus avoiding interference with normal waste disposal when the cover 32 is open.
[0080] Furthermore, a drive chamber 312 is provided inside the mounting base 31, and a connection hole 313 is provided at the rear of the upper side of the mounting base 31. The connector 33 includes a mounting part 331, a connecting part 332, and a hinge part 333 connected in sequence. The mounting part 331 is fixedly connected to the rear of the cover plate 32. The connecting part 332 is arc-shaped and passes through the connection hole 313. The hinge part 333 is located inside the drive chamber 312. The left and right ends of the hinge part 333 are hinged to the mounting base 31. A drive motor 34 is provided inside the drive chamber 312. The drive motor 34 can drive the connector 33 to rotate around the hinge, thereby driving the cover plate 32 to open or close. The design of the aforementioned drive motor 34 enables the automatic opening and closing of the cover 32. By setting a sensing element on the base 1 or mounting base 31, the cover 32 can be automatically opened when a person or hand approaches the trash can lid. The design of the arc-shaped connecting part 332 reduces the clearance space required when the cover 32 rotates, thereby allowing the width of the connecting hole 313 to be designed to be narrower. This prevents trash from entering the mounting base 31 through the connecting hole 313, affecting the normal opening and closing of the cover 32, and improving stability.
[0081] Furthermore, the modular trash can includes an annular pressure ring 7. The lower inner side of the upper frame 2 has an inwardly protruding ring 23. The pressure ring 7 can be placed on the upper side of the protruding ring 23. An annular positioning groove 314 is provided on the outer edge of the lower side of the mounting base 31. The upper end of the upper frame 2 can extend entirely or partially into the positioning groove 314, and the lower side of the mounting base 31 can abut against the upper side of the pressure ring 7. The pressure ring 7, in conjunction with the protruding ring 23 of the upper frame 2, can fix and position the upper edge of the trash bag, preventing the trash bag from falling into the trash can. The structure is simple, easy to install, and more tidy and stable during use.
[0082] The above embodiments are merely preferred embodiments of the present utility model and are not intended to limit the scope of protection of the present utility model. Therefore, all equivalent changes made to the structure, shape, and principle of the present utility model should be covered within the scope of protection defined by the claims of the present utility model.
