Description

Technical Field

[0001] This technical solution relates to the field of everyday household items, specifically a type of trash can. Background Technology

[0002] As a common household item, trash cans, especially double-layered ones, offer certain advantages in use. For example, Chinese Patent CN201920025328.7 discloses a trash can that includes a base, an inner bin inserted into the base, an outer bin fitted around the inner bin, and a trash bag placed inside the inner bin. The upper edge of the trash bag is pressed down and covered by the outer bin, resulting in an aesthetically pleasing design and preventing the trash bag from falling off easily.

[0003] However, it still has some shortcomings. The outer bin simply fits over the inner bin, relying on its own weight to hold the garbage bag in place. There's no locking mechanism between the outer and inner bins. When moving or lifting the entire bin, both hands must be used: one hand holding the outer bin, and the other supporting the base of the inner bin to prevent slippage. This operation is cumbersome and laborious. A slight oversight can cause the outer and inner bins to separate, leading to the inner bin falling off, causing damage, and even spilling garbage from the inner bin and contaminating the room. Furthermore, during transportation, the outer and inner bins are prone to collisions, friction, and compression due to bumps, resulting in structural deformation and damage, increasing transportation losses and logistics costs. Utility Model Content

[0004] The purpose of this technical solution is to provide a trash can that, by rotating a limiting component within the installation opening, causes the limiting part to abut against the lower end of the anti-detachment part, thereby restricting the relative movement of the outer and inner bins and improving the problem of inconvenient movement and handling caused by the easy separation of the outer and inner bins.

[0005] The purpose of this technical solution is achieved as follows:

[0006] A trash can includes:

[0007] Inner tub;

[0008] The outer tub can be installed over the outside of the inner tub from top to bottom;

[0009] At least one limiting device is installed on the outer tub and movably abuts against the inner tub to limit the relative movement of the outer tub and the inner tub;

[0010] The limiting device includes:

[0012] The anti-detachment part is formed on the inner barrel;

[0013] The limiting part moves to abut against the lower end of the anti-detachment part, thereby preventing the outer tub from detaching from the inner tub.

[0014] Preferably, the limiting device further includes;

[0015] An elastic element is installed between the outer tub and the limiting element to give the limiting part a tendency to move closer to the inside of the outer tub, so that the limiting part abuts against the lower end of the anti-detachment part.

[0016] Preferably, a card interface is provided on the side wall of the outer barrel, a mounting plate is engaged with the card interface, the mounting plate has the mounting opening, and the limiting member is installed on the mounting plate;

[0017] The inner wall of the card interface is provided with a limiting protrusion, and both ends of the mounting plate are provided with a snap-fit ​​part; the snap-fit ​​part passes through the card interface and is placed inside the outer barrel, and the snap-fit ​​part abuts against the edge of the card interface to restrict the mounting plate from moving outward of the outer barrel;

[0018] The limiting protrusion abuts against the edge of the mounting plate to restrict the mounting plate from moving toward the inside of the outer barrel.

[0019] Preferably, the lower end of the limiting part is provided with a guide surface;

[0020] When the outer tub covers the outside of the inner tub from top to bottom, the anti-detachment part slides on the guide surface, causing the limiting part to move away from the inside of the outer tub.

[0021] and / or

[0022] The upper end of the anti-detachment part is provided with a guide surface two; when the outer tub covers the outside of the inner tub from top to bottom, the guide surface two slides on the lower end of the limiting part, causing the limiting part to move away from the inside of the outer tub.

[0023] Preferably, the limiting member is provided with a rotating operating part, and by pulling the rotating operating part, the limiting part can be disengaged from the underside of the anti-detachment part.

[0024] Preferably, the anti-detachment part is a raised edge formed on the outer side of the upper end of the inner barrel, and the lower end of the raised edge is in movable contact with the upper end of the limiting part;

[0025] Alternatively, the anti-detachment part is an anti-detachment groove formed on the outer wall of the inner barrel, and the upper inner wall of the anti-detachment groove is in movable contact with the upper end of the limiting part.

[0026] Preferably, the side end of the limiting member is provided with a limiting rotation part one, which abuts against the edge of the mounting opening when the limiting member rotates toward the outside of the outer barrel;

[0027] A second limiting rotation part is provided on the inner side wall of the installation port. When the limiting member rotates toward the inside of the outer barrel, the second limiting rotation part abuts against the limiting member.

[0028] Preferably, the mounting port is provided with a hinge portion on the inner edge of the outer barrel, the hinge portion is provided with a hinge hole and a limiting groove one, the side wall of the limiting member is provided with a hinge shaft and a limiting groove two, the elastic member is a torsion spring, the hinge shaft is rotatably placed in the hinge hole, the middle part of the torsion spring is sleeved on the hinge shaft, and the two ends of the torsion spring are respectively placed in the limiting groove one and the limiting groove two.

[0029] Preferably, the upper half of the limiting member is hinged to the mounting opening of the outer barrel, the middle part of the limiting member is provided with a limiting part, and the lower half of the limiting member is provided with a rotating operating part protruding from the outer side wall of the outer barrel.

[0030] Preferably, the lower end of the inner tub is provided with a base, and the side end of the base has a boss, which abuts against the lower end of the outer tub to limit the range of movement of the outer tub outside the inner tub.

[0031] The key and beneficial technical effects of this technical solution compared to existing technologies are:

[0032] 1. This technical solution uses a limiting component that rotates on the outer bin, causing the limiting part to abut against the lower end of the anti-detachment part of the inner bin, thus fixing the position between the outer and inner bins, preventing the inner and outer bins from separating, facilitating the overall movement of the garbage bin, and eliminating the need to deliberately support the inner and outer bins during handling and transportation, making operation more labor-saving. At the same time, it reduces garbage spillage and component collisions caused by separation, improving ease of use and overall stability.

[0033] 2. This technical solution uses the elastic deformation of the elastic element to realize the rotation of the limiting element, thereby causing the limiting part to rotate towards the inside of the outer barrel, so that the limiting part abuts against the lower end of the anti-detachment part, ensuring that the limiting device can be in the limiting and locking state.

[0034] 3. This technical solution uses the rotating operating part to pull the limiting part, causing the limiting part to rotate and separating the limiting part from the anti-detachment part, thereby separating the outer bin from the inner bin and facilitating the replacement of garbage bags.

[0035] 4. This technical solution uses guide surface one and guide surface two to allow the outer bucket to cover the outside of the inner bucket from top to bottom, without the need for manual rotation of the limiting parts, making it convenient to install the outer bucket and quick and easy to operate.

[0036] 5. This technical solution uses limiting components and elastic components to install on the mounting plate, forming a module, which is then snapped onto the outer barrel. This design facilitates modular production and assembly of the limiting and elastic components, and also makes it convenient for overall module replacement and maintenance. Furthermore, the mounting plate and outer barrel are produced separately, making it easier to form the hinge part on the mounting plate, which is more conducive to production and demolding. In addition, the mounting plate can also serve a decorative purpose by changing its color. Attached Figure Description

[0053] The specific implementation of this technical solution will be further described in detail below with reference to the accompanying drawings. See also Figures 1-9 .

[0054] Example 1:

[0055] Combination Figure 1 and Figure 2 A type of trash can, comprising:

[0056] The inner bucket 1 has an opening 12 at its upper end, which is used to allow garbage to be put into the inner bucket 1.

[0057] The outer bucket 2 can be installed over the outer bucket 1 from top to bottom to prevent the inner bucket 1 and garbage bag from being exposed. The lower end of the outer bucket 2 is provided with an opening 23 for the inner bucket 1 to be inserted into the outer bucket 2.

[0058] At least one limiting device 3 is installed on the outer bucket 2 and movably abuts against the inner bucket 1 to limit the relative movement of the outer bucket 2 and the inner bucket 1, that is, to limit the range of movement of the outer bucket 2 outside the inner bucket 1, to prevent the outer bucket 2 from separating from the top of the inner bucket 1, and to ensure that the inner bucket 1 and the outer bucket 2 are a whole and can be moved or lifted easily. In this design, a limiting device 3 is provided on each of the two opposite side walls of the outer bucket 2.

[0059] Combination Figures 3-7 The limiting device 3 includes:

[0060] The limiting member 31 is hinged in the mounting opening 41 of the outer barrel 2, and the limiting member 31 can rotate in the mounting opening 41 and extend to the outside of the outer barrel 2. The limiting member 31 has a limiting part 33 on its end face near the inside of the outer barrel 2.

[0061] The anti-detachment part 11 is formed on the inner tub 1, and the limiting part 33 moves against the lower end of the anti-detachment part 11 to restrict the movement of the outer tub 2 outside the inner tub 1 and prevent the outer tub 2 from detaching from the inner tub 1. The limiting part 31 rotates towards the inside of the outer tub 2 under its own weight, so that the limiting part 33 is placed below the anti-detachment part 11, so that when the outer tub 2 detaches from the inner tub 1 from bottom to top, the limiting part 33 can abut against the lower end face of the anti-detachment part 11, thereby preventing the separation between the inner tub 1 and the outer tub 2.

[0062] The limiting device 3 also includes an elastic member 32, which is installed between the outer tub 2 and the limiting member 31, so that the limiting part 33 has a tendency to move closer to the inside of the outer tub 2, so that the limiting part 33 abuts against the anti-detachment part 11, and the elastic deformation of the elastic member 32 ensures that the limiting part 33 can be placed below the anti-detachment part 11.

[0063] By utilizing the weight of the limiting member 31 and / or the elastic deformation of the elastic member 32, the limiting member 31 rotates towards the inside of the outer tub 2, i.e., towards the inner tub 1. This causes the limiting part 33 to abut against the lower end of the anti-detachment part 11, thereby preventing the outer tub 2 from detaching from the outside of the inner tub 1 from bottom to top, and also preventing the inner tub 1 from detaching from the lower end of the outer tub 2. This allows the inner tub 1 to move along with the outer tub 2 when it is lifted or moved, making it easy to move without the user having to hold the outer tub with one hand and drag the bottom of the inner tub with the other. Furthermore, since the bottom of the inner tub (or the base of the inner tub) is generally placed on the ground, the limiting device 3 also prevents the hand holding the bottom of the inner tub from contacting the ground and getting dirty.

[0064] To facilitate injection molding production and demolding, combined with Figures 3-7 The outer barrel 2 has a snap-fit ​​interface 21 on its side wall. The snap-fit ​​interface 21 is snapped with an installation plate 4. The installation plate 4 is equipped with a limiting component 31 and an elastic component 32. The installation plate 4 is then snapped onto the outer barrel 2. The modular assembly is then performed on the installation plate 4. This not only facilitates production but also makes it easier for replacement and maintenance in the future.

[0065] like Figure 3 and Figure 7 The mounting plate 4 has a mounting opening 41 in the middle, which connects the inside and outside of the outer barrel 2. The limiting member 31 and the elastic member 32 are installed in the mounting opening 41 on the mounting plate 4. The inner side wall of the locking interface 21 is provided with a limiting protrusion 22. Both the upper and lower ends of the mounting plate 4 are provided with locking parts 42. The locking parts 42 pass through the locking interface 21 and are placed inside the outer barrel 2 by their own elastic deformation. The locking parts 42 abut against the edge of the locking interface 21 to restrict the mounting plate 4 from moving outward from the outer barrel 2. The limiting protrusion 22 abuts against the edge of the mounting plate 4, specifically the edge of the side surface of the mounting plate 4 with the locking part 42. The limiting protrusion 22 is used to restrict the mounting plate 4 from moving inward from the outer barrel 2. That is, the mounting plate 4 is fixed in position on the locking interface 21 by the limiting protrusion 22 and the locking part 42, thus achieving the locking and fixing of the mounting plate 4.

[0066] Combination Figure 3 and Figure 6The lower end of the limiting part 33 is provided with a guide surface 331; when the outer tub 2 covers the outside of the inner tub 1 from top to bottom, the anti-detachment part 11 slides on the guide surface 331, causing the limiting part 33 to move away from the inside of the outer tub 2, thereby realizing that the outer tub 2 covers the outside of the inner tub 1, and realizing that the anti-detachment part 11 moves to the top of the limiting part 33, thereby realizing that the limiting part 33 abuts against the lower end of the anti-detachment part 11 to ensure the position lock between the outer tub 2 and the inner tub 1;

[0067] When the outer bucket 2 is installed on the inner bucket 1, the design of the guide surface 331 enables the limiting part 33 to move away from the inside of the outer bucket 2. The user does not need to manually drive the limiting part 31 to rotate so that the limiting part 33 moves away from the inside of the outer bucket 2, making it convenient for the outer bucket 2 to be fitted onto the inner bucket 1 and easy to operate.

[0068] In order to further improve the sliding of the anti-detachment part 11 on the guide surface 331, a guide surface 111 is provided on the upper end of the anti-detachment part 11. The guide surface 111 is an arc-shaped surface. The guide surface 111 can slide on the guide surface 331 or the lower end surface of the limiting part 33, thereby driving the limiting part 33 away from the interior of the outer barrel 2.

[0069] The limiting member 31 is provided with a rotating operating part 34. The rotating operating part 34 is either a handle protruding from the end face of the limiting member 31 or a rotating operating groove opened on the limiting member 31. By pulling the rotating operating part 34, the elastic deformation of the elastic member 32 is overcome, so that the limiting member 31 rotates in the mounting opening 41, thereby realizing the separation of the limiting part 33 from the lower end of the anti-detachment part 11, thus realizing the separation between the inner bucket 1 and the outer bucket 2. That is, at this time, the outer bucket 2 can leave the inner bucket 1 from bottom to top, so as to replace the garbage bag in the inner bucket 1 or clean the inner bucket 1.

[0070] like Figure 3 and Figure 8 The anti-detachment part 11 is a raised edge formed on the outer side of the upper end of the inner barrel 1, that is, a raised edge is provided on the outer side of the opening 12. The lower end of the raised edge is in contact with the upper end of the limiting part 33. In addition, the limiting part 33 can press the garbage bag opening at the opening 12 against the lower end of the raised edge, thereby fixing the garbage bag.

[0071] Combination Figures 5-7The side end of the limiting member 31 is provided with a limiting rotation part 35. When the limiting member 31 rotates outward towards the outer tub 2, that is, when the limiting member 31 rotates away from the inner tub 1, the limiting rotation part 35 abuts against the edge of the mounting opening 41, thereby limiting the limiting member 31 away from the inner tub 1 and preventing the limiting member 31 from rotating too much. In addition, when the outer tub 2 needs to be separated from the inner tub 1, after rotating the limiting member 31, the limiting part 33 separates from the anti-detachment part 11. By pulling the limiting member 31 by hand to lift the outer tub 2, the limiting rotation part 35 abutting against the edge of the mounting opening 41 can also ensure that the connection between the limiting member 31 and the outer tub 2 will not break, making it convenient to lift the outer tub 2.

[0072] A second limiting rotation part 43 is provided on the inner wall of the installation port 41. When the limiting member 31 rotates toward the inside of the outer tub 2, the second limiting rotation part 43 abuts against the limiting member 31, preventing the limiting member 31 from rotating toward the direction closer to the inner tub 1 beyond the set angle under the elastic action of the elastic member 32. This ensures that the rotating operation part 34 can be operated normally by the user, and prevents the limiting member 31 from being completely rotated and placed inside the outer tub 2 after the outer tub 2 is removed from the inner tub 1. A third limiting rotation part 38 is provided on the limiting member 31, and the third limiting rotation part 38 abuts against the second limiting rotation part 43.

[0073] The mounting port 41 is located on the inner edge of the outer barrel 2 and has a hinge part 44. The hinge part 44 has a hinge hole 441 and a limiting groove 442. The two opposite side walls of the limiting member 31 have a hinge shaft 36 and a limiting groove 37. The elastic member 32 is a torsion spring. The hinge shaft 36 is rotatably placed in the hinge hole 441. The middle part of the torsion spring is sleeved on the hinge shaft 36, and the two ends of the torsion spring are respectively placed in the limiting groove 442 and the limiting groove 37. The torsion spring enables the limiting member 31 to rotate and makes the limiting part 33 abut against the lower end of the anti-detachment part 11.

[0074] In this technical solution, the upper half of the side wall of the limiting member 31 is hinged to the mounting port 41 of the outer barrel 2, that is, the hinge shaft 36 and the limiting groove 37 are set on the upper two side walls of the limiting member 31. The inner middle of the limiting member 31 is provided with a limiting part 33. The guide surface 331 is an inclined surface that is inclined towards the lower end of the limiting part 33. The lower half of the limiting member 31 is provided with a rotating operating part 34 that protrudes from the outer side wall of the outer barrel 2, and the lower end of the limiting member 31 is provided with a limiting rotating part 38.

[0075] Combination Figure 2 and Figure 8A base 5 is provided at the lower end of the inner tub 1. The side end of the base 5 has a boss 51. The boss 51 abuts against the lower end of the outer tub 2, that is, the opening 23 of the outer tub 2 abuts against the boss 51. This is used to limit the range of movement of the outer tub 2 outside the inner tub 1 and ensure that the outer tub 2 is installed stably. That is, the boss 51 restricts the downward movement of the outer tub 2 on the inner tub 1, and the limiting part 33 and the anti-detachment part 11 restrict the upward movement of the outer tub 2 on the inner tub 1, thereby fixing the position of the outer tub 2 on the inner tub 1.

[0076] The lower end of the inner tub 1 is inserted and connected to the base 5, and the bottom of the inner tub 1 is fixed to the base 5 by a snap fastener to prevent the inner tub 1 from detaching from the upper end of the base 5. The structure of the snap fastener is similar to that of the snap fastener part 42 and the snap fastener interface 21.

[0077] Combination Figure 2 and Figure 9 The outer barrel 2 is provided with a barrel lid device 6, which includes:

[0078] The mounting ring 61 is snapped onto the upper end of the outer tub 2;

[0079] The bucket lid 62 is hinged at its rear end to the rear end of the mounting ring 61, and a bucket lid torsion spring is provided at the hinge. The bucket lid torsion spring enables the bucket lid 62 to rotate away from the mounting ring 61. The front end of the bucket lid 62 is engaged with the front end of the mounting ring 61 by a buckle. The front end of the bucket lid 62 and the mounting ring 61 are engaged by a press-type buckle. The press-type buckle is referenced from the locking switch and locking limit in Chinese Patent CN202320091939.8.

[0080] like Figure 8 and Figure 9 The deodorizing device 7 is snapped onto the upper end of the lid 62, and the deodorizing device 7 has a storage cavity 71 for placing deodorizing agents, fragrances, or sachets that can remove or cover up the odor of the garbage can.

[0081] The deodorization device 7 includes:

[0082] The bottom box 72 has a snap fastener 722 at its lower end, which snaps into the snap hole 63 at the upper end of the lid 62.

[0083] The lid 73 is fastened to the upper end of the bottom box 72, and a storage cavity 71 is formed between the lid 73 and the bottom box 72. The lid 73 can be removed from the bottom box 72, so as to facilitate opening the storage cavity 71 to replace the deodorant.

[0084] Ventilation holes are provided on the lid 73 and / or the bottom box 72, which connect the storage cavity 71 to the outside world, so that the aromatherapy in the storage cavity 71 can release the fragrance gas.

[0085] Example 2:

[0086] The design scheme of this embodiment is basically the same as that of Embodiment 1, except that:

[0087] The elastic element 32 is a tension spring or an elastic rope (rubber band or rubber strip). One end of the elastic element 32 is connected to the lower side wall of the mounting port 41 or the lower end of the mounting plate 4 by a screw (or adhesive). The other end of the elastic element 32 is connected to the lower end of the limiting element 31 by a screw (or adhesive). The upper end of the limiting element 31 is hinged to the upper end of the mounting port 41. The elastic element 32 causes the lower end of the limiting element 31 to move toward the lower side wall of the mounting port 41, so that the limiting part 33 abuts against the anti-detachment part 11.

[0088] Example 3:

[0089] The design scheme of this embodiment is basically the same as that of Embodiment 1 or Embodiment 2, except that:

[0090] The lower half of the side wall of the limiting member 31 is hinged to the lower half of the mounting opening 41 of the outer tub 2. That is, the hinge shaft 36 and the limiting groove 37 are provided on the lower side walls of the limiting member 31. The inner middle of the limiting member 31 is provided with a limiting part 33. The guide surface 331 is an inclined surface that is inclined towards the lower end of the limiting part 33. The upper half of the limiting member 31 is provided with a rotating operating part 34 that protrudes from the outer side wall of the outer tub 2. The upper end of the limiting member 31 is provided with a limiting rotating part 38. The upper end of the limiting member 31 is rotated towards the inside of the outer tub 2 by the elastic member 32, so that the limiting part 33 is placed below the anti-detachment part 11. The limiting part 33 can abut against the lower end of the anti-detachment part 11 to restrict the relative movement of the outer tub 2 and the inner tub 1.

[0091] Example 4:

[0092] The design scheme of this embodiment is basically the same as that of Embodiment 1, except that:

[0093] The anti-detachment part 11 is an anti-detachment groove formed on the outer side wall of the inner barrel 1. The groove opening of the anti-detachment groove is set facing the outside of the inner barrel 1, that is, the groove opening of the anti-detachment groove faces the inner side wall of the outer barrel 2, so that the limiting part 33 can be inserted into the anti-detachment groove, and the upper inner wall of the anti-detachment groove moves and abuts against the upper end of the limiting part 33.
