Description

Technical Field

[0001] This invention relates to the field of trash can technology, and in particular to a wall-mounted trash can. Background Technology

[0002] Trash cans are common hygiene items in people's daily lives. There are many types of trash cans, and their sizes and opening mechanisms vary depending on the application. Currently, the main types of trash cans used indoors are floor-standing and wall-mounted. Floor-standing trash cans are mainly used in bedrooms, living rooms, and dining rooms, while wall-mounted trash cans are mainly used in kitchens.

[0003] To facilitate the collection of food waste, kitchen trash cans are usually designed to hang on the back of the cabinet. The trash can is hung directly on the cabinet door frame via hooks, allowing users to easily sweep food waste from the counter into the trash can.

[0004] Currently, the internal structure of wall-mounted kitchen trash cans on the market is complex and costly. The trash bag is directly placed around the top edge of the trash can. When users need to change the trash bag, they need to reach into the can to pick it up. However, the kitchen waste in the trash bag is a mixture of dry and wet waste, which can easily get users' hands dirty. To address this, a press-and-clamp bag mechanism has emerged on the market. However, the assembly structure is relatively complex, and users still need to reach into the can to disassemble the press-and-clamp bag mechanism, which is inconvenient. Summary of the Invention

[0005] This invention aims to address at least the technical problems existing in the prior art, namely that "when users change garbage bags, they need to reach into the bin to pick up the bag, and the kitchen waste in the garbage bag is a mixture of dry and wet waste, which easily soils the user's hands; and the pressing and clamping mechanism has a relatively complex assembly structure, requiring the user to reach into the bin to disassemble the pressing and clamping mechanism, which is inconvenient."

The use of "first" and "second" in the description is merely for distinguishing technical features and should not be construed as indicating or implying relative importance, or implicitly indicating the number of indicated technical features, or implicitly indicating the order of the indicated technical features.

[0047] In the description of this invention, unless otherwise explicitly defined, terms such as "set up," "install," and "connect" should be interpreted broadly, and those skilled in the art can reasonably determine the specific meaning of the above terms in this invention in conjunction with the specific content of the technical solution.

[0048] The following is for reference. Figures 1-16 A wall-mounted trash can is described according to an embodiment of the present invention.

[0049] like Figures 1-16 As shown, it includes a bin body 100, a garbage bag fixing part 300, and a linkage mechanism.

[0050] The garbage bag fixing part 300 is slidably disposed at the top of the bin body 100 to fix the garbage bag in the position inside the bin body 100.

[0051] A linkage mechanism is connected to one side of the bin body 100 and to the garbage bag fixing part 300, used to lift the garbage bag fixing part 300 above the bin body 100. The linkage mechanism includes a linkage rod 410 and a lifting drive part 420, with the linkage rod 410 connected to the lifting drive part 420, which is located below the garbage bag fixing part 300. When the linkage rod 410 rotates, the lifting drive part 420 moves with the linkage rod 410 to lift the bottom of the garbage bag fixing part 300.

[0052] Specifically, the linkage mechanism includes a linkage rod 410 and a lifting drive 420. The linkage rod 410 is located on the outside of the bin body 100, connected to the bin lid 200 on one side and to the lifting drive 420 on the other side. The lifting drive 420 is located on the inside of the bin body 100, below the garbage bag fixing part 300. The lifting drive 420 lifts the bottom of the garbage bag fixing part 300 upwards, raising the garbage bag fixing part 300 from above the bin body 100, facilitating direct replacement of the garbage bag without requiring the user to reach into the garbage bag for replacement, thus improving cleanliness and hygiene.

[0053] In some embodiments of the present invention, such as Figures 1-4 and Figures 9-11 As shown, the wall-mounted trash can includes a lid 200, which covers the top opening of the can body 100 to prevent the trash inside from coming into contact with the outside environment and rotting or attracting insects. A trash bag fixing part 300 is provided at the top of the can body 100. The trash bag fixing part 300 is vertically inserted into the can body 100 and slides in perpendicular to the end face of the can body 100 to fix the position of the trash bag inside the can body 100, preventing the trash bag from falling off due to overloading.

[0054] In this invention, to improve the user experience and optimize the steps of opening the trash can lid and changing the trash bag, a linkage mechanism is also provided. This linkage mechanism simultaneously drives the lid 200 to slide open and lifts the trash bag fixing part 300 above the can body 100. The opening process is optimized; as the lid 200 opens, the trash bag fixing part 300 automatically rises above the opening of the can body 100, making the opening process smoother and the process of changing the trash bag cleaner and more hygienic for the user.

[0055] A linkage mechanism is connected to one side of the bin body 100, and is connected to both the bin lid 200 and the garbage bag fixing part 300. When the linkage rod 410 rotates, the bin lid 200 moves synchronously with the linkage rod 410. When the user pulls the linkage rod 410, the bin lid 200 slides open from the opening of the bin body 100, and finally slides to rest against the side wall of the bin body 100. During the sliding opening of the bin lid 200, the linkage rod 410 drives the lifting drive part 420 to move, which lifts the bottom of the garbage bag fixing part 300 upward, raising the garbage bag fixing part 300 from above the bin body 100. This facilitates direct replacement of the garbage bag without requiring the user to reach into the garbage bag for replacement, making it cleaner and more hygienic.

[0056] This invention simultaneously opens the lid and lifts the garbage bag, resulting in a smooth and streamlined process with fewer steps. Existing sliding-lid garbage bins require users to open the lid 200 and then reach into the bin body 100 to remove the garbage bag. This process involves getting hands dirty before closing the lid 200, easily soiling it and leaving bacteria on the handle, leading to poor hygiene and requiring frequent wiping. Since the garbage bin is a wall-mounted design for kitchens, closer to the countertop, bacteria on the dirty lid 200 can easily come into contact with food, contaminating it. This invention creatively combines the opening and lifting of the garbage bag, simultaneously lifting the bag during the opening process, reducing user contact with the inside of the bag and allowing for direct bag removal and replacement, resulting in improved hygiene. Furthermore, the linkage mechanism is simple, low-cost, and operates smoothly without jamming, significantly enhancing the user experience of the wall-mounted garbage bin.

[0057] Specifically, a racetrack-shaped through hole 411 is provided on one side of the linkage 410, and a cylindrical protrusion extends from the position where the bucket lid 200 connects to the racetrack-shaped through hole 411. When the linkage 410 rotates, the cylindrical protrusion of the bucket lid 200 moves within the range of the racetrack-shaped through hole 411. When the linkage 410 is pulled down, the cylindrical protrusion moves upward along the racetrack-shaped through hole 411, causing the bucket lid 200 to slide forward on the top of the bucket body 100, separating from the top opening of the bucket body 100, thereby opening the opening of the bucket body 100.

[0058] In a further embodiment, such as Figures 2-4 and Figures 9-11 As shown, the linkage mechanism includes two sets, respectively disposed on both sides of the bucket body 100. The cylindrical protrusions on both sides of the bucket lid 200 are connected to the racetrack-shaped through holes 411 of the linkage rods 410 on both sides, making the sliding of the bucket lid 200 smoother. Specifically, the linkage rods 410 on both sides extend upward and approach each other to form a handle. In this embodiment, the handle is integrally formed, and the two sides of the handle are rotatably connected to the two sides of the bucket body 100, and the handle is used as the linkage rod 410. When the user opens the bucket lid 200, he only needs to hold the middle of the handle and push downward, which can simultaneously drive the lifting drive parts 420 on both sides, making the opening process smoother.

[0059] It should be understood that the structure of the linkage rod 410 as a handle is not the only implementation. In other embodiments, the linkage rod 410 can also be configured as a two-sided connecting rod structure according to actual production needs. When the user opens the lid 200, they need to push and pull the connecting rods on both sides simultaneously to open the lid 200 and lift the garbage bag fixing part 300. Alternatively, a structure in which the linkage rod 410 is driven by a motor can be used. The two linkage rods 410 on both sides are connected to a motor, and the two motors are connected by a control button. When the user presses the button, the motor drives the two linkage rods 410 on both sides, causing the lid 200 to slide open and lifting the garbage bag fixing part 300. The structure of the linkage rod 410 is not described in detail in this invention. It should be understood that any flexible changes to the structure of the linkage rod 410 without departing from the basic concept of this invention should be considered within the scope of protection defined by this invention.

[0060] In some embodiments of the present invention, such as Figures 2-15 As shown, the lifting drive unit 420 includes two embodiments.

[0061] First embodiment, such as Figures 2-7 As shown:

[0062] like Figures 4-7 As shown, the lifting drive unit 420 includes an eccentric drive disc 431 and a lifting rod 432. One side of the linkage rod 410 is inserted into a hole in the side wall of the barrel 100 and connected to one side of the eccentric drive disc 431. A stop is provided at one end of the drive rod 410 that is inserted into the barrel 100. During the insertion of the drive rod 410 into the barrel 100, the wall of the hole in the barrel 100 contacts the stop, restricting the drive rod 410 from further insertion into the barrel 100, which facilitates assembly.

[0063] A limiting structure 433 is provided at the connection between the eccentric drive disc 431 and the lifting rod 432. The limiting structure 433 is used to position the lid 200 to the normally open state and limit the rotation position of the eccentric drive disc 431. One end of the lifting rod 432 is connected to the side of the eccentric drive disc 431 away from the linkage rod 410, and the other end is slidably connected to the slide groove 111 on the side wall of the bin body 100. When the linkage rod 410 drives the eccentric drive disc 431 to rotate, the lifting rod 432 slides along the slide groove 111, and the lifting rod 432 slides upward and lifts the garbage bag fixing part 300.

[0064] In a further embodiment, such as Figure 6 and Figure 7As shown, the limiting structure 433 includes a reset groove 432-1, a normally open cover positioning groove 432-2, and a fitting protrusion 431-1. The fitting protrusion 431-1 is located at the eccentric drive disk 431, and the reset groove 432-1 and the normally open cover positioning groove 432-2 are respectively located on the periphery of one end of the lifting rod 432. When the linkage mechanism is in the initial state, the fitting protrusion 431-1 is engaged with the reset groove 432-1, that is, when the fitting protrusion 431-1 matches the reset groove 432-1, the linkage rod 410 is in the initial state.

[0065] When the linkage mechanism is activated, the eccentric drive disc 431 drives the engaging protrusion 431-1 to rotate around the connection point of the lifting rod 432. The engaging protrusion 431-1 separates from the reset groove 432-1 of the lifting rod 432. At this time, the linkage rod 410 drives the lid 200 to slide open from the top of the bin body 100. When the engaging protrusion 431-1 passes the limit of the normally open positioning groove 432-2 of the lid, the lid 200 slides to one side of the bin body 100 and reaches the designated opening position, while the lifting rod 432 lifts the garbage bag fixing part 300.

[0066] Second embodiment, such as Figures 9-14 As shown:

[0067] like Figures 12-14 As shown, the lifting drive unit 420 includes a limiting part 421, an eccentric turntable 422, and a lifting connecting rod 423. The limiting part 421 is connected to the inner side wall of the barrel 100. A connecting post extends from one side of the linkage rod 410. The connecting post is inserted into the opening in the side wall of the barrel 100 and passes through the limiting part 421 to connect with the eccentric turntable 422, thereby achieving the effect of the linkage rod 410 driving the eccentric turntable 422.

[0068] The eccentric turntable 422 is fitted and connected to the limiting part 421 on the side near the limiting part 421. The limiting part 421 is used to position the lid 200 in the open state and limit the rotation position of the eccentric turntable 422. That is, when the lid 200 is in the open state, the limiting part 421 can position the current position of the eccentric turntable 422 to prevent the lid 200 from sliding abnormally. Specifically, the side of the eccentric turntable 422 near the limiting part 421 is hollowed out, and the limiting part 421 can be inserted into the hollowed-out part of the eccentric turntable 422. The limiting part 421 is fixedly connected to the opening of the barrel body 100. When the linkage rod 410 drives the eccentric turntable 422 to rotate, the limiting part 421 remains in a stationary fixed state. After the eccentric turntable 422 rotates around the limiting part 421 to the designated position, the limiting part 421 restricts the rotation of the eccentric turntable 422 to prevent the lid 200 and the garbage bag fixing part 300 from exceeding the rotation position.

[0069] The other end of the eccentric turntable 422 is connected to one end of the lifting rod 423, and the other end of the lifting rod 423 is slidably connected to the slide groove 111 on the side wall of the bin 100. When the linkage rod 410 is pushed or pulled downward, it drives the eccentric turntable 422 to rotate, causing the lifting rod 423 to slide upward along the slide groove 111. During the upward sliding process, it contacts the bottom of the garbage bag fixing part 300 and lifts the garbage bag fixing part 300. When the linkage rod 410 returns to its original position, the lifting rod 423 slides downward along the slide groove 111, causing the garbage bag fixing part 300 to move downward and return to its original position.

[0070] In a further embodiment, such as Figure 13 and Figure 14 As shown, the periphery of the limiting part 421 is provided with a reset groove 421-1 and a normally open cover positioning groove 421-2, while the position where the eccentric turntable 422 engages with the limiting part 421 is provided with a limiting protrusion 422-1. The user can clearly understand the current working range of the linkage mechanism through the feedback generated by the contact between the limiting protrusion 422-1 and different parts of the limiting part 421.

[0071] When the linkage mechanism is in its initial state, the limiting protrusion 422-1 is engaged with the reset groove 421-1. When the linkage mechanism is activated, the eccentric turntable 422 drives the limiting protrusion 422-1 to rotate around the periphery of the limiting part 421, and the limiting protrusion 422-1 separates from the reset groove 421-1. When the limiting protrusion 422-1 passes the limit of the normally open positioning groove 421-2 of the lid, the lid 200 is fully open, and the lifting linkage 423 lifts the garbage bag fixing part 300.

[0072] Specifically, when the linkage mechanism is in its initial state, the limiting protrusion 422-1 is engaged with the reset groove 421-1, the linkage rod 410 is in its original state, the lid 200 is closed to the body 100, and the garbage bag fixing part 300 is located inside the body 100. When the linkage rod 410 drives the eccentric turntable 422 to rotate, the limiting protrusion 422-1 separates from the reset groove 421-1 of the limiting part 421, generating feedback so that the user can clearly feel the lifting drive part 420 working. When the limiting protrusion 422-1 rotates around the limiting part 421 to a specified angle, the limiting protrusion 422-1 engages with the normally open positioning groove 421-2 of the lid. At this time, the user continues to apply force, causing the limiting protrusion 422-1 to pass over the normally open positioning groove 421-2 of the lid, the lid 200 is fixed in the specified position, and the lifting linkage 423 lifts the garbage bag fixing part 300, entering the lifting state. The rotation angle of the limiting protrusion 422-1 between the reset groove 421-1 and the normally open positioning groove 421-2 of the lid is the opening process of the lid 200.

[0073] In a further embodiment, such as Figure 13As shown, the lifting link 423 includes a sliding part 423-1 and a lifting part 423-3. A sliding block 423-2 extends from one side of the sliding part 423-1, and the sliding block 423-2 is slidably connected to the groove 111. In this embodiment, the groove 111 is provided on one side of the garbage bag fixing part 300. To avoid interference between the sliding part 423-1 and the garbage bag fixing part 300, the sliding part 423-1 and the lifting part 423-3 are misaligned, that is, the sliding part 423-1 and the lifting part 423-3 are not on the same straight line, but the sliding part 423-1 and the lifting part 423-3 are integrally formed to form the lifting link 423. One side of the lifting part 423-3 of the lifting link 423 is connected to the eccentric turntable 422. The lifting part 423-3 is located below the garbage bag fixing part 300. When the lifting link 423 lifts the garbage bag fixing part 300, the periphery of the lifting part 423-3 contacts the bottom of the garbage bag fixing part 300, thereby pushing the garbage bag fixing part 300 to move upward.

[0074] It should be understood that the eccentric turntable 422 and the lifting linkage 423 are not the only implementation methods. In some other embodiments, the eccentric turntable 422 can be replaced with a gear, and the lifting linkage 423 can be replaced with a rack, depending on actual production needs. The rack and gear mesh, and the gear is connected to the linkage rod 410. When the linkage rod 410 is pushed down, the gear rotates, pushing the rack upward, thereby lifting the garbage bag fixing part 300. When the linkage rod 410 is reset, the gear reverses, driving the rack downward, thereby lowering the garbage bag fixing part 300 and resetting it. The structure of the lifting drive part 420 is not described in detail in this invention. It should be understood that the structure of the lifting drive part 420 can be flexibly changed without departing from the basic concept of this invention, and all such changes should be considered within the protection scope defined by this invention.

[0075] In some embodiments of the present invention, such as Figures 2-4 and Figures 9-11 As shown, an annular support portion 110 is connected to the top of the bin body 100, and the annular support portion 110 is detachably connected to the bin body 100. A sliding groove 111 is provided on the annular support portion 110, and multiple short support platforms 112 extend inward from the bottom periphery of the annular support portion 110. The short support platforms 112 are used to form the bottom of the garbage bag fixing portion 300. In this embodiment, there are four short support platforms 112, evenly distributed around the bottom periphery of the annular support portion 110. Specifically, when the garbage bag fixing portion 300 moves downward along the opening of the bin body 100, the bottom of the garbage bag fixing portion 300 contacts the short support platforms 112, reaching the maximum downward depth of the garbage bag fixing portion 300, while preventing the garbage bag fixing portion 300 from jamming against the side wall of the bin body 100 under the weight of the garbage bag.

[0076] It should be understood that the annular support portion 110 is not the only implementation. In some other embodiments, the barrel body 100 and the annular support portion 110 can be integrally formed according to actual production needs, with the sliding groove 111 directly provided on the side wall of the barrel body 100, and the short support platform 112 extending from the side wall of the barrel body 100. The structure of the annular support portion 110 will not be described in detail in this invention. It should be understood that any flexible changes to the structure of the annular support portion 110 without departing from the basic concept of this invention should be considered within the scope of protection defined by this invention.

[0077] It should be understood that the short support platform 112 is not the only implementation method. In some other embodiments, two long support platforms can be extended on both sides of the bottom of the annular support portion 110 according to actual production needs. The present invention does not describe the support structure of the garbage bag fixing portion 300 in detail. It should be understood that the support structure of the garbage bag fixing portion 300 can be flexibly changed without departing from the basic concept of the present invention, and all such changes should be considered as within the protection scope defined by the present invention.

[0078] In some embodiments of the present invention, such as Figure 2 , Figure 4 , Figure 9 and Figure 11 As shown, to make the lid 200 slide open more smoothly, multiple guide blocks 113 are provided on the top periphery of the bucket body 100, and the bottom of the lid 200 can move along the guide blocks 113. In this embodiment, the guide blocks 113 are provided on the top periphery of the annular support portion 110. Specifically, each guide block 113 is inclined towards the middle of the bucket body 100, and the lid 200 can move towards the middle of the bucket body 100 along the inclined direction of the guide blocks 113 during the closing process, achieving an automatic alignment effect. During the sliding opening process, the lid 200 slides along the inclined surface of the guide blocks 113, making it easier to slide out from the top of the bucket body 100, and the sliding is smoother and without jamming.

[0079] In some embodiments of the present invention, such as Figure 2 and Figure 8 As shown, the garbage bag fixing part 300 has fixing pressure holes 310 on both sides. The user puts the garbage bag through the middle of the garbage bag fixing part 300, and then puts the periphery of the garbage bag over the periphery of the garbage bag fixing part 300. The bag opening at the periphery of the garbage bag fixing part 300 is pressed into the fixing pressure hole 310, thereby fixing the position of the garbage bag.

[0080] It should be understood that fixing the pressure hole 310 is not the only implementation method; in some other embodiments, such as... Figure 9 and Figure 15As shown, a fixing ring 320 can also be used to secure the garbage bag. Multiple fan-shaped fixing members extend from the periphery of the fixing ring 320 towards the center. These fan-shaped fixing members are made of rubber and have good resilience. When the opening of the garbage bag is fixed within the fixing ring 320, the fan-shaped fixing members spring back to secure the garbage bag's position. This invention does not elaborate on each of the garbage bag's fixing structures. It should be understood that any flexible changes to the garbage bag's fixing structure without departing from the basic concept of this invention should be considered within the scope of protection defined by this invention.

[0081] It should be understood that the use of the fixing pressure hole 310 in the garbage bag fixing part 300 for fixing the garbage bag is not the only implementation. In some other embodiments, a double-layer fastening structure can also be used, where the garbage bag is fitted into the first fixing ring, and then the second fixing ring is fastened to the first fixing ring, so that the periphery of the garbage bag is sandwiched between the two fixing rings. The two fixing rings can also be connected by magnetic attraction. This invention does not describe the garbage bag fixing structure in the garbage bag fixing part 300 in detail. It should be understood that, without departing from the basic concept of this invention, flexible changes to the garbage bag fixing structure in the garbage bag fixing part 300 should all be considered within the protection scope defined by this invention.

[0082] In some embodiments of the present invention, such as Figure 2 , Figure 9 and Figure 16 As shown, the bin body 100 is provided with a top wall column 120, which is used to support the surface of the trash can.

[0083] In some embodiments of the present invention, the bin 100 is provided with a vent (not shown in the drawings) to expel air between the bin 100 and the garbage bag. The vent is located on the side wall of the bin 100. When the garbage bag is inserted into the garbage bag fixing part 300, the garbage bag needs to be pushed into the bin 100. If the air in the bin 100 is not completely expelled, the garbage bag cannot fully unfold. When the garbage bag contains garbage, the air inside the bin 100 will prevent the garbage bag from extending further into the bin 100, resulting in a reduction in the usable capacity of the garbage bag. By providing a vent on the side wall of the bin 100, when the garbage bag unfolds into the bin 100, the air inside the bin 100 is expelled through the vent, allowing the garbage bag to fully unfold and effectively utilize its capacity. Providing the vent on the side wall effectively achieves venting while preventing liquid from the garbage bag from leaking out. If the vent were located at the bottom of the bin 100, leaked liquid from the garbage bag would flow out from the bottom vent, polluting the kitchen environment.

[0084] It should be understood that providing vent holes on the side wall of the barrel 100 is not the only implementation method. In some other embodiments, the barrel 100 can also adopt a structure with hollowed-out side walls for venting. This invention will not describe the venting structure of the barrel 100 in detail. It should be understood that, without departing from the basic concept of this invention, the venting structure of the barrel 100 can be flexibly changed, and all such changes should be considered within the protection scope defined by this invention.

[0085] In some embodiments of the present invention, such as Figure 2 , Figure 9 , Figure 10 and Figure 16 As shown, the outer wall of the bucket body 100 is provided with a wall-mounting component 130, which is detachably connected to the outer wall of the bucket body 100. The wall-mounting component 130 includes S-shaped hooks, wall panel hooks, and U-shaped hooks, etc. Users can replace different wall-mounting components 130 according to the usage environment. In this embodiment, the side wall of the bucket body 100 is provided with a sliding groove. One side of the wall-mounting component 130 is slidably connected to the sliding groove, and the other side is hooked onto the wall, cabinet door, or other positions.
