[0002] Trash cans are common sanitary appliances in our daily lives. There are many different types of trash cans, and their sizes and opening and closing methods vary depending on the location. Currently, there are two main types of trash cans used indoors: floor-standing and wall-mounted. Floor-standing trash cans are primarily used in bedrooms, living rooms, and dining rooms, while wall-mounted trash cans are primarily used in kitchens.

[0003] In order to facilitate the collection of kitchen waste, the kitchen trash can usually adopts a back-hanging structure. The trash can is directly hung on the door frame of the kitchen cabinet through a hook, making it convenient for users to sweep the kitchen waste directly from the counter into the trash can.

[0004] The internal structure of the kitchen wall-mounted trash cans currently on the market is complex and the cost is high. The garbage bag is directly put on the top circumference of the trash can. When the user wants to change the garbage bag, he needs to reach into the can to pick up the bag. The kitchen waste in the garbage bag is a mixture of dry and wet, which can easily dirty the user's hands. For this reason, a press-and-clamp bag mechanism has appeared on the market, but the assembly structure is relatively complex. During use, the user still needs to reach into the can to disassemble the press-and-clamp bag mechanism, which is inconvenient to disassemble. Summary of the Invention

[0046] Reference below Figures 1-16 A wall-mounted trash can according to an embodiment of the present invention is described.

[0047] like Figures 1-16 As shown, comprising a barrel 100, a garbage bag fixing portion 300 and a linkage mechanism.

[0048] The garbage bag fixing portion 300 is slidably disposed at the top of the barrel body 100 to fix the garbage bag in the barrel body 100 .

[0049] The linkage mechanism is connected to one side of the garbage bag holder 100 and is connected to the garbage bag holder 300, for lifting the garbage bag holder 300 above the garbage bag holder 100. The linkage mechanism includes a linkage rod 410 and a lifting drive 420. The linkage rod 410 is connected to the lifting drive 420, which is located below the garbage bag holder 300. When the linkage rod 410 rotates, the lifting drive 420 moves with the linkage rod 410 to lift the bottom of the garbage bag holder 300.

[0050] Specifically, the linkage mechanism includes a linkage rod portion 410 and a lifting drive portion 420. The linkage rod portion 410 is arranged on the outside of the barrel body 100, with one side connected to the barrel cover 200 and the other side connected to the lifting drive portion 420. The lifting drive portion 420 is arranged on the inside of the barrel body 100 and is located below the garbage bag fixing portion 300. The lifting drive portion 420 lifts the bottom of the garbage bag fixing portion 300 upward, so that the garbage bag fixing portion 300 is lifted from the position above the barrel body 100, which is convenient for directly replacing the garbage bag without the user reaching into the garbage bag to replace it, which is cleaner and more hygienic.

[0051] In some embodiments of the present invention, Figure 1-Figure 4 and Figures 9-11 As shown, the wall-mounted trash can includes a lid 200 that covers the top opening of the body 100 and is used to cover the opening of the body 100 to prevent the garbage inside the body 100 from coming into contact with the outside world, causing it to rot or breed mosquitoes. A trash bag fixing portion 300 is provided at the top of the body 100. The trash bag fixing portion 300 is vertically inserted into the body 100 and slides perpendicular to the end face of the body 100 to fix the position of the trash bag in the body 100 and prevent the bag from falling off due to excessive garbage in the bag.

[0052] In the present invention, in order to enhance the user experience and optimize the steps of opening the lid and changing the trash bag, a linkage mechanism is also provided. The linkage mechanism is used to simultaneously drive the lid 200 to slide open and lift the trash bag fixing part 300 to above the barrel body 100. The lid opening process is optimized. During the opening process of the lid 200, the trash bag fixing part 300 is automatically lifted above the opening of the barrel body 100, making the lid opening process smoother and the user's trash bag changing process cleaner and more hygienic.

[0053] The linkage mechanism is connected to one side of the barrel body 100, and the linkage mechanism is respectively connected to the barrel cover 200 and the garbage bag fixing part 300. When the linkage rod part 410 rotates, the barrel cover 200 moves synchronously with the linkage rod part 410 under the drive of the linkage rod part 410. The user pulls the linkage rod part 410, and the barrel cover 200 slides open from the opening of the barrel body 100, and finally slides to lean against the side wall of the barrel body 100. During the sliding opening process of the barrel cover 200, the linkage rod part 410 drives the jacking drive part 420 to move, and the jacking drive part 420 jacks up the bottom of the garbage bag fixing part 300, so that the garbage bag fixing part 300 is lifted from the position above the barrel body 100, which is convenient for directly replacing the garbage bag. There is no need for the user to reach into the garbage bag to replace it, which is cleaner and more hygienic.

[0054] The lid opening and bag lifting actions are completed simultaneously during the opening process, ensuring a smooth and seamless process with fewer steps. Existing sliding-lid trash cans require users to open the lid 200 and then reach into the body 100 to remove the trash bag. Closing the lid 200 after hands become soiled during this process can easily soil the lid 200 and allow bacteria to remain on the handles, resulting in poor hygiene and the need for users to frequently wipe the trash can. Because the trash can is wall-mounted in the kitchen, it is closer to the countertop, making it extremely easy for bacteria on the dirty lid 200 to come into contact with food on the countertop, contaminating the food. The wall-mounted trash can of the present invention innovatively combines the lid opening and bag lifting actions, simultaneously completing the bag lifting process during the lid opening process. This reduces user contact with the contents of the trash bag, allowing users to directly remove the bag opening to complete the bag change, resulting in a more hygienic experience. Furthermore, the linkage mechanism is simple in structure, low in manufacturing cost, and operates smoothly and without lag, significantly enhancing the user experience of the wall-mounted trash can.

[0055] Specifically, a racetrack-shaped through-hole 411 is provided on one side of the linkage rod 410, and a cylindrical boss is provided extending from the position where the lid 200 connects to the racetrack-shaped through-hole 411. When the linkage rod 410 rotates, the cylindrical boss of the lid 200 moves within the range of the racetrack-shaped through-hole 411. Pulling down the linkage rod 410 causes the cylindrical boss to move upward along the racetrack-shaped through-hole 411, thereby causing the lid 200 to slide forward on the top of the barrel body 100, separating from the top opening of the barrel body 100, and thus opening the barrel body 100.

[0056] In a further embodiment, Figure 2-Figure 4 and Figures 9-11As shown, the linkage mechanism includes two groups, which are respectively arranged on both sides of the barrel body 100. The cylindrical bosses on both sides of the barrel cover 200 are respectively connected to the runway-shaped through holes 411 of the linkage rods 410 on both sides, so that the barrel cover 200 can slide more smoothly. 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 respectively rotatably connected to the two sides of the barrel body 100, and the handle is used as the linkage rod 410. When the user opens the barrel cover 200, he only needs to hold the middle of the handle and push and pull it downward to simultaneously drive the lifting drive parts 420 on both sides, making the opening process smoother.

[0057] It should be understood that the structure in which the linkage rod 410 is configured as a handle is not the only embodiment. In some other embodiments, the linkage rod 410 can also be configured as a structure with two connecting rods according to actual production needs. When the user opens the bucket lid 200, he needs to push and pull the connecting rods on both sides with both hands at the same time, thereby opening the bucket lid 200 and lifting the garbage bag fixing part 300. A structure in which a motor drives the linkage rod 410 can also be adopted. The linkage rods 410 on both sides are respectively connected to motors, and the two motors are connected by a control button. When the user presses the button, the motor drives the linkage rods 410 on both sides, causing the bucket lid 200 to slide open and lift the garbage bag fixing part 300. The present invention does not elaborate on the structure of the linkage rod 410 one by one. It should be understood that, without departing from the basic concept of the present invention, the flexible transformation of the structure of the linkage rod 410 should be considered within the scope of protection defined by the present invention.

[0058] In some embodiments of the present invention, Figure 2-Figure 15 As shown, the lifting drive unit 420 includes two embodiments.

[0059] The first embodiment, as Figure 2-Figure 7 As shown:

[0060] like Figure 4-Figure 7 As shown, the lifting drive unit includes an eccentric driving disk 431 and a lifting rod 432. One side of the linkage rod 410 is inserted into the hole in the side wall of the barrel body 100 and connected to one side of the eccentric driving disk 431. A stopper is provided at one end of the driving rod 410 inserted into the barrel body 100. During the insertion of the driving rod 410 into the barrel body 100, the hole wall of the barrel body 100 contacts the stopper, limiting the driving rod 410 from being further inserted into the barrel body 100, thereby facilitating assembly.

[0061] 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 rotational 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 portion 410, and the other end is slidably connected to the slide groove 111 on the side wall of the barrel body 100. When the linkage rod portion 410 drives the eccentric drive disc 431 to rotate, the lifting rod 432 slides along the slide groove 111, slides upward, and lifts the garbage bag fixing portion 300.

[0062] In a further embodiment, Figure 6 and Figure 7 As shown, the limiting structure 433 includes a reset groove 432-1, a lid normally open positioning groove 432-2, and an engaging protrusion 431-1. The engaging protrusion 431-1 is provided on the eccentric drive disk 431, and the reset groove 432-1 and the lid normally open positioning groove 432-2 are respectively provided on the periphery of one end of the lifting rod 432. When the linkage mechanism is in the initial state, the engaging protrusion 431-1 is engaged with the reset groove 432-1, that is, when the engaging protrusion 431-1 and the reset groove 432-1 match, the linkage rod portion 410 is in the initial state.

[0063] When the linkage mechanism is activated, the eccentric drive disc 431 drives the engaging projection 431-1 to rotate about the connection point of the lifting rod 432, and the engaging projection 431-1 separates from the return groove 432-1 of the lifting rod 432. At this time, the linkage rod portion 410 drives the lid 200 to slide open from the top of the barrel body 100. When the engaging projection 431-1 passes the limit of the lid normally open positioning groove 432-2, the lid 200 slides to the side of the barrel body 100 and reaches the designated open position, and the lifting rod 432 lifts up the garbage bag fixing portion 300.

[0064] The second embodiment, as Figures 9-14 As shown:

[0065] like Figure 12-14 As shown, the lifting drive unit 420 includes a limiter 421, an eccentric rotary disc 422, and a lifting connecting rod 423. The limiter 421 is connected to the inner side wall of the barrel body 100. A connecting post is extended from one side of the linkage rod 410. The connecting post is inserted into the opening of the side wall of the barrel body 100 and passes through the limiter 421 to connect with the eccentric rotary disc 422, so that the linkage rod 410 can drive the eccentric rotary disc 422.

[0066] The side of the eccentric rotating disk 422 close to the limiting portion 421 is engaged with the limiting portion 421. The limiting portion 421 is used to locate the position of the bucket cover 200 in the open state and limit the rotation position of the eccentric rotating disk 422. That is, when the bucket cover 200 is in the open state, the limiting portion 421 can locate the current position of the eccentric rotating disk 422 to prevent the bucket cover 200 from sliding abnormally. Specifically, the side of the eccentric rotating disk 422 close to the limiting portion 421 is hollowed out, and the limiting portion 421 can be embedded in the hollowed-out part of the eccentric rotating disk 422. The limiting portion 421 is relatively fixedly connected to the opening of the barrel body 100. When the linkage rod 410 drives the eccentric rotating disk 422 to rotate, the limiting portion 421 is always in a stationary and fixed state. After the eccentric turntable 422 rotates around the limiting portion 421 to a specified position, the limiting portion 421 limits the rotation of the eccentric turntable 422 to prevent the bucket cover 200 and the garbage bag fixing portion 300 from exceeding the rotation position.

[0067] The other end of the eccentric rotating disc 422 is connected to one end of a lifting link 423, the other end of which is slidably connected to a chute 111 on the side wall of the barrel 100. When the linkage rod 410 is pushed or pulled downward, the linkage rod 410 drives the eccentric rotating disc 422 to rotate, causing the lifting link 423 to slide upward along the chute 111. During the upward sliding process, the lifting link 423 contacts the bottom of the garbage bag fixing portion 300 and lifts the garbage bag fixing portion 300. When the linkage rod 410 is reset upward, the lifting link 423 slides downward along the chute 111, causing the garbage bag fixing portion 300 to move downward and return to its original position.

[0068] In a further embodiment, Figure 13 and Figure 14 As shown, the periphery of the stopper 421 is provided with a reset groove 421-1 and a lid normally open positioning groove 421-2, while a limit bump 422-1 is provided where the eccentric rotating disk 422 engages the stopper 421. The user can understand the current operating range of the linkage mechanism through the feedback generated by the contact between the limit bump 422-1 and different parts of the stopper 421.

[0069] When the linkage mechanism is in its initial state, the limiting protrusion 422-1 engages with the reset groove 421-1. When the linkage mechanism is activated, the eccentric rotating disk 422 drives the limiting protrusion 422-1 to rotate around the periphery of the limiting portion 421, separating the limiting protrusion 422-1 from the reset groove 421-1. When the limiting protrusion 422-1 passes the limit of the lid's normally-open positioning groove 421-2, the lid 200 is fully opened, and the lifting link 423 lifts the garbage bag fixing portion 300.

[0070] Specifically, when the linkage mechanism is in the initial state, the limiting protrusion 422-1 is engaged with the reset groove 421-1. At this time, the linkage rod 410 is in the original state, the bucket lid 200 and the bucket body 100 remain closed, and the garbage bag fixing part 300 is located inside the bucket body 100. When the linkage rod 410 drives the eccentric rotating disk 422 to rotate, the limiting protrusion 422-1 separates from the reset groove 421-1 of the limiting part 421, and a feedback is generated at this time, allowing the user to clearly feel that the lifting drive unit 420 is working. When the limiting protrusion 422-1 rotates around the limiting part 421 to a specified angle, the limiting protrusion 422-1 is engaged with the lid normally open positioning groove 421-2. At this time, the user continues to apply force, causing the limiting protrusion 422-1 to pass over the lid normally open positioning groove 421-2, and the bucket lid 200 is fixed in the specified position. The lifting connecting rod 423 lifts the garbage bag fixing part 300, and the bucket lid 200 enters the lifting state. The rotation angle of the limiting protrusion 422 - 1 between the reset groove 421 - 1 and the lid normally open positioning groove 421 - 2 is the opening process of the barrel cover 200 .

[0071] In a further embodiment, Figure 13 As shown, the lifting link 423 includes a sliding portion 423-1 and a lifting portion 423-3. A sliding block 423-2 extends from one side of the sliding portion 423-1, and the sliding block 423-2 is slidably connected to the sliding groove 111. In this embodiment, the sliding groove is provided on one side of the garbage bag fixing portion 300. To prevent interference between the sliding portion 423-1 and the garbage bag fixing portion 300, the sliding portion 423-1 and the lifting portion 423-3 are staggered, that is, the sliding portion 423-1 and the lifting portion 423-3 are not in the same straight line. However, the sliding portion 423-1 and the lifting portion 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 to the west of 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.

[0072] It should be understood that the eccentric turntable 422 and the lifting connecting rod 423 are not the only implementation methods. In some other embodiments, the eccentric turntable 422 can be replaced with a gear, and the lifting connecting rod 423 can be replaced with a rack according to actual production needs. The rack and the gear are meshed, and the gear is connected to the linkage rod 410. When the linkage rod 410 is pushed and pulled downward, 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 present invention does not elaborate on the structure of the lifting drive part 420. It should be understood that, without departing from the basic concept of the present invention, the flexible transformation of the structure of the lifting drive part 420 should be considered within the scope of protection defined by the present invention.

[0073] In some embodiments of the present invention, Figure 2-Figure 4 and Figures 9-11 As shown, the top of the barrel body 100 is connected to an annular supporting portion 110, and the annular supporting portion 110 is detachably connected to the barrel body 100. The slide groove 111 is provided on the annular supporting portion 110, and a plurality of short supports 112 extend inward from the bottom periphery of the annular supporting portion 110. The short supports 112 are used to form the bottom of the garbage bag fixing portion 300. In this embodiment, the number of the short supports 112 is four, which are evenly distributed on the bottom periphery of the annular supporting portion 110. Specifically, when the garbage bag fixing portion 300 moves downward along the opening of the barrel body 100, the bottom of the garbage bag fixing portion 300 contacts the short supports 112, reaching the maximum downward movement depth of the garbage bag fixing portion 300, while preventing the garbage bag fixing portion 300 from being stuck to the side wall of the barrel body 100 under the action of the gravity of the garbage bag.

[0074] It should be understood that the annular support portion 110 is not the only embodiment. In other embodiments, the barrel body 100 and the annular support portion 110 can be integrally formed according to actual production requirements, with the chute 111 directly provided on the side wall of the barrel body 100 and the short support 112 extending from the side wall of the barrel body 100. The present invention does not elaborate on the structure of the annular support portion 110. It should be understood that, without departing from the basic concept of the present invention, the flexible modification of the structure of the annular support portion 110 should be considered within the scope of protection defined by the present invention.

[0075] It should be understood that the short support 112 is not the only embodiment. In other embodiments, two long supports may be extended on both sides of the bottom of the annular support portion 110 according to actual production requirements. The present invention does not describe the support structure of the garbage bag fixing portion 300 in detail. It should be understood that flexible changes in the support structure of the garbage bag fixing portion 300 without departing from the basic concept of the present invention should be considered within the scope of protection defined by the present invention.

[0076] In some embodiments of the present invention, Figure 2 、 Figure 4 、 Figure 9 and Figure 11As shown, in order to make the barrel cover 200 slide open more smoothly, a plurality of guide blocks 113 are provided on the top periphery of the barrel body 100, and the bottom of the barrel cover 200 can be guided and moved along the guide blocks 113. In this embodiment, the guide blocks 113 are provided on the top periphery of the annular supporting portion 110. Specifically, each guide block 113 is tilted toward the middle of the barrel body 100, and the barrel cover 200 can move toward the middle of the barrel body 100 along the tilted direction of the guide block 113 during the closing process, thereby achieving an automatic alignment effect. During the sliding opening process of the barrel cover 200, the barrel cover 200 slides along the inclined surface of the guide block 113, making it easier to slide out from the top of the barrel body 100, and the sliding is smoother and less stuck.

[0077] In some embodiments of the present invention, Figure 2 and Figure 8 As shown, fixed pressure holes 310 are provided on both sides of the garbage bag fixing part 300. The user passes the garbage bag through the middle of the garbage bag fixing part 300, and then puts the periphery of the garbage bag on 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 fixed pressure holes 310, thereby fixing the position of the garbage bag.

[0078] It should be understood that the fixed pressure hole 310 is not the only embodiment. In some other embodiments, such as Figure 9 and Figure 15 As shown, a fixed pressure ring 320 can also be used to secure the garbage bag. Extending from the periphery of the fixed pressure ring 320 toward the center are multiple fan-shaped fixing members. The fan-shaped fixing members are made of rubber and have good resilience. When the opening of the garbage bag is fixed within the fixed pressure ring 320, the fan-shaped fixing members rebound to secure the garbage bag in place. The present invention does not elaborate on the fixing structure of the garbage bag. It should be understood that flexible changes in the fixing structure of the garbage bag, without departing from the basic concept of the present invention, should be considered within the scope of protection defined by the present invention.

[0079] It should be understood that the use of the fixed pressure hole 310 structure in the garbage bag fixing portion 300 to fix the garbage bag is not the only embodiment. In some other embodiments, a double-layer buckled structure can also be used. The garbage bag is inserted into the first layer of fixing ring, and then the second layer of fixing ring is buckled with the first layer of fixing ring, so that the periphery of the garbage bag is clamped between the two layers of fixing rings. The two fixing rings can also be combined by magnetic fixation. The present invention does not elaborate on the garbage bag fixing structure in the garbage bag fixing portion 300. It should be understood that, without departing from the basic concept of the present invention, the flexible transformation of the garbage bag fixing structure in the garbage bag fixing portion 300 should be regarded as within the scope of protection defined by the present invention.

[0080] In some embodiments of the present invention, Figure 2 、 Figure 9 and Figure 16As shown, the barrel body 100 is provided with a top wall column 120, and the top wall column 120 is used to support the supporting surface of the trash can.

[0081] In some embodiments of the present invention, the barrel 100 is provided with an exhaust hole (not shown in the drawings) to exhaust air between the barrel 100 and the garbage bag. The exhaust hole is located in the side wall of the barrel 100. When the garbage bag is inserted into the garbage bag fixing portion 300, it needs to be pushed into the barrel 100. If the air in the barrel 100 is not completely exhausted, the garbage bag cannot be fully expanded. When the garbage bag is filled with garbage, the air in the barrel 100 will prevent the garbage bag from extending into the barrel 100, resulting in a reduction in the usable capacity of the garbage bag. The exhaust hole is located in the side wall of the barrel 100. When the garbage bag is expanded into the barrel 100, the air in the barrel 100 is discharged through the exhaust hole, allowing the garbage bag to fully expand and effectively utilize the garbage bag's capacity. The exhaust hole is located in the side wall to effectively achieve exhaust and prevent liquid in the garbage bag from escaping through the exhaust hole. If the exhaust hole is located at the bottom of the barrel 100, the liquid leaking from the garbage bag will flow out of the bottom exhaust hole and pollute the kitchen environment.

[0082] It should be understood that the provision of vent holes in the sidewall of the barrel 100 is not the only embodiment. In some other embodiments, the barrel 100 may also adopt a hollowed-out sidewall structure for venting. The present invention does not elaborate on the venting structure of the barrel 100 one by one. It should be understood that, without departing from the basic concept of the present invention, the venting structure of the barrel 100 can be flexibly changed and should be considered within the scope of protection defined by the present invention.

[0083] In some embodiments of the present invention, Figure 2 、 Figure 9 、 Figure 10 and Figure 16 As shown, the outer wall of the barrel body 100 is provided with a wall hanging member 130, which is detachably connected to the outer wall of the barrel body 100. The wall hanging member 130 includes an S-shaped hook, a wall plate hook, a U-shaped hook, etc. The user can replace different wall hanging members 130 to match the usage environment. In this embodiment, the side wall of the barrel body 100 is provided with a sliding slot. One side of the wall hanging member 130 is slidably connected to the sliding slot, and the other side is hooked to a wall, a cabinet door panel, etc.
