[0017] In one embodiment, the top of the first guide member is provided with two limiting portions, which are located on both sides of the top opening of the first guide groove. The two limiting portions form a clearance opening, which communicates with the first guide groove. The clearance opening allows the moving member to pass through, and the width of the clearance opening is smaller than the width of the first roller, so as to restrict the first roller within the first guide groove.

[0018] In one embodiment, the two limiting portions also form an installation port, the installation port connecting the first guide groove and the clearance port, the installation port being used for the first roller to enter and exit the first guide groove.

Each set of third rollers is in rolling cooperation with the corresponding second guide component.

[0035] The advantages or beneficial effects of the above technical solutions include at least the following:

[0036] This utility model discloses a waste collection device. A sliding cover is slidably mounted on an inclined section along its extension direction. The inclined section is positioned from back to front and then downwards. This allows the cover to slide down the inclined section when no external force is applied. Therefore, after releasing the foot pedal, the cover, foot pedal, and linkage mechanism together form a gravity-driven system. This system applies sufficient downward driving force to the cover to overcome the friction between the cover and the inclined section, thus achieving automatic closing of the cover. Because this waste collection device cleverly utilizes the gravity of the cover, foot pedal, and linkage mechanism as the driving force for the cover's return, it eliminates the need for a return spring used in conventional designs, simplifying the overall structure and reducing the number of parts. This reduces manufacturing and maintenance costs and facilitates the widespread application of waste collection devices.

[0047] In the following description, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments can be modified in various ways without departing from the spirit or scope of this application. Therefore, the drawings and description are considered to be exemplary in nature and not restrictive.

[0048] See Figures 1-6 This invention illustrates a preferred embodiment of a waste collection device, comprising:

[0049] The support base 1 is provided with an inclined part 11 and a garbage disposal port 12 located on the inclined part 11. The inclined part 11 extends from back to front and downward at an angle, that is, the inclined part 11 extends along the front-back direction of the support base 1, and the inclined part 11 is set at an angle downward toward the front side of the support base 1.

[0050] Foot pedal component 2 is hinged to the support base 1;

[0051] Linkage mechanism 3, the first end of linkage mechanism 3 is hinged to foot pedal component 2; and

[0052] The sliding cover 4 is slidably disposed on the inclined part 11 along the extension direction of the inclined part 11. The sliding cover 4 is connected to the second end of the linkage mechanism 3. The sliding cover 4 is used to close or open the garbage disposal port 12.

[0053] When the foot pedal component 2 is stepped on, the sliding cover 4 can move upward with the linkage mechanism 3 to open the garbage disposal port 12;

[0054] When the foot pedal 2 is released, the sliding cover 4 can move downward under the action of gravity to close the garbage disposal port 12.

[0055] This utility model's waste collection device features a sliding cover 4 that can slide up and down along the extension direction of an inclined portion 11. The inclined portion 11 is positioned obliquely downwards from back to front, giving the sliding cover 4 a tendency to slide down the inclined portion 11 when no external force is applied. Therefore, after releasing the foot pedal 2, the sliding cover 4, foot pedal 2, and linkage mechanism 3 together form a gravity-driven system. This system applies sufficient downward driving force to the sliding cover 4 to overcome the friction between the sliding cover 4 and the inclined portion 11, thereby achieving automatic closing of the sliding cover 4. Because this waste collection device cleverly utilizes the gravity of the sliding cover 4, foot pedal 2, and linkage mechanism 3 as the driving force for the sliding cover 4 to return to its original position, it eliminates the need for a return spring used in conventional designs, simplifying the overall structure and reducing the number of parts. This reduces manufacturing and maintenance costs and facilitates the widespread application of waste collection devices.

[0056] In one embodiment, the angle between the inclined portion 11 and the horizontal plane is preferably set to 30°, which ensures that the sliding cover 4 has a tendency to slide down along the inclined portion 11 when not subjected to external force, while also making it convenient for users to dispose of garbage.

[0057] Of course, in other embodiments, the angle between the inclined portion 11 and the horizontal plane can be set to any value among 31°-45°.

[0058] See Figures 3-6 In one embodiment, the linkage mechanism 3 includes:

[0059] The push-up component 31 is movably mounted on the support base 1, and the lower end of the push-up component 31 is hinged to the foot pedal component 2.

[0060] The first guide component 32 is fixedly connected to the upper end of the push-up component 31. The first guide component 32 has a first guide groove 321, which extends along the sliding direction of the sliding cover 4.

[0061] The upper end of the movable component 33 is fixedly connected to the sliding cover 4, and the lower end of the movable component 33 is movably inserted into the first guide groove 321. Thus, when the foot pedal 2 is stepped on, the foot pedal 2 swings around the fulcrum, thereby pushing the upward push component 31 upward. The upward push component 31 drives the connected first guide component 32 to move upward synchronously. Under the guidance and constraint of the first guide groove 321, the movable component 33 moves upward along the first guide groove 321, thereby driving the sliding cover 4 upward and opening the garbage disposal opening 12. When the foot pedal 2 is released, the sliding cover 4 automatically moves downward under gravity, closing the garbage disposal opening 12. At the same time, the movable component 33 moves downward along the first guide groove 321, pushing the first guide component 32 and the upward push component 31 downward, ultimately causing the foot pedal 2 to swing back to its initial position, completing the reset. The first guide groove 321 and the moving part 33 constitute a guide assembly, which can effectively constrain the degree of freedom of the sliding cover 4 during the movement process, ensuring that the sliding cover 4 can only slide smoothly up and down along the agreed trajectory, avoiding swaying and jamming, so that the sliding cover 4 can be reliably opened or closed.

[0062] See Figure 6 In one embodiment, the lower end of the moving part 33 is provided with a first roller 34, which rolls with the first guide groove 321. The sliding cover 4 is driven to slide by the first roller 34 rolling along the first guide groove 321. Rolling friction replaces sliding friction, which can reduce moving resistance, wear and operating noise, thereby making the sliding cover 4 move more smoothly and stably.

[0063] Of course, in other embodiments, the lower end of the moving part 33 can be set as a slider, which can slide in conjunction with the first guide groove 321, and can also move and guide the sliding cover 4.

[0064] See Figure 6 In one embodiment, the top of the first guide member 32 is provided with two limiting parts 322, which are respectively placed on both sides of the top opening of the first guide groove 321. The two limiting parts 322 form a clearance opening, which is connected to the first guide groove 321. The clearance opening allows the moving member 33 to pass through, so as to allow the moving member 33 to move. The width of the clearance opening is smaller than the width of the first roller 34, so as to restrict the first roller 34 within the first guide groove 321, prevent the first roller 34 from disengaging from the first guide groove 321 during movement, and improve the structural reliability.

[0065] See Figure 6 To facilitate the installation of the first roller 34 into the first guide groove 321, in one embodiment, the two limiting parts 322 also form an installation port 323. The installation port 323 connects the first guide groove 321 and the clearance port, and the installation port 323 is used to allow the first roller 34 to enter and exit the first guide groove 321.

[0066] See Figure 6 In one embodiment, first rollers 34 are provided on both the left and right sides of the moving part 33 to improve the moving stability of the moving part 33.

[0067] See Figures 3-6 In one embodiment, the linkage mechanism 3 further includes:

[0068] The hydraulic rod 35 has a fixed end that is hinged to the support base 1 and a movable end that is hinged to the push-up component 31.

[0069] When the foot pedal component 2 is stepped on, the movable end of the hydraulic rod 35 can extend as the push component 31 moves.

[0070] When the foot pedal component 2 is released, the movable end of the hydraulic rod 35 is shortened by gravity to provide a buffering effect, ensuring that the sliding cover 4 closes smoothly and without impact.

[0071] Of course, in other embodiments, the linkage mechanism 3 can be a linkage mechanism, which includes:

[0072] The first link, the lower end of the first link is hinged to the foot pedal component 2;

[0073] The second link, the lower end of which is hinged to the upper end of the first link; and

[0074] The lower end of the third link is hinged to the upper end of the second link, and the upper end of the third link is hinged to the sliding cover 4.

[0075] See Figure 5 In one embodiment, the waste collection device further includes:

[0076] The first guide mechanism 5 is disposed between the support base 1 and the push-up component 31. The first guide mechanism 5 is used to guide the movement of the push-up component 31, so as to guide and constrain the push-up component 31, thereby effectively constraining the degree of freedom of the push-up component 31 during the movement process, ensuring that the push-up component 31 can only move up and down smoothly and steadily along the agreed trajectory, avoiding swaying and jamming, so that the push-up component 31 can reliably push the guide component or the foot pedal component 2.

[0077] See Figure 5 In one embodiment, the first guide mechanism 5 includes:

[0078] A third guide component 51 is disposed on the support base 1, and the third guide component 51 has a third guide groove; and

[0079] The fourth roller 52 is rotatably mounted on the push-up component 31. The fourth roller 52 rolls in cooperation with the third guide groove. Thus, when the push-up component 31 moves, the fourth roller 52 rolls along the third guide groove to guide and constrain the push-up component 31. Rolling friction replaces sliding friction, which can reduce moving resistance, wear and operating noise, thereby making the sliding cover 4 move more smoothly and stably.

[0080] Of course, in other embodiments, the first guide mechanism 5 may also adopt a structure in which a guide rail and a slider cooperate, wherein the guide rail is disposed on the support base 1, the slider is disposed on the guide rail and can slide up and down, and the slider is connected to the push-up component 31.

[0081] Of course, in other embodiments, the first guide mechanism 5 may also adopt a structure in which a guide post and a guide sleeve cooperate, wherein the guide post is disposed on the support base 1, the guide sleeve is slidably sleeved on the guide post, and the guide sleeve is connected to the push-up component 31.

[0082] See Figure 3 In one embodiment, the support base 1 has a cavity 13 located below the inclined portion 11 and the cavity 13 is connected to the garbage disposal port 12.

[0083] The foot pedal component 2, the linkage mechanism 3, and the sliding cover 4 are all located inside the cavity 13, reducing the number of external protruding parts and making the overall structure of the garbage collection device more compact and simpler in appearance, thereby saving space. At the same time, the simpler appearance of the garbage collection device can reduce sanitary dead corners and facilitate cleaning and maintenance.

[0084] See Figure 3 In one embodiment, the support base 1 has an inlet and outlet on one side, which are connected to the cavity 13. The inlet and outlet are controlled to be closed or opened by a door panel 14 that is movably disposed on the front side of the support base 1.

[0085] The waste collection system also includes:

[0086] A garbage collection container (not shown in the figure) is placed inside the cavity 13. The garbage collection container enters and exits the cavity 13 through the inlet and outlet so that cleaning personnel can pull the garbage collection container out of the support base 1 to clean up the garbage. The garbage collection container has a garbage collection cavity, which is located directly below the garbage disposal port 12 and connected to the garbage disposal port 12.

[0087] See Figures 1-3 In one embodiment, the number of garbage disposal opening 12, foot pedal component 2, linkage mechanism 3, sliding cover 4 and garbage collection container can be set to one or two or more. When there are two or more, the sliding cover 4 is used to close or open a corresponding garbage disposal opening 12, the foot pedal component 2 is hinged to the corresponding linkage mechanism 3, the linkage mechanism 3 is connected to the corresponding sliding cover 4, and the garbage collection container is set below the corresponding garbage disposal opening 12.

[0088] See Figure 3 In one embodiment, the waste collection device further includes:

[0089] A baffle 6 is disposed within the cavity 13 and divides the cavity 13 into a first inner cavity 131 and a second inner cavity 132. The first inner cavity 131 accommodates at least a portion of the linkage component, and the second inner cavity 132 accommodates the waste collection container. By separating the first inner cavity 131 and the second inner cavity 132 by the baffle 6, waste can be effectively prevented from entering the first inner cavity 131, thereby protecting the linkage mechanism 3 from contamination, corrosion, or jamming, and improving the reliability and durability of the linkage mechanism 3. At the same time, it also simplifies the cleaning process, thereby reducing the difficulty of cleaning and maintenance.

[0090] In one embodiment, the baffle 6 is detachably mounted on the support base 1 so that the baffle 6 can be disassembled and installed for easier maintenance.

[0091] See Figures 3-6 In one embodiment, the waste collection device further includes:

[0092] The second guide mechanism 7 is disposed between the inclined part 11 and the sliding cover 4. The second guide mechanism 7 is used to guide the sliding cover 4 to slide, so that the sliding cover 4 can only slide up and down along a preset trajectory. This effectively restricts the sliding freedom of the sliding cover 4, thereby ensuring that the sliding cover 4 can only slide up and down smoothly and steadily along the predetermined trajectory, avoiding swaying and jamming, so that the sliding cover 4 can be reliably opened or closed.

[0093] See Figures 3-6 To further improve the sliding stability of the sliding cover 4, in one embodiment, the left and right sides of the sliding cover 4 are respectively connected to the inclined part 11 through a set of second guide mechanisms 7.

[0094] See Figures 3-6 In one embodiment, the second guide mechanism 7 includes:

[0095] A second guide member 71 is disposed on the inclined portion 11 and has a second guide groove 711 extending along the sliding direction of the sliding cover 4; and

[0096] The second roller 72 is rotatably mounted on the sliding cover 4 and rolls with the second guide groove 711. The sliding cover 4 is driven to slide by the second roller 72 rolling along the second guide groove 711. Rolling friction replaces sliding friction, which can reduce movement resistance, wear and operating noise, thereby making the sliding cover 4 move more smoothly and stably.

[0097] See Figures 3-6 In one embodiment, the waste collection device further includes:

[0098] Two sets of third rollers 8 are rotatably mounted on the sliding cover 4. The rotation center line of the third roller 8 is perpendicular to the rotation center line of the second roller 72. The two sets of third rollers 8 are spaced apart along the left and right direction of the sliding cover 4. Each set of third rollers 8 rolls in cooperation with the corresponding second guide component 71, forming a bidirectional constraint on the sliding cover 4. This effectively limits the left and right swaying of the sliding cover 4 during the sliding process, making the sliding cover 4 slide more smoothly and steadily. At the same time, the third rollers 8 roll along the second guide component 71, replacing sliding friction with rolling friction, which can reduce moving resistance, wear and operating noise, thus making the sliding cover 4 move more smoothly and steadily.

[0099] See Figures 1-3 In one embodiment, the waste collection device further includes:

[0100] The tabletop 9 is located on the top of the supporting base 1. The tabletop 9 is located directly above the inclined part 11 and forms an operating space with the inclined part 11. The operating space is used for users to throw garbage into the garbage disposal port 12. The tabletop 9 is used to place items.
