[0024] The embodiments of the present invention will be further described below with reference to the accompanying drawings.

[0025] According to some embodiments of the present invention, with reference to Figures 1 to 11 The double-layered, separate trash can includes an outer cylinder 100, an inner cylinder 200, and a flip-top 300. The outer cylinder 100 is equipped with a drive assembly 110. The inner cylinder 200 is detachably installed within the inner cavity of the outer cylinder 100. The flip-top 300 is rotatably connected to the outer cylinder 100; rotating the flip-top 300 opens or closes the opening of the outer cylinder 100. The flip-top 300 has a disposal port 310, and a sealing assembly 400 is rotatably connected to the flip-top 300. The drive assembly 110 can drive the sealing assembly 400 to open or close the disposal port 310. When the flip-top 300 closes the opening of the outer cylinder 100, the disposal port 310 is located above the outer cylinder 100. When the disposal port 310 is opened, it communicates with the inner cavity of the inner cylinder 200.

[0026] Reference Figures 1 to 3 In daily use, the garbage bag is placed on the inner cylinder 200, the flip cover 300 is rotated to open the opening of the outer cylinder 100, the inner cylinder 200 is placed inside the outer cylinder 100, and then the flip cover 300 is rotated to close the opening of the outer cylinder 100. When garbage needs to be disposed of, the drive component 110 is activated, which drives the sealing component 400 to open the disposal port 310. The user throws garbage down into the inner cylinder 200 through the disposal port 310, and the drive component 110 then drives the sealing component 400 to seal the disposal port 310.

[0027] By setting a dispensing port 310 on the flip cover 300, the drive component 110 controls the opening and closing of the dispensing port 310 by controlling the sealing component 400, thereby avoiding frequent opening and closing of the flip cover 300.

[0028] When it's time to change the garbage bag, simply open the flip cover 300 and take out the inner cylinder 200 from the outer cylinder 100. It's simple and convenient, without having to swing the heavy outer cylinder 100. The outer cylinder 100 is usually made of sturdy and durable materials such as plastic, metal, or composite materials to provide structural stability, while the inner cylinder 200 can be made of lighter plastic material, thus reducing the daily handling load.

[0029] According to some embodiments of the present invention, with reference to Figures 3 to 7The sealing assembly 400 includes a first gear component 420 and a baffle 410. The first gear component 420 is rotatably connected to the flip cover 300, and the baffle 410 is fixedly connected to the first gear component 420. The outer cylinder 100 is provided with a second gear component 120, which is rotatably connected to the outer cylinder 100. The driving assembly 110 is used to drive the second gear component 120 to rotate.

[0030] Reference Figure 6 When the flip cover 300 is rotated clockwise to block the opening of the outer cylinder 100, the first gear component 420 and the second gear component 120 mesh together. At this time, the drive component 110 can drive the second gear component 120 to rotate, thereby driving the first gear component 420 to rotate, and then driving the baffle 410 to rotate to open or block the delivery port 310.

[0031] Reference Figure 6 When the flip cover 300 is rotated counterclockwise so that the flip cover 300 moves away from the opening of the outer cylinder 100 and thus opens the opening of the outer cylinder 100, the first gear component 420 and the second gear component 120 disengage from each other.

[0032] Preferred, refer to Figures 7 to 11 The drive assembly 110 includes a pedal 111, a connecting rod 112, a slider 114, and a return spring 113. The pedal 111 is elongated and extends in the front-to-back direction. The pedal 111 is located at the bottom of the outer cylinder 100. The middle part of the pedal 111 is rotatably connected to the outer cylinder 100. The front end of the pedal 111 extends forward out of the outer cylinder 100. The lower end of the connecting rod 112 is hinged to the rear end of the pedal 111. The upper end of the connecting rod 112 is connected to the slider 114. The slider 114 is slidably connected to the outer cylinder 100 in the up-down direction. The upper end of the return spring 113 is connected to the outer cylinder 100. The lower end of the return spring 113 is connected to the slider 114. The slider 114 is provided with a rack 115, which meshes with the second gear component 120.

[0033] Understandably, when the flip cover 300 blocks the opening of the outer cylinder 100, in the initial state, the baffle 410 blocks the dispensing port 310. When it is necessary to open the dispensing port 310, the user presses the front end of the pedal 111 downwards with their foot, causing the rear end of the pedal 111 to tilt upwards, thereby driving the connecting rod 112 and the slider 114 to move upwards. The upward movement of the slider 114 compresses the return spring 113. During the upward movement of the slider 114, the second gear component 120 rotates, thereby driving the first gear component 420 to rotate, and then driving the baffle 410 to rotate to open the dispensing port 310. When it is not necessary to open the dispensing port 310, the user leaves the pedal 111. Under the action of the return spring 113, the slider 114 moves downwards and drives the second gear component 120 to rotate, thereby driving the first gear component 420 to rotate, and then driving the baffle 410 to rotate to block the dispensing port 310.

[0034] Furthermore, refer to Figures 7 to 9 The first gear component 420 includes a first connecting gear 421 and a swing gear 422, both of which are rotatably connected to the flip cover 300. The first connecting gear 421 and the swing gear 422 are meshed together, and the baffle 410 is fixedly connected to the swing gear 422. When the flip cover 300 blocks the opening of the outer cylinder 100, the first connecting gear 421 and the second gear component 120 are meshed together.

[0035] Furthermore, refer to Figures 7 to 10 The second gear component 120 includes a plurality of second connecting gears 121 arranged at intervals in the vertical direction and meshing sequentially. The rack 115 is meshed with the second connecting gear 121 located at the bottom. When the flip cover 300 seals the opening of the outer cylinder 100, the first connecting gear 421 and the second connecting gear 121 located at the top are meshed.

[0036] It is understandable that as the slider 114 moves up and down, it drives the second connecting gear 121 at the bottom to rotate, thereby driving multiple second connecting gears 121 to rotate synchronously. Furthermore, the second connecting gear 121 at the top drives the first connecting gear 421 to rotate, which in turn drives the baffle 410 to rotate.

[0037] In another embodiment, a push rod motor and a photoelectric sensor are used instead of the pedal 111, connecting rod 112, and return spring 113. The push rod motor and the photoelectric sensor are electrically connected, and the push rod motor is used to push the slider 114 to move in the up-down direction. When the photoelectric sensor detects a human body approaching, the push rod motor pushes the slider 114 upward to open the dispensing port 310; when the photoelectric sensor detects a human body leaving, the push rod motor pushes the slider 114 downward to close the dispensing port 310.

[0038] Preferred, refer to Figures 7 to 9 The sealing assembly 400 has two parts, and the second gear component 120 has two parts. Each sealing assembly 400 corresponds to one of the two second gear components 120. Racks 115 are provided on both the left and right sides of the slider 114. The two second gear components 120 are located on the left and right sides of the slider 114, respectively, and are meshed with the two racks 115. The baffles 410 of the two sealing assemblies 400 are symmetrically arranged in the left-right direction. The two baffles 410 can rotate to move closer together to block the dispensing opening 310, or move away from each other to open the dispensing opening 310. The coordinated rotation of the two baffles 410 reduces the rotation range. Compared to a single baffle 410 requiring a larger rotation angle, the two baffles 410 can achieve the same opening size with smaller rotation angles. This allows for the design of a larger dispensing opening 310 while minimizing the rotation range of the baffles 410.

[0039] Preferred, refer to Figure 8 The flip cover 300 is provided with a fixed shaft 320. The first connecting gears 421 of the two sealing components 400 are located on the left and right sides of the fixed shaft 320 respectively. The swing gears 422 of the two sealing components 400 are both sleeved and rotatably connected to the fixed shaft 320.

[0040] According to some embodiments of the present invention, with reference to Figure 4 The flip cover 300 is provided with a limiting block 330, and the upper end face of the outer cylinder 100 is provided with a limiting groove 340. When the flip cover 300 blocks the opening of the outer cylinder 100, the limiting block 330 is inserted into the limiting groove 340, thereby cooperating to achieve precise positioning of the flip cover 300 and the outer cylinder 100, preventing the flip cover 300 from being misaligned or shaking, and ensuring the meshing accuracy of the first gear component 420 and the second gear component 120.

[0041] According to some embodiments of the present invention, with reference to Figure 5 The inner cylinder 200 has recessed sidewalls on both sides forming handle grooves 210. The outer cylinder 100 has notches 220 on its inner sidewalls on both sides. The flip cover 300 has two protrusions 360, and the two protrusions 360, the two handle grooves 210, and the two notches 220 correspond one-to-one. It can be understood that when the flip cover 300 seals the opening of the outer cylinder 100, the protrusions 360 insert into the notches 220, thus limiting movement and preventing the flip cover 300 from shaking. When the flip cover 300 is opened and the inner cylinder 200 needs to be lifted, the user can reach into the notches 220 and lift the inner cylinder 200 through the handle grooves 210.

[0042] According to some embodiments of the present invention, with reference to Figures 1 to 3 The outer peripheral wall of the flip cover 300 is provided with a handle 350; when the flip cover 300 blocks the opening of the outer cylinder 100, the handle 350 is located on the front side of the outer cylinder 100. The user can flip the flip cover 300 by holding the handle 350.

[0043] The working process of this embodiment includes: First, the user places the garbage bag onto the inner cylinder 200 and flips open the flap 300 via the handle 350, allowing the flap 300 to rotate around the outer cylinder 100. At this time, the limiting block 330 disengages from the limiting groove 340, and the protrusion 360 moves out of the notch 220. Next, the inner cylinder 200 is placed inside the outer cylinder 100, ensuring that the handle groove 210 of the inner cylinder 200 is aligned with the notch 220 of the outer cylinder 100. Then, the flap 300 is closed, sealing the opening of the outer cylinder 100. At this time, the limiting block 330 inserts into the limiting groove 340, and the protrusion 360 enters the notch 220. Simultaneously, the first connecting gear 421 on the flap 300 meshes with the uppermost second connecting gear 121 on the outer cylinder 100, and the baffle 410 of the sealing assembly 400 is in the state of sealing the disposal port 310.

[0044] When garbage needs to be disposed of, in the mechanical embodiment, the user steps on the front end of the pedal 111, which rotates around the central pivot point. The rear end of the pedal 111 pushes the slider 114 upward through the connecting rod 112, compressing the return spring 113. The racks 115 on both sides of the slider 114 drive the second connecting gears 121 at the bottom on both sides to rotate. The power is transmitted through the multi-stage second connecting gears 121 to the uppermost second connecting gear 121, which in turn drives the first connecting gear 421 and the swing gear 422 to rotate, causing the left and right symmetrical baffles 410 to move away from each other and opening the disposal port 310. After the user puts garbage into the disposal port 310, he releases the pedal 111, and the return spring 113 pushes the slider 114 downward. The racks 115 drive the gears to rotate in the opposite direction, causing the baffles 410 to move closer together and close the disposal port 310.

[0045] When the garbage bag needs to be replaced, the user opens the flip cover 300 through the handle 350, reaches in through the notch 220 of the outer cylinder 100 and the handle groove 210 to lift out the inner cylinder 200, puts the garbage bag back in after replacing it, and closes the flip cover 300.

[0046] Throughout the process, the outer cylinder 100 remains fixed, while only the inner cylinder 200 and the flip cover 300 move lightly. The small-range opening and closing of the dispensing port 310 reduces space occupation and collision risk, ensuring reliability and durability.
