[0002] As people's living standards improve, their demands for comfort and hygiene in their homes are also increasing. Traditional trash cans require manual bagging, followed by manually squeezing out the air between the bag and the can body to ensure a proper seal. This process is cumbersome and easily gets hands dirty, failing to meet the convenience and hygiene requirements of modern living. Self-adsorption bagging trash cans, through their automatic adsorption function, expel the air between the bag and the can body, improving convenience and comfort in the home and significantly increasing the efficiency and ease of waste disposal.

[0003] However, current self-adhesive bagging trash cans still have some minor drawbacks. For example, most self-adhesive bagging trash cans on the market have a complex structure, making it inconvenient to change the trash bags, while electronic self-adhesive bagging trash cans are relatively expensive.

Detailed Implementation

[0024] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0025] like Figures 1 to 9 As shown, the self-adsorption bagged trash can provided by this utility model includes an outer cylinder 1 and an inner cylinder 2. The inner cylinder 2 is movably placed inside the outer cylinder 1. Several gas outlets 15 are opened in the lower part of the inner cylinder 2. A box body 3 is fixedly connected to the right side of the outer cylinder 1. The box body 3 is divided into an upper area and a lower area by a partition 4. The upper area is a storage area. A connecting hole is opened in the lower part of the right side of the outer cylinder 1. The lower part of the outer cylinder 1 is connected to the lower area through the connecting hole. An air extraction component is installed in the lower area. The air extraction assembly includes a base 5, which is fixedly connected to the bottom surface of the lower region of the housing 3. A piston cylinder 6 is fixedly connected to the center of the top surface of the base 5. A piston 7 is slidably connected inside the piston cylinder 6. A return spring 8 is fixedly connected between the bottom surface of the piston 7 and the bottom surface of the lower region of the housing 3. A foot pedal 9 is fixedly connected to the bottom front side of the piston 7. A foot pedal receiving frame 10 is fixedly connected to the front side of the piston cylinder 6 and the base 5. The foot pedal 9 slides up and down in the foot pedal receiving frame 10. A foot pedal extension hole is provided on the lower side of the housing 3. The front part of the foot pedal 9 extends out of the foot pedal extension hole. An exhaust pipe 11 is fixedly connected to the top of the piston cylinder 6. The inner cavity of the exhaust pipe 11 communicates with the inner cavity of the piston cylinder 6, allowing exhaust gas to pass through. At least one air inlet 12 is provided through the bottom surface of the cylinder 11. At least one exhaust plate 13 is provided inside the bottom surface of the exhaust cylinder 11. The exhaust plate 13 is located above the air inlet 12 and is rotatably connected to the bottom surface inside the exhaust cylinder 11. An exhaust port 14 is provided through the middle of the top surface of the exhaust cylinder 11. A baffle 20 is rotatably connected to the middle of the top surface of the exhaust cylinder 11 and is located above the exhaust port 14. A pressure cap 16 is fixedly connected to the middle of the top surface of the exhaust cylinder 11 and is located outside the baffle 20. A conduit 17 is fixedly connected to one side of the pressure cap 16. An exhaust hole 18 is provided in the lower area of ​​the box 3. The end of the conduit 17 away from the pressure cap 16 is connected to the exhaust hole 18.

[0026] The storage area can store garbage bags, so you don't need to go elsewhere to find them when you need to change them, which saves time and is more convenient.

[0027] Specifically, several gas outlets 15 are arranged in a ring at equal intervals in the lower part of the inner cylinder 2. The reason for placing several gas outlets 15 in the lower part of the inner cylinder 2 is that if the garbage bag is damaged, some liquid may flow into the inner cylinder 2. If the gas outlets 15 are designed at the bottom of the inner cylinder 2, this liquid will flow into the space between the inner cylinder 2 and the outer cylinder 1, and may further contaminate the air extraction components, causing a lot of trouble for the cleaning work.

[0028] When the foot pedal 9 is not pressed, the return spring 8 is in its natural state, and the top of the piston 7 is at the top of the piston cylinder 6. When the foot pedal 9 is pressed, the piston 7 moves downward inside the piston cylinder 6, and the return spring 8 is compressed.

[0029] The working principle of this utility model is as follows: After replacing the garbage bag in the inner cylinder 2, step on the foot pedal 9. The piston 7 moves downward in the piston cylinder 6, and the pressure in the piston cylinder 6 decreases. At this time, since the exhaust plate 13 can only open and close in one direction, the baffle 20 covers the exhaust port 14. The external gas pushes the exhaust plate 13 on the air inlet 12 to rotate, so that the air inlet 12 is in a ventilated state. The air between the garbage bag and the inner cylinder 2 is drawn into the lower area of ​​the box 3 from the gas outlet 15, and enters the space between the exhaust cylinder 11 and the piston cylinder 6 through the air inlet 12. When the pressure of the gas in the exhaust cylinder 11 and the piston cylinder 6 is equal to the external pressure, the exhaust plate 13 resets and covers the air inlet 12. When the foot is released from the foot pedal 9, the piston 7 returns to its original position under the action of the return spring 8. The gas pressure inside the exhaust pipe 11 and piston cylinder 6 is greater than the external air pressure. At this time, since the exhaust plate 13 can only open and close in one direction, the exhaust plate 13 covers the air inlet 12. The gas pushes the baffle 20 on the exhaust port 14 to rotate, so that the exhaust port 14 is in a venting state. The gas is discharged through the exhaust port 14, the conduit 17 and the exhaust hole 18. When the gas pressure inside the exhaust pipe 11 and piston cylinder 6 is equal to the external pressure, the baffle 20 returns to its original position and covers the exhaust port 14. If the air between the garbage bag and the inner cylinder 2 cannot be completely expelled in one foot pedal operation, the above operation is repeated until the air between the garbage bag and the inner cylinder 2 is completely expelled.

[0030] In one specific embodiment, a crossover ring 19 is fixedly connected to the top end of the inner cylinder 2. The inner cylinder 2 is movably placed inside the outer cylinder 1 via the crossover ring 19, and the crossover ring 19 is movably connected to the top end of the outer cylinder 1. The crossover ring 19 movably connects the inner cylinder 2 and the outer cylinder 1, facilitating operation and thus improving operational efficiency.

[0031] In one specific embodiment, rubber gaskets are installed at the contact edges between the inner cylinder 2 and the outer cylinder 1 to ensure the overall sealing of the device.

[0032] In one specific embodiment, ear seats are fixedly connected to both sides of the air inlet 12, and pins are fixedly installed on both sides of the exhaust plate 13, with the pins rotatably inserted into the ear seats. During adsorption and exhaust, gas enters from the air inlet 12, and the exhaust plate 13 rotates via the pins and ear seats. The shape of the baffle 20 is the same as that of the exhaust plate 13, and the same applies when the baffle 20 rotates.

[0033] In one specific embodiment, the piston cylinder 6 consists of two cylindrical bodies with different diameters, the bottom end of the larger diameter cylinder being fixedly connected to the top end of the smaller diameter cylinder; the piston 7 includes a piston rod and a piston plate, the top end of the piston rod being fixedly connected to the middle of the bottom surface of the piston plate; the diameter of the piston rod matches the inner diameter of the smaller diameter cylinder, and the diameter of the piston plate matches the inner diameter of the larger diameter cylinder. Here, "matching" means ensuring both smooth sliding of the piston 7 within the piston cylinder 6 and maintaining a sealed state between the piston cylinder 6 and the piston 7.

[0034] In one specific embodiment, the foot pedal 9 is T-shaped, and the size of the vertical part of the foot pedal 9 matches the size of the pedal protrusion hole, ensuring that the outside and inside of the device are separated.

[0035] In one specific embodiment, the rotatable side of both the baffle 20 and the exhaust plate 13 is configured as an inclined surface. By configuring them as inclined surfaces, the opening and closing angles of the baffle 20 and the exhaust plate 13 can be limited.

[0036] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
