Description

Technical Field

[0001] This application relates to the field of trash cans, and in particular to an absorbent trash can. Background Technology

[0002] Trash cans are mainly used to hold trash, and trash bags are usually placed inside them. These trash bags are generally rolled up. Each time you need to put a trash bag inside a trash can, you need to open the trash bag first, and while putting it inside the trash can, you also need to reach into the trash can to make the trash bag fit roughly against the inner wall of the trash can.

[0003] Regarding the aforementioned technologies, the inventor believes that this method of using garbage bags is not convenient enough, and the garbage bag cannot fit well against the inner wall of the garbage can. If the garbage bag does not contact the bottom of the garbage can, when throwing away garbage later, if the garbage bag is suddenly subjected to external force, the opening of the garbage bag and the opening of the garbage can may loosen if they are not tightened enough, thus requiring the user to tighten them again. Therefore, the usage effect is not good. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of the prior art and provide an adsorption trash can that allows trash bags to be easily and effectively adsorbed onto the inner wall of the trash can.

[0005] To achieve the above objectives, this application adopts the following technical solution:

[0006] An adsorption-type trash can includes a cylindrical body with openings at the top and bottom, a support plate slidably disposed inside the cylindrical body, a guide groove disposed along the axis of the cylindrical body, the support plate being located in the guide groove, and a limiting member for restricting the sliding of the support plate relative to the cylindrical body.

[0007] Preferably, the support plate has a guide block located within the guide groove, and the limiting member is located at the end of the guide groove.

[0008] Preferably, the opening of the cylinder is also provided with a vent hole.

[0009] Preferably, the vent hole at the opening of the cylinder is provided with an upper anti-leakage groove, and an upper anti-leakage ring is slidably disposed in the upper anti-leakage groove.

[0010] Preferably, the vent hole at the lower opening of the cylinder is provided with a lower anti-leakage groove, and a lower anti-leakage ring is slidably disposed in the lower anti-leakage groove.

[0011] Preferably, an extension ring is provided at the opening of the cylinder, and the cylinder is also provided with a clamping plate, with a clamping groove formed between the extension ring and the clamping plate.

[0012] Preferably, the clamping plate is arc-shaped, and the clamping groove has an flared end and a constricted end.

[0013] In summary, this utility model has the following beneficial technical effects:

[0014] Place the garbage bag onto the bin. Utilize the negative pressure created by the downward sliding of the support plate to make the bottom of the garbage bag and the support plate point downwards together, and also to make the side wall of the garbage bag adhere to the inner wall of the bin. This facilitates the bag adhering well to the inner wall of the garbage bin, improving the effectiveness of the garbage bag placement. Attached Figure Description

[0020] The following is in conjunction with the appendix Figure 1 -Appendix Figure 3 This application will be described in further detail.

[0021] This application discloses an adsorption-type trash can.

[0022] An absorbent trash can includes a cylindrical body 1 with an upper opening and a lower opening, both openings being the same. An extension ring 11 and a clamping plate 12 are provided at both the upper and lower openings, forming a clamping groove 13 between the extension ring 11 and the clamping plate 12. Since the opening of a trash bag is generally larger than the trash can's opening, after the trash bag is placed inside, the excess opening of the trash bag is closed and clamped within the clamping groove 13, aligning the opening of the trash bag with the opening of the trash can. The clamping plate 12 is arc-shaped, and the clamping groove 13 has a flared end 131 and a constricted end 132. The two ends of the clamping groove 13 are flared 131, and the middle is constricted 132. The flared end 131 facilitates the insertion of the trash bag, while the constricted end 132 helps to restrain the trash bag. This trash can is mainly suitable for trash bags without loops.

[0023] A support plate 2 is slidably disposed inside the cylinder 1, and the size of the support plate 2 is consistent with the inner diameter of the cylinder 1. The cylinder 1 is also provided with a guide groove 3 arranged along the axis of the cylinder 1. The support plate 2 has a guide block 21, which is located in the support groove. The guide groove 3 can guide the guide block 21, so that the support plate 2 can slide along the length of the cylinder 1.

[0024] The cylinder 1 is also provided with a limiting member 31 to restrict the sliding of the support plate 2 relative to the cylinder 1. The limiting member 31 is located at the end of the guide groove 3, that is, at the upper and lower ends of the guide groove 3. When the support plate 2 moves to the lower end of the guide groove 3, it will be stopped by the limiting member 31. It should be noted that as the cylinder 1 is rotated, the upper and lower ends of the guide groove 3 will also be reversed. After the cylinder 1 is rotated, the support plate 2, which was originally stopped by the limiting member 31 at the lower end of the guide groove 3, will be stopped by the limiting member 31 at the upper end of the guide groove 3. The upper opening and lower opening of the cylinder 1 are also provided with vent holes 4. The vent hole 4 at the upper opening of the cylinder 1 is provided with an upper anti-vent groove 5. An upper anti-vent ring 51 is slidably arranged in the upper anti-vent groove 5. The upper anti-vent ring 51 can block the vent hole 4 at the upper opening of the cylinder 1. The vent hole 4 at the lower opening of the cylinder 1 is provided with a lower anti-vent groove 6, and a lower anti-vent ring 61 is slidably disposed in the lower anti-vent groove 6. The lower anti-vent ring 61 can block the vent hole 4 at the lower opening of the cylinder 1.

[0025] Regardless of whether it's the upper anti-vent ring 51 or the lower anti-vent ring 61, as the cylinder 1 rotates, the upper anti-vent ring 51 or the lower anti-vent ring 61, which is positioned higher, will block the vent hole 4. The upper anti-vent ring 51 or the lower anti-vent ring 61, which is positioned lower, will not block the vent hole 4.

[0026] The implementation principle of this embodiment is as follows: The initial position of the support plate 2 is at the opening below the cylinder 1. When a new trash can needs to be placed, the cylinder 1 is rotated 180° so that the support plate 2 is located at the opening above the cylinder 1. The trash bag is opened and the opening of the trash bag is placed over the opening above the cylinder 1. The bottom of the trash bag will press against the support plate 2. Then, the support plate 2 is pushed. Since the vent hole 4 at the opening above the cylinder 1 is blocked, a negative pressure area is formed between the support plate 2 and the bottom of the trash bag during the downward movement of the support plate 2. This can drive the bottom of the trash bag to move downward as well. The side wall of the trash bag will stick to the inner side wall of the trash can. The vent hole 4 at the opening below the cylinder 1 is not blocked, and excess air below the support plate 2 can be easily discharged, which can increase the falling speed of the support plate 2. After the support plate 2 falls freely, it will be clamped by the limiting member 31, making the support plate 2 less prone to loosening.

[0027] The above are all preferred embodiments of this application and are not intended to limit the scope of protection of this application. Therefore, based on the technical solution of this utility model, those skilled in the art can propose various interchangeable structural methods and implementation methods without changing the essential spirit of this utility model. Therefore, the above specific embodiments and accompanying drawings are merely illustrative descriptions of the technical solution of this utility model and should not be considered as the entirety of this utility model or as a limitation or restriction on the technical solution of this utility model. Therefore, all equivalent changes made according to the structure, shape, and principle of this application should be covered within the scope of protection of this application.
