Description

Technical Field

[0001] This application relates to the technical field of trash can products, specifically to a trash can. Background Technology

[0002] Trash cans are widely used containers for garbage collection. The structure of existing trash cans is generally a cylindrical structure with an opening at the top and a sealed bottom at the bottom. Then, the garbage bag is put on the trash can through the opening.

[0003] Currently, especially in small, cylindrical trash cans used in homes, air can exist between the trash bag and the inner wall of the trash can. During the process of fitting the trash bag, the bag is often pushed up by the air inside the can, making it difficult for it to fit snugly against the inner wall. This can easily lead to the trash bag bulging or not fully unfolding. This situation will affect the collection and storage of trash, especially kitchen waste, which is prone to leakage or overflow, making it inconvenient to recycle. Utility Model Content

[0004] To address the aforementioned shortcomings of the prior art, this application provides a trash can that, by setting an inner and outer bucket structure, generates negative pressure in the inner bucket during the process of the outer bucket fitting the inner bucket, thereby ensuring a good fit between the trash bag and the inner wall of the trash can.

[0005] To solve the above-mentioned technical problems, the technical solution adopted in this application is as follows: a trash can, the structure of which includes an outer barrel and an inner barrel, the inner barrel being used for fitting and fixing trash bags; the upper end of the outer barrel is provided with an opening, and a lid is provided at the opening and hinged thereto; the inner barrel is provided with an air hole near the lower end; the outer barrel is fitted and fitted onto the inner barrel.

[0006] By adopting the above structure, this application sets up a trash can with two bins: an outer bin and an inner bin. After the trash bag is placed on the inner bin, the outer bin with the lid is then placed on top of the inner bin. This process can generate a brief negative pressure inside the inner bin. Because the inner bin has air holes, under the combined action of the negative pressure and the air holes, the trash bag placed on the inner bin is squeezed and adheres to the inner wall of the inner bin, thereby unfolding the trash bag. Therefore, this specific trash can structure can effectively solve the problems of non-adhesive and incomplete unfolding of trash bags in the prior art.

[0007] Furthermore, the air vents are provided in multiple locations, and these multiple air vents are evenly distributed along the circumference of the inner bucket. With this structure, balanced air venting can be achieved in the circumference, so that the garbage bag can be effectively unfolded and fit snugly against the inner bucket at all positions.

[0008] Furthermore, after the outer barrel is fitted onto the inner barrel, the lower end of the outer barrel is higher than the lower end of the inner barrel. With this structure, after the two barrels are fitted together, a height difference is formed between their lower ends, which facilitates the airflow to be discharged from the air hole.

[0009] Furthermore, the inner barrel has a conical structure that is larger at the top and smaller at the bottom, while the outer barrel has a structure with equal diameter at the top and bottom. With this structure, when the two barrels are fitted together, a gap with a smaller top and a larger bottom is formed between the outer barrel and the inner barrel, which further facilitates the discharge of airflow from the vent.

[0010] Furthermore, the open end of the outer barrel is provided with a radially inwardly extending retaining ring, and a support block is provided on the inner side of the retaining ring. The support block is used to abut against the upper end face of the inner barrel. With this structure, after the outer barrel is fitted onto the inner barrel, the outer barrel can be supported by the support block, so that the height of its lower end face is higher than the height of the lower end face of the inner barrel, forming a height difference.

[0011] Furthermore, the retaining ring is provided with a guide surface that is inclined towards the inner barrel, and the inner diameter of the guide surface is smaller than the inner diameter of the opening at the upper end of the inner barrel; with this structure, when garbage is thrown, it can be ensured that all garbage enters the inner barrel through the guide surface.

[0012] Furthermore, the lid and the outer barrel are rotatably connected by a hinge, and a torsion spring is provided on the hinge. The torsion spring is used to provide the lid with a torque relative to the outer barrel to open. This structure facilitates the opening and closing of the lid and the outer barrel.

[0013] Furthermore, a snap-fit ​​structure is provided between the lid and the outer barrel body. The snap-fit ​​structure is used to fasten the lid and the outer barrel body. With this structure, when negative pressure is required, the torsion of the torsion spring is overcome to close the lid onto the outer barrel body. The two are fastened together by the snap-fit ​​structure, and then the whole thing is fitted onto the inner barrel body to realize the unfolding and fitting of the garbage bag.

[0014] Furthermore, the buckle structure includes a buckle block disposed on the bottom surface of the lid and a buckle hook disposed on the outer barrel. When the lid is closed on the outer barrel, the buckle block engages with the buckle hook. With this structure, the lid can close to the outer barrel after overcoming the torsion of the torsion spring, at which point the outer barrel can be placed on the inner barrel to achieve a negative pressure effect.

[0024] As attached Figure 1-6As shown, this application discloses a type of trash can. The trash can's structure includes an outer barrel 1 and an inner barrel 2. The inner barrel 2 is used to fit and fix trash bags. The upper end of the outer barrel 1 is provided with an opening, and a lid 3 is provided at the opening and hinged thereto. The inner barrel 2 has an air hole 201 near its lower end. The outer barrel 1 covers and fits onto the inner barrel 2. Specifically, the outer barrel 1 of this application is a cylindrical structure that runs vertically through the inner barrel. Its upper end is an opening for setting and closing the lid 3, and its lower end is a fitting opening for fitting the inner barrel 2. The air hole 201 of this application is provided on the barrel wall of the inner barrel 2 and runs through the inner barrel 2 in the thickness direction to realize the flow of air inside and outside the inner barrel 2.

[0025] By adopting the above structure, this application sets up a trash can with two bins: an outer bin and an inner bin. After the trash bag is placed on the inner bin, the outer bin with the lid is then placed on top of the inner bin. This process can generate a brief negative pressure inside the inner bin. Because the inner bin has air holes, under the combined action of the negative pressure and the air holes, the trash bag placed on the inner bin is squeezed and adheres to the inner wall of the inner bin, thereby unfolding the trash bag. Therefore, this specific trash can structure can effectively solve the problems of non-adhesive and incomplete unfolding of trash bags in the prior art.

[0026] As attached Figure 2 , Figure 4 and Figure 5 As shown, the air holes 201 described in this application are provided in multiple ways, and the multiple air holes 201 are evenly distributed along the circumference of the inner barrel 2; that is, the multiple air holes 201 are arranged in a circumferential ring along the barrel wall of the inner barrel 2; with this structure, balanced air exhaust can be achieved in the circumferential direction, so that the garbage bag can be effectively unfolded and fit against the inner barrel at all positions; the air holes in this application are not limited to the above-mentioned ring, and multiple rings of air holes can also be provided.

[0027] As attached Figure 2 and Figure 4 As shown, after the outer barrel 1 is fitted onto the inner barrel 2, the lower end face of the outer barrel 1 is higher than the lower end face of the inner barrel 2. With this structure, after the two barrels are fitted together, a height difference is formed between their lower ends, which facilitates the airflow from the vent. Specifically, after the two are fitted together, the lower end face of the outer barrel 1 can be exactly flush with the position of the vent 201, or slightly higher or slightly lower than the position of the vent 201, thereby ensuring that when the inner barrel 2 generates negative pressure, the gas on the inner wall flows out smoothly, achieving effective adhesion and unfolding of the garbage bag to the inner wall of the inner barrel 2.

[0028] As attached Figure 2 and Figure 4 as well as Figure 5 As shown, the inner barrel 2 described in this application has a conical structure that is larger at the top and smaller at the bottom, while the outer barrel 1 has a structure with equal diameters at the top and bottom. That is, the diameter of the inner barrel 2 gradually decreases from the upper opening end to the lower bottom end, while the outer barrel 1 has a straight cylindrical structure with equal diameters at the top and bottom. With this structure, when the two barrels are fitted together, a gap with a smaller top and a larger bottom is formed between the outer barrel and the inner barrel. The generation of this gap can further facilitate the discharge of airflow in the vent.

[0029] As attached Figure 1 , Figure 2 , Figures 4-6 As shown, the outer barrel 1 of this application has a radially inwardly extending retaining ring 101 at its open end. A support block 102 is provided on the inner side of the retaining ring 101. The support block 102 is used to abut against the upper end face of the inner barrel 2. Specifically, the support block 102 is located between the retaining ring and the inner wall of the outer barrel 1. When the outer barrel 1 is fitted onto the inner barrel 2, the support block 102 can support the outer barrel 1, making its lower end face higher than the lower end face of the inner barrel 2. The height difference between the two facilitates the discharge of air from the air hole 201 in the inner barrel 2 under negative pressure.

[0030] As attached Figure 1 , Figure 5 and Figure 6 As shown, the retaining ring 101 described in this application is provided with a guide surface 103 that is inclined towards the inner barrel 2, and the inner diameter of the guide surface 103 is smaller than the inner diameter of the upper opening of the inner barrel 2; that is, the guide surface 103 extends into the opening of the inner barrel 2; with this structure, when garbage is thrown, it can be ensured that all garbage enters the inner barrel 2 through the guide surface 103.

[0031] As attached Figure 1 , Figure 2 and Figure 3 As shown, the bucket lid 3 and the outer bucket body 1 are rotatably connected by a hinge 4. A torsion spring 5 is provided on the hinge 4, which provides the bucket lid 3 with a torque relative to the outer bucket body 1 for opening. Specifically, the hinge 4 of this application is a rotating shaft that passes through the rotating holes on both the bucket lid 3 and the outer bucket body 1, realizing the rotatable connection between the bucket lid 3 and the outer bucket body 1. The torsion spring 5 is fitted at both ends of the hinge 4, which can fix the hinge 4 in the rotating hole and also provide the torque for the bucket lid 3 to automatically spring open after it is opened. With this structure, the opening and closing of the bucket lid 3 and the outer bucket body 1 can be convenient.

[0032] As attached Figure 1-5As shown, a snap-fit ​​structure is also provided between the lid 3 and the outer barrel 1 described in this application. The snap-fit ​​structure is used for fastening between the lid 3 and the outer barrel 1. The snap-fit ​​structure can be set on the radially opposite side of the hinge structure to facilitate the lid 3 and the outer barrel 1 to be closed. When negative pressure is required, the lid 3 is closed onto the outer barrel 1 to overcome the torsion of the torsion spring 5. The two are fastened together by the snap-fit ​​structure and then the whole is fitted onto the inner barrel 1 to realize the unfolding and fitting operation of the garbage bag.

[0033] As attached Figure 1-5 As shown, the snap-fit ​​structure described in this application includes a snap-fit ​​block 301 disposed on the bottom surface of the lid 3 and a snap-fit ​​hook 104 disposed on the outer barrel 1. When the lid is closed onto the outer barrel, the snap-fit ​​block 301 is engaged in the snap-fit ​​hook. Specifically, the snap-fit ​​block 301 includes a flat portion connected to the bottom surface of the lid 3 and a protrusion for engaging with the snap-fit ​​hook 104. The corresponding snap-fit ​​hook 104 includes a connecting portion connected to the outer barrel 1 and a fastening portion protruding from the retaining ring 101. The protrusion protrudes in the width direction, and the corresponding fastening portion is provided with an elastic snap-fit ​​structure. When the protrusion is engaged into the elastic snap-fit ​​portion, it elastically deforms outward and then resets to fasten the protrusion. With this structure, the lid can be closed onto the outer barrel after overcoming the torsion of the torsion spring. At this time, the outer barrel can be placed on the inner barrel to achieve a negative pressure effect.

[0034] The aforementioned trash can of this application, for the first time, features an air hole 201 on the inner barrel 2. When the outer barrel 1, after the lid 3 is closed, is fitted onto the inner barrel 2, a negative pressure effect is generated within the inner barrel 2. At this time, the trash bag unfolds under the negative pressure, and the air in the inner barrel 2 is also squeezed out from the air hole 201 under the negative pressure. This allows the trash bag to better fit against the inner wall of the inner barrel 2, completing the unfolding and fitting of the trash bag. When needed, the buckle structure can be manually unlocked, and the lid 3 pops open under the torque of the torsion spring 5, revealing the opening of the inner barrel 2 for trash collection and storage. Alternatively, after the trash bag has unfolded and fitted, the outer barrel 2 can be removed entirely from the inner barrel 2, allowing for trash collection and storage directly using the inner barrel 2.
