Description

Technical Field

[0001] The utility model belongs to the technical field of daily necessities and relates to a trash can. Background Art

[0002] A trash can, also known as a waste bin or trash can, refers to a container for storing trash. In order to keep the trash can clean, people usually put a trash bag inside the trash can when using it. The trash bag is a soft, thin bag made of plastic. In addition, the trash bag is initially in a rolled and folded state. When using it, the user first unfolds a single trash bag and places it inside the trash can, then turns the bag mouth of the trash bag outward and fixes it on the mouth of the trash can. Then the user needs to blow air into the trash bag or put his hand into the trash bag to tidy it up so that the trash bag can be unfolded for the convenience of the user to put in the trash. If the trash bag is to be close to the inner wall of the trash can, the user needs to constantly tidy it up by hand. This process is troublesome and takes a long time, which brings many inconveniences to the user and greatly reduces the user experience.

[0003] In order to solve this problem, those skilled in the art have also made some improvements. For example, a Chinese patent document discloses a trash can that can fix a trash bag (application number: 202020504500.X), which includes a trash can body, and an exhaust device for exhausting the air between the trash bag and the trash can body is installed on the outer peripheral surface of the trash can body; the exhaust device consists of an air cylinder, a piston, a connecting rod and a manual rod; the piston is air-tightly and slidingly arranged in the air cylinder, the manual rod is rotatably hinged on the support frame of the air cylinder, the upper end of the connecting rod is connected to the short back of the manual rod, and the lower end of the connecting rod is connected to the piston, and the bottom of the air cylinder is provided with a connecting nozzle connected to the exhaust pipe; an exhaust hole is formed on the piston, and a diaphragm is attached to the upper surface of the piston to cooperate with the piston to form a one-way air valve.

[0004] Although the above-mentioned trash can that can fix the trash bag can assist in unfolding the trash bag, installing an outwardly protruding exhaust device on the outer peripheral surface of the trash can body not only affects the aesthetics of the trash can, is not conducive to the packaging, storage and transportation of the trash can, but also increases the manufacturing and use costs of the trash can. In addition, when exhausting the air, the user also needs to bend over and pull the manual lever up and down with force, which is inconvenient to operate. Summary of the invention

[0005] The purpose of the utility model is to solve the above problems in the existing technology and propose a trash can. The technical problem to be solved by the utility model is how to spread the trash bag flat and spread it inside the trash can more conveniently and efficiently.

[0006] The purpose of the utility model can be achieved through the following technical solutions:

[0007] A trash can comprises a cylindrical barrel body and a barrel cover, wherein both ends of the barrel body are open and the barrel cover is movably covered on the top of the barrel body. The trash can is characterized in that a bottom cover is connected to the bottom of the barrel body, and an exhaust gap is formed between the barrel body and the bottom cover to connect the inside of the barrel body with the outside.

[0008] Different from the prior art, the present trash can is cleverly connected with a bottom cover at the bottom of the barrel body, and an exhaust gap connecting the inside of the barrel body and the outside is formed between the barrel body and the bottom cover, so that the barrel body and the bottom cover are kept connected and the exhaust gap is formed. When the present trash can is used in conjunction with a garbage bag, the user only needs to put the garbage bag on the barrel body, and then close the cylindrical barrel cover on the barrel body. As the barrel cover is closed, the air in the barrel cover is pressed into the garbage bag in the barrel body, and the garbage bag can automatically expand and unfold after being inflated. The air between the garbage bag and the inner wall of the barrel body and between the garbage bag and the inner wall of the bottom cover is discharged from the trash can through the exhaust gap between the barrel body and the bottom cover during the expansion and unfolding of the garbage bag, so as to realize the automatic and complete unfolding of the garbage bag, so that the garbage bag can be conveniently and efficiently spread out inside the trash can without relying on user assistance, thereby improving the user experience.

[0009] In addition, the present trash can has a structure in which an exhaust gap is provided between the barrel body and the bottom cover, thereby eliminating the need to drill holes in the barrel body or the bottom cover to open an exhaust port. The method of opening the exhaust port will reduce the structural strength of the barrel body or the bottom cover itself at the opening, while providing the above-mentioned exhaust gap between the barrel body and the bottom cover will not affect the structural strength of the barrel body and the bottom cover themselves. At the same time, the exhaust gap can be arranged to be a structure extending and distributed along the circumference of the barrel body, so that the air between the garbage bag and the inner wall of the barrel body and between the garbage bag and the inner wall of the bottom cover can be discharged from all directions, resulting in a good exhaust effect. At the same time, the present trash can has a simple structure, no obvious convex parts as the whole, and a beautiful shape. It can also be conveniently packaged, stored and transported, which is conducive to promotion and application.

[0010] In the above-mentioned trash can, the bottom cover has a supporting part, and the bottom of the barrel body is connected to the supporting part, and there is a spacing between the bottom end of the barrel body and the inner bottom wall of the bottom cover, and between the outer wall of the barrel body and the inner side wall of the bottom cover, so that the exhaust gap is formed between the barrel body and the bottom cover. By setting the supporting part, on the one hand, it can play the role of reinforcing ribs, thereby enhancing the structural strength of the bottom cover itself, and on the other hand, by connecting the bottom of the barrel body to the supporting part, the bottom of the barrel body and the top of the bottom cover and the side wall of the bottom cover can be staggered, so that there is a spacing between the bottom end of the barrel body and the inner bottom wall of the bottom cover, and between the outer wall of the barrel body and the inner side wall of the bottom cover, so that the exhaust gap is formed between the barrel body and the bottom cover, the design is ingenious, the structure is simple, and at the same time, the exhaust gap of the above structure can be set to a structure extending and distributed along the circumference of the barrel body, so that the air between the garbage bag and the inner wall of the barrel body and the garbage bag and the inner wall of the bottom cover can be discharged from all directions, and the exhaust effect is good.

[0011] In the above-mentioned trash can, the bottom diameter of the barrel body is smaller than the top diameter of the bottom cover, the supporting part is arranged on the inner side wall of the bottom cover, the supporting part has a plug-in slot, and the bottom edge of the barrel body is plugged into the plug-in slot. By arranging the supporting part on the inner side wall of the bottom cover, the supporting part is hidden in the bottom cover and is not exposed. At the same time, the bottom diameter of the barrel body is smaller than the top diameter of the bottom cover, so that the size of the bottom cover is larger than the size of the barrel body. The trash can as a whole has a small upper and large lower structure, which is not only more stable in structure, but also more beautiful in shape. Furthermore, the bottom edge of the barrel body is plugged into the plug-in slot of the supporting part, so that the barrel body and the bottom cover are easy to disassemble and assemble, and can be repeatedly disassembled and assembled without damaging the structure of the barrel body and the supporting part itself, thereby ensuring the convenience of assembly of the trash can.

[0012] In the above-mentioned trash can, there are multiple supporting parts, and the multiple supporting parts are arranged along the circumference of the bottom cover. The supporting parts are in the form of sheets and arranged vertically. The supporting parts are arranged in the form of sheets and arranged vertically, which can minimize the influence of the supporting parts on the partition of the exhaust gap and the blocking effect on the exhaust. By arranging multiple supporting parts along the circumference of the bottom cover, the bottom of the barrel body can be better balanced when connected to the supporting parts, and the structure is more reasonable, which can avoid the barrel body from tilting to one side, and can also make the size of the exhaust gap between the barrel body and the bottom cover stable, ensuring a better exhaust effect.

[0013] In the above-mentioned trash can, the bucket cover is sleeved on the outer side of the bucket body, and the bottom of the bucket cover has a flange portion. When the bucket cover is covered on the top of the bucket body, the flange portion abuts against the top edge of the bottom cover and closes the exhaust gap. By arranging the flange portion that can abut against the top edge of the bottom cover at the bottom of the bucket cover, on the one hand, when the bucket cover is covered on the top of the bucket body, the bucket cover and the bottom cover can fit tightly together, making the trash can look more beautiful; on the other hand, the exhaust gap only works before the bucket cover is completely covered, that is, before the bucket cover is completely covered on the bottom cover, the exhaust gap is always connected to the inside and outside of the bucket body. In this process, the automatic full expansion of the garbage bag is sufficient to be achieved, and after the bucket cover is completely covered, the exhaust gap is closed, so that the odor of the garbage in the bucket body cannot be emitted from the bucket body to the outside, thereby ensuring the freshness of the indoor air, and then more conveniently and efficiently spreading the garbage bag flat and expanding it inside the trash can while improving the user's experience.

[0014] In the above-mentioned trash can, the barrel body is provided with a raised portion, and the raised portion and the bottom cover are abutted and matched up and down to form the exhaust gap between the barrel body and the bottom cover. By providing the raised portion, the barrel body can be lifted as a whole relative to the bottom cover to form the exhaust gap between the barrel body and the bottom cover. The design is ingenious and the structure is simple. In addition, the raised portion can act as a reinforcing rib, thereby increasing the structural strength of the barrel body itself.

[0015] In the above-mentioned trash can, the bottom of the barrel body has an upper step portion, and the raised portion is arranged on the inner side of the barrel body and located on the upper step portion. By setting the upper step portion, on the one hand, it can be used for the bottom of the barrel cover to abut against; on the other hand, it can enhance the structural strength of the barrel body at this location to better bear pressure and force, thereby facilitating the setting of the raised portion at this location; finally, the upper step portion can cover the raised portion and the connection between the barrel body and the bottom cover, making the trash can look more beautiful as a whole. At the same time, the whole has no protruding parts, which can be convenient for packaging, storage and transportation, and is conducive to promotion and application.

[0016] In the above-mentioned trash can, there are multiple raised parts, and the multiple raised parts are arranged along the circumference of the barrel body. By arranging multiple raised parts along the circumference of the barrel body, the barrel body can be better balanced when it is lifted relative to the bottom cover as a whole, and the structure is more reasonable, avoiding the barrel body from tilting to one side, making the size of the exhaust gap between the barrel body and the bottom cover stable, and ensuring a better exhaust effect.

[0017] In the above-mentioned trash can, the barrel body has a plurality of protruding clamping parts, and the bottom cover has a protruding receiving part corresponding to each clamping part and engaging with the clamping part. By providing the clamping part on the barrel body and the matching receiving part on the bottom cover, it is convenient to disassemble and assemble the barrel body and the bottom cover, and it is also convenient to process and manufacture the barrel body and the bottom cover.

[0018] In the above-mentioned trash can, several clamping parts are distributed along the circumference of the barrel body, and several raised parts are divided into several groups. The raised parts are in the form of sheets and arranged vertically, and each group of raised parts is located above each clamping part. The raised parts are arranged in the form of sheets and arranged vertically, which can minimize the blocking effect of the raised parts on the exhaust. Since the thickness of a single raised part is relatively thin, by dividing the multiple raised parts into several groups, a combined force can be formed on the raised parts, thereby better supporting the barrel body to lift it relative to the bottom cover. In addition, it is preferred to arrange each group of raised parts in a one-to-one correspondence with each clamping part, so that the structure affecting the exhaust is arranged at the same position, thereby minimizing the blocking effect of the necessary structure on the exhaust and ensuring the exhaust effect of the exhaust gap; it is preferred to evenly distribute several clamping parts along the circumference of the barrel body, so that the structure is more reasonable, so that the barrel body and the bottom cover can be more stable after being connected.

[0019] In the above-mentioned trash can, the top and bottom of the receiving part are respectively against the raised part and the clamping part, so that the receiving part and the clamping part are engaged with each other. The above-mentioned structure enables the clamping part of the barrel body and the receiving part of the bottom cover to be clamped and connected, and the part where the receiving part and the clamping part are clamped is clamped between the raised part and the clamping part, thereby further enhancing the stability of the barrel body and the bottom cover after being connected.

[0020] In the above-mentioned trash can, the upper surface of the clamping part is inclined from high to low from outside to inside, and its lower surface is inclined towards the upper surface; the upper surface of the receiving part is inclined from low to high from outside to inside, and its lower surface is horizontally arranged. When the barrel body and the bottom cover are snap-connected, the upper surface of the receiving part and the lower surface of the snap-connecting part abut against each other until the two pass over each other. The upper surface of the receiving part is set to be inclined from low to high from the outside to the inside, and the lower surface of the snap-connecting part is set to be inclined from low to high from the outside to the inside, which is conducive to the two passing over each other, thereby facilitating the snap-connection of the barrel body and the bottom cover; at the same time, after the barrel body and the bottom cover are connected, the lower surface of the receiving part abuts against the upper surface of the snap-connecting part, and the lower surface of the receiving part is set horizontally, which can have a certain hindering effect on the separation of the two. The user needs to exert a certain degree of force to separate the two, so that the barrel body and the bottom cover are more stable after the connection, and either component can be replaced after the separation of the two, so that the other component can be reused.

[0021] In the above-mentioned trash can, the upper step portion extends along the circumference of the barrel body, the upper step portion is enclosed on the outside of the bottom cover, the barrel cover is sleeved on the outside of the barrel body, and the bottom of the barrel cover abuts against the upper step portion, the top of the bottom cover has a lower step portion, the lower step portion is inclined from low to high from the outside to the inside, and the lower step portion is located below the receiving portion, and the lower step portion and the clamping portion are arranged opposite to each other up and down. The upper step portion of the above-mentioned structure can cover the raised portion and the connection between the barrel body and the bottom cover, and the bottom of the barrel cover abuts against the upper step portion. On the one hand, the closing state of the barrel cover is more stable to prevent the barrel cover from shaking randomly after closing, and on the other hand, the trash can looks more beautiful as a whole. At the same time, the trash can as a whole has no protruding parts, beautiful shape, and can be conveniently packaged, stored and transported, which is conducive to promotion and application. At the same time, by arranging the upper step portion to be a structure enclosed on the outer side of the bottom cover, the exhaust gap is made into an "N" shape, which can reduce the emission of garbage odor in the trash can while ensuring the exhaust effect; in addition, by arranging the lower step portion to be inclined from low to high from the outside to the inside, the lower step portion can guide the exhaust on the one hand, and on the other hand, the exhaust gap is made into a structure that is small inside and large outside, so that the air flows to the outside faster, so that the lower step portion can guide the air exhausted in the trash can to be better discharged to the outside.

[0022] In the above-mentioned trash can, the lid is also provided with an openable lid, and the top of the barrel body is in an inwardly bent arc shape. By providing an openable lid on the lid, the lid can be opened to facilitate users to put in garbage, and when the lid is closed, the upper end of the lid can be closed with only the end opening left, so that the air in the lid can be pressed into the barrel body, and the smell of garbage in the trash can can be blocked; at the same time, by making the top of the barrel body in an inwardly bent arc shape, on the one hand, the lid can be prevented from colliding with the barrel body when the lid is closed, and on the other hand, the garbage bag can be better folded and put on the barrel body, and the outer wall of the barrel body and the inner wall of the lid can press and fix the folded part of the garbage bag, so as to prevent the garbage bag from being brought into the trash can by the discarded garbage.

[0023] Compared with the prior art, the advantage of this trash can is that when this trash can is used with a garbage bag, the user only needs to put the garbage bag on the barrel body, and then close the lid on the barrel body. As the lid is closed, the air in the lid is pressed into the garbage bag in the barrel body, and the garbage bag can automatically expand and unfold after being inflated. The air between the garbage bag and the inner wall of the barrel body and between the garbage bag and the inner wall of the bottom cover is discharged from the trash can through the exhaust gap between the barrel body and the bottom cover during the expansion and unfolding of the garbage bag, thereby achieving full unfolding of the garbage bag, so that the garbage bag can be conveniently and efficiently spread out inside the trash can without relying on user assistance, thereby improving the user's experience. At the same time, setting the above-mentioned exhaust gap between the barrel body and the bottom cover does not affect the structural strength of the barrel body and the bottom cover themselves. This trash can has a simple structure, no convex parts as a whole, and a beautiful shape. It can be conveniently packaged, stored and transported, which is conducive to popularization and application. BRIEF DESCRIPTION OF THE DRAWINGS
