[0001] The present application relates to a garbage can, in particular to a garbage can facilitating bagging. BACKGROUND
[0002] In daily life, garbage cans are indispensable. There are various types of garbage cans on the market, but there are still some problems.

In order to solve these problems, some attempts have been made in the industry, but the results are not ideal. For example, some garbage cans use complex mechanical structures to open the garbage bag, but the cost is high and the garbage can is prone to failure.
[0003] Therefore, there is an urgent need for a new garbage can design that is simple in structure and can easily open a garbage bag. CONTENT OF THE INVENTION

[0034] The present application will be described below in conjunction with the drawings and specific embodiments:
[0035] As Figures 1-4The application discloses a garbage can, which comprises an inner barrel 1 and an outer barrel 3 in a nested form. The inner barrel 1 comprises an inner cavity with an upper opening, which serves as a main storage space and is used for containing garbage after a garbage bag is laid. A pressing ring 2 is used for tightly pressing the bag opening of the garbage bag at the upper opening of the inner barrel 1, so that a first sealed cavity is formed between the garbage bag and the inner barrel 1. The shape of the pressing ring 2 is annular and is adapted to the shape of the barrel opening of the inner barrel 1. The cross-sectional shape of the pressing ring 2 generally comprises a reverse U-shaped part. The barrel wall at the barrel opening of the inner barrel 1 and the bag opening of the garbage bag can be clamped in the reverse U-shaped part of the pressing ring 2. Therefore, the distance between the two sides of the reverse U-shaped part of the pressing ring 2 is generally smaller than the thickness of the barrel wall at the barrel opening of the inner barrel 1 when the pressing ring 2 is not sleeved on the inner barrel 1. When the garbage bag needs to be sleeved, the reverse U-shaped part can be expanded. After the garbage bag is sleeved, the reverse U-shaped part restores the deformation, and the bag opening of the garbage bag can be clamped at the barrel opening of the inner barrel 1. The outer barrel 3 is telescopic and is sleeved outside the inner barrel 1 and is in sealed connection with the outer wall of the inner barrel 1 at the upper end, so that a second sealed cavity is formed between the inner barrel 1 and the outer barrel 3. First one-way exhaust structure 11 and second one-way exhaust structure 31 are arranged at the cavity walls of the inner barrel 1 and the outer barrel 3, respectively. The first one-way exhaust structure 11 only allows the gas in the first sealed cavity to flow to the second sealed cavity, but not to flow from the second sealed cavity to the first sealed cavity. The second one-way exhaust structure 31 only allows the gas in the second sealed cavity to flow to the external environment, but not to flow from the external environment to the second sealed cavity.
[0036] Therefore, when the outer barrel 3 performs a compression action, the volume of the second sealed cavity becomes smaller, the gas inside is compressed, so that the air pressure in the second sealed cavity is greater than that of the external environment, and at the same time is limited by the first one-way exhaust structure 11, the gas in the second sealed cavity flows to the external environment through the second one-way exhaust structure 31, just like orderly "exhale", and when the outer barrel 3 performs a stretching action, the volume of the second sealed cavity becomes larger, the gas pressure inside becomes smaller, so that the air pressure in the second sealed cavity is less than that in the first sealed cavity, and at the same time is limited by the second one-way exhaust structure 31, the gas in the first sealed cavity flows to the second sealed cavity through the first one-way exhaust structure 11, like "inhale" transfer, at this time the air pressure in the first sealed cavity is less than the external environment air pressure, so under the action of atmospheric pressure, the garbage bag is stretched in the inner cavity of the inner barrel 1, and when the outer barrel 3 is repeatedly stretched and contracted, the difference between the gas pressure in the first sealed cavity and the external environment gradually increases, so the user can determine the number of times of stretching and contracting the outer barrel 3 according to the degree of stretching of the garbage bag. The garbage can 3 of the application avoids the high production and manufacturing requirements of the existing technology of the piston principle garbage can exhaust structure and the cost burden caused by the damage in the use process by setting the outer barrel 3 as a telescopic structure. When manufacturing, the inner barrel 1 is made of solid and light plastic material and is integrally injection molded to ensure the regularity of the inner cavity, and the opening edge is polished smooth to facilitate the close fit of the compression ring 2. The compression ring 2 can be made of metal or hard plastic material and has a ring structure, which is locked with the opening of the inner barrel 1 through the clamping groove and buckle design, and firmly presses the garbage bag. The outer barrel 3 realizes telescopic by barrel body deformation, avoiding the complex structure of the existing technology. The setting of the first one-way exhaust structure 11 and the second one-way exhaust structure 31 makes the gas in the first sealed cavity and the second sealed cavity flow in one direction, follows the set flow direction to help the orderly transfer of air, completes the stretching action of the garbage bag, and the user only needs to stretch the outer barrel 3 as needed, and simple operation can keep the garbage bag in good use state.
[0037] In the present embodiment, the outer barrel 3 comprises a deformation section 32 shaped like a bellows, which is capable of excellent bending and stretching, and can change the overall height of the outer barrel 3 flexibly while maintaining a stable shape during repeated stretching and compression, without easily deforming and twisting to affect the integrity of the sealed cavity. In addition, the deformation section 32 can also be made of elastic materials to achieve the same effect, such as high-quality rubber, high-elastic plastic, etc. During production, high-strength rubber mixing process is adopted, and reinforcing fibers and additives are added in proportion to ensure that the material is wear-resistant and anti-aging. The first and second sealing cavities are tightly fitted on the outside of the inner barrel 1 after assembly, and are combined with sealing glue, sealing rings and other accessories to ensure the sealing of the first and second sealing cavities, so that each part of the garbage can can perform its function efficiently, and the outer barrel 3 is sufficiently elastic and flexible. When the user needs to frequently replace the garbage bag and arrange the space in the barrel during daily cleaning of the garbage can, the outer barrel 3 can be easily stretched or compressed.
[0038] Further, as shown in Figure 1 、 Figure 3 , the deformation section 32 of the outer barrel 3 is designed in a drum shape. Compared with the conventional cylindrical shape, the drum-shaped structure can increase the volume of the second sealing cavity. When the outer barrel 3 is activated to stretch and contract, the larger cavity volume means that more air can be accommodated, so that the air volume transferred and adjusted during each stretching and contraction increases, and the air pressure changes more efficiently. Unlike small-volume cavities, which require high-frequency reciprocating operation to achieve the desired air pressure difference, the garbage bag can be fully stretched and fitted in the first sealing cavity, thereby saving operation frequency and reducing labor consumption.
[0039] In some embodiments, because the wall of a general garbage can is relatively thin, the range of setting other structural components on the wall of the garbage can is limited. In addition, because the outer barrel 3 needs to move relative to the inner barrel 1 when it is compressed, in order to avoid affecting product use and reduce production and manufacturing difficulty, as shown in Figure 2 、 Figure 3 , the first one-way exhaust structure 11 is arranged at the bottom of the inner barrel 1. This arrangement also allows the garbage bag to fully expand to the bottom of the inner barrel 1, optimizing the capacity and efficiency.
[0040] In the present embodiment, a plurality of one-way valves are arranged along the circumference of the bottom of the inner barrel 1 as the first one-way exhaust structure 11. Because the plurality of one-way valves operate synchronously from the circumference, the gas can be transferred from the first sealing cavity to the second sealing cavity in multiple points, synchronously and orderly. With the exhaust of the gas, the bottom of the garbage bag is driven by the air pressure difference and can be smoothly expanded from the four sides of the bottom to the entire bottom area, effectively avoiding the problem of wrinkles and curling of the bottom of the garbage bag due to local exhaust obstruction, and allowing the garbage bag to fully expand on the bottom.
[0041] In this embodiment, as shown in Figure 2 、 Figure 3 , the first one-way exhaust structure 11 can also be composed of a plurality of first exhaust holes 111 uniformly distributed in the circumferential direction and a first plate-shaped plug body 112 with elastic deformation capability. When the garbage bag is not used or the air pressure in the garbage bag is stable, that is, the air pressure in the first sealing cavity is not greater than the air pressure in the second sealing cavity, the first plate-shaped plug body 112 tightly adheres to the lower side of the bottom of the inner barrel 1, and blocks the first exhaust hole 111. When the garbage bag needs to be set, that is, when the outer barrel body 3 is compressed, once the air pressure in the first sealing cavity is greater than the air pressure in the second sealing cavity, the gas pressure "drives" the first plate-shaped plug body 112 to elastically deform and lift away from the lower side of the bottom, unlocking the first exhaust hole 111, so that the gas is discharged into the second sealing cavity, thereby causing the garbage bag to be fully expanded from the bottom of the barrel. The first plate-shaped plug body 112 is generally made of high-elasticity and aging-resistant rubber material to ensure its long-lasting elasticity and sealing performance.
[0042] Further, as shown in Figure 2 , the first plate-shaped plug body 112 is designed to be concave downward and has a first annular table 1121 on the upper side. The concave downward design makes the first plate-shaped plug body 112 tightly adhere to the first exhaust hole 111 through the structural shape setting in addition to the deformation capability of the material itself, and the first annular table 1121 makes the first plate-shaped plug body 112 not be affected by its shape, thereby reducing the blocking effect on the first exhaust hole 111. As shown in Figure 3 、 Figure 5 , the first plate-shaped plug body 112 is generally directly connected to the bottom of the inner barrel 1 by screws or one-piece injection molding.
[0043] In this embodiment, as shown in Figure 2 、 Figure 6 , the second one-way exhaust structure 31 is arranged on the bottom of the outer barrel 3. When the outer barrel 3 is operated to reciprocally stretch and shrink, the gas in the second sealing cavity is squeezed to flow and is discharged to the external environment through the second one-way exhaust structure 31 on the bottom. In addition, the bottom end of the sidewall of the outer barrel 3 is lower than the bottom, and the bottom is provided with a ventilation groove 33, thereby forming an "exhaust passage" so that the gas discharged from the second sealing cavity can flow to the external environment, avoiding the situation that when the ground is too flat, the bottom of the outer barrel 3 is directly isolated from the external environment, thereby affecting the use effect of the product.
[0044] In this embodiment, the second one-way exhaust structure 31 can also be provided with a one-way valve or use Figure 6The second exhaust hole 311 in the second plate-shaped plug body 312 is combined in the same way as the first one-way exhaust structure 11, and the effect, material, and use are the same, and will not be repeated here. However, it should be noted that the exhaust capacity of the second one-way exhaust structure 31 should not be less than that of the first one-way exhaust structure 11, that is, it is necessary to ensure that the gas sucked into the second sealed cavity from the first sealed cavity during each extension and contraction of the outer barrel 3 can be completely exhausted to the external environment through this extension and contraction. To this end, when the second one-way exhaust structure 31 and the first one-way exhaust structure 11 both use one-way valves, if the specifications of the one-way valves are the same, the number of one-way valves of the second one-way exhaust structure 31 should not be less than that of the first one-way exhaust structure 11, and if the specifications of the one-way valves are different, the total flow area of the one-way valves of the second one-way exhaust structure 31 should not be less than that of the first one-way exhaust structure 11. Similarly, when the second one-way exhaust structure 31 and the first one-way exhaust structure 11 both use exhaust holes and plate-shaped plugs, the total cross-sectional area of the second exhaust hole 311 on the second one-way exhaust structure 31 should not be less than that of the first exhaust hole 111 on the first one-way exhaust structure 11.
