Description

Technical Field

[0001] This application relates to the technical field of household items, and particularly to a trash can. Background Art

[0002] A trash can is a container for holding garbage. When people use a trash can indoors, they usually put a garbage bag inside the trash can so that the trash can remains clean after long-term use.

[0003] There is a trash can with an inner and outer double barrel. After the garbage bag is sleeved on the inner barrel, the outer barrel is sleeved outside the inner barrel. When the outer barrel is pressed down, the movable structure inside the inner barrel can automatically attach the garbage bag to the inner wall of the inner barrel through negative pressure. After the outer barrel is removed, the movable part can rebound under the action of the elastic part. However, in actual use, the elastic force of the spring may be too large, causing the garbage in the garbage bag to spill out, or the spring may age, resulting in insufficient up and down travel of the movable part, so that the negative pressure generated is not enough to make the garbage bag fit the inner wall of the inner barrel, and the overall use effect is not good. Summary of the Utility Model

[0004] This application provides a trash can to at least solve the technical problem that the use effect of the trash can is poor due to the spring restriction of the movable part inside the inner barrel in the prior art.

[0005] To achieve the above object, this application provides a trash can, including a base, an inner barrel, and an outer barrel. The inner barrel is arranged on the base. The outer barrel is sleeved on the inner barrel in a shape-matching and vertically movable manner. An inner liner that is vertically movable and matches the inner barrel is arranged inside the inner barrel. A clamping structure for clamping and fixing is arranged between the inner barrel and the inner liner. The clamping structure can keep the inner liner away from the base. The outer barrel is in transmission connection with the inner liner. When the outer barrel moves downward, it can drive the inner liner to approach the base.

[0006] In some embodiments, a travel groove extending longitudinally is arranged on the side wall of the inner barrel, and a positioning portion that matches the travel groove and can be accommodated in the travel groove is convexly arranged on the outer side of the inner liner.

[0007] In some embodiments, the positioning portion is located at the lower end of the inner liner and extends outward to protrude from the travel groove. The outer barrel can abut against the positioning portion and drive the inner liner to move downward.

The second clamping portion and the third clamping portion are clamped and matched to fix the inner container.

[0011] In some of these embodiments, the second clamping portion and the third clamping portion form a one-way locking structure that facilitates clamping. The second clamping portion and the side wall of the inner cylinder form an elastic sheet structure that can move inward and outward, so that when the inner container moves downward, it is convenient for the third clamping portion to disengage from the second clamping portion.

[0012] In some of these embodiments, the lower end of the inner cylinder is circumferentially formed with an insertion end extending downward and a flange extending outward. The insertion end can be inserted into the inside of the base, and the flange can abut against the base.

[0013] In some of these embodiments, the inner side wall of the base is provided with an insertion portion, and an insertion groove is formed between the insertion portion and the inner side wall of the base. The insertion end at the lower end of the inner cylinder can be inserted into the insertion groove in the base.

[0014] In some of these embodiments, the inner side wall of the base is provided with a fourth clamping portion protruding relative to the inner side wall, and a clamping groove for cooperating with and clamping the fourth clamping portion is formed on the insertion end.

[0015] According to the above content, the beneficial effects of the present application are:

[0016] 1. Between the inner container and the inner cylinder, the inner container can be manually controlled to move away from the base and be clamped and fixed through the clamping structure, and there will be no situation where the inner container rebounds too violently or the spring ages, resulting in insufficient stroke and insufficient negative pressure.

[0029] This application provides a trash can, which includes a base, an inner cylinder and an outer cylinder. The inner cylinder is arranged on the base, and the outer cylinder is sleeved on the inner cylinder in a shape-matching and vertically movable manner. An inner liner that is vertically movable and matches it is arranged inside the inner cylinder. A clamping structure for cooperating and clamping and fixing is arranged between the inner cylinder and the inner liner. The clamping structure can keep the inner liner away from the base, and the outer cylinder is drivingly connected to the inner liner. When the outer cylinder moves downward, it can drive the inner liner to approach the base.

[0030] As shown in the embodiments Figures 1 to 6 A trash can includes a base 1, an inner cylinder 2 and an outer cylinder 3. The inner cylinder 2 is installed on the base 1, and the outer cylinder 3 is sleeved on the inner cylinder 2 in a shape-matching and vertically movable manner. An inner liner 4 that matches the inner shape of the inner cylinder 2 is arranged inside the inner cylinder 2, and the inner liner 4 can move vertically inside the inner cylinder 2. The outer cylinder 3 is drivingly connected to the inner liner 4. When the outer cylinder 3 moves downward, it can drive the inner liner 4 to move downward and approach the base.

[0031] Furthermore, a travel groove 2.1 extending longitudinally to the bottom is arranged on the side wall of the inner cylinder 2. A positioning portion 4.1 that protrudes from the outer side wall of the inner liner 4 and matches the number and size of the travel grooves 2.1 and can be accommodated in the travel groove 2.1 and move along the travel groove 2.1 is arranged. The positioning portion 4.1 is located at the lower end of the inner liner 4 and extends outward until it protrudes from the travel groove 2.1. The cooperation between the positioning portion 4.1 and the travel groove 2.1 can enable the inner liner 4 to move along the travel groove 2.1 inside the inner cylinder 2.

[0032] Further, a clamping structure for fitting and clamping fixation is provided between the inner cylinder 2 and the inner tank 4. The clamping structure can keep the inner tank 4 away from the base 1 without structures such as springs.

[0033] Specifically, the clamping structure includes a first clamping portion 5.1 provided at the upper end of the travel groove 2.1. The first clamping portion 5.1 is located on both the left and right sides of the travel groove 2.1 and protrudes toward the inner side of the travel groove 2.1. When the positioning portion 4.1 moves to the first clamping portion 5.1 in the travel groove 2.1 and continues to move upward, the positioning portion 4.1 will be clamped and fixed in the space formed by the first clamping portion 5.1 and the upper part of the travel groove 2.1, thereby fixing the inner tank 4.

[0034] Further, the clamping structure further includes a second clamping portion 5.2 provided on the inner side wall of the inner cylinder 2 and a third clamping portion 4.2 provided on the outer side wall of the inner tank 4. The second clamping portion 5.2 protrudes toward the inside of the inner cylinder 2, and the third clamping portion 4.2 protrudes toward the outside of the inner tank 4. The second clamping portion 5.2 and the third clamping portion 4.2 cooperate with each other to clamp and fix the inner tank 4.

[0035] Specifically, to ensure that the inner tank 4 is far enough away from the base 1, the height of the second clamping portion 5.2 is higher than the height of the travel groove 2.1, and the height of the third clamping portion 4.2 is higher than the height of the positioning portion 4.1. In this embodiment, the second clamping portion 5.2 is located at the upper end of the inner side wall of the inner cylinder 2, and the third clamping portion 4.2 is located at the upper end of the outer side wall of the inner tank 4.

[0036] Further, the second clamping portion 5.2 and the third clamping portion 4.2 form a one-way locking structure that facilitates mutual clamping, specifically a slope that facilitates mutual insertion and a contact surface that is not easily disengaged. The second clamping portion 5.2 and the side wall of the inner cylinder 2 form an elastically movable leaf spring structure. When the third clamping portion 4.2 moves to the second clamping portion 5.2 and continues to move upward, the third clamping portion 4.2 is clamped into the second clamping portion 5.2 through the slope of the one-way locking structure. At this time, the inner tank 4 is fixed relative to the inner cylinder 2. When the third clamping portion 4.2 is subjected to a downward force, it can push the second clamping portion 5.2 of the leaf spring structure to move toward the outside of the inner cylinder, and then disengage from the second clamping portion 5.2.

[0037] Further, the lower edge of the outer cylinder 3 can abut against the protruding positioning portion 4.1. When the outer cylinder 3 moves downward, it will drive the inner tank 4 to move downward together through the positioning portion 4.1.

[0038] Further, a plug-in end 2.2 extending downward and a flange 2.3 extending outward are formed along the circumference at the lower end of the inner cylinder 2. A plug-in portion 1.1 and a fourth clamping portion 1.3 protruding from the inner side wall are provided on the inner side wall of the base 1. A plug-in groove 1.2 is formed between the plug-in portion 1.1 and the inner side wall of the base 1. A clamping groove 2.4 for cooperating with the fourth clamping portion 1.3 for clamping and fixing is formed on the plug-in end 2.2. During installation, the plug-in end 2.2 at the lower end of the inner cylinder 2 is inserted into the plug-in groove 1.2 in the base 1, the fourth clamping portion 1.3 on the inner side wall of the base 1 is snapped into the clamping groove 2.4 on the plug-in end 2.2, and the flange 2.3 abuts against the upper end of the side wall of the base 1, so that the inner cylinder 2 can be stably installed on the base 1 and fixed relative to the base 1 in the circumferential direction.

[0039] Working principle: When in use, a garbage bag is sleeved inside the inner cylinder 2, and then the outer cylinder 3 is sleeved outside the inner cylinder 2 and moves downward. During the downward movement of the outer cylinder 3, the inner liner 4 is driven to move downward together through the positioning portion 4.1. The space inside the inner cylinder 2 where the garbage bag is accommodated changes. Based on the principle of pressure, the garbage bag is unfolded and adsorbed and attached to the side wall of the inner cylinder 2. When the garbage bag needs to be taken out, after removing the outer cylinder 3, the garbage bag can be taken out, and then the positioning portion 4.1 is manually toggled upward to toggle the positioning portion 4.1 in a direction away from the base 1 and snap it with the inner cylinder 2 for positioning, which is convenient for the next use.
