Description

Technical Field

[0001] The utility model belongs to the field of trash cans, and particularly relates to a bag-dropping prevention structure of a trash can. Background Art

[0002] Trash cans are simple containers used to collect and dispose of household waste. Made mostly of metal or plastic, they offer limited functionality and lack intelligence and convenience. With technological advancements, sensor-based trash cans are becoming increasingly popular. These use infrared, voice control, weight-sensing sensors to automatically open and close, improving convenience and hygiene. With accelerating urbanization, population growth, and rising consumption levels, the amount of waste is increasing, and traditional methods of waste disposal are no longer sufficient. At the same time, people's environmental awareness and aesthetic tastes are also rising, placing higher demands on the type, function, and appearance of trash cans. Therefore, intelligent, convenient, and environmentally friendly trash cans are becoming key market trends.

[0003] Trash cans are a common sight in everyday life, but existing designs have some drawbacks. For example, when a can is loaded with heavy or excessive amounts of trash, the trash bag can easily fall into the can, causing not only dirty hands when emptying the trash but also the can itself, making cleaning inconvenient. Furthermore, when putting a trash bag in place, the bag is often difficult to secure due to the discrepancy between the can's opening and the size of the bag, making it prone to slipping when dumping the trash.

[0004] Some existing trash cans feature a ring that fits over the opening of the trash can, securing the trash bag between them. However, this often creates a gap between the can body and the ring. When the bag contains a large amount of trash or the bag opening is too large, the bag can slip out of the ring, resulting in a loose, loose attachment and the bag falling out. Furthermore, when the ring is used to secure the trash can, friction and poor engagement can easily occur, causing the bag to become stuck and damaged. Other designs for securing the trash bag are relatively complex, costly, and prone to malfunction.

[0005] The Chinese patent with announcement number CN210126822U discloses an intelligent trash can that automatically compresses garbage bags. The intelligent trash can uses a power supply to provide power and controls a pushing device to tighten the garbage bags. The intelligent trash can requires power supply, has a complex design, and is relatively expensive. Summary of the Invention

[0006] In response to the problems in the related technology, the utility model proposes a bag-drop prevention structure for a trash can, in which a flexible pressure block is arranged between the barrel ring and the barrel body. The elastic force generated by the flexible pressure block is used to fix the trash bag between the barrel ring and the barrel body, preventing the trash bag from falling into the barrel body due to the gap between the barrel ring and the barrel body.

[0007] The utility model is achieved in this way:

[0008] A bag-drop prevention structure for a trash can comprises a flexible pressing block disposed between a trash can body and a trash can ring. The upper end of the trash can body is provided with an opening, and a trash bag is sleeved on the open end of the trash can body. The trash can ring can be sleeved on the outer side of the open end of the trash can body and is adapted to the outer size of the open end of the trash can body.

[0009] The flexible pressing block is fixed on the side of the barrel ring facing the open end of the barrel body; the flexible pressing block extends from the side where it is fixed toward the barrel body to form a pressing plate portion, and the end of the pressing plate portion is bent toward the outer periphery of the barrel body to form a bent portion;

[0010] The barrel ring cover is placed toward the outside of the open end of the barrel body, and the bending structure of the flexible pressing block is connected to the outside of the open end of the barrel body, pressed against the garbage bag, and continued to press downward along the outside of the open end of the barrel body until the bending structure of the flexible pressing block is separated from the outside of the open end of the barrel body. The barrel body and the pressure plate part are squeezed against each other to fix the garbage bag between the outside of the open end of the barrel body and the pressure plate part.

[0011] Preferably, the barrel ring and the open end of the barrel body are hinged or detachably connected to each other; at least two flexible pressure blocks are provided in the barrel ring, and the positions of the flexible pressure blocks correspond to each other.

[0012] Specifically, the positions of the multiple flexible pressing blocks correspond to each other, which can ensure balance when the garbage bag is fixed by the flexible pressing blocks, and avoid damage to the unfixed part of the garbage bag due to imbalance.

[0013] Preferably, the flexible pressing blocks are arranged on both sides of the hinge between the barrel ring and the barrel body.

[0014] Specifically, the barrel ring and the barrel body are hinged to each other. When the barrel ring is covered to the barrel body through the hinge, the bending structure of the flexible pressing block is fully in contact with the outer side of the opening end of the barrel body, thereby making the garbage bag more firmly fixed.

[0015] Preferably, the flexible pressure block includes a fixing portion, a pressure plate portion and a bending portion; a ring groove is provided on the side where the barrel ring is connected to the open end of the barrel body, a fixing groove is provided in the ring groove, and the fixing portion is matched with the fixing groove; a pressure plate portion is provided extending from the fixing portion to the side away from the fixing groove, and the end of the pressure plate portion is a bending portion.

[0016] Specifically, the fixing portion is provided with a screw hole and is fixed in the fixing groove through the screw hole; the bending portion is intended to enable the barrel ring to be in frontal contact with the outer side of the opening end of the barrel body when it is sleeved on the opening end of the barrel body, so that the bending portion can fully abut against the outer side of the opening end of the barrel body, thereby facilitating the smooth contact between the pressure plate portion and the outer side of the opening end of the barrel body during the subsequent downward pressing process.

[0017] Preferably, the pressing plate portion is located at one end close to the inner side of the annular groove; the fixing portion is located at one end close to the outer side of the annular groove; and the bending portion is bent from the pressing plate portion toward the outer side of the annular groove.

[0018] Specifically, the pressure plate portion is close to the inner side so that it can be squeezed against the outer side of the opening end of the barrel body; the fixing portion is close to the outer side to ensure that the pressure plate portion can appropriately produce flexible deformation when squeezed, thereby generating pressure on the outer side of the opening end of the barrel body; and the contact starts through the bending portion, which can guide the pressure plate portion to press smoothly.

[0019] Preferably, a reinforcing rib is provided at the position where the fixing portion and the pressure plate portion meet, the reinforcing rib is located at one end close to the inner side of the annular groove, and the reinforcing rib is inclined toward the side where the barrel body is located.

[0020] Specifically, the reinforcing ribs are used to prevent the pressure plate from being deformed when it is squeezed against the open end of the barrel body, which may cause the pressure plate to break or be unable to recover after deformation. They protect the pressure plate and improve its flexibility.

[0021] Preferably, the fixing portion and the pressing plate portion, and the pressing plate portion and the bending portion are both arc-shaped structures.

[0022] Specifically, the arc structure between the fixing portion, the pressing plate portion and the bending portion can improve the smoothness of the flexible pressing block when it is connected with and pressed against the open end of the barrel body and fixes the garbage bag, thereby preventing it from getting stuck.

[0023] Preferably, the end of the bending portion is bent toward the outside of the barrel body to form a folded section, and an arc-shaped depression is provided in the middle of the folded section.

[0024] Specifically, the folded section can play a protective role, preventing the bent portion from being hooked on the garbage bag during the abutment process, thereby preventing the garbage bag from being damaged.

[0025] Preferably, a pressing portion is provided on the outer side of the open end of the barrel body, and the position of the pressing portion corresponds to the position of the flexible pressing block.

[0026] Specifically, a pressing portion is provided at the open end of the barrel body, which can better adapt and squeeze with the flexible pressing block to fasten the garbage bag between the two.

[0027] Preferably, the flexible pressing block is integrally formed.

[0028] Specifically, the one-piece molding design of the flexible pressing block mainly utilizes the flexibility of the flexible pressing block to apply elastic force to the open end of the barrel body, thereby fixing the garbage bag and preventing the garbage bag from falling out from between the barrel ring and the barrel body.

[0029] Compared with the prior art, the present invention achieves the following beneficial effects:
