Description

Technical Field

[0001] The utility model belongs to the field of trash cans, and in particular relates to a trash can drawstring opening structure that does not get stuck in the bag. Background Art

[0002] After filling a traditional trash can with trash, the bag typically needs to be manually removed and tied. This process is not only tedious and easily soiled, making it less convenient to use. During the packing process, bags can break or spill, potentially causing the trash to scatter, increasing cleaning difficulties and sanitation risks, resulting in poor overall hygiene. Some traditional trash cans have bags that easily slip or shift when inserted, and their securement is not secure enough, impacting usability and user experience. This has led to the development of trash cans with drawstrings. Drawstring bags feature a drawstring opening that allows for quick tightening, making handling and disposal more convenient and hygienic. However, existing trash can designs are not always fully compatible with drawstring bags. Sometimes, the rim of the can can get stuck on the bag opening, causing inconvenience. In some cases, the bag can become stuck in the drawstring channel when tightening the drawstring to collect the bag. Furthermore, the narrow channel makes inserting the drawstring difficult, making it difficult to replace the bag.

[0003] Chinese patent publication number CN219729260U discloses a trash can that facilitates the securement and drawstringing of trash bags. A clamp secures the drawstring, preventing the bag from slipping, but it does not address the problem of bag jamming. Another prior art design involves installing an elastic clamp at the drawstring opening to prevent the bag from getting stuck. However, this elastic clamp is complex and expensive. Summary of the Invention

[0004] In response to the problems in the related art, the utility model proposes a trash can drawstring opening structure that does not get stuck. A groove and a block are provided. The block structure and the groove are used to form a drawstring channel with a narrow entrance section, which prevents the trash bag from getting stuck in the drawstring channel when drawing the rope. At the same time, it is convenient to place and remove the drawstring, thereby preventing the bag from getting stuck and achieving the effect of smooth bag collection.

[0005] The utility model is achieved in this way:

[0006] A bag-free drawstring opening structure for a trash can comprises a barrel body with an opening on one side, a groove at the open end of the barrel body, and a stopper adapted to the groove;

[0007] The stopper includes a fixing portion and a baffle portion, and both sides of the fixing portion respectively form a spacing groove with the side surface of the groove on the side where the fixing portion is located;

[0008] The baffle portion is located on a surface close to the inner side of the barrel body, and extends toward the spacing grooves on both sides and covers or partially covers the spacing grooves, and the baffle portion does not connect with the barrel body; an entrance section is formed between the baffle portion and the barrel body, and the entrance section is connected to the spacing groove to form a rope drawing channel, and the width of the entrance section is smaller than the width of the spacing groove;

[0009] A garbage bag with a drawstring is provided in the barrel body. The drawstrings are tightened toward the outside of the barrel body through the drawstring channels on both sides of the block, and the garbage bag is blocked to the inside of the barrel body by the entrance section.

[0010] Preferably, the lower end of the fixing portion is tightly engaged in the groove, and both sides of the upper end of the fixing portion form spacing grooves with the side surfaces of the groove on the side where the fixing portion is located.

[0011] Specifically, the spacing grooves serve as a wider section of the drawstring channel, so that the drawstring can pass smoothly and pass through the spacing grooves on both sides, be put on the block, and circle around the inner side of the barrel.

[0012] Preferably, the groove is U-shaped, a fixing piece is provided in the groove, and a connecting piece adapted to the fixing piece is provided on the side where the stopper is connected to the groove. The stopper is installed on the fixing piece through the connecting piece and is connected to the groove.

[0013] Specifically, the stopper is arranged in the groove, and can be manually disassembled through the structure of the fixing part and the connecting part. The fixing part can also play a role in facilitating grasping during disassembly.

[0014] Preferably, the height of the baffle portion is greater than the height of the fixing portion, and the lower end of the fixing portion, on the side connected to the groove, is provided with a U-shaped support adapted to the shape of the groove, and the U-shaped support is tightly connected to both sides of the groove.

[0015] Specifically, the baffle portion is mainly used to block the drawstring channel and form a narrower entrance section with the barrel body, while preventing the entire drawstring channel from being straight. By blocking, the drawstring channel is made into a broken line shape; thereby preventing the garbage bag from entering the drawstring channel together with the drawstring when drawing the rope, thereby preventing the garbage bag from getting stuck, thereby achieving the effect of smooth drawing the rope and collecting the bag.

[0016] Preferably, a raised portion is provided on the inner side of the barrel body near the groove, and an inlet section is formed between the baffle portion and the raised portion on the side where the baffle portion is located.

[0017] Specifically, the protrusion can make the rope-taking channel between it and the baffle as narrow as possible, thereby preventing the garbage bag from passing through the rope-taking channel and getting stuck in the rope-drawing channel. At the same time, it is convenient to form a non-linear rope-drawing channel to prevent the bag from getting stuck.

[0018] Preferably, the upper ends of the baffle portion and the raised portion on the side close to each other are both arc-shaped structures.

[0019] Specifically, by providing an arc-shaped structure, it is convenient to put the drawstring into the drawstring channel or take it out from the drawstring channel.

[0020] Preferably, the baffle portion extends toward the spacing grooves on both sides, completely covering the spacing grooves, and continues to extend to overlap with the barrel body near the groove portion and is not connected to the barrel body.

[0021] Specifically, the baffle portion can extend to block or partially block the spacing groove, so that the drawstring channel is non-linear, preventing the garbage bag from being directly stuck in the drawstring channel; the baffle portion extends beyond the spacing groove and overlaps with the barrel body near the groove portion, forming an L-shaped drawstring channel, increasing the tortuosity of the drawstring channel, and further preventing the garbage bag from being stuck in the drawstring channel.

[0022] Preferably, the baffle portion and the fixing portion are integrally formed.

[0023] Specifically, the stopper is an integrally formed structure and can be directly disassembled. The overall structure is simple and the use is more convenient.

[0024] Preferably, the open end of the barrel body is a rectangular structure, and the groove and the stopper are symmetrically arranged on the longer side of the rectangular open end of the barrel body; a pressure plate is provided on the shorter side.

[0025] Specifically, the drawstring is sleeved on the block from the outside, enters the inner side of the barrel from the drawstring channels on both sides, and surrounds the barrel; the drawstring is pressed between the barrel and the pressure plate for fixation, so that the garbage bag can be completely unfolded in the barrel, avoiding a messy position of the drawstring.

[0026] Preferably, both ends of the pressure plate are fixed on the longer sides of the adjacent open ends and are provided with fixed points. The pressure plate abuts against the inner side of the barrel body and rotates within a limited angle around a fixed axis formed by the fixed points at both ends.

[0027] Specifically, the pressure plate is a rotatable structure, which can be lifted from the plane where the opening end of the barrel body is located, thereby releasing the fixation of the drawstring, pulling the drawstring out of the drawstring channel and tightening the bag opening, and then taking out the drawstring from the rope-taking channel to achieve bag collection.

[0028] Compared with the prior art, the present invention achieves the following beneficial effects:

[0029] The utility model provides a drawstring opening structure for a trash can that does not get stuck. The structure is provided with a groove and a stopper. A drawstring channel is formed between the stopper and the groove. The stopper structure blocks the gap with the groove, i.e., the spacing groove, so that the drawstring channel becomes non-linear, thereby preventing the trash bag from entering the drawstring channel and getting stuck. The narrow entrance section of the drawstring channel can further effectively prevent the trash bag from entering the drawstring channel. Thus, the effect of not getting stuck when the drawstring is pulled out is achieved, and the trash bag can be collected smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0045] Example

[0046] like Figures 1 to 11 A non-stuck trash can drawstring opening structure includes a barrel body 101 with an opening on one side, a groove 102 is provided at the open end of the barrel body 101, and a stopper 201 adapted thereto is provided in the groove 102;

[0047] The stopper 201 includes a fixing portion 202 and a baffle portion 203. Both sides of the fixing portion 202 form a spacing groove 204 with the side surface of the groove 102 on the side where the fixing portion 202 is located.

[0048] The baffle portion 203 is located on a side close to the inner side of the barrel body 101. The baffle portion 203 extends toward the spacing grooves 204 on both sides and covers or partially covers the spacing grooves 204. The baffle portion 203 does not connect to the barrel body 101. An entrance section 103 is formed between the baffle portion 203 and the barrel body 101. The entrance section 103 is connected to the spacing grooves 204 to form a drawstring channel 104. The width of the entrance section 103 is smaller than the width of the spacing grooves 204.

[0049] A garbage bag with a drawstring is provided in the barrel body 101 . The drawstrings are tightened toward the outside of the barrel body 101 through the drawstring channels 104 on both sides of the block 201 . The garbage bag is blocked by the inlet section 103 and moved to the inside of the barrel body 101 .

[0050] In this embodiment, the baffle portion 203 completely covers the spacing groove 204;

[0051] The baffle portion 203 and the fixing portion 202 are integrally formed.

[0052] The stopper 201 is an integrally formed structure and can be directly disassembled. The overall structure is simple and the use is more convenient.

[0053] The lower end of the fixing portion 202 is tightly engaged in the groove 102 , and both sides of the upper end of the fixing portion 202 form spacing grooves 204 with the side surfaces of the groove 102 on the side where the fixing portion 202 is located.

[0054] The spacing grooves 204 serve as a wider section of the drawstring channel 104 , so that the drawstring can pass smoothly and pass through the spacing grooves 204 on both sides, be put on the block 201 , and circle around the inner side of the barrel body 101 .

[0055] The groove 102 is a U-shaped structure, and a fixing part 105 is provided in the groove 102. The side where the stopper 201 is connected to the groove 102 is provided with a connecting part 205 adapted to the fixing part 105. The stopper 201 is installed on the fixing part 105 through the connecting part 205 and is matched with the groove 102.

[0056] The stopper 201 is arranged in the groove 102 and can be manually disassembled through the structure of the fixing member 105 and the connecting member 205. The fixing part 202 can also play a role in being easy to grasp during disassembly.

[0057] The height of the baffle portion 203 is greater than the height of the fixing portion 202. The lower end of the fixing portion 202, on the side connected to the groove 102, is provided with a U-shaped support 206 adapted to the shape of the groove 102. The U-shaped support 206 is tightly connected to both sides of the groove 102.

[0058] The baffle portion 203 is mainly used to block the drawstring channel 104 and form a narrower entrance section 103 with the barrel body 101, while preventing the entire drawstring channel 104 from being straight. By blocking, the drawstring channel 104 is made into a broken line shape; thereby preventing the garbage bag from entering the drawstring channel 104 together with the drawstring when drawing the rope, thereby preventing the garbage bag from getting stuck, thereby achieving the effect of smooth drawstring and bag collection.

[0059] A protrusion 106 is provided on the inner side of the barrel body 101 near the groove 102 , and an inlet section 103 is formed between the baffle portion 203 and the protrusion 106 on its side.

[0060] The protrusion 106 can make the rope-drawing channel between it and the baffle portion 203 as narrow as possible, thereby preventing the garbage bag from passing through the rope-drawing channel and getting stuck in the rope-drawing channel 104. At the same time, it is convenient to form a non-linear rope-drawing channel 104 to prevent the bag from getting stuck.

[0061] The upper ends of the baffle portion 203 and the protruding portion 106 , which are close to each other, are both arc-shaped.

[0062] The arc-shaped structure makes it easier to put the drawstring into the drawstring channel 104 or take it out from the drawstring channel 104 .

[0063] The open end of the barrel body 101 is a rectangular structure. The groove 102 and the stopper 201 are symmetrically arranged on the longer side of the rectangular open end of the barrel body 101; a pressure plate 107 is provided on the shorter side.

[0064] The drawstring is sleeved on the block 201 from the outside, enters the inner side of the barrel body 101 from the drawstring channels 104 on both sides thereof, and wraps around the barrel body 101. The drawstring is pressed between the barrel body 101 and the pressure plate 107 for fixing, so that the garbage bag can be completely unfolded in the barrel, avoiding a messy position of the drawstring.

[0065] The two ends of the pressure plate 107 are fixed on the longer sides of the adjacent open end and are provided with fixing points 108. The pressure plate 107 abuts against the inner side of the barrel body 101 and rotates around a fixed axis formed by the fixing points 108 at its two ends within a limited angle.

[0066] The pressure plate 107 is a rotatable structure and can be lifted from the plane where the open end of the barrel body 101 is located, thereby releasing the fixation of the drawstring, pulling the drawstring out from the drawstring channel 104 and tightening the bag opening, and then taking out the drawstring from the drawstring channel to complete the bag collection.

[0067] This embodiment also provides another implementation method, in which the baffle portion 203 extends toward the spacing grooves 204 on both sides, completely covering the spacing grooves 204, and continues to extend, overlapping with the barrel body 101 near the groove 102, and not connected to the barrel body 101.

[0068] The baffle portion 203 can extend to block or partially block the spacing groove 204, thereby making the drawstring channel 104 non-linear, preventing the garbage bag from being directly stuck in the drawstring channel 104; the baffle portion 203 extends beyond the spacing groove 204 and overlaps with the barrel body 101 near the groove 102, forming an L-shaped drawstring channel 104, increasing the tortuosity of the drawstring channel 104, and further preventing the garbage bag from being stuck in the drawstring channel 104.

[0069] The present invention provides a drawstring opening structure for a trash can that prevents bags from getting stuck. The pressure plate 107 is lifted from the plane of the opening end of the trash can body 101 and rotated to release the drawstring from its position. The drawstring of the trash bag is then pulled tight along the drawstring channel 104 toward the outside of the trash can, gradually tightening the opening. Because the drawstring channel 104 is non-linear and the entrance section 103 is narrow, the trash bag is prevented from entering and getting stuck in the drawstring channel 104. After the bag opening is tightened, the drawstring is removed from the top. The drawstring of a new trash bag is then inserted into the drawstring channel 104 and secured with the pressure plate 107, completing the replacement of the trash bag.

[0070] Based on the disclosure and teachings of the above description, those skilled in the art may also make changes and modifications to the above embodiments. Therefore, the present invention is not limited to the specific embodiments disclosed and described above, and modifications and variations of the present invention should also fall within the scope of protection of the claims of the present invention. In addition, although certain specific terms are used in this description, these terms are for convenience only and do not constitute any limitation to the present invention.
