Description

Technical Field

[0001] The utility model belongs to the field of trash cans, and in particular relates to a limit block structure with a flexible bag collection belt. Background Art

[0002] As people's living standards improve, their pursuit of quality of life also increases, and some traditional household items can no longer meet people's needs. For example, in the field of garbage disposal, traditional trash cans have problems such as poor sealing that leads to odor and unsanitary garbage packaging, which makes it difficult to meet people's higher demands for odor prevention and hygiene. In order to meet people's increasing needs, automatic packaging trash cans have appeared on the market, but existing automatic packaging trash cans usually use a heat-sealing rod that moves laterally to close the mouth of the garbage bag. The heat-sealing rod needs to achieve high movement accuracy and needs to be guided during movement to prevent the heat-sealing rod from tilting during movement, which in turn causes the garbage bag to not be completely sealed. However, setting a guide mechanism in the trash can will make the structure of the trash can more complicated, the control more cumbersome and the cost higher.

[0003] In the prior art, for example, patent document CN215754406U discloses an intelligent trash can that seals a trash bag by driving a heat-sealing strip to move laterally via a screw rod. However, the heat-sealing strip is at risk of tilting during its laterally moving movement for guidance, which means that the trash bag may not be completely sealed. Even if a guiding mechanism is added to the trash can, the structure of the trash can will be more complicated and the cost will be higher. Summary of the Invention

[0004] In response to the problems in the existing technology, the utility model proposes a limit block structure for a flexible belt bag collection, so that the flexible belt drives the limit block to slide when collecting the garbage bag. The sliding of the limit block prevents the garbage bag from leaking during the bag collection process, thereby improving the sealing effect of the garbage bag.

[0005] The present invention is implemented as follows: a flexible belt bag-collecting limit block structure is installed on a flexible bag-collecting mechanism of a trash can. The flexible bag-collecting mechanism is located at the trash can's delivery port and includes a flexible belt arranged around the delivery port, a drive unit for driving the flexible belt to tighten or expand, and a bag-collecting body to which the flexible belt and the drive unit are mounted. When a trash bag is placed in the trash can, the flexible belt is sleeved around the outer circumference of the trash bag. When the trash bag is sealed, the drive unit tightens the flexible belt to close the opening of the trash bag, facilitating heat sealing.

[0006] The limit block structure includes a limit block, which is movably connected to the bag receiving body. At least one bag opening folding point is provided on the periphery of the delivery port. The garbage bag is placed at the delivery port, and the flexible belt folds the garbage bag to the bag opening folding point.

[0007] The limiting block is provided with a sliding groove for the flexible belt to pass through. One end of the flexible belt is connected to the driving unit, and the other end passes through the sliding groove and extends around the delivery port to the bag opening closing point. When the flexible belt is tightened, the limiting block approaches the bag opening closing point; when the flexible belt is expanded, the limiting block moves away from the bag opening closing point. The flexible belt is connected to the limiting block via the sliding groove, and can drive the limiting block to slide as the flexible belt is tightened, so that the flexible belt and the limiting block move synchronously, thereby allowing the limiting block to assist the flexible belt in closing the garbage bag opening, preventing the garbage bag from leaking during sealing, and improving the reliability of the garbage bag sealing.

[0008] Preferably, a guide rail for the sliding of the limit block is provided on the bag receiving body, and a protrusion is provided at the bottom of the limit block which is slidably connected to the guide rail. The width of the guide rail is greater than the diameter of the protrusion, so that a gap is formed between the protrusion and the guide rail, ensuring that the limit block moves smoothly in the guide rail, thereby improving the movement smoothness of the limit block.

[0009] Preferably, the device further includes an elastic unit, one end of which is fixedly connected to the bag receiving body and the other end of which is elastically connected to the protrusion; the elastic unit extends in the same direction as the guide rail. The elastic unit is used to drive the limit block to reset after the garbage bag is sealed, thereby improving the convenience of the limit block. At the same time, during the automatic reset process, the limit block restricts the shape of the flexible belt during the relaxation process, ensuring that the flexible belt is not exposed at the delivery port, further improving the practicality of the limit block.

[0010] Specifically, the elastic unit is a tension spring. Compared with a compression spring, a tension spring has higher reliability. When a compression spring undergoes elastic deformation, there is a situation where the direction of the force driving the compression spring to compress is different from the extension direction of the compression spring, which may cause the compression spring to bend and deform, and there is a risk of the compression spring falling off.

[0011] Specifically, a sliding portion is formed at the sliding connection between the limit block and the guide rail, and the sliding portion is connected to the surface of the guide rail in a sliding or sliding rotation manner. Since one end of the elastic unit is elastically connected to the protrusion, when the elastic unit pulls the limit block to reset, it will generate a turning torque on the limit block. When the sliding portion abuts against the surface of the guide rail in a sliding manner, it can reduce or eliminate the turning torque generated by the elastic unit on the limit block, preventing the limit block from turning under the action of the elastic unit, thereby improving the reliability of the limit block.

[0012] Specifically, the limit block is slidably connected to the guide rail in a sliding and rotating manner. A latch is provided on the end of the limit block away from the bag opening closing point. As the limit block slides toward the bag opening closing point, the latch rotates toward the bag opening closing point. When the limit block moves toward the bag opening closing point and simultaneously rotates toward the bag opening closing point, it can fold the garbage bag toward the bag opening closing point, assisting in closing the garbage bag opening, further improving the sealing effect of the garbage bag and reducing the risk of bag leakage during sealing. At the same time, when the limit block is connected to the guide rail in a sliding and rotating manner, the force angle of the limit block driven by the flexible belt can be improved, making the movement of the limit block smoother.

[0013] Specifically, a fuse is provided at the bag opening's closing point, adjacent to the drive unit. When the stopper reaches the bag opening's closing point, the latch connects with the fuse. When connected, the latch ensures that the garbage bag, after being tightened by the flexible band, is completely within the fuse's melting range, further improving the garbage bag's sealing performance and reducing the risk of bag leakage during sealing.

[0014] Specifically, the fuse is provided with a snap-fitting portion adapted to the snap-fitting portion. When the limit block abuts the limit portion at one end of the guide rail proximate the drive unit, the snap-fitting portion snaps into engagement with the snap-fitting portion. The snap-fitting portion and the fuse are snapped into engagement, allowing the limit block and the fuse to partially overlap, further ensuring that the garbage bag, after being tightened by the flexible band, is completely placed within the fuse's melting range, further improving the garbage bag's sealing effectiveness and reducing the risk of bag leakage during sealing.

[0015] Preferably, the flexible belt is inserted into the sliding groove from top to bottom or bottom to top, and the width of the sliding groove is greater than the thickness of the flexible belt, so that a clearance fit is formed between the flexible belt and the sliding groove. When the flexible belt and the sliding groove are clearance-fitted, the movement speed of the flexible belt when tightened is greater than the movement speed of the limit block. Since the flexible belt and the limit block move synchronously, the movement stroke of the limit block is shortened while ensuring its function, the volume of the limit block structure is reduced, and the installation space of the limit block structure is saved.

[0016] Specifically, both ends of the sliding groove are provided with inclined and / or arc-shaped transition portions. Since there is a speed difference between the flexible belt and the stop block during movement, there is relative movement between the flexible belt and the stop block. The transition portions are used to provide an inclined or arc-shaped transition when the flexible belt passes through the sliding groove, reducing wear between the two components during relative movement and extending the service life of the flexible belt and the stop block.

[0017] Preferably, both ends of the guide rail protrude upward to form stoppers that mate with the stop block, and the stop block abuts against the stoppers when at its sliding limit position. The stoppers are used to limit the limit position of the stop block during movement, preventing the stop block from exceeding a set travel range during movement, thereby causing the stop block to affect the operation of other mechanisms, thereby improving the reliability of the stop block.

[0018] Beneficial effects of the utility model:

[0019] The utility model proposes a limit block structure for a flexible belt bag collection. The flexible belt is connected to the limit block through a sliding groove, and can drive the limit block to slide when the flexible belt is tightened, so that the flexible belt and the limit block move synchronously, and then the limit block assists the flexible belt to close the garbage bag, preventing the garbage bag from leaking when sealing, and improving the reliability of the garbage bag sealing; at the same time, when the limit block is connected to the guide rail in a sliding and rotating manner, it can improve the force angle of the limit block driven by the flexible belt, so that the movement of the limit block is smoother.

[0029] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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.

[0030] like Figures 1-6 The figure shows a flexible belt bag collection stopper structure, which is installed on the flexible bag collection mechanism of a trash can. The flexible bag collection mechanism is located at the trash can's delivery port and includes a flexible belt 1 arranged around the delivery port, a drive unit 2 that drives the flexible belt 1 to tighten or expand, and a bag collection body 3 to which the flexible belt 1 and drive unit 2 are mounted. When a trash bag is placed in the trash can, the flexible belt 1 is placed around the outer periphery of the trash bag. When the trash bag is sealed, the drive unit 2 tightens the flexible belt 1, closing the opening of the trash bag and facilitating heat sealing.

[0031] The limit block structure includes a limit block 4, which is movably connected to the bag receiving body 3. At least one bag opening folding point is provided on the periphery of the delivery port. The garbage bag is placed at the delivery port, and the flexible belt folds the garbage bag to the bag opening folding point.

[0032] The limit block 4 is provided with a sliding groove 41 for the flexible belt 1 to pass through. One end of the flexible belt 1 is connected to the driving unit 2, and the other end passes through the sliding groove 41 and extends around the delivery port to the bag opening closing point. When the flexible belt 1 is tightened, the limit block 4 approaches the bag opening closing point. When the flexible belt 1 is unfolded, the limit block 4 moves away from the bag opening closing point. The flexible belt 1 is connected to the limit block 4 through the sliding groove 41, and can drive the limit block 4 to slide while the flexible belt 1 is tightened, so that the flexible belt 1 and the limit block 4 move synchronously, and then the limit block 4 assists the flexible belt 1 in closing the garbage bag, preventing the garbage bag from leaking during sealing, thereby improving the reliability of the garbage bag sealing.

[0033] In this embodiment, the flexible belt 1 is inserted into the sliding groove 41 from top to bottom or from bottom to top, and the width of the sliding groove 41 is greater than the thickness of the flexible belt 1, so that a clearance fit is formed between the flexible belt 1 and the sliding groove 41. When the flexible belt 1 is clearance-fitted with the sliding groove 41, the movement speed of the flexible belt 1 when tightened is greater than the movement speed of the limit block 4. Since the flexible belt 1 and the limit block 4 move synchronously, the movement stroke of the limit block 4 is shortened while ensuring its function, the volume of the limit block structure is reduced, and the installation space of the limit block structure is saved.

[0034] Specifically, transition portions 43 with inclined or arc-shaped configurations are provided at both ends of the sliding groove 41. Since there is a speed difference between the flexible belt 1 and the stop block 4 during movement, there is relative motion between the flexible belt 1 and the stop block 4. The transition portions 43 are used to provide an inclined or arc-shaped transition when the flexible belt 1 passes through the sliding groove 41, reducing wear between the two components during relative motion and extending the service life of the flexible belt 1 and the stop block 4.

[0035] The bag receiving body 3 is provided with a guide rail 5 for the limiting block 4 to slide.

[0036] In this embodiment, both ends of the guide rail 5 protrude upward to form stoppers 51 that mate with the stopper 4. When the stopper 4 reaches its sliding limit position, it abuts against the stoppers 51. The stoppers 51 are used to limit the limit position of the stopper 4 during movement, preventing the stopper 4 from exceeding a set travel range and thereby affecting the operation of other mechanisms, thereby improving the reliability of the stopper 4.

[0037] Specifically, the limit block 4 is slidably connected to the guide rail 5 in a sliding and rotating manner. A latch 44 is provided at one end of the limit block 4 away from the bag opening closing point. The latch 44 rotates toward the bag opening closing point while sliding toward the bag opening closing point. When the latch 44 moves toward the bag opening closing point and simultaneously rotates toward the bag opening closing point, it can fold the garbage bag toward the bag opening closing point, assisting in closing the opening of the garbage bag, further improving the sealing effect of the garbage bag and reducing the risk of leakage during the sealing of the garbage bag. At the same time, when the limit block 4 is connected to the guide rail 5 in a sliding and rotating manner, it can improve the force angle of the flexible belt 1 driving the limit block 4, making the movement of the limit block 4 smoother.

[0038] Specifically, a fuse 6 is provided at the bag opening closing point, and the fuse 6 is disposed adjacent to the drive unit 2. When the stopper 4 reaches the bag opening closing point, the latch 44 connects with the fuse 6. When the latch 44 connects with the fuse 6, it ensures that the garbage bag is completely placed within the melting range of the fuse 6 after being tightened by the flexible belt 1, further improving the sealing effect of the garbage bag and reducing the risk of leakage during the sealing of the garbage bag.

[0039] Specifically, the limit block 4 is provided with a snap-on notch 44, and the fuse 6 is provided with a snap-on portion 61 that matches the snap-on notch 44. When the limit block 4 abuts the limit portion 51 of the guide rail 5 at one end near the drive unit 2, the snap-on notch 44 snaps into engagement with the snap-on portion 61. The snap-on engagement between the limit block 4 and the fuse 6 allows them to partially overlap, further ensuring that the garbage bag is completely placed within the melting range of the fuse 6 after being tightened by the flexible belt 1. This further improves the sealing effect of the garbage bag and reduces the risk of leakage during sealing.

[0040] The bottom of the stopper 4 is provided with a protrusion 42 that is slidably connected to the guide rail 5. The width of the guide rail 5 is greater than the diameter of the protrusion 42. The flexible belt 1 is connected to the stopper 4 via the sliding groove 41. When the flexible belt 1 is tightened, the stopper 4 is driven to slide, so that the flexible belt 1 and the stopper 4 move synchronously. In turn, the stopper 4 assists the flexible belt 1 in closing the garbage bag, preventing leakage during sealing and improving the reliability of the garbage bag sealing.

[0041] This embodiment further includes an elastic unit 7, one end of which is fixedly connected to the bag receiving body 3 and the other end of which is elastically connected to the protrusion 42. The elastic unit 7 extends in the same direction as the guide rail 5. The elastic unit 7 is used to reset the stopper 4 after the garbage bag is sealed, improving the convenience of the stopper 4. Furthermore, during the automatic reset process, the stopper 4 restricts the shape of the flexible band 1 during the relaxation process, ensuring that the flexible band 1 does not protrude from the delivery port, further enhancing the practicality of the stopper 4.

[0042] Specifically, a sliding portion 45 is formed at the sliding connection between the limit block 4 and the guide rail 5, and the sliding portion 45 slides against the surface of the guide rail 5. Since one end of the elastic unit 7 is elastically connected to the protrusion 42, when the elastic unit 7 pulls the limit block 4 to reset, it generates a turning torque on the limit block 4. When the sliding portion 45 slides against the surface of the guide rail 5, it can reduce or eliminate the turning torque generated by the elastic unit 7 on the limit block 4, preventing the limit block 4 from turning under the action of the elastic unit 7, thereby improving the reliability of the limit block 4.

[0043] Specifically, the elastic unit 7 is a tension spring. Compared with a compression spring, a tension spring has higher reliability. When a compression spring undergoes elastic deformation, there is a situation where the direction of the force driving the compression spring to compress is different from the extension direction of the compression spring, which will cause the compression spring to bend and deform, and there is a risk of the compression spring falling off.

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.
