Description

Technical Field

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

[0002] As living standards improve, so too do people's expectations for household items, striving for a better quality of life. For example, household trash cans have evolved from a basic requirement for trash storage to requirements for odor prevention and automatic bagging. To meet these needs, automatic bagging cans have emerged. These use ropes or push rods to tie the garbage bag's opening, which is then sealed by a sealing mechanism, achieving automatic bagging.

[0003] Prior art, such as patent publication number CN220466437U, discloses a flexible packaging mechanism for a smart trash can. This mechanism uses a tightening rope to tighten the trash bags, which are then melted by a welding arm, achieving automatic packaging. However, because the tightening rope is a flexible component, the patent document also includes multiple coil springs connected to the tightening rope, which are used to drive the tightening rope to reset. However, using multiple coil springs to reset the tightening rope not only increases the cost of the trash can but also occupies the internal space of the trash can, reducing the usable volume of the trash can. Summary of the Invention

[0004] In response to the problems in the existing technology, the utility model proposes a track structure for a flexible belt bag collection. The flexible belt is guided by the track so that the flexible belt is automatically reset under the drive of the driving device. There is no need to set up an additional driving unit to drive the flexible belt to reset. While reducing the cost of the trash can, it also increases the available volume of the trash can and improves the space utilization of the trash can.

[0005] The present utility model is implemented as follows: a flexible bag collecting track structure is arranged at the delivery port of a trash can, comprising a bag collecting body, the middle part of which is connected to the delivery port; the bag opening of the garbage bag is arranged on the delivery port, and the bag body passes through the middle part of the bag collecting body; the bag collecting body is provided with an annular cavity around the delivery port, the inner side of the annular cavity is open and connected to the delivery port of the trash can; at least a support part is provided in the annular cavity, and a guide rail is provided on the support part from the inside to the outside; the inner side of the guide rail is open and connected to the delivery port of the trash can; a flexible belt adapted to the guide rail is also provided in the annular cavity, and the flexible belt is rolled up or unrolled along the extension direction of the guide rail to close or open the bag opening of the garbage bag. The guide rail is used to guide the flexible belt when it is reset. On the one hand, the flexible belt is stored in the annular cavity in an orderly manner when it is unwound, without affecting the movement of other mechanisms, reducing the friction resistance of each movable mechanism during movement, and improving the smoothness of each mechanism during movement; on the other hand, the flexible belt is reset without the need for an additional power source, which reduces the cost of the trash can and prevents the additional power source from occupying the volume of the trash can, thereby improving the space utilization rate of the trash can.

[0006] Preferably, the guide rail is formed by multiple straight segments and / or arc segments connected end to end in sequence, and the connection between each straight segment and / or arc segment is an arc transition, which can prevent the flexible belt from getting stuck at the connection between each straight segment and / or arc segment during the resetting process, thereby improving the smoothness of the flexible belt during resetting.

[0007] Preferably, the guide rail is inclined at both its starting and ending points, with the starting point gradually approaching the delivery port along its extension direction, and the ending point gradually moving away from the delivery port along its extension direction, so that both ends of the guide rail gradually move away from the delivery port, thereby increasing the area between the inner boundary of the support portion and the intersection of the guide rail during a circle. Since a trash bag is provided in the delivery port of the trash can, when both ends of the guide rail gradually move away from the delivery port, the flexible belt can be kept as far away from the delivery port as possible after being reset, preventing the flexible belt from being exposed inside the delivery port and affecting the user's replacement of the trash bag, thereby improving the reliability of the flexible belt. Furthermore, since the flexible belt may be partially suspended during the winding or unwinding process, the area between the inner boundary of the support portion and the intersection of the guide rail during a circle can be increased, thereby improving the support effect of the support portion on the flexible belt, preventing the suspended portion of the flexible belt from sagging, which may cause winding or unwinding jams, thereby improving the smoothness of the winding and unwinding of the flexible belt.

[0008] Specifically, the annular cavity includes a top plate and a bottom plate, respectively, located at the top and bottom. The circumferential sides of the top / bottom plates extend toward the bottom / top plates to form side plates, with the bottom plates serving as the support portion. The ends of the guide rails connect to the inner walls of the side plates, forming extensions of the guide rails. By using the inner walls of the side plates as extensions of the guide rails, the number of turns of the guide rails can be reduced while ensuring proper guidance. This simplifies the rail structure, reduces the raw materials used to produce the guide rails, and lowers the production cost of the trash can.

[0009] Specifically, an abutment portion is provided on the end or extended portion of the guide rail, and a driving unit that drives the flexible belt to reciprocate presses the flexible belt against the abutment portion. The side of the abutment portion that abuts the flexible belt is adapted to the driving unit. Since the flexible belt is flexibly deformed when abutted by the driving unit and the abutment portion, when the side of the abutment portion that abuts the flexible belt is adapted to the driving unit, the flexible belt can fully contact the driving unit, thereby improving the reliability of the reciprocating motion of the flexible belt.

[0010] Preferably, a first stopper is provided on the side of the top plate facing the guide rail, adapted to fit the starting and ending ends of the guide rail. A second stopper is provided on the side of the bottom plate facing the guide rail, adapted to fit the starting and ending ends of the guide rail. Portions of the flexible belt corresponding to the starting and ending ends of the guide rail are respectively sandwiched between the first and second stopper. The flexible belt is used to constrict the opening of the garbage bag to facilitate sealing of the garbage bag by the sealing device on the trash can. The first and second stopper are used to limit the flexible belt after constricting the garbage bag, preventing it from entering the operating range of the sealing device, thereby improving the reliability of the flexible belt.

[0011] Specifically, the connection between the first limiting portion and the top plate is inclined to form a first guide portion; the connection between the second limiting portion and the bottom plate is inclined to form a second guide portion; the first and second guide portions are arranged opposite each other to form a trumpet-shaped guide opening. The guide opening is used to guide the flexible belt that is gathering the garbage bag, allowing the flexible belt to be smoothly sandwiched between the first and second limiting portions, thereby improving the smoothness of the flexible belt when gathering the garbage bag.

[0012] Preferably, the guide rail and the base plate are integrally formed, so that the guide rail does not need to be fixed to the base plate by installation, which simplifies the installation steps of the track structure and improves the installation convenience of the track structure.

[0013] Preferably, the number of turns of the guide rail is 1. The number of turns of the flexible belt after contraction is 1. When the number of turns of the track is exactly 1, it is adapted to the number of turns of the flexible belt. Under the premise of ensuring that the guide rail has the best guiding function for the flexible belt, the length of the guide rail is shortened as much as possible to prevent the annular cavity from being overcrowded, which makes the installation of the flexible belt inconvenient.

[0014] As an equivalent alternative, the number of revolutions of the guide rail is greater than or less than 1.

[0015] Beneficial effects of the utility model:

[0016] The utility model proposes a track structure for a flexible belt bag collection, which guides the flexible belt through the track. On the one hand, the flexible belt is stored in an annular cavity in an orderly manner when unwinding, without affecting the movement of other mechanisms, reducing the friction resistance of each movable mechanism during movement, and improving the smoothness of each mechanism during movement; on the other hand, the flexible belt is automatically reset under the drive of the driving device, and there is no need to set up an additional driving unit to drive the flexible belt to reset. While reducing the cost of the trash can, it also increases the available volume of the trash can and improves the space utilization rate of the trash can. BRIEF DESCRIPTION OF THE DRAWINGS

[0023] 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.

[0024] like Figures 1-4 As shown, a flexible bag collecting track structure is provided at the opening of a trash can, comprising a bag collecting body, the middle portion of which is connected to the opening; the opening of the trash bag is sleeved over the opening, with the bag body passing through the middle portion of the bag collecting body; the bag collecting body is provided with an annular cavity 7 surrounding the opening, the inner side of the annular cavity 7 being open and connected to the opening of the trash can; at least a support portion is provided within the annular cavity 7, and a guide rail 5 is provided on the support portion in a spiral manner from the inside to the outside;

[0025] In this embodiment, the guide rail 5 is formed by multiple straight segments connected end to end in sequence, and the connection between the straight segments is an arc transition, which can prevent the flexible belt 4 from getting stuck at the connection between the straight segments during the reset process, thereby improving the smoothness of the flexible belt 4 during reset.

[0026] The guide rail 5 is open on its inner side and communicates with the trash can's delivery port. A flexible belt 4, adapted to the guide rail 5, is also disposed within the annular cavity 7. The flexible belt 4 winds or unwinds along the extension of the guide rail 5 to close or open the opening of the trash bag. The guide rail 5 guides the flexible belt 4 during repositioning, enabling it to be repositioned without requiring an additional power source. This reduces the cost of the trash can while preventing an additional power source from occupying the trash can's volume, thereby improving space utilization.

[0027] In this embodiment, the number of revolutions of the guide rail 5 is less than 1. While ensuring the guiding function of the guide rail 5 on the flexible belt 4, the length of the guide rail 5 is shortened to prevent the annular cavity 7 from being too crowded, which makes the installation of the flexible belt 4 inconvenient, thereby improving the installation convenience of the flexible belt 4.

[0028] In this embodiment, the starting end 51 and the end 52 of the guide rail 5 are both inclined, and the starting end 51 of the guide rail 5 gradually approaches the delivery port along the extension direction of the guide rail 5; the end 52 of the guide rail 5 gradually moves away from the delivery port along the extension direction of the guide rail 5, so that the two ends of the guide rail 5 gradually move away from the delivery port, so that the area between the guide rail 5 near the intersection point and the inner boundary of the support part increases in a circle. Since a garbage bag is provided in the delivery port of the garbage bin, when the two ends of the guide rail 5 gradually move away from the delivery port, the reset flexible belt 4 can be kept as far away from the delivery port as possible, preventing the flexible belt 4 from being exposed in the delivery port and affecting the user's replacement of the garbage bag, thereby improving the reliability of the flexible belt 4; at the same time, since the flexible belt 4 will be partially suspended in the process of winding or unwinding, the area between the guide rail 5 and the inner boundary of the support part near the intersection point increases during a circle, which can improve the supporting effect of the support part on the flexible belt 4, prevent the suspended part of the flexible belt 4 from sagging, causing winding or unwinding jamming, and improve the smoothness of the flexible belt 4 during winding and unwinding.

[0029] Specifically, the annular cavity 7 includes a top plate 2 and a bottom plate 1, respectively disposed at the upper and lower sides. The circumferential sides of the top plate 2 / bottom plate 1 extend toward the bottom plate 1 / top plate 2 to form side plates 3, with the bottom plate 1 serving as the support portion. The distal end 52 of the guide rail 5 is connected to the inner wall of the side plate 3, forming the inner wall of the side plate 3 as an extension of the guide rail 5. By using the inner wall of the side plate 3 as an extension of the guide rail 5, the number of turns of the guide rail 5 can be reduced while ensuring the guiding function of the guide rail 5. This simplifies the structure of the rail 5, reduces the raw materials used to produce the guide rail 5, and reduces the production cost of the trash can.

[0030] In this embodiment, the guide rail 5 is integrally formed with the base plate 1 , so that the guide rail 5 does not need to be fixed to the base plate 1 by installation, which simplifies the installation steps of the rail 5 structure and improves the installation convenience of the rail 5 structure.

[0031] Specifically, an abutment portion 53 is provided on the end 52 or the extended portion of the guide rail 5, and a driving unit that drives the flexible belt 4 to reciprocate presses the flexible belt 4 against the abutment portion 53. The side of the abutment portion 53 that abuts the flexible belt 4 is adapted to the driving unit. Since the flexible belt 4 is flexibly deformed when abutted by the driving unit and the abutment portion 53, when the side of the abutment portion 53 that abuts the flexible belt 4 is adapted to the driving unit, the flexible belt 4 can be fully in contact with the driving unit, thereby improving the reliability of the reciprocating motion of the flexible belt 4.

[0032] In this embodiment, the top plate 2 is provided with a first limiting portion 21 on the side facing the guide rail 5, which is adapted to the starting end 51 and the ending end 52 of the guide rail 5. The bottom plate 1 is provided with a second limiting portion 11 on the side facing the guide rail 5, which is adapted to the starting end 51 and the ending end 52 of the guide rail 5. The portions of the flexible belt 4 corresponding to the starting end 51 and the ending end 52 of the guide rail 5 are respectively sandwiched between the first limiting portion 21 and the second limiting portion 11. Since the flexible belt 4 is used to constrict the opening of the garbage bag to facilitate sealing of the garbage bag by the sealing device on the garbage bin, the first limiting portion 21 and the second limiting portion 11 are used to limit the flexible belt 4 after constricting the garbage bag, preventing the flexible belt 4 from entering the working range of the sealing device, thereby improving the reliability of the flexible belt 4.

[0033] Specifically, the first limiting portion 21 is inclined at its connection with the top plate 2 to form a first guide portion 22; the second limiting portion 11 is inclined at its connection with the bottom plate 1 to form a second guide portion 12; the first guide portion 22 and the second guide portion 12 are arranged opposite each other to form a trumpet-shaped guide opening 6. The guide opening 6 is used to guide the flexible belt 4 during the collection of the garbage bag, allowing the flexible belt 4 to be smoothly sandwiched between the first limiting portion 21 and the second limiting portion 11, thereby improving the smoothness of the flexible belt 4 when collecting the garbage bag.

[0034] 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.
