Description

Technical Field

[0001] This utility model relates to the field of garbage bin technology, and in particular to a garbage bag feeding mechanism and a garbage bin device. Background Technology

[0002] Currently, most trash cans are used by first putting on a trash bag; when the trash needs to be thrown away, the trash bag is removed, and then a new trash bag is put on, and so on. With the development of technology and the increasing convenience of life, people hope that trash cans can automatically put on trash bags and seal the trash bag when it is removed from the trash can to avoid getting their hands dirty from manual sealing. For example, the utility model patent for a trash can with application number CN2017113196386, entitled "Trash Can", describes a trash can where, when the trash bag is removed, the inner bin tilts, causing the upper end of the trash bag to come into contact with the lower plastic seal, the upper plastic seal, and the cutting head. The cutting head is located between the upper and lower plastic seals, which seal the trash bag intermittently, and the cutting head cuts the trash bag. When used again, the trash bag is carried out by the weight of the trash and fills the inner bin.

[0003] When in use, the garbage bag is installed in a contracted form at the top of the garbage can, forming a garbage bag loop. When filling the garbage can, the garbage enters from the top and comes into contact with the garbage bag. The garbage bag is pulled downwards by its own weight, and is gradually pulled out from the top of the garbage can. Because the garbage bag needs to enter from the top of the garbage can and relies on the weight of the garbage to enter the inner bin, the garbage bag is prone to getting stuck during this process. This causes the garbage bag to not sink into the inner bin in time, and the garbage will accumulate on the garbage bag until it overflows.

[0004] Therefore, a structure needs to be developed that ensures that the garbage bag is gradually moved out from the top of the garbage bin and into the garbage space. Summary of the Invention

Therefore, they should not be construed as limitations on this application.

[0030] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this application, "multiple" means two or more, unless otherwise explicitly specified.

[0031] The present invention will now be described in detail with reference to the accompanying drawings. Figures 1 to 6 As shown.

[0032] Example 1: See Figures 2 to 5 A garbage bag feeding mechanism includes: an upper housing 2, the upper end of which is provided with an annular groove 21 for accommodating garbage bag material; the middle part of the upper housing 2 is provided with a moving space 22 for the garbage bag material to move downward, and the side wall 24 of the moving space 22 is provided with at least one moving device 4 for driving the garbage bag material to move downward.

[0033] The trash can in this embodiment mainly consists of an upper shell 2 and a lower shell 1. The upper shell 2 is fixed to the lower shell 1. A receiving space for accommodating trash bags and trash is formed in the middle of the lower shell 1. This receiving space is connected to the moving space 22 of the upper shell 2. It can be understood that the trash can can also be used without the lower shell 1, directly suspending the trash bag in the air. In actual use, the trash bag material is fitted into the annular groove 21 in a ring shape. One end of the trash bag material extends into the moving space 22 and is sealed. The sealing can be done manually, such as by tying the end with a string, or by a sealing structure, such as by heat fusion sealing, where the end is heated and connected to the seal in a heat-fused state.

[0034] To facilitate the continuous downward movement of the garbage bag material along the moving space 22, this embodiment employs a moving device 4 installed on the side wall 24 of the moving space 22. The moving device 4 drives the garbage bag material to move continuously downwards, forming individual garbage bags. This moving device 4 can employ various structures, such as a combination of clamps or suction mechanisms and a lifting mechanism. The clamps or suction mechanism grips the side of the garbage bag material, and then, driven by the lifting mechanism, pulls the garbage bag material downwards. The clamps or suction mechanism then releases the garbage material. This process is repeated, continuously pulling the garbage bag material out of the annular groove 21 and into the moving space 22; then, with the assistance of a sealing mechanism, individual garbage bags are formed. In use, garbage is placed into the moving space 22 from above.

[0035] See Figure 1 , Figure 2 The side wall 24 of the moving space 22 is provided with two or more moving devices 4. When more than three are provided, preferably, the moving devices 4 are evenly distributed on the side wall 24.

[0036] To ensure the garbage bag material can be smoothly pulled into the moving space 22 by the moving device 4, two or more moving devices 4 are provided on the side wall 24 of the moving space 22. When two moving devices 4 are provided, they are positioned on both sides of the moving space 22, applying a pulling force to both sides of the garbage bag material. Alternatively, three or more moving devices 4 can be provided. In this case, it is understood that to ensure the garbage bag material moves evenly within the moving space 22, the moving devices 4 are preferably evenly distributed. In this embodiment, two moving devices 4 are provided on the side wall 24 of the moving space 22, positioned on both sides.

[0037] See Figure 3 , Figure 4 as well as Figure 5 The moving device 4 includes a main drive wheel 44 and a secondary drive wheel 45 for clamping garbage bag material; the main drive wheel 44 and the secondary drive wheel 45 are spaced apart, and a gap is formed between the main drive wheel 44 and the secondary drive wheel 45 for partial passage of garbage bag material; the moving device 4 also includes a drive mechanism, which drives the main drive wheel 44 and / or the secondary drive wheel 45 to rotate.

[0038] In this embodiment, the main drive wheel 44 and the auxiliary drive wheel 45 work together to convey the garbage bag material downwards when moving the garbage bag material. During operation, the drive mechanism drives the main drive wheel 44 to rotate, and a portion of the garbage bag material passes through the gap between the main drive wheel 44 and the auxiliary drive wheel 45. As it passes through, it is squeezed by the main drive wheel 44 and the auxiliary drive wheel 45. Therefore, when the main drive wheel 44 rotates, it also drives the auxiliary drive wheel 45 to rotate. The combined action of the main drive wheel 44 and the auxiliary drive wheel 45 will convey the garbage bag material downwards. It can be understood that the auxiliary drive wheel 45 can rotate passively, driven by the movement of the garbage bag material. Alternatively, it can rotate actively, connected to the drive mechanism and rotating under its influence. It can also be understood that the auxiliary drive wheel 45 can be connected to another drive mechanism, which drives the auxiliary drive wheel 45 to rotate in the opposite direction to the main drive wheel 44, i.e., one rotates clockwise and the other counterclockwise. Secondly, the secondary drive wheel 45 can also be driven by the same drive mechanism. It is connected to the drive mechanism through the transmission mechanism, and the secondary drive wheel 45 rotates synchronously with the main drive wheel 44 in opposite directions.

[0039] As one embodiment, it can be understood that the drive mechanism includes a drive motor 43, which is connected to the main drive wheel 44 through a transmission mechanism.

[0040] Setting the drive mechanism as a drive motor 43 is simple and practical. The drive motor 43 can be a servo motor, which can precisely control the amount of garbage bag material fed. In specific settings, due to the small thickness of the garbage bin, placing the servo motor along the axial direction of the main drive wheel 44 would be space-constrained and inconvenient. Therefore, this technical solution includes a transmission mechanism to connect the drive motor 43 to the main drive wheel 44. The transmission mechanism can be a helical gear set, belt drive mechanism, etc. The placement direction of the servo motor can be various, such as perpendicular to the axial direction of the main drive wheel 44, making the space design more flexible.

[0041] The specific structure can be as follows: the transmission mechanism includes a worm 48 connected to the drive motor 43 and a worm wheel 49 connected to the worm 48. A main shaft is connected to the middle of the main drive wheel 44. The main shaft is connected to the worm wheel 49 or a main intermediate transmission unit is connected between the main shaft and the worm wheel 49.

[0042] To facilitate the rotation of the main drive wheel 44, this technical solution selects a worm gear 49 and a worm 48 as the transmission mechanism. The worm 48 is connected to the shaft of the drive motor 43, and the worm gear 49 is coaxially connected to the main drive wheel 44. The worm gear 49 and worm 48 can achieve both speed reduction and change of transmission direction. Of course, the transmission mechanism can also be other mechanisms, such as multiple sets of helical gears. Secondly, for further speed adjustment, such as speed reduction, a main intermediate transmission unit can also be set between the main shaft and the worm gear 49.

[0043] See Figure 6 The main intermediate transmission unit includes a main intermediate gear 47 connected to the main rotating shaft, and a first transmission shaft connected to the middle of the worm gear 49. The first transmission shaft is connected to a first intermediate gear 410, and the main intermediate gear 47 meshes with the first intermediate gear 410.

[0044] For example, the main intermediate transmission unit adopts a gear transmission mechanism, which mainly uses a meshing main intermediate gear 47 and a first intermediate gear 410; if necessary, at least one other intermediate gear can also be set between the main intermediate gear 47 and the first intermediate gear 410; the speed ratio is further adjusted through the gear transmission mechanism to reduce the output speed of the motor. When the distance between the main shaft and the first transmission shaft is large, another structure can also be used: the main intermediate transmission unit includes a first synchronous pulley connected to the main shaft, and a first transmission shaft connected to the middle of the worm gear 49. The first transmission shaft is connected to a second synchronous pulley, and a synchronous belt is connected between the first synchronous pulley and the second synchronous pulley. It can be understood that the synchronous belt can be replaced by a belt, and the first synchronous pulley and the second synchronous pulley can be replaced by a first pulley and a second pulley. At this time, the main intermediate transmission unit adopts a synchronous belt transmission mechanism or a belt transmission mechanism, which has a relatively simple structure and smooth transmission.

[0045] See Figure 6 The secondary drive wheel 45 has a secondary shaft at its center, and a secondary intermediate transmission unit is connected between the secondary shaft and the worm gear 49. Preferably, the secondary intermediate transmission unit includes a secondary intermediate gear 412 connected to the secondary shaft, the secondary intermediate gear 412 meshing with the worm gear 49, or the secondary intermediate gear 412 meshing with a second intermediate gear 411, and the second intermediate gear 411 meshing with a first intermediate gear 410.

[0046] When the secondary drive wheel 45 also actively drives the garbage bag material feeding, the secondary drive wheel 45 can also be connected to the drive motor 43 or the worm gear 49 through the secondary intermediate transmission unit. While driving the main drive wheel 44 to rotate, the drive motor 43 or the worm gear 49 also drives the secondary drive wheel 45 to rotate. Therefore, a secondary shaft is provided in the middle of the secondary drive wheel 45, and the secondary shaft is connected to the secondary intermediate gear 412. The secondary intermediate gear 412 can directly mesh with the worm gear 49, or it can mesh with the first intermediate gear 410 through the second intermediate gear 411. Of course, an even number of intermediate gears can be additionally set between the second intermediate gear 411 and the first intermediate gear 410. The secondary intermediate transmission unit can also adopt a belt drive mechanism, etc.

[0047] See Figure 3 , Figure 4 The mobile device 4 includes a fixed plate 42, a drive motor 43 fixed to the fixed plate 42, and two covers 41 connected to one side of the fixed plate 42. The covers 41 are used to cover the main drive wheel 44 and the auxiliary drive wheel 45. A gap is left between the two covers 41 for garbage bag material to pass through. A rear cover 46 is connected to the other side of the fixed plate 42. A transmission mechanism is set between the rear cover 46 and the fixed plate 42. The rear end of the rear cover 46 is fixed to the upper housing 2 by a connector.

[0048] A fixing plate 42 is provided to facilitate the fixation of the moving device 4; a cover 41 is used to house the main drive wheel 44 and the auxiliary drive wheel 45 to prevent external interference. Furthermore, a gap is left between the two covers 41 to allow the garbage bag to pass through; during operation, the garbage bag passes through the gap. The fixing plate 42, connected to the rear cover 46, houses the transmission mechanism, which also prevents external interference to the transmission mechanism and facilitates its fixation.

[0049] See Figure 2 The sidewall 24 of the moving space 22 is annular, and an upper connecting plate 23 is provided at the upper end of the sidewall 24. An entrance is provided in the middle of the upper connecting plate 23, and the gap on the moving device 4 is located inside the projection of the entrance.

[0050] The ring-shaped garbage bag material moves downward from the upper end of the ring sidewall 24 as the inlet for the garbage bag material. To ensure that the garbage bag material can pass through the moving device 4, the gap on the moving device 4 is located inside the inlet projection; that is, the ring projection of the inlet encloses the gap inside. The moving device 4 is vertically set, and the main drive wheel 44 and the auxiliary drive wheel 45 are both set laterally. The gap is vertical, and the garbage bag material partially passes through the gap. The two sides of the garbage bag material partially abut against the main drive wheel 44 and the auxiliary drive wheel 45, respectively.

[0051] See Figure 1 The upper end of the upper shell 2 is connected to a cover 3, and the middle of the cover 3 is provided with a through hole for garbage to pass through.

[0052] The cover 3 can be installed to hide the annular groove 21 and the garbage bag material inside, avoiding external interference and preventing foreign objects from entering and interfering with the output of the garbage bag material.

[0053] See Figure 1 A trash can device includes the aforementioned trash bag feeding mechanism, and also includes a lower housing located below the upper housing.
