Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to an automatic closing structure for a garbage can. Background Art

[0002] Currently, the sealing and packing mechanisms of most smart trash cans on the market use one or two pressure rods to close the garbage bag to one side or corner of the garbage inlet, and then the sealing device and the pressure rod cooperate to complete the sealing and packing. However, the pressure rod is prone to bending and deformation or even tilting and getting stuck during operation, which not only affects the closing quality of the garbage bag and causes uneven sealing of the garbage bag, but also causes closing failures, making it impossible to close the garbage bag.

[0003] To this end, relevant technical personnel have conducted research and development. For example, the utility model patent with Chinese patent number CN201821767136.5 discloses a garbage bag closing device and an intelligent trash can. It uses flexible materials to close the mouth, which can greatly reduce the processing and assembly accuracy requirements of various parts and components. The flexible closing material is connected to the drive device as a transmission part, and also acts as an actuator to perform the action of closing and sealing the bag, which greatly simplifies the mechanical transmission structure.

[0004] However, the flexible belt is driven by the rotation of the gear of the flexible closing mechanism to tighten or open the sealing device. However, the flexible belt is only elastic. When it is not tightened, it is long, which will block the opening of the trash can. It is easy to get stuck during the tightening process. Moreover, the elastic force generated by the flexible belt can only be achieved by the number of turns of the driving gear of the flexible closing mechanism. If the driving gear of the flexible closing mechanism rotates too many times, the flexible belt will break. If the driving gear of the flexible closing mechanism rotates too few times, it will easily cause the garbage bag to be unevenly folded. In addition, the driving gear of the flexible closing mechanism is round, which means that the closing device can only be used on trash cans with round openings, and its scope of use is limited.

[0005] Therefore, further improvement is necessary. Utility Model Content

[0036] The driving wheel 9 rolls directly on the track 2 , or the driving wheel 9 is transmission-connected with a positioning wheel 10 , and the positioning wheel 10 rolls along the track of the track 2 .

[0037] That is, the driving wheel 9 can roll directly on the track 2 through the drive of the driver 8, so that the sliding drive group 3 can slide on the track 2, or the driving wheel 9 drives the positioning wheel 10 to roll on the track 2 through the drive of the driver 8, so that the sliding drive group 3 can slide on the track 2.

[0045] In this embodiment, the flexible closing member 4 is preferably a metal rope, one end of which is fixedly connected to the cover plate 13 or the sliding frame 7 , and the other end is automatically rolled up on the tensioner 6 .

[0046] A top plate 14 is provided on the top of the barrel cover 1, and a bottom plate 15 is provided on the bottom.

The track 2 is arranged on the barrel cover 1 or the bottom plate 15, and the barrel cover 1 or the bottom plate 15 is also provided with a position sensor 17 corresponding to the sliding drive group 3.

[0047] In this embodiment, the track 2 is set according to the shape of the cover 5 of the bucket cover 1. Therefore, no matter what shape the cover 5 is, the sliding drive group 3 can slide along the track of the cover 5 of any shape, and make the flexible closing member 4 close the garbage bag opening on the cover 5. Compared with the prior art that the cover 5 is round or square, this embodiment not only provides better design creativity for the appearance of the garbage can, but also improves the flexibility of the sliding drive group 3 and the flexible closing member 4 during work, and at the same time ensures that the flexible closing member 4 can cover the cover 5. In addition, the bottom plate 15 can also block the position below the track 2, the sliding drive group 3, and the flexible closing member 4 to prevent foreign matter from entering.

[0048] In the present embodiment, the shapes of the cover opening 5 and the bottom plate opening 16 are both quadrilaterals, with arc-shaped transitions at the corners. The shape of the track 2 is the same as that of the cover opening 5 and the bottom plate opening 16. The track 2 is fixedly arranged on the bottom plate 15, and the sliding drive group 3 is suspended above the track 2 as a whole. At the same time, two positioning wheels 10 arranged separately are positioned on the left and right sides of the track 2 and slide, thereby preventing the track 2 and the sliding drive group 3 from blocking the cover opening 5 and the bottom plate opening 16. The top plate 14 is hinged to flip over the top of the barrel cover 1, and opens or closes the cover opening 5 and the bottom plate opening 16 when flipping.

[0049] The barrel cover 1 is also provided with a sealing device, and the flexible closing member 4 closes the opening of the garbage bag when the sliding drive group 3 slides, and the sealing device seals the garbage bag after it is closed.

[0050] In this embodiment, the sealing device preferably adopts an electric heating plastic sealing method, and a heating wire heat plastic sealing method is more preferred, which can complete the plastic sealing and fusing of the garbage bag at one time. For example, a hot melt device disclosed in Chinese Patent No. CN201810624090.X can be used.

[0051] Since the flexible closing member 4 is a metal rope, it will not be damaged due to the high temperature of the sealing device during operation, and has a long service life and stable operation.

[0052] In addition, the position sensor 17 is arranged on the barrel cover 1, which can sense the sliding position of the sliding drive group 3, so that the flexible closing member 4 can effectively close the garbage bag and allow the sealing device to seal the garbage bag.

[0053] The above is a preferred embodiment of the utility model, which shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments, and the above embodiments and descriptions are only for explaining the principle of the utility model.
