Under the condition of high cost performance, improving the convenience of use is an increasing demand. Most of the existing trash cans require manual bag replacement and sealing. The vast majority of intelligent trash cans on the market only achieve induction opening of the lid, or are semi-automatic products that require manual assistance to complete the bag replacement work.

[0003] Currently, for trash cans on the market that can automatically replace and seal bags, the device used to open the bag mouth of the garbage bag generally includes an inner barrel frame inside the barrel, a swing rod mechanism installed on the inner barrel frame, and a driving mechanism for driving the swing rod mechanism to operate; the swing rod mechanism is provided with a swing rod and a cross bar. The two ends of the cross bar are fixed to the top of the swing rod, and a rubber strip is installed on the cross bar; the bottom of the swing rod is hinged to the bottom of the inner barrel frame; when the top of the swing rod swings from one side inside the barrel to the other side inside the barrel, the rubber strip on the cross bar contacts and adsorbs the bag mouth of the garbage bag, and when the top of the swing rod swings back from the other side inside the barrel to one side inside the barrel, the rubber strip on the cross bar drives the bag mouth of the garbage bag to open. Since the length of the swing rod is fixed during the swinging process, when the garbage in the trash can is too much and exceeds the height of the swing rod, the garbage bag cannot be sealed.

Obviously, the drawings in the following description are only some embodiments of the present invention. For those of ordinary skill in the art, without creative efforts, other drawings can be obtained according to these drawings, and other embodiments can also be obtained.

[0049] In the prior art, as Figure 1 shown, the device for opening the mouth of a garbage bag includes an inner barrel frame 19 inside the trash can, a swing rod mechanism installed on the inner barrel frame 19, and a driving mechanism for driving the swing rod mechanism to operate; the swing rod mechanism includes a cross bar 1 and a swing rod 2. Both ends of the cross bar 1 are fixed to the top of the swing rod 2, and a rubber strip 23 is installed on the cross bar 1; the bottom of the swing rod 2 is hinged to the bottom of the inner barrel frame 19; when the top of the swing rod 2 swings from one side inside the trash can to the other side inside the trash can, the rubber strip 23 on the cross bar 1 contacts and adsorbs the mouth of the garbage bag. When the top of the swing rod 2 swings back from the other side inside the trash can to one side inside the trash can, the rubber strip 23 on the cross bar 1 drives the mouth of the garbage bag to open. Since the length of the swing rod 2 is fixed during the swinging process, when the garbage in the trash can exceeds the height of the swing rod 2, the garbage bag cannot be sealed.

[0050] To solve the above problems, as Figures 2 to 4As shown in the figure, this embodiment provides a bag-opening device with a slide-rail type swing rod telescoping structure, which is used to be installed in a trash can to automatically open the bag mouth of a garbage bag.

When the swing rod 2 swings from a first position inside the trash can to a second position inside the trash can, the rubber strip 23 on the cross bar 1 contacts and adsorbs the bag mouth of the garbage bag. When the swing rod 2 swings back from the second position inside the trash can to the first position inside the trash can, the rubber strip 23 on the cross bar 1 drives the bag mouth of the garbage bag to open. During the process of the swing rod 2 swinging from the first position inside the trash can to the second position inside the trash can, the length of the swing rod 2 first increases and then decreases.

[0051] In this embodiment, when the rubber strip 23 on the cross bar 1 adsorbs the bag mouth of the garbage bag to open it, the sliding rod 9 moves to the upper end of the chute 8, so that the overlapping part of the first swing rod 3 and the second swing rod 4 is longer. At this time, the swing rod 2 is in a contracted state; when the cross bar 1 moves from this side towards the approximate middle part of the trash can, the overlapping part of the first swing rod 3 and the second swing rod 4 gradually shortens. At this time, the swing rod 2 gradually extends; when the cross bar 1 moves from the approximate middle part of the trash can to the other side, the overlapping part of the first swing rod 3 and the second swing rod 4 gradually increases. At this time, the swing rod 2 gradually shortens; when the rubber strip on the cross bar adsorbs the bag mouth of the garbage bag to close it, the sliding rod 9 moves to the upper end of the chute 8, and the overlapping part of the first swing rod 3 and the second swing rod 4 is longer. At this time, the swing rod 2 is in a contracted state; the swing rod 2 is set as a slide-rail type telescoping structure, so that the swing rod 2 can be telescoped during the swinging process. When there is more garbage in the trash can, the swing rod 2 can extend to make the cross bar 1 cross the obstacle to improve the sealing stability of the garbage bag; this bag-opening device with a slide-rail type swing rod telescoping structure realizes automatically opening the bag mouth of the garbage bag, with a lower cost, does not require manual bagging, and has good flexibility.
