Description

Technical Field

[0001] The present invention relates to the technical field of trash cans, and particularly to a bag-opening device with a chute-type swing rod telescoping function and an intelligent trash can. Background Art

[0002] Trash cans are essential items in daily life and are also one of the carriers for implementing garbage classification. 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 bag 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. Summary of the Invention

[0004] In order to solve the above technical problems, the present invention provides a bag-opening device with a chute-type swing rod telescoping function and an intelligent trash can. By setting the swing rod as a chute-type telescoping structure, the swing rod can be telescoped during the swinging process to improve the sealing stability of the garbage bag.

For those of ordinary skill in the art, without creative efforts, other drawings can be obtained based on these drawings, and other embodiments can also be obtained.

[0052] In the prior art, as Figure 1 shown, the device for opening the mouth of a garbage bag includes an inner barrel rack 15 in a trash can, a swing rod mechanism mounted on the inner barrel rack 15, 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 an adhesive strip 19 is mounted on the cross bar 1; the bottom of the swing rod 2 is hinged to the bottom of the inner barrel rack 15; when the top of the swing rod 2 swings from one side inside the trash can to the other side inside the trash can driven by a pull rod 9, the adhesive strip 19 on the cross bar 1 contacts and adsorbs the mouth of the garbage bag, and 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 adhesive strip 19 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.

[0053] To solve the above problems, as Figures 2 to 4As shown in the figure, this embodiment provides a bag-opening device with a sliding groove 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. It includes: a cross bar 1, a swing rod 2 and a connecting rod 6. The cross bar 1 is used to install a rubber strip 19 for adsorbing the bag mouth of the garbage bag. The swing rod 2 includes a first swing rod 3, a second swing rod 4 and a sliding groove mechanism 5. The lower end of the first swing rod 3 and the upper end of the second swing rod 4 are stacked along the length direction of the swing rod 2. The first swing rod 3 and the second swing rod 4 are slidably connected through the sliding groove mechanism 5.
