Description

Technical Field

[0001] The utility model relates to the technical field of trash can structures, and particularly relates to a packing power driving mechanism for an automatic packing trash can. Background Art

[0002] With the popularization of the fast-paced lifestyle, people are increasingly pursuing the convenience of life. The automatic packing intelligent trash can is a modern household device that integrates advanced mechanical and electronic technologies, aiming to simplify the daily garbage disposal process and improve the quality of life of users. This intelligent trash can usually has automatic compression, automatic packing and other automation functions. The core is to use the cooperation of a motor and a push rod to realize the bag mouth of the garbage bag, and use heat sealing technology to complete automatic packing.

[0003] For example, the patent document with the publication number of CN210708997U provides an automatic packing trash can, including: a bucket lid; a first lead screw rotatably installed in the bucket lid; a second lead screw rotatably installed in the bucket lid, and the second lead screw is arranged perpendicular to the first lead screw; a first pressure rod threadedly installed on the first lead screw; a second pressure rod threadedly installed on the second lead screw, the second pressure rod is slidably sleeved on the first pressure rod, and the second pressure rod is arranged perpendicular to the first pressure rod; a first motor fixedly installed in the bucket lid, and the first motor is adapted to the first lead screw; a second motor fixedly installed in the bucket lid. The automatic packing trash can provided by the utility model has the advantages of being able to quickly gather and seal and fuse the garbage bag, being able to avoid the sanitation problems brought by manual packing, and ensuring the sealing and fusing effect.

[0004] In the above-mentioned existing solution, single-sided pressure rods in two directions are adopted, that is, each pressure rod is only connected to the driving mechanism or the transmission mechanism at one end. Since the pressure rod is usually made of plastic, has a relatively long length, and has a hollow structure in the middle with only thin walls on both sides, this causes the pressure rod to be prone to shrinkage deformation and bending during the sliding process, and thus cannot move parallel along the established direction. That is, the pressure rod and the corresponding connected lead screw are not perpendicular. The pressure rod with only one-end transmission has a large friction or resistance when pushing the rod; on the other hand, each pressure rod moves in cooperation with a lead screw and a motor separately. The movement coordination of the two pressure rods requires the two motors to have a high time-precision coordinated cooperation, otherwise the synchronous movement cannot be completed, and the coordination difficulty is relatively high; moreover, the two motors operate independently, which will also cause a large loss of battery energy, resulting in a short battery life. Summary of the Invention
