A mosquito net retractable device

Abstract

The invention discloses a mosquito net folding and unfolding device. The mosquito net folding and unfolding device comprises a shell (1) with an opening in the bottom, wherein a folding and unfolding device used for folding and unfolding a mosquito net by virtue of a three-axis part is arranged in the shell (1), and the folding and unfolding device corresponds to the opening. The mosquito net folding and unfolding device has the advantages of ingenious structural design and high practicability, the mosquito net can be automatically folded and unfolded by adopting the mosquito net folding and unfolding device, the mosquito net is prevented from being wound, and using reliability of the mosquito net is improved.

Description

technical field [0001] The invention relates to a retractable device, in particular to a mosquito net retractable device. Background technique [0002] Whenever summer comes, in order to prevent mosquito bites, people often use many methods for anti-mosquito treatment. The existing common anti-mosquito treatment mainly uses two methods: drugs and mosquito nets. Although drug treatment can kill mosquitoes, However, drugs often also cause a certain degree of harm to the human body. For the health of the family, many families have adopted a mosquito net to prevent mosquitoes. However, because the mosquito net must be built with brackets around the bed, it is inconvenient to build the mosquito net. At the same time, it also takes up space in the room. And, also extremely inconvenient for the folding of mosquito net. In order to solve such problems, people have studied retractable mosquito nets. [0003] In CN203016388U, disclose a kind of utility model patent called " ceiling...

AI Technical Summary

Problems solved by technology

[0003] In CN203016388U, a utility model patent called "top-suction mosquito net" is disclosed. Although the top-suction mosquito net of this structure can roll up the mosquito net by the reel, the structure cannot release the mosquito net.

Because, because the mosquito net itself is lighter in weight, when the motor rotates forward to collect the mosquito net, the mosquito net cannot be tightly wound on the reel, so that when the motor reverses and puts down the mosquito net, the reel will idle and cannot release the mosquito net. During the idling process, winding between the reel and the mosquito net will occur. Once the winding is too tight, it will cause a short circuit of the motor and damage the entire device.
