Description

 Electronic cigarette injection needle Technical field

 The invention relates to the field of electronic cigarette processing equipment, in particular to an electronic cigarette oil injection needle.

Background technique

Because smoking is harmful to health and causes environmental pollution, smoking is now banned in most public places. However, for smokers with a long history of smoking, it is very difficult to quit smoking, so e-cigarettes came into being. In the electronic cigarette, the smoke oil is stored in the oil storage cotton of the atomizer, and the glass wool tube for oil extraction is wrapped in the middle of the oil storage cotton, and the oil oil of the oil storage cotton is realized by a heating device (such as a heating wire). For the purpose of heating, the smoke generated after heating is sucked out by the user from the mouthpiece.

In the production of electronic cigarettes, the smoke oil is injected into the atomizer through a syringe and adsorbed onto the oil storage cotton. The smoke oil flows out from the tip of the injection needle and comes into contact with the oil storage cotton and is adsorbed thereon, and gradually diffuses to the entire oil storage cotton by penetration. However, the smoke oil flows out from the needle tip of the injection needle and has a small contact area with the oil storage cotton, and the diffusion speed in the oil storage cotton is also slow, so that the oil injection speed of the syringe needs to be controlled within a small range, otherwise it is prone to occur. Oil leakage and other problems, it is difficult to achieve automated production of e-cigarette oil injection process, which is not conducive to the improvement of e-cigarette productivity .

Summary of the invention
