Abstract
Description
Technical Field
[0001] The utility model relates to the field of electronic cigarettes, in particular to an atomizer for preventing backflow. Background Art
[0002] An electronic cigarette is a smoking device that generates smoke by driving an atomizer to heat the smoke oil. Specifically, the air intake of the electronic cigarette is in a conductive state, and then the user inhales to deform the diaphragm in the microphone head of the electronic cigarette. The deformed diaphragm is connected to the GND on the circuit board and is conductive to generate smoke.
[0003] However, the existing driving mist for electronic cigarettes still has the following problems during use:
[0004] When the existing electronic cigarette is used, the liquid nicotine in the cigarette cartridge can be converted into mist through the atomizer, so that the user has a feeling similar to smoking when inhaling. The atomized smoke generated by heating will gradually cool down to form condensate during the movement along the air flow channel inside the electronic cigarette. Since the condensate contains components such as tobacco oil and water, the condensate will flow back into the atomizer core of the electronic cigarette atomizer, which will cause the atomizer core to have a bad taste, make oil frying noises, and even damage the atomizer, thereby affecting the normal use of the electronic cigarette. Therefore, it is very necessary to involve an atomizer that prevents backflow in the existing electronic cigarette field. Utility Model Content
[0005] In order to make up for the deficiencies of the prior art, the existing condensate flows back into the atomizer core of the electronic cigarette atomizer, which will cause the atomizer core to have a bad taste, make abnormal noises of oil frying, and even damage the atomizer, thereby affecting the normal use of the electronic cigarette. The utility model proposes an atomizer that prevents backflow.
