Title: AIR FLOW SENSOR AND ATOMIZER
Abstract:
Provided is an air flow sensor (100) and an atomizer, comprising: a hollow housing (110) and at least two sensing units (120) disposed inside the hollow housing (110), wherein each sensing unit (120) comprises a first friction layer (121) and a second friction layer (122); The first friction layer (121) is fixed on an inner wall of the hollow housing (110), and the second friction layer (122) is disposed opposite to the first friction layer (121); An air flow passage is formed inside the hollow housing (110), and an air flow inside the air flow passage acts on the first friction layer (121) and/or the second friction layer (122), so that the first friction layer (121) and the second friction layer (122) rub against each other; The at least two sensing units (120) form a sealed space, and the sealed space is not in communication with the airflow passage. The airflow sensor (100) and the atomizer solve the problem that the accuracy of the airflow sensor in the prior art is easily affected by the moisture factor, the component damage cannot be promptly reminded, and the production cost is high.
