Description

Electronic cigarette

Technical Field

The utility model belongs to the technical field of the electron cigarette, specifically speaking is a good electron cigarette of waterproof performance.

Background

Electron cigarette frock principle: the electronic cigarette controls the output quantity and the working state of smoke through a high-tech silicon chip and an airflow inductor, nicotine is atomized, a solution containing nicotine and essence is atomized into particles, and the particles are absorbed through the lung and simultaneously spit out simulated smoke. The cigarette does not contain tar and other harmful components in the cigarette, and does not produce second-hand smoke and can not be diffused or detonated in a closed space; the traditional cigarette is ignited by tobacco leaves or tobacco, and harms the health of smokers and non-smokers.

When the air is sucked, high-speed air flow is formed in the sensor, the air flow sensor senses the suction of the oral cavity of a person, so that the air flow sensing switch is triggered to be turned on, and the product starts to enter a working state. The central processing unit controls the execution unit to work through calculation and measurement, and the atomizer is controlled by the central control unit and achieves atomization in different degrees according to the degree of the oral cavity suction force. The atomizer is composed of a high-frequency oscillation circuit and an electric heating wire, in the atomizer, high-purity electronic cigarette liquid enters an atomizing chamber after being pressurized by an ultramicro atomizing pump, is atomized into fog drops of about 0.5-1.5um in a vibration field of high-frequency ultrasonic waves in a critical mode, and is dispersed into an aerosol form by matching with inhaled air flow, so that steam fog simulating smoke is formed, the appearance of the aerosol is similar to that of a cigarette, and the aerosol is actually fog. The critical atomization condition is that the surface tension of the liquid is reduced to the most easily atomized degree by heating, and the temperature of common smoke (50-60 ℃) is simulated at the same time of simulating smoke.

Meanwhile, a green indicator light at the front end of the electronic cigarette is turned on to simulate cigarette end fire light, and the electronic cigarette is in a working state. When stopping breathing in, the air current in the sensor disappears, and air current sensing switch closes, and circuit board IC treater stop work, atomizer stop work, and the green of electron cigarette front end indicates for going out.

The electronic cigarette uses an airflow sensor (also called a microphone) to sense negative pressure formed by the air suction of a person, and then a heating wire is started to heat atomized tobacco tar. The airflow sensor is a key component for starting the electronic cigarette, because the smoke channel and the air suction channel are shared, part of smoke can flow back along the smoke channel after being condensed and can be left on the PCBA, the smoke oil contains nicotine and is alkaline, the PCBA and the airflow sensor above the PCBA can be corroded, once the airflow sensor is damaged, the heating wire cannot be normally started, the electronic cigarette is easily damaged, and the service life of most of the airflow sensor is only a few days or even shorter.

The traditional mode of handling uses three proofings lacquer spraying on the circuit board, and three proofings lacquer can form certain protection to other components and parts on the circuit board, but because of three proofings lacquer spraying is thick, can't handle baroceptor, if at the thicker coating of baroceptor spraying, then can seriously influence its sensitivity, cause the unable start-up of product.
