Background technique

As people pay more and more attention to physical health and environmental safety, people realize that tobacco is very harmful to people's health. Therefore, products called "electronic cigarettes" have been produced.

Electronic cigarettes are also known as virtual cigarettes and electronic atomizers. It is a relatively common electronic product of simulated cigarettes, which mainly produces "smoke" by atomizing e-liquid. Compared with traditional cigarettes, electronic cigarettes have similar appearance and taste, and they are even better than ordinary traditional cigarettes. more flavors. However, the e-cigarette liquid or e-liquid does not contain harmful substances such as nicotine or tar. When cigarette consumers smoke this e-cigarette, they can avoid the intake of harmful substances, and can satisfy people's smoking habits, becoming a smoking cessation product or Substitutes for cigarettes. In addition, electronic cigarettes are atomized through e-liquid, and the solution containing e-liquid and flavor is atomized into particles, which are absorbed through the lungs and exhales simulated smoke without tar and other harmful components in cigarettes, and will not produce second-hand Smoke will not diffuse or linger in confined spaces, so more and more people use electronic cigarettes to replace traditional cigarettes.

The electronic cigarette is actually an atomizing device, that is, an aerosol generating device. The atomizing device in the prior art generally controls the electronic cigarette by setting a sensor near the air intake hole in the airflow channel to detect the user's smoking action. However, the atomizing device in the prior art has at least one of the following problems. The first is that the sensitivity of the sensor in the prior art is not high, and the user needs to pump more forcefully, so that the airflow in the airflow channel causes Changes in air pressure are detected by the sensor. Second, in the prior art, since the heating element is located in the airflow channel and the sensor is located between the heating element and the air intake hole, the user's suction may be hindered by the heating element, and the user will be tired. Third, the atomizing device in the prior art can only generate airflow by means of suction, and cannot generate airflow automatically, which limits the scope of application. Fourth, the mist outlet of the atomizing device in the prior art is set horizontally, so that the mist can only be discharged horizontally, and the use angle is limited, thus limiting the application scope of the atomizing device.

Chinese patent CN109330031A discloses an electronic cigarette, including an atomizing component, a battery component, a controller, an air pressure sensor, and the like. Chinese patent CN105935155A discloses an electronic cigarette, which includes a heating element, a sensor and an airflow channel, and the heating element is arranged in the airflow channel. The above two patents are sensors to detect the user's smoking action to control the on/off of the electronic cigarette, and the airflow can only be generated by the method of smoking, and the airflow cannot be automatically generated.
