Electronic cigarette capable of automatically preheating after prejudgment of smoking action and control method thereof

Abstract

The invention discloses an electronic cigarette capable of automatically preheating after prejudgment of a smoking action and a control method thereof. The electronic cigarette comprises a liquid storing cavity, a battery, an atomizing device, a control circuit and a preheating element, wherein electronic components of the control circuit include a gravity sensor, a temperature detection unit anda microcontroller; the control circuit is configured in the following way: when the gravity sensor senses that the electronic cigarette generates a motion change of a certain amplitude, the microcontroller prejudges the motion change as a smoking action, meanwhile the microcontroller determines whether tobacco juice is required to be preheated or not according to a real-time temperature value detected by the temperature detection unit; when the smoking action is detected and the preheating is required at the same time, the preheating element is controlled to heat in advance; and after heatingfor preset heating duration or to a preset target temperature value, the electronic cigarette enters a standby smoking state. The electronic cigarette has the beneficial effects that the electronic cigarette can automatically recognize the smoking action without the need of manual operation, and automatically performs preheating before smoking, so that the electronic cigarette can produce smoke easily at a low temperature.

Description

technical field [0001] The present invention relates to the technical field of electronic cigarette preheating, and more specifically, the present invention relates to an electronic cigarette that is automatically preheated after predicting a smoking action and a control method thereof. Background technique [0002] E-cigarettes usually heat and atomize liquid substances or pasty substances such as medicines and smoke liquids to emit aerosols or smoke for use by smokers. Since the smoke emitted by electronic cigarettes is not directly burned by an open flame like tobacco, it avoids Smoke tar and many harmful particles are produced, so the application of electronic cigarettes is popularized. [0003] Existing electronic cigarettes generally include smoke liquid and a heating wire for atomizing the smoke liquid. The smoke liquid is usually stored in a liquid storage chamber. When atomizing, the smoke liquid in the liquid storage chamber penetrates or conducts to the heating wi...

AI Technical Summary

Problems solved by technology

When the e-cigarette is turned on and used, there is usually no preheating control method and program to preheat the e-cigarette, especially when the e-cigarette is in the cold winter season or in a cold area with high altitude and high latitude, the smoke liquid of the e-cigarette or E-liquids and liquid substances containing drugs are easy to reduce viscosity and fluidity at low temperature, so that the e-liquid or drugs are not easy to penetrate or flow to the heater for atomization, which makes it difficult to effectively inhale the smoke when the e-cigarette is just started
