Description

Low temperature smoking set with brightness display function

technical field

The invention belongs to the field of low temperature smoke, and in particular relates to a low temperature smoke set with a brightness display function.

Background technique

Traditional cigarettes need to be ignited and burned by an open flame to generate tobacco smoke. Tobacco releases thousands of substances harmful to the human body during the process of high temperature and pyrolysis. The composition of substances, such as carbon monoxide, phenols, aldehydes, nicotine (nicotine), cigarette tar, etc., and the low-temperature smoking device that does not burn can effectively reduce the production of harmful substances and be healthier. At present, there are two types of low-temperature smoking sets on the market: central heating and surrounding heating. Both are powered by batteries to supply the heating element to heat up, heat the low-temperature cigarettes to a set temperature, and generate smoke for users to smoke.

Most low-temperature smoking devices use rechargeable lithium batteries to supply energy for the heating body. When the low-temperature smoking device is used for a period of time and the battery is exhausted, the user can take it to charge and continue to use it after it is fully charged. Under normal circumstances, when the low-temperature smoking set is in use, the heating time of each cigarette is fixed (set by the system in advance). In the state of cigarettes, they can usually smoke a dozen cigarettes, and then they need to be charged. However, consumers usually do not remember how many cigarettes they have smoked, so it is difficult for them to accurately grasp the charging time of the smoking set.

The Chinese Patent Application No. 201320635746.0 discloses an electronic cigarette with a power display device, and the Chinese Patent Application No. 201420622436.X discloses a power supply device and an electronic cigarette, both of which are arranged on the electronic cigarette. Several LED lights or indicator lights of the power level show the amount of power by the brightness of the LED lights or indicator lights. However, the way that the LED lights directly shoot on the outer surface of the smoking device is easy to cause glare and affect the user's experience.

SUMMARY OF THE INVENTION

The technical problem solved by the present invention is to provide a low-temperature smoking device with a brightness display function in view of the above-mentioned shortcomings of the electric power display of the existing low-temperature smoking device.
