Description

A cigarette heating device with display function

technical field

The utility model relates to an electric smoking system, in particular to a cigarette heating device with a display function.

Background technique

Different from the traditional smoking method of burning cigarettes with an open flame (the maximum temperature of the cigarette is about 900°C), since there is no open flame burning, no open flame baking (the temperature of the cigarette is about 180~400°C) the smoking method avoids high-temperature cracking and release The process of harmful components, the generation of harmful substances in smoke is much lower than the harmful substances produced by traditional cigarettes after burning, which has become a potential direction for the future development of the tobacco industry. Electric heating and non-burning cigarettes need to use heating elements to heat the cigarettes to volatilize the aroma substances, so as to obtain the feeling similar to smoking cigarettes. However, there are still some problems in the current cigarette heating device: 1) When heating the cigarette, the cigarette needs to be inserted into the heating device inside the cigarette heating device, but sometimes due to improper insertion, the cigarette is heated unevenly, which in turn affects the sensory quality of smoking . 2) Cigarette heating devices often affect user experience due to insufficient battery power.

When the cigarette is inserted, the surface of the cigarette contacts and reflects the infrared light emitted by the distance sensor, which indicates that the insertion depth of the cigarette is in place. In addition, since the first distance sensor and the second distance sensor interfere with both sides of the cigarette surface respectively, the respective distances between the first distance sensor and the second distance sensor and the cigarette surface can be obtained, and by comparing the distances between the two, thus Determine whether the heating plate is inserted into the center of the cigarette.

In order to display the remaining power of the battery on the display, to prompt the user. Further, the power supply device further includes a battery power detection module, and the battery power detection module is respectively connected to the rechargeable battery and the control module. When the power is low, the display screen will display a symbol to prompt charging or replacing the battery.

In order to display the heating temperature in the display to prompt the user. Further, the tobacco-curing chamber is also provided with a temperature sensor for detecting heating temperature, and the temperature sensor is connected with the control module.

Furthermore, a switch is also provided on the display, so that when there is no need to observe the status of the cigarette heating device with the display, it can be turned off in time to save power.

Further, the connection between the flue-cured chamber and the cavity is provided with a heat-insulating layer, and the shell of the flue-cured chamber is also provided with a heat-insulated layer, so as to reduce the impact of heat generated by the flue-cured chamber on the control module, battery and other components. damage to the device, and at the same time prevent the user from being overheated and scalded by the shell of the flue-cured chamber after long-term use, which improves the safety of the device.

Compared with the prior art, the beneficial effects of the utility model are:

The utility model sets the position detection device and the battery power detection module to judge whether the cigarette is inserted in the correct position and whether the power is sufficient, and reflects the information through the display, so that the user can obtain a better smoking experience.
