Tobacco heater

Abstract

The invention discloses a tobacco heater. The tobacco heater comprises a shell, a controller, a central heater arranged in the shell, an external heater and a power supply for supplying power, the central heater comprises a heating needle, the external heater comprises a heating cup, the heating cup sleeves the heating needle, a cavity for inserting tobacco is formed between the heating cup and the heating needle, the controller comprises a first control part for controlling the central heater to be started and stopped and a second control part for controlling the external heater to be startedand stopped, the central heater is connected with the first control part, and the external heater is connected with the second control part; a heating mode of independently controlling internal heating and external heating is adopted, multiple heating modes such as internal and external simultaneous heating, internal and external alternate heating and internal and external independent heating canbe achieved, a user can freely select the heating modes according to the types of the smoke cartridges or the requirements of the user, and therefore the tobacco heater can better adapt to the formula characteristics of various smoke cartridges and the personalized requirements of the user.

Description

technical field [0001] The invention relates to the technical field of smoking utensils, in particular to a tobacco heater. Background technique [0002] Compared with traditional combustion cigarettes, low-temperature non-burning cigarettes produce less harmful substances during smoking, so they are more and more popular among smokers. In the process of smoking low-temperature non-burning tobacco, it is necessary to use an external heating device, that is, a low-temperature non-burning smoking set to bake the tobacco leaves. The heating quality of the low-temperature non-burning smoking set will directly affect the smoking effect and smoking experience. [0003] At present, there are mainly mixed type and flue-cured pods. Each type of pod is divided into tobacco flavor, mint flavor, fruit flavor and other flavors. Different pods have different temperature requirements, and the temperature is too high or too low. It is very good for the formula of the pod itself to be fully...

Problems solved by technology

[0003] At present, there are mainly mixed type and flue-cured pods. Each type of pod is divided into tobacco flavor, mint flavor, fruit flavor and other flavors. Different pods have different temperature requirements, and the temperature is too high or too low. It is very good for the formula of the pod itself to be fully volatilized, and the user's own habits also have personalized requirements for the temperature; while the existing low-temperature non-burning smoking appliances are mainly divided into three types: central heating, external heating and internal and external heating. And external heating belongs to one-sided heating, and the baking of the pods is not uniform and sufficient. The internal and external heating is heated inside and outside at the same time, which can ensure that the pods are fully baked. Baking produces peculiar smell, and at the same time, it cannot meet the individual needs of users for different tastes

In addition, the existing internal and external heating elements all use ceramic needles. The ceramic itself has low precision, difficult molding, high cost, and prone to problems of uneven heat conduction.

[0004] Therefore, how to solve the problem of insufficient heating or excessive temperature of the pod when using the low-temperature non-combustible smoking appliance is a technical problem that those skilled in the art need to solve at present.
