Description

Technical Field

[0001] The utility model relates to the technical field of electronic cigarettes, and in particular to a circuit structure of an electronic hookah. Background Art

[0002] Electronic hookah is an electronic product that imitates traditional hookah, which combines the characteristics of electronic cigarettes and hookah. Electronic hookah is usually powered by batteries and has a built-in heating element that can heat the tobacco material and convert it into smoke.

[0003] In the field of traditional hookahs, the main heating method is to directly burn charcoal to heat the bowl of the hookah. This method places charcoal above the bowl, and the heat generated by the burning of charcoal is transferred to the tobacco through the bowl, so that the tobacco produces smoke after being heated. However, since the above traditional hookah heating method relies on the combustion of charcoal and other materials to generate heat, and this heat source is not easy to control, the heating efficiency is relatively low; and the charcoal combustion process will release carbon monoxide, smoke and other harmful substances, and long-term inhalation of these substances may have a negative impact on human health. At the same time, the traditional hookah lacks an effective temperature control mechanism, making it difficult to control the heating state of the tobacco, and it is easy to overheat or underheat, which will cause the tobacco to burn or produce a bad taste. In addition, the traditional hookah mainly relies on the heating method of charcoal combustion, which is relatively single, making the heating effect of the tobacco uneven, affecting the taste of the smoke, and not conducive to the user experience.
