BACKGROUNDThe disclosure relates to the field of electronic cigarettes, and more particularly, to a smoke generation and filtration device, and to a hookah comprising the same.
A conventional hookah includes a smoke generation and filtration device. The smoke generation and filtration device typically includes a heating component and a smoke filtration component. The smoke filtration component is configured to filter out the toxins from the smoke. The heating component heats the tobacco material to generate smoke. The smoke is then passed through the smoke filtration component, discharged to a contact part, and ultimately inhaled by users.
In the conventional smoke generation and filtration devices, the heating component are usually located on the side or top of the smoke filtration component, resulting in excessive lateral dimensions of the smoke generation and filtration device. This is inconvenient for users in holding the smoke generation and filtering component while smoking. Moreover, the smoke enters the smoke filtration device from the side or top, leading to insufficient dissolution of harmful substances in the water.
Furthermore, the conventional hookahs are typically integrally formed, making it difficult to clean the smoke generation and filtration device. During smoking, the smoke generation and filtration device cannot be detached from the main body of the hookah, resulting in inconvenience in terms of usability and portability.
