Description

A portable air-heated hookah paste aerosol generator Technical Field

[0001] The present invention relates to the technical field of electronic cigarettes, and in particular to a portable air-heated hookah paste aerosol generator. Background Art

[0002] Shisha, also known in Arabic as shisha, is a traditional part of Arab culture and life. Its tobacco is made from fruit and contains very low levels of tar and nicotine.

[0003] Currently, traditional Arabic hookahs are mostly heated using traditional charcoal heating. Integrated hookah electronic cigarettes heat the hookah paste through combustion or contact heating. Because the high temperature required to generate aerosols can lead to a large temperature difference between the inside and outside, resulting in a poor user experience. Traditional hookahs require an external water container, which is inconvenient to carry and difficult to smoke outdoors. Repeated heating using a folding airway results in a large, awkwardly held integrated hookah electronic cigarette. The process is particularly cumbersome, requiring at least 20 minutes to prepare each time, and changing the water in the hookah bottle is a tedious operation.

[0004] In summary, how to effectively solve the problems of insufficient heating of hookah tobacco paste, bulky size, and difficulty in carrying, is an urgent problem that technicians in this field need to solve.

[0005] Summary of the Invention

[0006] The object of the present invention is to provide a portable air-heated hookah paste aerosol generator, which enables hookah paste to be fully heated, is compact and easy to carry.

[0019] The present invention provides a portable air-heated hookah paste aerosol generator comprising a top cover, a heating element assembly, a receiving chamber, an upper cover, an air inlet channel, an air outlet channel, a water tank, and a control device. The top cover has an air inlet through which air enters. The heating element assembly is mounted on the top cover, and the receiving chamber is connected to the lower end of the heating element assembly. The hookah paste is loaded into the receiving chamber, and the heating element assembly heats the hookah paste and the receiving chamber.

[0020] The upper cover has an air inlet and an air outlet, and the air inlet of the upper cover is connected to the lower end of the accommodating chamber. The bottom of the water tank has a drain outlet, which is equipped with a sealing plug. After removing the sealing plug, water can be added and drained. The water tank lid is provided with an inlet end and an outlet end. The air inlet channel is connected to the air inlet and inserted into the inlet end of the water tank lid. The end of the air inlet channel is deeply immersed in the filtered water. The filtered water in the water tank can filter aerosols, and the aerosols can also be cooled by passing through the liquid in the water tank. The air outlet channel is connected to the air outlet and inserted into the outlet end of the water tank. The end of the air outlet channel does not penetrate into the filtered water and is located above the liquid surface.

[0021] The heating element assembly includes an airflow heater and a preheating heater. The airflow heater is located at the top and heats the airflow, causing the hookah to generate aerosol. The hookah paste generates aerosol after heating. The aerosol is then inhaled by the user into the water tank for filtration and then extracted. The airflow heater can specifically be a honeycomb heating element. The preheating heater is located at the bottom and wrapped around the receiving cavity. The preheating heater is an auxiliary heating element that preheats the receiving cavity circumferentially, allowing the hookah paste to be preheated faster, allowing the user to inhale faster.

[0022] The control device is connected to the water tank and electrically connected to the heating element assembly. After the tobacco paste is loaded, the machine is turned on. After turning on, the control device can control the opening and closing and heating time of the airflow heater and the preheating heater according to the settings. According to the characteristics of different hookah pastes, the temperature range can be set to improve the user's smoking experience.

[0023] The specific operation process includes: loading the hookah paste into the holding chamber. After the hookah paste is filled, the control device controls the aerosol generator to start and control the heating time and heating temperature, for example, preheating for 15 seconds before inhalation. When the user inhales, air enters through the air inlet of the upper cover and the air flow heater heats the air. The heated air enters the preheated holding chamber, heating the hookah paste to produce aerosol. The aerosol enters the water tank through the air inlet channel connected to the air inlet of the upper cover. The aerosol in the water tank is filtered by the water and rises into the air outlet channel connected to the outlet end of the box cover, and the aerosol is delivered for inhalation by the user.

[0024] The portable air-heating hookah paste aerosol generator provided by the present invention heats the hookah paste simultaneously with the airflow heater and the preheating heater, so that the hookah paste can be preheated and heated faster, so that the hookah paste can be fully heated, and the user can inhale faster, thereby improving the user's smoking experience; the water tank and the smoke machine are integrated to form a portable hookah all-in-one machine, which does not require an additional external water tank, is compact in size, easy to hold and carry, and can be conveniently used by users outdoors.
