Description

Technical Field

[0001] The invention relates to the technical field of hookah inhalation devices, and in particular to a heating device for hookah inhalation devices. Background Art

[0002] Hookah inhalation devices, also known as hookahs, hookahs, hookah pots or hookah pipes, are popular among smokers because they not only retain the mellow aroma of tobacco but also filter out other impurities with water. Existing hookahs have different structures and shapes. Usually, the hookah structure is vertical, which is connected from top to bottom by a smoke pot, a tray, a smoke pipe, a water container and a mouthpiece. The smoke from the tobacco burning in the smoke pot is introduced into the water container through the smoke pipe. After the impurities in the smoke are filtered by water, it is inhaled into the mouth of the user through the mouthpiece. When in use, the tobacco paste is generally placed in the accommodating cavity at the lower part of the tobacco pot, and then tinfoil is placed on the upper part of the tobacco pot, and a plurality of holes are opened in the tinfoil, and charcoal is placed on the tinfoil and ignited to burn the tobacco paste. With such a structure, when replacing the tobacco paste, the tinfoil and charcoal need to be taken out first, and the ashes after the burnt are poured out, and the replacement process is relatively troublesome; in addition, the fire supply method of the above structure cannot control the size of the charcoal fire, resulting in the inability to control the burning speed of the tobacco paste. As long as the charcoal fire exists, the tobacco paste in the tobacco pot is in a burning state until it is burned out, and the user cannot use it after a period of time, which brings great inconvenience to the user; and, the charcoal fire is directly placed on the tinfoil, which is prone to falling, posing certain safety hazards.

[0003] In recent years, there have been a variety of schemes for using electric heating devices to replace traditional charcoal fire heating methods in hookah inhalation devices. For example, the Chinese invention patent application with application number 202210881421.4 discloses a preheating hookah heating device, including a power supply drive device and a heating element, the power supply drive device includes a shell and a power supply drive module installed in the shell, the heating element includes a heating part, the heating part is installed outside the bottom shell of the shell at a distance, and a heating cavity is formed between the heating part and the bottom shell, the side wall of the heating cavity has an air inlet hole connected to the outside, the heating part is provided with a through vent hole, the power supply drive module drives the heating part to generate heat, the hookah heating device can be installed above the smoke container and cover the entrance of the smoke container, the heating part extends into the smoke container and can heat the smoke generating medium in the smoke container, when smoking, the air enters the heating cavity through the air inlet hole and is heated by the heating element, and the heated air passes through the vent hole into the smoke container. However, this solution only relies on the side air intake, and the air intake volume is relatively small, which can easily cause poor airflow during the user's continuous smoking process. In addition, although the device has an electronic temperature control system, the tobacco paste is easily overheated, and the tobacco paste is burnt, resulting in a spicy taste.

[0004] Based on the above-mentioned defects of the hookah inhalation device using an electric heating device, the inventor proposed a heating device in the Chinese utility model patent with application number 202321505038.5, including a hollow heating seat body and an electric heating element. The heating seat body is placed on the smoke pot of the hookah device, and the heating element is arranged in the heating seat body in non-direct contact. Ventilation holes are distributed on the bottom surface of the heating seat body, through holes are provided on the top surface, and multiple side air inlet holes are distributed along the circumference of the side wall.

[0005] When using the hookah inhalation device of the above scheme of the inventor, since the electric heating element and the tobacco paste in the tobacco pot are separated only by the bottom plate of the heating seat, the distance between the electric heating element and the tobacco paste is relatively close. Under the condition that the airflow reaching the tobacco paste position through the air vent is ensured to reach the operating temperature range of about 200-290°C, the temperature of the electric heating element will be much higher than the above operating temperature range, so the problem of spicy taste caused by the tobacco paste being burnt will still occur. Summary of the invention

[0006] In order to solve the technical problem that the airflow of the heating device of the hookah inhalation device in the prior art is unstable and the temperature is difficult to control, thus burning the tobacco paste, the present invention provides a heating device of the hookah inhalation device, comprising a shell, a bottom plate, a partition and an electric heating element, wherein:

[0007] The shell is hollow;

[0017] In one embodiment, the air flow inlet or the air flow outlet arranged on the peripheral area is an arc-shaped through hole.

[0018] In one embodiment, the electric heating element is disposed in the shell, and the electric heating element is a ring-shaped heating tube, which is placed flat above the partition.

At the same time, the gas compartment can also play a role in cooling and stabilizing the airflow, making the airflow smooth and stable. BRIEF DESCRIPTION OF THE DRAWINGS

The bottom plate 2, the partition 3 and the shell side wall between the bottom plate 2 and the partition 3 together enclose a gas compartment 5. The bottom plate 2 has an airflow outlet 21, and the partition 3 has an airflow inlet 31. The airflow inlet 31 and the airflow outlet 21 are staggered as a whole, that is, the airflow inlet 31 and the airflow outlet 21 do not have any overlapping area in the longitudinal direction. Preferably, the projection distance between the airflow inlet 31 and the airflow outlet 21 on the horizontal projection plane is greater than or equal to 1 / 4 or 1 / 5 of the maximum radial dimension of the shell 1.

[0035] In this embodiment, in order to facilitate installation and disassembly, the bottom plate 2 is screwed to the bottom of the housing 1 by means of threads. An annular boss 11 is formed on the middle side wall of the housing 1, and the partition plate 3 is placed on the annular boss 11. Figure 2 shown.

[0036] In this embodiment, the air inlet 31 is arranged at the center of the partition 3 and is a circular hole. The air outlet 21 is a plurality of ( Figure 2 There are three of them), which are arc-shaped through holes, and are preferably evenly arranged on the peripheral area of ​​the bottom plate 2.

[0037] Those skilled in the art can understand that the arrangement of the above-mentioned air flow inlet 31 and the outlet 21 is only a preferred embodiment of the present invention, and there are many alternatives to choose from. For example, alternatively, there are multiple air flow inlets 31, which are evenly arranged in a ring shape around the center of the partition 3, and there are multiple air flow outlets 21, which are evenly arranged on the peripheral area of ​​the bottom plate 2. Alternatively, there are multiple air flow inlets 31, and the air flow inlets 31 are evenly arranged on the peripheral area of ​​the partition 3, and the air flow outlet 21 is arranged at the center of the bottom plate 2. Alternatively, there are multiple air flow inlets 31, and the air flow inlets 31 are evenly arranged on the peripheral area of ​​the partition 3, and there are multiple air flow outlets 21, which are evenly arranged in a ring shape around the center of the bottom plate 2.

[0038] The electric heating element 4 is separated from the partition 3 and is arranged above the partition 3. Figure 3 , Figure 4 As shown. Preferably, the electric heating element 4 is staggered with the air flow inlet 31 of the partition 3. In the present embodiment, the electric heating element 4 is arranged in the shell 1, and the electric heating element 4 is an annular heating tube, which is placed flat above the partition 3.
