Description

Technical Field

[0001] This utility model relates to the field of electronic heating technology, and more specifically, to a heating device and an electronic hookah. Background Technology

[0002] Hookah is a device that atomizes tobacco products and filters the smoke through water or other liquids for inhalation. Tobacco products suitable for hookah are typically solid or semi-solid aerosol bases, such as tobacco paste, which generally have little to no fluidity. Currently, atomization of these aerosol bases is generally achieved by heating with charcoal.

[0003] Charcoal heating is problematic because the temperature is uncontrollable and cannot be maintained at a stable level. This can lead to issues such as burning due to excessively high temperatures or insufficient gas flow, resulting in poor taste. Additionally, incomplete combustion of charcoal during roasting can release harmful substances like carbon monoxide, polluting the smoke from the hookah. Furthermore, charcoal roasting requires frequent charcoal replacements, and falling ash contaminates the smoke, making the process cumbersome and inconvenient. Existing electronic heating methods suffer from low heating efficiency, uneven heating, and low safety protection levels, resulting in a poor user experience. Utility Model Content

Detailed Implementation

[0024] To make the above-mentioned objectives, features and advantages of this utility model more apparent and understandable, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0025] In the description of this utility model, it should be understood that the terms "upper" and "lower" indicate the orientation or positional relationship based on the orientation or positional relationship when the product is in normal use.

[0026] The terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature.

[0027] Example 1:

[0028] See Figures 1-3Embodiment 1 of this utility model provides a heating device, including: a housing 1, the housing 1 having an inner cavity 101, a heating unit 2 disposed within the inner cavity 101, the heating unit 2 dividing the inner cavity 101 into a first chamber 1011 and a second chamber 1012 that are in communication with each other, the first chamber 1011 containing smoke material, the heating unit 2 including an electric heating element 21, a first heat-conducting plate 22 and a second heat-conducting plate 23, the electric heating element 21, the first heat-conducting plate 22 and the second heat-conducting plate 23 being fixed together by bolts, glue, clips, etc.; the first heat-conducting plate 22 is disposed on the side of the electric heating element 21 near the first chamber 1011. The second heat-conducting plate 23 is disposed on the side of the electric heating body 21 near the second chamber 1012. The housing 1 is provided with a first through port 102 communicating with the first chamber 1011 and a second through port 103 communicating with the second chamber 1012. This utility model heats the inner cavity through the electric heating body. The heating temperature of the electric heating body is controllable, avoiding the problem of excessively low or high temperature. When in use, the heat of the electric heating body 21 is transferred to the first heat-conducting plate 22 and the second heat-conducting plate 23. The first heat-conducting plate and the second heat-conducting plate heat the first chamber and the second chamber respectively, thereby improving the heating efficiency and the effect of heating and volatilizing the smoke.

[0029] See Figure 2 and Figure 3 The first chamber 1011 is located below the second chamber 1012. The tobacco, specifically hookah tobacco, is placed on the inner bottom surface of the first chamber 1011. Heating the tobacco produces smoke. The second opening 103 is an air inlet connecting to the outside, and the first opening 102 is a smoke outlet. The first opening 102 is connected to a negative pressure channel 104. The negative pressure within the negative pressure channel 104 draws the smoke-laden gas from the first chamber 1011 out through the first opening 102. One end of the negative pressure channel 104 connects to the mouth of a person, allowing the smoke from the first chamber 1011 to be drawn out through the body. When the smoky gas in the first chamber 1011 is discharged, outside air enters the second chamber 1012 through the second conduit 103 and is heated for the first time in the second chamber 1012 by the second heat-conducting plate 23. Then, this part of the air enters the first chamber 1011 and is heated for the second time by the first heat-conducting plate 22. As an extension, if the smoke is non-human inhalation smoke or other non-human inhalation smoke, one end of the negative pressure channel 104 can be connected to a negative pressure generating device such as a negative pressure pump, and the negative pressure pump can carry the first chamber 1011 out.

[0030] See Figure 2An installation cavity 24 is formed between the first heat-conducting plate 22 and the second heat-conducting plate 23. The electric heating element 21 is placed in the installation cavity 24. The electric heating element 21 is disc-shaped, and the upper and lower heating surfaces of the disc-shaped electric heating element 21 are large, so that heat can be transferred to the second heat-conducting plate 23 through the larger upper surface and to the first heat-conducting plate 23 through the larger lower surface, thereby improving the heat conduction effect. The first heat-conducting plate 22 is provided with a lead hole 224 for leading out the wire of the electric heating element 21. An annular sealing plug can be set in the lead hole 224 to prevent smoke leakage. During installation, the wire passes through the sealing plug. The first heat-conducting plate 22 is made of ceramic, aluminum, iron or copper, and the second heat-conducting plate 23 is made of ceramic, aluminum, iron or copper to improve the heat conduction performance. It is worth noting that the ceramic used in this embodiment is a type of ceramic with a high thermal conductivity. The ceramic also has high strength, high hardness and low heat. The expansion coefficient and other properties ensure stable thermal conductivity. The first heat-conducting plate 22 and the second heat-conducting plate 23 can also be made of other materials with good thermal conductivity. A thermostat electrically connected to the electric heating element 21 is installed in the inner cavity 101. The thermostat is used to detect the temperature inside the inner cavity 101 and control the electric heating element 21 to turn on and off. The thermostat is a temperature sensor or temperature switch and can be installed by bolts, glue, clips, etc. When the temperature inside the inner cavity 101 reaches the preset value, the electric heating element 21 is turned off. When the temperature inside the inner cavity 101 is lower than the preset value, the electric heating element 21 is turned on to maintain the heating at the preset temperature and avoid the problem of excessively high or low heating temperature. The thermostat can be set on the inner wall of the inner cavity, the first heat-conducting plate 22, the second heat-conducting plate 23 or the electric heating element 21. The power supply wire of the thermostat is passed out through the lead hole 224.

[0031] See Figure 2 and Figure 3 A first heat-conducting plate 22 has a first heat-conducting rib 221 on the side near the first chamber 1011, and a second heat-conducting plate 23 has a second heat-conducting rib 231 on the side near the second chamber 1012. The first and second heat-conducting ribs 221 and 231 increase the area in contact with air, thus improving heat conduction. In this embodiment, the first and second heat-conducting ribs 221 and 231 are circular in shape, and multiple concentric first and second heat-conducting ribs 221 and 231 are arranged. The shape of the first heat-conducting rib 221 and the second heat-conducting rib 231 can also be set as cylindrical, hemispherical, square, convex, finned, irregular protrusion, etc.; the first heat-conducting plate 22 is provided with a connecting groove 223 for connecting the first chamber 1011 and the second chamber 1012. The shape of the connecting groove 223 can be set as circular, elliptical, polygonal, square, strip, etc. There are multiple connecting grooves 223, generally two or more, to ensure smooth air conduction.

[0032] See Figure 1 and Figure 2An electric heating element 3 is provided on the outer side wall and / or inner side wall of the shell 1. The electric heating element 3 is an electric heating plate or an electric heating wire, which further improves the heating efficiency of the air in the inner cavity. The shell 1 can be made of a material with good thermal conductivity, such as metal. A shroud 105 is provided on the shell 1 in a ring. The second passage 103 is opened inside the shroud 105. When the human body stops inhaling, that is, when no negative pressure is generated in the negative pressure channel 104, the hot air in the second chamber 1012 will rise and gather inside the shroud 105 through the second passage 103, avoiding the loss of this part of hot air and causing waste. When the human body resumes inhaling, the hot air inside the shroud 105 can re-enter the second chamber 1012 through the second passage 103, improving the energy utilization rate and saving heat energy.

[0033] Example 2:

[0034] See Figure 4 and Figure 5 The difference between this embodiment 2 and embodiment 1 is that: a first ventilation notch 222 is provided on the first heat-conducting rib 221, and a second ventilation notch 232 is provided on the second heat-conducting rib 231, so that air can flow laterally on the heating surface of the two heat-conducting plates for heat exchange, and avoid the heating efficiency being affected by the obstruction of the lateral airflow; two heating units 2 are provided in the vertical direction to improve the heating efficiency. Of course, three or more heating units 2 can also be provided as needed, which will not be listed here.

[0035] Example 3:

[0036] See Figure 6 The difference between this third embodiment and the first embodiment is that the first heat-conducting rib 221 and the second heat-conducting rib 231 are cylindrical in shape, which has a simple structure and low production cost.

[0037] The heating device of this utility model heats the inner cavity through an electric heating element. The heating temperature of the electric heating element is controllable, avoiding problems of excessively low or high temperatures. The first and second heat-conducting plates heat the first and second chambers respectively, thereby improving heating efficiency. The first heat-conducting plate 22 is provided with a first heat-conducting rib 221 on the side near the first chamber 1011, and the second heat-conducting plate 23 is provided with a second heat-conducting rib 231 on the side near the second chamber 1012. The first and second heat-conducting ribs 221 and 231 increase the contact area with air, thereby improving the heat conduction effect.

[0038] Additionally, see Figure 7 and Figure 8This utility model also provides an electronic hookah, including the heating device described above. The electronic hookah also includes a hollow base 10, with the heating device placed inside the base 10. The base 10 is provided with a first opening 1001 communicating with a first through port 102 and a second opening 1002 communicating with a second through port 103. When in use, the human body inhales the smoke, and the outside air is discharged sequentially through the second opening 1002, the second through port 103, the second chamber, the first chamber, the first through port 102, and the first opening 1001. This electronic hookah also has the beneficial effects of the heating device described above, which will not be elaborated here.

[0039] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
