Description

Technical Field

[0001] This application relates to the field of hookah technology, and in particular to an external temperature-sensing heating device for electronic hookahs. Background Technology

[0002] Arabian hookah originated in India and is mainly popular in Arab countries, with similar forms also existing in Turkey, Iran, and Central Asia. Traditional hookah devices typically hold tobacco at the top and water at the bottom. To use, burning charcoal is placed above the tobacco; the heat from the charcoal vaporizes the tobacco, forming smoke. This smoke is then filtered through the water layer at the bottom and inhaled through the pipe.

[0003] Currently, electronic hookahs that simulate the inhalation experience of traditional hookahs have appeared on the market. Their working principle is to use an electric current to heat the tobacco material (usually tobacco paste or e-liquid), atomizing it into a nicotine-containing aerosol for users to inhale.

[0004] However, existing electronic hookahs typically heat the device at a preset power level, making it impossible to monitor the temperature of the heating element in real time during the atomization process. Utility Model Content

[0019] To make the objectives, features, and advantages of this application more apparent and understandable, the application will be further described in detail below with reference to the accompanying drawings and specific embodiments. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0020] The inventors discovered through analysis of existing technologies that existing electronic hookahs typically heat at a preset power, and the heating temperature is usually constant. However, for electronic hookahs with multiple heating powers / temperatures, the temperature of different atomization stages is precisely controlled. Therefore, the temperature detection of the heating element is particularly important.

[0021] Reference Figures 1-5 This application illustrates an embodiment of an external temperature-sensing and heating device for electronic hookahs, comprising: a temperature-sensing component 11, a first insulating layer 4, a heating layer 2, and a heat-conducting substrate layer 3; The heating layer 2 is disposed between the first insulating layer 4 and the thermally conductive substrate layer 3; The temperature sensing component 11 is disposed on the side of the first insulating layer 4 away from the heating layer 2.

[0022] In the embodiments of this application, addressing the issue that existing electronic hookahs typically heat at a preset power, making it impossible to monitor the temperature of the heating element in real time during atomization, this application provides a solution by incorporating an external temperature-sensing component 11 into the heating device of the electronic hookah. Specifically, an external temperature-sensing heating device for electronic hookahs includes: a temperature-sensing component 11, a first insulating layer 4, a heating layer 2, and a thermally conductive substrate layer 3; the heating layer 2 is disposed between the first insulating layer 4 and the thermally conductive substrate layer 3; the temperature-sensing component 11 is disposed on the side of the first insulating layer 4 away from the heating layer 2. This application, through the external temperature-sensing component 11, enables the temperature-sensing component 11 to collect the heating temperature of the electronic hookah in real time, ensuring precise temperature control of the electronic hookah.

[0023] The following will further describe an external temperature-sensing heating device for electronic hookahs in this exemplary embodiment.

[0024] It should be noted that the first insulating layer 4 provides electrical isolation between the temperature sensing component 11 and the heating layer 2, preventing short circuits between the energized temperature sensing component 11 and the heating layer 2, which could affect heating or temperature detection. The temperature sensing component 11 can be a platinum resistance thermometer as the temperature sensing element.

[0025] As an example, the heat generated by the heating layer 2 is conducted to the first insulating layer 4, and then the temperature sensing component 11 senses the temperature of the first insulating layer 4 to achieve temperature detection.

[0026] In one embodiment of this application, the thermally conductive substrate layer 3 includes a second insulating layer 32; the heating layer 2 is disposed between the first insulating layer 4 and the second insulating layer 32.

[0027] It should be noted that the second insulating layer 32 can electrically isolate the heating layer 2 and the thermally conductive substrate layer 3, preventing current leakage from occurring when the heating layer 2 and the thermally conductive substrate layer 3 are electrically connected, thereby preventing damage to the electronic hookah.

[0028] In one embodiment of this application, the thermally conductive substrate layer 3 includes a thermally conductive substrate 31 and a third insulating layer 33; the thermally conductive substrate 31 is disposed between the second insulating layer 32 and the third insulating layer 33; the first insulating layer 4, the second insulating layer 32, the thermally conductive substrate 31 and the third insulating layer 33 are each provided with a plurality of corresponding openings; The second insulating layer 32 and the third insulating layer 33 are printed on the thermally conductive substrate 31.

[0029] It should be noted that the thermally conductive substrate 31 can be made of stainless steel; the second insulating layer 32 and the third insulating layer 33 are respectively disposed on both sides of the thermally conductive substrate 31, so that the thermally conductive substrate 31 is not prone to current leakage, which could lead to damage to the electronic hookah.

[0030] In one specific embodiment of this application, the thermally conductive substrate layer 3 may be a porous structure.

[0031] It should be noted that, compared to a solid structure, the porous thermal conductive substrate layer 3 has lower thermal inertia and a larger heat dissipation area, resulting in faster temperature rise / fall, making it more suitable for applications requiring rapid temperature control. It also has multiple heat conduction paths, making the temperature distribution more uniform, less prone to heat accumulation, and less likely to cause stress damage. The porous structure can reserve space for thermal deformation, making it less prone to warping and thus improving service life.

[0032] In one embodiment of this application, the heating layer 2 includes an annular heating element 21 and a power supply pin 22 electrically connected thereto; The annular heating element 21 is printed on the thermally conductive substrate layer 3.

[0033] It should be noted that the annular heating element 21 can be a structure formed by a strip heating element filling a certain planar area, and the overall heating of the annular heating element 21 can be achieved by connecting a pair of power supply pins 22 to both ends of the strip heating element. The annular heating element 21 is printed as a thin sheet structure on the thermally conductive substrate layer 3, which allows the heat generated by the annular heating element 21 to be fully conducted to the thermally conductive substrate layer 3.

[0034] In one embodiment of this application, the first insulating layer 4 is printed on the annular heating element 21 and the thermally conductive substrate layer 3.

[0035] It should be noted that the structure of the first insulating layer 4 printed on the thermally conductive substrate layer 3 can separate the annular heating element 21 from the outside of the device, preventing current leakage from the energized heating layer 2, which could lead to damage to the electronic hookah.

[0036] In one specific embodiment of this application, the first insulating layer 4 may be provided with a wiring hole corresponding to the power supply pin 22.

[0037] Reference Figure 1 and Figures 4-5 In one embodiment of this application, a fixing cover 12 is also included; the fixing cover 12 is disposed on the side of the first insulating layer 4 away from the heating layer 2; the temperature sensing component 11 is movably disposed inside the fixing cover 12.

[0038] It should be noted that the fixing cover 12 can prevent the temperature sensing component 11 from falling off and facilitate the installation of the temperature sensing component 11.

[0039] In one embodiment of this application, the fixing cover 12 includes a first fitting part 121, a second fitting part 122, and a receiving part 123 adapted to the temperature sensing component 11; The first bonding portion 121 and the second bonding portion 122 are respectively disposed on both sides of the receiving portion 123; the first bonding portion 121 and the second bonding portion 122 are connected to the first insulating layer 4.

[0040] It should be noted that by placing the first fitting part 121 and the second fitting part 122 on both sides of the receiving part 123, the fixing cover 12 can fit more tightly to the first insulating layer 4, further preventing the temperature sensing component 11 from falling off.

[0041] In one embodiment of this application, the receiving portion 123 is provided with a limiting baffle 124 and an opening 125 adapted to the temperature sensing component 11; The limiting baffle 124 is disposed on the side opposite to the accommodating portion 123 and the opening portion 125.

[0042] It should be noted that the limiting baffle 124 can prevent the temperature sensing component 11 from being over-inserted during installation or from falling off from the opposite side of the opening 125 during use.

[0043] In one embodiment of this application, the receiving portion 123 is provided with an elastic abutment member 126; When the temperature sensing component 11 is disposed inside the fixed cover 12, the elastic abutment 126 undergoes elastic deformation and abuts against the temperature sensing component 11, so that the temperature sensing component 11 adheres to the first insulating layer 4.

[0044] It should be noted that the elastic abutment 126 can make the temperature sensing component 11 fit more tightly against the first insulating layer 4, thereby improving the efficiency of heat transfer and thus improving the accuracy of temperature detection.

[0045] In one specific embodiment of this application, it further includes: a steel sheet 13, which is inserted into the fixing cover 12 from the opening 125. The steel sheet 13 and the fixing cover 12 clamp the wire of the temperature sensing component 11, so that the temperature sensing component 11 is further fixed in the fixing cover 12 to prevent it from falling off.

[0046] In one specific embodiment of this application, the first insulating layer 4 may be provided with a wiring hole corresponding to the power supply pin 22.

[0047] In one specific implementation, assembling the device may include the following steps: The third insulating layer 33 is printed on the thermally conductive substrate 31 and then baked at high temperature. The second insulating layer 32 is printed on the thermally conductive substrate 31 and then baked at high temperature. The annular heating element 21 is printed on the second insulating layer 32 and then baked at high temperature. The first insulating layer 4 is printed on the annular heating element 21 and the second insulating layer 32 and then baked at high temperature. The fixing cover 12 is spray-welded onto the first insulating layer 4, and the power supply pin 22 is spot-welded onto the annular heating element 21. The temperature sensing component 11 is installed in the fixed cover 12.

[0048] It should be noted that the layered printing structure gives the device a flat overall shape and a small size, making it more suitable for installation in an electronic hookah with an independent power supply. The printing process in this embodiment can be screen printing, or other coating processes such as pad printing, spraying, dispensing, decal application, deposition, and 3D printing.

[0049] In one specific embodiment of this application, the thickness of the first insulating layer 4, the second insulating layer 32 and the third insulating layer 33 can be 10um-150um.

[0050] Reference Figures 6-7 This application illustrates an electronic hookah provided in an embodiment of the present application, comprising: an atomizing pot 52 for containing tobacco, and an external temperature-sensing heating device for electronic hookah as described in any embodiment of the present application; The thermally conductive substrate layer 3 is disposed correspondingly to the atomizing pot 52.

[0051] In one embodiment of this application, the electronic hookah may further include a main unit 5 and a container 6 connected thereto, the atomizing pot 52 and the device are disposed inside the main unit 5; the heat-conducting substrate layer 3 is attached to the inner side of the steel cover 51 of the main unit 5, and the steel cover 51 can serve as a support structure for the device; the atomizing pot 52 is detachably disposed inside the main unit 5; the container 6 is filled with edible filter liquid and is provided with an exhaust pipe 61 for inhalation.

[0052] In one specific implementation, the heat generated by the heating layer 2 heats the smoke material in the atomizing pot 52 through the heat-conducting substrate layer 3 and the steel cover 51. The smoke generated by the smoke material in the atomizing pot 52 enters the external container 6 through the bottom of the main unit 5. The user can inhale the smoke in the container 6 through the air outlet pipe 61 of the container 6.
