Description

Technical Field

[0001] This application relates to the field of hookah technology, and in particular to a built-in 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 Figure 1-4 This application illustrates a built-in temperature-sensing and heating device for electronic hookahs provided in an embodiment of the present application, comprising: a temperature-sensing component 1, a heating layer 2, and a heat-conducting substrate layer 3; The temperature sensing component 1 and the heating layer 2 are disposed on the same side of the thermally conductive substrate layer 3; The temperature sensing component 1 is disposed inside the hollow structure in the middle of 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 embedding a temperature-sensing component within the heating device of the electronic hookah. Specifically, a built-in temperature-sensing heating device for electronic hookahs includes: a temperature-sensing component 1, a heating layer 2, and a thermally conductive substrate layer 3; the temperature-sensing component 1 and the heating layer 2 are disposed on the same side of the thermally conductive substrate layer 3; the temperature-sensing component 1 is disposed inside the hollow structure in the middle of the heating layer 2. By embedding the temperature-sensing component 1, this application makes the temperature sensed by the temperature-sensing component 1 closer to the actual temperature of the heating element, thereby improving the accuracy of temperature detection.

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

[0024] It should be noted that the temperature sensing component 1 and the heating layer 2 are disposed on the same side of the thermally conductive substrate layer 3, so that the temperature sensing component 1 can be as close as possible to the heating layer 2. The temperature sensing component 1 is disposed inside the hollow structure in the middle of the heating layer 2, so that the heating layer 2 can be evenly surrounded by the temperature sensing component 1, thereby allowing the heat generated by the heating layer 2 to be fully conducted to the temperature sensing component 1.

[0025] As an example, the heat generated by the heating layer 2 is conducted to the heat-conducting substrate layer 3, and then the temperature sensing component 1 senses the temperature of the heat-conducting substrate layer 3 to achieve temperature detection.

[0026] 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 temperature sensing component 1 is disposed inside the hollow structure in the middle of the annular heating element 21; The annular heating element 21 is printed on the thermally conductive substrate layer 3.

[0027] It should be noted that the power supply pin 22 provides electrical energy to the annular heating element 21 for heating, and the power supply pin 22 can be sourced from the power supply component within the electronic hookah. The temperature sensing component 1 is disposed inside the hollow structure in the middle of the annular heating element 21, allowing the heat generated by the annular heating element 21 to be fully conducted to the temperature sensing component 1. The annular heating element 21 is printed on the thermally conductive substrate layer 3.

[0028] In one embodiment of this application, the heating layer 2 further includes a first electrode layer 23; the annular heating element 21 includes a plurality of elements. The first electrode layer 23 is printed on the thermally conductive substrate layer 3; The first electrode layer 23 is electrically connected to the plurality of annular heating elements 21, so that the first electrode layer 23, the power supply pin 22 and the plurality of annular heating elements 21 form a closed loop.

[0029] It should be noted that the multiple annular heating elements 21 are connected through the first electrode layer 23, and only one pair of power supply pins 22 is needed to achieve overall heating of the multiple annular heating elements 21. The multiple annular heating elements 21 can all surround the temperature sensing component 1. The multiple annular heating elements 21 can be distributed in concentric circles of different radii.

[0030] In one embodiment of this application, the temperature sensing component 1 includes a temperature sensing sheet 11 and a signal transmission pin 12 electrically connected thereto; The temperature sensing element 11 is printed on the thermally conductive substrate layer 3.

[0031] It should be noted that the temperature sensing element 11 can be a thin sheet structure. Printing the temperature sensing element 11 onto the thermally conductive substrate layer 3 allows the heat from the thermally conductive substrate layer 3 to be fully conducted to the temperature sensing element 11, thereby improving the accuracy of temperature detection.

[0032] In one embodiment of this application, the temperature sensing component 1 further includes a second electrode layer 13; the second electrode layer 13 is printed on the temperature sensing sheet 11; The temperature sensing element 11 is electrically connected to the signal transmission pin 12 through the second electrode layer 13.

[0033] It should be noted that the signal transmission pin 12 can be electrically connected to the main control board inside the electronic hookah, thereby transmitting the temperature sensing signal corresponding to the temperature sensing element 11 to the main control board and outputting the corresponding temperature value signal to the display screen of the electronic hookah for display; the power supply of the signal transmission pin 12 can come from the power supply component inside the electronic hookah.

[0034] In one embodiment of this application, it further includes: a first insulating layer 4; The temperature sensing component 1 and the heating layer 2 are disposed between the first insulating layer 4 and the thermally conductive substrate layer 3.

[0035] It should be noted that the first insulating layer 4 can cover the temperature sensing component 1 and the heating layer 2 disposed on the heat-conducting substrate to prevent the energized temperature sensing component 1 and the heating layer 2 from short-circuiting, thereby affecting the heating or temperature detection.

[0036] In one embodiment of this application, the first insulating layer 4 is printed on the thermally conductive substrate layer 3, the temperature sensing component 1, and the heating layer 2.

[0037] It should be noted that the structure of the first insulating layer 4 printed on the thermally conductive substrate layer 3 can separate the temperature sensing component 1 and the heating layer 2, preventing them from being electrically connected and thus causing circuit damage.

[0038] In one embodiment of this application, the thermally conductive substrate layer 3 includes a thermally conductive substrate 31, a second insulating layer 32, 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 temperature sensing component 1 and the heating layer 2 are disposed on the side of the second insulating layer 32 away from the heat-conducting substrate 31.

[0039] 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.

[0040] In one embodiment of this application, the second insulating layer 32 and the third insulating layer 33 are printed on the thermally conductive substrate 31; the heating layer 2 is printed on the second insulating layer 32.

[0041] It should be noted that the heating layer 2 can be a thin sheet structure. Printing the heating layer 2 on the second insulating layer 32 can ensure that the heat generated by the heating layer 2 can be fully conducted to the thermally conductive substrate 31.

[0042] In one specific embodiment of this application, the thermally conductive substrate layer 3 may be a porous structure.

[0043] It should be noted that, compared to solid structures, porous thermal conductive substrates have lower thermal inertia and larger heat dissipation area, resulting in faster temperature rise / fall and making them more suitable for applications requiring rapid temperature control. They also have multiple heat conduction paths, which makes the temperature distribution more uniform, less prone to heat accumulation, and less likely to cause stress damage. Furthermore, the porous structure can reserve space for thermal deformation, making it less prone to warping and thus improving service life.

[0044] In one specific embodiment of this application, 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 first insulating layer 4 may be provided with wiring holes corresponding to the signal transmission pin 12 and the power supply pin 22.

[0045] In one specific implementation, assembling the device may include the following steps: The second insulating layer 32 is printed on the thermally conductive substrate 31 and then baked at high temperature. A plurality of the annular heating elements 21 are printed on the second insulating layer 32 and then baked at high temperature. The temperature sensing element 11 is printed on the second insulating layer 32 and then baked at high temperature. The first electrode layer 23 is printed on the plurality of annular heating elements 21 respectively, and the second electrode layer 13 is printed on the temperature sensing element 11, and then baked at high temperature; The first insulating layer 4 is printed on the annular heating element 21, the temperature sensing element 11 and the second insulating layer 32 and then baked at high temperature. The third insulating layer 33 is printed on the thermally conductive substrate 31 and then baked at high temperature. The power supply pin 22 is spot-soldered on the first electrode layer 23, and the signal transmission pin 12 is spot-soldered on the second electrode layer 13.

[0046] 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.

[0047] 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.

[0048] Reference Figure 5-6 This application illustrates an electronic hookah provided in an embodiment of the present application, comprising: an atomizing pot 52 for containing tobacco, and a built-in 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.

[0049] 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.

[0050] 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.

Therefore, the appended claims are intended to be interpreted as including the preferred embodiments as well as all changes and modifications falling within the scope of the embodiments of the present application.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or terminal device that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or terminal device.
