Description

Technical Field

[0001] This utility model relates to the field of hookah technology, specifically to a heating component for a hookah. Background Technology

[0002] Traditional hookahs are typically heated using charcoal, a method that is slow to heat up, wastes the user's time, and makes precise temperature control difficult. Excessive heat can cause the tobacco to burn, producing unpleasant flavors and harmful substances; insufficient heat results in inadequate smoke, affecting the smoking experience. Furthermore, heating hookahs with charcoal requires someone to constantly add new charcoal to the bowl, a cumbersome process. With the continuous development of electronic technology, electric heating technology has been applied to hookah devices.

[0003] A patent document with authorization announcement number CN219762458U discloses an electrically heated hookah, including a water tank and a body. The water tank is used to hold liquid, and the body is located above the water tank. The lower end of the body is detachably connected to the water tank. The upper end of the body is provided with a heating chamber, and the inner wall of the heating chamber is provided with an electric heating component. A heating cup is provided inside the heating chamber, and the heating cup is in contact with the heating component. This solution uses electric heating to heat the tobacco in the hookah, thereby solving the problems existing in traditional charcoal burning.

[0004] However, its electric heating element is a heating wire, which is wound around the outer wall of the heating cup. The heating wire is only wound around the outside of the heating cup, and there is a gap between the heating cup and the heating wire. This makes it impossible for the heating wire to heat the heating cup evenly. Some parts of the tobacco may be overheated, resulting in burning and producing unpleasant tastes such as burnt taste, which seriously affects the taste. Other parts may be underheated, failing to fully release the aroma and effective ingredients of the tobacco, resulting in less smoke and a weak taste, which cannot achieve the ideal smoking experience. In addition, the heating efficiency of the heating cup for tobacco is relatively slow, making it inconvenient to use. Summary of the Invention

[0005] The present invention aims to solve the technical problem in the prior art where the connection between the heating component and the heating cup is not tight enough, resulting in uneven heating of the heating cup and low heating efficiency.

[0006] To solve the above-mentioned technical problems, this utility model provides a heating assembly for a hookah, including a heating pot, which has an outer wall and an outer bottom wall. A side heating element is provided on the outer wall, and a retaining ring is provided on the side of the side heating element away from the outer wall to press the side heating element against the outer wall. Structural adhesive is filled between the heating pot and the retaining ring. After the structural adhesive cures, the heating pot, the side heating element and the retaining ring are tightly connected.

[0007] In the above structure, a side heating element is set on the outside of the heating pot, and then the side heating element is pressed tightly against the outer wall of the heating pot by a retaining ring. Structural adhesive is filled between the retaining ring and the heating pot. After the structural adhesive cures, the heating pot, the side heating element and the retaining ring are tightly connected. The heating element can heat the side wall of the heating pot evenly, which improves the heating efficiency. Attached Figure Description

[0015] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0016] like Figures 1 to 6 As shown, a heating component for a hookah is used to heat the bowl 100. When using the hookah, tobacco paste and other tobacco materials are added to the bowl 100.

[0017] The heating assembly includes a heating pot 1, which has an outer outer wall 11 and an outer bottom wall 12.

[0018] A side heating element 2 is provided on the outer wall 11. The side heating element 2 includes a bendable side heating sheet 21. In this embodiment, the side heating sheet 21 is made of stainless steel sheet by stamping or laser cutting. When manufacturing the side heating sheet 21, stamping is preferred because the shape of the side heating sheet 21 and the internal holes can be formed in one step during stamping. The side heating sheet 21 has polygonal holes with uniform spacing to increase the impedance. This technology is prior art, and its specific structure will not be described here.

[0019] In order to supply power to the side heating element 21, the existing technology usually welds wires to both ends of the side heating element 21. However, the connection is not strong when using simple welding. Therefore, in this embodiment, terminal blocks 22 are provided at both ends of the side heating element 21. The side heating element 21 and the terminal blocks 22 are connected by riveting. The wires are inserted into the terminal blocks 22 and clamped by pliers. In this way, the wires can be reliably connected to the side heating element 21. Furthermore, in order to improve conductivity, solder can be applied at the connection between the side heating element 21 and the terminal blocks 22.

[0020] The side heating element 21 can be bent so that it can fit tightly against the outer wall 11 of the heating pot 1. This can maximize the contact area between the side heating element 21 and the outer wall 11 of the heating pot 1, thereby improving the heat transfer efficiency and allowing the heat to be transferred more evenly to the heating pot 1. This avoids uneven heating and improves the heating effect and user experience of the hookah.

[0021] like Figure 2 and Figure 3 As shown, a retaining ring 3 is provided on the side of the side heating element 2 away from the outer wall 11 to press the side heating element 2 against the outer wall 11. Typically, the retaining ring 3 is an integral structure with an opening. The inner wall of the retaining ring 3 can fit tightly with the outer wall 11 of the heating pot 1. The opening is used to avoid the wiring terminal 22. However, since the thickness of the wiring terminal 22 is greater than that of the side heating element 2, there are two solutions for smooth assembly. First, the opening is designed as a through groove to completely avoid the wiring terminal 22. The advantage of this design is that during assembly, the side heating element 21 can be wrapped around the outer wall 11 of the heating pot 1 first, and then the retaining ring 3 can be pushed directly onto the outer wall 11 of the heating pot 1. The first option is to place the heating element on the outer wall 11. The disadvantage of this design is that the end of the side heating element 21 cannot be tightly secured by the retaining ring 3, meaning that the end of the retaining ring 3 cannot be tightly connected to the outer wall 11 of the heating pot 1, which will also result in uneven heating. The second option is to design the opening as a notch, that is, not as a through groove. This option requires first fastening the retaining ring 3 to the outer wall 11 of the heating pot 1, and then inserting the side heating element 21 between the retaining ring 3 and the outer wall 11 of the heating pot 1, so that the wiring terminal 22 is located at the notch. Since the heating element 21 is relatively soft, it is more difficult to perform this operation, and it cannot be guaranteed that the side heating element 21 can be accurately installed every time.

[0022] To address the shortcomings of the two designs mentioned above, this embodiment provides a better solution by splitting the retaining ring 3 into upper and lower parts. The retaining ring 3 includes an upper retaining ring 31 and a lower retaining ring 32. The upper retaining ring 31 has a clearance notch 311 to avoid the flange 14; the lower retaining ring 32 has an opening 321 to avoid the wiring terminal 22. During assembly, the side heating element 21 is first wrapped around the outer wall 11 of the heating pot 1, and then the upper retaining ring 31 is assembled, ensuring that the clearance notch 311 passes through the wiring terminal 22. After the upper retaining ring 31 is fully fastened onto the side heating element 21, rotate the upper retaining ring 31 so that the notch 311 is offset from the end of the terminal 22. In this way, the upper retaining ring 31 can press the two ends of the side heating element 21 tightly to prevent the side heating element 21 from tilting up. The upper retaining ring 31 can press the upper part of the side heating element 21 tightly onto the outer wall 11 of the heating pot 1. After installing the upper retaining ring 31, continue to install the lower retaining ring 32. After the opening 321 of the lower retaining ring 32 is away from the terminal 22, fasten it onto the side heating element 21.

[0023] By pressing the side heating element 21 tightly onto the outer wall 11 using the retaining ring 3, it is ensured that the side heating element 21 is in close contact with the outer wall 11 of the heating pot 1, which enhances the reliability of the contact between the side heating element 2 and the heating pot 1 and ensures the stability and uniformity of the heating effect.

[0024] like Figure 2 As shown, to ensure a tighter connection between the heating pot 1, the side heating element 21, and the retaining ring 3, and to expel air and prevent oxidation of the side heating element 21, structural adhesive is filled between the heating pot 1 and the retaining ring 3. After the structural adhesive cures, the heating pot 1, the side heating element 21, and the retaining ring 3 are tightly connected. The structural adhesive further enhances the connection between the heating pot 1, the side heating element 21, and the retaining ring 3, preventing the side heating element 21 from loosening or shifting during use. At the same time, the structural adhesive provides a good seal, preventing external dust, moisture, and other impurities from entering and causing corrosion or damage to components such as the side heating element 21 and the wiring terminal 22. This protects the normal operation of internal electrical components and improves the protective performance and durability of the heating assembly.

[0025] In this embodiment, ceramic adhesive is used as the structural adhesive. After the adhesive is applied, the ceramic adhesive is sintered and cured, so that the heating pot 1, the side heating element 2 and the retaining ring 3 are tightly connected.

[0026] A side insulation layer 7 is provided on the outside of the retaining ring 3; a bottom insulation layer 8 is provided on the outside of the outer bottom wall 12; the side insulation layer 7 and the bottom insulation layer 8 can effectively block heat from being transferred to the outside. This allows more heat to be concentrated in the heating pot 1 and its interior, improving heating efficiency.

[0027] In this embodiment, the side insulation layer 7 and the bottom insulation layer 8 are made of aerogel. Since aerogel is one of the solid materials with the lowest known thermal conductivity, it has extremely excellent heat insulation performance. The side insulation layer 7 and the bottom insulation layer 8 are made of aerogel, which minimizes heat loss and makes the heat more concentrated on the heating pot and the tobacco, improving heating efficiency and helping to maintain a stable heating temperature. At the same time, aerogel has good chemical stability and is not likely to react with the tobacco in the hookah or the substances generated during the heating process, ensuring the safety and reliability of the hookah.

[0028] like Figure 3 and Figure 6 As shown, a side edge 13 extending outward is provided at the top of the heating pot 1, and a flange 14 extending towards the bottom of the heating pot 1 is provided at the bottom of the side edge 13. The flange 14 and the outer wall 11 form a temperature control mounting cavity 15, and a temperature measuring probe 4 is provided in the temperature control mounting cavity 15. The temperature control mounting cavity 15 can protect the temperature measuring probe 4 from being damaged by external physical collisions, ensuring its normal operation and the accuracy of temperature measurement.

[0029] like Figure 1 , Figure 4 and Figure 5 As shown, the heating assembly also includes an upper shell 9 and a lower shell 10. The upper shell 9 is a hollow cylindrical structure. A retaining ring 91 extending inward is provided at the top of the upper shell 9 to block the heating pot 1. The retaining ring 91 is used to block the heating pot 1. A fixing ring 92 extending outward is provided in the middle of the upper shell 9 for fixing. The fixing ring 92 has two or more fixing holes 93. In this embodiment, there are three fixing holes 93. The heating assembly is fixed in the body of the hookah through the fixing ring 92 and the fixing holes 93 on the fixing ring 92.

[0030] The lower shell 10 is fitted onto the bottom of the upper shell 9. The lower shell 10 and the upper shell 9 can be connected by an interference fit. A connecting post 101 and a pipe joint 102 are provided at the bottom of the lower shell 10. The connecting post 101 is connected to the body of the hookah, and the lower end of the pipe joint 102 is connected to the liquid space inside the hookah. The upper end of the pipe joint 102 is connected to the heating pot 1.

[0031] In this embodiment, the heating pot 1, the retaining ring 3, and the pressure ring 6 are all made of ceramic. Ceramic materials are chemically stable and do not easily react with tobacco, substances generated during the heating process, or chemicals in the external environment. This avoids material corrosion, discoloration, or the generation of harmful substances due to chemical reactions, ensuring the safety and hygiene of the hookah. At the same time, ceramic is a poor conductor of heat and has good heat insulation properties. The retaining ring 3 and the pressure ring 6 are made of ceramic material, which can effectively block heat from being transferred outward, further enhancing the heat insulation effect, reducing heat loss, and improving energy utilization efficiency.

[0032] As a further improvement, to provide a faster heating rate, the present invention also provides another embodiment.

[0033] like Figure 5 and Figure 7 As shown, a bottom heating element 5 is provided on the outer bottom wall 12. The bottom heating element 5 includes a bottom heating plate 51. A pressure ring 6 is provided on the side of the bottom heating plate 51 away from the outer bottom wall 12. Structural adhesive is filled between the outer bottom wall 12 and the pressure ring 6. After the structural adhesive is cured, the heating pot 1, the bottom heating plate 51 and the pressure ring 6 are tightly connected.

[0034] The bottom heating element 51 heats the outer bottom wall 12 of the heating pot 1, and together with the side heating element 2, the heating pot 1 is heated, resulting in a faster heating speed. The pressure ring 6 presses the bottom heating element 51 tightly onto the outer bottom wall 12, ensuring that the bottom heating element 51 and the outer bottom wall 12 are in close contact. At the same time, structural adhesive is filled between the pressure ring 6 and the outer bottom wall 12, which further enhances the fixation of the bottom heating element 51 and prevents the bottom heating element 51 from oxidizing.
