[0025] The present invention will now be described in detail with reference to the accompanying drawings.

[0026] like Figures 1 to 4 As shown, the present invention discloses an electronic hookah heating device with a cooling structure, comprising a heater 1 and a battery control unit 2, wherein the heater 1 and the battery control unit 2 are electrically connected; specifically, the electric heater 1 and the battery control unit 2 can be electrically connected via a wire or conductive pin. The battery control unit 2 provides power to the heater 1 and controls the operating state of the heater 1, ensuring stable operation of the heater 1, providing the necessary energy support for heating the smoking material, and ensuring the normal operation of the electronic hookah.

[0027] Heater 1 is used to heat the smoking material placed in the tobacco bowl to produce smoke; it uses electrical energy to convert into heat energy to heat the smoking material in the tobacco bowl so that it volatilizes and produces smoke; thus realizing the function of electronic hookah producing smoke that can be inhaled.

[0028] The heater 1 is equipped with an exhaust pipe 3 connected to the water filter pitcher. The exhaust pipe 3 is used to discharge flue gas. The exhaust pipe 3 establishes an exhaust channel for flue gas from the heater 1 to the water filter pitcher. This facilitates guiding the flue gas generated by heating to the water filter pitcher for further treatment and optimizes the flue gas quality.

[0029] A first gap 4 is provided between the heater 1 and the battery control unit 2, exposing the air pipe 3; the first gap 4 separates the heater 1 and the battery control unit 2, preventing heat from the heater 1 from being conducted to the battery control unit 2. At the same time, it can reduce the temperature of the upper surface of the battery control unit 2 and the lower surface of the heater 1.

[0030] The exhaust pipe 3 is provided with a through hole 31 that communicates with the first gap 4. The through hole 31 is used to adjust the temperature inside the exhaust pipe 3. The through hole 31 communicates with the first gap 4, allowing outside air to enter the exhaust pipe 3 through the through hole 31 and exchange heat with the high-temperature smoke inside. Lowering the temperature of the smoke inside the exhaust pipe 3 can reduce heat transfer from the exhaust pipe 3 to the battery control unit 2; on the other hand, it can avoid the burning sensation caused by directly inhaling the high-temperature smoke, thus improving the comfort of inhalation.

[0031] When the e-hair pipe is in operation, the battery control unit 2 supplies power to the heater 1, which heats the inhalation material to produce smoke. The smoke is discharged through the outlet pipe 3, which is connected to the heater 1 and leads to the water filter. Because there is a first gap 4 between the heater 1 and the battery control unit 2 that exposes the outlet pipe 3, and the outlet pipe 3 has a through hole 31 communicating with the first gap 4, external air can enter the interior of the outlet pipe 3 through the through hole 31. During the outflow process, the high-temperature smoke exchanges heat with the incoming external air, thus lowering the internal temperature of the outlet pipe 3. This reduces heat transfer from the outlet pipe 3 to the battery control unit 2 and prevents the user from directly inhaling the high-temperature smoke, thus improving the user's comfort when using the e-hair pipe. Finally, the smoke enters the water filter for further processing.

[0032] like Figure 2 and Figure 3 As shown, in this embodiment, a heat insulation ring 5 is provided on the outside of the heater 1, and a second gap 6 is provided between the heat insulation ring 5 and the outside of the heater 1 to allow air to pass through. The heat insulation ring 5 can block some of the heat from the heater 1 from being transferred outward, reducing the impact of heating on the surrounding area. This prevents the human body from accidentally touching the heater 1 and causing burns.

[0033] The second gap 6 allows air circulation to directly cool the heat insulation ring 5, making it convenient for users to remove the heater 1 at any time.

[0034] like Figure 2 and Figure 3 As shown, the heater 1 in this embodiment is provided with a limiting slot 11 and a limiting structure 12; by setting a specific slot and structure, a positioning and fixing foundation is provided for the installation of the heat insulation ring 5; ensuring the accuracy of the installation position of the heat insulation ring 5 and providing a guarantee for subsequent stable installation.

[0035] The heat insulation ring 5 is provided with a mounting edge 51, which abuts against the limiting groove 11. The heat insulation ring 5 is also threadedly connected to the limiting structure 12 via bolts. The contact between the mounting edge 51 and the limiting groove 11 achieves initial positioning, allowing the heat insulation ring 5 to be quickly and accurately positioned during installation and preventing misalignment. The threaded connection of the bolts securely fixes the heat insulation ring 5 to the limiting structure 12, further enhancing the stability of the heat insulation ring 5 installation, preventing loosening during use, and ensuring the continuous and effective heat insulation function of the heat insulation ring 5.

[0036] like Figure 3 As shown, the limiting structure 12 in this embodiment includes an upper limiting member 121 and a lower limiting member 122; The upper limit positioner 121 is set on the top of the heater 1, so that the upper limit positioner 121 is connected to the heater 1.

[0037] The lower limit member 122 is disposed at the top of the battery control unit 2. The lower limit member 122 is connected to the battery control unit 2.

[0038] The heat insulation ring 5 includes an upper heat insulation component 52 and a lower heat insulation component 53. The upper heat insulation component 52 is connected to the upper limit position component 121 by bolts, so that the upper heat insulation component 52 and the upper limit position component 121 are connected.

[0039] The lower heat insulation component 53 is connected to the lower limit component 122 by bolts, so that the lower heat insulation component 53 and the lower limit component 122 are connected to achieve heat insulation of the outer periphery of the heater 1.

[0040] like Figure 3 As shown, the top of the upper limit member 121 in this embodiment is provided with a heat insulation sheet 123; the heat insulation sheet 123 prevents excessive heat dissipation upwards and reduces the impact of high temperature on the upper part.

[0041] The first gap 4 is radially arranged along the lower limit member 122. This gap 4 accelerates heat dissipation between the heater 1 and the battery control unit 2, effectively reducing the temperature around the heater 1 and the exhaust pipe 3, preventing the user from experiencing a burning sensation due to high-temperature smoke, and improving smoking comfort. Simultaneously, it further protects the battery control unit 2, reducing the impact of the exhaust pipe 3's temperature on it.

[0042] like Figure 2 As shown, the air outlet pipe 3 in this embodiment includes an upper connecting part 32 and a limiting part 33.

[0043] The vent pipe 3 passes through the battery control unit 2, thus placing the vent pipe 3 inside the battery control unit 2. This makes efficient use of the internal space of the battery control unit 2 and rationally plans the route of the vent pipe 3, saving space. At the same time, the battery control unit 2 provides a certain degree of protection for the vent pipe 3.

[0044] The upper connecting part 32 is connected to the heater 1 to realize the transmission of flue gas from the heater 1 to the exhaust pipe 3; ensuring smooth exhaust of flue gas and fulfilling the basic function of electronic hookah generating and exhausting flue gas. Specifically, the upper connecting part 32 and the heater 1 can be an interference fit connection or a threaded connection.

[0045] The limiting part 33 abuts against the lower limiting part 122, and the abutting action is used to position and fix the air outlet pipe 3; to prevent the air outlet pipe 3 from shaking or shifting during use, to ensure the stable operation of the air outlet pipe 3, and to avoid damage to the pipe or affecting the inhalation effect due to position changes.

[0046] like Figure 2As shown, in this embodiment, the lower part of the exhaust pipe 3 is provided with a connecting plug 7 that connects to the water filter. The connecting plug 7 serves as a connecting component between the exhaust pipe 3 and the water filter, ensuring a tight fit between the exhaust pipe 3 and the water filter. This ensures that the exhaust pipe 3 can be securely and sealed to the water filter, allowing the smoke to enter the water filter smoothly and without leakage for subsequent processing. It prevents smoke leakage due to loose connection, avoids potential safety hazards caused by high-temperature smoke leakage, and also ensures the smoothness of the smoking process.

[0047] like Figure 4 As shown, the connecting plug 7 in this embodiment includes a connecting shell 71 and a smoke guide 72. By dividing the connecting plug 7 into two parts, the connecting shell 71 and the smoke guide 72, the structure of the connecting plug 7 becomes more flexible, better adaptable to different components, and improves the stability and reliability of the connection.

[0048] The connecting shell 71 is connected to the lower part of the exhaust pipe 3, so that the connecting shell 71 and the lower part of the exhaust pipe 3 fit tightly together; this ensures that the exhaust pipe 3 and the connecting plug 7 are firmly connected, allowing the flue gas to smoothly enter the interior of the connecting plug 7 from the exhaust pipe 3. The connection between the connecting shell 71 and the lower part of the exhaust pipe 3 can be an interference fit or a threaded connection.

[0049] The smoke guide 72 is fixed inside the connecting shell 71 and is used to guide the smoke into the hookah bottle. The smoke guide 72 is fixed in position within the connecting shell 71, forming a stable structure together with the connecting shell 71, ensuring that the smoke entering the connecting plug 7 can smoothly enter the hookah bottle.

[0050] An oil storage tank 73 for storing e-liquid is provided between the connecting shell 71 and the smoke guide 72. The oil storage tank 73 is formed by utilizing the space between the connecting shell 71 and the smoke guide 72; it can collect the condensed e-liquid that may be generated during the smoke transmission process, prevent the e-liquid from entering the water filter and affecting the normal operation of the water filter, and at the same time facilitate the cleaning of e-liquid, thus improving the user experience of the e-cigarette.

[0051] like Figure 4 As shown, in this embodiment, the inner diameter of the end of the smoke guide 72 near the exhaust pipe 3 is smaller than the inner diameter of the exhaust pipe 3. This difference in inner diameter creates a throttling structure. When smoke flows from the exhaust pipe 3 (with a larger inner diameter) into the port of the smoke guide 72 (with a smaller inner diameter), the smoke flow rate increases. This allows the smoke to concentrate more effectively when entering the connecting plug 7, reducing dispersion and turbulence at the connection point, ensuring smooth entry of the smoke into subsequent structures, and avoiding increased suction resistance due to poor smoke flow. Simultaneously, condensed e-liquid smoothly enters the oil storage tank 73 along the outer wall of the smoke guide 72.

[0052] like Figure 4As shown, the connecting shell 71 of this embodiment is provided with a pressure block 74 and a stop block 75 inside; by setting a special pressure block 74 and a stop block 75 structure inside the connecting shell 71, a fixing mechanism for the smoke guide 72 is constructed; providing a stable fixing effect for the smoke guide 72, ensuring that the position of the smoke guide 72 inside the connecting shell 71 is stable, preventing it from shaking or displacing during use, and ensuring the reliability of the overall structure of the connecting plug 7.

[0053] The lower part of the smoke guide 72 is provided with an extension 721, which provides a working part for the pressure block 74 and the abutment block 75, thereby expanding the contact range between the smoke guide 72 and the fixed structure inside the connecting shell 71.

[0054] The pressure block 74 presses against the edge of the extension 721, and the abutment block 75 abuts against the extension 721 and is connected to the pressure block 74. The pressure block 74 applies pressure to the edge of the extension 721, generating friction and restraint through surface-to-surface contact. The abutment block 75 abuts against the extension 721 from the other side, creating a clamping effect with the pressure block 74. Simultaneously, the connection between the abutment block 75 and the pressure block 74 enhances the overall fixing strength, ensuring that the smoke guide 72 will not loosen within the connecting shell 71.

[0055] The connection between the abutment block 75 and the pressure block 74 can be a threaded connection or an interference fit connection.

[0056] like Figure 3 As shown, the heater 1 in this embodiment includes a heating head 13 for heating the inhalation material to generate smoke and a heating pot 14 for placing the tobacco bowl, so that the heater 1 heats the inhalation material placed in the tobacco bowl to generate smoke.

[0057] The heating head 13 is covered on the top of the heating pot 14, so that the heating head 13 and the heating pot 14 are combined to form a complete heating system, providing a stable smoke generation environment for electronic hookahs and ensuring the continuity and stability of smoke generation.

[0058] The heating head 13 is provided with a lower convex ring 15, and the heating pot 14 is provided with a heat insulation ring 16. The heat insulation ring 16 is provided with a mating groove 161, and the lower convex ring 15 abuts against the mating groove 161. This allows the lower convex ring 15 to be accurately embedded in the mating groove 161, achieving a tight connection between the heating head 13 and the heat insulation ring 16.

[0059] When the heating head 13 is placed on top of the heating pot 14, a tight connection is formed through the abutment between the lower convex ring 15 and the mating groove 161. This ensures a secure connection between the heating head 13 and the heat insulation ring 16, preventing the heating head 13 from shaking or shifting during use. Simultaneously, it prevents gas leakage from the connection point between the heating head 13 and the heating pot 14, ensuring stable heating of the inhaled material by the heating head 13 and improving the performance and reliability of the electronic hookah.

[0060] like Figure 3 As shown, in this embodiment, the heat insulation ring 16 is connected to the exhaust pipe 3, so that the exhaust pipe 3 is connected to the heating pot 14, thereby realizing the connection between the exhaust pipe 3 and the heating pot 14 and being used to discharge flue gas.

[0061] An oil collection chamber 162 is provided on the outer periphery of the connection between the heat insulation ring 16 and the air outlet pipe 3. The oil collection chamber 162 is formed by a recessed space on the outer periphery of the connection. When oil in the flue gas condenses during transmission, the oil collection chamber 162 provides a place to contain the condensed oil. This effectively collects the oil generated by flue gas condensation, preventing oil from flowing down the outer wall of the air outlet pipe 3 and avoiding oil contamination of other components of the electronic hookah. It also facilitates user cleaning of the accumulated oil, improving the hygiene and lifespan of the electronic hookah.

[0062] like Figure 3 As shown, the heating head 13 of this embodiment is provided with a heating channel 131 that draws in external air. Through the heating channel 131, external air can enter the interior of the heating head 13. This ensures a stable inflow of air, providing a continuous air source for the heating process, thereby stably generating smoke to meet the user's inhalation needs.

[0063] The heating head 13 is equipped with a heating element 132 for heating the air inside the heating channel 131. The heating element 132 heats the air flowing into the heating channel 131, thus heating the external air to a suitable temperature to heat the smoking material in the tobacco bowl and generate smoke. The heating element 132 can be a heating wire, an electromagnetic coil, a heating rod, or a heating plate.

[0064] The heat insulation ring 16 has a heating chamber 163 inside for placing the tobacco bowl, providing a dedicated space for the tobacco bowl. At the same time, the heat insulation ring 16 can reduce heat loss. It not only facilitates the placement of the tobacco bowl, but also ensures that the heat of the tobacco bowl is concentrated during the heating process, improves heating efficiency, allows the smoking material to be fully heated to produce smoke, and reduces the impact of heat on surrounding components.

[0065] A space 164 for removing the tobacco bowl is provided between the heat insulation ring 16 and the heating head 13. When the tobacco bowl is placed in the heating chamber 163, the upper edge of the tobacco bowl is higher than the top of the heat insulation ring 16. This provides sufficient operating space for the user to easily and quickly remove the tobacco bowl, improving convenience and user experience.

[0066] like Figure 2As shown, the battery control unit 2 in this embodiment includes a housing 21 and a battery 22. The battery control unit 2 is formed by combining the housing 21 and the battery 22. The housing 21 provides a mounting base and protective structure for the battery 22, and the battery 22 serves as an energy source to power the electronic hookah-related components. A complete battery 22 control unit is formed, which provides stable power support for the normal operation of the electronic hookah.

[0067] The housing 21 has an internal cavity 221 for accommodating the battery 22, and the cavity 221 has heat dissipation holes 222 that communicate with the outside. The cavity 221 provides a dedicated space for the battery 22, allowing the battery 22 to be stably installed inside the housing 21. This ensures that the battery 22 is in a fixed position, preventing it from shaking or shifting during use, improving the stability and reliability of the battery installation, and facilitating maintenance and replacement of the battery 22.

[0068] The heat dissipation hole 222 provides a channel for the heat generated by the battery 22 in the cavity 221 to dissipate to the outside; it can effectively reduce the temperature of the battery 22 when it is working, prevent the battery 22 from being damaged due to overheating, extend the service life of the battery 22, and at the same time ensure that the battery 22 works stably in a suitable temperature environment, thus ensuring the stable performance of the electronic hookah.

[0069] Battery 22 is electrically connected to heater 1. This electrical connection establishes a power transmission path between battery 22 and heater 1, enabling battery 22 to provide the electrical energy required for heater 1 to operate. This ensures a stable power supply to heater 1, allowing it to function properly and heat the inhaled material to generate smoke.

[0070] The above description is only a preferred embodiment of the present invention. For those skilled in the art, there will be changes in the specific implementation and application scope based on the ideas of the present invention. The content of this specification should not be construed as a limitation of the present invention.
