Description

Technical Field

[0001] This utility model relates to the field of hookah technology, specifically to a replaceable electronic hookah host. Background Technology

[0002] Electronic hookahs typically consist of a container filled with liquid and a main unit connected to the container. They are generally divided into integrated and separate types. Among them, separate electronic hookahs are more popular with users because they have the following advantages: they are easy to carry after being detached; the main unit can be updated and iterated quickly, allowing users to actively replace it with a new generation; and the main unit can be quickly replaced when it is damaged.

[0003] Meanwhile, traditional hookahs typically use charcoal combustion to heat the tobacco, which makes the heat source difficult to control and results in low heating efficiency. Furthermore, the combustion of charcoal releases harmful substances such as carbon monoxide and soot, which are harmful to human health if inhaled for a long time. Additionally, some existing electronic hookah atomizers use heating wires or heating rods for heating, which are in direct contact with the atomizing medium and are prone to uneven heating. Localized high-temperature atomization may produce harmful substances, and the heat retention effect is poor.

[0004] Furthermore, traditional hookahs lack effective start-up and temperature control mechanisms. If constant temperature heating is used, the power consumption will be too fast; if the heating time is fixed, the tobacco is prone to overheating and burning, resulting in poor taste and affecting the smoking experience.

[0005] Therefore, it is necessary to design a new host to solve the problems existing in the current technology. Summary of the Invention

[0006] The present invention aims to solve the technical problems of inconvenient carrying of water pipes, unreasonable start-up mechanisms, uneven heating of the tobacco, and slow heating efficiency in the prior art.

[0007] To achieve the above objectives, the technical solution of this utility model is as follows: a replaceable electronic hookah host includes a housing, a heating component is provided in the upper part of the housing, a battery component is provided below the heating component, and the heating component is electrically connected to the battery component; a connector is provided in the lower part of the housing, and an air pipe is provided between the connector and the heating component; an air hole is provided on the side wall of the air pipe, an airflow switch is provided on the housing, and an air passage for triggering the airflow switch is also provided on the housing, the air hole communicating with the air passage; the heating component includes a heating pot, the heating pot having an outer wall and a bottom wall, and a heating element is provided on the outer wall and / or the bottom wall.

[0008] This design allows the main unit to be connected to the container via a connector. When traveling or needing to replace the main unit, it can be simply unplugged, saving space and allowing the original container to be used with the new main unit, thus reducing operating costs. A heating element is placed on the outside of the heating pot, ensuring even heating. The heating element almost completely surrounds the outside of the pot, resulting in a larger heating area and faster temperature rise. An airflow switch prevents the heating element from activating when not smoking. When smoking, airflow through the air passage triggers the airflow switch, opening it and activating the heating element to quickly bring the temperature back to the set point. This results in faster heating efficiency and allows the heating element to be turned on only when smoking, preventing prolonged heating of the tobacco paste and thus maintaining the flavor of the smoke while saving energy.

Detailed Implementation

[0010] The present invention will now be described in further detail with reference to the accompanying drawings and specific embodiments.

[0011] like Figures 1 to 5As shown, a replaceable electronic hookah host includes a housing 1, within which a heating assembly 2 and a battery assembly 3 are disposed, the heating assembly 2 being electrically connected to the battery assembly 3; the heating assembly 2 includes a heating pot 21, the heating pot 21 having an outer wall 211 and a bottom wall 212, and a heating element 213 being disposed on the outer wall 211 and / or the bottom wall 212. In this embodiment, the heating element 213 is disposed on the outer wall 211, the heating element 213 including a bendable side heating plate, with wiring terminals at both ends of the side heating plate, the side heating plate being connected to the wiring terminals by riveting; a retaining ring 214 is provided on the side of the heating element 213 away from the outer wall 211 to press the heating element 213 tightly onto the outer wall 211, structural adhesive is filled between the heating pot 21 and the retaining ring 214, after the structural adhesive cures, the heating pot 21, the heating element 213 and the retaining ring 214 are tightly connected; a hookah bowl 8 is disposed inside the heating pot 21.

[0012] The heating element 213 is mechanically pressed against the outer wall of the heating pot 21 by the retaining ring 214. Combined with the tight connection after the structural adhesive has cured, this minimizes thermal resistance and prevents heat loss due to gaps between components. This allows the heat from the heating element 213 to be transferred to the heating pot 21 more directly and quickly, improving heating efficiency. Furthermore, the heating pot 21 is evenly wrapped and tightly contacted by the heating element 213, allowing heat to diffuse evenly along the side wall of the heating pot 21. This ensures that the tobacco bowl 8 inside is heated evenly, preventing local overheating or underheating and ensuring stable heating of the tobacco and consistent taste. At the same time, the mechanical clamping force of the retaining ring 214 and the curing and fixing of the structural adhesive form a "double guarantee," resisting loosening caused by vibration and temperature changes during use. This prevents the heating element 213 from loosening from the heating pot 21, avoiding local overheating and component damage due to poor contact.

[0013] like Figures 4 to 6 As shown, a connector 4 is located at the bottom inside the housing 1, and an air pipe 5 is located between the connector 4 and the heating component 2. An air hole 51 is provided on the side wall of the air pipe 5. An airflow switch 6 is provided on the housing 1, and an air passage 10 is also provided on the housing 1 for triggering the airflow switch. The air hole 51 communicates with the air passage 10. When there is no smoking for a long time, the airflow switch 6 is not activated, and the temperature of the heating element 213 automatically returns to a safe temperature, effectively protecting the flavor of the tobacco paste. When smoking, the change in air pressure inside the housing will cause airflow to pass through the air passage 10, thereby triggering the airflow switch 6. The airflow switch 6 opens, and the heating element 213 starts heating, so that the temperature quickly returns to the set temperature. This makes the heating efficiency faster, and it can be turned on and off as needed, without worrying about the flavor of the smoke changing due to prolonged heating of the tobacco paste.

[0014] like Figures 1 to 4As shown, the housing 1 includes an outer shell 11 and an inner shell 12. The battery assembly 3 is disposed in the inner shell 12. A cover assembly 7 is provided on the top of the outer shell 11. The cover assembly 7 includes a top cover 72. A flip cover assembly 73 for covering the heating assembly 2 is hinged to the top cover 72. A switch 90 for locking the flip cover assembly 73 is provided on the side of the top cover 72. The user controls the flip cover assembly 73 to flip upward through the switch 90, and then adds tobacco to the tobacco bowl 8, or removes the tobacco bowl 8 from the heating pot 21 for cleaning.

[0015] A top pot sleeve 9 is fitted over the outer shell 22. The top pot sleeve 9 has an axial portion 91 and a radial portion 92 that are connected to each other. The edge of the radial portion 92 is engaged between the heating pot 21 and the smoke pot 8. An elastic member 20 is provided between the axial portion 91 and the upper shell 22 to lift the top pot sleeve 9. A flange 721 is provided on the top cover 72 to prevent the top pot sleeve 9 from falling off. After the flip cover assembly 73 is folded, the elastic member 20 lifts the top pot sleeve 9, and the edge of the radial portion 92 is located below the edge of the smoke pot 8. When the top pot sleeve 9 is lifted, the smoke pot 8 is also lifted, so that the horizontal height of the smoke pot 8 is higher than that of the top cover 72, making it convenient for the user to take out and put away the smoke pot 8.

[0016] The cover assembly 7 also includes a fixing member 71 with a receiving cavity, the heating component 2 is disposed in the fixing member 71, and the upper part of the fixing member 71 is fixedly connected to the top cover 72; in this embodiment, the fixing member 71 has a bottom wall with a through hole, the heating component 2 is engaged with the through hole, and a plurality of support columns 711 extend downward on the outer side of the bottom of the fixing member 71, through which the fixing member 71 is connected to the inner shell 12.

[0017] The support column 711 at the bottom of the fixing member 71 connects the fixing member 71 to the inner shell 12 in a gap, forming a gap between them. The electrical connection lines between the heating component 2 and the battery component 3 can pass through the gap, preventing the lines from being squeezed or tangled. At the same time, the heating component 2 and the battery component 3 are separated from the inner shell 12 by the gap, reducing heat accumulation caused by mutual heat conduction and preventing the heating component 2 from transferring heat to the battery component 3 when it is working. The fixing member 71 separates the heating component 2 from the battery component 3, preventing the heating component 2 from transferring heat to the battery component 3 through thermal radiation. At the same time, the gap can serve as an air circulation channel, helping heat to dissipate through the heat dissipation holes of the shell 1 and protecting the battery.

[0018] like Figure 4 , Figure 5 and Figure 9 As shown, the heating assembly 2 also includes an upper shell 22 and a lower shell 23. The upper shell 22 is a hollow cylindrical structure. The upper shell 22 is mainly responsible for accommodating and fixing the heating assembly 2. The upper shell 22 encloses the heating pot 21 and the heating element 213, which can reduce the direct transfer of heat to the outside. At the same time, it can isolate the high-temperature heating element from the external circuit and air passage.

[0019] A retaining ring 221 extending inward is provided on the top of the upper shell 22 to block the heating pot 21. The upper edge of the heating pot 21 extends outward to form a blocking edge. When the heating pot 21 is placed on the upper shell 22, the blocking edge abuts against the bottom of the retaining ring 221, so that the heating pot 21 will not detach from the top of the upper shell 22.

[0020] A fixing ring 222 extending outwards is provided in the middle of the upper housing 22 for fixing; the lower housing 23 is sleeved on the bottom of the upper housing 22, and a connecting post 231 and a pipe joint 232 are provided at the bottom of the lower housing 23. The upper part of the pipe joint 232 extends into the connecting post 231, the upper end of the air pipe 5 is inserted into the pipe joint 232, and the lower end of the air pipe 5 is inserted into the upper end of the connector 4; a connecting seat 233 corresponding to the connecting post 231 is formed inside the lower housing 23, and the connecting seat 233 and the connecting post 231 are connected. All 31 are hollow and interconnected. A vent 215 is provided at the bottom of the heating pot 21. The edge of the vent 215 extends downward to form a connecting part 216. The connecting part 216 is inserted into the connecting seat 233. The upper end of the pipe connector 232 is inserted into the connecting part 216, so that the gas pipe 5 is connected to the interior of the heating pot 21. Multiple vent holes are provided at the bottom of the smoke pot 8, so that the inner cavity of the smoke pot 8 is connected to the inner cavity of the heating pot 21, thereby connecting the gas pipe 5 to the inner cavity of the smoke pot 8.

[0021] The lower part of the upper housing 22 and the lower housing 23 pass through the through hole and are located on the outside of the bottom wall of the fixing member 71; the fixing ring 222 of the upper housing 22 is limited to the through hole and is fixedly connected to the bottom wall of the fixing member 71; the battery assembly 3 is located below the lower housing 23, and a wire hole is opened at the bottom of the lower housing 23 to facilitate the electrical connection between the heating element 213 located in the upper housing 22 and the battery assembly 3 below.

[0022] like Figure 6 and Figure 7 As shown, the inner shell 12 has a downward-opening battery receiving cavity 121, and the battery assembly 3 is placed inside the battery receiving cavity 121. A through hole is provided at the top of the inner shell 12, and a hollow tube connecting post 122 extends from the edge of the through hole into the interior of the battery receiving cavity 121. An air pipe connecting sleeve 30 is provided at the top of the tube connecting post 122, and a connector 4 is provided below the tube connecting post 122. An air pipe 5 is placed in the tube connecting post 122, and the upper end of the air pipe 5 passes through the air pipe connecting sleeve 30 and is connected to the heating assembly 2. An airflow switch mounting seat 123 is provided at the top of the inner shell 12. The air passage 10 includes a groove extending along the inner side wall and bottom wall of the airflow switch mounting seat 123 to the inner side wall of the tube connecting post 122. The airflow switch 6 is installed in the airflow switch mounting seat 123, and the edge of the air pipe connecting sleeve 30 presses against the airflow switch 6.

[0023] like Figures 9 to 12As shown, in this embodiment, a container 100 containing liquid is connected to the bottom of the main unit. A hollow connecting component is provided on the top of the container 100, extending below the connector 4 to connect the air pipe 5 to the container 100. A sealing element is provided on the outside of the connecting component to ensure no air leakage at the connection between the connecting component and the connector 4. A hookah mouthpiece 101 is also provided on the container 100. When the user inhales through the hookah mouthpiece 101, a negative pressure is generated inside the container 100. Outside air passes through the heated tobacco bowl 8 and reacts chemically with the tobacco inside the bowl 8 to produce smoke. The smoke flows downwards... The air tube 5 enters the container 100 and is inhaled by the user after being filtered by the liquid. Since the side wall of the air tube 5 has an air hole 51, when the user inhales through the water pipe 101, some of the air in the pipe connecting column 122 flows into the air tube 5 through the air hole 51. The air passage 10 is connected to the pipe connecting column 122. After the air in the pipe connecting column 122 flows into the air tube 5, the outside air flows into the pipe connecting column 122 through the air passage 10. When the air flows through the air passage 10, the airflow switch 6 is activated, and the heating element 213 begins to heat the heating pot 21. No additional switching operation is required during the process, making it more convenient to use.

[0024] The battery assembly 3 includes a battery housing 31, on which a clearance hole 311 is provided for the tube connecting post 122 to be positioned. The edge of the clearance hole 311 extends into the battery housing 31 to form a clearance channel 312, in which the tube connecting post 122 is placed. Multiple batteries 32 are arranged around the clearance channel 312 inside the battery housing 1, making full use of space. This makes the overall main unit smaller and easier to carry and transport.

[0025] The inner shell 12 has a base 124 extending out of the outer shell 11. The outer shell 11 and the inner shell 12 are fixedly connected by the base 124. Locking members 40 are symmetrically arranged on the base 124. A locking groove 313 is provided at the bottom of the battery shell 31. The locking members 40 can be movably engaged into the locking groove 313, so that the battery assembly 3 is fixed in the battery receiving cavity 121. After the locking members 40 are unlocked, the battery assembly 3 can be removed from the battery receiving cavity 121 of the inner shell 12 as a whole. A charging interface is provided on the battery shell 11, which can charge the battery assembly 3 separately and replace it with a new battery assembly 3 without waiting for charging. It can still be used for a long time even outdoors. At the same time, a charging interface is also provided on the outer shell 11, so users can charge directly through the main unit without disassembling the battery assembly 3, which is convenient for daily use.

[0026] like Figure 4As shown, the flip-top assembly 73 includes a flip-top body 731, a fixing hole 70 is provided in the center of the flip-top body 731, a pressure cover 732 is provided at the fixing hole 70, and a fixing piece 733 is provided on the top of the flip-top body 731 to fix the pressure cover 732. The bottom of the pressure cover 732 extends downward to form a pressure cover flange 730. A tobacco bowl lid 80 is provided above the tobacco bowl 8. After the flip-top assembly 73 is closed, the pressure cover 732... The pressure flange 730 presses against the bowl lid 80, limiting the bowl lid 80 to be positioned above the bowl 8. Under the limitation of the pressure flange 730, the bowl lid 80 will not shift due to shaking of the main unit or smoking action, ensuring structural stability during use. Multiple through holes are provided on both the pressure flange 732 and the bowl lid 80, allowing outside air to enter the bowl 8. A switch 90 for locking the flip-top assembly 73 is provided on the side of the top cover 72.

[0027] The hookah host of this solution connects to the container 100 via a connector. When going out or needing to replace the host, the host can be directly unplugged, saving carrying space and allowing the original container to be used with the new host, thus saving operating costs. A heating element 213 is set on the outside of the heating pot 21, allowing the heating pot 21 to be heated evenly. The heating element 213 almost completely surrounds the outside of the heating pot 21, resulting in a larger heating area and faster temperature rise of the heating pot 21. The heating of the hookah bowl 8 by the heating pot 21 is more even, avoiding uneven heating and local high-temperature atomization that produces harmful substances. By setting an airflow switch 6, no airflow is generated when smoking, and the heating element 213 is not activated. When smoking, the airflow passes through the air passage 10, triggering the airflow switch. The airflow switch opens, and the heating element 213 starts heating, quickly bringing the temperature back to the set temperature. This makes the heating efficiency faster and allows it to be turned on only when smoking, preventing prolonged heating of the tobacco paste from altering the flavor. This maintains the taste of the smoke and saves energy.
