Description

Technical Field

[0001] This utility model relates to the field of electronic cigarette technology, and in particular to an electronic hookah. Background Technology

[0002] Electronic hookahs are products that combine the features of traditional hookahs and electronic cigarettes. They work by using a built-in battery to power a heating element in the atomizer, which heats the e-liquid, causing it to vaporize and form vapor. This vapor is then filtered through a water tank, during which the temperature decreases and the humidity increases, making it easier for the user to inhale.

[0003] In existing electronic hookahs, the water cup is usually placed above the atomizer. After the vapor is generated, it naturally rises, so as it rises, it can pass smoothly through the water cup for filtration before being inhaled by the user. The whole process conforms to the basic principles of fluid dynamics, ensuring a smooth smoking experience.

[0004] However, to prevent the device's center of gravity from shifting upwards and affecting its stability, water cups are often intentionally made small, resulting in limited water storage capacity that is insufficient for prolonged use. Furthermore, due to space constraints, water cups have complex shapes and numerous crevices, making them difficult to clean and prone to leaving behind dirt and impurities. Utility Model Content

[0045] Electronic hookahs are products that combine the features of traditional hookahs and electronic cigarettes. They work by using a built-in battery to power a heating element in the atomizer, which heats the e-liquid, causing it to vaporize and form vapor. This vapor is then filtered through a water tank, during which the temperature decreases and the humidity increases, making it easier for the user to inhale.

[0046] In existing electronic hookahs, the water cup is usually placed above the atomizer. After the vapor is generated, it naturally rises, so as it rises, it can pass smoothly through the water cup for filtration before being inhaled by the user. The whole process conforms to the basic principles of fluid dynamics, ensuring a smooth smoking experience.

[0047] However, to prevent the device's center of gravity from shifting upwards and affecting its stability, water cups are often intentionally made small, resulting in limited water storage capacity that is insufficient for prolonged use. Furthermore, due to space constraints, water cups have complex shapes and numerous crevices, making them difficult to clean and prone to leaving behind dirt and impurities.

[0048] The main purpose of this invention is to provide an electronic hookah 100, which aims to increase the water storage capacity of the water cup 1 and simplify the shape of the water cup 1 for easy cleaning.

[0049] Please see Figures 1 to 4In one embodiment of this utility model, the electronic hookah 100 includes a water cup 1 and an atomizer 2. The water cup 1 has a receiving groove 11 and an opening 12. The opening 12 is located at the top of the water cup 1 and communicates with the receiving groove 11. The atomizer 2 is closed to the opening 12 and has a heating chamber 2411. The atomizer 2 has a smoke passage 2433 and an inhalation passage 231 spaced apart. The smoke passage 2433 communicates with the heating chamber 2411 and the receiving groove 11 respectively, so as to deliver the smoke generated by the heating chamber 2411 into the receiving groove 11. The inhalation passage 231 communicates with the receiving groove 11 to deliver the smoke in the receiving groove 11 to the user. The distance between the bottom of the smoke passage 2433 and the bottom wall of the water cup 1 is less than the distance between the bottom of the inhalation passage 231 and the bottom wall of the water cup 1.

[0050] In this embodiment, the containment groove 11 inside the water cup 1 provides space for cooling and humidifying the smoke, and holds liquid for filtration. The atomizer 2 is sealed to the opening 12 of the water cup 1 to ensure the airtightness of the smoke during the filtration process. The atomizer 2 has an independent smoke duct 2433 and an inhalation duct 231 inside. The smoke duct 2433 guides the high-temperature smoke generated by the heating chamber 2411 into the containment groove 11 of the water cup 1 for filtration and cooling, while the inhalation duct 231 delivers the treated smoke from the containment groove 11 to the user. The bottom of the smoke duct 2433 is closer to the bottom wall of the water cup 1 than the bottom of the inhalation duct 231, allowing the high-temperature smoke to first pass through the liquid in the water cup 1 for cooling and filtration, and then be inhaled by the user through the higher-positioned inhalation duct 231. It should be noted that the bottom wall of water cup 1 may be a curved surface. In this case, the distance between the bottom of the smoke duct 2433 and the bottom wall of water cup 1 is less than the distance between the bottom of the inhalation duct 231 and the bottom wall of water cup 1. It should be understood that the bottom of the smoke duct 2433 needs to be below the liquid surface, while the inhalation duct 231 should be above the liquid surface.

[0051] Understandably, the technical solution of this utility model places the water cup 1 below the atomizer 2, allowing the smoke generated by the heating chamber 2411 to flow downward through the smoke channel, be filtered by the liquid inside the water cup 1, and then flow upward into the inhalation airway 231 for absorption by the user. This lowers the center of gravity of the electronic hookah 100, ensuring that even with an increased capacity of the water cup 1, the electronic hookah 100 remains stable, thus solving the problem of limited usage time due to the limited capacity of the water cup 1.

[0052] In one implementation, please refer to Figure 2 The atomizer 2 is also provided with a fixing post 21 on the side facing the water cup 1. The fixing post 21 is detachably connected to the bottom wall of the water cup 1.

[0053] In this embodiment, the atomizer 2 is provided with a fixing post 21 that extends into the water cup 1. The fixing post 21 is detachably connected to the water cup 1, which makes it convenient for the user to clean the water cup 1 and add new liquid in a timely manner.

[0054] Understandably, the fixing post 21 and the water cup 1 can be installed via a threaded connection, with one of them having an internal thread and the other having an external thread, thus enabling a threaded connection. Alternatively, the fixing post 21 and the water cup 1 can also be installed via a plug-in connection, with one of them having a protrusion and the other having a groove, thus enabling a plug-in fit to complete the installation.

[0055] In one implementation, please refer to Figures 2 to 4 The bottom of the fixing post 21 is provided with a first magnetic element 211, and the bottom wall of the water cup 1 is provided with a second magnetic element 13. The first magnetic element 211 and the second magnetic element 13 are magnetically attracted to each other, so that the atomizer 2 and the water cup 1 can be detachably connected.

[0056] In this embodiment, a fixing post 21 is provided at the bottom of the atomizer 2, and a first magnetic element 211 is embedded in the bottom of the fixing post 21. At the same time, a second magnetic element 13 is provided at a corresponding position on the bottom wall of the water cup 1. The first magnetic element 211 and the second magnetic element 13 attract each other, so that the atomizer 2 and the water cup 1 can fit tightly together, ensuring that the smoke will not leak from the connection.

[0057] Optionally, a guide structure, such as a tapered guide groove, can be provided on the outside of the magnetic component to facilitate smoother alignment of the magnetic component during assembly and improve the accuracy of the connection.

[0058] Understandably, the magnetic connection not only improves the assembly and disassembly efficiency of the electronic hookah 100, but also enhances its sealing performance. Users can quickly replace the water cup 1 or perform cleaning and maintenance without affecting the performance of the electronic hookah 100, making its use and maintenance more convenient.

[0059] In one implementation, please refer to Figure 2 and Figure 3 The fixed column 21 is arranged along the central axis of the atomizer 2, and the smoke airway 2433 and the inhalation airway 231 are located on opposite sides of the fixed column 21.

[0060] In this embodiment, the fixing post 21 is arranged along the central axis of the atomizer 2, thus ensuring a uniform distribution of the connection force between the atomizer 2 and the water cup 1, avoiding tilting due to eccentric connection. Simultaneously, the central axis arrangement ensures that the center of the magnetic connection coincides with the center of gravity of the electronic hookah 100, enhancing overall stability. The smoke duct 2433 and the inhalation duct 231 are symmetrically arranged on both sides of the fixing post 21. This symmetrical arrangement not only improves the efficiency of smoke treatment but also makes the overall structure more compact, saving internal space.

[0061] Optionally, the shape of the fixing post 21 can be polygonal or circular to accommodate different atomizer 2 structures. Additionally, an anti-slip texture can be provided on the surface of the fixing post 21 to increase friction with the water cup 1 and prevent rotation during use.

[0062] In one implementation, please refer to Figure 3 The atomizer 2 includes a housing 22, a mouthpiece assembly 23, a heating assembly 24, and a battery assembly 25. The housing 22 covers the opening 12 and forms a cavity 221. The mouthpiece assembly 23 is disposed in the housing 22, and one end of the mouthpiece assembly 23 is connected to the receiving groove 11. The other end of the mouthpiece assembly 23 forms a mouthpiece end 232 for user use. The mouthpiece assembly 23 has an inhalation airway 231. The heating assembly 24 is disposed in the housing 22 and spaced apart from the mouthpiece assembly 23. The heating assembly 24 has a heating chamber 2411 and a vapor airway 2433. The battery assembly 25 is disposed in the cavity 221 and is electrically connected to the heating assembly 24.

[0063] In this embodiment, the housing 22 not only serves as a seal but also provides installation space for the battery assembly 25 and other components through its internal cavity 221. One end of the mouthpiece assembly 23 communicates with the receiving groove 11 of the water cup 1, while the other end extends outside the housing 22 to form a mouthpiece end 232 that can be directly used by the user. The internal intake airway 231 ensures that the filtered smoke can be smoothly inhaled by the user. The heating assembly 24 maintains a certain distance from the mouthpiece assembly 23 to avoid the high temperature affecting the mouthpiece assembly 23. At the same time, the heating chamber 2411 and the smoke airway 2433 within the heating assembly 24 are used to generate and guide high-temperature smoke. The battery assembly 25 is installed in the cavity 221 and electrically connected to the heating assembly 24 to provide power.

[0064] Understandably, the modular design not only improves the production efficiency of the electronic hookah 100, but also enhances its reliability, ensuring stability during operation.

[0065] In one implementation, please refer to Figure 3The heating assembly 24 includes a heating chamber 241, a heating element 242, and a connecting pipe 243. The heating chamber 241 is located on the top of the housing 22 and forms a heating cavity 2411. The bottom of the heating chamber 241 is provided with an air hole 2412 that communicates with the heating cavity 2411. The heating element 242 is located in the heating cavity 2411 and is electrically connected to the battery assembly 25. One end of the connecting pipe 243 is connected to the heating chamber 241 through the air hole 2412, and the other end of the connecting pipe 243 extends into the receiving groove 11, forming a smoke duct 2433 inside the connecting pipe 243.

[0066] In this embodiment, the heating chamber 241 is located at the top of the housing 22. Inside the heating chamber 241, a heating cavity 2411 for heating e-liquid and an air vent 2412 communicating with the outside are formed. The heating element 242 is installed inside the heating cavity 2411 and is powered by the battery assembly 25 to heat the e-liquid to a vaporized state. One end of the connecting pipe 243 is connected to the air vent 2412, and the other end extends into the receiving groove 11 of the water cup 1. The smoke duct 2433 formed inside the connecting pipe 243 is used to guide the high-temperature smoke into the liquid for filtration.

[0067] Optionally, the heating chamber 241 can adopt a multi-layer insulation structure to reduce heat loss to the outside of the shell 22 and improve energy utilization efficiency. At the same time, the connecting pipe 243 and the heating chamber 241 can also be configured to be detachably connected for easy cleaning and replacement.

[0068] In one implementation, please refer to Figure 3 The heating chamber 2411 is also provided with a bracket 2413, and the heating element 242 is supported on the bracket 2413 so that there is a gap between the heating element 242 and the bottom wall of the heating chamber 2411. The bottom wall of the heating chamber 2411 is provided with two wiring holes 2414 and an air hole 2412, with the air hole 2412 located between the two wiring holes 2414. The wiring at both ends of the heating element 242 passes through the two wiring holes 2414 respectively and is electrically connected to the battery assembly 25.

[0069] In this embodiment, a support 2413 is provided inside the heating chamber 2411 to support the heating element 242, maintaining a certain gap between the support 2413 and the bottom wall of the heating chamber 2411. This avoids direct contact between the heating element 242 and the bottom wall of the heating chamber 2411, reducing heat conduction to the bottom wall, improving thermal efficiency, and preventing the bottom wall from deforming or being damaged due to overheating. The bottom wall of the heating chamber 2411 has two wiring holes 2414 and one vent 2412. The vent 2412 is located between the two wiring holes 2414, ensuring that flue gas can be discharged smoothly, while providing a channel for the wiring of the heating element 242. The wiring at both ends of the heating element 242 passes through the two wiring holes 2414 respectively and is electrically connected to the battery assembly 25.

[0070] Optionally, the bracket 2413 can be made of a material with high thermal conductivity and low coefficient of expansion, such as ceramic or special alloy, to improve its stability and thermal conductivity in high-temperature environments. Meanwhile, the edges of the wiring hole 2414 and the vent 2412 can also be chamfered to reduce wear on the wiring and connecting pipe 243 and extend their service life.

[0071] In one implementation, please refer to Figure 3 The heating element 242 includes a porous ceramic and a heating wire. The porous ceramic is disposed in the heating cavity 2411, and the heating wire is disposed in the porous ceramic. The heating wire is electrically connected to the battery assembly 25.

[0072] In this embodiment, the heating element 242 includes a porous ceramic and a heating wire. The porous ceramic not only serves as a supporting substrate for the heating wire but also stores a certain amount of e-liquid, which is then evenly distributed around the heating wire through capillary action. When the heating wire is energized and heats up, the e-liquid rapidly vaporizes to form smoke.

[0073] Optionally, the pore size of the porous ceramic can be optimized according to the viscosity and vaporization characteristics of the e-liquid to improve its delivery efficiency and vaporization effect. Meanwhile, the heating wire can be made of a high-resistivity material, such as a nickel-chromium alloy or a titanium alloy, to ensure sufficient heat is generated at a lower current.

[0074] Understandably, the oil storage and guiding functions of porous ceramics ensure that there is always a sufficient supply of e-liquid around the heating wire, preventing dry burning and extending the service life of the heating element 242. At the same time, since the air vents 2412 are located on the bottom wall of the heating chamber 2411, the oil storage function of porous ceramics ensures that the e-liquid is absorbed and does not flow out from the air vents 2412.

[0075] In one implementation, please refer to Figure 3 The connecting pipe 243 includes a first pipe section 2431 and a second pipe section 2432. The two ends of the first pipe section 2431 are connected to an air vent 2412 and the second pipe section 2432, respectively. The side of the second pipe section 2432 facing away from the first pipe section 2431 extends into the receiving groove 11, forming a smoke duct 2433 within both the first and second pipe sections 2431. The second pipe section 2432 is movable relative to the first pipe section 2431 to adjust its length extending into the receiving groove 11.

[0076] In this embodiment, the connecting pipe 243 includes a first pipe section 2431 and a second pipe section 2432. The two ends of the first pipe section 2431 are connected to the air vents 2412 of the heating chamber 241 and the second pipe section 2432, respectively. The other end of the second pipe section 2432 extends into the receiving groove 11 of the water cup 1. The smoke duct 2433 formed inside the first pipe section 2431 and the second pipe section 2432 is used to guide high-temperature smoke from the heating chamber 2411 into the liquid in the water cup 1 for filtration. Simultaneously, the second pipe section 2432 can move relative to the first pipe section 2431. The user can adjust the length of the second pipe section 2432 extending into the receiving groove 11 according to the volume of the liquid in the water cup 1 to optimize the smoke filtration effect.

[0077] Optionally, the second pipe section 2432 can be made of transparent or semi-transparent material so that users can intuitively observe the filtration process of flue gas in the liquid, increasing the fun and interactivity of the use.

[0078] In one implementation, please refer to Figure 3 The battery assembly 25 includes a battery pack 251 and a circuit board 252, both of which are housed within the housing 22. The circuit board 252 is electrically connected to both the battery pack 251 and the heating assembly 24. The battery pack 251 is located between the nozzle assembly 23 and the heating assembly 24, and the circuit board 252 is located on the side of the heating assembly 24 facing away from the nozzle assembly 23.

[0079] In this embodiment, the battery assembly 25 includes a battery pack 251 and a circuit board 252, both of which are installed within the cavity 221 of the atomizer housing 22. The battery pack 251, positioned between the mouthpiece assembly 23 and the heating assembly 24, acts as a counterweight, further lowering the overall center of gravity of the electronic hookah 100 and enhancing its stability. The circuit board 252 is installed on the side of the heating assembly 24 facing away from the mouthpiece assembly 23, and is used to control the power transmission between the battery pack 251 and the heating assembly 24, ensuring that the heating element 242 operates according to a preset program, providing stable smoke output.

[0080] Optionally, the battery pack 251 can use a rechargeable lithium battery and be equipped with a charging interface and a power display device to allow users to understand the battery status and charge it in a timely manner. The circuit board 252 can integrate multiple protection functions, such as overcurrent protection, short circuit protection, and temperature protection, to improve the safety of the electronic hookah 100.

[0081] In one implementation, please refer to Figure 4 The bottom of the water cup 1 is also provided with a cup foot 14, which is used to support the water cup 1 and ensure the stability of the water cup 1.

[0082] In this embodiment, the cup foot 14 is arranged along the periphery of the water cup 1, so that the weight of the water cup 1 and the liquid inside it is evenly transferred to the tabletop, preventing it from falling over due to the shift of the center of gravity.

[0083] Optionally, the cup foot 14 can be integrally molded with the cup 1 to reduce assembly steps. Alternatively, it can be detachable, connected to the bottom of the cup 1 by a snap or thread, to facilitate cleaning or replacement of cup feet 14 of different heights to suit different usage scenarios.

[0084] The above description is merely an exemplary embodiment of the present utility model and does not limit the patent scope of the present utility model. Any equivalent structural transformations made based on the technical concept of the present utility model and the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
