[0002] Existing portable hookah devices heat the hookah atomized material through combustion or contact. They typically have a material cylinder into which the hookah atomized material is placed, and heat is transferred to the interior of the atomized material by heating the cylinder wall. However, due to an unreasonable cylinder structure, the time required for heat to reach the center of the hookah atomized material is relatively long, resulting in a long waiting time for users and affecting the user experience.

[0003] In view of this, the purpose of this utility model is to provide a new technical solution to solve the existing technical problems. Utility Model Content

[0031] The following is in conjunction with the appendix Figure 1-8 The present invention will be further described below.

[0032] The following will clearly and completely describe the concept, specific structure, and technical effects of this utility model in conjunction with embodiments and accompanying drawings, so as to fully understand the purpose, features, and effects of this utility model. Obviously, the described embodiments are only a part of the embodiments of this utility model, not all of them. Other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are all within the scope of protection of this utility model. Furthermore, all connections / linkages involved in the patent do not simply refer to direct contact between components, but rather to the ability to form a better connection structure by adding or reducing connecting accessories according to specific implementation conditions. The various technical features in this utility model can be combined interactively without contradicting each other.

[0033] Reference Figures 1 to 8This utility model provides a portable hookah device, which includes a shell, a heating element assembly 3, a control unit 4, and a battery assembly 5. The shell has a feed inlet 12 and an air inlet 13, and also a suction nozzle 11. The heating element assembly 3 is disposed inside the shell and is used to hold and heat the hookah atomized material 7. Specifically, the heating element assembly 3 includes a material cylinder 31, which holds the hookah atomized material 7. The ratio of the height of the material cylinder 31 to the maximum distance on its axial cross-section is between 1.45 and 5.65, i.e., the aspect ratio of the material cylinder 31 is between 1.45 and 5.65. Gas entering the shell through the air inlet 13 can enter the heating element assembly 3 and react with the hookah atomized material 7 heated by the heating element assembly 3 to produce smoke. The aspect ratio of the feed cylinder 31 is limited to between 1.45 and 5.65, allowing the water vapor atomizer 7 inside the feed cylinder 31 to have a larger contact area with the side wall of the feed cylinder 31. This effectively accelerates the heat conduction rate, thereby accelerating the heating rate of the water vapor atomizer 7. It should be noted that the height and the maximum distance on the axial cross-section refer to the height of the effective volume of the feed cylinder 31 and the maximum distance on the axial cross-section (i.e., the internal height and inner diameter of the feed cylinder 31).

[0034] Reference Figures 1 to 3 The battery assembly 5 and the control unit 4 are housed in the housing. The heating element assembly 3 is electrically connected to the control unit 4, and the battery assembly 5 is electrically connected to the control unit 4. The battery supplies power to the control unit 4, and the control unit 4 is used to control the operation of the heating element assembly 3. The specific structure and control principle of the control unit 4 and the battery assembly 5 can be referred to the existing technology, and will not be elaborated here.

[0035] Furthermore, the maximum distance on the axial cross-section of the barrel 31 is between 13.8 mm and 20.7 mm. The maximum distance on the axial cross-section is defined as the length of the line connecting the two farthest points on the cross-section. For example, when the axial cross-section of the barrel 31 is circular, the maximum distance is the diameter of the circle; when the axial cross-section of the barrel 31 is square, the maximum distance is the length of the diagonal of the square; when the axial cross-section of the barrel 31 is irregular, the maximum distance is the distance between the two farthest points on the irregular cross-section. The aspect ratio of the material cylinder 31 is limited to between 1.45 and 5.65, and the maximum distance on the axial cross-section of the material cylinder 31 is limited to between 13.8 mm and 20.7 mm. This makes the structure of the material cylinder 31 of this utility model relatively slender, which allows for a large contact area with the heating element assembly. The distance from the wall of the material cylinder 31 to the center of the water vapor atomizer 7 is also appropriate, which can effectively shorten the time for heat to be transferred from the material cylinder 31 to the center of the water vapor atomizer 7. During use, the water vapor atomizer 7 inside the material cylinder 31 can be fully heated, which can effectively speed up the heating speed while ensuring the flavor of the smoke and effectively shorten the user's waiting time. In addition, the material cylinder 31 is of appropriate size, making it convenient for users to use and carry.

[0036] Reference Figures 6 to 8 The preheating time and taste evaluation were recorded with different aspect ratios and different maximum axial cross sections when the volume of the barrel 31 was 10ml. It can be seen from the figure that when the size of the barrel 31 is within the size range defined by this utility model, its preheating time and taste evaluation have relatively ideal values. Due to the size outside the scope defined by this utility model, there are problems such as excessively long preheating time or poor taste.

[0037] Reference Figures 2 to 4 Furthermore, the sidewalls of the feed cylinder 31 are inclined, and the axial cross-section of the feed cylinder 31 decreases from its opening to its bottom surface. For example, in some embodiments, the feed cylinder 31 has a hollow frustum structure; in some embodiments, the feed cylinder 31 has a hollow right frustum structure; and in some embodiments, the feed cylinder 31 can also have an irregular frustum structure. In this embodiment, the feed cylinder 31 has a frustum structure. Correspondingly, the heating element assembly 3 and the water vapor atomizer 7 placed in the feed cylinder 31 are also configured to match the shape of the feed cylinder 31. With this configuration, the radius of the upper end of the feed cylinder 31 is larger than the radius of the lower end. Under the action of gravity, the water vapor atomizer 7 placed in the feed cylinder 31 will slide downwards to a state of close contact with the wall of the feed cylinder 31, so that the water vapor atomizer 7 can fit tightly against the wall of the feed cylinder 31, which is beneficial to the heat transfer between the two. Similarly, the gap between the feed cylinder 31 and the heating element in the heating element assembly 3 will also be reduced accordingly, thereby improving the heating effect. In addition, since the material cylinder 31 has an inclined wall structure, when it is necessary to pour out the water vapor atomized material 7 inside the material cylinder 31, tilting the machine body will make it easier for the water vapor atomized material 7 to slide out along the wall of the material cylinder 31, which is convenient for users to operate and reduces the difficulty of pouring and recycling the water vapor atomized material 7.

[0038] The heating element assembly 3 is used to hold and heat the water vapor atomizer 7. Specifically, the barrel 31 is connected to the feed inlet 12. The water vapor atomizer 7 can be put into the barrel 31 of the heating element assembly through the feed inlet 12, and then the heating element assembly 3 heats the water vapor atomizer 7. The heating of the heating element assembly 3 can be achieved by heating with a heating wire or the like. The barrel 31 can be made of at least one of aluminum, copper, zinc, nickel, silver, and combinations thereof. The barrel 31 with good thermal conductivity is conducive to transferring more and faster heat to the water vapor atomizer 7, which is beneficial to further accelerate the heating rate of the water vapor atomizer 7.

[0039] Reference Figures 2 to 5Furthermore, the outer casing includes an upper casing 1 and a lower casing 2 connected together. An air inlet 13 and a feed inlet 12 are both located on the upper casing 1, communicating with the interior of the upper casing 1. The suction nozzle 11 is located on the side of the upper casing 1 away from the lower casing 2. The control unit 4 and the battery assembly 5 are both located inside the upper casing 1. When the user performs a suction action, external gas can enter the heating element assembly 3 through the air inlet 13 to react with the water vapor atomizer 7 therein to generate smoke. The upper casing 1 also has an air outlet channel 14, which connects the lower casing 2 and the suction nozzle 11. The air outlet channel 14 is used to conduct the smoke generated after heating the water vapor atomizer 7 to the suction nozzle 11. When the user suctions through the suction nozzle 11, external gas enters the heating element assembly 3 through the air inlet 13 and reacts with the heated water vapor atomizer 7 to generate smoke. The smoke is then transported to the lower casing 2 and delivered to the suction nozzle 11 via the air outlet channel 14. In this embodiment, a filter screen 131 is provided at the air inlet 13 to effectively reduce the possibility of larger foreign objects entering the housing through the air inlet 13. The flow direction of smoke in the air outlet channel 14 is shown by the arrow in the figure.

[0040] The heating element assembly 3 is connected to an air pipe 32, which extends into the lower housing 2. Smoke generated within the heating element assembly 3 is transmitted to the lower housing 2 via the air pipe 32. The lower housing 2 contains a liquid 22, which can be water or similar substances. The liquid 22 filters the smoke generated by the water vaporizer 7, reducing harmful substances such as tar and nicotine in the smoke. Simultaneously, the liquid 22 also helps cool the smoke, lowering the temperature of the inhaled smoke, reducing irritation to the respiratory tract, and improving the user experience.

[0041] Furthermore, a heat insulation layer 33 is provided around the heating element component 3 to insulate and keep the heating element component 3 warm, thereby reducing heat loss from the heating element component 3 and effectively ensuring the heating efficiency of the heating element component 3, thus improving the user experience.

[0042] Furthermore, the upper housing 1 and the lower housing 2 are detachably connected. In this embodiment, the upper housing 1 and the lower housing 2 are fixed together by magnetic attraction. The magnetic fixation between the upper housing 1 and the lower housing 2 makes disassembly more convenient and facilitates the addition and replacement of the liquid 22 inside the lower housing 2.

[0043] Furthermore, the lower housing 2 has a lower air port 21, from which the smoke passing through the liquid 22 is output. The upper housing 1 has an upper air port 15 that communicates with the air outlet channel 14, and the upper air port 15 is connected to the lower air port 21. The smoke enters the air outlet channel 14 from the lower air port 21 and is then transmitted to the suction nozzle 11 for the user to inhale.

[0044] In this embodiment, the lower housing 2 has a through hole 23 for inserting an air pipe 32 into the lower housing 2. During use, the liquid 22 inside the lower housing 2 can be added or replaced through the through hole 23. To ensure the sealing of the connection between the lower housing 2 and the air pipe 32, a sealing ring can be fitted over the air pipe 32. The sealing ring and the through hole 23 are press-fitted to achieve a seal at the connection.

[0045] Furthermore, it also includes a feed cover 6, which is detachably installed on the feed inlet 12 to close the feed inlet 12.

[0046] Furthermore, the suction nozzle 11 is foldable and mounted on the upper housing 1. By setting the suction nozzle 11 as a foldable structure, it can be folded up and stored when carried, making the device more portable. In addition, in order to ensure the sealing of the connection between the suction nozzle 11 and the air outlet channel 14, a sealing gasket is provided at the opening of the air outlet channel 14.

[0047] Furthermore, the upper surface of the feed cover 6 is provided with a receiving groove 61, into which the suction nozzle 11 can be flipped to be stored. Storing the suction nozzle 11 into the receiving groove 61 further improves the portability of the device and makes it convenient for users to carry.

[0048] The above is a detailed description of the preferred embodiments of the present utility model. However, the present utility model is not limited to the described embodiments. Those skilled in the art can make various equivalent modifications or substitutions without departing from the spirit of the present utility model. All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
