Description

Technical Field

[0001] This utility model relates to the field of electronic cigarettes, and more particularly to a portable hookah. Background Technology

[0002] Existing portable hookah devices typically include a water tank, with the mouthpiece and the air outlet of the water tank usually located on the same end. This leads to a situation where, during use, the airflow entering the water tank causes the liquid to fluctuate. Because the mouthpiece and air outlet are on the same side, this fluctuating liquid is more easily inhaled into the user's mouth. This is especially true when the user uses the device at an angle, as the liquid level near the mouthpiece rises further, significantly increasing the risk of liquid being inhaled into the mouth. Utility Model Content

[0003] In order to overcome the shortcomings of the prior art, this utility model provides a portable hookah that can effectively prevent liquid from being inhaled into the user's mouth.

[0004] The technical solution adopted by this utility model to solve its technical problem is:

[0005] A portable hookah includes: a water tank having a first end and a second end opposite to each other; an air outlet channel located on the top of the water tank, having a first air outlet and a second air outlet; and an air inlet channel located on the top of the water tank, having a first air inlet and a smoke guide tube extending into the water tank, the outlet end of the smoke guide tube forming a second air inlet and being immersed in the liquid in the water tank; wherein the first air outlet is located at the first end, the second air inlet is located at the second end, and the second end is the mouthpiece end.

[0006] Furthermore, the second air inlet includes a plurality of micropores distributed at the outlet end of the smoke guide tube.

[0007] Furthermore, the micropore includes a first micropore and a second micropore, wherein the diameter of the first micropore is larger than the diameter of the second micropore, the first micropore is located in the middle of the outlet end of the smoke guide tube, and the second micropore is located in the edge region of the outlet end of the smoke guide tube.

[0008] Furthermore, the outlet end of the smoke guide pipe forms an inclined surface that forms an angle of 15-45 degrees with the horizontal plane and faces the first end, and the second air inlet is disposed on the inclined surface.

[0009] Furthermore, a liquid level separation hood is provided inside the water tank, the bottom of which is connected to the water tank, and the smoke guide pipe is inserted into the liquid level separation hood so that the second air inlet is located inside the liquid level separation hood.

[0010] Furthermore, the liquid level separation hood is cylindrical with an inner diameter of D1, and the outer diameter of the smoke guide pipe is D2, wherein the ratio of D1 to D2 is 1.5-2.5:1.

[0011] Furthermore, it also includes an integrated atomizing component and a mouthpiece component; wherein the water tank is separately connected to the atomizing component and the mouthpiece component.

[0012] Furthermore, the first air inlet of the air inlet channel is connected to the atomizing component; the first air outlet is located inside the water tank, and the second air outlet is connected to the mouthpiece component; the smoke generated by the atomizing component passes through the air inlet channel and the second air inlet in sequence to contact the liquid, and then passes through the first air outlet and the air outlet channel, and is discharged from the second air outlet.

[0013] Furthermore, the first air outlet and the second air inlet are respectively disposed on the outer surface of the top of the water tank; a sealing cover is also disposed on the outer surface of the top of the water tank, and the sealing cover is rotatably connected to the top of the water tank; the sealing cover has a first guide hole and a second guide hole, which correspond to the positions of the first air outlet and the second air inlet, respectively; rotating the sealing cover can make the first guide hole and the second guide hole connect with or close the first air outlet and the second air inlet.

[0014] Furthermore, the sealing cover is provided with a first fixing part, and the top of the water tank is provided with a second fixing part that cooperates with the first fixing part; the first guide hole and the second guide hole are circumferentially distributed along the axis of the first fixing part. When the sealing cover is rotated, the first guide hole and the second guide hole move circumferentially to achieve communication or closure with the first air outlet and the second air inlet.

[0015] The beneficial effects of this utility model are:

[0016] This invention addresses the issue of liquid level by placing the first air outlet at the first end of the water tank and the second air inlet at the second end, located at the mouthpiece end. This separation of the air outlet and inlet at opposite ends of the liquid storage chamber effectively increases the distance between the liquid level and the air outlet. This not only prevents liquid from being inhaled into the user's mouth during normal use, but also ensures that even when the user uses the device at an angle, if the liquid level rises on the side closer to the mouthpiece, the air outlet, located at the other end away from the mouthpiece, effectively prevents liquid from entering the air outlet channel. Furthermore, the disturbance caused by the liquid provides good sound feedback to the user, enhancing both safety and user experience. Attached Figure Description

[0034] 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.

[0035] Reference Figure 1-4 A portable hookah includes a water tank 100, an exhaust channel 130, and an intake channel 140. The water tank 100 has a first end 110 and a second end 120 opposite to each other; the exhaust channel 130 has a first exhaust port 131 and a second exhaust port 132; referring to Figures 5-7, the intake channel 140 has a first intake port 141 and a guide pipe 142 extending into the water tank 100, the outlet end of the guide pipe 142 forming a second intake port 143 and immersed in the liquid in the water tank 100; wherein the exhaust channel 130 and the intake channel 140 are both located on the top of the water tank 100, the first exhaust port 131 is located at the first end 110, the second intake port 143 is located at the second end 120, and the second end 120 is the mouthpiece end 410.

[0036] Understandably, when a user uses this portable hookah, they inhale through the mouthpiece 410. The airflow enters the air intake channel 140 through the first air inlet 141, passes through the smoke guide tube 142, and enters the liquid in the water tank 100. After generating bubbles, the airflow flows out through the second air inlet 143, then through the first air outlet 131 of the air outlet channel 130 to the second air outlet 132, and finally flows out from the mouthpiece 410. By positioning the first air outlet 131 and the second air inlet 143 at opposite ends of the water tank 100, the distance between the liquid surface and the air outlet is effectively increased, thereby reducing the risk of liquid being inhaled into the user's mouth.

[0037] It should be noted that the water tank 100 can be a cylindrical structure with a circular, square, or elliptical cross-section, and a liquid inlet is provided on one side of the water tank 100. Referring to Figures 4, 8, and 9, a rubber stopper 170 is provided on the liquid inlet 160. Liquid can be added to or replaced into the water tank 100 through the liquid inlet 160. During use, the liquid inlet 160 is sealed with the rubber stopper 170 to prevent liquid leakage. For example, when it is necessary to add liquid to the water tank 100, the user can remove the rubber stopper 170, add an appropriate amount of liquid through the liquid inlet 160, and after adding, reinsert the rubber stopper 170 into the liquid inlet 160 to ensure the water tank 100 is sealed and prevent liquid leakage during use.

[0038] In some embodiments, refer to Figure 1-3 The portable hookah also includes an integrated atomizing component 300 and a mouthpiece component 400. These two components are connected to the water tank 100 separately. This separate connection design facilitates component replacement, maintenance, and portability for users. The separate connection can be achieved in various ways, such as snap-fit ​​or magnetic connection. When using magnetic connection, the bottom of the atomizing component 300 and the mouthpiece component 400 has multiple magnetic points, and corresponding magnets are also located in the water tank 100. The components are connected by the mutual attraction of these magnets. For example, when the user needs to use the portable hookah, they simply align the atomizing component 300 and the mouthpiece component 400 with the corresponding magnet positions on the water tank 100, and the magnetic attraction will automatically bring the components together to form a complete device. When cleaning or replacing components is required, the user can easily separate these components, which facilitates daily maintenance and improves the portability of the device.

[0039] Furthermore, in the airflow path design of the portable hookah, the first air inlet 141 of the air inlet channel 140 is connected to the atomizing component 300, while the first air outlet 131 is located inside the water tank 100, and the second air outlet 132 is connected to the mouthpiece assembly 400, forming a complete airflow channel system. When the user uses the portable hookah, the smoke generated by the atomizing component 300 first enters the first air inlet 141, and then flows through the air inlet channel 140 to the second air inlet 143. Since the second air inlet 143 is immersed in the liquid in the water tank 100, the smoke and liquid are in full contact. During this process, the smoke is filtered and regulated by the liquid. The smoke after being filtered by the liquid rises to the first air outlet 131 in the water tank 100, and then flows through the air outlet channel 130 to the second air outlet 132, and is finally discharged from the second air outlet 132 connected to the mouthpiece assembly 400. For example, when a user inhales through the mouthpiece assembly 400, it drives the entire airflow system to operate, and the smoke generated by the atomizing assembly 300 flows along the above path, providing a better smoking experience after being filtered by liquid.

[0040] In some embodiments, refer to Figure 5 , 7 The second air inlet 143 includes a plurality of micropores distributed at the outlet end of the smoke guide pipe 142.

[0041] These micropores are distributed at the outlet end of the smoke guide tube 142. When smoke reaches the end of the smoke guide tube 142 through the air intake channel 140, it is dispersed into finer bubbles through these tiny pores and enters the liquid. In use, the smoke generated by the atomizing component 300 enters the air intake channel 140 through the first air intake hole 141, and then flows into the smoke guide tube 142. When the smoke reaches the outlet end of the smoke guide tube 142, it is dispersed into a large number of fine bubbles through these evenly distributed micropores. These fine bubbles have a larger contact area with the liquid, which not only filters the smoke more effectively, but also produces a slight bubbling sound when the bubbles burst, improving the user experience. At the same time, the design of multiple micropores can also prevent the problem of liquid splashing caused by a single bubble being too large.

[0042] Furthermore, the micropores include a first micropore and a second micropore, wherein the diameter of the first micropore is larger than the diameter of the second micropore. The first micropore is located in the middle of the outlet end of the smoke guide tube 142, and the second micropore is located in the edge region of the outlet end of the smoke guide tube 142. It can be understood that the micropore design at the outlet end of the portable hookah smoke guide tube 142 employs two micropore structures with different diameters, including a larger-diameter first micropore and a smaller-diameter second micropore. The first micropore is located in the middle of the outlet end of the smoke guide tube 142, while the second micropore is distributed in the edge region of the outlet end of the smoke guide tube 142. This arrangement creates a unique bubble distribution effect. When in use, after the smoke reaches the outlet end of the smoke guide tube 142 through the air intake channel 140, the first micropore in the middle, due to its larger diameter, will generate relatively large bubbles. These bubbles can provide the main airflow channel, while the second micropore in the edge area, due to its smaller diameter, will generate even smaller bubbles. These smaller bubbles can provide a more thorough filtration effect. The two types of bubbles of different sizes work together to ensure smooth airflow and improve the filtration effect, while also producing a unique foam visual effect and water bubble sound.

[0043] Furthermore, the diameter of the first micropore ranges from 0.8 mm to 1.2 mm, and the diameter of the second micropore ranges from 0.3 mm to 0.7 mm.

[0044] In some embodiments, the diameter of the micropores gradually decreases linearly from the center to the edge region. For example, the diameter of the micropore at the center of the outlet end of the smoke guide tube 142 is 1.2 mm. From the center outwards, the micropore diameter decreases by 0.1 mm at every 1 mm concentric circle, finally decreasing to 0.3 mm at the edge region. During use, when smoke passes through this linearly decreasing micropore distribution, it forms a layer of bubbles of varying sizes in the liquid. In the central region, due to the larger micropore diameter, bubbles with a diameter of approximately 1.2 mm form. As the smoke diffuses outwards, the bubble size gradually decreases, eventually forming tiny bubbles of approximately 0.3 mm at the edge region. This gradual bubble distribution not only achieves a uniform suction effect but also...

[0045] In some embodiments, the outlet end of the smoke guide tube 142 forms an inclined surface (not shown in the figure), which forms an angle of 15-45 degrees with the horizontal plane, and the inclined direction is towards the first end 110. The aforementioned second air inlet 143 is provided on this inclined surface. Due to the inclined design of the outlet end of the smoke guide tube 142, when smoke enters the liquid through the second air inlet 143, it will generate directional bubble flow. This inclined angle design prevents the bubbles from moving directly upward, but instead causes them to deflect towards the first end 110, thereby prolonging the movement path and residence time of the bubbles in the liquid. For example, when the inclined angle is 30 degrees, the bubbles will move along this angle. This design not only increases the contact time between the smoke and the liquid and improves the filtration effect, but also prevents the liquid splashing caused by the direct rise of bubbles, making the entire smoking process smoother.

[0046] In some embodiments, refer to Figure 2 , 3 8, 10. A liquid level separation cover 150 is installed inside the water tank 100. The bottom of the liquid level separation cover 150 is in communication with the water tank 100. The smoke guide pipe 142 is inserted into the internal space of the liquid level separation cover 150, so that the outlet end with the inclined surface and the second air inlet 143 on it are located inside the liquid level separation cover 150. The smoke released by the smoke guide tube 142 through the second air inlet 143 first forms bubbles in the liquid level separation hood 150. These bubbles move and are filtered within the confined space of the liquid level separation hood 150. Since the bottom of the liquid level separation hood 150 is connected to the water tank 100, the liquid level in the liquid level separation hood 150 will be consistent with that in the water tank 100. When the bubbles rise to the liquid surface, due to the obstruction of the liquid level separation hood 150, the bubbles will not directly enter the smoke channel, but will undergo secondary separation within the liquid level separation hood 150. This design not only provides a more stable filtration effect, but also effectively prevents liquid from splashing into the smoke channel as the bubbles rise, thereby ensuring that the user will not inhale droplets during use.

[0047] Furthermore, when the smoke guide pipe 142 is inserted into the liquid level separation hood 150, so that the second air inlet 143 is located inside the liquid level separation hood 150, the liquid level separation hood 150 forms a closed small space, and the bursting of bubbles in this confined space produces a clearer sound. The smoke released from the second air inlet 143 forms bubbles inside the liquid level separation hood 150. As these bubbles rise, due to the space limitation of the liquid level separation hood 150, the sound waves generated when the bubbles burst will be reflected and resonated multiple times inside the hood, thus forming a louder and crisper sound of bursting bubbles. This "gurgling" water sound not only enhances the user experience, but also allows the user to judge whether the inhalation intensity is appropriate through sound feedback. At the same time, since the bottom of the liquid level separation hood 150 is connected to the water tank 100, this sound effect can be generated continuously and stably.

[0048] Furthermore, the liquid level separation cover 150 adopts a cylindrical structure, with its inner diameter D1 maintaining a ratio of 1.5-2.5:1 to the outer diameter D2 of the inserted smoke guide tube 142. For example, when the outer diameter D2 of the smoke guide tube 142 is 8mm, the inner diameter D1 of the liquid level separation cover 150 should be between 12mm and 20mm. This size ratio ensures that the smoke guide tube 142 is stably inserted into the liquid level separation cover 150, while also leaving a sufficient annular space between the wall of the smoke guide tube 142 and the inner wall of the liquid level separation cover 150. When the user uses the portable hookah, the bubbles generated from the second air inlet 143 will move within this annular space. This prevents the bubble movement trajectory from becoming uncontrollable due to excessive space, and also prevents the bubbles from rising and separating normally due to insufficient space, thus ensuring the smoke filtration effect and a smooth user experience.

[0049] Similarly, when the outer diameter D2 of the flue pipe 142 is 8mm, the inner diameter D15 of the liquid level separation hood 150 is 12-20mm. This annular space design allows the sound waves generated by the bursting of bubbles to form a directional reflection within the cylindrical space. Due to the moderate space size, the sound wave energy will not be excessively dispersed and weakened due to the space being too large, nor will the sound generation be affected due to the space being too small and restricting the movement of bubbles. Thus, a clear and loud "gurgling" sound can be produced when the bubbles burst.

[0050] In some embodiments, refer to Figure 4The first air outlet 131 and the second air inlet 143 are located on the outer surface of the top of the water tank 100, and a rotatable sealing cover 200 is installed on this outer surface. The sealing cover 200 has a first guide hole 210 and a second guide hole 220 corresponding to the positions of the first air outlet 131 and the second air inlet 143. For example, when the user needs to use the portable hookah, the sealing cover 200 can be rotated to precisely align the first guide hole 210 and the second guide hole 220 with the first air outlet 131 and the second air inlet 143, thus opening the airflow channel for easy use. After use, the sealing cover 200 can be rotated again to offset the two sets of holes, closing the airflow channel and achieving a sealing effect. This design is not only convenient to operate but also provides a reliable seal, effectively preventing liquid leakage during transport and preventing the entry of external dust when not in use, thus improving the safety and portability of the portable hookah. When the sealing cover 200 is closed, even if the hookah device is tilted, liquid will not leak from these channels.

[0051] Furthermore, refer to Figure 4 The sealing cover 200 is provided with a first fixing part 230, which is connected to the second fixing part 240 on the top of the water tank 100, so that the sealing cover 200 can rotate stably around the fixed axis. The first guide hole 210 and the second guide hole 220 are circumferentially distributed on the sealing cover 200 along the axis of the first fixing part 230, so that the channels can move in a circle as the sealing cover 200 rotates. For example, when the user needs to use the portable hookah, rotating the sealing cover 200 will cause the first guide hole 210 and the second guide hole 220 to move along the circumferential trajectory to a position that completely coincides with the first air outlet 131 and the second air inlet 143, at which time the airflow channel is fully open; when sealing is required, simply rotate the sealing cover 200 in the opposite direction, and the two sets of channels will be misaligned to form a completely sealed state. This design is similar to the switch structure of a traditional kettle lid. The fixed axis design ensures the smoothness and precision of the rotation process, while the circumferentially distributed channels make the switch action smoother and allow for precise control of the opening angle, ensuring both smooth operation and a tight seal when closed.

[0052] In some embodiments, the first fixing part 230 and the second fixing part 240 can be implemented using a convex shaft and a groove. For example, the first fixing part 230 can be a cylindrical convex shaft located at the center of the sealing cap 200. The bottom of this convex shaft can be designed as a slightly enlarged stepped structure, while the second fixing part 240 is a circular groove located at the corresponding position on the top of the water tank 100. The groove has a ring of slots inside to accommodate the step at the bottom of the convex shaft. When the convex shaft is inserted into the groove, the stepped structure will be engaged in the slots, forming a rotatable but not easily detached connection. Another implementation is that the first fixing part 230 can be designed as a hollow sleeve structure, while the second fixing part 240 is a matching fixing post. The two are fixed by interference fit or snap-fit, similar to the rotating structure of a thermos lid. This design ensures stable rotation of the sealing cap 200 without accidental detachment during use, and facilitates disassembly and cleaning, ensuring convenience and safety during the use and maintenance of the portable hookah.

All such equivalent modifications or substitutions are included within the scope defined by the claims of this application.
