A portable hookah

Abstract

The present invention discloses a portable hookah, comprising: a water tank, an air outlet channel and an air inlet channel. The air outlet channel has a first air outlet hole and a second air outlet hole; the air inlet channel has a first air inlet hole and a smoke guide pipe extending into the water tank, and the outlet end of the smoke guide pipe forms a second air inlet hole and is immersed in the liquid in the water tank. By arranging the first air outlet hole and the second air inlet hole at the first end and the second end of the water tank respectively, the air outlet end and the air inlet end are arranged at the opposite ends of the liquid storage chamber, which effectively increases the distance between the liquid surface and the air outlet hole. Not only can it prevent liquid from being sucked into the user's mouth in normal use, but also when the user uses the device at an inclined angle, even if the liquid level on the side close to the mouthpiece end rises, since the air outlet hole is located at the other end away from the mouthpiece end, it can still effectively prevent liquid from entering the air outlet channel.

Description

Technical Field

[0001] The present invention relates to the field of electronic cigarettes, and in particular to a portable hookah. Background Art

[0002] Existing portable hookah devices usually include a water tank, in which the mouthpiece end and the air outlet end of the water tank are usually arranged at the same end. As a result, during use, when the user inhales, the airflow entering the water tank causes the liquid to fluctuate. Since the mouthpiece end and the air outlet end are located on the same side, the fluctuating liquid is more likely to be sucked into the user's mouth. In particular, when the user uses the device at an inclined angle, the liquid level near the mouthpiece end will further rise, greatly increasing the risk of liquid being sucked into the mouth. Summary of the invention

[0034] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by technicians in this field without creative work are all within the scope of protection of the present invention. In addition, all the connection / connection relationships involved in the patent do not refer to the direct connection of components, but refer to the formation of a better connection structure by adding or reducing connection accessories according to the specific implementation situation. The various technical features in the invention can be combined interchangeably without conflicting with each other.

[0035] Reference Figure 1-4 A portable hookah includes a water tank 100, an air outlet channel 130 and an air inlet channel 140. The water tank 100 is provided with a first end 110 and a second end 120 opposite to each other; the air outlet channel 130 has a first air outlet hole 131 and a second air outlet hole 132; referring to FIGS. 5-7 , the air inlet channel 140 has a first air inlet hole 141 and a smoke guide tube 142 extending into the water tank 100, and the outlet end of the smoke guide tube 142 forms a second air inlet hole 143 and is immersed in the liquid in the water tank 100; wherein the air outlet channel 130 and the air inlet channel 140 are both arranged at the top of the water tank 100, the first air outlet hole 131 is located at the first end 110, the second air inlet hole 143 is located at the second end 120, and the second end 120 is a mouthpiece end 410.

[0036] It is understandable that when the user uses the portable hookah, he inhales through the mouthpiece end 410, and the airflow enters the air inlet channel 140 from the first air inlet hole 141, enters the liquid in the water tank 100 through the smoke guide pipe 142, and flows out from the second air inlet hole 143 after generating bubbles, and then flows to the second air outlet hole 132 through the first air outlet hole 131 of the air outlet channel 130, and finally flows out from the mouthpiece end 410. By locating the first air outlet hole 131 and the second air inlet hole 143 at both ends of the water tank 100, the distance between the liquid surface and the air outlet hole 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 columnar structure with a circular, square, or elliptical cross section, and a liquid injection port is provided on one side of the water tank 100. Referring to FIGS. 4, 8, and 9, a rubber plug 170 is provided on the liquid injection port 160 to match the liquid injection port 160. Liquid can be added or replaced into the water tank 100 through the liquid injection port 160. When in use, the liquid injection port 160 is sealed by the rubber plug 170 to prevent liquid leakage. For example, when liquid needs to be added into the water tank 100, the user can remove the rubber plug 170, add an appropriate amount of liquid through the liquid injection port 160, and after the addition is completed, the rubber plug 170 is re-inserted into the liquid injection port 160 to ensure the sealing of the water tank 100 and avoid liquid leakage during use.

[0038] In some embodiments, reference Figure 1-3 The portable hookah also includes an integrally connected atomizer assembly 300 and a cigarette holder assembly 400. These two components are connected to the water tank 100 in a split-type connection. This split-type connection design makes it easy for users to replace, maintain and carry the components. The split-type connection can be achieved in a variety of ways, such as a snap connection or a magnetic connection. When the magnetic connection method is adopted, a plurality of magnetic points are provided at the bottom of the atomizer assembly 300 and the cigarette holder assembly 400, and a plurality of corresponding magnets are also provided at the corresponding positions of the water tank 100. The connection between the components can be achieved through the mutual attraction of these magnets. For example, when the user needs to use the portable hookah, he only needs to align the atomizer assembly 300 and the cigarette holder assembly 400 with the corresponding magnet positions on the water tank 100, and the attraction of the magnet will automatically attract the various components together to form a complete device; when the components need to be cleaned or replaced, the user can easily separate these components, which is convenient for daily maintenance and improves the portability of the device.

[0039] Furthermore, in the design of the airflow path of the portable hookah, the first air inlet 141 of the air inlet channel 140 is connected to the atomizer assembly 300, while the first air outlet 131 is arranged 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 atomizer assembly 300 first enters the first air inlet 141, and then flows to the second air inlet 143 through the air inlet channel 140. Since the second air inlet 143 is immersed in the liquid in the water tank 100, the smoke is fully in contact with the liquid, and in this process the smoke is filtered and regulated by the liquid; the smoke filtered by the liquid rises to the first air outlet 131 in the water tank 100, and then flows to the second air outlet 132 through the air outlet channel 130, and finally is discharged from the second air outlet 132 connected to the mouthpiece assembly 400. For example, when a user inhales through the mouthpiece assembly 400, the entire airflow system will be driven to operate, and the smoke generated by the atomizer assembly 300 will flow along the above path, providing a better smoking experience after being filtered by the liquid.

[0040] In some embodiments, reference Figure 5 , 7 The second air inlet 143 includes a plurality of micro holes 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 the smoke reaches the end of the smoke guide tube 142 through the air inlet channel 140, it will be dispersed into smaller bubbles through these tiny holes and enter the liquid. When in use, the smoke generated by the atomizer assembly 300 enters the air inlet channel 140 through the first air inlet 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 will be dispersed into a large number of small bubbles through these evenly distributed micropores. These small bubbles have a larger contact area with the liquid, which can not only filter the smoke more fully, but also produce a slight bubbling sound through the bursting of the bubbles, thereby 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] Further, 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 area of ​​the outlet end of the smoke guide tube 142. It can be understood that two micropore structures with different diameters are used in the micropore design of the outlet end of the portable hookah smoke guide tube 142, including a first micropore with a larger diameter and a second micropore with a smaller diameter, wherein the first micropore is arranged in the middle of the outlet end of the smoke guide tube 142, and the second micropore is distributed in the edge area of ​​the outlet end of the smoke guide tube 142, and this layout forms a special bubble distribution effect. During use, after the smoke reaches the outlet end of the smoke guide tube 142 through the air inlet channel 140, the first micropores in the middle will produce relatively large bubbles due to their larger diameter, and these bubbles can provide the main airflow channel, while the second micropores in the edge area will produce smaller bubbles due to their smaller diameter, and these fine bubbles can provide a more sufficient filtering effect. The two different sizes of bubbles work together to ensure the smoothness of the airflow and improve the filtering effect, while also producing a unique foam visual effect and bubbling sound.

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

[0044] In some embodiments, the diameter of the micropores decreases linearly from the middle to the edge area. For example, the diameter of the micropores at the center of the outlet end of the smoke guide tube 142 is 1.2 mm. From the center to the outside, the diameter of the micropores decreases by 0.1 mm on the concentric circles of 1 mm, and finally the diameter of the micropores in the edge area decreases to 0.3 mm. When in use, when smoke passes through this linearly decreasing micropore distribution, a bubble layer with a gradual size change will be formed in the liquid. Bubbles with a diameter of about 1.2 mm will be formed in the center area due to the larger diameter of the micropores. When diffusing outward, the bubble size gradually decreases, and finally small bubbles of about 0.3 mm are formed in the edge area. This gradual bubble distribution can not only achieve a uniform suction resistance effect.

[0045] In some embodiments, the outlet end of the smoke guide tube 142 forms an inclined surface (not shown in the figure), and the inclined surface forms an angle of 15-45 degrees with the horizontal plane, and the inclined direction is toward the first end 110. The aforementioned second air inlet 143 is arranged on this inclined surface. Due to the inclined design of the outlet end of the smoke guide tube 142, when the smoke enters the liquid through the second air inlet 143, a directional bubble flow will be generated. This inclined angle design makes the bubbles not move directly upward, but will produce a deviation toward the first end 110, thereby extending 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 direction. This design not only increases the contact time between the smoke and the liquid and improves the filtering effect, but also prevents the liquid splashing caused by the direct rise of the bubbles, making the entire smoking process smoother.

[0046] In some embodiments, reference Figure 2 , 3 , 8, 10, a liquid level separation cover 150 is installed inside the water tank 100, and the bottom of the liquid level separation cover 150 is kept in communication with the water tank 100, and 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 thereon are both located inside the liquid level separation cover 150. The smoke released by the smoke guide pipe 142 through the second air inlet 143 will first form bubbles in the liquid level separation cover 150, and these bubbles will move and be filtered in the restricted space of the liquid level separation cover 150. Since the bottom of the liquid level separation cover 150 is connected to the water tank 100, the liquid level in the liquid level separation cover 150 will be consistent with the water tank 100. When the bubbles rise to the liquid surface, due to the obstruction of the liquid level separation cover 150, the bubbles will not directly enter the smoking channel, but will undergo secondary separation in the liquid level separation cover 150. This design can not only provide a more stable filtering effect, but also effectively prevent liquid from splashing into the smoking channel as the bubbles rise, thereby ensuring that the user will not inhale droplets during use.

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

[0048] Furthermore, the liquid level separation cover 150 adopts a cylindrical structure, and the ratio between its inner diameter D1 and the outer diameter D2 of the smoke guide tube 142 inserted therein is maintained at 1.5-2.5:1. 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 can not only ensure that the smoke guide tube 142 is stably inserted into the liquid level separation cover 150, but also leave a sufficient annular space between the wall surface 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 in this annular space, and the bubble movement trajectory will not be uncontrolled due to the space being too large, nor will the normal floating and separation of the bubbles be affected due to the space being too small, thereby ensuring the smoke filtering effect and the smoothness of the user experience.

[0049] Similarly, when the outer diameter D2 of the smoke guide pipe 142 is 8 mm, the inner diameter D15 of the liquid level separation cover 150 is 12-20 mm. The design of this annular space allows the sound waves generated by the bubble burst to form a directional reflection in the cylindrical space. Since the space size is moderate, the sound will not be weakened due to excessive dispersion of the sound wave energy due to the space being too large, nor will the sound generation be affected due to the space being too small to restrict the movement of bubbles. Therefore, a clear and loud "gurgling" sound can be produced when the bubbles burst.

[0050] In some embodiments, reference Figure 4, the first air outlet 131 and the second air inlet 143 are arranged on the outer surface of the top of the water tank 100, and a rotatable sealing cover 200 is installed on the outer surface, and the sealing cover 200 is provided with the first guide hole 210 and the second guide hole 220 corresponding to the position 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 make the first guide hole 210 and the second guide hole 220 accurately aligned with the first air outlet 131 and the second air inlet 143, and the air flow channel is opened at this time, which is convenient for use; after use, the sealing cover 200 is rotated again to make the two groups of holes staggered, and the air flow channel is closed, so as to achieve a sealing effect. Not only is it easy to operate, but also the sealing effect is reliable, which can effectively prevent the leakage of liquid during carrying, and also avoid the entry of external dust when not in use, thereby improving the safety and portability of the portable hookah. When the sealing cover 200 is in a closed state, even if the hookah device is overturned, the liquid will not leak out from these channels.

[0051] Further, refer to Figure 4 , a first fixing portion 230 is provided on the sealing cover 200, which is connected with the second fixing portion 240 on the top of the water tank 100, so that the sealing cover 200 can stably rotate around the fixed axis. The first guide hole 210 and the second guide hole 220 are distributed in a circle along the axis of the first fixing portion 230 on the sealing cover 200, so that the channel can move in a circle as the sealing cover 200 rotates. For example, when the user needs to use a portable hookah, the sealing cover 200 is rotated, and the first guide hole 210 and the second guide hole 220 will move along a circular trajectory to a position that completely overlaps with the first air outlet 131 and the second air inlet 143, and the air flow channel is fully opened at this time; when sealing is required, the sealing cover 200 only needs to be rotated in the opposite direction, and the two sets of channels will be staggered 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 accuracy of the rotation process. At the same time, the circularly distributed hole design makes the switch action smoother and can accurately control the opening angle, which ensures both smoothness during use and sealing when closed.

[0052] In some embodiments, the first fixing part 230 and the second fixing part 240 can be specifically implemented in the form of a convex shaft and a groove. For example, the first fixing part 230 can be a cylindrical convex shaft provided at the center of the sealing cover 200, and the bottom of the convex shaft can be designed as a slightly enlarged step structure, while the second fixing part 240 is a circular groove provided at the corresponding position on the top of the water tank 100, and there is a circle of card slots inside the groove for accommodating the steps at the bottom of the convex shaft, so that when the convex shaft is inserted into the groove, the step structure will be stuck in the card slot, forming a rotatable but not easy to fall off connection. Another implementation method is that the first fixing part 230 can be designed as a hollow sleeve structure, and the second fixing part 240 is a matching fixing column, and the two are fixed by interference fit or snap-fit, just like the lid rotation structure of a thermos cup. This design can ensure that the sealing cover 200 rotates stably and will not accidentally fall off during use, and is easy to disassemble and clean, ensuring the convenience and safety of the portable hookah during use and maintenance.

[0053] The above is a specific description of the preferred implementation of the present invention, but the invention is not limited to the embodiments. Those skilled in the art can make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
