Description

Technical Field

[0001] This application relates to the field of smoking accessories technology, and in particular to a dual-form pipe. Background Technology

[0002] Currently, pipes on the market are mainly divided into two categories: regular pipes and hookah pipes. Regular pipes have a relatively simple structure, usually consisting of a pipe body and a mouthpiece. After the tobacco burns in the combustion chamber, the smoke is directly inhaled by the user through the mouthpiece. However, the smoke from this type of pipe is unfiltered and may contain harmful substances such as tar and nicotine, as well as particulate impurities. Long-term use may have potential health effects.

[0003] Hookah pipes reduce impurities in the smoke through a water filtration mechanism. The principle is that as the smoke passes through the water container, some harmful substances are absorbed by the water, thus improving the user experience. However, traditional hookah pipes have significant drawbacks: they require a dedicated water filter container, which is bulky and structurally fixed, making them inconvenient to carry, especially in outdoor settings; dedicated accessories (such as water bottles and straws) must be purchased separately, increasing usage costs; and existing hookah devices are mostly single-form designs, incompatible with regular pipes, requiring users to purchase two separate devices, leading to resource waste and limited usage scenarios. Summary of the Invention

[0004] In view of this, this application provides a dual-form pipe to solve the problems of insufficient smoke filtration in ordinary pipes and the inconvenience and high cost of hookah pipes.

[0005] This application provides a dual-form pipe, the dual-form pipe comprising:

[0006] The pipe body has a tobacco combustion chamber at the top and a detachable bottom cover at the bottom. The bottom of the pipe body has an annular threaded connection, and the detachable bottom cover is installed on the annular threaded connection by threaded engagement.

[0007] A mouthpiece, connected to the side of the pipe body, connected to the tobacco combustion chamber, and used for inhaling smoke; and

[0008] The conversion kit includes a threaded bottom cover, a water pipe, and a sealing ring. The threaded bottom cover is adapted to the annular threaded connection at the bottom of the pipe body. The inner side of the threaded bottom cover is also provided with an annular interface. The water pipe is detachably connected to the annular interface. The inner side of the threaded bottom cover is provided with an annular mounting groove. The sealing ring is embedded in the annular mounting groove and surrounds the water pipe.

[0009] The dual-form pipe has both a regular pipe mode and a hookah mode.

[0010] When the dual-mode pipe is in the ordinary pipe mode, the detachable bottom cover is tightened and sealed to the threaded interface at the bottom of the pipe body, so that the tobacco combustion chamber forms an independent combustion space and the smoke can be directly inhaled through the mouthpiece.

[0011] When the dual-mode pipe is in hookah mode, by removing the detachable bottom cover, the water pipe is connected to the pipe body through the threaded bottom cover. One end of the water pipe is inserted into the bottom of the pipe body, and the other end of the water pipe is inserted into a container filled with filtered water, so that the smoke can be filtered by water and then inhaled through the mouthpiece.

[0012] The mouthpiece includes a mouthpiece end, a middle adjustment section, and a pipe connecting section. One end of the mouthpiece end is provided with a concave arc-shaped bite part, and the other end of the mouthpiece end is detachably connected to one end of the middle adjustment section. The other end of the middle adjustment section is detachably connected to one end of the pipe connecting section, and the length of the middle adjustment section is interchangeable and adjustable. The other end of the pipe connecting section is connected to the pipe body.

[0013] The water pipe is composed of a first water pipe section, a second water pipe section, and a third water pipe section connected together. The first water pipe section, the second water pipe section, and the third water pipe section are detachably connected to each other. By increasing or decreasing the number of connected water pipe sections or adjusting the connection position, the overall length of the water pipe can be adjusted.

[0014] The first water pipe section, the second water pipe section, and the third water pipe section are all provided with threaded connectors at both ends, and adjacent water pipe sections can be detachably screwed together by the threaded connectors.

[0015] The pipe body is also provided with a double-layer heat insulation wall, including an inner stainless steel liner and an outer ceramic fiber heat insulation layer. The stainless steel liner forms the inner wall of the tobacco combustion chamber and the main airflow channel. The ceramic fiber heat insulation layer is tightly attached to the outer side of the stainless steel liner, and the two are fixedly connected by a high-temperature resistant adhesive.

[0016] The pipe body also has a filter groove, which is located at the connection channel between the tobacco combustion chamber and the mouthpiece. The filter groove is used to install activated carbon filter or ceramic filter, and the inner wall of the filter groove is provided with anti-slip texture.

[0017] The outer wall of the tobacco combustion chamber is provided with a spiral ventilation regulating ring. The spiral ventilation regulating ring is screwed onto the outside of the tobacco combustion chamber and can rotate around the axis of the tobacco combustion chamber. Multiple ventilation holes are evenly distributed on the ring body. The air intake of the tobacco combustion chamber can be controlled by controlling the rotation angle of the spiral ventilation regulating ring.

[0018] The mouthpiece has a built-in rotation adjustment mechanism, which includes a spiral guide vane connected to the inner wall of the middle section of the mouthpiece. The air intake of the mouthpiece can be controlled by controlling the rotation angle of the rotation adjustment mechanism.

[0019] The water pipe has a positioning and fixing structure at the end near the water filter container to fix the water filter container. The positioning and fixing structure includes an elastic retaining ring and an anti-slip support. The elastic retaining ring is fitted on the outside of the end of the water pipe and can slide along the water pipe axis and be fixed by a limiting boss. The anti-slip support is an annular silicone pad that is evenly distributed on the outside of the elastic retaining ring and contacts the water filter container.

[0020] The dual-mode hookah provided in this application allows for quick switching between a regular hookah mode and a hookah mode. The main body of the hookah, the detachable bottom cap, and the conversion kit all utilize threaded connections, ensuring stable mechanical fit and supporting repeated assembly and disassembly to reduce wear and tear and extend component lifespan. Furthermore, the overall structure can be disassembled into independent parts, significantly reducing storage volume compared to traditional hookah devices, making it easy to carry. Additionally, the water hose of the conversion kit connects to common beverage bottles such as mineral water or cola bottles, directly using them as filter containers for hookah mode, eliminating the need to purchase dedicated water filter accessories, thus reducing consumable costs and enhancing the product's economic and environmental value. The dual-mode hookah allows for seamless switching between the two modes without additional tools, effectively expanding the product's application range and making it suitable for various scenarios such as home and outdoor use, improving the product's flexibility and convenience.

The appearance of this phrase in various places throughout the specification does not necessarily refer to the same embodiment, nor is it a separate or alternative embodiment mutually exclusive with other embodiments. It will be explicitly and implicitly understood by those skilled in the art that the embodiments described herein can be combined with other embodiments.

[0036] Please see Figure 1 , Figure 2 and Figure 3 , Figure 1 This is a schematic cross-sectional view of a dual-form pipe provided in one embodiment of this application. Figure 2 This is a side view of a dual-form pipe according to an embodiment of this application. Figure 3 This is a schematic diagram of the structure of a dual-form pipe provided in one embodiment of this application. This application provides a dual-form pipe 1, which includes a pipe body 10, a mouthpiece 20, and a conversion kit 30. The top of the pipe body 10 is provided with a tobacco combustion chamber 11, and the bottom surface of the pipe body 10 is provided with a removable bottom cover 12. The bottom of the pipe body 10 is provided with an annular threaded connection portion 13, and the removable bottom cover 12 is threadedly installed onto the annular threaded connection portion 13. The mouthpiece 20 is connected to the side of the pipe body 10, communicates with the tobacco combustion chamber 11, and is used to inhale smoke. The conversion kit 30 includes a threaded bottom cover 31, a water pipe 32, and a sealing ring 33. The threaded bottom cover 31 is adapted to the annular threaded connection part 13 at the bottom of the pipe body 10. The inner side of the threaded bottom cover 31 is also provided with an annular interface. The water pipe 32 is detachably connected to the annular interface. The inner side of the threaded bottom cover 31 is provided with an annular mounting groove. The sealing ring 33 is embedded in the annular mounting groove and surrounds the water pipe 32.

[0037] Optionally, the sealing ring 33 is fitted into the annular mounting groove to form a sealing elastic structure, which enhances the sealing performance when the water pipe 32 is inserted. Preferably, the sealing ring 33 is a silicone sealing ring 33, which can maintain good elasticity during long-term use.

[0038] Optionally, the removable bottom cover 12 has internal threads and can be adapted to connect with the annular threaded connection part 13 at the bottom of the pipe body 10. The threaded bottom cover 31 also has threads and is adapted to the annular threaded connection part 13 at the bottom of the pipe body 10 to ensure a tight connection and facilitate disassembly. In this embodiment, the connection and adjustment between various components are achieved through threaded connections. Threaded connections have good stability and repeatability; components can be repeatedly disassembled and reassembled without damage, ensuring the product's service life and durability.

[0039] The dual-form pipe 1 provided in this embodiment has a regular pipe mode and a hookah mode. When the dual-form pipe 1 is in regular pipe mode, the removable bottom cover 12 is tightened and sealed to the threaded interface at the bottom of the pipe body 10, so that the tobacco combustion chamber 11 forms an independent combustion space, and the smoke can be directly inhaled through the mouthpiece 20. When the dual-form pipe 1 is in hookah mode, the removable bottom cover 12 is removed, and the water pipe 32 is connected to the pipe body 10 through the threaded bottom cover 31. One end of the water pipe 32 is inserted into the bottom of the pipe body 10, and the other end of the water pipe 32 is inserted into a container containing filtered water, so that the smoke is filtered by water and then inhaled through the mouthpiece 20.

[0040] Specifically, when the dual-form pipe 1 is in the ordinary pipe mode, the threaded bottom cover 31 is fully tightened to the threaded interface at the bottom of the pipe body 10 to ensure that there are no gaps at the threaded interface. The tobacco is then loaded into the combustion chamber and lit. The user can directly inhale the smoke through the mouthpiece 20.

[0041] Furthermore, when the dual-mode pipe 1 is in hookah mode, unscrew the detachable bottom cover 12, insert the water pipe 32 into the bottom of the pipe, and insert the other end of the water pipe 32 into the mouth of a beverage bottle to achieve the function of water filtering smoke.

[0042] Preferably, the dual-form pipe 1 provided in this embodiment can use common waste beverage bottles in daily life as filter containers in hookah form, such as mineral water bottles, cola bottles, etc., eliminating the need to purchase dedicated water filter containers, reducing the use of dedicated accessories and consumables, and improving the economy and applicability of the dual-form pipe 1.

[0043] In summary, the dual-form pipe 1 provided in this application can quickly switch between a regular pipe mode and a hookah mode. The pipe body 10, detachable bottom cover 12, and conversion kit 30 are all connected by threads, providing stable mechanical fit and supporting repeated disassembly and assembly, thereby reducing wear and tear and extending component lifespan. Furthermore, the overall structure can be disassembled into independent parts, significantly reducing storage volume compared to traditional hookah devices, making it easy to carry. Additionally, the water pipe 32 of the conversion kit 30 can be connected to common beverage bottles such as mineral water bottles and cola bottles, directly using them as filter containers for hookah mode, eliminating the need to purchase dedicated water filter accessories, thus reducing consumable costs and improving the product's economic and environmental value. The dual-form pipe 1 allows for switching between the two modes without additional tools, effectively expanding the product's application range and making it suitable for various scenarios such as home and outdoor use, enhancing the product's flexibility and convenience.

[0044] Please see Figure 4 , Figure 4 This is a top view schematic diagram of a dual-form pipe provided in an embodiment of this application. The mouthpiece 20 includes a mouthpiece end 21, a middle adjustment section 22, and a pipe connecting section 23. One end of the mouthpiece end 21 is provided with a concave arc-shaped bite portion. The other end of the mouthpiece end 21 is detachably connected to one end of the middle adjustment section 22. The other end of the middle adjustment section 22 is detachably connected to one end of the pipe connecting section 23, and the length of the middle adjustment section 22 is interchangeable and adjustable. The other end of the pipe connecting section 23 is connected to the pipe body 10.

[0045] In this embodiment, the mouthpiece 20 adopts a three-section split structure, allowing it to be combined or disassembled according to different usage scenarios, thereby changing its length and flavor. During the use of the dual-form pipe 1, after lighting the tobacco, the user directly inhales the smoke through the three-section mouthpiece 20. Furthermore, the three-section structure of the mouthpiece 20 can be combined according to personal preference, adjusting its length and angle for a more comfortable user experience.

[0046] Please see Figure 5 , Figure 5 This is a side view of a dual-form pipe according to another embodiment of this application. The water pipe 32 is formed by connecting a first water pipe segment 331, a second water pipe segment 332, and a third water pipe segment 333. The first water pipe segment 331, the second water pipe segment 332, and the third water pipe segment 333 are detachably connected to each other. By increasing or decreasing the number of connected water pipe segments 32 or adjusting the connection position, the overall length of the water pipe 32 can be adjusted.

[0047] Optionally, the water pipe 32 is composed of three hollow tubular components, each with an external thread at its end, and adjacent sections are screwed together using an internal thread connector. The total length of the water pipe 32 can be adjusted or shortened according to the height of different beverage bottles to achieve adaptability to various beverage bottles. Furthermore, when portable, the spout 20 and water pipe 32 can be detached, significantly reducing storage volume and making it convenient for users to carry, meeting the needs of outdoor use and other scenarios.

[0048] Specifically, when the dual-form pipe 1 is used in hookah mode, the first water pipe section 331, the second water pipe section 332, and the third water pipe section 333 are combined or shortened according to the height of the beverage bottle, and connected by threads to form a water pipe 32 of appropriate length. One end of the combined water pipe 32 is inserted into the bottom of the pipe, ensuring a tight connection, and the other end is inserted into the mouth of a beverage bottle that has been filled with water. At this time, the tobacco in the combustion chamber is lit, and the smoke is filtered by the water in the beverage bottle before entering the mouthpiece 20. The filtered smoke is then inhaled by the user through the water pipe 32 and the mouthpiece 20. The three-section water pipe 32 design can flexibly adapt to beverage bottles of different heights, such as common mineral water bottles and cola bottles, without the need for additional special containers, thus improving the product's versatility and convenience.

[0049] Please see Figure 6 , Figure 6 This is a cross-sectional structural diagram of a dual-form pipe provided in another embodiment of this application. The pipe body 10 is also provided with a double-layer heat insulation wall, including an inner stainless steel inner liner 15 and an outer ceramic fiber heat insulation layer 16. The stainless steel inner liner 15 forms the inner wall of the tobacco combustion chamber 11 and the main airflow channel. The ceramic fiber heat insulation layer 16 is tightly attached to the outside of the stainless steel inner liner 15, and the two are fixedly connected by a high-temperature resistant adhesive.

[0050] Optionally, the thickness of the ceramic fiber insulation layer 16 ranges from 0.7 mm to 0.9 mm.

[0051] In this embodiment, the stainless steel inner liner 15 forms the inner wall of the tobacco combustion chamber 11 and the airflow channel, effectively blocking the direct erosion of the ceramic fiber insulation layer 16 by high temperatures. Simultaneously, the ceramic fiber insulation layer 16 prevents external heat from being conducted to the inner liner, reducing structural damage caused by thermal expansion and contraction, and extending the overall lifespan of the pipe. Furthermore, the ceramic fiber insulation layer 16 possesses excellent heat insulation performance, significantly reducing the outer surface temperature of the pipe body 10 compared to traditional single-layer structures, thereby preventing burns when the user holds the pipe and improving its safety. In addition, the double-layer insulation effectively reduces heat loss from the tobacco combustion chamber 11, maintaining a stable combustion temperature for the tobacco within the chamber, ensuring consistent smoke concentration and flavor, and enhancing the user experience.

[0052] Please see Figure 7 , Figure 7 This is a cross-sectional structural diagram of a dual-form pipe provided in another embodiment of this application. The pipe body 10 also has a filter groove 14, which is disposed at the connection channel between the tobacco combustion chamber 11 and the mouthpiece 20. The filter groove 14 is used to install activated carbon filter or ceramic filter, and the inner wall of the filter groove 14 is provided with anti-slip texture.

[0053] In this embodiment, the filter slot 14 of the pipe body 10 can be fitted with an activated carbon filter or a ceramic filter. The activated carbon filter, with its rich porous structure, can effectively adsorb harmful components such as tar and nicotine in the smoke. The ceramic filter, through physical filtration and microporous adsorption, filters particulate impurities in the smoke, improving the purity of the smoke while reducing harm to the human body. Furthermore, in normal pipe mode, the filter can function independently. When switching to hookah mode, the filter and the water in the beverage bottle form a dual filtration structure, further purifying the smoke.

[0054] Optionally, the anti-slip texture and the inner wall of the filter groove 14 formed by the pipe body 10 are integrally formed. In this embodiment, the anti-slip texture provided on the inner wall of the filter groove 14 can increase the friction between the filter and the groove wall, ensuring that the filter is stably installed during use. Even when the pipe is shaking or tilted, it can prevent the filter from shifting or falling off, ensuring the stability and continuity of the filtration effect.

[0055] Please see Figure 8 , Figure 8 This is a cross-sectional structural diagram of a dual-form pipe provided in another embodiment of this application. A spiral ventilation regulating ring 17 is provided on the outer wall of the tobacco combustion chamber 11. The spiral ventilation regulating ring 17 is screwed onto the outside of the tobacco combustion chamber 11 and can rotate around the axis of the tobacco combustion chamber 11. Multiple ventilation holes 171 are evenly distributed on the ring body of the spiral ventilation regulating ring 17. The air intake of the tobacco combustion chamber 11 can be controlled by controlling the rotation angle of the spiral ventilation regulating ring 17.

[0056] Optionally, the rotation angle range of the spiral ventilation regulating ring 17 is 0°-90°. When the spiral ventilation regulating ring 17 is in the initial position of 0°, the multiple ventilation holes 171 are completely misaligned with the air inlet of the tobacco combustion chamber 11, and the air intake is 0. When the spiral ventilation regulating ring 17 rotates to 90°, the multiple ventilation holes 171 are completely aligned with the air inlet of the tobacco combustion chamber 11, and the total air intake area reaches its maximum.

[0057] Optionally, the spiral ventilation adjustment ring 17 is provided with an angle scale mark on the outside, corresponding to four positioning positions: 0°, 30°, 60°, and 90°. Each position is provided with a limiting protrusion that engages with the limiting groove on the outer wall of the tobacco combustion chamber 11, ensuring clear position feedback and stable positioning performance during rotation adjustment.

[0058] In this embodiment, the air intake of the tobacco combustion chamber 11 can be adjusted in real time by controlling the rotation angle of the spiral ventilation adjustment ring 17. Users can precisely control the air intake by rotating the spiral ventilation adjustment ring 17 according to their individual smoking habits and tobacco characteristics. For example, when a quick smoke is desired, increasing the air intake accelerates tobacco combustion; when a slower, more enjoyable experience is desired, decreasing the air intake reduces the combustion rate, meeting personalized usage needs. Furthermore, proper air intake control allows for longer tobacco combustion, reducing the frequency of adding tobacco, which is particularly suitable for outdoor settings where it is inconvenient to replenish tobacco frequently, thus improving ease of use. Precise air intake control also ensures more complete and even tobacco combustion, preventing incomplete combustion and off-flavors caused by insufficient air intake, or high-temperature burnt flavors caused by excessive air intake, thereby improving the purity and taste of the smoke. In addition, the rotation operation of the spiral ventilation adjustment ring 17 is simple and intuitive, and standardized control can be achieved through preset angle limits or scale markings, achieving ideal air intake effects without complex operations.

[0059] Please refer to it again. Figure 8 The mouthpiece 20 has a built-in rotation adjustment mechanism 24, which includes a spiral guide vane 241. The spiral guide vane 241 is connected to the inner wall of the middle section of the mouthpiece 20. By controlling the rotation angle of the rotation adjustment mechanism 24, the air intake of the smoke in the mouthpiece 20 can be controlled.

[0060] Optionally, the rotation adjustment mechanism 24 further includes copper heat dissipation fins and a positioning bearing. The spiral guide vane 241 is rotatably connected to the inner wall of the middle section of the nozzle 20 through the positioning bearing, and can achieve three angle positioning at 0°, 90° and 180° around the axis of the nozzle 20.

[0061] Optionally, the axial rotation adjustment mechanism 24 can switch between three airflow modes, including a direct-flow mode, a diffusion mode, and a cooling mode. Specifically, when the axial rotation adjustment mechanism 24 is in the direct-flow mode, the spiral guide vane 241 is positioned at 0°, and the closed direct-flow airflow channel formed by the spiral guide vane 241 has a smooth inner wall, achieving gentle smoke inhalation. When the axial rotation adjustment mechanism 24 is in the diffusion mode, the spiral guide vane 241 is positioned at 90°, and the spiral guide vane 241 is extended to a horizontal state, forming a diffusion airflow channel. The cross-sectional area of ​​the channel is larger than that in the direct-flow mode, suitable for rapid smoke inhalation scenarios. When the axial rotation adjustment mechanism 24 is in the cooling mode, the spiral guide vane 241 is positioned at 180°, and the spiral guide vane 241 drives the copper heat dissipation fins to rotate perpendicular to the airflow direction. The heat dissipation fins are distributed in a ring array, increasing the total heat dissipation surface area compared to the traditional mouthpiece 20, thereby reducing the smoke temperature.

[0062] In this embodiment, the user can quickly switch between different air intake modes by rotating the rotary adjustment mechanism 24. When a large amount of vapor is needed, the air intake is increased to obtain a rich vapor experience; when a smoother taste is desired, the air intake is reduced to make the vapor more delicate, meeting diverse usage needs. Furthermore, precise control of the air intake can avoid the throat-choking sensation caused by excessively rapid or dense vapor, while also preventing the problem of difficult inhalation due to insufficient air intake, thus optimizing comfort during use.

[0063] Please see Figure 9 , Figure 9 This is a schematic diagram of the structure of a dual-form pipe provided in another embodiment of this application. The water pipe 32 has a positioning and fixing structure 334 near the end of the water filter container for fixing the water filter container. The positioning and fixing structure 334 includes an elastic retaining ring 3341 and an anti-slip support 3342. The elastic retaining ring 3341 is fitted onto the outer side of the end of the water pipe 32, can slide along the axial direction of the water pipe 32, and is fixed by a limiting boss. The anti-slip support 3342 is an annular silicone pad, evenly distributed on the outer side of the elastic retaining ring 3341 and in contact with the water filter container.

[0064] Optionally, the elastic retaining ring 3341 can slide along the axial direction of the water pipe 32 and be fixed by the limiting boss, and its position can be flexibly adjusted according to the thickness of the filtered water container (such as a beverage bottle).

[0065] In this embodiment, the elastic retaining ring 3341 can adapt to beverage bottles of different diameters and shapes (such as cylindrical mineral water bottles and irregularly shaped cola bottles), achieving a stable connection without additional accessories. Meanwhile, the silicone anti-slip support 3342 possesses excellent flexibility, adapting to the curvature of the container surface, greatly enhancing the versatility of the pipe in hookah mode. During use, the user only needs to slide the elastic retaining ring 3341 to the appropriate position and screw it into the water pipe 32 via the limiting boss to complete the installation, requiring no tools and improving ease of use. The anti-slip support 3342 fits tightly against the outer wall of the container, securing it even when shaking or tilting, preventing water spillage or equipment tipping, ensuring safe and reliable use.
