Technical Field
[0001] This utility model relates to the technical field of hookah smoking utensils, specifically to a hookah. Background Technology
[0002] Hookah is a tobacco substitute popular among some ethnic minorities in my country and in the Middle East. It uses special hookah tobacco that is heated to produce smoke, which is then filtered through water before inhalation. A hookah is the device used for smoking hookah. Existing hookahs generally include a pipe, a straw, and a water bottle. The pipe has a fixed outlet, and various parts with different outlet positions can be fitted to the pipe, allowing the device to be used by multiple consumers at once. A typical hookah usually includes a bowl, tray, pipe, exhaust pipe, and bottle. A soft smoking hose is connected to the exhaust pipe, and a mouthpiece is attached to the end of the hose for the user to inhale. Because the smoking device is always open, dust or foreign objects can easily enter, and liquid or foreign objects from the water bottle can easily enter the device due to misalignment or other reasons, causing blockages and, in severe cases, accidental inhalation. Some manufacturers use dust covers to seal the smoking opening, which can solve the problem of dust entering from the outside, but it does not solve the problem of internal contaminants, and the dust covers are easily lost. Furthermore, the current hookahs can only switch modes electronically, and cannot substantially change the internal passages, especially the exhaust mode, as simply reversing the intake and exhaust cannot completely remove the remaining smoke. Summary of the Invention
[0003] The purpose of this invention is to provide a smoke extraction device for a hookah with a stable structure and smooth mode switching.
[0004] To solve the above-mentioned technical problems, this utility model adopts the following technical solution: a smoke extraction and exhaust device for a hookah, the hookah comprising a body, a smoke outlet device for burning or heating tobacco to generate smoke, a water tank for filtering smoke, a smoke inlet channel connecting the smoke outlet device and the water tank, and a smoke extraction and exhaust device for exhausting filtered smoke or residual smoke to a mouthpiece. The surface of the body has at least two mouthpieces, which are a main mouthpiece and at least one auxiliary mouthpiece. The smoke extraction and exhaust device includes a mouthpiece assembly installed at the main mouthpiece position on the body, a sealing element made of elastic material and fitted into the body, and a third smoke extraction channel connecting the sealing element and the water tank. The mouthpiece assembly is rotatably installed within the sealing element with a limited angle and extends out of the main mouthpiece. The sealing element has... The first smoking channel is connected to the third smoking channel, and the assembly cavity is for inserting the mouthpiece assembly. The mouthpiece assembly includes a mouthpiece body inserted into the assembly cavity with the mouthpiece opening extending out of the smoking port, and an angle limiter sleeved on the mouthpiece body. The mouthpiece body has an independent second smoking channel and an air inlet. One end of the second smoking channel is connected to the main smoking port, and the other end forms an internal interface on the surface of the mouthpiece body that can be connected to the end of the first smoking channel in the sealing part. Thus, the third smoking channel, the first smoking channel, and the second smoking channel form a smoking channel corresponding to the main smoking port. One end of the air inlet is the main smoking port, and the other end is connected to the smoke inlet channel. The mouthpiece body can rotate around the axis with a limited angle in the assembly cavity through the angle limiter, thereby realizing the opening and closing switching of the main smoking port to the air inlet channel and the smoking channel.
[0005] As an improvement: the mouthpiece body rotates within the assembly cavity at a limited angle via an angle limiter and has an open position, a closed position, and a smoke exhaust position; in the open position, the inner interface of the second smoking channel is connected to the inner end of the first smoking channel, and the smoking channel from the third smoking channel, the first smoking channel, the second smoking channel to the main smoke outlet is connected and opened; in the closed position, the inner interface of the second smoking channel is closed by the sealing surface of the sealing component assembly cavity, and the smoking channel is closed; in the smoke exhaust position, the inner interface of the air inlet is connected to the smoke inlet channel.
[0006] As an improvement: the angle limiter is connected to an actuator pin, the seal is provided with a socket for the actuator pin to be fixedly engaged, and the outer periphery of the mouthpiece body is also provided with elastic positioning devices corresponding to the open position, the closed position, and the smoke exhaust position, so that the mouthpiece body can be locked and unlocked in the open position, the closed position, and the smoke exhaust position.
[0007] As an improvement, the elastic positioning device is a structure in which an elastic pin and a recess cooperate.
[0008] As an improvement: a smoke guide hole is provided on the mouthpiece body, coaxial with the inner interface, penetrating the mouthpiece body vertically. In the open position, the smoke guide hole is connected vertically to connect the smoke outlet device and the smoke inlet channel. The smoke outlet device is the smoke inlet of the smoke inlet channel. In the closed position, the smoke guide hole is closed by the sealing surface of the sealing component assembly cavity, sealing the smoke inlet channel. In the exhaust position, the smoke guide hole is closed by the sealing surface of the sealing component assembly cavity, and the inner interface of the air inlet channel is connected to the smoke inlet channel. The air inlet channel is the only inlet connecting the smoke inlet channel to the outside, that is, the main smoke outlet is the air blowing inlet of the smoke intake and exhaust device in the exhaust position.
[0009] The beneficial effects of this utility model are as follows: This utility model achieves the opening and closing switching of the main smoke inlet to the air intake and smoking channel through a sealing element and a mouthpiece assembly. It only requires rotation, making operation simple. Because the mouthpiece assembly has an internally sealed design, and this internal seal is located at the connection point with the sealing element, it is an external seal for the mouthpiece body. After sealing, liquid from the water tank cannot enter the mouthpiece body. Simultaneously, the sealing element is a one-piece molded silicone seal with high precision, a tight and stable fit with the mouthpiece body, low cost, and multiple functions. The sealing element plays a crucial sealing role, eliminating splicing risks, ensuring a tight seal, fewer parts, low cost, and excellent expandability. One sealing element can be configured with multiple mouthpiece assemblies, offering strong compatibility. After connecting the smoke guide tube to this smoking device, the entire smoke duct and even the entire hookah are leak-proof. Furthermore, the smoke extraction and exhaust device of this embodiment is also compatible with exhaust modes. The entire smoke extraction and exhaust device has a compact structure, and mode correspondence and switching are very convenient, making operation simple.

[0016] like Figure 1 , Figure 2 , Figure 3 , Figure 4, Figure 5 As shown, this utility model discloses an embodiment of the smoke extraction and exhaust device for a hookah. The hookah includes a body 3, a smoke outlet device for burning or heating tobacco to generate smoke, a water tank 1 for filtering smoke, a smoke inlet channel 6 connecting the smoke outlet device and the water tank 1, and a smoke extraction and exhaust device for expelling filtered smoke or residual smoke to the mouthpiece. The surface of the body has at least two mouthpieces; in this embodiment, there are two mouthpieces, namely a main mouthpiece 81 and a secondary mouthpiece 82. The smoke inlet channel 6 is provided inside the body 3, and the inlet of the smoke inlet channel 6 is located at the bottom of the smoke chamber 31 connected to the hookah cup 5. The smoke inlet channel 6 passes through... The connector extends into the water tank 1. The smoke extraction device includes a mouthpiece assembly 2 installed at the main mouthpiece opening of the pot body 3, a sealing element 4 made of elastic material and assembled into the pot body 3, and a third smoke extraction channel connecting the sealing element 4 and the water tank 1. The mouthpiece assembly 2 is rotatably installed in the sealing element 4 with a limited angle and extends out of the main smoke opening. The sealing element 4 has a first smoke extraction channel 41 and a fourth smoke extraction channel 42 that communicate with the third smoke extraction channel, and an assembly cavity for inserting the mouthpiece assembly 2. The first smoke extraction channel corresponds to the main smoke opening, and the fourth smoke extraction channel corresponds to the auxiliary smoke opening. The cigarette holder assembly includes a cigarette holder body 21 inserted into the assembly cavity with its mouthpiece extending beyond the smoking opening, and an angle limiter 22 sleeved on the cigarette holder body 21. The cigarette holder body 21 has an independent second smoking channel 23 and an air inlet 25 at the main smoking opening position. One end of the air inlet 25 is the main smoking opening, and the other end connects to the smoking inlet channel 6. One end of the second smoking channel 23 connects to the main smoking opening, and the other end forms an internal interface 231 on the surface of the cigarette holder body 21 that can connect with the end of the first smoking channel within the sealing member 4. Thus, the third smoking channel 5, the first smoking channel 41, and the second smoking channel 23 form a smoking channel corresponding to the main smoking opening. The cigarette holder body 21 also has a fifth smoking channel 26 at the auxiliary smoking opening position, which, along with the third smoking channel 5, the fourth smoking channel 42, and the fifth smoking channel 26, forms a smoking channel corresponding to the auxiliary smoking opening. The mouthpiece body 21, via an angle limiter 22, can rotate around an axis within the assembly cavity at a limited angle, thereby enabling the main smoke outlet to switch between the air intake and the smoking channel. Because the seal 4 is made of one-piece molded elastic silicone, the sealing surface provides a certain degree of adjustment damping during adjustment, resulting in excellent adjustment feel. It is also stepless, allowing for easy positioning. The actuator pin 221 secures the mouthpiece body 21 to the horizontal plane within the seal, ensuring a stable connection. The one-piece molded seal provides sealing and independent protection for multi-channel configurations.
[0017] A smoke guide hole 24, coaxial with the inner interface 231, is provided on the mouthpiece body 21, penetrating vertically through the mouthpiece body. The mouthpiece body 21 rotates within the assembly cavity with a limited angle via an angle limiter 22, and has three rotational positions: open, closed, and exhaust. In the open position, the three holes of the mouthpiece body 21 correspond to the sealing element, i.e., the inner interface 231 of the second smoke channel 23 is connected to the inner end of the first smoke channel 41. The smoke channel from the third smoke channel 5, the first smoke channel, and the second smoke channel 23 to the main smoke outlet is connected and opened. The smoke channel corresponding to the auxiliary smoke outlet, composed of the third smoke channel 5, the fourth smoke channel 42, and the fifth smoke channel 26, is also connected and opened, i.e., the smoke channels are fully open. The smoke guide hole 24 is vertically connected to connect the bottom of the smoke chamber 31 to the smoke inlet channel 6, and the bottom of the smoke chamber 31 is the smoke inlet of the smoke inlet channel 6. In the closed position, the mouthpiece body 21 has no corresponding sealing hole. The inner interfaces of the second smoke channel 23 and the fifth smoke channel 26 are sealed by the sealing surface of the assembly cavity of the sealing component 4. The smoke channel is closed, and the smoke guide hole 24 is sealed by the sealing surface of the assembly cavity of the sealing component 4, thus sealing the smoke inlet channel. The smoke guide hole 24 is sealed by the sealing surface of the assembly cavity of the sealing component 4, thus sealing the smoke guide tube. This allows the entire flue to be opened and closed with a single turn. For the water tank, this closes the two-way passage, locks the liquid inside, and prevents the whole machine from leaking water. At the smoke exhaust position, the two holes of the mouthpiece body 21 correspond to the sealing element. The smoke guide hole 24 is closed by the sealing surface of the assembly cavity of the sealing element 4. The inner interface of the air intake channel is connected to the smoke intake channel 6. The air intake channel 2 is the only inlet connecting the smoke intake channel 6 to the outside. That is, the main smoke outlet is the air blowing inlet of the smoke exhaust device at the smoke exhaust position, which ensures the formation and strength of the water surface impact. The first inner interface 232 corresponding to the fifth smoke exhaust channel 26 is connected to the third smoke exhaust channel 5. The smoke exhaust channel corresponding to the auxiliary smoke outlet is connected and opened by the third smoke exhaust channel 5, the fourth smoke exhaust channel 42 and the fifth smoke exhaust channel 26, forming the exhaust channel.
[0018] In this embodiment, for ease of use, a smoother operation, and accurate positioning, an actuator pin 221 is connected to the angle limiter. The sealing element 4 has a socket 43 for the actuator pin 221 to be fixedly engaged. The outer periphery of the mouthpiece body is also equipped with elastic positioning devices 7 corresponding to the open, closed, and exhaust positions, respectively, allowing the mouthpiece body 21 to be locked and unlocked in these positions. The elastic positioning device is a structure of elastic pin and recess engagement. This elastic positioning device is easy to implement, requires less space, and is more suitable for rotational positioning. Alternatively, a bearing with a stop mechanism can also be used.
[0019] Although the present invention has been disclosed above with specific embodiments, it is not intended to limit the present invention. Any person skilled in the art may make some modifications and refinements without departing from the spirit and scope of the present invention. Therefore, the scope of protection of the present invention shall be determined by the scope of the appended claims.
