Description

Technical Field

[0001] The present invention relates to the technical field of smoking appliances, and in particular to a water pipe valve and a water pipe that can simultaneously supply multiple people to smoke and blow smoke. Background Art

[0002] Hookah is a tobacco substitute popular in the Middle East. The special hookah tobacco material produces smoke after being heated and is inhaled after being filtered by water. The water pipe is a tool for smoking hookah. Although the existing water pipes can be described as allowing multiple people to smoke simultaneously in terms of function, they can only achieve simultaneous smoking and cannot prevent one person's blowing smoke from affecting the use of others. Blowing smoke is a form of entertainment for smoking hookah and can bring different pleasures to users. The common method for blowing smoke with the existing water pipes is usually as follows: close the smoking channels of other users, and one person blows air into it through a hose. The exhaust valve is opened, and the smoke in the water container is discharged from the exhaust valve, which is not convenient for multiple people to use. Summary of the Invention

[0003] In order to overcome the deficiencies in the prior art, the present invention provides a water pipe valve that can enable multiple people to smoke and blow smoke simultaneously without mutual interference.

[0004] The present invention also provides a water pipe that can enable multiple people to smoke and blow smoke simultaneously without mutual interference and has a compact structure.

[0005] In order to achieve the above object, the present invention adopts the following technical solutions to implement:

[0006] A water pipe valve includes a valve core, and the valve core includes an inhalation channel and a blowing channel. The inhalation channel is provided with a first seal, and the first seal keeps the inhalation channel in a normally closed state;

[0007] The blowing channel includes a blowing section, a seal moving section, and an air outlet section arranged in sequence. The blowing section is connected to the air outlet section through the seal moving section. A first opening is formed at the connection between the seal moving section and the blowing section, and a second opening is formed at the connection between the seal moving section and the air outlet section. The seal moving section is provided with a second seal; under normal conditions, the second seal is located between the first opening and the second opening, so that the blowing section is not communicated with the air outlet section;

[0008] When a certain amount of gas is input into the blowing channel through the blowing section, the second seal moves towards the air outlet section and connects the blowing section and the air outlet section.

[0009] The side of the valve for inhalation and blowing is the acting force side, and the other side is the non-acting force side.

[0010] When inhaling, suction force will act on the first sealing member. As long as the suction force can overcome other forces acting on the first sealing member and enable the first sealing member to open the suction channel, the gas can reach the force side from the non-force side of the valve.

[0011] During blowing, the blown air will enter the blowing channel through the blowing section, and the air pressure on the blowing end side of the second seal will increase. As long as the air pressure on the blowing end side of the second seal can overcome other forces acting on the second seal and make the second seal move toward the air outlet section and finally connect the blowing section and the air outlet section, the blowing channel can be opened and the gas can reach the non-force side from the force side.

[0012] When there is no force, the air intake channel is in a normally closed state due to the first seal; the second seal is located between the first opening and the second opening, so that the blowing section and the air outlet section are not connected, that is, the air blowing channel is in a closed state; the gas cannot reach the non-force side from the force side or from the non-force side to the force side.

[0013] Furthermore, the axis of the blowing section is parallel to or forms an angle with the axis of the sealing element movable section.

[0014] Furthermore, a line connecting two points on the surface of the second seal member that are farthest apart is larger than a maximum width of the second opening, so that the second seal member cannot pass through the second opening, thereby preventing the second seal member from leaving the seal member activity area.

[0015] Furthermore, the seal active section has no other openings except the first opening and the second opening, thereby ensuring that the gas blown into the blowing section goes out from the gas outlet section, while also preventing the second seal from escaping from the seal active area.

[0016] Furthermore, the seal movable section includes a second cylindrical hole section and a second conical hole section, and the second seal is a second sealing ball.

[0017] Furthermore, the air intake passage includes a first conical hole section and a first cylindrical hole section, and the first sealing member is a first sealing ball.

[0018] The conical section design and the sealing ball design are adopted to improve the sealing performance of the air valve of the present invention and facilitate the resetting of the sealing ball.

[0019] Furthermore, the blowing section includes an air cavity, the blowing section is connected to the sealing movable section through the air cavity, one end of the blowing section is connected to the air cavity, one end of the sealing movable section is connected to the air cavity, and the first opening is formed at the connection between the air cavity and the sealing movable section.

[0020] By setting the air cavity, it is easier to blow the second seal, making it easier for the blowing section to communicate with the air outlet section.

[0021] Further, the air outlet section includes a connecting section. The air outlet section communicates with the movable section of the seal through the connecting section, and the second opening is formed at the connection between the connecting section and the movable section of the seal.

[0022] Further, on one side where the air outlet section communicates with the movable section of the seal, a first groove with a first cover is formed, and the second opening is arranged in the first groove. This structure is convenient for processing.

[0023] Further, the second seal makes the movable section of the seal and the air outlet section not communicate under normal conditions.

[0024] Further, a fourth seal is also arranged on the movable section of the seal. The fourth seal cooperates with the second seal to make the movable section of the seal and the air outlet section not communicate under normal conditions.

[0025] When someone inhales forcefully, if the movable section of the seal and the air outlet section communicate under normal conditions, the gas above the second seal will be sucked out by others through the air outlet section, resulting in a decrease in the air pressure above the second seal, thereby causing the second seal to open and connect the blowing section and the air outlet section. Therefore, the movable section of the seal and the air outlet section are made not to communicate under normal conditions.

[0026] Further, a through hole is opened at one end of the movable section of the seal away from the first opening, connecting the upper part of the movable section of the seal to the outside, making it easier to blow the seal.

[0027] Further, the air outlet section and the suction channel share a through hole penetrating the valve core, and the first opening is located below the first seal, which can make the structure more compact.

[0028] Further, the air outlet section and the suction channel share a through hole penetrating the valve core. When a connecting section is provided, the fifth opening is formed at the connection between the connecting section and the suction channel, and the fifth opening is located below the first seal.

[0029] Further, the hookah air valve includes a first connecting piece, and the first connecting piece is used to connect a first external device and the air valve core. A first seal blocking body for preventing the first seal from escaping from the suction channel is arranged on the connection side of the first connecting piece and the air valve core.

[0030] Further, the hookah air valve includes a second connecting piece, and the second connecting piece is used to connect the air valve core and a second external device.

[0031] The size of the cavity of the second connecting piece matches that of the valve core of the air valve. The valve core of the air valve is fixed inside the second connecting piece. One side of the first sealing member blocking body is connected to the second connecting piece on the first connecting piece, and the other end of the first connecting piece is connected to a first external device, and the other end of the second connecting piece is connected to a second external device, realizing the connection between the first external device, the valve core of the air valve and the second external device.

[0032] A hookah includes a tobacco bowl, a charcoal tray, a tobacco rod, a hookah base and a water container connected in sequence from top to bottom. The tobacco rod passes through the hookah base and is placed in the water container. The hookah base is provided with one or more suction and blowing channels. Each suction and blowing channel is provided with an air valve, and the air valve adopts the air valve of the new hookah. The hookah base is provided with an exhaust device, and the exhaust device is provided with an exhaust channel. A third sealing member is arranged in the exhaust channel, and the third sealing member keeps the exhaust channel in a normally closed state; the external force required for the third sealing member to open the exhaust channel is smaller than that for the first sealing member to open the suction channel.

[0033] Water is contained in the water container, and the end of the tobacco rod is immersed in the water; hoses are connected to all the air valves, and a suction nozzle is arranged at the end of the hose for sucking and blowing smoke. Multiple suction and blowing channels are provided for multiple people to smoke simultaneously.

[0034] When smoking, the user inhales through the hose. As long as the suction force can overcome other forces acting on the first sealing member and open the suction channel, the water pressure on the water in the water container is reduced, and the external air pressure presses the burned smoke into the water container. After the smoke passes through the water, it is sucked by the user through the suction channel and the hose.

[0035] When blowing smoke, the user blows through the hose, and the blown air will enter the blowing channel through the blowing section. The air pressure on the blowing end side of the second sealing member will increase. As long as the air pressure on the blowing end side of the second sealing member can overcome other forces acting on the second sealing member and make the second sealing member move towards the air outlet section, finally connecting the blowing section and the air outlet section, the blowing channel can be opened. The gas finally reaches the water container and increases the water pressure on the water in the water container. When the pressure in the water container is greater than the external pressure, the third sealing member opens the exhaust channel, and the excess smoke on the water in the water container is discharged from the exhaust channel. The external force required for the third sealing member to open the exhaust channel is smaller than that for the first sealing member to open the suction channel. Therefore, when the pressure in the water container is greater than the external pressure, the third sealing member is opened, and the first sealing member still closes the suction channel.

[0036] When not puffing on the cigarette, the suction passage is in a normally closed state due to the first seal; since the second seal is located between the first opening and the second opening, that is, the blowing section and the air outlet section are not connected, the blowing passage is closed.

[0037] Further, the smoke exhaust passage includes a third conical hole section and a third cylindrical hole section, and the third seal is a third sealing ball, which improves the sealing performance of the smoke exhaust passage and facilitates the reset of the third sealing ball.

[0038] Further, the smoke exhaust device is integrated on the hookah base, and the smoke exhaust device is provided with a third cover for preventing the third seal from escaping from the smoke exhaust passage.

[0039] Integrating the smoke exhaust device on the hookah base makes the structure of the present invention compact.

[0040] Further, the top of the hookah base is recessed inward to form a second groove, the smoke exhaust passage is arranged at the bottom end of the second groove, a cigarette rod mounting hole is arranged at the central positions of the second groove and the third cover, a cigarette rod matching the size of the cigarette rod mounting hole is arranged through the cigarette rod mounting hole, the cigarette rod is tightly fitted between the cigarette rod mounting hole and the hookah base, a smoke exhaust cavity is formed between the inner wall of the second groove and the outer side wall of the cigarette rod, the third cover matches the smoke exhaust cavity and exactly covers the top of the smoke exhaust cavity, and a smoke outlet hole is opened on the hookah base, and the smoke exhaust cavity communicates with the outside through the smoke outlet hole.

[0041] The smoke outlet hole discharges the smoke coming out of the smoke exhaust passage into the external environment.

[0042] Further, a plurality of smoke exhaust passages are arranged in the smoke exhaust device of the hookah, the number of the smoke outlet holes is multiple, and the smoke outlet holes are uniformly distributed around the second groove on the outer side of the second groove; the third opening of the smoke outlet hole is arranged on the surface of the hookah base outside the second groove, and the fourth opening is arranged on the side wall of the smoke exhaust cavity.

[0043] When in a non-puffing state or a non-smoke-exhausting state, the third seal closes the smoke exhaust passage, and when the cigarette rod penetrates through the hookah base, it is tightly fitted with the hookah base, so that the smoke exhaust cavity and the water container are in a relatively independent state, that is, in a non-puffing state or a non-smoke-exhausting state, smoke cannot enter the smoke exhaust cavity from the water container.

[0044] When the user puffs on the cigarette, the third seal opens the smoke exhaust passage, and the smoke enters the smoke exhaust cavity from the water container through the smoke exhaust passage. Since the smoke exhaust cavity communicates with the outside through the smoke outlet hole, the smoke is discharged from a plurality of smoke outlet holes, increasing the user's fun of playing with the cigarette. The arrangement of a plurality of smoke exhaust passages and smoke outlet holes improves the smoke exhaust efficiency.

[0045] For the convenience of installation, the cigarette rod of the present invention is divided into three sections. The middle section is fixed in the cigarette rod installation hole provided on the hookah base, and the other two sections are installed above and below the middle section. The three sections of the cigarette rod are connected by threads.

[0046] Compared with the prior art, the present invention has the following beneficial effects:

[0047] (1) The present invention is provided with an air valve and an exhaust device, which enables multiple people to smoke and blow smoke simultaneously without mutual interference. (2) The exhaust device of the present invention is integrated on the hookah base, making the structure compact. (3) The present invention is provided with a plurality of exhaust channels and a plurality of smoke outlet holes, which improves the exhaust efficiency and increases the fun of using the hookah for users.

Detailed implementation manners

[0073] The following combines the accompanying drawings and embodiments to further describe in detail the specific implementation manners of the present invention. The following embodiments are used to illustrate the present invention, but are not used to limit the scope of the present invention.

[0074] Hookah air valve Embodiment 1:

[0075] As Figure 1 —3 shows, a hookah air valve includes a valve spool 1. The valve spool 1 includes a suction passage 2 and a blowing passage. The suction passage 2 is provided with a first seal 7, and the first seal 7 keeps the suction passage 2 in a normally closed state. The blowing passage includes a blowing section 3, a seal moving section 4, and an air outlet section 5 arranged in sequence. The blowing section 3 is connected to the air outlet section 5 through the seal moving section 4. A first opening 10 is formed at the connection between the seal moving section 4 and the blowing section 3, and a second opening 11 is formed at the connection between the seal moving section 4 and the air outlet section 5. The seal moving section 4 is provided with a second seal 8. In the normal state, the second seal 8 is located between the first opening 10 and the second opening 11, so that the blowing section 3 is not communicated with the air outlet section 5. When a certain amount of gas is input into the blowing passage through the blowing section 3, the second seal 8 moves and connects the blowing section 3 and the air outlet section 5.

[0076] The suction and blowing sides of the hookah air valve are the acting force sides, and the other side is the non-acting force side.

[0077] During inhalation, the suction force acts on the first seal 7. As long as the suction force can overcome other forces acting on the first seal 7 and open the suction passage, the gas can reach the acting force side from the non-acting force side of the air valve.

[0078] When blowing air, the blown air will enter the blowing channel 2 through the blowing section 3. The air pressure on the blowing end side of the second seal 8 will increase. As long as the air pressure on the blowing end side of the second seal 8 can overcome other forces acting on the second seal 8 and make the second seal 8 move towards the air outlet section 5, finally connecting the blowing section 3 and the air outlet section 5, the blowing channel can be opened, and the gas can reach the non-acting force side from the acting force side.

[0079] When there is no acting force, since the first seal 7 keeps the suction channel 2 in a normally closed state; since the second seal 8 is located between the first opening 10 and the second opening 11, the blowing section 3 and the air outlet section 5 are not connected, that is, the blowing channel is in a closed state; the gas cannot reach the non-acting force side from the acting force side or from the non-acting force side to the acting force side.

[0080] Preferably, the axis of the blowing section 3 forms an angle with the axis of the seal moving section 4.

[0081] Preferably, the suction channel 2 includes a first tapered hole section and a first cylindrical hole section, and the first seal is a first sealing ball.

[0082] Adopting the tapered section design and the sealing ball design improves the sealing performance of the air valve of the present invention and facilitates the reset of the sealing ball.

[0083] Preferably, the connection line between the two points with the farthest distance on the surface of the second seal 8 is greater than the maximum width of the second opening 11, so that the second seal 8 cannot pass through the second opening 11, thereby preventing the second seal 8 from detaching from the seal moving section 4.

[0084] Preferably, except for the first opening 10 and the second opening 11, the seal moving section 4 has no other openings, ensuring that the gas blown into the blowing section 3 exits from the air outlet section 5, and at the same time preventing the second seal 8 from escaping from the seal moving area 4.

[0085] Preferably, the hookah bowl air valve includes a first connector 16, and the first connector 16 is used to connect a first external device and the air valve core 1. A first seal blocking body 18 for preventing the first seal 7 from escaping from the suction channel 2 is provided on the connection side of the first connector 16 and the air valve core 1.

[0086] Preferably, the hookah bowl air valve includes a second connector 17, and the second connector 17 is used to connect the air valve core 1 and a second external device.

[0087] The installation method adopted in this embodiment is as follows: the cavity size of the second connector 17 matches that of the two-way air valve spool 1. The two-way air valve spool 1 is fixed inside the second connector 17. One side of the first seal blocking body 18 is provided on the first connector 16 and is connected to the second connector 18. The other end of the first connector 16 is connected to a first external device, and the other end of the second connector 18 is connected to a second external device, realizing the connection between the first external device, the two-way air valve spool 1, and the second external device.

[0088] Embodiment 2 of the water pipe air valve:

[0089] As Figure 1 —2, Figure 4 As shown, a water pipe air valve includes an air valve spool. The air valve spool 1 includes an inhalation passage 2 and an exhalation passage. A first seal 7 is provided in the inhalation passage 2, and the first seal 7 keeps the inhalation passage 2 in a normally closed state. The exhalation passage includes a blowing section 3, a seal moving section 4, and an air outlet section 5 arranged in sequence. The blowing section 3 is connected to the air outlet section 5 through the seal moving section 4. A first opening 10 is formed at the connection between the seal moving section 4 and the blowing section 3, and a second opening 11 is formed at the connection between the seal moving section 4 and the air outlet section 5. A second seal 8 is provided in the seal moving section 4. In the normal state, the second seal 8 is located between the first opening 10 and the second opening 11, making the blowing section 3 and the air outlet section 5 not communicate with each other. When a certain amount of gas is input into the exhalation passage through the blowing section 3, the second seal 8 moves and connects the blowing section 3 and the air outlet section 5.

[0090] Preferably, the axis of the blowing section 3 is parallel to the axis of the seal moving section 4.

[0091] Preferably, the distance between the two farthest points on the surface of the second seal 8 is greater than the maximum width of the second opening 11, so that the second seal 8 cannot pass through the second opening 11.

[0092] Preferably, except for the first opening 10 and the second opening 11, there are no other openings in the seal moving section 4.

[0093] Preferably, the blowing section 3 includes an air cavity 6. One end of the blowing section 3 is connected to the air cavity 6, and one end of the seal moving section 4 is connected to the air cavity 6. The first opening 10 is formed at the connection between the air cavity 6 and the seal moving section 4.

[0094] Preferably, the air outlet section 5 includes a connecting section 9. The air outlet section 5 is connected to the seal moving section 4 through the connecting section 9. The second opening 11 is formed at the connection between the connecting section 9 and the seal moving section 4.

[0095] The structures of the first connecting member 16 and the second connecting member 17 and the connection relationship between the first connecting member 16, the second connecting member 17, the air valve core 1, the first external device and the second external device in this embodiment are the same as those in the first embodiment.

[0096] The air intake process and the no-force state of this embodiment are the same as those of Embodiment 1, but when blowing, the blown air will enter the air cavity 6 through the blowing section 3, and the air pressure in the air cavity will increase. As long as the air pressure in the air cavity 6 can overcome other forces acting on the second sealing member 8 and move the second sealing member 8 toward the air outlet section 5, and finally connect the blowing section 3 and the air outlet section 5, the blowing channel can be opened, and the gas can reach the non-force side from the force side.

[0097] like Figure 5 As shown in FIG. 8 , preferably, since the purpose of the connecting section 9 is to connect the air outlet section 5 with the seal movable section 4, for the convenience of processing, the air outlet section 5 and the upper end of the seal movable section 4 are directly opened in this embodiment to form a first groove 38 with a first sealing cover 15, so as to realize the connection between the air outlet section 5 and the seal movable section 4 and ensure the overall sealing. The second opening is arranged in the first groove 38.

[0098] Likewise, for the convenience of processing, the air cavity 6 is a third groove having a second sealing cover 37 .

[0099] like Figure 6 As shown, preferably, the line connecting the two farthest points on the surface of the second seal 8 is larger than the maximum width of the second opening 11, so that the second seal 8 cannot pass through the second opening 11; if the seal active area and the air outlet section are connected in the form of a groove, causing the second opening 11 to become larger, an inward protrusion is used at the second opening 11 to form a second seal blocking body 19.

[0100] Hookah air valve embodiment 3:

[0101] like Figure 1 —2. Figure 9As shown in FIGS. 1 - 13, a water pipe valve includes a valve core. The valve core 1 includes an inhalation passage 2 and an exhalation passage. The inhalation passage 2 is provided with a first seal 7, which keeps the inhalation passage 2 in a normally closed state. The exhalation passage includes an exhalation section 3, a seal movable section 4, and an air outlet section 5. One end of the exhalation section 3 is connected to an air chamber 6. One end of the seal movable section 4 is connected to and communicates with the air chamber 6. The air chamber 6 and the seal movable section 4 form a first opening 10. The seal movable section 4 is provided with a second seal 8. The air outlet section 5 includes a connecting section 9. The air outlet section 5 communicates with the seal movable section 4 through the connecting section 9. The connection between the connecting section 9 and the seal movable section 4 forms a second opening 11. The second seal 8 is located between the first opening 10 and the second opening 11, so that the exhalation section 3 and the air outlet section 5 are not in communication under normal conditions. When a certain amount of gas is input into the exhalation passage through the exhalation section 3, the second seal 8 moves and connects the exhalation section 3 and the air outlet section 5.

[0102] Preferably, the axis of the exhalation section 3, the axis of the seal movable section 4, and the axis of the air outlet section are parallel to each other or form an angle.

[0103] Preferably, the second seal 8 keeps the seal movable section 4 and the air outlet section 5 not in communication under normal conditions.

[0104] Preferably, the seal movable section 4 is further provided with a fourth seal, which cooperates with the second seal 8 to keep the seal movable section 4 and the air outlet section 5 not in communication under normal conditions.

[0105] If the seal movable section 4 and the air outlet section 5 are in communication under normal conditions, when others inhale forcefully, the gas above the second seal 8 will be sucked out by others through the air outlet section 5, resulting in a decrease in the air pressure above the second seal 8, thus causing the second seal 8 to open and connect the exhalation section 3 and the air outlet section 5. Therefore, the seal movable section 4 and the air outlet section 5 are not in communication under normal conditions, and two seals can form a sealed chamber to achieve a better sealing effect.

[0106] Preferably, a through hole 12 is opened at one end of the seal movable section 4 away from the first opening 10, connecting the upper part of the seal movable section 4 to the outside, making it easier to blow the seal.

[0107] Such as Figure 9As shown, the second seal 8 is a long seal that matches the size of the movable section 4 of the shown seal. Its length enables the movable section 4 of the seal and the air outlet section 5 to be not in communication under normal conditions. However, during long-term use, water vapor will be generated on the surface of the movable section 4 of the seal, causing stickiness between the second seal 8 and the surface of the movable section 4 of the seal, resulting in a slow return of the second seal 8; such as Figure 10 As shown, the second seal 8 is improved by indenting the middle section of the second seal 8 inward to reduce the contact area between the second seal 8 and the surface of the movable section 4 of the seal.

[0108] Such as Figure 11 As shown, the second seal 4 is a second sealing ball, and the fourth seal 13 is a sealing sleeve. The length of the sealing sleeve enables the movable section 4 of the seal and the air outlet section 5 to be not in communication under normal conditions. However, during long-term use, water vapor will be generated on the surface of the movable section 4 of the seal, causing stickiness between the sealing sleeve and the surface of the movable section 4 of the seal, resulting in a slow return of the sealing sleeve; such as Figure 12 As shown, the fourth seal 13 is a fourth sealing ball to reduce the contact area between the seal and the surface of the movable section 4 of the seal. A sealing cavity is formed between the second sealing ball and the fourth sealing ball to achieve a better sealing effect. When others inhale, the gas between the second sealing ball and the fourth sealing ball is sucked out, and the air pressure decreases. Since the through hole is connected to the outside world, the air pressure above the fourth sealing ball is greater than the air pressure below, and the fourth sealing ball presses down on the second sealing ball, so that the second sealing ball still makes the blowing section and the air outlet section not in communication.

[0109] The structure of the first connector 16 in this embodiment and the connection relationship between the first connector 16, the second connector 17, the air valve spool 1, the first external device and the second external device are the same as those in Embodiment 1. The second connector 17 is provided with a hole that matches the through hole 12 provided in the movable section 4 of the seal.

[0110] Water pipe air valve Embodiment 4:

[0111] Such as Figure 14As shown in FIG. 18, a water pipe air valve includes an air valve core. The air valve core 1 includes an inhalation passage 2 and an exhalation passage. A first seal 7 is provided in the inhalation passage 2, and the first seal 7 keeps the inhalation passage 2 in a normally closed state. The exhalation passage includes an exhalation section 3, a seal moving section 4, and an air outlet section 5. One end of the exhalation section 3 is connected to the air cavity 6. One end of the seal moving section 4 is connected to and communicates with the air cavity 6. The air cavity 6 and the seal moving section 4 form a first opening 10. A second seal 8 is provided in the seal moving section 4. The air outlet section 5 includes a connecting section 9. The air outlet section 5 communicates with the seal moving section 4 through the connecting section 9. The connection between the connecting section 9 and the seal moving section 4 forms a second opening 11. The second seal 8 is located between the first opening 10 and the second opening 11, so that the exhalation section 3 and the air outlet section 5 are not in communication under normal conditions. When a certain amount of gas is input into the exhalation passage through the exhalation section 3, the second seal 8 moves and connects the exhalation section 3 and the air outlet section 5.

[0112] Preferably, the axis of the exhalation section 3, the axis of the seal moving section 4, and the axis of the air outlet section are parallel to each other or form an angle.

[0113] Preferably, the air outlet section 5 and the inhalation passage 2 share a through-hole penetrating the valve core, and the first opening 10 is located below the first seal 7.

[0114] Preferably, the air outlet section 5 includes a connecting section 9. The air outlet section 5 communicates with the seal moving section 4 through the connecting section 9. The connection between the connecting section 9 and the seal moving section 4 forms a second opening 11.

[0115] Preferably, the air outlet section 5 and the inhalation passage 2 share a through-hole penetrating the valve core. When a connecting section is provided, the connection between the connecting section 9 and the inhalation passage 2 (i.e., the air outlet section 5) forms a fifth opening 14, and the fifth opening 14 is located below the first seal 7.

[0116] The inhalation process in this embodiment is the same as that in Embodiment 1. However, when blowing, the exhaled air will enter the air cavity 6 through the exhalation section 3, and the air pressure in the air cavity 6 will increase. As long as the air pressure in the air cavity 6 can overcome other forces acting on the second seal 8 and make the second seal 8 move towards the inhalation passage 2 (i.e., the air outlet section 5), and finally connect the exhalation section 3 and the inhalation passage 2 (i.e., the air outlet section 5), the exhalation passage can be opened, and the acting side of the inhalation passage 2 is in a sealed state under the action of the first seal gas 7, and the gas reaches the non-acting side from the acting side.

[0117] Preferably, the second seal 8 is configured such that the movable section 4 of the seal and the air outlet section 5 are not in communication under normal conditions, or a fourth seal is further provided on the movable section 4 of the seal, and the fourth seal cooperates with the second seal 8 to ensure that the movable section 4 of the seal and the air outlet section 5 are not in communication under normal conditions.

[0118] Preferably, a through hole 12 is formed at one end of the movable section 4 of the seal away from the first opening 10.

[0119] The structure of the first connector 16 in this embodiment and the connection relationships among the first connector 16, the second connector 17, the air valve spool 1, the first external device, and the second external device are the same as those in Embodiment 1. The second connector 17 is provided with a hole that matches the through hole 12 provided on the movable section 4 of the seal.

[0120] Water pipe embodiment:

[0121] As Figure 19 — shown in Fig. 24, a water pipe includes a tobacco pot 20, a charcoal tray 21, a tobacco rod 22, a water pipe base 23, and a water container 24 that are connected in sequence from top to bottom. The tobacco rod 22 passes through the water pipe base 23 and is placed in the water container 24. The water pipe base 23 is provided with one or more blowing and suction channels 25, and each blowing and suction channel 25 is provided with an air valve 26. The air valve 26 adopts the novel water pipe air valve of the present invention. The water pipe base 23 is provided with an exhaust device 27, and the exhaust device 27 is provided with an exhaust channel 28. A third seal 29 is provided in the exhaust channel 28, and the third seal 29 keeps the exhaust channel 28 in a normally closed state; the external force required to open the exhaust channel 28 by the third seal 29 is smaller than that required to open the suction channel 2 by the first seal 7.

[0122] The water container 24 is filled with water, and the end of the tobacco rod 22 is immersed in the water; each air valve 26 is connected to a hose, and the end of the hose is provided with a mouthpiece for sucking and blowing smoke. Multiple blowing and suction channels 25 are provided to allow multiple people to smoke simultaneously.

[0123] When smoking, the user inhales through the hose. As long as the suction force can overcome other forces acting on the first seal 7 and open the suction channel 2, the water pressure above the water in the water container 24 will ultimately decrease, and the external air pressure will press the smoked tobacco after combustion into the water container 24. After passing through the water, the smoked tobacco is inhaled by the user through the suction channel 2 and the hose.

[0124] When blowing smoke, the user blows air into the hose, and the blown air will enter the blowing channel 2 through the blowing section 3. The air pressure on the blowing end side of the second seal 8 will increase. As long as the air pressure on the blowing end side of the second seal 8 can overcome other forces acting on the second seal 8 and make the second seal 8 move towards the air outlet section 5, the blowing section 3 and the air outlet section 5 will be finally connected. The gas reaches the air outlet section from the blowing end, and finally reaches the water-containing container 24, and the water pressure on the water in the water-containing container 24 increases. When the internal pressure of the water-containing container 24 is greater than the external pressure, the third seal 29 opens the smoke exhaust channel 28, and the excess smoke on the water in the water-containing container 24 is discharged from the smoke exhaust channel 28. Under the action of an external force, the external force required for the third seal 29 to open the smoke exhaust channel 22 is smaller than that for the first seal 7 to open the air intake channel 2. Therefore, when the internal pressure of the water-containing container 24 is greater than the external pressure, the third seal 29 is opened, and the first seal 7 still closes the air intake channel 2.

[0125] When not blowing and smoking, since the first seal 7 keeps the air intake channel 2 in a normally closed state; since the second seal 8 disconnects the blowing section 3 from the air outlet section 5, the blowing channel is closed.

[0126] As Figure 24 shown, if the air intake channel 2 and the smoke exhaust channel 28 are arranged in parallel and vertically, under the action of gravity, the first seal 7 and the third seal 29 respectively keep the air intake channel 2 and the smoke exhaust channel 28 in a normally closed state. As long as the mass of the third seal 29 is less than that of the first seal 7, when the gas enters the water-containing container 24 through the air outlet section 5 and the air pressure in the water-containing container 24 increases, the third seal 29 preferentially opens the smoke exhaust channel 28, and the first seal 7 still keeps the air intake channel 2 in a closed state; the above situation is that the external force required for the third seal 29 to open the smoke exhaust channel 28 is smaller than that for the first seal 7 to open the air intake channel 2.

[0127] Preferably, the smoke exhaust channel 28 includes a third tapered hole section and a third cylindrical hole section connected in sequence, and the third seal 29 is a third sealing ball, which improves the sealing performance of the hookah of the present invention and is beneficial to the reset of the third sealing ball.

[0128] Preferably, the smoke exhaust device 27 is integrated on the hookah base 23, and the smoke exhaust device 27 is provided with a third cover 32 for preventing the third seal 29 from escaping from the smoke exhaust channel 28.

[0129] Integrating the smoke exhaust device 27 on the hookah base 23 makes the structure of the present invention compact.

[0130] Preferably, the top of the hookah base 23 is recessed inward to form a second groove 31. The smoke exhaust passage 28 is provided at the bottom end of the second groove 31. A tobacco rod mounting hole 32 is provided at the center positions of the second groove 31 and the third cover 30. A tobacco rod 22 matching the size of the tobacco rod mounting hole 32 is penetrated through the tobacco rod mounting hole 32. The tobacco rod 22 is tightly fitted with the hookah base 23 through the tobacco rod mounting hole 32. A smoke exhaust cavity 33 is formed between the inner wall of the second groove 31 and the outer wall of the tobacco rod 22. The third cover 30 matches the smoke exhaust cavity 33 and exactly covers the top of the smoke exhaust cavity 33. A smoke outlet hole 34 is opened on the hookah base 23. The smoke exhaust cavity 33 communicates with the outside through the smoke outlet hole 34.

[0131] The smoke outlet hole 34 discharges the smoke discharged from the smoke exhaust passage 28 into the smoke exhaust cavity 33 to the outside.

[0132] Preferably, a plurality of smoke exhaust passages 28 are provided in the smoke exhaust device 27. The number of the smoke outlet holes 34 is multiple, and the smoke outlet holes 34 are evenly distributed around the second groove 31 on the outside of the second groove 31. The third opening 35 of the smoke outlet hole 34 is provided on the surface of the hookah base 23 outside the second groove 31, and the fourth opening 36 is provided on the side wall of the smoke exhaust cavity 33.

[0133] When in a non-smoking-blowing state or a non-smoke-exhausting state, the third seal 29 closes the smoke exhaust passage 28. When the tobacco rod 22 penetrates through the hookah base 23, it is tightly fitted with the hookah base 23, so that the smoke exhaust cavity 33 and the water-containing container 24 are in a relatively independent state, that is, in a non-smoking-blowing state or a non-smoke-exhausting state, smoke cannot enter the smoke exhaust cavity 33 from the water-containing container 24.

[0134] When the user blows smoke, the third seal 29 opens the smoke exhaust passage 28. The smoke enters the smoke exhaust cavity 33 from the water-containing container 24 through the smoke exhaust passage 28. Since the smoke exhaust cavity 33 communicates with the outside through the smoke outlet holes 34, the smoke is discharged from a plurality of smoke outlet holes 34, increasing the fun of the user playing with the tobacco. The provision of a plurality of smoke exhaust passages 28 and smoke outlet holes 34 improves the smoke exhaust efficiency.

[0135] For convenient installation, the tobacco rod 22 of the present invention is divided into three sections. The middle section is fixed in the tobacco rod mounting hole 32 provided on the hookah base 23, and the other two sections are installed above and below the middle section. The three sections of the tobacco rod are connected by threads.

[0136] The above are only the preferred embodiments of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the technical principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
