[0017] A hookah pipe, comprising a water storage pipe 1, one end of the water storage pipe 1 is threadedly connected with a first one-way valve 2, the other end of the water storage pipe 1 is threadedly connected with one end of a second one-way valve 3, and the other end of the second one-way valve 3 is threadedly connected with a mouthpiece 4; inside the first one-way valve 2, there are a first flue 201 and a second flue 202, the first flue 201 and the second flue 202 are perpendicularly arranged, and a smoke passing hole 203 is communicated between the first flue 201 and the second flue 202; the top of the first flue 201 is threadedly connected with a tobacco rod head 5, inside the second flue 202, there are arranged a sealing steel ball 6, a first spring 7 and a compression spring screw 8, both sides of the sealing steel ball 6 are respectively abutted against the smoke passing hole 203 and the first spring 7, the compression spring screw 8 is threadedly connected with the second flue 202, and the compression spring screw 8 is abutted against the first spring 7; inside the second one-way valve 3, there is a stepped portion 301, a stepped hole 302 is opened in the stepped portion 301, a ventilation rod 9 is inserted into the stepped hole 302, an external thread of the ventilation rod 9 is threadedly connected with a one-way valve nut 10, and a second spring 11 is abutted between the one-way valve nut 10 and the stepped portion 301.

[0018] Further, in another embodiment, one end of the compression spring screw 8 is provided with an internal hexagonal hole 801, and the other end is provided with a spring placement hole 802, and the internal hexagonal hole 801 is communicated with the spring placement hole 802.

[0019] The design of the internal hexagonal hole 801 of the compression spring screw 8 facilitates the installation and adjustment of the first spring 7, improves the assembly convenience and maintainability; and the internal hexagonal hole 801 is communicated with the spring placement hole 802, enabling the user to smoothly pass through when inhaling the smoke.

[0020] Further, in another embodiment, a smoking port 401 is opened at the end of the mouthpiece 4.

[0021] The design of the smoking port 401 at the end of the mouthpiece 4 facilitates the user to inhale the smoke.

[0022] Further, in another embodiment, a tobacco placement port 501 is opened at the top of the tobacco rod head 5, and a smoke passing pipeline 502 is communicated with the bottom of the tobacco placement port 501.

[0023] The design of the tobacco placement port 501 at the top of the tobacco rod head 5 and the smoke passing pipeline 502 communicated with the bottom makes it more convenient to place the tobacco, and at the same time ensures the smooth flow of the smoke.

[0024] Further, in another embodiment, the ventilation rod 9 includes a base 901 and a rod portion 902. The base 901 abuts against the side wall of the stepped portion 301. An air vent duct 903 is provided inside the rod portion 902, and a through hole 904 communicating with the air vent duct 903 is provided on the side wall of the rod portion 902.

[0025] The design of the base 901 and the rod portion 902 of the ventilation rod 9, as well as the arrangement of the air vent duct 903 and the through hole 904, further improve the ventilation efficiency, ensuring the smoothness during smoking and the filtering effect of the smoke.

[0026] The working principle of an embodiment of the present utility model is as follows:

[0027] When the user inhales through the smoking port 401, under the action of suction, a negative pressure is generated inside the mouthpiece 4, forcing the ventilation rod 9 in the second one-way valve 3 to move to the right. At the same time, a negative pressure is generated inside the water storage pipe 1, forcing the sealing steel ball 6 in the first one-way valve 2 to move to the right. Then the smoke enters the first flue 201 of the first one-way valve 2 through the smoke passage pipe 502, and then enters the second flue 202 through the smoke through hole 203. The sealing steel ball 6 and the first spring 7 inside the second flue 202 ensure the unidirectional flow of the smoke, preventing the leakage of water and smoke. Then the smoke enters the water storage pipe 1 through the compression spring screw 8, and then the smoke contacts and filters with 2 / 3 of the water stored in the water storage pipe 1. The filtered smoke enters the air vent duct 903 of the ventilation rod 9 and then flows out through the through hole 904, and finally is inhaled by the user through the mouthpiece 4.

[0028] When not smoking, the sealing steel ball 6 in the first one-way valve 2 contacts the smoke through hole 203 under the action of the first spring 7. Since the diameter of the sealing steel ball 6 is larger than the diameter of the smoke through hole 203, it is ensured that the sealing steel ball 6 and the edge of the smoke through hole 203 achieve a sealing effect. At the same time, the ventilation rod 9 in the second one-way valve 3 is threadedly connected with a one-way valve nut 10. Under the action of the second spring 11, the ventilation rod 9 moves to the left, ensuring that the through hole 904 and the side wall of the stepped hole 302 achieve a sealing effect, thereby preventing water from leaking at the first one-way valve 2 and the second one-way valve 3.
