DETAILED DESCRIPTION

[0027] The concept, specific structure and generated technical effects of the utility model will be clearly and completely described below in combination with the embodiments and drawings, so as to fully understand the purpose, features and effects of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, but not all the embodiments, and other embodiments obtained by the person skilled in the art without creative labor based on the embodiments of the utility model all belong to the protection scope of the utility model. In addition, all the coupling / connection relations involved in the patent do not mean that the components directly connect, but means that a better coupling structure can be formed by adding or reducing coupling auxiliary components according to the specific implementation situation. The various technical features in the utility model creation can be interactively combined without mutual contradiction and conflict.

[0028] With reference to Figure 1 , 2 , 4, the liquid leakage prevention mechanism comprises a sealing cover body 1 and a sealing control assembly 2 arranged on the sealing cover body 1, wherein the sealing control assembly 2 is composed of a toggle plate 21 and a sealing gasket 22. The sealing cover body 1 is provided with a mounting portion 11, and the air inlet hole 12 and the air outlet hole 13 are distributed along the circumference of the mounting portion 11. The toggle plate 21 is provided with a first flow guide through hole 211, and the sealing gasket 22 is provided with a second flow guide through hole 223, and the two flow guide through holes correspond in position. When the user needs to use the portable hookah, the sealing control assembly 2 can be adjusted to the first working position, at this time, the first flow guide through hole 211 and the second flow guide through hole 223 correspond in position with the air inlet hole 12 and the air outlet hole 13, so that the air inlet hole 12 and the air outlet hole 13 are in a communication state, which is convenient for the normal use of the hookah equipment; when the user needs to carry the hookah equipment, the sealing control assembly 2 can be adjusted to the second working position, at this time, the first flow guide through hole 211 and the second flow guide through hole 223 are staggered with the air inlet hole 12 and the air outlet hole 13, so that the air inlet hole 12 and the air outlet hole 13 are in a sealed state, thereby preventing the liquid in the water tank from leaking out or flowing back. Since the toggle plate 21 and the sealing gasket 22 are detachably connected, the sealing gasket 22 can be replaced or cleaned and maintained, thereby further improving the service life of the equipment.

[0029] Specifically, with reference to Figures 2-4 , two first flow guide through holes 211 and two second flow guide through holes 223 are arranged, and the sizes of these through holes are completely the same and one-to-one corresponding, forming two complete flow guide channels. The two channels correspond to the positions of the air inlet hole 12 and the air outlet hole respectively.

[0030] In some embodiments, the first flow guide through hole 211 is arranged on an arc with the mounting portion 11 as the center and the distance from the mounting portion 11 to the air inlet hole 12 as the radius, and the second flow guide through hole 223 is arranged on an arc with the mounting portion 11 as the center and the distance from the mounting portion 11 to the air outlet hole 13 as the radius. When the user needs to use the portable hookah, rotating the knob 21 will drive the first flow guide through hole 211 and the second flow guide through hole 223 to move along the respective arc trajectories. When rotated to the first working position, the two flow guide through holes are in position corresponding to the air inlet hole 12 and the air outlet hole 13, realizing normal flow of the liquid. When the portable hookah device needs to be carried, continue to rotate the knob 21 to the second working position, and the two flow guide through holes will move along the arc to positions offset from the air inlet hole 12 and the air outlet hole 13, thereby realizing the sealing effect. The structure of arranging and moving along the arc ensures that the flow guide through holes can always maintain the correct relative positional relationship with the air inlet hole 12 and the air outlet hole 13 during rotation, improving the accuracy and reliability of the sealing control.

[0031] Further, the first flow guide through hole 211 and the second flow guide through hole 223 are arranged on the same arc trajectory, that is, on the same circumference with the mounting portion 11 as the center, that is, the two flow guide through holes always maintain the same rotational radius, thereby being able to move synchronously. When the user uses the portable hookah, rotate the knob 21 to the first working position, and the two flow guide through holes will simultaneously reach positions corresponding to the air inlet hole 12 and the air outlet hole 13. When the device needs to be carried, rotate the knob 21 to the second working position, and the two flow guide through holes will also synchronously move to positions offset from the air inlet hole 12 and the air outlet hole 13.

[0032] In some embodiments, referring to Figures 2-6 , a detachable cooperation structure is designed between the knob 21 and the sealing gasket 22. Specifically, a protrusion 212 is arranged on the knob 21 along the circumference of the first flow guide through hole 211, a groove 224 corresponding to the protrusion 212 is arranged on the sealing gasket 22 along the circumference of the second flow guide through hole 223, and the protrusion 212 and the groove 224 are connected in an interference fit. When in use, the interference fit ensures that the knob 21 can drive the sealing gasket 22 to rotate synchronously when the knob 21 rotates, so that the two flow guide through holes always maintain the same relative position. At the same time, when the sealing gasket 22 needs to be replaced or cleaned and maintained, the sealing gasket 22 can be removed from the knob 21 by overcoming the interference force.

[0033] Further, the cooperation structure on the knob 21 and the sealing gasket 22 of the liquid leakage prevention mechanism adopts an arc design, that is, the protrusion 212 on the knob 21 and the groove 224 on the sealing gasket 22 are both arranged in an arc shape, and the arc degrees of the two are matched with each other.

[0034] In some embodiments, referring to Figure 5In the bottom surface of the sealing gasket 22, two types of sealing protrusions are designed, wherein the first sealing protrusion 221 is arranged around the two second flow guide through holes 223, and the second sealing protrusion 222 is arranged at a specific angle relative to the first sealing protrusion 221 and centered on the mounting portion 11. The design of the double sealing protrusions ensures reliable sealing in different use states of the portable hookah: when the user needs to use the hookah, the sealing control assembly 2 is turned to the first working position, at which time the first sealing protrusion 221 abuts tightly with the air inlet hole 12 and the air outlet hole 13, forming a sealing ring around the flow guide through hole and preventing liquid from leaking around the hole; when the user needs to carry the hookah equipment, the sealing control assembly 2 is turned to the second working position, at which time the second sealing protrusion 222 abuts tightly with the air inlet hole 12 and the air outlet hole 13, completely closing the liquid passage. For example, when the user needs to carry the hookah equipment, the abutting sealing of the second sealing protrusion 222 can effectively prevent the liquid in the water tank from leaking, and even if the equipment is tilted or shaken, the sealing performance can still be good.

[0035] In some embodiments, with reference to Figure 1 、 3 The liquid leakage prevention mechanism is provided with a limiting column 14 on the sealing cover 1, and an arc-shaped limiting groove 213 is correspondingly provided on the tab 21. When the limiting column 14 is embedded in the arc-shaped limiting groove 213, the rotation range of the tab 21 can be effectively limited, preventing excessive rotation. This makes the portable hookah more controllable during use: when the user operates the tab 21 to rotate, the limiting column 14 will slide in the arc-shaped limiting groove 213 and stop when it reaches the first working position or the second working position, avoiding sealing failure caused by excessive rotation. For example, when the user needs to switch the sealing state, he only needs to rotate the tab 21 until he feels the limiting resistance, which can ensure that the flow guide through hole has been accurately rotated into place. This design not only simplifies the operation, but also prevents the user from damaging the sealing structure due to excessive rotation.

[0036] In some embodiments, with reference to Figure 1 、 3A first magnet 15 and a second magnet 16 are arranged on the sealing cover 1 respectively, and a third magnet 214 is arranged on the dial 21, so as to realize accurate positioning and fixing through magnetic interaction. When the portable hookah is in use, the dial 21 is rotated to a first working position, at this time, the third magnet 214 on the dial 21 will generate an attractive force with the first magnet 15 on the sealing cover 1, so as to fix the dial 21 in the working position stably; when the user needs to carry the equipment, the dial 21 is rotated to a second working position, the third magnet 214 will generate an attractive force with the second magnet 16, so as to fix the dial 21 in the sealing position firmly. For example, when the user is in the process of moving, even if the equipment is shaken or tilted, the magnetic force can ensure that the dial 21 remains in the sealing position, preventing accidental rotation from causing liquid leakage, and the magnetic positioning can also provide a clear feedback to the user when the user is operating.

[0037] In some embodiments, reference is made to Figures 1-3 The liquid leakage prevention mechanism is provided with an identification gap 215 on the dial 21, and a position identifier 17 corresponding to the identification gap 215 is arranged on the sealing cover 1, so as to intuitively display the working state of the dial 21 through the relative position relationship between the two. Through the visual design, the working state of the portable hookah can be known at a glance: when the dial 21 is in the first working position, the identification gap 215 will form a specific corresponding relationship with the position identifier 17 on the sealing cover 1, indicating that the equipment is in a usable state; when the dial 21 is rotated to the second working position, the identification gap 215 will form another corresponding relationship with the position identifier 17, indicating that the equipment is in a sealing state. For example, when the user needs to confirm whether the hookah equipment is in a sealing state, the user only needs to observe the relative position of the identification gap 215 and the position identifier 17, and this intuitive visual prompt can help the user to quickly judge the equipment state, avoiding liquid leakage caused by incorrect state judgment.

[0038] The above is a specific description of the preferred embodiment of the utility model, but the utility model is not limited to the described embodiments, and those skilled in the art can make various equivalent modifications or replacements without departing from the spirit of the utility model, and these equivalent modifications or replacements are all included in the range defined by the claims of the present application.
