[0035] In order to make the technical problems, technical solutions and beneficial effects solved by the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not intended to limit the present invention.

[0036] like Figure 1 and Figure 2 As shown, an embodiment of the present invention provides an electronic hookah, comprising a housing 1 , wherein the housing 1 has a base 2 , a control module 8 , an atomization module 6 and an air guide tube 3 , and the base 2 is provided with a liquid storage chamber 21 for holding liquid.

[0037] The control module 8 includes a power supply unit, a control unit, and an air suction passage 81 for sucking smoke. The air suction passage 81 is in communication with the liquid storage chamber 21 .

[0038] The atomizing module 6 is electrically connected to the control module 8, which is used to control the atomizing module 6 to atomize the smoke liquid when smoking the electronic hookah. The base 2, the control module 8 and the atomizing module 6 are connected in sequence along the longitudinal direction. Figure 2 In the X direction.

[0039] The head end of the air guide tube 3 is connected to the atomization module 6 , and the tail end of the air guide tube 3 is submerged in the liquid in the liquid storage chamber 21 .

[0040] The top cover of the atomizer module 6 is provided with a top cover 4, forming an airflow gap 11 between the top cover 4 and the atomizer module 6. When inhaling through the airway 81, air enters the atomizer module 6 through the airflow gap 11 and mixes with the atomized tobacco liquid in the atomizer module 6 to form an aerosol. Some of the aerosol is filtered through the liquid in the liquid storage chamber 21 at the end of the air guide tube 3 before escaping from the airway 81. When inhaling through the airway 81 stops, some of the aerosol escapes from the airflow gap 11 to the outside due to the pressure of the liquid surface in the liquid storage chamber 21.

[0041] Specifically, Figures 3 to 5 The arrows in the figure indicate the direction of gas flow. Figure 3 and Figure 4 As shown, when the user draws, the control module 8 activates the atomization module 6 to heat the smoke liquid and atomize it. Air enters the atomization module 6 through the air flow gap 11 and mixes with the atomized smoke liquid to form an aerosol. Figure 5 As shown, the aerosol is transmitted to the liquid storage chamber 21 through the airway tube 3. The air pressure in the liquid storage chamber 21 decreases, causing the liquid level to rise from position A to position B, and at the same time, bubbles are generated around the airway tube 3. After being filtered by the liquid, the aerosol escapes through the suction channel 81 for inhalation by the user.

[0042] like Figures 6 to 8As shown in the figure, the direction of gas flow is indicated by the arrow. When the user stops smoking the electronic hookah, the air pressure in the liquid storage chamber 21 recovers, causing the liquid level to drop and exerting reverse pressure on the remaining aerosol in the airway 3. This causes some of the aerosol to flow back along the airway 3 and escape through the airflow gap 11 at the top, creating a smoke back-spray effect, thereby enhancing the user's smoking experience.

[0043] In one embodiment, the liquid in the liquid storage chamber 21 is water. Specifically, the liquid in the liquid storage chamber 21 can filter harmful substances in the aerosol, cool the aerosol, or enhance the taste of the inhaled liquid by adding flavoring ingredients to the liquid. The liquid can be replaced at any time as needed. Specifically, the liquid is not limited to water, juice, beverages, coffee, etc.

[0044] In one embodiment, if Figures 3 to 8 As shown, the air flow gap 11 includes a first air flow gap 13 and a second air flow gap 14 . The first air flow gap 13 is connected to the outside, and the second air flow gap 14 is connected to the atomization module 6 .

[0045] The airflow gap 11 of the electronic hookah is set to accurately control the mixing ratio of air and aerosol, and simulate the airflow feeling during traditional smoking. The first airflow gap 13 is connected to the outside world, allowing outside air to enter, while the second airflow gap 14 is connected to the atomization module 6, so that the air and the atomized smoke liquid are mixed to form an aerosol. This design ensures that when the user inhales, they can experience airflow dynamics similar to those during traditional smoking, optimizing the generation and transmission efficiency of aerosols. At the same time, it also promotes the flow of some uninhaled aerosols in the air duct 3 when they overflow from the top cover 4, significantly improving the visual effect of the smoky smoke and creating a richer and more fascinating atmosphere.

[0046] In one embodiment, if Figure 2 and Figure 9 As shown, a mounting groove 15 is provided at the top of the housing 1 , and the top cover 4 is disposed in the mounting groove 15 .

[0047] A first air flow gap 13 is formed between the outer wall of the top cover 4 and the side wall of the installation groove 15, and a second air flow gap 14 is formed between the bottom of the top cover 4 and the bottom wall of the installation groove 15. The atomization module 6 is connected to the outside through the second air flow gap 14 and the first air flow gap 13.

[0048] When a user inhales, outside air enters through the first airflow gap 13, passes through the second airflow gap 14, and mixes with the atomized tobacco liquid in the atomizer module 6 to form an aerosol for the user to inhale. When the user stops inhaling, the aerosol remaining in the airway 3 is forced by reverse pressure to flow toward the atomizer module 6, passing through the second airflow gap 14 to the first airflow gap 13. It then gently escapes from the first airflow gap 13, circling and swirling around the top cover 4, forming a swirling layer of smoke.

[0049] In one embodiment, if Figures 9 to 11 As shown, a rib 41 protruding outward is provided on the outer wall of the top cover 4 , and the rib 41 is abutted against a portion of the side wall of the mounting groove 15 . A gap is formed between the outer wall of the top cover 4 and the side wall of the mounting groove 15 to form a first airflow gap 13 .

[0050] The convex rib 41 can not only radially position the top cover 4, but also form a first airflow gap 13 between the outer wall of the top cover 4 and the side wall of the mounting groove 15, simplifying the structure of the top cover 4 and the outer shell 1 to optimize the air flow path, improve the aerosol transmission efficiency, and enhance the smoke-filled effect during use, thereby significantly improving the user's sensory experience.

[0051] In one embodiment, a plurality of ribs 41 are provided, and the plurality of ribs 41 are spaced apart and distributed around the outer sidewall of the top cover 4. The plurality of ribs 41 spaced apart and distributed around the outer sidewall of the top cover 4 not only optimizes the air flow path and improves the aerosol transmission efficiency, but also enhances the smoke-enveloping effect during use, significantly improving the user's sensory experience.

[0052] In one embodiment, if Figure 11 As shown, the rib 41 is in the shape of an elongated strip, and the rib 41 extends along the circumferential direction of the outer side wall of the top cover 4. The structure of the elongated rib 41 is simple.

[0053] In one embodiment, if Figures 9 to 11 As shown, a positioning support member 42 is provided on the bottom of the top cover 4, and a positioning groove 16 is provided on the bottom wall of the mounting groove 15 for cooperating with the positioning support member 42. The positioning support member 42 is inserted into the positioning groove 16, and the length of the positioning support member 42 is greater than the depth of the positioning groove 16, so that a second airflow gap 14 is formed between the bottom of the top cover 4 and the bottom wall of the mounting groove 15.

[0054] Specifically, the positioning support 42 is lengthened so that its length exceeds the depth of the positioning groove 16, ensuring that when the top cover 4 is assembled into the mounting groove 15, a completely sealed state is not formed between the two, thereby forming a gap between the bottom of the top cover 4 and the bottom wall of the mounting groove 15, namely the second airflow gap 14. This structure not only effectively adjusts the airflow path and optimizes the overall airflow dynamics, but also plays a role in circumferentially positioning the top cover 4, ensuring the correct position of the top cover 4. The abutment between the positioning support 42 and the outer shell 1 simplifies the structural design of the top cover 4 and the outer shell 1, making the entire device more compact and more functional.

[0055] In one embodiment, if Figure 9 and Figure 11As shown, the cross-sectional shape of the positioning support member 42 may be circular, and the positioning groove 16 is a circular groove adapted to the outer shape of the positioning support member 42 , so that the positioning support member 42 can be easily inserted into the positioning groove 16 .

[0056] In one embodiment, two positioning support members 42 are provided.

[0057] In other embodiments, the cross-section of the positioning support member 42 may be square. In this case, the number of the positioning support members 42 may be one or two or more.

[0058] In one embodiment, the notch of the positioning groove 16 is provided with rounded corners to facilitate the insertion of the positioning support member 42 into the positioning groove 16 .

[0059] In one embodiment, if Figure 9 and Figure 11 As shown, a first magnetic member 12 is mounted on the bottom wall of the mounting groove 15, and a second magnetic member 43 is mounted on the top cover 4 to cooperate with the first magnetic member 12 for magnetic attraction, thereby securing the top cover 4 to the housing 1. Using magnetic attraction to secure the top cover 4 to the housing 1 provides a simple structure and facilitates assembly and disassembly.

[0060] In one embodiment, the first magnetic member 12 is a magnet.

[0061] In one embodiment, the second magnetic member 43 is a metal member, such as an iron sheet.

[0062] In one embodiment, four second magnetic members 43 are provided, and correspondingly, four first magnetic members 12 are provided. The four first magnetic members 12 are distributed along the circumference of the installation slot 15 at intervals.

[0063] In one embodiment, if Figure 10 As shown, a light-emitting element 5 is further provided on the top cover 4. The light-emitting element 5 is electrically connected to the control module 8. The light-emitting element 5 is used to indicate different working states of the electronic hookah.

[0064] Specifically, when the user begins to puff on the electronic hookah, the light-emitting element 5 emits a bright, continuous blue or green light, clearly indicating that the device is in active use. When puffing stops and the device enters standby mode, the light-emitting element 5 changes to a slowly flashing red light, reminding the user that the device is ready but not currently in use. This lighting change not only enhances the user's interactive experience but also helps to intuitively understand the device's operating status. More specifically, when puffing stops, some of the uninhaled aerosol in the airway 3 escapes from the top cover 4, creating a smoky visual effect that complements the lighting effect, further enhancing the visual feedback and making the electronic hookah user experience more enjoyable and interesting.

[0065] In one embodiment, if Figure 10As shown, the light emitting element 5 is an LED lamp mounted on a circuit board.

[0066] In one embodiment, if Figure 10 As shown, the top cover 4 is further provided with a light guide 7, which is arranged around the outside of the light emitting element 5. The light guide 7 can scatter the light emitted by the light emitting element 5 and improve the light scattering rate.

[0067] In one embodiment, if Figure 10 As shown, the light guide 7 has a light incident surface and a light emitting surface. The light incident surface is arranged close to the light emitting component 5, and the light emitting surface is arranged back to the light emitting component 5. The light emitted by the light emitting component 5 enters the light guide 7 from the light incident surface, is scattered by the light guide 7, and is emitted from the light emitting surface.

[0068] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
