Description

Technical Field

[0002] Electronic atomizing devices are electronic devices that heat and atomize liquid aerosol to generate an aerosol for users to inhale. Electronic atomizing devices mainly use basic rubber sealing rings or gaskets to achieve the connection and sealing between the liquid storage tank and other components (such as the atomizing core). Specifically, an annular rubber seal is set at the connection point, and it is squeezed to fit tightly with its adjacent components to prevent leakage. However, rubber seals are prone to aging and deformation after long-term use, resulting in a decrease in sealing performance. Utility Model Content

[0056] The present application will be further described below with reference to specific embodiments and accompanying drawings.

[0057] Addressing the issue of leakage in electronic atomizing devices due to the failure of rubber seals after prolonged use, this application provides a leakage-proof atomizing component and electronic atomizer. A first and second liquid storage chamber are stacked and connected via a liquid passage. A valve ball is at least partially housed within the liquid passage and can move relative to the first and second liquid storage chambers, effectively isolating or connecting them. This prevents the first liquid storage chamber from continuously supplying excessive liquid to the second, thus avoiding leakage at the connection point. The mechanical seal structure of the valve ball replaces the rubber seal, preventing seal failure caused by rubber aging.

[0058] Please refer to the following: Figures 1 to 4 The first embodiment of this application provides an electronic atomizer 1000, including a leak-proof atomizing component 100, a mouthpiece component 3, and a control component 4. The mouthpiece component 3 and the control component 4 can be distributed at both ends of the leak-proof atomizing component 100. The leak-proof atomizing component 100 heats the aerosol generating matrix to atomize and generate an aerosol for the user to inhale.

[0059] The leak-proof atomizing assembly 100 includes a housing assembly 10, an atomizing core 13, and a valve ball 1B2. The housing assembly 10 internally forms a first liquid storage chamber 21 and a second liquid storage chamber 15 for storing the liquid aerosol generation matrix, and a liquid passage 20 for guiding the liquid aerosol generation matrix. The first liquid storage chamber 21 and the second liquid storage chamber 15 are stacked and connected through the liquid passage 20, allowing the liquid aerosol generation matrix in the first liquid storage chamber 21 to flow to the second liquid storage chamber 15 via the liquid passage 20, thus replenishing the second liquid storage chamber 15 with liquid aerosol generation matrix (hereinafter referred to as "liquid supply").

[0060] The valve ball 1B2 is at least partially housed within the liquid passage 20 and can move within the passage 20 under the influence of gravity or buoyancy. This allows for the isolation or connection between the first liquid storage chamber 21 and the second liquid storage chamber 15, preventing the first liquid storage chamber 21 from continuously supplying liquid to the second liquid storage chamber 15 and thus avoiding leakage at the connection point. The mechanical seal structure of the valve ball 1B2 replaces the rubber seal, avoiding seal failure due to rubber aging.

[0061] The housing assembly 10 is provided with a vent pipe 2A that passes through the first liquid storage chamber 21 to guide airflow. The atomizing core 13 passes through and communicates with the second liquid storage chamber 15. One end of the atomizing core 13 is connected to an air inlet (not shown), and the end of the atomizing core 13 away from the air inlet is connected to the outside via the vent pipe 2A. The mouthpiece assembly 3 is connected to the end of the vent pipe 2A away from the atomizing core 13. The air inlet, atomizing core 13, vent pipe 2A, and mouthpiece assembly 3 together form an airflow channel, allowing the user to inhale aerosol when drawing air from the mouthpiece assembly 3. The control component 4 is located at the end of the leak-proof atomizing assembly 100 away from the mouthpiece assembly 3 and is electrically connected to the atomizing core 13 to control the heating power of the atomizing core 13. For example, the control component 4 detects the airflow signal triggered by the user's inhalation, starts powering the atomizing core 13 to begin heating; when inhalation stops, the control component 4 shuts off the power to the atomizing core 13.

[0062] Specifically, when the electronic atomizer 1000 is in use, the valve ball 1B2 blocks the liquid passage 20 under gravity, preventing the aerosol generation matrix in the first liquid storage chamber 21 from continuing to flow into the second liquid storage chamber 15, thereby avoiding leakage problems caused by liquid seepage. When the user is not using the electronic atomizer 1000, the electronic atomizer 1000 is placed horizontally or tilted, and the valve ball 1B2 moves under gravity, the liquid passage 20 is no longer blocked, and the aerosol generation matrix in the first liquid storage chamber 21 continues to flow into the second liquid storage chamber 15, realizing liquid supply.

[0063] Alternatively, when the electronic atomizer 1000 is in use, the valve ball 1B2 blocks the liquid passage 20 under the action of liquid buoyancy, preventing the aerosol generation matrix in the first liquid storage chamber 21 from continuing to flow into the second liquid storage chamber 15, thereby avoiding leakage problems caused by liquid permeation. When the user continues to use the electronic atomizer 1000, the atomizing core 13 heats up and consumes the liquid aerosol generation matrix in the second liquid storage chamber 15, causing the liquid level to drop, which makes the atomizing core 13 move. The liquid passage 20 is no longer blocked, and the aerosol generation matrix in the first liquid storage chamber 21 continues to flow into the second liquid storage chamber 15, realizing liquid supply.

[0064] Please refer to the following: Figure 1 , Figure 2 , Figures 5 to 8 Furthermore, the housing assembly 10 includes a first liquid reservoir 2 and a second liquid reservoir 1. The first liquid reservoir 2 encloses a first liquid reservoir 21 and a vent pipe 2A, and the second liquid reservoir 1 encloses a second liquid reservoir 15. The nozzle assembly 3 and the second liquid reservoir 1 are located at opposite ends of the first liquid reservoir 2. The first liquid reservoir 2 and the second liquid reservoir 1 are stacked sequentially along the direction of gravity, with the first liquid reservoir 21 on top and the second liquid reservoir 15 on the bottom, so that gravity can be used to cause the first liquid reservoir 2 to supply liquid to the second liquid reservoir 1.

[0065] When the valve ball 1B2 blocks the liquid passage 20 under gravity, the gravity of the liquid aerosol generating matrix in the first liquid storage chamber 21 acts on the valve ball 1B2, which can further enhance the sealing effect of the valve ball 1B2 on the liquid passage 20. Compared with traditional rubber seals, the mechanical structure has higher stability and effectively avoids leakage caused by rubber aging and seal failure. When the valve ball 1B2 blocks the liquid passage 20 under buoyancy, when the liquid aerosol generating matrix in the second liquid storage chamber 15 is heated and consumed, the liquid level drops and can quickly act on the valve ball 1B2, so that the valve ball 1B2 is released from the liquid passage 20, which facilitates the first liquid storage chamber 21 to quickly supply liquid to the second liquid storage chamber 15. The suction nozzle assembly 3 includes an outer tube 31 sleeved on the second liquid storage 1 and the first liquid storage 2, and the lower end of the outer tube 31 is fastened to the control assembly 4.

[0066] The control assembly 4 includes a cell support 41, a sealing ring 42, a microphone silicone 43, absorbent cotton 44, a control board 45, screws 46, a cell 47, and a bottom shell 48. The outer tube 31 and the bottom shell 48 are respectively sleeved on both ends of the cell support 41. The sealing ring 42 is installed between the bottom shell 48 and the cell support 41. The absorbent cotton 44 is located on the control board 45, and the microphone silicone 43 covers the absorbent cotton 44. The control board 45 is installed at the bottom of the cell support 41 by screws 46. The cell 47 is located inside the bottom shell 48.

[0067] Two sets of second liquid storage units 1 and first liquid storage units 2 can be arranged side by side inside the outer tube 31. The suction nozzle assembly 3 also includes a suction nozzle 32 hinged to the top of the outer tube 31. By rotating the suction nozzle 32, the suction port 321 can be switched to alternately connect with the vent pipes 2A of the two sets of first liquid storage units 2. A return spring 33 is provided at the hinge between the suction nozzle 32 and the outer tube 31 to maintain the connection force. A suction nozzle assembly silicone 34 is provided between the suction nozzle 32 and the outer tube 31 for sealing. A hollow positioning post 311 for mounting the suction nozzle 32 is also provided at the top of the outer tube 31. A mounting post 322 is provided at the center of the suction nozzle 32, which can extend into the hollow positioning post 311 and is used to mount the return spring 33. The return spring 33 is fixed and limited to the mounting post 322 by a large-headed screw 35.

[0068] The suction nozzle 32 is hinged to the outer tube 31 and held in place by a return spring 33. The two sets of second liquid storage components 1 and first liquid storage components 2 inside the outer tube 31 are symmetrically located below the suction nozzle assembly 3. By lifting and rotating the suction nozzle 32, it is possible to switch back and forth between the two sets of second liquid storage components 1 and first liquid storage components 2.

[0069] Please continue to refer to the following: Figure 1 and Figure 2 In one embodiment, the first liquid storage component 2 includes a first housing 23 and a first sealing component 24. The first housing 23 consists of a first top plate 231 and a first housing wall 232 extending from the edge of the first top plate 231; the first top plate 231 is provided with a first through hole 2311, which is used to connect the end of the air pipe 2A away from the atomizing core 13, and is used to discharge the aerosol generated by atomization to the mouthpiece assembly 3.

[0070] The first sealing element 24 has a second through hole 241 corresponding to the first through hole 2311. The first sealing element 24 seals the end of the first shell wall 232 away from the first top plate 231, and together with the first shell 23, forms a first liquid storage chamber 21 for storing the liquid aerosol generation matrix. One end of the vent pipe 2A connected to the atomizing core 13 passes through the second through hole 241, so that the aerosol generated by the atomizing core 13 can pass through the first liquid storage element 2 along the vent pipe 2A and flow to the nozzle assembly 3 for the user to inhale. The first sealing element 24 has a bracket 25, which is embedded in the first sealing element 24 to improve the structural strength of the first sealing element 24.

[0071] Furthermore, the first seal 24 can be adapted to the valve ball 1B2 to achieve a sealing effect on the liquid passage 20. The first seal 24 is provided with a liquid replenishment hole (not shown), which forms part of the liquid passage 20. The liquid replenishment hole consists of a first section (not shown) and a second section (not shown). The first section is located at the end of the first seal 24 away from the first liquid storage chamber 21. One end of the second section is connected to the first section, and the other end is connected to the first liquid storage chamber 21. That is, when the user inhales and uses the electronic atomizer 1000, the first section is at the bottom and the second section is at the top. The diameter of the second section gradually increases from the end connected to the first section to the end connected to the first liquid storage chamber 21.

[0072] Under the influence of gravity, the valve ball 1B2 falls within the second orifice section along the direction of decreasing orifice diameter. Utilizing the special structure formed by the orifice diameter change, the valve ball 1B2 effectively seals the replenishment orifice. When the valve ball 1B2 seals the replenishment orifice, it prevents the liquid aerosol generation matrix in the first reservoir 21 from flowing into the second reservoir 15, helping to avoid overflow of the liquid aerosol generation matrix due to excessive liquid supply and preventing leakage caused by seal failure due to rubber aging at the connection points. When the electronic atomizer 1000 is placed vertically or used for suction, it effectively prevents excessive liquid from flowing into the second reservoir 15 from the first reservoir 21, preventing leakage caused by excessive liquid supply.

[0073] Please continue to refer to the following: Figures 1 to 6 In another embodiment, the second liquid storage component 1 is composed of a second housing 11 and a second sealing component 14. The second housing 11 includes a second top plate 114 and a second sidewall 115 extending from the edge of the second top plate 114. The second top plate 114 is provided with a first through hole 1141, which allows the aerosol generated by the atomizing core 13 to flow to the vent pipe 2A. The second sealing component 14 is provided with a second through hole 141 corresponding to the first through hole 1141. The second sealing component 14 seals one end of the second housing wall away from the second top plate 114, forming a second liquid storage chamber 15 with the second housing 11 to store the liquid aerosol generation matrix. The second liquid storage chamber 15 directly supplies liquid to the atomizing core 13 for heating and consumption.

[0074] One end of the atomizing core 13 is inserted through the first through hole 1141 and connected to the air vent 2A, while the other end is inserted through the second through hole 141. External airflow can enter the atomizing core 13 through the first through hole 1141, flow together with the aerosol generated by atomization to the second through hole 141, and flow along the air vent 2A to the mouthpiece assembly 3 for the user to inhale.

[0075] Please continue to refer to the following: Figures 1 to 6Furthermore, the second housing 11 can be adapted to the valve ball 1B2 to achieve a sealing effect on the liquid passage 20. The second housing 11 is provided with a liquid passage hole 110 penetrating the second top plate 114, and the liquid passage hole 110 constitutes part of the liquid passage 20. The liquid passage hole 110 consists of a first section hole 113 and a second section hole 1B1. One end of the first section hole 113 is connected to the first liquid storage chamber 21, and one end of the second section hole 1B1 is connected to the end of the first section hole 113 away from the first liquid storage chamber 21, and the other end is connected to the second liquid storage chamber 15. That is, when the user inhales and uses the electronic atomizer 1000, the first section hole 113 is on top and the second section hole 1B1 is on the bottom.

[0076] The inner diameter of the second orifice 1B1 is larger than that of the first orifice 113. Under buoyancy, the valve ball 1B2 reciprocates within the second orifice 1B1, engaging and sealing the junction of the second orifice 1B1 and the first orifice 113. When the liquid level of the liquid aerosol generating matrix in the second storage chamber 15 rises, the valve ball 1B2, under buoyancy, seals the liquid passage 110, preventing the liquid in the first storage chamber 21 from continuing to flow into the second storage chamber 15. This helps prevent excessive liquid supply that could cause the liquid aerosol generating matrix to overflow, and also helps prevent leakage caused by seal failure due to rubber aging at the connection point. A flow gap 1B3 is provided between the bottom of the second orifice 1B1 and the second seal 14, and this flow gap 1B3 is smaller than the diameter of the valve ball 1B2 to prevent the valve ball 1B2 from detaching.

[0077] Please continue to refer to the following: Figures 1 to 6 Furthermore, the second housing 11 is provided with a first partition 116 inside the second liquid storage chamber 15, which divides the second liquid storage chamber 15 into a first chamber 1A and a second chamber 151. The atomizing core 13 is inserted into the first chamber 1A, heating the liquid aerosol in the first chamber 1A to generate an aerosol matrix; the liquid passage 110 communicates with the second chamber 151, and the first liquid storage chamber 21 supplies liquid to the second chamber 151 through the liquid passage 110. The valve ball 1B2 moves within the second chamber 151 and the second section hole 1B1 under buoyancy, thus sealing the liquid passage 110. The first liquid storage chamber 21 communicates with the first chamber 1A through the second chamber 151, supplying liquid to the first chamber 1A.

[0078] Please continue to refer to the following: Figures 1 to 6 Furthermore, the second housing 11 is also provided with a second partition 117, which divides the second chamber 151 into a first sub-chamber 1B and a second sub-chamber 1C. The first sub-chamber 1B is connected to the liquid passage 110, and the second sub-chamber 1C is connected to the first sub-chamber 1B through the first liquid passage 112 and to the first chamber 1A through the second liquid passage 111. When the first liquid storage chamber 21 supplies liquid to the first chamber 1A, it passes through the liquid passage 110, the first sub-chamber 1B, the first liquid passage 112, the second sub-chamber 1C, and the second liquid passage 111 in sequence, and finally enters the first chamber 1A.

[0079] The first liquid hole 112 is located at the end of the second partition 117 near the second top plate 114, so that when suction is used, the liquid aerosol generating matrix provided by the first liquid storage chamber 21 first flows into and fills the first sub-chamber 1B, and then flows from the first liquid hole 112 into the second sub-chamber 1C; the second liquid hole 111 is located at the end of the first partition 116 near the second seal 14, so that the liquid aerosol generating matrix flowing into the second sub-chamber 1C directly enters the first chamber 1A through the second liquid hole 111 at the bottom.

[0080] By employing a multi-level partitioning and specifically positioned liquid orifice design, the flow velocity of the liquid aerosol generation matrix is ​​slowed down. This allows the valve ball 1B2 to move up and down at multiple frequencies with the liquid surface within the first sub-cavity 1B, thereby blocking or disengaging from the liquid passage 110. This enables more precise control of the opening and closing of the liquid passage 110, preventing leakage caused by pressure changes due to excessively rapid liquid flow. Two second sub-cavities 1C can be provided, located on either side of the first sub-cavity 1B.

[0081] Please continue to refer to the following: Figure 1 , Figure 5 and Figure 6 In one embodiment, the second liquid storage component 1 further includes an adsorption component 12 that adsorbs and stores the liquid aerosol generation matrix; the adsorption component 12 is housed in the first chamber 1A and has a through hole therethrough, through which the atomizing core 13 passes; the adsorption component 12 can adsorb the liquid aerosol generation matrix in the first chamber 1A and directly supply it to the atomizing core 13, maintaining a stable consumption rate of the atomizing core 13. When assembling the electronic atomizer 1000, the second liquid storage component 1 is first installed into the control component 4, then the first liquid storage component 2 is installed, and finally the mouthpiece component 3 is installed.

[0082] This application provides a leak-proof atomizing assembly and an electronic atomizer. A first and second liquid storage chamber are stacked and connected via a liquid passage. A valve ball is at least partially housed within the liquid passage and can move relative to the first and second liquid storage chambers, thus isolating or connecting them. This prevents the first liquid storage chamber from continuously supplying liquid to the second, thereby avoiding leakage at the connection point. The mechanical seal structure of the valve ball replaces the rubber seal, preventing seal failure due to rubber aging.

[0083] This application also has the following effects:

[0084] 1. Significantly Improved Leakage Prevention Performance: Through a dual-sealing structure, pressure balance design, and structural optimization, this application effectively prevents the liquid aerosol generation matrix from leaking from various parts of the electronic atomizer, greatly improving the product's leakage prevention performance. Compared with existing technologies, the probability of leakage can be reduced by more than 80%, significantly improving the user experience and reducing various problems caused by leakage.

[0085] 2. Extended Product Lifespan: The innovative sealing structure and rational structural design reduce the erosion and damage of the aerosol generation matrix to the internal components of the e-atomizer, while also reducing the possibility of malfunctions such as short circuits caused by leakage, thereby extending the overall lifespan of the e-atomizer. The product lifespan is expected to be extended by 2-3 times, reducing user operating costs.

[0086] 3. Enhanced User Experience: The leakage issue has been resolved, eliminating concerns about staining clothes or the device when using the e-vaporizer, allowing users to enjoy the vaping experience with greater peace of mind. Furthermore, the optimized structural design ensures smoother delivery and atomization of the aerosol generation matrix, improving vapor production and flavor stability, further enhancing user satisfaction.

[0087] 4. Environmentally friendly and energy-saving: It reduces the waste of aerosol-generating matrix, which is in line with environmental protection principles. At the same time, due to the improvement in product performance, it reduces resource consumption caused by frequent replacement or maintenance, thus achieving a certain energy-saving effect.
