The terms "vertical", "horizontal", "upper", "lower", "left", "right" and similar expressions used herein are for illustrative purposes only and do not represent the only implementation.

[0041] Please refer to Figures 1 to 6 , this application provides an electronic atomization device, which includes an atomizer 1 and a battery assembly. The battery assembly is disposed on the bottom side of the atomizer 1 and is used to provide electrical energy for the atomizer 1.

[0042] The atomizer 1 includes a liquid storage member 10, an atomization tube 20, a heating member 80, a liquid guiding cotton 90, an atomization bracket 110, and a liquid blocking member 30. The liquid storage member 10 has a liquid storage cavity 11, and an air outlet hole 12 is provided at the top end of the liquid storage member 10. The atomization tube 20 is assembled in the liquid storage cavity 11, and the atomization tube 20 has an atomization channel 21 therein. A liquid guiding hole 22 is provided on the atomization tube 20, and the liquid guiding hole 22 communicates between one end of the atomization channel 21 and the liquid storage cavity 11. The other end of the atomization channel 21 away from the liquid guiding hole 22 communicates with the air outlet hole 12. The liquid blocking member 30 is located in the liquid storage cavity 11 and is installed outside the atomization tube 20. The liquid blocking member 30 has a first position for closing the liquid guiding hole 22 and a second position for opening the liquid guiding hole 22 relative to the atomization tube 20, and the liquid blocking member 30 is switched between the first position and the second position under the action of an external force. The heating member 80, the liquid guiding cotton 90, and the atomization bracket 110 are all located inside one end of the atomization tube 20 where the liquid guiding hole 22 is provided. The liquid guiding cotton 90 is arranged circumferentially around the heating member 80, and the atomization bracket 110 is arranged circumferentially around the liquid guiding cotton 90. A liquid inlet hole 1101 is provided on the atomization bracket 110. When the liquid blocking member 30 opens the liquid guiding hole 22, the aerosol-forming matrix in the liquid storage cavity 11 and the liquid adsorbed on the liquid guiding cotton 90 through the liquid guiding hole 22 and the liquid inlet hole 1101. When the heating member 80 is electrically connected to the power supply assembly and the power supply assembly supplies power to the heating member 80, the heating member 80 atomizes the aerosol-forming matrix on the liquid guiding cotton 90 to form an aerosol and outputs it through the atomization channel 21.

[0043] Wherein, the liquid guiding hole 22 on the atomization tube 20 can be one or more. If there are multiple liquid guiding holes 22, all the liquid guiding holes 22 are arranged at intervals along the circumferential direction of the atomization tube 20.

[0044] A liquid injection hole 13 is also provided on the liquid storage member 10. The liquid injection hole 13 and the air outlet hole 12 can both be provided on the top end face of the liquid storage member 10, or the air outlet hole 12 is provided on the top end face of the liquid storage member 10, and the liquid injection hole 13 is provided on the side wall of the liquid storage member 10, which can be specifically set according to requirements.

[0045] Specifically, the external force for driving the liquid blocking member 30 to switch between the first position and the second position can come from an electric driving structure, a mechanical driving structure, or other driving components. For example, a waterproof and aerosol-forming matrix-proof motor can be designed in the liquid storage cavity 11, and the motor drives the liquid blocking member 30 to move and switch positions.

[0046] As an example, the first position and the second position can be arranged in sequence along the axial direction of the atomization tube 20. Taking the state of the atomizer 1 as an example, the liquid blocking member 30 realizes position switching by moving up and down. As an example, the first position and the second position can also be arranged in sequence along the radial direction of the atomization tube 20. Taking the state of the atomizer 1 as an example, the liquid blocking member 30 realizes position switching by moving left and right. Figure 5 Taking the state of the atomizer 1 as an example, the liquid blocking member 30 realizes position switching by moving up and down. As an example, the first position and the second position can also be arranged in sequence along the radial direction of the atomization tube 20. Taking the state of the atomizer 1 as an example, the liquid blocking member 30 realizes position switching by moving left and right. Figure 5 Taking the state of the atomizer 1 as an example, the liquid blocking member 30 realizes position switching by moving left and right.

[0047] Of course, in some other embodiments, the liquid blocking member 30 can achieve position switching through other driving methods and other movement methods, and specific details are not limited herein.

[0048] During the process of injecting and replenishing the aerosol generating matrix into the liquid storage cavity 11, the liquid blocking member 30 switches to the first position, and the liquid blocking member 30 closes the liquid guiding hole 22 to prevent the aerosol generating matrix stored in the liquid storage cavity 11 from entering the atomization channel 21 through the liquid guiding hole 22, thereby avoiding the occurrence of leakage of the aerosol generating matrix and providing a good user experience. After the replenishment of the aerosol generating matrix is completed, the liquid blocking member 30 switches to the second position, and the liquid blocking member 30 opens the liquid guiding hole 22 to allow the aerosol generating matrix stored in the liquid storage cavity 11 to enter the atomization tube 20 through the liquid guiding hole 22 and supply the aerosol generating matrix to the liquid guiding cotton 90, so as to enable the normal atomization operation of the electronic atomization device.

[0049] Please refer to Figure 3 、 Figure 5 and Figure 6 In some alternative embodiments of the present application, the liquid blocking member 30 is sleeved outside the atomization tube 20, and the liquid blocking member 30 slides axially along the atomization tube 20 under the action of an external force and switches between the first position and the second position. The atomization tube 20 can guide the sliding of the liquid blocking member 30, thereby ensuring the stability of the sliding of the liquid blocking member 30.

[0050] In some alternative embodiments of the present application, the atomizer 1 further includes a mouthpiece 40 and a magnetic attraction member 50. The mouthpiece 40 has an air outlet channel 41 therein, and the magnetic attraction member 50 is installed on the mouthpiece 40. When the mouthpiece 40 is sleeved outside the top end of the liquid storage member 10, the air outlet hole 12 is communicated with the air outlet channel 41, and the liquid blocking member 30 moves from the first position to the second position under the magnetic attraction force provided by the magnetic attraction member 50; when the mouthpiece 40 is disassembled, the liquid blocking member 30 moves from the second position to the first position under the action of gravity.

[0051] Among them, the mouthpiece 40 can be detachably connected to the liquid storage member 10 by means of buckling, screwing, etc.

[0052] The liquid blocking member 30 is made of a metal material containing iron.

[0053] When the mouthpiece 40 is sleeved outside the top end of the liquid storage member 10, the magnetic attraction force provided by the magnetic attraction member 50 drives the liquid blocking member 30 to move from the first position to the second position to open the liquid guiding hole 22. In this way, the aerosol generating matrix in the liquid storage cavity 11 can be smoothly supplied to the liquid guiding cotton 90, thereby ensuring the normal progress of atomization. Furthermore, the aerosol formed by atomization can be smoothly output to the outside through the air outlet hole 12 and the air outlet channel 41.

[0054] When the nozzle 40 is detached from the liquid storage member 10, the liquid blocking member 30 moves from the second position to the first position under the action of gravity and closes the liquid guiding hole 22. At this time, the atomizer 1 stops atomizing, and the user can replenish the aerosol-forming substrate into the liquid storage chamber 11 through the liquid injection hole 13 on the liquid storage member 10.

[0055] The method of driving the position switching of the liquid blocking member 30 through magnetic suction force and gravity is beneficial to simplifying the structure of the atomizer 1 and reducing the manufacturing cost of the atomizer 1. In addition, the method of driving the position switching of the liquid blocking member 30 through magnetic suction force and gravity is a mechanical driving method, and this method does not consume electric energy, so it can also reduce the energy consumption during the use of the atomizer 1.

[0056] Further, in some alternative embodiments, the liquid blocking member 30 includes an opening and closing portion 31 and a flanging portion 32 connected thereto. The opening and closing portion 31 is used to open or close the liquid guiding hole 22. The flanging portion 32 is folded outward relative to the opening and closing portion 31 and is disposed closer to the air outlet hole 12 than the opening and closing portion 31. The flanging portion 32 is configured to be oppositely disposed relative to the magnetic attracting member 50 in a direction parallel to the axial direction of the atomizing tube 20 when the nozzle 40 is sleeved outside the top end of the liquid storage member 10.

[0057] Among them, the opening and closing portion 31 extends along the axial direction of the atomizing tube 20 and is the main part of the liquid blocking member 30 that is guided by the atomizing tube 20 to slide.

[0058] Generally, the magnetic attracting member 50 is generally disposed on one side in the radial direction of the air outlet hole 12. In order to reduce the occupied space of the liquid blocking member 30 in the liquid storage chamber 11 and increase the storage amount of the aerosol-forming substrate in the liquid storage chamber 11, the opening and closing portion 31 is provided with a thin-wall structure, which easily causes the opening and closing portion 31 and the magnetic attracting member 50 to be unable to be oppositely disposed in the direction parallel to the axial direction of the atomizing tube 20, thereby resulting in a weak magnetic suction force and the liquid blocking member 30 being unable to switch from the first position to the second position. However, in the present application, by providing the flanging portion 32, the flanging portion 32 is folded outward and extended relative to the opening and closing portion 31. Therefore, in the direction parallel to the axial direction of the atomizing tube 20, the projection of the magnetic attracting member 50 can fall into the folded portion as much as possible, ensuring the reliability of magnetic attraction.

[0059] In some alternative embodiments of the present application, there are at least two magnetic attracting members 50, and all the magnetic attracting members 50 are disposed along the circumferential direction of the atomizing tube 20. The cooperation of multiple magnetic attracting members 50 has a stronger magnetic suction force. Therefore, when the nozzle 40 is installed on the liquid storage member 10, the liquid blocking member 30 can be driven by the magnetic suction force and switched from the first position to the second position.

[0060] Please refer to again Figure 5 and Figure 6, in some alternative embodiments of the present application, a liquid injection hole 13 is provided at the top end of the liquid storage member 10. The liquid injection hole 13 communicates with the liquid storage cavity 11. When the suction nozzle 40 is sleeved outside the top end of the liquid storage member 10, the magnetic member 50 is arranged towards the liquid injection hole 13, and the liquid blocking member 30 is exposed to the liquid injection hole 13.

[0061] Specifically, both the liquid injection hole 13 and the air outlet hole 12 are provided on the top surface of the liquid storage member 10. When the suction nozzle 40 is sleeved outside the top end of the liquid storage member 10, the liquid injection hole 13 is blocked by the suction nozzle 40 to reduce the risk of external dust and debris entering the liquid storage cavity 11 through the liquid injection hole 13.

[0062] In addition, when the suction nozzle 40 is sleeved outside the top end of the liquid storage member 10, the magnetic member 50 is arranged towards the liquid injection hole 13, and the liquid blocking member 30 is exposed to the liquid injection hole 13. Therefore, the magnetic member 50 and the liquid blocking member 30 can be aligned in the axial direction of the parallel atomization tube 20, and there is no blockage of the liquid blocking member 30 between the magnetic member 50 and the liquid blocking member 30. The magnetic attraction force can stably and reliably drive the liquid blocking member 30 to move from the first position to the second position to open the liquid guiding hole 22.

[0063] Combined with Figure 4 、 Figure 5 and Figure 6 , in some alternative embodiments of the present application, a limiting groove 42 is provided on the suction nozzle 40. When the suction nozzle 40 is sleeved outside the top end of the liquid storage member 10, the notch of the limiting groove 42 is arranged towards the liquid injection hole 13, and the magnetic member 50 is limited in the limiting groove 42. Among them, the limiting grooves 42 correspond to the magnetic members 50 one by one, and each magnetic member 50 is limited in the corresponding limiting groove 42. The setting of the limiting groove 42 facilitates the installation of the magnetic member 50 and improves the installation efficiency.

[0064] In some alternative embodiments of the present application, the atomizer 1 further includes a first sealing seat 60, and the first sealing seat 60 is used to at least seal the gap between the top surface of the liquid storage member 10 where the liquid injection hole 13 and the air outlet hole 12 are provided and the suction nozzle 40. In this way, after the suction nozzle 40 is installed on the liquid storage member 10, the risk that the aerosol-forming matrix leaks to the outside through the liquid injection hole 13, the gap between the top surface of the liquid storage member 10 and the suction nozzle 40, or through the liquid injection hole 13, the gap between the top surface of the liquid storage member 10 and the suction nozzle 40, and the air outlet channel 41 can be reduced, thereby improving the reliability of the atomizer 1 during operation.

[0065] In some alternative embodiments of the present application, the liquid storage member 10 includes a base 14 and a liquid storage cover 15. The liquid storage cover 15 covers the base 14 and defines a liquid storage cavity 11 with the base 14. An air outlet hole 12 is provided on the top surface of the liquid storage cover 15 away from the base 14. An installation hole 141 is formed on the base 14, and a part of the atomization tube 20 extends into the installation hole 141. The atomizer 1 further includes a second sealing seat 70. The second sealing seat 70 is arranged in the liquid storage cavity 11 and is used to seal the gap between the base 14 and the liquid storage cover 15, as well as the gap between the atomization tube 20 and the base 14.

[0066] Specifically, the first sealing seat 60 and the second sealing seat 70 can both be rubber seats, silicone seats or other sealing seat structures.

[0067] Wherein, the connection between the base 14 and the liquid storage cover 15 is detachable. When the base 14 is disassembled, it is convenient to load the atomization tube 20, the liquid blocking member 30, etc. into the liquid storage cover 15. When the base 14 is connected to the liquid storage cover 15, the opening at one end of the liquid storage cover 15 away from the air outlet hole 12 can be closed to define the liquid storage cavity 11.

[0068] As for the second sealing seat 70 being sealed in the gap between the base 14 and the liquid storage cover 15, as well as the gap between the atomization tube 20 and the base 14, it can reduce the risk of the aerosol-forming matrix leaking to the outside through the above gaps, and further improve the reliability of the operation of the atomizer 1.

[0069] In some alternative embodiments of the present application, the liquid storage member 10 further includes a guiding tube 16. The guiding tube 16 is located in the liquid storage cavity 11 and is arranged around the circumference of the air outlet hole 12. One end of the atomization tube 20 away from the liquid guiding hole 22 is clamped in the guiding tube 16. Therefore, the installation hole 141 and the guiding tube 16 cooperate to realize the installation and positioning of the atomization tube 20, making the installation of the atomization tube 20 simple and convenient.

[0070] During the process of injecting and replenishing the aerosol-forming matrix into the liquid storage cavity 11 of the above-mentioned atomizer 1 and the electronic atomization device, the liquid blocking member 30 switches to the first position, and the liquid blocking member 30 closes the liquid guiding hole 22 to prevent the aerosol-forming matrix stored in the liquid storage cavity 11 from entering the atomization channel 21 through the liquid guiding hole 22, thus preventing the occurrence of the aerosol-forming matrix leakage, and the user experience is good. After the replenishment of the aerosol-forming matrix is completed, the liquid blocking member 30 switches to the second position, and the liquid blocking member 30 opens the liquid guiding hole 22 to allow the aerosol-forming matrix stored in the liquid storage cavity 11 to enter the atomization tube 20 through the liquid guiding hole 22 and supply the aerosol-forming matrix to the liquid guiding cotton 90, so as to realize the normal atomization operation of the electronic atomization device.

[0071] The technical features of the above-described embodiments can be combined arbitrarily. For the sake of brevity of description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as within the scope described in this specification.

[0072] The above-described embodiments merely represent several implementation manners of the present application. The description is relatively specific and detailed, but it should not be construed as a limitation on the scope of the patent application. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present application, several deformations and improvements can still be made, and these all belong to the protection scope of the present application. Therefore, the protection scope of the patent of the present application shall be subject to the appended claims.
