Description

Technical Field

[0001] This invention relates to the field of electronic atomization technology, and more specifically to an aerosol generating device that prevents the evaporation of atomizing liquid from damaging the host device. Background Technology

[0002] Aerosol generating devices can heat aerosol substrates and atomize them to produce aerosols. Currently, detachable aerosol generating devices mainly consist of an atomizer and a main unit for power supply, while integrated aerosol generating devices assemble the atomizing part and the power supply part on the same housing.

[0003] For disposable aerosol generators, the liquid storage component in the atomizer and the electronic components inside the main unit have interconnected vents. The liquid storage component is often located above the electronic components. Under different storage conditions, the liquid matrix stored inside the aerosol generator will evaporate to varying degrees. The evaporated particles can enter the main unit through the vents, affecting the reliability and lifespan of the internal electronic components, and even causing short circuits, thus seriously affecting the normal operation of the main unit. Summary of the Invention

[0004] To address the aforementioned shortcomings of existing technologies, this invention provides an aerosol generating device that prevents damage to the host unit from the evaporation of atomizing liquid. By utilizing the relative rotation of the host unit and the atomizer, and causing the spring needle to block the vent after movement, the liquid matrix can be prevented from evaporating into the host unit when not in use, thus avoiding damage to the electronic components inside the host unit.

[0005] Firstly, to solve the above-mentioned technical problems, the present invention aims to achieve this through the following technical solution: providing an aerosol generating device that prevents damage to the host unit from the evaporation of atomizing liquid, comprising an atomizer and a host unit rotatably connected to one end of the atomizer; the atomizer having a first electrode plate located at the center and a second electrode plate arranged around the first electrode plate at one end connected to the host unit; the atomizer also having a vent hole on the same circumference as the second electrode plate at one end; the host unit having a first spring pin located at the center and abutting against the first electrode plate and a second spring pin located on one side of the first spring pin and corresponding to the second electrode plate at one end; after the host unit rotates relative to the atomizer, the second spring pin connects to the second electrode plate and opens the vent hole, or the second spring pin disconnects from the second electrode plate and closes the vent hole.

[0006] Furthermore, the host unit is also provided with an air inlet that communicates with the vent.

[0007] Furthermore, the second electrode sheet has a ring-shaped structure and an opening, with the vent located at the opening.

[0008] Furthermore, the atomizer includes an upper shell, a liquid storage component disposed within the upper shell for containing a liquid matrix, an atomizing core disposed within the liquid storage component for atomizing the liquid matrix, and a base disposed within the upper shell for pressing against the liquid storage component. The first electrode plate, the second electrode plate, and the vent hole are all disposed on the base. The atomizing core is electrically connected to the first electrode plate and the second electrode plate respectively. The atomizing core communicates with the vent hole. One end of the main unit is rotatably connected to one end of the upper shell.

[0009] Furthermore, the liquid storage assembly includes a liquid storage chamber, a liquid storage component disposed within the liquid storage chamber for storing the liquid matrix, and an air guide tube disposed in the middle of the liquid storage component. The atomizing core is disposed within the air guide tube, and the air guide tube has a liquid guide hole for guiding the liquid matrix into the atomizing core.

[0010] Furthermore, the liquid storage chamber includes a hollow liquid storage tube and a first sealing element and a second sealing element disposed at both ends of the liquid storage tube for sealing. The two ends of the air guide tube are respectively fixed to the first sealing element and the second sealing element. The upper shell has a suction nozzle at one end away from the main unit that communicates with one end of the air guide tube. The other end of the air guide tube communicates with the vent hole.

[0011] Furthermore, a liquid suction element is provided on the outer surface of the first seal, located below the suction nozzle.

[0012] Furthermore, the atomizing core includes a liquid guiding component and a heating element disposed on the outer surface or inside the liquid guiding component. The heating element is provided with two conductive pins that are electrically connected to the first electrode plate and the second electrode plate, respectively.

[0013] The main unit further includes a lower shell, a fixing member disposed at one end of the lower shell, and a circuit board and a battery disposed inside the lower shell. The circuit board is electrically connected to the first spring pin, the second spring pin, and the battery, respectively. The circuit board is provided with a charging interface exposed outside the lower shell. The first spring pin and the second spring pin are both disposed on the fixing member. The air inlet is disposed on the lower shell. The fixing member is provided with a through hole connecting the vent hole and the air inlet hole. One end of the lower shell is inserted into the upper shell and rotatably connected to the upper shell.

[0014] Furthermore, the inner wall of the upper shell is provided with an annular groove, and one end of the outer wall of the lower shell is provided with a protruding annular buckle that engages with the annular groove.

[0015] The present invention has the following beneficial effects:

[0016] In this invention, the main unit and atomizer are first rotatably connected, and the second electrode plate is aligned with the vent hole on the same circumference. As the main unit or atomizer is rotated, the second spring pin rotates accordingly. In use, the second spring pin is rotated until it contacts the second electrode plate, thus misaligning the vent hole with the second spring pin to open the vent hole and allow gas flow for normal use. In non-use, the second spring pin is rotated to the vent hole position and blocked, causing the second electrode plate and the second spring pin to misalign and be in an open circuit state with the electrical connection disconnected. By blocking the vent hole with the spring pin, the airflow between the atomizer and the main unit is cut off, ensuring that the evaporation of the liquid matrix from the electrosol generating device does not flow into the main unit through the vent hole during transportation and storage after leaving the factory, thereby avoiding damage to the circuit board, battery, and other electronic components inside the main unit.

[0029] Example

[0030] like Figure 1-6As shown in the figure, this embodiment of an aerosol generating device for preventing damage to the host unit from atomizing liquid evaporation includes an atomizer 1 and a host unit 2 rotatably connected to one end of the atomizer 1. The atomizer 1 has a first electrode plate 10 at its center and a second electrode plate 11 surrounding the first electrode plate 10 at its end connected to the host unit 2. The atomizer 1 also has a vent hole 12 on the same circumference as the second electrode plate 11 at one end. The host unit 2 has a first spring pin 20 at its center and abutting against the first electrode plate 10, and a second spring pin 21 on one side of the first spring pin 20 and corresponding vertically to the second electrode plate 11 or the vent hole 12. The first electrode plate 10 and the first spring pin 20 are both centered, meaning that during the rotation of the atomizer or the host unit, the relative positions of the first electrode plate 10 and the first spring pin 20 do not change, maintaining a constant electrical connection. However, the relative positions of the second electrode plate 11, the vent hole 12, and the second spring pin 21 on one side will change, thereby utilizing… The rotational relationship allows the second spring pin 21 to align with the second electrode plate 11 or the vent 12, thus achieving different usage states. Specifically, when the main unit 2 rotates relative to the atomizer 1, and the second spring pin 21 is vertically aligned with the second electrode plate 11, the second spring pin 21 is misaligned with the vent 12, thereby opening the vent 12 to allow gas flow and normal use of the aerosol generator. Alternatively, when the second spring pin 21 is vertically aligned with the vent 12, the second spring pin 21 blocks the vent 12. In this case, the second spring pin 21 and the second electrode plate 11 are in a misaligned, open-circuit state, and the aerosol generator is unusable. By blocking the vent 12 with the second spring pin 21, the airflow between the atomizer 1 and the main unit 2 is cut off, ensuring that during transportation and storage after leaving the factory, the evaporation of the liquid matrix will not flow into the main unit 2 through the vent 12, thereby avoiding damage to the circuit boards, batteries, and other electronic components inside the main unit 2.

[0031] Understandably, in order to achieve better sealing effect and smooth sliding of the spring pin, the end of the vent hole 12 that contacts the spring pin is rounded, and the end of the second spring pin 21 that contacts the vent hole 12 is also rounded.

[0032] Preferably, the main unit 2 is also provided with an air inlet 22 that communicates with the vent 12. A mouthpiece 13 is provided at the end of the atomizer 1 away from the main unit 2. When in use, air is inhaled at the mouthpiece 13, creating a negative pressure inside. External air enters the main unit 2 through the air inlet 22 and then enters the atomizer 1 through the vent 12. After mixing with the aerosol generated by atomization in the atomizer 1, it flows out from the mouthpiece 13 and is inhaled by the user. In addition, a removable sealing piece 131 is inserted at the outer opening of the mouthpiece 13 to prevent the liquid matrix inside from evaporating and leaking out through the mouthpiece when it is not in use.

[0033] In one embodiment, the second electrode plate 11 is an annular structure and has an opening 111 to form an open annular structure, and the vent hole 12 is located in the middle of the opening 111, so that the second electrode plate 11 and the vent hole 12 are on the circumference and are used to cooperate with the second spring pin 21 respectively during rotation.

[0034] In one embodiment, the atomizer includes an upper shell 100, a liquid storage component disposed within the upper shell 100 for containing a liquid matrix, an atomizing core disposed within the liquid storage component for atomizing the liquid matrix, and a base 101 disposed within the upper shell 100 for pressing against the liquid storage component. A first electrode plate 10, a second electrode plate 11, and a vent 12 are all disposed on the base 101, wherein the first electrode plate 10 is located at the center of the base 101. The atomizing core is electrically connected to the first electrode plate 10 and the second electrode plate 11 respectively, so that after electrical conduction, the atomizing core is used to heat and atomize the liquid matrix. The two ends of the atomizing core are respectively connected to the vent 12 and the mouthpiece 13, so that the air entering the atomizer 1 can mix with the aerosol generated by atomization and flow out from the mouthpiece 13. One end of the main unit 2 is rotatably connected to one end of the upper shell 100, and the mouthpiece 13 is disposed in the upper shell 100 at the end away from the main unit 2.

[0035] Preferably, the liquid storage assembly includes a liquid storage chamber, a liquid storage component 14 disposed in the liquid storage chamber for storing liquid matrix, and an air guide tube 15 extending vertically through the liquid storage component 14. The atomizing core is disposed in the air guide tube 15, and the air guide tube 15 is provided with a liquid guide hole 151 for guiding the liquid matrix in the liquid storage component 14 into the atomizing core. One end of the air guide tube 15 is connected to the nozzle 13, and the other end is connected to the vent hole 12.

[0036] Preferably, the liquid storage chamber includes a hollow liquid storage tube 16 and a first sealing member 17 and a second sealing member 18 sealed at both ends of the liquid storage tube 16. The two ends of the air guide tube 15 are respectively fixed to the first sealing member 17 and the second sealing member 18. The liquid storage chamber forms a detachable structure, which facilitates the assembly and disassembly of the air guide tube 15 and the liquid storage member 14. A liquid suction member 19 is provided on the outer side of the first sealing member 17, located below the suction nozzle 13, for absorbing the condensate flowing back from the suction nozzle 13. The base 101 is located at the lower end of the second sealing member 18.

[0037] Preferably, the atomizing core includes a liquid guiding component 30 and a heating component 31 disposed on the outer surface or inside the liquid guiding component 30. The liquid guiding component 30 is used to draw the liquid matrix conducted through the liquid guiding hole 151, and the heating component 31 is used to heat and atomize the liquid matrix in the liquid guiding component 30. The liquid guiding component 30 can be made of cotton, fiber, porous ceramic, porous glass, etc., while the heating component 31 can be a heating wire, heating mesh, or heating film, etc. In this embodiment, the liquid guiding component 30 is a hollow cylindrical cotton column, and the heating element 31 is disposed on the inner surface of the liquid guiding component 30 so that the atomizing core is formed into a cylindrical atomizing core. In order to realize the connection between the heating element 31 and the electrode plate, two conductive pins 32 are provided on the heating element 31, which are respectively electrically connected to the first electrode plate 10 and the second electrode plate 11. Of course, the liquid guiding component can also be a block-shaped cotton sheet, with the bottom of the cotton sheet connected to the top of the liquid guiding component or located inside the liquid guiding component, and the heating element is disposed on the surface of the cotton sheet. Of course, there will be a gap between the cotton sheet and the air guiding tube to facilitate the passage of air.

[0038] In one embodiment, the main unit 2 includes a lower shell 23 with an internal cavity 200, a fixing member 24 located at one end of the lower shell 23 for sealing, and a circuit board 25 and a battery 26 located inside the lower shell 23. The circuit board 25 is electrically connected to the first spring pin 20, the second spring pin 21 and the battery 26, respectively, so that the battery 26 supplies power to the circuit board 25 and the atomizing core to achieve the purpose of heating and atomization. The circuit board 25 can also be used to control the on and off of the circuit. The circuit board 25 is provided with a charging interface 27 exposed outside the lower shell 23 for charging the battery 26. The first spring pin 20 and the second spring pin 21 are both located on the fixing member 24, wherein the first spring pin 20 is located at the center of the fixing member 24. The air inlet 22 is located at the bottom of the lower shell 23. One end of the lower shell 23 is inserted into the upper shell 100 at the end away from the mouthpiece 13 and is rotatably connected to the upper shell 100. In addition, the fixing member 24 is provided with a through hole 241 connecting the vent hole 12 and the air inlet 22.

[0039] Preferably, the inner wall of the upper shell 100 is provided with an annular groove 102, and one end of the outer wall of the lower shell 23 is provided with a protruding annular buckle 231 that engages with the annular groove 102. This annular structure allows the main unit to rotate 360 ​​degrees relative to the atomizer. The alignment of the second spring pin 21 with the air vent 12 is determined by the elastic stopping force and sound generated when the two align and abut against each other to seal the connection. The engaging structure also allows the upper and lower shells to form a single, connected unit. Of course, for convenience... To facilitate the alignment and simplify the operation of the second spring pin with the second electrode plate 11 and the vent 12, the annular groove can be modified into an arc-shaped groove. The buckle on the upper shell can rotate within the range of the arc-shaped groove, thereby limiting the rotation angle of the main unit 2 and the atomizer 1. When rotated to one end of the arc-shaped groove, the second spring pin 21 can be connected vertically to the second electrode plate 11. When rotated to the other end of the arc-shaped groove, the second spring pin 21 is vertically aligned with the vent 12 and blocks the vent.

[0040] Preferably, the main unit 2 also includes a microphone 28 located below the through hole 241 for sensing airflow.

[0041] In other embodiments, both the first and second seals are made of silicone.
