Description

Technical Field

[0002] An electronic atomization device is a device that heats the aerosol matrix through an atomization core so that the heated aerosol matrix is ​​atomized to generate an aerosol for the user to inhale. An electronic atomization device usually includes an atomizer and a power supply control module. The atomizer includes an atomization core, a nozzle, a liquid storage tank, and an aerosol matrix contained in the liquid storage tank; the power supply control module includes a battery, a control circuit board, etc., which is used to supply power to the atomization core and control the start and stop of the atomization core.

[0003] Due to the influence of usage status, long-distance transportation, regulations and other factors, the volume of the original aerosol matrix in the electronic atomization device is often limited, resulting in a small number of puffs that can be sucked by the electronic atomization device reagent, which is a poor experience for users. In this regard, the prior art has a method of supplementing the aerosol matrix by adding a liquid storage tank to increase the number of puffs. As for adding a liquid storage tank, it is connected to the original liquid storage tank in the atomizer that directly supplies the aerosol matrix to the atomization core by setting a second liquid storage tank, and based on the gravity of the aerosol matrix itself, the aerosol matrix contained in the second liquid storage tank moves to the first liquid storage tank located below it, because the second liquid storage tank and the first liquid storage tank are both sealed warehouses, and the aerosol matrix liquid has a certain viscosity.

[0050] See also Figure 1-4 As shown, the present application provides a nebulizer 100, which includes a main body 10 and a liquid storage unit 20. The liquid storage unit 20 is detachably connected to the main body 10 and is configured to form a second liquid storage tank 21, which is used to contain an aerosol matrix.

[0051] Furthermore, the main body 10 includes an atomizing core 11, an atomizing channel and a first liquid storage tank 13. The atomizing core 11 is disposed in the atomizing channel and is used to heat the aerosol substrate supplied from the first liquid storage tank 13, so that the heated aerosol substrate is atomized to generate aerosol, and flows out of the atomizer 100 from the atomizing channel.

[0052] See also Figure 3-4 As shown, the main body 10 is also structured to form a liquid guiding channel 1512, an air storage bin 14 and an air guiding channel 1514. The liquid guiding channel 1512 is connected between the second liquid storage bin 21 and the first liquid storage bin 13, and is used for allowing the aerosol matrix contained in the second liquid storage bin 21 to move to the first liquid storage bin 13; the air storage bin 14 is connected to the first liquid storage bin 13 and is close to the second liquid storage bin 21, and is used to contain a certain amount of air; the air guiding channel 1514 is connected to the air storage bin 14 and the second liquid storage bin 21.

[0053] Furthermore, by setting the air storage tank 14 to accommodate a certain amount of air, and setting the air guide channel 1514 connecting the air storage tank 14 and the second liquid storage tank 21, the atomizer 100 can provide air from the air storage tank 14 to the second liquid storage tank 21 in real time so that the air pressure between the second liquid storage tank 21 and the first liquid storage tank 13 is balanced, thereby making it difficult for the aerosol matrix contained in the second liquid storage tank 21 to continue to move to the first liquid storage tank 13 due to the effect of negative pressure.

[0054] The gas storage tank 14 is further connected to the first liquid storage tank 13, so that the first liquid storage tank 13, the gas storage tank 14, the air guide channel 1514 and the second liquid storage tank 21 are connected and in a state of air pressure balance, so that the aerosol matrix contained in the second liquid storage tank 21 can move smoothly to the first liquid storage tank 13 under its own gravity, thereby realizing real-time and efficient aerosol matrix replenishment of the first liquid storage tank 13.

[0055] For further information, see Figure 5-7 As shown, the main body 10 includes a liquid guide tube 1511 and an air guide tube 1513. The liquid guide tube 1511 is configured to form the liquid guide channel 1512, and the air guide tube 1513 is configured to form the air guide channel 1514.

[0056] In one embodiment, the liquid guiding tube 1511 and the air guiding tube 1513 are arranged at a certain distance, and the liquid guiding tube 1511 and the air guiding tube 1513 are respectively inserted into the second liquid storage tank 21.

[0057] In another embodiment, the main body 10 includes a puncture tube 151, which is separated by a partition plate 1519 to form the liquid catheter 1511 and the air catheter 1513, and the puncture tube 151 is inserted into the second liquid storage tank 21, so that the liquid catheter 1511 and the air catheter 1513 are inserted into the second liquid storage tank 21 together.

[0058] The puncture tube 151 is separated by the partition plate 1519 to form the liquid guide tube 1511 and the air guide tube 1513, so that the structure of the liquid guide tube 1511 and the air guide tube 1513 is more compact, and it is convenient to insert the liquid guide tube 1511 and the air guide tube 1513 into the second liquid storage tank 21 together. At the same time, the overall structural strength of the liquid guide tube 1511 and the air guide tube 1513 is increased, so as to extend the service life of the liquid guide tube 1511 and the air guide tube 1513.

[0059] Furthermore, the cross-section of the liquid conducting channel 1512 may be a regular or irregular shape such as a circle, an ellipse, a rectangle, a triangle, a heart shape, etc.; or, the liquid conducting channel 1512 may be composed of multiple connected sections, and the shapes of the cross-sections corresponding to the liquid conducting channel 1512 in different sections may be different, which is not limited here.

[0060] Furthermore, the liquid conducting path of the liquid conducting channel 1512 can be a regular or irregular path such as a straight line, an arc line, an S line, etc.; or, the liquid conducting path can also be divided into multiple sections, and the liquid conducting paths in different sections can be different, which is not limited here.

[0061] Furthermore, the cross-section of the air guiding channel 1514 may be a regular or irregular shape such as a circle, an ellipse, a rectangle, a triangle, a heart shape, etc.; or, the air guiding channel 1514 may be composed of multiple connected sections, and the shapes of the cross-sections corresponding to the air guiding channels 1514 in different sections may be different, which is not limited here.

[0062] Furthermore, the air guiding path of the air guiding channel 1514 can be a regular or irregular path such as a straight line, an arc line, an S line, etc.; or, the air guiding path can also be divided into multiple sections, and the air guiding paths in different sections can be different, which is not limited here.

[0063] For further information, see Figure 3-4 and Figure 8 As shown, the liquid storage unit 20 includes a first shell 22, a second shell 23 and a first sealing seat 24. The first shell 22 and the second shell 23 are sealed and connected via the first sealing seat 24 to form the second liquid storage tank 21.

[0064] Furthermore, the first shell 22 is structured to form a first plug-in portion 221, and the second shell 23 is structured to form a second plug-in portion 231. The second plug-in portion 231 is adapted to the first plug-in portion 221, and the first plug-in portion 221 and the second plug-in portion 231 are plugged into each other to form an installation space. The first sealing seat 24 is sealed in the installation space, and the connection between the first shell 22 and the second shell 23 is sealed, so that the first shell 22 and the second shell 23 are sealed and connected, and together with the first sealing seat 24, the second liquid storage tank 21 is formed, thereby preventing the aerosol matrix contained in the second liquid storage tank 21 from leaking from the connection between the first shell 22 and the second shell 23.

[0065] Furthermore, the first sealing seat 24 is constructed to form a sealing hole 241 and a sealing film 242, and the sealing film 242 is arranged in the sealing hole 241 to close the sealing hole 241, thereby ensuring that the aerosol matrix contained in the second liquid storage tank 21 will not leak from the sealing hole 241 when the liquid storage unit 20 is not connected to the main body 10 to be in an independent state.

[0066] For further information, please refer to Figure 7 As shown, the puncture tube 151 is formed with a puncture portion 1515 in a direction away from the first liquid storage tank 13. The puncture portion 1515 is used to be inserted into the sealing hole 241 and puncture the sealing film 242 when the liquid storage unit 20 is connected to the main body 10, so that the outer wall of the puncture tube 151 is sealed and connected with the inner wall of the sealing hole 241, and the air guide channel 1514 is connected to the air storage tank 14 and the second liquid storage tank 21, and the liquid guide channel 1512 is connected to the first liquid storage tank 13 and the second liquid storage tank 21.

[0067] Specifically, when the liquid storage unit 20 is connected to the main body 10 , the puncture portion 1515 is used to puncture the sealing film 242 , and the sealing hole 241 is sealed and connected to the outer walls of the liquid guide tube 1511 and the air guide tube 1513 .

[0068] Furthermore, the puncture portion 1515 includes a first sub-puncture portion 1516 and a second sub-puncture portion 1517, and the first sub-puncture portion 1516 and the second sub-puncture portion 1517 are spaced apart to form a notch 1518, and the bottom of the notch 1518 is flush with the opening end of the sealing hole 241 connected to the second liquid storage tank 21, so that all aerosol substrates contained in the second liquid storage tank 21 can smoothly enter the liquid guide channel 1512 through the notch 1518 and move to the first liquid storage tank 13.

[0069] For further information, see Figure 3-4 and Figure 8-9 As shown, the liquid storage unit 20 further includes a support member 25. The support member 25 is supported in the second liquid storage tank 21 and is used to at least limit the deformation of one of the first sealing seat 24, the first shell 22, and the second shell 23.

[0070] Further, the first plug-in portion 221 is plugged into the inner side of the second plug-in portion 231. The first shell 22 is structured to form a plurality of reinforcing ribs 222, which are respectively located in the second liquid storage tank 21 and respectively have limiting surfaces 223 facing the first sealing seat 24. The support member 25 is arranged in the installation space and abuts between the limiting surface 222 and the first sealing seat 24, so as to cooperate with the second shell 23 to limit the first sealing seat 24, so that the first sealing seat 24 can be effectively sealed and connected at the connection between the first plug-in portion 221 and the second plug-in portion 231, and the first sealing seat 24 is limited from entering the second liquid storage tank 21 due to extrusion deformation, resulting in a change in the volume of the second liquid storage tank 21, causing the aerosol matrix contained in the second liquid storage tank 21 to leak due to the volume change.

[0071] Furthermore, the side wall of the support member 25 is also supported on the inner wall of the first plug-in portion 221 located on the inner side, thereby preventing the first shell 22 from deforming near the first plug-in portion 221 and causing the volume of the second liquid storage tank 21 to change.

[0072] For further information, see Figure 3-4 and Figure 8 As shown, a liquid injection hole 243 is provided on the first sealing seat 24 , and the liquid injection hole 243 is connected to the second liquid storage tank 21 for filling the aerosol matrix into the second liquid storage tank 21 .

[0073] The liquid storage unit 20 further includes a liquid injection plug 26 , which is sealed and connected to the liquid injection hole 243 to block the liquid injection hole 243 .

[0074] Among them, one end of the injection plug 26 away from the second liquid storage tank 21 is limited in the injection hole 243 and abuts against the inner wall of the corresponding first shell 22 or the second shell 23, so that the injection plug 26 will not fall out of the injection hole 243, thereby maintaining the sealing effect of the injection hole 243.

[0075] For further information, see Figure 3-7 As shown, the main body 10 includes a third shell 15 and a fourth shell 16. The third shell 15 and the fourth shell 16 are connected to form a receiving space 17, and the liquid storage unit 20 is arranged in the receiving space 17, so that the liquid storage unit 20 is built into the main body 10, thereby avoiding the risk of the liquid storage unit 20 being easily separated from the main body 10 when it is partially placed outside the main body 10.

[0076] Furthermore, the third shell 15 is constructed to form the first liquid storage tank 13 , the atomization channel, the liquid guiding channel 1512 , the gas storage tank 14 and the gas guiding channel 1514 .

[0077] Specifically, the third housing 15 includes a first connection shell 152, a second connection shell 153 and a second sealing seat 154. The first connection shell 152 and the second connection shell 153 are sealed and connected via the second sealing seat 154 to define the first liquid storage tank 13 and the gas storage tank 14.

[0078] Furthermore, the first connecting shell 152 is structured to form a third plug-in portion 1521, and the second connecting shell 153 is structured to form a fourth plug-in portion 1531. The fourth plug-in portion 1531 is adapted to the third plug-in portion 1521, and the third plug-in portion 1521 and the fourth plug-in portion 1531 are plugged into each other to form a accommodating space. The second sealing seat 154 is arranged in the accommodating space, and the connection between the first connecting shell 152 and the second connecting shell 153 is sealed, so that the first connecting shell 152 and the second connecting shell 153 are sealed and connected, and together with the second sealing seat 154, the first liquid storage tank 13 and the gas storage tank 14 are formed, and the aerosol matrix contained in the first liquid storage tank 13 is prevented from leaking from the connection between the first connecting shell 152 and the second connecting shell 153.

[0079] Furthermore, the first connecting shell 152 extends outwardly from one side of the second connecting shell 153 to form the liquid guiding tube 1511 and the air guiding tube 1513 . The air guiding tube 1513 forms the air guiding channel 1514 , and the liquid guiding tube 1511 forms the liquid guiding channel 1512 .

[0080] For further information, see Figure 3-5 As shown, the main body 10 further includes a liquid storage member 18. The liquid storage member 18 is disposed in the first liquid storage bin 13 and is used to lock the aerosol matrix in the first liquid storage bin 13 to prevent the aerosol matrix in the first liquid storage bin 13 from directly leaking from the atomizer core 11.

[0081] Furthermore, by providing the liquid storage component 18, the aerosol matrix supplied by the second liquid storage tank 21 can also be effectively locked, thereby preventing the aerosol matrix in the first liquid storage tank 13 from directly leaking from the atomizer core 11 due to the lack of locking of the liquid storage component 18.

[0082] Furthermore, the gas storage bin 14 is defined between the liquid storage member 18 and the first connecting shell 152. The gas storage bin 14 is close to the second liquid storage bin 21, so that in the suction state, the gas storage bin 14 is not filled with aerosol matrix, so that the gas storage bin 14 and the air guide channel 1514 are connected to the first liquid storage bin 13 and the second liquid storage bin 21, so that the first liquid storage bin 13 and the second liquid storage bin 21 are in a state of air pressure balance.

[0083] Furthermore, the fourth housing 16 is structured to form a suction nozzle 161. The suction nozzle 161 is located at a side of the receiving space 17 away from the first liquid storage tank 13 and is connected to the atomization airway. When inhaling, the aerosol diffused into the atomization channel will flow out of the atomizer 100 from the suction nozzle 161.

[0084] For further information, see Figure 3-7 and Fig.10 As shown, the liquid storage unit 20 is structured to form an avoidance hole 27. The third shell 15 extends toward the suction nozzle 161 to form a connecting pipe portion 1522, which is penetrated through the avoidance hole 27 and is sealed and abutted with the suction nozzle 161 through a sealing member 19, so that the suction nozzle 161 is connected to the connecting pipe portion 1522.

[0085] The main body 10 further includes an atomizing tube 12. The atomizing tube 12 is disposed in the connecting tube portion 1522, and the atomizing core 11 is at least partially disposed in the atomizing tube 12, and is structured with the atomizing tube 12 to form the atomizing channel.

[0095] Furthermore, the first connection portion 271 may be a limiting groove, and the second connection portion 1523 may be a limiting protrusion. By setting the first connection portion 271 and the second connection portion 1523 to limit each other, the liquid storage unit 20 can be more stably accommodated in the accommodation space 17.

[0096] Furthermore, the first connecting shell 152 also has a fifth plug-in portion 1524, and the fourth shell 16 has a sixth plug-in portion 162, the sixth plug-in portion 162 is adapted to the fifth plug-in portion 1524, and the sixth plug-in portion 162 and the fifth plug-in portion 1524 are mutually plugged in to connect the third shell 15 and the fourth shell 16 to each other.
