[0064] The present application provides an aerosol generating device 10, such as Figure 1-2 , Fig.13 and Fig.24 As shown, it includes a liquid reservoir 1 and a device body 2. The liquid reservoir 1 includes a first shell 11 and a first bracket 12, the first bracket 12 is connected to the first shell 11, and a first liquid reservoir 13 for storing a liquid matrix is ​​defined between the first shell 11 and the first bracket 12. The device body 2 includes the second shell 21, and a second liquid reservoir 23 for storing a liquid matrix is ​​defined inside the second shell 21. The device body includes an atomization assembly 3, which is arranged inside the device body 2 and is used to heat the liquid matrix from the second liquid reservoir 23 to generate an aerosol. The first bracket 11 has an annular insertion portion 121, the insertion portion 121 extends in a direction away from the first liquid reservoir 13, and at least one first liquid guide hole 122 is arranged on the insertion portion 121. The device body 2 defines a receiving chamber 24 for receiving at least part of the insertion portion 121. When at least part of the insertion portion 121 is received in the receiving chamber 24, the first liquid guide hole 121 provides a liquid flow path for the liquid matrix in the first liquid reservoir 13 to flow to the second liquid reservoir 23.

[0065] The aerosol generating device 10 provided in the present application is as follows: Figure 3-4 , Figure 14-15 As shown, the first bracket 12 has an annular insertion portion 121 and a first liquid guide hole 122, the device body 2 is defined by a receiving cavity 24, and the insertion portion 121 is inserted into the receiving cavity 24 in a direction away from the first liquid storage cavity 13. When the liquid reservoir 1 is installed to the device body 2, there is no need to consider the installation direction, and the liquid reservoir 1 can be installed to the device body 2, so that the liquid in the first liquid storage cavity 13 and the second liquid storage cavity 23 are connected, and the liquid reservoir 1 supplies oil to the device body 2.

[0066] In one embodiment of the present application, the aerosol generating device 10 includes a liquid storage member 25, which is located in the second liquid storage chamber 23 and is used to receive and retain the liquid matrix from the first liquid storage chamber 13. The liquid storage member 25 allows the liquid matrix in the second liquid storage chamber 23 to be adsorbed and retained on the liquid storage member 25, and is not easy to leak when the device body 2 is stationary or transported; and when inhaling, the liquid matrix in the liquid storage member 25 can enter the atomization component 3 in time to avoid dry burning and maintain a good taste. In addition, after the liquid reservoir 1 is installed with the device body 2, the liquid matrix in the first liquid storage chamber 13 can supplement the liquid matrix in the second liquid storage chamber 23, so that the aerosol generating device 10 maintains a larger capacity. In addition, the liquid storage member 25 allows the liquid matrix in the second liquid storage chamber 23 to be absorbed and retained without leakage.

[0067] In one embodiment of the present application, the inserting portion 121 defines an annular liquid guiding groove 123, the liquid guiding groove 123 and the first liquid guiding hole 121 are in liquid conduction, and the aperture of the first liquid guiding hole 122 is smaller than the radial width of the liquid guiding groove 123. The aperture of the first liquid guiding hole 122 is smaller than the aperture of the hollow portion of the liquid guiding groove 123, so that the liquid matrix flows out of the first liquid guiding hole 122 at a slower speed, thereby preventing the liquid matrix from leaking from the atomizing assembly 3 after the liquid storage member 25 of the second liquid storage chamber 23 retains too much liquid matrix. In one embodiment of the present application, the aperture of the first liquid guiding hole 122 is 0.2 mm-1.2 mm. When the aperture of the first liquid guide hole 122 is 0.2 mm-1.2 mm, the first liquid guide hole 122 has a capillary effect, and only when the liquid matrix in the second liquid storage chamber 23 is consumed by the atomizer assembly 3 and the air pressure in the second liquid storage chamber 23 is reduced, the liquid matrix in the liquid guide groove 123 will flow out from the first liquid guide hole 122; and when the atomizer assembly 3 is not working and the liquid matrix in the second liquid storage chamber 23 is not consumed, the first liquid guide hole 122 has a certain retention effect on the liquid matrix, and the liquid matrix in the liquid guide groove 121 will not flow out from the first liquid guide hole 122. In one embodiment of the application, the first liquid guide hole 122 can be circular, triangular, polygonal, etc.

[0068] In one embodiment of the present application, the first bracket 12 is defined with a first liquid guide groove 1231 and a second liquid guide groove 1232, the radial width of the first liquid guide groove 1231 is greater than the radial width of the second liquid guide groove 1232, and the first liquid guide groove 1231 is closer to the first liquid storage cavity than the second liquid guide groove 1232. The radial widths of the first liquid guide groove 1231 and the second liquid guide groove 1232 are distributed in a stepped manner, which can control the supply amount of the liquid matrix and is also conducive to keeping the first sealing member 41 on the first bracket 12. In one embodiment of the present application, the first liquid guide hole 122 is located in the second liquid guide groove 1232, so as to drain the liquid matrix to the outside of the insertion portion 121.

[0069] In one embodiment of the present application, the first liquid guide hole 122 is disposed on the side wall of the inserting portion 121. After the liquid matrix in the first liquid storage chamber 13 enters the liquid guide groove 123, it flows out from the first liquid guide hole 122 on the side wall of the inserting portion 121. In one embodiment of the present application, the first liquid guide hole 122 is disposed on the bottom wall of the inserting portion 121. After the liquid matrix in the first liquid storage chamber 13 enters the liquid guide groove 123, it flows out from the first liquid guide hole 122 on the bottom wall of the inserting portion 121. Under the action of gravity, the liquid matrix has a faster flow rate. In one embodiment of the present application, there are multiple first liquid guide holes 122, preferably, there are 4 first liquid guide holes, so that when each first liquid guide hole 122 has a smaller flow rate, the multiple first liquid guide holes 122 can still allow the liquid matrix in the first liquid storage chamber 13 to flow out to ensure a certain flow rate, ensuring that the liquid matrix can be supplied from the first liquid storage chamber 13 to the second liquid storage chamber 23, and then absorbed and retained by the liquid storage member 25 in the second liquid storage chamber 23, which can ensure that the atomizer component 3 is not dry-burned and does not leak from the atomizer component 3.

[0070] In one embodiment of the present application, Figure 1-2 As shown, the first shell 11 includes a hollow first air pipe 14, and the first air pipe 14 is connected to the first bracket 12. In one embodiment of the present application, the first air pipe 14 is embedded in the first bracket 12, and the first bracket 12 has a first bracket mounting hole 124 for mounting the first air pipe 14. The first bracket 12 is also provided with a first protrusion 125 on one side close to the first air pipe 14. The first protrusion 125 is provided on the side of the first bracket 12 facing the first liquid storage chamber 13, and the first protrusion 125 facilitates the positioning of the first air pipe 14 during the installation of the first bracket 12. In one embodiment of the present application, the insertion portion 121 is a portion of the first bracket 12 extending toward the device body 2, and the insertion portion 121 is annular, so that when the liquid storage chamber 1 is installed to the device body 2, there is no need to consider the installation direction.

[0071] In one embodiment of the present application, Fig.13 and Fig.21 As shown, the first housing 11 includes a hollow first air pipe 14, and the first bracket 12 includes a hollow second air pipe 126, and the second air pipe 126 is connected to the first air pipe 14. In one embodiment of the present application, at least part of the second air pipe 126 constitutes the insertion portion 121, and at least part of the outer side wall of the second air pipe 126 is the inner side wall of the liquid guide groove 123.

[0072] In one embodiment of the present application, the device body 2 has a second bracket 22, such as Figure 5-7As shown, the second bracket 22 is connected to the second shell 21, and the second bracket 22 defines a receiving cavity 24, and the insertion portion 121 is inserted into the receiving cavity 24. In one embodiment of the present application, the second bracket 22 has a second liquid guide hole 221, and the first liquid storage cavity 13, the first liquid guide hole 122, the second liquid guide hole 221 and the second liquid storage cavity 23 are liquid-conductive. In one embodiment of the present application, a liquid flow cavity 222 is defined between the first bracket 12 and the second bracket 22, and the liquid matrix in the first liquid storage cavity 13 flows through the first liquid guide hole 122 and enters the liquid flow cavity 222. In one embodiment of the present application, the aperture of the second liquid guide hole 221 is 0.2mm-1.2mm. When the aperture of the second liquid guide hole 221 is 0.2mm-1.2mm, the second liquid guide hole 221 has a capillary effect, and only when the liquid matrix in the second liquid storage chamber 23 is consumed by the atomizer assembly 3 and the air pressure in the second liquid storage chamber 23 is reduced, the liquid matrix in the liquid flow chamber 222 will flow out from the second liquid guide hole 221; and when the atomizer assembly 3 is not working and the liquid matrix in the second liquid storage chamber 23 is not consumed, the second liquid guide hole 211 has a certain retention effect on the liquid matrix, and the liquid matrix in the liquid flow chamber 222 will not flow out from the second liquid guide hole 221. In one embodiment of the application, the second liquid guide hole 221 can also be circular, triangular, polygonal and other shapes. In one embodiment of the application, the second liquid guide hole 221 may not have a capillary effect, as long as it has the performance of passing the liquid matrix.

[0073] In one embodiment of the present application, Figure 5 As shown, the inner diameter of the second liquid guide hole 221 gradually decreases in the direction toward the second liquid storage cavity 23 , which can reduce the rate of supplying the liquid matrix into the second liquid storage cavity 23 on the one hand, and facilitate the manufacture and processing of the second bracket 22 on the other hand.

[0074] In one embodiment of the present application, the number of the second liquid guide holes 221 is multiple, preferably, the number of the second liquid guide holes 221 is 4, so that when each second liquid guide hole 221 has a relatively low flow rate, the multiple second liquid guide holes 221 can still allow the liquid matrix in the liquid flow chamber 222 to flow out to ensure a certain flow rate, ensuring that the liquid matrix can be supplied from the liquid flow chamber 222 to the second liquid storage chamber 23, and then absorbed and retained by the liquid storage member 25 in the second liquid storage chamber 23, which can ensure that the atomization assembly 3 is not dry-burned and does not leak from the atomization assembly 3. In one embodiment of the present application, the multiple second liquid guide holes 221 are evenly distributed along the circumferential direction of the second bracket 22, so that the liquid matrix in the receiving chamber 24 flows evenly to the liquid storage member 25 in the second liquid storage chamber 23 along the circumferential direction of the second bracket 22, so that the liquid matrix in the liquid storage member 25 is evenly distributed.

[0075] In one embodiment of the present application, a first gap 223 is defined between the insertion portion 121 and the wall defining the receiving cavity 24, and the first gap 223 and the first liquid guide hole 122 are in liquid conduction. In one embodiment of the present application, the width of the first gap 223 is 0.2mm-1.2mm, so that the first gap 223 has a capillary effect, and the liquid matrix in the first gap 223 will flow out only when the liquid matrix in the second liquid storage cavity 23 is consumed by the atomization component 3 and the air pressure in the second liquid storage cavity 23 is reduced; and when the atomization component 3 is not working and the liquid matrix in the second liquid storage cavity 23 is not consumed, the first gap 223 has a certain retention effect on the liquid matrix, and the liquid matrix will not flow out from the first gap 223.

[0076] In one embodiment of the present application, the first gap 223 is located between the insertion portion 121 of the first bracket 12 and the second bracket 22, and the first gap 223 is defined between the outer wall of the insertion portion 121 and the inner wall of the receiving cavity 24. In one embodiment of the present application, the first liquid guide hole 122 is provided on the side wall of the insertion portion 121, and the first gap 223 is located between the outer side wall of the insertion portion 121 and the inner side wall of the receiving cavity 24. In one embodiment of the present application, the first liquid guide hole 122 is provided on the bottom wall of the insertion portion 121, and the first gap 223 is located between the outer bottom wall of the insertion portion 121 and the inner bottom wall of the receiving cavity 24.

[0077] In one embodiment of the present application, the device body 2 also includes a first seal 41 disposed adjacent to the receiving chamber 24 or used to define the receiving chamber 24, and at least a portion of the first seal 41 surrounds the insertion portion 121. In one embodiment of the present application, the first seal 41 is located between the first bracket 12 and the second bracket 22, and the first seal 41 can prevent leakage of the liquid matrix in the liquid flow chamber 222 between the first bracket 12 and the second bracket 22, and make the understanding between the first bracket 12 and the second bracket 22 more secure. In one embodiment of the present application, the device body 2 includes a support tube 31 for holding the atomization assembly 3, and the support tube 31 is installed in the mounting hole 224 of the second bracket 22. In one embodiment of the present application, as Figure 8-10As shown, the first seal 41 has a first liquid channel 411 and a first gas channel 412. The first liquid channel 411 is located in the liquid flow chamber 222, so that the liquid matrix in the liquid flow chamber 222 can pass through the first seal 41 from the first liquid channel 411; the first gas channel 412 is located between the first air pipe 14 and the atomization assembly 3, so that the first air pipe and the atomization assembly 3 are gas-conductive. In one embodiment of the present application, the number of the first liquid channels 411 is multiple, for example, the number of the first liquid channels 411 may be 4, 6, 8, 10, etc. In one embodiment of the present application, the multiple first liquid channels 411 are evenly distributed along the circumferential direction of the first seal 41. In one embodiment of the present application, the number of the second liquid guide holes 221 is 4, and the number of the first liquid channels 411 is 8.

When the atomizer assembly 3 is working, the atomizer assembly 3 consumes the liquid matrix in the liquid storage part 25. At this time, the air pressure in the second liquid storage chamber 23 is reduced, and air can enter the liquid storage chamber through the first air channel 225, and then enter the gas chamber 227, so that the air pressure in the gas chamber 227 is balanced with the atmospheric pressure, ensuring that the liquid matrix in the liquid storage part 25 can be normally supplied to the atomizer assembly 3. On the other hand, after the air pressure in the gas chamber 227 is reduced, the liquid matrix in the first liquid storage chamber 13 flows through the first liquid guide hole 122, the liquid flow chamber 222, and the second liquid guide hole 221, and enters the second liquid storage chamber 23. However, when the atomizer assembly is not working, since at least one of the first liquid guide hole 122, the first gap 223 and the second liquid guide hole 221 has a capillary effect, the liquid matrix is ​​retained in at least one of the first liquid guide hole 122, the first gap 223 and the second liquid guide hole 221 having a capillary effect, thereby achieving the effect of the aerosol generating device 10 supplying oil on demand and avoiding leakage of the liquid matrix from the atomizer assembly 3.
