[0034] The present application aims to improve the oil supply efficiency of an external liquid storage tank to an aerosol generating device, and provides a secondary oil tank and an aerosol generating system. The secondary oil tank includes a housing assembly and a connecting member. The housing assembly has a liquid storage cavity for storing a liquid aerosol generating matrix, and the connecting member connects the liquid storage cavity to the aerosol generating device to ensure the liquid supply function of the secondary oil tank to the aerosol generating device. The secondary oil tank further includes a movable member, which is accommodated in the liquid storage cavity and can move in the liquid storage cavity. When the liquid aerosol generating matrix in the liquid storage cavity flows to the aerosol generating device through the connecting member, the volume of the liquid aerosol generating matrix in the liquid storage cavity decreases, and the movable member is configured to: when moving in the liquid storage cavity, squeeze the aerosol generating matrix in the liquid storage cavity to flow to the aerosol generating device, effectively avoiding the formation of negative pressure in the liquid storage cavity and effectively improving the liquid supply efficiency of the secondary oil tank to the aerosol generating device. For specific details, please refer to the following embodiments.

[0035] Please refer to Figure 1 , in an embodiment of the present application, an aerosol generating system 100 is provided, which includes an aerosol generating device 10 for heating and atomizing to generate aerosol and a secondary oil tank 20 for providing an aerosol generating matrix to the aerosol generating device 10. The secondary oil tank 20 is installed outside the aerosol generating device 10 for easy disassembly and replacement.

[0036] Please refer to in combination withFigure 1 , Figure 2 and Figure 3 , wherein the auxiliary oil tank 20 includes a housing assembly 21, a connecting member 22 and a movable member 23. The housing assembly 21 is mounted on the aerosol generating device 10 and has a liquid storage cavity 211 for storing the aerosol generating matrix therein. The connecting member 22 is located on the housing assembly 21, and the connecting member 22 connects the liquid storage cavity 211 with the aerosol generating device 10, so that the aerosol generating matrix in the liquid storage cavity 211 can flow to the aerosol generating device 10 through the connecting member 22, replenishing the aerosol generating matrix for the aerosol generating device 10, which helps to extend the service life of the aerosol generating device 10 and the aerosol generating system 100; The movable member 23 is received in the liquid storage cavity 211 and can move in the liquid storage cavity 211. The outer periphery of the movable member 23 fits against the inner wall of the liquid storage cavity 211. The bottom surface of the movable member 23 and the inner wall of the liquid storage cavity 211 enclose a variable oil tank 2111 for storing the liquid aerosol generating matrix. When the movable member 23 moves in the liquid storage cavity 211, the volume of this variable oil tank 2111 decreases, squeezing the aerosol generating matrix in the liquid storage cavity 211 to flow out through the connecting member 22 and towards the aerosol generating device 10. At the same time, since the variable oil tank 2111 decreases as the aerosol generating matrix flows out, it is possible to avoid the formation of negative pressure in the storage space, and the negative pressure will hinder the outflow of the aerosol generating matrix. This enables the auxiliary oil tank 20 to promote the flow of the aerosol generating matrix from the liquid storage cavity 211 to the aerosol generating device 10 and improve the liquid supply efficiency.

[0037] Please continue to refer to Figure 1 and Figure 2 , further, a plurality of sealing ribs 231 are provided around the outer periphery of the movable member 23, and the plurality of sealing ribs 231 are arranged at intervals; By using the sealing ribs 231, the sealing performance between the movable member 23 and the inner wall of the liquid storage cavity 211 can be enhanced, so that the variable oil tank 2111 for storing the aerosol generating matrix formed by the movable member 23 and the liquid storage cavity 211 will not leak during the movement of the movable member 23.

[0038] Please continue to refer to Figure 1 , Figure 2 and Figure 3, in one embodiment, the auxiliary oil storage chamber 20 further includes an actuating member 24. The actuating member 24 is mounted on the housing assembly 21 and can slide relative to the housing assembly 21. The actuating member 24 is connected to the movable member 23, so that when the actuating member 24 slides relative to the housing assembly 21, it drives the movable member 23 to move in the liquid storage cavity 211 to change the storage space size of the aerosol-forming substrate. The actuating member 24 and the movable member 23 can be fixedly connected, such as integrally formed by injection molding or welding; they can also be detachably connected for easy disassembly and installation. When using a detachable connection method, the bottom end of the actuating member 24 is detachably connected to the movable member 23. The detachable connection method can be a threaded connection, magnetic attraction, etc. For example, the bottom end of the actuating member 24 is provided with a thread, and a threaded hole is formed on the movable member 23 to cooperate with it; or, one of a magnetic attracting member and a magnetic part is provided on the movable member 23, and the other of the magnetic attracting member and the magnetic part is provided on the actuating member 24; due to the mutual attraction between the magnetic part and the magnetic attracting member, the connection between the actuating member 24 and the movable member 23 is fixed.

[0039] Please refer to in combination Figure 2 , Figure 3 and Figure 4 , further, the housing assembly 21 includes a first end face 212 and a second end face 213 arranged opposite to each other. Through holes 214 are provided on at least one of the first end face 212 and the second end face 213, so that one end of the actuating member 24 can pass through the through hole 214 from outside the liquid storage cavity 211 and be fixedly connected to the movable member 23, so that the actuating member 24 can drive the movable member 23 to move in the liquid storage cavity 211; if the first end face 212 is closer to the connecting member 22 than the second end face 213 and the through hole 214 is located on the first end face 212, the actuating member 24 can be pulled outwards to reduce the storage space of the aerosol-forming substrate in the liquid storage cavity 211, prompting the aerosol-forming substrate to flow out quickly; if the first end face 212 is closer to the connecting member 22 than the second end face 213 and the through hole 214 is located on the second end face 213, the actuating member 24 can be pushed inwards to reduce the storage space of the aerosol-forming substrate in the liquid storage cavity 211, prompting the aerosol-forming substrate to flow out quickly.

[0040] Please continue to refer to in combination Figure 3 and Figure 4 , further, the housing assembly 21 has a sliding groove 215 arranged along a preset direction. The actuating member 24 is clamped and received in the sliding groove 215 and can slide in the sliding groove 215. By limiting and guiding the sliding process of the actuating member 24 through the sliding groove 215, the smoothness of the movement of the actuating member 24 can be improved, and then the movable member 23 can be driven to slide smoothly in the liquid storage cavity 211.

[0041] Please refer to Figure 5, in yet another embodiment, the housing assembly 21 is disassembled into an upper cover 216 and a bottom cylinder 217. The upper cover 216 is detachably connected to the bottom cylinder 217 and closes the top opening of the bottom cylinder 217. The actuating member 24 passes through the top surface of the upper cover 216. The disassembled design of the housing assembly 21 facilitates the assembly of the actuating member 24 and the movable member 23.

The housing assembly has a liquid storage cavity for storing a liquid aerosol generating substrate. The connecting member connects the liquid storage cavity to the aerosol generating device to ensure the liquid supply function of the secondary oil sump to the aerosol generating device. The secondary oil sump further includes a movable member that is accommodated in the liquid storage cavity and can move in the liquid storage cavity. When the liquid aerosol generating substrate in the liquid storage cavity flows to the aerosol generating device via the connecting member, the volume of the liquid aerosol generating substrate in the liquid storage cavity decreases. The movable member is configured to: when moving in the liquid storage cavity, squeeze the aerosol generating substrate in the liquid storage cavity to flow to the aerosol generating device, effectively preventing the formation of negative pressure in the liquid storage cavity and effectively improving the liquid supply efficiency of the secondary oil sump to the aerosol generating device.
