For ordinary technicians in this field, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0039] Based on the technical problem that the product volume of the aerosol atomization equipment is limited and the capacity of the aerosol generating matrix is ​​limited, the present application provides an external liquid storage device and an atomization system. The external liquid storage device and the atomization system are used to store liquid aerosol generating matrix for supplying liquid to the atomization equipment, so that the atomization equipment can additionally store the aerosol generating matrix and increase the capacity of the aerosol generating matrix. For details, please refer to the following embodiments.

[0040] Please refer to Figure 1 and Figure 2 One embodiment of the present application provides an atomization system 100, including an atomization device 20 and an external liquid storage device 10; the external liquid storage device 10 stores liquid aerosol generating substrate, and is used to supply liquid to the atomization device 20, so that the atomization device 20 can additionally store the aerosol generating substrate, thereby increasing the capacity of the aerosol generating substrate. The atomization device 20 has a nozzle 21 and an atomization core 22, the nozzle 21 is connected to the atomization core 22, the atomization core 22 heats the atomized aerosol generating substrate to generate aerosol, and the user inhales the nozzle 21, so that the aerosol flows out of the nozzle 21 for the user to use.

[0041] Please refer to Figure 1 , Figure 2 and Figure 3The external liquid storage device 10 is installed on the atomizing device 20, and a detachable installation method is adopted, such as a plug-in method. Specifically, the shell 24 of the atomizing device 20 is provided with a hollow liquid inlet hole 241, and the bottom end of the external liquid storage device 10 is provided with a protruding insertion end 11, and the insertion end 11 is plugged into the liquid inlet hole 241, so that the liquid aerosol generating matrix in the external liquid storage device 10 can flow into the liquid inlet hole 241 through the insertion end 11, so as to supply liquid to the atomizing device 20; blocks are provided on both sides of the insertion end 11, and after the insertion end 11 is inserted into the liquid inlet hole 241, the insertion end 11 is fixed to the atomizing device 20 through the blocks, so that the external liquid storage device 10 is stably installed on the atomizing device 20; a silicone plug can be provided between the liquid inlet hole 241 and the insertion end 11 to enhance the sealing performance of the liquid inlet hole 241 and the insertion end 11, so as to prevent the aerosol generating matrix from leaking in the process of flowing to the liquid inlet hole 241 through the insertion end 11.

[0042] Please continue to refer to Figure 1 , Figure 2 and Figure 3The atomizing device 20 has a main liquid tank 23 for storing liquid aerosol generating substrate, and the atomizing core 22 is installed on the main liquid tank 23; the main liquid tank 23 is provided with a liquid feeding hole 231, through which the atomizing core 22 is supplied with liquid. When the user sucks on the suction nozzle 21, negative pressure is formed, which prompts the aerosol generating substrate in the main liquid tank 23 to flow out of the liquid feeding hole 231, thereby supplying liquid to the atomizing core 22. Since the liquid feeding hole 231 is located between the atomizing core 22 and the suction nozzle 21, when the user sucks on the suction nozzle 21, the height of the liquid feeding hole 231 is above the atomizing core 22, so that the aerosol generating substrate flowing out of the liquid feeding hole 231 flows downward to the atomizing core 22, and is directly heated and consumed by the atomizing core 22 for atomization, which is beneficial to preventing pollution caused by leakage of the aerosol generating substrate. The external liquid storage device 10 is provided with a liquid supply hole 132 for the liquid aerosol-generating matrix stored in the external liquid storage device 10 to flow out, and the external liquid storage device 10 supplies liquid to the atomizing device 20 through the liquid supply hole 132; the main liquid tank 23 is connected to the liquid supply hole 132. A temporary storage tank 25 can be provided on the atomizing device 20, and the temporary storage tank 25 is respectively connected to the liquid supply hole 132 and the main liquid tank 23, so that the aerosol-generating matrix flowing out of the liquid supply hole 132 first flows to the temporary storage tank 25, and finally flows to the main liquid tank 23, so as to supply liquid to the main liquid tank 23. A liquid guide tube 26 is provided between the main liquid tank 23 and the temporary storage tank 25, and the two ends of the liquid guide tube 26 are respectively connected to the main liquid tank 23 and the temporary storage tank 25, so as to ensure that the aerosol-generating matrix in the temporary storage tank 25 flows to the main liquid tank 23. The liquid guide tube 26 can be cut and formed by stainless steel SUS301 material or made of food-grade PC (polycarbonate) material by injection molding. The one-way valve 1412 can be made of environmentally friendly silicone material by injection molding. A silicone seat 27 with holes is provided at the bottom end of the main liquid tank 23, and one end of the liquid guide tube 26 is inserted into the hole of the silicone seat 27. A silicone seat 27 with holes is also provided near the temporary storage tank 25, and the other end of the liquid guide tube 26 is inserted into the hole of the silicone seat 27, which ensures the connection and sealing between the liquid guide tube 26 and the main liquid tank 23 and the temporary storage tank 25. The external liquid storage device 10, the temporary storage tank 25, the liquid guide tube 26, and the main liquid tank 23 jointly store and transport the liquid aerosol generation matrix for the atomization core 22 to heat and atomize, which effectively increases the capacity of the atomization system 100 for the aerosol generation matrix and extends the service life of the atomization system 100. The atomization device 20 is also provided with a battery assembly 28, and the atomization core 22 is powered by the battery assembly 28.

[0043] Please continue to refer to Figure 1 , Figure 2 and Figure 3, wherein the external liquid storage device 10 includes a liquid storage part 12, a liquid supply part 13 and a switch assembly 14; the liquid storage part 12 is provided with a liquid storage cavity 121 for storing an aerosol generating matrix and a liquid outlet 122 connected to the liquid storage cavity 121, so that the aerosol generating matrix in the liquid storage cavity 121 can flow out from the liquid outlet 122; the liquid supply part 13 is installed on the liquid storage part 12; the liquid supply part 13 is provided with a liquid supply cavity 131 connected to the liquid outlet 122, and the aerosol generating matrix flowing out of the liquid outlet 122 flows to the liquid supply cavity 131; The liquid supply part 13 is provided with a liquid supply hole 132 for communicating with the liquid supply cavity 131, and the liquid supply hole 132 is used to supply liquid to the atomizing device 20 to ensure the liquid supply function of the atomizing device 20; the switch component 14 is installed on the liquid storage part 12; the switch component 14 is used to open or close the liquid outlet hole 122 to control the aerosol generating matrix in the liquid storage cavity 121 to flow to the liquid supply cavity 131, thereby realizing the control of the liquid inlet amount of the atomizing device 20 by the external liquid storage device 10, and preventing the aerosol generating matrix in the atomizing device 20 from being excessively stored. When the pressure is high, it is large, causing leakage. At the same time, as the number of puffs by the user increases, the amount of liquid stored decreases, which reduces the liquid conduction rate of the atomizer core 22 and affects the taste. By adjusting the amount of liquid stored in the atomizer device 20, it is helpful to maintain the stability of the amount of liquid stored in the atomizer device 20, thereby maintaining a stable taste and avoiding dry burning. Specifically, when the aerosol generating matrix in the liquid supply part 13 is not consumed, the liquid outlet 122 is closed by the switch component 14, and the liquid storage chamber 121 and the liquid supply chamber 131 are two independently closed Space, only the aerosol generating matrix in the liquid supply chamber 131 will flow to the atomizing device 20, while the aerosol generating matrix in the liquid storage part 12 will not be affected; when the aerosol generating matrix in the liquid supply chamber 13 is about to be consumed or has been consumed, the liquid outlet 122 is opened by the switch component 14, at this time, the liquid storage chamber 121 and the liquid supply chamber 131 are connected through the liquid outlet 122, and the aerosol generating matrix in the liquid storage chamber 121 flows into the liquid supply chamber 131, and the switch component 14 is closed after the aerosol generating matrix fills the liquid supply chamber 131. The liquid storage part 12 and the liquid supply part 13 can adopt a split design, which can be detachably installed, or an integrated structure, which is integrally manufactured and molded. The capacity of the liquid storage chamber 121 can be the same as the capacity of the liquid supply chamber 131. Both the liquid storage part 12 and the liquid supply part 13 can be made of food-grade PC (polycarbonate) material and are injection molded.

[0044] Please continue to refer to Figure 1 , Figure 2 and Figure 3Furthermore, the liquid storage part 12 and the liquid supply part 13 are fixed by plugging, which is convenient for installation and disassembly. One of the liquid storage part 12 and the liquid supply part 13 is provided with a plug-in end 15, and the other is provided with a plug-in hole 16; the plug-in end 15 is plugged and fixed in the plug-in hole 16; the plug-in end 15 can be provided on the liquid storage part 12, the plug-in end 15 is located at the bottom end of the liquid storage part 12, the liquid outlet 122 is located at the plug-in end 15, and the plug-in hole 16 is located at the liquid supply part 13; the plug-in end 15 can also be provided on the liquid supply part 13, and the plug-in end 15 is located at the top end of the liquid supply part 13. A groove can be provided on the insertion end 11, and a sealing ring is placed in the groove to achieve a sealed connection between the liquid storage part 12 and the liquid supply part 13.

[0045] Please continue to refer to Figure 1 , Figure 2 and Figure 3 Furthermore, the plug-in end 15 is provided with a buckle 151, and the buckle 151 is clamped and fixed with the plug-in hole 16 to achieve reliability of fixing the liquid storage component 12 and the liquid supply component 13.

[0046] Please continue to refer to Figure 1 , Figure 2 and Figure 3 In one embodiment, the switch assembly 14 includes a transmission member 141 and a blocking member 142. One end of the transmission member 141 is inserted into the liquid outlet 122 along a preset direction, and the preset direction may be the axial direction of the transmission member 141; the blocking member 142 is connected to one end of the transmission member 141 through which the liquid outlet 122 is inserted, and the blocking member 142 moves between the first position and the second position under the drive of the transmission member 141, and the movement mode may be linear displacement or rotation around the axis, and the corresponding movement of the transmission member 141 is axial linear displacement and rotation around the axis. When the blocking member 142 is in the first position, the blocking member 142 blocks the liquid outlet 122, so that the aerosol-generating matrix in the liquid storage chamber 121 cannot flow to the liquid supply chamber 131 through the liquid outlet 122; when the blocking member 142 is in the second position, the liquid outlet 122 at least partially connects the liquid storage chamber 121 and the liquid supply chamber 131, and the aerosol-generating matrix in the liquid storage chamber 121 flows to the liquid supply chamber 131 through the liquid outlet 122, thereby realizing the opening and closing regulation of the liquid aerosol-generating matrix in the liquid storage chamber 121 flowing to the liquid supply chamber 131. If the blocking member 142 is linearly displaced in a preset direction, the first position and the second position are spaced apart in the preset direction; the transmission member 141 moves in a preset direction to drive the blocking member 142 to linearly displace and switch between the first position and the second position. If the blocking member 142 rotates around a preset direction, the first position and the second position are spaced apart along a plane perpendicular to the preset direction; the transmission member 141 rotates around the center line of the transmission member 141 to drive the blocking member 142 to rotate and switch between the first position and the second position.

[0047] Please refer to Figure 1 , Figure 2, Figure 3 , Figure 4 and Figure 5 Further, the transmission member 141 includes a vent pipe 1411 and a one-way valve 1412. One end of the vent pipe 1411 is disposed outside the liquid storage member 12 and communicates with the outside, and the other end is connected to the one-way valve 1412. The one-way valve 1412 is used to allow the vent pipe 1411 to be connected to the liquid supply member 13 in one direction. Figure 4 The middle arrow indicates the direction of external air flow, so that the external air can flow to the liquid supply part 13 through the vent pipe 1411 and the one-way valve 1412, supplying air to the liquid supply part 13, preventing the aerosol-generating matrix in the liquid supply part 13 from flowing out and causing negative pressure, which is conducive to the smooth outflow of the aerosol-generating matrix; because the one-way valve 1412 is one-way connected, the external air can flow into the liquid supply part 13 from the one-way valve 1412, while the aerosol-generating matrix in the liquid supply part 13 cannot flow out through the one-way valve 1412, which is conducive to preventing leakage. The top and bottom of the liquid storage part 12 are both provided with holes for the vent pipe 1411 to pass through, and a silicone plug is installed between the vent pipe 1411 and the hole for sealing to prevent leakage. The vent pipe 1411 can be cut and formed with stainless steel SUS301 material or made of food-grade PC (polycarbonate) material by injection molding. The one-way valve 1412 can be made of environmentally friendly silicone material by injection molding. A cap can be set at the end of the ventilation tube 1411 away from the one-way valve 1412 to isolate the outside world from the ventilation tube 1411, thereby preventing the outside air from directly contacting the aerosol generating matrix when not in use to cause oxidation; the cap can be removed when the ventilation tube 1411 is in use, which is very convenient.

[0048] Please continue to refer to Figure 4 and Figure 5 Furthermore, a one-way valve 1412 is provided through the liquid outlet 122, and the outer periphery and inner hole of the one-way valve 1412 are both conical, so that the one-way valve 1412 will be in a closed state when subjected to liquid pressure from the liquid supply part 13. However, when the atomizing device 20 is sucked, the aerosol generating matrix in the liquid supply part 13 flows out, and the negative pressure caused will cause the one-way valve 1412 to open, and external air will enter the liquid supply part 13, thereby realizing automatic liquid supply and avoiding leakage of the aerosol generating matrix from the one-way valve 1412.

[0049] Please continue to refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5In another embodiment, one end of the transmission member 141 is movable through the liquid storage chamber 121 and is located outside, and the other end is provided with a blocking member 142. The outer periphery of the blocking member 142 is in contact with the inner wall of the liquid outlet hole 122 and is plugged and sealed in the liquid outlet hole 122. The user can drive the blocking member 142 to move relative to the liquid outlet hole 122 by holding the end of the transmission member 141 that passes through the outside of the liquid storage member 12, so as to open or close the liquid outlet hole 122. The operation method is simple. For example, holding the transmission member 141 The blocking member 142 is displaced along the axial direction and is pulled out from the liquid outlet hole 122, so that the liquid aerosol generating matrix in the liquid storage chamber 121 can flow to the liquid supply chamber 131 through the liquid outlet hole 122, and the blocking member 142 is inserted into the liquid outlet hole 122, so that the blocking member 142 seals the liquid outlet hole 122 and blocks the liquid aerosol generating matrix in the liquid storage chamber 121 from flowing to the liquid supply chamber 131; other adjustment methods may also be used, such as rotating the transmission member 141, so that the blocking member 142 rotates to switch the position to realize opening or closing.

[0050] Please refer to Figure 1 , Figure 2 , Figure 3 , Figure 6 and Figure 7 Furthermore, the plugging member 142 is plugged and sealed in the liquid outlet hole 122, and a connecting hole 1421 connected to the liquid outlet hole 122 is opened on a part of the outer periphery of the plugging member 142, and the connecting hole 1421 can be connected with the liquid storage cavity 121 and the liquid outlet hole 122, so that the aerosol generating matrix in the liquid storage cavity 121 can flow from the connecting hole 1421 to the liquid outlet hole 122; a part of the outer periphery of the plugging member 142 fits with the inner wall of the liquid storage cavity 121, so that when the outer periphery of the connecting hole 1421 on the plugging member 142 fits with the inner wall of the liquid storage cavity 121, the orifice of the connecting hole 1421 is sealed by the wall surface of the liquid storage cavity 121, and the connecting hole 1421 is connected to the inner wall of the liquid storage cavity 121. The through hole 1421 is not connected to the liquid storage chamber 121. When the peripheral portion of the connecting hole 1421 on the plugging member 142 is not in contact with the inner wall of the liquid storage chamber 121, the connecting hole 1421 is connected to the liquid storage chamber 121. The plugging member 142 can be driven to move relative to the liquid outlet hole 122 by passing through one end of the switch assembly 14 outside the liquid storage member 12. The switch assembly 14 is rotated along the axial direction of the plugging member 142, and the plugging member 142 rotates accordingly, so that the connecting hole 1421 on the plugging member 142 is connected or disconnected with the liquid storage chamber 121, thereby realizing the opening or closing adjustment of the liquid outlet hole 122, and the operation method is simple. The orifices connecting the connecting hole 1421 and the liquid storage chamber 121 can be distributed on both sides of the outer periphery of the plugging member 142, so that the user can realize the switching adjustment of opening or closing the liquid outlet hole 122 by rotating the switch assembly 14 90° along the axial direction of the plugging member 142 each time.

[0051] The present application provides an external liquid storage device and an atomization system. The external liquid storage device stores liquid aerosol generating matrix and is used to supply liquid to the atomization device, so that the atomization device can additionally store the aerosol generating matrix and increase the capacity of the aerosol generating matrix.
