For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.
[0029] Figures 1 to 8 An atomizing device in an embodiment of the present application is shown, the liquid storage bin 100 and the atomizing device can be used to prevent oil leakage, the liquid storage bin 100 comprises: a bin body 110, a liquid storage space 130 is formed in the bin body 110, the liquid storage space 130 is used to store an aerosol generating substrate, the bin body 110 comprises a liquid outlet 120, the liquid outlet 120 is arranged at one end of the bin body 110, the other end of the bin body 110 away from the liquid outlet 120 is a bin bottom 111, the liquid outlet 120 communicates with the liquid storage space 130; an air hole 200 is arranged at the bin bottom 111, the air hole 200 communicates with the liquid storage space 130; an air groove 210 is arranged on the outer wall of the bin body 110, the air groove 210 communicates with the air hole 200; and a sleeve 300 covers the air hole 200 and the air groove 210, the air groove 210 and the sleeve 300 form a capillary channel, the capillary channel communicates with the outside, and the capillary channel and the liquid storage space 130 form a communication device.
[0030] When the liquid storage tank 100 is in the upright position, the vertical height of the liquid outlet 120 is higher than the bottom 111 of the tank; when the liquid storage tank 100 is in the inverted position, the vertical height of the liquid outlet 120 is lower than the bottom 111 of the tank. The liquid storage tank 100 is installed upside down on the atomizer 420 to provide the aerosol generation matrix for the atomizer 420. That is, when the atomizer 420 and the atomizing device are in the upright position, the liquid storage tank 100 is in the inverted position; when the atomizing device is inverted, the liquid storage tank 100 is in the upright position.
[0031] By providing vents 200 and air channels 210 on the body 110 of the liquid storage tank 100, and with a casing 300 covering the bottom 111 of the tank, the casing 300 and the air channels 210 form a capillary channel, which connects the liquid storage space 130 inside the tank body 110 with the space outside the tank. When the liquid storage tank 100 is in an upright position (e.g.) Figures 1 to 7 As shown), when the atomizing device is inverted, the liquid storage space 130 and the capillary tube form a communicating vessel. The liquid storage space 130 is connected to the airflow outside the chamber through the liquid outlet 120 and maintains air pressure balance. When the air pressure or temperature outside the liquid storage chamber 100 changes, such as when the gas in the high-temperature liquid storage space 130 expands, the liquid in the liquid storage space 130 will flow out from the air hole 200 along the capillary tube and will not be discharged from the liquid outlet 120 into the atomizing component, causing oil leakage. When the liquid storage chamber 100 is in the inverted state (e.g. Figure 8 As shown), when the atomizing device is used upright, the liquid storage chamber 100 supplies oil to the atomizing components, and a negative pressure environment is formed inside the chamber 110. At this time, air flows in from the capillary tube, so that the liquid storage space 130 maintains air pressure balance. The air pressure in the liquid storage space 130 is consistent with the atmospheric pressure, which can increase the oil flow rate in the liquid storage chamber 100 and avoid clogging the core by suction.
[0032] Understandably, the liquid storage tank 100 can discharge liquid through the air hole 200, and the liquid flows along the air groove 210 to ensure that the air pressure inside the liquid storage space 130 is balanced with the external air pressure.
[0033] Understandably, the liquid in the air tank 210 is not in a state of continuous discharge. When the air pressure in the liquid storage space 130 remains stable, the liquid in the air tank 210 no longer flows but remains in a stable state. When the air pressure in the liquid storage space 130 is less than the air pressure in the external space, the liquid in the air tank 210 will be affected by the air pressure and flow back towards the air hole 200.
[0034] In one specific embodiment, the diameter of the pore 200 depends on the physical properties of the liquid and the requirements of the actual design.
[0035] In one specific embodiment, the cross-sectional area of the air groove 210 depends on the actual design requirements.
[0036] In the embodiment, the cross-sectional area of the air groove 210 is 0.3 mm x 0.3 mm.
[0037] In a specific embodiment, the air groove 210 is linearly arranged on the outer wall of the cartridge body 110. The linearly arranged air groove 210 can reduce the resistance of the liquid flowing in the air groove 210, so that the liquid can flow smoothly in the air groove 210.

In the figure, the Y direction is the longitudinal direction, and the air hole 200 penetrates the cartridge bottom 111 in the longitudinal direction. Avoiding the air hole 200 being arranged obliquely in the cartridge bottom 111, which can cause the oil liquid to be blocked.
[0039] Figure 5 As shown in the figure, in an embodiment, the cartridge body 110 can include a height direction of the cartridge body 110 as a longitudinal direction, and the air hole 200 penetrates the cartridge bottom 111 in the longitudinal direction. In the figure, the Y direction is the longitudinal direction, and the air hole 200 penetrates the cartridge bottom 111 in the longitudinal direction. Avoiding the air hole 200 being arranged obliquely in the cartridge bottom 111, which can cause the oil liquid to be blocked.
[0040] Figure 5 As shown in the figure, in an embodiment, the cartridge body 110 can include a height direction of the cartridge body 110 as a longitudinal direction, and the air hole 200 penetrates the cartridge bottom 111 in the longitudinal direction. In the figure, the Y direction is the longitudinal direction, and the air hole 200 penetrates the cartridge bottom 111 in the longitudinal direction. Avoiding the air hole 200 being arranged obliquely in the cartridge bottom 111, which can cause the oil liquid to be blocked.
[0041] As can be understood, when the liquid outlet 120 is lower than the cartridge bottom 111 in the longitudinal direction, the storage cartridge 100 is in an inverted state, as shown in FIGS. 1B and 1C. Figure 8 and Figure 3
[0042] Figure 5 The shell 300 in an embodiment can include a top shell 310 covering the outside of the air hole 200, and a side shell 320 covering the outside of the side wall, the side shell 320 being substantially flush with the second groove section 222, and the inside of the side shell 320 and the second groove section 222 forming a capillary channel.
[0043] Figure 5 The cartridge body 110 in an embodiment can include the air groove 210 being recessed inwardly from the outer surface of the cartridge body 110, or the outer surface of the cartridge body 110 being provided with a plurality of reinforcing ribs protruding outwardly, the air groove 210 being formed between the reinforcing ribs, and the reinforcing ribs being connected with the inner wall of the shell 300 to form the capillary channel. The reinforcing ribs are connected with the inner wall of the shell 300 to form a side gap, and the outer wall of the shell 300 and the reinforcing ribs form a corresponding circumferentially closed channel, so that the liquid can flow upwardly in the air groove 210.
[0044] In a specific embodiment, the air groove 210 and the shell 300 abut each other, the size of the air groove 210 is greater than the size of the inner wall of the shell 300, and the air groove 210 and the shell 300 are in interference fit.
[0045] Further, the air groove 210 and the shell 300 are fixed by riveting.

[0047] In a specific embodiment, the number of air grooves 210 is less than the number of air holes 200, the air grooves 210 are connected with one or more air holes 200, or the number of air grooves 210 corresponds to the number of air holes 200, and each air groove 210 is connected with one air hole 200. A single air groove 210 can be connected with one air hole 200, but the air groove 210 can also be connected with a plurality of air holes 200 at a time, which needs to be set according to actual needs.
[0048] Further, when a single air groove 210 is connected with a plurality of air holes 200, the cross-sectional area of the air groove 210 is greater than the area of a single air hole 200, so that the air groove 210 can simultaneously discharge the liquid of the plurality of air holes 200 without being blocked.

When the storage tank 100 is installed in the atomizer 420, the shape of the storage tank 100 matches the shape of the inside of the atomizer 420, which can reduce the volume of the atomization device and increase the capacity of the storage tank 100.
