The air blowing device 6 includes an air supply device and a bottom plate 61, and the air supply device is connected to the bottom plate 61.

[0030] In one embodiment, a plurality of connectors 611 are correspondingly arranged on opposite sides of the chassis 61. Specifically, the chassis 61 is connected to the gas supply device through the connector 611, and the gas supply device transmits gas to the inside of the chassis 61 through the connector 611. A positioning member 612 is also arranged on the chassis 61 to facilitate the rapid positioning of items placed on the chassis 61.

[0031] In one embodiment, the air supply device further includes a filter device 63 and an air conditioning device 62, and the connector 611 of the chassis 61, the air conditioning device 62 and the filter device 63 are sequentially connected through an air guide pipe 64. Specifically, the air blowing device 6 is provided with two groups of air supply devices, and a plurality of connectors 611 on one side of the air conditioning device 62 are connected to a corresponding group of air supply devices, and the plurality of connectors 611 are connected to the air supply device through the air guide pipe 64.

[0032] The gas regulating device 62 is used to adjust whether to supply gas to the chassis 61 according to production requirements. The filtering device 63 is used to filter the gas in the gas supply device to prevent impurities in the gas from affecting the product quality of the atomizing device.

[0033] The liquid injection system is provided with a tray 7, which is arranged on the bottom plate 61. Specifically, the tray 7 is arranged on the top of the bottom plate 61 in a corresponding overlapping manner. The tray 7 includes a plurality of receiving holes 71 for receiving the liquid storage component. The end of the liquid storage component close to the cigarette holder is placed in the receiving hole 71, and the end of the liquid storage cup opening is away from the receiving hole 71. The tray 7 is also provided with a through hole, which is arranged below the receiving hole 71. The through hole and the receiving hole are coaxially arranged and pass through the tray 7. Specifically, the size of the receiving hole matches the size of the liquid storage component, and the size of the through hole is smaller than the receiving hole 7. On the one hand, such a setting ensures that the liquid storage component will not fall from the tray, and on the other hand, it also unblocks the blowing channel. The gas provided by the air supply device reaches the liquid storage component through the bottom plate 61 and the receiving hole 71. In this embodiment, ten receiving holes 71 are arranged in a row on the tray 7, which can accommodate ten atomization devices. The receiving holes 71 can be arranged in multiple rows, and other embodiments are not limited.

[0034] The liquid injection system further includes a cover plate 8, which is stacked on the tray 7. The cover plate 8 includes a plurality of air baffles 81 and penetration holes 82. The plurality of air baffles 81 are arranged corresponding to the receiving holes 71, and each air baffle 81 is coaxially arranged with a corresponding liquid storage component placed in the receiving hole 71, and in particular, is coaxially arranged with the air outlet pipe 4 of the liquid storage component. The penetration holes 82 are arranged on both sides of the air baffle 81, corresponding to the liquid storage on both sides of the air outlet pipe 4 placed in the receiving hole 71, for allowing a corresponding group of liquid injection parts to pass through.

[0035] In one embodiment, the air blocking member 81 can directly cover the bottom surface of the reduced diameter portion 41. In another embodiment, the liquid storage assembly includes a connecting member 5, the connecting member 5 is connected to the reduced diameter portion 41, and the air blocking member 81 covers the bottom surface of the connecting member.

[0036] The injection device 9 is connected to the liquid supply device through a pipeline 93. The injection device 9 includes at least one group of injection parts 91 with a hollow structure, which is used to inject the liquid in the liquid supply device into the liquid storage. The injection device 9 also includes a support frame 95 for supporting the injection part 91. Specifically, the injection part 91 can be an injection needle, and each group of injection parts 91 can include two injection needles, and the two injection needles are arranged side by side on the fixed frame 92. When injecting liquid, the two side-by-side injection needles can be inserted into the liquid storage of the same liquid storage component at the same time, and the liquid storage on both sides of the vent pipe 4 is injected with liquid, so as to promote uniform injection. In addition, in order to improve the injection efficiency, multiple groups of injection parts 91 can be set at the same time to inject liquid into multiple liquid storage components at the same time. In this embodiment, the injection device 9 preferably uses five groups of injection parts 91, each group of injection parts 91 corresponds to a separate fixed frame 92, and the support frame 94 connects the five groups of injection parts 91, and the support column 95 supports the connection of the five groups of injection parts 91 and the support frame 94.

[0037] The liquid injection system further includes a lifting mechanism (not shown in the figure) and a control device (not shown in the figure). The liquid injection device 9 is arranged on the lifting mechanism, and the lifting mechanism can carry the liquid injection device 9 down to insert into the liquid storage or up to remove from the liquid storage. The control device is connected to the lifting mechanism and the liquid supply device, and is used to control the lifting action of the lifting mechanism and control the liquid supply device to provide liquid medium to the liquid injection part 91.

[0038] The present invention uses an air baffle 81 in the cover plate 8 on the liquid storage component to press the air outlet pipe 4 or the connecting member 5, so that the blowing device 6 blows air upward to the air outlet pipe 4 through the accommodating hole 71. The blown gas will form an outward gas flow from the notch of the reduced diameter portion. In this way, the force applied by the injection needle when inserting the liquid storage device to inject liquid will be reduced by the force of blowing from the inside to the outside, thereby achieving the effect that the liquid will not overflow from the liquid storage device to the air outlet pipe 2 and then flow to the suction nozzle 1.

[0039] The present invention also provides a liquid injection method using the above liquid injection system, comprising the following steps: S1, placing the liquid storage assembly into the receiving hole 71 of the tray 7. In some embodiments, the side of the air outlet pipe 4 close to the suction nozzle is placed at the bottom of the receiving hole 71, and the side of the air outlet pipe 4 close to the opening of the liquid storage cup faces the top of the receiving hole 71.

[0040] S2, placing the tray 7 on the blowing device 6. Specifically, the blowing device 6 includes an air conditioning device 62, and the tray 7 is placed on the air conditioning device 62, and the positioning member is used to achieve rapid positioning, and the air conditioning device 62 and the tray 7 are overlapped. When the liquid injection is completed, the next tray 7 with the liquid storage component placed thereon can be directly replaced.

[0041] S3, place the cover plate 8 on the tray 7 to press the liquid storage assembly. In one embodiment, the air stopper 81 on the cover plate 8 presses the bottom surface of the reduced diameter portion 41 of the air outlet pipe 4. In another embodiment, the air stopper 81 can also press the bottom surface of the connector connected to the reduced diameter portion 41.

[0042] S4, start the blowing device 6, and let the blowing device 6 blow air to the receiving hole 71. In one embodiment, the filter device 63 will first filter the gas, and send the impurity-free gas to the gas regulating device 62 through the air guide pipe. After starting the blowing device 6, the gas regulating component is in an open state, and the gas is sent to the gas regulating device 62 through the connector 611. The gas reaching the gas regulating device 62 will enter the gas outlet pipe 4 from the bottom of the receiving hole 71, and reach the end of the gas outlet pipe 4 close to the opening of the liquid storage cup from the end of the gas outlet pipe 4 close to the suction nozzle.

[0043] S5. Start the liquid injection device 9 to inject the liquid in the liquid supply device into the liquid storage. In one embodiment, after starting the liquid injection device 9, the liquid in the liquid supply device is transferred to the liquid injection part 91 through the pipeline, and two liquid injection needles of a group of liquid injection parts 91 respectively pass through the two penetration holes 82 of the cover plate 8, and the liquid injection needles are inserted into the liquid storage assembly placed in the receiving hole 71 below the cover plate 8. Specifically, the two liquid injection needles respectively pass through the liquid storage on both sides of the air outlet pipe 4.

[0044] Since air is kept flowing into the air outlet pipe in the liquid storage component, the liquid medium is prevented from flowing from the liquid storage into the air outlet pipe during liquid injection, thereby solving the oil leakage problem, reducing the manpower for cleaning the oil leakage, and improving the product quality.
