DETAILED DESCRIPTION

[0028] It should be noted that the embodiments in the present application and the features in the embodiments can be combined with each other without conflict. The preferred embodiments of the present application will be described in detail with reference to the drawings.

[0029] The present application provides an atomization structure, which comprises a cup body, a first shell, a second shell, a first opening, a second opening, an air vent, a liquid storage cavity, an air inlet pipe, an atomization piece, a flow guide channel, a first liquid guide channel, a second liquid guide channel, a first liquid guide groove, a second liquid guide groove, a first notch, a second notch, an atomization baffle, a limiting block, a clamping groove, a notch, a first clamping table, a second clamping table, a first guide inclined surface, a second guide inclined surface, a mist baffle ring, a positioning ring and a third guide inclined surface. Figures 1 to 7As shown, it comprises a cup body 10, an atomizing piece 20, a plurality of atomizing baffles 30 and a mist blocking ring 40. The cup body 10 forms a containing cavity with a first opening 101 and a second opening 102, which are respectively located at opposite ends of the cup body 10. A liquid storage cavity 1101 is arranged in the containing cavity. An air inlet pipe 111 is arranged on one side of the liquid storage cavity 1101 close to the first opening 101. The inlet of the air inlet pipe 111 communicates with the first opening 101. The second opening 102 communicates with the liquid storage cavity 1101. The atomizing piece 20 is arranged in the containing cavity. The atomizing piece 20 is sleeved on the air inlet pipe 111 and forms a flow guide channel 210 with the air inlet pipe 111. The inlet of the flow guide channel 210 communicates with the liquid storage cavity 1101. The outlet of the flow guide channel 210 extends to the outlet end of the air inlet pipe 111. The plurality of atomizing baffles 30 can be arranged in the containing cavity. Each atomizing baffle 30 can be detachably connected with the atomizing piece 20. A gap is formed between the atomizing baffle 30 and the outlet of the flow guide channel 210. A limiting block 310 is arranged on each atomizing baffle 30. The height of the limiting block 310 on each atomizing baffle 30 is different. The mist blocking ring 40 is arranged in the containing cavity. The mist blocking ring 40 is sleeved on the side of the atomizing baffle 30 away from the atomizing piece 20 and abuts against the limiting block 310. When the mist blocking ring 40 is arranged on different atomizing baffles 30, the distance between the mist blocking ring 40 and the outlet of the flow guide channel 210 is different.

[0030] The atomization structure of the embodiment can produce atomized particles of different particle sizes by setting multiple atomization baffles 30 and matching the mist blocking ring 40 with different atomization baffles 30 to adapt to patients of different groups. Specifically, in use, the drug solution is injected into the liquid storage cavity 1101, and the compressed air enters the air inlet pipe 111 through the first opening 101 to make the drug solution flow along the inlet of the flow guide channel 210 to the outlet of the flow guide channel 210. The drug solution ejected along the outlet of the flow guide channel 210 meets the compressed gas at the outlet of the air inlet pipe 111 at the gap, and the high-speed airflow tears and breaks the drug solution into small median particles. The median particles contact the mist blocking ring 40 to produce atomized particles, which are output along the second opening 102 for the user to use. Further, since the embodiment is provided with multiple atomization baffles 30, and the heights of the limiting blocks 310 arranged on each atomization baffle 30 are different, the mist blocking ring 40 is fixed on the atomization baffle 30 by abutting against the limiting block 310. When the mist blocking ring 40 is arranged on different atomization baffles 30, the height of the mist blocking ring 40 on the atomization baffle 30 can be changed, thereby changing the distance between the mist blocking ring 40 and the outlet of the flow guide channel 210. After the median particles are ejected from the outlet of the flow guide channel 210, they impact the mist blocking ring 40 again, and the median particles are further broken and dispersed on the mist blocking ring 40 to make the particle size smaller. Different particle sizes of atomized particles can be produced due to the different impact distances. The embodiment can be used according to patients of different groups, and only the corresponding atomization baffle 30 needs to be selected to be arranged on the atomization piece 20 to adjust the distance between the mist blocking ring 40 and the outlet of the flow guide channel 210, so that atomized particles of different particle sizes can be obtained. The use is convenient, and the atomization structure is easy to popularize and use.

[0031] With reference to Figures 5 to 7 , three examples of the limiting block 310 on the atomization baffle 30 are given, h1, h2 and h3 increase in turn. When the mist blocking ring 40 is sleeved on the atomization baffle 30, the sleeving depth of the mist blocking ring 40 on the atomization baffle 30 increases, the distance between the mist blocking ring 40 and the outlet of the flow guide channel 210 decreases in turn, the impact distance of the median particles on the mist blocking ring 40 decreases in turn, and the particle size of the atomized particles produced also decreases in turn. Therefore, the particle sizes of the atomized particles produced by the three atomization baffles 30 shown in the embodiment decrease in turn, and the user can select the corresponding atomization baffle 30 according to actual needs. Figures 5 to 7 The particle sizes of the atomized particles produced by the three atomization baffles 30 shown in the embodiment decrease in turn, and the user can select the corresponding atomization baffle 30 according to actual needs.

In the atomizer, the high-speed compressed airflow passes through the passage of the air inlet pipe 111 (similar to the throat part of a Venturi tube), and according to Bernoulli's law, the pressure at this position is lower than the ambient pressure. The drug solution is "sucked" into the flow guide channel 210 under the action of the pressure difference. Subsequently, the high-speed compressed airflow tears and breaks the drug solution into small particles at the outlet of the flow guide channel 210, thereby achieving the atomization effect.
