[0023] The technical solution of the present invention will be further described below with reference to the accompanying drawings.

[0024] See also Figure 1-2 As shown, the above-mentioned atomizing device includes: Figure 1 The cap body 1 and cylinder body 2 are connected in sequence (in the direction of the center), the air inlet pipe 3 is fixedly inserted into the cap body 1, and the gas-liquid conductive sleeve 4 is fixedly inserted into the cylinder body 2. The cylinder body 2 is coaxially connected to the open end of the cap body 1, that is, the lower end of the cap body 1. The air inlet pipe 3 is fixedly inserted into the end cap of the cap body 1. In this embodiment, the upper end of the air inlet pipe 3 extends upward through the cap body 1, while the lower end of the gas-liquid conductive sleeve 4 extends downward through the cylinder body 2. The cap body 1, cylinder body 2, air inlet pipe 3, and gas-liquid conductive sleeve 4 are coaxially arranged.

[0025] See also Figure 1 As shown, the gas-liquid conducting sleeve 4 comprises an inner sleeve 41 whose upper end communicates with the lower end of the air inlet pipe 3, an outer sleeve 42 fixedly sleeved on the outside of the inner sleeve 41 and extending through the lower end of the barrel 2, and a first annular liquid inlet cavity 43 defined between the inner and outer sleeves 41, 42. Specifically, an annular gap is defined between the outer circumference of the inner sleeve 41 and the inner circumference of the outer sleeve 42. In this embodiment, the inner and outer sleeves 41, 42 are coaxially arranged.

[0026] The outer sleeve 42 is abutted against the cylinder 2 along its circumferential side. The outer sleeve 42 includes a concave ring 44 annularly recessed on its outer circumference, and a plurality of first liquid inlets 45 opened on the concave ring 44 and connected to the first annular liquid inlet cavity 43.

[0027] In this embodiment, the outer diameter of the outer sleeve 42 is the same as the inner diameter of the barrel 2. A plurality of first liquid inlets 45 are arranged in a ring-shaped manner at regular intervals on the concave ring 44. Through this arrangement, the liquid in the concave ring 44 can enter the first annular liquid inlet cavity 43 simultaneously and evenly through the plurality of first liquid inlets 45.

[0028] The above-mentioned atomizing device further includes a second annular liquid inlet chamber 5 provided between the concave ring 44 and the barrel 2, and a second liquid inlet port 6 provided on the barrel 2 and communicating with the second annular liquid inlet chamber 5. Liquid is input into the second annular liquid inlet chamber 5 through the second liquid inlet port 6, so that the liquid in the second annular liquid inlet chamber 5 can simultaneously and evenly enter the first annular liquid inlet chamber 43 through the multiple first liquid inlet ports 45.

[0029] The aforementioned atomizing device further includes a Venturi atomizing nozzle 7, which is connected to the lower end of the inner sleeve 41 and is located in the first annular liquid inlet chamber 43; and a nozzle 8, which is fixed to the extended end of the outer sleeve 42 and connected to the Venturi atomizing nozzle 7. The Venturi atomizing nozzle 7 is used to generate negative pressure when gas passes through it, and to draw liquid from the first annular liquid inlet chamber 43, thereby achieving uniform mixing of gas and liquid and small atomized particles. In this embodiment, the nozzle 8 is threadedly connected to the extended end of the outer sleeve 42.

[0030] See also Figure 1 As shown, in this embodiment, the Venturi atomizing nozzle 7 is provided with a first through hole 71, whose upper and lower ends respectively communicate with the lower end of the inner sleeve 41 and the upper end of the nozzle 8, and a liquid suction hole 72 for connecting the first through hole 71 with the first annular liquid inlet chamber 43. The liquid suction hole 72 connects the first through hole 71 and the first annular liquid inlet chamber 43 in the left-right direction. The first through hole 71 gradually contracts in a direction away from the inner sleeve 41 (i.e., from top to bottom), then remains unchanged, and then gradually expands. The left end of the liquid suction hole 72 is connected to this expansion section.

[0031] See also Figure 1 As shown, in this embodiment, the nozzle 8 is provided with a second through hole 81 communicating with the first through hole 71 , and the first through hole 71 and the second through hole 81 have the same axis.

[0032] The air inlet pipe 3 is used to introduce pressure-adjustable gas. By adjusting the gas pressure in the air inlet pipe 3, the atomization effect can be adjusted as needed to achieve efficient atomization.

[0033] The above-mentioned atomizing device further includes a sealing ring 9 provided between the cap body 1 and the barrel body 2, and a fixing bolt 10 for sequentially connecting the cap body 1, the sealing ring 9 and the barrel body 2. By providing the sealing ring 9, the sealing between the cap body 1 and the barrel body 2 can be ensured.

[0034] The above-mentioned atomizing device further includes a sealing sleeve 11 disposed inside the sealing ring 9 and abutting between the inner end surface of the cap body 1 and the upper end of the gas-liquid transmission sleeve 4. The sealing sleeve 11 is sleeved on the air inlet pipe 3. The provision of the sealing sleeve 11 ensures the sealing between the cap body 1 and the gas-liquid transmission sleeve 4.

[0035] See also Figure 1 As shown, the sealing sleeve 11 and the nozzle 8 are respectively used to block the axial ends of the first annular liquid inlet cavity 43. That is, the sealing sleeve 11 is used to block the upper end of the first annular liquid inlet cavity 43, and the nozzle 8 is used to block the lower end of the first annular liquid inlet cavity 43.

[0036] The working process of this embodiment is described in detail below:

[0037] The liquid enters through the second liquid inlet 6 on the cylinder 2 and flows into the first annular liquid inlet cavity 43 along the second annular liquid inlet cavity 5 between the cylinder 2 and the gas-liquid conductive sleeve 4 .

[0038] During atomization, gas with a certain pressure is introduced from the air inlet pipe 3 and enters the atomizing nozzle through the inner sleeve 41. The liquid in the first annular liquid inlet cavity 43 is sucked into the atomizing nozzle through the small liquid suction hole 72 opened on the atomizing nozzle, and is mixed and atomized and then sprayed out through the nozzle 8.

[0039] The pressure of the external gas is adjustable. Since the pressure in the first annular liquid inlet cavity 43 remains substantially unchanged, different atomization effects can be achieved by adjusting the gas pressure.

[0040] The above embodiments are intended only to illustrate the technical concepts and features of the present invention. Their purpose is to enable those skilled in the art to understand the contents of the present invention and implement them accordingly. They are not intended to limit the scope of protection of the present invention. Any equivalent changes or modifications made in accordance with the spirit of the present invention are intended to be covered by the scope of protection of the present invention.
