Detailed Description
The invention will be further elucidated and described with reference to the following embodiments and drawings in which:
referring to fig. 1 and 2, the nozzle includes a nozzle body 10, an atomizing chamber 11, a gas chamber 12 and a liquid chamber 13 are formed in the nozzle body 10, the atomizing chamber 11, the gas chamber 12 and the liquid chamber 13 are all communicated with the outside, the gas chamber 12 and the liquid chamber 13 are all communicated with the atomizing chamber 11, and a leakage-proof device 14 is disposed in the liquid chamber 13.
Compressed gas is introduced into the gas cavity 12, the liquid cavity 13 is communicated with liquid to be mixed and atomized through a pipeline, and under the driving of the compressed gas, a Bernoulli effect is generated inside the atomization cavity 11 to form negative pressure.
The leakage-proof member 142 is moved by the gas toward the atomizing chamber 11 under the action of the negative pressure, so that the elastic member 141 is stretched to communicate the liquid chamber 13 with the atomizing chamber 11, so that the liquid is sucked into the liquid chamber 13 under the action of the negative pressure, enters the atomizing chamber 11 through the liquid chamber 13, is mixed with the gas in the atomizing chamber 11, and is ejected out of the atomizing chamber 11 through the pressure in the atomizing chamber 11, thereby forming the condition of water mist.
When people remove the compressed gas from the gas cavity 12, the bernoulli effect in the atomizing cavity 11 disappears, so that the leakage-proof member 142 is pulled back to the end close to the liquid cavity 13 by the elastic member 141 under the action of losing the negative pressure, the leakage-proof member 142 and the liquid cavity 13 are in interference fit again, the liquid cavity 13 is sealed, and the liquid is prevented from flowing out from the liquid cavity 13 continuously.
In the above scheme, the elastic member 141 is a spring or a rubber rope, which can prevent the liquid chamber 13 from being blocked by the elastic member 141, and can maintain the tension of the leakage-proof member 142.
The leakage preventing member 142 is spherical, and the diameter of the leakage preventing member 142 is larger than that of the outlet of the liquid chamber 13, so that the gap between the surface of the leakage preventing member 142 and the outlet of the liquid chamber 13 is reduced when the surface of the leakage preventing member is in contact with each other. The leakage prevention member 142 may be made of an elastic material, so that the leakage prevention member 142 can be better attached to the liquid chamber 13 when being in interference fit with the liquid chamber 13, thereby preventing leakage.

When the liquid in the liquid chamber 13 is passed through the accelerating ring 131, an accelerating effect is produced by passing the liquid from the large diameter pipe through the small diameter pipe, thereby accelerating the flow of the liquid from the liquid chamber 13.
The atomizing cavity 11 is tapered at the side far away from the gas cavity 12, and the atomizing cavity 11 is gradually reduced from one end of the gas cavity 12 along the axial direction. After gas and liquid mix in atomizing chamber 11, when spouting from atomizing chamber 11, atomizing chamber 11's export becomes the convergent to make the mixture of gas and liquid receive an extruded effect, thereby play an effect of accelerating the blowout, make the atomization effect better.
The utility model provides a gas water atomizing nozzle lets in compressed gas in the gas chamber, and the liquid chamber communicates through pipeline and the liquid that needs mix the atomizing, and under compressed gas's drive, the inside bernoulli effect that produces of atomizing chamber forms the negative pressure. Be equipped with leak protection device in the liquid chamber, leak protection device includes elastic component and leak protection piece, elastic component one end and liquid intracavity wall fixed connection, the elastic component other end and leak protection piece fixed connection, leak protection piece sets up and is close to atomizing chamber one end in the liquid chamber, leak protection piece is under the effect of negative pressure, by gaseous towards the motion of atomizing chamber, thereby stretch the elastic component, make liquid chamber and atomizing chamber communicate, thereby liquid is inhaled in the liquid chamber under the effect of negative pressure, entering into the atomizing chamber through the liquid chamber, mix with the gas in the atomizing chamber, spout in the atomizing chamber is followed to pressure in the rethread atomizing chamber, thereby form the condition of water smoke.
