Specific implementation mode
Invention is further explained below in conjunction with the accompanying drawings：
As shown in Figs. 1-3,100 axial cross section of liquid cap be T-type, main body be in lead to structure, in lead to part be fluid chamber
101；The side evagination on 100 top of liquid cap forms interconnecting piece 102, and interconnecting piece 102 is equipped with the air inlet 103 of perforation；Fluid chamber
101 and air inlet 103 be axially through.Spray chamber 1011 is connected after being received in 101 lower part of fluid chamber, is led in spray chamber 1011
Part is atomization chamber 1012, and 1011 side wall of spray chamber offers through-hole, which is air flue 3010.
Gas cap 200 is barrel shape, and bottom surface indent offers connector in the middle part of bottom surface, and protrusion is equipped with around connector
Guide pad 201.
Interconnecting piece 102 is connected to 200 upper end oral area of gas cap, and 1011 outer wall of spray chamber connects the company of 200 bottom surface of gas cap
Interface, and preferably through threaded connection.
Gas cap 200 is connect with liquid cap 100, and connecting portion is equipped with sealing element；Air cavity 300, gas are formed between the two
The lower part of chamber 300 is directed to block 201 and is separated into the first air cavity 301 and the second air cavity 302.Second air cavity 302 and 200 bottom of gas cap
Face connecting portion offers fumarole 303, and fumarole 303 runs through 200 bottom surface of gas cap.First air cavity 301 passes through air flue 3010
Atomization chamber 1012 is connected, and air flue 3010 is tilted down from first port 3011 to second port 3012.Air flue 3010 and atomization
1012 locular wall angle a of chamber is acute angle, preferably less than 45o.When angle a is less than 45o, gas is after the injection of air flue 3010, energy
It is preferably flowed to nozzle 1013, is not easy to play a reversed role into fluid chamber 101.Fumarole 303 is generally multiple, and is with nozzle 1013
Center symmetric setting.
3010 flow at high speed gas of atomization chamber flows downward so that negative pressure is formed at 3010 top of atomization chamber, so as to incite somebody to action
Liquid in fluid chamber 101 is sucked out.It is equipped with separation net 10,10 energy of separation net in fluid chamber 101 and 1012 connecting portion of atomization chamber
It is enough by by droplet segmentation smaller.
Fumarole 303 is arranged on inclined bottom surface, and central shaft is not flat with fluid chamber 101 or 1012 central shaft of atomization chamber
Row.Fumarole 303 projects the central shaft that gas converges at fluid chamber 101, is converged with the flow projected from nozzle 1013, thus into
One step atomization flow.Simultaneously as corner cut exists so that flow is moved horizontally by the gas drive projected from fumarole 303, from
And a fan-spray is formed, increase spray area, the cooperation of multiple fumaroles 303 can possess better effect.
The present invention a kind of working method be：
101 top of fluid chamber is by screw thread water receiving pipe, and 103 top of air inlet is by screw thread trachea, and then water supply is to gas.
Flow reaches it after fluid chamber 101 and shrinks position.
In the case where hydraulic pressure is larger, flow reaches atomization chamber directly through separation net 10；It needs in the case that hydraulic pressure is smaller
Negative pressure is formed in atomization chamber 1012, then water in fluid chamber 101 is sucked out；Pass through separation net 10 and smaller atomization chamber 1012
Internal diameter can make water in fluid chamber 101 be not easy voluntarily to drip, and by the cooperation of atomization chamber negative pressure, reaching only needs by controlling air-flow
The atomizing effect of whole equipment can be controlled.
Gas reaches the cushion chamber on air cavity 300 top by air inlet 103, and then enter the first air cavity 301 and the respectively
Two air cavitys 302；Atomization chamber 1012 is entered by air flue 3010 after into the first air cavity 301, since 3010 tilting of air flue designs,
Air-flow is projected to nozzle 1013 well, then forms negative pressure on 1012 top of atomization chamber.This design, but also high
Body of calming the anger is not easily accessible fluid chamber, is mutually gone here and there so as to avoid gas-liquid.
Meanwhile it being equipped with after cushion chamber can make gas enter air cavity 300 top of air cavity (i.e. with 103 adjacent end of air inlet)
There are one bufferings, when air-liquid is asynchronous into the problem of fashionable, energy buffering air pressure difference causes liquid to enter air cavity.The tool of cushion chamber
Body acts on：Avoid 103 side of air inlet after ventilation, this side air pressure is more than the other side, this side air pressure of atomization chamber 1012 is more than another
Side enters the first air cavity 301 to generate 1012 internal water of pressure official post atomization chamber.
It is divided into smaller droplet across the liquid of separation net 10, the gas projected with air flue 3010 is together from nozzle
It projects.The gas of the second air flue 302 is projected from fumarole 303 at this time, and gas-liquid mixture convergence is projected with from nozzle 1013, to
Gas further impacts water mist, and water is further atomized.The gas that fumarole 303 projects has the power of horizontal direction, can make water
Mist has the distribution area of bigger.
Due to being equipped with the first air cavity 301 and the second air cavity 302 and multiple fumaroles 303, will not cause inside air cavity 300
The excessive problem of air pressure, the problem of also further solving liquid reflux, while when nozzle 1013 blocks, it will not be because of pressure
It is excessive and cause danger.
Air flue 3010 and the angle a of atomization chamber 1012 are acute angle, further can be less than 45o.
303 central shaft outlet of fumarole, the place refer to central shaft and refer to 101 central shaft of fluid chamber and fumarole 303 in
Mandrel is not arranged in parallel, in the angle less than 90o so that water can be projected with from nozzle 1013 by projecting gas from fumarole 303
Column converges at 101 central shaft of fluid chamber.Wherein, fluid chamber 101, the central shaft of atomization chamber 1012 are conllinear.
200 agent structure of gas cap is not include the part of guide pad 201, and agent structure is splitted along rotation axis
Cross-section profile is " M " type that falls.Its structure specifically barrel shape, and bucket bottom indent, as shown in Figure 1, interior upwards in the middle part of bucket bottom surface
It is recessed.
In the Fig. 1 of " upper and lower, left and right " described herein subject to direction, it is for becoming apparent from statement, has no other
Particular meaning.
In addition, the invention is not limited in the above embodiments, as long as it reaches the present invention's with essentially identical means
Technique effect should all belong to the scope of protection of the present invention.
