In figure：100 liquid caps, 101 fluid chambers, 102 air inlets, 1001 interconnecting pieces, 1002 spray chambers, 120 air cavitys, 200
Air cap, 201 first air cavitys, 202 second air cavitys, 203 fumaroles, 204 convex blocks, 205 nozzles.
Specific implementation mode
The utility model is further described below in conjunction with the accompanying drawings：
As shown in Figs. 1-3, the utility model is made of liquid cap 100 and air cap 200.100 one end side of liquid cap
Evagination forms interconnecting piece 1001, and the other end is to central reduction.Liquid cap 100 leads to structure in being, internal is fluid chamber 101, liquid
101 one end of body cavity is the same end to contract and aforementioned serrated end, which is spray chamber 1002；In the company of liquid cap 100
It is air inlet that socket part 1001, which is equipped with axial pass-through holes,.
Air cap 200 is concave inward structure, and the bottom end of female parts offers nozzle 205, what is enclosed around nozzle 205 1
Part convexes to form convex block 204.
Liquid cap 100 is connect by interconnecting piece 1001 with spray chamber 1002 with air cap 200, the two connection after, the two it
Between to form space be air cavity 120, which communicates with air inlet 102；In 120 one end of air cavity by the convex block 204 of annular
It is separated into two parts, respectively the first air cavity 201 and the second air cavity 202.Spray chamber 1002 is arranged in nozzle 205, spray chamber
1002 outer diameters are less than 205 internal diameter of nozzle (1002 outer diameter of spray chamber includes its chamber wall thickness herein).
A kind of situation is that liquid cap 100 is made of liquid cap mold insert and liquid cap pedestal.Liquid cap pedestal includes " connection
Portion 1001, air inlet 102 and the institute of fluid chamber 101 " are 100 right half of liquid cap, liquid cap mold insert and liquid at one end and locular wall
Cap pedestal is detachable connection, installation production of being more convenient for (wherein, left and right directions is by taking Fig. 1 as an example).
First air cavity 201 is communicated with nozzle 205；Second air cavity 202 with the fumarole 203 in 200 bottom of air cap is set
It communicates.Fumarole 203 is one or more, but is symmetrical arranged centered on nozzle 205.And fumarole 203 is outer mixed with this
The axis shape of type atomizer is at a certain angle, which is formed such that the gas projected from fumarole 203 is inside, and energy
It enough converges on the axis of external mixing type atomizer.
It is equipped with sealing element in liquid cap 100 and 200 connecting portion of air cap, it is preferred that the two is connected through a screw thread.
As can be seen from Figure 2, the setting of fluid chamber 101 starts at 100 middle part of liquid cap, air inlet 102 in 100 one side of liquid cap
Side, and fluid chamber 101 is convex is easily installed water pipe in end face.
As can be seen from Figure 3, fumarole 203, which opens up, sets in 200 bottom of air cap, and nozzle 205 is centrally disposed, and liquid cap
100 spray chamber 1002 is connected to the inside of 200 bottom surface of air cap.
Air inlet 102 and fluid chamber 101 phase are independent, specifically, the two is not interconnected directly, and in actual use without
Connection interactive relation need to be formed between the two.
200 agent structure section of air cap is " M " type；200 agent structure of air cap is to remove the entirety of convex block 204, is cutd open
Face is axial section, is splitted from center.Specifically, air cap 200 is the structure that a both ends are recessed inwardly, but it is recessed
Mode is different, referring specifically to attached drawing 1.
Spray chamber 1002 in nozzle 205 can stretch out 200 bottom end of air cap.It is emphasized that in the utility model
Gas gap between spray chamber 1002 and nozzle 205 is projected in air cavity 120.
A kind of working method of the utility model is：
After the utility model is installed as described above, water pipe is connected in 100 right end of liquid cap, water pipe applies external pressure, specifically
For, which communicates with fluid chamber 101, and air inlet 102 connects tracheae.To the nozzle water flowing and compressed gas.In water pipe
Water is reached by fluid chamber 101 shrinks position, subsequently into spray chamber 1002.
This simultaneously, compressed gas in tracheae enters air cavity 120 after air inlet 102, reaches the 204 top time-division of convex block
It flows at two, wherein the gas into the first air cavity 201 eventually enters into nozzle 205, is projected from nozzle 205.With from spray chamber
1002 project water mixing, and by water initial atomization, external pressure is smaller in water pipe, is insufficient to allow the water column of injection not mixed with air column, water
Column forms vacuum suction mixing by air-flow.
The gas of another above-mentioned flow direction enters the second air cavity 202, into after the second air cavity 202, reaches 200 bottom of air cap
The fumarole 203 in portion, is projected from fumarole 203.
Due to the special setting angle of fumarole 203, the gas projected from fumarole 203 is and preliminary from 205 mouthfuls of nozzle
Atomized water converges, and gas further makes water fogging in fumarole 203, and since this is engraved in nozzle exterior atomization, and jet
Hole 203 to axle center setting (wherein in order to make fumarole 203 to axle center be arranged, 200 bottom surface of air cap also be concave inward structure,
I.e. its main body is " M " type, and axle center is nozzle shaft position), water and non-parallel is projected with nozzle 205, can be given after outlet
The power of liquid transverse direction after atomization makes water mist form laterally fan-shaped water mist so that the water after atomization possesses the diffusingsurface of bigger.Wherein
1002 water outlet of spray chamber may be configured as 0.2mm diameters, can make atomizing particle smaller.
Another way is that specially applying external pressure, water are not communicated with air water pipe by gravity flowing, fluid chamber 101 yet,
When reaching spray chamber 1002, the air-flow in the first air cavity 201 is projected from nozzle 205 and 1002 clearance space of spray chamber, makes spray
1002 oral area of water cavity forms negative pressure, to which the water in fluid chamber 101 is constantly sucked out from spray chamber 1002 using siphon principle,
And then with air-flow mixed aerosol.Other principles are identical as above-mentioned water pipe application external pressure situation.
" M " type air cap 200 enables 203 vertical bottom face of fumarole to be arranged, and reduces difficulty of processing, meanwhile, vertically set
The fumarole 203 set possesses better outlet effect.
Due to setting, there are two air cavity and fumarole 203, the problems that 120 air pressure inside of air cavity will not be caused excessive, also into one
Step solves the problems, such as liquid reflux, while when nozzle 205 blocks, will not cause danger because pressure is excessive.
Meanwhile it being equipped with after cushion chamber can make gas enter air cavity 120 top of air cavity (i.e. with 102 adjacent end of air inlet)
There are one bufferings, when air-liquid preferably being avoided to enter asynchronous, the problem of then liquid enters air cavity due to air pressure problem.Tool
Body is in order to avoid air inlet 102 is arranged behind side, ventilation, and side air pressure conference makes 1002 side air pressure of spray chamber be more than
The other side, so as to make internal water enter air cavity 120 from side.
Since connecting portion is equipped with sealing element and will not cause outside gas and liquid between liquid cap 100 and air cap 200
The case where letting out.Wherein interconnecting piece 1001 is equipped with matched screw thread with 200 port part of air cap, and the two, which combines, makes air cavity 120
Sealing effect is more preferable.
It is to reduce gas as far as possible that air cavity 120, which is divided into two parts without directly using an air cavity, by convex block 204
120 volume of chamber.Installation position is designed using annular knurl, is more convenient for installing.
In addition, the utility model is not limited to the above embodiment, as long as it reaches this reality with essentially identical means
With novel technique effect, it should all belong to the scope of protection of the utility model.
