Ring 1104 regards the shaft shoulder as, blocks ring 1104 and pressure relief vent 603 forms and blocks cooperation；And block ring 1104 and seal disc 1101 it
Between be provided with the first sealing ring 1102, when needle seal 11 does not block nozzle 701, block ring 1104 will be to pressure relief vent
603 are blocked.If blocking without needle seal 11 to nozzle 701, then hydrojet may flow to the external world from atomization mouth 802；
Wherein, the 5th sealing ring 610 is installed in sealing hole 601, running through in the 5th sealing ring 610 has needle seal 11, the
Five sealing rings 610 can prevent hydrojet from successively flowing to the external world through pilot hole 604 and sealing hole 601, and as needle seal 11 provides axial direction
Sealing prevents hydrojet from leaking along needle seal.
Wherein, bottom plate 101 is fixed with an installing frame 104 far from the upper surface end of slideway 102；Installing frame 104 and U-shaped board
It is fixed with a support plate 105 on bottom plate 101 between 103, is fixed with switching on support plate 105 and the side plate of installing frame 104
First 6；Nozzle cap 9 is fixedly mounted on another side plate of installing frame 104.Support plate 105 and installing frame 104 are adapter 6, nozzle
Component 7, spray head sealing cap 8 and nozzle cap 9 provide the effect of limited support；Furthermore installing frame 104 and support plate 105 can be with bottom plates
101 are made into integration.
Wherein, inlet tube 606 is connected with the bottom of fluid reservoir, and the top of fluid reservoir is connected with relief tube 607, liquid storage
The hydrojet of various different viscosityes, various different mobility can be held in tank；I.e. the present invention is suitable for various different viscosityes, each
The hydrojet of the different mobility of kind.
One concrete application of the present embodiment are as follows:
When people use beauty instrument；People press pressing lever 2, and pressing lever 2 declines along slideway 102, and squeeze two
Electronic switch acts peristaltic pump and air pump；In the decline with pressing lever 2, linkage board 4 will be carried out based on U-shaped board 103
Rotation, and pull sealing needle guard 5 to move to 102 direction of slideway with the contact of guide rod 502 by guide plate 402, and spring 3 then exists
Pulling is in compressive state between sealing needle guard 5 and slideway 102, and sealing needle guard 5 at this time will drive needle seal 11 mobile, needle seal 11
Nozzle 701 will not be blocked；
And hydrojet will enter in ladder liquid collecting hole 602 through inlet tube 606, due in seal disc 1101 and the first sealing ring
1102 with the sealing function of 602 end face inner wall of ladder liquid collecting hole, therefore hydrojet flows to nozzle assembly 7, and flows out from nozzle 701；With
This simultaneously, gas successively through air inlet pipe 608, air inlet 605 and gas port 7031, enter nozzle assembly 7 and spray head sealing cap 8 it
Between in the gas chamber that is formed, and flow to the external world from atomization mouth 802, this process utilizes two fluid flow focusing technologies, to make to spray
Liquid forms stable taper after atomization mouth 802 focuses, and generates one microjet on the top of atomization mouth 802 and passes through atomization mouth
802, and be atomized mouth 802 it is outer at a certain distance from jet crushing at monodispersity droplet；
When people's release is applied to the power on pressing lever 2, under the elastic force effect of spring 3, needle guard 5 is sealed relative to cunning
Road 102 is separate, therefore sealing needle guard 5 will drive needle seal 11 to block nozzle 701, and the first sealing ring 1102 will be close
Sealing function is lost between 602 end face inner wall of closing disk 1101 and ladder liquid collecting hole；And two electronic switches then wriggle respectively by control
Pump and air pump stop working；But the gas that air pump generates will make the sky formed between nozzle assembly 7 and ladder liquid collecting hole 602
Between pressure increase, if without pressure discharge, reverse flow will be carried out in inlet tube 606 in hydrojet；When needle seal 11 with
When nozzle 70 blocks cooperation, gas will flow to fluid reservoir through pressure relief vent 603 and relief tube 607, carry out pressure release；
Two fluid ejecting device of guide rod type for being atomized instrument of the invention is made based on two fluid flow focusing technologies,
And flow focusing it is consistent, it is easy to operate, there is no harsh environment condition, the spray suitable for various viscosityes and various mobility
Liquid, market value with higher；And structure operation of the invention is simple, security performance is high, can prepare micron dimension even
The drop of hundreds of nanometers of magnitudes；Convenient for people's use, and atomizing effect is good, improves the assimilation effect of people's skin.
The device of the invention, which can be applied to, to be applied in the atomizer of beauty and skin care, medically to skin surface sprinkling drug
Equipment, paint sprayer, industry is atomized spraying apparatus, the unmanned plane of various liquid and sprays insecticide equipment and fire-fighting spraying equipment
Deng.
