Corresponding steam vents 126 configurations of loam cake 122 and be connected in the end face of lower cover 121,130 of filter materials are installed in loam cake 122, filter material 130 is in order to filter envelope steam vent 126, loam cake 122 and filter material 130 are the object of additivity function, it is done bacteriological filtration at patient expired gas and uses, and can install additional in response to user demand.

Spray structure 200 is embedded at the bottom of stack shell 110, and medicine mist generator 200 is fixedlyed connected with stack shell 110 with snap fit, but does not exceed with this kind connection means.

Spray structure 200 comprises an awl post 210, a cone-shaped hood 220, reaches a block 230.

To chamber 111 punch formings, form in the recess side of awl post 210 has a Compressed Gas passage 211 to awl post 210 by the interior diapire of stack shell 110, and the top of awl post 210 offers the Compressed Gas inlet 212 that is communicated with chamber 111 and Compressed Gas passage 211.

Cone-shaped hood 220 is penetration state, and cone-shaped hood 220 is arranged at the convex side outside of awl post 210, and cone-shaped hood 220 is formed with a fluid passage 221 with boring space slight distance between the post 210 again.

The passway of corresponding Compressed Gas inlet 212 of block 230 and fluid passage 221 and be arranged at cone-shaped hood 220 and awl post 210 tops.

Pressing mechanism 300 comprises a cylinder base 310 and a press component 320.

Cylinder base 310 comprises an appendix 311, a relief hole 312, reaches a pivot portion 313.

Appendix 311 is plugged in Compressed Gas passage 211, relief hole 312 connects appendix 311, and the aperture center line of relief hole 312 and the pipeline axial line of appendix 311 are mutually orthogonal, the aperture size of relief hole 312 is greater than the aperture size of Compressed Gas inlet 212 again, and 313 in pivot portion takes shape in cylinder base 310 peripheries of relief hole 312 sides.

Press component 320 comprises pulls arm 321, a valve 322, an and elastic arm 323.

Pull arm 321 and be articulated in pivot portion 313, arm 321 extends valve 322 and corresponding relief hole 312 positions set and can open and close by corresponding relief hole 312 from pulling, elastic arm 323 is connected in to pull arm 321 and support and is affixed on stack shell 110, pull arm 321, valve 322, and elastic arm 323 can be formed in one, to simplify fabrication schedule and to reduce manufacturing cost and promote structural strength, elastic arm 323 can also with pull arm 321 and be connected for combination type, reach broader flexible application category, pull arm 321 again and form a compacting bar 324, compacting bar 324 is in order to the periphery wall of compacting elastic arm 323.

Use this utility model to make the medicine mist so that the method for suction to be provided, please refer to Fig. 4 to shown in Figure 7, at first a medicament 400 is filled and store in chamber 111, medicament 400 is used for the treatment of the disease of human body, the liquid level of medicament 400 is no more than Compressed Gas inlet 212, and in the medicament 400 meeting incoming fluid passages 221.

Pour into a Compressed Gas 500 from appendix 311, in general Compressed Gas 500 is a compressed oxygen, Compressed Gas 500 reaches 211 circulations of Compressed Gas passage in appendix 311, when sufferer need be inhaled medicine, pull arm 321 this moment, pull arm 321 and rotate and drive valve 322 sealing relief holes 312, and, make its deflection deformation and the storage elasticity restoring force simultaneously with compacting bar 324 compacting elastic arms 323 peripheries by pivot portion 313.

When the close relief hole 312 of valve 322 envelopes, Compressed Gas 500 unique flow paths only enter in the Compressed Gas passage 211 for the appendix 311 of flowing through again, Compressed Gas 500 then enters littler Compressed Gas inlet 212 from Compressed Gas passage 211, venturi-effect can take place, and promptly Compressed Gas 500 is with medicament 400 sucking-off from fluid passage 221.

Compressed Gas 500 attracts medicaments 400 and impacts medicament 400 and make its refinement, medicament 400 after the refinement is compressed gas 500 and sprays to and clash into block 230, making its splash atomizing and mixing with Compressed Gas 500 is that a medicine mist 600 is sent forth towards periphery, and medicine mist 600 major parts can be filled in the inlet channel 123.

Sufferer is stung with oral area and is clamped protruding pipe 113, and air-breathing medicine mist 600 in the inlet channel 123 is sucked pulmonarys via chamber 111, mixed-gas channel 129, mixed gas outlet 112, and the inspiratory force of sufferer can make breather cheek valve 127 open air inlet 125, and makes one-way exhaust valve 128 deadend steam vents 126.

At this moment, outside air then can enter air inlet 125, supplying the inspiration capacity of sufferer, and most medicine mist 600 can be directed at mixed gas outlet 112 simultaneously whereby to allow sufferer draw, and can not be drawn onto too much air, can increase medicament 400 absorption efficiencies and reduce the treatment time-histories.

After inhaling medicine, sufferer will inevitably exhale again so that the waste gas in the pulmonary is discharged, the expiration power of sufferer can make one-way exhaust valve 128 open steam vent 126, the waste gas that sufferer is breathed out drains into the external world via mixed gas outlet 112 and exhaust passage 124, and filtered by filter material 130 simultaneously, diffuse to the external world and influence hygienic conditions to avoid virus or antibacterial in the waste gas.

This moment is because the inspiratory force disappearance, make breather cheek valve 127 closed grate hole 126 again, make medicine mist 600 can not run off, reduce unnecessary waste, and because of the channel cross-sectional area of mixed-gas channel 129 much smaller than the exhaust passage 124 channel cross-sectional area, make waste gas be difficult to enter in the chamber 111 and the overwhelming majority 124 drains into the external world from the exhaust passage.

When sufferer is desired to stop to draw medicine mist 600, only need discharge and pull arm 321, the elastic arm 323 of then deflection deformation breaks away from sealing with valve 322 and relief hole 312 whereby with its elastic restoring force reinstatement and elasticity pushing and pressing compacting bar 324, makes relief hole 312 open-minded.

When relief hole 312 is opened, because the aperture size of relief hole 312 is much larger than the aperture size of Compressed Gas inlet 212, then Compressed Gas 500 can flow toward hindering little position, therefore cause Compressed Gas 500 to flow out to the external world and can not enter Compressed Gas inlet 212, stop to produce medicine mist 600 in this way from relief hole 312 dissipations.

The utlity model has suitable ease of use, sufferer only need continue to pull pressing mechanism 300 can draw medicine mist 600, discharge pressing mechanism 300 and just do not have 600 generations of medicine mist, so can reduce medicament 400,600 wastes of medicine mist, with these a large amount of medication efficient, medical effects of promoting, again in therapeutic process, sufferer is blown and but medicine mist 600 can not discharged from chamber 111, can effectively preserve medicament 400, medicine mist 600, in addition, the waste gas that sufferer blows out can be filtered by filter material 130, avoids virus or antibacterial in the waste gas to diffuse to the external world, and can safeguard the environment of health.

Certainly; this utility model also can have other various embodiments; under the situation that does not deviate from this utility model spirit and essence thereof; those of ordinary skill in the art work as can make various corresponding changes and distortion according to this utility model, but these corresponding changes and distortion all should belong to the protection domain of the appended claim of this utility model.
