Section section cylindrical cavity joint forms first step, second segment cylindrical cavity and third section section cylindrical cavity joint shape
At second step；First fluid connector 8A is tightly fixed in the cavity of first passage first segment by fastening frame 9A, and
The right side of first fluid connector and the right end of first passage first segment cavity form the cavity with certain distance.First valve
Core is T-shape, i.e., is made of different two sections of diameter, and the diameter of the first segment 11A of the first spool is greater than the second of first passage
The internal diameter of section section cylindrical cavity, the diameter of the second segment 13B of the first spool are equal to the second segment section cylindrical empty of first passage
The internal diameter of chamber.First spool is provided with one section of cavity 14A, the left end of cavity and the first segment cylindrical empty of first passage along axle center
Chamber is in fluid communication, and opening 15B is provided on the side wall of the first spool, and the cavity 14A in the opening and the first spool is in fluid communication.
Spring 10A, the left end of the first spool are provided between the left end of first spool and the right part section inner cavity of first fluid connector 8A
It is embedded in the right end of spring 10A, the left end of spring 10A is against on the ladder inside first fluid connector.The right side of first spool
End 16A stretches out the certain length of valve body 20 and can be in contact with the flange 17A of change-over switch 60.The first segment of first spool and
Two sections of intersections are additionally provided with pressure spring bulge loop 12A, for being stuck in the first spool closely, actively in first passage.
Third channel is identical as the structure of first passage, and the second spool is also identical as the structure of the first spool, here no longer
It repeats.
In use, the insertion of connector 42 intubation 35 by the insertion of connector 46 intubation 66, is made to switch the connecting flange on valve body
47 are fixedly connected with the connecting flange 37 on outer cylinder 31, are provided with sealing ring in order to seal, between them.By the first of switch valve
Spool is pressed to first position and rotation, is connected to 64 via through holes 40 of connector, connector 42, intubation 5 with cavity 33, is injected certain pressure intensity
Clean compressed air or compressed oxygen, then the first spool of switch valve is drawn to the second position.By the of switch valve
Two spools are pressed to first position and rotation, are connected to 65 via through holes 44 of connector, connector 46, water pipe 36 with cavity 34, injection is drunk
Water then draws the second spool to the second position, in this way, compressed air or oxygen are sealing into inner cylinder 32, drinking water is enclosed
Into cavity 34, and compressed air is surrounded by water, in this way, water can cool down the air around compressed air, makes compressed air
It is relatively stable.Supply arrangement, fixed device, control device, mask and two hose packages for being filled with water and compressed air exist
In one packaging bag or box, it is distributed to user, use when meeting an urgent need with standby user.User is in use, mask is worn on the head, supply
Equipment is fixed on the securing means, and with fixed device is worn, and one end of the first hose 23 is made to be fixed to the outside of oronasal mask
On air induction hose connector, the other end is fixed to the connector of the second channel of control device, and control device connector 8A passes through hose
The air connector being connected on supply arrangement；One end of the second hose 26 is set to be fixed to the water supply hose connector of the outside of oronasal mask
On, the other end is fixed to the connector of the fourth lane of control device, and control device connector 8B is connected to supply by hose and sets
Standby upper water supply joint.Then, it shifts the first spool of switch valve onto first position and rotates, keep its flow moderate, in this way, dry
Net air can be discharged into oronasal mask under control of the control means, in oronasal mask on be provided with gas vent, due to mouth and nose
Air in cover is positive pressure, so the carbon dioxide that part cleaned air is discharged together with user is discharged to the external world by gas vent.
When user needs drinking water, shifts the second spool of switch valve onto first position and rotate, make for water/gas connector and cavity 34
Connection, user is by sucking the drinking water in cavity 34 for head.
The present invention is since the container for accommodating air to be arranged within the container for accommodating water, in this way, not only alloing water right
Compressed air carries out a period of time cooling, avoids making compressed air expansion that secondary wound occur since temperature is excessively high in scene of fire
It is harmful, while in emergency, family can be used and drink clean water, clean air is arrived in breathing, so that user's holding be made to regain consciousness
Brains, and can accurately judge various situations, and then can correctly be detached from scene of fire.
Have been described in detail above with reference to the accompanying drawings the present invention, but what specification was only for interpreting the claims.But this
Protection scope of the present invention is not limited to specification.Skill of the anyone skilled in the art in present disclosure
Within the scope of art, the variation or replacement that can be readily occurred in be should be covered by the protection scope of the present invention.Therefore, of the invention
Protection scope should be subject to the scope of protection of the claims.
