Fixing piece 31 for being fixedly mounted in third mounting base 17.
By setting sputum aspirator 18 to detachable structure, since the whole apparatus volume of sputum aspirator 18 is larger, do not needing
When can dismantle, facilitate endoscopic technic, at the same avoid no doctor help under since its preponderance draws downwards mask,
By being provided with adjustable spool 20 in third mounting base 17, spool 20 is replied in second spring part 29 and the first spring part 22
It keeps mutually contradicting with first boss 24 under power, prevents the air on the inside of mask from being flowed out by third mounting base 17, when in use,
The tube wall of sputum aspirator 18, which is installed in third mounting base 17, pushes sliding block 26 to be moved far from 24 side of first boss, while driving valve
Gap is formed between core 20 and first boss 24, can pass through the through-hole of shell 19 in 18 negative pressure leaching sputum of sputum aspirator
23 are attracted out, are fixed by fixing piece 31 when sputum aspirator 18 is mounted on third 17 outer wall of mounting base, fixing piece 31 can
Think dead ring, outer spiral shell can also be set in 17 outer wall of third mounting base by the way that internal thread is arranged on the inside of 18 tube wall of sputum aspirator
Line, sputum aspirator 18 and third mounting base 17 are threadedly coupled, and detachable structure disclosed above makes sputum aspirator 18 be installed to the
When in three mounting bases 17, the through-hole 23 of third mounting base 17 is kept unimpeded, when sputum aspirator 18 and third mounting base 17 are dismantled, the
The sealing of through-hole 23 of three mounting bases 17 is closed.
As a kind of improved specific implementation mode, it is inlaid with and is used for and shell on the contact surface of spool 20 and 19 inner wall of shell
First O-ring 32 of 19 inner wall of body contact, spool 20 and 19 inner wall of shell are close in contact by the first O-ring 32 so that logical
Hole 23 keeps closed.
As a kind of improved specific implementation mode, the outer wall of shell 19 towards 1 lateral surface of mask body, which is provided with, to be used for
The second O-ring 33 being interference fitted with sputum aspirator 18 plays sealing function when sputum aspirator 18 and the installation of shell 19 connect, keeps
Third mounting base 17 is in negative pressure state when sputum aspirator 18 works.
As a kind of improved specific implementation mode, spatula component 16 includes spatula 34 and operating lever 35, the pressure tongue
Plate 34 is fixedly mounted on the second mounting base 15 towards 1 medial surface side of mask body, and the second mounting base 15 is towards outside mask body 1
Side side is provided with blind hole 36, operating lever 35 and 36 grafting of blind hole.
It sets spatula component 16 to separate structure, when in use, operating lever 35 will be held and control the second mounting base 15
Direction so that control spatula 34, keep its simple in structure, while disinfection easy to disassemble.
As a kind of improved specific implementation mode, operating space includes endoscopic technic area 37, spatula operating space 38 and inhales
Sealing shroud 11 is respectively set in phlegm device operating space 39, endoscopic technic area 37, spatula operating space 38 and sputum aspirator operating space 39, sealing
Set 11 is provided with telescopic bellows 40, which is tightly connected with opening 10, and the material of bellows 40 is rubber.
By the way that operating space subregion is arranged so that it will not influence each other when controlling scope, spatula 34 and sputum aspirator 18,
Its sealing shroud 11 is relatively independent so that when controlling the direction of the first mounting base 12, the second mounting base 15 and third mounting base 17
It is more flexible, additionally by telescopic bellows 40 is arranged so that sealing shroud 11 has certain stretching, extension empty in all directions
Between, it can store when not in use, keep its overall volume smaller so that can be more comfortable when mask is worn.
As a kind of improved specific implementation mode, gas outlet 3 is arranged in the lower end of mask body 1, and receiving flask 5 includes upper
Layer and lower layer, 5 upper layer of receiving flask offer the venthole 42 of the air admission hole 41 and connection negative pressure device 7 of connection gas outlet 3, filtering
For 6 setting of layer in 5 lower layer of receiving flask, filter layer 6 includes the active carbon filtration layer 43 set gradually and the filtering for being adsorbed with thimerosal
Cotton layer 44, the air admission hole 41 of receiving flask 5 is provided with the tracheae 45 for stretching into filter cotton layer 44.
By the way that active carbon filtration layer 43 is arranged in receiving flask 5 and is adsorbed with the filter cotton layer 44 of thimerosal, patient's exhalation
Gas attracted by negative pressure device 7, gas first imports filter cotton by tracheae 45, does to the bacterial virus carried in gas and tentatively disappears
Poison, then pass through the further filtering out harmful matter of activated carbon layer.
The above is only the preferred embodiment of the present invention, protection scope of the present invention is not limited merely to above-described embodiment,
All technical solutions belonged under thinking of the present invention all belong to the scope of protection of the present invention.It should be pointed out that for the art
