Currently, existing small-sized sputum aspirator suction sputum is poor due to sealing, enough negative pressure cannot be formed in liquid storage bottle, are caused Suction sputum pressure is inadequate.Although large-scale sputum aspirator suction sputum pressure is enough, volume is larger, and general weight is greater than 10kg, carries, Carrying is more difficult, and general price is higher, is not suitable for general family and uses.
Utility model content
The task of the utility model is to propose a kind of sputum aspirator, which belongs to small-sized sputum aspirator, and structure is simple, is changed Sputum aspirator sealing performance has been apt to it, and then has increased the suction pressure of suction sputum, has solved existing small-sized sputum aspirator pressure suction sputum pressure Inadequate problem.
To achieve the goals above, a kind of sputum aspirator provided by the utility model, specific technical solution are as follows:
A kind of sputum aspirator, including liquid storage bottle 1, bottle stopper 2, sputum guiding tube 3, negative tube 4, the 1 oral area inner surface of liquid storage bottle are set Set secondary sealing mating surface 1-1 and primary seal slot 1-2, the bottle stopper 2 be provided with secondary sealing area 2-2, primary seal dome ring 2-3, Sputum guiding tube mounting hole 2-5, negative tube mounting hole 2-6, sputum guiding tube mounting hole sealing locating slot 2-8, the sealing of negative tube mounting hole are fixed Position slot 2-7,3 outer surface of sputum guiding tube are provided with sealing convex annulus 3-1, and 4 outer surface of negative tube is provided with sealing Convex annulus 4-1, the liquid storage bottle 1 pass through secondary sealing mating surface 1-1 and primary seal slot 1-2 and 2 secondary sealing area of bottle stopper respectively 2-2 and primary seal dome ring 2-3 forms sealing cooperation, and the bottle stopper 2 is close by sputum guiding tube mounting hole 2-5 and sputum guiding tube mounting hole It seals locating slot 2-8 and 3 outer surface of sputum guiding tube and sealing convex annulus 3-1 sealing cooperates, the bottle stopper 2 is installed by negative tube Hole 2-6 and 4 outer surface of negative tube and sealing cooperation sealing convex annulus 4-1 sealing cooperate.
Further technical solution, in order to reach better seal effect, the 1 secondary sealing mating surface 1-1 of liquid storage bottle with 2 secondary sealing area 2-2 of bottle stopper is circular conical surface.
Further technical solution enters liquid storage bottle 1 in order to facilitate bottle stopper 2, and the bottle stopper 2 is additionally provided with guiding installation and falls Edged surface 2-1.
Further technical solution, holds sputum aspirator for convenience, and 1 oral area of liquid storage bottle is additionally provided with step cutting pattern 1- 3。
Further technical solution, bottle stopper 2 excessively fills in liquid storage bottle 1 in order to prevent, while more convenient from liquid storage bottle 1 Middle taking-up bottle stopper 2, the bottle stopper 2 are additionally provided with positioning round table 2-4.
Compared with prior art, the utility model has the beneficial effects that
1, the sputum aspirator structure of the utility model is simple, and using multi-sealing structure, it is close to solve general small-sized sputum aspirator Envelope effect is poor, and the problem of suction sputum insufficient pressure;
2, the sputum aspirator of the utility model is optimized in structure, and bottle stopper more convenient can enter liquid storage bottle and not It can slide into inside liquid storage bottle, it is also more convenient to extract bottle stopper;
3, sputum guiding tube mounting hole and negative tube mounting hole are provided with sealing positioning in the novel sputum aspirator bottle stopper of this practicability Slot, by with sputum guiding tube and negative tube setting sealing convex annulus mating reaction, both realized to the multiple of sputum aspirator Sealing, while sputum guiding tube and negative tube are positioned, it effectively prevent sputum guiding tube and negative tube to slide in bottle stopper.
