Description
Technical field
The invention belongs to medical instruments fields, and in particular to a kind of vaporizer.
Background technology
Atomization inspiration treatment breathing problem is a kind of important, effective method, is a kind of accurate therapeutic treatment disease
Method, using nebulizer by liquid by sucking by the way of enter respiratory tract and lung, reach noninvasive, local treatment,
Purpose that is painless, rapid, effectively treating, can also utmostly avoid systemic complications.
It is divided according to operation principle, main two kinds of the atomizer clinically used at present：One kind is ultrasonic atomizer, a kind of
It is jet flow type atomizer.Jet flow type atomizer is according to venturi ejector principle, is formed using compressed air by tiny nozzle
High-speed flow, the negative pressure of generation drive liquid to be ejected into obstruction together, splash around under high-speed impact so that drop
Become droplet particle to spray from air outlet pipe.
Chinese invention patent application such as application No. is 201510785890.6 discloses a kind of vaporizer, this is medical
Atomizer includes atomizing cup, atomization core and atomization lid；Wherein, the bottom of atomizing cup is equipped with air inlet pipe, and one end of air inlet pipe is equipped with

Specific embodiment
Technical scheme of the present invention is described in further details with reference to the accompanying drawings and detailed description.
Embodiment 1
As depicted in figs. 1 and 2, a kind of vaporizer of the present embodiment including atomization tank 1, atomization core 2 and is atomized lid 3,
In, the open top of atomization tank 1 has internal thread, and the top outer wall of atomization core 2 is equipped with external screw thread, passes through mutual cooperation
Atomization core 2 is fixed on atomization tank 1 by internal thread and external screw thread.The top open part of atomization core 2 then passes through seal-locking mechanism
It is fixedly connected with atomization lid 3.
As shown in figure 4, the seal-locking mechanism includes being arranged on the buckle 31 at 3 edge of atomization lid and is arranged on atomization core 2
Snap seats 21 on outer wall.
As seen from Figure 1, the bottom of atomization tank 1 is equipped with nozzle 11, and the top of nozzle 11 is equipped with spray orifice 12, the bottom of atomization tank 1
Portion is equipped with the recessed reservoir compartment 13 for being set around 11 periphery of nozzle, and 11 outer wall of nozzle is wholely set with 13 side wall of reservoir compartment.
Delivery outlet 14 is offered on the side wall of atomization tank 1, efferent duct 15, efferent duct 15 and breathing are installed at delivery outlet 14
Mask 16 is connected；Also, efferent duct 15 has in the extended segment 17 of 1 inside of atomization tank, and the outer wall formation of extended segment 17 is used for
Prevent the liquid in reservoir compartment 13 from entering the baffle of delivery outlet 14.When atomization tank 1 tilts, the medicine come is flowed through from reservoir compartment 13
Liquid is only in the flowing of the periphery of extended segment 17, will not enter delivery outlet 14, and liquid is from output when avoiding the atomization tank 1 from tilting or keep flat
Mouth 14 enters patient's mouth and nose, causes medication accident.
Also, in one end towards 1 inside of atomization tank, the opening of extended segment 17 carries flanging 18.18 energy of flanging
Enough further enhance barrier effect of the extended segment 17 to liquid.In the present embodiment, flanging 18 is parallel with 1 inner wall of atomization tank to be set
It puts；Further, it is also possible to flanging 1 is arranged to bell mouth shape, bell-mouthed openings of sizes is from the outer edge of flanging 18 to prolonging
The opening for stretching section 18 tapers into.
As shown in Figure 2, with reference to Fig. 1 as it can be seen that the bottom of atomization core 2 is equipped with liquid injection port 22, being carried at the liquid injection port 22 can cover
The liquid injection pipe 23 being connected on outside nozzle 11.Above spray orifice 12, pressure release orifice 24, this reality are offered on the side wall of liquid injection pipe 23
It applies example and has circumferentially been uniformly arranged four pressure release orifices 24 around liquid injection pipe 23.
After opening up pressure release orifice 24, in no compressed air into fashionable, if the liquid disposably injected is excessive, liquid
Not only can reservoir compartment be injected by liquid injection pipe 23, can also reservoir compartment, liquid injection rate be injected by pressure release orifice 24
Soon, injection process is smooth, and liquid will not be put aside at 2 top of atomization core.When compressed air is into fashionable, if the liquid in liquid injection pipe 23
Higher than the residing height of spray orifice 12, then compressed air also can escape (as shown in Figure 3) at pressure release orifice 24, will not be by liquid in face
Jack-up causes liquid to flow backwards.
In the present embodiment, the openings of sizes of pressure release orifice 24 is suitable with the openings of sizes of liquid injection port 22.If pressure discharges
The opening of mouth 24 is too small, then the efficiency for discharging liquid or compressed air is too low, it is also possible to liquid is formed at pressure release orifice 24
Film hinders liquid outflow or compressed air effusion.
