Description
Technical field
The present invention relates to atomization plant technical field, particularly a kind of gas compression formula nebulizer of low noise goes out gas transfer device.
Background technology
Nebulizer passes through compressed air, medicinal liquid is formed air blast to be ejected into and to haze on baffle plate, liquid water molecules structure broken up and produces the equipment of water smoke, there is the function of medical treatment, humidification and beauty treatment, be applicable to the treatment of the upper respiratory tract infection diseases such as flu, allergic rhinitis, tracheitis.At present, gas compression formula nebulizer obtains extensive use in clinical medicine, but all there is a general problem in existing gas compression formula nebulizer in Clinical practice, namely over the course for the treatment of, the noise that gas compression formula nebulizer produces is larger, in order to give hospital and patient's quiet Curing circumstance, reduce the noise produced when gas compression formula nebulizer runs as possible is the direction that everybody pursues always, run noise and become one of important performance indexes of gas compression formula nebulizer, people pay a lot of effort for this reason.
Know by testing us, the air of certain pressure and flow velocity is needed to have in order to obtain atomization, nebulizer produces noise because of compressed air, the best part producing noise is having air intake installation and the air-out apparatus of annexation with machine compression chamber, because air intake installation is equipped with filter, and air velocity and pressure are not had to the requirement of definite value, air velocity and pressure can do very low, so easily realize noise control.And in gas outlet, the air (, generally at 60-120kP, flow is generally at 5-7L/min for pressure) with certain pressure and flow velocity required for atomization should be obtained, effectively realize again just becoming a scabrous problem to the control of noise.
Summary of the invention
The object of the invention is to the shortcoming overcoming prior art, provide a kind of effectively reduce output noise, simultaneously make the air-flow of output more steadily, the gas compression formula nebulizer of low noise goes out gas transfer device.
Object of the present invention is achieved through the following technical solutions: a kind of gas compression formula nebulizer of low noise goes out gas transfer device, it comprises body, body interior is provided with closed decompression and expansion chamber, sidewall near body one end is provided with and is communicated with decompression and expansion chamber and outside air inlet pipe, the inside of air inlet pipe is provided with air inlet through hole, the end face of the other end of body is provided with and is communicated with decompression and expansion chamber and outside escape pipe, the inside of escape pipe is provided with out vent hole, and the outlet side of escape pipe is provided with the orifice plate that capping goes out vent hole, orifice plate is evenly equipped with venthole.
Air inlet pipe is connected with the gas circuit of pneumatic supply by connecting trachea, and escape pipe is connected with the gas circuit of atomizing cup assembly by connecting trachea.
The present invention has the following advantages: the escape pipe by air inlet pipe, decompression and expansion chamber and band abacus capping outlet side of the present invention form one closed there is two-stage noise reduction go out gas transfer device, by two-stage noise reduction, under the prerequisite of pressure and flow velocity is not lost in guarantee, realize effective control gas compression formula nebulizer being exported to gas noise, make the air-flow of output more steady simultaneously, the user demand of patient can be met better, do not affect instrument original function simultaneously, there is the features such as structure is simple, safe and reliable.

Detailed description of the invention
Below in conjunction with accompanying drawing, the present invention will be further described, and protection scope of the present invention is not limited to the following stated:
As shown in Figure 1, a kind of gas compression formula nebulizer of low noise goes out gas transfer device, it comprises body 1, as Fig. 1, Fig. 2, shown in Fig. 4, body 1 inside is provided with closed decompression and expansion chamber 2, sidewall near body 1 one end is provided with and is communicated with decompression and expansion chamber 2 and outside air inlet pipe 3, the inside of air inlet pipe 3 is provided with air inlet through hole, the end face of the other end of body 1 is provided with and is communicated with decompression and expansion chamber 2 and outside escape pipe 4, the inside of escape pipe 4 is provided with out vent hole, and the outlet side of escape pipe 4 is provided with the orifice plate 5 that capping goes out vent hole, as Fig. 1, shown in Fig. 3, orifice plate 5 is evenly equipped with several ventholes.
As shown in Figure 5, air inlet pipe 3 is connected with the gas circuit of pneumatic supply 7 by connecting trachea 6, and escape pipe 4 is connected with the gas circuit of atomizing cup assembly 8 by connecting trachea 6.
In the present embodiment, body 1 is cylinder, and air inlet pipe 3 is arranged on the sidewall of cylindrical member at one end, and escape pipe 4 is arranged on the end face of the cylindrical other end.
Work process of the present invention is as follows: the high-speed compressed air that pneumatic supply 7 produces enters out the decompression and expansion chamber 2 of gas transfer device by connection trachea 6 and air inlet pipe 3, utilize sudden change and the expansion of cavity, form first order decompression and expansion noise reduction, and make air-flow more steady, the air pressure fluctuation that effective reduction produces because of compressor compresses air, the orifice plate 5 that the end of escape pipe 4 is arranged adopts loose structure, utilize the principle that small hole injection is eliminated the noise, at maintenance flow, under the condition that pressure is constant, with multiple keyhole formation second level noise reduction, reduce A sound level, eliminate the impact noise spraying and produce, air after treatment outputs to atomizing cup assembly 8 by porous gas outlet, thus realize effective control gas compression formula nebulizer being exported to gas noise, make output gas flow more steady.
