Abstract
The invention discloses a low-noise output gas conversion device for a gas compressed atomizer. The low-noise output gas conversion device comprises a body (1). A closed decompression and expansion cavity (2) is formed in the body (1); the side wall close to one end of the body (1) is provided with an inlet pipe (3) communicating the decompression and expansion cavity (2) and the outside; the end face of the other end of the body (1) is provided with an outlet pipe (4) communicating the decompression and expansion cavity (2) and the outside; the outlet end of the outlet pipe (4) is provided with a pore plate (5) for covering an outlet through hole; the pore plate (5) is uniformly provided with outlet holes. The low-noise output gas conversion device has the advantages that the inlet pipe, the decompression and expansion cavity and the outlet pipe provided with the pore plate for covering the outlet end form a closed two-stage noise reduction output gas conversion device; by two-stage noise reduction, on the premise of not losing pressure and flow rate, the noise of the output gas of the gas compressed atomizer is effectively controlled and the output airflow is more stable.
Description
Technical field
The gas compression formula nebulizer that the present invention relates to atomization plant technical field, particularly a kind of low noise goes out gas transfer device.
Background technology
Nebulizer is to pass through compressed air, medicinal liquid is formed to air blast to be ejected into and to haze on baffle plate, liquid water molecules structure broken up and produce the equipment of water smoke, thering is the function of medical treatment, humidification and beauty treatment, being applicable to the treatment of the upper respiratory tract infection diseases such as flu, allergic rhinitis, tracheitis.At present, gas compression formula nebulizer has obtained extensive use in clinical medicine, yet all there is a general problem in existing gas compression formula nebulizer in clinical use, in therapeutic process, the noise that gas compression formula nebulizer produces is larger, in order to give hospital and patient one, quietly treat environment, the noise producing while reducing as possible the operation of gas compression formula nebulizer is the direction that everybody pursues always, operation noise has become one of important performance indexes of gas compression formula nebulizer, and people pay a lot of effort for this reason.
By testing us, know, the air need in order to obtain atomization with certain pressure and flow velocity, nebulizer produces noise because of compressed air, the best part that produces 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 be there is no to the requirement of definite value, air velocity and pressure can be done very lowly, so easily realize noise control.And in gas outlet, should obtain the needed air (pressure is generally at 60-120kP, and flow is generally at 5-7L/min) with certain pressure and flow velocity of atomization, effectively realize again the control of noise is just become to a scabrous problem.
Summary of the invention
The object of the invention is to overcome the shortcoming of prior art, the air-flow that provides a kind of and effectively reduce output noise, makes simultaneously 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 the decompression and expansion chamber of sealing, on the sidewall near body one end, be provided with and be communicated with decompression and expansion chamber and outside air inlet pipe, the inside of air inlet pipe is provided with air inlet through hole, on the end face of the other end of body, be provided with and be 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, on orifice plate, be 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: of the present invention by air inlet pipe, decompression and expansion chamber with form the gas transfer device that with two-stage noise reduction of a sealing with the escape pipe of abacus capping outlet side, can be by two-stage noise reduction, in assurance, do not lose under the prerequisite of pressure and flow velocity, the effective control of realization to gas compression formula nebulizer output gas noise, make the air-flow of output more steady simultaneously, can meet better patient's user demand, do not affect instrument original function, there is the features such as simple in structure, safe and reliable simultaneously.

The specific embodiment
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 the decompression and expansion chamber 2 of sealing, on the sidewall near body 1 one end, be provided with and be 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, on the end face of the other end of body 1, be provided with and be 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, on orifice plate 5, be 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 cylinder 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 connecting 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, effectively reduce the air pressure fluctuation producing because of compressor compresses air, the orifice plate 5 that the end of escape pipe 4 arranges adopts loose structure, the principle of utilizing small hole injection to eliminate the noise, keeping flow, under the constant condition of pressure, with a plurality of apertures, form second level noise reduction, reduce A sound level, eliminate and spray the impact noise producing, air after treatment outputs to atomizing cup assembly 8 by porous gas outlet, thereby realize the effective control to gas compression formula nebulizer output gas noise, make output gas flow more steady.
