Background technology
Along with in recent years, air-polluting increases the weight of, environment worsens, ventilation of windowing can not solve room air pollution, along with increasing of requiring indoor environment, with oxygen, crowd sharply increases, especially the increasing substantially of oxygen crowd in old age, also more and more higher to the requirement of the quality and performance of oxygen enrichment terminal device, but the air of the high noisy of low-purity oxygen plant and indoor pollution has had a strong impact on the sleep quality of people, the high-concentration oxygen of oxygen enrichment terminal device outlet simultaneously has also brought certain potential safety hazard.
The high noisy of low-purity oxygen plant terminal and the air of indoor pollution in the market, makes people's exigence a kind of not only quiet but also can the multifunctional terminal device of improving water flood quality.
Utility model content
Goal of the invention of the present utility model is: for current oxygen enrichment terminal high noisy and function singleness, provides a kind of low noise and the multifunctional safe oxygen enrichment terminal device improving air quality.
The technical solution adopted in the utility model is such:
A kind of empty oxygen mixed diluting terminal installation with noise reduction and PM2.5 filtering function, comprise master board, oxygen silencers channel, oxygen feeder, oxygen supply switch, muffler, air intake pipe and empty oxygen mixing chamber, the air intake of described air intake pipe is provided with PM2.5 filter cotton, the air outlet slit of air intake pipe is communicated with empty oxygen mixing chamber, is also provided with fan and oxygen concentration probe in described air intake pipe; Described oxygen feeder one end is communicated with apparatus of oxygen supply, the oxygen feeder other end connects oxygen supply switch by pipeline, oxygen supply switch is by pipeline joint noise reduction device, muffler connects oxygen silencers channel by pipeline, the oxygen outlet of described oxygen silencers channel is communicated with empty oxygen mixing chamber, described empty oxygen mixing chamber is provided with gas vent, and described master board controls the normal operation of whole device.
As preferably, described PM2.5 filter cotton adopts HEPA high efficiency filter cotton.
As preferably, described HEPA high efficiency filter cotton is detachable filter cotton.
As preferably, the oxygen concentration in described oxygen concentration probe detection air, master board automatically starts oxygen supply switch in the oxygen ranges of default.
As preferably, the rotating speed of described fan is regulated by master board, to control the air force that air enters air intake pipe.
As preferably, described oxygen supply switch is magnetic valve.
As preferably, described oxygen silencers channel and muffler adopt plastics or metallic article.
In sum, owing to have employed technique scheme, the beneficial effects of the utility model are:
1, the utility model structure is simple, reasonable in design, the oxygen content in air is gone out by oxygen concentration probe detection, then oxygen is entered sky oxygen mixing chamber mix with the pure air filtered through PM2.5 through muffler, oxygen silencers channel, air quantity in air intake pipe regulates by fan, thus can obtain the pure air of oxygen enrichment under low noise state.
2, the utility model both can reduce the noise of terminal oxygen equipment effectively, can also purify air, and make the air after oxygen and cleaning naturally overflow after mixed diluting in empty oxygen mixing chamber, effective dilution oxygen concentration, makes people safer with oxygen simultaneously.

Detailed description of the invention
By reference to the accompanying drawings the utility model is described in further detail now.These accompanying drawings are the schematic diagram of simplification, only basic structure of the present utility model are described in a schematic way, and therefore it only shows the formation relevant with the utility model.
As depicted in figs. 1 and 2, a kind of empty oxygen mixed diluting terminal installation with noise reduction and PM2.5 filtering function, comprise master board 1, oxygen silencers channel 2, oxygen feeder 3, oxygen supply switch 4, muffler 5, air intake pipe 7 and empty oxygen mixing chamber 9, the air intake of described air intake pipe 7 is provided with PM2.5 filter cotton 6, wherein, PM2.5 filter cotton 6 adopts dismountable HEPA high efficiency filter cotton, the air outlet slit of air intake pipe 7 is communicated with empty oxygen mixing chamber 9, fan 8 and oxygen concentration probe 10 is also provided with in described air intake pipe 7, described oxygen concentration is popped one's head in the oxygen concentration in 10 detecting airs, master board 1 automatically starts oxygen supply switch 10 in the oxygen ranges of default, the rotating speed of described fan 8 is regulated by master board 1, to control the air force that air enters air intake pipe 7.
Described oxygen feeder 3 one end is communicated with apparatus of oxygen supply, oxygen feeder 3 other end connects oxygen supply switch 4 by pipeline, wherein, oxygen supply switch 4 adopts magnetic valve, oxygen supply switch 4 is by pipeline joint noise reduction device 5, and muffler 5 connects oxygen silencers channel 2 by pipeline, and the oxygen outlet of described oxygen silencers channel 2 is communicated with empty oxygen mixing chamber 9, described empty oxygen mixing chamber 9 is provided with gas vent, and described oxygen silencers channel 2 and muffler 5 adopt plastics or metallic article.
Described master board 1 controls the normal operation of whole device, and namely master board 1 and oxygen supply switch 4, muffler 5, fan 8, empty oxygen mixing chamber, oxygen concentration are popped one's head in and 10 to be electrically connected.
The utility model is when reality uses, master board starts this device, PM2.5 filter cotton 6 filtered air is passed in air intake pipe 7, oxygen concentration is popped one's head in the oxygen concentration in 10 Real-Time Monitoring air, and the oxygen concentration recorded and setting value are compared, if the oxygen concentration in air is lower than setting value, oxygen oxygen supply switch 4 is opened in master board 1 automatically, after air and oxygen being arrived fully mix in empty oxygen mixing chamber 9, naturally overflow from the gas vent of empty oxygen mixing chamber 9; Otherwise, then do not need to open oxygen oxygen supply switch 4.
With above-mentioned according to desirable embodiment of the present utility model for enlightenment, by above-mentioned description, relevant staff in the scope not departing from this utility model technological thought, can carry out various change and amendment completely.The technical scope of this utility model is not limited to the content on description, must determine its technical scope according to right.
