Fig. 1 is the separate structure schematic diagram of a kind of air purifier of the present invention;
Fig. 2 is the diaphragll type air cyclone separator arrangement schematic diagram of air purifier of the present invention.
Detailed description of the invention
Below in conjunction with the accompanying drawing in the embodiment of the present invention, be clearly and completely described the technical scheme in the embodiment of the present invention, obviously, described embodiment is only the present invention's part embodiment, instead of whole embodiments.Based on the embodiment in the present invention, those of ordinary skill in the art, not making the every other embodiment obtained under creative work prerequisite, belong to the scope of protection of the invention.
As shown in Figure 1, air purifier of the present invention, comprise: main air casing 3, turbofan 4, electronic turbocharger 5, diaphragll type air separator 6 and air humidifier 8, also comprise central processing unit and electronics gas-sensing probe, central processing unit presets indoor air temperature index, humidity index, oxygen index value and nitrogen index.
Electronics gas-sensing probe obtains temperature information and the humidity information of room air, again temperature information and humidity information are passed to CPU, CPU compares with humidity index with the humidity index preset with humidity information to the temperature information received, according to comparative result, work is sent and the instruction that quits work to air humidifier, preferably, described air humidifier is ultrasonic water atomization type device.
CPU of the present invention compares with humidity index with preset air humidity index to the temperature and humidity information received, and adopts existing comparison program, does not relate to the improvement to existing program.
The program that CPU controls air humidifier according to comparative result, is existing control program, is the known technology of this area, does not relate to the improvement to existing control program.
In electronics gas-sensing probe transfer chamber, content of oxygen in air information and nitrogen content information are to CPU, oxygen content information and nitrogen content information contrast with the oxygen index value preset and nitrogen index by CPU, when comparative result is variant, namely turbocharger is started, secondary pressurized is carried out to the wind that turbofan is brought, for air separator provides qualified air stream.
Diaphragll type air separator is after the air stream receiving turbocharger conveying, air-flow is when the oxygen nitrogen diffusion barrier by separator, because oxygen is different with the electronic polarity of nitrogen, by oxygen nitrogen diffusion barrier polarization separation respectively, oxygen is by the gas outlet, top of separator, flow to indoor, nitrogen is then by nitrogen gas delivery-line 7 that the lower exit port of separator connects, nitrogen is sent outdoor, when oxygen in room air and nitrogen content information reach CPU preset index time, CPU then sends the instruction quitting work He do not start to electronic turbocharger, electronic turbocharger will be in and not start and halted state.Below in conjunction with accompanying drawing, diaphragll type air separator of the present invention is described in detail.
Nitrogen in the middle of air and oxygen, because its density is almost identical, so remain the mixed state of balance, for a long time, air separation takes compression, drying of drying, cryogenic liquefaction usually, different with the liquefaction point of liquid oxygen according to liquid nitrogen, thus carry out the mode that is separated, carry out oxygen and nitrogen processed, this mode can obtain the oxygen of high purity more than 99%, belongs to vocational work and medical use oxygen.The present invention is in the process of purification of air, carry out oxygenation operation, do not need highly purified oxygen, only need the air of oxygen content 25-40%, carry out convection current with the air in room and mix, to reaching to the object of oxygenation operation in room, therefore, the present invention takes composite membrane air-separating technology, is separated the air after turbocharging, can obtain satisfied oxygenation effect.
As shown in Figure 2, molecular diameter size according to the oxygen in the middle of air and nitrogen has other feature, diaphragll type air separator of the present invention selects circulation aperture be less than nitrogen and be greater than the composite filtering film 64 of oxygen, molecular sieve as air separation uses, when blowing to composite filtering film 64 through the air stream of turbocharger 5, oxygen molecule is less than the opening diameter of composite filtering film 64 due to diameter, and preferentially pass through composite filtering film, enter oxygen collecting chamber 65, flow to indoor by indoor oxygen discharge conection 66 again, play room air oxygenation effect; Nitrogen molecular is greater than the opening diameter of composite filtering film 64 due to molecular diameter, is intercepted at nitrogen collecting chamber 62, be transported to outdoor, be discharged in outside atmosphere by nitrogen discharge conection by composite filtering film 64.Adopt the oxygen-enriched air that diaphragll type air separator obtains, oxygen content is generally 25-40%, by the operation of a period of time, room air can be made to improve oxygen content, to the physical and mental health of human body, provide useful effect.
Preferably, as shown in Figure 1, the front panel 1 of air purifier of the present invention also comprises after electronic data display screen 2, CPU obtains indoor air temperature information, humidity information, oxygen content information and nitrogen content information, and the electronic data display screen sending clarifier to carries out data display.
Preferably, air purifier of the present invention also comprises voice module, and the indoor air temperature information of acquisition, humidity information, oxygen content information and nitrogen content information are converted to voice by CPU, carry out voice broadcast by Electrical microphone.
Preferably, air purifier of the present invention also comprises WLAN recipient, increases control loading power switch far away, realize the Long-distance Control of air purifier in power control system.
Air purifier of the present invention can realize the automatic control to indoor air temperature, humidity, oxygen content, nitrogen content, improves the comfort level of health.
The foregoing is only preferred embodiment of the present invention, not in order to limit the present invention, within the spirit and principles in the present invention all, any amendment done, equivalent replacement, improvement etc., all should be included within protection scope of the present invention.
