Abstract

The utility model belongs to the instrument field of environmental protection by people, which is particularly used for decomposing, absorbing and renewing indoor harmful gases. At present, the indoor flue dust cleaning is mostly limited to air exhausting and air inducing, cleaning devices are mostly aimed to remove dust, and the harmful gases are rarely to be eliminated and cleaned. The utility model is composed of a shell, a cleaning cavity, a dust collecting rod and an electronic control circuit, adopting an ionizing method to decompose the harmful gases, and adsorbing the decomposed objects and dust particles simultaneously. The utility model is a new flue dust purifying apparatus which consumes very few energy and which can help non-smokers to get rid of the trouble of passive smoking, the utility model can be widely used for cleaning the flue dust in offices, bedrooms and people carrying rooms of various vehicles.

Description

Ionization type purifier for cleaning room air

The utility model belongs to field of human environmental protection apparatus, particularly to decomposition, absorption and the renewal of indoor harmful gas.

Present indoor clarifying smoke is limited to air draft and air inducing more, and its purifier all is to be purpose with the dedusting, lacks decomposition, absorption and regeneration function to pernicious gas.The weight and volume of these equipment all is very heavy huge, and cost an arm and a leg, energy resource consumption is big.

It is a kind of in light weight that the purpose of this utility model is to provide, volume is little, consumes energy seldom acts on living small environment and little throughput occasion, can remove the infringement to human body of indoor harmful gas and flue dust, has good branch to desorb the indoor smoke and dust purifier of regeneration function.

Design principle of the present utility model is electrochemistry that corona discharge produced and the electric physical action of controlling automatically according to air pollution degree, pernicious gas its analyte and dust granule when ionization is decomposed be adsorbed, and And dispensing negative aeroion is finished to purify and is upgraded.

Agent structure of the present utility model is made up of housing, purification cavity, control of dust rod and electronic control circuit, and housing is the shell of this device, is again the skeleton that supports and connect other parts.Purification cavity, electronic control circuit are contained in the housing, and the control of dust rod is contained in the Shang Fang And and the housing that purify the cavity gas outlet and fixes.

Purifying cavity is the core of this device, and contaminated air promptly is decomposed behind the cavity by purifying, adsorb and purify, and electronic control circuit is used for controlling the Gong that purifies cavity and makes Zhuan Tai And absorption voltage is provided.Connect with the purification cavity by cable or other conductive devices.

The utility model purifies cavity and is formed through the breather line connection by the closed chamber that some permission gases pass through, its end that purifies cavity has a miniature induced-draught fan, the other end is equipped with an ozone adsorbent, and a sensor, corona electrode, netted adsorption electrode and anion pin group are housed in the cavity.

The miniature induced-draught fan of an end that purifies cavity can effectively be accelerated room air and enter cavity and finish purification.Sensor is transformed into the variation by flue dust in the cavity air and pernicious gas content the signal of telecommunication and gives electronic control circuit, makes electronic circuit supply with the required corona current of corona electrode according to the needs that purify.In the chamber of corona electrode, during by normal air, only produce faint ionization, make the air that passes through have an amount of anion, when strengthening by flue dust in the gas of cavity and pernicious gas content, under the effect of electronic control circuit, corona electrode produces the corona discharge of corresponding stage amount, the duty and the air pollution degree of corona electrode are adapted, when discharge is increased to a certain degree, also can produce a certain amount of ozone, can kill bacterium in the air, netted adsorption electrode and ozone adsorbent together, with electrochemical decomposition thing (carbon, sulphur etc.) dust granule and foul smell (O ₃) adsorb to fall; Anion pin group produces anion, and And enters in the room air decompose oxygen that comes out and the fresh air that has an amount of negative aeroion under electrochemical action.

The utility model electronic control circuit is made of sensor, corona discharge control circuit, transistor oscillator, voltage supply circuit and power circuit.The input of the output of sensor and corona discharge control circuit connects, the corona discharge control circuit connects with transistor oscillator, the output and the voltage supply circuit of transistor oscillator link, voltage supply circuit links with the electrode of corona electrode, anion pin group, netted adsorption electrode and control of dust rod respectively again, and power circuit becomes 12 volts of direct currents to 220 volts of alternating currents and supplies with the The whole control circuit.

Sensor is by magnetoelectric conversion element, impedance conversion element or other energy conversion components and support by the dress body and form, and the corona discharge control circuit is by signal coupling capacitance, biasing resistance, amplifier tube, coupling transformer and oscillator bias current adjustment pipe and penetrate a grade output resistance and form.Transistor oscillator is made up of two transistors and transformer.Voltage supply circuit is made up of commutation diode and capacitor, and power circuit is by transformer, and commutation diode and filter capacitor are formed.

The utility model is the novel indoor air device that people provide that a kind of volume is little, in light weight, consumes energy is few, can dedusting can decompose, adsorb and upgrade pernicious gas again.
