Description
Technical Field
The utility model belongs to the technical field of auto-parts technique and specifically relates to an automobile-used portable air purifier.
Background
Automobiles have become indispensable vehicles in daily life, and the air quality in the automobiles is receiving attention from people.
The car of the automobile obtains outside air through a ventilation system of the automobile, so that the aim of ventilation is fulfilled. Generally, a ventilation system of a vehicle is provided with a filter, and filtered air is supplied into a car. In order to achieve a better purification or air conditioning effect, the ventilation systems of some vehicles also support switching between cabin air internal circulation and cabin external air exchange.
The environmental pollution of the vehicle interior alone is caused by the external air entering the vehicle interior when the vehicle is in the air conditioning external circulation state. Outside air enters the vehicle and firstly passes through an air conditioner filter in the vehicle, but the existing common air conditioner filter can only filter dust and pollen with the particle size of more than 5 microns, and cannot be used for PM 2.5. Therefore, in the face of increasingly serious PM2.5 pollution, the existing in-vehicle air purification system cannot meet the requirement of fresh environment in the vehicle only by relying on a pure air conditioner filter. On the other hand, the material of the automobile itself may emit gaseous pollutants due to aging. Due to the existence of the two pollution modes, pollutants in air in a vehicle with a sealed space are gradually increased along with the prolonging of the running time of the vehicle, and the body discomfort of a driver or passengers can be caused if the pollutants cannot be filtered or discharged in time, so that the body health of the driver or the passengers is not good.
Disclosure of Invention
The utility model aims at providing an automobile-used portable air purifier further improves the interior air quality of car.
In order to achieve the above object, the technical solution of the present invention is to provide a portable plasma air purifier for vehicles, which comprises a high-frequency high-voltage power supply, a plasma generator, and is characterized in that: the input power supply of the high-frequency high-voltage power supply is an automobile direct-current power supply, electricity is taken from an automobile cigarette lighter, the plasma generator is composed of a discharge probe and a discharge screen, the negative end of the high-frequency high-voltage power supply is electrically connected with the discharge probe, and the positive end of the high-frequency high-voltage power supply is electrically connected with the discharge screen through a work indicating device.
In the technical scheme, the high-frequency high-voltage power supply adopts a self-oscillation transformer coupled current negative feedback inverter circuit, and a ferrite full-rubber-sealed micro transformer boosts the voltage.
In the technical scheme, the power supply inversion frequency of the high-frequency high-voltage power supply is 6.0KHz to 28.0 KHz.
In the above technical solution, the vertical discharge distance between the discharge probe and the discharge grid plate is 3.0mm to 7.0 mm.
The utility model has the advantages that 1, electricity is taken from the cigarette lighter jack of the automobile, which is convenient and fast; 2. according to the size of the car space, the size of the power supply inversion frequency and the distance between the discharge probe and the discharge grid plate can be selected to adjust the scale of the Terrichel corona discharge. 3. The air filter of the car can be used for improving the air quality in the car under the combined action of the air filter of the car, and particularly, the air filter of the car is not enough.

Fig. 1 is a schematic structural diagram of the present invention.
In the above drawings, 1 is a power-taking anode, 2 is a power-taking cathode, 3 is a high-frequency high-voltage power supply, 4 is a negative high-voltage discharge probe, 5 is a positive high-voltage discharge screen, 6 is a work indicator, 7 is a shell, 8 is a spring, and 9 is overload protection.
Detailed Description
The embodiment of the utility model discloses automobile-used portable plasma air purifier structure is shown as attached figure 1.
The power access device of the embodiment is composed of a power taking anode 1 and a power taking cathode 2, wherein the root of the power taking anode 1 is provided with a spring 8, the power taking cathode 2 is made of elastic metal materials, direct current can be conveniently obtained from a jack of an automobile cigarette lighter and sent to a power input end of a high-frequency high-voltage generating power supply circuit, the high-frequency high-voltage generating power supply 3 adopts a self-excited oscillation type inverter circuit, a micro ferrite transformer is used for boosting, the high-frequency high-voltage generating power supply 3 generates negative high voltage of about 6.8Kv with the frequency of about 13KHz and transmits the negative high voltage to a negative high-voltage discharge probe 4, and the anode end of the high-frequency high-voltage generating power supply 3. The distance between the needle tip of the negative high-voltage discharge probe 4 and the positive high-voltage discharge screen 5 is 5.1mm, and the discharge distance can be preset in the production process. The work instruction 6 adopts a high-voltage electrostatic induction coupling type to get electricity. The Terrichel corona discharge is formed between the negative high-voltage discharge probe 4 and the positive high-voltage discharge screen 5, so that the toxic and harmful gases and the peculiar smell in the air inside the car can be eliminated and purified, and the function of automatically regulating and increasing negative oxygen ions is realized. The overload protection 9 is a common fuse, which is fused and broken when overloaded.
The whole structure of the embodiment is simple and reasonable, and the plasma density and the positive and negative ion concentration ratio generated by the product can be preset by setting the inversion frequency of the high-frequency high-voltage power supply and the discharge distance between the negative high-voltage discharge probe 4 and the positive high-voltage discharge screen 5.
