Detailed Description
In order to make the objects, technical solutions and advantages of the present invention more apparent, embodiments of the present invention will be described in detail with reference to the accompanying drawings.
As shown in fig. 1, an embodiment of the present invention provides a vehicle-mounted air sterilizer, which includes an air outlet assembly 1, a light shield 2, an anion generator 3, a fan 4, an upper case 5, and a lower case 6.
The lower end of the air outlet component 1 is provided with an outward buckle, and the air outlet component 1 is arranged at the upper end of the upper shell 5 through the buckle. The lower end of the upper shell 5 and the upper end of the lower shell 6 are provided with mutually corresponding buckles, and the upper shell 5 and the lower shell 6 are fixedly connected through the buckles to form a containing cavity.
As shown in fig. 2, the air outlet component 1 is composed of a start button 11, a UVC lamp 12, a PCBA plate 13, a limiting ring 14, an air outlet deflector ring 15 and an air outlet component housing 16. A base 151 is arranged at the center of the air outlet deflector ring 15, the UVC lamp 12 is mounted on the PCBA board 13, then the PCBA board 13 can be mounted in the base 151, and the start button 11 is sleeved on the base 151. The outer side of the air outlet flow guide ring 15 is further provided with a plurality of clamping grooves 152, the limiting ring 14 is installed in the clamping grooves 152, and the air outlet component shell 16 is sleeved outside the air outlet flow guide ring 15. The lower end of the air outlet component 1 is also provided with an inward buckle, and the light shield 2 is arranged inside the lower end of the air outlet component 1 through the buckle. The lens hood 2 can block ultraviolet rays emitted by the UVC lamp 12, and meanwhile, the effect of structural support can be achieved, and the overall strength of the air outlet assembly 1 is enhanced.
The negative ion generator 3 and the fan 4 are sequentially arranged in the accommodating cavity in the upper shell 5 from top to bottom. The fan 4 can suck air in the vehicle into the vehicle-mounted air sterilizer from an air inlet at the lower end of the lower shell 6. Various harmful gases and substances in the gas, such as smoke, dust, automobile exhaust, odor, formaldehyde, benzene, ammonia and other chemical substances, and electromagnetic waves generated by various electronic products and electric appliances such as TV, PC, mobile phone and the like in daily life generally exist in the form of positive ions. The air entering the vehicle-mounted air sterilizer is ionized by the negative ion generator 3 to generate negative ions, so that positive ions can be neutralized, active oxygen free radicals generated by pollutants, nitrogen oxides, formaldehyde, cigarettes and the like from the atmosphere can be reduced, and positively charged air floating dust can be settled after being uncharged. In addition, the binding of negative ions to bacteria can cause structural changes or energy transfer to the bacteria, resulting in bacterial death.
The fan 4 can also accelerate the air flow in the automobile, and blows the negative ions generated by the negative ion generator 3 to all parts in the automobile, so that the negative ions are fully combined with harmful substances in the air, and the harmful substances such as formaldehyde, benzene, dimethylbenzene, dust, germs and the like in the automobile can be removed.
In one embodiment of the invention, a 185nm wavelength UVC lamp 12 may be selected. The ultraviolet ray with the wavelength of 185nm changes oxygen in the air into ozone, and the strong oxidation effect of the ozone is utilized to sterilize, so that the defects that the ultraviolet ray only transmits along a straight line and has dead angles in sterilization can be overcome. However, ozone is blown into the vehicle along with the function of the fan 4, which easily stimulates the respiratory tract of people, causes sore throat, chest distress and cough, causes bronchitis and emphysema, and also causes people neurointoxication under severe conditions, and causes symptoms such as dizziness and headache, visual deterioration, memory deterioration, shortness of breath, fatigue, nosebleed and the like.
Ultraviolet rays with the wavelength range of 200-275 nm of UVC can directly damage chromosomes of microorganisms to kill bacteria, the sterilization effect is good, and harm to a human body can be avoided after the UVC lamp 12 is turned off. In consideration of the fluctuation of the process parameters, the present invention selects the UVC lamp 12 with the wavelength of 265-280 nm.
In order to prevent ultraviolet rays from leaking to the outside of the vehicle-mounted air sterilizer through direct radiation, reflection and refraction during the operation of the UVC lamp 12, the inner walls of the upper shell 5 and the lower shell 6, and the inner wall of the air outlet assembly 1 and the light shield 2 are coated with anti-UV coatings, respectively. The anti-UV coating is a mixture of an ultraviolet light absorber UV531 and an ultraviolet light stabilizer HTP in a mass ratio of 1:1, wherein the mass fraction of the ultraviolet light absorber UV531 is 0.5%, and the thickness of the coating is 10-20 microns.
Still install air filter 7 in the inside holding chamber of inferior valve 6, air filter 7 is cellular detachable, can get 7 with air filter and take out to wash or change after long-time the use. The air filter element 7 can adopt an active carbon filter element or a HEPA composite filter element. The active carbon has rich pore structure and extremely high specific surface area, so the active carbon has good adsorption property and can treat pollutants in the air through physical and chemical adsorption. The HEPA filter element is a recognized high-efficiency filter material, has the removal efficiency of particles with the diameter of less than 0.3 micrometer of more than 99.7 percent, is the most effective filter medium for pollutants such as smoke, dust, bacteria and the like, and is widely applied to high-cleaning places such as operating rooms, animal laboratories, crystal experiments, aviation and the like. The air filter element 7 can also block the air inlet of the lower shell 6, so that the ultraviolet rays can be blocked from leaking.
The vehicle-mounted air sterilizer can be designed into a cylinder or a cuboid according to actual requirements, and correspondingly, the air outlet component shell 16, the upper shell 5 and the lower shell 6 can also be correspondingly designed into a cylinder or a rectangle. Of course, the vehicle-mounted air sterilizer of the present invention can be designed in other shapes, which are not illustrated herein.
When the vehicle-mounted air sterilizer works, the fan 4 is started, air in a vehicle is sucked into the vehicle-mounted air sterilizer from the air inlet at the lower end of the lower shell 6, after the air is filtered by the air filter element 6, the negative ions generated by the negative ion generator 3 and the ultraviolet rays emitted by the UVC lamp 12 are purified and sterilized, and the treated air is discharged from the upper end of the air outlet assembly 1 and returns to the interior of the vehicle.
In the embodiment of the invention, the vehicle-mounted air sterilizer comprises an air outlet assembly, a light shield, a negative ion generator, a fan, an upper shell and a lower shell; the lower end of the air outlet assembly is provided with a buckle, the light shield is installed inside the lower end of the air outlet assembly through the buckle, and the air outlet assembly is installed at the upper end of the upper shell through the buckle; the upper shell and the lower shell are fixedly connected in a buckling mode to form an accommodating cavity, and the negative ion generator and the fan are sequentially installed inside the upper shell from top to bottom.
