CN2191666Y - Ultraviolet sterilizer for vehicle - Google Patents

Abstract

The utility model relates to an ultraviolet sterilizer which is particularly used for vehicles, and is composed of an ultraviolet lamp tube, a light fixture, a power control device and mounting components which are connected to form an entirety. A power control device is composed by connecting a timing circuit, a single tube amplifying circuit and an oscillating circuit for changing the 12V direct current of a vehicle into HVAC in sequence. The lamp tube radiates ultraviolet rays during definite-time. When the definite-time is over, sterilization is stopped. The sterilization and the disinfection of general vehicles can be satisfied by adopting an 8-15W ultraviolet lamp tube to work for 45 minutes. A hook, a clamp, a magnet or a double face contact can be adopted by the mounting components to be convenient for being fixed and used.

Description

Ultraviolet sterilizer for vehicle

This utility model relates to a kind of disinfection apparatus of object, relates to a kind of ultraviolet disinfection decontaminating apparatus or rather.

Raising along with the social civilization degree, the health of living environment more and more causes people's attention, everyone wishes that own residing environment meets sanitary standard as far as possible, but as public transports such as bus, taxi, ambulance, environmental sanitation clearing and transporting vehicle, funeral and interment car, industry engineering truck, touring cars, all have every day patient to take unavoidably or vehicle travels through uncleanly environment, pathogenic bacteria remains in the car in the air and handrail, seat on; The environment of air-conditioned coach also is particularly suitable for bacteria live, has a large amount of mycetes and germ reproduction in the car, especially has a humid climate or season of disease transmission, and common carriage just becomes the place of various diseases cross infection, the health that is constantly threatening people.

The purpose of this utility model is to design a kind of ultraviolet sterilizer of special use for the public transportation instrument, uses 12V power supply in the car, has installation, characteristics easy to use.

Automobile-used ultraviolet sterilizer of the present utility model is made of ultraviolet radiation light source, light fixture and the power control circuit box that is connected with the ultraviolet radiation light source, it is characterized in that:

Described light fixture is fixedly mounted on the described power control circuit box;

Also be fixed with hook or clip or magnetic piece or two-sided subsides installing component on the described power control circuit box;

The power control circuit of described power control circuit box is linked in sequence by timing circuit, single-valve amplification circuit with the oscillating circuit that the automobile storage battery DC voltage changes ac high-voltage into and constitutes.

The quartz ultraviolet ray fluorescent tube that described ultraviolet radiation light source is 8-15W.

Described light source and lamp locker have for the spiral direction transducer of regulating the fluorescent tube direction.

Installing component by sterilizer is fixed on any position in the car with sterilizer, closed on and off switch, in timing, light the quartz ultraviolet ray fluorescent tube, the radiation ultraviolet, and, can kill various funguses, antibacterial, virus with the ozone generation, timing is to the power supply of cutting off the quartz ultraviolet ray fluorescent tube automatically.

Further specify technology of the present utility model below in conjunction with the embodiment accompanying drawing

Fig. 1. automobile-used ultraviolet sterilizer surface structure sketch map 1

Fig. 2. automobile-used ultraviolet sterilizer surface structure sketch map 2

Fig. 3. the power control circuit first embodiment electrical schematic diagram

Fig. 4. the power control circuit second embodiment electrical schematic diagram

Referring to Fig. 1,1 is light fixture among the figure, and 2 is the quartz ultraviolet ray fluorescent tube, and 3 is the power control box of fluorescent tube, and 4 is installing component.Installing component can be just like illustrated coupling type, or various ways such as clamp type, magnet-type, two-sided subsides, can or be placed on certain position in the automobile sterilizer suspension or clamping or attaching.Power control box and light fixture can be bonding or be screwed into one.Operating switch K1 and relay indicating light L are arranged on the power control box, and fluorescent tube adopts the quartz ultraviolet lamp of 8-15W.

Burdick lamp can be emitted an amount of ozone when sterilization, experiment shows that each sterilization can reach bactericidal effect in 45 minutes, and the sterilization operation stops back 15 minutes institute's ozone of putting with regard to reducible one-tenth oxygen.

Referring to Fig. 2,5 is H type quartz burner among the figure, and light fixture 6 in the power control circuit box of holding concurrently has spiral direction transducer 7, and this direction transducer 7 makes fluorescent tube 5 can make 180 ° of directions and regulates, and 8 be that base, 9 is an installing component.

Referring to Fig. 3, constitute timing circuit by time-base integrated circuit 555 and peripheral resistance thereof, electric capacity, audion T1 and peripheral resistance thereof constitute single-valve amplification circuit, high power transistor T2(325), pulse transformer B1 and peripheral resistance thereof, electric capacity constitute auto-excitation type single tube LRC oscillating circuit, the 12V direct current is transformed into High Level AC Voltage, drive point brilliant violet outside line fluorescent tube M1 or M1, M2.K switch 2 is used to select to insert fluorescent tube M1, the M2 of two serial connections or only select M1.The permeability of pulse transformer B1 magnetic core is used greater than 5000

Be 0.41 and enamel-covered wire coiling on EI shape magnetic core of 0.15mm form, L1 is 25 circles, L2 is 40 circles, L3 is 600 circles.

Closed on and off switch K1, the timing circuit output low level, T1 ends, the T2 conducting, oscillating circuit work is about fluorescent tube starting resistor 1200V, about running voltage 100V.Transistor operating frequency 30KHZ.Timing arrives, 555 3 feet output high level, and T1 conducting control T2 ends, and oscillating circuit is not worked, and cuts off tube power automatically and stops sterilization.

During enforcement, also on and off switch K1 can be arranged on by the car door, the staff leaves vehicle at closing time, connects the sterilizer power supply automatically, in order to avoid ultraviolet direct irradiation human body stimulates eyes, skin.

Referring to Fig. 4, the operation principle of circuit shown in Figure 4 and enforcement circuit thereof are similar to Fig. 3 substantially, but pulse transformer B2 adopts from the Rhizoma Nelumbinis connected mode in the oscillating circuit, and the B2 coil winding is substantially with embodiment 1.

The foregoing description oscillating circuit, transformer-secondary voltage height (1200V) when open circuit helps puncturing quartz burner, in case can keep lower light tube electric voltage (100V) after puncturing, has from the current stabilization effect, has the characteristics of reliable operation.

Kill various antibacterials with ultraviolet, can not pollute, have effects such as sterilization, sterilization, removal abnormal flavour, use 12V power supply in the car, install, use all very convenient environment.
