Abstract: This invention relates to a vehicular photoelectron air purifier, and its body is a square-columnar structure comprises extractor fan, transformer, circuit board, and polarization end ultraviolet ray radiation tube. Said body is equipped with one air inlet and one air outlet; said air outlet locates at a front portion of said body and an air exhaust frame trellis device is provided above a front end surface of said body; said air inlet locates at a rear portion of said body and an air intake frame trellis device is provided at a rear portion of said body; said intake frame trellis device provided an air inlet that is used for fixing dustproof frame, dustproof net and dustproof cover; said extractor fan is kept close to the inner surface of said air exhaust frame trellis device, there is an air collector between said air inlet and said extractor fan; said polarization end ultraviolet ray radiation tube lies in s center portion of said air collector.

Abstract: The present invention relates to an air cleaner for killing the bacteria, viruses, mildew in the air with optoelectronic. A draft fan in the main body is used to suck the air. The air is then collected in an air collecting device after passing through an air collecting wall. An extreme ultraviolet ray transmitting tube is used to eliminate the bacteria, viruses, mildew in the air, and thereafter, the cleaned air is disposed by a negative ion cleaner. The fresh air is finally discharged through an air outlet.

Abstract: An air purifier employs photoelectrons to eliminate germs, viruses, funguses and airborne microorganisms or particles in the air comprising a three-dimensional housing 1, an exhaust frame grid 2 at front end of said housing 1, and a rear end of a panel 3. Ionized air is emitted from said exhaust frame grid 2. When said air full of germs, viruses, funguses and other harmful airborne microorganisms or particles in the air moved into an air aggregation wall 26 through said air aggregator 25, and then into said air inlet 7, which is between said ultraviolet radiation tube 21 and said air aggregation wall 26. When said air full of germs, viruses, funguses and other harmful airborne microorganisms or particles in the air, said ultraviolet radiation tube 21 generates extreme ultraviolet to eliminate said germs, viruses, funguses and other harmful airborne microorganisms or particles in the air.

Abstract: A portable photoelectric air cleaner, which includes a semi-circular body in which there are an extractor fan, a transformer, a circuit board, an electrode end ultraviolet radiation tube and a cathode high voltage discharge fibre line, which is characterized in that an air inlet and an outlet are formed on said body. The cathode fibre line for discharging in high voltage is fixed at the air outlet. The electrode end ultraviolet radiation tube is fixed at the outlet which is placed in the body, and is formed in an air collector. The extractor fan is fixed between the electrode end ultraviolet radiation tube and the air outlet which are formed nearly inside the body. The portable photoelectric air cleaner is furthermore characterized in that said air collector is comprised of a space which is defined by an air collecting wall and blocking wall. The electrode end ultraviolet radiation tube is fixed between the front and rear block walls so that the rays can't emit out of the cleaner.

Abstract: A spotlight with locking swivel-join handle includes a lamp head, a handle, a swivel joint for rotatably connecting the handle with the lamp head, and a releasable locking device for selectively locking the handle in a pistol type handle position and a transversal type handle position with respect to the lamp head, wherein in the pistol type handle position, the handle is sidewardly and radially extended from the lamp head, and in the transversal type handle position, the handle is sidewardly extended in parallel with an axis of the lamp head.

Abstract: The present invention relates to an electric lamp, which has a long-life focus lamp, a long-life cold cathode lamp, a long-life siren lamp and a siren for asking for help. The characteristic of the said electric lamp is that the said light source could illuminate continuously over two days with the power supplied by the general battery, and also does not need to replace the lamp within 100,000 hours in use, which could provide to the user with a energy saving, easy to take and asking for help by the siren.
