Description

Stepup transformer and negative ion output line pick-up unit

Technical field

The invention belongs to the sterilization of air, sterilizing or field of deodorization, be specifically related to a kind of stepup transformer and negative ion output line pick-up unit.

Background technology

China is one of country that urban air pollution is the most serious in the world.The city that 10 large air pollutions are the most serious in the world has 7 to be in China, and its pollution level has exceeded the standard of World Health Organization's defined.Air pollution can cause bronchitis, coronary heart disease, heart failure, tuberculosis, angiocardiopathy etc., and research shows that the mean lifetime of the mankind is because air pollution has probably shortened 5 years half.

The current air purifier having occurred purifying air, also known as " air cleaner ", can adsorb, decomposes or transform various air pollutants, and effectively improve air cleanliness.Air purifier is mainly divided into passive type, active and active/passive three class, and passive type is mainly through strainer filtering air; Active, initiatively in air, discharge the purifying and sterilizing factor, as negative ion, silver ion etc.; Active/passive is then by passive type and active combination.

Active with in active/passive two class air purifier, effect is it is preferred that negative ion air-cleaner, its principle is as follows: low-voltage is risen to negative direct current high voltage by stepup transformer by negative oxygen ion generator, needle point or the most advanced and sophisticated high direct voltage of carbon brush is utilized to produce high corona, release a large amount of negative charges at high speed, and negative charge cannot be present in air for a long time, and can be caught by the oxygen molecule in air at once, form negative ion, the phenomenon producing negative ion when principle and spontaneous phenomenon " thunder lightning " is identical.

After negative ion air-cleaner work a period of time, stepup transformer can go bad, thus causes the voltage at needle point or carbon brush tip to reduce, and the negative ion of generation reduces, and does not even produce negative ion.Because stepup transformer and needle point or carbon brush tip are positioned at negative ion air-cleaner inside, and the negative ion launched is invisible, so be difficult in user's use procedure judge whether negative ion air-cleaner normally works.

Summary of the invention

For the defect that above-mentioned prior art exists, the object of the present invention is to provide one can detect stepup transformer and whether normally work, and anion-generating capacity is in stepup transformer and the negative ion output line pick-up unit of normal level.

For achieving the above object, technical scheme of the present invention is: stepup transformer and negative ion output line pick-up unit, wherein, comprise the holder of the metal wire of conduction, voltage measuring instrument, output line and metal wire, the input end of described voltage measuring instrument is connected with metal wire one end, voltage measuring instrument output head grounding, described metal wire, high-voltage output line are arranged in parallel in holder.

When adopting technique scheme, after voltage raises by stepup transformer, voltage can reach 3 ~ 10kv usually, some is even higher, then export through high-voltage output line, and produce high corona at output terminal, release a large amount of negative charges at high speed, the high pressure of high-voltage output line can be responded at high-voltage output line side metal wire, electronics displacement in metal wire, thus generation voltage, the induced voltage size on metal wire is detected by voltage measuring instrument, if when stepup transformer normally works, the voltage that metal wire senses is in certain scope, if when stepup transformer goes bad, the voltage that metal wire senses just exceeds above-mentioned scope, like this by detecting induced voltage size on metal wire whether in above-mentioned scope, just can judge whether stepup transformer normally works, thus indirectly judge whether anion-generating capacity is in normal level.

Further, described metal wire is copper cash.The electric conductivity of copper is only second to the silver of electric conductivity the best, can induced voltage better, so can be convenient to detect.

Further, described holder comprises base and is located at four reference columns by rectangular arrangement on base, and described output line is arranged along two reference columns, and walks around reference column respectively, and described metal wire is arranged along another two reference columns, and two ends are around on reference column.After corresponding reference column walked around respectively by output line, metal wire, can make to be in parastate all the time between output line, metal wire, and position stability, thus the magnitude of voltage that voltage measuring instrument detects is more accurate.

Further, described base is provided with two bar-shaped troughs, and two reference columns being wound around metal wire are arranged in two bar-shaped troughs respectively, and one end of bar-shaped trough is provided with the set screw coordinating and regulate reference column.So just can regulate the position of the reference column being wound around metal wire, thus change the spacing of metal wire and output line, be convenient to measure the voltage on metal wire.

Further, described wire lengths is 20cm, and the spacing of metal wire and output line is 3mm.Inventor finds through overtesting, and detecting by above-mentioned condition the copper cash voltage that obtains can better for judging that whether stepup transformer is normal, and whether anion-generating capacity is in normal level.
