Abstract

The utility model discloses a multifunctional portable detector used in daily life, wherein a fluorescent light and an electric moisture detecting circuit are simultaneously disposed in a small portable outer casing of the detector. The fluorescent light can emit ultraviolet light wavelength in a certain range after power is on, and as RMB and various foreign currency are respectively equipped with a specific fluorescent stamp, counterfeit currency can be identified by detection of ultraviolet light. The electric detecting circuit uses a 555intergal circuit as a core element, after inserting a probe in an object-to-be-detected, difference of conducting resistance in the probe is decided by moisture content contained in the object-to-be-detected, and comparing the resistance with the preset safety value, a green light can be lightened if moisture content is lower than the safety value while a red light can be lightened if moisture content is higher than the safety value. When using to test meat, water content is within limits when the green light is lit while water content is out of limits when the red light is lit, further, when using to test fruits, water content is judged to be lower than limits when the green light is lit while water content is judged to be sufficient when the red light is lit.

Description

The multifunctional portable detecting device

Technical field

The utility model relates to a kind ofly judges that some article has or not ad hoc fluorescence reaction and judges whether normal small-sized multifunctional portable detecting device of some article water cut.

Background technology

The development of current social science and technology is swift and violent, and our daily life just is being subjected to scientific and technical omnibearing challenge.We on one side can happy announcing: " science and technology changes life, science and technology increases happiness "; But the complaint of also usually being indignant simultaneously: " science and technology upsets life, science and technology increases worry ".The for example appearance of water-injected meat has just been added many worries to the consumer.Do not take for water-injected meat and exactly meat is soaked in water, absolutely not so simple.It is before livestock is not also slaughtered, and just irritates the water of excess atrociously in its stomach, and allows water deposit stomach to reach tens of hours, because this moment, livestock was dead, so large quantity of moisture will penetrate into all internal organs and whole musculatures along big and small vessel.Be full of ferment the under one's belt in a large number internal organ and the muscle of dirty moisture, not only be to have increased useless weight, more seriously endanger the healthy of eater greatly!

How is present people differentiate water-injected meat? normally by experience: mainly be its look of sight, touch its matter, stick thieving paper or the like, but these means reliabilities are not high, moreover ordinary consumer also is difficult to learn smart; Yet the professional detecting device of administrative department of government is not only expensive, and operation is also complicated, spreads to for no reason at all in every consumer's hand.

Also have spreading unchecked of counterfeit money, among the people in small-sized transaction, the easy more harassment that suffers counterfeit money makes ordinary consumer not only vexatious but also feel hard to guard against deeply! The coin machine of testing of those specialties all is placed in the mechanisms such as bank, supermarket, be not easy to certainly allow the consumer everybody carry, in time detect.It is indefinite, relieved inadequately usually to hold by experience differentiation counterfeit money.

Looked into multiple data, and still do not have the portable detecting device that integrates these two kinds of functions and be disclosed.

Summary of the invention

For the instrument of a self-protection easily is provided to ordinary consumer; the purpose of this utility model is that a kind of multi-functional portable small detector is provided; it both can make things convenient on the fast detecting coin ad hoc fluorescent characteristic; can also make things convenient for fast detecting meat water cut whether to exceed standard, also can make things convenient for some fruit water cut of fast detecting whether ultralow.

The technical scheme that this technical matters that solves the utility model adopts is: the two groups of electronic components of in special compact shell, packing into, and one group provides outside ejaculation ultraviolet light, and one group provides water content detection.Ultraviolet light is made of power supply, pushbutton switch and the light emitting diode that can send ultraviolet light, and moisture content detection device is made of with light emitting diode power supply, push switch, application-specific integrated circuit, adjustable resistor, demonstration.

It is as follows to detect the coin principle: under the ultraviolet light irradiation, the privileged site of genuine note can occur significantly, the fluorescence marking clearly, be provided with fluorescence digital as version in 1999 and position, the positive middle and upper part of version Renminbi in 2005, cannot see under the ordinary light, only under UV-irradiation, just can show; The multicolour pattern at the back side can show sightless fluorescent orange under the ordinary light in that ultraviolet light irradiation is next; Counterfeit money or do not have fluorescence marking pattern, otherwise dim pattern is unclear, otherwise its coin paper can reflect ultramarine light, is easy to differentiate distinguish.Various in the world foreign currencies also all have the specific fluorescent marking separately.

It is as follows to detect the moisture principle: a pair of probe is inserted measured object, conduction resistance difference between measured object contained humidity number decision probe, this resistance value is compared with predefined safety value, if moisture is lower than the safety value green light and lights, moisture is higher than the safety value red light to be lighted, and judges whether the measured object water cut exceeds standard or ultralow with this.The core electron element of realizing this function has adopted and has been called as 555 integrated circuit, as long as this integrated circuit is mixed different annexes, adopt different methods of attachment just can obtain different functional modules, connection is with 2 herein, 6 pin and connect the back between 1 pin, constitute probe, at this moment resistance value between probe is connected to the ruddiness Guan Liang of 3 pin if just export high level less than setting value 3 pin; If at this moment resistance value between probe is connected to the green glow Guan Liang of 7 pin greater than just output low level of setting value 7 pin; The default employing rotation adjustable resistance TW of setting value determines, promptly insert in advance set up to critical conditions in the known aqueous normal goods stand-by.Obviously, detect dissimilar article and should set different setting values.

The beneficial effects of the utility model are: allow vast ordinary consumer conveniently carry the multifunctional portable detecting device of indication, at any time can differentiate the coin true and false fast, differentiate fast whether excessive water filling of meat, whether fresh, thereby being unlikely in daily life to jump at the bait is deceived if understanding some fruit fast.
