CN2580449Y - Digital electric test pencil with back-note detection function - Google Patents

Abstract

The utility model discloses a digital electricity testing pen with a banknote detection function, which is composed of a pen head (1) and a pen body (2). The digital electricity testing pen with a banknote detection function is characterized in that a circuit for banknote detection is arranged inside the pen body and is connected with a purple light diode (7) outside the pen body, and a voltage measuring part which comprises an inside cell box (8), a circuit board (9), and a liquid-crystal display screen (3) which is connected outside the pen body is also arranged. When the digital electricity testing pen with a banknote detection function works, a power supply is switched on, and the purple light diode (7) is brightened. The banknotes can be detected. If the pen head is contacted with a fire wire, the magnitude of the voltage on the liquid-crystal display screen can be read out by touching a direct key with a finger. The digital electricity testing pen with a banknote detection function has the advantages of small size and convenient carrying. The digital electricity testing pen with a banknote detection function brings convenience to daily life.

Description

A kind of digital test pencil with cash examining function

1, affiliated technical field:

The utility model relates to a kind of test pencil.

2, technical background:

In daily life, along with popularizing and widespread use of electric energy, people often run into such situation, and that needs exactly to know whether certain part article is charged, perhaps needs to know the size of voltage, and this has just used test pencil.Known test pencil application principle is roughly all identical with internal structure, mainly constitute by the metal key-press of outside and inner conductive adhesive tape, circuit board etc., in the middle of test, metal sensor key with the finger touch outside also will stretch out the pen head part of electroprobe near live wire, the display part can show charged sign, expression has electricity, is live wire; If ground wire does not then have demonstration.But known test pencil function is comparatively single, the one, can not show the size of the voltage of surveying, and make troubles to use, the 2nd, be difficult for carrying, except surveying electricity, there are not other functions again.3, the content of innovation and creation:

1., the purpose of utility model:

The purpose of this utility model promptly is to provide a kind of miniature digital test pencil with cash examining function, and it one is the size that can measure voltage at an easy rate, and is easy to use, and the 2nd, volume is little, and is portable, can check the true and false of banknote at one's side at any time.

2., utility model technical scheme:

The utility model mainly partly is made up of a nib and a body, and pen head part is the same with known technology, makes screwdriver-like by metal material, can be used to the dismounting screw; Body partial interior is equipped with circuit board, battery case, switch sections, and circuit connects outside LCDs and violet light diode and switch, also has a direct key and a sensor key.When work, the Push switch part gets final product energized, forms the loop, and violet light diode is bright, can utilize a certain position of violet light diode irradiation banknote, just can debate other authenticity of banknotes.When surveying voltage, the live wire of the nib contact power supply of surveying, in addition with the direct key of finger touch, the size that can show the voltage of surveying on the LCDs, if with the finger touch sensor key and with the close live wire of nib, can demonstrate the lightning sign on the LCDs, expression has, be live wire, ground wire does not then have demonstration.

3., the beneficial effect that reaches:

According to the utility model of said structure, have currency examine simultaneously and survey the electric work energy, and the accurate measuring voltage of energy, volume is little, is easy to carry, and has brought convenience to life.

4, description of drawings:

Below in conjunction with accompanying drawing the utility model is explained detailedly.

Fig. 1 is the utility model appearance assumption diagram;

Fig. 2 is the utility model longitudinal diagram;

Fig. 3 is a currency examine partial circuit schematic diagram.

Nib in the drawings, 1; 2, a body; 3, LCDs; 4, on ﹠ off switch; 5, direct key; 6, sensor key; 7, violet light diode; 8, battery case; 9, circuit board.

5, embodiment:

The utility model mainly is made up of nib 1 and a body 2 parts, and written 1 part is the same with known technology, makes screwdriver-like by metal material, can be used to the dismounting screw; Body 2 partial interiors are equipped with circuit board 9, battery case 8, switch sections 4, and circuit connects outside LCDs 3 and violet light diode 7 and switch, also have a direct key 5 and a sensor key 6.When work, the Push switch part gets final product energized, forms the loop, and violet light diode 7 is bright, can utilize a certain position of violet light diode irradiation banknote, just can debate other authenticity of banknotes.When surveying voltage, the live wire of the nib 1 contact power supply of surveying, in addition with the direct key 5 of finger touch, the size that can show the voltage of surveying on the LCDs 3, if with finger touch sensor key 6 and with the close live wire of nib, can demonstrate the lightning sign on the LCDs, expression has, be live wire, ground wire does not then have demonstration.

Claims (1)

1. A kind of digital test pencil with cash examining function, form by nib (1) and a body (2) two parts, it is characterized in that: there is LCDs (3) a body outside, directly there are battery case (8), circuit board (9) in key (5), sensor key (6), violet light diode (7), inside, the break-make of outside on ﹠ off switch control power supply.
