Abstract
The utility model discloses a detecting device for a thermistor of an air conditioner. The detecting device comprises a difference comparison circuit box, a sampling jack, a test jack and an alarm and is characterized in that the sampling jack, the test jack and the alarm are arranged on the surface of the difference comparison circuit box; and the difference comparison circuit box consists of a box body and a difference comparison circuit, wherein the difference comparison circuit is arranged in the box body. The detecting device is not influenced by the condition that the resistance value of a temperature sensing resistor changes along with the change of temperature and is accurate, simple and rapid in judgment, and thus, the problem that the test is not easy because a temperature sensing head changes along with the temperature is thoroughly solved.
Description
Technical field
The utility model relates to resistor detecting device, particularly a kind of air conditioner thermistor pick-up unit.
Background technology
In producing air conditioner in the process of bulb, because that temperature-sensitive head exists outward appearance is the same, the resistance of various models is different, and the capacity batch mixing adds that supplied materials also has underproof phenomenon, so must the supplied materials of bulb be detected.In order to address this problem, can detect underproof temperature-sensitive head in advance, I detected according to the common method that detects resistance-multimeter company in the past.Send the special messenger to measure with multimeter.But there is following shortcoming with the multimeter measurement: because the response speed of multimeter is slow,, must drop into great amount of manpower and accomplish this work; The cumbersome member of multimeter measuring operation, the worker makes mistakes easily, inefficiency; This temperature-sensitive head is to be made by thermistor, and the resistance of thermistor is to change with temperature variation, and the resistance of a temperature-sensitive head in the no time also is different, and it is qualified just can not to judge whether very accurately with multimeter, and the phenomenon of erroneous judgement is often arranged.
Summary of the invention
The purpose of the utility model is to above-mentioned technical disadvantages a kind of air conditioner thermistor pick-up unit to be provided, and through adopting the difference comparator circuit, has solved the problem that temperature-sensitive head is not easy to test with temperature variation.
The technical scheme of the utility model is following: a kind of air conditioner thermistor pick-up unit; Form than circuit box, sampling socket, testing jack, alarm by differential ratio; Its characteristics are: at differential ratio sampling socket, testing jack and alarm are housed on than the circuit box face; Said differential ratio is to be made up of casing, difference comparator circuit than circuit box, and the difference comparator circuit is contained in the casing.
Described sampling socket is contained in differential ratio than on the circuit box, links to each other with sample circuit in the difference comparator circuit.
Said testing jack is contained in differential ratio than on the circuit box, links to each other with metering circuit in the difference comparator circuit.
Described alarm is contained in differential ratio than on the circuit box, links to each other with driving amplifying circuit in the difference comparator circuit.
The beneficial effect of the utility model is: a kind of air conditioner thermistor pick-up unit; Through adopting differential ratio than the drives alarm equipment alarm, use this device to test time to need only 0.1 second, improved production efficiency greatly; Originally 3 people's work; Present 1 people just can be competent at, accuracy of judgement, rapidly simple, and can thoroughly solve the problem that temperature-sensitive head is not easy to test with temperature variation.
Description of drawings
Below in conjunction with accompanying drawing and embodiment the utility model is further specified.
Fig. 1 is the structural representation of this utility model.
Fig. 2 is that the differential ratio of this utility model is than circuit theory diagrams.
Among the figure, 1 be differential ratio than circuit box, 2 for the sampling socket, 3 is testing jack, 4 is alarm, 5 is casing, 6 is the difference comparator circuit.
Embodiment
Be described further below in conjunction with the embodiment of accompanying drawing the utility model:
In Fig. 1, a kind of air conditioner thermistor pick-up unit is made up of than circuit box 1, sampling socket 2, testing jack 3, alarm 4 differential ratio, and its characteristics are: than on 1 of the circuit box take a sample socket 2, testing jack 3 and alarm 4 are housed at differential ratio.
Described differential ratio is to be made up of casing 5, difference comparator circuit 6 than circuit box 1, and difference comparator circuit 6 is contained in the casing 5.
Described sampling socket 2 is contained in differential ratio than on the circuit box 1, links to each other with the sample circuit of 6 li of difference comparator circuits.Sampling socket 2 is used for inserting sample thief.
Described testing jack 3 is contained in differential ratio than on the circuit box 1, links to each other with the metering circuit of 6 li of difference comparator circuits.Testing jack 3 is to be used for inserting getting the thermistor that needs to measure.
Described alarm 3 is contained in differential ratio than on the circuit box 1, links to each other with the driving amplifying circuit of 6 li of difference comparator circuits.Earlier qualified sample is inserted on the sampling socket 2 before test begins, the thermistor that needs are measured is inserted on the measurement socket 3; Each so measured resistance all compares with the qualified sample of standard, opens differential ratio than circuit box 1, sample circuit, metering circuit respectively will be separately the resistance of sample resistance and measuring resistance be converted into electric signal; Comparator circuit just can be with the difference signal of sample resistance and measuring resistance resistance; Subdue the back and extract phase difference signal, this phase difference signal and sample resistance and measuring resistance resistance extent mutually are directly proportional, and fair receipts scope and electric signal that controller is responsible for definite measuring resistance differ big or small; The signal that instruction driving amplifying circuit will exceed disparity range amplifies; To drive alarm 4 work, realize the warning of bright lamp or buzz, just do not pass through otherwise do not report to the police.。
Through above embodiment, the utility model is when temperature variation, and the resistance of sample and test block all changes simultaneously, and this is with regard to the thorough problem that temperature-sensitive head is not easy to test with temperature variation, the accuracy of judgement, rapidly simple of having solved.
