Abstract
The utility model discloses a dust-proof test box with a humidity measurement function. The measurement system comprises a sensor sealing cover (1), a sealing cover connecting rod (2), an air cylinder (2) and a sensor probe (6), wherein the sensor sealing cover (1) is used for isolating a sensor from being polluted by dust in test; the sealing cover connecting rod (2) is connected with an air cylinder (4) and the sealing cover (1); the air cylinder (2) is a transmission mechanism of the sealing cover, exposes a sensor probe (6) to the environment in the box for measuring humidity when being opened and seals the sensor for avoiding pollution when being closed; and the sensor probe (6) is used for detecting the temperature and humidity in the box. The structure causes the dust used for the test and running for long time to remain dry, therefore, testers can easily control the use quantity of dust.
Description
Technical field
The utility model relates to a kind of environmental test chamber, relates in particular to have the environmental test chamber that has increased humidity measurement system.
Background technology
According to GB/T 2423.37-2006 electric and electronic product environmental test part 2: test method test L: be lower than 25% requirement among sand and dust test 4.1.4.5 and the 4.2.4.5 for humidity in the environmental cabinet, common dust-proof test case, because in process of the test, can produce the suspension environment of the superfine dust of big concentration, wet and dry bulb and two kinds of moisture measurement modes of capacitance type sensor commonly used all can't be avoided being adhered to by dust and damaging, so general dust-proof test case is not with the moisture measurement control system.
Reduce relative humidity in the experimental enviroment case, help the drying of dust, make dust settling more abundant, adhesive force is littler, and the equipment operation is more reliable, thus need to introduce humidity measurement system, and the device of protecting this measuring system.
The utility model content
In order to make in the dust-proof test case moisture measurement more accurate, sensor probe is not subjected to dust pollution, and sustainable running time is longer, this novel structure that a kind of effective seal sensor probe is provided
The dust-proof test case that has humidity measurement system of the present utility model, its measuring system comprises: the sensor seal closure, in order to the isolation sensor middle dust pollution that is not put to the test; The seal closure connecting rod connects cylinder and seal closure; Cylinder, the transmission mechanism of seal closure makes sensor be exposed to environment measurement humidity in the case during unlatching, make the sensor sealing not contaminated when closing; Sensor probe is used to survey humiture in the case.
Said structure has following outstanding advantage: in the common dust-proof test case, require the talcum powder of the superfine granularity of use according to GB, owing to receive the influence that water in air is divided, adhesive force can increase after use after a while, between the particle, have between particle and the cabinet wall obviously to adhere to and cause operating personnel to be difficult for judging the use amount of dust, thereby influence result of the test, this device has extremely effectively improved this shortcoming, by the heat drying before each test, effectively increased the dependability of equipment.
Be described further below with reference to the technique effect of accompanying drawing, to understand the utility model fully concrete structure of the present utility model and product dirt.
Description of drawings
Fig. 1 is the schematic diagram of dust-proof test case of the present utility model.
The specific embodiment
As shown in Figure 1, for having the dustproof environmental test chamber of humidity measurement system, this system comprises, seal closure 1, seal closure drive link 2, transmission cylinder 4, sensor probe 6, sensor body 5 and connecting line 7.
Chamber is before spray dirt begins, and electrical system makes cylinder 4 release seal closure 1 by connecting rod 2 by the control cylinder valve, the sensor probe 6 that is fixed on the chamber private side wall is exposed to reaches the purpose of measuring humiture in the chamber inner space.System rises the temperature inside the box by the thermofin that adds between cabinet wall face and the outside wall surface, relative humidity reduces, when sensor probe 6 detects relative humidity and reaches in the desired lower range, control system reclaims seal closure 1 by cylinder, the enhanced leaktightness effect make it firmly be adjacent to sidewall 3, for can install silastic sealing strip additional at the contact jaw of seal closure 1 and wall.Like this in spray dirt test, sensor probe 6 will be effectively and the interior sand and dust environment isolation of case, avoids being damaged.
Said structure has following outstanding advantages: in the common dustproof test box, require the talcum powder of the superfine granularity of use according to GB, because the impact of receiving moisture in air, adhesive force can increase after use after a while, between the particle, have between particle and the cabinet wall obviously to adhere to and cause operating personnel to be difficult for judging the use amount of dust, thereby affect result of the test, this device has extremely effectively improved this shortcoming, by the heat drying before each test, effectively increased the dependability of equipment.
