Abstract
The invention relates to the field of product reliability environmental tests and especially relates to the waterproof test of IPX4 and IPX5 protection grades on electronic and electrical products. The device comprises a nozzle, a mobile baffle plate, a balance weight, an attachment pin, an exhaust valve, a handle, a water supply hose, a pressure gage, a water purifying and filtering unit, a regulating valve, an air pump, an air pipe and a test sample. According to the technical scheme of the invention, whether the mobile baffle plate needs to be removed or not can be determined according to test requirements. After that, the device is connected with a water source, and the quality of the water is filtered by the water purifying and filtering unit. The water pressure is controlled by the regulating valve. In this way, when the test requirements are met, the test sample can be tested. After the test, the air pump is turned on, and the water in the nozzle is evacuated completely under the effect of the air pressure. Therefore, the nozzle obstruction problem due to long-term hydrops can be avoided. The device is movable and convenient to use, thereby greatly satisfying the requirements of the waterproof test on outdoor products. The defect in the prior art that traditional test equipment can only be used in test rooms can be overcome. Meanwhile, the device is composed of a simple water purifying unit and an air-pressure drainage system. As a result, the nozzle obstruction problem is effectively solved. The device is time-saving, easy to use and good in market application prospect.
Description
Technical field
The present invention relates to product reliability environmental test field, particularly relate to IPX4 and the IPX5 two kinds of degree of protection tests in the waterproof test of electron and electrician product.
Background technology
Electron and electrician product needed possesses water-proof function, the electron and electrician product of especially outwork, and water-proof function must possess, and the electrical safety performance of product so just can be made to be guaranteed, the safety of the available protecting person and public property.The waterproof test of product can be carried out in physical environment, and its advantage is that environmental baseline is true and reliable, but by the restriction of the factors such as region, time, weather, the reproducibility of test, rainfall amount number all can not control, be difficult to the test effect realizing expection.
When traditional waterproof test equipment carries out waterproof test, all parts of shell of some product can not all be drenched, and do not reach the test effect of expection.
Traditional waterproof test equipment, due to the water quality difference in each area, often can block shower nozzle; when especially outdoor products being tested, need to connect interim water source, the words that water quality is too poor; often can block shower nozzle, just effectively can not ensure the accuracy of discharge, have a strong impact on test effect.
Traditional waterproof test equipment can not carry out IPX4 and IPX5 two kinds of degree of protection tests simultaneously.
Traditional waterproof test equipment, generally can not move, and can only be confined to carry out in testing laboratory, to some be arranged on steady job place by trial product, traditional waterproof test equipment, owing to not moving, can not meet testing requirements.
Summary of the invention
The present invention is directed to the deficiency of conventional waterproof testing equipment, provide a kind of structure simple, moveable hand-held waterproof test device.
The present invention is achieved by the following technical solutions:
The present invention is made up of shower nozzle, balance device, water system, Pneumatic drainage system, the spherical that described shower nozzle is radius is 75.5mm, central angle is 78 degree, and spray heads is furnished with 121 holes, hole internal diameter is 0.5mm, wherein, interposition is equipped with 1 hole, and stretching out from the hole in centre position has 6 circles, the inside 2 circle, wherein often enclose each 12 holes, 12 holes are circumferentially being evenly distributed, and outside 4 is enclosed, wherein often enclose each 24 holes, 24 holes are circumferentially being evenly distributed.
Described balance device is made up of moving stop, balance bob, attachment pegs, and moving stop is connected with balance bob by attachment pegs, according to the requirement of test, determines whether to retain moving stop.
Described water system is made up of handle, water supply hose, filter for purifying water, tensimeter, variable valve, one end of water supply hose connects with handle, the other end connects with tensimeter, manometric other one end connects with filter for purifying water, and other one end of filter for purifying water connects with variable valve.
Described Pneumatic drainage system is made up of drain tap, tracheae, air pump, and during work, one end of tracheae connects with drain tap, and the other end of tracheae connects with air pump.
Accompanying drawing explanation
Accompanying drawing 1 is structural representation of the present invention.
Accompanying drawing 2 is shower nozzle front views.
Accompanying drawing 3 is shower nozzle lateral plans.
Wherein, 1 shower nozzle, 2 moving stops, 3 balance bobs, 4 attachment pegs, 5 drain taps, 6, handle, 7 water supply hoses, 8 tensimeters, 9 filter for purifying water, 10 control valves, 11 air pumps, 12 tracheaes, 13 test specimens.
Embodiment
With reference to accompanying drawing 1, the present invention is by shower nozzle 1, moving stop 2, balance bob 3, attachment pegs 4, drain tap 5, handle 6, water supply hose 7, tensimeter 8, filter for purifying water 9, control valve 10, air pump 11, tracheae 12, test specimen 13.During use, first according to testing requirements, determine whether to need to remove moving stop 2, when carrying out IPX4 test, moving stop 2 should be installed, balance bob 3 is depressed into the end, then tight joint pin 4, by locked for moving stop 2, then open control valve 10 and connect water source, start filter for purifying water 9 simultaneously, then hydraulic pressure is regulated by control valve 10, make the reading of tensimeter 8 reach testing requirements, then hold handle 6, alignment test sample 13 carries out waterproof test.After test, close control valve 10, tracheae 12 and drain tap 5 are connected, booster air pump 11, utilizes air pressure to be drained only by water remaining in shower nozzle 1, prevents because ponding overlong time causes shower nozzle 1 to block, after water in emptying shower nozzle 1, close air pump 11, disconnect drain tap 5 and tracheae 12 simultaneously.
When carrying out IPX5 test, attachment pegs 4 should be unclamped, moving stop 2 is extractd, then open control valve 10 and connect water source, start filter for purifying water 9 simultaneously, then regulate hydraulic pressure by control valve 10, make the reading of tensimeter 8 reach testing requirements, then hold handle 6, alignment test sample 13 carries out waterproof test.After test, close control valve 10, tracheae 12 and drain tap 5 are connected, booster air pump 11, utilizes air pressure to be drained only by water remaining in shower nozzle 1, prevents because ponding overlong time causes shower nozzle 1 to block, after water in emptying shower nozzle 1, close air pump 11, disconnect drain tap 5 and tracheae 12 simultaneously.The present invention is removable, easy to use, greatly meets the waterproof test requirement of outdoor products, overcome the drawback that traditional experiment equipment can only be confined in testing laboratory, and with simple water purification device and Pneumatic drainage system, efficiently solve shower nozzle blockage problem, save time handy.This invention has good market application foreground.
