Automatic weighing device for water purification amount of water purification machine, and using method of automatic weighing device

Abstract

The invention discloses an automatic weighing device for the water purification amount of a drinking water purification machine. The automatic weighing device comprises the parts of a water purification machine sample, a high-precision electronic scale I, a high-precision electronic scale II, a container barrel I, a container barrel II, an electronic control three-way valve, a water distribution system, a water reservoir, a circulating water pump, a PLC and the like. According to the automatic weighing device, a water container does not need to be replaced manually, thus the labor intensity isreduced, detection automation is achieved, and the detecting quality and efficiency are improved; and in addition, through a weighing method, the cumulative sum of multiple weighing serves as the total water purification amount, the water purification weight difference between the container barrels each time is extremely small, thus the total cumulative error is also small, the testing result ismore accurate, the detecting quality is improved, and the detecting dispute is avoided.

Description

technical field [0001] The invention relates to the technical field of product testing, in particular to an automatic weighing device for water purification of a water purifier and a use method thereof. Background technique [0002] As people pay more and more attention to the health of drinking water, household water purification equipment has entered thousands of households, and consumers and relevant state departments are paying more and more attention to the quality of water purifiers. [0003] Meters and flowmeters are usually used by testing agencies to test the water purification capacity of drinking water purifiers. Due to the long test time, many changing factors, and various cumulative errors in the pipelines and instruments used. In addition, the containers containing clean water need to be replaced manually, which is labor-intensive, resulting in low quality and efficiency of testing, and frequent detection disputes. There is no device and method for testing the ...
