Water boiler capable of detecting water quality

Abstract

The invention relates to a circuit board capable of detecting water quality and belongs to the field of water boilers. The circuit board capable of detecting the water quality comprises a single-chipmicrocomputer comprising a CPS module (a capacitor touch sensing module) and a water quality detection interface. The single-chip microcomputer is connected with the water quality detection interfacethrough a pin RA4 and a pin GND. The water quality detection interface is connected with a water quality detection probe. The water quality detection probe makes contact with liquid to be detected tocarry out detection. The CPS module of the single-chip microcomputer detects data acquired by the water quality detection probe. The water quality detection probe is an electrode which can emit and receive capacitor signals at the same time. According to the circuit board capable of detecting the water quality, the single-chip microcomputer adopts the CPS module to detect the water quality, original components for water quality detection are omitted, the cost is reduced, the possibility of component damage is reduced, the stability of a water boiler is improved, the circuit board is suitable for all water boilers, the using voltage is 220 v-380 v, the size of the circuit board and software are standard, and a computer networking system needs to conform with a protocol modbus485, and integrated networked work is achieved.

Description

technical field [0001] The invention relates to a water boiler, in particular to a water boiler capable of detecting water quality equipped with a circuit board capable of detecting water quality. Background technique [0002] With the improvement of people's quality of life, people also attach great importance to the safety of drinking water, and drinking all raw water without treatment will bring great harm to people's health, so the country attaches great importance to drinking water safety , so water dispenser companies contribute to the safety of drinking water for people. However, the all-encompassing water boilers on the market have caused people a headache, because some companies and schools need to use high-end products, and the requirements for water quality testing are also very strict. Existing water boiler water quality detection relies on a lot of hardware equipment to detect water quality, the detection accuracy is poor, and each hardware equipment is easily d...

[0002] With the improvement of people's quality of life, people also attach great importance to the safety of drinking water, and drinking all raw water without treatment will bring great harm to people's health, so the country attaches great importance to drinking water safety Therefore, water dispenser companies contribute to the safety of drinking water for people. However, the all-encompassing water boilers on the market cause people a headache, because some companies and schools need to use high-end products, and the requirements for water quality testing are also very strict. Existing water boiler water quality detection relies on a lot of hardware equipment to detect water quality, the detection accuracy is poor, and each hardware equipment is easily damaged, which reduces the stability of the machine and increases the cost

[0003] The maintenance cost of high-end water boilers is extremely high. The circuit boards of each water boiler have poor adaptability, and the size of the circuit boards is not standard. If the circuit board is damaged and a machine is broken, the maintenance personnel of the original factory must come to the door for repairs. The maintenance service price of general door-to-door service far exceeds the maintenance price of the machine itself, and the singleness of the circuit board is the culprit for the high maintenance price, and it is also very difficult for some large-scale enterprises to realize networked water management, resulting in Waste of water and electricity resources
