[0017] Traditional water purifiers are locally controlled and operated, and the operating status and detection status are integrated on the water purifier body, which is not suitable for industrial automation control. The electrolysis water hydrogen production equipment requires that the TDS (Total Dissolved Solids) of the water used for hydrogen production should reach a very low value, and requires that the water used for hydrogen production should start or stop water production at any time according to the needs of the hydrogen production system. The traditional water purifier is a primary reverse osmosis treatment. In places where the water quality of the inlet water source is poor, the salt content of the treated pure water is still very high, which does not meet the requirements of precision equipment for water purity; the traditional water purifier has a single installation method and a large size, which is not convenient to integrate into the automatic control system, especially when installed in the AEM electrolysis water hydrogen production equipment. Therefore, it is a problem worthy of attention to achieve flexible controllability, small size, easy installation and maintenance, and lower TDS value of the water purifier.
[0018] Based on this, the utility model provides a water supply device and an electrolytic water production system. Based on the water supply device, the controllability of pure water production can be achieved. In addition, the water supply device is small in size, easy to install and maintain, and can achieve water supply with a lower TDS value.

[0020] The management module is used to receive a water inlet instruction, and control the water inlet control switch to be turned on according to the water inlet instruction, so that the filtration module receives the water to be treated and uses the filter element to filter the water to be treated; the reverse osmosis module is connected to the water outlet end of the filtration module, and is used to receive the filtered water and desalinate the filtered water; the water quality analyzer is used to detect the desalinated water and obtain the detection result; the communication unit is electrically connected to the water quality analyzer, and is used to obtain the detection result and send the detection result to the water-using equipment; the processing unit is electrically connected to the water outlet control switch, and is used to receive the water use instruction of the water-using equipment, and control the water outlet control switch to be turned on according to the water use instruction, so as to supply the detected water to the water-using equipment; wherein the water use instruction is obtained based on the detection result.
[0021] It should be noted that the water-using equipment may include, but is not limited to: equipment for producing hydrogen by electrolysis of water or equipment for producing oxygen by electrolysis of water. The type of water-using equipment can be determined based on actual needs, and the embodiments of the present utility model do not specifically limit this.
[0022] In an embodiment of the utility model, the management module can be electrically connected to the actuator in the water supply device to control the action of the actuator. The actuator included in the filter module includes a water inlet control switch, and the water inlet control switch is electrically connected to the management module. The management module can receive a water inlet instruction sent by a user, and the water inlet instruction is used to provide treated water for the water supply device. After receiving the water inlet instruction, the management module controls the water inlet control switch to open according to the water inlet instruction, so that the filter module receives the treated water and uses the filter element to filter the treated water. The treated water can be tap water. The input end of the filter module is connected to the tap water inlet, and the tap water is initially filtered. It should be noted that in order to optimize the filtering effect, multiple filter modules can be set.
[0023] In the embodiment of the utility model, the reverse osmosis module is connected to the water outlet of the filter module to receive the filtered water and perform desalination treatment on the filtered water. The reverse osmosis module uses reverse osmosis technology to remove most of the impurities such as dissolved salts, organic matter, microorganisms, bacteria and viruses in the water, thereby re-filtering the water after primary filtration to obtain high-quality pure water.
[0024] The water quality detection module includes a water quality analyzer and a communication unit, wherein the water quality analyzer is used to detect and measure various chemical components, physical properties and microbial content in the water body. In the embodiment of the utility model, the water quality analyzer is used to detect the desalinated water and obtain the detection result. The content included in the detection result is determined based on the type of water quality analyzer used. The type of water quality analyzer can be determined according to the specific needs of the water-using equipment, so as to obtain water that meets the detection requirements.

The TDS probe is usually composed of a sensor element, which can sense the ion activity in the solution when it contacts the water sample and convert it into an electrical signal. There is a certain correlation between this electrical signal and the total dissolved solids concentration in the solution. Using the TDS probe as a water quality analysis instrument, water with a TDS value that meets the requirements of water equipment can be obtained.

When the water in the current treatment state is available, the water-using equipment can generate a water use instruction and send it to the processing unit. The processing unit is connected to the water-using equipment in communication. For example, the water-using equipment can be an AEM water electrolysis hydrogen production system. The output signal of the water quality detection module is connected to the controller of the AEM water electrolysis hydrogen production system and participates in the overall control of the AEM water electrolysis hydrogen production system.

[0028] It should be noted that the water use instruction may include starting water use or stopping water use. When the water use instruction is to start water use, the processing unit is used to control the water outlet control switch to open according to the water use instruction to supply the detected water to the water-using equipment. When the water use instruction is to stop water use, the processing unit can also be used to control the water outlet control switch to close according to the water use instruction to stop supplying the detected water to the water-using equipment, thereby realizing starting or stopping water supply at any time according to the needs of the water-using equipment, thereby realizing the controllability of water supply.
