The filter device includes at least two filter modules arranged in parallel, each having a water inlet and a water outlet. The water inlet is connected to a solenoid valve. A TDS probe is installed at the side interface of the three-way joint. A display panel and circuit board are mounted on the plastic sleeve. The TDS probe is connected to the circuit board via a wire and feeds back the detected water quality data to the circuit board. The circuit board controls the display panel to display the water quality data and controls the opening and closing of the solenoid valve.

The overall idea is as follows:

[0025] In response to the problems existing in the prior art, the utility model provides a faucet with a water quality detection function, including a faucet body 1, a detection tube 2 is fixedly installed on the faucet body 1, a stainless steel lifting frame 3 is slidably installed inside the detection tube 2, rubber pads 4 are symmetrically fixedly installed at both ends of the stainless steel lifting frame 3, a samarium cobalt permanent magnet 5 is fixedly installed on the top of the stainless steel lifting frame 3, and a spring 6 is fixedly installed inside the detection tube 2.

[0026] An electromagnet 8 is fixedly installed inside the faucet body 1, and a control box 9 is fixedly installed inside the faucet body 1; the faucet body 1 and the detection tube 2 are connected, the spring 6 is located at the bottom end of the stainless steel lifting frame 3, the samarium cobalt permanent magnet piece 5 corresponds to the electromagnet 8, the electromagnet 8 is connected to the control box 9 through a wire, and a TDS probe 7 is fixedly installed inside the detection tube 2; the TDS probe 7 is connected to the control box 9 through a wire, and a battery 11 is fixedly installed inside the faucet body 1.

[0027] The battery 11 is connected to the control box 9 via a wire, and a control panel 12 is fixedly installed on the top of the faucet body 1; the control panel 12 is connected to the control box 9 via a wire, a charging plate 15 is fixedly installed inside the faucet body 1, and a generator 13 is fixedly installed inside the faucet body 1; the generator 13 is connected to the charging plate 15 via a wire, and the charging plate 15 is connected to the control box 9 via a wire, and an impeller 14 is fixedly installed on the rotating shaft of the generator 13.

[0028] Working principle:

[0029] In the first step, the control box 9 is integrated with the STM32 control board, TDS-3 sensor and ESP32 wireless transmission module. The two TDS probes 7 are located on the side of the water outlet of the faucet body 1. In the initial state, the rubber pad 4 is pressed against the top of the detection tube 2 under the action of the elastic force of the spring 6, so that the inside of the detection tube 2 is isolated from the faucet body 1. When the valve is opened, the water will be discharged directly from the water outlet of the faucet body 1. When you want to test the water quality, send a signal to the control box 9 through the control panel 12, so that the control box 9 turns on the electromagnet 8. When the electromagnet 8 is energized, it will generate a magnetic force that repels the upper surface of the samarium cobalt permanent magnet 5. The electromagnet 8 will push the samarium cobalt permanent magnet 5 to slide downward, and the samarium cobalt permanent magnet 5 will push the stainless steel lifting frame 3 to slide downward to overcome the elastic force of the spring 6, so that the rubber pad 4 under the stainless steel lifting frame 3 will press against the bottom of the detection tube 2, sealing the opening at the bottom end of the detection tube 2. The upper rubber pad 4 will be separated from the top of the detection tube 2 in this process, so the water in the faucet body 1 will flow into the inside of the detection tube 2 along the top of the detection tube 2, and then the control box 9 will The water inside the test tube 2 is tested using two TDS probes 7, and the test results are displayed on the control screen 12. The control box 9 also transmits the test data to a mobile phone via the internal ESP32 wireless transmission module. The user can also control the device via the mobile phone. During the water quality testing process, the water flow out of the opening of the faucet body 1 is not affected. When the test is completed, the electromagnet 8 is de-energized. After the electromagnet 8 is de-energized, the stainless steel lifting frame 3 is reset under the elastic force of the spring 6. After the stainless steel lifting frame 3 is reset, the top of the test tube 2 is blocked by the upper rubber pad 4, preventing further water from entering. The lower rubber pad 4 will move away from the bottom of the test tube 2, opening the bottom of the test tube 2. The water inside the test tube 2 will be discharged through the opening at the bottom of the test tube 2. After the water inside the test tube 2 is discharged, the TDS probe 7 will no longer come into contact with the water. By turning the electromagnet 8 on and off, the stainless steel lifting frame 3 is allowed to slide up and down, controlling the contact between the TDS probe 7 and the water, thereby preventing the TDS probe 7 from rusting due to long-term exposure to a humid environment and affecting the water quality.

[0030] In the second step, when water flows inside the faucet body 1, it will drive the impeller 14 to rotate. The rotation of the impeller 14 will drive the shaft of the generator 13 to rotate, so that the generator 13 generates current. The current generated by the generator 13 will be transmitted to the charging plate 15 through the wire. The charging plate 15 will regulate and integrate the current generated by the generator 13, and then transmit it to the control panel 12 through the control box 9. The control panel 12 will store the current generated by the generator 13, and drive the impeller 14 to rotate through the water flow to complete the drive of the shaft of the generator 13, so that the equipment installation does not require additional wiring, achieving the effect of easy installation.

[0031] Finally, it should be noted that the above embodiments are merely examples for the purpose of clearly illustrating the present invention and are not intended to limit the embodiments. Those skilled in the art will readily appreciate that other variations or modifications based on the above description are possible. It is not necessary and impossible to enumerate all embodiments here. Obvious variations or modifications arising therefrom remain within the scope of protection of the present invention.
