[0034] In one embodiment, the surface of the conveniently disassembled installation column 301 is movably embedded in the inner cavity of the water outlet groove 107, the inner movably sleeves of the three installation auxiliary grooves 302 are arranged on the surfaces of the three installation auxiliary blocks 110, and the surface of the sealing rubber ring 305 is tightly attached to the bottom of the annular sealing baffle 108.

[0035] Specifically: the sealing rubber ring 305 is tightly attached to the bottom of the annular sealing baffle 108 and the inside of the spring 204, thereby achieving a seal between the convenient disassembly installation column 301 and the annular sealing baffle 108, and preventing water from flowing out from the gap between the bottom of the annular sealing baffle 108 and the top of the convenient disassembly installation column 301 when water is discharged.

[0036] Working principle: the control terminal 103 is internally installed with a battery and a pulse solenoid valve, and the two hot and cold water inlet pipes 105 are connected to the heating and cold water pipes respectively.

The induction window device 101 is a prior art, and an infrared transmitting tube and an infrared receiving tube are installed inside it. The infrared rays emitted by the infrared transmitting tube are reflected to the infrared receiving tube due to the obstruction of human hands, and the signal processed by the microcomputer in the control terminal 103 is sent to the pulse solenoid valve, thereby controlling the water outlet of this faucet. When the human hand leaves the infrared sensing range, the solenoid valve does not receive the signal, and the solenoid valve core is reset by the internal spring to control the water shut-off of the faucet to realize automatic water outlet; by pulling down the convenient disassembly mounting column 301 with force The convenient disassembly installation column 301 moves downward in the inner cavity of the water outlet trough 107. During the downward movement of the convenient disassembly installation column 301, the arc-shaped limiting groove 303 squeezes the hemispherical limiting block 203, so that the hemispherical limiting block 203 drives the T-shaped moving column 202 to move toward the inner side of the inward T-shaped limiting column 201. At the same time, the spring 204 is deformed by the force until the arc-shaped limiting groove 303 is separated from the hemispherical limiting block 203. After the hemispherical limiting block 203 is no longer limited by the convenient disassembly installation column 301, the spring 204 returns to its original position under the elastic force of the spring 204. After the nozzle assembly 3 is taken out, it is inverted and the filter plate 307 is pressed downward. The filter plate 307 can be taken out from the bottom of the inverted convenient disassembly installation column 301. The reverse operation can be performed during installation. This design is convenient for quick installation and disassembly of the nozzle assembly 3. At the same time, the filter plate 307 is not a fixed design, which is convenient for taking out the filter plate 307 and cleaning the water alkali on the surface of the filter plate 307.
