[0043] The working principle of this utility model:

[0044] In the utility model, the reed switch is a passive electronic switch element with contacts, also known as a magnetic reed switch. It is usually composed of glass, two iron elastic reed electrodes and inert gas. When a magnetic substance approaches the reed switch, the two reeds will be magnetized and attract each other, so that the circuit is turned on; when the magnetic substance is removed, the reed loses its magnetism and returns to the disconnected state under the action of its own elasticity.

[0045] In the utility model, the Hall switch has a Hall element inside. When current passes through the Hall element and there is a magnetic field, the Hall element will generate a Hall voltage, and the on-off control of the switch is realized by detecting the change of the Hall voltage. The Hall effect principle is adopted, and the magnetic induction switch uses the electromagnetic induction principle. The sensitivity of the Hall switch is relatively high. The magnetic sensor made based on the Hall effect can detect the magnetic field and its changes, and convert it into an electrical signal output.

[0046] In the present invention, when water flows in from the water inlet, the water pressure pushes the magnet assembly upward, and the annular magnet 5 moves upward along the guide column 14 and approaches the circuit board 2. The dry yellow tube 10 or the Hall switch on the circuit board 2 receives a signal and sends a signal to the digital display screen 7 and / or the atmosphere light 8. The digital display screen 7 displays the real-time water temperature or lights up the atmosphere light 8. When the water stops flowing, the magnet assembly moves away from the circuit board 2 through the reset spring 18 and resets to the original position. At this time, there is no signal from the dry yellow tube 3 or the Hall switch, and the digital display screen 7 and the atmosphere light 8 are turned off.

[0047] In this embodiment, the design of the circuit board 2 can be based on whether it is used for the digital display screen 7, the atmosphere light 8, or a combination of the two. Ordinary circuit design is a conventional design of the technology in this field and is not the focus of the improvement of the utility model, so it will not be repeated here.

[0048] Although the embodiments of the present invention have been shown and described, it will be apparent to those skilled in the art that various changes, modifications, substitutions and variations of these embodiments without departing from the principles and spirit of the present invention should all be considered to fall within the scope of protection of the present invention.
