The water level detecting means 50 may detect a high water level and a low water level, and when the water in the pure water cup 40 is the low water level, the water level detecting means 50 detects the low water level and issues a signal to control the clean water dispenser 100 to start making water. Pure water flows into the pure water cup 40 through the first connection port 210, and the water level in the pure water cup 40 starts to rise until reaching a high water level. At this time, the water level in the water level detecting means 50 rises, and after a high water level is detected, a signal is issued to control the water purifying dispenser 100 to stop water production.

In one embodiment, the water level detecting device 50 has a first water level near an upper end of the water level detecting device 50 and a second water level near a lower end of the water level detecting device 50; when the water level in the water level detection device 50 is lower than the second water level, the water purifying dispenser 100 starts to produce water; when the water level in the water level detecting means 50 is higher than the first water level, the water purifying dispenser 100 stops the water production.

The water level detecting device 50 has a first water level and a second water level, the first water level being near the upper end of the water level detecting device 50 for detecting a high water level; the second water level is near the lower end of the water level detecting means 50 for detecting a low water level. The water level monitoring device is communicated with the pure water cup 40 through the waterway channel, and the pure water cup 40 is basically consistent with the water level of the water level detection device 50 according to the principle of a communicating vessel. When the water level in the water level detecting means 50 is lower than the second water level, the water level in the pure water tank is also at a low water level, and the water level detecting means 50 sends a signal to control the clean water dispenser 100 to start making water. When the water level in the water level detecting means 50 is higher than the first water level, the water level in the pure water tank is also at a high water level, and the water level detecting means 50 sends a signal to control the pure water dispenser 100 to stop making water. The water level of the water level detecting device 50 reflects the water level in the pure water cup 40, and can control the automatic starting and closing of the pure water dispenser 100 according to the water level, so that the pure water cup 40 always has enough pure water for drinking.

When the water level in the pure water cup 40 is low, the float 540 in the balance pipe 530 approaches the second reed pipe 520, the second reed pipe 520 detects the float 540, and the purified water dispenser 100 starts to produce water. At the same time as the water level in the pure water cup 40 rises, the water level in the balance pipe 530 rises, and the float 540 rises with the water level in the balance pipe 530 until the float 540 approaches the first reed pipe 510. The first reed switch 510 detects the float 540 and the water purifier 100 stops making water.

Specifically, the float 540 moves up and down due to the rise and fall of the liquid surface in the balance pipe 530, and when the float 540 having magnetism moves to the position set by the first reed pipe 510 and to the position set by the second reed pipe 520, the normally open contacts in the first reed pipe 510 and the second reed pipe 520 are turned on by the magnetic field of the float 540. When the float 540 is moved away at the first and second water levels, the junction is released. Thus, the water level signal in the balance pipe 530 can be obtained according to the on/off state of the contact point of the first reed pipe 510 and the second reed pipe 520.

Reed switches, also known as reed switches, are electrical switches that are operated by an applied magnetic field. The reed switch is formed by sealing two magnetic reeds (usually composed of two metals of iron and nickel) in a glass tube. The two magnetic reeds are in an overlapped state but a small gap is arranged between the two magnetic reeds, and an external proper magnetic field can lead the two magnetic reeds to be contacted. The contacts on the two reeds are plated with a layer of very hard metal, typically rhodium and ruthenium, which greatly increases the life of the switching times. Nitrogen or some equal inert gases are usually injected into the glass tube, and the interior of the glass tube is made into a vacuum state in order to improve the switching voltage performance of the partial reed switch.

The reed acts as a magnetic flux conductor. When not operated, the two reeds are not contacted; when the magnetic field generated by the permanent magnet or the electromagnetic coil is applied, the magnetic field causes the two leaf springs to generate different polarities near the end points, and when the magnetic force exceeds the elasticity of the spring, the two leaf springs can attract and conduct a circuit; when the magnetic field is reduced or eliminated, the dry reed is released due to its elasticity, and the contact surfaces are separated to open the circuit.

Inert gas is sealed in the glass tube of the reed pipe, so that the reed is less affected by moisture and oxidation and is more reliable in contact; the volume is small, the cost is low, and the requirement on structural design is small; because the reed of the reed switch is very small, the switching-on and switching-off speed of the reed switch is faster and is generally 5-10 times faster than that of a relay. The magnetic field control switch can be applied to non-contact circuit control.
