The principle of G9 mini microswitch in water purifier

The principle of the G9 mini microswitch in the water purifier is similar to that of the G9 mini microswitch in other electronic devices. A G9 mini microswitch is an electronic switch that can trigger its on-off function with a small force or displacement. G9 mini microswitches usually consist of the following parts: contacts, spring blades, housing and drive rod (or button). The contact is responsible for switching on and off the circuit, the spring leaf plays the role of support and reset, the shell protects the internal structure and provides an installation interface, and the drive rod (or button) is the medium for the user to interact with the G9 mini microswitch.

When the drive lever (or button) is not acted upon by external force, the spring leaves remain in their original state, the contacts are in an open state, and the circuit is in an open state. When the user presses the actuation lever (or button), the actuation lever compresses the leaf spring and moves the contact. During this process, the contact state between the contacts will change, causing the movable contact and the fixed contact to contact, thereby closing the circuit, thereby energizing the circuit.

When the user releases the drive lever (or button), the spring leaf will generate a restoring force to return the contact to its original position, that is, the movable contact and the fixed contact are disconnected, the circuit is disconnected, and the power supply is stopped.

Microswitches can trigger actions with tiny forces or displacements, making them ideal for use in scenarios that require precise control. The G9 mini microswitch has a small contact spacing and a short action stroke, which can achieve fast on and off actions. The structure of the G9 mini microswitch is simple and stable, and has high reliability and durability. In water purifiers, G9 mini microswitches are usually used to control the opening and closing of water outlets, heating elements and other components, as well as to implement functions such as water level detection and filter element replacement prompts. Through precise control of G9 mini microswitches, the drinking machine can provide users with a safer and more convenient experience.

G9 Mini Microswitch

What is the function of the G9 mini microswitch in the water purifier?

The microswitches in the purifier have a variety of functions. The microswitches in the purifier play an important role in control functions, safety protection, intelligence and convenience, as well as energy conservation and environmental protection. They are one of the key components for the normal operation of the water purifier and the provision of quality service.

  1. G9 mini microswitchcontrol function

The G9 mini microswitch is used to control the water outlet of the water purifier. When the user needs to get water, he presses the water button (or operates other triggering devices). After receiving the signal, the G9 mini microswitch will trigger the circuit, thereby controlling the switch of the solenoid valve at the water outlet, so that water flows out from the water outlet. When the user stops taking water or reaches the set water volume, the G9 mini microswitch will trigger the circuit again, close the water outlet solenoid valve, and stop water dispensing.

For water purifiers with heating and cooling functions, G9 mini microswitches are also used to control the start and stop of these functions. When the user selects hot or cold water, the G9 mini microswitch will receive the corresponding signal and trigger the corresponding circuit to start the heating or cooling element. When the water temperature reaches the set value or the user stops taking water, the G9 mini microswitch will trigger the circuit again and turn off the heating or cooling element.

  1. Security protection

During the heating process of the water purifier, if there is no water in the water tank or the water level is too low, the G9 mini microswitch will detect this situation and immediately cut off the power supply to the heating element to avoid dry burning and protect the safety of the heating element and the user. When the temperature inside the drink machine exceeds the set safety range, the G9 mini microswitch will trigger the over-temperature protection circuit and cut off the relevant power supply to prevent the equipment from overheating and causing fires or other safety accidents.

  1. Intelligence and convenience

High-end water purifiers are equipped with an automatic water sensing function. Through the cooperation of G9 mini microswitches and other sensors, the water cup can be automatically sensed and water discharged. This design improves the convenience and intelligence of use. The G9 mini microswitch can also be combined with the intelligent control system of the water purifier to realize functions such as filter replacement reminders and water tank water shortage reminders. When the life of the filter element expires or the water tank is insufficient, the G9 mini microswitch will trigger the corresponding circuit, causing the device to send out a sound or light signal to remind the user to perform corresponding operations.

  1.  Energy saving and environmental protection

G9 mini microswitches can help the water purifier achieve energy-saving mode. For example, in standby mode, G9 mini microswitches can control some circuits to enter low-power mode or sleep mode to reduce energy consumption. When the user needs to use the water purifier, he or she can quickly wake up the device and enter working status by triggering the G9 mini microswitch. Through the precise control of the G9 mini microswitch, the water purifier can achieve precise metering and water output control to avoid the waste of water resources. For example, after setting the water volume, the G9 mini microswitch can accurately control the opening time of the water outlet to ensure that only the required amount of water flows out.

Application scenarios of G9 mini microswitches for water purifiers

The water purifier is a new type of water purification product that integrates water purification, drinking water, heating and other functions into one, meeting the multiple needs of household drinking water. The water purifier contains multiple circuits inside to implement different functions, such as water purification, heating, refrigeration, etc. G9 mini microswitches can be used to control the switches of these circuits to start and stop various functions. For example, when the user presses the heating button of the water purifier, the G9 mini microswitch will receive the signal and trigger the corresponding circuit, thereby activating the heating function.

The safety of users needs to be ensured during use of the purifier. G9 mini microswitches can be used to implement safety protection functions, such as automatically cutting off the circuit under abnormal conditions such as too low water level or too high water temperature to avoid safety accidents. This safety protection function is one of the very important application scenarios of G9 mini microswitches in drink purifiers. With the development of technology, drinking water machines are gradually realizing automated control. G9 mini microswitches can be used to implement automatic control functions, such as detecting water quality, water quantity and other parameters through sensors, and automatically adjusting the working status of the water purifier. This automated control function can improve the use efficiency and user experience of the purifier. G9 mini microswitches are widely used in drink purifiers and are important. They can not only realize various functions of the drink purifier, but also ensure user safety and provide a better user experience.

What other application scenarios are there for G9 mini microswitches in drink purifiers?

In addition to the above-mentioned application scenarios such as control circuit, safety protection and automatic control, the microswitch in the water purifier also has the following specific application scenarios:

  1. Water outlet control: Drinking water machines are usually equipped with a water outlet to provide clean drinking water to users. The G9 mini microswitchcan be used to control the opening and closing of the water outlet to ensure that the water outlet can discharge water normally when the user needs it, and to close the water outlet when it is not needed to avoid the waste of water resources.
  2. Tips for replacing the filter element: After the water purifier is used for a period of time, the filter element will gradually become saturated and lose its filtering effect. The G9 mini microswitchcan cooperate with the life detection system of the filter element. When the filter element needs to be replaced, the G9 mini microswitchtriggers the corresponding prompt function, such as sound, light, etc., to remind the user to replace the filter element in time.
  3. Water tank water level detection: Drinking water machines usually have water tanks for storing water sources. The G9 mini microswitchcan be used to detect the water level in the water tank. When the water level is too low, the G9 mini microswitchtriggers the corresponding prompt or automatically stops the water supply function to prevent the water purifier from running without water.
  4. Door cover detection: Some water purifiers are designed with removable door covers to facilitate user cleaning and maintenance. The G9 mini microswitchcan be used to detect the opening and closing status of the door cover to ensure that the drink machine will not start or continue to run when the door cover is not closed or installed correctly to protect the safety of the user.
  5. Temperature control: For water purifiers with heating functions, G9 mini microswitches can be used to control the switching of the heating element to ensure that the water temperature is within the set range. When the water temperature reaches the set value, the G9 mini microswitchcan automatically cut off the power supply to the heating element to avoid burns or other safety issues caused by excessive water temperature.

These application scenarios make the G9 mini microswitch play a vital role in the drink purifier, improving the safety and convenience of use of the drink purifier.
