What are the functions and characteristics of intelligent drinking fountains?

With the improvement of living standards, our requirements for household appliances are getting higher and higher. The emergence of drinking fountains and intelligent drinking fountains not only satisfies people's curiosity, but also brings great changes to our lives. Next, let's learn about the intelligent water dispenser.

What is an intelligent water dispenser?

One function of the intelligent water dispenser is humanized, that is, heat protection. When there is no water, the drinking water will give an alarm to remind us that the machine is in an overtemperature state and should be handled! Compared with traditional drinking fountains, the appearance of intelligent drinking fountains is much more critical. The key is the heating key, which can control whether the machine starts heating or stops heating, and then the water outlet key. Press this button to drain water automatically, so as not to accidentally burn yourself as before! There is also a lock key, and pressing its other keys will no longer work. This treatment provides a good platform for parents with children at home, and they no longer have to worry about whether their children will be scalded by the water dispenser! There is also a temperature setting key to provide people with all kinds of temperatures they want.

Don't worry about the waiting time because it is too cold or too hot! Functional characteristics of intelligent water dispenser

The new touch water dispenser reminds users to drink water.

This new type of drinking machine adopts wall-mounted structure design, which can be directly hung on the wall to reduce the floor space. There is a blue indicator light on the CD. Every time you drink a glass of water,

Just move one square clockwise. In operation, it is also very simple. In the middle of the disc is a touch-type water outlet device. You can fill a glass of water with a touch. At the same time, the LED display in the middle will show how many glasses of water have been received so far. Can control hot water or cold water.

More humanized, you can also adjust the temperature of the water temperature at any time. For example, touching to the left will produce hot water, and touching to the right will produce cold water, which meets the drinking water needs of different occasions. This new type of water dispenser looks strange, like an ornament, and it can also remind users to remember to drink water on time, which is very humanized. At present, the product is still in the testing stage, and there is still some time to go on the market.

Water dispenser type

So far, this kind of drinking machine is mainly divided into single type and compound type: the former is only responsible for the heating part, and it needs to directly introduce filtered pure water, and then realize "secondary heating" according to the set temperature; The latter has dual functions of filtering and heating, and can be applied to various types of water sources to realize the whole process of filtering first and then heating.

Generally speaking, the single-function instant heating water dispenser is small in size, the price is around 1,000 yuan, there is no additional use cost, and there is basically no need to install and debug, which is more suitable for families who have installed water dispensers that meet the filtering function.

As a "companion" of the existing composite water purification equipment; The invention is suitable for families without water purification system or for independent use indoors. Because of the functions of filtering and heating, there will be a certain use cost (similar to bottled water), and some of them also need certain technical support from manufacturers in installation and debugging. Circuit design of intelligent energy-saving water dispenser

The newly added components include typical capacitor buck circuits composed of Cl, C2, Rl, DW and D, which provide stable llV DC voltage for TX982 and 555 time base circuits. TX982 is a microwave induction controller, which contains a microprocessor and uses microwave Doppler effect to establish a micro-electric field in a certain space. When someone or a moving object enters the electric field, it will reflect the echo, and after being mixed by the electronic circuit, it will detect a very weak frequency shift signal. After the signal is intelligently processed,

A control signal can be output. The effective monitoring radius of TX982 is 1 ~ 7m. The reason why pyroelectric inductor is not used here is that it is convenient to refit. Pyroelectric inductor is particularly sensitive to heat source and easy to misoperate. As long as the microwave induction controller is installed behind the plastic panel of the water dispenser, it can be tested without damaging the appearance of the water dispenser. The output of TX982 adopts open collector output. When the microwave circuit detects that someone is moving in the monitoring range, the internal triode is turned on for 10 second, and the charge on C3 is discharged. 555 circuit constitutes a monostable delay circuit. When the second pin is lower than the power supply voltage 1/3, the third pin outputs a high level, the relay is turned on, and Kl turns on the heater for heating. The delay time of R2 and C3 is 3 minutes, and the delay time is set relatively short. If someone just passes by briefly, the drinking machine will automatically stop heating for 3 minutes. If there is someone in the room all the time, TX982 will trigger the monostable circuit to work many times within the delay time.
