However, the pace of life is constantly accelerating now, and there is a demand for automatic switch water dispensers. Also there is a kind of automatic beverage vending machine in the prior art, can realize automatic switch, it exists the defective that must use disposable water cup, and only allows to use the cup of a kind of cup height.

Contents of the invention

The technical problem to be solved by the utility model is to provide an automatic switch water dispenser with simple and reasonable structure, which can realize the automatic switch of the water dispenser when there is no one, and can adapt to the use of cups with different cup heights.

The technical problem to be solved by the utility model is realized through the following technical solutions. The utility model is an automatic switch water dispenser, which includes a casing and an electric heater. A water receiving chamber is arranged on the casing, and a water discharge port is arranged above the water receiving chamber. The cup height detection laser head group composed of several cup height detection laser heads and the cup height detection photodiode group composed of several cup height detection photodiodes arranged horizontally and symmetrically on the body, the shell above the cup height detection laser head group The body is also equipped with a liquid level detection laser head inclined to the lower side of the water receiving chamber, and the housing above the cup height detection photodiode group is also provided with a number of liquid level detection photodiodes that are directed towards the water receiving chamber. The liquid level detection photodiode group inclined at the lower side of the chamber; it is also equipped with a solenoid valve, a single-chip microcomputer and a relay, the cup height detection laser head, the cup height detection photodiode, the liquid level detection laser head, the liquid level detection The photodiode and the relay are all connected with the single-chip microcomputer through the wire; the solenoid valve is connected with the relay through the wire, and the solenoid valve is arranged on the water discharge pipeline at the front end of the water discharge port.

The technical problems to be solved by the utility model can be further realized through the following technical solutions. The above-mentioned automatic switch water dispenser is characterized in that: the cup height detection laser head group is composed of 3-5 cup height detection laser heads evenly spaced, and the cup height detection photodiode group is also composed of 3 cup height detection laser heads. - Consists of 5 cup height detection photodiodes arranged at even intervals.

The technical problems to be solved by the utility model can be further realized through the following technical solutions. The above-mentioned automatic switch water dispenser is characterized in that: the liquid level detection photodiode group is composed of 2-3 liquid level detection photodiodes.

The utility model detects the height of the water cup and the liquid level by arranging laser heads and photodiodes on both sides of the water outlet.

When in use, the power of the water dispenser is turned on, the water cup is placed in the water receiving room below the water outlet, the cup height detection laser head is shielded, the cup height detection photodiode is triggered, and an electrical signal is generated, which is transmitted to the single-chip microcomputer, and the single-chip microcomputer controls the solenoid valve, and there is water. flow out. At the same time, the cup height detection laser head works, activates the symmetrically arranged cup height detection photodiodes, generates an electrical signal and transmits it to the single-chip microcomputer, and judges the height of the water cup. The single-chip microcomputer starts to work on this basis, and produces the highest water surface height of the water cup. The liquid flowing out of the water outlet gradually enters the water cup, and the water level gradually rises. The liquid level detection laser head emits laser light. After the laser is reflected by the liquid surface, it is triggered to the corresponding liquid level detection photodiode, which generates an electrical signal and transmits it to the microcontroller. Calculate the real-time liquid level height. When the liquid level reaches the maximum limit of the water cup, the single-chip microcomputer closes the solenoid valve, stops water discharge, and completes the entire water intake operation.

The utility model has the advantages of simple and reasonable structure, convenient and safe use, and can realize the water fetching operation under the condition of unattended, and the water fetching is not limited by the height of the water cup.
