Abstract

An anti-scalding water outlet device, including: a main body adapted to allow water to flow through; a control circuit board adapted to set a temperature parameter value; a temperature sensor, in connection with the control circuit board and adapted to sense water temperature inside the main body; and a solenoid valve, in connection with the control circuit board and adapted to use as a water flow switch of the main body, when the solenoid valve is opened to allow water to flow out of the main body, the control circuit board obtaining water temperature information transmitted from the temperature sensor; when the water temperature exceeds the set temperature parameter value, the control circuit board issuing a command to close the solenoid valve and stop waterflow of the main body, thereby preventing high temperature water from scalding users.

Therefore, the present invention is safe and practical.

Claims

1. An anti-scalding water outlet device, comprising:

a main body, adapted to allow water to flow through;

a control circuit board, adapted to set a temperature parameter value;

a temperature sensor, in connection with said control circuit board and adapted to sense water temperature inside said main body; and

a solenoid valve, in connection with said control circuit board and adapted to use as a water flow switch of said main body,

when said solenoid valve is opened to allow water to flow out of said main body, said control circuit board obtaining water temperature information transmitted from said temperature sensor;

when said water temperature exceeds said set temperature parameter value, said control circuit board issuing a command to close said solenoid valve and stop waterflow of said main body, thereby preventing high temperature water from scalding a user.

2. The device according to claim 1, wherein a seat is configured inside said main body, and said temperature sensor is pressed to fix to a concave portion of said seat by using a screw together with a washer.

3. The device according to claim 1, wherein a hot water pipe and cold water pipe are configured on a lower side of said main body, and a cold and hot water rod is configured on a lateral side of said main body, said hot and cold rod adapted to control a mixing ratio of hot water of said hot water pipe and cold water of said cold water pipe in a rotational manner.

4. The device according to claim 1, wherein said control circuit board is further in connection with a lamp, a first infrared sensor and a second infrared sensor.

5. The device according to claim 4, wherein said lamp is an LED lamp.

6. The device according to claim 4, wherein said control circuit board is configured in a protective cover first infrared sensor, said control circuit board, first infrared sensor and protective cover are configured on one side inside said main body, and said main body allows sensing light of said first infrared sensor to penetrate it to carry out sensing.

7. The device according to claim 4, wherein one end of said main body having an end cover having a plurality of through holes, said lamp, second infrared sensor are plurality of through holes and further on said end of said main body, and said plurality of through holes allows sensing light of said second infrared sensor to pass therethrough to carry out sensing, thereby allowing users to observe the illumination of said lamp.
