Example Embodiment

[0025] Example 1, such as figure 1 As shown, the smart metal-based infrared sensor faucet in this embodiment includes a faucet body 1, an infrared sensor 2 and a valve 3 for blocking or opening water pipes, an infrared sensor 2 and a valve. 3 is connected to the power supply module 4 through a wire, wherein the valve 3 is a smart metal valve made of nickel-titanium shape memory alloy, the power supply module 4 is equipped with a battery, and the power supply module 4 is provided with a power indicator 41 on the surface to indicate whether it is needed Replace the battery. The faucet body 1 is also provided with a heating element 5, the infrared sensor 2 is coupled to the heating element 5, and the heating element 5 is coupled to the smart metal valve 3, such as figure 2 As shown, the initial shape of the smart metal valve 3 when it is manufactured under high temperature conditions is a, and it reaches another shape b after plastic deformation at a certain low temperature, that ...

Example Embodiment

[0026] Embodiment 2. The difference between the technical solution of this embodiment and embodiment 1 is that the valve 3 in this embodiment is a smart metal valve made of iron-based shape memory alloy, which is different from the nickel titanium valve in embodiment 1. Compared with the shape memory alloy, it is cheaper and can reduce the production cost of the infrared sensor faucet.

[0027] Take the above two embodiments as examples to illustrate the working principle of the smart metal-based infrared sensor faucet of the present invention: when the faucet is not in use, the smart metal valve 3 is in a state of blocking the water pipe, and when the user needs to use the faucet, it is covered by hand Infrared sensor 2. At this time, the infrared light emitted by the infrared emitting tube in the infrared sensor 2 is reflected to the infrared receiving tube due to the cover of the hand, and the buzzer 42 emits a sound prompt, and then connects to the main circuit and conducts wi...

Abstract

The invention discloses an infrared induction faucet based on smart metal. The infrared induction faucet comprises a faucet body. The faucet body is provided with an infrared sensor and a valve for blocking or unblocking a water pipe. The infrared sensor and the valve are connected with a power supply module through a wire. The valve is a smart metal valve and made of a shape memory alloy. A heating element is arranged on the faucet body. The infrared sensor is coupled to the heating element. The heating element is coupled to the smart metal valve. The smart metal valve is in the state of blocking the water pipe under the normal temperature and is changed to the state of unblocking the water pipe when heated. A solenoid valve for a traditional infrared induction faucet is replaced with the smart metal valve for the infrared induction faucet, and the service life of the infrared induction faucet is prolonged.

Description

technical field [0001] The invention relates to the technical field of intelligent metal products, in particular to an infrared induction faucet based on intelligent metal. Background technique [0002] The existing infrared sensor faucet is based on the principle of infrared reflection. When the hand of the human body is placed in the infrared area of ​​the faucet, the infrared rays emitted by the infrared emitting tube in the infrared sensor are reflected to the infrared receiving tube due to the blocking of the human hand, and pass through the integrated circuit. The signal processed by the microcomputer inside is sent to the pulse solenoid valve. After the solenoid valve receives the signal, it opens the valve core according to the specified instruction to control the water from the faucet; when the human hand leaves the infrared sensing range, the solenoid valve does not receive the signal, and the solenoid valve core is The internal spring is used to reset to control t...
