Tap switch assembly and infrared sensing tap

Abstract

The invention discloses a tap switch assembly comprising an infrared sensor, an electromagnetic valve and a control module. The infrared sensor senses a nearby object close to a tap, the electromagnetic valve is arranged on a water supply pipeline of the tap, and the control module is in communication connection with the infrared sensor. The control module controls the electromagnetic valve to be turned on when the distance of the object sensed by the infrared sensor is smaller than preset sensing distance, and controls the electromagnetic valve to be turned off when the infrared sensor does not senses the object within the preset sensing distance; the preset sensing distance is set by the means that starting timing from when the control module is switched from the power-off state to the power-on state, the distance of the object continuously sensed by the infrared sensor within a certain period of time serves as the preset sensing distance, and the preset sensing distance is removed till the control module returns to the power-off state again. The invention further discloses an infrared sensing tap provided with the tap switch assembly. The preset sensing distance can be set automatically, and the tap switch assembly and the infrared sensing tap are applicable to counter basins of different sizes and shapes.

Description

technical field [0001] The present invention relates to the field of automatic control, in particular to a faucet switch assembly, which can automatically adjust the sensing distance according to the different environments or different sizes of the table, and then control the opening and closing of the electromagnetic valve. Switch components for faucets. Background technique [0002] The infrared sensor faucets in the prior art mainly have the following two problems: [0003] First, the sensing distance of the faucet is fixed and cannot be adjusted, and the size of the basin is different. When encountering a shallower basin, the bottom of the basin will be mistaken for an effective sensing object, resulting in unusability or frequent malfunctions . [0004] Second, in the prior art, the infrared sensor is generally arranged in front of the faucet body and installed in a horizontal direction. At this time, the infrared rays emitted by the infrared sensor are perpendicular ...

[0003] First, the sensing distance of the faucet is fixed and cannot be adjusted, and the size of the basin is different. When encountering a shallower basin, the bottom of the basin will be mistaken for an effective sensing object, resulting in unusability or frequent malfunctions

[0004] Second, in the prior art, the infrared sensor is generally arranged in front of the faucet body and installed in a horizontal direction. At this time, the infrared rays emitted by the infrared sensor are perpendicular to the water flow direction of the spout, and it is easy to misjudge the water flowing from the spout. In order to effectively sense objects, it is easy to fail to close the water if the response of shutting off the water is slow or the water pressure is slightly higher.
