Problems solved by technology

However, in order to increase the sensing range of infrared radiation, manufacturers relatively shorten the sensing distance and sacrifice the illuminance of the light when strengthening the light emitting angle of the LED. This situation makes the infrared energy too weak to be effectively detected by the infrared receiver. reception, thereby weakening the sensing effect, therefore, additional signal amplifier circuits are required to amplify the infrared signals received by the infrared receiver, but this will increase the manufacturing cost

Abstract

The invention is applicable to the field of bathroom equipment and discloses an infrared ray induction device and an inductive faucet comprising the same. The infrared ray induction device comprises a first light emitting module, a second light emitting module and a light receiving module. The first light emitting module comprises a first light emitter and a first lens with positive refractive power. The first light emitter emits infrared rays with a first optical axis through the first lens. The second light emitting module comprises a second light emitter and a second lens with positive refractive power. The second light emitter emits infrared rays with a second optical axis through the second lens. The light receiving module is located between the first light emitting module and the second light emitting module. The included angle between the first optical axis and the second optical axis in the emitting direction is an acute angle. The inductive faucet comprises the infrared ray induction device. According to the infrared ray induction device and the inductive faucet comprising the same, the induction range of the infrared ray induction device is large, and the inductive faucet is low in production cost, small in size and sensitive in control.

Description

technical field [0001] The invention belongs to the field of bathroom equipment, and in particular relates to an infrared induction device and an induction faucet thereof. Background technique [0002] Non-contact infrared sensor faucets, compared with the traditional faucets that need to be manually turned directly to control the water outlet valve, in addition to being hygienic, convenient, avoiding exposure and the threat of infectious diseases through contact, so in many public places, such as : Infrared sensor faucets are widely used in restaurants, hospitals, public toilets, etc. [0003] The known infrared sensing device used with the faucet is composed of an infrared emitter and an infrared receiver. Infrared rays are emitted through the infrared transmitter to generate an infrared irradiation range. When the user's hand enters the infrared irradiation range, the infrared rays will be reflected due to being blocked, and the reflected infrared rays will be received b...
