Benefits of technology

[0007]An inductive faucet that may adjust a detection range according to this invention is provided, in which a faucet body is mainly arranged on a washbasin provided with a trough. A water outlet is formed at the top of faucet body and a PCB is arranged around the water outlet. On the PCB, two transmitter units, one receiver unit, and a controller unit are provided. Thus, the controller unit may control the transmitter units to transmit a signal toward the bottom side of washbasin, and detect the strength of signal reflected from the bottom side of trough through the receiver unit. When the signal strength is lower than the default, the setting of transmitter unit is kept and thus the standby mode enters; con

Example

[0019]Now, the present invention will be described more specifically with reference to the following embodiments. It is to be noted that the following descriptions of preferred embodiments of this invention are presented herein for purpose of illustration and description only; it is not intended to be exhaustive or to be limited to the precise form disclosed.

[0020]With reference to FIGS. 3 and 4 as a perspective view of an inductive faucet 100 in preferred embodiment of the present invention, and a front view of a PCB 30, the inductive faucet 100 is essentially provided with a faucet body 10. The faucet body 10 is fixed onto a washbasin 20 provided with a trough 21. A water outlet 11 is formed at the top of faucet body 10 and the PCB 30 is arranged near the water outlet 11. With cross-reference to FIG. 4, two transmitter units 31, one receiver unit 32, an alarm 33, and a controller unit 34 are provided on the PCB 30.

[0021]The transmitter units 31 are infrared transmitters and arrang...

Abstract

An inductive faucet of which a detection range is adjustable is provided, in which two transmitter units, one receiver unit, and one controller unit are arranged on a faucet body. The controller unit is used to automatically adjust the strength of signal transmitted by the transmitter unit for obtaining a preferable detection range; thus, the incorrect judgment rate may decrease significantly and further power waste caused by the extremely long detection range may be avoided. Particularly, regarding the inductive faucet provided with a battery used as a power source, the battery life may even be prolonged and the frequency of battery replacement may decrease.

Description

BACKGROUND OF THE INVENTION[0001]1. Field of the Invention[0002]This invention relates to an inductive faucet of which a detection range is adjustable.[0003]2. Description of the Prior Art[0004]With reference to FIG. 1 illustrating a conventional inductive faucet, a faucet body 3 is fixed onto a washbasin 1 of a trough 2. A water outlet 4 is formed at the top of faucet body 3. At the bottom of faucet body 3, an infrared inductive device 5 is provided facing toward the front of washbasin 1. The inductive device 5 continuously transmits a horizontal signal toward the front of washbasin 1, and the transmit power of inductive device 5 is controlled, thus making the detection ranger to be larger than the path along which the faucet body 3 yields water and to be smaller than the front edge of trough 2. Thus, when a user's hand is close to the faucet body 3, a signal reflects. At this time, the inductive device 5 receives the reflecting signal to turn ON a water supply switch and the water...
