Control method of water faucet

Abstract

The invention discloses a control method of a water faucet. The water faucet is characterized in that a first sensor used for sensing the hands of a user in the vertical direction is arranged on the water faucet. The control method of the water faucet comprises the following steps: S1, mixing clear water with a liquid soap according to a preset proportion to form a mixed hand-washing solution; S2, when the first sensor senses the hands of the user, controlling the water faucet to enable the mixed hand-washing solution to flow out, so that the water faucet enters a mixed hand-washing solution mode; S3, when the hands of the user is within the sensing range of the first sensor and after the mixed hand-washing solution flows out for a first preset time, controlling the water faucet to enable clear water to flow out, and the water faucet enters a clear water mode. The control method of the water faucet provided by the invention has the benefits as follows: when the user puts the hands under the water faucet, the liquid soap and the clear water which are mixed according to a proper proportion are discharged through the water faucet, and after the user scrubs with the mixed hand-washing solution, clear water is discharged automatically through the water faucet to thoroughly clean the hands of the user, the overall process is carried out in a same hand basin, no switch is needed, and therefore the use is simple and convenient.

Description

technical field [0001] The invention relates to the field of faucets, in particular to a method for controlling the faucets. Background technique [0002] The survey found that the handwashing habits of most respondents were not hygienic, and they seldom used hand sanitizer even in public restrooms. However, there are a lot of bacteria in public toilets. If you do not use hand sanitizer to wash your hands, a large number of bacteria will be left on your hands, causing the bacteria to spread widely and greatly affecting public health. However, the traditional automatic hand sanitizer has a chance to pollute the surrounding environment due to the delay of the sensor time or the user's misalignment. As a result, the cleaners waste more time cleaning, which is not conducive to the further promotion of the product. [0003] At present, the sensor of most automatic faucets is placed on the neck of the faucet to sense the hands in a horizontal direction, but this sensing method is...
