Description

A touch pull faucet

technical field

The utility model relates to the field of sanitary ware, in particular to a touch-type pull faucet.

Background technique

Basin faucets and kitchen faucets with traditional mechanical opening methods cannot be turned off when there is debris or dirt on the hand during use, resulting in the faucet being always on, which is a serious waste of water resources. If the handle switch is forcibly turned off, it will also Dirt is left on the handle, making it difficult to maintain and clean the faucet, and reducing the appearance life of the faucet;

For traditional pull-out faucets, the pull-out hose has no independent pull-out channel, and the pull-out hose is likely to interfere with other parts, thus affecting the pull-out use of the product. Moreover, the traditional faucet has no light prompt function when it is turned on or off, and the product appearance is relatively simple and does not have much artistic beauty.

The bottom of the product and the sink are not completely insulated, which is likely to interfere with the touch signal. Touching the sink table during use will also turn on the touch switch, resulting in customers being unable to use it normally.

After the error signal is processed, it will not output instructions to the solenoid valve switch circuit, so the touch function is invalid.

Low-battery and no-battery protection functions. In normal use, the handle 25 is turned on, and the touch function is turned on. When the battery power is lower than the preset threshold (lower than 4.5V), the monitoring voltage output by the power supply circuit 13 is transmitted to The main control circuit 14, the main control circuit 14 issues instructions to the solenoid valve switch circuit 16, so that the solenoid valve is always in the open state. At this time, the touch function fails, and the faucet returns to the traditional mechanical switch mode. When the battery is replaced, the touch function is restored. Use, to avoid the disadvantages of not being able to use the tap when the battery is low.

Anti-mistouch protection function. In normal use, the handle 25 is in the open state, and the touch function is also in the normal open state. When an accidental touch occurs (such as a pet or a mouse, etc.), the faucet will normally discharge water, and no one will operate it for ten minutes after the water is discharged. At this time, the main control circuit 14 sends a closing signal to the solenoid valve switching circuit 16, and the solenoid valve is closed; Prevent waste of water resources.
