Description

Self-priming soap liquid feeding device

Technical field

The invention relates to a soap liquid supply device faucet, in particular to a self-priming soap liquid supply device capable of utilizing water pressure self-priming soap liquid.

Background technique

Current soap dispensers, the most common ones are mechanical one-press soap dispensers. It is simple to manufacture, low in cost, safe and reliable, and is currently the most commonly used. With the improvement of people's living standards and the demand for quality of life, people are increasingly inclined to automate, especially in public places. The automatic induction soap dispenser/automatic induction soap mixer has also emerged. The automatic induction soap dispenser is to set the soap liquid high, and the soap is released by the free fall of the soap by controlling the opening and closing of the bottom valve by the motor. However, this automatic induction to the soap dispenser when the soap liquid is just full, the sensor will produce more soap liquid, and when the soap liquid in the soap dispenser is less, the soap liquid will be less induced. At the same time, due to the viscosity of the soap, there is still a drop after the valve is closed. Moreover, for aesthetic reasons, the automatic induction soap dispenser generally does not have an external power source, but is driven by a battery. The battery brings environmental problems to life. The other is automatic induction to the soap faucet or automatic induction of soap, and the soap is placed under the liquid outlet. The job is to drive the gear pump through a motor to pump the soap from the low level to the high outlet. The drive energy has a battery and a power source. This also fails to solve the aforementioned problem of the soap dispenser. At the same time, due to the automatic induction to the soap faucet or automatic induction to the soap filling work, the motor drives the gear pump to pump the soap liquid to the high liquid outlet. When the gear pump stops working, the soap liquid returns from the liquid outlet, resulting in the first induction. Less fluid is not enough to wash your hands, and the second induction is more, resulting in waste. Furthermore, the gear pump works in a viscous soap (detergent), and any particulate impurities in the soap (dishwashing liquid) can cause fatal damage to the gear pump. Of course, the gear pump's soap inlet can be equipped with a filter to isolate the impurity particles, but the viscous soap (dishwashing liquid) has been running poorly on the gear pump, plus the filter screen of the inlet port to make the gear pump work. The environment is even worse.
