Self-suction liquid soap feeding device

Abstract

The invention relates to a liquid soap feeding device, in particular to a self-suction liquid soap feeding device which utilizes the water pressure to suck liquid soap. The device is provided with a liquid suctionor and a liquid suction controller thereof which use the water pressure as power to change the volume of the liquid suction cavity and achieve the aim of sucking or squeezing out the liquid soap. Therefore, the parts such as the motor and the gear pump are not needed; and the squeezing amount of the liquid soap is only related to the variation quantity of the volume of the liquid suction cavity, thus the squeezing amount of the liquid soap is stable and the squeezing amount can be conveniently changed by adjusting the volume of the liquid suction cavity.

Description

technical field [0001] The invention relates to a faucet of a soap liquid supply device, in particular to a self-suction soap liquid supply device capable of self-absorbing soap liquid by water pressure. Background technique [0002] Present soap dispenser, the modal one is a mechanical type one press soap dispenser. 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 demanding quality of life, people are more and more inclined to automation, especially in public places. Automatic induction soap dispenser / automatic induction soap dispenser also came into being. The automatic induction soap dispenser sets the soap liquid at a high level, and controls the opening and closing of the bottom valve through the motor to release the soap liquid through the free drop. But this automatic induction soap dispenser just goes out soap liquid when soap liquid just fills up, and in...

Problems solved by technology

This can not solve the problem of aforementioned soap dispenser equally

At the same time, because the automatic induction soap feeding faucet or the automatic induction soap filling work is that the motor drives the gear pump to pump the soap liquid to the high-level liquid outlet. When the gear pump stops working, the soap liquid flows back from the liquid outlet, resulting in the first induction. If there is less fluid out and not enough to wash hands, the second induction will be too much, resulting in waste

Furthermore, the gear pump works in viscous soap (detergent), and any particle impurities in the soap (detergent) will cause fatal damage to the gear pump

Of course, a filter screen can be installed at the soap liquid inlet of the gear pump to isolate impurity particles, but the viscous soap liquid (detergent) has already hindered the operation of the gear pump, and the filter screen at the liquid inlet makes the gear pump work The environment is even worse
