Liquid supply device

This creation relates to a liquid supply device, in particular to a liquid supply device that controls the timing of liquid discharge through the alignment and misalignment of the liquid discharge hole, and can replace the replenishment package, and further has a magnetic element to assist the return positioning.

The medical system in the world today is quite complete compared to the previous ones, ranging from global viral infections to small recurrent influenza, and they have developed corresponding special drugs or vaccines, but in addition to medical advances, It is also important to cultivate good hygiene habits yourself, and regular hand washing habits are the most basic way to maintain health. The hand is the organ that is closest to the food when eating. If it is not cleaned, it will eat the dirty stuff. Moreover, the air pollution is serious now. The dust and suspended particles in the air often cause the accumulation of dust in the living environment. It is often contaminated with dust, dust, and then touches the eyes, nose, and even the mouth, which can easily cause severe allergies. Therefore, the correct time to wash hands and the exact steps of hand washing are the only way to protect the health of yourself and others.

In public places or homes, soap or cleaning fluids are used to clean hands. The most common thing in public is soap or bottled hand wash. Due to the repeated use of soap, people have health concerns. Bottled hand wash is mostly made of disposable plastic bottles. Environmental concerns, in view of this, the use of soap dispensers filled with cleaning fluid has become a sanitary and environmentally friendly way.

Generally, soap dispensers are mostly installed in public toilets or restaurant bathrooms. The invention of soap dispensers has solved most of the above problems. It will not be used as a medium of communication due to repeated contact, and it also solves the problem of environmental protection for hand washing milk. However, while repeatedly filling the cleaning liquid into the soap tank accommodating tank, the cleaning of the accommodating tank has become another hygiene problem. We are only replenishing the used cleaning liquid repeatedly, but there will definitely be dirt in the interior over time. At the same time, the contaminated cleaning liquid will only get dirtier when it is washed, so this is another worry for soap dispensers.

In addition, in addition to the above problems, most of the pressing devices for soap dispensers are provided with springs to achieve repeated pressing actions, but it is often found that such devices are fatigued due to the elasticity of the springs, causing the buttons of the soap dispensers to fail to return to position. There is no way to repair it, which often causes trouble for users.

At present, although the soap dispensers on the market are more convenient than soaps and bottled clear liquids, many hygienic problems still arise due to the design, and the structural design has not allowed users to have more A good experience, therefore, needs better improved structure to solve the existing problems.

In view of this, this creation is to provide a liquid supply device, which includes a base, an outer casing, a displacement structure and a liquid supply structure.
