In the process that the liquid sealing part returns to the initial position, the sealing connecting rod seals the liquid rising channel, the pressure of the liquid channel is reduced, the ball is raised, the liquid channel at the lower end is opened, the liquid rises to the liquid channel through the suction pipe, meanwhile, the air inlet channel of the gas seal is opened, the air enters the air cavity, when the button returns to the initial position, the ball sags under the action of gravity, and the sealing liquid backflow channel and the air leakage channel are closed. In the prior art, metal springs have the following problems in the specific environment for packaging household chemicals:

1. the metal spring is of a multi-layer ring-shaped structure, the diameter of the metal spring wire is small, when the liquid distribution device is automatically assembled, the springs of the multi-layer ring-shaped structure are very easy to wind together in the material container and are not easy to separate, and therefore the assembly efficiency of products is low.

2. With the long-term use of the liquid dispensing device, the elastic force of the metal spring is easy to attenuate, and the elastic force is not stable enough.

3. The metal spring is easy to rust and pollute the contact under normal environment, and is easy to corrode and break under acidic environment, so that the service life of the product is shortened.

4. Except that the spring is the metal material in the liquid distribution device, all the other parts are the plastic material, and when the product was retrieved, need to dismantle metal spring, lead to recovery efficiency lower.

5. The metal spring processing production efficiency is low, and the cost is high.
