Description

Technical Field

[0001] The utility model relates to the technical field of chemical production, in particular to a liquid feeding device. Background Art

[0002] Toilet cleaning liquid is primarily made from hydrochloric acid, utilizing its strong acidity to react with carbonates to produce carbon dioxide and water, effectively removing dirt from urinals and toilet bowls. To prevent the pungent odor of hydrochloric acid and the stratification and precipitation caused by various compounds, external additives are added during the production process.

[0003] The original design of the toilet cleaning liquid device had the additive feeding port at the top of the preparation tank. Every time the toilet cleaning liquid was prepared, employees had to carry the additive bucket up and down the stairs several times and pour a certain amount of additive into the feeding port at the top of the preparation tank. This was not only time-consuming and labor-intensive, but going up and down the stairs also increased safety risks.

[0004] Therefore, there is an urgent need for a liquid feeding device that can solve the above problems. Utility Model Content
