Description

technical field [0001] The present invention relates to a lotion pump device. Background technique [0002] Because of its exquisite design and convenient use, the lotion pump has been widely used in daily chemical and pharmaceutical industries. However, the existing lotion pump has a complex structure, is difficult to manufacture, and has high production costs. The existing lotion pump is connected with the bottle body and is inconvenient to assemble. [0003] In addition, due to the defects in the design of the existing lotion pump, there are disadvantages such as relatively slow starting of the pump during use, relatively unstable spraying volume, and the like. Can not meet the needs of users. [0004] Therefore, the existing lotion pump needs to be further improved. Contents of the invention [0005] The object of the present invention is to overcome the deficiencies in the prior art, and provide a lotion pump device with simple structure, convenient connection, qui...
