Buckle type protective structure and emulsion pump device

Abstract

The invention discloses a buckle type protective structure and an emulsion pump device. The buckle type protective structure comprises a bent nozzle and a locking cover, wherein the outer wall of the locking cover extends downwards to form a limiting snap ring, a protective cover is clamped to the locking cover, and a buckle is arranged at the lower end of the protective cover and clamped at the end of the limiting snap ring. The emulsion pump device comprises a pump chamber, the bent nozzle is arranged at the upper end of the pump chamber, the upper portion of the pump chamber is sleeved with a bottle cover, the portion, above the bottle cover, of the pump chamber is sleeved with the locking cover, the buckle type protective structure is arranged between the bent nozzle and the locking cover, a pump rod is arranged in the pump chamber, the upper end of the pump rod is connected with the bent nozzle, a piston is integrally formed at the lower end of the pump rod, a limiting step is arranged on the lower portion of the pump chamber, a reset spring is arranged between the pump rod and the limiting step, a liquid inlet is formed in the portion, below the limiting step, of the pump chamber, and a pump bead is arranged in the liquid inlet. The buckle type protective structure and the emulsion pump device are simple in structure, the bent nozzle can be firmly locked in the protective cover, error press is effectively prevented and use is convenient.

Description

technical field [0001] The present invention relates to a buckle-type protection structure, and the invention also relates to a lotion pump device comprising the above-mentioned buckle-type protection structure. Background technique [0002] Because of its exquisite design and convenient use, the lotion pump has been widely used in daily chemical and pharmaceutical industries. Existing spray caps for lotion pumps have a relatively complicated structure. The curved nozzle and the locking cap are generally connected by threads. When using it, the curved nozzle needs to be unscrewed. It is relatively troublesome to screw on the locking cap. In order to solve this problem, the existing method is to set an additional outer cover on the spray cover, but the existing outer cover is easy to fall off during use, the connection is not firm, it cannot play a protective role, and it is inconvenient to use. [0003] Therefore, the existing lotion pump device needs to be further improve...
