A double spring lotion pump

Abstract

The invention discloses a double-spring lotion pump, which includes a combination cover, a pump body assembly is arranged inside the combination cover, and a nozzle button capable of driving the pump body assembly is arranged on the upper part of the pump body assembly, and the pump body assembly includes a pump chamber , there is a locking cover on the upper inner wall of the pump chamber, an upper pump rod is arranged inside the locking cover, and a limit step is arranged on the upper pump rod. The upper pump rod is set in the combination cover, the nozzle button is connected to the upper pump rod, a piston is sleeved on the outer wall of the upper pump rod under the limit step, and an auxiliary spring is arranged between the piston and the limit step. Set on the upper pump rod, the lower pump rod is set in the pump chamber below the upper pump rod, the positioning step is arranged at the lower part of the pump chamber, the main spring is arranged between the lower pump rod and the positioning step, and the lower pump chamber is provided with pump beads. Objective To provide a double-spring lotion pump with simple structure, low production cost, convenient use, fast start-up and relatively stable discharge volume.

Description

technical field [0001] The invention relates to a double spring lotion pump. 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 many parts, complex structure, difficult manufacture, and high production cost. In addition, due to the defects in the design of the existing lotion pump, the pump is relatively slow during use, and the ejection volume is relatively unstable. shortcoming. Can not meet the needs of users. [0003] Therefore, the existing lotion pump needs to be further improved. Contents of the invention [0004] The purpose of the present invention is to overcome the deficiencies in the prior art, and provide a double-spring lotion pump with simple structure, low production cost, convenient use, fast start-up and relatively stable discharge volume. [0005] In order to achieve the above object, the present i...
