A spray pump device with fast pumping

Abstract

The invention discloses an atomizing pump device capable of quickly starting to pump. The atomizing pump device comprises a connecting cap. A pump unit is disposed inside the connecting cap. The upper portion of the connecting cap is provided with a button which can be used to drive the pump unit to operate. The connecting cap is provided with a connecting convex ring sleeved with a dust cap. The button is disposed inside the dust cap. The pump unit comprises a pump chamber. The inner wall of the upper portion of the pump chamber is provided with a locking cap. An upper pump rod is disposed inside the locking cap and provided with a limit step. The button is connected to the upper pump rod. A piston sleeves the outer wall of the upper pump rod below the limit step. An auxiliary spring is arranged between the piston and the limit step and sleeves the upper pump rod. A lower pump rod is arranged inside the pump chamber below the upper pump rod. The lower portion of the pump chamber is provided with a positioning step. A main spring is arranged between the lower pump rod and the positioning step. The lower portion of the pump chamber is provided with a pump ball. The atomizing pump device provided according to the aim is simple in structure, dust proof, sanitary, capable of quickly starting to pump and relatively stable in ejection volume.

Description

technical field [0001] The invention relates to a spray pump device with fast start-up. Background technique [0002] Due to its exquisite design and convenient use, the spray pump has been widely used in daily chemical and pharmaceutical industries. However, after the existing spray pump is unpacked, the nozzle of the spray pump will be exposed outside for a long time, and pollutants such as dust are easy to enter the nozzle during use, causing pollution. In addition, due to design defects, existing spray pumps have disadvantages such as relatively slow starting of the pump during use, relatively unstable discharge volume, and the like. Can not meet the needs of users. [0003] Therefore, the existing spray 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 spray pump device with simple structure, dustproof and hygienic, fast pumping, relatively stable...
