Problems solved by technology

[0002] Spray is used in cosmetics and other fields. The spray pump is one of the key components. After the traditional spray pump is pressed, the liquid in the pump body is sprayed out. During the spraying process, the pressure in the pump body gradually decreases. Insufficient pressure causes the liquid to not be atomized, resulting in dripping. In addition, the traditional spray pump uses a spring as a booster, and the spray force is too strong.

Abstract

The invention discloses a hand pressing type atomizing pump, and relates to the technical field of atomizing parts. The hand pressing type atomizing pump comprises a pump body, a sealing ring located at the bottom end of the pump body and a sealing ball located at the bottom end of the pump body. The sealing ball is located on the upper side of the sealing ring. The hand pressing type atomizing pump further comprises a lower piston inserted to the upper end of the pump body, an upper piston sleeving the upper end of the lower piston and a spring located in the pump and used for driving the lower piston to move to the direction away from the pump body. A via hole is formed in the upper end of the upper piston, the lower end of the lower piston is a lower sealing part attached to the inner wall of the pump body, the lower end of the upper piston is an upper sealing part attached to the inner wall of the pump body, an annular ventilation groove is formed in the position, between the upper sealing part and the lower sealing part, of the inner wall of the pump body, a hole is formed in the position, between the ventilation groove and the lower sealing part, of the pump body, and an annular liquid-permeable groove is formed in the position, between the lower sealing part and the sealing ball, of the pump body. The hand pressing type atomizing pump is free of water dripping and moderate in spraying force.

Description

technical field [0001] The invention belongs to the technical field of spray parts, in particular to a hand-pressed spray pump. Background technique [0002] Spray is used in cosmetics and other fields. The spray pump is one of the key components. After the traditional spray pump is pressed, the liquid in the pump body is sprayed out. During the spraying process, the pressure in the pump body gradually decreases. Insufficient pressure causes the liquid to not be atomized, resulting in dripping. In addition, the traditional spray pump uses a spring as a booster, and the spray force is too strong. Contents of the invention [0003] The purpose of the present invention is to overcome the shortcomings of dripping phenomenon and too strong spraying force in the prior art, and propose a hand-pressed spray pump with no dripping phenomenon and moderate spraying force. [0004] In order to achieve the above object, the present invention adopts the following technical solutions: ...
