Spring external type perfume pump structure

Abstract

The invention discloses a spring external type perfume pump structure. The spring external type perfume pump structure comprises a pump body which extends into a bottle body, wherein a pump chamber isarranged on the pump body; a suction assembly is arranged in the pump chamber; a locking cover is connected to the pump body, and an aluminum oxide bayonet is connected to the locking cover; the lower end of the pump chamber is provided with a one-way valve; the upper end of the suction assembly is connected with a pressing part; the suction assembly comprises an upper pump rod, wherein a main spring is arranged between the upper pump rod and the locking cover; the upper pump rod is provided with a liquid inlet, and the upper pump rod is connected with a lower pump rod; the outer side of theupper pump rod is sleeved with a suction plug; an auxiliary spring is arranged between the upper pump rod and the suction plug; and a liquid inlet channel capable of communicating the pump chamber below the lower pump rod and the liquid inlet is formed between the lower pump rod and the suction plug. The spring external type perfume pump structure is simple in structure, adopts the spring externalstructure, avoids direct contact between the spring and the liquid in the pump chamber, and caused liquid pollution is prevented; and the main spring is arranged between the upper pump rod and the locking cover, the auxiliary spring is further arranged between the upper pump rod and the suction plug, and the double-spring structure is adopted, so that the pumping speed is high.

Description

【Technical field】 [0001] The invention relates to a miniature atomizer, in particular to a spring-mounted perfume pump structure. 【Background technique】 [0002] At present, there are many micro-sprayers on the market. These micro-sprayers can atomize and spray the liquid in the container by pressing the button or nozzle; their working principle is: using the principle of atmospheric pressure balance, the piston moves in the pump body to make the pump The gas in the body flows, the pressure becomes smaller, and the pressure outside the pump remains unchanged. A pressure difference is generated inside and outside the pump body, and the liquid is guided out of the pump body through the pressure difference. When the liquid meets the high-speed air flow, it is atomized instantly; Principle: In the same fluid, the larger the flow velocity, the smaller the pressure; the smaller the flow velocity, the stronger the pressure. These sprayer products are widely used in fields such as ...

Problems solved by technology

[0003] However, there are many existing structural parts, the installation process is complicated, and the production cost is high. The spring of the suction assembly of the traditional perfume pump will directly contact the liquid in the pump chamber. When the spring is rusted, the liquid will be polluted and unhygienic; and Because there is only one spring, the air pump speed is slow and the spray effect is poor
