Mini perfume pump structure with external spring

Abstract

The invention discloses a mini perfume pump structure with an external spring. The mini perfume pump structure comprises a pump body extending into a bottle body, wherein a pump chamber is arranged onthe pump body; a suction component is arranged in the pump chamber; the upper end of the pump body is connected to a locking cover on the pump body; a one-way valve is arranged at the lower end of the pump chamber; a button is connected to the upper end of the suction component; a bayonet cover is arranged between the pump body and the bottle body; the suction component comprises an upper pump rod; a spring is arranged between the button and the locking cover; the lower end of the upper pump rod is connected to a lower pump rod; the upper end of the lower pump rod extends into a suction channel and is fixedly connected to the upper pump rod; a liquid flow channel is formed between the outer side of the lower pump rod and the inner wall of the upper pump rod; and a suction plug sleeves theouter side of the upper pump rod. The mini perfume pump structure is simple in structure; through the adoption of the external spring structure, the liquid pollution caused by the direct contact between the spring and the liquid in the pump chamber is avoided, and the mini perfume pump structure is clean and sanitary, fast in air pump speed, stable in ejection amount and good in spraying effect.

Description

【Technical field】 [0001] The invention relates to a miniature sprayer, in particular to a miniature 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...

Problems solved by technology

[0003] However, there are many existing structural parts, and the processing and manufacturing are complicated, which makes the assembly extremely inconvenient and the production cost is high; and the spring of the suction component of the traditional perfume pump will directly contact with the liquid in the pump chamber, and when the spring gets rusty, it will cause damage to the liquid. pollution, unsanitary
