Press type external spring perfume sprayer and round trip press method thereof

Abstract

The invention relates to a press type external spring perfume sprayer and a round trip press method thereof. The perfume sprayer and the round trip press method are designed to solve the technical problem of poor structural designs of like products. A valve needle component comprises a piston, a valve needle, an inner piston, long springs, short springs and a valve rod; a pump body component is composed of the valve needle component, a pump body and a glass bead; a pump head component is composed of an aluminum oxide press cap, a spray slice and a head cap, wherein key points are that the piston sleeves the valve needle of the valve needle component in an interference manner, the inner piston sleeves the piston in an interference manner, the pump body is buckled with the inner piston, and the valve needle is buckled with the valve rod; the long springs are arranged between the inner piston and the valve rod, the short springs are arranged between the valve rod and the valve needle, and the long springs are arranged on the outer diameters of the short springs; the valve needle component enables that round trip press is realized through the long springs and the short springs, and the piston is limited through terrace terminal angles on the inner diameter of the pump body. The press type external spring perfume sprayer and the round trip press method thereof have reasonable structural designs, high leak tightness, good convenience in assembly and use, and sound effect of round trip press spray, and are suitable for perfume and the like products, as well as structural improvement of the like products.

Description

technical field [0001] The invention relates to a miniature sprayer, which is a pressing type perfume sprayer with an external spring and a double-way pressing method thereof. Background technique [0002] At present, there are many micro-sprayers on the market. These micro-sprayers atomize and spray the liquid in the container by pressing the wrench or the head cap; When the pressure becomes smaller, the pressure outside the pump body remains unchanged, and a pressure difference is generated inside and outside the pump body. The liquid will flow out of the pump body through the pressure difference. , the flow velocity is high, the pressure is low; the flow velocity is small, the pressure is high. These sprayer products are widely used in fields such as gardening, hair salons, and beauty treatment. Some of the micro sprayers that press the cap are mainly used in perfume spraying in the beauty field. Such as the application number 200510061898.4 disclosed in the Chinese pat...
