Perfume pump with external spring

Abstract

The invention relates to a perfume pump with an external spring. The perfume pump with the external spring is designed to solve the technical problem that existing like products are not good enough in structural design. A valve needle, a piston, the special-shaped spring and a valve rod of the perfume pump form a valve needle assembly. The valve needle assembly, a pump body, a glass ball and an inner plug form a pump body assembly. An aluminum oxide press cap, a spraying piece and a head cap form a pump head assembly. The perfume pump with the external spring is characterized in that the special-shaped spring is arranged on the external diameter of the valve rod between the piston in the pump body and the inner plug, and the two ends of the special-shaped spring are fixedly connected with a ring groove of the piston and a pump opening of the pump body respectively. The special-shaped spring is in a Y shape. The piston is limited on a needle head at one end of the valve needle, and a needle rod at the other end of the valve needle is sleeved with a center hole of the valve rod. A ring groove at the needle rod end of the valve needle is buckled with a ring buckle on the internal diameter of the valve rod, and a water outlet groove is formed in the external diameter of the valve needle and is from the ring groove of the valve needle to the needle head. An inner ring of the piston is in sliding fit sealing with the external diameter of the valve rod, and a channel between the water outlet groove of the valve needle and the piston is opened when the valve rod, the piston and the valve needle move to the side of the glass ball.

Description

technical field [0001] The invention relates to a miniature atomizer, which is an external spring perfume pump. 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 strong. These sprayer products are widely used in fields such as gardening, hairdressing, beauty, etc., some of which press the micro-sprayer of the cap, mainly used in perfume spraying in the beauty field, or perfume pump. In order to prevent the chemical reaction between the metal spring in the pump body and the liquid perfume, thereby affecting ...
