Description

Pump core
Technical field
The utility model relates to the pump core of emulsion pumps and vacuum pump, is a kind of pump core.
Background technology
Lotion pump and vacuum pump are a kind of containers for emulsion access, it mainly utilizes the principle of push type micro-sprayer, and in head cap, omit the setting of catch, thus makes emulsion after suction pipe, the pump housing, flow out from the head cap of shower nozzle, and ejection can not be atomized due to the stop of catch.The difference of two is mainly whether the side of the pump housing is provided with through hole, and whether is provided with suction pipe; The agent structure of this type of lotion pump and vacuum pump is emulsion bottle cap, and pump core, and some of them pump core adopts the structure of external spring.As the application number 201410567188.8 disclosed in Chinese patent literature, Shen Qing Publication day 2015.03.04, denomination of invention " rotary and telescopic vacuum shower nozzle and using method thereof "; The head cap of this vacuum shower nozzle is arranged in outer cover, the top circle mouth external diameter side of head cap is provided with spray orifice, the bottom turns mouth external diameter of head cap is arranged with column spinner, column spinner buckles into the rotation inclined hole that outer cover inward turning is turn-taked, the two ends rotating inclined hole are respectively equipped with horizontal end slot, great circle is connected with bottle, and the suction pipe of great circle stretches in bottle; Its main points are that described outer cover and great circle are fastened and connected formation housing, the stair ring mouth of the circle barb and great circle internal diameter that rotate circle bottom turns mouth external diameter fastens, pump core assembly is arranged in the cavity that above-mentioned rotation circle and great circle form, spring in this cavity encloses with rotation respectively, great circle offsets, and the fluid hole of pump core assembly is communicated with the spray orifice of head cap by pipe link, Connection Block successively.Pump core in above-mentioned vacuum shower nozzle adopts external spring, but the fluid mode of its pump core is identical with existing like product, or realizes fluid by the through hole of needle centre hole side, and which liquid outlet quantity is limited, once through hole blocking directly can affect the effect of fluid.
Summary of the invention
For overcoming above-mentioned deficiency, the purpose of this utility model provides a kind of pump core, makes it solve existing like product fluid effect stability when applying poor, the technical matters that liquid outlet quantity is less.Its objective is and to be achieved through the following technical solutions.
A kind of pump core, pump housing Single port and the bayonet mount interference seal of this pump core fasten, one end of valve rod is stretched in the pump housing by bayonet mount, needle one end fit in the centre hole of valve rod and the pump housing is connected as a single entity, the external diameter of valve rod is provided with spring, the two ends of spring respectively with the port outside diameter of the valve rod other end, and bayonet mount offsets, needle external diameter in the pump housing is provided with piston, and the other end inlet opening in the pump housing is provided with bullet cover; Moved up and down by pressing belt ovable valve stem, the one-way membrane feed liquor of bullet cover is opened simultaneously, and fluid is closed, and produces pressure difference, enter the liquid in the pump housing and flowed out by the centre hole of valve rod in the pump housing.Its main points are the T-shaped screw of described needle, and needle is fastened by the button bit in collar footpath in the nail catching groove of tip outer diameter and valve rod centre hole and is connected as a single entity; The centre hole inner diameter wall of valve rod is provided with valve rod rib, and the inner diameter wall of piston is provided with piston rib.Thus it is different from the centre hole that liquid in existing similar pump core flows into valve rod by the through hole of needle, in this pump core, liquid covers in the pump housing by bullet, flowed into the centre hole of valve rod again by the piston rib of piston and the valve rod rib of valve rod, and flow out from the centre hole of valve rod.
