Description

A kind of plastic faucet

Technical field

The present invention relates to a kind of plastic faucet.

Background technique

The valve seat of the plastic faucet of Xiao Shouing bottom is generally uneven in the market, its main cause need below the valve seat bottom to be the position of injection moulding to have big thickness, it is one-body molded that valve seat bottom is provided with the position of intake tunnel and exhalant canal once on the water tap, and should locate complex structure, passage is more, cause the valve seat bottom when injection moulding, to shrink inhomogeneous easily, cause the valve seat deformation of bottom bigger, concave and convex plane, and this state of valve seat bottom makes mangetic core assembly be difficult to configuration, the sealing effect that mainly is spool and valve seat bottom is relatively poor, leak easily, generally need through turning this valve seat bottom of polishing just applicablely, therefore increased manufacturing process, also increased manufacture cost.

Summary of the invention

Technical problem to be solved by this invention provide a kind of valve seat bottom can be when leading main casing molding and forming very level and smooth plastic faucet just.

For this reason, plastic faucet provided by the invention comprises leading main casing, the tap main casing comprises valve seat, intake tunnel and exhalant canal, the tap main casing comprises upper shell and lower shell body, upper shell comprises the valve seat bottom at least, the below of valve seat bottom, upper shell bottom forms smooth flat, the water inlet of valve seat only is set on this smooth flat or water inlet and osculum only are set, the thin layer of only being separated by between the bottom of valve seat and the smooth flat, upper shell and lower shell body are adjacent to mutually in the smooth flat place and sealing engagement mutually.

Because plastic faucet provided by the invention is divided into upper shell and two parts of lower shell body, wherein the below of upper shell bottom valve seat bottom forms smooth flat, and less water inlet of bore and osculum only are set on this smooth flat, compare the structure that traditional water tap valve seat place large size is provided with intake tunnel and exhalant canal, the structure that the present invention adopts is shunk evenly the valve seat bottom when injection moulding, and then distortion is also less relatively, the thin layer of only being separated by between the bottom of valve seat and the smooth flat in addition, mould can be at valve seat bottom and smooth flat upper support when injection moulding, add thickness attenuation between the bottom of valve seat and the smooth flat, make the water tap valve seat bottom shrink more even more, the distortion that takes place is also minimum, finally can obtain smooth smooth valve seat bottom, make spool being provided with on valve seat convenient, the sealing effect of spool and valve seat is better.
