Water nozzle capable of preventing valve cover from being separated out

Abstract

The invention discloses a water nozzle capable of preventing a valve cover from being separated out. The water nozzle comprises a valve body, the valve cover, a fixed ceramic chip, a movable ceramic chip and a valve rod, wherein the valve cover is arranged at the upper end of the valve body; the fixed ceramic chip, the movable ceramic chip and the valve rod are arranged in the valve body from bottom to top. The water nozzle is characterized in that the valve rod is of a hollow cylindrical structure of which both ends are open; the top of the valve rod extends outwards to form an inverted hook; the valve cover comprises a lower cover sleeving the upper end of the valve body in a screw thread manner and a top cover arranged on the lower cover; the lower cover is of a hollow cavity structure of which the upper end is closed and the lower end is open; the sealed port of the lower cover is provided with a through hole positioned on the same straight line as the axis of the valve rod; the top cover covers the sealed port of the lower cover in a sphere shape; a connecting rod positioned on the same straight line as the axis of the valve rod is arranged at the bottom of the top cover. After assembling is completed, the upper end of the valve rod passes through the through hole and the inverted hook is buckled on the sealed port of the lower cover, so that the lower cover cannot fall out of the valve rod and the water nozzle is more convenient and durable to use; the connecting rod on the top cover is inserted into the valve rod to be covered on the sealed port of the lower cover, so that dust and the like are prevented from falling into the water nozzle.

Description

technical field [0001] The invention relates to a faucet with a ceramic valve core, in particular to a faucet which prevents a valve cover from falling out. Background technique [0002] The existing ceramic spool faucet includes a valve body, a valve cover arranged on the upper end of the valve body, a fixed ceramic piece, a moving ceramic piece and a valve stem arranged in the valve body from bottom to top, and the valve stem is sleeved on the outside of the valve stem. The rod is fixed to the fixed three claws in the valve body. The bonnet is a hollow cavity structure with the upper end closed and buckled upside down on the valve body. A valve stem slot extending to the lower end of the bonnet is opened in the center of the bonnet. The upper end of the valve stem is inserted into the valve stem socket from bottom to top. In the groove, the valve stem and the valve cover form a fixed connection. When the bonnet is rotated, the valve stem rotates together with the bonnet,...

AI Technical Summary

Problems solved by technology

With such a structure, since the valve stem is pressed into the valve stem slot on the bonnet, when the bonnet is rotated, the valve stem relies on the friction between it and the inner wall of the valve stem slot. After a period of time, the friction between the two will decrease, the gap between the two will increase, and there will be no other points of action on the inner wall of the valve stem and the valve stem slot, making the valve cover easy to come out, or easy to be pulled out during use, not only Affect the use, and dust, water, etc. will enter the valve core to damage the valve core, affecting the service life of the faucet
