Technical Field

The invention relates to the field of sanitary ware, in particular to a faucet with a valve core convenient to disassemble and replace.

Background

Most of the existing taps used in families and hotels have the functions of cold water and hot water, and the cold water and hot water taps have a fatal weak point, namely a plastic valve core. All things being kitchen taps, washbowl taps, shower taps, etc. The plastic valve core is aged and cracked after being used for a long time, and the matched shell is mostly metal, and most of the plastic valve core is brass or 304 stainless steel. Because brass or 304 stainless steel material all need the hardness more durable than the plastics material, often the case goes out the problem, and the casing is still good, repaiies not too much understanding, also does not have the instrument, causes the waste. If the valve core can be conveniently replaced, the faucet is designed as such, and the valve core can be conveniently detached and replaced. The operation is simple, and the service life of the faucet can be greatly prolonged once the operation is understood.

Disclosure of Invention

The invention is realized in this way, and consists of a handle, a decorative cup, a gland, a valve core and a shell. Wherein the shell is an existing universal shell; a control rod is arranged on the valve core, the upper part of the control rod is a cylinder, and a clamping groove is formed in the surface of the cylinder; the gland is of a hollow structure, the lower part of the outer side of the gland is provided with threads, and the upper part of the gland is provided with a wrench position; the decorative cup is also of a hollow structure, the outer side of the decorative cup is contracted into an upper opening from bottom to top in an inward arc way, the bottom of the decorative cup is contracted into a lower opening inwards, and the lower opening is tightly matched with a wrench at the upper part of the gland; a wrench hole is arranged on the handle and is just matched with a wrench at the upper part of the gland; the inside of the handle is provided with a central tube, a circular hole cavity is arranged in the central tube, a clamping point is arranged at the inlet of the circular hole cavity, the central tube in the handle corresponds to the control rod on the valve core, the circular hole cavity is aligned to the cylinder, and the clamping point is aligned to the clamping groove, so that the central tube can be sleeved and locked in a tight fit manner. Assembling: firstly, a valve core is arranged in a shell; secondly, the gland is sleeved and pressed on the valve core, and a wrench hole on the handle is sleeved on a wrench position on the gland to be screwed rightwards; thirdly, the decorative cup is sleeved and buckled on the convex spanner position in a tight fit manner; and fourthly, aligning the central pipe inside the handle to the top end of the valve core control rod, aligning the circular hole cavity to the cylinder and aligning the clamping point to the clamping groove, downwards applying force to the sleeve, idling to the right until stopping after feeling to the end, and then rightwards rotating by 90 degrees by applying force for locking. The disassembly steps are carried out in reverse order, and the valve core with the same specification can be purchased in the previous store.
