Abstract
An improved structure of sprout assembly to allow it to be externally fixed to the faucet without welding and permit faucet and sprout to be plated first before connecting both to each other is characterized by that a connector in the faucet to engage a locking sleeve in the sprout, and a threaded tube being inserted through both of the connector and the locking sleeve.
Description
TITLE: SPROUT ASSEMBLY
BACKGROUND OF THE I~~VE~10N
(a) Field of the Invention The present invention is related to a sprout assembly, and more particularly, to one that can be externally locked to the faucet for fast assembly.
(b) Description of the Prior Art:
As people now demand more on the product quality, the rmanufactluers also demand more on the process quality since good process quality is the only way to effective upgrade the appearance of the product. ~~Tanufact~.u~ers of products such as the dial of a wrist'vatch, the appearance of an automobile and assembly of sanitary ware have been improving the assembly appearance to directly promote product image and indirectly stimulate the market demands and higher selling price. Fig. 1 of the accompanying drawing of the present invention shows a structure of the prior art of a sprout assemb:iy ?0 1 ~ adapted to a faucet 10. A'; illustrated in Figs. 2 and ? A for an assembly ~~f the sprout assembly ?0 and the faucet 10 in the prior art, the sprout assembly 20 is usually directly welded to a water outlet 13 on the faucet 10 to fix the sprout assembly ?0 to the outer circumference of the faucet 10. However, the prior art is found with the following defectives:
?0 1. The surface of the welded joint prevents easy access for finishing. As a protruded welded joint 22 is located at a comer where prevents easy access and the sprout assembiy 20 relates to a round tube malting the use of mechanical tools very di~cL~lt to access for surface finish: and even the finishing is provided, the surface remains comparatively rough.

SL1'v7MARY OF THE INVE~IfiION
The primary purpose o ~ the present invention is to provide an improved stn.icture of the sprout assembly ?0 that can be fixed to the faucet without welding, thus to improve the appearance of the finish product.
Another purpose of the present invention is to provide an improved structure of the sprout assembly ?0 that permits to have both of the sprout assembly 20 and the faucet 10 to be separately plated before iL~cing the sprout assembly 20 to the faucet 10 for rapid assembly of the faucet at a reduced production cost.
To achieve the proposes, a connector is provided in the faucet 10 to be inserted into a locking sleeve provided in the sprout assembly ?0.

DET~.ED DESCRIPTION OF THE PREFERRED EiVIBC)Df~IEi~ITS
Referring to Figs. ~, 4 and ~, the internal sa-ucture desists of a prefE;rred embodiment of the present invention is generally similar to that of a prior art.
Wherein, a temperature control valve 60 in shape compromising a bore 11 ~ inside a faucet 10 is fixed in approximately at the middle section of the bore 11.
A water outlet I2 connected through the interior of the temperature control valve 60 is provided at the outer circumference of the faucet in front of th.e temperature control valve 60. A cartridge stem 61 extends upward from the upper end of the temperature control valve 60 to control the mixing ratio of i 0 hot water and cold water inside the temperature control valve 60. Multiple water inlets 6~' are provided at the lower end of the temperature control valve 60 to introduce hot water and cold water into the temperature control valve 62 for mixing at a controlled temperature. On the outer circumference at the front of the temperature control valve 60 a water outlet 63 is provided to 1 ~ deliver the mixed hot and cold water through the water outlet l ~. An inwardly recessed cover 50 in the same outer diameter as that of the faucet is fixed to the upper part of the cartridge stem 61 so to cover up the top of the faucet 10. A chamber ~? is provided inside the cover ~0 so that a screw ~3 is used to externally secure the :over ~0 and the cautridge stem 61. A threaded ?0 handle ~ 1 is externally screwed into the front of thle cover 50. Those water inlets 62 are connected to multiple water pipes 70 to introduce both hot water and cold water. A cartridge 80 is screwed to the lower part of the faucet 10.
A packing 81 is provided at where below the cartridge 80 to support the faucet on a sink.
The improved structure of the sprout assembly is essentially made by having fixed a hollow, cylindrical connector 30 into the water outlet 1?.
Female threads are provided on the inner circumference of the connector 30 to engage a threaded tube 40 and protruding forward with its outer circumference rued at its rear to the water outlet 12 and a groove being provided on its front 10 circumference to receiver insertion of an O-ring 32. The tube 40 related to a threaded tube provided with male threads on its outer circumference to be inserted through the connector 30. The rear end of the threaded tube 40 is formed with a nut in diameter slightly larger than that of the threaded tube and the center of the threaded tube is made in hexagonal to permit use of a 1 ~ hexagonal wrench to ii~~ the tube. The threaded tube 40 after penetrating through the bore of the connector 30 is screwed to a locking sleeve 21 fixed at the rear in a sprout assembly ''0 by holding against the outer circumference of the sprout assembly 20 in relation to the faucet 10. The sleeve 21 related to a recessed hollow cylinder has its outer circumference fixed to the bore of the ?0 sprout assembly ~0. and female threads are provided in the bore of a hole provided on the outer circurr~erence of the sleeve 21 in the direction toward the sprout assembly 20 to be locked into the outer diameter of the threaded tube 40. The lamer bore in the rear of the hole provides a mobile travel for the insertion of the outer circumference of the connector 30.
When assembled, continuous spot welding of mechanical process a used to respectively fi~~ the connector 30 and the locking sleeve 21 to the faucet 10 and the sprout assembly 20 before forthwith entering into the next plating process. Then the threaded tube 40 is used as a packing to secure either manually or mechanically both of the connector 30 and the locking sleeve 21 for the faucet 10 to enter into next assembly process.
The present invention is characterized by that:
1. Whereas the connector and the locking sleeve can be processed and produced by automation machine, and both are respectively fixed to the faucet and tl'~e sprout by spot welding before entering the plating process.
i ~ Furthermore, as both of the connector and the locking sleeve are welded at where not visible from the appearance, the plating process can be done faster and the plating quality will not be affected by the welded joint.
2. Since no soldering job is required beriveen the sprout and the faucet, the finishing process is skipped to prevent any defects to the plated finish., meaning a si~ificant sav~.ng for purchasing expensive finishing tools otherwise required in the conventional process.
through the conventional welding process before entering into the next process of plating for finishing. However, during the plating process, the rough surface of the welded joint 2? will fail a consistent surface attachment of the plated surface. Conseduently the plated surface on the welded joint 22 will start to strip ol~to increase the percentage of defectives of a production lot.
