Press, the sink on the market surface of the table, for durability, aesthetics or easy to clean and maintain, most of them will use stainless steel metal sink. The metal sink is used for washing kitchen utensils, dishes or fruits and vegetables. In order to avoid the blockage of the drain pipe, the water drop head is usually locked on the water outlet of the metal water tank, and the drain hole is filtered by the filter hole or mesh of the filter element in the water drop head. Miscellaneous. The production of metal sinks, based on cost considerations, is generally a thin-shell (thin-wall) tank formed by sheet metal processing technology. Because the wall thickness of the bottom of the tank is thin, it is difficult to connect the fixed water head at the outlet end; for example, the water-falling head is used. Structure, such as No. M383593, "Structural improvement of the falling head of the sink of the flow table" Taiwan's new patent case is that the falling head is in the trough of the trough, and is pierced from the water outlet at the bottom of the trough, although the retaining edge of the falling head On the bottom surface of the tank, with the water stop washer, the bottom end of the water tank can be screwed and locked on the external thread section of the water drop head by a lock ring, and the water head is fixed on the water outlet, however, If the water washer is thin or does not match the water stop gasket, a gap will be formed between the bearing edge and the bottom surface of the groove. This gap not only hides dirt (mold mold, produces odor), is difficult to clean, maintain or maintain, and also Affect the beauty and hygiene of the sink.

The main purpose of the present invention is to provide a metal water tank assembly drop head structure, which is provided with a water outlet at the bottom of a metal sink; the water outlet is connected with a water drop head, and the water head has a class slot inside, the class The bottom end of the trough is provided with a connecting portion for connecting the drain pipe; the improvement is that the bottom of the trough of the metal trough is inclined and concave, and a water guiding hole portion is formed, and the water outlet is formed in the hole of the guiding trough The bottom end of the aperture is connected with a metal material assembly connecting ring, the outer edge of the body of the assembly connecting ring is formed with an external thread, and the top end is opposite to the water outlet, forming a neck portion combined in the water outlet. Between the neck and the periphery of the orifice of the water outlet, there is a feeding gap, the feeding gap is filled with a welding material, and the assembly connecting ring is welded and fixed to the guiding hole portion, and the welding material and the welding material Grinding the surface of the neck such that the inside of the assembly connecting ring communicates with the hole of the guiding trough; the open end of the trough of the falling head is formed with a bearing ring frame opposite to the bottom end of the assembled connecting ring The outer edge of the receiving ring frame portion is provided with a locking sleeve. The inside of the locking sleeve is formed with an internal thread relative to the external thread of the assembly connecting ring, and is externally connected by the internal thread and the assembled connecting ring. The screw is screwed, and the bearing ring frame portion of the water drop head is locked on the bottom end of the assembly connecting ring to engage the water outlet on the hole of the water guiding trough; The nozzle is completely integrated by the surface of the open end of the class slot extending to the falling head of the assembly connecting ring, so that the surface of the water outlet of the metal sink can be achieved by a seamless effect, and the metal sink is improved in appearance and easy to clean and maintain. Health benefits.

The second objective of the present invention is to provide a metal sink assembly drop head structure, wherein the open end of the class slot of the drop head is placed on the ring frame portion, and a filter basket is mounted, and the inlet end of the filter basket is provided. An upper filter member is inserted in the interior of the assembly connecting ring, the upper filter member is provided with a filter hole portion and a cover groove is formed, and the cover groove is provided with a sealing portion for closing the filter hole The water tank cover; when the water is filled in the metal water tank, the water tank in the metal water tank can be prevented from falling into the water head by the water tank cover. Otherwise, when the water tank cover is opened, the dirty sewage liquid in the metal water tank can be drained through the falling head, and the water can be utilized. The filter hole portion of the upper filter member and the mesh of the filter basket filter the impurities to achieve the double filtration effect of the drainage.

A further object of the present invention is to provide a metal water tank assembly drop head structure, wherein a bottom sealing end of the assembly connecting ring and the bearing ring frame portion of the water drop head are lined with a sealing washer, when locked When the internal thread of the sleeve is screwed into the external thread of the assembly connecting ring, the screw-tight locking force of the locking sleeve is used to interlock the pressing ring frame to pressurize the sealing washer, thereby causing the water to be squeezed. The falling head is locked on the assembly connecting ring to achieve the effect of preventing leakage of water and liquid.
