Description

Technical Field

[0001] The utility model relates to the field of sanitary products, and particularly relates to a faucet. Background Art

[0002] When producing a washbasin faucet (countertop faucet), generally, the sand casting process is adopted to form structures such as the main body and the water outlet arm. At the same time, in the later stage, the valve core installation position needs to be machined by boring the inner end face, and each water channel needs to be machined by drilling holes in the main body, and butt threads are machined at the water channel openings; a threaded cavity is reserved at the bottom of the main body for installing a threaded installation cylinder. Since the water inlet holes and the water outlet holes of the cold and hot water valve cores are offset from the central axis of the valve core, the water inlet holes at the bottom of the main body also follow the offset when drilling holes, which causes the water inlet pipeline to also be offset when connected, and it is easy to interfere with the inner wall of the threaded installation cylinder at the bottom of the main body. Therefore, some manufacturers will directly lead the butt thread to the bottom end face of the main body by welding a copper pipe during production, so as to ensure normal water connection; as a result, the overall process is complex, the material loss is large, the production cost is relatively high, and it is overly dependent on external processing by other industries.

[0003] In response to the above problems, the applicant applied on May 18, 2023, and obtained authorization on October 20, 2023. A washbasin faucet with the patent number CN202321239338.3 includes a through cylinder, and water outlet holes are provided on the outer wall of the cylinder; it also includes a water distribution plate, and the water distribution plate is provided with a first water inlet channel, a second water inlet channel, and a water outlet channel. One end of the water outlet channel on the side of the water distribution plate corresponds to the water outlet hole and is welded and butted with the water outlet hole. The lower surface of the water distribution plate is provided with a first water inlet pipe and a second water inlet pipe, one end of which is welded to the first water inlet channel and the second water inlet channel, and the other end extends downward to the lower end of the cylinder. Docking heads are provided at the lower ends of the first water inlet pipe and the second water inlet pipe; a gland for fixing the cold and hot water valve core on the water distribution plate is provided at the upper end of the cylinder; a water outlet arm corresponding to and communicating with the water outlet hole is provided on the side of the cylinder, and a water outlet nozzle is provided on the water outlet arm.

[0004] Although this utility model adopts a water distribution plate structure, there is still a problem of excessive thickness. The inner diameter of the conventional water outlet channel is 6 mm, and adding at least 1 mm of designed wall thickness will result in the thickness of the water distribution plate reaching 8 mm, thereby increasing the overall weight and also having a relatively high requirement for the drilling accuracy. Summary of the Utility Model

[0005] Based on the above problems, the purpose of the present utility model is to provide a faucet that can effectively reduce the industry support field, reduce the production process, reduce the dependence on large-scale production equipment during production, thereby reducing the production cost, and at the same time ensuring the aesthetic appearance.

[0006] In view of the above problems, the following technical solution is provided: A faucet includes a cylinder formed by cutting a tubular profile. An outlet arm extending in the radial direction of the cylinder is provided at the upper end of the cylinder, and a water outlet nozzle is provided on the outlet arm. A bottom plate welded and fixed to the inner wall of the cylinder is provided on the inner wall of the cylinder below the outlet arm. The bottom plate is provided with a water inlet hole, and a water inlet pipe connected to the water inlet hole and extending towards the bottom of the cylinder is welded to the bottom plate. An outlet cavity is formed between the upper part of the bottom plate and the inner cavity of the outlet arm. A mounting cylinder extending downward into the outlet cavity is provided on the upper surface of the outlet arm corresponding to the upper end of the cylinder. A valve core is further included. The valve core passes through the mounting cylinder, and the water inlet at the bottom of the valve core abuts and seals with the water inlet hole. The water outlet of the valve core is arranged with a gap from the upper surface of the bottom plate or is located on the side wall of the valve core to communicate with the outlet cavity. A first sealing ring is provided between the outer wall of the valve core and the inner wall of the mounting cylinder.

[0007] In the above structure, the valve core is a side-outlet valve core or a bottom-outlet valve core (prior art); for the side-outlet valve core, a water inlet is provided at the lower end and a water outlet is provided at the side. The water inlet abuts against the bottom plate to ensure sealing, and the water outlet directly discharges water into the outlet cavity from the side of the valve core.

It can save more materials and reduce weight, effectively reducing the thickness of the water distribution components at the lower end of the valve core (the thickness can be reduced to no more than 2 mm), and at the same time, it can effectively increase the height of the outlet arm to make the whole more beautiful.

[0008] The present utility model is further configured such that the bottom plate includes an outer edge formed by stamping and stretching. The outer edge extends towards the bottom of the cylinder, and the junction between the outer edge and the bottom plate is welded to the inner wall of the cylinder and / or the lower end of the outer edge is welded to the inner wall of the cylinder.

[0014] The present utility model is further configured such that the upper end of the installation cylinder is provided with a gland that is threadedly engaged with the inner wall of the installation cylinder, and the valve core is pressed onto the bottom plate by the gland.

[0015] In the above structure, the inner wall of the upper end of the installation cylinder is threaded; the inner wall of the lower end is smooth, which is used to be hermetically fitted with the first sealing ring to prevent water from leaking out of the water outlet cavity.

[0016] The present utility model is further configured such that the outer edge of the water inlet of the valve core is provided with a second sealing ring, and the second sealing ring is in contact with the upper surface of the bottom plate.

[0017] In the above structure, the valve core is pressed onto the bottom plate by the gland, so that the second sealing ring is in contact with the bottom plate for sealing, preventing water from leaking.

[0021] The present utility model is further configured such that one end of the extension section in the extending direction is closed, and the water outlet nozzle is located on the lower surface of the extension section in the extending direction.

[0022] The present utility model is further configured to further include a handle connected to the valve stem of the valve element.
