Description

Technical Field

[0001] This utility model relates to the field of bathroom faucets, specifically to a faucet body. Background Technology

[0002] Existing faucets are generally made from a single piece of material through drilling or sand casting, which results in drawbacks such as heavy weight and high material and processing costs. Therefore, with continuous optimization and improvement, faucets with a water distribution core installed in a thin shell have begun to appear on the market, effectively reducing weight and significantly lowering material and processing costs. However, during production, the water distribution core needs to be adapted to the shell, resulting in a one-to-one fit and low versatility. If the water distribution core needs to be adapted to shells of different shapes, the water distribution core structure needs to be readjusted to achieve the desired fit. For example, injection-molded water distribution cores require multiple molds or mold modifications, increasing mold opening costs. Utility Model Content

[0003] Based on the above problems, the purpose of this utility model is to provide a faucet body that is easy to assemble and can be adapted to different cross-sectional shapes and housings without changing the size of the water distribution core structure.

[0004] To address the above problems, the following technical solution is provided: A faucet body includes a water distribution core and a housing located outside the water distribution core. The top of the housing has a through hole, and the side wall of the housing has a side hole. The water distribution core has, from bottom to top, a lower support that is adapted to and centered at the lower end of the housing, a valve core contact position corresponding to the side hole, and an upper branch pipe passing through the through hole. The valve core contact position has an inlet channel connected to the bottom of the lower support and an outlet channel connected to the bottom of the lower support or the upper branch pipe. The valve core contact position also has a valve core mounting sleeve that is threaded and fixed to it and passes through the side hole, and constrains the water distribution core in the axial and circumferential directions within the housing. The exposed end of the valve core mounting sleeve has a pressure cap thread.

[0005] The present invention is further configured such that the outer side of the valve core contact position is provided with an external thread; the end of the valve core mounting sleeve away from the gland thread is provided with a connecting internal thread that engages with the external thread.

[0006] The present invention is further configured such that the gland thread is located on the inner wall of the valve core mounting sleeve; the outer wall of the end of the valve core mounting sleeve with the gland thread is provided with an engagement groove / hole.

[0007] The present invention is further provided that the water distribution core is also provided with a pull-out channel that is connected vertically through the upper branch pipe.

[0008] The present invention is further configured such that the outer wall of the exposed portion of the upper branch pipe through the through hole is provided with an anti-detachment groove, and the anti-detachment groove is provided with a C-shaped connecting bushing.

[0009] The present invention is further configured such that the inner wall of the through hole is provided with a first engaging part; the outer wall of the upper branch pipe is provided with a lower shoulder that abuts against the inner wall of the housing at the lower end of the through hole, and a second engaging part that engages with the first engaging part is provided above the lower shoulder.

[0010] The present invention is further configured to include a centering gasket, wherein the centering gasket has a meshing hole at its center and a first meshing part is provided on the inner wall of the meshing hole; the outer wall of the upper branch pipe has a lower shoulder and a second meshing part is provided above the lower shoulder; the centering gasket is inserted from the lower end of the housing along with the water distribution core and reaches the upper end of the housing cavity to abut against the inner wall of the upper end of the housing cavity, while the outer edge of the centering gasket abuts against the side wall of the upper end of the housing cavity for centering.

[0011] The present invention is further configured such that the cross-section of the shell and / or the cross-section of the upper end of the inner cavity is circular, polygonal, or non-rotational; the cross-section of the upper end of the inner cavity of the shell is equal to or smaller than the cross-section of the shell.

[0012] The present invention is further configured such that the water inlet channel is divided into two groups, namely a hot water channel and a cold water channel.

[0013] The present invention is further configured to include a control valve placed inside the valve core mounting sleeve, the bottom of which abuts against the valve core and is connected to the inlet and outlet water channels; the gland is threaded with a gland that abuts against the control valve for fixing the control valve.

[0014] The present invention is further configured such that a decorative sleeve is fitted on the outer wall of the valve core mounting sleeve, and the decorative sleeve is fixed by a pressure cap or a decorative cover screwed onto the pressure cap against its end face.

[0015] The beneficial effects of this utility model are: 1. The housing only needs to ensure that the bottom fits the lower support, the top fits the upper branch pipe, and the side holes correspond to the valve core contact points. After the water distribution core is placed into the housing, it is fixed by the valve core mounting sleeve. This ensures that the housing shape, whether square, round, or drum-shaped, does not affect the compatibility and installation with the water distribution core. Therefore, only one type of water distribution core needs to be produced to achieve compatibility with housings of different shapes, resulting in good versatility and effectively reducing production costs. The water outlet is connected to the upper branch pipe, and water can be discharged from the top after the water outlet support arm is connected to the upper branch pipe. Alternatively, the water outlet can be connected to the bottom of the lower support. The water outlet can be connected to a pull-out hose. The pull-out hose goes down and then goes up in the opposite direction to install the counterweight before passing through the upper branch pipe, which is suitable for pull-out faucets. 2. After the water distribution core is inserted into the housing, the valve core mounting sleeve is inserted into the side hole and screwed into the external thread of the valve core contact position to complete the installation; the water distribution core and valve core mounting sleeve are preferably injection molded; 3. The C-shaped connecting bushing is used to connect the outlet support arm or the pull-out support arm; the lower end of the C-shaped connecting bushing also abuts against the top surface of the shell, which helps to axially constrain the exposed part of the upper branch pipe. 4. Both the first and second meshing parts are toothed structures. While performing centering, their meshing helps to improve the circumferential constraint effect between the water distribution core and the shell; suitable for shells with a narrower upper end. 5. Auxiliary support is provided by centering shims. Different shaped centering shims can be replaced when adapting to different cross sections, so that the water distribution core can be adapted to shells of different shapes without modifying the mold. While providing centering, it can also achieve circumferential constraint between the shell and the water distribution core for shells with non-rotational cross sections. 6. After the control valve is fixed by the gland, part of its threaded structure is exposed for the installation of a decorative cover. The decorative cover and the decorative sleeve are pressed together to fix the decorative sleeve, which is used to cover the valve core and improve its appearance. Attached Figure Description
