Description

Technical Field

[0001] The utility model relates to the technical field of bathrooms, in particular to a faucet. Background Art

[0002] Faucets are common bathroom products in daily life. A valve core seat is provided inside the faucet housing. The valve core seat is provided with a valve core to control the water outlet. The mixed water flows out from the side outlet of the valve core seat, then flows into the outlet pipe of the faucet housing, and finally flows out from the end of the outlet pipe. A connecting port connected to the outlet pipe is provided inside the faucet housing. In order to ensure the sealing of the side outlet of the valve core seat and the connecting port on the faucet housing, a sealing ring is often provided on the periphery of the side outlet. Moreover, the currently popular faucet shape sets the root of the outlet pipe close to the top of the faucet housing, so that the height of the connecting port is higher than the side outlet position of the valve core seat after installation, and the sealing of the periphery of the side outlet needs to be set into a runway shape (or a rounded rectangle). By setting an inclined surface between the valve core seat and the faucet housing, the sealing ring can be pressed tightly when the valve core seat is installed.

[0003] In order to solve the above problems, the inventor of this case has proposed a faucet structure (CN220688077U), which was published on March 29, 2024. The valve core seat is installed into the faucet shell from top to bottom to achieve the positioning of the valve core seat and support for the arc block. However, due to the presence of the limiting bottom plate in the faucet shell, the inner cavity of the faucet shell needs two upper and lower modules to be formed, which increases the cost of the mold and the difficulty of processing.

[0004] In view of this, the inventor conducted in-depth research on the above-mentioned defects in the prior art, and thus came up with this case. Utility Model Content

[0005] The main purpose of the utility model is to provide a faucet, which has the characteristics of simple structure and reduced difficulty in processing the faucet shell. There is no need to set a limiting bottom plate in the middle of the faucet shell, which reduces the difficulty in processing the faucet shell.

[0006] In order to achieve the above purpose, the solution of the utility model is:

[0007] A faucet, comprising a faucet shell and a valve core seat, wherein the outer wall of the faucet shell is connected to a water outlet pipe, the faucet shell has a receiving cavity for receiving the valve core seat, and the inner wall of the receiving cavity has a connecting port connected to the water outlet pipe; an arc-shaped seat is formed on the upper part of the valve core seat, and the outer wall surface of the arc-shaped seat has a water outlet for connecting with the connecting port, and a sealing ring for abutting against the outer periphery of the connecting port is provided on the arc-shaped seat at the outer periphery of the water outlet;

[0008] Two abutting ribs are symmetrically arranged in the accommodating cavity, and a limiting slide groove is formed between the abutting ribs and the inner wall of the accommodating cavity, and the lower part of the limiting slide groove has a lower opening; the valve core seat is inserted into the accommodating cavity from bottom to top, and the two sides of the arc seat are inserted into the limiting slide groove from the lower opening upward.

[0009] Furthermore, snap-fitting holes that match the limiting sliding grooves are respectively formed on both sides of the arc-shaped seat.

[0010] Furthermore, a limit plate is formed on the valve core seat, and the bayonet extends from top to bottom to the limit plate to form a first limit notch on the limit plate, and the lower portion of the abutting rib is accommodated in the first limit notch.

[0011] Furthermore, an arc-shaped edge is formed on the top of the valve core seat, and second limiting gaps are formed between the two ends of the arc-shaped edge and the bayonet holes on both sides of the arc-shaped seat, and the lower part of the top supporting rib passes through the second limiting gap.

[0012] Furthermore, a first internal thread is formed at the upper portion of the accommodating cavity, and the upper portion of the abutting rib extends to the lower portion of the first internal thread.

[0013] Furthermore, the arc-shaped seat has cut corners on both sides of its upper portion, and the top rib has an oblique angle portion that matches the cut corners; the upper section of the oblique angle portion is connected to the lower portion of the first internal thread.

[0014] Furthermore, the lower part of the valve core seat is integrally connected with a cold water inlet pipe and a hot water inlet pipe; the top of the valve core seat is formed with a cold water inlet hole and a hot water inlet hole respectively connected to the cold water inlet pipe and the hot water inlet pipe, and the top of the valve core seat is also formed with a water outlet hole connected to the water outlet.

[0015] Furthermore, the water outlet is in a racetrack shape, and the sealing ring is a racetrack-shaped sealing ring on the outer periphery of the water outlet.

[0016] Furthermore, the faucet shell is die-casted from zinc alloy.

[0017] Furthermore, the valve core seat is injection molded from plastic material.

[0018] After adopting the above structure, the faucet involved in the utility model has at least the following beneficial effects:

[0019] First, the lower opening is set by the top rib, and the arc seat of the valve core seat is clamped from bottom to top in the limiting slide groove between the top rib and the inner wall of the accommodating cavity, so that the accommodating cavity of the faucet shell can be produced by a bottom-out mold core. The trouble of setting a limiting bottom plate in the accommodating cavity in the prior art is avoided. The processing difficulty and cost of the improved faucet shell are greatly reduced.

[0020] 2. The valve core seat is inserted from bottom to top; the abutting ribs support the arc seat so that the sealing ring on the arc seat can tightly abut against the inner wall of the accommodating cavity around the connecting port, thereby reducing deformation and water leakage of the arc seat.

[0021] 3. The bayonet on the arc-shaped seat cooperates with the limiting slide groove to make the final position between the valve core seat and the top rib more accurate, thereby reducing the relative shaking between the valve core seat and the faucet housing.

[0022] Fourth, the limit plate and the arc-shaped edge both play an auxiliary fixing role. After the valve core seat is installed in place, the limit plate and the arc-shaped edge abut against the inner wall of the accommodating cavity, so that the valve core seat is more firmly installed in the accommodating cavity of the faucet shell.

[0023] 5. The cut angle plays a guiding role, so that the two sides of the arc plate can more easily enter the limiting slide groove. The setting of the bevel portion facilitates the demoulding of the limiting slide groove, and the bevel portion cooperates with the cut angle to increase the clamping width of the upper part of the arc seat, so that it can withstand the force of the upper part of the arc seat.

[0024] Compared with the prior art, the utility model provides a limiting slide groove with a lower opening, so that the valve core seat can be installed from bottom to top, without the need to provide a traditional limiting bottom plate, thereby reducing the processing difficulty and mold cost.
