Description

Technical Field

[0001] This utility model belongs to the field of faucet technology, and specifically refers to a bathroom faucet. Background Technology

[0002] In the bathroom industry, traditional faucets have many design flaws during long-term use, especially in installation and subsequent maintenance, which affect product lifespan and user experience.

[0003] Because the rear of the main body is usually designed with a large cavity structure to accommodate the valve core and connecting pipes, a large locking force needs to be applied during installation, along with the pressure cap used to fix the faucet body, to ensure that the faucet is stable on the countertop or wall. When used for a long time or when the locking force is too large, the rear shell of the main body is prone to irreversible plastic deformation. This deformation can affect the seal around the valve core, causing leakage or dripping at the connection between the valve core and the main body, thereby accelerating the corrosion of the hardware and the growth of mold.

[0004] In addition, because the rear of the faucet body is usually tightly fitted to the wall or mounted with a back panel, it forms a relatively enclosed and poorly ventilated narrow space. During daily use, moisture can easily seep into the cavity through the gaps. Once water accumulates, it is difficult to drain naturally, and the damp, enclosed environment is more likely to breed bacteria and mold, while also causing irreversible corrosion to the valve core. Utility Model Content

[0005] The purpose of this utility model is to provide a bathroom faucet that can enhance the overall stability of the faucet by utilizing a unique main structure, while also achieving the ability to actively prevent water accumulation by opening a drainage groove.

[0006] The purpose of this utility model is achieved as follows:

[0007] A bathroom faucet includes a faucet body with a valve core control end and a water outlet, and a cavity with a rear opening is formed at the rear end of the faucet body. A back plate is provided at the rear end of the faucet body to seal the rear opening. The back plate has a water inlet for connecting a water inlet pipe. A valve core assembly is provided in the cavity. The cavity includes an upper cavity wall and a lower cavity wall. A support column is provided between the upper cavity wall and the lower cavity wall.

[0008] The present invention is further configured such that a stepped groove for embedding the back plate is formed on the inner wall of the rear opening, a drainage side groove is provided on the lower groove wall of the stepped groove, and a drainage hole is provided on the back plate. When the back plate is placed on the rear opening, the edge of the rear end face of the back plate abuts against the bottom of the stepped groove, the bottom of the rear end face of the back plate forms a drainage groove with the drainage side groove, and the drainage hole is connected to the drainage groove.

[0009] The present invention is further configured such that there are two water inlets, which are respectively opened at both ends of the back plate; the valve core assembly includes a valve core seat; the water inlet pipe includes a cold water pipe and a hot water pipe respectively connected to both ends of the valve core seat; the ends of the cold water pipe and the hot water pipe extend out of the two water inlets; and there are two support columns, which are located on both sides of the valve core seat.

[0010] The present invention is further configured such that the side of the support column near the cavity is formed with a support rounded corner for supporting the hot water pipe or cold water pipe, and both ends of the valve core seat are provided with sockets for inserting the cold water pipe or hot water pipe, and the edges of the sockets are provided with installation chamfers.

[0011] The present invention is further configured such that the valve core control end includes an installation port opened at the upper middle part of the faucet body, the upper end of the valve core seat is connected to a valve core extending out of the installation port, and a pressure cap is screwed into the installation port, the bottom of the pressure cap abutting against the top of the valve core.

[0027] The present invention will be further described below with reference to the accompanying drawings and specific embodiments. See also: Figure 1 — Figure 4 :

[0028] A bathroom faucet includes a faucet body 1 having a valve core control end 10 and a water outlet 11. The rear end of the faucet body 1 forms a cavity with a rear opening 12. The rear end of the faucet body 1 is covered with a back plate 2 that seals the rear opening 12. The back plate 2 has an inlet 20 for connecting a water inlet pipe. A valve core assembly 3 is disposed in the cavity. The cavity includes an upper cavity wall 40 and a lower cavity wall 41. A support column 4 is disposed between the upper cavity wall 40 and the lower cavity wall 41.

[0029] During implementation, regardless of whether the faucet body is made of plastic or metal, by setting a simple support column 4 between the upper cavity wall 40 and the lower cavity wall 41, the structural strength of the cavity on the rear side of the faucet body is effectively improved, preventing deformation of the cavity and avoiding sealing loss due to deformation of internal components. This solves the problem of leakage or dripping at the valve core connection after the pressure cap is locked.

[0030] In addition, the aforementioned lack of sealing usually refers to problems such as O-rings or gaskets not sealing properly after deformation.

[0031] It is worth mentioning that the supporting column 4, the upper cavity wall 40, and the lower wall 41 are integrally formed, thereby further improving the overall structural strength.

[0032] Preferably, a stepped groove 120 for fitting the back plate 2 is formed on the inner wall of the rear opening 12. A drainage side groove 121 is provided on the lower groove wall of the stepped groove 120, and a drainage hole 21 is provided on the back plate 2. When the back plate 2 is placed on the rear opening 12, the edge of the rear end face of the back plate 2 abuts against the bottom of the stepped groove 120, and the bottom of the rear end face of the back plate 2 forms a drainage groove with the drainage side groove 121. The drainage hole 21 is connected to the drainage groove.

[0033] In the above structure, the drainage channel is formed by the gap between the bottom of the back plate and the drainage side channel after the back plate is closed, thereby efficiently draining the water that has seeped into or condensed in the cavity.

[0034] Typically, the back plate 2 abuts against the bottom of the stepped groove 120 by covering it. After covering, since the drainage side groove 121 extends further into the cavity, the bottom of the rear end face of the back plate will form a drainage groove that can merge with the drainage side groove.

[0035] Preferably, there are two water inlets 20, which are respectively opened at both ends of the back plate 2. The valve core assembly 3 includes a valve core seat 30. The water inlet pipe includes a cold water pipe 31 and a hot water pipe 32 that are respectively connected to both ends of the valve core seat 30. The ends of the cold water pipe 31 and the hot water pipe 32 extend out of the two water inlets 20. There are two support columns 4, which are located on both sides of the valve core seat 30.

[0036] Preferably, the support column 4 has a support rounded corner 42 formed on the side near the cavity for supporting the hot water pipe 32 or the cold water pipe 31, and the valve core seat 30 has a socket 33 at both ends for inserting the cold water pipe 31 or the hot water pipe 32, and the edge of the socket 33 is provided with an installation chamfer 34.

[0037] During the above implementation process, the sidewalls of the cold water pipe 31 and the hot water pipe 32 can make large-area contact with the support fillet 42, which not only enhances the support capacity for the cold and hot water pipes, but also prevents the edge of the support column from wearing down the sidewalls of the water pipes.

[0038] In addition, the support fillet and the support column are integrally formed to ensure a certain structural strength.

[0039] Preferably, the valve core control end 10 includes an installation port 13 located at the upper middle part of the faucet body 1, and the upper end of the valve core seat 30 is connected to a valve core 35 extending out of the installation port 13. A pressure cap 14 is screwed into the installation port 13, and the bottom of the pressure cap 14 abuts against the top of the valve core 35.

[0040] Preferably, there are two sets of drainage side channels 121, and the two sets of drainage side channels 121 are arranged symmetrically from left to right. Two drainage holes 21 are opened on the rear end face of the back plate 2.

[0041] In the above structure, two sets of symmetrical drainage side channels are used to form two sets of symmetrical drainage troughs, which can improve drainage efficiency. During implementation, the stepped groove is set between the two sets of drainage side channels, that is, after the back plate is covered, two independent drainage troughs can be formed, further improving drainage efficiency.

[0042] In addition, the structure of this faucet is not only suitable for ordinary shower faucets, but also for bathtub faucets, that is, a lifting water divider is set between the valve core seat and the water outlet to realize the basic function of a bathtub faucet.

[0043] The above embodiments are merely preferred embodiments of this utility model and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape, and principle of this utility model should be included within the scope of protection of this utility model.
