[0055] In order to make the purpose, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be described clearly and completely below in combination with the drawings in the embodiments of the present application. Obviously, the described embodiments are some of the embodiments of the present application, rather than all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative labor fall within the scope of protection of the present application. Therefore, the following detailed description of the embodiments of the present application provided in the drawings is not intended to limit the scope of the claimed present application, but only represents selected embodiments of the present application.

[0056] In the description of the present application, the terms "first", "second" are only for descriptive purposes, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of indicated technical features. Therefore, the features defined as "first", "second" can be explicitly or implicitly included one or more of the features. In the description of the present application, the meaning of "a plurality of" is two or more, unless otherwise specifically limited.

[0057] Embodiment one

[0058] A faucet body assembly, as shown in the structure Figures 1-4 It includes a mixing seat 2, a valve core seat 2-0 symmetrically arranged on both sides of the mixing seat 2, and one end of the valve core seat 2-0 is formed with a valve core socket 200, and a connecting pipe 2-00 connecting the mixing seat 2 and the valve core seat 2-0. Among them, the mixing seat 2 and the valve core seat 2-0 are metal materials such as stainless steel, copper, etc. Including but not limited to the above two kinds of metal materials, which can be selected according to actual needs.

[0059] Referring to Figure 14 , the connecting pipe 2-00 connecting the mixing seat 2 and the valve core seat 2-0; wherein the waterway of the faucet body assembly is water inlet through the water inlet of the valve core seat 2-0, adjusted through the valve core seat 2-0, then through the connecting pipe 2-00, then into the mixing seat 2, the cold and hot water of the left and right water inlets of the valve core seat 2-0 is mixed after reaching the mixing seat 2, then flows out through the mixing seat 2, and the outlet thread of the mixing seat 2 can be connected with various water outlet devices.

[0060] The water inlet hose assembly 3 includes a hose 30, a connecting end 31 arranged at the top of the hose 30, and a water inlet connector 33 arranged at the bottom of the hose 30; the connecting end 31 is clamped at the valve core socket 200; the hose 30 extends from the bottom of the valve core seat 2-0 and is connected with the angle valve through the water inlet connector 33; at least two groups of annular grooves 34 are formed on the connecting end 31, and a first sealing ring 32 for sealing is sleeved on the annular groove 34. Specifically, the first sealing ring 32 is an O-ring, and the O-ring forms an airtight or liquid-tight isolation layer between mechanical parts during use to prevent fluid or gas leakage.

[0061] Referring to Figure 13Further, the mounting of the hose 30 to the valve core seat 2-0 can be either (1) from top to bottom, or (2) from bottom to top. Both mounting methods can achieve the installation of the hose 30. However, to speed up the installation, as a preferred embodiment, the hose 30 is mounted from top to bottom, which is more convenient because the top of the valve core seat 2-0 is easier to access, and the installation of the hose 30 and the valve core can be directly from the top, without the need for additional support or complex positioning devices. This method can quickly complete the installation when space permits. When the hose 30 is mounted from bottom to top, it may be easier to access the bottom of the valve core seat 2-0 or when the top space is limited. This method may take more time to ensure that the hose 30 is correctly aligned and inserted into the correct position, especially if the bottom space is small or difficult to operate, so the efficiency is too slow. As a preferred embodiment, the hose 30 is mounted from top to bottom.

[0062] When the O-ring is installed in the sealing groove, it will be elastically deformed due to the contact compression stress on its cross-section. This deformation causes the O-ring to generate a certain initial contact pressure Po on the contact surface. This pressure is generated by the initial compression of the O-ring, and exists even in the absence of medium pressure. When the container is filled with a medium such as gas or liquid, the O-ring will be subjected to the action of the medium pressure. This pressure will cause the O-ring to displace towards the low-pressure side. At the same time, the elastic deformation of the O-ring is further increased to better fill and seal the original gap δ. With the displacement and deformation of the O-ring, the contact pressure on the contact surface of the sealing pair will increase. This final contact pressure Pm is the sum of the initial contact pressure Po and the additional contact pressure Pp caused by the medium pressure, i.e. Pm = Po + Pp, Pp is the contact pressure transmitted to the contact surface by the O-ring, and its relationship with the medium pressure P is Pp = K·P. Here K is the pressure transmission coefficient, which describes the degree to which the medium pressure is transmitted to the contact surface. For rubber O-rings, the value of K is usually 1, which means that all of the pressure of the medium is transmitted to the contact surface. When the O-ring is compressed, it will deform slightly in diameter, thereby filling the gap between the sealing surfaces and forming an effective sealing layer, effectively preventing the leakage of liquids, gases or dust.

[0063] Further, in order to ensure that the O-ring does not deform or damage during installation, and quickly and accurately install the O-ring in place, it is necessary to pay attention to the installation: before installing the O-ring, a layer of lubricant can be applied to its surface to reduce friction, making it easier to install the O-ring, and helping to improve the sealing effect.

[0064] Further, the water inlet joint 33 is a quick-release type water inlet pipe nut.

[0065] The valve core seat 2-0 includes an outer sleeve 2-1, a first water sealing ring 2-2 arranged on the lower side of the inner wall of the outer sleeve 2-1, and a threaded pipe 2-3 arranged on the lower part of the first water sealing ring 2-2.

[0066] In use, the hose 30 can be twisted off at one end of the water inlet pipe nut, and the hose 30 is inserted into the valve core seat 2-0. After the hose 30 passes out of the valve core seat 2-0, the connecting end 31 on the other end of the water inlet joint 33 is clamped by the valve core bayonet 200, thereby limiting the hose 30. The first sealing ring 32 is sleeved on the annular groove 34 and is in sealing connection with one end of the valve core seat 2-0, so that the valve body can be quickly connected with the angle valve without the need for other adapter products, and the assembly is simple and convenient.

[0067] Further, with reference to Figures 6-7 , the valve core seat 2-0 includes an outer sleeve 2-1, a first water sealing ring 2-2 arranged on the lower side of the inner wall of the outer sleeve 2-1, and a threaded pipe 2-3 arranged on the lower part of the first water sealing ring 2-2. The advantage of this arrangement is that the originally integrated valve core seat 2-0 and outer sleeve 2-1 are prepared in segments, which can greatly reduce costs. Further, the first water sealing ring 2-2 is welded to the lower side of the inner wall of the outer sleeve 2-1 by a first welding point 2-4; the threaded pipe 2-3 is welded to the lower part of the first water sealing ring 2-2 by a second welding point 2-5, and the threaded pipe 2-3 is welded to the inner wall of the outer sleeve 2-1 by a third welding point 2-6.

[0068] Wherein, the outer sleeve 2-1 is a part of the valve body, which can ensure the firm connection between the outer sleeve 2-1 and other components by welding, preventing loosening or leakage under high pressure or high flow conditions. In addition, the first water sealing ring 2-2 is usually a sealing member for preventing water leakage, which can ensure that the fluid does not leak when passing through the valve or related components. By welding the first water sealing ring 2-2 in place, it can ensure long-term effective prevention of fluid leakage. Furthermore, the threaded pipe 2-3 is similar to the outer sleeve 2-1, which is another part of the valve body or other components, used for connection with other components (here, the other components are prior art, which will not be described here). By welding, the threaded pipe 2-3 can form a stable whole structure with the outer sleeve 2-1 and the first water sealing ring 2-2. When the outer sleeve 2-1, the first water sealing ring 2-2, and the threaded pipe 2-3 are welded together, a connection point is formed between them, which not only ensures the sealing between them, but also improves the strength between them. This is because, after welding, the three form a welded joint similar to a reinforcing rib, which can ensure the strength of the entire structure.

[0069] Further, referring to Figures 10-12 , the valve core seat 2-0, the water mixing seat 2, or the valve core seat 2-0 is welded in any of the following ways:

[0070] At least one of the water inlet of the water mixing seat 2 and the water outlet of the valve core seat 2-0 is a concave cylindrical surface 2-60, and at least one end of the connecting pipe 2-00 forms a welding position with the circular arc surface 2-01 matching the cylindrical surface 2-60.

[0071] Further, the valve core seat 2-0 is placed symmetrically on the left and right ends of the water mixing seat 2, and connected together by the connecting pipe 2-00, and welded between them, i.e. the left valve core seat 2-0 is welded at the water outlet position and the left side of the connecting pipe 2-00, the right side of the connecting pipe 2-00 is welded at the left water inlet position of the water mixing seat 2, the right valve core seat 2-0 is welded at the water outlet position and the right side of the connecting pipe 2-00, and the left side of the connecting pipe 2-00 is welded at the right water inlet position of the water mixing seat 2, thus forming a faucet body group. The welding position of the valve core seat 2-0 and the water mixing seat 2 is the cylindrical surface 2-60, and the welding position of the connecting pipe 2-00 is the circular arc surface 2-01 matching the valve core seat 2-0 and the water mixing seat 2. Thus, the contact area between the valve core seat 2-0 and the water mixing seat 2 can be larger, and such welding method can provide higher welding strength and stability, optimize stress distribution, reduce stress concentration in the welding area, thereby reducing the risk of cracking and deformation, and also simplify the welding process, reduce welding time and cost, and improve production efficiency.

[0072] Way two

[0073] At least one of the water inlet of the mixing seat 2 and the water outlet of the valve core seat 2-0 is a concave cylindrical surface 2-60, and at least one end of the connecting pipe 2-00 is inserted into the cylindrical surface 2-60; and at least one end of the connecting pipe 2-00 and the arc surface 2-01 matched with the mixing seat 2 or the valve core seat 2-0 form a welding position.

[0074] Further, the welding position of the valve core seat 2-0 and the mixing seat 2 is the cylindrical surface 2-60, the connecting pipe 2-00 is inserted into the opening hole of the valve core seat 2-0 and the mixing seat 2, and the welding position is the joint position of the valve core seat 2-0 and the mixing seat 2 with the connecting pipe 2-00. At the same time, the connecting pipe 2-00 directly extends into the valve core seat 2-0 and communicates with the valve core seat 2-0, which can help to ensure the sealing of the connection and prevent liquid leakage.

[0075] Mode three

[0076] At least one of the water inlet of the mixing seat 2 and the water outlet of the valve core seat 2-0 is a stepped hole 2-62, at least one end of the connecting pipe 2-00 is inserted into the stepped hole 2-62 and abuts against the stepped hole 2-62, and at least one end of the connecting pipe 2-00 is a flat surface 2-02; and at least one end of the connecting pipe 2-00 and the stepped hole 2-62 matched with the mixing seat 2 or the valve core seat 2-0 form a welding position.

[0077] Further, the water outlet hole of the valve core seat 2-0 and the mixing seat 2 is a stepped hole 2-62 (see Figure 12 ), the connecting pipe 2-00 is inserted into the step of the opening hole of the valve core seat 2-0 and the mixing seat 2, and the welding position is the joint position of the valve core seat 2-0 and the mixing seat 2 with the connecting pipe 2-00, so that the welding area is more hidden, the interference of the external environment on the welding process is reduced, the welding quality is improved, at the same time, this connection mode can reduce the exposed area of the weld, reduce the contact opportunity of the corrosion medium, and enhance the corrosion resistance of the overall structure. In addition, due to the concealment of the welding area, the preparation work before welding such as cleaning and polishing can be reduced, thereby saving time and labor.

[0078] Further, the above three welding installation states combine the valve core seat 2-0, the mixing seat 2 and the connecting pipe 2-00, and form a faucet body.

[0079] Specifically, the above three welding states are applicable to the present case, and include but are not limited to the above three welding states, and the specific implementation can be selected according to the actual situation.

[0080] In this embodiment, the outer sleeve 2-1, the first water sealing ring 2-2, and the threaded pipe 2-3 are made of stainless steel, iron, or plastic, etc. Preferably, the outer sleeve 2-1, the first water sealing ring 2-2, and the threaded pipe 2-3 are all made of stainless steel.

[0081] Further, the connection mode of the outer sleeve 2-1, the first water sealing ring 2-2, and the threaded pipe 2-3 can be laser welding, screw locking, or one-piece forming, etc. Preferably, the connection mode of the outer sleeve 2-1, the first water sealing ring 2-2, and the threaded pipe 2-3 is laser welding.

[0082] The valve core seat can be welded and assembled by any of the following two methods:

[0083] Method one: the outer sleeve 2-1 and the first water sealing ring 2-2 are welded together by using laser welding technology. Laser welding can achieve high-precision welding and is not affected by the magnetic field, and can accurately align the welding parts. During the welding process, by controlling the parameters such as the width, energy, peak power, and repetition frequency of the laser pulse, the welding quality can be ensured. Then, one end of the threaded pipe 2-3 is laser welded with the bottom of the first water sealing ring 2-2. Since laser welding can be used for a wide range of weldable materials, it can also be used to join various heterogeneous materials, which helps to ensure the welding quality between different materials. Finally, the threaded pipe 2-3 is welded to the inner wall of the outer sleeve 2-1 through the third welding point. This step also takes advantage of the high precision and automation of laser welding to ensure the accuracy and consistency of the welding.

[0084] Method two: first, the first water sealing ring 2-2 and the threaded pipe 2-3 are laser welded together. In this step, the automation and high-speed welding characteristics of laser welding can be used to improve welding efficiency. Then, the assembled accessory formed by welding the first water sealing ring 2-2 and the threaded pipe 2-3 is laser welded with the outer sleeve 2-1. In this step, the accuracy and welding quality can be ensured by precisely controlling the focusing and movement of the laser beam. Preferably, in method two, during the welding process of the accessory and the outer sleeve 2-1, the welding head can be deepened from the top of the outer sleeve 2-1, thereby reducing the operation difficulty. This is because the overall height of the outer sleeve 2-1 is significantly smaller than that of the threaded pipe 2-3, thereby providing sufficient operating space.

[0085] Further, in method one, the welding is carried out in steps, and each welding point is welded separately, which can more accurately control the welding quality of each welding point, especially when welding the threaded pipe 2-3 with the inner wall of the outer sleeve 2-1, the positioning accuracy of the threaded pipe 2-3 can be ensured, and since the welding is carried out in steps, the welding parameters such as laser power, speed, focal point position, etc. can be optimized separately for each step to adapt to different materials and welding requirements; while in method two, the first water sealing ring 2-2 and the threaded pipe 2-3 are first welded together (including the second welding point 2-5), and then this combination is welded with the outer sleeve 2-1 (the third welding point 2-6), so as to improve the production efficiency.

[0086] Compared with the valve body made by the integral molding method on the market, the assembled and welded valve body of the present application is more cost-effective, and is also beneficial for the connection of the hose 30, allowing the hose 30 to be quickly assembled and disassembled, saving time and effort, and improving work efficiency.

[0091] Among them, the sealing ring is matched with the annular groove at one end of the water outlet connector 22, so as to seal the water outlet connector 22 and the water mixing seat 2, and further, the triple sealing is more beneficial for the use of the water outlet connector 22. Further, the three groups of sealing rings include but are not limited to three groups, which can be four groups or a plurality of groups, which can be set according to actual needs.
