Description

Technical Field

[0001] This utility model relates to the field of faucet technology, specifically to a split-type faucet. Background Technology

[0002] A faucet is a common name for a water valve, used to control the flow of water and thus saving water. Due to their complex shapes, faucets are often manufactured using casting, a process that allows for the production of complex shapes with high efficiency. Die casting and other similar processes allow for rapid replication after mold completion, and unit costs decrease significantly with increasing production volume, making them suitable for large-scale orders.

[0003] However, problems such as porosity, shrinkage cavities, or slag inclusions are prone to occur during the casting process, which can lead to insufficient pressure bearing capacity of the faucet and result in low product quality. Furthermore, after casting and demolding, sand removal treatment is required to form the internal pipes of the faucet, making the manufacturing process complex. Utility Model Content

[0004] The purpose of this utility model is to provide a split-type faucet in response to the defects and deficiencies of the existing technology.

[0005] To achieve the above objectives, the present invention adopts the following technical solution: a split-type faucet, comprising a faucet housing, a water outlet cavity formed at one end of the faucet housing, a water inlet cavity formed at the other end of the faucet housing, a valve core cavity formed on the faucet housing between the water outlet cavity and the water inlet cavity, a water inlet pipe slidably disposed at the other end of the faucet housing within the water inlet cavity, a valve core seat disposed on the water inlet pipe and corresponding to the position of the valve core cavity, and a valve core hole opened on the valve core seat and communicating with the water inlet pipe, the valve core hole communicating with the water outlet cavity.

[0006] A further improvement is that the faucet housing is composed of two separate pieces, with the two pieces forming an outlet chamber, an inlet chamber, and a valve core chamber.

[0007] A further improvement is that both pieces are integrally molded.

[0008] A further improvement is that a limiting boss is provided on the water inlet pipe.

[0009] A further improvement is that a valve seat limiting block is provided on the faucet housing.

[0010] A further improvement is that one end of the faucet housing is provided with a water outlet threaded surface, which is located on the outer surface of the faucet housing.

[0011] A further improvement is that a valve core thread surface is provided on the faucet housing inside the valve core cavity.

[0012] A further improvement is that the water inlet pipe is provided with a connecting threaded surface.

[0013] A further improvement is that the water inlet pipe is fixed to the other end of the faucet housing by welding.

[0014] A further improvement is that the two pieces are fixed together by welding to form the faucet shell.

[0015] The beneficial effects of this utility model after adopting the above technical solution are as follows: When manufacturing a faucet, the faucet body is divided into two halves. The two halves are manufactured by stamping, extrusion or mold forming. The inlet pipe, valve core seat and valve core hole are then manufactured by cold heading or machine tool processing. During assembly, the two halves are simply joined and welded together to form a complete faucet body. The inlet pipe is then pushed in from the inlet cavity so that the valve core seat and valve core hole correspond to the valve core cavity. The inlet pipe is then welded to the other end of the faucet body. The separate production method can reduce the problems of porosity, shrinkage cavities or slag inclusions that are prone to occur in casting processing, and it is less likely to cause insufficient pressure bearing of the faucet and low product quality. The internal pipes of the faucet can be formed without desanding treatment. The manufacturing process is simple and can reduce the manufacturing cost of the faucet.

[0016] Further effect: When the valve core body is installed in the valve core cavity, the lower end face of the valve core body abuts against the upper end face of the valve core seat. At this time, the valve core hole is connected to the water inlet hole of the valve core body, and the water flow can be controlled to flow out of the water outlet cavity through the valve core body.

[0017] Further effects: The two pieces are joined together by clamps or molds, and then the mold joint line between the two pieces is welded and fixed by welding machines or manual labor.

[0018] Further effects: After the water inlet pipe is inserted into the faucet housing from the water inlet cavity and the water inlet pipe moves to the position corresponding to the valve core seat and valve core cavity, the limiting boss can restrict the water inlet pipe from moving further inward, thereby achieving the function of the valve core seat and valve core cavity being aligned. After the limiting action is completed, the welding position can be positioned by welding between the limiting boss and the other end of the faucet housing.

[0019] Further benefits: When the water inlet pipe is inserted into the faucet housing from the water inlet chamber and the valve core seat corresponds to the valve core chamber, the valve seat limiting block can restrict the water inlet pipe from driving the valve core seat to rotate, preventing the valve core seat from tilting and affecting the installation and sealing effect of the valve core body, thus playing the positioning role of the valve seat limiting block.

[0020] Further benefits: After the water inlet pipe is fixed to the other end of the faucet housing with a clamp, the contact points are then welded together by machine or manually. Welding not only fixes the water inlet pipe to the faucet housing, but also prevents water from leaking out from the gap between the water inlet pipe and the faucet housing.

[0030] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0031] See Figures 1 to 7As shown, the technical solution adopted in this specific embodiment is: a split-type faucet, including a faucet housing 1, a water outlet cavity 2 formed at one end of the faucet housing 1, a water inlet cavity 3 formed at the other end of the faucet housing 1, a valve core cavity 4 formed on the faucet housing 1 between the water outlet cavity 2 and the water inlet cavity 3, a water inlet pipe 5 slidably disposed at the other end of the faucet housing 1 within the water inlet cavity 3, a valve core seat 6 disposed on the water inlet pipe 5 and corresponding to the position of the valve core cavity 4, and a valve core hole 7 opened on the valve core seat 6 and communicating with the water inlet pipe 5, the valve core hole 7 communicating with the water outlet cavity 2. The outer wall of the water inlet pipe 5 is clearance-fitted with the water inlet cavity 3 on the inner wall of the faucet housing 1.

[0032] The water outlet chamber 2, water inlet chamber 3, and valve core chamber 4 are all interconnected. The water inlet pipe 5, valve core seat 6, and valve core hole 7 are integrally formed by cold heading process, or the water inlet pipe 5 is processed by CNC machine tool, and then the valve core seat 6 and valve core hole 7 are cut to form the water inlet pipe 5, valve core seat 6, and valve core hole 7.

[0033] The faucet housing 1 is composed of two separate pieces, with the water outlet chamber 2, water inlet chamber 3, and valve core chamber 4 formed between the two pieces. Figure 1 As shown, the faucet housing 1 is divided into left and right parts, and the water inlet pipe 5 slides back and forth within the water inlet chamber 3. When the faucet housing 1 is not divided into parts, it is manufactured by methods such as cold heading, machine tool processing, or integral molding.

[0034] Both pieces are integrally molded. The faucet housing 1 is formed by splicing two pieces, both of which are formed by stamping, extrusion, or mold demolding. The two pieces are symmetrically arranged.

[0035] A limiting boss 8 is provided on the water inlet pipe 5. The diameter of the limiting boss 8 is larger than the diameter of the water inlet cavity 3. The limiting boss 8 can be a hexagonal boss, which makes it easy to use a wrench to tighten the faucet for installation.

[0036] The faucet housing 1 is provided with a valve seat limiting block 9. There are two valve seat limiting blocks 9, which are respectively set on two plates. The valve seat limiting blocks 9 are integrally formed with the plates, or the valve seat limiting blocks 9 are welded to the plates after the plates are stamped. Alternatively, only one valve seat limiting block 9 may be provided, and it may be set on only one of the plates. The setting position of the valve seat limiting block 9 is offset from the installation position of the valve core body after it is installed in the valve core cavity 4, so as to prevent the valve seat limiting block 9 from interfering with the installation position of the valve core body.

[0037] One end of the faucet housing 1 is provided with a water outlet threaded surface 10, which is located on the outer surface of the faucet housing 1.

[0038] The faucet housing 1 has a valve core thread surface 11 located inside the valve core cavity 4. After the faucet housing 1 is formed by welding two pieces together, the water outlet thread surface 10 and the valve core thread surface 11 are processed by a thread processing device.

[0039] The water inlet pipe 5 is provided with a connecting thread surface 12. The connecting thread surface 12 is processed by a thread processing device during the production of the water inlet pipe 5.

[0040] The water inlet pipe 5 is fixedly connected to the other end of the faucet housing 1 by welding.

[0041] The two pieces are fixed together by welding to form the faucet shell 1.

[0042] The working principle of this utility model is as follows: When manufacturing a faucet, the faucet body 1 is divided into two halves. The two halves are manufactured by stamping, extrusion or mold forming. The water inlet pipe 5, valve core seat 6 and valve core hole 7 are then manufactured by cold heading or machine tool processing. During assembly, the two halves are simply joined and welded together to form a complete faucet body 1. The water inlet pipe 5 is then pushed in from the position of the water inlet cavity 3 so that the valve core seat 6 and valve core hole 7 correspond to the valve core cavity 4. The water inlet pipe 5 is then welded and fixed to the other end of the faucet body 1. The split production method can reduce the problems of porosity, shrinkage cavities or slag inclusions that are easy to occur in casting processing, and it is less likely to cause insufficient pressure bearing of the faucet and low product quality. The internal pipeline of the faucet can be formed without desanding treatment. The manufacturing process is simple and can reduce the manufacturing cost of the faucet.

[0043] When the valve core body is installed in the valve core cavity 4, the lower end face of the valve core body abuts against the upper end face of the valve core seat 6. At this time, the valve core hole 7 is connected to the water inlet hole of the valve core body, and the water flow can be controlled to flow out of the water outlet cavity 2 through the valve core body.

[0044] The two pieces are positioned and joined together using a clamp or mold equipment, and then the mold joint line between the two pieces is welded and fixed by a welding machine or manually.

[0045] After the water inlet pipe 5 is inserted into the faucet housing 1 from the position of the water inlet chamber 3, and the water inlet pipe 5 moves to the position corresponding to the valve core seat 6 and the valve core cavity 4, the limiting boss 8 can restrict the water inlet pipe 5 from moving further inward, thereby achieving the function of the valve core seat 6 and the valve core cavity 4 corresponding to each other. After the limiting action is completed, the welding position can be positioned by welding between the limiting boss 8 and the other end of the faucet housing 1.

[0046] When the water inlet pipe 5 is inserted into the faucet housing 1 from the position of the water inlet chamber 3, and the valve core seat 6 corresponds to the position of the valve core cavity 4, the valve seat limiting block 9 can restrict the water inlet pipe 5 from driving the valve core seat 6 to rotate, preventing the valve core seat 6 from tilting and affecting the installation and sealing effect of the valve core body, and can play the positioning role of the valve seat limiting block 9.

[0047] After the water inlet pipe 5 is fixed to the other end of the faucet housing 1 with a clamp, the contact end is welded and fixed by machine or manually. After welding, not only can the water inlet pipe 5 be fixed to the faucet housing 1, but water can also be prevented from flowing out from the gap between the water inlet pipe 5 and the faucet housing 1.
