Description

Technical Field

[0001] This invention relates to a valve seat structure and its manufacturing method, and a faucet structure and its manufacturing method, particularly to a valve seat structure and its manufacturing method in which the cold water circuit, hot water circuit, and mixing water circuit are all integrally formed with the main body. Background Technology

[0002] Existing faucet structures consist of a top-sealed valve core housed within a valve seat structure connected to a cold water pipe and a hot water pipe. The valve core's flow rate is controlled by a lever, allowing the cold and hot water to mix within the housing to create warm water, which is then dispensed from a spout for user washing. An O-ring is typically used to seal the valve core and valve seat to prevent water leakage through the gap. However, since these faucet structures are manufactured using a machining process... However, machining processes often leave slight errors, which can lead to poor tolerances and water leakage problems. Furthermore, after prolonged use, the O-ring of the faucet may age, resulting in insufficient sealing and allowing water to leak out from the gap between the valve core and the valve seat. Therefore, how to effectively solve the water leakage problem caused by the tolerance between components or the long-term use of the valve core through innovative hardware design, so as to truly achieve the goal of water conservation, is a challenge that developers and researchers in the faucet structure and related industries need to continuously strive to overcome and solve.

This is achieved through a hardware design that drills holes into the main body to allow the three water paths to be integrally formed with a main body made of stainless steel, brass, plastic steel, alloy, or ceramic. Combined with the water outlet, water flows from the annular water path surrounding the main body.

The handle cover 22 is sleeved on the control handle 211 of the valve core 21 to control the control handle 211, thereby controlling the mixing ratio of cold water in the first water passage 121 and hot water in the second water passage 122. The handle cover 22 extends into a handle 221 to make it easier for the user to operate the handle cover 22 and the valve core 21.

[0107] In addition, please refer to it again. Figure 9 and Figure 10 As shown, the water outlet pipe 14 disposed outside the water outlet 131 can be, for example, but not limited to, a circular or flat shape, so that water mixed from the cold water of the first water passage 121 and the hot water of the second water passage 122 can be discharged from the water outlet pipe 14 without affecting the actual implementation of the present invention.

[0108] In addition, please see Figure 11 The diagram shown is a flowchart illustrating the manufacturing process of a faucet structure with a valve seat according to the present invention. The manufacturing process of the faucet structure with a valve seat includes the following steps:

[0109] Step S1: A first receiving space 111 is formed at one end of a body 11 by a milling and turning technique, and an annular groove is formed outside the first receiving space 111, wherein an inner tube wall 113 is formed between the annular groove and the first receiving space 111; wherein the milling and turning technique is a technique of using a CNC milling and turning device to perform lathe and milling machine operation.

[0110] Step 2 S2: A water channel assembly 12 is formed in the first accommodating space 111 in a direction away from the first accommodating space 111. The water channel assembly 12 is formed by drilling a first water channel 121, a second water channel 122, and a first mixed water channel 123, wherein the first water channel 121, the second water channel 122, and the first mixed water channel 123 are exposed in the first accommodating space 111.

[0111] Step 3 S3: A second mixing channel 124 is formed by drilling from the annular groove toward the first mixing channel 123, wherein the second mixing channel 124 is connected to the first mixing channel 123.

[0112] Step 4 S4: An outer pipe wall 13 is provided around the annular groove to form an annular water channel 112, wherein the outer pipe wall 13 is welded around the annular groove; further, the welding method can be any one of gas welding, resistance welding, arc welding, induction welding, laser welding, spot welding, seed welding, etc., and is not limited thereto.

[0113] Step 5 S5: Form an outlet 131 by drilling a hole in the outer pipe wall 13.

[0114] Step S6: After the outlet 131 is formed, a water outlet pipe 14 is further installed around the outlet 131 by welding. Further, the welding method can be any one of gas welding, resistance welding, arc welding, induction welding, laser welding, spot welding, or seed welding, and is not limited thereto. In addition, after the outlet 131 is formed, a water outlet pipe 14 is further installed at the outlet 131 by laser welding so that the mixed water flowing out of the outlet 131 can flow out through the water outlet pipe 14. Please refer to [further details]. Figure 9 and Figure 10 As shown, the water outlet pipe 14 disposed outside the water outlet 131 can be, for example, but not limited to, a circular or flat shape, and can achieve the purpose of discharging the mixed water through the water outlet pipe 14 without affecting the actual implementation of the present invention.

[0115] Furthermore, in step seven S7: after the water outlet pipe 14 is formed, a surface polishing process is performed on the body 11, the outer pipe wall 13 and the water outlet pipe 14 to perform the surface polishing action.

[0116] Furthermore, after the surface polishing process, a valve core 21 with a control handle 211 is disposed within the first accommodating space 111; please refer again. Figure 5 and Figure 9 As shown, the body 11 of the valve seat structure 1 has at least two positioning holes 116, which are exposed in the first accommodating space 111. The valve core 21 is provided with two corresponding positioning members that engage with the positioning holes 116. The valve core 21 can be assembled in the first accommodating space 111 of the valve seat structure 1 by means of the positioning members engaging with the positioning holes 116. In addition, the control handle 211 can control the mixing ratio of cold water from the first water passage 121 and hot water from the second water passage 122, so that the mixed water of cold water and hot water is discharged from the outlet pipe 14.

[0117] Furthermore, a handle cover 22 with a handle 221 is fitted onto the control handle 211 of the valve core 21; please refer to the following: Figure 10 As shown, the handle cover 22 is sleeved on the control handle 211 of the valve core 21 to control the control handle 211, thereby controlling the mixing ratio of cold water in the first water channel 121 and hot water in the second water channel 122. The handle cover 22 extends into a handle 221 to make it easier for the user to operate the handle cover 22 and the valve core 21.

[0118] As can be seen from the above description, compared with the prior art and products, the valve seat structure and manufacturing method of the present invention and the faucet structure and manufacturing method of the present invention have the following advantages:

[0119] The valve seat structure and manufacturing method of the present invention, as well as the faucet structure and manufacturing method, mainly utilize a hardware design that drills holes to set the cold water path, hot water path, and hot and cold water mixing path within the main body. This allows the three water paths to be integrally formed with any type of main body, such as stainless steel, copper, plastic steel, alloy, or ceramic. Combined with the water outlet, water flows out from the annular water path surrounding the main body. This effectively solves problems such as water leakage caused by tolerances between components or long-term use of the valve core. It truly achieves the main advantages of avoiding water leakage and effectively saving water, and eliminating the need for gaskets to avoid poor sealing after aging.
