However, this design is only suitable for integrated modules where the outlet of the water inlet channel and the inlet of the water outlet channel are on the same plane. For example, the three through holes 171 (leading to the cold water pipe 11, hot water pipe 12 and mixing chamber 13) on the mixing valve core seat 17 in patent CN201410275356.6 are integrated.

However, there are great difficulties in processing, precision sealing and assembly. Therefore, the following patent is designed to overcome the technical difficulties of sealing stainless steel pipes during assembly, and to effectively utilize low-cost stainless steel materials.

[0044] In this embodiment, the cold, hot water inlet pipe, mixed water outlet pipe, valve core shell 24, faucet shell 4 are all made of stainless steel material. In actual application, since the stainless steel pipe is easy to form and has very low cost, when the pipe end of the cold, hot water inlet pipe is directly inserted into the longitudinal sealing hole 221 of the three-dimensional special-shaped sealing ring 22 and then inserted into the sealing through cavity 23, the pipe end generates extrusion force on the longitudinal sealing hole 221, so that the longitudinal sealing hole 221 and the longitudinal deep through hole 211 are more tightly matched. Especially, the sealing through cavity 23 is a sealing passage with longitudinal depth, so that the pipe end of the cold, hot water inlet pipe inserted therein has a certain longitudinal redundant movement space. Inserting shallowly or deeply does not affect the sealing and through effect. Based on the structural principle, when the stainless steel material is used, the advantages of low cost and high water quality of the stainless steel can be utilized, and the stainless steel material which is not easy to realize sealing assembly is allowed. Reverse thinking allows a certain range of sliding in use while ensuring the sealing effect, so that the technical difficulty of the stainless steel material being difficult to apply in the field is broken through. Of course, even if the patent structure is not based on the stainless steel material but based on other materials, the assembly flexibility, simple mold and cost reduction and other technical advantages are realized, which greatly meets the use requirements of various ranges in the field.

[0045] The above embodiments and drawings do not limit the product shape and style of the utility model. Any appropriate changes and modifications made by ordinary skilled persons in the art shall be considered as not departing from the scope of the utility model.
