[0026] Referring to the accompanying drawings of the specification, a waterway engine structure includes a housing 10. A body 20 with a plastic waterway is disposed inside the housing. The housing can be made of plastic to reduce costs. It further includes at least one water inlet joint 30 that can communicate with the body. In use, there are two water inlet joints, one for cold water and one for hot water. Similarly, the body also has two water inlets. It further includes a fixing sleeve 40 adapted to the water inlet joint. The fixing sleeve is made of metal and mainly functions to enhance the strength of the entire set of products. The number of fixing sleeves is also two, which is adapted to the number of water inlet joints. The fixing sleeve includes a metal sleeve 41 and a metal pipe 42. The metal sleeve is sleeved on the outer periphery of the water inlet 21 of the body. A metal pipe is provided on the circumferential side wall of the metal sleeve. The metal pipe can communicate with the inner circumferential side of the metal sleeve. The metal pipe is perpendicular to the axis of the metal sleeve. The water inlet joint can be sleeved inside the metal pipe and is connected in cooperation therewith. That is to say, the water inlet joint is screwed to the inner circumference of the metal pipe. The water inlet joint can communicate with the water inlet of the body.
[0027] To ensure sealing performance, a sealing ring 31 is provided between the end face of the water outlet end of the water inlet joint and the outer circumferential side wall of the water inlet of the body. Figure 1 Among them, the left side is the cold water inlet end and the right side is the hot water inlet end.
[0028] During installation, in order to position the fixing sleeve, an annular boss 22 is provided on the outer periphery of the side of the body. The annular boss can be in abutting cooperation with one end face of the metal sleeve. When the annular boss abuts against the metal sleeve, the fixing sleeve is installed in place. Referring to the drawings, the two fixing sleeves are located on the outer sides of both sides of the body. Two valve cores with different functions are provided on the outer sides of both sides of the body. The annular boss is located on the inner sides of both sides of the body.
[0029] Furthermore, a check valve 32 is provided inside the water inlet joint.
[0030] Preferably, the water inlet of the body includes a cold water inlet and a hot water inlet, which include two water inlet connectors and two fixing sleeves. The two fixing sleeves are sleeved on the outer peripheries of both sides of the body. A valve core seat 50 is arranged inside one side of the body. A temperature regulating valve core 51 is arranged inside the valve core seat. The temperature regulating valve core is fixed inside the body by a first nut 52. The first nut can be screwed with the inner periphery of the other end of a metal sleeve. The strength of the first nut for locking is concentrated on the fixing sleeve made of metal and will not be borne by plastic parts, ensuring the overall strength. The temperature regulating valve core can be communicated with the cold water inlet and the hot water inlet of the body through the valve core seat. The middle part of the body mainly has corresponding flow channels, which can communicate with the corresponding connectors and valve cores. It is similar to the prior art. Please refer to the attached drawings and no further detailed description of the flow channels will be given here.
[0031] Furthermore, a reversing valve 60 is further included. The reversing valve can be communicated with the water outlet end of the temperature regulating valve core. The reversing valve is arranged inside the other side of the body. The reversing valve is fixed inside the body by a second nut 61. The second nut can be screwed with the inner periphery of another metal sleeve. Similarly, the strength of the second nut for locking is concentrated on the fixing sleeve made of metal and will not be borne by plastic parts, ensuring the overall strength.
[0032] Referring to the attached drawings, an upper water outlet connector 71 and a lower water outlet connector 72 are further arranged on the body. The water outlet end of the reversing valve can be communicated with the upper water outlet connector or the lower water outlet connector, and is also communicated through the flow channels arranged on the body. The body is cylindrical. The housing is sleeved on the outer periphery of the body. The housing includes an arc-shaped front shell 11 and a rear cover 12. The radian of the front shell is greater than that of the rear cover.
[0033] More specifically, the present invention: The cold and hot water inlet connectors are fixedly connected to the body through the fixing sleeves, and the internal water channels and valve cores are fixedly connected through the fixing sleeves and nuts. In this way, local hardware parts are used in places where strength requirements are met (the connection of the cold and hot water inlet connectors, the burst pressure of the valve core connection, and the burst pressure of the water channels), ensuring the strength. In this way, other places can be made of plastic. That is to say, the outer shell and water channels can be made of plastic material, which greatly reduces the price of the whole set of products.
[0034] The above description shows and describes the preferred embodiments of the present invention. As mentioned above, it should be understood that the present invention is not limited to the form disclosed herein, should not be regarded as excluding other embodiments, but can be used in various other combinations, modifications and environments, and can be changed within the scope of the inventive concept described herein through the above teachings or the technology or knowledge in related fields. And the changes and modifications made by those skilled in the art without departing from the spirit and scope of the present invention should all be within the protection scope of the appended claims of the present invention.
