[0027] In order to further explain the technical scheme of the utility model, the utility model will be described in detail below through specific embodiments.

[0028] The improved split valve core seat water inlet and outlet structure disclosed in the embodiment, as shown in Figures 1-4 , comprises a valve core seat body 11 provided with a water outlet hole 111 and a cold and hot water inlet hole (not visible in the figure), and the bottom of the valve core seat body 11 is provided with a downwardly extending cold and hot water inlet pipe 113 corresponding to the cold and hot water inlet hole, and the difference between the embodiment and the existing valve core seat body structure comprises the structural arrangement described as follows, and the specific structural positional relationship will be described in detail below in combination with the drawings. As shown in Figure 2 and Figure 4As shown, the valve core seat body 11 is provided with two sealing rings spaced apart from each other, including the upper sealing ring 12 above and the lower sealing ring 13 below, which can be tightly contacted with the inner wall of the shell to achieve the sealing of the assembly gap and prevent leakage, and the outer side wall of the valve core seat body 11 between the two sealing rings forms a water overflow space 14 that can overflow when water is used. The water overflow space 14 is formed in the bare space of the outer side wall, and the space size can be significantly larger than the water overflow space of the prior art structure, and can be up to all the circumferential space between the inner wall of the faucet shell and the outer side wall of the valve core seat body 11 between the two sealing rings. Specifically, the maximum space can also be set according to the setting or reduced to adapt to the space used. The water outlet on the faucet shell is assembled for use between the two sealing rings, so according to the product structure setting needs and the requirements of water flow, etc., the corresponding or corresponding of the water outlet of different shell heights can be realized by the setting position and interval distance of the two sealing rings. As shown in the embodiment, the two sealing rings are set at the upper and lower ends of the valve core seat body 11. Since the water overflow space 14 is basically used to realize the communication of the water outlet, therefore, the water outlet hole 11 must be connected to the structure mode of the water overflow space 14.

[0029] The above two sealing rings and the setting structure on the valve core seat body 11, as shown in Figure 1 and Figure 2 The valve core seat body 11 includes an upper seat body 114 and a lower sealing disc 115, and the lower sealing ring 13 of the two sealing rings is arranged on the outer side wall of the lower sealing disc 115 and is embedded by positioning groove structure. The lower sealing disc 115 is connected below the upper seat body 114 through the water inlet pipe section 1131 (i.e. the upper end section of the water inlet pipe 113) or can be connected below the upper seat body 114 in combination with the support connecting part 116. The specific structure of the support connecting part 116 can be uniformly distributed as shown in the figure. Multiple connecting blocks have the effect of balancing support and strengthening the lower sealing disc 115. The upper seat body 114 and the lower sealing disc 115 form a water outlet interlayer space 117 that communicates with the water overflow space 14. The water outlet hole 111 is provided on the bottom surface of the upper seat body 114 and communicates with the water outlet interlayer space 17. The structure has high structural strength, can further increase the water outlet space, improve the water flow, and the structure is convenient for mold injection and demolding.

[0030] Also, as shown in Figure 4 The structure is different from the above description and Figure 2The structure shown does not have a clear distinction between the upper seat 114 and the lower sealing disc 115 in the valve core seat 11. The upper sealing ring 12 and the lower sealing ring 13 are respectively set on the outer side wall of the valve core seat 1 near both ends, or as shown in the figure, the upper sealing ring 12 is set on the upper edge of the valve core seat 11. It can achieve anti-displacement positioning nesting through a step or concave-convex positioning structure. During assembly, the upper sealing ring 12 can abut against the upper end face of the inner wall of the faucet housing for sealing. Figure 2 The upper sealing ring 12 on the upper seat 114 shown is also like Figure 4 The upper surface shown can also achieve a good leak-proof sealing effect; the specific setting can be selected according to the structure of the faucet housing and valve core seat. Figure 4 In the structural configuration shown, the water outlet 111 is opened on the inner bottom surface of the valve core seat 11, and the valve core seat 11 is provided with a water outlet channel 118 on the outer wall of the valve core seat 11 from the water outlet 111 to the corresponding water outlet flooding space 14. As shown in the figure, the water outlet channel 118 is formed in the bottom of the valve core seat 11. The overall structure of this configuration is simple.

[0031] In the above-described structural configuration, the size of the water outlet flooding space 14 can be adjusted not only by setting the vertical spacing between the two sealing rings, but also by adjusting the diameter of the outer wall of the valve core seat 11. Setting the maximum outer diameter of the water outlet flooding space 14 to be smaller than the maximum outer diameter of the sealing rings or smaller than the maximum outer diameter of the valve core seat where the sealing rings are located, effectively creating a concave effect on the side wall of the water outlet flooding space 14, thus increasing the space. To enhance the structural strength of the valve core seat 11, reinforcing ribs 110 can be provided on the outer wall of the valve core seat 11 corresponding to the water outlet flooding space 14.

[0032] In addition, common sealing rings are those with a circular, elliptical, or polygonal cross-section, for example... Figure 2 As shown, the upper sealing ring 12 is disposed on the outer wall of the valve core seat 11. To ensure a stable and reliable leak-proof seal between the upper sealing ring 12 and the inner wall of the faucet housing, this utility model discloses a structure, such as... Figure 2 and Figure 3As shown, the upper sealing ring 12 adopts a sealing ring with a U-shaped structure in the rotary cross section, the opening 121 of the U-shaped structure is directed to the lower sealing ring 13, and the two arms of the U-shaped structure form a sealing inner ring 122 and a sealing outer ring 123. When the water is used, the water passing through the opening 121 of the U-shaped structure can enter the U-shaped structure, and the water pressure of the water can act on the opposite side walls of the sealing inner ring 122 and the sealing outer ring 123, so as to push the sealing inner ring 122 and the sealing outer ring 123 to the valve core seat body 11 and the faucet shell respectively, so that the upper sealing ring 12 is in a pressurized expansion state, so that a more stable and reliable anti-leakage sealing effect can be achieved. It should be noted that the water pressure should act on the opposite side walls of the sealing inner ring 122 and the sealing outer ring 123 to achieve the pressurized expansion sealing effect. In order to avoid the situation that the above effect is not affected, the outer side wall of the valve core seat body 11 is further provided with a positioning concave ring 119 for positioning and embedding the upper sealing ring 12, the outer diameter of the end portion of the sealing inner ring 122 is smaller than the outer diameter of the lower portion of the positioning concave ring 119, and the inner diameter of the sealing outer ring 123 is greater than the outer diameter of the lower portion of the positioning concave ring 119, that is, as shown in the figure, the end portion of the sealing inner ring 122 does not exceed the positioning concave ring 119, and the end portion of the sealing outer ring 123 is outside the positioning concave ring 119. In this way, when the water is used, the water pressure can directly act on the side walls between the sealing inner ring 122 and the sealing outer ring 123, so as to ensure that the sealing inner ring 122 and the sealing outer ring 123 can be pressurized and expanded outwardly, and the desired effect can be achieved.

[0033] The lower sealing ring 13 described above is usually assembled from the bottom up, and can adopt a sealing ring with a circular, elliptical or polygonal cross section, which can mainly select a structure that is not easy to deform and displace due to friction during assembly.

[0034] In summary, the improved split valve core seat water inlet and outlet structure has the advantages of being suitable for different faucet shell water outlet heights, greatly improving the water outlet space to increase the water outlet flow, simple and stable structure, stable and reliable anti-leakage sealing, and being beneficial to production and manufacturing.

[0035] The above embodiments and drawings do not limit the product shape and style of the utility model, and any appropriate changes or modifications made by ordinary skilled persons in the art shall be considered as not departing from the patent scope of the utility model.
