[0028] It should also be understood that the terms used in this specification of the embodiments of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the embodiments of the present invention. As used in the specification of the embodiments of the present invention and the appended claims, the singular forms "a", "an" and "the" are intended to include plural forms unless the context clearly indicates otherwise.

[0029] See also Figure 1-4The embodiment of the utility model provides an integrated water mixing valve core with a multiple sealing structure, including a base 1, an upper shell 2, an upper valve disc 3, a lower valve disc 4 and a rotating assembly 5. One end of the upper shell 2 is connected to the base 1, and the upper valve disc 3 is arranged between the rotating assembly 5 and the lower valve disc 4. The lower valve disc 4 is located at one end of the water inlet pipe 7. One end of the upper valve disc 3 is in contact with the lower valve disc 4, and the other end is mechanically connected to the rotating assembly 5. The rotating assembly 5 is partially located in the upper shell 2 and partially extends from the upper shell 2. The upper valve disc 3 and the lower valve disc 4 are located in the whole composed of the upper shell 2 and the base 1. When the end of the rotating assembly 5 extending from the upper shell 2 is rotated by an external force, it drives the upper valve disc 3 to rotate to realize single-pipeline water outlet and mixed water outlet of water from different pipelines. Please continue to refer to Figure 1 A gear structure 6 is provided at one end of the rotating assembly 5 away from the lower valve disc 4 to facilitate connection and driving by an external rotating mechanism.

[0030] See also Figure 3-4 Multiple water inlet ports 7 are provided at one end of the base 1. These ports 7 extend through the base 1 and are located at the end away from the lower valve disc 4. The lower valve disc 4 is provided with openings 8 corresponding to the number of water inlet ports 7, and these openings 8 are connected one-to-one with the water inlet ports 7. An external rotation mechanism drives the upper valve disc 3 to rotate, exposing the openings 8 on the lower valve disc 4 to achieve single-pipeline water outlet or multi-pipeline mixed water outlet. At least one water outlet 9 is provided on the sidewall of the upper housing 2 for draining water from the water inlet ports 7. Preferably, there are 2-5 water inlet ports 7, including but not limited to these. The specific number can be adjusted based on actual needs.

[0031] Please continue reading Figure 2 , the base 1 and the upper shell 2 of the utility model are snap-fit ​​connection, and there is no need for selective connection, which avoids the possibility of misalignment between the water inlet pipe port 7 and the lower valve disc 4 when the two are rotated and connected, which is conducive to the smooth flow of water and reduces the impact pressure of water on the utility model product caused by the smaller water flow cross-section due to misalignment; a clamping block 10 is provided on the base 1, and a matching clamping groove 11 is provided on the side of the lower valve disc 4. When the lower valve disc 4 is connected with the water inlet pipe port 7, that is, when the base 1 is connected to the upper shell 2, the clamping block 10 is correspondingly inserted into the clamping groove 11. The arrangement of the clamping block 10 and the clamping groove 11 enables the lower valve disc 4 to be relatively fixed in the base 1 and the upper shell 2, and will not be driven to rotate by the force generated by the rotation of the upper valve disc 3, thereby improving the stability of the structure and avoiding the possibility of misalignment between the water inlet pipe port 7 and the opening 8 during use.

[0032] Please continue reading Figure 3A first flat washer seat 12 is provided on the base 1 on the outer peripheral side of the water inlet pipe 7. The integrated water mixing valve core with a multiple sealing structure also includes a first flat washer 13, which is correspondingly disposed in the first flat washer seat 12. The configuration of the first flat washer seat 12 provides a relatively fixed space for the first flat washer 13, which helps prevent it from being misaligned during installation and affecting the sealing effect. The configuration of the first flat washer 13 helps improve the sealing effect between the external pipe fitting and the water inlet pipe 7 and prolongs the service life of the product. A first sealing ring seat 14 is provided on the outer wall of the water inlet pipe 7. The integrated water mixing valve core with a multiple sealing structure also includes a first sealing ring 15, which is correspondingly sleeved on the first sealing ring seat 14. The configuration of the first sealing ring seat 14 provides a relatively fixed space for the first sealing ring 15, which helps prevent it from sliding during installation and affecting the sealing effect. The configuration of the first sealing ring 15 further improves the sealing effect between the external pipe fitting and the water inlet pipe 7 and prolongs the service life of the product. In the present invention, there are two first sealing ring seats 14, which are spaced apart to achieve a good sealing effect without causing great difficulty in installation and removal. Including but not limited to this, one, three or more can also be set, which can be set according to actual sealing requirements; please continue to refer to Figure 4 At the other end of the base 1, a second flat washer seat 16 is provided on the outer periphery of the water inlet pipe 7. The integrated waterway mixing valve core with a multiple sealing structure also includes a second flat washer 17, which is correspondingly mounted in the second flat washer seat 16. The arrangement of the second flat washer seat 16 provides a relatively fixed space for the second flat washer 17, which helps prevent it from being misaligned during installation and affecting the sealing effect. The arrangement of the second flat washer 17 helps to improve the sealing effect between the lower valve disc 4 and the water inlet pipe 7 and prolong the service life of the product.

[0033] Please continue reading Figure 3 On the base 1 outside the first flat washer seat 12, there are 1-3 positioning posts 18 for installation and positioning. The positioning posts 18 are provided to facilitate the relative fixation of the product of the utility model with the external structure by placing the positioning posts 18 in the external positioning holes when installing the product, which helps to reduce the possibility of arbitrary rotation.
