Detailed Implementation

[0029] To further illustrate the technical means and effects of this utility model in achieving its intended purpose, the following detailed description of the specific implementation methods, structure, features and effects of this utility model, in conjunction with the accompanying drawings and preferred embodiments, is provided below. Example 1

[0030] like Figures 1-2 As shown, a two-inlet, two-outlet valve core structure includes: valve core seat 1, valve core cover 2, valve core rod 6, upper ceramic plate 3, middle ceramic plate 4, and lower ceramic plate 5.

[0031] The upper ceramic sheet 3, the middle ceramic sheet 4, and the lower ceramic sheet 5 are stacked sequentially from top to bottom and rotated to seal each other. The ceramic sheets have good self-sealing properties, and the two ceramic sheets that are bonded together have good self-sealing properties.

[0032] The valve core seat 1 has a chamber 11 with two water inlet holes at the bottom. The upper ceramic plate 3, the middle ceramic plate 4 and the lower ceramic plate 5 are arranged in the chamber 11 from top to bottom. The bottom of the valve core seat 1 is snapped to a bottom cover 12, which has two connection holes corresponding to the water inlet holes.

[0033] The valve core cover 2 covers the top of the chamber 11 and is fixedly connected to the valve core seat 1. The top of the valve core cover 2 has two water outlet holes. The valve core cover 2 is fastened to the valve core seat 1 by screws. In this embodiment, the valve core cover 2 has a water outlet pipe 21 connected to the water outlet holes. The valve core cover 2 has its own water outlet pipe 21, so the faucet no longer needs to set up a corresponding pipeline structure to connect with the valve core. That is, the valve core cover has its own pipeline and can be used directly. That is, the valve core can be directly placed and fixed in the faucet housing; this simplifies and reduces the number of parts.

[0034] The upper ceramic plate 3 has two drainage holes 31, and the water outlet hole and the drainage hole 31 are connected in a one-to-one correspondence; the upper ceramic plate 3 has a through hole in the middle.

[0035] The middle ceramic sheet 4 has a through hole 41, and the middle part of the middle ceramic sheet 4 has a square hole 42. The bottom of the valve core rod 6 is a square rod matched with the square hole 42. The bottom of the valve core rod 6 is in transmission connection with the middle ceramic sheet 4, and the valve core rod rotates synchronously with the middle ceramic sheet. The top of the valve core rod passes through the through hole of the upper ceramic sheet and then passes out of the valve core cover.

[0036] The lower ceramic sheet 5 has two water passing holes 51. The water inlet hole is connected with the water passing hole 51 one by one.

[0037] The valve core structure has the following working modes by rotating the middle ceramic sheet 4 through the valve core rod 6:

[0038] The water outlet mode: rotate the middle ceramic sheet to make any one of the water passing holes communicate with any one of the water outlet holes through the through hole. Rotate the middle ceramic sheet to make the through hole connect different water passing holes and water outlet holes, so as to realize the switching of the water supply mode. The device is two-in and two-out, and usually supplies cold water and hot water.

[0039] The water supply mode: rotate the middle ceramic sheet to make the through hole not communicate with the water passing hole and the water outlet hole, or make the through hole only communicate with one of the water passing hole and the water outlet hole. The through hole, the water passing hole and the water outlet hole cannot form a through channel, and the water flow cannot pass through, so the water path is closed.

[0040] In this embodiment, the inner side wall of the chamber 11 has a fixed rib. The circumferential side wall of the upper ceramic sheet 3 and the lower ceramic sheet 5 each has a clamping groove 32 matched with the fixed rib. The fixed rib is embedded in the clamping groove 32, which can not only limit the rotation of the upper ceramic sheet and the lower ceramic sheet, but also precisely position and install the upper ceramic sheet and the lower ceramic sheet, so as to ensure the through and closing of the water path.

[0041] In this embodiment, the inner side wall of the chamber 11 has a limiting block for limiting the rotation of the middle ceramic sheet. The circumferential side wall of the middle ceramic sheet 4 has a sliding groove 43 in sliding connection with the limiting block.

[0042] The valve core seat of the device itself plays the role of the valve core cup. The valve core seat is directly fixedly connected with the valve core cover, so that one valve core cup is saved, the parts are simplified, and the production cost is reduced. Embodiment two

[0043] A two-in and two-out valve core structure, as shown in Figure 3 The structure is basically the same as that of embodiment one, and the difference is that the upper ceramic sheet has four circular water outlet holes, the lower ceramic sheet has an arc-shaped water passing hole 52 and a circular water passing hole. The arc-shaped water passing hole can cover the area of three water outlet holes, so that when the through hole rotates within the range of the arc-shaped water passing hole, water can be supplied when the through hole and any one of the water outlet holes are connected. Of course, the valve core cover is also provided with four water outlet holes and water outlet pipes.

[0044] The device mainly supplies water for the valve core through peripheral assembly, such as providing hot water, cold water, iced water and bubble water for the device, wherein the hot water separately passes through a pipe, i.e. through the circular water passing hole; the cold water, iced water and bubble water pass through the same pipe, i.e. through the arc-shaped water passing hole, and the rotating ceramic piece connects the three water outlet holes of the upper ceramic piece to realize different water outlet (only one kind of water passes through the pipe at the same time, one kind of water among the cold water, iced water and bubble water).

[0045] The above is only a preferred embodiment of the present application, and does not limit the present application in any form. Although the present application has been disclosed as above with a preferred embodiment, it is not intended to limit the present application. Any person skilled in the art can make slight changes or modifications to the above disclosed technical content to obtain equivalent embodiments without departing from the technical solution of the present application. Any modification, equivalent change and modification of the above embodiments according to the technical essence of the present application still belong to the scope of the technical solution of the present application.
