Specific implementation

[0026] The technical scheme in the embodiments of the utility model will be described clearly and completely in combination with the drawings in the embodiments of the utility model. Obviously, the described embodiments are the preferred embodiments of the utility model, and should not be regarded as excluding other embodiments. Based on the embodiments of the utility model, all other embodiments obtained by the ordinary skilled in the art without creative labor fall within the scope of protection of the utility model.

[0027] Reference Figure 1As shown in the figure, this utility model provides a multifunctional valve core, which includes a housing 100, a fixed valve plate 200, and a movable valve plate 300. The housing 100 has an installation cavity, in which the fixed valve plate 200 and the movable valve plate 300 are located. The fixed valve plate 200 is fixedly connected to the housing 100, and the movable valve plate 300 is rotatably connected to the housing 100, so that the movable valve plate 300 can rotate relative to the fixed valve plate 200. The movable valve plate 300 has a first water passage groove 310 and a second water passage groove 320. The first water passage groove 310 extends to the middle of the movable valve plate 300, and the second water passage groove 320 extends to the side wall of the movable valve plate 300. The fixed valve plate 200 has a first water passage hole group, which can be connected through the first water passage groove 310. The fixed valve plate 200 and the side wall of the housing 100 have a second water passage hole group, which can be connected through the second water passage groove 320.

[0028] Specifically, such as Figure 2 , Figure 3 As shown, the multifunctional valve core provided in this embodiment includes a housing 100. A mounting cavity is provided within the housing 100 to accommodate a fixed valve plate 200 and a movable valve plate 300. The fixed valve plate 200 and the movable valve plate 300 are stacked within the mounting cavity. The fixed valve plate 200 is fixedly connected to the housing 100, and the movable valve plate 300 is rotatably connected to the housing 100, allowing the movable valve plate 300 to rotate relative to the fixed valve plate 200. The housing 100 has openings at both its top and bottom that communicate with the mounting cavity. The top opening is smaller to allow a torsion bar used to drive the movable valve plate 300 to extend into the mounting cavity and connect with the movable valve plate 300. The bottom opening is larger to allow the movable valve plate 300 and the fixed valve plate 200 to be inserted into the mounting cavity through this opening. Figure 2 , Figure 3 As shown, the fixed valve plate 200 has several protrusions around its periphery, and the side wall of the housing 100 has several grooves corresponding to the protrusions. The fixed valve plate 200 and the housing 100 are fixedly connected by the engagement of the protrusions and grooves. Preferably, the valve core also includes a base 400, which is located at the bottom of the mounting cavity to prevent the fixed valve plate 200 and the moving valve plate 300 from disengaging from the mounting cavity.

[0029] like Figure 5 As shown, the movable valve plate 300 is provided with a first water passage groove 310 and a second water passage groove 320. The first water passage groove 310 and the second water passage groove 320 are distributed radially along the movable valve plate 300. The first water passage groove 310 extends to the middle of the movable valve plate 300, and the second water passage groove 320 extends to the side wall of the movable valve plate 300. There is a gap between the first water passage groove 310 and the second water passage groove 320. When the movable valve plate 300 rotates relative to the fixed valve plate 200, the first sweep path formed by the first water passage groove 310 and the second sweep path formed by the second water passage groove 320 do not coincide.

[0030] like Figure 6As shown, a first water passage hole group is provided on the fixed valve plate 200. In this embodiment, the first water passage hole group includes a first water inlet hole 210 and a first water outlet hole 220, wherein the first water outlet hole 220 is located in the middle of the fixed valve plate 200, that is, the first water outlet hole 220 always coincides with the first water passage groove 310. The first water inlet hole 210 is located within the range of the fixed valve plate 200 corresponding to the first sweeping path. Therefore, when the movable valve plate 300 rotates to a specific position, the first water inlet hole 210 can be made to coincide with the first water passage groove 310, thereby allowing the first water inlet hole 210 to communicate with the first water outlet hole 220 through the first water passage groove 310. In other embodiments, the positions of the first water inlet hole 210 and the first water outlet hole 220 can be interchanged.

[0031] like Figure 1 As shown, a second water passage group is provided on the side wall of the fixed valve plate 200 and the housing 100. In this embodiment, the second water passage group includes two second water inlets 230 and two second water outlets 240. The two second water inlets 230 are located within the range corresponding to the second sweeping path on the fixed valve plate 200, and the two second water outlets 240 are located within the range corresponding to the second sweeping path on the side wall of the housing 100. When the movable valve plate 300 rotates to a specific position, the second water inlets 230 in a certain group can overlap with the second water passage groove 320, thereby allowing the second water inlets 230 in that group to communicate with the second water outlets 240 through the second water passage groove 320. In other embodiments, the positions of the second water inlets 230 and the second water outlets 240 can be interchanged, and the number of second water inlets 230 and the second water outlets 230 can also be other.

[0032] The fixed valve plate 200 also includes a closed position. In the closed position, the fixed valve plate 200 does not have a water passage hole, such as... Figure 6 As shown, in this embodiment, the closed position, the first water inlet 210, and two second water inlets 230 are evenly arranged around the first water outlet 220. In this embodiment, the outlet end of the first water inlet 210 is crescent-shaped, the outlet end of the second water inlet 230 is crescent-shaped, and the inlet ends of the first water inlet 210 and the second water inlet 230 are circular with equal diameters. Figure 3 As shown, three circular areas of the same diameter are provided on the fixed valve plate 200. The path swept out between the first water inlet hole 210 and the second water inlet hole 230 serves as the boundary. The part of the circular area within the boundary line is penetrated to form the first water inlet hole 210, and the part of the circular area within the boundary line is penetrated to form the second water inlet hole 230.

[0033] The multifunctional valve core provided by the embodiment can connect a type of liquid supply source to each first water inlet hole 210 and second water inlet hole 230 in actual work, and the liquid supply source can be a water heater, a water purifier, a soda water maker, an oxygen-rich water maker, or a tap water pipeline, etc. The first water outlet hole 220 and each second water outlet hole 240 are connected to a water outlet channel for outputting liquid. As the movable valve disc 300 rotates, the positions of the first water passing groove 310 and the second water passing groove 320 on the movable valve disc 300 change, as shown in Figure 7 When the movable valve disc 300 moves to make the first water inlet hole 210 communicate with the first water passing groove 310, the liquid connected to the first water inlet hole 210 can be output through the first water outlet hole 220, as shown in Figure 8 、 Figure 9 When the movable valve disc 300 moves to make the second water inlet hole 230 communicate with the second water passing groove 320, the liquid connected to the second water inlet hole 230 can be output through the second water outlet hole 240, as shown in Figure 10 When the movable valve disc 300 moves to make the first water passing groove 310 and the second water passing groove 320 in a closed position, the first water passing hole group and the second water passing hole group do not have a water inlet hole and a water outlet hole in communication, and the valve core is in a state of no output.

[0034] In other embodiments, a plurality of first water inlet holes 210 can also be provided, and each first water passing hole can be connected to a type of liquid supply source. When the fixed valve disc 200 rotates to make the first water passing groove 310 coincide with a first water passing hole, the first water inlet hole 210 is communicated with the first water outlet hole 220 through the first water passing groove 310, so as to realize output of different types of liquid from the first water outlet hole 220.

[0035] Compared with the prior art, the multifunctional valve core provided by the embodiment can form two completely independent water passing channels by arranging the first water passing groove 310 and the second water passing groove 320, reduce the mixing of different liquids due to sharing of a water passing channel, and ensure the purity of different types of liquid. On the other hand, part of the water passing holes are arranged on the side wall of the shell 100, so as to form more water passing channels in limited space, thereby facilitating the arrangement of the water passing holes on the fixed valve disc 200.

[0036] In some preferred embodiments, as shown in Figure 1As shown, the connection structure between the valve stem 500 and the movable valve plate 300 is non-centrally symmetrical, so that the valve stem 500 can only connect to the movable valve plate 300 at a unique angle. A first positioning mark 510 is provided on the valve stem 500, located outside the housing 100; the first positioning mark 510 indicates the position of the second water passage groove 320 on the movable valve plate 300. A second positioning mark 110 is provided on the housing 100, indicating the position of the closed position on the fixed valve plate 200. Therefore, the user can determine the current angle of the movable valve plate 300 inside the housing 100 by observing the first positioning mark 510 and the second positioning mark 110.

[0037] In other preferred embodiments, such as Figure 2 As shown, the valve stem 500 is equipped with positioning balls 600, and the housing 100 is equipped with several positioning grooves. Each positioning groove corresponds one-to-one with the closed position on the fixed valve plate 200, the first water inlet hole 210, and the two second water inlets 230. This serves two purposes: firstly, it limits the movement of the valve plate 300 by increasing the resistance it needs to overcome to rotate through the elastic group. When the fixed valve plate 200 rotates to its correct position, it can be better held in that position by the elastic balls, preventing accidental displacement of the valve plate 300. Secondly, it provides an indicator to remind the user that the valve plate 300 has rotated a certain angle.

[0038] In other preferred embodiments, sealing rings can be installed in locations requiring sealing, such as inside the valve core mounting cavity, outside the first water passage hole group, and outside the second water passage hole group, to improve sealing performance.

[0039] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and not to limit them. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of the present invention.
