DETAILED DESCRIPTION

[0040] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present invention, and should not be construed as limiting the present invention.

[0041] The utility model relates to a valve component, comprising a valve core 100 and a water stop disc 200.

[0042] like Figure 1 , Figure 2 , Figure 3 and Figure 5 As shown, the valve core 100 is provided with a first channel 110 and a second channel 120, and a flow passage 130 is provided between the first channel 110 and the second channel 120. The flow passage 130 connects the first channel 110 and the second channel 120. The first channel 110 and the second channel 120 can be straight channels, or curved extensions, etc. The water stop disc 200 is installed in the valve core 100, and can be directly installed in the flow passage 130. The water stop disc 200 can be set to be, but not limited to, a disc shape, a fan shape, etc. The water stop disc 200 can change its position relative to the flow passage 130, and the position of the water stop disc 200 relative to the flow passage 130 has a first position and a second position. The water stop disc 200 is used to limit the liquid flow between the first channel 110 and the second channel 120 through the flow passage 130. The water stop disc 200 is provided with a flow hole 210, and the number of the flow hole 210 can be one or more. The water flow rate of the flow hole 210 is less than the water flow rate of the first channel 110 and the second channel 120 directly connected through the flow channel 130. The movement of the water stop plate 200 can be set to rotation, translation, etc. For example, a first opening connected to the first channel 110 and a second opening connected to the second channel 120 are opened on the flow channel 130. The first opening and the second opening are staggered up and down on the flow channel 130, and the water stop plate 200 moves in the flow channel 130 by translation. Figure 8 As shown, when the water stop plate 200 is translated to the first position, the water stop plate 200 is misaligned with both the first opening and the second opening, and the water stop plate 200 does not limit the flow of the first opening and the second opening. Fig. 9As shown, when the water stop plate 200 is translated from the first position to the second position, the water stop plate 200 is aligned with the first opening to block the first opening, and the flow channel 130 is connected with the first channel 110 through the flow hole 210, so as to limit the flow between the first channel 110 and the second channel 120, and reduce the liquid flow (water flow) between the first channel 110 and the second channel 120. For example, the first opening and the second opening are on the same end face of the flow channel 130, and the water stop plate 200 switches between the first position and the second position by rotating. When rotating to the first position, the water stop plate 200 is misaligned with the first opening and the second opening, and the first channel 110 and the second channel 120 are smoothly connected for liquid flow. When the water stop plate 200 rotates to the second position, the water stop plate 200 covers the first opening, and the first channel 110 and the second channel 120 are connected through the flow channel 130 and the flow hole 210 to limit the liquid flow. By switching the water stop plate 200 between the first position and the second position, the water flow between the first channel 110 and the second channel 120 can be quickly controlled in coordination with the water holes, which is convenient to use.

[0043] In this embodiment, the valve is used in a water intake device. The water intake device is a faucet, a shower, etc. The shower is used as an example for explanation. Fig.13 As shown, the valve member can be installed in the handle of the shower. The first channel 110 can be used as the water outlet of the shower, and the second channel 120 can be used as the water inlet of the shower. During normal use, the water stop plate 200 is in the first position, and water enters through the second channel 120, passes through the flow channel 130 and the first channel 110, and is sprayed out from the shower head for use. When the user needs to wash his hair, apply shower gel, etc., the water stop plate 200 can be switched to the second position, at which time the water output of the shower is reduced. The user can use the low water volume to wash his hair while showering, avoiding catching a cold after washing his hair after completely shutting off the water. The valve member can be used on the faucet. When applying hand soap, the user switches the valve member to the second position to achieve low water output from the faucet. After applying hand soap, the bubbles can be initially washed off in the low water state, and then the valve member is switched to the first position to drain the water with a large amount of water for the final cleaning.

[0044] In some embodiments of the utility model, a pressing assembly is also installed on the valve core 100. The water stop disc 200 is installed in the flow passage 130 by rotation to switch the position. The pressing assembly can be a shaft, a knob, etc. The pressing assembly is linked with the water stop disc 200, and the water stop disc 200 is controlled by the pressing assembly to rotate and switch between the first position and the second position.

[0045] In some specific embodiments of the present invention, Figure 1 and Figure 7As shown, the pressing assembly includes a push rod 300. The push rod 300 is disposed in the flow passage 130. The push rod 300 can be configured such that the axial direction of the push rod 300 is consistent with the axial direction of the water stop plate 200. The push rod 300 can be axially translated in the flow passage 130, and the translation positions are the third position and the fourth position. Fig.10 , Fig.11 and Fig.12 . In the direction shown in the figure, the push rod 300 can move upward to the third position and downward to the fourth position. The push rod 300 and the water stop plate 200 can be connected by an inclined platform. Whenever the push rod 300 moves from the fourth position to the third position, the push rod 300 can drive the water stop plate 200 to rotate through the inclined platform. If the water stop plate 200 is currently in the first position, it will rotate to the second position under the push of the inclined platform; if the water stop plate 200 is currently in the second position, it will rotate to the first position under the push of the inclined platform. The push rod 300 can also convert linear movement into rotation of the water stop plate 200 through other structures.

[0046] Further, such as Figure 5 and Figure 6 As shown, a countersunk hole 140 is provided on the flow channel 130. The countersunk hole 140 is formed by sinking downward at one end surface of the flow channel 130. In the direction shown in the figure, the axial direction of the countersunk hole 140 is up and down. A plurality of first guide pillars 150 are provided in the countersunk hole 140. The first guide pillars 150 can be formed on the side wall of the countersunk hole 140 and extend axially, and each first guide pillar 150 is distributed around the central axis of the countersunk hole 140 at intervals. A guide groove 151 is defined at the interval between two adjacent first guide pillars 150. The guide groove 151 extends along the axial direction of the countersunk hole 140. In this embodiment, as shown in FIG. Figure 4 As shown, four first guide pillars 150 are provided in the counterbore 140, and two, three or more first guide pillars 150 may also be provided. Four guide grooves 151 are correspondingly formed in the counterbore 140. A first inclined guide surface 152 is provided at the upper end of the first guide pillar 150, and the first inclined guide surface 152 is inclined around the central axis of the counterbore 140. The inclination direction of the first inclined guide surfaces 152 on each first guide pillar 150 is consistent. In the figure, the first inclined guide surfaces 152 on each first guide pillar 150 are all inclined downward in a counterclockwise direction around the central axis of the counterbore 140. As shown in FIG. Figure 7As shown, the push rod 300 is coaxially penetrated with the counterbore 140, and each first guide column 150 surrounds the push rod 300. A plurality of second guide columns 310 are provided on the push rod 300. The second guide columns 310 extend along the axial direction of the push rod 300, and each second guide column 310 is spaced and distributed around the central axis of the push rod 300. Each second guide column 310 is paired and slidably connected in each guide groove 151. The second guide column 310 and the guide groove 151 cooperate to guide the up and down movement of the push rod 300 relative to the counterbore 140. The upper end of the second guide column 310 is provided with a second inclined guide surface 311, and the second inclined guide surface 311 is inclined in the same direction as the first inclined guide surface 152, that is, the second inclined guide surface 311 is inclined counterclockwise downward around the axial direction of the push rod 300. The water stop plate 200 is provided with a guide portion 220, and the guide portion 220 can be extended downward from the lower side of the water stop plate 200. The guide portion 220 can be inserted into the counterbore 140, and the shape of the guide portion 220 is adapted to the shape of the space surrounded by each first guide column 150. A third guide column 230 is provided on the guide portion 220, and the third guide column 230 extends along the axial direction of the guide portion 220. The number of the third guide column 230 can be one, or the same as the number of the guide grooves 151. The lower end of the third guide column 230 faces the second guide column 310, and the shape of the lower end of the third guide column 230 is not limited, and can be set to a circular arc surface, a plane, or an inclined third inclined guide surface 231. The third inclined guide surface 231 can fit on the first inclined guide surface 152 or the second inclined guide surface 311 to slide relatively. Fig.10 As shown, initially, the second guide post 310 is located in the guide groove 151 and descends to the fourth position, and the third guide post 230 is also located in the guide groove 151, and the lower end of the third guide post 230 abuts against the second inclined guide surface 311. At this time, the water stop plate 200 is in the first position. Then the push rod 300 is pushed upward, and the second guide post 310 pushes the third guide post 230 upward to rise to the third position. Fig.11 As shown in FIG. 1 , when the second guide post 310 rises to the third position, the lower end of the third guide post 230 will be higher than the highest point of the first inclined guide surface 152, and the third guide post 230 will slide out of the current guide groove 151. The push rod 300 is reset to the fourth position, at which time the lower end of the third guide post 230 slides downward along the second inclined guide surface 311 and slides onto the first inclined guide surface 152. Fig.12As shown, the lower end of the third guide post 230 continues to slide along the inclined direction of the first inclined guide surface 152 until it falls into the next guide groove 151. During the process, the water stop plate 200 rotates counterclockwise relative to the countersunk hole 140 from the first position to the second position. If the push rod 300 is pushed from the fourth position to the third position, the third guide post 230 will repeat the above action, and the water stop plate 200 will rotate counterclockwise relative to the countersunk hole 140, switching from the second position to the first position, and the cycle will be repeated. In this embodiment, the four first guide posts 150 are evenly spaced in the countersunk hole 140, and the water stop plate 200 will rotate 90° every time the third guide post 230 switches from one guide groove 151 to the next adjacent guide groove 151.

[0047] Further, such as Figure 3 and Figure 4 As shown, a platform surface 131 is provided on the flow channel 130. The platform surface 131 can serve as an end surface of the flow channel 130. The countersunk hole 140 is provided on the platform surface 131, and the preferred countersunk hole 140 is located at the center of the platform surface 131. A first opening 132 is provided on the platform surface 131. In this embodiment, the water stop plate 200 rotates 90° each time, and two first openings 132 are correspondingly provided on the platform surface 131, and the two first openings 132 are distributed around the countersunk hole 140 and distributed at 180°. The first opening 132 connects the flow channel 130 with the first channel 110. The water stop plate 200 also includes a valve flap 240. As shown Figure 5 As shown, the number of valve flaps 240 is consistent with the number of first openings 132. Two valve flaps 240 are provided and are distributed at 180° on the water stop plate 200. Each valve flap 240 is provided with a flow hole 210. When the water stop plate 200 rotates, the valve flap 240 rotates accordingly. The position where the valve flap 240 covers the first opening 132 is the first position, and the position where the valve flap 240 is misaligned with the first opening 132 is the second position.

[0048] Further, such as Figure 1 and Figure 3As shown, the pressing assembly also includes a first elastic member 410 and a second elastic member 420. The first elastic member 410 and the second elastic member 420 can be components that can undergo elastic deformation, such as springs. In this embodiment, the first elastic member 410 and the second elastic member 420 are springs. The first elastic member 410 has a first elastic force on the push rod 300. The second elastic member 420 has a second elastic force on the water stop plate 200. The first elastic force can push the push rod 300 to move toward the fourth position. The external force pushes the push rod 300 to move from the fourth position to the third position. After the external force is lost, the first elastic force is used to automatically reset the push rod 300 and keep it in the fourth position. The second elastic force can push the water stop plate 200 to move toward the fourth position. When the third guide post 230 is pushed upward out of the guide groove 151 by the second guide post 310 , under the second elastic force, the lower end of the third guide post 230 slides obliquely downward along the second inclined guide surface 311 and the first inclined guide surface 152 , and then re-enters the next adjacent guide groove 151 .

[0049] In some specific embodiments of the present invention, Figure 1 and Figure 2 As shown, the valve core 100 is in the shape of a long rod. The first channel 110 and the second channel 120 are opened along the length direction of the valve core 100. A second opening 133 communicating with the second channel 120 is opened on the side wall of the flow channel 130. The flow channel 130 is opened along the radial direction of the valve core 100. One end of the flow channel 130 away from the counterbore 140 is opened on the side wall of the valve core 100 to form a third opening 134. A water sealing member 500 is installed at the third opening 134. One end of the push rod 300 away from the third opening 134 passes through the counterbore 140 and extends out of the valve core 100. One end of the first elastic member 410 can abut on the push rod 300, and the other end abuts on the water sealing member 500 as a fulcrum. One end of the second elastic member 420 can abut on the water stop plate 200, and the other end abuts on the water sealing member 500 as a fulcrum. The water sealing member 500 seals the third opening 134 and can be fixed to the third opening 134 by means of clamping, screw locking, etc. External force acts on the end of the push rod 300 extending out of the counterbore 140 to push the push rod 300. A sealing ring and other components can be installed at the position where the push rod 300 passes through the counterbore 140 for water sealing. With the arrangement of the above structure, the linkage structure of the pressing assembly and the water stop disk 200 fully utilizes the radial space of the valve core 100 and reduces the space occupied.

[0050] In some specific embodiments of the present invention, Figure 7As shown, a protrusion 320 is provided on the push rod 300. The protrusion 320 is arranged along the circumference of the push rod 300, that is, the protrusion 320 is arranged around the outer wall of the push rod 300. The end surface (upper end surface) of the protrusion 320 facing the water stop plate 200 is provided with a wedge-shaped protrusion 321, and the wedge-shaped protrusion 321 protrudes upward in a triangular shape. The number of wedge-shaped protrusions 321 is consistent with the number of second guide pillars 310. The second guide pillar 310 is arranged on the circumferential outer wall of the protrusion 320, and the second guide pillar 310 is aligned with the wedge-shaped protrusion 321. One side surface of the wedge-shaped protrusion 321 is flush with the second inclined guide surface 311 to form a connecting surface. The end of the third guide pillar 230 can abut on the connecting surface between the wedge-shaped protrusion 321 and the second inclined guide surface 311. In this way, the contact surface between the end of the third guide pillar 230 and the push rod 300 is increased. A V-shaped depression is formed between adjacent wedge-shaped protrusions 321 , and the V-shaped depression can be used to support the lower end of the third guide column 230 , thereby ensuring that the push rod 300 can drive the third guide column 230 to move upward when moving to the third position.
