Description

Technical Field

[0001] The invention relates to a ceramic valve plate assembly, in particular to a water-dividing and water-draining valve plate assembly and a valve core with a switching function. Background Art

[0002] Most existing faucets have multiple water outlets. In order to control the direction of water outlet, a water diversion valve core is set behind the switch valve core to control the direction of water flow. For example, a shower faucet generally has a top spray outlet, a hand-held shower outlet and a bottom faucet outlet. When connected, the top spray and the hand-held shower are connected to the top spray outlet and the shower outlet through connecting pipes. When the switch valve core is closed, there will be accumulated water in the top spray connecting pipe and the shower connecting pipe. If the water stays in the pipe for a long time, it will deteriorate and breed bacteria, affecting the quality of water use. At the same time, it is easy to produce scale, rust and stink. In addition, if there is water accumulation in the pipe, the top spray and hand-held shower will continue to drip and make noise. When the accumulated water freezes and expands, it will cause the faucet to rupture, affecting the life of the faucet and the user experience and other hygiene problems.

[0003] The Chinese patent No. 2007200676772 discloses a faucet, including a valve core, on which a special drainage hole is arranged. When the valve core is closed, the water tank will cause the hole and the drainage hole to communicate so as to discharge the accumulated water in the faucet through the drainage hole. Although the valve core has a drainage function, a separate drainage hole needs to be arranged on the valve core, and a separate drainage port needs to be arranged on the faucet accordingly. The overall structure is complicated, and the valve core does not have a water distribution function, and the water distribution function cannot be achieved by directly increasing the number of water outlets on the valve core. Summary of the invention

[0004] In view of the deficiencies in the prior art, an object of the present invention is to provide a water-dividing and draining valve plate assembly, which does not require additional drainage holes and can realize the drainage function for multiple water outlet channels while having the switching and water-dividing functions.

[0005] The above technical objectives of the present invention are achieved through the following technical solutions: a water-dividing and draining valve plate assembly with a switching function, comprising a movable valve plate and a fixed valve plate that fit each other, and relative sliding can occur between the movable valve plate and the fixed valve plate, a water inlet channel is arranged on the fixed valve plate, and a plurality of water outlet channels are arranged around the outside of the water inlet channel, a long strip-shaped connecting groove is arranged on the movable valve plate, and an arc-shaped drain groove is arranged on the outside of one end of the connecting groove, when the valve core is opened, the two ends of the connecting groove are respectively connected to the water outlet channel and the water inlet channel, and the drain groove moves with the movable valve plate to avoid the water outlet channel connected to the water inlet channel; when the valve core is closed, the connecting groove moves toward the water inlet channel side and is disconnected from the water outlet channel, and the drain groove is connected to multiple water outlet channels at the same time.

[0006] Through the above technical solution, the multiple water outlet channels include two, three or more water outlet channels. The water outlet channels surround the outside of the water inlet channel. When the movable valve plate slides relative to the fixed valve plate, the two ends of the long connecting groove can respectively connect the multiple water outlet channels with the water inlet channel, thereby achieving the functions of switching and water distribution. During use, when the valve plate assembly is in a closed state, the drainage groove simultaneously connects the three water outlet channels, so that air is introduced into the pipeline, the sealing state is released, and water can be discharged from the lowest water outlet of the faucet under the action of gravity, so that water will not accumulate in the pipeline.

[0007] Preferably, the water inlet channel is arranged in the middle of the fixed valve plate, and the water outlet channel is arranged outside the water inlet channel on one side of the fixed valve plate.

[0008] Through the above technical solution, the water outlet channel is concentrated on one side of the fixed valve plate. When the water outlet channel needs to be switched, the movable valve plate can be switched by rotating a small angle, which is more convenient to use. In addition, the water outlet channel is concentrated on one side of the fixed valve plate. When the valve core is closed, the movable valve plate only needs to slide to the side away from the water outlet channel. There is no need to consider the problem of the water outlet channel on the other side of the movable valve plate being connected to the water inlet channel due to the change in the position of the connecting groove. The overall structure of the valve core is simpler.

[0009] Preferably, the curvature of the drainage groove on the movable valve plate is greater than the curvature of the water outlet channel on the fixed valve plate.

[0010] Through the above technical solution, when the movable valve plate rotates to close the connection state between the connecting groove and the outermost water outlet channel of the movable valve plate, the drainage groove can still connect all the water outlet channels, thereby realizing the drainage function. No matter which water outlet channel the connecting groove is connected to when sliding the valve core to the other side of the water outlet channel to close the valve core, the drainage groove can always connect multiple water outlet channels at the same time after the valve core is closed, thereby realizing the drainage function.

[0011] Preferably, the drainage groove is U-shaped as a whole.

[0012] Through the above technical solution, the drainage groove is arranged in this way, and the whole is also arc-shaped, but compared with the circular arc, the area occupied is smaller, and the volume of the movable valve plate can be reduced.

[0013] Preferably, the movable valve plate and the fixed valve plate are symmetrically arranged on left and right sides.

[0014] Through the above technical solution, the movable valve plate and the fixed valve plate are arranged in this way, so that when switching the water outlet channel, the movable valve plate rotates to the same angle on the left and right, and the operation is more convenient.

[0015] Preferably, the edges of the movable valve plate and the fixed valve plate are provided with grooves.

[0016] Through the above technical solution, the movable valve plate can be easily engaged with the pushing slider, so as to adjust the position of the movable valve plate, change the relative position of the movable valve plate and the fixed valve plate, and change the water outlet state.

[0017] Another object of the present invention is to provide a water-dividing and draining valve core with a switching function, comprising a shell and a base, wherein a handle, a rotating seat, and a pushing slider are installed in the shell, the rotating seat is rotatably arranged at the upper end of the shell, the handle is hinged in the rotating seat, the upper end of the handle extends from the upper end of the rotating seat, and the lower end of the handle is engaged with the pushing slider, and is characterized in that: it also includes the above-mentioned valve plate assembly, the fixed valve plate is fixed on the base, and the movable valve plate is fixed on the pushing slider.

[0018] According to the above technical solution, by pulling the handle up and down, the push block can drive the movable valve plate to slide relative to the fixed valve plate, thereby controlling the on and off of the water flow. By turning the handle, the quick-drive movable valve plate and the fixed valve plate can be controlled to rotate relative to each other, thereby controlling the water outlet direction.

[0019] Preferably, a protrusion is provided on the lower end surface of the base, a plurality of water outlet holes are provided in the protrusion, and the water outlet holes are communicated with the water outlet channel on the fixed valve plate.

[0020] Preferably, a mounting hole is provided at the upper end of the rotating seat, a spring and a positioning block are installed in the mounting hole, and a positioning hole is provided in the inner cavity of the shell.

[0021] Through the above technical solution, the rotation position of the rotating seat can be limited, so that the position control during the rotation process is more accurate.

[0022] Compared with the prior art, the present invention has the following beneficial effects: by setting the drainage groove, when the valve plate assembly is in the closed state, the drainage groove can simultaneously connect multiple water outlet channels. When the valve plate or valve core is installed in the faucet, the accumulated water in the faucet and the connecting pipe can be discharged from the lowest water outlet, thereby preventing the accumulated water from being in the pipe and the faucet for a long time, breeding bacteria, affecting the water quality, and preventing the formation of scale, rust and odor. At the same time, there is no water accumulation in the pipe, and when the temperature is low, the accumulated water will not freeze and expand in volume, causing the faucet to break and be damaged.

DETAILED DESCRIPTION

[0038] The present invention is further described in detail below in conjunction with the accompanying drawings.

[0039] This specific embodiment is merely an explanation of the present invention and is not a limitation of the present invention. After reading this specification, those skilled in the art may make non-creative modifications to the present embodiment as needed. However, as long as they are within the scope of the claims of the present invention, they are protected by the patent law.

[0040] Embodiment 1: A water-dividing and draining valve assembly with a switch function

[0041] like Figures 1 to 5 As shown, a water-dividing valve plate assembly with water-dividing and water-draining functions includes a movable valve plate 1 and a fixed valve plate 2. The upper surface of the fixed valve plate 2 fits the lower surface of the movable valve plate 1, and the two can move relative to each other. The edges of the movable valve plate 1 and the fixed valve plate 2 are both provided with a card slot 7, which is convenient for carding and fixing with other components. The fixed valve plate 2 is provided with a water inlet channel 3 and three water outlet channels 4 that penetrate the fixed valve plate 2. The water inlet channel 3 is located in the middle of the fixed valve plate 2, and the water outlet channel 4 is located in the upper half of the fixed valve plate 2. The water outlet channel 4 is fan-shaped and surrounds the outer side of the upper end of the water inlet channel 3. A long strip-shaped connecting groove 5 is provided on the movable valve plate 1, and an arc-shaped drainage groove 6 is provided on the outer side of the connecting groove 5. The drainage groove 6 is U-shaped as a whole, and the drainage groove 6 surrounds the outer side of one end of the connecting groove 5. The arc occupied by the drainage groove 6 on the movable valve plate 1 is greater than the arc occupied by the water outlet channel 4 on the fixed valve plate 2. When the movable valve disc 2 rotates to the side of the fixed valve disc 1 to close, the drainage groove 6 can still simultaneously connect the three water outlet channels 4. The movable valve disc 1 is symmetrically arranged on the left and right sides, and the connecting groove 5 and the drainage groove 6 are symmetrical about the symmetric plane of the movable valve disc 1. The fixed valve disc 2 is symmetrical on the left and right sides, and the water inlet channel 3 and the water outlet channel 4 on the fixed valve disc 2 are symmetrical about the symmetric plane of the fixed valve disc 2.

[0042] like Figure 6 As shown, the dotted line portion is used to indicate the position of the connecting groove 5 and the drainage groove 6 on the lower surface of the movable valve plate 1, and the solid line portion is used to indicate the position of the water inlet channel 3 and the water outlet channel 4 on the fixed valve plate 2. At this time, the valve plate assembly is in a closed state, and the movable valve plate 1 covers the fixed valve plate 2. As shown in the figure, at this time, the movable valve plate 1 is at the lower part of the fixed valve plate 2, and the connecting groove 5 is not connected to any water outlet channel 4. At this time, the drainage groove 6 is connected to the three water outlet channels 4 at the same time, so that the three water outlet channels 4 are connected to each other. When the valve plate assembly is installed on a faucet with multiple water outlet channels 4, air is introduced into the pipeline to release the sealing state, and water can be discharged from the lowest water outlet of the faucet under the action of gravity, so that water will not accumulate in the pipeline. When the movable valve plate 1 is from Figure 6 Slide up to the status Figure 7 In the position shown, the two ends of the connecting groove 5 are respectively connected to the water inlet channel 3 and the middle water outlet channel 4, so that the middle water outlet channel 4 can discharge water. By controlling the distance that the movable valve plate 1 slides upward, the water output of the water outlet channel 4 can be controlled. While the connecting groove 5 slides upward, the drainage groove 6 also moves toward the upper side of the movable valve plate 1, so that the middle water outlet channel 4 will not be connected with the drainage groove 6, and the water outlet channels 4 on both sides will not discharge water. At the same time, the connecting groove 5 can connect the water outlet channels 4 on both sides, so that these two water outlet channels 4 can be drained first, and the water in the pipeline is discharged from the lower water outlet connected to the two water outlet channels 4.

[0043] The movable valve plate 1 can also rotate relative to the fixed valve plate 2. Figure 7 When the state is turned to the left, it can be turned to Figure 8 At this time, the connecting groove 5 is connected with the water outlet channel 4 on the left side of the fixed valve plate 2, and water flows out of the water outlet channel 4 on the left side. Figure 8 When the state slides away from the left water outlet channel 4, the relative positions of the movable valve plate 1 and the fixed valve plate 2 are as follows: Fig. 9 As shown, at this time, the connecting groove 5 is not connected to any water outlet channel 4, and the valve plate assembly is in a closed state, but the drainage groove 6 is connected to three water outlet channels 4 at the same time, so that when the valve plate assembly is installed in the faucet, the accumulated water in the faucet and the pipeline can be discharged from the lowest water outlet. Figure 7 The water outlet state of the valve plate assembly when the state is rotated to the right is similar to that when the movable valve plate 1 is rotated to the left, and will not be repeated here.

The rotating seat 10 is rotatably installed on the upper end of the housing 8, and the rotating seat 10 can rotate relative to the housing 8. The middle part of the handle 9 is hinged to the middle part of the rotating seat 10 through a hinge shaft 13, and the handle 9 can swing in the rotating seat 10. The upper and lower ends of the handle 9 extend out of the rotating seat 10. The lower end of the handle 9 is engaged with the push slider 11, thereby driving the push slider 11 to slide or rotate. The push slider 11 is provided with a latch tooth 21, which is inserted into the latch groove 7 at the edge of the moving valve plate 1, so that the two are fixed. When the handle 9 drives the push slider 11 to move, the movable valve plate 1 also moves with the push slider 11, thereby changing the relative position of the movable valve plate 1 and the fixed valve plate 2, and realizing the control of the water outlet size and water outlet direction. The base 14 is also provided with a latching tooth 21 to fix the fixed valve plate 2. The base 14 is provided with a water inlet hole 16 and a water outlet hole 15 corresponding to the fixed valve plate 2, a sealing ring 22 is provided between the base 14 and the fixed valve plate 2, and a sealing ring 22 is also provided on the lower end surface of the base 14.
