Description

Technical Field

[0001] The invention belongs to the technical field of valve cores, in particular to a water diversion valve core with a drainage switch. Background Art

[0002] Thermostatic faucets are widely used in people's daily lives. Thermostatic faucets have the function of outputting cold water, hot water and mixed water. The valve core is an important component of the thermostatic faucet. The valve core is a valve part that the valve body uses its movement to achieve the basic functions of direction control, pressure control or flow control. Among them, the hot and cold water ceramic valve core is the most common valve core component on the market to control the water output status. Usually, the water output of the hot and cold water ceramic valve core is achieved by the user to toggle the joystick. The user toggles the joystick to one side to achieve water output, and toggling it in the opposite direction reduces the water output.

[0003] Thermostatic faucets are generally installed in bathroom products for use. During use, when the thermostatic faucet is closed, water accumulates in the entire faucet cavity and the shower product pipeline, so the following problems will occur: 1. The accumulated water in the faucet is used by other water outlets in the home. When the water in the pipeline flows, air is injected into the shower faucet with accumulated water. The accumulated water in the shower faucet cavity will drip onto the ground, making noises and causing water to accumulate on the originally clean ground, greatly reducing the user experience; 2. The longer the water accumulates in the faucet cavity and the shower product pipeline, the more likely it is that bacteria will breed in the accumulated water, metal parts will rust, the accumulated water will stink, and scale will be produced. When in use, the water with bacteria will be sprinkled on the user's skin, posing a great safety hazard to human health; 3. In northern regions, the accumulated water in the faucet cavity and the shower product pipeline is prone to freezing. After freezing, the accumulated water increases in volume, which in turn causes the faucet and pipeline to be cracked, causing damage to the faucet and shower product. For example, the China Patent Network discloses a synchronous switch valve core [Authorization Announcement No.: CN211082942U], including a shell, a base, a handle, a rotating seat, an upper body and a lower body. The lower end of the upper body is provided with a first water guide cavity, a second water guide cavity and a third water guide cavity for guiding water in sequence along the circumferential direction. The upper end of the lower body is abutted with the lower end of the upper body, and the lower end of the lower body is fixedly connected to the base. The lower body is provided with a first water inlet hole, a first water outlet hole, a second water outlet hole and a third water outlet hole in sequence along the circumferential direction, and the center of the lower body is provided with a second water inlet hole. When the upper body rotates to the first position, the valve core is closed, and the water inlet hole and the water outlet hole are not connected, so that the valve core closes the cold water inlet or the hot water inlet while closing the mixed water. Although the amount of water supplied by the valve core to the inside of the faucet is reduced, there is still water accumulation in the faucet cavity and the pipeline of the shower product.

[0004] In addition, the China Patent Network discloses a faucet that can automatically drain the water accumulated in the internal channel [Authorization Announcement No.: CN101387346B], including a faucet main body, a valve core assembly is arranged in the valve seat of the faucet main body, the valve core assembly includes a fixed valve plate, a movable valve plate and a switching rod, the switching rod is equipped with a control handle, a water tank is provided on the movable valve plate, a first water inlet hole and a first water outlet hole are provided on the fixed valve plate, a first drainage hole is also provided on the fixed valve plate, and a second drainage hole is provided on the valve seat that is communicated with the first drainage hole, and the second drainage hole is communicated with the outside world. When the control When the handle is turned to the position of closing the faucet water outlet, at least in one position state, the water groove on the movable valve plate can communicate with the first drainage hole and the first water outlet hole. A block is also arranged in the water groove of the movable valve plate, which divides the water groove into an inlet groove and an outlet groove. A water channel connecting the inlet groove and the outlet groove is formed above the water groove. The first water outlet hole of the fixed valve plate is arranged in a direction close to the water outlet pipe. The water outlet groove of the movable valve plate is also close to the edge of the fixed valve plate on the fixed valve plate away from the first water outlet hole, and is located between the edge of the fixed valve plate and the first water inlet hole. The first drainage hole is distributed in the shape of a long arc. When the user pulls the control handle, the fixed valve plate slides and rotates accordingly. When the user turns the control handle to the position of closing the water outlet, the block set in the water tank of the movable valve plate just blocks the two first water inlet holes, and the water inlet tank covers the first water outlet hole, and the water outlet tank covers the first drain hole. The water inlet tank and the water outlet tank communicate through the water channel, so that the accumulated water in the faucet outlet channel enters from the first water outlet hole, flows through the water inlet tank, the water channel, the water outlet tank, the first drain hole and the second drain hole to be discharged to the outside. The above-mentioned faucet has only one water inlet hole and one water outlet hole, and the existing shower kit generally includes a shower head, a shower showerhead and a shower faucet. The valve core assembly in the faucet disclosed in the above patent cannot be used in conjunction with the shower kit. Summary of the invention

[0005] The purpose of the present invention is to address the above-mentioned problems in the prior art and to propose a water diversion valve core with a drainage switch. The technical problem to be solved by the present invention is: how to solve the problem that the accumulated water in the shower kit cannot be drained when the faucet is turned off.

[0006] The purpose of the present invention can be achieved by the following technical solutions:

[0007] A water diversion valve core with a drainage switch comprises an outer shell, a base, a switching rod, a rotating seat, a fixed valve plate and a movable valve plate, wherein the base is arranged at the lower end of the outer shell, the fixed valve plate, the movable valve plate and the rotating seat are all located in the outer shell and are arranged in sequence from bottom to top, the fixed valve plate is positioned on the base, the movable valve plate is positioned on the rotating seat, one end of the switching rod is connected to the rotating seat, and the other end extends out of the outer shell, characterized in that at least two water outlet holes are provided on the fixed valve plate, and a water inlet is provided on the movable valve plate, each water outlet hole can be connected to the water inlet, and a connecting groove is provided on the lower surface of the movable valve plate, and the connecting groove can be connected to at least two water outlet holes at the same time.

[0008] The valve core is assembled on a bathroom kit with multiple water outlets for use. For example, a shower kit has a shower faucet, a shower head and a shower nozzle, wherein the shower faucet is connected to one of the water outlet holes, and the shower head and / or the shower nozzle are respectively connected to the remaining water outlet holes. The switching lever is rotated to drive the rotating seat to rotate in the shell. After the rotating seat rotates, the driving valve plate is driven to rotate relative to the fixed valve plate. When the water inlet is connected to the water outlet hole corresponding to the shower faucet, the shower faucet is normally supplied with water, that is, the shower faucet discharges water. When the water inlet is connected to the water outlet hole corresponding to the shower head or the shower nozzle, the shower head or the shower nozzle is normally supplied with water, that is, the shower head or the shower nozzle discharges water. When the water inlet is not connected with the water outlet hole corresponding to the shower faucet, the shower head or / and the shower nozzle, the connecting groove connects the water outlet hole corresponding to the shower faucet, the shower head or the shower nozzle, and the accumulated water in the pipes corresponding to the shower head or / and the shower nozzle flows back into the water outlet hole of the shower faucet through the connecting groove, so that the accumulated water in the pipes corresponding to the shower faucet, the shower head or / and the shower nozzle are all discharged outward through the shower faucet, avoiding the problem that the accumulated water in the pipes corresponding to the shower faucet, the shower head or / and the shower nozzle cannot be discharged, solving the problem of dripping when the bathroom products are not in use, improving the user experience, avoiding the problems of rusting of metal parts and scaling caused by water accumulation in the pipes of the bathroom kit, extending the service life of the bathroom kit, avoiding the freezing of the accumulated water in the faucet and the pipe and causing the faucet and the pipe to be cracked, further improving the service life of the bathroom kit.

[0009] In the above-mentioned water diversion valve core with a drainage switch, all water outlet holes are arranged along the circumference of the fixed valve plate, and the connecting groove is arc-shaped. When the valve core is closed, the connecting groove is connected to all water outlet holes for connecting external pipes. When the valve core is in use, the pipelines of the shower kit are connected to the corresponding water outlets in sequence. When the valve core is closed, the connecting groove is connected to all the water outlets of the shower kit pipelines. At this time, the accumulated water in all the pipelines flows back to the connecting groove and gathers in the connecting groove. Since the connecting groove is connected to all the water outlets of the shower kit pipelines, the accumulated water is discharged from the water outlets corresponding to the shower faucet. During use, closing the valve core is a necessary action after each use. The function of draining the accumulated water in the pipeline is realized when the valve core is closed, thereby ensuring that the accumulated water in the pipeline can be drained after each use, thereby improving the convenience of drainage operation. In addition, the structural design of the valve core can be used on all shower faucets with water diversion and closing functions, and the valve core mainly improves the structure of the moving valve plate, which will not cause product design restrictions and has no effect on the product's styling design.

[0010] In the above-mentioned water-dividing valve core with a drainage switch, there are four water outlet holes, which are evenly distributed along the circumference of the fixed valve plate. When the water inlet is connected to one of the water outlet holes, the connecting groove is connected to the other three water outlet holes. When this valve core is assembled on a shower kit, the shower faucet, shower head and shower nozzle are respectively connected to the corresponding water outlet holes, and the last water outlet hole is blocked. When the water inlet is connected to the water outlet hole corresponding to the shower faucet, the shower faucet discharges water, and the connecting groove connects the water outlet hole corresponding to the shower head, the water outlet hole corresponding to the shower nozzle and the fourth water outlet hole;

[0011] When the water inlet is connected to the water outlet hole corresponding to the shower head, water flows out of the shower head, and the connecting groove connects the water outlet hole corresponding to the shower faucet, the water outlet hole corresponding to the shower head, and the fourth water outlet hole. At this time, the accumulated water in the corresponding pipes of the shower faucet and the shower head is discharged outward through the water outlet hole of the shower faucet;

[0012] When the water inlet is connected to the water outlet hole corresponding to the shower head, water flows out of the shower head, and the connecting groove connects the water outlet hole corresponding to the shower faucet, the water outlet hole corresponding to the shower head, and the fourth water outlet hole. At this time, the accumulated water in the corresponding pipes of the shower faucet and the shower head is discharged outward through the water outlet hole of the shower faucet;

[0013] When the water inlet is connected to the fourth water outlet, the valve core is in a closed state, and the connecting groove connects the water outlet corresponding to the shower faucet, the water outlet corresponding to the shower head, and the water outlet corresponding to the shower head. At this time, the accumulated water in the corresponding pipelines of the shower faucet, shower head, and shower head is discharged outward through the water outlet of the shower faucet. The design of this structure makes it possible that no matter when the water inlet is connected to any water outlet, the connecting groove connects the water channels corresponding to the other three water outlets to each other, the shower faucet is located lower than the shower head and the shower head, and the accumulated water in the corresponding pipelines of the shower head and the shower head flows to the shower faucet. When the shower faucet is draining water outward, air enters the pipeline. Under the pressure of the air, the valve core is closed, that is, the water is automatically drained, and the accumulated water in each water channel is emptied.

[0014] In the above-mentioned water diversion valve core with a drainage switch, at least two water inlet holes are opened on the side wall of the shell, and the water inlet holes correspond to the water outlet holes one by one, and the water inlet can be connected with the water inlet hole and the corresponding water outlet hole. Through the arrangement of this structure, when the water inlet is connected with one of the water outlet holes, the water inlet is also connected with the water inlet hole corresponding to the water outlet hole, and water enters the valve core from the water inlet hole, and enters the external pipeline from the water inlet and the water outlet hole.

[0015] In the above-mentioned water diversion valve core with a drainage switch, at least two positioning grooves are opened in the circumferential direction on the inner circumferential surface of the shell, and a mounting hole is opened in the radial direction on the outer wall of the rotating seat. A top column which always has a tendency to move toward the shell side is arranged in the mounting hole. When the outer end of the top column extends into the positioning groove, the water inlet is connected with the water inlet hole and the corresponding water outlet hole. Through the arrangement of this structure, when the outer end of the top column extends into one of the positioning grooves, the rotating seat is positioned at this position, and at this time the water inlet is connected with the water inlet hole and the corresponding water outlet hole, and in the absence of external force, the connection between the water inlet, the water inlet hole and the water outlet hole is ensured to be stable.

[0016] In the above-mentioned water diversion valve core with a drainage switch, a snap-in hole is opened on the outer peripheral surface of the lower end of the shell, and the base has a cantilever snap-in, and a part of the base is embedded in the shell and the cantilever snap-in is snap-in in the corresponding snap-in hole. Through the arrangement of this structure, the base is snap-connected with the shell, and the installation of the base on the shell is stable and secure.

[0017] In the above-mentioned water diversion valve core with a drainage switch, a positioning notch is provided at the lower end of the shell, a flange is provided on the outer peripheral surface of the base, a convex block is provided on the upper surface of the flange, and the convex block is located in the positioning notch. Through the arrangement of this structure, the matching structure of the convex block and the positioning notch further limits the base in the circumferential direction, further improving the stability of the base installed on the shell.

[0018] In the above-mentioned water diversion valve core with a drainage switch, the outer edge of the base has a positioning block, and the outer peripheral surface of the fixed valve disc is provided with a second positioning groove, and the second positioning groove corresponds to the positioning block and the cantilever buckle one by one, and the positioning block and the cantilever buckle are both located in the corresponding second positioning groove. Through the arrangement of this structure, the positioning block and the cantilever buckle are both located in the corresponding second positioning groove, so that the fixed valve disc is circumferentially limited on the base, and the fixed valve disc cannot rotate circumferentially relative to the base. When the movable valve disc rotates, the fixed valve disc remains stationary.

[0019] In the above-mentioned water-dividing valve core with a drainage switch, at least two positioning grooves 3 are provided on the upper surface of the movable valve plate, and at least two positioning posts are provided on the lower surface of the rotating seat, and the positioning grooves 3 correspond to the positioning posts one by one, and the positioning posts are inserted into the positioning grooves 3. Through the arrangement of this structure, the matching structure of the positioning posts and the positioning grooves enables the rotating seat to drive the movable valve plate to rotate when the switching rod drives the rotating seat to rotate, so that the movable valve plate rotates relative to the fixed valve plate.

[0020] In the above-mentioned water diversion valve core with a drainage switch, a through hole is radially opened on the outer peripheral surface of the lower end of the switching rod, a positioning pin is inserted into the through hole, a positioning hole is opened on the upper surface of the rotating seat, a positioning groove 4 is opened on the hole wall of the positioning hole, the lower end of the switching rod is inserted into the positioning hole and one end of the positioning pin is located in the positioning groove 4, and the upper end of the positioning hole is connected to a limit cover for limiting the positioning pin from being separated from the positioning groove 4. Through the setting of this structure, the lower end of the switching rod is positioned on the rotating seat, and rotating the switching rod can drive the rotating seat to rotate, thereby driving the movable valve plate to rotate.
