Description

Technical Field

[0001] The utility model specifically relates to a water diversion valve core. Background Art

[0002] As people's living standards continue to improve, shower facilities are constantly innovating and upgrading. They are usually equipped with multiple water outlets such as shower faucets, shower faucets, and drain outlets. As the functions increase, the water diversion valve core in the shower setting also needs to be continuously innovated and upgraded to cooperate with the shower facilities. For example, the "Water Diversion Valve Core" disclosed in the patent "CN202020544578.4" is equipped with a valve housing assembly and a rotating assembly. The valve housing assembly is provided with a first water inlet and more than three first water outlets. The rotating assembly controls the water diversion valve core to be in a water outlet state or a closed state by rotation, which reduces the difficulty of operating the water diversion valve core and has a simple overall structure.

[0003] This type of water diversion valve core controls the rotation angle of the rotating component through the docking structure provided in the water diversion valve core, so that the user can quickly and easily switch the water diversion valve core to the water outlet state or the closed state. However, this structure is achieved by elastic deformation of the elastic pin. As the use time goes by and the use time increases, the elastic force of the elastic part will continue to decay, which will inevitably cause the gear control to be inaccurate, resulting in waste of water resources and affecting the user experience. Utility Model Content

[0004] The technical problem to be solved by the present invention is to provide a water diversion valve core in view of the deficiencies of the above-mentioned prior art.

[0005] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: a water diversion valve core, comprising a shell, a base and a control rod, wherein the outer peripheral surface of the shell is provided with a water inlet, the base is fixedly connected to the bottom of the shell, a diverter plate is provided between the shell and the base, at least two groups of water outlets are provided on the diverter plate, the lower end of the diverter plate is in contact with the base, the upper end of the diverter plate is provided with a diverter control assembly, the control rod is passed through the shell, the control rod is linked to the diverter control assembly, the diverter control assembly includes a diverter control plate and a sealing column, the diverter control plate is provided at Between the diverter plate and the shell, the sealing column is arranged corresponding to the water outlet, and a sealing column mounting port is provided on the diverter control plate, and the sealing column mounting port is arranged corresponding to the sealing column. The sealing column is installed in the sealing column mounting port, prompting the sealing column to be slidably connected with the diverter control plate, and a diverter control slide is provided between the diverter control plate and the diverter plate, and the lower end of the control rod is linked to the diverter control slide, and the control rod drives the diverter control slide to slide, prompting the diverter control slide to be linked with the sealing column, and the diverter control component controls the water diversion valve core to be in a blocked state or a water outlet state.

[0006] The above technical solution is adopted, by setting a diversion control plate and a sealing column sliding connection, a diversion control slide is provided at the lower end of the control rod, and the diversion control slide is linked to the sealing column. In the initial state, the diversion control slide and the sealing column are separated. At this time, the water diversion valve core is in a blocked state. When the user needs to control the water diversion valve core to be in a water outlet state, the user toggles the control rod to make the diversion control slide and the corresponding sealing column conflict and link, prompting the sealing column to slide upward along the central axis of the sealing column installation port. At this time, the water diversion valve core is in a water outlet state, and water can flow in from the water inlet and then flow out through the water outlet. Through this setting, the water diversion valve core can be accurately controlled to be in a blocked state or a water outlet state, thereby improving the sealing performance of the water diversion valve core, avoiding waste of water resources, and improving the user experience.

[0007] The above-mentioned water diversion valve core can be further configured as follows: an elastic member installation position is opened on the sealing column, an elastic member is provided in the elastic member installation hole, one end of the elastic member contacts the sealing column, and the other end passes through the diversion control plate.

[0008] With the above technical solution, water flows into the water diverter valve core through the water inlet. At this time, the water diverter valve core is in a blocked state. However, when the sealing column and the diverter plate are in contact and blocked, a gap is inevitably generated between them, causing part of the water to flow out of the gap, resulting in a waste of water resources. An elastic member mounting hole is provided on the sealing column, and an elastic member is provided in the elastic member mounting hole. One end of the elastic member is in contact with the sealing column, and the other end passes through the diverter control plate until it contacts the shell. By applying elastic pressure to the sealing column, the gap between the sealing column and the diverter plate is further reduced, thereby improving the sealing performance of the water diverter valve core. The user needs to switch the water diverter valve core to the water outlet state. When the closure is closed, the user can press the control lever to separate the sealing column from the diversion control slide. At this time, the user can press the control lever to make the diversion control slide and the sealing column come into contact with each other. At this time, the pushing force is greater than the sum of the elastic force of the elastic member and the gravity of the sealing column. At this time, the sealing column can slide upward along the central axis of the sealing column installation hole, and the water diversion valve core can be in the water outlet state. When the user switches the water diversion valve core from the water outlet state to the blocking state, the user presses the control lever to separate the sealing column from the diversion control slide. At this time, the elastic member can quickly reset the sealing column due to the elastic force, thereby improving the conversion efficiency of the water diversion valve core from the water outlet state to the blocking state, further avoiding the waste of water resources, and improving the user experience.

[0009] The above-mentioned water diversion valve core can be further configured as follows: a guide linkage is provided on the outer peripheral surface of the sealing column, a first inclined surface is provided at the lower end of the guide linkage, and a second inclined surface is provided at the upper end of the diversion control slide. The first inclined surface and the second inclined surface are arranged corresponding to each other, so as to promote the linkage between the sealing column and the diversion control slide.

[0010] By adopting the above technical solution, a guide linkage is provided on the outer peripheral surface of the sealing column, a first inclined surface is provided at the lower end of the guide linkage, and a second inclined surface is provided at the upper end of the diverter control slide. However, the user toggles the control lever to make the diverter control slide contact with the sealing column. At this time, the diverter control slide is guided by the first inclined surface and the second inclined surface, so that the sealing column can be slid upward more conveniently, and the water diversion valve core can be switched to the water outlet state more quickly, which reduces the difficulty of using the water diversion valve core, improves the practicality of the water diversion valve core, and improves the user experience.

[0011] The above-mentioned water diversion valve core can be further configured as follows: a sealing groove is provided at the lower end of the sealing column, a sealing member is sleeved on the sealing column, and the sealing member is arranged in the sealing groove.

[0012] When adopting the above technical solution, it is inevitable that a certain dimensional deviation will occur between the diversion control plate and the diversion plate during production, resulting in a certain gap between the sealing column and the diversion plate, causing insufficient sealing and waste of water resources. A sealing groove is provided on the sealing column, and a sealing member is provided on the sealing groove. The seal has elastic deformation force. When the sealing column and the diversion plate cooperate to produce a sealing effect, the seal can fill the gap between the sealing column and the diversion plate, further improving the sealing of the water diversion valve core, avoiding waste of water resources, and improving the user experience.

[0013] The above-mentioned water-dividing valve core can be further configured as follows: it includes a connecting component, the connecting component includes a clip and a limit plug-in, the clip is arranged on the upper end surface of the base, the outer peripheral surface of the shell is provided with a connecting clip, the clip is engaged in the connecting clip, so that the shell and the base are fixedly connected; the limit plug-in is arranged on the lower end surface of the shell, the outer peripheral surface of the base is provided with a limit socket, and the limit plug-in is plugged into the limit socket.

[0014] By adopting the above technical solution, when the user installs the shell on the base, a connecting bayonet is provided on the outer surface of the shell, and a buckle is provided on the upper end surface of the base. The user only needs to apply a little force to make the buckle produce elastic deformation until the connecting bayonet and the buckle are in a snap-fit ​​state, thereby reducing the difficulty of installing the water-dividing valve core; a limiting plug-in is extended from the lower end of the shell, and a limiting socket is provided on the outer surface of the base. When the user installs the shell on the base, the limiting plug-in cooperates with the limiting socket to guide, so that the buckle is accurately snapped into the connecting bayonet, further reducing the difficulty of installing the water-dividing valve core and improving production efficiency.

[0015] The above-mentioned water diversion valve core can be further configured as follows: a limiting groove is provided on the upper end of the diversion control plate, the limiting groove is arranged in a square shape, a limiting block is provided in the limiting groove, the limiting block is arranged corresponding to the limiting groove, and the control rod is passed through the limiting block, so that the control rod drives the limiting block to slide, and the limiting block slides along the limiting groove.

[0016] By adopting the above technical solution, a limit groove is provided at the upper end of the diversion control plate, a limit block is provided in the limit groove, and a control rod is passed through the limit block. When the user controls the water diversion valve core to be converted from a blocked state to a water outlet state, since the limit groove is square, the right-angle end corresponds to the sealing column and is linked. The diversion control slide and the limit block are driven to slide by the control rod. When the diversion control slide moves toward a sealing column, the control rod initially has a certain degree of freedom of movement. When the control rod drives the limit block to move close to the right-angle end of the limit groove, the limit groove and the limit block cooperate to guide, so that the diversion control slide is accurately in contact with the guide linkage until the diversion control slide and the sealing column offset each other, further reducing the difficulty of using the water diversion valve core for users, improving the practicality of the water diversion valve core, and improving the user experience.

[0017] The above-mentioned water diversion valve core can be further configured as: the control rod includes a first control rod and a second control rod, a first control ball is provided in the middle of the first control rod, the first control ball is in contact with the shell and linked, the lower end of the first control rod is provided with a plug hole, the second control rod is plugged into the plug hole, a control rod elastic member is provided between the first control rod and the second control rod, one end of the control rod elastic member is in contact with the first control rod, and the other end is in contact with the second control rod; a second control ball is provided at the lower end of the second control rod, which prompts the second control rod to be linked with the diversion control slide.

[0018] By adopting the above technical solution, the control rod is divided into a first control rod and a second control rod, the lower end of the first control rod is provided with a plug-in hole, the second control rod is plugged into the plug-in hole, and a control elastic member is provided between the first control rod and the second control rod. When the user controls the water diversion valve core and causes the control rod to drive the diversion control slide to slide toward the sealing column, the control elastic member will continuously provide elastic force to the second control rod, thereby promoting the efficiency of the second control rod in driving the diversion control slide to move toward the sealing column. When the user needs to move the control rod to the initial state, the second control rod continuously retracts into the plug-in hole along the inner circumferential surface of the plug-in hole, causing the control elastic member to be compressed, thereby converting to the initial state. Through this setting, the convenience of users using the water diversion valve core is further improved, the difficulty of using the water diversion valve core is reduced, and the user experience is improved.

[0030] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0031] like Figures 1 to 10The water diversion valve core shown in the figure includes a shell 1, a base 2 and a control rod 6. The outer peripheral surface of the shell 1 is provided with a water inlet 10. The base 2 is fixedly connected to the bottom of the shell 1. A diverter plate 3 is provided between the shell 1 and the base 2. Two groups of water outlets 30 are provided on the diverter plate 3. The lower end of the diverter plate 3 is in contact with the base 2. The upper end of the diverter plate 3 is provided with a diversion control component. The control rod 6 is passed through the shell 1. The control rod 6 is linked to the diversion control component. The diversion control component includes a diversion control plate 4 and a sealing column 5. The diversion control plate 4 is provided between the diverter plate 3 and the shell 1. The sealing column 5 is arranged corresponding to the water outlet 30, and a sealing column mounting port 40 is provided on the diversion control plate 4. The sealing column mounting port 40 is arranged corresponding to the sealing column 5. The sealing column 5 is installed in the sealing column mounting port 40, prompting the sealing column 5 to be slidably connected to the diversion control plate 4. A diversion control slide 7 is provided between the diversion control plate 4 and the diversion plate 3. The lower end of the control rod 6 is linked to the diversion control slide 7. The control rod 6 drives the diversion control slide 7 to slide, prompting the diversion control slide 7 to be linked with the sealing column 5. The diversion control component controls the water diversion valve core to be in a blocked state or a water outlet state.

[0032] By setting the diversion control plate 4 and the sealing column 5 to be slidingly connected, a diversion control slide 7 is provided at the lower end of the control rod 6, and the diversion control slide 7 is linked with the sealing column 5. In the initial state, the diversion control slide 7 and the sealing column 5 are separated. At this time, the water diversion valve core is in a blocked state. When the user needs to control the water diversion valve core to be in a water outlet state, the user toggles the control rod 6 to make the diversion control slide 7 and the corresponding sealing column 5 conflict and link, prompting the sealing column 5 to slide upward along the central axis of the sealing column mounting port 40. At this time, the water diversion valve core is in a water outlet state, and water can flow in from the water inlet 10 and then flow out through the water outlet 30. Through this setting, the water diversion valve core can be accurately controlled to be in a blocked state or a water outlet state, thereby improving the sealing performance of the water diversion valve core, avoiding waste of water resources, and improving the user experience.

[0033] An elastic member mounting hole 50 is formed on the sealing column 5 , and an elastic member 51 is disposed in the elastic member mounting hole 50 . One end of the elastic member 51 contacts the sealing column 5 , and the other end passes through the diversion control plate 4 .

[0034] Water flows into the water diversion valve core through the water inlet 10. At this time, the water diversion valve core is in a blocked state. However, when the sealing column 5 contacts and blocks the diversion plate 3, a gap is inevitably generated between them, causing part of the water to flow out of the gap, resulting in a waste of water resources. An elastic member mounting hole 50 is provided on the sealing column 5, and an elastic member 51 is provided in the elastic member mounting hole 50. One end of the elastic member 51 contacts the sealing column 5, and the other end passes through the diversion control plate 4 until it contacts the housing 1. By applying elastic pressure to the sealing column 5, the gap between the sealing column 5 and the diversion plate 3 is further reduced, thereby improving the sealing performance of the water diversion valve core. When the user needs to switch the water diversion valve core to the water outlet state, The user toggles the control lever 6 to make the diversion control slide 7 and the sealing column 5 come into conflict and interact. At this time, the driving force is greater than the sum of the elastic force of the elastic member 51 and the gravity of the sealing column 5. At this time, the sealing column 5 can slide upward along the central axis of the sealing column mounting hole 50, and the water diversion valve core can be in the water outlet state. When the user switches the water diversion valve core from the water outlet state to the blocking state, the user toggles the control lever 6 to separate the sealing column 5 from the diversion control slide 7. At this time, the elastic member 51 can quickly reset the sealing column 5 due to the elastic force, thereby improving the conversion efficiency of the water diversion valve core from the water outlet state to the blocking state, further avoiding the waste of water resources, and improving the user experience.

[0035] The outer surface of the sealing column 5 is provided with a guide linkage 53, the lower end of the guide linkage 53 is provided with a first inclined surface 54, and the upper end of the diversion control slide 7 is provided with a second inclined surface 70. The first inclined surface 54 and the second inclined surface 70 are arranged correspondingly to promote the linkage between the sealing column 5 and the diversion control slide 7.

[0036] A guide linkage 53 is provided on the outer peripheral surface of the sealing column 5, a first inclined surface 54 is provided at the lower end of the guide linkage 53, and a second inclined surface 70 is provided at the upper end of the diversion control slide 7. However, when the user toggles the control lever 6 to make the diversion control slide 7 contact with the sealing column 5, the diversion control slide 7 is guided by the first inclined surface 54 and the second inclined surface 70 to make it easier for the sealing column 5 to slide upward, so that the water diversion valve core can be switched to the water outlet state more quickly, thereby reducing the difficulty of using the water diversion valve core, improving the practicality of the water diversion valve core, and improving the user experience.

[0037] A sealing groove 52 is formed on the outer peripheral surface of the sealing column 5 , and a sealing member 53 is sleeved on the sealing column 5 , and the sealing member 53 is disposed in the sealing groove 52 .

[0038] During production, it is inevitable that the diversion control plate 4 and the diversion plate 3 will have certain dimensional deviations, resulting in a certain gap between the sealing column 5 and the diversion plate 3, resulting in insufficient sealing and waste of water resources. A sealing groove 52 is provided on the sealing column 5, and a sealing member 53 is sleeved on the sealing groove 52. The sealing member 53 has elastic deformation force. When the sealing column 5 and the diversion plate 3 cooperate to produce a sealing effect, the sealing member 53 can fill the gap between the sealing column 5 and the diversion plate 3, further improving the sealing of the water diversion valve core, avoiding waste of water resources, and improving the user experience.

The limiting plug-in 12 is plugged into the limiting socket 21.

[0040] When the user installs the shell 1 on the base 2, a connecting bayonet 11 is provided on the outer surface of the shell 1, and a buckle 20 is provided on the upper end surface of the base 2. The user only needs to apply a little force to make the buckle 20 elastically deform until the connecting bayonet 11 and the buckle 20 are in a snap-fit ​​state, reducing the difficulty of installing the water-dividing valve core; a limiting plug-in 12 is extended from the lower end of the shell 1, and a limiting socket 21 is provided on the outer surface of the base 2. When the user installs the shell 1 on the base 2, the limiting plug-in 12 and the limiting socket 21 cooperate and guide, prompting the buckle 20 to be accurately snapped into the connecting bayonet 11, further reducing the difficulty of installing the water-dividing valve core and improving production efficiency.

[0041] A limiting groove 43 is provided at the upper end of the diversion control plate 4. The limiting groove 43 is arranged in a square shape. A limiting block 44 is provided in the limiting groove 43. The limiting block is arranged corresponding to the limiting groove. The control rod 6 is passed through the limiting block 44, prompting the control rod 6 to drive the limiting block 44 to slide, prompting the limiting block 44 to slide along the limiting groove 43.

[0042] The upper end of the diversion control plate 4 is provided with a limit groove 43, and a limit block 44 is provided in the limit groove 43. The control rod 6 is passed through the limit block 44. When the user controls the water diversion valve core to be converted from the blocked state to the water outlet state, since the limit groove 43 is square, the right-angled end is linked to the sealing column 5, and the diversion control slide 7 and the limit block 44 are driven to slide by the control rod 6. When the diversion control slide 7 moves toward a sealing column 5, the control rod 6 initially has a certain degree of freedom of movement. When the control rod 6 drives the limit block 44 to move close to the right-angled end of the limit groove 43, the limit groove 43 and the limit block 44 cooperate to guide, so that the diversion control slide 7 is accurately in contact with the guide linkage 53 until the diversion control slide 7 and the sealing column 5 are offset, which further reduces the difficulty of using the water diversion valve core for users, improves the practicality of the water diversion valve core, and improves the user experience.

[0043] The control rod 6 includes a first control rod 60 and a second control rod 61. A first control ball 600 is provided in the middle of the first control rod 60. The first control ball 600 is in contact with the shell 1 and is linked. A plug hole 601 is provided at the lower end of the first control rod 60. The second control rod 61 is plugged into the plug hole 601. A control rod elastic member 62 is provided between the first control rod 60 and the second control rod 61. One end of the control rod elastic member 62 is in contact with the first control rod 60 and the other end is in contact with the second control rod 61. A second control ball 610 is provided at the lower end of the second control rod 61 to cause the second control rod 61 to be linked with the diversion control slide 7.

[0044] When the user controls the water diversion valve core, the control rod 6 drives the diversion control slide 7 to slide toward the sealing column 5, and the control elastic member 62 will continuously provide elastic force to the second control rod 61, so that the second control rod 61 drives the diversion control slide 7 to move toward the sealing column 5 efficiently. When the user needs to move the control rod 6 to the initial state, the second control rod 61 continuously retracts into the plug hole 601 along the inner circumferential surface of the plug hole 601, causing the control elastic member 62 to compress, thereby converting to the initial state. Through this arrangement, the convenience of the user in using the water diversion valve core is further improved, the difficulty of using the water diversion valve core is reduced, and the user experience is improved.

[0045] As shown in the figure, a second seal 13 is provided on the outer surface of the shell 1, a third seal 31 is provided on the diverter plate 3 corresponding to the water outlet 30, and a fourth seal 22 is provided on the base 2.

The third seal 31 is provided to fill the gap between the diverter plate 3 and the base 2, thereby improving the sealing performance of the water diversion valve core and improving the practical experience of the user.
