[0047] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this application belongs. The terminology used herein in the template description is for the purpose of describing particular embodiments only and is not intended to be limiting of this application. The term "and / or" as used herein includes any and all combinations of one or more of the associated listed items.

[0048] like Figures 1 to 7 As shown, some embodiments of this application provide a throttling valve core, which is mainly used in faucets, shower heads, tap water pipes, etc. Users can not only effectively control the actual water consumption through the throttling valve core, but also adjust the water consumption more accurately, thereby reducing water waste, optimizing the user's daily water needs, and improving the user experience.

[0049] The throttle valve core includes a moving plate 400, a stationary plate 800, and an elastic limiting structure.

[0050] The movable plate 400 and the stationary plate 800 are slidably connected along a first direction to adjust the throttle valve core between an open state and a closed state. It can be understood that the movable plate 400, while sliding relative to the stationary plate 800 along the first direction, can switch the throttle valve core from a closed state to an open state, and similarly, it can also switch the throttle valve core from an open state to a closed state.

[0051] In addition, the stationary plate 800 has a first water inlet 810, a second water inlet 820 and a mixing hole 830, and the moving plate 400 is provided with a water passage cavity 421. The water passage cavity 421 is connected to the mixing hole 830 and can be connected to the first water inlet 810 and / or the second water inlet 820.

[0052] It should be noted that when the throttle valve core is in the closed state, the water passage cavity 421 is connected to the mixing hole 830, and neither the first water inlet hole 810 nor the second water inlet hole 820 is connected to the water passage cavity 421. In some embodiments, when the throttle valve core is in the open state, the water passage cavity 421 is connected to the mixing hole 830, and either the first water inlet hole 810 or the second water inlet hole 820 is connected to the water passage cavity 421; in some embodiments, when the throttle valve core is in the open state, the water passage cavity 421 is connected to the mixing hole 830, and both the first water inlet hole 810 and the second water inlet hole 820 are connected to the water passage cavity 421.

[0053] In this embodiment, the first water inlet 810 is a hot water inlet, and the second water inlet 820 is a cold water inlet.

[0054] It is understandable that when the throttle valve core is in the closed state, the moving plate 400 moves relative to the stationary plate 800 in the first direction, thereby connecting the first water inlet hole 810, the second water inlet hole 820 and the mixing hole 830 to the water passage cavity 421, thus opening the throttle valve core. As the moving plate 400 moves, the diameter of the openings of the first water inlet hole 810, the second water inlet hole 820 and the mixing hole 830 connected to the water passage cavity 421 gradually increases, thereby gradually increasing the water flow rate.

[0055] The elastic limiting structure is disposed on the side of the moving piece 400 away from the stationary piece 800, and includes a first elastic limiting member 300 and a second elastic limiting member 500 that are movably connected.

[0056] In this embodiment, the first elastic limiting member and the second elastic limiting member 500 are configured such that when the moving piece 400 moves a preset distance relative to the stationary piece 800 along the first direction, the second elastic limiting member 500 and the first elastic limiting member 300 abut against each other to elastically limit the moving piece 400, and control the diameter of the first water inlet hole 810 and / or the second water inlet hole 820 respectively communicating with the water passage cavity 421, thereby adjusting the water flow through the first water inlet hole 810 and / or the second water inlet hole 820, thereby controlling the water output, avoiding the moving piece 400 sliding too far relative to the stationary piece 800, resulting in too much water output, thereby avoiding waste of water resources.

[0057] It is worth noting that since the first elastic limiting member 300 and the second elastic limiting member 500 are elastic, when the user needs to increase the water consumption during water use, the user can increase the force acting on the moving plate 400. When the force exerted by the user on the moving plate 400 is greater than the resistance generated by the mutual contact between the first elastic limiting member 300 and the second elastic limiting member 500, the second elastic limiting member 500 can move relative to the first elastic limiting member 300 under the action of external force, and the moving cover plate 410 can slide relative to the stationary plate 800 again, thereby increasing the diameter of the opening connecting the first water inlet hole 810 and / or the second water inlet hole 820 with the water passage cavity 421, thereby increasing the water output to meet the user's water consumption needs and improve the user's user experience.

[0058] like Figure 2 As shown, in some embodiments of this utility model, the movable piece 400 includes a movable cover piece and a movable piece body 420. The movable piece body 420 is disposed on the side of the movable cover piece facing the stationary piece 800, and is connected to the movable cover piece, meaning the movable cover piece can move synchronously relative to the movable piece body 420.

[0059] like Figure 2 As shown, in some embodiments of this utility model, the throttle valve core includes a convex sleeve 100 and a convex rod 200.

[0060] The protruding rod sleeve 100 defines the movable space 110 and partially houses the protruding rod 200 within the movable space 110. Simultaneously, the protruding rod 200 is rotatably connected to the protruding rod sleeve 100 to ensure smoothness and stability during the rotation of the protruding rod 200 relative to the protruding rod sleeve 100. It is understood that a portion of the protruding rod 200 is located outside the movable space 110.

[0061] The protruding rod 200 has an adjustment end 210 and a connecting end 220. The connecting end 220 is housed in the movable space 110 and rotatably connects the protruding rod 200 to the protruding rod sleeve 100. That is, the adjustment end 210 is located outside the movable space 110, so that the user can hold the adjustment end 210 to rotate and adjust the protruding rod 200, thereby adjusting the water output.

[0062] The first elastic limiting member 300 is disposed on the side of the protruding sleeve 100 away from the adjusting end 210, and the connection method between the first elastic limiting member 300 and the protruding sleeve 100 includes any one of magnetic connection, adhesive, snap-fit, threaded connection and bolt connection, which can be specifically set according to the actual situation.

[0063] It is understandable that by detachably connecting the first elastic limiting member 300 and the protruding rod sleeve 100, the first elastic limiting member 300 can be installed or replaced on the protruding rod sleeve 100, thereby allowing different models of the first elastic limiting member 300 to be replaced according to the user's actual usage, thus meeting the different water consumption needs of different users.

[0064] The movable cover plate 410 is slidably connected to the protruding rod sleeve 100, and the movable cover plate 410 is movably connected to the connecting end 220, so that during the rotation of the protruding rod 200 relative to the protruding rod sleeve 100, the movable cover plate 410 can be driven to slide synchronously relative to the protruding rod sleeve 100 through the connecting end 220, thereby realizing the adjustment of the output quantity.

[0065] The second elastic limiting member 500 is disposed on the side of the movable cover plate 410 facing the first elastic limiting member 300, and the second elastic limiting member 500 is adjacent to the first elastic limiting member 300. It should be noted that while the movable cover plate 410 slides relative to the protruding sleeve 100, the second elastic limiting member 500 slides synchronously relative to the first elastic limiting member 300.

[0066] It is understandable that the second elastic limiting member 500 and the movable cover plate 410 move synchronously.

[0067] In this embodiment, the second elastic limiting member 500 is configured such that when the protruding rod 200 rotates at a preset angle, the second elastic limiting member 500 and the first elastic limiting member 300 abut against each other. At this time, the elastic limiting structure formed by the second elastic limiting member 500 and the first elastic limiting member 300 can limit the movable cover plate 410 and the protruding rod 200, thereby controlling the rotation angle of the protruding rod 200 relative to the protruding rod sleeve 100 and controlling the sliding position of the movable cover plate 410 relative to the protruding rod sleeve 100. This achieves control over the water output, preventing the protruding rod 200 from rotating too much, which would cause the movable cover plate 410 to slide too far relative to the protruding rod sleeve 100, resulting in excessive water output and thus avoiding waste of water resources.

[0068] It is worth noting that since the first elastic limiting member 300 and the second elastic limiting member 500 are elastic, when the user needs to increase the water consumption during water use, the user can rotate the protruding rod 200. When the force exerted by the user on the protruding rod 200 is greater than the resistance generated by the mutual contact between the first elastic limiting member 300 and the second elastic limiting member 500, the second elastic limiting member 500 can move relative to the first elastic limiting member 300 under the action of external force. That is, at this time, the rotation angle of the protruding rod 200 relative to the protruding rod sleeve 100 increases, and the movable cover plate 410 can slide relative to the protruding rod sleeve 100 again. That is, the sliding distance of the movable cover plate 410 increases, thereby increasing the water output to meet the user's water consumption needs and improve the user's user experience.

[0069] It should be noted that the preset angle mentioned here refers to the preset rotation angle of the protruding rod 200 relative to the protruding rod sleeve 100. The preset angle ranges from 10° to 45°. This means that the preset angle can be any value among 10°, 11°, 12°, 13°, 14°, 15°, 16°, 17°, 18°, 19°, 20°, 21°, 22°, 23°, 24°, 25°, 26°, 27°, 28°, 29°, 30°, 31°, 32°, 33°, 34°, 35°, 36°, 37°, 38°, 39°, 40°, 41°, 42°, 43°, 44°, and 45°, and can be set according to actual conditions.

[0070] It is worth noting that in this embodiment, when the axis of the protruding rod 200 coincides with or is parallel to the axis of the protruding rod sleeve 100, the rotation angle of the protruding rod 200 relative to the protruding rod sleeve 100 is 0°. Simultaneously, the movable cover plate 410 is in its initial position and can block water flow. At this time, no water flows through the throttle valve core, meaning the regulating valve core is in the closed state. When the protruding rod 200 rotates relative to the protruding rod sleeve 100, the angle between the axis of the protruding rod 200 and the axis of the protruding rod sleeve 100 is greater than 0°. The movable cover plate 410 moves relative to the protruding rod sleeve 100, allowing water to flow through the throttle valve core. Furthermore, the water flow rate through the throttle valve core increases as the distance the movable cover plate 410 moves relative to the protruding rod sleeve 100 increases. It can be understood that the larger the angle between the axis of the protruding rod 200 and the axis of the protruding rod sleeve 100, the larger the water flow rate through the throttle valve core.

[0071] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the convex sleeve 100 includes a connecting cylinder 120 and a first connecting platform 130, wherein the first connecting platform 130 is disposed on one side of the connecting cylinder 120 in the axial direction.

[0072] The connection method between the connecting cylinder 120 and the first connecting platform 130 includes any one of threaded connection, bonding, hot melt connection or integral molding, which can be specifically set according to the actual situation.

[0073] In this embodiment, the connecting cylinder 120 and the first connecting platform 130 are integrally formed to improve the overall strength and stability of the convex sleeve 100.

[0074] In addition, the connecting cylinder 120 defines the movable space 110, which extends through the connecting cylinder 120 along its axial direction. The first connecting platform 130 is provided with a first guide groove 131 communicating with the movable space 110 on the side opposite to the connecting cylinder 120.

[0075] It should be noted that the first guide groove 131 is used to guide and limit the movement of the movable cover plate 410 during the movement process, so as to ensure the accuracy, stability and smoothness of the movement of the movable cover plate 410.

[0076] In this embodiment, the first connecting platform 130 is provided with a first mounting groove 132 on the side opposite to the connecting cylinder 120 for fixing the first elastic limiting member 300. The groove wall of the first mounting groove 132 provides a limiting and fixing function for the first elastic limiting member 300, so as to ensure the stability of the connection between the first elastic limiting member 300 and the first connecting platform 130.

[0077] like Figure 2 As shown, in some embodiments of this application, the first elastic limiting member 300 includes a first connecting block 310 and at least one first elastic member 320.

[0078] It is understandable that the number of the first elastic element 320 can be any number of one, two or more, and can be set according to the actual situation.

[0079] The first connecting block 310 is housed in the first mounting groove 132, meaning the first connecting block 310 is connected to the groove wall of the first mounting groove 132. The first connecting block 310 has at least one first slot 311 on the side facing the second elastic limiting member 500. It is understood that the number of first slots 311 can be one, two, or more, and can be specifically set according to the actual situation.

[0080] It should be noted that the number of first slots 311 is equal to or greater than the number of first elastic elements 320.

[0081] In this embodiment, the number of first slots 311 is equal to the number of first elastic members 320. One first elastic member 320 is correspondingly disposed in one first slot 311, and the first elastic member 320 at least partially protrudes from the first slot 311 so that the portion of the first elastic member 320 protruding from the first slot 311 can abut against the second elastic limiting member 500 to form a limiting structure, thereby achieving the limiting effect on the movement distance of the movable cover 410, and thus achieving the purpose of throttling.

[0082] like Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, there is one first slot 311 and one first elastic member 320, so that the first elastic member 320 provides a limiting effect on the second elastic limiting member 500. It can be understood that when the protruding rod 200 rotates by a preset angle, the first elastic member 320 abuts against the second elastic limiting member 500 to limit the protruding rod 200, ensuring the accuracy of the rotation angle of the protruding rod 200, thereby ensuring the accuracy of the moving position of the movable cover plate 410, and thus ensuring the accuracy of water output control, thereby avoiding water waste and achieving the purpose of water conservation.

[0083] In addition, in some embodiments of this application, there are multiple first slots 311 and multiple first elastic members 320, and the multiple first slots 311 are arranged at intervals along the sliding direction of the movable cover 410, and each first elastic member 320 is engaged in one first slot 311.

[0084] It should be noted that by setting multiple first slots 311 and multiple first elastic elements 320, the protruding rod 200 can achieve multi-level adjustment during rotation. That is, when the protruding rod 200 rotates to a preset angle, the second elastic limiting element 500 can abut against the first first elastic element 320. When the protruding rod 200 rotates to another preset angle, the second elastic limiting element 500 can abut against the second first elastic element 320, and so on, thereby achieving multi-level adjustment of water output. This allows users to more conveniently adjust the water consumption according to their own needs during water use, which not only achieves the purpose of saving water, but also improves the user experience and ease of use.

[0085] like Figure 2 , Figure 3 and Figure 5As shown, in some embodiments of this application, the movable cover plate 410 is provided with a first guide platform 411 on the side facing the first connecting platform 130. The first guide platform 411 is received in the first guide groove 131, and the side wall of the first guide platform 411 is slidably connected to the groove wall of the first guide groove 131, so as to provide guidance and limiting function for the first guide platform 411 through the first guide groove 131, so as to ensure the stability and smoothness of the first guide platform 411 during the sliding process in the first guide groove 131.

[0086] The first guide platform 411 has a relief groove 4111 on the side facing the protruding rod 200. The connecting end 220 is received in the relief groove 4111 and is movably connected to the groove wall of the relief groove 4111. This allows the connecting end 220 to rotate relative to the protruding rod sleeve 100 during the rotation of the protruding rod 200. During the rotation, the connecting end 220 can drive the cover plate 410 to move synchronously, thereby adjusting the water output.

[0087] like Figure 2 and Figure 5 As shown, in some embodiments of this application, the movable cover 410 has a second mounting groove 412 for fixing the second elastic limiting member 500 on the side facing the first connecting platform 130. The connection method between the second elastic limiting member 500 and the groove wall of the second mounting groove 412 includes any one of snap-fit, magnetic connection, or adhesive connection, which can be specifically set according to the actual situation.

[0088] It is understood that the second elastic limiting member 500 is detachably connected to the groove wall of the second mounting groove 412 to facilitate the installation or replacement of the second elastic limiting member 500.

[0089] like Figure 2 and Figure 3 As shown, in some embodiments of this application, the second elastic limiting member 500 includes a second connecting block 510 and at least one second elastic member 520.

[0090] It is understandable that the number of the second elastic element 520 can be one, two or more, and can be set according to the actual situation.

[0091] The second connecting block 510 is housed in the second mounting groove 412, meaning the second connecting block 510 is connected to the groove wall of the second mounting groove 412. The second connecting block 510 has at least one second slot 511 on the side facing the first elastic limiting member 300. It is understood that the number of second slots 511 can be one, two, or more, and can be specifically set according to the actual situation.

[0092] It should be noted that the number of second slots 511 is equal to or greater than the number of second elastic elements 520.

[0093] In this embodiment, the number of second slots 511 is equal to the number of second elastic members 520. One second elastic member 520 is correspondingly disposed in one second slot 511, and the second elastic member 520 at least partially protrudes from the second slot 511 so that the part of the second elastic member 520 protruding from the second slot 511 can abut against the first elastic limiting member 300 to form a limiting structure, thereby achieving the limiting effect on the moving distance of the movable cover 410, and thus achieving the purpose of throttling.

[0094] In this embodiment, the second elastic element 520 is configured such that when the protruding rod 200 rotates at a preset angle, the second elastic element 520 and the first elastic element 320 abut against each other to limit the moving cover plate 410 and the protruding rod 200, thereby controlling the water output.

[0095] In this embodiment, there is one second slot 511 and one second elastic member 520, so that the first elastic member 320 provides a limiting effect on the second elastic member 520. It is understood that when the protruding rod 200 rotates by a preset angle, the first elastic member 320 abuts against the second elastic member 520 to limit the protruding rod 200, ensuring the accuracy of the rotation angle of the protruding rod 200, thereby ensuring the accuracy of the moving position of the movable cover plate 410, and thus ensuring the accuracy of water flow control. This avoids water waste and achieves the purpose of water conservation.

[0096] like Figure 4 and Figure 5 As shown, in some embodiments, the first connecting block 310 has a notch 312 on the side facing the second connecting block 510. Both opposite walls of the notch 312 are provided with limiting grooves 313. The first elastic member 320 is disposed in the limiting groove 313 and at least partially protrudes from the limiting groove 313 and is received in the notch 312. The second connecting block 510 has a protrusion 512 on the side facing the first connecting block 310. The protrusion 512 is at least partially received in the notch 312, and there is a gap between the surface of the protrusion 512 and the inner wall of the notch 312 to ensure the smoothness and stability of the sliding process of the first connecting block 310 relative to the second connecting block 510.

[0097] The protrusion 512 has a second elastic element 520 on the side facing the first elastic element 320, and the second elastic element 520 at least partially protrudes from the protrusion 512, so that the first elastic element 320 can abut against the second elastic element 520 to form a limiting structure during the sliding of the first connecting block 310 relative to the second connecting block 510. That is, during the rotation of the protruding rod 200 relative to the protruding rod sleeve 100, it can drive the movable cover plate 410 to move, and through the movable cover plate 410, it drives the first connecting block 310 and the first elastic element 320 to move synchronously. When the protruding rod 200 rotates at a preset angle, the first elastic element 320 abuts against the second elastic limit 520 and forms a limiting effect on the protruding rod 200 and the movable cover plate 410, thereby realizing the control of the water output.

[0098] like Figure 6 and Figure 7 As shown, in some embodiments of this application, the throttle valve core includes a housing 600 and a bottom housing 700.

[0099] The outer shell 600 is sleeved on the protruding rod sleeve 100, the bottom shell 700 is connected to the outer shell 600, and defines a receiving cavity between the bottom shell 700 and the outer shell 600. The movable cover plate 410, the first elastic limiting member 300, the second elastic limiting member 500, and the protruding rod sleeve 100 are respectively housed in the receiving cavity.

[0100] Furthermore, the connection method between the bottom shell 700 and the outer shell 600 includes any one of the following: snap-fit, adhesive, bolt connection, threaded connection, thermoforming connection, or integral molding, which can be specifically set according to the actual situation. In this embodiment, the bottom shell 700 and the outer shell 600 are fixedly connected to improve the stability and overall strength of the connection between the bottom shell 700 and the outer shell 600.

[0101] In this embodiment, the movable plate body 420 is disposed on the side of the movable cover plate 410 away from the protruding rod 200, and the movable plate body 420 is connected to the movable cover plate 410. The movable plate body 420 and the movable cover plate 410 are connected by snap-fit, adhesive or magnetic connection, so that the movable cover plate 410 can drive the movable plate body 420 to move synchronously during the movement.

[0102] In addition, the stationary piece 800 is disposed on the side of the moving piece body 420 away from the moving cover piece 410, and the stationary piece 800 is fixedly connected to the bottom shell 700, and the moving piece body 420 can slide relative to the stationary piece 800.

[0103] When the throttle valve core is in the closed state, the opening of the water passage cavity 421 in the moving plate body 420 is opposite to the mixing hole 830 of the stationary plate 800, and the opening of the water passage cavity 421 in the moving plate body 420 does not coincide with the first water inlet hole 810 and the second water inlet hole 820 of the stationary plate 800. It can be understood that the opening of the water passage cavity 421 is misaligned with the first water inlet hole 810 and the second water inlet hole 820 of the stationary plate 800, thus keeping the throttle valve core in the closed state.

[0104] When the protruding rod 200 rotates relative to the protruding rod sleeve 100, the protruding rod 200 drives the moving cover plate 410 to move, and the moving cover plate 410 drives the moving plate body 420 to move synchronously relative to the stationary plate 800, so that the first water inlet hole 810, the second water inlet hole 820 and the mixing hole 830 are respectively connected to the water passage cavity 421, thereby opening the throttle valve core. As the moving plate body 420 moves, the diameter of the first water inlet hole 810, the second water inlet hole 820 and the mixing hole 830 connected to the water passage cavity 421 gradually increases, thereby gradually increasing the water flow rate.

[0105] When the first elastic element 320 and the second elastic element 520 come into contact, they can limit the moving plate body 420, the moving cover plate 410 and the protruding rod 200, thereby controlling the water output by adjusting the diameter of the first water inlet hole 810 and the second water inlet hole 820 to communicate with the water passage cavity 421, so as to achieve the purpose of throttling.

[0106] Some embodiments of this application provide a water-using device, including the throttling valve core described in any of the above embodiments.
