[0019] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application, and cannot be understood as limiting the present application.

[0020] It should be noted that when an element is referred to as being "fixed to" another element, it may be directly on the other element or there may also be a centered element.

[0023] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art to which this application belongs. The terms used herein in the specification of the template are only for the purpose of describing specific embodiments and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0024] like Figures 1 to 7 As shown, some embodiments of the present application provide a throttling valve core, which is mainly used in faucets, showers, 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 resource waste, thereby optimizing the user's daily water needs and improving the user's usage experience.

[0025] The throttle valve core includes a moving plate 400, a stationary plate 800 and an elastic limiting structure.

[0026] The movable plate 400 and the stationary plate 800 are connected by sliding along a first direction to adjust the throttle valve core to switch between an open state and a closed state. It is understandable that the movable plate 400 can switch the throttle valve core from a closed state to an open state during the sliding process relative to the stationary plate 800 along the first direction, and similarly, the throttle valve core can also switch from an open state to a closed state.

[0027] In addition, the static plate 800 has a first water inlet hole 810, a second water inlet hole 820 and a mixing water hole 830, and the dynamic plate 400 is provided with a water passage cavity 421, and the water passage cavity 421 is connected to the mixing water hole 830, and the water passage cavity 421 can be connected to the first water inlet hole 810 and / or the second water inlet hole 820.

[0028] It should be noted that when the throttle valve core is in a closed state, the water passage cavity 421 is in communication with the water mixing hole 830, and the first water inlet hole 810 and the second water inlet hole 820 are not in communication with the water passage cavity 421. In some embodiments, when the throttle valve core is in an open state, the water passage cavity 421 is in communication with the water mixing hole 830, and the first water inlet hole 810 or the second water inlet hole 820 is in communication with the water passage cavity 421; in some embodiments, when the throttle valve core is in an open state, the water passage cavity 421 is in communication with the water mixing hole 830, and the first water inlet hole 810 and the second water inlet hole 820 are in communication with the water passage cavity 421.

[0029] In this embodiment, the first water inlet hole 810 is a hot water inlet hole, and the second water inlet hole 820 is a cold water inlet hole.

[0030] It can be understood that when the throttle valve core is in a closed state, the movable plate 400 moves along the first direction relative to the static plate 800, so that the first water inlet hole 810, the second water inlet hole 820 and the mixing water hole 830 are respectively connected to the water flow cavity 421, thereby opening the throttle valve core. As the movable plate 400 moves, the diameters of the first water inlet hole 810, the second water inlet hole 820 and the mixing water hole 830 connected to the water flow cavity 421 are gradually increased, thereby gradually increasing the water flow rate.

[0031] The elastic limiting structure is arranged on a side of the moving piece 400 away from the static piece 800 , and includes a first elastic limiting member 300 and a second elastic limiting member 500 which are movably connected.

[0032] In this embodiment, the first elastic limit member and the second elastic limit member 500 are configured as follows: when the movable plate 400 moves a preset distance relative to the static plate 800 along the first direction, the second elastic limit member 500 and the first elastic limit member 300 abut against each other to form an elastic limit for the movable plate 400, and control the caliber of the first water inlet hole 810 and / or the second water inlet hole 820 connected to the water passage cavity 421 respectively, so as to adjust the water flow rate flowing through the first water inlet hole 810 and / or the second water inlet hole 820, thereby achieving control of the water output, avoiding the movable plate 400 from sliding too far relative to the static plate 800, resulting in too much water output, thereby avoiding waste of water resources.

[0033] It is worth noting that since the first elastic limit member 300 and the second elastic limit member 500 are respectively elastic, when the user needs to increase the water consumption during water use, at this time, the user can increase the force acting on the movable plate 400. When the force applied by the user to the movable plate 400 is greater than the resistance generated by the mutual abutment between the first elastic limit member 300 and the second elastic limit member 500, the second elastic limit member 500 can move relative to the first elastic limit member 300 under the action of external force, and the movable cover plate 410 can slide relative to the static plate 800 again, thereby increasing the diameter of the first water inlet hole 810 and / or the second water inlet hole 820 connecting to the water passage cavity 421, thereby increasing the water output to meet the user's water demand and enhance the user's usage experience.

[0034] like Figure 2 As shown, in some embodiments of the present invention, the movable piece 400 includes a movable cover piece and a movable piece body 420. The movable piece body 420 is arranged on the side of the movable cover piece facing the static piece 800, and the movable piece body 420 is connected to the movable cover piece, that is, the movable cover piece can move synchronously with respect to the movable piece body 420.

[0035] like Figure 2 As shown, in some embodiments of the present invention, the throttle valve core includes a protruding rod sleeve 100 and a protruding rod 200 .

[0036] The convex rod sleeve 100 defines an active space 110, and partially accommodates the convex rod 200 in the active space 110, and the convex rod 200 is rotatably connected to the convex rod sleeve 100 to ensure the smoothness and stability of the convex rod 200 relative to the convex rod sleeve 100 during rotation. It is understandable that a portion of the convex rod 200 is located outside the active space 110.

[0037] Among them, the convex rod 200 has an adjusting end 210 and a connecting end 220, the connecting end 220 is accommodated in the activity space 110, and the convex rod 200 is rotatably connected to the convex rod sleeve 100, that is, the adjusting end 210 is located outside the activity space 110, so that the user can hold the adjusting end 210 to rotate and adjust the convex rod 200, thereby adjusting the water output.

[0038] The first elastic limiter 300 is arranged on the side of the convex rod sleeve 100 away from the adjustment end 210, and the connection method between the first elastic limiter 300 and the convex rod sleeve 100 includes any one of magnetic connection, bonding, clamping, threaded connection, and bolt connection, which can be specifically set according to actual conditions.

[0039] It can be understood that by detachably connecting the first elastic limit member 300 and the convex rod sleeve 100, it is convenient to install or replace the first elastic limit member 300 on the convex rod sleeve 100, so that different models of the first elastic limit member 300 can be replaced according to the actual usage of the user, thereby meeting the different needs of different users for water usage.

[0040] The movable cover piece 410 is slidably connected to the convex rod sleeve 100, and the movable cover piece 410 is movably connected to the connecting end 220, so that when the convex rod 200 rotates relative to the convex rod sleeve 100, the movable cover piece 410 can be driven by the connecting end 220 to slide synchronously relative to the convex rod sleeve 100, thereby realizing the adjustment of the output quantity.

[0041] The second elastic limiting member 500 is arranged on the side of the movable cover piece 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 when the movable cover piece 410 slides relative to the convex rod sleeve 100, the second elastic limiting member 500 slides synchronously relative to the first elastic limiting member 300.

[0042] It can be understood that the second elastic limiting member 500 and the movable cover plate 410 move synchronously.

[0043] In this embodiment, the second elastic limiting member 500 is configured as follows: when the convex rod 200 rotates 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 form a limiting effect on the movable cover piece 410 and the convex rod 200, so as to control the rotation angle of the convex rod 200 relative to the convex rod sleeve 100, and at the same time control the sliding position of the movable cover piece 410 relative to the convex rod sleeve 100, so as to achieve control of the water output, avoid the convex rod 200 from rotating at too large an angle, make the movable cover piece 410 slide too far relative to the convex rod sleeve 100, resulting in too much water output, thereby avoiding waste of water resources.

[0044] It is worth noting that since the first elastic limit member 300 and the second elastic limit member 500 are respectively elastic, when the user needs to increase the water consumption during the water use process, the user can rotate the convex rod 200. When the force applied by the user on the convex rod 200 is greater than the resistance generated by the mutual abutment between the first elastic limit member 300 and the second elastic limit member 500, the second elastic limit member 500 can move relative to the first elastic limit member 300 under the action of external force. That is, at this time, the rotation angle of the convex rod 200 relative to the convex rod sleeve 100 increases, and the movable cover piece 410 can slide relative to the convex rod sleeve 100 again, that is, the sliding distance of the movable cover piece 410 increases, thereby increasing the water output to meet the user's water demand and enhance the user's usage experience.

[0045] It should be noted that the preset angle described here refers to the preset angle at which the convex rod 200 rotates relative to the convex rod sleeve 100. The preset angle has a value range of 10° to 45°. It can be understood that the preset angle can be any value of 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 specifically set according to actual conditions.

[0046] It is worth noting that in this embodiment, when the axis of the convex rod 200 coincides with or is parallel to the axis of the convex rod sleeve 100, at this time, the rotation angle of the convex rod 200 relative to the convex rod sleeve 100 is 0°, and at the same time, the movable cover piece 410 is located at the initial position and can block the water flow. At this time, no water flows through the throttle valve core, that is, the regulating valve core is in a closed state. When the convex rod 200 rotates relative to the convex rod sleeve 100, at this time, the angle between the axis of the convex rod 200 and the axis of the convex rod sleeve 100 is greater than 0°, and the movable cover piece 410 moves relative to the convex rod sleeve 100. At this time, the water flow can pass through the throttle valve core, and the water flow through the throttle valve core increases as the distance that the movable cover piece 410 moves relative to the convex rod sleeve 100 increases. It can be understood that the larger the angle between the axis of the convex rod 200 and the axis of the convex rod sleeve 100, the greater the water flow through the throttle valve core.

[0047] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, the convex rod sleeve 100 includes a connecting tube 120 and a first connecting platform 130 , and the first connecting platform 130 is arranged on one side of the axial direction of the connecting tube 120 .

[0048] The connection method between the connecting tube 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 actual conditions.

[0049] In this embodiment, the connecting tube 120 and the first connecting platform 130 are integrally formed to enhance the overall strength and stability of the convex rod sleeve 100 .

[0050] In addition, the connecting tube 120 defines the movable space 110 , which passes through the connecting tube 120 along the axial direction of the connecting tube 120 , and a first guide groove 131 communicating with the movable space 110 is provided on a side of the first connecting platform 130 away from the connecting tube 120 .

[0051] It should be noted that the first guide groove 131 is used to provide guidance and limit the movable cover piece 410 during the movement process, so as to ensure the accuracy, stability and smoothness of the movable cover piece 410 during the movement process.

[0052] In this embodiment, a first mounting groove 132 for fixing the first elastic limiting member 300 is provided on the side of the first connecting platform 130 facing away from the connecting tube 120, and the groove wall of the first mounting groove 132 provides limiting and fixing functions for the first elastic limiting member 300 to ensure the stability of the connection between the first elastic limiting member 300 and the first connecting platform 130.

[0053] like Figure 2 As shown, in some embodiments of the present application, the first elastic limiting member 300 includes a first connecting block 310 and at least one first elastic member 320 .

[0054] It is understandable that the number of the first elastic members 320 can be one, two, or any number greater than two, and can be specifically set according to actual conditions.

[0055] The first connection block 310 is received in the first installation groove 132, that is, the first connection block 310 is connected to the groove wall of the first installation groove 132, and the first connection block 310 is provided with at least one first clamping groove 311 on the side facing the second elastic stopper 500. It can be understood that the number of the first clamping grooves 311 can be one, two or more than two, and can be specifically set according to actual conditions.

[0056] It should be noted that the number of the first slots 311 is equal to or greater than the number of the first elastic members 320 .

[0057] In this embodiment, the number of the first card slots 311 is equal to the number of the first elastic members 320, one of the first elastic members 320 is correspondingly arranged in one of the first card slots 311, and the first elastic member 320 at least partially protrudes from the first card slot 311, so that the part of the first elastic member 320 protruding from the first card slot 311 can abut against the second elastic limiting member 500 to form a limiting structure, so as to realize the limiting effect on the moving distance of the movable cover plate 410, thereby achieving the purpose of throttling.

[0058] like Figure 2 , Figure 3 and Figure 5 As shown, in this embodiment, the number of the first slot 311 and the number of the first elastic member 320 are one, respectively, 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 convex rod 200 rotates to a preset angle, at this time, the first elastic member 320 abuts against the second elastic limiting member 500 to limit the convex rod 200, so as to ensure the accuracy of the rotation angle of the convex rod 200, thereby ensuring the accuracy of the moving position of the movable cover plate 410, so as to ensure the accuracy of the water output control, thereby avoiding the waste of water resources and achieving the purpose of throttling.

[0059] In addition, in some embodiments of the present application, there are multiple first card slots 311 and multiple first elastic members 320 , and the multiple first card slots 311 are arranged at intervals along the sliding direction of the movable cover plate 410 , and each first elastic member 320 is clamped in a first card slot 311 .

[0060] It should be noted that, by providing multiple first slots 311 and multiple first elastic members 320, the convex rod 200 can achieve multi-level adjustment during rotation, that is, when the convex rod 200 rotates to a preset angle, the second elastic limit member 500 can abut against the first first elastic member 320, and when the convex rod 200 rotates to a preset angle again, the second elastic limit member 500 can abut against the second first elastic member 320, and so on, thereby achieving multi-level adjustment of the water output, allowing users to more conveniently adjust the water consumption according to their own needs during water use, which can not only achieve the purpose of saving water, but also enhance the user experience and convenience of use.

[0061] like Figure 2 , Figure 3 and Figure 5As shown, in some embodiments of the present application, a first guide platform 411 is provided on the side of the movable cover plate 410 facing the first connecting platform 130, the first guide platform 411 is accommodated 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 guiding and limiting functions to 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.

[0062] Among them, the first guide platform 411 is provided with a clearance groove 4111 on the side facing the convex rod 200, and the connecting end 220 is accommodated in the clearance groove 4111, and the connecting end 220 is movably connected to the groove wall of the clearance groove 4111, so that when the convex rod 200 rotates relative to the convex rod sleeve 100, the connecting end 220 rotates relative to the convex rod sleeve 100, and the connecting end 220 can drive the movable cover plate 410 to move synchronously during the rotation process, thereby adjusting the water output.

[0063] like Figure 2 and Figure 5 As shown, in some embodiments of the present application, the side of the movable cover plate 410 facing the first connecting platform 130 is provided with a second installation groove 412 for fixing the second elastic limiting member 500. The connection method between the second elastic limiting member 500 and the groove wall of the second installation groove 412 includes any one of a snap connection, a magnetic connection, and an adhesive connection, which can be specifically set according to actual conditions.

[0064] It can be understood that by detachably connecting the second elastic limiting member 500 to the groove wall of the second installation groove 412 , it is convenient to install or replace the second elastic limiting member 500 .

[0065] like Figure 2 and Figure 3 As shown, in some embodiments of the present application, the second elastic limiting member 500 includes a second connecting block 510 and at least one second elastic member 520 .

[0066] It is understandable that the number of the second elastic members 520 can be one, two, or any number above two, and can be specifically set according to actual conditions.

[0067] The second connection block 510 is received in the second installation groove 412, that is, the second connection block 510 is connected to the groove wall of the second installation groove 412, and the second connection block 510 is provided with at least one second clamping groove 511 on the side facing the first elastic stopper 300. It can be understood that the number of the second clamping grooves 511 can be one, two or more than two, and can be specifically set according to actual conditions.

[0068] It should be noted that the number of the second slots 511 is equal to or greater than the number of the second elastic members 520 .

[0069] In this embodiment, the number of the second slots 511 is equal to the number of the second elastic members 520, one second elastic member 520 is correspondingly arranged 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, so as to realize the limiting effect on the moving distance of the movable cover plate 410, thereby achieving the purpose of throttling.

[0070] In this embodiment, the second elastic member 520 is configured such that when the convex rod 200 rotates a preset angle, the second elastic member 520 abuts against the first elastic member 320 to limit the movable cover plate 410 and the convex rod 200, thereby controlling the water output.

[0071] In this embodiment, the number of the second slot 511 and the number of the second elastic member 520 are respectively one, so that the first elastic member 320 provides a limiting effect on the second elastic member 520. It can be understood that when the convex rod 200 rotates to a preset angle, at this time, the first elastic member 320 abuts against the second elastic member 520 to form a limit on the convex rod 200, so as to ensure the accuracy of the rotation angle of the convex rod 200, thereby ensuring the accuracy of the moving position of the movable cover plate 410, so as to ensure the accuracy of the control of the water output, thereby avoiding the waste of water resources and achieving the purpose of throttling.

[0072] like Figure 4 and Figure 5 As shown, in some embodiments, a notch 312 is provided on the side of the first connecting block 310 facing the second connecting block 510, and two opposite wall surfaces of the notch 312 are provided with limiting grooves 313, the first elastic member 320 is arranged in the limiting groove 313, and the first elastic member 320 at least partially protrudes from the limiting groove 313 and is accommodated in the notch 312, and a protrusion 512 is provided on the side of the second connecting block 510 facing the first connecting block 310, and the protrusion 512 is at least partially accommodated 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 first connecting block 310 during sliding relative to the second connecting block 510.

[0073] Among them, a second elastic member 520 is provided on the side of the protrusion 512 facing the first elastic member 320, and the second elastic member 520 at least partially protrudes from the protrusion 512, so that the first elastic member 320 can abut against the second elastic member 520 to form a limiting structure during the sliding process of the first connecting block 310 relative to the second connecting block 510. That is, the convex rod 200 can drive the movable cover plate 410 to move during the rotation process relative to the convex rod sleeve 100, and the first connecting block 310 and the first elastic member 320 are driven to move synchronously through the movable cover plate 410. When the convex rod 200 rotates to a preset angle, the first elastic member 320 abuts against the second elastic limit 520, and forms a limiting effect on the convex rod 200 and the movable cover plate 410, thereby realizing the control of the water output.

[0074] like Figure 6 and Figure 7 As shown, in some embodiments of the present application, the throttle valve core includes an outer shell 600 and a bottom shell 700 .

[0075] Among them, the outer shell 600 is sleeved on the convex rod sleeve 100, the bottom shell 700 is connected to the outer shell 600, and an accommodating cavity is defined between the bottom shell 700 and the outer shell 600, and the movable cover piece 410, the first elastic limiter 300, the second elastic limiter 500, and the convex rod sleeve 100 are respectively accommodated in the accommodating cavity.

[0076] In addition, the connection between the bottom shell 700 and the outer shell 600 includes any one of clamping, bonding, bolting, threading, hot-melt connection, and integral molding, which can be specifically set according to actual conditions. 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.

[0077] In this embodiment, the movable plate body 420 is arranged 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 snapping, bonding or magnetic connection, so that the movable cover plate 410 can drive the movable plate body 420 to move synchronously during the movement.

[0078] In addition, the static piece 800 is disposed on a side of the dynamic piece body 420 away from the dynamic cover piece 410 , and the static piece 800 is fixedly connected to the bottom shell 700 , and the dynamic piece body 420 can slide relative to the static piece 800 .

[0079] When the throttle valve core is in the closed state, the opening of the water-passing cavity 421 in the moving plate body 420 is opposite to the water-mixing hole 830 of the static plate 800, and the opening of the water-passing cavity 421 of the moving plate body 420 does not overlap with the first water inlet hole 810 and the second water inlet hole 820 of the static plate 800. It can be understood that the opening of the water-passing cavity 421 and the first water inlet hole 810 and the second water inlet hole 820 of the static plate 800 are all in a misaligned state, so that the throttle valve core is in the closed state.

[0080] When the convex rod 200 rotates relative to the convex rod sleeve 100, the movable cover plate 410 is driven to move through the convex rod 200, and the movable plate body 420 is driven to move synchronously relative to the static plate 800 through the movable cover plate 410, so that the first water inlet hole 810, the second water inlet hole 820 and the mixing water hole 830 are respectively connected to the water passage cavity 421, thereby opening the throttling valve core, and with the movement of the movable plate body 420, the diameters of the first water inlet hole 810, the second water inlet hole 820 and the mixing water hole 830 respectively connected to the water passage cavity 421 are gradually increased, thereby gradually increasing the water flow rate.

[0081] When the first elastic member 320 and the second elastic member 520 are in contact with each other, they can form a limiting effect on the movable plate body 420, the movable cover plate 410 and the protruding rod 200, so that the first water inlet hole 810 and the second water inlet hole 820 are respectively connected to the water passage cavity 421 with respect to the diameter, thereby controlling the water output to achieve the purpose of throttling.
