[0004] To solve the above technical problems, the technical scheme adopted by the present application is as follows: a flow regulating device, comprising a mobile rod for reciprocating and switching different water outlet flow channels, a flow regulating member is arranged on the circumference of the mobile rod and protrudes outward, and the mobile rod is rotated to drive the flow regulating member to rotate and regulate the flow of the water outlet flow channel.

[0005] The beneficial effects of the present application are as follows: when in use, the mobile rod is pressed to control the switching of the water outlet flow channel, so that the user can select the water outlet position according to the needs, such as upper water outlet and lower water outlet. At the same time, the flow of a specific water outlet can be freely regulated by rotating the mobile rod to drive the flow regulating member to rotate, especially in a device provided with an upper water outlet, which can regulate the water flow size to facilitate the user's daily washing.

[0041] To describe the technical solutions in the present application in detail, the purposes and effects achieved by the present application are explained below in conjunction with the embodiments and the accompanying drawings.

[0042] The present application provides a flow regulating device, comprising a moving rod reciprocally moving to switch different water outlet channels, a flow regulating member is arranged on the moving rod in a circumferential direction, and the moving rod rotates to drive the flow regulating member to rotate and regulate the flow of the water outlet channel.

[0043] From the above description, the flow regulating device has the following advantages: when in use, the moving rod is pressed to control the switching of the water outlet channel, so that the user can select the water outlet position according to the needs, such as upper water outlet and lower water outlet. Meanwhile, the flow of a certain water outlet can be freely regulated by rotating the moving rod to drive the flow regulating member to rotate, especially in the device provided with the upper water outlet, the water flow can be regulated to facilitate the user's daily washing.

[0044] Further, in the flow regulating device, the flow regulating member comprises a regulating circular table arranged on the moving rod in a circumferential direction, a notch is arranged on the circumferential surface of the regulating circular table, and the circumferential surface of the regulating circular table faces and closes the corresponding water outlet channel.

[0045] From the above description, the regulating circular table is arranged on the moving rod, the notch is arranged on the regulating circular table, the circumferential surface of the regulating circular table faces and closes the corresponding water outlet channel, and the water flow flows into the water outlet channel closed by the circumferential surface of the regulating circular table through the notch. When the regulating circular table is rotated, the notch faces the corresponding water outlet channel, and the water flow in the water outlet channel flows normally. When the regulating circular table is rotated again, the space between the notch and the corresponding water outlet channel is reduced, the circumferential surface of the regulating circular table gradually closes the corresponding water outlet channel, and the water flow in the water outlet channel gradually decreases.

[0046] Further, in the flow regulating device, the flow regulating member comprises a regulating circular table arranged on the moving rod in a circumferential direction, a notch is arranged on the circumferential surface of the regulating circular table, and the circumferential surface of the regulating circular table faces and closes the corresponding water outlet channel. A notch block is arranged on the side wall of the water outlet channel.

[0047] From the above description, the regulating circular table is arranged on the moving rod, the notch is arranged on the regulating circular table, the circumferential surface of the regulating circular table faces and closes the corresponding water outlet channel together with the notch block fixedly arranged on the side wall, and the water flow flows into the water outlet channel closed by the circumferential surface of the regulating circular table through the notch. When the regulating circular table is rotated, the notch is not blocked by the notch block, and the water flow in the water outlet channel flows normally. When the regulating circular table is rotated again, the notch gradually approaches the notch block, the space between the notch and the corresponding water outlet channel is reduced, the circumferential surface of the regulating circular table gradually closes the corresponding water outlet channel, and the water flow in the water outlet channel gradually decreases.

[0048] Further, in the flow regulating device, the diameter of the regulating cone decreases in sequence along the circumferential direction, the central angle corresponding to the circumferential length is 90°, and then increases in sequence, the central angle corresponding to the circumferential length is 90°.

[0049] As can be seen from the above description, the diameter of the regulating cone decreases in sequence along the circumferential direction and then increases in sequence, so that the regulating cone has the shape of long and narrow at both ends and wide and flat at both ends. When the regulating cone is arranged to face and close the corresponding water outlet channel, the narrow and long end of the regulating cone serves as a closed end, and the wide and flat end serves as a flow-through end. That is, when the regulating cone is rotated so that the wide and flat end faces the corresponding water outlet channel, the space between the water outlet channel and the regulating cone is the largest, and the water outlet flow of the water outlet channel is the largest. The regulating cone is rotated again, and the narrow and long end faces the water outlet channel slowly, the space between the water outlet channel and the regulating cone decreases, and the water outlet flow of the water outlet channel decreases.

[0050] When the regulating cone is arranged to face and close the corresponding water outlet channel together with the notch plug arranged on the side wall, the narrow and long end of the regulating cone serves as a closed end, and the wide and flat end serves as a flow-through end. That is, when the regulating cone is rotated so that the longest diameter of the wide and flat end is parallel to the notch plug, the space between the water outlet channel and the regulating cone is the largest, the area of the water outlet channel closed by the notch plug and the surface of the regulating cone is the smallest, and the water outlet flow of the water outlet channel is the largest. The regulating cone is rotated again, and the narrow and long end is rotated slowly, the contact area between the narrow and long end and the notch plug decreases, the area of the water outlet channel closed by the notch plug and the surface of the regulating cone gradually increases, and the water outlet flow of the water outlet channel decreases.

[0051] Further, in the flow regulating device, two notches are symmetrically arranged on the regulating cone, and the cross section of the notch along the axial direction of the regulating cone is L-shaped.

[0052] As can be seen from the above description, the two notches are symmetrically arranged to prevent the water outlet flow from being too small or to prevent the water outlet flow from being blocked by water scale when used for a long time. When the regulating cone is rotated so that the L-shaped notch faces the corresponding water outlet channel, the space between the water outlet channel and the regulating cone is the largest, and the water outlet flow of the water outlet channel is the largest. The regulating cone is rotated again, and the non-notch circumferential surface of the regulating cone gradually closes the corresponding water outlet channel, and the water outlet flow of the water outlet channel decreases.

[0053] Further, in the flow regulating device, the moving rod includes a switching cone extending outward in the circumferential direction of the moving rod, and the switching cone reciprocally moves to switch the sealing of different water outlet channels.

[0054] As can be seen from the above description, the moving member reciprocally moves the switching cone extending outward in the circumferential direction to switch the sealing of the water outlet channel.

[0055] Further, the flow regulating device has a groove around the shaft of the switching cone, and a sealing rubber ring is arranged in the groove.

[0056] As described above, the switching cone has a groove, and a sealing rubber ring is arranged in the groove to move and close different water outlets.

[0057] Further, the flow regulating device has a water inlet channel and a distribution chamber, and the water outlet channel includes a first channel and a second channel.

[0058] The distribution chamber is provided with a first channel inlet connected to the first channel, and a second channel inlet connected to the second channel.

[0059] The flow regulating device further includes a switching spring, and the switching cone is arranged in the middle of the moving rod.

[0060] One end of the moving rod is a pressing end, and the other end is a placing end. The first channel is provided with a first accommodating cavity near the first channel inlet to accommodate the pressing end. The second channel is provided with a second accommodating cavity near the second channel inlet to accommodate the placing end.

[0061] The switching spring is sleeved on the placing end of the moving rod, one end of the switching spring abuts against the switching cone, and the other end abuts against the side wall of the second accommodating cavity.

[0062] As described above, when the pressing end is not pressed, the switching spring remains in a released state, the sealing rubber ring on the switching cone abuts against the edge of the water inlet away from one end of the switching spring, the second channel is closed, and the water inlet channel is connected to the first channel. When the pressing end is pressed, the switching spring is compressed, the sealing rubber ring on the switching cone abuts against the edge of the water inlet near one end of the switching spring, the first channel is closed, and the second channel is connected to the water inlet channel. Because the water flow fills the channel and exerts a reaction force on the switching cone supporting the switching spring, the switching spring is prevented from releasing and remains in a compressed state. When the water flow is closed, the switching spring is released.

[0063] Further, the flow regulating device has a water outlet channel including an upward water spraying channel opposite to the direction of gravity.

[0064] As described above, the water spraying channel is arranged, and the user can switch to the channel to spray upward water through the water spraying channel when needed, such as washing face and rinsing mouth.

[0065] Further, the flow regulating device has a multifunctional bubbler at the end of the second channel.

[0066] As can be seen from the above description, an aerator is set at the end of the first flow channel, so that the water output pattern can be selected. Taking the existing multi-functional aerators on the market as an example, the water output patterns include needle-shaped water, bubble water and spray water.

[0067] Example 1

[0068] like Figure 1 As shown, the flow regulating device of this embodiment includes a moving rod 20, a flow regulating component 30, and a water outlet channel 70.

[0069] The movable rod 20 is movable back and forth and rotated within the water outlet channel 70. The movable rod 20 can be a valve core as described in the background art. Its body has a sealing element for the water outlet channel 70, namely a flange placed between the upper water outlet chamber and the lower water outlet chamber. The movement of the movable rod drives the sealing element to move back and forth to switch between different water outlet channels 70.

[0070] Based on the above structure, a flow regulating component 30 is also provided on the movable rod 20. The movable rod 20 moves to the corresponding water outlet channel 70 and controls its water output. At this time, the movable rod 20 can rotate to drive the flow regulating component 30 to rotate and adjust the water output of the water outlet channel 70. The flow regulating component 30 includes an adjusting frustum 32 that extends circumferentially from the movable rod 20. The circumferential surface of the adjusting frustum 32 faces and closes the water outlet channel 70. A notch 31 is also provided on the circumferential surface of the adjusting frustum 32, through which water can flow into the water outlet channel 70 on the other side.

[0071] like Figure 1 and Figure 2 As shown, when the moving rod 20 is rotated, the moving rod 20 drives the adjusting platform 32 to rotate so that the notch 31 faces the water outlet channel 70 on the other side, and the water flows normally. At this time, the water outlet channel 70 has the largest water output.

[0072] like Figure 3 and Figure 4 As shown, when the moving rod 20 continues to rotate, the moving rod 20 causes the adjusting platform 32 to rotate, reducing the relative space between the notch 31 and the water outlet channel 70 on the other side. The circumferential surface of the adjusting platform 32 gradually closes the water outlet channel 70, and the water flow in the water outlet channel 70 gradually decreases. Until the circumferential surface of the adjusting platform 32 completely closes the water outlet channel 70, the water flow in the water outlet channel 70 is at its minimum.

[0073] Example 2

[0074] like Figure 5 As shown, the flow regulating device of this embodiment includes a moving rod 20, a flow regulating component 30, and a water outlet channel 70.

[0075] The mobile rod 20 is movably and rotatably arranged in the water outlet channel 70. The mobile rod 20 can be a valve core as in the background art, and a sealing member of the water outlet channel 70, i.e. a flange arranged between the upper water outlet cavity and the lower water outlet cavity, is arranged on the body of the mobile rod 20. The mobile rod 20 moves to drive the sealing member to reciprocate to switch different water outlet channels 70.

[0076] On the basis of the above structure, the mobile rod 20 is further provided with a flow adjusting member 30. When the mobile rod 20 moves to the corresponding water outlet channel 70 and controls the water outlet thereof, the mobile rod 20 can rotate to drive the flow adjusting member 30 to rotate and adjust the water outlet amount of the water outlet channel 70. The flow adjusting member 30 comprises an adjusting circular table 32 extending and protruding in the circumferential direction of the mobile rod 20. The circular surface of the adjusting circular table 32 faces and closes the water outlet channel 70. The peripheral surface of the adjusting circular table 32 is further provided with a gap 31. Water flow can flow into the water outlet channel 70 on the other side through the gap 31. The gap 31 is further provided with a gap blocking block 33 arranged in front of the adjusting circular table 32. The gap blocking block 33 closes part of the water outlet channel 70 and the gap 31.

[0077] As shown in Figure 5 and Figure 6 , when the mobile rod 20 is rotated, the mobile rod 20 drives the adjusting circular table 32 to rotate to make the gap 31 away from the gap blocking block 33, and the water outlet channel 70 on the other side is connected. At this time, the water outlet amount of the water outlet channel 70 is the largest.

[0078] As shown in Figure 7 and Figure 8 , when the mobile rod 20 is continuously rotated, the mobile rod 20 drives the adjusting circular table 32 to rotate, and the gap blocking block 33 gradually closes the gap 31. The connecting space of the gap 31 and the water outlet channel 70 on the other side is reduced, and the water flow of the water outlet channel 70 is gradually reduced. Until the gap blocking block 33 completely closes the gap 31 and the circular surface of the adjusting circular table 32 closes the water outlet channel 70, at this time, the water outlet amount of the water outlet channel 70 is the smallest.

[0079] Embodiment Three

[0080] As shown in Figure 10 , the flow adjusting device of the first embodiment comprises a mobile rod 20, a flow adjusting member 30 and a water outlet channel 70.

[0081] The mobile rod 20 is movably and rotatably arranged in the water outlet channel 70. The mobile rod 20 can be a valve core as in the background art, and a sealing member of the water outlet channel 70, i.e. a flange arranged between the upper water outlet cavity and the lower water outlet cavity, is arranged on the body of the mobile rod 20. The mobile rod 20 moves to drive the sealing member to reciprocate to switch different water outlet channels 70.

[0082] On the basis of the above structure, the mobile rod 20 is further provided with a flow adjusting member 30, the mobile rod 20 is moved to correspond to the water outlet channel 70 and controls the water outlet thereof. At this time, the mobile rod 20 can be rotated to drive the flow adjusting member 30 to rotate and adjust the water outlet amount of the water outlet channel 70. The flow adjusting member 30 comprises an adjusting circular table 32 which is projected and extends in the circumferential direction of the mobile rod 20, and the circular surface of the adjusting circular table 32 faces the water outlet channel 70. As shown in Figure 9 , the diameter length of the adjusting circular table 32 is sequentially reduced along the circumferential direction, the corresponding central angle of the circumferential length is 90°, and then is sequentially increased, the corresponding central angle of the circumferential length is 90°. The change of the diameter of the adjusting circular table 32 makes the adjusting circular table 32 have the shape of being long and narrow at both ends and wide and flat at both ends. The long and narrow end of the adjusting circular table 32 is used as a closed end, and the wide and flat end is used as a flow-through end. The water outlet channel 70 is further provided with a notch block 33 in front of the adjusting circular table 32, and the notch block 33 closes part of the water outlet channel 70.

[0083] As shown in Figure 10 and Figure 11 , when the mobile rod 20 is rotated, the mobile rod 20 drives the adjusting circular table 32 to rotate, so that the longest diameter of the wide and flat end is parallel to the notch block 33, at this time, the area closed by the circular surface of the adjusting circular table 32 and the notch block 33 is the smallest, and the water outlet amount of the water outlet channel 70 is the largest.

[0084] As shown in Figure 12 and Figure 13 , when the mobile rod 20 is continuously rotated, the mobile rod 20 drives the adjusting circular table 32 to rotate, so that the long and narrow end is slowly rotated, the contact area between the long and narrow end and the notch block 33 is reduced, the area closed by the notch block 33 and the circular surface of the adjusting circular table 32 is gradually increased, and the water outlet amount of the water outlet channel 70 is reduced.

[0085] According to the different cross-sectional areas of the water outlet channel 70 which can be closed by different notch blocks 33, in the embodiment, the positions where the adjusting circular table 32 is rotated to the maximum and minimum water outlet amount of the water outlet channel 70 are also different, that is, the size of the water outlet amount of the water outlet channel 70 is only related to the size of the cross-sectional area of the water outlet channel 70 closed by the circular surface of the adjusting circular table 32 and the notch block 33, so the positions where the maximum and minimum water outlet amount of the water outlet channel 70 appears in the embodiment are not fixed.

One end of the spring 52 is sleeved on the protruding column at the top of the valve cavity 56 and the other end is arranged in the groove at the bottom of the button shaft 54. The rubber water block 53 is slidably arranged in the valve sleeve 51 and sleeved on the lower end of the button shaft 54. When the spring 52 is not compressed, the rubber water block 53 is away from the pause water inlet 84 and the pause water outlet 85, and the water inlet channel 110 is communicated. When the spring 52 is compressed, the rubber water block 53 blocks the pause water inlet 84 and the pause water outlet 85 at the same time, and the water inlet channel 110 is closed. The button 55 is arranged at the end of the button shaft 54 away from the rubber water block 53.

[0099] Meanwhile, the pause water device 50 is also a reset device. When the button 55 is pressed, the spring 52 is compressed, the rubber water block 53 blocks the pause water inlet 84 and the pause water outlet 85 at the same time, and the water inlet channel 110 is closed. Since there is no water flow, the switching spring 21 remains in the uncompressed state, and the sealing rubber ring 221 blocks the second flow channel 72, and the water outlet state of the water outlet device changes to be watered by the first flow channel 71.

[0100] As shown, Figure 17 in use, when the pressing shell 224 is not pressed, the channel between the water inlet channel 110 and the first flow channel 71 is blocked by the sealing rubber ring 221 under the action of the switching spring 21, the water inlet channel 110 is communicated with the second flow channel 72, and the water flow flows out from the water inlet channel 110 along the second flow channel 72.

[0101] As shown, Figure 20 when the pressing shell 224 is pressed, the switching spring 21 is compressed, the channel between the water inlet channel 110 and the second flow channel 72 is blocked by the sealing rubber ring 221, the water inlet channel 110 is communicated with the first flow channel 71, and the water flow flows out from the water inlet channel 110 along the water spraying channel 90 of the first flow channel 71. The switching spring 21 remains compressed due to the water flow.

[0102] As shown, Figure 21 , Figure 22 at this time, the finger presses the hemispherical recess 226 of the pressing shell 224 and rotates, the adjusting circular table 32 of the flow adjusting member 30 rotates, with the gap between the notch 31 and the first water outlet 83 gradually reducing, the contact area between the non-notch 31 part of the adjusting circular table 32 and the first water outlet 83 increases, the opening area of the first water outlet 83 decreases, and the water outlet amount of the water spraying channel 90 decreases.

[0103] When the press shell 224 is rotated to the limit state, the gap between the notch 31 and the first water outlet 83 is the largest and the smallest, respectively, that is, the water outlet of the water spray channel 90 is the largest and the smallest.

[0104] In summary, the flow regulating device provided by the application includes a moving rod that switches different water outlets by reciprocating movement, a flow regulating member is arranged on the circumference of the moving rod and protrudes outward, and the moving rod rotates to drive the flow regulating member to rotate and regulate the flow of the water outlet. In use, the moving rod is pressed to control the switching of the water outlet, so that the user can select the water outlet position according to the requirement, such as the upper water outlet and the lower water outlet. At the same time, the flow regulating member can be rotated to freely select the water flow of a certain water outlet, such as the size of the upper water outlet, which is convenient for the user to wash and rinse daily.

[0105] The above description is only an embodiment of the application, and does not limit the patent scope of the application. Any equivalent transformation or direct or indirect application in the related technical field based on the content of the specification and drawings is also included in the patent protection scope of the application.
