[0062] Example 1

[0063] refer to Figure 1-Figure 6 , this embodiment provides a push-switch water rotary flow regulating valve core, including: a valve body 1, a push operating member 2, a rotary regulating member 3 and a center rod 4;

[0064] The valve body 1 has a water inlet 11 and a water outlet 12, and a first flow channel 13 and a second flow channel 14 connected between the water inlet 11 and the water outlet 12;

[0065] The valve body 1 is provided with a first sealing portion and a second sealing portion at different positions; the pressing operating member 2 is used to drive the center rod 4 and the first sealing portion to move between the first position and the second position; when the center rod 4 and the first sealing portion are at the first position, the first sealing portion seals the first flow channel 13, and the center rod 4 cooperates with the second sealing portion to seal the second flow channel 14; when the center rod 4 and the first sealing portion are at the second position, the first sealing portion opens the first flow channel 13, and the center rod 4 releases the cooperation with the second sealing portion to open the second flow channel 14;

[0066] The rotary adjusting member is used to control the first sealing member to move between the second position and the third position to adjust the water outlet flow of the first flow channel 13 through a linkage control mechanism when the center rod 4 and the first sealing member are in the second position, and the third position is between the second position and the first position; in the process of the rotary adjusting member controlling the first sealing member to move between the second position and the third position through the linkage control mechanism, the first sealing member has 1, 2, 3, 4, 5..., n positions, and the first sealing member can stay at any one of the n positions according to the control of the rotary adjusting member, and when staying at different positions, the water outlet flow of the first flow channel 13 will change, thereby realizing stepless flow adjustment; when the center rod 4 and the first sealing member are in the third position, the first sealing member seals the first flow channel 13, and the second flow channel 14 remains connected with the water inlet 11.

[0067] The above-mentioned push-switch water-rotating flow regulating valve core is provided with a second flow channel 14. During the process of rotating the flow regulating, the first flow channel 13 can be rotated to adjust the size, and the second flow channel 14 remains in a normally open fixed non-adjustable flow state, and the two water channels merge and discharge, so that the minimum flow of the product is determined by the second flow channel 14. When the first flow channel 13 is rotated to adjust the flow of the first flow channel 13 to zero, the minimum flow of the valve core is the flow of the second flow channel 14, and the flow is stable, so that the minimum flow value of the product can be more accurately controlled in a smaller flow range during mass production, thereby increasing the product flow control accuracy and stability.

[0068] To realize water switching, the first sealing part is a pilot valve, including a pilot valve seat 15 and a diaphragm 16 fixed on the pilot valve seat 15, and the second sealing part is a first sealing ring 141 arranged in the second flow channel 14. The pilot valve is provided with a pressure relief hole 161 for the central rod 4 to pass through, and a water replenishment port 162 with a diameter smaller than the pressure relief hole 161; the pilot valve and the middle seat 18 of the valve body 1 form a pressure chamber 163; the central rod 4 is provided with a first part 41 and a second part 42, and the diameter of the second part 42 is larger than the first part 41;

[0069] When the center rod 4 is in the first position, the second part 42 is located in the pressure relief hole 161 and seals the pressure relief hole 161. Water from the outside enters the pressure chamber 163 through the water replenishment port 162, causing the pressure in the pressure chamber 163 to increase. The pilot valve moves downward under the pressure in the pressure chamber 163, and the pilot valve seat 15 on the pilot valve moves downward to drive the diaphragm 16 to deform downward, thereby sealing the first flow channel 13 and realizing water shut-off of the first flow channel 13. When the center rod 4 is in the second position, the first part 41 is located in the pressure relief hole 16 1, since the diameter of the first part 41 is relatively small, there is a gap between the first part 41 and the pressure relief hole 161, so that the pressure relief hole 161 is opened, and the water in the pressure chamber 163 flows out from the pressure relief hole 161, causing the water pressure in the pressure chamber 163 to drop, and the pressure outside the pressure chamber 163 is greater than the pressure inside the pressure chamber 163. At this time, the pilot valve moves upward under the pressure outside the pressure chamber 163, and the pilot valve drives the diaphragm 16 fixed in the pilot valve seat 15 to deform upward, thereby releasing the seal of the first flow channel 13, and realizing the boiling of water in the first flow channel 13.

[0070] In addition, in the present embodiment, the second flow channel 14 is located below the first flow channel 13; when the pilot valve moves downward to drive the diaphragm 16 fixed on the pilot valve seat 15 to deform downward to seal the first flow channel 13, it will not affect the connectivity of the second flow channel 14, thus ensuring that the second flow channel 14 is always in an open state during the flow rate adjustment process.

[0071] In order to close the second flow channel 14 when the center rod 4 is in the first position, the center rod 4 is further provided with a third portion 43 at one end of the first portion 41 away from the second portion 42, and a first sealing ring 141 is provided on the inner wall of the second flow channel 14; when the center rod 4 is in the third position, the third portion 43 is away from the first sealing ring 141, and the second flow channel 14 is in an open state. When the center rod 4 continues to move downward from the third position to the first position, the third portion seals with the first sealing ring 141 to close the second flow channel 14, thereby stopping the water flow of the entire valve core.

[0072] To realize the water on / off operation, the center rod 4 can be moved from the first position to the second position, or from the second position to the first position, and the pressing operation member 2 is required to drive the movement of the center rod 4. Specifically, the pressing operation member 2 includes a handle 21, a boss 22 is fixedly arranged inside the handle 21; a water-opening spring 45 is arranged outside the center rod 4;

[0073] The handle 21 is located at a high position or a low position under the action of an external force. When the handle 21 is located at a low position, the boss 22 abuts against the center rod 4 to drive the center rod 4 to the first position, and the center rod 4 squeezes the water-opening spring 45 to accumulate elastic restoring force; when the handle 21 is located at a high position, the boss 22 is separated from the center rod 4, and the center rod 4 moves to the second position driven by the restoring force of the water-opening spring 45. To achieve the reset of the handle 21, the handle 21 also needs to be connected to a reset spring 23. When the handle 21 is located at a low position, the reset spring 23 accumulates elastic restoring force.

[0074] The above structure can realize the operation of turning off and turning on the water. Then, to realize the flow adjustment operation in the state of turning on the water, it is necessary to rely on the rotating adjustment member 3 and the linkage control mechanism. In this embodiment, the linkage control mechanism is the guide seat 5; when the center rod position 4 is in the second position, the guide seat 5 and the center rod 4 are linked and matched along the direction from the second position to the third position; the guide seat 5 and the rotating adjustment member 3 are reversed to reverse the rotation of the rotating adjustment member 3 to the movement of the center rod 4 along the second position to the third position. In this way, the function of the guide seat 5 is to reverse the rotation of the rotating adjustment member 3 through the guide seat 5 to the axial movement of the center rod 4 through the reversed cooperation between the guide seat 5 and the rotating adjustment member 3. Thereby, when the center rod 4 is in the second position, the guide seat 5 and the center rod 4 are linked and matched along the direction from the second position to the third position. As long as the user rotates the rotating adjustment member 3, the center rod 4 can be driven to move in the direction from the second position to the third position.

[0075] To achieve flow adjustment, the water output of the first flow channel 13 must gradually decrease during the process of the center rod 4 moving from the second position to the third position. Therefore, the center rod 4 is also provided with a transition portion 44 between the first portion 41 and the second portion 42, and the diameter of the transition portion 44 gradually increases from one end close to the first portion 41 to the other end; in this way, when the center rod 4 moves from the second position to the third position, the transition portion 44 will gradually enter the pressure relief hole 161, so that the water flow area of ​​the pressure relief hole 161 gradually decreases, so that the pressure in the pressure chamber 163 will gradually increase, so that the pilot valve moves downward, driving the diaphragm 16 to deform downward, so that the distance between the diaphragm 16 and the first flow channel 13 becomes smaller, and the water output flow also decreases accordingly; when the center rod 4 moves to the third position, the second portion 42 is located in the pressure relief hole 161 and seals the pressure relief hole 161, and the diaphragm 16 seals the first flow channel 13 under the pressure in the pressure chamber 163, and closes the first flow channel 13. At this time, only the second flow channel 14 flows water, reaching the minimum flow rate of the valve core, and the flow rate is stable.

[0076] In this embodiment, since the guide seat 5 is covered outside the center rod 4, in order to allow the boss 22 to pass through the guide seat 5 to contact the center rod 4, a clearance opening 51 for the pressing operating member 2 to pass through is provided at the top of the guide seat 5, and the inner wall of the clearance opening 51 extends a limit surface 52 radially inward, and the upper end of the center rod 4 extends a limit matching surface 46 radially outward. When the center rod 4 is in the second position, the limit surface 52 abuts against the limit matching surface 46. In this way, when the water-opening spring 45 releases the elastic reset force, the upward movement position of the center rod 4 will be limited by the limit surface 52 and the limit matching surface 46, so that the center rod 4 can be accurately reset to the second position.

[0077] To achieve the reversing cooperation between the rotary adjusting member 3 and the guide seat 5, the rotary adjusting member 3 in this embodiment is sleeved outside the guide seat 5, and the guide seat 5 extends radially outward to form a lug 53 that abuts and cooperates with the lower end surface of the rotary adjusting member 3, and the lower end surface of the rotary adjusting member 3 is a slope 31 that gradually rises along the rotation direction; in this way, when the rotary adjusting member 3 rotates relative to the guide seat 5, the lug 53 on the guide seat 5 will move to different positions of the slope 31, for example, when the lug 53 moves to the highest position of the slope 31, the center rod 4 is located at the second position, and when the lug 53 moves to the lowest position of the slope 31, the center rod 4 is located at the third position. When the lug 53 moves from the highest position to the lowest position of the slope 31, an extrusion force will be generated between the slope 31 and the lug 53 to drive the guide seat 5 to move downward, and at this time, the guide seat 5 drives the center rod 4 to squeeze the water-opening spring 45. When the lug 53 moves from the highest position to the lowest position of the inclined surface 31 , the boiling water spring 45 releases its elastic restoring force to drive the guide seat 5 and the center rod 4 to move upward.

[0078] To form the pressure chamber 163, the valve body 1 further includes a middle seat 18. The middle seat 18 and the diaphragm 16 define the pressure chamber 163. The middle seat 18 is provided with a second clearance channel 181 for the center rod 4 to pass through. The inner wall of the second clearance channel 181 is provided with a second sealing ring 182 that cooperates with the center rod 4. In this way, when the center rod 4 passes through the second clearance channel 181, it can be sealed by the second sealing ring 182 to avoid water leakage. Similarly, the pilot valve seat 15 is also provided with a first clearance channel 151 for the center rod 4 to pass through.

[0079] In the above structure, the water switch operation is performed by pressing the handle 21, and the flow rate adjustment operation is performed by rotating the rotary adjustment member 3. This requires pressing and rotating different parts of the valve core, and the operation logic is not user-friendly. To this end, in this embodiment, a groove 211 is provided on the side of the handle 21, and the rotary adjustment member 3 is provided with a protrusion 312 for being placed in the groove 211, so that the handle 21 and the rotary adjustment member 3 can be linked and matched in the rotation direction. In this way, rotating the handle 21 can also drive the rotary adjustment member 3 to rotate, and all operations of the user can be realized through the handle 21.

[0080] Finally, to limit the rotation range of the rotary adjusting member 3, the valve body 1 includes a housing 17 wrapped around the outer side of the rotary adjusting member 3, and the housing 17 is provided with a first limiting boss 171 along the rotation path of the rotary adjusting member 3; the rotary adjusting member 3 is provided with a second limiting boss 32 corresponding to the first limiting boss 171; the first limiting boss 171 and the second limiting boss 32 are used to limit the rotation range of the rotary adjusting member 3. In this way, when the rotary adjusting member 3 rotates to the point where the first limiting boss 171 and the second limiting boss 32 abut, the rotary adjusting member 3 continues to rotate along the current rotation direction.

[0086] The rotary adjusting member is used to control the first sealing part to move between the second position and the third position to adjust the water outlet flow of the first flow channel 13 through the linkage control mechanism when the center rod 4 is in the second position, and the third position is between the second position and the first position; in the process of the rotary adjusting member controlling the first sealing part to move between the second position and the third position through the linkage control mechanism, the first sealing part has 1, 2, 3, 4, 5..., n positions, and the first sealing part can stay in any one of the n positions according to the control of the rotary adjusting member, and when staying in different positions, the water outlet flow of the first flow channel 13 will change, thereby realizing stepless flow adjustment; when the first sealing part is in the third position, the first sealing part seals the first flow channel 13, and the second flow channel 14 remains connected.

[0087] The above-mentioned push-switch water-rotating flow regulating valve core is provided with a second flow channel 14. During the process of rotating the flow regulating, the first flow channel 13 can be rotated to adjust the size, and the second flow channel 14 remains in a normally open fixed non-adjustable flow state, and the two water channels merge and discharge, so that the minimum flow of the product is determined by the second flow channel 14. When the first flow channel 13 is rotated to adjust the flow of the first flow channel 13 to zero, the minimum flow of the valve core is the flow of the second flow channel 14, and the flow is stable, so that the minimum flow value of the product can be more accurately controlled in a smaller flow range during mass production, thereby increasing the product flow control accuracy and stability.

[0088] To realize water switching, the first sealing part is a pilot valve, including a pilot valve seat 15 and a diaphragm 16 fixed on the pilot valve seat 15, the diaphragm 16 is provided with a pressure relief hole 161 for the center rod 4 to pass through, and a water replenishment port 162 with a diameter smaller than the pressure relief hole 161; the pilot valve and the middle seat 18 of the valve body 1 form a pressure chamber 163; the center rod 4 is provided with a first part 41 and a second part 42, and the diameter of the second part 42 is larger than the first part 41;

[0089] When the center rod 4 is in the first position, the second part 42 is located in the pressure relief hole 161 and seals the pressure relief hole 161. Water from the outside enters the pressure chamber 163 through the water replenishment port 162, causing the pressure in the pressure chamber 163 to increase. The pilot valve moves downward under the pressure in the pressure chamber 163, driving the diaphragm 16 to deform downward, thereby sealing the first flow channel 13 and shutting off the water in the first flow channel 13. When the center rod 4 is in the second position, the first part 41 is located in the pressure relief hole 161. Since the diameter of the first part 41 is relatively small, there is a gap between the first part 41 and the pressure relief hole 161, so that the pressure relief hole 161 is opened, and the water in the pressure chamber 163 flows out from the pressure relief hole 161, causing the water pressure in the pressure chamber 163 to drop, and the pressure outside the pressure chamber 163 is greater than the pressure inside the pressure chamber 163. At this time, the pilot valve moves upward under the action of the pressure outside the pressure chamber 163, driving the diaphragm 16 to deform upward, thereby releasing the seal of the first flow channel 13, and realizing the boiling of water in the first flow channel 13.

[0090] In addition, in this embodiment, the connection point between the second flow channel 14 and the water inlet 11 is the pressure relief hole 161. Since the pressure relief hole 161 is opened when the center rod 4 is in the second position, the water flow can continuously enter the pressure chamber 163 from the water replenishment port 162 and then flow out from the pressure relief hole 161 during the flow adjustment process, ensuring that the second flow channel 14 is always in an open state. When the center rod 4 is in the first position, the pressure relief hole 161 has been closed, and the second flow channel 14 is naturally closed.

[0091] To realize the water on / off operation, the center rod 4 and the pilot valve can be moved from the first position to the second position, or from the second position to the first position, and the pressing operation member 2 is required to drive the movement of the center rod 4. Specifically, the pressing operation member 2 includes a rod 21, and a boss 22 is fixedly arranged inside the rod 21; a water-opening spring 45 is arranged outside the center rod 4;

[0092] The handle bar 21 is located in a high position or a low position under the action of an external force. When the handle bar 21 is located in a low position, the boss 22 abuts against the center rod 4 to drive the center rod 4 and the pilot valve to be in a first position, and the center rod 4 squeezes the boiling water spring 45 to accumulate elastic restoring force; when the handle bar 21 is located in a high position, the boss 22 is separated from the center rod 4, and the center rod 4 and the pilot valve move to the second position driven by the restoring force of the boiling water spring 45.

[0093] The above structure can realize the operation of turning off and on the water. Then, to realize the flow adjustment operation in the state of turning on the water, it is necessary to rely on the rotating adjustment member 3 and the linkage control mechanism. In this embodiment, the linkage control mechanism is the adjustment seat 6; the function of the rotating adjustment member 3 is to rotate under the external force of the user. The rotating adjustment member 3 directly acts on the pilot valve through the adjustment seat 6 to move the pilot valve between the second position and the third position, thereby driving the diaphragm 16 to deform.

[0094] Furthermore, the adjustment seat 6 has a boss 61 extending into the pressure chamber 163; when the rotary adjustment member 3 rotates to drive the adjustment seat 6 to move, the boss 61 abuts against the pilot valve and drives the pilot valve to move between the second position and the third position to adjust the water flow rate of the first flow channel 13. When the pilot valve is located at the third position, the diaphragm 16 seals the first flow channel 13. In the process of the boss 61 driving the pilot valve to move, the distance between the diaphragm 16 and the first flow channel 13 will become smaller, and the water flow rate will also decrease accordingly.

[0095] In this embodiment, the adjusting seat 6 abuts against the adjusting spring 62, and the adjusting spring 62 accumulates elastic reset force during the movement of the pilot valve from the second position to the third position. In addition, the adjusting seat 6 extends radially outward to form a lug 63 that abuts against the lower end surface of the rotating adjusting member 3, and the lower end surface of the rotating adjusting member 3 is a slope 31 that gradually rises along the rotation direction; in this way, when the rotating adjusting member 3 rotates relative to the adjusting seat 6, the lug 63 on the adjusting seat 6 will move to different positions of the slope 31, for example, when the lug 63 moves to the highest position of the slope 31, the center rod 4 is located at the second position, and when the lug 63 moves to the lowest position of the slope 31, the center rod 4 is located at the third position. When the lug 63 moves from the highest position to the lowest position of the slope 31, an extrusion force will be generated between the slope 31 and the lug 63 to drive the adjusting seat 6 to move downward, and at this time, the adjusting seat 6 squeezes the adjusting spring 62. When the lug 63 moves from the highest position to the lowest position of the inclined surface 31 , the squeezing force between the inclined surface 31 and the lug 63 disappears, and the adjustment spring 62 releases the elastic restoring force to drive the adjustment seat 6 to move upward.

[0096] To form the pressure chamber 163, the valve body 1 further includes the middle seat 18, which defines the pressure chamber 163 with the diaphragm 16 and the pilot valve seat 15. The middle seat 18 is provided with a second clearance passage 181 for the central rod 4 to pass through; the inner wall of the second clearance passage 181 is provided with a second sealing ring 182 that cooperates with the central rod 4. In this way, when the central rod 4 passes through the clearance passage 181, it can be sealed by the second sealing ring 182 to avoid water leakage.

[0097] Similarly, the pilot valve seat 15 is also provided with a first clearance channel 151 for the center rod 4 to pass through. In order to prevent the water-boosting spring 45 from driving the center rod 4 to reset alone, causing the center rod 4 and the pilot valve to separate. In this embodiment, a slope 47 is provided on the center rod 4, and a protrusion 1511 that cooperates with the slope is provided in the first clearance channel 151 of the pilot valve seat 15; when the water-boosting spring 45 drives the center rod 4 to reset, the slope 47 will abut against the protrusion 1511, so that the center rod 4 and the pilot valve seat 15 are linked, so that the pilot valve seat 15 is also moved from the first position to the second position. In the process of adjusting the flow rate, the rotating adjusting member 3 directly acts on the pilot valve through the adjusting seat 6, driving the pilot valve seat 15 on the pilot valve to move up and down, and the protrusion 1511 on the pilot valve seat 15 cooperates with the inclined surface 47 on the center rod 4 to drive the center rod 4 to move up and down synchronously. During the movement, the pressure relief hole 161 through the second flow channel 14 is always kept open and the flow rate remains unchanged. The change in flow rate in the process of adjusting the flow rate is not caused by the up and down movement of the center rod 4. The flow change is achieved by the rotating adjusting member 3 directly acting on the pilot valve through the adjusting seat 6 to drive the pilot valve to move up and down. Another alternative method is to set a slope at the middle position of the center rod 4, and set a protrusion matching the slope at the position of the middle seat 18. In this way, when the rotating adjustment member 3 acts directly on the pilot valve through the adjustment seat 6 to drive the pilot valve to move during the flow adjustment process, the center rod 4 will not move up and down during the flow adjustment process, and it can also prevent the boiling water spring 45 from driving the center rod 4 to reset alone during the boiling water process, causing the center rod 4 and the pilot valve to separate.

[0098] In the above structure, the water on / off operation is performed by pressing the handle 21, and the flow rate adjustment operation is performed by rotating the rotary adjusting member 3. This requires pressing and rotating different parts of the valve core, and the operation logic is not user-friendly. To this end, in this embodiment, a groove 211 is provided on the side of the handle 21, and the rotary adjusting member 3 is provided with a protrusion 312 for being placed in the groove 211, so that the handle 21 and the rotary adjusting member 3 can be linked and matched in the rotation direction. In this way, rotating the handle 21 can also drive the rotary adjusting member 3 to rotate, and all operations of the user can be realized through the handle 21.

[0099] Finally, to limit the rotation range of the rotary adjusting member 3, the valve body 1 includes a housing 17 wrapped around the outer side of the rotary adjusting member 3, and the housing 17 is provided with a first limiting boss 171 along the rotation path of the rotary adjusting member 3; the rotary adjusting member 3 is provided with a second limiting boss 32 corresponding to the first limiting boss 171; the first limiting boss 171 and the second limiting boss 32 are used to limit the rotation range of the rotary adjusting member 3. In this way, when the rotary adjusting member 3 rotates to the point where the first limiting boss 171 and the second limiting boss 32 abut, the rotary adjusting member 3 continues to rotate along the current rotation direction.

[0100] Example 3

[0101] refer to Figure 12-15 In this embodiment, the second flow channel is arranged on the pilot valve seat 15 , and the diaphragm 16 is provided with a clearance opening at a position corresponding to the outlet of the second flow channel 14 .

[0102] Since the pilot valve seat 15 is provided with a first clearance channel 151 for the central rod to pass through, the second flow channel 14 can be connected to the water outlet 12 through the first clearance channel 151, and connected to the water inlet 11 through the clearance opening. To close the second flow channel 14, a sealing member 19 is provided on the inner wall of the first clearance channel 15 as the second sealing portion in this embodiment.

[0103] Correspondingly, a first part 41 and a second part 42 are provided on the center rod 4, and the diameter of the second part 42 is larger than that of the first part 41; when the center rod 4 is located at the first position, the second part 42 is located in the pressure relief hole 161 and seals the pressure relief hole 161, and the diaphragm 16 seals the first flow channel 13 under the action of the pressure in the pressure chamber, and the second part 42 cooperates with the seal 19 to close the second flow channel 14; when the center rod 4 is located at the second position, the first part 41 is located in the pressure relief hole 161 and opens the pressure relief hole 161, and the diaphragm 16 releases the seal of the first flow channel 13 under the action of the pressure outside the pressure chamber, and the second part 42 releases the cooperation with the seal 19 to open the second flow channel 14. When the center rod 4 is located at the third position, the second part 42 is located in the pressure relief hole 161 and seals the pressure relief hole 161, and the diaphragm 16 seals the first flow channel 13 under the pressure in the pressure chamber, and at this time the second part 42 is released from the seal 19 to open the second flow channel 14, forming a state of minimum water flow.
