Referring to fig. 1 and 2, fig. 1 and 2 show schematic structural diagrams 1 and 2 of an embodiment 1 of a flow valve provided by the present invention, including a flow valve body, on which a water inlet end and a water outlet end are provided, a water inlet cavity 11 and a water outlet cavity 12 are correspondingly provided in the body, and the water inlet cavity 11 and the water outlet cavity 12 are communicated through a water channel 13, and further include a cup holder 20, an adjusting holder 30, a limiting holder 31, a rotating holder 40, a torsion spring 41, a pressing reset device, a handle cover 71 and a handle holder 72.
As shown in fig. 9, a cavity wall is arranged between the water inlet cavity 11 and the water outlet cavity 12, a water passage 13 is formed at the upper end of the cavity wall, and a cup holder 20 is positioned above the cavity wall.
The cup holder 20 is deformed or moved in an axial direction to block or separate from the water passing channel 13. In one embodiment, the two ends of the cup holder 20 are fixed on the body, the middle area can be elastically deformed, the distance between the cup holder and the upper end of the cavity wall is adjusted through deformation, the water passage 13 is blocked when the cup holder abuts against the upper end of the cavity wall, and the water passage 13 is unobstructed when the cup holder is far away from the upper end of the cavity wall, and the specific structure of the cup holder can be a membrane. In another embodiment, the cup holder 20 comprises a plastic member and a rubber member, the rubber member being fixedly connected to the plastic member to seal the water passage 13 when the cup holder 20 abuts against the upper end of the cavity wall, the plastic member being movable in the axial direction to a small extent, by which action the water passage 13 is blocked or kept away.
The adjustment seat 30 is located above the cup seat 20 and moves in an axial direction to abut against or disengage from the cup seat 20. The limiting seat 31 is located below the adjusting seat 30, between the adjusting seat 30 and the cup seat 20, and is fixedly connected with the flow valve body, and meanwhile, the adjusting seat 30 is limited by the structure of the limiting seat 31, and can only move in a small range in the axial direction and cannot rotate. The wall surface of the adjusting seat 30 facing the cup seat 20 is provided with a propping rod 33, and the propping rod 33 penetrates through the limiting seat 31 to prop against the cup seat 20. A sealing ring is connected to the abutment rod 33 to prevent water flow from the pressure chamber 51 into the valve body.
The rotating seat 40 is located above the adjusting seat 30, and can rotate along the circumferential direction and is in inclined fit with the adjusting seat 30 in the axial direction. As shown in fig. 5 and 6, an inclined slope is provided on the lower end surface of the rotating seat 40, an inclined groove is provided on the upper end surface of the adjusting seat 30, the inclined directions of the rotating seat 40 and the inclined surface on the adjusting seat 30 are all set along the circumferential direction, the inclined surfaces on the rotating seat 40 and the adjusting seat 30 are matched, the rotating seat 40 can be inserted into the adjusting seat 30, at this time, the rotating seat and the inclined surfaces are propped against each other, and since the adjusting seat 30 can only move in the axial direction, when the rotating seat 40 rotates from the deepest part of the chute on the adjusting seat 30 to the shallowest part of the chute, the adjusting seat 30 is propped and pushed to move downwards, and the propping rod 33 moves downwards and pushes the leather cup seat 20 to move downwards.
As can be seen from the above structure, the flow valve provided by the invention has the function of adjusting the flow of water. By rotating the rotating seat 40, the adjusting seat 30 moves downwards, so as to push the leather cup seat 20 to move downwards, thereby changing the superposition area of the leather cup seat 20 and the water passing channel 13, namely changing the water passing area of the water passing channel 13, and achieving the purpose of adjusting the flow.
Meanwhile, the flow regulating function not only can regulate the flow down, but also can regulate the flow up, namely, the flow is regulated by increasing the water passing area of the water channel 13. The structure of the cup seat comprises a first spring 32, one end of the first spring 32 is propped against a limit seat 31, the other end is propped against an adjusting seat 30, when a rotating seat 40 rotates clockwise, namely, the flow is reduced, the adjusting seat 30 moves downwards, the first spring 32 stores potential energy, and when the rotating seat 40 rotates anticlockwise, the first spring 32 pushes the adjusting seat 30 to move upwards, so that the cup seat 20 is driven by water pressure to rise, and the flow is increased.
When the flow is regulated to a required state by rotating the rotating seat, the relative positions of the matching surfaces of the regulating seat 30 and the rotating seat 40 are fixed by friction force, specifically, the chute surface of the regulating seat 30 and the slope surface of the rotating seat 40 can be made of materials which can provide higher friction force, such as rubber materials, or salient points are arranged between the matching surfaces to increase the friction force, and the friction force can be controlled by controlling the density of the salient points. In addition, the first spring 32 pushes the adjusting seat 30 upwards, so as to provide corresponding pressure, so that a certain friction force exists between the matching surfaces of the adjusting seat 30 and the rotating seat 40 all the time, and displacement of the rotating seat 40 is avoided.
The flow valve provided by the invention further comprises a pressing reset device, the structure of which is similar to that of a common ball-point pen refill capable of being pressed, and specifically comprises a sleeve 61, an upper ratchet wheel 62, a lower ratchet wheel 63, a second spring 64 and a center rod 65. The sleeve 61 is fixedly connected to the body, a low-position positioning point and a high-position positioning point are arranged on the inner side wall of the sleeve 61, as shown in fig. 8, in this embodiment, three sets of positioning structures are adaptively arranged according to the structures of the upper ratchet wheel 62 and the lower ratchet wheel 63, each set of positioning structure comprises a low-position positioning point formed by an inclined plane and a high-position positioning point formed by a groove, a sliding groove is further arranged on the inner side wall of the sleeve 61, and a sliding block matched with the sliding groove is arranged on the upper ratchet wheel 62, so that the upper ratchet wheel 62 can only move in the axial direction.
As shown in fig. 7, the upper ratchet 62 is slidably connected to the sleeve 61, and is provided with a first ratchet at its lower end face, and the lower ratchet 63 is slidably connected to the sleeve, and is provided with a second ratchet matching the first ratchet at its upper end face, and an abutment for abutting the low-position positioning point and the high-position positioning point. The upper ratchet 62 descends after being pressed, the first ratchet is inclined against the second ratchet, the circumferential rotation of the upper ratchet 62 is restricted because the upper ratchet 62 can move only in the axial direction, and the lower ratchet 63 can move and rotate both in the axial direction and in the circumferential direction, and when the first ratchet is inclined against the second ratchet, the lower ratchet 63 performs both the rotational movement and the downward movement. If the abutting portion of the lower ratchet 63 is originally abutted against the low positioning point on the inner side wall of the sleeve 61, the lower ratchet 63 can be separated from the low positioning point through downward movement, and simultaneously slides towards the high positioning point under the action of the inclined plane between the low positioning point and the high positioning point of the sleeve 61. The two ends of the second spring 64 respectively prop against the central rod 65 and the body, the central rod 65 provides upward pressure to the lower ratchet 63, and the lower ratchet 63 enters a high positioning point under the action of the pressure to complete one-time position switching and positioning. If the abutting portion of the lower ratchet 63 is originally abutted against the high positioning point on the inner side wall of the sleeve 61, the lower ratchet 63 can be separated from the high positioning point through downward movement, and simultaneously slides towards the high positioning point under the action of the inclined surface of the low positioning point of the sleeve 61 and keeps abutting and positioning under the action of the second spring 64.
The central rod 65 includes a receiving chamber and an elongated rod positioned below for plugging or communicating the relief aperture 52. The accommodating chamber comprises a third spring 67 and a connecting seat 66, the outer side of the connecting seat 66 is cylindrical and can slide in the accommodating chamber of the central rod 65, one end of the third spring 67 abuts against the inner bottom surface of the accommodating chamber of the central rod 65, the other end abuts against the lower end surface of the connecting seat 66, and the lower ratchet 63 is provided with a bulge in the center of the lower end surface, and the bulge abuts against the upper end surface of the connecting seat 66; the upper end surface of the receiving chamber of the central rod 65 extends in the horizontal direction towards the outer periphery with a blocking surface, against which the second spring 64 abuts in this embodiment the central rod 65. When the lower ratchet wheel 63 is positioned at a low positioning point, the lower ratchet wheel 63 is always propped against the upper end face of the connecting seat 66, and is propped against the central rod through the third spring 67, so that the central rod 65 always keeps downward positive pressure under the action of the third spring 67, and the sealing performance of the pressure release hole 52 is ensured under the water closing state of the flow valve, thereby avoiding the water leakage.
In the embodiment 1 provided by the invention, the lower end of the long rod on the central rod 65 penetrates through the pressure release hole 52, and meanwhile, a water passing hole is reserved between the central rod 65 and the pressure release hole 52, so that water flows through the water passing hole, and the water pressure balance of the pressure bearing cavity 51 and the water outlet cavity 12 is kept. A first sealing ring 652 is arranged at the position of the central rod 65 positioned on the cup holder 20, a second sealing ring 653 is arranged at the position of the central rod 65 positioned below the cup holder 20, the first sealing ring 652 pushes the cup holder 20 to move downwards when the central rod 65 moves downwards, and the second sealing ring 653 pushes the cup holder to move upwards when the central rod 65 moves upwards. Specifically, in the boiled water state, after the reset device is pressed down, the upper ratchet wheel 62 moves down to drive the lower ratchet wheel 63 to move from the high positioning point to the low positioning point, in the process, the center rod 65 moves down, so that the first sealing ring 652 abuts against the cup seat 20 and seals the pressure release hole 52, water flows into the pressure-bearing cavity 51 from the water inlet hole 53, and the pressure of the pressure-bearing cavity 51 increases to push the cup seat 20 to move down or deform so as to block the water passage 13, thereby achieving the purpose of closing water. In the water-off state, after the pressing reset device is pressed down, the upper ratchet wheel 62 moves down to drive the lower ratchet wheel 63 to move from the low positioning point to the high positioning point, in the process, the central rod 65 moves up, so that the first sealing ring 652 is separated from the cup seat 20 and the pressure release hole 52 is restored to be communicated, the pressure release hole 52 discharges water, and when the central rod 65 moves up to a certain position, the second sealing ring 653 abuts against the cup seat 20, and the cup seat 20 is pulled to move up or deform, so that the water channel 13 is restored to be communicated. The second sealing ring 653 can provide an upward auxiliary force for the cup 20, so as to prevent the cup 20 from rising when water pressure is intersected, and the flow valve from boiling water.
In the embodiment 2 provided by the invention, as shown in fig. 3 and 4, the lower end of the central rod 65 is fixedly connected with a rubber block 651, and the rubber block 651 moves along with the central rod 65 to block or be far away from the pressure release hole 52 so as to achieve the purpose of switching water.

As shown in fig. 5 and 6, between the rotating seat 40 and the adjusting seat 30, a torsion spring 41 is provided, the torsion spring 41 is a spring curled around the rotating seat 40, one end of which is transversely inserted into the rotating seat 40 to be fixedly connected therewith, and the other end of which is vertically inserted into the adjusting seat 30 to be fixedly connected therewith, and when the flow valve is positioned at the maximum flow rate, i.e., when the rotating seat 40 is fully inserted with the adjusting seat 30, the torsion spring 41 is positioned at the initial position, in which it is not stressed. When the flow valve is in a boiled water state, the rotating seat 40 rotates to enable the torsion spring 41 to be separated from the initial position, the torsion spring 41 is stressed due to the fact that the adjusting seat 30 cannot rotate, and a reset steering force is applied to the rotating seat 40, and due to the fact that friction force exists on the matching surface between the rotating seat 40 and the adjusting seat 30, the friction force is formed by upward pressure applied to the adjusting seat 30 and mainly comprises the elastic force of the first spring 32, the friction force of the sealing ring between the adjusting seat 30 and the limiting seat 31, and the reaction force when the propping rod 33 of the adjusting seat 30 props against the leather cup seat 20, when the friction force between the matching surfaces is larger than the steering force provided by the torsion spring 41, the rotating seat 40 is not affected by the torsion spring 41, and the position is kept fixed under the friction force. When the pressing reset device is pressed down, the central rod 65 abuts against the cup holder 20 and drives the cup holder 20 to move downwards or deform, so that the abutting rod 33 of the adjusting seat 30 is separated from the cup holder 20, at this time, the pressure between the matching surfaces of the adjusting seat 30 and the rotating seat 40 is reduced, the friction force is reduced, the torsion force of the torsion spring 41 is set to be suitable, the torsion force of the torsion spring 41 is made to be larger than the friction force between the matching surfaces of the adjusting seat 30 and the rotating seat 40 when the cup holder 20 is separated from the adjusting seat 30, and therefore the torsion spring 41 acts to reset the rotating seat 40 to the maximum flow position, and the adjusting seat 30 is reset under the action of the first spring 32. Through the structure, the rotating seat 40 and the adjusting seat 30 can be reset to the maximum flow when water is closed, the flow does not need to be adjusted to the maximum flow when boiled water is used next time, and the situation that the handle cover 71 needs to be rotated to adjust the flow when boiled water is used next time due to the fact that the flow is reduced when the water is used last time is avoided.
When the flow valve is specifically used, the flow valve provided by the invention comprises a water switching function, a flow regulating function and a water closing and resetting function, the water switching function is realized by pressing the resetting device, the handle cover 71 is pressed down, the upper ratchet wheel 62 drives the lower ratchet wheel 63 to rotate and be fixed at a low positioning point or a high positioning point, the central rod 65 is driven to move up and down so as to enable the leather cup seat 20 to block or open the water passing channel 13, when the water passing channel 13 is blocked, the flow valve is closed, and when the water passing channel 13 is opened, the flow valve is boiled water. The flow regulating function is carried out under the boiled water state of the flow valve, the handle cover 71 is rotated to drive the handle seat 72 to rotate, the rotating seat 40 is driven to rotate through the meshing teeth, the regulating seat 30 is matched with the inclined surface of the rotating seat 40 to enable the regulating seat 30 to move downwards, the propping rod 33 is propped against the leather cup seat 20, the distance between the leather cup seat 20 and the cavity wall is changed, and the water passing area of the water channel 13 is regulated, so that the purpose of regulating flow is achieved. The water closing reset function is performed under the boiled water state of the flow valve, at the moment, the propping rod 33 is propped against the leather cup seat 20, after the handle cover 71 is pressed down, the leather cup seat 20 is pushed to move downwards to close water, the propping rod 33 is separated from the leather cup seat 20, the torsion force of the torsion spring 41 is larger than the friction force between the matching surfaces of the adjusting seat 30 and the rotating seat 40, thereby pushing the rotating seat 40 to reset to the maximum flow position, and the adjusting seat 30 is reset under the action of the first spring 32, so that the water closing reset function is achieved.
According to the flow valve provided by the invention, the rotation of the rotating seat 40 is converted into the axial movement of the adjusting seat 30 through the inclined plane matching, the adjusting seat 30 is propped against the leather cup seat 20 when moving, the leather cup seat 20 moves or deforms in the axial direction relative to the water passing channel 13 so as to change the water passing area of the water passing channel 13, so that the water passing flow of the flow valve is adjusted, the flow valve is simple in structure and easy to maintain, the flow valve can bear large pressure and is not easy to damage, meanwhile, the torsion spring 41 is arranged to connect the adjusting seat 30 and the rotating seat 40, and when the adjusting seat 30 is separated from the leather cup seat 20, the friction force between the matching surfaces of the adjusting seat 30 and the rotating seat 40 is smaller than the elastic force of the torsion spring 41, and the torsion spring 41 is utilized to push the rotating seat 40 to reset to the maximum flow, so that the problem that the rotating seat 40 cannot be reset automatically is solved.
