[0027] Embodiment one

[0028] Please refer to Figure 2 The utility model introduces a kind of bladder urethral operating mirror of flush water multi-gear adjustment, it includes operating mirror main body structure 1, two valves 8, two gear adjuster 2, it can also include scale 41 and color area 42.Two valves 8 are respectively installed at the water inlet and water outlet of operating mirror main body structure 1, for respectively controlling the water inlet and water outlet of operating mirror main body structure 1, and each valve 8 is equipped with the handle 81 of controlling the flow or cut-off of corresponding valve 8.Two gear adjuster 2 are respectively used to rotate corresponding handle 81 and drive valve core to rotate, and through hole is opened on spherical valve core, and water flows from through hole.From the realization operating mirror main body structure 1's water inlet multi-gear adjustment and water outlet multi-gear adjustment.

[0029] In the above embodiment, flush water first flows into water inlet pipeline through spherical valve 8, then flush water enters the internal pipeline of operating mirror main body structure 1 and flows into bladder, then flush water refluxes from multiple small holes on the outer wall of internal pipeline, and after flowing out from internal pipeline to water outlet, it flows out through spherical valve 8, and in this process, the rotation angle of spherical valve core in spherical valve 8 can be changed by adjusting the rotation opening and closing degree of gear adjuster 2 of spherical valve 8, to control the control of flush water flow.

[0030] In combination Figure 4 And Figure 5Each gear adjuster 2 comprises a rotating shaft 5, a handle 7, a rotating disc 6, a locking structure 3, and an adjuster housing 4. One end of the rotating shaft 5 is coaxially connected with the handle 81. The handle 7 is fixed on the other end of the rotating shaft 5 for rotating the rotating shaft 5. The rotating disc 6 is sleeved on the rotating shaft 5 and is coaxially fixed with the rotating shaft 5. A plurality of notches representing a plurality of gears are formed on the circumferential surface of the rotating disc 6, and the flanges between the notches form an arc-shaped gear 61 on the rotating disc 6. The locking structure 3 comprises a torsion spring 31, one end of the torsion spring 31 is provided with a protrusion 32 engaged with the arc-shaped gear 61, and the other end of the torsion spring 31 is fixed on the operating mirror main body structure 1. The rotating shaft 5 is driven to rotate by rotating the handle 7, and the rotating disc 6 is rotated to drive the protrusion 32 to reciprocally engage with the arc-shaped gears 61 for multi-gear adjustment.

[0031] In the above embodiment, the rotating shaft 5 is driven to rotate by rotating the handle 7, the rotating shaft 5 drives the rotating disc 6 to rotate and the arc-shaped gears 61 to rotate, the arc surface of the arc-shaped gears 61 lifts the protrusion 32, the arc-shaped gears 61 rotate, and the protrusion 32 is always attached to the outer contour of the arc-shaped gears 61 under the action of the torsion spring 31. When the arc-shaped gears 61 rotate to the next gear, the bottom of the protrusion 32 is engaged with the groove of the next arc-shaped gear 61, thereby realizing gear switching operation and self-locking of the gear, so that the rotation angle of the handle 81 can be accurately controlled, thereby solving the technical problem that the existing operating mirror cannot timely and accurately control the water inlet and outlet flow of the flushing water.

[0032] The locking structure 3 can also be a circular rod fixed on the operating mirror main body structure 1, one end of the torsion spring 31 is fixed on the operating mirror main body structure 1, the torsion spring 31 is sleeved on the outer wall of the circular rod, the other end of the torsion spring 31 is fixed on the outer wall of the circular rod, and one end of the torsion spring 31 is fixed with the protrusion 32. The protrusion 32 is lifted and lowered by the torsion spring 31 for engaging the protrusion 32 with the arc-shaped gears 61.

[0033] In the above embodiment, the torsion spring 31 is sleeved on the outer wall of the circular rod, which can improve the stability of the torsion spring 31 during deformation, thereby reducing the swing amplitude of the torsion spring 31 during deformation.

[0034] The locking structure 3 can also be a rotating seat fixed on the operating mirror main body structure 1, a circular rod is rotatably connected to the rotating seat, the torsion spring 31 is sleeved on the outer wall of the circular rod, one end of the torsion spring 31 is fixed on the outer wall of the circular rod, the other end of the torsion spring 31 is fixed on the operating mirror main body structure 1, and the outer wall of the circular rod is fixed with the protrusion 32.

[0035] In the above embodiment, the rotation of the circular rod realizes the lifting and lowering of the protrusion 32, so that the torsion spring 31 does not directly contact the protrusion 32, but drives the circular rod to rotate. Since the circular rod is limited by the rotating seat, the deformation of the torsion spring 31 will not affect the protrusion 32 to make it shake, and the stability of the protrusion 32 during movement can be well improved.

[0036] The arc-shaped teeth 61 can be evenly distributed along the circumferential end surface of the rotating disc 6. The same groove spacing between adjacent arc-shaped teeth 61 can make the angle consistent when the protrusion 32 is clamped, thereby improving the accuracy of the gear.

[0037] The arc-shaped teeth 61 can also be distributed along a quarter circumferential ring surface of the rotating disc 6, and the extended lines of the inner sides of the two edge profiles of the remaining three-quarters of the ring surface pass through the center of the rotating disc 6. The groove surfaces on both sides of the arc-shaped teeth 61 can block the protrusion 32 when in contact with the protrusion 32, thereby controlling the angle of rotation of the rotating disc 6 within a right angle range.

[0038] In the above embodiment, the rotating disc 6 can be divided into four equal areas, one of which has a plurality of teeth arranged on the arc side, and the inner angle of the arc-shaped teeth is obtuse, and the torsional spring 31 has a tendency to rotate. When the rotating disc 6 is rotated, the rotating disc 6 pushes the protrusion 32 upward, and after the protrusion 32 is pushed upward, it descends in the next arc-shaped tooth. The protrusion 32 can move back and forth in the plurality of tooth grooves by virtue of the rotation of the circular rod and the elastic deformation of the torsional spring 31, and can be self-locked after moving without external force, thereby realizing step-by-step rotation, so that the angle of rotation of the rotating disc 6 can be accurately controlled. The flow rate of the water flow is quantified into the rotation angle of the handle, and the rotation angle is hierarchical, achieving the effect of precise control, solving the technical problem that the existing operation mirror cannot timely and accurately control the water inflow and outflow of the flushing water. The protrusion can be triangular or trapezoidal, as long as it can move in multiple tooth grooves after elastic deformation.

[0039] The regulator shell 4 can be provided outside the gear adjuster 2, and the regulator shell 4 is fixed on the outer wall of the valve 8 by welding. The handle 7 is located outside the regulator shell 4, and a plurality of scales 41 are arranged on the regulator shell 4. The projection of the handle 7 on the vertical direction of the outer wall of the regulator shell 4 is aligned with one of the plurality of scales 41. The scale 41 is long and is evenly distributed along the circumferential direction of the rotating disc 6.

[0040] In the above embodiment, rotating the handle 7 can make the outer contour of the handle 7 outside one of the plurality of scales 41. The angle of rotation of the spherical valve 8 can be determined by observing the position of the handle 7 aligned with the scale 41, and the different angles are quantified hierarchically (for example, the flow rate is 1 at the first angle, and the flow rate is 2 at the second angle), so that the flow rate of the current position can be obtained, the precise control and reading of the flow rate can be realized, and the reading efficiency can be improved. And the accuracy is changed according to the accuracy of the scale 41 and the number of teeth of the rotating disc 6. The regulator shell 4 can also be detachably mounted on the outer wall of the pipeline 11, for example, buckling.

[0042] Please refer to Figures 3 to 6 The difference from the first embodiment is that

[0043] The color zones 42 can be arranged on the outer wall of the regulator housing 4, and the projection of the handle 7 in the vertical direction of the outer wall of the regulator housing 4 is aligned with one of the color zones 42.

[0044] The color zones 42 are fan-shaped and are evenly distributed along the circumferential direction of the rotary disc 6.

[0045] In the above embodiment, the level to which the handle 7 is located is determined by observing the position of the handle 7 and the normal projection of the color zones 42, and the advantage is that the color zones 42 can be divided into different color zones, and the flow speed level to which the handle 7 belongs can be observed more obviously than the scale.

[0046] The technical features of the above embodiments can be combined in any manner, and for the sake of brevity, not all possible combinations of the technical features in the above embodiments are described, but as long as the combinations of the technical features do not contradict, they should be considered as within the scope of the present disclosure.
