It is hereby stated that the directional terms such as up, down, left, right, front, back, inside, outside, etc. that appear or will appear in the text of the present invention are only based on the accompanying drawings of the present invention, and are not specific limitations of the present invention.

[0034] See also Figure 1 and Figure 2 The embodiment of the present invention discloses a full-drain and half-drain water replenishment control device, including a switching mechanism 1, an adjusting mechanism 2 and a pipeline mechanism 3. The switching mechanism 1 is used to switch the water replenishment channel of the full-drain pipeline and the water replenishment channel of the half-drain pipeline.

The switching mechanism 1 and the adjusting mechanism 2 are both integrated and built into the installation cavity 411, thereby improving the space utilization rate of the drain valve 4 and reducing the occupied space of the full-drain and half-drain water replenishment control device.

[0035] Specifically, the switching mechanism 1 includes a rotating switching member 11, and the pipeline mechanism 3 includes a water replenishing water inlet pipe 31 for replenishing water to the overflow pipe 42. The rotating switching member 11 is provided with an inner cavity for passing water. The rotating switching member 11 is connected with the water replenishing water inlet pipe 31. When replenishing water, water can enter the inner cavity of the rotating switching member 11 from the water replenishing water inlet pipe 31. The pipeline mechanism 3 also includes a full discharge water pipe 32 and a half discharge water pipe 33 connected with the overflow pipe 42. The full row button 43 and the half row button 44 can drive the rotating switching member 11 to generate rotational motions in opposite directions respectively. When rotating, the rotating switching member 11 can be connected with the full discharge water pipe 32 or the half discharge water pipe 33 alone, so that the water entering the rotating switching member 11 from the water replenishing water inlet pipe 31 can be passed to the full discharge water pipe 32 or the half discharge water pipe 33 alone, and then replenish water toward the overflow pipe 42. In order to adjust the flow of the full discharge pipe 32 or the half discharge pipe 33, the regulating mechanism 2 includes a full row regulating knob 21 and a half row regulating knob 22 for adjusting the water replenishment flow.

One end of the regulating mechanism 2 is connected to the full discharge pipe 32 and the half discharge pipe 33 respectively, and the other end is connected to the overflow pipe 42.

[0036] The beneficial effects of the embodiments of the present invention are as follows:

[0037] The full-row and half-row water replenishment control device of the embodiment of the present invention is provided with a button seat 41, a switching mechanism 1 and an adjusting mechanism 2. The switching mechanism 1 is used to switch the full-row or half-row water replenishment channel. The adjusting mechanism 2 can adjust the flow rate of water replenishment. The button seat 41 is provided with a mounting cavity 411. The switching mechanism 1 and the adjusting mechanism 2 are both integrated and built into the mounting cavity 411, which can greatly improve the space utilization rate of the drain valve 4, thereby saving space and improving the adaptability of the drain valve 4 to the water tank size. In addition, the adjusting mechanism 2 includes a full-row adjusting knob 21 and a half-row adjusting knob 22 for adjusting the water replenishment flow rate. The full-row adjusting knob 21 and the half-row adjusting knob 22 are both exposed on the surface of the button seat 41. When adjusting the flow rate, the adjustment can be achieved without removing the drain valve 4, which is simple and convenient to use.

[0038] The shell of the drain valve 4 is cylindrical. In order to allow the switching mechanism 1 and the adjusting mechanism 2 to be fully installed in the drain valve 4, the installation cavity 411 is annular, the full row of buttons 43 and the half row of buttons 44 are arranged in the button seat 41, and the installation cavity 411 surrounds the periphery of the full row of buttons 43 and the half row of buttons 44. The full discharge water pipe 32 and the half discharge water pipe 33 are both arc-shaped and respectively built into the two sides of the installation cavity 411, and the switching mechanism 1 and the adjusting mechanism 2 are built into the other two sides of the installation cavity 411, so as to maximize the switching mechanism 1, the adjusting mechanism 2, the full row of buttons 43, the half row of buttons 44, the full discharge water pipe 32 and the half discharge water pipe 33 are built into a small circular space, with a compact structure and space saving. The full-drain water pipe 32 and the half-drain water pipe 33 are connected to both sides of the rotating switching member 11, and the full-row buttons 43 and the half-row buttons 44 are located on both sides of the rotating switching member 11. The positions of the full-drain water pipe 32 and the half-drain water pipe 33 correspond to the positions of the full-row buttons 43 and the half-row buttons 44, respectively.

[0039] Referring to FIG. 3 , the switching mechanism 1 further comprises a water inlet three-way chamber 12, the rotating switching member 11 is hinged in the water inlet three-way chamber 12 via a hinge shaft 13, so the rotating switching member 11 can rotate in the water inlet three-way chamber 12, the water replenishment inlet pipe 31 is connected to the water inlet three-way chamber 12, the full discharge water pipe 32 and the half discharge water pipe 33 are symmetrically arranged on both sides of the water replenishment inlet pipe 31 and are connected to the water inlet three-way chamber 12, and the rotating switching member 11 can rotate counterclockwise or clockwise around the hinge shaft 13. In order to realize the switching of the water inlet channels of the full-drain water pipe 32 and the half-drain water pipe 33, the interior of the rotating switching member 11 is provided with a full-drain water hole 111 and a half-drain water hole 113 which are interconnected in sequence. The full-drain water hole 111 and the half-drain water hole 113 are interconnected through a cavity. A water outlet baffle 112 is provided on the bottom side of the rotating switching member 11. The rotating switching member 11 can rotate in the vertical direction, thereby changing the positions of the full-drain water hole 111, the water outlet baffle 112 and the half-drain water hole 113 in the water inlet three-way cavity 12. Specifically, when the rotating switching member 11 rotates in one direction, in the present embodiment, when the rotating switching member 11 rotates counterclockwise, the full-drain water hole 111 will be aligned with the full-discharge water pipe 32, so that the full-drain water hole 111 can be connected to the full-discharge water pipe 32, and at this time, the half-drain water hole 113 will move to the water outlet of the water replenishment inlet pipe 31, so that water can enter the half-drain water hole 113 from the water replenishment inlet pipe 31, and then enter the full-drain water hole 111 through the cavity, and finally be discharged from the full-discharge water pipe 32. In addition, the water outlet baffle 112 will move to the water inlet of the half-discharge water pipe 33 and block the half-discharge water pipe 33, so that water can only flow into the full-discharge water pipe 32. When the rotating switching member 11 rotates in the other direction, in the present embodiment, when the rotating switching member 11 rotates clockwise, the full-drain water hole 111 will be aligned with the water replenishment inlet pipe 31, so that the full-drain water hole 111 can be connected with the water replenishment inlet pipe 31, and at this time, the half-drain water hole 113 will move to the water inlet of the half-drain water pipe 33, so that water can enter the full-drain water hole 111 from the water replenishment inlet pipe 31, and then enter the half-drain water hole 113 through the cavity, and finally be discharged from the half-drain water pipe 33, and accordingly, the water outlet baffle 112 will move to the water inlet of the full-drain water pipe 32 and block the full-drain water pipe 32, so that water can only flow into the half-drain water pipe 33.

[0040] The rotating switching member 11 can be linked with the full-row buttons 43 or the half-row buttons 44. Specifically, the switching mechanism 1 includes a full-row driving arm 14 and a half-row driving arm 15 fixed on both sides of the hinge shaft 13, and the full-row driving arm 14 and the half-row driving arm 15 protrude toward the direction where the full-row buttons 43 and the half-row buttons 44 are located, respectively. The full-row driving arm 14 and the half-row driving arm 15 are respectively located below the full-row buttons 43 and the half-row buttons 44. By reasonably arranging the full-row buttons 43 and the half-row buttons 44 to be linked with the full-row driving arm 14 and the half-row driving arm 15, the switching mechanism 11 can be linked with the full-row buttons 43 or the half-row buttons 44. The distance between the arms 15 enables the full-row buttons 43 and the half-row buttons 44 to touch the full-row drive arms 14 and the half-row drive arms 15 respectively when moving downward. Since the full-row drive arms 14 and the half-row drive arms 15 are arranged on both sides of the hinge shaft 13 and can rotate around the hinge shaft 13, the full-row buttons 43 and the half-row buttons 44 can respectively drive the full-row drive arms 14 and the half-row drive arms 15 to rotate around the hinge shaft 13 when moving downward. When the user presses the full-row button 43, the full-row button 43 can push the full-row drive arm 14 downward to rotate around the hinge shaft 13, so that the full-row water hole 111 can be connected to the full-discharge water pipe 32, while the half-row water hole 113 is isolated from the half-discharge water pipe 33, and water enters the full-discharge water pipe 32 from the water replenishment inlet pipe 31; when the user presses the half-row button 44, the half-row button 44 can push the half-row drive arm 15 downward to rotate around the hinge shaft 13, so that the half-row water hole 113 can be connected to the half-discharge water pipe 33, while the full-row water hole 111 is isolated from the full-discharge water pipe 32, and water enters the half-discharge water pipe 33 from the water replenishment inlet pipe 31. Since the rotary switching member 11 rotates in the vertical direction around the hinge shaft 13, the driving force for driving the rotary switching member 11 to rotate is very small, and will not affect the driving of the full-row buttons 43 and the half-row buttons 44, thereby making the driving force of the full-row buttons 43 and the half-row buttons 44 smaller and having a better operating feel.

[0041] In order to limit the rotation angle range of the rotation switching member 11, a rotation limiting protrusion 131 is fixed on the hinge shaft 13, and a rotation limiting groove 114 is provided on the rotation switching member 11. The rotation limiting protrusion 131 protrudes from the side wall of the hinge shaft 13, and the rotation limiting groove 114 is recessed in the inner wall of the rotation switching member 11. The rotation limiting protrusion 131 can be inserted into the rotation limiting groove 114 and can produce relative sliding with the rotation limiting groove 114. The two sides of the groove body of the rotation limiting groove 114 can respectively abut against the two sides of the rotation limiting protrusion 131, thereby controlling the limit angle of the rotation switching member 11 when rotating counterclockwise or clockwise. Therefore, the rotation limiting groove 114 can be used to limit the rotation angle range of the rotation switching member 11 to ensure the normal operation of the rotation switching member 11.

[0042] See also Figure 4 and Figure 5 In order to achieve flow regulation, the regulating mechanism 2 also includes a full-row flow hole 211 and a half-row flow hole 221, the full-row flow hole 211 and the half-row flow hole 221 are respectively arranged at the lower part of the full-row regulating knob 21 and the half-row regulating knob 22, the full-row flow hole 211 and the half-row flow hole 221 are respectively connected to the full discharge water pipe 32 and the half-discharge water pipe 33, when the water is flowing, the full-row regulating knob 21 and the half-row regulating knob 22 can respectively control the full-row flow hole 211 and the full-discharge water pipe 32 by rotating. The flow cross-sectional area and the flow cross-sectional area between the half-row flow holes 221 and the half-row water discharge pipe 33. When a larger flow rate is needed, the user can increase the flow cross-sectional area of ​​the full-row flow holes 211 or the half-row flow holes 221 by rotating the full-row adjusting knob 21 or the half-row adjusting knob 22, thereby increasing the water replenishment flow rate. When the flow rate needs to be reduced, the user can reduce the flow cross-sectional area of ​​the full-row flow holes 211 or the half-row flow holes 221 by rotating the full-row adjusting knob 21 or the half-row adjusting knob 22, thereby reducing the water replenishment flow rate.

[0043] See also Figure 6In order to achieve a better adjustment effect and facilitate use, the upper surface of the full-row adjustment knob 21 is provided with a full-row gear scale 212 and a full-row adjustment groove 213, and the upper surface of the half-row adjustment knob 22 is provided with a half-row gear scale 222 and a half-row adjustment groove 223. The full-row gear scale 212 and the half-row gear scale 222 are circumferentially arranged on the upper surfaces of the full-row adjustment knob 21 and the half-row adjustment knob 22, and the full-row adjustment groove 213 and the half-row adjustment groove 223 are respectively arranged at the surface centers of the full-row adjustment knob 21 and the half-row adjustment knob 22. The row adjustment groove 213 and the half-row adjustment groove 223 are used to adjust the flow cross-sectional area between the full-row flow holes 111 and the half-row flow holes 113 and the full-row water pipe 32 and the half-row water pipe 33 respectively. When the flow rate needs to be adjusted, it is only necessary to use a screwdriver or other tools to rotate the full-row adjustment knob 21 or the half-row adjustment knob 22 on the full-row adjustment groove 213 and the half-row adjustment groove 223 to complete the adjustment operation. When adjusting, you can also refer to the full-row gear position scale 212 and the half-row gear position scale 222 to rotate to make the adjustment more precise.

[0044] The full-row and half-row water replenishment control device also includes an installation cover 45, which can be detachably fixed to the top of the button seat 41, and a gear marking line 451 is provided on the installation cover 45. The positions of the gear marking line 451 correspond to the positions of the full-row gear scale 212 and the half-row gear scale 222 respectively, and the gear marking line 451 can point to the full-row gear scale 212 and the half-row gear scale 222, so as to facilitate adjustment using the full-row gear scale 212 and the half-row gear scale 222.

[0045] The pipeline mechanism 3 further includes a water replenishment outlet head 34 and a water replenishment outlet pipe 35. The bottom of the water replenishment outlet head 34 is respectively connected to the full-drain water hole 111 and the half-drain water hole 113. The water in the full-drain water pipe 32 or the half-drain water pipe 33 can enter the water replenishment outlet head 34 through the full-drain water hole 111 or the half-drain water hole 113, and enter the overflow pipe 42 from the water replenishment outlet pipe 35 for water replenishment. The top of the water replenishment outlet head 34 protrudes from the installation cover 45, and the water replenishment outlet pipe 35 is connected to the top of the water replenishment outlet head 34. Therefore, during installation and maintenance, the water replenishment outlet pipe 35 can be easily installed and removed. In order to prevent the water replenishment outlet pipe 35 from rotating and deviating on the water replenishment outlet head 34, causing the pipeline to be messy and affecting the use, a water outlet limiting boss 341 is provided on the top of the water replenishment outlet head 34. The water outlet limiting boss 341 protrudes from the top of the water replenishment outlet head 34, and the water replenishment inlet pipe 31 can be positioned on the horizontal plane by utilizing the boss locking principle. Therefore, the water outlet limiting boss 341 can limit the rotational deviation range of the water replenishment outlet pipe 35 relative to the water replenishment outlet head 34.

[0046] The top of the water inlet three-way chamber 12 protrudes from the installation cover 45, and the water replenishment inlet pipe 31 is connected to the top of the water inlet three-way chamber 12, so that water is taken in from the top of the water inlet three-way chamber 12. Similarly, since the connection between the water replenishment inlet pipe 31 and the water inlet three-way chamber 12 is located at the upper part of the installation cover 45, the water replenishment outlet pipe 35 can be easily installed and removed during installation and maintenance. The water replenishment inlet pipe 31 and the water replenishment outlet pipe 35 are both connected to the top of the installation cover 45, and are not installed on the side of the drain valve 4, so that there is no protruding structure on the side of the drain valve 4, thereby saving space and facilitating installation and maintenance. Similarly, in order to prevent the water replenishment inlet pipe 31 from rotating and deviating on the water inlet three-way cavity 12, a water inlet limiting boss 121 is provided on the top of the water inlet three-way cavity 12, and the water inlet limiting boss 121 can limit the rotational deviation range of the water replenishment inlet pipe 31 relative to the rotating switching member 11. The switching mechanism 1 and the regulating mechanism 2 are arranged opposite to each other, and the switching mechanism 1 and the regulating mechanism 2 are respectively located at the two ends of the full discharge water pipe 32 and the half discharge water pipe 33, so that the space above the drain valve 4 can be fully utilized.

[0047] The embodiment of the present invention also discloses a drain valve, which includes the full-row and half-row water replenishment control device as described above. The full-row and half-row water replenishment control device is provided with a switching mechanism 1, an adjusting mechanism 2 and a pipeline mechanism 3. The switching mechanism 1, the adjusting mechanism 2 and the pipeline mechanism 3 are all annularly built in the drain valve 4, which can greatly improve the space utilization rate of the drain valve 4, thereby saving space and improving the adaptability of the water tank size of the drain valve 4. The switching mechanism 1 includes a rotating switching member 11, which is linked with the full-row button 43 and the half-row button 44 of the drain valve, and the linkage method is to use the full-row drive arm 14 and the half-row drive arm 15 to drive the rotating switching member 11 to rotate counterclockwise or clockwise. The driving force driving the rotating switching member 11 to rotate is very small, which will not affect the driving of the full-row button 43 and the half-row button 44, so that the driving force of the full-row button 43 and the half-row button 44 is small, and has a good operating feel. In addition, the regulating mechanism 2 includes a full-row regulating knob 21 and a half-row regulating knob 22 for adjusting the water replenishment flow rate. The full-row regulating knob 21 and the half-row regulating knob 22 are both exposed on the surface of the button seat 41. When adjusting the flow rate, there is no need to remove the drain valve 4 to achieve adjustment, so it is simple and convenient to use.

[0048] The above are preferred embodiments of the present invention. It should be noted that, for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principles of the present invention. These improvements and modifications are also considered to be within the scope of protection of the present invention.
