Description

Technical Field

[0002] The double-row control device of the drain valve of the existing toilet water tank usually has a full drain control function and a half drain control function (or a large drain control function and a small drain control function). The existing double-row control device of the drain valve usually directly drives the rotating part set in the control box to rotate forward or reversely by rotating the wrench forward or reversely, and the rotating part then drives the starting part of the drain valve (such as a pull rope or a lifting rod) to move to start the drain valve to achieve full or half drain. Since the direction of rotation of the rotating part when performing full drain is opposite to the direction of rotation of the rotating part when performing half drain, the rotating part requires a larger movement space, resulting in a larger overall volume of the control box, which is not conducive to the spatial layout of the water tank.

Two first abutting portions 42 are symmetrically provided on the side wall of the second rotating member 4 along the circumferential direction, and two second abutting portions 51 are provided on the intermediate rotating member 5 corresponding to the two first abutting portions 42. Of course, in other embodiments, the other end of the intermediate rotating member 5 may also be directly rotatably mounted on the box body 1 and coaxially arranged with the second rotating member 4, which can also achieve the purpose of the present invention.

The first rotating member 3, the second rotating member 4 and the intermediate rotating member 5 are all arranged in a cavity formed by the upper shell 11 and the lower shell 12. One end of the rotating shaft 21 is fixedly connected to the wrench 2, and the other end of the rotating shaft 21 passes through the upper shell 11 and is connected to the second rotating member 4 and cannot rotate relative to the second rotating member 4.

[0048] See also Figures 2 to 8 In this embodiment, the starter 6 of the drain valve is a pull rope, one end of which is connected to one end of the first rotating member 3, and the other end of the pull rope extends out of the box body 1.

[0049] See also Figures 2 to 8 In this embodiment, a button assembly 9 is also included. The button assembly 9 includes a full row of buttons (not shown in the figure), a half row of buttons (not shown in the figure), a push rod 92 and a button seat 91 mounted on the box body 1. The full row of buttons, the half row of buttons and the push rod 92 are respectively mounted on the button seat 91 through elastic reset members (not shown in the figure) so as to be reciprocatingly slidable. The full row of buttons and the half row of buttons are respectively pressed against the first rotating member 3 through the push rod 92 to drive the first rotating member 3 to rotate in the same direction. When one of the full row of buttons and the half row of buttons is pressed, the push rod 92 is driven to press the first rotating member 3 so that the first rotating member 3 is rotated to the position of the first angle. When the other of the full row of buttons and the half row of buttons is pressed, the push rod 92 is driven to press the first rotating member 3 so that the first rotating member 3 is rotated to the position of the second angle.

[0050] like Figure 3 As shown, in this embodiment, in the initial state, the wrench 2, the first rotating member 3, the second rotating member 4 and the intermediate rotating member 5 are all located in the initial positions, and under the action of the first return torsion spring 7 and the second return torsion spring 8, the first abutment portion 42 and the second abutment portion 51 abut against each other, and the fourth abutment portion 52 abuts against one end of the third abutment portion 32 close to the first tooth portion 31, and the first tooth portion 31 and the second tooth portion 41 are not engaged.

[0051] In this embodiment, when full displacement is required, the wrench 2 is pulled to make it rotate forward. Figure 3 or Figure 5 Taking the direction shown in the figure as an example, the spanner 2 is rotated counterclockwise, the spanner 2 drives the second rotating member 4 to rotate forward, the first abutting portion 42 and the second abutting portion 51 are disengaged from the abutting cooperation, and the intermediate rotating member 5 will not rotate with the second rotating member 4 due to the obstruction of the limited position portion 34 and the action of the second reset torsion spring 8, and remain in the initial position. At the same time, the second rotating member 4 realizes synchronous reverse rotation with the first rotating member 3 through the external meshing cooperation of the first tooth portion 31 and the second tooth portion 41, thereby driving the first rotating member 3 to rotate a first angle to make the starting member 6 move a longer stroke to open the drain valve for full drainage. Figure 5 The diagram shows a state in which the wrench 2 of the present invention rotates forward to drive the first rotating member 3 to rotate by a first angle so that the drain valve is fully opened; after the drain valve is fully opened, the wrench 2 is released, and the first rotating member 3 rotates and resets under the action of the first reset torsion spring 7, and at the same time, the first rotating member 3 drives the second rotating member 4 to rotate and reset, and the second rotating member 4 drives the wrench to rotate and reset, or the second rotating member 4 rotates and resets under the driving action of the wrench 2, and the wrench 2 can be rotated and reset by the elastic member or by its own gravity to return to the initial state;

[0052] Alternatively, the full-drain button can be pressed to drive the push rod 92 to press the first rotating member 3 so that the first rotating member 3 rotates by a first angle to open the drain valve for full drainage. During this process, the wrench 2, the second rotating member 4 and the intermediate rotating member 5 are always located at the initial position under the action of the second reset torsion spring 8. Figure 7 The figure shows a schematic diagram of the state in which the full-drain button of the present invention is pressed through the push rod 92 to drive the first rotating member 3 to rotate to a first angle so that the drain valve is fully opened; after the drain valve is fully opened, the full-drain button is released, the push rod 92 is reset under the action of the elastic reset member, and the first rotating member 3 is rotated and reset under the action of the first reset torsion spring 7.

[0053] In this embodiment, when half a row is needed, the wrench 2 is turned to reverse the rotation. Figure 3 or Figure 6 Taking the direction shown in the figure as an example, the spanner 2 is rotated clockwise, the spanner 2 drives the second rotating member 4 to reverse, the first tooth portion 31 is separated from the second tooth portion 41, the second rotating member 4 is rotated synchronously with the intermediate rotating member 5 in the same direction through the abutment cooperation between the first abutment portion 42 and the second abutment portion 51, and the intermediate rotating member 5 is rotated synchronously with the first rotating member 3 in the same direction through the sliding abutment cooperation between the third abutment portion 32 and the fourth abutment portion 52, thereby driving the first rotating member 3 to rotate a second angle to make the starter 6 move a shorter stroke to open the drain valve for semi-drainage. Figure 6 The diagram shows a state in which the wrench 2 is reversed to drive the first rotating member 3 to rotate to a second angle so that the drain valve is opened half a row; after the drain valve is opened half a row, the wrench 2 is released, the first rotating member 3 is rotated and reset under the action of the first reset torsion spring 7, and the intermediate rotating member 5 is rotated and reset under the action of the second reset torsion spring 8, and the intermediate rotating member 5 drives the second rotating member 4 to rotate and reset through the abutment cooperation between the first abutment portion 42 and the second abutment portion 51, and the second rotating member 4 then drives the wrench to reset, or the wrench 2 can choose to rotate and reset through the elastic member or by its own gravity to drive the second rotating member 4 to rotate and reset, and return to the initial state;

[0054] Alternatively, the half-drain button can be pressed to drive the push rod 92 to press the first rotating member 3 so that the first rotating member 3 rotates by a second angle to open the drain valve for half-drainage. During this process, the wrench 2, the second rotating member 4 and the intermediate rotating member 5 are always located at the initial position under the action of the second reset torsion spring 8. Figure 8 The figure shows a schematic diagram of the state in which the half-row button of the present invention is pressed through the push rod 92 to drive the first rotating member 3 to rotate to a second angle so that the drain valve is opened half a row; after the drain valve is opened half a row, the half-row button is released, the push rod 92 is reset under the action of the elastic reset member, and the first rotating member 3 is rotated and reset under the action of the first reset torsion spring 7.
