Description

Technical Field

[0001] The invention mainly relates to the technical field of sanitary ware, in particular to a spring type rotary flushing valve. Background Art

[0002] In daily life, squat toilets (abbreviated as squat toilets) are widely used. Many public toilets, office buildings, factories, shopping malls, concentrated residential areas and other places are basically equipped with squat toilets, which bring convenience to people's lives, facilitate daily use, and prevent the spread of some diseases. The flushing devices used by people after defecation include water tank type, electric induction type, foot-operated type, and hand-pressed type. The hand-pressed type is currently more widely used because it is not limited by power supply. After defecation, press the flush switch by hand. After flushing, the hand-pressed switch slowly pops outward under the elastic force of the spring to turn off the water source and stop flushing, which is convenient for people.

[0003] However, in actual use, the spring often fails and the switch cannot pop out. Since most people flush and leave, the tap water is always in the flushing state, wasting water. After the switch is pressed, the button is in the inside state, even if you want to turn it off manually, it is difficult to turn the switch button, resulting in a waste of water resources. At this time, a plumber must be found for repairs. Some people have thought of many ways, but none of them can solve the problem well. How to solve it has always been a difficult problem.

The flush valve 1 comprises a valve body 101, a valve seat 102, and a valve core 103. The outer wall of the valve seat 102 is threadedly engaged with the inner wall of the valve body 101. A water channel 1031 runs through the valve core 103. The valve core 103 is movably arranged inside the valve body 101.

A chamber 4022 is provided inside the transmission shaft 402. The torsion spring 403 is located in the chamber 4022. The two ends of the torsion spring 403 are respectively connected to the inner wall of the chamber 4022 and The outer wall of the connecting shaft 401 is connected by clamping, and a spanner slot 4021 is provided on the outer wall of the end of the transmission shaft 402 close to the valve seat 102, and a sealing cover 5 is sleeved on the outer side of the transmission shaft 402, and the inner wall of the sealing cover 5 is threadedly connected to the outer wall of the transmission shaft 402, and a sealing gasket 501 is provided between the end of the transmission shaft 402 and the inner wall of the sealing cover 5, and the end of the connecting shaft 401 away from the valve core 103 passes through the wall of the sealing cover 5 and the outer wall is provided with an inner tooth 4011, and the end face of the connecting shaft 401 is provided with a sleeve 404 through a thread sleeve, and a switch handle 4041 is fixed on the sleeve 404; The auxiliary component 7 is arranged in the protective cover 6, and the auxiliary component 7 is connected to the rotating component 4. The protective cover 6 is composed of a first cover body 601 and a second cover body 602. The side walls of the first cover body 601 and the second cover body 602 are provided with card slots at the sealing cover 5 and the connecting shaft 401. The side wall of the first cover body 601 is provided with a plug-in slot 6011, and the side wall of the second cover body 602 is welded with a plug-in board 6021, and the plug-in board 6021 is plug-connected to the plug-in slot 6011. The first cover body 601 and the second cover body 602 are fixedly connected to the wall 3 by screws.

[0022] During installation, bury the water pipe 2 and the valve body 101 in the groove of the wall 3, seal it with cement, insert the valve core 103 into the valve body 101, then clamp the wrench in the wrench clamping groove 4021, screw the valve seat 102 into the valve body 101 through threads and seal it with it. At this time, the valve seat 102 and the transmission shaft 402 will be inserted into the connecting shaft 401 of the valve core 103, then put the torsion spring 403 into the chamber 4022, and clamp the two ends with the inner wall of the chamber 4022 and the outer wall of the connecting shaft 401 respectively, then screw the sealing cover 5 on the transmission shaft 402 through threads, and seal it with the sealing gasket 501; At this time, the first cover body 601 of the protective cover 6 is moved in from the side, so that the groove contacts the outer wall of the sealing cover 5 and the connecting shaft 401 respectively, and the connecting piece of the auxiliary component 7 (the first gear 702 in the text) will mesh with the inner gear 4011 during the movement, and then the first cover body 601 is fixed to the wall 3 by screws, and then the second cover body 602 is moved in from the other side until the plug-in board 6021 is inserted into the plug-in groove 6011, and then the second cover body 602 is fixed to the wall 3 by screws, and the splicing of the protective cover 6 is completed to achieve aesthetic and protective effects, and finally the sleeve 404 together with the switch handle 4041 is threadedly sleeved on the end of the connecting shaft 401, so that the installation process is simple and fast through threaded connection and slot plug-in, and it is convenient to disassemble and replace the torsion spring 403 when it fails in the later stage; When in use, the user manually rotates the switch handle 4041 clockwise to drive the connecting shaft 401 to rotate through the sleeve 404, thereby driving the valve core 103 to rotate in the valve body 101, that is, rotating 180 degrees. At this time, the two water pipes 2 are connected with the water channel 1031. When the connecting shaft 401 rotates, the torsion spring 403 stores energy and drives the auxiliary component 7 to move through the inner gear 4011. At this time, tap water flows into the squat toilet or other objects through the water channel 1031 and the water pipe 2; After flushing, when the user's hand is separated from the switch handle 4041, the torsion spring 403 releases energy, and the auxiliary component 7 moves in the opposite direction, thereby controlling the connecting shaft 401 and the valve core 103 to automatically return to their original positions, shutting off the water source, thereby further improving the reliability of resetting. Even if the torsion spring 403 fails, the auxiliary component 7 can still play a resetting role, thereby extending the maintenance period caused by the failure of the torsion spring 403 and reducing the maintenance frequency.

[0023] See also Figure 4 , Figure 5 and Figure 7 As shown, the auxiliary component 7 includes a support plate 701, a first gear 702 and a second gear 703. The tooth surface of one side of the first gear 702 is meshed with the inner gear 4011, and the tooth surface of the other side of the first gear 702 is meshed with the tooth surface of the second gear 703. A shaft 7021 is fixedly penetrated at the center of the first gear 702, and a rotating shaft 7031 is fixedly penetrated at the center of the second gear 703. One end of the shaft 7021 and the rotating shaft 7031 are both rotatably connected to the plate surface of the support plate 701. A limiting circular plate 704 is symmetrically sleeved on the outer wall of one end of the rotating shaft 7031 away from the supporting plate 701, a pull rope 705 is arranged between the two limiting circular plates 704, one end of the pull rope 705 is wound and connected with the outer wall of the rotating shaft 7031, and the other end of the pull rope 705 is fixedly connected with a counterweight block 706, the diameter of the first gear 702 is smaller than the diameter of the second gear 703, one end of the supporting plate 701 is fixedly connected to the inner wall of the first cover body 601, and the two limiting circular plates 704 are fixedly connected to the outer wall of the rotating shaft 7031; A contact plate 8 is provided below the counterweight block 706, one end of which is fixedly connected to the inner wall of the first cover body 601, a battery compartment 801 is provided below the contact plate 8, an acceleration sensor is embedded in the counterweight block 706, and the battery compartment 801 is electrically connected to the acceleration sensor through a wire.

[0024] When the user controls the valve core 103 to open and the water channel 1031 is connected to the two water pipes 2, the inner gear 4011 on the connecting shaft 401 drives the meshing first gear 702 to rotate, and the first gear 702 drives the meshing second gear 703 on the other side to rotate, and the second gear 703 drives the rotating shaft 7031 passing through the center to rotate, and the rotating rotating shaft 7031 reels the wound pull rope 705, wherein the two limiting circular plates 704 can limit the winding position of the pull rope 705 when it is reeled in, avoiding contact with the second gear 703, and the reeled pull rope 705 drives the counterweight block 706 to move upward, and the moving speed of the counterweight block 706 is detected by the acceleration sensor during the movement process, thereby completing the opening of the flushing valve 1; After the user separates from the switch handle 4041, the torsion spring 403 releases energy, and the counterweight 706 moves downward due to gravity. At this time, the pull rope 705 is stretched and drives the rotating shaft 7031 to rotate, and the rotating shaft 7031 drives the second gear 703 to rotate in the opposite direction. The second gear 703 transmits the reverse rotation force to the connecting shaft 401 through the meshing first gear 702, thereby controlling the valve core 103 to automatically rotate back to its original position and shut off the water source. Even if the torsion spring 403 fails, the counterweight 706 and the pull rope 705 structure can still play a certain resetting role. However, due to the lack of energy from the torsion spring 403, the weight close to the counterweight 706 will reduce the recovery speed. At this time, the acceleration sensor sends the detected data to the microcontroller to calculate the downward movement speed of the counterweight 706. When the speed is lower than the preset threshold, an alarm signal can be triggered to indicate that the torsion spring 403 may have failed.

[0025] The working principle of the present invention is: When in use, the user manually rotates the switch handle 4041 clockwise to drive the connecting shaft 401 to rotate through the sleeve 404, thereby driving the valve core 103 to rotate in the valve body 101, that is, rotating 180 degrees. At this time, the two water pipes 2 are connected to the water channel 1031. When the connecting shaft 401 rotates, the torsion spring 403 will store energy and drive the meshing first gear 702 to rotate through the inner gear 4011. The first gear 702 drives the meshing second gear 703 on the other side to rotate. The second gear 703 The rotating shaft 7031 passing through the center is driven to rotate, and the rotating rotating shaft 7031 performs a reeling operation on the wound pull rope 705, wherein the two limiting circular plates 704 can limit the winding position of the pull rope 705 when it is reeled in, so as to avoid contact with the second gear 703, and the reeled pull rope 705 will drive the counterweight block 706 to move upward, and the moving speed of the counterweight block 706 is detected by the acceleration sensor during the movement process, and the flushing valve 1 is opened, and at this time, the tap water flows into the squat toilet or other objects of use through the water channel 1031 and the water pipe 2; After flushing, when the user separates from the switch handle 4041, the torsion spring 403 releases energy, and the counterweight 706 moves downward due to gravity. At this time, the pull rope 705 is stretched and drives the rotating shaft 7031 to rotate, and the rotating shaft 7031 drives the second gear 703 to rotate in the opposite direction. The second gear 703 transmits the reverse rotation force to the connecting shaft 401 through the meshing first gear 702, thereby controlling the valve core 103 to automatically rotate back to its original position and shut off the water source. Even if the torsion spring 403 fails, the counterweight 706 and the pull rope 705 structure can still play a certain resetting role, but due to the lack of energy from the torsion spring 403, the weight close to the counterweight 706 will reduce the recovery speed. At this time, the acceleration sensor sends the detected data to the microcontroller to calculate the downward movement speed of the counterweight 706. When the speed is lower than the preset threshold, an alarm signal can be triggered to indicate that the torsion spring 403 may fail.
