Description

Technical Field

[0001] The present invention relates to the technical field of toilet flushing, and more particularly to a toilet flushing linkage device that is convenient for disassembly and assembly. Background Art

[0002] Currently, traditional toilets on the market are all flushed by manually pressing the flushing button. Since the toilet sanitation conditions are generally poor, especially in public toilets where different people use them, this manual pressing method will increase the risk of bacterial infection. At the same time, it is inevitable that someone will forget to flush after using the toilet.

[0003] To solve these problems, Chinese Patent CN201721719686.5 proposed a toilet flushing device and an intelligent toilet, which drives a telescopic rod to press the flushing button through a driving device, replacing the manual pressing of the flushing button and enabling automatic flushing. However, its flushing device has a complex structure, and the installation and matching requirements of the telescopic rod and the flushing button are high, which is not convenient for disassembly and installation in actual engineering scenarios, resulting in a significant reduction in the construction efficiency of workers. Therefore, it is necessary to design a flushing device that is convenient for disassembly and assembly. Summary of the Invention

[0004] The present invention overcomes the problem of inconvenient installation of the toilet flushing device and the linkage mechanism in the above-mentioned prior art, and provides a toilet flushing linkage device that is convenient for disassembly and assembly.

[0005] In this technical solution, a toilet flushing linkage device that is convenient for disassembly and assembly is provided, including a housing, a driver, a pressing member, and a transmission mechanism. The driver and the transmission mechanism are arranged on the housing. The transmission mechanism includes a transmission gear, a driven member, an actuator, and a connecting rod. The transmission gear is fixedly connected to the output shaft of the driver and is in transmission connection with the driven member. The driven member is connected to the actuator, the driven member is slidably connected to the housing, the actuator is rotatably arranged on the housing, one end of the connecting rod is rotatably connected to the actuator, and the pressing member is inserted into the housing and connected to the actuator. It further includes a flushing valve pull rope, and the flushing valve pull rope is connected to the other end of the connecting rod.

[0006] In the present invention, the flushing valve pull rope and the transmission mechanism are separately and independently designed, and the flushing valve pull rope can be clamped on the housing. Such a split design is more user-friendly and the installation is more convenient and fast.

[0007] The actuator in the present invention is an irregular triangular plate, which is provided with a first protruding end, a second protruding end, a third protruding end and a mounting hole. The first protruding end is connected to the driven member, the second protruding end is rotatably connected to the connecting rod, the third protruding end is connected to the pressing member. The structure of the irregular triangular plate is smaller in volume compared with general structures such as worm gears, screws, telescopic rods, etc. At the same time, since the three protruding ends of the irregular triangular plate can all be used as connection stress points, the overall design and installation occupy much less space.

[0008] As a further improved structural form, the above-mentioned housing is further provided with a first positioning post, a chute, a through hole, a first mounting groove and a second mounting groove. The actuator is rotatably sleeved on the first positioning post through the mounting hole, the pressing member is inserted into the through hole, and one end of the pressing member is in close contact with the third protruding end. When the driver is powered on and operates normally, the actuator rotates around the first positioning post by a certain angle under the drive of the driver, and drives the up and down movement of the connecting rod, thereby pulling the flush valve pull rope to complete the automatic flushing operation. When the driver is powered off or fails, under the manual pressing action of the pressing member, the smaller end of the pressing member applies force to the third protruding end, drives the actuator to rotate, and the actuator pulls the flush valve pull rope through the connecting rod to complete the manual flushing operation.

[0009] As a further improved structural form, a reset member is sleeved on the first positioning post between the above-mentioned housing and the actuator. The reset member is a torsion spring. One protruding end of the torsion spring is embedded in the actuator, and the other protruding end is pressed on the housing. The actuator rotates under the action of the driver, and at the same time compresses the torsion spring. The torsion spring stores energy. The driver reverses, and at the same time uses the torsion spring to release energy to bounce the actuator back to the initial position.

[0010] As a further improved structural form, the above-mentioned driven member is a slider, which is provided with a shoulder that cooperates with the chute, and also provided with a first protrusion and a second protrusion that cooperate with the first protruding end. The slider slides horizontally in the chute through the shoulder. During the horizontal sliding process, the first protrusion contacts the first protruding end of the actuator and applies force to the first protruding end to drive the actuator to rotate.

[0011] As a further improved structural form, the above-mentioned connecting rod is provided with a positioning hole and a clamping hole. The connecting rod is rotatably connected to the second protruding end through the positioning hole, and the connecting rod is connected to the flush valve pull rope through the clamping hole. When the second protruding end rotates, it drives the connecting rod to move, thereby pulling the flush valve pull rope.

[0012] As a further improved structural form, a clamping ball that cooperates with the clamping hole is provided at the end of the flush valve pull rope close to the connecting rod. The flush valve pull rope is clamped to the connecting rod through the clamping ball. During installation, only by sleeving the clamping ball into the clamping hole can the connecting rod be connected to the flush valve pull rope.

[0013] As a further improved structural form, a fixing block is also provided at one end of the flushing valve pull rope close to the connecting rod. The fixing block is provided with a third protrusion and a fourth protrusion respectively cooperating with the first installation groove and the second installation groove. The flushing valve pull rope is directly clamped on the housing through the fixing block, which is convenient and fast.

[0014] As a further improved structural form, the second extended end is provided with a second positioning post. The connecting rod is rotatably sleeved with the second positioning post of the second extended end through a positioning hole. When the actuator rotates, the second extended end and the connecting rod can rotate around the second positioning post, so that the connecting rod moves upward.

[0015] As a further improved structural form, a rope sleeve is sleeved on the flushing valve pull rope, and the rope sleeve protects the flushing valve pull rope and extends its service life.

[0016] Compared with the prior art, the beneficial effects are as follows:

[0017] (1) In the present invention, the flushing valve pull rope and the transmission mechanism are separately and independently designed. The flushing valve pull rope is clamped and fixed on the housing through a fixing block. Such a split design is more user-friendly and the installation is more convenient and fast, greatly improving the installation efficiency.

[0018] (2) By setting an independent pressing member in the present invention, the toilet can be manually operated to flush water even when powered off, making it more convenient to use.

[0019] (3) The toilet flushing linkage device that is convenient for disassembly and assembly in the present invention drives the driven member and the actuator to move through a driver. The actuator pulls the flushing valve pull rope through a connecting rod to complete the operation of automatic flushing. It has few components, a simple structure, a small volume, and is convenient for installation. BRIEF DESCRIPTION OF THE DRAWINGS

[0043] As Figure 4 shown, the actuator 5 is an irregular triangular plate. The irregular triangular plate is provided with a first protruding end 51, a second protruding end 52, a third protruding end 53, and a mounting hole 54. The first protruding end 51 is connected to the driven member 4. The second protruding end 52 is rotatably connected to the connecting rod 6. The third protruding end 53 is connected to the pressing member 9. The structure of the irregular triangular plate is smaller in volume compared to general structures such as worm gears, screws, and telescopic rods. At the same time, since the three protruding ends of the irregular triangular plate can all be used as force application points, the overall design and installation occupy much less space.

[0044] As Figure 4 shown, the housing 1 is further provided with a first positioning post 12, a chute 13, a through hole 14, a first mounting groove 15, and a second mounting groove 16. The actuator 5 is rotatably sleeved on the first positioning post 12 through the mounting hole 54. The pressing member 9 is inserted into the through hole 14, and one end of the pressing member 9 is in close contact with the third protruding end 53. When the driver 2 is powered on and operates normally, the actuator 5 rotates a certain angle around the first positioning post 54 under the drive of the driver 2, and drives the up and down movement of the connecting rod 6, thereby pulling the flush valve pull rope 7 to complete the automatic flushing operation. When the driver 2 is powered off or fails, under the manual pressing action, the smaller end of the pressing member 9 applies a force to the third protruding end 52, driving the actuator 5 to rotate. The actuator 5 pulls the flush valve pull rope 7 through the connecting rod 6 to complete the manual flushing operation.

[0045] As Figure 5 , 6As shown, the follower 4 is a slider. A shoulder 41 that mates with the chute 13 is provided on the slider. The slider uses the shoulder 41 to slide horizontally in the chute 13. The follower 4 is a slider. A shoulder 41 that mates with the chute 13 is provided on the slider. A first protrusion 43 and a second protrusion 44 that are respectively connected to the first extension 51 are also provided. The slider slides horizontally in the chute 13 through the shoulder 41. During the horizontal sliding process, the first protrusion 43 contacts the first extension 51 of the actuator 5 and applies a force to the first extension 51 to drive the actuator 5 to rotate..

[0046] As Figure 7 shown, one end of the pressing member 9 is in close contact with the third extension 53. Under the manual pressing action, the smaller end of the pressing member 9 applies a force to the third extension 53 to drive the actuator 5 to rotate. The actuator 5 pulls the flushing valve cable 7 through the connecting rod 6.

[0047] As Figure 8 shown, it further includes a flushing valve cable 7. The flushing valve cable 7 is connected to the other end of the connecting rod 6. The connecting rod is rotatably connected to the second extension 52 of the follower 5. When the actuator 5 rotates, it pulls the flushing valve cable 7 through the connecting rod 6 to achieve the flushing operation.

[0048] As Figure 9 shown, a fixing block 72 is further provided at one end of the flushing valve cable 7 close to the connecting rod 6. The fixing block 72 is provided with a third protrusion 73 and a fourth protrusion 74 that respectively cooperate with the first mounting groove 15 and the second mounting groove 16. The flushing valve cable 7 is directly clamped on the housing 1 through the fixing block 72, which is convenient and fast.

[0049] In this embodiment, a reset member 8 is sleeved on the first positioning post 12 between the housing 1 and the actuator 5. The reset member 8 is a torsion spring. One extension of the torsion spring is embedded in the actuator 5, and the other extension is pressed on the housing 1. The actuator 5 rotates under the action of the driver 2, and at the same time compresses the torsion spring. The torsion spring stores energy. After the driver 2 is powered off, the torsion spring releases energy and rebounds the actuator 5 back to the initial position.

[0050] In this embodiment, the connecting rod 6 is provided with a positioning hole 61 and a clamping hole 62.

When the second extension 52 rotates, it drives the connecting rod 6 to move, thereby pulling the flushing valve cable 7.

[0051] In this embodiment, a clamping ball 71 that cooperates with the clamping hole 62 is provided at the end of the flushing valve cable 7 close to the connecting rod 6. The flushing valve cable 7 is clamped to the connecting rod 6 through the clamping ball 71. During installation, only by inserting the clamping ball 71 into the clamping hole 62 can the connecting rod 6 be connected to the flushing valve cable 7.

[0052] In this embodiment, a second positioning post 55 is provided at the second protruding end 52. The connecting rod 6 is rotatably sleeved with the second positioning post 55 of the second protruding end 52 through the positioning hole 61. When the actuator 5 rotates, the second protruding end 52 and the connecting rod 6 can rotate around the second positioning post 55, so that the connecting rod 6 moves upward.

[0053] In this embodiment, a rope sleeve 75 is sleeved on the flush valve pull rope 7. The rope sleeve 75 protects the flush valve pull rope 7 and extends its service life.

[0054] In this embodiment, the driven member 4 is provided with a rack 42 that meshes and drives with the transmission gear 3. The rack 42 meshes with the transmission gear. Driven by the transmission gear 3, the driven member 4 moves in the horizontal direction.

[0055] The automatic flushing working process in this embodiment:

[0056] As Figure 2 or Figure 3 shown, when the external power supply is connected and flushing is required, the driver 2 is powered on and operates. The transmission gear 3 drives the driven member 4 to move horizontally to the left. The first protrusion 41 on the driven member 4 applies a force to the first protruding end 51 of the actuator 5. The actuator 5 rotates counterclockwise around the first positioning post 12 by a certain angle. During this process, the actuator 5 compresses the torsion spring and the second protruding end 52 on the actuator 5 drives the connecting rod 6 to move upward, thereby pulling the flush valve pull rope 7 fixed on the connecting rod 6. Then the driver 2 rotates in reverse, the torsion spring releases energy, drives the actuator 5 to rotate clockwise, and returns to the initial position, completing an automatic flushing operation.

[0057] The manual flushing working process in this embodiment:

[0058] As Figure 7 shown, when the external power supply is not connected to the driver 2 or the driver 2 cannot work properly due to various faults and flushing is required, by manually pressing the pressing member 9, the actuator 5 is driven to rotate counterclockwise by a certain angle. During this process, the actuator 5 compresses the torsion spring and the second protruding end 52 on the actuator 5 drives the connecting rod 6 to move upward, thereby pulling the flush valve pull rope 7 fixed on the connecting rod 6. Then release the pressing member 9, the torsion spring releases energy, drives the actuator 5 to rotate clockwise, and returns to the initial position, completing a manual flushing operation.

[0059] The installation method of the flush valve pull rope and the transmission mechanism in this embodiment:

[0060] As Figure 8 、 9As shown, first place the clamping ball 71 at one end of the flushing valve pull rope 7 into the clamping hole 62 of the connecting rod 6, then place the fixing block 72 on the housing 1. The third protrusion 73 and the fourth protrusion 74 are respectively corresponding to the positions of the first installation groove 15 and the second installation groove 16. Then press the fixing block 72 to make the third protrusion 73 and the fourth protrusion 74 of the fixing block 72 snap into the first installation groove 15 and the second installation groove 16 to complete the installation. When disassembling, only apply force beside the third protrusion 73 and the fourth protrusion 74 and pry it off.
