[0001] The invention relates to the technical field of drainers, in particular to an overflow and drainage integrated drainer. Background Art

[0002] Faucets and sinks are essential facilities in daily life, which bring great convenience to people. However, existing sinks on the market generally have unavoidable problems. For example, after turning on the faucet or valve, you need to wait in front of the faucet and wait until the water level reaches the required position before manually closing it, which wastes time. At the same time, if you forget to close the faucet or valve, water will overflow from the sink, causing flooding and property losses, and in serious cases, safety accidents may occur.

[0003] In the prior art, the overflow problem is usually solved by opening an overflow hole at a specific height in a water container. When the water exceeds this height, it will flow out of the hole to prevent the water from overflowing and causing other losses. Generally, the overflow hole and the drainage hole are connected to each other, so that the overflowing water can be passed into the sewer pipe. However, opening an overflow hole on a water container will affect the installation process of the container, and bacteria and residues are easily bred in the overflow hole.

[0004] Therefore, it is necessary to design a device that can discharge the liquid exceeding a predetermined height in time and avoid overflow without opening an overflow hole in the water container. Summary of the invention

[0025] In addition, the overflow channel 3-1 and the auxiliary drainage channel 3-2 are both inclined, and the overflow chamber 3-3 is located at one end of the overflow channel 3-1 and the auxiliary drainage channel 3-2 that is inclined upward, so as to improve the effect of the preset overflow water level height in the water container, and also facilitate the flow direction of the overflow water in the overflow chamber 3-3 and the auxiliary drainage channel 3-2.

[0026] The transmission gear set 6 includes a housing 6-1, a return spring 6-2 arranged in the housing 6-1, and a driving gear 6-3 and a driven gear 6-4 that mesh with each other. In addition, a rack 9 is formed on one end of the film transmission rod 7 corresponding to the driving gear 6-3, and at least one hook notch 10 is integrally formed on one end of the piston transmission rod 8 corresponding to the driven gear 6-4. The driving gear 6-3 is integrally formed with a first gear tooth 6-3-1 corresponding to the rack 9, and the driving paper wheel 6-3 is integrally formed with a second gear tooth 6-3-2 corresponding to the driven gear 6-4. The film transmission rod 7 is connected to the driving gear through the rack 9, the first gear tooth 6-3-1, and the driven gear 6-3 meshing linkage, through the meshing transmission of the driving gear 6-3 and the driven gear 6-4, the membrane transmission rod 7 and the piston transmission rod 8 move in the same direction; at the same time, one end of the return spring 6-2 is fixed in the shell 6-1, and the other end of the return spring 6-2 is fixed to the driving gear 6-3, so that after the water level in the water container drops, the elastic force of the return spring 6-2 can make the driving gear 6-3 rotate back, drive the water sealing piston 5 to seal the auxiliary drainage channel 3-2, and prevent excessive discharge of water from the overflow valve seat 3; the driven gear 6-4 is integrally connected with a linkage hook 11 corresponding to the piston transmission rod 8, and the bent hook portion of the linkage hook 11 extends into The hook slot 10 has a certain buffer distance, and the hook of the linkage hook 11 moves slowly from one end of the hook slot 10 to the other end of the hook slot 10, and then the piston transmission rod 8 is pulled by pulling the hook slot 10. When the linkage hook 11 moves in the hook slot 10, it means that the water level in the water container is constantly rising. When it exceeds the preset height, the hook of the linkage hook 11 just reaches the end of the hook slot 10. Then, under the pulling of the linkage hook 11, the piston transmission rod 8 drives the water sealing piston 5 to leave the secondary drainage channel 3-2, so that the excess water in the water container passes through the overflow port 1-1, the overflow channel 3-1, and the overflow cavity 3- 3. The auxiliary drainage channel 3-1 and the auxiliary drainage port 1-2 are used for discharge; and the water level of the overflow water in the water container can be changed by changing the linkage hook 11 to cooperate with the hook groove 10 at other positions; in addition, the driving gear 6-3 is convex to form an arc-shaped protrusion 6-3-3 on one side corresponding to the first gear tooth 6-3-1, and the first gear tooth 6-3-1 is located on the side wall of the arc-shaped protrusion 6-3-3. By arranging the first gear tooth 6-3-1 on the arc-shaped protrusion 6-3-3 to increase the number of teeth of the first gear tooth 6-3-1, the transmission speed ratio of the membrane transmission rod 7 and the piston transmission rod 8 is realized to increase the height of the set water level in the water container.

[0027] The overflow chamber 3-3 includes a water flow space 3-3-1 connected to the overflow channel 3-1 and the auxiliary drainage channel 3-2, and an activity space 3-3-2 that limits the movement of the pressure sensing membrane 4 and the water sealing piston 5, respectively. The water sealing piston 5 includes a piston rod 5-1 and a piston 5-2. A pressure reducing valve cover 12 and a sealing sheet 13 are inserted into the piston rod 5-1 at the activity space 3-3-2 corresponding to the water sealing piston 5. The sealing sheet 13 is on the water sealing piston 5. The pressure reducing valve cover 12 is movably inserted into the piston rod 5-1. A one-way valve 14 is provided on the end surface of the pressure reducing valve cover 12 facing the water flow direction, so that the piston 5 -2 After the secondary drainage channel 3-2 is blocked again, the one-way valve 14 is opened to drain the water between the pressure reducing valve cover 12 and the sealing plate 13 in time. At the same time, the piston 5-2 is in the shape of a truncated cone. Through the cooperation of the pressure reducing valve cover 12 and the sealing plate 13, when water flows into the water flow space, water enters between the pressure reducing valve cover 12 and the sealing plate 13 from the gap between the pressure reducing valve cover 12 and the piston rod 5-1, offsetting the pressure of the water pressure in the water flow space on the piston 5-2, and assisting the piston 5-2 to open the secondary drainage channel 3-2. At the same time, the shape of the piston 5-2 also reduces the pressure of the water pressure on the piston 5-2, making it easier to open the secondary drainage channel 3-2.

[0028] A drain plug 16 is provided at the water outlet of the water container, and an overflow channel 17 is formed between the drain plug 16 and the water outlet of the water container. The drain plug 16 is linked with the sealing plug 2. The drain plug 16 is elastically provided at the water outlet of the water container. The drainage waterway in the sewer pipe is opened by pressing the drain plug 16, so that the sealing plug 2 leaves the overflow outlet 1-1 and the auxiliary drain outlet 1-2, thereby achieving the purpose of water discharge. Specific embodiment 2

[0030] like Figure 6 As shown, the difference from specific embodiment 1 is that a drainage cavity 15 is sleeved at the position below the overflow valve seat 3 of the sewer pipe 1, and a drainage port 15-1 which can be connected to an external pipe is opened on the side wall of the drainage cavity 15, and the bottom end of the sewer pipe 1 is located in the drainage cavity 15 and extends downward to below the drainage port 15-1. By setting the drainage cavity 15, water can be accumulated in the drainage cavity 15 to prevent the odor of the external drainage pipe from returning from the drainage port 15-1 to pollute the indoor air. An end cover 19 is threadedly connected to the bottom of the drainage cavity 15, and a sealing ring is provided between the end cover 19 and the drainage cavity 15 to prevent water leakage. The particulate matter precipitated in the drainage cavity 15 can be cleaned by removing the end cover 19. A lifting rod 18 is connected to the bottom end of the drainage cavity 15, and the lifting rod 18 passes through the end cover and is connected to the water sealing plug 2, so that the drainage purpose can be achieved without putting hands into the water.

[0031] Working principle: the dewatering device is connected to the drain outlet of the water container. During normal drainage, the water sealing plug 2 can be moved away from the position between the overflow outlet 1-1 and the auxiliary drain outlet 1-2 by lifting the pull rod 18 or pressing the elastic drain plug 16, thereby opening the drainage waterway in the sewer pipe 1, and the water is directly discharged from the sewer pipe; when water is stored, the water sealing plug 2 is blocked between the overflow outlet 1- and the auxiliary drain outlet 1-2 to block the drainage waterway in the sewer pipe 1. At this time, water begins to accumulate in the water storage container. As the water level continues to rise, the pressure sensing membrane 4 in the overflow chamber pushes the membrane transmission rod 7 to move under the action of water pressure, and the rack 9 on the membrane transmission rod 7 drives the active gear 6-3 to rotate, and the active gear 6-3 drives The driven gear 6-4 rotates, and the driven gear 6-4 rotates to make the linkage hook 11 move in the hook slot 10. Finally, the linkage hook 11 reaches the end of the hook slot 10 and pulls the piston transmission rod 8 through the hook slot 10 to move, so that the water-sealing piston 5 leaves the channel opening of the auxiliary drainage channel 3-2. After the auxiliary drainage channel 3-2 is opened, the water in the water container enters the auxiliary drainage channel 3-2 from the overflow chamber 3-3 and is discharged through the auxiliary drainage port 1-2; then, the water level in the water container drops, and after dropping to a predetermined height, the driving gear 6-3 rotates under the action of the return spring 6-2, respectively driving the membrane transmission rod 7 and the piston transmission rod 8 back to their original positions, and then closing the auxiliary drainage channel 3-2 to achieve the overflow prevention function.
