[0021] Specifically, the floor drain 1 and the floor drain cover 2 are both configured as a box-shaped structure, the upper end of the floor drain 1 (the end of the floor drain 1 located on the positive direction of the Z axis) is the opening end of the floor drain 1, the lower end of the floor drain cover 2 (the end of the floor drain cover 2 located on the negative direction of the Z axis) is the opening end of the floor drain cover 2, the opening end of the floor drain cover 2 is connected to the opening end of the floor drain 1, the floor drain cover 2 is partially accommodated in the floor drain 1, and the floor drain cover 2 can move up and down in the floor drain 1 along the vertical direction. A first grid is provided on the top plate of the floor drain cover 2, and the first grid is connected to the floor drain 1. A second grid is provided on the bottom plate 11 of the floor drain 1. The structures of the first grid and the second grid can be completely the same. The bottom plate 11 of the floor drain 1 is installed on the top of the sewage pipe 9. The bottom plate 11 is connected to the sewage pipe 9 through the second grid. The bottom end of the sewage pipe 9 is used to discharge sewage; the control unit 5 and the pressure sensor 6 are both installed at the end of the bottom plate 11 away from the sewage pipe 9, that is, the upper end of the bottom plate 11. The control unit 5 and the pressure sensor 6 are connected in communication, and the pressure sensor 6 is used to detect water pressure; the bypass pipe 7 is vertical, and the bottom end of the bypass pipe 7 is connected to the sewage pipe 9. The top end of the bypass pipe 7 extends to the top of the bottom plate 11 and is provided with a water inlet 71 (see below for details) ), the water inlet 71 is used for sewage to flow into the bypass pipe 7; the fixed end of the telescopic column 3 is connected to the bottom plate 11 by screws, the movable end of the telescopic column 3 is connected to the floor drain cover 2 by screw drive, and the telescopic column 3 is connected to the control unit 5 in communication; the floor drain 1 includes a first side wall 12, the first side wall 12 is provided with an opening, one end of the side passage 8 is connected to the first side wall 12, and is connected to the floor drain 1 through the opening, and the other end of the side passage 8 extends downward and is connected to the sewage pipe 9; the impeller 4 is located directly below the bypass pipe 7, and is installed on the inner wall of the sewage pipe 9 by rotating the shaft, and the end of the shaft away from the impeller 4 is connected to the trigger switch of the control unit 5 (the trigger switch can be triggered by the rotation of the shaft, without specific restrictions). The anti-blocking floor drain based on water pressure information self-starting in this embodiment includes at least the following situations: Case 1: If Figure 4 and Figure 7 As shown, when the floor drain 1 is used normally, that is, the floor drain 1 is not blocked, the sewage flowing out of the second grille of the floor drain 1 for the first time causes the rotor 4 to rotate, and the rotation of the rotor 4 triggers the control unit 5, and the control unit 5 starts the pressure sensor 6; when no sewage flows out of the second grille of the floor drain 1, the rotor 4 does not rotate, and the control unit 5 and the pressure sensor 6 do not start; when the second grille of the floor drain 1 flows out sewage for the second time, the rotor 4 rotates again, and the control unit 5 and the pressure sensor 6 are restarted, that is, only when the rotor 4 rotates, the control unit 5 and the pressure sensor 6 will be started successively, thereby avoiding the waste of electricity caused by the continuous operation of the control unit 5 and the pressure sensor 6 when no sewage flows out.

[0022] Case 2: When the amount of water is too large in a short period of time, water flows out of the bypass pipe 7 and the second grille of the floor drain 1 at the same time, and the runner 4 will also rotate; when the amount of water is small and water only flows out from the second grille of the floor drain 1, the runner 4 will also rotate; when no water flows out, the runner 4 will not rotate.

[0023] Case 3: If Figure 1 , Figure 3 and Figure 5 As shown, the floor drain 1 is blocked during use. For example, before the floor drain 1 is blocked, sewage flows out of the second grille of the floor drain 1, the wheel 4 rotates, the control unit 5 starts, the control unit 5 starts the pressure sensor 6, and the pressure sensor 6 detects the current sewage pressure; when the floor drain 1 is gradually blocked, the sewage will gather on the floor drain 1 and flow out from the bottom of the bypass pipe 7, so that the wheel 4 rotates, and the sewage pressure detected by the pressure sensor 6 gradually increases. When the sewage pressure increases to a certain threshold (the second grille of the floor drain 1 is completely blocked at this time), the pressure sensor 6 feeds back a signal to the control unit 5, and the control unit 5 controls the telescopic column 3 (the telescopic column 3 can be understood as a gas spring) to start, and the telescopic column 3 drives the floor drain cover 2 to move upward, so that the floor drain cover 2 protrudes from the ground, the opening on the first side wall 12 is opened, and the side pipe 8 is connected to the floor drain 1, and the sewage is discharged into the sewage pipe 9 through the side pipe 8. And because the floor drain 1 cover rises, it can remind people that the floor drain 1 is blocked and can be cleaned after washing.

[0024] Therefore, in the present embodiment, when the floor drain 1 is not blocked, the sewage flows into the floor drain 1 through the first grille on the floor drain cover 2, and flows into the sewage pipe 9 only from the second grille on the bottom plate 11 of the floor drain 1, and is discharged through the sewage pipe 9; when the floor drain 1 is blocked, the sewage flows out from the bypass pipe 7, and the sewage flowing out of the bypass pipe 7 realizes the rotation of the runner 4, and the runner 4 can drive the rotating shaft to rotate, and then realize the start of the control unit 5 by the rotation of the rotating shaft. The mode of realizing the start of the control unit 5 by the rotation of the runner 4 can effectively avoid the waste of energy caused by the long-term operation of the control unit 5. The control unit 5 can start the pressure sensor 6, the pressure sensor 6 can detect the sewage pressure in the floor drain 1, and feed back the detected pressure to the control unit 5. The control unit 5 can start the telescopic column 3 according to the detection result of the pressure sensor 6, and the telescopic column 3 can lift the floor drain cover 2. The floor drain cover 2 opens the opening on the first side wall 12, and the sewage in the floor drain 1 can flow into the sewage pipe 9 through the side passage 8. At the same time, after the floor drain cover 2 is lifted, the floor drain cover 2 protrudes from the ground, so that the sewage can be discharged in time and the user can be reminded in time, thereby improving the user experience of the floor drain 1.

[0025] Optionally, combined Figure 1As shown, the bypass pipe 7 includes an open end and a sealed end. The open end is connected to the sewage pipe 9, and the sealed end extends to the top of the bottom plate 11. A water inlet 71 is provided on the side wall of the bypass pipe 7 near the sealed end. The water inlet 71 is connected to the bypass pipe 7 and is used for sewage to flow in.

[0026] Specifically, the open end of the bypass pipe 7 refers to the lower end of the bypass pipe 7, and the sealed end of the bypass pipe 7 refers to the upper end of the bypass pipe 7. A water inlet 71 is provided on the side wall of the bypass pipe 7 close to the sealed end. The water inlet 71 is connected to the bypass pipe 7, and the sewage flows into the bypass pipe 7 from the water inlet 71 on the side wall.

[0027] In this way, the open end is installed on the bottom plate 11 and connected with the sewage pipe 9, the sealed end extends to the top of the bottom plate 11, and a water inlet 71 is provided on the side wall of the bypass pipe 7 near the sealed end, the water inlet 71 is connected with the bypass pipe 7, and the sewage can flow into the bypass pipe 7 through the water inlet 71 on the side wall. In this way, it can be avoided that impurities in the sewage passing through the floor drain cover 2 directly enter the bypass pipe 7 from the upper end of the bypass pipe 7 to cause blockage of the bypass pipe 7.

[0028] Optionally, combined Figure 1 As shown, the runner 4 is located above the outlet end of the side passage 8 .

[0029] Specifically, the outlet end of the side passage 8 refers to the end of the side passage 8 located in the negative direction of the Z axis, that is, the bottom end of the side passage 8. The sewage flows from top to bottom, and the greater the distance between the impeller 4 and the second grid of the floor drain 1, the greater the impact load of the sewage on the impeller 4.

[0030] In this way, by locating the impeller 4 above the outlet end of the side passage 8 , the installation position of the impeller 4 is relatively high, thereby reducing the impact load on the impeller 4 when the sewage flows downward, thereby extending the service life of the impeller 4 .

[0031] Optionally, a protective cover is provided on the bottom plate 11 , and the protective cover covers the pressure sensor 6 .

[0032] Specifically, the protective cover covers the pressure sensor 6 and can be installed on the bottom plate 11 of the floor drain 1 by screws.

[0033] In this way, the pressure sensor 6 is covered by the protective cover, which prevents the falling sewage from directly contacting the sensor 6 and causing the pressure sensor 6 to generate a pressure error, thereby improving the accuracy of the pressure sensor 6.

[0034] Optionally, combined Figure 2 and Figure 3 As shown, a third grille 21 is further provided on the circumferential side wall of the floor drain cover 2 , wherein the third grille 21 provided on the second side wall is located above the opening of the first side wall 12 .

[0035] Specifically, the second side wall of the floor drain cover 2 refers to the side wall of the floor drain cover 2 located in the positive direction of the X axis, and a third grid 21 is provided on the second side wall of the floor drain cover 2. The third grid 21 is located at one end of the second side wall of the floor drain cover 2 facing the positive direction of the Z axis, that is, the third grid 21 is located at the upper part of the second side wall of the floor drain cover 2, and the lower part of the second side wall of the floor drain cover 2 is a solid structure, such as Figure 3 and Figure 5 As shown, the anti-blocking floor drain based on water pressure information self-starting in this embodiment also includes situation 4: when the floor drain 1 has been blocked, but the floor drain cover 2 is not lifted, and when people take a bath, the sewage generated accumulates on the floor drain 1, and after reaching a certain height, it enters the runner 4 through the bypass pipe 7, driving the rotation of the runner 4, repeating the process of situation 3, and at the same time, the sewage can also enter the sewage pipe 9 through the side pipe 8 through the third grid 21, and be discharged from the sewage pipe 9, so as to initially alleviate the water blockage. When the floor drain cover 2 is lifted, the third grid 21 can be used as a new channel for sewage to enter the floor drain 1, and at the same time, the lower half of the side wall opens the opening of the side pipe 8, and the sewage in the floor drain 1 can be discharged from the bypass pipe 7.

[0036] In this way, a third grille 21 is also provided on the second side wall of the floor drain cover 2. The third grille 21 is located at one end of the second side wall away from the bottom plate 11. The third grille 21 can alleviate the sewage blockage in the early stage of blockage of the floor drain 1, and can also form a new sewage channel after the floor drain cover 2 is lifted to improve the sewage discharge efficiency.

[0037] In some embodiments, the water inlet 71 at the top of the bypass pipe 7 is flush with or slightly lower than the bottom of the third grid 21. The purpose of this arrangement is to ensure that the third grid 21 can relieve blockage in the early stage of blockage, and to ensure that sewage can flow into the bypass pipe 7 through the water inlet 71 to ensure sewage discharge efficiency.

[0038] Based on the above embodiments, the anti-blocking floor drain operation method in the embodiments of the present invention is also applicable to at least the following situations: Case 4: Taking bathing as an example, after the first bathing, the floor drain 1 is blocked and the amount of sewage is small. The sewage neither flows out from the second grille of the floor drain 1 nor flows out from the bypass pipe 7, that is, the pressure sensor 6 does not detect the water pressure. In the second bathing room, after the sewage accumulates to a certain height on the floor drain 1, the sewage can flow out from the bypass pipe 7. At this time, some sewage will also flow into the side pipe 8 from the third grille 21 and be discharged from the sewage pipe 9. However, the drainage effect is poorer than the drainage effect of the floor drain cover 2 lifted by the telescopic column 3. Therefore, based on this special situation, the setting of the bypass pipe 7 can ensure that the runner 4 can rotate, thereby ensuring the reliability of the water pressure detection of the pressure sensor 6.

[0039] Optionally, the impeller 4 includes a sleeve and a plurality of blades distributed around the central axis of the sleeve, adjacent blades are spaced apart, a plurality of blades are connected to the sleeve at one end close to the sleeve, the sleeve is fixedly connected to the rotating shaft, and sewage flowing out from the bottom of the bypass pipe 7 is used to impact the blades so that the blades drive the sleeve to rotate.

[0040] Specifically, the sleeve is sleeved on one axial end of the rotating shaft mentioned above, and the number of blades is set to four. The four blades are evenly distributed around the sleeve, each blade is perpendicular to the axis of the sleeve, and each blade is fixed on the sleeve at one end facing the sleeve. After the sewage falls between two adjacent blades, the impact of the sewage can exert circumferential force on the blades, thereby driving the blades to rotate continuously. In this way, by setting the adjacent blades at intervals, a plurality of blades are connected to the sleeve near one end of the sleeve, and the sleeve is fixedly connected to the rotating shaft. The sewage flowing out from the bottom of the bypass pipe 7 is used to impact the blades, so that the blades drive the sleeve to rotate. On the basis of realizing that the sewage drives the impeller 4 to rotate, the lightweight design of the impeller 4 is realized to reduce the weight of the impeller 4, thereby reducing the external load of the rotating shaft and extending the service life of the rotating shaft.

[0041] Combination Figure 8 As shown, another embodiment of the present invention further provides an anti-blocking floor drain operation method, based on the anti-blocking floor drain self-starting based on water pressure information as described above, comprising: When the rotating wheel 4 rotates to trigger the control unit 5 and the pressure sensor 6 to operate, the pressure sensor 6 detects the water pressure twice within a first preset time period; If the water pressure values ​​measured twice are both greater than the first threshold, the control unit 5 drives the telescopic column 3 to start, so that the telescopic column 3 drives the floor drain cover 2 to move away from the floor drain 1, and opens the opening on the first side wall 12 of the floor drain 1; If the value of the water pressure measured for the first time is greater than the first threshold value, and the value of the water pressure measured for the second time is less than the first threshold value, the control unit 5 does not drive the telescopic column 3 to start.

[0042] Specifically, the anti-blocking floor drain operation method in the embodiment of the present invention is applicable to at least the following situations: Situation 1: During the use of the floor drain 1, sewage passes through the floor drain 1 and causes the rotating wheel 4 to rotate. After the rotating wheel 4 rotates, the control unit 5 runs, and the control unit 5 controls the pressure sensor 6 to run. The pressure sensor 6 detects the first pressure, and after the first preset time period, the pressure sensor 6 detects the second pressure again. When the floor drain is blocked, the first pressure and the second pressure are both greater than the preset first threshold value, and the control unit 5 drives the telescopic column 3 to start, so that the telescopic column 3 drives the floor drain cover 2 to move away from the floor drain 1, and the opening on the first side wall 12 of the floor drain 1 is opened, and the side passage 8 is opened, and the sewage generated is discharged into the sewage pipe 9 through the side passage 8, so that the floor drain 1 can still be used normally. Due to the rise of the floor drain cover 2, people can be reminded that the floor drain 1 has been blocked and can be cleaned after washing. At this time, the bypass pipe 7 and the side passage 8 will also drain water to alleviate the water accumulation in the room.

[0043] Case 2: When the floor drain 1 is not blocked, but the amount of water generated on the ground in a short period of time is too large, the drainage of the floor drain 1 is not enough to drain the water in time, and the sewage is discharged downward through the floor drain 1 and the water inlet 71 of the bypass pipe 7, thereby causing the wheel 4 to rotate. After the wheel 4 rotates, the control unit 5 runs, and the control unit 5 controls the pressure sensor 6 to run. The pressure sensor 6 detects a first pressure, and since the excessive amount of water occurs in a short period of time, as time goes by, the floor drain 1 discharges the water. The water pressure detected again by the pressure sensor 6 after an interval of the first preset time period (usually understood as the water pressure is zero) will be less than the preset first threshold value, thereby avoiding the misjudgment of the blockage of the floor drain 1, and thus avoiding the ineffective lifting of the floor drain cover 2.

[0044] For example, the first threshold is set to 10MPA, the first preset time period is 5S, after the pressure sensor 6 is started, the water pressure value detected for the first time is 11MPA, and after an interval of 5S, the water pressure value detected for the second time is 12MPA, the water pressure continues to increase, and the control unit 5 drives the telescopic column 3 to start, and the telescopic column 3 lifts the floor drain cover 2; after the pressure sensor 6 is started, the water pressure value detected for the first time is 11MPA, and after an interval of 5S, the water pressure value detected for the second time is 8MPA, the water pressure continues to decrease, and the control unit 5 does not start the telescopic column 3.

[0045] In this way, when the wheel 4 rotates and the control unit 5 and the pressure sensor 6 are running, the pressure sensor 6 detects the water pressure twice within the first preset time period. If the water pressure values ​​measured twice are both greater than the first threshold, the control unit 5 drives the telescopic column 3 to start, so that the telescopic column 3 drives the floor drain cover 2 to move away from the floor drain 1 and opens the opening on the first side wall 12 of the floor drain 1; the water pressure detected twice by the pressure sensor 6 within the first preset time period is greater than the first threshold, so that the floor drain cover 2 is lifted up by the telescopic column 3 in time, and the sewage is discharged in time; when the wheel 4 rotates and the control unit 5 and the pressure sensor 6 are running, the pressure sensor 6 detects the water pressure twice within the first preset time period. If the value of the first water pressure is greater than the first threshold and the value of the second water pressure is less than the first threshold, the control unit 5 does not drive the telescopic column 3 to start, which can avoid the misjudgment of the blockage of the floor drain 1 and avoid the ineffective lifting of the floor drain cover 2.

[0046] Optionally, the anti-blocking floor drain operation method further includes: After a first set period of time when the rotating wheel 4 starts to rotate, the pressure sensor 6 starts to be activated.

[0047] Specifically, the delayed start of the pressure sensor 6 means that after the wheel 4 rotates, the control unit 5 starts the pressure sensor 6 after a first set time period to reduce the waste of energy of the pressure sensor 6. For example, the amount of water is large in a short period of time, and the bypass pipe 7 and the floor drain 1 discharge the water into the sewage pipe 9 at the same time. Since the amount of water in the floor drain 1 is gradually reduced, if the pressure sensor 6 is started in time, it is possible that the water pressure value in the floor drain 1 detected by the pressure sensor 6 is greater than the first threshold value, but in fact the floor drain 1 is not blocked, which makes the pressure sensor 6 invalid to start, resulting in energy waste.

[0048] In this way, by starting the pressure sensor 6 after the first set time period when the rotating wheel 4 starts to rotate, it is possible to avoid wasting energy due to ineffective starting of the pressure sensor 6.

[0049] Optionally, the anti-blocking floor drain operation method further includes: After the second set period of time during which the wheel 4 stops rotating, the control unit 5 and the pressure sensor 6 are turned off.

[0050] Specifically, the delayed closing of the control unit 5 and the pressure sensor 6 means that when the rotating wheel 4 enters the stationary state from the rotating state, the control unit 5 and the pressure sensor 6 are closed after the second set time period, so as to ensure the timeliness of the control unit 5 and the pressure sensor 6. For example, when the rotating wheel 4 fails to rotate, the rotating wheel 4 stops rotating. Within the second set time period, the control unit 5 and the pressure sensor 6 can still maintain the working state, and the pressure sensor 6 can still detect the water pressure. The control unit 5 can still drive the telescopic column 3 to start after the rotating wheel 4 stops rotating, so as to lift the floor drain cover 2 and remind people that the floor drain 1 is blocked.

[0051] In this way, by turning off the control unit 5 and the pressure sensor 6 after the second set time period when the wheel 4 stops rotating, the control unit 5 and the pressure sensor 6 can remain in working condition after the wheel 4 stops rotating, thereby ensuring the timeliness of the control unit 5 and the pressure sensor 6 and improving the scope of application of the control unit 5 and the pressure sensor 6.

[0052] Optionally, the anti-blocking floor drain operation method further includes: When the rotating wheel 4 does not rotate and the pressure value detected by the pressure sensor 6 is greater than the first threshold, the control unit 5 drives the telescopic column 3 to start, so that the telescopic column 3 drives the floor drain cover 2 to move away from the floor drain 1 and opens the opening on the first side wall 12 of the floor drain 1.

[0053] Specifically, in combination with the foregoing, when hair is already stored on the floor drain 1 but a small amount of sewage can still pass through, if sewage enters the floor drain 1, the floor drain 1 can still discharge the sewage, but the drainage capacity is poorer than that of the floor drain 1 not being blocked, and the rotor 4 can rotate. However, when the floor drain 1 is completely blocked and the amount of sewage is not large, the water temporarily stored on the floor drain 1 is not enough to be discharged through the bypass pipe 7, which is equivalent to that when the rotor 4 rotates, since no sewage flows out of the bypass pipe 7, the rotor 4 will no longer rotate, and the control unit 5 and the pressure sensor 6 are set to delayed closing. After the rotor 4 stops rotating, when the pressure value detected by the pressure sensor 6 is greater than the first threshold value, the control unit 5 drives the telescopic column 3 to start, so that the telescopic column 3 drives the floor drain cover 2 to move away from the floor drain 1, and opens the opening on the first side wall 12 of the floor drain 1. After the rotor 4 stops rotating, the pressure value detected by the pressure sensor 6 is greater than the first threshold value, and the blockage condition of the floor drain 1 can be judged again to improve the scope of application.

[0054] Optionally, the anti-blocking floor drain operation method further includes: After the telescopic column 3 lifts up the floor drain cover 2, the floor drain cover 2 is manually reset.

[0055] Specifically, manually resetting the floor drain cover 2 means that the user can input a reset command to the control unit 5 (for example, resetting the control unit 5 through the controller of the control unit 5). After receiving the reset command, the control unit 5 drives the telescopic column 3 to retract, and then manually presses the floor drain cover 2 into the floor drain 1 for next use.

[0056] In this way, after the telescopic column 3 lifts up the floor drain cover 2, the floor drain cover 2 can be manually reset and reused to save the use cost.

[0057] Although the present invention is disclosed as above, the protection scope of the present invention is not limited thereto. Those skilled in the art may make various changes and modifications without departing from the spirit and scope of the present invention, and these changes and modifications will fall within the protection scope of the present invention.
