Description

Technical Field

[0001] The invention relates to the field of floor drain cores, and in particular to a telescopic and adjustable straight-discharge anti-odor floor drain core adapted to different fault lengths. Background Art

[0002] The floor drain is an important interface between the drainage pipe system and the indoor floor. As an important component of the drainage system in a house, its performance directly affects the quality of indoor air and is very important for odor control in the bathroom.

[0003] In current decoration, waterproofing will be done on the ground 02 first. There may be several layers of waterproofing according to the needs. After waterproofing, tiles will be laid. This set of construction will raise the ground surface as a whole. When installing the floor drain, the top of the floor drain must be basically flush with the raised ground surface, and the bottom of the floor drain extends to the bottom and connects with the pre-buried sewage pipe 03. This leads to a problem. Since we don't know how much the ground surface will be raised, if the floor drain core 1 is short, the bottom of the floor drain core 1 cannot extend into the sewage pipe 03, and the leaked water will damage the base 01 structure. Figure 1 If the floor drain core 1 is too long, when it encounters a bent drain pipe 03, the bottom of the floor drain core 1 will interfere with the bent portion of the drain pipe 03, making it impossible to install. Figure 2 shown. Summary of the invention

[0004] In order to improve the problem of poor installation adaptability of existing floor drain cores, the present application provides a telescopic and adjustable straight-discharge odor-proof floor drain core that is adaptable to different fault lengths.

[0005] The present application provides a telescopic and adjustable straight-discharge odor-proof floor drain core adapted to different fault lengths, which adopts the following technical solution: A telescopic and adjustable straight-discharge odor-proof floor drain core adapted to different fault lengths, comprising a floor drain core body with a water inlet and a water outlet, the floor drain core body comprising an upper core body and a telescopic core body, the upper core body being slidably connected to the upper part of the telescopic core body, a sealing member being provided between the upper core body and the telescopic core body, the water inlet being located at the top end of the upper core body, the water outlet being located at the bottom end of the telescopic core body, one end of the water outlet being hinged with a sealing plate for sealing the water outlet, and the telescopic core body being provided with a driving member for driving the sealing plate to tightly buckle the water outlet.

[0006] By adopting the above technical solution, when the floor drain core needs to adapt to different thicknesses of the ground or installation environment, the upper core can be slid and adjusted on the telescopic core to change the overall length to adapt to different installation requirements, thereby improving the problem of poor installation adaptability of the existing floor drain core; at the same time, the seal ensures the sealing of the connection to prevent water leakage and odor, and the sealing plate at the water outlet can effectively block when there is no water flow, preventing sewer odor and pests from entering the room.

[0007] Preferably, the telescopic core includes an adjusting core and a lower core, the adjusting core is located between the upper core and the lower core, the bottom end of the adjusting core is connected to the lower core, the upper core is sleeved and movably connected to the top end of the adjusting core, and the water outlet and the driving part are both located on the lower core.

[0008] By adopting the above technical solution, the telescopic core is divided into an adjusting core and a lower core, and the structure is further refined. The lower core has a single function and is only responsible for cooperating with the sealing plate to play a sealing role. The long end adjustment part is completely coordinated by the upper core and the adjusting core. By producing upper cores and adjusting cores of different lengths, adjustments within different length ranges can be performed, which is convenient for production and replacement of parts.

[0009] Preferably, the sealing member is a first sealing ring, a plurality of first convex rings are coaxially provided on the outer wall at the top end of the adjusting core body, a first ring groove is formed between adjacent first convex rings, the first sealing ring is arranged in the first ring groove, the first sealing ring is respectively pressed against the inner wall of the upper core body and the inner wall of the first ring groove, an anti-slip ring is coaxially provided on the inner wall at the bottom end of the upper core body, the anti-slip ring is always located below the first convex ring, and the anti-slip ring is used to limit the first convex ring from detaching from the upper core body from the bottom.

[0010] By adopting the above technical solution, the first sealing ring is arranged in the first ring groove, which can effectively improve the sealing performance. The multiple first convex rings enhance the structural strength and stability and play a limiting role for the first sealing ring. The anti-slip ring limits the first convex ring from detaching from the upper core body from the bottom, avoiding accidental separation of the upper core body and the adjustment core body, thereby ensuring the reliability and safety of the floor drain core during use.

[0011] The locking mechanism is a vertical cam which is provided at the bottom of the two locking plates, and the locking mechanism has a vertical cam which is provided at the bottom of the two locking plates, and a vertical cam which is provided at the bottom of the two locking plates, and a vertical cam is provided at the bottom of the two locking plates, wherein the two locking plates are pivotally connected to each other with a bolt, and the bolt has a round shank to contact the locking mechanism. The two elastic elliptical rings are coaxially fixed on the two hinge shafts of the first handle, and the two elastic elliptical rings are respectively located directly above the two vertical grooves. The elastic block always abuts against the end wall of the movable groove close to the anti-slip ring, and the top of the vertical rod always abuts against the elastic elliptical ring. When the first handle is rotated to abut against the top surface of the upper core body, the long end of the elastic elliptical ring abuts against and blocks the top of the vertical groove, and the two clamping rods extend out of the horizontal groove and clamp the adjusting core body.

[0012] By adopting the above technical scheme, since the water will impact the sealing plate when the floor drain core is draining, it is difficult to keep the adjusting core from relative movement with the upper core for a long time by the friction of the first sealing ring alone when the adjusting core and the upper core are not pulled apart to the limit length position. The design of the locking piece is aimed at the situation that some floor drain cores can be installed, but the sealing plate cannot be fully opened after installation. The relative position of the upper core and the adjusting core can be conveniently locked to ensure that it will not change after the length is adjusted; the adjusting core is clamped or loosened by controlling the clamping rod by turning the first handle, and the operation is simple and convenient; when the elastic elliptical ring rotates to the long end to press against and block the top of the vertical groove, it not only drives the vertical rod, but also fills the gap at the top of the vertical groove, thereby ensuring the cleanliness and stable operation of the internal structure of the floor drain core; the first handle also has the function of removing the entire floor drain core from the installation position, and the setting of the second handle has the function of facilitating the operator to adjust the height position of the adjusting core.

[0013] Preferably, a retaining ring is coaxially provided on the inner wall at the top end of the lower core body, and a retaining groove is opened on the outer wall at the bottom end of the adjusting core body, the retaining ring is clamped in the retaining groove, and a second annular groove is coaxially opened on the outer wall at the bottom end of the adjusting core body, the second annular groove is located directly above the retaining groove, a second sealing ring is provided in the second annular groove, and the second second sealing ring is respectively pressed against the inner wall of the second annular groove and the inner wall of the lower core body.

[0014] By adopting the above technical solution, the cooperation between the clamping ring and the clamping groove realizes a stable connection between the adjusting core and the lower core; the second sealing ring is arranged in the second ring groove, which further ensures the sealing of the connection between the adjusting core and the lower core, prevents water leakage, and extends the service life of the floor drain core.

[0015] Preferably, the water outlet is arranged at an angle, and the sealing plate is hinged at the higher end of the water outlet. When the sealing plate is in a fully closed state, the sealing plate is in the same inclination as the water outlet, and is in a vertical state when the sealing plate is in a fully opened state.

[0016] By adopting the above technical solution, the water outlet is inclined and the sealing plate is in a matching inclined closed state, which is conducive to the smooth discharge of water during drainage. At the same time, when the sealing plate is closed, it can better fit the water outlet to enhance the anti-odor effect; the sealing plate is fully opened in a vertical state, which does not affect the drainage flow.

[0017] Preferably, the driving part includes a power-assisting plate and an elastic reset member for driving the power-assisting plate to press against the bottom of the sealing plate for resetting the sealing plate, the power-assisting plate is hinged at the end with a higher water outlet, and the power-assisting plate presses against the middle position of the bottom of the sealing plate; an installation cavity is provided on the side where the lower core body is hinged to the sealing plate, a side cover is provided on the installation cavity, and the side cover is detachably connected to the lower core body, the elastic reset member and the hinge axis of the power-assisting plate are both located in the side cover, and a resisting portion for limiting the downward rotation angle of the power-assisting plate is extended from the lower end of the side cover, and the resisting surface of the resisting portion is inclined.

[0018] By adopting the above technical scheme, the assisting plate and the elastic reset part in the driving part work together. The elastic reset part can drive the assisting plate to press against the bottom of the sealing plate, provide assistance for the reset of the sealing plate, and ensure that the sealing plate can seal the water outlet tightly in time to effectively prevent odor. The design of the installation cavity and the side cover facilitates the installation and maintenance of components such as the elastic reset part and the assisting plate hinge shaft. The resisting part can limit the downward rotation angle of the assisting plate to ensure the stability and reliability of the driving part.

[0019] Preferably, a driving end extends from the hinge shaft of the assisting plate, and the driving end is located in the side cover. The elastic reset component includes a magnetic component 1 and a magnetic component 2. The magnetic component 1 is arranged at the driving end, and the magnetic component 2 is arranged in the side cover. The magnetic component 2 is located on the side of the magnetic component 1 away from the water outlet. The magnetic component 1 and the magnetic component 2 drive the assisting plate to reset through the repulsive force.

[0020] By adopting the above technical solution, the repulsive force between the magnetic component 1 and the magnetic component 2 is used to drive the assisting plate to reset, which can provide power for the sealing plate to reset more stably and effectively improve the deodorization performance.

[0024] By adopting the above technical scheme, the design of each component of the rotating assembly, such as the first rotating rod, the second rotating rod, the rotating block, the prismatic slot, the sliding groove, etc., realizes remote rotation control. The operator can control the rotation of the magnetic component 2 only by rotating the force block, without affecting the extension and contraction of the upper core and the adjustment core, and the operation is convenient; the cooperation of the limit block and the second arc groove accurately controls the switching of the magnetic component 1 and the magnetic component 2 between the repulsive and attractive states; the design of the metal collision component and the metal block can produce a collision to remind the user when the power-assisting plate is opened.

DETAILED DESCRIPTION

[0043] The following is combined with Figure 3-Figure 16The present application is further described in detail to make the technical solution of the present application easier to understand and grasp.

[0044] The embodiment of the present application discloses a telescopic and adjustable straight-discharge anti-odor floor drain core that is adaptable to different fault lengths. Example

[0045] Reference Figure 1 , refer to Figure 3 and Figure 4 In this embodiment, a telescopic adjustable straight-discharge odor-proof floor drain core adapted to different fault lengths includes a floor drain core 1 with a water inlet 111 and a water outlet 131. The floor drain core 1 includes an upper core 11 and a telescopic core. The upper core 11 is slidably connected to the upper part of the telescopic core. A sealing member is provided between the upper core 11 and the telescopic core. The water inlet 111 is located at the top of the upper core 11, and the water outlet 131 is located at the bottom of the telescopic core. A sealing plate 136 for sealing the water outlet 131 is hinged at one end of the water outlet 131. A driving part 2 for driving the sealing plate 136 to tightly buckle the water outlet 131 is provided on the telescopic core.

[0046] Reference Figure 3 and Figure 4 When the floor drain core 1 needs to adapt to different thicknesses of the ground 02 or installation environments, the upper core 11 can be slid and adjusted on the telescopic core to change the overall length to adapt to different installation requirements, which can improve the problem of poor installation adaptability of the existing floor drain core; at the same time, the seal ensures the sealing of the connection to prevent water leakage and odor. The sealing plate 136 at the water outlet 131 can effectively block when there is no water flow, preventing sewer odor and pests from entering the room.

[0047] Reference Figure 3 and Figure 4 The telescopic core includes an adjusting core 12 and a lower core 13. The adjusting core 12 is located between the upper core 11 and the lower core 13. The bottom end of the adjusting core 12 is connected to the lower core 13. The upper core 11 is sleeved and movably connected to the top of the adjusting core 12. The water outlet 131 and the driving part 2 are both located on the lower core 13.

[0048] Reference Figure 3 and Figure 4 The telescopic core is divided into an adjusting core 12 and a lower core 13, and the structure is further refined. The lower core 13 has a single function and is only responsible for cooperating with the sealing plate 136 to play a sealing role. The long end adjustment part is completely coordinated by the upper core 11 and the adjusting core 12. By producing upper cores 11 and adjusting cores 12 of different lengths, adjustments within different length ranges can be performed, which is convenient for production and replacement of parts.

[0049] Reference Figure 4The sealing member is a first sealing ring 126. A plurality of first convex rings 121 are coaxially provided on the outer wall at the top end of the adjusting core 12. A first annular groove 122 is formed between adjacent first convex rings 121. The first sealing ring 126 is arranged in the first annular groove 122. The first sealing ring 126 respectively presses against the inner wall of the upper core 11 and the inner wall of the first annular groove 122. An anti-slip ring 112 is coaxially provided on the inner wall at the bottom end of the upper core 11. The anti-slip ring 112 is always located below the first convex ring 121. The anti-slip ring 112 is used to limit the first convex ring 121 from detaching from the upper core 11 from the bottom.

[0050] Reference Figure 4 and Figure 5 The first sealing ring 126 is arranged in the first ring groove 122, which can effectively improve the sealing performance. The multiple first convex rings 121 enhance the structural strength and stability, and play a limiting role on the first sealing ring 126; the anti-slip ring 112 limits the first convex ring 121 from separating from the upper core 11 from below, avoiding the accidental separation of the upper core 11 and the adjustment core 12, and ensuring the reliability and safety of the floor drain core during use. When the adjustment core 12 is assembled with the upper core 11, the bottom end of the adjustment core 12 needs to be inserted from the top end of the upper core 11 for assembly.

[0051] Reference Figure 4 and Figure 5 A protrusion 123 is provided on the outer wall of the bottom end of the adjusting core body 12, and an avoidance ring groove 132, a through groove 133 for only the protrusion 123 to pass through, and a first arc groove 134 arranged along the circumferential direction are provided on the inner wall of the top end of the lower core body 13. The upper and lower ends of the through groove 133 are connected to the avoidance ring groove 132 and the middle part of the first arc groove 134 respectively. The protrusion 123 passes through the avoidance ring groove 132 and the through groove 133 in turn to enter the first arc groove 134 and abuts against the end wall of the first arc groove 134.

[0052] Reference Figure 4 and Figure 5 The cooperation of the protrusion 123, the avoidance ring groove 132, the through groove 133 and the first arc groove 134 realizes the quick connection and positioning between the adjustment core 12 and the lower core 13. During installation, it is only necessary to align the protrusion 123 with the through groove 133 and insert it, and then rotate the adjustment core 12 to make the protrusion 123 enter the first arc groove 134. It is easy to operate, the connection is stable, and the installation efficiency is improved.

[0053] Reference Figure 4 and Figure 5 A second annular groove 124 is coaxially opened on the outer wall of the bottom end of the adjusting core 12. When the protrusion 123 enters the first arc groove 134, the second annular groove 124 faces the avoidance annular groove 132. A second sealing ring 125 is provided in the second annular groove 124. The second sealing ring 125 presses against the inner walls of the second annular groove 124 and the inner walls of the avoidance annular groove 132 respectively.

[0054] Reference Figure 4 and Figure 5 The second sealing ring 125 is arranged in the second annular groove 124. After the adjusting core 12 is connected to the lower core 13, the sealing of the connection between the two is further enhanced to prevent sewage leakage, ensure the normal drainage function of the floor drain, and avoid damage to the surrounding environment due to leakage. At the same time, the second sealing ring 125 also limits the relative rotation of the adjusting core 12 and the lower core 13 without artificial external force, which can improve the stability of the connection between the adjusting core 12 and the lower core 13.

[0055] Reference Figure 4 and Figure 5 There are two protrusions 123, which are symmetrically arranged on both sides of the bottom end of the adjusting core 12. There are two through grooves 133 and two first arc grooves 134, respectively. The two through grooves 133 are symmetrically arranged, and the two first arc grooves 134 are symmetrically arranged.

[0056] Reference Figure 4 and Figure 5 The two symmetrically arranged protrusions 123, the through grooves 133 and the first arc grooves 134 make the connection force between the adjusting core 12 and the lower core 13 more uniform, improve the stability and reliability of the connection, better withstand various stresses during use, and extend the service life of the floor drain core.

[0057] Reference Figure 4 and Figure 5 The water outlet 131 is inclined, and the sealing plate 136 is hinged at the higher end of the water outlet 131. When the sealing plate 136 is fully closed, the inclination of the sealing plate 136 is consistent with that of the water outlet 131, and the sealing plate 136 is vertical when it is fully opened.

[0058] Reference Figure 4 and Figure 5 The water outlet 131 is inclined, and the inclination of the sealing plate 136 is consistent with that of the water outlet 131. When the sealing plate 136 is closed, it can fit tightly against the water outlet 131, effectively preventing odor and pests from entering; when the sealing plate 136 is fully opened, it is in a vertical state, which can maximize the drainage channel area, improve drainage efficiency, and reduce the hidden danger of water accumulation.

[0059] Reference Figure 4 and Figure 7 The driving part 2 includes a power-assisting plate 21 and an elastic reset member for driving the power-assisting plate 21 to press against the bottom of the sealing plate 136 for resetting the sealing plate 136 . The power-assisting plate 21 is hinged at the higher end of the water outlet 131 , and the power-assisting plate 21 presses against the middle position of the bottom of the sealing plate 136 .

[0060] Reference Figure 4 and Figure 7, the assisting plate 21 and the elastic reset member are arranged. When the water flow stops, the elastic reset member drives the assisting plate 21 to press against the bottom of the sealing plate 136, helping the sealing plate 136 to quickly reset and tightly seal the water outlet 131 to prevent sewer odor and pests from entering the room. The assisting plate 21 presses against the middle position of the bottom of the sealing plate 136, so that the sealing plate 136 is more evenly stressed and the sealing effect is better.

[0061] Reference Figure 4 and Figure 7 A mounting cavity 3 is provided on one side where the lower core 13 is hinged to the sealing plate 136, and a side cover 31 is provided on the mounting cavity 3. The side cover 31 is detachably connected to the lower core 13, and the hinge axis of the elastic reset member and the power-assisting plate 21 are both located in the side cover 31. A stopper 311 is extended from the lower end of the side cover 31 to limit the downward rotation angle of the power-assisting plate 21.

[0062] Reference Figure 4 and Figure 7 The mounting cavity 3 is used to accommodate the elastic reset member and the hinge shaft of the power-assisting plate 21. The side cover 31 is detachably connected to facilitate the installation, debugging and maintenance of internal components. The blocking portion 311 limits the downward rotation angle of the power-assisting plate 21, ensuring that the power-assisting plate 21 works within a suitable angle range, ensuring the normal opening and closing action and sealing effect of the sealing plate 136.

[0063] Reference Figure 4 and Figure 7 A driving end 211 extends from the hinge shaft of the power-assisting plate 21, and the driving end 211 is located in the side cover 31. The elastic reset member includes a magnetic member 213 and a magnetic member 2 313. Both the magnetic member 1 213 and the magnetic member 2 313 are magnets. The magnetic member 1 213 is arranged at the driving end 211, and the magnetic member 2 313 is arranged in the side cover 31. The magnetic member 2 313 is located on the side of the magnetic member 1 213 away from the water outlet 131. The magnetic member 1 213 and the magnetic member 2 313 drive the power-assisting plate 21 to reset through the repulsive force.

[0064] Reference Figure 4 and Figure 7 The repulsive force between the magnetic member 1 213 and the magnetic member 2 313 is used to drive the assisting plate 21 to reset. The structure is simpler and not easy to be damaged. The magnetic reset has a fast response speed and can help the sealing plate 136 to reset more timely, thereby improving the anti-odor and anti-insect performance of the floor drain.

[0065] Reference Figure 4 and Figure 7The driving end 211 is provided with a first receiving groove 212, and the magnetic member 1 213 is fixedly arranged in the first receiving groove 212. The top of the side cover 31 is provided with a second receiving groove 312, and the second receiving groove 312 is not connected with the installation cavity 3, and the magnetic member 2 313 is arranged in the second receiving groove 312. The side cover 31 is plugged into the lower core 13, and is used to cooperate with the lower core 13 to limit the rotation of the hinge shaft of the power-assisting plate 21. The lower core 13 is also formed with an insert block 135, and the insert block 135 is plugged into the second receiving groove 312, and is used to limit the magnetic member 2 313. The two ends of the sealing plate 136 are respectively hinged to the two ends of the hinge shaft of the power-assisting plate 21. Example

[0066] Reference Figure 7-10 The difference between the second embodiment and the first embodiment is that a locking member 5 for locking the relative position of the upper core 11 and the adjusting core 12 is provided on the upper core 11, a second handle 42 is hinged on the top of the adjusting core 12, the locking member 5 includes two vertical rods 51, two clamping rods 52, two elastic elliptical rings 53 and two elastic blocks 54, two vertical grooves 55 arranged opposite to each other are opened through the top of the upper core 11 in the vertical direction, and a transverse groove 56 is opened along the radial direction of the upper core 11, and one end of the transverse groove 56 passes through the end of the anti-slip ring 112 The other end of the transverse groove 56 extends to communicate with the vertical groove 55, the two vertical rods 51 slide in the two vertical grooves 55 respectively along the vertical direction, the two clamping rods 52 are respectively slidably connected in the two transverse grooves 56 along the length direction of the transverse groove 56, and the bottom end of the vertical rod 51 is inclinedly abutted against the end of the clamping rod 52 close to the corresponding vertical rod 51; the two elastic blocks 54 are respectively fixed on the bottom surfaces of the two clamping rods 52, and the upper core body 11 is respectively provided with movable grooves 57 for the two elastic blocks 54 to move, and the movable grooves 57 connect the transverse groove 56 and the vertical groove 55.

[0067] Reference Figure 7-10 The two elastic elliptical rings 53 are coaxially fixed on the two hinge shafts of the first handle 41, and the two elastic elliptical rings 53 are respectively located directly above the two vertical grooves 55. The elastic block 54 always abuts against the end wall of the movable groove 57 on the side close to the anti-slip ring 112. The top of the vertical rod 51 always abuts against the elastic elliptical ring 53. When the first handle 41 is rotated to abut against the top surface of the upper core body 11, the long end of the elastic elliptical ring 53 abuts against and blocks the top of the vertical groove 55, and the two clamping rods 52 extend out of the horizontal groove 56 and clamp the adjusting core body 12.

[0068] Reference Figure 7-10, because the water will impact the sealing plate 136 when the floor drain core is draining, it is difficult to keep the adjusting core 12 from moving relative to the upper core 11 for a long time by the friction of the first sealing ring 126 when the adjusting core 12 and the upper core 11 are not pulled apart to the limit length position. The design of the locking member 5 is aimed at the situation that some floor drain cores can be installed, but the sealing plate 136 cannot be fully opened after installation. The relative position of the upper core 11 and the adjusting core 12 can be conveniently locked to ensure that it will not change after the length is adjusted; the first handle 41 is turned to control the clamping rod 52 to clamp or release the adjusting core 12, and the operation is simple and convenient.

[0069] Reference Figure 7-10 When the elastic elliptical ring 53 rotates to the long end to press against and block the top of the vertical groove 55, it not only drives the vertical rod 51, but also fills the gap at the top of the vertical groove 55, ensuring the cleanliness and stable operation of the internal structure of the floor drain core.

[0070] Reference Figure 7-10 The second handle 42 is provided to facilitate the operator to adjust the height position of the core body 12 . Example

[0071] Reference Fig.11 and Fig.12 , the difference between the embodiment and the second embodiment is that: the connection method between the lower core 13 and the adjustment core 12 is different, and the installation method of the second magnetic member 313 is different.

In the normal drainage state, the lower core 13 will not be separated from the adjusting core 12. When the lower core 13 needs to be removed from the adjusting core 12, the operator needs to use force to separate the lower core 13 from the adjusting core 12.

[0074] Reference Fig.11 and Fig.12 The setting of the rotating component 7 can drive the second magnetic member 313 to rotate, so as to achieve attraction between the first magnetic member 213 and the second magnetic member 313, thereby increasing the flexibility and functionality of the floor drain.

[0075] Reference Figure 11-13 The rotating assembly 7 includes a first rotating rod 71, a second rotating rod 72 and a rotating block 73. The upper and lower ends of the second magnetic member 313 are respectively provided with prismatic slots 74.

When the limiting blocks 731 respectively abut against the end walls of the second arc groove 76, the magnetic member 1 213 and the magnetic member 2 313 switch between repulsion and attraction.

[0077] Reference Figure 11-13 The first rotating rod 71 is rotated in the upper core body 11 with interference fit, and a force block is fixedly connected to the top of the first rotating rod 71. The force block is located above the upper core body 11 and abuts against the top surface of the upper core body 11. A sliding groove 77 is opened at the bottom end of the first rotating rod 71 in the vertical direction.

[0078] Reference Figure 11-13 The second rotating rod 72 is rotatably connected to the lower core body 13, the bottom end of the second rotating rod 72 extends into the second accommodating groove 312 and is plugged into the prismatic slot 74 above the second magnetic member 313, the top end of the second rotating rod 72 extends into the slide groove 77, and slides in the slide groove 77 along the vertical direction, the second rotating rod 72 rotates synchronously with the first rotating rod 71, and the first rotating rod 71, the second rotating rod 72 and the rotating block 73 are coaxially arranged.

[0079] Reference Fig.12 , Fig.13 and Fig.15The abutting surface of the resisting portion 311 is inclined. The abutting surface of the resisting portion 311 is covered with a buffer pad 84, an extension rod 81 is inserted at the bottom end of the rotating block 73, and the extension rod 81 rotates with the rotating block 73 and is connected to the side cover 31. A metal collision piece 82 is provided on the side wall of the bottom end of the extension rod 81, and a first avoidance opening 85 for the bottom end of the extension rod 81 and the metal collision piece 82 to move is provided on the buffer pad 84, and a second avoidance opening 86 for the metal collision piece 82 to move is provided on the side cover 31. A metal block 83 is provided on the side surface of the power assisting plate 21 abutting against the resisting portion 311. When the rotating block 73 rotates to the point where the magnetic piece 1 213 and the magnetic piece 2 313 repel each other, the metal collision piece 82 is located in the second avoidance opening 86; when the rotating block 73 rotates to the point where the magnetic piece 1 213 and the magnetic piece 2 313 attract each other, the metal collision piece 82 extends out of the first avoidance opening 85 and collides with the metal block 83 on the power assisting plate 21.

[0080] Reference Figure 11-Figure 16 The design of each component of the rotating assembly 7, such as the first rotating rod 71, the second rotating rod 72, the rotating block 73, the prismatic slot 74, the sliding groove 77, etc., realizes remote rotation control. The operator can control the rotation of the magnetic part 2 313 only by rotating the force block, without affecting the extension and contraction of the upper core 11 and the adjustment core 12, and the operation is convenient; the cooperation of the limit block 731 and the second arc groove 76 accurately controls the switching of the magnetic part 1 213 and the magnetic part 2 313 between the repulsive and attractive states; the design of the metal collision part 82 and the metal block 83 can produce a collision to remind the user when the power-assisting plate 21 is opened. The power-assisting plate 21 is in a fully open state at this time. At the same time, the setting of the buffer pad 84 and the avoidance opening protects the components without affecting their normal operation.

[0081] Reference Figure 11-Figure 16 The rotation connection method of the first rotating rod 71, the second rotating rod 72 and the rotating block 73 can be installed by common means. If necessary, various auxiliary blocks that limit the rotation axis can be set on the first rotating rod 71, the second rotating rod 72 and the rotating block 73.

[0082] Reference Fig.15 and Fig.16 The metal collision piece 82 can be any metal piece with a certain strength that can collide crisply with the metal block 83. Since the household sewage pipe 03 is usually made of plastic, the collision sound between the sealing plate and the sewage pipe 03 is completely different from the collision sound between the metal block 83 and the metal collision piece 82, so the operator can judge whether the sealing plate is fully opened by the sound; at the same time, when the magnetic piece 1 213 and the magnetic piece 2 313 repel each other.
