Description

Technical Field

[0001] The utility model relates to the technical field of toilet parts, in particular to a structure for waterproofing a rotating shaft and a toilet water tray operating mechanism. Background Art

[0002] Biodegradable toilets are a new type of toilet that have appeared in recent years. They can degrade human feces through microorganisms. They are particularly suitable for use in indoor environments such as RVs, yachts, and nursing homes for the care of elderly people with limited mobility where it is inconvenient to collect water or discharge waste.

[0003] In order to prevent the culture genes of the biodegradable toilet from being too humid and undergoing anaerobic reactions that produce harmful gases, please refer to the Chinese utility model patent with publication number CN219527847U. A liquid collection tray that can be opened or stored is provided below the excretion channel. When urinating or flushing, the liquid collection tray is located below the excretion channel to collect urine or flushing water and guide it to the urine collection box or sewage tank. When defecating, the liquid collection tray is no longer blocked below the excretion channel, and the excrement falls directly into the biodegradable container below the excretion channel.

[0004] However, in the Chinese utility model patent with publication number CN219527847U, the operating component for driving the liquid collection plate 41 to switch between the first position and the second position includes a first linkage member 42, a second linkage member 43 and a toggle member 44. In order to ensure the smooth rotation of the toggle member 44, no sealing structure is set between the toggle member 44 and the toilet base 10, resulting in the liquid inside the toilet may seep out from the gap between the toggle member 44 and the toilet base 10, affecting the user experience.

[0005] Solving the above problems has become a top priority. Utility Model Content

[0006] In view of this, the utility model provides a structure for waterproofing a rotating shaft and a toilet water tray operating mechanism.

[0007] The technical solution is as follows:

[0008] The first aspect of the present application relates to a structure for waterproofing a rotating shaft, comprising a rotating shaft base and a rotating shaft rotatably inserted into the rotating shaft base, wherein a sealing ring is mounted on the rotating shaft, and the rotating shaft base is composed of a base mounting part and a sealing fitting part. The adjacent end faces of the sealing ring and the sealing fitting part are planar structures that fit each other. Either both of the sealing ring and the sealing fitting part are made of magnetic material, or one of them is made of magnetic material and the other is made of ferromagnetic material, so that the adjacent end faces of the sealing ring and the sealing fitting part attract each other.

[0009] With the above structure for waterproofing the rotating shaft, the mutual attraction between the sealing ring and the sealing fitting is utilized to seal the gap between the rotating part and the fixed part, thereby avoiding water seepage. At the same time, as long as the magnetic attraction force between the sealing ring and the sealing fitting is not too large, it can be ensured that the rotational damping of the magnetic attraction sealing method is much smaller than that of the conventional method using a rubber sealing ring, thus ensuring the smooth rotation of the rotating shaft.

[0010] The second aspect of the present application relates to a toilet water receiving tray operating mechanism, including a toilet main body, a water receiving tray, and the above structure for waterproofing the rotating shaft. The base mounting member is arranged on the toilet main body. The upper end of the rotating shaft is located outside the toilet main body and is fixedly installed with a lever.

[0035] The present utility model will be further described below in conjunction with embodiments and drawings.

[0036] Structural embodiment 1 for waterproofing of the rotating shaft:

[0037] As shown in Figure 1 and Figure 2 A structure for waterproofing a rotating shaft mainly includes a rotating shaft base 4 and a rotating shaft 2 rotatably passing through the rotating shaft base 4, that is: the rotating shaft 2 is installed on the rotating shaft base 4 and can rotate along the rotating shaft base 4.

[0038] Wherein, a sealing ring 3 is sleeved on the rotating shaft 2, the rotating shaft base 4 is assembled by a base mounting member 41 and a sealing fitting member 42, the adjacent end faces of the sealing ring 3 and the sealing fitting member 42 are flat structures that fit each other, one end face of the sealing ring 3 close to the sealing fitting member 42 is a flat structure, one end face of the sealing fitting member 42 close to the sealing ring 3 is a flat structure, and moreover, the adjacent end faces of the sealing ring 3 and the sealing fitting member 42 fit each other.

[0039] Most importantly, among the sealing ring 3 and the sealing fitting member 42, either both are made of magnetic materials, or one is made of magnetic materials and the other is made of ferromagnetic materials, so that the adjacent end faces of the sealing ring 3 and the sealing fitting member 42 attract each other. Magnetic materials refer to a class of substances that can directly or indirectly generate magnetism, and they include but are not limited to iron, cobalt, nickel and many alloys. Ferromagnetic materials refer to materials that exhibit strong magnetism in an externally applied magnetic field, can generate an additional magnetic field in the same direction as the externally applied magnetic field, and can be strongly attracted by a magnet.

[0040] Therefore, in this embodiment, both the sealing ring 3 and the sealing fitting member 42 can be made of magnetic materials, and the adjacent end faces of the sealing ring 3 and the sealing fitting member 42 have opposite polarities to ensure that the adjacent end faces of the sealing ring 3 and the sealing fitting member 42 attract each other. It can also be that one of the sealing ring 3 and the sealing fitting member 42 is made of magnetic materials and the other is made of ferromagnetic materials, as long as it is ensured that the adjacent end faces of the sealing ring 3 and the sealing fitting member 42 can attract each other reliably. Such a design can set the part made of ferromagnetic materials at the position where corrosion resistance is required, thereby improving the service life and sealing reliability.

[0041] Furthermore, the magnetic material in this embodiment is preferably neodymium iron boron or ferrite. If the magnetic material is neodymium iron boron, its magnetic force is very strong. Under normal working conditions, the magnetic force of the neodymium iron boron magnet is very stable, with a high coercivity, and it can achieve a large magnetic force through a small volume, so that the sealing ring 3 and the sealing fitting 42 can be applicable to a narrow installation space; if the magnetic material is ferrite, it has better stability than the neodymium iron boron magnet under temperature and humidity changes, and it is not easy to rust. It should be noted that the magnetic material can also be a common magnet material such as soft magnetic material, as long as it can ensure reliable adsorption between the sealing ring 3 and the sealing fitting 42 and avoid the appearance of gaps.

[0042] Furthermore, the surface of the sealing ring 3 or the sealing fitting 42 made of magnetic material has an anti-corrosion layer, which plays a role in preventing rust and corrosion. Specifically, the anti-corrosion layer can be an antioxidant metal layer such as nickel, zinc, or chromium plated on the surface of the sealing ring 3 or the sealing fitting 42, or a polymer material layer such as epoxy resin that is corrosion-resistant and resistant to rotational friction, or a stainless steel outer wrapping.

[0043] In this embodiment, an installation seat 21 is integrally formed at one end of the rotating shaft 2. A ring-shaped retaining ring 211 protrudes from the end face of the installation seat 21 close to the sealing ring 3. A sealing ring installation groove 22 adapted to the sealing ring 3 is formed between the inner peripheral surface of the ring-shaped retaining ring 211 and the outer peripheral surface of the rotating shaft 2. The sealing ring 3 is fixedly embedded in the sealing ring installation groove 22. The end face of the sealing ring 3 close to the sealing fitting 42 protrudes from or is flush with the end face of the ring-shaped retaining ring 211 close to the sealing fitting 42, so as to ensure the close fit of the sealing ring 3 and the sealing fitting 42 and ensure the sealing performance.

[0044] Furthermore, the maximum diameter of the ring-shaped retaining ring 211 is equal to the maximum diameter of the sealing fitting 42, so that the overall appearance can be better and a better visual effect can be obtained.

[0045] Furthermore, the sealing fitting 42 is sleeved on the base mounting member 41 by an interference fit. And glue is applied at the connection between the sealing fitting 42 and the base mounting member 41. At the same time, glue is also applied at the connection between the sealing ring 3 and the sealing ring installation groove 22, thereby further improving the installation reliability of the sealing ring 3 and the sealing fitting 42.

[0046] Structural Embodiment 2 for Waterproofing of the Rotating Shaft:

[0047] Please refer to Figure 1 、 Figure 3 and Figure 4 , the main structure of this embodiment is exactly the same as that of Structural Embodiment 1 for Waterproofing of the Rotating Shaft, and the difference lies in: the structure of the rotating shaft base 4 is different.

[0048] Specifically, the base mounting member 41 is a first hollow bolt, which includes a first hollow screw portion 411 and a first hollow bolt head 412 integrally formed coaxially at the lower end of the first hollow screw portion 411. The sealing fitting 42 is a first nut threadedly engaged with the first hollow screw portion 411. The first nut is screwed onto the upper end of the first hollow screw portion 411, so that the first nut and the first hollow bolt head 412 can lock the toilet body 1 from the upper and lower sides. The rotating shaft 2 is vertically and rotatably inserted through the first hollow bolt. The upper end surface of the first nut protrudes from or is flush with the upper end surface of the first hollow screw portion 411. Moreover, the first nut has magnetism, and the upper end surface of the first nut is in contact with and attracts the lower end surface of the sealing ring 3.

[0049] Furthermore, for the convenience of installation, the first nut is of a hexagonal nut structure, and the first hollow bolt head 412 is of a disc-shaped structure, which is more suitable for installation in a narrow space. At the same time, a flat slot 412a adapted to a flat-tip screwdriver is formed by recessing the bottom surface of the first hollow bolt head 412, so as to facilitate positioning the first hollow bolt with a flat-tip or cross-tip screwdriver when assembling the first hollow bolt and the first nut.

[0050] Structural Embodiment 3 for Waterproofing of the Rotating Shaft:

[0051] Please refer to Figure 1 、 Figure 5 and Figure 6 , the main structure of this embodiment is completely the same as that of Structural Embodiment 1 for Waterproofing of the Rotating Shaft, and the difference lies in: the structure of the rotating shaft base 4 is different.

[0052] Specifically, the sealing fitting 42 is a second hollow bolt, which includes a second hollow screw portion 421 inserted through the toilet body 1 and a second hollow bolt head 422 integrally formed coaxially at the upper end of the second hollow screw portion 421. The base mounting member 41 is a second nut threadedly engaged with the second hollow screw portion 421. The second nut is screwed onto the lower end of the second hollow screw portion 421, so that the second hollow bolt head 422 and the second nut can lock the toilet body 1 from the upper and lower sides. The rotating shaft 2 is vertically and rotatably inserted through the second hollow bolt. Moreover, the second hollow bolt has magnetism, and the upper end surface of the second hollow bolt head 422 is in contact with and attracts the lower end surface of the sealing ring 3.

[0053] Further, for ease of installation, a screwdriver positioning opening 41a adapted to a flat-head screwdriver is formed by recessing the bottom surface of the second nut, so as to facilitate positioning the first hollow bolt with the flat-head screwdriver when assembling the first hollow bolt and the first nut; meanwhile, a cross screwdriver positioning opening 422a distributed in a cross shape is formed by recessing the upper end surface of the head 422 of the second hollow bolt, so that the second hollow bolt can be screwed into the second nut with a cross screwdriver when the rotating shaft 2 has not been inserted yet.

[0054] Structural Embodiment 4 for Waterproofing of the Rotating Shaft:

[0055] Please refer to Figure 1 and Figure 7 , the main structure of this embodiment is exactly the same as that of Structural Embodiment 1 for waterproofing of the rotating shaft, and the difference lies in that: the upper end of the sealing ring 3 is reduced in diameter to form a sealing ring mounting boss 31 adapted to the sealing ring mounting groove 22, and the sealing ring mounting boss 31 is fixedly embedded in the sealing ring mounting groove 22. Through such a design, the contact area between the sealing ring 3 and the sealing fitting 42 is increased, thereby further improving the sealing performance.

[0056] Further, the maximum diameter of the sealing ring 3 is equal to the maximum diameter of the sealing fitting 42, so that the overall appearance can be better and a better visual effect can be obtained.

[0057] Structural Embodiment 5 for Waterproofing of the Rotating Shaft:

[0058] Please refer to Figure 1 and Figure 8 , the main structure of this embodiment is exactly the same as that of Structural Embodiment 2 for waterproofing of the rotating shaft, and the difference lies in that: the upper end of the sealing ring 3 is reduced in diameter to form a sealing ring mounting boss 31 adapted to the sealing ring mounting groove 22, and the sealing ring mounting boss 31 is fixedly embedded in the sealing ring mounting groove 22. Through such a design, the contact area between the sealing ring 3 and the first nut is increased, thereby further improving the sealing performance.

[0059] Same as Structural Embodiment 4 for waterproofing of the rotating shaft, the maximum diameter of the sealing ring 3 is equal to the maximum diameter of the first nut, so that the overall appearance can be better and a better visual effect can be obtained.

[0060] Structural Embodiment 6 for Waterproofing of the Rotating Shaft:

[0061] Please refer to Figure 1 and Figure 9, the main structure of this embodiment is exactly the same as that of Structural Embodiment 3 for shaft waterproofing. The difference lies in that: the upper end of the sealing ring 3 is reduced in diameter to form a sealing ring mounting boss 31 adapted to the sealing ring mounting groove 22, and the sealing ring mounting boss 31 is fixedly embedded in the sealing ring mounting groove 22. Through such a design, the contact area between the sealing ring 3 and the head 422 of the second hollow bolt is increased, thereby further improving the sealing performance.

[0062] Same as Structural Embodiment 4 for shaft waterproofing, the maximum diameter of the sealing ring 3 is equal to the maximum diameter of the head 422 of the second hollow bolt, so that the overall appearance can be better and a better visual effect can be obtained.

[0063] Toilet water receiving tray operating mechanism Embodiment 1:

[0064] Please refer to Figure 1 、 Figure 2 and Figures 12 - 15 , a toilet water receiving tray operating mechanism, including a toilet main body 1, a water receiving tray 7, and Structural Embodiment 1 or Structural Embodiment 4 for shaft waterproofing. The base mounting member 41 is integrally formed on the outer surface of the toilet main body 1. The upper end of the shaft 2 is located outside the toilet main body 1. Therefore, the mounting seat 21 is integrally formed at the upper end of the shaft 2. At the same time, a lever 5 is fixedly connected to the mounting seat 21 to facilitate controlling the rotation of the shaft 2.

[0065] Correspondingly, the sealing fitting 42 is also located outside the toilet main body 1, and the sealing ring 3 is located directly above the sealing fitting 42.

[0066] The lower end of the shaft 2 is located inside the toilet main body 1, and the lower end of the shaft 2 is connected to the water receiving tray 7 through a connecting component 6, so that by rotating the lever 5, the water receiving tray 7 can move back and forth between a first position directly below the discharge channel 11 of the toilet main body 1 and a second position outside the discharge channel 11.

[0067] Therefore, the above structure can not only effectively prevent the water inside the toilet main body 1 from leaking out through the gap between the shaft 2 and the shaft base 4, playing a good sealing role, but also can easily control the rotation of the shaft through the lever 5, so as to easily and stably adjust the position of the water receiving tray with good smoothness.

[0068] Furthermore, the inner end of the lever 5 is fixedly connected to the mounting seat 21, and the distance between the lever 5 and the toilet main body 1 gradually increases in the direction away from the mounting seat 21, which not only makes the occupation of the external space by the lever 5 as small as possible, making the whole more beautiful, but also is convenient for the user to hold.

[0069] Further, an external thread is provided on the outer peripheral surface of the inner end of the lever 5, and the lever connecting seat 21 has a threaded connection hole 212 that is threadedly engaged with the external thread of the inner end of the lever 5. At the same time, glue is also applied between the two, which not only ensures the reliability of the connection between the lever 5 and the lever connecting seat 21, but also facilitates installation.

[0070] In this embodiment, the connection assembly 6 has two implementation manners:

[0071] Embodiment 1 of the connection assembly 6: Please refer to Figure 10 , the connection assembly 6 includes a connecting rod 61 and a hinge member 62. A connecting member mounting plate 12 is provided in the toilet main body 1. An arc-shaped sliding groove 13 adapted to the hinge member 62 is formed on the connecting member mounting plate 12. The hinge member 62 is slidably mounted in the arc-shaped sliding groove 13. The connecting rod 61 is arranged in the horizontal direction. One end of the connecting rod 61 is synchronously rotatably sleeved on the lower end of the rotating shaft 2. The water receiving tray 7 is hingedly mounted at the other end of the connecting rod 61 through the hinge member 62. Therefore, through the structural design of the arc-shaped sliding groove 13, when the operator rotates the lever 5 back and forth in the horizontal direction, the water receiving tray 7 can be rotated back and forth between a first position directly below the excretion passage 11 of the toilet main body 1 and a second position outside the excretion passage 11.

[0072] Embodiment 2 of the connection assembly 6: Please refer to Figure 11 , the connection assembly 6 includes a connecting rod 61 and a sliding fit rod 62. A connecting member mounting plate 12 is also provided in the toilet main body 1. A mating sliding groove 13 that slidably mates with the sliding fit rod 62 is mounted on the connecting member mounting plate 12. One end of the mating sliding groove 13 close to the water receiving tray 7 penetrates through the connecting member mounting plate 12. At the same time, a linear sliding groove 611 extending along the length direction of the connecting rod 61 is formed on the connecting rod 61. The lower end of the connecting structure 73 of the water receiving tray 7 is hinged with a circular slider 63. The circular slider 63 can not only slide along the linear sliding groove 611, but also rotate in the linear sliding groove 611. At the same time, one end of the sliding fit rod 62 is slidably inserted into the mating sliding groove 13, and the other end is hinged with the connecting structure 73 of the water receiving tray 7.

[0073] When the operator rotates the lever 5 back and forth in the horizontal direction, the water receiving tray 7 can be rotated back and forth between a first position directly below the excretion passage 11 of the toilet main body 1 and a second position outside the excretion passage 11.

[0074] Whether it is Embodiment 1 of the connection assembly 6 or Embodiment 2 of the connection assembly 6, the lower end of the rotating shaft 2 is preferably rotatably connected to the mounting plate 12, which improves the reliability of the installation of the rotating shaft 2.

[0075] The water receiving tray 7 includes a water receiving tray main body 71, a diversion structure 72 communicated with the water receiving tray main body 71, and a connection structure 73 installed on the water receiving tray main body 71. Among them, the diversion structure 72 is used to guide the urine or flushing water collected by the water receiving tray main body 71 to the urine collection box or the sewage box. The connection structure 73 is connected with the connecting rod 61. The water receiving tray main body 71 includes a water receiving tray bottom plate 711 and a water receiving tray side baffle 712 extending upward from the circumferential outer edge of the water receiving tray bottom plate 711, so that the water receiving tray main body 71 can be rotated back and forth between a first position directly below the excretion passage 11 of the toilet main body 1 and a second position outside the excretion passage 11 by rotating the lever 5 back and forth in the horizontal direction.

[0076] During urination or flushing, the water receiving tray main body 71 is located below the excretion passage 11, collects the urine or flushing water and guides it to the urine collection box or the sewage box through the diversion structure 72. During defecation, the water receiving tray main body 71 no longer blocks below the excretion passage 11, and the excrement directly falls into the biodegradation container below the excretion passage 11.

[0077] In this embodiment, the upper edge of the water receiving tray side baffle 712 has a leakage prevention ring 713 extending inward. The leakage prevention ring 713 is a ring-shaped thin plate structure. Therefore, the leakage prevention ring 713 shields the circumferential outer edge of the disk-shaped structure jointly formed by the water receiving tray bottom plate 711 and the water receiving tray side baffle 712, and can effectively prevent splashing water and surging water, avoid the problem of excessive humidity in the biodegradation container, and ensure the stability of the aerobic reaction of the culture medium.

[0078] The diversion structure 72 of this embodiment is a diversion pipe. The diversion pipe is a tubular structure and is not likely to have water leakage such as surging water due to excessive flow, thereby further improving the overall water leakage prevention performance of the toilet water receiving tray. The inlet of the diversion pipe 72 is a liquid discharge port 712a opened on the water receiving tray side baffle 712, and the bottom of the liquid discharge port 712a is lower than or flush with the top surface of the water receiving tray bottom plate 711, so as to better drain the liquid collected in the water receiving tray main body 71 and avoid the problem of odor caused by the inability to completely drain the liquid in the water receiving tray main body 71.

[0079] A sealing ring 8 is sleeved on the lower end of the excretion passage 11. When the water receiving tray main body 71 is located directly below the excretion passage 11, the bottom of the sealing ring 8 is in frictional fit or interference fit with the top surface of the leakage prevention ring 713.

[0080] When the water receiving tray main body 71 is located directly below the discharge channel 11, the bottom of the sealing ring 8 is in frictional fit or interference fit with the top surface of the leak-proof ring 713. By providing the sealing ring 8, when the water receiving tray main body 71 is in the first position directly below the discharge channel 11, the sealing ring 8 can effectively seal the gap between the leak-proof ring 713 and the bottom of the discharge channel 11, ensuring that the liquid falling from the discharge channel 11 can be reliably collected by the water receiving tray main body 71, thereby achieving a better effect of preventing splashing and surging of water.

[0081] Furthermore, the sealing ring 8 includes a sealing ring mounting sleeve 81 sleeved on the lower end of the discharge channel 11. At least one coaxial annular water-blocking thin sheet 82 is integrally formed at the bottom of the sealing ring mounting sleeve 81. The annular water-blocking thin sheets 82 all extend downward. When the water receiving tray main body 71 is located directly below the discharge channel 11, the lower edges of the annular water-blocking thin sheets 82 are in frictional fit with the top surface of the leak-proof ring 713.

[0082] Therefore, by providing the annular water-blocking thin sheets 82 with a thin sheet structure at the bottom of the sealing ring 8 and using the lower edges of the annular water-blocking thin sheets 82 to be in frictional fit with the top surface of the leak-proof ring 713, it can not only effectively seal the gap between the leak-proof ring 713 and the bottom of the discharge channel 11, but also reduce the interference effect, that is, the frictional force, generated by the sealing ring 8 on the rotation of the toilet water receiving tray, thus ensuring the smooth rotation of the toilet water receiving tray.

[0083] It should be noted that one or more circles of annular water-blocking thin sheets 82 can be provided at the bottom of the sealing ring mounting sleeve 81. When multiple circles of annular water-blocking thin sheets 82 are provided, the diameters of the annular water-blocking thin sheets 82 gradually increase, which can ensure an excellent sealing effect and avoid water leakage problems. When only one circle of annular water-blocking thin sheet 82 is provided, the lower edge of the annular water-blocking thin sheet 82 is close to the inner edge of the leak-proof ring 713. Usually, the lower edge of the annular water-blocking thin sheet 82 is 2 mm - 3 mm away from the inner edge of the leak-proof ring 713, which not only ensures the sealing performance and avoids gaps due to improper rotation, but also avoids the problem of the top of the leak-proof ring 713 becoming smelly due to water accumulation.

[0084] Furthermore, the thickness of the lower part of the annular water-blocking thin sheets 82 gradually decreases from top to bottom, so that it can not only achieve a good sealing effect, but also minimize the friction with the leak-proof ring 713 as much as possible, making the rotation of the water receiving tray 7 smoother.

[0085] Moreover, a support flange 83 adapted to the discharge channel 11 is protruded on the inner wall of the sealing ring mounting sleeve 81, and the lower end of the discharge channel 11 is supported on the support flange 83, which not only plays a role in positioning the installation of the sealing ring 8, but also can avoid the problem that the sealing ring 8 cannot achieve a good sealing effect due to upward movement after long-term use.

[0087] The main structure of this embodiment is the same as that of Embodiment 1 of the toilet water receiving tray operating mechanism, and the difference lies in that: the structure of Embodiment 2 for waterproofing the rotating shaft or the structure of Embodiment 5 for waterproofing the rotating shaft is adopted.

[0088] The first hollow screw part 411 is vertically penetrated through the toilet main body 1, and the first nut and the first hollow bolt head 412 are locked on the toilet main body 1 from the upper and lower sides. Therefore, the first nut is located outside the toilet main body 1, and the sealing ring 3 is located directly above the sealing fitting 42.

[0089] Furthermore, in order to ensure the reliability of the connection between the first nut and the first hollow bolt, first elastic washers 91 are provided between the first nut and the toilet main body 1 and between the first hollow bolt head 412 and the toilet main body 1. At the same time, the two first elastic washers 91 can seal the gap between the first hollow bolt and the toilet main body 1.

[0090] Toilet water receiving tray operating mechanism Embodiment 3:

[0091] The main structure of this embodiment is the same as that of Embodiment 1 of the toilet water receiving tray operating mechanism, and the difference lies in that: the structure of Embodiment 3 for waterproofing the rotating shaft or the structure of Embodiment 6 for waterproofing the rotating shaft is adopted.

[0092] The second hollow screw part 421 is vertically penetrated through the toilet main body 1, and the second hollow bolt head 422 and the second nut are locked on the toilet main body 1 from the upper and lower sides. Therefore, the second hollow bolt head 422 is located outside the toilet main body 1, and the sealing ring 3 is located directly above the sealing fitting 42.

[0093] Furthermore, in order to ensure the reliability of the connection between the second nut and the second hollow bolt, second elastic washers 92 are provided between the second nut and the toilet main body 1 and between the second hollow bolt head 422 and the toilet main body 1. At the same time, the two second elastic washers 92 can seal the gap between the first hollow bolt and the toilet main body 1.
