[0049] To provide a clearer understanding of the technical features, objectives, and effects of the present invention, specific embodiments of the present invention will now be described with reference to the accompanying drawings.

[0050] like Figures 1 to 15 As shown, this embodiment provides a toilet seat assembly for use in a toilet. The toilet seat assembly includes a cover 1 and a seat ring 2. A cover 14 is provided on the back of the cover 1, spaced apart from the surface of the cover 1. The gap between the cover 14 and the cover 1 forms a cavity 15. The surface area of ​​the cover 14 is smaller than that of the cover 1. An annular opening is formed between the outer periphery of the cover 14 and the outer periphery of the cover 1. A functional component is also provided on the back of the cover 1. When the seat ring 2 and the cover 1 are closed, the seat ring 2 can block the annular opening, and the functional component can perform functional operations on the seat ring 2 and the cover 1.

[0051] In use, the cover plate assembly is installed on the toilet bowl body 9, and when the seat 2 is covered on the back of the cover 1, the functional components can perform functional operations to simultaneously perform corresponding functional operations on the front of the seat 2 and the back of the cover 1. The functional components include, but are not limited to, sterilization components, cleaning components, and / or drying components, etc., to perform corresponding sterilization (or disinfection), cleaning, and / or drying, etc. functional operations on the seat 2 and the cover 1; for example, when the functional components use ultraviolet sterilization, steam sterilization, sterilization agent sterilization, etc. sterilization components, sterilization operations can be performed.

[0052] Therefore, in the cover plate assembly of the present embodiment, the cavity 15 is formed between the back of the cover 1 and the cover 14, and the seat 2 can block the annular opening when the seat 2 is covered on the cover 1, which can effectively reduce or avoid injury to the user during functional operation; since the volume of the cavity 15 is relatively small, good sterilization and other functional effects can be achieved in a very short time, the functional operation efficiency is higher, and the seat 2 and the cover 1 can be simultaneously subjected to functional action. In addition, functional operation does not necessarily require that the toilet is not used, for example, when the seat 2 is not used, the cover 1 and the seat 2 are both in the open position, at this time the user can perform functional operation while using the toilet (generally for men to urinate), reducing the waiting time of the user.

[0053] In a specific implementation, the functional components include a fluid conduit 3, the first end of the fluid conduit 3 extends into the cavity 15, and the second end of the fluid conduit 3 is located outside the cover 1 (the second end of the fluid conduit 3 can be connected with an external functional fluid storage device), and the fluid conduit 3 can be used to inject functional fluid medium into the cavity 15.

[0054] The fluid conduit 3 is mainly suitable for functional operation using gas or liquid fluid medium, for example, the functional fluid medium in the present embodiment can include, but is not limited to, steam, air, sterilization agent or clean water, when steam or sterilization agent is injected into the cavity 15, sterilization or disinfection function can be achieved on the seat 2 and the cover 1; when air is injected into the cavity 15, drying function can be achieved on the seat 2 and the cover 1; when clean water is injected into the cavity 15, cleaning function can be achieved on the seat 2 and the cover 1.

[0055] When the fluid conduit 3 is used to inject functional fluid medium into the cavity 15, the functional fluid medium is always in a flowing state and can fill the cavity 15, the front of the seat 2 and the back of the cover 1 can be in full contact with the functional fluid medium, which effectively improves the sterilization and other functional effects; at the same time, since the volume of the cavity 15 is very small, the best functional effect can be achieved in a short time, and the amount of steam and other functional fluid medium used is relatively small.

[0056] Preferably, in order to allow the functional fluid medium to be injected more uniformly and quickly into all parts of the cavity 15, such as Figures 1 to 7 As shown, a spray arm 4 with a spray chamber 41 is provided at the first end of the fluid pipe 3. The spray chamber 41 is connected to the fluid pipe 3. The spray arm 4 is provided with a nozzle 42. The nozzle 42 can drive the spray arm 4 to rotate automatically in a circumferential direction under the reaction force of the spray of the functional fluid medium. The spray arm 4 can be used to concentrate the spray of the functional fluid medium, so as to spray the functional fluid medium into the cavity 15 faster and more evenly, thereby enhancing the sterilization and other functional effects; for example, when spraying the sterilization medium, the sterilization effect can be enhanced; it can also spray hot air to dry and heat the surface of the seat ring 2.

[0057] For ease of processing and installation, a fixing ring 32 is formed at the first end of the fluid pipe 3, and a fixing shaft 1411 is provided on the cover 14. A rotating cylinder 5 is provided between the fixing ring 32 and the fixing shaft 1411. The first end of the rotating cylinder 5 is fixedly connected to the fixing ring 32, and the second end of the rotating cylinder 5 is sleeved on the fixing shaft 1411. Multiple radial openings 51 are provided on the side wall of the rotating cylinder 5, and the radial openings 51 communicate with the fluid pipe 3. A mounting hole 43 is provided in the middle of the spray arm 4, and the spray arm 4 is rotatably sleeved on the outside of the rotating cylinder 5 through the mounting hole 43. Each radial opening 51 communicates with the spray chamber 41. The first end of the fluid pipe 3 is provided with a first limiting part that can limit the spray arm 4, and the rotating cylinder 5 is provided with a second limiting part that can limit the spray arm 4.

[0058] The fluid conduit 3 is generally arranged axially along the length of the cover 1. The fluid conduit 3 can be tightly attached to the back of the cover 1 and fixedly connected to the cover 1 by fasteners. An annular extension plate 31 is formed at the first end of the fluid conduit 3. The surface of the extension plate 31 is approximately parallel to the axis of the fluid conduit 3, and the extension plate 31 constitutes the first limiting part. A fixing ring 32 is coaxially fixed on the extension plate 31. The fixing ring 32, the rotating cylinder 5, and the fixing shaft 1411 are coaxially arranged, and their axial directions are approximately perpendicular to the axis of the fluid conduit 3. An annular limiting plate 52 protrudes outward from the middle of the rotating cylinder 5, and the limiting plate 52 constitutes the second limiting part. The spray arm 4 can be axially limited between the extension plate 31 and the limiting plate 52. A first protruding ring 44 extends from the mounting hole 43 on the first surface of the spray arm 4 facing the cover 1, and a second protruding ring 45 extends from the mounting hole 43 on the second surface of the spray arm 4 facing the cover 14 (the second surface is arranged opposite to the first surface). The first protruding ring 44 and the second protruding ring 45 are both coaxially arranged with the mounting hole 43 and the rotating cylinder 5, and the first protruding ring 44 and the second protruding ring 45 are both sleeved on the outside of the rotating cylinder 5. The extension plate 31 can axially limit the end of the first protruding ring 44, and the limiting plate 52 can axially limit the end of the second protruding ring 45.

[0059] The fixing between the rotating cylinder 5 and the fixed ring 32 can be achieved in the following way: a plurality of through holes 321 are arranged on the side wall of the fixed ring 32 in a circumferential direction, a plurality of clamping blocks 53 are arranged on the outer wall of the first end of the rotating cylinder 5 in a circumferential direction, the rotating cylinder 5 can be inserted into the fixed ring 32, and the clamping blocks 53 can be buckled in the corresponding through holes 321. Of course, other ways can also be used to fix the rotating cylinder 5 and the fixed ring 32, and the embodiment is only for illustration. A limiting step can also be arranged on the inner wall of the first convex ring 44, and after the first end of the rotating cylinder 5 is inserted into the fixed ring 32, the limiting step can abut against the end of the fixed ring 32.

[0060] In order to facilitate the automatic rotation of the spray arm 4, the direction of the nozzle 42 has certain requirements, specifically: at least one set of nozzle assemblies is arranged on the surface of the spray arm 4 facing the cover 14 (i.e. the second surface), each set of nozzle assemblies includes two nozzles 42, and the two nozzles 42 are centrally symmetric relative to the center point of the mounting hole 43; the axis of the nozzle 42 is arranged outwardly inclined from the mounting hole 43 to the corresponding end of the spray arm 4, and the axis of the nozzle 42 has an included angle with the plane passing through the center of the nozzle 42 and the center of the mounting hole 43 and perpendicular to the surface of the spray arm 4 (i.e. the second surface), so that the functional fluid medium sprayed out of the nozzle 42 has a tangential component in the circumferential direction, achieving the effect of automatic rotation of the spray arm 4.

[0061] For the above-mentioned cover 14, in order to facilitate its connection with the cover body 1, the cover 14 includes a baffle plate 141, a plurality of legs 142 are arranged on the plate surface of the baffle plate 141 facing the cover body 1 in a circumferential direction, one end of the leg 142 is fixedly connected with the baffle plate 141 by a fastener, the other end is fixedly connected with the cover body 1 by a fastener, the baffle plate 141 is arranged in a spaced manner with the back surface of the cover body 1 and encloses the above-mentioned cavity 15 with the cover body 1; a fixed shaft 1411 is fixedly arranged on the baffle plate 141. For the above-mentioned cover body 1, the cover body 1 generally has a cover edge 11 around the back surface of the cover body 1, the back surface of the cover body 1 is enclosed by the cover edge 11 and the baffle plate 141 to form the above-mentioned cavity 15, and the edge of the cover edge 11 and the baffle plate 141 form the above-mentioned annular opening; the second end of the fluid pipeline 3 can be inserted through the cover edge 11 of the rear end 102 of the cover body 1 to be connected with the functional fluid storage device; the inner side surface of the cover edge 11 and the surface of the baffle plate 141 and the leg 142 can also be subjected to corresponding functional actions during the operation of the functional component.

[0062] It can be understood that the outer peripheral surface of the cover 14 (specifically the outer peripheral surface of the baffle plate 141) can be matched with the shape of the inner peripheral surface of the seat ring 2, and the outer peripheral surface of the seat ring 2 is matched with the shape of the cover edge 11 of the cover body 1; after the seat ring 2 covers the cover body 1, the inner side of the seat ring 2 can be matched with the outer side of the cover 14, the outer side of the seat ring 2 is arranged in the inner side of the cover edge 11, and the seat ring 2 is hidden in the back surface of the cover body 1.

[0063] In one embodiment, there is no sealing ring structure on the cover 1 or the cover 14, and the seat ring 2 is covered on the cover 1, the inner ring of the seat ring 2 is attached to the outer ring of the cover 14, and the outer ring of the seat ring 2 is close to the inner side of the cover edge 11 of the cover 1. However, there is no sealing, the cover is not tight, and there is still a small gap between the seat ring 2 and the cover 14 and between the seat ring 2 and the cover edge 11 of the cover 1. When the functional fluid medium is injected into the cavity 15, the fluid will continuously overflow and discharge from these gaps while filling the cavity 15. Since the gap is small, the amount of overflow is also small and will not harm the human body.

[0064] In another preferred embodiment, in the state of covering the seat ring 2 and the cover 1, the seat ring 2 can block the annular opening and form a sealed cavity in the cavity 15, and the cover 1 is further provided with a discharge port communicating with the sealed cavity. The discharge port can be communicated with the sewer of the toilet or other containers, and the functional fluid medium can be continuously discharged from the discharge port during the functional operation, so as to avoid the pressure in the cavity 15. In this way, the leakage of steam or sterilizing agent can be completely avoided during steam sterilization or sterilization with sterilizing agent, and the sterilization is truly harmless, which is safer to use. Especially for sterilization with sterilizing agent, the sterilizing liquid can be discharged to the sewer of the toilet or other designated positions through the discharge port, so as to avoid liquid spilling.

[0065] Further, the movement of the cover plate and the seat ring 2 can be as follows:

[0066] The first way: using the conventional way

[0067] Referring to Figure 1 , Figure 2 , Figure 6 and Figure 7 , the rear end of the seat ring 2 is rotatably connected with a hinge seat 6, the rear end 102 of the cover 1 is rotatably connected with the rear end of the seat ring 2, and the hinge seat 6 is used to be detachably fixed on the toilet body 9.

[0068] Generally, two protrusions 21 are arranged at the rear end of the seat ring 2, and the hinge seat 6 is a rod-shaped seat body, and the two protrusions 21 of the seat ring 2 are rotatably connected with the two ends of the hinge seat 6. Two mounting seats 12 are arranged on both sides of the rear end 102 of the cover 1, and the plate body between the two mounting seats 12 constitutes part of the cover edge 11, and the part of the plate body forms an opening 13 in front of the two mounting seats 12. The hinge seat 6 and the two protrusions 21 are embedded in the opening 13 and rotatably connected with the two mounting seats 12. The bottom of the hinge seat 6 is provided with two mounting plates 61, and the mounting plates 61 can be fixed on the toilet body 9 by fasteners. The more specific structure of the rotatable connection is the existing structure, which will not be described here.

[0069] The second way: using the unconventional way

[0070] Referring to Figures 8 to 15 , the front surface of the cover body 1 can always face the user. In this way, when the functional operation is performed, the seat ring 2 is completely hidden on the back surface of the cover body 1, and the front surface of the cover body 1 always faces the user, which is more comfortable for the user's sense, and even if the seat ring 2 and the cover body 1 are closed and not completely sealed, the steam, ultraviolet rays, etc. will not float or irradiate the user under the shielding of the cover body 1, which can reduce or avoid the adverse effects on the user during the functional operation.

[0071] It should be noted that the front surface of the cover body 1 can always face the user means that when the cover body 1 is in the closed position, the front surface thereof faces away from the toilet bowl opening 92 of the toilet body 9, and during the movement of the cover body 1 from the closed position to the open position, the front surface thereof gradually moves from facing away from the toilet bowl opening 92 to facing the toilet bowl opening 92; so that in any state, the front surface of the cover body 1 always faces (or faces) the user (here, facing or facing does not require that the front surface of the cover body 1 is strictly parallel to the human body or directly opposite). The cover body 1 in the closed position means the position when the cover body 1 falls to the limit and covers the toilet body 9, and the cover body 1 in the open position means the position when the cover body 1 rises to the limit.

[0072] In the second mode, the connection between the cover body 1 and the seat ring 2 and the toilet body 9 can adopt the following mode:

[0073] The cover body 1 is hinged to the toilet body 9 through the first connecting assembly 7, and the seat ring 2 is hinged to the cover body 1 through the second connecting assembly 8.

[0074] More specifically, two groups of first connecting assemblies 7 are symmetrically arranged on the back surface of the cover body 1, each group of first connecting assemblies 7 includes two connecting arms 71, and the two connecting arms 71 are arranged at intervals along the length direction of the cover body 1; the first end of the connecting arm 71 is hinged to the cover body 1, the second end thereof is hinged to the toilet body 9, and the distance between the second ends of the two connecting arms 71 is greater than the distance between the first ends of the two connecting arms 71. Among them, a mounting groove 911 is formed on the toilet body 9 (specifically on the fixed cover plate 91 of the rear part 902 of the toilet body 9), and the second end of the connecting arm 71 is inserted into the mounting groove 911 and hinged to the toilet body 9. The two connecting arms 71 and the parts of the cover body 1 between the first ends of the two connecting arms 71 and the parts of the toilet body 9 between the second ends of the two connecting arms 71 constitute a four-bar linkage mechanism, and the four-bar linkage mechanism has a more stable form of structure and can keep the structure stable when the cover body 1 is in the open position.

[0075] The second connecting assembly 8 is symmetrically arranged on the back of the cover 1. Each second connecting assembly 8 includes a connecting seat 81, a first connecting rod 82, a second connecting rod 83, a third connecting rod 84, a fourth connecting rod 85 and a fifth connecting rod 86. The connecting seat 81 is fixedly arranged on the back of the cover 1. An arc-shaped sliding groove 8121 and a straight sliding groove 8122 are formed on the connecting seat 81. The first end of the first connecting rod 82 is hingedly connected to the connecting seat 81. The second end of the first connecting rod 82 is hingedly connected to the first end of the second connecting rod 83. The second end of the second connecting rod 83 is hingedly connected to the first end of the third connecting rod 84. The second end of the third connecting rod 84 is hingedly connected to the corresponding side surface of the seat ring 2. The first end of the fourth connecting rod 85 is hingedly connected to the first end of the first connecting rod 82 and is slidably inserted into the arc-shaped sliding groove 8121. The second end of the fourth connecting rod 85 is hingedly connected to the first end of the fifth connecting rod 86 and is slidably inserted into the straight sliding groove 8122. The fifth connecting rod 86 is arranged across the second connecting rod 83. The middle part of the fifth connecting rod 86 is hingedly connected to the middle part of the second connecting rod 83. The second end of the fifth connecting rod 86 is hingedly connected to the corresponding side surface of the seat ring 2.

[0076] The first connecting rod 82, the second connecting rod 83, the third connecting rod 84, the fourth connecting rod 85 and the fifth connecting rod 86 in each second connecting assembly 8 and the part of the seat ring 2 between the second end of the third connecting rod 84 and the second end of the fifth connecting rod 86 constitute a six-bar linkage mechanism. The first connecting assembly 7 is preferably arranged outside the adjacent second connecting assembly 8 to avoid interference between the first connecting assembly 7 and the second connecting assembly 8. Figure 9 and Figure 10As shown, the connecting seat 81 is located at the middle of the length direction of the cover body 1, which can be a long strip-shaped seat body composed of a first plate body 811 and a second plate body 812 connected perpendicularly to each other, the plate surface of the first plate body 811 is parallel to the back surface of the cover body 1 and is fixed to the cover body 1 by fasteners (such as screws), the plate surface of the second plate body 812 is perpendicular to the back surface of the cover body 1, and an arc-shaped sliding groove 8121 and a straight sliding groove 8122 are both arranged on the second plate body 812. The arc-shaped sliding groove 8121 is a C-shaped groove, and the C-shaped opening 13 thereof faces the back surface of the cover body 1; the hinge point position of the first connecting rod 82 and the connecting seat 81 can be located at the second plate body 812 surrounded by the C-shaped groove, and a first connecting shaft 851 is protruded at the first end of the fourth connecting rod 85, which can rotatably pass through the first connecting rod 82 to realize the hinge connection of the two, and after passing through the first connecting rod 82, the first connecting shaft 851 can be slidably inserted into the arc-shaped sliding groove 8121. The straight sliding groove 8122 is a straight sliding groove, and the length direction thereof is parallel to the length direction of the cover body 1; a second connecting shaft 852 is protruded at the second end of the fourth connecting rod 85, which can rotatably pass through the fifth connecting rod 86 to realize the hinge connection of the two, and after passing through the fifth connecting rod 86, the second connecting shaft 852 can be slidably inserted into the straight sliding groove 8122.

[0077] The arc-shaped sliding groove 8121 is arranged close to the rear end 102 of the cover body 1, the straight sliding groove 8122 is arranged close to the front end 101 of the cover body 1, the hinge point position of the second end of the third connecting rod 84 and the seat ring 2 is arranged close to the front end of the seat ring 2, and the hinge point position of the second end of the fifth connecting rod 86 and the seat ring 2 is arranged close to the rear end of the seat ring 2. In addition, the rod body of the second connecting rod 83 is located outside the rod body of the first connecting rod 82, and the rod body of the third connecting rod 84 is located outside the rod body of the second connecting rod 83; the rod body of the fourth connecting rod 85 is located outside the rod body of the first connecting rod 82 and the rod body of the fifth connecting rod 86, and the rod body of the second connecting rod 83 is located outside the rod body of the fifth connecting rod 86, so that the connecting rods do not interfere with each other when the seat ring 2 is entirely hidden on the back surface of the cover body 1, and the state of the connecting rods at this time is as shown in Figure 14 and Figure 15 At the same time, the second connecting rod 83 and the fifth connecting rod 86 are preferably bent rods, which can avoid the interference between the second connecting rod 83 and the fifth connecting rod 86 and other rod bodies (mainly the fourth connecting rod 85) when the seat ring 2 is entirely hidden on the back surface of the cover body 1. The bending part of the second connecting rod 83 and the fifth connecting rod 86 is located at the middle of the rod body, and the hinge point position of the two is also at the bending position.

[0078] When the cover 1 is in the open position, the seat 2 can be moved between the closed position and the open position by the action of the second connecting assembly 8, or the seat 2 can be entirely hidden at the back of the cover 1. After the seat 2 is entirely hidden at the back of the cover 1, the cover 1 and the seat 2 can be synchronously moved together by the action of the first connecting assembly 7. Moreover, when the cover 1 and the seat 2 are both in the open position, if the seat 2 needs to be used, the seat 2 can be directly extended from the back of the cover 1 without moving the cover 1, which is simple and convenient. When the seat 2 is entirely hidden at the back of the cover 1, i.e., the seat 2 is closed on the cover 1, the corresponding functional operation can be performed by using the functional components described above.

[0079] Meanwhile, the cover 1 and the seat 2 can be moved up and down in the width range of the toilet body 9. In the above two connection modes, when the cover 1 is moved between the closed position and the open position, the moving track of the cover 1 includes up and down movement, forward and backward movement, and up and down swinging movement. During the movement of the cover 1 from the closed position to the open position, the front end 101 of the cover 1 swings downward, the rear end 102 of the cover 1 swings upward, and the cover 1 moves backward and upward as a whole until it reaches the open position, at which time the rear end 102 of the cover 1 is above the front end 101 of the cover 1, and the front end 101 of the cover 1 is close to the rear part 902 of the toilet body 9. During the movement of the cover 1 from the open position to the closed position, the front end 101 of the cover 1 swings upward, the rear end 102 of the cover 1 swings downward, and the cover 1 moves forward and downward as a whole until it reaches the closed position, at which time the front end 101 of the cover 1 is close to the front part 901 of the toilet body 9, and the rear end 102 of the cover 1 is close to the rear part 902 of the toilet body 9. The movement of the seat 2 is similar to that of the cover 1, and thus is not described again.

[0080] In this connection mode, the movement of the cover 1 and the seat 2 is performed in the width range of the toilet body 9, and does not occupy the space on the left and right of the toilet, and occupies less space when moving, which is more suitable for small toilets. It can be understood that the front end 101 and the rear end 102 of the cover 1 are arranged opposite to each other along the length direction of the cover 1, and the front part 901 and the rear part 902 of the toilet body 9 are arranged opposite to each other along the length direction of the toilet body 9.

[0081] Of course, the connection between the cover 1, the seat 2 and the toilet body 9 is not limited to the above connection mode, and other connection modes can be used according to actual needs, as long as the front of the cover 1 can always face the user.

[0082] In addition, in an alternative embodiment, when the functional component employs an ultraviolet lamp, the ultraviolet lamp is directly fixed on the back of the cover 1, and the fluid conduit 3 described above can not be arranged on the cover 1. In this case, whether the seat ring 2 is covered on the cover 1 or not, the ultraviolet sterilization can be performed due to the shielding effect of the cover 14, and the adverse effect on the user during the ultraviolet sterilization can be reduced or avoided.

[0083] In another embodiment, when the fluid conduit 3 described above is arranged on the cover 1, the ultraviolet lamp can also be arranged on the back of the cover 1. After the seat ring 2 is covered on the cover 1, the functional fluid medium injected in the fluid conduit 3 can perform the corresponding functional operation while the ultraviolet lamp works simultaneously, and the effect of the ultraviolet sterilization is added on the basis of the effect of the functional fluid medium. Of course, in this embodiment, when the seat ring 2 is not covered on the cover 1, the ultraviolet lamp can also be used to perform the ultraviolet sterilization on the cover 1 due to the shielding effect of the cover 14, and the use is more flexible.

[0084] Further, the embodiment also provides a toilet, which comprises the toilet body 9 and the cover plate assembly described above. The whole toilet has the cover plate assembly described above, and thus has the same effect as the cover plate assembly described above, which will not be described here.

[0085] The above is only a specific embodiment of the present application, and is not used to limit the scope of the present application. Any equivalent changes and modifications made by those skilled in the art without departing from the concept and principles of the present application shall fall within the scope of protection of the present application.
