Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of toilet bowl cleaning, and in particular to a cover plate assembly and a toilet bowl. BACKGROUND

[0002] The seat of a toilet bowl is used frequently and is in direct contact with the user's skin during use. In order to improve the cleanliness of the seat of the toilet bowl, sterilization, cleaning, drying and other cleaning work need to be performed. The existing cleaning work of the toilet bowl is generally performed when the cover plate is closed, so as to avoid adverse effects (even harm) on the human body. However, this way limits the cleaning time of the toilet bowl and is inconvenient for the user to use the toilet bowl. For example, taking sterilization as an example, the common sterilization methods for toilet bowls at present include steam sterilization / ultraviolet sterilization, etc. These sterilization methods need to be performed when the cover plate is closed due to the harm to the human body, which results in that the user cannot use the toilet bowl when sterilization is performed. At the same time, the conventional sterilization methods need a certain period of time to achieve good sterilization effect, which requires the toilet bowl to be unable to be used for a relatively long period of time, which needs to be waited for or forcibly stopped for sterilization work in public places with high use frequency or in some emergency situations.

[0003] Therefore, the present application is proposed by the present inventor based on years of experience and practice in the relevant industry to overcome the defects of the prior art. SUMMARY

[0044] In order to have a clearer understanding of the technical features, objects and effects of the present application, the specific embodiments of the present application will be described with reference to the drawings.

[0045] As shown in Figures 1 to 14 , the present embodiment provides a cover plate assembly applied to a toilet, which comprises a cover body 1 and a seat ring 2. Both the cover body 1 and the seat ring 2 can be swinged in a pitching manner within the width range of the toilet body 7 from the closed position to the open position or from the open position to the closed position, and the front surface of the cover body 1 can always face the user.

[0046] In the installation, the cover plate assembly can be fixedly connected to the toilet body 7 to form an integral whole, which can be replaced as a whole later; or the cover plate assembly can also be a separate accessory and can be detachably installed on the toilet body 7, which can be adapted to various existing toilet bodies 7, and the cover plate assembly can be replaced separately without the need to replace the toilet body 7 as a whole. It should be noted that the closed position of the cover body 1 refers to the position when the cover body 1 falls to the limit and covers the toilet body 7, and the open position of the cover body 1 refers to the position when the cover body 1 rises to the limit. The closed position of the seat ring 2 refers to the position when the seat ring 2 falls to the limit and adheres to the upper surface of the toilet body 7, and the open position of the seat ring 2 refers to the position when the seat ring 2 rises to the limit. The cover body 1 and the seat ring 2 can be moved separately, or can be moved synchronously. The front of the cover body 1 can always face the user, which means that when the cover body 1 is in the closed position, the front of the cover body 1 faces away from the toilet opening 72 of the toilet body 7, and during the movement of the cover body 1 from the closed position to the open position, the front of the cover body 1 gradually moves from facing away from the toilet opening 72 to facing the toilet opening 72, so that the front of the cover body 1 always faces (or faces) the user in any state (here, facing or facing does not require the front of the cover body 1 to be strictly parallel to the human body or directly opposite).

[0047] Therefore, in the cover plate assembly of the present embodiment, the front of the cover body 1 always faces the user regardless of the position of the cover body 1, and the user's sensory comfort is improved. Moreover, the cover body 1 and the seat ring 2 can move simultaneously or separately, and the movement is performed within the width range of the toilet body 7, without occupying the space on the left and right of the toilet, and the space occupied is smaller, which is more suitable for small bathrooms.

[0048] In the specific implementation, in order to expand the timing of functional operation on the toilet while reducing or avoiding adverse effects on the human body, and to facilitate the user to use the toilet, a functional component is arranged on the back of the cover body 1 and / or the front of the seat ring 2, and the functional component is configured to perform a functional operation in a state where the seat ring 2 is at least partially hidden on the back of the cover body 1 or in a state where the seat ring 2 is in its open position and the cover body 1 is in its closed position.

[0049] The above-mentioned functional component includes but is not limited to a sterilization component, a cleaning component, and / or a drying component, etc., to perform corresponding sterilization (or disinfection), cleaning, and / or drying, etc. functional operations on the toilet; for example, when the functional component adopts a sterilization component such as ultraviolet sterilization, steam sterilization, sterilization agent sterilization, etc., the sterilization operation can be performed. The installation position of the functional component can be installed on the back of the cover body 1 and / or the seat ring 2 as needed, for example, the installation on the back of the cover body 1 is more preferred in the present embodiment.

[0050] The functional components can perform functional operations, especially ultraviolet sterilization, steam sterilization and other sterilization methods, which can cause certain harm to the human body. In this embodiment, in one case, the seat ring 2 can be at least partially hidden behind the cover body 1, and the functional operations can be performed at this time. At this time, because the front surface of the cover body 1 always faces the user, and the cover body 1 can at least partially shield the seat ring 2, the harm to the user during the functional operations such as sterilization can be effectively reduced or avoided. Therefore, even if the cover body 1 and the seat ring 2 are not both in the closed position, the functional components can still perform corresponding functional operations, and the timing of the functional operations on the toilet is more, and the timing of the functional operations does not require that the toilet must not be used before the functional operations are performed. For example, in a scenario where the toilet is used frequently, the functional components can perform sterilization and other functional operations during the movement of the cover body 1 or the seat ring 2 between the open position and the closed position, and the harm to the user can be reduced or avoided. In this way, the waiting time for the functional operations before use is reduced while the sterilization and other functional operations are performed as much as possible, thereby facilitating the use of the toilet by the user. For another example, when the cover body 1 and the seat ring 2 are both in the open position without the use of the seat ring 2, the user (usually a man) can use the toilet to urinate, and the functional components can simultaneously perform sterilization and other functional operations, thereby reducing the waiting time of the user and avoiding or reducing the harm to the user, and facilitating the use of the toilet by the user. In another case, the seat ring 2 can be in the open position and the cover body 1 can be in the closed position, and the functional operations can also be performed at this time. At this time, the cover body 1 covers the toilet body 7, and the functional components on the cover body 1 can perform sterilization and other functional operations on the toilet body 7, and the seat ring 2 can remain dry.

[0051] Therefore, the functional components are arranged on the bottom surface of the cover body 1 and / or the seat ring 2, the front surface of the cover body 1 can always face the user, and the functional operations can be performed as long as the seat ring 2 can be at least partially hidden behind the cover body 1, and the adverse effects on the user during the functional operations can be reduced or avoided, thereby expanding the timing of the functional operations on the toilet while reducing or avoiding the adverse effects on the user, and facilitating the use of the toilet by the user. In addition, because the cover body 1 can be closed alone, sterilization and other functional operations can be performed on the toilet body 7 (for example, the inner wall of the toilet body 7), and the seat ring 2 can be kept dry.

[0052] In practical applications, the cover body 1 and the seat ring 2 can be moved respectively to achieve that: when the seat ring 2 is in the open position and the closed position, the seat ring 2 is entirely hidden behind the cover body 1; and when the seat ring 2 is in a state of movement between the open position and the closed position, the seat ring 2 is partially hidden behind the cover body 1.

[0053] Alternatively, with the seat ring 2 completely hidden behind the cover 1, the cover 1 and the seat ring 2 can also move synchronously to achieve the following: the seat ring 2 is completely hidden behind the cover 1 whether it is in its open position, closed position, or moving between the open and closed positions.

[0054] In some embodiments, the seat ring 2 is at least partially hidden behind the cover 1, including the following states:

[0055] Both the cover 1 and the seat ring 2 are in the closed position;

[0056] Both the cover 1 and the seat ring 2 are in the open position;

[0057] The cover 1 is in the open position, and the seat ring 2 is moving between its open and closed positions;

[0058] In addition, the seat ring 2 is completely hidden behind the cover 1 and moves synchronously with the cover 1.

[0059] In other embodiments, the state in which the seat ring 2 is at least partially hidden on the back of the cover 1 also includes a state in which the seat ring 2 is in an open position and the cover 1 moves between its open and closed positions.

[0060] More specifically, taking the sterilization component as an example, the cover assembly in this embodiment can have the following seven working states during actual use, as detailed below:

[0061] First state: Both cover 1 and seat ring 2 are in the closed position.

[0062] like Figure 1 As shown, when both the lid 1 and the seat 2 are in the closed position, the sterilization component can perform sterilization (sterilizing the seat 2, lid 1, and toilet body 7 simultaneously). With both lid 1 and seat 2 in the closed position, germs and odors inside the toilet body 7 can be prevented from escaping, helping to maintain bathroom cleanliness. Therefore, this state can be considered the normal or initial state of the lid assembly. Before the user uses the toilet, the lid assembly can switch from the normal state to other states to meet the user's needs. After the user uses the toilet, the lid assembly can return to the normal state from other states.

[0063] Second state: Both cover 1 and seat ring 2 are in the open position.

[0064] like Figure 2As shown, when both the lid 1 and the seat ring 2 are in the open position, the sterilization component can perform sterilization (it can sterilize both the seat ring 2 and the lid 1 at the same time), and the user (usually a man) can use the toilet to urinate standing up; since the seat ring 2 is located under the back of the lid 1 in this state, the sterilization component will not harm the user when it sterilizes the lid 1 under the cover of the lid 1; thus, it satisfies the user's need to use the toilet while achieving sterilization without harm.

[0065] Third state: Cover 1 is in the open position, seat ring 2 is in the closed position.

[0066] like Figure 3 , Figure 4 and Figure 11 As shown, when the lid 1 is in the open position and the seat ring 2 is in the closed position, the user can use the toilet for urination or defecation. In this state, since the lid 1 cannot cover the seat ring 2, the seat ring 2 is completely exposed, and the sterilization component should avoid performing sterilization to prevent injury to the user.

[0067] Fourth state: Cover 1 is in the open position, and seat ring 2 moves between the closed and open positions.

[0068] like Figure 12 As shown, when the lid 1 is in the open position and the seat ring 2 moves between the closed and open positions, the user cannot use the toilet. However, in this state, since the seat ring 2 can be at least partially hidden behind the lid 1 during its movement, the sterilization component can reduce harm to the user (near a user waiting to use the toilet, or a user who has just used it and has not yet left) during the sterilization process, thereby improving the sterilization efficiency. The movement of the seat ring 2 between the closed and open positions can refer to the seat ring 2 moving from the closed position to the open position, or from the open position to the closed position. After the seat ring 2 completes its movement from the closed position to the open position, the lid assembly switches to the second state described above; after the seat ring 2 completes its movement from the open position to the closed position, the lid assembly switches to the third state described above.

[0069] Fifth state: Seat ring 2 is in the open position, cover 1 is in the closed position.

[0070] like Figure 13As shown, when the lid 1 is in the closed position and the seat 2 is in the open position, the user cannot use the toilet. This state generally occurs when the sterilization component is located on the lid 1; when the seat 2 is in the open position, the lid 1 is in the closed position, which is mainly for sterilizing the toilet body 7 (at this time, the sterilization component also incidentally sterilizes the back of the lid 1). Thus, since the lid 1 can be closed independently, the toilet body 7 (e.g., the inner wall of the toilet body 7) can be sterilized, and the seat 2 can be kept dry.

[0071] Sixth state: Seat ring 2 is in the open position, and cover 1 moves between the closed and open positions.

[0072] like Figure 14 As shown, when the seat ring 2 is in the open position and the lid 1 is moving between the closed and open positions, the user cannot use the toilet. However, in this state, since the lid 1 can at least partially cover the seat ring 2 during its movement, the sterilization component can reduce the harm to the user (near a user waiting to use the toilet, or a user who has just used the toilet and has not yet left) during the sterilization process, thereby improving the sterilization efficiency. The movement of the lid 1 between the closed and open positions can refer to the lid 1 moving from the closed position to the open position, or from the open position to the closed position. After the lid 1 completes its movement from the closed position to the open position, the lid assembly switches to the second state described above; after the lid 1 completes its movement from the open position to the closed position, the lid assembly switches to the fifth state described above.

[0073] Seventh state: The seat ring 2 and the cover 1 move synchronously between the closed position and the open position.

[0074] When switching between the first and second states described above is required, the seat ring 2 and the cover 1 can move synchronously between the closed and open positions during the switching process (of course, during the synchronous movement, the seat ring 2 remains completely hidden behind the cover 1). For example, when the cover assembly is in the first state, and a man wishes to urinate on the toilet, the seat ring 2 and the cover 1 can move synchronously from the closed position to the open position until entering the second state, making it convenient for the man to urinate. Similarly, when the cover assembly is in the second state, after the man finishes urinating, the seat ring 2 and the cover 1 can move synchronously from the open position to the closed position until entering the first state, restoring the cover assembly to its initial state.

[0075] It should be noted that in the above various working states, the target object of sterilization is mainly the seat ring 2, that is, the cleaning work such as sterilization (or disinfection) is mainly performed on the seat ring 2; of course, the cleaning work such as sterilization (or disinfection) can also be performed on the toilet body 7, the cover body 1, etc. in an incidental manner.

[0076] Further, the connection between the cover body 1 and the seat ring 2 and the toilet body 7 can adopt the following two connection modes, so that the cover body 1 and the seat ring 2 can move relative to the toilet body 7 between the open position and the closed position, which can not only include the cover body 1 and the seat ring 2 moving relative to the toilet body 7 between the open position and the closed position respectively, but also include the cover body 1 and the seat ring 2 moving relative to the toilet body 7 between the open position and the closed position synchronously, so as to realize at least part of the above working states of the cover plate assembly. Specifically as follows:

[0077] The first connection mode: as shown in Figures 2 to 10 , the cover body 1 is hinged to the toilet body 7 through the first connection assembly 3, and the seat ring 2 is hinged to the cover body 1 through the second connection assembly 4.

[0078] Among them, the second connection assembly 4 can be a multi-link mechanism.

[0079] More specifically, two groups of first connection assemblies 3 are symmetrically arranged on the back of the cover body 1, each group of first connection assemblies 3 includes two connecting arms 31, and the two connecting arms 31 are arranged in a length direction of the cover body 1. The first end of the connecting arm 31 is hinged to the cover body 1, the second end of the connecting arm 31 is hinged to the toilet body 7, and the distance between the second ends of the two connecting arms 31 is greater than the distance between the first ends of the two connecting arms 31. Among them, a mounting groove 711 is formed on the toilet body 7 (specifically on the fixed cover plate 71 of the rear part 702 of the toilet body 7), and the second end of the connecting arm 31 is inserted into the mounting groove 711 and hinged to the toilet body 7. The parts of the cover body 1 between the two connecting arms 31 and the first ends of the two connecting arms 31 and the parts of the toilet body 7 between the second ends of the two connecting arms 31 constitute a four-link mechanism, and the four-link mechanism has a more stable structure and can maintain structural stability when the cover body 1 is in the open position.

[0080] The second connecting assembly 4 is symmetrically arranged on the back of the cover 1. Each second connecting assembly 4 includes a connecting seat 41, a first connecting rod 42, a second connecting rod 43, a third connecting rod 44, a fourth connecting rod 45 and a fifth connecting rod 46. The connecting seat 41 is fixedly arranged on the back of the cover 1. An arc-shaped sliding groove 4121 and a straight sliding groove 4122 are formed on the connecting seat 41. The first end of the first connecting rod 42 is hingedly connected to the connecting seat 41. The second end of the first connecting rod 42 is hingedly connected to the first end of the second connecting rod 43. The second end of the second connecting rod 43 is hingedly connected to the first end of the third connecting rod 44. The second end of the third connecting rod 44 is hingedly connected to the corresponding side surface of the seat ring 2. The first end of the fourth connecting rod 45 is hingedly connected to the first end of the first connecting rod 42 and is slidably inserted into the arc-shaped sliding groove 4121. The second end of the fourth connecting rod 45 is hingedly connected to the first end of the fifth connecting rod 46 and is slidably inserted into the straight sliding groove 4122. The fifth connecting rod 46 is arranged in cross with the second connecting rod 43. The middle part of the fifth connecting rod 46 is hingedly connected to the middle part of the second connecting rod 43. The second end of the fifth connecting rod 46 is hingedly connected to the corresponding side surface of the seat ring 2.

[0081] The first connecting rod 42, the second connecting rod 43, the third connecting rod 44, the fourth connecting rod 45 and the fifth connecting rod 46 in each second connecting assembly 4 and the part of the seat ring 2 between the second end of the third connecting rod 44 and the second end of the fifth connecting rod 46 constitute a six-bar linkage mechanism. The position of each first connecting assembly 3 is preferably located outside the adjacent second connecting assembly 4 to avoid interference between the first connecting assembly 3 and the second connecting assembly 4. Figure 4 and Figure 5As shown, the connecting seat 41 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 411 and a second plate body 412 connected perpendicularly to each other, the plate surface of the first plate body 411 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 412 is perpendicular to the back surface of the cover body 1, and the arc-shaped sliding groove 4121 and the straight sliding groove 4122 are both provided on the second plate body 412. The arc-shaped sliding groove 4121 is a C-shaped groove, and the C-shaped opening thereof faces the back surface of the cover body 1; the hinge point position of the first connecting rod 42 and the connecting seat 41 can be located at the second plate body 412 surrounded by the C-shaped groove, and a first connecting shaft 451 is protruded at the first end of the fourth connecting rod 45, which can rotatably pass through the first connecting rod 42 to realize the hinge connection of the two, and after passing through the first connecting rod 42, the first connecting shaft 451 can be slidably inserted into the arc-shaped sliding groove 4121. The straight sliding groove 4122 is a straight linear sliding groove, and the length direction thereof is parallel to the length direction of the cover body 1; a second connecting shaft 452 is protruded at the second end of the fourth connecting rod 45, which can rotatably pass through the fifth connecting rod 46 to realize the hinge connection of the two, and after passing through the fifth connecting rod 46, the second connecting shaft 452 can be slidably inserted into the straight sliding groove 4122.

[0082] The arc-shaped sliding groove 4121 is arranged close to the rear end 102 of the cover body 1, the straight sliding groove 4122 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 44 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 46 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 43 is located outside the rod body of the first connecting rod 42, and the rod body of the third connecting rod 44 is located outside the rod body of the second connecting rod 43; the rod body of the fourth connecting rod 45 is located outside the rod bodies of the first connecting rod 42 and the fifth connecting rod 46, and the rod body of the second connecting rod 43 is located outside the rod body of the fifth connecting rod 46, 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 9 and Figure 10 At the same time, the second connecting rod 43 and the fifth connecting rod 46 are preferably bent rods, which can avoid the interference between the second connecting rod 43 and the fifth connecting rod 46 and other rod bodies (mainly the fourth connecting rod 45) 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 43 and the fifth connecting rod 46 is located at the middle of the rod body, and the hinge point position of the two is also at the bending position.

[0083] 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 4, 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 3. Through the arrangement of the first connecting assembly 3 and the second connecting assembly 4, the cover assembly can realize the five working states as described above, and the operation is flexible. Moreover, when the cover 1 and the seat 2 are both in the open position (i.e., the second state as described above), if the seat 2 needs to be used, the cover 1 can be kept stationary, and the seat 2 can be directly extended from the back of the cover 1, so that the cover assembly does not need to be closed first and then the cover is opened for use, which is simple and convenient.

[0084] The second connecting mode is shown in FIG. 2. The cover 1 is hinged to the toilet body 7 through the first mechanical assembly 5, and the seat 2 is hinged to the toilet body 7 through the second mechanical assembly 6. Figures 11 to 14

[0085] More specifically, two groups of the first mechanical assembly 5 are symmetrically arranged at the back of the cover 1, each group of the first mechanical assembly 5 including two first mechanical arms 51, which are arranged at intervals along the length direction of the cover 1. The first end of the first mechanical arm 51 is hinged to the cover 1, and the second end thereof is hinged to the toilet body 7, and the distance between the second ends of the two first mechanical arms 51 is greater than the distance between the first ends of the two first mechanical arms 51. Two groups of the second mechanical assembly 6 are symmetrically arranged at the back of the seat 2, each group of the second mechanical assembly 6 including one or two second mechanical arms 61. Each first mechanical arm 51 in each group of the first mechanical assembly 5 and / or each second mechanical arm 61 in each group of the second mechanical assembly 6 is an electric telescopic arm.

[0086] When each group of the second mechanical assembly 6 includes two second mechanical arms 61, the two second mechanical arms 61 are arranged at intervals along the length direction of the seat 2. The first end of the second mechanical arm 61 is hinged to the seat 2, and the second end thereof is hinged to the toilet body 7, and the distance between the second ends of the two second mechanical arms 61 is greater than the distance between the first ends of the two second mechanical arms 61. Figures 11 to 14

[0087] ​​The installation groove 711 is formed on the toilet body 7, in particular, on the fixed cover plate 71 of the rear portion 702 of the toilet body 7, and the second end of the first mechanical arm 51 and the second end of the second mechanical arm 61 are inserted into the installation groove 711 and are hinged to the toilet body 7. The position of each set of first mechanical assemblies 5 is preferably located outside the adjacent set of second mechanical assemblies 6 to avoid interference between the first mechanical assemblies 5 and the second mechanical assemblies 6. Meanwhile, each first mechanical arm 51 in each set of first mechanical assemblies 5 and / or each second mechanical arm 61 in each set of second mechanical assemblies 6 is an electric telescopic arm, and a corresponding driving structure (such as a motor) is provided to drive the electric telescopic arm to extend and retract. In this way, when the cover body 1 and / or the seat ring 2 move, the telescopic function of the corresponding electric telescopic arm can be used to avoid interference between the cover body 1 and the seat ring 2, ensuring smooth movement of both.

[0088] For the cover body 1, the part of the cover body 1 between the two first mechanical arms 51 and the first ends of the two first mechanical arms 51 and the part of the toilet body 7 between the second ends of the two first mechanical arms 51 form a four-bar linkage mechanism, which is more stable in structure and can maintain stability when the cover body 1 is in the open position. For the seat ring, when each set of second mechanical assemblies 6 includes two second mechanical arms 61, the part of the seat ring 2 between the two second mechanical arms 61 and the first ends of the two second mechanical arms 61 and the part of the toilet body 7 between the second ends of the two second mechanical arms 61 also form a four-bar linkage mechanism, which can maintain stability when the seat ring 2 is in the open position alone. When each set of second mechanical assemblies 6 includes one second mechanical arm 61, the seat ring 2 may

[0089] In the above two connection modes, the cover 1 has a moving track including lifting movement, forward and backward movement and pitching swing movement when it moves between the closed position and the open position. 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 the limit 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 portion 702 of the toilet body 7. 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 by being closed on the toilet body 7, at which time the front end 101 of the cover 1 is close to the front portion 701 of the toilet body 7, and the rear end 102 of the cover 1 is close to the rear portion 702 of the toilet body 7. The movement of the seat 2 is similar to that of the cover 1, and thus is not described again. The movement of the cover 1 and the seat 2 is all within the width range of the toilet body 7, and does not occupy the space on the left and right of the toilet. It can be understood that the front end 101 and the rear end 102 of the cover 1 are oppositely arranged along the length direction of the cover 1, and the front portion 701 and the rear portion 702 of the toilet body 7 are oppositely arranged along the length direction of the toilet body 7.

[0090] Of course, the connection between the cover 1 and the seat 2 and the toilet body 7 is not limited to the above two connection modes, and other connection modes can also be used according to actual needs, as long as at least part of the aforementioned working states can be conveniently realized.

[0091] In a preferred embodiment, the functional component performs functional operation only when the seat 2 is entirely hidden on the back of the cover 1. In this way, the seat 2 is entirely covered by the cover 1, and especially when ultraviolet sterilization or steam sterilization is performed, ultraviolet irradiation to the user or steam leakage to hurt the user can be more effectively avoided, and basic harmless sterilization is realized.

[0092] In a more preferred embodiment, the functional component performs functional operation only when the seat 2 is entirely hidden on the back of the cover 1 and forms a sealed cavity with the cover 1. That is, when the seat 2 is closed with the cover 1, a sealed cavity can be formed therebetween, and at this time, functional operation such as sterilization is performed. In this way, especially when steam sterilization or sterilization agent sterilization is performed, leakage of steam or sterilization agent can be completely avoided, and truly harmless sterilization is realized, and the use is safer. It can be understood that in this embodiment, a corresponding channel is also provided to communicate with the sealed cavity, so that steam, sterilization agent or other gas or liquid is discharged.

[0093] Of course, the timing of the functional operation of the toilet can be determined according to the type of functional component and the customer's use requirements in actual use, and the present embodiment is only an example.

[0094] Further, the present embodiment also provides a toilet, which comprises a toilet body 7 and the cover plate assembly described above. The whole toilet has the cover plate assembly described above, and thus has the same effects as the cover plate assembly described above, which will not be described here again.

[0095] In summary, the cover plate assembly and the toilet in the present embodiment, the cover 1 and the seat 2 can move simultaneously or separately, and will not occupy the space on the left and right of the toilet during the movement, and the space occupied during the movement is small. At the same time, in addition to the functional component cannot perform functional operation when the cover 1 is in the open position and the seat 2 is in the closed position (i.e. the third state described above), at any other time, whether the cover 1 and / or the seat 2 are in the open or closed static state or in the process of moving between the open position and the closed position, the functional component can perform functional operation such as sterilization, and the timing of the functional operation of the toilet is more; and when the functional component works, the seat 2 can be located at the back of the cover 1 and be at least partially shielded by the cover 1, and the front of the cover 1 will always face the user, not only the user's sense is more comfortable, but also when the seat 2 is sterilized by ultraviolet light, under the shielding effect of the cover 1, there is no ultraviolet light irradiating to the user, which can reduce or avoid the adverse effects on the user during the functional operation. In addition, the cover 1 can also be closed alone and perform functional operation such as sterilization on the toilet body 7, and avoid wetting the seat 2.

[0096] 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.
