Description

Technical Field

[0001] This utility model relates to the field of bathroom facilities technology, and in particular to a linkage system, a toilet seat assembly, and a toilet. Background Technology

[0002] In some devices, a baffle is typically used to open and close the outlet, allowing it to be opened or closed at appropriate times. For example, in smart toilets with atomizing sterilization functions, the mist outlet is usually located between the seat and lid to ensure the atomization range covers the seat and the inner wall of the toilet. The sterilizing mist generated by the atomizing device is sprayed out through the outlet, with some landing on the inner wall of the toilet and some on the seat, simultaneously sterilizing both. However, this top-mounted outlet is prone to water, dust, and dirt entering, affecting the normal operation and hygiene performance of the device. To solve this problem, an outlet baffle is installed at the outlet. The baffle opens during operation to allow the atomized gas to escape, and closes when not in operation to prevent foreign objects from entering.

[0003] To maintain high atomization efficiency, toilet atomizing devices typically use relatively weak fans. In related technologies, if an atomizing fan is used, the airflow is insufficient to directly lift the outlet baffle, making it difficult to achieve automatic opening and closing of the outlet baffle during the sterilization process. Using an additional motor to control the baffle's opening and closing not only increases manufacturing costs and requires extra installation space for the motor, but also complicates the control logic and increases the toilet's failure rate.

[0004] Therefore, there is an urgent need for a linkage system, a toilet seat assembly, and a toilet to solve the aforementioned problems in the existing technology. Utility Model Content

[0005] The purpose of this utility model is to provide a linkage system, a toilet seat assembly, and a toilet, which can realize the automatic opening and closing of the baffle, reduce costs, save installation space, simplify control logic, and reduce the probability of failure.

[0030] When the moving mechanism moves from the retracted state to the extended state, it drives the outlet baffle from the closed state to the open state through the linkage mechanism.

[0034] This utility model provides a linkage system, a toilet seat assembly, and a toilet using the same assembly. When the motion mechanism moves, it drives the outlet baffle to move between a closed and open state via a linkage mechanism. By setting a linkage mechanism connecting the motion mechanism and the outlet baffle, the kinetic energy of the motion mechanism's extension and retraction can be used as a direct power source to drive the opening and closing of the outlet baffle.

When the linkage system is applied to the toilet seat assembly, and the outlet component is used to discharge functional substances (such as bactericidal substances, deodorizing substances, or other substances), the motion mechanism can drive the outlet baffle to automatically open and close, realizing the corresponding function.

[0068] The present invention will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the present invention and not intended to limit it. Furthermore, it should be noted that, for ease of description, the accompanying drawings show only the parts relevant to the present invention, not the entire structure.

[0069] In the description of this utility model, unless otherwise explicitly specified and limited, the terms "connected," "linked," and "fixed" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0070] In this invention, unless otherwise explicitly specified and limited, "above" or "below" the second feature can include direct contact between the first and second features, or contact between the first and second features through another feature between them. Furthermore, "above," "over," and "on top" of the second feature includes the first feature directly above or diagonally above the second feature, or simply indicates that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature includes the first feature directly below or diagonally below the second feature, or simply indicates that the first feature is at a lower horizontal level than the second feature.

[0071] In the description of this embodiment, the terms "upper," "lower," "left," and "right," etc., refer to the orientation or positional relationship shown in the accompanying drawings. They are used only for ease of description and simplification of operation, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. In addition, the terms "first" and "second" are only used for distinction in description and have no special meaning.

[0072] In this embodiment, the term "and / or" is merely a description of the relationship between associated objects, indicating that three relationships can exist. For example, A and / or B can represent: A existing alone, A and B existing simultaneously, or B existing alone. Additionally, in this invention, the character " / " generally indicates that the preceding and following associated objects have an "or" relationship.

[0073] In the embodiments of this utility model, the same reference numerals denote the same parts, and for the sake of brevity, detailed descriptions of the same parts are omitted in different embodiments.

[0074] like Figure 1As shown, this embodiment provides a toilet, including a toilet body 200, a functional device 300, and a toilet seat assembly 100. Both the seat assembly 100 and the functional device 300 are located on the toilet body 200. The seat assembly 100 provided in this embodiment is installed above the toilet body 200, enabling automatic opening and closing of the outlet baffle 5 at the toilet outlet 20 without the use of a motor or other driving components. This reduces costs, saves installation space, simplifies control logic, and lowers the probability of toilet malfunctions.

[0075] The toilet seat assembly 100 provided in this embodiment includes a linkage system, which includes an output component 2, a motion mechanism 3, and a linkage mechanism 4. The output component 2 is provided with an output port 20, and an openable and closable outlet baffle 5 is provided at the output port 20. The motion mechanism 3 is connected to the outlet baffle 5 via the linkage mechanism 4. When the motion mechanism 3 moves, it drives the outlet baffle 5 to move between a closed state and an open state via the linkage mechanism 4.

[0076] In the linkage system provided in this embodiment, when the motion mechanism 3 moves, it drives the outlet baffle 5 to move between a closed state and an open state via the linkage mechanism 4. By setting the linkage mechanism 4 connecting the motion mechanism 3 and the outlet baffle 5, the kinetic energy of the motion mechanism 3 extending and retracting itself can be used as a direct power source to drive the opening and closing of the outlet baffle 5. The movement of the motion mechanism 3 can drive the outlet baffle to open and close, thereby exposing or covering the output port 20, allowing the corresponding substance to be output smoothly from the output port 20, or sealing and protecting the output port 20, realizing the automatic opening and closing of the outlet baffle 5, reducing costs and saving space. When the linkage system is applied to the toilet seat assembly 100, and the output component 2 is used to output functional substances (such as bactericidal substances, deodorizing substances, or other substances), the motion mechanism 3 can drive the outlet baffle to open and close automatically, realizing the opening and closing of the corresponding function.

[0077] Specifically, in this embodiment, the cover assembly 100 further includes a mounting assembly 1. The mounting assembly 1 defines a mounting chamber 10. An output component 2 is disposed on the mounting assembly 1 and is connected to a functional device 300. The functional device 300 is used to introduce a functional substance, such as a bactericidal substance, a deodorizing substance, or other substances, into the output component 2. This embodiment does not limit the specific substance to this. A motion mechanism 3 is movably connected to the mounting assembly 1 and has a retracted state (containing the mounting chamber 10) and an extended state (extending out of the mounting chamber 10). A linkage mechanism 4 is connected between the motion mechanism 3 and the outlet baffle 5. When the motion mechanism 3 moves from the retracted state to the extended state, it drives the outlet baffle 5 from the closed state to the open state via the linkage mechanism 4.

[0078] It should be noted that the output port 20 can output air, sterilization mist, plasma, etc., and this embodiment does not impose strict limitations on it.

[0079] For example, the aforementioned functional device 300 is a toilet sterilization device, which can output sterilizing substances so that the sterilizing substances are output through the output port of the output component, such as in the form of a spray. Of course, the aforementioned functional device 300 can also be a deodorizing device or other devices, etc. This embodiment is only used as an example of a sterilization device for illustration and does not limit the functional device 300. The aforementioned motion mechanism 3 includes the toilet spray gun.

[0080] In this embodiment, the cover assembly 100, when the moving mechanism 3 moves from the retracted state to the extended state, drives the outlet baffle 5 from the closed state to the open state via the linkage mechanism 4, thereby exposing the outlet 20. The sterilizing airflow generated by the functional device 300 can be output through the outlet 20. The sterilizing airflow can disperse and adhere to the inner wall of the toilet and the moving mechanism 3 in the extended state, thereby achieving disinfection of the inner wall of the toilet and the moving mechanism 3. When the moving mechanism 3 moves from the extended state back to the retracted state, the outlet baffle 5 can be moved back to the closed state via the linkage mechanism 4, thereby covering the outlet 20 and preventing water, dust, and foreign objects from entering the output component 2 from the outlet 20 and causing contamination. The linkage mechanism 4 provides sufficient power to open the outlet baffle 5 smoothly, thereby achieving the sterilization and disinfection function. Compared with the related technologies that use additional motors or electronic control components to open the outlet baffle 5, the linkage mechanism 4 is a purely mechanical automatic control structure. This not only simplifies the control logic of the smart toilet, reduces the failure rate and production cost, but also saves space for arranging motors and other components, making the internal space utilization of the cover assembly 100 more efficient. This facilitates the miniaturization and thinning of the product and provides greater flexibility for the layout of other functional modules.

[0081] That is, when the user needs to activate the sterilization function, by driving the motion mechanism 3 to extend out of the installation chamber 10, the outlet baffle 5 can be opened simultaneously through the linkage mechanism 4. The functional device 300 can then start working, outputting sterilizing airflow through the output port 20 for sterilization, achieving simultaneous sterilization of the toilet inner wall and the extended part of the motion mechanism 3, avoiding the problem of contamination caused by the motion mechanism 3 not being sterilized for a long time. When sterilization is finished, the motion mechanism 3 is controlled to retract into the installation chamber 10, switching to the storage state. During this process, the outlet baffle 5 is automatically closed by the linkage mechanism 4, which can effectively prevent foreign objects from entering during non-working periods. Furthermore, the linkage mechanism 4 can also restrict the outlet baffle 5 in the closed state, preventing the outlet baffle 5 from opening accidentally, and ensuring that the outlet baffle 5 maintains a good sealing protection for the output port 20.

[0082] like Figure 4 and Figure 5As shown, the mounting assembly 1 is also provided with an openable and closable motion mechanism baffle 14 on the front side of the motion mechanism 3. When the motion mechanism 3 extends out of the mounting chamber 10, it can push open the motion mechanism baffle 14. When the motion mechanism 3 retracts into the mounting chamber 10, the motion mechanism baffle 14 automatically closes under the action of gravity.

[0083] like Figure 4 and Figure 5 The diagram shows the motion mechanism 3 in its retracted state, at which time the outlet baffle 5 is in a closed state, covering the output port 20. Figure 7 and Figure 8 As shown, the motion mechanism 3 is in the extended state, extending a certain distance from the mounting chamber 10. During this process, the linkage mechanism 4 drives the outlet baffle 5 to open, revealing the output port 20. Figure 9 and Figure 10 As shown, the motion mechanism 3 continues to extend, and during this process, the outlet baffle 5 remains in the open state, and the movement of the motion mechanism 3 no longer affects the outlet baffle 5.

[0084] like Figure 3 , Figure 4 as well as Figure 5 The linkage mechanism 4 includes a transmission rod 41, which slides in conjunction with the output component 2. Figure 6 and Figure 12 The outlet baffle 5 includes a baffle body 51 and a crank arm 52. The first end of the baffle body 51 is rotatably engaged with the output component 2 via a rotating shaft 54, and the crank arm 52 is connected to the second end of the baffle body 51. The first end of the transmission rod 41 is movably engaged with the motion mechanism 3, and the second end of the transmission rod 41 slidably abuts against the crank arm 52. The transmission rod 41 is used to reciprocate between a first position and a second position under the drive of the motion mechanism 3.

[0085] When the transmission rod 41 moves from the first position to the second position under the drive of the motion mechanism 3, it drives the baffle body 51 to rotate to the open state through the push arm 52. When the transmission rod 41 moves back to the first position from the second position, the baffle body 51 automatically rotates to the closed state under its own gravity to seal the output port 20. By driving the linear motion of the transmission rod 41 and the contact between the end of the transmission rod 41 and the push arm 52, the power is effectively transmitted and converted into the rotational motion of the baffle body 51, ensuring that the baffle body 51 can be reliably pushed open. Furthermore, the automatic reset is achieved by utilizing the gravity of the baffle body 51 itself, without the need for any other reset components, which simplifies the structure, reduces the number of parts, and further reduces manufacturing costs and assembly complexity.

[0086] Specifically, the sliding direction of the transmission rod 41 is vertical, and the baffle body 51 rotates around the horizontal axis to open and close the output port 20. The second end of the transmission rod 41 is located above the crank arm 52, and the first position of the transmission rod 41 is higher than the second position. When the transmission rod 41 slides from the first position to the second position, its second end presses down against the crank arm 52, thereby causing the crank arm 52 to drive the baffle body 51 to flip open, allowing the sterilizing airflow to pass smoothly through the output port 20. When the transmission rod 41 rises from the second position back to the first position, its second end moves away from the crank arm 52 and no longer presses against the crank arm 52. At this time, the baffle body 51 automatically flips to the closed output port 20 state under its own gravity. The sliding contact between the transmission rod 41 and the crank arm 52 ensures that the baffle body 51 can be driven to flip open while adapting to changes in their positions, avoiding jamming during movement.

[0087] like Figure 3 , Figure 5 as well as Figure 6 As shown, the linkage mechanism 4 also includes a transmission push block 42. The transmission push block 42 is connected to the motion mechanism 3 and moves synchronously with the motion mechanism 3. The transmission push block 42 is movably engaged with the first end of the transmission rod 41, which can drive the transmission rod 41 to reciprocate between the first position and the second position.

[0088] Specifically, the transmission push block 42 includes a mounting part 421 and a guide part 422. The mounting part 421 is connected to the motion mechanism 3, and the guide part 422 protrudes from the side of the mounting part 421 facing away from the motion mechanism 3. The guide part 422 includes a first guide structure 4221 and a second guide structure 4222 protruding from the mounting part 421 and connected to each other. When the transmission push block 42 moves under the drive of the motion mechanism 3, the first end of the transmission rod 41 can slidably abut against the first guide structure 4221 and the second guide structure 4222. When the transmission rod 41 abuts against the first guide structure 4221, it is in the first position, at which time the outlet baffle 5 is in the closed state. The transmission rod 41 can slide along the second guide structure 4222 to the second position, so that the outlet baffle 5 switches to the open state.

[0089] By using the protruding first guide structure 4221 and second guide structure 4222, the movement path of the transmission rod 41 can be limited, and the movement of the motion mechanism 3 between the retracted state and the extended state can be converted into the vertical sliding of the transmission rod 41. This ensures that the transmission rod 41 can move accurately from the first position to the second position and return along the same path, avoiding jamming, deviation or uncertainty in the movement process, and greatly improving the control accuracy of the entire linkage process.

[0090] Further, see Figure 6The first guide structure 4221 is provided with a first guide surface 4221a, and the second guide structure 4222 is provided with a second guide surface 4222a. The height of the first guide surface 4221a relative to the mounting part 421 is greater than the height of the second guide surface 4222a relative to the mounting part 421, and the second guide surface 4222a gradually approaches the mounting part 421 in a direction away from the first guide surface 4221a. When the transmission push block 42 moves under the drive of the motion mechanism 3, it slides with the first end of the transmission rod 41 through the first guide surface 4221a and the second guide surface 4222a. The transmission push block 42 is located below the transmission rod 41, and the height of the first guide surface 4221a relative to the mounting part 421 is higher. Therefore, under the pushing action of the first guide surface 4221a, the transmission rod 41 can be moved to the first position. The second guide surface 4222a gradually approaches the mounting part 421 in a direction away from the first guide surface 4221a. Therefore, when the transmission rod 41 slides with the second guide surface 4222a, it can gradually descend to the second position, thereby pressing down on the crank arm 52 to flip and open the outlet baffle 5.

[0091] The arrangement of the first guide surface 4221a and the second guide surface 4222a can improve the stability when sliding with the transmission rod 41, and can accurately guide the transmission rod 41 to move between the first position and the second position.

[0092] For example, the second guide surface 4222a is a guide arc surface or a guide slope surface, both of which can provide a stable guiding and pushing effect on the transmission rod 41.

[0093] like Figure 3 and Figure 6 As shown, the linkage mechanism 4 also includes an elastic element 43, which is connected between the output element 2 and the transmission rod 41. The transmission rod 41 can move from the first position to the second position under the elastic force of the elastic element 43 and elastically abut against the transmission push block 42 to realize the automatic opening of the outlet baffle 5.

[0094] Specifically, see Figure 5 and Figure 6 At this time, the motion mechanism 3 is in the retracted state, the outlet baffle 5 is in the closed state, and the transmission rod 41 is in the first position, abutting against the first guide surface 4221a under the elastic force of the elastic element 43. When the motion mechanism 3 extends out of the mounting chamber 10, the transmission push block 42 moves, and the transmission rod 41 abuts against and slides against the second guide surface 4222a under the elastic force of the elastic element 43. As the second guide surface 4222a gradually lowers, the transmission rod 41 descends from the first position to the second position under the elastic force of the elastic element 43, until it slides to... Figure 7 and Figure 8 The state shown.

[0095] like Figure 8As shown, at this time, the transmission rod 41 is in the second position, abutting against the end of the second guide surface 4222a away from the first guide surface 4221a, and the outlet baffle 5 is in a fully open state. When the motion mechanism 3 is... Figure 8 The state shown gradually becomes active until Figure 9 and Figure 10 In the state shown, the transmission push block 42 is separated from the transmission rod 41. At this time, the extension movement of the motion mechanism 3 no longer affects the transmission rod 41 and the outlet baffle 5. The transmission rod 41 is held in the second position under the elastic force of the elastic member 43, thereby maintaining the open state of the outlet baffle 5, so that the sterilization airflow can be continuously output.

[0096] like Figure 6 As shown, the output component 2 is provided with a guide hole 22, and the inner wall of the guide hole 22 is provided with a mounting groove 23; the transmission rod 41 slidably passes through the guide hole 22. Combined with... Figure 11 The transmission rod 41 has a first groove 4111 on its upper ring, and a stop 44 is engaged in the first groove 4111. The elastic member 43 is telescopically sleeved on the transmission rod 41 and abuts against the bottom wall of the mounting groove 23 and the stop 44. Specifically, the elastic member 43 is in a compressed state between the bottom wall of the mounting groove 23 and the stop 44, and can always provide elastic force to elastically abut against the first guide surface 4221a and the second guide surface 4222a. The mounting groove 23 and the stop 44 can improve the installation stability of the elastic member 43 and guide the extension and retraction of the elastic member 43, reducing the nonlinear deformation of the elastic member 43.

[0097] For example, the elastic element 43 is a spring, which is readily available and can provide sufficient elastic force. The stop element 44 can be a ring snap ring with an opening, which is inserted into the first snap ring 4111 through the opening for a secure and reliable installation.

[0098] like Figure 11 As shown, the transmission rod 41 includes a guide rod section 411 and a push rod section 412 arranged at an angle. The guide rod section 411 is slidably engaged with the guide hole 22 of the output component 2. The push rod section 412 has a push surface 4121 on one side along the sliding direction of the guide rod section 411, which is used to abut against the crank arm 52. The guide rod section 411 guides the transmission rod 41 to slide vertically along the guide hole 22. The push rod section 412 is located outside the guide hole 22 and is used to press down the crank arm 52 through the push surface 4121 under the drive of the guide rod section 411, thereby causing the baffle body 51 to flip open through the crank arm 52. Furthermore, when the push surface 4121 is pressed down or moves away from the crank arm 52, the push surface 4121 and the crank arm 52 are in a sliding abutment engagement.

[0099] More specifically, the push rod section 412 has a protrusion on the side facing the crank arm 52, and the protrusion has a push surface 4121.

[0100] like Figure 13 As shown, the mounting part 421 has a first limiting part 423 and a second limiting part 424 protruding from it. The first guide structure 4221 and the second guide structure 4222 are located between the first limiting part 423 and the second limiting part 424, and are combined with... Figure 11 The first end of the transmission rod 41 is provided with a sliding portion 413. Specifically, the sliding portion 413 is provided at the end of the guide rod section 411 away from the push rod section 412. The sliding portion 413 slides in cooperation with the first guide structure 4221 and the second guide structure 4222, and is constrained between the first limiting portion 423 and the second limiting portion 424. By limiting the first limiting portion 423 and the second limiting portion 424, the transmission rod 41 can always be accurately aligned with the first guide structure 4221 and the second guide structure 4222, avoiding misalignment that would prevent the transmission rod 41 from switching between the first position and the second position.

[0101] like Figure 11 As shown, at least one guide groove 4112 is recessed in the side wall of the guide rod section 411, and at least one guide protrusion is protruded in the inner wall of the guide hole 22. The guide protrusion slides in conjunction with the guide groove 4112, which further improves the sliding accuracy of the transmission rod 41 and reduces the deviation.

[0102] like Figure 15 As shown, a guide cylinder 29 protrudes from the output component 2, and a guide hole 22 passes through the guide cylinder 29, which can extend the setting distance of the guide hole 22, improve the sliding stability of the transmission rod 41, and provide sufficient space for the mounting groove 23 for installing the elastic component 43.

[0103] like Figure 13 and Figure 14 As shown, the mounting part 421 is provided with a receiving cavity 4211 and a first buckle 4212. The mounting part 421 engages with the motion mechanism 3 through the receiving cavity 4211 and is engaged with the motion mechanism 3 through the first buckle 4212, thereby achieving a fixed connection between the transmission push block 42 and the motion mechanism 3. Specifically, the mounting part 421 includes a first plate 4214 and two second plates 4215 connected to both ends of the first plate 4214. The first plate 4214 and the two second plates 4215 form a U-shaped structure, which defines the receiving cavity 4211 and engages with the motion mechanism 3. The end of each second plate 4215 away from the first plate 4214 is provided with a first buckle 4212, thereby achieving a firm engagement with the motion mechanism 3 through the first buckle 4212.

[0104] Furthermore, a limiting protrusion 31 is provided on one of the mounting part 421 and the motion mechanism 3, and a second slot 4213 is provided on the other. The limiting protrusion 31 engages with the second slot 4213 to limit the mounting part 421 in the moving direction of the motion mechanism 3, thereby preventing the mounting part 421 and the motion mechanism 3 from sliding relative to each other in the moving direction of the motion mechanism 3, and ensuring that the motion mechanism 3 can drive the transmission push block 42 to move synchronously.

[0105] like Figure 13 As shown, the motion mechanism 3 includes a fixed frame 32, a motion mechanism body 33, a drive mechanism 34, and a gear set 35. The fixed frame 32 is fixedly connected to the mounting chamber 10 by fasteners such as screws. The motion mechanism body 33 is movably connected to the fixed frame 32 and can extend out of the mounting chamber 10 through the motion mechanism baffle 14. The transmission push block 42 is connected to the motion mechanism body 33. The housing of the drive mechanism 34 is fixedly connected to the fixed frame 32. The output end of the drive mechanism 34 is connected to the driving gear of the gear set 35 to drive the driving gear to rotate. The driving gear drives other driven gears to rotate. A transmission rack is provided on the motion mechanism body 33. The transmission rack meshes with the last driven gear to drive the motion mechanism body 33 to extend or retract into the mounting chamber 10 under the drive of the driven gear.

[0106] The aforementioned limiting protrusion 31 is provided on the main body 33 of the motion mechanism to achieve connection with the transmission push block 42. The drive mechanism 34 is exemplarily a rotary motor.

[0107] like Figure 16 and Figure 17 As shown, the output component 2 is provided with a groove 24 and a through channel 25. A third limiting part 26 and a fourth limiting part 27 are protruding from the groove 24 at intervals, forming a limiting region 28. The crank arm 52 extends into this limiting region 28 through the through channel 25. The second end of the transmission rod 41 is located in the groove 24 and partially extends into the limiting region 28 to abut against the crank arm 52. Specifically, the push rod section 412 of the transmission rod 41 partially extends into the limiting region 28 between the third limiting part 26 and the fourth limiting part 27 to abut against the crank arm 52. This ensures that the movement between the push rod section 412 and the crank arm 52 occurs within this limiting region 28, guaranteeing accurate alignment and reliably realizing the flipping opening and closing of the baffle body 51. Simultaneously, it conceals the crank arm 52 and the push rod section 412, preventing the movement engagement position from being exposed externally.

[0108] like Figure 2As shown, the mounting assembly 1 includes a top cover 11, a base 12, and an outer trim panel 13. The base 12 is mounted on the toilet body 200, the top cover 11 is fastened to the base 12, and the top cover 11 defines the aforementioned mounting chamber 10 between the two. The output component 2 is mounted on the top cover 11, and the outer trim panel 13 covers the outside of the top cover 11 and covers the output component 2. Figure 17 The upper cover 11 is provided with an installation port, and a bearing plate protrudes from the inner wall of the installation port. (See attached image) Figure 15 The output component 2 includes a mounting plate 210 and multiple air ducts disposed on the mounting plate 210. One end of each air duct is connected to the input port 21 of the output component 2, and the other end of each air duct forms a port as shown in the figure. Figure 16 The multiple output ports 20 shown are connected to the input port 21 of the functional device 300, so that the sterilizing airflow is input through the input port 21 and then flows out through the multiple output ports 20 to achieve sterilization treatment of the toilet. The mounting plate 210 is also provided with a boss 220. The mounting plate 210 is locked in the mounting opening of the upper cover 11 and placed on the support plate. The boss 220 is locked in the slot formed by the support plate.

[0109] like Figure 12 As shown, a limiting protrusion 53 is provided on the side of the baffle body 51 facing the output port 20, and a limiting groove 230 is recessed on the side of the output component 2 where the output port 20 is located (e.g., Figure 16 As shown), when the baffle body 51 is in the closed state, the limiting protrusion 53 is inserted into the limiting slot 230, which improves the sealing performance of the sealed output port 20 and further reduces the entry of water, dust, foreign objects and other substances into the output port 20.

[0110] like Figure 1 and Figure 4 As shown, the toilet seat assembly 100 also includes a seat 6 and a seat ring 7. Both the seat 6 and the seat ring 7 are movably connected to the mounting assembly 1, specifically rotatably connected to the upper cover 11 of the mounting assembly 1, so as to flip open or close. The outlet 20 is located between the seat 6 and the seat ring 7. When the sterilizing airflow is output through the outlet 20, part of the airflow can fall on the inner wall of the toilet and the extended motion mechanism 3, and part of the airflow can fall on the seat ring 7, thereby achieving sterilization treatment of the seat ring 7.

[0111] like Figure 2 As shown, the toilet also includes an airflow drive unit 400, which is connected to the functional device 300 and is used to generate airflow to blow the functional substance generated by the functional device 300 toward the output unit 2, so that the output unit 2 outputs airflow containing the functional substance, such as bactericidal airflow, deodorizing airflow, and other airflows. For example, the airflow drive unit 400 includes a fan or blower.
