Description

Technical Field

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

[0002] In some devices, the opening and closing of a baffle to cover the outlet is often involved, allowing the outlet to be opened or closed at appropriate times. For example, in smart toilets with atomizing sterilization functions, to ensure that the atomization range covers the seat and the inner wall of the toilet, the mist outlet is usually located between the seat and the lid. The sterilizing mist generated by the atomizing device is sprayed out through the mist outlet, with some landing on the inner wall of the toilet and some on the seat, simultaneously sterilizing both. However, this top-mounted mist 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 mist 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. To maintain high atomization efficiency, the atomizing device in the toilet typically uses a relatively weak fan. If the fan used in the atomizing device is insufficient to directly blow up the outlet baffle, it is difficult to achieve automatic opening and closing of the outlet baffle during the sterilization process. Using an additional motor to control the opening and closing of the baffle not only increases manufacturing costs, but also requires additional installation space for the motor, complicates the control logic, and increases the failure rate of the toilet.

[0003] In related technologies, if the movement of the motion mechanism is used to drive the outlet baffle to open or close, the sterilizing airflow can sterilize the inner wall of the toilet while simultaneously sterilizing the extended motion mechanism. However, the motion mechanism may be in a cleaning state when extended. If the outlet baffle is opened to allow the sterilizing airflow to be output at this time, it will not have a good sterilizing effect on the inner wall of the toilet or the motion mechanism, resulting in a waste of sterilizing substances and a reduction in overall sterilization efficiency.

[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 relevant technologies. Summary of the Invention

[0005] The purpose of this invention is to provide a linkage system, a toilet seat assembly, and a toilet that can automatically open and close the outlet baffle during the setting phase, resulting in a better user experience.

[0006] To achieve this objective, the present invention adopts the following technical solution:

[0007] Firstly, a linkage system is provided, including:

[0008] The output component is provided with an output port, and the output port is provided with an openable and closable outlet baffle;

[0009] A motion mechanism having a first position, a second position, and a third position, wherein the second position is located between the first position and the third position;

[0010] A linkage component is connected between the motion mechanism and the outlet baffle;

[0011] When the motion mechanism moves between the second position and the third position, it drives the outlet baffle to move between the closed state and the open state through the linkage component.

[0014] When the push rod moves to the fifth position, it pushes against the crank arm, causing the baffle body to rotate to the open state. When the push rod moves to the fourth position, the baffle body rotates to the closed state under its own gravity.

[0015] As an optional solution to the linkage system provided by the present invention, the motion mechanism includes a fixed frame and a motion mechanism body, wherein the motion mechanism body is movably connected to the fixed frame.

[0016] The linkage mechanism includes a first link and a second link; one end of the first link is movably connected to the fixed frame, and the other end is movably connected to the second link to form a connecting end; the end of the second link away from the first link is movably connected to the fixed frame.

[0017] The connecting end is slidably engaged with the push rod, and the main body of the motion mechanism is engaged with or separated from the second connecting rod.

[0018] As an optional solution to the linkage system provided by the present invention, one end of the first connecting rod is hinged to the fixed frame, and the other end is hinged to the second connecting rod;

[0019] One of the second connecting rod and the fixed frame is provided with a strip hole, and the other is provided with a guide post. The guide post passes through the strip hole and is movably engaged with the strip hole.

[0020] and / or;

[0021] The motion mechanism body is provided with a first mating part, and the second connecting rod is provided with a second mating part. When the motion mechanism body is in the first position, the first mating part and the second mating part are separated.

[0022] When the main body of the motion mechanism moves from the second position to the third position, it pushes against the second mating part through the first mating part.

[0023] As an optional solution to the linkage system provided by the present invention, the linkage component further includes a first elastic element, which is connected between the second link and the fixed frame. Under the elastic force of the first elastic element, the second link pushes the push rod to the fourth position through the connecting end.

[0024] As an optional solution of the linkage system provided by the present invention, the second connecting rod is provided with a first baffle, the fixed frame is provided with a second baffle, and the first elastic member is retractably abutted between the first baffle and the second baffle.

[0025] As an optional solution to the linkage system provided by the present invention, the connecting end includes a guide portion protruding on the first link or the second link, and the guide portion is provided with a connected guide plane and a guide arc surface;

[0026] When the push rod is in the fourth position, it abuts against the guide plane; when the push rod is in the fifth position, it abuts against the guide arc surface.

[0027] And / or,

[0028] The linkage component further includes a second elastic element, which is connected between the output component and the push rod. The push rod can move from the fourth position to the fifth position under the elastic force of the second elastic element and elastically abut against the linkage mechanism.

[0029] As an optional solution of the linkage system provided by the present invention, the push rod includes a guide rod segment and a push rod segment arranged at an angle. The guide rod segment is slidably engaged with the output component. The push rod segment is provided with a push surface on one side along the sliding direction of the guide rod segment. The push surface is used to abut against the crank arm.

[0030] And / or,

[0031] The output component is provided with a groove and a through channel. A first limiting part and a second limiting part are provided in the groove at intervals. A limiting area is formed between the first limiting part and the second limiting part. The crank arm extends into the limiting area through the through channel. The second end of the push rod is located in the groove and partially extends into the limiting area to abut against the crank arm.

[0032] Secondly, a toilet seat assembly is provided, including a mounting assembly and a linkage system as described above;

[0033] The mounting assembly defines a mounting chamber; the output member is disposed on the mounting assembly; the motion mechanism is movably connected to the mounting assembly; the motion mechanism is located within the mounting chamber when in the first position; and extends out of the mounting chamber when in the second position and the second position.

[0034] When the motion mechanism moves from the second position to the third position, the linkage component drives the outlet baffle to move from the closed state to the open state.

[0035] As an optional embodiment of the toilet seat assembly provided by the present invention, the toilet seat assembly further includes a cover and a seat ring, both of which are movably connected to the mounting assembly, and the outlet is located between the cover and the seat ring.

[0036] Thirdly, a toilet is provided, including a toilet body, a functional device, and a toilet seat assembly as described above.

[0037] Both the lid assembly and the functional device are located on the toilet body. The functional device is connected to the output component of the lid assembly and is used to introduce functional substances into the output component.

[0038] The beneficial effects of this invention are:

[0039] This invention provides a linkage system, a toilet seat assembly, and a toilet using the same assembly. By setting a linkage assembly 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. Compared to related technologies that use additional motors or electronic control components to open the outlet baffle, this linkage assembly is a purely mechanical automatic control structure. This not only simplifies the control logic, reduces the failure rate and production costs, but also saves space for arranging motors and other components, improving space utilization. This facilitates miniaturization and thinner design of the product and provides greater flexibility for the layout of other functional modules.

[0040] By precisely dividing the travel of the motion mechanism into a first position, a second position, and a third position, and limiting the opening of the outlet baffle to only when the motion mechanism moves from the second position to the third position, the system avoids the situation where opening the outlet baffle while the motion mechanism is in the second position would activate the corresponding function. Through the cooperation of this output component, motion mechanism, and linkage component, the outlet baffle can be opened and closed within a set period, and kept closed outside the set period. When this linkage system is applied to a toilet, it can prevent the outlet baffle from opening under certain operating conditions, resulting in a better user experience. Attached Figure Description

[0072] 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 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, and not all of the structures.

[0073] In the description of this invention, 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 invention based on the specific circumstances.

[0074] 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.

[0075] 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 the present invention. In addition, the terms "first" and "second" are used only for distinction in description and have no special meaning.

[0076] 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.

[0077] In the embodiments of the present invention, 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.

[0078] like Figure 1 , Figure 2 as well as Figure 3 As shown, this embodiment provides a linkage system, including an output component 2, a motion mechanism 3, and a linkage component 4. The output component 2 has an output port 20, and an openable / closable outlet baffle 5 is provided at the output port 20. The motion mechanism 3 has a first position, a second position, and a third position, with the second position located between the first and third positions. The linkage component 4 connects the motion mechanism 3 and the outlet baffle 5. When the motion mechanism 3 moves between the second and third positions, the linkage component 4 drives the outlet baffle 5 to move between a closed state and an open state.

[0079] The linkage system provided in this embodiment, by setting a linkage component 4 connecting the motion mechanism 3 and the outlet baffle 5, can utilize the kinetic energy of the motion mechanism 3 itself during extension and retraction as a direct power source to drive the opening and closing of the outlet baffle 5. Compared with the related technology scheme that additionally uses a motor or electronic control components to open the outlet baffle 5, this linkage component 4 is a purely mechanical automatic control structure, which not only simplifies the control logic, reduces the failure rate and production cost, but also saves space for arranging motors and other components, improves space utilization, facilitates the miniaturization and thinning of the product design, and provides greater flexibility for the layout of other functional modules.

[0080] By precisely dividing the stroke of the motion mechanism 3 into a first position, a second position, and a third position, and limiting the opening of the outlet baffle 5 to only when the motion mechanism 3 moves from the second position to the third position, the situation where opening the outlet baffle 5 while the motion mechanism 3 is in the second position would activate the corresponding function is avoided. Through the cooperation of the output component 2, the motion mechanism 3, and the linkage component 4, the outlet baffle 5 can be opened and closed within a set period, and kept closed outside the set period. When this linkage system is applied to a toilet, it can prevent the outlet baffle 5 from opening under certain specific operating conditions, resulting in a better user experience.

[0081] like Figure 1 and Figure 2As shown, this embodiment also provides a toilet, including a toilet body 200, a functional device 300 (e.g., having sterilization, deodorization, or other functions), and a toilet seat assembly 100. The toilet seat assembly 100 includes the aforementioned linkage system, and 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 toilet outlet baffle 5 without using a motor or other driving components. It also prevents the outlet baffle 5 from opening when the motion mechanism 3 is in a specific state, improving the efficiency of the functional device 300 and reducing costs.

[0082] Specifically, the toilet seat assembly 100 includes a mounting assembly 1. The mounting assembly 1 defines a mounting chamber 10. An output member 2 is disposed on the mounting assembly 1 and connected to a functional device 300 of the toilet, which is used to introduce a functional substance into the output member 2. When the outlet baffle 5 is open, an airflow containing the functional substance can be output through the outlet 20. A motion mechanism 3 is movably connected to the mounting assembly 1 and has a first position located within the mounting chamber 10 and a second and third position extending out of the mounting chamber 10. That is, when the motion mechanism 3 is in the first position, it is located within the mounting chamber 10; when the motion mechanism 3 is in the second and third positions, it extends out of the mounting chamber 10; when the motion mechanism 3 moves from the second position to the third position, it drives the outlet baffle 5 from a closed state to an open state via a linkage assembly 4. During the extension process from the mounting chamber 10, the motion mechanism 3 sequentially passes through the first, second, and third positions. When the motion mechanism 3 extends or retracts, it can drive the outlet baffle 5 to move via the linkage assembly 4. Specifically, when the motion mechanism 3 moves from the second position to the third position, it drives the outlet baffle 5 from the closed state to the open state through the linkage component 4.

[0083] 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.

[0084] 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 includes the toilet spray gun.

[0085] The lid assembly 100 and the toilet using the lid assembly 100 provided in this embodiment, by setting a linkage component 4 connecting the motion mechanism 3 and the outlet baffle 5, can utilize the kinetic energy of the motion mechanism 3 itself as a direct power source to drive the opening and closing of the outlet baffle 5. Compared with the related technology that uses an additional motor or electronic control component to open the outlet baffle 5, this linkage component 4 is a purely mechanical automatic control structure, which not only simplifies the control logic of the smart toilet, reduces the failure rate and production cost, but also saves space for arranging components such as motors, making the internal space utilization of the lid assembly 100 more efficient, which is conducive to the miniaturization and thinning design of the product, and also provides greater flexibility for the layout of other functional modules.

[0086] By precisely dividing the stroke of the motion mechanism 3 into a first position, a second position, and a third position, and limiting the opening of the outlet baffle 5 via the linkage component 4 only when the motion mechanism 3 moves from the second position to the third position, the situation where the outlet baffle 5 opens for sterilization when the motion mechanism 3 is in the second position is avoided. This ensures that the sterilizing airflow is only output from the outlet 20 when both the motion mechanism 3 and the inner wall of the toilet are in a suitable static state for sterilization. When the second position is the cleaning position of the motion mechanism 3, the outlet baffle 5 is kept closed while the motion mechanism is in the cleaning working state. Only when the motion mechanism 3 continues to extend from the cleaning position until it moves to the third position will the outlet baffle 5 open via the linkage component 4, allowing the sterilizing airflow to be output through the outlet 20. This achieves sterilization of the inner wall of the toilet and the motion mechanism 3 extending out of the installation chamber 10, avoiding the loss of sterilizing substances during ineffective periods (such as when the motion mechanism 3 is in the cleaning working state), and improving sterilization efficiency. When the motion mechanism 3 moves from the third position back to the second position, it can drive the outlet baffle 5 to move to the closed state through the linkage component 4 to cover the output port 20 and prevent water, dust and foreign objects from entering the output component 2 from the output port 20 and causing pollution.

[0087] That is, when the user needs to activate the sterilization function, the drive mechanism 3 moves from the second position to the third position, and the outlet baffle 5 is opened simultaneously through the linkage component 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 protruding part of the drive mechanism 3, avoiding the problem of contamination caused by the drive mechanism 3 not being sterilized for a long time. When sterilization is finished, the control mechanism 3 retracts into the installation chamber 10. During this process, the outlet baffle 5 is automatically closed through the linkage component 4, which can effectively prevent foreign objects from entering during non-working periods. Furthermore, the linkage component 4 can 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.

[0088] like Figure 2As 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.

[0089] Specifically, in this embodiment, the first position is the initial position of the motion mechanism 3, the second position is the cleaning position of the motion mechanism 3, and the third position is the limit position when the motion mechanism 3 extends out of the installation chamber 10, corresponding to the maximum stroke of the motion mechanism 3.

[0090] like Figure 3 and Figure 4 The diagram shows the motion mechanism 3 in its second position, at which point the outlet baffle 5 is in a closed state, covering the output port 20. Figure 5 and Figure 6 The diagram shown is a schematic of the motion mechanism 3 in the third position, at which time the outlet baffle 5 is in the open state of the output port 20.

[0091] like Figure 5 and Figure 10 As shown, the outlet baffle 5 includes a baffle body 51 and a crank arm 52. The first end of the baffle body 51 is rotatably connected to the output component 2 via a rotating shaft, and the crank arm 52 is connected to the second end of the baffle body 51. Figure 2 , Figure 3 as well as Figure 4 The linkage component 4 includes a linkage mechanism 41 and a push rod 42. The push rod 42 is slidably engaged with the output component 2. The motion mechanism 3 is movably engaged with the first end of the push rod 42 via the linkage mechanism 41, and the second end of the push rod 42 is slidably abutted against the crank arm 52. When the motion mechanism 3 moves from the second position to the third position, it can drive the push rod 42 to move via the linkage mechanism 41, causing the push rod 42 to reciprocate between the fourth and fifth positions, thereby driving the outlet baffle 5 to flip open or close.

[0092] When push rod 42 moves from the fourth position to the fifth position, it drives the baffle body 51 to rotate to the open state via the push arm 52. When push rod 42 moves from the fifth position to the fourth position, the baffle body 51 rotates to the closed state under its own gravity to seal the output port 20. Through the linkage mechanism 41, the motion of the motion mechanism 3 can be accurately converted into the linear motion of push rod 42, and the linkage mechanism 41 has high motion stability and high transmission efficiency. By driving the linear motion of push rod 42 and the contact between the end of push rod 42 and the crank arm 52, the power is effectively transmitted and converted into the rotational motion of baffle body 51, ensuring that baffle body 51 can be reliably pushed open. Furthermore, the baffle body 51 achieves automatic reset by its own gravity, 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.

[0093] Specifically, the push rod 42 slides vertically, and the baffle body 51 rotates around a horizontal axis to open and close the output port 20. The second end of the push rod 42 is located above the crank arm 52, and the fourth position of the push rod 42 is higher than the fifth position. When the push rod 42 slides from the fourth position to the fifth position, its second end presses down against the crank arm 52, causing the crank arm 52 to rotate and open the baffle body 51, allowing the sterilizing airflow to pass smoothly through the output port 20. When the push rod 42 rises from the fifth position back to the fourth 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 rotates to the closed output port 20 state under its own gravity. The sliding contact between the push rod 42 and the crank arm 52 ensures that the baffle body 51 can be driven to rotate and open while adapting to changes in their positions, avoiding jamming during movement.

[0094] like Figure 3 and Figure 7 As shown, the motion mechanism 3 includes a fixed frame 31, a motion mechanism body 32, a drive mechanism 33, and a gear set 34. The fixed frame 31 is located inside the mounting chamber 10 and is fixedly connected to the mounting assembly 1 by screws or other fasteners. The motion mechanism body 32 is movably connected to the fixed frame 31 and can extend out of the mounting chamber 10 through the motion mechanism baffle 14. The housing of the drive mechanism 33 is fixedly connected to the fixed frame 31. The output end of the drive mechanism 33 is connected to the driving gear of the gear set 34 to drive the driving gear to rotate. The driving gear drives other driven gears to rotate. The motion mechanism body 32 is provided with a transmission rack 322, which meshes with the last driven gear to drive the motion mechanism body 32 to extend or retract into the mounting chamber 10 under the drive of the driven gear. Furthermore, the fixed frame 31 is also provided with a guide rail structure, and the motion mechanism body 32 slides with the guide rail structure to precisely guide its movement. Exemplarily, the drive mechanism 33 includes a drive motor.

[0095] Optionally, the linkage mechanism 41 includes a first link 411 and a second link 412. One end of the first link 411 is movably connected to the fixed frame 31, and the other end is movably connected to the second link 412 to form a connecting end 410. The end of the second link 412 away from the first link 411 is movably connected to the fixed frame 31. The connecting end 410 and the push rod 42 are slidably engaged, and the motion mechanism body 32 abuts against or separates from the second link 412. When the motion mechanism body 32 abuts against the second link 412, the two establish a linkage relationship, so that when the motion mechanism 3 moves from the second position to the third position, it can drive the second link 412 to move through the abutment with the second link 412. The second link 412 then drives the first link 411 to move, so that the connecting end 410 rises or falls. The push rod 42 falls with the connecting end 410 to the fifth position to open the outlet baffle 5, or rises to the fourth position to close the outlet baffle 5.

[0096] That is, the contact or separation of the motion mechanism body 32 and the second connecting rod 412 forms a mechanical trigger switch, so that the opening of the outlet baffle 5 is only triggered when the motion mechanism body 32 moves to a specific stroke stage (the second position to the third position in this embodiment), ensuring that the sterilization function will not be accidentally activated when the motion mechanism 3 is in the cleaning working state, effectively avoiding the waste of sterilization substances. In addition, the linkage group composed of the first connecting rod 411, the second connecting rod 412 and the fixed frame 31 can form a stable transmission arm, effectively transmitting and converting the thrust of the motion mechanism body 32, and finally accurately transmitting the motion to the push rod 42 through the connecting end 410, ensuring the efficiency of force transmission and the stability of motion, and ensuring that the outlet baffle 5 can be reliably pushed open.

[0097] like Figure 3 , Figure 4 , Figure 5 as well as Figure 6 As shown, one end of the first connecting rod 411 is hinged to the fixed frame 31, and the other end is hinged to the second connecting rod 412. One of the second connecting rod 412 and the fixed frame 31 is provided with a strip-shaped hole 4121, and the other is provided with a guide post 311. The guide post 311 passes through the strip-shaped hole 4121 and is movably engaged with it. Furthermore, the motion mechanism body 32 is provided with a first mating part 321, and the second connecting rod 412 has a protruding second mating part 4122. The first mating part 321 and the second mating part 4122 abut or separate, realizing the opening of the outlet baffle 5 during a specific stroke stage of the motion mechanism 3.

[0098] In this embodiment, a strip-shaped hole 4121 is provided on the second connecting rod 412, and a guide post 311 is provided on the fixing frame 31. Of course, in other embodiments, a guide post 311 can also be provided on the second connecting rod 412, and a strip-shaped hole 4121 can be provided on the fixing frame 31.

[0099] Specifically, when the motion mechanism body 32 is in the first position, the first mating part 321 and the second mating part 4122 are separated. As the motion mechanism 3 moves from the first position to the second position, it moves the first mating part 321 closer to the second mating part 4122. When it reaches the second position, the first mating part 321 just touches the second mating part 4122. Then, the motion mechanism 3 continues to move from the second position to the third position. During this process, the first mating part 321 pushes against the second mating part 4122, thereby driving the second connecting rod 412 to move. When the second connecting rod 412 moves, it slides and rotates with the guide post 311 through the slot 4121. The second connecting rod 412 and the first connecting rod 411 rotate relative to each other, causing the connecting end 410 to descend. This causes the push rod 42, which is in contact with the connecting end 410, to descend from the fourth position to the fifth position, driving the baffle body 51 to open the output port 20 by pressing down the crank arm 52.

[0100] More specifically, a first hinge post 313 protrudes from the fixed frame 31. One end of the first connecting rod 411 is hinged to the first hinge post 313 through a hinge hole. The other end of the first connecting rod 411 is provided with a second hinge post 4112, which is hinged to the second hinge post 4112 through a hinge hole. The strip hole 4121 and the second mating part 4122 are both located at the end of the second connecting rod 412 away from the first connecting rod 411. The first mating part 321 is a cylindrical structure protruding from the motion mechanism body 32.

[0101] like Figure 3 and Figure 7 As shown, the linkage assembly 4 also includes a first elastic element 43, which is connected between the second link 412 and the fixed frame 31. When the motion mechanism 3 moves from the second position to the third position to open the outlet baffle 5, the second link 412 compresses the first elastic element 43 under the drive of the motion mechanism 3, so that the first elastic element 43 stores energy. When the motion mechanism 3 moves from the third position to the second position to close the outlet baffle 5, the second link 412 resets under the elastic force of the first elastic element 43, and pushes the push rod 42 to the fourth position through the connecting end 410, so that the outlet baffle 5 closes under its own gravity.

[0102] Specifically, a first baffle 4123 protrudes from the second connecting rod 412, and a second baffle 312 protrudes from the fixing frame 31. The first elastic element 43 is telescopically abutted between the first baffle 4123 and the second baffle 312. The first baffle 4123 and the second baffle 312 provide a mounting base for the first elastic element 43. The two ends of the first elastic element 43 can be connected to the first baffle 4123 and the second baffle 312 by welding, hook connection, or other means. Guide protrusions can be provided on the first baffle 4123 and / or the second baffle 312, and the first elastic element 43 is sleeved on the guide protrusions to guide the telescopic movement of the first elastic element 43.

[0103] For example, the first elastic element 43 is a spring, which is readily available and can provide sufficient elastic force to reset the linkage mechanism 41.

[0104] like Figure 4 and Figure 6 As shown, the connecting end 410 includes a guide portion 4111 protruding from the first connecting rod 411 or the second connecting rod 412. The guide portion 4111 is provided with a connected guide plane 4111a and a guide arc surface 4111b. The lower end of the push rod 42 can abut against the guide plane 4111a and the guide arc surface 4111b, and can slide along the guide plane 4111a and the guide arc surface 4111b. When the push rod 42 is in the fourth position, it abuts against the guide plane 4111a. Specifically, the bottom surface of the push rod 42 is a plane. This plane, by abutting against the guide plane 4111a, can increase the contact area, so that the outlet baffle 5 is stably kept in the closed state and will not open, providing effective sealing protection for the output port 20. When the motion mechanism 3 drives the connecting end 410 of the linkage mechanism 41 to descend, the push rod 42 slides from the guide plane 4111a to the guide arc surface 4111b. When the push rod 42 is in the fifth position, it abuts against the guide arc surface 4111b. When the motion mechanism 3 resets, the push rod 42 slides back onto the guide plane 4111a along the guide arc surface 4111b. The smooth transition between the guide arc surface 4111b and the guide plane 4111a reduces the resistance when the push rod 42 slides, avoids jamming between the linkage mechanism 41 and the push rod 42, and ensures smooth opening and closing of the outlet baffle 5.

[0105] In this embodiment, the guide portion 4111 protrudes from the first connecting rod 411. In other embodiments, the guide portion 4111 may also protrude from the second connecting rod 412.

[0106] like Figure 2 and Figure 8 As shown, the linkage component 4 also includes a second elastic element 44, which is connected between the output component 2 and the push rod 42. The push rod 42 can move from the fourth position to the fifth position under the elastic force of the second elastic element 44 and elastically abut against the linkage mechanism 41 to realize the automatic opening of the outlet baffle 5.

[0107] Specifically, see Figure 3 , Figure 4 as well as Figure 8 At this time, the motion mechanism 3 is in the second position, the outlet baffle 5 is closed, and the push rod 42 is in the fourth position, abutting against the guide plane 4111a under the elastic force of the second elastic element 44. When the motion mechanism 3 moves from the second position to the third position, it drives the connecting end 410 of the linkage mechanism 41 to descend. Under the elastic force of the second elastic element 44, the push rod 42 slides along the guide plane 4111a to the guide arc surface 4111b, and descends with the connecting end 410 to the fifth position, until the push rod 42 slides to the fifth position. Figure 5 and Figure 6 The state shown.

[0108] like Figure 5 and Figure 6 As shown, push rod 42 is in the fifth position at this time, abutting against the guide arc surface 4111b, and the outlet baffle 5 is in a fully open state. Push rod 42 is held in the fifth position by the elastic force of the second elastic element 44 and will not move arbitrarily, thereby maintaining the open state of the outlet baffle 5 and allowing the sterilizing airflow to be continuously output.

[0109] like Figure 8 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 push rod 42 slidably passes through the guide hole 22. Combined with... Figure 9 The push rod 42 has a first groove 4211 on its upper ring, and a stop 45 is engaged in the first groove 4211. The second elastic member 44 is telescopically sleeved on the push rod 42 and abuts against the bottom wall of the mounting groove 23 and the stop 45. Specifically, the second elastic member 44 is in a compressed state between the bottom wall of the mounting groove 23 and the stop 45, and can always provide elastic force to elastically abut against the guide plane 4111a and the guide arc surface 4111b. The mounting groove 23 and the stop 45 can improve the installation stability of the second elastic member 44 and guide the extension and retraction of the second elastic member 44, reducing the nonlinear deformation of the second elastic member 44.

[0110] For example, the second elastic element 44 is a spring, which is readily available and can provide sufficient elastic force. The stop element 45 can be an annular retaining ring with an opening, which engages with the first retaining groove 4211 through the opening for a secure and reliable installation.

[0111] like Figure 9As shown, the push rod 42 includes a guide rod segment 421 and a push rod segment 422 arranged at an angle. The guide rod segment 421 is slidably engaged with the guide hole 22 of the output component 2. The push rod segment 422 has a push surface 4221 on one side along the sliding direction of the guide rod segment 421, which abuts against the crank arm 52. The guide rod segment 421 guides the push rod 42 to slide vertically along the guide hole 22. The push rod segment 422 is located outside the guide hole 22 and is used to press down the crank arm 52 through the push surface 4221 under the drive of the guide rod segment 421, thereby causing the baffle body 51 to flip open through the crank arm 52. Furthermore, when the push surface 4221 is pressed down or moves away from the crank arm 52, the push surface 4221 and the crank arm 52 are in a sliding abutment engagement.

[0112] More specifically, the push rod section 422 has a protrusion on the side facing the crank arm 52, and the protrusion has a push surface 4221.

[0113] Continue reading Figure 9 The guide rod segment 421 has a sliding part 423 protruding from one end away from the push rod segment 422. The sliding part 423 can abut against the guide plane 4111a and the guide arc surface 4111b.

[0114] Such as 9 and Figure 11 As shown in the figure, at least one guide groove 4212 is recessed in the side wall of the guide rod section 421, 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 4212 to further improve the sliding accuracy of the push rod 42 and reduce the deviation.

[0115] like Figure 12 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 push rod 42, and provide sufficient space to set the mounting groove 23 for installing the second elastic element 44.

[0116] like Figure 11As shown, the output component 2 is provided with a groove 24 and a through channel 25. A first limiting part 26 and a second limiting part 27 are provided at intervals within the groove 24, forming a limiting region 28 between the first limiting part 26 and the second limiting part 27. The crank arm 52 extends into this limiting region 28 through the through channel 25. The second end of the push rod 42 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 422 of the push rod 42 partially extends into the limiting region 28 between the first limiting part 26 and the second limiting part 27 to abut against the crank arm 52. This ensures that the movement between the push rod section 422 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 422, preventing the movement engagement position from being exposed externally.

[0117] like Figure 2 and Figure 13 As 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, and the top cover 11 is fastened to the base 12, defining the aforementioned mounting chamber 10 between the top cover 11 and the base 12. 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. Specifically, the top cover 11 is provided with a mounting opening, and a ring of support plate protrudes from the inner wall of the mounting opening. See [reference needed]. Figure 12 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 11 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.

[0118] like Figure 10 As shown, a limit protrusion 53 is provided on the side of the baffle body 51 facing the output port 20, combined with... Figure 11 A limiting groove 230 is recessed on one side of the output port 20 of the output component 2. When the baffle body 51 is in the closed state, the limiting protrusion 53 is inserted into the limiting groove 230 to improve the sealing performance after the output port 20 is covered, and further reduce the entry of water, dust, foreign objects and other substances into the output port 20.

[0119] like Figure 2 and Figure 13As 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.

[0120] like Figure 13 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.
