Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of bathroom facilities, in particular to a linkage system, a cover plate assembly of a toilet and the toilet. BACKGROUND

[0002] In some devices, the opening and closing of the baffle for covering the outlet is usually involved to open or cover the outlet at the appropriate time. For example, in a smart toilet with atomization sterilization function, in order to ensure that the atomization range can cover the seat and the inner wall of the toilet, the mist outlet is usually arranged between the seat and the cover plate of the toilet. After the sterilization gas mist generated by the atomization device is sprayed out through the mist outlet, part of it falls on the inner wall of the toilet and part of it falls on the seat, thereby sterilizing the inner wall of the toilet and the seat. However, such an upper mist outlet is prone to water, dust and dirt, thereby affecting the normal operation and sanitary performance of the device. To solve this problem, an outlet baffle is arranged at the mist outlet, and the baffle is opened to allow the atomization gas to be discharged during work, and the baffle is closed to prevent foreign matter from entering in the non-working state. In order to maintain a high atomization efficiency, the fan used by the atomization device of the toilet usually has a small wind power, and if the fan of the atomization device is used, the wind power is not enough to directly blow up the outlet baffle, so it is difficult to realize the automatic opening and closing of the outlet baffle during the sterilization program. If an additional motor is used to control the opening and closing of the baffle, not only the manufacturing cost is increased, but also additional installation space is required for the motor, and the control logic is complicated, and the failure rate of the toilet is increased.

[0003] In the related art, if the movement of the movement mechanism is used to drive the outlet baffle to open or close, the sterilization gas flow can sterilize the inner wall of the toilet and the movement mechanism in the extended state at the same time, but the movement mechanism in the extended state may be in a cleaning working state, at this time, if the outlet baffle is opened to output the sterilization gas flow, the inner wall of the toilet and the movement mechanism cannot be well sterilized, resulting in waste of sterilization material and reduction of overall sterilization efficiency.

[0004] Therefore, there is an urgent need for a linkage system, a cover plate assembly of a toilet and the toilet to solve the above problems in the related art. SUMMARY

It should be understood that the specific embodiments described herein are intended to be merely illustrative of the application and not in limitation thereof. It should also be noted that, for the purpose of brevity of description, only the parts of the drawings that are relevant to the present application are shown.

[0073] In the description of the present application, unless specifically defined and limited otherwise, the terms "connected", "connected to", "fixed", "fixed to" should be interpreted broadly, for example, can be fixed connection, can also be detachable connection, or integral; can be mechanical connection, can also be electrical connection; can be directly connected, can also be indirectly connected through an intermediate medium, can be the internal communication of two elements or the interaction relationship between two elements. For those skilled in the art, the specific meaning of the above terms in the present application can be understood according to the specific circumstances.

[0074] In the present application, unless specifically defined and limited otherwise, "on" or "under" of the first feature to the second feature can include that the first and second features are in direct contact, or that the first and second features are not in direct contact but are in contact through another feature between them. Moreover, "on", "above" and "above" of the first feature to the second feature includes that the first feature is directly above and obliquely above the second feature, or only indicates that the horizontal height of the first feature is higher than that of the second feature. "Below", "below" and "below" of the first feature to the second feature includes that the first feature is directly below and obliquely below the second feature, or only indicates that the horizontal height of the first feature is less than that of the second feature.

In addition, the terms "first" and "second" are only used to distinguish in description and have no special meaning.

[0076] In the present embodiment, the term "and / or" is only a description of the association relationship of the associated objects, which means that there can be three relationships, for example, A and / or B, which can represent the three cases of A alone, A and B together, and B alone. In addition, the character " / " in the present application generally represents an "or" relationship between the front and rear associated objects.

[0077] In the embodiments of the present application, the same reference signs represent the same components, and for the sake of brevity, the detailed description of the same components is omitted in different embodiments.

[0078] As shown in Figure 1 , Figure 2 and Figure 3 , the present embodiment provides a linkage system, comprising an output member 2, a movement mechanism 3 and a linkage assembly 4. Wherein, the output member 2 is provided with an output port 20, and the output port 20 is provided with an openable and closable outlet flap 5; the movement mechanism 3 has a first position, a second position and a third position, and the second position is between the first position and the third position; the linkage assembly 4 is connected between the movement mechanism 3 and the outlet flap 5; when the movement mechanism 3 moves between the second position and the third position, the outlet flap 5 is driven by the linkage assembly 4 to move between the closed state and the open state.

[0079] The linkage system provided by the present embodiment can utilize the kinetic energy of the extension and retraction of the movement mechanism 3 itself as a direct power source for driving the opening and closing of the outlet flap 5 by setting the linkage assembly 4 connecting the movement mechanism 3 and the outlet flap 5. Compared with the scheme of opening the outlet flap 5 by additionally using a motor or an electric control element in the related art, the linkage assembly 4 is a purely mechanical automatic control structure, which not only can simplify the control logic, reduce the failure rate and production cost, but also can save the space for arranging the motor and other elements, improve the space utilization rate, facilitate the miniaturization and thinning design of the product, and provide greater flexibility for the layout of other functional modules.

[0080] By finely dividing the stroke of the movement mechanism 3 into the first position, the second position and the third position, and limiting the opening of the outlet flap 5 by the linkage assembly 4 only when the movement mechanism 3 moves from the second position to the third position, the situation that the corresponding function is opened when the outlet flap 5 is opened when the movement mechanism 3 is in the second position is avoided. Through the cooperation of the output member 2, the movement mechanism 3 and the linkage assembly 4, the outlet flap 5 can be opened and closed within a set period, and the outlet flap 5 can be kept closed outside the set period. When the linkage system is applied in a toilet, the outlet flap 5 can be avoided to be opened in some specific working states, and the use experience is better.

[0081] As shown in Figure 1 and Figure 2As shown, the present embodiment also provides a toilet, which comprises a toilet body 200, a functional device 300 (for example, having a sterilization function, a deodorization function or other functions, etc.) and a cover assembly 100 of the toilet. The cover assembly 100 of the toilet comprises the linkage system described above, and the cover assembly 100 and the functional device 300 are both arranged on the toilet body 200. The cover assembly 100 provided by the present embodiment is arranged above the toilet body 200, and can realize automatic opening and closing of the outlet flap 5 of the toilet without using a motor or other driving member, and can avoid opening the outlet flap 5 when the movement mechanism 3 is in a specific state, thereby improving the efficiency of the functional device 300 and reducing the cost.

[0082] Specifically, the cover assembly 100 of the toilet comprises a mounting assembly 1. The mounting assembly 1 defines a mounting chamber 10. The output member 2 is arranged on the mounting assembly 1 and connected with the functional device 300 of the toilet, and the functional device 300 is used to supply the output member 2 with functional substances. When the outlet flap 5 is opened, the airflow containing the functional substances can be output through the output port 20. The movement mechanism 3 is movably connected to the mounting assembly 1 and has a first position in the mounting chamber 10 and a second position and a third position extending out of the mounting chamber 10. That is, the movement mechanism 3 is located in the mounting chamber 10 when it is in the first position, and the movement mechanism 3 extends out of the mounting chamber 10 when it is in the second position and the third position; when the movement mechanism 3 moves from the second position to the third position, the outlet flap 5 is driven by the linkage assembly 4 to move from the closed state to the open state. During the movement of the movement mechanism 3 extending out of the mounting chamber 10, the movement mechanism 3 sequentially passes through the first position, the second position and the third position. When the movement mechanism 3 extends or retracts, the outlet flap 5 can be driven to move by the linkage assembly 4. Specifically, when the movement mechanism 3 moves from the second position to the third position, the outlet flap 5 is driven by the linkage assembly 4 to move from the closed state to the open state.

[0083] It should be noted that the output port 20 can output air, sterilization mist, plasma, etc., and the present embodiment does not make strict limitations thereon.

[0084] Exemplarily, the functional device 300 described above is a sterilization device of the toilet, which can output sterilization substances so that the sterilization substances are output through the output port of the output member, for example, in the form of spray. Of course, the functional device 300 described above can also be a deodorization device or other device, etc., and the present embodiment only takes the sterilization device as an example for description, and does not limit the functional device 300. The movement mechanism described above comprises a spray gun of the toilet.

[0085] The cover plate assembly 100 and the closestool using the same provided by the embodiment can use the kinetic energy of the movement mechanism 3 itself extending and retracting as a direct power source for driving the opening and closing of the outlet baffle 5 by setting the linkage assembly 4 connecting the movement mechanism 3 and the outlet baffle 5. Compared with the scheme of opening the outlet baffle 5 by additionally using a motor or an electric control element in the related art, the linkage assembly 4 is a pure mechanical automatic control structure, which can not only simplify the control logic of the intelligent closestool, reduce the failure rate and production cost, but also save the space for arranging the motor and other elements, make the space utilization of the cover plate assembly 100 higher, be beneficial to the miniaturization and thinning design of the product, and provide greater flexibility for the layout of other functional modules.

[0086] By finely dividing the stroke of the movement mechanism 3 into the first position, the second position and the third position, and limiting the opening of the outlet baffle 5 by the linkage assembly 4 only when the movement mechanism 3 moves from the second position to the third position, the opening of the outlet baffle 5 for sterilization treatment when the movement mechanism 3 is in the second position is avoided, and it is ensured that the sterilization airflow is output from the output port 20 only when the movement mechanism 3 and the inner wall of the closestool are both in a suitable static state for sterilization. When the second position is the cleaning position of the movement mechanism 3, it is ensured that the outlet baffle 5 is in the closed state when the movement mechanism is in the cleaning working state, and the sterilization airflow is output through the output port 20 only when the movement mechanism 3 continues to extend from the cleaning position to the third position and drives the outlet baffle 5 to open through the linkage assembly 4, so as to realize the sterilization treatment of the inner wall of the closestool and the movement mechanism 3 extending from the installation chamber 10, avoid the waste of sterilization substances in the invalid period (such as the cleaning working state of the movement mechanism 3), and improve the sterilization efficiency. When the movement mechanism 3 moves from the third position to the second position again, the outlet baffle 5 can be driven by the linkage assembly 4 to move to the closed state to cover the output port 20, so as to avoid the pollution caused by the water, dust and foreign matters entering the output element 2 from the output port 20.

[0087] That is, when the user needs to start the sterilization function, the movement mechanism 3 is driven to move from the second position to the third position, and the outlet baffle 5 can be opened synchronously through the linkage assembly 4, so that the functional device 300 can start to work immediately, and the sterilization airflow is output through the output port 20 for sterilization, so as to realize the sterilization treatment of the inner wall of the closestool and the extending part of the movement mechanism 3, and avoid the pollution problem caused by the long-term sterilization of the movement mechanism 3. When the sterilization is finished, the movement mechanism 3 is retracted into the installation chamber 10, and the outlet baffle 5 is automatically closed through the linkage assembly 4 in this process, which can effectively prevent the invasion of foreign matters in the non-working period. Moreover, the linkage assembly 4 can limit the outlet baffle 5 in the closed state to prevent the accidental opening of the outlet baffle 5, so that the outlet baffle 5 can maintain the good sealing protection effect on the output port 20.

[0088] As Figure 2As shown, the mounting assembly 1 is further provided with an openable and closable movement mechanism baffle 14 at the front side of the movement mechanism 3. When the movement mechanism 3 extends out of the mounting chamber 10, the movement mechanism baffle 14 can be pushed open. When the movement mechanism 3 retracts into the mounting chamber 10, the movement mechanism baffle 14 automatically closes under the action of gravity.

[0089] In the embodiment, the first position is the initial position of the movement mechanism 3, the second position is the cleaning position of the movement mechanism 3, and the third position is the limit position of the movement mechanism 3 when extending out of the mounting chamber 10, corresponding to the maximum stroke of the movement mechanism 3.

[0090] As shown in Figure 3 and Figure 4 , it is a schematic view when the movement mechanism 3 is in the second position, and the outlet baffle 5 is in the closed state of covering the output port 20. As shown in Figure 5 and Figure 6 , it is a schematic view when the movement mechanism 3 is in the third position, and the outlet baffle 5 is in the open state of opening the output port 20.

[0091] As shown in Figure 5 and Figure 10 , the outlet baffle 5 includes a baffle body 51 and a toggle arm 52. The first end of the baffle body 51 is rotationally connected with the output member 2 through a rotating shaft, and the toggle arm 52 is connected with the second end of the baffle body 51. In combination with Figure 2 , Figure 3 and Figure 4 , the linkage assembly 4 includes a connecting rod mechanism 41 and a push rod 42. The push rod 42 is slidingly connected with the output member 2, the movement mechanism 3 is movably connected with the first end of the push rod 42 through the connecting rod mechanism 41, and the second end of the push rod 42 is slidingly abutted with the toggle arm 52. When the movement mechanism 3 moves from the second position to the third position, the push rod 42 can be driven to move by the connecting rod mechanism 41, so as to reciprocate between the fourth position and the fifth position, thereby realizing the opening and closing of the outlet baffle 5.

[0092] When the push rod 42 moves from the fourth position to the fifth position, it drives the baffle body 51 to rotate to the open state by pushing the crank arm 52, and when the push rod 42 moves from the fifth position to the fourth position, the baffle body 51 rotates to the closed state under the action of its own gravity to seal the output port 20. Through the connecting rod mechanism 41, the movement of the movement mechanism 3 can be accurately converted into the linear motion of the push rod 42 through the connecting rod mechanism 41, and the connecting rod mechanism 41 has high movement stability and high transmission efficiency. By driving the linear motion of the push rod 42, and the abutment of the end of the push rod 42 and the crank arm 52, the power is effectively transmitted and converted into the rotary motion of the baffle body 51, which ensures that the baffle body 51 can be reliably pried open. Moreover, the automatic reset is realized by using the gravity of the baffle body 51 itself, without the need for any other reset elements, which can simplify the structure, reduce the number of parts, and further reduce the manufacturing cost and assembly complexity.

[0093] Specifically, the sliding direction of the push rod 42 is the vertical direction, and the baffle body 51 rotates around the 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, it pushes down the crank arm 52 through the second end, thereby causing the crank arm 52 to drive the baffle body 51 to flip open, so that the sterilization airflow can smoothly pass through the output port 20 and be output. When the push rod 42 rises from the fifth position to the fourth position, the second end moves away from the crank arm 52, no longer abutting the crank arm 52, and at this time, the baffle body 51 automatically flips to a state of closing the output port 20 under the action of its own gravity. The slidable abutment cooperation between the push rod 42 and the crank arm 52 can adapt to the position change between the two while ensuring that the baffle body 51 can be driven to flip open, avoiding movement jamming.

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

[0095] Optionally, the connecting rod mechanism 41 comprises a first connecting rod 411 and a second connecting rod 412; one end of the first connecting rod 411 is movably connected with the fixed frame 31, and the other end is movably connected with the second connecting rod 412 to form a connecting end 410, and the end of the second connecting rod 412 away from the first connecting rod 411 is movably connected with the fixed frame 31. The connecting end 410 is slidably abutted with the push rod 42, and the moving mechanism body 32 is abutted with or separated from the second connecting rod 412. When the moving mechanism body 32 is abutted with the second connecting rod 412, the two establish a linkage relationship, so that when the moving mechanism 3 is moved from the second position to the third position, the second connecting rod 412 can be driven to move through the abutment with the second connecting rod 412, and the second connecting rod 412 in turn drives the first connecting rod 411 to move, so that the connecting end 410 rises or falls, and the push rod 42 falls to the fifth position with the connecting end 410 to open the outlet baffle 5, or rises to the fourth position to close the outlet baffle 5.

[0096] That is, the abutment or separation of the moving 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 moving mechanism body 32 moves to a specific stroke stage (second position to third position in this embodiment), ensuring that the sterilization function will not be mistakenly started when the moving mechanism 3 is in the cleaning state, effectively avoiding the waste of sterilization substances. Moreover, the connecting rod group composed of the first connecting rod 411, the second connecting rod 412 and the fixed frame 31 can form a stable transmission arm to effectively transmit and convert the pushing force of the moving mechanism body 32, and finally accurately transmit the movement to the push rod 42 through the connecting end 410, ensuring the force transmission efficiency and movement stability, and ensuring that the outlet baffle 5 can be reliably pushed open.

[0097] As shown in Figure 3 , Figure 4 , Figure 5 and Figure 6 , one end of the first connecting rod 411 is hinged with the fixed frame 31, and the other end is hinged with 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 column 311, the guide column 311 is arranged in the strip-shaped hole 4121 and movably cooperates with the strip-shaped hole 4121. Further, the moving mechanism body 32 is provided with a first cooperation part 321, and the second connecting rod 412 is provided with a second cooperation part 4122, the first cooperation part 321 is abutted or separated from the second cooperation part 4122 to realize the opening of the outlet baffle 5 at a specific stroke stage of the moving 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, the first baffle 4123 is protruded on the second connecting rod 412, the second baffle 312 is protruded on the fixing frame 31, and the first elastic member 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 member 43, and the two ends of the first elastic member 43 can be connected to the first baffle 4123 and the second baffle 312 by welding, hooking or other means. A guide protrusion can be provided on the first baffle 4123 and / or the second baffle 312, and the first elastic member 43 is sleeved on the guide protrusion to guide the extension and contraction of the first elastic member 43.

[0103] Exemplarily, the first elastic member 43 is a spring, which is convenient to obtain and can provide sufficient elastic force to reset the connecting rod mechanism 41.

[0104] As shown in Figure 4 and Figure 6 , the connecting end 410 includes a guide portion 4111 protruded on the first connecting rod 411 or the second connecting rod 412, and the guide portion 4111 is provided with a guide plane 4111a and a guide arc surface 4111b connected to each other. The lower end of the push rod 42 can abut against and 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, which can increase the contact area by abutting against the guide plane 4111a, so that the outlet baffle 5 is stably kept in the closed state and cannot be opened, thereby providing effective sealing protection for the outlet 20. When the connecting end 410 of the connecting rod mechanism 41 descends under the drive of the movement mechanism 3, the push rod 42 slides from the guide plane 4111a to the guide arc surface 4111b, and when the push rod 42 is in the fifth position, it abuts against the guide arc surface 4111b. When the movement mechanism 3 is reset, the push rod 42 slides along the guide arc surface 4111b to the guide plane 4111a again. The transition between the guide arc surface 4111b and the guide plane 4111a is smooth, which can reduce the sliding resistance of the push rod 42 and avoid the phenomenon of jamming of the connecting rod mechanism 41 and the push rod 42 during movement, thereby ensuring the smooth opening and closing of the outlet baffle 5.

[0105] In this embodiment, the guide portion 4111 is protruded on the first connecting rod 411, and in other embodiments, the guide portion 4111 can also be protruded on the second connecting rod 412.

[0106] As shown in Figure 2 and Figure 8 , the linkage assembly 4 further includes a second elastic member 44 connected between the output member 2 and the push rod 42. The push rod 42 can be moved from the fourth position to the fifth position under the elastic force of the second elastic member 44 and elastically abut against the connecting rod mechanism 41, thereby realizing the automatic opening of the outlet baffle 5.

[0107] Specifically, referring to Figure 3 , Figure 4 and Figure 8 , at this time, the movement mechanism 3 is in the second position, the outlet baffle 5 is in the closed state, and the push rod 42 is in the fourth position and abuts against the guide plane 4111a under the elastic force of the second elastic member 44. When the movement mechanism 3 moves from the second position to the third position, the connecting end 410 of the connecting rod mechanism 41 is driven to descend, and the push rod 42 slides along the guide plane 4111a to the guide arc surface 4111b under the elastic force of the second elastic member 44. With the connecting end 410 descending to the fifth position, the push rod 42 slides to the state as shown in Figure 5 and Figure 6 .

[0108] As shown in Figure 5 and Figure 6 , at this time, the push rod 42 is in the fifth position and abuts against the guide arc surface 4111b, and the outlet baffle 5 is in the fully open state. The push rod 42 remains in the fifth position under the elastic force of the second elastic member 44 and cannot be moved at will, thereby maintaining the open state of the outlet baffle 5, so that the sterilization gas flow can be continuously output.

[0109] As shown in Figure 8 , the output member 2 is provided with a guide hole 22, and the inner wall of the guide hole 22 is annularly provided with a mounting groove 23; the push rod 42 slidably penetrates the guide hole 22. In combination with Figure 9 , the push rod 42 is annularly provided with a first clamping groove 4211, the first clamping groove 4211 is annularly provided with a stop member 45, and the second elastic member 44 is annularly provided on the push rod 42 and abuts between the bottom wall of the mounting groove 23 and the stop member 45. Specifically, the second elastic member 44 is in a compressed state between the bottom wall of the mounting groove 23 and the stop member 45, and can always provide an elastic force to elastically abut against the guide plane 4111a and the guide arc surface 4111b. The mounting groove 23 and the stop member 45 can improve the mounting stability of the second elastic member 44, and can guide the expansion and contraction of the second elastic member 44, reducing the nonlinear deformation of the second elastic member 44.

[0110] Exemplarily, the second elastic member 44 is a spring, which is convenient to obtain and can provide sufficient elastic force. The stop member 45 can be a ring-shaped clamping spring with an opening, which is clamped into the first clamping groove 4211 through the opening, and is firmly and stably mounted.

[0111] As shown in Figure 9As shown, the push rod 42 comprises a guide rod segment 421 and a push rod segment 422 arranged at an angle, the guide rod segment 421 is in sliding fit with the guide hole 22 of the output member 2, and the push rod segment 422 is provided with a push surface 4221 on one side along the sliding direction of the guide rod segment 421, and the push surface 4221 is used to abut against the toggle arm 52. The guide rod segment 421 is used to guide the vertical sliding of the push rod 42 along the guide hole 22, and the push rod segment 422 is located outside the guide hole 22 and is used to press down the toggle arm 52 through the push surface 4221 under the driving of the guide rod segment 421, so as to drive the flap body 51 to open by the toggle arm 52. Further, when the push surface 4221 presses or moves away from the toggle arm 52, the push surface 4221 and the toggle arm 52 are in sliding abutment fit.

[0112] More specifically, the side of the push rod segment 422 facing the toggle arm 52 is provided with a protrusion, and the protrusion is provided with the push surface 4221.

[0113] Continuing to refer to Figure 9 , the end of the guide rod segment 421 away from the push rod segment 422 is provided with a sliding part 423, and the sliding part 423 can abut against the guide plane 4111a and the guide arc surface 4111b.

[0115] As shown in FIGS. 9 and Figure 12 , a guide cylinder 29 is protruded on the output member 2, and the guide hole 22 penetrates through the guide cylinder 29, which can prolong the setting distance of the guide hole 22, improve the sliding stability of the push rod 42, and has sufficient space to set the mounting groove 23 for mounting the second elastic member 44.

[0116] As shown in FIGS. 9 and Figure 11As shown, the output member 2 is provided with a groove 24 and a through channel 25.

The crank arm 52 extends into the limiting area 28 through the through channel 25, and the second end of the push rod 42 is located in the groove 24 and partially extends into the limiting area 28 to abut against the crank arm 52. Specifically, the abutting push rod segment 422 of the push rod 42 partially extends into the limiting area 28 between the first limiting part 26 and the second limiting part 27 to abut against the crank arm 52, so that the movement cooperation between the abutting push rod segment 422 and the crank arm 52 is performed in the limiting area 28, ensuring that the two can be accurately aligned and reliably realize the opening and closing of the flap body 51. At the same time, the crank arm 52 and the abutting push rod segment 422 can be hidden, avoiding the exposure of the movement cooperation position to the outside.

[0117] As shown in Figure 2 and Figure 13 , the mounting assembly 1 includes an upper cover 11, a base 12, and an outer decorative plate 13.

In combination with , a limiting clamping groove 230 is recessed on the side of the output member 2 where the output port 20 is provided. When the flap body 51 is in the closed state, the limiting protruding strip 53 is clamped into the limiting clamping groove 230 to improve the sealing performance after covering the output port 20, and further reduce the entry of water, dust, foreign matter, etc. into the output port 20.
