Description

Technical Field

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

[0002] Currently, in smart toilets equipped with atomizing sterilization functions, the atomizing device is usually located below the seat. Utilizing the downward diffusion of mist, it can quickly create a sterilizing mist environment within the toilet bowl. However, because the density of atomized particles is higher than that of air, they tend to settle naturally in the air. This makes it difficult for the mist to rise effectively and fully cover the seat surface during atomization, resulting in poor sterilization of the toilet seat.

[0003] To address the aforementioned issues, related technologies employ a method that tilts the mist outlet towards the center of the seat ring at a certain angle, while simultaneously increasing the fan speed. This guides the sterilizing mist towards the seat ring area, thereby increasing the amount of mist falling onto the seat ring surface and achieving a sterilizing and disinfecting effect.

[0004] In the above technical solution, although there will be a certain amount of mist falling on the seat ring, only the local area directly opposite the mist outlet can achieve good mist coverage and sterilization effect. The mist distribution in other areas of the seat ring is uneven, the sterilization rate is low, and it is impossible to achieve uniform and effective sterilization of the entire seat ring.

[0005] Therefore, there is an urgent need for a toilet seat assembly, a toilet, and a toilet sterilization control method to solve the aforementioned problems in related technologies. Summary of the Invention

[0006] The purpose of this invention is to provide a toilet seat assembly, a toilet, and a toilet sterilization control method, which can simultaneously sterilize and disinfect the inner wall and seat of the toilet, and can increase the amount and uniformity of mist on the toilet seat, thereby improving the sterilization effect.

[0007] To achieve this objective, the present invention adopts the following technical solution:

[0008] In a first aspect, a toilet seat assembly is provided, comprising:

[0009] Seat ring;

[0010] A cover plate is movably disposed above the seat ring;

[0011] An air outlet is provided with an air inlet and at least one air outlet. The air inlet is configured to be connected to the toilet's sterilization device for introducing the sterilization airflow output by the sterilization device. The air outlet is located between the toilet seat and the toilet seat.

[0012] There is a gap between the cover plate and the seat ring that communicates with the air outlet. The cover plate is provided with an outer baffle along its outer periphery. The gap between the front end of the outer baffle and the seat ring is greater than the gap between the rear end of the outer baffle and the seat ring.

[0013] As an optional solution for the toilet seat assembly provided by the present invention, the gap between the outer edge and the seat ring includes a first guide gap and a second guide gap, wherein the second guide gap is located at the end of the first guide gap away from the air outlet;

[0014] The vertical dimension of the first guide gap is consistent along the direction away from the air outlet;

[0015] The vertical dimension of the second guide gap gradually increases in the direction away from the first guide gap.

[0016] As an optional embodiment of the toilet seat assembly provided by the present invention, the maximum dimension of the first guide gap along the front-to-back direction of the toilet is L1, and the maximum dimension of the second guide gap along the front-to-back direction of the toilet is L2.

[0017] The value of L2 / (L1+L2) ranges from 0.15 to 0.35.

[0018] As an optional embodiment of the toilet seat assembly provided by the present invention, the vertical dimension of the first guide gap is H1, the minimum vertical dimension of the second guide gap is H2, and the maximum vertical dimension of the second guide gap is H3.

[0019] Where H2 is greater than or equal to H1, the value of H1 is in the range of 0.4mm to 0.8mm; the value of H2 is in the range of 0.4mm to 0.8mm; and the value of H3 is in the range of 3mm to 5mm.

[0020] As an optional solution for the toilet seat assembly provided by the present invention, the air outlet is provided in multiple ways, including a first air outlet and a second air outlet and a third air outlet respectively disposed on both sides of the first air outlet.

[0021] The first air outlet extends along the front-to-back direction of the toilet;

[0022] Along the direction from the rear end to the front end of the toilet, the second air outlet and the third air outlet gradually extend in a direction away from the first air outlet;

[0023] And / or,

[0024] The air outlet is oriented with the airflow direction facing upward relative to the horizontal plane.

[0025] As an optional solution for the toilet seat assembly provided by the present invention, the included angle between the second air outlet and the first air outlet is α, and the value of α ranges from 30° to 45°.

[0026] And / or,

[0027] The angle between the third air outlet and the first air outlet is β, and the value of β ranges from 30° to 45°.

[0028] And / or,

[0029] The angle between the air outlet's air outlet direction and the horizontal plane is γ, and the value of γ ranges from 3° to 5°.

[0030] And / or, the first air outlet is located at the center of the toilet seat assembly, and the second air outlet and the third air outlet are arranged in a mirror image symmetrically relative to the first air outlet.

[0031] As an optional embodiment of the toilet seat assembly provided by the present invention, the toilet seat assembly further includes an installation structure.

[0032] The seat ring, the cover plate, and the air outlet are all connected to the mounting structure, which is provided with an air inlet channel; the air inlet is connected to the sterilization device through the air inlet channel.

[0033] As an optional solution for the toilet seat assembly provided by the present invention, the mounting structure includes an upper cover, a base, and an outer decorative panel. The upper cover is fastened to the base and an mounting chamber is formed between the upper cover and the base.

[0034] The upper cover includes a first plate segment, a second plate segment, and a third plate segment that are bent and connected in sequence.

[0035] The air outlet is located on the top cover, and the outer trim panel is located on the first panel segment and covers the air outlet. The first panel segment, the second panel segment, the third panel segment, and the seat ring are arranged sequentially from the rear end to the front end of the toilet. The cover plate is located on the front side of the outer trim panel and there is an air guiding gap between it and the third panel segment. The air outlet blows airflow between the cover plate and the seat ring through the air guiding gap.

[0036] In a second aspect, a toilet is provided, including a toilet body, a sterilization device, and a toilet seat assembly as described above.

[0037] Both the toilet seat assembly and the sterilization device are located on the toilet body, and the air inlet of the air outlet of the toilet seat assembly is connected to the sterilization device.

[0038] Thirdly, a toilet sterilization control method is provided, which uses a toilet as described above for control. The toilet also includes an airflow drive component, and the sterilizing substance generated by the sterilization device is delivered to the air outlet through the airflow drive component.

[0039] The toilet sterilization control method includes:

[0040] Control the sterilization device to start;

[0041] The airflow drive is controlled to operate at a first rotation speed for a first preset duration;

[0042] The airflow drive is controlled to operate at a second rotation speed for a second preset duration;

[0043] Wherein, the first rotational speed is greater than the second rotational speed.

[0044] The beneficial effects of this invention are:

[0045] This invention provides a toilet seat assembly and a toilet using the same assembly. The sterilizing airflow from the sterilization device is output through the air outlet of the air outlet component. By positioning the air outlet between the seat and the toilet seat, the sterilizing airflow can be output between the two surfaces. A portion of the sterilizing airflow falls onto the inner wall of the toilet body under gravity, sterilizing the inner wall, while another portion falls onto the toilet seat, sterilizing it. Because the gap between the front end of the outer edge of the seat and the toilet seat is larger than the gap between the rear end of the outer edge of the seat and the toilet seat, a gradually narrowing drainage channel (wider at the front and narrower at the back) can be formed between the toilet seat and the outer edge of the seat. When the sterilizing airflow (such as the sterilizing mist generated by atomization) enters the narrowing airflow channel (wider at the front and narrower at the back) from the air outlet, according to the principles of fluid mechanics, the airflow will naturally converge and accelerate towards the area with less flow resistance and more space. Therefore, the change in this gap can actively guide the sterilizing airflow to the front area of ​​the seat ring with a larger gap, so that more sterilizing airflow flows out from the front. This ensures that even if the front of the seat ring is far from the air outlet, it can still obtain sufficient and concentrated sterilizing airflow coverage, thereby significantly improving the sterilization effect of the front area of ​​the seat ring, which is the most critical and has the closest contact with the human body.

[0046] Compared with existing technologies that rely solely on fan speed and mist outlet angle, resulting in mist concentration in localized areas, the cover plate assembly of this invention achieves automatic airflow distribution. The larger gap between the front end of the cover plate's outer edge and the seat ring ensures an effective supply of sterilizing airflow to the front area of ​​the seat ring, allowing more sterilizing airflow to flow out from the front end. The smaller gap at the rear end of the cover plate's outer edge prevents excessive loss of sterilizing airflow from this gap, enabling the sterilizing airflow to diffuse more evenly and adhere to the entire upper surface of the seat ring, eliminating sterilization dead zones and fundamentally overcoming the problem of only ensuring sterilization effects in localized areas, thus effectively improving the sterilization effect.

[0047] In addition, the toilet seat assembly can increase the amount and uniformity of mist on the seat by simply placing the air outlet between the seat and the seat ring and combining the gap variation between the outer edge of the seat and the seat ring. It does not require a complicated structural design, which can reduce costs while ensuring the sterilization effect and avoid the problems of high failure rate caused by complex structures.

[0048] This invention also provides a toilet sterilization control method, applied to the aforementioned toilet. This control method uses time-series control of the airflow drive component. In the initial sterilization stage, the airflow drive component operates at a higher initial speed, utilizing the powerful kinetic energy generated by the high-speed airflow to rapidly and forcefully deliver the sterilizing substance to areas farther from the air outlet, such as the front of the seat. This effectively overcomes the problem of early settling of mist due to its own weight, ensuring initial effective coverage of the entire sterilization area, especially key distant locations (including the front area of ​​the seat). In the later sterilization stage, the airflow drive component is switched to a lower second speed. In this stage, the airflow kinetic energy is reduced, and the dispersion of the sterilizing substance is gentler and slower. This allows the airflow to settle and adhere more fully to areas closer to the air outlet, such as the back of the seat and the inner wall of the toilet bowl. This prevents these areas from being missed due to excessively strong airflow, thus avoiding ineffective sterilization. Furthermore, the low-speed airflow prolongs the suspension time of the sterilizing substance in the enclosed space, allowing it to fully contact the inner wall of the toilet bowl and the back of the seat, improving sterilization efficiency.

[0073] 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.

[0074] 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.

[0075] 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.

[0076] 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.

[0077] 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.

[0078] 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.

[0079] This embodiment provides a toilet seat assembly that can simultaneously sterilize and disinfect the inner wall and seat of the toilet, and can increase the amount and uniformity of mist on the toilet seat, thereby improving the sterilization effect.

[0080] like Figure 1 , Figure 2 as well as Figure 3 As shown, the toilet seat assembly 100 includes a seat ring 1, a seat plate 2, and an air outlet 3. The seat plate 2 is movably disposed above the seat ring 1; the air outlet 3 is provided with an air inlet 31 and at least one air outlet 32. The air inlet 31 is configured to connect to the toilet's sterilization device 300 for introducing sterilization airflow output from the sterilization device 300. The air outlet 32 ​​is located between the seat plate 2 and the seat ring 1. Specifically, the air outlet 32 ​​is located at the rear end of the seat plate 2 and can output airflow towards the front end area of ​​the seat ring 1. When the toilet's sterilization function is activated, the seat plate 2 is in the closed state. At this time, there is a gap between the seat plate 2 and the seat ring 1 that communicates with the air outlet 32, allowing the airflow output from the air outlet 32 ​​to enter the gap between the seat plate 2 and the seat ring 1. See also... Figure 3 The cover plate 2 is provided with an outer flange 21 along its outer periphery. The gap between the front end of the outer flange 21 and the seat ring 1 is greater than the gap between the rear end of the outer flange 21 and the seat ring 1.

[0081] It should be noted that, as Figure 1 and Figure 3 As shown, the front and back ends mentioned above are referenced to the front and back directions of the toilet.

[0082] The toilet seat assembly 100 provided in this embodiment provides a sterilizing airflow from the toilet sterilization device 300, which is output through the air outlet 32 ​​of the air outlet 3. By positioning the air outlet 32 ​​between the seat 2 and the seat ring 1, the sterilizing airflow can be output between the seat 2 and the seat ring 1. Part of the sterilizing airflow falls onto the inner wall of the toilet body 200 under gravity, sterilizing the inner wall of the toilet, while another part falls onto the seat ring 1, sterilizing it. Because the gap between the outer edge 21 of the seat 2 and the seat ring 1 is larger than the gap between the rear end of the outer edge 21 of the seat 2 and the seat ring 1, a gradually narrowing drainage channel, wider at the front and narrower at the back, can be formed between the seat ring 1 and the outer edge 21. When the sterilizing airflow (such as the sterilizing mist generated by atomization) enters the narrowing flow channel (wider at the front and narrower at the back) from the air outlet 32, according to the principle of fluid mechanics, the airflow will naturally converge and accelerate towards the area with less flow resistance and more space. Therefore, the change in the gap can actively guide the sterilizing airflow to the front area of ​​the seat ring 1 with a larger gap, so that more sterilizing airflow flows out from the front end. This ensures that even if the front end of the seat ring 1 is far away from the air outlet 32, it can still obtain sufficient and concentrated sterilizing airflow coverage, thereby significantly improving the sterilization effect of the most critical front area of ​​the seat ring 1, which is in the closest contact with the human body.

[0083] Compared with existing technologies that rely solely on fan speed and mist outlet angle, resulting in mist concentration in localized areas, the structure of the cover plate assembly 100 in this embodiment achieves automatic airflow distribution. The larger gap between the front end of the outer edge 21 of the cover plate 2 and the seat ring 1 ensures effective supply of sterilizing airflow to the front area of ​​the seat ring 1, allowing more sterilizing airflow to flow out from the front end. The smaller gap at the rear end of the outer edge 21 of the cover plate 2 prevents excessive loss of sterilizing airflow from this gap, enabling the sterilizing airflow to diffuse more evenly and adhere to the entire upper surface of the seat ring 1, eliminating sterilization dead zones, fundamentally overcoming the problem that only localized areas can guarantee sterilization effect, and effectively improving the sterilization effect.

[0084] In addition, the toilet seat assembly 100 can increase the amount and uniformity of mist on the seat ring 1 simply by placing the air outlet 32 ​​between the seat ring 2 and the seat ring 1, and by combining the gap changes between the seat ring 2 and the seat ring 1. It does not require a complicated structural design, which can reduce costs while ensuring the sterilization effect, and avoid the problems of high failure rate caused by complex structures.

[0085] For example, the sterilization device 300 includes an atomizing device that can generate a sterilizing mist after it is started.

[0086] like Figure 4 and Figure 5As shown, the gap between the outer flange 21 of the cover plate 2 and the seat ring 1 includes a first guide gap 41 and a second guide gap 42. The second guide gap 42 is located at the end of the first guide gap 41 away from the air outlet 32. The vertical dimension of the first guide gap 41 is consistent along the direction away from the air outlet 32; the vertical dimension of the second guide gap 42 gradually increases along the direction away from the first guide gap 41. The second guide gap 42 corresponds to the front end region of the seat ring 1.

[0087] Since the vertical dimension of the first guide gap 41 remains consistent along the front-to-back direction of the toilet, a stable airflow delivery zone can be formed. This ensures that the sterilizing airflow from the air outlet 32 ​​maintains a concentrated and stable flow state in the initial stage, effectively reducing airflow leakage at the first guide gap 41. This provides a foundation for the subsequent smooth and efficient delivery of airflow to the front area of ​​the seat ring 1. Because the vertical dimension of the second guide gap 42 gradually increases from back to front, after the airflow passes through the stable first guide gap 41, it can be guided and diffused towards the second guide gap 42, increasing the sterilizing airflow at the second guide gap 42. This improves the uniformity and coverage density of the mist in the front area of ​​the seat ring 1, optimizing the sterilization effect on the front area of ​​the seat ring 1.

[0088] Continue reading Figure 4 and Figure 5 The maximum dimension of the first guide gap 41 along the front-to-back direction of the toilet is L1, and the maximum dimension of the second guide gap 42 along the front-to-back direction of the toilet is L2. The value of L2 / (L1+L2) ranges from 0.15 to 0.35. (L1+L2) represents the total length of the gap between the lid 2 and the seat ring 1 along the front-to-back direction. Limiting the ratio of L2 to (L1+L2) to within the range of 0.15 to 0.35 ensures that the dimension of the second guide gap 42 is neither too short nor too long, guaranteeing that a sufficient amount of disinfectant can adhere to the front end of the seat ring 1. If the dimension of the second guide gap 42 is too short, the airflow will not diffuse sufficiently in the front end of the seat ring 1, resulting in less mist and a poorer disinfection effect. If the dimension of the second guide gap 42 is too long, the disinfectant airflow may overflow to the outside before reaching the very front end of the seat ring 1, also failing to guarantee a disinfection effect.

[0089] For example, the value of L2 / (L1+L2) can be 0.15, 0.2, 0.22, 0.25, 0.3, 0.32, etc., or it can be a value before the above adjacent values. There is no specific limitation here.

[0090] like Figure 5As shown, the vertical dimension of the first guide gap 41 is H1, the minimum vertical dimension of the second guide gap 42 is H2, and the maximum vertical dimension of the second guide gap 42 is H3. H2 is greater than or equal to H1, and H3 is greater than H2, ensuring that the second guide gap 42 forms a wider diffusion zone to guide airflow to the front end of the seat ring 1. Preferably, H2 is equal to H1, thus ensuring a smooth transition between the first guide gap 41 and the second guide gap 42, without any steps or other structures, avoiding obstruction of airflow.

[0091] For example, the value of H1 ranges from 0.4mm to 0.8mm; the value of H2 ranges from 0.4mm to 0.8mm; and the value of H3 ranges from 3mm to 5mm. The limitation of the vertical dimensions of the first guide gap 41 and the second guide gap 42 can ensure that the sterilizing airflow can diffuse to the front end of the seat ring 1, improve the amount and uniformity of the mist at the front end of the seat ring 1, and prevent the sterilizing airflow from overflowing too much before reaching the front end of the seat ring 1.

[0092] For example, H1 is 0.5mm, H2 is 0.5mm, and H3 is 4mm. Of course, in other embodiments, the values ​​of H1, H2, and H3 are set according to design requirements, as long as the amount of mist falling at the front end of the seat ring 1 can meet the sterilization requirements.

[0093] like Figure 1 and Figure 6 As shown, multiple air outlets 32 are provided. These multiple air outlets 32 include a first air outlet 321 and a second air outlet 322 and a third air outlet 323 respectively located on either side of the first air outlet 321. The air inlet 31 is connected to the first air outlet 321, the second air outlet 322, and the third air outlet 323. Figure 7 As shown, the first air outlet 321 extends along the front-to-back direction of the toilet. The sterilizing airflow output through the first air outlet 321 flows towards the front of the toilet, and most of the sterilizing mist falls onto the inner wall of the toilet through the opening of the seat ring 1, achieving sterilization and disinfection of the inner wall of the toilet. Along the direction from the rear to the front of the toilet, the second air outlet 322 and the third air outlet 323 gradually extend away from the first air outlet 321, so that one of the second air outlet 322 and the third air outlet 323 outputs airflow to the left to sterilize the left area of ​​the seat ring 1, and the other outputs airflow to the right to sterilize the right area of ​​the seat ring 1. Finally, the sterilizing airflows from the left and right sides converge at the front area of ​​the seat ring 1 and overflow from the front, achieving full coverage of the seat ring 1 with sterilizing mist. With at least three air outlets, the seat ring 1 can be evenly misted on both sides and the inner wall of the toilet. Combined with the flow channel design that is wider at the front and narrower at the back between the outer edge 21 of the lid 2 and the seat ring 1, the entire seat ring 1 and the inner wall of the toilet can be evenly misted, thus improving the sterilization effect.

[0094] like Figure 1 and Figure 7 As shown, in this embodiment, the air outlet 32 ​​is provided with three outlets, namely the first air outlet 321, the second air outlet 322, and the third air outlet 323, as described above. The airflow follows... Figure 1 and Figure 7 The flow, directed by the hollow arrow, sterilizes the inner wall of the toilet and the toilet seat.

[0095] Of course, in other embodiments, more air outlets 32 can be provided, as long as these multiple air outlets 32 include the first air outlet 321, the second air outlet 322 and the third air outlet 323 mentioned above.

[0096] like Figure 7 As shown, the angle between the second air outlet 322 and the first air outlet 321 is α, and the value of α can be in the range of 30° to 45°; and / or, the angle between the third air outlet 323 and the first air outlet 321 is β, and the value of β can be in the range of 30° to 45°. Limiting the angle α to the range of 30° to 45° ensures that the airflow output from the second air outlet 322 can fall as much mist as possible on the left side of the seat ring 1, preventing the airflow from deviating too much from the left side of the seat ring 1, and fully utilizing the sterilizing airflow output from the second air outlet 322. Limiting the angle β to the range of 30° to 45° ensures that the airflow output from the third air outlet 323 can fall as much mist as possible on the right side of the seat ring 1, preventing the airflow from deviating too much from the right side of the seat ring 1, and fully utilizing the sterilizing airflow output from the third air outlet 323.

[0097] Furthermore, the first air outlet 321 is located at the center of the toilet seat assembly 100, allowing the sterilizing airflow to evenly mist the left and right inner walls of the toilet, avoiding any sterilization dead zones. The second air outlet 322 and the third air outlet 323 are arranged in a mirror image symmetrically relative to the first air outlet 321, allowing the sterilizing airflow to evenly mist the left and right areas of the seat ring 1, improving the uniformity of mist distribution.

[0098] For example, the angle α between the second air outlet 322 and the first air outlet 321 can be 30°, 32°, 36°, 38°, 40°, 42°, etc., or a value between adjacent values ​​mentioned above; no specific limitation is made here. The angle β between the third air outlet 323 and the first air outlet 321 can be 30°, 32°, 36°, 38°, 40°, 42°, etc., or a value between adjacent values ​​mentioned above; no specific limitation is made here.

[0099] like Figure 6 and Figure 8As shown, the air outlet 32 ​​faces upward relative to the horizontal plane. That is, the air outlet 32 ​​has a certain angle of elevation relative to the horizontal plane, so that the flow path of the air after it is ejected is roughly parabolic, causing the fogging area to spread to the far end, ensuring that the fog can be better settled in the front area of ​​the seat ring 1.

[0100] For example, the angle between the air outlet 32 ​​and the horizontal plane is γ, and the value of γ can be in the range of 3° to 5°. By limiting the angle γ between the air outlet 32 ​​and the horizontal plane to the range of 3° to 5°, it is ensured that the airflow can be ejected at a certain angle of elevation and move in a relatively ideal parabolic trajectory, thereby accurately reaching the front end area of ​​the seat ring 1 and ensuring the amount of mist falling at the front end of the seat ring 1.

[0101] In this embodiment, the first air outlet 321, the second air outlet 322, and the third air outlet 323 all form an angle γ with the horizontal plane.

[0102] For example, the angle γ between the air outlet 32 ​​and the horizontal plane can be 3°, 4°, 5°, etc., but is not limited to the listed values ​​and ranges.

[0103] like Figure 1 and Figure 9 As shown, the toilet seat assembly 100 also includes an installation structure 5. The seat ring 1, seat 2, and air outlet 3 are all connected to the installation structure 5, which has an air inlet channel 521. The air inlet 31 is connected to the sterilization device 300 through the air inlet channel 521. The installation structure 5 provides an installation base for the seat 2, seat ring 1, and air outlet 3, and can be connected to the toilet body 200 to achieve the installation of the seat assembly 100 on the toilet body 200. By setting the air inlet channel 521, a connection channel can be established between the sterilization device 300 and the air outlet 3, so that the sterilizing substance generated by the sterilization device 300 can be smoothly delivered to the air outlet 3.

[0104] Specifically, see Figure 2 , Figure 9 as well as Figure 11 The mounting structure 5 includes a top cover 51, a base 52, and an outer decorative panel 53. The top cover 51 is fastened to the base 52, forming a mounting chamber 50 between the top cover 51 and the base 52. The mounting chamber 50 is used to install toilet components, providing a sealed protection for these components. Figure 10The upper cover 51 includes a first plate segment 511, a second plate segment 512, and a third plate segment 513 that are bent and connected in sequence. The third plate segment 513 extends from the second plate segment 512 in a direction away from the first plate segment 511, that is, it extends forward. The first plate segment 511, the second plate segment 512, and the third plate segment 513 are roughly bent in a Z-shape. The air outlet 3 is provided on the upper cover 51, and the outer decorative panel 53 is provided on the first plate segment 511 and covers the air outlet 3 to prevent the air outlet 3 from being exposed, thus serving an aesthetic and decorative purpose. The first plate segment 511, the second plate segment 512, the third plate segment 513, and the seat ring 1 are arranged sequentially from the rear end to the front end of the toilet. The cover plate 2 is located on the front side of the outer trim panel 53 and there is an air guide gap 54 between it and the third plate segment 513. The air outlet 32 ​​is roughly flush with the plane where the second plate segment 512 is located. It blows the airflow between the cover plate 2 and the seat ring 1 through the air guide gap 54 to achieve sterilization and disinfection of the inner wall of the toilet and the seat ring 1.

[0105] In this embodiment, both the seat ring 1 and the cover plate 2 are rotatably connected to the third plate segment 513, enabling them to be flipped open. Furthermore, a fourth plate segment 514 is connected to the end of the third plate segment 513 away from the second plate segment 512, and the rear end of the seat ring 1 is located above the fourth plate segment 514.

[0106] like Figure 9 , Figure 10 as well as Figure 12 As shown, the upper cover 51 is provided with an installation port 515, which is opened on the first plate segment 511, the second plate segment 512, and the third plate segment 513. The air outlet 3 is installed at the installation port 515. Specifically, a supporting plate 516 protrudes from the inner wall of the installation port 515. The air outlet 3 includes an installation plate 33 and a boss 34 protruding from the installation plate 33. The installation plate 33 is embedded in the installation port 515 and placed on the supporting plate 516. The boss 34 engages with the opening formed by the supporting plate 516 to achieve a stable installation of the air outlet 3 on the upper cover 51. After the outer trim panel 53 is fastened to the upper cover 51 by buckles and / or screws, it can cover the air outlet 3, ensuring that the air outlet 3 is installed firmly and securely.

[0107] like Figure 9 and Figure 12 As shown, the air inlet channel 521 is located on the base 52, and part of the air inlet channel 521 is located inside the mounting chamber 50 to connect with the air inlet 31. A first insert 35 is provided at the air inlet 31 of the air outlet 3, and a second insert 5211 is provided at the upper end of the air inlet channel 521. The first insert 35 and the second insert 5211 are sealed together to ensure that airflow from the sterilization device 300 is introduced into the air outlet 3.

[0108] like Figure 12 and Figure 13As shown, this embodiment also provides a toilet, including a toilet body 200, a sterilization device 300, and a toilet seat assembly 100 as described above. Both the seat assembly 100 and the sterilization device 300 are located on the toilet body 200, and the air inlet 31 of the air outlet 3 of the seat assembly 100 is connected to the sterilization device 300. Specifically, the mounting structure 5 of the seat assembly 100 can be installed on the toilet body 200 via a combination of a pin and a hole. The toilet body 200 is provided with a water tank, and the sterilization device 300 can be located inside the water tank.

[0109] Since the toilet includes the aforementioned cover assembly 100, it can simultaneously sterilize and disinfect the inner wall of the toilet body 200 and the seat ring 1, and can increase the amount and uniformity of mist on the seat ring 1, thereby improving the sterilization effect.

[0110] like Figure 2 As shown, the toilet also includes a spray gun 6, a drying device 7, and a lid-flipping drive mechanism 8. The spray gun 6, drying device 7, and lid-flipping drive mechanism 8 are all located within the mounting chamber 50 defined by the upper cover 51 and the base 52. The spray gun 6 and drying device 7 can extend out of the mounting chamber 50 to clean and dry the buttocks. The lid-flipping drive mechanism 8 may include a rotary motor, or an electric push rod and linkage mechanism, for automatically flipping and opening / closing the lid 2.

[0111] This embodiment also provides a toilet sterilization control method, using the toilet described above for control. The toilet also includes an airflow drive component 400, through which the sterilizing substance generated by the sterilization device 300 is delivered to the air outlet 32. Exemplarily, the airflow drive component 400 can be a fan or blower, as long as it can provide power to deliver airflow.

[0112] The toilet sterilization control method provided in this embodiment includes the following steps:

[0113] S1. Control the sterilization device 300 to start;

[0114] S2. Control the airflow drive unit 400 to run at a first speed for a first preset time;

[0115] S3. Control the airflow drive unit 400 to run at the second speed for the second preset duration;

[0116] The first rotational speed mentioned above is greater than the second rotational speed.

[0117] This sterilization control method uses time-series control of the airflow drive component 400. In the initial sterilization stage, the airflow drive component 400 is controlled to operate at a higher initial speed. This utilizes the powerful kinetic energy generated by the high-speed airflow to rapidly and forcefully deliver the sterilizing substance to areas farther from the air outlet 32, such as the front of the seat ring 1. This effectively overcomes the problem of early settling of the mist due to its own weight, ensuring initial effective coverage of the entire sterilization area, especially key distant locations (including the front area of ​​the seat ring 1). In the later sterilization stage, the airflow drive component 400 is switched to a lower second speed. In this stage, the airflow energy is reduced, and the dispersion of the sterilizing substance is gentler and slower. This allows the airflow to settle and adhere more fully to areas closer to the air outlet 32, such as the rear of the seat ring 1 and the inner wall of the toilet bowl. This prevents these areas from being missed due to excessively strong airflow, thus avoiding ineffective sterilization. Furthermore, the low-speed airflow prolongs the suspension time of the sterilizing substance in the enclosed space, allowing it to fully contact the inner wall of the toilet bowl and the rear of the seat ring 1, improving sterilization efficiency.

[0118] For example, the range of the first rotational speed is 4500 rpm to 6000 rpm. For example, the value of the first rotational speed is 4500 rpm, 4800 rpm, 5000 rpm, 5500 rpm, 5600 rpm, 6000 rpm, etc., but it is not limited to the listed values ​​and ranges. This embodiment does not impose strict limitations on this.

[0119] For example, the range of the second rotational speed is 3000 rpm to 4000 rpm. For example, the value of the second rotational speed is 3000 rpm, 3200 rpm, 3500 rpm, 3600 rpm, 3800 rpm, 4000 rpm, etc., but it is not limited to the listed values ​​and ranges. This embodiment does not impose strict limitations on this.

[0120] For example, the value range of the first preset duration is 5 min to 15 min. For example, the value of the first preset duration is 5 min, 6 min, 7 min, 8 min, 9 min, 10 min, 12 min, 13 min, 15 min, etc., but it is not limited to the listed values ​​and ranges. This embodiment does not impose strict limitations on this.

[0121] For example, the value range of the second preset duration is 2 min to 5 min. For example, the value of the second preset duration is 2 min, 2.5 min, 3 min, 3.5 min, 4 min, 4.5 min, 5 min, etc., but it is not limited to the listed values ​​and ranges. This embodiment does not impose strict limitations on this.

[0122] This sterilization control method combines the three air outlets of the first air outlet 321, the second air outlet 322, and the third air outlet 323, as well as the drainage channel formed by the gap between the outer edge 21 of the cover plate 2 and the seat ring 1 (wider at the front and narrower at the back), which enables the sterilization mist to fall evenly on the inner wall of the toilet body 200 and the left, right, and front areas of the seat ring 1, achieving excellent sterilization effect.

[0123] Furthermore, the sterilization process is controlled in segments, avoiding the continuous use of high-speed airflow drive components 400 throughout the entire sterilization cycle, thereby reducing overall energy consumption. Simultaneously, due to the more rational distribution and less escape of the sterilizing substances, the amount of sterilizing substances used can be reduced or the total sterilization time shortened while achieving the same or even better sterilization effect, thus achieving a balance between energy saving and high efficiency.

[0124] Obviously, the above embodiments of the present invention are merely examples for clearly illustrating the present invention, and are not intended to limit the implementation of the present invention. Those skilled in the art will be able to make various obvious changes, readjustments, and substitutions without departing from the scope of protection of the present invention. It is neither necessary nor possible to exhaustively describe all embodiments here. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present invention should be included within the scope of protection of the claims of the present invention.
