Description

Technical Field

[0001] This utility model relates to the field of smart bathroom technology, and in particular to a drying device for a smart toilet seat, a smart toilet seat, and a smart toilet. Background Technology

[0002] With the improvement of living standards and the development of smart home technology, smart toilets are gradually gaining popularity among consumers due to their comfort, hygiene, and convenience. Traditional smart toilet seats are usually equipped with features such as heated seats, spray gun cleaning, and warm air drying to enhance the user's toilet experience.

[0003] However, traditional smart toilets often use fixed air outlets for their drying devices. The airflow direction is not adjustable, making it difficult to accurately cover the target area. This results in low drying efficiency, and the fixed air outlets are exposed to the elements for a long time, which can easily accumulate dust or water stains, affecting hygiene.

[0004] The above information disclosed in the background art of this application is only for understanding the background of the concept of this application, and does not indicate or imply that it includes information of the prior art. Utility Model Content

[0005] Therefore, it is necessary to provide a drying device for a smart toilet seat, a smart toilet seat, and a smart toilet to address the above-mentioned problems.

[0006] This application provides a drying device for a smart toilet seat, comprising:

[0007] A housing assembly, wherein the housing assembly is provided with an air duct and an air inlet and an air outlet connected to both ends of the air duct;

[0008] A fan, wherein the fan is installed within the air duct;

[0009] A drive unit is disposed on the housing assembly;

[0010] A gear assembly, which is connected to the drive member and is capable of rotating under the drive of the drive member;

[0011] A flow guide is inserted into the air outlet. The flow guide has a flow channel within it. A first end of the flow channel penetrates the flow guide to form a flow hole. A second end of the flow channel communicates with the air duct. The second end has a limiting protrusion. A rack is provided on the flow guide. The rack meshes with a gear assembly and can extend and retract along the axial direction of the air outlet to either an extended or retracted position under the drive of the gear assembly. In the retracted position, the flow guide retracts into the air outlet. During the extended movement, the flow guide extends at least partially beyond the air outlet, exposing the flow hole. The end face of the air outlet near the air duct abuts against the limiting protrusion to restrict the extension of the flow guide.

[0012] The aforementioned drying device for smart toilet seats can achieve at least the following beneficial effects: The drying device for smart toilet seats provided in this application achieves airflow delivery through an air duct and a connected fan within the housing assembly. A drive component rotates a gear assembly, which in turn controls the axial extension and retraction of the guide component along the air outlet via a rack and pinion meshing transmission. Furthermore, the meshing transmission structure of the gear assembly and rack and pinion improves the reliability and accuracy of the guide component's extension and retraction. In the extended position, the guide component partially extends beyond the air outlet, exposing the air outlet to direct the drying airflow. In the retracted position, the guide component completely retracts into the air outlet for concealment and protection. The limiting protrusion abuts against the end face of the air outlet, precisely limiting the extension stroke of the guide component.

[0013] In some embodiments, a limiting groove is formed on the wall of the air outlet, the limiting groove extends along the axial direction of the air outlet, and the outer surface of the guide member is provided with a sliding protrusion, the sliding protrusion being slidably inserted into the limiting groove. By setting an axially extending limiting groove on the wall of the air outlet and a matching sliding protrusion on the outer surface of the guide, the guide achieves precise guidance during its extension and retraction through the sliding engagement of the sliding protrusion and the limiting groove. This effectively prevents circumferential deflection or radial swaying of the guide during extension and retraction, ensuring that the rack and gear assembly always maintains a stable meshing state. At the same time, the engagement structure of the limiting groove and the sliding protrusion restricts the degree of freedom of movement of the guide, making it strictly move in a straight line along the axial direction of the air outlet. This avoids airflow leakage caused by the deflection of the guide and ensures the contact and limiting effect between the limiting protrusion and the end face of the air outlet, further improving the reliability and repeatability of the guide's extension and retraction. In addition, this guiding structure is simple and reliable, and stable operation of the guide can be achieved without the need for additional components.

[0014] In some embodiments, the sliding protrusion is adapted to the limiting groove.

[0015] In some embodiments, the sliding protrusion extends along the length of the guide member. By extending the sliding protrusion along the length of the guide member, the contact area between the sliding protrusion and the limiting groove is significantly increased, providing more stable guiding support for the guide member during its extension and retraction, and effectively dispersing the radial load on the guide member. This extended design ensures that the sliding protrusion maintains continuous contact with the limiting groove throughout the entire extension and retraction stroke of the guide member, avoiding the local stress concentration problem that may occur with traditional point protrusions, while also extending the wear life of the guide structure. The extended sliding protrusion also acts as a reinforcing rib, improving the structural rigidity of the guide member body and preventing vibration or deformation caused by airflow impact when the guide member is extended, further ensuring the stability of the air outlet direction of the guide hole. In addition, this continuous guiding structure makes the guide member move more smoothly and steadily during its movement, reducing the impact load when the gear assembly meshes with the rack and pinion, which helps to reduce the power loss and operating noise of the drive component.

[0016] In some embodiments, the number of limiting grooves is set to multiple, and the multiple limiting grooves are arranged at intervals along the circumference of the air outlet. The number of sliding protrusions is also set to multiple, and the multiple sliding protrusions are arranged at intervals along the circumference of the guide member. Each sliding protrusion corresponds to one of the limiting grooves. By setting multiple limiting grooves at intervals along the circumference of the air outlet and correspondingly setting multiple sliding protrusions along the circumference of the guide member, multiple sets of synchronously cooperating guide structures are formed, so that the guide member obtains all-round balanced guiding support during the extension and retraction movement, effectively suppressing any possible deflection or sway of the guide member.

[0017] In some embodiments, a through hole is formed in the wall of the air outlet. The gear assembly includes multiple gears rotatably connected to the housing assembly. The multiple gears mesh with each other for transmission. One gear is connected to the drive shaft of the drive member, and at least a portion of another gear passes through the through hole to mesh with the rack. By forming a through hole in the wall of the air outlet, one gear in the gear assembly can pass through the through hole and mesh with the rack of the guide member. At the same time, the meshing of multiple gears forms a multi-stage transmission structure, which not only effectively expands the torque transmission range of the drive member and makes the extension and retraction movement of the guide member smoother and more powerful, but also improves the transmission accuracy through multi-stage gear reduction, ensuring that the guide member can achieve precise position control.

[0018] In some embodiments, the second end of the flow guide has multiple flow guide holes, and the flow guide has multiple flow guide plates. A flow guide plate is positioned between any two adjacent flow guide holes, and the length direction of the flow guide plate is angled to the axial direction of the flow guide hole. The flow guide plate can guide the gas flowing out of the flow guide hole to a preset direction. By providing multiple flow guide holes at the second end of the flow guide and setting inclined flow guide plates between adjacent flow guide holes, precise directional control of the outlet airflow is achieved. This design allows the gas flowing out of the flow guide hole to be precisely guided to a preset direction by the flow guide plates, forming multiple directional airflow jets, significantly improving drying efficiency and avoiding energy waste caused by disordered airflow diffusion. Furthermore, the flow guide plates also act as reinforcing ribs, enhancing the structural rigidity of the flow guide end and preventing vibration noise under high-speed airflow impact.

[0019] In some embodiments, the drying device further includes a flow stabilizer cylinder disposed within the air duct. The flow stabilizer cylinder is located on the side of the fan near the guide member. Multiple flow stabilizers are arranged within the flow stabilizer cylinder, interconnected and extending radially outward along the axis of the flow stabilizer cylinder. By placing a flow stabilizer cylinder within the air duct on the side of the fan near the guide member, and arranging multiple interconnected flow stabilizers extending radially outward along the axis of the flow stabilizer cylinder, effective control and optimization of airflow are achieved. The structural arrangement of the flow stabilizer cylinder ensures that the airflow output from the fan first undergoes rectification by the flow stabilizers. The radially arranged flow stabilizers evenly divide and guide the airflow, eliminating turbulence and eddies, ensuring smooth airflow into the guide member. The radial extension of the flow stabilizers forms a multi-channel airflow distribution structure, maintaining the continuity of airflow and enhancing the overall structural strength through the connection between the flow stabilizers. This design ensures a stable airflow after passing through the flow stabilizer, providing uniform air intake conditions for precise airflow guidance of subsequent flow guides. Furthermore, the flow stabilizer's location near the fan outlet effectively suppresses airflow disturbances at their initial stage, preventing turbulence from being transmitted to downstream components. The radial flow stabilizer layout also optimizes the airflow path, reduces flow resistance, and ensures efficient energy transfer to the flow guides, ultimately achieving precise control of the drying airflow direction and velocity.

[0020] In some embodiments, the fan is a brushless DC centrifugal fan. The brushless DC centrifugal fan employs electronic commutation technology, eliminating the mechanical wear problems of traditional brushed motors and significantly improving the fan's service life and operational reliability. The centrifugal impeller structure generates high-pressure airflow, meeting the specific air pressure requirements of the drying process. Simultaneously, the brushless motor's speed can be precisely adjusted, allowing for more accurate airflow control. The fan's high efficiency reduces overall energy consumption, and its compact structure facilitates miniaturization of the drying device. The low noise characteristics of the brushless DC motor also improve the user experience, while its maintenance-free nature reduces maintenance costs during equipment use. This fan configuration, in conjunction with the flow stabilizer and guide vanes, further enhances the stability and directional controllability of the drying airflow.

[0021] In some embodiments, the housing assembly includes a first housing and a second housing, which are detachably connected and enclose each other to form the air duct. The first housing has the air outlet. By designing the housing assembly as a detachable first and second housing, the structural maintainability and assembly convenience of the drying device are optimized. The first and second housings are connected by detachable methods such as snap-fit ​​or threaded connection, together forming a complete airflow channel of the air duct. The air outlet on the first housing is directly connected to the drying area, ensuring that the airflow rectified by the flow stabilizer can be accurately guided to the air outlet through the guide. This split housing design facilitates the cleaning or maintenance of the internal components in the air duct.

[0022] This application also provides a smart toilet seat, which includes a core base and a drying device as described in any of the above embodiments, wherein the drying device is disposed on the core base.

[0023] This application also provides a smart toilet, which includes a toilet seat and a smart toilet lid as described in any of the above embodiments, wherein the smart toilet lid is disposed on the toilet seat.

[0024] The aforementioned smart toilet seat and smart toilet, because they include the drying device described in any of the above embodiments, also have at least the following beneficial effects: The drying device achieves airflow delivery through an air duct and a connected fan within the housing assembly. A drive component rotates a gear assembly, which in turn controls the axial extension and retraction of the guide component along the air outlet via a rack and pinion meshing transmission. The meshing transmission structure of the gear assembly and rack and pinion improves the reliability and accuracy of the guide component's extension and retraction. In the extended position, the guide component partially extends beyond the air outlet, exposing the air outlet to direct the drying airflow. In the retracted position, the guide component completely retracts into the air outlet for concealment and protection. The limiting protrusion abuts against the end face of the air outlet, precisely limiting the extension stroke of the guide component. Attached Figure Description

Many specific details are set forth in the following description to provide a full understanding of this utility model. However, this utility model can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this utility model. Therefore, this utility model is not limited to the specific embodiments disclosed below.

[0038] Please see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5In some embodiments, this application provides a drying device 13 for a smart toilet seat 12, which includes a housing assembly 100, a fan 200, a drive component 300, a gear assembly 400, and a guide component 500. The housing assembly 100 has an air duct 130 and an air inlet 140 and an air outlet 150 connected to both ends of the air duct 130. The fan 200 is disposed within the air duct 130. The drive component 300 is disposed within the housing assembly 100, and the gear assembly 400 is connected to the drive component 300 and can rotate under the drive of the drive component 300. The guide member 500 is inserted into the air outlet 150. A guide channel 510 is provided within the guide member 500. The first end of the guide channel 510 penetrates the guide member 500 to form a guide hole 530. The second end of the guide channel 510 communicates with the air duct 130 and is provided with a limiting protrusion 520. A rack 540 is provided on the guide member 500. The rack 540 meshes with the gear assembly 400 for transmission and can be driven by the gear assembly 400. Driven by 00, the air outlet 150 extends and retracts along its axial direction to either the extended or retracted position. In the retracted position, the guide member 500 retracts into the air outlet 150. During the extended movement, the guide member 500 extends at least partially outside the air outlet 150, and the guide hole 530 is exposed. The end face of the air outlet 150 near the air duct 130 abuts against the limiting protrusion 520 to restrict the extension of the guide member 500.

[0039] The aforementioned drying device 13 for the smart toilet seat 12 can achieve at least the following beneficial effects: The drying device 13 for the smart toilet seat 12 provided in this application realizes airflow delivery through the air duct 130 and the connected fan 200 provided in the housing assembly 100. The drive component 300 drives the gear assembly 400 to rotate, and then controls the guide component 500 to move axially along the air outlet 150 through the meshing transmission of the rack 540. Moreover, the meshing transmission structure of the gear assembly 400 and the rack 540 improves the reliability and accuracy of the extension and retraction movement of the guide component 500. In the extended position, the guide component 500 partially extends out of the air outlet 150, exposing the guide hole 530 to guide the drying airflow in a directional manner. In the retracted position, the guide component 500 is completely retracted into the air outlet 150 for concealment and protection. The limiting protrusion 520 abuts against the end face of the air outlet 150 to precisely limit the extension stroke of the guide component 500.

[0040] like Figure 5 , Figure 7 and Figure 8As shown, in some embodiments, a limiting groove 151 is formed on the wall of the air outlet 150, the limiting groove 151 extends along the axial direction of the air outlet 150, and a sliding protrusion 550 is provided on the outer surface of the guide member 500, the sliding protrusion 550 being slidably inserted into the limiting groove 151. By setting an axially extending limiting groove 151 on the wall of the air outlet 150 and a matching sliding protrusion 550 on the outer surface of the guide member 500, the guide member 500 achieves precise guidance during its extension and retraction through the sliding engagement of the sliding protrusion 550 and the limiting groove 151. This effectively prevents the guide member 500 from circumferentially deflecting or radially swaying during extension and retraction, ensuring that the rack 540 and the gear assembly 400 always maintain a stable meshing state. At the same time, the engagement structure of the limiting groove 151 and the sliding protrusion 550 restricts the degree of freedom of movement of the guide member 500, making it strictly move in a straight line along the axial direction of the air outlet 150. This avoids airflow leakage caused by the deflection of the guide member 500 and ensures the contact and limiting effect between the limiting protrusion 520 and the end face of the air outlet 150, further improving the reliability and repeatability of the extension and retraction of the guide member 500. In addition, this guiding structure is simple and reliable, and the stable operation of the guide member 500 can be achieved without the need for additional components.

[0041] In some embodiments, the sliding protrusion 550 is adapted to the limiting groove 151.

[0042] In some embodiments, the sliding protrusion 550 extends along the length of the guide member 500. By extending the sliding protrusion 550 along the length of the guide member 500, the contact area between the sliding protrusion 550 and the limiting groove 151 is significantly increased, providing more stable guiding support for the guide member 500 during its telescopic movement and effectively dispersing the radial load on the guide member 500. This extended design ensures that the sliding protrusion 550 maintains continuous contact with the limiting groove 151 throughout the entire telescopic stroke of the guide member 500, avoiding the local stress concentration problem that may occur with traditional point protrusions, and extending the durability of the guide structure. Wear life; the extended sliding protrusion 550 can also act as a reinforcing rib, improving the structural rigidity of the guide 500 body and preventing the guide 500 from vibrating or deforming due to airflow impact when extended, further ensuring the stability of the air outlet direction of the guide hole 530; in addition, this continuous guiding structure makes the guide 500 move more smoothly and steadily, reducing the impact load when the gear assembly 400 and rack 540 mesh, which helps to reduce the power loss and operating noise of the drive component 300.

[0043] In some embodiments, the number of limiting grooves 151 is set to multiple, and the multiple limiting grooves 151 are arranged at intervals along the circumference of the air outlet 150. The number of sliding protrusions 550 is set to multiple, and the multiple sliding protrusions 550 are arranged at intervals along the circumference of the guide member 500. The sliding protrusions 550 correspond one-to-one with the limiting grooves 151. By setting multiple limiting grooves 151 at intervals along the circumference of the air outlet 150 and correspondingly setting multiple sliding protrusions 550 around the circumference of the guide member 500, multiple sets of synchronously cooperating guide structures are formed, so that the guide member 500 obtains all-round balanced guiding support during the extension and retraction movement, effectively suppressing any possible deflection or sway of the guide member 500.

[0044] like Figure 3 and Figure 4 As shown, in some embodiments, a through hole 152 is provided on the wall of the air outlet 150. The gear assembly 400 includes a plurality of gears 410 rotatably connected to the housing assembly 100. The plurality of gears 410 mesh with each other for transmission. One gear 410 is connected to the drive shaft of the drive member 300, and at least a portion of another gear 410 passes through the through hole 152 to mesh with the rack 540 for transmission. By providing a through hole 152 on the wall of the air outlet 150, one of the gears 410 in the gear assembly 400 can pass through the through hole 152 to mesh with the rack 540 of the guide member 500. At the same time, the meshing of the plurality of gears 410 forms a multi-stage transmission structure, which not only effectively expands the torque transmission range of the drive member 300 and makes the extension and retraction movement of the guide member 500 more stable and powerful, but also improves the transmission accuracy through the multi-stage gear reduction, ensuring that the guide member 500 can achieve precise position control.

[0045] like Figure 2 and Figure 5As shown, in some embodiments, the second end of the flow guide 500 has a plurality of flow guide holes 530, and the flow guide 500 has a plurality of flow guide plates 560. A flow guide plate 560 is positioned between any two adjacent flow guide holes 530. The length direction of the flow guide plate 560 is angled to the axial direction of the flow guide hole 530. The flow guide plate 560 can guide the gas flowing out of the flow guide hole 530 to a preset direction. By providing a plurality of flow guide holes 530 at the second end of the flow guide 500 and providing flow guide plates 560 with an inclined angle between adjacent flow guide holes 530, precise directional control of the outlet airflow is achieved. This design allows the gas flowing out of the guide hole 530 to be precisely guided to a preset direction by the guide plate 560, forming multiple directional airflow jets, which significantly improves drying efficiency and avoids energy waste caused by disordered airflow diffusion. In addition, the guide plate 560 also acts as a reinforcing rib, enhancing the structural rigidity of the end of the guide component 500 and preventing vibration noise under the impact of high-speed airflow.

[0046] like Figure 6 As shown, in some embodiments, the drying device 13 further includes a flow stabilizer 600 disposed within the air duct 130. The flow stabilizer 600 is located on the side of the fan 200 near the guide member 500. The flow stabilizer 600 contains multiple flow stabilizers 610, which are interconnected and extend radially outward along the axis of the flow stabilizer 600. By providing a flow stabilizer 600 located on the side of the fan 200 near the guide member 500 within the air duct 130, and by providing multiple interconnected flow stabilizers 610 extending radially outward along the axis of the flow stabilizer 600, effective control and optimization of the airflow are achieved. The structural arrangement of the flow stabilizer 600 ensures that the airflow output from the fan 200 first passes through the rectifying effect of the flow stabilizers 610. The radially arranged flow stabilizers 610 evenly divide and guide the airflow, eliminating turbulence and eddies, and ensuring that the airflow smoothly enters the guide member 500. The radial extension of the flow stabilizer 610 forms a multi-channel airflow distribution structure, maintaining the continuity of airflow and enhancing the overall structural strength through the connection between the flow stabilizers 610. This design ensures that the airflow remains stable after passing through the flow stabilizer 600, providing uniform air intake conditions for the precise airflow guidance of the subsequent guide element 500. Simultaneously, the flow stabilizer 600's location near the fan 200 outlet effectively suppresses airflow disturbances at their initial stage, preventing turbulence from being transmitted to downstream components. The radial layout of the flow stabilizers 610 also optimizes the airflow path, reduces flow resistance, and ensures efficient energy transfer of the airflow to the guide element 500, ultimately achieving precise control of the drying airflow direction and velocity.

[0047] In some embodiments, the fan 200 is a brushless DC centrifugal fan 200. The brushless DC centrifugal fan 200 employs electronic commutation technology, eliminating the mechanical wear problems of traditional brushed motors and significantly improving the service life and operational reliability of the fan 200. The centrifugal impeller structure can generate high-pressure airflow, meeting the specific air pressure requirements of the drying process. Simultaneously, the speed of the brushless motor can be precisely adjusted, making airflow control more accurate. The high efficiency of this fan 200 reduces overall energy consumption, and its compact structure facilitates the miniaturization design of the drying device 13. The low noise characteristics of the brushless DC motor also improve the user experience, while the maintenance-free feature reduces maintenance costs during equipment use. This fan 200 configuration, in synergy with the flow stabilizer 600 and the guide vane 500, further enhances the stability and directional controllability of the drying airflow.

[0048] like Figure 6 As shown, in some embodiments, the housing assembly 100 includes a first housing 110 and a second housing 120, which are detachably connected and enclose the air duct 130. The first housing 110 is provided with the air outlet 150. By designing the housing assembly 100 as a detachable first housing 110 and second housing 120, the structural maintainability and assembly convenience of the drying device 13 are optimized. The first housing 110 and the second housing 120 are connected by detachable methods such as snap-fit ​​or threaded connection, together forming a complete airflow channel of the air duct 130. The air outlet 150 provided on the first housing 110 is directly connected to the drying area, ensuring that the airflow rectified by the flow stabilizer 600 can be accurately guided to the air outlet 150 by the guide 500. This split housing design facilitates the cleaning or maintenance of the internal components in the air duct 130.

[0049] like Figure 9 As shown, this application also provides a smart toilet seat 12, which includes a core base 14, a cover plate 15 rotatably connected to the core base 14, a seat ring 16 rotatably connected to the core base 14, and a drying device 13 as described in any of the above embodiments, wherein the drying device 13 is disposed on the core base 14.

[0050] like Figure 9 As shown, this application also provides a smart toilet 10, which includes a toilet seat 11 and a smart toilet lid 12 as described in any of the above embodiments, wherein the smart toilet lid 12 is disposed on the toilet seat 11.

[0051] The aforementioned smart toilet seat 12 and smart toilet 10, because they include the drying device 13 described in any of the above embodiments, also have at least the following beneficial effects: their drying device 13 achieves airflow delivery through the air duct 130 and the connected fan 200 provided in the housing assembly 100, uses the drive component 300 to drive the gear assembly 400 to rotate, and then controls the guide component 500 to move axially along the air outlet 150 through the meshing transmission of the rack 540. Moreover, the meshing transmission structure of the gear assembly 400 and the rack 540 improves the reliability and accuracy of the extension and retraction movement of the guide component 500. In the extended position, the guide component 500 partially extends out of the air outlet 150, exposing the guide hole 530 to guide the drying airflow in a directional manner. In the retracted position, the guide component 500 is completely retracted into the air outlet 150 for concealment and protection; the limiting protrusion 520 abuts against the end face of the air outlet 150 to precisely limit the extension stroke of the guide component 500.
