[0032] The utility model provides a drying device and an intelligent toilet.

[0033] Reference Figure 1 to Figure 6 In an embodiment of the utility model, a drying device comprises:

[0034] The hot air mechanism 10 is provided with an exhaust port 11;

[0035] An air guide component 20, the air guide component 20 is connected to the hot air mechanism 10, the air guide component 20 includes an air guide cylinder 21 that can move relative to the hot air mechanism 10, and an air outlet 22 that is connected to the air outlet 11 is provided at one end of the air guide cylinder 21 away from the air outlet 11, and the air outlet direction of the air outlet 22 intersects with the axis of the air guide cylinder 21;

[0036] The driving mechanism 30 is drivingly connected to the air guide tube 21 so as to drive the air guide tube 21 to perform telescopic movement along the axis.

[0037] The utility model provides a drying device applied to a smart toilet, which includes a main body, a toilet bowl arranged on the main body, and a toilet seat rotatably connected to the main body and a drying device installed on the main body. The smart toilet also includes a cleaning device installed on the main body, and the cleaning device is used to spray water to the private parts of the user to clean the private parts of the user.

[0038] The drying device disclosed in the utility model includes a hot air mechanism 10 to provide hot air, and a driving mechanism 30 can drive the air guide tube 21 on the air guide assembly 20 to telescopically move along the axis. It can be understood that the external airflow flows into the air guide tube 21 through the exhaust port 11 of the hot air mechanism 10, and then is output from the air outlet 22. Because the air outlet 22 arranged on the air guide tube 21 intersects with the axis of the air guide tube 21 to a certain extent, the wind blown out from the air outlet 22 is affected by the design angle and blows relatively concentratedly to the four sides of the user, thereby effectively increasing the wind force blowing to the user's private parts, which helps to quickly dry the water droplets attached to the private parts. Further, the air guide tube 21 of the utility model can be telescopically moved, so that the distance between the air outlet 22 and the user's private parts can be shortened during drying, thereby reducing wind force attenuation, and making it easier to set the air outlet angle according to actual conditions to obtain the best air outlet angle. In this embodiment, the definitions of "front" and "rear" are as follows: when the drying device is applied to the smart toilet, the side facing the user is the front, and the side facing away from the user is the rear. Therefore, the front refers to the front of the guide air cylinder 21 in the extended state, and the back refers to the state of the guide air cylinder 21 in the extended state. It can be understood that the air guide cylinder 21 is hollow and has an air outlet channel inside, so that the external air flow flows from the exhaust port 11 through the air outlet channel in the air guide cylinder 21 to the air outlet 22, and then blows out from the air outlet 22. This solution can provide a more personalized drying experience through the telescopic movement of the air guide cylinder 21 and the flexible adjustment of the direction of the air outlet 22. The user can adjust the drying wind direction and intensity according to personal feelings, so that the drying process is more in line with the body's needs and improves comfort. The hot air mechanism 10 is combined with the air guide component 20 that can perform telescopic movement, that is, dynamic adjustment, to concentrate the hot air on the parts that need to be dried, reduce the time required for drying, and avoid skin discomfort caused by long-term blowing. Compared with the traditional drying method with fixed air outlets, this design can also utilize heat energy more effectively, reduce energy consumption, and meet the requirements of energy conservation and environmental protection.

[0039] Reference Figure 1 to Figure 6In the embodiment of the utility model, the air guide assembly 20 also includes an external air duct 23, the external air duct 23 is connected to the hot air mechanism 10, the air guide tube is telescopically arranged in the external air duct 23, and the external air duct 23 and the air guide tube 21 are matched through the transmission structure 40, so that the air guide tube 21 can be telescopic relative to the external air duct 23 and can rotate around its own axis.

[0040] The hot air enters the air guide tube 21, and the air guide tube 21 performs telescopic movement relative to the outer air duct 23 under the action of the transmission structure 40, so that the distance between the air outlet 22 and the part of the human body that needs to be dried is the shortest, and the hot air escapes upward from the air outlet 22 to dry the part of the human body that needs to be dried. After the work is completed, the air guide tube 21 retracts backward relative to the outer air duct 23 under the action of the transmission structure 40, so that the entire air guide tube 21 returns to the initial shortened state. Therefore, by arranging a telescopic air guide tube 21 that can rotate around its own axis inside the outer air duct 23, the flexibility of the drying device is greatly enhanced. This design not only allows the air guide tube 21 to adjust the distance of hot air delivery by extending and contracting in length, but also can change the air outlet direction by rotation, realize accurate wind direction control in three-dimensional space, so that the airflow coming out of the air outlet 22 is relatively concentrated and blown to the user's four sides, thereby effectively increasing the wind force blowing to the user's private parts. In addition, the rotation function of the air guide 21 allows the hot air to be more evenly distributed to the area that needs drying, avoiding the problem of local overheating or uneven drying that may be caused by a fixed air outlet, and improving the drying efficiency and comfort. The design of wrapping the air guide 21 with the external air duct 23 maintains the compactness of the drying device, which is conducive to installation in a space-constrained environment such as a smart toilet. At the same time, this integrated design is also conducive to overall aesthetics and cleaning and maintenance.

[0041] Reference Figure 1 to Figure 6 In the embodiment of the utility model, the transmission structure 40 includes a positioning column 41 and a track groove 42. One of the air guide tube 21 and the external air duct 23 is provided with the positioning column 41, and the other is provided with the track groove 42. The extension direction of the track groove 42 is set at an angle with the axial direction of the air guide tube 21, and the positioning column 41 is slidably set in the track groove 42.

[0042] The positioning column 41 is fixed to the inside or outside of one of the air guide tube 21 or the external air duct 23, while the track groove 42 is set on the other component, and the two cooperate with each other through a specific angle configuration. The positioning column 41 is designed to slide along a specific track in the track groove 42. This design not only supports the axial telescopic movement of the air guide tube, but also cleverly guides it to rotate along the angle set by the track groove. In addition, the angle design between the track groove 42 and the axis of the air guide tube 21 determines the range and direction of the rotation of the air guide tube. By adjusting the size of this angle, the rotation amplitude of the air guide tube 21 can be controlled, thereby realizing the wide adjustment of the drying area to meet the needs of different users and application scenarios. Therefore, this design not only realizes the linear sliding of the air guide tube 21 through the precise positioning and coordination of the positioning column 41 and the track groove 42, but also the air guide tube 21 can also perform rotational movement, which greatly improves the controllability and accuracy of the drying area, which is not available in traditional drying devices. Complex motion control is achieved through a simple positioning column-track groove mechanism. This design simplifies the mechanical structure and reduces manufacturing costs and assembly complexity. The structure is easy to disassemble and assemble. Once maintenance or cleaning is required, users or technicians can easily inspect and maintain the positioning column and track groove, which improves the maintenance efficiency of the equipment. In addition, the sliding fit between the track groove and the positioning column, coupled with a reasonable angle design, can reduce friction and stress concentration during movement, and improve the durability of the overall structure and the stability of operation.

[0043] Reference Figure 1 to Figure 6 In the embodiment of the utility model, the hot air mechanism 10 includes a fan 12 and a heater 13. The fan 12 is provided with an air intake port and an air outlet 11 which are interconnected. The heater 13 is provided between the air outlet 11 and the external air duct 23.

[0044] The core of the hot air mechanism 10 is composed of a fan 12 and a heater 13. The fan 12 is responsible for inhaling external air and accelerating the air flow through its internal structure to form a strong airflow. Subsequently, the airflow passes through the heater 13, which quickly heats the air to a preset temperature, ensuring the effective supply of hot air. The connection design between the air intake and the air outlet 11 ensures the continuity of air circulation and improves the efficiency of hot air generation. It is understandable that the heater 13 can use advanced temperature control technology, which can quickly adjust the heating power as needed to ensure the stable output of hot air temperature. This not only improves the drying efficiency, but also prevents overheating from damaging the material or causing discomfort to the user. The fan 12 can be designed to emphasize low noise and high efficiency, and can maintain a low noise level even at high speed to improve the user experience. At the same time, its powerful wind output ensures the rapid transmission of hot air and shortens the drying time. Furthermore, during the hot air generation process, safety protection mechanisms such as overheating protection and current overload protection can be designed to ensure the safety and reliability of the entire drying process.

[0045] Reference Figure 1 to Figure 6 In the embodiment of the utility model, the driving mechanism 30 includes a driving member 31 and a transmission assembly 32. The driving member 31 is drivingly connected to the transmission assembly 32, and the transmission assembly 32 is drivingly connected to the air guide tube 21. The driving member 31 is used to drive the transmission assembly 32 to move, thereby moving the air guide tube 21.

[0046] In this embodiment, the output shaft of the driving member 31 is directly connected to the transmission assembly 32, which means that it is responsible for starting the movement of the entire transmission chain. When the driving member 31 starts to rotate, the rotation of its output shaft is transmitted to the transmission assembly 32 through a direct mechanical connection, so that the transmission assembly 32 also starts to rotate. There is a transmission connection between the transmission assembly 32 and the air guide 21, which means that the movement of the transmission assembly 32 is converted into the linear movement and rotational movement of the air guide 21. It is understandable that this conversion may be achieved by means of a screw-nut mechanism, a gear rack mechanism, a belt and pulley system or a complex connecting rod mechanism. For example, if a screw-nut mechanism is used, the rotation of the transmission assembly 32 will push the nut connected to the air guide 21 to move along the axial direction of the screw, thereby realizing the extension and rotation of the air guide 21. The entire movement process is powered by the driving member 31, and through the mechanical transmission of the transmission assembly 32, the air guide 21 is finally moved as expected (such as extension and / or rotation), thereby achieving the purpose of controlling the hot air guidance and intensity. It is understandable that the drive member 31 can be a variety of types such as an electric motor, a hydraulic motor or a pneumatic motor, and the most suitable drive source can be selected according to the specific application environment (such as power supply conditions, space restrictions, noise control requirements, etc.). Electric motors are suitable for most scenarios, while hydraulic or pneumatic drives are more suitable for occasions that require large torque output or specific working environments. The transmission component 32 can be designed in different forms such as gears, chains, belts or worm gears to achieve high efficiency, low noise or specific transmission ratio requirements. For example, the use of precision gear sets can ensure the accuracy and reliability of transmission; synchronous belt drives can also be used to reduce maintenance costs and reduce noise. It is understandable that sensors and controllers can also be added in this embodiment to realize intelligent management of the drive mechanism 30. The sensor monitors the load, temperature and other states of the drive member, and the controller adjusts the output of the drive member based on the feedback to achieve functions such as speed control and overload protection, thereby improving the overall automation level and safety of the system.

[0047] Reference Figure 1 to Figure 6In the embodiment of the utility model, the transmission assembly 32 includes a first transmission member 321 and a second transmission member 322. The first transmission member 321 is connected to the output shaft of the driving member 31, and the second transmission member 322 is partially arranged around the outer periphery of the first transmission member 321 and is connected to the first transmission member 321. The second transmission member 322 is connected to the air guide tube 21. The driving member 31 drives the first transmission member 321 to rotate, and then the second transmission member 322 drives the air guide tube 21 to move.

[0048] First, after the driving member 31 (such as a motor) receives the start signal, its built-in output shaft starts to rotate, providing the original power source. The output shaft of the driving member 31 is connected to the first transmission member 321 of the transmission assembly 32 through a direct mechanical connection (such as a key connection, a spline connection, etc.), so when the output shaft of the driving member 31 rotates, the first transmission member 321 also rotates in the same direction. The second transmission member 322 is partially arranged around the outer periphery of the first transmission member 321 and is connected to the first transmission member 321. Here, the transmission connection method may involve gear meshing, chain and sprocket matching, or some specific toothed belt and pulley structures. When the first transmission member 321 rotates, the second transmission member 322 on its outer periphery will also rotate. It is worth noting that due to the special layout of the second transmission member 322 and the first transmission member 321, the rotation of the second transmission member 322 may also be accompanied by the movement along the axial direction of the first transmission member 321, and this movement may be achieved through a thread, a spiral mechanism or other forms of mechanical conversion. It is understandable that the second transmission member 322 is connected to the air guide tube 21 by a certain transmission method (such as threaded connection, gear rack, etc.). Therefore, when the second transmission member 322 moves axially while rotating, this movement will be transmitted to the air guide tube 21, causing the air guide tube 21 to telescopically move along its axis. At the same time, the rotation of the second transmission member 322 may also realize the rotation of the air guide tube 21 around its axis, thereby realizing flexible positioning and direction adjustment of the air guide tube 21 in the drying device. This design realizes a complex and precise transmission process from the driving member 31 to the air guide tube 21 through the coordinated action of the two transmission members, which can not only drive the air guide tube 21 to telescopically move along the axis, but also realize its rotation around the axis, greatly enhancing the flexibility and functionality of the drying device.

[0049] Reference Figure 1 to Figure 6 In the embodiment of the utility model, the first transmission member 321 is a transmission wheel, and the second transmission member 322 is a transmission belt. The transmission belt and the transmission wheel are frictionally transmitted, thereby driving the air guide tube 21 to move.

[0050] In this scheme, the first transmission member 321 is a transmission wheel mounted on the output shaft of the driving member 31. The second transmission member 322 is a transmission belt, which passes around the outer circumference of the transmission wheel and maintains appropriate tension with the transmission wheel to ensure sufficient friction between the two. When the driving member 31 is started and rotated, the transmission wheel rotates accordingly. The transmission belt rotates with the transmission wheel due to the friction between it and the transmission wheel. In this embodiment, a part of the transmission belt is directly connected to the air guide cylinder 21 (for example, through a pulley fixed to the outside of the air guide cylinder 21 or directly fixed on the air guide cylinder 21), and the movement of the transmission belt will drive the air guide cylinder 21 to move along the axial direction. Optionally, the transmission belt can be a steel belt or a belt with a certain flexibility. Compared with hard connection methods such as gears, the transmission belt is easier to install and maintain, easy to adjust the tension, adapt to different installation conditions, and provide higher design flexibility. The transmission belt is usually lower in cost, reducing the overall cost of the equipment, and performs well in light load and low speed applications. The vibration and noise generated by the drive belt during operation are small, which helps to improve the smoothness and quietness of the equipment operation, and is particularly suitable for household appliances or noise-sensitive environments. In addition, in the case of overload, the drive belt is more likely to slip rather than be damaged immediately, which plays a certain role in overload protection and prolongs the service life of the entire system.

[0051] Reference Figure 1 to Figure 6 In the embodiment of the utility model, the first transmission member 321 is a transmission gear, and the second transmission member 322 is a flexible rack. The flexible rack meshes with the transmission gear for transmission, thereby driving the air guide tube 21 to move.

[0052] In this scheme, the first transmission member 321 is a transmission gear, which is also installed on the output shaft of the driving member 31. The second transmission member 322 is a flexible rack, and the flexible rack is provided with a tooth structure matching the transmission gear. When the driving member 31 is running, the transmission gear starts to rotate. Since the teeth of the flexible rack and the transmission gear are meshed with each other, the rotation of the gear will drive the flexible rack to move linearly along its length. If one end of the flexible rack is connected to the air guide tube 21 or through a specific connection structure, the linear movement of the rack will be directly converted into the telescopic movement of the air guide tube 21 along its axis. The meshing transmission of the gear and the rack provides higher transmission accuracy and rigidity, ensures the precise control and stability of the movement of the air guide tube 21, and is suitable for occasions requiring precise position control and heavy load conditions. In addition, the flexible rack can be designed into a curved shape to adapt to complex spatial layouts, which is extremely important for the design of space-constrained equipment (such as the internal structure of a smart toilet) and can effectively utilize limited space. And by designing different tooth shapes and rack paths according to needs, complex motion trajectories can be controlled. For example, it is not limited to linear movement, but can also be designed as curved or rotational motion, which improves the versatility of the device.

[0053] Reference Figure 1 to Figure 6 In an embodiment of the utility model, the air guide assembly also includes an air outlet portion 24, which is located at an end of the air guide tube 21 away from the exhaust port 11. The air outlet portion 24 has an end wall opposite to the end face of the air guide tube 21, and a side surrounding wall extending from the periphery of the end wall toward the air guide tube 21, and the air outlet 22 is arranged on the side surrounding wall.

[0054] The air outlet 24 is provided with an air outlet 22 on one side of the air guide tube 21, near the peripheral wall thereof, and this design is intended to more accurately control the direction of the hot air flow. As the air guide tube 21 telescopes, the air outlet 24 remains fixed, while the position and direction of the air outlet 22 change accordingly. Since the air outlet 22 is arranged toward one side of the peripheral wall of the air guide tube 21, its air outlet direction forms a certain angle with the axis of the air guide tube 21, which enables the hot air to be blown out at a predetermined angle when the air is discharged, and more accurately aligns with the area that needs to be dried. Through such a design, not only the adjustment of the length of the air guide tube 21 is achieved, but also the relative position and air outlet angle of the air outlet 22 can be changed through its movement to adapt to different drying requirements and object shapes. In addition, the air guide tube 21 is also designed with a rotation function, so the direction of the air outlet 22 will be more flexible, and the airflow can be better blown to the private parts of the human body. It can be understood that, in this embodiment, the air guide assembly 20 further includes connecting parts 25 provided at both ends of the air guide cylinder 22, and the connecting parts 25 are connected to the second transmission member 322. The connecting parts 25 are directly connected to the second transmission member 322 (whether it is a transmission belt or a flexible rack), and play a role in transmitting the movement of the transmission mechanism 30 to the air guide cylinder 21.

[0055] Reference Figure 1 to Figure 6 In the embodiment of the utility model, one end of the air guide tube 21 having the air outlet 22 is inclined downward relative to the air outlet 11.

[0056] When designing the air guide tube 21, one end thereof connected to the air outlet 22 is set at a downward tilt angle. This angle is not statically fixed, but is combined with the retractable and rotatable functions of the air guide tube 21. When the air guide tube is extended and rotated with the support of the bracket 50, the direction of the air outlet 22 can be flexibly adjusted in three-dimensional space. It can be understood that the downward tilt design of the air outlet 22 allows the hot air to form a certain downward tilt angle when leaving the air guide tube. Such a design can better match the physiological structure of the human body, ensuring that the hot air acts more directly and comfortably on the area that needs to be dried, while reducing the possibility of hot air directly impacting sensitive parts, thereby improving the comfort and efficiency of drying.

[0057] Reference Figure 1 to Figure 6In an embodiment of the utility model, the drying device further comprises a bracket 50 , the driving mechanism 30 and the air guide assembly 20 are both disposed on the bracket 50 , and the driving mechanism 30 is located below the air guide assembly 20 .

[0058] The bracket 50 serves as a supporting structure, integrating the drive mechanism 30 and the air guide assembly 20 together, and through a specific layout arrangement, that is, the drive mechanism 30 is located below the air guide assembly 20, it may help stabilize the center of gravity, reduce vibration, and facilitate maintenance and inspection, because the drive part usually requires more attention and possible maintenance operations.

[0059] The utility model also provides a smart toilet, which includes the above-mentioned drying device, and the specific structure of the drying device refers to the above-mentioned embodiment. Since the drying device adopts all the technical solutions of all the above-mentioned embodiments, it at least has all the beneficial effects brought by the technical solutions of the above-mentioned embodiments, which will not be repeated here one by one.

[0060] The above description is only an exemplary embodiment of the present invention, and does not limit the patent scope of the present invention. All equivalent structural changes made by using the contents of the present invention specification and drawings under the technical concept of the present invention, or directly / indirectly applied in other related technical fields are included in the patent protection scope of the present invention.
