[0002] Smart toilets are an important piece of equipment in modern bathroom spaces. Their functions have expanded from basic cleaning and washing to include cleaning and hot air drying. The original smart toilet drying system was fixed and could not accurately deliver hot air to the parts of the body that needed drying. The hot air was delivered in a fixed direction, and the delivery process had a certain distance, which caused the air volume and heat to be lost during the delivery. In addition, because the smart toilet drying system could not be moved or extended, it could not accurately perform the drying function. Utility Model Content

[0003] This utility model proposes a mobile hot air drying device for use in smart toilets. The hot air component, drive component and retractable arc-shaped air duct component on the main body of the device cooperate with each other. The drive component can drive the air duct component to extend and retract, so that the hot air can be directionally transported along the extended air duct component, effectively avoiding the large loss of air volume and heat caused by the diffusion of hot air in traditional drying systems without extension function.

[0004] A mobile hot air drying device for use in a smart toilet, designed for this purpose, includes a main body, on which a hot air assembly, a drive assembly, and a retractable and movable air duct assembly are provided.

[0007] The air guide plate is inclinedly installed inside the moving part.

[0008] An arc-shaped guide rail and an arc-shaped guide groove are provided between the air guide cover and the moving part. The arc-shaped guide rail and the arc-shaped guide groove are slidably engaged so that the moving part can reciprocate by extending or retracting relative to the air guide cover along a set arc-shaped trajectory.

[0009] The air guide cover and the moving part are provided with a forward stop limit part and a backward stop limit part, so that the moving part is limited and movable within the air guide cover.

[0025] The technical solutions of the present utility model will be clearly and completely described below with reference to the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. In order to make the above-mentioned objects, features and advantages of the present application more apparent and understandable, many specific details are set forth in the following description in order to provide a full understanding of the present application. However, the present application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar improvements without departing from the spirit of the present application. Therefore, the present application is not limited to the specific embodiments disclosed below.

[0026] See Figures 1-10 A mobile hot air drying device for use in smart toilets includes a device body 1, on which a hot air assembly 2, a drive assembly 4 and a retractable and movable air duct assembly 3 are provided. The hot air output end of the hot air component 2 is connected to the air duct component 3; The air duct assembly 3 is arc-shaped; The output end of the drive component 4 is connected to the telescopic movable end of the air duct component 3 for driving the air duct component 3 to perform telescopic movement.

[0027] The hot air assembly 2, drive assembly 4 and telescopic arc-shaped air duct assembly 3 on the main body 1 cooperate with each other. The drive assembly 4 can drive the air duct assembly 3 to telescopically move, so that the hot air can be directionally transported along the extended air duct assembly 3, effectively avoiding the large loss of air volume and heat caused by the diffusion of hot air in the traditional drying system without telescopic function; the arc-shaped air duct assembly 3 allows the air to flow along the arc trajectory when it is blown out, further reducing wind resistance and reducing air volume loss.

[0028] The air duct assembly 3 includes an arc-shaped air guide shroud 301 and a movable component 302. The movable component 302 is telescopically movably disposed inside the air guide shroud 301, and the output end of the drive assembly 4 is connected to the movable component 302 in a transmission connection. The hot air assembly 2 and the drive assembly 4 are fixedly connected to the air guide shroud 301.

[0029] The arc-shaped air guide shroud 301 and the arc-shaped movable component 302 constitute the air duct assembly 3. The movable component 302 extends and retracts within the air guide shroud 301. The air guide shroud 301 provides a stable mounting base for the hot air assembly 2 and the drive assembly 4, ensuring a secure connection between all components. The extension and retraction of the movable component 302 allows the air duct output end to be closer to the target drying area. Combined with the arc-shaped structure to reduce wind resistance, it enables the hot air to be directionally transported along the extended and retracted air duct, avoiding diffusion loss during hot air transport as in traditional non-extension designs. At the same time, the air guide shroud 301 protects the movable component 302 and the internal hot air, preventing external interference, ensuring the stability of hot air transport, and improving the overall reliability and drying effect of the device.

[0030] The movable component 302 is provided with an air inlet 303 and an air outlet 304 that connect to the hot air output end of the hot air assembly 2; The movable component 302 is provided with a guide plate 305 at the position corresponding to the air outlet 304; an air guide angle is formed between the inner side of the movable component 302 and the guide plate 305 to guide the flow of gas.

[0031] The air inlet 303 of the movable component 302 ensures that the hot air output from the hot air assembly 2 can smoothly enter the movable component 302. The air outlet 304, as the terminal of hot air delivery, precisely connects to the part to be dried after the movable component 302 extends or retracts. The air guide plate 305 corresponding to the air outlet 304 forms an air guide angle with the inner side of the movable component 302. This air guide design can guide the hot air towards the anus of the human body.

[0032] The air guide plate 305 is inclinedly disposed within the movable member 302. Hot air can be gathered between the air guide plate 305 and the movable member 302, so that the hot air is output along the air guide angle.

[0033] An arc-shaped guide rail 306 and an arc-shaped guide groove 307 are provided between the air guide cover 301 and the moving part 302. The arc-shaped guide rail 306 and the arc-shaped guide groove 307 are slidably engaged so that the moving part 302 can reciprocate by extending or retracting relative to the air guide cover 301 along a set arc trajectory.

[0034] The arc-shaped guide rail 306 and arc-shaped guide groove 307 between the air guide cover 301 and the moving part 302 slide together to ensure that the moving part 302 extends and retracts smoothly along the set arc trajectory. The air guide cover 301 and the moving part 302 are provided with a stop limit part 308 and a back limit part 309, so that the moving part 302 is limited to be moved and extended within the air guide cover 301.

[0035] The stop limiting part 308 includes a first limiting buckle disposed inside the air guide cover 301 and a second limiting buckle disposed on the outside of the moving part 302. During installation, the moving part 302 is inserted into the air guide cover 301, and the second limiting buckle undergoes elastic deformation and passes over the first limiting buckle.

[0036] The anti-reverse limiting part 309 includes a first limiting baffle disposed inside the air guide shroud 301 and a second limiting baffle disposed on the outside of the moving member 302. A step is formed between the first limiting baffle and the inner bottom wall of the air guide shroud 301. When the moving member 302 retracts, the second limiting baffle is supported on the step and abuts against the first limiting baffle. The bottom of the moving member 302 is provided with a relief groove corresponding to the step.

[0037] The forward stop limit 308 and the backward stop limit 309 can precisely limit the extension and retraction stroke of the moving part 302, preventing the moving part 302 from extending too far and detaching from the air guide cover 301 or retracting too much and touching the heat-generating part 202.

[0038] The moving part 302 is provided with an arc-shaped rack 310. The driving component 4 includes a motor 401 and a gear transmission group 402. The motor shaft of the motor 401 is connected to the input end of the gear transmission group 402. The gears of the gear transmission group 402 mesh with the arc-shaped rack 310. The motor 401 drives the moving part 302 to move through the gear transmission group 402.

[0039] The arc-shaped rack 310 of the moving part 302 meshes with the gear transmission group 402 of the drive assembly 4. The motor 401 achieves smooth power transmission through the gear transmission group 402, driving the moving part 302 to extend and retract. The gear transmission has the characteristics of high transmission efficiency and precise positioning.

[0040] The air guide cover 301 is provided with a mounting cavity 311 for mounting the gear transmission assembly 402. A connecting plate 5 is provided on the mounting cavity 311. The connecting plate 5 covers the opening of the mounting cavity 311 so that the gear transmission assembly 402 is encapsulated in the mounting cavity 311 and the motor 401 is fixed on the connecting plate 5.

[0041] The mounting cavity 311 of the air guide shroud 301 provides dedicated mounting space for the gear transmission assembly 402, ensuring the transmission components are securely installed. Encapsulating the gear transmission assembly 402 within the mounting cavity 311 effectively prevents dust, moisture, and other impurities from entering, avoiding corrosion and jamming of the transmission components and protecting the gear transmission assembly 402 for normal operation. A sealing ring is provided between the connecting plate 5 and the mounting cavity 311 to further improve sealing performance. The connecting plate 5 is fixed to the mounting cavity 311 of the air guide shroud 301 with screws.

[0042] The gear transmission assembly 402 includes a first gear 403, a second gear 404, a third gear 405, and an annular rack 406. The motor shaft of the motor 401 is connected to the first gear 403. The annular rack 406 covers the first gear 403 and the second gear 404. The first gear 403 and the second gear 404 respectively mesh with the annular rack 406. The third gear 405 is coaxially connected to the second gear 404 and meshes with the arc-shaped rack 310.

[0043] The first gear 403, the second gear 404, and the third gear 405 of the gear transmission assembly 402 cooperate with the ring rack 406 to achieve multi-stage power transmission. This amplifies the driving force of the motor 401, ensuring the smooth extension and retraction of the moving part 302, and precisely controls the transmission speed, making the extension and retraction of the moving part 302 smoother. The multi-stage transmission structure reduces transmission errors and improves the positioning accuracy of the moving part 302. At the same time, the design of the ring rack 406 covering the first gear 403 and the second gear 404 makes the power transmission smoother, reduces transmission noise, and improves user comfort.

[0044] Motor 401 is the motor of an existing smart toilet washer.

[0045] The hot air assembly 2 includes a fan 201 and a heating element 202. The air inlet of the fan 201 is connected to the outside of the main body 1 of the device, and the air outlet of the fan 201 is connected to the air guide shroud 301. The heating element 202 is fixedly installed inside the air guide shroud 301. The fan 201 is fixedly installed on the bracket 6, and the bracket 6 is fixedly connected to the air guide shroud 301.

[0046] The bracket 6 and the air guide shroud 301 are fixedly connected by a buckle 601 or screws. The bracket 6 is provided with a buckle 601, the air guide shroud 301 is provided with a fastening hole, and the bracket 6 is provided with a cavity for installing the fan 201. The buckle 601 of the bracket 6 is inserted into the fastening hole of the air guide shroud 301, and the air outlet of the fan 201 is correspondingly set with the opening of the air guide shroud 301.

[0047] The air guide cover 301 is provided with a limiting rib 312 for limiting and abutting against the outside of the moving part 302. The limiting rib 312 is used to compensate for the fit gap between the moving part 302 and the inner side of the air guide cover 301, thereby compensating for the installation gap and preventing the moving part 302 from moving inside the air guide cover 301 during the movement process.

[0048] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model shall be included within the protection scope of the present utility model.
