Referring to fig. 1 to 3, a drying device for an intelligent toilet according to an embodiment of the present invention mainly includes a base 1, an outer sleeve 2, an inner sleeve 3, a driving motor 4, and a driving gear 5.

The base 1 is arranged inside a toilet body or a toilet cover of the intelligent toilet and can be used for providing mounting positions or mounting spaces for the outer sleeve 2, the inner sleeve 3, the driving motor 4 and the driving gear 5.

The outer sleeve 2 is slidably mounted on the base 1, and the outer sleeve 2 can slide back and forth relative to the base 1 to extend out of the base 1 or retract back into the base 1.

The front end of the outer sleeve 2 is provided with an air outlet 21. When the outer sleeve 2 stretches back and forth relative to the base 1, or the outer sleeve 2 stretches out of the base 1, warm air can be sprayed out from the air outlet 21 to be dried.

The inner sleeve 3 is coaxially and movably inserted into the outer sleeve 2, i.e. the outer sleeve 2 is coaxially sleeved outside the inner sleeve 3. When the inner sleeve 3 coaxially rotates relative to the outer sleeve 2 inside the outer sleeve 2, the inner sleeve 3 can drive the outer sleeve 2 to extend and retract back and forth relative to the base 1, so that the extension and retraction function of the drying device is realized.

The driving motor 4 is in transmission connection with the inner sleeve 3 and is used for driving the inner sleeve 3 to rotate around the axis of the inner sleeve 3, so that the inner sleeve 3 can rotate coaxially relative to the outer sleeve 2 in the outer sleeve 2.

The driving gear 5 is arranged on an output shaft of the driving motor 4, and the driving gear 5 is in transmission connection with the inner sleeve 3. The drive gear 5 is used for power transmission between the drive motor 4 and the inner jacket tube 3, so that the drive motor 4 can control the inner jacket tube 3 to rotate about its axis.

Referring to fig. 3, in some examples, a mounting groove 11 is recessed downward on the top surface of the base 1, and the mounting groove 11 extends in the front-rear direction. The shape of the fitting groove 11 is adapted to the outer contour shape of the outer sleeve 2. As shown in fig. 3, the fitting groove 11 has an arc-shaped cross section. It will be appreciated that the fitting groove 11 may be semicircular in cross section, or other shapes.

The outer sleeve 2 is slidably mounted on the assembly groove 11 of the base 1 and can move back and forth along the assembly groove 11, so that the outer sleeve 2 can extend back and forth relative to the base 1.

Still referring to fig. 3, in some embodiments, two side edges of the inner wall of the assembling groove 11 are respectively provided with a guiding groove 12, the outer peripheral wall of the outer sleeve 2 is convexly provided with a sliding rib 22 corresponding to the guiding groove 12, and the sliding rib 22 is slidably connected in the guiding groove 12. The two guide grooves 12 are matched with the two sliding ribs 22, so that the outer sleeve 2 is limited on the base 1, and the outer sleeve 2 and the base 1 form stable sliding connection.

Still referring to fig. 3, the outer peripheral wall of the inner sleeve 3 is concavely provided with a rotary slideway 31, and the rotary slideway 31 spirally surrounds the outer peripheral wall of the inner sleeve 3. The inner wall of the outer sleeve 2 is convexly provided with a guide block 23, and the guide block 23 can extend into the rotating slideway 31. When the inner sleeve 3 rotates axially relative to the outer sleeve 2, the side wall of the rotating slideway 31 can extrude the guide block 23 and drive the guide block 23 to slide relatively along the rotating slideway 31, so as to drive the outer sleeve 2 to move back and forth relative to the inner sleeve 3. When the inner sleeve 3 is axially stationary relative to the base 1, the outer sleeve 2 can slide back and forth and stretch back and forth relative to the base 1.

In the present embodiment, the driving motor 4 is a forward/reverse rotation motor. When the driving motor 4 rotates forwards, the driving gear 5 drives the inner sleeve 3 to rotate forwards around the axis thereof, and further drives the outer sleeve 2 to extend forwards relative to the base 1. When the driving motor 4 rotates reversely, the driving gear 5 drives the inner sleeve 3 to rotate reversely around the axis thereof, and further can drive the outer sleeve 2 to extend and retract backwards relative to the base 1.

Still referring to fig. 3, in some embodiments, the rotational ramp 31 includes a threaded section 311, a front smooth section 312, and a rear smooth section 313 that extend integrally.

The threaded section 311 is helically wound around the outer peripheral wall of the inner sleeve 3. It will be appreciated that the pitch of the threaded section 311 and its length in the axial direction of the inner sleeve 3 can be adjusted according to the telescopic stroke of the outer sleeve 2.

A front smooth section 312 extends from the front end of the threaded section 311. A rear smooth section 313 extends at the rear end of the threaded section 311.

Smooth or round transitions are provided between the front smooth section 312 and the threaded section 311 and between the rear smooth section 313 and the threaded section 311, so that the guide block 23 can smoothly enter the front smooth section 312 and the rear smooth section 313 from the threaded section 311.

The helix angle of both the front and rear

smooth segments

312, 313 is greater than the helix angle of the threaded segment 311. It should be noted that the helix angle is the angle between the tangent to the threaded section 311, the front smooth section 312 or the rear smooth section 313 and the axis of the inner sleeve 3. Therefore, when the guide block 23 is relatively moved in the threaded section 311, its moving speed in the axial direction of the inner sleeve 3 is fast; and when the guide block 23 relatively moves in the front smooth section 312 or the rear smooth section 313, its moving speed in the axial direction of the inner tube 3 is slow. Therefore, when the outer sleeve 2 performs telescopic motion relative to the base 1, the telescopic speed of the outer sleeve 2 in the initial stage and the final stage is slower, so that the motion starting point and the motion end point of the outer sleeve 2 extending out of or retracting into the base 1 can be effectively buffered, and the telescopic range of the outer sleeve 2 can be more stable.

It will be appreciated that in some embodiments, the forward and aft

smooth segments

312, 313 may also be perpendicular to the axis of the inner sleeve 3 and extend circumferentially of the inner sleeve 3. At this time, when the guide block 23 moves relative to the front smooth section 312 or the rear smooth section 313, the outer tube 2 does not move in the axial direction of the inner tube 3, that is, the outer tube 2 does not extend or contract relative to the base 1.

Still referring to fig. 3, two rotary slideways 31 are provided and are arranged at equal intervals along the circumferential direction of the inner sleeve 3, i.e. in a central symmetrical structure. Correspondingly, two guide blocks 23 are arranged on the inner wall of the outer sleeve 2 in a centrosymmetric manner. It can be understood that the number of the rotating chutes 31 can be three, four or more, and a plurality of the rotating chutes 31 with central symmetry are matched with the guide blocks 23, so that the stress on each guide block 23 can be more balanced, and the relative rotation between the outer sleeve 2 and the inner sleeve 3 and the telescopic motion of the outer sleeve 2 can be smoother and more stable.

Referring to fig. 1 to 3, an outer ring gear 32 extending circumferentially is convexly arranged on the outer peripheral wall of the rear end portion of the inner sleeve 3. The centre line of the outer ring gear 32 is located on the axis of the inner sleeve 3. At this time, the drive gear 5 meshes with the outer ring gear 32, and both the center line of the drive gear 5 and the axis of the output shaft of the drive motor 4 are parallel to the axis of the inner tube 3. Therefore, when the driving motor 4 controls the driving gear 5 to rotate, the inner sleeve 3 can be driven to rotate axially.

It is understood that, instead of the driving gear 5, a structure such as a screw, a rack, etc. may be used to transmit power between the driving motor 4 and the inner sleeve 3, so as to control the axial rotation of the inner sleeve 3.

Referring to fig. 5 in conjunction with fig. 3, the inner tube 3 is a tubular structure, and both the front end and the rear end thereof are open. Air can enter the inner sleeve 3 through the rear end opening of the inner sleeve 3, enter the outer sleeve 2 through the front end opening of the inner sleeve 3, and finally be blown out through the air outlet 21 at the front end of the outer sleeve 2, so as to realize the drying function.

Referring to fig. 4 in conjunction with fig. 1-3, in some embodiments, the rear end of the outer sleeve 2 is provided with a rearwardly extending clamping arm 24. The clamping arms 24 are arranged in two numbers and are circumferentially and symmetrically distributed, and the two clamping arms 24 are arranged at intervals. The guide blocks 23 are arranged on the inner side walls of the clamping arms 24, and each clamping arm 24 can be provided with one or more guide blocks 23. It is understood that three, four or more clamping arms 24 can be provided, and a plurality of clamping arms 24 are arranged at equal intervals in the circumferential direction.

The clamping arm 24 of the outer sleeve 2 has certain elasticity, and the rear end part of the clamping arm 24 can be elastically expanded along the radial direction, so that the outer sleeve 2 is coaxially sleeved on the periphery of the inner sleeve 3, and the guide block 23 extends into the rotary slide way 31. Therefore, the design of the clamping arm 24 on the outer sleeve 2 can simplify the assembly difficulty between the outer sleeve 2 and the inner sleeve 3, improve the assembly speed between the outer sleeve 2 and the inner sleeve 3, further simplify the structure of the drying device and be beneficial to reducing the overall production cost of the intelligence.

Referring to fig. 4, in some embodiments, the inner side wall of the clamping arm 24 is recessed with a mounting slot 25. The guide block 23 is detachably mounted in the mounting groove 25, for example, by screwing, and the guide block 23 is protruded from the inner side wall of the clamping arm 24. The guide block 23 may be fixed in the mounting groove 25 by means of bonding. The guide block 23 may be made of metal so that the guide block 23 and the outer wall of the inner tube 3 can slide smoothly relative to each other.

It is understood that the guide block 23 may be integrally formed on the inner side wall of the clamping arm 24. The guide block 23 is formed on the inner side wall of the clamping arm 24 in a protruding manner, such as by injection molding or hot melting.

Referring to fig. 5 in conjunction with fig. 3, two guide blocks 23 are disposed on the inner sidewall of the outer sleeve 2 in a central symmetry manner, and respectively extend into and are disposed in a rotary slideway 31. When the inner sleeve 3 rotates coaxially relative to the outer sleeve 2, the two rotating slideways 31 can respectively extrude the two guide blocks 23, so that the guide blocks 23 are subjected to an external force in the axial direction, the outer sleeve 2 moves relative to the inner sleeve 3 along the axial direction, and the outer sleeve 2 stretches back and forth in the axial direction.

Fig. 6 is a schematic view of a state structure of a drying device according to another embodiment of the present invention. Fig. 7 is an exploded view of fig. 6. Fig. 8 is a schematic structural view of the outer sleeve 2 of fig. 7.

Referring to fig. 6 to 8, the drying apparatus of the present embodiment has the same basic structure as the drying apparatus of fig. 1 to 5, and the difference is only the structure of the rotary chute 31 on the outer peripheral wall of the inner casing 3.

Referring to fig. 7, in the present embodiment, the axial length of the rotary slide 31 on the outer peripheral wall of the inner sleeve 3 is longer, so the extension range of the outer sleeve 2 of the present embodiment is larger. That is, by adjusting the axial length of the rotary slide 31, the extension range and the extension length of the outer tube 2 with respect to the inner tube 3 and the base 1 can be appropriately adjusted.

Referring to fig. 7 and 8, in the present embodiment, the pitch of the rotary slide 31 is smaller, so that the moving speed of the outer sleeve 2 in the axial direction is slower when the guide block 23 slides relatively in the rotary slide 31. That is, by adjusting the pitch of the rotary slide 31, the moving speed of the outer tube 2 in the axial direction can be adjusted.
