[0137] In the related art, the drying structure is generally driven to rotate by a driving mechanism to realize the drying function; however, since the driving mechanism is generally arranged at the side of the drying structure, at this time, the driving mechanism needs to be driven by a larger power to drive the drying structure to rotate, resulting in that the drying structure has a large energy consumption.

[0138] However, the drying device of the embodiment of the present application can greatly reduce the power required by the driving assembly 600 to drive the moisture absorption assembly 40 to rotate, thereby greatly reducing the energy consumption of the driving assembly 600; at the same time, since the first bottom wall 110 is concave at the rotation axis to form the containing recess 111 at the outside of the first bottom wall 110, and at least part of the fixing body 610 is located in the containing recess 111, the setting space of the driving assembly 600 in the rotation axis direction can be greatly reduced, thereby reducing the setting size of the drying device in the rotation axis direction, and realizing the thinning of the drying device in the axial direction.

[0139] In the embodiments of the present application, the structure of the shell assembly 10 is not limited. For example, as shown in FIG. 1, the shell assembly 10 can include a bottom shell 100 located at the side of the first space 340, a top shell 200 located at the side of the second space 350, and a heater shell 330 located at the side of the second space 350. The bottom shell 100 can include a first bottom wall 110. The bottom shell 100 and the top shell 200 can be fixedly connected by bolts, buckle structures, adhesive structures, etc. The bottom shell 100 and the heater shell 330 can be fixedly connected by bolts, buckle structures, adhesive structures, etc. The first space 340 includes a first humid cavity 341 and a second humid cavity 342. The second space 350 includes a dry cavity 351 and a heating cavity 352. The dry cavity 351 is defined by the top shell 200 and the moisture absorption assembly 40. The heating cavity 352 is defined by the heater shell 330 and the moisture absorption assembly 40. Here, the top shell 200, the bottom shell 100, and the heater shell 330 are different structural members. By separately providing the heater shell 330, the heater 840 can be conveniently installed and fixed. At the same time, when the heater is damaged, the heater 840 can be repaired by only disassembling the heater shell 330, which is convenient for repair. For another example, in other embodiments, the heater shell 330 and the top shell 200 can also be one structural member. At this time, the heater shell 330 and the top shell 200 can be integrally formed by injection molding. Here, the dry cavity 351 and the heating cavity 352 are defined by the top shell 200 and the moisture absorption assembly 40. Of course, in other embodiments, the top shell 200 and the bottom shell 100 can also be composed of at least two structural members.

[0140] In the embodiments of the present application, the structure of the drive assembly 600 is not limited. For example, the drive assembly 600 can include a motor. Here, the fixed body 610 can be a seat body of the motor, and the drive shaft 620 can be an output shaft of the motor. For another example, the drive shaft 620 can be eccentrically arranged relative to the fixed body 610. Here, the drive assembly 600 can include a motor and a speed reducer. The output shaft of the motor is fixedly connected or connected through a gear structure with the input shaft of the speed reducer, and the output shaft of the speed reducer forms the drive shaft 620. In this way, the speed of the motor can be adjusted through the speed reducer. At this time, the fixed body 610 includes the motor and the speed reducer except for the output shaft. It should be noted that when the drive shaft 620 is eccentrically arranged relative to the fixed body 610, the first mounting through hole 1131 can also be eccentrically arranged on the first bottom portion 113, so that the shape of the accommodating groove 111 is substantially the same as the shape of the fixed body 610.

[0141] In the embodiments of the present application, the structure of the moisture absorption assembly 40 is not limited, as long as it can absorb moisture in the air. For example, the moisture absorption assembly 40 can include a moisture absorption agent, which can be in a solid state or a liquid state. As an example, the moisture absorption agent can include solid silica gel and / or calcium chloride. For another example, the moisture absorption assembly 40 can include molecular sieve.

[0142] In some implementations of the embodiments of the present application, the drying device can further include a heat sink 700, the heat sink 700 is arranged on the circumferential side of the fixing body 610, at least part of the heat sink 700 is located in the accommodating groove 111, so as to dissipate heat for the driving assembly 600 through the heat sink 700, preventing the heat of the heater 840 from affecting the performance of the driving assembly 600.

[0143] In the present implementation, the structure of the heat sink 700 is not limited, as long as the heat sink 700 can dissipate heat for the driving assembly 600. For example, the heat sink 700 is connected with the first bottom 113, and the fixing body 610 is limited in the space defined by the heat sink 700 and the first bottom 113, so as to both dissipate heat for the driving assembly 600 through the heat sink 700 and keep the position of the driving assembly 600 relative to the shell assembly 10 unchanged through the heat sink 700, at this time, the driving assembly 600 does not need to be connected with the shell assembly 10 through other fixing structures, greatly reducing the structure of the drying device. For another example, the fixing body 610 can be fixedly connected with the first bottom 113 through a threaded structure, a buckle structure, etc.; the heat sink 700 can be arranged on the outer side of the fixing body 610 through a buckle structure, an adhesive structure, a threaded structure or a tight fit.

The first cylindrical portion 710 is annularly arranged on the circumferential side of the fixing body 610; the at least two fin portions 720 are arranged on the circumferential side of the first cylindrical portion 710 at intervals; the blocking portion 730 is connected with the first cylindrical portion 710; the blocking portion 730 is located on the side of the fixing body 610 away from the first bottom 113; the cable of the driving assembly 600 is led out from the heat sink 700 through the wire passing hole 740; the at least two mounting lug portions 750 are arranged on the circumferential side of the first cylindrical portion 710 at intervals; the mounting lug portion 750 is provided with a first through hole 751; the first bottom 113 is provided with a first connecting hole 167 corresponding in position to the first through hole 751, as shown in FIG. 13, so as to connect the first fastener 973 (as shown in FIG. 10) through the first through hole 751 and the first connecting hole 167.

[0145] In the present example one, the heat sink 700 is limited in the space defined by the first cylindrical portion 710 and the blocking portion 730.

[0146] In the present example one, the at least two fin portions 720 can increase the heat dissipation area of the heat sink 700, thereby improving the heat dissipation capacity of the heat sink 700.

[0147] In the first example, the position of the wiring through hole 740 is not limited. For example, as shown in FIG. 2, the wiring through hole 740 can be arranged at the connection between the sealing portion 730 and the first cylindrical portion 710. Of course, the wiring through hole 740 can also be arranged only in the sealing portion 730.

[0148] In the first example, the first connecting hole 167 can be a threaded hole, and the first fastener 973 can be a screw. Of course, in other examples, the heat sink 700 can also be connected to the first bottom wall 110 through a buckle structure, an adhesive structure, etc.

[0149] In the first example, the first cylindrical portion 710, the at least two fin portions 720, the sealing portion 730, and the at least two mounting lug portions 750 can be different parts of one structural member, and at this time, the first cylindrical portion 710, the at least two fin portions 720, the sealing portion 730, and the at least two mounting lug portions 750 can be integrally formed by injection molding. Alternatively, the first cylindrical portion 710, the at least two fin portions 720, the sealing portion 730, and the at least two mounting lug portions 750 can also be different structural members, and at this time, the different structural members can be fixedly connected through adhesion, welding, a threaded structure, etc.

[0150] Of course, in other examples, the heat sink 700 can also only include the first cylindrical portion 710 and the at least two fin portions 720. Alternatively, the heat sink 700 can also only include the first cylindrical portion 710, the at least two fin portions 720, and the sealing portion 730. Alternatively, the heat sink 700 can also only include the first cylindrical portion 710, the at least two fin portions 720, the sealing portion 730, and the wiring through hole 740. Alternatively, the heat sink 700 can also only include the first cylindrical portion 710, the at least two fin portions 720, and the at least two mounting lug portions 750.

[0151] In the embodiments of the present application, the first bottom wall 110 of the housing assembly forms the accommodating groove 111, and at least part of the driving assembly is located in the accommodating groove 111, which can greatly reduce the setting space of the driving assembly 600 in the direction of the rotation axis, thereby reducing the setting size of the drying device in the direction of the rotation axis; by arranging the driving assembly in the accommodating groove 111 of the first bottom wall 110, the driving assembly is far enough from the heater, and a heat sink is arranged for the driving assembly, so that the heat generation of the driving assembly can be controlled within a safe range; in this way, it is possible to arrange the driving assembly in the rotation axis direction of the moisture absorption assembly.

[0152] In some implementations of the embodiments of the present application, the moisture absorption assembly 40 can include a moisture absorption body 500, the moisture absorption body 500 defines a mounting hole 510 arranged along the rotation axis, the first boss 112 can be provided with a fixing wall portion 114 in a cylindrical shape, the fixing wall portion 114 is arranged along the circumferential side of the first mounting through hole 1131 and at least partially located in the mounting hole 510, the fixing wall portion 114 defines a mounting groove, the drying device can further include a bearing 810 arranged in the mounting groove, the outer ring 812 of the bearing 810 is fixed to the fixing wall portion 114, and the inner ring 811 of the bearing 810 is connected with the driving shaft 620, so as to support the driving shaft 620 through the bearing 810 and prevent the driving shaft 620 from shaking. At the same time, since at least part of the fixing wall portion 114 is located in the mounting hole 510 of the moisture absorption body 500, at least part of the bearing 810 is located in the mounting hole 510 of the moisture absorption body 500, so that the axial arrangement space of the bearing 810 can be greatly reduced, and the thickness of the drying device in the axial direction can be reduced.

[0153] Of course, in other implementations, the drying device can not include the bearing 810, and in this case, the first boss 112 can not be provided with the fixing wall portion 114 in a cylindrical shape.

[0154] In the present implementation, the outer ring 812 of the bearing 810 can be fixed to the fixing wall portion 114 by means of a tight fit or adhesion.

[0155] In the present implementation, the structure of the moisture absorption body 500 is not limited, as long as it can absorb moisture in the air. For example, the moisture absorption body 500 can include a moisture absorption agent. For another example, the moisture absorption body 500 can include a molecular sieve. The shape of the moisture absorption body 500 is not limited. For example, as shown in FIGS. 3 and 4, the moisture absorption body 500 can be in a disc structure.

[0156] In the present implementation, the inner ring 811 of the bearing 810 can be directly connected with the driving shaft 620, or can be connected with the driving shaft 620 through other structures.

[0157] For example, as shown in FIGS. 3, 4 and 5, the moisture absorption assembly 40 can further include a support assembly 400 for supporting the moisture absorption body 500 and connected with the driving shaft 620 and the inner ring 811 of the bearing 810 respectively, so that the support assembly 400 can also be supported by the bearing 810, thereby enabling the support assembly 400 to more stably support the moisture absorption body 500.

[0158] In the present example, as shown in FIG. 3 and FIG. 6, the support assembly 400 can include a first support 410; the first support 410 includes a second cylindrical portion 411, the second cylindrical portion 411 is located in the mounting hole 510, and an inner surface of the second cylindrical portion 411 defines a drive shaft accommodating hole 4111 arranged along the rotation axis; the drive shaft 620 is inserted into the drive shaft accommodating hole 4111, and an outer surface of the second cylindrical portion 411 is in contact with an inner surface of the inner ring 811 of the bearing 810.

[0159] Here, the cross section of the drive shaft 620 and the drive shaft accommodating hole 4111 can be non-circular, so that the drive shaft 620 and the drive shaft accommodating hole 4111 are fixedly arranged in the rotation direction. Of course, the cross section of the drive shaft 620 and the drive shaft accommodating hole 4111 can also be circular, at which time the drive shaft 620 and the drive shaft accommodating hole 4111 can be fixedly connected by means of a tight fit or adhesion.

[0160] Here, the outer surface of the second cylindrical portion 411 and the inner surface of the inner ring 811 of the bearing 810 can be fixedly connected by means of a tight fit or adhesion.

[0161] When the drive shaft 620 rotates, the drive shaft 620 drives the second cylindrical portion 411 and the inner ring 811 of the bearing 810 to rotate together, the outer ring 812 of the bearing 810 is stationary, and the inner ring 811 of the bearing 810 and the outer ring 812 of the bearing 810 are rollingly engaged by means of the rolling elements, which can greatly reduce the power required for the drive shaft 620 to drive the moisture absorption assembly 40 to rotate.

[0162] In the present example, the first support 410 can further include a third cylindrical portion 412 and a flange 413; the third cylindrical portion 412 includes a cylindrical bottom 4122 and a cylindrical side wall 4121, and the flange 413 is connected to an end of the cylindrical side wall 4121 away from the cylindrical bottom 4122; the second cylindrical portion 411 is located in a cavity defined by the cylindrical side wall 4121 and is connected to the cylindrical bottom 4122; at least part of the fixed wall portion 114 and at least part of the bearing 810 are located in a space defined by the outer surface of the second cylindrical portion 411 and the inner surface of the cylindrical side wall 4121, so as to reduce the axial installation space of the bearing 810. At the same time, at least part of the cylindrical side wall 4121 of the third cylindrical portion 412 is located in the mounting hole 510 of the moisture absorption body 500, so as to greatly reduce the axial installation space of the third cylindrical portion 412 and the axial thickness of the drying device.

[0163] In the present example, as shown in FIG. 3, FIG. 6 and FIG. 8, the first support 410 can further include at least one inclined rib 414 extending from the inner surface of the cylinder sidewall 4121 to the outer surface of the second cylinder portion 411 and connected with the cylinder bottom 4122, the top end of the inner ring 811 of the bearing 810 being in contact with the inclined rib 414 to define the axial position of the inner ring 811 of the bearing 810; the at least one inclined rib 414 being spaced apart from the outer ring 812 of the bearing 810.

[0164] Here, the second cylinder portion 411, the third cylinder portion 412, the flange 413 and the inclined rib 414 can be different parts of one structural member, in which case the second cylinder portion 411, the third cylinder portion 412, the flange 413 and the inclined rib 414 can be integrally formed by injection molding. Alternatively, the second cylinder portion 411, the third cylinder portion 412, the flange 413 and the inclined rib 414 can be different structural members, in which case the different structural members can be fixedly connected by bonding, welding, threaded structure, etc.

[0165] In the present example, as shown in FIG. 3, FIG. 7 and FIG. 9, the support assembly 400 can further include a second support 420 including a third connecting portion 421 in the form of a plate; the third cylinder portion 412 being inserted into the mounting hole 510 and connected with the third connecting portion 421; the flange 413 and the third connecting portion 421 being pressed against opposite sides of the moisture absorption body 500 so that the moisture absorption body 500 can be supported by both the second support 420 and the first support 410 and the bearing 810 can be supported by both the second support 420 and the first support 410, thereby enabling the moisture absorption body 500 to rotate more stably. At the same time, the flange 413 and the third connecting portion 421 being pressed against opposite sides of the moisture absorption body 500 can not only ensure the position of the moisture absorption body 500 and the support assembly 400 but also eliminate the need for other mounting structures on the moisture absorption body 500, thereby ensuring the overall strength of the moisture absorption body 500.

[0166] Here, the third cylinder portion 412 and the third connecting portion 421 can be fixedly connected by threaded structure, snap structure, bonding structure, etc.

[0167] Here, the second support 420 can further include a fourth connecting portion 422 connected with the third connecting portion 421; the third cylinder portion 412 and the fourth connecting portion 422 being inserted into the mounting hole 510 from opposite directions and being snap-connected with each other so as to improve the connection strength of the second support 420 and the first support 410.

[0168] Here, the third cylindrical portion 412 and the fourth connecting portion 422 can be connected by a snap structure or a clasp structure. Here, the fourth connecting portion 422 can be in a cylindrical structure. Of course, as shown in FIG. 9, the fourth connecting portion 422 can include at least two walls, which are arranged along the circumferential direction of the rotation axis and have a certain elasticity, so as to facilitate the connection of the third cylindrical portion 412 and the fourth connecting portion 422.

[0169] Here, the third cylindrical portion 412 and the fourth connecting portion 422 can be coaxially arranged. Of course, the third cylindrical portion 412 and the fourth connecting portion 422 can also be arranged in a substantially coaxial manner.

[0170] Here, the third connecting portion 421 and the fourth connecting portion 422 can be different parts of one structural member, and in this case, the third connecting portion 421 and the fourth connecting portion 422 can be integrally formed by injection molding. Alternatively, the third connecting portion 421 and the fourth connecting portion 422 can also be different structural members, and in this case, the third connecting portion 421 and the fourth connecting portion 422 can be fixedly connected by adhesion, welding, threaded structure, etc.

The third support member 430 includes a lap portion 432 located in the circumferential direction of the second through mounting hole 431. The lap portion 432 contacts the surface of the flange 413 facing the first boss 112, and the surface of the lap portion 432 away from the first boss 112 contacts the moisture absorption body 500. In this way, the area of the support assembly 400 supporting the moisture absorption body 500 is increased by the third support member 430, so as to improve the stability of the rotation of the moisture absorption body 500. Meanwhile, the third support member 430 in a spoke shape can also reduce the weight of the third support member 430.

[0172] Here, as shown in FIGS. 3, 6 and 7, the surface of the lap portion 432 away from the first boss 112 has at least two first protrusions 4321. The at least two first protrusions 4321 contact the moisture absorption body 500, so as to improve the tightness of the contact between the lap portion 432 and the moisture absorption body 500, and enable the third support member 430 to stably drive the rotation of the moisture absorption body 500.

[0173] Here, as shown in FIG. 6, the surface of the third connecting portion 421 facing the moisture absorption assembly 40 has at least two second protrusions 4211. The at least two second protrusions 4211 contact the moisture absorption body 500, so as to improve the tightness of the contact between the third connecting portion 421 and the moisture absorption body 500, and enable the third connecting portion 421 to stably drive the rotation of the moisture absorption body 500.

[0174] Here, the drying device can include only one of the second protruding portion 4211 and the first protruding portion 4321.
