[0136] For the drying device of the embodiment of the present application, since the driving assembly 600 is disposed at the rotation axis, the power for driving the moisture absorption assembly 40 to rotate by the driving assembly 600 can be greatly reduced, thereby greatly reducing the energy consumption of the driving assembly 600; at the same time, since the first bottom wall 110 is concave inward at the rotation axis to form an accommodation groove 111 on the outer side of the first bottom wall 110, at least part of the fixed body 610 is located in the accommodation groove 111, and the installation space of the driving assembly 600 in the rotation axis direction can also be greatly reduced, thereby reducing the installation size of the drying device in the rotation axis direction and realizing the thinning of the drying device in the axial direction.

[0137] In the embodiment of the present application, the structure of the housing assembly 10 is not limited. For example, as Figure 1As shown in the figure, the housing assembly 10 may include: a bottom case 100 located on the side of the first space 340, a top case 200 located on the side of the second space 350, and a heater case 330 located on the side of the second space 350. The bottom case 100 may include a first bottom wall 110; the bottom case 100 and the top case 200 may be fixedly connected by bolts, snap structures, adhesive structures, etc., and the bottom case 100 and the heater case 330 may be fixedly connected by bolts, snap structures, adhesive structures, etc. Among them, the first space 340 includes a first humid cavity 341 and a second humid cavity 342; the second space 350 includes a drying cavity 351 and a heating cavity 352; the moisture absorption component 40 and the top case 200 define the drying cavity 351, and the moisture absorption component 40 and the heater case 330 define the heating cavity 352; here, the top case 200, the bottom case 100, and the heater case 330 are different structural members. By separately providing the heater case 330, it is convenient to install and fix the heater 840; at the same time, when the heater is damaged, only the heater case 330 needs to be disassembled, and then the heater 840 can be repaired, which is convenient for maintenance. For another example, in some other implementation examples, the heater case 330 and the top case 200 may also be a single structural member. At this time, the heater case 330 and the top case 200 may be integrally formed by injection molding; here, the moisture absorption component 40 and the top case 200 define the drying cavity 351 and the heating cavity 352. Of course, in other embodiments, the top case 200 and the bottom case 100 may also be composed of at least two structural members.

[0138] In the embodiments of the present application, the structure of the driving component 600 is not limited. For example, the driving component 600 may include a motor; here, the fixed body 610 may be the seat body of the motor, and the driving shaft 620 is the output shaft of the motor. For another example, the driving shaft 620 may be eccentrically arranged relative to the fixed body 610; here, the driving component 600 may include a motor and a reducer; the output shaft of the motor is fixedly connected or connected in cooperation through a gear structure with the input shaft of the reducer, and the output shaft of the reducer forms the driving shaft 620; so as to adjust the rotation speed of the motor through the reducer. At this time, the fixed body 610 includes the parts of the motor and the reducer except the output shaft. It should be noted that when the driving shaft 620 is eccentrically arranged relative to the fixed body 610, the first mounting through hole 1131 may also be eccentrically arranged on the first bottom 113, so that the shape of the accommodating groove 111 is substantially the same as the shape of the fixed body 610.

[0139] In the embodiments of the present application, the structure of the moisture absorption component 40 is not limited, as long as it can absorb the moisture in the air. For example, the moisture absorption component 40 may include a moisture absorbent, and the moisture absorbent may be in a solid state or a liquid state. As an example, the moisture absorbent may include solid silica gel and / or calcium chloride. For another example, the moisture absorption component 40 may include molecular sieves.

[0140] In some optional implementation manners of the embodiments of the present application, the drying device may further include: a radiator 700, which is disposed on the peripheral side of the fixing body 610, and at least a part of the radiator 700 is located in the accommodation groove 111, so as to dissipate heat from the driving component 600 through the radiator 700 and prevent the heat of the heater 840 from affecting the performance of the driving component 600.

[0141] In this implementation manner, the structure of the radiator 700 is not limited as long as the radiator 700 can dissipate heat from the driving component 600. For example, the radiator 700 is connected to the first bottom 113, and the fixing body 610 is limited in the space defined by the radiator 700 and the first bottom 113, so that heat can be dissipated from the driving component 600 through the radiator 700 and the position of the driving component 600 relative to the housing assembly 10 can be kept unchanged by the radiator 700. At this time, the driving component 600 does not need to be connected to the housing assembly 10 through other fixing structures, greatly simplifying the structure of the drying device. For another example, the fixing body 610 can be fixedly connected to the first bottom 113 through a threaded structure, a snap structure, etc.; the radiator 700 can be disposed on the outer side of the fixing body 610 through a snap structure, an adhesive structure, a threaded structure or a tight fit.

[0142] Example 1, as Figure 2 shown, the radiator 700 may include: a first cylindrical portion 710, at least two fin portions 720, a blocking portion 730, a wire passing through hole 740, and at least two mounting ears 750. The first cylindrical portion 710 is disposed around the peripheral side of the fixing body 610; at least two fin portions 720 are arranged at intervals on the peripheral side of the first cylindrical portion 710; the blocking portion 730 is connected to 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 component 600 passes through the wire passing through hole 740 and is led out of the radiator 700; at least two mounting ears 750 are arranged at intervals on the outer side of the first cylindrical portion 710; a first through hole 751 is formed in the mounting ear 750; a first connection hole 167 corresponding to the position of the first through hole 751 is formed in the first bottom 113, as Figure 13 shown, so that a first fastener 973 passes through the first through hole 751 and is connected to the first connection hole 167, as Figure 10 shown.

[0143] In this Example 1, the radiator 700 is limited in the space defined by the first cylindrical portion 710 and the blocking portion 730.

[0144] In this Example 1, at least two fin portions 720 can increase the heat dissipation area of the radiator 700, thereby improving the heat dissipation capacity of the radiator 700.

[0145] In this Example 1, the position of the wire passing through hole 740 is not limited. For example, asFigure 2 As shown, the wiring through-hole 740 can be formed at the connection between the blocking portion 730 and the first cylindrical portion 710. Of course, the wiring through-hole 740 can also be formed only in the blocking portion 730.

[0146] In the first example, the first connection hole 167 can be a threaded hole, and the first fastener 973 can be a screw. Of course, in other examples, the radiator 700 can also be connected to the first bottom wall 110 through a snap structure, an adhesive structure, etc.

[0147] In the first example, the first cylindrical portion 710, at least two fin portions 720, the blocking portion 730, and at least two mounting ear portions 750 can be different parts of a structural member; at this time, the first cylindrical portion 710, at least two fin portions 720, the blocking portion 730, and at least two mounting ear portions 750 can be integrally formed by injection molding. Alternatively, the first cylindrical portion 710, at least two fin portions 720, the blocking portion 730, and at least two mounting ear portions 750 can also be different structural members, and at this time, the different structural members can be fixedly connected by bonding, welding, a threaded structure, etc.

[0148] Of course, in other examples, the radiator 700 can also include only the first cylindrical portion 710 and at least two fin portions 720. Alternatively, the radiator 700 can also include only the first cylindrical portion 710, at least two fin portions 720, and the blocking portion 730. Alternatively, the radiator 700 can also include only the first cylindrical portion 710, at least two fin portions 720, the blocking portion 730, and the wiring through-hole 740. Alternatively, the radiator 700 can also include only the first cylindrical portion 710, at least two fin portions 720, and at least two mounting ear portions 750.

[0149] In the embodiment of the present application, a receiving groove 111 is formed in the first bottom wall 110 of the housing assembly, and at least a part of the driving assembly is located in the receiving groove 111, which can greatly reduce the installation space of the driving assembly 600 in the direction of the rotation axis, thereby reducing the installation size of the drying device in the direction of the rotation axis; by arranging the driving assembly in the receiving groove 111 of the first bottom wall 110, the driving assembly is sufficiently far from the heater, and a radiator is provided for the driving assembly, so that the heat generated by the driving assembly can be controlled within a safe range; thus, it becomes possible to arrange the driving assembly in the rotation axial direction of the moisture absorption assembly.

[0150] In some optional implementation manners of the embodiments of the present application, the moisture absorption component 40 may include a moisture absorption body 500; the moisture absorption body 500 defines a mounting hole 510 arranged along the rotation axis; a cylindrical fixed wall portion 114 may be provided on the first boss 112, the fixed 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 fixed wall portion 114 defines a mounting groove; the drying device may further include: a bearing 810, the bearing 810 is arranged in the mounting groove; the outer ring 812 of the bearing 810 is fixed to the fixed wall portion 114; the inner ring 811 of the bearing 810 is connected to the drive shaft 620; so as to support the drive shaft 620 through the bearing 810 and prevent the drive shaft 620 from shaking. At the same time, since at least part of the fixed 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, thereby greatly simplifying the axial installation space of the bearing 810 and reducing the axial thickness of the drying device.

[0151] Of course, in other implementation manners, the drying device may not include the bearing 810. At this time, a cylindrical fixed wall portion 114 may not be provided on the first boss 112.

[0152] In this implementation manner, the outer ring 812 of the bearing 810 may be fixed to the fixed wall portion 114 by means of interference fit or bonding.

[0153] In this implementation manner, 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 may include a moisture absorbent. For another example, the moisture absorption body 500 may include molecular sieves. The shape of the moisture absorption body 500 is not limited. For example, as Figure 3 and Figure 4 shown, the moisture absorption body 500 may be a disc-shaped structure.

[0154] In this implementation manner, the inner ring 811 of the bearing 810 may be directly connected to the drive shaft 620 or may be connected to the drive shaft 620 through other structures.

[0155] For example, as Figure 3 、 Figure 4 and Figure 5 shown, the moisture absorption component 40 may further include a support component 400, the support component 400 is used to support the moisture absorption body 500 and is respectively connected to the drive shaft 620 and the inner ring 811 of the bearing 810; so as to support the support component 400 through the bearing 810, so that the support component 400 can more stably support the moisture absorption body 500.

[0156] In this example, as Figure 3 and Figure 6As shown, the support component 400 may include a first support member 410; the first support member 410 includes a second cylindrical portion 411, the second cylindrical portion 411 is located within the mounting hole 510, and the inner surface of the second cylindrical portion 411 defines a drive shaft receiving hole 4111 disposed along the rotation axis; the drive shaft 620 is inserted into the drive shaft receiving hole 4111, and the outer surface of the second cylindrical portion 411 contacts the inner surface of the inner ring 811 of the bearing 810.

[0157] Here, the cross-sections of the drive shaft 620 and the drive shaft receiving hole 4111 may be non-circular, so that the drive shaft 620 and the drive shaft receiving hole 4111 are fixedly arranged in the rotational direction. Of course, the cross-sections of the drive shaft 620 and the drive shaft receiving hole 4111 may also be circular. In this case, the drive shaft 620 and the drive shaft receiving hole 4111 may be fixedly connected by a tight fit or bonding.

[0158] Here, the outer surface of the second cylindrical portion 411 and the inner surface of the inner ring 811 of the bearing 810 may be fixedly connected by a tight fit or bonding.

[0159] 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 does not move. The inner ring 811 of the bearing 810 and the outer ring 812 of the bearing 810 are in rolling fit through rolling elements, which can greatly reduce the power for the drive shaft 620 to drive the moisture absorption component 40 to rotate.

[0160] In this example, the first support member 410 may further include: a third cylindrical portion 412 and a flange 413; the third cylindrical portion 412 includes a bottom 4122 and a side wall 4121, and the flange 413 is connected to one end of the side wall 4121 away from the bottom 4122; the second cylindrical portion 411 is located within the cavity defined by the side wall 4121 and is connected to the bottom 4122; at least part of the fixed wall portion 114 and at least part of the bearing 810 are located within the space defined by the outer surface of the second cylindrical portion 411 and the inner surface of the side wall 4121, so as to reduce the axial installation space of the bearing 810. At the same time, at least part of the side wall 4121 of the third cylindrical portion 412 is located within the mounting hole 510 of the moisture absorption body 500, so that the axial installation space of the third cylindrical portion 412 can be greatly simplified, and the axial thickness of the drying device can be reduced.

[0161] In this example, as Figure 6 and Figure 8As shown, the first support member 410 may further include at least one inclined rib portion 414. The at least one inclined rib portion 414 extends from the inner surface of the cylinder side wall 4121 to the outer surface of the second cylindrical portion 411 and is connected to the cylinder bottom 4122. The top end of the inner ring 811 of the bearing 810 contacts the inclined rib portion 414 to define the axial position of the inner ring 811 of the bearing 810; the at least one inclined rib portion 414 is spaced apart from the outer ring 812 of the bearing 810.

[0162] Here, the second cylindrical portion 411, the third cylindrical portion 412, the flanging 413, and the inclined rib portion 414 may be different parts of a structural member; at this time, the second cylindrical portion 411, the third cylindrical portion 412, the flanging 413, and the inclined rib portion 414 may be integrally formed by injection molding. Alternatively, the second cylindrical portion 411, the third cylindrical portion 412, the flanging 413, and the inclined rib portion 414 may also be different structural members. At this time, the different structural members may be fixedly connected by bonding, welding, threaded structures, etc.

[0163] In this example, as Figure 7 and Figure 9 shown, the support assembly 400 may further include: a second support member 420, and the second support member 420 includes a third connecting portion 421 in the shape of a plate; the third cylindrical portion 412 is inserted into the mounting hole 510 and is connected to the third connecting portion 421; the flanging 413 and the third connecting portion 421 are pressed against opposite sides of the moisture absorption body 500, so that the moisture absorption body 500 can be supported by the second support member 420 and the first support member 410, and the bearing 810 can also support the moisture absorption body 500 through the second support member 420 and the first support member 410, thereby enabling the moisture absorption body 500 to rotate more smoothly. At the same time, the flanging 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 do not require other mounting structures to be provided on the moisture absorption body 500, thereby ensuring the overall strength of the moisture absorption body 500.

[0164] Here, the third cylindrical portion 412 and the third connecting portion 421 may be fixedly connected by a threaded structure, a snap structure, a bonding structure, etc.

[0165] Here, the second support member 420 may further include a fourth connecting portion 422 connected to the third connecting portion 421; the third cylindrical portion 412 and the fourth connecting portion 422 are inserted into the mounting hole 510 from opposite directions and are snap-connected to improve the connection strength between the second support member 420 and the first support member 410.

[0166] Here, the third cylindrical portion 412 and the fourth connecting portion 422 may be snap-connected by a snap structure or a hook structure. Here, the fourth connecting portion 422 may be a cylindrical structure. Of course, asFigure 9 As shown, the fourth connecting portion 422 may include at least two wall bodies which are circumferentially spaced along the rotation axis, so that the at least two wall bodies have a certain elasticity to facilitate the snap connection between the third cylindrical portion 412 and the fourth connecting portion 422.

[0167] Here, the third cylindrical portion 412 and the fourth connecting portion 422 may be coaxially arranged. Of course, the third cylindrical portion 412 and the fourth connecting portion 422 may also be substantially coaxially arranged.

[0168] Here, the third connecting portion 421 and the fourth connecting portion 422 may be different parts of a structural member; in this case, the third connecting portion 421 and the fourth connecting portion 422 may be integrally formed by injection molding. Alternatively, the third connecting portion 421 and the fourth connecting portion 422 may also be different structural members, and in this case, the third connecting portion 421 and the fourth connecting portion 422 may be fixedly connected by bonding, welding, threaded structures, etc.

[0169] In this example, as Figure 6 and Figure 7 shown, the support assembly 400 may further include: a third support member 430, the third support member 430 being in a radial shape; a through second mounting through hole 431 is provided in the middle of the third support member 430, and the third cylindrical portion 412 passes through the second mounting through hole 431 and is inserted into the mounting hole 510; the third support member 430 includes a lapping portion 432 located circumferentially of the second mounting through hole 431, the surface of the lapping portion 432 facing the first boss 112 contacts the flanging 413, and the surface of the lapping portion 432 facing away from the first boss 112 contacts the moisture absorption body 500, so as to increase the area of the support assembly 400 for supporting the moisture absorption body 500 through the third support member 430, thereby improving the smoothness of the rotation of the moisture absorption body 500. At the same time, the third support member 430 in a radial shape can also reduce the weight of the third support member 430.

[0170] Here, as Figure 6 and Figure 7 shown, the surface of the lapping portion 432 facing away from the first boss 112 has at least two first protruding portions 4321; the at least two first protruding portions 4321 contact the moisture absorption body 500, so as to improve the tightness of the contact between the lapping portion 432 and the moisture absorption body 500, and enable the third support member 430 to stably drive the moisture absorption body 500 to rotate.

[0171] Here, as Figure 6 shown, the surface of the third connecting portion 421 facing the moisture absorption assembly 40 has at least two second protruding portions 4211; the at least two second protruding portions 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 moisture absorption body 500 to rotate.

[0172] Here, the drying device may also include only one of the second convex portion 4211 and the first convex portion 4321.

[0173] Of course, in other examples, the support assembly 400 may also be of other forms of structures. For example, the support assembly 400 may only include the first support member 410. Here, the first support member 410 may include a second cylindrical portion 411, a third cylindrical portion 412, and a flanging 413. The first support member 410 may support the moisture absorption body 500 through the flanging 413. Here, the first support member 410 may also include the second cylindrical portion 411 and the third cylindrical portion 412. The third cylindrical portion 412 and the mounting hole 510 of the moisture absorption body 500 may be connected by a tight fit or bonding. The first support member 410 may support the moisture absorption body 500 through the third cylindrical portion 412. Also for example, the support assembly 400 may only include the first support member 410 and the second support member 420. Here, the first support member 410 may include a second cylindrical portion 411, a third cylindrical portion 412, and a flanging 413. The second support member 420 may include a third connecting portion 421. The support assembly 400 supports the moisture absorption body 500 through the flanging 413 and the third connecting portion 421. Here, the first support member 410 may include a second cylindrical portion 411, a third cylindrical portion 412, and a flanging 413. The second support member 420 may include a third connecting portion 421 and a fourth connecting portion 422. The support assembly 400 supports the moisture absorption body 500 through the flanging 413 and the third connecting portion 421. Again for example, the support assembly 400 may include the first support member 410, the second support member 420, and the third support member. Here, the first support member 410 may include a second cylindrical portion 411 and a third cylindrical portion 412. The second support member 420 may include a third connecting portion 421. The third support member may be fixedly connected to one end of the cylindrical side wall 4121 of the third cylindrical portion 412 away from the cylinder bottom 4122 by a threaded structure, snap connection, welding, etc. The support assembly 400 supports the moisture absorption body 500 through the third connecting portion 421 and the third support member. Here, the first support member 410 may include a second cylindrical portion 411 and a third cylindrical portion 412. The second support member 420 may include a third connecting portion 421 and a fourth connecting portion 422. The third support member may be fixedly connected to one end of the cylindrical side wall 4121 of the third cylindrical portion 412 away from the cylinder bottom 4122 by a threaded structure, snap connection, welding, etc. The support assembly 400 supports the moisture absorption body 500 through the third connecting portion 421 and the third support member.

[0174] In some optional implementation manners of the embodiments of the present application, such as Figure 10 and Figure 11As shown, the housing assembly 10 may include a bottom case 100 on the side of the first space 340 and a top case 200 on the side of the second space 350. The bottom case 100 may include a first bottom wall 110.

[0175] In this implementation, as Figure 10 and Figure 13 shown, the bottom case 100 may further include: a first side wall 170, a fixing wall portion 114, two first convex arms 115, and a first step portion 161. The first side wall 170 is located on the peripheral side of the first bottom wall 110; the fixing wall portion 114 is disposed on the first boss 112 and on the peripheral side of the first mounting through hole 1131; the two first convex arms 115 extend from the first boss 112 to the outer peripheral side to the first side wall 170; the two first convex arms 115 divide the first space 340 into a first humid cavity 341 and a second humid cavity 342 distributed circumferentially; the first step portion 161 is connected to the first bottom wall 110 and the first side wall 170 respectively; the first step portion 161 may be in a semi-arc shape and is disposed on one side of the first mounting through hole 1131; the first step portion 161 is located on the side of the first humid cavity 341.

[0176] Here, the shape of the fixing wall portion 114 is not limited. For example, the fixing wall portion 114 is in a cylindrical shape. The fixing wall portion 114 and the first mounting through hole 1131 may be coaxially arranged or substantially coaxially arranged. Of course, the fixing wall portion 114 may not be in a cylindrical shape.

[0177] Here, the first step portion 161 may be coaxially disposed on one side of the first mounting through hole 1131, or the first step portion 161 may also be substantially coaxially disposed on one side of the first mounting through hole 1131.

[0178] In this implementation, as Figure 11 and Figure 16As shown, the top shell 200 may include: a first top wall 210, a second side wall 250, and a second step portion 260. The first top wall 210 and the first bottom wall 110 are axially spaced apart; a part of the first top wall 210 is concave to form a fan-shaped heating groove 211 on the outer side of the first top wall 210 and a fan-shaped convex portion on the inner side of the first top wall 210; a fan-shaped heating through hole 2121 is provided on the second bottom 212 of the heating groove 211; the convex portion forms a second boss 213 at the rotation axis and two second convex arms 214 extending from the second boss 213 to the outer peripheral side on both sides of the heating through hole 2121; the second boss 213 and the first boss 112 are axially located on opposite sides of the moisture absorption component 40, and the two second convex arms 214 and the two first convex arms 115 are axially located on opposite sides of the moisture absorption component 40; the two second convex arms 214 divide the second space 350 into a circumferentially distributed drying cavity 351 and a heating cavity 352; the drying cavity 351 and the first humid cavity 341 are axially corresponding; the heating cavity 352 and the second humid cavity 342 are axially corresponding. By forming a fan-shaped heating groove 211 on the outer side of the first top wall 210, the installation space of the heater shell 330 in the axial direction of the rotation axis can be reduced.

[0179] It should be noted that here, the heating groove 211 may be generally fan-shaped, and the heating through hole 2121 may be generally fan-shaped.

[0180] Here, the second side wall 250 and the first side wall 170 may be fixedly connected by a threaded structure, a snap structure, an adhesive structure, etc.

[0181] Here, the second step portion 260 and the second boss 213 may be coaxially arranged, or the second step portion 260 and the second boss 213 may be generally coaxially arranged.

[0182] In this implementation, the bottom shell 100 may further include at least three third convex portions 162, and the at least three third convex portions 162 are respectively provided in areas of the first step portion 161 and the two first convex arms 115 close to the first side wall 170; the distance between the third convex portions 162 on the bottom shell 100 and the moisture absorption component 40 is the smallest axially; that is, the structure on the bottom shell 100 with the smallest axial distance from the moisture absorption component 40 is the third convex. The moisture absorption component 40 may be deformed during long-term use, and the moisture absorption component 40 may contact the bottom shell 100. At this time, the moisture absorption component 40 may contact the third convex. Since the contact area between the third convex and the moisture absorption component 40 is small, the friction force during the rotation of the moisture absorption component 40 can be reduced; the third convex can prevent the moisture absorption component 40 from contacting the bottom shell 100 in a large area due to deformation.

[0183] Here, the number of the third protrusions is not limited. As Figure 14 shown, the bottom case 100 may include four third protrusion parts 162. Two third protrusion parts 162 are correspondingly arranged in the regions of the two first convex arms 115 close to the first side wall 170, and the two third protrusion parts 162 are arranged at intervals on the first step part 161.

[0184] In this implementation manner, the top case 200 may further include at least four fourth protrusion parts 270. The at least four fourth protrusion parts 270 are respectively correspondingly arranged on the second step part 260, in the regions of the two second convex arms 214 close to the second side wall 250, and on the second boss 213. The distance between the fourth protrusion parts 270 on the top case 200 and the moisture absorption component 40 in the axial direction is the smallest. That is, the structure on the top case 200 with the smallest distance from the moisture absorption component 40 in the axial direction is the fourth protrusion. The moisture absorption component 40 may be deformed during long-term use, and the moisture absorption component 40 may contact the top case 200. At this time, since the distance between the fourth protrusion parts 270 on the top case 200 and the moisture absorption component 40 in the axial direction is the smallest, the moisture absorption component 40 may contact the fourth protrusion. Since the contact area between the fourth protrusion and the moisture absorption component 40 is small, the friction force during the rotation of the moisture absorption component 40 can be reduced. The fourth protrusion can prevent the moisture absorption component 40 from contacting the top case 200 in a large area due to deformation.

[0185] Here, the number of the fourth protrusions is not limited. As Figure 17 shown, the top case 200 may include six fourth protrusion parts 270. Two fourth protrusion parts 270 are correspondingly arranged in the regions of the two second convex arms 214 close to the second side wall 250, three fourth protrusion parts 270 are arranged at intervals on the second step part 260, and one fourth protrusion part 270 is arranged on the second boss 213.

[0186] In this implementation manner, the drying device may also include only one of the third protrusions and the fourth protrusions.

[0187] In this implementation manner, as Figure 13 and Figure 14As shown, the first side wall 170 has a first notch 171 and a second notch 172. The first notch 171 communicates with the first humid cavity 341 and is located closer to the second humid cavity 342 side. The second notch 172 communicates with the second humid cavity 342. The bottom shell 100 may further include: a second bottom wall 120, a third bottom wall 130, a fourth bottom wall 140, and a fifth bottom wall 150. The second bottom wall 120 is circumferentially disposed on one side of the first notch 171 and is connected to the first bottom wall 110 through a first inclined wall 164. The second bottom wall 120 is provided with an air inlet 166. The axial distance between the second bottom wall 120 and the top shell 200 is greater than the axial distance between the first bottom wall 110 and the top shell 200. The fourth bottom wall 140 is circumferentially disposed on one side of the second notch 172 and is connected to the first bottom wall 110 through a second inclined wall 165. The axial distance between the fourth bottom wall 140 and the top shell 200 is greater than the axial distance between the first bottom wall 110 and the top shell 200. A drain port 141 is opened at the low point of the fourth bottom wall 140. The fifth bottom wall 150 is disposed between the second bottom wall 120 and the fourth bottom wall 140 and is connected to the fourth bottom wall 140. The third bottom wall 130 is axially spaced and disposed on the top side of the second bottom wall 120 and the fifth bottom wall 150. The third bottom wall 130 is circumferentially disposed on one side of the first notch 171 and the part of the first side wall 170 located between the first notch 171 and the second notch 172. A first fan mounting port 131 is opened at the position corresponding to the second bottom wall 120 on the third bottom wall 130, and a communication opening is opened at the position corresponding to the fifth bottom wall 150 on the third bottom wall 130.

[0188] Here, side walls may be provided on the circumferential side of the second bottom wall 120. Side walls may be provided on the circumferential side of the fourth bottom wall 140. Side walls may be provided on the circumferential side of the fifth bottom wall 150.

[0189] Here, the first bottom wall 110, the second bottom wall 120, the third bottom wall 130, the fourth bottom wall 140, the fifth bottom wall 150, the first inclined wall 164, the second inclined wall 165, and the first side wall 170 may be different parts of the same structural member. For example, the first bottom wall 110, the second bottom wall 120, the third bottom wall 130, the fourth bottom wall 140, the fifth bottom wall 150, the first inclined wall 164, the second inclined wall 165, and the first side wall 170 may be integrally formed by injection molding to simplify the structure of the housing assembly 10. Of course, at least two of the first bottom wall 110, the second bottom wall 120, the third bottom wall 130, the fourth bottom wall 140, the fifth bottom wall 150, the first inclined wall 164, the second inclined wall 165, and the first side wall 170 may also be different structural members. At this time, the different structural members may be formed into an integral structure by welding or bonding.

[0190] In this implementation, as Figure 16 and Figure 17As shown, the second side wall 250 may have a third notch 251. The third notch 251 communicates with the drying cavity 351 and is located on the side close to the heating cavity 352. The third notch 251, the second notch 172, and the first notch 171 are arranged adjacent to each other in the circumferential direction along the rotation axis. The top shell 200 may further include: a first extension portion 280, a second top wall 220, a third top wall 230, and a fourth top wall 240. The first extension portion 280 extends outward from the first top wall 210 at the third notch 251 and extends out of the second side wall 250. The second top wall 220 is axially spaced below the first extension portion 280. An air outlet 293 is defined between the second top wall 220 and the first extension portion 280. The third top wall 230 is disposed on the outer periphery of the heating through hole 2121 and is connected to the second side wall 250. The third top wall 230 corresponds to the fifth bottom wall 150 in the axial position, and an air inlet cavity communicating with the through-connection opening is defined between the third top wall 230 and the fifth bottom wall 150. The third top wall 230 is provided with a second fan mounting opening 231. The fourth top wall 240 is disposed on the outer periphery of the heating through hole 2121 and is connected to the second side wall 250 through a third inclined wall and is adjacent to the third top wall 230. The fourth top wall 240 corresponds to the fourth bottom wall 140 in the axial position, and a condensation cavity is defined between the fourth top wall 240 and the fourth bottom wall 140. The condensation cavity communicates with the air inlet cavity. The axial distance between the fourth top wall 240 and the bottom shell 100 is greater than the axial distance between the first top wall 210 and the bottom shell 100.

[0191] Here, the first top wall 210, the first extension portion 280, the second top wall 220, the third top wall 230, the fourth top wall 240, the third inclined wall, and the second side wall 250 may be different parts of the same structural member. For example, the first top wall 210, the first extension portion 280, the second top wall 220, the third top wall 230, the fourth top wall 240, the third inclined wall, and the second side wall 250 may be integrally formed by injection molding to simplify the structure of the housing assembly 10. Of course, at least two of the first top wall 210, the first extension portion 280, the second top wall 220, the third top wall 230, the fourth top wall 240, the third inclined wall, and the second side wall 250 may also be different structural members. In this case, the different structural members may be formed into an integral structure by welding or bonding.

[0192] In this implementation, as Figure 11 shown, the housing assembly 10 may further include: a cover shell 310, a wind guide shell 320, and a heater shell 330; as Figure 12 shown, the drying device may further include: a first fan 820, a second fan 830, a heater 840, and a condenser 850 disposed in the condensation cavity.

[0193] As Figure 23 and Figure 24As shown, the first fan 820 and the housing 310 can be fixedly connected by means such as bolts and snap structures. So that the first fan 820 and the housing 310 form an integral structure and are installed at the first fan installation opening 131. As Figure 14 and Figure 12 shown, the housing 310 can be fixed at the first fan installation opening 131 of the third bottom wall 130 by means such as bolts and snap structures. The air inlet 821 of the first fan corresponds to the position of the air inlet 166; the air outlet 822 of the first fan corresponds to the position of the first notch 171.

[0194] As Figure 24 shown, the circumference of the impeller 823 of the first fan 820 near the housing 310 is a rounded corner 824. The housing 310 has an air outlet inclined surface 312 corresponding to the air outlet 822 of the first fan. The air outlet inclined surface 312 is gently arranged so that the air outlet space of the impeller 823 of the first fan 820 near the housing 310 is gently arranged. For example, the slope of the air outlet inclined surface is less than 30 degrees. As an example, the slope of the air outlet inclined surface 312 is less than 20 degrees. The gentle arrangement of the air outlet inclined surface 312 at the air outlet of the housing 310 can avoid the generation of eddy currents when the fluid passes through, thereby improving the air output. The rounded corner 824 of the circumference of the impeller 823 can, on the one hand, ensure the safety clearance between the air outlet inclined surface 312 and the circumference of the impeller 823, and on the other hand, reduce the noise generated when the impeller 823 rotates at high speed.

[0195] In the related technology, in order to ensure the safety clearance between the inclined surface of the fan volute air outlet and the circumference of the impeller, the inclined surface of the fan air outlet is often designed to be relatively steep, and at the same time, the circumference of the impeller does not have a rounded corner, resulting in a small air output and a large noise. The inventor of the present application has found through a large number of experiments that when the inclined surface of the air outlet is relatively steeply arranged, eddy currents are likely to be generated when the fluid passes through, resulting in a small air output. In the present application, the circumference of the impeller 823 of the first fan 820 near the housing 310 is a rounded corner 824, so that the air outlet inclined surface 312 can be gently arranged, which can not only ensure the safety clearance between the air outlet inclined surface 312 and the circumference of the impeller 823, but also reduce the noise generated when the impeller 823 rotates at high speed.

[0196] Here, part of the first bottom wall 110, part of the first side wall 170, part of the moisture absorption component 40 and the first convex arm 115 define the first humid cavity 341. Part of the first top wall 210, part of the first side wall 170, part of the moisture absorption component 40 and the second convex arm 214 define the drying cavity 351. The air inlet 166 is connected to the first humid cavity 341 through the first fan 820, so that the humid and hot air enters the first humid cavity 341, becomes dry air after passing through the moisture absorption component 40 and enters the drying cavity 351, and the dry air is led out by the air outlet 293.

[0197] When the first fan 820 is operating, the humid air sequentially enters the first humid cavity 341 through the air inlet 166, the air inlet 821 of the first fan, the air outlet 822 of the first fan, and the first notch 171. The humid air becomes dry air after passing through the moisture absorption component 40 and enters the dry cavity 351. The dry air is discharged through the air outlet 293. Here, the moisture absorption component 40 absorbs the moisture in the humid air.

[0198] Here, a part of the first fan 820 can extend from the first fan installation opening 131 towards the third bottom wall 130 side, so that the air inlet 821 of the first fan corresponds to the position of the air inlet 166, and the air outlet 822 of the first fan corresponds to the position of the first notch 171.

[0199] Here, the wall body of the bottom shell 100 located on the peripheral side of the third bottom wall 130 is located on the peripheral side of the first fan 820, so that the area where the first fan 820 corresponds to the first notch 171 forms the air outlet 822 of the first fan.

[0200] As Figure 11 and Figure 12 shown, the second fan 830 can be fixed to the second fan installation opening 231 of the third top wall 230 by means of bolts, snap structures, etc. The air inlet 831 of the second fan communicates with the condensation cavity through the air inlet cavity at the second fan installation opening 231.

[0201] Here, as Figure 25 and Figure 26 shown, the housing of the first fan 820 has defined the air inlet 831 and the air outlet 832 of the second fan. After installation, the second fan 830 can be located on the top side of the third bottom wall 130. The air inlet 831 of the second fan communicates with the condensation cavity through the air inlet cavity at the second fan installation opening 231, and the air outlet 832 of the second fan is located on the top side of the third bottom wall 130.

[0202] As Figure 18 and Figure 19 shown, the heater housing 330 can include: a fan-shaped top wall 331 and an annular side wall 332 connected to the peripheral side of the fan-shaped top wall 331. The fan-shaped top wall 331 and the annular side wall 332 are concave inward at the rotation axis to form a fan-shaped groove 333. The fan-shaped top wall 331 and the annular side wall 332 are provided with an air inlet side port 334 on the side opposite to the fan-shaped groove 333. The fan-shaped top wall 331 and the annular side wall 332 define a heater installation groove 335. One end of the annular side wall 332 away from the fan-shaped top wall 331 also defines a notch 3351 of the heater installation groove 335. The heater 840 can be fixed in the heater installation groove 335 by fixing structures such as bolts, snap structures, and bracket structures. As Figure 11 and Figure 12As shown, the heater housing 330 is installed at the heating groove 211, and a part of the annular side wall 332 located on the periphery of the notch 3351 is inserted into the heating through hole 2121, so that the heater 840 corresponds to the position of the heating through hole 2121, so that the hot air heated by the heater 840 can smoothly flow through the moisture absorption component 40 along the notch 3351 of the heater installation groove 335.

[0203] Here, a part of the first bottom wall 110, a part of the first side wall 170, a part of the moisture absorption component 40, and the first convex arm 115 define a second humid cavity 342, and the heater housing 330 and a part of the moisture absorption component 40 define a heating cavity 352; the air from the second fan 830 enters the heating cavity 352, absorbs the moisture desorbed by the moisture absorption component 40 after being heated and becomes humid air, the humid air enters the second humid cavity 342, and passes through the second notch 172 into the condensation cavity and is condensed into dry air by the condenser 850, and then enters the heating cavity 352 through the second fan 830, so as to circulate, so as to realize that the moisture absorption component 40 repeatedly has the ability to absorb moisture.

[0204] Here, the fan-shaped top wall 331 and the annular side wall 332 can be different parts of the same structural member. For example, the fan-shaped top wall 331 and the annular side wall 332 can be formed into an integral structure by injection molding. Another example is that the fan-shaped top wall 331 and the annular side wall 332 can also be different structural members. At this time, the fan-shaped top wall 331 and the annular side wall 332 can be fixedly connected by welding, bonding and other methods.

[0205] Here, the drying device can also include a wind guide plate 870. The wind guide plate 870 can be fixed in the heater installation groove 335 by means of screws, snap structures, welding, etc. The wind guide plate 870 is located on the side of the heater 840 away from the bottom case 100. The wind guide plate 870 has at least two wind guide holes 871. The air entering from the air inlet side port 334 is introduced into the heater 840 through the wind guide holes 871 of the wind guide plate 870, which can make the air entering from the air inlet side port 334 contact the heater 840 more evenly.

[0206] As Figure 12 and Figure 21 shown, the air guide housing 320 is arranged between the heater housing 330 and the second fan 830; the inlet 321 of the air guide housing 320 is communicated with the air outlet 832 of the second fan, and the outlet 322 of the air guide housing 320 is communicated with the air inlet side port 334; so that the air at the air outlet 832 of the second fan enters the air inlet side port 334 through the inlet 321 of the air guide housing 320, the cavity of the air guide housing 320 and the outlet 322 of the air guide housing 320.

[0207] Here, as Figure 22 and Figure 26As shown, the shape of the inlet 321 of the air guide housing 320 is the same as or substantially the same as the shape of the air outlet 832 of the second fan, such as Figure 22 and Figure 18 As shown, the shape of the outlet 322 of the air guide housing 320 is the same as or substantially the same as the shape of the air inlet side port 334.

[0208] In this implementation, as Figure 18 and Figure 19 shown, the heater housing 330 may further include a connecting flange 336; the drying device may further include: a first sealing ring 861 and a second sealing ring 862; the connecting flange 336 is disposed on the outer periphery of the annular side wall 332, and the air inlet side port 334 is located on the top side of the connecting flange 336; the outer periphery of the connecting flange 336 is wrapped with the first sealing ring 861, and the first sealing ring 861 is pressed between the connecting flange 336 and the second bottom 212; the outer periphery of the air inlet side port 334 is wrapped with the second sealing ring 862, and the second sealing ring 862 is pressed between the heater housing 330 and the air guide housing 320, as Figure 21 shown.

[0209] Here, the radius of the top side of the arc-shaped wall body 3321 on the side of the annular side wall 332 opposite to the fan-shaped groove 333 may be smaller than the radius of the bottom side, so that the arc-shaped wall body 3321 on the side of the annular side wall 332 opposite to the fan-shaped groove 333 forms a stepped shape. Of course, in other examples, the radius of the top side of the arc-shaped wall body 3321 on the side of the annular side wall 332 opposite to the fan-shaped groove 333 may also be greater than or equal to the radius of the bottom side.

[0210] Here, the materials of the first sealing ring 861 and the second sealing ring 862 are not limited. For example, the materials of the first sealing ring 861 and the second sealing ring 862 may be rubber.

[0211] In this implementation, the connecting flange 336 may be provided with third through holes 3361 and fourth through holes 3362 arranged at intervals; the third through holes 3361 and the fourth through holes 3362 are located on opposite sides of the arc-shaped wall body 3321, as Figure 19 and Figure 20 shown; the third through holes 3361 are located closer to the housing 310 side; the air guide housing 320 is provided with a fifth through hole 323 and a sixth through hole 324, the fifth through hole 323 corresponds to the position of the third through hole 3361, and the sixth through hole 324 corresponds to the position of the fourth through hole 3362, as Figure 21 and Figure 22As shown; the top shell 200 may further include: a connecting ear portion 291 and a first connecting column 292. The connecting ear portion 291 is disposed on the outer side of the second side wall 250; a seventh through hole 2911 is formed in the connecting ear portion 291, and the position of the seventh through hole 2911 corresponds to that of the third through hole 3361; the first connecting column 292 is disposed on the outer side of the second side wall 250; a third connecting hole 2921 is formed in the first connecting column 292, as Figure 16 shown; the position of the third connecting hole 2921 corresponds to that of the fourth through hole 3362; the first connecting column 292 sequentially passes through a part of the fourth through hole 3362 and the sixth through hole 324; the bottom shell 100 may further include: a second connecting column 190, the second connecting column 190 is disposed on the top side of the third bottom wall 130, as Figure 14 shown; the second connecting column 190 has a fourth connecting hole 191; the position of the fourth connecting hole 191 corresponds to that of the third through hole 3361; the second connecting column 190 sequentially passes through a part of the seventh through hole 2911, the third through hole 3361 and the fifth through hole 323; the drying device may further include: a second fastener 880 and a third fastener 890; the part of the second fastener 880 passing through the sixth through hole 324 is connected to the third connecting hole 2921; the third fastener 890, the part passing through the fifth through hole 323 is connected to the fourth connecting hole 191, as Figure 11 and Figure 12 shown.

[0212] Here, the second fastener 880 passes through and connects the air guide shell 320, the heater shell 330 and the top shell 200 at the same time, and the third fastener 890 passes through and connects the air guide shell 320, the heater shell 330, the top shell 200 and the bottom shell 100 at the same time, greatly simplifying the connection structure of the housing assembly 10. Of course, the drying device may also be provided with only one of the second fastener 880 and the third fastener 890; or, the drying device may also be fixed to the air guide shell 320, the heater shell 330, the top shell 200 and the bottom shell 100 by other screws, snap structures, etc.

[0213] Here, the third connecting hole 2921 and the fourth connecting hole 191 may be threaded holes, and the second fastener 880 and the third fastener 890 may be screws.

[0214] Here, the fan-shaped top wall 331, the annular side wall 332 and the connecting flange 336 may be different parts of a structural member. At this time, the fan-shaped top wall 331, the annular side wall 332 and the connecting flange 336 may be integrally formed by injection molding. Alternatively, the fan-shaped top wall 331, the annular side wall 332 and the connecting flange 336 may also be connected to form an integral structure by bonding, welding, etc.

[0215] In this implementation, as Figure 14 and Figure 15As shown, the bottom shell 100 may further include: two first limiting walls 181 and two second limiting walls 182. The two first limiting walls 181 are spaced apart in a first direction on the fourth bottom wall 140; the two second limiting walls 182 are spaced apart in a second direction on the fourth bottom wall 140; an installation space 183 is defined between the two second limiting walls 182 and the two first limiting walls 181; the two second limiting walls 182 and the two first limiting walls 181 define right-angle clamping slots 184 at four corners of the installation space 183; wherein, the second direction is perpendicular to the first direction; the condenser 850 includes a condensation body 851 and four clamping walls 852; the condensation body 851 is located within the installation space 183; the four clamping walls 852 are arranged along the axial direction at the four edges of the condensation body 851 and are respectively inserted into the four right-angle clamping slots 184, as Figure 12 shown; when installing the condenser 850, it only needs to insert the condenser 850 into the installation space 183 from the top side to the bottom side. At this time, since the four clamping walls 852 are respectively inserted into the four right-angle clamping slots 184, the condenser 850 can be stably limited within the installation space 183, with a simple structure and convenient disassembly and assembly.

[0216] Meanwhile, installing the condenser 850 between the top shell 200 and the bottom shell 100 can also greatly simplify the structure of the housing assembly 10. Of course, in other examples, the housing assembly 10 may also include an independent condenser 850 housing structure.

[0217] Here, the four clamping walls 852 are respectively inserted into the four right-angle clamping slots 184 means that each clamping wall 852 is inserted into one right-angle clamping slot 184.

[0218] Here, the first limiting wall 181 and the second limiting wall 182 may be an integral structure. Of course, the first limiting wall 181 and the second limiting wall 182 may also be formed by multiple sub-wall bodies.

[0219] Here, the first limiting wall 181, the second limiting wall 182 and the bottom shell 100 may be different parts of a structural member. At this time, the first limiting wall 181, the second limiting wall 182 and the bottom shell 100 may be integrally formed by injection molding. Alternatively, the first limiting wall 181, the second limiting wall 182 and the bottom shell 100 may also be connected to form an integral structure by bonding, welding or other means.
