[0033] It should be pointed out that unless otherwise specified, all technical and scientific terms used in the present application have the same meaning as commonly understood by those of ordinary skill in the technical field to which the present application belongs.

[0034] In the present invention, unless otherwise specified, the orientation terms such as "upper" and "lower" generally refer to the directions shown in the drawings, or to the vertical, perpendicular or gravitational directions; similarly, for ease of understanding and description, "left" and "right" generally refer to the left and right shown in the drawings; "inner" and "outer" refer to the inner and outer of the contour of each component itself, but the above orientation terms are not used to limit the present invention.

[0035] In order to solve the problem in the prior art that when a user or a staff member operates on the internal components of a drying device, it is easy to touch an electrical component and an electric shock accident occurs, the present application provides a drying device.

[0036] As Figures 1 to 12 shown, the drying device includes a housing assembly 10, a fan assembly 20, a heating device 30 and an electrical component 40. The housing assembly 10 has an air inlet hole 11, a first accommodation cavity 12, a second accommodation cavity 13 and an air outlet hole 14, and the air inlet hole 11 communicates with the air outlet hole 14 through the first accommodation cavity 12. The fan assembly 20 is disposed in the first accommodation cavity 12 for conveying the airflow located at the air inlet hole 11 into the air outlet hole 14. The heating device 30 is disposed in the first accommodation cavity 12 for heating the airflow entering the first accommodation cavity 12. The electrical component 40 is disposed in the first accommodation cavity 12. Wherein, the first accommodation cavity 12 and the second accommodation cavity 13 are independently arranged, and the second accommodation cavity 13 is used for accommodating accessories, and the accessories include an air outlet pipe 50.

[0037] Applying the technical solution of this embodiment, the fan assembly 20, the heating device 30 and the electrical component 40 are all installed in the first accommodation cavity 12, the air outlet pipe 50 can be stored in the second accommodation cavity 13, and the first accommodation cavity 12 and the second accommodation cavity 13 are independently arranged. In this way, when it is necessary to take out or place the air outlet pipe 50, the user or the staff member only needs to disassemble the housing assembly 10 to expose the air outlet pipe 50, and will not touch the electrical component 40. Furthermore, the independent arrangement of the air outlet pipe 50 and the electrical component 40 in the housing assembly 10 is realized, and the problem in the prior art that when a user or a staff member operates on the internal components of a drying device, it is easy to touch an electrical component and an electric shock accident occurs is solved. It can not only prevent the user or the staff member from touching or affecting the fan assembly 20, the heating device 30 and the electrical component 40 when operating the air outlet pipe 50, but also achieve the effect of electrical isolation, prevent the user from getting an electric shock during the process of taking out or placing the air outlet pipe 50, and thus improve the use safety of the user.

[0038] As Figures 1 to 3As shown, the housing assembly 10 includes a housing 15, a first cover plate 16, and a second cover plate 17. An air inlet hole 11 and an air outlet hole 14 are both provided on the housing 15. The first cover plate 16 is covered on the first side of the housing 15 to form a first accommodation cavity 12 with the housing 15. The second cover plate 17 is covered on the second side of the housing 15 to form a second accommodation cavity 13 with the housing 15. Wherein, the first side and the second side are oppositely arranged. In this way, the above settings make the fan assembly 20, the heating device 30, and the electrical component 40 all located on the first side, and the air outlet pipe 50 is located on the second side. Then, the electrical component 40 and the air outlet pipe 50 are independently arranged to achieve the effect of electrical isolation, so that the interior of the housing assembly 10 is a sandwich structure, separating the electrical component 40 from the structural components (such as the air outlet pipe 50, the fan assembly 20, and the heating device 30), thereby ensuring the electrical safety during the use of the internal parts to meet the requirements of a simple waterproof level. At the same time, the above settings make the structure of the housing assembly 10 simpler, easier to process and implement, reduce the processing cost of the housing assembly 10, and also make the internal space of the housing assembly 10 be reasonably utilized.

[0039] Specifically, the first cover plate 16 is detachably covered on the first side of the housing 15, and the second cover plate 17 is detachably covered on the second side of the housing 15, so that the interior of the housing assembly 10 is a sandwich structure. When maintenance is required for the fan assembly 20, or the heating device 30, or the electrical component 40, only the first cover plate 16 needs to be removed from the housing 15 to expose the parts to be maintained. At this time, the air outlet pipe 50 located in the second accommodation cavity 13 is not affected by the maintenance. When the air outlet pipe 50 needs to be taken in or out, only the second cover plate 17 needs to be removed from the housing 15. At this time, the parts located in the first accommodation cavity 12 are not affected.

[0040] As Figure 5 and Figure 6 shown, the housing 15 has a first recess 151 communicating with the air inlet hole 11, and the first recess 151 is used for installing the fan assembly 20. The first accommodation cavity 12 includes a first sub-chamber 121 and a second sub-chamber 122. The housing assembly 10 further includes a third cover plate 18. The third cover plate 18 is covered on the first recess 151 to form the first sub-chamber 121 with the first recess 151, and the fan assembly 20 is arranged in the first sub-chamber 121. Wherein, the third cover plate 18, the housing 15, and the first cover plate 16 surround to form the second sub-chamber 122, and the electrical component 40 is arranged in the second sub-chamber 122. In this way, after the fan assembly 20 is started, the gas outside the housing assembly 10 enters the first recess 151 under the suction of the fan assembly 20 to ensure that the fan assembly 20 can intake air normally. At the same time, the above settings make the fan assembly 20 and the electrical component 40 independently arranged, thereby avoiding the maintenance of the electrical component 40 from affecting the structural temperature of the fan assembly 20 and subdividing the interior of the housing assembly 10.

[0041] Specifically, the third cover plate 18 is connected to the casing 15 through fasteners, so that the first recess 151 and the third cover plate 18 form a first sub-chamber 121 for accommodating the fan assembly 20. The electrical component 40 is installed on the third cover plate 18 to prevent the electrical component 40 from shifting or moving in the housing assembly 10 and affecting the structural stability of the drying device.

[0042] In this embodiment, the second sub-chamber 122 is arranged around the first recess 151. In this way, the above arrangement makes the second sub-chamber 122 arc-shaped, so as to ensure that the air outlet pipe 50 can be accommodated in the second sub-chamber 122 when the air outlet pipe 50 is in the storage state, and avoid dust from falling on the air outlet pipe 50.

[0043] As Figure 1 and Figure 4 shown, the first cover plate 16 has a display area 161, and the electrical component 40 includes a main board 41 and a display board 42. Among them, at least part of the main board 41 is arranged on the third cover plate 18, and the main board 41 is electrically connected to the fan assembly 20 and the heating device 30. At least part of the display board 42 is arranged on the third cover plate 18 and is arranged opposite to the display area 161 for displaying the operating state of the drying device. Optionally, the operating state includes a drying state and a shutdown state. In this way, the above arrangement facilitates users or staff to obtain the operating state of the drying device in real time, thereby improving the user experience.

[0044] Specifically, electronic components such as resistors and capacitors are arranged on the main board 41 to adjust the operating state and operating parameters of the fan assembly 20 and the heating device 30 through the main board 41.

[0045] As Figures 5 to 8 shown, the casing 15 includes a casing body 152, a first surrounding plate 153 and a fourth cover plate 154. The air inlet hole 11 is arranged on the casing body 152. The first surrounding plate 153 is arranged on the casing body 152. The fourth cover plate 154 is covered on one side of the first surrounding plate 153 and forms a first recess 151 with the first surrounding plate 153. The fourth cover plate 154 has an air inlet 1541, and the air inlet 1541 is communicated with the first recess 151. Among them, the second accommodating cavity 13 is arranged around the first surrounding plate 153. In this way, the above arrangement makes the structure of the first recess 151 simpler, easier to process and implement, and reduces the processing cost of the drying device. At the same time, during the operation of the fan assembly 20, air can also enter through the air inlet 1541. On the one hand, it ensures that there is sufficient air flow in the drying device and improves the drying efficiency of the drying device; on the other hand, it cools down the fan assembly 20 to avoid the surface temperature of the fan assembly 20 being too high and affecting its service life.

[0046] Specifically, the first shroud 153 includes a straight plate section and an arc plate section that are connected to each other. The straight plate section is disposed closer to the heating device 30 than the arc plate section to ensure that the air flow can pass through the air outlet hole 14. At the same time, the above arrangement avoids the occurrence of turbulent flow of the air flow within the housing assembly 10, which may cause vibrations and noises during the operation of the drying device.

[0047] As Figure 6 and Figure 7 shown, the housing 15 further includes a second shroud 155. The second shroud 155 is connected to the first shroud 153 and is located on the second side of the housing 15. A power cord receiving cavity 156 is formed between the second shroud 155 and the first shroud 153. Wherein, at least a part of the first shroud 153, the second shroud 155 and at least a part of the housing body 152 surround to form a second recess, and the second recess and the second cover plate 17 form a second receiving cavity 13. In this way, the power cord receiving cavity 156 is used to accommodate the power cord 60, making the wiring within the housing assembly 10 neater and facilitating the disassembly and assembly of the drying device by the user or the staff.

[0048] Specifically, the extra part of the power cord 60 can be stored in the power cord receiving cavity 156. When the drying device is not in use, the entire power cord 60 is accommodated in the power cord receiving cavity 156, which is easy to store.

[0049] As Figure 3 shown, the housing assembly 10 further has a through hole 19, and the through hole 19 is used for the power cord 60 to pass through. In this way, the above arrangement ensures that the power cord 60 can pass through the through hole 19 and be connected to the power supply, thereby supplying power to the drying device.

[0050] Specifically, the housing 15 has a first opening, and the second cover plate 17 has a second opening. The first opening and the second opening are docked to form the through hole 19, making the processing of the through hole 19 easier and simpler, and reducing the processing cost of the drying device.

[0051] In this embodiment, the air outlet pipe 50 is detachably provided, having a use state mounted at the air outlet hole 14 and a storage state located within the second receiving cavity 13.

[0052] As Figures 4 to 6 shown, the drying device further includes a clamping portion 70. Wherein, the clamping portion 70 is provided on the housing 15 for clamping the power cord 60 and / or the wire 80. In this way, the clamping portion 70 is used to fix and guide the power cord 60 and / or the wire 80, making the wiring inside the drying device neater and not messy, and also making the internal space of the housing assembly 10 reasonably utilized, facilitating the staff to repair or maintain the circuit of the drying device.

[0053] Specifically, the above settings of the snap-in part 70 can ensure reliable guiding and fixing during circuit routing, guaranteeing the rational utilization of the internal space of the housing assembly 10 and keeping the routing neat.

[0054] As Figure 10 and Figure 11 shown, the fan assembly 20 includes a wind wheel 21 and a motor 22. Among them, the wind wheel 21 has a third recess 211. At least part of the motor 22 is located within the third recess 211, and the motor 22 is connected to the wind wheel 21 to drive the wind wheel 21 to rotate. In this way, the above settings enable part of the motor 22 to be hidden within the third recess 211, thereby reducing the overall occupied space of the fan assembly 20 and facilitating the internal structure layout of the drying device. At the same time, the above settings can utilize the airflow to dissipate heat from the motor 22, preventing the surface temperature of the motor 22 from being too high and affecting the service life of the motor 22.

[0055] As Figure 10 and Figure 11 shown, the wind wheel 21 includes a wind wheel body 212 and a plurality of air guiding vanes 214. Among them, at least part of the wind wheel body 212 is recessed inward to form the third recess 211, and ventilation holes 213 are provided on the inner surface of the third recess 211. The plurality of air guiding vanes 214 are arranged at intervals along the circumferential direction of the wind wheel body 212 on the wind wheel body 212. In this way, the structure of the above-set third recess 211 is simpler, easier to process and implement, reducing the processing cost of the fan assembly 20.

[0056] From the above description, it can be seen that the above embodiments of the present invention achieve the following technical effects:

[0057] The fan assembly, the heating device and the electrical components are all installed in the first accommodation cavity, the air outlet pipe can be accommodated in the second accommodation cavity, and the first accommodation cavity and the second accommodation cavity are independently arranged. In this way, when the air outlet pipe needs to be taken out or placed, the user or the staff only needs to disassemble the housing assembly to expose the air outlet pipe, without touching the electrical components. Thus, the independent arrangement of the air outlet pipe and the electrical components in the housing assembly is realized, solving the problem in the prior art that when the user or the staff operates on the internal parts of the drying device, it is easy to touch the electrical components and cause electric shock accidents. It can not only prevent the user or the staff from touching or affecting the fan assembly, the heating device and the electrical components when operating the air outlet pipe, but also achieve the effect of electrical isolation, preventing the user from getting an electric shock during the process of taking out or placing the air outlet pipe, thereby improving the user's safety in use.
