[0030] In addition, the technical features involved in different embodiments of the present application described below can be combined with each other as long as they do not conflict with each other.

[0031] In this embodiment, a first oscillating device is provided within the bellows portion of the heat pump module to adjust the air outlet angle of the heat pump module at the bellows outlet, thereby enabling the drying device to adjust the air outlet angle according to the type of clothing being dried. Furthermore, the first oscillating device can create an oscillating effect at the bellows outlet, thereby reducing the drying device's wind blind spots and improving the drying efficiency of the drying device.

[0032] The following describes the implementation of the present application in detail.

[0033] Please refer to Figures 1, 2 and 6. The unnumbered arrows in Figure 6 indicate the direction of air flow. The drying device 100 includes a housing 1 and a heat pump module 2. The housing 1 is provided with a storage space 11 and a revolving door 12. The storage space 11 can accommodate clothes to be dried, and the revolving door 12 is used to open or close the storage space 11. The heat pump module 2 includes a main unit part 21 and a bellows part 22 that are interconnected. The main unit part 21 is flat and is placed vertically on the back plate 111 of the storage space 11, wherein the back plate 111 is opposite to the revolving door 12. The bellows part 22 is flat and is placed at the bottom of the storage space 11, wherein one end of the bellows part 22 is connected to one end of the main unit part 21, and the heat pump module 2 is L-shaped. The main unit 21 is provided with a plurality of return air vents 211, each of which connects the interior of the heat pump module 2 with the storage space 11. A bellows outlet 22221 is provided at one end of the bellows unit 22, distal from the main unit 21. The bellows outlet 22221 connects the interior of the heat pump module 2 with the storage space 11. The heat pump module 2 is configured to draw air from the storage space 11 through the return air vents 221 and blow it out through the bellows outlet 22221, thereby forming an airflow within the storage space 11 and accelerating the evaporation of moisture from the clothing in the storage space 11. A first oscillating device 221 is also provided within the bellows unit 22. The first oscillating device 221 is located inside the bellows outlet 22221 and is configured to adjust the angle at which the heat pump module 2 discharges air at the bellows outlet 22221, thereby adjusting the air outlet angle according to the needs of the clothing to be dried. In addition, the first oscillating device 221 also has a cyclic oscillation function to form an oscillating effect at the bellows outlet 22221, thereby reducing the wind blind area and making the drying more uniform, thereby improving the drying efficiency of the drying device 100.

[0034] The flat shape mentioned in the embodiments of this application means that the thickness of the component in the first direction, along the normal direction of the component, does not exceed a predetermined thickness. The predetermined thickness can be set based on experience. For example, as shown in Figures 2, 4, and 6, the thickness of the main body portion 21 in the X direction is less than its height in the Y direction. The thickness of the bellows portion 22 in the Y direction is less than its length in the X direction.

[0035] In some embodiments, referring to Figures 2, 4, and 6, the host portion 21 includes a first housing 212, which is composed of a host rear cover 2121 and a host front cover 2122. The host front cover 2122 is provided with a first inclined surface 21221, and an inclined air inlet 21222 is provided on the first inclined surface 21221. The inclined air inlet 21222 connects the interior of the first housing 212 with the storage space 11, so that air in the storage space 11 can enter the first housing 212 through the inclined air inlet 21222. In this embodiment, by providing the inclined air inlet 21222 on the first inclined surface 21221, the risk of clothing completely blocking the inclined air inlet 21222 is reduced, ensuring that air in the storage space 11 can smoothly enter the first housing 21 through the inclined air inlet 21222. It is worth noting that there are multiple inclined air inlets 21222, and the multiple inclined air inlets 21222 are distributed in a rectangular array on the first inclined surface 21221. The multiple inclined air inlets 21222 constitute at least part of the return air inlet 211 of the main unit part 21, thereby ensuring that the return air inlet 211 has a sufficiently large cross-sectional area for air to enter the first shell 212, thereby ensuring that the air intake volume is large enough.

[0036] In some embodiments, the angle between the first slope 21221 and the back panel 111 of the accommodating space 11 is greater than 10° and less than 30°, so that the first slope 21221 is inclined relative to the height direction of the accommodating space 11. When the clothes to be dried are hung in the accommodating space 11, the clothes fall vertically, which helps to reduce the risk of the clothes completely blocking the inclined air inlet 21222, and ensure that air can smoothly enter the first shell 21 from the inclined air inlet 21222.

[0037] In some embodiments, referring to Figures 2, 4, and 6, a horizontal stepped surface 21223 is provided on the top of the main unit front cover 21222. The horizontal stepped surface 21223 is connected to the first inclined surface 21221. The horizontal stepped surface 21223 is provided with a horizontal air inlet 21224. The horizontal air inlet 21224 connects the interior of the first housing 212 with the accommodating space 11, so that air in the accommodating space 11 can enter the first housing 212 through the horizontal air inlet 21224. It is worth noting that there are multiple horizontal air inlets 21224, which are distributed in a rectangular array on the horizontal stepped surface 21223. The multiple horizontal air inlets 21224 and the multiple inclined air inlets 21222 together constitute all the return air ports 211 of the main unit 21. When the air in the storage space 11 enters the inclined air inlet 21222, the clothes will also swing toward the inclined air inlet 21222 along with the air flow. If the clothes are long, the clothes may block the inclined air inlet 21222. Therefore, in this embodiment, by providing a horizontal air inlet 21224 on the horizontal step surface 21223, the risk of the return air port 211 being completely blocked can be further reduced, ensuring that the air in the storage space 11 can smoothly enter the first shell 212. In other words, even if all the inclined air inlets 21222 on the first inclined surface 21221 are blocked by clothes under certain circumstances, the main unit 21 can still draw air from the horizontal air inlet 21224, thereby ensuring the normal operation of the drying device 100.

[0038] In some embodiments, referring to FIG. 2 , FIG. 4 and FIG. 6 , the first shell 212 is provided with a first air inlet channel 2123 , the bellows portion 22 is provided with a first air outlet channel 2223 , and the main unit portion 21 further includes a centrifugal wind turbine unit 213 . The inclined air inlet 21222 and the horizontal air inlet 21224 are both connected to one end of the first air inlet channel 2123, the air inlet of the centrifugal wind turbine unit 213 is connected to the other end of the first air inlet channel 2123, the air outlet of the centrifugal wind wheel assembly 213 is connected to one end of the first air outlet channel 2223, and the other end of the first air outlet channel 2223 is connected to the bellows air outlet 22221. The centrifugal wind turbine unit 213 is used to drive the air in the accommodating space 11 from the inclined air inlet 21222 and the horizontal air inlet 21224 into the first air inlet channel 2123, and then pass through the centrifugal wind turbine unit 213 and the first air outlet channel 2223 in turn and then be blown out from the bellows air outlet 22221.

[0039] In some embodiments, referring to Figures 2, 3, 4, and 6, a centrifugal wind turbine assembly 213 includes a centrifugal wind wheel 2131, a double-suction volute 2132, and a motor 2133. Two centrifugal wind wheels 2131 and two double-suction volutes 2132 are provided, and the two double-suction volutes 2132 are both installed in the first housing 212, and the two double-suction volutes 2132 are spaced apart. One centrifugal wind wheel 2131 is provided in one double-suction volute 2132, and the motor 2133 is provided between the two double-suction volutes 2132. The two centrifugal wind wheels 2131 are respectively connected to rotating shafts (not numbered) at both ends of the motor 2133, and the rotating shafts at both ends of the motor 2133 respectively drive the two centrifugal wind wheels 2131 to rotate. The air outlet of the double-suction volute 2132 is horizontally connected to the air inlet of the bellows portion 22. When the motor 2133 drives the two centrifugal impellers 2131 to rotate, the air in the accommodating space 11 is driven by the two centrifugal impellers 2131 to enter the first air inlet channel 2123 from the inclined air inlet 21222 and the horizontal air inlet 21224. The air then passes through the two double-suction volutes 2132 and the first air outlet channel 2223 in sequence before being blown out from the bellows air outlet 22221. In this embodiment, the provision of two centrifugal impellers 2131 and two double-suction volutes 2132 facilitates increasing the exhaust volume at the bellows air outlet 22221, thereby improving the drying efficiency of the drying apparatus 100.

[0040] In some embodiments, referring to Figures 2, 3 and 4, the double-suction volute 2132 is provided with a volute air outlet 21321 and two opposite volute air inlets 21322. The volute air outlet 21321 is connected to the first air outlet channel 2223. The volute air outlet 21321 constitutes the air outlet of the double-suction volute 2132. The air inlet of the bellows part 22 is located at one end of the first air outlet channel 2223 away from the bellows air outlet 22221. The air outlet of the double-suction volute 2132 is connected to the air inlet of the bellows part 22. There is a gap between the volute air inlet 21322 close to the motor 2133 in the double-suction volute 2132 and the motor 2133, and there is also a gap between the volute air inlet 21322 far away from the motor 2133 in the double-suction volute 2132 and the first shell 212. These gaps constitute the air inlet of the centrifugal wind turbine unit 213, so that when the motor 2133 drives the two centrifugal wind wheels 2131 to rotate, the air in the first air inlet channel 2123 can enter the double-suction volute 2132 from the two volute air inlets 21322 of the double-suction volute 2132, and then be blown out from the volute air outlet 21321 to the first air outlet channel 2223, and finally blown out from the bellows air outlet 22221 to the accommodating space 11.

[0041] In some embodiments, referring to Figures 2, 4, and 6, the bellows portion 22 further includes a second housing 222, which is formed by a bellows lower cover 2221 and a bellows upper cover 2222. A bellows outlet 22221 is provided on a side of the bellows upper cover 2222 away from the first housing 212. A bellows inlet 223 is provided on one side of the bellows portion 22. Two bellows inlets 223 are provided, forming the air inlet of the bellows portion 22. Both bellows inlets 223 are connected to the first air outlet channel 2223, and one bellows inlet 223 is connected to the volute outlet 21321 of a double-suction volute 2132, so that airflow in the two double-suction volutes 2132 can enter the first air outlet channel 2223 through the volute outlet 21321 and the bellows inlet 223. Wind guide ribs 22211 are provided on the bellows lower cover 2221 and are located in the first air outlet channel 2223 . The wind guide ribs 22211 can reduce the risk of vortex formation in the first air outlet channel 2223 , which is beneficial to reducing the loss of airflow in the first air outlet channel 2223 .

[0042] In some embodiments, referring to Figure 2, there are two air guide ribs 22211, one of which corresponds to one bellows air inlet 223, and the other corresponds to another bellows air inlet 223, thereby reducing the risk of vortex formation in the air flow entering the first air outlet channel 2223 from the two bellows air inlets 223, thereby reducing the loss of air flow in the first air outlet channel 2223.

[0043] In some embodiments, referring to FIG. 2 , the bellows portion 22 further includes a filter 224 , and the filter 224 covers the bellows air outlet 22221 .

[0044] In some embodiments, referring to Figures 2, 4, and 6, the first swinging device 221 includes a rotating air nozzle 2211 and a stepper motor 2212. The rotating air nozzle 2211 is rotatably mounted on the second housing 222 and is located inside the air outlet 22221 of the bellows. The stepper motor 2212 is mounted on the bellows 212, and the output shaft of the stepper motor 2212 is fixed to the rotating air nozzle 2211. The stepper motor 2212 is used to drive the rotating air nozzle 2211 to rotate, thereby adjusting the blowing direction at the bellows outlet 22221. In addition, the stepper motor 2212 can also drive the rotating air nozzle 2211 to swing cyclically along a preset angle, thereby forming a swinging effect, thereby reducing wind blind spots and achieving more uniform drying.

[0045] In some embodiments, the cross-section of the rotating air collecting nozzle 2211 includes an expanding air collecting portion 22111 and a contracting air pressure portion 22112. The expanding air collecting portion 22111 and the contracting air pressure portion 22112 transition gradually, and the airflow area of ​​the expanding air collecting portion 22111 is greater than the airflow area of ​​the contracting air pressure portion 22112. The expanding air collecting portion 22111 is connected to the first air outlet channel 2223, and the contracting air pressure portion 22112 is connected to the bellows air outlet 22221. When the airflow in the first air outlet channel 2223 flows through the rotating air collecting nozzle 2211, the gradual transition between the expanding air collecting portion 22111 and the contracting air pressure portion 22112 causes the airflow area of ​​the rotating air collecting nozzle 2211 to gradually decrease, thereby gradually increasing the airflow velocity, which is beneficial to improving the drying efficiency of the drying device 100.

[0046] In some embodiments, referring to Figures 4 and 6 , the main unit 21 further includes an evaporator 214 and a condenser 215 . The evaporator 214 is secured to the first housing 212 via an evaporator cover 2141 and is located inside the return air port 211 . The evaporator 214 absorbs heat from the air, condensing the moisture into water droplets, thereby forming dry air. The condenser 215 is secured to the first housing 212 via a condenser securing plate 2151 and is located below the evaporator 214 . The condenser 215 heats the air, thereby forming high-temperature, dry air. The high-temperature, dry air is driven by the centrifugal wind turbine assembly 213 into the first air outlet 2223 and then blown out from the bellows outlet 22221 . Furthermore, a triangular airflow channel is formed between the evaporator 214 and the condenser 215 . This means that after the air passes through the evaporator 214 , the airflow direction changes, slowing the airflow, which facilitates heating by the condenser 215 . In this embodiment, the evaporator 214 liquefies the moisture in the air in the storage space 11 and condenses it into water droplets, facilitating its timely discharge. The condenser 215 heats the air, thereby improving the drying efficiency of the drying device 100. Furthermore, by circulating the air in the storage space 11 within the storage space 11 and the heat pump module 2, there is no need to exhaust the humid air outside the storage space 11. This reduces the impact on the indoor air when the drying device 100 is placed indoors.

[0047] In some embodiments, referring to Figures 4, 5, and 6, the main unit 21 further includes a compressor 216 and a throttle 217. The evaporator 214, the compressor 216, the condenser 215, and the throttle 217 are connected in sequence by pipes to form a closed loop, in which a refrigerant circulates. The flow process of the refrigerant in the evaporator 214, the condenser 215, the compressor 216, and the throttle 217 is as follows: the liquid refrigerant evaporates into a gaseous state in the evaporator 214, at which point the evaporator 214 absorbs heat from the outside; the gaseous refrigerant flows into the compressor 216, which compresses the gaseous refrigerant to form a high-temperature, high-pressure refrigerant. The high-temperature, high-pressure refrigerant condenses into a low-temperature, high-pressure liquid refrigerant in the condenser 215, at which point the condenser 215 releases heat to the outside; the low-temperature, high-pressure refrigerant flows through the throttle 217 to form a low-temperature, low-pressure liquid refrigerant, completing the circulation of the refrigerant. The evaporator 214, condenser 215, compressor 216 and throttle 217 are all installed on the first shell 212. The evaporator 214 is located in the first air inlet channel 2123, and the first evaporator 214 is at least partially exposed to the inclined air inlet 21222 and the horizontal air inlet 21224. The condenser 215 is located in the first air inlet channel 2123, and the condenser 215 is arranged between the evaporator 214 and the centrifugal wind turbine unit 213. The compressor 216 is located in the first air inlet channel 2123. When the air in the storage space 11 contacts the wet clothes, it removes moisture from the clothes, forming humid air. The humid air enters the first air inlet 2123 through the inclined air inlet 21222 or the horizontal air inlet 21224. The evaporator 214 absorbs heat from the air, liquefying the moisture in the air and condensing it into water droplets, thereby forming dry air. When the dry air flows through the condenser 215, it absorbs the heat released by the condenser 215, forming high-temperature dry air. The high-temperature dry air passes through the first air outlet 2223 and is blown out of the bellows outlet 22221, causing the air to circulate within the storage space 11. In this embodiment, the evaporator 214 liquefies the moisture in the air in the storage space 11 and condenses it into dew droplets, facilitating the timely discharge of the moisture. The condenser 215 heats the air, thereby improving the drying efficiency of the drying device 100. In addition, by allowing the air in the storage space 11 to circulate in the storage space 11 and the heat pump module 2, there is no need to discharge the humid air out of the storage space 11. When the drying device 100 is placed indoors, the impact on the indoor air can be reduced.

[0048] In some embodiments, referring to Figures 4 and 6 , the main unit 21 further includes a water tray 218 , which is mounted on the first housing 212 and positioned below the evaporator 214 . When the evaporator 214 condenses moisture from the air into water droplets, the water droplets can drip into the water tray 218 . The water tray 218 is also connected to the outside of the drying apparatus 100 via a pipe, allowing for timely drainage of water. It is worth noting that the water tray 218 is positioned between the evaporator 214 and the condenser 215 to prevent water droplets from dripping onto the condenser 215 , which could lower the temperature of the condenser 215 and affect the generation of high-temperature airflow.

[0049] In some embodiments, referring to Figures 2, 4, and 6, a first housing 212 is mounted on the back panel 111 of the accommodating space 11, and the bellows portion 22 is mounted on the bottom of the accommodating space 11, wherein the back panel 111 is opposite the rotating door 12. The inclined air inlet 21222, the horizontal air inlet 21224, and the first air inlet channel 2123 are all disposed in the first housing 212. The centrifugal wind turbine assembly 213, the evaporator 214, the compressor 216, the condenser 215, and the throttle 217 are all mounted within the first housing 212. The bellows air outlet 22221 and the third air outlet channel 219 are both disposed in the bellows portion 22. In this embodiment, the compressor 216 and the centrifugal wind turbine unit 213 are both arranged in the first shell 212, and the bellows part 22 is only provided with a first air outlet channel 2223 and a bellows air outlet 22221. Therefore, in the height direction of the accommodating space 11, the height of the bellows part 22 is smaller than the height of the first shell 212. By installing the first shell 212 on the back plate 111 of the accommodating space 11 and installing the bellows part 22 on the bottom of the accommodating space 11, the space at the bottom of the accommodating space 11 can be released, the height of the accommodating space 11 can be lowered, and the height of the drying equipment 100 can be lowered. The space at the corner formed by the bottom of the accommodating space 11 and the back plate 111 is utilized, thereby improving the space utilization rate and helping to reduce the volume of the drying equipment 100.

[0050] For shirts, collars and cuffs are generally made of multiple layers of fabric, making the fabrics of the collars and cuffs thicker than other parts, resulting in the collars and two cuffs being more difficult to dry than other parts. The relevant drying equipment does not carry out targeted air drying on the collars and cuffs, resulting in the collars and cuffs taking longer to dry than other parts, which in turn leads to low drying efficiency.

[0051] To address the slow drying speed of collars and cuffs of shirts, as shown in Figures 6, 7, and 8, the drying device 100 further includes a top duct module 3. The top duct module 3 is provided with a first air outlet 311, a top air inlet 312, and a second air outlet 313. The second air outlet 313 and the first air outlet 311 are both connected to the top air inlet 312. The top air inlet 312, the second air outlet 313, and the first air outlet 311 are all connected to the storage space 11. Furthermore, the second air outlet 313 and the first air outlet 311 are oriented in different directions. In one embodiment, the opening of the first air outlet 311 is oriented toward the collar C, allowing the first air outlet 311 to blow air directly toward the collar C, thereby accelerating the drying speed of the collar C. The second air outlet 313 opens toward the bottom of the storage space 11 and is located at the end of the top duct module 3 away from the revolving door 12. The second air outlet 313 is used to blow air toward cuff B located away from the revolving door 12, thereby accelerating the drying of cuff A. Furthermore, the bellows portion 22 is located at the bottom of the storage space 11, and the bellows air outlet 22221 is disposed at the end of the bellows portion 22 away from the back panel 111. This allows the bellows air outlet 22221 to blow air toward cuff A located near the revolving door 12, thereby accelerating the drying of cuff A. In this embodiment, by providing the bellows air outlet 22221 in the heat pump module 2 and the second air outlet 313 and first air outlet 311 in the top duct module 3, air can be blown toward the clothes in the storage space 11 from at least three locations, thereby improving the drying efficiency of the drying apparatus 100. In addition, when the drying device 100 is drying shirts, the bellows air outlet 22221 is aimed at the cuff A on the side close to the revolving door 12, the first air outlet 311 is aimed at the collar C, and the second air outlet 313 is aimed at the cuff B on the side away from the revolving door 12, thereby speeding up the drying speed of the collar and cuffs, which are areas with thick fabrics, and further improving the drying efficiency of the drying device 100.

[0052] In some embodiments, referring to FIG6 , when airflow is simultaneously blown out from the bellows air outlet 22221, the first air outlet 311, and the second air outlet 313, the airflow tends to converge in the central region D of the receiving space 11, thereby concentrating humid air in the central region D. Therefore, the inclined air inlet 21222 is disposed at the end of the first inclined surface 21221 away from the bottom of the receiving space 11, and the horizontal air inlet 21224 is disposed at the top of the main body front cover 2122. That is, in the height direction of the receiving space 11, the return air port 211 formed by the inclined air inlet 21222 and the horizontal air inlet 21224 is substantially close to the central region D of the receiving space 11. This allows the humid air in the central region D to be promptly recovered from the return air port 211 and reentered into the first housing 212, thereby improving the drying efficiency of the drying device 100.

[0053] In some embodiments, referring to FIG6 , the angle between the first inclined surface 21221 and the back plate 112 is greater than 10° and less than 30°. When airflow is blown out from the bellows outlet 22221, the first air outlet 311, and the second air outlet 313 simultaneously, the airflow direction at the end is generally tilted downward. Therefore, by making the angle between the first inclined surface 21221 and the back plate 112 greater than 10° and less than 30°, the normal direction of the bellows outlet 22221 is tilted upward, which facilitates the airflow at the end to directly rush into the return air port 211, facilitating air recovery. It is worth noting that the airflow at the end is the airflow in the middle area D near the first inclined surface 21221.

[0054] In some embodiments, referring to Figures 4 and 6 , the evaporator 214 is positioned parallel to the first inclined surface 21221 and opposite the inclined air inlet 21222, so that the evaporator 214 faces and is close to the central area D where humid air is concentrated, allowing the moisture in the humid air to be promptly liquefied and condensed into water droplets. The condenser 215 is positioned perpendicular to the first inclined surface 21221 and below the evaporator 214. After the airflow passes through the evaporator 214, it is diverted and blown toward the condenser 215, slowing the airflow through the condenser 215 and facilitating the airflow to fully absorb heat from the condenser 215. Furthermore, after the airflow passes through the condenser 215, the cross-sectional area of ​​the first air inlet channel 2123 increases, reducing the wind resistance between the condenser 215 and the centrifugal wind turbine assembly 213 and facilitating the airflow into the centrifugal wind turbine assembly 213.

[0055] 6 , 8 and 9 , the top air duct module 3 includes a third housing 31 , a first fan 32 and a second fan 33 . The third housing 31 is installed at a corner formed by the back plate 111 and the top plate 112 of the accommodation space 11 . The first air outlet 311, the top air inlet 312 and the second air outlet 313 are all arranged in the third shell 31, and the first fan 32 and the second fan 33 are both installed in the third shell 31, and the inlet of the first fan 32 and the inlet of the second fan 33 are both connected with the top air inlet 312, the outlet of the first fan 32 is connected with the first air outlet 311, and the outlet of the second fan 33 is connected with the second air outlet 313. The first fan 32 is used to drive the air in the accommodating space 11 to enter the third shell 31 from the top air inlet 312 and blow out from the first air outlet 311, and the second fan 33 is used to drive the air in the accommodating space 11 to enter the third shell 31 from the top air inlet 312 and blow out from the second air outlet 313, wherein the directions of the second air outlet 313 and the first air outlet 311 are different from each other. In this embodiment, the first fan 32 drives air out of the first air outlet 311, and the second fan 33 drives air out of the second air outlet 313. This allows air to be blown simultaneously to at least two locations on the clothing within the storage space 11, thereby improving the drying efficiency of the drying device 100. For example, for a shirt, the second air outlet 313 can be directed toward the cuff B on the side away from the revolving door 12, while the first air outlet 311 can be directed toward the collar C. This can accelerate the drying speed of the cuffs and collar, thereby improving the drying efficiency of the drying device 100 for shirts. Furthermore, the corner formed by the back panel 111 and the top panel 112 of the storage space 11 is not occupied by clothing. Therefore, by installing the third housing 31 at the corner formed by the back panel 111 and the top panel 112 of the storage space 11, the hanging space at the top of the storage space 11 is not occupied, thereby improving the utilization of the storage space 11.

[0056] In some embodiments, the first air outlet 311 is arranged on the wind hole slope 314 of the third shell 31, and the angle between the wind hole slope 314 and the back panel 111 of the accommodating space 11 is greater than or equal to 30° and less than or equal to 70°, so that the first air outlet 311 can blow air at the position of the collar C.

[0057] In some embodiments, the angle between the air hole inclined surface 314 and the back plate 111 of the receiving space 11 is 45°.

[0058] In some embodiments, the second air outlet 313 is disposed on the first surface 315 of the third shell 31 , and the first surface 315 is perpendicular to the back panel 111 of the accommodating space 11 , so that the second air outlet 313 can blow air toward the cuff B.

[0059] In some embodiments, the third housing 31 is further provided with a second air inlet channel 316, a second air outlet channel 317, and a third air outlet channel 318. One end of the second air inlet channel 316 is connected to the top air inlet 312, the inlets of the first fan 32 and the second fan 33 are both connected to the other end of the second air inlet channel 316, the outlet of the first fan 32 is connected to one end of the second air outlet channel 317, the other end of the second air outlet channel 317 is connected to the second air outlet 313, the outlet of the second fan 33 is connected to one end of the third air outlet channel 318, and the other end of the third air outlet channel 318 is connected to the first air outlet 311.

[0060] In some embodiments, the top air duct module 3 also includes a first heating component 34, which is installed on the third shell 31, the first heating component 34 is accommodated in the second air outlet channel 317, and the first heating component 34 is located at the outlet of the first fan 32 to heat the air flowing through the second air outlet channel 317, thereby improving the drying efficiency of the drying device 100.

[0061] In some embodiments, the top air duct module 3 also includes a second heating component 35, which is installed on the third shell 31, the second heating component 35 is accommodated in the third air outlet channel 318, and the second heating component 35 is located at the outlet of the second fan 33 to heat the air flowing through the third air outlet channel 318.

[0062] In some embodiments, there are multiple second fans 33 and multiple second heating assemblies 35. Each of the multiple second fans 33 is mounted on the third housing 31 and spaced apart. The inlets of the multiple second fans 33 are connected to the second air inlet duct 316, and the outlets of the multiple second fans 33 are connected to the third air outlet duct 318. One second heating assembly 35 is located at the outlet of each second fan 33 to heat the air blown out from the second fan 33. By providing multiple second fans 33 and second heating assemblies 35, the wind force blown out from the second air outlet 313 can be increased, thereby improving the drying efficiency of the drying device 100.

[0063] In some embodiments (not shown), the first heating assembly 34 may also be disposed in the second air inlet passage 316. In this case, the second heating assembly 35 may not be required, and hot air may be blown out of the first air outlet 311. In this embodiment, by disposing the first heating assembly 34 in the second air inlet passage 316, there is no need to dispose heating assemblies in both the second air outlet passage 317 and the third air outlet passage 318, thereby simplifying the structure of the top air duct module 3.

[0064] In some embodiments, not shown in the figure, the top air duct module 3 also includes a second swinging device, which is arranged in the second air outlet channel 317.
