Description

Technical Field

[0001] This invention belongs to the technical field of clothing drying equipment, specifically, it relates to a portable clothing drying device. Background Technology

[0002] When customers travel for business or leisure, they often face the situation where clothes cannot be dried quickly after washing. Moreover, the clothes that usually need to be dried are small items such as underwear and socks.

[0003] While some hotels provide drying equipment such as clothes dryers, these devices are used by multiple people, raising hygiene concerns if used to dry underwear. Furthermore, home dryers, such as household dryers or small countertop dryers, are too small and heavy to be taken on business trips or travel.

[0004] Some users choose to use a hair dryer to dry their clothes, but this requires holding the hair dryer for a long time, which is time-consuming and laborious. Moreover, most of the clothes that need to be dried are small items such as underwear and socks. Compared with the size of these clothes, the hot air blown by the hair dryer has a large diffusion area, which makes it easy to waste heat and further prolong the drying time.

[0005] In view of this, the present invention is hereby proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art and provide a portable clothes drying device that is easy to carry when traveling and does not require hand-held use.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows:

[0008] A portable clothes drying device includes a shell of a certain length, with an air inlet at the first end and an air outlet at the second end.

[0009] The housing has a support structure arranged along its length for supporting the housing on a placement plane.

[0010] Furthermore, the support structure includes a horizontal support surface disposed on the lower side of the housing;

[0011] Alternatively, the support structure may include a plurality of support protrusions disposed on the lower side of the housing; the support protrusions are distributed along the length direction of the housing, and the protruding ends of each support protrusion are coplanar.

[0012] Furthermore, the shell has a straight edge on at least one side of its cross-section, and the straight edges on the same side of multiple different cross-sections together constitute the support structure;

[0013] Preferably, the lower side of the cross-section has a straight edge;

[0014] More preferably, the upper edge of the cross-section is a curve that bulges upward in the middle, and the two ends of the curve are respectively connected to the two ends of the straight edge.

[0015] Furthermore, the housing is provided with a telescopic structure along its length for adjusting the distance between the air inlet and the air outlet;

[0016] Preferably, the retractable structure includes a corrugated structure disposed on the peripheral wall of the housing; on the lower side of the housing, multiple peaks of the corrugated structure together constitute the support structure.

[0017] Furthermore, the interior of the housing is provided with a garment hanging section; the garment hanging section is distributed at intervals along the length of the housing and connected to the troughs of the corrugated structure.

[0018] Furthermore, the outer periphery of the air inlet has a connecting portion extending outward from the housing for connecting to a blower that provides drying airflow into the housing; the inner diameter of the connecting portion gradually decreases along the airflow direction, at least in the region near its extended end.

[0019] Furthermore, the air inlet is provided with a flow guide grille; at least a portion of the grille plates of the flow guide grille are inclined toward the outer periphery of the air inlet along the airflow direction.

[0020] Furthermore, a clothing loading / unloading opening is provided at the second end of the housing, and a detachable end cap is provided on the clothing loading / unloading opening; the air outlet is provided on the end cap;

[0021] Preferably, the opening area of ​​the air outlet is smaller than the opening area of ​​the air inlet.

[0022] Furthermore, the outer periphery of the clothing loading and unloading port has an assembly portion extending outward from the outer side of the housing; the outer periphery of the end cap has a sleeve portion that fits onto the outer side of the assembly portion.

[0023] Preferably, the sleeve portion and the assembly portion are interference-fitted.

[0024] Furthermore, a sterilization component is provided in the outer periphery of the air inlet;

[0025] Preferably, the air inlet is located on the end wall of the first end of the housing, and the end wall has mounting holes on the outer periphery of the air inlet for mounting the sterilization component.

[0026] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0027] In this invention, the air inlet of the portable clothes dryer is used to receive the drying airflow. The drying airflow is confined within the housing and flows from the air inlet to the air outlet, which helps to improve drying efficiency. The housing has a support structure that can support the housing on a flat surface, eliminating the need for the user to hold the clothes while drying. The support device is arranged along the length of the housing, and the air inlet is located at one end of the housing. The blower device used to provide the drying airflow can also be placed on the same flat surface, eliminating the need for the user to hold it, making it more time-saving and labor-saving.

[0028] In this invention, the shell has a retractable structure, allowing users to adjust the distance between the air inlet and outlet to a suitable level based on the amount of laundry to be dried. This ensures that the clothes can be fully unfolded, guaranteeing the drying effect, while also reducing unused internal space and preventing heat waste, thus further improving drying efficiency. The corrugated structure enables the shell to extend in length and also allows for folding to reduce its volume, making it easy to carry when traveling.

[0029] In this invention, the connecting part at the air inlet has a structure with a gradually decreasing inner diameter. When it is connected to the air outlet of the blower, it can be easily adapted to air outlets of different sizes, improving the versatility of the portable clothes drying device and making it more convenient to use.

[0030] In this invention, a guide grille is provided at the air inlet. The structure of the grille pieces tilting outward can guide the drying airflow to disperse outward, thereby entering the interior of the shell more evenly and dispersedly. This helps to increase the contact area between the drying airflow and the clothes, and further improves the drying efficiency.

[0031] In this invention, a detachable end cap is provided on the housing for easy access to clothing. An air outlet is provided on the end cap, and the opening area of ​​the air outlet is controlled to be smaller than that of the air inlet. This allows the drying airflow entering the housing to fully heat the clothing inside, evaporating moisture and improving the efficiency of heat utilization in the drying airflow. The end cap is installed at the clothing access point using an interference fit, preventing the drying airflow from blowing the end cap open.

[0032] The specific embodiments of the present invention will now be described in further detail with reference to the accompanying drawings. Attached Figure Description

[0043] It should be noted that these accompanying drawings and textual descriptions are not intended to limit the scope of the invention in any way, but rather to illustrate the concept of the invention to those skilled in the art by referring to specific embodiments. Detailed Implementation

[0044] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions in the embodiments will be clearly and completely described below with reference to the accompanying drawings. The following embodiments are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0045] In the description of this invention, it should be noted that the terms "upper", "lower", "front", "rear", "left", "right", "vertical", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limiting this invention.

[0046] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.

[0047] like Figures 1 to 8 As shown, an embodiment of the present invention provides a portable clothes drying device for providing a drying chamber for placing clothes to be dried. It can be used in conjunction with a blower that can provide drying airflow to improve the drying efficiency and drying effect of clothes.

[0048] Specifically, the portable clothes drying device is mainly used for drying small items of clothing and features a small size that makes it easy to carry when traveling. As a specific implementation, the hairdryer used in conjunction with the portable clothes drying device can be a hair dryer capable of blowing hot air. Since most hotels are equipped with hair dryers, users only need to carry the portable clothes drying device when traveling to meet their need for quick clothing drying.

[0049] In this embodiment, the portable clothes drying device includes a housing 100 of a certain length, with a drying chamber formed inside the housing 100 for placing clothes. Specifically, the first end (i.e., the front end in the figure) of the housing 100 is provided with an air inlet 111, and the second end (i.e., the rear end in the figure) of the housing 100 is provided with an air outlet 201. The drying airflow provided by the blowing device is blown in through the air inlet 111 and flows from front to back inside the housing 100, causing the moisture in the clothes to evaporate and finally being discharged from the air outlet 201 with water vapor, thereby drying the clothes.

[0050] Because the drying airflow provided by the blower is confined to the inside of the housing 100, heat waste is reduced, drying efficiency is improved, and the drying time of clothes is shortened.

[0051] To avoid the inconvenience of users having to hold the portable clothes dryer or hairdryer during the drying process, this embodiment further adopts the following technical solution.

[0052] In this embodiment, the housing 100 is provided with a support structure 101 arranged along its length direction. The housing 100 can be supported on a placement plane by the support structure 101, so that the user does not need to hold the portable clothes drying device when using it.

[0053] In one specific implementation, the placement surface can be a desktop or a similar surface.

[0054] The support structure 101 is arranged along the length of the housing 100, meaning that when the housing 100 is placed on the placement plane, its length is substantially parallel to the placement plane. The air inlet 111 and air outlet 201 are respectively located at both ends of the housing 100. Therefore, the user does not need to hold the air blower; they can simply place the air blower on the same placement plane, allowing the drying airflow provided by the air blower to be blown into the housing 100 through the air inlet 111. The direction of the airflow entering the housing 100 through the air inlet 111 is the same as the direction of the airflow inside the housing 100 from the air inlet 111 to the air outlet 201, which reduces kinetic energy loss of the airflow, ensures airflow intensity, and thus improves drying efficiency.

[0055] Using the above solution, users can place the portable clothes drying device and the blower together on a table, without having to hold the housing 100 or the blower. They only need to turn on the blower to provide drying airflow into the housing 100 to achieve the drying effect of clothes, making it more convenient to use.

[0056] In one specific embodiment of this invention, the support structure includes a horizontal support surface disposed on the lower side of the housing. By using a support surface with a certain area as the support structure, the housing can be stably supported on the placement plane.

[0057] In another specific embodiment of this invention, the support structure 101 includes a plurality of support protrusions 102 disposed on the lower side of the housing 100. The support protrusions 102 are distributed along the length direction of the housing 100, and the protruding ends of each support protrusion 102 are coplanar. In this way, the protruding ends of each support protrusion 102 can simultaneously contact the placement plane, providing a stable support effect for the housing 100.

[0058] In a further embodiment, the cross-section of the housing 100 has a straight edge 103 on at least one side. By taking sections at multiple different locations along the length of the housing 100, multiple different cross-sections can be obtained. The straight edges 103 on the same side of the multiple cross-sections together constitute the support structure 101.

[0059] In one specific structure, the lower side of the cross-section of the shell 100 has a straight edge 103, while the upper edge of the cross-section is a curve that convexes upward in the middle, with the two ends of the curve connected to the left and right ends of the straight edge 103, respectively.

[0060] In a more specific structure, the shell 100 is approximately a semi-cylindrical structure, with a straight edge 103 on the lower side of its cross-section, and an arc curve connected to the upper side of the straight edge 103, the central angle of which is not less than 180°.

[0061] In a further embodiment, the housing 100 is provided with a telescopic structure along its length, which can be used to adjust the overall length of the housing 100, thereby changing the distance between the air inlet 111 and the air outlet 201.

[0062] In the above solution, by providing a retractable structure for the housing 100, the user can adjust the length of the housing 100 to a suitable amount of laundry, ensuring that the volume of the drying chamber inside the housing 100 matches the amount of laundry. This avoids the portable clothes dryer occupying excessive space while ensuring that the laundry can be fully extended inside the housing 100. Simultaneously, it reduces unused space inside the housing 100, thus improving drying efficiency.

[0063] In one specific embodiment, the retractable structure includes a corrugated structure 150 disposed on the periphery of the housing 100, and the overall length of the housing 100 can be adjusted by unfolding or folding the corrugated structure 150.

[0064] More specifically, the housing 100 is made of a flexible material, and the corrugated structure 150 can be completely folded when the portable clothes dryer is not in use, thereby reducing the overall size of the portable clothes dryer and making it more convenient for users to place it in their suitcases or other luggage for easy carrying.

[0065] With the above structure, on the lower side of the shell 100, the multiple wave peaks 151 of the corrugated structure 150 can serve as support protrusions 102, together forming a support structure 101 for supporting the shell 100.

[0066] It should be noted that, in the description of this invention, the crests 151 and troughs 152 of the corrugated structure 150 are defined in terms of the shape of the outer side of the housing 100. Specifically, on the outer side of the housing 100, the highest point of the protrusion of the corrugated structure 150 is the crest 151, and the lowest point of the depression is the trough 152.

[0067] It is understood that other retractable structures capable of adjusting the shell length can also be applied in this embodiment. For example, the shell includes a multi-layer nested structure, with the inner layer extending out from the outer layer and retracting to achieve length adjustment.

[0068] In a further embodiment, a hanging section 160 is provided inside the housing 100. When in use, the clothes to be dried are hung on the hanging section 160 so that the clothes can be fully unfolded and achieve a better drying effect.

[0069] Specifically, the hanging part 160 is located in the upper region of the housing 100, with its upper end connected to the inner wall of the housing 100 and extending downward to form a hook. Multiple hanging parts 160 are spaced apart along the length of the housing 100, and a row of hanging parts 160 is provided on each of the left and right sides inside the housing 100. The lower ends of the left and right rows of hanging parts 160 are bent towards the middle region to form hooks.

[0070] In the above design, the upper end of the hanging part 160 is connected to the trough 152 of the corrugated structure 150. Since the trough 152 forms a protruding structure inside the shell 100, the hanging part 160, connected to the trough 152, is closer to the interior of the shell 100, thus avoiding obstruction of the hanging part 160 by the corrugated structure 150. On the other hand, since the hanging part 160 does not extend into the space between two adjacent troughs 152, it will not affect the folding of the corrugated structure 150, allowing the corrugated structure 150 to be compressed to its minimum volume when folded.

[0071] In one specific embodiment of this example, the shell 100 is an integral structure made of flexible material, preferably silicone, which can achieve structural folding, making it easy to carry, and also has the advantage of being lightweight.

[0072] In a further embodiment, the outer periphery of the air inlet 111 has a connecting portion 120 extending outward from the housing 100 for connecting to a blower, so that the drying airflow provided by the blower enters the interior of the housing 100 through the air inlet 111. The inner diameter of the connecting portion 120 gradually decreases along the airflow direction, at least in the region near its extended end.

[0073] Specifically, the connecting part 120 is an integral structure provided on the end wall 110 at the first end of the housing 100, and is also made of silicone material, which has a certain degree of elasticity. When the air outlet of the blower is inserted into the connecting part 120, the connecting part 120 can cover the air outlet of the blower to form a seal.

[0074] The inner diameter of the connecting part 120 gradually narrows from the front end to the rear, and preferably has a structure similar to a flared mouth. When a hair dryer is used as the blowing device, for hair dryers with different nozzle sizes, inserting the nozzle into the connecting part 120 to different depths can achieve a sealing fit with the connecting part 120. In this way, the connecting part 120 can be adapted to hair dryer nozzles of different sizes, making it more convenient to use.

[0075] In a more specific structure, in the rear end region of the connecting part 120, the inner diameter of the connecting part 120 gradually increases along the airflow direction, forming a small flared structure, which can play a certain role in diffusing the drying airflow, so that the drying airflow is blown into the interior of the shell 100 more evenly and dispersed, thereby increasing the contact area with the clothes.

[0076] In a further embodiment, a guide grille 130 is provided at the air inlet 111, and at least a portion of the grille plates of the guide grille 130 are inclined toward the outer periphery of the air inlet 111 along the airflow direction.

[0077] Specifically, the flow guide grille 130 has vertically arranged transverse grille plates 131 and longitudinal grille plates 132. The transverse grille plates 131 extend horizontally and are arranged in multiple intervals in the vertical direction. The longitudinal grille plates 132 extend vertically and are arranged in multiple intervals in the horizontal direction.

[0078] More specifically, the airflow grille 130 can be integrally formed with the housing 100.

[0079] In one specific implementation, one or more transverse grid plates 131 near the top are inclined upwards, forming a certain angle β with the horizontal plane. The remaining transverse grid plates 131 are parallel to the horizontal plane.

[0080] Of the multiple longitudinal grid plates 132, one or more longitudinal grid plates 132 near the left side are inclined to the left, forming an angle α with the airflow direction. One or more longitudinal grid plates 132 near the right side are inclined to the right, forming an angle α' with the airflow direction. The longitudinal grid plates 132 in the middle region are parallel to the airflow direction.

[0081] In one specific structure, the included angles α, α', and β are equal in size and controlled to be around 15°.

[0082] In this embodiment, the opening area of ​​the air inlet 111 is smaller than the cross-sectional area of ​​the housing 100. Using the above method, the drying airflow can diffuse outwards as it passes through the guide grille 130, thus more fully covering the cross-section of the housing 100. The guide grille 130 guides the drying airflow into the housing 100 more evenly and dispersedly, further increasing the contact area between the drying airflow and the clothes, and improving drying efficiency.

[0083] To facilitate the insertion and removal of clothing from the housing 100, a further embodiment of this solution provides a clothing insertion / removal port 140 at the second end of the housing 100, with a detachable end cap 200 on the clothing insertion / removal port 140. An air outlet 201 is located on the end cap 200.

[0084] When a user uses the portable clothes dryer to dry clothes, the end cap 200 covers the clothes loading / unloading port 140. The second end of the housing 100 is connected to the outside only through the air outlet 201, thereby expelling the humid air that has come into contact with the clothes from the housing 100. When it is necessary to put in or take out clothes, the user can remove the end cap 200 to open the clothes loading / unloading port 140, and then hang the clothes to be dried on the hanging part 160, or take the dried clothes off the hanging part 160 and take them out of the housing 100.

[0085] In a preferred embodiment, the upper and lower sides of the clothing loading / unloading opening 140 are close to the top and bottom of the housing 100, maximizing the opening area of ​​the clothing loading / unloading opening 140 to facilitate the user's clothing loading / unloading operations. The opening area of ​​the air outlet 201 is smaller than the opening area of ​​the air inlet 111, allowing the drying airflow entering the housing 100 to remain sufficiently inside the housing 100 to heat the clothing inside the housing 100, evaporate the moisture in the clothing, and improve the utilization efficiency of the heat in the drying airflow.

[0086] As a specific structure, the air outlet 201 is a circular opening located in the central area of ​​the end cover 200. The projection of the air inlet 111 on the end cover 200 from front to back completely covers the air outlet 201, which is conducive to the smooth discharge of the drying airflow from the housing 100.

[0087] As another specific structure, the air outlet includes a plurality of air vents spaced apart on the end cap. The opening area of ​​each individual air vent can be set to be relatively small, and the opening area of ​​the air outlet is the sum of the opening areas of all the individual air vents. This scheme, which uses multiple air vents to form the air outlet, reduces the opening area of ​​each individual air vent, thus preventing small items of clothing from being blown out.

[0088] Furthermore, the outer periphery of the clothing loading and unloading port 140 has an assembly portion 141 extending outward from the housing 100, and the outer periphery of the end cap 200 has a sleeve portion 210 that fits onto the outer side of the assembly portion 141.

[0089] Specifically, the assembly part 141 protrudes from the outer surface of the second end of the housing 100, and the main body of the end cap 200 covers the clothing opening 140, with its outer periphery extending toward the housing 100 to form a sleeve part 210. The sleeve part 210 is sleeved on the outside of the assembly part 141, fixing the end cap 200 to the clothing opening 140, making it convenient for the user to open and close the clothing opening 140.

[0090] In the preferred configuration, the sleeve portion 210 and the assembly portion 141 are assembled using an interference fit, which can more firmly fix the end cap 200 to the garment loading / unloading port 140. This prevents the end cap 200 from being blown open by the drying airflow during the garment drying process.

[0091] In a further embodiment, the portable clothes drying device is equipped with a sterilization component 300 to provide clothes sterilization function to meet hygiene requirements. Specifically, the sterilization component 300 is disposed on the housing 100, located in the outer peripheral area of ​​the air inlet 111.

[0092] By incorporating the sterilization component 300, sterilization can be achieved during the clothes drying process, ensuring the hygiene of the clothes after drying. In particular, the sterilization component 300 is located in the outer periphery of the air inlet 111, which can sterilize the incoming drying airflow near the air inlet 111, preventing secondary contamination of the clothes due to insufficiently hygienic drying airflow.

[0093] As a specific structure, the air inlet 111 is opened on the end wall 110 of the housing 100, and the end wall 110 is provided with a mounting hole 112 on the outer periphery of the air inlet 111, and the sterilization component 300 is disposed in the mounting hole 112.

[0094] More specifically, the mounting hole 112 is a through hole penetrating both the inner and outer sides of the housing 100. The sterilization component 300 is inserted into the mounting hole 112, with part of it located on the outer side of the housing 100 and part of it extending into the inner side of the housing 100. The end wall 110 is a curved surface that bulges forward, which allows for a certain amount of space to be reserved for the sterilization component 300 on the inner side of the end wall 110, thus avoiding interference between the corrugated structure 150 and the sterilization component 300 when the corrugated structure 150 is fully folded.

[0095] In one specific embodiment of this invention, the sterilization component 300 achieves a sterilization effect by emitting ultraviolet light and has an ultraviolet light source for emitting ultraviolet light. The ultraviolet light source extends into the inner side of the housing 100 and irradiates the interior of the housing 100 with ultraviolet light for sterilization.

[0096] In a more specific embodiment, the sterilization component 300 is detachably mounted in the mounting hole 112. The user can conveniently remove the sterilization component 300 from the mounting hole 112 for charging. When clothes need drying, the sterilization component 300 is reinserted into the mounting hole 112 to activate it. Preferably, the sterilization component 300 and the mounting hole 112 are assembled using an interference fit, ensuring a more secure and reliable installation of the sterilization component 300 and preventing it from easily detaching from the mounting hole 112.

[0097] In the above scheme, users can choose whether to turn on the sterilization component 300 according to their actual needs. However, when using the portable clothes dryer without sterilization, it is best to also install the sterilization component 300 at the mounting hole 112 to seal the mounting hole 112 and prevent the drying airflow from leaking out from the mounting hole 112.

[0098] The specific usage process of the portable clothes drying device provided in this embodiment is as follows.

[0099] When traveling or on business trips, users can use the corrugated structure 150 to compress and fold the shell 100 along its length. After folding and shrinking, it can be placed in a suitcase and carried at any time.

[0100] When clothes need drying, the user holds both ends of the housing 100 and pulls them apart in opposite directions to unfold the corrugated structure 150, then places the housing 100 on a table. Next, remove the end cap 200 from the second end of the housing 100 to open the clothes loading / unloading port 140. Hang the clothes to be dried on the hanging section 160 inside the housing 100 through the clothes loading / unloading port 140, ensuring the clothes are fully unfolded. After placing the clothes, replace the end cap 200 on the clothes loading / unloading port 140. The housing 100 can also be adjusted to a suitable length according to the amount of clothes.

[0101] Afterwards, the user can insert the air nozzle of the hair dryer into the front end of the connecting part 120, so that the inner peripheral wall of the connecting part 120 seals and wraps around the outside of the air nozzle of the hair dryer. After the hair dryer is connected to the housing 100, the hair dryer can also be placed on the table without the user having to operate it by hand.

[0102] Users can choose whether to activate the sterilization component 300 according to their actual needs, and then turn on the hair dryer to start drying clothes. The hot air blown out by the hair dryer serves as the drying airflow for drying clothes. This drying airflow enters the housing 100 through the guide grille 130, and disperses in all directions as it passes through the guide grille 130, thus blowing more evenly into the housing 100 and increasing the contact area with the clothes. The drying airflow flows from front to back inside the housing 100. After fully heating the clothes inside the housing 100, it carries the water vapor formed by the evaporation of moisture from the clothes and is discharged from the air outlet 201 on the end cover 200. The entire drying process does not require the user to hold the housing 100 or the hair dryer, saving the user's time. Because the drying airflow is confined to the inside of the housing 100, heat waste caused by the drying airflow dissipating in all directions is reduced, improving drying efficiency.

[0103] After the clothes are dried, the user can turn off the hair dryer, pull the air nozzle out from the inside of the connector 120, and then remove the end cap 200 to take out the dried clothes from inside the housing 100. After the clothes are removed, the user can push the two ends of the housing 100 together to fold the corrugated structure 150, which can compress the volume of the portable clothes drying device for easy storage.

[0104] The portable clothes drying device provided in this embodiment has a support structure 101 on the lower side of the housing 100, which can be placed on a table or other flat surface. It can be used in conjunction with a hair dryer or other air-blowing device to dry clothes. During the drying process, the air-blowing device is also placed on the same flat surface, eliminating the need for user support and freeing up the user's hands. The housing 100 has a foldable and extendable structure, making it easy to carry when folded, meeting the user's need for quick drying of small items of clothing during business trips or travel. The hot air provided by the air-blowing device serves as the drying airflow for drying clothes. The portable clothes drying device can confine the drying airflow within the housing 100, greatly improving the drying efficiency and effect of drying small items of clothing.

Although the present invention has been disclosed above with reference to preferred embodiments, it is not intended to limit the present invention. Any person skilled in the art can make some modifications or alterations to the above-described technical content to create equivalent embodiments without departing from the scope of the present invention. Any simple modifications, equivalent changes, and alterations made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the scope of the present invention.
