Description

Technical Field

[0001] This application relates to the field of daily necessities technology, and in particular to a clothes drying suitcase. Background Technology

[0002] During business trips, leisure travel, and other outings, users typically carry a limited number of clothes. When clothes are damp from washing, rain, sweat, or spot cleaning, they often need to be dried quickly so they can be worn again or stored away. This is especially true when traveling continuously, staying for a limited time, or in poorly ventilated accommodations. If damp clothes are not dried promptly, it not only affects the user experience but may also cause odors and build up moisture. Therefore, there is a significant need for quick clothes drying during travel.

[0003] To address the inconvenience of drying clothes during travel, current methods typically involve hanging clothes indoors to air dry naturally, or using air conditioning vents, bathroom heaters, or hair dryers for temporary drying. However, these methods generally have limitations in practice. For example, the hanging location is constrained by the accommodation environment; temporary drying using indoor equipment is unstable and unreliable; the process is cumbersome; and it's difficult to balance portability, ease of use, and drying efficiency. Therefore, they fail to adequately meet the need for quick clothing drying during travel. Summary of the Invention

[0004] One objective of this application is to provide a clothes drying suitcase that aims to solve the technical problem of the difficulty in quickly drying clothes during travel.

[0005] To achieve the above objectives, this application provides a clothes drying suitcase, including a suitcase body and a pull rod movably connected to the suitcase body. The pull rod has an extended state and a retracted state. The suitcase body has a storage cavity and a functional cavity. The storage cavity is used to hold clothes. The side of the suitcase body near the pull rod has a retrieval port communicating with the functional cavity. The clothes drying suitcase also includes: a blower module disposed in the functional cavity, the blower module having an air outlet; and a clothes drying bag with an air inlet communicating with the air outlet of the blower module. The clothes drying bag has an unfolded state and a folded state. In the folded state, the clothes drying bag is stored in the functional cavity. The retrieval port is used for the clothes drying bag to enter and exit the functional cavity. In the extended state, the pull rod is used to hang the clothes drying bag in the unfolded state.

[0006] The clothes-drying suitcase provided in this application includes a functional cavity separate from the storage cavity, a blower module located within the functional cavity, and a clothes-drying bag used in conjunction with the blower module. The clothes-drying bag has an unfolded state and a folded state. When the clothes-drying bag is in the folded state, it is stored in the functional cavity. In use, the clothes-drying bag is taken out of the functional cavity through the access port and unfolded, then hung on the pull rod in the extended state. The blower module delivers airflow through the air outlet to the air inlet of the clothes-drying bag. The airflow circulates inside the clothes-drying bag and acts on the clothes inside, thereby drying the clothes. After drying is complete, the clothes-drying bag is removed from the pull rod and folded, then stored back in the functional cavity through the access port. The pull rod can also be switched to the folded state, and the clothes-drying suitcase returns to its regular suitcase usage form.

[0007] Compared to existing technologies that rely on indoor structures as clothes hangers, this solution directly utilizes the existing pull rod of the suitcase as a support for the drying bag, eliminating environmental constraints for drying and airing clothes. Furthermore, this solution integrates the blower module and drying bag into a functional cavity within the suitcase, allowing for quick access via a slit. This compact integration of the drying components with the suitcase structure allows for easy drying by simply pulling out the drying bag. When not in use, the suitcase maintains its standard storage and portability. Additionally, the air inlet of the drying bag is directly connected to the air outlet of the blower module. Airflow enters the drying bag from the outlet and is concentrated within the relatively enclosed space, focusing on the surface of the clothes. This shorter airflow path and more concentrated airflow effectively improve drying efficiency. Users can quickly unfold the bag to dry clothes during travel and swiftly retract it afterward, making it convenient and suitable for travel, business trips, and other situations requiring temporary clothing drying.

[0008] According to one embodiment of this application, the pull rod includes a sliding part and a handle part, the two sliding parts are arranged in parallel, and the handle part is connected between the two sliding parts; the housing includes two sliding channels that are arranged one-to-one with the two sliding parts, the sliding parts extend along the height direction of the housing and are slidably connected in the sliding channels, and the functional cavity extends along the height direction of the housing and is located between the two sliding channels.

[0009] By arranging the functional cavity between the two sliding channels, the internal space of the cabinet that was originally not effectively utilized between the sliding parts of the two pull rods is fully utilized to accommodate the blower module and the dryer bag in the folded state, avoiding the drying components occupying the effective storage volume of the storage cavity. On the other hand, the longitudinal shape of the functional cavity extending along the height of the cabinet allows the dryer bag to be compactly stored longitudinally after folding, and also facilitates the smooth pulling out and putting in the dryer bag in this direction through the access port, avoiding the risk of interference between the pull rod and the dryer bag.

[0015] According to one embodiment of this application, the air inlet of the clothes drying bag is provided with an elastic closing part, which is sleeved around the air outlet of the blower module.

[0016] According to one embodiment of this application, the blower module has a mating groove surrounding the outer periphery of the air outlet, an elastic closing portion is embedded in the mating groove, and a sealing ring is provided between the elastic closing portion and the mating groove.

[0017] According to one embodiment of this application, the blower module further includes a heating unit for heating the airflow output from the air outlet.

[0018] According to one embodiment of this application, the dryer suitcase also includes a rechargeable battery disposed within the functional cavity and electrically connected to the blower module for supplying power to the blower module.

[0019] According to one embodiment of this application, the blowing module includes a centrifugal fan.

[0020] According to one embodiment of this application, a heat insulation plate and / or a waterproof plate are provided between the storage cavity and the functional cavity.

[0021] According to one embodiment of this application, the clothes drying bag is provided with a plurality of moisture venting holes, the density of which gradually increases in the direction away from the air inlet; and / or, the clothes drying bag is provided with a restraint for maintaining a folded state, the restraint being a strap, elastic band, snap, buckle, or Velcro.

[0022] According to one embodiment of this application, the clothes drying bag includes an air guide section and a drying section. In the unfolded state, the drying section of the clothes drying bag is hung on a pull rod in the pulled-out state.

Detailed Implementation

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this application, and not all of the embodiments. Based on the embodiments of this application, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this application.

[0029] Currently, suitcases are a common travel item for leisure and business trips. They typically consist of a box, wheels, and a handle, and are mainly used to store and transport clothing and personal belongings. During travel, users usually carry a limited number of clothes. When clothes are damp due to washing, rain, sweat, or spot cleaning, they often need to be dried quickly so they can be worn again or packed away. Under current conditions, users typically hang damp clothes indoors to air dry naturally, or use air conditioning vents, bathroom heaters, or handheld hair dryers in accommodations for temporary drying. These methods generally rely on existing facilities in the accommodation environment, and the lack of coordination between these facilities makes it difficult to balance portability and drying efficiency.

[0030] To solve the technical problem of quickly drying clothes while traveling, please refer to... Figures 1 to 5 As shown, this application discloses a dry suitcase, including a suitcase body 10 and a pull rod 20 movably connected to the suitcase body 10. The pull rod 20 has an extended state and a retracted state. The suitcase body 10 has a storage cavity 11 and a functional cavity 12. The storage cavity 11 is a cavity that realizes the basic storage function of the suitcase and is used to hold items. The type of items is not limited, such as clothing, shoes, hats, books, etc. The functional cavity 12 is a cavity that is additionally extended / separated in this embodiment compared to a regular suitcase. It is much smaller in volume than the storage cavity 11. The suitcase body 10 is located near the pull rod 20. The dryer suitcase has a side opening with a retrieval port 13 that communicates with the functional cavity 12. The dryer suitcase also includes: a blower module 30, which is located in the functional cavity 12 and has an air outlet 31; a dryer bag 40, which has an air inlet 41 that communicates with the air outlet 31 of the blower module 30. The dryer bag 40 has an unfolded state and a folded state. The folded dryer bag 40 is stored in the functional cavity 12. The retrieval port 13 is used for the dryer bag 40 to enter and exit the functional cavity 12. The pull rod 20 in the pulled-out state is used to hang the dryer bag 40 in the unfolded state.

[0031] The clothes-drying suitcase provided in this application includes a functional cavity 12 independent of the storage cavity 11, a blower module 30 disposed within the functional cavity 12, and a clothes-drying bag 40 used in conjunction with the blower module 30. The clothes-drying bag 40 has an unfolded state and a folded state. When the clothes-drying bag 40 is in the folded state, it is stored in the functional cavity 12. When in use, the clothes-drying bag 40 is taken out from the functional cavity 12 and unfolded through the access port 13, and hung on the pull rod 20 in the pulled-out state. The blower module 30 delivers airflow to the air inlet 41 of the clothes-drying bag 40 through the air outlet 31. The airflow circulates inside the clothes-drying bag 40 and acts on the clothes inside, thereby drying the clothes. After drying is complete, the clothes-drying bag 40 is removed from the pull rod 20 and folded, and then stored back in the functional cavity 12 through the access port 13. The pull rod 20 can also be switched to the storage state, and the clothes-drying suitcase returns to the use form of a regular suitcase.

[0032] Compared to existing technologies that require indoor structures as hanger points, this dryer suitcase offers two distinct states: a first state functioning as a regular suitcase and a second state for drying. It directly utilizes the existing pull rod 20 of the suitcase as a support for the drying bag 40, eliminating environmental constraints for drying and airing. Furthermore, this solution integrates the blower module 30 and the drying bag 40 within the functional cavity 12 of the suitcase body 10, allowing for quick access to the drying bag 40 via the access port 13. This compact integration of the drying components with the suitcase body 10 allows for easy drying by simply pulling out the drying bag 40, while maintaining the suitcase's standard storage and carrying capacity when the drying function is not in use. Additionally, the air inlet 41 of the drying bag 40 is directly connected to the air outlet 31 of the blower module 30. Airflow enters the drying bag 40 from the outlet 31 and concentrates on the clothing surface within the relatively enclosed space, resulting in a shorter airflow path and more concentrated airflow, effectively improving drying efficiency. Users can quickly unfold the device to dry clothes while traveling and quickly store it away after use. It is easy to operate and suitable for occasions such as travel or business trips where temporary clothes drying is required.

[0033] It should be noted that this embodiment does not limit the specific structural form, power type, and installation method of the blower module 30, the material, shape, size, and folding method of the drying bag 40, or the specific connection form between the air inlet 41 and the air outlet 31. For example, the blower module 30 can be a centrifugal fan, axial fan, cross-flow fan, or other air supply device capable of generating directional airflow. It can be fixedly installed in the functional cavity 12 by means of screw fastening, snap-fitting, or bonding. Preferably, it is installed in the functional cavity 12 in a detachable manner to facilitate maintenance or replacement. The power supply of the blower module 30 can be connected to the mains power through an external power cord, or it can be powered by a rechargeable battery built into the functional cavity 12, or it can be powered by an electronic device such as a power bank stored in the storage cavity 11. The drying bag 40 can be made of flexible fabrics such as nylon, polyester, and Oxford cloth, or of waterproof and breathable composite materials, PEVA film, etc. Its shape can be cylindrical, conical, square, or other suitable for holding clothes. The bag size can be adaptively designed according to the volume of the functional cavity 12 and actual drying needs. The drying bag 40 can be folded in half, rolled up, accordion folded, or any other method that reduces its volume to fit inside the functional cavity 12. The connection between the air inlet 41 of the drying bag 40 and the air outlet 31 of the blowing module 30 can be a direct connection, plug-in connection, or snap-fit ​​connection, or it can be indirectly connected through adapters, hoses, or other transitional parts, as long as the airflow output from the air outlet 31 can effectively enter the interior of the drying bag 40. Any technical solution that enables the blower module 30 to deliver airflow through the air outlet 31 to the air inlet 41 of the drying bag 40 and to make the airflow circulate inside the drying bag 40 and act on the clothes inside the bag, regardless of the specific structure of the blower module 30, the material and shape of the drying bag 40, the folding method or the connection form, can achieve the technical effect of rapid drying of clothes in this application, and should not be used to limit the scope of protection of this application.

[0034] Furthermore, this embodiment does not limit the air intake source or method of the blower module 30. When operating, the blower module 30 needs to continuously draw in air and output airflow through the air outlet 31. Its air intake source can be ambient air outside the housing 10, air inside the storage cavity 11, or air simultaneously drawn in from both the external environment and both sides of the storage cavity 11. Specifically, the blower module 30 can draw in air from the external environment through a one-way air intake valve located on the wall of the housing 10. This one-way air intake valve allows external air to be drawn in when the blower module 30 is operating, while preventing the hot and humid airflow in the functional cavity 12 from escaping through the valve after shutdown. Alternatively, the blower module 30 can draw in air from one side of the storage cavity 11 through an air intake pipe connecting the storage cavity 11 and the functional cavity 12; or, both an external air intake and an internal air intake channel can be simultaneously provided on the housing 10, allowing the blower module 30 to naturally draw in air from both sides according to the actual installation structure. Any air intake method that can provide a continuous and stable air intake source for the blower module 30 and enable it to output airflow normally is applicable to the technical solution of this application, and those skilled in the art can set it according to actual needs.

[0035] According to one embodiment of this application, the pull rod 20 includes a sliding part 22 and a handle part 21. The two sliding parts 22 are arranged in parallel, and the handle part 21 is connected between the two sliding parts 22. The housing 10 includes two sliding channels 23 that are arranged one-to-one with the two sliding parts 22. The sliding parts 22 extend along the height direction of the housing 10 and are slidably connected in the sliding channels 23. The functional cavity 12 extends along the height direction of the housing 10 and is located between the two sliding channels 23.

[0036] By arranging the functional cavity 12 between the two sliding channels 23, the internal space of the cabinet 10 that was originally not effectively utilized between the sliding parts 22 of the two pull rods 20 is fully utilized to accommodate the blower module 30 and the dryer bag 40 in the folded state, thus avoiding the drying components occupying the effective storage volume of the storage cavity 11. On the other hand, the longitudinal shape of the functional cavity 12 extending along the height direction of the cabinet 10 allows the dryer bag 40 to be compactly stored longitudinally after folding, and also facilitates the smooth extraction and insertion of the dryer bag 40 through the access port 13 in this direction, avoiding the risk of interference between the pull rod 20 and the dryer bag 40.

[0037] According to one embodiment of this application, the dryer suitcase also includes a cover 14, which is detachably disposed over the access port 13.

[0038] This embodiment also includes an openable cover 14 on the access port 13. When the drying bag 40 is stored in the functional cavity 12 and the drying function is not used, the cover 14 can close the access port 13. On the one hand, this prevents the blower module 30 and the drying bag 40 in the functional cavity 12 from sliding out or falling off from the access port 13 due to bumps or tilting during the transportation and handling of the suitcase. On the other hand, it keeps the appearance of the side of the suitcase 10 near the pull rod 20 flat and intact, avoiding the access port 13 being exposed and affecting the overall appearance of the suitcase, and also preventing the protruding structure from being scratched and damaged during use.

[0039] According to one embodiment of this application, the cover plate 14 includes a first edge 141 and a second edge 142. The cover plate 14 is hinged to the box body 10 via the first edge 141, and the second edge 142 is detachably connected to the box body 10 via a zipper 15, a buckle, or a magnetic component.

[0040] The cover 14 is hinged to the housing 10 via the first edge 141, ensuring that the cover 14 remains connected to the housing 10 during opening and closing, preventing it from detaching and being lost during use. The second edge 142 is detachably connected to the housing 10 via a zipper 15, a buckle, or a magnetic attachment, allowing the cover 14 to be securely locked onto the access opening 13 when closed, preventing accidental opening during transport. Simultaneously, it allows for quick disengagement and opening of the cover 14 when the dryer bag 40 needs to be accessed, balancing sealing reliability with ease of operation.

[0041] According to one embodiment of this application, the blower module 30 is disposed in the functional cavity 12 at one end away from the take-up and put-down port 13, and the air outlet 31 is disposed facing the take-up and put-down port 13.

[0042] The blower module 30 is positioned inside the functional cavity 12 at the end furthest from the take-up and put-out port 13, so that the blower module 30 is located deep at the bottom of the functional cavity 12. The folded clothes drying bag 40 is naturally stacked between the blower module 30 and the take-up and put-out port 13, and is not obstructed by the blower module 30 when taking out or putting in the clothes drying bag 40. At the same time, the air outlet 31 is oriented towards the take-up and put-out port 13, so that after the clothes drying bag 40 is pulled out and unfolded from the take-up and put-out port 13, its air inlet 41 is exactly aligned with the air outlet 31. The airflow can flow smoothly from one end of the air inlet 41 to the far end along the longitudinal direction of the clothes drying bag 40. An effective air delivery path can be formed without additional adjustment of the orientation or position of the clothes drying bag 40, simplifying the operation and improving the air delivery efficiency.

[0043] According to one embodiment of this application, the blower module 30 includes a stretchable power cord 32, which is housed within the functional cavity 12.

[0044] The blower module 30 is equipped with a retractable power cord 32 and is stored in the functional cavity 12. When in use, the power cord is pulled out to the required length and connected to an external power source to power the blower module 30. After use, the power cord is retracted and stored in the functional cavity 12 to prevent the power cord from being exposed, tangled or occupying the storage cavity 11 space, keeping the inside of the cabinet 10 neat and orderly, and also avoiding the risk of the power cord being pulled, worn or lost during transportation.

[0045] In this embodiment, the stretchable power cord 32 refers to a power cord structure that can freely switch between being pulled out and retracted. For example, the stretchable power cord 32 can be a spring cord, meaning the power cord body is coiled in a spiral spring shape. When stretched, the spring cord extends axially to provide the required length, and after being released, it automatically retracts back to its initial coiled state under its own elastic restoring force. Alternatively, the stretchable power cord 32 can be a cable housed in a reel, with a spring mechanism inside the reel enabling both pulling out and automatic rewinding. Both methods allow the power cord to be pulled out to the required length during use and automatically retracted into the functional cavity 12 after use, preventing the cable from being exposed and tangled.

[0046] According to one embodiment of this application, the clothes drying suitcase also includes a rechargeable battery, which is disposed within the functional cavity 12 and electrically connected to the blower module 30 to power the blower module 30. With the built-in rechargeable battery, the blower module 30 does not require an external power source during operation. Users can still use the drying function normally in environments without mains power outlets or where wiring is inconvenient, further enhancing the flexibility and portability of the clothes drying suitcase in different travel scenarios. Once fully charged by an external power source before or during the trip, the rechargeable battery can independently and continuously power the blower module 30, meeting the power needs for single or multiple clothes drying cycles.

[0047] According to one embodiment of this application, the clothes drying bag 40 is provided with a hook 42, and a hook hole is provided at the end of the clothes drying bag 40 away from the air inlet 41. The hook hole is used for the hook 42 to pass through and be hung on the pull rod 20 in the pulled-out state.

[0048] The clothes drying bag 40 is equipped with a hook 42, and a hook hole is opened at the end of the clothes drying bag 40 away from the air inlet 41. After the hook 42 passes through the hook hole, it is hung on the pull rod 20 in the pulled-out state. Thus, the top of the clothes drying bag 40 is suspended and fixed to the pull rod 20 via the hook 42, and the air inlet 41 at the bottom is connected to the air outlet 31 of the blowing module 30 in the functional cavity 12. The clothes drying bag 40 hangs down and unfolds naturally under its own weight, forming an air supply channel from bottom to top. Clothes suspended inside the bag can receive sufficient airflow. The hook hole is opened at the end away from the air inlet 41, so that the outlet position of the hook 42 and the air inlet 41 are respectively located at the two ends of the clothes drying bag 40, which is conducive to the clothes drying bag 40 fully unfolding longitudinally after being hung, increasing the effective drying space inside the bag.

[0049] In this embodiment, the hanging member 42 can be exemplarily a clothes hanger. The clothes hanger passes through the hanging hole at the end of the drying bag 40 away from the air inlet 41 and is hung on the pull rod 20 in the pulled-out state. By using a clothes hanger as the hanging member 42, the clothes to be dried can be hung on the clothes hanger first, and then the clothes hanger together with the clothes can be placed into the drying bag 40. This allows the clothes to be exposed to the airflow in an unfolded and suspended position inside the drying bag 40, rather than being piled up or huddled at the bottom of the bag. When the clothes are in the unfolded state, the surfaces of all parts of the clothes can be fully exposed to the airflow, which is conducive to the airflow evenly contacting the front, back, sleeves, and other areas of the clothes, thereby improving the uniformity and efficiency of drying and avoiding the situation where local areas are difficult to be effectively touched by the airflow and remain damp due to the folding and overlapping of the clothes. In addition, the clothes hanger can also better unfold the drying bag 40, making the airflow smoother.

[0050] According to one embodiment of this application, the air inlet 41 of the drying bag 40 is provided with an elastic closing part, which is sleeved on the outer periphery of the air outlet 31 of the blower module 30 to receive the airflow output from the air outlet 31.

[0051] The air inlet 41 of the drying bag 40 is equipped with an elastic closing part, which is fitted around the outer periphery of the air outlet 31 of the blower module 30. This allows the air inlet 41 to fit tightly against and wrap around the outer periphery of the air outlet 31, reducing the possibility of airflow leakage from the blower module 30 through the gap between the air inlet 41 and the air outlet 31 when entering the drying bag 40, thus improving the effective utilization rate of airflow and drying efficiency. At the same time, the elasticity of the closing part allows it to adapt to air outlets 31 with different outer diameters, making it convenient to put on and take off, facilitating the quick assembly and storage of the drying bag 40.

[0052] According to one embodiment of this application, the blower module 30 has a mating groove surrounding the outer periphery of the air outlet 31, an elastic closing portion is embedded in the mating groove, and a sealing ring is provided between the elastic closing portion and the mating groove.

[0053] A mating groove is formed around the outer periphery of the air outlet 31 on the blower module 30. The elastic closing part is embedded in the mating groove, and a sealing ring is provided between the elastic closing part and the mating groove. The mating groove provides radial restraint for the elastic closing part, preventing it from slipping or falling off along the outer periphery of the air outlet 31 under airflow pressure, making the connection between the drying bag 40 and the blower module 30 more stable and reliable. The sealing ring fills the mating gap between the elastic closing part and the mating groove, further eliminating airflow leakage channels at this connection, allowing the airflow output from the air outlet 31 to be more completely introduced into the drying bag 40, maintaining stable sealing performance and air delivery efficiency during long-term continuous drying.

[0054] According to one embodiment of this application, the blower module 30 further includes a heating unit for heating the airflow output from the air outlet 31.

[0055] The blower module 30 also includes a heating unit, which heats the airflow output from the air outlet 31, causing the airflow inside the drying bag 40 to change from room temperature airflow to hot airflow, thereby accelerating the evaporation rate of moisture on the surface of the clothes and inside the fibers, and shortening the drying time of the clothes. It is especially suitable for use scenarios where there is limited time to stay during travel and clothes need to be dried quickly.

[0056] It should be understood that the heating power of the heating unit in this embodiment can be adaptively set according to actual drying needs and safety requirements. In the case of luggage, the power of the heating unit should be set within a reasonable range while meeting the drying efficiency requirements, so that the temperature of the hot air output from the air outlet 31 is within a range suitable for drying clothes without causing heat damage to the material of the drying bag 40, the structure of the box 10, and surrounding items. In addition, over-temperature protection components such as thermal switches can be installed in the power supply circuit of the heating unit. When the temperature inside the functional cavity 12 or at the air outlet 31 exceeds a preset safety threshold, the power supply to the heating unit is automatically cut off to further ensure safety. Through the combination of the above power settings and safety protection measures, the heating unit can operate safely and reliably in the specific usage environment of a luggage suitcase.

[0057] According to one embodiment of this application, the blowing module 30 includes a centrifugal fan. The airflow is accelerated by the impeller and discharged radially. Compared with an axial fan, the centrifugal fan has a flatter overall structure, which facilitates its arrangement and installation within the limited space of the functional cavity 12 and is beneficial to the rational utilization of the internal space of the housing 10.

[0058] According to one embodiment of this application, a heat insulation plate and / or a waterproof plate are provided between the storage cavity 11 and the functional cavity 12.

[0059] In this embodiment, the heat insulation plate can prevent the heat generated by the blower module 30 during operation from being conducted to the storage cavity 11, thus preventing the high-temperature airflow in the functional cavity 12 from affecting the clothes and other items stored in the storage cavity 11; the waterproof plate can prevent the moisture generated by the evaporation of clothes during the drying process from seeping into the storage cavity 11, thus preventing the dried clothes in the storage cavity 11 from getting damp. The two are designed together to achieve a dual protection effect of heat insulation and moisture prevention, preventing the operation of the drying function from adversely affecting the items in the storage cavity 11.

[0060] According to one embodiment of this application, the clothes drying bag 40 is provided with a plurality of dehumidification holes, and the density of the dehumidification holes gradually increases in the direction away from the air inlet 41.

[0061] The drying bag 40 has multiple venting holes, with the density of the vents gradually increasing away from the air inlet 41. After entering the drying bag 40 through the air inlet 41, the airflow flows longitudinally along the bag body. The air pressure is higher and the flow rate is faster near the air inlet 41, while the air pressure gradually decreases away from the air inlet 41. By gradually increasing the density of the venting holes away from the air inlet 41, the airflow is forced to continue flowing further away from the air inlet 41 because there are fewer venting holes near the air inlet 41. The more venting holes at the far end facilitate the airflow to fully blow away the clothes at the far end before being discharged, thus making the airflow distribution in all areas inside the bag body more balanced and improving the overall drying uniformity.

[0062] According to one embodiment of this application, the clothes drying bag 40 is provided with a restraint for maintaining its folded state. The restraint is a strap, elastic band, snap, buckle, or Velcro. After the clothes drying bag 40 is folded and stored in the functional cavity 12, the restraint tightens and secures the folded clothes drying bag 40, preventing it from unraveling due to bumps during luggage transportation, keeping the interior of the functional cavity 12 neat and orderly, and also facilitating quick release and unfolding of the clothes drying bag 40 for the next use.

[0063] According to one embodiment of this application, the clothes drying bag 40 includes an air guide 44 and a drying section 43. In the unfolded state, the drying section 43 of the clothes drying bag 40 is hung on the pull rod 20 in the pulled-out state. One end of the air guide 44 serves as an air inlet 41 and is connected to the blower module 30. The other end of the air guide 44 is connected to the middle of the drying section 43.

[0064] In this embodiment, the air guide section 44 serves as an airflow channel connecting the blower module 30 and the drying section 43. It guides the airflow output from the blower module 30 along the air guide section 44 to the middle of the drying section 43 before sending it into the inner cavity of the drying section 43. Since the airflow is introduced through the air guide section 44, the size of the drying section 43 is not limited by its connection to the blower module 30 and the pull rod 20 at both ends, allowing for a larger size design and the ability to accommodate and unfold larger garments. Correspondingly, the air guide section 44 no longer needs to accommodate garments, and its cross-sectional dimensions can be much smaller than the drying section 43, occupying less space when folded and stored. The separate structure of the two sections allows the drying bag 40 to have ample drying space while also being easily folded and compactly stored within the functional cavity 12.
