[0032] To make the above-mentioned objects, features and advantages of the present invention more apparent and understandable, the specific embodiments of the present invention will be described in detail below with reference to the accompanying drawings.

[0033] Secondly, the present invention is described in detail with reference to the schematic diagrams. When detailing the embodiments of the present invention, for ease of explanation, the cross-sectional views illustrating the device structure may be partially enlarged, not according to the usual scale. Furthermore, the schematic diagrams are merely examples and should not limit the scope of protection of the present invention. In addition, actual fabrication should include three-dimensional spatial dimensions of length, width, and depth.

[0034] To make the objectives, technical solutions, and advantages of the present invention clearer, the embodiments of the present invention will be described in further detail below with reference to the accompanying drawings.

[0035] This invention provides a portable sports backpack for drying and sterilizing clothes. It can dry the clothes stored inside the backpack during hiking, keeping the clothes dry. It can also dry clothes in batches, drying another batch of clothes at intervals to prevent damage to clothes caused by prolonged high-temperature drying.

[0036] Example 1

[0037] Figures 1-4 show a schematic diagram of the structure of a portable sports backpack for drying and sterilizing clothes according to the first embodiment of the present invention. Referring to Figures 1-4, the portable sports backpack for drying and sterilizing clothes according to this embodiment includes a backpack 100, a clothing storage bag 200, a drive assembly 300, a drying assembly 400, and an air compression assembly 500.

[0038] Backpack 100 includes a storage layer 110, a drying layer 120 installed at the bottom of the storage layer 110, and a drive layer 130 installed at the bottom of the drying layer 120. The storage layer 110 has a shoulder strap 140 installed on its side wall, and the drive layer 130 has a ventilation slot 130a on its side wall. The top opening of the storage layer 110 is connected to a cover, and the cover is closed to the top of the storage layer 110 by a zipper. The shoulder strap 140 is used to carry the backpack 100 on the back. Not shown in the figure, the storage layer 110 may be made of leather.

[0039] The clothing storage bag 200 is located inside the storage layer 110. A base plate 210 is installed at the bottom of the clothing storage bag 200. A partition 220 is installed inside the clothing storage bag 200, which divides the interior of the clothing storage bag 200 into four independent chambers. Each chamber is equipped with a drying cylinder 230. The outer wall of the drying cylinder 230 has air holes 230a. The bottom of the base plate 210 has a second opening 210a at a position corresponding to the drying cylinder 230. When storing clothes, the clothes can be placed into the four chambers and surrounded by the drying cylinder 230. When hot air enters the drying cylinder 230 through the second opening 210a, the hot air is discharged through the air holes 230a densely distributed on the outer wall of the drying cylinder 230, and dries the clothes surrounding the drying cylinder 230. Not shown in the figure, the clothing storage bag 200 and the partition 220 can be made of nylon or polyester.

[0040] The drive assembly 300 includes a winding roller 310 rotatably connected to the side wall of the drive layer 130 and a strap 320 located below the drive layer 130. A torsion spring is connected between the winding roller 310 and the drive layer 130. A steel wire rope is wound around the outer wall of the winding roller 310. The other end of the steel wire rope is connected to the strap 320. When drying is required, the strap 320 can be tied to the leg. With each step forward during hiking, the strap 320 is driven forward and the steel wire rope pulls the winding roller 310 to rotate and compress the torsion spring. When the leg moves backward, the torsion spring rebounds and drives the winding roller 310 to reverse, rewinding the steel wire rope onto the surface of the winding roller 310.

[0041] The drying assembly 400 includes a fixed cylinder 410 installed inside the drying layer 120 and communicating with the second opening 210a, and a gas heating assembly 420 installed inside the drying layer 120 and connected to the fixed cylinder 410. A fan blade 410b is rotatably connected inside the fixed cylinder 410. The fan blade 410b is connected to the winding roller 310 and the garment storage bag 200. After the fan blade 410b rotates for a fixed time, it drives the garment storage bag 200 to rotate. Each time the winding roller 310 rotates, it drives the fan blade 410b to rotate. When the gas heating assembly 420 rubs the compressed air to form hot air, the hot air is input into the connecting pipe 410a and blown by the rotating fan blade 410b to form an upward airflow, which enters the drying cylinder 230 through the second opening 210a.

[0042] An air compression assembly 500 is installed inside the drive layer 130 and connected to the winding roller 310. The other end of the air compression assembly 500 is connected to the air heating assembly 420. When the winding roller 310 rotates, the winding roller 310 drives the air compression assembly 500 to compress the air and deliver it to the air heating assembly 420.

[0043] Referring to Figures 1-4, this embodiment of a portable sports backpack for drying and sterilizing clothes involves tying straps 320 to the legs when drying clothes inside the storage bag 200. As the legs move forward during hiking, the straps 320 move forward, pulling the winding roller 310 via a steel wire rope. This rotation causes the fan blades 410b to rotate, which in turn drives the air compression assembly 500 to deliver compressed air to the air heating assembly 420. The air heating assembly 420 converts the compressed air into hot air and delivers it to the fixed cylinder 410. As the fan blades 410b rotate, the hot air is fed into the drying cylinder 230 and discharged through the air holes 230a, drying the clothes in the two symmetrical cavities inside the storage bag 200. After the legs move forward a certain number of times, i.e., after the fan blades 410b rotate a certain number of times, the fan blades 410b drive the storage bag 200 to rotate. The other two symmetrical second openings 210a are connected to the fixed cylinder 410, drying the clothes in the other two cavities.

[0044] Example 2

[0045] Figures 1-8 show schematic diagrams of a second embodiment of the portable sports backpack for drying and sterilizing clothes according to the present invention. Referring to Figures 1-8, unlike the above embodiments, this embodiment of the portable sports backpack for drying and sterilizing clothes further includes:

[0046] The gas heating assembly 420 includes a gas chamber 420a, a delivery pipe 420b installed at one end of the gas chamber 420a, and a cold air outlet pipe 420c installed at the other end of the gas chamber 420a. An air inlet 420a-1 is provided at the top of the gas chamber 420a, and the air inlet 420a-1 vertically penetrates downwards into the interior of the gas chamber 420a to form an oblique through hole. A first sealing plate 420b-1 is installed on the side end of the delivery pipe 420b, and a second sealing plate 420c-1 is installed on the side end of the cold air outlet pipe 420c. A connecting pipe 410a is installed on the side wall of the fixed cylinder 410, communicating with the interior of the fixed cylinder 410. A baffle 420b-2 is installed at the opening at the other end of the delivery pipe 420b, and a ring of micro-perforations 420b-3 is formed on the side wall of the baffle 420b-2. A conical protrusion 420b-2 is installed on one side wall inside the conveying pipe 420b. One end of the conveying pipe 420b with the baffle 420b-2 extends into the connecting pipe 410a. A rotating rod 310a is installed on the side wall of the winding roller 310. The other end of the rotating rod 310a extends into the drive layer 130 and is equipped with a fifth helical gear 310b. A threaded rod 310c is installed on the side wall of the fifth helical gear 310b. A sixth helical gear 410b-1 is rotatably connected to the bottom of the drying layer 120. The sixth helical gear 410b-1 is coaxially fixedly connected to the fixed cylinder 410. The sixth helical gear 410b-1 meshes with the fifth helical gear 310b. When the strap 320 moves forward and drives the winding roller 310 to rotate, the winding roller 310 drives the rotating rod 310a to rotate. 10a and the fifth helical gear 310b rotate. The fifth helical gear 310b drives the sixth helical gear 410b-1 and the fan blade 410b to rotate. When compressed air enters the air chamber 420a through the air inlet 420a-1, the hole formed by the vertical downward air inlet 420a-1 and the inner wall of the air chamber 420a has a certain angle. After entering the air chamber 420a, the compressed air rotates at high speed along the delivery pipe 420b and inside the air chamber 420a. Not shown in the figure, to accelerate the rotation of the compressed air inside the air chamber 420a and the delivery pipe 420b, a nozzle with an angled hole can be installed inside the air chamber 420a. When the compressed air rotates inside the air chamber 420a and the delivery pipe 420b, the nozzle closest to the inner wall of the delivery pipe 420b... The airflow rotates at a lower angular velocity, while the airflow near the center of the delivery pipe 420b rotates at a higher angular velocity. Due to the difference in angular velocity, friction occurs between the inner and outer airflows. The internal energy of the gas in the inner vortex is continuously converted into rotational kinetic energy. As the internal energy of the gas in the inner vortex decreases, the temperature of the inner vortex decreases. The outer airflow continuously gains kinetic energy due to friction to maintain rotation, and at the same time, the internal energy of the gas continuously increases, leading to a rise in temperature. When the vortex reaches the port of the delivery pipe 420b, i.e., at the position of the baffle 420b-2, the hot airflow in the outer ring escapes through the micro-hole 420b-3 into the interior of the connecting pipe 410a and is transported to the interior of the fixed cylinder 410. Meanwhile, the cold airflow in the inner ring is blocked inside the delivery pipe 420b by the conical protrusion 420b-4. As the cold airflow is blocked, the pressure increases.Then, the hot air flows out in the opposite direction along the cold air outlet pipe 420c. When the hot air enters the fixed cylinder 410, the rotating fan blades 410b push the hot air through the second opening 210a into the drying cylinder 230.

[0047] The air compression assembly 500 includes a compression tube 510 installed inside the drive layer 130, a piston 520 located inside the compression tube 510, a first hose 530 installed on the side wall of the compression tube 510 and connected to the air heating assembly 420, and a second hose 540 installed on the side wall of the compression tube 510. A fixing rod 520a is installed on the side wall of the piston 520, and a threaded hole 520a-1 is opened at the side end of the fixing rod 520a. The threaded rod 310c rotates and extends into the threaded hole 520a-1. A first one-way valve 530a is installed on the body of the first hose 530, and a second one-way valve 540a is installed on the body of the second hose 540. When the winding roller 310 rotates, it drives the rotating rod 310a and the threaded rod 310c to rotate. The threaded rod 310c pushes the fixing rod 520a and the piston 520 towards the compression tube 510. When the piston moves into the compression tube 510, the first one-way valve 530a opens and the second one-way valve 540a closes. The air inside the compression tube 510 is compressed by the piston 520 and enters the air inlet 420a-1 through the first hose 530. Not shown in the figure, there is a spring between the side wall of the piston 520 and the inner wall of the compression tube 510. When the piston 520 moves into the compression tube 510, it compresses the spring. When the torsion spring drives the winding roller 310 to reverse, the rotating rod 310a and the threaded rod 310c reverse. The screw structure pulls the fixed rod 520a and the piston 520 to move out of the compression tube 510. At the same time, the spring pushes the piston 520 to move out of the compression tube 510. At this time, 531 closes and 541 opens. The air inside the drive layer 130 enters the compression tube 510 through the second hose 540.

[0048] A second gear 240 is mounted on the bottom of the chassis 210, located at the center of the bottom of the chassis 210. The second gear 240 is rotatably connected to the bottom of the storage layer 110. An opening 110a is provided at the bottom of the storage layer 110, communicating with the fixed cylinder 410.

A second helical gear 110d-2 is installed on the side wall of the first one-way gear 110d-1, and the second helical gear 110d-2 meshes with the first helical gear 110c-1. A third pulley 410b-2 is installed at the bottom of fixed cylinder 410. A second one-way gear 120a is rotatably connected to the bottom of drying layer 120. The second one-way gear 120a and the third pulley 410b-2 are connected by a belt. A third one-way gear 120a-1 is rotatably connected to the bottom of drying layer 120. The third one-way gear 120a-1 meshes with the second one-way gear 110c-1. One-way gear 120a meshes, and a third helical gear 120a-2 is installed on the top of the third one-way gear 120a-1. Two second fixed plates 120b are symmetrically installed on the inner wall of the drying layer 120. A reciprocating threaded rod 120b-1 is installed between the two second fixed plates 120b. A fourth helical gear 120b-2 is installed on the body of the reciprocating threaded rod 120b-1. The fourth helical gear 120b-2 meshes with the third helical gear 120a-2. A one-way rack 120c is slidably connected inside the drying layer 120. A reciprocating threaded hole 120c-1 is opened on the side wall of the one-way rack 120c. The reciprocating threaded rod 120b-1 rotates through the reciprocating threaded hole 120c-1. When the winding roller 310 rotates and drives the fan blade 410b to rotate, the fan blade 410b rotates. 10b drives the third pulley 410b-2 to rotate. The third pulley 410b-2 drives the second one-way gear 120a to rotate via a belt. The second one-way gear 120a drives the third one-way gear 120a-1 and the third helical gear 120a-2 to rotate. The rotation of the third helical gear 120a-2 drives the fourth helical gear 120b-2 and the reciprocating threaded rod 120b-1 to rotate, pushing the one-way rack 120c to move a certain distance along the reciprocating threaded rod 120b-1 until the one-way rack 120c meshes with the first one-way gear 110d-1. As the fan blade 410b rotates, it drives the one-way rack 120c to move. When the one-way rack 120c moves, it drives the first one-way gear 110d-1 and the second helical gear 110d-2 to rotate.The second helical gear 110d-2 drives the first helical gear 110c-1 and the second pulley 110c to rotate. The second pulley 110c, via a belt, drives the first pulley 110b-1 and the first gear 110b to rotate. The first gear 110b drives the second gear 240 to rotate, causing the storage bag 200 to rotate 90°. The other two second openings 210a are connected to the opening 110a, awaiting drying.

[0049] Referring to Figures 1-8, in this embodiment of a portable sports backpack for drying and sterilizing clothes, during hiking, the legs move the straps 320 forward and rotate the winding roller 310. The rotation of the winding roller 310 drives the fifth helical gear 310b and the threaded rod 310c to rotate. The fifth helical gear 310b drives the fan blade 410b to rotate, and the rotation of the threaded rod 310c pushes the piston 520 to move into the compression tube 510, compressing and delivering the air inside the compression tube 510 to the air chamber 420a. The air rotates along the inside of the delivery tube 420b until it reaches the baffle 420b-2 position, and then enters the connecting tube 410a and the fixing cylinder 410 through the micropores 420b-3. When the fan blade 410b rotates... Hot air is sent into the drying cylinder 230 and discharged through the air hole 230a. When the fan blade 410b rotates, it drives the reciprocating threaded rod 120b-1 to rotate, which in turn drives the one-way rack 120c to move a certain distance until the one-way rack 120c meshes with the first one-way gear 110d-1. As the fan blade 410b rotates, it drives the one-way rack 120c to move. When the one-way rack 120c moves, it drives the first one-way gear 110d-1 and the second helical gear 110d-2 to rotate, which in turn drives the first gear 110b to rotate. The first gear 110b drives the second gear 240 and the garment storage bag 200 to rotate 90°. The other two second openings 210a are connected to the opening 110a and are waiting for subsequent drying.
