The liquid storage assembly 20 is placed inside the first sub-cavity 10b, and the atomization module 40 is placed inside the second sub-cavity 10c; the second end of the first pipe section 31 passes through the first through-hole 12a from a side of the first sub-cavity 10b into the second sub-cavity 10c and is communicated with the liquid inlet end of the liquid inlet connector 41, and the second end of the second pipe section 32 passes through the second through-hole 12b from a side of the second sub-cavity 10c into the first sub-cavity 10b and passes through the first pipeline outlet 10d to partially extend out of the first sub-cavity 10b.

(45) The partition layer 12 can be detachably connected to the bag body 11 through methods such as, but not limited to, buckle fastening, or can be non-detachably connected to the bag body 11 through methods such as, but not limited to, thread stitching.

(46) The partition layer 12 is used to divide the storage cavity 10a of the bag body 11 into two mutually independent first sub-cavity 10b and second sub-cavity 10c. By placing the liquid storage assembly 20 in the first sub-cavity 10b, which is closer to the user's back, when the outdoor sports backpack 1 is in a worn state, the liquid storage assembly 20 placed in the first sub-cavity 10b can be in contact with the user's back, providing a certain cooling effect to the user's back. Moreover, since the liquid storage assembly 20 is entirely made of soft materials, it can enhance comfort of the user when wearing the outdoor sports backpack 1. The partition layer 12 is further configured to divide the storage cavity 10a of the bag body 11 into a first sub-cavity 10b and a second sub-cavity 10c independent from each other. By placing the atomization module 40 in the second sub-cavity 10c, which is farther from the user's back, it can effectively prevent the heat generated by the atomization module 40 in operation from dissipating to the user's back, and the liquid stored in the liquid storage assembly 20 can provide a certain cooling effect to the atomization module 40. By configuring the first through-hole 12a and the second through-hole 12b on the partition layer 12, the first through-hole 12a is configured to allow the first pipe section 31 to pass through, enabling the second end of the first pipe section 31 to be communicated with the liquid inlet end of the liquid inlet connector 41, and the second through-hole 12b is configured to allow the second pipe section 32 to pass through, enabling the second end of the second pipe section 32 to smoothly pass through the first pipeline outlet 10d and extend out of the first sub-cavity 10b, allowing the user to perform spray cooling operations using the exposed second pipe section 32. The configuring of the first through-hole 12a and the second through-hole 12b ensures that the spray pipeline 30 is neatly arranged inside the bag body 11, reducing or even avoiding the possibility of the spray pipeline 30 bending inside the bag body 11, thereby ensuring the normal flow of liquid in the spray pipeline 30.

(47) As shown in FIGS. 8-9, a top of the liquid storage bag 21 can be opened and closed to form a liquid inlet 21a; the liquid storage assembly 20 further includes a sealing member 23, which can be removably connected to the top of the liquid storage bag 21 to seal the liquid inlet 21a. The liquid inlet 21a refers to the opening on the liquid storage bag 21 through which liquid flows into the liquid storage bag 21. By configuring the sealing member 23 to be removably connected to the top of the liquid storage bag 21, when it is necessary to fill the liquid storage bag 21 with liquid, the user needs to remove the sealing member 23 from the top of the liquid storage bag 21 to open the liquid inlet 21a, allowing external liquid to be promptly replenished into the liquid storage bag 21. After the liquid storage bag 21 is filled with liquid, the user needs to reinstall the sealing member 23 on the top of the liquid storage bag 21 to seal the liquid inlet 21a.

(48) Specifically, the liquid storage bag 21 includes a bag body 211, a squeezing flange 212, a first fixing flange 213, and a second fixing flange 214. The bag body 211 has the liquid outlet 20a and the liquid inlet 21a; the squeezing flange 212 is located at the top of the bag body 211 and is connected to a first side A of the bag body 211. The first fixing flange 213 and the second fixing flange 214 are located at the top of the bag body 211 and are connected to a second side B of the bag body 211, with the first side A and the second side B being opposite sides of the bag body 211. The sealing member 23 includes a sealing sliding buckle 23a, which has a first sliding groove 23b and a second sliding groove 23c arranged opposite to each other. The liquid storage bag 21 has a sealed state, in which the top of the bag body 211 is folded towards the first side A where the squeezing flange 212 is located, so that the first fixing flange 213 and the second fixing flange 214 are arranged opposite to each other, and the first sliding groove 23b engages with the first fixing flange 213, while the second sliding groove 23c engages with the second fixing flange 214.

(49) When the liquid storage bag 21 is in the sealed state, the squeezing flange 212 is used to press and close the top of the bag body 211 to seal the liquid inlet 21a of the bag body 211 on one hand, and, to cooperate with the first fixing flange 213 and the second fixing flange 214 to fix the sealing sliding buckle 23a on the other hand. By configuring the sealing sliding buckle 23a with the first sliding groove 23b and the second sliding groove 23c arranged opposite to each other. When it is necessary to fill the liquid storage bag 21 with liquid, the user needs to slide the sealing sliding buckle 23a to have the sealing buckle 23a to be detached from the top of the liquid storage bag 21, opening the liquid inlet 21a of the liquid storage bag 21 to allow external liquid to be promptly replenished into the liquid storage bag 21. After the liquid storage bag 21 is filled with liquid, the user needs to slide and reinstall the sealing sliding buckle 23a on the top of the liquid storage bag 21, so that the first sliding groove 23b engages with the first fixing flange 213 and the second sliding groove 23c engages with the second fixing flange 214 to seal the liquid inlet 21a of the liquid storage bag 21.

(50) More specifically, the detailed designs of the bag body 211, the squeezing flange 212, the first fixing flange 213, and the second fixing flange 214 may include, but not limited to, one or more of the following situations.

(51) In a first situation, the bag body 211, the squeezing flange 212, the first fixing flange 213, and the second fixing flange 214 are integrally formed. The bag body 211, the squeezing flange 212, the first fixing flange 213, and the second fixing flange 214 may be integrally formed through methods such as, but not limited to, injection molding or 3D printing.

(52) In a second situation, the number of the squeezing flange 212 is one and the squeezing flange 212 is in a strip shape extending along a width direction of the bag body 211. By configuring the squeezing flange 212 in the strip shape extending along the width direction of the bag body 211, comprehensive pressing of the top of the bag body 211 can be achieved, effectively improving the sealing performance of the bag body 211.

(53) In a third situation, the number of the first fixing flanges 213 is plural, and a plurality of first fixing flanges 213 are arranged at intervals along the width direction of the bag body 211, and each first fixing flange 213 is in a strip shape extending along the width direction of the bag body 211. This effectively enhances the connection stability between the first sliding groove 23b of the sealing sliding buckle 23a and the first fixing flanges 213.

(54) In a fourth situation, the number of the second fixing flanges 214 is plural and a plurality of second fixing flanges 214 are arranged at intervals along the width direction of the bag body 211, and each second fixing flange 214 is in a strip shape extending along the width direction of the bag body 211. This effectively enhances the connection stability between the second sliding groove 23c of the sealing sliding buckle 23a and the second fixing flanges 214.

(55) As shown in FIGS. 1-2, the backpack body 10 further includes a breathable storage layer 13, which is connected to a front side of the bag body 11 to form a storage cavity together with the bag body 11 for placing a helmet. Here, the breathable storage layer 13 can be detachably connected to the bag body 11 through methods such as, but not limited to, buckle fastening, or it can be non-detachably connected to the bag body 11 through methods such as, but not limited to, thread stitching. By configuring the breathable storage layer 13, it forms a storage cavity together with the bag body 11, which can be used to store the helmet for convenience of users.

(56) Specifically, the breathable storage layer 13 includes a mesh fabric connected to the bag body 11. The mesh fabric is connected to the bag body 11 through thread stitching, facilitating storage of the helmet by users.

When a user needs to use the spray pipeline 30 for spray cooling operations, the user operates the remote controller 70 to turn on the atomization module 40. Then, the user turns the knob on the spray nozzle to switch it from the closed state to the open state. At this time, the liquid in the liquid storage bag 21 flows out from the interface at the bottom end of the liquid storage bag 21 under the suction force of the atomizer 44, and then passes through the first pipe section 31, the atomizer 44, and the second pipe section 32. Under the action of the atomizer 44, the liquid is atomized into water mist and is ejected from the spray nozzle to achieve a spray cooling effect.

(58) Specifically, the backpack body 10 further includes a left shoulder strap 14 and a right shoulder strap 15 connected to the bag body 11. Both the left shoulder strap 14 and the right shoulder strap 15 are provided with pockets 15a. There are two remote controllers 70, with one placed in the pocket 15a of the left shoulder strap 14 and the other placed in the pocket 15a of the right shoulder strap 15. By configuring the pockets 15a on both the left shoulder strap 14 and the right shoulder strap 15 and configuring two remote controllers 70 for the atomization module 40, it is convenient for users to retrieve and place the remote controllers 70 in the pockets 15a of the left shoulder strap 14 and the right shoulder strap 15 according to actual situations, improving usability convenience.

(59) It should be noted that the left shoulder strap 14 is provided with a fixing member (which can be a fixing ring configured to allow one of the spray pipeline 30 and the drinking pipeline 50 to pass therethrough) configured to fix one of the exposed spray pipeline 30 and the drinking pipeline 50, facilitating positioning of one of the exposed spray pipeline 30 and the drinking pipeline 50 on the left shoulder strap 14.
