[0037] As Figures 1 to 11 shown, a portable air-conditioning backpack includes a bag body 1. A cooling mechanism 2 is provided on the lower side inside the bag body 1. A bracket 3 is provided inside the bag body 1, and items can be placed on the bracket 3. An accessory bag 4 is provided on the front side of the bag body 1, and items can be stored in the accessory bag 4. Shoulder straps 5 are provided on the upper part of the rear side of the bag body 1. A shielding assembly is provided on the upper part of the bracket 3. An injection assembly is provided on the side of the shielding assembly. A buffer assembly is provided on the lower part of the rear side of the bag body 1. The bracket 3 is provided above the cooling mechanism 2. A cavity is provided between the bracket 3 and the inner wall of the rear side of the backpack. The shielding assembly and the injection assembly are used in cooperation. The buffer assembly is provided at the connection between the shoulder straps 5 and the bag body 1;

[0038] When the cooling mechanism 2 operates, it can deliver cold air to the wearer. Before use, unfolding the shielding assembly can shield the user and the bag body 1, improving the cooling effect of the cooling mechanism 2. At the same time, the injection assembly can inject helium gas into the shielding assembly, achieving the effect of reducing the weight of the backpack. The buffer assembly can play a role in buffering and massaging during use. Using the shoulder straps 5 to carry the bag body 1 on the user's back demonstrates the convenience of the air-conditioning backpack. The specific connection method and working principle of the backpack and the cooling mechanism 2 are well-known prior art to those skilled in the art and will not be elaborated here.

[0039] As Figure 2 and Figure 3 shown, the cooling mechanism 2 includes a compressor 201 provided on the inner wall of the bottom of the bag body 1. A radiator 202 is provided above the compressor 201. A fan 203 is provided on the side of the compressor 201. The fan 203 communicates with the cavity. A battery pack 204 is provided at the side end of the compressor 201. Ventilation openings are provided on the left and right sides and the rear side of the bag body 1. The ventilation openings on the left and right sides are for facilitating air to enter the bag body 1, and the ventilation opening on the rear side is for discharging cold air;

[0040] By using the compressor 201 and radiator 202 in combination, rapid cooling can be achieved. The bracket 3 provided in the bag body 1 divides the backpack into a cavity. The cold air cooled by the compressor 201 is evenly distributed into the cavity inside the backpack by the fan 203. Subsequently, this cold air slowly flows out through the carefully designed ventilation openings and directly acts on the user's back, thus effectively maintaining the comfortable temperature of the wearer's body. The backpack is equipped with a high-performance battery pack 204, which can support continuous use for six to eight hours, fully meeting the needs of long-term outdoor work. The overall design of the backpack conforms to the ergonomic principle, without a sense of oppression when worn, effectively sharing the weight of the air-conditioning module and reducing the fatigue of long-term wear.

[0041] As Figures 4 to 9 shown, the shielding assembly includes a hollow cylinder 601 fixedly connected to the middle of the bracket 3. The bottom inner wall of the hollow cylinder 601 is provided with a motor 602. The driving end of the motor 602 is fixedly connected with a worm 603. A base 604 is slidably connected inside the hollow cylinder 601. A clamping block is provided on the side of the base 604. A clamping groove is provided in the upper part of the hollow cylinder 601. When the base 604 rises to the position of the clamping groove, it will be clamped and fixed. An inner cylinder 605 is fixedly connected to the upper part of the base 604. A skeleton 606 is hinged to the top of the inner cylinder 605. An airbag 607 is provided on the side of the skeleton 606. The skeleton 606 and the airbag 607 are staggered. A winding shaft 608 is rotatably connected to the lower part of the inner wall of the inner cylinder 605. A worm gear 609 is fixedly sleeved in the middle of the winding shaft 608. The worm gear 609 is meshed with the worm 603. A push rod 611 is hinged to the inner side of the skeleton 606. A limiting slider 613 is fixedly connected to the side of the end of the push rod 611 away from the skeleton 606. A wire rope 610 is wound on the outer surface of the winding shaft 608. One end of the wire rope 610 away from the winding shaft 608 is wound on the outer surface of the limiting slider 613. A track 612 is fixedly connected to the inner wall of the inner cylinder 605. The end of the limiting slider 613 is movably connected inside the track 612. A fixed pulley 614 is provided at the top of the track 612. The wire rope 610 passes around the upper part of the fixed pulley 614;

[0042] First, pull the inner cylinder 605 upward. This action causes the base 604 to slide smoothly along the inner wall of the hollow cylinder 601. When the base 604 slides to the preset card slot position, it will be firmly clamped and fixed. At this time, the worm gear 609 and the worm 603 are exactly in the meshing state. Then, start the motor 602 to drive the worm 603 to rotate, which drives the worm gear 609 to rotate. During the rotation of the worm gear 609, it will drive the winding shaft 608 to rotate. During the rotation of the worm gear 609, it will link the winding shaft 608 to start the winding work of the wire rope 610. At the other end of the wire rope 610, through the precise positioning of the fixed pulley 614, the limiting sliding member 613 is pulled to slowly rise along the track 612. The upward movement of the limiting sliding member 613 drives the push rod 611 to move along the track 612. Since one end of the push rod 611 is designed to only slide up and down, the other end of the push rod 611 will flip outward accordingly, and then drive the frame 606 to rotate outward around the end of the inner cylinder 605. The flipping of the frame 606 will pull the airbag 607 to unfold. The umbrella-shaped structure formed by the frame 606 and the airbag 607 can effectively block the sunlight and prevent the backpack and the user from being directly irradiated by the sun, thus significantly improving the cooling effect of the cooling mechanism 2.

[0043] As Figure 2 , Figure 4 and Figure 10 shown, the injection assembly includes a helium cylinder 701 fixedly connected to the side of the hollow cylinder 601. The lower surface of the bracket 3 is rotatably connected with a combined rod 703. The combined rod 703 is composed of a round rod and a threaded rod. An active wheel 702 is fixedly sleeved on the outer surface of the worm 603. A driven wheel 704 is fixedly sleeved on the outer surface of the part of the combined rod 703 extending out of the helium cylinder 701. The active wheel 702 is meshed and connected with the driven wheel 704. A piston 705 is threadedly connected to the outer surface of the part of the combined rod 703 extending into the helium cylinder 701. The piston 705 is limited to slide inside the helium cylinder 701. A gas guide pipe 706 is arranged at the top of the helium cylinder 701. One end of the gas guide pipe 706 far from the helium cylinder 701 is fixedly connected to the valve port of the airbag 607. The airbag 607 is elastic and the rest of the parts are sealed. Only the valve port is connected to the gas guide pipe 706. The amount of nitrogen stored in the helium cylinder 701 is greater than the capacity of the airbag 607;

[0044] While the worm 603 is rotating, it will drive the active wheel 702 to rotate. Through the transmission of the driven wheel 704, the rotation of the combined rod 703 is further driven, and then the piston 705 is driven to move upward inside the helium cylinder 701. With the extrusion of the piston 705, the helium gas in the helium cylinder 701 is smoothly extruded out and flows into the airbag 607 through the gas guide pipe 706, so that the airbag 607 is quickly filled with helium gas. Since the density of helium gas is lower than that of air, the airbag 607 filled with helium gas has a certain buoyancy, achieving the effect of reducing the weight of the backpack and improving the user experience.

[0045] As Figure 3 and Figure 11 shown, the buffer assembly includes a frame plate 801 fixedly connected to the outer surface of the bag body 1. A slider 802 is movably inserted through one side of the frame plate 801 away from the bag body 1. The slider 802 has a convex-shaped structure. One end of the slider 802 extending out of the frame plate 801 is fixedly connected to the shoulder strap 5. One end of the slider 802 extending into the frame plate 801 is fixedly connected to a spring 803. The end of the spring 803 away from the slider 802 is fixedly connected to the inner wall of the frame plate 801. A central rod 804 is rotatably connected to the middle of the frame plate 801. A gear 805 is fixedly sleeved on the outer surface of the central rod 804 located inside the frame plate 801. A rack 806 is arranged inside the slider 802. The rack 806 is meshed with the gear 805. A massage rod 807 is fixedly sleeved on the outer surface of the central rod 804 located outside the frame plate 801;

[0046] During the process of the bag body 1 approaching or moving away from the user's back, the slider 802 will be driven to slide inside the frame plate 801, so that the slider 802 compresses or stretches the spring 803. The spring 803 is used to buffer the impact force on the back, achieving a certain buffering effect. At the same time, the movement of the slider 802 will drive the rack 806 to move and drive the gear 805 to rotate. During the rotation of the gear 805, the central rod 804 will be driven to rotate. The central rod 804 drives the massage rod 807 to rotate. The massage rod 807 is placed at the user's waist position and can perform appropriate rolling massage on the user's waist, which helps to relieve the user's fatigue.

[0047] For the technical solution provided by the present invention, when using the air-conditioned backpack, first pull the inner cylinder 605 upward, so that the base 604 slides along the inner wall of the hollow cylinder 601. When the base 604 slides to the card slot, it will be clamped and fixed. At this time, the worm gear 609 meshes with the worm 603. Start the motor 602, and the motor 602 drives the worm 603 to rotate, thereby driving the worm gear 609 to rotate. During the rotation of the worm gear 609, the winding shaft 608 will be driven to rotate, and then the wire rope 610 will be wound. Under the positioning of the fixed pulley 614, the other end of the wire rope 610 will pull the limit sliding member 613 to rise. The limit sliding member 613 slides upward along the track 612 and drives the push rod 611 to move along the track 612. Since this end of the push rod 611 can only slide up and down, the other end of the push rod 611 will be driven to turn outward, and then the framework 606 will be driven to rotate outward around the end of the inner cylinder 605. The flipping of the framework 606 will pull the airbag 607 to unfold. The umbrella-shaped structure composed of the framework 606 and the airbag 607 can block the sun, thereby avoiding the backpack and the user from being directly exposed to the sun and improving the cooling effect of the cooling mechanism 2. While the worm 603 is rotating, it will drive the driving wheel 702 to rotate. Through the transmission of the driven wheel 704, the combined rod 703 is further driven to rotate, and then the piston 705 is driven to move upward in the helium cylinder 701. With the extrusion of the piston 705, the helium in the helium cylinder 701 is smoothly extruded and flows into the airbag 607 through the air guide pipe 706, so that the airbag 607 is quickly filled with helium. Since the density of helium is lower than that of air, the helium-filled airbag 607 has a certain buoyancy, achieving the effect of reducing the weight of the backpack and improving the user experience;

[0048] Then the user carries the bag body 1 on the back using the shoulder strap 5. The combined use of the compressor 201 and the radiator 202 can quickly cool down. The bracket 3 divides the backpack into a cavity. The cold air is evenly distributed into the cavity inside the backpack through the fan 203 and then flows out to the user's back through the ventilation openings. The cold air maintains a comfortable temperature for the wearer's body. The high-efficiency battery pack 204 can support continuous use for six to eight hours, meeting the needs of long-term outdoor work. The backpack is designed ergonomically, without a sense of compression when worn, and effectively shares the weight of the air-conditioning module, reducing the fatigue of long-term wearing. During the user's work process, due to movement, the backpack will frequently collide with the user's back. When the bag body 1 approaches or moves away from the user's back, it will drive the slider 802 to slide inside the frame plate 801, causing the slider 802 to compress or stretch the spring 803. The spring 803 is used to buffer the impact force on the back, achieving a certain buffering effect. At the same time, the movement of the slider 802 will drive the rack 806 to move and drive the gear 805 to rotate. During the rotation of the gear 805, the central rod 804 is driven to rotate, and the central rod 804 drives the massage rod 807 to rotate. The massage rod 807 is placed at the user's waist position and can perform appropriate rolling massage on the user's waist, helping to relieve the user's fatigue. After use, start the motor 602 to rotate in the reverse direction to draw the helium gas into the helium cylinder 701. At the same time, the skeleton 606 will fall and fit on the outer surface of the inner cylinder 605, and press down to draw the inner cylinder 605 into the hollow cylinder 601, facilitating the storage of the backpack.
