[0002] A vacuum compression backpack is a functional backpack that uses vacuum technology to compress the volume of items. It is mainly used in travel and business trips. Its core features are high space utilization, multi-functional integration, and strong portability. Through the built-in air valve and sealed compartment design, users can use the matching vacuum pump or manual air extraction tool to expel air and use atmospheric pressure to compress fluffy items such as clothes and bedding. This can usually reduce the volume by 30%-40%, significantly increasing the backpack's capacity.

[0003] However, existing vacuum compression backpacks have certain drawbacks in use: when clothes are placed into the vacuum area of ​​the backpack, the vacuum area will be filled after some clothes are put in, even in an uncompressed state. If more clothes need to be added, the already filled clothes must be pressed and compressed before the next clothes can be added. This process is cumbersome, time-consuming and laborious. In addition, the existing vacuum compression backpacks have relatively simple functions and lack the function of providing emergency power to electronic devices outdoors or during travel. Therefore, they need to be improved. Utility Model Content

[0016] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0017] Please see Figure 1-7 This utility model provides a technical solution: a vacuum compression backpack with reverse power supply function for mobile phones, including a backpack body 1, a control board 2 installed on the outer wall of the backpack body 1, and a control drive component provided on the control board 2, a partition component for forming a vacuum storage space provided inside the backpack body 1, a shell 11 provided inside the backpack body 1, and a winding component and a fixing component provided inside the shell 11; a keel 8 is installed inside the backpack body 1 near the back, and a binding component is provided on the keel 8; The binding assembly includes a first binding strap 9, a second binding strap 10, a T-shaped block 12, and a T-shaped groove 14. The first binding strap 9 is symmetrically installed on one side of the keel 8, and a T-shaped block 12 is installed at the end of each of the first binding strap 9. The second binding strap 10 is symmetrically installed on the other side of the keel 8, and the ends of the second binding strap 10 are all located inside the housing 11. A rectangular body 13 is installed on the outer wall of the housing 11, and a T-shaped groove 14 is opened in the direction of the extended axis of the top of the rectangular body 13. A T-shaped block 12 is slidably inserted into each T-shaped groove 14. Specifically, during the loading process, after placing the clothing near the keel 8, the first strap 9 and the second strap 10 can be used to wrap around the outside of the clothing. Then, the T-shaped block 12 at the end of the first strap 9 is inserted into the T-shaped groove 14 on the rectangular body 13 to achieve initial binding and fixing of the clothing. This structure can prevent the clothing from being loosely piled up in the backpack, laying the foundation for tightening the clothing through the roll-up component and reducing the space occupied by the clothing in the uncompressed state.

[0018] Furthermore, the winding assembly includes a winding roller 15 and a handle 22. The winding roller 15 is vertically rotatably mounted inside the housing 11, and the handle 22 is mounted on the top of the winding roller 15 outside the housing 11. The end of the second strap 10 passes through a rectangular hole opened on the housing 11 and is wound around the winding roller 15. Specifically, after the clothes are initially secured by the binding assembly, rotating the handle 22 outside the housing 11 will drive the winding roller 15 inside the housing to rotate synchronously. Since the end of the second binding strap 10 is wrapped around the winding roller 15, the winding roller 15 will wind up the second binding strap 10 when it rotates, so that the second binding strap 10 and the first binding strap 9 are tightened together, thereby pressing the clothes inward. This process does not require manual pressing of the clothes. The clothes are pre-compressed by mechanical winding, which makes it convenient to continue to put more clothes into the backpack, solving the problem of the laborious manual pressing required during traditional filling.

[0019] Furthermore, the fixing assembly includes a circular body 16, ratchet 17, limiting tooth 19 and spring 20. The bottom of the take-up roller 15 is located inside the housing 11 and the circular body 16 is installed therein. Multiple ratchet 17 are evenly installed on the outer side of the circular body 16. The inner wall of the housing 11 is equipped with a spring 20 and the end of the spring 20 is equipped with a limiting tooth 19. The limiting tooth 19 is used to limit the ratchet 17. Specifically, when the take-up roller 15 rotates to take up the second strap 10, the bottom circular body 16 rotates synchronously with the take-up roller 15. The ratchet 17 on the outer side of the circular body 16 will squeeze the limiting tooth 19 to cause it to retract briefly. Under the elastic force of the spring 20, the limiting tooth 19 is always in contact with the ratchet 17. After the ratchet 17 rotates past the limiting tooth 19, the limiting tooth 19 will reset and lock the next ratchet 17, forming a one-way limiting structure. This design can effectively prevent the take-up roller 15 from reversing under the tension of the clothes, ensuring that the second strap 10 remains stable after being tightened, and preventing the clothes from becoming loose.

[0020] Furthermore, a sliding rod 18 is installed on the outer wall of the limiting tooth 19, and a pull handle 21 is installed at the end of the sliding rod 18 through the housing 11. A spring 20 is sleeved on the sliding rod 18. Specifically, when it is necessary to loosen the clothing, pull the handle 21, which drives the sliding rod 18 to drive the limiting tooth 19 to compress the spring 20 and disengage from the ratchet 17, thus releasing the restriction on the circular body 16. At this time, the handle 22 can be rotated in the opposite direction to release the second strap 10, making it convenient to take out the clothing.

[0021] Furthermore, the partition assembly includes a sealing partition 6 and a zipper 7 with sealing function. The sealing partitions 6 are installed on both inner side walls of the backpack body 1, and the sides of the sealing partitions 6 that are close to each other are connected by the zipper 7 with sealing function. The shell 11 is located in the space formed by the sealing partitions 6 and the backpack body 1. Specifically, the sealing layer 6 is made of flexible sealing material and fits against the inner wall of the backpack body 1 to form an independent vacuum storage space for storing fluffy items such as clothes. The zipper 7 with sealing function can block the flow of air between the vacuum area and the outside after closing, ensuring the airtightness of the space. The shell 11 is located in this vacuum area, which does not affect the placement of clothes, and can protect the internal winding and fixing components from damage caused by the clothes, ensuring the stable operation of the mechanical structure and providing a sealed environment for subsequent vacuum compression.

[0022] Furthermore, the control drive component includes a vacuum pump 3, a data cable connector 4, and a battery mounting slot 5. The control board 2 is equipped with multiple data cable connectors 4 of different specifications. The control board 2 has a battery mounting slot 5, and a lithium battery is placed in the battery mounting slot 5. The control board 2 is equipped with a vacuum pump 3, and the suction end of the vacuum pump 3 is connected to the vacuum area inside the backpack body 1 through a pipe. Specifically, the lithium battery powers the vacuum pump 3 and the data cable connector 4. When the vacuum pump 3 is working, it can extract air from the vacuum area through the pipe, so that the clothes are further compressed under atmospheric pressure to reduce the volume. The data cable connector 4 of different specifications can be adapted to different models of mobile phones to realize the reverse power supply function of the mobile phone, and provide emergency charging for the mobile phone outdoors or during travel. When you need to charge your phone, connect the phone data cable to the corresponding data cable connector 4. The lithium battery in the battery installation slot 5 will then power the phone. At the same time, the phone can also charge the lithium battery. The lithium battery will be in a depleted state when it is not used for a long time. In terms of the power supply system, the battery mounting slot 5 adopts an anti-reverse buckle design. The built-in lithium battery capacity can be configured according to the needs and supports repeated charging and use. The lithium battery is connected to the internal circuit of the control board 2 through wires to provide a stable DC power supply for the vacuum pump 3 and the data line connection port 4. The battery mounting slot 5 is equipped with a dustproof and waterproof cover to prevent outdoor rain and dust from entering and damaging the battery. The data cable connector module 4 is equipped with mainstream mobile phone interfaces such as Type-C, Micro-USB, and Lightning, covering common mobile phone models on the market. The interface integrates an overcharge protection chip and a current regulation module. When the phone battery is detected to be fully charged or the input current is abnormal, the power supply will be automatically cut off to prevent the phone battery from being damaged by overcharging. The outside of the interface is equipped with a flip-up silicone dust plug, which can be closed when not in use to isolate dust and moisture. The vacuum pump 3 is driven by a miniature brushless motor, which can quickly extract air from the vacuum area formed by the sealing layer 6 and the backpack body 1. The vacuum pump 3 is connected to the control board 2 through a relay. The control board 2 has an independent vacuum pump start / stop button on its surface. When pressed, the vacuum pump starts. During the pumping process, the built-in pressure sensor monitors the air pressure in the vacuum area in real time. When the air pressure drops to the preset value, the vacuum pump automatically stops working to avoid over-pumping and damage to the sealing layer. If the air pressure rises above the threshold, the vacuum pump can automatically restart to replenish air and maintain the compressed state. The surface of the control board 2 is also equipped with multi-functional indicator lights: the lithium battery power indicator light displays the remaining power through LED lights, and flashes red light to remind charging when the power is low; the vacuum pump working indicator light flashes green when pumping air and stays on when it is finished; the power supply indicator light lights up when the data cable connection port is supplying power to the outside, and turns red to warn of abnormality. These indicator lights intuitively reflect the operating status of the equipment, making it convenient for users to keep track of the function status in real time. The design of this control drive component not only enables efficient compression of clothing through a vacuum pump, but also provides emergency power to mobile phones through lithium batteries and multiple interface specifications. Furthermore, through multiple safety protections and intelligent control functions, it ensures stability and safety for outdoor use, significantly enhancing the backpack's multi-functional practicality.

[0023] The workflow of this embodiment is as follows: First, unzip the zipper 7 with sealing function, put the clothes into the vacuum area formed by the sealing compartment 6 and the backpack body 1. After a certain amount of clothes are placed, wrap the first strap 9 and the second strap 10 around the clothes, insert the T-shaped block 12 into the T-shaped groove 14 to complete the initial binding, then turn the handle 22, and the winding roller 15 rotates and winds up the second strap 10, so that the strap is tightened and the clothes are compacted. At this time, the limiting tooth 19 in the fixing component is locked by the ratchet tooth 17 under the action of the spring 20 to prevent the winding roller 15 from reversing, keep the clothes in a tight state, and make it convenient to continue to fill more clothes. After filling, close the sealing zipper 7 and start the vacuum pump 3. The vacuum pump 3 extracts air from the vacuum area through the pipe, further compressing the clothing under atmospheric pressure to reduce its volume. When you need to charge your mobile phone, connect the mobile phone data cable to the corresponding data cable connector 4. The lithium battery in the battery installation slot 5 can then power the mobile phone. At the same time, the mobile phone can also charge the lithium battery. The lithium battery will be in a depleted state when it is not used for a long time.

[0024] When you need to take out the clothes, first pull the handle 21 to disengage the limiting tooth 19 from the ratchet 17, then rotate the handle 22 in the opposite direction to release the second strap 10, and then pull open the zipper 7 with sealing function to take out the clothes.
