[0001] This utility model relates to the field of compression backpack technology, specifically a compression backpack with adjustable vacuum intensity. Background Technology

[0002] A vacuum compression backpack is a type of backpack that compresses and stores items by removing internal air. Its core principle is to reduce the volume of items by utilizing a vacuum environment. It also has functions such as portability and protection and is widely used in outdoor, travel, and storage scenarios.

[0003] An existing patent (publication number: CN209965553U) discloses an outdoor backpack with a vacuum compression bag device. This utility model not only facilitates the organization of luggage but also meets the needs of people with backpacks of different sizes, making it economical and practical. Furthermore, it can be powered by a solar panel or USB interface, enabling a miniature electric air pump to automatically pump air, saving energy, saving space, and ensuring sufficient power.

[0004] To address the aforementioned issues, while existing patents have proposed solutions that can achieve vacuum pumping through the use of components such as miniature electric air pumps, the pumping intensity cannot be adjusted according to the loaded object during actual use, resulting in a limited and singular effectiveness.

[0028] To make the above-mentioned objectives, features and advantages of this utility model more readily understood, the specific embodiments of this utility model will be described in detail below with reference to the accompanying drawings.

[0029] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Those skilled in the art can make similar extensions without departing from the spirit of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0030] Secondly, the term "an embodiment" or "embodiment" as used herein refers to a specific feature, structure, or characteristic that may be included in at least one implementation of the present invention. The phrase "in one embodiment" appearing in different places in this specification does not necessarily refer to the same embodiment, nor is it a single embodiment or an embodiment selectively excluded from other embodiments.

[0031] Example 1:

[0032] Please see Figures 1-3 This is the first embodiment of the present invention.

[0033] This embodiment provides a compression backpack with adjustable vacuum strength, including a shoulder strap 1, a first storage cavity 2 fixedly installed at the front end of the shoulder strap 1, a conventional zipper 3 embedded in the outer wall of the first storage cavity 2, and a compression mechanism 4 provided inside the first storage cavity 2.

[0034] The compression mechanism 4 includes a vacuum storage bag 401, which is fixedly installed inside the first storage cavity 2. A first airtight zipper 402 is embedded at the front end of the vacuum storage bag 401. An air extraction hole 403 is provided on one side of the first airtight zipper 402 at the front end of the vacuum storage bag 401. A PVC one-way valve 404 is embedded inside the air extraction hole 403. An electric air pump 405 extends through the air extraction hole 403. A control terminal 406 is fixedly installed at the other end of the electric air pump 405. A connecting block 407 is fixedly installed at one end of the electric air pump 405 that passes through the air extraction hole 403. A fixing frame 408 is fixedly installed inside the connecting block 407. A micro motor 409 is fixedly installed on the outer wall of the fixing frame 408. A drive rod 410 is fixedly installed at the power output end of the micro motor 409. An adjusting block 411 is fixedly installed at one end of the drive rod 410.

[0035] Furthermore, the electric vacuum pump 405 can correspond to the PVC one-way valve 404 and automatically perform vacuuming to compress the vacuum storage bag 401. The airflow space can be adjusted by the adjusting block 411 and the fixing frame 408 according to the required vacuum intensity, thereby improving the overall flexibility.

[0036] Specifically, the electric air pump 405 extends into the interior of the air extraction hole 403, and the air extraction hole 403 is threadedly connected to the connecting block 407.

[0037] Furthermore, the air extraction hole 403 and the connecting block 407 are threaded together, which facilitates disassembly and assembly for air extraction, and allows for air extraction of other parts after the air extraction is completed.

[0038] Specifically, the fixed frame 408 and the adjusting block 411 are closely fitted together, and the adjusting block 411 and the fixed frame 408 form a sliding structure.

[0039] Furthermore, the adjusting block 411 fits tightly against the fixing frame 408, thereby allowing the adjustment of the vacuum intensity through the adjustment of the reserved groove after stacking.

[0040] In use, the first storage cavity 2 is closed by a conventional zipper 3. After the vacuum storage bag 401 is filled with an object, it is closed by the first airtight zipper 402 to achieve a seal. The connecting block 407 is threadedly connected to the air extraction hole 403. The electric vacuum pump 405 is connected to the PVC one-way valve 404 to facilitate vacuuming operations. With the adjustment of the micro motor 409, the adjusting block 411 is driven by the drive rod 410 to rotate along the fixed frame 408, and the vacuum intensity is adjusted as needed. The control terminal 406 has a rechargeable battery and a control module to provide power to the electric vacuum pump 405 and the micro motor 409 and to control them.

[0041] In summary, by controlling the electric vacuum pump 405 and the micro motor 409 through the control terminal 406, the adjusting block 411 can be rotated to fit the fixed frame 408 according to the object or needs during vacuuming. The reserved grooves generated between them after overlapping allow gas to flow, thereby adjusting the vacuum intensity. In addition, the threaded connection between the connecting block 407 and the vacuum hole 403 facilitates disassembly and assembly, improving the overall applicability and flexibility.

[0042] Example 2:

[0043] Please see Figure 1 , Figure 4 and Figure 5 This is the second embodiment of the present utility model.

[0044] Specifically, a second storage cavity 5 is fixedly installed at the front end of the first storage cavity 2, and a split mechanism 6 is provided inside the second storage cavity 5.

[0045] Furthermore, the second storage compartment 5 increases the overall storage space of the backpack, allowing it to carry more items.

[0046] Specifically, the split mechanism 6 includes a reinforcing rope 601, which is fixedly installed inside the second storage cavity 5, and a slider 602 is slidably connected to the outside of the reinforcing rope 601.

[0047] Furthermore, the reinforcing rope 601 and the slider 602 are made of the same fabric fibers, which can form a sliding structure to adjust the position and avoid being too stiff to affect the comfort of wearing the backpack.

[0048] Specifically, a split storage bag 603 is fixedly installed at one end of the slider 602, and a connecting part 604 is fixedly installed at the front end of the split storage bag 603. A second airtight zipper 605 is embedded in the outer wall of the connecting part 604.

[0049] Furthermore, multiple separate storage bags 603 can be vacuumed through the air extraction hole 403, and are equipped with a second airtight zipper 605 for easy placement of items and to achieve sealing.

[0050] In use, by strengthening the cooperation of the rope 601 and the slider 602, the position of the split storage bag 603 after carrying items can be adjusted. The placement can be adjusted according to the amount of items loaded to avoid mutual compression and to prevent items from falling off and being lost when not loaded. The connecting part 604 is made of the same material as the split storage bag 603 and is opened and closed by the second airtight zipper 605 to insert items.

[0051] In summary, the multiple separate storage bags 603 allow for the categorized storage of items and also enable vacuum sealing. With the cooperation of the reinforcing rope 601 and the slider 602, the separate storage bags 603 can be adjusted in position according to the amount of items stored, avoiding fixed positions that cause them to squeeze each other and preventing them from easily falling off and getting lost when not loaded with items.

[0052] Example 3:

[0053] Please see Figure 1 and Figure 6 This is the second embodiment of the present utility model.

[0054] Specifically, a third storage cavity 7 is fixedly installed at the front end of the second storage cavity 5, and an auxiliary mechanism 8 is provided inside the third storage cavity 7.

[0055] Furthermore, the third storage compartment 7 further enhances the backpack's storage space, allowing it to hold more items.

[0056] Specifically, the auxiliary mechanism 8 includes a Velcro 801, which is embedded in the front end of the third storage cavity 7. A reinforcing plate 802 is embedded inside the third storage cavity 7, and a fastening ring 803 is embedded in the outer wall of the reinforcing plate 802. A fastener 804 protrudes from the front end of the fastening ring 803.

[0057] Furthermore, two fastening rings 803 are rotatably connected via a connecting shaft and, together with fasteners 804, form a clamp.

[0058] When in use, the Velcro 801 facilitates the opening and closing of the third storage cavity 7. After the two fastening rings 803 are rotated, they are secured by the fasteners 804, thereby securing the umbrella handle and preventing loosening under the support of the reinforcing plate 802. This allows the umbrella to be fixed in place, freeing the wearer's hands in rainy weather.

[0059] In summary, the umbrella can be secured by the combination of the buckle 803 and the fastener 804, thus freeing the wearer's hands and improving the functionality and convenience of the entire backpack. This is especially beneficial for hiking in the rainy season, as it frees up the hands to prevent danger.
