DETAILED DESCRIPTION

[0027] In order to make the purpose, technical solution and advantages of the present invention more clear, the implementation mode of the present invention will be further described in detail below in conjunction with specific embodiments and drawings.

[0028] A backpack with back ventilation function comprises a bag body 1. The back of the bag body 1 is provided with a ventilation module 2, and the ventilation module 2 is arranged in an interlayer of the back.

[0029] The ventilation module 2 includes a sealing bag 6, which can be a hard plastic structure with a hollow interior. A ventilation area is provided on the first side of the sealing bag 6, and a fan 9 is provided on the bottom of the second side opposite to the first side, which is fixed to the ventilation module 2 by heat sealing or gluing. The fan 9 is staggered with the ventilation area, and is used to suck the air in the sealing bag 6 and the air entering through the ventilation area to the outside.

[0030] In a feasible embodiment, the sealed bag 6 may also be a soft sealed bag, and a ventilation window is further provided on the sealed bag 6. A mesh air-permeable plate is coated inside the sealed bag 6, and the air-permeable plate is used to support the sealed bag 6 to maintain a hollow interlayer space, and is combined with the ventilation window to form a first ventilation hole 7. For example, the air-permeable plate is a 3D supporting mesh material with a thickness of 4 mm to 10 mm, thereby supporting the inside of the sealed bag 6 so that air can flow freely inside.

[0031] Compared with the defect of the blowing method in the prior art that the backpack makes the backpack look bloated and uncomfortable, the ventilation module 2 with a suction structure in this embodiment has a more compact structure. It can extract the heat from the user's back after the user puts on the backpack, reducing the possibility of hot air blowing to the back due to the heat of the fan 9. The suction function can also be used to reduce back sweat. It is suitable for user groups of different body shapes and improves the comfort of wearing the backpack.

[0032] The ventilation area includes a first ventilation hole 7 and a second ventilation hole 8, the aperture of the first ventilation hole 7 is larger than the aperture of the second ventilation hole 8, and the distance between the first ventilation hole 7 and the fan 9 is larger than the distance between the second ventilation hole 8 and the fan 9;

[0033] A third ventilation hole 17 is further provided above the second surface of the sealing package 6 , and the distance between the third ventilation hole 17 and the fan 9 is greater than the distance between the first ventilation hole 7 and the fan 9 .

[0034] Since the fan 9 is located below the ventilation module 2, if the ventilation openings are uniform, the air intake and suction force of the air inlet holes 12 close to the fan 9 will be greater than those farther away from the fan 9, which will reduce the uniformity of the overall ventilation. The use of first ventilation holes 7 and second ventilation holes 8 with uneven sizes in the upper and lower parts can make the overall air intake and suction force more balanced.

[0035] In some embodiments, the first ventilation holes 7 include meshes arranged in a honeycomb shape or a prismatic shape, and the second ventilation holes 8 include circular holes arranged in a lattice shape.

[0036] In some embodiments, a plurality of the first ventilation holes 7 and a plurality of the second ventilation holes 8 are provided respectively, and a distance between two adjacent first ventilation holes 7 is greater than a distance between two adjacent second ventilation holes 8 .

[0037] In some embodiments, a support module 3 is also included, and the support module 3 is used to support the ventilation module 2. A fixing groove 10 is provided below the first surface of the support module 3 corresponding to the installation position of the fan 9, and an exhaust port 11 is provided on the outer side of the fixing groove 10. An air inlet 12 is provided above the support module 3, and the air inlet 12 is provided at the position corresponding to the third ventilation hole 17.

[0038] In some embodiments, one end of the air inlet hole 12 opens toward the first surface of the ventilation module 2 , and the other end penetrates the second surface of the support module 3 and extends upward to form an air inlet groove 13 .

[0039] In some embodiments, the edge of the support module 3 is larger than the ventilation module 2, and a foam plate 14 with a thickness greater than that of the ventilation module 2 is also provided at the edge of the first surface of the support module 3. By utilizing the supporting and protective function of the foam plate 14, the ventilation module 2 is enclosed inside the support module 3 to form a similar embedded structure.

[0040] In some embodiments, the second surface of the support module 3 is further provided with a wiring groove 15 for leading out a wire, such as a USB power cable, from the support module 3 to connect the fan 9 to a power source, such as a power bank or a battery.

[0041] In some embodiments, a hard plastic sheet 16 is provided below the second surface of the support module 3 corresponding to the installation position of the fan 9 , and the hard plastic sheet 16 is bonded to the foam board 14 to protect and support the position of the fan 9 .

[0042] In some embodiments, the back of the bag body 1 is further provided with a contact surface 4 and a shoulder strap 5, wherein the contact surface 4 is a porous mesh breathable structure, such as a sandwich mesh structure, and the contact surface 4 is sewn onto the bag body 1 after being bonded to the first surface of the ventilation module 2. The shoulder strap 5 is also provided with a switch for controlling the fan 9, and the switch is electrically connected to the fan 9 so that the user can conveniently control the opening and closing of the fan 9 according to actual needs when carrying the backpack.

[0043] Optionally, a heat-sealed edge of about 1 cm is left at the edge of the ventilation module 2 and is sewn to the contact surface 4 of the package body 1 by means of stitches.

[0044] When in use, firstly, the power cord of the fan 9 needs to be connected in the bag, and a power bank or other power source can be used. A switch button of the fan 9 is provided on the shoulder strap of the backpack. By pressing the button, the ventilation fan 9 is turned on. At this time, air will enter the sealed bag 6 from the ventilation area of ​​the ventilation module 2, pass through the fan 9, and be discharged from the exhaust hole. After a person puts on the backpack, the heat emitted from the back and the sweat secreted will also be taken away by the air and discharged from the exhaust hole.

[0045] Due to the different body shapes of different people, the coverage of the ventilation part on the back of the backpack is different after the backpack is put on. When the ventilation part is not completely covered, the air will enter from the uncovered air inlet 12, and when the ventilation part of the back is completely covered, the air will still enter from the top air inlet 12. At this time, the incoming air will flow from top to bottom. When the flowing air passes through the ventilation part of the back, it will also take away the heat and sweat of this part, thereby achieving a good effect on users of any body shape.

[0046] The above are only preferred embodiments of the utility model, and are not intended to limit the utility model in other forms. Any technician familiar with the profession may use the above disclosed technical content to change or modify it into an equivalent embodiment with equivalent changes. However, any simple modification, equivalent change and modification made to the above embodiments based on the technical essence of the utility model without departing from the technical solution of the utility model still belongs to the protection scope of the technical solution of the utility model.
