Description

TECHNICAL FIELD

[0001] The utility model relates to the field of backpacks, especially a backpack with a compression bag. BACKGROUND

[0002] A backpack is a tool commonly used by people when they travel and carry articles, which has storage spaces of different sizes to facilitate users to place various articles. However, when objects, especially clothes and other articles with certain fluffy characteristics, are stacked in the storage space, space is inevitably wasted, resulting in a decrease in the storage capacity. Therefore, a backpack with a compression bag has appeared on the market, that is, a compression bag or an airtight bag that can be vacuum compressed is arranged in the storage space, clothes are placed in the vacuum bag or the compression bag, and then a vacuum compression device is used to vacuum compress the clothes, which can greatly release the storage space. However, since the compression bag will have two states of expansion and contraction in the storage space, the compression bag is generally arranged at the middle part of the bag body so that when the compression bag expands, the front and rear sides of the compression bag can fully stretch without being limited by the front and rear inner walls of the storage space. However, if the compression bag is fixed in the storage space and is in the state of contraction, a gap will exist between the rear side of the compression bag and the rear inner wall of the storage space, causing the rear width of the backpack to be concave inward, which is not beautiful and causes waste of the storage space. At the same time, the compression bag or the airtight bag after compression will become a heavy block. If a gap exists between the rear side of the compression bag and the rear inner wall of the storage space, the compression bag will shake inside the bag body when the user carries the backpack, which will increase the burden of the user and reduce the carrying experience.

[0024] As Figures 1-5As shown, the utility model discloses a backpack with compression bag, including bag body 1 and the belt 100 of setting on bag body 1. The belt 100 is used for the user to carry bag body 1. The bag body 1 is equipped with the three -dimensional accommodation cavity 10 of accommodating article inside, as shown in the drawing of specification, this embodiment has adopted the double -shoulder bag as the example, and the accommodation cavity 10 is the main storage cavity of double -shoulder bag, i. e. the cavity that the most object is stored. The three -dimensional accommodation cavity 10 includes a relatively flat rear wall 11, the circumferential edge of rear wall 11 is fixedly connected with annular side wall 12, the end of side wall 12 away from rear wall 11 is front wall 13, the rear wall 11 of the embodiment refers to the inner wall of three -dimensional accommodation cavity 10 close to the back of bag body. The back of bag body refers to the side close to the back of user. With the back of bag body, bag body is provided with front cover 3 for entering the three -dimensional accommodation cavity 10 from the outside of bag body. The circumferential edge of front cover 3 is provided with second fixed section 31 and second removable section 32, the front cover 3 is fixedly connected with bag body 1 through second fixed section 31, and is removably connected with bag body 1 through second removable section 32. For the field of luggage, the fixed connection mode generally includes hot pressing, sewing and the like. The removable connection mode of second removable section 32 of front cover of this embodiment and bag body 1 is zipper connection. When front cover 3 is connected with bag body 1 through zipper, the inner side wall group of front cover forms the front wall 13 of three -dimensional accommodation cavity 10.

[0025] Further, the three -dimensional accommodation cavity 10 is further provided with a compression bag 2 that can be expanded, the compression bag 2 includes at least one relatively flat connecting surface, the flat connecting surface facilitates the connection with the rear wall of the three -dimensional accommodation cavity, and at the same time, the compression bag can be kept in close contact with the rear wall in the inflation or deflation state, thereby avoiding the gap between the compression bag and the rear wall after compression, and wasting the storage space. Further, the connecting surface and the rear wall 11 of the three -dimensional accommodation cavity can be removably connected or not. Since the bag body 1 and the compression bag 2 are usually made of flexible material, the removable mode generally includes buckles, magic tapes, zippers and the like commonly used in the field of luggage, and the non-removable mode includes hot pressing, sewing and the like. The compression bag 2 is provided with an opening 21 into the closed bag body, a locking member 22 for closing the opening 21, and an air valve 23. The three -dimensional accommodation cavity 10 is provided with an intercepting portion in front of the compression bag 2. The intercepting portion is mainly used to limit the movement of the compression bag 2 after compression, so that it is kept in close contact with the rear wall 11 of the three -dimensional accommodation cavity, and the shaking feeling in the cavity is reduced, thereby providing comfort for the user and making it more labor-saving to carry. The intercepting portion is provided with a first fixed section fixedly connected with the side wall of the three -dimensional accommodation cavity and a first removable section removably connected with the side wall 12 of the three -dimensional accommodation cavity. The first fixed section is used to fix the intercepting portion in the three -dimensional accommodation cavity 10, so as to avoid loss and facilitate the quick connection of the first removable section with the side wall 12 of the three -dimensional accommodation cavity. When the first removable section is removed, the user can normally access the compression bag 2 to store or inflate or deflate the object.

[0026] The compression bag 2 is composed of a relatively flat first plane 20 and a half bag body 21 connected with the circumferential edge of the first plane 20; since the compression bag 2 is made of flexible material, the half bag body 21 can directly conform to the first plane in the compression state without placing articles. The connecting surface is adapted to the profile of the rear wall 11 of the accommodating cavity. At this time, the thickness of the compression bag is almost negligible. The backpack of the embodiment is equivalent to a common backpack.

[0027] Further, the embodiment discloses a specific structure of the intercepting part, which comprises a layer of mesh cloth 41; the mesh cloth 41 is distributed with a plurality of hollow meshes, and the first fixed section 410 and the first removable section 411 are connected with the circumferential edge of the mesh cloth and the side wall 12 of the accommodating cavity. The mesh cloth 41 divides the accommodating cavity 10 into two cavities in front and back, which can not only limit the movement of the compression bag 2 after compression, but also can be used as a spacer for articles, and can play a role in article classification, such as separating clean and dirty clothes. Of course, as shown in the drawings, in another embodiment, the intercepting part can also be a plurality of elastic belts 42; one end of the elastic belt is the first fixed section 420, and the other end is the first removable section 421, which are respectively connected to the opposite side walls of the accommodating cavity.

[0028] Further, the half bag body 21 comprises a second plane 251 opposite to the first plane 24; the second plane 251 is integrally connected with a left side surface 252, a right side surface 253, an upper side surface 254 and a lower side surface 255; the left side surface 252, the right side surface 253, the upper side surface 254 and the lower side surface 255 are sealingly connected two by two to form the annular side wall of the half bag body 25; the connecting surface is the first plane 24 or the second plane 251. As shown in the drawings, the connecting surface of the embodiment is the first plane 24. The circumferential edge of the first plane 24 is connected with the edges of the left side surface 252, the right side surface 253, the upper side surface 254 and the lower side surface 255, and then is sewn to the rear wall 11 of the accommodating cavity. The opening 21, the locking member 22 and the air valve 23 are distributed on the second plane 251. Of course, in another embodiment, the connecting surface is the second plane 251, and the opening 21, the locking member 22 and the air valve 23 are distributed on the first plane 24.

[0029] Further, as shown in the drawings, the second fixed section 31 of the embodiment is arranged in the same direction as the first fixed section 410, and is arranged on the left side of the bag body; the second removable section 32 is arranged in the same direction as the first removable section 411, and is arranged on the upper, right and lower sides of the bag body. Of course, in some embodiments, the fixed sections and removable sections of the front cover and the intercepting part are not arranged in the same direction, for example, the second fixed section of the front cover is arranged at the bottom of the bag body; and the second removable section is arranged on the upper, left and right parts of the bag body. Arrangement in the same direction is more in line with the thinking inertia of the user, and is convenient for the user to operate.

[0030] Further, another compression bag can be directly placed in the backpack, that is, the other compression bag has no connection with the accommodating cavity 10. The other compression bag has the same composition as the compression bag 2, and has a relatively flat first plane and a half bag body sealed and connected with the circumferential edge of the first plane. The other compression bag can be used for item packaging. Since the thickness of the compression bag without items is almost negligible, the compression bag almost does not occupy space in the accommodating cavity, and can be used as needed in daily life. When in use, the compressed other compression bag can be placed between the front cover and the intercepting part.

[0031] Further, the number of air valves of the compression bag is at least one, and the air outlet effect is better. If the air outlet device is out of power, the user can use the hand squeezing method to squeeze the air in the compression bag.

[0032] For those skilled in the art, various corresponding changes and deformations can be made according to the above described technical solutions and concepts, and all these changes and deformations should belong to the protection scope of the present application.
