Description

Technical Field

[0001] The utility model relates to the technical field of backpacks, more specifically to an inflatable safety airbag backpack. Background Art

[0002] Backpacks are a common daily necessity and are widely used in life. Whether it is at work, traveling, or going out for sports, backpacks are used, so the requirements for backpacks are also increasing. The first is the ventilation function of the backpack. The backpacks on the market are generally carried on the shoulders with two shoulder straps. The back of the user will be in contact with the back of the backpack over a large area. When carrying for a long time, the back of the human body is close to the backpack for a long time and cannot be ventilated. It will sweat and make the back feel uncomfortable. In order to achieve the ventilation function, many existing backpacks will be equipped with a sponge layer to achieve ventilation and improve the softness and comfort through the sponge layer. However, it is obvious that the ventilation effect of the sponge is limited and cannot perfectly solve the ventilation problem of the backpack. In addition, some backpacks on the market are equipped with inflatable airbags, but the structure of the inflatable airbags is simple and cannot achieve a good ventilation effect. The second is the safety function of the backpack. When outdoors, many spontaneous combustion disasters and common drowning are often encountered. The general backpack has a single function and only has the function of loading items and does not have a safety protection function. It cannot provide help when danger occurs. In view of this, the inventors propose an inflatable safety airbag backpack to solve the above problem. The backpack has an inflatable airbag built into it, and the inflatable airbag is provided with a concave-convex structure and a plurality of air holes, which can enhance the breathability and softness of the backpack and improve comfort.

[0003] In order to solve the problem that the back of a human body is prone to stuffiness and sweating and causing discomfort when carrying a backpack for a long time, and to improve the ventilation effect of the backpack, a Chinese patent (authorization announcement number: CN220713166U) discloses a breathable and load-reducing backpack. The utility model includes a bag body, on which a shoulder strap is fixedly installed; a first buffer air cushion is installed on the inner side of the shoulder strap, and a second buffer air cushion is installed on the back of the bag body; a plurality of air bags are formed on the first buffer air cushion and the second buffer air cushion, and the plurality of air bags are arranged in a rectangular array with ventilation gaps formed between adjacent air bags; a manual pressing pump is provided on the first buffer air cushion and the second buffer air cushion, and the manual pressing pump inflates the plurality of air bags, and an air release port is provided on the first buffer air cushion and the second buffer air cushion, and the air release port and the plurality of air bags are connected to each other, and an air release valve is installed in the air release port; ventilation gaps are formed between the plurality of air bags of the utility model, which can avoid large-area contact and achieve good ventilation and air permeability effects.

[0004] There are still some deficiencies in the application of this solution. Since the backpack is used in many scenarios, especially during outdoor sports, effective protection for the inflatable airbag is required. Otherwise, it is very easy for the airbag to be punctured, resulting in the loss of the ventilation function. Also, as the use range of the backpack continues to expand, many people will place some items that need ventilation into the backpack. Therefore, the backpack also needs to have internal and external ventilation functions. Therefore, it is necessary to improve the structure of the backpack by adding an inflatable airbag, which can not only achieve an effective ventilation and buffering effect, but also realize the internal and external ventilation of the backpack, further improving the practicality of the backpack. Summary of the Invention

[0005] The present invention discloses an inflatable airbag backpack, and its main purpose is to overcome the above-mentioned deficiencies and drawbacks existing in the prior art.

[0006] The technical solution adopted by the present invention is as follows:

[0007] An inflatable airbag backpack includes a backpack body and an inflatable airbag. A gasbag cavity is provided at the rear side of the backpack body, and the inflatable airbag is placed inside the gasbag cavity. The inflatable airbag has a "field" - shaped structure and circular ventilation holes are provided at the four corners. The side surface of the inflatable airbag has an "S" - shaped concave - convex structure. A ventilation mesh cloth is provided at the rear side of the gasbag cavity, and a ventilation mesh cloth cavity with an upward - opening is provided at the front side. An elastic baffle is detachably installed in the ventilation mesh cloth cavity.

[0008] Furthermore, mesh bags are provided on the left and right sides of the backpack body, and a tightening strap is provided at the top of the mesh bag.

[0009] Furthermore, an inflation port is provided at the lower part of one side of the inflatable airbag. An inflation tube is adaptably provided at the inflation port, and a hand - held rubber inflation bag is provided at the end of the inflation tube. The hand - held rubber inflation bag is movably placed inside the mesh bag.

[0010] Furthermore, the inflatable airbag can be inflated and deflated through the hand - held rubber inflation bag. A pressure sensor is provided on one side of the hand - held rubber inflation bag, and a switch valve is provided on the other side.

[0011] Furthermore, a pipe - passing hole is provided at the bottom of the mesh bag, and the inflation tube passes through the pipe - passing hole movably to be connected with the hand - held rubber inflation bag in the mesh bag.

[0012] Furthermore, several ventilation holes are provided on the elastic baffle.

[0013] From the above description of the present invention, it can be seen that compared with the prior art, the advantages of the present invention are:

[0014] In the present utility model, an inflatable airbag is first内置 in an airbag cavity at the rear side of the backpack body. Compared with the exposed setting of the airbag, it can better protect the airbag and avoid being punctured. Then, a number of circular ventilation holes are arranged on the plane of the inflatable airbag, and the side surface of the inflatable airbag呈 an "S"-shaped concave-convex structure after inflation. Combined with the fact that a ventilation mesh cloth is provided at the rear side of the backpack body and a ventilation mesh cloth cavity with an upward opening is provided at the front side, through this setting, the internal and external air can circulate, achieving a good ventilation effect between the backpack body and the human back, improving the comfort of the backpack. At the same time, an elastic baffle is detachably provided in the ventilation mesh cloth cavity, and it can be selected whether to use it according to the attributes of the items in the backpack. The elastic baffle can prevent hard objects from puncturing the inflatable airbag and the human back, providing good safety protection. Finally, after the inflatable airbag is inflated, in case of the dangerous situation of drowning outdoors, the inflatable airbag can provide a certain buoyancy to help the user float to get out of trouble, further improving the safety performance. The structure of the present utility model is novel, the design is ingenious, and the practicability is strong, which is suitable for popularization. Brief Description of the Drawings
