Description

Technical Field

[0001] The utility model relates to the technical field of daily necessities, in particular to a backpack with a refrigeration device. Background Art

[0002] A backpack is a bag used to carry personal items. There are many commonly used types of backpacks, including wallets, key bags, clutches, handbags, school bags, shoulder bags and briefcases, etc. They are indispensable items in our daily lives. However, when the weather temperature is high, the place where the backpack contacts the human body cannot dissipate heat, which can easily cause the wearer to sweat. The larger the contact area, the more severe the sweating. Sweat will stain and odor the backpack fabric and cause discomfort to the backpack wearer. Utility Model Content

[0003] The utility model aims to provide a backpack with a refrigeration device, which can solve the problem that when the backpack is used in high temperature weather, the place where the backpack contacts the human body cannot dissipate heat, which easily causes the wearer to sweat, causes stains and peculiar smell on the backpack fabric, and brings discomfort to the backpack wearer.

[0004] In order to solve the above problems, the technical solution adopted by the utility model is: this backpack with a refrigeration device includes a backpack body, and a ventilation plate and a fan are sequentially arranged outside the backpack body, one side surface of the ventilation plate is in close contact with the outer surface of the backpack body, and the other side surface of the ventilation plate is spaced apart from the fan, and the fan is connected to a mobile power supply through a power cord.

[0005] In the above technical solution, a more specific technical solution can also be: the fan includes a shell formed by a base plate and a mesh cover, and the shell is provided with fan blades driven by a motor. The motor is installed on the base plate through a motor seat, and the base plate is located on a side close to the ventilation plate.

[0006] Furthermore, a connecting plate is provided on a surface of one side of the bottom plate close to the ventilation plate via a connecting ring.

[0007] Furthermore, the distance between the ventilation plate and the connecting plate is 2 cm to 3 cm.

[0008] Furthermore, the ventilation plate is connected to the backpack body via a first connecting member, and the ventilation plate is connected to the connecting plate via a second connecting member.

[0009] Furthermore, the ventilation plate is provided with a first ventilation hole, and the bottom plate and the connecting plate are provided with a second ventilation hole.

[0010] Furthermore, the backpack body is provided with a backpack strap.

[0011] Due to the adoption of the above technical solution, the utility model has the following beneficial effects compared with the prior art:

[0012] When the utility model is in use, the backpack body is fixed to the wearer through the backpack strap, the mobile power supply provides power support to the fan, the fan contacts the body of the wearer to separate the backpack body from the wearer, and then the fan motor is started to drive the fan blades to rotate, so that air flows, the heat of the backpack and the wearer's body is dissipated faster, the temperature is lowered, and the wearer's body sweating is reduced, thereby reducing the stain and odor of the backpack fabric, and making the wearer feel cool and comfortable. BRIEF DESCRIPTION OF THE DRAWINGS

[0013] Figure 1 It is a structural schematic diagram of the utility model;

[0014] Figure 2 yes Figure 1 Sectional view at AA. DETAILED DESCRIPTION

[0015] The utility model is further described in detail below in conjunction with the accompanying drawings:

[0016] like Figure 1 and Figure 2 The backpack with a refrigeration device shown includes a backpack body 1, and a ventilation plate 2 and a fan are sequentially arranged outside the backpack body 1. One side surface of the ventilation plate 2 is in close contact with the outer surface of the backpack body 1, and the other side surface of the ventilation plate 2 is spaced apart from the fan. The fan is connected to a mobile power supply 4 via a power cord 3.

[0017] The fan includes a shell formed by a base plate 5 and a mesh cover 6, and a fan blade 8 driven by a motor 7 is arranged in the shell. The motor 7 is installed on the base plate 5 through a motor seat. The base plate 5 is located on the side close to the ventilation plate 2. The base plate 5 is provided with a connecting plate 10 on the surface of the side close to the ventilation plate 2 through a connecting ring 9. The distance L between the ventilation plate 2 and the connecting plate 10 is 2 cm to 3 cm. The ventilation plate 2 is provided with a first ventilation hole, and the base plate 5 and the connecting plate 10 are provided with a second ventilation hole.

[0018] The ventilation plate 2 is connected to the backpack body 1 through a first connecting member 11, and the ventilation plate 2 is connected to the connecting plate 10 through a second connecting member 12. In this embodiment, the first connecting member 11 is a screw, and the second connecting member 12 is a bolt. The first connecting member 11 and the second connecting member 12 can also use other components with connection functions as needed. The backpack body 1 is provided with a backpack strap 13.

[0019] When the utility model is in use, the backpack body 1 is fixed to the carrier through the backpack strap 13, the mobile power supply 4 provides power support to the fan, the fan contacts the carrier's body, separates the backpack body 1 from the carrier, and then starts the fan motor 7 to drive the fan blades 8 to rotate, so that air flows, accelerates the heat dissipation of the backpack and the carrier's body, lowers the temperature, reduces the sweating of the carrier's body, thereby reducing the stain and odor of the backpack fabric, and also makes the backpack carrier feel cool and comfortable.

[0020] The fan of the utility model can be provided with a separate control switch, or the control switch of the mobile power supply 4 can be directly used to control the connection or disconnection of the circuit. The first ventilation hole provided on the ventilation plate 2 is convenient for the backpack body 1 to dissipate heat; the second ventilation holes provided on the bottom plate 5 and the connecting plate 10, and the distance provided between the ventilation plate 2 and the connecting plate 10 are convenient for air flow. When the weather temperature is not high, the ventilation plate 2 and the fan can be removed to reduce the burden of carrying.
