DETAILED DESCRIPTION

[0024] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0025] like Figures 1 to 4 As shown, Figure 1 This is a three-dimensional structural diagram of a fan according to an embodiment of the present invention. Figure 2 This is another three-dimensional structural schematic diagram of a fan according to an embodiment of the utility model. Figure 3 This is a cross-sectional schematic diagram of a fan according to an embodiment of the present invention. Figure 4 The schematic cross-sectional view of the air duct of a fan according to an embodiment of the present invention is shown in FIG. 1 . The present invention provides a fan according to an embodiment of the present invention, and the fan comprises a fan body 100 , a connecting member 200 and a heat dissipation assembly 120 . The fan body 100 is provided with an air inlet 150 and an air outlet 140 .

[0026] The connecting member 200 is disposed on the first side of the fan body 100 and can be used to be detachably connected to a backpack. The user can detachably connect the fan to the back of any backpack through the connecting member 200 as needed, and the assembly and disassembly methods are simple, wherein the back of the backpack refers to the side of the backpack that contacts the user when the user carries the backpack. Since the fan is installed on the back of the backpack, when the user carries the backpack, the contact area between the user's back and the back of the backpack is reduced, and an air flow space can be formed, which helps to dissipate heat from the user's back.

[0027] The heat dissipation assembly 120 is at least partially disposed in the fan body 100. The air inlet 150, the heat dissipation assembly 120 and the air outlet 140 form an air duct. When the heat dissipation assembly 120 is in operation, air outside the fan body 100 enters from the air inlet 150, passes through the heat dissipation assembly 120, and then is discharged from the air outlet 140, forming an air flow. The air flow can effectively ventilate and dissipate heat for the user's back.

[0028] The fan provided in the embodiment of the utility model can realize detachable connection between the fan and the back of various types of backpacks through the connecting piece 200, and the assembly and disassembly methods are simple. Moreover, the fan can be adapted to various types of backpacks and has high versatility. When a user carries various types of backpacks, the fan can generate airflow on the back of the user, thereby realizing effective ventilation and heat dissipation of the back of the user, and improving the comfort of the user when carrying the backpack.

[0029] In one embodiment, the side of the connecting member 200 close to the fan body 100 is connected to the fan body 100, and the other side of the connecting member 200 away from the fan body 100 is provided with an adhesive member. The connecting member 200 and the fan body 100 can be fixedly connected. The connecting member 200 and the fan body 100 can also be detachably connected, for example, by snap-fitting, pasting, etc. The adhesive member provided on the other side of the connecting member 200 away from the fan body 100 can be used to achieve a detachable connection between the fan and the backpack.

[0030] The adhesive member includes at least one of double-sided tape, cloth tape, nano tape, etc. The adhesive member can ensure that the fan body 100 can be firmly fixed on the back of different types of backpacks, that is, it can be adapted to different types of backpacks, and the fan body 100 can be easily removed from the back of the backpack, so that the user can use it flexibly according to needs. In a specific embodiment, the adhesive member can have a certain thickness so that it can be better attached to the back of the backpack with a mesh support structure.

[0031] In one embodiment, the heat dissipation assembly 120 includes a motor 121 and a fan blade 122. Figure 3 As shown, the air inlet 150, the motor 121, the fan blades 122 and the air outlet 140 are arranged in sequence in a first direction, wherein the first direction is the height direction of the fan body 100. The first direction is also the direction of the air duct axis. When the fan is mounted on the back of the backpack, the first direction is roughly parallel to the back of the backpack. The motor 121 and the fan blades 122 are electrically connected. When the motor 121 is powered, the motor 121 drives the fan blades 122 to rotate, and the air outside the fan body 100 enters from the air inlet 150 and then is discharged from the air outlet 140, forming an airflow flow, thereby generating wind force.

[0032] The air inlet 150, the motor 121, the fan blades 122 and the air outlet 140 are sequentially arranged in the height direction of the fan body 100 to form an air duct along the height direction of the fan body 100. Compared with the air duct being arranged along the thickness direction of the fan body 100, the thickness of the fan body 100 can be effectively reduced, so that when the fan is mounted on the back of the backpack, it will not cause discomfort to the back of the user. The air inlet 150, the motor 121, the fan blades 122 and the air outlet 140 are arranged in the same direction, and the air duct structure formed is simple, and the air duct is linear, with minimal wind resistance, which can effectively reduce the energy consumption of the heat dissipation component 120.

[0033] In one embodiment, the air outlet 140 and the air inlet 150 are respectively arranged on the second side and the third side of the fan body 100 that are opposite in the first direction. When the user assembles the fan to the backpack, the user can select the assembly direction of the fan as needed, thereby selecting the air outlet 140 at the top and the air inlet 150 at the bottom, or selecting the air outlet 140 at the bottom and the air inlet 150 at the top to form different airflow directions. If the user needs the airflow direction from bottom to top, so that the air outlet direction of the fan is toward the upper part of the user's back, when the fan is assembled to the backpack, the assembly direction of the air outlet 140 at the top and the air inlet 150 at the bottom is adopted; if the user needs the airflow direction from top to bottom, so that the air outlet direction of the fan is toward the lower part of the user's back, when the fan is assembled to the backpack, the assembly direction of the air outlet 140 at the bottom and the air inlet 150 at the top is adopted. In this way, the user can freely and conveniently select the airflow direction of the fan.

[0034] like Figure 4 As shown, in one embodiment, the fan body 100 further includes at least two air outlet baffles disposed at the air outlet 140. The at least two air outlet baffles are arranged along the thickness direction of the fan body 100, wherein the thickness direction of the fan body 100 is perpendicular to the first side surface. The at least two air outlet baffles are tilted toward a direction away from the connecting member 200. The at least two air outlet baffles are at a preset angle to the first direction, so that when the fan is fixed to the backpack through the connecting member 200, the air outlet direction of the air duct is toward a direction away from the backpack.

[0035] When the air inlet 150, the motor 121, the fan blades 122 and the air outlet 140 are arranged along the height direction of the fan body 100 to form a linear air duct, the air duct has a simple structure and minimizes wind resistance, which can effectively reduce the energy consumption of the heat dissipation component 120; at least two air outlet baffles are arranged to be inclined in the direction away from the connecting member 200, and can form an air outlet direction close to the horizontal direction on the basis of maintaining the linear air duct, so that when the fan is assembled in the air outlet direction, the air outlet direction is away from the backpack and towards the user's back, thereby effectively ventilating and cooling the user's back and reducing the temperature of the user's back.

[0036] In one embodiment, the preset angles of at least two air outlet baffles with the first direction gradually increase in the direction away from the connector 200. This design can effectively guide the wind output from the air outlet 140 to blow toward the back of the user, thereby improving the heat dissipation and cooling effect.

[0037] In a specific embodiment, the fan body 100 includes a first air outlet baffle 141, a second air outlet baffle 142, a third air outlet baffle 143, a fourth air outlet baffle 144 and a fifth air outlet baffle 145 arranged in sequence along the thickness direction of the fan body 100, wherein the first air outlet baffle 141 is closest to the first side surface. The preset angles of the five air outlet baffles to the first direction gradually increase. For example, the preset angle of the first air outlet baffle 141 to the first direction is 45 degrees, the preset angle of the second air outlet baffle 142 to the first direction is 55 degrees, the preset angle of the third air outlet baffle 143 to the first direction is 65 degrees, the preset angle of the fourth air outlet baffle 144 to the first direction is 75 degrees, and the preset angle of the fifth air outlet baffle 145 to the first direction is 85 degrees. It is understandable that the fan body 100 may include two or more air outlet baffles, and the preset angle between each air outlet baffle and the first direction may be set as required, which is not limited here.

[0038] In one embodiment, the heat dissipation assembly 120 includes at least two heat dissipation subassemblies arranged side by side in a second direction, wherein the second direction is the length direction of the fan body 100. When the fan is installed on the back of a backpack, the second direction is roughly parallel to the back of the backpack. Each of the at least two heat dissipation subassemblies includes a motor 121 and a fan blade 122. The air outlet 140 includes at least two sub-air outlets corresponding to the at least two heat dissipation subassemblies. When the fan is installed on the back of the backpack, a gap is generated between the back of the backpack and the back of the user, causing the center of gravity of the force to move backward, which may affect the force applied by the backpack on the user and cause discomfort to the shoulders of the user carrying the backpack. In order to reduce this discomfort, it is necessary to minimize the thickness of the fan body 100, that is, it is necessary to minimize the size of the fan blades 122 of the heat dissipation assembly 120. Since the reduction in the size of the fan blades 122 will reduce the wind force, in order to increase the wind output, two or more motors 121 and fan blades 122 are arranged side by side in the length direction of the fan body 100, thereby reducing the thickness of the fan body 100 to reduce the discomfort caused by the fan to the user, but also increasing the wind output of the fan, thereby improving the ventilation and heat dissipation effect on the user's back.

[0039] In one embodiment, the fan further includes a power supply component electrically connected to the heat dissipation component 120 .

[0040] In a specific embodiment, the power supply assembly includes a first power cord 110, a first control assembly 112 and a power interface 111. One end of the first power cord 110 is connected to the fan body 100, and the other end of the first power cord 110 is connected to the power interface 111. The first control assembly 112 is arranged on the first power cord 110 and the first control assembly 112 is electrically connected to the first power cord 110. The power interface 111 is used to connect an external power supply. The power interface 111 is an interface that can be connected to an external power supply, such as a USB interface, a Type-C interface, etc., which is not limited here. The external power supply can be a mobile power supply, a battery pack, etc., which is not limited here. The first control assembly 112 is used to control the power on and off of the power cord. Further, the first control assembly 112 can also be used to control the power supply power or current of the external power supply, so as to adjust the speed of the fan blades 122, so as to adjust the output wind force of the fan. The first control assembly 112 can use a button or a touch key.

[0041] When the fan is fixed to the back of the backpack, the fan is located on the back of the user. In this embodiment, a first control component 112 is arranged on the first power cord 110 so that the first control component 112 can be located in an area that can be touched by the user's hand or in an area that can be seen by the human eye, so that the user can control the power on and off and the wind speed of the fan through the first control component 112.

[0042] This embodiment uses a method of connecting an external power supply to power the fan. When the first power line 110 is connected to the external power supply through the power interface 111, the first control component 112 can adjust the power or current input from the external power supply to the heat dissipation component 120, thereby adjusting the speed of the fan blades 122 of the heat dissipation component 120, thereby adjusting the output wind force. The external power supply can be a mobile power supply that can be placed in a backpack, thereby solving the problem of storing the external power supply.

[0043] In another specific embodiment, the power supply assembly includes a battery assembly, a second power line and a second control assembly. The battery assembly is connected to the heat dissipation assembly 120. One end of the second power line is connected to the battery assembly. The other end of the second power line is connected to the second control assembly. The battery assembly can be arranged inside the fan body 100, or arranged outside the fan body 100, or at least partially arranged inside the fan body 100. The second control assembly can be used for the power supply of the battery assembly, so as to adjust the rotation speed of the fan blades 122 to adjust the output wind force of the fan. The second control assembly can use a button or a touch key.

[0044] In this embodiment, a second control component is arranged on the second power cord so that the second control component can be located within the reachable area of ​​the user's hand or the visible area of ​​the human eye, so that the user can control the power on and off and the wind speed of the fan through the second control component.

[0045] In one embodiment, the power supply assembly further includes a retractable structure and a storage cavity, and the retractable structure is used to extend the first power cord 110 and / or the second power cord from the storage cavity or at least partially retract it into the storage cavity. This design is conducive to the storage of the power cord.

[0046] In one embodiment, the power supply assembly further includes a fixing member 113. The fixing member 113 is used to assist in fixing the first power cord 110 or the second power cord, for example, to fix the first power cord 110 or the second power cord in a side pocket of a backpack or the like.

[0047] In one embodiment, the fan further includes a buffer 300. The buffer 300 is disposed on a fourth side surface of the fan body 100 opposite to the first side surface. That is, the buffer 300 and the connector 200 are respectively disposed on two opposite sides of the fan body 100. The buffer 300 may be a flexible member, for example, the buffer 300 may be a protective buffer pad including EVA foam and mesh fabric. When the fan is assembled to the back of the backpack through the connector 200, the buffer 300 faces a direction away from the back of the backpack, so that when the user carries the backpack, the buffer 300 is located between the fan body 100 and the user's back, and as a buffer medium between the fan body 100 and the user's back, it can buffer the pressure exerted by the fan body 100 on the user's back, thereby improving the comfort of the user's back.

[0048] In one embodiment, the buffer 300 includes a buffer body and a storage portion 310, and the storage portion 310 is disposed on the buffer body. The storage portion 310 is used to store the first power cord 110 or the second power cord. In a specific embodiment, the storage portion 310 is a mesh bag structure or a semi-enclosed pocket structure, and the specific form of the storage portion 310 is not limited here.
