[0024] To further illustrate the various embodiments, the present invention provides accompanying drawings. These drawings are part of the disclosure of the present invention and are mainly used to illustrate the embodiments, and can be used in conjunction with the relevant descriptions in the specification to explain the operating principles of the embodiments. With reference to these drawings, those skilled in the art should be able to understand other possible implementations and the advantages of the present invention. The components in the drawings are not drawn to scale, and similar component symbols are generally used to represent similar components.

[0025] The present invention will now be further described in conjunction with the accompanying drawings and specific embodiments.

[0026] Reference Figures 1 to 4 This embodiment provides a folding chair with a fan (hereinafter referred to as a folding chair) suitable for hot outdoor environments such as camping, fishing, and watching sports events, and ensures that users can still enjoy a cool experience in hot outdoor environments.

[0027] like Figure 1 and Figure 2 As shown, the folding chair of this embodiment includes a foldable chair frame 1 and a chair fabric 2 disposed on the chair frame 1, and also includes a fan 3 disposed on the chair fabric 2. The chair fabric 2 includes a first fabric 211 and a second fabric 212 disposed in front and behind. A portion of the chair fabric 2 is disposed on the back tube of the chair frame 1 to form a backrest 21, and another portion of the chair fabric 2 is disposed on the seat tube of the chair frame 1 to form a seat 22. Figure 3 The first fabric 211 shown has multiple ventilation holes 213 connected to the air vents 32 of the fan 3 in the area corresponding to the backrest 21.

[0028] In this embodiment, as Figure 2 As shown, the fan 3 is mounted on the mounting hole 215 of the second fabric 212 near the seat 22 through a protective cover. The protective cover ensures that the fan blades of the fan 3 will not come into direct contact with the fabric and also prevents the user from being injured by the rotating fan blades.

[0029] The air inlet 31 of the fan 3 is exposed on the back side of the second fabric 212 away from the first fabric 211, so as to ensure that outside air is drawn into the fan 3 and blown out from the air outlet 32 ​​of the fan 3. Then, the air is blown towards the back of the user on the folding chair through each vent 213, so as to facilitate heat dissipation of the user's back and other contact parts.

[0030] Furthermore, when the folding chair is unfolded, the first fabric 211 and the second fabric 212 of the chair back 21 are stretched open by the chair frame 1 and together form a cavity 214. The air outlet 32 ​​of the fan 3 is located inside the cavity 214, and each air vent 213 is connected to the cavity 214.

[0031] By placing the fan 3 on the chair fabric 2, the airflow actively generated by the fan 3 is blown onto the user on the folding chair through the ventilation holes 213 of the first fabric 211, thereby ensuring that the user enjoys a continuous cool experience in the hot outdoor environment, thus avoiding the user feeling stuffy and uncomfortable, and also improving the practicality and comfort of the folding chair.

[0032] Of course, in other embodiments, the chair frame 1 can also be a fixed chair structure that cannot be folded. Furthermore, the fan 3 and ventilation holes 213 can also be arranged in the area where the seat 22 is located, thus enabling active heat dissipation for the corresponding parts of the user.

[0033] In addition, such as Figure 1 and Figure 2 As shown, a storage bag 5 is provided on the rear side of the second fabric 212. Inside the storage bag 5 is a power bank 4 for powering the fan 3, and the power bank 4 is fixed inside the storage bag 5 by a fixing structure. The storage bag 5 should be made of a thermally conductive fabric, typically a double-layer structure. Specifically, the outer layer is abrasion-resistant nylon or polyester fabric, providing basic strength and durability; the inner layer is composited with a thermally conductive metal layer (such as aluminum foil) or a highly thermally conductive graphene coating to quickly conduct the heat generated by the power bank 4 during operation to the outside air. To further enhance heat dissipation efficiency, the surface of the storage bag 5 in contact with the power bank 4 can be designed with a mesh breathable structure. This prevents the power bank 4 from accumulating excessive heat due to prolonged use, thus ensuring the safety of the power bank 4 and personal safety.

[0034] In this specific embodiment, such as Figure 4 As shown, an electrical connection cable (i.e., power cord) is provided between the fan 3 and the power bank 4, and a switch 6 for controlling the operation of the fan 3 is integrated on the electrical connection cable. The electrical connection cable is threaded through the interlayer between the first fabric 211 and the second fabric 212 to hide the electrical connection cable inside the chair back 21, further ensuring the overall aesthetics of the folding chair. Of course, the electrical connection cable can be wrapped with a flexible and wear-resistant material to ensure that it is not easily worn or broken during use. Moreover, the design length of the electrical connection cable also provides sufficient leeway when the folding chair is unfolded or folded, so it will not affect the stability of the overall structure.

[0035] In addition, the storage bag 5 is preferably a three-dimensional bag-shaped structure with three sides sealed and one side open. An opening is provided on the inner wall of the storage bag 5 near the second fabric 212, through which the power supply cable passes to connect to the fan 3. The edge of this opening should be bound or reinforced to prevent wear on the cable.

[0036] A manually controlled switch 6 is located approximately 10 to 20 centimeters from the output port of the power bank 4, near the electrical connection cable between the fan 3 and the power bank 4. The switch 6 can be housed within the storage bag 5 along with the power bank 4, or it can be exposed at the opening of the storage bag 5 for easy user operation. Preferably, the switch 6 is a push-button switch, connected in series to the power supply circuit of the fan 3 to control the start and stop of the fan 3. When the fan 3 and the power bank 4 form a circuit through the electrical connection cable, pressing the switch once starts the fan 3; pressing it again stops the fan 3. It should be understood that the above-described push-button switch is only a preferred embodiment. Without departing from the concept of this utility model, the switch can also adopt other structural forms that can achieve the same on / off function, and functions such as wind speed adjustment can be added according to actual usage needs.

[0037] The power bank fixing structure of this embodiment includes at least one compartment disposed inside the storage bag 5 to fix the power bank 4 inside the compartment. That is, there are one or more independent compartments inside the storage bag 5, whose shape and size are completely matched to the power bank 4. The opening of the compartment is located inside or above the storage bag 5, and the power bank 4 can be inserted and fitted into it in a specified direction. The compartment is fixed to the storage bag 5 with reinforced stitching around its perimeter, and the bottom of the compartment is connected to the storage bag 5 to form a stable holding space. This can effectively limit the movement or flipping of the power bank 4 inside the compartment.

[0038] The fixed structure can securely place the power bank 4 inside the storage bag 5 to prevent the power connection cable of the fan 3 from becoming loose or even falling off due to bumps or shaking in the outdoor environment, or the power bank 4 from falling out of the storage bag 5.

[0039] Of course, in other embodiments, the storage bag 5 can also be placed on the chair frame 1, and the corresponding power bank 4 and power connection cable can also be adjusted accordingly, which will not be described in detail here.

[0040] Alternatively, elastic bands or adjustable elastic cords can be used to secure the power bank 4. The elastic bands can be arranged in an "X" shape or horizontally inside the storage bag 5, pressing the power bank 4 down from above. The elastic cords can form a tightenable restraint structure through pre-drilled holes in the storage bag 5 wall, ensuring the user can adjust the tightness of the restraint according to the size of the power bank 4, keeping it snug against the storage bag 5 without displacement. Alternatively, a safety buckle and hanging hole can be used to secure the power bank 4 inside the storage bag 5. Specifically, a hanging hole is pre-drilled on the outer shell of the power bank 4, and a matching safety buckle is installed at a corresponding position inside the storage bag 5. When the user places the power bank 4 into the storage bag 5, they can manually lock the safety buckle and hanging hole, effectively preventing the power bank 4 from detaching from the storage bag 5 during high-vibration environments such as outdoor transport. In addition, the power bank 4 can be secured inside the storage bag 5 by assembling a zipper or Velcro flap at the opening of the bag 5, preventing the power bank 4 from accidentally slipping out during movement, while also ensuring the convenience of taking it out and putting it in.

[0041] Preferably, the second fabric 212 is an airtight fabric, which can prevent the air blown by the fan 3 from escaping behind the backrest 21 through the second fabric 212, thereby ensuring that the airflow generated by the fan 3 is concentrated and blown forward toward the user's back through the cavity 214 and the ventilation hole 213.

[0042] Although the present invention has been specifically shown and described in conjunction with preferred embodiments, those skilled in the art should understand that various changes in form and detail may be made to the present invention without departing from the spirit and scope of the present invention as defined in the appended claims, and all such changes shall be within the scope of protection of the present invention.
