[0004] In order to achieve the above-mentioned purpose, the utility model provides a portable fan with telescopic pull cord, which comprises a fan main body and a telescopic device arranged on the fan main body, the telescopic device comprises a hanging buckle, a rope body connected with the hanging buckle and a hovering positioning mechanism arranged in the fan main body, one end of the rope body away from the hanging buckle is connected with the hovering positioning mechanism, when the user pulls the hanging buckle, the rope body is stretched to the required length and then locked in position through the hovering positioning mechanism, the user pulls the hanging buckle again, and the hovering positioning mechanism releases the rope body, and the rope body automatically returns to the initial position.

[0005] The fan main body can be conveniently hung on a backpack, a shoulder bag and other personal items through the hanging buckle, without occupying the internal space of the backpack, so that the carrying is more convenient. When the fan is needed to be used, the user only needs to simply pull the hanging buckle, and the rope body will be smoothly pulled out from the inside of the fan main body, and the fan quickly changes from the storage state to the use state, so that the fan can be used at any angle without complex operation or assembly process. After use, the user pulls the hanging buckle again, and the rope is automatically wound back into the inside of the fan main body through the hovering positioning mechanism, so that the fan is quickly stored.

[0006] The fan main body comprises a front shell and a rear shell, a limiting protrusion is arranged on the front shell, and the rear shell is mounted on the front shell through the limiting protrusion; an installation groove is formed in the rear shell, an installation cover body is further arranged on the installation groove, a positioning screw column is arranged on the edge of the installation groove, a limiting ring matched with the positioning screw column is arranged on the edge of the installation cover body, a through hole through which an external screw passes is arranged on the limiting ring, and the limiting ring on the edge of the installation cover body and the positioning screw column on the edge of the installation groove are screwed and covered through the external screw to form a containing cavity, wherein the containing cavity is used for containing the hovering positioning mechanism.

[0007] The front shell and the rear shell are tightly connected through the limiting protrusions, which ensures that the fan body is compact and stable in structure. The arrangement of the limiting protrusions not only simplifies the assembly process, but also improves the overall stability and prevents loosening or misalignment during use. The design of the mounting groove and the mounting cover enables the hovering positioning mechanism to be effectively packaged in the accommodation cavity, protecting the hovering positioning mechanism from external environmental interference and achieving efficient use of the internal space of the fan body.

This design not only improves the convenience of fan use, but also ensures that the rope body can be reliably hovered at any position. The arrangement of the hovering unit enables the rope body to be quickly and accurately positioned when the pulling stops, avoiding free swinging or sliding of the rope body, thereby improving the user's experience.

[0010] The mounting groove and the mounting cover that covers the mounting groove together form a raised ring, and a wire passing hole is formed in the middle of the raised ring. The rope body moves between the wire reel and the carabiner through the wire passing hole of the raised ring. The portable fan also includes a wire protection sleeve, and the inner wall of the raised ring is provided with a clamping block. The wire protection sleeve is installed in the raised ring through the clamping block, and the wire protection sleeve is used to prevent the rope body from being worn out by reciprocating pulling.

[0011] The design of the wire protection sleeve effectively prevents the rope body from directly contacting the raised ring during reciprocating pulling, thereby reducing the wear of the rope body. This design not only prolongs the service life of the rope body, but also improves the reliability and durability of the fan. The clamping block provided on the inner wall of the raised ring provides a stable installation position for the wire protection sleeve, which ensures that the wire protection sleeve can be firmly installed in the raised ring and prevents the wire protection sleeve from falling off or shifting during use.

[0012] The rear shell is also provided with an avoidance hole, and the rope body moves between the wire reel and the carabiner through the avoidance hole. An annular groove is formed on the outer side of the rear shell for accommodating the carabiner, and the annular groove on the outer side of the rear shell is used to fix and accommodate the carabiner on the rear shell.

[0013] The annular groove opened on the outer side of the shell provides a fixed storage position for the hook. When the hook is not needed, the user can easily fix it in the annular groove, avoiding the problem of loss or damage caused by random placement. The design of the avoidance hole and the annular groove enables the user to enjoy a more convenient and comfortable operation experience when using the fan. The smooth movement of the rope and the convenient storage of the hook both improve the practicality and portability of the fan.

[0014] The hook comprises a body, a circular ring part rotatably arranged on the body, the circular ring part comprising a first arc-shaped part and a first pressing part used in cooperation with the first arc-shaped part, the first pressing part being rotatably arranged on the first arc-shaped part, when a user presses the first pressing part, the free end face of the first pressing part is away from the free end face of the first arc-shaped part, and when the user releases the first pressing part, the free end face of the first pressing part is in contact with the free end face of the first arc-shaped part to form a closed annular ring.

[0015] The circular ring part comprises a first arc-shaped part and a first pressing part used in cooperation with the first arc-shaped part. The user only needs to simply press the first pressing part to make the free end face of the first pressing part away from the free end face of the first arc-shaped part, so as to easily open the hook and hang the hook on personal articles. After releasing the first pressing part, the free end face of the first pressing part is in contact with the free end face of the first arc-shaped part to form a closed annular ring, ensuring the stability of the hook.

[0016] The portable fan further comprises a switch button arranged on the rear shell, an electric control board arranged inside the fan body, and a battery assembly, the battery assembly and the switch button being electrically connected with the electric control board.

[0017] The user can send an opening or closing instruction to the electric control board by pressing the switch button on the rear shell of the portable fan, the electric control board controls the power supply of the fan motor accordingly to realize the start and stop of the fan, and the battery assembly provides stable power for the electric control board and the motor in the whole process to ensure the continuous and stable work of the fan.

[0018] The portable fan further comprises a shell cover and a rotating assembly, the shell cover being mounted on the side of the front shell away from the rear shell via fasteners, and the shell cover being used for covering the rotating assembly. The design of the shell cover completely covers the internal rotating assembly (such as fan blades and motor) to prevent the user from directly contacting these high-speed rotating or electrified parts during use, thereby avoiding potential safety hazards.

[0019] The rotating assembly comprises a rotating wheel and fan blades arranged on the rotating wheel, the electric control board drives the rotating wheel to rotate, and the rotating wheel drives the fan blades arranged thereon to rotate to generate airflow; the fan surface of the fan blades gradually increases from the end close to the rotating wheel to the end away from the rotating wheel.

[0020] The rotating assembly is composed of a rotating wheel and fan blades arranged on the rotating wheel. When the electric control board drives the rotating wheel to rotate, the fan blades rotate accordingly, thereby generating air flow. This design ensures that the fan can efficiently generate air flow to achieve the effect of cooling. The fan surface of the fan blade gradually increases from the end close to the rotating wheel to the end away from the rotating wheel. This shape optimization helps to increase the sweeping area of the fan blade and improve the strength and coverage of the air flow. At the same time, the gradually increasing fan surface can also reduce the resistance of air flow, making the air flow smoother.

When the user pulls the rope body, the wire reel rotates to tighten the coil spring element. When the rope body is pulled to the maximum, the coil spring element changes from the tightened state to the relaxed state, driving the wire reel to rotate to realize the winding function.

[0024] The hovering unit further includes a guide device, the inner surface of the front shell body being provided with a recess, the guide device being arranged in the recess, and the guide device reciprocating along the length direction of the recess. The guide device is provided with a guide head, the guide device being in an I-shaped structure, and the guide head being in a columnar structure and arranged in the middle of the I-shaped structure.

[0025] The wire reel is provided with a guide rail on the side away from the coil spring element, and the guide rail is provided with a limiting block. When the rope body is pulled and the wire reel rotates, the guide device moves in the guide rail on the wire reel. When the guide head on the guide device moves to the limiting block on the guide rail, the movement of the wire reel is restricted, thereby realizing the positioning of the rope body in suspension. When the rope body is pulled again, the guide head on the guide device will be pushed out from the limiting block. When the rope body is pulled to the end, the elastic potential energy of the coil spring element is released, the coil spring element changes from the tightened state to the relaxed state, driving the wire reel to rotate to realize the winding function.

[0026] The hovering unit realizes the stretching, suspension positioning and recycling functions of the rope body through the cooperation of the coil spring member and the guide device. The design not only improves the convenience of the rope body, but also ensures the stability and reliability of the rope body in the recycling process.
