Description

Technical Field

[0001] This utility model relates to a fan, and more particularly to a portable rechargeable fan. Background Technology

[0002] Portable rechargeable fans have gradually become a common cooling tool for outdoor activities, home use, and travel due to their portability and lack of external power supply. However, mosquito bites often bother users when using fans in summer, especially in outdoor environments. Traditional outdoor mosquito repellent methods, such as mosquito repellent sprays and bracelets, usually need to be carried and used separately, increasing the burden of travel.

[0003] While some portable fans on the market combine lighting and spraying functions, their design for mosquito repellency is still relatively limited. Some products attempt to integrate mosquito repellent sheets or liquids into the fan, but these solutions have the following problems: (1) The structure is relatively complex, and the mosquito repellent module is fixedly integrated with the fan body, which increases the size of the product and makes disassembly and assembly inconvenient; (2) The mosquito repellent function cannot be flexibly activated or deactivated according to user needs. If independent control is required, the design of the fan control module is relatively complex, resulting in higher manufacturing costs; (3) Mosquito repellent components, such as liquid tanks or chips, need to be replaced frequently, which requires frequent disassembly and assembly of the fan body. Improper disassembly and assembly can easily damage the fan and shorten its service life. Summary of the Invention

[0004] The technical problem to be solved by this utility model is to provide a portable rechargeable fan that is simple in structure, has mosquito repellent function, and is flexible in use.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A portable rechargeable fan includes a fan body with an air outlet. A mosquito-repelling ring with a mosquito-repelling function is detachably disposed on the fan body, the mosquito-repelling ring surrounding the air outlet and the air outlet being located within the mosquito-repelling ring.

[0007] The fan body includes a main body and a mosquito repellent ring mounting part. The air outlet is located on the front end face of the mosquito repellent ring mounting part. The mosquito repellent ring is made of a flexible material that can undergo elastic deformation. The mosquito repellent ring is tightly fitted and mounted on the mosquito repellent ring mounting part.

[0008] The side end face of the mosquito repellent ring mounting part is provided with a protruding anti-detachment positioning rib.

[0009] The main body and the mosquito repellent ring mounting part are coaxially arranged. The size of the mosquito repellent ring mounting part is smaller than the size of the main body, so that the front end face of the main body forms a limiting step surface for limiting the installation position of the mosquito repellent ring.

[0010] The fan body is provided with a bracket, which includes a support base and a flexible arm that can be freely bent and twisted. The flexible arm is connected between the support base and the fan body.

[0011] The bottom of the support base is detachably connected to at least three flexible winding arms that can freely bend and twist.

[0012] The bottom of the flexible winding arm is equipped with a suction cup.

[0013] The flexible winding arm has multiple annular recesses spaced apart along the axial direction of the arm body, so that convex parts are formed between adjacent recesses.

[0014] The tops of the multiple flexible winding arms are connected by a connecting seat, which is detachably connected to the support base.

[0015] The connecting seat is provided with a connecting post with external threads, and the bottom of the support base is provided with a connecting cavity with internal threads that mates with the connecting post. The connecting seat is screwed to the support base.

[0016] Both the flexible arm and the flexible winding arm are made of metal wire wrapped with soft silicone.

[0017] Compared with existing technologies, the advantages of this utility model are as follows: It has a simple structure, integrating a detachable mosquito-repellent ring onto the fan body, combining the mosquito-repellent function with the fan function. This eliminates the need to carry additional mosquito repellent liquid, mosquito-repellent bracelets, or other equipment, reducing travel burden and improving the convenience of outdoor use. The mosquito-repellent ring is detachably installed on the fan body, allowing users to flexibly install or remove the mosquito-repellent function as needed without complicated operations. Replacing the mosquito-repellent ring is also convenient, avoiding the difficulties in disassembling and assembling traditional integrated mosquito-repellent fans, while reducing the risk of fan damage due to misoperation. The mosquito-repellent ring surrounds the air outlet, occupying no extra space and not significantly increasing the fan's size or weight, maintaining the lightweight characteristics of a portable fan without affecting the airflow effect. Furthermore, when the fan is running, the mosquito-repellent ingredients on the ring diffuse with the airflow, increasing the mosquito-repellent range and improving mosquito-repellent efficiency, making it particularly suitable for outdoor scenarios.

[0023] Figure 6 This is an exploded structural diagram of Embodiment 2 of the present invention. Detailed Implementation

[0024] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0025] Example 1: As shown in the figure, a portable rechargeable fan includes a fan body 1, the fan body 1 has an air outlet 10, and a mosquito repellent ring 2 with a mosquito repellent function is detachably provided on the fan body 1. The mosquito repellent ring 2 surrounds the air outlet 10, and the air outlet 10 is located inside the mosquito repellent ring 2.

[0026] In this specific embodiment, the fan body 1 includes a main body 101 and a mosquito repellent ring mounting part 102. The air outlet 10 is disposed on the front end face of the mosquito repellent ring mounting part 102. The mosquito repellent ring 2 is made of a flexible material that can undergo elastic deformation and is tightly fitted onto the mosquito repellent ring mounting part 102. The mosquito repellent ring 2 is made of a flexible material that can undergo elastic deformation, which ensures that the mosquito repellent ring 2 fits tightly with the mosquito repellent ring mounting part 102, preventing loosening or falling off. No additional fasteners are needed, and users can easily install or remove the mosquito repellent ring 2 by hand, making maintenance and replacement more convenient. Moreover, the flexible material can adapt to slight dimensional deviations, improving compatibility with fans of different specifications.

[0027] In this specific embodiment, the mosquito repellent ring 2 is made of soft silicone material. Soft silicone has excellent elastic recovery ability.

[0028] In this specific embodiment, a detachment-prevention positioning rib 11 is raised on the side end face of the mosquito repellent ring mounting part 102.

The flexible arm 302 can be freely bent and twisted, allowing users to easily adjust the airflow direction of the fan to meet the usage needs of different scenarios.

[0031] In Embodiment 2, the rest is the same as in Embodiment 1, except that at least three flexible wrapping arms 4, which can freely bend and twist, are detachably connected to the bottom of the support base 301. The flexible wrapping arms 4 provide a wrapping installation function, making it suitable for more scenarios, such as wrapping and installing in strollers, cars, or tents.

[0032] In this specific embodiment, a suction cup 5 is provided at the bottom of the flexible arm 4. The suction cup 5 can adhere to smooth surfaces such as glass and tabletops, enhancing stability and preventing the fan from sliding or tipping over. Combined with the upright position of the flexible arm 4, the entire unit can be used on a stable surface with a certain height.

[0033] In this specific embodiment, the flexible winding arm 4 has multiple annular recesses 41 spaced apart along the axial direction of the arm body, forming protrusions 42 between adjacent recesses 41. The recesses 41 and protrusions 42 form an anti-slip texture, making it easier to fix and less likely to loosen during winding.

[0034] In this specific embodiment, the tops of multiple flexible winding arms 4 are connected by a connecting seat 6, which is detachably connected to the support base 301. This allows the multiple flexible winding arms 4 to form an integral structure, making overall installation and disassembly convenient. Furthermore, the connecting seat 6 ensures that the winding arms are subjected to uniform force, preventing localized loosening.

[0035] In this specific embodiment, the connecting seat 6 is provided with a connecting post 61 with external threads, and the bottom of the support base 301 is provided with a connecting cavity 300 with internal threads that mates with the connecting post 61. The connecting seat 6 and the support base 301 are screwed together. The structure is simple, the connection and installation are stable, and the installation and disassembly are convenient and the cost is low.

[0036] In this specific embodiment, both the flexible arm 302 and the flexible winding arm 4 are made of metal wire wrapped with soft silicone.
