Description

Technical Field

[0001] This utility model relates to the field of fan technology, and in particular to a four-engine wearable fan that can be used for both neck and waist hanging. Background Technology

[0002] With frequent high temperatures and extreme weather events worldwide, the demand for outdoor cooling is growing. To meet users' needs for portable cooling in different scenarios, two types of wearable fans have emerged on the market: neck-mounted and waist-mounted.

[0003] The neck fan features an ergonomic U-shaped design that fits snugly around the neck. Its dual air outlets direct airflow to high-temperature sensitive areas such as the face, neck, and head, providing rapid, localized cooling. It's suitable for daily commutes and office work. The waist fan, on the other hand, is attached to the waist via an adjustable belt or clip. Its multi-directional air outlets target areas with high sweat gland density, such as the back and waist, making it ideal for activities like cycling and hiking.

[0004] However, existing neck-hanging or waist-hanging fans are completely independent structural designs, making it difficult to switch between usage modes and failing to meet users' diverse needs for portable cooling devices. Carrying two types of fans at the same time increases the burden of travel and reduces efficiency. Therefore, there is an urgent need for an integrated dual-mode fan that can not only adapt to neck-hanging mode but also switch to waist-hanging mode, thus adapting to diverse outdoor activity needs. Utility Model Content

[0005] To address the problems mentioned above, this invention provides a four-engine wearable fan that can be used for both neck and waist hanging. It can not only be used in neck hanging mode but also be converted to waist hanging mode, making it suitable for various outdoor activities.

[0006] The solution adopted by this utility model to solve its technical problem is: a four-engine wearable neck and waist dual-purpose fan, including a support part and an adjustment part hinged to both ends of the support part;

[0007] Both the support section and the adjustment section are equipped with airflow generators; both the support section and the adjustment section have air outlets on their top surfaces; and both the support section and the adjustment section have elastic buckles on the side facing the human body.

[0008] Furthermore, the airflow generator is equipped with a semiconductor condensation system.

[0009] Furthermore, the support portion has mounting cavities at both ends, and the adjustment portion also has a mounting cavity at the end away from the support portion, with the airflow generator fixed inside the mounting cavity.

[0010] Furthermore, the adjustable angle range of the adjustment part relative to the support part is 0° to 100°.

[0011] In summary, the beneficial effects of this utility model are as follows:

[0012] 1. The dual-purpose fan of this application has adjustable parts hinged on both sides of the support part. By rotating the adjustable parts, the fan body can be bent into a U-shaped neck or stretched into a straight waist hanger. At the same time, the elastic buckle on the support part can not only strengthen the neck support, but also be fastened to the waistband to fix it in the waist position.

[0013] 2. The airflow generator is equipped with a semiconductor condensation system, which can achieve efficient cooling and improve the heat dissipation effect of the fan;

[0014] 3. The dual-purpose fan of this application is equipped with four airflow generators, which are respectively installed in symmetrical positions on the support and adjustment parts. This can provide a large area of ​​airflow to meet the cooling needs of different parts. The even arrangement of the four airflow generators also makes the fan airflow more uniform.
