Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, and in particular to a waist-mounted fan. Background Technology

[0002] In hot weather, people use air conditioners, fans, and other devices to cool down, especially in summer when cooling is essential. However, traditional cooling devices of this kind require electricity, so they are generally only suitable for indoor use and cannot be carried around. When people are outdoors or resting in the open air, they can only rely on fans or natural wind to cool themselves down, which is not only inconvenient to use but also quite tiring. With the development of society, various portable electric fans have appeared on the market, such as neck fans and waist fans.

[0003] Existing waist-hanging fans have the following problems: They can only be hung around the waist via a hanging structure, and due to the lack of support, they cannot be placed on a table for operation when the user is sitting or resting. Additionally, existing waist-hanging fans can only be hung on one side, making it impossible to wear or secure them in either direction. Utility Model Content

The support arm is installed in the U-shaped storage groove. One end of the support arm is rotatably connected to the first clamping arm and / or the second clamping arm through a movable part, and the surface of the other end is slightly raised to form a buckle groove.

[0008] As a further improvement of this application, the fan body includes a duct that runs vertically through the protective housing, with the upper end of the duct being an air outlet and the lower end being an air inlet.

[0009] As a further improvement of this application, a hollow fixing seat is provided inside the air duct and near the air outlet, and a light-emitting body is installed on the hollow fixing seat.

[0010] As a further improvement of this application, the fan body also includes a concentrator nozzle that is detachably connected to the air outlet, the concentrator nozzle being a conical structure with one end larger than the other.

[0011] As a further improvement of this application, the air inlet of the fan body is provided with the air inlet, the air inlet is disposed opposite to the air concentrator, and the air inlet and the air concentrator are adapted to each other.

[0012] As a further improvement to this application, the inflation nozzle is equipped with an air inlet cover.

[0013] As a further improvement of this application, the fan body is also provided with a drive motor, a battery and a circuit board, and the battery and drive motor are connected to the circuit board.

[0014] As a further improvement of this application, the circuit board is provided with a charging connector, and the fan body is provided with a charging female socket at the corresponding position of the charging connector.
