Abstract

The invention discloses a portable fan with the adjustable vertical angle. The portable fan comprises a front cover and a rear cover. Locking screws are fixed to the periphery of the surface of the front cover. A shaft core is arranged in the middle of the front cover. The outer side of the shaft core is provided with a shaft sleeve. Fan blades are arranged on the surface of the shaft sleeve. Rotation shafts are fixed to the right side wall of the front cover. Clamping bases are arranged on the outer sides of the rotation shafts. First screws are arranged in the rotation shafts. A base is connected to the lower portions of the clamping bases. A telescopic handle is fixed to the lower portion of the base. A protection hood is arranged in front of the front cover. A motor is arranged in themiddle of the rear cover, the rear cover is located behind the front cover, a damping frame is arranged on the right side of the motor, and a heat dissipation plate is arranged between the shaft coreand the shaft sleeve. The portable fan is provided with the rotation shafts, the size of the rotation shafts coincides with the size of the clamping bases, the rotation shafts can drive the clamping bases to rotate, the clamping bases and the rotation shafts are mutually fixed through the first screws, and the vertical angle of the fan is convenient to adjust.

Description

technical field [0001] The invention relates to the technical field of fan equipment, in particular to a portable fan whose vertical angle can be adjusted. Background technique [0002] With the rapid development of economy and the advancement of science and technology in various regions, the fan has been invented for more than one hundred years in the world, and it is a necessary item in the hot summer. However, with the advancement of science and technology, the invention of high-end nodes such as air conditioners and The application has gradually started to go downhill. From the perspective of energy saving and aspects, electric fans have certain advantages, and air conditioners can only be used indoors. Therefore, in order to restore the fan market, portable fans have begun to appear, which can be carried and outdoors to cool off the heat. , as the environment changes, the temperature in summer is getting higher and higher, so portable fans are favored in the commodity m...
