Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of hair dryers, and specifically relates to a high-speed hair dryer that prevents foreign objects from entering. Background Technique
[0002] Modern hair dryers are mechanical devices that accelerate the air flow speed in an electric manner, thus generating wind and simultaneously increasing the air temperature. Hair dryers are mainly used for drying and shaping hair, but can also be used for local drying, heating, and physiotherapy in laboratories, physiotherapy rooms, industrial production, art, etc. Although there are many types of hair dryers, their structures are basically the same, and they are all composed of a housing, a handle, a motor, a fan blade, a heating element, a wind deflector, a switch, a power cord, etc.
[0003] However, no matter what structure the hair dryer has, a layer of filter screen will be provided at the air inlet at one end. In the utility model with the Chinese patent publication number CN221244365U, a filter screen structure for a high-speed hair dryer is proposed to prevent foreign objects from entering the interior of the fan, thereby causing damage to the fan, and at the same time reducing dust and floating hair in the air from entering the interior of the fan. However, the general fan filter screen is just a simple layer of metal protection net. However, the hole pitch of the metal protection net in the prior art is still relatively large, the structure is relatively simple, and the filtering effect is not good. Therefore, a high-speed hair dryer that prevents foreign objects from entering is proposed here. Content of the Utility Model
