The utility model also provides a blower 100, referring to fig. 1 to 5, the blower 100 includes a housing 10, a fixing sleeve 20, a blower and a limiting block 223, an air duct is formed in the housing 10, the housing 10 has an air inlet 121 and an air outlet 112 which are communicated with the air duct; the fixed sleeve 20 is connected to the inside of the casing 10 and located in the air duct, and at least one hollow layer 222a is arranged on the circumference of the fixed sleeve 20; the fan is embedded in the fixed sleeve 20; the limit block 223 is connected to the inner wall surface of the fixing sleeve 20 and covers the air duct, a plurality of vent holes 223a are formed in the limit block 223 at intervals, and the limit block 223 and the fixing sleeve 20 are of an integral structure.

Specifically, since the fan is in operation, the airflow easily drives the power line 30 in the housing 10 to move towards the fan, so that there is a certain danger, the inner wall of the fixing sleeve 20 is connected with the limiting block 223, and the limiting block 223 covers the air duct, so that the parts such as the power line 30 can be effectively prevented from moving towards the fan under the driving of the airflow, in an embodiment of the present application, the ventilation hole 223a can be a through hole of a regular hexagon, so that the plurality of holes of the regular hexagon can also function to adjust the airflow in the air duct, so that the airflow passing through the air duct is distributed more uniformly, so as to avoid the occurrence of high-frequency noise caused by non-uniform airflow direction distribution, and the limiting block 223 is arranged in the fixing sleeve 20 and integrated with the fixing sleeve 20, so that the installation process is not only omitted, meanwhile, no extra gap is formed between the limiting block 223 and the fixing sleeve 20, so that the air flow in the air duct can only pass through the vent holes, the air flow in the air duct is ensured to be uniformly distributed, the generation of high-frequency noise is reduced, the noise of the hair drier 100 in use is reduced, and the usability of the hair drier 100 is improved. It should be noted that the vent hole 223a may also be other regular openings such as a round hole, which may be selected by those skilled in the art and will not be described herein.

The above only is the preferred embodiment of the present invention, not limiting the scope of the present invention, all the equivalent structure changes made by the contents of the specification and the drawings under the inventive concept of the present invention, or the direct/indirect application in other related technical fields are included in the patent protection scope of the present invention.
