Description

Blower based on wind-guiding turns to and realizes function of making an uproar falls Technical Field The utility model relates to the technical field of blowers, in particular to a blower for realizing a noise reduction function based on air guide steering. Background The electric hair drier is used as a multifunctional electric appliance, is widely applied to drying and shaping hair, plays an important role in the fields of laboratories, physiotherapy rooms, industrial production, artists and the like, and is used for local drying, heating, physiotherapy and the like. The traditional electric hair drier generally relies on a motor to drive a rotor to drive a fan blade to rotate, so that an air channel for sucking air from an air inlet and blowing the air out from an air outlet is constructed. However, the air inlet of the traditional electric hair drier is generally arranged at the tail part of the outer shell, and adopts a mode of unidirectional air inlet. The design has a plurality of defects, because the tail air inlet is extremely easy to be involved in the hair of a user if the design is too large, potential safety hazards exist, and the air inlet and the air outlet are extremely limited if only the design is dependent on a small Kong Jinfeng. In addition, once the inlet opening is blocked by cotton wool, textile and the like, the service life of the motor can be greatly reduced, the temperature, the air quantity and the stability of the air outlet are seriously influenced, larger noise is easily generated, and even internal parts can be burnt under extreme conditions, so that economic loss and safety risks are caused for a user. In order to overcome the above-mentioned drawbacks of the conventional hair dryer, a lateral air intake dryer has been developed, such as the chinese patent entitled "a dryer" in application number CN202420839163.8 and the chinese patent entitled "a lateral air intake hair dryer" in application number CN202321893270.0, in which a lateral air intake through hole (i.e. an air intake) is provided at the rear end of the dryer, so that air flow can enter the interior of the dryer from the side. The novel design solves the limitation of the traditional back air intake mode to a certain extent, such as avoiding hair involved risk, increasing potential air intake and the like. However, the design of the lateral air intake exposes a pronounced short plate in terms of noise control, the direction of noise propagation is not reasonably directed, and during use, the noise propagates directly towards the body, in particular the ear. Because the ear is extremely sensitive to sound, the noise transmission mode which is directly (or directly) oriented to the human body greatly amplifies the perception of the noise by the user and seriously interferes with the user experience. The problem of noise of the lateral air intake blower is particularly remarkable when the air intake blower is used in environments such as home night rest and office places which are extremely sensitive to noise. At present, noise reduction measures for a side air intake blower are mostly limited to adding sound absorbing materials into the blower or performing sound insulation treatment on a motor part of the blower. However, these approaches merely do a passive response after noise generation, failing to effectively intervene from the beginning of the air flow into the interior of the blower. Because the air flow direction and the noise propagation direction of the air inlet are not optimized, the noise trouble caused by lateral air inlet is difficult to radically solve all the time. Disclosure of utility model The utility model aims to overcome the defects of the prior art and provides a technical scheme capable of solving the problems. An air blower for realizing noise reduction function based on air guiding steering, comprising: The air blower comprises a blower body, wherein an air duct is arranged in the blower body along the axial direction of the blower body; The air inlet structure comprises an air inlet area arranged at the rear end of the blower body, and a lateral air inlet through hole communicated with the air duct is arranged on the air inlet area; The wind scooper is fixedly connected or detachably connected to the rear end of the blower body and is used for guiding and converting radial airflow entering the lateral air inlet through hole and/or radial airflow approaching to the radial airflow into axial airflow along the axial direction of the blower body so as to change the noise direction of the air inlet area. The air guide cover is arranged on the outer side of the air inlet area in a surrounding mode and is matched with the air inlet area in an interval mode, and therefore an air inlet channel extending along the axial direction of the blower body is formed between the air guide cover and the air inlet area in a surrounding mode. As a further scheme of the utility model, the air guide cover and
