Description

Hair drier

Technical Field

The utility model relates to the field of blowers, in particular to a blower.

Background

Existing high speed blowers typically have an air inlet and an air outlet. The air inlet is positioned at the bottom or side of the body for introducing external air. The inside of the device is provided with a powerful motor and fan system. The motor is responsible for driving the fan to rotate, produces powerful air current, and the air outlet is located the hair-dryer front end for with the air current that handles through motor and fan discharge. A commercially available high-speed blower has a hollow design in the center of its housing, and the main reason for this hollow design is to provide a stronger and more concentrated air flow by using the aerodynamic principle, and the hollow design can generate a negative pressure effect by the high-speed and high-pressure air flow. When the air flow is sprayed out from the air outlet, the air at the outer side and the middle part can be driven to flow due to negative pressure generated by high speed and high pressure. This negative pressure effect may superimpose the air flows in the outer and middle portions together, creating a stronger air flow. So as to realize quick and effective blow-drying effect. Meanwhile, the hollow design can increase the air flow speed, so that the air flow is stronger. When the air flow passes through the hollow cavity, the air is accelerated, and the accelerated air flow has larger kinetic energy; in addition, through designing hollow shape and structure, can make the air current more concentrate in air outlet department, reduce the loss to improve and weather the effect. Therefore, many long-hair people find that the hair to be dried is penetrated into the hollow position of the blower, and the hair is dried by mixing the fresh air outside brought by the hollow design with the high-speed air flow in the middle, and meanwhile, the hair is dried and shaped more easily.

However, such hollow design hair dryers, while helping the user to dry the hair quickly and effectively, have drawbacks in that the hair is threaded into the hollow at the air outlet in a thread-by-thread manner. Firstly, time and labor are wasted: the hair is penetrated into the air at the air outlet part in a thread-by-thread manner, so that not only is the longer time needed, but also the greater tolerance and endurance are needed. This mode of operation requires cumbersome hand movements in the hollow of the hair through the wind. The user needs to pull a strand of hair into the air and keep the hair near the air outlet so that the air flow can effectively dry the hair. This requires high hand-eye coordination and fine handling skills, which may make the entire blow-drying process more laborious. It may be inconvenient for a person who needs to quickly finish hair. Secondly, wet hair after shampooing may get entangled when penetrating into the hollow holes, especially when the hair is longer or thicker, which is more likely to occur. This not only increases the difficulty of operation, but also makes it easier to block and disperse the air flow in the hollow portion of the hair dryer, making it difficult for the wind of the hair dryer to uniformly act on all portions of the hair. This may result in some of the hair not being adequately dried, or in other areas being excessively dried, affecting the overall drying effect.

Accordingly, there is a need for further optimization and improvement in existing blowers.
