Description

Hand-held electric hair drier

Technical Field

The present invention relates to the field of hand-held household appliances, in particular to a hand-held hair dryer for hair care and for example hair dryers and heat-setting brushes.

Background

Based on the characteristic that the hair dryer can be rapidly shaped and dried, the hair dryer has a large audience group. The fan unit in the blower can suck air flow from an air inlet of the blower and send the sucked air flow out from an air outlet opposite to the air inlet, so that the drying purpose is achieved. Additionally, hot air blowers (such as heat styling brushes) are used to style hair in either a wet or dry condition. The air outlet of the blower can be connected with an air nozzle, the air speed of the air flow can be improved through the air nozzle, the air flow can be concentrated, and the purpose of modeling is achieved.

In a conventional heat setting apparatus, air is drawn into an inlet by a fan unit and is directed toward hair by an outlet. Often, a single appliance is provided with different accessories, each having a different outlet, and thus different functions, such as drying hair, curling hair, or volumizing. Depending on the desired hairstyle, the hair may be heated or unheated. The attachment may comprise bristles to which hair is wound and held for styling. Thus, the motor of a hair dryer is susceptible to damage from foreign objects such as dirt or hair, and a filter is therefore typically provided at the fluid inlet end of the hair dryer. A filter is provided to filter fluid entering the appliance to remove dirt and hair. Typically such appliances are provided with a nozzle which can be attached to or detached from the appliance and which changes the shape and velocity of the fluid stream exiting the appliance. Such a nozzle can be used to converge the effluent of the appliance or to diffuse the effluent according to the needs of the user at that moment.

It is known to provide multi-layer filtration systems, such as grids having relatively large pores and internal filters having relatively small pores. Often, the grille can be removed to clean the internal filter, or even replace one layer of the filter in the event of damage. The grille may be friction mounted, woven, mechanically attached or snap fitted to the housing of the appliance. Typically, the appliance includes a cable, in proximity to the fluid inlet and the filter of the appliance, for providing electrical power. If the filter is removed for cleaning, it remains on the cable, while it is preferably removed from the cable.

Chinese patent CN210960774U by dysen company seeks to provide a hairdryer filter design that can be completely removed from the appliance for cleaning and replacement without damaging the filter. But this patent is used in conjunction with the proprietary product of the company dysen.
