Problems solved by technology

This device consists of two motors placed one behind the other in the handle. The main disadvantage of such a device is that the passage of the air flow from the remote motor fan is blocked because of the location of the motor driving the brush.
In order to better respond to the need for mass balance, said devices always have the disadvantage that the use of brushes with large diameters is limited because on the one hand the blower wheel is arranged above the handle and on the other hand because of the safety cylinder surrounding the heating element large diameter of
Furthermore, the close arrangement of the heating element and the motor driving the brushes on the one hand complicates the electrical connection of each of them and on the other hand leads to the danger of heating the motor and thus reducing its service life
Furthermore, the protective sleeve is located outside the handle, and for reasons of standardization and safety, air can only escape through very thin slits of the protective sleeve, thus resulting in an uneven distribution of the blown air in the attachment, therefore, in Uneven distribution of the blown air in the treated hair strands

Abstract

The invention relates to an electrical hairbrush (1) including a longitudinal housing (2) defining a gripping handle (3), a heating member (5), a first motor (6) for driving a fan (7) for circulatingair from an air intake opening (9) located at one end of the handle towards an air outlet opening (10) located at the opposite end of the handle,and a second motor (14) for rotating a hairdressing accessory (11), characterised in that the fan (7), the first motor (6) and the heating member (5) are contained within the handle (3) and in that the second motor (14) is connected by at least one rod tothe outside of the handle (3) in the same direction thereof while being coaxial or parallel to the longitudinal axis of the handle, the base of the rod being attached to the handle (3) and having a front extension in the form of a holding portion for the second motor (14).

Description

technical field [0001] The invention relates to a device for styling hair, a device of this type comprising a brush driven in rotation in a holder arranged at the outlet of a box which blows a stream of hot air to effect the styling of the hair. Background technique [0002] Document US3890984 describes a hairdressing device comprising a box constituting the handle, in which is housed a first motor driving a fan which draws ambient air from one of the ends of the box, causing the ambient air to undergo heating element, which then sends ambient air into a reduced-diameter central tube that runs along the box and protrudes at the other end. Inside the box there is also a second motor, which is placed in parallel with said first motor, so as to ensure the rotational drive of the brush provided at the end of the box, while the brush is mounted to rotate around the tube conveying the air . While using the complex technical solution of driving and guiding the brushes in rotation...
