The terms "first," "second," "third," and the like in the description and in the claims of the present application, and in the drawings, if any, are used for distinguishing between similar elements and not necessarily for describing a particular sequential or chronological order. It is to be understood that the objects so described are interchangeable under appropriate circumstances. In the description of the present application, "a plurality" means two or more unless specifically limited otherwise. Furthermore, the terms "comprising" and "having," as well as any variations thereof, are intended to cover a non-exclusive inclusion. The directional phrases referred to in this application, for example: up, down, left, right, front, rear, inner, outer, lateral, etc., are simply directions with reference to the drawings.

As shown in fig. 5, the present invention provides an automatic electrical connection device for a high speed hair dryer accessory, comprising: body 41, negative ion contact PCB42, spring 43, magnet 44, contact 45, and screw 46. Wherein, the body 41 is used for fixing other components and can be matched and installed in the hollow channel 14 of the hair drier body 1; two contacts 45 are fixedly connected to the negative ion contact PCB42 and face one side of the body 41; the magnet 44 is also fixedly connected to the negative ion contact PCB42 and faces one side of the body 41, and is used for being mutually adsorbed with the magnetic attraction part 23 arranged inside the ion bar; the screw 46 passes through a through hole arranged on the negative ion contact PCB42 and then is fixed on the body 41, and meanwhile, the negative ion contact PCB42 can slide on the screw 46 in a straight line and is limited by the top of the screw 46 without falling off; the spring is in its natural state, the body 41 is at a distance, denoted d, from the negative ion contact PCB42₁And the length of the screw is denoted as d₂And the length of the contact is denoted as d₃Then d needs to be satisfied₂＞d₁＞d₃(ii) a The two contacts 45 and the two screws form four positioning points on the negative ion contact PCB42, and the spring 43 is positioned in the four positioning points by matching with the reserved space; two holes are formed on the body 41 corresponding to the two contacts 45 for the contacts to extend out.

As shown in fig. 6a-c and 7a-c, the automatic electrical connection device of a high speed hair dryer accessory of the present invention can be disposed in a hair dryer having an ion bar for use with the ion bar. As shown in fig. 6a and 7a, when the ion bar is not inserted, and there is no attraction of magnets, the negative ion contact PCB and the contact are away from the body only by the force of the spring, and the contact does not extend out of the hole of the body; as shown in fig. 6b and 7b, after the ion bar is inserted, the attraction force between the magnet and the magnetic part of the ion bar gradually exceeds the elastic force of the spring 43, so that the ion contact PCB and the contact 45 move toward the body, and finally the contact extends out of the hole of the body, contacts with the ion bar and is electrified, as shown in fig. 6c and 7 c.

Due to the design of the structure, when a user pulls out the ion bar, the two spring contacts are far away from the body only under the force of the springs and do not extend out of the hole of the body any longer to be exposed; even if the user misoperation or other reasons finger stretches into the hollow channel, can not touch the contact and cause the electric shock. Moreover, the structure is simple in design and easy to process, and the existing design of the hair drier body and the ion bar is not required to be changed.

Throughout the description of the present application, it is to be noted that, unless otherwise expressly specified or limited, the terms "mounted," "connected," and "connected" are to be construed broadly, e.g., as meaning either a fixed connection, a removable connection, or an integral connection; may be mechanically connected, may be electrically connected or may be in communication with each other; either directly or indirectly through intervening media, either internally or in any other relationship. The specific meaning of the above terms in the present application can be understood by those of ordinary skill in the art as appropriate.
