Detailed Description

In order to make the objects, technical solutions and advantages of the present invention more clearly understood, the present invention is further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.

In the description of the present invention, it should be noted that the terms "center", "upper", "lower", "left", "right", "vertical", "horizontal", "inner", "outer", and the like indicate orientations or positional relationships based on the orientations or positional relationships shown in the drawings, and are only for convenience of description and simplification of description, but do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and thus, should not be construed as limiting the present invention; the terms "first," "second," and "third" are used for descriptive purposes only and are not to be construed as indicating or implying relative importance; furthermore, unless expressly stated or limited otherwise, the terms "mounted," "connected," and "connected" are to be construed broadly, as they may be fixedly connected, detachably connected, or integrally connected, for example; the two components can be directly connected or indirectly connected through an intermediate medium, and the two components can be communicated with each other. The specific meaning of the above terms in the present invention can be understood in specific cases to those skilled in the art.

Please refer to fig. 1 to 3, which illustrate a touch-control electric hair dryer provided by the present invention, which includes a housing, and a hair-dryer power assembly, a heating assembly, a circuit board and a flexible multi-touch sensor 1 accommodated inside the housing. Wherein, the shell is equipped with dryer 21 and handle 22, is provided with the control unit who is used for controlling power component and the heating element operation of blowing on the circuit board.

The flexible multi-touch sensor 1 is attached to the wall surface inside the handle 22, and the flexible multi-touch sensor 1 is integrally in a sheet shape and can be elastically bent and deformed. It is easily understood that the flexible multi-touch sensor 1 of the present embodiment has the characteristics of lightness, thinness, flexibility, and foldability, and can be attached to various object surfaces, such as irregular surfaces, for example, curved surfaces.

Referring to fig. 4, the flexible multi-touch sensor 1 is electrically connected to the control unit. When a user touches the outer surface of the handle, the capacitance of the flexible multi-point touch sensor 1 and the area corresponding to the touched position of the handle changes, the control unit obtains touched position information and a touch direction according to the received capacitance change signal, and sends corresponding operation instructions to the blowing power assembly and the heating assembly so as to control the opening and closing of the blowing power assembly and the heating assembly or adjust the air volume and the temperature.

Specifically, the electric hair dryer can be started or closed through the following two schemes:

in the first scheme, the number of touched positions required for starting the blowing power assembly and the heating assembly is set in the control unit. When the number of the touched positions on the outer surface of the handle 22 is larger than or equal to the set number value, the control unit controls the blowing power component and the heating component to be started. When the handle 22 is not touched or the number of touched positions is less than the set number, the control unit controls the blowing power assembly and the heating assembly to be turned off.

And in the second scheme, the touched area value required for starting the blowing power component and the heating component is set in the control unit. When the touched area on the outer surface of the handle 22 is larger than or equal to the set area value (for example, if the hair dryer is to be automatically turned on when the user touches the handle 22 with three fingers at the same time, the touched area for starting the hair dryer can be set as the area where the three fingers contact the handle 22), the control unit controls the blowing power component and the heating component to be turned on. When the user puts down the handle 22 and the outer surface of the handle 22 is not touched, the touched area of the handle 22 is smaller than the set area value, and the control unit controls the blowing power component and the heating component to be closed.

The control unit obtains control instructions of air volume and temperature according to the direction of the user touching the outer surface of the handle 22. When the touch direction is from bottom to top along the outer surface of the handle 22, the control unit controls the heating component to increase the heating value (i.e. increase the temperature); when the touch direction is from top to bottom along the outer surface of the handle 22, the control unit controls the heating assembly to reduce the heating amount (namely reduce the temperature), when the touch direction is from left to right along the outer surface of the handle 22, the control unit controls the blowing power assembly to increase the air volume, and when the touch direction is from right to left along the outer surface of the handle 22, the control unit controls the blowing power assembly to reduce the air volume.

In order to ensure the touch sensitivity, the thickness of the handle 22 is not more than 5mm, and the material of the handle 22 may be plastic, leather, or wood.

In summary, the touch-control type electric hair dryer of the present embodiment has the following advantages:

1. the flexible multi-point touch sensor 1 can be well attached to the inside of the handle 22, the outer surface of a product is not affected, meanwhile, a hole groove does not need to be additionally formed in the handle 22 to configure a mechanical switch, the appearance of the whole machine is not damaged, the overall appearance of the product is improved, and the waterproof and anti-creeping performance of the product is improved. A

The above description is only exemplary of the present invention and should not be taken as limiting the scope of the present invention, as any modifications, equivalents, improvements and the like made within the spirit and principles of the present invention are intended to be included within the scope of the present invention.
