Referring to fig. 1 to 4, the embodiment of the present application provides a novel electric heating hair dryer, which includes a hair dryer housing, wherein the hair dryer housing includes an air duct portion 100 and a handle portion 101, the air duct portion 100 and the handle portion 101 are integrally formed, and an air-heating assembly is disposed in the air duct portion 100, it can be understood that the air-heating assembly is a generic name of a fan 201 and a heating component 202 of a conventional hair dryer, a cavity is disposed in the handle portion 101, and a control circuit board 200 is mounted in the cavity, and conceivably, the control circuit board 200 is fixed on a sidewall of an inner cavity of the handle portion 101 by screws, wherein a control unit, a windshield switch 400 and a heat-blocking switch 500 are mounted on the control circuit board 200, the control circuit board 200 is externally connected with a power supply through a power cord, and the power supply, the control circuit board 200 and the air-heating assembly constitute a working circuit, it can be understood that the control circuit board 200 is mounted with electrical components not limited to those described in the above, and the control circuit board 200 is a PCB structure having the same functions as the conventional hair dryer.

The multi-touch sensor 300 is arranged inside the handle part 101, the multi-touch sensor 300 is electrically connected with the control unit, the relay 203 is further arranged on the working circuit, the relay 203 is electrically connected with the control unit, and the relay 203 switches on or off the working circuit according to whether a user contacts the multi-touch sensor 300.

As can be seen from the above, when a user uses the novel electric heating hair dryer provided in the embodiment of the present application, the damper switch 400 needs to be turned on first, and then whether the hot switch 500 is turned on is determined according to the use requirement; then, a user needs to hold the handle part 101 with a hand, when the user touches the multi-touch sensor 300 with the hand, the capacitance of an area of the multi-touch sensor 300 corresponding to the touched position of the hand changes, the control unit enables the relay 203 to be powered on according to the received capacitance change signal to switch on the working circuit, so that the whole working circuit is conducted to form a loop, the electric hair dryer can work normally, when the user removes the hand from the handle part 101, the multi-touch sensor 300 does not have capacitance change any more, and at the moment, the control unit controls the relay 203 to switch off the working circuit, so that the whole working circuit is switched off, and the electric hair dryer stops working. Therefore, it is conceivable that, when a user forgets to turn off the windshield switch 400 and the thermal switch 500 if the user is suddenly powered off during the operation of the novel electric heating hair dryer, after a call comes, the control unit turns off the relay 203 to turn off the working circuit because the handle unit 101 is not in hand contact and the multi-touch sensor 300 is not in capacitance change, so that the hair dryer cannot work normally, and therefore, even when the hair dryer does not turn off the windshield switch 400 and the thermal switch 500, the hair dryer still cannot work if no person contacts the handle unit 101, and thus fire risks cannot occur.

Here, it should be noted that: in this embodiment, the control unit is configured with a touched area value required for turning on the relay 203, when the touched area of the multi-touch sensor 300 is greater than or equal to the set area value, the control unit may turn on the relay 203 to turn on the working circuit, so that the hair dryer operates normally, and conversely, when the touched area of the multi-touch sensor 300 is less than the set area value, the control unit may not turn on the relay 203 to turn on the working circuit, so that the hair dryer cannot operate.

In one embodiment, in order to facilitate the user to hold the handle portion 101, as shown in fig. 1 to 3, the handle portion 101 is provided with a plurality of finger grooves 800, and by means of the finger grooves 800, the user can hold the handle portion 101 with fingers corresponding to the finger grooves 800, thereby facilitating the user to hold the handle.

In an embodiment, in order to enable the area touched by the hand to reach the area value required by the relay 203 to be activated, referring to fig. 1 to 3, notches corresponding to the finger grooves 800 are formed in the positions of the handle portion 101 corresponding to the finger grooves 800, and fingers can be contacted with the multi-touch sensor 300 through the notches, it can be understood that, in order to facilitate installation of the multi-touch sensor 300, in the embodiment, the multi-touch sensor 300 is a curved touch panel, and the multi-touch sensor 300 is attached to the inner wall of the handle portion 101 where the finger grooves 800 are located, so that, based on the design that the finger grooves 800 and the corresponding handle portion 101 at the finger grooves 800 are provided with notches, when a user holds the handle portion 101, the fingers are contacted with the multi-touch sensor 300 through the notches, and the finger grooves 800 guide the positions of the fingers, so that the fingers can be accurately contacted with the multi-touch sensor 300, and the area touched by the hand can reach the area value required by the relay 203 to be activated, which is very convenient.

In one embodiment, in order to mount the multi-touch sensor 300 in the handle 101, referring to fig. 3, the inner wall of the handle 101 is provided with a mounting groove, the mounting groove is recessed outward from the inside of the handle 101 at the side of the finger groove 800, the multi-touch sensor 300 is disposed in the mounting groove, of course, in order to fix the multi-touch sensor 300, a cover plate is disposed on the back of the multi-touch sensor 300, the cover plate covers the multi-touch sensor 300, the cover plate presses the multi-touch sensor 300 onto the handle 101 by a screw, and of course, a plurality of through holes are disposed on the cover plate to facilitate the communication cables between the multi-touch sensor 300 and the control unit.

In an embodiment, since the handle portion 101 is provided with a notch for a finger to touch the multi-touch sensor 300, in order to prevent the multi-touch sensor 300 from being damaged by an impact or other reasons during the process of not using the hair dryer, as shown in fig. 1 to 2, the handle portion 101 is slidably sleeved with a protective rubber sleeve 900, and the protective rubber sleeve can slide up and down along the handle portion 101, so as to cover the notch at the finger slot 800 upwards to protect the multi-touch sensor 300 from being accidentally damaged, and expose the notch downwards, so as to facilitate the user to contact the multi-touch sensor 300 during use, which is very practical.

In one embodiment, in order to minimize the dust entering the inside of the air duct when the electric blowing is not applicable, as shown in fig. 1 to 3, an air outlet is provided at the front end of the air duct portion 100, and a turnover dust cap 600 is hinged at the air outlet through a hinge. Conceivably, when the electric blowing is not used, the dust cap 600 is turned over to lock the air outlet, the air outlet is sealed, dust is prevented from entering the air inlet barrel 100, and when the electric blowing is used, the dust cap 600 is turned over and taken down from the air outlet, so that air is conveniently discharged, and the electric blowing air-conditioning device is very convenient and practical.

In one embodiment, in order to conveniently hang the hair dryer when the hair dryer is not used, referring to fig. 1 to 3, the handle part 101 is provided with a hanging ring 700, and the hair dryer can be hung in a proper position through the hanging ring 700, which is very convenient.

The above description is only exemplary of the present application and should not be taken as limiting the present application, as any modification, equivalent replacement, or improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
