Embodiment
For making the object of the utility model embodiment, technological scheme and advantage clearly, below in conjunction with the accompanying drawing of the utility model embodiment, the technological scheme of the utility model embodiment is clearly and completely described.Obviously, described embodiment is a part of embodiment of the present utility model, instead of whole embodiments.Based on described embodiment of the present utility model, the every other embodiment that those of ordinary skill in the art obtain under without the need to the prerequisite of creative work, belongs to the scope of the utility model protection.
As shown in Figure 1, touch electric fan of the present utility model comprises front mesh enclosure 1, rear net cover 2, net hoop 3, fan blade 4, motor 5 and Direct box 6, wherein in Direct box 6, there is control circuit, control circuit is electrically connected with motor 5, by button, knob or remote controller operation fan swicth machine, change fan, the function such as to shake the head.
As shown in Figure 3, the conventional control circuit part of Direct box 6 also comprises the drive circuit of power supply, tutorial light, button, infrared receiver, master control, control fan head, can adopt operation push-button or remote controller, master control is given to LED instruction according to its signal and changes wind speed to the corresponding level of drive circuit to control fan head, shake the head.Its middle fan head is mainly motor portion, provides SC sigmal control by control circuit.Control signal in Fig. 3:
W: this signal conduction, is expressed as gentle breeze shelves;
L: this signal conduction, is expressed as low speed;
M: this signal conduction, is expressed as middling speed;
H: this signal conduction, be expressed as at a high speed, not conductings, then motor stops operating.
As shown in Figure 2,3, touch electric fan of the present invention adds the circuit part of detecting guard in the control circuit of routine, wherein guard can be done as a whole touch area or be divided into zones of different to complete corresponding function, such as front mesh enclosure 1, rear net cover 2 can be divided into respectively the Petting Area of 2-6 formed objects, each Petting Area is electrically connected with circuit for detecting respectively, circuit for detecting is electrically connected with control circuit, preferably, front mesh enclosure 1, rear net cover 2 are divided into respectively the Petting Area of three formed objects.As shown in Figure 4, for detecting touches the circuit diagram of guard part, multiple Petting Areas of front mesh enclosure 1, rear net cover 2 are used as corresponding multiple PAD and are connected to circuit for detecting, detect and whether have hand to touch respective regions.When hand touches guard, circuit for detecting can detect the capacitance variations of respective regions, thus recognizes touch action.Guard 1, rear net cover 2 are connected with circuit for detecting respectively, completely isolated with electrical signal.
