With reference to fig. 5 and 9, the sleeve seat includes a tubular seat body 51, a bearing 52, a housing 53 and a deflection detecting assembly 6; the seat body 51 is fixedly arranged at the tail end of the handle 2 in a penetrating way; the bearing 52 is positioned in the seat body 51 and is in axial sliding fit with the inner wall of the seat body 51; the sleeve 43 is fixedly sleeved on the inner ring of the bearing 52.
Referring to fig. 5, 8 to 10, the deflection detecting unit 6 is fixed to one end of the base 51 for detecting the deflection direction of the sleeve 43. The deflection detection assembly 6 comprises a ring seat 61, a first reed pipe 65, a second reed pipe 66, a first spring 63, a second spring 64 and a movable block 62; the ring seat 61 is C-shaped and is fixedly connected with the seat body 51; the two ends of the ring seat 61 are circumferentially provided with first arc-shaped rods 611; the movable block 62 is fan-shaped and concentric with the ring seat 61, and has two ends provided with a second arc-shaped rod 624 along the circumferential direction, the first arc-shaped rod 611 is hollow, and one end thereof is provided with an arc-shaped slot 6111; the end part of the second arc-shaped rod 624 is provided with an arc-shaped inserted rod 6241 matched with the arc-shaped slot 6111; an accommodating cavity is formed in the ring seat 61 close to the arc-shaped slot 6111, and the first reed pipe 65 and the second reed pipe 66 are respectively positioned in the accommodating cavity on the two sides of the ring seat 61; the arc-shaped plunger 6241 is made of a magnetic material. The first spring 63 and the second spring 64 are respectively sleeved on one pair of the first arc-shaped rod 611 and the second arc-shaped rod 624. When any one arc-shaped inserting rod 6241 is completely inserted into the arc-shaped slot 6111, the first reed pipe 65 or the second reed pipe 66 is triggered, and the rotating block 421 in the coupling 41 just abuts against one of the fan-shaped limiting blocks 4111 on the two sides; therefore, it can be considered that the yaw angle of the turning block 421 is the same as the yaw angle of the movable block 62.
In addition, referring to fig. 10, the movable block 62 includes a main block 621 and a sub-block 622; the sub-block 622 may be made of iron as a whole, or a layer of iron may be provided at the front end of the sub-block 622 to attract the magnet 431. One side of the main block 621 is provided with a movable slot 6211 adapted to the auxiliary block 622; one end of the secondary block 622 is connected with the bottom of the movable slot 6211 through a third spring 623; in order to prevent the secondary block 622 from being separated, a first limit ring 6212 is detachably disposed in the notch of the movable slot 6211, and a second limit ring is formed on the secondary block 622. When the sub-block 622 extends to the maximum position, the distance between the sub-block 622 and the magnet 431 is smaller than the depth of the first conductive groove 211, that is, when the first conductive head 212 does not fully extend out of the first conductive groove 211, the magnet 431 is attracted to the sub-block 622.
Referring to fig. 2, a control device 33 is further installed in the connection section 21, the control device 33 has a power taking end 331, and the power taking end 331 is electrically connected with the first conductive slot 211 through a wire; the first reed switch 65, the second reed switch 66, the motor 32, the telescopic driver 31, the deflection detecting assembly 6 and the control device 33 are electrically connected. The control device 33 may be built with a lithium battery that is automatically charged by the power take-off terminal 331 when the hair dryer is in operation.
In the following, the present embodiment is described in detail with respect to the automatic recovery principle of the intelligent hair dryer:
s01, in the initial state, the control device 33 controls the telescopic driver 31 to reset, so that the first conductive contact 212 enters the first conductive slot 211.
S02, the control device 33 judges whether the power plug of the intelligent blower is inserted into the socket or not by detecting whether the power taking end 331 is electrified or not; if yes, the control device 33 controls the telescopic driver 31 to extend to push the first conductive head 212 out of the first conductive slot 211; at this time, the magnet 431 on the sleeve 43 is already attracted to the auxiliary block 622 on the movable block 62, and when the torsion force generated by the torsion of the power cord 7 is too large, the movable block 62 is deflected, and the corresponding arc-shaped inserted rod 6241 triggers the first reed pipe 65 or the second reed pipe 66.
S03, the control device 33 judges the deflection direction of the movable block 62 through the feedback signals of the first reed switch 65 and the second reed switch 66;
s04, the control device 33 controls the telescopic driver 31 to reset, so that the first conductive head 212 returns to the first conductive slot 211 again, and then controls the motor 32 to rotate forward or backward for a predetermined number of turns N according to the deflection direction of the movable block 62, where N = N1+ N2, N1 is an integer, and N2 is the deflection angle of the movable block 62 when the first reed pipe 65 or the second reed pipe 66 is triggered. Due to the left-right balance function of the first spring 63 and the second spring 64, when the torsion degree of the power cord 7 is insufficient, the deflection amplitude of the movable block 62 cannot enable the arc-shaped plunger 6241 to trigger the first reed pipe 65 or the second reed pipe 66, and at this time, the power cord 7 does not need to be adjusted, so that the control device 33 does not need to control the motor 32 to rotate. In actual manufacturing, an approximate value of N can be obtained through testing, i.e., the power cord 7 is twisted until the reed switch is triggered; this special case need not be taken into account heavily, since in general the probability of the power line 7 being twisted up to 2N times during one use is very low. However, in order to take such a situation into consideration, the controller 33 may be provided to control the extension/contraction driver 31 to extend again after step S04, and the step S03 may be repeated.
The above are only typical examples of the present invention, and besides, the present invention may have other embodiments, and all the technical solutions formed by equivalent substitutions or equivalent changes are within the scope of the present invention as claimed.
