Description

Has the fan head swinging mechanism that detects element

Technical field

The invention belongs to fan part, particularly a kind of have a fan head swinging mechanism that detects element.

Background technique

As section 1, Fig. 2, Fig. 3, shown in Figure 4, the oscillating head mechanism of its blowing angle of present commercially available fan control is provided with speed reducer A, speed reducer A is made of several gear A 0 that are meshing with each other, the rotation of each gear A 0 of speed reducer A is then controlled by synchronous machine B, the coil B3 of the ac synchronous motor B that this kind is non-carbonate is subjected to electric excitatory and produces magnetic field, so that the rotor B0 of synchronous machine B rotates,, thereby make electric fan produce wobbling action again by the gear B 2 of rotor B0 axle B1 and gear A 0 engagement of speed reducer A.

Only adopt non-carbonate structure because of synchronous machine B itself, be that excitatory magnetic field between its rotor B0 sense of rotation and the coil B3 does not have fixation method, therefore, make that electric fan yaw direction can't be controlled smoothly, promptly, the head of electric fan can reverse voluntarily when being kept out promptly by external force a little, therefore, and as shown in Figure 3, commercially available air-cooling fan, the user is as long as touch out air blade C slightly with hand, and blade C promptly can reverse immediately, and as shown in Figure 4, the traditional type electric fan needs with controlling rod D control electric fan yaw, when the electric fan yaw arrived the swing limit of controlling rod D, electric fan yaw direction can be auto-reverse, and this is the factor because of aforementioned synchronous machine, therefore, uncontrollable at all electric fan yaw direction.

Moreover, aforesaid commercially available known fan, for the yaw direction and the angle and uncontrollable of fan, promptly the existing swaying angle of this kind is the control of the angle that fixed so as to mechanical type controlling rod D.As turn right after 30 °～45 °, auto-reverse again after turning left again and arriving 30 °～45 °, cause its rotation angle to keep mechanical machinery control forever, can't produce preferable swaying angle control.

Summary of the invention

The purpose of this invention is to provide a kind of rotate smooth and easy, have 360 ° of rotating functions, can accurately predict the fan head swinging mechanism that having of rotation angle detects element.

The present invention comprises pedestal, be arranged in the pedestal and have rotating shaft motor, conducting element, detect element and disk body; Pedestal comprises upper shell, lower shell body and coupling shaft; Coupling shaft is fixedly set on the lower shell body and with upper shell and articulates; Motor is fixed on the upper shell, and its rotating shaft and coupling shaft articulate; Disk body is fixed on the lower shell body, which is provided with conductive hoop corresponding with conducting element and contact; Be arranged in the pedestal so as to the element that detects that detects the fan electromotor rotation angle.

Wherein:

Detect element and be arranged at the upper shell below and be arranged at rotating disk on the light of the corresponding effect of blocking blade detect element.

Detect element and be arranged on the rotating disk and be arranged at upper shell in the light of the corresponding effect of blocking blade detect element.

Detect element and be arranged at the upper shell below and be arranged at rotating disk on the Hall element of the corresponding effect of magnetic element.

Detect element and be arranged on the rotating disk and be arranged at upper shell in the Hall element of the corresponding effect of magnetic element.

Because the present invention comprises pedestal, be arranged in the pedestal and have rotating shaft motor, conducting element, detect element and disk body; Pedestal comprises upper shell, lower shell body and coupling shaft; Coupling shaft is fixedly set on the lower shell body and with upper shell and articulates; Motor is fixed on the upper shell, and its rotating shaft and coupling shaft articulate; Disk body is fixed on the lower shell body, which is provided with conductive hoop corresponding with conducting element and contact; Be arranged in the pedestal so as to the element that detects that detects the fan electromotor rotation angle.During motor operation, motor is the center rotation to be articulated in the rotating shaft that is fixedly set on the lower shell body, and drive upper shell simultaneously and rotate relative to lower shell body and the disk body that is fixed on the lower shell body, changing the blowing angle of fan, and make the light that is arranged in the pedestal detect element to detect rotation angle.Not only rotate smooth and easy, have 360 ° of rotating functions, and can accurately predict rotation angle, thereby reach purpose of the present invention.

Embodiment

As Fig. 5, Fig. 6, shown in Figure 7, the present invention can be installed in the arbitrary position of fan 1 skeleton 10, and it comprises pedestal 2, motor 22, light and detects element 23, conducting element 24 and disk body 25.

The lower shell body 21 that pedestal 2 comprises the coupling shaft 221 that is provided with axis hole 222, the upper shell 20 that is provided with pivot hole 201 and is provided with non-circular axis hole 210.

Coupling shaft 221 have the cylindrical section that is rotationally connected with upper shell 20 upper pivot holes 201 2211 and with lower shell body 21 on the corresponding and non-circular shell of column 2212 that places of non-circular axis hole 210.

Lower shell body 21 is provided with several mounting holes 211.

Motor 22 is arranged in the pedestal 2, and is fixedly installed on the upper shell 20, and it has the rotating shaft 220 that is hubbed in coupling shaft 221 upper shaft holes 222.
