Description

[Detailed description of the invention]

[0001]

[Technical field to which the invention belongs]

 The present invention relates to a fan having two types of swing angles.

[0002]

[Prior art]

 Conventional ordinary fans have only one kind of swing angle and vibrate only in the left and right directions. If you want to adjust the vertical angle, you have to move it by hand. Japanese Patent Application Laid-Open No. 8-121380 (Japanese Patent Application No. 6-278677) discloses a fan provided with two types of oscillating devices and having increased vertical oscillating motion. As shown in FIGS. 4 and 5, the structure is such that a curved groove 1C is provided on the motor base 1, and a continuous zigzag recess 17 is provided on the outside facing the curved groove 1C. The combination metal fitting 3 corresponding to the recess 17 has a projection 18. When the guide 3C of the combination metal fitting 3 is fitted into the curved groove 1C, the recess 17 comes into contact with the projection 18 mutually, When the electric fan rotates, the electric fan swings up and down in a wave shape due to the contact movement between the concave portion 17 and the projection 18 together with the curved swing.

[0003]

[Problems to be solved by the invention]

 However, the above-mentioned electric fan has an improved structure and swings up and down and left and right.However, since the swing in the up and down direction is only a small angle of the wave shape and does not swing at a large angle to blow the wind, The effect is limited. In addition, since the recess 17 and the protrusion 18 are in contact with each other, they are consumed after a long use time, and the vertical swing angle is gradually reduced.

Accordingly, an object of the present invention is to overcome the above-mentioned drawbacks and to provide a fan that swings at a large swing angle in the vertical and horizontal directions.

[0005]

[Means for Solving the Problems]

 A first oscillating device is provided to swing the fan up and down at a large angle, and a second oscillating device is provided to swing the fan at an angle to the left and right. The first swinging device includes an auxiliary motor, an eccentric wheel connected to the shaft of the auxiliary motor, a frame formed integrally with the auxiliary motor and fixed to a rear cover of the fan, and a pivot connected to the eccentric wheel. A fan and an L-shaped position limiting washer fixed to a positioning washer of a fan with a side wall extending forward and having a bottom portion combined with a pivoting piece by screws with two upright guide slots. Swing your head up and down to a large angle. The second swing device is composed of an auxiliary motor, an eccentric wheel connected to the shaft of the auxiliary motor, and a pivot piece pivotally connected between the eccentric wheel and the positioning base below the positioning washer of the electric fan. And the fan's head is swung left and right.

[0006] The two swinging devices can also be operated independently of each other.

[0007]

[Embodiment of the invention]

 Hereinafter, embodiments of the present invention will be described with reference to the drawings. As shown in FIG. 1, a fan having two types of swing angles has a first swing device 20 and a second swing device 30 in a power motor 10 at the head of the fan. The power motor 10 has side holes 101 on both left and right sides thereof, and covers a rear cover 11 at the rear thereof. The rear cover 11 is provided with several holes 111, and a U-shaped stereo washer 13 is provided below the rear cover 11. 10 and stabilize the motor 10. The orienting washer 13 has an orienting hole 131 at the bottom thereof, and has side walls 132 extending upward on both sides, and each of the side walls 132 has an extension 133 extending substantially horizontally rearward. The extension 133 is provided with opposing holes 134 and 135. The hole 134 faces the side hole 101, and the holes 134 and 101 are tightened with bolts, so that the motor 10 is assembled to the stereotactic washer 13. The positioning hole 131 of the positioning washer 13 fits with the dowel 141 of the lower positioning platform 14.

The first swinging device 20 includes an auxiliary motor 21 serving as a power source thereof, a frame 211 integrally formed with the auxiliary motor 21, an eccentric wheel 22 fixed to a shaft 210 of the auxiliary motor 21, A pivot piece 23 having a pivot hole 231 pivotally connected to the eccentric wheel 22 and an outer pivot hole 232 at another end; two guide slots 2410 arranged in a line at the bottom 241; An L-shaped position limiting bracket 24 having a screw hole 2411 facing the pivot hole 232 of the pivot piece 23 between the two guide slots 2410 and a hole 2420 provided in the side 242 extending forward. Prepare.

The second swinging device 30 includes an auxiliary motor 31 serving as a power source thereof, an eccentric wheel 22 connected to a shaft 32 of the auxiliary motor 31, and a pivot connection hole 331 pivotally connected to the eccentric wheel 22. And a pivot piece 33 having a pivot hole 332 fixed to the lower end of the orienting stand 14. In the first swinging device 20, the frame 211 of the auxiliary motor 21 is fixed to the rear lid 11, the orienting washer 13 is connected to the hole 2420 of the position limiting metal fitting 24, and the screw 233 is inserted into the guide slot 2410. The first swinging device 20 is inserted into the hole 111 of the rear cover 11 and assembled to the motor 10 of the electric fan. Further, the second swinging device 30 is installed under the stereotaxic platform 14.

Next, as shown in FIG. 3, when the auxiliary motor 21 of the first swinging device 20 is activated, the shaft 210 rotates the eccentric wheel 22, and the pivoting piece 23 moves up and down regularly. Moving. When the eccentric wheel 22 is actuated, the screw 233 located in the hole 111 is pushed together with the guide slot 2410 to move up and down, and the head of the electric fan vibrates up and down. Is done. Further, in the second swinging device 30, the fan head is vibrated right and left by the operation of the eccentric wheel 22 and the pivot piece 33 by the rotation of the auxiliary motor 31.

As described above, the electric fan having two swing angles according to the present embodiment has the following effects. (1) It can be operated independently, and the user can operate it and shake it up and down or right and left as needed. (2) The second swinging device is not designed to be uneven like a conventional fan, so it does not wear out even when used for a long time.

(3) The first swinging device has a larger swinging angle than the conventional one due to the installation of the eccentric wheel, the pivot piece and the position limiting bracket.
