Description

Electric fan structure improvement

The present invention relates to an improvement of an electric fan structure, in particular, the electric fan remote controller is laterally received in a receiving cavity at a position of the electric fan and is pushed by an elastic member against the cavity wall of the accommodating cavity, and does not slip. And the power converter is arranged in the handle facing the fan end, which can quickly dissipate heat to prolong the service life.

According to the conventional electric fan, the electric fan is disposed above the motor casing, and a horizontal handle is disposed in the air. In addition to being convenient for carrying the electric fan, the touch panel for controlling the operation of the electric fan can be disposed on the handle. The top surface is convenient to operate the switch. In addition to the configuration of the touch panel, the handle type electric fan has a model in which a remote controller is developed, and the electric fan is controlled by a touch and remote control mode. Moreover, in order to supply the power of the touch panel, a power converter must also be provided. However, conventional electric fans have the following drawbacks in use and need to be improved.

1. It is customary to provide a slot for receiving the remote control, most of which is externally displayed and the notch is facing upward, so that the remote controller is placed into the placement slot from top to bottom. For example, the patent number: M533131, M515037 and so on. Although the remote control of another patent number: M478750 patent is horizontally placed, it is provided with a pocket in the headstock, the slot of the slot is upward and the aperture is equivalent to the outer diameter of the remote controller, so that the remote controller It can be placed from the top to the bottom and placed in the tank. It is also placed from top to bottom. When the remote controller is removed and not returned to the original slot position, the slot is separately displayed, which destroys the overall appearance of the fan.

2. The above-mentioned power converter is prone to heat when it is started. If the generated heat is not discharged and the surrounding temperature is high, the power converter is likely to malfunction due to the high temperature environment, or even affect the service life. For example, in Taiwan Patent No. M533132, "Modified Electric Fan Assembly Structure", the power converter is disposed at the rear end of the motor casing and covered by a casing. Although the casing is provided with a heat dissipation hole, the installation position is Adjacent to the motor, when the motor is started, high temperature is also generated, which causes the cooling effect of the power converter to be ineffective and affects the service life.

The handle 33, as shown in FIG. 5, is composed of a cover 330 and an upper cover 331. The front end of the box body 330 is the same as the front case 310, and extends from the top end of the front case 310 and then extends horizontally back. The box body 330 is recessed at the bottom with a horizontally extending receiving cavity 332. The inlet 3320 of the receiving cavity 332 faces the rear of the electric fan 1 (ie, horizontally), and the opening 3320 can be laterally pushed into the remote controller. 40 enters the receiving chamber 332 for retraction. One of the horizontally-facing cavity walls 3321 of the interior of the accommodating cavity 332 (for example, the cavity wall on the bottom side of the embodiment) is disposed with an elastic member 333 extending from the cavity wall 3321, and the elastic member 333 is divided. The edge away from the end of the inlet 3320 is connected to the cavity wall 3321, and the other side has a gap with the cavity wall 3321, so that the elastic member 333 has a longitudinal elastic force for pushing inside the receiving cavity 332. The elastic member 333 is disposed near the end of the inlet 3320 and disposed toward the interior of the receiving cavity 332. The top surface of the top block 3330 is an inclined pushing surface 3331. The pushing surface 3331 is thinner near the inlet 3320. When the remote controller 40 is pushed into the accommodating cavity 332 by the inlet 3320, the bottom surface of the remote controller 40 can smoothly pass through the pushing and unloading surface 3331, and the elastic member 333 is slightly pressed outward when the remote controller 40 is inserted. When positioned in the accommodating cavity 332, the elastic member 333 and the top block 3330 thereof return to the original position, and the remote controller 40 is placed in the accommodating cavity 332, so that the remote controller 40 is not easily loosened and slid out of the accommodating cavity 332.
