Description

Separate electric fan

The present invention relates to an electric fan, in particular, an electric storage unit is provided inside the electric fan, and can be connected with a seat body having an external power supply line for charging, and can be arbitrarily moved and placed.

Press, household appliances have changed a variety of types with the advancement of technology, in addition to achieving basic functionality, control methods (such as remote control, touch...etc.), energy-saving efficiency, safety structure (such as automatic power-off...etc.) The appearance of the shape has gradually become a factor that people will consider when purchasing.

In the case of an electric fan, a general electric fan is connected to a power cord at the base, and the power cord is electrically connected to the motor and the control switch inside the electric fan to pass through the user after the power cord is inserted into the power socket. Pressing the action of the control switch uses an external electric drive motor to operate the fan blades of the electric fan. Since the power cable is connected to the base of the electric fan in a fixed manner, the position of the electric fan is bound to be limited by the position of the indoor and outdoor outlets, especially when the power cable of the electric fan is too short. The range is narrow, and when the power cord is too long, it will occupy the floor space and cause inconvenience of moving and walking. In addition, when the conventional electric fan wants to change the position of the arrangement, the electric fan is required to be lifted and rotated in the desired direction as a whole, so that it is obviously inconvenient to use.

In order to improve the above-mentioned deficiencies, the Chinese Patent Publication No. 10 546 546, discloses a "rechargeable mobile electric fan" which is provided with a rechargeable battery and an inverter between the electric fan motor and the power line, and is provided in the fan holder. By closing the wire box of the power cord, the electric fan can directly supply power through the battery and through the inverter, and can be used to fold the power cable when the battery is not needed, so that the electric fan can be easily moved.

In addition, the Chinese Patent Publication No. 104632648 discloses a "rechargeable electric fan" which is provided with a battery for supplying electric energy in the base of the electric fan, and a charging socket is arranged on the rear side of the base so that the electric fan can be externally connected. The power supply is directly charged and stored, and can be powered by the battery to move and use the electric fan as needed.

In view of the fact that the electric fan directly connects the power cord to the base, so that the electric fan is in the working state, the position of the electric fan is limited to the position of the socket and cannot be moved arbitrarily, and the whole electric fan is required to change the direction of the electric fan. So mentioned, there is still a lack of improvement.

Therefore, the purpose of the present invention is to provide a power supply line for receiving external power to a base body that is not integrally coupled to the body of the electric fan, so that the electric fan provided with the electric storage unit can be electrically connected to the base through the combined mode. The power supply or charging operation is performed, and the power supply of the power storage unit can be supplied after the charging is completed, thereby achieving the purpose of moving the placement position according to the use requirement.

Another purpose of the present invention is to make the electric fan body and the base body conductively contactlessly, so that the electric fan body can pivot directly on the seat body to adjust the direction of the arrangement.

In order to achieve the above objective, the present invention provides a separate electric fan, comprising: a body, the body is provided with a fan portion, a motor for driving the fan portion to operate, and a control panel coupled to the motor; a chassis, the chassis connection Forming a recess in the chassis, and providing an electric storage unit for supplying motor power in the chassis, and connecting the electric storage unit to a first conductive portion; the body, the bump corresponding to the groove being formed above the base And forming a second conductive portion corresponding to the first conductive portion on the bump, and connecting a power line to the second conductive portion; a power converter disposed between the power storage unit and the power line.

Based on the above, the electric fan sets the chassis to the base body while allowing the first conductive portion of the chassis to be electrically connected to the second conductive portion of the base body to connect the external power with the power cord for charging or to operate as an electric fan. Source, and can make the electric fan directly pivot on the seat to adjust the wind direction widely, and when the electric fan has moving demand or cannot use external power, the electric fan chassis is disengaged from the seat to provide electric fan operation through the electric storage unit. Power is required to enhance the flexibility of the electric fan to move and use, and to enhance the practicality.
