[0002] With the improvement of living standards, more and more lamps and fans are used at the same time in many homes, offices or other places; therefore, many fan lamps appear on the market, mainly fan chandeliers, which combine the functions of ceiling fans and lamps. The blades of some existing ceiling fans can be expanded and retracted. When the blades of the ceiling fan are in the expanded state, the wind force of the ceiling fan is the largest. When the blades of the ceiling fan are in the retracted state, the blades have a good concealing effect, which can improve the decorative effect of the ceiling fan in the room.

[0003] However, in the existing technology, the direction of the fan blades is usually fixed downward, and the wind radiation range of the ceiling fan is only the position below the fan. When the user sits in a position away from the bottom, the ceiling fan cannot blow air to the user, and the practicality is low.

[0004] Therefore, it is necessary to invent an electric fan with hidden blades to solve the above problems. Utility Model Content

[0005] The utility model aims to provide an electric fan with hidden blades, so as to solve the problem that the wind radiation range of the ceiling fan in the technology is only the position below the fan. When the user sits in a position deviated from the bottom, the ceiling fan cannot blow air to the user, resulting in low practicality.

[0006] In order to achieve the above-mentioned purpose, the utility model provides the following technical solutions: an electric fan with hidden blades, comprising a mounting plate, a first device shell being fixedly connected to the lower surface of the mounting plate, a second device shell being arranged below the first device shell, an adjustment mechanism being arranged inside the first device shell and the second device shell, the adjustment mechanism comprising an electric motor, a rotating disk, a fixing rod, a transmission gear and a driving gear, the upper end of the fixing rod being fixedly connected to the rotating disk, and the fixing rod on the inner side of the first device shell being fixedly connected to the upper end of the second device shell.

[0009] By adopting the above technical solution, the adjustment mechanism inside the first device shell drives the fixing rod to rotate left and right, thereby driving the second device shell on the lower side to rotate, and the adjustment mechanism inside the second device shell drives the fixing rod to rotate forward and backward.

[0010] Optionally, the driving gear is rotatably connected to the upper side of the equipment slot, the electric motor is fixedly mounted on the outside of the first equipment housing and the second equipment housing, and the output end of the electric motor is fixedly connected to the driving gear.

[0011] By adopting the above technical solution, the electric motor is used to drive the driving gear to rotate.

[0012] Optionally, the rotating disk is rotatably connected to the lower ends of the first device housing and the second device housing respectively, the side surface of the rotating disk is fixedly connected to the transmission gear, and the transmission gear is meshingly connected to the driving gear.

[0013] By adopting the above technical solution, the driving gear drives the transmission gear to rotate, and the transmission gear drives the rotating disk to rotate.

[0014] Optionally, the lower end of the fixing rod inside the shell of the second device is fixedly connected to a connecting shell, a driving mechanism is provided on the inner side of the connecting shell, a mounting seat is transmission-connected to the side of the connecting shell, and four groups of exhaust fan blades are rotatably connected to the upper surface of the mounting seat.

At the same time, when the exhaust fan blades expand, they will drive the connecting rod to rotate, and the connecting rod will squeeze the torsion spring, thereby causing the torsion spring to generate tension. When not in use, the tension of the torsion spring will retract the exhaust fan blades to above the lighting lamp, thereby hiding and protecting the exhaust fan blades and improving the overall aesthetics.

When the user sits at a position deviated from the lower position, the ceiling fan cannot blow air to the user at this time, which has low practicality.

The tension of the torsion spring will retract the exhaust fan blades to above the lighting lamp, thereby hiding and protecting the exhaust fan blades and improving the overall aesthetics.
