The utility model discloses a working process does:

only the first cellular shade is provided: first base 5 direct mount is on the wall, when not needing the shading, rotates through remote control motor 6 for motor 6 drives second shaft and convolutes cable 8, makes honeycomb curtain upwards shrink, and second base 3 drives upward movements such as motor 6, battery 9. When need the shading or need change battery 9 or maintain, rotate through remote control motor 6 for motor 6 drive second shaft loosens cable 8, makes under the action of self gravity and the gravity of second base 3, first honeycomb curtain 2 is tensile downwards, and second base 3 drives motor 6, battery 9 etc. and moves down, waits to the time second base 3 moves to the window lower extreme, detaches the sealed lid 34 of second, and battery 9 pops out voluntarily, then it can to change new battery 9. When maintenance is required, the motor 6 and the battery 9 can be maintained by detaching the bottom plate 33 from the second housing 31.

The first cellular shade and the second cellular shade are simultaneously arranged: when the second cellular shade 4 and the first cellular shade 2 are both in the closed state (initial state), the second cellular shade 4 and the first cellular shade 2 are both closed, and the pull cord 8 is wound around the second wheel shaft, as shown in fig. 9.

The motor 6 is powered on to start working, the second wheel shaft releases the pull rope 8, the first honeycomb blind 2 and the second base 3 fall freely under the action of gravity until the pull rope 8 is completely released, and the second honeycomb blind 4 is completely opened, as shown in fig. 10.

The motor 6 continues the operation of the previous process, the released pulling rope 8 is reversely retracted to the second wheel shaft, and since the self weight of the second base 3 is greater than the self weights of the third base 1 and the first cellular shade 2, the first cellular shade 2 and the third base 1 rise under the pulling force of the second wheel shaft until the pulling rope 8 is completely retracted, the second cellular shade 4 is retracted, and the first cellular shade 2 is completely opened, as shown in fig. 11.

The motor 6 works in the reverse direction, the pulling rope 8 is released from the second wheel shaft, the second honeycomb blind 4 and the third base 1 freely descend under the action of the dead weight until the pulling rope 8 is completely released, and the second honeycomb blind 4 is completely opened, as shown in figure 10.

The motor 6 continues to work in the reverse direction, the pull rope 8 retracts in the second wheel shaft in the reverse direction, the first cellular shade 2 and the second base 3 ascend under the action of the pull rope 8 until the pull rope 8 retracts into the second wheel shaft completely, and the second cellular shade 4 and the first cellular shade 2 are folded completely to return to the initial state, as shown in fig. 9.

The foregoing is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and replacements can be made without departing from the technical principle of the present invention, and these modifications and replacements should also be regarded as the protection scope of the present invention.
