The rotation of the second rotating shaft will drive the fourth connecting rod to move up and down. The up and down movement of the fourth connecting rod will pass through the U-shaped frame and the third connecting rod, so that the second connecting rod performs a lever movement under the activity or hinge action of the U-shaped frame and the first limit block, and the end of the second connecting rod away from the first limit block is pushed upward, so that the lifting device can lift the filter screen on the first turntable to the purification chamber;

[0073] When the switching mechanism works through the rotation of the fourth rotating shaft, the specific operation is as follows: the fourth rotating shaft rotates, driving the connecting disk to rotate, the first connecting rod and the arc-shaped baffle connected to the connecting disk rotate together, further causing the protruding block and the shifting rod to rotate together, the protruding block and the shifting rod to make a circular motion around the axial center line of the fourth rotating shaft, and to shift the shifting holes arranged at intervals on the hemisphere, so that the hemisphere can rotate through the first rotating shaft and the bearing seat, when the first rotating shaft rotates, it will drive the first rotating disk to rotate, further realizing the rotation of the storage box arranged on the upper surface of the first rotating disk, after the storage box rotates, the storage box with the new filter screen will be rotated to the core outlet hole position of the replacement shell, and then the new filter screen will be pushed out of the storage box and the replacement shell by the lifting mechanism, and arrive at the purification room for use; and when the lifting device moves downward, the old filter screen will fall into its corresponding storage box, thereby achieving the purpose of replacing the filter screen;

[0074] Furthermore, in order to clearly check the condition of the filter in the storage box, the second gear engages with the first gear during rotation, and the first gear rotates with the third shaft, and the third shaft rotates with the indicator plate. At least four display marks are provided on the display panel, and each display mark corresponds to a storage box one by one, and the display marks are arranged in numerical order. The initial state of the indicator plate is 1, and the terminal state is 4. When the fourth shaft rotates, the switching mechanism and the lifting mechanism work together to replace the old filter, and the indicator plate accumulates once and rotates accordingly to the display mark of the filter in use. This makes it convenient for the user to see the use status of the filter at any time during use, and it is convenient to store new filters in the storage box again after the filters in the storage box have been replaced.

[0075] Therefore, the controller receives the fan speed, and when the fan speed value exceeds the preset value, the controller starts the motor and realizes that the motor drives the fourth shaft, so that the fourth shaft first drives the lifting mechanism through the cam, so that the lifting mechanism drops the old filter and enters the storage box corresponding to the filter; then according to the rotation of the fourth shaft, the switching mechanism drives the first turntable, and places the storage box storing the new filter at the position of the core outlet hole; then the lifting mechanism is driven by the movement of the cam to lift the new filter from the storage box storing the new filter, and reaches the purification chamber from the core outlet hole, thereby achieving the purpose of replacing the new filter with the old filter; further, the fourth shaft is used to drive the indicator plate to work together, and the indicator arrow of the indicator plate points to the position of the indicator mark of the currently used filter, so that the user can check the use status of the filter at any time; therefore, it is greatly improved that the filter can always be in an effective filtering state, and the fresh air efficiency of the fresh air system is greatly improved; and the secondary pollution caused by dust accumulation on the filter or the failure of the fresh air system is reduced.

[0076] Obviously, those skilled in the art can make various changes and modifications to the present invention without departing from the spirit and scope of the present invention. Thus, if these modifications and variations of the present invention fall within the scope of the claims of the present invention and their equivalents, the present invention is also intended to include these modifications and variations.
