When the wind speed sensor installed on the front of the shell detects that the dehumidified fresh air is lower than the preset wind speed threshold or the wind pressure difference information between the air inlet and the air outlet detected by the wind pressure sensors installed on the front and rear ends of the shell is greater than the preset wind pressure difference threshold, the second gear is driven by the motor to rotate forward, and then the first gear is driven to rotate synchronously through the toothed belt, so as to realize the synchronous forward rotation of the four second rotating shafts in the horizontal direction. At this time, the second rotating shaft drives the first crown gear to rotate forward. At this time, the beveled edge of the meshing teeth of the first crown gear and the beveled edge of the meshing teeth of the second crown gear are subjected to force. At this time, the first crown gear drives the second crown gear to drive the first rotating shaft to perform linear movement in the horizontal direction, thereby pushing the filter plate assembly and causing the filter plate assembly to vibrate with the cooperation of the floating assembly, so as to realize vibration dust removal of the filter plate assembly, thereby increasing the air outlet rate of the fresh air and reducing the wind pressure difference; S3. When the fresh air outlet rate is still lower than the preset wind speed threshold after the filter plate assembly vibrates for two minutes, the motor drives the second gear to reverse, and then drives the first gear to rotate synchronously through the toothed belt, so as to realize the synchronous reversal of the four second rotating shafts in the horizontal direction. At this time, the second rotating shaft drives the first crown gear to reverse. At this time, the right-angled side of the meshing teeth of the first crown gear and the right-angled side of the meshing teeth of the second crown gear are subjected to force. At this time, the first crown gear drives the second crown gear to drive the first rotating shaft to rotate, and the first rotating shaft drives the first pulley to rotate synchronously. The first pulley drives the second pulley to drive the fifth rotating shaft to rotate in the horizontal direction through the transmission of the belt. The fifth rotating shaft drives the flat gear to rotate. The flat gear drives the push plate through the rack meshing with it to push the mounting frame downward, so as to drive the filter plate assembly located at the upper part to move to the position of the filter plate assembly located at the lower part, so as to complete the position replacement of the filter plate assembly, so as to achieve the technical effect of increasing the fresh air outlet rate and reducing the wind pressure difference.

[0012] Further technical solution: A vibration start-up model can be constructed through the temperature, humidity and fan speed of the current environment to obtain the vibration start-up coefficient. When the obtained vibration start-up coefficient is lower than the vibration start-up coefficient threshold, the fan speed is first increased to the upper limit of the speed threshold, and the vibration start-stop coefficient is adjusted. If the obtained vibration start-stop coefficient is still not within the vibration start-stop coefficient threshold, the power component is started to cause the second shaft to rotate forward and vibrate the filter plate assembly. The vibration duration is two minutes. At this time, the second gear is driven by the motor to rotate forward, and then the first gear is driven to rotate synchronously through the toothed belt, so as to achieve the synchronous forward rotation of the four second shafts in the horizontal direction. At this time, the second shaft drives the first crown gear to rotate forward. At this time, the beveled edge of the meshing teeth of the first crown gear and the beveled edge of the meshing teeth of the second crown gear are subjected to force. At this time, the first crown gear drives the second crown gear to drive the first shaft to perform linear movement in the horizontal direction, thereby pushing the filter plate assembly and causing the filter plate assembly to vibrate with the cooperation of the floating component, so as to achieve the filter plate assembly. Vibration dust removal is performed to increase the fresh air outlet rate. After the vibration is completed, the vibration starting coefficient is obtained again. If the obtained vibration starting coefficient is not within the vibration starting coefficient threshold, the motor drives the second gear to reverse, and then drives the first gear to rotate synchronously through the toothed belt, so as to realize the synchronous reversal of the four second rotating shafts in the horizontal direction. At this time, the second rotating shaft drives the first crown gear to reverse. At this time, the right-angled side of the meshing teeth of the first crown gear and the right-angled side of the meshing teeth of the second crown gear are subjected to force. At this time, the first crown gear drives the second crown gear to drive the first rotating shaft to rotate, and the first rotating shaft drives the first pulley to rotate synchronously. The first pulley drives the second pulley to drive the fifth rotating shaft to rotate in the horizontal direction through the transmission of the belt. The fifth rotating shaft drives the flat gear to rotate. The flat gear drives the push plate to push the mounting frame downward through the rack meshing therewith, so as to drive the filter plate assembly located at the upper part to move to the position of the filter plate assembly located at the lower part, so as to complete the position replacement of the filter plate assembly, so as to achieve the technical effect of increasing the fresh air outlet rate.

[0013] Further technical solution: The specific steps of constructing a vibration startup model based on the current ambient temperature, humidity and fan speed are as follows: The obtained temperature information, humidity information and fan speed information are compared with the standard temperature, standard humidity and standard fan speed to obtain the temperature ratio information, humidity ratio information and fan speed ratio information, and the vibration start-up model is introduced to obtain the vibration start-up coefficient. The vibration start-up model is expressed as: ; represents the vibration starting coefficient, Indicates temperature ratio information, Indicates humidity ratio information, Indicates the fan speed ratio information. Indicates the influence factor of temperature ratio information on air outlet velocity, Represents the influence factor of humidity ratio on air outlet rate, Indicates the influence factor of fan speed on air outlet rate.

When the wind speed sensor installed on the front of the shell detects that the dehumidified fresh air is lower than the preset wind speed threshold, the second gear is driven by the motor to rotate forward, and then the first gear is driven to rotate synchronously through the toothed belt, so as to realize the synchronous forward rotation of the four second rotating shafts in the horizontal direction. At this time, the second rotating shaft drives the first crown gear to rotate forward. At this time, the beveled edge of the meshing teeth of the first crown gear and the beveled edge of the meshing teeth of the second crown gear are subjected to force. At this time, the first crown gear drives the second crown gear to drive the first rotating shaft to perform linear motion in the horizontal direction, thereby pushing the filter plate assembly and causing the filter plate assembly to vibrate with the cooperation of the floating component, so as to realize the vibration dust removal of the filter plate assembly and thus increase the air outlet rate of the fresh air; 2. When the fresh air outlet rate is still lower than the preset wind speed threshold after the vibration, the motor drives the second gear to reverse, and then drives the first gear to rotate synchronously through the toothed belt, so as to realize the synchronous reversal of the four second rotating shafts in the horizontal direction. At this time, the second rotating shaft drives the first crown gear to reverse. At this time, the right-angled side of the meshing teeth of the first crown gear and the right-angled side of the meshing teeth of the second crown gear are subjected to force.
