When the air conditioner works, before the fan is started, the controller controls the fan to be started through preset parameters according to detection data fed back by the electrostatic sensor arranged in the cabinet body 1, air is pumped into the packaging structure from the air inlet and flows upwards, and dust in the air is filtered through the coarse filter layer; silt; debris, and the like.
Referring to fig. 10, the air flows upward, flows along the curved portions respectively, is extruded and accelerated by the diameter-reduced portion 1171, and the air accelerated by the diameter-reduced portion 1171 can push the left moving plate 1161 and the right moving plate 1162 upward and rotate around the insulating rotating shaft 1164; secondly, because the Bernoulli effect has larger flow velocity, the tiny dust particles or other tiny particles can be ensured to be charged, and meanwhile, the tiny dust particles or other tiny particles can not be adsorbed at the reducing part 1171 to cause blockage for a long time; thirdly, the upper part and the lower part of the reducing part 1171 are separated to a certain degree, so that the fine dust particles or other fine particles return to the lower part of the reducing part 1171 again in the extrusion and rebound of the airflow of the reducing part 1171 and are adsorbed on the anode below the reducing part 1171; fourthly, the self-cleaning of the equipment is facilitated, during cleaning, the fan is reversed, the airflow is reversed from top to bottom, before the airflow passes through the reducing part 1171, due to the fact that the passage at the reducing part 1171 is suddenly reduced, the gas in the left flow passage 1166 and the gas in the right flow passage 1167 above the reducing part 1171 are backflushed, so that fine dust particles or other fine particles adsorbed on the anodes at the two sides of the left flow passage 1166 and the right flow passage 1167 can be washed away, meanwhile, the airflow expansion effect is achieved after the airflow is accelerated by the reducing part 1171, so that the fine dust particles or other fine particles adsorbed on the anodes below the reducing part 1171 can be washed away, and the self-cleaning effect of the equipment on the adsorbed fine dust particles or other fine particles is achieved; significantly extending the period of cleaning that requires disassembly of the equipment.
Referring to fig. 9, the air accelerated by the diameter reduction part 1171 pushes the left movable polar plate 1161 and the right movable polar plate 1162 upward to rotate around the insulating rotating shaft 1164, at this time, the micro angle sensor monitors the rotation angle of the left movable polar plate 1161 and the right movable polar plate 1162 and transmits the rotation angle to the controller, and when the rotation angle corresponding to the preset air quality parameter is reached, the controller controls the left fixed polar plate 1172; a right stator plate 1173; the left movable polar plate 1161 and the right movable polar plate 1162 are electrified, and air is ionized for the first time by cathode rays generated between the left fixed polar plate 1172 and the right fixed polar plate 1173; the left movable polar plate 1161 and the right movable polar plate 1162 are electrified to have two functions, namely, a cathode ray is generated between the left movable polar plate 1161 and the right movable polar plate 1172 and the right fixed polar plate 1173 respectively, and secondary ionization is generated on air passing through the left runner 1166 and the right runner 1167; secondly, an electric field is formed between the left movable polar plate 1161 and the right movable polar plate 1162, the strength of the electric field exceeds the transformation critical strength of the electrorheological fluid in the pyramid structure 116, so that the electrorheological fluid is transformed into a solid state, therefore, the shape of the pyramid structure 116 is fixed, the left movable polar plate 1161 and the right movable polar plate 1162 cannot continue to rotate upwards under the action of airflow, the process is almost instantly generated and completed, and the size and the shape of the left flow channel 1166 and the right flow channel 1167 are adjusted at the moment; and the angle of the straight line portions of the left moving plate 1161 and the left fixed plate 1172; and the angles of the straight line parts of the right movable polar plate 1162 and the right fixed polar plate 1173 are adjusted and fixed according to the optimal parameters preset under the total static electricity inside the corresponding ring main unit 1. After the left movable polar plate 1161 and the right movable polar plate 1162 are jacked upwards by airflow to rotate mutually, the controller controls the electrifying time of the left movable polar plate 1161 and the right movable polar plate 1162, so that the included angle between the linear parts of the left movable polar plate 1161 and the left fixed polar plate 1172 can be fixed, and the included angle between the linear parts of the right movable polar plate 1162 and the right fixed polar plate 1172 is also fixed; the difference in this angle can produce different effects:
referring to fig. 12, for example, when the movable electrode plate and the fixed electrode plate are parallel to each other, air in the air can be uniformly ionized, and the effect of adsorbing fine dust particles or other fine particles is more uniform.
Referring to fig. 13, when the angle formed between the straight line portions of the movable plate and the fixed plate makes the left flow passage 1166 and the right flow passage 1167 become large and small, the average distance between the straight line portions of the movable plate and the fixed plate is the largest, and the ionization effect is the weakest; in addition, when the electrode plates enter the left flow passage 1166 and the right flow passage 1167, at a smaller inlet, the fine dust particles or other fine particles are charged quickly when the electrode plates are closer, and since the air flow velocity is faster at this position, the charged fine dust particles or other fine particles are not adsorbed or accumulated, but after passing through this position, due to the rapid increase of the space, an air flow expansion effect occurs when the electrode plates enter the left flow passage 1166 and the right flow passage 1167, the flow velocity of the air flow in the left flow passage 1166 and the right flow passage 1167 is reduced, the residence time of the charged fine dust particles or other fine particles is increased, and turbulence is formed in the left flow passage 1166 and the right flow passage 1167, so that the charged fine dust particles or other fine particles have a higher probability of moving to be adsorbed at the anode, although the ionization effect is not the best due to the angle between the moving electrode plate and the straight line portion of the fixed electrode plate and the average distance is increased, the adsorption effect of the charged fine dust particles or other fine particles by the anode in the left flow passage 1166 and the right flow passage 1167 can be increased, and thus the adsorption effect is not reduced too much.
Referring to fig. 14, when the angle formed between the straight portions of the movable plate and the fixed plate makes the left flow passage 1166 and the right flow passage 1167 become smaller at the top and larger at the bottom, since the distance between the straight portions of the movable plate and the fixed plate gradually decreases from the bottom to the top, the average distance between the straight portions of the movable plate and the fixed plate is the smallest at this time, the ionization effect is strongest, and the ionization capacity thereof gradually increases from the bottom to the top, so that fine dust particles or other fine particles which are more easily adsorbed are adsorbed first, and fine dust particles or other fine particles which are less easily adsorbed are adsorbed later, and thus the adsorption of the fine dust particles or other fine particles is dispersed, and is not concentrated and accumulated, thereby the adsorption capacity of the anode can be better extended.
By combining the preset voltage intensity under the data of the total static parameters in the ring main unit 1 and the dust concentration in the outside air and adjusting the angle between the two movable polar plates, the optimal solution of the preset parameters under different static parameters and dust concentrations is met, and the air purification quality can be obviously improved; the optimal balance between static neutralization capacity and energy conservation and environmental protection can be determined by only carrying out a large number of tests in a laboratory, and the optimal solution is pre-loaded into an equipment system.
In addition, referring to fig. 7, an inverted U-shaped elastic electrode plate 1168 can be connected above the pyramid structure 116, two sides of the elastic electrode plate 1168 are respectively connected to the top ends of the two movable electrode plates, and the connection is isolated by using an insulating material, and there is a smooth transition between the movable electrode plate and the elastic electrode plate 1168 at the connection; the elastic electrode plate 1168 is an anode; the elastic electrode plate 1168 can deform along with the angle change of the two movable electrode plates. The elastic electrode plate 1168 mainly has the following functions: firstly, the coanda effect is utilized to enable the airflow flowing out of the left flow channel 1166 and the right flow channel 257 to be attached to the elastic electrode plate 1168 to flow, so that the adsorption effect on charged impurities and harmful molecules is better; secondly, in the back washing process, the fan rotates reversely, the elastic electrode plate 1168 guides the airflow from top to bottom to enter from the left flow channel 1166 and the right flow channel 257, and the resistance of the airflow is reduced; thirdly, the two movable polar plates are applied with external supporting force and have the tendency of unfolding in the power-off state by matching with the gravity of the electrorheological body, and it should be noted that the foldable surface 1163 should limit the movable polar plates from touching the fixed polar plates when the two movable polar plates are unfolded in the power-off state.
Arc-shaped flow baffles 1169 are respectively arranged at the outer ends of the two flow channels, the middle parts of the arc-shaped flow baffles 1169 are sunken outwards to block and guide the air flow to one side of the elastic electrode plate 1168, and the two arc-shaped flow baffles 1169 are distributed like brackets; the arc flow baffle 1169 is also connected to the top ends of the two fixed pole plates, the connection is isolated by insulating material, and the arc flow baffle 1169 is also an anode and can absorb fine dust particles or other fine particles.
In addition, referring to fig. 11, the counter-cleaning process utilizes bernoulli effect to realize the counter-flushing cleaning and the expansion cleaning through the change of the diameter of the flow channel; secondly, the fine dust particles or other fine particles can be detached from or not attached to the plate by changing the polarity of all the plates or frequently changing the polarity of all the plates, thereby playing a role in cleaning.
The controller automatically receives the electrostatic parameters detected by the electrostatic sensor arranged in the cabinet body 1 and the dust and metal particle concentration detected by the outdoor air detector at intervals, compares the parameters with a prestored database, and calls the control parameters in the corresponding range,
if the control parameters need the two movable polar plates to rotate upwards relative to the current state, the controller controls each polar plate to be powered off, the current variant in the pyramid structure 116 is restored to be liquid, the two movable polar plates continue to rotate upwards under the action of wind pressure, the controller determines that the current of each polar plate is switched on again when the two movable polar plates rotate to the required angle through the miniature angle sensor, the current variant is restored to be solid again under the electric field of the two movable polar plates, and the angles of the two movable polar plates are fixed; and then the controller adjusts the voltage of each electrode plate according to the control parameters, and the rotating speed of the fan reaches the parameter requirement.
If the control parameters need the two movable electrode plates to rotate downwards relative to the current state, the controller controls each electrode plate to be powered off, the current variant in the pyramid structure 116 returns to the liquid state, then the controller controls the fan to stop or reduce the rotating speed, the two electrode plates rotate downwards under the condition that no wind pressure or wind pressure is smaller than the gravity of the current variant and the driving force of the elastic electrode plate 1168 for the downward rotation of the two electrode plates, the controller determines through the micro angle sensor that when the two electrode plates rotate to the required angle, the current of each electrode plate is switched on again, under the electric field of the two movable electrode plates, the current variant returns to the solid state again, and the angle of the two movable electrode plates is fixed; and then the controller adjusts the voltage of each electrode plate according to the control parameters, and the rotating speed of the fan reaches the parameter requirement. The action and the change are all instantaneous, so the time for the regulation and control process is very short and is hardly noticeable.

In this respect, the device realizes the consideration; II, performing secondary filtration; static electricity is removed, static electricity is easily generated and accumulated due to the functions of the electric parts in the ring main unit 1 and the ring main unit 1, and the static electricity is positive or negative due to different materials, so that positive and negative ions can be ionized, and part of the positive and negative ions are driven by airflow or are diffused outwards to enter the ring main unit 1, so that the positive and negative static electricity in the ring main unit 1 is neutralized; moreover, the solubility of the positive and negative ions is low and controllable, so that the harmful influence on the normal work of the electric parts in the ring main unit 1 can be avoided; thirdly, performing primary filtration; the intelligent automatic adjustment can be realized according to the preset parameters, and the adjustment process is stable; high efficiency, thereby realizing the appropriate dust prevention of the ring main unit 1; the combination of static electricity removal and heat dissipation functions; fourthly, performing secondary filtration; has better self-cleaning function.
