Each branch part between the filter barrel 8 and the third connecting pipe 5 is provided with a first pressure valve 23, the first connecting pipe 3 is provided with a second pressure valve 24, the two pressure valves are in a closed state under a normal working state because the gas pressure can not reach the opening pressure of the pressure valve, and when the slide block 12 or the baffle 20 seals the corresponding pipeline space, the pressure valves can be broken under the action of air pressure, so that the change of a gas flow channel is realized, and the normal work is not influenced, the third connecting pipe 5 is made of PU hose material and has the capability of deformation, so that when the rotating plate 15 rotates under the action of air pressure, the third connecting pipe 5 has a deformation space, the gap between the third connecting pipe 5 and the rotating plate 15 is avoided, the connection part of the second connecting pipe 4 and the filter barrel 8 is positioned at the outer ring part of the filter screen 9, so that the gas is introduced into the outer ring from the inside of the filter screen 9 under the filtering action and outputs clean air, the junction of the fourth connecting pipe 6 and the filtering barrel 8 is located at the center of the bottom of the filtering barrel 8, when the sealing plate 10 is located at the bottom of the filtering barrel 8, the junction of the fourth connecting pipe 6 and the branch pipe 2 with the filtering barrel 8 is sealed, and when the sealing plate 10 moves upwards under the driving of the push rod 13, the fourth connecting pipe 6 is unsealed, and the air entering the lower filtering barrel through the branch pipe 2 is filtered again and then output.
The filter screen 9 is divided into two funnel structures which are formed by integrally connecting two annular structures and have wide upper layers and narrow lower layers; the lower floor adopts thin wall cylinder mechanism, the junction diameter of upper strata and lower floor is the same, closing plate 10 constitutes for a ring magnet and a circular iron plate jointly, circular iron plate and the sealed sliding connection of the 9 lower floor inner walls of filter screen, ring magnet and the same height of circular iron plate and inside and outside respectively with the sealed laminating of 9 lower floor inner walls of filter screen and 8 inner walls of filter vat, ring magnet and circular iron plate inter attraction, make when circular iron plate shifts up under the effect of push rod 13, ring magnet shifts up under the effect of magnetic attraction in step, and the 8 inner walls of common seal filter vat, make filter vat 8 divide into two filtration spaces.
When the gas filtering device is used, in a normal working state, as shown in fig. 4, compressed air enters through the inlet pipe 1, enters the inner ring of the filter screen 9 through the third connecting pipe 5 under the flow guiding effect of the branch pipe 2, and the gas in the inner ring is outwards diffused by the continuous entering of the compressed gas, enters the outer ring of the filter screen 9 under the filtering effect of the filter screen 9 and is discharged through the second connecting pipe 4 and the outlet pipe 7, so that the gas filtering work in the normal working state is realized;
in this state, the flow rates of the gas entering the filtering barrel 8 and the gas flowing out of the filtering barrel 8 are the same in a unit time, so that the inside and the outside of the filtering barrel 8 are kept in dynamic balance, the sealing plate 10 is positioned at the bottom of the filtering barrel 8, the first spring 17 keeps a natural length, the moving rod 18 is positioned at the lower end outside the filtering barrel 8, and the baffle plate 20 cannot seal the outlet pipe 7;
when one of the filter tanks 8 is subjected to dust accumulation, since the filtering direction of the filter screen 9 is always from the inner side to the outer side, so that a large amount of dust always deposits on the inner side of the filter net 9, and at this time, since the filtering effect is reduced and the filter holes are largely blocked, it is equivalent to the filter net 9 sealing the inner space thereof, so that the inflow speed of the gas per unit time is larger than the outflow speed, therefore, the air pressure in the internal space of the filter screen 9 is increased, and at the moment, the air has the force of expanding the relative sealed space, the space sealed by the filter screen 9, the rotating plate 15 and the sealing plate 10 tends to be relatively large when sliding upward, the air pressure drives the push rod 13 to slide upwards, the sliding block 12 fixedly connected with the push rod 13, the moving rod 18 and the sealing plate 10 simultaneously realize three functions, and the corresponding branch part is sealed by the movement of the sliding block 12; the movement of the mobile rod 18 causes the abutment 21 to push the shutter 20 upwards and eventually seal the outlet tube 7; the upward movement of the sealing plate 10 opens the joint of the branch pipe 2 and the filtering barrel 8 and simultaneously ends the sealing state of the fourth connecting pipe 6, and simultaneously divides the filtering barrel 8 into two filtering spaces which are independent from each other; the final flow direction of the gas is shown in fig. 5, the gas passes through the filter vat 8 without dust deposition on the other side, enters the second connecting pipe 4 after being filtered, because the outlet pipe 7 is sealed, the gas passes through the second connecting pipe 4 on the other side and reversely enters the upper filtering space of the filter vat 8 to be cleaned, and is input inwards from the outer side of the filter screen 9, the dust on the inner side is removed, and reversely enters the third connecting pipe 5 along with the air, enters the lower filtering space of the filter vat 8 after breaking the pressure valve on the branch pipe 2, and enters the outlet pipe 7 through the fourth connecting pipe 6 after being filtered again and is output; the device has the advantages that the process of cleaning dust on the filter screen does not influence the discharge of compressed air, so that the output of the atomized liquid medicine driven by the compressed air cannot be stopped when the device is used under the self-cleaning action, the atomized liquid medicine is always in a continuous output state, the input of the liquid medicine cannot be disconnected, the patient is always treated by the atomized liquid medicine driven by clean compressed air in an emergency state, and the treatment effect is improved;
when the two filter screens 9 are simultaneously subjected to dust deposition, the air at the inlet breaks through the second pressure valve 24 and reversely enters the filter barrel 8 through the first connecting pipe 3, the flowing principle is the same as that of the one filter screen 9, and the gas flowing channel can be shown in fig. 6, so that the two filter screens 9 can be cleaned simultaneously.
In conclusion, when the impurity content in the air is not large and the dust does not need to be removed completely, the back washing principle in the device is utilized to continuously separate the dust deposited on the filter screen 9, so that the cleanliness of the air is not influenced during output, the treatment work of a patient in a medical atomization device, particularly in an emergency treatment or rescue state, is facilitated, the effect of self-cleaning the filter screen 9 is realized, and the workload of workers is reduced.
