The accessory unit 8 comprises a flap 81. The blocking cover 81 is located between the body 2 and the air supply duct 5 and the air exhaust duct 6, and has an air supply hole 811 and an air exhaust hole 812. The air supply hole 811 is communicated with the air injection chamber 211 and the air supply duct 5, but is not communicated with the lower layer suction chamber 212. The exhaust holes 812 communicate with the upper layer suction chamber 221 and the exhaust duct 6.

The first embodiment is adapted to be connected to a supply air blower (not shown) and an intake air blower (not shown) for removing dust (not shown) from an object (not shown) to be cleaned. The steps of the first embodiment for dust removal are as follows: air feed blower connect in air feed tuber pipe 5, the air feed blower connect in exhaust tuber pipe 6, the air feed blower blows in the air jet chamber 211, the air supply hole 811 of fender lid 81 makes the air only can get into air jet chamber 211 can not get into lower floor suction chamber 212, air jet chamber 211 is used for providing jet-propelled pressure accumulation space in order to maintain jet-propelled pressure, the air feed blower that breathes in attracts the air in upper strata suction chamber 221, upper strata suction chamber 221 is used for increasing inspiratory buffer space in order to maintain dust removal effect, as air in air jet chamber 211 by air jet unit 213 air jet 218 blowout, and blow loose when treating the dust on the dust removal thing, contain the air of dust by air inlet 219 is attracted to corresponding lower floor chamber 212, again according to the preface via each suction channel 4 narrow channel district 41 and wide channel district 42 gets into upper strata suction chamber 221, since the narrow passage section 41 has a smaller width than the wide passage section 42, the efficiency of flow guiding and air suction can be improved, and finally, the air containing dust is discharged by the air suction blower through the exhaust air duct 5.

It should be noted that each of the suction ports 219 of each of the suction port units 214 is not limited to a straight line, and may have a circular hole shape and be arranged at intervals in the length direction as shown in fig. 8. Therefore, the air inlets 219 are formed in a circular hole shape and arranged at intervals, and are not communicated with each other, so that the processing accuracy can be improved and the overall rigidity of the body 2 can be maintained.

It should be noted that the gas ejection ports 218 of the gas ejection port unit 213 are not limited to a straight line, and may be formed in a wave shape and extend in the length direction as shown in fig. 9. Therefore, the air injection ports 218 are wavy, so that the air injection range along the width direction when the air is injected from the air injection ports 218 can be increased, dust in a larger range is blown away, and the dust removal efficiency is improved.

Referring to fig. 10, a second embodiment of the gas circulation device of the present invention is substantially the same as the first embodiment, and also includes the main body 2 (fig. 4), the housing 3 (fig. 4), the suction channel 4 (fig. 7), the air supply duct 5 (fig. 4), the air exhaust duct 6 (fig. 4), and the cover 7 (fig. 4). The difference lies in that:

the upper deck 22 also has eight louvers 225. Each louver 225 covers the corresponding upper layer side opening 222 and has a plurality of through holes 226 communicating the corresponding upper layer side opening 222 and the corresponding suction channel 4. The number of perforations 226 per shield 225 increases with increasing distance from the exhaust end 223 and the exhaust stack 6 (fig. 4).

When the length of the body 2 exceeds 1 m, the suction pressure in the upper suction chamber 221 is reduced as the distance from the discharge end 223 is increased, so that the suction range is reduced to lower the suction efficiency. The number of the through holes 226 of each louver 225 increases with the distance from the exhaust end 223, so that the suction pressure during suction can be increased, the overall suction pressure in the upper suction chamber 221 can be kept balanced, and the suction range can be increased.

Referring to fig. 11 and 12, a third embodiment of the gas circulation device of the present invention is substantially the same as the first embodiment, and also includes the main body 2 (see fig. 4), the housing 3, the suction passage 4 (see fig. 7), two air supply pipes 5, two air exhaust pipes 6, and the accessory unit 8. The difference lies in that:

the lower deck 21 also has 16 lower deck side openings 215 and two supply ports 216 in opposite directions. The upper deck 22 also has 16 upper deck side openings 222, two opposite exhaust ends 223, and 16 louvers 225. The air supply pipe 5 is connected to the corresponding air supply end 216, and the air exhaust pipe 6 is connected to the corresponding air exhaust end 223. The accessory unit 8 comprises two flaps 81.

The number of the through holes 226 of the shroud 225 adjacent to the corresponding exhaust end 223 is the smallest, the number of the through holes 226 of the shroud 225 away from the exhaust end 223 is the largest, and the number of the through holes 226 of each shroud 225 increases with the distance from the corresponding exhaust end 223.

When the length of the body 2 exceeds 1 meter or the dust removal and air cleaning effects need to be improved, the air supply duct 5 and the air exhaust duct 6 of the third embodiment are suitable for being connected with a corresponding air supply blower (not shown) and a corresponding air suction blower 6 (not shown) to maintain the air injection pressure of the air injection chamber 211 and the air suction pressure of the upper layer air suction chamber 221, so as to improve the dust removal and air cleaning effects.

From the above description, the advantages of the foregoing embodiments can be summarized as follows:

1. the lower side opening 215, the upper side opening 222, and the air inlet 219 are arranged at intervals and do not communicate with each other, so that the processing accuracy can be improved and the overall rigidity of the main body 2 can be maintained.

2. In the case that the width of the body 2 is not increased, the upper suction chamber 221 of the upper layer 22 increases the whole suction buffer space, so that the volume sizes of the air ejection chamber 211 and the lower suction chamber 212 of the lower layer 21 are not limited to each other, and thus the air ejection chamber 211 can maintain the air ejection pressure and the upper suction chamber 221 can maintain the dust suction effect.

3. Since the side plates 32 of the housing 3 extend downward and toward the body 2, respectively, the narrow passage area 41 of each suction passage 4 is smaller than the wide passage area 42, so that the flow guiding and suction efficiency can be improved.

4. When the air jet ports 218 are wavy and extend in the length direction, the range of air jetting can be increased, so that a larger range of dust is blown away, and the dust removal efficiency is increased.

5. The number of the through holes 226 of each louver 225 increases as the distance from the exhaust end 223 increases, so that the overall suction pressure in the upper suction chamber 221 is balanced.

6. When the length of body 2 surpasses 1 meter, will air feed tuber pipe 5 set up in the air feed end 216 that lower floor 21 corresponds, and will exhaust tuber pipe 6 set up in the exhaust end 223 that upper strata 22 corresponds can promote the effect of dust removal, clean air.

Therefore, the object of the present invention can be achieved.

The above description is only an example of the present invention, and the scope of the present invention should not be limited thereby, and the invention is still within the scope of the present invention by simple equivalent changes and modifications made according to the claims and the contents of the specification.
