The relatively clean air filtered by the water storage area 13 is secondarily filtered by the filter 2 and then discharged from the air outlet 12.

The embodiment of the utility model provides a dust catcher sets up water storage district 13 through the bottom at casing 1, makes inspiratory air carry out water filtration at water storage district 13 to filter the dust particle of minor diameter earlier, then filter 2 filtration again. Therefore, the HEPA with lower grade can be adopted, and the cost is reduced; and because the high-grade HEPA is not needed, the suction performance of the whole machine is not influenced. In addition, the fan 3 is installed at the air outlet 12, that is, the fan 3 is located at the downstream of the filter 2 along the air flow direction, so that the clean air filtered by the water and the filter passes through the fan 3, thereby reducing the damage of the dust particles to the fan blade.

Because the air gets into water storage district 13 under the suction effect, can make the water in the water storage district 13 produce boiling phenomenon, in order to avoid sputtering filter 2 at this in-process normal water, cause the damage to filter 2, the embodiment of the utility model provides a dust catcher still includes first breakwater 5,

5 and 1 fixed connection of casing, and first breakwater 5 has the airflow channel who communicates water storage district 13 and air outlet 12. Wherein, fan 3 accessible support and 1 fixed connection of casing, first breakwater 5 and this support fixed connection, perhaps can dismantle to be connected if through bolted connection, perhaps joint etc.. After a part of dust particles in the air are mixed with the water in the water storage area 13, the formed relatively clean air can escape from the water, and the escaped air passes through the first water baffle 5 through the airflow channel under the suction action of the fan 3 and flows to the filter 2. Wherein, the air flow channel is also a water return channel, even if the water in the water storage area 13 passes through the first water baffle 5, the water can also flow back to the water storage area through the air flow channel.

The first water baffle 5 may have various structures, for example, the first water baffle 5 is a planar plate-shaped structure with a certain thickness, a plurality of curved air channels are arranged in the first water baffle, and air escaping from the water storage area 13 passes through the plurality of curved air channels under the suction effect of the fan 3. For another example, as shown in fig. 2, which is a schematic structural view of the first water baffle according to the embodiment of the present invention, as shown in fig. 3, which is a partial enlarged view of the portion a in fig. 1, the first water baffle 5 includes a plurality of annular flaps 52, the plurality of annular flaps 52 are coaxially distributed along the radial direction, the annular flaps 52 include an upper horizontal plate 521, a lower horizontal plate 522, and a riser 523 connecting the upper horizontal plate 521 and the lower horizontal plate 522, and the riser 523 and the lower horizontal plate 522 of the inner annular flap 52 and the riser 523 and the upper horizontal plate 521 of the outer annular flap 52 adjacent to the inner annular flap 52 form the airflow channel 51.

Specifically, as shown in fig. 3, a first gap exists between the lower transverse plates 522 of two adjacent annular flaps 52, a second gap exists between the upper transverse plates 521 of two adjacent annular flaps 52, and the first gap and the second gap are staggered. Through the folded airflow channel formed between the annular folding plates 52, water splashed in the water storage area 13 can be blocked by the upper transverse plate 521 even if passing through the first gap, so that the water quantity passing through the second gap is reduced to a greater extent, and therefore water splash splashed in the water storage area 13 is effectively blocked. Meanwhile, the flow area of the folded airflow channel 51 formed among the plurality of annular folded plates 52 is large, so that the resistance of the first water baffle 5 to the airflow can be reduced to ensure the suction performance of the whole machine, and the water flowing through the second gap can flow back to the water storage area 13 quickly.

In this embodiment, the specific form of the upper horizontal plate 521 is not particularly limited as long as the water passing through the first gap can be blocked to a certain extent. For example, the upper cross plate 521 may be a flat plate structure; for example, the upper horizontal plate 521 has a curved surface structure protruding in the air flow direction, or the upper horizontal plate 521 has a flat plate structure and a downward bent portion 524 is provided at an end side of the flat plate structure, so that the water hitting the upper horizontal plate 521 can be partially blocked from being splashed around, and the amount of water passing through the second gap can be reduced. The vertical plate 523 may be disposed in a vertical direction, or disposed at a certain inclination angle, which is not specifically limited in this embodiment. The mutual connection of the upper horizontal plate 521, the vertical plate 523 and the lower horizontal plate 522 is smoothed. The plurality of annular flaps 52 may be connected together by a plurality of annularly distributed webs 57.

The area formed by the surrounding of the annular side plate 53 and the base plate 58 is a dust-water mixing area 131, the dust-water mixing area 131 is positioned right above the water outlet 41, and the airflow channel surrounds the dust-water mixing area 131. The area of the water storage area 13 surrounding the dust-water mixing area 131 is a water body flat area 132. The air sucked from the air inlet 11 is ejected from the water outlet 41 of the water guide pipe 4 in a fountain-like manner at a high speed, and at this time, the air and water mixed with the dust particles collide with the base plate 58 and the annular side plate 53 thereon at a high speed, so that the dust particles and the water are fully mixed and dissolved in the water body as much as possible. The water flow rate to the water flat 132 is reduced and relatively clean air escapes from the water and flows through the air flow passage in the first breakwater 5 to the filter 2 under the suction of the fan 3.

In order to further guarantee that the water of water storage district 13 does not contact with filter 2, guarantee filter 2's dry environment, it is further, the embodiment of the utility model provides a dust catcher still includes second breakwater 6, and second breakwater 6 is installed between first breakwater 5 and filter 2, forms the second breakwater protective screen between water storage district 13 and the filter 2, and second breakwater 6 mainly used blocks through 5 water of first breakwater and the contact of filter 2. The second water baffle 6 is connected with the first water baffle 5, and the first water baffle and the second water baffle can be fixedly connected or detachably connected, such as through bolt connection or clamping connection. As shown in fig. 2 and 3, the base plate 58 of the first water baffle 5 is provided with a plurality of fastening holes 56, the second water baffle 6 is provided with fasteners 63 engaged with the fastening holes 56, and the first water baffle 5 and the second water baffle 6 are fastened by the fastening holes 56 and the fasteners 63.

Specifically, the second water deflector 6 is provided with an inclined surface 61, and the inclined surface 61 is used for guiding the air passing through the air flow channel 51 of the first water deflector 5 and the gap between the first water deflector 5 and the inner wall of the housing 1 to the direction of the air outlet 12. The inclined surface 61 is located above the airflow passage 51, for example, the inclined surface 61 is gradually close to the inner wall of the housing 1 from bottom to top, and a gap exists between the inclined surface 61 and the inner wall of the housing 1. The air passing through the air flow path 51 is guided by the inclined surface 61 so that the air passes through the second baffle 6 from a gap between the inclined surface 61 and the inner wall. For example, as shown in fig. 1, the inclined surface 61 is an annular conical surface tapering from top to bottom, the annular conical surface is located right above the airflow passage of the annular flap 52, and the bottom end of the annular conical surface is closed, so that a larger area of water is blocked. Of course, the inclined surface 61 may be gradually separated from the inner wall of the housing 1 from bottom to top, the bottom end of the inclined surface is connected to the inner wall of the housing 1 in a sealing manner, and a gap exists between the top end of the inclined surface 61 and the adjacent component.

Further, the filter 2 is located on a side of the inclined surface 61 away from the inner wall of the housing 1. For example, when the inclined surface 61 is an annular conical surface, the filter 2 is located inside a cone of the annular conical surface, so that the installation space can be saved, and the overall volume of the dust collector can be reduced. Wherein, the inclined surface 61 is fixed with a baffle plate 64 on the side away from the inner wall of the housing 1, and the setting height of the baffle plate 64 is not lower than the setting height of the filter 2, so as to block the water passing through the second baffle plate 6 from flowing to the bottom of the inclined surface 61, and further ensure the drying working environment of the filter 2.
