Specifically, the water raising plate 54 projects from the outer wall of the cylindrical wall 533 of the suction pipe 53 to the outside away from the suction pipe 53, and has a circular flat plate shape disposed substantially in the horizontal direction. The pumping plate 54 may be provided with several blocks, and the pumping plates 54 are disposed parallel to and spaced apart from each other.

As described above, in the case where each group of the fine spray holes 534 includes two fine spray holes 534, the two fine spray holes 534 are oppositely disposed between the adjacent two of the pumping plates 54.

In this embodiment, the uppermost pumping plate 54 is formed integrally with the cylinder wall 533, whereby the other pumping plates 54 are detachably connected to the adjacent pumping plate 54 above. The connection mode can be realized by the technical scheme in the field such as arranging the embedded structure on the two water-raising plates 54 adjacent to each other. Of course, other water pumping plates 54 may be formed integrally with the cylinder wall 533.

In the present embodiment, in the case where the six fine spray holes 534 are provided as described above and the three groups of fine spray holes 534 are divided, the number of the lift plates 54 is four, the lift plates 54 are arranged to be spaced apart from each other in the vertical direction to form three intervals, and the three groups of fine spray holes 534 divided into the three groups are respectively provided in the three intervals. In an embodiment according to the present invention, the water plate is arranged in a horizontal ring shape coaxial with the rotation axis 52.

The first water blocking rib 43 extends in the inward surrounding direction of the wind guide plate 41 and is inclined upward. In addition, the position of the first water blocking rib 43 is set at the middle of the open hole 42 and is deviated to the upstream side of the rotation direction of the rotation shaft 52, for example, in the present embodiment, the rotation direction of the rotation shaft 52 is counterclockwise direction as viewed from the angle of fig. 7, that is, the end of the first water blocking rib 43 corresponding to the upstream side of the rotation direction of the rotation shaft 52 is the end positioned at the upper end of the first water blocking rib 43 with respect to the first water blocking rib 43, and therefore, the position of the first water blocking rib 43 is set at the middle of the open hole 42 and is deviated to the upper side as viewed from the angle of fig. 7.

The second water blocking rib 44 extends from an end of the first water blocking rib 43, which is located on the upstream side in the rotation direction of the rotating shaft 52, for example, in the present embodiment, the rotation direction of the rotating shaft 52 is counterclockwise as viewed from the angle of fig. 7, that is, for the first water blocking rib 43, the end of the first water blocking rib 43 corresponding to the upstream side in the rotation direction of the rotating shaft 52 is located on the upper end of the first water blocking rib 43 shown in fig. 7, and therefore, the second water blocking rib 44 extends from the end. Meanwhile, the second water bar 44 extends to the connecting air deflector 41 and extends along the opposite direction of the air deflector 41 to the opening 42, i.e., to the inner space of the air deflector 41. Thus, the first water-retaining rib 43 and the second water-retaining rib 44 are combined to form a shape like the numeral "7" from the perspective shown in fig. 7. The first and second water blocking ribs 43 and 44 are located at positions vertically above the water scooping plate 54.

A water guard plate 45 is provided in the internal space of the air guide portion 40. The water deflector 45 is plate-shaped and is disposed along the axial direction of the rotating shaft 52, and the water deflector 45 extends from the outside of the motor 51 to the position adjacent to the air deflector 41 and is located at the innermost position of the air guiding portion 40, i.e., at the opposite side of the open opening 42 based on the liquid crushing portion 50. The water guard 45 is disposed perpendicular to the plane of the opening 42.

In addition, in order to firmly mount the air deflector 41 inside the air treatment device, various support ribs, mounting structures, and the like are provided around the air deflector 41, which are general techniques in the art and will not be described herein.

The above is a detailed description of the main structure of the air treatment device. In addition, various functional units designed according to different product positioning, such as an air dehumidifying unit, an air guiding unit, a heat exchanging unit, a filtering unit, a sterilizing unit and the like, can be installed in the air processing device, and detailed descriptions of other functional units are omitted in the present invention.

Next, the air flow direction in the air treatment device will be described with reference to fig. 9. Fig. 9 is a side sectional view showing the flow of air in the air treatment device according to the present invention, the direction K of the flow of air being shown by the arrows.

The air outside the air processing apparatus is first sucked into the casing 10 from the air inlet 11 of the casing 10 by the driving of the blower unit (not shown), and then the air passes through the air conditioning heat exchanger 20 and the PTC heater 30 in order, and then enters the air guide portion 40 through the opening 42 of the air guide portion 40. Then, due to the blocking of the air deflector 41, the air only flows downward after impacting the air deflector 41, that is, the air deflector 41 can guide the air into the liquid breaking portion 50, and the air is prevented from directly blowing toward the air outlet 12 without passing through the liquid breaking portion 50. At this time, the air is mixed with the liquid particles finely divided by the liquid breaker 50 while passing through the position of the water lifting plate 54 of the liquid breaker 50, and then continuously flows into the water reservoir 60. Then, due to the obstruction of the stored liquid in the water storage portion 60, the air turns again and flows out through the outlet between the air deflector 41 and the water storage portion 60, completely leaves the liquid storage space 65 surrounded by the water storage portion 60, flows toward the air outlet 12 of the housing 10, and is finally discharged to the outside of the air treatment device through the air outlet 12.

Next, referring back to fig. 4 and 5, a mode of crushing and refining the liquid by the liquid crushing unit 50 according to the present invention will be described.

When the air treatment apparatus is operated, the motor 51 is powered on and rotates at a high speed, and the rotational motion is transmitted to the pumping plate 54 through the rotating shaft 52, so that the pumping plate 54 and the suction pipe 53 rotate at a high speed. At the same time, the water reservoir 60 is supplied with liquid to a water supply (not shown). Since the water suction port 531 at the lower end of the suction pipe 53 is immersed in the liquid stored in the water storage unit 60, the liquid in the water storage unit 60 can enter the hollow space of the suction pipe 53 through the water suction port 531 and rise up against the inner wall of the cylinder wall 533 of the suction pipe 53 by the centrifugal force generated by the high-speed rotation of the suction pipe 53. Meanwhile, the suction pipe 53 has a hollow structure in the shape of an inverted circular truncated cone, that is, the inner wall of the cylinder wall 533 is an inclined surface expanding upward, so that the liquid located on the inner wall of the cylinder wall 533 is less likely to fall down by the centrifugal force to move upward along the inclined surface more effectively.

Then, after the liquid in the water storage part 60 enters the inner wall of the cylinder wall 533 of the water suction pipe 53 through the water suction port 531, the liquid gradually moves upward along with the inclined wall of the inner wall to the position where the fine water spray hole 534 is provided at the upper part of the water suction pipe 53, and since the liquid without the support of the cylinder wall 533 passes through the fine water spray hole 534 immediately and is sprayed in the centrifugal direction and leaves the cylinder wall 533, the liquid thrown out of the fine water spray hole 534 is broken into fine particles. The degree of liquid breakup (degree of fineness) is influenced by the rotation speed of the suction pipe 53, the shape of the suction pipe 53, the size and position of the fine water spray holes 534, and the like, and those skilled in the art can design and adjust the above structure according to actual product requirements.

Then, part of the liquid particles thrown from the fine water spray holes 534 reaches the pumping plate 54 and adheres to the pumping plate 54. Since the pumping plate 54 and the suction pipe 53 rotate together at a high speed, the liquid particles attached to the plane of the pumping plate 54 continue to accelerate and are discharged in the centrifugal direction, and in this process, the liquid particles continue to be separated at a high speed to make the volume of the liquid particles finer, or the liquid particles are thrown out at a higher speed and hit the air deflector 41 or the water storage part side surface 62, so that the liquid achieves the effect of finer (atomization).

The liquid particles are eventually thrown off the splash plate 54 by the centrifugal force. On one hand, a part of the scattered liquid particles with smaller volume and lighter weight can be immediately mixed with air flowing through the periphery and discharged out of the liquid crushing part 50 along with the air flow; on the other hand, a part of liquid particles with large volume and large mass are difficult to mix in the air immediately, and are continuously thrown to the water storage part side surface 62 or the air deflector 41 and dispersed by colliding with the wall surface, so that the liquid particles are further micronized, and the liquid particles with further micronized volume and mass are reduced, so that the liquid particles can be mixed in the flowing air and discharged out of the liquid crushing part 50 along with the air flow; on the other hand, a part of the liquid having a larger volume or mass falls down to the liquid stored in the reservoir portion 60 due to gravity and is recovered. Thus, the function of humidifying air is realized.

Next, the operation of the water guard plate 45, the first water guard rib 43, and the second water guard rib 44 will be described with reference to fig. 10. Fig. 10 is a schematic diagram of a liquid particle splashing path of the present embodiment, and the liquid particle splashing path L and the motor rotation direction M refer to fig. 10.

Because the liquid crushing is operated in a high-speed rotation state, the mass and volume of the crushed liquid particles are different, and the shape of the water-board is different, the angle at which the liquid particles are finally thrown away from the water-board 54 is different, that is, the liquid particles can be splashed outwards from the direction from the obliquely upper side to the obliquely lower side. Meanwhile, as shown in fig. 10, the liquid particles are continuously splashed in the rotating direction by the inertial action in the rotating direction of the liquid breaking unit 50 during the splashing. Therefore, a part of the liquid particles splashed diagonally upward may pass through the open opening 42 to be splashed onto the PTC heater 30 or the air-conditioning heat exchanger 20 located beside the open opening 42, resulting in being damaged by moisture.

Thus, the provision of the water deflector 45 allows splashed liquid particles to strike the water deflector 45, thereby preventing the liquid particles from continuing to splash outside the opening 42. The liquid particles are accumulated on the water baffle 45 after being stopped by the water baffle 45, and the accumulated liquid particles drop to the water storage part 60 positioned below due to the action of gravity after reaching a certain weight.

On the other hand, the first and second water blocking ribs 43 and 44 are designed to further block more splashed liquid particles from splashing on the PTC heater 30 or the air-conditioning heat exchanger 20 beside the opening 42. Specifically, the first water-blocking rib 43 and the second water-blocking rib 44 both extend toward the liquid-breaking portion 50, that is, are close to the water-raising plate 54, and the water-raising plate 54 is located below the first water-blocking rib 43 and the second water-blocking rib 44 in the vertical direction, so that the liquid particles splashed from the water-raising plate 54 are more blocked by the lower side surfaces of the first water-blocking rib 43 and the second water-blocking rib 44, thereby further preventing the liquid particles from continuously splashing outside the opening 42.

Similarly, the first water blocking rib 43 is inclined upward in the direction of the liquid breaking portion 50, and when the extension length is constant, the liquid particles scattered from the obliquely downward direction can be more blocked.

The second water blocking rib 44 extends from the upstream end of the second water blocking rib 44 in the rotation direction of the rotation shaft 52, and can block more liquid particles flying toward the opening 42.

In view of the air deflector 41, the first water blocking rib 43 and the second water blocking rib 44 are disposed at the position of the open opening 42 of the air deflector 41, and the water blocking plate 45 is disposed at the inner position of the air deflector 41 opposite to the open opening 42, in other words, the water blocking plate 45 located at the opposite position can block liquid particles that are not blocked by the first water blocking rib 43 and the second water blocking rib 44, so that the position configuration can increase the capability of blocking splashed liquid particles, thereby further preventing the liquid particles from continuously splashing outside the open opening 42.

Compared with the prior art, the utility model has the advantages that the liquid is crushed by the liquid crushing part to be micronized, so that the air is fully contacted and moistened with the liquid, and the air humidifying effect is improved; by arranging the water baffle, splashed liquid particles can be hit on the water baffle, so that the liquid particles are prevented from continuously splashing to the outside of the opening, water mist crushed by the centrifugal water treatment module is prevented from splashing on an air treatment module such as an air heating module, and the air treatment module is prevented from being damaged on the basis of ensuring the miniaturization of the device; the liquid particles are accumulated on the water baffle after being blocked by the water baffle, and the accumulated liquid particles drop to the water storage part positioned below due to the action of gravity after reaching a certain weight, so that the practical liquid can be effectively circulated.

The above-mentioned embodiments only represent some embodiments of the present invention, and the description thereof is specific and detailed, but not to be construed as limiting the scope of the present invention. It should be noted that, for those skilled in the art, without departing from the spirit of the present invention, several variations and modifications can be made, which are within the scope of the present invention.
