It should be noted that the mode that water in multiple water channels 321 hits have it is a variety of, such as by multiple water channels 321 The aqueous phase of adjacent two water channel 321 is mutually hit, for another example by the water of multiple water channels 321 positioned at side and by positioned at another relative The mutually shock etc. of the aqueous phase of multiple water channels 321 of side, is not just listed one by one herein.

In an embodiment of the present utility model, Fig. 4 is refer to, there is water side to shock section 32 in multiple water channels 321 Multiple first water channel 321a for being obliquely installed of side and water side to hit 32 another opposite side of section be obliquely installed it is multiple Second water channel 321b, that is to say, that any first water channel 321a and any second water channel 321b is in splayed, and this allows for passing through Multiple first water channel 321a water can be with mutually being hit by multiple second water channel 321b aqueous phase, and then forms spray.

Obviously, in another embodiment of the present utility model, Fig. 5 is refer to, can also will pass through adjacent two water channel 321 Aqueous phase is mutually hit.Specifically, the water channel 321 of arbitrary neighborhood two forms the first flow impact group, and every 1 the in multiple water channels 321 The water side of a water channel 321 in one flow impact group is obliquely installed to the water side of another water channel 321.It is that is, each Two water channels 321 in first flow impact group are set in splayed, and this allows for equal by the water of every one first flow impact group Spray can be produced, spray can be formed by so allowing for shock section 32 many places, and then can effectively expand cleaning area Area.

In addition, in an embodiment of the present utility model, Fig. 6 is refer to, can also will be adjacent two-by-two in multiple water channels 321 Three water channels 321 form the second flow impact group.Specifically, the water channel 321 among three water channels 321 is internal water main 321c, it is extended along the bearing of trend for hitting section 32, and the water channel 321 positioned at internal water main 321c sides is the 3rd water channel 321, the water channel 321 positioned at internal water main 321c opposite sides is the 4th water channel 321e, and the water side of the 3rd water channel 321 to by Nearly 4th water channel 321e direction tilts, and the 4th water channel 321e water side tilts to close to the direction of the 3rd water channel 321.Also It is to say, internal water main 321c, the 3rd water channel 321 and the 4th water channel 321e form " individual " set up of character patt ern, when water passes through the second water When flowing shock group, mutually hit by the aqueous phase of the 3rd water channel 321 and the 4th water channel 321e, and pass through internal water main 321c water The intersection for flowing through the 3rd water channel 321 and the 4th water channel 321e water straight, this allows for three strands of water along three differences Direction converge and mutually hit, and then produce bigger spray.

In order to ensure that the flow velocity of the water by water channel 321 is sufficiently large, in an embodiment of the present utility model, each water channel 321 width is gradually reduced from its water inlet end to its water side.It is understood that fluid enters from a larger runner of width When entering runner less to a width, its space flowed reduces, and then to be squeezed during its flowing, and extruding is more severe, Then the speed of fluid is increased more.After this allows for each water channel 321 of aquaporin, its speed can be improved, so Ensure that has sufficiently large speed by the water of each runner, and then ensure that the water mutually hit can produce spray.

Obviously,, will in another implementation of the present utility model in order to ensure that the flow velocity of the water by water channel 321 is sufficiently large Hit section 32 and be arranged on air-treatment air channel 13 at air outlet 12.It should be noted that the sky in air-treatment air channel 13 After the acceleration of wind wheel 20, its flowing velocity greatly increases gas, will hit section 32 and be arranged on the neighbour of air-treatment air channel 13 At nearly air outlet 12 so that not only accelerated by the water for each water channel 321 for hitting section 32 by the effect of water channel 321, also simultaneously The effect for the air that can be flowed second accelerates, this allow for it is sufficiently large by the flow velocity of the water of each water channel 321, and then It ensure that the water mutually to cross can produce violent shock and produce spray and steam, the spray splash can then be used for cleaning Air, which improves the cleanliness factor of air；The steam of floating then can be with air together big flowing and from the row of air outlet 12 Go out, which improves the humidity of air.
