Further, the negative ion generator 35 is arranged such that the releasing tip 37 is disposed in the flow-through space a318 having a small cross-sectional area in a direction perpendicular to the axis of the accelerating channel 36, the releasing tip 37 generates negative ions in the flow-through space a318, the negative ions in the flow-through space a318 are rich and occupy a small space, the negative ion concentration in the flow-through space a318 is high due to the blocking of the flow guide plate 316, only a small amount of negative ions enter the flow-through space B319 in which the releasing tip 37 is not disposed along the edge of the flow guide plate 316, i.e., the opening of the flow-through space a318, because negative ions cannot be generated in the flow-through space B319 in which the releasing tip 37 is not disposed, the negative ion concentration in the flow-through space B319 is low, the releasing tip 37 is disposed such that an air flow having a high negative ion concentration and an air flow having a low negative ion concentration are formed in the accelerating channel 36, and the releasing tip 37 is disposed in the flow-through space a318 having a small cross-sectional area, the air flow with higher negative ion concentration in the accelerating flow channel 36 is smaller than the air flow with lower negative ion concentration, the quantity of negative ions consumed by the small flow space when the air flow with higher negative ion concentration flows in the accelerating flow channel 36 is less, and the flow space of the air flow with lower negative ion concentration when the air flow with lower negative ion concentration flows in the accelerating flow channel 36 is larger, so that the air outlet part 312 has enough air outlet quantity, when the air flow with higher negative ion concentration flows out of the accelerating flow channel 36, because the constraint of the guide plate 316 is not existed, the negative ions with higher concentration can enter the air flow with lower negative ion concentration, thereby not only ensuring enough flow speed and air outlet quantity, but also ensuring the negative ion concentration flowing out of the negative ion air purification device 31, and further improving the purification effect of the negative ion air purification device 31.
In a preferred embodiment, in addition to the above-described embodiment, the inner surface of the acceleration channel 36 is smooth. The accelerating flow channel 36 with the smooth inner surface enables air passing through the accelerating flow channel 36 to be smoother, prevents the inner surface of the accelerating flow channel 36 from being rough and increases the resistance of air circulation, enables the air to pass through the accelerating flow channel 36 more quickly, reduces the accumulation of dust in the accelerating flow channel 36 due to the smooth inner surface, and enables the accelerating flow channel 36 to be kept clean as much as possible in the using process.
In a preferred embodiment, in addition to the above-mentioned embodiment, a filter 321 is further provided on the street lamp air inlet 39. The filter screen 321 can filter large particles in the air passing through the filter screen, the filter screen 321 is arranged on the street lamp air inlet portion 39, so that the quality of the air entering the street lamp flow channel 320 is further improved, and the air with higher quality flowing out from the street lamp air outlet portion 310 enters the anion air purification device 31 in the following process, so that the consumption of anions in the anion air purification device 31 is reduced, and meanwhile, a cleaner environment can be kept in the anion air purification device 31.
In a preferred embodiment, in addition to the above-mentioned embodiment, a fixing bracket 322 is further provided on the negative ion air purification device 31, and the fixing bracket 322 connects the negative ion air purification device 31 and the negative ion air purification street lamp assembly 32. Adopt fixed bolster 322 to connect anion air purification device 31 and anion air purification street lamp subassembly 32, make the stability of anion air purification device 31's installation improve.
The above embodiments are only used to illustrate the present invention and not to limit the technical solutions described in the present invention, and although the present invention has been described in detail in the present specification with reference to the above embodiments, the present invention is not limited to the above specific embodiments, and therefore, any modifications or equivalents of the present invention may be made; all such modifications and variations are intended to be included herein within the scope of this disclosure and the appended claims.
