In the spray head of above-mentioned deduster, be fixed with the adapter that communicates with the water flowing straight hole on the described sprayer body.Spray head directly is communicated with water inlet pipe by taking over, convenient water inlet.

In the spray head of above-mentioned deduster, be connected with sprinkler cap on the described sprayer body.Easy to process for whole spray head not only like this, and have dust to stop up can to open sprinkler cap when spray head stops up and clear up.

In the spray head of above-mentioned deduster, hexagonal draw-in groove in having on the described sprinkler cap.

In the spray head of above-mentioned deduster, has circular saw on the edge of described sprinkler cap.In the time will opening or screw sprinkler cap, in being stuck in, operates in the hexagonal draw-in groove by available instrument, and also can directly be stuck in circular saw in addition and operate with hand.

Compared with prior art; advantage of the present utility model is because water inlet straight hole and spout all have eccentric structure; therefore water enters the inner chamber of sprayer body after after the rotation; droplet from the spout ejection is tiny again; improved the uniformity of particle diameter; the spray effect of the stable fine droplet of generation, dust in the air-flow and solid particle can fully be adsorbed, good dedusting effect.On the other hand, this showerhead configuration is simple, is difficult for causing delivery port to stop up, and has reduced manufacturing procedure and difficulty, has reduced production cost.
