The invention discloses a highly-environment-friendly coating spray head for furniture. The highly-environment-friendly coating spray head comprises a spherical coating spray ball of a hollow structure internally, the side wall of the coating spray ball is connected with two nozzles, the include angle between the two nozzles is 15-20 degrees, the distance between the ends, connected with the sidewall of the coating spray ball, of the two nozzles is 5-8mm, the side wall, away from the nozzles, of the coating spray ball is connected with a feeding pipe, the nozzles are in a circular truncated cone shape, the liquid drainage ends of the nozzles are provided with multiple liquid spray holes, the interiors of the liquid spray holes are provided with cavities in a circular truncated cone shape,the inner wall of the liquid drainage end of each liquid spray hole is evenly provided with triangular convex teeth in the circumferential direction, the outer walls of the liquid drainage ends of the nozzles are sleeved with funneled shield covers, openings of the shield covers are covered with spray insulation nets, and the spray insulation nets and the shield covers cover the liquid drainage ends of the nozzles. By means of the spray head, uniform spraying can be carried out, the spraying quality is improved, a good protection effect can be achieved on the spray head and the furniture surface, and the problem that the spray head is polluted by collision between the spray head and the furniture surface is avoided.
