[0037] In this embodiment, the air curtain fan mounting assembly 1 is used to install the air curtain fan 5, so that the air curtain bracket 11, the cyclone seat 12, and the air curtain fan 5 together form an air curtain assembly. The air curtain assembly can be installed on the top plate 21 of the main body of the smoke machine. The top plate 21 is provided with an air curtain exhaust port 211. The surface of the top plate 21 with at least the air curtain exhaust port 211 is raised upward relative to the other parts of the top plate 21 to form a raised portion. The air curtain bracket 11 is located on the top plate 21, and the clearance port 111 avoids the raised portion. The cyclone seat 12 is located on the air curtain bracket 11. The cyclone seat 12 is provided with an air curtain duct 121 communicating with the air curtain exhaust port 211. The air curtain fan 5 is located on the cyclone seat 12, and the air outlet of the air curtain fan 5 faces the air curtain duct 121.

[0038] The raised portion is formed on the upper plate surface of the top plate 21, and the lower plate surface of the top plate 21 is concave corresponding to the raised portion, and the air curtain exhaust port 211 is arranged in the cavity, and the air curtain exhaust port 211 penetrates the upper plate surface and the lower plate surface of the top plate 21. The air curtain assembly is installed on the upper plate surface of the top plate 21 and located at the air curtain exhaust port 211, wherein the air curtain support 11 is used to support the cyclone seat 12 and the air curtain fan 5 above the air curtain exhaust port 211. The air curtain support 11 is connected to the plate surface of the top plate 21 around the raised portion, and the raised portion is located in the avoidance port 111, so that the air curtain support 11 can avoid the raised portion through the avoidance port 111 and be connected with the top plate 21, so as to realize the stable installation of the air curtain support 11 on the top plate 21. After the air curtain support 11 is connected to the top plate 21, the cyclone seat 12 is installed on the air curtain support 11, and then the air curtain fan 5 is installed on the cyclone seat 12, so that the stable installation of the air curtain assembly as a whole on the top plate 21 can be realized. The avoidance port 111 can also communicate the air curtain air duct 121 of the cyclone seat 12 with the air curtain exhaust port 211, so that the airflow blown by the air curtain fan 5 to the air curtain air duct 121 can flow to the air curtain exhaust port 211 through the avoidance port 111, and then flow to the lower part of the top plate 21 to form an air curtain. By arranging the avoidance port 111 on the air curtain support 11, the installation of the raised portion on the top plate 21 on the air curtain support 11 can be avoided, so as to improve the overall installation convenience of the air curtain assembly.

[0039] The number of air curtain exhaust ports 211 on the top plate 21 can be two, and the two air curtain exhaust ports 211 are arranged in the cavity and are arranged in the length direction of the cavity. The number of air curtain assemblies is two, and the two air curtain assemblies are respectively installed on the top plate 21 corresponding to the two air curtain exhaust ports 211.
