Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.
As shown in fig. 1-6, a sealing structure of an air filter alarm switch comprises an upper shell 1 and a lower shell 2, wherein the upper shell 1 and the lower shell 2 are connected by a buckle, an upper annular plate 3 is arranged in the upper shell 1, a lower annular plate 4 is arranged in the lower shell 2, a gasket groove 5 is arranged at the top end of the lower annular plate 4, a sealing ring is arranged in the gasket groove 5, and the upper annular plate 3 is clamped in the gasket groove 5 of the lower annular plate 4 while the upper shell 1 and the lower shell 2 are connected by the buckle; two terminals 6 which are integrally molded are arranged in the lower shell 2, the lower parts of the terminals 6 are coated with injection molding block bodies 7 which are respectively connected with the lower annular plate 4 and the bottom of the lower shell 2, the top ends of the injection molding block bodies 7 are arranged in a glue pouring groove 8 in the upper shell 1, rectangular blocks 10 with rectangular through holes 9 in the middle are arranged in the glue pouring groove 8, the number of the rectangular blocks 10 is 2, the rectangular through holes 9 for the terminals 6 to penetrate through are respectively arranged, a joint connecting pipe 11 which is communicated with the glue pouring groove 8 through the rectangular through holes 9 is arranged outside the upper shell 1, and the terminals 6 penetrate through the rectangular through holes 9 and extend into the joint connecting pipe 11; and a glue filling opening 12 corresponding to the glue filling groove 8 is formed in the bottom of the lower shell 2.
