The invention discloses a primary and secondary fusion ring network device which comprises a bottom box. The top of the bottom box is fixedly connected to a ring network device, and the back of the inner wall of the bottom box is fixedly connected to a motor. An output end of the motor is fixedly connected to a round disc. The top of the front side of the round disc is fixedly connected to a transmission rod, and the surface of the transmission rod is slidingly connected to a movement frame. Two sides of the movement frame are fixedly connected to cross bars, and the bottoms of two sides of the inner wall of the bottom box are fixedly connected to sliding rods. Through the combined use of the bottom box, the ring network device, the motor, the round disc, the transmission rod, the movementframe, the cross bars, the sliding rods, sliding rings, a fan, suction heads, telescopic hoses and exhaust pipes, the problem that an existing primary and secondary fusion ring network device does not have a heat radiation problem is solved, the primary and secondary fusion ring network device of the invention has the advantage of heat radiation and is convenient for a user to use, and the service life of the primary and secondary fusion ring network device is improved.
