The application provides a mixer of a U-shaped post-processing device, which optimizes the structure of the mixer, further prolongs the mixing stroke of the mixer, accelerates the rotating speed of the airflow, makes the urea and ammonia fully react, and reduces the risk of urea crystallization; an air inlet guide plate is arranged vertically at an air inlet; the airflow entering from the air inlet is divided into two airflows by the air inlet guide plate and enters the airflow channel between the inner cylinder and the outer cylinder; a channel separation plate is arranged in the airflow channel; the air inlet guide plate extends into the airflow channel; the air inlet guide plate and the channel separation plate separate the airflow channel into two parts; the inner cylinder is provided with a rotating flow fin, and a gap is left between the rotating flow fin and the outer cylinder; the inner cylinder is provided with an airflow inlet corresponding to the rotating flow fin; the inner cylinder is provided with a urea airflow inlet corresponding to the channel separation plate; and the outer cylinder is provided with a urea nozzle facing the urea airflow inlet.

This application provides a pot support and a cooktop. The pot support includes a pot frame body and a pulsating heat pipe. The pot frame body is annularly arranged and has an enclosing combustion chamber for housing a burner and allowing the burner's flame to pass through. The pot frame body has a preheating chamber and a secondary air flow channel connected within it. The secondary air flow channel transports secondary air flowing through the preheating chamber to the burner. The pulsating heat pipe is disposed within the pot frame body and has an evaporation end located near the combustion chamber and a condensation end located away from the combustion chamber. The condensation end is located within the preheating chamber, and the inside of the pulsating heat pipe is sealed and filled with a heat exchange medium. The heat released from the condensation end is used to heat the secondary air in the preheating chamber. At least a portion of the wall surface of the secondary air flow channel is formed by the top surface of the pot frame body. This technical solution enables waste heat recovery from the pot support and preheating of the combustion air, effectively improving the heat utilization efficiency of the cooktop.
