More effectively, the air inlet assembly 160 is arranged near the first fan 170, so that the distances between the air inlet assembly 160 and the first fan 170 and between the heating assembly 150 and the first fan 170 are equal, even the air inlet assembly 160 is closer to the first fan 170, the suction force of the first fan 170 on the air inlet assembly 160 is increased, more external air is introduced, and therefore, the circulation heating is fully performed, the glue content of the circulation air is reduced, and the glue discharging performance is improved.

More particularly, according to the utility model, the air intake assembly 160 is disposed near the first fan 170, so that the distances between the air intake assembly 160 and the first fan 170 and the heating assembly 150 are approximately the same in structural position, thereby shortening the length of the third channel 140, reducing heat loss, and making the structure of the glue discharging box more compact.
