[0077] Embodiment 9

[0078] like Figure 1-21 As shown, the exhaust valve includes a valve bonnet 50, a ventilation hole 51, a spring 52, a spring bracket 53, a limit tube 54, and a center screw 55. The valve bonnet 50 slides on the outer wall of the exhaust pipe 45. The valve bonnet 50 is provided with a ventilation hole 51. The valve bonnet 50 is fixed to one end of the spring 52. The other end of the spring 52 is fixed to the spring bracket 53. The spring bracket 53 is slidably connected to the limit tube 54. The limit tube 54 is fixed in the exhaust pipe 45.

[0079] The air inlet valve includes a valve bonnet 2 56, a ventilation hole 2 57, a spring 4 58, a spring bracket 2 59, a limit tube 2 60, and a center screw 2 61.

[0080] The working principle of the above technical solution is as follows: when the hot air pressure in the closed space formed by the drying mechanism housing 24, the collecting cover 44 and the exhaust pipe 45 is greater than the preset pressure value, the hot air pushes the valve cap 50 to move outward, driving the spring 3 52 to be stretched, and the ventilation hole 51 moves to the outside of the pipe wall of the exhaust pipe 45, and the hot air in the closed space is discharged to the outside through the ventilation hole 51, thereby reducing the air pressure in the closed space.

[0081] When the hot air pressure in the enclosed space formed by the drying mechanism shell 24, the collecting hood 44 and the exhaust duct 45 is less than the preset pressure value, the outside air pushes the valve cap 2 56 inward, driving the spring 4 58 to be compressed, and the air exchange hole 2 57 moves to the inner side of the tube wall of the exhaust duct 45. The outside air enters the enclosed space from the air exchange hole 2 57, thereby increasing the air pressure in the enclosed space. When the air pressure in the enclosed space increases to the preset pressure value, the valve cap 2 56 is restored to its original position under the action of the restoring elastic force of the spring 4 58, and the rotating center screw 2 61 drives the spring bracket 2 59 to move in the limit tube 2 60, thereby changing the length of the spring 4 58 in the initial state, thereby changing the preset pressure value.

[0082] It is to be understood that the present invention is described by some embodiments, and it is known to those skilled in the art that various changes or equivalent substitutions may be made to these features and embodiments without departing from the spirit and scope of the present invention. In addition, under the teachings of the present invention, these features and embodiments may be modified to adapt to specific circumstances and materials without departing from the spirit and scope of the present invention.
