A through hole 92 is provided on the surface of the slide plate 91. A resistance rod 93 is fixed to the inner side of the through hole 92. The end of the resistance rod 93 away from the through hole 92 extends into the arc-shaped groove 98, and the resistance rod 93 resists the inner wall of the arc-shaped groove 98. A rubber pad 94 is fixed to the top of the slide plate 91. The top of the connecting box 13 is rotatably connected to a gear 1 95. The top of the rotating rod 90 passes through the gear 1 95, and the rotating rod 90 is fixedly connected to the gear 1 95. The top of the connecting box 13 is rotatably connected to a gear 2 96, and the gear 2 96 meshes with the gear 1 95. A rocker 9 is fixed to the top of the gear 2 96. 7. The replacement component 9 also includes a limiter 99. The rocker 97 is rotated clockwise, and the gear 2 96 drives the two sets of gears 1 95 to rotate. The two sets of rotating rods 90 rotate in opposite directions, and the arc-shaped slide groove 98 moves with the contact rod 93, driving the slide plate 91 and the rubber pad 94 to move. One set of slide plates 91, through holes 92, contact rods 93, and rubber pads 94 move downward, and one set of slide plates 91, through holes 92, contact rods 93, and rubber pads 94 move upward. The downward rubber pad 94 is separated from the air outlet of the Y-shaped tube 7, and the upward rubber pad 94 blocks the other air outlet of the Y-shaped tube 7.

A T-shaped plate 992 is fixed on the end of the spring 991 away from the fixing plate 990. The T-shaped plate 992 is slidably connected to the top of the connecting box 13. When the T-shaped plate 992 is released, the spring 991 drives the T-shaped plate 992 to enter between the teeth of the gear 2 96 to limit the gear 2 96, thereby preventing accidental rotation and affecting the use.

[0024] There are two sets of slide plates 91, through holes 92, abutment rods 93, and rubber pads 94, and the two sets of slide plates 91, through holes 92, abutment rods 93, and rubber pads 94 are staggered and symmetrically arranged with the center line of the connection box 13 as the symmetry axis. There are two sets of gears 1 95, rotating rods 90, and arc-shaped slide grooves 98, and the two sets of gears 1 95, rotating rods 90, and arc-shaped slide grooves 98 are symmetrically arranged with the center line of the connection box 13 as the symmetry axis. When the gear 2 96 rotates, the two sets of gears 1 95 can rotate simultaneously. Rotate and cooperate with the arc-shaped slide groove 98, so that the two groups of slide plates 91, the through hole 92, the resistance rod 93, and the rubber pad 94 move relative to each other. The rubber pad 94 is located just below the outlet of the Y-shaped tube 7, so that when the rubber pad 94 moves up, it can block the Y-shaped tube 7. A accommodating cavity 3 is provided inside the drying box 1, and an electric heating tube 4 is arranged inside the accommodating cavity 3. The electric heating tube 4 can be used for drying.

[0025] A stabilizing plate 14 is fixed to the inner wall of the connecting box 13, and a fixing frame 8 is fixed to the surface and inner wall of the stabilizing plate 14 and the connecting box 13. An activated carbon filter element 10, a HEPA filter element 11, and a molecular sieve filter element 12 are placed in the fixing frame 8 respectively. The fixing frame 8 and the activated carbon filter element 10, the HEPA filter element 11, and the molecular sieve filter element 12 are each provided with two groups, and the two groups of activated carbon filter elements 10, HEPA filter elements 11, and molecular sieve filter elements 12 are symmetrically arranged with the center line of the connecting box 13 as the symmetry axis. A sealing door 17 is connected to the surface of the connection box 13, and an observation window 18 is opened on the surface of the sealing door 17. A suction fan 15 is fixed to the back of the connection box 13, and the suction end of the suction fan 15 passes through the connection box 13. An air outlet pipe 16 is fixed to the suction end of the suction fan 15. Two groups of suction fans 15 and air outlet pipes 16 are provided, and the two groups of suction fans 15 and air outlet pipes 16 are symmetrically arranged with the center line of the connection box 13 as the symmetry axis, which is convenient for alternating use and can be replaced without shutting down for drying.

[0026] When it is necessary to dry the printed board, place the board between the placement racks 5, close the box door 2, turn on the electric heating tube 4 to perform the drying operation, and turn on the suction fan 15 at the same time, so that the exhaust gas generated by the drying enters the connection box 13 through the connecting pipe 6 and the Y-shaped pipe 7, and is filtered through one of the two groups of activated carbon filter elements 10, HEPA filter elements 11, and molecular sieve filter elements 12, and is discharged through the air outlet pipe 16. When the use time is long, one group of activated carbon filter elements 10 and HEPA filter elements 11 need to be replaced. When the core 11 and the molecular sieve filter element 12 are in contact, the T-shaped plate 992 is pulled to make the T-shaped plate 992 away from the gear 2 96, and the rocker 97 is turned clockwise, so that the gear 2 96 drives the two sets of gears 1 95 to rotate, thereby making the two sets of rotating rods 90 rotate in opposite directions. At this time, the arc-shaped slide groove 98 moves with it, driving the resistance rod 93 to move, thereby driving the slide plate 91 and the rubber pad 94 to move, so that one set of slide plates 91, the through hole 92, the resistance rod 93, and the rubber pad 94 move downward, and one set of slide plates 91, the through hole 92, the resistance rod 93, and the rubber pad 94 move downward. The hole 92, the abutment rod 93, and the rubber pad 94 move downward, and the downward rubber pad 94 is separated from the air outlet of the Y-shaped tube 7. At the same time, the personnel turns on another set of suction fans 15, and the upward rubber pad 94 blocks the other air outlet of the Y-shaped tube 7, loosens the T-shaped plate 992, and allows the T-shaped plate 992 to enter between the teeth of the gear 2 96 to limit the gear 2 96, so as to prevent accidents from causing self-rotation and affecting use. At this time, the corresponding set of suction fans 15 that need to be replaced, the HEPA filter element 11, and the molecular sieve filter element 12 are closed. At this time, the personnel can open the corresponding sealing door 17 that needs to be replaced, extract the activated carbon filter element 10, the HEPA filter element 11, and the molecular sieve filter element 12, and clean or replace them, so that they can be replaced without stopping drying, thereby improving the drying efficiency. When it needs to be replaced again, the rocker 97 can be turned counterclockwise to repeat the above steps to replace it again. When replacing, the personnel can observe the position of the rubber pad 94 through the observation window 18, which is convenient for the personnel to stop turning the rocker 97.

[0027] The above generally describes the present invention in detail, but it is obvious to a person skilled in the art that some modifications or improvements can be made to the present invention. Therefore, modifications or improvements that do not deviate from the spirit of the present invention are within the scope of protection of the present invention.
