Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] Reference Figure 1 , Figure 2 and Figure 3 The utility model provides an embodiment: a multi-layer oven, including a box body 1, an air inlet pipe 6 is fixedly connected to the top of the box body 1, a dustproof net 8 is fixedly connected to the inner side of the air inlet pipe 6, a fan 7 is arranged on the inner side of the air inlet pipe 6, a hollow box 9 is fixedly connected to the inner top of the box body 1, the bottom end of the air inlet pipe 6 is fixedly connected to the inside of the hollow box 9, heaters 10 are fixedly connected to the inside of the hollow box 9 on both sides, air outlet pipes 11 are fixedly connected to the bottom of the hollow box 9 on both sides, and air outlets 12 are arranged on the outside of the air outlet pipes 11. The outside of the tube 11 is fixedly connected to a support plate 13, and the support plates 13 are fixedly connected to both sides of the inside of the box body 1. The bottom end of the air outlet pipe 11 is fixedly connected to the inner bottom of the box body 1, and the top of the support plate 13 is fixedly connected to a plug rod 15. A bearing assembly is arranged on the top of the support plate 13, and the bearing assembly includes a placement plate 14. The placement plate 14 is arranged on the top of the support plate 13, and a socket 16 is opened on the top of the placement plate 14. The inside of the socket 16 is slidably connected to the plug rod 15, and a ventilation hole 17 is opened on the top of the placement plate 14.

[0025] The air inlet pipe 6 is used for the fan 7 to inhale external air flow, and the dustproof net 8 is used to filter dust and impurities. The fan 7 is driven to blow away the hot air flow generated by the heater 10 inside the hollow box 9, and the hot air flow is blown out through the air outlet 12 on the air outlet pipe 11, and evenly blows toward the objects to be dried on the placement plate 14. The placement plate 14 is engaged with the insertion rod 15 on the support plate 13 through the internal plug hole 16, and the ventilation hole 17 is used for ventilation.

[0026] Reference Figure 4 and Figure 5 A ventilation pipe 18 is fixedly connected to the inner bottom of the box body 1, the outside of the ventilation pipe 18 passes through the box body 1, a valve 19 is fixedly connected to the outside of the ventilation pipe 18, a recovery box 20 is provided at the bottom of the ventilation pipe 18, a delivery pipe 21 is fixedly connected to the outside of the ventilation pipe 18, a mounting plate 22 is fixedly connected to the inner side of the delivery pipe 21, a through hole 23 is opened inside the mounting plate 22, the delivery pipe 21 is fixedly connected to the inner side of the through hole 23, a slot 24 is opened inside the mounting plate 22, a dust removal net 25 is provided inside the mounting plate 22, and the dust removal net 25 is slidably connected to the slot 24.

[0027] After drying is completed, the hot air inside the box 1 is discharged through the ventilation pipe 18. The valve 19 is used to open and close the ventilation pipe 18. The ventilation pipe 18 collects and processes the dust brought out from the box 1 through the recovery box 20. The conveying pipe 21 is used to convey the hot air into the cooling water tank 26. The interior of the conveying pipe 21 is fixedly connected with a mounting plate 22. The hot air enters the next section of the conveying pipe 21 through the through hole 23. The impurities in the hot air are filtered through the dust removal net 25 arranged inside the mounting plate 22. The slot 24 is used to install the dust removal net 25.

[0028] Reference Figure 1 and 4 The bottom end of the delivery pipe 21 is fixedly connected to a water tank 26, the front side of the box body 1 is rotatably connected to a box door 2, an observation window 3 is provided inside the box door 2, the four corners of the bottom of the box body 1 are fixedly connected to support legs 4, and the right side of the box body 1 is fixedly connected to a controller 5.

[0029] The hot air inside the box body 1 is cooled by the water in the water tank 26 . The box door 2 is used to close and open the box body 1 . The support legs 4 are used to support the box body 1 during operation. The controller 5 is used to control the fan 7 , the valve 19 , and the heater 10 .

[0030] Working principle: When using the device, the staff opens the door 2 and removes the two sides of the placement plate 14 from the insertion rod 15, then places the object to be dried on the surface of the placement plate 14, and then puts the placement plate 14 into the interior of the box 1 and inserts the corresponding jack 16 into the insertion rod 15 on the support plate 13 and closes the door 2, and finally turns on the fan 7 and the heater 10 through the controller 5. The fan 7 blows the hot air generated by the heater 10 into the outlet pipe 11 and blows it evenly to the object to be dried on the surface of the placement plate 14 through the outlet 12. Since the controller 5 can arbitrarily adjust the wind speed of the fan 7 and the heating temperature of the heater 10, the drying efficiency is improved. After drying, the hot air inside the box 1 is discharged through the ventilation pipe 18. The ventilation pipe 18 collects and processes the dust brought out of the box 1 through the recovery box 20, and the hot air enters the water tank 26 through the conveying pipe 21 for cooling. Before entering the water tank 26, the hot air is filtered through the dust removal net 25 for impurities, and quickly cooled, thereby improving the working efficiency of the oven.
