[0024] As shown in Figure 4 , a scratchproof roller 2 is arranged at the upper end inside the shell 1, and the two ends of the scratchproof roller 2 are rotatably connected with the front and rear ends inside the shell 1, respectively, when the external damp toilet paper is transmitted to the inside of the shell 1, the rotating scratchproof roller 2 can avoid damage of the toilet paper to the shell 1 itself due to friction;

[0025] The lower end of the scratchproof roller 2 is obliquely provided with a heating sheet 4, the heating sheet 4 is made of stainless steel, the damp toilet paper is contacted by the stainless steel to avoid rusting of the inside of the shell 1 due to dampness, and a first heating block 5 is arranged on the side of the inside of the shell 1 close to the heating sheet 4, when the damp toilet paper is conveyed to the inside of the shell 1, the heating sheet 4 and the adhered toilet paper can be heated by starting of the first heating block 5, the heating can play a preheating role, and wrinkles can be avoided due to sudden contact of the damp toilet paper with the second heating block 7 for heating;

[0026] In addition, the lower end of the other side of the heating sheet 4 is provided with an extrusion roller 15, one end of the extrusion roller 15 is rotated by the output of a motor, the rotation of the extrusion roller 15 can be driven by the output of the extrusion roller 15, the rotation of the extrusion roller 15 can extrude the transmitted toilet paper, so that the liquid in the toilet paper can be discharged, the time of subsequent drying is reduced, and the drying efficiency is improved, as shown in Figure 5As shown, the lower end of the shell 1 is obliquely provided with a liquid flow guide 11, and the liquid discharged through the extrusion between the extrusion roller 15 and the shell 1 will fall on the upper end of the liquid flow guide 11. The liquid flow guide 11 will guide the liquid, and the liquid flow guide 11 and the shell 1 are provided with a water storage cavity 14. The liquid after being guided will be transmitted and stored in the water storage cavity 14.

[0027] In order to efficiently dry the toilet paper, as shown in Figure 3 and Figure 4 As shown, the lower end of the extrusion roller 15 is obliquely provided with a fixed frame 6, and the inside of the two fixed frames 6 is provided with a second heating block 7. The second heating blocks 7 inside the two fixed frames 6 are mirror arranged, and the toilet paper transmitted between them is dried at the same time. At the same time, two rows of wire rods 8 are longitudinally arranged between the two second heating blocks 7. The two rows of wire rods 8 can guide the toilet paper during transmission, so that the toilet paper is transmitted between the two wire rods 8 and continuously contacts the heating of the second heating block 7 to dry;

[0028] The lower end of the inside of the shell 1 is provided with a dehumidifier 9, which can dehumidify the gas inside the shell 1, so as to avoid the inside of the shell 1 being continuously humid for a long time. The liquid produced by the dehumidifier 9 is transmitted to the water storage cavity 14;

[0029] As shown in Figure 2 , Figure 4 and Figure 5 The end of the first transmission pipe 10 not connected with the air heater 3 extends to the other side of the extrusion roller 15, and the end of the second transmission pipe 13 not connected with the air heater 3 extends to the lower end of the side of the dehumidifier 9.

[0030] Working principle: When using the device and drying the wet toilet paper, the wet toilet paper adheres to the anti-scratch roller 2 and enters the inside of the shell 1. The wet toilet paper actively enters the inside of the shell 1 due to its own weight, and adheres to the inclined heating plate 4 when entering the inside of the shell 1. The first heating block 5 inside the shell 1 can heat the heating plate 4, so that the heating plate 4 transfers heat to the adhered toilet paper in advance, so that the toilet paper can be preheated. After preheating, the wet toilet paper will be squeezed between the squeezing roller 15 and the shell 1, and the squeezing will actively discharge the liquid inside the toilet paper, so that the liquid can be actively discharged and transferred to the water storage chamber 14 after being guided by the liquid guide plate 11. After being squeezed by the squeezing roller 15, the toilet paper will be transferred between the two rows of wire rods 8 until the toilet paper is preheated. The raw paper is discharged from the outside of the shell 1, and when the toilet paper is transmitted between the two rows of conductors 8, the second heating block 7 inside the fixed frame 6 continuously heats and dries the transmitted toilet paper. During the transmission, the start-up of the hot air blower 3 can extract the gas inside the shell 1. The gas will flow into the inside of the shell 1 from the first transmission pipe 10 and directly contact the toilet paper. The gas will pass through the toilet paper and be sucked in from the expansion frame 12, and will be transmitted by the second transmission pipe 13 and transported to the hot air blower 3 to realize circulation. During the circulation process, the dehumidifier 9 will remove the moisture generated in the gas during the circulation process, remove the moisture in the air, and keep the inside of the shell 1 dry. While keeping it dry, the liquid generated by the dehumidifier 9 will also be synchronously transmitted to the water storage chamber 14.
