A rotating cylinder is fixed to the left side of the movable frame. The outer sidewall of the rotating cylinder is rotatably connected to a cylindrical tube, and the left side of the cylindrical tube is fixedly connected to the right side of the housing.

[0009] Preferably, two fixing holes are provided on the outer sidewall of the rotating cylinder. A rectangular plate is fixed inside the fixing hole.

[0011] The utility model provides an anti-overdrying automatic interlocking structure. Compared with the prior art, the following beneficial effects are achieved:

[0012] 1. For this anti-overdrying automatic interlocking structure, by setting a power-off switch, connect the power cord to the power socket, insert the power cord of the drying device into the socket of the device, start the device through the button, and then set the drying time through the button. When the drying time arrives, the processing module activates the electromagnet. The electromagnet attracts the iron sheet, and the iron sheet drives the movable frame to move, so that the two electrical sheets are separated, and thus the power is cut off, and the drying device stops working to prevent over-drying. When the movable frame moves, the damper will play a buffering role to slow down the contact between the electromagnet and the iron sheet and the contact collision between the two electrical sheets, preventing collision damage.

For this anti-overdrying automatic interlocking structure, by setting a connecting mechanism, the magnetic plate is attracted to the outside of the drying device, so that the device is connected to the drying device. Then press the round rod, and the round rod moves. In this way, the first spring pushes the top block into the inside of the annular groove. The top block drives the moving rod and the tooth block to move, and the tooth block moves out of the tooth groove, so that the housing can rotate to adjust the angle of the housing for convenient use. After the adjustment is completed, release the round rod, and the second spring pushes the round rod to move. The round rod pushes the top block, and the tooth block is inserted into the tooth groove again to limit the rotation of the cylindrical tube and the housing and fix the angle of the housing.

Specific embodiments

[0020] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0021] Please refer to Figures 1-5, the present utility model provides a technical solution: an anti-overdrying automatic interlock structure, including a housing 2. Inside the housing 2, there is a circuit board 11. On the front surface of the circuit board 11, a display screen 5 is fixed. Below the display screen 5 on the front surface of the circuit board 11, there are multiple buttons 3. The front ends of the buttons 3 and the front end of the display screen 5 both pass through the housing 2. On the rear surface of the circuit board 11, a processing module 8 is fixed. On the rear surface of the circuit board 11, to the right of the processing module 8, a time module 7 is fixed. On the rear surface of the circuit board 11, to the left of the processing module 8, a socket 10 is fixed. On the rear surface of the circuit board 11, below the socket 10, a power cord 1 is fixed. The left end of the power cord 1 and the left side of the socket 10 both pass through the housing 2. On the rear surface of the circuit board 11, a power-off switch 9 is fixed. The power-off switch 9 includes a fixed frame 20. The rear surface of the fixed frame 20 is fixedly connected to the front surface of the circuit board 11. Inside the fixed frame 20, two fixing plates 15 are fixed. On the opposite sides of the two fixing plates 15, dampers 19 are fixed. Inside the fixed frame 20, a moving frame 17 is slidably connected. The end of the damper 19 away from the fixing plate 15 is fixedly connected to the moving frame 17. To the right of the left fixing plate 15 and below the damper 19, a tension spring 16 is fixed. The other end of the tension spring 16 is fixedly connected to the moving frame 17. On the left side of the moving frame 17 and the right side of the left fixing plate 15, electrical sheets 18 are fixed. On the right side of the moving frame 17, an iron sheet 14 is fixed. On the left side of the right fixing plate 15, an electromagnet 13 is fixed. Connect the power cord 1 to a power socket, insert the power cord of the drying device into the device socket 10 inside. Start the device through the button 3, and then set the drying time through the button 3. When the drying time arrives, the processing module 8 starts the electromagnet 13. The electromagnet 13 attracts the iron sheet 14, and the iron sheet 14 drives the moving frame 17 to move. In this way, the two electrical sheets 18 are separated, and thus the power is cut off, and the drying device stops working, preventing over-drying. Moreover, when the moving frame 17 moves, the damper 19 will play a buffering role, slowing down the contact between the electromagnet 13 and the iron sheet 14 and the contact collision between the two electrical sheets 18, preventing collision damage.

[0022] Further, a connecting mechanism 4 is provided above the housing 2. The connecting mechanism 4 includes a movable frame 21. A magnetic plate 6 is fixed inside the movable frame 21. A rotating cylinder 32 is fixed on the left side of the movable frame 21. The outer sidewall of the rotating cylinder 32 is rotatably connected to a cylindrical tube 12. The left side of the cylindrical tube 12 is fixedly connected to the right side of the housing 2. Two fixing holes 23 are formed in the outer sidewall of the rotating cylinder 32. A rectangular plate 26 is fixed inside the fixing hole 23. A moving rod 27 is slidably connected inside the rectangular plate 26. Tooth blocks 22 and top blocks 25 are respectively fixed at both ends of the moving rod 27. A first spring 28 is sleeved on the outer side of the moving rod 27 between the top block 25 and the rectangular plate 26. A tooth groove 31 is formed in the inner sidewall of the cylindrical tube 12. A second spring 24 is fixed inside the rotating cylinder 32. The other end of the second spring 24 is fixed to a round rod 29. A ring groove 30 is formed in the outer sidewall of the round rod 29. The elastic force of the second spring 24 is greater than the sum of the elastic forces of the two first springs 28. The right end of the round rod 29 passes through the movable frame 21 and attracts the outside of the magnetic plate 6 and the drying device, so that the device is connected to the drying device. Then, the round rod 29 is pressed. The round rod 29 moves. In this way, the first spring 28 pushes the top block 25 into the inside of the ring groove 30. The top block 25 drives the moving rod 27 and the tooth block 22 to move. The tooth block 22 moves out of the tooth groove 31. In this way, the housing 2 can rotate to adjust the angle of the housing 2 for convenient use. After the adjustment is completed, the round rod 29 is released. The second spring 24 pushes the round rod 29 to move. The round rod 29 pushes the top block 25. The tooth block 22 is inserted into the tooth groove 31 again to limit the rotation of the cylindrical tube 12 and the housing 2 and fix the angle of the housing 2.

[0023] During operation, connect the power cord 1 to the power socket, insert the power cord of the drying device into the device socket 10, start the device through the 3 keys, and then set the drying time through the key 3. When the drying time arrives, the processing module 8 activates the electromagnet 13. The electromagnet 13 attracts the iron sheet 14. The iron sheet 14 drives the moving frame 17 to move. In this way, the two electrical sheets 18 are separated, and thus the power is cut off and the drying device stops working to prevent over-drying. When the moving frame 17 moves, the damper 19 will play a buffering role to slow down the contact between the electromagnet 13 and the iron sheet 14 and the contact collision between the two electrical sheets 18 to prevent collision damage.
