[0024] A cleaning mechanism 2 is provided below the training platform 1; the cleaning mechanism 2 comprises a connection box 201, the outer surface of the connection box 201 is fixedly connected to the inner wall of the training platform 1, an earphone body 202 is provided inside the connection box 201, a touch panel 3 and a display 4 are fixedly installed on the inner bottom wall of the training platform 1, and the display 4 is electrically connected to the touch panel 3 and the earphone body 202 through wires. The user listens to the English listening content through the earphone body 202, and then answers the test questions displayed on the display 4 through the touch panel 3, thereby achieving the purpose of English listening training.

[0025] Two groups of connecting springs 203 and pressure sensors 205 are fixedly installed on the inner bottom wall of the connecting box 201, and a connecting plate 204 is fixedly installed on the top of the two groups of connecting springs 203. The detection end of the pressure sensor 205 is in contact with the bottom surface of the connecting plate 204. The model of the pressure sensor 205 is MS54XX. Two groups of cylinders 7 are fixedly installed on the upper surface of the base 5. The telescopic end of each cylinder 7 is fixedly connected to the bottom surface of the training platform 1. The power provided by the cylinder 7 is used to drive the training platform 1 to move up and down, thereby adjusting the height of the training platform 1, thereby making the device suitable for students of different heights and increasing the scope of use of the device.

[0026] An earphone holder 206 and a connecting column 207 are fixedly installed on the upper surface of the connecting plate 204, and the outer surface of the earphone holder 206 contacts the inner wall of the earphone body 202. A sealing cover 8 is movably hinged on the inner bottom wall of the training platform 1, and a pull rod 9 is fixedly installed on the upper surface of the sealing cover 8. The bottom surface of the sealing cover 8 contacts the upper surface of the connecting box 201. The installation of the sealing cover 8 and the pull rod 9 serves to seal the connecting box 201, thereby avoiding dust from entering the interior of the connecting box 201 when the earphone body 202 is stored, thereby ensuring the cleanliness of the earphone body 202.

[0027] Hydraulic rods 208 are fixedly installed on both sides of the connecting column 207, and a rotating motor 209 is fixedly installed on the telescopic end of each hydraulic rod 208, and a brush roller 210 is fixedly installed on the output end of the power of each rotating motor 209. A lamp holder 10 is fixedly installed on the inner wall of the connecting box 201, and an ultraviolet lamp 11 is fixedly installed on the inner wall of the lamp holder 10. The installation of the lamp holder 10 and the ultraviolet lamp 11 plays a role in sterilizing the earphone main body 202, thereby minimizing the spread of germs between users through the earphone main body 202.

[0028] A fan 211 and a controller 212 are fixedly installed on the front of the connecting box 201, and the output end of the fan 211 power passes through the connecting box 201 and extends to the interior of the connecting box 201. The left side of the connecting box 201 is fixedly connected with an air outlet pipe 213 and the outer surface of the air outlet pipe 213 is fixedly installed with a solenoid valve 214. Two groups of telescopic rods 12 are fixedly installed on the inner bottom wall of the connecting box 201, and the telescopic end of each telescopic rod 12 is fixedly connected to the bottom surface of the connecting plate 204.

[0029] The working principle of the utility model is as follows: when in use, the user takes out the earphone body 202 from the inside of the connection box 201, and then the user wears the earphone body 202 on the ear to listen to the content of English listening, and then the user answers the test questions on the display 4 on the touch tablet 3, thereby achieving the purpose of the user's English listening training. When the user's training is completed, the user hangs the earphone body 202 on the earphone rack 206 and closes the sealing cover 8. Under the action of the gravity of the earphone body 202, the connecting plate 204 is driven to move downward, so that the pressure generated by the connecting plate 204 on the pressure sensor 205 increases. When the pressure sensor 205 detects the pressure increase, the pressure sensor 205 transmits a signal to the controller 212, so that the control The device 212 controls the hydraulic rod 208, the rotating motor 209, the fan 211, the solenoid valve 214 and the ultraviolet lamp 11 to work, and utilizes the power provided by the rotating motor 209 to drive the brush roller 210 to rotate. At the same time, the power provided by the hydraulic rod 208 is used to drive the brush roller 210 to extend into the interior of the earphone body 202, and then the fan 211 is used to provide wind force to blow on the earphone body 202, thereby achieving the purpose of cleaning the earphone body 202 and ensuring the cleanliness of the earphone body 202. At the same time, the ultraviolet lamp 11 is used to sterilize and disinfect the outer surface of the earphone body 202, so as to avoid the spread of germs between users through the earphone body 202 as much as possible, and reduce the impact of the earphone body 202 being dirty or having a strong odor on the user's hearing training.
