[0030] Step 4: The infrared sensor unit detects whether there is a learner on the seat. Once the learner leaves the seat, the learning tablet will pause playing to prevent the learner from missing any content.

[0031] Step 5: The mosquito repellent module is used to ensure that the environment where the learners are located is free from mosquitoes;

[0032] Step 6: The environment adjustment module can ensure that once the learning environment is not good, the environment adjustment module will automatically start to adjust the learning environment and create a good environment for learners.

[0035] The display tube provided allows learners to directly observe the internal water usage so as to add water in time. The connecting tube provided is a flexible hose which can be bent to ensure that the lifting frame can move up and down.

[0036] When the environment is good, the first hydraulic rod drives the slider to move. At this time, the lifting frame is located inside the first installation frame for storage, and will not affect the external environment.

[0037] In the mosquito repellent state, the insect repellent stick or other insect repellent materials are placed inside the sealing frame, and the second fan slowly rotates to drive the air flow, the air passes through the inside of the raised cylinder, and then is discharged through the mesh.

[0066] Traditional online learning platforms usually adopt a linear structure, arranging courses in a certain order. Learners need to study according to a preset process while sitting in a chair. However, during the learning process, learners are affected by various environments. In a dry environment in winter, they are prone to dry and painful throats if they stay in this environment for a long time. In a humid environment in summer, they are sticky and wet, which is uncomfortable and not conducive to learners to concentrate on learning. When in use, the humidity sensor 8 can detect the learning environment. Once the environment is too dry or too humid, the atomizer 604 or the first fan 609 inside the first installation frame 601 is started. At this time, the dry environment is humidified through the hollow plate 607 and the air pipe 608, or the humid environment can be dried by starting the first fan 609 and the heating network 610, so as to create a good environment for learners.

[0067] The learning tablet 10 can provide interaction and communication functions between learners. Learners can discuss and communicate with other learners on the platform and share their learning experience.

[0068] The infrared sensor unit 11 uses external sensors to collect external data, and achieves a stable intelligent system through infrared sensing distance measurement, temperature sensing measurement, thermal imaging system, etc.; it has active performance, high data transmission rate, and presents the above data on the smart desktop. When the user starts to use it, the study table will detect whether the sitting posture is correct through various sensors. If it is not correct, it will remind through the alarm 13 to achieve the correct sitting posture;

[0069] In this embodiment, the light intensity sensor 18 can monitor the light intensity of the surrounding environment and control the lighting fixture 19 through PWM dimming. PWM dimming can control the time ratio of current conduction and shutdown by keeping the forward current of the LED constant, that is, changing the duty cycle of the input pulse signal to make the LED produce light and dark changes, thereby achieving the purpose of adjusting the light intensity. When the frequency of LED light and dark changes is greater than 120Hz, the human eye will not feel flickering, and the brightness will feel relatively constant without much change. The advantage of PWM dimming is that the forward current of the LED is constant, which determines that its chromaticity will not change like analog dimming. Good eyesight is the guarantee of learning.

[0070] Some mosquito repellents, mosquito repellent sticks and other objects are located between the partitions 706, and the mosquito repellent gas generated is discharged through the air holes 705 for the purpose of repelling mosquitoes and insects;

[0071] In dry weather, the water droplets atomized by the atomizer 604 enter the air pipe 608 through the hollow plate 607 and are then discharged to humidify the surrounding environment. In humid weather, the heating network 610 is started, and the first fan 609 is started to ensure that dry air is discharged. An air inlet is provided on one side to ensure air circulation, so as to dry the surrounding environment and provide a comfortable environment for users.

[0074] When the environment is good, the first hydraulic rod 612 drives the slider 613 to move. At this time, the lifting frame 603 is located inside the first installation frame 601 for storage, and will not affect the external environment.

[0075] In this embodiment, the inclined first hydraulic rod 612 can reduce the occupied space. At the same time, when the first hydraulic rod 612 is started, it drives the slider 613 to slide, so as to facilitate the up and down movement of the lifting frame 603.

[0076] Example 3

[0077] This embodiment is an improvement on embodiment 1. Figure 2 Specifically, the display tube 606 is made of a transparent glass plate.

[0078] The display tube 606 is provided to facilitate learners to directly observe the internal water usage so as to add water in time. The connecting tube 605 is a flexible tube that can be bent to ensure that the lifting frame 603 can move up and down.

[0081] Second hydraulic rods 708 are installed on both sides of the second installation frame 701 , and the free ends of the second hydraulic rods 708 are fixedly connected to the moving platform 703 .

[0082] In the mosquito repellent state, the insect repellent stick or other insect repellent materials are placed inside the sealing frame 704, and the second fan 702 rotates slowly to drive the air flow, and the air passes through the inside of the protruding cylinder 707 and then is discharged through the mesh 709. At this time, the air can carry the insect repellent gas and be discharged through the air vent 705 for the purpose of mosquito repellent;

[0083] In this embodiment, the second hydraulic rod 708 is started to drive the movable platform 703 to move, and the movable platform 703 can be raised and lowered. When not in use, the movable platform 703 drives the sealing frame 704 to move downward, and cooperates with the second installation frame 701 to achieve sealing and prevent gas discharge.
