[0029] The patient sits on the cushion 4 of the instrument body 1, and the cushion 4 improves the comfort. The power switch is turned on, and the electromagnetic structure 6 is controlled by the display controller 3 to treat the patient. The servo motor 9 drives the rotating shaft 10 to rotate, so that the fan 8 rotates. When the rotating shaft 10 rotates, it drives the worm gear 20 to rotate, so that the worm 21 drives the rotating column 22 to rotate. Through the magnetic effect of the first magnetic block 19 and the second magnetic block 24, the movable block 23 drives the movable rod 18 to move when it moves. When the rotating column 22 rotates, the movable block 23 moves along the movable groove on the outer surface of the rotating column 22, so that the movable rod 18 drives the electric push rod 17, the fixed plate 16 and the connecting rod 15 to move up and down, so that the sealing plate 14 moves up and down inside the air outlet, so that the size of the air outlet can be adjusted, so that the instrument body 1 dissipates heat through the air outlet and the heat dissipation port 5. When the temperature inside the instrument body 1 rises, when the movable block 23 moves to the top of the movable groove on the outer surface of the rotating column 22, the moving rod 18 drives the electric push rod 17, the fixed plate 16, the connecting rod 15 and the sealing plate 14 to move upward, so that the sealing plate 14 moves to the movable groove at the top of the air outlet. At the same time, the electric push rod 17 drives the moving rod 18 and the first magnetic block 19 to move toward the fixed plate 16, so that the first magnetic block 19 is separated from the second magnetic block 24, so that the positions of the fixed plate 16, the connecting rod 15 and the sealing plate 14 are fixed, so that the air outlet is fully exposed, and the instrument body 1 is cooled by the rotation of the fan 8. Therefore, by controlling the size of the air outlet of the mounting block 7, the heat dissipation and air outlet effect of the heat dissipation port 5 can be adjusted according to the temperature, so as to improve the heat dissipation effect inside the instrument body 1.

[0030] like Figures 4 to 7 As shown, the first baffle 12 is located at the top of the heat dissipation port 5, the three air outlets are arranged corresponding to the heat dissipation port 5, the movable port is arranged corresponding to the connecting rod 15, the connecting rod 15 and the fixing plate 16 are located at the end of the mounting block 7 away from the fan 8, slots are provided on both sides of the sealing plate 14, and sockets are provided on both sides of the mounting block 7 and above the three air outlets. The tops of both sides of the mounting block 7 are fixedly connected with support frames 25, and the shape of the support frame 25 is L-shaped.

[0031] The heat dissipation port 5 on one side of the mounting block 7 is shielded by the first baffle 12, the second baffle 13, and the mounting block 7, thereby reducing dust from entering the interior of the instrument body 1 through the heat dissipation port 5 when not in use, thereby affecting the use of the instrument body 1. When the instrument body 1 is used for treatment, the temperature is too high. After the air outlet is fully opened, the connecting rod 15 drives the sealing plate 14 to move completely into the interior of the moving groove through the moving port. The jacks on both sides of the mounting block 7 are arranged corresponding to the slots on both sides of the sealing plate 14. The electric telescopic rod 26 installed at the bottom of the support frame 25 pushes the connecting plate 27 to move toward the mounting block 7, so that the plug rod 28 moves into the interior of the slot through the jack. The plug rod 28 is connected to the slot, so that the sealing plate 14 is fixed inside the moving groove, thereby improving the stability of the sealing plate 14 and further improving the heat dissipation effect inside the instrument body 1.

[0032] like Figures 4 to 7 As shown, the bottom of the support block 11 is fixedly installed on the bottom inner wall of the instrument body 1, a temperature sensor is fixedly installed on the side of the support block 11 close to the electric push rod 17, the top of the worm 21 is rotatably connected to the first connecting frame 29, the bottom of the first connecting frame 29 is fixedly installed on the top of the support block 11, the bottom of the rotating column 22 is rotatably connected to the first support plate 30, one side of the first support plate 30 is fixedly installed on the support block 11, and the moving rod 18 is located on the top of the first support plate 30.

[0033] The temperature sensor is used to monitor the temperature inside the instrument body 1, so that the sealing plate 14 can control the size of the air outlet, thereby improving the heat dissipation effect inside the instrument body 1. The servo motor 9 is installed through the support block 11, so that the servo motor 9 can rotate with the rotating shaft 10 to rotate the fan 8, and the first connecting frame 29 is fixed by the support block 11, and the rotating column 22 is installed on the first support plate 30, so that the rotating shaft 10 drives the worm gear 20, the worm 21, and the rotating column 22 to rotate stably, so that under the action of the movable block 23, the first magnetic block 19, the second magnetic block 24, the moving rod 18 and the electric push rod 17, the fixed plate 16 drives the connecting rod 15 and the sealing plate 14 to move, thereby facilitating the heat dissipation of the instrument body 1.

[0035] When the rotating column 22 rotates, the movable block 23 moves along the movable groove, and the first magnetic block 19 and the second magnetic block 24 drive the movable rod 18 and the electric push rod 17 to move up and down, so that the fixed plate 16 drives the connecting rod 15 and the sealing plate 14 to move in the air outlet. When the electric push rod 17 drives the fixed plate 16 to move, the fixed plate 16 drives the fixed block 31 to move, so that the connecting spring 32 stretches and contracts. When the movable block 23 moves to the top of the movable groove, the movable block is driven to move by the electric push rod 17, and the first magnetic block 19 and the second magnetic block 24 are separated. Therefore, the sealing plate 14 moves to the inside of the movable groove, and the connecting rod 15 and the fixed plate 16 move upward. The fixed block 31 supports and fixes the electric push rod 17 through the action of the connecting spring 32, which is convenient for supporting and fixing the position of the electric push rod 17, so that the position of the sealing plate 14 is fixed, and the stability of the sealing plate 14 in the movable groove is further improved, so that the air outlet is completely exposed, so that the heat dissipation port 5 dissipates heat to the instrument body 1, and the use effect of the instrument body 1 is improved.

[0036] like Figures 9 and 10 As shown, a first gear 33 is fixedly installed at one end of the rotating shaft 10, a second gear 34 is meshed with one side of the first gear 33, a rotating rod 35 is fixedly connected to the middle of the second gear 34, a rack 36 is meshed with one side of the second gear 34, a fixed rod 37 is fixedly connected to one side of the bottom end of the rack 36, a second support plate 38 is fixedly connected to one end of the fixed rod 37, a second connecting frame 39 is rotatably connected to one end of the rotating rod 35, the bottom of the second connecting frame 39 is fixedly installed with the top of the support block 11, the second support frame 25 is located on one side of the servo motor 9, the second connecting frame 39 is L-shaped, the horizontal end of the second connecting frame 39 is located at the top of the rack 36, and a first electromagnet 40 is fixedly installed at its bottom, the first gear 33 is located on one side of the worm gear 20, the second gear 34 is located at the top of the rack 36, and a second electromagnet 41 is provided on the top of the rack 36.

[0037] When the rotating shaft 10 rotates, the first gear 33 is driven to rotate, and the first gear 33 drives the second gear 34 to rotate, so that the rack 36 drives the fixed rod 37 and the second support plate 38 to move upward. When the rack 36 moves upward to the bottom of the second connecting frame 39, the second electromagnet 41 at the bottom of the rack 36 is attracted by the first electromagnet 40 at the bottom of the second connecting frame 39, and the fixed rod 37 drives the second support plate 38 to move to the top of the instrument body 1, so that when the patient sits on the instrument body 1 for treatment, the second support plate 38 supports the patient's back, so as to improve the treatment effect of the patient. When the patient's treatment is completed, the servo motor 9 drives the rotating shaft 10 and the first gear 33 to reverse, so that the second gear 34 rotates in the opposite direction to the first gear 33, and the first electromagnet 40 and the second electromagnet 41 repel each other, pushing the rack 36 to move downward, so that the rack 36 is better engaged with the second gear 34, so that the rack 36 drives the fixed rod 37 and the second support plate 38 to move downward, so that the second support plate 38 moves to the inside of the instrument body 1 for protection.

[0038] like Figure 1 , Fig.10 As shown, an arc groove is provided on the top of one end of the instrument body 1 close to the display controller 3, the top of the second support plate 38 is located inside the arc groove, and two mounting grooves are provided on the side of the second support plate 38 away from the fixed rod 37, and telescopic plates 42 are provided inside the two mounting grooves.

The two fixed grooves 43 are arranged corresponding to the two mounting grooves, and the bottom end of the telescopic plate 42 is plugged into the two fixed grooves 43.

[0039] The second support plate 38 moves to the top of the instrument body 1 through the arc groove to support the patient's back. When the second support plate 38 moves to the outside of the top of the instrument body 1, the telescopic plate 42 is rotated to move the telescopic plate 42 out of the mounting groove, so that the bottom end of the telescopic plate 42 moves to the top of the fixed groove 43 at the top of the mounting plate 2, and then the telescopic plate 42 is pulled so that the bottom of the telescopic plate 42 is inserted into the inside of the fixed groove 43, so that the telescopic plate 42 supports and fixes the second support plate 38, which is convenient for improving the stability of the second support plate 38 and the service life of the second support plate 38, thereby improving the comfort of patient treatment.

[0040] Working principle: When in use, the patient sits on the instrument body 1, turns on the power switch, controls the electromagnetic structure 6 through the display controller 3 to treat the patient, and drives the rotating shaft 10 to rotate through the servo motor 9, so that the fan 8 rotates, and when the rotating rod 35 rotates, it drives the worm gear 20 to rotate, so that the worm 21 drives the rotating column 22 to rotate, and through the magnetic effect of the first magnetic block 19 and the second magnetic block 24, the movable block 23 moves and drives the movable rod 18 to move. When the rotating column 22 rotates, the movable block 23 moves along the movable groove on the outer surface of the rotating column 22, so that the movable rod 18 drives the electric push rod 17, the fixed plate 16 and the connecting rod 15 to move up and down, so that the sealing plate 14 moves up and down inside the air outlet, so that the size of the air outlet is adjusted. When the temperature sensor detects that the temperature inside the instrument body 1 rises, the movable block 23 moves to the top of the movable groove on the outer surface of the rotating column 22, and the movable rod 18 drives the electric push rod 17, the fixed plate 16 and the connecting rod 15 to move up and down, so that the sealing plate 14 moves up and down inside the air outlet, so that the size of the air outlet is adjusted. When the temperature sensor detects that the temperature inside the instrument body 1 rises, the movable block 23 moves to the top of the movable groove on the outer surface of the rotating column 22, and the movable rod 18 drives the electric push rod 17, the fixed plate 16, the connecting rod 15 and the sealing plate 14 move upward, so that the sealing plate 14 moves to the inside of the moving groove at the top of the air outlet, and at the same time, the moving rod 18 and the first magnetic block 19 are driven by the electric push rod 17 to move toward the fixed plate 16, so that the first magnetic block 19 is separated from the second magnetic block 24, so that the positions of the fixed plate 16, the connecting rod 15 and the sealing plate 14 are fixed. When the fixed plate 16 moves upward, the fixed block 31 is driven to move, so that the connecting spring 32 is stretched. Through the action of the connecting spring 32 and the fixed block 31, the positions of the electric push rod 17, the moving rod 18 and the first magnetic block 19 are fixed, and at the same time, the electric telescopic rod 26 is started again to push the connecting plate 27 and the plug rod 28 to move, so that the plug rod 28 passes through the jack and is plugged into the slots on both sides of the sealing plate 14, and the sealing plate 14 is fixed in the moving groove, so that the air outlet is completely exposed, and the heat is dissipated to the instrument body 1 through the rotation of the fan 8 to improve the heat dissipation effect inside the instrument body 1.

[0041] When the servo motor 9 rotates and drives the rotating shaft 10 to rotate, the first gear 33 drives the second gear 34 and the rotating rod 35 to rotate, so that the rack 36 drives the fixed rod 37 and the second support plate 38 to move upward, and the second support plate 38 moves to the top of the instrument body 1 through the arc groove. When the rack 36 moves to the bottom of the second connecting frame 39, the rack 36, the fixed rod 37 and the second support plate 38 are limited by the action of the first electromagnet 40 and the second electromagnet 41, and then the telescopic plate 42 inside the mounting groove on one side of the second support plate 38 is rotated so that the telescopic plate 42 moves out of the mounting groove, so that the bottom end of the telescopic plate 42 moves to the top of the fixed groove 43 at the top of the mounting plate 2, and then the telescopic plate 42 is pulled so that the bottom of the telescopic plate 42 is inserted into the inside of the fixed groove 43, so that the telescopic plate 42 supports and fixes the second support plate 38, which is convenient for supporting the patient's back, improving the patient's comfort during treatment, and improving the treatment effect.
