[0018] 1. The threaded structure on the outside of the knob of the present invention allows the user to rotate it, and the outer knob is rotated to make the ventilation cover plate and the compress box movable. The inner knob moves in the stable groove, thereby causing the rotation of the rotating rod. The rotation of the rotating rod drives the rotation of the adjusting block. Since the adjusting block cooperates with the rotating rod thread, the rotation of the rotating rod causes the adjusting block to move along the axial direction of the rotating rod. The limit block is at the far end of the rotating rod. During the movement, the limit block cooperates with the limit plate to limit the movement range of the adjusting block, thereby ensuring the stability of the anti-dismantling mechanism. The anti-dismantling plates in the rotating grooves on both sides of the knob can prevent illegal disassembly through the movement of rotating the inner knob.

[0019] 2. The output end of the servo motor of the present invention drives the adjusting rack through a threaded rod. The servo motor rotates the threaded rod according to the control signal, adjusts the position of the adjusting rack on the guide rod, and the rack structure of the adjusting rack meshes with the incomplete gear. The movement of the adjusting rack causes the incomplete gear to rotate. The rotation of the incomplete gear drives the movable rod connected to it to move. The movement of the movable rod changes the wind direction through the spoiler, improves the hot compress effect by affecting the dissipation or retention of heat, can help to evenly distribute heat, and enhance the temperature stability of the hot compress area.

[0020] 3. The present invention designs an isolation plate between the wind direction frame and the adjustment frame, thereby effectively isolating the mechanical interference between the wind direction frame and the adjustment frame, ensuring that the wind direction frame and the adjustment frame are not affected by other components during the adjustment process, which helps to improve the stability and accuracy of the system, and can prevent the drug from spilling, ensuring that the drug is not affected during the adjustment process.

[0021] 4. The driving rod of the present invention is connected to the driving wheel, and the driving wheel is meshed with the adjusting rack. When the adjusting rack rotates, the driving wheel also moves accordingly, thereby driving the driving rod to rotate. A swinging piece is fixedly connected to one side of the driving rod. When the driving rod and the driving wheel are driven and moved by the adjusting rack, the swinging piece will follow the movement, thereby affecting the working position of the heater. Several swinging pieces are fixed in the fixed frame and connected through a transmission plate. The transmission plate transmits movement between the swinging pieces, thereby adjusting the position of the heater. The limit pieces are fixed on both sides of the fixed frame and are located on one side of the transmission plate. During the horizontal movement of the transmission plate, the limit pieces are used to limit the movement range of the transmission plate to ensure that it moves within the set range and avoids exceeding the predetermined position. The heater is connected to the internal single-chip microcomputer and the power supply through a cable. The single-chip microcomputer controls the heating function of the heater and adjusts the working state of the heater as needed to achieve precise heating control. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

The medicine compress box 1 is installed with a wind direction adjustment mechanism 8 in the mounting groove 7, and a heating adjustment mechanism 9 is provided on one side of the wind direction adjustment mechanism 8.

[0034] In this embodiment, specifically, the anti-disassembly mechanism 5 includes a knob 501, an inner knob 502, a stable groove 503, a limit plate 504, an adjustment block 505, a connector 506, a transmission rod 507, a limit block 508, an anti-disassembly plate 509, a rotation groove 510 and a rotation rod 511. The four corners of the disassembly ventilation cover 4 are movably connected with knobs 501, the surface of the knob 501 is a threaded structure, and a stable groove 503 is opened inside the knob 501. The stable groove 503 is movably connected with an inner rotary The inner knob 502 is movably connected to the limit plate 504 on the limit plate 504, and the surface of the rotate rod 511 is a threaded structure. The side of the rotate rod 511 away from the inner knob 502 is fixedly connected to the limit block 508. The limit block 508 and the limit plate 504 are movably connected to the adjusting block 505 on the transmission rod 507.
