The first connecting rod 35 is slidably connected inside the second rotating disk 36, and the first rotating disk 34 is fixedly connected to the surface of the first connecting rod 35.

[0025] A second drive motor 611 is fixedly connected to the top of the support base 5. A cylindrical gear 612 is fixedly connected inside the second drive motor 611 through an output shaft. The cylindrical gear 612 meshes with a rotating ring 610, and the rotating ring 610 is rotatably connected inside the support base 5.

[0026] The mounting frame 69 is internally fixedly connected to a third fixing disc 68. The mounting frame 69 is also internally fixedly connected to a second fixing disc 67 and a first fixing disc 66. The surfaces of the second fixing disc 67 and the first fixing disc 66 are provided with through holes. The third fixing disc 68, the second fixing disc 67 and the first fixing disc 66 are internally fixedly connected to syringes 617. There are six syringes 617, and the six syringes 617 are evenly distributed about the axis of the mounting frame 69.

[0027] An electric telescopic rod 65 is fixedly connected to the surface of the first fixed disc 66. An adjusting disc 623 is fixedly connected to the surface of the electric telescopic rod 65. A piston rod 615 is slidably connected inside the syringe 617. A protruding fixing block 616 is fixedly connected to the surface of the piston rod 615. The adjusting disc 623 is slidably connected to the piston rod 615.

[0028] A second telescopic motor 61 is fixedly connected to the surface of the adjusting disc 623. A third fixed block 62 is fixedly connected inside the second telescopic motor 61 through an output shaft. A fourth fixed block 63 is slidably connected inside the adjusting disc 623, and the third fixed block 62 and the fourth fixed block 63 are slidably connected. A rotating plate 64 is rotatably connected inside the adjusting disc 623.

[0029] A third telescopic motor 613 is fixedly connected inside the support base 5. A push rod 614 is fixedly connected inside the third telescopic motor 613 through an output shaft. An electromagnet is provided on the surface of the push rod 614.

[0030] A support disc 620 is fixedly connected to the surface of the mounting cylinder 69. A liquid distributor 618 is fixedly connected to one end of the support disc 620. An input liquid pipe 619 is fixedly connected to the surface of the liquid distributor 618. An electromagnetic control valve 622 is fixedly connected to the other end of the support disc 620. An output liquid pipe 621 is fixedly connected to the surface of the support disc 620.

[0031] In use, firstly, the control panel 2 is used to control the input pipe 619 at the bottom of the liquid distributor 618 to draw in a large amount of liquid. Simultaneously, the control panel 2 is used to start the second telescopic motor 61. The start of the second telescopic motor 61 drives the third fixed block 62 to move towards the mounting bracket 69 via its output shaft. The movement of the third fixed block 62 causes the fourth fixed block 63 to move from inside the adjusting disc 623 to its outer surface. This causes the fourth fixed block 63 to rotate the rotating plates 64, increasing the angle between the rotating plates 64 and facilitating contact between the ends of the rotating plates 64 and the protruding fixed block 616. Then, the control panel 2 is used to control the electric... The telescopic rod 65 drives the adjusting disc 623 to move away from the mounting cylinder 69, thereby causing the rotating plate 64 to move together with the protruding fixed block 616 away from the mounting cylinder 69. This controls the control panel 2 to control the electromagnetic control valve 622 to control the direction of liquid movement into the syringe 617. Subsequently, the output liquid pipe 621, in conjunction with the control panel 2, controls the electromagnetic control valve 622 to activate the electric telescopic rod 65. This causes the electric telescopic rod 65 to drive the piston rod 615 to move in the direction of the supporting disc 620, thereby injecting the liquid inside the syringe 617 into the target body under the control of the liquid distributor 618 and the electromagnetic control valve 622. However, the second telescopic motor 61 can also be activated via the control panel 2. Activation of the second telescopic motor 61 drives the third fixed block 62 away from the mounting frame 69 via its output shaft. This causes the rotating plate 64 to decrease in angle under the spring force. The decrease in angle of the rotating plate 64 causes the fourth fixed block 63 to move towards the center of the adjusting disc 623, preventing the end of the rotating plate 64 from contacting the protruding fixed block 616. Subsequently, the second drive motor 611 is activated via the control panel 2. Activation of the second drive motor 611 drives the cylindrical gear 612 to rotate via its output shaft. The rotation of the cylindrical gear 612 drives the mounting frame 69... The rotation of the mounting cylinder 69 causes the support disc 620 fixed on the surface of the mounting cylinder 69 to rotate, thereby adjusting the position of the syringe 617. Then, the control panel 2 starts the third telescopic motor 613. The start of the third telescopic motor 613 drives the push rod 614 to move in the direction of the protruding fixed block 616 through the output shaft, so that the push rod 614 and the protruding fixed block 616 are magnetically attracted. Then, the control panel 2 further starts the third telescopic motor 613 to move the push rod 614 in the direction of the mounting cylinder 69, so that the liquid inside the single syringe 617 is injected into the target body. With the start of the second telescopic motor 61, a cyclical multi-channel injection is realized.

[0032] By controlling the opening and closing of the electromagnetic control valve 622, the liquid is controlled to enter only from a single output pipe 621, thus moving the liquid in a unidirectional direction. At this time, the control panel 2 can be controlled to start the second telescopic motor 61. The start of the second telescopic motor 61 drives the third fixed block 62 to move in the opposite direction to the mounting bracket 69 via the output shaft. This causes the rotating plate 64 to reduce its angle under the elastic force of the spring. The reduction in the angle of the rotating plate 64 drives the fourth fixed block 63 to move towards the center of the adjusting disc 623, so that the end of the rotating plate 64 does not contact the protruding fixed block 616. Subsequently, the control panel 2 is controlled to start the second drive motor 611. The start of the second drive motor 611 drives the cylindrical gear 612 to rotate via the output shaft. The rotation of the cylindrical gear 612 drives the mounting frame 69 to rotate. The rotation of the mounting frame 69 causes the syringe 617 inside the mounting frame 69 to adjust its position, so that the single syringe 617 containing liquid rotates to a straight line with the push rod 614. Then, the control panel 2 starts the third telescopic motor 613. The start of the third telescopic motor 613 drives the push rod 614 to move in the direction of the protruding fixing block 616 through the output shaft, so that the push rod 614 and the protruding fixing block 616 are magnetically attracted. Then, the control panel 2 further starts the third telescopic motor 613, which drives the push rod 614 and the piston rod 615 to move in the direction of the support disk 620 through the output shaft, so that the liquid inside the single syringe 617 is transferred.

[0033] By setting the first connecting rod 35 and the second rotating disk 36, after starting the first drive motor 33, the first rotating disk 34 and the first connecting rod 35 are rotated. Finally, the second rotating disk 36 drives the first fixed block 37 to vibrate up and down at a high frequency with small amplitude. This causes the air bubbles inside the syringe 617 to detach from their inner wall and move towards the top of the syringe 617, and also breaks the adhesion between the air bubbles and the wall of the syringe 617. This causes the attached air bubbles to detach from the wall and converge into larger air bubbles. Furthermore, the vibration driven by the first fixed block 37 can act evenly on the multi-channel syringe 617, ensuring that the air bubble removal effect of each channel is consistent, which facilitates subsequent discharge and avoids the accumulation of air bubbles inside the syringe 617, thus affecting the injection efficiency of the device.

[0034] By setting a rotating plate 64 inside the adjusting disc 623, the second telescopic motor 61 drives the third fixed block 62 and the fourth fixed block 63 to slide, ultimately changing the included angle between the rotating plate 64. This facilitates the movement of the rotating plate 64 and the protruding fixed block 616, thereby moving multiple piston rods 615 together. This enables the multi-channel syringe 617 to work simultaneously, allowing for batch processing of medicines and significantly improving work efficiency. Furthermore, a push rod 614 is set up. The third telescopic motor 613 drives the push rod 614 to move, thereby fixing the push rod 614 and the protruding fixed block 616 by magnetic attraction. This facilitates the adjustment of individual piston rods 615. The two work together to flexibly cope with complex working conditions and improve the practicality of the device.

[0035] Example 2: Please refer to Figures 1-11 Based on Embodiment 1, the present invention provides a technical solution: The micro-vibration mechanism 3 also includes a first drive motor 33, which is fixedly connected inside the support base 1. The inside of the first drive motor 33 is fixedly connected to the first rotating disk 34 through the output shaft. A second fixing block 38 is slidably connected inside the support base 1. A sliding support plate 31 is fixedly connected to the surface of the second fixing block 38. A buffer spring 32 is fixedly connected inside the support base 1, and the buffer spring 32 is slidably connected to the second fixing block 38.

[0036] The angle adjustment mechanism 4 includes a first telescopic motor 41, which is fixedly connected inside the sliding support plate 31. A second connecting rod 42 is fixedly connected inside the first telescopic motor 41 through an output shaft, and the second connecting rod 42 is rotatably connected to the support base 5.

[0037] The heat dissipation mechanism 7 includes a fixed cylinder 73, which is fixedly connected to the surface of the mounting frame 69. A third drive motor 71 is fixedly connected to the top of the fixed cylinder 73. A fan blade 72 is fixedly connected inside the third drive motor 71 through the output shaft. There are three fixed cylinders 73, and the three fixed cylinders 73 are evenly distributed about the axis of the mounting frame 69.

[0038] In use, after the liquid is drawn into the syringe 617, the control panel 2 is first activated to start the first telescopic motor 41. The activation of the first telescopic motor 41 drives the second connecting rod 42 to extend via the output shaft. The extension of the second connecting rod 42 causes the support base 5 to rotate on top of the sliding support plate 31, thereby adjusting the syringe 617 from a horizontal position to a vertical position. Subsequently, the control panel 2 is activated to start the first drive motor 33. The activation of the first drive motor 33 drives the first rotating disk 34 to rotate via the output shaft. The rotation of the first rotating disk 34 causes the first connecting rod 35 to rotate together. The rotation of the first connecting rod 35 causes the second rotating disk 36 to move up and down. The movement of the second rotating disk 36 causes the first fixed block 37 to move, which in turn causes the sliding support plate 31 to move up and down. The up and down movement of the sliding support plate 31 causes the support base 5 to move up and down, and the movement of the support base 5 causes the liquid inside the syringe 617 to vibrate at a high frequency and a small amplitude, thereby causing the air bubbles attached to the inner wall of the syringe 617 to detach to the top of the syringe 617. Then, the control panel 2 starts the second telescopic motor 61 or the third telescopic motor 613 to drive multiple piston rods 615 or a single piston rod 615 to move in the direction of the support disk 620, so that the gas at the top of the syringe 617 is discharged.

[0039] During the repeated movement of the syringe 617, the control panel 2 starts the third drive motor 71. The start of the third drive motor 71 drives the fan blade 72 to rotate through the output shaft. The rotation of the fan blade 72 continuously ventilates the interior of the mounting frame 69. The cold air flows through the through holes opened on the surfaces of the second fixed disc 67 and the first fixed disc 66, thereby continuously cooling the syringe 617.

[0040] By setting the second connecting rod 42, the first telescopic motor 41 is started and then the second connecting rod 42 drives the support base 5 to rotate, thereby finally adjusting the syringe 617 to the vertical direction. In conjunction with the vibration driven by the first fixing block 37, the air bubbles attached to the inner wall of the syringe 617 are finally condensed into large air bubbles at the top, which facilitates the discharge of air bubbles and improves the working efficiency of the device.

[0041] By setting the fan blade 72, the third drive motor 71 is started and drives the fan blade 72 to rotate, thereby continuously cooling the syringe 617, reducing the temperature of the liquid inside the syringe 617, increasing the solubility of the gas in the liquid, further reducing the generation of bubbles, and the temperature reduction changes the surface tension of the bubbles, weakening the adhesion between the bubbles and the cylindrical gear 612, causing the attached bubbles to detach. Combined with the vibration driven by the first fixing block 37, the debubbling effect is further improved, thereby improving the working efficiency of the device.

[0042] The above description is only a preferred embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any equivalent substitutions or modifications made by those skilled in the art within the scope of the technology disclosed in the present invention, based on the technical solution and inventive concept of the present invention, should be covered within the scope of protection of the present invention.
