[0028] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0029] The present invention will be further described below with reference to embodiments.

[0030] Please see Figures 1-6 The technical solution provided by this invention is as follows: it includes a battery 1, a linear motor 2, an MCU, a button 3, an injection switch 4, and a display screen 5. The battery 1 provides power to the linear motor 2, the MCU, the button 3, and the display screen 5. The button 3 is electrically connected to the MCU to control the linear motor 2 to achieve process and speed adjustment. The display screen 5 is electrically connected to the MCU to display the adjustment content of the button 3 and the injection data. The injection switch 4 is electrically connected to the MCU to control the motor to perform injection.

[0031] When using this invention, the power button 206 is pressed and held to turn on the syringe, which then enters the standby state. At this time, the mode setting interface of the linear motor 2 can be entered by pressing the mode button 201, such as injection mode or nebulization mode. Different modes can be set by changing the speed of the linear motor 2, and different injection heads can be matched for use. It has both injection and nebulization modes, making it more widely applicable.

[0032] After setting the mode, the injection parameters can be increased by pressing the plus key 202 to increase the single injection volume, and the injection parameters can be decreased by pressing the minus key 203 to decrease the single injection volume. The injection volume can be adjusted continuously and precisely by adjusting the propulsion stroke of the linear motor 2, which can effectively prevent drug waste and over-administration. The current injection parameters can be displayed intuitively on the display screen 5.

[0033] After adjustment, press the injection switch 4 to drive the linear motor 2 to work, and perform injection work at the set stroke and speed. The linear motor 2 pulls back the piston 14 to achieve negative pressure liquid aspiration, and pushes the piston 14 forward to achieve injection. Continuous injection can be achieved through the continuous operation of the linear motor 2, thereby improving injection efficiency, effectively reducing manual labor and labor costs. The injection record can be viewed on the display screen 5 by pressing the query key 205.

[0034] The injection process only requires holding the syringe and pressing the injection switch 4. No hand squeezing is required. Inject according to the set dosage. Changing the hand control method makes it more precise. At the same time, when the linear motor 2 pulls back the piston 14, the needle tip can be aligned with the next injection target. This allows for continuous injection by utilizing the drug absorption time, reducing waiting time and speeding up injection efficiency. It is suitable for large-scale livestock farms.

[0035] The needle head is connected to the needle via a Luer locking element, allowing for flexible and quick needle replacement. The syringe 13 can also be replaced with a suitable size to meet injection needs.

[0036] refer to Figure 3The MCU is powered by a 3.3V power supply. Capacitors C6, C7, and C8 are used for power filtering to stabilize the power supply voltage. The PC14 and PC15 pins are connected to an external crystal oscillator to provide a clock signal for the MCU. The SWDIO and SWCLK pins are used to connect a debugger to enable program downloading and debugging.

[0037] refer to Figure 4 This circuit is mainly used for key 3 input detection, battery voltage detection, and motor control signal output.

[0038] Button 3 is connected to a 3.3V power supply via a pull-up resistor. When button 3 is pressed, the signal line is grounded, and the MCU microcontroller identifies the input of button 3 by detecting the level change of the signal line.

[0039] The battery voltage (VBAT) is divided by a resistor divider circuit and then connected to the ADC pin of the MCU microcontroller to realize the detection of battery voltage.

[0040] The MCU_485_RXD and MCU_485_TXD pins of the MCU are used for receiving and sending control signals for linear motor 2.

[0041] refer to Figure 5 This circuit is a 3.3V power conversion and screen interface circuit, used to convert battery voltage to 3.3V power and provide an interface for the screen.

[0042] The TPSPX3819M5-L-3-3 chip is used to convert the battery voltage (VBAT) to 3.3V to power subsequent circuits.

[0043] Display 5 Interface: Connects to the screen via SDA and SCL pins to enable communication with Display 5. The PWR_3.3V_EN signal is used to control the use of the 3.3V power supply.

[0044] refer to Figure 6 This circuit is a charging and conversion circuit for battery 1, used to convert the battery voltage of battery 1 into a stable 24V power supply and provide charging control functions.

[0045] The battery charging control is achieved through a circuit composed of components such as Q1, SD15C, and R1, and the PWR_BAT signal is used to control the charging process.

[0046] The battery voltage (VBAT) is converted to 24V using the MT3608 chip. The output voltage is set by resistors R2 and R4, and the formula is VOUT = VREF * (1 + R2 / R4), where VREF = 0.6V.

[0047] It also includes a housing 12 and an injection cylinder 13. The battery 1 is installed at the handle of the housing 12. The linear motor 2 is installed inside the housing 12. The MCU and circuit board are installed inside the housing 12 behind the linear motor 2. The button 3 and the display screen 5 are installed on the top of the housing 12. The injection switch 4 is installed on the front side of the handle of the housing 12 and is electrically connected to the linear motor 2 through a connecting wire.

[0048] The linear motor 2 and circuit boards and other electrical components are reasonably installed in the effective space inside the housing 12, making the internal structure compact and orderly, which is conducive to inspection and maintenance, while achieving a more comfortable and aesthetically pleasing handheld appearance.

[0049] A piston 14 is installed inside the syringe 13, and the piston 14 is connected to a linear motor 2 via a drive rod 15. The linear motor 2 moves the drive rod 15 back and forth, realizing the pushing and pulling of the piston 14, which is more precise and efficient, and the drug delivery process is uniform and stable.

[0050] A bottle holder 16 is connected above the syringe 13, and a bottle insert 17 is installed inside the bottle holder 16. The bottle insert 17 is used to connect the medicine bottle and deliver the internal medicine liquid into the syringe.

[0051] When the piston 14 is pulled back, the space between the syringe 13 and the piston 14 gradually increases, thereby drawing the liquid medicine in the inverted vial inserted in the vial holder 16 into the space between the syringe 13 and the piston 14 through the vial insert 17. During this process, the one-way valve at the injection section is closed. When the piston 14 is pushed out, the one-way valve at the connection between the vial insert 17 and the syringe 13 is closed, thus enabling normal injection. Based on this, the continuous drug aspiration and injection process is realized.

[0052] The housing 12 is internally fixed with a motor end cover 18 and a motor rear cover 19. The linear motor 2 is installed between the motor end cover 18 and the motor rear cover 19. The motor rear cover 19 is provided with heat dissipation holes. This facilitates the stable installation and smooth operation of the linear motor 2 and improves the overall drop resistance of the device.

[0053] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions will not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention.
