[0017] In order to deepen the understanding of the present invention, the present invention will be further described in detail below in conjunction with embodiments. The embodiments are only used to explain the present invention and do not constitute a limitation on the scope of protection of the present invention.

[0018] according to Figure 1-3 As shown, this embodiment proposes a compact infusion valve that is easy to adjust, including an infusion valve body 1, an infusion valve front cover 2 and a speed control mechanism. An infusion tube bayonet groove 3 is provided in the middle of the front of the infusion valve body 1, a first mounting groove 4 is provided on the infusion valve body 1 on one side of the infusion tube bayonet groove 3, and a speed control mechanism is provided in the first mounting groove 4. A second mounting groove 5 is provided on the infusion valve body 1 above the first mounting groove 4, and an infrared sensor 6 is provided inside the second mounting groove 5. The infusion valve body 1 can be detachably mounted with an infusion tube bayonet groove 3 on the front. The liquid valve front cover 2 is provided with a display screen 7 above the front of the infusion valve front cover 2. The speed regulation result is displayed through the display screen 7. The display screen 7 displays the current dripping rate in real time. A groove 8 is provided on the infusion valve front cover 2 below the display screen 7. A speed increase button 9 and a speed decrease button 10 are provided in the groove 8. An alarm 11 is provided below the front of the infusion valve body 1; the speed regulation control mechanism includes an electric push rod 12 and a speed regulating valve plate 13. The electric push rod 12 is provided in the first mounting groove 4, and the speed regulating valve plate 13 is provided at the output end of the electric push rod 12.

[0019] A main control chip is also provided inside the main body 1 of the infusion valve of the present invention. The main control chip is electrically connected to the alarm 11 , the display screen 7 , the infrared sensor 6 and the controller of the electric push rod 12 . When the compact infusion valve that is easy to adjust of the present invention is installed and used, the infusion hose is placed inside the infusion tube bayonet slot 3, and then the infusion valve body 1 and the infusion valve front cover 2 are connected. When speed adjustment is needed, the speed-up button 9 or the speed-down button 10 is used to increase or decrease the speed. After the speed-up button 9 or the speed-down button 10 is pressed, the main control chip will send a signal to the controller of the electric push rod 12, and then the controller will control the electric push rod 12 to move, thereby driving the speed-regulating valve plate 13 to loosen or compress the infusion hose to realize dripping rate control. During the process, the infrared sensor 6 monitors the flow rate and feeds back the main control chip to accurately send a signal to control the electric push rod 12 to extend and retract the stroke; when the infrared sensor 6 detects the dripping empty phenomenon, it directly feeds back a signal to the main control chip, and the main control chip will send a signal to directly control the electric push rod 12 to extend and drive the speed-regulating valve plate 13 to compress the infusion hose, thereby adjusting the dripping rate to 0. At the same time, the main control chip detects a signal and sends an alarm to the alarm 11 for an alarm prompt.

[0020] Limit rods 14 are symmetrically positioned above and below one side of the speed regulating valve plate 13. A socket 15 is provided within the infusion tube bayonet slot 3 to align with the position of the limit rods 14. One end of the limit rod 14 is positioned within the socket 15. By providing the limit rods 14 on one side of the speed regulating valve plate 13, the infusion hose can be threaded between the limit rods 14, ensuring that the speed regulating valve plate 13 can accurately control the dripping rate of the infusion hose.

[0021] Positioning posts 16 are provided at the four inner corners of the infusion valve front cover 2, and positioning holes 17 are provided at the four front corners of the infusion valve body 1, which mate with the posts 16. Multiple fixing bolts 18 are provided on the front of the infusion valve front cover 2, and screw holes 19 are provided on the front of the infusion valve body 1. The positioning posts 16 and positioning holes 17 facilitate quick assembly and positioning of the infusion valve front cover 2 with the infusion valve body 1. The combination of the fixing bolts 18 and screw holes 19 allows for a quick and stable connection of the assembled and positioned infusion valve front cover 2 to the infusion valve body 1.

[0022] A battery slot 20 is provided on one side of the infusion valve body 1, and the battery slot 20 is adapted to the position of the first mounting slot 4. A battery is provided in the battery slot 20. The battery supplies power to all electrical units in the infusion valve of the present invention.

[0023] A cover plate 21 is slidably mounted within the groove 8. A toggle slot is provided at one end of the cover plate 21. A first magnetic sheet is mounted at one end of the cover plate 21, and a second magnetic sheet that mates with the first magnetic sheet is mounted at one end of the groove 8. The cover plate 21 seals the groove 8, preventing the user from accidentally touching the speed-up button 9 and the speed-down button 10. To increase or decrease speeds using the speed-up button 9 and the speed-down button 10, the user can simply pull the entire cover plate 21 at the toggle slot to separate the first and second magnetic sheets.

[0024] The utility model configures the infusion valve to consist of an infusion valve body 1, an infusion valve front cover 2 and a speed control mechanism, and provides an infrared sensor 6, a display screen 7, an increase speed button 9, a decrease speed button 10 and an alarm 11. The infrared sensor 6 can be used to monitor the flow rate in the infusion hose, and then the speed control mechanism can be used to control the flow rate based on the monitoring, and the dripping rate can be accurately controlled by the increase speed button 9 and the decrease speed button 10. The infrared sensor 6 of the utility model can also use the alarm 11 to alarm when a dripping phenomenon is detected, thereby improving convenience and safety in use.
