[0027] As attached Figure 1 To the attached Figure 6 As shown:

[0028] Example 1: According to Figure 1 - Figure 4 As shown, the present invention provides a device for automatically dispensing oral contrast agents, comprising a storage cylinder 1, an upper bracket 2 being installed on the outer side of the top end of the storage cylinder 1, a supporting leg rod 3 being provided on the outer side of the bottom end of the storage cylinder 1, and an infusion tube 4 being further provided in the middle of the top end of the storage cylinder 1;

[0029] The weighing and unloading mechanism is arranged on the inner side of the infusion tube 4, and the weighing and unloading mechanism includes a storage tank 5, which is installed on the top of the infusion tube 4. The inner side of the upper bracket 2 is snap-connected with the storage tank 5, and the top of the storage tube 1 is also installed with a water injection pipe 6. A telescopic cylinder 7 is installed in the middle of the inner side of the upper bracket 2, and the output end of the telescopic cylinder 7 is fixedly connected to the telescopic rod 8, and the outermost end of the telescopic rod 8 is fixedly connected to the weighing module 10. The outer side wall of the infusion tube 4 is fixedly connected with a connecting sleeve 9, and the connecting sleeve 9 is also sleeved on the outer side of the weighing module 10 for sealing between the infusion tube 4 and the weighing module 10. The inner side wall of the infusion tube 4 is rotatably connected with a closing plate 14, and a drive motor 13 is installed on the inner side of the upper bracket 2. The output end of the drive motor 13 is fixedly connected to the closing plate 14 The storage cylinder 1 is fixedly connected together, a driving motor 13 is installed at the bottom end of the storage cylinder 1, and the output end of the driving motor 13 is fixedly connected to a closing plate 14. A water injection pipe 6 is installed at one end of the top of the storage cylinder 1, and the infusion pipe 4 and the water injection pipe 6 inject material into the storage cylinder 1 through the top of the storage cylinder 1. A water outlet pipe 11 is installed on the outer wall of the bottom end of the storage cylinder 1, and a water outlet switch 12 is installed on the top and inner side of the water outlet pipe 11. The weighing module 10 is connected to the control module through a wire, and the output end of the control module is also connected to the driving motor 13 and the telescopic cylinder 7. The driving motor drives the closing plate to rotate in both directions to realize the three-stage automatic control of "powder-liquid mixing → finished product stirring → emptying and cleaning", and the mixing uniformity is improved by more than 40%. The storage tank is directly connected to the infusion pipe through the weighing module to form a closed material transmission path to avoid powder dust pollution.

[0030] Example 2: According to Figure 1 、 Figure 5 and Figure 6 As shown, the bottom end of the supporting leg rod 3 is fixedly connected to a connecting slot 15, and the outer side of the connecting slot 15 is slidably connected to a connecting sleeve 16. A baffle is provided near the front end of the connecting slot 15 to close the connecting sleeve 16 to prevent it from falling out. The bottom end of the connecting sleeve 16 is fixedly connected to a bottom support rod 17, and two anti-slip pads 18 are fixedly connected to both sides of the top of the bottom support rod 17. The two anti-slip pads 18 are also slidably connected to the bottom end of the supporting leg rod 3;

[0031] By connecting the anti-skid pad 18 to the support leg rod 3, the support leg rod 3 and the anti-skid pad 18 can be connected together by the gravity of the storage cylinder 1 itself after the leg rod is stretched or retracted, thereby avoiding sliding.

[0032] Working principle: When the device is needed, first place the device where it is needed, then pull the bottom support rod 17 to allow the bottom support rod 17 to slide out with the connecting sleeve 16 in the connecting slot 15. After sliding out, the gravity of the storage cylinder 1 allows the anti-slip pad 18 to fit tightly with the supporting leg rod 3 to avoid reset after moving out. Then, different contrast agents are stored in the storage tank 5 respectively. When the raw material needs to be injected into the storage cylinder 1, the control module will first control the drive motor 13 to work, allowing the drive motor 13 to rotate with the closing plate 14. Then, when the weighing module 10 reaches the appropriate weight, it will transmit the signal. Give it to the control module, let the control module control the driving motor 13 and the telescopic cylinder 7 to work, the driving motor 13 will drive the closing plate 14 to rotate back to block the infusion tube 4, and then the telescopic cylinder 7 will slide with the weighing module 10 through the telescopic rod 8, so that the contrast agent on the top of the weighing module 10 will go down, and the contrast agent will enter the storage cylinder 1 and water will be injected into the storage cylinder 1 through the water injection pipe 6. Then the driving motor 13 will drive the closing plate 14 to work, so that the closing plate 14 will stir the water and contrast agent. The mixed contrast agent can be taken out through the water outlet switch 12 and the water outlet pipe 11, and water will be injected into the storage cylinder 1 again through the water injection pipe 6, and the closing plate 14 can be rotated to clean the storage cylinder 1.
