[0050] See also Figures 1 to 5 This embodiment provides a rapid dosing device, including a frame 10, a clamping mechanism, a plurality of dosing mechanisms 30 and a driving mechanism 40.

[0051] The clamping mechanism is used to hold multiple vessels 20 containing water samples and can intermittently rotate on the frame 10. Multiple dosing mechanisms 30 are distributed along the circumference and are located above the clamping mechanism. These dosing mechanisms 30 can drip medication into the corresponding vessels 20 on the clamping mechanism. A drive mechanism 40 is used to drive the rotation of the clamping mechanism and drive the dosing mechanisms 30 to drip medication into the vessels 20.

[0052] In this embodiment, the clamping mechanism rotates intermittently under the drive mechanism 40. When the clamping mechanism stops rotating, the inspector places the vessels 20 containing water samples one by one. Simultaneously, the dosing mechanism 30 above, driven by the drive mechanism 40, drips the chemicals into the vessels 20 below. As the clamping mechanism rotates one full circle, the vessels 20 on the clamping mechanism pass under multiple dosing mechanisms 30, allowing the same vessel 20 to be dripped with multiple chemicals. The inspector only needs to place the vessel 20 containing the water sample onto the clamping mechanism on one side of the device and remove the vessel 20, already dripped with multiple chemicals, from the clamping mechanism, saving time and effort.

[0053] In one embodiment, the frame 10 includes a base 11; the clamping mechanism includes a clamping ring 50 rotatably mounted on the base 11; the clamping ring 50 is provided with a plurality of clamping holes 51 distributed along its circumference; the clamping holes 51 are used to place and support the vessel 20. Specifically, a coaxial bearing is provided at the lower end of the clamping ring 50, the outer ring of the bearing being connected to the clamping ring 50, and the inner ring of the bearing being connected to the base 11, thereby enabling the clamping ring 50 to rotate on the base 11. The vessel 20 can be a glass container with an outwardly flared upper end. The lower end of the vessel 20 is placed above the clamping hole 51, and the upper end of the vessel 20 is restrained by the clamping hole 51 and cannot move further downward, thereby maintaining the vessel 20 within the clamping hole 51.

[0054] In one embodiment, the drive mechanism 40 includes a driven rod 42 and a drive cylinder 41. The drive cylinder 41 is rotatably mounted within the center of a clamping ring 50. The drive cylinder 41 is coaxial with the clamping ring 50 and can move up and down. The outer wall of the drive cylinder 41 is provided with circumferentially arranged guide grooves. One end of the driven rod 42 is connected to the inner ring of the clamping ring 50, and the other end of the driven rod 42 is elastically retractable and inserted into the guide groove. The elastic retraction of the driven rod 42 can be referred to in the prior art.

[0055] The guide grooves include multiple pairs of groove groups 43 distributed along the circumference of the driving cylinder 41. The multiple pairs of groove groups 43 are connected in sequence.

[0056] The groove group 43 includes vertical grooves 431 and inclined grooves 432 .

[0057] The upper end of the vertical groove 431 is a shallow end, and the lower end of the vertical groove 431 is a deep end. The upper end of the inclined groove 432 is a deep end, and the lower end of the inclined groove 432 is a shallow end.

[0058] The shallow end of each vertical groove 431 communicates with the deep end of each inclined groove 432 in the adjacent groove group 43, and the shallow end of each vertical groove 431 is less than the deep end of each inclined groove 432. The deep end of each vertical groove 431 communicates with the shallow end of each inclined groove 432 in the adjacent groove group 43, and the deep end of each vertical groove 431 is greater than the shallow end of each inclined groove 432. Multiple groove groups comprise multiple pairs of vertical grooves 431 and inclined grooves 432, and within each pair of vertical grooves 431 and inclined grooves 432, the vertical grooves 431 and inclined grooves 432 are spaced apart.

[0059] In this embodiment, Figure 3 When the driving cylinder 41 moves downward, the end of the driven rod 42 moves upward along the vertical groove 431, that is, from the deep end of the vertical groove 431 to the shallow end of the vertical groove 431, until the end of the driven rod 42 reaches the upper end (deep end) of the inclined groove 432. Because the upper end of the inclined groove 432 is deeper than the upper end of the vertical groove 431, there is a step between the inclined groove 432 and the vertical groove 431 at this location. At this time, when the driving cylinder 41 moves upward, the driven rod 42 moves along the inclined groove 432, from the deep end of the inclined groove 432 to its shallow end, until it enters the deep end (lower end) of the vertical groove 431 of the adjacent groove group. As the driving cylinder 41 moves up and down, the driven rod 42 drives the clamping ring 50 to rotate.

[0060] In one embodiment, the driving mechanism 40 further includes an electric push rod 44 and a driving rod 45

[0061] The electric push rod 44 is arranged on the base 11. The driving rod 45 is arranged vertically, and the driving rod 45 is connected to the output end of the electric push rod 44 and is coaxially connected to the driving cylinder 41.

[0062] In this embodiment, the electric push rod 44 drives the driving cylinder 41 to move up and down through the driving rod 45.

[0063] In one embodiment, the rack 10 further includes a back plate 12 and a support frame 13 .

[0064] The back plate 12 is connected to the base 11 , and the support frame 13 is connected to the base 11 . The support frame 13 is located above the base 11 .

[0065] The drug adding mechanism 30 includes an outer cylinder 31 , a drug guiding tube 32 , a drug injection cylinder 33 , a drug pushing column 34 , a connecting rod 35 and a tapered piston 36 .

[0066] The upper and lower ends of the outer cylinder 31 are both closed. The outer cylinder 31 is vertically arranged and connected to the support frame 13. A coaxial mounting hole 311 is opened at the upper end of the outer cylinder 31, and a coaxial dosing hole 312 is opened at the lower end of the outer cylinder 31.

[0067] The drug guiding tube 32 is located below the outer tube 31 and is coaxially connected to the lower end of the outer tube 31. The drug guiding tube 32 is connected to the inner cavity of the outer tube 31. The drug injection cylinder 33 is located inside the outer tube 31 and is connected to the inner wall of the lower end of the outer tube 31. The drug injection cylinder 33 is connected to the drug guiding tube 32.

[0068] The lower end of the charge pushing column 34 slides through the mounting hole 311 and can be inserted into the drug injection barrel 33. The upper end of the charge pushing column 34 is connected to the drive rod 45. The charge pushing column 34 is dynamically sealed with the mounting hole 311. The connecting rod 35 is connected to the lower end of the charge pushing column 34. The conical piston 36 is coaxially connected to the lower end of the connecting rod 35. The conical piston 36 can be inserted into the drug injection barrel 33. The upper end of the charge pushing column 34 is provided with an air guide channel 341 extending along its axial direction. The side wall of the charge pushing column 34 is provided with an air guide hole 342 along its radial direction. The air guide hole 342 is connected to the air guide channel 341. When the conical piston 36 moves downward and is inserted into the drug injection barrel 33, the air guide hole 342 moves into the outer barrel 31.

[0069] In this embodiment, the driving rod 45 can drive the medicine pushing column 34 to move up and down, and the outer cylinder 31 is filled with medicine. When the medicine pushing column 34 moves downward, the connecting rod 35 drives the conical piston 36 to be inserted into the medicine injection cylinder 33. The conical piston 36 and the medicine injection cylinder 33 form a syringe barrel, and the external medicine guide tube 32 is a syringe needle. At this time, the air guide hole 342 on the medicine pushing column 34 is located in the outer cylinder 31 after passing through the mounting hole 311, and the outer cylinder 31 is connected to the outer cylinder 31 through the air guide channel 341. The medicine pushing column 34 moves further downward, and the conical piston 36 completes the injection in the medicine injection cylinder 33, and the medicine in the medicine injection cylinder 33 is pushed into the vessel 20 below through the medicine guide tube 32.

[0070] When the medicine column 34 is pushed upward, before the conical piston 36 leaves the medicine injection barrel 33, the air guide hole 342 has moved upward and passed the mounting hole 311, thereby isolating the air in the outer barrel 31 from the outside. Even if the conical piston 36 leaves the medicine injection barrel 33, the medicine will not flow out of the medicine injection barrel 33.

[0071] The driving rod 45 moves up and down once, the lower clamping ring 50 rotates an angle, the upper dosing mechanism 30 adds medicine once, and the medicine guiding tube 32 corresponds to a different container 20 each time.

[0072] In one embodiment, a connecting ring 37 is provided on the inner wall of the lower end of the outer tube 31; the lower end of the injection barrel 33 is threadedly connected to the inner ring of the connecting ring 37. Specifically, the injection barrel 33 has different lengths and specifications. By replacing different injection barrels 33, the amount of drug injected each time can be changed, thereby meeting the requirements of different drug addition amounts during water sample testing.

However, it is understood that the embodiments of the present invention can be practiced without these specific details. In some instances, well-known methods, structures and techniques are not shown in detail so as not to obscure the understanding of this specification.
