Description

Technical Field

[0001] The utility model belongs to the technical field of water bath pots, in particular to a water bath digestion device that prevents boiling solution from mixing into samples. Background Art

[0002] During the process of water bath heating digestion of samples in a water bath, the container cover of the sample container is easily ejected by the top thrust of the continuously heated boiling solution and separated from the sample container, causing the solution to enter the sample container and mix with the sample, resulting in failure of the sample water bath digestion process. Summary of the invention

[0003] Purpose of the invention: In order to overcome the deficiencies in the prior art, the utility model provides a water bath digestion device that prevents boiling solution from mixing into samples. The container cover is pressed and positioned by a pressing cover member on the sealing cover, which can prevent the container cover from spraying out of the sample container due to continuous heating of the boiling solution, thereby preventing the solution from mixing into the sample.

[0004] Technical solution: To achieve the above-mentioned purpose, the utility model provides a water bath digestion device for preventing boiling solution from mixing into samples, comprising a water bath body, on which a plurality of water bath ports are arranged side by side, and corresponding water bath ports are provided with sealing covers and a container seat located in the water bath body; a pressure cover member is vertically movably provided on the sealing cover, and the pressure cover member can move downward relative to the sealing cover of the water bath port to abut against the container cover of the sample container located on the container seat.

[0005] Furthermore, the cover pressing member comprises an elastic telescopic pressure rod portion which is threadedly penetrated through the sealing cover, and the elastic telescopic pressure rod portion presses the container cover when it is screwed into the sealing cover.

[0006] Furthermore, a screw handle is arranged at the top end of the elastic telescopic pressure rod portion, and a pressure plate is arranged at the bottom end, and the pressure plate is arranged against the container cover.

[0007] Furthermore, a card slot is arranged on the inner side of the cover, and a card block corresponding to the card slot is arranged on the inner edge of the water bath opening, and the cover is covered on the water bath opening through the card slot and the card block.

[0008] Furthermore, a heating component and a support frame located above the heating component are provided in the water bath body, and the container seat is fixedly supported by the support frame.

[0009] Furthermore, the container seat is a groove-shaped structure seat whose inner structure contour is matched with the outer structure contour of the sample container, and its opening is in an expanded shape, and the bottom and side surfaces are in a hollow structure shape.

[0010] Beneficial effects: In the present utility model, the container lid is press-positioned by the pressing member on the sealing cover, and the pressing force for press-positioning offsets the top thrust applied to the container lid due to the boiling of the solution, thereby being able to avoid the container lid being ejected from the sample container due to continuous heating and the solution boiling, resulting in the solution mixing into the sample, and ensuring the normal progress of the sample water bath digestion operation. Description of the Drawings

[0011] Appendix Figure 1 is a schematic structural view of the water bath pot of the present utility model in a cut-away state;

[0012] Appendix Figure 2 is Figure 1 an enlarged schematic structural view of the container lid of the sample container in the press-positioned state in Appendix;

[0013] Appendix Figure 3 is a schematic structural view of the sealing cover and the pressing member thereon. Detailed Embodiment

[0014] The following further describes the present utility model with reference to the drawings.

[0015] As shown in Appendix Figure 1 and Appendix Figure 2 A water bath digestion device for preventing boiling solution from mixing into the sample includes a water bath pot body 1, a plurality of water bath ports 2 are arranged side by side on the water bath pot body 1, a sealing cover 3 and a container seat 8 located inside the water bath pot body 1 are provided corresponding to the water bath ports 2; a pressing member 4 is vertically movably arranged on the sealing cover 3, and the pressing member 4 can move downward relative to the sealing cover 3 of the water bath port 2 to abut against the container lid 6 of the sample container 5 sitting on the container seat 8. In the present utility model, the container lid 6 is press-positioned by the pressing member 4 on the sealing cover 3, and the pressing force for press-positioning offsets the top thrust applied to the container lid 6 due to the boiling of the solution, thereby being able to avoid the container lid 6 being ejected from the sample container 5 due to continuous heating and the solution boiling, resulting in the solution mixing into the sample, and ensuring the normal progress of the sample water bath digestion operation.

[0016] As shown in Appendix Figure 2 and Appendix Figure 3 The pressing member 4 includes an elastic telescopic pressing rod portion that threadedly penetrates the sealing cover 3, and the elastic telescopic pressing rod portion elastically presses the container lid 6 in the state of screwing into the sealing cover 3. A screwing handle 41 is provided at the top end of the elastic telescopic pressing rod portion, and a pressing plate 42 is provided at the bottom end, and the pressing plate 42 abuts against the container lid 6. More specifically, the elastic telescopic pressing rod portion includes an upper screw rod 43, a lower regular prism rod 44 and a spring 45. The upper screw rod 43 is threadedly connected through the container lid 6, the lower regular prism rod 44 is telescopically connected with the upper screw rod 43, the spring 45 is sleeved on the lower regular prism rod 44, and both ends of the spring 45 are respectively connected with the upper screw rod 43 and the pressing plate 42. The advantages of the pressing member 4 with such a structure are as follows:

[0017] Advantage 1: By adopting the threaded screwing method, when opening or closing the cover 3, holding the screwing handle 41 by hand will not cause the elastic telescopic pressure rod part to rotate, making it easier to operate;

[0018] Advantage 2: The buffer force for pressing and positioning the container cover 6 can be increased through the spring 45. Compared with direct pressing and other methods, the impact force on the container cover 6 is relatively small due to buffering, avoiding damage to the container cover 6 and the sample container 5 during pressing and positioning.

[0019] A clamping groove 30 is provided on the inner edge side of the cover of the cover 3, and a clamping block 20 corresponding to the clamping groove 30 is provided on the inner edge of the water bath port 2. The cover 3 is covered on the water bath port 2 through the clamping fit of the clamping groove 30 and the clamping block 20, which has the advantages of directly pressing and clamping when installing the cover 3 and directly pulling out and disengaging the clamp when disassembling the cover 3.

[0020] A heating component 7 and a support frame 9 located above the heating component 7 are provided in the water bath pot body 1, and the container seat 8 is fixedly supported by the support frame 9. The heating component 7 is a heating pipe, and the support frame 9 is formed by intersecting and welding metal rods. The edge of the support frame 9 is connected to the inner wall of the water bath pot body 1.

[0021] The container seat 8 is a trough-shaped structure seat whose inner structural contour is adapted to the outer structural contour of the sample container 5, and its opening is in an expanded shape, facilitating the placement of the sample container 5. The bottom and side surfaces are in a hollow structure shape, and evenly distributed through holes 80 are provided through the bottom and side surfaces of the container seat 8, facilitating the water bath heating of the sample container 5 by the solution in the water bath pot body 1.

[0022] The above is only the preferred embodiment of the present invention. It should be noted that for those of ordinary skill in the art, without departing from the principle of the present invention, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present invention.
