[0016] The following further describes the utility model with reference to the drawings.

[0017] As shown in Att Figure 1 , a sample oscillating water bath digestion device includes a water bath box 1 and a box lid 2. An electric hot plate 3 is attached to the outer bottom of the water bath box 1; a container rack 5 for placing a sample container 4 is arranged inside the water bath box 1, and the sample container 4 is vertically slidably arranged; an upper elastic member 7 is arranged on the inner cover surface of the box lid 2, a lower elastic member 8 is arranged at the bottom of the container rack 5, and the sample container 4 is in a state of being elastically suspended in the solution through the clamping cooperation of the upper elastic member 7 and the lower elastic member 8, so that the sample container 4 vibrates up and down under the push of the boiling solution in the water bath box 1. The utility model uses the thrust of the boiling solution to push the sample container elastically suspended in the solution, causing it to vibrate. Without the need to additionally provide a vibration mechanism, it achieves the purpose of preventing the container lid from being pushed out by clamping while improving the uniformity of the water bath digestion of the sample, ensuring the normal progress of the water bath digestion operation of the sample.

[0018] More specifically, as shown in Att Figure 3 , the sample container 4 is vertically slidably arranged relative to the container rack 5 through a guide sleeve 6 in a corresponding container position 50. The guide sleeve 6 is composed of balls arranged on the inner side wall of the sleeve body, reducing the friction of the vibration movement of the sample container 4 and making it more flexible.

[0019] As shown in Att Figure 3As shown, the container rack 5 is composed of a bottom plate 52 with vertical plates 53 provided on both sides to support a top plate 51. The bottom plate 52 is fixedly attached to the inner bottom of the water bath tank 1. A number of container positions 50 are evenly distributed on the top plate 51, and a number of through holes 5a are provided on the top plate 51 to facilitate the flow of the solution through the through holes 5a. At the same time, while ensuring the structural strength, the vertical plates 53 can also be provided with holes to form a hollow shape for the solution.

[0020] As shown in the appendix Figure 2 As shown, the upper elastic member 7 and the lower elastic member 8 have the same structure, and are both composed of a spring 9 with end blocks 10 connected to both ends respectively; among them: in the upper elastic member 7, the upper end block 10 is connected to the box cover 2, and the lower end block 10 is embedded in the upper card slot 110 provided at the top of the container cover 11 of the sample container 4; in the lower elastic member 8, the lower end block 10 is connected to the bottom plate 52, and the upper end block 10 is embedded in the lower card slot 40 provided at the bottom of the sample container 4. The fitting and installation of the card slot and the end block 10 are for the temporary connection during the water bath digestion operation of the upper elastic member 7 and the lower elastic member 8 respectively, to prevent the upper elastic member 7 and the lower elastic member 8 from tilting and deviating to disengage from the elastic clamping of the sample container 4.

[0021] To facilitate the embedding of the end block 10, the entrances of the upper card slot 110 and the lower card slot 40 are both in an expanded shape, and chamfering treatment can be carried out for simplicity.

[0022] To increase the driving force of the sample container 4 by the boiling solution, a flat plate 12 extending outward is provided on the side of the sample container 4. In the present utility model, the flat plate 12 is preferably an annular plate surrounding the outer periphery of the sample container 4.

[0023] The above are only the preferred embodiments of the present utility model. It should be noted that: for those of ordinary skill in the art in this technical field, without departing from the principle of the present utility model, several improvements and refinements can be made, and these improvements and refinements should also be regarded as the protection scope of the present utility model.
