Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0028] Example 1.

[0029] like Figures 1-4 As shown, this embodiment provides a digestion vessel tray for a microwave digester, including a lower fixing ring 1. Eight elastic pins 2 are evenly arranged circumferentially on the inner ring of the lower fixing ring 1. An upper tray 3 is provided on the upper part of the lower fixing ring 1, and the lower fixing ring 1 is fixedly connected to the upper tray 3. Multiple digestion vessel insertion holes 4 are provided on the upper tray 3. The lower fixing ring 1 is sleeved on the outside of the rotating disk 5 of the microwave digester. Eight positioning grooves 6 are evenly arranged circumferentially on the outer ring of the rotating disk 5 of the microwave digester. Pin insertion holes 7 are provided inside the positioning grooves 6. The positioning grooves 6 correspond one-to-one with the elastic pins 2. One end of the elastic pin 2 is fixedly connected to the inner ring of the lower fixing ring 1. The other end of the elastic pin 2 is hemispherical and fits into the pin insertion hole 7. The digestion vessel insertion hole 4 is an upward-opening regular hexagonal recessed hole.

[0030] The upper tray has multiple digestion vessel insertion holes, allowing multiple digestion vessels to be inserted into them. The digestion vessel tray facilitates the simultaneous relocation of multiple digestion vessels, resulting in high testing efficiency. The lower fixing ring is located at the bottom of the upper tray and is fixedly connected to the upper tray. The inner ring of the lower fixing ring can be fitted over the rotating disk. The digestion vessel tray allows for the simultaneous installation and removal of multiple digestion vessels and the rotating disk, making operation convenient.

[0031] The elastic ejector pins are arranged radially along the lower fixing ring, with eight elastic ejector pins evenly distributed around the inner circumference of the lower fixing ring. The digestion vessel tray is stably connected to the rotating disk, and the digestion vessel tray rotates together with multiple digestion vessels and the rotating disk. One end of the elastic ejector pin is hemispherical. When the digestion vessel tray is pressed down, and the hemispherical end of the elastic ejector pin aligns with the ejector pin insertion hole, the elastic ejector pin is inserted into the ejector pin insertion hole. When the digestion vessel tray is lifted upward, the elastic ejector pin is squeezed by the wall of the ejector pin insertion hole, and the digestion vessel tray is detached from the rotating disk. This design facilitates the installation and removal of the digestion vessel tray.

[0032] The specific operation steps of the above-mentioned microwave digestion instrument with a digestion tank tray are as follows:

[0033] (1) The digestion tank tray is placed flat on the operation table, and the digestion tank is inserted into the digestion tank insertion hole after being loaded with materials;

[0034] (2) The digestion tank tray is placed into the box body of the microwave digestion instrument, and the lower fixed ring is sleeved outside the rotating disc inside the box body of the microwave digestion instrument;

[0035] (3) The elastic ejector pin corresponds to the positioning groove of the rotating disc, and the digestion tank tray is pressed downward, and when the hemispherical end of the elastic ejector pin corresponds to the upper ejector pin insertion hole, the hemispherical end of the elastic ejector pin is inserted into the ejector pin insertion hole;

[0036] (4) Under the fixation of the eight elastic ejector pins, the digestion tank tray is stably connected with the rotating disc, and the digestion tank tray rotates together with the rotating disc;

[0037] (5) When the digestion tank tray needs to be taken off from the rotating disc, the digestion tank tray is lifted upward, and under the extrusion of the ejector pin insertion hole wall, the elastic ejector pin is extruded, and the digestion tank tray is separated from the rotating disc.

[0038] In order to firmly insert the digestion tank into the digestion tank tray, the digestion tank insertion hole is an upper-opened regular hexagonal concave hole, and a silica gel sleeve can be sleeved outside the digestion tank. The silica gel sleeve cooperates with the digestion tank insertion hole, the regular hexagonal concave hole and the silica gel sleeve are tightly combined, the digestion tank can be firmly inserted into the digestion tank insertion hole, and it is ensured that the digestion tank does not rotate in the digestion tank insertion hole.
