The present invention will be further explained with reference to the drawings and examples.
The whole sectional structure of the filtering device for microwave extraction of the utility model is shown in figure 1, and the filtering device comprises an upper fixing seat 1-3, a lower fixing seat 1-1, and a filtering plate 1-2 arranged between the upper fixing seat and the lower fixing seat.
The filter plate 1-2 is arranged between the upper fixed seat 1-3 and the lower fixed seat 1-1.
The upper fixing seat is a cylindrical structure with two open ends, and a first rotary buckle structure is arranged at the lower part of the cylindrical structure; the lower fixing seat is of a short cylindrical, circular or upward-opening circular cap-shaped structure, and a second rotary buckle structure is arranged at the upper end of the short cylindrical, circular or upward-opening circular cap-shaped structure; the lower fixed seat is rotatably arranged at the lower end of the upper fixed seat; at least one liquid passing groove is formed in the lower end face of the lower fixed seat;
the filter device is integrally assembled and then placed in the inner cavity of the microwave extraction cup to form a solid-liquid separation/filtration structure.
The first rotary buckle structure and the second rotary buckle structure can adopt an external thread-internal thread structure (at the moment, the upper fixed seat is equivalent to a screw rod, the lower fixed seat is equivalent to a nut, and the first rotary buckle structure and the second rotary buckle structure can generate screwing or unscrewing actions through rotation); a screw-buckle structure similar to that of a can with an iron cover can also be adopted (at the moment, the upper fixed seat is equivalent to a can body, the lower fixed seat is equivalent to an iron cover of the can, and the upper fixed seat and the lower fixed seat rotate to generate screwing or unscrewing actions); an internal thread-external thread structure can also be adopted (at the moment, the upper fixed seat is equivalent to a nut, the lower fixed seat is equivalent to a screw rod, and the upper fixed seat and the lower fixed seat are rotated to generate screwing or unscrewing actions).
The first rotary buckle structure and the second rotary buckle structure are arranged between the upper fixing seat and the lower fixing seat, so that the upper fixing seat and the lower fixing seat can be screwed into a whole through screwing action, and the filter plate is clamped and fixed between the upper fixing seat and the lower fixing seat; on the contrary, the upper fixing seat and the lower fixing seat can be conveniently separated through the unscrewing action between the upper fixing seat and the lower fixing seat, so that the filter plate can be conveniently disassembled, assembled and replaced, or the filter device can be conveniently cleaned.
Based on the same principle, other screwing structures capable of generating screwing or unscrewing actions can be adopted, and the same technical effects can be generated.
The upper fixing seat 1-3 is fastened with the lower fixing seat 1-1 through a first screwing structure and a second screwing structure (taking a thread structure as an example in the figure), so that the whole filtering device is assembled, and is simple and easy to operate.
If the filter plate 1-2 needs to be cleaned or replaced, the filter plate 1-2 can be taken out only by unscrewing the thread structure between the lower fixed seat 1-1 and the upper fixed seat 1-3.
A plurality of liquid passing grooves 1-1-1 are uniformly arranged on the periphery of the side surface of the lower end of the lower fixed seat 1-1, and the upper end of the upper fixed seat 1-3 is provided with a lifting hole 1-3-1 and a hanging lug 1-3-2.

During the extraction process, the extraction liquid 5 flows out of the filter plate 1-2 first, while the solid sample 4 remains in the filter device 1 without any contamination of the extraction liquid 5.
The excessive extract 5 can pass through the liquid passing groove 1-1-1 and be stored between the outer wall of the filtering device 1 and the inner wall of the microwave extraction cup 2, so that the collection time of the extract is reduced.
After the microwave extraction is finished, the sample 4 still contains the extract 5 which is not dripped, and the extract 5 is collected continuously in order to improve the recovery rate.
Obviously, in the extraction process of sample microwave, the filtering device of the technical scheme actually forms a solid-liquid separation/filtering structure, completely separates the solid sample from the liquid extraction liquid, and can provide convenience for the concentration and analysis of the subsequent extraction liquid.
As shown in figure 3, the upper end of the upper fixed seat 1-3 of the invention is provided with a lifting hole 1-3-1 and a hanging lug 1-3-2.

After the filtering device 1 is lifted out of the microwave extraction cup 2, the filtering device is rotated by a certain angle, the hangers 1-3-2 avoid the abdicating groove 2-1 and then are placed at the upper edge of the microwave extraction cup 2, and the extraction liquid 5 can be continuously collected.
As shown in FIG. 4, after collection of extract 5, filter apparatus 1 is lifted out of microwave extraction cup 2, and solid sample 4 and extract 5 are completely separated. Then, the extract 5 in the microwave extraction cup 2 can be conveniently subjected to subsequent treatments such as concentration, analysis and the like.
After the technical scheme is adopted, the whole extraction liquid collecting process does not need an additional collecting container or any tool for clamping a filtering device, reduces the pollution generated by transferring the extraction liquid and the loss of the sample extraction liquid 5, and is simple and easy to implement.
