Detailed implementation manners

[0027] The present utility model will be described in detail below with reference to the drawings and in conjunction with embodiments.

[0028] As Figure 1 、 Figure 2 and Figure 3 shown, a decoction liquid filtering device for traditional Chinese medicinal materials includes a connecting sleeve 1 and a first filter sheet 2 and a second filter sheet 3 arranged therein. The first filter sheet 2 and the second filter sheet 3 are respectively detachably connected to the connecting sleeve 1, and the first filter sheet 2 is located above the second filter sheet 3. The connecting sleeve 1 is a conical sleeve with a large port facing upward, and it is made of stainless steel. The second filter sheet 3 is a medical gauze filter sheet, and the first filter sheet 2 is a stainless steel filter sheet or a resin filter sheet and has a spherical panel structure. The filtering area of the first filter sheet 2 is its middle and lower part, and there is a distance from the edge of the first filter sheet 2 in this area, and a number of filter holes 25 are densely arranged in this area. In this device, the connecting sleeve 1 is arranged as a conical sleeve, which is convenient for it to be stably inserted into the cup mouth of the cup, facilitating the operation of separating the medicinal residues and improving the stability of the medicinal residue separation operation. The first filter sheet 2 and the second filter sheet 3 achieve secondary filtering of the medicinal liquid, improving the filtering effect. At the same time, since the first filter sheet 2 and the connecting sleeve 1 are detachably connected, it is convenient to pour the filter residues on the second filter sheet 3.

[0029] The detachable connection structure between the first filter sheet 2 and the connecting sleeve 1 is as follows: An annular platform 12 is integrally formed on the inner wall of the connecting sleeve 1 corresponding to the first filter sheet 2. As Figure 4 shown, the inner diameter of the inner circle of the annular convex platform 12 corresponds to the diameter of the second filter sheet 3. Four positioning holes 121 are vertically opened in the annular platform 12, and the four positioning holes 121 are evenly arranged in the circumferential direction. A fixing eaves 22 is provided at the edge of the first filter sheet 2. Handles 21 are respectively arranged upward at the left and right ends of the top surface of the fixing eaves 22 for facilitating the holding of the first filter sheet 2. Four positioning pins 23 are integrally formed on the bottom surface of the fixing eaves 22. The four positioning pins correspond to the four positioning holes 121 one by one. The annular platform 12 supports the fixing eaves 22, and the positioning pins 23 are movably inserted into the corresponding positioning holes 121 to stabilize the first filter sheet 2.

[0030] In the present utility model, the filtering area of the first filter sheet 2 is arranged in its middle and lower regions, so that the medicinal liquid filtered by the first filter sheet flows towards the second filter sheet 3 as much as possible from the middle position. To improve the stability during the filtering of the medicinal liquid and prevent the situation where when the amount of the poured medicinal liquid is too large or the speed is too fast, the medicinal liquid occupies all the filter holes 25, resulting in the inability to discharge the air in the medicine cup and causing poor flow of the medicinal liquid, the first filter sheet 2 is provided with exhaust holes 24 near its edge position. Thus, the air in the medicine cup is discharged sequentially through the second filter sheet 3 and the exhaust holes 24 of the first filter sheet 2, making the air pressure in the medicine cup balanced with the external air pressure and ensuring the stable filtering of the medicinal liquid by the first filter sheet 2.

[0031] In the present utility model, the detachable connection structure between the second filter sheet 3 and the connecting sleeve 1 is as follows: the second filter sheet 3 is tightened and clamped by two fixing rings 31 arranged oppositely up and down. The fixing rings 31 are preferably made of hard plastic or resin, and the second filter sheet is fixed by hot melting. An annular groove is formed on the bottom surface of the lower fixing ring 31. The lower edge of the connecting sleeve 1 is integrally formed with an inner eaves 13. As Figure 4 shown, several clamping protrusions 131 are evenly arranged in the circumferential direction on the upper surface of the inner eaves 13, and the clamping protrusions 131 are clamped into the annular groove, thereby fixing the second filter sheet 3.

[0032] In the present utility model, the upper edge of the connecting sleeve 1 is provided with an outer eaves 11 to facilitate grasping the connecting sleeve 1 for taking and placing operations.

[0033] When applying the present utility model to filter the medicinal liquid, the connecting sleeve 1 is inserted into the cup mouth of the medicine cup 4. As Figure 5 shown, since the connecting sleeve 1 is a conical sleeve, it can be stably inserted and connected to the cup mouth of the medicine cup. Pour the decocted medicinal liquid into the present utility model, and the medicinal liquid is filtered sequentially through the first filter sheet 2 and the second filter sheet 3, realizing the separation of the medicinal residues and obtaining a relatively pure medicinal liquid.

[0034] The above are only the preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principle of the present utility model shall be included within the protection scope of the present utility model.
