[0012] Preferably, a push plate is fixed to the top of the slider extending to the outside of the slide groove, and an anti-slip ring is sleeved on the outside of the push plate. Through the setting of the push plate, a larger force-bearing area can be created between the push plate and the operator's hand, so that the user can hold it and apply force more easily, thereby achieving the purpose of speeding up the assembly or disassembly operation.

[0013] Preferably, a second spring is also fixed to one end of the slider, and the second spring is fixed in the slide groove relative to one end of the slider; through the setting of the second spring, the second spring is tightened and reset, thereby giving the push plate a thrust toward one side of the clamping block, making it easier for the clamping block to fit tightly along the clamping groove.

[0024] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0025] The utility model provides Figure 1 A liquid medicine negative pressure filtering mechanism shown includes:

[0026] A filter tank 1, a top end of the filter tank 1 is provided with a liquid guide port 12 connected to the inside thereof, a buffer tank 11 is installed at the bottom end of the filter tank 1, and a first filter screen 13 is installed in the filter tank 1; the structure of the buffer tank 11 and its specific negative pressure principle are both prior art, and specific reference is made to the comparative document (publication number CN216457293U, and the patent name is a liquid medicine vacuum filtration device), which will not be repeated here;

[0027] As can be seen from the above, when the medicinal liquid is filtered under negative pressure, the medicinal liquid flows into the interior of the filter tank 1 from the liquid inlet 12, and is used to filter impurities contained in the medicinal liquid through the first filter screen 13, so that the filtered medicinal liquid flows into the buffer tank 11, and the air inside the buffer tank 11 is extracted, thereby forming a negative pressure in the buffer tank 11, so as to speed up the flow of the medicinal liquid in the filter tank 1 into the slow flushing tank 11, which is convenient for subsequent processing of the medicinal liquid.

[0028] refer to Figure 1-Figure 3 As shown, the filter assembly 2 includes a second filter screen 21 installed in the filter tank 1 and baffles 22 installed at both ends of the second filter screen 21, and the second filter screen 21 is located directly below the liquid guide port 12, a sliding cavity is formed between the two baffles 22 and the filter tank 1, and a reciprocating assembly for driving the two baffles 22 to move is provided on the filter tank 1;

[0029] The reciprocating assembly includes a driving motor 27 fixed to one side of the filter tank 1 and a guide post 23 fixed to one side of the baffle 22, and one end of the guide post 23 passes through the filter tank 1 and is fixed with a contact ring 26, and one end of the driving motor 27 is fixed with an eccentric ring 28 that matches the contact ring 26, and a positioning assembly is provided in the filter tank 1 to limit the filter tank 1 and the baffle 22;

[0030] The positioning assembly includes a first spring 25 fixed in the filter tank 1 and a spring slot 24 opened on one side of the baffle 22 , and the spring slot 24 and the first spring 25 are fixedly connected.

[0031] Through the above technical solution:

[0032] When the liquid medicine is filtered under negative pressure, the impurities in the liquid medicine are first filtered through the second filter screen 21, so that the impurities are left on the surface of the second filter screen 21. At the same time, the driving motor 27 drives the eccentric ring 28 to rotate synchronously, so that the outer protruding part of the eccentric ring 28 and the abutment ring 26 abut against each other during the rotation of the eccentric ring 28, which is used to push one of the guide pillars 23. However, during the movement of one of the guide pillars 23, the baffle plate 22 and the second filter screen 21 are pushed to move in the direction of the force. As the baffle plate 22 is pushed to move along the filter tank 1, the other guide pillar 23 is pushed synchronously. Since the baffle plate 22 stretches one of the first springs 25 when it moves again, the other first spring 25 is located at the second filter screen 21 and the filter tank 1 are compressed, and when the eccentric ring 28 rotates, the friction between the external protrusion and the resistance ring 26 disappears, and then the first spring 25 itself is elastically reset to make the resistance ring 26 and the eccentric ring 28 fit tightly, waiting for the next eccentric ring 28 to resist the resistance ring 26, thereby moving the second filter screen 21 back and forth along the filter tank 1, so that the second filter screen 21 shakes during the continuous change of position, reducing the blockage of the second filter screen 21 by impurities, so that the impurities in the liquid medicine can be filtered and removed, thereby solving the problem that the existing filter paper has a small mesh and is prone to blockage, which makes the filter paper prone to poor circulation, and saves time and effort, thereby improving the filtration efficiency of the liquid medicine.

[0033] In addition, refer to Figure 1 , Figure 2 and Figure 4 As shown, the baffle plate 22 is provided with a cleaning assembly 3 for removing the second filter screen 21, and the cleaning assembly 3 includes a connecting plate 31 fixed to one end of the second filter screen 21 and a supporting groove 32 provided on the top of the baffle plate 22 for the connecting plate 31 to be inserted into, and a locking assembly is provided on the connecting plate 31 to stabilize it with the supporting groove 32; the locking assembly includes a clamping groove 34 provided on one side of the supporting groove 32 and a clamping block 33 installed on one end of the connecting plate 31, and the clamping block 33 is clamped and fixed with the clamping groove 34, and a sliding groove is provided at the top of the connecting plate 31, and a slider 35 is slidably connected in the sliding groove, and one end of the clamping block 33 penetrates into the sliding groove and is fixedly connected to one side of the slider 35; the top of the slider 35 extends to the outside of the sliding groove and is also fixed with a push plate 36, and the outside of the push plate 36 is sleeved with an anti-slip ring; one end of the slider 35 is also fixed with a second spring 37, and the second spring 37 is fixed in the sliding groove relative to one end of the slider 35.

[0034] Through the above technical solution:

[0035] When the liquid medicine is filtered under negative pressure, the filter tank 1 is first opened to expose the second filter screen 21 to the user's field of vision, and the push plate 36 is pushed to make the push plate 36 move the slider 35 installed at its bottom along the through groove, and then the clamping block 33 is pulled to move synchronously during the movement of the slider 35. At this time, the second spring 37 is located in the slider 35 and the slide groove and is compressed, and the clamping block 33 moves along the clamping groove 34 in the direction of the force, so that the clamping block 33 is disengaged from the clamping groove 34, which is used to lose the fixation between the connecting plate 31 and the supporting groove 32, so that the second filter screen 21 can be quickly taken out from the filter tank 1, reducing the difficulty of the operator to take it out, and at the same time facilitating the operator to replace or clean it, preventing the situation where the filtering effect is reduced due to long-term use, and facilitating the cleaning of liquid medicine impurities on the second filter screen 21, thereby improving the filtering efficiency of the liquid medicine.
