[0024] Referring to Figures 1 to 3 As shown in the drawings, according to the liquid filter provided by the embodiment of the application, the tank body 100 is internally provided with a filter element 110, the side wall is provided with a liquid inlet pipe 120, the center of the bottom surface is provided with a liquid outlet 130, and the bottom surface of the tank body 100 is a taper with a large upper part and a small lower part, so as to guide the liquid into the liquid outlet 130. The liquid inlet pipe 120 is arranged along the radial direction of the tank body 100 and towards the filter element 110, the side wall of the liquid inlet pipe 120 is provided with a circular-arc-shaped liquid inlet 121, and the end of the liquid inlet pipe 120 towards the filter element 110 is provided with a flow guide plate 122, and the filter element 110 is located above the liquid outlet 130 to filter the liquid in the tank body 100.

[0025] The adjusting device 200 comprises a circular-arc baffle 210, a support 220 and a magnetic ring 230. The support 220 is connected with the baffle 210, is installed in the liquid inlet pipe 120 and can rotate relative to the liquid inlet pipe 120. The support 220 is provided with magnets and a hollow part 221 through which the medicinal liquid passes. The magnets are provided in plurality and are installed on the side wall of the support 220 along the circumference of the support 220. The baffle 210 is located on the inner side or the outer side of the liquid outlet 130 (hereinafter, the baffle 210 is taken as an example for description, and it is particularly stated that the description will not be repeated hereinafter). The circular-arc baffle 210 can shield at least part of the liquid inlet 121. The magnetic ring 230 is sleeved on the liquid inlet pipe 120 and can rotate relative to the liquid inlet pipe 120. The magnetic ring 230 is rotated to drive the baffle 210 to rotate through the magnets, so as to adjust the opening size of the liquid inlet 121 in the circumference of the liquid inlet pipe 120.

[0026] It can be understood that, by arranging the flow guide plate 122, the flow guide plate 122 can limit the medicinal liquid in the liquid inlet pipe 120 from directly impacting the filter element 110, so that the medicinal liquid flows out from the liquid inlet 121 of the side wall of the liquid inlet pipe 120, reduces the loss of the filter element 110 and prolongs the service life of the filter element 110. By arranging the adjusting device 200, the user rotates the magnetic ring 230, the magnetic ring 230 drives the magnets to rotate, and then drives the support 220 and the baffle 210 to rotate. At this time, the baffle 210 rotates relative to the liquid inlet 121, so as to adjust the opening size of the liquid inlet 121 in the circumference of the liquid inlet pipe 120. The user can adjust the opening size of the liquid inlet 121 according to different viscosities of the medicinal liquid. For example, when the viscosity of the medicinal liquid is high, the user can rotate the baffle 210 away from the position of the liquid inlet 121 to increase the flow at the liquid inlet 121, so that the medicinal liquid quickly flows into the tank body 100 for filtration. When the viscosity of the medicinal liquid is low, the user can rotate the baffle 210 to shield the liquid inlet 121 to reduce the flow at the liquid inlet 121, so as to avoid the problems such as rapid accumulation of the medicinal liquid, increase of the load of the filter element 110 and rapid increase of the pressure in the tank body 100. The filter element 110 can efficiently filter medicinal liquids with different viscosities, effectively improve the filtration efficiency and improve the practicability of the medicinal liquid filter.

[0027] Further, the tank body 100 comprises a tank body 140 and a base 150. The tank body 140 and the base 150 are sealingly connected through a sanitary clamp 160. A gasket is further arranged between the tank body 140 and the base 150. The liquid inlet pipe 120 is arranged on the side wall of the tank body 140, and the liquid outlet 130 is arranged at the center of the base 150. Optionally, the inner diameter of the gasket can be smaller than the outer diameter of the support 220, so as to limit the support 220 in the radial direction of the liquid inlet pipe 120 and improve the installation stability of the support 220.

[0028] Still further, the top end of the tank body 100 is provided with an end cover 141. The end cover 141 is welded with an air outlet 142.

[0029] By setting the gas outlet 142, high-pressure gas can be discharged from the tank body 100 during the liquid medicine accumulation process, avoiding safety accidents caused by pressure accumulation in the tank body 100, and improving the use safety of the liquid medicine filtering device.

[0030] Referring to Figure 1 It can be understood that the distance between the liquid inlet pipe 120 and the top surface of the tank body 100 is less than the distance between the liquid inlet pipe 120 and the bottom surface of the tank body 100, in other words, the liquid inlet pipe 120 is located in the lower half of the tank body 100.

[0031] The liquid inlet pipe 120 is arranged at a position close to the base 150 of the tank body 100, which reduces the height of the tank body 100 and facilitates the arrangement of the pipe body when the liquid inlet pipe 120 is connected to the pipe body, thereby improving the assembly convenience of the liquid medicine filtering device.

[0032] Referring to Figures 2 to 4 It can be understood that the support 220 includes a star-shaped framework 222 and a connecting rod 223, the star-shaped framework 222 is composed of a block in the center and a plurality of supports distributed on the peripheral wall of the block, and a hollow part 221 for the liquid medicine to pass through is formed between the adjacent two frameworks, the outer peripheral wall of the star-shaped framework 222 abuts against the inner peripheral wall of the liquid inlet pipe 120, the star-shaped framework 222 is connected with the baffle 210 through the connecting rod 223, the star-shaped framework 222 is provided with a plurality of mounting grooves 2221, and each mounting groove 2221 is inlaid with a magnet. Optionally, the connecting rod 223 can be welded and fixed with the star-shaped framework 222 and the baffle 210, or can be screw-connected, clamped, inserted, or adhesively fixed with the star-shaped framework 222 and the baffle 210, and the connection structure of the connecting rod 223 with the star-shaped framework 222 and the baffle 210 is not specifically limited as long as the star-shaped framework 222 can stably drive the baffle 210 to rotate.

[0033] By setting the star-shaped framework 222, the magnets can be arranged and installed conveniently without affecting the flow of the liquid medicine, the mass of the support 220 can be reduced, the resistance of the magnetic ring 230 can be reduced, and the use convenience of the adjusting device 200 can be improved.

[0034] In some embodiments, the star-shaped framework 222 can also be replaced by a circular plate member provided with through holes, thereby facilitating the design and processing of the support 220.

[0035] Further, the star-shaped framework 222 is an integrally formed member. Optionally, the star-shaped framework 222 can be an integrally formed alloy member by casting or turning, or an integrally formed high-strength plastic member by injection molding.

[0036] When the liquid medicine filter is in operation, the star-shaped framework 222 is subjected to radial pressure caused by the impact of the liquid medicine, and when the user rotates the magnetic ring 230 to control the rotation of the baffle 210, the star-shaped framework 222 is subjected to circumferential pressure caused by the resistance of the liquid medicine. The star-shaped framework 222 is provided as an integral molded part, which can effectively improve the overall strength of the star-shaped framework 222, improve the impact resistance and shear resistance of the star-shaped framework 222, and prolong the service life of the star-shaped framework 222.

[0037] With reference to Figure 3 As shown in the figure, it can be understood that the connecting rod 223 includes a rotating shaft part 2231, which extends in a direction away from the support 220 and is rotationally connected with the flow guide plate 122, that is, the end of the connecting rod 223 is inserted into the blind hole on the flow guide plate 122, and a small section of the rod body at the middle end branch of the connecting rod 223 is connected with the baffle 210.

[0038] By providing the rotating shaft part 2231, on the one hand, the rotating shaft part 2231 is rotationally connected with the flow guide plate 122, and the flow guide plate 122 can limit the support 220 in the radial direction of the liquid inlet pipe 120, further improving the installation stability of the support 220; on the other hand, the rotating shaft part 2231 can support and guide the rotation of the connecting rod 223, effectively improving the rotation stability of the support 220.

[0039] Further, the baffle 210 is provided with two, and the two baffles 210 are symmetrically arranged on both sides of the connecting rod 223.

[0040] Providing two baffles 210 can reduce the original 360° adjustment angle of the baffle 210 to two same 180° adjustment angles, reduce the adjustment angle of the baffle 210, facilitate the user to adjust and use, and improve the user's experience.

[0041] It should be noted that when the interval between the two baffles 210 is small and the liquid outlet 130 is large, the gap between the two baffles 210 can move in the liquid outlet 130, at this time, the liquid medicine outlet amount does not change with the rotation of the baffle 210, but the liquid medicine outlet angle changes with the rotation of the baffle 210, thereby improving the flexibility of the adjusting device 200.

[0042] With reference to Figure 4 As shown in the figure, it can be understood that in the circumferential direction of the liquid inlet pipe 120, the central angle a of the liquid inlet 121 is greater than the central angle β of the baffle 210.

[0043] The central angle alpha of the inlet 121 is set to be greater than the central angle beta of the baffle 210, that is, the baffle 210 does not completely block the inlet 121, and the inlet 121 always has an opening for the liquid medicine to flow out, thereby avoiding the problems of the inlet pipe 120 being blocked, pressure being accumulated in the inlet pipe 120, and the like, caused by the baffle 210 of the user blocking the inlet 121, and prolonging the service life of the inlet pipe 120.

[0044] Further, the baffle 210 and the inlet pipe 120 are made of the same material.

[0045] The baffle 210 and the inlet pipe 120 are made of the same material, so that the baffle 210 can be formed by secondary processing of the processing waste of the inlet pipe 120, thereby reducing the material cost of the liquid medicine filtering device.

[0046] Obviously, the above embodiments of the utility model are only examples for clearly illustrating the utility model, and are not intended to limit the embodiments of the utility model. For those skilled in the art, various obvious changes, re-adjustments and substitutions can be made without departing from the protection scope of the utility model.
