[0027] Through the above technical solution, when it is necessary to filter the medicine, first open the sealing cover 213, and pour the medicine or solution to be tested into the second filter frame 208 through the feed frame 212 and the funnel 211. Under the action of gravity, the medicine or solution will be filtered through the coarse filter element 210, the activated carbon layer 207 and the fine filter element 206 in sequence. The coarse filter element 210 can remove larger impurities and particles, the activated carbon layer 207 is used to adsorb harmful substances and odors, and the fine filter element 206 further removes tiny particles and impurities. After triple filtration, the pure medicine or solution will flow into the support tube 201 and the mixing pipe 1. When the filtration is completed, the liquid in the mixing pipe 1 can be discharged by opening the switch valve 304 in the discharge pipe 303. During the discharge process, it is necessary to ensure that the operation of the switch valve 304 is flexible and reliable. In order to avoid liquid leakage or poor discharge, and to maintain the performance of the filter and extend its service life, the filter needs to be cleaned regularly. When cleaning, the filter mechanism 2 can be removed from the mixing pipe 1 first, and then each component can be cleaned separately, especially the fine filter element 206, the activated carbon layer 207 and the coarse filter element 210. They need to be carefully cleaned and the impurities and dirt attached to them are removed. After cleaning, the various components can be reinstalled. Through triple filtration of the coarse filter element 210, the activated carbon layer 207 and the fine filter element 206, the filter can efficiently remove impurities and harmful substances in medicines or solutions and improve the filtering effect. The components are connected by threads and bolts, which makes disassembly and reinstallation very convenient, which not only simplifies the cleaning and maintenance process, but also reduces maintenance costs and time costs.

[0028] Specifically, a fixing ring 214 is fixedly connected to the outer side of the top of the first filter frame 204 and the outer side of the bottom of the second filter frame 208. Bolts are set in the fixing ring 214. The top of the first filter frame 204 and the bottom of the second filter frame 208 are attached and fixedly connected by the bolts in the fixing ring 214.

[0033] Through the above technical solution, three groups of filtering mechanisms 2 are provided, and these three groups of filtering mechanisms 2 are distributed in a linear array at the top of the mixing pipe 1, which improves the filtering efficiency because more filtering mechanisms 2 can process more drug inspection samples at the same time. At the same time, the linear array distribution also makes the entire filter structure more compact and orderly.

[0034] Specifically, the support mechanism 3 includes a support plate 301 , a rubber pad 302 is bonded to the bottom of the support plate 301 , a discharge pipe 303 is fixed to the right side of the support plate 301 , and a switch valve 304 is provided in the discharge pipe 303 .

[0035] Through the above technical solution, the support mechanism 3 is installed in a suitable position, and the support plate 301 is in close contact with the ground or workbench through the rubber pad 302 at its bottom to ensure stable support. At the same time, the rubber pad 302 also plays a certain shock-absorbing and anti-slip role, providing stable support and avoiding problems such as liquid leakage and machine vibration.

[0036] Specifically, two support plates 301 and two rubber pads 302 are provided, and the inner sides of the two support plates 301 are fixedly connected to the left and right sides of the mixing pipe 1 respectively.

[0037] Through the above technical solution, two support plates 301 and two rubber pads 302 are provided, and the inner sides of the two support plates 301 are fixedly connected to the left and right sides of the mixing pipe 1 respectively. The addition of the rubber pad 302 not only increases the stability of the support mechanism 3, but also reduces the friction and vibration between the mixing pipe 1 and the support plate 301, thereby extending the service life of the filter.

[0038] Specifically, the left side of the discharge pipe 303 passes through the support plate 301 and is connected to the right side of the mixing pipe 1 .

At the same time, the rubber pad 302 also plays a certain shock-absorbing and anti-slip role. When it is necessary to filter the medicine, first open the sealing cover 213, and pour the medicine or solution to be tested into the second filter frame 208 through the feed frame 212 and the funnel 211. Under the action of gravity, the medicine or solution will be filtered through the coarse filter element 210, the activated carbon layer 207 and the fine filter element 206 in turn. The coarse filter element 210 can remove larger impurities and particles, the activated carbon layer 207 is used to absorb harmful substances and odors, and the fine filter element 206 further removes tiny particles and impurities. After triple filtration, the pure medicine or solution will flow into the support tube 201 and the mixing pipe 1 When the filtration is completed, the liquid in the mixing pipe 1 can be discharged by opening the switch valve 304 in the discharge pipe 303. During the discharge process, it is necessary to ensure that the operation of the switch valve 304 is flexible and reliable to avoid liquid leakage or poor discharge. In order to maintain the performance of the filter and extend its service life, the filter needs to be cleaned regularly. When cleaning, the filter mechanism 2 can be first removed from the mixing pipe 1, and then each component can be cleaned separately, especially the fine filter element 206, the activated carbon layer 207 and the coarse filter element 210. They need to be carefully cleaned and the impurities and dirt attached to them are removed. After cleaning, the various components can be reinstalled. Through triple filtration of the coarse filter element 210, the activated carbon layer 207 and the fine filter element 206, the filter can efficiently remove impurities and harmful substances in medicines or solutions and improve the filtration effect.
