[0025] In this embodiment: when medicine or food enters the crushing chamber 402, the first motor 401 drives the crushing rod 403 to rotate, thereby causing the crushing blade 404 to crush the medicine or food. After crushing, the solenoid valve 405 is opened, allowing the crushed medicine or food to fall onto the screen 406 for sieving. Particles that meet the size requirements will fall into the dilution tank 1, while those that do not meet the size requirements will remain on the top of the screen 406. The user can open the door on one side of the processing chamber 3 to collect the unqualified food or medicine particles and put them back into the crushing chamber 402 for crushing.

[0026] As a technical optimization of this utility model, the connecting mechanism 6 includes a connecting ring 601, which is fixed to one side of the dilution tank 1. A sealing gasket 602 is provided on the side of the connecting ring 601 away from the dilution tank 1, and a sealing disc 603 is provided on the side of the sealing gasket 602 away from the connecting ring 601. A first connecting block 604 is fixedly connected to the outer side of the connecting ring 601, and a second connecting block 605 is fixedly connected to the outer side of the sealing disc 603. A connecting bolt 606 is provided in the inner cavity of the second connecting block 605.

[0027] In this embodiment: when inspecting the inside of the dilution tank 1 or disassembling the dilution mixing mechanism 7, the user can unscrew the nut on the outside of the connecting bolt 606, and then pull the connecting bolt 606 out from the first connecting block 604 and the second connecting block 605, so that the sealing plate 603 can be removed from one side of the dilution tank 1.

[0028] As a technical optimization of this utility model, the dilution mixing mechanism 7 includes a second motor 701, which is installed on one side of the sealing disk 603.

[0033] The working principle of the dilution device for testing solid food and pharmaceuticals provided by this utility model is as follows:

[0034] When using this device, medicines or food can be fed into the crushing chamber 402 through the feed pipe 5. After the medicines or food enter the crushing chamber 402, the first motor 401 drives the crushing rod 403 to rotate, thereby causing the crushing blade 404 to crush the medicines or food. After crushing, the solenoid valve 405 is opened, allowing the crushed medicines or food to fall onto the screen 406 for sieving. Particles of the correct size will fall into the dilution tank 1. Then, the user can connect the inlet pipe of the metering pump 2 to an external water supply pipe, and the metering pump 2 will deliver water to the dilution tank 1. By setting the metering pump 2, the user can adjust the setting according to the current amount of medicine or food being fed. The water supply is controlled by the user. The mixing rod 702 is rotated by the second motor 701, and the medicine or food in the dilution tank 1 is mixed with water by the mixing blade 704. The diluted sample can be discharged through the outlet pipe 8. When inspecting the inside of the dilution tank 1 or disassembling the dilution mixing mechanism 7, the user can unscrew the nut on the outside of the connecting bolt 606 and then pull the connecting bolt 606 out from the first connecting block 604 and the second connecting block 605. The sealing plate 603 can then be removed from one side of the dilution tank 1. At this time, the user can unscrew the nut on the outside of the fixing bolt 705 and then separate the mixing blade 704 from the fixing seat 703, which makes it easy for the user to replace the mixing blade 704.
