By providing the cleaning device, the material stuck in the filter screen is effectively cleaned, which plays a role in cleaning the material stuck in the filter screen, reduces the possibility that the raw materials are easily stuck in the mesh of the filter screen when the equipment is in use, causing damage to the filter screen and making it difficult to filter the raw materials, thereby improving the practicality of the equipment.

[0015] 2. In the utility model, a dispersion device is provided. When the device is in use, the user pulls the card block, and the card block moves, driving the spring to displace and deform to generate elastic force. The card block then moves out of the inside of the groove, and the connecting column loses its restraint, and the moving connecting column is separated from the inside of the feed port.

By providing a dispersion device, the raw materials entering the main body are effectively dispersed, and the raw materials are spread flat on the surface of the filter screen. This reduces the situation where the user adds the raw materials into the main body through the feed port when the device is in use, and the raw materials are easily accumulated on the surface of the filter screen, making it difficult for the device to quickly filter and screen the raw materials, thereby improving the practicality of the device.

By setting up the dispersion device 7, the raw materials entering the inside of the main body 1 are effectively dispersed, and the raw materials are spread flat on the surface of the filter screen 5. This reduces the situation that when the device is in use, the user adds the raw materials into the inside of the main body 1 through the feed port 2, and the raw materials are easily accumulated on the surface of the filter screen 5, making it difficult for the device to quickly filter and screen the raw materials, thereby improving the practicality of the device.
