[0022] The vacuum mechanism is also included, which is used to exhaust the gas in the shell 4 and prevent the raw materials from being discharged with the gas. The vacuum mechanism includes an air pump 15 installed on the left wall of the side plate 2 on the left side. The air inlet pipe of the air pump 15 is connected to the air delivery pipe 11. The left side of the side plate 2 on the right side is fixedly connected with a second connecting column 12. The left end of the second connecting column 12 passes through the corresponding sleeve 3, the shell 4, and the first hollow sphere 8 and is fixedly connected with a second hollow sphere 13. The upper end of the second hollow sphere 13 is as shown in FIG. Figure 4As shown, a circular inner groove is opened, and an arc-shaped brush 17 is arranged on the front side of the second hollow sphere 13. The arc-shaped brush 17 is a soft brush made of artificial fiber material. The arc-shaped brush 17 fits the inner wall of the first hollow sphere 8. When it contacts the inner wall of the first hollow sphere 8, it is in a bent state, and when it contacts the multiple circular filter holes, it is in an extended state.
