The bottom of the fixed column 1 is equipped with a supporting bottom column 5, and the outer side of the supporting bottom column 5 is also covered with a rotating drum 4. The placement component 3 includes a connecting fence 31, a placement rack 32 and a pressure sensing switch The gate 33 has three parts, and the dry powder fire extinguisher 9 is placed in the placement rack 32, the connecting guardrail 31 is fixedly connected to the left side of the rotating drum 4, and the right side of the connecting guardrail 31 is the placement rack 32, the pressurizing component 6 includes a fixed collar 61, a booster pump 62, a lifting groove 63, an extension rod 64, a pressure plate 65 and an inflation head 66, the fixed collar 61 is installed on the outside of the fixed column 1, and the fixed collar 61 is also connected to the lifting motor 2, the booster pump 62 is arranged on the fixed collar 61, and the lower end of the fixed collar 61 is also equipped with an extension rod 64, the bottom of the extension rod 64 is connected to the pressure plate 65, and the pressure plate 65 is arranged with an inflation head 66, and the inflation head 66 is connected to the booster pump 62 through the extension rod 64.

[0020] As the first embodiment of the utility model: the pressure sensing switch 33 is the control switch of the lifting motor 2, and the pressure sensing switch 33 is installed at the bottom of the placement rack 32. This design uses the weight of the dry powder fire extinguisher 9 to control the lifting of the lifting motor 2, which is convenient for improving the pressurization efficiency of the dry powder fire extinguisher 9, and has a high degree of automation. The size of the inflation head 66 matches the size of the air inlet 10 at the top of the dry powder fire extinguisher 9. This design inflates and pressurizes the air inlet 10 through the inflation head 66. The structure is reasonable and simple. A rubber pad is added to the bottom of the placement rack 32, and The overall size of the placement rack 32 meets the size of the dry powder fire extinguisher 9. The design enhances the stability of the dry powder fire extinguisher 9 when placed on the placement rack 32 by adding a rubber pad. The pressure plate 65 is welded to the bottom of the extension rod 64, and the inflation head 66 can be placed. The design uses the pressure plate 65 to touch the dry powder fire extinguisher 9 to open the air inlet 10, which is easy to use and convenient to take the inflation head 66 for inflation and pressurization. A ventilation pipe is laid inside the extension rod 64 to connect the inflation head 66 with the booster pump 62. This design helps to transmit the pressurized gas generated by the booster pump 62.

[0021] As a second embodiment of the utility model: when the dry powder fire extinguisher 9 is pressurized, firstly, a plurality of dry powder fire extinguishers 9 are placed in the discharge slot 7 on the drum 4. With the help of the rotation of the movable rod 8, the dry powder fire extinguisher 9 is pushed forward. During the forward pushing process, the first dry powder fire extinguisher 9 comes out from the left side of the drum 4 and enters the placement rack 32. Due to the gravity of the dry powder fire extinguisher 9, the pressure sensing switch 33 at the bottom of the placement rack 32 starts the lifting motor 2, so that the lifting motor 2 and the connected fixing ring 61 will slide downward along the fixing column 1. When the fixing ring 61 reaches the bottom of the lifting slot 63, the extension rod 6 is just extended. 4 squeezes the top of the dry powder fire extinguisher 9. Through the squeezing of the pressing plate 65, the air inlet 10 on the dry powder fire extinguisher 9 will open. At this time, the staff will align the inflation head 66 placed on the pressing plate 65 with the air inlet 10, and the pressurized gas generated by the booster pump 62 enters the air inlet 10 to complete the pressurization of the dry powder fire extinguisher 9. Then, after the pressurized dry powder fire extinguisher 9 is taken away, the gravity squeezing is lost, the pressure sensing switch 33 is reset, and the lifting motor 2 drives the fixed sleeve 61 to lift and restore upward. Similarly, when the next dry powder fire extinguisher 9 enters the placement rack 32, the lifting motor 2 is affected by the pressure sensing switch and continues to descend for pressurization.
