It is worth noting that in actual use, the staff can set the multiple filling heads 14 to different sizes according to the use requirements, thereby ensuring that different types of heptafluoropropane fire extinguishers can be adapted.

[0026] A filling component 2 is slidably connected to the mounting seat 1, and an electric push rod 15 is arranged on the mounting seat 1. The push rod end of the electric push rod 15 is fixedly connected with a sealing component 3, and the sealing component 3 is sleeved on the filling component 2; by providing the sealing component 3, the filling component 2 can effectively achieve a sealing effect on the connecting component 4 after being connected during use, thereby increasing the sealing after the connection.

[0027] In order to achieve the effect of quickly replacing the filling head 14, a filling tube 21 is provided on the filling assembly 2 in this embodiment. The filling tube 21 is slidably connected to the transmission motor 11, and one end of the filling tube 21 is fixedly connected to the limiting platform 22. A connecting port 23 is provided on the left side of the limiting platform 22, and a connecting spring 24 is provided on the right side of the limiting platform 22. The connecting spring 24 is fixedly connected to the mounting seat 1, and the other end of the filling tube 21 is fixedly connected to a connecting head 25, and a sealing plate 26 and a sealing platform 27 are provided on the connecting head 25.

[0028] As a preferred technical solution in this embodiment, when the filling head 14 needs to be replaced, the staff can first control the electric push rod 15 to drive the sealing component 3 to produce a displacement effect. During the displacement of the sealing component 3, it will be separated from the connecting component 4, and then it can drive the filling tube 21 to produce a displacement, thereby realizing the separation between the connecting head 25 and the connecting component 4. Then the work can be carried out by controlling the transmission motor 11 to drive the transmission rod 12 to rotate. During the rotation of the transmission rod 12, it can drive the mounting table 13 to rotate, and then the mounting table 13 can drive the connecting component 4 to rotate. When a filling head 14 that meets the use requirements is moved to the filling component 2, the staff can control the electric push rod 15 to drive the sealing component 3 to produce a displacement effect. During the displacement of the sealing component 3, it can be fitted with the connecting component 4. After it is fitted with the connecting component 4, the filling tube 21 will be driven by the connecting spring 24 to insert the connecting head 25 and the sealing plate 26 into the connecting component 4, thereby realizing the replacement effect of the filling head 14.

[0029] Embodiment 2:

[0030] See also Figure 3-5 In order to achieve the sealing effect between the filling component 2 and the filling head 14, a connecting sleeve 41 is provided on the connecting component 4 in this embodiment. The connecting sleeve 41 is fixedly connected to the mounting platform 13. A docking platform 42 is provided on the left side of the connecting sleeve 41. A docking port 43 is provided in the docking platform 42. The connecting sleeve 41 is connected to the filling head 14. An infrared lamp 44 is provided on the connecting sleeve 41. By providing the docking platform 42 and the docking port 43, when the connecting head 25 is inserted into the docking port 43, the sealing plate 26 is plugged into the docking port 43, and the sealing platform 27 is plugged into the docking platform 42, thereby ensuring that it has good sealing after the connection.

[0031] In order to ensure the tightness and accuracy of the docking between the filling component 2 and the connecting component 4, the sealing component 3 in this embodiment is provided with a mounting sleeve 31, which is sleeved on the outside of the filling tube 21, and the left end of the mounting sleeve 31 is fixedly connected to a connecting plate 34, and the left side of the connecting plate 34 is fixedly connected to a supporting spring 35, and the other end of the supporting spring 35 is fixedly connected to the mounting seat 1.

A limiting ring 36 is provided in the sealing sleeve 33, and a sealing ring 37 is provided on the sealing sleeve 33. An infrared sensor 38 is provided on the connecting platform 32.

[0032] As a preferred technical solution in this example, in actual use, when the staff controls the transmission motor 11 to drive the transmission rod 12 and the mounting platform 13 to rotate, it will drive the connecting sleeve 41 and the infrared lamp 44 to rotate. When the infrared lamp 44 rotates to be in a straight line with the infrared sensor 38, the infrared sensor 38 will receive the light signal of the infrared lamp 44 and control the transmission motor 11 to stop. At this time, the filling tube 21 and the docking port 43 are in the same straight line. Then the electric push rod 15 can be controlled so that the push rod drives the connecting platform 32 to produce a displacement effect. During the displacement of the connecting platform 32, it can be sleeved on the outside of the docking platform 42. At the same time, the filling tube 21 located inside the mounting sleeve 31, under the action of the connecting spring 24, enables the sealing plate 26 to be inserted into the docking port 43, and the sealing platform 27 to be inserted into the docking platform 42. At the same time, the sealing ring 37 can keep in contact with the connecting sleeve 41, and a good sealing effect is formed at this time.

[0033] As a preferred technical solution in this embodiment, when the staff controls

[0034] The working principle of the above embodiment is:

[0035] 1. When it is necessary to replace the filling head 14, the staff can first control the electric push rod 15 to drive the sealing component 3 to produce a displacement effect. During the displacement of the sealing component 3, it will be separated from the connecting component 4, and then the filling tube 21 can be driven to be displaced, thereby realizing the separation between the connecting head 25 and the connecting component 4. Then, the work can be carried out by controlling the transmission motor 11 to drive the transmission rod 12 to rotate. During the rotation of the transmission rod 12, the mounting table 13 can be driven to rotate, and then the mounting table 13 can drive the connecting component 4 to rotate. When a filling head 14 that meets the use requirements is displaced to the filling component 2, the staff can control the electric push rod 15 to drive the sealing component 3 to produce a displacement. During the displacement of the sealing component 3, it can be fitted with the connecting component 4. After it is fitted with the connecting component 4, the filling tube 21 will be driven by the connecting spring 24 to insert the connecting head 25 and the sealing plate 26 into the connecting component 4, thereby realizing the replacement effect of the filling head 14.

[0036] 2. When the staff controls the transmission motor 11 to drive the transmission rod 12 and the mounting platform 13 to rotate, the connection sleeve 41 and the infrared lamp 44 will be driven to rotate. When the infrared lamp 44 rotates to be in a straight line with the infrared sensor 38, the infrared sensor 38 will receive the light signal of the infrared lamp 44 and control the transmission motor 11 to stop. At this time, the filling tube 21 and the docking port 43 are in the same straight line, and then the electric push rod 15 can be controlled to drive the connection platform 32 to produce a displacement effect. During the displacement of the connection platform 32, it can be sleeved on the outside of the docking platform 42. At the same time, the filling tube 21 located inside the mounting sleeve 31 is inserted into the docking port 43 under the action of the connecting spring 24, and the sealing plate 26 is inserted into the docking port 43, and the sealing platform 27 is inserted into the docking platform 42.
