A filling head 41 is installed on the bottom wall of the filling valve 4. A placement seat 5 is fixedly connected to the upper outer wall of the base 1 by a support rod. The placement seat 5 is provided with three sliding grooves 51. A slider 52 is slidably arranged in the sliding grooves 51. A positioning rod 53 is fixedly connected to the upper outer wall of the slider 52. Under the action of the driving mechanism 7, the three positioning rods 53 can be made to approach the fire extinguisher bottle simultaneously and clamp and fix it to ensure the stability during filling. A leak-proof mechanism 6 is also provided on the bottom wall of the filling valve 4. A driving mechanism 7 is also provided on the upper outer wall of the base 1.
[0025] Specifically, such as Figure 2 and Figure 3 As shown, a filling device for fire extinguishing agent production includes a leak-proof mechanism 6 comprising a receiving ring 61, an abutment ring 62, an air bladder 63, a spring 64, a bidirectional air pump 65, and an air pipe 66. The receiving ring 61 is fixedly connected to the bottom wall of the filling valve 4. The abutment ring 62 slides within the receiving ring 61. An air bladder 63 is mounted on the inner wall of the abutment ring 62. A spring 64 abuts against the upper inner wall of the abutment ring 62. A bidirectional air pump 65 is installed on the upper outer wall of the L-shaped support plate 2. The bidirectional air pump 65 and the air bladder 63 are connected via the air pipe 66. The filling valve 4 is... When cylinder 3 is pushed down, the contact ring 62 can press against the mouth of the fire extinguisher, and the mouth of the fire extinguisher is fitted into the contact ring 62. The spring 64 provides a certain amount of tolerance space between the contact ring 62 and the receiving ring 61, which can be used for mouths of different heights. After the contact ring 62 is fitted into the mouth of the fire extinguisher, the bidirectional air pump 65 can inflate the air bag 63 through the air pipe 66, which will wrap around the mouth of the fire extinguisher and form a seal. During the filling process, the dry powder will not leak through the gap between the mouth of the fire extinguisher and the filling head 41, thus avoiding pollution of the working environment.
[0026] Specifically, such as Figure 4 and Figure 5As shown, a filling device for producing fire extinguishing agent includes a drive mechanism 7 comprising a motor 71, a frustum 72, limiting seats 73, arc-shaped grooves 74, a moving column 75, a drive frame 76, and an L-shaped connecting rod 77.

An L-shaped connecting rod 77 is fixedly connected to the side wall of the frame 76 away from the truncated cone 72. The other end of the L-shaped connecting rod 77 is fixed to the slider 52. The output shaft of the motor 71 can drive the truncated cone 72 to rotate. When the truncated cone 72 rotates, under the limit of the limit seat 73, the moving column 75 pulls the frame 76 to move towards the center of the truncated cone 72. Under the drive of the L-shaped connecting rod 77, the slider 52 drives the positioning rod 53 to move closer to the fire extinguisher bottle, so that the three positioning rods 53 clamp and fix the fire extinguisher bottle.

The telescopic end of cylinder 3 pushes the filling valve 4 and filling head 41 downward, so that the filling head 41 is inserted into the fire extinguisher bottle. The contact ring 62 will abut against the mouth of the fire extinguisher bottle. The bidirectional air pump 65 inflates the air bag 63 through the air pipe 66, so that the air bag 63 expands and wraps around the mouth of the fire extinguisher bottle to form a seal. During the filling process, the dry powder will not leak through the gap between the mouth of the fire extinguisher bottle and the filling head 41, thus avoiding pollution of the working environment.
