[0026] An opening is arranged at the top of the filling box body 1, and a discharge port 5 for outputting explosion-proof balls is arranged at the bottom of the filling box body 1. The explosion-proof balls are put into the filling box body 1 from the top and output into the oil tank through the discharge port 5.

One end of the elastic component 4 is fixedly arranged on the filling box body 1 and the other end is fixedly connected to the movable arm 3. An elastic force is applied to the movable arm 3 by the arranged elastic component 4, and the elastic component 4 generates a pulling force to drive the movable arm 3 so that the movable baffle 2 closes the opening of the filling box body 1 part, so as to improve the sealing performance of the filling box body 1, thereby reducing the gas blown into the air pressure component and discharged from the top opening of the filling box body 1, further improving the filling efficiency of the explosion-proof balls, and the user can add explosion-proof balls by applying pressure to open the movable baffle 2.
[0027] Preferably, a guide inclined plate 6 is provided on the opposite side of the movable baffle 2, and the guide inclined plate 6 is obliquely arranged in the filling box 1, and the height of the side of the guide inclined plate 6 close to the movable baffle 2 is lower than the height of the side away from the movable baffle 2, the movable baffle 2 is inclined, and the height of the side close to the guide inclined plate 6 is lower than the height of the side away from the guide inclined plate 6, and the hinge position of the movable baffle 2 and the filling box 1 is at a position on the upper side of the movable baffle 2, such as Figure 4As shown, the cross-section of the movable baffle 2 and the guide inclined plate 6 is V-shaped, and the upper part of the movable baffle 2 and the guide inclined plate 6 in the filling box 1 is the preparation cavity 11, and the lower part of the movable baffle 2 and the movable guide inclined plate 6 in the filling box 1 is the filling cavity 12. When in use, the staff puts the explosion-proof ball into the preparation cavity 11, and opens the guide inclined plate 6 by applying pressure to make the explosion-proof ball in the preparation cavity 11 slide along the guide inclined plate 6 into the filling cavity 12.
[0028] Preferably, a control handle 31 is provided on the movable arm 3, and the control handle 31 is located on the side away from the movable baffle 2, so that a labor-saving lever can be formed. The set control handle 31 can facilitate the user to unfold the movable baffle 2 without contacting the movable baffle 2, thereby improving the filling efficiency of the explosion-proof ball.
[0029] It can be selected that the elastic component 4 in the present solution has a certain elasticity and can tighten the movable arm 3 through elasticity. Therefore, the elastic component 4 in the present solution can be a tension spring, a torsion spring, a spring sheet, an elastic rope, a rubber band, etc., wherein in combination with the use scenario of the present solution and the stability of the elastic component 4, it is preferably set as a tension spring, one end of the tension spring is fixed on the side wall of the filling box 1, or a corresponding hook is set on the side wall of the filling box 1, which is connected to the tension spring through the hook, and the other end of the tension spring is connected to the movable arm 3, and the movable arm 3 is tightened by the tension spring to relatively close the filling box 1.
[0030] Preferably, the air pressure component includes an air port 7, which is arranged in the filling box 1, and the output direction of the air port 7 is arranged toward the discharge port 5. Gas is input into the filling box 1 through the arranged air port, so that the explosion-proof balls inside the filling box 1 keep moving under the disturbance of the gas and cannot block the discharge port 5, thereby promoting the filling of the explosion-proof balls, and at the same time generating a downward blowing force to further push the explosion-proof balls into the discharge port 5.
[0031] Preferably, the end of the filling box 1 is arranged in a bucket shape, and the discharge port 5 is arranged at the lowermost position of the filling box 1. The bucket-shaped structure can guide the explosion-proof balls and improve the filling efficiency of the explosion-proof balls.

At the same time, the staff pushes the control handle 31 back and forth to make the explosion-proof ball in the preparation chamber 11 continue to enter the filling chamber 12.
