[0026] As Figures 1 to 4 shown, an industrial gas filling device for gas detection and early warning includes a housing 1. An alarm 2 is provided on the housing 1. An air inlet and an air outlet are respectively opened on the front and rear sides of the housing 1. A fixing block 4 is arranged inside the air inlet of the housing 1. A gas distribution mechanism 5 is installed on the front surface of the fixing block 4. A protection mechanism 6 is arranged on one side of the housing 1 close to the gas distribution mechanism 5. Specifically, by starting the gas distribution mechanism 5, the gas around the housing 1 is quickly guided into the housing 1, so that the subsequent housing 1 can quickly detect the surrounding gas. The position of the driving mechanism of the gas distribution mechanism 5 is arranged inside the housing 1. Moreover, during the use of the housing 1, it has the function of isolating high temperature, so that the driving mechanism of the subsequent gas distribution mechanism 5 is not easily damaged by high temperature during long-term startup, thereby minimizing the situation that the device cannot be used normally in a high-temperature environment, and thus improving the practicability of the device.

[0027] As Figures 1 to 4As shown, the valve mechanism 5 includes a gear 1 501, a rotating rod 504 and a motor 506. A through hole is provided on the front of the fixed block 4, and the rotating rod 504 is rotatably connected inside the through hole of the fixed block 4. The gear 1 501 is installed on the outer surface of the rotating rod 504, and a fan blade 505 is provided on the front of the rotating rod 504. The external teeth of the gear 1 501 are meshed and connected with the gear 2 502, and the inner wall of the gear 2 502 is provided with a connecting rod 503. The motor 506 is installed on the front inner wall of the outer shell 1, and a through hole is provided on the front of the outer shell 1. The output shaft of the motor 506 passes through the inner through hole of the outer shell 1 and is installed on the back of the connecting rod 503.

[0028] Specifically, the starting motor 506 drives the gear 2 502 and the gear 1 501 to trigger the fan blade 505 to rotate, so that the fan blade 505 quickly guides the surrounding gas of the outer shell 1 to the inside of the outer shell 1 during the rotation, so that the outer shell 1 can quickly detect the surrounding gas subsequently; the motor 506 is set inside the outer shell 1, and the outer shell 1 has the function of isolating high temperature during use, so that the motor 506 of the subsequent valve mechanism 5 is not easy to be damaged by high temperature during the long-term startup process, thereby trying to avoid the subsequent device from being unable to be used normally in a high temperature environment, thereby improving the practicality of the device; the motor 506 is installed inside the outer shell 1, so that the subsequent motor 506 can be disassembled, and then the subsequent fan blades 505 or motor 506 can be disassembled and replaced when damaged, thereby reducing the replacement and maintenance costs of the subsequent valve mechanism 5 when damaged.

[0030] like Figure 1 and Figure 2As shown, a connecting pipe 3 is installed inside the air outlet of the outer shell 1, a positioning hole is provided on the right side of the outer shell 1, the exhaust end of the connecting pipe 3 is installed inside the positioning hole of the outer shell 1, and an exhaust hole is provided on the left side of the outer shell 1. The positions of the exhaust hole and the positioning hole inside the outer shell 1 are both kept parallel to the motor 506; specifically, when the internal gas of the subsequent outer shell 1 is discharged, the air inlet end of the connecting pipe 3 is installed inside the air outlet of the outer shell 1, so that the subsequent connecting pipe 3 guides the gas discharged from the outer shell 1 to one side of the motor 506, and then guides the gas guided to one side of the motor 506 out of the inner part of the outer shell 1 through the exhaust hole of the outer shell 1, so that the air in the space where the subsequent motor 506 is located can circulate quickly, and then the subsequent motor 506 can dissipate heat in the sealed space inside the outer shell 1, thereby minimizing damage to the subsequent motor 506 during use.

[0031] like Figure 1 and Figure 2 As shown, the protective mechanism 6 includes a fixed circular ring 601, which is installed on the front of the outer shell 1, and the inner wall of the fixed circular ring 601 is provided with a fixed circular ring 602, and the inner wall of the fixed circular ring 601 is clamped with a circular frame 603, the back of the circular frame 603 is abutted against the front of the fixed circular ring 602, and the inner wall of the circular frame 603 is provided with a filter 604, and the position of the filter 604 is set on the suction path of the fan blade 505; specifically, by setting the positions of the fixed circular ring 601 and the filter 604 at the outer end of the fan blade 505, the subsequent protective mechanism 6 blocks the rotating rod 504, thereby avoiding the rear The subsequent staff will come into contact with the rotating rotating rod 504 during the operation, thereby improving the safety of the subsequent rotating rod 504 during use; the filter screen 604 is set on the air intake path of the fan blade 505, so that the subsequent filter screen 604 can filter the dust guided by the rotating rod 504 to the inside of the outer shell 1, thereby avoiding as much as possible that the subsequent valve mechanism 5 will suck dust into the interior of the outer shell 1 during the opening process, and preventing the external teeth of the subsequent gear 1 501 and gear 2 502 from being stuck with debris during use, thereby reducing the number of times that the subsequent staff regularly cleans the valve mechanism 5 and the inside of the outer shell 1.

[0032] At the same time, the circular frame 603 is clamped inside the fixed circular ring 601, and the position of the fixed circular ring 601 is set at the outer end of the outer shell 1, so that the circular frame 603 can be quickly disassembled during use, thereby reducing the time and labor spent by subsequent staff on cleaning the filter 604.

[0033] like Figure 1 and Figure 2As shown, a slot is provided on the front of the fixed circular ring 602, and a contact switch 7 is arranged inside the slot of the fixed circular ring 602. The front of the contact switch 7 is attached to the back of the circular frame 603, and the contact switch 7 is electrically connected to the control end of the alarm 2. Specifically, the back of the circular frame 603 is abutted against the front of the contact switch 7, so that when the circular frame 603 is loosened and falls from the fixed circular ring 1 601, the contact switch 7 is triggered to start the alarm 2 to sound an alarm, so that the subsequent staff can promptly check the detachment of the circular frame 603 when walking around the device, thereby improving the protection performance of the subsequent protection mechanism 6 during use.

[0034] In summary: by starting the motor 506 to drive the gear 2 502 and the gear 1 501 to trigger the fan blade 505 to rotate, the fan blade 505 can quickly guide the gas around the outer shell 1 to the inside of the outer shell 1 during the rotation, so that the outer shell 1 can quickly detect the surrounding gas subsequently; the air inlet end of the connecting pipe 3 is installed inside the air outlet of the outer shell 1, so that the subsequent connecting pipe 3 guides the gas discharged from the outer shell 1 to one side of the motor 506, and then guides the gas guided to one side of the motor 506 out of the inner part of the outer shell 1 through the exhaust hole of the outer shell 1, so that the air in the space where the subsequent motor 506 is located can circulate quickly, and then the subsequent motor 506 can dissipate heat in the sealed space inside the outer shell 1, thereby minimizing damage to the subsequent motor 506 during use.

[0035] At the same time, by setting the positions of the fixed ring 1 601 and the filter 604 at the outer end of the fan blade 505, the subsequent protection mechanism 6 blocks the rotating rod 504, thereby avoiding as much as possible the subsequent staff from coming into contact with the rotating rotating rod 504 during the work; by setting the position of the filter 604 on the suction path of the fan blade 505, the subsequent filter 604 filters the dust guided by the rotating rod 504 to the inside of the outer shell 1, thereby avoiding as much as possible the subsequent gas distribution mechanism 5 from sucking dust into the inside of the outer shell 1 during the opening process, and preventing the subsequent gear 1 501 and gear 2 502 from getting stuck with debris on the external teeth during use; by the back of the circular frame 603 abutting against the front of the contact switch 7, when the subsequent circular frame 603 loosens and falls from the fixed ring 1 601, the contact switch 7 is triggered to start the alarm 2 to sound an alarm, so that the subsequent staff can timely check the falling off of the circular frame 603 when walking around the device, thereby improving the protectiveness of the subsequent protection mechanism 6 during use.
