[0045] Among them, the box body 21 has a cavity 210, a first opening connected to the cavity 210, and a cylinder valve interface 253 connected to the cavity 210; the cabinet door 22 is connected to the box body 21 to selectively open or close the first opening; the pipeline 23 is located in the accommodating cavity and installed on the inner wall of the box body 21, and the pipeline 23 includes a main pipe 231 and a plurality of branch pipes 233. One end of the main pipe 231 is provided with a cylinder connector 232 for connecting the cylinder 10, and the other end is connected to a plurality of branch pipes 233, and each branch pipe 233 is provided with a valve; the exhaust connector 239 is arranged in the box body 21 and connected to the cavity 210, and the exhaust connector 239 is provided with an exhaust valve (not shown); the fire-fighting mechanism is arranged on the top of the box body 21.

[0046] Among them, when the steel cylinder 10 is connected to the integrated exhaust box 20, the valve of the steel cylinder 10 is located outside the cavity 210, so that the valve of the steel cylinder 10 can be opened or closed according to actual needs. The interface part of the steel cylinder 10 is tightly inserted into the cavity 210 through the cylinder valve interface 253, and the interface part is detachably connected to the cylinder connector 232 arranged on the pipeline 23, so as to realize the connection between the gas channel and the pipeline 23, and then the steel cylinder 10 can be used to transport gas into the pipeline 23, and the detachable connection between the interface part and the cylinder connector 232 also facilitates the replacement of the steel cylinder 10 according to actual needs.

[0047] It should be noted that the detachable method here includes but is not limited to snap-on connection, threaded connection, etc., which can be set with reference to relevant technologies and will not be described in detail here. In order to avoid accidental disassembly of the interface part and the cylinder connector 232, an anti-accidental disassembly mechanism can also be set at the connection between the two. The specific anti-accidental disassembly mechanism can be referred to relevant technologies and will not be limited here.

[0048] The present application adopts the setting of multiple branch pipes 233, which can meet various functions such as transporting gas to the outside, purging or vacuuming the pipeline 23 according to actual needs, and each branch pipe 233 is provided with a valve, and the corresponding valve can be opened and closed according to actual needs to avoid interference between the multiple branch pipes 233.

[0049] Since the pipe 23 is located in the accommodating cavity and installed on the inner wall of the box body 21, and the connection between the interface of the cylinder 10 and the main pipe 231 is located in the cavity 210, that is, the pipeline from the interface of the cylinder 10 to the cylinder interface is completely located in the box body 21, the risk of leakage can be effectively alleviated or avoided, and through the setting of the exhaust joint 239, the cavity 210 can be ventilated and purged by an external exhaust mechanism according to actual needs (the cabinet door 22 can be opened according to actual needs during the ventilation process), thereby improving the safety in the cavity 210.

[0050] That is, the integrated exhaust box 20 shown in the present application is equivalent to integrating the existing exhaust hood and the purge box into one, which not only alleviates or avoids the risk of leakage in the pipeline from the interface of the cylinder 10 to the cylinder interface, but also only requires one set of fire-fighting mechanism to meet fire-fighting needs, effectively reducing production costs.

[0053] Therefore, if Figure 1 As shown, the fire fighting agency also includes a negative pressure gauge 242 , which has a probe that penetrates into the box body 21 for detecting the air pressure in the cavity 210 , and a display screen that is located outside the box body 21 and displays the air pressure in the cavity 210 .

[0054] The negative pressure gauge 242 is used to test the exhaust condition in the integrated exhaust box 20 of the equipment. Through the above setting, the negative pressure in the cavity 210 can be obtained intuitively, so that the operator can perform relevant operations in time according to the negative pressure in the cavity 210, such as closing the exhaust valve or opening the cabinet door 22, etc., to improve the safety performance of the integrated exhaust box 20.

[0055] In order to facilitate the operator to carry out relevant processing in a timely manner, the box 21 may be provided with an alarm mechanism, which is connected to the negative pressure gauge 242 by signal or electrical connection, so as to alarm when the air pressure in the cavity 210 obtained by the negative pressure gauge 242 reaches a preset value. The alarm mechanism includes but is not limited to a speaker, a buzzer and / or an indicator light.

[0056] For ease of operation, the negative pressure gauge 242 is opened on the side of the box body 21 where the first opening is provided.

[0059] Among them, the first branch pipe is provided with an output connector 235, which is used to connect to an external gas pipe to output gas to the outside; the second branch pipe is provided with a vacuum connector 236, which is used to connect to an external vacuum mechanism; the third branch pipe is provided with an air supply pipe connector 238, which is used to connect to an external air supply mechanism to supply air into the pipeline 23.

[0060] By setting the above three branch pipes 233 , not only can the pipeline 23 be used to output the gas in the cylinder 10 to the outside, but also vacuuming and purging operations can be performed in the pipeline 23 respectively, thereby improving the safety of the pipeline 23 .

[0061] The number of the output connector 235 , the vacuum connector 236 , and the air supply pipe connector 238 can be one or more, respectively, and can be set according to actual needs.

[0062] See also Figure 2 , Figure 3 as well as Figure 4 The box body 21 has a fixing plate 211 on one side away from the first opening, the pipe 23 is installed on the fixing plate 211, and the fixing plate 211 has a second opening;

[0067] Through the detachable setting mode, the mounting plate 252 with cylinder valve interfaces 253 of different sizes can be selected according to the sizes of different cylinders 10, so that it has universal applicability.

[0068] It can be understood that in order to facilitate the tight installation of the outlet part of the cylinder 10 on the cylinder valve interface 253, the mounting plate 252 can be obtained by docking and locking two mounting plate 252 units, wherein each mounting plate 252 unit is provided with an arc-shaped notch, and after the two mounting plate 252 units are docked, the two arc-shaped notches form the cylinder valve interface 253.

[0069] The integrated exhaust box 20 further includes a support frame 26 for supporting the box body 21 .

[0070] The height of the support frame 26 may be fixed or adjustable.
