When the limiting column 244 touches the other of the first baffle 213 and the second baffle 214, the block portion 242 is in a non-interference fit unlocking state relative to the lock portion 31, so that the locked state and the unlocked state can be perceived when the internal structure is not visible, which is convenient for disassembly and assembly.

[0032] See also Figure 6 , Figure 6 This is a cross-sectional view of an embodiment of a ventilation component of the present application.

[0033] The air inhalation body 21 is provided with an air inhalation channel 41, a fluid channel 42, an inner pipe 43 and a gas release chamber 44, wherein the air inhalation channel 41 passes through the inner and outer sides of the air inhalation body 21 for gas delivery, the fluid channel 42 is connected to the air inhalation channel 41, the inner pipe 43 is connected to the fluid channel 42, the gas release chamber 44 is arranged on the outer periphery of the inner pipe 43, the inner pipe 43 is provided with an open end on the inner side of the air inhalation body 21, the gas release chamber 44 is connected to the concave cavity 25, and the concave cavity 25 is connected to the outside.

[0034] Specifically, when the safety valve 46 is against the open end of the inner pipe 43, the gas in the air intake channel 41 cannot enter the air release chamber 44. When the safety valve 46 is pushed open by the gas, the gas enters the air release chamber 44 from the inner pipe 43, and is discharged from the air intake body 21 through the concave cavity 25.

[0035] Among them, the locking member 24 can be suspended and penetrate the air suction body 21, the wheel part 243 is accommodated in the concave cavity 25, and there is a gap 47 between the locking member 24 and the air suction body 21. The gap 47 can be connected to the air leakage chamber 44. Therefore, the air leakage chamber 44 can be connected to the concave cavity 25 through the gap 47, and the gas can be discharged through the gap 47 and the concave cavity 25. The gap 47 and the concave cavity 25 can simultaneously play the role of exhausting and installing the locking member 24, which is multi-functional, simplifies the gas path design, and saves costs.

[0036] Among them, the intake body 21 may also include: a detection channel 48, a baffle 49 and an oxygen sensor 50. The detection channel 48 is connected to the intake channel 41. The detection channel 48 is provided with a thread for connecting the oxygen sensor 50, which is used to screw the oxygen sensor 50 to the detection channel 48, so that the detection probe of the oxygen sensor 50 is in the detection channel 48. The baffle 49 extends from the intake channel 41 and points to the detection channel 48. The baffle 49 is used to guide part of the gas to the detection channel 48 when the gas flows from the inside of the intake channel 41 to the outside of the intake channel 41. When the gas diffuses to the detection channel 48, the detection probe of the oxygen sensor 50 can be used to detect and feedback indicators such as the oxygen concentration of the gas, which is convenient for rapid gas detection and timely feedback of the current gas oxygen concentration.

[0037] In one embodiment, the air intake body 21 is further provided with a mounting seat 51 on the outer periphery of the detection channel 48, and the mounting seat 51 is used to accommodate and assemble the oxygen sensor 50, so that the oxygen sensor 50 can be assembled to the air intake body 21 through the mounting seat 51. Among them, the detection channel 48 is provided with a thread matching the oxygen sensor 50 at the position connected to the mounting seat 51, so that the sensing end of the oxygen sensor 50 is installed in the detection channel 48 through the thread, and the main body of the oxygen sensor 50 is accommodated in the mounting seat 51.

[0038] In this embodiment, when the air intake body 21 is delivering gas, at the position of the baffle 49, the gas is partially guided to the detection channel 48, and the oxygen sensor 50 installed in the detection channel 48 quickly measures indicators such as oxygen concentration and makes corresponding feedback, which is convenient for the user to adjust according to the feedback results, greatly reducing the time required for oxygen concentration measurement, effectively improving the speed of oxygen concentration measurement, and having a simple structure and easy implementation.
