As shown in fig. 1 to 3, an air path inlet mechanism provided by an embodiment of the present utility model includes an air inlet connector 1, an air outlet connector 2, a filter 3, a one-way valve 4, a flow-dispersing disc 5 provided with a plurality of flow-guiding through holes 51, and a mounting block 6 provided with an air path 61, wherein the air inlet connector 1 is inserted into an inlet of the air path 61, and the air outlet connector 2 is inserted into an outlet of the air path 61; it is to be understood that the air inlet joint 1 and the air outlet joint 2 are mounted at opposite ends of the mounting block 6, and the flow-guiding plate 5 is fully distributed with the circular flow-guiding through holes 51.
The filter 3 is arranged in an air inlet hole of the air inlet joint 1, the flow-dispersing disc 5 is arranged in the air passage 61, and the air inlet hole is communicated with the air passage 61 through the flow-guiding through hole 51; the check valve 4 is installed in the gas passage 61 and is used to control the flow direction of the gas in the gas passage 61. It will be appreciated that the inlet end of the non-return valve 4 is directed towards the inlet fitting 1 and the outlet end of the non-return valve 4 is directed towards the outlet fitting 2, so that gas in the inlet fitting 1 may flow through the non-return valve 4 towards the outlet fitting 2, whereas gas in the outlet fitting 2 may not flow through the non-return valve 4 towards the inlet fitting 1, i.e. the non-return valve 4 ensures a unidirectional flow of gas in the gas channel 61.
In the utility model, the air inlet connector 1 is inserted into the inlet of the air passage 61, the air outlet connector 2 is inserted into the outlet of the air passage 61, the flow-dispersing disc 5 is arranged in the air passage 61, and the air inlet hole is communicated with the air passage 61 through the flow-guiding through hole 51; when the turbulent flow phenomenon exists in the gas input into the gas outlet connector 2 by the gas inlet connector 1, the turbulent flow gas is converted into laminar flow gas through the flow guiding through holes 51 of the flow guiding disc 5, so that the stability of the gas input into the breathing equipment is ensured. In addition, the filter 3 ensures cleanliness of the gas entering the gas passage 61, and the one-way valve 4 ensures one-way flow of the gas passage 61. In addition, the air channel inlet mechanism has simple structure and low manufacturing cost.
In one embodiment, as shown in fig. 4 and 5, the check valve 4 includes an elastic member 41, a piston 42, and a valve cylinder 43 with a through hole 431, where the piston 42 includes a plug body 421 with a through hole 431, and a plurality of support arms 422, and the plurality of support arms 422 are connected to the plug body 421 at annular intervals; the piston 42 is mounted in the through hole 431 through the elastic member 41, one end of the support arm 422 away from the plug 421 is abutted against the inner wall of the through hole 431, and a flow passage space is formed between two adjacent support arms 422; the plug body 421 is used to block or conduct the inlet of the valve cylinder 43. It will be appreciated that the resilient member 41 includes, but is not limited to, a spring or the like; the opening inner diameter of the inlet of the valve cylinder 43 is smaller than the inner diameter of the through hole 431.
Specifically, when the high-pressure gas is input into the air outlet connector 2 through the air inlet connector 1, the high-pressure gas drives the piston 42 to move toward one end of the air outlet connector 2, the elastic member 41 is compressed by the piston 42, the plug body 421 opens the opening of the valve cylinder 43, so that the gas flows into the through hole 431 through the flow passage space, flows into the air passage 61 through the through hole 431, and finally flows out of the air outlet connector 2. If the air outlet connector 2 flows to the air inlet connector 1 through the air passage 61, the air in the through hole 431 cannot drive the piston 42 to move, and the plug body 421 is in a state of blocking the inlet of the valve cylinder 43, so that the air in the air passage 61 cannot flow into the air inlet connector 1.

Preferably, the plug 421, the support arm 422, and the ring seal 44 are integrally formed as a structural member. When the piston 42 is in the state of blocking the inlet of the valve cylinder 43 due to the elastic force of the elastic member 41, the annular sealing ring 44 is inserted into the annular groove, so that the sealing performance of the piston 42 for blocking the inlet of the valve cylinder 43 is ensured.
In one embodiment, as shown in fig. 1, the mounting block 6 is further provided with a first channel communicated with the air channel 61, and the air channel inlet mechanism further comprises a safety valve 7 inserted in the first channel. It will be appreciated that when the pressure of the gas in the gas passage 61 is greater than the preset relief pressure of the relief valve 7, the relief valve 7 will open, so that the gas in the gas passage 61 leaks into the external environment through the first passage and the relief valve 7, thereby ensuring the safety of the gas passage inlet mechanism.
In an embodiment, as shown in fig. 1, the mounting block 6 is further provided with a second channel communicated with the air channel 61, and the air channel inlet mechanism further comprises a pressure reducing valve 8 inserted in the second channel.
