The embodiment of the invention discloses a gas inlet mechanism and a negative pressure system. The gas inlet mechanism comprises a first gas inlet end, a first gas outlet end and a first channel located between the first gas inlet end and the first gas outlet end, a first gas driving unit is arranged on the first channel, a first filtering assembly is arranged between the first gas inlet end andthe first gas driving unit, and a second filtering assembly is arranged between the first gas outlet end and the first gas driving unit. According to the gas inlet mechanism, the first filtering assembly is arranged between the first gas inlet end and the first gas driving unit, and the second filtering assembly is arranged between the first gas outlet end and the first gas driving unit, so that the cleanliness of gas passing through the gas inlet mechanism is guaranteed, and further deterioration of the quality of the gas in a cavity supplied with the gas through the gas inlet mechanism is avoided.
Description
technical field [0001] The invention relates to the technical field of protection, in particular to an air intake mechanism and a negative pressure system. Background technique [0002] Hazardous substances are often transmitted through the air. In order to prevent their spread, the harmful substances are generally isolated from the outside world by means of isolation. The traditional negative pressure system prevents the leakage of harmful substances by forming negative pressure. Since the air intake mechanism supplying air to the negative pressure system lacks a filtering function, the cleanliness of the intake air cannot be guaranteed. Therefore, there is a risk of further deterioration of the gas quality inside the negative pressure system. Contents of the invention [0003] The purpose of the present invention is to provide a negative pressure system when preventing harmful substances from diffusing with the air, so as to solve the technical problem that the traditio...
