Embodiment 1

[0043] like Figure 1-2 As shown, the novel respiratory purification device provided by this embodiment comprises an air induction device, a soaking device, a centrifugal device and an air duct; the outlet of the air induction device communicates with the inlet of the air duct, the centrifugal device is arranged in the air duct, and the soaking device It is arranged between the air-inducing device and the centrifugal device, and the outlet of the ventilation pipe is connected with the inner cavity of the mask; the air sent from the outlet of the air-inducing device passes through the soaking device and the centrifugal device in turn, and flows to the inner cavity of the mask through the ventilation pipe; Wetting device comprises Venturi tube 20 and water tank 40, and Venturi tube 20 communicates with water tank 40 through water suction pipe 50, and Venturi tube 20 forms negative pressure environment, makes the water in the water tank 40 enter Venturi tube 20 through water sucti...

Embodiment 2

[0063] This embodiment also provides a new type of respirator, such as Figure 3-4 As shown, it includes the above-mentioned novel breathing purification device, and also includes a mask; the mask sequentially includes an inner filter layer 110 and an outer filter layer 120 from the inside to the outside; an inner cavity 130 is formed between the inner filter layer 110 and the outer filter layer 120, and the inner cavity 130 is communicated with the outlet of the ventilation duct; the air introduced by the ventilation duct enters the inner cavity 130 and passes through the inner filter layer 110 for artificial respiration; the outside air can also enter the inner cavity 130 through the outer filter layer 120 and pass through the inner filter layer 110 for artificial respiration. For artificial breathing; artificially breathed air can be discharged out of the mask through the inner filter layer 110 and the outer filter layer 120 in sequence.

Abstract

The invention provides a novel respiratory purification device and a novel respirator, and relates to the technical field of dust-proof appliances. The novel respiratory purification device comprisesan air inducing device, a wetting device, a centrifugal device and a ventilation pipeline. The outlet of the air inducing device communicates with the inlet of the ventilation pipeline, the centrifugal device is arranged in the ventilation pipeline, the wetting device is arranged between the air inducing device and the centrifugal device, and the outlet of the ventilation pipeline communicates with an inner cavity of a mask. Air discharged from the outlet of the air inducing device passes through the wetting device and the centrifugal device in sequence, and flows through the ventilation pipeto the inner cavity of the mask. The wetting device comprises a Venturi tube and a water tank, the Venturi tube communicates with the water tank through a water suction pipe, the Venturi tube can forma negative-pressure environment, so that water in the water tank enters the Venturi tube through the water suction pipe, the air in the Venturi tube is wetted, and the technical problems that the function of a device used for breathing purification in the prior art is relatively deficient and imperfect are relieved.

Description

technical field [0001] The invention relates to the technical field of dustproof appliances, in particular to a novel respiratory purification device and a novel respirator. Background technique [0002] In factories and other similar spaces and areas with serious air pollution, the staff need to wear dust masks to ensure that dust, smoke and other impurities in the environment cannot invade the human respiratory tract and reduce the chance of staff being infected. Ensure the personal safety of staff. Therefore, dust masks, gas masks and other appliances used to protect the respiratory tract of workers are in great demand. In order to better realize and ensure the personal safety of workers, the structural performance and use of dust masks and gas masks Functional requirements are high. For example, these dust masks and gas masks used for dust prevention not only need to have good dust-proof and anti-virus energy supply, but also need to have good ventilation performance t...
