[0025] The first filter cotton layer 10 is installed close to the air inlet of the gas filter 6 , and the second filter cotton layer 11 is installed away from the air inlet of the gas filter 6 , and the density of the first filter cotton layer 10 is less than the density of the second filter cotton layer 11 .

[0026] The gas filter layer 9 filled between the first filter cotton layer 10 and the second filter cotton layer 11 is activated carbon.

[0027] When two groups of filter components 7 are provided, when using the above-mentioned cardiopulmonary resuscitation rescue breathing device, the corresponding breathing mask 4 is installed on the patient's face, and an elastic band is provided on the breathing mask, and the breathing mask 4 is fixed to the patient's face position by the elastic band.

[0028] Start to press the airbag 2 manually downward, and the gas enters from the air inlet on the gas filter 6, passes through the first filter cotton layer 10 and the second filter cotton layer 11 in the gas filter 6 and the activated carbon filled between the first filter cotton layer 10 and the second filter cotton layer 11 to filter and absorb odors. The above two filter cotton layers with different densities can filter the dust in the air step by step in time, and the activated carbon absorbs the odor in the air at the same time. The filtered gas enters the outlet pipe 3 and is finally delivered to the patient's body through the breathing mask 4. The above structure can ensure that fresh air is delivered to the patient's body.

[0029] Embodiment 2:

[0030] The filter component 7 is provided with three groups, namely a first filter cotton layer 10, a second filter cotton layer 11 and a third filter cotton layer 12.
