A ventilation respiration insole with an air augmentation effect is provided. The insole includes an insole body (1) wherein an air augmentation apparatus (2) and a compressed air source supply device (7) are mounted. The air augmentation apparatus (2) comprises an air inlet pipe (21) and an air outlet pipe (22) which are connected in sequence. The air inlet pipe (21) absorbs the air at the bottom of the insole body (1). The air outlet pipe (22) is communicated with the outside of the insole body (1). The lumens of the air inlet pipe (21) and the air outlet pipe (22) are joined together and form a flow channel (5). An air inlet gap (6) is formed between the connecting ends of the air inlet pipe (21) and the air outlet pipe (22). One end of the air inlet gap (6) accepts the compressed air which comes from the compressed air source supply device (7). The other end is an air outlet port (61) connected with the flow channel (5). The compressed air flows to the outlet pipe (22) through the air inlet gap (6) so as to form the Coanda effect, so that the air absorbed by the inlet pipe (21) is exhausted to the outside of the insole body (1) by the air outlet pipe (22). The insole uses the Coanda effect, and a small volume of compressed air can pull a large volume of ambient air, so that the ventilation effect of the insole is excellent. |
