Title:
EXHAUST SOLE AND IN-SHOE EXHAUST METHOD
Document Type and Number:
WIPO Patent Application WO/2022/166972
Kind Code:
A1
Abstract:
An exhaust sole, comprising a midsole (1) and an outsole (2). The lower surface of the midsole (1) is provided with an air compartment (11), an air inlet channel (12), and a one-way exhaust channel (13), and the air compartment (11) is arranged at the position of a heel; the air inlet channel (12) comprises dispersed air collecting channels (121) and an air guiding channel (122), the dispersed air collecting channels (121) are arranged at the front portion of the sole and provided with air inlet holes (123), and the air guiding channel (122) is connected with the dispersed air collecting channels (121) to the rear end of the air compartment (11); and the one-way exhaust channel (13) is provided with a Tesla valve structure, and is provided with one end connected to the front end of the air compartment (11) and the other end provided with an air outlet hole (131) penetrating the upper surface of the midsole (1), and the one-way exhaust channel (13) is in a high-resistance direction from the air outlet hole (131) to the air compartment (11). The one-way exhaust channel (13) having the Tesla valve structure implements one-way flowing of airflow by using a principle that branches of the airflow counteract mutually, and there is no moving part inside, so that the service life is long, and the reliability is high; and the exhaust sole has a simple manufacturing process, high efficiency, and low cost.
