Title:
SILENCING ELECTROMAGNETIC VALVE AND WEARABLE DEVICE
Document Type and Number:
WIPO Patent Application WO/2020/258916
Kind Code:
A1
Abstract:
Disclosed are a silencing electromagnetic valve and a wearable device. The silencing electromagnetic valve comprises a valve body (1), a valve core (6) and a silencing material body (9), wherein the valve body is provided with a valve cavity (2), an air discharge channel (3) capable of discharging an airflow to the ambient atmosphere, an inflation channel (4) capable of being connected to an air consumption device (8), and an air supply channel (5) capable of being connected to an air supply device (7); the valve core is mounted in the valve cavity and can enable the inflation channel to be switched so as to alternatively communicate with the air discharge channel or the air supply channel; the air discharge channel is provided with a first pipe cavity (32) with a smaller inner diameter, and a silencing cavity (33) with a larger inner diameter, and the bottom of the first pipe cavity communicates with the silencing cavity; the silencing cavity is filled with the silencing material body; and the inflation channel is provided with a second pipe cavity (42), and the silencing cavity is located between the first pipe cavity and the second pipe cavity. During air discharge, the silencing material body in the silencing cavity can be used for performing silencing noise reduction on an airflow, such that an air discharge sound can be effectively reduced.
