如图1至图6所示，一种消音电磁阀，包括阀体1和阀芯6。阀体1具有阀腔2、自阀体外表面的第一开口35向内延伸到阀腔2形成的排气通道3、自阀体外表面的第二开口41向内延伸到阀腔2形成的充气通道4及自阀体外表面的第三开口51向内延伸到阀腔2形成的供气通道5。
排气通道3具有内径较小的第一管腔32及内径较大的消音腔33。第一管腔32是等内径的直线型腔室，第一开口35设于第一管腔32的顶部，第一管腔32的底部和消音腔33贯通。消音腔33的截面大致呈方形，其具有相对的腔壁34，自腔壁34的中部相向拱起而在两个拱起部之间形成内径缩小的颈部36。消音腔33腔底的角落处贯穿设有第一阀口31，消音腔33通过该第一阀口31连接阀腔2，第一阀口31的内径小于第一管腔32的内径。第一阀口31的轴线可以与第一管腔32的轴线平行。消音腔33具有圆弧倒角37，即消音腔的各个棱具有圆弧倒角。消音腔33内充填有消音材料体9，该消音材料体9的形状大小与消音腔33匹配。

对于消音电磁阀，消音腔和消音材料体集成在电磁阀内部。消音腔内填充吸音棉，排放出的气体因压力必须经过吸音棉排出，吸音棉自身有无数不同大小的孔，反复吸收不同频率的声音。同时，消音腔腔底的角落处设置第一阀口，改变了气流方向，进一步提高了降低噪音的效果。第一管腔的内径大于第一阀口的内径，且消音腔的内径大于第一管腔的内径，在排出气体流量不变的情况，气流经过该内径较大的消音腔和第一管腔时，能够降低气流的速度，从而能够降低噪音，并将高频噪音降为低频的噪音，提高人体的接受度。
一种穿戴设备，其能够穿戴在用户的头部、面部、躯干和四肢等身体部位，其包括壳体、供气设备及用气设备，供气设备及用气设备安装在壳体内部，供气设备和用气设备通过上述消音电磁阀连接，消音电磁阀的供气通道与供气设备连接，消音电磁阀的充气通道与用气设备连接。该供气设备如气泵，该用气设备如气囊。通过消音电磁阀，实现对气囊的充放气控制，进而实现对用户身体部位的气压按摩。
以上仅为本申请的可选实施例而已，并不用于限制本申请。对于本领域的技术人员来说，本申请可以有各种更改和变化。凡在本申请的精神和原则之内，所作的任何修改、等同替换、改进等，均应包含在本申请的权利要求范围之内。
