新冠肺炎疫情期间，在餐厅用餐怎么才能更安全？为了降低风险，以色列发明者研发了一种有“机械嘴”的口罩，可以让你外出用餐时也不用摘口罩。 Israeli inventors have developed a coronavirus mask with a remote control mouth that lets diners eat food without taking it off, a device they say could make a visit to a restaurant less risky. 以色列发明家发明了一种预防新型冠状病毒的口罩，这种口罩有一个可以远程控制的开口，可以让用餐者不用取下口罩就能用餐。发明者说，这种口罩可以降低去餐厅就餐的风险。 A squeeze of a lever, much like a cyclist operates a handbrake, opens a slot in the front of the mask so that food can pass through. 用餐者只需挤压控制杆，就像骑自行车的时候捏手刹一样，口罩前面就会打开一个狭槽，人们就可以通过把食物送进嘴里。 |
