Abstract: An automatic heating vending machine including a storage space, a storage mechanism, a fetching mechanism, a gripping arm mechanism, a rotating disc mechanism and a heating mechanism are disclosed. The storage mechanism is installed in the storage space to store food. The fetching mechanism is installed in the storage space and disposed under the storage mechanism to catch the food. The gripping arm mechanism grips the food on the fetching mechanism. The rotating disc mechanism is disposed on one side of the gripping arm mechanism. The gripping arm mechanism grips the food and then places the food on the rotating disc mechanism. The heating mechanism is disposed above the rotating disc mechanism. After the food has been placed on the rotating disc mechanism, the rotating disc mechanism undergoes horizontal movement and vertical movement, allowing the food to be admitted to the heating mechanism and heated.

Abstract: A medical protective device is disclosed. The medical protective device includes a first cover and a second cover. The first cover includes a first plate and a negative pressure suction hole, wherein the first plate has a first hole. The second cover is adapted to be engaged under the first cover and to approach the mouth and the nose of a patient. The second cover includes a second plate and a plurality of extraction holes, wherein the second plate has a second hole in connection with the first hole. When the first cover and the second cover are engaged, a gap is present between the first cover and the second cover. Thus, infectious droplets produced by the mouth and the nose of the patient can be eliminated by the negative pressure suction hole through the plurality of extraction holes and the gap.
