A first through hole 110 and two second through holes 120 are formed at the lower end of the large-volume protective clothing body 100 , and the two second through holes 120 are respectively formed on both sides of the first through hole 110 . The first through hole 110 is used for passing through the upper body of the human body, and the second through hole 120 is used for passing through the human hand. When the user uses the positive pressure droplet protective clothing, first open the first through hole 110 and insert the head and both hands into the first through hole 110, and then put the two hands through the second through hole 120 respectively. out.

The large-volume protective clothing body 100 in the present invention is also provided with two reverse gloves 130 facing the large-volume protective clothing body 100. The reverse gloves 130 are correspondingly formed in front of the upper body of the human body. 130 is used for when the user who wears the positive pressure droplet protective suit needs to eat, drink or drink water, the user first inserts the food or object into the first through hole 110, and then inserts his hand into the reverse glove 130. Corresponding operations are carried out inside, which greatly facilitates the users who use the positive pressure droplet protective clothing. Users can eat, drink, etc. in a clean space without taking off the protective clothing, which effectively protects the safety of users. , and meet the dietary needs of users.

In the present invention, the reverse gloves 130 are preferably formed integrally with the large-volume protective clothing body 100 , and the reverse gloves 130 extend toward the large-volume protective clothing body 100 after forming an opening on the large-volume protective clothing body 100 to close to the large-volume protective clothing body 100 . The position of the mouth and nose of the human body, so that the user can put his hand into the reverse glove 130 to perform corresponding operations.

As a further improvement of the present invention, the large-volume protective clothing body 100 is further provided with an elastic buckle 140 at the positions of the first through hole 110 and the second through hole 120 , and the elastic buckle 140 is used for the first through hole 110 and the opening and closing of the second through hole 120, when the user wears or takes off the positive pressure droplet protective clothing, the elastic buckle 140 is opened to open the first through hole 110 and the second through hole 120; when using The user puts on the positive pressure droplet protective clothing and closes the elastic buckle 140 to make the first through hole 110 and the second through hole 120 fit with the human body, so as to ensure that the large-volume protective clothing body 100 is in the air when the air blower 300 blows air. Bulge and expand under positive pressure. More preferably, there are two elastic buckles 140 of the first through hole 110, which are respectively formed on the lateral position of the human body, and one elastic buckle 140 of the second through hole 120 is formed correspondingly on the human arm. inside position.
