As shown in FIGS. 1 to 4, the uniformly distributed spraying device of sterilizing gas comprises: a housing 201, and a movable plug 202 sliding along the inside of the housing 201, the movable plug 202 dividing the inside of the housing 201 into a main injection region 203 and an auxiliary injection region 204; an air inlet 205 of the shell 201 supplies air towards the auxiliary injection area 204, a main injection port 206 of the main injection area 203 is located on an end plate 207 of the shell 201, an auxiliary injection port 208 of the auxiliary injection area 204 is located on a circumferential surface 209 of the shell 201, a reset device is arranged in the main injection area 203 and used for balancing with the air pressure in the auxiliary injection area 204 and controlling the position of the movable plug body 202, and the movable plug body 202 realizes the opening and closing of the main injection port 206 and the auxiliary injection port 208 at different positions.

In the invention, different injection positions are required to be obtained, so compared with the existing valve body structure or injection device structure, the main injection port 206 and the auxiliary injection port 208 are respectively arranged to inject the sterilizing gas in different directions, the switching between the main injection port 206 and the auxiliary injection port 208 is realized by balancing the gas pressure in the reset device and the auxiliary injection area 204, the automatic adjustment of the positions can be realized, the automatic switching between the main injection port 206 and the auxiliary injection port 208 can be realized by controlling the air inlet pressure, and the control difficulty is reduced.

As shown in fig. 5 to 13, as a preferred embodiment of the above embodiment, a plurality of air ducts 210 are distributed on a first end surface of the movable plug 202 facing the main injection region 203, where the distribution uniformity needs to be ensured as much as possible, so as to ensure more uniform disinfection at the position, and the air ducts 210 realize the conduction of air through holes 211 penetrating through the movable plug 202; the end plate 207 is provided with a stopper 212 for closing the end of the air duct 210, and the first end surface is further provided with an annular body 213, and the annular body 213 is used for closing the auxiliary injection port 208 in the main injection region 203. In order to ensure the plugging effect of the plug 212, the end part of the plug 212 is of a conical structure, and the end part of the air duct 210 is matched with the conical structure, so that the sealing effect is ensured, and the guiding effect can be achieved.

As shown in the figure, after the gas enters the main injection region 203 from the through hole 211 and the gas guide tube 210, when the air guide tube 210 is not blocked by the plug 212, the gas is injected from the main injection port 206 and acts on the article, at this time, the annular body 213 seals the auxiliary injection port 208, so as to avoid the gas leakage, and in order to improve the sealing effect, referring to fig. 11, a sealing structure 217 is arranged between both ends of the annular body 213 in the moving direction of the movable plug 202 and the housing 201, wherein the sealing structure 217 may be a sealing ring embedded in a sealing groove on the periphery of the annular body 213, or a sealing ring embedded in a sealing groove on the inner wall of the circumferential surface 209, or both of them may be arranged. In the implementation process, it is necessary to ensure that the flow area of the air inlet 205 is larger than the sum of the flow areas of the through holes 211, so that the pressure of the air in the auxiliary injection region 204 is gradually increased, and the movable plug 202 is squeezed and moved; when the air is moved to the auxiliary jet opening 208 and at least partially opened, the plug 212 is required to completely block the air duct 210, and at the moment, the air can rapidly flow out of the auxiliary jet opening 208 and disinfect articles at other positions only by enabling the flow area of the opened part of the auxiliary jet opening 208 to be larger than that of the air inlet 205; when the pressure in the auxiliary injection region 204 is released, the movable plug 202 is gradually returned by the returning means, so that the injection of the main injection port 206 is continuously performed. In the above process, there may be a process in which the main injection ports 206 and the auxiliary injection ports 208 simultaneously perform injection, without affecting the final object of the present invention.
