BRIEF DESCRIPTION OF DRAWINGS
[25] The technical solution in the embodiments of the present invention will be described clearly and completely below in combination with the accompanying drawings in the embodiments. It is apparent that the described embodiments are only a part of, rather than all of, embodiments of the present invention. Based on the embodiments of the present invention, all other embodiments made by those of ordinary skill in the art without making creative efforts should fall into the scope of the present invention.
[26] Example 1:
[27] Referring to FIG. 1 to FIG. 4, a dampproof air-tight door includes a door body 1 and a seal ring 2 arranged on the door body 1, and further includes a door pocket matched with the door body 1. The technical solution is prior art, which is not shown in the figure. The door body 1 and the door pocket is rotatably connected by arranging hinges. The technical solution is prior art, which is not shown in the figure. During work, the seal ring 2 blocks a crevice between the door body 1 and the door pocket, so that a condition that moisture passes through the crevice between the door body 1 and the door pocket is reduced. When the door body 1 rotates around the hinges, the door body 1 and the door pocket apply frictional forces to the seal ring 2, and the seal ring 2 is partially worn.
[28] Referring to FIG. 1 and FIG. 3, an air bag 3 is arranged on a side of the door body 1, one side of the air bag 3 directly faces the hinges, the limiting mechanism is arranged on the side of the air bag 3 close to the door body 1, an air pipe 4 is assembled on an outer side of the air bag 3, one end of the air pipe 4 penetrates through the door body 1 and is provided with a micro air pump 5, the micro air pump 5 is arranged on an outer side of the door body 1, an electric air valve 6 is arranged on a side surface of the air pipe 4, and a controller 7 for controlling the micro air pump 5 and the electric air valve 6 is further arranged on an outer side of the door body 1.
After the seal ring 2 is used for a period of time, the micro air pump 5 and the electric air valve 6 are controlled by the controller 7 to work intermittently, the micro air pump 5 blows quantified air into the air bag 3, and then the electric air valve 6 closes the air pipe 4, so that gas in the air bag 3 is prevented from leaking from the air pipe 4.
Meanwhile, the air bag 3 swells to extrude the seal ring 2, the seal ring 2 deforms, and the air bag 3 fills a crevice formed between the seal ring 2 and the door body 1 as a result of deformation, so that it is convenient to push the seal ring 2 to compensate a worn part of the seal ring 2, thereby reducing decline in the airtightness of the seal ring 5 as aresult of wear, and it is convenient for the seal ring 2 to cling to the door pocket.
[29] Referring to FIG. 1 and FIG. 2, a limiting mechanism includes two groups of limiting rods 9 fixedly mounted on the outer side of the air bag 3, mounting grooves 8 are inserted into the side of each group of limiting rods 9 away from the air bag 3, the mounting grooves 8 are formed in one side of the door body 1, and the two groups of limiting rods 9 are respectively arranged on both sides in the mounting grooves 8.
When the air bag 3 swells, the limiting rods 9 are driven by the air bag 3 to slide in the mounting grooves 8, so that the mounting grooves 8 and the limiting rods 9 apply opposite support forces to the air bag 3 to relieve a trend that the air bag 3 moves laterally relative to the door body 1, thereby reducing a condition that the air bag 3 is separated from the door body 1 and the seal ring 2 as it moves laterally.
[30] Referring to FIG. 2 and FIG. 3, a box body 10 is sleeved outside the micro air pump 5, and the box body 10 is made of a foam plate, so that it is convenient for the box body 10 to absorb noise. The box body 10 is fixedly mounted on the door body 1, and a plurality of air inlets 11 are formed in the side of the box body 10 away from the air pipe 4. When the micro air pump 5 generates noise, the noise is absorbed by the box body 10. Meanwhile, air flows into the air pipe 4 and the micro air pump 5 along the air inlets 11 in the box body 10, so that it is convenient to convey air to the micro air pump 5 while weakening the noise of the micro air pump 5.
[31] Referring to FIG. 3, a liner 12 is arranged on an inner wall of the box body 10, and the liner 12 is made of sponge, so that it is convenient for the liner 12 to absorb noise. A structure of the liner 12 is “U”-shaped, and an opening direction of the liner 12 is away from the air inlets 11. When there is noise in the box body 10, partial noise is absorbed by the liner 12. The gas in the box body 10 flows along the liner 12, so that a condition that the liner 12 hinders the air pipe 4 and the micro air pump 5 to inhale air is avoided.
[32] Referring to FIG. 2 and FIG. 4, two adjacent limiting rods 9 are connected by arranging a rubber band 13, and the rubber band 13 is located between the door body 1 and the air bag 3. When the limiting rods 9 displace relative to the mounting grooves 8, the limiting rods 9 are tensioned as the air bag 3 is matched with the rubber band 13, so that a condition that the limiting rods 9 are separated from the mounting grooves 8 is reduced.
[33] Referring to FIG. 2 and FIG. 3, pressure sensors 14 are arranged at both ends of each of the mounting grooves 8, the ends of the pressure sensors 14 away from the door body 1 cling to the seal ring 2, the pressure sensors 14 are electrically connected with the controller 7, and the pressure sensors 14 monitor stress of sections of the seal ring 2 in the mounting grooves 8. When the seal ring 2 is partially worn, the seal ring 2 deforms towards a worn area, so that the stress on the inner side of the seal ring 2 is decreased, and an extrusion force applied by the seal ring 2 to the pressure sensors 14 is reduced. When a detected numerical value is decreased to a certain range, the micro air pump 5 is controlled by the controller 7 to blow quantified air into the air bag 3 to compensate wear of the seal ring 2, so that it is convenient to inflate the air bag 3 automatically.
[34] A working principle is as follows: during work, the seal ring 2 blocks a crevice between the door body 1 and the door pocket, so that a condition that moisture passes through the crevice between the door body 1 and the door pocket is reduced. When the door body 1 rotates around the hinges, the door body 1 and the door pocket apply frictional forces to the seal ring 2, and the seal ring 2 is partially worn.
[35] Meanwhile, the pressure sensors 14 monitor stress of sections of the seal ring 2 in the mounting grooves 8. When the seal ring 2 is partially worn, the seal ring 2 deforms towards a worn area, so that the stress on the inner side of the seal ring 2 is decreased, and an extrusion force applied by the seal ring 2 to the pressure sensors 14 is reduced. When a detected numerical value is decreased to a certain range, the micro air pump 5 and the electric air valve 6 are controlled by the controller 7 to work intermittently, the micro air pump 5 blows quantified air into the air bag 3, and then the electric air valve 6 closes the air pipe 4, so that gas in the air bag 3 is prevented from leaking from the air pipe 4. Meanwhile, the air bag 3 swells to extrude the seal ring 2, the seal ring 2 deforms, and the air bag 3 fills a crevice formed between the seal ring 2 and the door body 1 as a result of deformation, so that it is convenient to push the seal ring 2 to compensate a worn part of the seal ring 2, and the pushing amount of the air bag 3 every time is not smaller than the wear amount of the seal ring 2, thereby reducing decline in the airtightness of the seal ring 2 as a result of wear, and it is convenient for the seal ring 2 to cling to the door pocket.
[36] When the air bag 3 swells, the limiting rods 9 are driven by the air bag 3 to slide in the mounting grooves 8, so that the mounting grooves 8 and the limiting rods 9 apply opposite support forces to the air bag 3 to relieve a trend that the air bag 3 moves laterally relative to the door body 1, thereby reducing a condition that the air bag 3 is separated from the door body 1 and the seal ring 2 as it moves laterally.
[37] The above-mentioned contents are only the preferred specific embodiments of the present invention, but the protection scope of of the present invention is not limited to those embodiments. Equivalent changes or modifications made by those skilled in the art within the technical scope of the present invention according to the technical solutions and concepts thereof of the present invention shall fall into the protection scope of the present invention.
