[0026] In order to make the purpose, technical solutions and advantages of the present invention more clear, the present invention is further described in detail below with reference to the accompanying drawings and embodiments.

[0027] In one embodiment, Figure 1-Figure 7 As shown, a high-concentration medical molecular sieve oxygen generator includes a base 101, on which a molecular sieve oxygen generator unit is installed.

The pulling structure facilitates the movement of the oxygen production equipment. When the molecular sieve is maintained or replaced, the self-unlocking structure is triggered by the pulling structure to separate the shell 102 from the base 101, which is conducive to the rapid maintenance and replacement of the molecular sieve and ensures the concentration of oxygen produced by the oxygen production equipment.

[0029] In one embodiment, Figure 4 As shown, the locking structure includes a locking plate 301 rotatably connected to the fixed plate 103, one end of the locking plate 301 is connected to one end of the spring 303, and the other end of the locking plate 301 is connected to a locking block 304. A locking block 302 that cooperates with the locking block 304 is provided in the shell 102, and the other end of the spring 303 is connected to the fixed plate 103. When the shell 102 is installed, the locking block 302 squeezes the locking block 304 to rotate the locking plate 301. After the shell 102 is installed in place, under the action of the spring 303, the locking block 304 clamps the locking block 302 to achieve locking.

[0030] In one embodiment, Figure 1 、 Figure 2 and Figure 6 As shown, the lifting structure includes a sliding groove 201 provided on the fixed plate 103, a slider 203 is slidingly provided in the sliding groove 201, and the slider 203 is connected to the handle 205 through a connecting column 204. A limiting groove 207 is provided on the shell 102, and the position of the limiting groove 207 corresponds to the sliding groove 201. In the initial state, the handle 205 is in a vertical state. Under the action of gravity, the handle 205 contacts the upper surface of the oxygen generator, which is beneficial to reducing the space occupied by the handle 205. When moving the oxygen generator, the handle 205 is lifted, and the slider 203 slides to the upper end of the sliding groove 201, and the base 101 is pulled by the fixed plate 103 to realize the overall movement of the oxygen generator.

[0031] In one embodiment, Figure 4 and Figure 6 As shown, a disengagement opening 202 is provided at one end of the sliding groove 201, and the width of the disengagement opening 202 is smaller than the width of the sliding groove 201. The self-unlocking structure includes a through-hole 305 provided on the fixed plate 103, and the position of the through-hole 305 corresponds to the position of the disengagement opening 202. A top block 306 is provided in the through-hole 305 so as to slide. One end of the top block 306 is exposed from the disengagement opening 202. The top block 306 is connected to a movable column 308 through a connecting rod 307. The movable column 308 is slidably provided on the locking plate 301, and the movable column 308 is connected to the locking plate 301. 01 Rotational contact. When removing the housing 102, first lift the handle 205, then rotate the handle 205 to rotate the slider 203 90 degrees in the sliding groove 201, hold the connecting column 204 and lift the slider 203, the slider 203 squeezes the top block 306, and the top block 306 moves the locking block 304 away from the locking block 302 through the connecting rod 307 and the movable column 308. At this time, the locking structure is unlocked, and the slider 203 is separated from the sliding groove 201 from the disengagement port 202. The handle 205 is removed together with the housing 102 to complete the disassembly.

After the slider 203 rotates 90 degrees, the cylindrical surfaces play a guiding role, making it easier for the slider 203 to escape from the sliding groove 201 at the escape opening 202.

[0034] In one embodiment, Figure 2 and Figure 7 As shown, a limiting block 206 is connected through the connecting column 204, and the limiting block 206 is slidably set in the limiting groove 207. The limiting block 206 matches the limiting groove 207, which is beneficial to improving the stability of the handle 205 when lifting and lowering, that is, it is beneficial to improving the stability of the oxygen production equipment when moving.

[0035] The above embodiment discloses a high-concentration medical molecular sieve oxygen generator, wherein, when installing the shell 102, the locking block 302 squeezes the locking block 304, causing the locking plate 301 to rotate. After the shell 102 is installed in place, under the action of the spring 303, the locking block 304 is clamped on the locking block 302 to lock it. When removing the shell 102, first lift the handle 205, then rotate the handle 205 to rotate the slider 203 90 degrees in the sliding groove 201, hold the connecting column 204 and lift the slider 203, the slider 203 squeezes the top block 306, and the top block 306 moves the locking block 304 away from the locking block 302 through the connecting rod 307 and the movable column 308. At this time, the locking structure is unlocked, and at the same time, the slider 203 is separated from the sliding groove 201 from the disengagement port 202, and the handle 205 is removed together with the shell 102, completing the disassembly of the shell 102, which is convenient and quick.
