[0037] Working principle: Before using this quick-release anti-blocking shower head, you need to check the overall condition of the device to make sure it can work normally. Figure 1 - Figure 8 As shown, when installing the two cleaned filter screens 214, firstly, the rotating disk 203 is inserted into the stepped hole 209, so that the first pressing ring 210 will fit the vertical section of the stepped hole 209, and at the same time, the limiting column 206 slides into the limiting groove 207, and as the limiting column 206 slides in the limiting groove 207, the rotating disk 203 rotates and moves horizontally, so that the rotating disk 203 pushes the second pressing ring 212 to cooperate with the first pressing ring 210 that cannot move to squeeze the rubber ring 211, so that the rubber ring 211 is deformed due to the squeezing and fits tightly against the installation column 208 and the stepped hole 208. 9 inner wall, forming a sealing effect, as long as the extrusion of the rubber ring 211 does not disappear, the sealing always exists, when the limit column 206 slides into the end of the limit groove 207, the crank 204 is rotated downward to squeeze the crank 204 and the plastic hook plate 205, so that the plastic hook plate 205 is deformed and clamps the crank 204, and finally the position of the rotating disk 203 cannot be changed, thereby ensuring that the rubber ring 211 is squeezed, thereby ensuring the sealing, canceling the installation function of the rubber ring 211, reducing its wear speed, and the snap-fit ​​installation allows the filter 214 to be quickly disassembled and cleaned;

[0038] When the shower head needs to be used, the sliding sleeve 302 is first pulled upwards to squeeze the spring 303 and make the middle protrusion of the sliding sleeve 302 cancel the limit on the limiting bead 306, and then the connecting sleeve 307 is inserted into the installation tube 304, so that the installation tube 304 is tightly attached to the inner side of the connecting head 301. During this process, the connecting sleeve 307 will squeeze the limiting bead 306 to move and avoid the limiting bead 306 from interfering. Then the sliding sleeve 302 is loosened to make the spring 303 push the sliding sleeve 302 to reset, so that the raised inclined surface in the middle of the sliding sleeve 302 will push the limiting bead 306 back to the limiting hole 305, and make the limiting bead 306 engage with the groove 308; so that the shower head can avoid the use of a threaded structure and achieve quick installation.
