[0030] Referring to Figure 1 as shown, the present utility model provides a technical solution: A pressure controller provided with a filtering device, including a pressure controller body 1, the surface of the pressure controller body 1 is communicated with a water inlet pipe 2 and a water outlet pipe 3, the surface of the water inlet pipe 2 is provided with a filtering structure 4, and the side wall of the installation shell 401 is provided with a covering structure 5.
[0031] Next, specifically describe the specific settings and functions of its filtering structure 4 and covering structure 5.
[0032] Referring toFigures 1 - 6 As shown in the figure, in this embodiment: The filtering structure 4 includes a mounting shell 401 fixedly connected to the surface of the water inlet pipe 2. A connecting cap 402 is threadedly connected to the outside of the mounting shell 401. Four first through grooves 406 are provided inside the mounting shell 401. A filter screen 403 is slidably mounted inside the mounting shell 401. A number of spherical annular grooves 412 are provided on the surface of the filter screen 403. Impurities can be temporarily accumulated inside the spherical annular grooves 412, increasing the filtering surface during the use of the filter screen 403, thereby improving the permeability effect during the use of the filter screen 403. A rotating shaft 413 is rotatably connected inside the filter screen 403. Three brush strips 409 are fixedly connected to the side wall of the rotating shaft 413. A number of bristles 410 are fixedly connected to the surfaces of the three brush strips 409. The bristles 410 on the brush strips 409 can clean the impurities on the surface of the filter screen 403, and the cleaned impurities can fall into the spherical annular grooves 412 for accumulation. Three fan blades 405 are fixedly connected to the side wall of the rotating shaft 413. The water source will impact the fan blades 405 to rotate, and then the driving rotation of the brush strips 409 can be realized.
[0033] A limiting ring 404 is rotatably connected inside the mounting shell 401. A number of anti-slip grooves 407 are evenly provided inside the limiting ring 404. A number of second through grooves 408 are provided inside the limiting ring 404. The anti-slip grooves 407 on the limiting ring 404 increase the friction between the hand and the limiting ring 404, thus facilitating the driving rotation of the limiting ring 404. A number of connecting blocks 411 are fixedly connected to the side wall of the filter screen 403. When the first through grooves 406 on the limiting ring 404 rotate to the position overlapping with the second through grooves 408, the flexible removal and storage of the filter screen 403 with the connecting blocks 411 can be realized, facilitating the regular treatment of the impurities inside the filter screen 403.
[0034] Refer to Figures 1 - 3 As shown in the figure, specifically, the covering structure 5 includes a positioning strip 52 fixedly connected to the outer side wall. A rotating rod 53 is rotatably connected inside the positioning strip 52. A limiting plate 54 is fixedly connected to the side wall of the rotating rod 53. A covering plate 51 is fixedly connected to the side wall of the limiting plate 54. The upper surface of the covering plate 51 is a spherical surface. The rotating rod 53 will drive the limiting plate 54 and the covering plate 51 to rotate simultaneously. At this time, the flexible covering of the port position of the mounting shell 401 can be realized, and the impurities will slide down along the spherical surface of the covering plate 51, thus avoiding the phenomenon that the impurities directly fall into the water inlet pipe 2. A rotating block 55 is fixedly connected to the upper end of the rotating rod 53. Rotating the rotating block 55, the setting of the rotating block 55 facilitates the twisting of the rotating rod 53.
[0035] Working principle: by setting the filter screen 403 with a spherical annular groove 412, impurities can be temporarily accumulated on the inner side of the spherical annular groove 412, which increases the filtering surface of the filter screen 403 during use, thereby improving the permeability of the filter screen 403 during use. By setting the connecting cap 402, normal docking work can be performed with the help of the connecting cap 402 and the threaded port. In the process of water source entering the water inlet pipe 2, the water source will impact the fan blade 405 to rotate, thereby realizing the driving work of the brush strip 409. The bristles 410 on the brush strip 409 can realize the cleaning work of impurities on the surface of the filter screen 403, and the cleaned impurities can fall into the inner side of the spherical annular groove 412 and accumulate, thereby further improving the permeability of the filter screen 403 during use, and rotating the inner side of the mounting shell 401 The limiting ring 404 and the anti-slip groove 407 on the limiting ring 404 increase the friction between the hand and the limiting ring 404, thereby facilitating the driving and rotating work of the limiting ring 404. When the first through groove 406 on the limiting ring 404 is rotated to a position overlapping with the second through groove 408, the filter screen 403 with the connecting block 411 can be flexibly taken out and stored, which facilitates the regular treatment of impurities inside the filter screen 403. Conversely, the first through groove 406 and the second through groove 408 are staggered to realize the installation of the filter screen 403. By setting the filtering structure 4, a structure different from the traditional filter screen 403 is set, which avoids the phenomenon of impurities accumulating on the traditional filter screen 403 and affecting the permeability of the filter screen 403, thereby improving the performance of the pressure controller body 1 to a certain extent.
[0036] After the filter screen 403 is lifted, the rotating block 55 is rotated. The setting of the rotating block 55 facilitates the twisting of the rotating rod 53, and the rotating rod 53 will drive the limit plate 54 and the shield plate 51 to rotate at the same time. At this time, the flexible covering of the port position of the mounting shell 401 can be achieved, and impurities will slide along the spherical surface of the shield plate 51, thereby avoiding the phenomenon of impurities falling directly into the inside of the water inlet pipe 2, and improving the phenomenon of impurities falling into the water inlet pipe 2 when the filter screen 403 is lifted and moved, or when the water inlet pipe 2 is covered for a long time. The performance of the pressure controller body 1 is further improved, and the temporary covering and protection of the water inlet pipe 2 nozzle position is facilitated by setting the covering structure 5, thereby improving the protection effect of the water inlet pipe 2 nozzle.
