Detailed Implementation

[0015] like Figures 1-3As shown, a front panel structure and a water purifier are disclosed. The front panel 1 has a display window 5 at its front end, and a display screen 2 is inserted inside the display window 5. Positioning posts 6 are fixed to the rear end of the front panel 1 around the display window 5. Mounting seats 3 are fixed to the rear end of the display screen 2 around its perimeter. A through hole 4 is formed in the center of the mounting seat 3, which is flush against the rear of the front panel 1. The positioning posts 6 are interlocked with the through hole 4. A collar 8 is sleeved on the outside of the positioning posts 6, with its front end flush against the rear end of the mounting seat 3. Connecting rods 7 are fixed between adjacent collars 8. An annular boss 9 is fixed to the rear end of the front panel 1 outside the connecting rods 7. Locking blocks 14 are fixed to the outer sides of the connecting rods 7 at the four corners. A pair of locking slots 13 are formed on the left and right sides of the rear end of the annular boss 9. The locking blocks 14 are inserted into and engaged with the locking slots 13. The inner wall of the slot 13 has an insertion hole, and the slot 14 has an inner cavity. The insertion block 15 is slidably connected inside the inner cavity. The insertion block 15 is inserted into the insertion hole, and a spring 18 is connected between the insertion block 15 and the inner wall of the inner cavity. When installing the display screen 2, the through hole 4 of the mounting base 3 is aligned with the positioning post 6 of the front panel 1 and inserted. In this way, the display screen 2 will be accurately inserted into the display window 5. Then, the collar 8 is put on the outside of the positioning post 6 and is close to the rear end of the mounting base 3. At this time, the connecting rod 7 connecting the collars 8 is located inside the annular boss 9, and the slot 14 outside the connecting rod 7 is inserted into the slot 13 of the annular boss 9. In this process, the insertion block 15 needs to be moved into the inner cavity and the spring 18 needs to be squeezed. After the slot 14 is inserted into the slot 13 until the insertion block 15 corresponds to the insertion hole, the spring 18 returns to its original position and pushes the insertion block 15 out of the inner cavity and through the insertion hole, so as to limit the position of the display screen 2. This makes the installation quick and convenient.

[0016] The rear end of the locking block 14 has a slide rail 16, and the rear end of the insert block 15 is fixed with a slider 17. The rear part of the slider 17 extends out of the slide rail 16 and is slidably connected to the slide rail 16. A connecting rod 11 is fixed between the rear ends of the sliders 17 on the same vertical line. The connecting rod 11 is located behind the annular boss 9. The surface of the connecting rod 11 is provided with anti-slip protrusions 12. When disassembling the display screen 2, the two connecting rods 11 are pushed to close the distance. At this time, the connecting rod 11 drives the slider 17 to slide along the slide rail 16. 17 drives the insert 15 into the inner cavity and squeezes the spring 18. Then pull the connecting rod 11 to move the locking block 14 out of the slot 13 and the collar 8 out of the positioning post 6. Its anti-slip protrusion 12 can play an anti-slip role when pushing and pulling the connecting rod 11, thereby moving the collar 8 away from the mounting seat 3. Then the mounting seat 3 can be moved away from the outside of the positioning post 6. At this time, the display screen 2 can be pulled out of the display screen window 5, so that the disassembly of the display screen 2 is also quick. This facilitates the installation and subsequent maintenance and replacement of the display screen 2.

[0017] The annular boss 9 has an arc groove 10 around its inner wall. The collar 8 is inserted into the arc groove 10. When the collar 8 is placed on the outside of the positioning post 6, the collar 8 will slide into the arc groove 10 of the annular boss 9, which can accurately position the collar 8.
