[0029] Reference Figure 1-5The utility model provides an embodiment: a liquid injection device that is easy to disassemble and assemble, including a liquid injection filter 1 and a connecting pipe 14, the front and rear ends of the liquid injection filter 1 are fixedly connected to a first fixing plate 2, the inner wall of the first fixing plate 2 is slidably connected to a slider 3, the through holes of the slider 3 are slidably connected to a connecting long rod 4, the other end of the connecting long rod 4 is fixedly connected to a mounting block 5, the upper and lower inner walls of the mounting block 5 are fixedly connected to a fixing cylinder 6, the inner wall of the fixing cylinder 6 is fixedly connected to a spring 7, and the end of the spring 7 away from the fixing cylinder 6 is fixedly connected to a limiting rod 8. During the installation process, the liquid injection filter 1 is first kept at the same level as the connecting pipe 14, and then the connecting long rod 4 is moved outward through the slider 3, so that the connecting long rod 4 drives the mounting block 5 to move outward, and the liquid injection filter 1 is moved toward the connecting pipe 14. The locking cam 8 is then released and the locking cam 8 is released, ...

[0030] Further explanation, a connecting plate 17 is fixedly connected to the right side of the outer end of the slider 3, and a sleeve 9 is fixedly connected to the end of the connecting plate 17 away from the first fixed plate 2. A tension spring 10 is fixedly connected to the inner wall of the sleeve 9, and an n-shaped rod 11 is fixedly connected to the end of the tension spring 10 away from the sleeve 9. A plurality of engaging holes 12 are provided at the bottom of the outer end of the first fixed plate 2, and the inner diameter of the engaging hole 12 is adapted to the outer diameter of the n-shaped rod 11. The front and rear ends of the outer diameter of the connecting pipe 14 are fixedly connected to the second fixing plate 15, and the inner groove size of the second fixing plate 15 is larger than the sum of the outer diameters of the mounting block 5 and the two fixing cylinders 6. Limiting holes 16 are provided at the upper and lower ends of the second fixing plate 15, and the inner diameter size of the limiting hole 16 is adapted to the outer diameter size of the limiting rod 8. The left end of the connecting pipe 14 is fixedly connected to the valve 13, and the connecting pipe 1 The outer diameter of 4 is equal to the inner diameter of the liquid injection filter 1, so that the connecting tube 14 can be embedded in the interior of the liquid injection filter 1 and realize the connection process. Since the lengths of the connecting tubes 14 are different, the installation positions of the second fixing plate 15 are also different. In the installation process, the n-shaped rod 11 is first moved outward so that the other end of the n-shaped rod 11 is separated from the limit of the engaging hole 12, and then the slider 3 is adjusted left and right. Then, the force applied to the n-shaped rod 11 is canceled, and the tension of the tension spring 10 connected to the n-shaped rod 11 drives the n-shaped rod 11 to move inward, so that the other end of the n-shaped rod 11 is limited to other engaging holes 12, thereby achieving the purpose of adjustable installation of the second fixing plate 15 installed with different lengths and improving the usability of the device.

[0031] Working principle: During the installation process, first keep the liquid injection filter 1 and the connecting pipe 14 at the same level, then move the connecting long rod 4 outward through the slider 3, so that the connecting long rod 4 drives the mounting block 5 to move outward, and move the liquid injection filter 1 toward the connecting pipe 14. When the mounting block 5 and the groove of the second fixed plate 15 are kept at the same level, the connecting long rod 4 is moved inward on the slider 3, and at the same time, the limiting rod 8 on the mounting block 5 is squeezed, so that the mounting block 5 drives the limiting rod 8 to enter the groove of the second fixed plate 15, and the elastic force of the spring 7 connected to the limiting rod 8 drives the limiting rod 8 to reset, so that the limiting rod 8 limits the limiting hole 16, thereby realizing liquid injection. The filter 1 and the connecting tube 14 are installed, and when disassembled, the limiting rod 8 can be squeezed, and the connecting long rod 4 drives the mounting block 5 and the limiting rod 8 to move outward, so as to realize the disassembly process of the two. Because the lengths of the connecting tubes 14 are different, the installation positions of the second fixing plates 15 are also different. In the installation process, the n-shaped rod 11 is first moved outward so that the other end of the n-shaped rod 11 is separated from the limit of the engaging hole 12, and then the slider 3 is adjusted left and right, and then the force applied to the n-shaped rod 11 is cancelled, and the n-shaped rod 11 is driven to move inward by the tension of the tension spring 10 connected to the n-shaped rod 11, so that the other end of the n-shaped rod 11 is limited to other engaging holes 12.
