[0026] The following is a further detailed description of the specific implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but are not intended to limit the scope of the present invention.

[0027] See also Figure 1-6 As shown, the utility model provides a filter cartridge for the top water injection port of a sprinkler truck, comprising a filter cartridge body 1 and a plurality of funnel-type screens 4, the outer wall of the filter cartridge body 1 is penetrated with a plurality of filter holes 11, a bottom cover 2 is movably connected to the bottom of the filter cartridge body 1, a plurality of fixed seats 3 are fixedly connected to the inner wall of the filter cartridge body 1 at equal intervals above and below, the plurality of funnel-type screens 4 are movably connected to the inside of the plurality of fixed seats 3, a sedimentation trough 44 is fixedly connected to the bottom of the funnel-type screen 4, a plurality of sieve holes 45 are penetrated on the surfaces of the funnel-type screen 4 and the sedimentation trough 44, and the diameters of the sieve holes 45 on the surface of the funnel-type screen 4 become smaller from top to bottom.

[0028] The utility model installs the filter cartridge body 1 at the water injection port, and can effectively intercept large particles of impurities, foreign matter or sediment in the water during the water injection process, blocking the path of these impurities entering the water tank of the sprinkler truck, and avoiding the occurrence of nozzle blockage.

[0029] When water is injected, water flows in through the opening of the filter cartridge body 1, and then passes through the multiple groups of funnel-type screens 4 with diameters of sieve holes 45 that decrease from large to small to filter impurities. This step-by-step filtering method makes the filtering effect better and avoids the clogging of the sieve holes 45. The funnel structure of the funnel-type screen 4 increases the filtering area, and the filtered impurities will slide down with the funnel-type screen 4 and be deposited in the sedimentation tank 44, reducing the situation where impurities adhere to the surface of the funnel-type screen 4 and enhancing the filtering effect.

[0030] Furthermore, the bottom cover 2 includes a fixing buckle 21, a funnel filter 22 and a collecting tank 23. A threaded buckle 12 is provided on the outer wall of the filter cartridge body 1 and below the filter hole 11. The fixing buckle 21 is threadedly sleeved on the outer side of the threaded buckle 12. The funnel filter 22 is fixedly connected to the lower surface of the fixing buckle 21, and the collecting tank 23 is fixedly connected below the funnel filter 22. In other words, the fixing buckle 21 and the threaded buckle 12 are threadedly connected, which is convenient for quick disassembly when cleaning the bottom cover 2. Impurities filtered by the funnel filter 22 will be deposited inside the collecting tank 23 and will not accumulate on the filtering surface of the funnel filter 22, thereby maintaining the clean state and high-efficiency filtering ability of the funnel filter 22.

[0031] Furthermore, the surfaces of the funnel-type filter 22 and the collection tank 23 are penetrated with a plurality of filter holes 231, and the diameter of the filter holes 231 is the same as the diameter of the filter holes 11; during the water injection process, the water will pass through the funnel-type screen 4 with multiple groups of screen holes 45 with diameters changing from large to small to filter impurities, and finally flow out from the filter holes 231. When the water injection volume is too large, part of the water can also flow out directly after being filtered through the filter holes 11, providing more flow paths for the water.

[0032] Furthermore, a sealing ring 24 is sandwiched between the fixing buckle 21 and the filter cartridge body 1, and the sealing ring 24 is attached to the lower surface of the filter cartridge body 1; the sealing ring 24 can seal between the fixing buckle 21 and the filter cartridge body 1 to prevent water from seeping out from the gap.

[0033] Further, the fixing seat 3 includes a center ring 31, which is fixedly connected to the inner side wall of the filter cartridge body 1, and the surface of the center ring 31 is provided with four groups of through grooves 311 at equal intervals, and a slide groove 312 is provided between each two adjacent groups of through grooves 311, and a limit groove 313 is provided on the bottom surface of the slide groove 312, and a fixing ring 41 is fixedly connected to the upper surface of the funnel-type screen 4, and four groups of limit blocks 42 are fixedly connected to the outer side of the fixing ring 41 at equal intervals, and the four groups of limit blocks 42 are respectively inserted into the limit grooves 313 at corresponding positions; when installing the funnel-type screen 4, the limit blocks 42 can be inserted from the through grooves 311 and slid into the slide grooves 312, and then the position of the fixing ring 41 is adjusted to ensure that the limit blocks 42 are inserted into the limit grooves 313, thereby completing the fixing of the funnel-type screen 4. This design allows the funnel-type screen 4 to be easily fixed on the center ring 31 and can be easily disassembled.

[0034] Furthermore, the upper and lower surfaces of the center ring 31 are fixedly connected with a guide ring 32, and the inner side of the guide ring 32 is inclined; the function of the guide ring 32 is that impurities in the water body will not adhere to the surface of the guide ring 32, reducing the cleaning dead corners on the filter cartridge body 1.

[0035] Furthermore, ear plates 43 are fixedly connected to both sides of the upper surface of the fixing ring 41; holes are provided on the sides of the ear plates 43, and the staff can use wires to hook the ear plates 43, so as to more conveniently manipulate the ear plates 43, or use other tools to fix and clamp the ear plates 43, and can also manipulate the ear plates 43 to achieve the purpose of adjusting the fixing ring 41, making the adjustment of the fixing ring 41 more flexible and convenient.

[0036] Working principle: Place the filter cartridge body 1 at the water inlet. During the water injection process, water will flow in from the upper opening of the filter cartridge body 1, and pass through the funnel-shaped screen 4 with multiple groups of screen holes 45 with diameters decreasing from large to small to filter impurities, and finally flow into the water tank through the filter hole 231 of the funnel-shaped filter 22 or the filter hole 11 opened on the outer wall of the filter cartridge body 1.

[0037] The staff needs to regularly disassemble and clean the filter cartridge body 1, specifically: first manually rotate the fixing buckle 21 to disengage it from the threaded buckle 12, and then the bottom cover 2 can be removed. Then, use a wire or other tool to hook and clamp the ear plate 43, pull the ear plate 43 upward to disengage the limit block 42 from the limit groove 313, and then apply a rotational force to the ear plate 43, so that the fixing ring 41 drives the limit block 42 to rotate inside the slide groove 312 until the limit block 42 moves to the through groove 311, and the funnel-type screen 4 can be disassembled.

[0038] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. It should be pointed out that a person skilled in the art can make several improvements and modifications without departing from the technical principle of the present invention, and these improvements and modifications should also be regarded as within the protection scope of the present invention.
