DETAILED DESCRIPTION

[0017] The technical solutions in the embodiments of the patent will be clearly and completely described below with reference to the drawings in the embodiments of the patent. Obviously, the described embodiments are only part of the embodiments of the patent, not all the embodiments. Based on the embodiments in the patent, all other embodiments obtained by those of ordinary skill in the art without creative labor are within the scope of protection of the patent.

[0018] Please refer to Figures 1-3This patent provides a technical solution: a high-efficiency water-absorbing gasoline filter element, including an outer cylinder 1, a top cover 2 integrally formed on the top of the outer cylinder 1, an oil inlet pipe 3 embedded in the middle of the top of the top cover 2, water-absorbing cotton 4 fixedly installed at the bottom of the top cover 2, the water-absorbing cotton 4 having curved holes 5, a fixing ring 6 integrally formed on the inner side wall of the outer cylinder 1, a filter cloth 7 provided on the inner side wall of the fixing ring 6, an inner cylinder 8 provided inside the outer cylinder 1, water-absorbing resin particles provided inside the inner cylinder 8, an oil outlet pipe 9 provided at the bottom front of the inner cylinder 8, a connecting ring 10 integrally formed on the upper end of the outer side wall of the inner cylinder 8, and a rubber ring 11 fixedly installed on the top of the connecting ring 10;

[0019] like Figure 1 As shown, the absorbent cotton 4 is provided with a large number of curved holes 5. The multiple curved holes 5 are evenly distributed on the absorbent cotton 4, which facilitates the passage of gasoline.

[0020] The outer cylinder 1 has rectangular holes 12 at both ends of its side wall. The outer side wall of the outer cylinder 1 is threaded and screwed with an internal threaded ring 13. A riser 14 is provided outside the internal threaded ring 13. A circular groove 15 is provided on the upper side of the inner side wall of the riser 14. A circular ring 16 is rotatably installed in the circular groove 15. The shape and size of the circular ring 16 match the internal shape and size of the circular groove 15. The inner side wall of the circular ring 16 is integrally formed on the bottom side of the outer side wall of the internal threaded ring 13. The inner side wall of the riser 14 has sliding holes 17 at both ends of its inner side wall. A slide rod 18 is slidably installed on the inner side wall of the sliding hole 17. The inner end of the slide rod 18 extends into the outer cylinder 1 through the rectangular hole 12. The top of the side wall of the slide rod 18 is tightly fitted to the bottom of the connecting ring 10. The top of the rubber ring 11 is tightly fitted to the bottom of the fixing ring 6.

[0021] The ring 16 can only rotate within the ring groove 15 and cannot move in other directions within the ring groove 15. It is used to make the internal threaded ring 13 and the riser 14 rotate relative to each other.

[0022] By tightening the internal threaded ring 13, an upward pressure is applied to the riser 14 and the slide bar 18, thereby causing the top of the rubber ring 11 to fit tightly against the bottom of the fixing ring 6.

[0023] Specifically, the bottom left and right sides of the connecting ring 10 are provided with positioning grooves, and the top of the side wall of the slide rod 18 is integrally formed with a positioning post 19, which is inserted into the positioning groove.

[0024] By setting the positioning pin 19 to be inserted into the positioning slot, it can be avoided Figure 1 In this state, the slide bar 18 moves left and right to disengage from the connecting ring 10.

[0025] Specifically, the sliding hole 17 is a square hole, and the sliding rod 18 is a square rod that matches the sliding hole 17.

[0026] Specifically, the bottom of the oil inlet pipe 3 is integrally formed with a diversion pipe 20, and the inside of the top cover 2 is provided with a pipe hole that matches the diversion pipe 20. The diversion pipe 20 is installed in the pipe hole.

[0027] The splitter pipe 20 can split the gasoline flowing down from the oil inlet pipe 3, so that the gasoline falls evenly onto the absorbent cotton 4.

[0028] Specifically, the riser 14 includes a first half-pipe 21 and a second half-pipe 22, with the two ends of the first half-pipe 21 and the second half-pipe 22 fixed together.

[0029] like Figure 3 As shown, by dividing the riser 14 into a first half-pipe 21 and a second half-pipe 22, the annular groove 15 on the inner wall of the riser 13 can be divided into two parts, which makes it easier to fit the annular groove 15 onto the outside of the annular ring 16 in the early stage.

[0030] Specifically, the inner bottom of the inner cylinder 8 is provided with a mesh body 23, the pore size of the mesh body 23 is smaller than the particle size of the water-absorbing resin particles, and the water-absorbing resin particles are located on the mesh body 23.

[0031] By setting the mesh 23, water-absorbing resin particles can be prevented from entering the oil outlet pipe 9.

[0032] Working principle: Gasoline enters the absorbent cotton 4 through the inlet pipe 3, where the water in the gasoline is absorbed by the absorbent cotton 4. The gasoline then enters the inner cylinder 8 through the filter cloth 7, where impurities in the gasoline are trapped by the filter cloth 7. The gasoline is then further absorbed by the absorbent resin particles and finally flows out through the outlet pipe 9.

[0033] When disassembling the outer cylinder 1 and the inner cylinder 8, rotate the inner threaded ring 13 so that it drives the riser 14 downward through the ring 16 until the positioning pin 19 disengages from the positioning groove at the bottom of the connecting ring 10. Then, manipulate the two sliding rods 18 to move them away from each other, and then move the inner cylinder 8 downward to disengage from the outer cylinder 1.

[0034] The technical solutions of this patent embodiment will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only a part of the embodiments of this patent, and not all of them. Based on the embodiments of this patent, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this patent.
