A gasoline filter 100 further comprising: a hydraulic pressure detection feedback mechanism 50. The hydraulic pressure detection feedback mechanism 50 includes: built-in cylinder 51, piston plate 52, sliding support assembly 53, buffer connection assembly 54, roller 55, activation key switch 56 and indicator light 57. The filter element 40 is fixedly mounted to the inner right end of the cylindrical outer case 10. The inner tube 51 is fitted horizontally to an intermediate position of the filter element 40 and is fixedly connected to the cylindrical outer case 10. The left end of the built-in cylinder 51 is open. The piston plate 52 is slidably disposed at the left end opening of the inner cylinder 51. A sliding support assembly 53 is connected between the piston plate 52 and the inner wall of the right end of the inner cylinder 51. The roller 55 is connected to the sliding end of the sliding support member 53 by a buffer connection member 54. While the roller 55 is attached at the inner wall of the inner cylinder 51. The actuating key switches 56 are installed at a plurality of inner walls of the inner cylinder 51 at equal intervals in the lateral direction, and the actuating key switches 56 are located on the rolling track of the wheel 55. The indicator lamp 57 is provided in plurality, and the indicator lamp 57 is electrically connected to the start key switch 56 correspondingly. While indicator lights 57 are mounted in a human monitorable location.

The key body of the activation key switch 56 is a spheroid that facilitates the squeezing of the wheel 55.

The hydraulic pressure detection feedback mechanism 50 further includes: a resilient sealing rubber ring 58. An elastomeric sealing rubber ring 58 is connected between the piston plate 52 and the opening of the inner barrel 51. The elastomeric sealing gasket 58 prevents gasoline from entering the inner barrel 51 and contaminating the internal components.

The sliding support assembly 53 includes: a connecting sleeve 531, a sliding rod 532, a connecting block 533 and a supporting spring 534. The connection sleeve 531 is fixedly connected to an inner middle position of the inner cylinder 51. The sliding bar 532 is inserted in the connecting sleeve 531 in a horizontal sliding way. Piston plate 52 is fittingly connected to the left end of slide bar 532. The connecting block 533 is fixedly connected to the right end of the sliding bar 532.

When the filter element 40 in the cylindrical outer shell 10 is used for a long time and the flow blocking effect is deteriorated, the hydraulic pressure of the gasoline entering the cylindrical outer shell 10 is gradually increased because the gasoline cannot be effectively discharged. When the hydraulic pressure rises inside the outer cylindrical housing 10, it acts on the piston plate 52 at the opening of the inner cylinder 51. The piston plate 52 is slid along the connection sleeve 531 by means of the slide bar 532 to compress the supporting spring 534. In the process, the telescopic connecting rod 541 moves along with the sliding rod 532, so that the telescopic connecting rod 541 drives the roller 55 to roll along the inner wall of the inner cylinder 51. And the greater the hydraulic pressure to which the piston plate 52 is subjected, the longer the distance that its interlocking rollers 55 move. And because the telescopic link 541 has telescopic property, the roller 55 is conveniently rolled and pressed onto the start key switch 56. The actuation push switches 56 thus distributed on the movement path of the scroll wheel 55 are pressed one by one to activate the corresponding indicator lights 57. The higher the position of the indicator light 57 is, the poorer the filter effect is, so that the user can replace the filter in time according to the situation.

A gasoline filter 100 further comprising: and a pressing mechanism 60. The pressurizing mechanism 60 includes: the device comprises an electric telescopic rod 61, a trigger switch group 62, a strip-shaped sliding groove 63, a pressurizing ring 64, a linkage assembly 65 and an auxiliary closing assembly 66. The electric telescopic rod 61 is fixedly connected to the left end of the sliding rod 532. The piston plate 52 is fixedly connected to the telescopic end of the electric telescopic rod 61. The trigger switch group 62 is provided at the right-end inner wall of the built-in cylinder 51. The trigger switch group 62 is electrically connected to the electric telescopic rod 61.

The pressurizing ring 64 is connected to the strip-shaped chute 63 in a sliding manner, and the inner ring opening of the pressurizing ring 64 is opposite to the oil inlet check valve 20. A linkage assembly 65 is cooperatively coupled between press ring 64 and piston plate 52. A secondary closure assembly 66 is provided at the press ring 64.

The trigger switch group 62 includes: a small support tube 621, a first connection spring 622, and a pressure sensing switch 623. A small support pipe 621 is fixedly attached to the right end inner wall of the inner cylinder 51. The first connecting spring 622 is connected to the inside of the small support tube 621. The pressure sensing switch 623 protrudes outside the inner cylinder 51. While the pressure sensing switch 623 is connected to the first connecting spring 622.

The connection ring 652 is provided at the left end outside of the built-in cartridge 51. The connecting rod 653 is horizontally fixedly connected to the connecting ring 652. The connecting rod 653 is slidably inserted into the sidewall of the inner cylinder 51. The fixed pulley 654 is fixedly mounted to the right end of the bar chute 63. The steel wire 651 is connected between the pressing ring 64 and the connection ring 652. The steel wire 651 is wound around the fixed pulley 654. The second connecting spring 656 is connected between the pressing ring 64 and the bar-shaped chute 63.

When the flow effect of the filter cartridge 40 is deteriorated, the hydraulic pressure inside the cylindrical outer housing 10 gradually rises, causing the piston plate 52 to push the sliding rod 532 to slide and compress the supporting spring 534 to the limit position, the connecting block 533 at the end of the sliding rod 532 just abuts against the small supporting pipe 621. And presses the pressure sensitive switch 623 into the small this time tube 621. Thus, the pressure sensing switch 623 triggers the electric telescopic rod 61 to perform telescopic motion. When the electric telescopic rod 61 is extended, it drives the piston plate 52 to slide and extrude into the cylindrical outer shell 10, so as to pressurize the gasoline inside the cylindrical outer shell 10. While the piston plate 52 traverses away from the inner barrel 51, it pushes the connecting ring 652 in a direction away from the inner barrel 51. The connection ring 652 thus pulls the pressing ring 64 by the wire 651. The pressing ring 64 is slidably pressed against the filter cartridge 40 along the strip-shaped slide groove 63. Thereby facilitating the gasoline to be pressurized to pass through the filter element 40 and avoiding influencing the use of the gasoline.

The secondary closure assembly 66 includes: closing the rotating plate 661 and the elastic connecting string 662. The closing flap 661 is coupled in pairs to the inner ring position of the press ring 64 by a resilient hinge. And the pair of closing rotating plates 661 can be assembled as a complete circular plate to close the middle portion of the pressurizing ring 64. An elastic connection cord 662 is connected between the closing flap 661 and the inner wall of the cylindrical outer case 10.

When the pressurizing ring 64 is slid toward the filter cartridge 40 in conjunction with the extension of the electric telescopic rod 61, the connection restriction due to the elastic connection cord 662. Therefore, the closing rotating plate 661 located at the middle position of the pressing ring 64 rotates to the middle position of the pressing ring 64 by the reverse pulling action of the elastic connecting string 662 to perform the splicing oscillation. This facilitates the compression ring 64 as a complete plate to compress the gasoline.

The splicing end of the closed rotating plate 661 is provided with an engagement slot 6611. When the pair of closed rotating plates 661 are rotatably spliced together, the splicing ends are engaged and spliced together.
