After passing through the left filter screen 104d, the control oil will be filtered again through the filter element 104c and the right filter screen 104d, and then discharged from the outlet tube 104b.

[0040] Further, such as Figure 7In the figure, the elastic component 105 includes an extrusion tube 105a adapted to the outer wall of the outlet tube 104b, and an adjustment plate 105b sliding on the extrusion tube 105a, and also includes a No. 1 spring 105c fixed between the extrusion tube 105a and the adjustment plate 105b, and also includes a screw rod 105d movably connected to the adjustment plate 105b, the screw rod 105d is connected to the containing box 101a, and the screw rod 105d is rotatably connected to the protruding end 101b of the containing box 101a.

Because the seesaw assembly 202 is in an inclined state in the initial state, the round block 202b on one side of the seesaw assembly 202 will drive the connecting rod 102e and the blocking block 102d to block the sealing ring 102c through the guide tube 103d, and the other side is opposite, so that one side of the telescopic assembly 103 is in an open state and the other side is in a closed state.

[0043] Further, such as Fig. 9 , 10In the figure, the delay component 203 includes a round tube 203a fixed to the top of the guide component 102 corresponding to the right side of the limit component 201, the round tube 203a is fixed to the top of the convex plate 102a in the guide component 102 corresponding to the right side of the elliptical disk 201a, the outer wall of the round tube 203a is provided with a transverse groove 203b, and a slide bar 203c sliding in the corresponding transverse groove 203b of the round tube 203a, and also includes a No. 2 spring 203d fixed between the round tube 203a and the slide bar 203c, and also includes a curved rod 203e arranged on both sides of the slide bar 203c, and the curved rod 203e is provided with a groove 203f at the corresponding position of the slide bar 203c. The right side of the slot 203f is an opening, the curved rod 203e is connected to the telescopic component 103, the curved rod 203e is fixed on the right side of the telescopic end 103e corresponding to the guide tube 103d in the telescopic component 103, the sliding rod 203c is connected to the limit component 201, the sliding rod 203c is fixed to the limit rod 201c in the limit component 201, when the curved rod 203e on one side moves to the right, the sliding rod 203c located in the slot 203f of the curved rod 203e on one side will be driven to squeeze the No. 2 spring 203d, and the other side of the sliding rod 203c will move to the right from the slot 203f of the curved rod 203e on the other side.

[0044] Further, such as Fig.11 , 12 In the figure, the switching component 204 includes a device shell 204a fixed on the top of the guide component 102 corresponding to the left side of the limit component 201, the device shell 204a is fixed on the top of the convex plate 102a in the guide component 102 corresponding to the left side of the elliptical disk 201a, and a protrusion 204b sliding on the right side of the device shell 204a, and also includes a No. 3 spring 204c fixed between the device shell 204a and the protrusion 204b, and also includes a roller 204d adapted to the end of the protrusion 204b, the roller 204d is connected to the limit component 201, and the roller 204d is connected to the elliptical disk 201a in the limit component 201.

[0045] When in use, by connecting the return pipe of the engine control oil to the three-way pipe 102b, the control oil can be guided to the telescopic component 103 opened on one side through the three-way pipe 102b, and the control oil is guided to the guide pipe 103d and the filter pipe 104a in the telescopic component 103, and after being filtered by the filter element 104c and the filter screen 104d, it is guided to the squeeze pipe 105a through the outlet pipe 104b, and then guided to the inside of the containing box 101a through the squeeze pipe 105a. In this process, if the filter component 104 on the telescopic component 103 opened on one side is clogged, the thrust of the control oil can squeeze the filter component 104 The elastic component 105 is squeezed, thereby the service life of the filter component 104 can be observed. In this process, the filter component 104 will also drive the guide tube 103d in the telescopic component 103. The end of the guide tube 103d connected to the telescopic component 103 will drive the curved rod 203e and the sliding rod 203c. The sliding rod 203c will squeeze the second spring 203d. At the same time, the sliding rod 203c will drive the limit rod 201c to gradually disengage from the cross groove 201b. When the limit rod 201c is completely separated from the cross groove 201b, the elliptical disk 201a can be separated from the limit, and the control oil at this time can push the blocking block 102d on the other side to disengage from the sealing ring. 102c, thereby the blocking block 102d will drive the connecting rod 102e, the guide tube 103d, and the round block 202b to move, and the round block 202b can drive the central plate 202a and the elliptical disk 201a to rotate, thereby, the round block 202b on the other side will drive the guide tube 103d, the connecting rod 102e, and the blocking block 102d on the other side to block the sealing ring 102c here, during this process, the rotation of the elliptical disk 201a will drive the roller 204d to squeeze the protrusion 204b, when the roller 204d passes the protrusion 204b, the protrusion 204b will squeeze the third spring 204c, after the roller 204d passes the third spring 204c will drive the protrusion 204b to reset, and the roller 204d can be temporarily reset again. Therefore, after switching the filter channel, the filter component 104 at the blocked position will lose the thrust of the control oil, so that the No. 1 spring 105c in the elastic component 105 will drive the extrusion tube 105a, the filter component 104, and the telescopic component 103 to reset. At this time, the guide tube 103d in the telescopic component 103 will also drive the delay component 203 to reset, so that the limit rod 201c pulled out by the delay component 203 will be inserted into the hole on the other side of the cross groove 201b, thereby completing the effect of automatically switching the filter channel.

[0046] In summary, the pressure can be transmitted to the elastic component 105 through the filter component 104, thereby having the effect of detecting the filtering life of the filter component 104, and during the movement of the filter component 104, the telescopic component 103 can be driven to trigger the delay component 203, the limit component 201, the seesaw component 202, the switching component 204, and the guide component 102, thereby completing the automatic switching function of the filter component 104, and having the function of filtering and controlling the oil when replacing the filter component 104.

[0047] It should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention rather than to limit it. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present invention may be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present invention, which should all be included in the scope of the claims of the present invention.
