[0030] Embodiment 2:

[0031] like Figure 1-Figure 9 As shown, the utility model discloses a hydraulic oil filter with automatic cleaning function, and its working principle is as follows; when the device performs hydraulic oil filtering, the filter pump 3 is started, and the oil suction pipe on the filter pump 3 pumps the hydraulic oil to be filtered into the supporting filter housing 201, and the hydraulic oil slowly flows into the supporting filter housing 201 from the channel formed by the supporting bottom housing 202 and the cleaning regulating plug 106, and the filtered hydraulic oil passing through the filter screen 6 is discharged from the bottom of the supporting filter housing 201, thereby completing the filtering of the hydraulic oil.

[0032] During cleaning, the filter pump 3 does not work, and the cleaning resistance heating wire 104 is connected to the power supply through a wire. The cleaning resistance heating wire 104 begins to heat the water in the supporting stirring shell 210, the supporting tube 206, the supporting impeller shell 205, the supporting tube 1 204, and the supporting top shell 203. When the water temperature reaches a predetermined temperature, the paraffin in the chamber of the cleaning regulating plug 106 and the cleaning support frame 105 close to the cleaning reset spring 107 expands due to the heat, causing the cleaning regulating plug 106 to slide. At this time, the cleaning regulating plug 106 slides in the direction of the cleaning reset spring 107, compressing the cleaning reset spring 107, and the channel formed by the cleaning regulating plug 106 and the supporting bottom shell 202 becomes larger, and the channel formed by the cleaning regulating plug 106 and the cleaning support frame 105 is opened. At this time, the water in the supporting top shell 203 flows into the supporting filter shell 201 through the supporting bottom shell 202, and the filter screen 6 in the supporting filter shell 201 is rinsed, completing the cleaning of the filter screen 6.

[0033] During the circulation cleaning, the filter pump 3 does not work, the operator installs the support joint 209 on the bottom of the support filter housing 201, connects the cleaning resistance heating wire 104 to the power supply through the wire, and the cleaning resistance heating wire 104 starts to heat the water in the support stirring housing 210, the support tube 2 206, the support impeller housing 205, the support tube 1 204, and the support top housing 203. When the water temperature reaches the predetermined temperature, the paraffin in the chamber of the cleaning regulating plug 106 and the cleaning support frame 105 close to the cleaning reset spring 107 is heated and expanded, causing the cleaning regulating plug 106 to slide. At this time, the cleaning regulating plug 106 slides in the direction of the cleaning reset spring 107, compressing the cleaning reset spring 107, the channel formed by the cleaning regulating plug 106 and the supporting bottom shell 202 becomes larger, and the channel formed by the cleaning regulating plug 106 and the cleaning support frame 105 is opened. At this time, the water in the supporting top shell 203 flows into the supporting filter shell 201 through the supporting bottom shell 202, and the filter screen 6 in the supporting filter shell 201 is flushed. The flushing water passes through the supporting joint 209 and re-enters the supporting water tank 208, the supporting stirring shell 210, the supporting pipe 206, the supporting impeller shell 205, the supporting pipe 1 204, the supporting top shell 203, the supporting bottom shell 202, and the supporting filter shell 201 under the action of the cleaning pump 4, and circulates to flush the filter screen 6. When the water in the support tube 206 enters the support tube 1 204 through the support impeller housing 205, it drives the cleaning impeller 102 to rotate. When the cleaning impeller 102 rotates, it drives the cleaning and stirring fan blades 101 to rotate. The operator adds the cleaning agent from the support liquid adding pipe 207. The cleaning agent in the support liquid adding pipe 207 enters the support stirring housing 210 and is fully mixed with the water under the action of the rotation of the cleaning and stirring fan blades 101 to ensure the quality of cleaning.

[0034] After cleaning is completed, the cleaning resistance heating wire 104 is disconnected from the power supply. At this time, the water temperature in the device drops, the paraffin in the cleaning regulating plug 106 shrinks, and under the action of the cleaning reset spring 107, the cleaning regulating plug 106 returns to its initial position, completing the entire cleaning work.

[0035] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any form. Any simple modification or equivalent change made to the above embodiment based on the technical essence of the present invention shall fall within the protection scope of the present invention.
