[0027] like Figure 1-Figure 4 As shown, an integrated all-plastic filter provided by an embodiment of the utility model includes a filter tank 1, and a locking threaded ring 2 is connected to the outside of the filter tank 1, a filter element 19 is arranged inside the filter tank 1, and the filter element 19 is a detachable structure, and a preset electronic component 12 and a drain valve 5 are arranged at the bottom area of ​​the surface of the filter tank 1, and the preset electronic component 12 is a water level sensor or a heater. The above technical features are all mature existing technologies, which are technical solutions that are not difficult to obtain or think of by those skilled in the art, and those skilled in the art can make corresponding adjustments and selections based on the above technical solutions;

[0028] The inner side of the locking thread ring 2 is connected with the filter seat housing 3. The locking thread ring 2 is made of engineering plastics and is threadedly connected to the filter seat housing 3 to lock the filter tank 1 and the filter seat housing 3 together.

[0029] The upper and lower sides of the outer side of the filter housing 3 are respectively connected with an oil outlet pipe joint 8 and an oil inlet pipe joint 9, a pump chamber is arranged inside the filter housing 3, and an electric pump bracket 15 is arranged inside the pump chamber, an electric pump 13 is installed outside the electric pump bracket 15, an electric pump end cover 4 is detachably connected to the outer side of the filter housing 3 near the electric pump 13, and an electric pump control board 18 is installed inside the electric pump end cover 4, the electric pump control board 18 is electrically connected to the electric pump 13 through a wire, the electric pump 13 of the filter belt of the present application is generally an auxiliary oil pumping function, the control mode of the electric pump 13 can be realized by adjusting the electric pump control board 18 according to the specific requirements of the actual working conditions, generally it starts after each power-on and stops after a specified time;

[0030] The interior of the filter seat housing 3 is provided with an oil outlet cavity 23, an oil pumping cavity 24 and a filter element clean oil cavity 25 in sequence from high to low, and a one-way valve 22 is installed inside the oil outlet cavity 23. The one-way valve 22 is an umbrella-shaped structure, and the material of the one-way valve 22 is rubber. An oil outlet 20 is provided inside the oil outlet cavity 23, and the oil outlet 20 is connected to the oil outlet pipe joint 8. A bypass hole is provided between the oil pumping cavity 24 and the oil outlet cavity 23, and a pressure relief valve 21 is installed inside the bypass hole. The pressure relief valve 21 is a spring ball valve, which is assembled in the bypass hole between the oil pumping cavity 24 and the oil outlet cavity 23 of the filter seat housing 3, and the assembly method is interference fit and coated with sealant.

[0031] The filter tank 1, the filter seat housing 3, the oil outlet pipe joint 8 and the oil inlet pipe joint 9 are all components made of engineering plastics. By making the above components all of engineering plastics, the lightweight degree of the integrated filter can be greatly improved.

[0032] In one embodiment of the utility model, when it is necessary to assist the oil pumping operation with the aid of the electric pump 13, the electric pump 13 can be turned on through the electric pump control panel 18, and the electric pump 13 works and generates negative pressure, so that the fluid medium is sucked into the filter through the oil inlet under the action of the negative pressure of the electric pump 13, and the fluid medium will enter the dirty oil area of ​​the filter tank 1 along the inner wall of the filter tank 1, and after the fluid medium is filtered by the filter element 19, the clean fluid medium enters the pump oil cavity 24 through the filter element clean oil cavity 25, and when the fluid medium reaches the oil outlet 20 through the electric pump 13, although the oil outlet 20 is connected with the oil outlet cavity 21, due to the one-way valve 22 provided inside the oil outlet cavity 21, the fluid medium can only flow into the downstream device through the oil outlet 20, thereby quickly removing the residual gas in the filter or the oil pipe, and assisting the downstream device to quickly build pressure;

[0033] During the operation of the electric pump 13, when the pressure of the oil outlet cavity 23 exceeds the set pressure value, the pressure relief valve 21 opens. Since the pressure relief valve 21 connects the oil outlet cavity 23 and the oil pump cavity 24, part of the fluid medium can flow back to the oil pump cavity 24, thereby ensuring that the output pressure of the oil outlet cavity 24 is always maintained within the set value range;

[0034] When the electric pump 13 stops working, the filter still has a normal filtering function. At this time, the fluid medium is sucked into the filter through the oil inlet under the negative pressure of the oil pump of the whole system. When the fluid medium passes through the filter element 19, the particulate impurities and water in the fluid medium are filtered by the filter element. The clean fluid medium enters the oil outlet 20 through the one-way valve 21 in the oil outlet cavity 23 and finally flows into the downstream device.

[0035] Understandably, Figure 2 and Figure 3 The first fluid flow direction and the second fluid flow direction in the middle finger refer to the flow direction of the fluid medium when the electric pump is working and the flow direction of the fluid medium when the electric pump stops working, respectively.

[0036] Preferably, a mounting panel 7 is connected to the outer side of the filter seat housing 3 , and a plurality of mounting holes 6 are formed on the surface of the mounting panel 7 , and metal sleeves are press-fitted inside the mounting holes 6 .

[0037] Preferably, a first O-ring 14 is provided on the outside of the electric pump 13, a second O-ring 16 is provided between the electric pump 13 and the filter seat housing 3, and a sealing ring 17 is provided at the connection between the electric pump end cover 4 and the filter seat housing 3. The oil suction area and the oil discharge area of ​​the electric pump 13 are separated by the first O-ring 14, and external sealing is achieved by the second O-ring 16. By providing the sealing ring 17, dust and water can be prevented from entering the interior of the filter seat housing 3.

[0038] Preferably, a positioning groove is provided on the outer side of the locking thread ring 2, and a positioning boss 10 is provided on the surface of the filter tank 1, and the number of the positioning groove and the positioning boss 10 are both two, so that when the locking thread ring 2 is disassembled, the locking thread ring 2 can be prevented from falling directly.

[0039] Preferably, a third O-ring is arranged between the filter tank 1 and the filter seat housing 3, a fourth O-ring is arranged at the connection between the filter element 19 and the filter seat housing 3, and a fifth O-ring is arranged between the filter element 19 and the filter tank 1, thereby greatly improving the sealing performance between the filter tank 1 and the filter seat housing 3, between the filter element 19 and the filter seat housing 3, and between the filter element 19 and the filter tank 1.

[0040] Preferably, a reinforcing rib 11 is provided at the inner bottom of the filter tank 1, and the filter element 19 is limited between the reinforcing rib 11 and the filter seat housing 3, so that the installation state of the filter element 19 inside the filter is not only stable but also reliably sealed.
