Based on the above purpose, the present invention provides a vacuum oil filter device, including a filter barrel having an oil filter channel communicating up and down, a filter assembly is disposed in the oil filter channel; an air extraction unit is located on the side of the filter barrel, has A one-way valve is connected to a pipeline, and the pipeline connects a side surface and a bottom surface of the filter barrel, wherein the filter barrel bottom mask has a mounting seat to be placed in an opening of an oil storage container, and the mounting seat protrudes downward to install The platform is provided with an air-tight ring on the outer edge of the mounting platform to tightly contact the opening of the oil storage container.

Wherein, the inner wall of the filter barrel is provided with a guide wall in the shape of a funnel, and the top edge of the guide wall is provided with a stepped bearing portion to horizontally position the filter assembly. The filter assembly includes a filter paper and a partition plate, and the filter paper Both are round with the separator, and the radius of the filter paper is larger than the radius of the separator, so that the filter paper covers a plurality of holes of the separator,

Wherein, the pumping unit is provided with a pressure sensor connected to the pipeline. The pressure sensor may be a vacuum pressure gauge for detecting the vacuum pressure value inside the oil storage container.

Preferably, the filter barrel is made of stainless steel, which can avoid explosion or rupture during use.

Preferably, the user can place a second oil storage container in the oil storage space as required. In addition to keeping the oil storage container clean, the user can also directly encapsulate the second storage after filtering the oil Oil container, improve the convenience of use.

In order to clearly explain the specific implementation mode, structure and achieved effect of the new model, the explanation with the drawings is as follows:

Please refer to FIG. 1 to FIG. 3, which shows a vacuum oil filter device 100 including a filter barrel 10 having an oil filter channel communicated up and down, a filter assembly 11 is installed in the oil filter channel, an air extraction unit 12 is located One side of the filter barrel 10 and a mounting base 13 are located on the bottom surface of the filter barrel 10, so that the filter barrel 10 can use the mounting base 13 to be placed in an opening of an oil storage container 20. The inner wall of the filter barrel 10 (that is, the lower section of the oil filter channel) is provided with a guide wall 15 in the shape of a funnel, and a top edge of the guide wall 15 is provided with a stepped bearing portion 151 to position the filter horizontally The assembly 11; the suction unit 12 has a check valve 122 connected to a line 121, and the line 121 communicates with an opening 14 on the side of the filter barrel 10 and a vent hole 133 on the bottom of the mounting seat 13 to connect the suction unit 12 The oil storage container 20; In addition, a mounting platform 131 protrudes downward from the mounting base 13 of the filter barrel 10, and an airtight ring 132 is provided on the outer edge of the mounting platform 131, so that the mounting base 13 and the oil storage container The opening of 20 is tightly closed.

The filter assembly 11 includes a filter paper 111 and a partition 112. The filter paper 111 covers the partition 112 to cover a plurality of holes of the partition 112. The partition 112 is engaged with the loading portion 151 . In this embodiment, both the filter paper 111 and the separator 112 are circular, and the radius of the filter paper 111 is larger than the radius of the separator 112. By the weight of the grease to be filtered and the vacuum suction force, the filter paper 111 can be adsorbed on the partition plate 112, and no additional clamping device is needed to clamp and fix the filter paper 111.

The pipeline 121 of the air extraction unit 12 is connected to a pressure sensor 123 (such as a vacuum pressure gauge) and a vacuum pump (not shown). The pressure sensor 123 can measure the oil storage space 201 inside the oil storage container 20 Pressure value. When the pressure sensor 123 measures the pressure value of the oil storage space 201 is higher than the atmospheric pressure, the vacuum pump is turned on until the oil storage space 201 reaches a preset vacuum degree, and then the one-way valve 122 is closed to locate the diaphragm Part of the oil filtering passage and the oil storage space 201 below 112 are airtight. In addition, a quick release mechanism 124 is provided at the place where the air suction unit 12 is connected to the filter barrel 10, which can facilitate the user to achieve labor-saving and convenient effects when removing the air suction unit 12.

Under the aforementioned airtight state, the grease to be filtered above the filter paper 111 will pass through the holes of the impurity layer of the grease to be filtered, the filter paper 111 and the separator 112 due to the pressure difference between the outside and the oil storage space 201, Finally, it reaches the oil storage space 201. During the process of filtering oil, part of the oil filter channel and the oil storage space 201 under the partition plate 112 will remain airtight; in this way, the user is working on the oil filter for a long time It is not necessary to monitor the pressure value of the oil storage space 201 all the time, and it is not necessary to repeatedly start the vacuum pump to achieve the effect of convenient operation and energy saving.

In this embodiment, the filter paper 111 and the separator 112 are circular. The filter paper 111 is larger than the separator 112 so that the filter paper 111 completely covers the separator 112 without additional positioning fasteners to position the filter paper 111. The filter paper 111 can prevent impurities from falling into the filter channel from the gap and achieve the effect of one-time filtration. In other embodiments, the filter paper 111 and the separator 112 are not limited to circular, but may be square or other shapes.

In this embodiment, the airtight ring 132 is a silicone rubber layer, which increases the area of the airtight ring. When the filter device is matched with the oil storage container 20 of different sizes, the airtight effect can be achieved.

In this embodiment, the filter barrel 10 is made of stainless steel, which can avoid explosion or cracking during use.

In this embodiment, the oil storage container 20 has a faucet switch (not shown) to facilitate the user to bottle the filtered oil in the oil storage space 201; in addition, the user can place other diameters as required A container smaller than the opening of the oil storage container 20, such as household pots, bottles, etc., is placed in the oil storage space 201 as the second oil storage container 21 and is aligned with the opening below the guide wall 15 except that it can maintain the oil storage In addition to the cleaning of the space 201, it is also convenient for the user to clean the oil storage space 201 after using the vacuum oil filter device 100, and can directly encapsulate the filtered oil stored in the second oil storage container 21.
