Description

Technical Field

[0001] The utility model relates to the technical field of oil filters, in particular to an automobile oil filter. Background Art

[0002] The automobile oil filter removes most of the harmful impurities in the oil by installing a filter element inside, thereby keeping the oil clean so that various parts in the engine can be lubricated by clean oil during operation, thereby reducing the wear of various parts.

[0003] After long-term use, impurities in the existing oil filter will gradually accumulate and clog the filter element, thereby hindering the flow of oil and making it difficult for the oil to flow to various parts in the engine. Therefore, in order to ensure that various parts of the engine can be lubricated by the oil, the driver will replace the filter element every time the car is driven for a period of time.

[0004] Normally, drivers judge whether to replace the filter element based on the length of time the car has been used or the distance the car has traveled. However, due to different driving habits and different road conditions, when the car has traveled a predetermined distance or time, the filter element may not be clogged by impurities in the oil, so there is no need to replace the filter element temporarily. However, the driver cannot accurately judge whether the filter element is clogged at this time, so when the driver replaces the filter element according to the above judgment criteria, the filter element may be replaced prematurely, resulting in unnecessary waste of materials.

[0027] The following description is used to disclose the utility model so that those skilled in the art can implement the utility model. The preferred embodiments described below are only examples, and those skilled in the art can think of other obvious variations. The basic principles of the utility model defined in the following description can be applied to other embodiments, variations, improvements, equivalents, and other technical solutions that do not deviate from the spirit and scope of the utility model.

[0028] Those skilled in the art should understand that, in the disclosure of the present invention, the terms "longitudinal", "lateral", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside" and the like indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, which are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, the above terms should not be understood as limiting the present invention.

[0029] It is to be understood that the term "one" should be understood as "at least one" or "one or more", that is, in one embodiment, the number of an element may be one, while in another embodiment, the number of the element may be multiple, and the term "one" should not be understood as a limitation on the quantity.

[0030] refer to Figures 1 to 6 An automobile oil filter according to a preferred embodiment of the utility model will be described in detail below. The automobile oil filter includes a filter body 10, a filter element 20 and a detection component 30.

[0031] The filter body 10 has a detection channel 101, and the detection channel 101 is connected to the interior of the filter body 10. The filter element 20 is arranged inside the filter body 10 to filter out impurities in the engine oil. The detection component 30 is arranged in the detection channel 101 of the filter body 10, and the detection component 30 is used to detect whether the filter element 20 is blocked by impurities in the engine oil.

[0032] Preferably, an inner wall forming the detection channel 101 forms a protrusion at the channel openings on both sides of the detection channel 101 , respectively, and the protrusion is used to prevent the detection component 30 from detaching from the detection channel 101 .

[0033] In one embodiment, the detection component 30 is configured as a movable plug, which is driven and movably installed in the detection channel 101. When the filter element 20 is completely blocked, the oil entering the filter body 10 cannot be discharged, so that the internal pressure of the filter body 10 gradually increases, and then the movable plug gradually moves along the direction of extending out of the detection channel 101. Therefore, a marking point can be set on the movable plug to inform the driver that the current filter element 20 is completely blocked. Therefore, when the marking point on the movable plug can be observed by the driver, it means that the blockage of the filter element 20 is serious and a new filter element 20 needs to be replaced. When the driver cannot observe the marking point, it means that the filter element 20 at this time has not yet reached the degree of being blocked by impurities to the point of needing to be replaced.

[0034] As an example, the detection assembly 30 includes a display block 31, a transmission assembly 32 and a movable block 33, wherein the display block 31 is arranged to be maintained at a position relative to the movable block 33, and the display block 31 is mounted on one end of the transmission assembly 32. The movable block 33 is mounted on the other end of the transmission assembly 32, and the movable block 33 is arranged to move in the detection channel 101 under external force, and drives the display block 31 and the transmission assembly 32 to move along the moving direction of the movable block 33.

[0035] It is understandable to those skilled in the art that when the movable block 33 is subjected to pressure from inside the filter body 10 , the movable block 33 will move and drive the display block 31 and the transmission assembly 32 to move.

[0036] It should be noted that the display block 31 is used to display information on whether the filter element 20 is blocked, and allows the driver to determine whether to replace the new filter element 20 based on the information displayed on the display block 31, so a marking point can be set on the display block 31, wherein the appearance of the marking point indicates that the filter element 20 is seriously blocked, and the hiding of the marking point indicates that the filter element 20 is not blocked to the point where it needs to be replaced. Specifically, when the display block 31 moves along the inner wall forming the detection channel 101 so that the marking point is not in the detection channel 101, the marking point is exposed, and the marking point can be observed by the driver at this time. When the display block 31 moves along the inner wall forming the detection channel 101 and the marking point is in the detection channel 101, the marking point is hidden in the detection channel 101, and the driver cannot see the marking point at this time.

[0037] That is to say, when the driver observes the marking point on the display block 31, it means that the filter 20 is completely blocked and needs to be replaced with a new filter 20. If the driver does not observe the marking point, it means that the filter 20 is not blocked seriously and does not need to be replaced with a new filter 20 for the time being.

[0038] It should be added that, under normal circumstances when the filter element 20 is not blocked, the display block 31 is stored in the detection channel 101, so the driver cannot observe the marking point on the display block 31. Therefore, the driver will think that the filter element 20 is not blocked and will not replace the filter element 20 with a new one.

[0039] In this way, when the filter element 20 is clogged by impurities in the oil, the oil in the filter body 10 will gradually increase because it cannot be discharged from the outlet 1203, thereby gradually increasing the pressure inside the filter body 10, and thus the movable block 33 is pressed to move. The movable block 33 drives the transmission assembly 32 to move, and the display block 31 is also driven, and the display block 31 moves in the detection channel 101 in the same direction as the moving direction of the movable block 33 until the marking point on the display block 31 can be observed by the driver, at which time the driver can replace the filter element 20 with a new one.

[0040] It is worth mentioning that when the driver observes the marking point on the display block 31, the driver can indirectly judge the impurity content of the engine oil inside the car based on the current driving distance or usage time of the car.

[0041] Preferably, one end of the display block 31 extends in a radial direction to form a step 311, and the step 311 acts on the protrusion so that the display block 31 moves along the inner wall forming the detection channel 101 without separating from the detection channel 101, thereby preventing the display block 31 from separating from the detection channel 101 and causing detection failure.

[0042] Preferably, the transmission assembly 32 includes a first magnetic member 321 and a second magnetic member 322. Preferably, the first magnetic member 321 and the second magnetic member 322 are both implemented as a magnet, and the first magnetic member 321 and the second magnetic member 322 are relatively arranged to generate a repulsive force, wherein the first magnetic member 321 is installed on the movable block 33. The second magnetic member 322 is installed on the display block 31. When the movable block 33 drives the first magnetic member 321 to move, the second magnetic member 322 moves due to the repulsive force and drives the display block 31 to move.

[0043] Further preferably, the detection assembly 30 further includes a reset member 34. Further preferably, the reset member 34 is implemented to include a spring, one end of the spring is connected to the first magnetic member 321, and the other end of the spring is connected to the second magnetic member 322.

[0044] It should be noted that, when the filter element 20 is normal and not blocked, the oil entering the filter body 10 will also generate pressure, and this pressure will cause the movable block 33 to move, thereby causing the display block 31 to move, and the marking point on the display block 31 may appear, which will make the driver mistakenly think that the filter element 20 is blocked and replace the filter element 20 with a new one, thereby causing unnecessary waste of materials. Therefore, when this pressure is generated, the spring will act on the movable block 33 to reset the movable block 33, avoiding the driver from mistakenly thinking that the filter element 20 is blocked.

[0045] Preferably, the filter body 10 includes a top cover 11 and a container 12, wherein the container 12 has an opening 1201, a plurality of inlets 1202, an outlet 1203 and a container cavity 1204, wherein the opening 1201 is connected to the container cavity 1204. Each of the inlets 1202 is connected to the container cavity 1204. The outlet 1203 is connected to the container cavity 1204. The detection channel 101 is connected to the container cavity 1204. The top cover 11 is detachably mounted on the opening 1201 of the container 12 to cover or open the opening 1201 connected to the container cavity 1204.

[0046] The filter element 20 is disposed in the container cavity 1204 , and the filter element 20 is installed on the inner wall forming the outlet 1203 .

[0047] Those skilled in the art can understand that, when the top cover 11 is installed on the container 12 , the engine oil enters the container cavity 1204 from each of the inlets 1202 , and after being filtered by the filter element 20 , the engine oil flows out from the container cavity 1204 to the outlet 1203 .

[0048] Preferably, the filter element 20 is implemented as a filter element.

[0049] Preferably, the top cover 11 is configured to be detachably mounted on the container 12 in a threaded connection with the container 12, so that the top cover 11 can be recycled and reused, thereby reducing waste of resources.

[0050] Further preferably, the filter body 10 further includes a mounting frame 13, the mounting frame 13 is arranged on the container cavity 1204 in a manner of being mounted on the inner wall forming the container cavity 1204, the mounting frame 13 has a channel 1301, the channel 1301 is connected to the container cavity 1204, and the channel 1301 is connected to the outlet 1203. As further preferably, the filter element 20 is mounted on the mounting frame 13 in a sleeve manner. Thus, the oil in the container cavity 1204 will enter the channel 1301 after the impurity filtering operation of the filter element 20, and then the oil will flow out from the outlet 1203 connected to the channel 1301.

[0051] In a preferred embodiment, the top cover 11 is further provided with a plurality of pressing blocks 111, each of which works in the container cavity 1204. It is understandable that when the top cover 11 is installed on the container 12, the pressing blocks 111 are pressed on the filter element 20, so that the filter element 20 can be stably installed on the mounting frame 13.

[0052] In another preferred embodiment, the detection channel 101 is disposed on the top cover 11, and the detection assembly 30 is disposed on the detection channel 101. In addition, since the detection assembly 30 has a high cost, when the top cover 11 is recycled, the detection assembly 30 is also recycled, and the recycled detection assembly 30 can be cleaned and reused.

[0053] In addition, the automobile oil filter further comprises a pressure relief member 40. In one embodiment, the mounting bracket 13 further comprises a mounting opening 1302, and the mounting opening 1302 is connected to the channel 1301. The pressure relief member 40 is mounted on the mounting opening 1302 of the mounting bracket 13.

[0054] It should be noted that when the filter 20 is completely blocked by impurities in the oil and cannot allow the oil to flow to the channel 1301, the oil pressure inside the container cavity 1204 will gradually increase until the pressure relief member 40 is pushed open, so that the oil in the container cavity 1204 will directly enter the channel 1301 from the installation port 1302 and then flow out from the outlet 1203. In this way, the engine can be lubricated by the oil.

[0055] It should be noted that, although the engine oil entering through the installation port 1302 has not been filtered by the filter element 20, the engine lubricated by the unfiltered engine oil will suffer less damage during operation than the engine that is not lubricated.

[0056] Preferably, the pressure relief member 40 is implemented to include a bypass valve.

[0057] It should be understood by those skilled in the art that the embodiments of the present invention described above and shown in the accompanying drawings are only examples and do not limit the present invention. The advantages of the present invention have been fully and effectively realized. The functions and structural principles of the present invention have been demonstrated and explained in the embodiments, and the embodiments of the present invention may be deformed or modified in any way without departing from the principles.
