Abstract

An oil quality examiner has a detection module (15) in a shell (11) and a display unit (16) on the shell (11). The display unit (16) and the detection module (15) are connected for displaying detected results. The detection module (15) has a first detection electrode (31) and a second detection electrode (41). The first detection electrode (31) obtains an oil quality standard value (for example from a new or unused oil sample) and temporarily stores it in a storage area. The second detection electrode is used to obtain a target value (i.e. from the oil to be tested). The detection module (15) compares the target value and the oil quality standard value to determine the oil quality of the target value. The oil quality examiner is used to detect the quality of brake oil (i.e. brake fluid). The first and second detection electrodes may be pivotally connected to the shell.

Description

OIL QUALITY EXAMINER

Field of Invention

The invention relates to a detection device and, in particular, to an oil quality examiner that compares sample oil with a pre-stored oil quality standard value.

Related Art During its use, brake oil may generate water as its temperature rises.

Therefore, its water content gradually increases. Once the water content reaches a specific ratio, the brake oil starts to deteriorate. The oil's efficiency of transferring pressure to the brake pump also becomes worse. In that case, one has to replace the brake oil.

Currently, the device for examining brake oil mainly puts a detection electrode set into a main brake pump to detect the water content therein, thereby determining whether the brake oil has deteriorated. The conventional examining device is built in with the brake oil standard values for specific brands. Therefore, it can only be used to detect specific brake oil. However, there are many different brands of brake oil on the market, and different vehicles use different types of brake oil.

Consequently, the conventional examining device cannot be used to test all kinds of oil. That is, one has to purchase more than one oil quality examiner for that.

SUMMARY OF THE INVENTION

An objective of the invention is to provide an oil quality examiner suitable for test the quality of all kinds of oil.

Another objective of the invention is to provide an oil quality examiner that can quickly determine oil quality.

To achieve the above-mentioned objectives, the disclosed oil quality examiner has a detection module inside a shell. The shell has a display unit connected with the detection module for displaying a detected result. The invention is featured in that the detection module has a first detection electrode and a second detection electrode.

The first detection electrode obtains an oil quality standard value and temporarily stores it in a storage area. The second detection electrode obtains a target value and compares the target value with the oil quality standard value, thereby determining the oil quality of the target value.

The invention will become more fully understood from the detailed description given herein below illustration only, and thus is not limitative of the present invention, and wherein: FIG. 1 is a three-dimensional exploded view of the invention; FIG. 2 is a three-dimensional view of the invention; FIG. 3 is a three-dimensional view of the invention from another perspective; FIG. 4 is a locally exploded view of the invention; and FIG. 5 is a schematic view showing the invention in use.

DETAILED DESCRIPTION OF TIlE INVENTiON

The present invention will be apparent from the following detailed description, which proceeds with reference to the accompanying drawings, wherein the same references relate to the same elements.

Please refer to FIGS. 1, 2, and 3. The disclosed oil quality examiner has a shell II, consisting of an upper cover 12 and a lower cover 13. The shell 11 is formed with an accommodating space 14 for accommodating a detection module 15.

The detection module 15 has a storage area (not shown). The upper cover 12 of the shell 11 is provided with a display unit 16 connected with the detection module 15 for displaying a detected result. The upper cover 12 is provided with a memory switch 17, a detection switch 18, and a power switch 19, all of which are electrically connected with the detection module 15 for controlling the on and off of the detection module 15. The lower cover 13 of the shell 11 is formed with a groove 21 and an accommodating part 22 for accommodating batteries (not shown). A notch 23 is formed by the groove 21 and connected with the groove 21.

The detection module 15 has a first detection electrode 31 and a second detection electrode 41. The first detection electrode 31 has a connection end 32 and a first sensing end 33. The first detection electrode 31 is electrically connected with the detection module 15. The first detection electrode 31 is further pivotally connected to one end of the groove 21 of the lower cover 13 by its connection end 32.

The first sensing end 33 is used to detect a new oil sample, obtaining an oil quality standard value, sending it back to the detection module 15 and storing it in the storage area. A cylinder element 34 whose inner diameter is equal to the outer diameter of the first sensing end 33 is mounted on the first sensing end 33.

The second detection electrode 41 has a pivotal end 42 and a second sensing end 43. The second detection electrode 41 is also electrically connected with the detection module 15. The second detection electrode 41 is connected to one side in the lower cover 13 of the shell 11 using its pivotal end 42. The second sensing end 43 examines an oil sample and obtains a target value. The target value is returned to the detection module 15 for a comparison.

The first detection electrode 31 and the second detection electrode 41 are pivotally disposed in the groove 21 and its side on the lower cover 13 of the shell, respectively. Therefore, both the first detection electrode 31 and the second detection electrode 41 can perform a swing action. When the invention is not in use, as shown in FIG. 3, one can fold the first detection electrode 31 into the groove 21 in the lower cover 13 of the shell 11. The second detection electrode 41 is folded to the side of the shell 11.

When the invention is in use, as shown in FIG. 4, the user starts it power via the power switch 19. Afterwards, the operator flips the first detection electrode 31 via the notch 23 of the shell 11, so that the first sensing end 33 leaves the groove 21 of the lower cover 13. Then the first sensing end 33 is immersed in a new oil sample.

The first sensing end 33 starts to analyze the new oil sample and obtains a oil quality standard value. Once the operator presses down the memory switch 17, the oil quality standard value is temporarily stored in the storage area of the detection module 15. Afterwards, the operator flips the second detection electrode 41 and immerses it in an oil sample to be examined. hi this case, the second sensing end 43 analyzes the oil sample and obtains a target value. When the operator presses down the detection switch 18, the detection module 15 performs a comparison procedure for the target value obtained by the second sensing end 43 and the oil quality standard value stored in the storage area. The detection module 15 then transmits the compared result to the display unit 16 and displays it thereon.

Using the invention to examine different oil samples, one only needs to use the first detection electrode 31 to extract the oil quality standard values of them.

Therefore, the invention can be used to examine all oil samples. The detection module 15 compares the target value and the standard value. The difference is shown on the display unit 16. Therefore, the operator can quickly determine the quality of the oil sample.

It should be emphasized that, as shown in FIG. 2, the display unit 16 is divided into a pass region 161, a warning region 162, and a fail region 163. The detection module 15 can be further electrically connected with a warning unit (not shown).

When the detected result of the detection module 15 does not pass, the detection module 15 drives the warning unit to set off an alanii sound notif'ing the operator.

Although the invention has been described with reference to specific embodiments, this description is not meant to be construed in a limiting sense.

Various modifications of the disclosed embodiments, as well as alternative embodiments, will be apparent to persons skilled in the art. It is, therefore, contemplated that the appended claims will cover all modifications that fall within the true scope of the invention.
