Description

The present invention relates to a self-service oil changer, and more particularly to a self-service oil changer that can be operated by a user to change an oil product of a vehicle.

  According to statistics from the Taiwan Ministry of Transportation (equivalent to the Ministry of Land, Infrastructure, Transport and Tourism), the number of motorcycles in Taiwan has already reached 15 million in 2013, and the population of Taiwan is about 23 million. The density of motorcycles is several times higher than that of countries such as Singapore and Japan. Furthermore, the density of motorcycles is the highest in the world.

  In the repair and inspection of motorcycles, it is the most basic and common maintenance demand to change engine oil once every 1000 kilometers. At present, the vast majority of consumers take their motorcycles to a maintenance factory and entrust workers to change engine oil. The work steps are roughly as follows. (1) Loosen the engine oil drain plug to allow dirty engine oil to flow out of the engine. (2) When the amount of dirty engine oil flowing out decreases, the engine is left in the engine by tilting the vehicle body to the left. Drain the oil, (3) retighten the oil drain plug into the oil drain hole, (4) remove the plug of the oil hole using pliers, and insert a dedicated funnel into the oil hole, and (5) new engine oil (6) After injecting engine oil, remove the funnel and attach a stopper to the oiling hole to complete the engine oil replacement.

  However, as described above, there are many work steps necessary for exchanging the engine oil, and the time required for exchanging the engine oil is approximately 10 to 20 minutes. Since the skin of the hand is always in contact with engine oil, it tends to have a negative effect on health in the long run. In addition, consumers have to change oil during business hours of the maintenance factory, and therefore, it is extremely inconvenient because the timing of oil change is limited.

  In addition, every engine oil includes packaging materials such as engine oil bottles, opening seals and labels. In addition to the cost of the engine oil itself, the packaging material and the cost of manpower required for oil replacement are also included.

The cost is not a big burden for consumers, but the consumer is likely to forget the importance of vehicle maintenance, which is combined with the stress that the cost of consumable energy such as gasoline is constantly increasing. As a result, there is a problem that the engine is easily damaged over a long period of time and the service life is shortened by trying to suppress the average maintenance cost by running over hundreds of kilometers extra, rather than immediately changing the engine oil. It was.

  In addition, 15 million motorcycles in Taiwan use approximately 200 million engine oils every year, so the packaging materials such as engine oil bottles, opening seals, labels and cardboard boxes for packaging are enormous amounts of garbage. Therefore, it is a big problem in environmental conservation.

  On the other hand, in patents such as “Waste Oil Filtration Absorber” of the Republic of China Public Notice No. M417974 and “Reciprocating Oil Liquid Recovery Pump” of the Public Notice No. M426705, a device for sucking out all the oil liquid has been proposed.

The control unit 5 controls electric control members such as the touch panel 63, the dirty oil pump 41, the new oil pump 42, and the oil overflow pump 43 by stopping within the possible range and then paying the charge to the charge clearing machine 62. Control is performed so as to be in a standby state, and further control is performed so that the first valve 74 and the second valve 83 are closed.

  The user then selects the corresponding engine oil amount on the touch panel 63 according to the demand, transmits a control signal to the control unit 5, and then controls the control unit 5 to start the new oil pump 42 starting. Then, new engine oil is sucked into the new oil tank 2 and further passed through the third oil pipe 82 and injected into the liquid quantity cylinder 81 of the new oil temporary storage unit 8 to be temporarily stored. At this time, the user can see the new engine oil to be injected into the oil tank B through the viewing window 61. At this time, since the second valve 83 is kept closed, new engine oil is temporarily stored in the liquid quantity cylinder 81, and directly passes through the oil supply pipe 13 and is not injected into the oil tank B. Engine oil passing through the three oil pipes 82 can be measured by a flow meter 821. After the new engine oil injected into the liquid quantity cylinder 81 reaches a fixed amount, the control unit 5 can control the new oil pump 42 to stop operating.

  In addition, the user inserts the outer tube 11 into the oil tank B until the marker 111 of the outer tube 11 comes into contact with the inner peripheral wall of the oiling neck N.

It is located at the site of the lubrication neck N of tank B.

  Subsequently, the user presses the operation switch 141, and after the electrical signal is transmitted to the control unit 5, the control unit 5 performs control so that the dirty oil pump 41 starts to be operated, thereby attempting to replace the oil tank B. The old engine oil to be sucked is sucked through the oil suction pipe 12, further flows into the liquid quantity cylinder 71 through the first oil pipe 72 of the temporary dirty oil storage unit 7 and temporarily stored, and the user sees the sucked engine oil through the viewing window 61. Can do. At this time, since the first valve 74 is kept closed, the sucked-out engine oil is temporarily stored in the liquid quantity cylinder 71 and does not flow directly into the dirty oil tank 3.

  In addition, the control unit 5 can control the oil pump 41 to automatically stop after operating for a predetermined time. The above operating time is the time required to finish sucking out 95% or more of the engine oil in the oil tank B (generally about 20 seconds), but preferably 10 to 20 seconds are added. Set to In operation, if the oil pump 41 starts to suck air within a relatively short time, the pressure sensor 121 detects this and transmits an electrical signal to the control unit 5. The control unit 5 may control the alarm device 64 to issue a warning, thereby prompting the user to adjust the position of the outer tube 11 through display on the touch panel 63 or sound. In addition, since it is possible to ensure that the end of the oil absorption pipe 12 enters the bottom of the oil tank B with certainty, old engine oil can be continuously absorbed.

  It should be noted that if the oil changer for self-service of the present invention is provided with the temporary storage unit 7 for the dirty oil and the temporary storage unit 8 for the new oil, the first valve 74 and the second valve 83 stop the lubrication for a while. Therefore, the order of operation of the dirty oil pump 41 and the new oil pump 42 is not limited, and after one operation is completed, the next operation is activated again, or Even if one of them is activated with a delay, or activated at the same time, it does not affect the work result.

  Among them, if the oil pump 41 and the new oil pump 42 are activated at the same time, if the efficiency can be improved, it is preferably set to activate at the same time. On the other hand, if the temporary oil storage unit 7 and the new oil temporary storage unit 8 are not installed in the self-service oil changer, the oil pump B is activated so that the old engine in the oil tank B is activated. After the oil has been sucked up, new engine oil can be injected into the oil tank B by activating the new oil pump 42 to operate.
