Description

{Self-Help Oil Changing Apparatus}

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a magnetic force type oil changing apparatus, and more particularly, to a magnetic force type oil changing apparatus that can be operated by a user to replace a vehicle oil.

Replacing engine oil every 1000 km is the basic and most common way to maintain a motorcycle. Most consumers send their motorcycles to the garage and ask the mechanic to replace the engine oil. The engine oil replacement process generally involves (1) removing the bolts from the oil drain holes to drain the dirty engine oil, and (2) leaning the motorcycle to the left as the dirty engine oil flow becomes smaller to drain the remaining dirty engine oil (4) using a plier to remove the plug from the oil fill port, inserting a funnel into the oil fill port, (5) dislodging the clean engine oil from the funnel, And (6) after completing the charging of clean engine oil, removing the funnel and reattaching the plug to the oil fill port to achieve engine oil replacement.

However, the cumbersome engine oil replacement process takes 10 to 20 minutes, which is inefficient. Also, it is common for engine oil to get on the skin of a mechanic's hand, which is harmful to health after years of work. In addition, the engine oil replacement process is generally done within the working hours of the workshop, and is therefore limited by this working time, which is not always convenient for the consumer. Further, each engine oil bottle includes a bottle body, a sealing film, and at least one label. These packaging materials, in addition to the labor costs of the mechanic and the engine oil, result in cost to the consumer. The total cost per engine oil change is about 150 to 250 NT $ in Taiwan. Although the cost may not be a burden on the consumer, consumers often overlook the importance of regular maintenance of the vehicle and are reluctant to regularly replace the engine oil due to the increased cost of consumable energy, including gasoline. In other words, consumers would rather drive hundreds of kilometers to reduce average maintenance costs. As a result, the vehicle engine is susceptible to damage, thereby reducing the life span. In addition, 15 million motorcycles consume about 200 million engine oil bottles. Due to the packing materials of such engine oil bottles, a large amount of waste is generated and causes a great problem in environmental protection.

Referring to FIGS. 1 and 2, a magnetic type oil replacement apparatus according to the present invention includes a nozzle 1, a clean oil tank 2, a dirty oil tank 3, an oil pressure control module 4, Unit 5 as shown in Fig. The nozzle (1) receives tubes which communicate with the clean oil tank (2) and the dirty oil tank (3), respectively. The control unit 5 controls the oil pressure control module 4 to cause the nozzle 1 to draw the dirty oil from the vehicle and then to charge the vehicle with the clean oil so that the user can perform the oil change of the vehicle himself Support. Preferably, the magnetic type oil replacing apparatus further includes a housing 6 for accommodating the clean oil tank 2, the dirty oil tank 3, the oil pressure control module 4, and the control unit 5. Thus, the housing 6 can protect such parts from damage and breakage. The oil to be replaced by the magnetic type oil changing apparatus according to the present invention may be engine oil, gear oil, or other oil. The structural arrangement of the magnetic oil change apparatus according to the present invention may vary depending on the type of vehicle such as a motorcycle, an automobile, or a truck. An embodiment of the magnetic force type oil replacement apparatus according to the present invention is described as an example in which engine oil of a motorcycle is replaced without any limitation.

Referring to FIG. 3, the nozzle 1 includes an outer tube 11, an oil suction tube 12, and an oil filling tube 13. The outer tube (11) is exposed to the outside of the housing (6). Each of the oil suction tube 12 and the oil filling tube 13 has an exposed portion exposed to the outside of the housing 6. The outer tube 11 is a rigid tube having a predetermined shape. The outer tube 11 has an insertion end 11a to be inserted into the engine oil tank B.

The outer tube 11 may further include a label portion 111 for supporting the user to insert the outer tube 11 in a fixed depth in the engine oil tank B. In one example, the label portion 111 may be a mark engraved or bonded to the outer edge of the outer tube 11, or it may be a protrusion formed on the outer edge of the outer tube 11, May be a bend of the tube (11). When the user inserts the outer tube 11 to a predetermined depth in the oil filled neck N of the engine oil tank B, the label portion 111 is inserted into the engine oil tank B of the outer tube 11 And contacts the inner edge of the oil filled neck (N) to prevent insertion movement.

Preferably, the oil extraction tube 12 and the oil fill tube 13 are flexible hoses and are housed in an outer tube 11 that provides protection. When the outer tube 11 is inserted into the engine oil tank B, one end of each of the oil suction tube 12 and the oil filling tube 13 is also disposed in the engine oil tank B. Specifically, one end of each of the oil suction tube 12 and the oil filling tube 13 to be disposed in the engine oil tank B extends outward from the insertion end 11a of the outer tube 11. The length of the oil suction tube 12 extending outward from the insertion end 11a of the outer tube 11 is equal to the length of the oil filling tube 13 extending outwardly from the insertion end 11a of the outer tube 11 May or may not be the same. The length of the oil suction tube 12 extending outwardly from the insertion end 11a of the outer tube 11 is preferably the length of the oil filling tube 13 extending outwardly from the insertion end 11a of the outer tube 11, . Therefore, when the oil suction tube 12 and the oil filling tube 13 are inserted into the engine oil tank B together with the outer tube 11, the oil suction tube 12 is formed in the lower part of the engine oil tank B And the oil filling tube 13 is located at the oil filling neck N. This prevents the oil filling tube 13 from being locked to viscous dirty oil having a large amount of impurities. The oil suction tube 12 and the other ends of the oil filling tube 13 draw the oil to be replaced through the oil suction tube 12 into the dirty oil tank 3 and through the oil filling tube 13, And communicates with the dirty oil tank 3 and the clean oil tank 2 so as to fill the clean oil from the engine 2 to the engine oil tank B, as will be described in detail later. The oil suction tube 12 further includes a pressure sensor 121 electrically connected to the control unit 5 to detect whether the fluid flowing in the oil suction tube 12 is liquid or gas.

The grip 14 includes a start switch 141 electrically connected to the control unit 5. After the outer tube 11 is inserted into the engine oil tank B, the user can operate the start switch 141 to advance the engine oil replacement operation. Preferably, the receiving tube 15 is also a flexible hose. One end of the receiving tube 15 is connected to the grip 14. Each exposed portion of the oil suction tube 12 and the oil filled tube 13 is surrounded by the receiving tube 15 for protection.

3, the nozzle 1 preferably further includes an overflow tube 16 extending through the outer tube 11, the grip 14, and the receiving tube 15. One end of the overflow tube (16) communicates with the dirty oil tank (3). The other end of the overflow tube 16 extends outward from the insertion end 11a of the outer tube 11. [ The length of the overflow tube 16 extending outward from the insertion end 11a of the outer tube 11 is equal to the length of the oil filling tube 13 extending outward from the insertion end 11a of the outer tube 11 Shorter. Thus, excessive engine oil can be removed immediately, and engine oil overflow can be avoided.

Referring to FIGS. 1 and 2, the clean oil tank 2 receives clean engine oil, and the dirty oil tank 3 receives the replaced dirty engine oil. The clean oil tank 2 and the dirty oil tank 3 are open tanks so that the pressure of these tanks is not significantly changed due to an increase or decrease in the amount of oil stored in these tanks, It is possible to maintain a smooth operation of drawing the oil or filling the oil in the tanks. The clean oil tank 2 and the dirty oil tank 3 may be mounted at predetermined positions of the housing 6 and arranged to align with each other in the vertical direction or the horizontal direction.

The dirty oil pump 41 is connected to the oil suction tube 12 and communicates with the dirty oil tank 3. When the dirty oil pump 41 is operated, a negative pressure is generated with respect to the oil suction tube 12 to draw the dirty engine oil to be replaced into the dirty oil tank 3 through the oil suction tube 12. The clean oil pump 42 communicates with the oil filling tube 13 and the clean oil tank 2. When the clean oil pump 42 is operated, a negative pressure is generated with respect to the clean oil tank 2 to charge the clean engine oil into the oil filling tube 13. The overflow pump 43 is connected to the overflow tube 16 and communicates with the dirty oil tank 3 to continuously draw air or draw excess engine oil and excess engine oil is supplied to the oil fill tube 13 To form a negative pressure on the overflow tube 16 so as to lead the excessive engine oil into the dirty oil tank 3. [

In addition, the magnetic type oil change apparatus according to the present invention includes a dirty oil temporary storage assembly 7 and a clean oil temporary storage assembly 8. [ Each of the dirty oil temporary storage assembly 7 and the clean oil temporary storage assembly 8 has provisional storage tanks 71 and 81 at predetermined positions in the housing 6. The housing 6 may include a window 61 aligned with the temporary storage tanks 71, 81 so that the user can see the temporary storage tanks 71, 81. Temporary storage tanks 71 and 81 provide provisional storage spaces for dirty engine oil and clean engine oil, respectively. The user can see how much dirty engine oil is drawn from the engine oil tank B of his / her vehicle and know the amount of clean engine oil to be charged.

In this embodiment, the dirty oil temporary storage assembly 7 further comprises a first oil tube 72, a second oil tube 73, and a first valve 74. The first oil tube 72 has two ends connected to one end of the dirty oil pump 41 and the temporary storage tank 71, respectively. The second oil tube 73 has two ends connected to the temporary storage tank 71 and the dirty oil tank 3, respectively. Preferably, the second oil tube 73 is connected to the temporary storage tank 71 at a position adjacent to the lower portion of the temporary storage tank 71. The first valve (74) is mounted to the second oil tube (73) and electrically connected to the control unit (5).

The clean oil temporary storage assembly 8 further includes a third oil tube 82 and a second valve 83. The third oil tube 82 has two ends connected to one end of the clean oil pump 42 and the temporary storage tank 81, respectively. The third oil tube 82 preferably includes a flow meter 821 electrically connected to the control unit 5 to measure the amount of clean engine oil charged in the temporary storage tank 81. The other end of the oil filling tube 13 communicates with the temporary storage tank 81, and is preferably located adjacent to the lower portion of the temporary storage tank 81. The second valve 83 is mounted to the oil filling tube 13 and is electrically connected to the control unit 5. The first and second valves 74, 83 may be electromagnetic valves, but are not limited to this example.

In addition to the above construction, the magnetic oil replacer according to the present invention may include other components to provide additional functionality.

In this embodiment, the housing 6 further includes a payment device 62, a touch control screen 63, and an alarm device 64, both of which are electrically connected to the control unit 5. The payment device 62 may include at least one slot for receiving coins and / or banknotes. After confirming payment, the engine oil replacement process can be carried out. The touch control screen 63 is configured to be operated by a user to control the amount of clean oil to be replaced, display an operating state, or display an operation command. The alarm device 64 can inform the user of the situation or provide a solution to the problem to the user. In one example, the alarm device 64 is a flashing alarm light when a problem occurs, and the touch control screen 63 may display a command for solving the problem. In another example, the alarm device 64 is a microcomputer having a loudspeaker. The loudspeaker produces a sound when a problem occurs. Loudspeakers can output audio commands that help users solve problems. The housing 6 may also preferably include an invoice machine 65 electrically connected to the control unit 5 and a display 66 electrically connected to the control unit 5. [ The display 66 may broadcast outdoor advertisements, instant news, or live sports so that the user does not feel bored in the atmosphere. In addition, the housing 6 may receive an air compressor (not shown) so that the user can inject air into the wheels of the vehicle.

3 and 4, when the user intends to replace the engine oil of his / her vehicle using the magnetic type oil replacement apparatus according to the present invention, the vehicle is parked in an area reachable to the nozzle 1 have. The user pays through the payment device 62 and the touch control screen 63, the dirty oil pump 41, the clean oil pump 42 and the overflow pump 43 are connected to the control unit 5 And is in a standby state. The first and second valves 74 and 83 are in a closed state.

Next, the user selects the amount of engine oil through the touch control screen 63 and a control signal is transmitted to the control unit 5 which controls the clean oil pump 42 to operate. The clean engine oil is drawn from the clean oil tank 2 and is directed through the third oil tube 82 into the temporary storage tank 81 of the clean oil temporary storage assembly 8, Clean engine oil filled in tank B can be seen. It is noted that the second valve 83 can be temporarily stored in the temporary storage tank 81 without the clean engine oil flowing directly into the engine oil tank B through the oil filling tube 13 in the closed state . The amount of engine oil flowing through the third tube 82 can be measured by the flow meter 821. After charging the selected amount of clean engine oil into the temporary storage tank 81, the clean oil pump 42 starts to operate under the control of the control unit 5. [

On the other hand, the user inserts the outer tube 11 into the engine oil tank B until the label portion 111 comes into contact with the inner edge of the oil filled neck N. [ In this case, one ends of the oil suction tube 12 and the oil filling tube 13 are also in the engine oil tank B. The oil suction tube 12 can reach the lower portion of the engine oil tank B substantially while the oil fill tube 13 is located in the oil filled neck N. [

The control unit then activates the dirty oil pump 41 to control the dirty oil in the engine oil tank B to start the dirty oil pump 41. [ So that the engine oil is sucked out through the oil suction tube 12. The dirty engine oil flows into the temporary storage tank 71 of the dirty oil temporary storage assembly 7 and is temporarily stored in this temporary storage tank so that the dirty engine oil is discharged from the engine oil tank B through the window 61, Oil can be seen. The dirty engine oil can be temporarily stored in the temporary storage tank 71 without flowing directly into the dirty oil tank 3 since the first valve 74 is in the closed state.

The dirty oil pump 41 stops operation after a predetermined operation time under the control of the control unit 5. [ The operating time is preferably the time (about 20 seconds) required to draw in an amount exceeding 95% of the dirty engine oil from the engine oil tank B, preferably 10 to 20 seconds, which is the buffering time . In operation, when the dirty oil pump 41 sucks air after a predetermined time, the pressure sensor 121 starts and transmits an electrical signal to the control unit 5, To transmit an alarm message displayed on the audio alert or touch control screen 63 to inform the user that the position of the outer tube 11 should be controlled by controlling the position of the outer tube 11, (12) reaches the lower portion of the engine oil tank (B).

The first and second valves 74 and 83 may provide a pause effect during the oil fill operation if the magnetic type oil change apparatus according to the present invention includes the dirty oil temporary storage assembly 7 and the clean oil temporary storage assembly 8. [ Can be provided. Therefore, the order of operation of the dirty oil pump 41 and the clean oil pump 42 is not limited, that is, it is possible to start the other one after starting one, or to delay the start of one of them , Or both of them simultaneously. The result of the operation is not affected. It is preferable to set the simultaneous start-up if the simultaneous start-up of the dirty oil pump 41 and the clean oil pump 42 increases the efficiency. On the other hand, if the magnetic type oil replacement apparatus according to the present invention does not include the dirty oil temporary storage assembly 7 and the clean oil temporary storage assembly 8, the dirty oil pump 41 The clean oil pump 42 can be started to charge the clean engine oil into the engine oil tank B only after the dirty engine oil is sucked.

5 and 6, while the clean engine oil and the dirty engine oil are respectively charged into the temporary storage tanks 71 and 81, the gas in the temporary storage tanks 71 and 81 is gradually compressed, The control unit 5 switches the first and second valves 74 and 83 to the open state after the dirty oil pump 41 is shut down after the operation for the predetermined time and the temporary storage tanks 71 and 81, The dirty engine oil in the temporary storage tank 71 flows into the dirty oil tank 3 through the first valve 74 and the second oil tube 73 by the potential and the gas pressure in the temporary storage tank 71. [ The clean engine oil in the temporary storage tank 81 flows into the engine oil tank B through the second valve 83 and the oil filling tube 13 to achieve the magnetic type oil replacement process.

Referring to FIGS. 7 and 8, during normal operation, the oil filling tube 13 charges a predetermined amount of clean engine oil into the engine oil tank B. However, in case of improper operation or failure by the user, the oil filling tube 13 can charge the excessive clean engine oil into the engine oil tank B. In this case, the overflow pump 43 can be continuously operated to draw excess engine oil through the overflow tube 16, and excess engine oil can be introduced into the dirty oil tank 3, B of the engine oil can be avoided and an appropriate operating environment can be maintained.

In view of the foregoing, the operating steps of the magnetic type oil change apparatus according to the present invention are easy. The inflow of the dirty engine oil and the filling of the clean engine oil can be performed simultaneously after the insertion end 11a of the nozzle 1 is inserted into the engine oil tank B at a cost. The engine oil replacement process can be accomplished in 3 to 5 minutes, which can increase the oil replacement efficiency.

In operation of the self-powered oil change device according to the present invention, the user can simply remove the cap of the engine oil tank B before the oil change process and place the cap in place after the oil change process, The risk of exposure can be reduced and thus the adverse effects on health can be avoided.

The user can operate the magnetic type oil change apparatus according to the present invention at any time without being restricted by the working hours of the workshop, thereby increasing the user's convenience.

Since a large amount of clean engine oil in the clean oil tank 2 is directly stored in the magnetic type oil replacement apparatus according to the present invention, there is no need to package a small amount of engine oil per bottle so that the cost for packaging the materials is largely saved And the material cost can be reduced. In addition, the user can operate a self-lubricating oil replacement device to save labor costs, thereby greatly reducing the cost of oil replacement. Taking the engine oil change as an example, the cost is about NT $ 100 in Taiwan by using the magnetic oil change apparatus according to the present invention, which is much lower than the 150 to 250 NT $ required in the conventional engine oil change. The consumer can see a cost saving effect and is therefore encouraged to regularly replace the engine oil. Therefore, the life span of the engine can be extended through regular maintenance of the vehicle.

Further, the magnetic type oil replacement apparatus according to the present invention can effectively reduce waste and protect environment by largely saving packaging materials.

Accordingly, the invention disclosed herein may be embodied in other specific forms without departing from the spirit or essential characteristics thereof, and the embodiments described herein are to be considered in all respects only as illustrative and not restrictive Should be considered. The scope of the invention is indicated by the appended claims rather than the foregoing description, and all changes which come within the meaning and range of the claims are intended to be embraced therein.
