Description

Technical Field

[0001] The present invention relates to the field of intelligent oil pumps, and more particularly to a portable pressure oil injection pump. Background Art

[0002] In modern industrial production, the lubrication operation of some mechanical equipment still relies on manual operation. For example, a portable oil can is used in conjunction with a funnel and a conduit to inject lubricating oil into a specified device. During the lubrication operation, two operators are often required to cooperate. One person is responsible for pouring the lubricating oil in the oil can, and the other person needs to hold the oil can and monitor the oil level gauge. Such an operation method is not only time-consuming but also has a relatively high labor intensity. Moreover, in the actual operation process, due to the limitation of the working space, it is difficult for the staff to maintain a comfortable posture during the refueling operation. During the process of adding a large amount of lubricating oil, it is easy to cause oil spillage due to posture deformation. Therefore, this operation method is difficult to ensure the accuracy of the dosage during the injection of lubricating oil.

[0003] At the same time, existing refueling equipment and oil pumping equipment are often separate. Before injecting lubricating oil, it is often necessary to clean the old lubricating oil. During this process, especially during the refueling operation of some heavy machinery, it is necessary to open the oil outlet at the bottom to drain the old oil. Many machines also need to be lifted, which is very time-consuming and laborious. Summary of the Invention

[0004] In order to overcome the above technical problems, the present invention provides a portable pressure oil injection pump, which can effectively be applicable to various workplaces for injecting lubricating oil, integrates the functions of oil pumping and oil injection, and uses a method of intelligent connection with a mobile phone, so that only one person can complete the refueling operation.

[0015] A further solution is that a flow direction adjusting pipe is slidably connected to the three-way joint. Two layers of adjusting grooves are provided on the flow direction adjusting pipe. One of the adjusting grooves, one layer of the adjusting grooves communicates with the lateral pipe connected to the external device and the lateral pipe connected to the inlet oil pump, and the other layer of the adjusting grooves communicates with the lateral pipe connected to the external device and the lateral pipe connected to the inlet oil pump.

[0016] A further solution is that two layers of oil extraction grooves are also provided on the flow direction adjusting pipe. One layer of oil extraction groove corresponds to the lateral pipe connected to the external device, and one layer of oil extraction groove corresponds to the inlet oil pump or the extraction oil pump. And a oil distribution groove is axially provided in the flow direction adjusting pipe. An oil distribution hole is provided on the housing.

[0019] A further solution is that a storage battery for the oil inlet pump, the oil extraction pump, and the control board to work is installed inside the housing.

[0020] A further solution is that a USB interface is installed on the housing. The USB interface can be connected to a power bank for the oil inlet pump, the oil extraction pump, and the control board to work.

[0021] Advantages of the present invention:

[0022] 1. In the present invention, the oil inlet pump sucks the oil liquid from the oil barrel through the external device connected to the oil barrel, and injects the oil liquid into the machine through the internal device connected to the machine that needs to be lubricated. When it is necessary to pump out the old lubricating oil in the machine, the circuit of the oil extraction pump is connected through the switch, and the oil liquid is pumped from the machine into the oil barrel. During this process, the external device can adapt to the actual site needs, and the pressure generated by the oil inlet pump and the oil extraction pump is used to realize the transfer of the oil liquid, avoiding the user from supporting the oil barrel by himself. The user only needs to observe the change of the oil liquid volume during this process, thereby improving the accuracy of refueling and oil extraction. During this process, the present invention adopts a double-pump body method, which avoids the mixing of new and old lubricating oils in the pump body, thereby affecting the quality of the oil products in the new lubricating oil.

[0023] 2. The present invention pre-imports the pump oil volumes of the inlet pump and the extraction pump per unit time under different temperatures and different oil products into the mobile application. By inputting the type of the oil product to be added and the volume of the oil product to be added, the application in the mobile phone can automatically calculate the working times of the inlet pump and the outlet pump, and transmit the above data to the control board through the Bluetooth relay. The control board will then control the working times of the inlet pump and the extraction pump. Through the above technical solution, more accurate lubricating oil filling can be achieved during the lubricating oil filling process, effectively preventing the oil from being over-added and spilled onto the bottom surface, thus avoiding the waste of lubricating oil and the pollution of the working environment.

[0024] 3. The present invention adjusts the adjustment grooves in the two flow direction adjustment pipes to the state where the inlet pump is connected to its corresponding external device. During the oil injection operation, the extraction pump and the oil circuit are completely closed. During the oil extraction operation, the adjustment grooves in the two flow direction adjustment pipes are adjusted to the state where the extraction pump is connected to its corresponding external device. In this way, during the oil extraction operation, the inlet pump and the connected oil circuit are completely closed. The advantage of this is that since the extraction pump mainly accumulates the used lubricating oil extracted from the machine, and the inlet pump mainly accumulates new lubricating oil, it avoids the mixing of the oil in the inlet pump and the oil in the extraction pump, resulting in the pollution of the new lubricating oil product.

[0025] 4. By means of an external pushing device, the position of the flow direction adjustment pipe is adjusted to correspond the component to be oil-extracted to its corresponding oil extraction groove, and at the same time, the oil circuits of other components are blocked through the flow direction adjustment pipe. In this way, the residual lubricating oil in the two external devices, the extraction pump and the inlet pump can be extracted respectively according to actual needs. During the extraction process, an external component such as a pump body is connected to the oil distribution hole, and the residual lubricating oil is extracted by using the oil distribution pipe to connect to the oil distribution groove.

[0038] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0039] To solve the technical problems proposed in the present invention;

[0040] As Figure 1 , Figure 3 , Figure 4 and Figure 5 shown, a portable pressure oil injection pump includes:

[0041] Housing 1, a handle is installed on the upper end surface of the housing 1, a power connection device 11 is installed on the housing 1, and a control board 2 is installed inside the housing 1;

[0042] Feed pump 3, the feed pump 3 is fixedly installed inside the housing 1, and a suction pump 4 is also fixedly installed inside the housing 1 corresponding to the feed pump 3;

[0043] External devices 5, there are two of the external devices 5, which respectively correspond to the inlet oil pump 3 and the extraction oil pump 4;

[0044] Three-way connectors 6, there are two of the three-way connectors 6, which are arranged between the inlet oil pump 3 and its corresponding external device 5 or between the extraction oil pump 4 and its corresponding oil pump. The three-way connector 6 includes three lateral pipes, and the three lateral pipes are respectively connected to the inlet oil pump 3, the extraction oil pump 4, and its corresponding external device 5 through internal connecting oil pipes 9.

[0045] A switch for controlling the operation of the inlet oil pump 3 or the extraction oil pump 4 is installed on the housing 1.

[0046] It should be noted that during the process of oil injection and oil extraction operations, one of the two external devices 5 needs to be connected to an oil barrel, and the other needs to be connected to the oil extraction or refueling equipment. When refueling, the power supply is connected through the power connection device 11, the circuit of the inlet oil pump 3 is connected through the switch. The inlet oil pump 3 sucks the oil from the oil barrel through the external device 5 connected to the oil barrel, and injects the oil into the machinery through the internal connection device connected to the machinery that needs to be lubricated. When the old lubricating oil in the machinery needs to be pumped out, the circuit of the extraction oil pump 4 is connected through the switch, and the oil is pumped from the machinery into the oil barrel. During this process, the external device 5 can be adapted to the actual site needs, and the transfer of the oil is realized through the pressure generated by the inlet oil pump 3 and the extraction oil pump 4, avoiding the need for the user to hold the oil barrel by themselves. The user only needs to observe the change of the oil volume during this process, thereby improving the accuracy of oil injection and oil extraction. During this process, the present invention adopts a double-pump body method, which avoids the mixing of new and old lubricating oils in the pump body, thereby affecting the quality of the oil products in the new lubricating oil.

[0047] As described above, a Bluetooth relay module is integrated on the control board 2, which can be connected to a mobile phone application through the Bluetooth protocol, and controls the operation of the inlet oil pump 3 or the extraction oil pump 4 through the oil injection and oil extraction options on the application.

[0048] In this way, during the work process, after completing the connection work of the external device 5 with the machinery and the oil barrel, the user can complete the oil injection work by relying on the mobile phone, avoiding the cumbersome operation of the user, and making the operation more in line with the requirements of intelligent and user-friendly control.

[0049] The fuel injection volume and the fuel output volume can be set through a mobile application. A temperature control module is integrated on the Bluetooth relay module. At the same time, the changes in the oil flow rate of the inlet oil pump 3 and the extraction oil pump 4 when working with different oils and at different temperatures are imported into the mobile application. Before using the oil pump, the type of oil to be added can be selected on the application, and the working time of the oil pump can be controlled according to the data of the oil flow rate.

[0050] It should be noted that the reasonable fuel injection volume and fuel output volume are set according to the volume of the equipment to be filled. The advantage of this is that it can effectively prevent the overfilling of the oil fluid, resulting in the spilling of the oil fluid on the ground, thus causing waste of the lubricating oil fluid and pollution of the working environment. At the same time, the viscosities of different oils are different, and the viscosity of the same oil is also different at different temperatures. However, the power of the inlet oil pump 3 and the outlet oil pump remains unchanged. Under the above variable conditions, the volume of oil that the inlet oil pump 3 and the outlet oil pump can transport per unit time is also different. Therefore, by importing the above data into the mobile application in advance, and inputting the type of oil to be added and the volume of the oil to be added, the mobile application can automatically calculate the working time of the inlet oil pump 3 and the outlet oil pump, and transmit the above data to the control board 2 through the Bluetooth relay. The control board 2 will then control the working time of the inlet oil pump 3 and the extraction oil pump 4. Through the above technical solution, more accurate filling can be achieved during the lubricating oil filling process.

[0051] As Figure 3 and Figure 10 shown, the external device 5 includes an oil inlet ring 51, a turntable 52 and a tightening spring 53. The oil inlet ring 51 is fixedly installed on the housing 1. The oil inlet ring 51 is connected to the lateral pipe of the corresponding three-way joint 6 through an internal connecting pipe 9. The turntable 52 is rotatably connected to the oil inlet ring 51. A tightening spring 53 is provided at the other end of the turntable 52 relative to the position of the oil inlet ring 51. The innermost end of the tightening spring 53 is fixedly connected to the turntable 52, and the outermost end is fixedly connected to the housing 1. An external connecting pipe 54 is wound on the turntable 52. The innermost side of the external connecting pipe 54 is communicated with the inside of the turntable 52. A chamber is provided in the turntable 52 that is communicated with the inside of the oil inlet ring 51. The external connecting pipe 54 passes through the housing 1.

[0052] It should be noted that when connecting the oil barrel and the machine through the external device 5, the external oil pipe 54 can be directly pulled out from the housing 1. When the required length is reached, the external oil pipe 54 is placed into the machine or the oil barrel. In this way, during the process of the user using the oil inlet pump 3 to fill or extract lubricating oil, the working site is not restricted, and the oil barrel can also be placed at a convenient working location. During this process, the tightening spring 53 is always in a taut state. After completing the work of filling or extracting lubricating oil, when the external oil pipe 54 is retracted, the tightening spring 53 can drive the turntable 52 to retract the external oil pipe 54. When the lubricating oil flows in the external device 5, the lubricating oil can pass through the cavity in the oil inlet ring 51 and the turntable 52 to achieve the connection between the external oil pipe 54 and the internal oil pipe 9, thereby completing the transfer of the lubricating oil.

[0053] As Figure 3 , Figure 9 and Figure 10 shown, a flow direction adjusting pipe 7 is slidably connected to the three-way joint 6. Two layers of adjusting grooves 71 are formed on the flow direction adjusting pipe 7. One of the adjusting grooves 71, one layer of the adjusting grooves 71 connects the lateral pipe connected to the external device 5 and the lateral pipe connected to the oil inlet pump 3, and the other layer of the adjusting grooves 71 connects the lateral pipe connected to the external device 5 and the lateral pipe connected to the oil inlet pump 3.

[0054] It should be noted that during the process of refueling, the adjusting grooves 71 in the two flow direction adjusting pipes 7 are adjusted to the state where the oil inlet pump 3 is connected to its corresponding external device 5. During the oil injection operation, the oil extraction pump 4 and the oil circuit are completely closed. During the process of oil extraction operation, the adjusting grooves 71 in the two flow direction adjusting pipes 7 are adjusted to the state where the oil extraction pump 4 is connected to its corresponding external device 5. In this way, during the process of oil extraction operation, the oil inlet pump 3 and the connected oil circuit are completely closed. The advantage of this is that since the oil accumulated in the oil extraction pump 4 is mainly the used lubricating oil extracted from the machine, and the oil accumulated in the oil inlet pump 3 is mainly new lubricating oil, it avoids the mixing of the oil in the oil inlet pump 3 and the oil in the oil extraction pump 4, resulting in the contamination of the quality of the new lubricating oil.

[0055] As Figure 3 , Figure 5 and Figure 9 shown, two layers of oil extraction grooves 72 are also formed on the flow direction adjusting pipe 7. One layer of the oil extraction grooves 72 corresponds to the lateral pipe connected to the external device 5, and one layer of the oil extraction grooves 72 corresponds to the oil inlet pump 3 or the oil extraction pump 4. And a oil distribution groove 73 is axially formed in the flow direction adjusting pipe 7. A oil distribution hole 12 is provided on the housing 1, and the oil distribution hole 12 and the oil distribution groove 73 are connected by an oil distribution pipe 74.

[0056] It should be noted that during the operation of the oil extraction pump 4, when the oil in the machine is pumped out and the external oil pipe 54 and the internal oil pipe 9 connected to the machine are also pumped dry, the oil extraction pump 4 can no longer pump oil but sucks air. At this time, the oil extraction pump 4 cannot obtain enough thrust to push the lubricating oil accumulated in itself and the external oil pipe 54 and the internal oil pipe 9 connected to the fuel tank into the fuel tank. In this way, if the oil extraction pump 4 is not used for a long time, the lubricating oil may emulsify, resulting in the inability of the oil extraction pump 4 to continue working. Similarly, the oil inlet pump 3 also has the phenomenon of oil accumulation. At this time, by adjusting the position of the flow direction regulating pipe 7 through an external pushing device, the components that need to be pumped are corresponding to their corresponding pumping grooves 72, and at the same time, the oil circuits of other components are blocked through the flow direction regulating pipe 7, so that the residual lubricating oil in the two external devices 5, the oil extraction pump 4 and the oil inlet pump 3 can be extracted separately according to actual needs. During the extraction process, the external components such as the pump body are connected to the oil distribution hole 12, and the residual lubricating oil is extracted by using the oil distribution pipe 34 to communicate with the oil distribution groove 73. At the same time, threaded holes are provided on the oil extraction pump 4 and the oil inlet pump 3 corresponding to the oil pumping positions inside them for extracting the lubricating oil inside. When the oil extraction pump 4 and the oil inlet pump 3 are working, bolts are used to block them.

[0057] As Figure 1 、 Figure 2 、 Figures 5 to 8 shown, a oil distribution mechanism 8 is provided on the housing 1 corresponding to the oil distribution hole 12. The turntable 52 in the external device 5 corresponding to the oil extraction pump 4 passes through the housing 1, and the end passing through the housing 1 is in a spline shape. The oil distribution mechanism 8 includes an oil distribution housing 81, a first oil distribution gear 82 and a second oil distribution gear 83. The first oil distribution gear 82 and the second oil distribution gear 83 are rotatably connected to the oil distribution housing 81. The first oil distribution gear 82 and the second oil distribution gear 83 are meshed with each other. The first oil distribution gear 82 is key-connected to the turntable 52. An oil distribution pump 85 is fixedly installed on the oil distribution housing 81. The oil distribution pump 85 is a piston pump. One end of the second oil distribution gear 83 is hinged with an oil distribution connecting rod 84, and the other end of the oil distribution connecting rod 84 is connected to the piston of the oil distribution pump 85. One end of the oil distribution pump 85 corresponds to the oil distribution hole 12 and is inserted into the oil distribution hole 12. The oil distribution housing 81 can be fixedly installed on the housing 1 through bolts.

[0058] During the process of winding and unwinding the external oil pipe 54 in the external device 5 corresponding to the oil extraction pump 4, the turntable 52 drives the rotation of the first oil distribution gear 82 during rotation. The first oil distribution gear 82 drives the rotation of the second oil distribution gear 83 and the oil distribution disc. During the rotation of the oil distribution disc, the oil distribution pump 85 is driven through the oil distribution connecting rod 84. The oil distribution pump 85 pumps out the residual lubricating oil through the oil distribution hole 12. At the same time, the above device is convenient for disassembly and cleaning.

[0059] As shown Figure 1 in the figure, a damping cylinder 13 sleeving an external oil pipe 54 is fixedly installed on the housing 1. The damping cylinder 13 is made of rubber material and clamps the external oil pipe 54.

[0060] The advantage of this is that it will have a restraining effect on the external oil pipe 54 during the process of pulling out the external oil pipe 54, preventing it from sliding easily.

[0061] A storage battery for the oil inlet pump 3, the oil extraction pump 4 and the control board 2 to work is installed inside the housing 1.

[0062] Because not all places are convenient to connect to the power supply during the working process, the above device can rely on the storage battery to provide power, thereby increasing the working environment it can adapt to.

[0063] A USB interface is installed on the housing 1. The USB interface can be connected to a power bank for the oil inlet pump 3, the oil extraction pump 4 and the control board 2 to work.

[0064] In this way, even when the storage battery is out of power, emergency power supply can be provided through the power bank, because the power bank has a wide range of uses and is easily available with the popularization of shared power banks.

[0065] In the description of the present invention, it should be understood that the terms "upper", "lower", "left", "right", etc. indicating the orientation or position relationship are based on the orientation or position relationship shown in the drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation and specific orientation structure and operation. Therefore, it should not be construed as a limitation to the present invention. In addition, "first" and "second" are only for the purpose of description, and cannot be understood as indicating or implying relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of the present invention, unless otherwise specified, the meaning of "plurality" is two or more.

[0066] In the description of the present invention, it should be noted that unless otherwise clearly defined and limited, the terms "installed", "connected", "connected" and the like should be understood in a broad sense. For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be directly connected, or indirectly connected through an intermediate medium, and it can be the communication inside two elements. For those of ordinary skill in the art, the specific meanings of the above terms in the present invention can be understood according to specific situations.

[0067] The above has described in detail an embodiment of the present invention, but the above content is only a preferred embodiment of the present invention and cannot be considered as defining the scope of implementation of the present invention. All equivalent changes and improvements made in accordance with the scope of the application of the present invention shall still fall within the scope covered by the patent of the present invention.
