Description

Technical Field

[0001] This utility model relates to the technical field of oil pumps, and in particular to a portable oil pump. Background Technology

[0002] As is well known, a portable oil pump is an electronic product that is easy for users to carry and use to transfer oil, such as gasoline and diesel, from one container to another. A portable oil pump generally includes a main unit, a suction pipe, and a discharge pipe. The main unit contains a circuit board, and the pump body, electrically connected to the circuit board, is located inside the suction pipe. A switch, also electrically connected to the circuit board, is located on the main unit. When using the product, the user places the suction pipe inside the oil container and the discharge pipe in the new container to be filled. By turning on the switch, the circuit board drives the pump body to operate, drawing oil from the oil container and transferring it sequentially through the suction pipe and discharge pipe into the new container.

[0003] However, currently available portable oil pumps can only be turned on and off using a switch. The oil inlet and outlet of the oil pipe are some distance apart, and the outlet pipe is prone to shaking during the pump's operation. Users need to fix the outlet pipe in place, which makes it inconvenient for them to operate the switch. Especially when filling a new container with oil, the shaking of the outlet pipe can easily cause oil to spill, thus affecting the user experience. Utility Model Content

[0037] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0038] See attached document Figure 1-9 A portable oil pump is described in this embodiment of the present invention.

[0039] The portable oil pump includes a main unit 1, an oil suction pipe 2, a pump body 5, an oil outlet pipe 3, and a control handle 4. The main unit 1 is equipped with a circuit board 7 and a battery 6 electrically connected to the circuit board 7. The oil suction pipe 2 is connected to the main unit 1, and the pump body 5 is disposed inside the oil suction pipe 2 and electrically connected to the circuit board 7. The oil outlet pipe 3 communicates with the oil suction pipe 2. When the pump body 5 is driven, it draws oil and outputs it through the oil suction pipe 2 and then through the oil outlet pipe 3. The control handle 4 is located at the end of the oil outlet pipe 3 furthest from the oil suction pipe 2. The control handle 4 includes: an oil passage pipe 42 with an oil delivery channel 420, an operating element 41 movably disposed on the oil passage pipe 42, and a valve structure connected to the operating element 41. The valve structure is at least partially disposed within the oil delivery channel 420. In the initial state, the valve structure closes the oil delivery channel 420; when the user operates the operating element 41, the valve structure opens the oil delivery channel 420.

[0040] This invention features a control handle 4 mounted on the oil outlet pipe 3, with an operating element 41 and a valve structure on the handle 4. When the user starts the pump body 5, the valve structure closes the oil delivery channel 420 without the operating element 41 being operated, preventing oil from flowing from the oil outlet pipe 3. When oil is needed, the valve structure opens the oil delivery channel 420 by operating the operating element 41, cooperating with the pump body 5 to allow oil to flow from the oil outlet pipe 3. This allows the user to directly control the oil flow from the oil outlet pipe 3 via the control handle 4, making it convenient for the user and preventing oil spillage caused by the oil outlet pipe 3 not being properly secured when the pump body 5 is operating.

[0041] Specifically, the main unit 1 is equipped with a switch 11 that is electrically connected to the circuit board 7 for controlling the operation of the pump body 5. The user can turn the pump body 5 on or off by operating the switch 11. The pump body 5 is connected to the circuit board 7 by a wire. The wire passes through the oil outlet pipe 3 and enters the main unit 1 to connect with the circuit board 7. The wire and the main unit 1 can be sealed by applying glue or interference fit. The electrical connection between the wire and the pump body 5 can be sealed by applying glue.

[0042] In one embodiment, the valve structure includes a piston 45 and an elastic element 44. The piston 45 is at least partially placed within the oil delivery channel 420. Both ends of the elastic element 44 abut against the inner walls of the piston 45 and the oil delivery pipe 42, respectively. The piston 45 is connected to the operating element 41. When the operating element 41 is operated, the piston 45 opens the oil delivery channel 420, cooperating with the pump body 5 to control the oil delivery from the oil outlet pipe 3. At this time, the elastic element 44 is in a compressed state. After the operating element 41 is released, the restoring force of the elastic element 44 can drive the piston 45 back to its initial position, i.e., the piston 45 blocks the oil delivery channel 420, closing the oil delivery channel 420, thus facilitating user control of the oil delivery and user convenience. Of course, in other embodiments, the valve structure may not include the elastic element 44, and the piston 45 may be restored to its initial position by the user operating the operating element 41.

[0043] In an embodiment with piston 45 and elastic member 44, the valve structure further includes a baffle 47 disposed within the oil delivery channel 420. The baffle 47 has an oil passage hole 470. In the initial state, piston 45 closes the oil passage hole 470. When operating member 41 is activated, operating member 41 can drive piston 45 to move and open oil delivery channel 420. The baffle 47, with the oil passage hole 470, is used to accommodate piston 45 and elastic member 44, reducing the volume of piston 45. Of course, in other embodiments, the valve structure may not include baffle 47; piston 45 itself can cover the cross-section of oil delivery channel 420 in the initial state, thus achieving initial closure of oil delivery channel 420.

[0044] In an embodiment with partition 47, partition 47 includes a first plate 473, a second plate 472, and a third plate 471 connected sequentially from top to bottom. One end of both the first plate 473 and the third plate 471 is connected to the inner wall of the oil passage 42, and the oil passage hole 470 is located on the second plate 472. The piston 45 is located on the side of the second plate 472 away from the third plate 471, or the piston 45 is located on the side of the second plate 472 away from the first plate 473, so that the piston 45 can cooperate with the oil passage hole 470.

[0045] Specifically, piston 45 is located on the side of second plate 472 away from third plate 471. Second plate 472 extends along the oil outlet direction, and piston 45 is located on the side of second plate 472 away from operating member 41. A first rod 452 is provided on piston 45. The first rod 452 passes through oil passage 470 and oil pipe 42 in sequence and connects to or abuts against operating member 41. Elastic member 44 is located at the end of piston 45 away from first rod 452. When the user presses the piston, piston 45 is moved away from operating member 41, thus opening oil passage 470 and allowing oil to flow from oil pipe 3. The first plate 473 and third plate 471 are both perpendicular to or at a certain angle to the second plate 472. Of course, in other embodiments, the piston 45 may also be located on the side of the second plate 472 away from the first plate 473. The first rod 452 passes through the oil pipe 42 and is connected to or abuts against the operating member 41. The elastic member 44 is located at the end of the piston 45 near the first rod 452. That is, when the user pulls the operating member 41 in a direction away from the second plate 472, the oil hole 470 can be opened and the elastic member 44 is compressed. When the user releases the operating member 41, the elastic member 44 can drive the piston 45 and the operating member 41 to return to their initial positions.

[0046] In the embodiment where the piston 45 is located on the side of the second plate 472 away from the third plate 471, the sidewall of the oil pipe 42 has an installation port 427 near the elastic member 44. The oil pipe 42 is provided with a cover 43 at the installation port 427. The two ends of the elastic member 44 abut against the cover 43 and the piston 45 respectively, so that the piston 45 and the elastic member 44 can be installed in the oil delivery channel 420.

[0047] In one embodiment, the cover 43 is detachably connected to the oil pipe 42 so that the cover 43 can be installed after the piston 45 and the elastic element 44 are installed in the oil delivery channel 420.

[0048] Specifically, the oil pipe 42 protrudes outward from the periphery of the corresponding mounting port 427 to form a raised enclosure 421. A first thread 422 is provided on the inner side wall of the raised enclosure 421, and a second thread 431 adapted to the first thread 422 is provided on the outer side wall of the cover 43, thereby enabling a detachable connection between the cover 43 and the oil pipe 42. A first rubber ring 432 for sealing is provided between the cover 43 and the raised enclosure 421 to prevent oil leakage from the mounting port 427. Of course, in other embodiments, the cover 43 can also be detachably connected to the oil pipe 42 using a snap-fit ​​mechanism; the detachable structure is not limited here.

[0049] In one embodiment, the piston 45 has a second rod 451 at one end near the elastic member 44, and the cover 43 has a first limiting post 432 at one end near the elastic member 44. The first limiting post 432 has a first limiting hole 433, and the second rod 451 is at least partially placed in the first limiting hole 433 in the initial state. The elastic member 44 is a spring, and both the second rod 451 and the first limiting post 432 are placed inside the spring to limit the spring. The length of the first limiting hole 433 is greater than the stroke of the piston 45 to prevent the movement of the piston 45 from being restricted by the second rod 451 and the first limiting hole 433. Of course, in other embodiments, the cover 43 and the piston 45 have embedding grooves at the corresponding spring positions, and the two ends of the spring are respectively placed in the embedding grooves on the cover 43 and the piston 45, which can also limit the spring. Moreover, the elastic member 44 may not be a spring, but may be a reciprocating folding spring sheet, etc.

[0050] In one embodiment, a second rubber ring 453 is provided on the outer side wall of the piston 45 to seal the oil passage 470 in the initial state, so as to prevent oil from leaking out from the gap between the sealing hole and the piston 45.

[0051] In one embodiment, the oil pipe 42 protrudes outward on the side away from the cover 43 to form a second limiting post 424. A second limiting hole 426 is provided on the second limiting post 424. The first rod 452 passes through the second limiting hole 426, and a third rubber ring 454 for sealing is provided between the first rod 452 and the second limiting hole 426. The length of the second limiting hole 426 is greater than the stroke of the piston 45 to prevent the third rubber ring 454 from dislodging from the second limiting hole 426 and causing oil leakage when the piston 45 moves, causing the first rod 452 to move.

[0052] In one embodiment, the operating member 41 is in the shape of a long strip plate, and the operating member 41 is rotatably connected to the oil pipe 42 on one side of the first rod body 452 so as to be used for operating the operating member 41.

[0053] In one embodiment, the operating member 41 is rotatably connected to the oil passage pipe 42 via a shaft 46. The oil passage pipe 42 has a rotating protrusion 425 on the side of the first rod 452 away from the main unit 1. The operating member 41 has a second limiting groove 412 and shaft holes 411 on both sides of the second limiting groove 412. The rotating protrusion 425 is placed in the second limiting groove 412. The shaft 46 passes through the shaft holes 411 and the rotating protrusion 425 to achieve a rotatable connection between the operating member 41 and the oil passage pipe 42. When the user presses the operating member 41 to a position on the side of the first rod 452 away from the rotating protrusion 425, the first rod 452 can drive the piston 45 away from the operating member 41 to open the oil passage hole 470 and realize oil output from the oil outlet pipe 3.

[0054] In one embodiment, one end of the oil outlet pipe 3 is sleeved on the oil passage pipe 42, and a clamping ring 8 is sleeved on the outer wall of the oil outlet pipe 3 at the position corresponding to the oil passage pipe 42. The clamping ring 8 can improve the stability of the connection between the oil outlet pipe 3 and the oil passage pipe 42.

[0055] Specifically, the outer wall of the oil passage pipe 42 is provided with several locking grooves 423, and the inner wall of the clamping ring 8 is provided with clamping protrusions 81 corresponding to the positions of the locking grooves 423. The clamping protrusions 81 are interference-fitted with the outer wall of the oil outlet pipe 3 to press part of the oil outlet pipe 3 into the locking grooves 423, so as to effectively improve the stability of the connection between the oil outlet pipe 3 and the oil passage pipe 42.

[0056] In one embodiment, the circuit board 7 is located at the end of the battery 6 away from the oil extraction pipe 2, and the switch 11 is located on the end face of the main unit 1 away from the oil extraction pipe 2, so as to avoid the switch 11 affecting the user's grip on the main unit 1 when the main unit 1 is used as a user handle.

[0057] In one embodiment, the main unit 1 is provided with a power interface 12 for connecting to an external power source. The power interface 12 is electrically connected to the circuit board 7, and the battery 6 is a rechargeable battery 6. By connecting to an external power source through the power interface 12, the battery 6 can be charged via the circuit board 7, thereby improving the service life of the portable oil pump in this embodiment.

[0058] In one embodiment, the battery 6 is a dry cell battery. The main unit 1 has a removable battery cover at the position corresponding to the dry cell battery, so that when the battery 6 is depleted, the battery cover can be removed for easy replacement by the user. Specifically, in this embodiment, there are two batteries 6, arranged sequentially away from the oil extraction pipe 2. In this state, the height of the main unit 1 is relatively high. The main unit 1 and the oil extraction pipe 2 are integrated, and the outer wall of the main unit 1 is easy for the user to hold, so that the user can insert the oil extraction pipe 2 into the oil container. The main unit 1 also makes it easy for the user to pick up the product, making it convenient for the user to use. Of course, in other embodiments, the number of dry cell batteries can also be one, three, four, etc., and when there are multiple dry cell batteries, they can be arranged side by side, etc.
