Detailed Description

The following detailed description of the present invention is provided in conjunction with the accompanying drawings, but it should be understood that the scope of the present invention is not limited to the specific embodiments.

Throughout the specification and claims, unless explicitly stated otherwise, the word "comprise", or variations such as "comprises" or "comprising", will be understood to imply the inclusion of a stated element or component but not the exclusion of any other element or component.

As shown in fig. 1, the oil cover structure according to an embodiment of the present invention includes an oil cover body 2 and an oil cover upper cover 3 provided on the oil cover body 2.

As shown in fig. 1 to 3, in a specific embodiment, the oil cap body 2 may be disposed on the oil can body 1, a containing cavity 11 and an oil inlet 12 are disposed in the oil can body 1, fuel oil may be placed in the containing cavity 11, and the oil cap body 2 is screwed on the oil can body 1 and located at the oil inlet 12, so as to seal the containing cavity 11 and prevent fuel oil from leaking.

As shown in fig. 2 and 3, in one embodiment, the oil cover body 2 is provided with a vent hole 21, and two ends of the vent hole 21 are respectively communicated with the accommodating cavity 11 and the external environment. When the fuel in the holding cavity 11 is reduced, the air in the environment can enter the holding cavity 11 through the vent hole 21, so that the balance between the air pressure in the holding cavity 11 and the outside is ensured, and the difficulty in oil feeding caused by the reduction of the air pressure in the holding cavity 11 is reduced.

As shown in fig. 5, at least one rib 22 is disposed on the outer side wall of the oil cap body 2, and the rib 22 has an effect that a user can conveniently screw the oil cap body 2 on the oil can body 1 and can conveniently unscrew the oil cap body 2 from the oil can body 1.

As shown in fig. 2 and 3, in an embodiment, the oil cover upper cover 3 may be disposed or covered on the oil cover body 2 at a position of the vent hole 21. Wherein, a ventilation channel 23 is formed between the oil cover upper cover 3 and the oil cover body 2, and the ventilation hole 21 is communicated with the external environment through the ventilation channel 23.

In the above embodiment, the ventilation channel 23 and the ventilation hole 21 cooperate to form a labyrinth-like structure, which lengthens the path of air entering the accommodating chamber 11. When the oil can body 1 inclines or turns over, because the aperture or the cross-sectional area of the labyrinth-like structure is smaller and the path is longer, the fuel enters the space of the labyrinth-like structure and stays in the labyrinth-like structure under the action of the surface tension of the liquid, so that the possibility that the fuel in the accommodating cavity 11 leaks out of the oil can body 1 is reduced.

Meanwhile, the range of the air-permeable passage 23 contacting the environment is larger and dispersed than the range of the air-permeable hole 21 contacting the environment, and thus the possibility of being clogged by the wood chips in the environment or impurities in the environment is greatly reduced.

As shown in fig. 2 and 3, in an embodiment, a receiving groove 24 recessed downward may be provided above the oil cover body 2, and the oil cover upper cover 3 is at least partially placed in the receiving groove 24, so as to limit and fixedly connect the oil cover upper cover 3.

As shown in fig. 2 to 5, in a specific embodiment, a cylindrical protrusion 25 may be disposed at the bottom of the receiving groove 24 of the oil cover body 2, at least a portion of the vent hole 21 is located in the cylindrical protrusion 25, an extending direction of the vent hole 21 is the same as a height direction of the cylindrical protrusion 25, a groove 32 is disposed on a side of the oil cover upper cover 3 facing the oil cover body 2, a height of the cylindrical protrusion 25 is greater than a depth of the groove 32, and when the oil cover upper cover 3 is connected to the oil cover body 2, the groove 32 and the cylindrical protrusion 25 are in interference fit. The cylindrical projection 25 is matched with the groove 32, and plays a role in clamping the oil cover upper cover 3 on the oil cover body 2.

As shown in fig. 4, in one embodiment, the bottom and the side wall of the groove 32 are concavely formed with a ventilation groove 33, and at least one end of the ventilation groove 33 is communicated with the air through the ventilation channel 23. The ventilation groove 33 is respectively communicated with one end of the ventilation hole 21 and the ventilation channel 23, and the ventilation groove 33 plays a role of connecting the ventilation hole 21 with the ventilation channel 23.

As shown in fig. 2 and 3, the oil can body 1 may further be provided with a check valve 13 near the oil inlet 12. And functions to prevent fuel from leaking from the accommodating chamber 11.

As shown in fig. 2 and 3, a vent column 26 may be further disposed below the oil cover body 2, at least a portion of the vent column 26 is in interference fit with the check valve 13, and a portion of the vent hole 21 is located in the vent column 26 and is communicated with the check valve 13. The vent post 26 cooperates with the check valve 13 to ensure that the vent hole 21 is in communication with the check valve 13.

As shown in fig. 1, an oil can according to an embodiment of the present invention is provided with the oil cap structure described above.

As shown in fig. 2, 3 and 6, in one embodiment, the oil can is mounted on a power tool 4 or an electric device, the power tool 4 may be a chain saw, and is provided with an oil pump 41 and an oil inlet pipe 42, and the oil pump 41 is communicated with the bottom of the oil can body 1 through the oil inlet pipe 42. Wherein, the oil pump 41, the oil inlet pipe 42 and the oil pot are matched for use, and can play a role in pumping oil.

In one embodiment, the oil cap body and the oil cap upper cover of the present embodiment can be used not only for oil cans or other oil cans, but also for cases containing other types of liquids, and can achieve the same ventilation and prevent liquid leakage.

In summary, in the oil can and the chain saw of the present invention, the oil cap upper cover 3 is configured to be connected to the oil cap body 2 to partially close the oil cap body 2, wherein the inside surface of the oil cap upper cover 3 is provided with the ventilation groove 33, when the oil cap upper cover 3 is connected to the oil cap body 2, the ventilation groove 33 is communicated with the ventilation hole 21, and at least one end of the ventilation groove 33 is communicated with air, so as to form a labyrinth structure in combination, which not only satisfies the effect that air can enter the oil can body 1 and is not easily blocked by wood chips or impurities in the environment, but also better prevents fuel oil from leaking from the oil cap structure.
