[0032] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of them. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0033] like Figure 1-3 As shown, the embodiment of the utility model provides an engine oil system for automatically replenishing oil, including an oil storage chamber 1 for storing oil arranged inside an engine case 100, and also including:

[0034] An engine oil tank 2, used for storing engine oil;

[0035] an oil replenishing passage 3, used for the oil tank 2 to replenish the oil into the oil storage chamber 1 when the oil level in the oil storage chamber 1 is lower than a set oil level, and for the oil tank 2 to stop replenishing the oil into the oil storage chamber 1 when the oil level in the oil storage chamber 1 is higher than the set oil level; and

[0036] The air pressure balance channel 4 is used to automatically adjust the air pressure of the oil sump 2 and the oil storage chamber 1 based on the air pressure balance principle during the process of the oil sump 2 replenishing the oil into the oil storage chamber 1, so as to keep the air pressure of the oil sump 2 and the oil storage chamber 1 balanced.

[0037] The working principle of the engine oil system of the utility model for automatically replenishing oil is as follows:

[0038] Add spare oil into the oil tank 2. When the engine is shut down or in use, when the oil level in the oil storage chamber 1 is lower than the set oil level, the oil tank 2 replenishes the oil into the oil storage chamber 1. When the oil level in the oil storage chamber 1 is higher than the set oil level, the oil tank 2 stops replenishing the oil into the oil storage chamber 1. During the process of the oil tank 2 replenishing the oil into the oil storage chamber 1, the air pressure balance channel 4 automatically adjusts the air pressure of the oil tank 2 and the oil storage chamber 1 based on the air pressure balance principle to keep the air pressure of the oil tank 2 and the oil storage chamber 1 balanced.

[0039] To sum up, the present embodiment provides an engine oil system with automatic oil replenishment, and by adding an oil tank 2, an oil replenishment channel 3 and an air pressure balance channel 4, when the oil level in the oil storage chamber 1 is lower than the set oil level, the oil storage chamber 1 can be automatically replenished with oil through the oil tank 2 via the oil replenishment channel 3 based on the air pressure balance principle under the action of the air pressure balance channel 4; when the oil level in the oil storage chamber 1 is higher than the set oil level, the oil tank 2 stops replenishing the oil storage chamber 1 with oil, thereby realizing automatic oil replenishment of the engine, effectively reducing the frequency of manual oil addition by users, and improving the convenience of equipment maintenance.

[0040] In one embodiment, the oil replenishment channel 3 has an oil inlet port 31 and an oil outlet port 32, the oil inlet port 31 of the oil replenishment channel 3 is in communication with the engine oil tank 2, and the oil outlet port 32 of the oil replenishment channel 3 is in communication with the engine oil storage chamber 1;

[0041] The air pressure balance channel 4 has an air outlet port 41 and an air inlet port 42. The air outlet port 41 of the air pressure balance channel 4 is communicated with the engine oil tank 2, and the air inlet port 42 of the air pressure balance channel 4 is communicated with the engine oil storage chamber 1.

[0042] in,

[0043] The oil outlet port 32 of the oil replenishment channel 3 is higher than the oil outlet port 32 of the oil replenishment channel 3, and the oil inlet port 31 of the oil replenishment channel 3 and the air outlet port 41 of the air pressure balance channel 4 are both higher than the air inlet port 42 of the air pressure balance channel 4;

[0044] When the oil level in the oil tank 2 is higher than the higher one of the oil inlet port 31 of the oil replenishment channel 3 and the air outlet port 41 of the air pressure balance channel 4 , the cavity above the oil level in the oil tank 2 can form a closed space.

[0045] In this embodiment, when the engine oil level in the engine oil storage chamber 1 is lower than the air inlet port 42 of the air pressure balance channel 4, the engine oil in the engine oil tank 2 enters the oil replenishment channel 3 through the oil inlet port 31 of the oil replenishment channel 3 under the action of gravity, and flows into the engine oil storage chamber 1 from the oil outlet port 32 of the oil replenishment channel 3 through the oil replenishment channel 3, while the air in the space above the engine oil level of the engine oil storage chamber 1 enters the air pressure balance channel 4 from the air inlet port 42 of the air pressure balance channel 4, and enters the closed space above the engine oil level in the engine oil tank 2 from the air outlet port 41 of the air pressure balance channel 4 through the air pressure balance channel 4 to achieve air pressure balance between the engine oil tank 2 and the engine oil storage chamber 1, and when the engine oil tank 2 replenishes the engine oil to the engine oil storage chamber 1 During the process, the oil level in the oil storage chamber 1 continues to rise. When the oil level in the oil storage exceeds the air inlet port 42 of the air pressure balance channel 4, the air in the oil storage chamber 1 can no longer enter the oil tank 2 from the air pressure balance channel 4. At this time, the interior of the oil tank 2 and the interior of the oil storage chamber 1 are in a state of atmospheric pressure balance. The oil in the oil tank 2 can no longer enter the oil storage chamber 1 through the oil replenishment channel 3. At this time, the oil replenishment is automatically stopped, so that the oil tank 2 dynamically and automatically replenishes the oil into the oil storage chamber to ensure that the oil level in the oil storage chamber 1 (i.e., the engine oil level) is always maintained near the set oil level (i.e., the height corresponding to the air inlet port 42 of the air pressure balance channel 4).

[0046] In one embodiment, the air intake port 42 of the air pressure balance passage 4 is lower than the oil level corresponding to the highest oil level mark on the oil dipstick of the engine, or the air intake port 42 of the air pressure balance passage 4 is flush with the oil level corresponding to the highest oil level mark on the oil dipstick of the engine.

[0047] In this way, the set oil level is lower than the oil level corresponding to the highest oil level scale line of the engine's oil dipstick or is flush with the oil level corresponding to the highest oil level scale line of the engine's oil dipstick, that is, the engine oil level will not exceed the highest oil level scale line of the oil dipstick after automatic oiling, thereby preventing the oil level from being too high after automatic oiling and affecting the engine performance or damaging the engine.

[0048] In one embodiment, the oil outlet port 32 of the oil replenishment channel 3 is lower than the oil level corresponding to the lowest oil level mark of the engine oil dipstick, so that the oil outlet port 32 of the oil replenishment channel 3 can be always submerged by the oil in the oil storage chamber 1, avoiding splashing when replenishing the oil and affecting the accuracy of the oil level in the oil storage chamber 1.

[0049] In one embodiment, the oil inlet port 31 of the oil replenishment channel 3 is arranged at the lowest point of the bottom of the oil tank 2. This arrangement allows the oil in the oil tank 2 to be fully replenished into the oil storage chamber 1 of the oil engine without any residue.

[0050] In one embodiment, a refueling port 21 is provided at the top of the oil tank 2, and a tank cap 22 is threadedly connected to the refueling port 21. A sealing ring (not shown in the figure) is provided inside the tank cap 22. When the tank cap 22 is threadedly connected to the refueling port 21, the refueling port 21 can be sealed. In this way, the oil tank cap 22 can be opened to add oil to the oil tank 2, which improves the convenience of adding oil to the oil tank 2. In addition, after the tank cap 22 is covered, it is convenient to ensure that the refueling port 21 of the oil tank 2 is sealed, thereby ensuring that the space above the oil level in the oil tank 2 forms a closed space, and ensuring the smooth subsequent automatic oil replenishment.

[0051] In one embodiment, the oil replenishment passage 3 and / or the air pressure balance passage 4 include passages opened on the engine case 100 and / or the case of the oil tank 2. In this way, the oil replenishment passage 3 and / or the air pressure balance passage 4 are at least partially opened on the case of the engine case 100 and / or the case of the oil tank 2, reducing the setting of additional pipelines.

[0052] In one embodiment, the oil replenishment channel 3 and / or the air pressure balance channel 4 are pipes connecting the oil storage chamber 1 and the oil tank 2. In this way, the oil storage chamber and the oil tank 2 are connected by a pipe to realize the function of the oil replenishment channel 3 and / or the air pressure balance channel, avoid opening a channel on the engine case 100 and / or the case of the oil tank 2, reduce manufacturing costs, and facilitate the maintenance of the oil replenishment channel 3 and / or the air pressure balance channel 4.

[0053] Specifically, the oil tank 2 can be arranged separately from the engine case 100 (eg Figure 1 , Figure 2 As shown), it is convenient to modify the existing engine and to choose whether to configure the oil tank according to user needs, thereby improving the diversity and adaptability of the product; the oil tank 2 can also be installed and fixed on the engine case 100 (as shown in FIG. Figure 3 As shown) or integrally formed with the engine case 100.
