Description

Technical Field

[0001] This utility model relates to an engine oil reservoir, belonging to the field of engine technology. Background Technology

[0002] Currently, in small air-cooled engine products, the traditional oil tank structure usually consists of several parts, including an oil tank cap, a diesel filter element, an oil tank body, an oil tank switch, and an oil tank outlet. For example, Chinese patent application publication number CN111365308A discloses a hydraulic oil tank and a hydraulic oil tank disclosed in an excavator. This oil tank structure is mainly used to store oil and provide power oil for the engine. The filter element is used to filter impurities in the fuel and provide clean fuel for the engine. However, diesel fuel usually contains a certain amount of water, and this type of fuel can structure cannot effectively separate oil and water. Furthermore, the installation of the diesel filter element requires skilled personnel. The filter element must be inserted from the top of the fuel can into the mounting hole at the bottom. Careful alignment is crucial during assembly; otherwise, the filter element may fall into the fuel can and be difficult to remove. Additionally, the fuel can switch and other small components are connected to the fuel filter element below it. These components are secured with bolts, ensuring a tight connection between the fuel filter element and the fuel can switch. Due to the large number of parts in this assembly, consistent quality control during production is difficult. In actual use, the rotary knob of the fuel can switch frequently leaks oil. Summary of the Invention

[0003] The technical problem to be solved by this utility model is to overcome the defects of the prior art and provide an engine oil reservoir that effectively separates oil and water in the reservoir and is easy to use.

[0006] The filter element is used to drain the oil from the oil chamber after it passes through the filter element.

[0007] Furthermore, in order to improve the ease of installation of the filter element and avoid oil leakage, a accommodating partition wall is formed inside the outer shell. The accommodating partition wall covers the filter element and forms a filter cavity. The accommodating partition wall is provided with a first inlet that communicates with the filter cavity. The oil in the oil cavity is suitable to enter the filter cavity through the first inlet.

[0010] The wall surface of the oil-water separation chamber, which is close to and faces the second inlet, is an inclined surface that facilitates flow guidance.

[0011] Furthermore, in order to effectively separate oil and water, the upper end of the oil-water separation chamber is provided with an opening, which is connected to the oil chamber, and the first inlet is connected to the upper side of the oil-water separation chamber.

[0012] Furthermore, the filter element is installed above or to the side of the oil-water separation chamber.

[0029] To make the contents of this utility model easier to understand, the present utility model will be further described in detail below with reference to specific embodiments and accompanying drawings.

[0030] Example 1

[0031] like Figure 1 , 2 As shown, in order to achieve oil-water separation and effectively remove impurities from the oil reservoir, thus preventing malfunctions of related precision parts, an engine oil reservoir includes:

[0032] The kettle body includes an outer shell 1, an oil cavity 11 is formed inside the outer shell 1, an oil-water separation cavity 12 is formed at the bottom of the oil cavity 11 and is connected to the oil cavity 11, and a water outlet 13 is also provided on the outer shell 1 and is connected to the oil-water separation cavity 12.

[0033] The oil in the oil chamber 11 is suitable for being discharged after passing through the filter element 2.

[0034] Specifically, if Figure 1 , 2 As shown, the drain outlet 13 is located on the side of the wall of the oil-water separation chamber 12.

[0035] Specifically, if Figure 1 , 2 As shown, in order to facilitate the drainage of water from the oil-water separation chamber 12, the drain outlet 13 is located at the lowest point on the side of the chamber wall of the oil-water separation chamber 12.

[0036] Specifically, if Figure 1 , 2 As shown, the engine oil reservoir also includes an oil reservoir cap 3, and an oil inlet connected to the oil chamber 11 is formed on the outer shell 1. The oil reservoir cap 3 covers the oil inlet.

[0037] Specifically, if Figure 1 , 2 As shown, a filter element 4 is provided on the oil inlet; in this embodiment, the filter element 4 is a primary filter screen.

[0038] In this embodiment, as Figure 1 , 2 As shown, the oil-water separation chamber 12 can be set on one side of the pot body, or it can be set on both sides of the pot body. The oil-water separation chamber 12 can be an integral structure with the pot body, or it can be a separate device structure attached to the pot body.

[0039] This embodiment utilizes the internal structure of the oil reservoir, designing one or more integrated oil-water separation chambers 12 on one, two, or multiple locations on the bottom surface inside the outer shell 1. The oil-water separation chambers 12 are positioned at a lower level relative to the overall structure of the oil reservoir. When the diesel engine is running or the reservoir is filled with oil, the water in the fuel, being denser than fuel, will automatically settle into the oil-water separation chambers 12 under gravity, thus achieving oil-water separation. Simultaneously, some impurities within the fuel will also be collected into the oil-water separation chambers 12 under gravity. Once the internal water level reaches a certain point or the reservoir is full, the drain port 13 on the oil-water separation chambers 12 can be opened to release the water and impurities.

[0040] Example 2

[0041] like Figure 3 , 4As shown, the engine oil reservoir of this embodiment, based on the structure of the oil-water separation chamber 12 in Embodiment 1, also has the following structure: In order to improve the ease of installation of the filter element 2 and avoid oil leakage, a accommodating partition wall 14 is formed inside the outer shell 1. In this embodiment, the accommodating partition wall 14 includes a shell wall 14a formed by an outward indentation at the bottom of the outer shell 1 and a baffle wall 14b formed above the filter element 2.

The oil in the oil cavity 11 is suitable to enter the filter cavity 14c through the first inlet 14d.

[0042] In this embodiment, as Figure 3 As shown, filter element 2 is installed on the side of oil-water separation chamber 12.

The oil above the oil-water separation chamber 12 enters the filter element 2 through the first inlet 14d, is filtered by the filter element 2, and is discharged through the oil outlet 16.

[0047] Specifically, the filter element 2 can be installed in the following two ways: The first way is that the filter element 2 is integrally formed with the outer shell 1. During the forming process of the outer shell 1, the filter element 2 is placed in the recessed cavity in advance and formed together with the outer shell 11; The second way is that after the outer shell 1 is formed, the outer shell 1 is provided with a filter element installation hole. A cover is installed on the filter element 2 installation hole. The filter element 2 enters through the filter element installation hole and is assembled in the outer shell 1. The cover is connected to the filter element installation hole after the filter element 2 is installed in place.
