[0022] The following will describe the present utility model in detail with reference to the accompanying drawings. The embodiments of the present utility model will be described in detail below. The examples of the embodiments are shown in the drawings, where the same or similar reference numerals represent the same or similar elements or elements with the same or similar functions throughout. The embodiments described by referring to the drawings below are exemplary and are only used to explain the present utility model, and should not be construed as a limitation to the present utility model. The orientation terms such as left, middle, right, up, and down in the embodiments of the present utility model are only relative concepts to each other or are referenced based on the normal use state of the product, and should not be considered restrictive.

[0023] First Embodiment:

[0024] A new type of suction filter, as Figure 1 and Figure 2 shown, includes a body for filtering oil fluid. The body is formed by docking an upper housing 1 and a lower housing 2. A filter layer 4, an oil filtering chamber 200, and an oil outlet chamber 100 are provided in the body. The oil outlet chamber 100 is formed by the space between the filter layer 4 and the upper housing 1. Two oil outlet ports 11 communicating with the oil outlet chamber 100 are provided on the upper housing 1. The oil outlet ports 11 are located at the positions on the body corresponding to the oil outlet chamber 100 and are directly communicated with the oil outlet chamber 100. The oil filtering chamber 200 is formed by the space between the filter layer 4 and the lower housing 2. Support columns 3 are integrally provided at the positions corresponding to the filter layer 4 in the upper housing 1 and the lower housing 2. The support columns 3 are used to be close to or in contact with the filter layer 4, so as to limit the position of the filter layer 4 in the body. The right end of the body is a flat part, and the thickness of the flat part is less than the thickness of the left end of the body. An oil inlet passage 201 is provided in the flat part. The oil inlet passage 201 and the oil filtering chamber 200 are arranged side by side left and right in the body (referring to the left and right directions of the body in Figure 1 and are communicated with each other. The oil inlet passage 201 is communicated with an oil inlet 21 provided on the lower housing 2 at the flat part. The opening direction of the oil inlet 21 is downward. The oil outlet chamber 100 is located on the left side of the body, so that the oil fluid is discharged from the body after passing through the oil inlet 21, the oil inlet passage 201, the oil filtering chamber 200, the filter layer 4, the oil outlet chamber 100, and the oil outlet ports 11 in sequence.

[0025] Wherein, for the convenience of forming the oil inlet passage 201, the filter layer 4 is formed by filter paper with a planar structure. The filter layer 4 is clamped between the upper housing 1 and the lower housing 2, that is, the edge of the filter layer 4 matches the edges of the upper housing 1 and the lower housing 2 and is hermetically and fixedly connected to the welds of the upper housing 1 and the lower housing 2. Both the oil filtering chamber 200 and the oil inlet passage 201 are formed by the filter layer 4 and the lower housing 2.

[0026] The upper housing 1 at the flat part can be close to or in contact with the filter layer 4. In this embodiment, a part of the upper housing 1 at the flat part is attached to the filter layer 4, so as to control the thickness of a part of the flat part within the minimum range.

[0027] Second embodiment:

[0028] Other technical features are the same as those of the first embodiment. Figure 3 As shown, in order to increase the filtering area, the right end of the filter layer 4 is a flat structure (with Figure 1 The left and right directions of the middle body are used as a reference), specifically a planar structure, the left end of the filter layer 4 is a wave-shaped structure that undulates up and down, and the outer edge of the filter layer 4 is sealed and fixedly connected with a connecting portion 41 made of rubber. The connecting portion 41 is preferably nylon plastic, and a skirt 43 is provided on the edge of the connecting portion 41. The skirt 43 matches the edges of the upper shell 1 and the lower shell 2 and is sealed and fixedly connected to the weld of the upper shell 1 and the lower shell 2, so that the filter layer 4 is sealed and set between the upper shell 1 and the lower shell 2.

[0029] Third embodiment:

[0030] Other technical features are the same as those of the first embodiment. In some application scenarios, the thickness of the flat portion needs to be controlled to be very small. When the filter layer 4 is arranged in the flat portion, the utilization rate of the filter layer 4 is not high. In order to reduce the waste of the filter layer 4, the filter layer 4 is combined with the filter layer 4 to reduce the waste of the filter layer 4. Figure 4 As shown, a partition plate 42 is sealed and fixedly connected to the left side of the filter layer 4, the filter cavity 200 is formed by the filter layer 4 and the lower shell 2, and the oil inlet channel 201 is formed by the partition plate 42 and the lower shell 2. In order to increase the filtering area, the filter layer 4 is formed by folding the filter paper, and the outer edge of the filter layer 4 is sealed and fixedly connected to a nylon plastic connecting portion 41, and the edges of the connecting portion 41 and the partition plate 42 are both provided with a skirt 43, which matches the edges of the upper shell 1 and the lower shell 2 and is sealed and fixedly connected to the weld of the upper shell 1 and the lower shell 2, so that the filter layer 4 and the partition plate 42 are sealed and arranged between the upper shell 1 and the lower shell 2. The upper shell 1 at the flat part is close to or in contact with the partition plate 42. In this embodiment, the part of the upper shell 1 at the flat part fits the partition plate 42, so that the thickness of a part of the flat part is controlled to be within the minimum range.

[0031] Fourth embodiment:

[0032] Other technical features are the same as those of the first embodiment, such as Figure 5 As shown, the oil inlet channel 201 is formed by an upper shell 1 and a lower shell 2, a sealing assembly 5 is provided in the middle of the upper shell 1 corresponding to the side of the filter layer 4, the corresponding side of the filter layer 4 is sealed and fixedly connected to the upper shell 1 through the sealing assembly 5, the other side of the filter layer 4 is clamped between the upper shell 1 and the lower shell 2, and the oil outlet chamber 100 is formed by the filter layer 4, the upper shell 1 and the sealing assembly 5.

[0033] Among them, the sealing assembly 5 includes a base 52 and a gland 51. The base 52 is integrally connected to the upper housing 1. The base 52 and the gland 51 are clamped on the side edge of the filter layer 4 and fit against each other. The gland 51 is fixedly connected to the base 52. To increase the sealing performance between the base 52, the gland 51 and the filter layer 4, a receiving groove is formed on the table surface of the base 52. The side edge of the filter layer 4 is folded to form a folded portion, and the folded portion is inserted into the receiving groove. The gland 51 presses on the side edge of the filter layer and makes the folded portion abut against the bottom surface of the receiving groove.

[0034] Fifth Embodiment:

[0035] In the case where other technical features are the same as those in the first embodiment, as Figure 6 shown, an oil baffle 6 is integrally provided on the upper housing 1, and the oil baffle 6 is located at the flat portion; the oil baffle 6 is an arc extending from top to bottom and is a groove structure, and the left and right sides and the upper side of the groove structure are all open structures. During installation, as Figure 7 shown, the flat portion is placed between the gear 8 and the bottom surface of the oil pan 7, and at the same time, the oil baffle 6 covers the lower side of the gear 8.

[0036] The above shows and describes the basic principles, main features and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited by the above embodiments. What is described in the above embodiments and the specification only illustrates the principle of the present invention.
