[0026] The present invention will be further described below with reference to the accompanying drawings:

[0027] Example 1: Figures 1-3 As shown, a new oil pan structure for a sewing machine includes a shell 1, an oil storage chamber 9 is provided on the mounting surface of the shell 1, an oil drain hole 6 connected to the oil storage chamber 9 is provided on the side wall of the shell 1, a first guide plate 3, a second guide plate 4 and a third guide plate 5 are provided in the oil storage chamber 9, the first guide plate 3 and the second guide plate 4 are located on one side of the third guide plate 5, the first guide plate 3 is located between the second guide plate 4 and the oil drain hole 6, the first guide plate 3 and the third guide plate 5 are parallel to each other, and one end of the first guide plate 3 is connected to the second guide plate 4.

[0028] Specifically, the second flow guide plate 4 includes a long plate 42, a short plate 41 and an arc-shaped plate 43, the long plate 42 is perpendicular to the first flow guide plate 3, the short plate 41 is parallel to the first flow guide plate 3 and the third flow guide plate 5, one end of the arc-shaped plate 43 is connected with the long plate 42, and the other end is connected with the short plate 41, the first flow guide plate 3 is connected with the long plate 42 and / or the arc-shaped plate 43, so that one end of the first flow guide plate 3 is connected with the second flow guide plate 4, and the shape of the second flow guide plate 4 is adjusted to limit the flow direction of the lubricating oil, so that the lubricating oil in the oil storage cavity 9 can flow in the designed direction.

[0029] Specifically, the number of the first flow guide plate 3 is at least one, and the heat dissipation effect can be improved by the plurality of first flow guide plates 3.

[0030] Specifically, the inner wall of the oil storage cavity 9 at both ends of the third flow guide plate 5 is provided with a flow guide angle, which is a circular arc or an inclined surface, so that the lubricating oil flows more smoothly.

[0031] Specifically, the mounting surface of the shell 1 is provided with a sealing groove 2, the sealing groove 2 is connected end to end and surrounds the oil storage cavity 9 once, which is convenient for installing the sealing ring and sealing the oil storage cavity 9 by cooperating with the sewing machine.

[0032] Specifically, the bottom of the shell 1 is fixedly provided with a plurality of reinforcing ribs 7, which can not only ensure the mechanical strength of the shell 1, but also provide heat dissipation for the lubricating oil in the oil storage cavity 9 of the shell 1.

[0033] Specifically, a plurality of mounting holes 8 are also provided through the shell 1, which is convenient for fixing and installing the shell 1 to the sewing machine.

[0034] Specifically, the material of the shell 1 is aluminum, and the aluminum shell 1 can be integrally cast by casting, which is simple and convenient in production process, and the aluminum shell 1 can also improve the heat dissipation effect of the lubricating oil.

[0035] The working process of the embodiment is as follows: the oil pan of the sewing machine is located at the bottom of the sewing machine, so the sealing ring with the same shape as the sealing groove 2 of the shell 1 is first installed into the sealing groove 2, then the shell 1 is fixed to the corresponding position at the bottom of the sewing machine through the mounting hole 8, the sealing ring in the sealing groove 2 of the shell 1 seals the connection between the shell 1 and the sewing machine to prevent oil leakage, and the lubricating oil is added into the oil storage cavity 9 of the shell 1 through the oil inlet after ensuring that the oil discharge hole 6 is in a sealed state.

[0036] When the shell 1 is installed, the oil suction port of the oil pump is located inside the second flow guide plate 4, and after the sewing machine is powered on, the oil pump will pump out the lubricating oil in the oil storage cavity 9 and deliver it to each rotating part of the sewing machine for lubrication, and the lubricated lubricating oil will then fall into the shell 1, as shown in Figure 4 Under the guidance of the oil passage on the sewing machine, the lubricating oil will fall to the A area on the shell 1, and one end of the first flow guide plate 3 is connected with the long plate 42 and the arc plate 43, and the other end is not connected with the inner wall of the shell 1, so that an open oil groove is formed between two adjacent first flow guide plates 3, therefore the lubricating oil falling into the A area will flow to the open end of the oil groove formed by the two first flow guide plates 3, and part of the lubricated oil will flow out from the two sides of the third flow guide plate 5 into the inside of the second flow guide plate 4 and be pumped out again by the oil pump, and the other part of the lubricating oil will flow through the channel between the first flow guide plate 3 and the side wall of the shell 1, and finally also flow into the second flow guide plate 4 to be pumped out by the oil pump to participate in the lubrication of the sewing machine again, and the lubricating oil flowing back to the shell 1 can be cooled by the contact between the lubricating oil and the first flow guide plate 3 and the third flow guide plate 5 when flowing.

[0037] If it is necessary to replace the lubricating oil in the shell 1 or to transport the sewing machine, in order to avoid the lubricating oil flowing out during transportation and causing pollution, the drain hole 6 can be opened to drain the lubricating oil in the shell 1.

[0038] The above describes one embodiment of the present application in detail, but the above description is only a preferred embodiment of the present application and cannot be considered as limiting the scope of the present application. Any equivalent changes and improvements made within the scope of the present application should still belong to the patent coverage of the present application.
