[0023] Embodiment one

[0024] A blending device for lubricating oil: comprising: a shell 1 and a top cover 2, the top cover 2 is installed with the stirring structure for the lubricating oil blending inside the shell 1, the top cover 2 is clamped to the shell 1, the shell 1 is closed by the top cover 2, a through hole is formed in one side of the top cover 2, a bidirectional fan 33 is installed in the through hole, the bidirectional fan 33 rotates the impeller by the motor to generate a certain air volume and air pressure, so that the purpose of exhausting or taking in air is achieved, an auxiliary assembly 3 is installed at the top of the through hole, the auxiliary assembly 3 has a rotary alternating first replacement frame 31 and a second replacement frame 35, the inner wall of the first replacement frame 31 is a baffle 32, the first replacement frame 31 and the second replacement frame 35 are connected through the connecting part corresponding to the shaft body of the rotary motor 34.

[0025] Under normal conditions, the first replacement frame 31 is driven by the rotary motor 34 to correspond to the through hole, and then the baffle 32 of the first replacement frame 31 forms a closure to the through hole, thereby maintaining the relative closure of the shell 1.

[0026] The bottom of the top cover 2 is installed with a humidity sensor 12 and an air content sensor 13, the inner wall of the second replacement frame 35 is a filter element 36 that can absorb moisture;

[0027] The resistance type humidity sensor 12 measures the change of the resistance value of the humidity-sensitive material with the humidity, when the environmental humidity increases, the humidity-sensitive material absorbs water, which causes the resistance value to decrease, by measuring the change of the resistance, the current humidity value can be calculated.

[0028] The working principle of the air sensor is to measure the absolute pressure in the air inlet pipe to know the air density, and then calculate the air intake combined with the engine speed.

[0029] When the humidity sensor 12 detects that the humidity exceeds the threshold value, the second replacement frame 35 is rotated to correspond to the through hole by the rotary motor 34.

[0030] The air content sensor 13 is connected to the control signal end of the bidirectional fan 33.

[0031] When the air content detected by the air content sensor 13 exceeds the threshold value, the bidirectional fan 33 reverses to draw air outward.

[0032] When the air content detected by the air content sensor 13 is lower than the threshold value, the bidirectional fan 33 rotates to blow air inward.

[0033] The humidity sensor 12 detects the humidity in the shell 1. When the humidity is too high, it will affect the finished product effect of the lubricating oil. When the detected humidity exceeds the threshold value, the rotating motor 34 is started to make the first replacement frame 31 and the second replacement frame 35 not correspond to the through hole, and the bidirectional fan 33 reverses to draw the humid air inside outward, thereby controlling the humid air evaporated during the blending process of the lubricating oil.

[0034] During the blending process of the lubricating oil, a certain amount of air is needed for reaction. When the air content sensor 13 detects that the air content is low, the rotating motor 34 is started to make the second replacement frame 35 correspond to the through hole, and the bidirectional fan 33 is started to rotate to blow air inward. The external air is filtered by the filter element 36 to avoid increasing the humidity inside the shell 1 when the air is supplemented, and to maintain the humidity and air content during the blending process of the lubricating oil.

The stirring motor 4 is installed on the top of the top cover 2, and the shaft of the stirring motor 4 is connected with the stirring part 41.

[0036] Preferably, the other side of the top cover 2 is provided with a feeding port 11. The lubricating oil and the auxiliary materials can be added into the shell 1 through the feeding port 11.

[0037] The bidirectional fan 33 rotates to blow air and reverses to draw air. The signal output end of the air content sensor 13 is connected to the control signal end of the bidirectional fan 33.

[0038] When the air content in the shell 1 is low, the bidirectional fan 33 rotates to blow air inward to supplement air.

[0039] When the air content in the shell 1 is high, the bidirectional fan 33 reverses to draw air outward.

[0040] Specific working principle:

[0041] The top cover 2 is clamped to the shell 1, lubricating oil and auxiliary materials can be added into the shell 1 through the feeding port 11, and the lubricating oil and the auxiliary materials in the shell 1 are mixed by the stirring part 41 driven by the stirring motor 4;

[0042] In the normal state, the first replacement frame 31 is driven by the rotating motor 34 to correspond to the through hole, and then the baffle 32 of the first replacement frame 31 forms a closed state with the through hole, thereby keeping the relative sealing of the shell 1;

[0043] The humidity sensor 12 detects the humidity in the shell 1, and the high air humidity will affect the finished product effect of the lubricating oil; when the detected humidity exceeds the threshold value, the rotating motor 34 is started to make the first replacement frame 31 and the second replacement frame 35 not correspond to the through hole, and then the bidirectional fan 33 is reversed to exhaust the internal humid air;

[0044] When the air content sensor 13 detects that the air content is low, the rotating motor 34 is started to make the second replacement frame 35 correspond to the through hole, and then the bidirectional fan 33 is started to blow air inward, and the external air is filtered by the filter element 36 to avoid increasing the humidity in the shell 1 when the air is supplemented, and to keep the humidity and air content in the lubricating oil mixing process.
