[0030] Next, the technical solutions of the present utility model will be clearly and completely described in conjunction with the accompanying drawings. Obviously, the described embodiments are some, but not all, of the embodiments of the present utility model. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without creative efforts shall fall within the protection scope of the present utility model.

[0031] The present utility model provides an oil fume monitoring device, and multiple embodiments are given below to describe in detail the oil fume monitoring device provided by the present utility model.

[0032] The oil fume monitoring device provided in this embodiment, as Figures 1 to 5 shown, includes a pipe body 1 and an oil fume monitoring component 2; one end of the pipe body 1 is communicated with the oil fume monitoring component 2, and the other end of the pipe body 1 is used for being communicated with a smoke exhaust passage 3; the axis of the pipe body 1 is inclined with respect to the horizontal plane, and the pipe body 1 is gradually inclined downward from the end communicated with the oil fume monitoring component 2 to the end communicated with the smoke exhaust passage 3.

[0033] After the oil fume in the smoke exhaust passage 3 enters the pipe body 1 from the end of the pipe body 1 communicated with the smoke exhaust passage 3, it flows obliquely upward towards the end of the pipe body 1 communicated with the oil fume monitoring component 2, and then enters the oil fume monitoring component 2. After the oil fume monitoring component 2 detects the oil fume concentration, the oil fume is discharged to the outside of the oil fume monitoring component 2.

[0034] Since the pipe body 1 gradually slopes downward from the end connected to the oil fume monitoring component 2 to the end connected to the smoke exhaust passage 3, after the water vapor and tiny oil droplets in the oil fume condense in the pipe body 1, they will flow towards the end of the pipe body 1 connected to the smoke exhaust passage 3 and finally flow into the smoke exhaust passage 3. This can prevent the accumulation of water vapor and tiny oil droplets in the pipe body 1, reduce the influence of water vapor on the oil fume monitoring component 2, improve the monitoring accuracy of the oil fume monitoring component 2, reduce the accumulation speed of oil droplets in the pipe body 1, lower the probability of blockage of the pipe body 1, and extend the maintenance cycle of the oil fume monitoring device.

[0035] Specifically, the end of the pipe body 1 connected to the oil fume monitoring component 2 is located above the end of the pipe body 1 connected to the smoke exhaust passage 3. After the water vapor and tiny oil droplets condense in the pipe body 1, under the action of their own gravity, they will flow towards the lower position, so that the condensed water vapor and tiny oil droplets flow into the smoke exhaust passage 3, preventing the accumulation of water vapor and tiny oil droplets in the pipe body 1 and also preventing water vapor and tiny oil droplets from entering the oil fume monitoring component 2.

[0036] The axis of the pipe body 1 can be an arc or a straight line or any other suitable form.

[0037] Preferably, the axis of the pipe body 1 is a straight line.

[0038] When the axis of the pipe body 1 is a straight line, the condensed liquid (condensed water vapor and tiny oil droplets) can flow more smoothly towards the end of the pipe body 1 connected to the smoke exhaust passage 3, so that the condensed liquid can flow smoothly into the smoke exhaust passage 3, preventing the accumulation of water vapor and tiny oil droplets in the pipe body 1 and also preventing water vapor and tiny oil droplets from entering the oil fume monitoring component 2.

[0039] The cross-section of the inner wall of the pipe body 1 can be any suitable shape such as a rectangle, a triangle, an ellipse or a circle.

[0040] Preferably, the cross-section of the inner wall of the pipe body 1 is a circle.

[0041] When the cross-section of the inner wall of the pipe body 1 is a circle, the inner wall of the pipe body 1 is relatively smooth, and the condensed liquid (condensed water vapor and tiny oil droplets) can flow more smoothly towards the end of the pipe body 1 connected to the smoke exhaust passage 3, so that the condensed liquid can flow smoothly into the smoke exhaust passage 3, preventing the accumulation of water vapor and tiny oil droplets in the pipe body 1 and also preventing water vapor and tiny oil droplets from entering the oil fume monitoring component 2.

[0042] One end of the pipe body 1 is connected to the oil fume monitoring component 2. One end of the pipe body 1 can be directly inserted into the oil fume monitoring component 2 to connect one end of the pipe body 1 to the oil fume monitoring component 2.

The oil fume in the pipe body 1 enters the box body 21 through the air inlet 22. After the sensor in the box body 21 detects the oil fume concentration, the oil fume is discharged to the outside of the box body 21.

[0047] Further, a first sealing member 7 is provided between the mounting member 4 and the box body 21, and the first sealing member 7 surrounds the outside of the pipe body 1.

After the mounting member 4 and the box body 21 are fixed, the mounting member 4 and the box body 21 cooperate to squeeze the first sealing member 7, and the first sealing member 7 surrounds the outside of the pipe body 1, which can seal the gap between the air inlet 22 and the pipe body 1 to improve the sealing performance between the pipe body 1 and the box body 21.

[0049] The first sealing member 7 can be a gasket or an O-ring, or any other suitable form.

[0050] In this embodiment, the first sealing member 7 is sealing cotton, which can reduce the vibration of the oil fume monitoring component 2 while meeting the sealing performance.

[0052] Further, the mounting member 4 is detachably connected to the box body 21.

[0062] The second sealing member 8 can be a gasket or a sealing ring, or any other suitable form.

[0063] In this embodiment, the second sealing member 8 is a sealing cotton, which can reduce the vibration transmission between the smoke exhaust passage 3 and the pipe body 1 while meeting the sealing performance.
