Referring to fig. 1 to 7, an embodiment of the present application provides an oil mist flow path structure of an oil mist collecting device, which includes a first oil stain removing device 2, a first steam guiding pipe 22, and a backflow preventing opening plate 3. The both ends of casing 1 are equipped with air inlet 11 and gas outlet 12 respectively, and casing 1 inside is equipped with preceding filter 13, retroverted centrifuge 14 and back filter vat 15 in proper order from air inlet 11 to gas outlet 12 direction, still includes: the first oil stain removing device 2 is arranged on the shell 1, and the first oil stain removing device 2 is positioned between the air inlet 11 and the front filter 13; the first oil stain removing device 2 comprises a shell 21, and two sides of the shell 21 are respectively communicated with the air inlet 11 and the air outlet 12; the shell 21 is provided with a first steam guide pipe 22, a steam outlet of the first steam guide pipe 22 faces the front filter 13, and a steam inlet of the first steam guide pipe 22 is provided with an air inlet valve 23; a through hole is formed in one side, communicated with the air inlet 11, of the shell 21, a backflow prevention opening plate 3 is arranged in the through hole, the backflow prevention opening plate 3 comprises a first blade 31 and a second blade 32, the first blade 31 is fixed on the upper half part of the through hole, and the second blade 32 is rotationally connected with the first blade 31 through a rotating shaft 4; the rotating shaft 4 is connected with a driving device for driving the rotating shaft 4 to rotate.

Working principle and effect: when the oil mist collecting device works, the shell 21 of the first oil stain removing device 2 is communicated with the air inlet 11, namely the second blades 32 and the first blades 31 are overlapped and are positioned on the upper half part of the through hole, and gas flows from the air inlet 11 to multiple filtration through the lower half part of the through hole and is discharged from the air outlet 12; after long-time use, oil stains can remain on the inner wall of the channel and the filtering device, so that the inner wall and the oil stains on the filtering device need to be cleaned regularly, firstly, the oil mist collecting device is ensured to be in a stop working state, the driving device is used for controlling the rotation shaft 4 to rotate so as to drive the second blade 32 to rotate, and when the second blade 32 rotates to the lower half part of the through hole and forms a complete closed circular plate with the first blade 31 (as shown in fig. 5 to 6), the rotation is stopped, and at the moment, the through hole is blocked to prevent steam from flowing back from the through hole; then, connect the outer end of steam honeycomb duct high pressure steam equipment, open the air inlet valve 23 on the steam honeycomb duct, steam enters into the oil mist collection device from the steam honeycomb duct in, because the steam outlet of steam honeycomb duct is towards the direction that preceding filter 13 is located, the through-hole of opposite direction is stopped up, consequently, steam can flow through the back inclined centrifuge 14 from preceding filter 13 and flow back filter vat 15 again, dissolve its surface attached oil stain granule, and evaporate the material gasification after dissolving, realize abluent effect, thereby reach and need not dismantle also can carry out abluent purpose to inner structure, labour saving and time saving.

Further, steam cleaning, also known as supersaturated steam cleaning, is one method of cleaning. The oil stain particles on the surface to be cleaned are dissolved by saturated steam under the action of high temperature and high pressure, and are vaporized and evaporated, so that the surface cleaned by the saturated steam can reach an ultra-clean state. At the same time, the supersaturated steam can effectively cut into any tiny holes and cracks, and strip and remove stains and residues in the holes and cracks.

Further, the steam device may be a high pressure steam cleaner, such as Paiytt electric heating series high pressure hot water and high pressure steam cleaner, model 6M2504H, 6M108S. The high pressure steam cleaner is one kind of cleaning machine with saturated steam and with high temperature and high pressure to clean and gasify oil trace waste on the surface of part. And the cleaning agent can clean all fine gaps and holes, separate and remove oil marks and residues, save water, clean, dry and have low cost, and replace expensive liquid nitrogen cleaning. The steam cleaning has the advantages of saving water, reducing the application of various cleaning solutions, protecting environment and ensuring safety.

Principle of high pressure steam cleaner: the instant vaporization technology is always a key technology of a high-pressure steam cleaner, namely the high-pressure high-temperature steam according to the output rate accelerates the body-building movement rate of the molecular structure in the dirt to split the internal structure of the dirt so as to achieve the aim of cleaning various dirt which is difficult to remove.

Further, the temperature of the steam cannot be too high or too low, the too high temperature affects the equipment, and the too low temperature cannot achieve the effect of removing the oil stain, so that the constant steam temperature needs to be maintained in the whole oil stain removing process.

Because the steam can gradually decrease from the front end to the rear end in the process, the cleaning effect can not be realized when the temperature is too low, and therefore, the second oil stain removing device 6 is also arranged at the rear end, namely the rear filter vat 15, and the steam outlet of the second steam guide pipe 61 faces the rear filter vat 15 opposite to the first steam guide pipe 22, so that the steam is directly conveyed from the rear to the front, and the rear filter vat 15 at the tail end of the steam flowing through the first steam guide pipe 22 can be effectively cleaned.

Further, as shown in fig. 2, the steam flowing out of the second steam guide pipe 61 can clean the filter screen and the outer wall of the rear filter tub 15, so as to realize cleaning in a large area.

In one embodiment, as shown in fig. 3, the driving device includes a rotating wheel 51 and a connecting rod 52, one end of the connecting rod 52 is provided with a driving motor 53, and the other end is connected with the rotating wheel 51. The connecting rod 52 is rotated by the driving motor 53, and the connecting rod 52 rotates the rotating wheel 51. The driving motor 53 can be a relatively common dc miniature motor, and has the characteristics of small volume, low noise, long service life, and the like, and is widely applied to the fields of electric toys, electric tools, medical appliances, and the like, and the model is as follows: RF-300CA-11400, RF-500TB-12560, RF-370CA-15370, RE-M14-A, and the like; the AC miniature motor can also be used for occasions suitable for light load and high-speed operation, such as an electric fan, an air purifier, a dust collector and the like, and the model is as follows: M10-FF-77D4512-XX, M10-FF-85P4212-XX, M10-FF-106D4512-XX, M10-FF-126D4165-XX, etc.

Further, the rotation shaft 4 is connected to the rotation wheel 51. The rotating wheel 51 drives the rotating shaft 4 to rotate, so that the small-range rotation is realized, the structure is simple, and the inner space of the shell 21 is not occupied.

In one embodiment, as shown in fig. 1 to 3, a control switch 24 is provided at the top of the cabinet 1 for controlling the driving motor 53. The control switch 24 is arranged at the top of the shell 1, namely outside the oil mist collecting device, so that manual operation is facilitated; the control switch 24 is electrically connected with the driving motor 53, and the control switch 24 controls the start and stop of the driving motor 53, so as to control the rotating shaft of the rotating shaft 4.
