An external thread is provided at the portion of the second rotating column 31 outside the mask shell 1, and the second rotating column 31 is fastened to the second auxiliary operation plate 49 by two nuts 51 close to each other, so that the second rotating column 31 can no longer move easily. A rotating rod 50 is fixedly connected to the outer wall of the second rotating column 31, so as to facilitate the rotation of the second rotating column 31.

[0039] The fourth bearing seat 33 is connected to the third spline sleeve 37 by limited rotation of the bearing, and the first spline shaft 11 is connected in the third spline sleeve 37 by limited sliding.

[0040] Embodiment 2:

[0041] like Figure 1 , 3, 5, and 6. The second bearing seat 16 is fixedly connected to the mask shell 1. The second bearing seat 16 is located at the top of the fifth bearing seat 40. The first spline sleeve 25 is rotatably connected to the second bearing seat 16 through the bearing limit. The first spline shaft 11 passes through the middle of the first spline sleeve 25, and the second spline shaft 36 is fixedly connected to the top of the third spline sleeve 37. The middle of the second spline shaft 36 is hollow, and the first spline shaft 11 passes through the middle of the second spline shaft 36.

The second rotating column 31 is rotated to disengage the third spline shaft 38 from the second spline sleeve 39, and the second spline shaft 36 moves into the first spline sleeve 25. The second spline shaft 36 can cooperate with the first spline sleeve 25, and the third spline shaft 38 cooperates with the second spline sleeve 39. At this time, the rotating first spline shaft 11 can only rotate the first fan 30. The air in the mask shell 1 keeps moving from top to bottom and goes out of the first filter element 5. The gas in the mask shell 1 is kept unobstructed and defogging is removed. The personnel can be in a healthy environment.

[0042] The bottom of the second bearing seat 16 and the fifth bearing seat 40 are fixedly connected to the fixed sleeve 26, and the fixed sleeve 26 is limitedly slidably connected to the electromagnet 28 through the slide groove thereon, and the first elastic member 27 is fixedly connected between the electromagnet 28 and the inner bottom of the fixed sleeve 26. The outer wall of the first spline sleeve 25 and the second spline sleeve 39 is fixedly connected to the annular iron block 29, and the electromagnet 28 and the annular iron block 29 are mutually attracted when energized.

[0043] Embodiment three:

[0044] like Figure 1 , 3 , 7. An L-shaped first auxiliary operation plate 48 is fixedly connected to the mask shell 1, and the first auxiliary operation plate 48 is rotatably connected to the fourth rotating column 47 through a bearing. The two ends of the fourth rotating column 47 are respectively fixedly connected to the second gear 41 and the second bevel gear 46. A rack 23 is fixedly connected to one side of the slide plate 21, and the rack 23 and the second gear 41 are meshed with each other. A sixth bearing seat 44 is fixedly connected to the mask shell 1, and the third rotating column 43 is rotatably connected to the sixth bearing seat 44. The two ends of the third rotating column 43 are respectively fixedly connected to the second fan 42 and the first bevel gear 45. The first bevel gear 45 and the second bevel gear 46 are meshed with each other.

[0045] Specific wearing implementation: At this time, the first filter element 5 is in a state of being installed, and the device is fixed on the head of the person through the fixing belt 2. Then, the inflation hole of the rubber pressing plate 7 is inflated through the external air hole, and a pressure sensor is provided in the cavity 18 to sense the gas pressure therein. The pressure sensor transmits a signal to the control display on the mask shell 1. When the pressure in the cavity 18 reaches a preset indication, the inflation is stopped, and then the one-way valve mechanism on the rubber pressing plate 7 prevents the gas in the cavity 18 from leaking. At this time, the cavity 18 fits the face of the person completely, so that there is no air leakage. At this time, the second rotating column 31 is rotated to rotate the first gear 32, and through the meshing action with the teeth 34, the second spline shaft 36 is inserted into the first spline shaft sleeve 25. At this time, the controller controls the start of the small motor 9 power supply to rotate the first spline shaft 11, and the first spline shaft 11 drives the third spline shaft sleeve 37 to rotate. The third spline shaft sleeve 37 drives the second spline shaft 36 to rotate. The second spline shaft 36 drives the first spline shaft sleeve 25 to rotate. The first spline shaft sleeve 25 drives the first fan 30 thereon to rotate, thereby transmitting the gas filtered from the second filter element 10 at the top from top to bottom to the inside of the mask shell 1. Then the gas can be breathed by the person, and then flow out from the first filter element 5 under the trend of air from top to bottom. Such a setting makes most of the turbid air exhaled by the human body discharged from the first filter element 5, avoiding the frequent replacement of the second filter element 10. Then the air with a certain guide will allow the person to breathe clean and healthy gas for a long time, and the fog in the device can be removed, making the person more comfortable to wear the device.

[0046] Specifically, the first filter element 5 is replaced. In an area where the device is not required to be worn, the controller controls the electromagnet 28 to be energized and the small motor 9 to be de-energized, so that the electromagnet 28 absorbs the annular iron block 29 to keep the first spline sleeve 25 and the first spline shaft 11 stationary. At this time, the second rotating column 31 is rotated to make the fourth bearing seat 33 and the third spline shaft 38 move downward, and the second spline shaft 36 is separated from the first spline sleeve 25. The third spline shaft 38 is inserted into the second spline sleeve 39, and the small motor 9 is started at this time, so that the second spline sleeve 39 rotates, thereby driving the threaded rod 13 to rotate. At this time, the slide plate 21 moves downward under the action of the thread and the limit, and the connecting plate 6 and the sliding column 24 move to one side under the limit of the parallelogram groove 22, so that the first filter element 5 moves out of the pipeline 3. This facilitates the replacement of the first filter element 5. And when the slide plate 21 moves downward, the rack 23 cooperates with the second gear 41 to rotate the second gear 41 and the second bevel gear 46. The second bevel gear 46 cooperates with the first bevel gear 45 to rotate the second fan 42. After the rubber plate 4 and the first filter element 5 are moved to the outside, the small motor 9 is reversed, and the second fan 42 blows the dust on the inner wall of the pipe 3. When the filter is removed, the inner wall of the pipe 3 is continuously backwashed to keep the pipe 3 in a clean and sanitary state, and the inner wall of the pipe 3 can be quickly dried by washing with water outside.

[0047] After the new first filter element 5 is installed, the small motor 9 is operated in a reversed state, so that the rubber plate 4 enters the pipe 3 and presses the annular plate 19, so that the external gas will not leak from the annular plate 19. Then, after the rubber plate 4 is installed, the small motor 9 is rotated forward, so that the second fan 42 inhales from the outlet, and the impurities that may remain after the installation are sucked out into the mask shell 1 and discharged. This facilitates subsequent healthy breathing. The coordination of one inhalation and one exhalation makes the device cleaner to use.

[0048] The technical scope of the present invention is not limited to the contents in the above description. Those skilled in the art can make various deformations and modifications to the above embodiments without departing from the technical idea of ​​the present invention, and these deformations and modifications should all fall within the protection scope of the present invention.
