[0002] Ambient air refers to the composition and mass distribution of gases in the atmosphere, as well as the concentration of particulate matter and pollutants in it. It is the air we breathe and has a significant impact on our health and quality of life. Ambient air pollution refers to the presence of pollutants in the atmosphere that exceed a certain limit, posing a threat to the environment and human health. Waste gas refers to gas emissions generated from various industries and production processes. Most factories, vehicles and energy production processes produce waste gas. Waste gas may contain various harmful substances, such as sulfur dioxide, nitrogen oxides, volatile organic compounds, etc. These waste gases are discharged into the air, which will have adverse effects on the environment and human health.

DETAILED DESCRIPTION

[0024] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0025] In the description of the present invention, it should be understood that the terms "upper", "lower", "front", "back", "left", "right", "top", "bottom", "inside", "outside", etc., indicating directions or positional relationships, are based on the directions or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific direction, be constructed and operated in a specific direction, and therefore should not be understood as a limitation on the present invention.

[0026] Reference Figure 1-Figure 6, an absorption device for sampling ambient air and exhaust gas, comprising a sleeve 1 and a connecting pipe 2 arranged at the top of the sleeve 1, a filter screen 3 is arranged inside the connecting pipe 2, a motor 4 is arranged outside the connecting pipe 2, and further comprising: a rotating rod 5, fixedly connected to the output end of the motor 4; a convex block 6, which passes through the rotating rod 5 and is fixedly connected to the rotating rod 5; a fixed plate 7, fixedly connected to the inner wall of the connecting pipe 2; a sliding rod 8, which is slidably connected to the fixed plate 7; an inclined block 9, fixedly connected to the bottom of the sliding rod 8; a vibrating rod 10, fixedly connected to the top of the sliding rod 8; a first return spring 11, sleeve It is arranged on the sliding rod 8. When it is necessary to process the particulate matter on the filter screen 3, the rotating rod 5 is driven to rotate by starting the motor 4. The rotating rod 5 drives the protrusion 6 to rotate and abut against the inclined surface of the inclined surface block 9. Under the guidance of the fixed plate 7, the inclined surface block 9 can slide upward, compressing the first return spring 11 to drive the vibration rod 10 to abut against the bottom of the filter screen 3. This reciprocating abutment can make the filter screen 3 vibrate continuously, so that the particulate matter on the filter screen 3 vibrates and falls off, thereby achieving the effect of cleaning the filter screen 3 and preventing the filter screen 3 from being blocked, so as to make the air and exhaust gas collection efficiency higher and the air intake smoother.

[0027] One end of the rotating rod 5 close to the motor 4 passes through the connecting tube 2 and is rotatably connected to the connecting tube 2. The connecting tube 2 supports the rotating rod 5, so that the protrusion 6 can be more stable when rotating.

[0028] A mounting plate 12 is fixedly connected to the outer wall of the connecting pipe 2 on one side close to the motor 4 , and the motor 4 is placed on the mounting plate 12 . The mounting plate 12 supports the motor 4 so that the motor 4 can run stably.

[0029] Two sliding holes are provided on the surface of the fixed plate 7, and the sliding rod 8 passes through the sliding holes of the fixed plate 7 and is slidably connected with the sliding holes of the fixed plate 7. When the inclined block 9 is resisted, the sliding rod 8 can slide up, and the sliding holes of the fixed plate 7 can guide and support the sliding rod 8 to facilitate stable vertical movement of the sliding rod 8.

[0030] A semicircular block 13 is fixedly connected to the top of the sliding rod 8. The sliding rod 8 drives the vibration rod 10 and the semicircular block 13 to beat the filter screen 3, so that the filter screen 3 can be hit more forcefully and the vibration effect of the filter screen 3 can be stronger.

[0031] One end of the first return spring 11 is fixedly connected to the ramp block 9, and the other end of the first return spring 11 is fixedly connected to the fixed plate 7. When the ramp block 9 slides up, the first return spring 11 is compressed. When the protrusion 6 is separated from the ramp block 9, the first return spring 11 can automatically return the ramp block 9.

[0032] Long strip grooves are provided on the inner walls on both sides of the connecting pipe 2, and a second return spring 14 is fixedly connected to the inner wall at the top of the long strip groove of the connecting pipe 2, and a slide plate 15 is fixedly connected to the bottom of the second return spring 14, and the slide plate 15 is fixedly connected to the filter screen 3. When the filter screen 3 is tapped, it will slide upward, and the filter screen 3 will slide upward on the inner wall of the long strip groove of the connecting pipe 2 by compressing the second return spring 14 through the slide plate 15. Then when the semicircular block 13 is separated from the filter screen 3, the second return spring 14 can drive the filter screen 3 to automatically reset through the slide plate 15. This reciprocating sliding can make the filter screen 3 vibrate more strongly, and more effectively make the particles on the surface of the filter screen 3 vibrate and fall off, so that the air and exhaust gas can enter the sleeve 1 more smoothly for collection.

[0033] There are two groups of inclined plane blocks 9 and sliding rods 8, and the two groups of inclined plane blocks 9 and sliding rods 8 are symmetrically arranged with the center line of the fixed plate 7 as the symmetry axis. Through the two groups of inclined plane blocks 9, the protrusion 6 can repeatedly contact the inclined plane blocks 9, and the two groups of sliding rods 8 can respectively beat the two sides of the filter screen 3, so that the vibration effect is better.

[0034] In the utility model, when collecting gas, the gas enters through the connecting pipe 2, passes through the filter screen 3 and enters the sleeve 1, and the filter screen 3 filters the particles in the gas. When the filter screen 3 is used for a long time and the particles block the filter screen 3, the sleeve 1 is inverted, and then the motor 4 is started to drive the rotating rod 5 to rotate, and the rotating rod 5 drives the protrusion 6 to rotate. The protrusion 6 contacts the inclined surface of the inclined surface block 9 to make the inclined surface block 9 slide up, driving the sliding rod 8 to slide in the sliding hole of the fixed plate 7, and at the same time compressing the first reset spring 11, driving the semicircular block 13 to the filter screen 3 through the vibration rod 10. The bottom is slapped. When the filter screen 3 is slapped, the second return spring 14 is compressed upward by the slide plate 15 and slides in the strip-shaped long groove of the connecting pipe 2. When the protrusion 6 is separated from the inclined block 9, the first return spring 11 drives the sliding rod 8 and the inclined block 9 to reset, and the second return spring 14 drives the filter screen 3 to reset. This reciprocating motion can make the filter screen 3 vibrate continuously, so that the particles on the filter screen 3 vibrate and fall to the ground, which can prevent the filter screen 3 from being blocked and affecting the collection efficiency, and help to make the air and exhaust gas enter the sleeve 1 more smoothly during collection.

[0035] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
