The activated carbon filter 5 can be easily replaced through the annular slide groove 17. The suction hood 6 is rotatably installed on the top of the mounting seat 3. An annular guide groove 18 is provided on the top of the mounting seat 3. An annular guide block 19 is slidably installed in the annular guide groove 18. The bottom of the suction hood 6 is fixedly connected to the annular guide block 19. Through the joint action of the annular guide groove 18 and the annular guide block 19, the rotation of the suction hood 6 can be guided and supported. A suction pipe 7 is fixedly installed on the top of the suction hood 6, a suction component that generates suction is provided in the mounting box 2, and a driving component for controlling the rotation of the suction hood 6 is provided on the mounting seat 3.

[0028] In this embodiment, the above-mentioned driving assembly includes a first gear 13, a support shaft 14, a second gear 15 and an inner gear ring 16. The top end of the rotating shaft 9 extends into the suction hood 6. The first gear 13 is fixedly sleeved on the top end of the rotating shaft 9. The support shaft 14 is rotatably mounted on the top of the mounting base 3 and is located on the right side of the rotating shaft 9. The second gear 15 is fixedly sleeved on the support shaft 14 and meshes with the first gear 13. The inner gear ring 16 is fixedly mounted on the inner wall of the suction hood 6 and meshes with the second gear 15. It should be noted that the number of teeth and the radius of the first gear 13 are much smaller than the number of teeth and the radius of the second gear 15. The difference in the number of teeth between the first gear 13 and the second gear 15 can make the rotation speed of the suction hood 6 much smaller than the rotating shaft 9.

[0029] In this embodiment, the above-mentioned suction assembly includes a motor 8, a rotating shaft 9, fan blades 10, an air inlet pipe 11 and an air outlet pipe 12. The motor 8 is fixedly mounted on the bottom inner wall of the installation box 2, the rotating shaft 9 is fixedly mounted on the output shaft end of the motor 8, the fan blades 10 are fixedly sleeved on the rotating shaft 9, the air inlet pipe 11 is fixedly mounted on the top of the installation box 2, the top of the air inlet pipe 11 extends into the suction hood 6, the air outlet pipe 12 is fixedly mounted on the bottom of the installation box 2, the bottom end of the air outlet pipe 12 extends below the liquid level in the filter box 1, and a one-way valve 20 located in the filter box 1 is fixedly mounted on the air outlet pipe 12. The one-way valve 20 can be used to avoid sucking clean water into the filter box 1. A porous copper sheet 21 is fixedly mounted on the bottom end of the air outlet pipe 12. A large amount of bubbles can be generated through the porous copper sheet 21, thereby increasing the contact area between air and clean water and improving the filtering effect.

[0030] In this example, a control switch is fixedly installed on the filter box 1, and the control switch and the motor 8 are electrically connected to the battery 25 through a wire, and the start and stop of the motor 8 can be controlled by the control switch.

[0031] Through the above structure, the porous smoke absorption hood provided by the utility model can utilize the rotation of the fan blades 10 to generate suction, thereby sucking air and smoke, and utilize the activated carbon filter 5 and clean water to filter the air and smoke, so that smokers can smoke safely near the device, and can also control the suction hood 6 and the suction tube 7 to rotate 360 ​​degrees, thereby sucking the air and smoke in the area near the device, reducing the dead angle of smoking smoke, and improving the ability to suck smoke. In specific use, when the smoker wants to smoke, he comes to the device and controls the motor 8 to run. The motor 8 drives the rotating shaft 9 and the fan blades 10 to rotate, and utilizes the rotation of the fan blades 10 to generate suction force to extract the outside air. At the same time, driven by the rotating shaft 9, the first gear 13 starts to rotate. By utilizing the first gear The meshing rotation of the wheel 13 and the second gear 15 can drive the second gear 15 to start rotating, and through the difference in the number of teeth between the first gear 13 and the second gear 15, the second gear 15 is controlled to rotate at a speed much smaller than that of the first gear. The meshing rotation of the second gear 15 and the inner ring 16 drives the suction hood 6 and the suction pipe 7 to rotate, and then can rotate 360 ​​degrees to suck the surrounding air. The smoke undergoes a filtering and adsorption when passing through the activated carbon filter 5. The sucked air enters the clean water in the filter box 1 through the air outlet pipe 12. A large amount of bubbles are generated when the airflow passes through the porous copper sheet 21, which increases the contact area between the air and the clean water and improves the filtering effect of the smoke in the air. At this time, smokers next to the device can smoke without worrying about the harm of secondhand smoke to others.

[0032] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can easily think of changes or substitutions within the technical scope recorded in the utility model, which should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope of the claims.
