Obviously, the described embodiments are some, but not all, of the embodiments of the present invention. All other embodiments obtained by those of ordinary skill in the art based on the described embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] Example 1: Please refer to Figures 1 to 8 : The present invention provides an environment-friendly smoke purification device for a barbecue grill, including: a purification device base 1; a fan 2 is installed inside the purification device base 1, a filter cotton cover plate 3 is installed on the left side of the top of the purification device base 1 by screws, an activated carbon filter cotton 4 is placed in the cavity below the filter cotton cover plate 3, and a group of air outlets 5 are provided on the left outer wall of the purification device base 1. The purification device base 1 is used to support the upper part structure of the device. When the fan 2 works, it will adsorb the smoke and dust generated during the use of the barbecue grill through the air guide seat 6, the lower air duct 7, the upper air duct 8 and the air inlet pipe 9. The activated carbon filter cotton 4 is used to filter the impurities in the smoke and dust. Finally, the filtered air will be discharged out through the air outlet 5. When it is necessary to replace the activated carbon filter cotton 4, just remove the screws on the filter cotton cover plate 3 first, and then pull up the filter cotton cover plate 3 to take out and replace the activated carbon filter cotton 4; a air guide seat 6 is fixed on the right side of the top of the purification device base 1, a lower air duct 7 is rotatably installed on the top of the air guide seat 6, an upper air duct 8 is slidably installed inside the top of the lower air duct 7, and an air inlet pipe 9 is fixed at the top end of the upper air duct 8. The air guide seat 6 is used to rotatably support the lower air duct 7, and the lower air duct 7, the upper air duct 8 and the air inlet pipe 9 are used to adsorb the smoke and dust generated during the use of the barbecue grill; a control panel 10 is installed on the left side of the lower air duct 7, and a positioning plug board 11 is slidably installed on the front and rear sides of the lower air duct 7. A positioning screw 12 is screwed on the right side of the upper air duct 8. During use, the fan 2 can be turned on through the control panel 10. When it is necessary to use this device to purify the smoke and dust generated during the use of the barbecue grill, first rotate the lower air duct 7 upward to the vertical state, and then push the positioning plug boards 11 on the front and rear sides of the lower air duct 7 downward to the bottom. At this time, the lower part of the positioning plug board 11 will be embedded in the vertical grooves on the front and rear sides of the air guide seat 6, so that the lower air duct 7 can be fixed in the vertical state. The positioning screw 12 is used to fix the height of the upper air duct 8 and the air inlet pipe 9.

[0020] In this embodiment, as Figure 2 , Figure 3 , Figure 6 and Figure 7As shown in the figure, a L-shaped plate is fixed to the right side of the upper air duct 8. There is a threaded hole corresponding to the positioning screw 12 below the L-shaped plate. A vertical convex plate is provided on the outer wall of the right side of the lower air duct 7, and eight threaded holes corresponding to the positioning screw 12 are equidistantly arranged on the vertical convex plate. During installation, the positioning screw 12 can be removed first. At this time, the upper air duct 8 can be pushed upward inside the top of the lower air duct 7, so that the height of the air inlet pipe 9 can be adjusted until the air inlet pipe 9 is adjusted to one side of the top of the barbecue grill, and the threaded hole below the L-shaped plate on the right side of the upper air duct 8 is aligned with one of the threaded holes on the vertical convex plate on the outer wall of the right side of the lower air duct 7. Then, the positioning screw 12 is screwed into these two threaded holes again, so that the height of the upper air duct 8 and the air inlet pipe 9 can be fixed.

[0021] In this embodiment, as Figures 1 - 5 shown, vertical grooves with the same width as the positioning insertion plate 11 are provided on both the front and rear sides of the air guide seat 6. And when the lower air duct 7 rotates to the vertical state and the positioning insertion plate 11 slides down to the bottom, the lower part of the positioning insertion plate 11 will be embedded in the vertical grooves on both the front and rear sides of the air guide seat 6. When it is necessary to use this device to purify the soot generated when using the barbecue grill, first rotate the lower air duct 7 upward to the vertical state, and then the positioning insertion plates 11 on both the front and rear sides of the lower air duct 7 can be pushed downward to the bottom. At this time, the lower part of the positioning insertion plate 11 will be embedded in the vertical grooves on both the front and rear sides of the air guide seat 6. Therefore, the lower air duct 7 can be fixed in the vertical state.

[0022] In this embodiment, as Figures 1 - 5 shown, the bottom left side of the lower air duct 7 is rotatably connected to the top left side of the air guide seat 6 through a rotating shaft. When the lower air duct 7 rotates to the vertical state, the cavity inside it will be connected to the cavity inside the air guide seat 6. The air guide seat 6 is connected to the suction port on the right side of the fan 2. When it is necessary to use this device to purify the soot generated when using the barbecue grill, first rotate the lower air duct 7 upward to the vertical state. At this time, the lower air duct 7 is connected to the air guide seat 6. Later, when the fan 2 is turned on, the soot generated when using the barbecue grill can be adsorbed through the air guide seat 6, the lower air duct 7, the upper air duct 8 and the air inlet pipe 9.

[0023] In this embodiment, as Figure 1 and Figure 8As shown, the air inlet pipe 9 is a hollow cylindrical pipe and is connected to the cavity inside the upper air guide pipe 8. There is a long strip-shaped opening that penetrates through the inside and outside at the lower left position of the air inlet pipe 9. Moreover, a vertical partition is provided in the cavity inside the air inlet pipe 9. When the fan 2 operates, it will adsorb the soot generated during the use of the barbecue grill through the air guide seat 6, the lower air guide pipe 7, the upper air guide pipe 8, and the air inlet pipe 9. During this process, the soot will first enter the cavity inside the air inlet pipe 9 through the long strip-shaped opening at the lower left of the air inlet pipe 9, and the vertical partition inside the air inlet pipe 9 can guide and disperse the air flow to ensure that the long strip-shaped opening at the lower left of the air inlet pipe 9 adsorbs the soot evenly.

[0024] In this embodiment, as Figures 1 - 5 shown, a U-shaped raised plate is provided on the outer side of the top of the air guide seat 6, and when the lower air guide pipe 7 rotates to the vertical state, the U-shaped raised plate on the outer side of the top of the air guide seat 6 will be in close contact with the outer wall of the lower air guide pipe 7. When it is necessary to use this device to purify the soot generated during the use of the barbecue grill, first rotate the lower air guide pipe 7 upward to the vertical state. At this time, the bottom of the lower air guide pipe 7 will be in close contact with the top of the air guide seat 6. At the same time, the U-shaped raised plate on the outer side of the top of the air guide seat 6 can also wrap the right outer wall and the front and rear outer walls of the lower air guide pipe 7, so that the lower air guide pipe 7 can be tightly connected to the air guide seat 6.

[0025] In this embodiment, as Figures 1 - 4 and Figure 7 shown, the upper air guide pipe 8 is an L-shaped pipe. The outer wall of the upper air guide pipe 8 is in close contact with the inner wall of the lower air guide pipe 7 and can slide up and down in the cavity inside the lower air guide pipe 7. After the lower air guide pipe 8 is adjusted up and down, the height of the air inlet pipe 9 can be adjusted, so that it can be used for barbecue grills of different heights, and the sealing performance of the contact surface between the upper air guide pipe 8 and the lower air guide pipe 7 can be ensured.

[0026] Embodiment 2, on the basis of Embodiment 1, as Figures 1 - 8 shown, a rectangular raised block is provided on the top of the filter cotton cover plate 3, and when the lower air guide pipe 7 rotates to the horizontal state, its outer wall will be in close contact with the outer wall of the rectangular raised block on the top of the filter cotton cover plate 3. A layer of rubber is also wrapped on the top outer wall of the air guide seat 6. When it is necessary to use this device to purify the soot generated during the use of the barbecue grill, first rotate the lower air guide pipe 7 upward to the vertical state. At this time, the bottom of the lower air guide pipe 7 will be in close contact with the top of the air guide seat 6. At this time, the rubber on the top outer wall of the air guide seat 6 can ensure the sealing performance, and the rectangular raised block on the top of the filter cotton cover plate 3 can not only facilitate pulling up the filter cotton cover plate 3, but also support the horizontally rotated lower air guide pipe 7.

[0027] Working principle of this embodiment: When it is necessary to use this device to purify the soot generated during the use of the barbecue grill, first rotate the lower air duct 7 upward to the vertical state. At this time, the bottom of the lower air duct 7 will be in close contact with the top of the air guide base 6. At the same time, the U-shaped convex plate on the outer side of the top of the air guide base 6 can also wrap the right outer wall and the front and rear outer walls of the lower air duct 7. Therefore, the lower air duct 7 can be tightly connected to the air guide base 6. Then, the positioning insertion plates 11 on the front and rear sides of the lower air duct 7 can be pushed downward to the bottom. At this time, the lower part of the positioning insertion plate 11 will be embedded in the vertical grooves on the front and rear sides of the air guide base 6. Therefore, the lower air duct 7 can be fixed in the vertical state. At this time, this device can be placed on the bottom of the barbecue grill through the purification device base 1, and the positioning screw 12 can be removed. Then, the upper air duct 8 can be pushed upward inside the top of the lower air duct 7, so that the height of the air inlet pipe 9 can be adjusted until the air inlet pipe 9 is adjusted to one side of the top of the barbecue grill, and the threaded hole under the L-shaped plate on the right side of the upper air duct 8 is aligned with one of the threaded holes on the vertical convex plate on the right outer wall of the lower air duct 7. Then, the positioning screw 12 is screwed into these two threaded holes again, so that the heights of the upper air duct 8 and the air inlet pipe 9 can be fixed. Then, connect this device to an external power supply, and turn on the fan 2 through the control panel 10. When the fan 2 works, it will adsorb the soot generated during the use of the barbecue grill through the air guide base 6, the lower air duct 7, the upper air duct 8 and the air inlet pipe 9. During this process, the soot will first enter the cavity inside the air inlet pipe 9 through the long strip-shaped opening under the left side of the air inlet pipe 9. And the vertical partition inside the air inlet pipe 9 can guide and disperse the air flow to ensure that the long strip-shaped opening under the left side of the air inlet pipe 9 adsorbs the soot evenly. Then, the soot will enter the cavity inside the purification device base 1 through the upper air duct 8, the lower air duct 7 and the air guide base 6. Finally, the air containing soot will be blown into the cavity where the activated carbon filter cotton 4 is located through the fan 2. At this time, the activated carbon filter cotton 4 can filter the impurities in the soot. Finally, the filtered air will be discharged outward through the air outlet 5, so as to realize the purification treatment of the soot. When this device needs to be put away after use, the positioning screw 12 can be removed and the upper air duct 8 can be pushed downward to the bottom. Then, the positioning insertion plate 11 can be pushed upward. At this time, the lower air duct 7 can be rotated leftward to the horizontal state. At this time, the lower air duct 7 and the upper air duct 8 will be folded and hidden on the top of the purification device base 1. At the same time, the air inlet pipe 9 will also be folded on the left side of the purification device base 1, which is convenient for storing this device. When it is necessary to replace the activated carbon filter cotton 4, just remove the screws on the filter cotton cover plate 3 first, and then pull up the filter cotton cover plate 3 to take out and replace the activated carbon filter cotton 4.

[0028] In this article, the following points need to be noted: 1. The attached drawings of this embodiment only involve the structures related to this embodiment. Other structures can refer to the general design.

[0029] 2. Under the condition of no conflict, the features in this embodiment and the embodiments can be combined with each other to obtain a new embodiment.
