By setting the cleaning component 2, it is convenient to clean the impurities on the filter 14. The operation is simple and the filter 14 can be cleaned without removing it. At the same time, by setting the connection between the connecting plate 31 and the connecting block 3, it can be applied to any interface. When the connecting port is square, the connecting plate 31 and the second air outlet pipe 32 are directly removed, and then connected to the connecting pipe through the square block 12. When the connecting port is round, it can be directly connected through the second air outlet pipe 32, which improves adaptability.

[0027] Optionally, the cleaning assembly 2 includes: a connecting rod 21, the connecting rod 21 is fixed on the impeller 16, a cleaning plate 22 is fixedly installed on the side of the connecting rod 21 away from the impeller 16, and a plurality of evenly distributed brushes 23 are fixedly installed on the side of the cleaning plate 22 away from the connecting rod 21, and the brushes 23 are in contact with the filter screen 14. By setting the connecting rod 21, when the connecting rod 21 rotates with the impeller 16, the cleaning plate 22 and the brush 23 are driven to rotate to clean the impurities on the filter screen 14. The operation is simple and the filter screen 14 does not need to be disassembled for cleaning.

[0028] Optionally, two groups of symmetrically distributed first circular grooves 4 are provided on the top of the connecting plate 31, and a second circular groove 40 corresponding to the first circular groove 4 is provided on the top of the two connecting blocks 3. A fixed disk 41 is fixedly installed inside each first circular groove 4, and a spring 42 is fixedly installed on the top of the fixed disk 41. A top disk 43 is fixedly installed on the top of the spring 42. The middle part of the top disk 43 and the fixed disk 41 is rotated through the same guide rod 44, and two symmetrically distributed limiting rods 45 are fixedly installed on the bottom of the guide rod 44. The middle part of the connecting plate 31 is located on both sides of the first circular groove 4 and the middle part of the connecting plate 31 is located on both sides of the second circular groove 40. Limiting grooves 46 corresponding to the limiting rods 45 are provided, and a handle 47 is fixedly installed on the top of each guide rod 44. A circular groove 5 corresponding to the second circular groove 40 is provided inside the connecting block 3;

[0029] By setting a handle 47, when the handle 47 is turned, the top plate 43 is pressed downward at the same time, and the spring 42 contracts, so that the top plate 43 fits into the upper surface of the inner wall of the placement groove 7, and then the handle 47 is rotated to disengage the limit rod 45 from the limit groove 46, and then the handle 47 is released. Under the action of the spring 42, the limit rod 45, the guide rod 44, and the top plate 43 are driven to move upward, so that the limit rod 45 fits into the circular groove 5, thereby fixing the connecting plate 31 and the connecting block 3 together. The operation is simple, and it is convenient to remove and unload the second air outlet pipe 32 and the connecting plate 31 from the connecting block 3 and the square block 12.

[0030] Optionally, a discharge port 24 is opened at the bottom end of the suction pipe 13, and a dust box 25 is fixedly installed at the bottom end of the suction pipe 13 at the position of the discharge port 24. By setting the dust box 25, the impurities cleaned on the filter 14 are collected, thereby facilitating the processing of the cleaned impurities.

[0031] Optionally, the height of the first circular groove 4 is shorter than that of the second circular groove 40 , which makes it easier to fix the connecting plate 31 and the connecting block 3 .

[0032] Combine Figure 5-6 As shown, the embodiment of the present disclosure provides a boiler induced high-efficiency energy-saving fan, the diameter of the circular groove 5 is larger than the diameter of the first circular groove 4 and the second circular groove 40, which facilitates the rotation of the guide rod 44 and the limit rod 45 to fix the connecting plate 31 and the connecting block 3 together.

[0033] Combine Figure 6 As shown, the embodiment of the present disclosure provides a boiler-induced high-efficiency energy-saving fan, and two symmetrically distributed semicircular grooves 6 are provided inside each connecting block 3 above the circular groove 5. The semicircular grooves 6 and the limiting grooves 46 are in a cross shape. By providing the semicircular grooves 6, it is easier to fix the limiting rod 45, so that the connecting plate 31 and the connecting block 3 are fixed together more stably.

[0034] Combine Figure 4 As shown, the embodiment of the present disclosure provides a boiler-induced high-efficiency energy-saving fan, and two groups of symmetrically distributed placement grooves 7 are provided at the top of the connecting plate 31. The diameter of the placement grooves 7 is larger than the first circular groove 4 and the second circular groove 40. By providing the placement grooves 7, it is more convenient to place the top plate 43 and the handle 47.

[0035] Combine Figure 5 As shown, the embodiment of the present disclosure provides a boiler-induced high-efficiency energy-saving fan, wherein a first baffle 8 is fixedly installed on one side of the interior of each circular groove 5, and the first baffle 8 corresponds to the edge of one of the semicircular grooves 6, and a second baffle 81 is fixedly installed on the edge of one of the limit grooves 46 inside the circular groove 5. By setting the first baffle 8 and the second baffle 81, when the handle 47 is rotated, the limit rod 45 and the guide rod 44 are driven to rotate. When the limit rod 45 is in contact with the first baffle 8, it means that the semicircular groove 6 corresponds to the limit rod 45. Then, the handle 47 is released, and the limit rod 45 is clamped into the corresponding semicircular groove 6 under the action of the spring 42. When the limit rod 45 is in contact with the second baffle 81, it means that the limit rod 45 corresponds to the limit groove 46. The guide rod 44 and the limit rod 45 can be taken out of the second circular groove 40 in the connecting block 3, so that the connecting plate 31 and the connecting block 3 are not fixed together, thereby making the first air outlet pipe 11 and the second air outlet pipe 32 not connected together.

[0036] Combine Figure 4 As shown, the embodiment of the present disclosure provides a boiler-induced high-efficiency energy-saving fan, and each handle 47 is made of plastic, which makes it easier to rotate the handle 47 and increases the friction between the hand and the handle 47.
