The adapter 15 is fixedly connected to the support shell 11 by bolts, and then the motor 13 is fixed inside the support shell 11. At the same time, by pulling the adapter 15 and using multiple support frames 14, the motor 13 can be stably pulled out of the support shell 11, which is convenient for cleaning the airflow boost assembly 18.

[0039] like Figure 5 As shown, in one embodiment of the present application, the limiting member 12 includes a plate body 121 and a limiting groove 122 .

[0040] The plate body 121 is fixedly disposed on the inner wall of the supporting shell 11 .

[0041] The limiting groove 122 is formed on the plate body 121. The cross section of the limiting groove 122 is T-shaped.

[0042] In this embodiment, the cross section of the limiting groove 122 is made into a T-shape to help make the connection between the plate body 121 and the support frame 14 more stable.

[0043] like Figure 3 As shown, in one embodiment of the present application, the support frame 14 is configured to be T-shaped, and the support frame 14 includes a first connecting plate 141 and a second connecting plate 142 .

[0044] The first connecting plate 141 is slidably connected to the limiting groove 122 .

[0045] The second connecting plate 142 is disposed between the first connecting plate 141 and the motor 13. One end of the second connecting plate 142 is fixedly connected to the motor 13. The other end of the second connecting plate 142 is fixedly connected to the middle of the first connecting plate 141.

[0046] In this embodiment, the support frame 14 is set to be T-shaped to match the shape of the limiting groove 122 so that the support frame 14 can be inserted into the limiting groove 122 more snugly, thereby further improving the sliding stability of the support frame 14 in the limiting groove 122.

[0047] like Figure 2 As shown, in one embodiment of the present application, the adapter 15 is connected to the support shell 11 through a plurality of first connection bolts 19. The adapter 15 is connected to the first connection plate 141 through a plurality of second connection bolts 20.

[0048] In this embodiment, the plurality of first connecting plates 141 are connected to the adapter 15 via the second connecting bolts 20 , and the adapter 15 is connected to the support shell 11 via the plurality of first connecting bolts 19 , so that the first connecting plates 141 can be driven by the adapter 15 to slide relative to the limiting groove 122 .

[0049] like Figure 3 As shown, in one embodiment of the present application, the cleaning assembly 16 includes a plurality of cleaning brushes 161 and a plurality of connecting plates 162 .

[0050] The cleaning brush 161 is provided in plurality. One cleaning brush 161 is provided between two adjacent limiting members 12. One end of the cleaning brush 161 abuts against one limiting member 12. The other end of the cleaning brush 161 abuts against another limiting member 12.

[0051] The connecting plate 162 is provided in plurality. One connecting plate 162 is provided between two adjacent cleaning brushes 161. One end of the connecting plate 162 is fixedly connected to one cleaning brush 161. The other end of the connecting plate 162 is fixedly connected to another cleaning brush 161.

[0052] In this embodiment, multiple cleaning brushes 161 are connected into one by multiple connecting plates 162, and each cleaning brush 161 is partially in contact with the inner wall of the support shell 11. A cleaning brush 161 is arranged between two adjacent limiting members 12 to clean the inner wall of the support shell 11.

[0053] like Figure 3 As shown, in one embodiment of the present application, the cleaning brush 161 is configured to be in an arc shape that fits the inner wall of the supporting shell 11 .

[0054] like Figure 4As shown, in one embodiment of the present application, the self-locking assembly 17 includes a locking rod 171 and a return spring 172 .

[0055] The locking rod 171 is slidably disposed on the first connecting plate 141. One end of the locking rod 171 abuts against the inner wall of the limiting groove 122. The other end of the locking rod 171 is inserted into the connecting plate 162.

[0056] The return spring 172 is disposed in the first connecting plate 141. One end of the return spring 172 is fixedly connected to the locking rod 171. One end of the return spring 172 is fixedly connected to the first connecting plate 141.

[0057] In this embodiment, the locking rod 171 is slidably set on the first connecting plate 141, and one end of the locking rod 171 is against the inner wall of the limiting groove 122, and the other end of the locking rod 171 is inserted into the connecting plate 162, thereby driving the entire cleaning assembly 16 to move, and the reset spring 172 is used to help the locking rod 171 to reset, and help the locking rod 171 to separate from the connecting plate 162 when the locking rod 171 loses the restriction of the inner wall of the limiting groove 122.

[0058] like Figure 4 As shown, in one embodiment of the present application, a first inclined surface 171 a is provided at one end of the locking rod 171 close to the first connecting plate 141 .

[0059] In this embodiment, the first inclined surface 171a is used to help the locking rod 171 to be squeezed against the inner wall of the limiting groove 122 when entering the limiting groove 122, thereby helping the locking rod 171 to be inserted into the connecting plate 162, thereby locking the position of the connecting plate 162.

[0060] like Figure 4 As shown, in one embodiment of the present application, the locking rod 171 includes a locking shaft 171b and a limiting ring 171c.

[0061] The locking shaft 171b is slidably disposed on the first connecting plate 141. The locking shaft 171b is disposed through the first connecting plate 141. One end of the locking shaft 171b abuts against the inner wall of the limiting groove 122. The other end of the locking shaft 171b is inserted into the connecting plate 162.

[0062] The limiting ring 171c is slidably disposed in the first connecting plate 141. The limiting ring 171c is fixedly sleeved on the locking shaft 171b. The return spring 172 is fixedly connected to the limiting ring 171c.

[0063] In this embodiment, the locking shaft 171b is limited in its sliding position on the first connecting plate 141 by a limiting ring 171c fixedly mounted on the locking shaft 171b, and can also help the reset spring 172 to transmit force to the locking shaft 171b to achieve the reset function.

[0064] like Figure 3 As shown, in one embodiment of the present application, the airflow boosting assembly 18 includes a connecting plate 181 and a plurality of fan blades 182 .

[0065] The connecting plate 181 is fixedly sleeved on the power output shaft of the motor 13. The connecting plate 181 is configured in a circular ring shape.

[0066] The fan blades 182 are provided in a plurality. The fan blades 182 are fixedly connected to the outer circumferential surface of the connecting plate 181. The plurality of fan blades 182 are arranged at equal intervals along the circumferential direction of the connecting plate 181.

[0067] In this embodiment, the motor 13 drives the connecting plate 181 to rotate while driving the multiple fan blades 182 to rotate, thereby forming air flow on both sides of the fan blades 182, helping the gas to flow from one side of the support shell 11 to the other side of the support shell 11.

[0068] The technical features of the above-described embodiments may be arbitrarily combined, and the execution order of the method steps is not limited. To make the description concise, not all possible combinations of the technical features in the above-described embodiments are described.
