The fan body 6 can be selected to be inserted into the fan mounting port, and the fan body 6 and the fan inner shell 2 can be connected by bolts, and of course the fan body 6 and the fan inner shell 2 can also be connected by riveting. After the fan body 6 is installed in the fan mounting port, the blowing direction of the fan body 6 is towards the inside of the fan inner shell 2, and the first end of the fan shell 1 can be connected with the first end of the fan inner shell 2 by welding to achieve a sealing effect.

[0041] The side wall of the fan inner shell 2 described above can be selected to be provided with a plurality of circular ventilation ports 21, and of course a plurality of rectangular ventilation ports 21 can also be selected, the plurality of ventilation ports 21 are distributed along the circumference of the cylindrical fan inner shell 2, or a rectangular ventilation port 21 can also be selected to be arranged on the side wall of the fan inner shell 2. The end face of the second end of the fan shell 1 can be selected to be parallel to the end face of the second end of the fan inner shell 2, and a circular through hole can be selected to be arranged on the end face of the second end of the fan shell 1 as the air outlet 13, and of course a rectangular air outlet 13 can also be selected to be arranged on the end face of the second end of the fan shell 1.

[0042] It can be understood that in other embodiments, the fan shell 1 and the fan inner shell 2 can be selected as a rectangular shell, the four sides of the fan inner shell 2 correspond to the four sides of the fan shell 1 one by one and are parallel to each other, and the first end and the second end of the fan shell 1 and the fan inner shell 2 are two ends of the rectangular shell in the length direction. A rectangular through hole can be selected to be provided on the end face of the first end of the fan inner shell 2 as a fan mounting port, the fan body 6 is inserted into the fan mounting port, and the fan body 6 and the fan inner shell 2 are connected by bolts. A circular air vent 21 can be selected to be provided on each side of the rectangular shell of the fan inner shell 2, of course, a plurality of rectangular air vents 21 can also be selected to be provided on each side of the rectangular shell of the fan inner shell 2 respectively, or a rectangular air vent 21 can also be selected to be provided on one side of the rectangular shell of the fan inner shell 2.

[0043] In specific use, the fan body 6 starts to blow air into the inside of the fan inner shell 2 at the first end of the fan inner shell 2, the gas flows towards the inside of the fan inner shell 2, turns at the second end of the fan inner shell 2, enters the first gap from the air vent 21 on the side wall of the fan inner shell 2, and moves towards the second end of the fan shell 1 in the first gap. After the gas enters the second gap, it is discharged from the fan shell 1 through the air outlet 13.

[0044] By providing the fan shell 1, the fan inner shell 2 and the fan body 6; providing the fan mounting port at the first end of the fan inner shell 2, closing the second end of the fan inner shell 2, and arranging the fan body 6 at the fan mounting port; arranging the fan inner shell 2 in the inside of the fan shell 1, connecting the first end of the fan inner shell 2 with the first end of the fan shell 1, and closing the first end of the fan shell 1; providing the air vent 21 on the side wall of the fan inner shell 2, having the first gap between the side wall of the fan inner shell 2 and the side wall of the fan shell 1, connecting the first gap with the air vent 21, having the second gap between the second end of the fan inner shell 2 and the second end of the fan shell 1, connecting the second gap with the first gap, and arranging the second end of the fan shell 1 opposite to the second end of the fan inner shell 2, and providing the air outlet 13 on the end face of the second end of the fan shell 1, and connecting the air outlet 13 with the second gap, finally making the gas blown by the fan body 6 into the fan inner shell 2 enter the first gap through the air vent 21, and the gas moves from the first gap to the second gap and is discharged from the fan shell 1 through the air outlet 13, which prolongs the moving distance of the gas in the inside of the cleaner fan, slows down the flow rate of the gas when it is discharged from the air outlet 13, and reduces the noise when the cleaner fan is used. The fan body 6 is arranged in the fan inner shell 2, and one end of the fan inner shell 2 and the fan shell 1 is sealingly connected, which improves the air tightness between the fan inner shell 2 and the fan shell 1, and makes the fan inner shell 2 and the fan shell 1 become an integral structure, and improves the position stability of the fan inner shell 2 relative to the fan shell 1.

[0045] Referring to Figures 1 to 8 As shown in some embodiments, the number of air vents 21 is multiple, and the multiple air vents 21 are arranged on the side wall of the fan inner shell 2 to form a grid structure. Specifically, the shape of the air vent 21 can be selected as a rectangle. When the fan inner shell 2 is a cylindrical shell, the length direction of the air vent 21 is the same as the length direction of the fan inner shell 2. The multiple air vents 21 are arranged on the side wall of the fan inner shell 2 along the circumferential direction of the fan inner shell 2. The distance between every two adjacent air vents 21 is equal.

[0046] Of course, in other embodiments, when the fan inner shell 2 is a rectangular shell, the air vent 21 can be selected as a circular through hole. The multiple air vents 21 are uniformly distributed on each side of the fan inner shell 2. The distance between every two adjacent air vents is equal.

[0047] By setting the number of air vents 21 to be multiple, the multiple air vents 21 are arranged on the side wall of the fan inner shell 2 to form a grid structure. The gas can enter the first gap through the air vent 21 from each position of the side wall of the fan inner shell 2. This avoids the influence of the increase of the air pressure in the fan inner shell 2 on the normal work of the fan body 6. The grid structure can ensure the strength of the fan inner shell 2, thereby improving the stability of the fan shell 1 during use.

[0048] Referring to Figures 1 to 8 As shown in some embodiments, the fan shell 1 includes a fan shell body 11 and a fan shell cover 12. One end of the fan shell body 11 is connected with the first end of the fan inner shell 2. The other end of the fan shell body 11 is provided with the fan shell cover 12. The fan shell cover 12 is detachably connected with the fan shell body 11. Specifically, the fan shell body 11 can be selected as a cylindrical structure. The fan inner shell 2 is located in the inside of the cylinder. One end of the cylinder is connected with the first end of the fan inner shell 2. The other end of the cylinder is connected with the fan shell cover 12. The side wall of the cylinder is the side wall of the fan shell 1. Of course, the fan shell body 11 can also be selected as a rectangular cylinder. The fan inner shell 2 is located in the inside of the rectangular cylinder. One end of the rectangular cylinder is connected with the first end of the fan inner shell 2. The other end of the rectangular cylinder is connected with the fan shell cover 12. The four side surfaces of the rectangular cylinder are the side walls of the fan shell 1.

[0049] The above-mentioned fan shell cover 12 can be provided with a buckle. A clamping groove is arranged on the fan shell body 11. When the fan shell cover 12 is covered on the fan shell body 11, the buckle is clamped in the clamping groove to achieve the detachable connection between the fan shell cover 12 and the fan shell body 11. Of course, the fan shell body 11 and the fan shell cover 12 can also be connected by bolts.

[0050] By setting the fan shell body 11 and the fan shell cover 12 as the fan shell 1, one end of the fan shell body 11 is connected with the first end of the fan inner shell 2, the other end of the fan shell body 11 is provided with the fan shell cover 12, and the fan shell cover 12 is detachably connected with the fan shell body 11, so that the space between the fan shell 1 and the fan inner shell 2 can be cleaned and maintained after the fan shell cover 12 is detached, thereby avoiding dust accumulation between the fan shell 1 and the fan inner shell 2 to affect the normal use of the cleaner fan.

[0051] Referring to Figures 1 to 8 and Figure 12 In some embodiments, the fan body 6 is further provided with a filter 61 adapted to filter the gas entering the fan inner shell 2. Specifically, the filter 61 can be arranged on the outer side of the fan body 6. The filter 61 can be a cloth filter screen or a metal grid, as long as it can prevent foreign matter from entering the interior of the fan inner shell 2 through the fan body 6.

[0052] By arranging the filter 61 on the fan body 6, the gas entering the fan inner shell 2 can be filtered, thereby preventing foreign matter from entering the interior of the fan inner shell 2 through the fan body 6 and blocking the air vents 21, and ensuring the stability of the cleaner fan during continuous operation.

[0053] Referring to Figures 1 to 12 In some embodiments, the gas outlet 13 is located at the center of the fan shell cover 12. Specifically, when the fan inner shell 2 and the fan shell 1 are both cylindrical columns, the fan shell cover 12 is circular, and the circular gas outlet 13 is arranged at the center of the fan shell cover 12, and the axis of the gas outlet 13 coincides with the axis of the fan shell 1. Of course, when the fan shell 1 and the fan inner shell 2 are rectangular shells, the fan shell cover 12 is rectangular, and the circular gas outlet 13 is arranged at the center of the fan shell cover 12.

[0054] By arranging the gas outlet 13 at the center of the fan shell cover 12, the gas moving from the first gap to the second gap and finally discharged from the fan shell 1 through the gas outlet 13 has a similar moving distance in the first gap and the second gap, thereby avoiding that one air vent 21 is close to the gas outlet 13, so that the gas can quickly enter the gas outlet 13 from the air vent 21, thereby affecting the slowing effect of the fan shell 1 and the fan inner shell 2 on the gas flow rate.

[0055] Referring to Figures 9 to 12As shown, the second aspect of the present disclosure discloses a dust collector base station, which comprises the dust collector fan described above, and further comprises a dust box 3, a dust suction pipe 4 and a return air pipe 5. One end of the dust collector fan is in communication with the dust box 3, and the other end is in communication with the return air pipe 5. The dust suction pipe 4 is arranged on the dust box 3 and in communication with the dust box 3.

[0056] Specifically, the end of the dust collector fan away from the air outlet 13 can be connected with the dust box 3, and a sealing strip can be arranged at the connection between the dust box 3 and the dust collector fan. The air outlet 13 of the dust collector fan can be in communication with the return air pipe 5 by screw connection. Alternatively, one end of the return air pipe 5 can be inserted into the air outlet 13, and then the return air pipe 5 and the air outlet 13 can be connected by using sealing glue. The dust suction pipe 4 can be inserted into a connecting hole arranged on the side of the dust box 3, and the dust suction pipe 4 and the dust box 3 can be connected by using sealing glue. Alternatively, a nylon buckle can be arranged in the connecting hole, and the end of the dust suction pipe 4 can be inserted into the connecting hole and clamped with the nylon buckle, so as to realize the connection between the dust suction pipe 4 and the dust box 3.

[0057] The dust collector base station described above is used to connect a sweeping machine. The dust suction pipe 4 is used to suck the garbage stored in the sweeping machine, and move the garbage in the sweeping machine to the dust box 3. The return air pipe 5 is used to guide the gas in the fan shell 1 out after the dust collector is started, so that the dust collector fan generates negative pressure in the dust box 3, and the garbage can enter the dust box 3 through the dust suction pipe 4.

[0058] By arranging the dust collector fan as described above in the dust collector base station, and further arranging the dust box 3, the dust suction pipe 4 and the return air pipe 5, one end of the dust collector fan is in communication with the dust box 3, and the other end is in communication with the return air pipe 5. The dust suction pipe 4 is arranged on the dust box 3 and in communication with the dust box 3. In this way, the dust collector fan can generate negative pressure in the dust box 3, and the garbage can enter the dust box 3 through the dust suction pipe 4. The return air pipe 5 can discharge the gas in the dust collector fan, so that the dust collector fan can work normally.

[0059] Reference Figures 9 to 12 As shown, in some embodiments, the dust box 3 has a rectangular structure, and the length direction of the dust box 3 is consistent with the air blowing direction of the fan body 6.

Alternatively, the air blowing direction of the fan body 6 can be vertical, one end of the dust box 3 is connected with the dust collector fan, and the dust box 3 can be located above the dust collector fan.

[0060] By arranging the dust box 3 to have a rectangular structure, and arranging the length direction of the dust box 3 to be consistent with the air blowing direction of the fan body 6, when the dust collector fan is started, the air in the dust box 3 can quickly pass through the fan body 6 and enter the fan inner shell 2, so as to shorten the time for forming negative pressure in the dust box 3, thereby improving the working efficiency of the dust collector base station.

[0061] Referring to Figures 9 to 12 As shown in some embodiments, one end of the dust suction pipe 4 is in communication with the side surface of the dust box 3, and the other end is adapted to be in communication with the garbage box of the sweeper, and specifically, a connecting hole can be formed on the side surface of the dust box 3, one end of the dust suction pipe 4 is inserted into the connecting hole, and the dust suction pipe 4 and the dust box 3 are connected by sealing glue, and a buckle can be provided on the other end of the dust suction pipe 4, a transfer hole is provided on the garbage box of the sweeper, a clamping groove is provided on the transfer hole, the dust suction pipe 4 is inserted into the transfer hole, the buckle and the clamping groove are clamped, the other end of the dust suction pipe 4 is in communication with the garbage box of the sweeper, and of course, a clamping groove can be provided on the garbage box of the sweeper, a rotating window is provided at the bottom of the clamping groove, a rubber sealing pad is provided on the end of the dust suction pipe 4, one end of the dust suction pipe 4 is inserted into the clamping groove, the end of the dust suction pipe 4 abuts against the bottom of the clamping groove, and the dust suction pipe 4 is in communication with the garbage box of the sweeper.

[0062] By setting one end of the dust suction pipe 4 in communication with the side surface of the dust box 3 and the other end in communication with the garbage box of the sweeper, when the dust collector fan is started, negative pressure is formed in the dust box 3, and the garbage in the garbage box of the sweeper enters the dust box 3 under the action of atmospheric pressure through the dust suction pipe 4, thereby achieving garbage transfer.

[0063] Referring to Figures 9 to 12 As shown in some embodiments, one end of the dust suction pipe 4 is in communication with the side surface of the dust box 3, and the other end is adapted to be in communication with the garbage box of the sweeper, and specifically, a connecting hole can be formed on the side surface of the dust box 3, one end of the dust suction pipe 4 is inserted into the connecting hole, and the dust suction pipe 4 and the dust box 3 are connected by sealing glue, and a buckle can be provided on the other end of the dust suction pipe 4, a transfer hole is provided on the garbage box of the sweeper, a clamping groove is provided on the transfer hole, the dust suction pipe 4 is inserted into the transfer hole, the buckle and the clamping groove are clamped, the other end of the dust suction pipe 4 is in communication with the garbage box of the sweeper, and of course, a clamping groove can be provided on the garbage box of the sweeper, a rotating window is provided at the bottom of the clamping groove, a rubber sealing pad is provided on the end of the dust suction pipe 4, one end of the dust suction pipe 4 is inserted into the clamping groove, the end of the dust suction pipe 4 abuts against the bottom of the clamping groove, and the dust suction pipe 4 is in communication with the garbage box of the sweeper.
