[0027] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0028] See also Figure 1-9 The utility model discloses a dust box collector for a cleaning device, including a dust box collector body 1, on which an air inlet 11 and an air inlet 2 12 are provided. An air inlet spiral generator 13 is provided inside the dust box collector body 1 and is located on one side of the air inlet 11. The air inlet 11 is arranged at an angle, and the air inlet spiral generator 13 is provided with an air pressure wall 131 that matches the inclination of the air inlet 11.

[0029] Specifically, the air inlet 11 and the air inlet 2 12 are perpendicular to each other, and the air inlet spiral generator 13 and the air inlet 2 12 are perpendicular to each other. This design method is conducive to the air inlet spiral generator 13 converting the airflow entering from the air inlet 11 into spiral motion.

[0030] Specifically, the size of the air pressure wall 131 is larger than the size of the air inlet 11, so that the air entering from the air inlet 11 can all hit the air pressure wall 131, which is conducive to the formation of a cyclone.

[0031] Specifically, the air pressure wall 131 is in an inclined shape or an arc shape. The air pressure wall 131 can be an inclined straight surface or an inclined arc surface, which is beneficial to the formation of a cyclone.

[0032] Specifically, the end of the air inlet spiral generator 13 away from the air inlet 11 does not exceed the center line of the air inlet 2 12. Figure 5The inclined air pressure wall 131 forms a certain angle with the air inlet 11, the optimal angle range is between 21 degrees and 23 degrees, and the air inlet spiral generator 13 maintains a relative angle with the center line of the air inlet 2 12, and cannot exceed the center line, which is conducive to generating spiral wind and allowing objects to quickly enter the collection area on one side of the coarse filter 16.

[0033] Specifically, the air inlet 11 is provided at the bottom of the dust box collector body 1 , and the air inlet 2 12 is provided at one end of the dust box collector body 1 . The air inlet 2 12 is used to connect the air inlet channel pipe 17 to the host.

[0034] Specifically, the air inlet spiral generator 13 is further provided with an air inlet connecting surface 132 located on one side of the air pressure wall 131 .

[0035] Specifically, a dust box collector cover 14 is provided on one side of the dust box collector body 1, and the air pressure wall 131, the air inlet connecting surface 132, the dust box collector cover 14, and the bottom of the dust box collector body 1 are combined to form a conical air duct.

[0036] Specifically, the interior of the dust box collector body 1 is provided with a high-efficiency filter 15 located on one side of the air inlet 12 and a coarse-efficiency filter 16 located on one side of the high-efficiency filter 15. The interior of the dust box collector body 1 is provided with slots for installing the high-efficiency filter 15 and the coarse-efficiency filter 16, ensuring the assembly stability of the high-efficiency filter 15 and the coarse-efficiency filter 16.

[0037] Specifically, one end of the dust box collector body 1 is provided with an air inlet channel tube 17 connected to the second air inlet 12, and the end of the air inlet channel tube 17 away from the second air inlet 12 is provided with a host connection port 18 for connecting to the cleaning device host.

[0038] When using, refer to Figure 9, when the host connection port 18 is connected to the cleaning device host, the cleaning device host is started. Since the interior of the dust box collector body 1 is a relatively closed space, the direction of the air flow can only be from the air inlet 11 to the air inlet 2 12. When the air enters from the air inlet 11, since the air inlet connecting surface 132 of the air inlet spiral generator 13 is connected to the inner wall of the air inlet 11 and is consistent with the air inlet slope of the air inlet 11, the air flow along the air inlet spiral generator 13 and the air inlet connecting surface 132 hits the air pressure wall 131 of the air inlet spiral generator 13, thereby changing the direction of the air flow. The conical air duct composed of the vortex generator 13, the dust box collector cover 14 and the bottom of the dust box collector body 1 forms a conical design with the air inlet 11 from small to large. Under the action of the air pressure wall 131, the direction of the air flow is changed to form a spiral motion. Under the action of the air inlet 2 12, the rapid spiral airflow rolls the objects into the space on one side of the coarse filter 16. Since the air flow is a spiral motion, under the action of air pressure, it is easier to roll hair-like objects into a ball and compress them inside the dust box collector body 1, so that the internal space of the dust box collector body 1 is effectively utilized.

[0039] To sum up, the dust box collector used in the cleaning device uses a specially designed air inlet spiral generator 13 to make the air pressure wall 131, the air inlet connecting surface 132, the dust box collector cover 14 and the bottom of the dust box collector body 1 form a conical air duct, which is used in conjunction with the air inlet 1 12 perpendicular to the air inlet 1 1 and the air inlet spiral generator 13, so that the air flow forms a spiral motion after entering the conical air duct. Under the action of air pressure, it is easier to roll hair-like objects into a ball and compress them inside the dust box collector body 1, thereby improving the cleaning effect and making effective use of the internal space of the dust box collector body 1 to meet the user's needs.
