In contrast, when an element is referred to as being "directly connected" to another element, there are no intervening elements present. The terms "vertical," "horizontal," "left," "right," and the like as used herein are for illustrative purposes only.

In the description of the present invention, it is to be understood that the terms "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "top," "bottom," "inner," "outer," and the like are used in the orientations and positional relationships indicated in the drawings for convenience in describing the present invention and for simplicity in description, and are not intended to indicate or imply that the referenced devices or elements must have a particular orientation, be constructed in a particular orientation, and be operated in a particular manner and are not to be construed as limiting the present invention.

In one aspect, as shown in fig. 1, an embodiment of the present invention provides an outlet guide 2 of a vacuum cleaner, where the outlet guide 2 is disposed in a housing 1 of the vacuum cleaner (see fig. 2 to 4); the air outlet guide 2 is provided with a containing cavity for containing the airflow generator 3, an air inlet 2a and at least one air exhaust duct 2b which are respectively communicated with the containing cavity. As shown in fig. 2 and 3, the air inlet 2a is communicated with the air outlet 41a of the separating assembly 4 of the vacuum cleaner, and the air inlet 2a is attached to the air inlet 3a of the airflow generator 3; the air exhaust duct 2b extends from the airflow generator 3 to the housing 1 and is aligned with the air outlet 1a of the housing 1 and the air outlet 3b of the airflow generator 3.

In the air outlet guide piece of the dust collector, the air exhaust duct 2b of the air outlet guide piece 2 is communicated between the air exhaust port 3b of the airflow generator 3 and the air outlet 1a of the shell 1, so that the air discharged by the airflow generator 3 can be directly discharged from the air outlet 1a of the shell 1 through the air exhaust duct 2b of the air outlet guide piece 2, and compared with the condition that the air discharged by the airflow generator 3 in the prior art is discharged from the bottom of the dust collection cup 5, the air outlet guide piece of the dust collector can ensure that the dust collection cup 5 is not blown off by the air discharged by the airflow generator 3.

As shown in fig. 2 and 3, in some embodiments of the present invention, the number of the exhaust air ducts 2b is multiple, and the exhaust air ducts 2b are uniformly distributed at intervals along the circumferential direction; the gap between every two adjacent air exhaust ducts 2b is used for enabling the dust exhaust port 41b of the corresponding separator 41 in the separating assembly 4 to extend into the dust collecting cup 5 of the dust collector, wherein the dust collecting cup 5 is butted with the shell 1. It will be appreciated that the separator assembly 4 is mounted in the interior cavity of the housing 1. As mentioned above, the air exhaust ducts 2b of the air exhaust guide 2 are circumferentially distributed, and each air exhaust duct 2b is communicated between the air exhaust port 3b of the air flow generator 3 and the air outlet 1a of the housing 1, so that the air exhausted by the air flow generator 3 can be directly exhausted from the air outlet 1a of the housing 1 through the air exhaust duct 2b of the air exhaust guide 2, i.e. across the separator 41, compared with the prior art in which the air exhausted by the air flow generator 3 is exhausted from the bottom of the dust cup 5, the dust collector of the present invention not only shortens the length of the air exhaust duct 2b greatly, which is beneficial to the exhaust of the air, and can ensure that the dust collector has a larger suction force; in addition, the internal structure of the dust collector can be ensured to be compact.

Further, in some embodiments of the present invention, as shown in fig. 1, the wind outlet guide 2 includes: an inner shell 21 with an air inlet 2a, an outer shell 22 sleeved outside the inner shell 21 and a plurality of ventilation bodies 23 distributed at intervals along the circumferential direction; each ventilating body 23 is communicated between the inner shell 21 and the outer shell 22, and an inner cavity of each ventilating body 23 forms an exhaust air duct 2 b; the airflow generator 3 is arranged within the inner housing 21.

Alternatively, the inner case 21 and the outer case 22 may be provided in a cylindrical structure, respectively.

In particular, in some embodiments of the invention, as shown in fig. 2, the dust discharge end of each separator 41 is profiled in a cone-like configuration, the diameter of the cone-like configuration decreasing from the housing 1 to the dirt cup 5; the length of the inner cavity of each ventilating body 23 in the circumferential direction is gradually reduced from the housing 1 to the dust cup 5. Thus, the shape of the inner cavity of the ventilating body 23 can be set according to the shape of the separator 41, so that the width of the air exhaust duct 2b of the air exhaust guide 2 is the largest, which is beneficial for the air exhausted by the airflow generator 3 to be discharged to the outside of the dust collector without resistance. It should be noted that the dust discharge end of the separator 41 refers to the end of the separator 41 near the dirt cup 5.

Specifically, as shown in fig. 2, each separator 41 in the separation assembly 4 includes a separation main body 411 and a cover 412, the separation main body 411 is provided with an air outlet 41a, a dust outlet 41b and an inlet 41c, the cover 412 is provided with a first opening communicated with the air outlet 41a, a second opening communicated with the inlet 41c and a third opening communicated with an inner cavity of the separation main body 411; the separating body 411 of each separator 41 is integrated together by a first fixing ring 414, and the cover 412 of each separator is integrated together by a second fixing ring 415. As shown in fig. 2 and 3, a third sealing member 63 (e.g., a sealing rubber ring) is disposed between the second fixing ring 415 and the air outlet 41a and the air inlet 41c of each of the separating bodies 411.

In particular, in some embodiments of the present invention, as shown in fig. 1, a junction between one port of each vent body 23 and the inner housing 21 is smoothly transitioned, and a junction between the other port of each vent body 23 and the outer housing 22 is smoothly transitioned. Thus, the resistance of the air exhaust duct 2b to the passing air can be reduced, and the suction strength of the airflow generator 3 can be improved. Wherein, a port of each ventilating body 23 and the inner shell 21 are integrally formed, and the connection part between the two is set into an arc structure; the other port of each vent body 23 is integrally formed with the outer housing 22, and the junction between the two is provided in an arc-shaped configuration.

Alternatively, each of the ventilating bodies 23 extends in the radial direction of the inner case 21 to make the length of each of the exhaust air ducts 2b shorter.

Alternatively, the number of the vent bodies 23 is 10 to 14, and for example, 12 vent bodies may be provided. It should be noted that the gap between two adjacent ventilating bodies 23 may allow the dust discharge port 41b of one separator 41 to pass through, or may allow the dust discharge ports 41b of a plurality of adjacent (for example, two, three, four, etc.) separators 41 to pass through.

Alternatively, as shown in fig. 2 and 3, the dust discharging end of each separator 41 is profiled in a cone-shaped configuration, the diameter of which gradually decreases from the housing 1 to the dust cup 5; as shown in figure 1, an end of the inner housing 21 remote from the dust cup 5 protrudes the outer housing 22, and an outer diameter of the end of the inner housing 21 remote from the dust cup 5 is gradually reduced from the outer housing 1 to the dust cup 5. Thus, the internal structure of the dust collector can be more compact.
