[0082] On the one hand, if Figure 1 As shown, an embodiment of the present invention provides an air outlet guide member for a vacuum cleaner, wherein the air outlet guide member 2 is arranged in a housing 1 of the vacuum cleaner (see 2 to 3). Figure 4 ); the air outlet guide 2 has a receiving cavity for receiving the airflow generator 3 and an air inlet 2a and at least one exhaust duct 2b respectively connected to the receiving cavity. Figure 2 and Figure 3 As shown, the air inlet 2a is connected to the exhaust port 41a of the separation component 4 of the vacuum cleaner, and the air inlet 2a is also in contact with the air intake port 3a of the airflow generator 3; the exhaust duct 2b extends from the airflow generator 3 to the outer shell 1 and is aligned with the air outlet 1a of the outer shell 1 and the exhaust port 3b of the airflow generator 3.

[0083] The air outlet guide member of the vacuum cleaner described above, the exhaust duct 2b of the air outlet guide member 2 is connected between the exhaust port 3b of the airflow generator 3 and the air outlet 1a of the outer shell 1, so that the gas exhausted by the airflow generator 3 can be directly discharged from the air outlet 1a of the outer shell 1 through the exhaust duct 2b of the air outlet guide member 2. Compared with the gas exhausted by the airflow generator 3 in the prior art and discharged from the bottom of the dust cup 5, the air outlet guide member of the present invention can ensure that the dust cup 5 is not blown away by the gas exhausted by the airflow generator 3.

[0084] like Figure 2 and Figure 3As shown, in some embodiments of the present invention, the number of exhaust air ducts 2b is multiple, and the multiple exhaust air ducts 2b are evenly spaced along the circumferential direction; the gap between each two adjacent exhaust air ducts 2b is used to allow the dust discharge port 41b of the corresponding separator 41 in the separation component 4 to extend into the dust cup 5 of the vacuum cleaner, wherein the dust cup 5 is docked with the housing 1. It can be understood that the separation component 4 is installed in the inner cavity of the housing 1. In the vacuum cleaner as described above, the multiple exhaust ducts 2b of the air outlet guide 2 are distributed along the circumferential direction, and each exhaust duct 2b is connected between the exhaust port 3b of the airflow generator 3 and the air outlet 1a of the outer shell 1, so that the gas discharged from the airflow generator 3 can be directly discharged from the air outlet 1a of the outer shell 1 through the exhaust duct 2b of the air outlet guide 2, that is, across the separator 41. Compared with the prior art in which the gas discharged from the airflow generator 3 is discharged from the bottom of the dust cup 5, the vacuum cleaner of the present invention not only has a greatly shortened length of the exhaust duct 2b, which is beneficial to the discharge of gas and can ensure that the vacuum cleaner has greater suction; in addition, it can also ensure that the internal structure of the vacuum cleaner is compact.

[0085] Further, in some embodiments of the present invention, Figure 1 As shown, the air outlet guide 2 includes: an inner shell 21 with an air inlet 2a, an outer shell 22 mounted on the outside of the inner shell 21, and a plurality of ventilation bodies 23 distributed at intervals along the circumferential direction; each ventilation body 23 is connected between the inner shell 21 and the outer shell 22, and the inner cavity of each ventilation body 23 constitutes an exhaust duct 2b; the airflow generator 3 is arranged in the inner shell 21.

[0086] Optionally, the inner shell 21 and the outer shell 22 may be respectively configured as cylindrical structures.

[0087] Specifically in some embodiments of the present invention, Figure 2 As shown, the outer contour of the dust discharge end of each separator 41 is a conical structure, and the diameter of the conical structure gradually decreases from the outer shell 1 to the dust cup 5; the inner cavity of each ventilation body 23 has a circumferential length that gradually decreases from the outer shell 1 to the dust cup 5. In this way, the inner cavity shape of the ventilation body 23 can be set according to the shape of the separator 41, so that the width of the exhaust duct 2b of the air outlet guide 2 is the largest, which is conducive to the gas discharged by the airflow generator 3 to be discharged to the outside of the vacuum cleaner without resistance. It should be noted that the dust discharge end of the separator 41 refers to the end of the separator 41 close to the dust cup 5.

[0088] Specifically, Figure 2As shown, each separator 41 in the separation assembly 4 includes a separation body 411 and a cover body 412. The separation body 411 is provided with an exhaust port 41a, a dust exhaust port 41b and an inlet 41c. The cover body 412 is provided with a first opening communicating with the exhaust port 41a, a second opening communicating with the inlet 41c and a third opening communicating with the inner cavity of the separation body 411. The separation bodies 411 of each separator 41 are integrated together through a first fixing ring 414, and the cover bodies 412 of each separator are integrated together through a second fixing ring 415. Figure 2 and Figure 3 As shown, a third sealing member 63 (eg, a sealing rubber ring) is provided between the second fixing ring 415 and the exhaust port 41 a and the inlet 41 c of each separation body 411 .

[0089] Specifically in some embodiments of the present invention, Figure 1 As shown, the connection between one port of each ventilating body 23 and the inner shell 21 is smoothly transitioned, and the connection between the other port of each ventilating body 23 and the outer shell 22 is smoothly transitioned. In this way, the resistance of the exhaust air duct 2b to the gas flowing through can be reduced, thereby improving the suction strength of the airflow generator 3. Among them, one port of each ventilating body 23 is integrally formed with the inner shell 21, and the connection between the two is set to an arc structure; the other port of each ventilating body 23 is integrally formed with the outer shell 22, and the connection between the two is set to an arc structure.

[0090] Optionally, each ventilating body 23 extends in the radial direction of the inner shell 21 to shorten the length of each exhaust air duct 2b.

[0091] Optionally, the number of ventilating bodies 23 is 10 to 14, for example, 12. It should be noted that the gap between two adjacent ventilating bodies 23 can allow the dust outlet 41b of one separator 41 to pass through, or the dust outlet 41b of multiple adjacent (for example, two, three, four, etc.) separators 41 to pass through.

[0092] Alternatively, if Figure 2 and Figure 3 As shown, the outer contour of the dust discharge end of each separator 41 is a conical structure, and the diameter of the conical structure gradually decreases from the housing 1 to the dust cup 5; Figure 1 As shown, the end of the inner shell 21 away from the dust cup 5 protrudes from the outer shell 22, and the outer diameter of the end of the inner shell 21 away from the dust cup 5 gradually decreases from the outer shell 1 to the dust cup 5. In this way, the internal structure of the vacuum cleaner can be made more compact.

[0093] Furthermore, if Figure 2 and Figure 3As shown, in some embodiments of the present invention, a first seal 61 is provided between the first edge 221 of the outer shell 22 away from the dust cup 5 and the outer shell 1; a second seal 62 is provided between the second edge 222 of the outer shell 22 close to the dust cup 5 and the dust cup 5. In this way, the first seal 61 can prevent the outside air from flowing into the outer shell 1 through the air outlet 1a of the outer shell 1, and the second seal 62 can prevent the outside air from flowing into the dust cup 5 through the air outlet 1a of the outer shell 1.

[0094] Specifically in some embodiments of the present invention, Figure 3 As shown, the first sealing member 61 includes: a mounting wall 61a and a sealing wall 61b connected to each other, the distance between the mounting wall 61a and the sealing wall 61b gradually increases from the housing 1 to the dust cup 5; the mounting wall 61a is arranged on the first edge 221 along the vertical direction, and the sealing wall 61b is used to seal the gap between the outer shell 22 and the outer shell 1. In this way, when the gas flows out from the exhaust air duct 2b, pressure can be applied to the sealing wall 61b of the first sealing member 61, so that the sealing wall 61b of the first sealing member 61 is fully deformed, and then can be sealed against the inner wall of the outer shell 1, and the gap between the outer shell 22 and the outer shell 1 can be effectively sealed.

[0095] Optionally, the first sealing member 61 may be a sealing rubber ring with an inverted V-shaped cross section.

[0096] Optionally, a mounting groove is provided on the first edge 221, and the mounting wall 61a of the first sealing member 61 is placed in the mounting groove, so that the replacement of the first sealing member 61 is facilitated.

[0097] Optionally, the second sealing member 62 may be an annular sealing rubber ring.

[0098] Specifically in some embodiments of the present invention, at least one annular protrusion is sequentially arranged from the inside to the outside on the wall of the second edge 222 facing the dust cup 5; each annular protrusion is pressed against the second sealing member 62. In this way, the second edge 222 of the outer shell 22 can effectively press the second sealing member 62 with the annular protrusion to improve the sealing performance of the second sealing member 62.

[0099] On the other hand, Figure 2 and Figure 3 As shown, the present invention also provides a vacuum cleaner, which includes: a shell 1, an airflow generator 3, a separation component 4, a dust cup 5 and an air outlet guide 2 as described in any one of the above items; the air outlet guide 2 is arranged in the shell 1; the airflow generator 3 is arranged in the air outlet guide 2; the dust cup 5 is connected to the shell 1; the separation component 4 is arranged in the shell 1 or in the dust cup 5.

[0100] In the vacuum cleaner described above, the exhaust duct of the air outlet guide is connected between the exhaust port of the air flow generator and the air outlet of the outer shell, so that the gas exhausted by the air flow generator can be directly discharged from the air outlet of the outer shell through the exhaust duct of the air outlet guide. Compared with the air flow generator in the prior art that discharges the gas from the bottom of the dust cup, the vacuum cleaner of the present invention can ensure that the dust cup is not blown away by the gas exhausted by the air flow generator 3.

[0101] In some embodiments of the present invention, Figures 2 to 3 As shown, the vacuum cleaner further includes: a blocking member 7 disposed between the housing 1 and the air outlet guide 2; the blocking member 7 is provided with a vent 7a connected to the air outlet 1a and the exhaust air duct 2b of the air outlet guide 2. In this way, foreign matter (such as screws) can be prevented from falling into the airflow generator 3 through the air outlet 1a of the housing 1 and the exhaust air duct 2b, thereby preventing the airflow generator 3 from being damaged.

[0102] Optionally, the blocking member 7 may be an annular filter cotton, and the blocking member 7 may be placed in a clamping cavity formed by the outer shell 22 and the inner wall of the outer shell 1 .

[0103] like Figure 2 and Figure 3 As shown, in some embodiments of the present invention, a plurality of exhaust ducts 2b are provided, and the plurality of exhaust ducts 2b are evenly spaced along the circumferential direction; the separation component is provided in the outer shell 1 4, and the plurality of separators 41 of the separation component 4 are distributed around the airflow generator 3; wherein the dust exhaust port 41b of each separator 41 passes through the gap between the corresponding two adjacent exhaust ducts 2b and extends into the dust collecting cup 5. In the vacuum cleaner as described above, the multiple exhaust ducts 2b of the air outlet guide 2 are distributed along the circumferential direction, and each exhaust duct 2b is connected between the exhaust port 3b of the airflow generator 3 and the air outlet 1a of the outer shell 1, so that the gas discharged from the airflow generator 3 can be directly discharged from the air outlet 1a of the outer shell 1 through the exhaust duct 2b of the air outlet guide 2, that is, across the separator 41. Compared with the prior art in which the gas discharged from the airflow generator 3 is discharged from the bottom of the dust cup 5, the vacuum cleaner of the present invention not only has a greatly shortened length of the exhaust duct 2b, which is beneficial to the discharge of gas and can ensure that the vacuum cleaner has greater suction; in addition, it can also ensure that the internal structure of the vacuum cleaner is compact.

[0104] like Figure 2 As shown, in some embodiments of the present invention, the dust cup 5 has an air inlet 5a, and a gas channel is formed between the air inlet 5a and the air inlet 41c of each separator 41 (see Figure 4); the vacuum cleaner further comprises: a dust collecting part 8 located in the dust collecting cup 5, the inlet of the dust collecting part 8 is communicated with the dust exhaust port 41b of each separator 41, and the outlet of the dust collecting part 8 is attached to the bottom wall of the dust collecting cup 5. It should be noted that there is a gap between the top opening of the dust collecting cup 5 and the inlet of the dust collecting part 8, and the gap is communicated with the gap between two adjacent exhaust air ducts 2b in the air outlet guide 2, so that a gas channel is formed between the air inlet 5a of the dust collecting cup 5 and the air inlet 41c of the separator 41.

[0105] When applied, such as Figure 4 As shown, the external dust-containing air first enters the dust cup 5 through the air inlet 5a of the dust cup 5, and then flows into the separation component 4 through the gas channel formed between the air inlet 5a and the air intake port 41c of the separator 41. After the external dust-containing air is separated by the separation component 4, the dust in the external dust-containing air is discharged into the dust cup 5 through the dust exhaust port 41b of the separator 41. At the same time, the separated air enters the airflow generator 3 through the exhaust port 41a of the separator 41, and then is directly discharged to the outside of the housing 1 through the exhaust port 3b of the airflow generator 3 and the exhaust duct 2b of the air outlet guide 2. It should be noted that Figure 4 The arrows in the figure indicate the direction of gas flow.

[0106] Optionally, the dust collecting part 8 is configured as a funnel structure.

[0107] Optionally, a fourth sealing member 64 may be installed at the outlet of the dust collecting portion 8 (see Figure 3 ), so that the outlet of the dust collecting part 8 is sealed and attached to the bottom of the dust collecting cup 5. The fourth sealing member 64 can be a box-shaped structure with an opening, and the material can be rubber.

[0108] Furthermore, if Figure 2 and Figure 3 As shown, in some embodiments of the present invention, the vacuum cleaner further comprises: a cyclone 9 located in the dust cup 5, the air inlet of the cyclone 9 is connected to the air inlet 5a, the air outlet of the cyclone 9 is connected to the exhaust port 41a of each separator 41, and is connected to the outer wall of at least one separator 41; the inlet end of the dust collecting part 8 is located in the cyclone 9, and the outlet end of the dust collecting part 8 is sealed through the bottom of the cyclone 9. In this way, the cyclone 9 can perform initial dust separation on the air entering the dust cup 5 of the vacuum cleaner.

[0109] Optionally, the air inlet of the cyclone 9 is tangentially distributed relative to the airflow discharged from the air inlet 5a of the dust cup 5. The air inlet of the cyclone 9 may be composed of a plurality of strip-shaped through holes.
