[0027] The technical solution of the utility model will be further described below in conjunction with embodiments and drawings.

[0028] Please also read Figure 1 and Figure 2 The embodiment of the utility model discloses a vacuum cleaner, including a vacuum cleaner body and a cyclone separation and filtering structure, wherein the cyclone separation and filtering structure is arranged on the vacuum cleaner body. The cyclone separation and filtering structure of the present scheme includes a filter element 1, an air outlet pipe 2 and a first interception component 3, wherein one end of the air outlet pipe 2 is connected to one end of the filter element 1, and the first interception component 3 is arranged on the air outlet pipe 2, wherein the filter element 1 and the first interception component 3 together form an inverted cone-shaped cyclone separation and filtering structure, wherein an interception portion 31 is arranged on the outer side of the first interception component 3, and the interception portion 31 is used to prevent the sucked garbage from moving in the direction toward the filter element 1. With such a design, since the filter element 1 and the first intercepting component 3 jointly form an inverted cone-shaped cyclone separation and filtration structure, when the vacuum cleaner is in the vacuuming mode, hair is entangled on the first intercepting component 3, and the first intercepting component 3 can effectively block the hair from moving toward the filter element 1, thereby preventing the filter element 1 from being affected by the entanglement of hair; and, since the hair is gathered together after being clumps on the first intercepting component 3, the force of the wind when the vacuum cleaner is in the self-cleaning mode increases, which facilitates the hair to be detached downward. In addition, the intercepting portion 31 is used to block the inhaled garbage from moving in the direction toward the filter element 1, and the garbage refers to strip-shaped garbage such as hair and wool, thereby further improving the hair interception effect of the first intercepting component 3.

[0029] Further, the intercepting portion 31 is an inverted sawtooth in a direction away from the filter element 1. The inverted sawtooth can better hook the hair. It is understandable that the intercepting portion 31 can also be a hook, etc., which is not limited here.

[0030] In some embodiments, in order to further improve the hair interception effect of the first interception component 3, a first protrusion 21 is provided on the end surface of the air outlet duct 2 away from the filter element 1, and the first protrusion 21 can better intercept hair.

[0031] Furthermore, the first protrusion 21 and the interception portion 31 are connected to each other, and there is a smooth transition between the first protrusion 21 and the interception portion 31. With such a design, the process is simple and it is possible to avoid injury to the hand during replacement.

[0032] Furthermore, the first protrusion 21 is bent along the axial direction toward the air outlet pipe 2. With such a design, since the first protrusion 21 is bent inward, it is easy to grasp the hair, and it can avoid hurting the hand during replacement.

[0033] Similarly, in order to further improve the hair interception effect of the first interception component 3, a second protrusion 32 is provided on the end surface of the first interception component 3 away from the filter element 1, and the second protrusion 32 can better catch the hair. Preferably, the first protrusion 21 and the second protrusion 32 are both inverted teeth, so that they have a better interception effect.

[0034] In order for the first interception component 3 to effectively gather hair, there are at least two first interception components 3, and at least two first interception components 3 are arranged at intervals along the circumference of the air outlet pipe 2. With such a design, at least two first interception components 3 can effectively gather hair to the bottom of the cyclone separation and filtration structure, and at the same time, can ensure efficient dust and gas separation, and can significantly improve the cleaning of garbage, especially hair. This embodiment is illustrated by taking four first interception components 3 as an example. It can be understood that in other embodiments, the first interception components 3 can also be two, three, five or more than five, which is not limited here.

[0035] In some embodiments, the angle between the filter element 1 and the axis direction of the cyclone separation filter structure is α, and the angle between the first intercepting component 3 and the axis direction of the cyclone separation filter structure is β, α≤β. With such a design, since the angle between the first intercepting component 3 and the axis direction of the cyclone separation filter structure is greater than or equal to the angle between the filter element 1 and the axis direction of the cyclone separation filter structure, the hair is guided away from the filter element 1, which helps to intercept the hair in the dust suction mode and to separate the hair in the self-cleaning mode.

[0036] Preferably, the angle between the first intercepting component 3 and the axial direction of the cyclone separation filter structure is greater than the angle between the filter element 1 and the axial direction of the cyclone separation filter structure, that is, α<β, which can facilitate the separation of hair.

[0037] Furthermore, the range of the angle between the filter element 1 and the axial direction of the cyclone separation filter structure is 1°≤α≤10°. Wherein, α can be 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, etc., and the present embodiment takes the angle α between the filter element 1 and the axial direction of the cyclone separation filter structure as 5° as an example.

[0038] Further, the angle between the first intercepting component 3 and the axial direction of the cyclone separation and filtering structure is in the range of 1°≤β≤45°. Wherein, β can be 1°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, etc., and this embodiment takes the angle β between the first intercepting component 3 and the axial direction of the cyclone separation and filtering structure as 5° as an example.

[0039] In some embodiments, in order for the first interception component 3 to effectively intercept hair, the length of the filter 1 is L1, the length of the first interception component 3 is L2, and 1 / 2L1≤L2, thereby increasing the interception surface of the intercepted hair, and further improving the interception effect of the hair. Among them, the length L1 of the filter 1 and the length L2 of the first interception component 3 are both the lengths in the inclined direction or the lengths in the vertical direction. This embodiment takes the example that the length L1 of the filter 1 and the length L2 of the first interception component 3 are both the lengths in the vertical direction.

[0040] In some embodiments, considering that some hair may pass through the first interception component 3 and entangle the filter element 1, the hair may be adsorbed by static electricity, and even some hair may enter the mesh of the filter element 1 and block the mesh, the cyclone separation filter structure further includes a second interception component 11, and the second interception component 11 is arranged on the filter element 1. With such a design, the second interception component 11 can effectively prevent the hair from being directly entangled on the filter element 1.

[0041] In order for the first interception component 3 to effectively gather hair, there are at least three second interception components 11, and at least three second interception components 11 are arranged at intervals along the circumference of the filter element 1. This embodiment takes eight second interception components 11 as an example, and it can be understood that in other embodiments, the number of second interception components 11 can also be three, four, five, six, seven, etc., which is not limited here.

[0042] Furthermore, the angle between the second intercepting component 11 and the axial direction of the cyclone separation and filtering structure is γ, 1°≤γ≤10°, wherein γ can be 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, 10°, etc., which is not limited here.

[0043] Furthermore, the cyclone separation and filtering structure further includes a rotating air inlet platform 12, which is disposed on the filter element 1 and is formed with a rotating section 121 facing the second intercepting component 11, and one end of a portion of the second intercepting component 11 extends to the rotating section 121 of the rotating air inlet platform 12. With such a design, since the rotating section 121 of the rotating air inlet platform 12 can form a downward-pressing cyclone, the hair entangled in the second intercepting component 11 is pressed downward, which facilitates the shedding of the hair.

[0044] The utility model provides a vacuum cleaner, which comprises a cyclone separation and filtering structure including a filter element 1, an air outlet pipe 2 and a first interception component 3, wherein one end of the air outlet pipe 2 is connected to one end of the filter element 1, the first interception component 3 is arranged on the air outlet pipe 2, the filter element 1 and the first interception component 3 together form an inverted cone-shaped cyclone separation and filtering structure, wherein an interception portion 31 is arranged on the outer side of the first interception component 3, and the interception portion 31 is used to block the sucked garbage from moving in the direction toward the filter element 1. With such a design, since the filter element 1 and the first interception component 3 together form an inverted cone-shaped cyclone separation and filtering structure, when the vacuum cleaner is in the dust suction mode, hair is entangled on the first interception component 3, and the first interception component 3 can effectively block the hair from moving in the direction of the filter element 1, thereby preventing the filter element 1 from affecting the use due to the entanglement of the hair; and since the hair is gathered together after being clumped on the first interception component 3, when the vacuum cleaner is in the self-cleaning mode, the force is increased when the wind blows, which facilitates the hair to be separated downward. In addition, the interception portion 31 is used to prevent the sucked garbage from moving in the direction toward the filter 1 , and the garbage refers to strip-shaped garbage such as hair and wool, thereby further improving the hair interception effect of the first interception component 3 .

This article uses individual examples to illustrate the principle and implementation method of the present invention. The description of the above embodiments is only used to help understand the cyclone separation filter structure and the dust collector of the present invention and its core idea; at the same time, for general technical personnel in this field, according to the idea of ​​the present invention, there will be changes in the specific implementation method and application scope. In summary, the content of this specification should not be understood as a limitation on the present invention.
