[0028] Please also read Figure 1 and Figure 2 The utility model embodiment discloses a vacuum cleaner, comprising a filter component 1, an air outlet pipe 2 and a first blocking member 3, one end of the air outlet pipe 2 is connected to one end of the filter component 1, and the first blocking member 3 is arranged on the air outlet pipe 2, and the filter component 1 and the first blocking member 3 jointly form an inverted cone-shaped cyclone separation and filtering structure; wherein, the angle between the filter component 1 and the axial direction of the cyclone separation and filtering structure is α, and the angle between the first blocking member 3 and the axial direction of the cyclone separation and filtering structure is β, α≤β. With such a design method, since the filter component 1 and the first blocking member 3 jointly form an inverted cone-shaped cyclone separation and filtering structure, when the vacuum cleaner is in the dust suction mode, the side wall surface of the first blocking member 3 can block dust, and the first blocking member 3 can effectively block dust and hair from moving toward the direction of the filter component 1, which is conducive to the deposition of garbage at the bottom of the dust cup, and avoids the filter component 1 from being unable to be cleaned due to entanglement of hair, and even affects its use in serious cases. In addition, since the hair is gathered together after being clumped on the first blocking member 3, the force of the downward airflow on the hair is increased in the self-cleaning mode of the vacuum cleaner, which facilitates the hair to fall away. In addition, since the angle between the first blocking member 3 and the axis direction of the cyclone separation filter structure is greater than or equal to the angle between the filter component 1 and the axis direction of the cyclone separation filter structure, the hair is guided away from the filter component 1, which helps to intercept the hair in the vacuum mode and to separate the hair in the self-cleaning mode.

[0029] Preferably, the angle between the first blocking member 3 and the axial direction of the cyclone separation and filtering structure is greater than the angle between the filter component 1 and the axial direction of the cyclone separation and filtering structure, that is, α<β, so that the first blocking member 3 can effectively block hair.

[0030] Furthermore, the range of the angle between the filter component 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 this embodiment takes the angle α between the filter component 1 and the axial direction of the cyclone separation filter structure as 5° as an example.

[0031] Furthermore, the angle between the first blocking member 3 and the axial direction of the cyclone separation and filtering structure is in the range of 1°≤β≤45°, where β can be 1°, 5°, 10°, 15°, 20°, 25°, 30°, 35°, 40°, 45°, etc. In this embodiment, the angle β between the first blocking member 3 and the axial direction of the cyclone separation and filtering structure is 5°.

[0032] In some embodiments, in order for the first blocking member 3 to effectively intercept hair, the length of the filter component 1 is L1, the length of the first blocking member 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 component 1 and the length L2 of the first blocking member 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 component 1 and the length L2 of the first blocking member 3 are both the lengths in the vertical direction.

[0033] In order for the first blocking member 3 to effectively gather hair, there are at least two first blocking members 3, and at least two first blocking members 3 are arranged at intervals along the circumference of the air outlet pipe 2. With such a design, at least two first blocking members 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 takes the example of four first blocking members 3 as an example. It can be understood that in other embodiments, the first blocking members 3 can also be two, three, five or more than five, which is not limited here.

[0034] In some embodiments, in order to further improve the hair intercepting effect of the first blocking member 3, a blocking portion 31 is provided on the outer side of the first blocking member 3, and the blocking portion 31 is used to block the garbage wrapped around the first blocking member 3 from moving in the direction toward the filter component 1. The garbage refers to strip-shaped garbage such as hair and wool, thereby improving the hair intercepting effect of the first blocking member 3.

[0035] Further, the blocking portion 31 is an inverted sawtooth in a direction away from the filter component 1. The inverted sawtooth can better hook the hair. It is understandable that the blocking portion 31 can also be a hook, etc., which is not limited here.

[0036] In some embodiments, in order to further improve the hair interception effect of the first blocking member 3, a first protrusion 21 is provided on the end surface of the air outlet 2 away from the filter component 1, and the first protrusion 21 can better intercept hair. Similarly, in order to further improve the hair interception effect of the first blocking member 3, a second protrusion 32 is provided on the end surface of the first blocking member 3 away from the filter component 1, and the second protrusion 32 can better clamp the hair. Preferably, the first protrusion 21 and the second protrusion 32 are both inverted teeth, so that they have a better interception effect.

[0037] In some embodiments, considering that some hair may pass through the first blocking member 3 and entangle the filter component 1, the hair may be adsorbed by static electricity, and even some hair may enter the mesh of the filter component 1 and block the mesh, the cyclone separation filter structure further includes a second blocking member 11, and the second blocking member 11 is arranged on the filter component 1. With such a design, the second blocking member 11 can effectively prevent the hair from being directly entangled on the filter component 1.

[0038] In order for the first blocking member 3 to effectively gather hair, there are at least three second blocking members 11, and at least three second blocking members 11 are arranged at intervals along the circumference of the filter component 1. This embodiment takes eight second blocking members 11 as an example, and it can be understood that in other embodiments, the number of second blocking members 11 can also be three, four, five, six, seven, etc., which is not limited here.

[0039] Furthermore, the angle between the second blocking member 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.

[0040] Furthermore, the cyclone separation and filtering structure further includes a rotating air inlet platform 12, which is disposed on the filtering component 1 and is formed with a rotating section 121 facing the second blocking member 11, and one end of a portion of the second blocking member 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 wrapped around the second blocking member 11 is pressed downward, which facilitates the shedding of the hair.

[0041] The utility model provides a vacuum cleaner, which comprises a cyclone separation and filtering structure including a filter component 1, an air outlet pipe 2 and a first blocking member 3, wherein one end of the air outlet pipe 2 is connected to one end of the filter component 1, and the other end is extended in a direction away from the filter component 1, the first blocking member 3 is arranged on the air outlet pipe 2 and its length extension direction is the same as the length extension direction of the air outlet pipe 2, the filter component 1 and the first blocking member 3 jointly form an inverted cone-shaped cyclone separation and filtering structure, and adopts such a design mode, since the filter component 1 and the first blocking member 3 jointly form an inverted cone-shaped cyclone separation and filtering structure, in the vacuum cleaner in the dust collection mode, the side wall surface of the first blocking member 3 can block dust, and the first blocking member 3 can effectively block dust and hair from moving in the direction of the filter component 1, which is conducive to the deposition of garbage at the bottom of the dust cup, and avoids the filter component 1 from being unable to be cleaned due to the entanglement of hair, and even affects its use in serious cases. In addition, since the hair is gathered together after being clumped on the first blocking member 3, the force of the downward airflow on the hair is increased in the vacuum cleaner in the self-cleaning mode, which is convenient for the hair to be separated downward. Furthermore, since the angle between the first blocking member 3 and the axial direction of the cyclone separation filter structure is greater than or equal to the angle between the filter component 1 and the axial direction of the cyclone separation filter structure, the hair is guided away from the filter component 1, thereby facilitating the interception of hair in the dust collection mode and the removal of hair in the self-cleaning mode.

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.
