[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 component 1 and at least three first blocking components 11, wherein the at least three first blocking components 11 are arranged at intervals along the circumference of the filter component 1, wherein the filter component 1 is an inverted cone structure. With such a design, since the filter component 1 is an inverted cone structure, it is conducive to the deposition of garbage at the bottom of the filter component 1. Since hair may be adsorbed by electrostatic electricity, and even part of the hair may enter the mesh of the filter component 1 and block the mesh, the first blocking component 11 is arranged on the filter component 1, which can effectively prevent the hair from being directly entangled on the filter component 1, thereby preventing the filter component 1 from being unable to be cleaned due to the entanglement of the hair, and even affecting its use in serious cases.

[0029] Furthermore, the cyclone separation and filtering structure further includes a spiral air inlet platform 12, which is disposed on the filtering component 1 and is formed with a spiral section 121 facing the first blocking component 11, and one end of a portion of the first blocking component 11 extends to the spiral section 121 of the spiral air inlet platform 12. With such a design, since the spiral section 121 of the spiral air inlet platform 12 can form a downward-pressing cyclone, the hair wrapped around the first blocking component 11 is pressed downward, which facilitates the shedding of the hair.

[0030] Furthermore, there are eight first blocking components 11 . With such a design, the filter component 1 can have a better anti-hair entanglement effect without occupying the effective air inlet area.

[0031] It is understandable that in other embodiments, the number of first blocking components 11 may be three, four, five, six, seven, etc., which is not limited here.

[0032] Furthermore, the angle between the first blocking 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.

[0033] In some embodiments, the cyclone separation and filtering structure further includes an air outlet pipe 2 and a second blocking component 3, one end of the air outlet pipe 2 is connected to one end of the filtering component 1, and the other end is extended in a direction away from the filtering component 1, the second blocking component 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 filtering component 1 and the second blocking component 3 together form an inverted cone-shaped cyclone separation and filtering structure, and adopting such a design method, since the filtering component 1 and the second blocking component 3 together form an inverted cone-shaped cyclone separation and filtering structure, when the vacuum cleaner is in the dust collection mode, the side wall surface of the second blocking component 3 can block dust, and the second blocking component 3 can effectively block dust and hair from moving in the direction of the filtering component 1, which is conducive to the deposition of garbage at the bottom of the dust cup, and avoids the filtering 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 second blocking component 3, the force of the downward airflow on the hair is increased in the self-cleaning mode of the vacuum cleaner, which is convenient for the hair to be separated downward.

[0034] In order for the second blocking component 3 to effectively gather hair, there are at least two second blocking components 3, and at least two second blocking components 3 are arranged at intervals along the circumference of the air outlet pipe 2. With such a design, at least two second blocking 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 takes the example of four second blocking components 3 as an example. It can be understood that in other embodiments, the second blocking 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 component 1 and the axis direction of the cyclone separation filter structure is α, and the angle between the second blocking 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 second blocking component 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 dust suction mode and to separate the hair in the self-cleaning mode.

[0036] Preferably, the angle between the second blocking component 3 and the axial direction of the cyclone separation filter structure is greater than the angle between the filter component 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 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.

[0038] Furthermore, the angle between the second blocking component 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 second blocking component 3 and the axial direction of the cyclone separation and filtering structure is 5°.

[0039] In some embodiments, in order for the second blocking component 3 to effectively intercept hair, the length of the filter component 1 is L1, the length of the second blocking 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 component 1 and the length L2 of the second blocking 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 component 1 and the length L2 of the second blocking component 3 are both the lengths in the vertical direction.

[0040] In some embodiments, in order to further improve the hair intercepting effect of the second blocking component 3, a blocking portion 31 is provided on the outer side of the second blocking component 3, and the blocking portion 31 is used to block the garbage entangled on the second blocking component 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 second blocking component 3.

[0041] 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.

[0042] In some embodiments, in order to further improve the hair interception effect of the second blocking component 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 second blocking component 3, a second protrusion 32 is provided on the end surface of the second blocking component 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.

[0043] The utility model provides a vacuum cleaner, which includes a filter component 1 and at least three first blocking components 11, wherein the at least three first blocking components 11 are arranged at intervals along the circumference of the filter component 1, wherein the filter component 1 is an inverted cone structure. With such a design, since the filter component 1 is an inverted cone structure, it is conducive to the deposition of garbage at the bottom of the filter component 1, and since hair may be adsorbed by static electricity, and even part of the hair may enter the mesh of the filter component 1 and block the mesh, the first blocking component 11 is arranged on the filter component 1, which can effectively prevent the hair from being directly entangled on the filter component 1, thereby preventing the filter component 1 from being unable to be cleaned due to the entanglement of hair, and even affecting its use in serious cases.
