[0026] The technical solution of the utility model will be further described below in conjunction with embodiments and drawings.

[0027] 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 blocking component 3, wherein one end of the air outlet pipe 2 is connected to one end of the filter element 1, and the first blocking component 3 is arranged on the air outlet pipe 2, wherein the filter element 1 and the first blocking component 3 together form an inverted cone-shaped cyclone separation and filtering structure, and such a design method is adopted, since the filter element 1 and the first 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 first blocking component 3 can block dust, and the first blocking component 3 can effectively block dust and hair from moving toward the filter element 1, which is conducive to the deposition of garbage at the bottom of the dust cup, and avoids the filter element 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 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.

[0028] In order for the first blocking component 3 to effectively gather hair, there are at least two first blocking components 3, and at least two first blocking components 3 are arranged at intervals along the circumference of the air outlet pipe 2. With such a design, at least two first 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 four first blocking components 3 as an example. It can be understood that in other embodiments, two, three, five or more first blocking components 3 can also be used, which is not limited here.

[0029] In some embodiments, the angle between the filter element 1 and the axial direction of the cyclone separation filter structure is α, and the angle between the first blocking component 3 and the axial direction of the cyclone separation filter structure is β, α≤β. With such a design, since the angle between the first blocking component 3 and the axial direction of the cyclone separation filter structure is greater than or equal to the angle between the filter element 1 and the axial 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.

[0030] Preferably, the angle between the first blocking component 3 and the axial direction of the cyclone separation and filtering structure is greater than the angle between the filter element 1 and the axial direction of the cyclone separation and filtering structure, that is, α<β, which can facilitate the separation of hair.

[0031] 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.

[0032] Further, the angle between the first blocking 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 blocking component 3 and the axial direction of the cyclone separation and filtering structure as 5° as an example.

[0033] In some embodiments, in order for the first blocking component 3 to effectively intercept hair, the length of the filter 1 is L1, the length of the first 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 1 and the length L2 of the first 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 1 and the length L2 of the first blocking component 3 are both the lengths in the vertical direction.

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

[0035] Further, the blocking 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 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 component 3, a first protrusion 21 is provided on the end surface of the air outlet 2 away from the filter element 1, and the first protrusion 21 can better intercept hair. Similarly, in order to further improve the hair interception effect of the first blocking component 3, a second protrusion 32 is provided on the end surface of the first blocking component 3 away from the filter element 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, in order to form an inverted cone after the first blocking component 3 is installed on the air outlet pipe 2, the air outlet pipe 2 is a circular air outlet pipe, and the first blocking component 3 is a trapezoidal blocking component. It is understandable that in other embodiments, the air outlet pipe 2 can be an inverted cone air outlet pipe, and the first blocking component 3 can be a rectangular design, which is not limited here.

[0038] Furthermore, the first blocking component 3 and the air outlet pipe 2 are integrally formed. With such a design, the process is simple and the production cost is low.

[0039] In some embodiments, considering that some hair may pass through the first blocking 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 blocking component 11, and the second blocking component 11 is arranged on the filter element 1. With such a design, the second blocking component 11 can effectively prevent the hair from being directly entangled on the filter element 1.

[0040] In order for the first blocking component 3 to effectively gather hair, there are at least three second blocking components 11, and at least three second blocking components 11 are arranged at intervals along the circumference of the filter element 1. This embodiment takes eight second blocking components 11 as an example. With such a design, the filter element 1 can have a better anti-hair entanglement effect without occupying the effective air inlet area of ​​the filter element 1. It can be understood that in other embodiments, the number of second blocking components 11 can also be three, four, five, six, seven, etc., which is not limited here.

[0041] Furthermore, the angle between the second 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.

[0042] Furthermore, the cyclone separation and filtering structure further includes a spiral air inlet platform 12, which is disposed on the filter element 1 and is formed with a spiral cut surface 121 facing the second blocking component 11, and one end of a portion of the second blocking component 11 extends to the spiral cut surface 121 of the spiral air inlet platform 12. With such a design, since the spiral cut surface 121 of the spiral air inlet platform 12 can form a downward-pressing cyclone, the hair wrapped around the second blocking component 11 is pressed downward, which facilitates the shedding of the hair.

[0043] The utility model provides a vacuum cleaner, which includes a cyclone separation and filtering structure including a filter element 1, an air outlet pipe 2 and a first blocking component 3, wherein one end of the air outlet pipe 2 is connected to one end of the filter element 1, and the first blocking component 3 is arranged on the air outlet pipe 2, and the filter element 1 and the first blocking component 3 together form an inverted cone-shaped cyclone separation and filtering structure. With such a design, since the filter element 1 and the first 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 first blocking component 3 can block dust, and the first blocking component 3 can effectively block dust and hair from moving toward the filter element 1, which is conducive to the deposition of garbage at the bottom of the dust cup, and avoids the filter element 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 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.

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.
