When the dust collecting head 100 is working, air can flow from the suction chamber 111 to the air outlet passage 112, and the power source assembly 140 drives the first stirring assembly 120 and the second stirring assembly 130 to rotate to clean the surface to be cleaned. During the rotation of the first stirring assembly 120 and the second stirring assembly 130, impurities (including hair and dust, etc.) can be attached to the first stirring assembly 120 and the second stirring assembly 130. The air flowing from the suction chamber 111 to the air outlet passage 112 can carry the impurities away from the first stirring assembly 120 and the second stirring assembly 130, thereby achieving the cleaning function of the dust collecting head 100.

[0043] At the same time, since the flow guide 150 is arranged on the housing 110 and located between the fixed portion 113 and the air inlet 1121 of the air outlet passage 112, the flow guide 150 can shield the fixed portion 113 in the direction of the fixed portion 113 towards the air inlet 1121, preventing impurities from accumulating on the fixed portion 113 and being unable to be collected. At the same time, since at least part of the flow guide 150 is arranged at the gap between the first stirring assembly 120 and the second stirring assembly 130, the flow guide assembly can shield the gap between the first stirring assembly 120 and the second stirring assembly 130, preventing impurities from entering the inside of the first stirring assembly 120 and the second stirring assembly 130 through the gap, thereby reducing the risk of damage to the first stirring assembly 120 and the second stirring assembly 130, and improving the service life of the dust collecting head 100.

[0044] Optionally, the flow guide 150 can be arranged at the gap between the first stirring assembly 120 and the second stirring assembly 130, or a part of the flow guide 150 can be arranged at the gap between the first stirring assembly 120 and the second stirring assembly 130.

[0046] The flow guide 150 is arranged between the fixed part 113 and the air inlet 1121 of the air outlet channel 112, which is beneficial to improve the air flow effect in the suction chamber 111, i.e., beneficial to improve the air suction pressure at the position where the suction chamber 111 and the air outlet channel 112 are communicated, thereby improving the effect of the air carrying away the sundries. By arranging at least part of the flow guide 150 at the gap between the first stirring assembly 120 and the second stirring assembly 130, the flow guide 150 can shield the gap between the fixed part 113 and the first stirring assembly 120 and the second stirring assembly 130, prevent the sundries from accumulating on the fixed part 113 and being collected, and reduce the risk of the sundries blocking the air inlet 1121, and prevent the sundries from entering the first stirring assembly 120 and the second stirring assembly 130, thereby reducing the risk of damage to the first stirring assembly 120 and the second stirring assembly 130, and prolonging the service life of the dust collection head 100.

[0047] The power source assembly 140 can be configured as a motor.

[0049] That is, the radial dimension of the first stirring assembly 120 gradually decreases from the direction extending away from the fixed portion 113, the first stirring assembly 120 can stir the hair and other sundries in a spiral shape and can play a role of guiding the sundries in the direction of the first free end 121, when the air in the suction chamber 111 flows from the suction chamber 111 to the air outlet passage 112 side, the sundries can be sucked into the air outlet passage 112 from the first free end 121, which is conducive to reducing the risk of accumulation of sundries at the fixed portion 113, by designing the first stirring assembly 120 as a conical drum, which is conducive to improving the adaptability of the first stirring assembly 120 to different cleaning surfaces and ensuring the cleaning effect of the first stirring assembly 120.

[0050] In combination Figure 1 and Figure 4 , the second stirring assembly 130 includes a second free end 131 and a second fixed end 132, the second fixed end 132 is arranged near the fixed portion 113, and the radial dimension of the second stirring assembly 130 gradually decreases from the second fixed end 132 to the second free end 131, and the second stirring assembly 130 is configured as a conical drum.

[0051] That is, the radial dimension of the second stirring assembly 130 gradually decreases from the direction extending away from the fixed portion 113, the second stirring assembly 130 can stir the hair and other sundries in a spiral shape and can play a role of guiding the sundries in the direction of the second free end 131, when the air in the suction chamber 111 flows from the suction chamber 111 to the air outlet passage 112 side, the sundries can be sucked into the air outlet passage 112 from the first free end 121, which is conducive to reducing the risk of accumulation of sundries at the fixed portion 113, by designing the second stirring assembly 130 as a conical drum, which is conducive to improving the adaptability of the second stirring assembly 130 to different cleaning surfaces and ensuring the cleaning effect of the second stirring assembly 130.

[0052] In combination Figure 1 and Figure 3 In some embodiments of the utility model, the first axis and the second axis intersect, and the included angle between the first axis and the second axis opens downward and is set as an obtuse angle.

[0053] The first axis is the rotation axis of the first stirring assembly 120, and the second axis is the rotation axis of the second stirring assembly 130, considering that the lower surfaces of the first stirring assembly 120 and the second stirring assembly 130 need to be in contact with the cleaning surface respectively, by making the included angle between the first axis and the second axis open downward, it is convenient for the arrangement of the first stirring assembly 120 and the second stirring assembly 130, and it is convenient for the first stirring assembly 120 and the second stirring assembly 130 to be in contact with the cleaning surface.

[0054] Further, by setting the included angle between the first axis and the second axis as an obtuse angle, the contact area of the first stirring assembly 120 and the second stirring assembly 130 with the surface to be cleaned is increased, so that the cleaning effect and the cleaning efficiency of the first stirring assembly 120 and the second stirring assembly 130 on the surface to be cleaned are improved.

[0055] In some embodiments of the present application, the lower edge of the first stirring assembly 120 is arranged in line with the lower edge of the second stirring assembly 130 in the cross section of the plane in which the first axis and the second axis are located.

[0056] In the projection plane of the dust collection head 100 in the height direction (which can also be understood as the up-down direction or the vertical direction), the orthographic projection of the bottom wall of the suction chamber 111 falls within the orthographic projection range of the top wall 1111 of the suction chamber 111, that is, the area of the bottom wall of the suction chamber 111 is smaller than the area of the top wall 1111 of the suction chamber 111, so that the lower part of the suction chamber 111 is open and exposes the lower part of the first stirring assembly 120 and the lower part of the second stirring assembly 130, so that the lower edge of the first stirring assembly 120 and the lower edge of the second stirring assembly 130 can be in contact with the surface to be cleaned. By arranging the lower edge of the first stirring assembly 120 in line with the lower edge of the second stirring assembly 130, it is beneficial to ensure that the lower edge of the first stirring assembly 120 and the lower edge of the second stirring assembly 130 clean the surface to be cleaned at the same time, and it is beneficial to improve the cleaning effect and the cleaning efficiency of the dust collection head 100.

[0057] Further, the lower edges of the first stirring assembly 120 and the second stirring assembly 130 can be abutment matched, which is beneficial to reduce the risk of foreign matter entering the interior of the first stirring assembly and the second stirring assembly 130.

[0058] Referring to Figure 4 In some embodiments of the present application, the flow guide 150 has a first flow guide wall 151 and a second flow guide wall 152, the first flow guide wall 151 extends in an arc shape from the side adjacent to the first stirring assembly 120 to the direction towards the air inlet 1121, and the second flow guide wall 152 extends in an arc shape from the side adjacent to the second stirring assembly 130 to the direction towards the air inlet 1121.

[0059] Specifically, the flow guide piece 150 is formed with a first flow guide wall 151 and a second flow guide wall 152 on both sides in the length direction of the dust collection head 100, the first flow guide wall 151 extends from the side close to the first stirring assembly 120 to the direction of the air inlet 1121, and the first flow guide wall 151 is arc-shaped concave to the side wall of the suction chamber 111 opposite to the first flow guide wall 151, and the second flow guide wall 152 extends from the side close to the first stirring assembly 120 to the direction of the air inlet 1121, and the second flow guide wall 152 is arc-shaped concave to the side wall of the suction chamber 111 opposite to the second flow guide wall 152.

[0060] By extending the first flow guide wall 151 and the second flow guide wall 152 in an arc shape, the guiding effect of the first flow guide wall 151 and the second flow guide wall 152 on air is improved, that is, the guiding effect of the flow guide piece 150 on air flow is improved, and the resistance of air flowing through the first flow guide wall 151 and the second flow guide wall 152 is reduced, thereby facilitating the improvement of the air suction pressure on one side of the air outlet passage 112, the effect of air suction into the suction chamber 111 and the debris attached to the first stirring assembly 120 and the second stirring assembly 130, thereby facilitating the improvement of the cleaning effect of the dust collection head 100.

[0061] In combination with Figure 1 , Figure 3 and Figure 4 , in some embodiments of the utility model, the cross-sectional area of the suction chamber 111 gradually increases from the first free end 121 and the second free end 131 to the direction close to the fixed part 113, and the two side walls of the suction chamber 111 gradually extend from the side close to the first free end 121 and the second free end 131 to the direction close to the air inlet 1121, so that the two side walls of the suction chamber 111 can play a role in guiding air, which is conducive to improving the effect of air flowing to the air inlet 1121, thereby facilitating the effect of debris being sucked into the air inlet 1121 after being separated from the first free end 121 and the second free end 131.

[0062] Referring to Figure 4 , in some embodiments of the utility model, the first flow guide wall 151 and the wall of the suction chamber 111 define a first flow guide passage 101, and the flow passage cross-sectional area of the first flow guide passage 101 gradually decreases to the side of the air inlet 1121 of the air outlet passage 112.

[0063] That is, in the direction of the first stirring assembly 120 extending close to the air inlet 1121, the distance between the first flow guide wall 151 and the side wall of the suction chamber 111 opposite to the first flow guide wall 151 gradually decreases, so that the flow passage cross-sectional area of the first flow guide passage 101 gradually decreases, so as to improve the air suction pressure at the air inlet 1121, thereby facilitating the efficiency of air bringing debris into the dust collection device, and further facilitating the cleaning efficiency of the dust collection head 100.

[0064] The second flow guide wall 152 and the wall surface of the suction chamber 111 define a second flow guide passage 102, and the flow passage cross-sectional area of the second flow guide passage 102 gradually decreases towards the air inlet 1121 of the air outlet passage 112.

[0065] In the direction of extending the second stirring assembly 130 towards the air inlet 1121, the distance between the second flow guide wall 152 and the side wall surface of the suction chamber 111 opposite to the second flow guide wall 152 gradually decreases, so that the flow passage cross-sectional area of the second flow guide passage 102 gradually decreases, so as to increase the air suction pressure at the air inlet 1121, thereby facilitating the efficiency of air carrying the sundries into the dust collecting device.

[0066] In combination Figure 2 with Figure 3 In some embodiments of the present application, the flow guide 150 is arranged on the top wall 1111 of the suction chamber 111 and extends downward in the vertical direction, and at least part of the flow guide 150 is arranged opposite to the air inlet 1121 of the air outlet passage 112 in the air inlet direction.

[0068] As Figure 2 shown, in some embodiments of the present application, the bottom end of the flow guide 150 is spaced apart from the bottom wall of the suction chamber 111 in the vertical direction, which is conducive to preventing the flow guide 150 from blocking the air flow at the air inlet 1121 due to the excessive area of the air inlet 1121, ensuring the efficiency of the air flow at the air inlet 1121, and at the same time, it is conducive to reducing the material cost of the flow guide 150, and further conducive to reducing the production and processing cost of the dust collecting head 100.
