[0001] The present application relates to the technical field of dust suction devices, in particular to a dust suction device. BACKGROUND

[0002] There are many dust suction devices on the market at present, such as cylinder vacuum cleaners, upright vacuum cleaners, sweeping robots and the like. The existing dust suction devices often clean through the combination of a rolling brush, a walking wheel and a vacuum suction port. However, the rolling brush and the walking wheel on the bottom surface of the cleaning head are easily entangled by foreign matters such as hair on the ground. After long-term use, a large amount of sundries will also accumulate in the installation groove of the rolling brush. These sundries are blocked in the installation groove and cannot be sucked away by the suction port. Therefore, it is necessary to frequently disassemble the rolling brush for deep cleaning, which consumes manpower, has poor user experience, and greatly reduces the service life of the cleaning head.

[0003] It should be noted that the above content belongs to the technical cognition of the inventor and does not necessarily constitute the prior art. SUMMARY

[0004] The purpose of the present application is to provide a surface cleaning head of a dust suction device to solve the problems of unsatisfactory cleaning effect, frequent disassembly, inconvenience in use and short service life of the existing dust suction device.

[0005] To achieve the above purpose, the present application provides a surface cleaning head of a dust suction device, which comprises:

[0006] A housing defines an installation groove, a spiral guide rib is arranged in the installation groove, and a suction port is also arranged in the installation groove.

[0007] A brush roller is rotatably installed in the installation groove. The brush roller comprises a brush roller body and a cleaning component arranged on the surface of the brush roller body. The cleaning component can contact the spiral guide rib.

[0008] By arranging the spiral guide rib, the sundries can be guided to move in a certain direction. When the brush roller rotates, the cleaning component contacts the spiral guide rib. The two components cooperate to make the hair or paper ball sundries entangled on the cleaning component migrate and concentrate to a specified area along the spiral direction of the spiral guide rib under the action of the spiral force generated by rotation. Therefore, the sundries are more easily sucked into the suction port, avoiding the accumulation of sundries in the installation groove. The cleaning efficiency is high and the cleaning is thorough.

[0010] In the preferred implementation of the surface cleaning head of the vacuum cleaning device, the cleaning components extend along the axis of the brush roller body in a spiral manner, and the spiral direction of the spiral guide ribs is opposite to the spiral direction of the cleaning components. The spiral guide ribs can help the debris to be separated from the cleaning components on the brush roller and be sucked by the suction port, thereby improving the cleaning effect.

[0011] In the preferred implementation of the surface cleaning head of the vacuum cleaning device, the cleaning components include a plurality of cleaning strips and a plurality of bristle rows, each cleaning strip extends along the axis of the brush roller body, the plurality of cleaning strips are arranged at intervals along the circumference of the brush roller body, the bristle row is located on one side of the cleaning strip, the length of the bristle row is less than the length of the cleaning strip adjacent thereto, and the projection of the plurality of bristle rows on the axis of the brush roller body forms a continuous line segment. On the basis of comprehensive cleaning, the rotation resistance of the brush roller is small, the cleaning efficiency is high, and the hair entanglement can be effectively prevented.

[0012] In the preferred implementation of the surface cleaning head of the vacuum cleaning device, the height of the bristle row is greater than the height of the cleaning strip, which reduces the wear of the cleaning strip and prolongs the service life.

[0013] In the preferred implementation of the surface cleaning head of the vacuum cleaning device, the cleaning strip includes a forward cleaning strip extending along the axis of the brush roller body in a forward spiral manner and a reverse cleaning strip extending along the axis of the brush roller body in a reverse spiral manner; the spiral guide rib includes a forward spiral guide rib and a reverse spiral guide rib, the reverse cleaning strip is in contact with the forward spiral guide rib, and the forward cleaning strip is in contact with the reverse spiral guide rib.

[0014] In the preferred implementation of the surface cleaning head of the vacuum cleaning device, the suction port of the surface cleaning head corresponds to the middle section of the brush roller body, and the forward cleaning strip and the reverse cleaning strip are staggered in the middle section of the brush roller body. The effect of high debris collection efficiency is achieved.

[0030] In order to more clearly illustrate the overall concept of the present invention, a detailed description is given below in combination with the accompanying drawings by way of examples.

[0031] It should be noted that many specific details are set forth in the following description to facilitate a full understanding of the present invention. However, the present invention can also be implemented in other ways different from those described herein. Therefore, the scope of protection of the present invention is not limited to the specific embodiments disclosed below.

[0032] In the description of the present application, it needs to be understood that the terms "center", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "axial", "radial", "circumferential" and the like indicate the orientation or positional relationship based on the orientation or positional relationship shown in the drawings, only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a particular orientation, be constructed and operated in a particular orientation, and therefore cannot be understood as a limitation on the present application.

[0033] Figure 1 An exploded structural schematic diagram illustrating an embodiment of the surface cleaning head of the dust collection equipment is shown in FIG. 1. Figure 1 As shown in the figure, the surface cleaning head of the dust collection equipment includes a shell 10 and a brush roller 20. The shell 10 defines a mounting groove 11, in which a spiral guide rib 111 is arranged, and a dust suction port is also arranged in the mounting groove 11. The brush roller 20 is rotatably mounted in the mounting groove 11, as shown in the figure, both ends of the brush roller 20 are fixed at both ends of the mounting groove 11, and the brush roller 20 can rotate around its axis. Figure 1 The brush roller 20 includes a brush roller body 21 and a cleaning component 22 arranged on the surface of the brush roller body 21. As can be understood by those skilled in the art, the spiral guide rib 111 has a certain height in the mounting groove 11, and when the brush roller 20 is mounted in the mounting groove 11, the cleaning component 22 is in contact with the spiral guide rib 111 when the brush roller 20 rotates.

[0034] In the illustrated embodiment, the dust collection equipment is a robot vacuum cleaner, and according to needs, the dust collection equipment can also be other types of vacuum cleaners and the like.

[0035] When the robot vacuum cleaner is working, the brush roller 20 rotates to roll the dirt on the ground into the mounting groove 11, and then the dirt is sucked away by the dust suction port, completing the cleaning. Due to the arrangement of the spiral guide rib 111, it has a guiding effect on the dirt, and when the brush roller 20 rotates, the cleaning component 22 is in contact with the spiral guide rib 111, and the hair or paper ball type dirt wrapped around the cleaning component 22 migrates and concentrates in the designated area along the spiral direction of the spiral guide rib 111 under the action of the spiral force generated by the rotation, so the dirt more easily enters the dust suction port and is usually not accumulated in the mounting groove 11, thus the cleaning efficiency is high and the cleaning is thorough. People do not need to frequently disassemble the brush roller 20 for deep cleaning, which not only avoids damaging the brush roller 20 during disassembly and affecting its service life, but also saves the trouble of disassembling the brush roller 20, improving the user experience.

[0036] In the illustrated embodiment, the spiral guide rib 111 is located at both ends of the mounting groove 11. The spiral guide rib can also play a role in blocking the dirt from entering the end of the mounting groove 11, effectively avoiding the ends of the brush roller 20 being blocked by hair entanglement during rotation, and ensuring the normal rotation of the brush roller 20.

[0037] Figure 2 A schematic diagram of an exploded structure of another embodiment of a surface cleaning head for a vacuum cleaner. Figure 2 As shown, the cleaning member 22 extends spirally along the axial direction of the brush roller body 21, as indicated by the arrow in the figure, and the spiral direction of the spiral guide rib 111 is opposite to the spiral direction of the cleaning member 22. In this embodiment, when debris is caught by the brush roller 20, the spiral guide rib 111 can separate the debris from the cleaning member 21 on the brush roller, assisting the debris in migrating toward the suction port and being sucked away, thereby improving the cleaning effect. Of course, depending on design requirements, the spiral direction of the spiral guide rib 111 can be consistent with the rotation direction of the brush roller 20. The combination of the two can concentrate debris and migrate toward the suction port, which is beneficial to improving cleaning efficiency.

[0038] Figure 3 A schematic diagram illustrating an embodiment of a cleaning component. Figure 3 As shown, the cleaning component 22 includes a plurality of cleaning strips 221 and a plurality of bristle rows 222. Each cleaning strip 221 extends along the axial direction of the brush roller body. The plurality of cleaning strips 222 are arranged at intervals along the circumference of the brush roller body 21. The bristle rows 222 are located on one side of the cleaning strips 221. The length d1 of the bristle rows 222 is less than the length d2 of the adjacent cleaning strips 221. The projections of the plurality of bristle rows 222 on the axis of the brush roller body 21 form a continuous line segment, see Figure 3 , which is equivalent to when the brush roller body 21 rotates one circle in the direction of the arrow in the figure, multiple bristle rows 222 can clean the area corresponding to d3 in the ground 30. The length d1 of the bristle row 222 is less than the length d2 of the adjacent cleaning strip 221, which can reduce the resistance encountered by the brush roller body 21 when it rotates, and the cleaning efficiency is high. The projections of the multiple bristle rows 222 on the axis of the brush roller body 21 form a continuous line segment. The area that one bristle row 22 fails to clean can be cleaned by other bristle rows 222 after the brush roller body 21 rotates one circle, ensuring comprehensive cleaning. Therefore, this embodiment has extremely high cleaning efficiency on the basis of comprehensive cleaning. In addition, the cleaning strip 221 can be, but is not limited to, a brush felt, a brush sheet, or a brush cloth. The combination of the cleaning head 221 and the bristle row 222 can effectively prevent hair from being entangled at the root of the bristle row 222.

[0039] Figure 4 A side view of the structure of an embodiment of a cleaning component is provided. Figure 4 As shown, the height h2 of the bristle row 222 is greater than the height h1 of the cleaning strip 221. Height refers to the radial length of the brush roller body 21. This prevents hair from tangling around the roots of the bristle row 222, ensuring effective hair cleaning while effectively reducing wear on the cleaning strip 221 and extending its service life.

[0040] existFigure 3 In the embodiment shown, the cleaning strips 221 include forward cleaning strips 2211 extending in a forward helical manner along the axial direction of the brush roll body 21 and reverse cleaning strips 2212 extending in a reverse helical manner along the axial direction of the brush roll body 21. Please refer to Figure 1 , the helical guide ribs 111 include forward helical guide ribs 1111 and reverse helical guide ribs 1112, the reverse cleaning strips 2212 are in contact with the forward helical guide ribs 1111, and the forward cleaning strips 2211 are in contact with the reverse helical guide ribs 1112. In this way, it is more conducive to the separation of the debris from the cleaning strips 221.

[0041] In Figure 3 the embodiment shown, the suction port (not shown) of the surface cleaning head corresponds to the middle section A of the brush roll body 21, and the forward cleaning strips 2211 and the reverse cleaning strips 2212 are staggered at the middle section A of the brush roll body 21. It can be understood that the forward cleaning strips 2211 and the reverse cleaning strips 2212 are alternately distributed on the surface of the brush roll body 21, and the projection length of both on the axis of the brush roll body 21 is greater than half the length of the axis of the brush roll body 21. Therefore, the ends of the two cleaning strips opposite to each other in the opposite helical directions extend towards each other in the staggered area without contact in the form of crossing, etc. The debris that is rolled up can be concentrated in the staggered area of each cleaning strip, thereby improving the efficiency of debris collection, and the concentrated debris is close to the suction port, so that the debris is more easily sucked away by the larger suction force at the suction port, thereby assisting in the cleaning of the concentrated debris.

[0042] Figure 5 A structural schematic diagram illustrating an embodiment of the comb structure. As Figure 5 shown, the surface cleaning head further includes a comb structure 40. Please refer to Figure 1 , the comb structure 40 is disposed in the mounting groove 11 and faces the brush roll 20. The position of the comb structure 40 corresponds to the middle section of the brush roll body 21, that is, in the embodiment, the comb structure 40 is in the middle of the mounting groove 11. Figure 5 As shown, the comb structure 40 is an irregular structure including a comb body 41 and a plurality of comb strips 42 disposed on the comb body 41. The comb body 41 is fixed to the mounting groove 11, and the comb strips 42 extend towards the brush roll 20 and are inclined to one end of the brush roll body 21. The debris, especially the fine hair, concentrated on the staggered area of the cleaning strips is effectively cleaned, which is conducive to improving the effect of hair cleaning.

[0043] The technical solutions of the present application are not limited to the above-mentioned embodiments. It should be noted that the technical solutions of any one embodiment combined with the technical solutions of one or more other embodiments are within the scope of the present application. Although the present application has been described in detail above with general description and specific embodiments, some modifications or improvements can be made on the basis of the present application, which is obvious to those skilled in the art. Therefore, these modifications or improvements made on the basis of not deviating from the spirit of the present application are within the scope of the present application.
