[0018] The technical solutions in the embodiments of the application will be clearly and completely described below with reference to the drawings in the embodiments of the application. Obviously, the described embodiments are only part of the embodiments of the application, rather than all the embodiments of the application. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative work fall within the protection scope of the application.

[0019] As Figures 1-6The technical scheme is shown, and the utility model provides the following technical scheme: a dust collector brush head, including casing 20 and rolling brush 10, casing 20 is set outside rolling brush 10, casing 20 includes upper casing 21 and lower casing 22, upper casing 21 and lower casing 22 are detachably connected through connecting assembly 30, and upper casing 21 and lower casing 22 can rotate around the axial direction of rolling brush 10, upper casing 21 is connected with the dust collector main body, and lower casing 22 is in contact with the surface to be cleaned. Through the detachable lower casing 22, the overall cleaning of the brush head is realized, the lower casing 22 can be detached for water washing and other operations, and other electrical elements on the brush head are not affected, which is more safe and reliable. After the lower casing 22 is detached, the rolling brush 10 can be conveniently cleaned and replaced. In addition, since upper casing 21 and lower casing 22 can rotate around the axial direction of rolling brush 10, upper casing 21 is connected with the dust collector main body, and lower casing 22 is in contact with the surface to be cleaned, when the user holds the dust collector main body to clean, no matter how far the brush head is pushed, lower casing 22 can be attached to the surface to be cleaned, only upper casing 21 rotates, and the effectiveness of cleaning is ensured.

[0020] Specifically, as shown in the drawings, Figures 2-4 The connecting assembly 30 is rotatably arranged at one end of the lower casing 22, and a protrusion is arranged on the connecting assembly 30 and can be matched with the groove 211 arranged at the end of the upper casing 21. When the protrusion and the groove 211 are matched and clamped, the lower casing 22 is connected with the upper casing 21. If it is desired to detach the lower casing 22 from the upper casing 21, the connecting assembly 30 can be rotated away from the user end during use, so that the protrusion of the connecting assembly 30 is separated from the groove 211 of the upper casing 21, and then the lower casing 22 is pulled out to the right. As shown in the drawings, Figure 1 When the lower casing 22 is completely separated from the upper casing 21, the rolling brush 10 can be easily detached from the upper casing 21.

[0021] As shown in the drawings, Figure 6 The upper casing 21 is rotatably provided with a rolling brush shaft 213, the rolling brush shaft 213 is provided with a spiral thread for mounting the rolling brush 10, and the inner side of the rolling brush 10 is provided with a size-matched spiral groove, so that the rolling brush 10 can be conveniently detached.

[0022] As shown in the drawings, Figure 5As shown, the lower housing 22 comprises a cylinder 221 with an opening and a bottom plate 222 extending outward along the opening, the opening is used to expose the roller brush 10 so that the roller brush 10 can be in contact with the surface to be cleaned. The bottom plate 222 can increase the contact area between the lower housing 22 and the surface to be cleaned, when the cleaner brush head is used to clean sofa, curtains, carpets and other fabric products, the bottom plate 222 can first flatten the fabric product to facilitate subsequent dust suction. The bottom plate 222 is provided with a ventilation slot 223, when the cleaner uses a strong mode, the suction force is large, and the cleaner brush head is easy to suck the fabric product, the ventilation slot 223 is opened to make the gas circulate, thereby smoothly pushing the cleaner brush head on the fabric product.

[0023] As shown in Figure 5 and Figure 6 As shown, one end of the roller brush 10 is detachably connected with the upper housing 21, and the other end is suspended to facilitate the disassembly of the roller brush 10, and the suspended end avoids the entanglement of the hair at the connection of the roller brush, and reduces the occurrence of failure.

[0024] The upper housing 21 is provided with a suction port 212, and the lower housing 22 is provided with a through hole 224 at a corresponding position, when the upper housing 21 and the lower housing 22 are connected with each other, the suction port 212 and the through hole 224 at least partially overlap, and the suction port 212 and the through hole 224 are located at the suspended end of the roller brush 10. The suction port 212 located at the suspended end of the roller brush 10 can avoid the entanglement or jamming of large foreign matters with the roller brush 10 when the large foreign matters are sucked, without damaging the suction force of the cleaner, and the suction strength is larger.

[0025] Although the utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions recorded in the foregoing embodiments, or make equivalent replacement to part of the technical features, any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model should be included in the protection scope of the utility model.
