Detailed Description

It should be noted that, in the present application, technical features in examples and embodiments may be combined with each other without conflict, and the detailed description in the specific embodiment should be understood as an explanation of the gist of the present application and should not be construed as an improper limitation to the present application.

Referring to fig. 1 to 3, the cleaning brush head includes a housing 10, a rolling brush 20, and a hair cutting assembly 30. The roll brush 20 is rotatably provided on the housing 10; the hair cutting assembly 30 cuts the hairs on the drum brush 20 by moving on the housing 10 in the axial direction of the drum brush 20 in the non-operation state of the drum brush 20.

Another embodiment of the present application provides a cleaning appliance comprising a cleaning head as provided in any of the embodiments of the present application.

Specifically, the cleaning electric appliance described in the embodiment of the present application refers to any one of a dust collector, a mite removing instrument, a floor washing robot, and the like, which has a cleaning brush head.

The non-operation state of the roller brush 20 means that the roller brush 20 is substantially kept in a stationary state at this time, that is, the cleaning brush head of the embodiment of the present application cuts hairs wound around the roller brush 20 in a state in which the roller brush 20 is relatively stationary, compared to the manner in which the hairs are cut off by the blade during the high-speed rotation of the roller brush as used in the related art.

The hair cutting assembly 30 cuts the hairs on the drum brush 20 by moving on the housing 10 in the axial direction of the drum brush 20 means that the hair cutting assembly 30 moves not only on the housing 10 but also in the axial direction of the drum brush 20 in cutting the hairs on the drum brush 20, and it is understood that the movement in the axial direction of the drum brush 20 as described herein means that the hair cutting assembly 30 can move substantially from one end in the axial direction of the drum brush 20 to the other end in the axial direction of the drum brush 20, and does not mean that the moving direction of the hair cutting assembly 30 must be parallel to the axis of the drum brush 20.

The cleaning brush head of the embodiment of the application is provided with the hair cutting assembly 30, the hair cutting assembly 30 can cut off the hair wound on the rolling brush 20 through axial movement of the rolling brush 20 on the shell 10 under the non-working state, the cutting mode has no requirement on the length of the hair, no requirement on the tightness of the hair wound on the rolling brush 20 is met, the hair cleaning effect is good, and the efficiency is high.

In addition, after the hair cutting assembly 30 cuts off the hair on the rolling brush 20, the cleaning appliance can be started to suck the cut hair away, and the user does not need to touch the hair with hands to clean the hair, so that the user experience can be effectively improved.

It should be noted that the cleaning head shown in fig. 1 to 3 is used to move the hair-cutting assembly 30 manually, in some embodiments, the hair-cutting assembly 30 can also be moved electrically, for example, a driving assembly can be provided to drive the hair-cutting assembly 30 to move on the housing 10 along the axial direction of the rolling brush 20.

The hair cutting assembly 30 may have various structures, and for example, the hair cutting assembly 30 may be composed of a cutter housing 31 and a cutter 32 connected to the cutter housing 31, the cutter housing 31 is used for mounting the cutter 32, the cutter 32 is used for cutting hair, and the shape of the cutting edge of the cutter 32 is not limited.

The cutter 32 can be fixedly connected with the cutter shell 31, that is, when the hair cutting assembly 30 moves on the housing 10 along the axial direction of the rolling brush 20, the cutter 32 and the cutter shell 31 are kept relatively stationary, and the cutter 32 cuts the hair on the rolling brush 20 through translation; the cutter 32 may also be rotatably connected to the cutter housing 31. For example, referring to fig. 3, 6 and 7, the cutter housing 31 may be composed of a cutter holder 311 and a cutter cover 312, the cutter 32 is disposed on one side of the cutter holder 311 and rotatably connected to the cutter holder 311, the cutter cover 312 is disposed on one side of the cutter 32 facing away from the cutter holder 311, and the cutter 32 can cut hairs on the roller brush 20 by rolling on the roller brush 20 when the hair cutting assembly 30 moves on the housing 10 along the axial direction of the roller brush 20.

In one embodiment, referring to fig. 3, the rolling brush 20 includes a body 21, and an anvil 22 and a cleaning member 23 disposed on an outer surface of the body 21, the anvil 22 extends along an axial direction of the body 21, a cross-section of the anvil 22 is not limited, for example, a cross-section of the anvil 22 may be rectangular, V-shaped, trapezoidal, semicircular, etc., and the cutter 32 rolls on the anvil 22 when the hair cutting assembly 30 moves on the housing 10 along the axial direction of the rolling brush 20.

Specifically, the cleaning member 23 may be a cleaning brush bar, a cleaning bristle, or the like, and exemplarily, referring to fig. 3, the cleaning member 23 is a cleaning brush bar, and preferably, the setting height of the anvil 22 on the body 21 may be lower than or equal to the setting height of the cleaning brush bar on the body 21, so as to prevent the anvil 22 from forming an obstacle to the rolling of the roller brush 20 on the floor when the roller brush 20 rotates in the working state.

The material of the chopping board 22 and the body 21 may be the same or different, and preferably, the chopping board 22 and the body 21 are made of the same material, and the chopping board 22 and the body 21 can be integrally formed by injection molding. The anvil 22 may be positioned to facilitate cutting of hair at specific locations on the roller brush 20 to minimize the cutting blade 32 from cutting through the cleaning elements 23.

When the number of the cutting boards 22 is at least two, each cutting board 22 may be arranged at intervals along the circumference of the body 21, the cutting knife 32 may roll on only one cutting board 22, or may roll on different cutting boards 22 in sequence, for example, after the cutting knife 32 rolls on one cutting board 22, the other cutting board 22 may be aligned with the cutting knife 32 by rotating the rolling brush 20, and the cutting knife 32 continues to roll on the cutting board 22 aligned with the cutting knife 32, which is equivalent to that the cutting knife 32 can cut hairs at different positions of the rolling brush 20, thereby further improving the cutting effect of the hairs.

To facilitate the alignment of the anvil 22 and the cutting knife 32, for example, referring to fig. 1 to 3, a positioning knob may be disposed on the rolling brush 20, the positioning knob is disposed at an axial end of the body 21, and when the rolling brush 20 is in a non-working state, the positioning knob drives the body 21 to rotate under an external force, so that the anvil 22 moves to a cutting position aligned with the cutting knife 32. That is, the user can rotate the anvil 22 to a cutting position that can be aligned with the cutting blade 32 by rotating the positioning knob to ensure that the cutting blade 32 can roll on the anvil 22.

Further, please refer to fig. 3, the positioning knob may be provided with a positioning rib 24a capable of being exposed in an external view field, that is, the user may see the positioning rib 24a on the positioning knob, the positioning rib 24a corresponds to a setting position of the anvil plate 22, the number and shape of the positioning ribs 24a may also be adjusted according to the number of the anvil plate 22, and in the process of rotating the positioning knob, the user may determine whether the anvil plate 22 has moved to the cutting position by observing the position of the positioning rib 24a, thereby facilitating the user operation.

In some embodiments, a first positioning mark may be disposed on the positioning knob, and a second positioning mark may be disposed on an area of the housing 10 located on the peripheral side of the positioning knob, where when the anvil 22 moves to the cutting position, the first positioning mark and the second positioning mark are aligned, that is, the user may also determine whether the anvil 22 moves to the cutting position by whether the first positioning mark and the second positioning mark are aligned.

In some embodiments, the anvil 22 may not be provided, for example, the cutting blade 32 may roll directly on the body 21.
