However, one skilled in the art will readily recognize that some of the features may be omitted, or replaced by other elements, materials, or methods in different situations. In some instances, related operations of the present application have not been shown or described in the specification in order to avoid obscuring the core portions of the present application, and may be unnecessary to persons skilled in the art from a detailed description of the related operations, which may be presented in the description and general knowledge of one skilled in the art.

Furthermore, the features, operations, or characteristics described in the specification may be combined in any suitable manner to form various embodiments, and the operational steps involved in the embodiments may be sequentially exchanged or adjusted in a manner apparent to those skilled in the art. Accordingly, the description and drawings are merely for clarity of describing certain embodiments and are not necessarily intended to imply a required composition and/or order.

The numbering of the components itself, e.g. "first", "second", etc., is used herein merely to distinguish between the described objects and does not have any sequential or technical meaning. The term "coupled" as used herein includes both direct and indirect coupling (coupling), unless otherwise indicated.

The following are some examples of cleaning brushes, brush head attachments, and brush heads provided by the present application.

Referring to fig. 1 and 2, a cleaning brush 100 is provided in an embodiment of the application. The cleaning brush 100 comprises a brush head attachment 1, a brush head 2 and a handle assembly 3. The brush head 2 is of a soft structure to adapt to different appearance structures of objects to be cleaned, not only can clean objects with conventional shapes, but also can clean objects with grids, curved surfaces and the like (such as barbecue grills, barbecue ovens and the like), the brush head 2 is provided with a cleaning surface 21 serving as a working surface for cleaning operation, the brush head 2 is detachably connected with the brush head connecting piece 1, and the brush head connecting piece 1 is detachably connected with the handle assembly 3, so that assembly and fixation among the three are realized. When the user uses the cleaning brush 100 to perform a cleaning operation, the user can hold the handle assembly 3 and drive the brush head 2 to move on the surface of the object to be cleaned to perform the cleaning operation. The brush head 2 can be made of sponge, braiding material and the like.

It will be appreciated that when the brush is used to clean a barbecue grill, barbecue grill or the like, the brush head is often prone to wear due to high temperatures, oil stains and the like, requiring timely replacement. In the existing cleaning brush products, the brush head and the connecting piece are usually processed into an integral structure, so that the brush head and the connecting piece are difficult to be detached and replaced independently, and the brush head and the connecting piece are required to be replaced together once the brush head is worn.

In this embodiment, the brush head 2 and the brush head connector 1 are detachably connected, so that the brush head 2 can be replaced independently after the brush head 2 is worn, and the brush head connector 1 is not required to be replaced together, thereby reducing material waste, reducing use cost of a user, and conforming to the concept of energy conservation and environmental protection. And because the brush head connecting piece 1 and the handle component 3 are detachably connected, when the brush head connecting piece 1 is damaged, a user can independently replace the brush head connecting piece 1 according to the actual situation of the brush head connecting piece 1.

In a further embodiment of the present application, referring to fig. 1, 3 and 4, the brush head attachment 1 of the cleaning brush 100 specifically includes a fixing plate 11. The fixing plate 11 is located between the handle assembly 3 and the brush head, the fixing plate 11 has two opposite faces, one face of which is detachably connected with the brush head, and the face of the fixing plate 11 away from the brush head 2 is detachably connected with the handle assembly 3. Wherein, the surface of the brush head 2 far away from the fixed plate 11 forms a cleaning surface 21, and the cleaning surface 21 is used for contacting with the surface of the cleaned object to perform cleaning operation.

Through adopting fixed plate 11 to connect brush head 2 and handle subassembly 3, can increase the area of contact between brush head connecting piece 1 and the brush head 2 on the one hand, make the connection of brush head 2 more firm, on the other hand can also utilize the characteristics that fixed plate 11 thickness size is less relatively, reduce the space occupation in the thickness direction, be favorable to reducing the volume and the weight of cleaning brush 100.

In a further embodiment of the present application, referring to fig. 4, 5, 6 and 7, the fixing plate 11 and the brush head 2 are detachably connected by hooking the connection hook 111 and the felt structure 22 to each other. Specifically, a surface of the fixing plate 11 far from the handle assembly 3 (i.e. a surface facing the brush head 2) is provided with a connecting hook surface 111, the connecting hook surface 111 specifically comprises a plurality of hook structures 112, as illustrated in fig. 6 and 7, the plurality of hook structures 112 are distributed on the surface of the fixing plate 11 to form the connecting hook surface 111, a surface of the brush head 2 facing the fixing plate 11 is provided with a felt surface structure 22, and the felt surface structure 22 can form hooking connection with the hook structures 112 on the connecting hook surface 111 to realize connection and fixation between the brush head 2 and the fixing plate 11. When the brush head 2 needs to be replaced, the brush head 2 is separated from the fixed plate 11 by pulling the whole brush head 2 away from the fixed plate 11, and the disassembly of the brush head 2 is completed. Through adopting above-mentioned connected mode, can realize the quick dismantlement operation between brush head 2 and the fixed plate 11, and easy operation is convenient, need not with the help of professional instrument, and the user can accomplish by oneself.

Of course, the above is only one of the preferred connection modes of the brush head 2 in the cleaning brush 100 of the present application, and other connection modes of the brush head 2 can be adopted. For example, in another embodiment, a groove may be disposed on a surface of the fixing plate 11 facing the brush head 2, and corresponding connection structures (such as a hook structure 112 or other connection members) are disposed on an inner sidewall and/or a bottom wall of the groove, and when assembled, a part of the structure of the brush head 2 extends into the groove of the fixing plate 11 and forms a connection with the connection structure in the groove, so that the connection and fixation between the brush head 2 and the fixing plate 11 can be achieved.

In a further embodiment of the present application, referring to fig. 5 and 6, the brush head connector 1 is connected to the handle assembly 3 by a snap fit.
