[0026] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0027] "Brush head" generally refers to the part of a brush that is used to clean and comb surfaces or hair. The shape, material and design of the brush head vary depending on the specific purpose. The brush head is a multi-purpose cleaning tool. Choosing the right brush head can complete the cleaning and care work more effectively.

[0028] Embodiment 1:

[0029] Based on the technical defects of the existing technology, such as complicated installation and high production cost, please refer to Figure 1-Figure 5 The utility model provides a combined brush piece group. When the whole is assembled, it only needs to be pressed and snapped together. The installation is simple and convenient, and it can be suitable for installing brush pieces of different materials. The upper cover 1, the lower cover 2 and the snap-fit ​​component 4 can all be integrally formed by injection molding, without the need to use redundant connecting parts, thereby reducing the production cost. The combined brush piece group includes an upper cover 1 and a lower cover 2. A groove is provided on the inner side between the upper cover 1 and the lower cover 2. Two groups of snap-fit ​​components 4 for connecting the upper cover 1 and the lower cover 2 are provided in the groove. The snap-fit ​​component 4 is sleeved with an assembled brush piece 3 installed in the groove; when installing, a plurality of assembled brush pieces 3 are inserted into the snap-fit ​​component 4, and then the upper cover 1 and the lower cover 2 are closed, and the whole is connected under the action of the snap-fit ​​component 4.

[0030] To achieve quick connection between upper cover 1 and lower cover 2, please refer to Figure 2-Figure 4The snap-fit ​​assembly 4 includes a snap-fit ​​member 42 and a lock member 41. The snap-fit ​​member 42 is fixedly connected to the inner side of the groove of the upper cover 1, and the lock member 41 is fixedly connected to the inner side of the groove of the lower cover 2. The snap-fit ​​member 42 is inserted into the lock member 41. When the upper cover 1 and the lower cover 2 are closed, the snap-fit ​​member 42 can be smoothly inserted into the lock member 41. Due to the elastic deformation of the claw 412 in the lock member 41, the snap-fit ​​member 42 is locked, thereby realizing the overall assembly connection.

[0031] In order to make the snap-fit ​​assembly 1 4 be integrally formed with the upper cover 1 and the lower cover 2 by injection molding, please refer to Figure 3 and Figure 4 The latch 42 includes a locking column 421 fixedly connected to the inner side of the upper cover 1, a boss 422 with an isosceles trapezoidal cross section is fixedly provided at the bottom of the locking column 421, and the locking component 41 includes a hollow cylinder 411 fixedly connected to the inner side of the lower cover 2, two notches are provided on the side wall of the hollow cylinder 411, and claws 412 are integrally formed in the notches, and a hook locking portion 413 engaged with the boss 422 is provided on the top of the claw 412; the latch 42 is integrally formed with the upper cover 1, and the locking component 41 is integrally formed with the lower cover 2. When the upper cover 1 and the lower cover 2 are closed, the boss 422 on the latch 42 can be just inserted into the hollow cylinder 411 in the locking component 41, and then it can be locked under the action of the claw 412.

[0032] To ensure that the upper cover 1 and the lower cover 2 will not be skewed when they are closed, positioning columns 11 are provided at the four corners of the bottom of the upper cover 1. The bottom ends of the positioning columns 11 are tapered. The positioning columns 11 are inserted into positioning grooves 21 provided at the four corners of the top of the lower cover 2. The positioning columns 11 are inserted into the positioning grooves 21 to achieve positioning of the upper cover 1 and the lower cover 2 when they are closed.

[0033] To ensure that the brush can be stably installed between the upper cover 1 and the lower cover 2, please refer to Figure 5 The assembled brush piece 3 includes a flat head 31 and a brush strip portion 32 integrally formed on one side of the flat head 31, and a limiting hole 33 is provided on the flat head 31; by utilizing the limiting hole 33, the assembled brush piece 3 can be inserted into the snap-fit ​​component 4, so that after the upper cover 1 and the lower cover 2 are closed, multiple assembled brush pieces 3 can be fixed.

[0034] In order to increase the number of brush pieces, an integrated brush piece 7 is integrally formed on the side walls of the upper cover 1 and the lower cover 2 .

[0035] Embodiment 2:

[0036] The upper cover 1 and the lower cover 2 in the first embodiment cannot be disassembled after being combined, so the single assembled brush piece 3 cannot be replaced. The entire piece needs to be replaced when used later, which has the problem of high cost. Please refer to Figure 5-Figure 7On the basis of the first embodiment, two snap-fitting components 6 are fixed on both side walls of the lower cover 2, and the snap-fitting components 6 are snapped into the fixing grooves 12 provided on the two side walls of the upper cover 1; after the upper cover 1 and the lower cover 2 are connected by the snap-fitting components 6, the overall assembly can be realized.

[0037] In order to realize the disassembly of the upper cover 1 and the lower cover 2, the snap-fit ​​component 2 6 includes a fixing frame 61 fixedly connected to the side wall of the lower cover 2, the fixing frame 61 is rotatably connected to a lock buckle 63 through a rotating shaft 62, the top of the lock buckle 63 is snapped into the fixing groove 12, and a torsion spring 64 is sleeved on the outer wall of the rotating shaft 62; since the snap-fit ​​component 2 6 is located on the outside of the lower cover 2, the upper cover 1 and the lower cover 2 can be separated by pulling the lock buckle 63 outward, and then the assembled brush piece 3 can be replaced separately, saving the use cost.

[0038] To facilitate the fixation of the assembled brush piece 3 , two symmetrically arranged limiting posts 5 are fixed in the groove of the lower cover 2 ; the limiting holes 33 on the assembled brush piece 3 can be inserted into the limiting posts 5 to fix the assembled brush piece 3 .

[0039] It can be known from the above embodiments that during installation, multiple assembled brush pieces 3 are inserted into the snap-fit ​​component 1 4 or the limiting column 5, and then the upper cover 1 and the lower cover 2 are closed, and the whole is connected under the action of the snap-fit ​​component 1 4. At this time, the whole cannot be disassembled, but the installation is simple and fast, and the production cost is low. The whole is connected under the action of the snap-fit ​​component 2 6. Later, the upper cover 1 and the lower cover 2 can be separated by pushing the lock buckle 63 outward, and then the assembled brush piece 3 can be replaced separately, saving the use cost.

[0040] It should be noted that the terms "comprises", "includes" or any other variations thereof are intended to cover non-exclusive inclusion, so that a process, method, article or apparatus that includes a series of elements includes not only those elements, but also other elements not explicitly listed, or also includes elements inherent to such process, method, article or apparatus.

[0041] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
