[0038] Figure 3 FIG. 1 is a partial structure schematic view of a limiting structure according to some embodiments of the present application. Figure 4 FIG. 2 is another partial structure schematic view of a limiting structure according to some embodiments of the present application.
[0039] In some embodiments, a limiting structure is provided between the connecting block 2 and the brush handle 3.
[0040] The limiting structure can be used to limit the angle between the connecting block 2 and the brush handle 3, so as to limit the angle between the brush head 1 and the brush handle 3.
[0041] In some embodiments, the limiting structure can comprise various structures, for example, as shown in FIGS. 1 and 2, the limiting structure comprises a plurality of first limiting holes 51 provided on the brush handle 3, a second limiting hole 52 provided on the connecting block 2, and a limiting pin 53. Figure 3 Figure 4 In some embodiments, the first limiting holes 51 are provided around the rotation center of the connecting block 2. The second limiting hole 52 can be coaxial with any one of the first limiting holes 51. In some embodiments, the limiting pin 53 can pass through the first limiting hole 51 and the second limiting hole 52 to be connected. Thus, the angle between the connecting block 2 and the brush handle 3 is limited. In some embodiments, the first limiting holes 51 can be annularly and uniformly distributed. In some embodiments, at least part of the first limiting holes 51 can be communicated with each other.
[0042] In some embodiments, the limiting pin 53 can be connected with the connecting block 2 or the brush handle 3 in various ways, for example, by at least one of a connecting rope, a connecting belt, etc. Among them, the connecting rope and the connecting belt can be made of plastic or plastic.
[0043] In some embodiments, the outward end face of the limiting pin 53 is provided with a cross hole or a slot. In this way, the limiting pin 53 can be moved by a structure with a cross head or a slot head such as a screwdriver, thereby facilitating the installation or disassembly of the limiting pin 53.
[0044] In some embodiments, the limiting pin 53 is provided with a first limiting block 531. The first limiting block 531 is used to limit the relative position between the limiting pin 53 and the connecting block 2, and can prevent the limiting pin 53 from being separated from the connecting block 2 after the limiting pin 53 is connected with the connecting block 2.
[0045] In some embodiments, the inner hole face of the second limiting hole 52 is provided with a first limiting groove 521 and a second limiting groove (not shown in the figure) matched with the first limiting block 531. In some embodiments, the first limiting groove 521 is in communication with the second limiting groove.
[0046] In some embodiments, the length direction of the first limiting groove 521 is parallel to the axis of the second limiting hole 52, and the first limiting groove 521 can be used to guide the first limiting block 531 to move along the length direction of the first limiting groove 521 until the first limiting block 531 moves into the second limiting groove.
[0047] In some embodiments, the second limiting groove can be arranged along the circumference of the second limiting hole 52. After the first limiting block 531 moves into the second limiting groove, rotating the limiting pin 53 can make the first limiting block 531 move along the second limiting groove. In some embodiments, the central angle corresponding to the second limiting groove is less than 360°, for example, 180°, 90° or other values, and the specific value can be set according to actual needs. In this way, the first limiting block 531 can be prevented from being separated from the second limiting groove, and when the first limiting block 531 is located in the second limiting groove, the relative position between the limiting pin 53 and the connecting block 2 is locked.
[0048] In some embodiments, the inner hole face of the first limiting hole 51 is provided with a through groove through which the first limiting block 531 can pass.
[0049] In some embodiments, the limiting structure can include other structures. For example, the limiting structure can include a damping structure arranged between the connecting block 2 and the brush handle 3. By arranging the damping structure, when an external force is applied to the connecting block 2, the connecting block 2 and the brush handle 3 can rotate relative to each other, and when the external force is removed, the connecting block 2 and the brush handle 3 can remain relatively fixed.
[0050] In some embodiments, the outer surface of the connecting block 2 may be provided with anti-slip patterns, and the user can apply force to the anti-slip patterns to drive the connecting block 2 and the brush handle 3 to move relative to each other.
[0051] In some embodiments, the connecting block 2 and the brush head 1 can be detachably connected in various ways, as detailed below.
[0052] Figure 5 This is a schematic diagram of the connection between the connecting block and the brush head according to some embodiments of this application specification.
[0053] In some embodiments, such as Figure 5 As shown, the connecting block 2 has a mounting surface 21. The mounting surface 21 is parallel to the rotation center of the connecting block 2. In some embodiments, the mounting surface 21 can be a plane, which helps to improve the stability of the brush head 1 when the connecting block 2 is connected to the brush head 1. In some embodiments, the mounting surface 21 has a connecting hole 22. The brush head 1 has a connecting post 11 adapted to the connecting hole 22. In some embodiments, the side of the brush head 1 facing the mounting surface 21 can be parallel to and abut against the mounting surface 21.
[0054] In some embodiments, the axis of the connecting hole 22 may be perpendicular to the mounting surface 21.
[0055] In some embodiments, the connecting post 11 and the connecting hole 22 can be connected in a variety of ways.
[0056] In some embodiments, the connecting post 11 is provided with a second limiting block 111. The inner surface of the connecting hole 22 is provided with a third limiting groove 221 and a fourth limiting groove (not shown in the figure) that are adapted to the second limiting block 111.
[0057] In some embodiments, the length direction of the third limiting groove 221 is parallel to the axis of the connecting hole 22;
[0058] In some embodiments, the fourth limiting groove is disposed along the circumference of the connecting hole 22. In some embodiments, the third limiting groove 221 communicates with the fourth limiting groove.
[0059] The third limiting groove 221 can be used to guide the second limiting block 111 to move along the length direction of the third limiting groove 221 until the second limiting block 111 enters the fourth limiting groove. Rotating the brush head 1 can drive the second limiting block 111 to move along the fourth limiting groove. In some embodiments, the central angle corresponding to the fourth limiting groove is less than 360°, for example, 180°, 90° or other values, and the specific value can be set according to actual needs. This prevents the second limiting block 111 from disengaging from the fourth limiting groove. When the second limiting block 111 is located in the fourth limiting groove, the relative position of the brush head 1 and the connecting block 2 is locked.
[0060] In some embodiments, the connecting post 11 and the connecting hole 22 can be connected by other means. For example, expansion connection, etc.
[0061] In some embodiments, at least one elastic strip is arranged on the inner hole surface of the connecting hole 22. When the connecting post 11 is connected with the connecting hole 22, the elastic strip is extruded by the connecting post 11, so as to improve the connecting strength of the connecting post 11 and the connecting hole 22, and further prevent the connecting post 11 from loosening.
[0062] In some embodiments, the elastic strip can include various shapes. For example, at least one of straight line shape, ring shape, wave shape, spiral shape, etc. In some embodiments, the elastic strip can be formed by various means. For example, by using a mold to be integrally formed.
