DETAILED DESCRIPTION

[0028] In order to make the purpose, technical scheme and advantages of the present application more clear, the present application will be further described in detail below with reference to the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and do not limit the present application.

[0029] Please refer to the attached Figures 1-8As shown, the utility model embodiment provides an operation knob 11, including knob main part, one side of knob main part is equipped with recess, the middle part of recess is equipped with partition beam 111, partition beam 111 divides recess into left recess 112 and right recess 113, partition beam 111 is equipped with step portion 116 on the side wall corresponding left recess 112 and right recess 113 respectively, step portion 116 is set to the bottom of recess. When operating, the fingers of a person respectively extend into left recess 112 and right recess 113 and thereby hold partition beam 111, the existing partition beam 111 is not provided with step portion 116 structure, because the volume of partition beam 111 is small, therefore when rotating and pulling (especially when pulling partition beam 111 outward), the fingers of a person and partition beam 111 are easy to slip, cause the trouble of disassembly, therefore the partition beam 111 of this embodiment is provided with step portion 116, the fingers of a person can be hooked on step portion 116 and operate, thereby avoiding the above-mentioned slip situation, therefore the operation of catching is easier. The operation knob 11 is applied to the roll brush assembly 10 and is easier to disassemble the roll brush.

[0030] The partition beam 111 includes an outer beam portion 114 and an inner beam portion 115, the inner beam portion 115 is connected to the knob main body on the inner side, the outer beam portion 114 is detachably connected to the inner beam portion 115 on the outer side, and the step portion 116 is formed in the staggered area on one side of the interface between the outer beam portion 114 and the inner beam portion 115. Since the step portion 116 is inwardly arranged, the operation knob 11 cannot be integrally casted (cannot be ground) during injection molding, so the partition beam 111 is manufactured by separately injection molding the outer beam portion 114 and the inner beam portion 115. In a preferred embodiment, the inner beam portion 115 and the knob main body are designed in an integrated structure, i.e., the inner beam portion 115 and the knob main body can be formed by one-time molding injection.

[0031] The outer beam portion 114 is provided with a mounting column 117, the inner beam portion 115 is provided with a mounting hole 119, and the mounting hole 119 penetrates to the back side of the knob main body, the mounting column 117 is embedded in the mounting hole 119, further comprising a fixing screw 15, the fixing screw 15 is screwed with the mounting column 117 from the back side of the knob main body through the mounting hole 119. During installation, the mounting column 117 is embedded in the mounting hole 119 to realize the installation and alignment of the outer beam portion 114 and the inner beam portion 115, and then the fixing screw 15 is tightened to form an integral body, which has the advantages of simple structure and convenient installation.

[0032] It should be noted that the abutting surface of the outer beam portion 114 is designed to be wider than that of the inner beam portion 115, and after abutting, the area on both sides of the outer beam portion 114 that exceeds the inner beam portion 115 forms the above-mentioned step portion 116.

[0033] The outer beam part 114 is further provided with positioning columns 118, and the inner beam part 115 is provided with positioning holes 120, the positioning columns 118 and the mounting columns 117 are arranged along the longitudinal direction of the outer beam part 114, and the positioning holes 120 and the mounting holes 119 are respectively arranged corresponding to the positioning columns 118 and the mounting columns 117.

[0034] Arc-shaped recesses 121 are arranged on both sides of the partition beam 111 and recessed from both ends to the middle part, when the partition beam 111 comprises the outer beam part 114 and the inner beam part 115, the arc-shaped recesses 121 are arranged at least on the outer beam part 114. By arranging the arc-shaped recesses 121, when a person grabs the partition beam 111, the fingers will naturally slide to the middle part of the partition beam 111, and it is more labor-saving to grab the middle part to rotate the knob 11.

[0035] The embodiment of the utility model further proposes a kind of rolling brush assembly 10, including cleaning roller 13, handle piece 12 being arranged at one end of cleaning roller 13 and operating knob 11 being arranged at the end of handle piece 12, the operating knob 11 is arranged as any described above operating knob 11, and the operating knob 11 is used for locking and unlocking operation when rolling brush assembly 10 is installed and disassembled.Further, it further includes fixing piece 14, the locking portion 141 and the limiting portion 142 are arranged on the fixing piece 14, the fixing piece 14 is arranged at the end of the handle piece 12 and is connected with the operating knob 11, and rotating the operating knob 11 can drive the fixing piece 14 to rotate.The rolling brush assembly 10 of the utility model applies the above-mentioned operating knob 11, uses step portion 116 when disassembling to provide a grabbing position for finger when rotating and pulling operating knob 11, so that it is easier when rolling brush assembly 10 is disassembled.

[0036] The embodiment of the utility model further proposes a kind of cleaning equipment, including equipment body 20 and with the detachable connection of rolling brush assembly 10 of equipment body 20, the rolling brush assembly 10 is arranged as the rolling brush assembly 10 described above.Further, the rolling brush assembly 10 is arranged as the rolling brush assembly 10 further including fixing piece 14 described above, and the first limiting groove 21 and the second limiting groove 22 are arranged on the equipment body 20, the first limiting groove 21 and the second limiting groove 22 are arranged at the angle interval of setting, when locking, the limiting portion 142 is at least partially embedded in the first limiting groove 21, when unlocking, the limiting portion 142 is at least partially embedded in the second limiting groove 22.By arranging the first limiting groove 21 and the second limiting groove 22, no matter rotating to unlocking position or locking position of operating knob 11, can be limited and fixed and not automatically rotated, so as to avoid the problem that operating knob 11 is automatically returned to locking position from unlocking position when disassembling rolling brush assembly 10.

[0037] In summary, the operation knob 11, the step part 116 towards the bottom of the recess part is arranged on the side wall of the partition beam 111, the step part 116 provides a position for fingers to grab when rotating and pulling the operation knob 11, so that the brush roll assembly 10 is more easily disassembled.
