Description

Technical Field

[0001] The utility model relates to an electric cleaning brush, in particular to an electric cleaning brush with an easy-to-replace brush head. Background Art

[0002] When people use traditional cleaning brushes to clean the bathroom or kitchen, they need to keep flushing with force, squat and keep moving when cleaning the edges and gaps, and also hold the detergent in one hand while pouring and brushing, which is very time-consuming and laborious. The emergence of electric cleaning brushes uses electricity instead of manual labor, which is more labor-saving and convenient to use.

[0003] The electric cleaning brush includes a brush head and a rod body. After being used for a long time, the brush head needs to be replaced. However, it is currently difficult to remove the brush head from the rod body, resulting in each replacement being time-consuming and laborious. Utility Model Content

[0004] In view of the deficiencies in the prior art, the utility model aims to provide an electric cleaning brush with an easy-to-replace brush head.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solution: it includes a brush head and a rod body, a protrusion is arranged at the end of the rod body, an annular groove is arranged at the outer periphery of the protrusion and the inner wall of the annular groove is arranged in an arc direction, a matching groove is arranged on the side of the brush head relatively close to the rod body, a plurality of spring sheets are arranged in the matching groove, and there is an accommodating space for accommodating the protrusion between the plurality of spring sheets, a guide inclined surface is arranged on the other side of the spring sheet relative to the matching groove and the guide inclined surface is opposite to the protrusion, a protruding block engaged with the annular groove is arranged on the spring sheet and the protruding block is located at the end of the guide inclined surface.

[0006] By adopting the above technical solution, when the brush head needs to be installed, the matching groove of the brush head is aligned with the protrusion of the rod body so that the protrusion enters the accommodating space. At this time, the guiding inclined surface is against the protrusion. As the protrusion continues to enter, the spring piece deforms outward until the annular groove of the protrusion is aligned with the protruding block. At this time, the protruding block enters the annular groove. Under the action of the spring piece, the fixation of the brush head and the rod body is completed. When disassembly is required, since the annular groove is in an arc shape, the protruding block is easily moved out of the annular groove, and the brush head mainly rotates, that is, it is mainly subjected to annular force, and the axial force is relatively small, and it will not fall off during work.

[0007] The utility model is further configured as follows: the protrusion is in a triangular prism shape and has ribs, a plurality of matching arc surfaces are circumferentially arranged in the matching groove and the matching arc surfaces are arranged continuously, the spring sheets are arranged in the matching arc surfaces at intervals, and the ribs are located between the spring sheets.

[0008] By adopting the above technical solution, the number of matching arc surfaces is six, the springs are arranged on three of them and are arranged at intervals, and the edges are opposite to the remaining three matching arc surfaces, ensuring the synchronous rotation of the protrusion and the brush head.

[0009] The utility model is further configured as follows: a matching block is arranged on the brush head, the matching groove is arranged in the matching block, and a fixing groove opposite to the matching block is arranged on the periphery of the protruding block.

[0010] The utility model is further configured as follows: the rod body comprises a control portion and a rod portion, the convex block is arranged at one end of the control portion, and the other end is detachably fixed to the rod portion.

[0011] The utility model is further configured as follows: a limiting block is arranged on the outer periphery of one end of the rod portion relatively close to the control portion, and a receiving groove adapted to the rod portion is arranged at the other end of the control portion relatively close to the protrusion, a sliding channel for the limiting block to slide is arranged in the receiving groove, and an annular limiting groove is arranged at the end of the sliding channel.

[0012] By adopting the above technical solution, when the rod part and the control part are fixed, the limit block is aligned with the sliding channel and slid in until the limit block moves to the end of the sliding channel and enters the annular limit groove. Then the rod part is rotated to make the limit block and the sliding channel misaligned. At this time, the rod part and the control part cannot be separated.

[0013] The utility model is further configured as follows: a charging port is provided in the receiving groove. By adopting the above technical solution, the charging port will be blocked by the rod when in use, effectively preventing water from entering. BRIEF DESCRIPTION OF THE DRAWINGS
