Description

Technical Field

[0001] This utility model relates to the field of vacuum cleaner floor brush harness technology, and in particular to a floor brush harness connection device. Background Technology

[0002] Vacuum cleaner floor brushes typically include motorized soft brushes, motorized mite-removal brushes, and crevice tools. These brush heads are designed for different cleaning needs. For example, motorized soft brushes are suitable for hard floors, motorized mite-removal brushes are suitable for cleaning mites and dust from furniture such as sofas and beds, and crevice tools are suitable for cleaning hard-to-reach areas such as furniture crevices. The floor brushes are electrically driven, enabling them to efficiently complete various cleaning tasks. The power supply components of a vacuum cleaner floor brush mainly include a power interface, a motor, and the vacuum cleaner itself, with all electrical components connected by a wiring harness.

[0003] In the existing technology, the wiring harnesses used to connect the various electrical components of the vacuum cleaner floor brush are usually scattered inside the machine housing, which is not only unsightly, but also makes it difficult to repair the vacuum cleaner floor brush when it malfunctions. Utility Model Content

[0004] To solve the above problems, this utility model provides a floor brush harness connection device.

[0005] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a floor brush harness connection device, comprising a harness group electrically connected to the battery of a vacuum cleaner, the harness group comprising a central harness and branch harnesses, the central harness and branch harnesses being electrically connected to different electrical components inside the vacuum cleaner, the branch harnesses having a straight segment parallel to the central harness and a branch segment forming an angle with the central harness, and the branch segments of both the central harness and the branch harnesses being provided with a connecting mechanism for straightening and connecting the branch segments of the central harness or the branch harnesses to the inner wall of the vacuum cleaner housing.

[0006] By adopting the above technical solution and setting the connection mechanism, the branch sections of the intermediate wire harness or branch wire harness can be connected to the inner wall of the vacuum cleaner housing, ensuring the stability and neatness of the wire harness group inside the vacuum cleaner housing, improving the aesthetics of the wire harness group arrangement, and facilitating the maintenance of the power supply line inside the vacuum cleaner by the staff later.

[0007] Furthermore, the connection mechanism includes a connection component, which includes a first connection block and a second connection block hinged to the first connection block. The first connection block and the second connection block are each provided with a semi-circular groove on their respective sides that engages with the cables of the intermediate wire harness or the branch wire harness. The axis of the semi-circular groove is parallel to the cable axis of the intermediate wire harness or the cable axis of the branch wire harness. The connection mechanism also includes a fixing component disposed on the first connection block and used to fix the second connection block.

[0008] By adopting the above technical solution, the fixing component fixes the first connecting block and the second connecting block. The semi-circular grooves on the first connecting block or the second connecting block are engaged with the cables of the intermediate wire harness or the branch wire harness, which ensures the neatness of the cable arrangement of the cables of the intermediate wire harness or the branch wire harness and improves the aesthetics.

[0009] Furthermore, the fixing component includes a threaded rod fixed to the side wall of the first connecting block near the second connecting block, and a nut sleeved on the threaded rod and threadedly connected to the threaded rod. The threaded rod is located near the edge of the first connecting block, and the side wall of the second connecting block is provided with an installation port for installing the threaded rod. The nut is located on the side of the second connecting block away from the first connecting block.

[0010] By adopting the above technical solution, once the semi-circular grooves on the first or second connecting block are engaged with the cables of the intermediate wire harness or the branch wire harness, the operator only needs to tighten the nut to achieve the purpose of fixing the cables of the intermediate wire harness or the branch wire harness through the cooperation of the second connecting block and the first connecting block.

[0011] Furthermore, the fixing assembly also includes a rubber rod fixed to the side wall of the first connecting block away from the second connecting block, and a suction cup fixed to the end of the rubber rod away from the first connecting block.

[0012] By adopting the above technical solution, after pressing the suction cup and making it firmly adhere to the inner wall of the vacuum cleaner housing, the purpose of fixing the branch sections of the intermediate wire harness and the branch wire harness to the inner wall of the vacuum cleaner housing is achieved.

[0013] Furthermore, a pull rod is fixed to the outer wall of the suction cup, and the end of the pull rod away from the suction cup is spherical, with the diameter of the sphere being larger than the diameter of the pull rod.

[0014] By adopting the above technical solution, the pull rod is designed to facilitate the staff to pull the suction cup and release air, so as to disassemble the branch sections of the intermediate wire harness and the branch wire harness.

When the first connecting block and the second connecting block are fixed by the fixing component, the first auxiliary block and the second auxiliary block are fixed together, ensuring the connection stability and regularity of the wire harness group before it is split.
