Description

Technical Field

[0001] The utility model relates to the technical field of vacuum cleaner auxiliary appliances, in particular to a charging bracket for a handheld vacuum cleaner. Background Art

[0002] Handheld vacuum cleaners, due to their portability and practicality, have become a common cleaning tool in modern households. A handheld vacuum cleaner typically consists of a main unit and necessary vacuum accessories (such as a flat nozzle, a long nozzle, a cleaning brush with a connecting tube, and a connecting hose / hard tube). The main unit typically includes a main body with a handle, a suction nozzle, a filter, a suction motor, and a rechargeable battery pack. Users can connect different vacuum accessories to the main unit to clean various surfaces, such as floors, sofas, coffee tables, and walls. After extended use, users typically place the main unit on a rechargeable rack for charging and store the accessories there. In related art, the rechargeable rack is typically equipped with a charging terminal and a fixed hook for hanging the main unit. If the main unit is not properly attached to the hook or is accidentally subjected to external impact or vibration during hanging, the main unit can easily become loose from the fixed hook and fall off the rechargeable rack. Therefore, traditional rechargeable hangers use fixed hooks to support the handheld vacuum cleaner, which is easily affected by vibration, external force collision, etc., and the fixing effect is less than ideal. Secondly, because the hook is fixed on the rechargeable hanger, the distance between the fixed hook and the charging terminal is usually fixed. Therefore, when handheld vacuum cleaners of different sizes and models are hung on the rechargeable hanger for charging, the charging part of some handheld vacuum cleaners may have poor contact with the charging terminal on the rechargeable hanger. Therefore, traditional rechargeable hangers use fixed hooks to support the handheld vacuum cleaner, which can only adapt to specific models of handheld vacuum cleaners and may not be used for handheld vacuum cleaners of different brands or models, which limits the versatility of the rechargeable hanger.
