Description

[0001] This application is a divisional application of the Chinese invention patent with application number: 201911415864.9, named "A vacuum cleaner hanger assembly", and application date of December 31, 2019. Technical Field

[0002] The invention relates to a vacuum cleaner hanger assembly, in particular to a multifunctional hanger used in conjunction with a handheld vacuum cleaner. Background Art

[0003] Among the existing vacuum cleaners, handheld vacuum cleaners are gradually favored by users in home and vehicle applications due to their small size and convenience. In particular, battery-driven wireless handheld vacuum cleaners are free from the limitation of wire length and can flexibly clean every corner. Currently, handheld vacuum cleaners are widely used in home life. The existing handheld vacuum cleaners include a main unit, a vacuum pipe and a suction head. When in use, they are assembled together. After use, they are disassembled and placed in order to save space. This requires a hanger to store and place the disassembled parts.

[0004] There are several types of existing handheld vacuum cleaner hangers: the first type is a floor-standing hanger, which stands on the ground where the storage space is located through the counterweight of the support base, and the hanger itself is not fixed, and its characteristic is that it can be easily moved. For example, Chinese utility model patent CN206473268U discloses a storage seat for a handheld vacuum cleaner, which includes a support base and a pillar, the support base is provided with a support surface, the pillar is connected to the support base, the axial direction of the pillar is perpendicular to the support surface or inclined to the center of the support surface, and the pillar is provided with a bracket for storing the handheld vacuum cleaner.

[0005] The second type is a wall-mounted mount, which is fixedly mounted on the wall. Compared with a floor-standing mount, it has an advantage in saving storage space. For example, Chinese invention patent CN102188189A discloses a wall-mounted mount that is a docking station that also has a charging function. The body where the dust cup is located is fixed to the wall mount through a more complex design such as a bias spring mechanism.

[0006] Although the aforementioned existing handheld vacuum cleaner hangers all have the function of storage, the floor-standing hangers occupy a large storage space. They are movable devices with a high center of gravity, and they may still topple over under external force, causing safety hazards. Although the existing wall-mounted hangers solve the problems of space occupation and loose fixation of the vertical hangers, they are generally equipped with multiple spring clips for clamping the vacuum cleaner inside them. The handheld vacuum cleaner is clamped inside them by multiple spring clips, resulting in a complex structure of such wall hangers, high processing costs, and frequent movements of the clips will also reduce the service life of the hanger.

[0007] It can be seen that the aforementioned existing handheld vacuum cleaner hanger obviously has the inconvenience and defects of occupying a large space or having a complex structure and a short service life, and further improvement is urgently needed.

[0008] The existing charging devices for cordless handheld vacuum cleaners are roughly divided into two types, namely, a seat-type charging device and a hanging-type charging device. The charging device for cordless handheld vacuum cleaners often also has a storage function. The existing seat-type charging device is more convenient to move, but occupies a large space. The hanging-type charger occupies less space, but in order to be able to firmly hang the vacuum cleaner on the wall, the existing hanging-type charger structure is usually more complicated and the processing cost is higher.

[0009] Therefore, there is an urgent need for a hanging charger for a vacuum cleaner that occupies a small space, has a simple structure, is widely applicable, and has a low processing cost. Summary of the invention
