Abstract
Description
Technical Field
[0001] This utility model relates to the field of vacuum cleaner base station technology, and in particular to a quick-change connector device. Background Technology
[0002] Cordless handheld vacuum cleaners have brought great convenience to people's lives. However, during use, the dust cup continuously accumulates dust. When the dust cup is nearing its capacity, consumers often tilt it to empty the dust and debris, which can soil their hands and clothes and cause dust to spill, potentially affecting their health. While existing technology includes dust collection base stations, these stations are often only compatible with a single cordless handheld vacuum cleaner. This leads to a waste of the dust collection base station when consumers switch vacuum cleaners, and also presents technical problems such as requiring significant operating space and inconvenience for consumers to handle. Summary of the Invention
[0003] The purpose of this invention is to provide a quick-change connector device that facilitates the replacement and adaptation of various types of cordless handheld vacuum cleaners, while reducing the operating space and making it easier to pick up the vacuum cleaner.
[0004] To achieve the above objectives, the technical solution adopted by this utility model is: a quick-change connector device, comprising: a connector body, a dust guiding channel located inside the connector body, and a base plate for contacting the dust collection base station and having a dust discharge port. The dust discharge port of the base plate located at the bottom of the connector body is connected to the dust guiding channel. The base plate is rotatably connected to the dust collection base station. The side surface of the connector body has a left support portion and a right support portion arranged opposite to each other. The left support portion, the connector body, and the right support portion form a receiving cavity. A dust inlet is located on the inner side of the receiving cavity. There is a gap between the ends of the left support portion and the right support portion that are away from the connector body.
[0005] The following are further improvements to the above technical solution:
[0006] 1. In the above scheme, the bottom of the accommodating cavity has a flange.
[0007] 2. In the above scheme, the shape of the left support part is arc-shaped, and the shape of the right support part is arc-shaped.
[0008] 3. In the above scheme, the width of the gap is greater than the diameter of the vacuum cleaner's suction tube.
[0009] 4. In the above scheme, the bottom plate has a dust guide pipe, and the dust discharge port that can be embedded in the dust collection base station is located at the lower end of the dust guide pipe.
[0010] 5. In the above scheme, the connector body includes a housing and a cover plate located on the upper part of the housing.
[0011] Due to the application of the above technical solution, this utility model has the following advantages compared with the prior art:
[0012] This utility model's quick-change connector device has a base plate that is rotatably connected to the dust collection base station. The side surface of the connector body has a left support and a right support arranged opposite to each other. The left support, the connector body, and the right support form a receiving cavity. A dust inlet is located on the inner side of the receiving cavity. There is a gap between the ends of the left and right supports that are away from the connector body. This design facilitates the replacement and adaptation of various types of cordless handheld vacuum cleaners. When the base station is placed against a wall, both the front of the base station and the vacuum cleaner face the consumer, reducing the operating space and improving the overall aesthetics. It also makes it convenient for users to place the vacuum cleaner on the dust collection base station and to retrieve it for subsequent use. Furthermore, the bottom of the receiving cavity has a flange, which increases the contact area between the vacuum cleaner and the quick-change connector device, resulting in more even force distribution and extending the service life.

[0017] The present patent can be further understood through the specific embodiments given below, but they are not intended to limit the present patent.
[0018] Example 1: A quick-connect coupling device includes: a coupling body 1, a dust guiding channel 2 located inside the coupling body 1, and a base plate 3 for contacting a dust collection base station and having a dust discharge port 301. The dust discharge port 301 of the base plate 3 located at the bottom of the coupling body 1 is connected to the dust guiding channel 2. The base plate 3 is rotatably connected to the dust collection base station. The side surface of the coupling body 1 has a left support portion 41 and a right support portion 42 arranged opposite to each other. The left support portion 41, the coupling body 1, and the right support portion 42 form a receiving cavity 6. A dust inlet 7 is located on the inner side of the receiving cavity 6.
