Detailed Implementation

[0033] The specific embodiments of this application will be further described in detail below with reference to the accompanying drawings, so as to make the technical solution of this application easier to understand and master. It should be understood that the specific embodiments described herein are only used to explain this application and are not intended to limit this application.

[0034] This application provides a connector and a vacuum cleaner using the connector, as shown in Figures 1-11. The connector is used to connect the vacuum cleaner's body 100 and a vacuuming accessory 200. The vacuuming accessory 200 includes a hose, a straight tube, a vacuum head, etc., and has a connecting tube that connects to the connector. In this embodiment, one end of the connector has a threaded structure that connects to the connecting tube.

[0035] The connector includes a tube body 300 and a retaining ring 400. The retaining ring 400 has a fixing part 410 and a connecting part 420. The fixing part 410 is fixed to the outside of the tube body 300. There is an installation gap 440 between the connecting part 420 and the outside of the tube body 300. The connecting part 420 has multiple fixing structures. The vacuum cleaner's barrel 100 has a connector 110. The tube body 300 is inserted into the connector 110. The connector 110 is inserted into the installation gap 440 between the tube body 300 and the retaining ring 400. The connector 110 has a connecting structure that is fixedly engaged with one of the multiple fixing structures.

[0036] The fixing structure in this embodiment includes all of the following types of fixing structures. In other optional embodiments, the fixing structure may also be two or three of the following fixing structures.

[0037] As shown in Figures 1-4, the fixing structure includes an internal thread 421 located inside the connecting part 420. As shown in Figure 4, the corresponding connector 110 of the barrel 100 has an external thread 111. The internal thread 421 and the external thread 111 can achieve a detachable connection between the connector and the barrel 100 through threaded engagement.

[0038] As shown in Figures 1-3, the connecting part 420 includes a main ring body 422 and a snap-fit ​​part 423. A break 427 is provided between the snap-fit ​​part 423 and the main ring body 422. The snap-fit ​​part 423 extends away from the fixing part 410 to form an operating part 430. The fixing ring 400 is integrally formed on the tube body 300. The connector is made of plastic. Based on the deformation capability of the connector material itself, the snap-fit ​​part 423 and the operating part 430 form a lever effect. Controlling the operating part 430 allows the snap-fit ​​part 423 to deform away from or towards the tube body 300. In other optional embodiments, the fixing ring 400 can also be separately fixed or welded to the tube body 300.

[0039] As shown in Figures 3, 5, and 6, the fixing structure includes an inner snap-fit ​​424 located on the inner side of the snap-fit ​​portion 423. A retaining rib 112 is provided on the connector 110 of the corresponding vacuum cleaner barrel 100. The inner snap-fit ​​424 and the retaining rib 112 cooperate to achieve a snap-fit ​​engagement between the connector and the barrel 100. The inner snap-fit ​​424 or the retaining rib 112 has corresponding guide bevels to facilitate the connector's insertion into the connector 110. To disassemble the connector and connector 110, simply press the operating part 430. The inner snap-fit ​​424 can also be part of the internal thread 421.

[0040] As shown in Figures 3 and 7-9, the fixing structure includes an outer buckle 425 located on the outer side of the snap-fit ​​part 423. The corresponding connector 110 of the vacuum cleaner's barrel 100 has a protrusion 113 with an insertion port 114. The snap-fit ​​part 423 is inserted into the insertion port 114, causing the outer buckle 425 to engage with the outer end of the protrusion 113. The outer buckle 425 or the protrusion 113 has corresponding guide slopes to facilitate the connector engaging with the connector 110. To disassemble the connector and connector 110, simply lift the operating part 430.

[0041] As shown in Figures 3, 10, and 11, the fixing structure includes a snap-fit ​​hole 426 located on the snap-fit ​​part 423 and having an opening facing the tube body 300. A fixing post 115 is provided on the outer wall of the connector 110 of the corresponding vacuum cleaner barrel 100, and the fixing post 115 is embedded in the snap-fit ​​hole 426. To disassemble the connector and connector 110, press the operating part 430.

[0042] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0043] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
