Description

Technical Field

[0001] This application relates to a vacuum cleaner accessory and a corresponding vacuum cleaner, and more particularly to the design of the interface portion of the vacuum cleaner accessory. Background Technology

[0002] An existing vacuum cleaner accessory is hollow, forming an airflow channel extending from one end of the accessory to the other. The accessory includes a first interface portion, a second interface portion, and an annular connecting wall connecting the first and second interface portions. The first interface portion can be inserted as a female connector to a pipe interface, and the second interface portion can be inserted as a female connector to another pipe interface, allowing the vacuum cleaner accessory to selectively connect to two different pipe interfaces of different diameters. The first and second interface portions are coaxially arranged, with the first interface portion extending from the annular connecting wall towards the said end of the vacuum cleaner accessory, and the second interface portion at least partially protruding beyond the annular connecting wall towards the said end of the vacuum cleaner accessory. On one side of one end, because at least a portion of the second interface protrudes from the side of the annular connecting wall facing the vacuum cleaner accessory, if the other tubing interface needs to be inserted very deeply (e.g., into the annular connecting wall), it may be blocked by the small portion of the second interface after entering the first interface, making it difficult to insert properly. Furthermore, after the tubing interface extends into the first interface, it may also become partially stuck between the inner circumference of the first interface and the outer circumference of at least a portion of the second interface, making it difficult to adjust its position to smoothly align with the second interface. This hinders the smooth insertion of the tubing interface into the second interface. Therefore, existing vacuum cleaner accessories need improvement to enhance the user experience of connecting to the tubing interface. Utility Model Content

[0003] The technical problem addressed by this application is to improve the design of vacuum cleaner accessories to enhance the user experience of connecting vacuum cleaner accessories to tubing interfaces.

[0004] This application provides a vacuum cleaner accessory having an airflow channel extending from one end of the accessory to the other end. The vacuum cleaner accessory can be selectively plugged into a first pipe interface, a second pipe interface, or a third pipe interface. The vacuum cleaner accessory includes a first interface portion and a second interface portion. The first interface portion can be plugged into the first pipe interface as a male connector, or into the second pipe interface as a female connector, or into the third pipe interface as a female connector. The inner diameter of the first interface portion is larger than the inner diameter of the second interface portion. The vacuum cleaner accessory also includes an annular connecting wall connecting the first and second interface portions. The first interface portion, the second interface portion, and the annular connecting wall are all arranged around a central axis, which is a virtual straight line. At least a portion of the first interface portion extends from the annular connecting wall towards one end of the vacuum cleaner accessory. The second interface portion does not protrude from the side of the annular connecting wall facing the one end of the vacuum cleaner accessory. The second interface portion extends from the annular connecting wall away from the one end of the vacuum cleaner accessory.

[0005] This design allows the vacuum cleaner accessory to selectively connect to three different pipe interfaces via a first interface portion that can function as a male / female connector and a second interface portion that can function as a female connector, making it more practical. Furthermore, since at least a portion of the first interface portion extends from the annular connecting wall towards one end of the vacuum cleaner accessory, and the second interface portion does not protrude from the side of the annular connecting wall facing the end of the vacuum cleaner accessory, but extends away from the end of the vacuum cleaner accessory from the annular connecting wall, it helps prevent the third pipe interface from partially getting stuck after being inserted into the first interface portion, as is common in the prior art. This allows for easier and smoother alignment and insertion into the second interface portion, and also avoids the problem in the prior art where the second interface portion might obstruct the insertion of the second pipe interface. In summary, this design improves the user experience of connecting the vacuum cleaner accessory to the pipe interfaces.

[0006] Optionally, the first interface portion and the second interface portion are coaxially arranged, and the central axis constitutes the central axis of the first interface portion. The first interface portion is cylindrical, and the second interface portion is cylindrical. The first interface portion, the annular connecting wall, and the second interface portion are integrally formed and sequentially connected. The first interface portion extends from the outer periphery of the annular connecting wall toward one end of the vacuum cleaner accessory, and the second interface portion extends from the inner periphery of the annular connecting wall toward one end away from the vacuum cleaner accessory. The one end of the vacuum cleaner accessory constitutes the free end of the first interface portion.

[0007] Optionally, the annular connecting wall is perpendicular to the central axis, and the inner diameter of the first interface portion is larger than the outer diameter of the second interface portion.

[0010] Optionally, the inner surface of the annular connecting wall is perpendicular to the central axis, and the outer surface of the annular connecting wall is perpendicular to the central axis.

[0011] Optionally, the first interface portion has an outer peripheral surface, and the diameter of the outer peripheral surface of the first interface portion gradually narrows from the annular connecting wall to one end of the vacuum cleaner accessory; the outer peripheral surface of the first interface portion can be adapted to fit the first pipe interface so that the first pipe interface can be used as a female plug on the outer peripheral surface of the first interface portion; when the first interface portion and the first pipe interface are plugged together, the outer peripheral surface of the first interface portion and the first pipe interface are in contact and bonded together by friction; the outer peripheral surface of the first interface portion is provided with a plurality of indentations, which are distributed in the circumferential direction of the first interface portion.

[0012] Optionally, the first interface portion has an inner peripheral surface, and the diameter of the inner peripheral surface of the first interface portion gradually expands from the annular connecting wall to one end of the vacuum cleaner accessory; the inner peripheral surface of the first interface portion can be adapted to the second pipe interface so that the second pipe interface can be fitted as a male plug by the inner peripheral surface of the first interface portion; when the first interface portion and the second pipe interface are plugged together, the inner peripheral surface of the first interface portion and the second pipe interface are in contact and bonded together by friction.

[0013] Optionally, the second interface portion has an inner peripheral surface whose diameter gradually shrinks in a direction away from the annular connection wall. The inner peripheral surface of the second interface portion can be adapted to a third pipeline interface so that the third pipeline interface can be used as a male socket and be sleeved by the inner peripheral surface of the second interface portion. When the second interface portion and the third pipeline interface are plugged together, the inner peripheral surface of the second interface portion is in contact with the third pipeline interface and is combined together by frictional force.

[0014] Optionally, the vacuum cleaner accessory further includes a lighting component. The lighting component is exposed outside the vacuum cleaner accessory.

[0020] See Figures 1 to 4The vacuum cleaner accessory 1 shown in this application is hollow and has an airflow channel 12 extending from one end 10 to the other end 11. The vacuum cleaner accessory 1 can be selectively plugged into a first pipe interface, a second pipe interface, or a third pipe interface. The inner diameter of the first pipe interface is larger than the outer diameter of the second pipe interface, and the outer diameter of the second pipe interface is larger than the outer diameter of the third pipe interface. The vacuum cleaner accessory 1 includes a first interface portion 2 and a second interface portion 3, and the airflow channel 12 passes through both the first interface portion 2 and the second interface portion 3. The first interface portion 2 can be used as a male connector to be plugged into the first pipe interface, and the first interface portion 2 can also be used as a female connector to be plugged into the second pipe interface. The interfaces are plugged together, and the second interface 3 can be plugged into the third pipeline interface as a female connector; the inner diameter of the first interface 2 is larger than the inner diameter of the second interface 3. The vacuum cleaner accessory 1 also includes an annular connecting wall 4 connecting the first interface 2 and the second interface 3. The first interface 2, the second interface 3 and the annular connecting wall 4 are all around a central axis A, which is a virtual straight line. At least a portion of the first interface 2 extends from the annular connecting wall 4 toward the end 10 of the vacuum cleaner accessory 1. The second interface 3 does not protrude from the side of the annular connecting wall 4 facing the end 10 of the vacuum cleaner accessory 1. The second interface 3 extends from the annular connecting wall 4 in a direction away from the end 10 of the vacuum cleaner accessory 1. With this design, the vacuum cleaner accessory 1 can selectively connect to three different pipe interfaces via a first interface portion 2 that can function as a male / female connector and a second interface portion 3 that can function as a female connector, making it more practical. Furthermore, since at least a portion of the first interface portion 2 extends from the annular connecting wall 4 towards one end 10 of the vacuum cleaner accessory 1, and the second interface portion 3 does not protrude from the side of the annular connecting wall 4 facing the one end 10 of the vacuum cleaner accessory 1, and extends from the annular connecting wall 4 away from the one end 10 of the vacuum cleaner accessory 1, this helps to prevent the third pipe interface from partially getting stuck after it extends into the first interface portion 2, as is common in the prior art. It allows for easier and smoother alignment and connection to the second interface portion 3, and also avoids the problem in the prior art where the second interface portion 3 might obstruct the connection of the second pipe interface. In summary, this design improves the user experience of connecting the vacuum cleaner accessory 1 to the pipe interfaces. Along the axial direction of both the first interface portion 2 and the second interface portion 3, at least a portion of the first interface portion 2 and the second interface portion 3 are located on opposite sides of the annular connecting wall 4. The pipe interface can be one end of a suction hose, or one end of an extension pipe, etc., and will not be described further.

[0021] The first interface portion 2 and the second interface portion 3 are coaxially arranged. The central axis A constitutes the central axis of the first interface portion 2 and also the central axis of the second interface portion 3. The first interface portion 2 is cylindrical and the second interface portion 3 is cylindrical. The first interface portion 2, the annular connecting wall 4, and the second interface portion 3 are made of plastic. The first interface portion 2, the annular connecting wall 4, and the second interface portion 3 are integrally formed and sequentially connected. The first interface portion 2 extends from the outer periphery of the annular connecting wall 4 toward the end 10 of the vacuum cleaner accessory 1. The second interface portion 3 extends from the inner periphery of the annular connecting wall 4 toward the end 10 of the vacuum cleaner accessory 1. The end 10 of the vacuum cleaner accessory 1 constitutes the free end of the first interface portion 2.

[0022] The annular connecting wall 4 is perpendicular to the central axis A, and the inner diameter of the first interface portion 2 is larger than the outer diameter of the second interface portion 3. The annular connecting wall 4 has an inner surface 40, which faces the end 10 of the vacuum cleaner accessory 1 and surrounds the central axis A. The first interface portion 2 has an inner circumferential surface 20, and the second interface portion 3 has an inner circumferential surface 30. The inner circumferential surface 20 of the first interface portion 2 surrounds the central axis A and extends from the inner surface 40 of the annular connecting wall 4 toward the end 10 of the vacuum cleaner accessory 1. The inner circumferential surface 30 of the second interface portion 3 surrounds the central axis A and extends from the inner surface 40 of the annular connecting wall 4 away from the end 10 of the vacuum cleaner accessory 1.

[0023] The annular connecting wall 4 has an outer surface 41 facing away from the end 10 of the vacuum cleaner accessory 1 and surrounding the central axis A. The first interface portion 2 has an outer peripheral surface 21, and the second interface portion 3 has an outer peripheral surface 31. The outer peripheral surface 21 of the first interface portion 2 extends from the outer surface 41 of the annular connecting wall 4 toward the end 10 of the vacuum cleaner accessory 1, and the outer peripheral surface 31 of the second interface portion 3 extends from the outer surface 41 of the annular connecting wall 4 in a direction away from the end 10 of the vacuum cleaner accessory 1.

[0024] The inner surface 40 of the annular connecting wall 4 is perpendicular to the central axis A, and the outer surface 41 of the annular connecting wall 4 is perpendicular to the central axis A. The outer peripheral surface 21 of the first interface portion 2 is provided with a plurality of shallow recesses 210, which are distributed in the circumferential direction of the first interface portion 2. The presence of the recesses 210 helps to enhance the richness and aesthetics of the shape of the outer peripheral surface 21 of the first interface portion 2.

[0025] From the annular connecting wall 4 to one end 10 of the vacuum cleaner accessory 1, the diameter of the outer peripheral surface 21 of the first interface portion 2 gradually decreases; the outer peripheral surface 21 of the first interface portion 2 can be adapted to the first pipeline interface so that the first pipeline interface can be used as a female plug on the outer peripheral surface 21 of the first interface portion 2. This design facilitates the insertion of the first interface portion 2 as a male plug into the first pipeline interface; when the first interface portion 2 and the first pipeline interface are inserted together, the outer peripheral surface 21 of the first interface portion 2 and the first pipeline interface are tightly fitted together and bonded together by friction.

[0026] From the annular connecting wall 4 to one end 10 of the vacuum cleaner accessory 1, the inner circumferential surface 20 of the first interface portion 2 gradually expands in diameter; the inner circumferential surface 20 of the first interface portion 2 can be adapted to the second pipe interface, so that the second pipe interface can be used as a male connector and fitted by the outer circumferential surface 21 of the first interface portion 2. This design facilitates the insertion of the first interface portion 2 as a female connector into the second pipe interface; when the first interface portion 2 and the second pipe interface are inserted together, the inner circumferential surface 20 of the first interface portion 2 and the second pipe interface are tightly fitted and bonded together by friction.

[0027] The inner circumferential surface 30 of the second interface portion 3 gradually narrows in diameter in the direction away from the annular connecting wall 4. The inner circumferential surface 30 of the second interface portion 3 can be adapted to the third pipeline interface, so that the third pipeline interface can be fitted as a male connector by the inner circumferential surface 30 of the second interface portion 3. This design facilitates the second interface portion 3 to be inserted into the third pipeline interface as a female connector; when the second interface portion 3 and the third pipeline interface are inserted into each other, the inner circumferential surface 30 of the second interface portion 3 and the third pipeline interface are tightly fitted together and bonded together by friction.

[0028] The vacuum cleaner accessory 1 also includes a lighting assembly 5, which is exposed on the outside of the vacuum cleaner accessory 1. The lighting assembly 5 is located on the side of the second interface portion 3 away from the first interface portion 2, and the lighting assembly 5 and the annular connecting wall 4 are located at opposite ends of the second interface portion 3 along the axial direction. The lighting assembly 5 includes an indicator light 50 for illumination, a transparent light-transmitting part 51, a battery 52 for powering the indicator light 50, a switch 53 for controlling the indicator light 50 to turn on and off, and a cover 54. The indicator light 50 is located inside the lighting assembly 5, and the light emitted by the indicator light 50 is emitted through the light-transmitting part 51, which is located on the side of the lighting assembly 5 opposite to the annular connecting wall 4. This design facilitates the operation of the vacuum cleaner accessory 1 in low-light environments, improves the user experience, and also helps to prevent damage to the exposed indicator light 50. The switch 53 can be a push switch, button switch, rocker switch, etc.

[0029] The other end 11 of the vacuum cleaner accessory 1 forms a dust suction port, which is used to suck up dust, debris and other garbage from the surface to be cleaned. In this embodiment, the vacuum cleaner accessory 1 is a flat suction head, but it is not limited to this. The vacuum cleaner accessory 1 can also be a claw suction head, a flared suction head, a floor brush head, a brush head, an interface adapter, etc.

[0030] This application also provides a vacuum cleaner that includes the vacuum cleaner accessory 1 as described above.
