Detailed ways

The embodiments of the present application are described in detail below. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals indicate the same or similar elements or elements with the same or similar functions. The embodiments described below with reference to the drawings are exemplary, and are intended to explain the present application, but should not be understood as a limitation to the present application.

Hereinafter, an upright vacuum cleaner 100 according to an embodiment of the present application will be described with reference to FIGS. 1 to 6.

As shown in FIG. 1, the vertical vacuum cleaner 100 according to the embodiment of the present application includes: a frame 1, a host assembly 2, a floor brush assembly 3, a first telescopic tube 4 and a second telescopic tube 5.

Specifically, the frame 1 extends in the up and down direction; the host assembly 2 is arranged on the frame 1, and the host assembly 2 is movable in the up and down direction relative to the frame 1, and the floor brush assembly 3 is arranged at the bottom of the frame 1. The host assembly 2 may include a dust cup assembly 21 and a motor assembly. The dust cup assembly 21 includes a dust cup 211. The dust cup 211 is in communication with the floor brush assembly 3, and the motor assembly is used to drive dust and impurities on the outside of the floor brush assembly 3. And air enters the floor brush assembly 3, and then is sucked into the dust cup assembly 21. The dust cup assembly 21 separates dust and impurities from the air. At this time, the clean air can be directly discharged or flow through the motor assembly to dissipate the heat of the motor assembly. At the same time, impurities and dust remain in the dust cup assembly 21.

Further, the first telescopic tube 4 is telescopic, for example, the first telescopic tube 4 is telescopic along its length direction, and one end of the first telescopic tube 4 (for example, the lower end of the first telescopic tube 4 shown in FIG. 6) is connected to the floor brush. The components 3 are connected and communicated. The other end of the first telescopic tube 4 (for example, the upper end of the first telescopic tube 4 shown in FIG. 6) is movable in the vertical direction relative to the frame 1, for example, the first telescopic tube 4 The lower end can be connected to the outlet of the air flow chamber of the floor brush assembly 3, and the upper end of the first telescopic tube 4 can be movably arranged on the frame 1 in the up and down direction.

Further, the second telescopic tube 5 is telescopic, for example, the second telescopic tube is telescopic along its length direction (for example, the up-and-down direction shown in FIG. 6), and one end of the second telescopic tube 5 (for example, as shown in FIG. 6) The upper end of the second telescopic tube 5) is connected to and communicated with the dust cup 211 of the main assembly 2, and the other end of the second telescopic tube 5 (for example, the lower end of the second telescopic tube 5 shown in FIG. 6) is opposite to the frame 1 The vertical direction is movable, and the other end of the second telescopic tube 5 (for example, the lower end of the second telescopic tube 5 shown in FIG. 6) and the other end of the first telescopic tube 4 (for example, the first telescopic tube shown in FIG. 6) The upper end of the tube 4) is connected and communicated. For example, the lower end of the second telescopic tube 5 can be movably arranged on the frame 1 in the up and down direction, and the lower end of the second telescopic tube 5 is connected to the upper end of the first telescopic tube 4, and the upper end of the second telescopic tube 5 is connected to The dust cup 211 of the dust cup assembly 21.

In this way, in the process of using the vertical vacuum cleaner 100, when the height of the main assembly 2 needs to be adjusted, the main assembly 2 can be manually pulled or driven by a driver to move the main assembly 2 upward along the frame 1. At this time, because the main assembly 2 Moving upward, the second telescopic tube 5 can be extended to match the upward movement of the main assembly 2 to ensure that the floor brush assembly 3 and the dust cup 211 of the main assembly 2 are always connected; when the second telescopic tube 5 is extended to a predetermined length If the host assembly 2 continues to move upwards, at this time, the first telescopic tube 4 can also be extended to match the upward movement of the host assembly 2, thereby increasing the moving distance of the host assembly 2 in the up and down direction, so that the host assembly 2 It can be moved to the top of the frame 1 so that the vertical vacuum cleaner 100 can also work like a hand-held vacuum cleaner, thereby avoiding collision and interference between the main assembly 2 and the floor brush assembly 3 or furniture during the cleaning process.

Here, it should be noted that, regarding the process of moving the host assembly 2 upward, for the convenience of description, the sequence of the second telescopic tube 5 being extended first and the first telescopic tube 4 being extended is adopted, but the application is not limited to this.
