Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like or similar reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are illustrative and intended to be illustrative of the invention and are not to be construed as limiting the invention.

An upright cleaner 100 according to an embodiment of the present invention will be described with reference to fig. 1 to 6.

As shown in fig. 1, an upright type cleaner 100 according to an embodiment of the present invention includes: the device comprises a frame 1, a main machine component 2, a floor brush component 3, a first telescopic pipe 4 and a second telescopic pipe 5.

Specifically, the frame 1 extends in the up-down direction; the main machine component 2 is arranged on the frame 1, the main machine component 2 can move up and down relative to the frame 1, and the floor brush component 3 is arranged at the bottom of the frame 1. Wherein, host computer subassembly 2 can include dirt cup subassembly 21 and motor element, wherein dirt cup subassembly 21 includes dirt cup 211, dirt cup 211 is linked together with scrubbing brush subassembly 3, motor element is arranged in dust, impurity and the air entering scrubbing brush subassembly 3 in the drive scrubbing brush subassembly 3 outside, then inhale in the dirt cup subassembly 21 again, dirt cup subassembly 21 separates dust and impurity from the air, at this moment, clean air can directly discharge or flow through motor element and discharge after for motor element heat dissipation, simultaneously, impurity and dust are then stayed in dirt cup subassembly 21.

Further, the first telescopic tube 4 is telescopic, for example, the first telescopic tube 4 is telescopic along the length direction thereof, 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 and communicated with the floor brush assembly 3, 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 up-and-down direction relative to the machine frame 1, for example, the lower end of the first telescopic tube 4 can be connected to the outlet of the airflow chamber of the floor brush assembly 3, and the upper end of the first telescopic tube 4 can be movably arranged on the machine frame 1 in the up-and-down direction.

Further, the second extension tube 5 is extendable and retractable, for example, in a length direction thereof (e.g., up and down direction shown in fig. 6), one end of the second extension tube 5 (e.g., upper end of the second extension tube 5 shown in fig. 6) is connected and communicated with the dust cup 211 of the main unit assembly 2, the other end of the second extension tube 5 (e.g., lower end of the second extension tube 5 shown in fig. 6) is movable in an up and down direction with respect to the frame 1, and the other end of the second extension tube 5 (e.g., lower end of the second extension tube 5 shown in fig. 6) is connected and communicated with the other end of the first extension tube 4 (e.g., upper end of the first extension tube 4 shown in fig. 6). For example, the lower end of the second extension tube 5 can be movably disposed on the frame 1 along the up-down direction, the lower end of the second extension tube 5 is connected to the upper end of the first extension tube 4, and the upper end of the second extension tube 5 is connected to the dust cup 211 of the dust cup assembly 21.

Thus, in the process of using the vertical vacuum cleaner 100, when the height of the main unit assembly 2 needs to be adjusted, the main unit assembly 2 can be manually pulled or driven by a driving part to move upwards along the frame 1, and at the moment, as the main unit assembly 2 moves upwards, the second telescopic pipe 5 can extend to match the upwards movement of the main unit assembly 2, so as to ensure that the floor brush assembly 3 is always communicated with the dust cup 211 of the main unit assembly 2; after the second extension tube 5 is extended to a predetermined length, if the main unit assembly 2 continues to move upwards, the first extension tube 4 can also be extended to match the upward movement of the main unit assembly 2, so that the moving distance of the main unit assembly 2 in the vertical direction can be increased, the main unit assembly 2 can move to the top of the frame 1, the upright vacuum cleaner 100 can also work like a handheld vacuum cleaner, and the collision and interference between the main unit assembly 2 and the floor brush assembly 3 or furniture in the cleaning process can be avoided.

Here, it should be noted that, regarding the process of moving the main unit assembly 2 upwards, for convenience of description, a sequence of extending the second extension tube 5 first and extending the first extension tube 4 later is adopted, but the present invention is not limited thereto, and the extending sequence of the first extension tube 4 and the second extension tube 5 is not limited at all, that is, during the process of moving the main unit assembly 2 upwards, the first extension tube 4 may be extended first and the second extension tube 5 is extended later, or the first extension tube 4 and the second extension tube 5 may be extended simultaneously to match the upward movement of the main unit assembly 2.
