[0026] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0027] Combination Figure 1 and Figure 2 According to an embodiment of the present invention, a vacuum cleaner 100 includes: a body 10, a floor brush 20, and an extension tube 30.

[0028] The floor brush 20 has a cleaning direction. It should be noted that, in this application, the cleaning direction of the floor brush 20 is defined as the direction of travel of the floor brush 20 when the user holds the vacuum cleaner 100 to vacuum. For example, the cleaning direction of the floor brush 20 can be a back-and-forth direction. Of course, the cleaning direction in this application does not limit the floor brush 20 to only moving in the cleaning direction. In other words, when actually using the vacuum cleaner 100, the moving direction of the floor brush 20 can be adjusted according to the needs of use.

[0029] The extension tube 30 includes a first tube section 31 and a second tube section 32. The first tube section 31 is connected to the main body 10, and the lower end of the second tube section 32 is connected to the floor brush 20. The upper end of the first tube section 31 is connected to the second tube section 32, and the first tube section 31 and the second tube section 32 are relatively bendable. The vacuum cleaner 100 has an extended state and a bent and retracted state. Figure 1 In the unfolded state, the first pipe section 31 and the second pipe section 32 of the vacuum cleaner 100 are distributed in the vertical direction; combined with Figure 2In the folded and stowed state, the first tube segment 31 and the second tube segment 32 of the vacuum cleaner are distributed along the bending direction, which forms an angle with the cleaning direction. The extension tube 30 may have an airflow channel. For example, the body 10 may include a suction assembly 12 and a dust cup 16. The extension tube 30 is in fluid communication with the brush 20, the dust cup 16, and the suction assembly 12. The first tube segment 31 and the second tube segment 32 are interconnected.

[0030] Specifically, in the unfolded state, the first tube segment 31 and the second tube segment 32 are distributed vertically to facilitate cleaning the work surface using the vacuum cleaner 100. When the vacuum cleaner 100 is not in use, the extension tube 30 can be bent along the bending direction, thus facilitating the storage and folding of the vacuum cleaner 100. The bending direction of the extension tube 30 is as follows: Figure 2 The BB direction shown is the cleaning direction. Figure 2 As shown in the AA direction, the bending direction has an angle with the cleaning direction, which avoids the extension tube 30 from occupying a large space in the cleaning direction after bending, thereby reducing the space occupied by the vacuum cleaner 100 when stored.

[0031] For example, the cleaning direction can be front-to-back, and the bending direction can be left-to-right. Specifically, when the user is using the vacuum cleaner 100, the forward direction of the floor brush 20 is in front of the vacuum cleaner 100, and the side of the vacuum cleaner 100 facing the user is behind the vacuum cleaner 100. The width direction of the floor brush 20 is in the left-to-right direction of the vacuum cleaner 100. The extension tube 30 can be bent towards the left or right side of the vacuum cleaner 100, which can reduce the space occupied by the vacuum cleaner 100 in the bent and stored state, making it easier for the user to store the vacuum cleaner 100. Of course, the bending tube can also be bent towards the left front side of the vacuum cleaner 100, or towards the right front side of the vacuum cleaner 100, etc.

[0032] Combination Figure 2 In some embodiments of this utility model, the bending direction is perpendicular to the cleaning direction, which reduces the space occupied in the cleaning direction when the cleaning device is in the bent and stored state, making it convenient for the user to store the vacuum cleaner 100. For example, the cleaning direction can be front-to-back, and the bending direction can be left-to-right. That is, the first pipe segment 31 can be bent towards the left or right side of the vacuum cleaner 100. After bending, combined with... Figure 5 In the vertical projection, the floor brush 20 and the body 10 can overlap, which can reduce the space occupied by the vacuum cleaner 100 in the front-back direction, making it easier for users to store and store the vacuum cleaner 100.

[0033] Combination Figure 3In some embodiments of this utility model, in the bent and stored state, the first tube segment 31 and the second tube segment 32 are parallel, that is, the first tube segment 31 and the second tube segment 32 are arranged side by side along the bending direction (BB direction), making the structure of the vacuum cleaner 100 more compact and convenient for users to store and store.

[0034] For example, in the bent and stored state, the second tube segment 32 can be connected to the rear side of the floor brush 20, and the second tube segment 32 is set perpendicular to the floor brush 20. The first tube segment 31 is also set perpendicular to the floor brush 20. It can be understood that after the first tube segment 31 is bent, the center of gravity of the body 10 is at the bottom, and the first tube segment 31 and the second tube segment 32 are set parallel to each other, which can improve the stability of the vacuum cleaner 100 in the bent and stored state.

[0035] In addition, the second tube section 32 can be connected to the middle of the rear side of the floor brush 20. The first tube section 31 and the second tube section 32 are arranged in parallel, and the body 10 can be supported on the floor brush 20. On the one hand, this reduces the space occupied by the vacuum cleaner 100, and on the other hand, it can improve the structural stability of the vacuum cleaner 100 when it is bent and stored.

[0036] Optionally, in the folded and stowed state, the angle between the first tube segment 31 and the second tube segment 32 is an acute angle. The first tube segment 31, the second tube segment 32, and the floor brush 20 can form a triangular support, improving the stability of the vacuum cleaner 100 in the folded and stowed state. For example, in the folded and stowed state, the second tube segment 32 can be arranged perpendicularly to the floor brush 20, and the first tube segment 31 is tilted to the left of the floor brush 20 in a downward direction, so that the angle between the first tube segment 31 and the second tube segment 32 is an acute angle. The body 10 can be supported on the floor brush 20, or the body 10 can be supported on the ground.

[0037] In some embodiments of this utility model, in the bent and stored state, the angle between the second tube segment 32 and the cleaning direction of the floor brush 20 is less than 90°. Specifically, the lower end of the second tube segment 32 can be connected to the rear side of the floor brush 20, combined with... Figure 2 As shown, the angle between the second tube section 32 and the floor brush 20 is α. When in the retracted state, the floor brush 20 is in contact with the working surface. The angle α between the second tube section 32 and the cleaning direction AA of the floor brush 20 is less than 90°, which makes it easier to tilt the center of gravity of the vacuum cleaner 100 toward the floor brush 20, thereby improving the stability of the vacuum cleaner 100 in the bent and retracted state.

[0038] Combination Figure 2In some embodiments of this utility model, in the folded and stored state, the body 10 is supported on the floor brush 20. Specifically, in the stored state, the floor brush 20 is in contact with the ground, and the body 10 is supported on the floor brush 20. This reduces the space occupied by the vacuum cleaner 100 and also improves the structural stability of the vacuum cleaner 100 in the folded and stored state. For example, the body 10 can be supported on the upper shell of the floor brush 20.

[0039] Combination Figure 2 Furthermore, the body 10 is provided with a rubber pad 11. In the bent and stored state, the body 10 is supported on the floor brush 20 by the rubber pad 11. By providing the rubber pad 11, on the one hand, the storage stability is improved and the slippage between the body 10 and the floor brush 20 is prevented. On the other hand, it can reduce the wear and tear on the appearance of the body 10 and the floor brush 20 during storage.

[0040] Combination Figure 1 and Figure 4 In some embodiments of this utility model, the body 10 includes a suction assembly 12, a power supply assembly 13, and a handle 14. The suction assembly 12 can be used to provide negative pressure, and the power supply assembly 13 is used to supply power to the suction assembly 12 and other components. Both the power supply assembly 13 and the suction assembly 12 have a certain weight. Placing the handle 14 between the suction assembly 12 and the power supply assembly 13 helps to improve the stability when holding the handle 14 and reduce the burden on the user.

[0041] Combination Figure 4 In the folded and stowed state, the suction component 12 and the power component 13 are respectively located on opposite sides of the second tube segment 32 in the projection along the width direction of the floor brush 20. The width direction of the floor brush 20 is perpendicular to the cleaning direction and the up-down direction. In conjunction with the foregoing, the suction component 12 and the power component 13 are two of the heavier components in the body 10. In the folded and stowed state, the suction component 12 and the power component 13 are distributed on opposite sides, preventing the vacuum cleaner 100 from tipping over due to a shift in the center of gravity of the body 10, thus further improving the stability of the vacuum cleaner 100 in the folded and stowed state.

[0042] Combination Figure 5 In some embodiments of this utility model, in the bent and folded storage state, the suction component 12, handle 14 and power component 13 are arranged along the cleaning direction and surround a recessed space 15. The second tube section 32 is located in the recessed space 15, which can further reduce the storage volume of the vacuum cleaner 100, avoid occupying too much space in the width direction of the floor brush 20, and make the body 10 closer to the center of gravity in the bent and folded storage state, thereby improving the stability of the vacuum cleaner 100 when stored.

[0043] Combination Figure 2In some embodiments of this utility model, the extension tube 30 further includes a flexible tube 33, which connects the first tube segment 31 and the second tube segment 32. The flexible tube 33 is bendable. Specifically, the extension tube 30 is bendable through the flexible tube 33, making it easy for the user to unfold and bend the extension tube 30. For example, the first tube segment 31 and the second tube segment 32 can be configured as straight tubes so that the user can hold the vacuum cleaner 100 to clean the floor when the extension is in the unfolded state.

[0044] Combination Figure 2 and Figure 6 In some embodiments of this utility model, the extension tube 30 further includes a locking structure 34, see reference. Figure 6 In the deployed state, locking structure 34 locks the first pipe segment 31 and the second pipe segment 32, combined with Figure 2 When the vacuum cleaner 100 is in the bent and stored state, the locking structure 34 releases the lock on the first tube segment 31 and the second tube segment 32. When using the vacuum cleaner 100, the first tube segment 31 and the second tube segment 32 can be locked by the locking structure 34. At this time, the extension tube 30 is in a state that cannot be bent, which makes it convenient for the user to use the vacuum cleaner 100 to vacuum. When it is necessary to store the vacuum cleaner 100, the locking structure 34 can release the lock on the first tube segment 31 and the second tube segment 32. At this time, the first tube segment 31 and the second tube segment 32 can be bent relative to each other by the flexible tube 33, which makes it convenient to store the vacuum cleaner 100.

[0045] Combination Figure 1 In some embodiments of this utility model, the body 10 includes a dust cup 16, a suction assembly 12, a power supply assembly 13, and a handle 14. The dust cup 16 and the suction assembly 12 are arranged in a vertical direction. The handle 14 is connected to the suction assembly 12 and the power supply assembly 13 respectively. The power supply assembly 13 and the suction assembly 12 are distributed on opposite sides of the first tube section 31. When the vacuum cleaner 100 is in use, it helps to improve the stability of holding the handle 14 and reduce the burden on the user. When the vacuum cleaner 100 is bent and stored, it prevents the center of gravity of the body 10 from shifting, which would cause the vacuum cleaner 100 to tip over. This improves the stability of the vacuum cleaner 100 in the bent and stored state.

[0046] In some embodiments of this utility model, the body 10 includes a dust cup 16 and a suction assembly 12. The dust cup 16 and the suction assembly 12 are distributed along the cleaning direction and connected to the upper end of the first pipe section 31. Exemplarily, the dust cup 16 is a horizontally placed dust cup 16, and the dust cup 16 and the suction assembly 12 can be distributed along the front-to-back direction, reducing the size occupied by the vacuum cleaner 100 in the height direction, and further reducing the space occupied by the vacuum cleaner 100 in the height direction when it is in a bent and stored state.
