[0037] The present invention will now be described in detail with reference to the embodiments shown in the accompanying drawings. However, these embodiments do not limit the present invention, and any modifications to the mechanism, method, or function made by those skilled in the art based on these embodiments are included within the protection scope of the present invention.

[0038] The terms used herein, such as "up," "down," "left," "right," "front," and "back," indicating spatial relative position, are for illustrative purposes to describe the relationship of one feature relative to another, as shown in the accompanying drawings. It is understood that, depending on the product's placement, these terms may be intended to include different orientations besides those shown in the figures, and should not be construed as limiting the claims. Furthermore, the descriptive term "horizontal" used herein is not entirely equivalent to being perpendicular to the direction of gravity, and allows for a certain angle of inclination.

[0039] like Figure 1-3 As shown, this utility model provides a cleaning device, which includes an accessory 100. When the cleaning device is in operation, a negative pressure is generated inside, enabling the accessory 100 to suck up dirt. When using the cleaning device, the user manipulates the accessory 100 close to the location of the dirt, and the accessory 100 can then suck up the dirt.

[0040] Attachment 100 includes a suction port 10, an interface portion 50, and an elongated body 20 connecting the suction port 10 and the interface portion 50. The suction port 10 is used to suck up dirt, and the interface portion 50 is used to connect to the main body of the cleaning device. The elongated body 20 is a long, thin strip that occupies most of the length of attachment 100 and connects the suction port 10 and the interface portion 50. The dirt sucked up by the suction port 10 can flow into the interior of the cleaning device sequentially through the elongated body 20 and the interface portion 50. In this embodiment, the cleaning device can be a vacuum cleaner.

[0041] The elongated body 20 includes a flexible segment 30 located near the suction port 10. The flexible segment 30 is a bendable part of the elongated body 20. Under the action of external force, the flexible segment 30 can bend and deform. As the flexible segment 30 bends, the position of the suction port 10 can change accordingly, so that the suction port 10 can reach the bottom of furniture and near the corner of the wall to suck up dirt.

[0042] The flexible segment 30 includes a plurality of support ribs 31 and a plurality of stiffeners 32. The plurality of support ribs 31 are in a ring shape and are spaced apart along the length of the elongated body 20. The plurality of stiffeners 32 connect adjacent support ribs 31, thereby connecting the plurality of support ribs 31 together. Furthermore, the stiffeners 32 are disposed on at least one side of the elongated body 20, and the flexible segment 30 is at least able to bend to that side.

[0043] It is understandable that in one implementation, such as Figures 1-8 As shown, multiple staggered stiffeners 32 can be used to connect multiple spaced support ribs 31.

[0044] In another implementation, such as Figures 9-11 As shown, multiple continuously arranged stiffeners 32 can be used to connect multiple spaced support ribs 31, and the extension direction of the stiffeners 32 is generally parallel to the length direction of the slender body 20.

[0045] Ribs 32 are disposed on at least one side of the elongated body 20, and multiple support ribs 31 are connected to the ribs 32 on that side. Ribs 32 may be disposed on only one side of the elongated body 10, or on multiple sides of the elongated body 20. The flexible segment 30 may be able to bend only toward the side of the elongated body 10 where ribs 32 are disposed, or it may be able to bend not only toward the side of the elongated body 10 where ribs 32 are disposed, but also toward other sides of the elongated body 10 where ribs 32 are not disposed.

[0046] With the above configuration, the area between two adjacent support ribs 31, except for the stiffener 32, is hollow. The flexible section 30 is easy to bend at the stiffener 32, so that the flexible section 30 can be easily bent towards the side of the slender body 20 where the stiffener 32 is provided, and a large bending range can be guaranteed.

[0047] It should be noted that, in this article, the length direction of the slender body 20 is the direction in which the slender body 20 is located. Figure 1 In the state shown, the width direction of the slender body 20 is in the left-right direction, and the width direction of the slender body 20 is in the position shown. Figure 1 The vertical direction of the slender body 20 in the shown state, and the height direction of the slender body 20 in the state shown. Figure 3 The left and right directions in the state shown.

[0048] When using the accessory 100 provided in this embodiment, the operator can bend the flexible section 30 with less effort, and the flexible section 30 can be bent to a large extent. When using the accessory 100, the flexible section 30 can bend according to the actual cleaning environment, so that the suction port 10 can reach narrow or irregular spaces such as the bottom of furniture and corner gaps, thereby improving the cleaning effect of the cleaning equipment and the user experience.

[0049] In this embodiment, the elongated body 20 is flat, and the stiffener 32 is disposed on at least one flat surface 21 of the elongated body 20. When the flexible segment 30 is bent, it forms an angle with the flat surface 21. The stiffener 32 may be disposed on one flat surface 21, or it may be disposed on two or more flat surfaces 21.

[0050] When the flexible segment 30 is bent, it forms an angle with the flat surface 21. This can be understood as the flexible segment 30 deviating from the flat surface 21 when it is bent, thus forming an angle with the flat surface 21.

[0051] The slender body 20 is flat, meaning its height is less than its width, and the flat surface 21 is located in the height direction of the slender body (e.g., Figure 3 (as shown) at least one side. As at least part of the elongated body 20, the flexible segment 30 is also flat and its height is less than its width. In this case, the flexible segment 30 can be bent relatively easily to the side in its height direction (i.e., the side where the flat surface 21 is located).

[0052] Continue to combine Figure 3-7 As shown, the elongated body 20 includes two opposing flat surfaces 21, located on opposite sides of the height of the elongated body 20. Adjacent support ribs 31 are connected by at least two stiffening plates 32, which are located on the two flat surfaces 21. In other words, the at least two stiffening plates 32 connecting adjacent support ribs 31 are located on opposite sides of the height of the elongated body 20. The flexible segment 30 can be bent to both sides of the height of the elongated body 20 to form angles with the two flat surfaces 21.

[0053] In this embodiment, two adjacent support ribs 31 are connected by two stiffening plates 32. In other embodiments, the number of stiffening plates 32 connecting two adjacent support ribs 31 may be three or even more.

[0054] With the above configuration, the flexible section 30 can be bent at least to both sides in the height direction of the slender body 20, with greater bending flexibility. The accessory 100 can better adapt to the clean environment. Furthermore, the two adjacent support ribs 31 are connected by at least two stiffeners 32, ensuring the connection strength between the two adjacent support ribs 31.

[0055] It should be noted that the flexible segment 30 can also be bent to both sides of the width direction of the slender body 20. However, since the stiffeners 32 are located on both sides of the height direction of the flexible segment 30, the force required to drive the flexible segment 30 to bend to both sides of the width direction of the slender body 20 is greater than the force required to drive the flexible segment 30 to bend to both sides of the height direction of the slender body 10.

[0056] In this embodiment, at least two stiffening plates 32 connecting two adjacent support ribs 31 also extend along the width direction of the elongated body 20 (e.g., Figure 1 As shown, the stiffeners 32 are staggered, so that the distribution of the stiffeners 32 between two adjacent support ribs 31 is relatively uniform, and the flexible section 30 can maintain its structural stability when bent. The width direction of the slender body 20 is perpendicular to the height direction of the slender body 20.

[0057] It should be noted that at least two stiffening plates 32 are staggered along the width direction of the slender body 20, which can also be understood as at least two stiffening plates 32 being spaced apart along the width direction of the slender body 20. If two adjacent support ribs 31 are connected by two stiffening plates 32, then the two stiffening plates 32 are located on both sides of the width direction of the slender body 20.

[0058] like Figure 6-7 As shown, in one embodiment of the utility model, at least two stiffening plates 32 connecting two adjacent support ribs 31 include a first stiffening plate 32a and a second stiffening plate 32b, which are located on both sides of the slender body 20 in the width direction. Multiple support ribs 31 include adjacent first support ribs 31a, second support ribs 32b, and third support ribs 32c. The first support ribs 31a and second support ribs 32b are connected by the first stiffening plate 32a and the second stiffening plate 32b, and the second support ribs 32b and third support ribs 32c are connected by the first stiffening plate 32a and the second stiffening plate 32b.

[0059] Specifically, the first stiffening plate 32a connecting the first support rib 31a and the second support rib 32b and the first stiffening plate 32a connecting the second support rib 32b and the third support rib 32c are respectively located on two flat surfaces 21, and the second stiffening plate 32b connecting the first support rib 31a and the second support rib 32b and the second stiffening plate 32b connecting the second support rib 32b and the third support rib 32c are respectively located on two flat surfaces 21.

[0060] With the above arrangement, the adjacent first stiffeners 32a are located on two flat surfaces 21 respectively, and the two adjacent second stiffeners 32b are located on two flat surfaces 21 respectively. The first stiffeners 32a and the second stiffeners 32b are arranged alternately, rather than being located on only one flat surface 21, so that the structure of the flexible segment 30 can be more stable and the load-bearing capacity of the flexible segment 30 for external forces in all directions is more balanced.

[0061] The first support rib 31a, the second support rib 32b, and the third support rib 32c can be any three adjacent support ribs 31. Among the multiple support ribs 31, the stiffening plates 32 between any three support ribs 31 are distributed in the manner described above. The distribution of the stiffening plates 32 on the entire flexible section 30 has a certain regularity, and the structure of the flexible section 30 is relatively stable.

[0062] As can be imagined, in other embodiments of this utility model, the first support rib 31a, the second support rib 32b, and the third support rib 32c may be just three adjacent support ribs 31 among a plurality of support ribs 31. On the flexible segment 30, in addition to the first support rib 31a, the second support rib 32b, and the third support rib 32c, there are other plurality of support ribs 31. The stiffeners 32 between the other plurality of support ribs 31 may be distributed in other ways.

[0063] like Figure 3-5 As shown, in another embodiment of this utility model, the following configuration can also be made: at least two stiffening plates 32 connecting the first support rib 31a and the second support rib 32b are located on one of the two flat surfaces 21, and at least two stiffening plates 32 connecting the second support rib 32b and the third support rib 32c are located on the other of the two flat surfaces 21.

[0064] Let the two oppositely arranged flat surfaces 21 be the first flat surface and the second flat surface. With the above arrangement, along the length direction of the slender body 20, the stiffeners 32 on the first flat surface and the stiffeners 32 on the second flat surface are arranged alternately. This is beneficial for the flexible segment 30 to bend to both sides in the height direction of the slender body 20.

[0065] In this embodiment, the attachment 100 includes a first protruding ring 101 and a second protruding ring 102 protruding from its outer periphery, and a flexible sleeve (not shown in the figure) covering the flexible segment 30. The flexible sleeve can be made of a flexible material such as rubber, which can protect the flexible segment 30 and ensure that the dirt does not overflow from the flexible segment 30 when the attachment 100 absorbs dirt. The first protruding ring 101 and the second protruding ring 102 are respectively located on both sides of the flexible sleeve along its length. The second protruding ring 102 can define the position of the flexible sleeve relative to the flexible segment 30, so that the position of the flexible sleeve can remain stable.

[0066] like Figure 2 As shown, the elongated body 20 also includes a connecting section 40 that connects the flexible section 30 and the interface section 50. The connecting section 40 forms a transition between the flexible section 30 and the interface section 50, increasing the length of the elongated body 20 and enabling the suction port 10 to penetrate into certain crevices and suck up dirt from the depth of the crevices.

[0067] like Figure 7-8 As shown, the dimension occupied by the stiffener 32 in the height direction of the slender body 20 is H, and the dimension occupied by the stiffener 32 in the width direction of the slender body 20 is W, where H / W = 0.2~0.6.

[0068] The dimension occupied by the stiffening rib 32 in the height direction of the slender body 20 is the thickness of the stiffening rib 32, and the dimension occupied by the stiffening rib 32 in the width direction of the slender body 20 is the width of the stiffening rib 32. The thickness and width of the stiffening rib 32 adopt the above ratio, which can ensure the connection strength between two adjacent support ribs 31 and the bending performance of the flexible section 30. As a preferred embodiment, the dimension occupied by the stiffening rib 32 in the height direction of the slender body 20 is 1.9 mm, and the dimension occupied by the stiffening rib 32 in the width direction of the slender body 20 is 4 mm.

[0069] It should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This way of describing the specification is only for clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.

[0070] The above embodiments are only used to illustrate the technical solutions of this application and are not intended to limit it. Although this application has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this application without departing from the spirit and scope of the technical solutions of this application.
