Detailed implementation manners

[0045] The present application will be further described in detail below in conjunction with the drawings through specific implementation manners. Similar elements in different implementation manners are labeled with related similar reference numerals. In the following implementation manners, many detailed descriptions are provided to enable a better understanding of the present application. However, those skilled in the art can easily recognize that some of the features can be omitted in different situations, or can be replaced by other elements, materials, or methods. In some cases, some operations related to the present application are not shown or described in the specification, which is to avoid the core part of the present application being overwhelmed by excessive descriptions. For those skilled in the art, it is not necessary to describe these related operations in detail, and they can fully understand the related operations based on the descriptions in the specification and the general technical knowledge in the art.

[0046] In addition, the features, operations, or characteristics described in the specification can be combined in any appropriate manner to form various implementation manners. At the same time, the steps or actions in the method description can also be reordered or adjusted in an obvious manner by those skilled in the art. Therefore, the various sequences in the specification and the drawings are only for clearly describing a certain embodiment and do not mean a necessary sequence, unless it is stated that a certain sequence must be followed.

[0047] The serial numbers assigned to the components in this article, such as "first", "second", etc., are only used to distinguish the described objects and do not have any sequential or technical meaning. And the "connection" and "coupling" mentioned in the present application, unless otherwise specified, both include direct and indirect connection (coupling).

[0048] In one embodiment, the cleaning robot includes a body, a brush roller, and a wiper blade assembly, wherein the brush roller is rotatably assembled in the body. In one embodiment, please refer to Figure 1and Figure 2 , the squeegee assembly includes a roller brush cover 1, a squeegee bracket 2, and a squeegee 3 for cleaning the ground. The roller brush cover 1 is used to be installed on the body. Please refer to Figure 8 , the roller brush cover 1 has an installation opening 11, and the installation opening 11 is used to install at least a part of the squeegee bracket 2.

[0049] In order to enable the squeegee 3 to adapt to uneven ground, in one embodiment, please refer to Figure 1 , the squeegee bracket 2 is movably installed on the roller brush cover 1. The squeegee bracket 2 has a squeegee installation part 21, and the squeegee 3 is installed on the squeegee installation part 21. The squeegee installation part 21 can float up and down to make the squeegee 3 fit the ground. The squeegee bracket 2 has a roller brush opening 27, and the roller brush opening 27 can expose the roller brush so that the roller brush can perform cleaning work.

[0050] Since the squeegee installation part 21 of the squeegee bracket 2 can float up and down relative to the roller brush cover 1, the squeegee 3 can float up and down. When the cleaning robot encounters uneven ground, the squeegee 3 can keep in contact with the ground, and the cleaning efficiency is high. When passing over a higher ground, the squeegee installation part 21 and the squeegee 3 can float upward, and the force between the squeegee 3 and the ground is not likely to be too large to cause excessive resistance. When passing over a lower ground, the squeegee installation part 21 and the squeegee 3 can float downward, and the lower ground can be cleaned up.

[0051] Regarding the installation method of the squeegee bracket 2, in one embodiment, please refer to Figure 1 , one end of the squeegee bracket 2 is a pivoting end 22 pivotally connected to the roller brush cover 1, and the other end is a floating end 23, and the squeegee installation part 21 is at the floating end 23.

[0052] Furthermore, in one embodiment, please refer to Figures 3 to 6 , at least a part of the squeegee bracket 2 and the roller brush cover 1 are arranged in the thickness direction of the roller brush cover 1. Compared with arranging the whole squeegee bracket 2 in the installation opening 11, arranging at least a part of the squeegee bracket 2 and the roller brush cover 1 along the thickness direction of the roller brush cover 1 can reduce the area of the roller brush cover 1. When ensuring the same area of the roller brush opening 27 to expose the roller brush, the overall volume of the roller brush cover 1 is smaller, and it is also convenient to arrange the squeegee bracket 2 on the roller brush cover 1 with a smaller area.

[0053] Specifically, in one embodiment, please refer to Figure 6 , at least a part of the floating end 23 and the roller brush cover 1 are arranged in the thickness direction of the roller brush cover 1.

[0054] In one embodiment, please refer to Figure 1, an elastic buckle 14 for clamping with the body of the cleaning robot is provided on the roller brush cover 1, and the roller brush cover 1 and the body are clamped and fixed through the elastic buckle 14. A receiving groove 231 is provided at the edge of the floating end 23 of the wiper strip bracket 2. The receiving groove 231 is used to receive the elastic buckle 14 and provide a moving space for the movement of the elastic buckle 14. In some other embodiments, the roller brush cover 1 and the body can be fixed by magnetic attraction, fasteners, etc.

[0055] In one embodiment, please refer to Figure 4 and Figure 7 , in order to make the wiper strip 3 fit the ground better, the wiper strip assembly of the cleaning robot includes an elastic member 4. The elastic member 4 is installed at the pivot end 22, and the elastic member 4 is used to apply an elastic force to the wiper strip bracket 2 to make the wiper strip 3 fit the ground. By applying a pressing force to the ground on the wiper strip bracket 2 through the elastic member 4, it is convenient for the wiper strip 3 to keep fitting the ground and better scrape off stains and garbage on the ground.

[0056] Specifically, in one embodiment, please refer to Figure 1 , Figure 3 , Figure 7 and Figure 8 , the pivot end 22 is provided with a pivot shaft 221. The roller brush cover 1 has a pivot hole 12 adapted to the pivot shaft 221. The elastic member 4 is a torsion spring 40 sleeved on the pivot shaft 221. The torsion spring 40 has a first leg 41 and a second leg 42. The first leg 41 is clamped on the wiper strip bracket 2, and the second leg 42 abuts against the roller brush cover 1. Compared with using a spring, using the torsion spring 40 and sleeving the torsion spring 40 on the pivot shaft 221 can reduce the area of the entire roller brush cover 1. In one embodiment, a hook is provided on the wiper strip bracket 2, and the first leg 41 is snapped into the hook, and the hook can prevent the first leg 41 from moving towards the direction close to the second leg 42. In some other embodiments, a clamping groove can also be provided on the wiper strip bracket, and the first leg is snapped into the clamping groove. In some other embodiments, the first leg 41 can also abut against the wiper strip bracket 2, and the second leg 42 is clamped on the roller brush cover 1.

[0057] In some other embodiments, in addition to using the torsion spring 40, the elastic member 4 can also be a spring or a spring piece, and the spring or the spring piece is installed between the roller brush cover 1 and the wiper strip bracket 2.

[0058] In some other embodiments, in addition to using the elastic member 4, the wiper strip bracket 2 can also rely on gravity to make the wiper strip 3 fit the ground.

[0059] In one embodiment, in order to prevent the floating range of the floating end 23 from being too large, the roller brush cover 1 includes a limiting structure, and the floating end 23 has an adapted structure. The limiting structure limits the moving range of the adapted structure to be able to limit the floating range of the floating end 23.

[0060] Specifically, in one embodiment, please refer toFigure 1 , Figure 3 , Figure 7 and Figure 8 , the squeegee strip 3 extends along the length direction of the squeegee strip bracket 2, and the fitting structure is arranged in the width direction of the squeegee strip bracket 2, which is conducive to arranging at least a part of the floating end 23 and the roller brush cover 1 in the thickness direction of the roller brush cover 1, thereby reducing the area of the roller brush cover 1. One of the limiting structure and the fitting structure is a limiting hole 13, and the other is a limiting part 24 extending into the limiting hole 13, and the limiting part 24 can move relative to the limiting hole 13. In one embodiment, the limiting hole 13 is located on the roller brush cover 1, and the limiting part 24 is located on the squeegee strip bracket 2. In one embodiment, the limiting part 24 is a limiting shaft located on the squeegee strip bracket 2. In one embodiment, the limiting hole 13 is a through hole.

[0061] In some other embodiments, the limiting structure and the fitting structure can also be any other feasible structures. For example, in one embodiment, the limiting structure can also be a limiting shaft, and the fitting structure is a limiting hole. For another example, in one embodiment, the limiting structure can also be two limiting rods, and the fitting structure is a baffle located between the two limiting rods. The baffle moves between the two limiting rods, and the two limiting rods and the baffle stop to limit the movement range of the baffle.

[0062] In one embodiment, please refer to Figure 1 and Figure 6 , the squeegee strip 3 is detachably fixed to the squeegee strip bracket 2. Specifically, the squeegee strip bracket 2 includes a support frame 25 and a positioning frame 26, and the squeegee strip 3 is clamped between the support frame 25 and the positioning frame 26. By clamping the squeegee strip 3, the reliability of the squeegee strip 3 can be better. Compared with the integral molding of the squeegee strip bracket 2 and the squeegee strip 3, when the user needs to replace the squeegee strip 3, the positioning frame 26 can be disassembled to replace the squeegee strip 3.

[0063] Specifically, in one embodiment, please refer to Figure 6 , Figure 9 and Figure 11 , the squeegee strip assembly of the cleaning robot includes a fastener, and the fastener fixes and clamps the positioning frame 26 and the support frame 25. In one embodiment, the fastener is a fastening screw, the positioning frame 26 has a through hole 261 for the fastener to pass through, and the support frame 25 has a fixing hole 251 adapted to the fastening screw. The fastening screw passes through the positioning frame 26 and is screwed into the fixing hole 251 to fix the support frame 25, the positioning frame 26 and the squeegee strip 3 together.

[0064] To facilitate the installation of the squeegee strip 3, in one embodiment, please refer to Figure 10 , the squeegee strip 3 has a first protrusion 31 for positioning and inserting into the support frame 25 and a second protrusion 32 for positioning and inserting into the positioning frame 26. Specifically, please refer to Figure 10, the number of the first protrusions 31 and the second protrusions 32 is both more than two. In some other embodiments, as needed, the scraping strip 3 may only have the first protrusions 31 without the second protrusions 32, and of course, it may also only have the second protrusions 32 without the first protrusions 31. In some other embodiments, positioning holes may also be formed in the scraping strip 3, and positioning protrusions inserted into the positioning holes are provided on the positioning frame 26 and the support frame 25.

[0065] In one embodiment, please refer to Figures 1 to 7 , in order to reduce the contact between the scraping strip bracket 2 and the ground, the scraping strip 3 extends along the length direction of the scraping strip bracket, and a wool mat 5 is provided on the scraping strip bracket 2 in the width direction. The wool mat 5 is on the scraping strip bracket 2 and is used to face the ground so as to prevent the scraping strip bracket 2 from contacting the ground. In one embodiment, wool mats 5 are provided at both ends of the scraping strip bracket 2. In one embodiment, the wool mat 5 is made of materials such as plastic and rubber.

[0066] In one embodiment of the scraping strip assembly of the cleaning robot, the scraping strip assembly of the cleaning robot is the scraping strip assembly described in any of the above embodiments, and will not be elaborated herein.

[0067] The above uses specific examples to elaborate on the present application, which is only used to help understand the present application and is not intended to limit the present application.
