Description

Technical Field

[0001] This invention relates to the field of intelligent cleaning technology, and more specifically, to a cleaning robot that is easy to install with a mop. Background Technology

[0002] Cleaning robots with mopping functions have a mop attached to the bottom of their bodies for wiping and cleaning floors. The mop is usually fixed in place by a cleaning disc, for example, by using Velcro to attach the mop to the cleaning disc.

[0003] When installing the mop, you first need to determine the relative position between the mop and the cleaning disc. Then, you need to press the mop onto the cleaning disc. This requires the user to concentrate on aligning the mop with the cleaning disc during installation. However, it is easy for the mop to be installed crookedly, requiring the user to tear off the mop and re-align it. Summary of the Invention

[0004] The purpose of this invention is to provide a cleaning robot that facilitates mop installation, enabling rapid positioning and installation of the mop without the need for repeated alignment.

[0005] To achieve the above objectives, the present invention provides a cleaning robot for easy mop installation, comprising a body with a rotating shaft at the bottom of the body, the rotating shaft being connected to a cleaning turntable, the top surface of the cleaning turntable being bonded by an adhesive structure, the bottom surface of the cleaning turntable being provided with a first positioning structure, and the top surface of the mop being provided with a second positioning structure, a horizontal sliding gap for the mop being provided between the first positioning structure and the second positioning structure, the horizontal sliding gap allowing the mop to slide relative to the cleaning turntable while the cleaning turntable is rotating, thereby increasing the adhesive force of the adhesive structure.

[0006] Optionally, in one embodiment, one of the first positioning structure and the second positioning structure is a positioning protrusion and the other is a positioning groove, and the horizontal sliding gap is the gap between the positioning protrusion and the groove wall of the positioning groove.

[0007] Optionally, in one embodiment, the positioning protrusion is movably engaged in the positioning groove, allowing the mop to rotate relative to the cleaning turntable, and the positioning groove is provided with a stop structure for preventing the movement of the positioning element.

[0008] Optionally, in one embodiment, the stop structure is a partition rib arranged in the positioning groove, the partition rib dividing the positioning groove into several arc-shaped grooves, and the positioning protrusion correspondingly engaging with each arc-shaped groove.

[0009] Optionally, in an embodiment, a rotating block connected with the rotating shaft is arranged at the top center of the cleaning turntable, and the rotating block is in floating connection with the cleaning turntable.

[0010] Optionally, in an embodiment, a buckle structure is arranged between the cleaning turntable and the rotating block, and an elastic member is abutted between the cleaning turntable and the rotating block.

[0011] Optionally, in an embodiment, a mounting cavity opening upward for mounting the rotating block is arranged at the top of the cleaning turntable, the rotating block can move up and down in the mounting cavity, and a recess accommodating the elastic member is arranged on one side of the rotating block relative to the mounting cavity.

[0012] Optionally, in an embodiment, the diameter of the mop is greater than the diameter of the cleaning turntable, so that the peripheral part of the mop not abutting against the cleaning turntable can adapt to the uneven ground.

[0013] Optionally, in an embodiment, when the cleaning robot is in a working state, the part of the mop beyond the cleaning turntable abuts against the bottom surface of the body.

[0014] Optionally, in an embodiment, the mop comprises a mop body and a hem, and the hem has outwardly expanding cleaning mop strips located outside the cleaning turntable.

[0015] Compared with the prior art, the present application has the following advantages:

[0016] In the cleaning robot, the first positioning structure and the second positioning structure cooperate to realize the positioning of the mop and the cleaning turntable. The adhesive structure is used to adhere the mop to the bottom of the cleaning turntable, thereby realizing the installation and fixation of the mop. The horizontal sliding gap between the first positioning structure and the second positioning structure realizes the relative sliding of the mop relative to the cleaning turntable. On the one hand, when the mop is installed, the mop can be pressed back and forth at the adhesive structure to make the adhesive structure more firmly adhere the mop. On the other hand, when the cleaning turntable rotates, i.e. when the cleaning robot is used for mopping, the mop and the cleaning turntable slide relative to each other in the horizontal direction when the body moves, which can increase the adhesion of the adhesive structure and reduce the probability of the mop falling during mopping.

[0017] In the present application, the positioning protrusion is positioned in the positioning groove, thereby realizing the coaxial positioning of the mop and the cleaning turntable, avoiding the eccentric installation of the mop and the cleaning turntable, and affecting the mopping effect. At the same time, the positioning protrusion can move in the positioning groove, so that the mop can rotate relative to the cleaning turntable, which is convenient for the positioning adjustment of the mop during installation. In addition, the stop structure in the positioning groove is used to limit the maximum rotation angle of the mop, thereby avoiding the damage of the adhesive structure due to the too large rotation angle of the mop.

[0018] The cleaning turntable is connected with the rotating shaft through the adapter block, so that the cleaning turntable can float relative to the bottom of the machine body to adapt to uneven ground and achieve the effect of shock absorption.

[0019] The diameter of the cleaning robot mop is greater than that of the cleaning turntable, so that the part of the mop that does not abut against the cleaning turntable can adapt to uneven ground. When the cleaning robot cleans on uneven ground, the part of the mop that exceeds the edge of the cleaning turntable can be attached to the convex part of the ground. Since there is no abutting support of the cleaning turntable, the edge part of the mop will deform with the change of the convexity of the ground, and the cleaning dead angle formed by the convexity will be wiped and cleaned, thereby improving the efficiency of the whole house cleaning.

[0030] In order to make the objects, technical solutions and advantages of the present application clearer, the following further describes the present application with reference to the embodiments and drawings. Obviously, the described embodiments are only some, but not all of the embodiments of the present application. Based on the described embodiments, all other embodiments obtained by those of ordinary skill in the art without creative effort belong to the scope of the present application.

[0031] Unless otherwise defined, technical terms or scientific terms used in the present application shall have the ordinary meanings understood by those of ordinary skill in the art to which the present application pertains. The present application uses "comprise" or "include" and similar words in the sense of "comprising" or "including", meaning that the elements or objects appearing before the word encompass the elements or objects listed after the word and equivalents thereof, without excluding other elements or objects. "Connected" or "connected" and similar words are not limited to physical or mechanical connections, but can include electrical connections, whether direct or indirect. "Up", "down", "left", "right" and the like are only used to represent relative positional relationships, which may change accordingly when the absolute positions of the described objects change.

[0032] Referring to Figure 1 and Figure 2 , the cleaning robot provided by the embodiment includes a body 100, the body 100 is provided with a traveling wheel assembly and a surface cleaning assembly. The traveling wheel assembly includes drive wheels 200 arranged at both sides of the bottom of the body 100, and the surface cleaning assembly includes a mop 300 and a roller brush 400 arranged at the bottom of the body 100.

[0033] The body 100 is provided with a drive wheel motor, a mop motor and a roller brush motor (not shown in the figure), which are used to drive the drive wheels 200, the mop 300 and the roller brush 400 to rotate, respectively.

[0034] The mop 300 is installed at the bottom of the body 100 through a cleaning turntable 301. Referring to Figure 3 and Figure 4 , the bottom of the body 100 is provided with a vertical downward rotating shaft 101, the rotating shaft 101 is connected to the output end of the mop motor, the rotating shaft 101 is connected with the cleaning turntable 301, and the bottom surface of the cleaning turntable 301 is bonded with the top surface of the mop 300 through a bonding structure such as a magic tape structure.

[0035] The bottom surface of the cleaning turntable 301 is provided with a first positioning structure, the top surface of the mop 300 is provided with a second positioning structure, and the first positioning structure and the second positioning structure are provided with a horizontal sliding gap of the mop 300. The horizontal sliding gap allows the mop 300 to slide relative to the cleaning turntable in the rotating state of the cleaning turntable 301, so as to increase the bonding force of the bonding structure.

[0036] The first positioning structure and the second positioning structure cooperate to realize the positioning of the mop 300 and the cleaning turntable 301. The adhesive structure is used to adhere the mop 300 to the bottom of the cleaning turntable 301, so as to realize the installation and fixation of the mop 300. Through the horizontal sliding gap between the first positioning structure and the second positioning structure, the mop 300 can slide relative to the cleaning turntable 301. On the one hand, when the mop 300 is installed, the mop 300 can be pressed back and forth at the adhesive structure to make the adhesive structure more firmly adhere the mop 300. On the other hand, when the cleaning turntable 301 rotates, that is, when the cleaning robot is mopping, the mop 300 and the cleaning turntable 301 slide relative to each other in the horizontal direction when the robot 100 moves, which can increase the adhesion of the adhesive structure and reduce the probability of the mop 300 falling during mopping.

[0037] One of the first positioning structure and the second positioning structure is a positioning protrusion, and the other is a positioning groove. The horizontal sliding gap is the gap between the groove wall of the positioning protrusion and the positioning groove. The positioning protrusion can be arranged on the top surface of the mop 300, and the positioning groove can be arranged on the bottom surface of the cleaning turntable 301. Alternatively, the positioning protrusion can be arranged on the top surface of the mop 300, and the positioning groove can be arranged on the bottom surface of the cleaning turntable 301. The horizontal sliding gap is less than 2 cm to avoid the sliding distance of the mop 300 being too large to exceed the bearing range of the adhesive structure.

[0038] Referring to FIGS. 6 to Figure 9 For example, the positioning protrusion 302 is arranged on the top surface of the mop 300, and the positioning groove 3011 is arranged on the bottom surface of the cleaning turntable 301. The positioning protrusion 302 and the positioning groove 3011 cooperate to position and install the mop 300 on the bottom surface of the cleaning turntable 301.

[0039] Further, the positioning protrusion can be movably arranged in the positioning groove, so that the mop 300 can rotate relative to the cleaning turntable 301.

[0040] When the mop 300 is installed, first, the positioning protrusion 302 is positioned in the positioning groove 3011 to realize the coaxial positioning between the mop 300 and the cleaning turntable 301. Then, the adhesive structure is used to adhere the mop 300 to the bottom of the cleaning turntable 301 to realize the installation of the mop 300. Compared with the conventional direct adhesive fixation of the mop, the positioning and installation method of the present embodiment aligns the positioning protrusion 302 with the positioning groove 3011, avoids the eccentric installation of the mop and the cleaning turntable, and affects the mopping effect. Even if the mop is not aligned with the installation position at the beginning, the positioning protrusion can be moved into the positioning groove, and after positioning, the adhesive structure is pressed to fix the mop. Even without focusing the eyes on the positioning, the entire installation process of the mop is more smooth, and the positioning is more accurate and fast.

[0041] The positioning protrusion and the positioning recess can include a corresponding pair, which are respectively arranged at the centers of the mop 300 and the cleaning turntable 301. In this case, the positioning protrusion can be a column, and the positioning recess can be a circular or square cavity. The column can rotate in the circular or square cavity, so that the mop 300 rotates relative to the cleaning turntable 301.

[0042] The positioning protrusion and the positioning recess can also include a corresponding plurality of groups, which are respectively arranged in a circular manner on the mop 300 and the cleaning turntable 301, with the centers of the mop 300 and the cleaning turntable 301 as the centers of the circles. In this case, the positioning protrusion can be a column or a tooth, and the positioning recess can be an arc. One column or tooth can correspond to one arc-shaped positioning recess, or multiple columns or teeth can correspond to one arc-shaped positioning recess, or all the columns or teeth can correspond to one annular positioning recess. The column or tooth can move in the positioning recess, so that the mop 300 rotates relative to the cleaning turntable 301.

[0043] Further, the arc-shaped or annular positioning recess can be divided by a stop structure arranged in the positioning recess. The stop structure is used to stop the movement range of the positioning protrusion in the positioning recess, so as to avoid damage to the bonding structure due to excessive rotation angle of the mop. In this embodiment, the stop structure is a separation rib 3012 arranged in the positioning recess 3011. The separation rib 3012 divides the positioning recess 3011 into a plurality of arc-shaped grooves. As shown in Figure 9 , the positioning protrusion 302 corresponds to and is matched into one arc-shaped groove.

[0044] The positioning protrusion and the positioning recess are arranged in a relatively movable matching mode, so that the mop 300 has more alignment positions during installation, and the installation can be completed more quickly. Further, a chamfer can be arranged at the edge of the positioning recess 3011, so as to facilitate the entry of the positioning protrusion.

[0045] Referring to Figure 6 and Figure 7 , the positioning protrusion 302 can be arranged on the top surface of the mop 300 through a base body 303. The base body 303 can be a plastic disc or a plastic ring fixed on the top surface of the mop 300. The positioning protrusion 302 and the base body 303 can be integrally formed. In this way, the stability of the positioning protrusion 302 is improved.

[0046] Further, referring to Figure 5 , the top center of the cleaning turntable 301 is provided with a conversion block 102 connected with the rotating shaft 101. The conversion block 102 is floatingly connected with the cleaning turntable 301. In this way, the cleaning turntable 301 can float relative to the rotating shaft 101 to adapt to uneven ground, so as to achieve the effect of shock absorption.

[0047] The buckle structure is arranged between the cleaning turntable 301 and the adapter block 102, and the elastic member abuts between the cleaning turntable 301 and the adapter block 102. The floating reset between the cleaning turntable 301 and the adapter block 102 is realized by the elastic member, and the reset locking between the cleaning turntable 301 and the adapter block 102 is realized by the buckle structure.

[0048] Further, referring to Figure 8 , the top of the cleaning turntable 301 is provided with a mounting cavity 3013 which is open upward and used for mounting the adapter block 102, the adapter block 102 can move up and down in the mounting cavity 3013, and one side of the adapter block 102 relative to the mounting cavity 3013 is provided with a recess cavity (not shown in the figure) for accommodating the elastic member.

[0049] The elastic member of the embodiment is a compression spring 304. One end of the compression spring 304 abuts and cooperates with the side wall of the recess cavity of the adapter block 102, and the other end is placed in the mounting cavity 3013. Referring to Figure 10 , the edge of the adapter block 102 is provided with a limiting flange 1021 for preventing the adapter block 102 from rotating in the mounting cavity 3013.

[0050] Further, the buckle structure can include a flange arranged on one of the adapter block 102 and the mounting cavity 3013, and a clamping hook arranged on the other. For example, in the embodiment, an outward flange 1022 is arranged at the edge of the adapter block 102, and an inward clamping hook 3014 is arranged on the inner wall of the mounting cavity 3013. When the adapter block 102 and the cleaning turntable 301 are mounted, the adapter block 102 is directly pressed into the mounting cavity 3013, so that the clamping hook 3014 in the mounting cavity 3013 hooks the flange 1022 in the adapter block 102. If the adapter block 102 and the cleaning turntable 301 are to be separated, the clamping hook 3014 in the mounting cavity 3013 is simply pried outward, so that the flange 1022 is separated from the clamping hook 3014, and at the same time, under the elastic force of the compression spring 304, the adapter block 102 is quickly ejected from the mounting cavity 3013.

[0051] Further, a waist-shaped hole 1023 is arranged on the adapter block 102, which is used for interference fit with the rotating shaft 101 to realize circumferential positioning. At the same time, a screw hole (not shown in the figure) is arranged in the waist-shaped hole 1023, and the rotating shaft 101 is fixedly connected in the axial direction by the screw 103, as shown in Figure 4 . At the same time, a through hole 3015 is arranged at the center of the cleaning turntable 301, and when mounted, the adapter block 102 is first matched with the cleaning turntable 301, then the waist-shaped hole 1023 of the adapter block 102 is aligned with and matched with the rotating shaft 101, and finally the screw is connected with the rotating shaft 101 by passing through the through hole 3015 of the cleaning turntable 301 and the screw hole of the adapter block 102.

[0052] Further, the diameter of the mop 300 is larger than the diameter of the cleaning disc 301, so that the peripheral portion of the mop 300 not abutting against the cleaning disc 301 can adapt to the uneven ground. When the cleaning robot cleans the uneven ground, the portion of the mop 300 beyond the edge of the cleaning disc 301 can be in contact with the convex portion of the ground. Since there is no abutting support of the cleaning disc 301, the edge portion of the mop 300 can be deformed along with the convexity of the ground, and the edge portion of the mop 300 can mop and clean the cleaning dead angle formed by the convexity, thereby improving the cleaning efficiency of the whole house.

[0053] When the cleaning robot is in the working state, the portion of the mop 300 beyond the cleaning disc 301 is in abutment with the bottom surface of the body 100. The portion of the mop 300 beyond the cleaning disc 301 is divided into two parts, one part is located at the bottom of the body 100, and the other part is beyond the edge of the body 100. The portion of the mop 300 beyond the edge of the body 100 can be used to adapt to the uneven ground, and the portion of the mop 300 located at the bottom of the body 100 is in abutment with the bottom surface of the body 100, so as to reduce the hair from entering and winding around the shaft 101 through the gap between the mop 300 and the cleaning disc 301.

[0054] The mop 300 comprises a mop main body and a hem (not shown in the figure), and the hem has outwardly expanding cleaning mop strips 305 located outside the cleaning disc 301. The cleaning mop strips 305 are in the shape of strips, and can be uniformly directed to the outside of the cleaning disc 301, or can be arranged in disorder on the hem. The cleaning mop strips 305 can extend into the cleaning dead angle, such as the gap of the corner, to clean the cleaning dead angle.
