However, it is obvious to those skilled in the art that the technical solution provided by the utility model can be implemented without one or more of these details.

[0040] It should be noted that the terms used herein are only for describing specific embodiments and are not intended to limit exemplary embodiments according to the utility model.

[0041] Now, exemplary embodiments according to the present utility model will be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments can be implemented in a variety of different forms and should not be interpreted as being limited to the embodiments described herein. It should be understood that these embodiments are provided to make the disclosure of the present utility model thorough and complete, and to fully convey the concepts of these exemplary embodiments to those of ordinary skill in the art.

[0042] like Figures 1 to 14 As shown, an embodiment of the present utility model provides a connecting device 100 and a cleaning device 200 , wherein the connecting device 100 is applied to the cleaning device 200 .

[0043] Furthermore, if Figure 1 and Figure 6 As shown, the cleaning device 200 includes but is not limited to: a machine body 210, a cleaning system, a driving system, etc. The functional elements constituting the above-mentioned systems in the cleaning device 200 are integratedly arranged in the machine body 210. It can be understood that the cleaning device 200 can be a self-moving cleaning device 200, and the above-mentioned systems coordinate with each other so that the cleaning device 200 can move autonomously to achieve the cleaning function. The self-moving cleaning device 200 is a device that automatically performs cleaning operations in a certain area to be cleaned without user operation.

[0044] Among them, Figure 1 , Figure 6 , Fig.14As shown, the cleaning system may include a wet cleaning system, such as the cleaning device 200 may be a mopping robot. Further, the wet cleaning system includes a cleaning component 220, a water supply mechanism, a liquid storage tank, etc., wherein the cleaning component 220 is connected to the machine body 210 and may be arranged below the liquid storage tank, and the cleaning liquid inside the liquid storage tank is transmitted to the cleaning component 220 through the water supply mechanism, so that the cleaning component 220 performs wet cleaning on the surface to be cleaned, so as to realize the mopping function. Specifically, the cleaning component 220 may be a disc brush assembly, a drag disc assembly, or other components.

[0045] Specifically, the wet cleaning system may include a cleaning component 220, which may also be Figure 1 and Figure 7 As shown, two cleaning components 220 are included.

[0046] like Figure 2 , Figure 3 , Figure 7 , Figure 8 , Fig.14 As shown, an embodiment of the first aspect of the utility model provides a connecting device 100, which is configured to detachably connect a cleaning component 220 to a machine body 210, and the connecting device 100 includes a first coupling portion and a second coupling portion that cooperate with each other, and the first coupling portion and the second coupling portion are respectively arranged on the cleaning component 220 and the machine body 210; wherein the connecting device 100 realizes the switching of locking and unlocking of the first coupling portion and the second coupling portion by pressing.

[0047] The connecting device 100 provided in the embodiment of the utility model can detachably connect the cleaning component 220 to the machine body 210, thereby making it easier to assemble and disassemble the cleaning component 220 from the machine body 210, and the cleaning component 220 can be removed from the machine body 210 for maintenance or cleaning, thereby improving the maintenance efficiency of the cleaning component 220 and the convenience of the cleaning operation, thereby improving user satisfaction.

[0048] The connection device 100 includes a first coupling portion and a second coupling portion respectively arranged on the cleaning component 220 and the machine body 210. The connection device 100 realizes locking and unlocking of the first coupling portion and the second coupling portion by pressing. That is to say, when the connection device 100 is in a locked or unlocked state, a pressing force is required to bring the first coupling portion and the second coupling portion closer to each other in order to switch the state of the connection device 100. When the connection device 100 is in a locked state and the cleaning component 220 is connected to the machine body 210, if the cleaning component 220 is heavy after being soaked or the bumping force is large, the first coupling portion and the second coupling portion will have a tendency to move away from each other, which is opposite to the direction of the pressing force on the connection device 100. As a result, the cleaning component 220 has a greater weight or a greater bumping force after being soaked, so that the locking state of the connecting device 100 can be more secure, so that the cleaning component 220 can be firmly fixed on the machine body 210. Compared with the cleaning component fixed to the machine body by adsorption in the related art, the phenomenon of the cleaning component 220 falling off caused by the failure of the adsorption of the adsorbent, the heavy weight of the disc brush assembly after being soaked, or the bumping force being greater than the adsorption force is avoided, which greatly improves the reliability of the fixing of the cleaning component 220 to the machine body 210, and is convenient for disassembly and assembly and not easy to fall off, thereby ensuring the reliability of the cleaning equipment 200 and improving the user experience.

[0049] Among them, the connecting device 100 realizes the switching of locking and unlocking of the first coupling part and the second coupling part by pressing, and the pressing operation can be realized by applying pressing force to the first coupling part to move the first coupling part toward the second coupling part, or by applying pressing force to the second coupling part to move the second coupling part toward the first coupling part; or, the pressing operation can be realized by applying pressing force to the first coupling part and the second coupling part at the same time to move the first coupling part and the second coupling part toward each other.

[0050] Specifically, when the separated cleaning component 220 and the machine body 210 need to be fixed to each other, the connecting device 100 is in an unlocked state, that is, the first coupling portion and the second coupling portion are separated from each other, and the first coupling portion and the second coupling portion are pressed to bring the first coupling portion and the second coupling portion closer to each other and then the first coupling portion and the second coupling portion are locked, so that the cleaning component 220 can be fixed to the machine body 210. Figure 1 , Figure 2 , Figure 3 and Fig.14 shown.

[0051] When it is necessary to separate the cleaning component 220 from the machine body 210, the cleaning component 220 and the machine body 210 can be separated by pressing the first coupling part and / or the second coupling part to bring the first coupling part and the second coupling part closer to each other and then unlocking the first coupling part and the second coupling part. Figure 7 , Figure 8 and Fig. 9 shown.

[0052] That is to say, the locked and unlocked states of the first coupling part and the second coupling part can be switched by pressing, which is simple to operate, easy to use, ergonomic, and suitable for popularization and application.

[0053] like Figure 2 , Figure 3 , Figure 7 and Figure 8 As shown, in some possible embodiments provided by the present invention, the first coupling portion and the second coupling portion are a lock buckle 110 and a lock tongue 120 respectively.

[0054] Among them, the locking tongue 120 is movably arranged, and the lock buckle 110 is fixedly arranged. The lock buckle 110 can be locked or released by the movement of the locking tongue 120, thereby realizing the locking and unlocking operation of the connecting device 100. The operation is simple and can ensure the reliability and stability of the locking state, thereby improving the reliability of the connection between the cleaning component 220 and the machine body 210.

[0055] Further, the lock buckle 110 may be disposed on the cleaning component 220 , and the lock tongue 120 may be movably disposed on the machine body 210 , or the lock buckle 110 may be disposed on the cleaning device 200 , and the lock tongue 120 may be movably disposed on the cleaning component 220 .

[0056] like Figure 3 , Figure 8 , Fig.12 and Fig.13As shown, in some possible embodiments provided by the present utility model, the connecting device 100 further includes: a fixed seat 130, a first elastic member 140 and a movable member. The fixed seat 130 is connected to the machine body 210, and the fixed seat 130 is provided with a receiving cavity with an opening 131 facing the cleaning component 220, the first elastic member 140 and the movable member are arranged in the receiving cavity, the locking tongue 120 is connected to the first elastic member 140, and can move along the opening 131 toward or away from the cleaning component 220; the movable member is connected to the locking tongue 120, and a limiting structure 160 is provided between the movable member and the cavity wall of the receiving cavity to limit the movement trajectory of the movable member; wherein the first elastic member 140 is used to cooperate with the limiting structure 160, so as to drive the locking tongue 120 to move to the first position or the second position after pressing the locking tongue 120, the locking tongue 120 at the first position is in a locked state, and the locking tongue 120 at the second position is in an unlocked state.

[0057] In this embodiment, Figure 2 , Figure 3 , Figure 7 , Figure 8 and Fig.14 As shown, the lock tongue 120 is arranged on the machine body 210, and the lock buckle 110 is arranged on the machine body 210. The lock tongue 120 is movably mounted on the fixing seat 130 through the first elastic member 140 and the movable push rod 152, and then the fixing seat 130 is connected to the machine body 210, so that the lock tongue 120 can be mounted on the machine body 210 and can be movable relative to the machine body 210, which is simple to operate and convenient to install.

[0058] like Figure 8 , Fig. 9 and Fig.10 As shown, when the connecting device 100 is in the unlocked state, the lock buckle 110 and the lock tongue 120 are separated, that is, the cleaning component 220 and the machine body 210 are separated, and the lock buckle 110 is moved in the direction close to the lock tongue 120 to press the lock tongue 120 (which can be regarded as the first press). If the user holds the cleaning component 220 and moves it in the direction close to the machine body 210, the pressing force overcomes the elastic force of the first elastic member 140 to compress the first elastic member 140 to deform, so that the lock tongue 120 moves along the opening 131 toward the inside of the fixed seat 130. At the same time, the movable part will move according to the preset trajectory under the action of the lock tongue 120 and the limiting structure 160. When the pressing force is released, such as after the hand is released, the first elastic member 140 restores the deformation and drives the lock tongue 120 to move along the opening 131 toward the outside of the fixed seat 130. Under the action of the limiting structure 160, the lock tongue 120 moves to the first position. At this time, Figure 2 , Figure 3 , Figure 4 and Figure 5 , Fig.13As shown, the locking tongue 120 locks the lock buckle 110 to realize the locking operation of the connecting device 100, so that the cleaning component 220 can be reliably and stably connected to the machine body 210. In this state, if the cleaning component 220 is heavy after being soaked, or the bumping force is greater than the adsorption force, due to the limiting effect of the limiting structure 160, it can still ensure that the locking tongue 120 firmly and stably locks the lock buckle 110, thereby ensuring that the cleaning component 220 is not easy to fall off, and ensuring the reliability of the cleaning device 200.

[0059] like Figure 2 , Figure 3 , Figure 4 and Figure 5 , Fig.13 As shown, on the basis that the cleaning component 220 is connected to the machine body 210 through the connecting device 100, that is, when the locking tongue 120 locks the locking buckle 110, the locking tongue 120 is moved again in the direction close to the locking tongue 120 by the locking buckle 110 (which can be regarded as the second pressing). If the user holds the cleaning component 220 and moves it in the direction close to the machine body 210, the pressing force will again overcome the elastic force of the first elastic member 140 to compress the first elastic member 140 to deform, so that the locking tongue 120 moves along the opening 131 toward the inside of the fixed seat 130. At the same time, the movable part will move according to the preset trajectory under the action of the locking tongue 120 and the limiting structure 160. When the pressing force is released, such as after the hand is released, the first elastic member 140 recovers its deformation and drives the locking tongue 120 to move along the opening 131 toward the outside of the fixed seat 130. Under the action of the limiting structure 160, the locking tongue 120 moves to the second position. Figure 8 , Fig. 9 and Fig.10 As shown, at this time, the locking tongue 120 loosens the lock buckle 110 to achieve the unlocking operation of the connecting device 100, so that the cleaning component 220 can be conveniently separated from the machine body 210.

[0060] Among them, Figure 5 and Fig.10 As shown, the locking tongue 120 in the first position is closer to the interior of the fixing base 130 than the locking tongue 120 in the second position. Figure 5 As shown, most or all of the lock tongue 120 in the first position is located in the opening 131. Thus, under the limiting effect of the inner wall of the opening 131, the opening 131 of the lock tongue 120 has a smaller angle, and the lock buckle 110 can be reliably locked to achieve the buckle locking operation. Fig.10 As shown, most or all of the lock tongue 120 in the second position is located outside the opening 131, so that the inner wall of the opening 131 has little or no limiting effect on the lock tongue 120, so that the angle of the opening 131 of the lock tongue 120 is larger, which can loosen the lock buckle 110, and then the lock buckle 110 can move to achieve the unlocking operation.

[0061] Furthermore, the first elastic member 140 and the movable member are installed in the accommodating cavity of the fixing seat 130 , so that the fixing seat 130 has a certain protective effect on the first elastic member 140 and the movable member, thereby extending the service life of the first elastic member 140 and the movable member.

[0062] The fixing seat 130 and the machine body 210 may be detachably connected, thereby facilitating the maintenance and replacement of the first elastic member 140, the movable member, and the locking tongue 120, and is conducive to improving the maintenance efficiency of the connecting device 100. Specifically, the fixing seat 130 and the machine body 210 may be detachably connected by at least one of a screw connection, a plug-in structure, a clamping structure, and a mortise and tenon structure. It is understandable that the fixing seat 130 and the machine body 210 may also be detachably connected by other structures, or, in some examples, the fixing seat 130 may also be fixedly connected to the machine body 210 by welding, an adhesive, or the like.

[0063] The first elastic member 140 may be a spring, a tension spring or other elastic structures. Taking the first elastic member 140 as a spring as an example, one end of the spring may be connected to the fixing seat 130, and the other end may be connected to the locking tongue 120, such as one end of the spring is fixed to the side of the fixing seat 130 away from the opening 131, and the other end of the spring is connected to an end of the locking tongue 120 located inside the fixing seat 130.

[0064] Among them, the movable part is connected to the lock tongue 120, and a limiting structure 160 is arranged between the movable part and the fixed seat 130. Therefore, under the action of the limiting structure 160, the moving trajectory of the movable part can be limited, so that the movable part drives the lock tongue 120 to move within a certain range, and the movable part and the lock tongue 120 will not interfere with each other, ensuring the smoothness of the relative movement of the movable part and the lock tongue 120, so as to ensure that the lock tongue 120 can reliably and accurately move to the first position and the second position, thereby improving the accuracy of locking and unlocking the connecting device 100.

[0065] Specifically, the movable member is connected to the lock tongue 120 , and the movable member and the lock tongue 120 may be fixedly connected, hinged, or abutted.

[0066] like Figure 5 , Figure 6 , Fig.10 and Fig.11As shown, in some possible embodiments provided by the present invention, the limiting structure 160 includes a first guide groove 161 provided on the cavity wall of the accommodating cavity, and a convex portion 162 provided on or connected to the movable member, and the convex portion 162 is located in the first guide groove 161 and can move along the first guide groove 161. Therefore, through the cooperation between the first guide groove 161 and the convex portion 162 provided on or connected to the movable member, the moving track of the movable member can be limited, and then the moving track of the lock tongue 120 connected to the member can be limited, so that the first guide groove 161 and the convex portion 162 can reliably, stably and accurately reset the pressed lock tongue 120 to the first position or the second position under the cooperation of the first elastic member 140.

[0067] The convex portion 162 may be connected to the movable part, such as the convex portion 162 and the movable part are split structures, and the convex portion 162 and the movable part are fixedly connected or detachably connected. Alternatively, the convex portion 162 may be arranged on the movable part, such as the convex portion 162 and the movable part may be an integrated structure. Thus, the requirements of different structures of the movable part can be met.

[0068] Among them, Figure 6 and Fig.10 As shown, the first guide groove 161 is an irregular shape, and the groove wall and / or groove bottom of the first guide groove 161 are provided with a guide surface 1611 to guide the protrusion 162 to run in the first guide groove 161 according to a preset track, and the protrusion 162 provided on or connected to the movable part can be kept at the M position or the N position of the guide groove 161 under the action of the first elastic member 140, and correspondingly, the locking tongue 120 is in the first position or the second position. Specifically, as Figure 6 As shown in FIG. 1 , when the protrusion 162 is located at the M position of the first guide groove 161, the locking tongue 120 is in the first position. Fig.11 As shown, the lock tongue 120 locks the lock buckle 110. When the protrusion 162 is located at the N position of the first guide groove 161, the lock tongue 120 is in the second position, and the lock tongue 120 is released. The moving track of the protrusion 162 in the first guide groove 161 is shown in FIG. Figure 6 and Fig.11 As shown by the dotted arrow in .

[0069] like Figure 3 , Figure 5 , Figure 6 , Figure 8 , Fig.10 and Fig.11As shown, in some possible embodiments provided by the present invention, the movable member includes a second elastic member 151, a mounting groove 121 is provided on the side of the lock tongue 120 facing the first guide groove 161, the second elastic member 151 and the protrusion 162 are located in the mounting groove 121, the protrusion 162 is located between the second elastic member 151 and the first guide groove 161, and the second elastic member 151 is used to apply a force close to the bottom of the first guide groove 161 to the protrusion 162, so that under the action of the second elastic member 151, the protrusion 162 can reliably and stably move along a preset track in the first guide groove 161. At the same time, the second elastic member 151 plays a role in connecting the lock tongue 120 and the protrusion 162, so that the two can be linked. Specifically, the second elastic member 151 can be a spring, a spring, or other elastic structures.

[0070] Specifically, pressing the lock tongue 120 causes the lock tongue 120 to move, and the second elastic member 151 can drive the protrusion 162 to move in the first guide groove 161. After the pressing force is released, under the action of the first elastic member 140, the lock tongue 120 moves and causes the protrusion 162 to move in the first guide groove 161, so as to limit the movement trajectory of the lock tongue 120.
