[0039] Unless otherwise defined, all technical terms used in the embodiments of the present application have the same meanings as those generally understood by those of ordinary skill in the art. Some technical terms appearing in the embodiments of the present application are explained below.

[0040] In order to make the technical solutions and advantages of the present application more clear, the implementation methods of the present application will be further described in detail below with reference to the accompanying drawings.

[0041] An embodiment of the present application provides a cleaning device, including a floor brush assembly 1 and a water tank assembly 2.

[0042] The floor brush assembly 1 includes a floor brush body 11 and a connecting portion 12 connected to the floor brush body 11. Figure 1 As shown, the connection portion 12 is located at one side in the width direction of the floor brush body 11. Exemplarily, the floor brush assembly 1 is used to perform cleaning operations such as vacuuming and sweeping.

[0043] The water tank assembly 2 includes a shell and a buckle mechanism 23 . The shell is recessed with a receiving groove 211 . The buckle mechanism 23 includes a movable buckle 231 . The movable buckle 231 can be retracted and extended from the groove wall of the receiving groove 211 .

[0044] Exemplarily, the shell includes a first shell 21 and a second shell 22, which are connected to each other and enclosed to form a storage space, and the storage space is used to hold cleaning media such as water and detergent. A cleaning mechanism 24 such as a mop or sponge can be connected to the bottom of the second shell 22 to facilitate cleaning operations such as mopping the floor.

[0045] The first shell 21 is located above the second shell 22 . The first shell 21 is recessed with a receiving groove 211 . The receiving groove 211 is used to accommodate the connecting portion 12 , so that the floor brush assembly 1 and the water tank assembly 2 are connected in the width direction through the connecting portion 12 and the receiving groove 211 .

[0046] Among them, the size and shape of the accommodating groove 211 are adapted to the size and shape of the connecting part 12 to limit the movement range of the connecting part 12 in the accommodating groove 211 and prevent the connecting part 12 from moving and affecting the connection stability of the floor brush assembly 1 and the water tank assembly 2.

[0047] The floor brush assembly 1 and the water tank assembly 2 can be detachably connected through the connecting portion 12 and the receiving groove 211. When the floor brush assembly 1 and the water tank assembly 2 are connected, the floor brush assembly 1 and the water tank assembly 2 are distributed along the width direction, and the floor brush assembly 1 is located in front of the water tank assembly 2 to realize the front suction and rear mopping function of the cleaning device. When the floor brush assembly 1 and the water tank assembly 2 are separated, the cleaning device can perform sweeping or vacuuming operations only through the floor brush assembly 1, or can perform mopping operations only through the water tank assembly 2.

[0048] The buckle mechanism 23 has an extended state and a retracted state, and can be extended or retracted relative to the side wall of the receiving groove 211. Figure 7 As shown, the first housing 21 is provided with a through hole 212. In the extended state, as shown in FIG. Fig.10 As shown, the movable buckle 231 extends through the through hole 212 to the side where the receiving groove 211 is located; in the retracted state, the movable buckle 231 retracts into the receiving space through the through hole 212.

[0049] When the connecting portion 12 is located in the receiving groove 211 and the movable buckle 231 extends relative to the groove wall of the receiving groove 211, the movable buckle 231 limits the connecting portion 12; when the movable buckle 231 retracts relative to the groove wall of the receiving groove 211, the connecting portion 12 can be separated from the receiving groove 211.

[0050] The connecting portion 12 can move closer to or farther from the receiving groove 211 and push the active buckle 231 to switch the active buckle 231 from the extended state to the retracted state.

[0051] Specifically, the connecting portion 12 can achieve the connection or separation between the floor brush assembly 1 and the water tank assembly 2 by approaching or moving away from the receiving groove 211 in the height direction. The user can connect or separate the floor brush assembly 1 from the water tank assembly 2 by simply pressing down or lifting up the floor brush assembly 1; the connecting portion 12 can also achieve the connection or separation between the floor brush assembly 1 and the water tank assembly 2 by approaching or moving away from the receiving groove 211 in the width direction. The user can connect or separate the floor brush assembly 1 from the water tank assembly 2 by pushing or pulling it horizontally.

[0052] The buckle mechanism 23 can switch between an extended state and a retracted state. When the external force applied to the buckle mechanism 23 is 0, the buckle mechanism 23 is in an extended state. When the buckle mechanism 23 is in a retracted state due to an external force, if the external force is removed, the buckle mechanism 23 returns to the extended state.

[0053] When the connecting portion 12 is located in the receiving groove 211 and the movable buckle 231 extends out relative to the groove wall of the receiving groove 211, the movable buckle 231 limits the connecting portion 12 at least in the height direction; when the movable buckle 231 retracts relative to the groove wall of the receiving groove 211, the connecting portion 12 can be separated from the receiving groove 211.

[0054] Alternatively, if Figure 2 As shown, when the connecting portion 12 is located in the receiving groove 211 and the buckle mechanism 23 is in an extended state, the movable buckle 231 is located on the side of the connecting portion 12 away from the receiving space (i.e., above the connecting portion 12), and the movable buckle 231 can abut against the upper surface of the connecting portion 12 and limit the connecting portion 12 in the height direction, thereby preventing the connecting portion 12 from falling out of the receiving groove 211.

[0055] Optionally, a snap-fit ​​groove is provided on the side wall of the connecting part 12. When the connecting part 12 is located in the accommodating groove 211 and the snap-fit ​​mechanism 23 is in an extended state, the movable snap-fit ​​231 is inserted into the snap-fit ​​groove, which can not only limit the connecting part 12 in the height direction, but also in the width direction or the length direction.

[0056] In an optional embodiment, if Fig.10As shown, the movable buckle 231 extends along the length direction of the cleaning device to extend or retract along the length direction of the cleaning device. In another optional embodiment, as Fig. 9 As shown, the active buckle 231 extends along the width direction of the cleaning device to extend or retract along the width direction of the cleaning device. In another optional embodiment, the buckle mechanism 23 is multiple, and the active buckles 231 of a part of the buckle mechanisms 23 extend along the length direction of the cleaning device, and the active buckles 231 of another part of the buckle mechanisms 23 extend along the width direction of the cleaning device.

[0057] The cleaning device provided in the embodiment of the present application, when it is necessary to connect the floor brush assembly 1 and the water tank assembly 2, the connecting part 12 is moved close to the receiving groove 211 and the movable buckle 231 is pushed to retract the movable buckle 231 relative to the groove wall of the receiving groove 211, so that the connecting part 12 is smoothly inserted into the receiving groove 211, and then the movable buckle 231 is extended relative to the groove wall of the receiving groove 211 to limit the connecting part 12 and prevent the connecting part 12 from escaping from the receiving groove 211, thereby realizing a stable connection between the floor brush assembly 1 and the water tank assembly 2; when it is necessary to separate the floor brush assembly 1 and the water tank assembly 2, the connecting part 12 of the floor brush assembly 1 is moved away from the receiving groove 211 and the movable buckle 231 is pushed to retract the movable buckle 231 relative to the groove wall of the receiving groove 211, thereby taking the connecting part 12 out of the receiving groove 211, separating the connecting part 12 from the receiving groove 211, and realizing the separation of the floor brush assembly 1 and the water tank assembly 2. This design saves the cost of installing the magnetic connection assembly, is less prone to damage, and improves the connection stability and reliability of the floor brush assembly and the water tank assembly.

[0058] Furthermore, the buckle mechanism 23 includes a reset structure, which can be a structure with automatic reset function such as an elastic ball, a spring, a rocker rod, a counterweight structure, an electromagnetic structure, etc. The reset structure is used to drive the active buckle 231 to return from the retracted state to the extended state, so that the active buckle 231 remains in the extended state when not subjected to external force.

[0059] Specifically, the reset structure is a reset elastic member 232, which is respectively connected to the housing and the movable buckle 231. The reset elastic member 232 is a compression spring and can be deformed along its own length direction. When the reset elastic member 232 is compressed, it has a tendency to resist compression, thereby driving the movable buckle 231 to switch from a retracted state to an extended state.

[0060] like Figure 3 and Figure 4 As shown, a cross rib structure 231 c is protruded from one end of the movable buckle 231 , and the resetting elastic member 232 is sleeved on the outside of the cross rib structure 231 c to achieve connection with the movable buckle 231 .

[0061] In a further embodiment, the end of the movable buckle 231 away from the reset elastic member 232 has a first inclined surface 231a and a second inclined surface 231b, both of which are inclined in the depth direction of the receiving groove 211, and the first inclined surface 231a and the second inclined surface 231b are gradually separated from the end away from the reset elastic member 232 to the end close to the reset elastic member 232. The depth direction of the receiving groove 211 is the height direction of the cleaning device.

[0062] like Figure 3 As shown, the first inclined surface 231 a is located above the second inclined surface 231 b , and an angle is formed between the first inclined surface 231 a and the second inclined surface 231 b .

[0063] By providing the first inclined surface 231a and the second inclined surface 231b, it is convenient to guide the connection part 12 to push the active buckle 231 along the inclined surface, so that the buckle mechanism 23 can be smoothly switched from the extended state to the retracted state. For example, when the floor brush assembly 1 and the water tank assembly 2 need to be connected, the connection part 12 is moved close to the receiving groove 211 and the active buckle 231 is pushed back along the first inclined surface 231a; when the floor brush assembly 1 and the water tank assembly 2 need to be separated, the connection part 12 is moved away from the receiving groove 211 and the active buckle 231 is pushed back along the second inclined surface 231b.

[0064] In a specific embodiment, the housing is formed with a mounting cavity 214 , and the mounting cavity 214 is used to install the buckle mechanism 23 . The mounting cavity 214 is located at one side of the accommodating groove 211 .

[0065] Exemplarily, the first shell 21 includes a plurality of vertical walls 213 connected in sequence, and the plurality of vertical walls 213 surround a mounting cavity 214 . The mounting cavity 214 is used to mount the buckle mechanism 23 , and the mounting cavity 214 is located at one side of the accommodating groove 211 .

[0066] like Figure 5 As shown, multiple vertical walls 213 are located on one side of the first shell 21 close to the second shell 22. The multiple vertical walls 213 and the inner wall of the first shell 21 enclose a rectangular space for accommodating the reset elastic member 232 and the movable buckle 231. The movable buckle 231 can extend from the installation cavity 214 to the side where the accommodating groove 211 is located or retract into the installation cavity 214.

[0067] The installation cavity 214 may be located at one side of the receiving groove 211 along the length direction of the cleaning device, or may be located at one side of the receiving groove 211 along the width direction of the cleaning device, and may be specifically arranged according to the movement direction of the movable buckle 231 .

[0068] In a further embodiment, a guide structure 215 is formed in the installation cavity 214 , and the guide structure 215 is used to limit the movable buckle 231 to extend or retract along a straight line.

[0069] Exemplarily, the guide structure 215 may be a structure such as a slide rail, a slide groove, a bump, etc. for limiting the direction of movement, thereby ensuring that the movable buckle 231 moves smoothly along a straight line.

[0070] In a specific embodiment, the guide structure 215 protrudes along the height direction in the installation cavity 214, and the guide structure 215 and the second shell 22 are respectively located on both sides of the movable buckle 231 in the height direction of the cleaning device. The guide structure 215 and the second shell 22 can limit the movable buckle 231 in the height direction of the cleaning device.

[0071] like Figure 6 As shown, the guide structure 215 is convex on one side surface of the first shell 21 toward the second shell 22, and the guide structure 215 extends along the length direction of the cleaning device. The movable buckle 231 is located between the second shell 22 and the guide structure 215. The guide structure 215 can ensure that the movable buckle 231 moves along the length direction of the cleaning device, and at the same time, it can cooperate with the second shell 22 to limit the movable buckle 231 in the height direction of the cleaning device to prevent the movable buckle 231 from being deflected or misplaced in the height direction of the cleaning device.

[0072] The housing further includes a buckle limiting structure 216 , which is a convex strip arranged at intervals on the two side walls of the installation cavity 214 .

[0073] The buckle limiting structure 216 is disposed on the first housing 21 and is located in the mounting cavity 214. Figure 6 As shown, the buckle limiting structure 216 is arranged on two vertical walls 213 that are relatively arranged along the width direction of the cleaning device, and the buckle limiting structure 216 extends along the height direction of the cleaning device. The buckle limiting structure 216 can limit the active buckle 231 on both sides of the active buckle 231 along the width direction of the cleaning device to prevent the active buckle 231 from being skewed or misplaced in the width direction of the cleaning device.

[0074] Based on any of the above embodiments, the accommodating groove 211 has a bottom groove wall 211d, a front groove wall 211c and two side groove walls 211b, the front groove wall 211c and the two side groove walls 211b are connected to the bottom groove wall 211d, the front groove wall 211c is respectively connected to the two side groove walls 211b and is located between the two side groove walls 211b, and the movable buckle 231 can be retracted from the front groove wall 211c or the side groove wall 211b.

[0075] For example, Fig.10 As shown, the movable buckle 231 can extend relative to the side groove wall 211b.

[0076] For example, Fig. 9As shown, the movable buckle 231 of the buckle mechanism 23 can extend relative to the front slot wall 211c.

[0077] Furthermore, there are multiple buckle mechanisms 23, wherein two buckle mechanisms 23 are respectively located at two side groove walls 211b and can be extended or retracted relative to the side groove walls 211b.

[0078] Specifically, Figure 8 As shown, the two snap mechanisms 23 are symmetrically distributed along the length direction of the cleaning device, wherein one snap mechanism 23 can extend or retract relative to the first side groove wall 211b, and the other snap mechanism 23 can extend or retract relative to the second side groove wall 211b, which is beneficial to fully limit the connecting portion 12 in the accommodating groove 211 in the length direction of the cleaning device.

[0079] The first housing 21 further includes a limiting portion 217 protruding from the bottom groove wall 211 d , and the limiting portion 217 is disposed opposite to the front groove wall 211 c .

[0080] like Figure 7 The limiting portion 217 is located at one end of the first shell 21 in the width direction, and the limiting portion 217 and the front groove wall 211c are spaced apart in the width direction, thereby limiting the connecting portion 12 in the width direction of the cleaning device, thereby preventing the floor brush assembly 1 and the water tank assembly 2 from being separated when the cleaning device performs a cleaning operation in the width direction of the cleaning device.

[0081] Optionally, the accommodating groove 211 has a rear groove wall arranged opposite to the front groove wall 211 c , and the connection portion 12 can be limited in the width direction of the cleaning device only by the accommodating groove 211 .

[0082] In one embodiment, the side groove wall 211 b and / or the front groove wall 211 c are provided with convex ribs 211 a , and the convex ribs 211 a are used to abut against the connecting portion 12 .

[0083] Exemplarily, the extending direction of the rib 211a is parallel to the connecting direction of the connecting portion 12 and the receiving groove 211, that is, parallel to the distribution direction of the first inclined surface 231a and the second inclined surface 231b. For example, when the first inclined surface 231a and the second inclined surface 231b are arranged opposite to each other along the height direction of the cleaning device, so that the connecting portion 12 is connected to or separated from the receiving groove 211 along the height direction, as shown in FIG. Figure 7 As shown, the rib 211 a extends in the height direction, which reduces the friction between the rib 211 a and the connecting portion 12 , making it easier to connect or separate the connecting portion 12 and the receiving groove 211 .

[0084] Specifically, there are multiple ribs 211a, which are spaced apart on the side groove wall 211b and / or the front groove wall 211c. By providing the ribs 211a, the friction area between the connecting portion 12 and the receiving groove 211 is reduced, making it easier to connect or separate the connecting portion 12 from the receiving groove 211.

[0085] An embodiment of the present application also provides a vacuum cleaner, comprising a handle and a cleaning device provided in any of the above embodiments, wherein the handle is connected to a floor brush assembly 1 of the cleaning device, and the handle facilitates hand-held operation by a user.
