Description

Technical Field

[0001] This application relates to the field of household appliance technology, and in particular to cleaning equipment. Background Technology

[0002] As people's living standards continue to improve, vacuum cleaners have gradually entered thousands of households, bringing great convenience to people's lives. A vacuum cleaner generally consists of a floor brush assembly for cleaning and a lever-shaped body for easy gripping and operation. The body can rotate relative to the floor brush assembly, allowing users to easily adjust the cleaning direction and angle. When the vacuum cleaner is stored, the body needs to be fixed relative to the floor brush assembly and prevent it from tipping over. In related technologies, to ensure the stability of the vacuum cleaner in its stored state, the connection between the floor brush assembly and the body is designed to be relatively complex, and their assembly is difficult. This results in a higher overall cost and more demanding installation requirements for the vacuum cleaner. Summary of the Invention

[0039] In some embodiments, when the body is in a stowed state, the angle θ between the first direction and the plane containing the surface of the floor brush assembly closest to the surface to be cleaned satisfies the following condition:

[0040] 0 < θ < 90°.

[0041] In some embodiments, when the body is in a stowed state, the angle θ between the first direction and the plane containing the surface of the floor brush assembly closest to the surface to be cleaned satisfies the following condition:

[0042] 70°≤θ<90°.

[0043] In some embodiments, the floor brush assembly includes:

[0044] The base plate is positioned on the side closest to the surface to be cleaned.

[0052] A movable member, one end of which abuts against the other end of the elastic member;

[0053] The elastic element is in a compressed state; when the connector rotates relative to the floor brush assembly to a preset position, the elastic element can drive the end of the moving part away from the elastic element to move along the fifth direction and extend out of the third opening.

[0054] In some embodiments, the bend connection assembly includes:

[0055] A bendable connector includes a first connecting portion and a second connecting portion that are arranged along the extension direction of the first rotation axis and connected to each other; the first connecting portion is rotatably connected to the floor brush assembly; the second connecting portion is partially annular in projection along a plane perpendicular to the first rotation axis; and the second connecting portion is constructed with a first snap-fit ​​semi-groove.

[0056] The mounting block is connected to the second connecting part; the mounting block is configured with a second snap-fit ​​half-groove.

[0065] In some embodiments, when the first rotating shaft and the second rotating shaft are held in the first relative position, the curved surface abuts against the groove wall of the limiting groove.

[0066] When the cleaning equipment is finished and needs to be stored, rotate the connector on the main body relative to the floor brush assembly to a preset position. This allows the joint on the floor brush assembly to engage with the mating part on the connector, thus storing the equipment. Because this cleaning equipment directly incorporates the joint on the floor brush assembly and the mating part on the connector on the main body, the engagement is achieved through the snap-fit ​​between the two. The entire assembly structure is relatively simple and easy for the user to operate; simply rotating the main body to a certain position is sufficient. This not only effectively reduces the overall cost of the cleaning equipment but also simplifies the assembly of the floor brush assembly and the main body. Attached Figure Description

[0098] Please see Figures 1-5 and combined Figure 6 and Figure 7 , Figure 1 This diagram shows the cleaning device body 1000 provided in some embodiments of this application in a stored state. Figure 2 It shows Figure 1 The diagram shows the cleaning equipment body 1000 in its second state. Figure 3 It shows Figure 1 The diagram shows the cleaning equipment body 1000 in the third state. Figure 4 It shows Figure 1 This diagram shows the connection between the connector 110 and the floor brush assembly 2000 in the cleaning device. Figure 5 It shows Figure 4 Exploded view of connector 110, floor brush assembly 2000 and bend connection assembly 4000 in the cleaning equipment shown. Figure 6 It shows Figure 4 The diagram shows the connection of the connector 110, the brush assembly 2000, the joint 3000, and the bend connection assembly 4000. Figure 7 It shows Figure 6 A magnified view of a portion at point A shown.

[0099] This application provides a cleaning device, which includes a body 1000, a floor brush assembly 2000, a curved pipe connecting assembly 4000, and a locking member. The curved pipe connecting assembly 4000 is connected between the body 1000 and the floor brush assembly 2000; and one end of the curved pipe connecting assembly 4000 is rotatably connected to the floor brush assembly 2000 about a first rotating shaft; specifically, the first rotating shaft is... Figure 3 The P-axis in the middle; the other end of the bend pipe connecting assembly 4000 is connected to the body 1000 and rotates around the second rotating axis; specifically, the second rotating axis is Figure 3 The N-axis in the middle; the locking member includes a joint portion 3000 and a mating portion 1 respectively disposed on the ground brush assembly 2000 and the body 1000; the first rotating shaft and the second rotating shaft have multiple relative positions perpendicular to each other, and the locking member keeps the first rotating shaft and the second rotating shaft in a fixed first relative position; wherein, when the first rotating shaft and the second rotating shaft are kept in a fixed first relative position, the joint portion 3000 and the mating portion 1 are engaged and connected so that the body 1000 is in a stored state.

[0100] When the cleaning equipment provided in this embodiment needs to be adjusted to a storage state after use, the body 1000 is rotated relative to the floor brush assembly 2000 via the bent pipe connecting assembly 4000, so that the joint portion 3000 constructed on the floor brush assembly 2000 can engage with the mating portion 1 on the body 1000, thereby placing the body 1000 in a storage state. Since this cleaning equipment directly sets the joint portion 3000 on the floor brush assembly 2000 and the mating portion 1 on the body 1000, the engagement between the two is achieved through the engaging engagement of the joint portion 3000 and the mating portion 1. The entire assembly structure is relatively simple and convenient for users to operate; they only need to rotate the body 1000 to a certain position. This not only effectively reduces the overall cost of the cleaning equipment but also reduces the assembly difficulty of the floor brush assembly 2000 and the body 1000.

[0101] It should be noted that the folded state of the 1000-series camera body is as follows: Figure 1 and Figure 4 The state shown is that the body 1000 is roughly perpendicular to the floor brush assembly 2000. The body 1000 is nearly upright and is not easy to tilt forward or backward relative to the floor brush assembly 2000. The body 1000 and the floor brush assembly 2000 are in a relatively stable state and are not easy to move relative to each other.

[0102] The cleaning device provided in this application embodiment achieves the storage and fixation of the body 1000 compared to the floor brush assembly 2000 by the snap-fit ​​engagement of the joint 3000 and the mating part 1. Therefore, compared with some structures such as metal springs, it has higher structural strength, better stability, and a simpler installation process.

[0103] It should be noted that the positions of the joint 3000 and the mating part 1 are not limited, and can be as follows: Figure 6 and Figure 7 The connecting part 3000 shown is provided on the floor brush assembly 2000, and the mating part 1 is provided on the body 1000. Of course, the connecting part 3000 can also be provided on the body 1000, and the mating part 1 can be provided on the floor brush assembly 2000.

[0104] The following is a detailed description of the structure of the cleaning equipment. Please refer to [link / reference]. Figures 8-21 , Figure 8 It shows Figure 4 The diagram shows the connection between the connector 110 and the bend connection assembly 4000 in the cleaning equipment. Figure 9 It shows Figure 8 A schematic diagram of connector 110 in the cleaning equipment shown. Figure 10 It shows Figure 9 The front view of connector 110 is shown. Figure 11 It shows Figure 10 A magnified view of point B shown. Figure 12 It shows Figure 9 Left view of connector 110 shown. Figure 13 It shows Figure 11 A magnified view of point C shown. Figure 14 It shows Figure 9 The bottom view of connector 110 shown. Figure 15 It shows Figure 14 The enlarged view of point D shown. Figure 16 It shows Figure 5 The diagram shows the top cover 230. Figure 17 It shows Figure 16 A magnified view of a portion at point E shown. Figure 18 It shows Figure 16 The diagram shown illustrates the installation of the joint 3000 at point E. Figure 19 It shows Figure 5 The diagram shows the connection between the bend connector 410 and the mounting block 420 in the bend connector assembly 4000.

[0105] Figure 20 It shows Figure 19 The diagram shows the bend connector 410. Figure 21 It shows Figure 19 A schematic diagram of the mounting block 420 is shown.

[0106] In some embodiments, one of the joint portion 3000 and the mating portion 1 is configured with a protrusion, and the other is configured with a groove that mates with the protrusion; one of the protrusion and the groove is configured with an elastic element that allows it to remain mated relative to the other.

[0107] The body 1000 is positioned relative to the floor brush assembly 2000 by the cooperation of protrusions and grooves. An elastic element is provided in one of the protrusions and grooves to allow it to maintain a fit with the other. This allows the user to easily engage or disengage the groove and protrusion by stepping on it or using other forceful methods, thanks to the elastic deformation of the elastic element.

[0108] In some embodiments, the joint 3000 is provided with a protruding pin; the mating part 1 is provided with a mating groove that matches the shape of the protruding pin; when the protruding pin and the mating groove are engaged, the angle between the floor brush assembly 2000 and the body 1000 relative to the first rotation axis and the second rotation axis is fixed, so that the body 1000 is in a retracted state.

[0109] By setting a protruding pin on the joint 3000 and setting a matching groove on the mating part 1, the angle of the floor brush assembly 2000 relative to the body 1000 is fixed through the cooperation of the matching groove and the protruding pin. The structure is simple and the processing and manufacturing are relatively convenient.

[0110] Please see Figure 10 and combined Figure 16 In some embodiments, the number of locking components is two sets; the two sets of locking components are symmetrically arranged on both sides of the first rotating shaft. Specifically, the first rotating shaft is... Figure 3 and Figure 8 The P-axis is shown.

[0111] By symmetrically arranging the locking components on both sides of the first rotating shaft, the two sets of connecting parts 3000 can be respectively set and snapped onto both sides of the first rotating shaft. This allows the latching mechanism to effectively utilize the gap between the bent tube connecting assembly 4000 and the floor brush assembly 2000, cleverly utilizing space and making the entire cleaning device more compact. Compared to placing the latching structure on the central axis of the floor brush assembly 2000, this arrangement does not increase the overall size of the floor brush assembly 2000, making it smaller and lighter. Furthermore, when the main body 1000 is in the folded state, the snapping of the two sets of connecting parts 3000 provides greater stability, preventing lateral swaying or tipping.

[0112] Please see Figure 5 and combined Figure 8 In some embodiments, the bend connection assembly 4000 includes a flexible hose 440, the two ends of which are connected to the body 1000 and the floor brush assembly 2000, respectively; the distance d1 between the two sets of locking members (see [reference]). Figure 10 ) and the diameter d2 of the flexible hose (see Figure 5The condition is satisfied: d2<d1≤2d2.

[0113] The flexible hose 440 of the bend connection assembly 4000 is used to connect to the body 1000 and the floor brush assembly 2000, thereby connecting the dust collection channel on the floor brush assembly 2000 with the dust cup channel on the body 1000 through the flexible hose 440, and thus transferring the dirt and debris collected by the floor brush assembly 2000.

[0114] By limiting the distance d1 between the two sets of locking components to be greater than the diameter d2 of the flexible hose 440 and less than twice the diameter d2 of the flexible hose, the latching mechanism will not interfere with the rotation of the flexible hose 440 when the flexible hose 440 rotates under the drive of the body 1000, making the rotation of the flexible hose 440 smoother.

[0115] In one specific embodiment, the distance d1 between the two sets of locking members is equal to 1.1 times the diameter d2 of the flexible hose 440. In another specific embodiment, the distance d1 between the two sets of locking members is equal to 2 times the diameter d2 of the flexible hose 440. In yet another specific embodiment, the distance d1 between the two sets of locking members is equal to 1.5 times the diameter d2 of the flexible hose 440.

[0116] Please see Figures 1-4 In some embodiments, the fuselage 1000 extends along a first direction; specifically, the first direction is... Figures 1-4 as well as Figures 6-7 The 'zz' direction; please refer to Figure 9 and Figure 10 The fuselage 1000 includes a connector 110 with a mating portion 1, the mating portion 1 having a first opening 2 along a second direction; the second direction is set at an angle to the first direction. Specifically, the second direction is... Figures 1-4 as well as Figure 9 The yy' direction in the middle.

[0117] By providing a connector 110 on the body 1000 and constructing a mating part 1 on the connector 110, when it is necessary to assemble the body 1000 with the floor brush assembly 2000, it is only necessary to assemble the body 1000 with the floor brush assembly 2000 through the connector 110. This not only facilitates the disassembly and assembly of the entire cleaning equipment, but also makes the transportation and installation process more convenient.

[0118] Please see Figures 6-15 In some embodiments, the connector 110 has a snap-fit ​​portion 10 extending along a third direction near the side of the floor brush assembly 2000; the third direction is angled to the first and second directions; specifically, the third direction is... Figures 1-4 as well as Figures 6-7In the xx' direction, the mating part 1 is constructed on the snap-fit ​​part 10. By constructing the snap-fit ​​part 10 on the connector 110 and the mating part 1 on the snap-fit ​​part 10, the processing and preparation of the mating part 1 is more convenient and simple.

[0119] Please see Figures 9-11 In some embodiments, the mating part 1 has a second opening 3 along a third direction, and the second opening 3 communicates with the first opening 2. Since the bent tube connecting assembly 4000 can rotate relative to the brush assembly 2000 about a first rotation axis, the mating part 1 and the joint part 3000 can be separated. By providing the second opening 3 in the mating part 1, the bent tube connecting assembly 4000 can easily slide into or out of the mating part 1 along the second opening 3 when rotating relative to the brush assembly 2000 about the first rotation axis, thereby making the angle adjustment of the body 1000 relative to the brush assembly 2000 more flexible.

[0120] Please see Figure 11 and Figure 13 In some embodiments, the groove wall of the mating part 1 includes a first sidewall 4, a second sidewall 5, and a third sidewall 6 connected sequentially to each other; wherein the first sidewall 4 and the third sidewall 6 extend along a third direction and are arranged opposite to each other along a first direction; the third direction is arranged at an angle to the first direction and the second direction; specifically, the first direction is... Figures 1-4 as well as Figures 6-7 The direction of zz' in the middle; the third direction is Figures 1-4 as well as Figures 6-7 The first sidewall 4, the second sidewall 5, and the third sidewall 6 are arranged together to form the mating part 1. This arrangement ensures that when the joint 3000 is accommodated within the mating part 1, the combined restraint of the first sidewall 4, the second sidewall 5, and the third sidewall 6 prevents the body 1000 from easily rotating around the second axis of rotation relative to the floor brush assembly 2000. Figure 3 , Figures 8-10 as well as Figure 19 The N-axis rotates, and the angle between the two does not easily change, thus enabling the 1000 body to maintain a more upright and stable state when stored, resulting in better stability.

[0121] Please see Figure 11 In some embodiments, along a first direction, the first sidewall 4 is located away from the floor brush assembly 2000; the third sidewall 6 is located near the floor brush assembly 2000; the length of the first sidewall 4 along a third direction is less than or equal to the length of the third sidewall 6 along a third direction; specifically, the third direction is... Figures 1-4 as well as Figures 6-7In the direction of xx'. By setting the length of the first sidewall 4 along the third direction to be less than or equal to the length of the third sidewall 6 along the third direction, the mating part 1 is longer on the side closer to the floor brush assembly 2000. As a result, when the joint part 3000 is engaged in the mating part 1, the third sidewall 6 can better limit the body 1000 from tilting downward and falling, thus improving safety.

[0122] Please see Figures 11-13 In some embodiments, a first guide slope 4a is constructed on the side of the first sidewall 4 away from the second sidewall 5; the first guide slope 4a is inclined upward along the second direction from the second opening 3 toward the second sidewall 5. By providing the first guide slope 4a, when the bent tube connecting assembly 4000 rotates relative to the ground brush assembly 2000 about the first rotation axis, and the connector 110 rotates relative to the bent tube connecting assembly 4000 about the second rotation axis, the joint 3000 can slide in or out along the first guide slope 4a during the process of sliding in or out of the mating part 1, and it is not easy to get stuck. The angle adjustment of the body 1000 is more sensitive and smooth than that of the ground brush assembly 2000, and the switching between the working state and the storage state of the body 1000 at any angle is also faster and more agile.

[0123] Please see Figure 11 In some embodiments, the bottom wall 7 of the mating part 1 along the second direction near the second opening 3 includes a parallel segment 7a and an inclined segment 7b connected to each other; the parallel segment 7a is parallel to the second side wall 5; the inclined segment 7b is inclined upward along the third direction from the second opening 3 toward the second side wall 5; the first guide slope 4a is connected to the inclined segment 7b. Since the length of the first side wall 4 along the third direction is less than or equal to the length of the third side wall 6 along the third direction, the bottom wall 7 of the mating part 1 along the second direction is also inclined at the second opening 3. In this application, by setting the bottom wall 7 of the mating part 1 along the second direction near the second opening 3 as a parallel segment 7a and an inclined segment 7b connected to each other, the bottom area of ​​the bottom wall 7 of the mating part 1 can be increased by the parallel segment 7a, so that when the joint 3000 is engaged in the mating part 1, it can have a larger contact area with the bottom wall 7 of the mating part 1, and the engagement is more stable, thereby making the fuselage 1000 more stable when in the position of the mating part 1. Figure 1 and Figure 4 The stability is better when the storage position is close to upright, as shown.

[0124] Please see Figures 11-14In some embodiments, the third sidewall 6 has a second guide slope 6a on the side away from the second sidewall 5; the second guide slope 6a is inclined upward along the second direction from the second opening 3 toward the second sidewall 5. By providing the second guide slope 6a, when the bent tube connecting assembly 4000 rotates relative to the ground brush assembly 2000 about the first rotation axis, and the connector 110 rotates relative to the bent tube connecting assembly 4000 about the second rotation axis, the joint 3000 can slide in or out along the second guide slope 6a during the sliding in or out of the mating part 1, and it is not easy to get stuck. The angle adjustment of the body 1000 is more sensitive and smooth than that of the ground brush assembly 2000, and the switching between the working state and the storage state of the body 1000 is also faster and more agile.

[0125] Please see Figure 11 and Figure 13 In some embodiments, the first sidewall 4 has a first inclined surface 4b on the side facing away from the groove of the mating part 1; the first inclined surface 4b is inclined downward along the second direction towards the third sidewall 6. When the fuselage 1000 needs to move from... Figure 2 or Figure 3 The state shown (joint 3000 separated from mating part 1) is switched to Figure 1 , Figure 4 and Figure 6 When the shown storage state (joint 3000 and mating part 1 are engaged) is reached, the bent tube connecting assembly 4000 needs to rotate relative to the brush assembly 2000 around the first rotation axis, and the connector 110 needs to rotate relative to the bent tube connecting assembly 4000 around the second rotation axis. During this rotation, there is a possibility that the joint 3000 needs to slide into or out of the mating part 1 from the side of the first side wall 4 away from the mating part 1. By providing the first inclined surface 4b, when the joint 3000 slides into or out of the mating part 1 from the side of the first side wall 4 away from the mating part 1, the first inclined surface 4b can guide the joint 3000 to slide in and out of the mating part 1.

[0126] Please see Figure 11 and Figures 13-14 In some embodiments, the third sidewall 6 has a second inclined surface 6b on the side facing away from the groove of the mating part 1; the second inclined surface 6b is inclined upward along the second direction towards the first sidewall 4. When the fuselage 1000 needs to move from... Figure 2 or Figure 3 The state shown (joint 3000 separated from mating part 1) is switched to Figure 1 , Figure 4 and Figure 6When the shown storage state (joint 3000 and mating part 1 are engaged) is reached, the bent tube connecting assembly 4000 needs to rotate relative to the brush assembly 2000 around the first rotation axis, and the connector 110 needs to rotate relative to the bent tube connecting assembly 4000 around the second rotation axis. During this rotation, there is a possibility that the joint 3000 needs to slide into or out of the mating part 1 from the side of the second side wall 5 away from the mating part 1. By providing the second inclined surface 6b, when the joint 3000 slides into or out of the mating part 1 from the side of the second side wall 5 away from the mating part 1, the guiding effect of the second inclined surface 6b can facilitate the sliding in and out of the joint 3000.

[0127] Please see Figure 12 and Figure 13 In some embodiments, the bottom wall 7 of the mating part 1 along the second direction, away from the groove of the mating part 1, is provided with at least one third inclined surface 7c; the third inclined surface 7c is inclined along the second direction toward the side of the floor brush assembly 2000. When the body 1000 needs to... Figure 2 or Figure 3 The state shown (joint 3000 separated from mating part 1) is switched to Figure 1 , Figure 4 and Figure 6 When the shown storage state (joint 3000 and mating part 1 are engaged) is reached, the bent tube connecting assembly 4000 needs to rotate relative to the brush assembly 2000 around the first rotation axis, and the connector 110 needs to rotate relative to the bent tube connecting assembly 4000 around the second rotation axis. During this rotation, there is a possibility that the joint 3000 needs to slide into or out of the mating part 1 from the side of the third side wall 6 away from the mating part 1. By providing the third inclined surface 7c, when the joint 3000 slides into or out of the mating part 1 from the side of the third side wall 6 away from the mating part 1, the guiding effect of the third inclined surface 7c facilitates the sliding in and out of the joint 3000.

[0128] This application provides different guide slopes and inclined surfaces on the side wall and bottom wall 7 of the mating part 1, so that when the mating part 3000 slides into or out of the mating part 1, the sliding process is smoother and less prone to jamming due to the guiding effect of the guide slopes and inclined surfaces. This makes the angle adjustment sensitivity of the body 1000 higher than that of the floor brush assembly 2000.

[0129] In some embodiments, when the body 1000 is in the stowed state, the center of gravity of the body 1000 is located within the projected area of ​​the floor brush assembly 2000 along the vertical plane. This arrangement makes the body 1000 less likely to tip over towards the surface opposite to the floor brush assembly 2000 when in the stowed state, thus improving the stability of the body 1000.

[0130] Please see Figure 6 In some embodiments, when the body 1000 is in the retracted state, the angle θ between the first direction and the plane containing the surface of the floor brush assembly 2000 closest to the surface to be cleaned satisfies the condition: 0 < θ < 90°. By setting θ within the range of greater than 0° and less than 90°, the angle between the body 1000 and the surface of the floor brush assembly 2000 closest to the surface to be cleaned is made acute when the body 1000 is in the retracted state, reducing the likelihood of the body 1000 tilting backward relative to the floor brush assembly 2000, thus preventing tipping. In one specific embodiment, θ is 10°. In another specific embodiment, θ is 85°, and in yet another specific embodiment, θ is 75°.

[0131] Please see Figure 6 In some embodiments, when the body 1000 is in the retracted state, the angle θ between the first direction and the plane containing the surface of the floor brush assembly 2000 closest to the surface to be cleaned satisfies the condition: 70° ≤ θ < 90°. By setting θ to a range greater than or equal to 70° and less than 90°, the angle between the body 1000 and the surface of the floor brush assembly 2000 closest to the surface to be cleaned is an acute angle when the body 1000 is in the retracted state, and this acute angle is close to 90°. This not only reduces the possibility of the body 1000 tilting backward relative to the floor brush assembly 2000 and tipping over, but also allows the body 1000 to be as vertical as possible, reducing its footprint and making it easy to store in a corner. In one specific embodiment, θ is 70°. In another specific embodiment, θ is 89°, and in yet another specific embodiment, θ is 80°.

[0132] Please see Figure 5 In some embodiments, the floor brush assembly 2000 includes a base plate 210, a roller brush 220, and a top cover 230. The base plate 210 is disposed near the surface to be cleaned; the roller brush 220 is rotatably connected to the base plate 210; the top cover 230 is disposed opposite to the base plate 210 along a fourth direction and connected to the base plate 210; specifically, the fourth direction is... Figures 1-4 as well as Figure 6 and Figure 7 The mm' direction; the joint 3000 is provided on the upper cover 230. When the surface to be cleaned needs to be cleaned, the roller brush 220 rotates relative to the base plate 210 and generates negative pressure through the motor inside the body 1000, so that the dirt is rolled away by the roller brush 220 and sucked into the dust cup assembly inside the body 1000 to complete the cleaning operation.

[0133] It should be noted that the fourth direction can be parallel or non-parallel to the first direction. When the body 1000 is rotated to a vertical position relative to the floor brush assembly 2000, the extension direction of the body 1000 is perpendicular to the floor brush assembly 2000, meaning the first and fourth directions are parallel. However, when the body 1000 is rotated to a non-vertical position relative to the floor brush assembly 2000, the extension direction of the body 1000, i.e., the first direction, is not parallel to the fourth direction.

[0134] Please see Figure 16 and combined Figure 17 and Figure 18 In some embodiments, the upper cover 230 has a mounting groove 23 on the side near the base plate 210, and the mounting groove 23 has a third opening 23a along a fifth direction; the fifth direction is perpendicular to the fourth direction; specifically, the fifth direction is... Figures 1-4 as well as Figure 6 and Figure 7 The joint 3000 is at least partially accommodated within the mounting groove 23 and is movable within the mounting groove 23 in the fifth direction. When the connector 110 rotates relative to the floor brush assembly 2000 to a preset position, the joint 3000 is configured to at least partially extend out of the third opening 23a and engage with the mating part 1. By providing a mounting groove 23 on the top cover 230 and a third opening 23a on the mounting groove 23, when the connector 110 of the body 1000 rotates relative to the floor brush assembly 2000 to a preset position, i.e., the retracted state, the joint 3000 can move in the fifth direction and extend out of the third opening 23a, thereby engaging with the mating part 1. The entire movement process is relatively simple and convenient.

[0135] Please see Figure 6 , Figure 7 as well as Figure 18In some embodiments, the joint 3000 includes an elastic member 310 and a movable member 320. One end of the elastic member 310 abuts against the bottom wall 7 of the mounting groove 23 on the side opposite to the third opening 23a; one end of the movable member 320 abuts against the other end of the elastic member 310; wherein the elastic member 310 is in a compressed state; when the connector 110 rotates relative to the brush assembly 2000 to a preset position, the elastic member 310 can drive the movable member 320 away from the end of the elastic member 310 to move in the fifth direction and extend out of the third opening 23a. Since the elastic element 310 is in a compressed state, when the connector 110 of the body 1000 rotates to the preset position, i.e., the retracted state, relative to the floor brush assembly 2000, the mating part 1 has a certain space so that the moving part 320 can move along the fifth direction. The moving part 320 can move along the fifth direction and extend out of the third opening 23a under the elastic force of the elastic element 310, so that the end of the moving part 320 away from the elastic element 310 is engaged in the mating part 1. When the moving part 320 is engaged in the mating part 1, the elastic element 310 can also continuously apply an elastic abutment force to the moving part 320, so that the end of the moving part 320 is not easy to separate from the mating part 1.

[0136] It should be noted that when the user needs to use this cleaning device and thus removes the main body 1000 from its stored state, the user steps on the floor brush assembly 2000 and pulls the main body 1000 away from the floor brush assembly 2000 to tilt the main body 1000 backward. During this process, the bottom wall below the mating part 1 will abut against the moving part 320, and the moving part 320 will be squeezed by the groove wall below the mating part 1, thereby briefly compressing the elastic part 310. The moving part 320 can then briefly leave the mating part 1 during the compression and deformation of the elastic part 310, thus releasing the limit. At this time, the user can rotate the main body 1000. The whole operation process is convenient and simple.

[0137] Please see Figure 19 and combined Figure 20 and Figure 21 In some embodiments, the bend connector assembly 4000 includes a bend connector 410 and a mounting block 420. The bend connector 410 includes a first connecting portion 411 and a second connecting portion 412 disposed along the extension direction of a first rotation axis and connected to each other; specifically, the extension direction of the first rotation axis is... Figure 8 , Figure 19 and Figure 20The first connecting part 411 is rotatably connected to the floor brush assembly 2000 in the direction of the P-axis; the second connecting part 412 is partially annular in shape along the projection of the plane perpendicular to the first rotating axis; the second connecting part 412 is constructed with a first snap-fit ​​half groove 4121; the mounting block 420 is connected to the second connecting part 412; the mounting block 420 is constructed with a second snap-fit ​​half groove 421; the first snap-fit ​​half groove 4121 and the second snap-fit ​​half groove 421 can be jointly arranged to form a snap-fit ​​groove 450; the connector 110 is constructed with a rotating protrusion 20; the rotating protrusion 20 is accommodated in the snap-fit ​​groove 450 and can rotate relative to the groove wall of the snap-fit ​​groove 450.

[0138] By setting the second connecting part 412 of the bent pipe connector 410 to be partially annular in projection along the extension direction of the first rotation axis, a certain installation space can be left here to facilitate the connection and rotation of the bent pipe connector 410 connected to the dust cup assembly of the body 1000 at the connector 110.

[0139] Furthermore, by providing a first snap-fit ​​half-groove 4121 on the second connecting part 412 and a second snap-fit ​​half-groove 421 on the mounting block 420, the first snap-fit ​​half-groove 4121 and the second snap-fit ​​half-groove 421 together form a snap-fit ​​groove 450, which cooperates with the rotating protrusion 20 on the connector 110, thereby realizing the rotation of the connector 110 relative to the bent pipe connecting assembly 4000 around the second rotating axis. This is relatively simple and convenient, and the structure is relatively compact, occupying less space.

[0140] Please see Figure 6 In some embodiments, the floor brush assembly 2000 further includes a viewing window 240 made of a transparent material. The viewing window 240 is mounted on the side of the roller brush 220 away from the base plate 210 and is fixedly connected to the base plate 210. The viewing window 240 is used to facilitate the user to view the rotation of the roller brush 220.

[0141] Please see Figure 6 In some embodiments, the floor brush assembly 2000 further includes an air inlet pipe 250, which is installed between the base plate 210 and the connector 110, and has an air intake channel. The bend pipe connection assembly 4000 includes a clip 430, which is installed between the bend pipe connector 410 and the air inlet pipe 250. The clip 430 is rotatably connected to the bend pipe connector 410 and snaps into the air inlet pipe 250. When the clip 430 rotates relative to the bend pipe connector 410, the bend pipe connection assembly 4000 can rotate relative to the air inlet pipe 250.

[0142] Please see Figure 7 and Figure 8In some embodiments, a limiting groove 8 is formed on the side of the snap-fit ​​portion 10 opposite to the mating portion 1; the mounting block 420 is at least partially accommodated within the limiting groove 8. By forming the limiting groove 8 directly on the side of the snap-fit ​​portion 10 opposite to the mating portion 1, and by allowing the mounting block 420 to be at least partially accommodated within the limiting groove 8, the structure of the entire cleaning device becomes more compact.

[0143] Please see Figure 7 and Figure 21 In some embodiments, along the second direction, the mounting block 420 has a curved surface 422 on the side near the limiting groove 8; the curved surface 422 is curved upward along the second direction from the side of the floor brush assembly 2000 toward the body 1000. By setting the curved surface 422, the mounting block 420, driven by the connector 110, rotates relative to the bent pipe connecting assembly 4000. Figure 8 When the N-axis rotates, the bottom wall 7 of the limiting groove 8 along the second direction will abut against the curved surface 422 of the mounting block 420 and rotate relative to it. Compared with the straight surface abutment, the curved surface abutment has less friction during the rotation process, which will also make the rotation of the mounting block 420 in the limiting groove 8 smoother.

[0144] Please see Figure 7 In some embodiments, when the first rotating shaft and the second rotating shaft are held in a first relative position, that is, when the connector 110 rotates relative to the floor brush assembly 2000 to a preset position, the curved surface 422 abuts against the groove wall of the limiting groove 8. When the body 1000 rotates relative to the floor brush assembly 2000 to a non-preset position, the mounting block 420 can rotate within the limiting groove 8 under the drive of the connector 110. And when the body 1000 rotates relative to the floor brush assembly 2000 to the preset position, that is... Figure 1 , Figure 4 and Figure 6 When in the retracted position as shown, the mounting block 420 can restrict the connector 110 from rotating relative to the bend connector assembly 4000. Figure 8 The rotation of the N-axis, which is the second rotation axis, limits the angle θ between the extension direction of the body 1000 (i.e., the first direction) and the plane of the surface of the floor brush assembly 2000 near the surface to be cleaned when the body 1000 is in the storage state to be greater than a preset value, thereby reducing the possibility of the body 1000 tilting forward and damaging the third side wall 6.

[0145] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0146] The embodiments described above are merely illustrative of several implementation methods of this application, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the patent application. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this application, and these all fall within the protection scope of this application. Therefore, the protection scope of this patent application should be determined by the appended claims.
