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. Vacuum cleaners generally consist 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 adjust the cleaning direction and angle. However, when the angle of the body relative to the floor brush assembly changes, the flexible hose in the curved connecting assembly between the body and the brush assembly is prone to twisting. This not only makes the flexible hose easily damaged and shortens its lifespan, but also causes users to experience a feeling of sticking or jamming during operation, resulting in a poor user experience.

[0073] When using the aforementioned cleaning equipment, if it is necessary to adjust the angle between the main body and the floor brush assembly, this can be achieved by rotating the main body relative to the bend connector assembly, or by rotating the bend connector assembly relative to the floor brush assembly. This allows for relatively flexible adjustment of the angle between the main body and the floor brush assembly. During this process, because the flexible hose rotates relative to the air inlet pipe of the floor brush assembly under the influence of the bend connector, it effectively reduces the twisting of the flexible hose along its own length. This reduces the deformation direction of the flexible hose, minimizes damage to the flexible hose, extends its service life, and reduces resistance during use, resulting in a smoother operation and a better user experience.

[0113] To make the above-mentioned objectives, features, and advantages of this application more apparent and understandable, the specific embodiments of this application are described in detail below with reference to the accompanying drawings. Many specific details are set forth in the following description to provide a thorough understanding of this application. However, this application can be implemented in many other ways different from those described herein, and those skilled in the art can make similar modifications without departing from the spirit of this application. Therefore, this application is not limited to the specific embodiments disclosed below.

[0114] In the description of this application, it should be understood that if terms such as "center", "longitudinal", "lateral", "length", "width", "thickness", "upper", "lower", "front", "rear", "left", "right", "vertical", "horizontal", "top", "bottom", "inner", "outer", "clockwise", "counterclockwise", "axial", "radial", "circumferential" appear, these terms indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0115] Furthermore, where the terms "first" and "second" appear, these terms are for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this application, where the term "multiple" appears, "multiple" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0116] In this application, unless otherwise expressly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components, unless otherwise expressly limited. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0117] In this application, unless otherwise expressly specified and limited, the use of descriptions such as "above" or "below" the second feature indicates that the first and second features are in direct contact or indirect contact via an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. Similarly, "below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0118] It should be noted that if an element is referred to as being "fixed to" or "set on" another element, it can be directly on the other element or there may be an intervening element. If an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intervening element. If so, the terms "vertical," "horizontal," "upper," "lower," "left," "right," and similar expressions used in this application are for illustrative purposes only and do not represent the only possible implementation.

[0119] See Figures 1-4 , Figure 1 A schematic diagram of a cleaning device provided in some embodiments of this application in a first posture is shown. Figure 2 It shows Figure 1 The diagram shows the cleaning equipment in its second position. Figure 3 It shows Figure 1 The diagram shows the cleaning equipment in its third position. Figure 4 It shows Figure 1 The diagram shows the cleaning equipment in its fourth position.

[0120] One embodiment of this application provides a cleaning device including a body 1000, a floor brush assembly 2000, and a curved pipe connection assembly 4000. The body 1000 includes a vacuum source; the floor brush assembly 2000 has an air inlet pipe 270 connected to the vacuum source; the curved pipe connection assembly 4000 includes a curved pipe connector 410 and a flexible hose 440; one end of the curved pipe connector 410 is rotatably connected to the body 1000, and the other end of the curved pipe connector 410 is rotatably connected to the floor brush assembly 2000; the flexible hose 440 is rotatably connected to the air inlet pipe 270 through the curved pipe connector 410.

[0121] When the cleaning equipment provided in this application embodiment needs to be adjusted relative to the floor brush assembly 2000, the angle between the body 1000 and the floor brush assembly 2000 can be adjusted flexibly by rotating the angle between the body 1000 and the bend connector 4000, or by rotating the bend connector 4000 relative to the floor brush assembly 2000. During this process, because the flexible hose 440 rotates relative to the air inlet pipe 270 of the floor brush assembly 2000 under the influence of the bend connector 410, the twisting of the flexible hose 440 along its length is effectively reduced. This reduces the deformation direction of the flexible hose 440, minimizes damage to the flexible hose 440, extends its service life, reduces resistance during use, and makes the process smoother, resulting in a better user experience.

[0122] Please see Figures 1-4 In some embodiments, the body 1000 includes a connector 110, and the bent pipe connection assembly 4000 is connected to the body 1000 through the connector 110.

[0124] Please see Figure 25 and Figure 29 In some embodiments, the cleaning device further includes a dust cup module 6000 and a motor 7000. The dust cup module is mounted on the body 1000 and has a receiving cavity (6130) and a first air inlet and a first air outlet communicating with the receiving cavity 6130; the motor 7000 is electrically connected to the dust cup module 6000 and the first air outlet is communicating with the air inlet of the motor; the floor brush assembly 2000 is detachably connected to the dust cup module 6000 and has an air outlet duct 280 connected to the first air inlet.

[0125] The air outlet duct 280 is connected to the first air inlet of the dust cup module 6000, and the motor 7000 is connected to the first air outlet of the dust cup module 6000. This allows the motor 7000 to create a negative pressure in the receiving cavity 6130 and the air outlet duct 280 when it is turned on. This causes the floor brush assembly 2000 to suck the mixture of garbage and airflow into the air outlet duct 280, and then into the receiving cavity 6130 through the first air inlet for garbage filtration and collection. The airflow is then discharged into the external environment from the first exhaust port.

[0126] Please see Figure 25 In some embodiments, the dust cup module 6000 has an extension tube 6200 communicating with the receiving cavity 6130, the extension tube 6200 having a first air inlet, and the air outlet duct 280 communicating with the first air inlet.

[0127] The extension pipe 6200 is located at the bottom of the dust cup module 6000. The bottom opening of the extension pipe 6200 forms a first air inlet. The extension pipe 6200 extends downward into the air outlet duct 280, thereby connecting the air outlet duct 280 with the first air inlet. When cleaning is performed by this cleaning device, the mixture of debris and airflow can be sucked in from the air inlet of the floor brush assembly, flow through the air outlet duct 540, and then flow into the extension pipe 6200 through the first air inlet, and then into the receiving cavity 6130 connected to the extension pipe 6200.

[0128] Please see Figure 25In some embodiments, the dust cup module 6000 includes a dust cup body 6100, a side tube 6300, and a transition tube 6400. The dust cup body 6100 has a receiving cavity 6130. An extension tube 6200 extends outward from the end of the dust cup body 6100 away from the body 1000. The side tube 6300 is located on one side of the dust cup body 6100 along a second direction. The transition tube 6400 extends obliquely from the extension tube 6200 to the side tube 6300. The extension tube 6200, the transition tube 6400, the side tube 6300, and the receiving cavity 6130 are sequentially connected. The second direction is set at an angle to the first direction. Specifically, the second direction is... Figure 20 The yy' direction; the first direction is Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 18 as well as Figure 19 The direction of ww'.

[0129] Specifically, the dust cup body 6100 includes an upper cup portion 6110 and a lower cup portion 6120 arranged sequentially along a third direction and internally connected, with their inner cavities connected to form a receiving cavity 6130 for storing waste; specifically, the third direction is... Figure 25 The body 1000 is connected to the upper cup 6110, and the floor brush assembly 2000 is installed in the lower cup 6120. The extension tube 6200 extends downward from the lower cup 6120. In use, the side tube 6300 is located on the side of the dust cup body 6100 near the area to be cleaned. Both the side tube 6300 and the extension tube 6200 extend in a third direction. The extension direction of the transition tube 6400 connecting the two forms an angle with the third direction. The transition tube 6400 extends upward from the extension tube 6200 to the side tube 6300. A notch is formed on the side of the side tube 6300 near the upper cup 6110 to communicate with the receiving cavity 6130. A silicone baffle is installed at this notch position. When the motor 7000 is not turned on, the silicone baffle covers the notch position to separate the receiving cavity 6130 and the inner cavity of the side tube 6300. When the motor 7000 is turned on, the silicone baffle flips up under the suction force, so that the opening is no longer blocked. The mixture of garbage and airflow flows into the extension pipe 6200, then flows through the transition pipe 6400 and the side pipe 6300 in sequence, and flows into the receiving cavity 6130 from the opening.

[0130] Please see Figure 25In some embodiments, a filter 6500 is provided within the receiving cavity 6130. The mixture of waste and airflow is filtered and separated by the filter 6500. The waste falls downwards under gravity and accumulates within the receiving cavity 6130. The airflow flows through the filter 6500, rising upwards from its interior and entering the inner cavity of the body 1000. A HEPA filter 6600 is installed within the inner cavity of the body 1000. The airflow entering the inner cavity of the body 1000 flows from the outside to the inside of the HEPA filter 6600, thus completing the filtration. After filtration, dust particles and other contaminants fall back into the receiving cavity 6130 under gravity, while the clean airflow continues to rise from the inside of the HEPA filter 6600 and enters the air inlet of the motor 7000. The body 1000 also has an air outlet. The airflow exiting from the air outlet of the motor 7000 is deflected, flowing downwards and outwards before finally being discharged into the external environment. Because the airflow passes through filters 6500 and HEPA 6600 before flowing into the motor 7000, the dust particles in the airflow discharged to the external environment are reduced, thus ensuring its cleanliness as much as possible.

[0131] Please see Figures 1-3 as well as Figure 25 and Figure 29 In some embodiments, the cleaning device also includes a battery pack 600 disposed at one end of the motor 7000, and wires are embedded in the body 1000 and the dust cup module 6000 to realize the electrical connection between the battery pack 600 and the motor 7000 and the dust cup module 6000.

[0132] Please see Figures 1-3 as well as Figure 25 and Figure 29 In some embodiments, the cleaning device also includes a handle 9000, which is mounted on the body 1000 for easy gripping by the user when operating the cleaning device.

[0133] Please see Figure 6 and Figures 7-9 In some embodiments, the cleaning device further includes a retaining ring 5000; the retaining ring 5000 is disposed between the curved pipe connecting assembly 4000 and the floor brush assembly 2000; and the retaining ring 5000 is fixedly connected to one of the curved pipe connecting assembly 4000 and the floor brush assembly 2000, while the other is rotatably connected. By fixing the retaining ring 5000 to one of the curved pipe connecting assembly 4000 and the floor brush assembly 2000, while rotatably connecting the other, the rotatable connection between the two is made simpler and more convenient.

[0134] In some embodiments, the retaining ring 5000 is fixedly connected to the floor brush assembly 2000, and the retaining ring 5000 is rotatably connected to the curved pipe connecting assembly 4000. When the retaining ring 5000 rotates relative to the curved pipe connecting assembly 4000, the body 1000 can rotate relative to the floor brush assembly 2000, thereby realizing the angle adjustment and posture change of the body 1000 relative to the floor brush assembly 2000.

[0135] Please see Figures 1-6 In some embodiments, the floor brush assembly 2000 further includes a front wheel assembly 210 and a rear wheel assembly 220 spaced apart along a first direction. Specifically, the first direction is... Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 18 as well as Figure 19 The direction of the bend in the ww' direction; wherein, the bend connecting assembly 4000 can rotate relative to the brush assembly 2000 about the first rotating axis; the first rotating axis is not coaxial with the rotating axis of the rear wheel assembly 220; specifically, the first rotating axis is Figure 3 and Figure 4 The P-axis in the middle; the rotation axis of the rear wheel assembly 220 is... Figure 3 and Figure 4 The o-axis in the middle.

[0136] When the above-mentioned cleaning equipment is in use, if it is necessary to adjust the angle between the body 1000 and the floor brush assembly 2000, the bent tube connecting assembly 4000 rotates around the first rotating axis relative to the floor brush assembly 2000. Since the first rotating axis is not on the same axis as the rotation axis of the rear wheel assembly 220, when the bent tube connecting assembly 4000 rotates around the first rotating axis, the rear wheel assembly 220 on the floor brush assembly 2000 will not rotate synchronously. This ensures that the rear wheel assembly 220 can always be in contact with the surface to be cleaned and is not prone to tilting relative to the surface to be cleaned. Consequently, the contact area between the floor brush assembly 2000 and the surface to be cleaned does not change significantly, the force on the floor brush assembly 2000 is relatively balanced, it is not prone to tipping over, the cleaning effect is good, and the user's control and operation of the cleaning equipment is relatively simple, resulting in a better user experience.

[0137] When the cleaning equipment provided in this application is in use, since the bent pipe connecting assembly 4000 rotates around the first rotating axis relative to the floor brush assembly 2000, and the first rotating axis is not coaxial with the rotating axis of the rear wheel assembly 220, the rear wheel of the rear wheel assembly 220 can be a conventional wheel similar to the front wheel assembly 210 set on the floor brush assembly 2000, without the need to use irregularly shaped wheels such as spherical wheels. Therefore, the rear wheel of the rear wheel assembly 220 can be a wheel with a larger diameter. When the entire cleaning equipment is in use and the machine body 1000 needs to be in a near-upright storage state, the rear wheel of the rear wheel assembly 220 can provide a relatively stable support force, thereby effectively meeting the standing requirements of the machine body 1000.

[0138] Please see Figure 6 and Figures 7-9 In some embodiments, the projection of the retaining ring 5000 onto a plane extending perpendicular to the first rotation axis is partially annular. This arrangement makes it easier to slip the retaining ring 5000 onto the bend connector assembly 4000.

[0139] Please see Figure 10 In some embodiments, the intake pipe 270 near the bend connector 4000 has an annular first snap-fit ​​groove 271 circumferentially formed on its side, and the first snap-fit ​​groove 271 has at least one snap-fit ​​through hole 271a on its radially concentric side. The inner ring of the retaining ring 5000 has at least one snap-fit ​​protrusion 510 protruding radially inward. The retaining ring 5000 can be accommodated in the first snap-fit ​​groove 271, and at least one snap-fit ​​protrusion 510 can pass through one of the snap-fit ​​through holes 271a. By providing the first snap-fit ​​groove 271 on the intake pipe 270, and providing the snap-fit ​​through hole 271a on the first snap-fit ​​groove 271, the snap-fit ​​protrusion 510 on the retaining ring 5000 can pass through the snap-fit ​​through hole 271a, thereby achieving a fixed connection between the retaining ring 5000 and the floor brush assembly 2000 through mechanical limiting. The assembly is relatively simple and convenient, and the processing and manufacturing of the intake pipe 270 is also relatively simple. At the same time, the engagement of the snap-fit ​​protrusion 510 with the snap-fit ​​through hole 271a can reduce the size of the opening in the fluid recovery channel, further reducing the airflow pressure loss and helping to maintain a better negative pressure environment, thus making the cleaning effect of this cleaning equipment better.

[0140] In one embodiment, there are two snap-fit ​​holes 271a, and the number of snap-fit ​​protrusions 510 is the same as the number of snap-fit ​​holes 271a. Of course, in other embodiments, the number of snap-fit ​​holes 271a may be greater than or equal to the number of snap-fit ​​protrusions 510, thereby facilitating the snap-fit ​​assembly of the two.

[0141] Please see Figures 11-13 as well as Figures 16-18In some embodiments, the bent pipe connector 410 is provided with an annular slide 411a along its axial direction on the side near the floor brush assembly 2000. Figures 11-13 The snap-fit ​​protrusion 510 passes through the snap-fit ​​through hole 271a and is accommodated within the annular slide rail 411a, and can slide relative to the annular slide rail 411a. By sliding the snap-fit ​​protrusion 510 within the annular slide rail 411a on the annular bend connector 410, the rotatable connection between the snap ring 5000 and the bend connector assembly 4000 is achieved. The assembly process is relatively simple and convenient, saving time and effort.

[0142] In one embodiment, the two snap-fit ​​holes 271a are arranged opposite to each other, and the position of the snap-fit ​​protrusion 510 is adapted to the position of the snap-fit ​​hole 271a, so that the position of the snap-fit ​​protrusion 510 on the snap ring 5000 is more reasonable and the center of gravity is more evenly distributed. When the snap-fit ​​protrusion 510 slides in the annular slide 411a, the sliding process is also more stable.

[0143] Please see Figure 9 and combined Figure 13 In some embodiments, the width d1 of the retaining ring 5000 extending along the first rotation axis is ( Figure 9 As shown, the width d2 of the annular slide 411a along the direction of the first rotation axis is smaller than that of the slide 411a. Figure 13 As shown); specifically, the first rotation axis is Figure 3 and Figure 4 The P-axis in the middle; thus, the retaining ring 5000 is easy to install when installed into the annular slide 411a.

[0144] In one specific embodiment, the width d1 of the retaining ring 5000 along the direction of extension of the first rotation axis ( Figure 9 As shown) and the width d2 of the annular slide 411a along the direction of the first rotation axis ( Figure 13 As shown, the condition is met: 0.1mm+d1≤d2≤0.5mm+d1.

[0145] The width d1 of the retaining ring 5000 along the direction of extension of the first rotation axis is defined. Figure 9 As shown, the width d2 of the annular slide 411a along the first rotation axis satisfies the above conditions, thereby making it easier to install the retaining ring 5000 into the annular slide 411a and effectively reducing the shaking of the retaining ring 5000 in the annular slide 411a.

[0146] In one specific embodiment, d2 = d1 + 0.1 mm. In another specific embodiment, d2 = d1 + 0.5 mm. In yet another specific embodiment, d2 = d1 + 0.3 mm.

[0147] Please see Figure 9 In one specific embodiment, there are two snap-fit ​​protrusions 510, which are symmetrically distributed along the diameter passing through the center of the retaining ring 5000, thereby improving the stability of the retaining ring 5000.

[0148] In one specific embodiment, the retaining ring 5000 is made of elastic plastic or metal, thus being able to withstand a certain degree of deformation.

[0149] Please see Figure 9 In some embodiments, the retaining ring 5000 is configured with a snap-fit ​​opening 520. By providing the snap-fit ​​opening 520 on the retaining ring 5000, it is possible for the retaining ring 5000 to slide into the annular slide rail 411a through the snap-fit ​​opening 520. Specifically, since the retaining ring 5000 can deform to a certain extent, the snap-fit ​​opening 520 can be enlarged during installation, thereby facilitating installation; and when installed into the annular slide rail 411a, the retaining ring 5000 will return to its original deformation, causing the snap-fit ​​opening 520 to return to its reduced state.

[0150] The width d4 of the snap-fit ​​opening 520 and the diameter d3 of the retaining ring 5000 satisfy the condition: 0.2d3≤d4≤0.8d3. By limiting the size of the width d4 of the snap-fit ​​opening 520 and the diameter d3 of the retaining ring 5000, the snap-fit ​​opening 520 can be deformed more easily, thereby snapping into the annular slide rail 411a, making it easier for the retaining ring 5000 to snap into the annular slide rail 411a.

[0151] In one specific embodiment, the width d4 of the snap-fit ​​opening 520 is equal to 0.2 times the diameter d3 of the retaining ring 5000. In another specific embodiment, the width d4 of the snap-fit ​​opening 520 is equal to 0.8 times the diameter d3 of the retaining ring 5000. In yet another specific embodiment, the width d4 of the snap-fit ​​opening 520 is equal to 0.5 times the diameter d3 of the retaining ring 5000.

[0152] Please see Figures 11-13 In some embodiments, the bend connector 410 includes a first connecting portion 411 and a second connecting portion 412. An annular slide 411a is constructed on the first connecting portion 411; the second connecting portion 412 is connected to the side of the first connecting portion 411 away from the floor brush assembly 2000 along the extension direction of the first rotation axis; specifically, the extension direction of the first rotation axis is... Figure 3 , Figure 4 , Figure 11 , Figure 12 as well as Figure 16The second connecting part 412 is partially annular in projection along a plane perpendicular to the extension direction of the first rotating axis; the second connecting part 412 is rotatably connected to the fuselage 1000.

[0153] By projecting the second connecting portion 412 onto a plane perpendicular to the extension direction of the first rotation axis in a partially annular shape, a certain installation space is provided at the second connecting portion 412 when the body 1000 rotates relative to it. This facilitates the connection and rotation of the bent pipe connector 410, which connects the connector head 110 to the dust cup assembly of the body 1000. Furthermore, the annular structure provides more balanced stress distribution, resulting in higher structural strength for the second connecting portion 412.

[0154] Please see Figure 3 , Figure 4 , Figure 11 , Figure 16 as well as Figures 20-21 In some embodiments, the bent pipe connecting assembly 4000 rotates relative to the body 1000 about a second rotating axis; the second rotating axis has multiple relative positions perpendicular to the first rotating axis, and when the first rotating axis and the second rotating axis are held in a fixed first relative position, the body 1000 is in a retracted state; specifically, the second rotating axis is... Figure 3 , Figure 4 , Figure 16 as well as Figures 20-21 The N-axis in the diagram.

[0155] By rotating the bend connecting assembly 4000 relative to the body 1000 around the second rotation axis, the body 1000 can rotate to different angles relative to the floor brush assembly 2000, making the posture of the body 1000 more flexible and versatile than that of the floor brush assembly 2000, facilitating flexible operation by the user and enabling the cleaning of more dead corners.

[0156] In this application, the bent tube connecting assembly 4000 rotates relative to the floor brush assembly 2000 around the first rotating axis, and the bent tube connecting assembly 4000 rotates relative to the body 1000 around the second rotating axis. This allows the assembly angle of the body 1000 relative to the floor brush assembly 2000 to be adjusted and changed more flexibly. The body 1000 has more postures than the floor brush assembly 2000, making it more convenient and easy for users to use.

[0157] In some embodiments, the second connecting portion 412 is configured with a first snap-fit ​​half-groove 4121 ( Figures 11-13 (As shown); the bend connection assembly 4000 also includes a mounting block 420 connected to the second connection portion 412; the mounting block 420 is configured with a second snap-fit ​​half-groove 421 ( Figure 11 and Figure 14As shown); the first snap-fit ​​half-groove 4121 and the second snap-fit ​​half-groove 421 can together form the second snap-fit ​​groove 423 (as shown); Figure 11 and Figure 18 As shown); the fuselage 1000 has a rotating protrusion 20 (as shown); Figure 18 , Figure 20 and Figure 23 (As shown); the rotating protrusion 20 is accommodated in the second snap-fit ​​groove 423 and can rotate relative to the groove wall of the second snap-fit ​​groove 423.

[0158] 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. The snap-fit ​​groove 450 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.

[0159] Please see Figures 20-22 The connector 110 of the fuselage 1000 has an opening groove 1 with 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... Figure 20 The yy' direction; the first direction is Figure 1 , Figure 2 , Figure 4 , Figure 5 , Figure 18 as well as Figure 19 The bend tube connecting assembly 4000 is rotatably connected to the connector 110 (specifically, the bend tube connecting assembly 4000 rotates relative to the connector 110 around a second rotation axis); the floor brush assembly 2000 has an elastic snap-fit ​​assembly 3000 on the side near the connector 110. When the connector 110 rotates relative to the floor brush assembly 2000 to a preset position under the drive of the bend tube connecting assembly 4000, the elastic snap-fit ​​assembly 3000 installed on the floor brush assembly 2000 snaps into the opening slot 1 on the connector 110, thereby keeping the body 1000 in a fixed storage state.

[0160] It should be noted that due to the relatively heavy weight of the camera body 1000, when it is in its stowed state, it needs to be tilted forward relative to the floor brush assembly 2000. This ensures that the center of gravity of the camera body 1000 falls within the projection range of the floor brush assembly 2000, resulting in better stability. Specifically, when the camera body 1000 is in its stowed state... Figure 18The 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.

[0161] It should be noted that, since the posture of the body 1000 relative to the floor brush assembly 2000 is adjustable, the angle between the second direction and the first direction is variable. It can be 0° or any other arbitrary angle value, without any special limitation.

[0162] It should be noted that, because the bend connector 110 rotates relative to the machine body 1000 around the second rotation axis, that is... Figure 3 , Figure 4 , Figure 16 as well as Figures 20-21 When the N-axis rotates, the orientation of the connector 110 relative to the floor brush assembly 2000 changes, which is equivalent to the connector 110 rotating relative to the floor brush assembly 2000.

[0163] When the cleaning equipment is finished and needs to be stored, the connector 110 of the main body 1000 is rotated relative to the floor brush assembly 2000 to a preset position. This allows the elastic snap-fit ​​component 3000 on the floor brush assembly 2000 to engage with the opening slot 1 on the connector 110, thus placing the main body 1000 in its stored state. Because this cleaning equipment directly incorporates the elastic snap-fit ​​component 3000 on the floor brush assembly 2000 and the opening slot 1 on the connector 110 of the main body 1000, the snap-fit ​​connection between the two is achieved through the engagement of the elastic snap-fit ​​component 3000 and the opening slot 1. The entire assembly structure is relatively simple and convenient for users, requiring only rotation of the main body 1000 to a certain position. This not only effectively reduces the overall cost of the cleaning equipment but also simplifies the assembly of the floor brush assembly 2000 and the main body 1000.

[0164] It should be noted that, in this application, the body 1000 maintains its posture in the folded state by directly engaging the elastic snap-fit ​​component 3000 with the opening slot 1. Therefore, compared to the existing structure that sets a set of limiting components on the first rotating shaft and a set of limiting components on the second rotating shaft, the entire technical solution is more streamlined, has lower manufacturing costs, and is easier to assemble.

[0165] Please see Figure 16 as well as Figures 18-21In 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... Figure 16 as well as Figures 20-21 In the xx' direction, the opening groove 1 is constructed on the snap-fit ​​part 10. By constructing the snap-fit ​​part 10 on the connector 110 and the opening groove 1 on the snap-fit ​​part 10, the processing and preparation of the opening groove 1 is relatively convenient and simple.

[0166] Please see Figures 20-22 In some embodiments, the opening groove 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 opening groove 1 is separated from the elastic snap-fit ​​assembly 3000. By providing the second opening 3 in the opening groove 1, the bent tube connecting assembly 4000 can easily slide into or out of the opening groove 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.

[0167] Please see Figure 22 and Figure 24 In some embodiments, the groove wall of the opening groove 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 each other along a fourth direction; both the third direction and the fourth direction are angled to the second direction; specifically, the third direction is... Figure 22 The direction of xx' in the middle; the fourth direction is Figure 22 and Figure 24 The first sidewall 4, the second sidewall 5, and the third sidewall 6 together form the opening groove 1. This arrangement ensures that when the elastic snap-fit ​​assembly 3000 is accommodated within the opening groove 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 compared to the floor brush assembly 2000. Figure 3 , Figure 4 , Figure 16 as well as Figures 20-21 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.

[0168] This application conveniently and simply limits the rotation of the body 1000 relative to the ground brush assembly 2000 around the second rotation axis by using the relatively positioned first sidewall 4 and third sidewall 6. The body 1000 is further limited to not rotating around the first rotation axis by using the two second sidewalls 5 of the two opening slots 1. Simultaneously, since the two opening slots 1 are at a certain distance from both the first and second rotation axes, the increased distance between the body 1000 and the first and second rotation axes reduces torque and increases moment force, making the rotation of the body 1000 more effortless.

[0169] Please see Figure 22 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... Figure 22 In the xx' direction. 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 opening slot 1 is longer on the side closer to the floor brush assembly 2000. This allows the elastic snap-fit ​​assembly 3000 to better limit the body 1000 from tilting forward and falling towards the floor brush assembly 2000 when snapped into the opening slot 1, thus improving safety.

[0170] Please see Figures 22-24 In some embodiments, the side of the first sidewall 4 away from the second sidewall 5 is provided with a first guide slope 4a; 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 around the first rotation axis, and the connector 110 rotates relative to the bent tube connecting assembly 4000 around the second rotation axis, the elastic snap-fit ​​assembly 3000 can slide in or out along the first guide slope 4a during the process of sliding into or out of the opening groove 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.

[0171] Please see Figure 22In some embodiments, the bottom wall 7 of the opening groove 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 opening groove 1 along the second direction is also inclined at the second opening 3. In this application, by setting the bottom wall 7 of the opening groove 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 opening groove 1 can be increased by the parallel segment 7a, so that when the elastic snap-fit ​​assembly 3000 is snapped into the opening groove 1, it can have a larger contact area with the bottom wall 7 of the opening groove 1, and the snap-fit ​​between the two is more stable, thereby making the body 1000 more stable when in the second direction. Figure 1 , Figure 5 and Figure 18 The stability is better when the storage position is close to upright, as shown.

[0172] Please see Figures 22-24 In some embodiments, the third sidewall 6 is provided with 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 side of 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 rotating axis, and the connector 110 rotates relative to the bent tube connecting assembly 4000 about the second rotating axis, the elastic snap-fit ​​assembly 3000 can slide in or out along the second guide slope 6a during the process of sliding into or out of the opening groove 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.

[0173] Please see Figure 22 and Figure 24 In some embodiments, the first sidewall 4 has a first inclined surface 4b on the side facing away from the groove 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... Figures 2-4 The state shown (elastic snap-fit ​​component 3000 separated from opening slot 1) is switched to Figure 1 , Figure 5 and Figure 18When the storage state shown (elastic snap-fit ​​component 3000 snaps into the opening slot 1) is reached, the bent pipe connecting component 4000 needs to rotate relative to the brush component 2000 around the first rotation axis, and the connector 110 needs to rotate relative to the bent pipe connecting component 4000 around the second rotation axis. During this rotation, there is a possibility that the elastic snap-fit ​​component 3000 needs to slide into or out of the opening slot 1 from the side of the first side wall 4 away from the opening slot 1. By setting the first inclined surface 4b, when the elastic snap-fit ​​component 3000 slides into or out of the opening slot 1 from the side of the first side wall 4 away from the opening slot 1, the first inclined surface 4b can guide the elastic snap-fit ​​component 3000 to slide in and out of the opening slot 1.

[0174] Please see Figure 22 and Figure 24 In some embodiments, the third sidewall 6 has a second inclined surface 6b on the side facing away from the groove 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... Figures 2-4 The state shown (elastic snap-fit ​​component 3000 separated from opening slot 1) is switched to Figure 1 , Figure 5 and Figure 18 When the device is in the storage state shown (elastic snap-fit ​​component 3000 snaps into the opening slot 1), the bent pipe connecting component 4000 needs to rotate relative to the brush component 2000 around the first rotation axis, and the connector 110 needs to rotate relative to the bent pipe connecting component 4000 around the second rotation axis. During this rotation, there is a possibility that the elastic snap-fit ​​component 3000 needs to slide into or out of the opening slot 1 from the side of the second side wall 5 away from the opening slot 1. By setting the second inclined surface 6b, when the elastic snap-fit ​​component 3000 slides into or out of the opening slot 1 from the side of the second side wall 5 away from the opening slot 1, the second inclined surface 6b can guide the elastic snap-fit ​​component 3000 to slide in and out easily.

[0175] Please see Figure 23 and Figure 24 In some embodiments, the bottom wall 7 of the opening groove 1 along the second direction, away from the groove cavity of the opening groove 1, is constructed 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... Figures 2-4 The state shown (elastic snap-fit ​​component 3000 separated from opening slot 1) is switched to Figure 1 , Figure 5 and Figure 18When the storage state shown is such that the elastic snap-fit ​​component 3000 is snapped into the opening slot 1, the bent pipe connecting component 4000 needs to rotate relative to the brush component 2000 around the first rotation axis, and the connector 110 needs to rotate relative to the bent pipe connecting component 4000 around the second rotation axis. During this rotation, there is a possibility that the elastic snap-fit ​​component 3000 needs to slide into or out of the opening slot 1 from the side of the third side wall 6 away from the opening slot 1. By setting the third inclined surface 7c, when the elastic snap-fit ​​component 3000 slides into or out of the opening slot 1 from the side of the third side wall 6 away from the opening slot 1, the guiding effect of the third inclined surface 7c can facilitate the sliding in and out of the elastic snap-fit ​​component 3000.

[0176] This application achieves this by setting different guide slopes and inclined surfaces on the side wall and bottom wall 7 of the opening groove 1, so that when the elastic snap-fit ​​component 3000 slides into or out of the opening groove 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 component 2000.

[0177] 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.

[0178] Please see Figure 18 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°.

[0179] Please see Figure 18In 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°.

[0180] Please see Figure 6 In some embodiments, the floor brush assembly 2000 includes a base plate 230, a roller brush 240, and a top cover 250. The base plate 230 is disposed near the surface to be cleaned; the roller brush 240 is rotatably connected to the base plate 230; the top cover 250 is disposed opposite to the base plate 230 along a fifth direction and connected to the base plate 230; specifically, the fifth direction is... Figures 1-4 as well as Figure 6 and Figure 7 The mm' direction; the elastic snap-fit ​​component 3000 is set on the upper cover 250. When the surface to be cleaned needs to be cleaned, the roller brush 240 rotates relative to the base plate 230 and is driven by the motor 7000 to generate negative pressure, so that the mixture of garbage and airflow is rolled away by the roller brush 240 and sucked into the dust cup module 6000 to complete the cleaning operation.

[0181] It should be noted that the fifth direction may or may not be 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 fifth 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 fifth direction.

[0182] Please see Figure 19 In some embodiments, the upper cover 250 has a mounting groove 251 on the side near the base plate 230, and the mounting groove 251 has a third opening 251a along a first direction; specifically, the first direction is... Figure 18 and Figure 19The flexible snap-fit ​​component 3000 is at least partially housed within the mounting groove 251 and is movable within the mounting groove 251 in the first direction. When the connector 110 rotates relative to the ground brush assembly 2000 to a preset position, the flexible snap-fit ​​component 3000 is configured to at least partially extend out of the third opening 251a and snap into the opening groove 1. By providing a mounting groove 251 on the upper cover 250 and a third opening 251a on the mounting groove 251, when the connector 110 of the body 1000 rotates relative to the ground brush assembly 2000 to a preset position, i.e., the retracted state, the flexible snap-fit ​​component 3000 can move along the first direction and extend out of the third opening 251a, thereby snapping into the opening groove 1. The entire movement process is relatively simple and convenient.

[0183] Please see Figure 18 and Figure 19 In some embodiments, the elastic snap-fit ​​assembly 3000 includes an elastic element 310 and a movable element 320. One end of the elastic element 310 abuts against the groove wall of the mounting groove 251 on the side opposite to the third opening 251a; one end of the movable element 320 abuts against the other end of the elastic element 310; wherein, the elastic element 310 is in a compressed state; when the connector 110 rotates relative to the brush assembly 2000 to a preset position, the elastic element 310 can drive the movable element 320 to move away from the elastic element 310 along a first direction and extend out of the third opening 251a. 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 opening slot 1 has a certain space so that the moving element 320 can move along the first direction. The moving element 320 can move along the first direction and extend out of the third opening 251a under the elastic force of the elastic element 310, so that the end of the moving element 320 away from the elastic element 310 is engaged in the opening slot 1. When the moving element 320 is engaged in the opening slot 1, the elastic element 310 can also continuously apply an elastic abutment force to the moving element 320, so that the end of the moving element 320 is not easy to separate from the opening slot 1.

[0184] 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 opening groove 1 will abut against the moving part 320, and the moving part 320 will be squeezed by the groove wall below the opening groove 1, thereby briefly compressing the elastic part 310. The moving part 320 can then briefly leave the opening groove 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.

[0185] Please see Figures 1-7 In some embodiments, the floor brush assembly 2000 further includes a viewing window 260 made of a transparent material. The viewing window 260 is mounted on the side of the roller brush 240 away from the base plate 230 and is fixedly connected to the base plate 230. The viewing window 260 is used to allow the user to easily view the rotation of the roller brush 240.

[0186] Please see Figure 19 and combined Figures 23-24 In some embodiments, a limiting groove 8 is formed on the side of the snap-fit ​​portion 10 opposite to the opening groove 1; the locking block 420 is at least partially accommodated in the limiting groove 8. By forming the limiting groove 8 directly on the side of the snap-fit ​​portion 10 opposite to the opening groove 1, and by allowing the locking block 420 to be at least partially accommodated in the limiting groove 8, the structure of the entire cleaning device becomes more compact.

[0187] Please see Figure 14 and Figure 19 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 upwards along the second direction from the side of the floor brush assembly 2000 toward the body 1000; specifically, the second direction is... Figure 19 The yy' direction in the middle. By setting the curved surface 422, the mounting block 420, driven by the connector 110, rotates relative to the bent pipe connection 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 422 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.

[0188] Please see Figure 19 In some embodiments, 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 5 and Figure 18 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 8The 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.

[0189] Please see Figures 11-13 as well as Figures 16-17 In some embodiments, a sealing track 411b is also constructed on the first connecting portion 411; see also Figure 7 , Figure 8 as well as Figure 15 In some embodiments, the bend connection assembly 4000 further includes a first sealing ring 430; the first sealing ring 430 is sleeved on the sealing track 411b and is sealed to the air intake pipe 270.

[0190] By setting a sealing track 411b and fitting a first sealing ring 430 onto the sealing track 411b and sealing it with the air inlet pipe 270, the sealing performance between the first connection part 411 and the air inlet pipe 270 is improved, thereby making the cleaning equipment more efficient when cleaning the surface to be cleaned.

[0191] Please see Figures 12-13 as well as Figures 16-17 In some embodiments, a second receiving cavity 411c is formed on the first connecting portion 411, the second receiving cavity 411c being used to form a fluid recovery channel; along the fluid recovery direction of the fluid recovery channel; specifically, the fluid recovery direction is... Figure 12 and Figure 13 The direction indicated by the middle arrow is m; that is, along the P-axis of the first rotating shaft, from the ground brush assembly 2000 to the side of the body 1000; the sealing track 411b is located upstream of the annular slide 411a. By setting the sealing track 411b upstream of the annular slide 411a, the installation of the first sealing ring 430 is facilitated, which is beneficial to the sealing within the fluid recovery channel.

[0192] Please see Figure 8 and Figure 15 In some embodiments, the outer ring of the first sealing ring 430 is provided with a sealing lip 431 protruding circumferentially. By providing a sealing lip 431 protruding circumferentially on the outer periphery of the first sealing ring 430, when the first sealing ring 430 is installed between the first connecting part 411 and the air intake pipe 270, the sealing lip 431 can better abut against the sealing track 411b and the air intake pipe 270 due to its own elastic deformation capability, thereby improving the sealing performance between the first connecting part 411 and the air intake pipe 270.

[0193] Please see Figure 8 and combined Figure 15 In some embodiments, the sealing lip 431 is positioned towards the annular slide 411a along the fluid recovery direction of the fluid recovery channel; specifically, the fluid recovery direction is... Figure 12 and Figure 13 The direction of m indicated by the middle arrow. By setting the sealing lip 431 to face the annular slide 411a, that is, by setting the sealing lip 431 to be tilted towards the fluid recovery direction, the tilting direction of the sealing lip 431 is in line with the fluid recovery direction. This allows for better contact with the side wall of the air inlet pipe 270 during fluid flow, effectively ensuring the sealing performance of the connection between the first connection part 411 and the air inlet pipe 270.

[0194] Meanwhile, due to the presence of a sealing lip 431, the first sealing ring 430 contacts the intake pipe 270 only through the sealing lip 431, which has a smaller contact area, while ensuring effective sealing. The small contact area between the two facilitates the rotation of the bent pipe connection assembly 4000 relative to the intake pipe 270.

[0195] In one specific embodiment, the first sealing ring 430 is made of a plastic material.

[0196] Please see Figure 7 and Figure 8 In some embodiments, the bend connection assembly 4000 further includes a flexible hose 440 and a sleeve 450. The upper end of the flexible hose 440 is connected to the body 1000; the sleeve 450 is sleeved around the lower end of the flexible hose 440; and the sleeve 450 is at least partially accommodated within the second receiving cavity 411c; the sleeve 450 is detachably connected to the first connecting portion 411. By providing the flexible hose 440, when the body 1000 rotates relative to the floor brush assembly 2000 in the first or second direction, the rotation can be achieved through the superior bending and deformation capability of the flexible hose 440 itself, resulting in a smoother rotation process. Simultaneously, by providing the sleeve 450, the sleeve 450 can protect the end of the flexible hose 440, and the detachable connection between the sleeve 450 and the first connecting portion 411 allows for the assembly and disassembly of the body 1000 relative to the floor brush assembly 2000.

[0197] It should be noted that, because the flexible hose 440 rotates synchronously with the bending connector 4000 and the floor brush assembly 2000 around the first rotation axis, the flexible hose 440 will not bend when the bending connector 4000 rotates around the first rotation axis. Only when the bending connector 2000 rotates relative to the body 1000 around the second rotation axis can the flexible hose 440 rotate around the second rotation axis towards or away from the floor brush assembly 2000. This makes the flexible hose 440 less prone to twisting along its length, resulting in less damage and a longer service life.

[0198] Please see Figure 10 In some embodiments, the air inlet pipe 270 has a third receiving cavity 272 on the side near the bend connector assembly 4000; the first connecting portion 411 and the sleeve 450 are at least partially received within the third receiving cavity 272. By providing a third receiving cavity 272 in the air inlet pipe 270 and at least partially receiving the first connecting portion 411 and the sleeve 450 within the third receiving cavity 272, the cavity wall of the third receiving cavity 272 of the air inlet pipe 270 protects the ends of the sleeve 450 and the flexible hose 440, and also makes the structure of the entire cleaning device more compact and smaller in size along the first direction.

[0199] Please see Figure 8 In some embodiments, a third snap-fit ​​groove 451 is formed on the sleeve 450; an elastic buckle 411d is provided on the circumferential sidewall of the second receiving cavity 411c. Figures 11-13 as well as Figures 16-17 The snap-fit ​​portion of the elastic snap fastener 411d is housed within the third snap-fit ​​groove 451. The snap-fit ​​connection between the snap-fit ​​portion of the elastic snap fastener 411d and the third snap-fit ​​groove 451 enables a detachable connection between the first connecting portion 411 and the sleeve 450, which is relatively simple and convenient.

[0200] Please see Figure 28In some embodiments, the third snap-fit ​​groove 451 is arranged along the outer circumference of the sleeve 450, so that its fixation with the elastic buckle 411d is not limited by angle. The flexible hose 440 is fixed to the sleeve 450 by threads and reinforced and sealed with glue, etc. The flexible hose 440 and the connector 110 are also fixed by a similar process. The flexible hose 440 is extruded and is generally very long when formed. It is cut to a certain length for installation. Because the flexible hose 440 has a certain degree of elasticity, it is impossible to guarantee that all flexible hoses 440 have a certain number of spiral turns. Therefore, if both ends of the flexible hose 440 are fixed to a certain position by threads, it may cause the flexible hose 440 to be in a twisted state. During use, the user will feel a bit stuck. In addition, it will also affect the life and sealing performance of the flexible hose 440. By setting the sleeve 450, both ends of the flexible hose 440 can be easily fixed. After the upper part is installed, one end of the sleeve 440 can be directly inserted into the air inlet pipe 270. The flexible hose 440 does not bear torque.

[0201] In some embodiments, the flexible hose 440 is a spiral wound tube that can withstand deformation in multiple directions.

[0202] It should be noted that corrugated pipes are a common type of connecting pipe fitting, and their assembly is simple, but their disadvantage is that they cannot be twisted. In this application, since a sleeve 450 is provided on the outer periphery of the flexible hose 440, the stress on the flexible hose 440 can be improved through the sleeve 450. Therefore, a corrugated pipe can be selected for the flexible hose 440, resulting in better economic benefits.

[0203] In some other embodiments, since the flexible hose 440 of this application only needs to rotate about the second rotation axis along the side toward or away from the floor brush assembly 2000, it is not easy for it to twist along its length extension direction. Therefore, when the flexible hose 440 is selected as a corrugated pipe in this application, the sleeve 450 can also be omitted, without any special limitation.

[0204] Please see Figure 10 In some embodiments, the third accommodating cavity 272 has a first opening groove 272a on its cavity wall; the first opening groove 272a has an opening facing a first direction; the first direction is the direction from which the air inlet pipe 270 points to the bent pipe connector 410; by providing the first opening groove 272a, the cavity wall of the third accommodating cavity 272 has a certain elasticity, making it easier to deform, thereby facilitating the engagement with the sleeve 450. It also reduces the radial dimension of the air inlet pipe 270, thus reducing interference when the air inlet pipe 270 is assembled with the upper cover 250 on the floor brush assembly 2000. Optionally, the first opening groove 272a can be a U-shaped groove for easier processing.

[0205] Please see Figure 11 , Figure 12 , Figure 16 as well as Figure 17 In some embodiments, the outer peripheral wall of the first connecting part 411 is provided with a plurality of spaced-apart snap-fit ​​protrusions 411e. When the first connecting part 411 rotates relative to the air inlet pipe 270, the snap-fit ​​protrusions 411e can abut against the cavity wall of the third accommodating cavity 272, thereby reducing the contact area and reducing resistance. After the first connecting part 411 and the air inlet pipe 270 are assembled, when the cleaning equipment is working and the body 1000 rotates relative to the brush assembly 2000 around the first rotating axis, the snap-fit ​​protrusions 411e abut against the inner wall of the third accommodating cavity 272, which can also reduce the possibility of relative shaking between the two.

[0206] Please see Figure 8 In some embodiments, the bend connection assembly 4000 further includes a second sealing ring 460; the second sealing ring 460 is sleeved on the outer periphery of the sleeve 450 and abuts against the inner wall of the second receiving cavity 411c, and along the fluid recovery direction of the fluid recovery channel, the second sealing ring 460 is located upstream of the third snap-fit ​​groove 451. By providing the second sealing ring 460 and positioning it upstream of the third snap-fit ​​groove 451, sealing is facilitated, resulting in less air pressure loss in the entire fluid recovery channel and better cleaning effect.

[0207] Please see Figure 13 and combined Figure 8 In some embodiments, along the fluid recovery direction of the fluid recovery channel, the second accommodating cavity 411c includes a first sub-cavity 411c1, a second sub-cavity 411c2, and a third sub-cavity 411c3 that are interconnected and whose diameters increase sequentially; specifically, the diameter of the first sub-cavity 411c1 is... Figure 13 d5; the diameter of the second sub-cavity 411c2 is Figure 13 The diameter of d6 in the third sub-cavity 411c3 is... Figure 13 In this configuration, d7; the retaining ring 5000 is located on the outer periphery of the first sub-cavity 411c1; the second sealing ring 460 is located inside the second sub-cavity 411c2; and the elastic buckle 411d is constructed on the third sub-cavity 411c3. By setting the second accommodating cavity 411c as the first sub-cavity 411c1, the second sub-cavity 411c2, and the third sub-cavity 411c3 with successively increasing diameters, and with the retaining ring 5000, the second sealing ring 460, and the elastic buckle 411d respectively located at the first sub-cavity 411c1, the second sub-cavity 411c2, and the third sub-cavity 411c3, the radial dimension change of the fluid recovery channel at this location is minimized, thereby reducing pressure loss and sudden drops caused by excessive radial pressure changes when the fluid flows through this location.

[0208] Please see Figure 8 In some embodiments, a sealing protrusion 452 is provided on the side of the sleeve 450 near the first connecting portion 411, and the sealing protrusion 452 is positioned towards the flexible hose 440 along the fluid recovery direction of the fluid recovery channel. The end of the flexible hose 440 can be engaged between the sealing protrusion 452 and the mounting groove 453 formed by the inner wall of the sleeve 450. By providing the sealing protrusion 452 and engaging the end of the flexible hose 440 in the mounting groove 453, the connection between the sleeve 450 and the flexible hose 440 achieves better sealing.

[0209] Please see Figure 5 and combined Figure 18 In some embodiments, the floor brush assembly 2000 further includes a base plate 230; the front wheel assembly 210, the rear wheel assembly 220, and the air intake pipe 270 are all mounted on the base plate 230; the base plate 230 is configured with a first receiving cavity 231, and the first receiving cavity 231 is disposed between the front wheel assembly 210 and the rear wheel assembly 220; the bent pipe connecting assembly 4000 is at least partially received within the first receiving cavity 231. By constructing the first receiving cavity 231 on the base plate 230, and making the bent pipe connecting assembly 4000 at least partially received within the first receiving cavity 231, the bent pipe connecting assembly 4000 has a certain rotation space relative to the floor brush assembly 2000 and the body 1000 through the first receiving cavity 231, and the rotation process is relatively smooth.

[0210] 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.

[0211] 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.
