[0106] 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.

[0107] 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.

[0108] 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.

[0109] 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.

[0110] 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.

[0111] 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.

[0112] See Figure 1 , Figure 2 as well as Figure 15 , Figure 1 A first schematic diagram is shown, illustrating the cleaning apparatus provided in some embodiments of this application in a first state. Figure 2 It shows Figure 1 A second schematic diagram of the cleaning device shown. Figure 15 It shows Figure 1 The diagram shows the cleaning device in its fourth state. An embodiment of this application provides a cleaning device including a floor brush assembly 100, a dust cup assembly 200, a power assembly 300, an extension rod assembly 400, and a handle 500. The dust cup assembly 200 is detachably connected to the floor brush assembly 100; the power assembly 300 is mounted on the side of the dust cup assembly 200 opposite to the floor brush assembly 100; the power assembly 300 includes a mounting housing 310 and a first handle 320 mounted on the mounting housing 310; the extension rod assembly 400 has a fluid channel 401; the extension rod assembly 400 has a first state and a second state; in the first state ( Figure 1 and Figure 2 In the state shown, the extension rod assembly 400 is detachably connected between the dust cup assembly 200 and the floor brush assembly 100; in the second state ( Figure 15 In the state shown, the extension rod assembly 400 is detachably connected to the side of the power assembly 300 away from the floor brush assembly 100; the handle 500 is configured with a second handle 510; in the second state, the handle 500 is detachably connected to the side of the extension rod assembly 400 away from the power assembly 300.

[0113] The cleaning device provided in this application, when in use, features a first handle 320 mounted on the mounting housing 310 of the power assembly 300. Therefore, the user can directly operate the cleaning device by holding the first handle 320. This arrangement is more convenient for the user when powering or supplying power to the entire cleaning device via the power assembly 300, compared to the conventional arrangement where the handle is mounted on an additional handle 500. Furthermore, the inclusion of an extension rod assembly 400 and a handle 500 allows for adjustment of the size and structure of the entire cleaning device by changing the state of the extension rod assembly. This enables the user to select... Figure 1 and Figure 2 The extended cleaning structure shown allows the user to grip the second handle 510 for cleaning operations; alternatively, the user can choose... Figure 13 The shorter cleaning structure shown or Figure 15 The cleaning structure shown is of a suitable length, allowing the user to hold the first handle 320 for cleaning operations; thus, this cleaning device can be assembled to different lengths according to the usage scenario, such as sofas, cabinet tops, roofs, ceilings, and other different usage scenarios, making it more widely applicable.

[0114] It should be noted that when the extension rod assembly 400 is in Figure 1 and Figure 2 In the first state shown, this application places the lighter extension rod assembly 400 on the side of the power assembly 300 away from the ground brush assembly 100, thus... Figure 1 and Figure 2 When the extended cleaning structure is in its extended configuration, the center of gravity of the entire cleaning device is lowered, making it more convenient for the user to use. Figure 1 When stored upright as shown, the entire device is more stable because of its low center of gravity, making it easier to maintain an upright position.

[0115] This application moves the power unit 300 away from the user in the first state, thereby making the heavier power unit 300 closer to the ground, thus reducing the force required by the user and making it easier and less strenuous for the user to operate.

[0116] It should be noted that, since a detachable extension rod assembly 400 is provided, and a fluid channel 401 needs to be formed within the extension rod assembly 400, the sealing problem at the connection between the extension rod assembly 400 and the dust cup assembly 200 and the floor brush assembly 100 needs to be considered when the extension rod assembly 400 is in the first state. Therefore, this application sets the extension rod assembly 400 as an extension rod body 410 and a bushing 420. By providing a fixing groove 412 on the extension rod body 410 and a locking protrusion 422, a locking lip 423, and a groove 424 on the bushing 420, the sealing performance when the extension rod assembly 400 is connected to the dust cup assembly 200 and the floor brush assembly 100 is effectively guaranteed through the mutual cooperation of the structural components on the extension rod body 410 and the bushing 420. For a detailed analysis of the sealing process and locking process, please refer to the description of the extension rod body 410 and the bushing 420 below, which will not be repeated here.

[0117] In some embodiments, the handle 500 is provided with a winding end and hook for winding and storing the power cord on the side opposite to the second handle 510.

[0118] In one specific embodiment, the mounting housing 310 is configured with a first mounting cavity, in which a power component is installed to supply power to the entire cleaning device.

[0119] The following is a detailed description of the structure of the cleaning device. Please refer to [link / reference]. Figures 2-14 as well as Figures 16-19 , Figure 2 It shows Figure 1 A second schematic diagram of the cleaning device shown. Figure 3 It shows Figure 2 A magnified view of a portion at point A shown. Figure 4 It shows Figure 2 A magnified view of point B shown. Figure 5 It shows Figure 4 The diagram shows the structure of the first locking element 330. Figure 6 It shows Figure 1 A schematic diagram showing the connection between the power unit 300 and the extension rod assembly 400 in the cleaning device shown. Figure 7 It shows Figure 1 A schematic diagram of the extension rod assembly 400 in the cleaning device shown. Figure 8 It shows Figure 7 A schematic diagram of bushing 420 is shown. Figure 9 It shows Figure 7 A magnified view of point C shown. Figure 10 It shows Figure 1 A schematic diagram of the dust cup assembly 200 in the cleaning device shown. Figure 11 It shows Figure 10The top view of the dust cup assembly 200 shown. Figure 12 It shows Figure 11 The sectional view shown at DD. Figure 13 It shows Figure 1 The diagram shows the cleaning device in its second state. Figure 14 It shows Figure 1 The diagram shows the cleaning device in its third state. Figure 16 It shows Figure 1 The diagram shows the cleaning device in its fifth state. Figure 17 It shows Figure 1 A schematic diagram of the internal components of the power unit in the cleaning device shown. Figure 18 It shows Figure 1 A schematic diagram of the connection end of the second floor brush in the cleaning device shown. Figure 19 It shows Figure 1 A partial cross-sectional view of the extension rod assembly shown.

[0120] Please see Figure 1 In some embodiments, the first handle 320 includes a first grip portion 321, the extension direction of the first grip portion 321 being along a straight line ( Figure 1 The dashed line a) in the middle is the straight line containing the axis of the dust cup assembly 200 dust cup duct 211. Figure 1 The included angle θ of the dashed line b) in the diagram satisfies the condition: 0≤θ≤45°.

[0121] Because the angle θ between the straight line extending from the first grip portion 321 on the first handle 320 and the straight line containing the axis of the dust cup assembly 200's dust cup duct 211 is within a small range of 0° to 45°, the extension direction of the first grip portion 321 can be aligned as closely as possible with the axis of the dust cup duct 211. This allows the user to minimize the distance between the first grip portion 321 and the ground during use. Consequently, in a cleaning device design at the same height, this device can reach further into hard-to-clean areas such as under sofas and beds, effectively increasing the cleaning range of the device.

[0122] In one specific embodiment, the angle θ between the line extending from the first grip 321 and the line containing the axis of the dust cup assembly 200's dust cup duct 211 is 0°. That is, they are parallel. In another specific embodiment, the angle θ between the line extending from the first grip 321 and the line containing the axis of the dust cup assembly 200's dust cup duct 211 is 45°. In yet another specific embodiment, the angle θ between the line extending from the first grip 321 and the line containing the axis of the dust cup assembly 200's dust cup duct 211 is 20°.

[0123] Please see Figure 1 In some embodiments, the first handle 320 further includes two first connecting portions 322, which are respectively connected to the two ends of the first grip portion 321 and fixedly connected to the mounting housing 310.

[0124] Please see Figure 1 In some embodiments, the second handle 510 includes a second grip portion 511;

[0125] The extension direction of the second gripping part 511 ( Figure 1 The straight line containing the dashed line c) intersects the straight line containing the axis of the fluid channel 401 of the extension rod assembly 400. Figure 1 The angle α between the dashed line d) is greater than the angle θ between the straight line extending from the first grip 321 and the straight line containing the axis of the dust cup duct 211 of the dust cup assembly 200. This arrangement ensures that the first handle 320 and the second handle 510 are not shared and have different grip angles, thereby improving the cleaning device's... Figure 1 In the first state shown, it is more convenient for users to push and pull; while in the second state... Figure 13 In the second state shown, the cleaning device is more convenient for the user to pull back and forth when lying flat. Compared to existing solutions that set the included angles α and θ to the same angle, the cleaning device provided in this application is more convenient and smoother to operate.

[0126] It should be noted that in some embodiments, the straight line containing the axis of the fluid channel 401 of the extension rod assembly 400 is parallel to the straight line containing the axis of the dust cup duct 211 of the dust cup assembly 200.

[0127] Please see Figure 1 In some embodiments, the second handle 510 further includes two second connecting portions 512, which are respectively connected to the two ends of the second grip portion 511 and fixedly connected to the handle 500.

[0128] Please see Figure 1 In some embodiments, the distance d between the first grip 321 and the axis b of the dust cup duct 211 of the dust cup assembly 200 satisfies the condition: 10cm ≤ d ≤ 30cm. Specifically, the axis of the dust cup duct 211 can be... Figure 12The central axis of one of the filter elements shown is, for example, the central axis of the second filter element 230. By setting the distance d between the first grip 321 and the axis of the dust cup duct 211 of the dust cup assembly 200 to be greater than or equal to 10cm and less than or equal to 30cm, the distance d between the first grip 321 and the axis of the dust cup duct 211 is relatively close while still providing sufficient grip space for the user. This minimizes the distance between the first grip 321 and the ground during use. Consequently, in a cleaning device design of the same height, this device can reach further into hard-to-clean areas such as under sofas and beds, effectively increasing the cleaning range of the cleaning device.

[0129] In one specific embodiment, the distance d between the first grip portion 321 and the axis of the dust cup duct 211 of the dust cup assembly 200 is 10 cm. In another specific embodiment, the distance d between the first grip portion 321 and the axis of the dust cup duct 211 of the dust cup assembly 200 is 30 cm. In yet another specific embodiment, the distance d between the first grip portion 321 and the axis of the dust cup duct 211 of the dust cup assembly 200 is 20 cm.

[0130] Please see Figure 1 In some embodiments, along the extending direction of the dust cup assembly 200, that is Figure 1 In the zz' direction, the distance h1 between the lowest point of the first grip 321 and the floor brush assembly 100 is greater than the distance h2 between the highest point of the dust cup assembly 200 and the floor brush assembly 100. This arrangement makes the distance between the first grip 321 and the floor brush assembly 100 greater, allowing the user to reach deeper into cleaning hard-to-reach areas when performing cleaning operations, effectively increasing the cleaning range of this cleaning device.

[0131] Please see Figure 1In some embodiments, the angle θ between the straight line extending from the first grip 321 and the straight line containing the axis of the dust cup assembly 200's dust cup air duct 211 satisfies the condition: 0 ≤ θ ≤ 10°. By ensuring that the angle θ between the straight line extending from the first grip 321 on the first handle 320 and the axis of the dust cup assembly 200's dust cup air duct 211 is within a small range greater than or equal to 0° and less than or equal to 10°, the extension direction of the first grip 321 can be as close as possible to the axis of the dust cup air duct 211, making them approximately parallel. During use, the user can minimize the distance between the first grip 321 and the ground, allowing the floor brush assembly 100 to be closer to the ground, approaching a lying position. This design allows the cleaning device, at the same height, to reach deeper into cleaning hard-to-reach areas such as under sofas and beds, effectively increasing the cleaning range of the cleaning device.

[0132] In one specific embodiment, the angle θ between the line extending from the first grip 321 and the line containing the axis of the dust cup duct 211 of the dust cup assembly 200 is 0°. That is, they are parallel. In another specific embodiment, the angle θ between the line extending from the first grip 321 and the line containing the axis of the dust cup duct 211 of the dust cup assembly 200 is 10°. In yet another specific embodiment, the angle θ between the line extending from the first grip 321 and the line containing the axis of the dust cup duct 211 of the dust cup assembly 200 is 5°.

[0133] Please see Figure 7 In some embodiments, the extension rod assembly 400 includes an extension rod body 410 and bushings 420; there are two bushings 420, each bushing 420 being embedded and snapped into one end of the extension rod body 410; both ends of the extension rod body 410 are detachably connected to the power assembly 300 and the handle 500, respectively. Through the cooperation between the bushings 420 and the extension rod body 410, the bushings 420 can provide a certain degree of support for the extension rod body 410, thereby reducing the possibility of deformation of the slender extension rod body 410.

[0134] Specifically, in one particular embodiment, the extension rod body 410 is made of metal, while the bushing 420 is made of plastic. Therefore, their heat shrinkage ratios differ. Since the extension rod body 410 has a thin-walled structure, its strength is not high. The bushings 420 at both ends support the extension rod body 410, thereby reducing the possibility of deformation.

[0135] Please see Figure 7 and combined Figure 6 and Figure 8In some embodiments, the outer wall of the bushing 420 is provided with an elastic protrusion 421; the extension rod body 410 is provided with a snap-fit ​​hole 411; the elastic protrusion 421 can extend into the snap-fit ​​hole 411 and snap-fit ​​with the hole wall of the snap-fit ​​hole 411. Through the elastic deformation of the elastic protrusion 421 itself, the bushing 420 and the extension rod body 410 are snap-fitted, and the assembly process is relatively simple and convenient.

[0136] Please see Figure 8 The bushing 420 has an elastic protrusion 421 with a hollow structure on its outer periphery. This allows the hollow structure to move when the bushing 420 is embedded in the end of the extension rod body 410, making it easier for the elastic protrusion 421 to be engaged in the snap-fit ​​hole 411.

[0137] Please see Figure 8 In some embodiments, the elastic protrusion 421 extends from the middle of the extension rod body 410 towards both ends, that is, along... Figure 8 The m in the middle is tilted so that during the installation of the bushing 420 and the extension rod body 410, the elastic protrusion 421 moves toward the axis of the extension rod body 410. When the elastic protrusion 421 moves to the mounting hole position of the extension rod body 410, the elastic protrusion 421 releases the squeezing force applied to it by the inner wall of the extension rod and returns to the initial position, thereby realizing the snap-fit ​​connection between the two.

[0138] In one specific embodiment, each bushing 420 is symmetrically provided with two elastic protrusions 421, thereby fixing the extension rod assembly 400 to the bushing 420 through the symmetrically arranged elastic protrusions 421. Of course, in other embodiments, each bushing 420 may also be provided with one, three, or four equal elastic protrusions 421, and there is no special limitation on this.

[0139] In one specific embodiment, the bushing 420 is inclined on the side near the end of the extension rod body 410 to facilitate its installation guidance with other components. Specifically, a chamfer may be provided on the side of the bushing 420 near the end of the extension rod body 410.

[0140] Please see Figure 7 and combined Figure 6 , Figure 8 and Figure 9 In some embodiments, the two ends of the extension rod body 410 are also provided with fixing slots 412; both the power assembly 300 and the handle 500 are provided with locking members 600 that are rotatably connected; when the locking member 600 rotates relative to the power assembly 300 or the handle 500 to a first preset position, the locking part 610 of the locking member 600 is inserted into the fixing slot 412; specifically, the first preset position is... Figure 9The position is shown. The extension rod body 410 is connected to the power assembly 300 and the handle 500 by the engagement of the locking part 610 on the locking member 600 with the fixing slot 412, which is relatively simple and convenient. In one specific embodiment, the bottom of the handle 500 is provided with an extension rod assembly 400 mounting cavity and a locking member 600.

[0141] Please see Figure 9 In some embodiments, the locking member 600 further includes an elastic portion 620, which abuts against the power component 300 or the handle 500. When the locking member 600 is pressed, the elastic portion 620 can deform, thereby causing the locking member 600 and the power component 300 or the handle 500 to rotate relative to each other, thereby allowing the locking part 610 to extend into or retract from the fixing slot 412 to achieve a change in the position of the locking member 600.

[0142] Please see Figure 7 and combined Figure 19 In some embodiments, the fixing groove 412 extends through the extension rod body 410 along a direction perpendicular to its extension direction; the bushing 420 has a radially protruding locking protrusion 422; when the bushing 420 is fitted into the end of the extension rod body 410, the locking protrusion 422 at least partially surrounds the outer periphery of the groove wall of the fixing groove 412 and abuts against the inner sidewall of the extension rod body 410. Due to the limitations of the manufacturing process, the extension rod body 410 can only have a fixing groove 412, at which point the locking protrusion 422 protruding from the bushing 420 ( Figure 19 (As shown) At least around the outer periphery of the groove wall of the fixed slot 412, thereby sealing the fixed slot 412, reducing the possibility of air leakage, and ensuring the cleaning effect.

[0143] It should be noted that there is no special limitation on whether the protrusion 422 is entirely surrounded by the outer periphery of the groove wall of the fixed groove 412 or only partially surrounded by the groove wall of the fixed groove 412. It can be adaptively adjusted according to the specific shape and structure of the bushing 420. For example, when the bushing 420 is set as a stepped structure at the corresponding position of the fixed groove 412, only that part of the protrusion 422 needs to be surrounded by the outer periphery of the groove wall of the fixed groove 412, while the other part is sealed and engaged by the body structure of the stepped bushing 420 itself.

[0144] In some embodiments, the end of the bushing 420 is further provided with a snap-fit ​​lip 423 protruding radially outward; when the bushing 420 is embedded and snapped into the end of the extension rod body 410, the snap-fit ​​lip 423 abuts against the end of the extension rod body 410. In this way, the fixing groove 412 is sealed by the secondary sealing effect of the snap-fit ​​lip 423, reducing the possibility of air leakage and ensuring the cleaning effect.

[0145] In some embodiments, the bushing 420 is further provided with a groove 424 formed by a radial inward recess, and the groove 424 has a bottom wall along the radial direction of the bushing 420; when the locking member 600 rotates relative to the power component 300 or the handle 500 to a first preset position, the end of the locking part 610 facing away from the locking member 600 extends into the groove 424. By providing a groove 424 on the bushing 420, and since the groove 424 has a bottom wall along the radial direction of the bushing 420, it is indicated that the groove 424 does not penetrate the bushing 420. When the locking member 600 rotates relative to the power component 300 or the handle 500 to the first preset position, the end of the locking part 610 facing away from the locking member 600 extends into the groove 424. In this way, the bottom wall of the groove 424 can restrict airflow from the fixed slot 412 and through the bushing 420 structure, effectively ensuring the sealing effect of the entire cleaning device.

[0146] In some embodiments, in the second state, the handle 500 is detachably connected to the end of the extension rod assembly 400. This detachable connection makes assembly of the handle 500 with the end of the extension rod assembly 400 easier and effectively ensures the strength of the entire cleaning device after the extension rod assembly 400 is connected to the handle 500.

[0147] Please see Figure 13 and Figure 14 In some embodiments, the mounting housing 310 has a mounting end face 311 on the side opposite to the floor brush assembly 100; a first mounting hole 3111 is provided on the mounting end face 311; the extension rod assembly 400 is detachably connected to the wall of the first mounting hole 3111. By providing the first mounting hole 3111 on the mounting end face 311, the extension rod assembly 400 is assembled and connected to the first mounting hole 3111. Specifically, the locking member 600 is provided at the wall of the first mounting hole 3111, and the locking part 610 of the locking member 600 passes through the wall of the first mounting hole 3111 and can move relative to the wall of the first mounting hole 3111, thereby realizing engagement or disengagement with the fixing slot 412.

[0148] Please see Figure 1 and combined Figure 2 and Figure 4 In some embodiments, the connection between the extension rod assembly 400 and the power assembly 300 is located at the end of the power assembly 300 facing away from the floor brush assembly 100, and the first connection between the extension rod assembly 400 and the power assembly 300 does not protrude from the mounting end face 311. This arrangement allows for easy access when the cleaning device needs to be moved from... Figure 1 and Figure 2 The first state shown is adjusted to Figure 13In the second state shown, simply removing the handle 500 and the extension rod assembly 400 is very convenient. Compared to the traditional structure that includes an additional mounting section between the power assembly 300 and the extension rod assembly 400, the overall structure and assembly of the cleaning device are much simpler.

[0149] Please see Figure 1 , Figure 2 and combined Figures 13-17 In some embodiments, the mounting end face 311 is disposed on the upper end face of the mounting housing 310 on the side opposite to the floor brush assembly 100; the first handle 320 is mounted on the side of the mounting housing 310, and the mounting end face 311 intersects with the side of the mounting housing 310. This arrangement allows the user to easily move the cleaning device from... Figure 1 and Figure 2 The first state shown is adjusted to Figure 13 In the second state shown, the handle 500 and extension rod assembly 400 can be removed to hold the first handle 320 for cleaning operations, avoiding interference or obstruction when the user holds the first handle 320. The assembly and disassembly of the entire cleaning device in different states is also more convenient.

[0150] Please see Figure 15 In some embodiments, the distance h3 between the mounting end face 311 and the floor brush assembly 100 is greater than or equal to the maximum distance h4 between the first grip portion 321 and the floor brush assembly 100. This arrangement ensures that the dust cup assembly 200 can stand upright against the mounting end face 311 when the entire cleaning device is in its flat, stowed state, i.e., when the mounting end face 311 is in contact with the ground.

[0151] Please see Figure 13 and Figure 14 In some embodiments, the mounting end face 311 is provided with an accessory mounting groove 3112; the accessory mounting groove 3112 is capable of engaging at least one ground brush in the ground brush assembly 100. See also... Figure 1 , Figure 2 and Figure 15 In some embodiments, the floor brush assembly 100 also includes a second floor brush 120, which can be a two-in-one brush, a two-in-one flat brush, or a pet brush, etc. It is small in size and can be installed in the accessory mounting slot 3112 when not in use, reducing the possibility of the second floor brush 120 being placed alone and lost.

[0152] In one specific embodiment, the upper surfaces of the accessory mounting groove 3112 and the first mounting hole 3111 do not protrude from the mounting end face 311, so that when it is not necessary to mount the extension rod assembly 400 and the accessory floor brush on the mounting end face 311, the mounting end face 311 can be facing downward and in contact with the ground, thereby allowing the entire cleaning device to be stored upside down, reducing the floor space occupied by the entire cleaning device.

[0153] Please see Figure 1 and Figures 13-16 The accessory mounting groove 3112 and the first mounting hole 3111 are spaced apart on the mounting end face 311, and the two are respectively located at both ends of the axis of the power component 300, which makes the structure of the entire cleaning device more compact and the gravity distribution more reasonable, further reducing the space occupied by the entire device.

[0154] In some embodiments, the mounting end face 311 is generally circular and approximately coaxial with the motor of the power assembly 300. Furthermore, both the accessory mounting groove 3112 and the first mounting hole 3111 are located within the mounting end face 31, thus reducing the overall thickness of the cleaning device. Figure 1 In the mode shown, the dust cup assembly 200 and the power assembly 300 can be closer to the ground, with a compact structure and better stability.

[0155] Please see Figures 13-17 In some embodiments, the accessory mounting slot 3112 is disposed between the first grip portion 321 and the first mounting hole 3111. This arrangement allows for... Figure 1 In the state shown, the user is standing Figure 1 The second handle 510 is operated by gripping the right side of the plane shown, while the second floor brush 120, installed in the accessory mounting slot 3112, is stored in... Figure 1 The right side of the plane shown can reduce the impact of the second floor brush 120 on the user's operation, and can also prevent the second floor brush 120 from obstructing the device from lying flat when the entire cleaning device needs to be tilted down.

[0156] Please see Figure 17 In some embodiments, the inner diameter d1 of the accessory mounting slot 3112 is larger than the inner diameter d2 of the extension rod assembly 400. By setting the inner diameter d1 of the accessory mounting slot 3112 to be larger than the inner diameter d2 of the extension rod assembly 400, it is possible to avoid the extension rod assembly 400 being misinstalled in the accessory mounting slot 3112, and the second floor brush 120, as an accessory, being misinstalled in the first mounting hole 3111. 。

[0157] Please see Figure 17In some embodiments, a mounting protrusion 31121 is provided inside the accessory mounting groove 3112 along the axial direction of the mounting groove 3112; the upper surface of the mounting protrusion 31121 is flush with the mounting end face 311 and has a marking. By providing a mounting protrusion in the accessory mounting groove 3112 and marking it, it is possible to effectively prevent the user from mistakenly installing the extension rod assembly 400 in the accessory mounting groove 3112, and the second floor brush 120, which is an accessory, in the first mounting hole 3111.

[0158] Please see Figure 17 In some embodiments, the outer diameter d3 of the mounting protrusion 31121 is larger than the inner diameter d2 of the extension rod assembly 400. This arrangement further prevents users from mistakenly installing the extension rod assembly 400 into the accessory mounting slot 3112, and from mistakenly installing the second floor brush 120 (as an accessory) into the first mounting hole 3111.

[0159] Please see Figure 17 In some embodiments, the diameter d4 of the mounting end face 311, the inner diameter d1 of the accessory mounting groove 3112 and the diameter d5 of the first mounting hole 3111 satisfy the condition: 0.5d4≤d1+d5≤0.98d4.

[0160] By limiting the size relationship between the diameter d4 of the mounting end face 311, the inner diameter d1 of the accessory mounting groove 3112, and the diameter d5 of the first mounting hole 3111, the above conditions are met, thereby making the structure of the entire cleaning device more compact and occupying less space.

[0161] In one specific embodiment, the diameter d4 of the mounting end face 311, the inner diameter d1 of the accessory mounting groove 3112, and the diameter d5 of the first mounting hole 3111 satisfy the condition: 0.5d4 = d1 + d5. In another specific embodiment, the diameter d4 of the mounting end face 311, the inner diameter d1 of the accessory mounting groove 3112, and the diameter d5 of the first mounting hole 3111 satisfy the condition: 0.98d4 = d1 + d5. In yet another specific embodiment, the diameter d4 of the mounting end face 311, the inner diameter d1 of the accessory mounting groove 3112, and the diameter d5 of the first mounting hole 3111 satisfy the condition: 0.75d4 = d1 + d5.

[0162] Please see Figure 17 and combined Figure 18 In some embodiments, the floor brush assembly 100 includes a second floor brush 120; the inner diameter d1 of the accessory mounting groove 3112 is adapted to the outer diameter d6 of the connecting end 121 of the second floor brush 120. By setting the inner diameter d1 of the accessory mounting groove 3112 to be adapted to the outer diameter d6 of the connecting end 121 of the second floor brush 120, the flexible assembly and disassembly of the two are facilitated.

[0163] In some embodiments, the axis of the power assembly 300 passes through the line connecting the inner diameter center of the accessory mounting groove 3112 and the inner diameter center of the first mounting hole 3111. This arrangement makes the layout of the entire cleaning device more compact, thereby reducing the space occupied by the entire cleaning device.

[0164] Please see Figure 4 and Figure 5 In some embodiments, the power assembly 300 further includes a first locking member 330; the first locking member 330 is disposed on the side of the first handle 320 near the dust cup assembly 200; the side of the dust cup assembly 200 near the power assembly 300 has a first locking groove 212; the first locking member 330 has a locked position and a released position relative to the first locking groove 212; in the locked position, the first locking member 330 extends into the first locking groove 212; in the released position, the first locking member 330 is separated from the first locking groove 212. By adjusting the position of the first locking member 330 relative to the first locking groove 212, the assembly and disassembly of the dust cup assembly 200 relative to the power assembly 300 can be conveniently achieved.

[0165] Please see Figure 5 In some embodiments, the first locking member 330 includes a first pressing unit 331 and a first locking unit 332. The first pressing unit 331 is mounted on the first handle 320; one end of the first locking unit 332 is rotatably connected to the mounting housing 310, and the other end of the first locking unit 332 is provided with a first locking protrusion 3321; the first pressing unit 331 and the first locking unit 332 elastically abut against each other; the first locking unit 332 can rotate around the mounting housing 310 under the drive of the first pressing unit 331, so that the first locking protrusion 3321 extends into or out of the first locking groove 212. When it is necessary to detach the dust cup assembly 200 from the power assembly 300, the first pressing unit 331 is pressed, which allows the first locking unit 332 to rotate around the mounting shell 310, thereby causing the first locking protrusion 3321 to extend out of the first locking groove 212, thus achieving separation of the two. After the two are separated, the first locking unit 332 can be elastically reset because the first pressing unit 331 and the locking unit are elastically abutted, thus facilitating disassembly and reassembly.

[0166] In some embodiments, the dust cup assembly 200 includes a cup body 210. Figures 10-12 ), and the first filter element 220 ( Figure 12The cup body 210 is constructed with a dust cup air duct 211; a first filter element 220 is housed within the dust cup air duct 211, and the first filter element 220 is constructed with a first filter chamber 221, and the side wall of the first filter element 220 is constructed with multiple spaced through holes. When this cleaning device performs a cleaning operation, the mixed fluid is drawn in from the air inlet of the dust cup air duct 211 and filtered through the side wall of the first filter element 220, causing large particles of debris to fall to the outer perimeter of the air inlet channel at the bottom of the cup body 210, thereby achieving primary filtration of the mixed fluid.

[0167] Please see Figure 12 In some embodiments, the bottom wall of the first filter element 220 facing the air inlet of the dust cup duct 211 is a continuous surface. By making the bottom wall of the first filter element 220 facing the air inlet of the dust cup duct 211 a continuous surface, when the mixed fluid is drawn in from the air inlet of the dust cup duct 211, it can only enter the first filter chamber 221 of the first filter element 220 tangentially. This helps to cause large particles of waste to collide with and be blocked by the bottom wall, reducing the possibility of them entering the first filter chamber 221.

[0168] Please see Figure 12 In some embodiments, the dust cup assembly 200 further includes a second filter element 230; the second filter element 230 is housed within the first filter chamber 221 and detachably connected to the first filter element 220, and the second filter element 230 is configured with the second filter chamber 231, and its sidewalls are configured with a plurality of spaced-apart grids 232. When the mixed fluid flows into the first filter chamber 221 through the through holes on the sidewalls of the first filter element 220, the mixed fluid continues to pass through the grids 232 into the second filter element 230, while larger particles of debris collide with the grids 232 and fall downwards, thereby achieving secondary filtration of the mixed fluid. Furthermore, by detachably connecting the second filter element 230 to the first filter element 220, the two can be separated after cleaning, facilitating the user to clean the debris inside and outside the first filter element 220.

[0169] Please see Figure 12 In some embodiments, the bottom wall of the second filter element 230 facing the air inlet of the dust cup duct 211 has multiple through holes. This arrangement allows larger particles of debris to pass through the through holes in the bottom wall of the second filter element 230 as they collide with the grid 232 and move downwards, eventually accumulating at the bottom wall of the first filter element 220.

[0170] In some specific embodiments, the first filter element 220 is tapered towards the air inlet, which makes the bottom wall of the first filter chamber 221 smaller, thus making it easier for larger particles entering the first filter chamber 221 to aggregate together when they collide with the grid 232 and move downwards.

[0171] Please see Figure 12 In some embodiments, the dust cup assembly 200 further includes a third filter element 240; the third filter element 240 is at least partially housed within the second filter chamber 231 and detachably connected to the second filter element 230, and is positioned on the air outlet side of the second filter element 230. By providing the third filter element 240, the mixed gas that has undergone secondary filtration can undergo a third filtration operation. Specifically, the third filter element 240 can be filter cotton. Furthermore, the detachable connection between the third filter element 240 and the second filter element 230 facilitates user replacement and cleaning of debris within the second filter element 230.

[0172] Please see Figure 12 In some embodiments, the dust cup assembly 200 further includes a fourth filter 250, which is installed on the side of the third filter 240 away from the air inlet. The fourth filter 250 can perform a fourth filtration on the mixed gas passing through the third filter 240. Specifically, the fourth filter 250 can be a HEPA filter, thereby filtering out small particles in the mixed gas, such as pollen, smoke, bacteria, and dander.

[0173] Please see Figure 12 In some embodiments, the inner diameter of the dust cup duct 211 near the air inlet is smaller than the inner diameter of the duct near the air outlet. This arrangement results in a smaller duct diameter at the air inlet, effectively ensuring the vacuum level and dust collection capability at the air inlet.

[0174] In some embodiments, a silicone baffle is provided at the top of the air inlet of the dust cup duct 211, which can open or close the air inlet. When the power component is activated, a negative pressure is generated inside the dust cup duct 211, and the baffle rotates relative to the dust cup duct 211, opening the duct. When the power component is deactivated, the internal and external pressures of the dust cup duct 211 are balanced, and the baffle falls back to block the air inlet due to gravity and its own deformation, preventing dust inside the cup 210 from flowing back to the floor brush or outside the cup 210.

[0175] Please see Figure 3In some embodiments, the floor brush assembly 100 includes a first floor brush 110; the first floor brush 110 includes a floor brush housing 111 and a connector 112 that are in communication with each other; the floor brush housing 111 is configured with a cleaning section 1111; and a limiting groove 1112 is configured on the floor brush housing 111; the connector 112 is installed between the floor brush housing 111 and the dust cup assembly 200, and the connector 112 is rotatably connected to the floor brush housing 111; a limiting protrusion 1121 is configured on the connector 112; wherein, when the connector 112 rotates relative to the floor brush housing 111 to a second preset position; specifically, the second preset position is... Figure 3 In the upright position shown, the limiting protrusion 1121 engages with the limiting groove 1112, preventing the brush housing 111 from rotating around the axis of the connector 112. By constructing the limiting groove 1112 on the brush housing 111 and the limiting protrusion 1121 on the connector 112 that mates with the limiting groove 1112, when the first brush 110 of the cleaning device is in the upright position, the engagement of the limiting protrusion 1121 and the limiting groove 1112 prevents the brush housing 111 from rotating around the axis of the connector 112, allowing the first brush 110 to be placed vertically on the ground with good stability.

[0176] In one specific embodiment, the bottom of the cleaning unit 1111 is provided with an air inlet for collecting dirt from the surface to be cleaned, the floor brush housing 111 is provided with a fluid channel inside, and the upper part is provided with an air outlet that communicates with the air inlet of the connector 112. The air outlet of the connector 112 is connected to the air inlet of the dust cup assembly 200 or the air inlet of the extension rod assembly 400.

[0177] In one specific embodiment, the bottom of the floor brush housing 111 is provided with front and rear wheels for support. The four wheels are arranged in a trapezoidal shape, and when the whole machine is placed upright, the center of gravity projection falls into the trapezoid.

[0178] In some embodiments, the air inlet at the cleaning section 1111 at the bottom of the floor brush assembly 100 has a structure that is wide in the middle and narrow at both ends, thereby effectively ensuring the edge vacuum and dust pickup capability at the cleaning section 1111.

[0179] In some embodiments, the first floor brush 110 further includes a second locking member 1122. Figure 3 The second locking member 1122 is rotatably connected to the floor brush housing 111; the second locking member 1122 is constructed with a second locking protrusion 11221. Figure 15 The dust cup assembly 200 has a second locking groove 213 on the side near the floor brush assembly 100. Figure 12When the second locking member 1122 rotates relative to the brush housing 111, the second locking protrusion 11221 can extend into or out of the second locking groove 213. The rotation of the second locking member 1122 relative to the brush housing 111 facilitates the separation of the first brush 110 from the dust cup assembly 200. Furthermore, since the second locking member 1122 is located on the brush housing 111, when it is necessary to separate the dust cup assembly 200 from the first brush 110, the user only needs to press the second locking member 1122 with one hand, which is also convenient. Compared to placing the second locking member 1122 on the dust cup assembly 200, this design eliminates the need for a two-handed operation where one hand presses the second locking member 1122 and the other hand pulls out the first brush 110, making the operation simpler and more convenient.
