Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, and in particular to a floor brush assembly and cleaning equipment. Background Technology

[0002] As people's living standards improve, their demand for floor cleaning is increasing. As an important component of cleaning equipment, the performance of floor brushes directly affects the cleaning effect. Currently, floor brushes on the market require lighting devices to illuminate the surface to be cleaned, especially when used in poor lighting environments, in order to improve the visibility of dust, debris, hair, and other objects on the surface.

[0003] While existing floor brush assemblies are equipped with lighting devices, they suffer from limitations in lighting angle and intensity. The lighting devices can only illuminate a portion of the surface directly in front of the brush, leaving some areas untouched and affecting the cleaning performance of the brush assembly. Furthermore, existing lighting devices are limited by their lighting angle, typically only covering a range of 140° or 160°, resulting in a limited coverage area that fails to meet users' needs for comprehensive cleaning.

[0062] The embodiments of this application are described in detail below, and the embodiments described with reference to the accompanying drawings are exemplary.

[0063] The following is for reference. Figures 1-6 The present application describes a floor brush assembly 100 that can illuminate dust and debris on a surface area to be cleaned located in front of the floor brush assembly 100.

[0064] The term "dust and debris" includes dust, hair, debris, trash, and other unwanted substances that may be located on surfaces to be cleaned, such as floor surfaces, carpet surfaces, or raised surfaces such as countertops, tables, benches, or shelves.

[0065] In some implementations, according to Figures 1 to 5 As shown, the floor brush assembly 100 includes a housing 10, a cleaning component 20, and a developing module 30. The cleaning component 20 is rotatably disposed within the housing 10. The developing module 30 is disposed in the middle of the front side of the housing 10. The developing module 30 includes a light-emitting component 31 and a light-guiding structure 32. The light-guiding structure 32 is used to receive light emitted from the light-emitting component 31 and guide the light to the surface to be cleaned, thereby illuminating dust and debris on the surface to be cleaned. The area includes a sector shape, and the sector shape includes a first edge and a second edge. The sector-shaped illumination area design of this application, by setting the angle between the first edge and the second edge, expands the coverage of the illumination area, enabling good cleaning results even in environments with poor visibility, thus meeting the user's needs.

[0066] Specifically, the housing 10 of the floor brush assembly 100 is used to install the cleaning component 2020 and the developing module 30. The cleaning component 20 can generally be a roller brush with bristles or rubber strips on its surface, or other forms of structures that can clean the surface to be cleaned. In this application, the cleaning component 20 is a cylindrical roller brush. The cleaning component 2020 is rotatably connected to the housing 10. When the cleaning equipment starts working, a negative pressure is formed between the floor brush assembly 100 and the surface to be cleaned by a suction motor or other device installed on it. This draws dust and debris from the surface to be cleaned into the floor brush through the suction port at the bottom of the housing 10 of the floor brush assembly 100, and finally collects it in the dust collection space of the cleaning equipment.

[0067] The developing module 30 is mounted on the floor brush assembly 100 and is used to display dust during cleaning by the cleaning equipment. This allows dust and debris on the surface to be cleaned in front of the floor brush assembly 100 to be visible, enabling the user to observe and perform targeted cleaning. When the light emitted by the developing module 30 shines on the dust and debris on the surface to be cleaned, it creates a reflection of the dust and debris in the direction away from the light. By observing the reflection, the user can easily identify whether there is any residual dust or debris on the surface to be cleaned. The developing module 30 is located in the middle of the front side of the housing 10, meaning that in the horizontal direction, the distance from the developing module 30 to the left and right sides of the housing 10 is approximately the same.

[0068] Furthermore, in one specific embodiment, the developing module 30 can be positioned close to the bottom surface of the floor brush assembly 100 in the vertical direction; in another specific embodiment, the developing module 30 can be positioned close to the top surface of the floor brush assembly 100; of course, the developing module 30 can also be positioned in the middle of the front surface. Thus, the developing module 30 can form a light and shadow area in front of the floor brush assembly 100, causing impurities to be projected onto the ground, forming a very obvious reflection, thereby making the impurities more clearly displayed on the ground, effectively improving the cleaning effect and efficiency, and providing a better user experience.

[0069] The angle between the first edge and the second edge is C, and C satisfies the relationship: greater than 110°.

[0070] In some embodiments of this application, C satisfies the relationship: 120°≤C≤180°.

[0071] In some embodiments of this application, C satisfies the relationship: 130°≤C≤180°.

[0072] In some embodiments of this application, C satisfies the relationship: 140°≤C≤180°.

[0073] In some embodiments of this application, C satisfies the relationship: 150°≤C≤180°.

[0074] In some embodiments of this application, C satisfies the relationship: 160°≤C≤180°.

[0075] In some embodiments of this application, C satisfies the relationship: 170°≤C≤180°.

[0076] In some embodiments of this application, C satisfies the relationship: 178°≤C≤180°.

[0077] In some embodiments of this application, C satisfies the relationship: greater than or equal to 180°.

[0078] In some embodiments of this application, C satisfies the relationship: 180°≤C≤200°.

[0079] In some embodiments of this application, the included angle C can be a value such as 170°, 175°, or a value increasing in increments of 1°, 2°, 3°, 4°, 5°, 6°, 7°, 8°, 9°, and 10° between 160° and 180°. Preferably, C is 180°. In this embodiment, by limiting the included angle C to the above-mentioned range, the range of the light and shadow area is ensured to be large enough to facilitate the development of impurities in front of the floor brush body 100, thereby improving cleaning efficiency and cleaning effect.

[0080] In some examples of this application, the sector includes a first edge and a second edge, with a central axis between the first edge and the second edge. The central axis of the sector shape extends generally in the direction of forward movement of the floor brush assembly 100 during cleaning. Based on the structural design of most floor brushes currently on the market, the most frequently repeated action when a user operates the cleaning device to clean the surface is a push-pull motion in the back-and-forth direction. Therefore, setting the central axis of the fan-shaped area formed by the developing module 30 irradiating the ground to extend in the direction of forward movement of the floor brush assembly 100 during cleaning can cover the area of ​​the surface to be cleaned by the floor brush assembly 100, or the area of ​​the ground to be cleaned, as much as possible, ensuring effective dust detection.

[0081] In some examples of this application, the sector includes a first edge and a second edge, with a central axis between the first and second edges. The central axis of the sector shape is approximately perpendicular to the front edge of the housing 10, and the angle between the front edge of the housing 10 and the first and second edges is approximately equal. To clean debris and dust from corners and other hard-to-reach areas, the front face and two side faces of the floor brush housing 10 are often designed as flat surfaces and perpendicular to each other to match the shape of the corner. Setting the central axis of the sector shape approximately perpendicular to the front edge of the housing 10 provides more comprehensive lighting to these areas when the user is cleaning corners and other hard-to-reach areas.

[0082] Further, the sector includes a first edge and a second edge, with a central axis between the first edge and the second edge. The central axis of the sector shape is approximately perpendicular to the front edge of the cleaning component 20. In one specific embodiment, the cleaning component 20 is a cylindrical roller brush, and the rotation axis of the roller brush is approximately perpendicular to the direction of movement of the floor brush assembly 100 when the cleaning device is working, so that the floor brush can wipe a wider area when passing over the surface to be cleaned, which helps to improve cleaning efficiency. Further, the front end face and two side end faces of the floor brush housing 10 are designed to be flat and perpendicular to each other to match the shape of the corner, in which case the axis of the roller brush is approximately parallel to the front end face of the housing 10. In another embodiment, the front end face of the housing 10 can also be open, that is, the suction port of the floor brush assembly 100 extends from the bottom surface of the housing 10 to the front end face of the housing 10. In this case, the developing module 30 can be set at the edge of the opening on the front end face of the housing 10, or at a position on the top surface of the housing 10 near the front end. This design allows the roller brush to be positioned further forward within the housing 10, reducing blind spots. Since the housing 10 typically has a certain thickness, when the brush assembly 100 performs edge cleaning in the forward direction, the housing 10 can cause areas that the roller brush cannot wipe between the wall edge or other surfaces to be cleaned, affecting the cleaning effect. The open front face of the housing 10 and the forward-positioned roller brush structure can reduce this blind spot, and the roller brush can even clean areas such as baseboards and wall bases.

[0083] In this application, the central axis of the sector shape is approximately perpendicular to the front edge of the housing 10 or the front edge of the cleaning component 20, ensuring a reasonable layout of the lighting components and improving lighting efficiency.

[0084] In some examples of this application, the developing module 30 has one light-emitting element 31. Further, the developing module 30 is an LED lamp bead module. Specifically, the light-emitting element 31 is an LED lamp bead. The developing module 30 can be an LED lamp bead module with multiple light-emitting elements 31 (i.e., multiple LED lamp beads) or an LED lamp bead module with a single light-emitting element 31 (i.e., a single LED lamp bead).

[0085] In other embodiments, the light-emitting element 31 can also be a laser diode. Using a laser diode to illuminate dust and debris on the surface to be cleaned reduces power consumption compared to using an LED, because the electro-optical conversion efficiency of a laser diode is generally significantly higher than that of an LED, requiring less power to be supplied to the laser diode for the same irradiation effect. Furthermore, laser diodes typically generate less heat than LEDs during use, thus eliminating the need for any heat dissipation devices to transfer heat from the laser diode to the surrounding atmosphere.

[0086] In some examples of this application, the formation of the light and shadow area can be achieved by the light-emitting element 31 itself and / or the light having sufficient light intensity, that is, the emission angle of the light-emitting element 31 is large and / or the light intensity is strong, thus ultimately obtaining the light and shadow area.

[0087] In some examples of this application, the light and shadow area can also be formed by a light-emitting element 31 with a certain emission angle and light of a certain intensity, which then passes through the optical surface of the light guide structure 32 and is projected to obtain the light and shadow area. By means of the transformation of the optical surface, a larger area of ​​light and shadow can be obtained. Specifically, the optical surface can be a protrusion or a recess 323 on the light guide structure 32, or it can be a plane.

[0088] according to Figures 3 to 6 As shown, in some examples of this application, considering the range requirements of the light and shadow area, the light guide structure 32 includes a first protrusion 321 and a second protrusion 322. Both the first protrusion 321 and the second protrusion 322 are curved surfaces. The first protrusion 321 and the second protrusion 322 are distributed horizontally. The light emitted by the light-emitting element 31 is emitted through the first protrusion 321 and the second protrusion 322, achieving an illumination angle of approximately 180° in the horizontal direction. Specifically, the light guide structure 32 is a transparent light-transmitting element that can at least change the illumination range of the light emitted by the light-emitting element 31. The light guide assembly is usually exposed on the surface of the housing 10. The first protrusion 321 and the second protrusion 322 of the light guide structure 32 are outwardly protruding lens structures, and the first protrusion 321 and the second protrusion 322 are smoothly connected. A portion of the light emitted by the light-emitting element 31 passes through the first protrusion 321 of the light guide structure 32 and illuminates the surface to be cleaned, forming at least a portion of a sector shape. Another portion of the light emitted by the light-emitting element 31 passes through the second protrusion 322 of the light guide structure 32 and illuminates the surface to be cleaned, also forming at least a portion of a sector shape. The combination of these two portions forms a complete sector shape. In some embodiments, the two portions of the light-emitting element 31 illuminating the surface to be cleaned through the first protrusion 321 and the second protrusion 322 have overlapping areas. In other embodiments, the two portions of the light-emitting element 31 illuminating the surface to be cleaned through the first protrusion 321 and the second protrusion 322 do not have overlapping areas. Preferably, both the first protrusion 321 and the second protrusion 322 are curved surfaces and smoothly connected, resulting in a more uniform brightness distribution in the illuminating area of ​​the light-emitting element 31 illuminating the surface to be cleaned through the light guide structure 32.

[0089] In some examples of this application, the first protrusion 321 and the second protrusion 322 are inclined toward the left and right edges of the floor brush assembly 100, respectively. By inclining the first protrusion 321 and the second protrusion 322 to opposite sides in the horizontal direction, the diffusion effect of the light emitted by the light-emitting element 31 is further optimized, which helps to achieve a larger irradiation range, i.e., a 180° sector shape. The inclination angle of the first protrusion 321 and the second protrusion 322 can be designed and adjusted according to factors such as the selection and quantity of the light-emitting element 31, the position of the developing module 30, and the position of the light-emitting element 31 relative to the light guide structure 32. For example, the light-emitting element 31 is disposed in the middle between the first protrusion 321 and the second protrusion 322 and is directly opposite to the middle. At this time, the light-emitting element 31 can form two irradiation areas on the surface to be cleaned through the first protrusion 321 and the second protrusion 322 that are almost the same, both being approximately 90° fan-shaped areas. At this time, by setting the first protrusion 321 to be tilted at 45° towards the left edge of the brush and the second protrusion 322 to be tilted at 45° towards the right edge of the brush, the irradiation area on the surface to be cleaned can achieve a fan shape of approximately 180°.

[0090] In some examples of this application, a recess 323 is formed in the middle of the light guide structure 32 between the first protrusion 321 and the second protrusion 322. The recess 323 can form a concave lens-like structure between the first protrusion 321 and the second protrusion 322, or in other words, in the middle of the light guide structure 32, which can optimize the scattering effect of the light concentrated in the middle. In some embodiments, a single light-emitting element 31 is provided, and the light-emitting element 31 is positioned directly opposite the recess 323. In this case, since the illumination effect of a single light-emitting element 31 on the front is stronger than that on both sides, the recess 323 can scatter the light emitted in the front, making the brightness distribution of the illumination area formed on the surface to be cleaned more uniform.

[0091] In some examples of this application, at least two light-emitting elements 31 are provided. By providing two light-emitting elements 31 instead of one, on the one hand, two light-emitting elements 31 can directly combine to form an illumination range with a larger coverage angle compared to a single light-emitting element 31. Therefore, there is no need to provide an additional special light guide structure 32 for auxiliary light guiding, and a more uniform illumination effect can be achieved. On the other hand, under the same illumination brightness, the heat generated by two light-emitting elements 31 is more dispersed than the heat generated by a single light-emitting element 31, thus making heat dissipation easier. In one specific embodiment, the light guide structure 32 includes a first protrusion 321 and a second protrusion 322, and the first protrusion 321 and the second protrusion 322 each correspond to at least one light-emitting element 31. Further, the illumination directions of the first light-emitting element 31 and the second light-emitting element 31 are arranged at an angle and are respectively directly opposite the first protrusion 321 and the second protrusion 322. This arrangement can reduce the overlap of the light emitted by the first light-emitting element 31 and the second light-emitting element 31, further optimizing the uniformity of the brightness distribution in the illumination area.

[0092] To facilitate clear visualization of dust and debris on the surface to be cleaned, the developing module 30 generates either colored or transparent light. Preferably, the light generated by the developing module 30 is green, as green light has a longer wavelength and can be viewed from a greater distance. Additionally, green light can alleviate eye strain to some extent. However, the color of the light emitted by the developing module 30 may include, but is not limited to, green; it can also be white, red, yellow, etc., and this application does not impose any specific limitations on this.

[0093] In some examples of this application, the light guide structure 32 includes a first protrusion 321, a second protrusion 322, and a recess 323. The first protrusion 321, the second protrusion 322, and the recess 323 are all curved surfaces. The light-emitting element 31 can form a generally conical light beam in front of the light guide structure 32. In the horizontal direction parallel to the surface to be cleaned, the cone angle of the light beam ranges from 170° to 180°. This cone angle is the angle formed by the aforementioned sector shape.

[0094] In some embodiments, the cone angle E of the light beam ranges from 0° to 50° in the vertical direction perpendicular to the surface to be cleaned. It should be noted that in this specification, "approximately" can be understood as close to, approximately, or within a predetermined range from the target value.

[0095] In some embodiments, the cone angle E of the light beam ranges from 5° to 35° in the vertical direction perpendicular to the surface to be cleaned.

[0096] In some embodiments, the cone angle E of the beam is in the range of 10° to 25° in the vertical direction perpendicular to the surface to be cleaned.

[0097] In some embodiments, the light guide structure 32 is positioned near the top of the housing 10 of the floor brush assembly 100. The light guide structure 32 is tilted towards the surface to be cleaned, such that the angle F between the central axis of the light beam and the ground in the vertical direction perpendicular to the surface to be cleaned ranges from 10° to 30°. In practice, the user can select a light guide structure 32 with a corresponding cone angle E based on the angle between the central axis of the light beam and the ground after the light guide structure 32 is tilted. Alternatively, the user can design the position and tilt angle of the light guide structure 32 on the housing 10 based on the selected light guide structure 32, so that the divergence angle of the light beam emitted by the light-emitting element 31 in the developing module 30 through the light guide structure 32 in the vertical plane is small. This shallow-angle lighting improves the user's visual detection of dust and debris on the surface to be cleaned. Visually, the light scattered by the dust and debris appears brighter than the light reflected from the surface, and the relatively long shadows cast behind the dust and debris create a clear contrast with the relatively brightly lit dust and debris. This lighting effect effectively helps the user identify the dust and debris on the surface to be cleaned and increases the likelihood that the brush assembly 100 will capture the dust and debris as it moves back and forth on the surface, reducing the time spent cleaning the surface and thus reducing power consumption.

[0098] In some embodiments of this application, the region further includes a columnar region formed in front of the fan-shaped region by an arc-shaped central portion protruding from the fan-shaped region. Specifically, in one embodiment, the developing module 30 is an LED lamp bead module with a single light-emitting element 31, i.e., a single LED lamp bead. The light guide structure 32 has a recess 323 in the middle position directly opposite the light-emitting element 31, and the wall thickness of the light guide structure 32 is relatively thin at this position, so that the light emitted by the light-emitting element 31 through the recess 323 can reach a farther position on the surface to be cleaned. In another embodiment, the developing module 30 is an LED lamp bead module with two light-emitting elements 31, i.e., two LED lamp beads. By adjusting the relative position and angle of the two light-emitting elements 31, the light emitted by the two light-emitting elements 31 forms an overlapping area at the middle position. Combined with the recess 323 and thin wall structure on the light guide structure 32, the irradiation area includes a columnar region formed in front of the fan-shaped region by an arc-shaped central portion protruding from the fan-shaped region. This setup allows the developing module 30 to irradiate a wider area along the path of the cleaning brush during the cleaning process, while ensuring the necessary irradiation range. This makes it easier for users to anticipate whether the area ahead needs to be cleaned.

[0099] In some implementations, such as Figure 2 and 4As shown, the floor brush assembly 100 includes: a housing 10; a cleaning component 20, which is rotatably disposed within the housing 10; and a developing module 30, which is disposed in the middle of the front side of the housing 10. The developing module 30 includes: a light-emitting component 31 and a light-guiding structure 32. The light-guiding structure 32 is used to receive light emitted from the light-emitting component 31 and guide the light to the surface to be cleaned, thereby illuminating the dust and debris on the surface to be cleaned. The area includes a sector shape, which includes a first edge and a second edge. The angle between the first edge and the second edge and the front edge of the housing 10 is B, where B is an acute angle not greater than 30°.

[0100] In some examples of this application, B satisfies the relationship: 0°≤B≤20°.

[0101] In some examples of this application, B satisfies the relationship: 0°≤B≤10°.

[0102] In some examples of this application, B satisfies the relationship: 0°≤B≤5°.

[0103] In some examples of this application, B satisfies the relationship: 1°≤B≤5°.

[0104] Furthermore, the developing module 30 irradiates the dust and debris on the surface area to be cleaned. The area includes a sector shape, which includes a first edge and a second edge. The included angle between the first edge and the second edge is C, and C satisfies the relationship: greater than or equal to 160°.

[0105] In some embodiments of this application, C satisfies the relationship: 160°≤C≤180°.

[0106] In some embodiments of this application, C satisfies the relationship: 170°≤C≤180°.

[0107] In some embodiments of this application, C satisfies the relationship: 178°≤C≤180°.

[0108] In some embodiments of this application, C satisfies the relationship: greater than or equal to 180°.

[0109] In one embodiment, the floor brush assembly 100 of this application includes: a housing 10; a cleaning component 20, which is rotatably disposed within the housing 10; and a developing module 30, which is disposed in the central region of the central axis on the front side of the housing 10. The developing module 30 includes a light-emitting component 31, and the light emitted by the light-emitting component 31 is projected onto the surface to be cleaned in a sector shape. The sector shape includes a first edge and a second edge, and the included angle between the first edge and the second edge is C, where C satisfies the relationship: 140°≤C≤180°.

[0110] In some embodiments of this application, C satisfies the relationship: 150°≤C≤180°.

[0111] In some embodiments of this application, C satisfies the relationship: 160°≤C≤180°.

[0112] In some embodiments of this application, C satisfies the relationship: 170°≤C≤180°.

[0113] In some embodiments of this application, C satisfies the relationship: 180°≤C≤190°.

[0114] In some embodiments, the cleaning device of this application includes the floor brush assembly 100 described above.

[0115] In some examples of this application, a photosensitive element and a controller are also included. The photosensitive element is used to detect the lighting conditions of the cleaning environment, and the controller is used to control the irradiation brightness of the developing module 30 according to the lighting conditions detected by the photosensitive element. By setting a photosensitive element and a controller, this application realizes the function of dynamically adjusting the irradiation brightness of the developing module 30 according to the lighting conditions of the cleaning environment. This overcomes the shortcomings of traditional fixed brightness or manual adjustment modes that cannot match dynamic lighting scenes, effectively reducing the omission rate of dark area cleaning and improving the cleaning efficiency of bright areas.

[0116] In some examples of this application, the photosensitive element is disposed on the floor brush assembly 100. This avoids the problem that when the user extends the floor brush to a low-lying area or an area where the ambient light is blocked for cleaning in a well-lit environment, the developing module 30 reduces the brightness, causing the user to not be able to see the cleaning situation in the dark in a well-lit environment.

[0117] According to some alternative embodiments of this application, in combination with Figure 5As shown, the distance H between the center of the light-emitting element 31 and the surface to be cleaned in the vertical direction satisfies the relationship: 2mm ≤ H ≤ 20mm. Specifically, in the vertical direction, the developing module 30 can be positioned close to the bottom surface of the housing 10 of the floor brush assembly 100, or close to the top surface of the housing 10 of the floor brush assembly 100, or it can be positioned in the middle of the front surface of the housing 10. Based on the position of the developing module 30 in the vertical direction of the housing 10, the tilt angle of the developing module 30 and the illumination angle of the developing module 30 in the vertical direction are set so that the distance between the center of the light-emitting element 31 and the surface to be cleaned is small. This allows the light emitted by the light-emitting element 31 to be closer to the dust and debris on the surface to be cleaned, and also allows the illumination angle of the developing module 30 to be shallower. This makes it easier for the user to identify the dust and debris on the surface to be cleaned, increases the likelihood that the dust and debris will be captured by the floor brush assembly 100 when it moves back and forth on the surface to be cleaned, reduces the time spent cleaning the surface to be cleaned, and thus reduces power consumption. When the local brush component 100 moves on the surface to be cleaned, the developing module 30 provides debris illumination. This setting, based on a more obvious visual design of dust and debris, makes it easier for users to determine the path selection and pushing frequency. For example, if there is too much dust and debris in front, users can push slower to allow the dust and debris to be thoroughly cleaned. For stubborn dust and debris, users can also clean repeatedly to ensure cleaning effect.

[0118] According to some optional embodiments of this application, the light guide structure 32 is a light guide structure 32 that receives emitted light and guides the light beam to the surface to be cleaned. Specifically, the light guide structure 32 has excellent light-gathering ability, long range, and strong penetration. By receiving the light emitted from the light-emitting element 31 and guiding the light to the surface to be cleaned where the floor brush assembly 100 is placed, the light guide structure 32 can illuminate the dust and debris on the flat surface to be cleaned more clearly and brightly, thereby increasing the possibility that the dust and debris will be captured by the floor brush assembly 100 when it moves back and forth on the surface to be cleaned, reducing the time spent cleaning the surface to be cleaned, and thus reducing power consumption.

[0119] The cleaning device according to the fourth aspect of this application includes the floor brush assembly 100 described above. Specifically, the cleaning device having the floor brush assembly 100 can improve the visibility of dust and debris on the surface to be cleaned in environments with poor visibility, thereby achieving a better cleaning effect.

[0120] According to some alternative embodiments of this application, the cleaning equipment is a handheld cleaning device or a floor scrubber with wet mopping function. Specifically, handheld cleaning devices and floor scrubbers have a larger working range, are more convenient, and can be applied to more cleaning environments.

[0121] According to some optional embodiments of this application, the cleaning device also includes a main unit connected to the housing 10, and a battery for power supply is disposed within the main unit. Thus, the cleaning device can be a cordless vacuum cleaner or a cordless floor scrubber. Specifically, the main unit and housing 10 are interconnected as a single unit, and the main unit contains a battery for providing power to the cleaning device when performing cleaning and lighting functions, which can improve the structural stability and design rationality of the cleaning device.

[0122] According to some optional embodiments of this application, the cleaning device further includes a main unit connected to the housing 10. The main unit contains a power unit and a controller, both of which are electrically connected to the controller. Specifically, the main unit and housing 10 are interconnected as a single unit. The main unit contains a power unit that drives the cleaning device to perform cleaning operations and a controller that controls the cleaning device to perform cleaning functions according to user needs. Both the power unit and the light-emitting element 31 are connected to the controller via electrical signals, which improves the response speed and accuracy of the power unit and the light-emitting element 31. The power unit can be a motor.

[0123] According to one specific embodiment of this application, when the power unit of the cleaning equipment is turned on, the controller is arranged to activate the developing module 30. For example, the controller can provide a constant power to the developing module 30 so that the intensity of the light emitted from the developing module 30 remains constant when the motor is turned on. Alternatively, the controller can change the power supplied to the developing module 30 over time, so that the output light power of the developing module 30 changes over time.

[0124] For example, the power supplied to the developing module 30 by the controller can be gradually varied, or it can be gradually varied. Specifically, the power supplied to the developing module 30 gradually increases from the time the power unit is turned on until the maximum supply power is reached.

[0125] For example, the maximum optical output power of the light-emitting element 31 is 10mW in this embodiment. Within one second of the motor being turned on, the power supply to the developing module 30 can increase at a constant rate or vary over time. Specifically, when the motor is turned on, the power increase rate can be relatively low and gradually increase over time. Furthermore, in this embodiment, the light-emitting element 31 is a laser diode. The controller is connected to the mating terminal 50 of the floor brush assembly 100 via one or more wires, and then connected to the developing module 30 via wires within the mating terminal 50.

[0126] According to another specific embodiment of this application, the controller can delay supplying power to the developing module 30 for a period of time after the motor has been turned on. This relatively low or no power supply period to the developing module 30 can accommodate the time when the user positions the floor brush assembly 100 on the work surface after turning on the motor, and thus accommodate the time when the developing module 30 does not project light onto the surface to be cleaned.

[0127] Optionally, when the motor is turned off, the controller is arranged to immediately stop supplying power to the developing module 30. The controller may be arranged to adjust the power supply to the developing module 30 based on changes in the state of the floor brush assembly 100 or the cleaning equipment when the motor is on. For example, the controller may pause, reduce, or otherwise adjust the power supply to the developing module 30 based on the orientation of the floor brush assembly 100 or the cleaning equipment. One of the floor brush assembly 100 or the cleaning equipment may include a sensor that outputs a signal to the controller that varies according to its orientation, and the controller may be arranged to adjust the power supply to the developing module 30 based on the output from the sensor.

[0128] Furthermore, if the floor brush assembly 100 is lifted off the work surface, the controller can adjust the power supply to the developing module 30. The floor brush assembly 100 may include sensors, such as steering wheels that detect whether the floor brush assembly 100 has been lifted off the work surface, or sensors that detect air pressure within the suction chamber, and the controller can be arranged to adjust the power supply to the developing module 30 based on signals received from these sensors. When the behavior of the cleaning equipment changes, this change can indicate an interruption of the cleaning process, which can reduce the power consumption of the developing module 30, for example, by relocating the cleaning equipment to another location in the home, thus saving battery energy.

[0129] The controller is also configured to stop supplying power to the controller when the motor is turned off by the user or when the battery is depleted, which will also cause the light-emitting element 31 to turn off, thereby achieving the effect of timely and effective shutdown of the light-emitting element 31.

[0130] Although embodiments of this application have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of this application, the scope of which is defined by the claims and their equivalents.
