[0060] With the development of science and technology, cleaning equipment is widely used. Users can use cleaning equipment to clean floors, carpets, and other areas that need cleaning. However, during the cleaning process, due to dim lighting, users cannot identify whether the surface to be cleaned has been cleaned completely or whether the stains have been removed. To observe the cleaning status, a light source component can be installed on the brush head of the cleaning equipment to illuminate the area in front of the equipment. However, the coverage of the light source component in related technologies is limited and cannot illuminate the cleaning area. In dim lighting conditions, some corners are difficult to see, resulting in cleaning blind spots. The brush head, cleaning equipment, and cleaning system provided in this application embodiment can improve the above problems. The brush head, cleaning equipment, and cleaning system provided in this application embodiment can increase the illuminated area, minimize cleaning blind spots, and improve the cleaning effect of the cleaning equipment.
[0061] This application is described below with reference to the accompanying drawings and specific embodiments:
[0062] Figure 1 This illustration shows a first-view structural schematic diagram of the cleaning device 10 provided in an embodiment of this application. Figure 2 It shows Figure 1 The sectional view at point AA, as shown Figure 1 and Figure 2 As shown, the cleaning device 10 can be a floor scrubber, a vacuum cleaner, etc. The brush head 100 provided in this embodiment can increase the illumination area, minimize cleaning dead corners, and improve the cleaning effect of the cleaning device 10.
[0063] Figure 3 It shows Figure 2 A magnified view of a section at point I. Figure 4 This paper shows a schematic diagram of the structure of the light guide component 2 provided in an embodiment of this application. Figure 5 A schematic diagram of the structure of the light guide 130 of the light guide assembly 2 provided in this application embodiment is shown, as follows: Figure 3 , Figure 4 , Figure 5As shown, the light guide assembly 2 provided in this application embodiment can be applied to the brush head 100 and also to the cleaning device 10. In this application embodiment, the light guide assembly 2 includes a light guide 130 and a light source 140. The light guide 130 includes a light emitting part 132 and a light guiding part 134 connected together. The light guide 130 guides the light emitted by the light source 140. The length of the light guiding part 134 in the first direction X is greater than the length of the light guiding part 134 in the second direction Y, and the length of the light guiding part 134 in the third direction Z is greater than the length of the light guiding part 134 in the fourth direction W. The first direction X is the forward direction of the cleaning device 10, the second direction Y is perpendicular to the first direction X and parallel to the surface to be cleaned, the third direction Z is parallel to the surface to be cleaned, and the third direction Z, the fourth direction W, and the axial direction V of the light guide part 134 are perpendicular to each other.
[0064] Wherein, the length of the light guide portion 134 in the first direction X is as follows Figure 6 and Figure 8 As shown in L1, the length Y of the light guide portion 134 in the second direction is as follows: Figure 6 and Figure 8 As shown in L2, the length of the light guide 134 in the third direction Z is as follows: Figure 7 and Figure 9 As shown in L3, the length of the light guide 134 in the fourth direction W is as follows: Figure 7 and Figure 9 As shown in L4.
[0065] The light guide component 100 can be directly applied to the cleaning device 10. The first direction X is the forward direction of the cleaning device 10, and the second direction Y is parallel to the surface to be cleaned. During the cleaning process of the cleaning device 10 cleaning the surface to be cleaned, the cleaning part 120 of the cleaning device 10 contacts the surface to be cleaned. The second direction Y being parallel to the surface to be cleaned means that almost the entire cleaning surface of the cleaning part 120 of the cleaning device 10 is in contact with the surface to be cleaned, that is, when the surface to be cleaned is flat, the second direction Y is parallel to the surface to be cleaned. If the cleaning part of the cleaning device is a roller brush, then the surface in contact with the surface to be cleaned is parallel to the axial direction of the roller brush. That is, if the cleaning part is a roller brush, then the second direction Y is perpendicular to the first direction X and parallel to the axial direction of the cleaning part, that is, parallel to the surface to be cleaned means parallel to the axial direction of the cleaning part 120. If the cleaning part is a mop, the cleaning surface of the cleaning device is also the surface in contact with the surface to be cleaned. Since the cleaning surface of the mop has felt and is not necessarily flat, the cleaning surface of the cleaning device can be the fixed surface of the mop. For ease of description, the cleaning part is a roller brush in the embodiments of this application.
[0066] Since the length of the light guide portion 130 in the first direction X is greater than the length of the light guide portion in the second direction Y, it means that the light guide portion 130 is roughly elongated along the first direction X, the axial direction V of the light guide portion 134 is also roughly along the first direction X, the third direction Z is parallel to the surface to be cleaned, and the fourth direction W is perpendicular to the third direction Z and the axial direction V of the light guide portion 134, that is, the fourth direction W is a vertical direction.
[0067] The cleaning section 120 is roughly cylindrical. The length of the cleaning section 120 in the axial direction is the cleaning area of the cleaning section 120. In order to reduce the cleaning dead corners of the cleaning section 120, during the cleaning process, the illumination area of the light emitting section 132 in front of the cleaning section 120 in the third direction Z should be as large as possible, so that the illumination area of the light emitting section 132 can cover the cleaning area of the cleaning section 120 as much as possible.
[0068] The width of the light guide section 134 in the third direction Z determines the width of the illumination area of the light emitting section 132 in the third direction Z, and the width of the light guide section 134 in the fourth direction W determines the width of the illumination area of the light emitting section 132 in the forward direction of the cleaning device 10. Since the third direction Z is approximately parallel to the axis of the cleaning section (it should be noted that when the angle between the third direction Z and the axis of the cleaning section is less than 10 degrees, the third direction Z can be considered to be approximately parallel to the axis of the cleaning section), the wider the width of the light guide section 134 in the third direction Z, the wider the cleaning area of the cleaning section 120 illuminated by the light emitting section 132; the narrower the width of the light guide section 134 in the third direction Z, the narrower the cleaning area of the cleaning section 120 illuminated by the light guide section 134. The wider the width of the light guide 134 in the fourth direction W, the wider the illumination area of the light emitting part 132 in front of the cleaning part 120; conversely, the narrower the width of the light guide 134 in the fourth direction W, the narrower the illumination area of the light emitting part 132 in front of the cleaning part 120.
[0069] The length of the light guide 134 in the third direction Z is greater than the length of the light guide 134 in the fourth direction W. This indicates that the width of the light guide 134 in the third direction Z is wider, which makes the illumination area of the light emitting part 132 in the third direction Z also wider. Since the third direction Z is in the same direction as the axial direction of the cleaning part 120, the illumination of the light emitting part 132 in the cleaning area of the cleaning part 120 is wide enough, which can reduce the cleaning dead corners of the cleaning part 120 and improve the cleaning effect.
[0070] In some embodiments, if the ratio of the length of the light guide portion 134 in the third direction Z to the length of the light guide portion 134 in the fourth direction W is greater than 1 and less than 5, it indicates that the width of the light guide portion 134 in the third direction Z is relatively wide, resulting in a wider illumination area of the light emitting portion 132 in the third direction Z. Since the third direction Z is approximately parallel to the axial direction of the cleaning portion 120, the illumination of the light emitting portion 132 in the cleaning area of the cleaning portion 120 is sufficiently wide, which can reduce the cleaning dead angles of the cleaning portion 120 and improve the cleaning effect.
[0071] Furthermore, the presence of a light source in front of the cleaning unit 120 illuminates the cleaning area, minimizing the risk of collisions or slips when operating in dimly lit environments. The lighting also allows users to more easily observe the overall cleaning status, enhancing ease of operation. The lighting design also improves the product's appearance, giving it a more technological and modern feel. This lighting enables the cleaning equipment 10 to be used in low-light conditions such as at night and in basements, expanding its application scenarios and increasing its usability.
[0072] In some embodiments, the ratio of the length of the light guide portion 134 in the third direction Z to the length of the light guide portion 134 in the fourth direction W can be 1, 1.5, 2, 2.5, 3, 3.5, 4, 4.5, 5, etc., and the specific ratio is not limited.
[0073] In some embodiments, the ratio of the length of the light guide portion 134 in the third direction Z to the length of the light guide portion 134 in the fourth direction W is greater than 1.5 and less than 2.5, indicating that the length of the light guide portion 134 in the third direction Z is greater than the length of the light guide portion 134 in the fourth direction W, but the length of the light guide portion 134 in the third direction Z is not much different from the length of the light guide portion 134 in the fourth direction W, so that the illumination width on the axis of the cleaning portion 120 can be guaranteed, and the illumination width in the first direction X can also be increased, thereby increasing the illumination area of the entire light emitting portion 132.
[0074] In some embodiments, the light guide portion 134 and the light emitting portion 132 can be integrally formed, which can reduce the manufacturing process of the entire light guide 130. The light guide 130 can be made of plastic, specifically, polycarbonate (PC).
[0075] In some embodiments, the length of the light guide portion 134 along the third direction Z is 6mm-10mm. The length of the light guide portion 134 along the third direction Z can be 6mm, 6.5mm, 7mm, 7.5mm, 8mm, 8.5mm, 9mm, 9.5mm, 10mm, etc., and the specific value of the first light guide portion 134a is not limited. The length of the light guide portion 134 along the third direction Z is 6mm-10mm, which ensures that the light-emitting portion 132 provides sufficiently wide illumination in the cleaning area of the cleaning portion 120, reducing cleaning dead zones of the cleaning cloth and improving the cleaning effect.
[0076] In some embodiments, the length of the light guide portion 134 along the fourth direction W is 2mm-6mm. The length of the light guide portion 134 along the fourth direction W can be 2mm, 2.5mm, 3mm, 3.5mm, 4mm, 4.5mm, 5mm, 5.5mm, 6mm, etc. The length of the light guide portion 134 along the fourth direction W of 2mm-6mm can ensure that the illumination area of the light-guiding portion 132 in front of the cleaning portion 120 has a certain width, allowing the user to observe the situation in front of the cleaning portion 120, reducing cleaning dead angles, and improving the cleaning effect.
[0077] Figure 6 A schematic diagram of the structure of the light guide 130 provided in some embodiments from a second perspective is shown. Figure 7 It shows Figure 6 A magnified view of the area at CC, as shown below. Figure 6 and Figure 7 As shown, in some embodiments, the light guide portion 134 forms a cross section in the plane containing the third direction Z and the fourth direction W, and the profile of the cross section is at least partially arc-shaped.
[0078] Since the third direction Z and the fourth direction W are perpendicular to each other and both perpendicular to the axial direction V of the light guide 134, the plane containing the third direction Z and the fourth direction W is also perpendicular to the axial direction V of the light guide 134. Therefore, the cross-section of the light guide 134 in the plane containing the third direction Z and the fourth direction W is perpendicular to the axial direction V of the light guide 134. The profile of the cross-section is at least partially arc-shaped; it can be that only part of the profile is arc-shaped, while the remaining part is of another shape. Alternatively, the entire profile of the cross-section can be arc-shaped.
[0079] The profile of the cross section is at least partially arc-shaped, so that during the transmission of light inside the light guide 134, the arc-shaped light guide 134 can change the direction of the light inside the light guide 134, so that the light can be transmitted in different directions inside the light guide 134, and then dispersed at different positions after the light is emitted from the light emitting part 132, which can also improve the illumination area of the entire light emitting part 132 to a certain extent.
[0080] Figure 8A structural schematic diagram of the light guide 130 provided in some other embodiments is shown. Figure 9 It shows Figure 8 A magnified view of the area at DD, as shown below. Figures 6-9 As shown, in some embodiments, the light guide portion 134 is rectangular in shape in the plane containing the third direction Z and the fourth direction W (e.g., Figure 8 and Figure 9 As shown), elliptical (as shown) Figure 6 and Figure 7 (as shown), at least one of the following shapes: triangle, trapezoid, and frustum.
[0081] The shape of the light guide 134 refers to the shape of its cross-section in the plane containing the third direction Z and the fourth direction W. If the light guide 134 is rectangular, its long side is along the third direction Z and its wide side is along the fourth direction W. If the light guide 134 is elliptical, its major axis is along the third direction Z and its minor axis is along the fourth direction W. If the light guide 134 is trapezoidal, its third direction Z is the direction of its long and short sides, and its fourth direction W is the direction of its height. If the light guide 134 is triangular, its third direction Z is the direction of its longest side. If the light guide 134 is frustum-shaped, its third direction Z is the direction of its longest length.
[0082] When the light guide 134 is elliptical in shape, the arc-shaped outline of the light guide 134 allows the light to change its direction within the light guide 134 during its transmission. This enables the light to be transmitted in different directions within the light guide 134, and thus disperses the light at different locations after it exits the light emitting part 132, thereby increasing the illumination area of the entire light emitting part 132 to a certain extent.
[0083] In some embodiments, the axis of the light guide portion 134 intersects the first direction X. This indicates that the direction in which the axis of the light guide portion 134 is located (the axial direction V of the light guide portion 134) intersects the first direction X.
[0084] Wherein, the first direction X is the forward direction of the cleaning device 10. The axis of the light guide 134 intersects with the first direction X, which means that the light guide 134 is inclined relative to the first direction X, so that the light guide 134 and the light source 140 have a certain angle, so that the light guide 134 can integrate the light emitted from the light source 140, and the light can be concentrated.
[0085] like Figure 8As shown, in some embodiments, the angle α between the light guide portion 134 and the first direction X is 0°~5°. If the cleaning angle of the light guide portion 134 in the first direction X is too large, the light rays between different light guide portions 134 will cross, making the illumination area too concentrated. The angle α between the light guide portion 134 and the first direction X can be set to 0°~5°, so that the light can be concentrated towards the nozzle 114 while maintaining the width in the third direction Z as much as possible, resulting in a larger illumination area and thus improving the cleaning effect.
[0086] In some embodiments, the distance between the plurality of light guides 134 gradually decreases along the first direction X, so that the plurality of light guides 134 can be arranged in a direction closer to the nozzle 114, so that the light can more easily illuminate the landing point of the water, allowing the user to observe the water spray path and cleaning process, thereby improving the ease of operation.
[0087] In some embodiments, the light guide 130 further includes a connecting portion 136, which connects a plurality of light guide portions 134. For ease of description, when there are two light guide portions 134, the two light guide portions 134 are respectively a first light guide portion 134a and a second light guide portion 134b. The light guide 130 connects the two light guide portions 134 (connecting the first light guide portion 134a and the second light guide portion 134b), which can improve the strength of the light guide 130. This enhances the torsional resistance of the light guide 130 without affecting the light effect.
[0088] Figure 10 It shows Figure 5 Side view of the central light guide component, as shown Figure 10 As shown, in some embodiments, the light-emitting part 132 has an emission surface 1322, which can be a plane and can be perpendicular to the emitted light, so that no new refraction occurs during the process of the light entering the air from the light-emitting part 132, thereby reducing the loss of light.
[0089] The emitting surface 1322 has a certain angle with the surface to be cleaned. The angle b between the emitting surface 1322 and the surface to be cleaned is 50°~90°, so that the light emitted by the emitting surface 13222 can shine forward and downward, illuminating the surface to be cleaned in front, thereby improving the cleaning effect.
[0090] In some embodiments, the light guide portion 134 includes a first light guide segment 1342 and a second light guide segment 1344. The first light guide segment 1342 connects the second light guide segment 1344 and the light emitting portion 132. The first light guide segment 1342 is perpendicular to the emission surface 1322 of the light emitting portion 134, so that no refraction occurs when light enters from the first light guide segment 1344 and exits into the light emitting portion 134, thus ensuring the accuracy of the illumination position.
[0091] Figure 11 It shows Figure 1 A partial structural diagram of the cleaning equipment 10 in the diagram. Figure 12 It shows Figure 11 A magnified view of a section at point II. Figure 13 A side view of the light guide is shown, as follows. Figure 11 , Figure 12 and Figure 13 As shown, in some embodiments, the brush head 100 further includes a collimator 150, which is disposed between the light source 140 and the light guide 134. The collimator 150 can organize and converge the light emitted from the light source 140, allowing the light to converge to the light guide 134, so that the light can pass through the light guide 134 and then illuminate the front of the cleaning section 120 from the light emission section 132.
[0092] Figure 14 A structural schematic diagram of the collimator 150 from a first-view perspective is shown. Figure 15 A structural schematic diagram of the collimator 150 from a second perspective is shown, as follows. Figure 14 and Figure 15 As shown, in some embodiments, the collimator 150 has a light-incident surface 151 and a light-exit surface 152 disposed opposite to each other. The light-incident surface 151 is disposed near the light source 140, and the light-exit surface 152 is disposed near the light guide portion 134. The light-incident surface 151 is curved. The curved surface of the light-incident surface 151 allows for more spatial orientations, enabling as much light emitted from the light source 140 as possible to pass through the light-incident surface 151 and enter the light guide portion 134, thereby improving illumination.
[0093] In some embodiments, the collimator 150 has a mounting groove 153, and the light-incident surface 151 is disposed within the mounting groove 153. Since the light-incident surface 151 is curved, and the light-incident surface 151 is disposed within the mounting groove 153, the mounting groove 153 can protect the light-incident surface 151, reducing the amount of dust and other impurities falling onto the light-incident surface 151 and affecting the light-focusing effect of the light-incident surface 151.
[0094] In some other embodiments, the mounting groove 153 may not be provided on the collimator 150. By not placing the collimator 150 within the mounting groove 153, the light incident area of the light incident surface 151 of the collimator 153 can be increased, thereby increasing the light intensity. Of course, the specific method is not limited.
[0095] In some embodiments, the collimator 150 includes a connecting plate 154, a first collimation portion 155, and a second collimation portion 156, wherein the first collimation portion 155 and the second collimation portion 156 are disposed on the connecting plate 154.
[0096] The light guide portion 134 includes a first light guide portion 134a and a second light guide portion 134b. A first collimation portion 155 is disposed between the first light guide portion 134a and the light source 140, and a second collimation portion 156 is disposed between the second light guide portion 134b and the light source 140.
[0097] Since there are two light guides 134, there are also two collimating parts. The first collimating part 155 and the second collimating part 156 are both provided with an incident surface 151 (the arrangement of the incident surface 151 is as described above and will not be repeated) and an exit surface 152. The incident surface 151 of the first collimating part 155 is located near the light source 140, and the exit surface 152 of the first collimating part 155 is located near the first light guide 134a. The incident surface 151 of the second collimating part 156 is located near the light source 140, and the exit surface 152 of the second collimating part 156 is located near the second light guide 134b.
[0098] In some embodiments, the first collimating portion 155 and the second collimating portion 156 are arranged at intervals. This can reduce the risk of crosstalk between the first collimating portion 155 and the second collimating portion 156, and can maximize the uniformity of illumination of the first light guide portion 134a and the second light guide portion 134b.
[0099] It should be noted that in some other embodiments, the collimator 150 may not include two collimating parts, and may only have one long light-incident surface 151 and light-exit surface 152 corresponding to two light guides 134 (first light guide 134a and second light guide 134b), that is, there is only one light-incident surface 151 and one light-exit surface 152. The light-incident surface 151 is set close to the light source 140, and the light-exit surface 152 is set corresponding to the two light guides 134 (first light guide 134a and second light guide 134b).
[0100] In some embodiments, a first mounting hole 1551 is provided on the first collimating portion 155, and a second mounting hole 1561 is provided on the second collimating portion 156. The first mounting hole 1551 and the second mounting hole 1561 can be injection molding holes.
[0101] Since the first collimating part 155 and the second collimating part 156 are spaced apart, there is a groove 157 between the first collimating part 155 and the second collimating part 156. The groove 157 can cooperate with the housing 110 to install the entire collimating member 150 on the housing 110.
[0102] In summary, in the brush head 100 provided in this application embodiment, the ratio of the length of the light guide portion 134 in the third direction Z to the length of the light guide portion 134 in the fourth direction W is greater than 1 and less than 5. This indicates that the width of the light guide portion 134 in the third direction Z is relatively wide, resulting in a wider illumination area of the light emitting portion 132 in the third direction Z. Since the third direction Z is in the same direction as the axial direction of the cleaning portion 120, the illumination of the light emitting portion 132 in the cleaning area of the cleaning portion 120 is sufficiently wide, which can reduce the cleaning dead corners of the cleaning cloth and improve the cleaning effect.
[0103] Figure 16 This diagram illustrates a second-view structural schematic of the cleaning device 10 provided in an embodiment of this application. Based on the same inventive concept, this application also provides a brush head 100, including a housing 110 and the aforementioned light guide assembly 2, wherein the light guide assembly 2 is mounted on the housing 110.
[0104] The housing 110 is the basic component of the entire brush head 100. It provides a base for the installation of structures such as the cleaning part 120, the light guide 130, and the light source 140. Structures such as the cleaning part 120, the light guide 130, and the light source 140 can be installed on the housing 110, so that the housing 110 can protect structures such as the cleaning part 120, the light guide 130, and the light source 140.
[0105] The cleaning section 120 is installed inside the mounting cavity 112 and partially protrudes outside the mounting cavity 112, allowing the cleaning section 120 to clean the surface to be cleaned. The light source 140 is also disposed inside the mounting cavity 112, and the light source 140 is disposed opposite to the light guide section 134 of the light guide member 130, so that the light emitted by the light source 140 can be guided through the light guide section 134 and the light emitting section 132 to the front of the cleaning section 120, illuminating the area in front of the cleaning section 120.
[0106] In some embodiments, the housing 110 is provided with a nozzle 114 for spraying steam or liquid; the light-emitting part 132 is close to the nozzle 114, which means that the distance between the light-emitting part 132 and the nozzle is relatively close, so that the light can more easily illuminate the landing point of the water, allowing the user to observe the water spray path and cleaning process, thereby improving the ease of operation.
[0107] In some embodiments, the light-emitting portion 132 may include at least two, and the nozzle 114 is disposed between at least the light-emitting portions 132. This arrangement, where the nozzle 114 is surrounded by at least two light-emitting portions 132, allows light to be focused around the nozzle 114, illuminating the water flow and enabling the user to observe the water spray path and cleaning process, thus improving ease of operation.
[0108] Since the light-emitting part 132 is connected to the light-guiding part 134, the nozzle 114 is disposed between at least the light-guiding parts 134, that is, multiple light-guiding parts 134 are arranged around the nozzle 114. This allows the light to be focused around the nozzle 114, illuminating the water flow and enabling the user to observe the water spray path and cleaning process, thus improving ease of operation.
[0109] In some embodiments, the distance between the plurality of light guides 134 gradually decreases along the first direction X, so that the plurality of light guides 134 can be arranged in a direction closer to the nozzle 114, so that the light can more easily illuminate the landing point of the water, allowing the user to observe the water spray path and cleaning process, thereby improving the ease of operation.
[0110] In other embodiments, there may be multiple light guides 134. Along the first direction X, multiple guides 134 are inclined toward the direction of the nozzle 114. Specifically, there may be three, four, five, six, etc., and the specific number is not specifically limited.
[0111] In some embodiments, the light-emitting part 132 and the nozzle 114 are located on the front side of the housing 110. This allows light to be emitted from the front side of the housing 110 onto the surface to be cleaned, enabling the user to observe the situation in front of the cleaning equipment and facilitating cleaning.
[0112] In some embodiments, the steam or liquid ejected from the nozzle 114 and the light emitted from the light-emitting section 132 at least partially overlap on the surface to be cleaned. This allows the light to more easily illuminate the water's landing point, enabling the user to observe the water's landing point, spray path, and cleaning process, thus improving ease of operation.

The cleaning device 10 can be a floor scrubber, a sweeper, a vacuum cleaner, etc.
