[0048] In related technologies, cleaning equipment suffers from the technical problem of a small illuminated area. This disclosure provides a brush head, cleaning equipment, and cleaning system that can at least partially solve the technical problem of a small illuminated area in cleaning equipment.

[0049] This disclosure is described below with reference to the accompanying drawings and specific embodiments:

[0050] As shown in Figures 1 to 4, the brush head 100 includes a housing 120, a cleaning section 140, a light guide 160, and a light source 180. The housing 120 has a mounting cavity 120a, and the cleaning section 140 is mounted in the mounting cavity 120a. The cleaning section 140 is used to clean the surface 3 to be cleaned. The light source 180 is disposed opposite to the light guide 160, and the light guide 160 has a light-emitting surface 160a located outside the mounting cavity 120a. The light guide 160 is inclined away from the cleaning section 140 along the direction from the light source 180 to the light-emitting surface 160a.

[0051] The cleaning part 140 is installed inside the mounting cavity 120a, and at least a portion of the cleaning part 140 protrudes outside the housing 120. When the brush head 100 is running, the cleaning part 140 rotates at high speed. Since at least a portion of the cleaning part 140 extends outside the housing 120, the rotating cleaning part 140 can contact the surface 3 to be cleaned, wiping the surface 3 and thus cleaning it. An air outlet 120b is provided on the outer surface of the housing 120 for spraying steam. The steam sprayed from the air outlet 120b can reach the surface of the object to be cleaned, softening, dissolving, and removing stubborn dirt from the surface 3, thus improving the cleaning effect.

[0052] The light source 180 can emit light and can be a light strip, light-emitting panel, etc. The light source 180 and the light guide 160 are arranged opposite each other, so that the light emitted by the light source 180 can illuminate the light guide 160, and through the conduction of the light guide 160, it is diffused from the light-emitting surface 160a of the light guide 160, thereby illuminating the surface to be cleaned 3 and the steam ejected from the air outlet 120b. It should be noted that both the light guide 160 and the light source 180 are mounted on the housing 120.

[0053] In the direction from the light source 180 to the light-emitting surface 160a, the light guide 160 is inclined away from the cleaning section 140. That is, in the direction from the light source 180 to the light-emitting surface 160a, the height of the light guide 160 gradually increases. With this design, one end of the light-emitting surface 160a of the light guide 160 is higher than the end near the light source 180. The higher height of the light-emitting surface 160a helps to expand the illuminated area of ​​the light emitted from the light-emitting surface 160a, reduce the blind spots, and facilitate the user's observation of the surface 3 to be cleaned. It also facilitates the user's observation of the coverage and effect after the steam is sprayed out.

[0054] The brush head 100 has a forward direction X and a height direction Z, and the cleaning part 140 has an axis Y. The forward direction X, the height direction Z and the axis Y are perpendicular to each other.

[0055] In some embodiments, the light guide 160 includes a light guide portion 162 and a protective portion 164, which are connected. The light guide portion 162 has a light emitting surface 160a, and the light source 180 is disposed opposite to the light guide portion 162. The light guide portion 162 and / or the protective portion 164 are connected to the housing 120. Along the direction from the light source 180 to the light emitting surface 160a, the light guide portion 162 is inclined away from the cleaning portion 140.

[0056] The light guide 162 and the protective part 164 are fixedly connected. The light source 180 is disposed opposite to the light guide 162, so that the light emitted by the light source 180 can illuminate the light guide 162, and be dispersed from the light emitting surface 160a of the light guide 160 through the conduction of the light guide 160, thereby illuminating the steam ejected from the air outlet 120b and the surface 3 to be cleaned.

[0057] In some embodiments, along the forward direction of the brush head 100, the protective portion 164 is located in front of the cleaning portion 140; along the height direction of the brush head 100, the light guide portion 162 is located above the cleaning portion 140. The light guide portion 162's placement in the upper region of the cleaning portion 140 utilizes the space above the cleaning portion 140, contributing to a smaller overall size of the brush head 100. The protective portion 164, located in front of the cleaning portion 140, provides a degree of protection to the cleaning portion 140, preventing it from impacting obstacles such as table legs or chair legs, thus ensuring the cleaning effect of the cleaning portion 140.

[0058] In some embodiments, along the forward direction of the brush head 100, the light source 180 is disposed on the rear side of the light guide portion 162, utilizing the space on the rear side of the light guide portion 162, which helps to improve the compactness of the brush head 100.

[0059] In some embodiments, the air outlet 120b is located below the protective portion 164 along the height direction of the brush head 100. This design helps to bring the air outlet 120b close to the ground, allowing the high-temperature steam emitted from the air outlet 120b to better soften and dissolve the dirt on the surface 3 to be cleaned. Furthermore, positioning the air outlet 120b below the protective portion 164 can, to some extent, prevent the protective portion 164 from interfering with the emission of the high-temperature steam.

[0060] In some embodiments, the light guide portion 162 and the protective portion 164 are integrally formed, which facilitates the processing of the light guide component 160. The light guide portion 162 and the protective portion 164 can be integrally formed by injection molding or other methods.

[0061] In some embodiments, the light guide portion 162 and the protective portion 164 are arranged at an obtuse angle. The obtuse angle between the light guide portion 162 and the protective portion 164 helps to increase the area between the light guide portion 162 and the protective portion 164, making it easier for the cleaning portion 140 to be installed between the light guide portion 162 and the protective portion 164.

[0062] In some embodiments, the light guide portion 162 is provided with a first latching portion 1622, and the protective portion 164 is provided with a second latching portion 1642; both the first latching portion 1622 and the second latching portion 1642 are latched onto the housing 120. With this design, the light guide 160 is latched onto the housing 120 via the first latching portion 1622 and the second latching portion 1642. When the light guide portion 162 is worn or otherwise damaged, the light guide 160 can be removed and replaced, making it convenient for the user to use the brush head 100.

[0063] The first latching portion 1622 and the second latching portion 1642 can be either a latching connector or a latching slot, and this disclosure does not limit the types of latching components. When the first latching portion 1622 is a latching slot, a latching connector is provided at a corresponding position on the housing 120, and the latching connector is latched into the slot. Similarly, when the second latching portion 1642 is a latching slot, a latching connector is provided at a corresponding position on the housing 120, and the latching connector is latched into the slot.

[0064] As shown in Figures 5 to 7, in some embodiments, the light guide 160 further includes a reflective surface 160b, which is disposed on the side of the light guide 160 near the light emitting surface 160a, and is used to reflect the light within the light guide 160 onto the light emitting surface 160a. By providing the reflective surface 160b, more light is reflected onto the light emitting surface 160a, thereby ensuring the illumination intensity of the light emitted from the light emitting surface 160a. In some embodiments, the reflective surface 160b is arc-shaped.

[0065] As shown in Figures 4 to 8, in some embodiments, the housing 120 includes a water storage housing 122, a support housing 124, and a jet nozzle 126; the support housing 124 has a mounting cavity 120a, the water storage housing 122 has a liquid storage cavity 122a, and the jet nozzle 126 has a steam outlet 120b; both the water storage housing 122 and the jet nozzle 126 are connected to the support housing 124; the light guide 162 and the protective part 164 are respectively connected to the support housing 124 and the jet nozzle 126.

[0066] The water storage housing 122 has a liquid storage chamber 122a, which is used to store cleaning fluid or clean water. The liquid in the liquid storage chamber 122a can be discharged onto the cleaning part 140 or onto the surface 3 to be cleaned, so as to clean the surface 3. The support housing 124 can support the cleaning part 140 and components such as the motor that drives the cleaning part 140 to rotate. In some embodiments, the brush head 100 also includes rollers, and the support housing 124 can also support the rollers. In these embodiments, the light guide part 162 is connected to the support housing 124, and the protective part 164 is connected to the jet 126.

[0067] In some embodiments, the jet element 126 and the support housing 124 can be detachably connected. With this design, when the air outlet 120b is blocked and cannot be used, the jet element 126 can be removed and replaced with a new jet element 126 for user convenience.

[0068] In some embodiments, the water storage shell 122 and the support shell 124 are snapped together. With this design, when the liquid such as cleaning fluid or clean water in the water storage shell 122 is exhausted, the user can remove the water storage shell 122 for replenishment, which facilitates the replenishment of liquid.

[0069] In some embodiments, the light guide portion 162 is provided with a limiting portion 1624, and the water storage housing 122 has a limiting groove 122a, with the limiting portion 1624 located within the limiting groove 122a. The light guide portion 162 and the water storage housing 122 are limited and engaged by the limiting portion 1624 and the limiting groove 122a. With this design, when installing the water storage housing 122, the limiting portion 1624 and the limiting groove 122a can be engaged to quickly align the water storage housing 122 with the support housing 124, thereby improving the installation efficiency of the water storage housing 122.

[0070] In some embodiments, the second latching portion 1642 is disposed on the side of the protective portion 164 away from the light guide portion 162; along the forward direction of the brush head 100, the first latching portion 1622 and the limiting portion 1624 are respectively disposed on both sides of the brush head 100. This design results in a larger distance between the first latching portion 1622 and the limiting portion 1624, facilitating their processing; similarly, a larger distance between the limiting portion 1624 and the protective portion 164 facilitates their processing.

[0071] In some embodiments, the brush head 100 includes a plurality of light sources 180, which are spaced apart along the axial direction of the cleaning section 140. The arrangement of the plurality of light sources 180 helps to increase the light intensity emitted by the light-emitting surface 160a, making it easier for the user to clearly observe the surface to be cleaned 3, the coverage area and coverage effect after steam is sprayed.

[0072] As shown in Figure 9, in some embodiments, the light guide 160 has a focusing groove 162a on the side near the light source 180. The focusing groove 162a can converge and guide the light emitted by the light source 180, so that the light can propagate more concentratedly, reduce the mutual influence between light rays, and thus reduce the generation of stray light.

[0073] In some embodiments, a focusing groove 162a is provided on the side of the light guide 162 near the light source 180. This design helps to bring the focusing groove 162a closer to the light source 180, allowing the focusing groove 162a to better converge and guide the light emitted by the light source 180, enabling the light to propagate more concentratedly, reducing the mutual influence between light rays, and thus reducing the generation of stray light.

[0074] In some embodiments, multiple focusing slots 162a are provided, and the multiple focusing slots 162a are spaced apart along the axial direction of the cleaning section 140. This design helps to enhance the focusing effect of light, reduce the generation of stray light, increase the illumination intensity of the light emitted from the light-emitting surface 160a, and ensure the clarity of the illumination.

[0075] In some embodiments, a plurality of light sources 180, the same number as the focusing slots 162a, are provided. The plurality of light sources 180 are spaced apart along the axial direction of the cleaning section 140, and the plurality of focusing slots 162a are arranged in a one-to-one correspondence with the plurality of light sources 180. The light emitted by each light source 180 enters its corresponding focusing slot 162a, reducing the mutual influence between the light sources 180 and helping to reduce the generation of stray light.

[0076] In some embodiments, six light sources 180 are provided, which are spaced apart along the axial direction of the cleaning section 140. Six light-concentrating grooves 162a are provided, which correspond one-to-one with the six light sources 180.

[0077] In some embodiments, the focusing groove 162a is triangular. The triangular focusing groove 162a helps to reduce the generation of stray light.

[0078] In some embodiments, in order to reduce the generation of stray light, the focusing groove 162a is an isosceles triangle, and the base of the isosceles triangle focusing groove 162a is parallel to the axial direction of the cleaning section 140 and close to the light source 180.

[0079] In some embodiments, the focusing groove 162a has an opening 162b, which is disposed opposite to the light source 180. The opening 162b is disposed opposite to the light source 180, so that the light emitted by the light source 180 can enter the focusing groove 162a through the opening 162b, which helps to reduce the generation of stray light.

[0080] In some embodiments, the light guide portion 162 is provided with a blocking portion 1626, which is disposed at the opening 162b of the light-concentrating groove 162a and blocks the opening 162b. It should be noted that the blocking portion 1626 is transparent, allowing light to pass through it into the light-concentrating groove 162a. The blocking portion 1626 blocks the opening 162b to prevent debris or other contaminants from entering the light-concentrating groove 162a and affecting light propagation.

[0081] As shown in Figures 9 and 10, in some embodiments, the light guide 160 has a clearance groove 162c on the side near the light source 180, and the steam generating unit 190 of the brush head 100 is located within the clearance groove 162c. The clearance groove 162c is used to avoid the steam generating unit 190. The steam generating unit 190 is capable of generating steam and ejecting the steam through the air outlet 120b of the jet member 126 to soften or dissolve dirt. In embodiments where the light guide 160 includes a light guide portion 162, the light guide portion 162 has a clearance groove 162c on the side near the light source 180.

[0082] In some embodiments, along the axial direction of the cleaning section 140, a clearance groove 162c is provided in the central region of the cleaning section 140, and a plurality of focusing grooves 162a are provided, with the multiple focusing grooves 162a located on both sides of the clearance groove 162c. This design helps to distribute light evenly along the axial direction of the cleaning section 140.

[0083] In some embodiments, the brush head 100 further includes a motor, and the cleaning part 140 is installed at the output end of the motor. The motor drives the cleaning part 140 to rotate, thereby wiping the surface 3 to be cleaned.

[0084] In some embodiments, along the height direction of the brush head 100, the light-emitting surface 160a is higher than the air outlet 120b, so that the light emitted from the light-emitting surface 160a can illuminate the surface 3 to be cleaned and the steam ejected from the air outlet 120b. Of course, it is also feasible for the light-emitting surface 160a to be lower than the air outlet 120b. The steam ejected from the air outlet 120b will fall under the action of gravity, and after falling a certain distance, it can be irradiated by the light emitted from the light-emitting surface 160a.

[0085] As shown in Figure 4, in some embodiments, the angle α between the light-emitting surface 160a and the height direction of the brush head 100 is a right angle or an acute angle. With this design, the light-emitting surface 160a is tilted towards the surface 3 to be cleaned, which helps to concentrate more of the light emitted by the light-emitting surface 160a on the surface 3 to be cleaned, making it easier for the user to observe the surface 3 to be cleaned and to observe the coverage and effect after the steam is sprayed out.

[0086] In some embodiments, the included angle α is between 45° and 90°. The included angle α can be 45°, 50°, 60°, 90°, etc. When the included angle α is within the range of 45° to 90°, it can effectively expand the illumination range, ensure light intensity, and reduce blind spots. If the included angle α is less than 45°, the light will propagate more in the forward direction of the brush head 100. Although the illuminated area is larger, there are more blind spots, and the light intensity at the surface to be cleaned 3 and the air outlet 120b is lower, making it difficult for the user to clearly observe the surface to be cleaned 3, the coverage area after steam is emitted, and the coverage effect. If the included angle α is greater than 90°, the light will propagate more downward in the height direction of the brush head 100. Not only is the illuminated area smaller, but there are also more blind spots, and less light reaches the surface to be cleaned 3. Similarly, it is difficult for the user to clearly observe the surface to be cleaned 3, the coverage area after steam is emitted, and the coverage effect. Therefore, setting the included angle α within the range of 45° to 90° can effectively expand the illumination range, ensure the illumination intensity, and reduce the blind spots, thus providing users with a better observation experience.

[0087] In some embodiments, the angle α between the light-emitting surface 160a and the height direction of the brush head 100 is 0° to 60°. The value of the angle α can be 0°, 45°, 50°, 60°, etc. When the angle α is within the range of 0° to 60°, the illumination range can be expanded, the light intensity can be guaranteed, and the blind spots in the light can be reduced. If the angle α is less than 0°, the light will propagate upwards and cannot illuminate the surface to be cleaned 3, so the user cannot observe the surface to be cleaned 3, the coverage area after the steam is sprayed, and the coverage effect. If the angle α is greater than 60°, the light will propagate downwards more in the height direction of the brush head 100, the illuminated area will be smaller, and there will be more blind spots in the light, so less light reaches the surface to be cleaned 3, making it difficult for the user to clearly observe the surface to be cleaned 3, the coverage area after the steam is sprayed, and the coverage effect. Therefore, setting the angle α within the range of 0° to 60° can expand the illumination range, guarantee the light intensity, and reduce the blind spots in the light, providing the user with a better observation experience.

[0088] As shown in Figure 11, in some embodiments, light emitted from the light-emitting surface 160a forms an illuminated area on the surface 3 to be cleaned; along the height direction of the brush head 100, the housing 120 forms a projection of the main body 200 on the surface 3 to be cleaned; along the forward direction of the brush head 100, the distance L1 between the illuminated area and the projection of the main body 200 is less than 10 mm. Setting the distance L1 between the illuminated area and the projection of the main body 200 to less than 10 mm can reduce the blind spot area in front of the brush head 100, which helps to provide users with a better observation experience.

[0089] Along the forward direction of the brush head 100, the foremost position of the housing 120 is the highest point of the light dead angle. Along the forward direction of the brush head 100, the area in front of the line connecting the highest point of the light-emitting surface 160a and the highest point of the light dead angle (i.e., the dotted line in Figure 11) is the area that can be covered by light, i.e., the illuminated area, while the area behind it is the area that cannot be covered by light, i.e., the light dead angle area.

[0090] In some embodiments, along the height direction of the brush head 100, the projection of the light-emitting surface 160a onto the surface 3 to be cleaned is located within the projection of the housing 120 onto the surface 3 to be cleaned. That is, the light-emitting surface 160a is positioned above the housing 120, and horizontally, the light-emitting surface 160a does not extend beyond the housing 120. With this design, the light-emitting surface 160a is less likely to collide with table legs, chair legs, walls, etc., during brush head 100 operation, reducing wear on the light-emitting surface 160a, allowing light to be emitted evenly from the light-emitting surface 160a, ensuring light intensity, and extending the service life of the light-emitting surface 160a. Furthermore, this design also helps to reduce the horizontal space occupied by the brush head 100, improving the compactness of the brush head 100.

[0091] In some implementations, the distance L2 between the foremost point of the light-emitting surface 160a and the foremost point of the housing 120 along the forward direction of the brush head 100 is 5mm to 20mm. It is easy to understand that, with other dimensional parameters constant, the larger the distance L2, the larger the blind spot area; conversely, the smaller the distance L2, the smaller the blind spot area. When the distance L2 is greater than 20mm, most of the light emitted from the light-emitting surface 160a is blocked by the housing 120, resulting in a larger blind spot area and a smaller light coverage area, making it difficult for the user to observe the surface to be cleaned and the coverage area and effect after steam is emitted. While when the distance is less than 5mm, although the blind spot area is smaller and the illuminated area is larger, the light-emitting surface 160a is prone to collisions with obstacles such as table legs and chair legs during use, causing scratches on the light-emitting surface 160a and affecting the uniformity and brightness of the illumination. Setting the distance L2 between the foremost point of the light-emitting surface 160a and the foremost point of the housing 120 to 5mm to 20mm ensures a larger illuminated area and reduces the blind spot area, while also preventing the light-emitting surface 160a from being scratched to a certain extent, thus ensuring the stability and durability of the lighting effect.

[0092] In some embodiments, the housing 120 has a steam outlet 120b. Along the forward direction of the brush head 100, the distance L2 between the foremost point of the light-emitting surface 160a and the foremost point of the housing 120 is 5mm to 20mm. Along the forward direction of the brush head 100, the foremost point of the housing 120 is the highest point of the blind spot; that is, along the forward direction of the brush head 100, the distance H1 between the highest point of the blind spot and the highest point of the steam outlet 120b is 5mm to 20mm. This design reduces the height difference between the highest point of the blind spot and the steam outlet 120b, and the steam outlet 120b is closer to the highest point of the blind spot. After the steam is ejected from the steam outlet 120b, it travels in the air for a longer time, which helps the steam travel a greater distance in the forward direction of the brush head 100. This allows the user to more clearly observe the coverage and effect of the steam after it is ejected, facilitating control of the steam cleaning area, monitoring the presence of steam, and preventing steam burns.

[0093] In some embodiments, along the height direction of the brush head 100, the distance H2 between the highest point of the light-emitting surface 160a and the surface 3 to be cleaned is 55mm to 70mm. With a fixed position of the highest point of the light-dead angle, a larger distance H2 results in a smaller light-dead angle area and a larger illumination range, but the intensity of the light reaching the surface 3 to be cleaned is weaker because the light gradually diffuses and attenuates during propagation. Conversely, with a fixed position of the highest point of the light-dead angle, a smaller distance H2 results in a larger light-dead angle area and a smaller illumination range, but the intensity of the light reaching the surface 3 to be cleaned is stronger. Setting the distance H2 between the highest point of the light-emitting surface 160a and the surface 3 to be cleaned to 55mm to 70mm achieves a balance between illumination range and intensity. This distance range ensures that the light reaches the surface 3 to be cleaned with sufficient intensity, avoiding light loss and reduced brightness due to excessive distance, while also ensuring that the light emitted from the light-emitting surface 160a covers a sufficiently large area and reduces the light-dead angle area, thus meeting the illumination requirements of the brush head 100.

[0094] As shown in Figure 12, based on the same inventive concept, this disclosure also provides a cleaning device 10, including a main body 200 and the aforementioned brush head 100, with the brush head 100 mounted on the main body 200. The housing 120 of the main body 200 and the brush head 100 is connected, allowing a user to hold the main body 200 and control the direction of the brush head 100. Since the cleaning device 10 includes the aforementioned brush head 100, it naturally possesses all the beneficial effects of the brush head 100, which will not be elaborated upon here.

[0095] In some embodiments, the main body 200 is mounted on the support housing 124 to facilitate the removal of the water storage housing 122 from the support housing 124.

[0096] In some embodiments, the main body 200 includes a support rod 220 and a grip handle 240 disposed on the support rod 220, with buttons and the like provided on the grip handle 240. Users can grip the grip handle 240 of the main body 200 to control the direction of the cleaning device 10. Users can also turn the cleaning device 10 on or off, or change the cleaning mode, by pressing the buttons, making it convenient for users to operate.

[0097] In some embodiments, the main body 200 also includes a wastewater tank 260, which is detachably connected to the support rod 220. Dirty water generated during the cleaning process can be stored in the wastewater tank 260. The design of the wastewater tank 260 facilitates wastewater collection; its detachable connection to the support rod 220 allows users to easily empty the wastewater from the tank and clean it.

[0098] In some embodiments, the cleaning device 10 is a household floor scrubber, and the cleaning section 140 is the roller brush of the household floor scrubber.

[0099] As shown in Figure 13, based on the same inventive concept, this disclosure also provides a cleaning system 1, including a cleaning base station 20 and the aforementioned cleaning device 10. The cleaning base station 20 can support the cleaning device 10 and prevent the cleaning device 10 from tipping over.

[0100] In some embodiments, the cleaning base station 20 can power the cleaning device 10 so that the cleaning device 10 can be charged.

[0101] In some embodiments, the cleaning base station 20 includes a blower unit that can blow out cold or hot air to quickly dry the cleaning section 140 of the cleaning device 10.

[0102] In the direction from the light source to the light-emitting surface, the light guide is tilted away from the cleaning area. In other words, the height of the light guide gradually increases from the light source to the light-emitting surface. This design results in one end of the light-emitting surface being higher than the end closest to the light source, thus expanding the illuminated area of ​​the light emitted from the light-emitting surface, reducing blind spots, and facilitating user observation of the coverage and effect of the steam spray. It also makes it easier for users to observe the surface to be cleaned.
