[0046] In the related art, the cleaning device has the technical problem of small illumination area.This application provides a brush head, a cleaning device and a cleaning system, which can at least solve the technical problem of small illumination area of the cleaning device to a certain extent.

[0047] The application will be described below in conjunction with the drawings and specific embodiments:

[0048] As shown in Figures 1 to 4 The brush head 100 includes a housing 120, a cleaning part 140, a light guide member 160 and a light source 180.The housing 120 has a mounting cavity 120a, and the cleaning part 140 is mounted in the mounting cavity 120a, and the cleaning part 140 is used for cleaning the surface to be cleaned 3.The light source 180 is arranged opposite to the light guide member 160, and the light guide member 160 has a light emitting surface 160a, and the light emitting surface 160a is located outside the mounting cavity 120a.Along the direction from the light source 180 to the light emitting surface 160a, the light guide member 160 is inclinedly arranged away from the cleaning part 140.

[0049] The cleaning part 140 is mounted in the mounting cavity 120a, and at least part of the cleaning part 140 protrudes out of the shell 120. When the brush head 100 is running, the cleaning part 140 rotates at a high speed, and at least part of the cleaning part 140 protrudes out of the shell 120, so that the rotating cleaning part 140 can contact the surface 3 to be cleaned and wipe the surface 3 to be cleaned, thereby cleaning the surface 3 to be cleaned. The outer surface of the shell 120 is provided with an air outlet 120b for spraying steam, and the steam sprayed by the air outlet 120b can reach the surface of the object to be cleaned, so that the stubborn dirt on the surface 3 to be cleaned is softened, dissolved and stripped by impact, thereby improving the cleaning effect.

[0050] The light emitting source 180 can emit light, which can be a light strip, a light emitting plate or the like. The light emitting source 180 is arranged opposite to the light guide 160, so that the light emitted by the light emitting source 180 can be irradiated on the light guide 160 and be emitted from the light emitting surface 160a of the light guide 160 through the conduction of the light guide 160, thereby illuminating the surface 3 to be cleaned and the steam sprayed from the air outlet 120b. It should be noted that the light guide 160 and the light emitting source 180 are both mounted on the shell 120.

[0051] In the direction from the light emitting source 180 to the light emitting surface 160a, the light guide 160 is arranged to be inclined away from the cleaning part 140, that is, in the direction from the light emitting source 180 to the light emitting surface 160a, the height of the light guide 160 gradually increases. After such design, one end of the light emitting surface 160a of the light guide 160 is higher than the end close to the light emitting source 180, and the height of the light emitting surface 160a is relatively high, which helps to expand the illumination area of the light emitted from the light emitting surface 160a, reduces the dead angle area of the light, facilitates the user to observe the surface 3 to be cleaned, and also facilitates the user to observe the coverage range and effect of the steam after being sprayed.

[0052] The brush head 100 has a forward direction X and a height direction Z, and the cleaning part 140 has an axial direction Y, and the forward direction X, the height direction Z and the axial direction Y are perpendicular to each other.

[0053] In some embodiments, the light guide 160 includes a light guide part 162 and a protection part 164, the light guide part 162 and the protection part 164 are connected, the light guide part 162 has a light emitting surface 160a, and the light emitting source 180 is arranged opposite to the light guide part 162; the light guide part 162 and / or the protection part 164 are connected to the shell 120; in the direction from the light emitting source 180 to the light emitting surface 160a, the light guide part 162 is arranged to be inclined away from the cleaning part 140.

[0054] The light guide part 162 and the protection part 164 are fixedly connected. The light emitting source 180 is arranged opposite to the light guide part 162, so that the light emitted by the light emitting source 180 can be irradiated on the light guide part 162 and be diffused out from the light emitting surface 160a of the light guide part 160 through the conduction of the light guide part 160, and then illuminate the vapor sprayed from the air outlet 120b and the surface 3 to be cleaned.

[0055] In some embodiments, along the advancing direction of the brush head 100, the protection part 164 is located at the front side of the cleaning part 140; along the height direction of the brush head 100, the light guide part 162 is located at the upper side of the cleaning part 140. The light guide part 162 is arranged at the upper side region of the cleaning part 140, which utilizes the space at the upper side of the cleaning part 140, and helps to make the size of the brush head 100 smaller. The protection part 164 is located at the front side of the cleaning part 140, which can protect the cleaning part 140 to a certain extent, avoid the cleaning part 140 from colliding with obstacles such as table legs and chair legs, and ensure the cleaning effect of the cleaning part 140.

[0056] In some embodiments, along the advancing direction of the brush head 100, the light emitting source 180 is arranged at the rear side of the light guide part 162, which utilizes the space at the rear side of the light guide part 162, and helps to improve the compactness of the brush head 100.

[0057] In some embodiments, along the height direction of the brush head 100, the air outlet 120b is arranged at the lower side of the protection part 164. Such design helps to make the air outlet 120b close to the ground, so that the high-temperature vapor sprayed from the air outlet 120b can better soften and dissolve the dirt on the surface 3 to be cleaned. Moreover, arranging the air outlet 120b at the lower side of the protection part 164 can avoid the interference of the protection part 164 to the spraying of the high-temperature vapor to a certain extent.

[0058] In some embodiments, the light guide part 162 and the protection part 164 are integrally formed, which facilitates the processing of the light guide part 160. The light guide part 162 and the protection part 164 can be integrally formed by injection molding or the like.

[0059] In some embodiments, the light guide part 162 and the protection part 164 are arranged at an obtuse angle. Arranging the light guide part 162 and the protection part 164 at an obtuse angle helps to make the region between the light guide part 162 and the protection part 164 larger, which facilitates the installation of the cleaning part 140 between the light guide part 162 and the protection part 164.

[0060] In some embodiments, the light guide part 162 is provided with a first clamping part 1622, and the protection part 164 is provided with a second clamping part 1642; the first clamping part 1622 and the second clamping part 1642 are clamped with the shell 120. In this way, the light guide part 160 is clamped on the shell 120 through the first clamping part 1622 and the second clamping part 1642, and when the light guide part 162 is worn or needs to be damaged, the light guide part 160 can be removed and replaced, which is convenient for the user to use the brush head 100.

[0061] The first clamping part 1622 and the second clamping part 1642 can be a clamping head or a clamping groove, which is not limited in the present application. When the first clamping part 1622 is a clamping groove, a clamping head is arranged at the corresponding position of the shell 120 and clamped in the clamping groove. When the first clamping part 1622 is a clamping head, a clamping groove is arranged at the corresponding position of the shell 120 and the clamping head is clamped in the clamping groove. Similarly, when the second clamping part 1642 is a clamping groove, a clamping head is arranged at the corresponding position of the shell 120 and clamped in the clamping groove. When the second clamping part 1642 is a clamping head, a clamping groove is arranged at the corresponding position of the shell 120 and the clamping head is clamped in the clamping groove.

[0062] As shown in Figures 5 to 7 some embodiments, the light guide part 160 also has a reflecting surface 160b arranged on the side of the light guide part 160 close to the light emitting surface 160a, for reflecting the light in the light guide part 160 to the light emitting surface 160a. Through the arrangement of the reflecting surface 160b, more light is reflected to the light emitting surface 160a to ensure the light intensity of the light emitted by the light emitting surface 160a. In some embodiments, the reflecting surface 160b is in the shape of a circular arc.

[0063] As shown in Figures 4 to 8 some embodiments, the shell 120 includes a water storage shell 122, a support shell 124 and a jet part 126; the support shell 124 has a mounting cavity 120a, the water storage shell 122 has a liquid storage cavity 122a, and the jet part 126 has a gas outlet 120b for discharging steam; the water storage shell 122 and the jet part 126 are connected with the support shell 124; the light guide part 162 and the protection part 164 are connected to the support shell 124 and the jet part 126 respectively.

[0064] The water storage shell 122 has a liquid storage cavity 122a for storing cleaning liquid or clean water, etc. The liquid in the liquid storage cavity 122a can be discharged onto the cleaning part 140 or onto the surface 3 to be cleaned, so as to clean the surface 3 to be cleaned. The support shell 124 can support the cleaning part 140 and a motor or the like for driving the cleaning part 140 to rotate. In some embodiments, the brush head 100 further comprises a roller, and the support shell 124 can further support the roller. In these embodiments, the light guide part 162 is connected with the support shell 124, and the protection part 164 is connected with the air jet 126.

[0065] In some embodiments, the air jet 126 is detachably connected with the support shell 124. In this design, when the air outlet 120b is blocked and cannot be used, the air jet 126 can be detached and replaced with a new air jet 126, so as to facilitate the user to use.

[0066] In some embodiments, the water storage shell 122 and the support shell 124 are clamped. In this design, when the cleaning liquid or clean water or the like in the water storage shell 122 is exhausted, the user can remove the water storage shell 122 for replenishment, thereby facilitating the replenishment of the liquid.

[0067] In some embodiments, the light guide part 162 is provided with a limiting part 1624, and the water storage shell 122 is provided with a limiting groove 122a, and the limiting part 1624 is located in the limiting groove 122a. The light guide part 162 and the water storage shell 122 are limitedly matched through the limiting part 1624 and the limiting groove 122a. In this design, when the water storage shell 122 is installed, the water storage shell 122 and the support shell 124 can be quickly aligned through the matching of the limiting part 1624 and the limiting groove 122a, thereby improving the installation efficiency of the water storage shell 122.

[0068] In some embodiments, the second clamping part 1642 is arranged on the side of the protection part 164 away from the light guide part 162; and the first clamping part 1622 and the limiting part 1624 are respectively arranged on two sides of the brush head 100 along the forward direction of the brush head 100. In this design, the distance between the first clamping part 1622 and the limiting part 1624 is large, which facilitates the machining of the first clamping part 1622 and the limiting part 1624; and the distance between the limiting part 1624 and the protection part 164 is large, which facilitates the machining of the limiting part 1624 and the protection part 164.

[0069] In some embodiments, the brush head 100 comprises a plurality of light emitting sources 180, and the plurality of light emitting sources 180 are arranged at intervals along the axis direction of the cleaning part 140. The arrangement of the plurality of light emitting sources 180 helps to improve the illumination intensity of the light emitted by the light emitting surface 160a, and facilitates the user to clearly observe the surface 3 to be cleaned, the coverage range and the coverage effect after the steam is sprayed.

[0070] As Figure 9As shown, in some embodiments, the light guide 160 is provided with a light collecting groove 162a on the side close to the light source 180. The light collecting groove 162a can converge and guide the light emitted by the light source 180, so that the light can be more concentrated, reducing the mutual influence between the light and the light, thereby reducing the generation of stray light.

[0071] In some embodiments, the light guide 162 is provided with a light collecting groove 162a on the side close to the light source 180. This design helps the light collecting groove 162a to be close to the light source 180, so that the light collecting groove 162a can better converge and guide the light emitted by the light source 180, so that the light can be more concentrated, reducing the mutual influence between the light and the light, thereby reducing the generation of stray light.

[0072] In some embodiments, the light collecting groove 162a is provided with a plurality of light collecting grooves 162a, and the plurality of light collecting grooves 162a are arranged along the axial direction of the cleaning part 140. Such design helps to enhance the focusing effect of the light, reduces the generation of stray light, improves the illumination intensity of the light emitted by the light emitting surface 160a, and ensures the clarity of the illumination.

[0073] In some embodiments, a plurality of light sources 180 corresponding to the number of light collecting grooves 162a are provided, and the plurality of light sources 180 are arranged along the axial direction of the cleaning part 140. Each light source 180 emits light into the corresponding light collecting groove 162a, reducing the mutual influence between the light sources 180 and the light sources 180, which helps to reduce the generation of stray light.

[0074] In some embodiments, six light sources 180 are provided, and the six light sources 180 are arranged along the axial direction of the cleaning part 140. Six light collecting grooves 162a are provided, and the six light collecting grooves 162a are arranged one-to-one corresponding to the six light sources 180.

[0075] In some embodiments, the light collecting groove 162a is a triangle. The triangular light collecting groove 162a helps to reduce the generation of stray light.

[0076] In some embodiments, in order to reduce the generation of stray light, the light collecting groove 162a is an isosceles triangle, and the base of the isosceles triangle light collecting groove 162a is parallel to the axial direction of the cleaning part 140 and close to the light source 180.

[0077] In some embodiments, the light collecting groove 162a has an opening 162b opposite the light source 180. The opening 162b is opposite the light source 180, so that the light emitted by the light source 180 can enter the light collecting groove 162a through the opening 162b, which helps to reduce the generation of stray light.

[0078] 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.

[0079] like Figure 9 and Figure 10 As shown, 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.

[0080] 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.

[0081] 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.

[0082] 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.

[0083] like Figure 4 As shown, 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.

[0084] 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.

[0085] 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.

[0086] like Figure 11 As shown, 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.

[0087] The most forward position of the shell 120 along the advancing direction of the brush head 100 is the highest point of the light dead angle. The front side area of the line (i.e., the dashed line in FIG. 16) connecting the highest point of the light dead angle and the highest point of the light-emitting surface 160a along the advancing direction of the brush head 100 is the area covered by the light, i.e., the illumination area, and the rear side area is the area not covered by the light, i.e., the light dead angle area. Figure 11

[0088] In some embodiments, the projection of the light-emitting surface 160a on the surface to be cleaned 3 is located within the projection of the shell 120 on the surface to be cleaned 3 along the height direction of the brush head 100. That is, the light-emitting surface 160a is arranged above the shell 120, and the light-emitting surface 160a does not protrude out of the shell 120 along the horizontal direction. In this way, the light-emitting surface 160a is less likely to collide with obstacles such as table legs, chair legs, and walls when the brush head 100 is in operation, reducing the wear of the light-emitting surface 160a, allowing the light to be evenly emitted from the light-emitting surface 160a, ensuring the illumination intensity, and prolonging the service life of the light-emitting surface 160a. In addition, this design also helps to reduce the space occupation of the brush head 100 in the horizontal direction, improving the compactness of the brush head 100.

[0089] In some embodiments, the distance L2 between the most forward end of the light-emitting surface 160a and the most forward end of the shell 120 along the advancing direction of the brush head 100 is 5 mm to 20 mm. It is easy to understand that, under the condition that other size parameters are constant, the larger the distance L2, the larger the light dead angle area, and the smaller the distance L2, the smaller the light dead angle area. When the distance L2 is greater than 20 mm, the light emitted by the light-emitting surface 160a is mostly blocked by the shell 120, resulting in a larger light dead angle area and a smaller coverage range of the light, which is not convenient for the user to observe the surface to be cleaned 3 and the coverage range and coverage effect after the steam is sprayed. When the distance is less than 5 mm, although the light dead angle area is small and the illumination area is large, the light-emitting surface 160a is prone to collision with obstacles such as table legs and chair legs during use of the brush head 100, resulting in scratches on the light-emitting surface 160a and affecting the uniformity and brightness of the illumination. By setting the distance L2 between the most forward end of the light-emitting surface 160a and the most forward end of the shell 120 to 5 mm to 20 mm, the illumination area can be ensured to be large and the light dead angle area can be reduced, and the light-emitting surface 160a can be prevented from being scratched to some extent, ensuring the stability and durability of the illumination effect.

[0090] ​In some embodiments, the shell 120 has an air outlet 120b for discharging steam, and the distance L2 between the front end of the light emitting surface 160a and the front end of the shell 120 in the advancing direction of the brush head 100 is 5-20 mm. In the advancing direction of the brush head 100, the front end of the shell 120 is the highest point of the light dead angle; that is, the distance H1 between the highest point of the light dead angle and the highest point of the air outlet 120b in the advancing direction of the brush head 100 is 5-20 mm. After such design, the height distance between the highest point of the light dead angle and the air outlet 120b is reduced, the air outlet 120b is close to the highest point of the light dead angle, and the steam discharged from the air outlet 120b has a longer movement time in the air, which helps the steam to move a farther distance in the advancing direction of the brush head 100, so that the user can more clearly observe the coverage range and effect of the steam after being discharged, and conveniently control the steam cleaning area, monitor whether the steam appears, and prevent being scalded by the steam.

[0091] In some embodiments, the distance H2 between the highest point of the light emitting surface 160a and the surface to be cleaned 3 in the height direction of the brush head 100 is 55-70 mm. In the case of a certain position of the highest point of the light dead angle, the greater the distance H2, the smaller the light dead angle area, the larger the light range, but the intensity of the light reaching the surface to be cleaned 3 is weaker, because the light gradually spreads and attenuates in the process of propagation. In the case of a certain position of the highest point of the light dead angle, the smaller the distance H2, the larger the light dead angle area, the smaller the light range, but the intensity of the light reaching the surface to be cleaned 3 is stronger. By setting the distance H2 between the highest point of the light emitting surface 160a and the surface to be cleaned 3 to 55-70 mm, a balance between the light range and the light intensity can be achieved. This distance range not only ensures that the light can reach the surface to be cleaned 3 with sufficient intensity, avoiding light loss and brightness reduction caused by too long distance, but also ensures that the light emitted by the light emitting surface 160a can cover a large enough area and the light dead angle area is reduced, meeting the lighting needs of the brush head 100.
