[0028] In addition, it is required to understand the present application not only through the actual terms used, but also through the meanings implied by each term.
[0029] The following will describe in detail the technical solutions provided by each embodiment of the present application in conjunction with the drawings.
[0030] An embodiment of the present application provides a floor washer. Refer to Figures 1 to 4 , the floor washer 100 provided by the embodiment of the present application includes: a mounting frame 110, a roller floor brush 120, a light guide cover 130, and a light emitting element 140.
[0031] The drum floor brush 120 is rotatably connected to the mounting bracket 110. It should be noted that regarding the specific way of the rotational connection between the drum floor brush 120 and the mounting bracket 110, and how the rotary drive of the floor washer 100 drives the drum floor brush 120 to rotate, reference can be made to the prior art. Therefore, no further elaboration will be made here.
[0032] Further, the light guide cover 130 is connected to the mounting bracket 110, and the light guide cover 130 is located above the drum floor brush 120. It should be noted that in the related art, there is also a drum cover for the floor washer. The solution provided in the embodiments of the present application is equivalent to replacing the drum cover in the related art with the light guide cover 130 having light transmissivity. It should also be noted that as for the light transmittance parameter of the light guide cover 130, those skilled in the art can flexibly select according to actual needs, and will not be listed here. Of course, in other embodiments, the light guide cover 130 can also be separately provided on the basis of the floor washer in the related art. Exemplarily, the light guide cover 130 can be attached below the drum cover in the related art.
[0033] Further, the light guide cover 130 is provided with a light incident side 131 and a light exit side 132. The light exit side 132 is exposed on the outer surface of the floor washer 100, and the light exit side 132 is inclined downward. The light emitting element 140 faces the light incident side 131, and the light emitted by the light emitting element 140 can enter the light guide cover 130 through the light incident side 131 and exit from the light exit side 132.
[0034] In this way, in the embodiments of the present application, since the light emitted by the light emitting element 140 can enter the light guide cover 130 through the light incident side 131 of the light guide cover 130 and exit from the light exit side 132 of the light guide cover 130 to illuminate the area around the floor washer 100, it is convenient for the cleaning personnel to observe the stains on the ground. Furthermore, when the cleaning personnel observe the stains, the cleaning effect on the ground can be improved by increasing the cleaning intensity of the stained area.
[0035] In some embodiments, the light guide cover 130 is disposed opposite to the drum floor brush 120, and the light guide cover 130 is exposed on the outer surface of the floor washer 100. In this way, the cleaning personnel can observe the drum floor brush 120 through the light guide cover 130 to judge the cleaning degree of the drum floor brush 120, and thus it is convenient for the cleaning personnel to regularly clean the drum floor brush 120.
[0036] Reference Figure 1 and Figure 3, in some embodiments, the light incident side 131 faces away from the light emitting side 132, and the light emitting side 132 is disposed on a side of the light guide cover 130 in front of the rotation axis of the drum floor brush 120. The angle between the light emitting side 132 and the horizontal plane is 10 to 80 degrees. In this way, the light emitted by the light emitting element 140 can better illuminate the ground in front of the floor washer 100, so that the cleaning personnel can easily observe the stains on the ground in front of the floor washer 100, and thus focus on cleaning the stained area.
[0037] It should be noted that the "front" in "in front of the rotation axis of the drum floor brush 120" may mean that when the cleaning personnel hold the handle of the floor washer in a normal posture, the direction that the cleaning personnel's eyes look at is the front. Of course, those skilled in the art can also understand the "front" based on common general knowledge.
[0038] In some embodiments, the light guide cover 130 includes a cover portion 133 and a connecting portion 134 connected to each other, and the connecting portion 134 is connected to the mounting bracket 110. The cover portion 133 covers above the drum floor brush 120, the light incident side 131 is located on a side of the connecting portion 134 away from the cover portion 133, and the light emitting side 132 is located on a side of the cover portion 133 away from the connecting portion 134.
[0039] Exemplarily, the side of the cover portion 133 facing the drum floor brush 120 is an arc surface. The axis of the arc surface is collinear with the axis of the drum floor brush 120. In other words, the projection of the side of the cover portion 133 facing the drum floor brush 120 along the axis of the drum floor brush 120 is an arc, and the center of the arc is located on the axis of the drum floor brush 120.
[0040] Exemplarily, the connecting portion 134 includes a substrate and a protruding portion provided on the substrate. The light emitted by the light emitting element 140 is mainly reflected in the substrate and then directed to the cover portion 133. The protruding portion can function to connect with the mounting bracket 110.
[0041] In some embodiments, the light guide cover 130 further includes a transition portion 135. The transition portion 135 is located between the cover portion 133 and the connecting portion 134, and the transition portion 135 is respectively connected to the cover portion 133 and the connecting portion 134. Exemplarily, the cover portion 133, the transition portion 135 and the connecting portion 134 are integrally formed to form the light guide cover 130. In this way, the manufacturing cost of the light guide cover 130 can be reduced by setting the light guide cover 130 as an integral structure.
[0042] Furthermore, a reflecting surface 1351 is provided at a portion of the transition part 135 opposite to the drum floor brush 120. The reflecting surface 1351 is configured to reflect the light emitted from the connecting part 134 to the cover part 133. In this way, by providing the reflecting surface 1351 between the cover part 133 and the connecting part 134, more light from the connecting part 134 can be directed towards the cover part 133, thereby enhancing the intensity of the light emitted from the light-emitting side 132.
[0043] Reference Figure 1 , in some embodiments, the reflecting surface 1351 is recessed in a direction away from the drum floor brush 120. In this way, the light emitted from the connecting part 134 can be better totally reflected at the reflecting surface 1351 and then reflected to the cover part 133, and then emitted from the light-emitting side 132.
[0044] It should be noted that, in some embodiments, the light entering the light guide cover 130 through the light-incident side 131 can be totally reflected between the upper and lower surfaces of the light guide cover 130 and then directed towards the light-emitting side 132 and finally emitted from the light-emitting side 132. Of course, in other embodiments, a reflective coating can also be provided on the upper and lower surfaces of the light guide cover 130 so that the upper and lower surfaces have a reflective function. It should also be noted that when a reflective coating is provided on the upper and lower surfaces of the light guide cover 130, it is not convenient for the cleaning staff to observe the cleaning state of the drum floor brush 120 through the light guide cover 130. Therefore, in a preferred embodiment, a reflective coating may not be provided on the upper and lower surfaces of the light guide cover 130, and based on the principle of total reflection, the light can be directed from the light-incident side 131 to the light-emitting side 132 and finally emitted from the light-emitting side 132.
[0045] Reference Figure 3 , in some embodiments, a first light condensing part 1311 is provided at a portion of the light-incident side 131 facing the light-emitting element 140. In this way, the first light condensing part 1311 can be used to better guide the light emitted by the light-emitting element 140 into the light guide cover 130.
[0046] Reference Figure 1 and Figure 4 , in some embodiments, the floor washer 100 further includes a light condensing member 150. The light condensing member 150 is provided with a second light condensing part 151, and the second light condensing part 151 is disposed between the light-incident side 131 and the light-emitting element 140. Exemplarily, the second light condensing part 151 is a condensing lens. In this way, the second light condensing part 151 can be used to better guide the light emitted by the light-emitting element 140 into the light guide cover 130.
[0047] In some embodiments, the number of the light-emitting elements 140 is plural, and the plural light-emitting elements 140 are arranged at intervals along a direction parallel to the rotation axis of the drum floor brush 120. Further, the number of the second light condensing portions 151 is equal to the number of the light-emitting elements 140, and the light-emitting elements 140 are respectively opposite to the second light condensing portions 151. Exemplarily, the light-emitting element 140 may be a light bulb or an LED (Light-emitting diode) lamp bead.
[0048] In some embodiments, the geometric centers of the light-emitting element 140, the second light condensing portion 151, and the first light condensing portion 1311 are linearly distributed.
[0049] In some embodiments, a microstructure array is provided on the light-emitting side 132. Exemplarily, the microstructure array includes a plurality of serrated microstructures. For example, the included angle between adjacent two sides of the serrated microstructure is 90 to 120 degrees. For example, the included angle between adjacent two sides of the serrated microstructure may specifically be 110 degrees. In this way, the light emitted from the light-emitting side 132 can be made more uniform; and the serrated microstructure can deflect the light, which can increase the area of the region illuminated by the light emitted from the light-emitting side 132.
[0050] In some embodiments, the distance between the bottom of the light-emitting side 132 and the bottom of the drum floor brush 120 in the vertical direction is 30 to 60 millimeters.
[0051] It should be noted that in this document, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variation thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.
[0052] Although the embodiments of the present application have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirits of the embodiments of the present application, and the scope of the embodiments of the present application is defined by the appended claims and their equivalents.
