DETAILED DESCRIPTION
[0029] In order to make the purpose, technical scheme and advantages of the utility model more clear, the utility model will be described in detail below with the help of the drawings and specific embodiments.
[0030] Please refer to Figure 1 and Figure 2 It is disclosed that the utility model discloses a kind of scrubber 100, for washing ground.The scrubber 100 includes roller brush 1, machine shell 2, cover plate 31 and lighting assembly 3.The lighting assembly 3 and the cover plate 31 are connected with machine shell 2, and located above the roller brush 1.The lighting assembly 3 is located at the front end of scrubber 100, is configured to emit light towards the advancing direction of the roller brush 1, and the light emitted from the lighting assembly 3 is always located in front of the roller brush 1, to ensure that operator has good vision when operating the scrubber 100, to improve scrubbing effect in turn.
[0031] In the embodiment, the scrubber 100 is double-roller scrubber, the roller brush 1 includes front roller brush 11 and rear roller brush 12 arranged in front and back in advancing direction, the machine shell 2 is located above the rear roller brush 12 and at least partially covers the front roller brush 11, and the cover plate 31 is located above the front roller brush 11 and connected with the machine shell 2.Of course, in other embodiments, the roller brush 1 can be single-roller brush, which is not limited, and the lighting assembly 3 can also be assembled on the machine shell 2, which is also not limited, and only needs to ensure that the lighting assembly 3 is located above the machine shell 2 and emits light towards the advancing direction of the roller brush 1.
[0032] Preferably, the bottom of the machine shell 2 is concave upward to at least partially accommodate the roller brush 1.In the embodiment, the bottom of the cover plate 31 is concave and arranged to adapt to the roller brush 1, and forms a receiving cavity 20 together with the machine shell 2 to accommodate the roller brush 1.Of course, in other embodiments, the receiving cavity 20 can also be formed by the machine shell 2 alone.By setting the bottom of the cover plate 31 to be concave, the cover plate 31 is more adapted to the roller brush 1, so that the scrubber 100 as a whole is more beautiful.
[0033] Please combine Figures 3 to 5 As shown, in this embodiment, the lighting assembly 3 includes a light source 32 and a light guide 33 mounted on the cover plate 31. The cover plate 31 is configured to at least partially cover the roller brush 1. The light source 32 is embedded in the light source region 311 on the cover plate 31 to emit light toward the light guide 33. The light guide 33 is configured to perform total internal reflection on at least a portion of the light emitted by the light source 32 before it enters the cover plate 31 and finally exits from the light-emitting surface 3123 of the cover plate 31.
[0034] In the forward direction of the floor scrubber 100, the cover plate 31 is sequentially provided with a light source area 311, a light emission area 312, and an assembly area 313 formed between the light source area 311 and the light emission area 312. Optionally, the light emission area 312 is located near the front end of the floor scrubber 100, and the assembly area 313 and the light source area 311 are located at the rear end of the light emission area 312.
[0035] Please see Figure 5 As shown, Figure 5 The dashed arrow in the figure indicates the light emission direction of the lighting component 3. The light source 32 is embedded in the light source area 311 and emits light towards the assembly area 313. The light guide 33 is embedded in the assembly area 313 so that most of the light emitted by the light source 32 is totally internally reflected and then enters the light emission area 312, and then is emitted from the light emission area 312.
[0036] In this embodiment, both the light guide 33 and the cover plate 31 are made of optical-grade transparent materials such as PMMA or PC. This design makes the output light more transparent, which is more beneficial to the use of the floor scrubber 100. Of course, the application of the light guide 33 and the cover plate 31 is not limited to the floor scrubber 100, and can also be applied to other products. There is no limitation on this.
[0037] In this embodiment, the light guide 33 and the cover plate 31 are separately disposed. Of course, in other embodiments, the light guide 33 and the cover plate 31 can also be disposed as a single unit to form an integrated structure, and this is not a limitation here.
[0038] Preferably, both the light guide 33 and the light-emitting region 312 have specific incident and exit surfaces, and the remaining wall surfaces are total reflection surfaces. When light emitted from the light source 32 enters the interior of the light guide 33 through the incident surface, the light is reflected to the exit surface by the interaction of multiple total reflection surfaces within the light guide 33. Similarly, when light enters the interior of the light-emitting region 312 through the incident surface, the light is reflected to the exit surface by the interaction of multiple total reflection surfaces within the light-emitting region 312.
[0039] In the embodiment, the lower surface of the light emitting area 312 of the cover plate 31 is also concave, and a reflection surface 3124 matching the concave shape is arranged in the light emitting area 312, and the reflection surface 3124 is configured to totally reflect the light entering the light emitting area 312 to the light emitting surface 3123 for emission. Therefore, the concave shape of the lower surface of the light emitting area 312 can further adjust the reflection angle, which is more conducive to the emission of light.
[0040] The light emitting area 312 is provided with a light emitting surface 3123 located on the side of the cover plate 31 away from the light source 32, and forms an included angle with the extension line or tangent line of the lower surface of the cover plate 31, and the included angle is between 60°-90°. In this way, the light emitting surface 3123 is a bevel, so that the ground about 240mm in front of the scrubber 100 can be illuminated, and the ground can reach a certain brightness level and brightness uniformity, which is conducive to the operator to clean the ground.
[0041] Of course, in other embodiments, the light emitting direction of the illumination assembly 3 can be controlled according to the angle setting of the light emitting surface 3123. It should be noted that the 60°-90° selected in the embodiment is only suitable for the working of the scrubber 100, and when the illumination assembly 3 is arranged on other products, the bevel angle of the light emitting surface 3123 can be set according to the actual situation, and this is not limited.
[0042] Specifically, please refer to Figure 6 The first light expanding structure 331 is provided on one side of the light guide piece 33, and faces the light source 32 and is in mutual position with the light source 32, so that most of the light emitted by the light source 32 can be dispersed into the light guide piece 33.
[0043] The first light expanding structure 331 and the light source 32 not only correspond to each other in the setting position, but also correspond to each other in the specific number. Specifically, in the embodiment, the light source 32 is provided with a plurality of the first light expanding structure 331, and the projection of the geometric center of each light source 32 on the first light expanding structure 331 is located at the geometric center of the first light expanding structure 331, so that the light emitted by the light source 32 can be uniformly dispersed by the first light expanding structure 331 and introduced into the light guide piece 33. At the same time, it can also increase the coverage range when the light source 32 emits light, and ensure that most of the light can be uniformly introduced into the cover plate 31.
[0044] Optionally, the light guide 33 is further provided with a second light expansion structure 332 corresponding to the first light expansion structure 331, and in the advancing direction of the scrubber 100, the second light expansion structure 332 extends obliquely towards the light emitting area 312, and the light emitted from the light guide 33 is dispersed and introduced into the light emitting area 312.
[0045] The first light expansion structure 331 is arranged in a sawtooth shape, and the size of the first light expansion structure 331 is slightly larger than the size of the light source 32, so as to disperse and introduce as much light emitted by the light source 32 as possible into the light guide 33. The second light expansion structure 332 is an array of sawtooth structures corresponding to the light emitting area 312. The sawtooth arrangement makes the light expansion effect of the first light expansion structure 331 and the second light expansion structure 332 better, and can disperse the brightness of the light emitted by the light source 32, thereby reducing glare.
[0046] Specifically, the light emitting area 312 is provided with a light inlet portion 3121 protruding from the cover plate 31, the assembly area 313 is formed between the light inlet portion 3121 and the light source area 311, and the second light expansion structure 332 faces the light inlet portion 3121.
[0047] The light emitting area 312 is further provided with a light emitting portion 3122 opposite to the light inlet portion 3121. In the vertical direction perpendicular to the ground, the light emitting portion 3122 is lower than the light inlet portion 3121, and the light emitting portion 3122 extends obliquely towards the ground, so that the light entering the light emitting area 312 is emitted obliquely downward. The light emitting surface 3123 is formed on the light emitting portion 3122. In this way, the light emitting portion 3122 is arranged obliquely as a whole and corresponds to the light emitting surface 3123, and together they emit the light emitted by the illumination assembly 3 obliquely downward. Of course, according to actual needs, the inclination angle of the light emitting portion 3122 and the light emitting surface 3123 can be adjusted to control the direction of the light emitted by the illumination assembly 3, so as to meet the needs of the operator.
[0048] In summary, the scrubber 100 of the utility model forms an assembly area 313 between the light source area 311 and the light emitting area 312 of the cover plate 31, and assembles a light guide 33 in the assembly area 313, that is, the light guide 33 is arranged between the cover plate 31 and the light source 32, so that most of the light emitted by the light source 32 can be totally reflected by the light guide 33 and then enter the light emitting area 312 of the cover plate 31, and finally be emitted from the light emitting surface 3123 of the cover plate 31, achieving the effect of controlling the light emitting angle and being more practical.

Although the present application has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or equivalently replaced without departing from the spirit and scope of the technical solutions of the present application.
