As shown in fig. 2-4, the human-machine interface 5 includes warning lights for reminding the user that the surface cleaning device is in an abnormal state, parameter lights for showing the operating parameters of the surface cleaning device to the user, and an annular enhanced light emitting unit 54. The enhanced light emitting portion 54 surrounds the plurality of warning lamps and the plurality of parameter lamps. The enhanced light emitting section 54 is ring-shaped and arranged at a position near the outer edge of the human-machine interface 5. Two operation elements 61 in the control unit 6 are also located inside the enhanced light emitting section 54.

The warning lights in this example include a first warning light 521 for warning the user that the cleaning liquid supply tank 31 is out of liquid or improperly mounted, a second warning light 522 for warning the user that the dirty liquid recovery tank 41 is full of liquid or improperly mounted, and a third warning light 523 for warning the user that the cleaning roller 21 on the cleaning base 2 is not rotating properly or is improperly mounted. The parameter lamps comprise a first parameter lamp 524 used for displaying the current electric quantity of the battery pack for a user and a second parameter lamp 525 used for displaying the current operation of the infusion pump according to high grade for the user.

The colors displayed by the parameter lamps when the parameter lamps are turned on are different from the colors displayed by the warning lamps when the warning lamps are turned on. The enhanced light emitting portion 54 is configured to emit a first light having the same color as the plurality of warning lamps when one or more warning lamps on the human-computer interface 5 are on, in response to the plurality of warning lamps being on, and emit a second light having the same color as the plurality of

parameter lamps

524 and 525 displayed when the plurality of parameter lamps are on, when none of the warning lamps on the human-computer interface 5 are on; the effective light emitting area of the enhanced light emitting portion 54 is larger than that of any one of the warning lamps.

As further shown in fig. 3, the control unit 6 also comprises a control board 62 for executing commands of the operating elements 61. In order to achieve the display effect of the human-machine interface 5, the warning lamp and the parameter lamp and the light emitting elements 52 of the enhanced light emitting part (in this example, the light emitting elements are composed of LED lamps with different colors) are all integrated on the control board 62 of the control unit 6, and the light emitting elements 52 are controlled to be turned on or off by the control board 62, so that the control of the warning lamp and the parameter lamp is realized. The human-machine interface 6 further comprises a light shield 51 composed of a transparent cover body 511 and a paper-attached layer 512 covering the outer surface of the transparent cover body 511, and the light shield 51 covers the outer side of the control panel 62. The light shield 51 includes a plurality of different patterned transparent areas 501 and an annular transparent area 502 located at the periphery of the plurality of different patterned transparent areas, and the plurality of different patterned transparent areas 501 correspond to a plurality of warning lamps or parameter lamps one to one. At least 1 light-emitting element 52 is integrated on the control board 62 inside the plurality of different patterned light-transmitting regions 501; the luminous color of the luminous element corresponding to the warning lamp is different from the luminous color of the luminous element corresponding to the parameter lamp. Two kinds of light emitting elements which are alternately distributed along the ring shape are arranged on the corresponding control board 62 at the inner side of the ring-shaped light-transmitting area 502, wherein one kind of light emitting element can emit first light, the other kind of light emitting element can emit second light, the color of the first light is consistent with the extension of the warning lamp, and the color of the second light is consistent with the color of the parameter lamp. Thus, the control board 62 can only control the plurality of light emitting elements emitting the first light to light up so as to transmit the first light to the outside through the annular light transmitting area 502, so as to implement response to the lighted warning light; it is also possible to control only the light emitting element emitting the second light to light up to penetrate the annular light-transmitting area 502, so that the enhanced light emitting portion 54 emits the second light to the outside to inform the user that the device is in the normal working process.

For the color design of the warning lamp and the parameter lamp, for example, the warning lamp can be designed to emit red which is easy to attract attention, and the first light emitted by the corresponding enhanced emission part is also red; the color of the parameter lamp and the second light emitted by the corresponding increased light emitting part is designed to be blue. When distinguishing different warning lights and different parameter lights, the light-transmitting regions 501 can be patterned by different patterns.

When the surface cleaning device 100 of this example is in operation, when any one or more of the first warning light 521, the second warning light 522 and the third warning light 523 in the human-machine interface 5 is/are turned on under the control of the control unit 6, the enhanced light-emitting part 54 will be turned on at the same time to respond to the turned-on warning lights, and the first light emitted by the enhanced light-emitting part 54 is in the same color as the light emitted by the warning lights; as shown in fig. 5, at this time, the first warning lamp 521 is turned on, and the enhancement light emitting portion 54 is simultaneously turned on, and the colors of the two lights are the same. When the human-computer interface 5 is not lighted, the enhanced light emitting part 54 emits a second light with another color to inform the user that the current equipment is in a normal working state; as shown in fig. 6, when none of the first warning lamp 521, the second warning lamp 522, and the third warning lamp 523 is turned on, the enhanced light emitting portion 54 emits the second light of another color. The parameter lamp of this example will light up as the case may be, regardless of whether the warning lamp and the accent lighting portion are lit.

According to the man-machine interface design, the enhanced light-emitting part with a larger effective light-emitting area is additionally arranged, so that a user can perceive the equipment at the first time when the equipment in work is in abnormal conditions such as failure or unavailability, and the like, and the normal use of the equipment is guaranteed for the user; compared with the liquid crystal display screen and the OLED display screen which are widely popular at present, the design scheme is lower in price and is convenient for reducing the manufacturing cost of equipment.

The above embodiments are merely illustrative of the technical ideas and features of the present invention, and the purpose thereof is to enable those skilled in the art to understand the contents of the present invention and implement the present invention, and not to limit the protection scope of the present invention.
