Fig. 1 is a schematic diagram illustrating a surface cleaning apparatus 100 according to one embodiment of the invention. The surface cleaning apparatus 100 comprises an upright body 1 and a cleaning base 2. The surface cleaning apparatus 100 of this example is an upright hand-propelled cleaning apparatus in which the machine is held upright after use. The surface cleaning apparatus 100 is supported on and movable along a surface to be cleaned during cleaning of the surface to be cleaned by the cleaning base 2. The lower part of the upright body 1 is pivotally mounted to the cleaning base 2, the upright body 1 being rotatable relative to the cleaning base 2 between an upright rest position and a rearwardly inclined use position. The cleaning base 2 is provided at a front lower portion thereof with a rotatable cleaning roller 21. When the cleaning base 2 moves over the floor to be cleaned, the cleaning roller 21 agitates the floor to be cleaned to achieve friction with the floor to be cleaned. In other embodiments, the surface cleaning machine is not limited to an upright machine type, but may be a horizontal type, portable type, or the like.

The upright body 1 is provided at a top portion thereof with a handle portion 11 for a user to grasp and at a lower portion thereof with a battery pack 12. The handle portion 11 includes an arcuate handle 111. The operator can grasp the surface cleaning apparatus 100 with one hand by using the arcuate handle 111 and thereby push the cleaning base 2 of the surface cleaning apparatus 100 to move back and forth on the surface to be cleaned in a state of being tilted backward. In this example, the handle 111 is further provided with a human-machine interface 5, where the human-machine interface 5 is mainly used for transmitting the current working condition of the device 100 to the user, such as warning information that the user needs to get rid of obstacles, and displaying working parameter information of some working units on the device. In this case, the upright body 1 is further provided with a control unit 6 comprising a plurality of operating elements 61, which operating elements 61 may be, for example but not limited to, buttons, triggers, switches, etc., by means of which the surface cleaning apparatus 100 is able to control the operation of all controlled working parts of the surface cleaning apparatus, such as the opening and closing of the apparatus, the regulation of the flow of cleaning liquid, the self-cleaning of the apparatus after a stoppage, etc. In this case, these operating elements are mostly provided at the handle 111. In other embodiments, the human-machine interface and the operating element may also be provided elsewhere in the surface cleaning apparatus, such as on a top wall or side wall of the body in the lower portion of the handle.

As shown in fig. 2, a cleaning liquid supply system unit and a dirty liquid recovery system are disposed on the surface cleaning apparatus 100. And the cleaning liquid supply system is used for storing and supplying the cleaning liquid to the outside. The cleaning liquid supply unit includes a cleaning liquid supply tank 31 for storing the cleaning liquid, an infusion pump 32, a nozzle 33, and necessary cleaning liquid piping. The infusion pump 32 of the present example is configured to be able to operate in both high and low gear under the control of the control unit 6. The contaminated liquid recovery system is used for removing the contaminated liquid converted from the used cleaning liquid and the solid waste located on the surface to be cleaned from the surface to be cleaned, and storing the contaminated liquid and the solid waste for a certain time. The contaminated liquid recovery system includes a contaminated liquid recovery tank 41 for storing contaminated liquid and solid waste for a certain period of time, a suction motor 42, and necessary contaminated liquid piping.

As further shown in fig. 2, in order to monitor and manage the individual working units on the surface cleaning apparatus 100, a monitoring unit is provided on the surface cleaning apparatus 100 in addition to the human-machine interface 5 and the operating element 61 described above. The monitoring unit of the present example comprises several sensors and monitoring circuits arranged at the respective working units in the surface cleaning apparatus 100. The method comprises the following steps: a first sensor 71 is arranged in the cleaning liquid supply system, the first sensor 71 senses the operation state of the cleaning liquid supply system, for example, whether the cleaning liquid continuously passes through the cleaning liquid pipeline or not, and the control unit can judge whether the cleaning liquid supply tank 31 is in a water shortage state or whether the cleaning liquid supply tank 31 is in place or not through the signal sensed by the first sensor 71; in other embodiments, the first sensor 71 may also be disposed within the cleaning liquid supply tank 31 to monitor the liquid level within the cleaning liquid supply tank 31. The second sensor 72 is disposed in the dirty liquid recovery tank 41, and the second sensor 72 can sense an operation state of the dirty liquid recovery tank 41, such as whether the dirty liquid recovery tank 41 is full of liquid, whether the dirty liquid recovery tank 41 needs to be toppled over, whether the dirty liquid recovery tank 41 is installed in place, and the like. The surface cleaning apparatus 100 is further provided with a rotation speed monitoring circuit 73 for monitoring the rotation of the cleaning roller 21 and a power monitoring circuit 74 for monitoring the power of the battery pack 12, which are usually used for indirectly obtaining the target parameter information by judging the current or voltage value of the part to be tested.

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

The plurality of warning lamps in this example include a first warning lamp 521 for warning the user of the lack of liquid or improper installation of the cleaning liquid supply tank 31, a second warning lamp 522 for warning the user of the full liquid or improper installation of the dirty liquid recovery tank 41, and a third warning lamp 523 for warning the user of the improper rotation or improper installation of the cleaning roller 21 on the cleaning base 2. The plurality of parameter lamps includes a first parameter lamp 524 for showing the current amount of the battery pack to the user, and a second parameter lamp 525 for showing the current operation of the infusion pump according to the high-end execution.

The color of the external display of the parameter lamps when the parameter lamps are lighted is different from the color of the external display of the alarm lamps when the parameter lamps are lighted. The enhanced light emitting portion 54 is configured to emit a first light having the same color as the plurality of warning lamps to the outside when one or more of the warning lamps are lit on the human-machine interface 5 in response to the lit warning lamps and emit a second light having the same color as the plurality of

parameter lamps

524 and 525 to the outside when none of the warning lamps are lit on the human-machine interface 5; the effective light emitting area of the enhanced light emitting portion 54 is larger than the effective light emitting area of any one of the warning lamps.

As further shown in fig. 3, the control unit 6 further comprises a control board 62 for executing commands of the operating element 61. In order to achieve the display effect of the human-computer interface 5, the warning light and the parameter light, 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 turned on or off under the control of the control board 62, so that the control of the warning light and the parameter light is achieved. The human-computer interface 5 further includes a light shield 51 composed of a transparent cover 511 and a sticker layer 512 coated on an outer surface of the transparent cover 511, the light shield 51 being coated on an outer side of the control board 62. The light shield 51 includes a plurality of different patterned transparent regions 501 and annular transparent regions 502 located at the periphery of the different patterned transparent regions, and the different patterned transparent regions 501 are in one-to-one correspondence with a plurality of warning lamps or parameter lamps. At least 1 light emitting element 52 is integrated on the control board 62 inside several different patterned light transmitting regions 501, respectively; 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 are arranged on the corresponding control board 62 along the annular direction alternately on the inner side of the annular 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 that of the extension of the warning lamp, and the color of the second light is consistent with that of the parameter lamp. Thus, the control board 62 can only control the plurality of light emitting elements emitting the first light to illuminate so as to transmit the annular light-transmitting area 502, so that the enhanced light emitting portion 54 emits the first light to the outside, and a warning lamp responding to the illumination is realized; it is also possible to control only the light emitting element emitting the second light to illuminate so as to transmit the annular light-transmitting area 502, so that the enhanced light emitting portion 54 emits the second light to the outside, so as to inform the user that the current device is in the normal working process.

For the color design of the warning light and the parameter light, for example, the warning light can be designed to be in red which is easy to draw attention, and the first light emitted by the corresponding enhancement emission part is also in red; and the color of the parameter lamp and the second light rays emitted by the corresponding increasing light-emitting part is designed to be blue. In distinguishing between different warning lights and different parameter lights, it is possible to achieve a patterned light-transmitting region 501 of different patterns.

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 are lighted under the control of the control unit 6 during the operation of the surface cleaning apparatus 100 of this example, the enhanced light emitting portion 54 will be lighted simultaneously in response to these lighted warning lights, and the first light emitted by the enhanced light emitting portion 54 is consistent with the light color emitted by the warning lights; as shown in fig. 5, the first warning lamp 521 is turned on at this time, and the enhanced light emitting portion 54 is turned on at the same time, and the colors of the two lights are the same. When the man-machine interface 5 is not lighted by any warning light, 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 lighted, the enhanced light emitting portion 54 emits the second light of the other color. The parameter lamp of this example will light up with the actual situation, irrespective of whether the warning lamp and the enhanced light emitting portion are lit up or not.

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

The above embodiments are provided to illustrate the technical concept and features of the present invention and are intended to enable those skilled in the art to understand the content of the present invention and implement the same, and are not intended to limit the scope of the present invention. All equivalent changes or modifications made in accordance with the spirit of the present invention should be construed to be included in the scope of the present invention.
