An alternative embodiment of the present invention is described in detail below with reference to the drawings.

Cleaning devices, in particular cleaning robots, are often provided with touch or physical buttons on the visible outer surface in order to input user commands via the buttons to a control system of the cleaning device, which carries out corresponding tasks, for example, starting cleaning, returning piles, etc., depending on the user input.

As shown in fig. 1, the cleaning robot includes a panel 3 and a key sheet 1 protruding or flush or recessed through the panel 3, and illustratively, three keys are provided on the key sheet 1 to implement different functions, respectively. Of course, the cleaning robot also comprises a frame which is formed into a frame for bearing other components, wherein a cleaning component, a fan component, a dust box, a battery component, a driving wheel component and the like are arranged in the frame, and all the components are respectively arranged in different spaces on the frame according to functions; the panel 3 is covered on the upper part of the rack, which can be called as a decorative plate, and can encapsulate each component in the rack accommodating space, so that the panel 3 can be opened integrally or separately, generally, the dust box can be taken out for cleaning by opening the integrally or separately opened panel 3, and it can be understood that the integrally or separately opened panel 3 described above can be pivotally mounted on the rack in a hinged manner, so that the user can open the panel 3 more conveniently for subsequent operations.

Fig. 2 to 3 show a longitudinal sectional view and a partially enlarged view of the key sheet 1 in fig. 1.

Fig. 4 shows a rear view of the key sheet 1, the key sheet 1 being made of a flexible material as a whole, and a plurality of locking buttons are provided thereon to connect the key sheet to the chassis or the light panel 2 in a sealing manner. The key sheet 1 is provided with at least one key, three keys in this embodiment, each key is provided with a character transmitting area 31, and ribs are formed between the keys to divide the three keys into a plurality of spaces in form, that is, the spaces are formed by the ribs, the periphery of the key sheet 1, and the bottom surfaces 41 of the keys. The ribs can be flush with the periphery of the key board 1, and the keys are higher than the ribs when viewed from the back of the key board 1, so that three-dimensional spaces are formed in the areas where the three keys are located respectively. White reflecting layers, specifically white silk screen printing and the like, are respectively sprayed on the peripheral inner wall of the key board 1, the side wall of the rib and the bottom surface 41 of the key.

Fig. 5 shows the configuration and structure of a lighting panel on which the same number of dome switches 11 as the number of keys on the key panel 1 are provided, and one or more LED lamps 21 are arranged on the periphery of each dome switch 11 for lighting when the dome switch 11 of the lamp accessory is pressed, or capable of lighting when necessary. A light panel upper plate 51 is formed in the area where the dome switch 11 is located on the light panel 2, the light panel upper surface 51 covers all the dome switches 11 and the LED lamps 21, and a white reflective layer is also sprayed on the light panel upper surface, and the white reflective layer may be a white screen printing or a paint spraying.
