Wherein, a power switch 50a is disposed on the hand-held portion of the upright handle 50, and a rotary contact switch 180 is disposed at the rotary connection position between the base 100 and the upright handle 50. After the power switch 50a is turned on, in the process that the upright handle 50 rotates from the initial state shown in fig. 4 to the use state shown in fig. 5, the rotary touch switch 180 is turned on, and at the same time, the rolling brush motor, the liquid pumping module and the sterilization module 200 all start to work under the control of the rotary touch switch 180, that is, at this time, the liquid pumping module can spray the cleaning liquid in the clean water tank 30 on the surface of the rolling brush 170, the rolling brush 170 sprayed with the cleaning liquid can automatically roll under the driving of the rolling brush motor to realize the automatic cleaning of the surface to be cleaned, the vacuum suction source can generate suction force to suck the dirt after brushing into the sewage tank 40, and meanwhile, the sterilization module 200 can also sterilize and disinfect the current cleaning area. Therefore, the cleaning equipment can clean visible dirt on the surface to be cleaned and sterilize and disinfect invisible harmful bacteria and viruses and the like on the current surface to be cleaned and in a certain range of the area to be cleaned around the current surface to be cleaned. Here, the power-on circuit of the sterilization module 200 refers to a power-on circuit between the sterilization module 200 and the battery pack, and the power switch 50a and the transfer switch 180 are electrically connected to the power-on circuit in series.

Optionally, as shown in fig. 1 and 3, the front and rear ends of the base structure 10 are respectively provided with a front roller 130 and a rear roller 140, so as to facilitate the cleaning device to walk on the surface to be cleaned. The front rollers 130 are distributed near the rolling brush 170, and the rear rollers 140 are disposed at the connection between the body 20 and the base 100, preferably, the number of the front rollers 130 and the number of the rear rollers 140 are 2, and the front rollers and the rear rollers are symmetrically disposed with respect to the central axis of the body 20, so as to ensure the stable walking of the whole cleaning apparatus. It should be noted that all references to "front", "rear", "left" and "right" orientations refer to those shown in fig. 4.

As an example, the sterilization module 200 may perform sterilization using ultraviolet rays. The specific structure of the sterilization module 200 is described below, and will not be described here.

As an example, as shown in fig. 3 and 6, the base 100 includes an upper cover 150 and a lower cover 160, the roller brush motor and the liquid extracting module are disposed in a space enclosed by the upper and lower covers 160, the sterilizing module 200 and the protecting module 300 are disposed on the lower cover 160, and the roller brush 170 is rotatably disposed on the upper cover 150 and exposed to an opening of the lower cover 160.

As described above for the base structure 10 of the cleaning device, when the light shielding member 310 is disposed on the surface to be cleaned, the control switch 320 can turn on the sterilization module 200, and then in the process of sterilizing the surface to be cleaned by the sterilization module 200, the light shielding member 310 can be disposed around the sterilization module 200 to place the sterilization module 200 in a relatively closed space through the cooperation with the surface to be cleaned, so that the sterilization light leaked from the sterilization module 200 to the outside of the base structure 10 can be effectively blocked even when the light shielding member 310 is not away from the surface to be cleaned; in addition, once at least a portion of the light-shielding member 310 leaves the surface to be cleaned and moves in a direction close to the surface to be cleaned, the operating state of the corresponding control switch 320 is adjusted from an on state to an off state, so as to turn off the sterilization module 200, thereby preventing the sterilization light generated by the sterilization module 200 from leaking out through a gap between the light-shielding member 310 and the surface to be cleaned, and providing a real health guarantee for the environment after cleaning.

In some embodiments of the present invention, as shown in fig. 7 and 8, the light shielding member 310 includes: the first shading plate 311, the second shading plate 312 and the third shading plate 313 are connected in sequence, the second shading plate 312 is distributed near the rear end of the base 100 and extends along the width direction of the base 100, and the first shading plate 311 and the third shading plate 313 extend along the length direction of the base 100. The longitudinal direction of the chassis 100 refers to a direction from the front side to the rear side of the chassis 100 or a direction from the rear side to the front side of the chassis 100, and the width direction of the chassis 100 refers to a direction from the left side to the right side of the chassis 100 or a direction from the right side to the left side of the chassis 100. The light shading member 310 has a simple structure and is convenient to prepare and produce.

Further, as shown in fig. 7 and 8, a protective strip 314 that can be pressed and deformed is disposed at a lower end of the second light shielding plate 312, the protective strip 314 and the second light shielding plate 312 extend in the same direction, and a lower surface of the protective strip 314 is flush with lower surfaces of the first light shielding plate 311 and the third light shielding plate 313. The lower surfaces of the guard bar 314, the first light shielding plate 311, and the third light shielding plate 313 refer to the lower surfaces of the guard bar 314, the first light shielding plate 311, and the third light shielding plate 313 when the cleaning apparatus is in normal operation. When meeting an obstacle, the protection strip 314 can deform to prevent the light-shielding member 310 from being damaged, thereby playing a role in protection. Alternatively, the protective strip 314 may be made of a hard plastic material (e.g., rubber), and the protective strip 314 may be formed on the second light shielding plate 312 by bonding, integral molding (e.g., injection molding), or the like. Alternatively, the first light shielding plate 311 and the third light shielding plate 313 may be made of a hard plastic material, such as PP (Polypropylene), which can prevent excessive friction between the base structure 10 and the surface to be cleaned, and the second light shielding plate 312 may be made of the same material as the first light shielding plate 311 and the third light shielding plate 313.

On the premise that the light shielding member 310 includes the first light shielding plate 311, the second light shielding plate 312 and the third light shielding plate 313, it is specific to some embodiments of the present invention that the number of the control switches 320 is 4, 2 control switches 320 are respectively disposed in the middle of the first light shielding plate 311 and the third light shielding plate 313, and 2 control switches 320 are respectively disposed at the left and right ends of the second light shielding plate 312. By arranging the control switches 320 in this way, the number of the control switches 320 can be reduced as much as possible on the premise of ensuring that the protection module 300 has a certain sensitivity, thereby reducing the cost of the base structure 10. Optionally, the 2 control switches 320 are symmetrical about the central axis of the base 100.

In some embodiments of the present invention, as shown in fig. 3, 7 and 8, the protection module 300 further includes at least one elastic member 330, and the elastic member 330 is connected to the base 100 and the light shielding member 310; the elastic member 330 serves to provide a force to the light-shielding member 310 to move toward the surface to be cleaned when at least a portion of the light-shielding member 310 is spaced apart from the surface to be cleaned. Once the light shielding member 310 leaves the surface to be cleaned, the light shielding member 310 can rapidly move towards the surface to be cleaned under the action of the elastic member 330, so that the control switch 320 can be rapidly turned off, and the sensitivity of the protection module 300 is improved.

It can be understood that the number and the arrangement position of the elastic members 330 are the same as those of the control switch 320, that is, the elastic members 330 correspond to the control switch 320 one by one, for example, as shown in fig. 7 and 8, the number of the elastic members 330 is 4, 2 elastic members 330 are respectively distributed in the middle of the first light shielding plate 311 and the third light shielding plate 313, and 2 elastic members 330 are disposed at the left and right ends of the second light shielding plate 312 and are symmetrical with respect to the central axis of the base 100.

Alternatively, as shown in fig. 4, a receiving groove is provided on the lower cover 160 of the base 100, and one end of the elastic member 330 is mounted in the receiving groove. And a receiving groove which may function to fix the elastic member 330. As an example, when the control switch 320 is set as a mechanical control switch, the receiving groove is opened on the contacting part 110; (ii) a When the light shielding member 310 is disposed on the surface to be cleaned, the contact 321 of the control switch 320 is separated from the contact part 110 of the base 100, and when at least a part of the light shielding member 310 is separated from the surface to be cleaned, the corresponding contact 321 of the control switch 320 can be abutted against the contact part 110 of the base 100. The elastic element 330 can be installed in the receiving groove of the contacting portion 110 in an interference fit manner. It can be understood that the number and the arrangement position of the contacting portions 110 of the base 100 are the same as those of the elastic members 330, that is, the elastic members 330 correspond to the contacting portions 110 one by one, for example, the number of the contacting portions 110 is 4, 2 contacting portions 110 are respectively distributed in the middle of the first light shielding plate 311 and the third light shielding plate 313, and 2 contacting portions 110 are distributed at the left and right ends of the second light shielding plate 312 and are symmetrical about the central axis of the base 100.

Alternatively, as shown in fig. 3, the light shielding member 310 is provided with at least one mounting post 315, and the other end of the elastic member 330 is sleeved on the corresponding mounting post 315. The contact part 110 of the base 100 and the mounting post 315 are matched to realize the detachable connection between the light shielding member 310 and the base 100. The elastic member 330 can be sleeved on the mounting post 315 in an interference fit manner. Regarding the shape of the mounting post 315, it may be a polished rod structure or a cross-shaped structure as shown in fig. 3, and the embodiment of the present invention is not particularly limited. It can be understood that the number and the arrangement position of the mounting posts 315 are the same as those of the elastic member 330, that is, the mounting posts 315 correspond to the elastic member 330 one by one, for example, the number of the mounting posts 315 is 4, 2 mounting posts 315 are respectively distributed in the middle of the first light shielding plate 311 and the third light shielding plate 313, and 2 mounting posts 315 are distributed at the left and right ends of the second light shielding plate 312 and are symmetrical about the central axis of the base 100.

In some embodiments of the present invention, as shown in fig. 3, the housing 322 of the control switch 320 is provided with at least one connection ear plate 323 extending toward the light-shielding member 310; as shown in fig. 3, 7 and 8, the light shielding member 310 is provided with at least one stud 316 extending toward the control switch 320, and the stud 316 is connected to the corresponding connection lug 323 by a screw. This facilitates replacement of the control switch 320 and the light shielding member 310. With respect to the number and distribution positions of the connecting ear plates 323, the embodiment of the present invention is not particularly limited, for example, the number of the connecting ear plates 323 is 2, and 2 connecting ear plates 323 are symmetrically distributed on two sides of the contact 321 of the control switch 320, so that the light shielding member 310 and the control switch 320 can be effectively and firmly connected. In addition, the number and the distribution positions of the studs 316 are related to not only the connecting lug plate 323 but also the number and the distribution positions of the control switches 320, for example, as shown in fig. 6 and 7, the number of the studs 316 is 8, 2 studs 316 are distributed in the middle of the first light shielding plate 311, 2 studs 316 are distributed in the middle of the third light shielding plate 313, and 4 studs 316 are symmetrically distributed at the left and right ends of the second light shielding plate 312 about the central axis of the base 100.

In some embodiments of the present invention, as shown in fig. 3, 7 and 8, the protection module 300 further includes at least one rolling member 340, and the rolling member 340 is rotatably disposed on the light shielding member 310. As an example, the lower surface of the rolling member 340 is flush with the lower surface of the light blocking member 310. The rolling member 340 can reduce the friction between the shading member 310 and the surface to be cleaned, which is beneficial to the walking of the cleaning device. It is understood that, as shown in fig. 8, the rolling member 340 is mounted to the light blocking member 310 through the rotation shaft 341.

Alternatively, the rolling member 340 may be a roller. In addition, as shown in fig. 7 and 8, the number of the rolling members 340 is 4, and the 4 rolling members 340 are symmetrically arranged at the left and right ends of the light shielding member 310 with respect to the central axis of the base 100. Thus, the cleaning equipment can walk more smoothly. As an example, 2 rolling members 340 are respectively disposed at the front ends of the first light shielding plate 311 and the third light shielding plate 313 of the light shielding member 310, and 2 rolling members 340 are respectively disposed at the junction between the first light shielding plate 311 and the second light shielding plate 312 of the light shielding member 310 and the junction between the third light shielding plate 313 and the second light shielding plate 312.

As for the manner how the control switch 320 opens and closes the sterilizing module 200, (3) manners are given as follows:
