In the following embodiments, the descriptions of the embodiments are focused on, and for the part that is not described in detail in a certain embodiment, reference may be made to the related descriptions of other embodiments.

Referring to fig. 1, fig. 1 is a schematic structural diagram of a base station of a cleaning device according to an embodiment of the utility model.

In an embodiment, the cleaning device may be a cleaning apparatus such as a cleaning robot, the cleaning device being capable of moving on the cleaning surface by itself, the cleaning device being capable of cleaning an area through which it passes. Of course, in other embodiments of the present utility model, the cleaning device may be a cleaning apparatus such as a washer, a floor washer, or the like, and the user may clean the area through which the cleaning device passes by holding the cleaning device and pushing the cleaning device over the cleaning surface. The cleaning surface may be the floor or the surface of the article to be cleaned. The embodiments of the present utility model are illustrated by way of example and not limitation as being required by the discussion.

The cleaning device is used in cooperation with the base station 10, and the base station 10 is used for assisting the cleaning device in cleaning work. For example, cleaning devices are typically equipped with cleaning elements such as wipes, roller brushes, mops, and the like, to clean the cleaning surface. The cleaning device is returned to the base station 10, and the cleaning elements on the cleaning device are cleaned by the base station 10 so that the cleaning elements can be reused for the next cleaning operation. Of course, the base station 10 may also be used to charge a cleaning device, etc., and is not limited herein.

The base station 10 according to the embodiment of the present utility model is explained below.

Referring to fig. 2, fig. 2 is a schematic diagram illustrating a back structure of a base station according to an embodiment of the cleaning apparatus of the utility model.

In one embodiment, the base station 10 includes a base station body 11. The base station body 11 serves as a base carrier of the base station 10 for carrying and protecting the remaining components of the base station 10. Specifically, the base station main body 11 has a dirt collecting tank 111, and the dirt collecting tank 111 is used for collecting dirt from the cleaning device. For example, after the cleaning device is returned to the base station 10, the cleaning elements on the cleaning device are washed in the dirt collecting tank 111, and the dirt washed off is collected in the dirt collecting tank 111; alternatively, after the cleaning device is returned to the base station 10, the dirt recovered by the cleaning device during the cleaning process is poured into the dirt collecting tank 111 to empty the dirt storage space inside the cleaning device so as to perform the next cleaning operation. The embodiments of the present utility model are described by taking the example of the dirt collection tank 111 for collecting dirt washed from the cleaning elements of the cleaning apparatus, which is only for discussion purposes and is not limiting.

The base station 10 further includes a recovery unit 12, and the recovery unit 12 is disposed on the base station body 11. The dirt from the cleaning device is recovered by the recovery unit 12, and specifically, the dirt collected in the dirt collection tank 111 is recovered by the recovery unit 12. Specifically, recovery assembly 12 includes a tank 122 and a recovery tube 121. The recovery pipe 121 is connected to the sewage collection tank 111, and the sewage storage tank 122 is connected to the recovery pipe 121, whereby the sewage in the sewage collection tank 111 is recovered to the sewage storage tank 122 through the recovery pipe 121. The dirt storage tank 122 is used for storing dirt recovered by the base station 10, and a user can clean the dirt storage tank 122 periodically, or the base station 10 can clean the dirt storage tank 122 by itself.

The base station 10 further includes a detection assembly 20, the detection assembly 20 being disposed on the recovery assembly 12. The detection assembly 20 is used to detect the degree of contamination of the contaminants recovered by the recovery assembly 12. The soil level characterizes the soil level of the detected soil. Specifically, the detecting component 20 is disposed on the recovery tube 121 to detect the dirt degree of the dirt recovered by the recovery tube 121. For example, the recovery pipe 121 includes a first sub-pipe 123 and a second sub-pipe 124, the first sub-pipe 123 connects the dirt collecting tank 111 with the detection assembly 20, and the second sub-pipe 124 connects the detection assembly 20 with the dirt storing tank 122. The dirt in the dirt collection tank 111 is recovered through the first sub-pipe 123, the dirt passing through the dirt collection tank is detected by the detection assembly 20, and the dirt passing through the detection assembly 20 is recovered to the dirt storage tank 122 through the second sub-pipe 124.

It should be noted that, after the floor sweeping machine in the prior art finishes mopping, the floor sweeping machine returns to the base station 10 to clean the rag. The number of cleaning operations of the wipe is generally fixed. However, under the condition that the ground is dirty, the cleaning cloth is seriously polluted, the cleaning cloth cannot be cleaned by fixed cleaning times, if the cleaning cloth which is not cleaned is continuously used for cleaning the ground, secondary pollution to the ground can be caused, and the cleaning effect of the ground is poor. Moreover, in the case of dirty ground (such as barren and clean new houses), the sweeper cannot always ensure that the ground is cleaned at one time. The sweeper needs to be repeatedly mopped for two times, and even three times can be cleaned. The cleaning logic of the sweeper is usually a fixed number of cleaning times of each room, and the cleaning times of each room are mainly set by a user in an APP (Application program), which results in that the user needs to intervene in the working process of the sweeper deeply, which means that the degree of intellectualization of the sweeper is low, and the cleaning work cannot be completely managed to the sweeper.

In view of this, the base station 10 of the present embodiment detects the degree of dirt washed from the cleaning elements of the cleaning device by providing the detecting means 20. Specifically, the base station 10 cleans the cleaning elements of the cleaning device using a cleaning medium such as clean water, and the generated sewage is collected in the sewage collecting tank 111, and the sewage in the sewage collecting tank 111 is recovered to the sewage storage tank 122 through the recovery pipe 121. The sewage may pass through the sensing assembly 20 during the recovery process to sense the degree of contamination of the sewage by the sensing assembly 20. On the one hand, the sewage reflects the dirt degree of the cleaning elements on the cleaning device, and the detection assembly 20 can judge whether the cleaning elements are cleaned or not by detecting the dirt degree of the sewage, so that the cleaning times of the cleaning elements are controlled to be increased or decreased to ensure that the cleaning elements are cleaned; on the other hand, the dirty water also reflects the dirty degree of the cleaning surface (the dirty water generated by cleaning the cleaning element is dirty more when the cleaning surface is dirty), and the detecting assembly 20 can determine whether the cleaning surface is clean or not by detecting the dirty degree of the dirty water, so as to control the increase or decrease of the cleaning times of the cleaning surface, so as to ensure that the cleaning surface is clean.

In this way, the base station 10 of the present embodiment can ensure the cleaning effect of the cleaning elements on the cleaning device and the cleaning effect of the cleaning surface by providing the detection unit 20. According to the embodiment, the cleaning device is controlled to drag and sweep the cleaning surface in real time through the program, a user does not need to set the cleaning times of the cleaning elements and the cleaning times of the cleaning surface, so that the thinking logic of the user is lightened, the use is more convenient, the interaction experience between the user and the cleaning device and between the user and the base station 10 is better, even the user can completely host the cleaning work to the cleaning device, and the intelligent hosting of the cleaning work is realized.

The detection assembly 20 of an embodiment of the present utility model is described below.

Referring to fig. 3 to 6, fig. 3 is a schematic structural diagram of an embodiment of the detection assembly of the present utility model, fig. 4 is a schematic exploded structural diagram of the detection assembly shown in fig. 3, fig. 5 is a schematic sectional structural diagram of the detection assembly shown in fig. 3, and fig. 6 is a schematic structural diagram of an embodiment of the cap and the light shielding body of the present utility model.

In one embodiment, the detection assembly 20 includes a body 21. The body 21 is a basic carrier of the detection assembly 20, and the body 21 plays a role in bearing and protecting the rest parts of the detection assembly 20. Wherein the body 21 has a receiving cavity 211. The detection assembly 20 further includes a light shield 22. The light shielding body 22 is protruding on the inner wall surface of the body 21 facing the accommodating cavity 211, and the light shielding body 22 encloses to form a light shielding cavity 221. The detection assembly 20 further comprises a detection element 23. At least part of the detecting element 23 is accommodated in the light shielding cavity 221, and the detecting element 23 is used for detecting the dirt degree of dirt recovered by the recovery assembly 12.

In this way, the independent light path (i.e. the light shielding cavity 221) is designed for the detection element 23, the light shielding body 22 can shield the light of the external environment, prevent the light of the external environment from entering the light shielding cavity 221, and avoid the light crosstalk phenomenon between the light of the external environment and the light transmitted by the detection element 23, i.e. stray light, so as to improve the accuracy of detecting the dirt degree by the detection element 23.

Specifically, the detection assembly 20 further includes a detection tube 25. The detection pipe 25 is connected to the recovery unit 12, and the dirt recovered by the recovery unit 12 passes through the detection pipe 25. The sewage collecting tank 111 is connected to the detection pipe 25 through a first sub-pipe 123, and the detection pipe 25 is connected to the sewage storage tank 122 through a second sub-pipe 124. The body 21 includes a sleeve 215 and a base. The sleeve 215 is fitted over the outer periphery of the detection tube 25. The wall of the sleeve 215 is provided with a light-transmitting through hole 216, the light-transmitting through hole 216 is arranged opposite to the light-shielding cavity 221, and the detecting element 23 detects the dirt degree of dirt passing through the detecting tube 25 through the light-transmitting through hole 216. The light signal transmitted by the detection element 23 passes through the light-transmitting through hole 216, and stray light can be eliminated. The base is disposed around the outer periphery of the sleeve 215, and has the accommodating cavity 211. The base includes a base 213 and a cap 214, the cap 214 is abutted with the base 213 to form a containing cavity 211, and the light shielding body 22 is protruding on an inner wall surface of the cap 214 facing the containing cavity 211. The sleeve 215 and the base 213 may be of unitary construction.

In one embodiment, the sensing element 23 is divided into at least two sets of element combinations 231. Each element combination 231 includes a light emitting element 232 and a light receiving element 233. The light emitting element 232 and the light receiving element 233 of each element combination 231 are located on opposite sides of the sleeve 215, respectively, and the light emitting element 232 and the light receiving element 233 of each element combination 231 intersect in opposite directions. The optical signal output from the light emitting element 232 passes through the recycling component 12 and is received by the light receiving element 233 to detect the degree of contamination of the recycling component 12. The wall of the sleeve 215 is provided with a light transmitting through hole 216 corresponding to the light transmitting element 232 and the light receiving element 233, and the light signal output by the light transmitting element 232 is transmitted to the detecting tube 25 through the corresponding light transmitting through hole 216, and the light signal is transmitted to the light receiving element 233 through the corresponding light transmitting through hole 216 after passing through the detecting tube 25 and is received by the light receiving element 233.

In this embodiment, the detecting element 23 is divided into a first element group 231a and a second element group 231 b. Visible light is transmitted between the light emitting element 232 and the light receiving element 233 of one of the first element combination 231a and the second element combination 231b, and invisible light, such as infrared light, is transmitted between the light emitting element 232 and the light receiving element 233 of the other. In this embodiment, the first component assembly 231a and the second component assembly 231b cooperate to detect the dirt level of the dirt recovered by the recovery component 12, so as to further improve the accuracy of detecting the dirt level.

The sleeve 215 is provided with a pair of light-transmitting through holes 216 corresponding to the first component assembly 231a and the second component assembly 231 b. The light emitting elements 232 and the light receiving elements 233 of each element combination 231 are respectively accommodated in different light shielding cavities 221. In other words, the light emitting element 232 and the light receiving element 233 of the first element combination 231a and the light emitting element 232 and the light receiving element 233 of the second element combination 231b are respectively accommodated in different light shielding cavities 221. Fig. 6 exemplarily illustrates that the light shielding body 22 encloses four light shielding cavities 221, and the light emitting element 232 and the light receiving element 233 of the first element combination 231a and the light emitting element 232 and the light receiving element 233 of the second element combination 231b are respectively accommodated in the corresponding light shielding cavities 221. The optical path of the first component assembly 231a is independent of the optical path of the second component assembly 231 b.

In one embodiment, the light shielding body 22 includes a first light shielding portion 223 and a second light shielding portion 224. The first light shielding portion 223 encloses the light shielding cavity 221. The second light shielding portion 224 is connected to the first light shielding portion 223, and the first light shielding portion 223 and the second light shielding portion 224 are sequentially arranged along the circumferential direction of the sleeve 215. The second light shielding portion 224 is attached to the outer side wall of the sleeve 215, that is, the second light shielding portion 224 is in seamless butt joint with the outer side wall of the sleeve 215, so that optical signals can be prevented from passing between the second light shielding portion 224 and the sleeve 215, optical signal crosstalk is avoided as much as possible in the detection assembly 20, and detection accuracy of dirt is further improved.

For the above example in which the detection element 23 is divided into the first element combination 231a and the second element combination 231b, the light shielding body 22 includes four first light shielding portions 223, and each of the first light shielding portions 223 encloses one light shielding cavity 221. Correspondingly, the number of the second light shielding portions 224 is four, and each of the first light shielding portions 223 and each of the second light shielding portions 224 are alternately arranged one by one along the circumferential direction of the sleeve 215. Each second light shielding portion 224 is attached to an outer sidewall of the sleeve 215, so as to prevent the optical signal output by the optical emitting element 232 from being transmitted to the optical receiving element 233 along the outer periphery of the sleeve 215, and not passing through the detecting tube 25, so that the interference optical signal received by the optical receiving element 233 can be reduced, and the optical signal crosstalk generated in the detecting assembly 20 is avoided as much as possible, and the detection accuracy of the dirt degree is further improved.

In one embodiment, the detection assembly 20 further includes a circuit board 24. The circuit board 24 is accommodated in the accommodating cavity 211, and the circuit board 24 is electrically connected with the detecting element 23. The circuit board 24 is integrated with a control circuit, and the circuit board 24 is used for controlling the detecting element 23 to detect the dirt degree of the dirt recovered by the recovery assembly 12. Wherein the circuit board 24 is disposed around the outer circumference of the sleeve 215.

The light shielding body 22 further has an opening 222, and the opening 222 communicates with the light shielding cavity 221. The detecting element 23 is accommodated in the light shielding cavity 221 through the opening 222. The cap 214 is abutted with the base 213 in the third direction to form the accommodating chamber 211. During the process of docking the cap 214 with the base 213, the detecting element 23 moves toward the light shielding cavity 221 along the third direction, and the detecting element 23 is accommodated in the light shielding cavity 221 through the opening 222. The light shielding body 22 around the opening 222 of the present embodiment is attached to the circuit board 24, so that the light shielding cavity 221 forms a relatively closed cavity through the circuit board 24, and light in the external environment is prevented from entering the light shielding cavity 221, so that the light crosstalk between the light in the external environment and the light transmitted by the detecting element 23 is avoided as much as possible, and the detection accuracy of the dirt is improved.

It should be noted that, the light shielding cavity 221 forms a relatively closed cavity, and it should be understood that the light shielding cavity 221 is closed to some extent. The light blocking cavity 221 may be completely closed; alternatively, the light shielding cavity 221 is not completely closed, but the light transmittance of the light shielding cavity 221 is small enough to significantly affect the detection accuracy of the dirt level.

In an embodiment, the cap 214 and the sleeve 215 are attached to each other, i.e. the cap 214 and the sleeve 215 are in seamless joint, so that light in the external environment can be prevented from entering the light shielding cavity 221 between the cap 214 and the sleeve 215, and the light in the external environment and the light transmitted by the detecting element 23 are prevented from being in light-emitting condition as much as possible, so as to improve the detection accuracy of the dirt level. Specifically, the cap 214 overlaps the end of the sleeve 215 facing away from the base 213.

Optionally, the cap 214 and the light shielding body 22 may be integrally formed, i.e. the cap 214 also has a light shielding function, so that light in the external environment can be further prevented from entering the light shielding cavity 221 between the cap 214 and the sleeve 215, and the light in the external environment and the light transmitted by the detecting element 23 are prevented from being transmitted as much as possible, so as to improve the detection accuracy of the dirt level. The cap 214 and the light shielding body 22 may be made of a flexible material such as light shielding rubber. The light shielding body 22 is in interference fit with the sleeve 215, so that the second light shielding portion 224 is attached to the outer side wall of the sleeve 215. The cap 214 is interference fit with the sleeve 215 such that the cap 214 and sleeve 215 fit against each other. The cap 214 is interference fit with the base 213 to block light from the external environment from entering between the cap 214 and the base 213.

In one embodiment, the detecting assembly 20 further includes a carrying seat 26, and the detecting tube 25 and the base are disposed on the carrying seat 26. The detection tube 25 and the bearing seat 26 may be integrally formed. The carrier 26 has a fixing portion 261, and the carrier 26 is fixed to the base station body 11 by the fixing portion 261, so that the entire detection module 20 is fixed to the base station body 11.

In one embodiment, the detecting element 20 has a first direction (shown by arrow X in fig. 6, the same applies hereinafter) and a second direction (shown by arrow Y in fig. 6, the same applies hereinafter) perpendicular to each other. The light-transmitting through hole 216 is disposed opposite to the light-shielding cavity 221 along the first direction. Wherein the length L of the light shielding cavity 221 in the second direction is 5mm to 6mm, e.g. 5mm, 5.2mm, 5.4mm, 5.6mm, 5.8mm, 6mm, etc., as shown in fig. 6. In other words, the length of the light shielding cavity 221 in the second direction is set reasonably in this embodiment, so that the optical signal transmitted by the detecting element 23 is not too concentrated or too divergent, and the detection accuracy of the dirt level is further improved.

In one embodiment, the distance H between the detecting element 20 and the bottom surface of the base station body 11 is 180mm or more, as shown in fig. 2. Specifically, the distance between the bottom surface of the carrier 26 of the detection assembly 20 and the bottom surface of the base station main body 11 is 180mm or more. The bottom surface of the base station body 11 is the surface of the base station body 11 that contacts the ground when the base station 10 is properly placed. In this embodiment, the detection assembly 20 is disposed at a position far away from the ground, so that dirt can be prevented from accumulating on the detection assembly 20 as much as possible, and further the detection accuracy of the dirt degree is prevented from being affected due to accumulation of dirt.

The technical scheme provided by the embodiment of the utility model is explained below in connection with a specific application scene.

Application scenario one:

the cleaning device is a sweeper integrating sweeping and mopping functions. The cleaning device is used in conjunction with the base station 10. After the cleaning device returns to the base station 10, the base station 10 cleans the rag of the cleaning device by using clean water, the generated sewage is collected in the sewage collecting tank 111, and the sewage in the sewage collecting tank 111 is recovered to the sewage storage tank 122 through the recovery pipe 121. The sewage may pass through the sensing assembly 20 during the recovery process to sense the degree of contamination of the sewage by the sensing assembly 20. On the one hand, the dirty water reflects the dirty degree of the rag on the cleaning device, and the detection assembly 20 can judge whether the rag is cleaned or not by detecting the dirty degree of the dirty water, so that the cleaning times of the rag are controlled to be increased or decreased, and the cleaning of the rag is ensured; on the other hand, the sewage also reflects the dirt degree of the ground, and the detecting assembly 20 can determine whether the ground is clean by detecting the dirt degree of the sewage, so as to control the increase or decrease of the cleaning times of the ground, so as to ensure that the ground is clean.

The base station 10 can ensure the cleaning effect of the rag on the cleaning device and the cleaning effect of the floor by being provided with the detection assembly 20.
