The utility model discloses a water retaining member can avoid falling the water full detection component false alarm that causes on the water full detection component from the dirty soil that the manger plate chamber flowed, guarantees cleaning equipment normal work, effectively promotes user's use experience.

For ease of understanding, the specific structure of the cleaning apparatus of the present disclosure and its principle of operation will be described in detail below in connection with one embodiment with reference to fig. 1 to 9.

The present disclosure provides a cleaning apparatus for cleaning a work surface of a floor, carpet, or the like. The cleaning apparatus comprises at least a waste receptacle for storing dirt drawn from the work surface.

It will be appreciated that the cleaning apparatus may also include a body, a floor brush assembly and a fan assembly. Wherein the body serves as a carrier for mounting the various functional elements required for the cleaning device. The floor brush component is arranged at the bottom end of the machine body and is used for cleaning the working surface. The floor brush assembly comprises a floor brush shell, a rolling brush and a rolling brush cover. The floor brush shell is provided with a dirt sucking port, the rolling brush is rotatably connected to the floor brush shell, and the rolling brush is contacted with the working surface in the cleaning process of the cleaning equipment so as to clean the working surface.

The fan assembly is used for forming negative pressure in the sewage bucket, so that dirt on the working face is sucked into the inner cavity of the sewage bucket from the dirt suction port on the floor brush shell under the action of the negative pressure. The dirt can only comprise sewage or can be a mixture of sewage and solid garbage.

As shown in fig. 1 to 3, the slop tank includes a tank body 1, an end cover bracket 2, and a water full detection assembly 3. Wherein, a dirt inlet channel 12 communicated with the inner cavity 11 is arranged in the barrel body 1, so that dirt on the working surface can enter the inner cavity 11 from the dirt inlet channel 12.

A water blocking housing 21 having a water blocking chamber 22 is provided on the end cap holder 2, and the sewage outlet 121 of the sewage inlet passage 12 is configured to extend into the water blocking chamber 22 of the water blocking housing 21. As shown in fig. 2, in an embodiment of the present disclosure, an air outlet 23 is further provided on the end cover support 2, and the water blocking housing 21 is used for isolating the water blocking cavity 22 from the air outlet 23, so that when the dirt in the dirt inlet channel 12 flows out from the dirt outlet 121, the dirt can be blocked in the water blocking cavity 22 and cannot be directly sucked into the air outlet 23 by the fan assembly, thus, the dirt can be effectively prevented from being sucked into the fan assembly through the air outlet 23, and the fan assembly is prevented from being unable to work normally due to water inlet.

The water blocking housing 21 may be variously constructed. Specifically, as shown in fig. 4 and 5, in one embodiment of the present disclosure, the water blocking housing 21 includes a connecting wall 212 and enclosing side walls 211 located at opposite sides of the connecting wall 212, and the connecting wall 212 and the enclosing side walls 211 enclose a water blocking cavity 22 having an open end. Further, as shown in fig. 4 and 5, the water blocking cavity 22 is provided with an open end opposite to the connecting wall 212, that is, the open end is disposed on the opposite side of the water blocking housing 21 to the connecting wall 212, which may also be understood that the connecting wall 212 and the enclosing side wall 211 enclose a C-shaped or U-shaped structure with an open end. When the end cover bracket 2 is installed in the barrel body 1, the opening end of the water retaining shell 21 faces the inner wall of the barrel body 1, and the inner wall of the barrel body 1 can be covered on the opening end, so that the barrel body 1 and the water retaining shell 21 jointly enclose a square water retaining cavity 22; the tub 1 may be spaced apart from the open end by a predetermined distance, and may define a square water blocking cavity 22 with an opening formed in a side surface thereof together with the water blocking housing 21.

In other embodiments of the present disclosure, a sealing wall may be disposed on the other side opposite to the connecting wall 212, so that the connecting wall 212, the enclosing side wall 211 and the sealing wall together enclose the water blocking cavity 22, which is not limited herein.

The water full detection assembly 3 is used for triggering when the sewage bucket reaches a water full state, so that the floor brush assembly and the fan assembly are controlled to stop in time, sewage in the sewage bucket is prevented from overflowing, and a user is informed of timely pouring out the dirt in the sewage bucket.

As shown in fig. 3 and 5, the end cover bracket 2 is provided with a water blocking member 24 positioned at the side of the water blocking cavity 22, the water full detection assembly 3 is positioned at a position outside the water blocking member 24, the water blocking member 24 comprises a first water blocking portion 241 and a second water blocking portion 242, and the first water blocking portion 241 is configured to separate dirt and sewage flowing downwards from the bottom of the water blocking cavity 22 from the water full detection assembly 3; the second water blocking portion 242 has a space 245 between it and the side of the water blocking cavity 22 and is configured to separate the water full detection assembly 3 from the space 245.

It will be appreciated that the first water blocking portion 241 may separate the dirt flowing downwards from the bottom of the water blocking cavity 22 from the full water detection assembly 3, so as to avoid the dirt flowing downwards from the bottom of the water blocking cavity 22 falling onto the full water detection assembly 3; the second water blocking portion 242 and the side portion of the water blocking cavity 22 are provided with a space 245, and the second water blocking portion 242 can separate the full water detection assembly 3 from the space 245, so that when sewage in the water blocking cavity 22 flows downwards from the space 245, the second water blocking portion 242 can separate the dirty sewage flowing downwards from the space 245 from the full water detection assembly 3, and the dirty sewage flowing downwards from the space 245 is prevented from falling onto the full water detection assembly 3. The water baffle 24 can avoid false alarm of the water full detection assembly 3 caused by that a large amount of dirt falls onto the water full detection assembly 3 from the dirt flowing out of the water baffle cavity 22, ensure normal work of the cleaning equipment and effectively promote use experience of a user.

In one example, the first water blocking portion 241, the second water blocking portion 242, and the partition portion 243 are integrated on the water blocking member 24, the first water blocking portion 241 is formed by the surrounding sidewall 211 extending downward, and the second water blocking portion 242 and the partition portion 243 are formed at the side surface of the water blocking member 24. Of course, in other examples, the first water deflector 241, the second water deflector 242, the partition 243 may be independent of the water deflector 24.

As shown in fig. 2, in one embodiment of the present disclosure, the water fullness detecting assembly 3 and the air outlet 23 are located at both sides of the connection wall 212 in the thickness direction of the wastewater tank. Thus, after the dirt flows out from the water blocking cavity 22, the dirt can deflect to the side where the air outlet 23 is located under the action of air flow and then falls into the sewage bucket, so that the movement track of the dirt is far away from the full water detection assembly 3, and the dirt is further prevented from being stained on the full water detection assembly 3.

As shown in fig. 3, in one embodiment of the present disclosure, the water deflector assembly further includes a fixing portion 213 at the top of the water deflector 24, and the water fullness detecting assembly 3 is configured to extend downward from the fixing portion 213, with a gap between the water fullness detecting assembly 3 and the water deflector 24 below the fixing portion 213. By providing the fixing portion 213, the water full detection assembly 3 is facilitated to extend downward to the target position. And because the water full detection assembly 3 has a clearance with the water baffle 24, even if a part of sewage is attached to the water baffle 24, the sewage is difficult to be stained on the water full detection assembly 3, thereby further preventing false alarm of the water full detection assembly 3.

Further, as shown in fig. 3, in one embodiment of the present disclosure, the fixing portion 213 is configured to extend downward to a position not more than half of the height of the connection wall 212. In this way, the water full detection assembly 3 can be ensured to be exposed from the fixing part 213 for a long length, so that the top end of the water full detection assembly 3 can be kept at a certain distance from the bottom edge of the connecting wall 212, and dirt is prevented from being attached to the water full detection assembly 3 after flowing down from the bottom of the connecting wall 212 due to the fact that the water full detection assembly 3 is exposed from the fixing part 213 for too short.

The water-full detection assembly 3 may be an optical detection assembly, a resistance detection assembly, or any other remote water-full detection assembly. When the water full detection assembly 3 is a resistance detection assembly, in one embodiment of the present disclosure, as shown in fig. 3, the water full detection assembly 3 includes a first probe 31 and a second probe 32 disposed at both sides of the water blocking housing 21. During operation of the full water detection assembly 3, when the resistance between the measuring point 33 of the first probe 31 and the measuring point 33 of the second probe 32 is smaller than a preset value, both can be conducted, so that a full water signal of the sewage bucket is sent to the cleaning device. Specifically, as shown in fig. 3, in one embodiment of the present disclosure, the first probe 31 and the second probe 32 may include a connection section 34 and a measurement point 33, where the first probe 31 and the second probe 32 are integrally formed of conductive plastic, and the measurement point 33 is formed by adding a metal layer to the conductive plastic, and the connection section 34 is coated with an insulating layer, and the insulating layer is formed of a hydrophobic material, so that the adhesion degree of sewage may be reduced.

It will be appreciated that during normal operation of the cleaning assembly, dirt on the working surface is continually sucked into the interior cavity 11 of the waste basket; when the sewage bucket reaches the full state, the measuring point 33 of the first probe 31 and the measuring point 33 of the second probe 32 are soaked by sewage, and the first probe 31 and the second probe 32 can be conducted because the resistance of the sewage is far smaller than that of air, and the full detection assembly 3 sends a full signal of the sewage bucket to the cleaning equipment so as to remind a user to clean the sewage in the sewage bucket.

In the working process of the cleaning assembly, when a large amount of dirt falls from the water blocking cavity 22, the dirt may contact with the measuring points 33 of the first probe 31 and the second probe 32 at the same time, so that the first probe 31 and the second probe 32 are conducted in advance, and the water full detection assembly 3 is wrongly reported. At this time, the sewage tank has not reached a full state, and the user can pour out less dirt from the inside of the sewage tank.

When the sewage bucket is in a standing state and does not reach a full water state, part of dirt is attached to the end cover support 2, and the first probe 31 and the second probe 32 are just conducted when the part of dirt is carried out, the full water detection assembly 3 also sends a full water signal of the sewage bucket to the cleaning equipment, and false alarm is caused. And only after the user cleans the part of dirt, the water full detection assembly 3 can work normally, so that the workload of the user is increased, and the use experience of the user is also influenced.

Therefore, as shown in fig. 4 and 6, in one embodiment of the present disclosure, the water deflector 24 is configured to extend downwardly beyond the bottom edge of the connecting wall 212; the measuring points 33 of the first and

second probes

31, 32 are lower than the bottom edge of the connecting wall 212 and higher than the position of the bottom edge of the water deflector 24.

It will be appreciated that when the water full detection assembly 3 includes the first probe 31 and the second probe 32 disposed on two sides of the water blocking housing 21, the water blocking members 24 are correspondingly disposed on two sides of the water blocking cavity 22, and the first probe 31 and the second probe 32 are respectively disposed on the outer sides of the corresponding water blocking members 24, so that erroneous reporting of the water full detection assembly 3 caused by scattering of a large amount of dirt under the water blocking cavity 22 can be avoided by avoiding the dirt falling from the water blocking cavity 22 to the first probe 31 and the second probe 32.

Further, since the measuring points 33 of the first and

second probes

31 and 32 are located below the bottom edge of the water blocking housing 21 and above the bottom edge of the water blocking member 24. Like this, when the sewage bucket is in to rest, and does not reach full state of water, the dirty first probe 31 of messenger and second probe 32 of adhesion on the end cover support 2 is wanting to switch on, not only need walk around manger plate casing 21, still need pass through respectively by manger plate casing 21 downwardly extending to first probe 31, on the measuring point 33 of second probe 32, thereby the required wall climbing distance of dirty has been prolonged greatly, just also increased the degree of difficulty that the dirty switches on first probe 31 and second probe 32, the possibility that the dirty switches on first probe 31 and second probe 32 has been reduced, thereby avoid full detection component 3 to produce the false alarm, guarantee cleaning device normal work, thereby reduce user's work load, effectively promote user's use experience.

To further increase the wall climbing distance required for the dirt attached to the end cover bracket 2, as shown in fig. 7, in one embodiment of the present disclosure, the connection wall 212 is configured to protrude beyond the edge of the first water blocking portion 241 in the horizontal direction. Fig. 5 is a cross-sectional view of the sewage bucket of the present disclosure in a horizontal plane, referring to the view direction of fig. 5, such that the water blocking member 24 is located substantially in a vertical direction inside the bucket body 1 and the connection wall 212 protrudes rearward in a horizontal direction from an edge of the first water blocking portion 241 when the end cap holder 2 is mounted inside the bucket body 1.

Thus, when the sewage tank is at rest and the state of full water is not reached, the dirt attached to the end cover bracket 2 is intended to pass through the first probe 31 and the second probe 32, and not only pass through the measuring points 33 extending downward from the water blocking housing 21 to the first probe 31 and the second probe 32, respectively, but also need to bypass the connecting walls 212 protruding from the edges of the two first water blocking portions 241 on the water blocking housing 21. It can be seen that, by making the connecting wall 212 protrude from the edge of the first water blocking portion 241, the wall climbing distance required by the dirt is further prolonged, so that the difficulty of conducting the first probe 31 and the second probe 32 by the dirt is further increased, and the possibility of conducting the first probe 31 and the second probe 32 by the dirt is further reduced, and the possibility of false alarm of the full water detection assembly 3 is also reduced.

To further avoid false positives of the water full detection assembly 3 caused by the scattering of a large amount of dirt under the water blocking cavity 22, as shown in fig. 8 and 9, in one embodiment of the present disclosure, the portion of the water blocking member 24 below the bottom edge of the connecting wall 212 is configured to extend obliquely inward. In this way, the water guard 24 can guide the dirt falling from the water guard cavity 22 to fall from the central position of the water guard housing 21, thereby further avoiding false alarm of the water full detection assembly 3 caused by scattering of a large amount of dirt below the water guard cavity 22.

In order to prevent large solid waste in dirt from entering the inner cavity 11 and adhering to the outer wall of the water blocking housing 21, causing the water full detection assembly 3 to be erroneously turned on, and also to facilitate cleaning of the solid waste, as shown in fig. 4, in one embodiment of the present disclosure, the water blocking housing 21 includes a solid-liquid separation frame 25, and a portion of a side wall of the solid-liquid separation frame 25 is configured to cooperate with the first water blocking portion 241; the second water blocking portion 242 is configured to extend from the first water blocking portion 241 to have a space 245 from the side wall of the solid-liquid separation frame 25; dirt flowing from the side walls of the solid-liquid separation frame 25 is configured to flow downwardly through the gap 245.

It can be seen that the solid-liquid separation frame 25 can be mounted on the enclosing side wall 211 or the connecting wall 212 through the opening end, and the space enclosed by the solid-liquid separation frame 25 is the water blocking cavity 22; the dirt flowing out of the dirt inlet passage 12 is configured to flow into the tub 1 through the solid-liquid separation frame 25.

By providing the solid-liquid separation frame 25 in the water blocking cavity 22, after the dirt mixed with the solid waste flows into the water blocking cavity 22 from the dirt outlet 121 of the dirt inlet channel 12, the solid waste with larger particles can be blocked in the solid-liquid separation frame 25 by the solid-liquid separation frame 25, and the residual dirt flows into the barrel body 1 through the solid-liquid separation frame 25. In this way, the large solid garbage in the dirt can be prevented from entering the inner cavity 11, and then the large solid garbage is prevented from adhering to the outer wall of the water retaining shell 21 to guide the dirt to conduct the first probe 31 and the second probe 32. And when the user cleans the garbage in the sewage bucket, the user is also convenient to treat the solid garbage with larger particles and the residual dirt respectively, so that the workload of the user is reduced.

Specifically, as shown in fig. 4, in one embodiment of the present disclosure, the solid-liquid separation frame 25 includes a peripheral wall and a bottom wall that are shape-fitted to the water blocking chamber 22, and the peripheral wall is shape-fitted to the water blocking chamber 22 in a C or U shape, so that the solid-liquid separation frame 25 also has an opening at one side of the open end of the water blocking chamber 22, so that solid garbage can be cleaned from the opening. Moreover, in one embodiment of the present disclosure, the solid-liquid separation frame 25 is detachably disposed in the water blocking chamber 22. Specifically, the solid-liquid separation frame 25 may have a deformability, and the solid-liquid separation frame 25 is mounted on the inner wall of the water blocking chamber 22 by means of deformation of the peripheral wall thereof. After the solid-liquid separation frame 25 is installed in the water blocking cavity 22, the partial areas on two opposite sides of the peripheral wall of the solid-liquid separation frame 25 are exposed out of the enclosing side wall 211, so that when a user needs to clean the solid dirt or clean the solid-liquid separation frame 25, the end cover bracket 2 can be removed from the barrel body 1, and then the exposed part of the solid-liquid separation frame 25 from the enclosing side wall 211 is held, so that the whole solid-liquid separation frame 25 is taken out from the water blocking cavity 22.

In one embodiment of the present disclosure, as shown in fig. 4, a drain hole 252 is formed in a bottom wall of the solid-liquid separation frame 25, and a portion of the dirt flowing out of the dirt inlet channel 12 is configured to flow downward into the tub 1 through the drain hole 252. Similarly, as shown in fig. 4, in one embodiment of the present disclosure, the liquid outlet holes 251 are provided on both side walls of the peripheral wall of the solid-liquid separation frame 25, and a space 245 is provided between the second water blocking portion 242 and the liquid outlet holes 251 on the side wall of the solid-liquid separation frame 25; dirt flowing out of the liquid outlet aperture 251 is configured to flow downwardly through the gap 245. Thus, after the dirt flows into the water blocking chamber 22 from the dirt outlet 121 of the dirt inlet channel 12, part of the dirt can flow into the inner chamber 11 below after flowing out from the liquid outlet 251 on the side wall of the solid-liquid separation frame 25.

The particle size of the solid waste blocked in the solid-liquid separation frame 25 can be adjusted by adjusting the pore sizes of the liquid outlet 251 and the liquid outlet 252. The apertures of the liquid outlet holes 251 and the liquid outlet holes 252 are set to be of proper sizes, so that dirt can be ensured to smoothly flow out of the solid-liquid separation frame 25, and solid garbage in the dirt can be blocked in the solid-liquid separation frame 25 as much as possible.

As shown in fig. 4, in another embodiment of the present disclosure, the second water blocking portions 242 are configured to extend from the first water blocking portion 241 toward the opening direction of the water blocking cavity 22, and the distance between the two second water blocking portions 242 is greater than the distance between the two first water blocking portions 241. In this way, it is possible to facilitate the second water blocking portion 242 to be formed with the space 245 from the side wall of the solid-liquid separation frame 25.

Further, as shown in fig. 5, the second water blocking portion 242 is configured to extend in a direction toward the sidewall of the tub 1 to be in clearance fit or contact fit with the sidewall of the tub 1. Thus, during operation of the cleaning apparatus of the present disclosure, air cannot substantially flow from the side of the second water blocking portion 242 to the air outlet 23, but can only flow around from the bottom of the water blocking housing 21 to the air outlet 23, and thus the dirt is not driven to bypass the water blocking member 24 to reach the vicinity of the full water detection assembly 3, so that the dirt can be prevented from adhering to the full water detection assembly 3.

Further, as shown in fig. 3 and 5, in one embodiment of the present disclosure, a partition portion 243 extending toward the sidewall of the tub 1 is provided on the water blocking member 24, the partition portion 243 is configured to form an angle with the first water blocking portion 241 and the second water blocking portion 242, and is configured to extend to be in clearance fit or contact fit with the sidewall of the tub 1, and an open space is provided between the partition portion 243 and the first water blocking portion 241.

By providing the partition 243, the dirt is further prevented from flowing directly from the side surface side of the water blocking housing 21 to the air outlet 23, thereby further avoiding the air from driving the dirt to bypass the water blocking member 24 to reach the vicinity of the water full detection assembly 3, and preventing false alarm of the water full detection assembly 3. Moreover, because the space between the partition portion 243 and the first water blocking portion 241 is open, the air near the water full detection assembly 3 can normally flow, and the situation that the water full detection assembly 3 does not report or report later after the sewage bucket reaches the water full state because the air cannot normally flow is avoided.

As shown in fig. 3 and 5, in one embodiment of the present disclosure, the partition 243 is configured to extend outwardly from a position where the first water blocking portion 241 and the second water blocking portion 242 are connected, and the first probe 31 and the second probe 32 are configured to be positioned in the partition groove 244 formed by the first water blocking portion 241 and the partition 243. Since the first and

second probes

31 and 32 are positioned in the partition groove 244 formed by the first water blocking portion 241 and the partition portion 243, the partition groove 244 can protect the first and

second probes

31 and 32, and thus sewage can be prevented from flowing out of the water blocking chamber 22 and then flowing near the first and

second probes

31 and 32 as much as possible.

As shown in fig. 5, in one embodiment of the present disclosure, the partition portion 243 is configured to be approximately perpendicular to the first water blocking portion 241, the second water blocking portion 242, and the partition portion 243, the first water blocking portion 241, the second water blocking portion 242 are configured to be integrally formed with the water blocking housing 21. Since the partition portion 243 is configured to be approximately perpendicular to the first water blocking portion 241 and the second water blocking portion 242, the space in the partition groove 244 can be made large enough, and the probability of dirt accumulating in the partition groove 244 can be reduced; even if dirt is accumulated, the user can conveniently clean the partition groove 244, and the whole partition groove 244 can be further ensured to be in an open state, so that the air near the first probe 31 and the second probe 32 can normally flow.

Further, since the partition portion 243, the first water blocking portion 241, and the second water blocking portion 242 are integrally formed with the water blocking housing 21, the connection structure between the partition portion 243, the first water blocking portion 241, and the second water blocking portion 242, and the water blocking housing 21 can be omitted, the connection strength between the partition portion 243, the first water blocking portion 241, and the second water blocking portion 242, and the water blocking housing 21 can be enhanced, and the number of processing steps required for the end cap bracket 2 can be reduced.

Further, as shown in fig. 3 and 5, in one embodiment of the present disclosure, the spacing 245 between the first probe 31, the second probe 32 and the corresponding separation groove 244 is not less than 2mm. Thus, even if a part of the sewage adheres to the inside of the isolation groove 244, the sewage drops cannot directly communicate with the measurement points 33 of the first and

second probes

31 and 32, and erroneous conduction of the first and

second probes

31 and 32 is further prevented.

It will be appreciated that in one embodiment of the present disclosure, the cleaning apparatus is configured to be inclined relative to the working surface in operation; the first and

second probes

31 and 32 are configured to be positioned above the partition groove 244 when the cleaning apparatus is in an operating state. Taking the direction of fig. 2 as an example, when the cleaning device works, because the first probe 31 and the second probe 32 are located above the isolation groove 244, part of dirt can flow into the inner cavity 11 from the inclined barrel body 1 located at one side of the inclined lower part of the first probe 31 and the second probe 32, so that the dirt and the barrel body 1 are prevented from impacting as much as possible, and false alarm of the water full detection assembly 3 caused by scattering of a large amount of dirt below the water blocking cavity 22 is avoided. And the air outlet can be positioned above the water blocking cavity 22, so that dirt is prevented from being sucked into the air outlet 23 by the fan assembly, and water inflow of the fan assembly is avoided.

The present disclosure also provides a solution tank, the solution tank comprising:

the barrel body 1 is internally provided with a liquid inlet channel;

the end cover bracket 2, the end cover bracket 2 is provided with a water blocking shell 21 with a water blocking cavity 22, and a sewage outlet 121 of the liquid inlet channel is configured to extend into the water blocking cavity 22 of the water blocking shell 21;

A water full detection assembly 3;

wherein, the end cover bracket 2 is provided with a water baffle 24 positioned at the side part of the water baffle cavity 22, the water full detection assembly 3 is arranged at the position outside the water baffle 24, the water baffle 24 comprises a first water baffle 241 and a second water baffle 242, and the first water baffle 241 is configured to separate dirt flowing downwards from the bottom of the water baffle cavity 22 from the water full detection assembly 3; the second water blocking portion 242 has a space 245 between it and the side of the water blocking cavity 22 and is configured to separate the water full detection assembly 3 from the space 245.

The solution tank can effectively avoid false alarm generated by the water full detection component 3, can be the sewage tank, and can be used for storing other liquids, and the specific structure and principle are referred to above and are not repeated here.

In one embodiment of the present disclosure, there is also provided a control method of a cleaning apparatus, implemented by the cleaning apparatus described above, including the steps of: and when the water full detection component is conducted, the equivalent resistance is smaller than a first threshold value, and after the water full detection component is continuously conducted for a first preset time, a water full signal is sent out.

In the embodiment of the water full detection assembly 3 of the present disclosure comprising the first probe 31, the second probe 32, it is determined whether the current sewage tank reaches the water full state based on whether the equivalent resistance between the two probes reaches the threshold value, and the duration of conduction.

In one embodiment of the disclosure, for example, when the sewage in the sewage bucket reaches the measuring point of the two probes, the two probes are conducted, the equivalent resistance between the two probes is judged to be smaller than a first threshold value in the detection loop, and the first preset time is continuously conducted, the current sewage bucket is considered to be in a water full state, and thus a water full signal is sent out.

In one embodiment of the disclosure, if the equivalent resistance between the two probes is determined to be greater than the first threshold and less than the second threshold in the detection loop and is continuously conducted for a second preset time, the current sewage bucket is considered to be in a water full state. This is because the environment in the sewage bucket is complicated, and foam is generated on the surface of sewage in the process that sewage falls from the water blocking chamber. In addition, when a user holds the cleaning apparatus in his/her hand during cleaning, the contaminated water may shake in the contaminated water tank and generate foam on the surface of the contaminated water. A large amount of foam generated in the slough tank may overflow from the slough tank, and thus the slough tank should be considered to be in a full state at present when both probes detect the foam.

That is, the present disclosure detects whether the foam on the surface of the contaminated water reaches a predetermined height with the contaminated water through two probes. Because the foam is mixed with air and sewage, when the foam reaches the measuring point of the two probes, the equivalent circuit of the two probes after being conducted is larger than the equivalent circuit of the sewage when being conducted, based on the equivalent circuit, when the equivalent resistance between the two probes is judged to be larger than a first threshold value and smaller than a second threshold value in the detection loop, and the foam is continuously conducted for a second preset time, the current state can be considered to be in a foam conducting state.

The first and second thresholds of the present disclosure may be dependent on the particular sewage and foam conditions. In a specific embodiment of the present disclosure, the first threshold may be 250 kiloohms and the second threshold may be 350 kiloohms, depending on the implementation of the specific detection loop. In this embodiment, the second threshold value may be set to 1.1 to 1.5 times the first threshold value according to the characteristics of the foam. The first threshold value and the second threshold value may be numerical ranges, and are not described in detail herein.

In addition, the second preset time of the present disclosure may be longer than the first preset time, because the condition of foam conduction is more complex than the condition of the sewage channel, so that the condition of false triggering can be ensured by selecting the second preset time for judging foam conduction to be longer than the first preset time for judging sewage euro-ventilation. For example, in one embodiment of the present disclosure, the first predetermined time may be 1.5s, and the second predetermined time may be 5s, which may be specifically selected according to actual needs, and in this embodiment, the second predetermined time is 3 times or more of the first predetermined time for accuracy of judgment according to the characteristics of the foam. The first predetermined time and the second predetermined time may be numerical ranges, and are not specifically described herein.

In other embodiments, the water-full condition in a plurality of different scenarios may also be determined based on a combination of equivalent resistance and duration between two probes, as described above by way of example only with respect to foam scenarios and liquid scenarios.
