In order to prevent the sewage in the sewage tank 1 from overflowing excessively, the sewage collecting apparatus further includes an anti-overflow water detecting assembly that can be triggered when the water level in the sewage tank 1 reaches a preset water level, so that the cleaning device triggers an anti-overflow measure, such as stopping water suction and alarming.

The anti-overflow water detection assembly can be triggered in time by detecting the water level in the sewage tank 1 so that the cleaning device starts an epidemic prevention measure. However, when the cleaning device is used, the water level in the sewage tank 1 is inclined due to the temporary inclination, so that the problem of water level misdetection is easily caused.

In order to solve the above problems, as shown in fig. 11 and 12, the water flood prevention detection assembly includes a first electrode 61 and a second electrode 62, the top end of the first electrode 61 is connected to the top end of the second electrode 62, the bottom end of the first electrode 61 and the bottom end of the second electrode 62 both extend into the filter basket 4, and the water flood prevention detection assembly can be triggered after the first electrode 61 and the second electrode 62 are conducted for a preset time. The anti-overflow water detection assembly with the structure can be triggered after the first electrode 61 and the second electrode 62 are conducted for the preset time, and can not be triggered when the inclination time of the cleaning equipment is less than the preset time, so that the condition that the water level in the sewage tank 1 is inclined due to user operation is eliminated, and the condition of false triggering is reduced.

For the anti-overflow water detection component of easy to assemble, the bottom surface downwardly extending of apron 21 has two installation pipes 23, has seted up inlet 231 on the installation pipe 23, and first electrode 61 and second electrode 62 set up respectively in two installation pipes 23, and first electrode 61 and second electrode 62 contact with sewage through corresponding inlet 231. By providing the mounting pipe 23, the first electrode 61 and the second electrode 62 can be prevented from being conducted by splashing of the sewage in the sewage tank 1.

In this embodiment, the top end of the first electrode 61 extends out of the cover plate 21 and is connected with a first conductive member through a wire, the top end of the second electrode 62 extends out of the cover plate 21 and is connected with a second conductive member through a wire, and the first conductive member and the second conductive member are used for being connected with a controller of the cleaning device to form a detection loop. When the first electrode 61 and the second electrode 62 are conducted, the controller will detect the information in the detection loop to determine whether there is a risk of overflowing sewage. The information in the detection loop may be current, resistance, inductance, and capacitance change.

Further, the pitch of the first electrode 61 and the second electrode 62 is defined to be not less than 30mm; it can be understood that the first electrode 61 and the second electrode 62 each have a central axis with a spacing M that is not less than 30mm. Based on the restriction on the distance between the two electrodes, the conductor is limited to reach more than 30mm to be able to contact the first electrode 61 and the second electrode 62 simultaneously, and a closed-loop path with interference property is further avoided. However, when the distance between the first electrode 61 and the second electrode 62 is too large, undesirable phenomena such as: when water contacts the first electrode 61 and the second electrode 62 at the same time, the distance between the electrodes is too large, which results in too large resistance of the water for conducting current, and thus the risk of current weakening or even interruption of the electric path occurs; thus, the present application further defines that the spacing of the first electrode 61 and the second electrode 62 is no greater than 150mm.

In this embodiment, the inlet 231 sets up in the bottom of erection column 23, and the bottom and the lateral part of inlet 231 all are provided with the opening, so, along with the increase of water level, water liquid can be followed bottom contact electrode to can play better fender effect at its lateral part.

In some embodiments, the catchment 231 may also be provided at the side of the mounting post 23.

Further, the length P of the first electrode 61 and the second electrode 62 extending into the corresponding water diversion port 231 is not less than 3mm. It can be understood that the first electrode 61 and the second electrode 62 have limited areas on the bottom surfaces, and are easily adhered to the attachments under the action of sewage, and if only the bottom surfaces of the first electrode 61 and the second electrode 62 are contacted with water, the detection is easily misaligned; therefore, the aforementioned limited length P of not less than 3mm is a length of not less than 3mm that the electrode can contact with the water liquid, so that the accuracy of water level detection can be ensured. In this embodiment, the length P of the electrode extending into the water inlet 231 is 4mm.

Based on the above arrangement, a gap for allowing water to flow is necessarily left between the electrode and the inner wall of the installation tube 23; when the gap is small, foreign matters are easy to insert and inconvenient for a user to clean, so that the minimum distance between the first electrode 61 and the second electrode 62 and the corresponding inner wall of the installation pipe 23 is not less than 2mm.

Further, the first electrode 61 and the second electrode 62 are all located in the mounting tube 23, the distance between the bottom end of the first electrode 61 and the bottom end of the mounting tube 23 is not less than 3mm, and the distance between the bottom end of the second electrode 62 and the bottom end of the mounting tube 23 is not less than 3mm, so that even if the conductor with a large length touches the lower end of the mounting tube 23, a certain distance is left from the contact with the electrodes. In this embodiment, the distance between the bottom ends of the two electrodes and the bottom end of the mounting tube 23 is 7mm.
