Preferred embodiments of the present utility model are described in detail below, however, the present utility model may have other embodiments in addition to these detailed descriptions.

A base station 100 according to an embodiment of the present utility model is described below with reference to fig. 1 to 4. As shown in fig. 1 to 4, the base station 100 includes: a base station main body 110 including a power supply plug; the sewage tank body 120 is arranged on the base station body 110, the sewage tank body 120 comprises a sewage tank 140 and a first power piece 150, and the first power piece 150 is connected with the sewage tank 140 and is used for discharging sewage in the sewage tank 140; wherein, the sewage tank main body 120 is provided with a power supply port 131 electrically connected with the first power member 150; when the sewage tank main body 120 is assembled in place on the base station main body 110, the power supply plug is inserted into the power supply port 131 to supply power to the first power member 150.

The first power member 150 may be a liquid delivery device such as a sewage pump, and is not limited thereto.

The assembly of the base station body 110 and the sewage tank body 120 in place may mean that the degree of assembly between the base station body 110 and the sewage tank body 120 is within a preset assembly range. When the assembly degree between the base station main body 110 and the sewage tank main body 120 is within the preset assembly range, the base station main body 110 and the sewage tank main body 120 are assembled in place, and at this time, the power supply plug on the base station main body 110 can be inserted into the power supply port 131, so that the first power member 150 can be powered, and the first power member 150 can work normally to discharge sewage in the sewage tank 140; when the assembly degree between the base station main body 110 and the sewage tank main body 120 is not within the preset assembly range, the base station main body 110 and the sewage tank main body 120 cannot be assembled in place, and at this time, the power supply plug on the base station main body 110 cannot be correctly inserted into the power supply port 131, so that the first power component 150 cannot be normally powered, and the first power component 150 cannot be normally operated. Thus, the present utility model provides a base station 100 in which the power supply plug can be inserted into the power supply port 131 to normally supply power to the first power member 150 when the sewage tank main body 120 and the base station main body 110 are assembled in place, so that the first power member 150 can normally operate.

According to the base station 100 of the present utility model, when the base station main body 110 and the sewage tank main body 120 are assembled in place, the power supply plug on the base station main body 110 can be inserted into the power supply port 131 on the sewage tank main body 120, so that the first power member 150 can be powered, the first power member 150 can be operated normally, and sewage in the sewage tank 140 can be discharged effectively.

It is understood that the base station 100 of the present utility model may be used with a cleaning robot having a mopping module, such as a floor mopping robot, a sweeping and mopping robot, etc. Taking the example that the base station 100 is applied to the sweeping and mopping robot, after the sweeping and mopping robot moves to the base station 100, cleaning operation can be performed on the mopping module of the sweeping and mopping robot in the cleaning tank of the base station 100, and sewage generated by cleaning is collected and stored through the sewage tank 140 in the base station 100, and is further discharged through the first power member 150.

In one embodiment of the present utility model, as shown in fig. 1, the sewage tank main body 120 includes a housing 130, the sewage tank 140 and the first power member 150 are disposed in the housing 130, and a power supply port 131 is disposed on the housing 130. The sewage tank 140 and the first power member 150 may be vertically disposed in the housing 150, or may be disposed in other configurations, which is not limited thereto.

In one embodiment of the present utility model, as shown in fig. 1, a relief hole 111 is provided in the base station main body 110, and when the sewage tank main body 120 is assembled in place on the base station main body 110, the location of the relief hole 111 corresponds to the location of the power supply port 131, and the power supply plug is used to insert the power supply port 131 through the relief hole 111.

It can be appreciated that when the sewage tank main body 120 and the base station main body 110 are not assembled in place, the power supply port 131 and the avoidance hole 111 are in a dislocation state, and the base station main body 110 can form complete or partial shielding for the power supply port 131, so that the power supply plug cannot be inserted into the power supply port 131, and the first power member 150 cannot work normally due to abnormal power supply.

When the sewage tank main body 120 and the base station main body 110 are assembled in place, the position of the avoidance hole 111 corresponds to the position of the power supply hole 131, and the power supply hole 131 can be exposed from the avoidance hole 111, so that the power supply plug can be inserted into the power supply hole 131 through the avoidance hole 111, the power supply of the first power piece 150 is normal, and the first power piece can work normally to discharge sewage in the sewage tank 140 outwards.

In one embodiment of the present utility model, as shown in fig. 2, the sewage tank 140 is provided with a liquid inlet 141, and the sewage tank body 120 further includes a filter member 161, and the filter member 161 is detachably connected to the sewage tank 140 for filtering sewage entering the sewage tank 140 through the liquid inlet 141.

In one example, after the cleaning robot moves to the base station 100, sewage generated by the floor mopping module of the cleaning robot is washed to enter the sewage tank 140 through the liquid inlet 141, and the sewage entering the sewage tank 140 is filtered by the filter 161 to remove large particle impurities in the sewage. The filter 161 may be a filter screen, a filter plate, or the like, and is not limited thereto.

Generally, since the filter 161 is detachably connected to the sump 140, the filter 161 is a replaceable component, and thus, in order for the base station 100 to function properly, it is necessary to secure the filter 161 in place with the sump 140 in addition to securing the sump body 120 in place with the base station body 110. When the filter 161 is in place, the base station 100 can operate normally; when the filter 161 is not installed in place, the base station 100 is in a non-working state, so as to avoid that the filter screen is not installed in place or cannot effectively perform the filtering effect.

It is understood that the assembly of the filter 161 with the sump 140 in place may mean that the degree of assembly between the filter 161 and the sump 140 is within a preset assembly range. When the assembly degree between the filter 161 and the sewage tank 140 is within the preset assembly range, the sensing member can sense the magnetic member 162 at this time, and the data processor can determine that the filter 161 and the sewage tank 140 are assembled in place according to the sensing data sent by the magnetic member 162, so that the base station 100 can work normally; when the assembly degree between the filter 161 and the sewage tank 140 is not within the preset assembly range, the sensing element cannot sense the magnetic element 162 or the magnetic field strength of the magnetic element 162 sensed by the sensing element is lower than the set value, the data processor can judge that the filter 161 and the sewage tank 140 are not assembled in place according to the sensing data sent by the magnetic element 162, and then the base station 100 can be controlled to be in a non-working state.

The magnetic member 162 may be selected from a magnetic material such as a magnet, the sensing member may be selected from a magnet position sensor, etc., the data processor may be selected from a central processing unit (Central Processing Unit, CPU), a data processing unit (Data Processing Unit, DPU), a digital signal processor (Digital Signal Processor, DSP), etc., and the sensing member and the data processor may be connected by a wired communication connection, a wireless communication connection, etc., which is not limited thereto.

The embodiment can prompt the user in time when the filter 161 is not installed or is not installed in place by arranging the prompt module, so that the user installs the filter 161 in place in time.

In one example, the alert module may be an audio alert module, a light alert module, or the like, which is not limited. Taking the reminding module as a light reminding module as an example, when the filter 161 is not assembled in place, the data processor sends a reminding instruction, and after receiving the reminding instruction, the light reminding module can send out light information for reminding a user that the filter 161 is not assembled in place.
