Example 1:

The filtering device in the existing base station is usually easily blocked by the dirt accumulated by filtering sewage, so that the base station can no longer perform sewage treatment, that is, it cannot continue to clean for the cleaning robot. In order to solve this technical problem, an embodiment of the present application provides a new base station. The new base station includes a filter screen, an electronically controlled valve, and a first fan. When the electronically controlled valve is opened, the first fan can blow the filter net. The garbage is sucked out, thus avoiding the accumulation of garbage on the filter screen.

The base station provided by the embodiments of the present application will be described below with reference to the accompanying drawings.

1 and 2 respectively show a schematic structural diagram of a base station provided by an embodiment of the present application. The base station is adapted to a cleaning robot. In FIGS. 1 and 2 , the base station includes: a filter screen 1, an electronically controlled valve 2. The first fan 3, the clean water tank 4, the sewage tank 5, the cleaning tray 6, the first water pump 7 and the second water pump 8, it should be pointed out that in FIG. 2, the electronic control valve 2 is closed. In FIGS. 1 and 2 , from the clean water tank 4 to the first water pump 7 , from the first water pump 7 to the cleaning tray 6 , from the cleaning tray 6 to the first fan 3 , and from the first fan 3 to the sewage tank 5 , each of The lines with arrows indicate the pipes that can realize water circulation, and the lines with arrows from the first fan 3 to the sewage tank 5 indicate that the corresponding pipes are embedded in the sewage tank 5, and the pipes also serve as the water inlet of the sewage tank 5. . It can be seen from Figures 1 and 2 that the first fan 3 is outside the sewage tank 5, the filter screen 1 is in the sewage tank 5 and is close to the upper part of the sewage tank 5, when the electronically controlled valve 2 is closed, the sewage tank 5 is A closed sewage tank 5, when the electronically controlled valve 2 is opened, the sewage tank 5 communicates with the outside of the sewage tank 5 through the opened electronically controlled valve 2. It should be pointed out that the position of the electronically controlled valve 2 in the sewage tank 5 is higher than the position of the filter screen 1 in the sewage tank 5, and the position of the first fan 3 is also higher than the position of the electronically controlled valve 2, so that the subsequent The waste on the water inlet of the sewage tank 5 and/or the filter screen 1 is sucked out by the first fan 3 .

The working principle of the base station is as follows:

When the base station needs to clean the cleaning robot, close the electronically controlled valve 2 on the sewage tank 5 . After that, the first water pump 7 extracts the water in the clean water tank 4 (to distinguish it from the water in the sewage tank 5, the water in the clean water tank 4 is subsequently referred to as clean water, and the water in the sewage tank 5 is referred to as sewage) to the cleaning tray 6. The mop of the cleaning robot (or mopping machine) on 6 is cleaned. After the cleaning is completed, the clean water in the cleaning tray 6 will become sewage. At this time, the first fan 3 will suck the sewage in the cleaning tray 6 into the sewage tank 5. After the sewage is filtered through the filter screen 1 arranged above the sewage tank 5 , it enters the sewage tank 5 . Since the filter screen 1 has a filtering function, the garbage in the sewage will be filtered out and remain on the filter screen 1 . Since when the electronically controlled valve 2 is closed and there is too much garbage on the filter screen 1, the area formed by the filter screen 1 and the electronically controlled valve 2 in the sewage tank 5 is a closed area, so the rotational speed of the first fan 3 will change. Fast, at this time, the current of the first fan 3 will also increase. That is, when the current of the first fan 3 is greater than the preset current threshold, it is determined that there is too much garbage on the filter screen 1 . When it is judged that there is too much garbage on the filter screen 1, the electronic control valve 2 is opened, and the air flow driven by the activated first fan 3 will suck out the water inlet of the sewage tank 5 and/or the garbage on the filter screen 1, and the sucked garbage passes through The open electronically controlled valve 2 comes out of the waste water tank 5 . When it is judged that there is not a lot of garbage on the filter screen 1, the electronic control valve 2 is not opened, and the base station sucks the filtered sewage from the sewage tank 5 into the clean water tank 4 through the second water pump 8, so as to realize the water circulation of the base station and the garbage disposal. Self-cleaning.

In the embodiment of the present application, since the base station includes the electronically controlled valve 2 and the first fan 3, and when the current of the first fan 3 is greater than the preset current threshold (that is, the filter screen 1 has too much garbage), the electronically controlled valve is opened. 2. Therefore, the garbage on the filter screen 1 on the sewage tank 5 can be sucked out by the rotating first fan 3, that is, when the garbage on the filter screen 1 is too much, the garbage on the filter screen 1 will be automatically cleaned, Thereby, the filter screen 1 is prevented from being blocked.

FIG. 3 shows a schematic structural diagram of another base station provided by an embodiment of the present application. In FIG. 3 , the base station further includes a second fan 9 . When the electronically controlled valve 2 is opened, the second fan 9 is activated, and the activated second fan 3 together with the first fan 3 drives the airflow to suck out the garbage on the filter screen 1 . Since the number of fans is increased, the speed of sucking out the garbage can be increased.

In some embodiments, in order to prevent the two fans from reducing the speed of gas flow due to different directions, the direction of the second fan is set to be the same as the direction of the first fan 3 . Since the directions of the two fans are the same, the direction of the flow speed of the gas driven by the two fans is also the same, so that the speed of sucking the garbage out of the filter screen 1 can be accelerated.

FIG. 4 shows a schematic structural diagram of another base station provided by an embodiment of the present application. In FIG. 4 , the base station further includes a garbage box 10 , and the garbage box 10 is used to store the water inlet and/or the filter screen from the sewage tank 5 1 suck out the garbage. As shown in FIG. 4 , in order to avoid omission of stored and sucked garbage, the garbage box 10 is provided to be tightly connected with the channel corresponding to the electronically controlled valve 2 , such as through a snap connection. Since the garbage box 10 stores garbage sucked out from the water inlet of the sewage tank 5 and/or the filter screen 1 , and the garbage contains less moisture, the garbage box 10 may also be called a dry garbage box 10 .

In some embodiments, a ventilation channel is provided at a position of the trash box 10 corresponding to the second fan. Since the dust box 10 is provided with a ventilation channel at the position corresponding to the second fan, when the second fan rotates, it will speed up the flow of the gas in the dust box 10, so that the speed of sucking the waste from the filter screen 1 can be accelerated.

In some embodiments, as shown in FIG. 5 , the second fan is arranged to correspond to the bottom of the trash box 10 . At this time, the bottom of the trash box 10 is provided with a ventilation channel. For example, the bottom of the trash box 10 is provided with a ventilation filter. , the ventilating filter is shown in the dotted line at the bottom of the garbage box 10 in FIG. 5 . Since the position of the second fan at the base station and the position of the first fan 3 at the base station are in an upper and lower position, the speed of the gas flow driven by the rotation of the upper and lower fans will be greater than the rotation of the two fans with the same height. The speed of the driven gas flow, therefore, through the above arrangement, the speed of the gas flow can be increased, thereby increasing the speed of sucking out the garbage.

In some embodiments, the bottom of the clean water tank 4 and/or the bottom of the sewage tank 5 further includes filter cotton 11 . 5 only shows a schematic diagram of the filter cotton at the bottom of the clean water tank 4 and/or the bottom of the sewage tank 5. In actual situations, the filter cotton may also be at the bottom of the clean water tank 4 and/or the sewage tank. Other positions at the bottom of 5 are not limited here.

Since the filter cotton can further filter the water, by arranging the filter cotton at the bottom of the clean water tank 4 and/or the bottom of the sewage tank 5, the contamination in the flowing water can be reduced.

In some embodiments, an air outlet 12 is provided in the recovery tank 5 . As shown in FIG. 5 , the air outlet can be arranged at the upper left of the sewage tank 5. The sewage tank 5 is also provided with a baffle plate. When there is too much garbage on the net 1, the space is a closed space.

In FIGS. 1 to 5 , the cross-sectional shape of the water storage area in the cleaning tray 6 is an ellipse. In some embodiments, the cross-sectional shape of the water storage area in the cleaning tray 6 can also be composed of two ellipses and a It consists of a rectangle connecting the above two ellipses, as shown in Figure 6.

Embodiment 2:

FIG. 7 shows a flowchart of a base station cleaning method provided by an embodiment of the present application. The base station cleaning method is applied to the base station in Embodiment 1. The structure of the base station is not repeated in this embodiment, and the main description is based on the base station. The structure of the base station cleaning method is detailed as follows:

In step S71, if a cleaning instruction is received, the electronically controlled valve is closed.

In this embodiment, when the base station detects that the cleaning robot has entered the base station, and/or detects that the self-cleaning function of the base station is activated, the base station determines that a cleaning instruction is received, and closes the electronically controlled valve. Among them, the self-cleaning function of the base station can be activated in the following ways: first, by the user pressing the self-cleaning function button set on the base station to start; second, it is controlled by the terminal device communicating with the base station. After the user controls the cleaning robot to enter the base station through the application on the mobile phone, and then starts the self-cleaning function of the base station through the application.

In this embodiment, closing the electronically controlled valve can avoid backflow of sewage caused by clogging of the filter screen.

In step S72, the clean water in the clean water tank is pumped to the cleaning tray by the first water pump.

In this embodiment, clean water in the clean water tank is pumped into the cleaning tray by the activated first water pump to clean the mop of the cleaning robot.

In some embodiments, the mop of the cleaning robot can be cleaned while the clean water in the clean water tank is drawn to the cleaning tray, or the mop of the cleaning robot can be cleaned after the clean water in the cleaning tray reaches a certain level.

In step S73, the sewage in the cleaning tray is sucked into the sewage tank by the first fan, and a filter screen is arranged above the sewage tank, and the filter screen is used to filter the garbage in the sewage entering the sewage tank.

When the cleaning robot is cleaned, the clean water in the cleaning tray will become sewage. At this time, the first fan will suck the sewage in the clean water tray into the sewage tank, and the sewage will be filtered by the filter set above the sewage tank. Into the sewage tank, the garbage in the sewage will stay on the filter screen.

In this embodiment, whether the cleaning robot has been cleaned can be judged by: judging whether the cleaning duration has reached the cleaning threshold, for example, if the cleaning threshold is 5 minutes, after cleaning the cleaning robot for 5 minutes, it is determined that the cleaning robot has been cleaned. It should be pointed out that the cleaning threshold is a dynamic threshold. For example, when the area cleaned by the cleaning robot is different, the corresponding cleaning threshold is also different. For example, when the area cleaned by the cleaning robot is a dirty area, the corresponding cleaning threshold Larger, anyway, the corresponding cleaning threshold is smaller.

Step S74, if the current of the first fan is greater than the preset current threshold, the electronically controlled valve is opened to suck out the garbage from the water inlet of the sewage tank and/or the filter screen.

The preset current threshold may be set to the rated current of the first fan, or may be set to a fixed current value, such as 1.5A.

In this embodiment, when a lot of garbage accumulates on the filter screen and blocks the filter screen, the space in the sewage tank formed by the filter screen and the closed electronically controlled valve is a closed space. At this time, the first fan It will be necessary to increase the rotation speed to suck the sewage from the cleaning tray into the sewage tank, that is, when the garbage on the filter screen accumulates a lot, the current of the first fan will increase. Therefore, after the base station determines that the current of the first fan is greater than the preset current threshold, the electric control valve is opened, and the activated first fan will drive the flow of gas, and suck out the water inlet of the sewage tank and/or the filter net from the opened electric control valve. Trash.

In some embodiments, step S74 is specifically as follows: if the current of the first fan is greater than the preset current threshold, and the duration of the current of the first fan that is greater than the current threshold is greater than the preset high current duration threshold, turn on the electronic control valve to suck out waste from the recovery tank inlet and/or strainer. For example, assuming that the preset high current duration threshold is 5 minutes, and from 12:3 to 12:10 (within 7 minutes), the current of the first fan is greater than the preset current threshold, then open the electronically controlled valve . Since the electronically controlled valve is opened only after it is determined that the duration of the high current (that is, the duration of the current of the first fan that is greater than the current threshold) is greater than the preset high current duration threshold, it is possible to avoid accidental anomalies due to the current ( Such as the wrong opening of the electronically controlled valve caused by the current being too large.

In some embodiments, step S74 includes:

If the current of the first fan is greater than the preset current threshold, the suction force of the first fan is increased, and the electronically controlled valve is opened.

In this embodiment, the suction force of the first fan can be increased by increasing the rotation speed of the first fan. For example, if the rotation speed of the first fan is A before it is determined that the current of the first fan is greater than the preset current threshold, Then, after it is determined that the current of the first fan is greater than the preset current threshold, the rotation speed of the first fan is B, and B is greater than A. Since the suction force of the first fan is increased, after the electronically controlled valve is opened, the speed of sucking out the garbage from the filter screen can be increased.

In some embodiments, step S74 includes:

If the current of the first fan is greater than the preset current threshold, the second fan is started and the electronically controlled valve is opened.

In this embodiment, the channel obtained by the open electronically controlled valve will be used as the channel for the garbage to come out of the filter screen. After the second fan of the base station is activated, the base station will quickly suck the garbage out of the filter through the combined action of the activated two fans (the first fan and the second fan). With the addition of a fan, the speed of sucking garbage out of the filter can be greatly increased.

In some embodiments, after step S73, it further includes:

If the current of the first fan is not greater than the preset current threshold, and the sewage recovery time is greater than the preset time threshold, the electronically controlled valve is opened to suck out the garbage from the water inlet of the sewage tank and/or the filter net, wherein the sewage recycling The duration is the duration that the first fan sucks the sewage in the cleaning tray into the sewage tank.

In this embodiment, when the time taken by the first fan to suck out the sewage from the cleaning tray is greater than the preset time length threshold, it indicates that the sewage recovery is completed. At this time, although it is not judged that the filter is blocked by garbage, the filter is cleaned It can shorten the time required for the subsequent filter screen to be blocked by garbage and then cleaned. Of course, if the base station further includes a second fan, the second fan is also activated when the electronically controlled valve is opened, so as to suck out the garbage from the water inlet of the sewage tank and/or the filter net through the first fan and the second fan. It should be pointed out that, since the water inlet and/or filter screen of the sewage tank are not blocked at this time, the suction force of the first fan can be maintained as it is, that is, the suction force of opening the electronically controlled valve can be kept the same.

In some embodiments, if the current of the first fan is not greater than the preset current threshold, and the sewage recovery time is greater than the preset time threshold, the electronically controlled valve is opened to suck out the water inlet of the sewage tank and/or filter After the garbage on the net, it includes: sucking the sewage in the sewage tank into the clean water tank through the second water pump.

In this embodiment, since the sewage in the sewage tank is sucked into the clean water tank, the base station realizes the recycling of water resources.

In some embodiments, step S74 includes:

If the current of the first fan is greater than the preset current threshold, the electronically controlled valve is opened to suck out the garbage from the water inlet of the sewage tank and/or the filter screen to the garbage box.

In this embodiment, in order to facilitate garbage collection, a garbage box is set in the base station, so that when the electronically controlled valve is opened, the garbage on the filter net is sucked out to the garbage box by the first fan. Of course, when the garbage is sucked out, the suction force of the first fan can be increased.

In some embodiments, if the base station is provided with two fans (a first fan and a second fan), the second fan is also activated when the electronically controlled valve is opened, and then the first fan and the second fan are used to connect the filter net suck out the garbage into the garbage bin.

In some embodiments, after step S74, including:

If the current of the first fan is not greater than the current threshold, the user is reminded to clean the sewage tank and/or the garbage box.

In this embodiment, the user can be reminded to clean the sewage tank and/or the garbage box by means of a voice broadcast or a warning light. Since the garbage blocked on the filter screen is cleaned, the current of the first fan will become smaller, and when the filter screen is blocked, it indicates that there is a lot of garbage. Therefore, in order to prevent the garbage in the garbage box from overflowing, after cleaning the filter Remind the user to clean the slop tank and/or litter box after rubbish on the web.

In some embodiments, after the sewage in the sewage tank is sucked into the clean water tank by the second water pump, the method includes:

It is judged whether the number of times of sewage recycling is greater than the preset times threshold, and if so, the user is reminded to clean the sewage tank and/or the garbage box.

In this embodiment, considering that when the number of times of sewage recycling is large, the garbage in the sewage tank and/or the garbage box is likely to be more. Therefore, reminding the user to clean the sewage tank and/or the garbage box in time can avoid the garbage in the garbage box. Spills, as well, improve the cleaning effect of the cleaning robot.
