In an actual use project, in order to safely replenish water, the invention further provides a water replenishing acceleration control mode, as shown in fig. 2, a control flow chart of water replenishing for the sweeper provided by the invention is shown, and as shown in fig. 6, a cross-sectional schematic view of the host machine entering the water replenishing cavity below the base station is provided. Referring to fig. 7, the present invention provides an enlarged view of a portion of fig. 6. The method comprises the following specific steps:
s10, when the low water level detection point 211 of the sweeper main machine 2 detects that the small water storage tank 21 in the main machine 2 is at a low water level, the sweeper main machine 2 automatically runs into the water supplementing cavity 11 at the bottom of the water supplementing base station 1, the butt joint port 22 of the main machine 2 is in positioning butt joint with the movable butt joint head 16 of the water supplementing base station 1 to form a water supplementing channel, and the large water storage tank 12 in the water supplementing base station 1 is located above the small water storage tank 21 to form a water level difference;
s20, when the main machine 2 moves into the water replenishing cavity 11 and is butted in place, closing a micro switch 28 to trigger the control valve 14 on the large water storage tank 12 in the base station 1 to be automatically opened, and under the action of water pressure, high-level water in the large water storage tank 12 rushes open the normally closed sealant 23 arranged in the water replenishing channel and flows into the small water storage tank 21 at a low water level, so that the water replenishing of the main machine 2 by the base station 1 is realized;
s30, when the high water level detection point 212 of the host machine 2 detects that the small water storage tank 21 is at a high water level, the control valve 14 on the large water storage tank 12 is triggered to be automatically closed;
s40, an overflow pipe 24 which can lead out the water at the upper part of the small water storage tank 21 is arranged on the side wall of the small water storage tank 21 close to the top, when the water level in the small water storage tank 21 exceeds the set water level (fault or reaction delay of the high water level detection point 212), the excess water is directly discharged out of the lower water storage tank through the overflow pipe 24 in an overflow way;
s50, when the main machine 2 detects that the small water storage tank 21 is at a low water level, the above steps are repeated.
It should be noted that the overflow pipe 24 disposed therein can rapidly discharge air at the upper portion of the small water storage tank 21 through the water pump 25 disposed therein, so as to form a certain negative pressure effect, thereby generating a "water absorption" effect, and further, the quick-locking water-replenishing control has a control mode of accelerating water-replenishing. Meanwhile, it is easy to understand that when the water replenishing speed is too fast, or when the high water level detection point 212 fails, the water in the small water storage tank 21 at the high level can be discharged in time through the overflow pipe 24, so that the pressure in the small water storage tank is reduced, the risks of water extrusion explosion, electric leakage and the like are prevented, and the safety of water replenishing is improved.
It can be understood that, in order to replenish water more safely and efficiently, the invention further provides a water replenishing acceleration control mode, as shown in fig. 2, a further control flow chart for replenishing water for the sweeper provided by the invention is shown, and as shown in fig. 6, a schematic cross-sectional view of the host machine entering the water replenishing cavity below the base station is shown. Referring to fig. 7, the present invention provides an enlarged view of a portion of fig. 6.
S100, when a low water level detection point 211 of a sweeper main machine 2 detects that a small water storage tank 21 in the main machine 2 is at a low water level, the sweeper main machine 2 automatically runs into a water supplementing cavity 11 at the bottom of a water supplementing base station 1, a butt joint port 22 of the main machine 2 is in positioning butt joint with a movable butt joint head 16 of the water supplementing base station 1 to form a water supplementing channel, and a large water storage tank 12 in the water supplementing base station 1 is located above the small water storage tank 21 to form a water level difference;
s200, when the main machine 2 moves into the water replenishing cavity 11 and is butted in place, closing a micro switch 28 to trigger a control valve 14 on a large water storage tank 12 in the base station 1 to be automatically opened, and flushing normally closed sealant 23 arranged in the water replenishing channel by high-level water in the large water storage tank 12 under the action of water pressure to flow into the small water storage tank 21 at a low water level, so that the water replenishing of the main machine 2 by the base station 1 is realized;

s400, when the high water level detection point 212 of the host machine 2 detects that the small water storage tank 21 is at a high water level, the water pump 25 stops; triggering the control valve 14 on the large reservoir 12 to close automatically;
s500, when the water level in the small water storage tank 21 exceeds a set water level (the high water level detection point 212 fails or is delayed in reaction or the power of the water pump 25 is too strong), the excessive water is directly discharged out of the lower water storage tank through the overflow pipe 24 in an overflowing way;
s600, when the main machine 2 detects that the small water storage tank 21 is at a low water level, the steps are repeated.
Preferably, to better ensure the overflow effect while preventing improper operation, the overflow pipe 24 is arranged to extend from one side wall inside the small reservoir 21 to the vicinity of the other side wall of the subject. One end of the small water storage tank 21 is extended, so that the space position of the overflow pipe 24 is reduced, and therefore when the main machine 2 is normally used for working, water in the small water storage tank 21 cannot be directly mistakenly shaken into the overflow pipe 24 to be discharged due to shaking, and misjudgment of a control system is caused.
As will be appreciated, without increasing safety, a sensor (not shown) may be provided in the overflow pipe 24 to close the control valve 14 for replenishing water as soon as an abnormal water flow phenomenon is detected therein, thereby achieving a secondary safety effect, preventing excessive overflow of water, causing flooding of the replenishing position, and additional cleaning.
Further, referring to fig. 8, the present invention provides a schematic partial sectional view of the connection of a water pump 25 in a main unit 2. And FIG. 9 is a partial sectional view of the connection of the water pump 25 in the main unit 2 according to the present invention. In order to more conveniently and reliably control the water replenishing, the overflow pipe 24 and the water outlet pipe 27 arranged on the side surface of the small water storage tank 21 can be connected to the same water pump 25 by arranging a two-position three-way valve 26; when water is required to be supplemented, the two-position three-way valve 26 conducts the overflow pipe 24 and the water pump 25, and cuts off the channel of the water outlet pipe 27 and the channel of the water pump 25.
When the refill water exceeds the high level set in the small reservoir 21, the excess water overflows through the overflow pipe 24 and is discharged.
Furthermore, in order to more accurately complete the positioning and butt joint, the water replenishing cavity 11 is arranged in a semi-open shape, and the movable butt joint 16 is convexly arranged at the bottom of the large water storage tank 12 and extends towards the direction of the main machine 2 entering the water replenishing cavity 11; the butt joint port 22 of the host machine 2 is matched with the movable butt joint 16 and is concave; the end of the docking interface 22 facing the mobile docking head 16 is provided with a tapered hole that guides the insertion of the mobile docking head 16. So, host computer 2 and basic station 1 are mechanical type plug butt joint, and in host computer 2 got into semi-uncovered style moisturizing chamber 11, the fault-tolerant space was big, and utilized the direction performance of the automatic centering of bell mouth, realized the butt joint in-process, host computer 2 need not the foreign object and assisted, alright accomplish the location butt joint, and the location is accurate high-efficient.
Still further, in order to improve the positioning efficiency of the host 2 and the base station 1, a carry channel 17 which is arranged in the water replenishing cavity 11 and used for guiding the host 2 to enter is arranged to be in a slope shape, and the slope of the carry channel 17 is arranged to be 5-8 degrees. When using, guide host computer 2 can get into moisturizing chamber 11 in, have a resistance brake function, easily realize the buffering location to host computer 2, more do benefit to accurate butt joint location, the location is efficient.
