The anti-overflow system of this basic station includes:
the anti-overflow mechanism 2 comprises at least two anti-overflow mechanisms 2, wherein all the anti-overflow mechanisms 2 are used for preventing liquid in the liquid storage tank 1 from overflowing, the anti-overflow mechanisms 2 can be mechanical anti-overflow mechanisms 2, the mechanical anti-overflow mechanisms 2 such as a baffle plate 21 open a liquid outlet 11, or electrical contact type anti-overflow mechanisms 2, and the electrical contact type anti-overflow mechanisms 2 such as a first sensing piece 22 are arranged for sensing the liquid level;
the reaction part 3 can perform at least two reactions along with the difference of the liquid level of the liquid storage tank 1, and when the reaction part 3 is in a first state that the liquid level is at a first height d1, the reaction part 3 triggers one of the spill-proof mechanisms 2 to work; when the reaction member 3 is in the second state that the liquid level is at the second height d2, the reaction member 3 triggers another spill prevention mechanism 2 to work, and the second height d2 can be seen in fig. 4. Specifically, in this embodiment, the reaction member 3 includes a floating member, and when the floating member floats to a first height d1, one of the spill-proof mechanisms 2 is triggered to operate, and when the floating member floats to a second height d2, the other spill-proof mechanism 2 is triggered to operate. The floating piece utilizes buoyancy, can rise to different heights along with the difference of the liquid level of the liquid storage tank 1, namely makes at least two reactions along with the difference of the liquid level of the liquid storage tank 1, and the floating piece can be a hollow and sealed part in a spherical shape, a columnar shape or other shapes, can be a hollow floating ball, and can also be a part made of a material with density smaller than that of water, so long as the floating piece can finally float on the water surface, and different reactions can be realized according to different floating height correspondences. In other embodiments, at least two groups of electrode plates arranged along the vertical height can be used for replacing the floating part, a single group of electrode plates comprises a positive electrode piece and a negative electrode piece, the corresponding electrode plate group can be conducted after the liquid level rises, the electrode plate group is electrically connected with a control panel, the control panel is electrically connected with an electromagnetic valve for controlling the liquid discharge channel or/and the liquid inlet channel in the liquid storage tank 1 to be electrically connected, and the electrode plate groups at different positions can react.
The working principle is as follows: reaction piece 3 is in during the liquid level is located the first state of first height d1, reaction piece 3 triggers one of them anti-overflow mechanism 2 works, realizes the first order anti-overflow, works as reaction piece 3 is in during the liquid level is located the second state of second height d2, reaction piece 3 triggers another anti-overflow mechanism 2 works, realizes second level anti-overflow and first order anti-overflow combined work, triggers two anti-overflow mechanisms 2 respectively on different liquid level height, and two anti-overflow mechanisms 2 can have the one-tenth anti-overflow, dual anti-overflow, and the anti-overflow effect is better.
When two or more spill-proof mechanisms 2 are combined, the two or more spill-proof mechanisms 2 may be combined together, or two or more different spill-proof mechanisms 2 may be combined together, in addition to the two or more same spill-proof mechanisms 2 being stacked together. At least one overflow prevention mechanism 2 is used for discharging the liquid in the liquid storage tank 1 or stopping the liquid from being input into the liquid storage tank 1. For example, when two overflow preventing mechanisms 2 are used, two overflow preventing mechanisms 2 for discharging the liquid in the liquid storage tank 1 may be combined, or two overflow preventing mechanisms 2 for stopping the liquid input into the liquid storage tank 1 may be combined, at this time, the two overflow preventing mechanisms 2 for discharging the liquid in the liquid storage tank 1 may be the same or different, and the two overflow preventing mechanisms 2 for stopping the liquid input into the liquid storage tank 1 may be the same or different. The spill-proof mechanisms 2 can be used for discharging liquid and stopping liquid entering, the spill-proof actions of the two spill-proof mechanisms 2 can be the same, the spill-proof actions can be more selective, and when the two spill-proof mechanisms 2 are used for discharging liquid or stopping liquid entering, the liquid discharging mode or the liquid entering stopping mode can be the same or different.
In order to further improve the anti-overflow effect caused by the combination of the anti-overflow mechanism 2, it is preferable that the anti-overflow mechanism 2 is arranged on the liquid storage tank 1 having a liquid inlet channel and a liquid outlet channel, in this case, one of the anti-overflow mechanisms 2 is used for discharging the liquid in the liquid storage tank 1, and the other anti-overflow mechanism 2 is used for stopping the liquid from being input into the liquid storage tank 1. The spill-proof action of the two spill-proof mechanisms 2 may be different. Specifically, the anti-overflow mechanism 2 triggered by the reaction member 3 in the first state is used for discharging the liquid in the liquid storage tank 1, the anti-overflow mechanism 2 triggered by the reaction member 3 in the second state is used for stopping the liquid from being input into the liquid storage tank 1, and the first height d1 is lower than the second height d 2. Along with the rising of liquid level height, can carry out earlier discharge liquid, stop the input liquid again, at this moment, the liquid of liquid reserve tank 1 reduces earlier, when the speed that reduces is less than the speed of input, the liquid level uprises, is in the action of another anti-overflow mechanism 2, stops the input liquid to guarantee that liquid can not spill over, this kind of mode can guarantee when one of them anti-overflow mechanism 2 discharge liquid, liquid reserve tank 1 can also carry out the feed liquor, guarantees that the feed liquor work of liquid reserve tank 1 can also normally go on when discharging.
For example, when the overflow prevention system of the base station is applied to the base station for cleaning the wiping member of the cleaning robot 4, and the floating member floats to the first height d1, one of the overflow prevention mechanisms 2 acts to discharge liquid, and at this time, the work of cleaning the wiping member is not affected, and the cleaning work is continued, and the following two cases can be divided: in the first situation, the liquid feeding speed is higher than the liquid discharging speed, the liquid level height continues to rise, when the liquid level height rises to the second height d2, the other anti-overflow mechanism 2 is triggered to act, and the liquid input is stopped, at this time, when one anti-overflow mechanism 2 works, the cleaning work can still be carried out, and the cleaning work is stopped when the second height d2 is reached, the liquid discharging can not affect the cleaning work as much as possible, the cleaning efficiency is improved, in the falling process, if the reaction member 3 with the sensed member 24 continues to swing upwards from the sensing range and exceeds the sensing range, the first sensing member 22 can be triggered again when the liquid falling process is carried out, so that the liquid feeding starts, the liquid feeding speed is higher than the liquid discharging speed, the cleaning can be carried out repeatedly, the cleaning time can be utilized to the greatest extent, of course, the reaction member 3 with the sensed member 24 can also not trigger the first sensing member 22, that is, the reaction member 3 falls back after being in the sensing range, and at this time, another sensing member may be set to trigger the liquid inlet to start, for example, a sensing member capable of sending a signal to enable the first control portion to control the liquid inlet channel to be opened is additionally provided on the rotation path such as the rotation starting point, so that the process of falling back to the rotation starting point can trigger the liquid inlet to start, and certainly, the sensing member may not be set to enable the liquid inlet to start; in the second case, the speed of the liquid feeding is less than the speed of the liquid discharging, so the liquid level height is maintained below the second height d2, the cleaning mop can be operated all the time, the cleaning operation is not affected, and the cleaning efficiency can be greatly improved compared with the case that a single anti-overflow mechanism 2 blocks the liquid feeding channel.
Of course, in another embodiment, the liquid input may be stopped before the liquid is discharged.
The above-mentioned spill prevention mechanism 2 for discharging the liquid of the liquid storage tank 1 may also have various embodiments, for example, it may include:
the baffle 21, the baffle 21 is connected with the leakage fluid port 11 of the liquid storage tank 1, and the floating piece is connected with the baffle 21 so as to open the leakage fluid port 11 to different degrees when the height of the floating piece is changed. By connecting the float member to the flap 21, the float member can open the flap 21 when the liquid level rises, utilizing buoyancy.
In the embodiment, the baffle 21 is rotatably connected to the liquid discharge port 11, and the baffle 21 can open the liquid discharge port 11 to different degrees when rotating; the floating piece is arranged at the free end of the baffle plate 21 and is positioned at one side of the baffle plate 21 facing the liquid storage tank 1. Through rotating the baffle 21 and connecting on the leakage fluid dram 11, can rise to when floating the piece height above at the liquid level, drive floating the piece through the liquid level with baffle 21 and leakage fluid dram 11 between the opening grow, when the liquid level rose, the degree of flowing back was also big more, and the anti-overflow is effectual. Wherein, because the floating member is located the baffle 21 orientation one side in the liquid reserve tank 1, consequently, the position of floating member and pin joint is not on same vertical line, and liquid can be decomposed into partly promotion floating member pivoted effort to the ascending buoyancy that the floating member brought, and articulated position is located the top, and the position from the end is located the below, consequently, when the liquid level rose, liquid can drive floating member and baffle 21 and rotate, and when the liquid level declined, gravity can drive the downward rotation of floating member.
Of course, the baffle 21 may be disposed at the liquid discharge port 11 in other manners, for example, in another embodiment, the baffle 21 may be disposed at the liquid discharge port 11 in a sliding manner, as shown in fig. 8 to 10.
The above-mentioned spill-proof mechanism 2 for stopping the liquid from being supplied to the liquid storage tank 1 may have various embodiments, for example, in the present embodiment, it may include:

the first control part is respectively electrically connected with the first sensing part 22 and the electromagnetic valve, and is used for receiving a first signal sent by the first sensing part 22 and outputting a first control signal according to the first signal so as to control the on-off of the electromagnetic valve.
And in another embodiment, the anti-overflow mechanism 2 for stopping liquid from entering the liquid storage tank 1 may further include a second sensing member 23, so as to realize the combination of the anti-overflow mechanism 2 in a pure electric touch response, or a combination of a plurality of anti-overflow mechanisms 2, as shown in fig. 11 in particular.

In another embodiment, the sensed member 24 may also be a proximity switch, when the sensed member 24 as a floating member rises to be within the sensing range of the proximity switch, the proximity switch sends a signal to the control portion, the control portion controls the electromagnetic valve to block the liquid inlet channel, and when the sensed member 24 is the proximity switch, the sensed member 24 may be an extension structure on the reaction member 3 for being sensed, or may be the reaction member 3 itself. Of course, in other embodiments, the sensed object 24 and the sensing element can be other components for sensing that an object falls within the sensing range.
The working principle is as follows: through setting up first control part and the first response piece 22 of being connected with first control part electricity, first response piece 22 can respond to length, width or the partial range of height in the liquid reserve tank 1 to when reaction piece 3 gets into this response scope, send first signal to first control part, first control part is according to this first control signal of signal output, with the break-make of control solenoid valve control inlet channel, prevent that liquid from getting into liquid reserve tank 1, thoroughly solve the liquid level and rise the problem of spilling over. Specifically, the first sensing member 22 may sense a partial range of the height in the reservoir 1. While in other embodiments the first sensing member 22 may sense a partial range of the length, see fig. 5, in alternate embodiments the first sensing member 22 may also sense a partial range of the width, see fig. 6 and 7.

The working principle is as follows: when the liquid level rises, the baffle 21 rotates upwards, the floating piece with the sensed piece 24 can open the liquid outlet 11 to discharge liquid mechanically, if the liquid discharge speed is less than the liquid inlet speed, the first sensing piece 22 is triggered in the length direction, the first sensing piece 22 triggers the electromagnetic valve to control one of the liquid inlet channels to stop liquid inlet, in the first case, the liquid discharge speed is less than the liquid inlet speed, the reaction piece 3 drives the baffle 21 to continue to rotate upwards to trigger the second sensing piece 23, at the moment, the two liquid inlet channels stop liquid inlet, the baffle 21 falls back, the second sensing piece 23 is in the sensing range of the second sensing piece 23 when being positioned at the highest liquid level, therefore, the second sensing piece cannot enter the sensing range of the second sensing piece 23 again when falling back, in the falling process, when falling back to trigger the first sensing piece 22, the first sensing piece 22 sends a third signal, the first control part receives the third signal, and outputting a third control signal according to a third signal to control the electromagnetic valve to open the liquid inlet channel corresponding to the first sensing element 22, at this time, an additional sensing element capable of sending a signal to enable the first control part to control the liquid inlet channel corresponding to the second sensing element 23 to be kept open may be additionally arranged on the rotation path of the rotation starting point, so that the liquid inlet of another liquid inlet channel can be triggered to start by the sensing element 24 in the process that the baffle 21 falls back to the rotation starting point, and certainly, the liquid inlet of another liquid inlet channel can also start without the sensing element. In the process of falling back, because one of them inlet channel is opened, if the flowing back speed still is less than the inlet velocity, baffle 21 can continue upwards to rotate and trigger second response piece 23 to the repeated falling back and the stack action that rises and form, constantly feed liquor with the time that utilizes this process, when the expression is on the basic station that is used for washing the piece of mopping, can utilize the time cleanness by the at utmost, improve clean efficiency, if the flowing back speed is greater than the inlet velocity, rotate the initial point position when baffle 21 falls back. In the second case, if the liquid discharge velocity is greater than the liquid inlet velocity, the flap 21 falls back and the liquid level drops to the first height d 1.
As shown in fig. 6 and 7, fig. 6 is a schematic view of the first sensing element and the second sensing element forming different sensing regions in the width direction, and fig. 7 is a schematic view of the reaction element of the modification in the second state.
The operation principle is the same as that of the embodiment shown in fig. 5, and will not be described again here.

The baffle 21 can be slidably connected to the liquid outlet 11, specifically, the baffle 21 and the liquid outlet 11 are vertically attached to each other, and a hollow limiting member is disposed in the liquid storage tank 1, and is used for loading the reaction member 3 and limiting the reaction member 3 from disengaging from the limiting member.
Stretch out connecting portion from the locating part on the reaction 3, the one end of this connecting portion is connected with reaction 3, the other end is connected with baffle 21, wherein, be provided with the bar opening that sets up along vertical direction of height on the locating part, connecting portion and this bar opening sliding connection, when reaction 3 rose, drive connecting portion upwards slided for the bar opening, baffle 21 opened leakage fluid dram 11, carry out the flowing back, and the degree of opening increases along with high rising, when reaction 3 descends, drive connecting portion and slide down for the bar opening, baffle 21 closes leakage fluid dram 11, and the degree of closing increases along with high decline.
The working principle is as follows: when the reaction member 3 ascends, in the first situation, if the liquid inlet speed is greater than the liquid discharge speed, the reaction member 3 continuously ascends to the second height d2, the sensed member 24 on the reaction member 3 enters the sensing range of the first sensing member 22, the first sensing member 22 is triggered to send out a first signal, and the first control part receives the first signal and outputs a first control signal according to the first signal so as to control the electromagnetic valve to control the liquid inlet channel to be closed. When reaction piece 3 fell back this moment, first response piece 22 can also send and sense the fourth signal that is broken away from the response scope by response piece 24, first control division can open liquid inlet channel according to fourth signal output fourth control signal control solenoid valve, if liquid inlet speed is greater than the flowing back speed after opening, then reaction piece 3 continues to rise and triggers first response piece 22 for first control division output first signal control liquid inlet channel blocks, go on with this is reciprocal, with the maximum increase feed liquor, when showing in the basic station that is used for cleaning the piece of wiping, can increase clean water as far as, in order to improve clean efficiency. If the liquid inlet speed is lower than the liquid discharge speed after opening, the reaction member 3 descends and drives the baffle plate 21 to finally close the liquid discharge port 11. In the second case, if the liquid feeding speed is lower than the liquid discharging speed, the reaction member 3 descends and drives the baffle 21 to move until the reaction member 3 is at the first height d1, and the baffle 21 closes the liquid discharging port 11.
In the above embodiments, the liquid outlet 11 may be connected to the outside, such as a floor drain, to directly discharge the liquid or may be connected to a spare first liquid storage space, for example, a liquid storage transfer cavity is further disposed below, on the side, or above the liquid storage tank 1; when the transfer chamber of stock solution sets up in 1 below of liquid reserve tank or side, can also set up the second stock solution space that is located 1 top of liquid reserve tank on the basis of transfer chamber of stock solution again, at this moment, the transfer chamber of stock solution can set up a passageway intercommunication to second stock solution space, and absorb the liquid of transfer chamber in the stock solution to second stock solution space through the booster pump, the excessive problem of liquid that the flowing back passageway blockked up and cause can be avoided to this kind of structure, highly higher leakage fluid dram 11 can not blockked up by the filth of sinking, can shift the liquid in first stock solution space to second stock solution space through the booster pump, the booster pump also can be the same booster pump that the flowing back passageway adopted, also can be the booster pump that sets up in addition.
