背景技术Background technique

现有的用于洗拖布的基站，在清洗拖布的过程中，需要持续的将清水加入清洁槽体中，以将拖布清洗干净，然而现有的单一的用电极片组感应液位高度的方式难以满足清洁需求，现有的基站通常在污水箱中一定高度上设置正负电极片，在液位上升至电极片组的位置时，电极片组给出导通信号，传输给控制板，通过控制板连接蜂鸣器提示水满。In the existing base station for cleaning the mop, in the process of cleaning the mop, it is necessary to continuously add clean water to the cleaning tank to clean the mop. However, the existing single electrode group is used to sense the liquid level. It is difficult to meet the cleaning needs. In the existing base station, positive and negative electrode plates are usually set at a certain height in the sewage tank. When the liquid level rises to the position of the electrode plate group, the electrode plate group sends a conduction signal and transmits it to the control board. The buzzer connected to the control board indicates that the water is full.

这种结构的水满检测机制，在提示水满时没有对污水进行处理，容易出现溢出的问题，不具备防溢作用。The water full detection mechanism of this structure does not treat the sewage when it indicates that the water is full, which is prone to overflow problems and does not have the function of preventing overflow.

When the reaction part 3 is in the second state where the liquid level is at the second height d2, the reaction part 3 triggers another overflow prevention mechanism 2 to work, so that the second-level overflow prevention and the first-level overflow prevention work together. , the two overflow prevention mechanisms 2 are triggered respectively at different liquid level heights, and the two overflow prevention mechanisms 2 can perform overflow prevention in layers, double overflow prevention, and the overflow prevention effect is better.

两个以上防溢机构2配合时，两个以上的防溢机构2在进行组合时除了可以是两个以上相同的防溢机构2进行叠加，也可以是两个以上不同的防溢机构2进行组合。其中，至少一所述防溢机构2用于排出所述储液箱1的液体或停止液体输入所述储液箱1。比如，采用两个防溢机构2时，可以是两个用于排出所述储液箱1的液体的防溢机构2进行组合，也可以是两个用于停止液体输入所述储液箱1的防溢机构2进行组合，此时，两个用于排出所述储液箱1的液体的防溢机构2可以相同，也可以不同，两个用于停止液体输入所述储液箱1的防溢机构2可以相同，也可以不同。防溢机构2可以用于排出液体，也可以用于停止进入液体，两个防溢机构2的防溢动作还可以相同，防溢动作可选择性多，在两个防溢机构2都用于排出液体或都用于停止进入液体时，排出液体方式或停止进入液体方式可以相同，也可以不同。When two or more overflow prevention mechanisms 2 cooperate, the combination of two or more overflow prevention mechanisms 2 may not only be superimposed by two or more identical overflow prevention mechanisms 2, but also may be implemented by two or more different overflow prevention mechanisms 2. combination. Wherein, at least one of the anti-overflow mechanisms 2 is used to discharge the liquid in the liquid storage tank 1 or stop the liquid input into the liquid storage tank 1 . For example, when two overflow prevention mechanisms 2 are used, two overflow prevention mechanisms 2 for discharging the liquid in the liquid storage tank 1 may be combined, or two overflow prevention mechanisms 2 for stopping the liquid input into the liquid storage tank 1 may be combined. The two overflow prevention mechanisms 2 are combined. At this time, the two overflow prevention mechanisms 2 used to discharge the liquid in the liquid storage tank 1 may be the same or different. The overflow prevention mechanism 2 may be the same or different. The anti-overflow mechanism 2 can be used to discharge liquid or stop the liquid from entering. The anti-overflow action of the two anti-overflow mechanisms 2 can also be the same, and the anti-overflow action can be more selective. When the liquid is discharged or both are used to stop entering the liquid, the method of discharging the liquid or the method of stopping the entering of the liquid may be the same or different.

为了进一步提高防溢机构2的组合所带来的防溢效果，优选在具有进液通道和排液通道的储液箱1上，此时，其中一所述防溢机构2用于排出所述储液箱1的液体，另外一所述防溢机构2用于停止液体输入所述储液箱1。两个防溢机构2的防溢动作可以不同。具体的，所述反应件3处于第一状态触发的所述防溢机构2用于排出所述储液箱1的液体，所述反应件3处于第二状态触发的所述防溢机构2用于停止液体输入所述储液箱1，且所述第一高度d1比第二高度d2低。随着液位高度的上升，可以先进行排出液体，再停止输入液体，此时，储液箱1的液体先减少，在减少的速度慢于输入的速度时，液位变高，处于另外一防溢机构2动作，停止输入液体，以保证液体不会溢出，这种方式可以保证在其中一防溢机构2排出液体时，储液箱1还可以进行进液，保证储液箱1的进液工作在排出时还能够正常进行。In order to further improve the overflow prevention effect brought by the combination of the overflow prevention mechanism 2, it is preferable to use the liquid storage tank 1 with a liquid inlet channel and a liquid discharge channel. For the liquid in the liquid storage tank 1 , another anti-overflow mechanism 2 is used to stop the liquid input into the liquid storage tank 1 . The overflow prevention actions of the two overflow prevention mechanisms 2 may be different. Specifically, the overflow prevention mechanism 2 triggered by the reaction member 3 in the first state is used to discharge the liquid in the liquid storage tank 1 , and the overflow prevention mechanism 2 triggered by the reaction member 3 in the second state is used for After stopping the liquid input into the liquid storage tank 1, the first height d1 is lower than the second height d2. As the height of the liquid level rises, the liquid can be discharged first, and then the liquid input can be stopped. At this time, the liquid in the liquid storage tank 1 decreases first, and when the decreasing speed is slower than the input speed, the liquid level becomes higher and is in another The anti-overflow mechanism 2 acts to stop the input of liquid to ensure that the liquid will not overflow. This method can ensure that when one of the anti-overflow mechanisms 2 discharges the liquid, the liquid storage tank 1 can still be filled with liquid to ensure that the liquid storage tank 1 enters the liquid. The liquid work can also be carried out normally when it is discharged.

比如，在基站的防溢***应用在清洁清洁机器人4的拖擦件的基站上时，浮动件上浮至第一高度d1时，其中一防溢机构2动作，开始排出液体，此时清洁拖擦件的工作不受影响，继续清洁工作，后续可以分成两种情况：第一种情况，进液的速度大于排液的速度，那么液位高度继续上升，当液位高度上升至第二高度d2时，触发另一防溢机构2动作，并停止输入液体，此时，在一个防溢机构2工作时，清洁工作仍然可以进行，并在达到第二高度d2时才停止，能够让排液尽可能的不影响清洁工作，提高清洁效率，在回落过程中，带有被感应件24的反应件3如果从感应范围中继续向上摆动并超过感应范围，回落时可以再次触发第一感应件22，使得进液开始，进液速度大于排液速度时可以往复进行，最大程度利用可清洁时间的进行清洁，当然，回落过程中，带有被感应件24的反应件3也有可能不触发第一感应件22，也即反应件3处于感应范围后回落，此时可以设置另外的感应件触发进液开始，比如在如转动起始点的转动路径上另外设置能够发出信号让第一控制部控制进液通道保持开启的感应件，使得回落至转动起始点的过程能够触发进液开始，当然，也可以不设置该感应件让进液开始；第二种情况，进液的速度小于排液的速度，那么液位高度维持在第二高度d2以下，清洁拖擦件的工作可以一直进行，完全不会影响清洁工作，比起单独一个防溢机构2将进液通道阻断时，能够极大的提高清洁效率。For example, when the overflow prevention system of the base station is applied to the base station for cleaning the mopping member of the cleaning robot 4, when the floating member floats up to the first height d1, one of the anti-spill mechanisms 2 operates and starts to discharge the liquid. At this time, the cleaning mop The work of the parts is not affected, and the cleaning work is continued. The follow-up can be divided into two cases: the first case, the speed of liquid inlet is greater than the speed of liquid discharge, then the liquid level continues to rise, and when the liquid level rises to the second height d2 At this time, the action of another anti-overflow mechanism 2 is triggered, and the input of liquid is stopped. At this time, when one anti-overflow mechanism 2 is working, the cleaning work can still be carried out, and it will stop when the second height d2 is reached, which can make the liquid drain completely. It may not affect the cleaning work and improve the cleaning efficiency. In the process of falling back, if the reaction member 3 with the sensing member 24 continues to swing upward from the sensing range and exceeds the sensing range, the first sensing member 22 can be triggered again when falling back. Make the liquid feeding start, and the liquid feeding speed can be reciprocated when the liquid feeding speed is greater than the liquid discharging speed, and the cleaning time can be used to the maximum extent. 22, that is, the reaction element 3 falls back after it is in the sensing range. At this time, another sensing element can be set to trigger the start of liquid feeding. For example, an additional setting on the rotation path such as the starting point of rotation can send a signal to let the first control part control the liquid feeding. The induction member whose channel remains open enables the process of falling back to the starting point of rotation to trigger the start of liquid inflow. Of course, it is also possible to not set the induction member to allow liquid inflow to start; Then the height of the liquid level is maintained below the second height d2, the work of cleaning the mopping parts can be carried out all the time, and the cleaning work will not be affected at all. cleaning efficiency.

当然，在另一实施例中，也可以先停止输入液体，再进行排出液体。Of course, in another embodiment, the liquid input can also be stopped first, and then the liquid can be discharged.

上述的用于排出所述储液箱1的液体的防溢机构2也可以有多种实施方式，比如，其可以包括：The above-mentioned anti-overflow mechanism 2 for discharging the liquid in the liquid storage tank 1 may also have various implementations, for example, it may include:

挡板21，所述挡板21与储液箱1的排液口11连接，所述浮动件与所述挡板21连接，以在所述浮动件高度变化时不同程度的打开所述排液口11。通过将浮动件和挡板21连接，利用浮力，在液位上升时浮动件可以将挡板21打开。The baffle 21, the baffle 21 is connected with the liquid discharge port 11 of the liquid storage tank 1, and the floating member is connected with the baffle 21, so as to open the discharge to different degrees when the height of the floating member changes mouth 11. By connecting the floating member to the baffle 21, the floating member can open the baffle 21 when the liquid level rises by utilizing buoyancy.

在本实施例中，所述挡板21转动连接在所述排液口11上，所述挡板21转动时能够不同程度地打开所述排液口11；所述浮动件设置在所述挡板21的自由端，并位于所述挡板21朝向所述储液箱1内的一侧。通过将挡板21转动连接在排液口11上，可以在液位上升至浮动件高度以上时，通过液位带动浮动件以将挡板21与排液口11之间开口变大，在液位上升时，排液的程度也就越大，防溢效果好。其中，由于浮动件位于所述挡板21朝向所述储液箱1内的一侧，因此，浮动件与铰接点的位置不在同一竖直线上，液体对浮动件带来的向上的浮力可以分解为一部分是推动浮动件转动的作用力，而铰接的位置位于上方，自端的位置位于下方，因此，液位上升时，液体可以带动浮动件和挡板21转动，液位下降时，重力可以带动浮动件向下转动。In this 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 it rotates; The free end of the plate 21 is located on the side of the baffle plate 21 facing the inside of the liquid storage tank 1 . By rotatably connecting the baffle 21 to the liquid discharge port 11, when the liquid level rises above the height of the floating member, the floating member can be driven by the liquid level to enlarge the opening between the baffle 21 and the liquid discharge port 11. When the level rises, the degree of drainage is greater, and the overflow prevention effect is good. Wherein, since the floating member is located on the side of the baffle plate 21 facing the liquid storage tank 1, the position of the floating member and the hinge point are not on the same vertical line, and the upward buoyancy force brought by the liquid to the floating member can be It is decomposed into a part of the force that pushes the floating piece to rotate, and the hinged position is at the top and the self-end position is at the bottom. Therefore, when the liquid level rises, the liquid can drive the floating member and the baffle 21 to rotate, and when the liquid level drops, the gravity can Drive the floating piece to rotate downward.

当然，挡板21也可以以其他方式设置在排液口11处，比如在另外一实施例中，该挡板21可以通过滑动连接的方式设置在排液口11处，具体可见图8至图10。Of course, the baffle 21 may also be disposed at the liquid discharge port 11 in other ways. For example, in another embodiment, the baffle 21 may be disposed at the liquid discharge port 11 by sliding connection, as shown in FIG. 8 to FIG. 8 . 10.

上述的用于停止液体输入所述储液箱1的防溢机构2也可以有多种实施方式，比如，在本实施例中，其可以包括：The above-mentioned anti-overflow mechanism 2 for stopping the liquid input into the liquid storage tank 1 may also have various implementations. For example, in this embodiment, it may include:

并且在另外的实施方式中，所述停止液体进入所述储液箱1的防溢机构2还可以包括第二感应件23，以实现纯电触感应时的防溢机构2组合，或者多个防溢机构2组合，具体可见图11。And in another embodiment, the overflow prevention mechanism 2 for stopping the liquid from entering the liquid storage tank 1 may further include a second sensing member 23, so as to realize the combination of the overflow prevention mechanism 2 during pure electric touch sensing, or multiple The combination of overflow prevention mechanism 2 is shown in Figure 11 for details.

在本实施例中，被感应件24可以是磁性体，比如可以是磁条，磁片或磁块等等，感应件可以是霍尔传感器，可以将磁性体设置在反应件3上，作为浮动件的被感应件24上升至处于霍尔传感器的感应范围内时，霍尔传感器发送信号至控制部，控制部控制电磁阀将进液通道阻断，具体的，可以是在浮动件上贴有磁条，或者用磁片贴满浮动件的表面。在另一实施方式中，被感应件24也可以接近开关，作为浮动件的被感应件24上升至处于接近开关的感应范围内时，接近开关发送信号至控制部，控制部控制电磁阀将进液通道阻断，在被感应件24为接近开关时，被感应件24可以是反应件3上便于被感应的延长结构，也可以是反应件3本身。当然，在其他的实施方式中，被感应件24和感应件还可以是其他的用来感应物体落入感应范围的部件。In this embodiment, the sensing member 24 may be a magnetic body, such as a magnetic strip, a magnetic sheet or a magnetic block, etc. The sensing member may be a Hall sensor, and the magnetic body may be arranged on the reaction member 3 as a floating When the sensed part 24 of the part rises to be within the sensing range of the Hall sensor, the Hall sensor sends a signal to the control part, and the control part controls the solenoid valve to block the liquid inlet channel. Magnetic strips, or cover the surface of the float with a magnetic sheet. In another embodiment, the sensed part 24 can also be close to the switch. When the sensed part 24 as a floating part rises to be within the sensing range of the proximity switch, the proximity switch sends a signal to the control part, and the control part controls the solenoid valve to enter the The liquid channel is blocked. When the sensing member 24 is a proximity switch, the sensing member 24 can be an elongated structure on the reaction member 3 that is easy to be sensed, or it can be the reaction member 3 itself. Of course, in other embodiments, the sensing member 24 and the sensing member may also be other components used to sense objects falling into the sensing range.

工作原理：通过设置第一控制部以及与第一控制部电连接的第一感应件22，所述第一感应件22能够感应所述储液箱1中的长度、宽度或高度的部分范围，以在反应件3进入该感应范围时，发送第一信号至第一控制部，所述第一控制部根据该第一信号输出第一控制信号，以控制电磁阀控制进液通道的通断，阻止液体进入储液箱1，彻底解决液位上升溢出的问题。具体的，此处的第一感应件22可以感应储液箱1中高度的部分范围。而在其他实施方式中，第一感应件22可以感应长度的部分范围，可见图5，在变形实施方式中，第一感应件22还可以感应宽度的部分范围，可见图6和图7。Working principle: by arranging the first control part and the first sensing part 22 electrically connected to the first control part, the first sensing part 22 can sense a part of the length, width or height in the liquid storage tank 1, When the reaction element 3 enters the sensing range, a first signal is sent to the first control part, and the first control part outputs a first control signal according to the first signal, so as to control the solenoid valve to control the opening and closing of the liquid inlet channel, Prevent the liquid from entering the liquid storage tank 1, and completely solve the problem of liquid level rise and overflow. Specifically, the first sensing member 22 here can sense a partial range of heights in the liquid storage tank 1 . In other embodiments, the first sensing member 22 can sense a partial range of the length, as shown in FIG. 5 . In a variant embodiment, the first sensing member 22 can also sense a partial range of the width, as shown in FIGS. 6 and 7 .

如图2至图4所示，图2是反应件处于第一状态的示意图，图3是反应件处于第一状态和第二状态之间的过渡状态的示意图，图4是反应件处于第二状态的示意图。As shown in FIGS. 2 to 4 , FIG. 2 is a schematic diagram of the reaction element in the first state, FIG. 3 is a schematic diagram of the reaction element in the transition state between the first state and the second state, and FIG. 4 is the reaction element in the second state. Schematic diagram of the state.

图2至图4示出了反应件3触发两个防溢机构2的整个过程，在该过程中储液箱1具有不同高度的液位，在所述反应件3处于液位位于第一高度d1的第一状态时，所述反应件3触发其中一所述防溢机构2工作，此时机械式的防溢机构2开始工作，在液位在第一高度d1上升至第二高度d2的过程，挡板21向上转动，挡板21与排液口11之间的开口逐渐变大，排液速度越来越快，在所述反应件3上升至处于所述液位位于第二高度d2的第二状态时，所述反应件3触发第一感应件22，第一感应件22可以传输信号至第一控制部，第一控制部根据该信号输出控制信号，以控制与进液通道的电磁阀将进液通道阻断。Figures 2 to 4 show the entire process of triggering the two overflow prevention mechanisms 2 by the reaction piece 3. During this process, the liquid storage tank 1 has liquid levels of different heights. When the reaction piece 3 is at the liquid level at the first height In the first state of d1, the reaction element 3 triggers one of the anti-overflow mechanisms 2 to work. At this time, the mechanical anti-overflow mechanism 2 starts to work, and the liquid level rises from the first height d1 to the second height d2. During the process, the baffle 21 rotates upward, the opening between the baffle 21 and the liquid discharge port 11 gradually becomes larger, and the liquid discharge speed becomes faster and faster. When the reaction member 3 rises to the second height d2 at the liquid level In the second state, the reaction part 3 triggers the first sensing part 22, the first sensing part 22 can transmit a signal to the first control part, and the first control part outputs a control signal according to the signal to control the connection with the liquid inlet channel. The solenoid valve blocks the liquid inlet channel.

并且被感应件24此时可以是磁条，反应件3可以是中空的能够在液体上浮动的柱体，磁条粘贴在反应件3朝向第一感应件22的位置，或者粘贴在第一感应件的周向，以便于被第一感应件22感应。And the sensed part 24 can be a magnetic strip at this time, the reaction part 3 can be a hollow cylinder that can float on the liquid, and the magnetic strip is pasted on the position of the reaction part 3 toward the first induction part 22, or pasted on the first induction part. The circumferential direction of the element is easy to be sensed by the first sensing element 22 .

如图5所示，图5是第一感应件和第二感应件形成长度方向上的不同感应区域的示意图。As shown in FIG. 5 , FIG. 5 is a schematic diagram illustrating that the first sensing element and the second sensing element form different sensing regions in the length direction.

所述停止液体进入所述储液箱1的防溢机构2除了可以包括第一感应件22外，还可以包括：In addition to the first sensing member 22, the overflow prevention mechanism 2 for stopping the liquid from entering the liquid storage tank 1 may also include:

第二感应件23，所述第二感应件23与所述第一控制部电连接，所述第一控制部能够接收所述第二感应件23发出的第二信号，并根据该第二信号输出第二控制信号以控制所述电磁阀的通断；所述第二感应件23的感应范围覆盖所述储液箱1中的长度、宽度或高度的部分范围，且所述第二感应件23的感应范围与所述第一感应件22的感应范围形成在长度、宽度或高度方向上的不同感应区域。通过设置第二感应件23，第二感应件23与第一控制部连接，第二感应件23在所述储液箱1中的长度、宽度或高度上与所述第一感应件22形成不同感应区域，以两次阻断进液。此时，两次阻断进液的进液通道可以相同也可以不同。The second sensing element 23, the second sensing element 23 is electrically connected to the first control part, the first control part can receive the second signal sent by the second sensing element 23, and according to the second signal A second control signal is output to control the on-off of the solenoid valve; the sensing range of the second sensing element 23 covers part of the length, width or height of the liquid storage tank 1 , and the second sensing element The sensing range of 23 and the sensing range of the first sensing element 22 form different sensing regions in the direction of length, width or height. By disposing the second sensing element 23, the second sensing element 23 is connected to the first control part, and the length, width or height of the second sensing element 23 in the liquid storage tank 1 is different from the first sensing element 22. Sensing area to block the influx twice. At this time, the liquid inlet channels that block the liquid inlet twice may be the same or different.

其中，第一感应件22和第二感应件23可以在储液箱1形成长度方向上的不同感应区域，第一感应件22和第二感应件23沿储液箱1的长度方向设置。The first sensing member 22 and the second sensing member 23 may form different sensing regions in the length direction of the liquid storage tank 1 , and the first sensing member 22 and the second sensing member 23 are arranged along the length direction of the liquid storage tank 1 .

两个感应件可以对应两个进液通道的通断，或对应控制两个将液体从外界连通至储液箱1的进液口的开合。The two sensing elements can correspond to the on-off of the two liquid inlet channels, or correspondingly control the opening and closing of the two liquid inlet ports that communicate the liquid from the outside to the liquid storage tank 1 .

工作原理：液位上升时，挡板21向上转动，带有被感应件24的浮动件可以先打开排液口11进行机械式的排液，如果排液速度小于进液速度，长度方向上先触发第一感应件22，第一感应件22触发电磁阀控制其中一个进液通道停止进液，第一种情况时，排液速度还是小于进液速度，反应件3带动挡板21继续向上转动，以触发第二感应件23，此时，两个进液通道均停止进液，挡板21回落，由图可见第二感应件23位于最高液位时处于第二感应件23的感应范围，因此回落时不会再次进入第二感应件23的感应范围，回落过程中，在回落至触发第一感应件22时，第一感应件22发出第三信号，第一控制部接收第三信号，并根据第三信号输出第三控制信号控制电磁阀打开第一感应件22对应的进液通道，此时，可以在如转动起始点的转动路径上另外设置能够发出信号让第一控制部控制第二感应件23对应的进液通道保持开启的感应件，使得挡板21回落至转动起始点的过程中能够通过被感应件24触发另一进液通道的进液开始，当然，也可以不设置该感应件让另一进液通道的进液开始。在回落过程中，由于其中一个进液通道打开，如果排液速度还是小于进液速度，挡板21会继续向上转动触发第二感应件23，并重复回落和上升形成的叠加动作，以利用该过程的时间不断进液，表现在用于洗拖擦件的基站上时，能够最大程度利用时间清洁，提高清洁效率，如果排液速度大于进液速度，挡板21回落时转动起始点位置。第二种情况时，如果排液速度大于进液速度，挡板21回落，液位降低至第一高度d1。Working principle: When the liquid level rises, the baffle plate 21 rotates upward, and the floating part with the sensed part 24 can first open the liquid discharge port 11 for mechanical liquid discharge. The first induction member 22 is triggered, and the first induction member 22 triggers the solenoid valve to control one of the liquid inlet channels to stop liquid feeding. In the first case, the liquid discharge speed is still lower than the liquid inlet speed, and the reaction member 3 drives the baffle 21 to continue to rotate upward. , to trigger the second sensing element 23. At this time, the two liquid inlet channels stop feeding liquid, and the baffle 21 falls back. It can be seen from the figure that the second sensing element 23 is in the sensing range of the second sensing element 23 when it is at the highest liquid level. Therefore, when falling back, it will not enter the sensing range of the second sensing element 23 again. During the falling process, when falling back to trigger the first sensing element 22, the first sensing element 22 sends a third signal, and the first control unit receives the third signal. And output the third control signal according to the third signal to control the solenoid valve to open the liquid inlet channel corresponding to the first induction member 22. At this time, an additional setting can be provided on the rotation path such as the starting point of rotation that can send a signal to let the first control part control the first control part. The sensing member corresponding to the liquid inlet channel of the two sensing members 23 is kept open, so that the baffle 21 can be triggered by the sensing member 24 to start the liquid feeding of the other liquid inlet channel during the process of falling back to the starting point of rotation. Of course, it is not necessary to set The sensing element starts the liquid feeding of another liquid feeding channel. In the process of falling back, since one of the liquid inlet channels is open, if the liquid discharge speed is still lower than the liquid inlet speed, the baffle 21 will continue to rotate upward to trigger the second sensing member 23, and repeat the superimposed action formed by falling back and rising, so as to utilize the During the process, the liquid is continuously fed, which is reflected in the base station used for cleaning the mopping parts, which can maximize the use of time to clean and improve the cleaning efficiency. If the liquid discharge speed is greater than the liquid feeding speed, the baffle 21 will rotate to the starting point position when it falls back. In the second case, if the liquid discharging speed is greater than the liquid feeding speed, the baffle 21 falls back, and the liquid level decreases to the first height d1.

如图6和图7所示，图6是第一感应件和第二感应件形成宽度方向上的不同感应区域的示意图，图7是变形例的反应件处于第二状态的示意图。As shown in FIG. 6 and FIG. 7 , FIG. 6 is a schematic diagram of the first sensing element and the second sensing element forming different sensing regions in the width direction, and FIG. 7 is a schematic diagram of the reaction element of the modification in the second state.

第一感应件22和第二感应件23还可以在储液箱1形成宽度方向上的不同感应区域，第一感应件22和第二感应件23沿储液箱1的宽度方向设置，这种两个防溢机构2的组合，通过作为浮力件的反应件3带动挡板21相对于排液口11进行转动，来控制排液口11与挡板21之间的开口大小，并结合其中一个防溢机构2的第一感应件22，和另外一个防溢机构2的第二感应件23，可以有效进行双重防溢。The first sensing member 22 and the second sensing member 23 may also form different sensing regions in the width direction of the liquid storage tank 1. The first sensing member 22 and the second sensing member 23 are arranged along the width direction of the liquid storage tank 1. The combination of the two overflow prevention mechanisms 2 drives the baffle plate 21 to rotate relative to the liquid discharge port 11 through the reaction member 3 as the buoyancy member, so as to control the size of the opening between the liquid discharge port 11 and the baffle plate 21, and combine one of them. The first sensing element 22 of the overflow prevention mechanism 2 and the second sensing element 23 of the other overflow prevention mechanism 2 can effectively perform double overflow prevention.

其工作原理与图5所示实施方式的工作原理相同，此处不再累述。Its working principle is the same as that of the embodiment shown in FIG. 5 , and will not be repeated here.

挡板21还可以以滑动连接的方式设置在排液口11，具体的，挡板21与排液口11在竖直方向上相贴合，储液箱1内设置有中空的限位件，中空的限位件用来装载反应件3，并限制反应件3脱离该限位件。The baffle 21 can also be arranged on the liquid discharge port 11 in a sliding manner. Specifically, the baffle 21 and the liquid discharge port 11 are vertically attached to each other, and the liquid storage tank 1 is provided with a hollow stopper. The hollow stopper is used to load the reaction piece 3 and restrict the reaction piece 3 from leaving the stopper.

反应件3上从限位件上伸出连接部，该连接部的一端与反应件3连接，另一端与挡板21相连接，其中，限位件上设置有沿竖直高度方向设置的条形开口，连接部与该条形开口滑动连接，反应件3上升时，带动连接部相对于条形开口向上滑动，挡板21将排液口11打开，进行排液，并且打开的程度随着高度上升而增加，反应件3下降时，带动连接部相对于条形开口向下滑动，挡板21将排液口11关闭，并且关闭的程度随着高度下降而增加。The reaction piece 3 protrudes from the limiting piece with a connecting portion, one end of the connecting portion is connected with the reaction piece 3, and the other end is connected with the baffle plate 21, wherein the limiting piece is provided with bars arranged along the vertical height direction. When the reaction member 3 rises, it drives the connecting part to slide upward relative to the bar-shaped opening, and the baffle 21 opens the liquid discharge port 11 for liquid discharge, and the degree of opening increases with the The height increases and increases. When the reaction piece 3 descends, the connecting portion is driven to slide downward relative to the strip opening, and the baffle 21 closes the liquid discharge port 11 , and the degree of closure increases as the height decreases.

工作原理：在反应件3上升时，第一种情况，如果进液速度大于排液速度，那么反应件3继续上升至第二高度d2，反应件3上的被感应件24进入第一感应件22的感应范围内，触发第一感应件22发出第一信号，第一控制部接收第一信号，并根据该第一信号输出第一控制信号，以控制电磁阀控制进液通道关闭。此时在反应件3回落时，第一感应件22还可以发出感应到被感应件24脱离感应范围的第四信号，第一控制部能够根据第四信号输出第四控制信号控制电磁阀打开进液通道，打开后如果进液速度大于排液速度，那么反应件3继续上升触发第一感应件22，使得第一控制部输出第一信号控制进液通道阻断，以此往复进行，以最大程度的增加进液，表现在用于清洁拖擦件的基站时，可以尽可能的增加清洁用水，以提高清洁效率。打开后如果进液速度小于排液速度，那么反应件3下降，并带动挡板21最终关闭排液口11。第二种情况，如果进液速度小于排液速度，那么反应件3下降，并带动挡板21活动至反应件3处于第一高度d1，挡板21关闭排液口11。Working principle: When the reaction part 3 rises, in the first case, if the liquid inlet speed is greater than the liquid discharge speed, then the reaction part 3 continues to rise to the second height d2, and the sensed part 24 on the reaction part 3 enters the first induction part Within the sensing range of 22 , the first sensing element 22 is triggered to send out a first signal, and the first control unit receives the first signal and outputs a first control signal according to the first signal to control the solenoid valve to close the liquid inlet channel. At this time, when the reacting member 3 falls back, the first sensing member 22 can also send out a fourth signal that senses that the sensing member 24 is out of the sensing range, and the first control unit can output the fourth control signal according to the fourth signal to control the solenoid valve to open and enter. After the liquid channel is opened, if the liquid inlet speed is greater than the liquid discharge speed, the reaction member 3 continues to rise to trigger the first sensing member 22, so that the first control unit outputs the first signal to control the liquid inlet channel to be blocked, so as to reciprocate and maximize the maximum The degree of increasing the liquid inflow means that when cleaning the base station of the mopping element, the cleaning water can be increased as much as possible to improve the cleaning efficiency. After opening, if the liquid inlet speed is lower than the liquid discharge speed, the reaction member 3 descends and drives the baffle 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 plate 21 to move until the reaction member 3 is at the first height d1, and the baffle plate 21 closes the liquid discharge port 11 .

在上述的实施方式之中，排液口11均可以连通至如地漏等外界直接将液体排出或者可以连通至一个备用的第一储液空间，比如在储液箱1下方或侧方或上方再设置一个储液中转腔；当储液中转腔设置在储液箱1下方或侧方时，还可以在储液中转腔的基础上再设置位于储液箱1上方的第二储液空间，此时，储液中转腔可以设置一条通路连通至第二储液空间，并通过增压泵吸取储液中转腔的液体至第二储液空间，这种结构可以避免排液通道堵塞造成的液体外溢问题，高度较高的排液口11不会被下沉的污物堵塞，通过增压泵可以将第一储液空间的液体转移至第二储液空间，增压泵也可以是排液通道采用的同一增压泵，也可以是另外设置的增压泵。In the above-mentioned embodiments, the liquid discharge port 11 can be connected to the outside world such as a floor drain to directly discharge the liquid, or can be connected to a spare first liquid storage space, for example, under or on the side or above the liquid storage tank 1 . A liquid storage transfer cavity is provided; when the liquid storage transfer cavity is arranged below or on the side of the liquid storage tank 1, a second liquid storage space located above the liquid storage tank 1 can also be set on the basis of the liquid storage transfer cavity. When the liquid storage transfer cavity is connected to the second liquid storage space, a channel can be set to connect to the second liquid storage space, and the liquid in the liquid storage transfer cavity can be sucked into the second liquid storage space through the booster pump. This structure can avoid the liquid overflow caused by the blockage of the liquid discharge channel. The problem is that the liquid discharge port 11 with a higher height will not be blocked by the sinking dirt. The liquid in the first liquid storage space can be transferred to the second liquid storage space through the booster pump, and the booster pump can also be a discharge channel. The same booster pump used may also be an additional booster pump.

在上述的实施方式之外，还可以采用三个以上的防溢机构2进行组合，达到防溢效果更好的液体防溢。In addition to the above-mentioned embodiments, three or more anti-overflow mechanisms 2 can also be used for combination, so as to achieve better anti-overflow effect of liquid overflow prevention.

当然，除了用单个挡板21打开单个排液口11的方式，还存在其他用于排出所述储液箱1的液体，比如两个挡板21打开两个排液口11的方式进行组合，比如通过电磁阀控制排液通道打开的方式，并且可以是两个防溢机构2分别控制一个排液通道打开，或者与挡板21打开排液口11的方式进行组合。Of course, in addition to using a single baffle 21 to open a single liquid discharge port 11, there are other methods for discharging the liquid from the liquid storage tank 1, such as a combination of two baffles 21 opening two liquid discharge ports 11, For example, a solenoid valve is used to control the opening of the liquid discharge channel, and the two overflow prevention mechanisms 2 can respectively control the opening of one liquid discharge channel, or can be combined with the way that the baffle 21 opens the liquid discharge port 11 .

同样的，除了用电磁阀控制停止液体输入所述储液箱1的防溢机构2外，也可以通过电机联动阻隔板，通过电机动作控制阻隔板关闭进液口以停止液体输入。Similarly, in addition to controlling the overflow prevention mechanism 2 of the liquid storage tank 1 to stop the liquid input by the solenoid valve, the blocking plate can also be controlled by the motor to close the liquid inlet to stop the liquid input.

如图11所示，图11是另一变形例的两个防溢机构组合的结构示意图。As shown in FIG. 11 , FIG. 11 is a schematic structural diagram of a combination of two overflow prevention mechanisms in another modification.

图11示出了两个防溢机构2均采用感应件进行触发，竖向高度较低的感应件为第一感应件22，竖向高度较高的感应件为第二感应件23，两个感应件分别和第一控制部电连接，控制部可以根据两个感应件发出的不同信号分别控制不同的排液通道进行通断，当所有所述排液通道打开时，排液速度大于进液速度。FIG. 11 shows that the two overflow prevention mechanisms 2 are triggered by sensing elements. The sensing element with the lower vertical height is the first sensing element 22 , and the sensing element with the higher vertical height is the second sensing element 23 . The induction parts are respectively electrically connected with the first control part, and the control part can respectively control the on-off of different drainage channels according to different signals sent by the two induction parts. When all the drainage channels are opened, the drainage speed is higher than that of the liquid inlet. speed.

工作原理：在液位上升时，反应件3浮动至进入第一感应件22的感应范围，第一感应件22发出第五信号，第一控制部接收第五信号并根据第五信号输出第五控制信号，以控制其中一条排液通道打开，此时，第一种情况，如果进液速度仍然大于排液速度，液位上升，反应件3浮动至进入第二感应件23的感应范围，第二感应件23发出第六信号，第一控制部接收第六信号并根据第六信号输出第六控制信号，以控制所有所述排液通道打开，此时液位下降，由于第二感应件23的位置位于储液箱1的最高液位，因此，反应件3无法上升至超过第二感应件23的感应范围，此时，反应件3随着液位下降而下降，当下降至进入第一感应件22的感应范围时，第一感应件22发出第七信号，第一控制部根据第七信号输出第七控制信号，以将第一感应件22对应控制的排液通道关闭阻断流通，在储液箱1正常出水的情况下，反应件3回落至起点，可以在起始点设置感应件，以控制反应件3回落至起始点时保持所有排液通道关闭阻断流通。第二种情况，如果进液速度小于排液速度时，反应件3回落至起点，同样的，可以在起始点设置感应件，以控制反应件3回落至起始点时保持所有排液通道关闭阻断流通。Working principle: When the liquid level rises, the reaction part 3 floats to enter the sensing range of the first sensing part 22, the first sensing part 22 sends out the fifth signal, and the first control part receives the fifth signal and outputs the fifth signal according to the fifth signal. The control signal is used to control one of the discharge channels to open. At this time, in the first case, if the liquid feed speed is still greater than the discharge speed, the liquid level rises, and the reaction element 3 floats to the sensing range of the second sensing element 23. The second sensing element 23 sends out a sixth signal, and the first control unit receives the sixth signal and outputs the sixth control signal according to the sixth signal, so as to control all the drainage channels to open. The position of the reaction part 3 is located at the highest liquid level of the liquid storage tank 1. Therefore, the reaction part 3 cannot rise beyond the sensing range of the second induction part 23. When the sensing range of the sensing element 22 is reached, the first sensing element 22 sends out a seventh signal, and the first control unit outputs a seventh control signal according to the seventh signal, so as to close the drainage channel controlled by the first sensing element 22 to block the flow. In the case of normal water output from the liquid storage tank 1, the reaction member 3 falls back to the starting point, and a sensing member can be set at the starting point to control the reaction member 3 to fall back to the starting point to keep all drainage channels closed to block flow. In the second case, if the liquid feeding speed is lower than the liquid discharging speed, the reaction element 3 will fall back to the starting point. Similarly, a sensing element can be set at the starting point to control the reaction element 3 to return to the starting point and keep all the drainage channels closed. cut off the flow.
