It is to be understood that the data so used may be interchanged, as appropriate, such that embodiments of the present application may be implemented in sequences other than those illustrated or described herein, and that the objects identified by "first," "second," etc. are generally of a type and not limited to the number of objects, e.g., the first object may be one or more. Furthermore, in the description and claims, "and/or" means at least one of the connected objects, and the character "/", generally means that the associated object is an "or" relationship.

The embodiments of the present application will be described in detail below with reference to the accompanying drawings by means of specific embodiments and application scenarios thereof.

Referring to fig. 1 to 5, the embodiment of the present application discloses a fluid detection module 100 that can be used to detect whether a fluid flows through, and when the fluid detection module 100 can be applied to a cleaning base station, it can detect whether the cleaning agent in the cleaning agent container of the cleaning base station is used up, thereby ensuring the normal replenishment of the cleaning agent in the cleaning robot. Of course, the fluid detection module 100 may also be applied to other scenarios, as embodiments of the present application are not specifically limited in this regard.

The disclosed fluid detection module 100 includes a base 110, a substrate 120, and a detection element 130, wherein the base 110 is a base member that can provide a set basis for the substrate 120, the flow channel 113, and the like, and in some embodiments, the base 110 is provided with an inlet 111, an outlet 112, and the flow channel 113, and the inlet 111, the flow channel 113, and the outlet 112 are in communication in sequence, such that fluid can flow into the flow channel 113 via the inlet 111, be channeled via the flow channel 113, and be discharged from the outlet 112.

The substrate 120 is disposed on the base 110, and illustratively, the substrate 120 may be fixed on the base 110, for example, by welding, riveting, bonding, etc. to ensure the firmness and stability between the substrate 120 and the base 110; of course, the substrate 120 may be detachably disposed on the base 110, so as to facilitate disassembly and assembly, and maintenance of components.

The detecting element 130 is configured to detect whether the fluid flows through the flow channel 113, and is disposed on a side of the substrate 120 facing the flow channel 113, so that the fluid can be detected by the detecting element 130 when the fluid flows through the flow channel 113. Illustratively, the detection element 130 may be a component such as a capacitive sensor.

It should be noted that, when the fluid flows through the flow channel 113, the parameter value detected by the detecting element 130 changes, and, for example, the capacitance value detected by the capacitance sensor changes, so as to determine whether the fluid flows through the flow channel 113.

Alternatively, the detecting element 130 may be mounted to the base plate 120 by means of bonding, welding, riveting, clamping, screwing, etc. to ensure the stability and firmness of the mounting, and in some cases, the detecting element 130 may be detached to facilitate maintenance or replacement of the detecting element 130.

Further, the flow channel 113 may have a planar wall 1131 and an arc wall 1132, wherein the planar wall 1131 is disposed close to the substrate 120 and opposite to the detection plane of the detection element 130, and the concave surface of the arc wall 1132 is disposed toward the substrate 120. In some embodiments, the substrate 120 is located above the flow channel 113, and accordingly, the detecting element 130 is located above the flow channel 113, at this time, the planar wall 1131 is a top wall of the flow channel 113, the cambered surface wall 1132 is located below the planar wall 1131, and two ends of the cambered surface wall 1132 are connected to two ends of the planar wall 1131, so as to enclose the flow channel 113 for delivering the fluid. Illustratively, the cambered surface wall 1132 may be a circular arc surface wall, and of course, may also be a non-circular arc surface wall, which is not particularly limited in the embodiment of the present application.

Based on the above arrangement, the cross section of the flow channel 113 may be non-circular, specifically may be a semicircle, a few semicircle, a multi-semicircle, a portal shape, etc., and compared with the flow channel 113 with a circular cross section, the flow channel 113 of this form may increase the effective detection area of the plane wall 1131 covering the detection plane to a certain extent, thereby effectively increasing the lateral detection range of the fluid, improving the detection precision and accuracy, and further effectively alleviating the problem of erroneous judgment caused by the low detection precision of the detection element 130 on the fluid.

It should be noted that, in the related art, the most point of the flow channel with a circular cross section is the position closest to the detection module, and the rest positions are gradually far away from the detection module relative to the most point, so that the area of the flow channel with a circular cross section covering the effective detection part is relatively smaller; in this embodiment of the present application, the cross-sectional shape of the flow channel 113 is designed to be non-circular, especially, one side close to the detecting element 130 is designed to be a plane (i.e., a plane wall), so that the characteristic of wide transverse dimension of the plane is fully utilized, at this time, the nearest part of the flow channel 113 to the detecting element 130 is the plane wall 1131, so that the effective detecting area covering the detecting element 130 is larger, and therefore, for the detecting element 130, the signal detected by the flow channel with the cross-section being the upper flat-lower circular flow channel is more uniform and stable relative to the signal detected by the flow channel with the circular cross-section, and the jitter is less, so as to improve the detecting precision.

In some embodiments, the flow channel 113 further has a first side wall 1133 and a second side wall 1134, and the first side wall 1133 and the second side wall 1134 respectively extend along a direction away from the substrate 120, wherein the first side wall 1133 is connected between one end of the planar wall 1131 and one end of the cambered surface wall 1132, the second side wall 1134 is connected between the other end of the planar wall 1131 and the other end of the cambered surface wall 1132, and the first side wall 1133 and the second side wall 1134 are disposed in parallel. Based on this, the planar wall 1131, the first side wall 1133, the cambered surface wall 1132 and the second side wall 1134 are connected end to form the runner 113 with a gate-shaped outline, in this case, the runner 113 is in a shape of a plane on the upper side, a cambered surface on the lower side, and two sides of the runner are plane, when the fluid flows through the runner 113, the effective detection area of the planar wall 1131 covering the detection plane can be increased to a certain extent, so that the transverse detection range is increased, and the detection precision and accuracy are further improved, so as to accurately judge whether the fluid in the fluid container is used up.

Of course, in other embodiments, the first side wall 1133 and the second side wall 1134 may not be parallel, and specifically, the distance between the respective upper portions of the first side wall 1133 and the second side wall 1134 is greater than the distance between the respective lower portions of the first side wall 1133 and the second side wall 1134, so that the cross section of the flow channel 113 is in a shape with a large top and a small bottom.

Considering that when the fluid storage in the container is small, the flow rate of the fluid in the flow channel 113 is small, at this time, although a small amount of fluid flows on the side of the flow channel 113 away from the detecting element 130, the detecting element 130 cannot easily detect the portion of fluid, so that it is misjudged that there is no fluid in the flow channel 113, and thus it is judged that there is no fluid in the container, however, in reality, there is still a small amount of fluid in the container, and thus fluid waste is easily caused.

Based on the above, in the embodiment of the present application, the arc surface wall 1132 is provided with a plurality of groups of protruding structures 114, and the plurality of groups of protruding structures 114 are disposed at intervals along the extending direction of the flow channel 113. Based on this, when the flow rate of the fluid in the flow channel 113 is smaller, the fluid flows through the top end surface of the protrusion structure 114, so that the fluid is closer to the detecting element 130, so that the fluid in the flow channel 113 is more easily perceived by the detecting element 130, and therefore, the detection accuracy can be improved, so as to alleviate the problem of fluid waste caused by misjudgment of the detecting element 130.

Wherein, each set of the protrusion structures 114 may include a plurality of protrusion structures 114, and the plurality of protrusion structures 114 are arranged along a circumferential direction of the arc wall 1132. It should be noted here that the plurality of protruding structures 114 in each group may be arranged according to a certain rule, or may be arranged randomly, and may be specifically set according to an actual working condition.

In addition, there is a difference in protrusion height of at least some of the plurality of protrusion structures 114 in each set. Specifically, the protrusion heights of the plurality of protrusion structures 114 in each group may be different, and of course, the protrusion heights of one portion may be the same, and the protrusion heights of the other portion may be different. In addition, the protrusion heights of two adjacent sets of protrusion structures 114 may be the same or different. In summary, the protrusion height of each of the protrusion structures 114 is not limited as long as it can flow over the top surface of the protrusion structure 114 even when the flow rate of the fluid in the flow passage 113 is small.

The protrusion structure 114 may be a cylindrical protrusion, a spherical protrusion, a prismatic protrusion, etc., and its specific shape is not limited.

In order to provide the flow channel 113 and realize the installation of the substrate 120, the base 110 may be provided with a receiving cavity 115, the flow channel 113 is disposed on a bottom wall of the receiving cavity 115, the inlet 111 is disposed on one side wall of the receiving cavity 115, the outlet 112 is disposed on the other side wall of the receiving cavity 115, and the substrate 120 is detachably disposed in the receiving cavity 115. In this way, the accommodating chamber 115 can accommodate the components such as the flow channel 113 and the substrate 120, and the flow channel 113 can be covered by the substrate 120, and at the same time, the detection element 130 is located on the side of the substrate 120 facing the flow channel 113, and the detection element 130 can be covered by the substrate 120, so that the components such as the detection element 130 and the flow channel 113 can be protected by the substrate 120 to prevent interference of external factors, and of course, the overall aesthetic appearance of the fluid detection module 100 can be improved to some extent.

In addition, the substrate 120 is detachable with respect to the base 110, so that on one hand, cleaning of the flow channel 113 is facilitated to prevent the flow channel 113 from being blocked, and on the other hand, maintenance or replacement of the detecting element 130 is facilitated.

Further, the base 110 may be provided with a screw hole, the base plate 120 may be provided with a through hole provided corresponding to the screw hole, and accordingly, the fluid detection module 100 may further include a screw fastener 140 penetrating the through hole and screw-coupled with the screw hole. Based on this, the substrate 120 can be easily detached and assembled, and the flow channel 113 can be easily cleaned, so that the flow channel 113 is prevented from being blocked, and the detection element 130 can be easily maintained or replaced.

In other embodiments, the substrate 120 may be detachably mounted to the base 110 by a clamping manner, specifically, two side walls of the accommodating cavity 115 are respectively provided with an elastic clamping protrusion, when the substrate 120 is mounted to the accommodating cavity 115, the substrate 120 may be clamped and limited by the elastic clamping protrusions, so that the substrate 120 is prevented from being separated from the base 110, and when the substrate needs to be detached, an acting force may be manually applied to the elastic clamping protrusions, so that the elastic clamping protrusions are elastically deformed to release the clamping and limiting of the substrate 120, and the substrate 120 may be removed.

In addition, the clean water replenishing assembly 200 may further include a water pump, through which clean water in the water tank may be pumped into the first transfer duct 210 and transferred to the cleaning robot through the first transfer duct 210, to thereby replenish the cleaning robot with clean water.

The detergent supplementary assembly 300 includes a second transfer duct 310, and the second transfer duct 310 is connected to the first transfer duct 210 through a tee 400, and the detergent can be transferred into the first transfer duct 210 through the second transfer duct 310 and the tee 400 to mix the detergent with the clean water and transfer the mixed clean water to the cleaning robot.

In some embodiments, the angle between the axis of the junction of first delivery conduit 210 and tee 400 and the axis of the junction of second delivery conduit to tee 400 is no more than 30 °, so that clear water may be effectively prevented from flowing back through second delivery conduit 310.

The fluid detection module 100 is disposed in the second conveying pipeline 310 to detect whether the cleaning agent flows through the second conveying pipeline 310, so as to determine whether the cleaning agent in the cleaning agent container is used up.

In some embodiments, the cleaning station may further comprise a cleaner container (not shown) and a peristaltic pump 500, wherein the inlet 111 end of the peristaltic pump 500 is connected to the cleaner container and the outlet 112 end of the peristaltic pump 500 is connected to the second delivery conduit 310.
