Description

Technical Field

[0001] This application belongs to the technical field of cleaning equipment. More specifically, it relates to a liquid detection component, a liquid supply device, and a liquid supply system. Background Art

[0002] Intelligent cleaning robots are used to travel on the surface to be cleaned. By using the movement of the cleaning components at the bottom of the main body relative to the surface to be cleaned, the surface to be cleaned can be mopped and vacuumed. There is a clean water tank in the cleaning robot. The cleaning component can be a rotary brush. When the cleaning robot docks at the liquid supply device, the liquid supply device can supply clean water into the clean water tank, and the clean water tank supplies clean water to the rotary brush, and the rotary brush can clean the ground.

[0003] In the prior art, in order for the liquid supply system to detect whether there is liquid in the clean water tank and the current liquid level, so as to ensure that the liquid supply device can normally supply clean water to the cleaning main body, a liquid detection sensing module is arranged inside the box body of the clean water tank, which can be a pole piece type no-liquid detection module or a capacitance detection module.

[0004] Among them, the existing liquid detection sensing module and detection method have the following technical defects:

[0005] First, the existing liquid detection sensing module is detachably installed on the inner side of the box wall of the clean water tank, and its detection signal is obtained through separable detection. The liquid detection sensing module is installed through a detachable structure, resulting in the complication of the entire module structure and high manufacturing and installation costs.

[0006] Second, the clean water tank is detachably installed on the liquid supply device, and the user can remove and reinstall the clean water tank multiple times according to needs. Therefore, the liquid detection sensing module is removed and reinstalled multiple times along with the clean water tank. Under the high-frequency movement and vibration of the clean water tank, the connection reliability of the liquid detection sensing module relative to the box body is reduced. This installation and detection method has high requirements for the seismic performance, anti-fatigue performance, and installation position accuracy of the liquid detection sensing module, resulting in an increase in the installation cost of the liquid detection sensing module and being prone to poor contact and detection failure problems under the high-frequency movement of the clean water tank.

[0007] Third, since the existing liquid detection sensing module is installed on the inner side of the box wall of the clean water tank, the liquid detection sensing module and the clean water tank are taken as a detachable and installable whole, and the user can take and install this whole. Since different cleaning main bodies correspond to different liquid supply devices, and different liquid supply devices are provided with clean water tanks of different specifications, and the liquid detection sensing module needs to be designed differently according to clean water tanks of different specifications and different internal spaces, the liquid detection sensing module cannot be standardized and has poor versatility.

[0008] Fourth, since the existing liquid detection and sensing module is installed on the inner side of the wall of the clean water tank, there is a certain volume of space in the tank in both the height direction and the width direction of the tank body, resulting in a high requirement for the volume of the liquid to be measured by the existing liquid detection and sensing module. If there is still clean water in the tank during the detection, the clean water must reach the set volume before the liquid detection and sensing module can detect the liquid level of the clean water. For example, there is still clean water in the tank, but the water level of the clean water is between two pole pieces. At this time, a water film cannot be formed between the two pole pieces, resulting in the inability to detect the current water level.

[0009] Fifth, since the existing liquid detection and sensing module is installed on the inner side of the wall of the clean water tank, there is a certain volume of space in the tank in both the height direction and the width direction of the tank body, resulting in a high requirement for the volume of the liquid to be measured by the existing liquid detection and sensing module. In this case, the larger volume of the liquid to be measured occupies a large space and contains a relatively large amount of gas. The bubbles formed by the gas are not easy to discharge, resulting in difficulty in forming a reliable water film, reducing the detection accuracy or prone to false alarms. Summary of the Invention

[0010] The purpose of the embodiments of the present application is to provide a liquid detection component, a liquid supply device, and a liquid supply system to solve the technical problems of easy detection failure and poor versatility of the liquid detection method used in the existing liquid supply device.

[0011] To achieve the above object, the technical solution adopted by the present application is:

[0012] Provide a liquid detection component, the liquid detection component includes a body part and two electrode elements;

[0013] The body part has a cavity, and a liquid inlet and a liquid outlet respectively communicating with the cavity;

[0014] The electrode elements are arranged on the body part, one end of the electrode element is placed inside the cavity, and the other end of the electrode element is placed outside the body part; among them, the two electrode elements are a positive electrode element and a negative electrode element respectively.

[0015] In some embodiments, the body part has an axis, the liquid inlet and the liquid outlet are arranged opposite to each other along the axis, and the two electrode elements are arranged at intervals along the axis.

[0016] In some embodiments, the two electrode elements are arranged flush along the axis;

[0017] Or, the two electrode elements are arranged at intervals along the circumferential direction of the body part;

[0018] Among them, the circumferential direction is perpendicular to the axis.

[0019] In some embodiments, the body member is provided with two injection holes, and the two electrode elements are respectively injection-molded in the two injection holes.

[0020] In some embodiments, the body member includes a body and a cover. The body has the cavity, as well as the liquid inlet and the liquid outlet. The cavity has an open end, and the cover is disposed on the open end. The two electrode elements are disposed on the cover.

[0021] In some embodiments, the cover is detachably clamped on the open end and is adhesively bonded to the open end.

[0022] In some embodiments, the spacing distance between the two electrode elements is between 2 mm and 100 mm.

[0023] The beneficial effects of the liquid detection member provided in this application are as follows:

[0024] The liquid detection member provided in this application, wherein the body member has a cavity, as well as a liquid inlet and a liquid outlet that are respectively communicated with the cavity. Therefore, the liquid can enter through the liquid inlet, pass through the cavity, and then flow out through the liquid outlet. Since the body member is provided with a liquid inlet and a liquid outlet, the body member can be configured to be on the path of the liquid supply device supplying water to the cleaning host. The liquid inlet is configured upstream of the water supply path, and the liquid outlet is configured downstream of the water supply path.

[0025] The electrode elements are disposed on the body member. One end of the electrode element is placed inside the cavity, and the other end of the electrode element is placed outside the body member. In this way, when the measured liquid passes through the cavity from the liquid inlet, it will flow through one end of the two electrode elements located inside the cavity. When there is liquid flowing through the water supply path, the two electrode elements are conducted to form a circuit. When there is no liquid flowing through the water supply path, the two electrode elements are disconnected and cannot form a circuit. According to the change in the resistance value in the circuit, it is judged whether there is liquid in the water supply path. The liquid in the water supply path comes from the liquid storage tank, that is, it is judged whether there is liquid in the liquid storage tank.

[0026] Compared with the prior art, the liquid detection member provided in the embodiments of this application has the following technical advantages:

[0027] First, for the liquid detection member provided in the embodiments of this application, the body member has a liquid inlet and a liquid outlet, and it can be configured on the water supply path through the liquid inlet and the liquid outlet. By being configured on the water supply path, it is configured on the liquid supply device. There is no need to additionally design a detachable structure for its assembly, which simplifies the structure of the liquid detection member itself and its installation method, reduces the manufacturing and installation costs, and at the same time simplifies the internal structure of the liquid supply device.

[0028] Second, for the liquid detection component provided in the embodiments of the present application, the main body component thereof has a liquid inlet and a liquid outlet, and it can be arranged on the water supply path through the liquid inlet and the liquid outlet, without being arranged inside the liquid storage tank and being frequently moved and installed together with the liquid storage tank. Except for maintenance and replacement, there is no need to remove and install the liquid detection component. Therefore, the installation and detection methods of the liquid detection component have no requirements for seismic performance, anti-fatigue performance, and the accuracy of the installation position, further reducing its installation cost, and at the same time facilitating the maintenance of good contact of the electrode components in the liquid detection component, thereby ensuring the effectiveness and accuracy of detection.

[0029] Third, for the liquid detection component provided in the embodiments of the present application, the main body component thereof has a liquid inlet and a liquid outlet, and it can be arranged on the water supply path through the liquid inlet and the liquid outlet. By being arranged on the water supply path, it is arranged outside the liquid storage tank. Even if different cleaning hosts correspond to different liquid supply devices, and different liquid supply devices are provided with water tanks of different specifications, the liquid detection component can be configured as a general component on different liquid supply devices, making it universal and capable of being produced separately and standardized.

[0030] Fourth, for the liquid detection component provided in the embodiments of the present application, the main body component has a liquid inlet and a liquid outlet, and it can be arranged on the water supply path through the liquid inlet and the liquid outlet. The flow rate per unit time on the water supply path is very small relative to the liquid storage tank, and the two electrode components can complete the detection through a small flow rate, without high volume requirements for the liquid to be measured.

[0031] Fifth, for the liquid detection component provided in the embodiments of the present application, the main body component has a liquid inlet and a liquid outlet, and it can be arranged on the water supply path through the liquid inlet and the liquid outlet. When the liquid flows through the water supply path, due to the flow state itself, gas can be effectively discharged, and the gas contained in the liquid on the water supply path is small, and bubbles are easily discharged with the flow, easily forming a reliable water film, improving the detection accuracy and not easily causing false alarms.

[0032] Another object of the embodiments of the present application is also to provide a liquid supply device, the liquid supply device includes a liquid storage tank, and the liquid detection component as described above. The liquid detection component is arranged outside the liquid storage tank, and the liquid inlet of the liquid detection component is communicated with the liquid storage tank.

[0033] In some embodiments, the liquid storage tank is a base station water tank; the liquid supply device has a base station clean water docking port, and the base station clean water docking port is used for docking with the host clean water docking port of the cleaning host to provide clean water to the host clean water tank of the cleaning host;

[0034] Wherein, the liquid outlet of the liquid detection component is communicated with the base station clean water docking port.

[0035] In some embodiments, the liquid supply device further includes a water pump connected between the liquid storage tank and the liquid inlet;

[0036] The liquid inlet and the liquid outlet are arranged in sequence from bottom to top along the height direction of the liquid supply device.

[0037] In some embodiments, the liquid supply device further includes a first pipe fitting and a second pipe fitting. The liquid detection member and the water pump are arranged in sequence from bottom to top along the height direction of the liquid supply device;

[0038] The first pipe fitting includes a first pipe portion and a second pipe portion that are integrally and angularly connected. The port of the first pipe portion away from the second pipe portion is connected to the water pump, and the port of the second pipe portion away from the first pipe portion is connected to the liquid inlet; the second pipe fitting is connected between the liquid outlet and the clear water interface of the base station.

[0039] In some embodiments, the connection line between the liquid inlet and the liquid outlet is inclined relative to the horizontal line.

[0040] Compared with the prior art, the liquid supply device provided by the embodiments of the present application has the following technical advantages:

[0041] The liquid supply device provided by the embodiments of the present application adopts the liquid detection member provided by the embodiments of the present application. The body member thereof has a liquid inlet and a liquid outlet, and can be configured on the water supply path through the liquid inlet and the liquid outlet, and is configured on the liquid supply device by being configured on the water supply path. There is no need to separately design a detachable structure for its assembly, which simplifies the structure of the liquid detection member itself and its installation method, reduces the manufacturing and installation costs, and at the same time simplifies the internal structure of the liquid supply device. It does not need to be configured inside the liquid storage tank and is moved and taken on and off with the liquid storage tank at a high frequency. Except for maintenance and replacement, there is no need to remove and install the liquid detection member. Therefore, the installation and detection methods of the liquid detection member have no requirements for seismic performance, anti-fatigue performance, and the accuracy of the installation position, further reducing its installation cost, and at the same time facilitating the maintenance of good contact of the electrode elements in the liquid detection member, thereby ensuring the effectiveness and accuracy of detection.

[0042] At the same time, the liquid detection element can be configured as a general component on different liquid supply devices, making it universal and capable of being produced separately and standardized. The flow rate per unit time on the water supply path is very small relative to the liquid storage tank, and the two electrode elements can complete the detection through a small flow rate, and there is no high volume requirement for the liquid to be measured. When the liquid flows through the water supply path, since the flow state itself can effectively discharge gas, and the gas contained in the liquid on the water supply path is small, the bubbles are easily discharged with the flow, and it is easy to form a reliable water film, improving the detection accuracy and not prone to false alarms.

[0043] Another object of the embodiments of the present application is also to provide a liquid supply system, which includes a cleaning host and the liquid supply device as described above;

[0044] The liquid storage tank is a base station clean water tank. The liquid supply device has a base station clean water connection port. The liquid inlet of the liquid detection member is communicated with the base station clean water tank, and the liquid outlet of the liquid detection member is communicated with the base station clean water connection port;

[0045] The cleaning host has a host clean water tank and is docked with a host clean water connection port communicated with the host clean water tank. When the cleaning host docks on the liquid supply device, the base station clean water connection port is docked with the host clean water connection port to supply clean water to the host clean water tank.

[0046] The beneficial effects of the liquid supply system provided by the embodiments of the present application compared with the prior art are the same as the beneficial effects of the liquid detection member provided by the embodiments of the present application and the liquid supply device provided by the embodiments of the present application compared with the prior art, and will not be elaborated here.

It should be understood that the specific embodiments described herein are only used to explain this application and are not used to limit this application.

[0060] It should be noted that when an element is referred to as "fixed to" or "disposed on" another element, it can be directly on the other element or indirectly on the other element. When an element is referred to as "connected to" another element, it can be directly connected to the other element or indirectly connected to the other element.

It is only for the convenience of describing this application and simplifying the description, rather than indicating or implying that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore cannot be understood as a limitation to this application.

[0062] In addition, the terms "first" and "second" are only used for descriptive purposes and cannot be understood as indicating or implying relative importance or implicitly specifying the quantity of the indicated technical features. Thus, the features defined with "first" and "second" may explicitly or implicitly include one or more of such features. In the description of this application, "a plurality" means two or more, unless otherwise specifically defined.

[0063] Now, the liquid detection member 100, liquid supply device 200 and liquid supply system provided by the embodiments of this application will be described.

[0064] Please refer to Figures 1 to 5As shown in the figure, the liquid detection component 100 provided by the embodiment of the present application includes a body component 101 and two electrode components 102. The body component 101 has a cavity 1011, and a liquid inlet 1012 and a liquid outlet 1013 that are respectively communicated with the cavity 1011. The electrode components 102 are arranged on the body component 101. One end of the electrode component 102 is placed inside the cavity 1011, and the other end of the electrode component 102 is placed outside the body component 101; among them, the two electrode components 102 are a positive electrode component 102 and a negative electrode component 102 respectively. Among them, the electrode component 102 can be an electrode plate.

[0065] For the liquid detection component 100 provided in this embodiment, the body component 101 has a cavity 1011, and a liquid inlet 1012 and a liquid outlet 1013 that are respectively communicated with the cavity 1011. Therefore, the liquid can enter through the liquid inlet 1012, pass through the cavity 1011, and flow out from the liquid outlet 1013. Since the body component 101 is provided with a liquid inlet 1012 and a liquid outlet 1013, the body component 101 can be configured to be arranged on the path of the liquid supply device 200 supplying water to the cleaning host. The liquid inlet 1012 is configured at the upstream of the water supply path, and the liquid outlet 1013 is configured at the downstream of the water supply path.

[0066] The electrode component 102 is arranged on the body component 101. One end of the electrode component 102 is placed inside the cavity 1011, and the other end of the electrode component 102 is placed outside the body component 101. In this way, when the measured liquid passes through the cavity 1011 from the liquid inlet 1012, it will flow through one end of the two electrode components 102 located inside the cavity 1011. When there is liquid flowing through the water supply path, the two electrode components 102 are conducted to form a loop. When there is no liquid flowing through the water supply path, the two electrode components 102 are disconnected and cannot form a loop. Whether there is liquid in the water supply path is judged according to the change of the resistance value in the loop. The liquid in the water supply path comes from the liquid storage tank, that is, whether there is liquid in the liquid storage tank is judged.

[0067] The liquid detection component 100 provided in this embodiment has the following technical advantages:

[0068] First, the body component 101 has a liquid inlet 1012 and a liquid outlet 1013, and it can be configured on the water supply path through the liquid inlet 1012 and the liquid outlet 1013, and configured on the liquid supply device 200 by being configured on the water supply path. There is no need to design a detachable structure for its assembly separately, which simplifies the structure of the liquid detection component 100 itself and its installation method, reduces the manufacturing and installation costs, and simplifies the internal structure of the liquid supply device 200 at the same time.

[0069] Second, the main body 101 has a liquid inlet 1012 and a liquid outlet 1013, and can be arranged on the water supply path through the liquid inlet 1012 and the liquid outlet 1013, without being arranged inside the liquid storage tank and being frequently moved and installed together with the liquid storage tank. Except for maintenance and replacement, there is no need to remove and install the liquid detection component 100. Therefore, the installation and detection methods of the liquid detection component 100 have no requirements for seismic performance, anti-fatigue performance, and the accuracy of the installation position, further reducing its installation cost, and at the same time facilitating the maintenance of good contact of the electrode element 102 in the liquid detection component 100, thereby ensuring the effectiveness and accuracy of detection.

[0070] Third, the main body 101 has a liquid inlet 1012 and a liquid outlet 1013, and can be arranged on the water supply path through the liquid inlet 1012 and the liquid outlet 1013. By being arranged on the water supply path, it is arranged outside the liquid storage tank. Even if different cleaning hosts correspond to different liquid supply devices 200, and different liquid supply devices 200 are provided with water tanks of different specifications, this liquid detection element can be configured as a general component on different liquid supply devices 200, making it universal and allowing for separate standardized production.

[0071] Fourth, the main body 101 has a liquid inlet 1012 and a liquid outlet 1013, and can be arranged on the water supply path through the liquid inlet 1012 and the liquid outlet 1013. The flow rate per unit time on the water supply path is very small relative to the liquid storage tank. The two electrode elements 102 can complete detection through a small flow rate, and there is no high volume requirement for the liquid to be measured.

[0072] Fifth, the main body 101 has a liquid inlet 1012 and a liquid outlet 1013, and can be arranged on the water supply path through the liquid inlet 1012 and the liquid outlet 1013. When the liquid flows through the water supply path, due to the flow state itself, gas can be effectively discharged, and the gas contained in the liquid on the water supply path is small, and bubbles are easily discharged with the flow, easily forming a reliable water film, improving the detection accuracy and not easily causing false alarms.

[0073] Referring to Figure 1 and Figure 2 As shown, in some embodiments, the main body 101 has an axis, the liquid inlet 1012 and the liquid outlet 1013 are arranged opposite to each other along the axis, and the two electrode elements 102 are arranged at intervals along the axis. In this way, when the liquid enters from the liquid inlet 1012 and flows through the cavity 1011, the liquid can conduct the two electrode elements 102 during the flowing process, combining the conduction direction of the electrode elements 102 and the flowing direction of the liquid, improving the timeliness and accuracy of detection.

[0074] In some embodiments, the body member 101 is tubular. An inlet port 1012 and an outlet port 1013 are respectively formed at both axial ends of the body member 101. The body member 101 has a certain axial extension dimension so that the two electrode elements 102 are spaced apart by a certain distance, and a stable and reliable water film for detection is formed between the two electrode elements 102, thereby improving the accuracy of detection.

[0075] In some embodiments, the portions where the inlet port 1012 is located and the portion where the outlet port 1013 is located can axially extend out of the cavity 1011, and the radial dimensions of the portions where the inlet port 1012 is located and the portion where the outlet port 1013 is located can be smaller than the radial dimension of the portion where the cavity 1011 is located. In this way, the portions where the inlet port 1012 is located and the portion where the outlet port 1013 is located can be configured on the water supply path by means of insertion.

[0076] For example, the body member 101 can be made of a plastic part. The plastic part has a certain elasticity. The portions where the inlet port 1012 is located and the portion where the outlet port 1013 is located are inserted into the head of the water pipe by interference fit, which can not only simplify the assembly method but also provide good sealing performance.

[0077] In other embodiments, a convex structure can be provided on one of the portion where the inlet port 1012 is located and the pipe orifice of the water supply path, and a concave structure can be provided on the other of them. The portion where the inlet port 1012 is located is clamped on the pipe orifice of the water supply path of the water supply path through the interference fit of the convex structure and the concave structure, and a colloid is filled in the gap between the two to increase the sealing performance between the two, ensure that the cavity wall of the cavity 1011 has good sealing performance, and prevent the liquid from leaking to other areas of the liquid supply device 200.

[0078] Similarly, a convex structure can be provided on one of the portion where the outlet port 1013 is located and the pipe orifice of the water supply path, and a concave structure can be provided on the other of them. The portion where the outlet port 1013 is located is clamped on the pipe orifice of the water supply path of the water supply path through the interference fit of the convex structure and the concave structure, and a colloid is filled in the gap between the two to increase the sealing performance between the two, ensure that the cavity wall of the cavity 1011 has good sealing performance, and prevent the liquid from leaking to other areas of the liquid supply device 200.

[0079] As Figures 1 to 2 shown, in some embodiments, the two electrode elements 102 are arranged flush along the axis, and the two electrode elements 102 are in the same circumferential position in the circumferential direction, which can further increase the accuracy of detection. As Figure 3As shown, in some other embodiments, the two electrode elements 102 are arranged at intervals along the circumferential direction of the main body member 101. In this way, the orientation of the occupied space of the electrode elements 102 inside the liquid supply device 200 is increased, and the liquid detection member 100 can be flexibly selected according to the space inside the liquid supply device 200. Among them, the above-mentioned circumferential direction is perpendicular to the above-mentioned axis.

[0080] In some embodiments, the main body member 101 is provided with two injection holes, and the two electrode elements 102 are respectively injection-molded in the two injection holes. For example, during the injection molding process of the main body member 101, the already manufactured pole piece element can be placed at the set position of the mold, and the pole piece element is injection-molded on the main body member 101 to increase the sealing performance between the two.

[0081] In some embodiments, the main body member 101 includes a main body 1014 and a cover body 1015. The main body 1014 has a cavity 1011, as well as a liquid inlet 1012 and a liquid outlet 1013. The cavity 1011 has an opening, and the cover body 1015 is covered on the opening, and the two electrode elements 102 are arranged on the cover body 1015. For example, during the injection molding process of the cover body 1015, the already manufactured pole piece element can be placed at the set position of the mold, and the pole piece element is injection-molded on the cover body 1015 to increase the sealing performance between the two, and then the cover body 1015 is hermetically covered on the opening.

[0082] In some embodiments, the cover body 1015 is detachably clamped on the opening, and the cover body 1015 is adhesively bonded to the opening. For example, a convex structure can be provided on one of the edge of the opening of the main body member 101 and the edge of the cover body 1015, and a groove structure can be provided on the other. The cover body 1015 is clamped on the opening through the interference fit of the convex structure and the groove structure, and a colloid is filled in the gap between the two to increase the sealing performance between the two, ensure that the cavity wall of the cavity 1011 has good sealing performance, and prevent liquid from leaking to other areas of the liquid supply device 200.

[0083] In some embodiments, the interval distance a between the two electrode elements 102 is between 2 mm and 100 mm, which can ensure the formation of a reliable water film between the two electrode elements 102, and can minimize the volume of the liquid detection member 100, reducing the occupation of the internal space of the liquid supply device 200. Preferably, the interval distance between the two electrode elements 102 can be 32 mm, while ensuring the formation of a reliable water film between the two electrode elements 102, reducing the axial dimension of the liquid detection member 100.

[0084] Refer to Figure 4 and Figure 5As shown in the figure, another object of the embodiments of the present application is also to provide a liquid supply device 200, which includes a liquid storage tank and the liquid detection member 100 as described above. The liquid detection member 100 is arranged outside the liquid storage tank, and the liquid inlet 1012 of the liquid detection member 100 is communicated with the liquid storage tank.

[0085] The liquid supply device 200 provided in this embodiment adopts the liquid detection member 100 provided in the embodiments of the present application. The main body member 101 therein has a liquid inlet 1012 and a liquid outlet 1013, and it can be arranged on the water supply path through the liquid inlet 1012 and the liquid outlet 1013, and is arranged on the liquid supply device 200 by being arranged on the water supply path. There is no need to separately design a detachable structure for its assembly, which simplifies the structure of the liquid detection member 100 itself and its installation method, reduces the manufacturing and installation costs, and at the same time simplifies the internal structure of the liquid supply device 200. It does not need to be arranged inside the liquid storage tank and is moved and taken and installed frequently with the liquid storage tank. Except for maintenance and replacement, there is no need to remove and install the liquid detection member 100. Therefore, the installation and detection methods of the liquid detection member 100 have no requirements for seismic performance, anti-fatigue performance and the accuracy of the installation position, further reducing its installation cost, and at the same time facilitating the maintenance of good contact of the electrode element 102 in the liquid detection member 100, thereby ensuring the effectiveness and accuracy of detection.

[0086] At the same time, the liquid detection element can be configured as a general component on different liquid supply devices 200, making it universal and capable of being produced separately and standardized. The flow rate per unit time on the water supply path is very small relative to the liquid storage tank, and the two electrode elements 102 can complete the detection through a small flow rate, and there is no high volume requirement for the liquid to be measured. When the liquid flows through the water supply path, since the flow state itself can effectively discharge gas, and the gas contained in the liquid on the water supply path is small, the bubbles are easily discharged with the flow, and a reliable water film is easily formed, improving the detection accuracy and not easily causing false alarms.

[0087] Exemplarily, the liquid supply device 200 can be a cleaning base station for supplying clean water to a cleaning host.

[0088] In some embodiments, the liquid storage tank is the base station clean water tank 201, and the liquid supply device 200 has a base station clean water docking port 202, which is used to dock with the host clean water docking port of the cleaning host to supply clean water to the host clean water tank of the cleaning host. Among them, the liquid outlet 1013 of the liquid detection member 100 is communicated with the base station clean water docking port 202.

[0089] Selecting the liquid storage tank as the base station clean water tank 201 and docking the base station clean water docking port 202 with the host clean water docking port of the cleaning host facilitates detecting whether there is clean water in the base station clean water tank 201 when the liquid supply device 200 supplies clean water to the cleaning host through the liquid detection member 100.

[0090] Of course, the liquid detection member 100 can also be arranged on other water supply paths or liquid collection paths that are not the clean water tank according to the detection requirements. The embodiments of the present application do not elaborate on other water supply paths or liquid collection paths. The liquid detection member 100 provided by the embodiments of the present application can be arranged on any water path that needs to detect the presence or absence of liquid.

[0091] In some embodiments, the liquid supply device 200 further includes a water pump 203 connected between the liquid storage tank and the liquid inlet 1012. The liquid inlet 1012 and the liquid outlet 1013 are arranged in sequence from bottom to top along the height direction of the liquid supply device 200.

[0092] As an example, an installation method of the liquid detection member 100 provided by the embodiments of the present application is provided, with the liquid inlet 1012 located below and the liquid outlet 1013 located above. Driven by the water pump 203, the liquid flows in the direction from bottom to top. The purpose of this installation method is to avoid that when the liquid flows from top to bottom, due to the change in flow rate and the influence of the gravity of the fluid itself, the liquid forms a wire-shaped liquid column in a drawn state, which cannot ensure that the cavity 1011 of the body member 101 is filled with the liquid during the liquid flow, and thus cannot ensure that the two electrode elements 102 are completely immersed in the liquid under various different flow rates. Therefore, the resistance value difference of the circuit system in the two states of having liquid and no liquid does not change significantly or has no obvious change, and the detection function cannot be realized.

[0093] By arranging the liquid inlet 1012 and the liquid outlet 1013 in sequence from bottom to top along the height direction of the liquid supply device 200, and driven by the water pump 203, the influence of the change in flow rate and the gravity of the fluid itself is avoided, so that the cavity 1011 of the body member 101 is filled with the liquid during the liquid flow, and thus it is ensured that the two electrode elements 102 are completely immersed in the liquid. In the two states of having liquid and no liquid, the resistance value difference of the circuit system can have an obvious change, realizing the accurate detection of the presence or absence of liquid.

[0094] Of course, in other embodiments, on the premise that the pressure inside the liquid storage tank is large enough, the water supply speed and water supply flow rate of the water supply path can be increased. In this case, the liquid inlet 1012 and the liquid outlet 1013 can be located at the same horizontal position, or the liquid inlet 1012 and the liquid outlet 1013 can be arranged in sequence from top to bottom along the height direction of the liquid supply device 200.

[0095] In some embodiments, the liquid supply device 200 further includes a first pipe fitting 204 and a second pipe fitting 205. The liquid detection member 100 and the water pump 203 are arranged in sequence from bottom to top along the height direction of the liquid supply device 200. The first pipe fitting 204 includes a first pipe portion 2041 and a second pipe portion 2042 that are integrally and angularly connected. The port of the first pipe portion 2041 away from the second pipe portion 2042 is connected to the water pump 203, and the port of the second pipe portion 2042 away from the first pipe portion 2041 is connected to the liquid inlet 1012. The second pipe fitting 205 is connected between the liquid outlet 1013 and the base station clean water connection port 202.

[0096] Among them, the first pipe portion 2041 and the second pipe portion 2042 are in an L shape. The first pipe portion 2041 extends in the height direction with a length for transitioning the interval gap between the liquid inlet 1012 and the liquid outlet 1013 in the height direction. The second pipe portion 2042 extends in the horizontal direction with a direction for transitioning the interval gap between the liquid inlet 1012 and the liquid outlet 1013 in the horizontal direction. In this way, the liquid pumped out by the water pump 203 located at a higher position can be drained into the cavity 1011 of the body member 101, enabling the electrode element 102 to complete the detection.

[0097] Among them, it should be noted that the water pump 203 provided in the embodiment of the present application can be set at any position on the water supply path, including the section from the liquid outlet 1013 to the base station clean water connection port 202. Since the water pump 203 can provide a certain driving force, the height position of the water pump 203 relative to the liquid detection member 100 can be set arbitrarily.

[0098] In order to improve the stability of the flow rate of the liquid flowing through the cavity 1011 of the body member 101, make more full use of the driving force of the water pump 203, and rationally utilize the internal space of the liquid supply device 200, the water pump 203 is set between the base station clean water tank 201 and the liquid inlet 1012, and the position of the water pump 203 is higher than the liquid detection member 100.

[0099] In some embodiments, the connection line between the liquid inlet 1012 and the liquid outlet 1013 is inclined relative to the horizontal line. For example, the angle α between the connection line between the liquid inlet 1012 and the liquid outlet 1013 and the horizontal line is any angle between 1° and 179°, including the connection line between the liquid inlet 1012 and the liquid outlet 1013 being inclined relative to the horizontal line. This not only ensures that the liquid can fully fill the cavity 1011, but also can easily extract the water film and bubbles, avoiding false recognition. Preferably, the acute angle between the connection line between the liquid inlet 1012 and the liquid outlet 1013 and the horizontal line can be 40°, that is, the obtuse angle between the two can be 140°.

[0100] Another object of the embodiments of the present application is also to provide a liquid supply system, which includes a cleaning host and the liquid supply device 200 as described above. The liquid storage tank is the base station clean water tank 201. The liquid supply device 200 has a base station clean water docking port 202. The liquid inlet 1012 of the liquid detection member 100 is communicated with the base station clean water tank 201, and the liquid outlet 1013 of the liquid detection member 100 is communicated with the base station clean water docking port 202. The cleaning host has a host clean water tank and is docked with a host clean water docking port communicated with the host clean water tank. When the cleaning host docks on the liquid supply device 200, the base station clean water docking port 202 is docked with the host clean water docking port to supply clean water to the host clean water tank.

[0101] The beneficial effects of the liquid supply system provided by the embodiments of the present application compared with the prior art are the same as the beneficial effects of the liquid detection member 100 provided by the embodiments of the present application and the liquid supply device 200 provided by the embodiments of the present application compared with the prior art, which will not be elaborated here.

Any modifications, equivalent replacements, and improvements made within the spirit and principle of the present application shall be included in the protection scope of the present application.
