[0041] Figure 1 shows a schematic structural diagram of an electrode assembly in one or more embodiments of the present application, Figure 2 Schematic diagrams of the structures of electrode assemblies in other embodiments are shown. Figure 1 as well as Figure 2 The present application provides an electrode assembly, which includes a pole 1 and a shell 2, wherein the shell 2 is wrapped around the pole 1, and the shell 2 is provided with two or more exposed parts for exposing the pole 1, and the two or more exposed parts are at different heights to form two or more trigger parts on the pole 1 that are not at the same height.

[0042] The electrode assembly a provided in the present application has a shell 2 wrapped around the pole 1, and the shell 2 is provided with two or more exposed parts for exposing the pole 1. The two or more exposed parts are at different heights to form more than two trigger parts on the pole 1 that are not at the same height, that is, more than two trigger parts can be provided on one electrode assembly a. In this way, one electrode assembly a can be used to replace more than two water level detectors to simplify installation, which has good practicality.

[0043] Combination Figure 1 as well as Figure 2In some embodiments, the triggering part includes a first triggering part 11. The bottom end of the pole 1 extends out of the bottom of the shell 2, and the part of the pole 1 extending out of the bottom of the shell 2 can serve as the first triggering part 11. That is, in some embodiments, the exposed part is arranged at the bottom of the shell 2 to expose the bottom end of the pole 1, and the bottom end of the pole 1 can contact the water in the sewage tank, so that the part of the pole 1 extending out of the bottom end of the shell 2 serves as the first triggering part 11.

[0045] Combination Figure 1 In some embodiments, the two or more first triggering parts 11 are not at the same height to achieve detection of different water levels.

[0046] Now, under the condition that the electrode assembly a has two poles 1 and the two first triggering parts 11 are not at the same height, the structure of the electrode assembly a and the water level detection in the sewage tank b when the electrode assembly a is assembled in the sewage tank b are further described. For the convenience of description, the first triggering part 11 located at the bottom is defined as the first water level triggering part 111, and the first triggering part 11 located at the top is defined as the second water level triggering part 112.

[0047] Combination Figure 1 The housing 2 includes a connection seat 21 and a sleeve 22. The connection seat 21 is connected to the top of the pole 1. The sleeve 22 can be integrally connected to the bottom of the connection seat 21. The sleeve 22 and the pole 1 are correspondingly arranged. The sleeve 22 is sleeved on the corresponding pole 1, and the exposed part is arranged on the sleeve 22. Under the condition of setting two poles 1, the exposed part of the sleeve 22 is arranged at the bottom of the sleeve 22, that is, the bottom ends of the two poles 1 extend out of the bottom of the corresponding sleeve 22 to serve as two first triggering parts 11. The tops of the two sleeves 22 are roughly located in the same plane, and the heights of the bottoms of the two sleeves 22 are different. Correspondingly, the lengths of the two poles 1 are also different, so as to form two first triggering parts 11 of different heights, that is, the first water level triggering part 111 located at the bottom and the second water level triggering part 112 located at the top.

[0048] Combination Figure 1 The electrode assembly a may further include a pole piece 3.

When the sewage tank b cover is assembled on the host, the contact piece will contact and connect with the corresponding contact point of the host.

[0049] In a specific implementation, the portion of the pole piece 3 can be injection molded in the connection seat 21, and the portion of the pole piece 3 located in the connection seat 21 can be provided with a sleeve hole 31 corresponding to the pole 1 (such as Figure 3 As shown), the top of the pole 1 can be interference-fitted into the corresponding sleeve hole 31, and the portion of the pole piece 3 extending out of the connection seat 21 can be adaptively bent according to the installation environment so that the pole piece 3 is L-shaped or V-shaped as a whole.

Figure 1 as well as Figure 4 In some embodiments, the electrode assembly a may further include a seal 4, which is connected to the outer circumferential surface of the connection seat 21 to improve the sealing effect of the electrode assembly a when assembled in the sewage tank b. In specific implementation, a sealing groove 211 may be provided on the outer circumferential surface of the connection seat 21, and the seal 4 may be a sealing ring, which is provided in the corresponding sealing groove 211, and the seal 4 has a portion protruding from the outer circumferential surface of the connection seat 21. When the electrode assembly a is assembled on the box cover 5 of the sewage tank b, the seal 4 is compressed, thereby improving the sealing effect of the electrode assembly a assembled in the sewage tank b.

[0051] Combination Figure 1 In some embodiments, a positioning groove 212 may be further provided on the outer peripheral surface of the connection base 21. When the electrode assembly a is assembled on the box cover 5 of the sewage tank b, a corresponding protrusion is provided on the box cover 5 to be inserted into the positioning groove 212 to improve the reliability of the electrode assembly a being assembled on the box cover 5 of the sewage tank b.

[0052] Combination Figure 1 In some embodiments, the cross section of the connection seat 21 may be oval, and when the electrode assembly a is assembled on the box cover 5 of the sewage tank b, the circular connection seat 21 has an anti-rotation function to improve the reliability of the electrode assembly a being assembled on the box cover 5 of the sewage tank b. In other embodiments, the cross section of the connection seat 21 may also be a square or trapezoidal non-circular shape, which is not limited here.

[0053] Figure 5 Shows that there is Figure 1 The schematic diagram of the structure of the sewage tank of the electrode assembly shown in FIG. Figure 6 Shows Figure 5Schematic diagram of the structure of the box cover. Figure 5 as well as Figure 6 , under the condition of using the above-mentioned electrode assembly a to detect the water level of the sewage tank b, the above-mentioned electrode assembly a is assembled on the box cover 5 of the sewage tank b, and the box cover 5 of the sewage tank b is also provided with a first electrode 6 and a second electrode 7, the first electrode 6 and the second electrode 7 are both connected to the box cover 5, the first electrode 6 has a third triggering part 61, the second electrode 7 has a fourth triggering part 71, the third triggering part 61 is arranged above the fourth triggering part 71, the fourth triggering part 71 cooperates with the first water level triggering part 111, and the third triggering part 61 is used to cooperate with the second water level triggering part 112 to detect the water level of the sewage tank b in different postures, specifically:

[0054] Figure 7 Shows Figure 5 The schematic diagram of water level detection of the sewage tank in a vertical position is shown in FIG. Figure 7 , under the condition that the sewage tank b is at the first target water level, the water in the sewage tank b conducts the fourth trigger unit 71 and the first water level trigger unit 111 to output the first trigger signal to the controller of the host, and the controller that receives the first trigger signal outputs the water level warning information. That is, the fourth trigger unit 71 and the first water level trigger unit 111 cooperate with each other to output the first water full information to remind the user to pay attention to the water level of the water body in the sewage tank b. The device can stop working and send a warning message to the user to clean the sewage tank b. The water level warning information can be sound or light information, which is not limited here. The first target water level can be the water level in the sewage tank b when the body is in an upright position, or when the tilt angle is greater than or equal to 30°.

[0055] In some embodiments, the fourth trigger unit 71 can be located below the first water level trigger unit 111. When the body of the cleaning equipment is twisted, the water in the sewage tank b is twisted accordingly, so that the fourth trigger unit 71 and the first water level trigger unit 111 are connected through the water in the sewage tank b to realize water level detection under the twisted posture of the body.

[0056] Figure 8 Shows Figure 5 The schematic diagram of water level detection of the sewage tank in a tilted posture shown in FIG. Figure 8, when the sewage tank b is at the second target water level, the water in the sewage tank b conducts the third trigger unit 61 and the second water level trigger unit 112 to output a second trigger signal to the controller. The controller that receives the second trigger signal outputs a water full message, the device stops working, and sends a warning message to the user to clean the sewage tank b. The warning message can be a sound or light warning, which is not limited here. The second target water level can be the water level in the sewage tank b when the fuselage is in an inclined posture and the inclination angle can be less than or equal to 30° (including when the fuselage is in a flat state).

[0057] Combination Figure 6 In some embodiments, two electrode assemblies a may be relatively arranged, and the two electrode assemblies a may be symmetrically arranged along the width direction (i.e., the left-right direction) of the box cover 5 with respect to the vertical center line of the box cover 5. Therefore, when the cleaning device is twisted to the left or forward, the fourth trigger part 71 will be connected to the first water level trigger part 111 through the water body, and the third trigger part 61 will be connected to the second water level trigger part 112 through the water body, thereby realizing water level detection when the body is twisted.

[0058] Combination Figure 2 In some other embodiments, the triggering part also includes a second triggering part 12. The pole 1 of the electrode assembly a may be provided with only one, and its bottom end extends out of the sleeve 22 to serve as the first triggering part 11 located below. A water port 221 is provided on the shell 2 (sleeve 22). The water port 221 can serve as an exposed part of the shell 2. The water port 221 can also expose the pole 1 under the condition of sewage passing through to form a triggering part on the pole 1. The triggering part is even the second triggering part 12 located above. The water level detection principle of the electrode assembly a in this embodiment is similar to the above, and will not be repeated here.

[0059] Combination Figure 2 In some other embodiments, the cross section of the connection base 21 of the housing 2 may be circular. In order to improve the reliability of the assembly of the connection base 21 on the box cover 5, one or more cut surfaces 213 may be provided on the outer peripheral surface of the connection base 21 to prevent the connection base 21 from rotating on the box cover 5. In specific implementation, the cut surfaces 213 may be provided on two opposite side surfaces of the connection base 21, and the cut surfaces 213 may be planes.

[0060] In other embodiments, water holes 221 may be opened at different positions of the sleeve 22 to expose two parts of the pole 1 to serve as the first triggering part 11 and the second triggering part 12 located at the bottom, which will not be described in detail here.

[0061] It should be noted that the shell 2 can be made of hydrophobic and oleophobic Teflon or PP material, and its surface is smooth, which can effectively prevent the sewage in the sewage tank b from adhering. In addition, since the sleeve 22 is provided on the electrode for water level detection, it can prevent the water film generated between the electrodes from causing the electrodes to conduct, causing the device to misreport the water level, and has good practicality.

[0062] In the second aspect of the present application, the present application also provides a sewage tank b. Figure 5 The sewage tank b includes a tank body b1 , a tank cover 5 and the electrode assembly a. The tank cover 5 is detachably arranged in the inlet and outlet b1 , and the electrode assembly a is connected to the tank cover 5 .

[0063] The sewage tank b having the above-mentioned electrode assembly a can have more than two triggering parts on one electrode assembly a, so that one electrode assembly a can be used to replace more than two water level detectors to simplify installation and has good practicality.

[0064] In a third aspect of the present application, the present application further provides a cleaning device, the cleaning device comprising the above-mentioned sewage tank b.

[0065] The cleaning device having the above-mentioned sewage tank b can have more than two triggering parts on one electrode component a, so that one electrode component a can be used to replace more than two water level detectors to simplify installation and has good practicality.

[0066] In some embodiments, the cleaning device may be a mopping machine. Of course, it may also be other types of cleaning devices, such as a water suction machine or a sweeping device, etc., which is not limited here.
