[0002] The machine equipment is usually equipped with a detection pipe and a detection element. The detection pipe has an inlet, an outlet and an inner cavity that is connected to both the inlet and the outlet. The detection element is installed in the inner cavity and is used to detect whether there is liquid flowing from the inlet to the outlet in the inner cavity.

[0003] However, when no liquid flows in from the inlet, residual liquid may remain in the inner cavity, causing the detector to detect liquid and issue a liquid presence signal. This liquid presence signal indicates that liquid is flowing in from the inlet, which can lead to false detections by the detector. Therefore, improvements are urgently needed. Summary of the Invention

[0004] The main objective of this invention is to provide a detection component that can prevent false detections of the detection components.

[0005] To achieve the above objectives, the present invention proposes a detection assembly, which includes a detection pipe and a detection element; wherein,

[0006] The detection pipeline has an inlet, an outlet, and an inner cavity. The inner cavity is connected to the inlet and the outlet. The inner wall of the inner cavity is provided with a collection tank.

[0008] In some embodiments of the present invention, the detection element includes a suspended end, which is one end of the detection element close to the liquid collection tank, and there is a gap between the suspended end and the tank wall of the liquid collection tank.

[0009] In some embodiments of the present invention, the diameter of the liquid collection tank is gradually reduced from the end of the liquid collection tank near the detection element to the end of the liquid collection tank away from the detection element.

[0010] In some embodiments of the present invention, the wall of the liquid collection tank includes a first guide surface and a second guide surface, wherein the first guide surface and the second guide surface are arranged at an angle, wherein the first guide surface is the surface of the liquid collection tank wall with the smallest distance from the liquid inlet, and the second guide surface is the surface of the liquid collection tank wall with the smallest distance from the liquid outlet.

[0011] In some embodiments of the present invention, the inner cavity is provided with two mounting holes, the detection element includes a detection circuit and two detection electrodes, one end of each detection electrode is electrically connected to the detection circuit, and the other end of each detection electrode extends through the corresponding mounting hole to the top of the liquid collection tank.

[0012] In some embodiments of the present invention, each of the detection electrodes is provided with a first sealing ring and a second sealing ring on its outer peripheral wall;

[0013] Each first sealing ring and its corresponding second sealing ring are spaced apart, each first sealing ring extends circumferentially along the corresponding detection electrode, and each second sealing ring extends circumferentially along the corresponding detection electrode.

[0014] Both first sealing rings abut against the inner peripheral wall of the detection pipe, and both second sealing rings abut against the outer peripheral wall of the detection pipe.

The inner cavity is connected to both the inlet and outlet, and its inner wall is provided with a collection tank. The detection element is installed on the detection pipe, extending at least partially into the inner cavity and positioned above the collection tank.

[0035] Please see Figure 1 The present invention proposes a detection component 100, which includes a detection pipe 110 and a detection element 120.

[0036] The detection pipeline 110 has an inlet 110a, an outlet 110b, and an inner cavity 110c. The inner cavity 110c is connected to the inlet 110a and the outlet 110b. The inner wall of the inner cavity 110c is provided with a collection tank 110d.

[0037] The detection pipe 110 can have various shapes, including square pipes, round pipes, and other pipe structures; no specific limitation is made here. The inlet 110a and outlet 110b can be located on the same side or different sides of the detection pipe 110. The number of inlets 110a and outlets 110b can be one or more (two or more). Similarly, the number of inner cavities 110c can also be one or more. The inner cavity 110c and inlet 110a can be configured one-to-one or one-to-many. The correspondence between inner cavities 110c and outlets 110b is set with reference to the correspondence between inner cavities 110c and inlets 110a. When there are multiple inner cavities 110c, the number of inlets 110a and outlets 110b corresponding to each inner cavity 110c can be the same or different; no specific limitation is made here.

[0038] There are many ways to form the liquid collection tank 110d. It can be formed by recessing the inner bottom wall of the inner cavity 110c, or it can be formed by connecting two structural components. The inner cavity 110c and the liquid collection tank 110d are respectively set on the two structural components. In this case, the connection between the two structural components can be a fixed connection, such as welding or bonding, or a detachable connection, such as threaded connection or snap-fit ​​connection. No specific limitation is made here.

[0039] The detection element 120 is installed on the detection pipe 110, and the detection element 120 extends at least partially into the inner cavity 110c and is positioned above the liquid collection tank 110d.

[0040] When liquid flows in from the inlet 110a, the detector 120 detects the liquid and issues a liquid presence signal. When no liquid flows in from the inlet 110a, the collection tank 110d collects the residual liquid in the inner cavity 110c, the detector 120 does not detect the liquid, and issues a no-liquid signal to indicate that no liquid is flowing in from the inlet. Alternatively, the detector 120 may be configured to issue only one of the liquid presence or no-liquid signals.

[0041] By way of example and not limitation, the liquid signal and the non-liquid signal may include at least one of the following signal forms: sound, light, text, and image.

[0042] Specifically, the detection element 120 includes a suspended end 120a, which is the end of the detection element 120 closest to the collection tank 110d, with a gap between the suspended end 120a and the tank wall of the collection tank 110d. This configuration effectively ensures that the suspended end 120a will not come into contact with the residual liquid in the collection tank 110d when collecting residual liquid from the inner cavity 110c, thereby effectively improving the detection accuracy of the detection assembly 100.

[0043] By way of example and not limitation, the suspended end 120a of the detection element 120 may be set above the highest point of the opening of the collection tank 110d, or it may be set flush with the highest point of the opening of the collection tank 110d, or it may extend into the collection tank 110d. Figure 1 The diagram shows the case where the suspended end 120a of the detection element 120 is positioned above the opening of the collection tank 110d. The connection method between the detection element 120 and the detection pipe 110 is set as described above for either a fixed connection or a detachable connection, and will not be elaborated further here.

[0044] The number of detection elements 120 and the number of collection tanks 110d can both be one or more. When there are multiple detection elements 120, the number of collection tanks 110d can be one, with multiple detection elements 120 positioned above the same collection tank 110d. Similarly, when there are multiple detection elements 120, the number of collection tanks 110d can also be multiple, with each detection element 120 positioned above its corresponding collection tank 110d. No specific limitation is made here. Furthermore, when there are multiple collection tanks 110d, detection elements 120 can be positioned above some of the collection tanks 110d. For example, there can be two collection tanks 110d, with one collection tank 110d having a detection element 120 positioned above it, while the other collection tank 110d does not have a detection element 120 positioned above it.

[0045] In this application, "multiple" means at least two.

[0046] In some embodiments, the volume of the collection tank 110d is limited. After collecting the residual liquid in the inner cavity 110c, the liquid collected in the collection tank 110d needs to be poured out. At this time, the detection pipe 110 is flipped or tilted so that the collection tank 110d is located above the inner cavity 110c. The residual liquid collected in the collection tank 110d first flows into the inner cavity 110c and then discharges through the outlet 110b of the inner cavity 110c, thus discharging the residual liquid collected in the inner cavity 110c by the collection tank 110d. Obviously, a drain port can also be provided at the bottom of the collection tank 110d, and a valve can be installed at the drain port. Opening the valve can discharge the liquid collected in the collection tank 110d. In addition, the detection pipe 110 can be made of transparent materials, such as transparent silicone or transparent plastic. This arrangement makes it easy to observe the amount of liquid collected in the collection tank 110d. In this case, the detection pipe 110 can be made entirely of transparent materials, or the detection pipe 110 can be made of transparent materials only at the location of the collection tank 110d. No specific limitation is made here.

[0047] Please see Figure 1 To facilitate the collection of residual liquid in the inner cavity 110c by the collection tank 110d, in some embodiments of the present invention, the diameter of the collection tank 110d is gradually decreasing. Specifically, the diameter of the collection tank 110d gradually decreases from the end of the collection tank 110d near the detection element 120 to the end of the collection tank 110d away from the detection element 120. With this configuration, when the liquid stops flowing in from the inlet 110a, the residual liquid in the inner cavity 110c can quickly converge into the collection tank 110d, facilitating the collection of the residual liquid in the inner cavity 110c by the collection tank 110d.

[0048] Please see Figures 1 to 3In some embodiments of the present invention, the wall of the liquid collecting tank 110d includes a first guide surface 111d and a second guide surface 112d. The first guide surface 111d and the second guide surface 112d are arranged at an angle. The first guide surface 111d is the surface of the liquid collecting tank 110d with the smallest distance from the inlet 110a, and the second guide surface 112d is the surface of the liquid collecting tank 110d with the smallest distance from the outlet 110b. That is, the first guide surface 111d is formed at the position with the smallest distance from the inlet 110a in the wall of the liquid collecting tank 110d, and the second guide surface 112d is formed at the position with the smallest distance from the outlet 110b in the wall of the liquid collecting tank 110d, with the first guide surface 111d and the second guide surface 112d arranged at an angle.

[0049] Through the above technical solution, when no liquid flows in from the inlet 110a, the residual liquid in the inner cavity 110c can quickly converge into the collection tank 110d through the two guide surfaces. Furthermore, the arrangement of the first guide surface 111d and the second guide surface 112d can also remove as much residual liquid as possible from the collection tank 110d itself, thereby facilitating the collection of residual liquid from the inner cavity 110c by the collection tank 110d.

[0050] Specifically, the end of the first guide surface 111d that is away from the liquid inlet 110a is connected at an angle to the end of the second guide surface that is away from the liquid outlet 110b. This arrangement makes it easier to remove residual liquid in the collection tank 110d when the liquid stops passing through the detection pipe 110.

[0051] It should be noted that the included angle between the first guide surface 111d and the second guide surface 112d can be an acute angle, such as 45 degrees, 60 degrees, or other angles. Alternatively, the included angle between the two guide surfaces can be a right angle. It can also be an obtuse angle, such as 120 degrees, 130 degrees, or other angles. Preferably, the included angle between the two guide surfaces is an obtuse angle. Compared to acute or right angles between the first guide surface 111d and the second guide surface 112d, an obtuse angle allows for a gentler slope in the bottom wall of the inner cavity 110c, thus enabling the storage of more residual liquid.

[0052] Please see Figures 1 to 3 There are many types of detection elements 120. In some embodiments of the present invention, the inner cavity 110c is provided with two mounting holes (not shown). The detection element 120 includes a detection circuit (not shown) and two detection electrodes 121. One end of each detection electrode 121 is electrically connected to the detection circuit, and the other end of each detection electrode 121 extends through the corresponding mounting hole to the top of the liquid collection tank 110d.

[0053] As an example, and not a limitation, the top portion of the inner cavity 110c forms two mounting holes, through which the detection electrode 121 is inserted and fitted. This arrangement facilitates the installation and removal of the detection electrode 121. Furthermore, the two detection electrodes 121 are spaced apart. The spacing between the two detection electrodes 121 ensures conductivity when both are in contact with the liquid. The smaller the spacing between the two detection electrodes 121, the faster the circuit conduction between them, and the more sensitive the detection circuit. Therefore, in practical applications, the spacing between the two detection electrodes 121 can be minimized, for example, to 1 cm, 1.5 cm, 2 cm, etc., without specific limitations.

[0054] It should be noted that when the detection element 120 includes a detection circuit and two detection electrodes 121, the liquid passing through the detection pipe 100 includes a liquid that is capable of conducting electricity.

[0055] With the above technical solution, when liquid is flowing through the inner cavity 110c, the power supply circuit of the two detection electrodes 121 is turned on so that the detection circuit sends a liquid presence signal; when there is no liquid in the inner cavity 110c, the power supply circuit of the two detection electrodes 121 is turned off so that the detection circuit sends a liquid absence signal.

[0056] In some embodiments, the detection element 120 may include a liquid level sensor, such as an ultrasonic liquid level sensor or a magnetic float liquid level sensor. When no liquid flows in from the inlet, the liquid level sensor detects a liquid level lower than a specified liquid level, and the detection component can send a no-liquid signal. When liquid flows in from the inlet, the liquid level sensor detects a liquid level equal to or higher than a specified liquid level, and the detection component can send a liquid-present signal. The preset liquid level is the height of the bottom wall of the inner cavity 110c, and so on.

[0057] Please see Figure 1Considering that the connection between each detection electrode 121 and its corresponding mounting hole is solely based on the insertion and engagement, there is an assembly gap between each detection electrode 121 and its corresponding mounting hole, resulting in poor sealing. When liquid flows in from the inlet, the liquid in the inner cavity 110c can easily leak out through the assembly gap between each detection electrode 121 and its corresponding mounting hole. Therefore, in order to effectively prevent the liquid in the inner cavity 110c from leaking out through the assembly gap between each detection electrode 121 and its corresponding mounting hole, in some embodiments of the present invention, each detection electrode 121 is provided with a first sealing ring 121' and a second sealing ring 121" on its outer peripheral wall; each first sealing ring 121' and its corresponding second sealing ring 121" are spaced apart, each first sealing ring 121' extends circumferentially along the corresponding detection electrode 121, and each second sealing ring 121" extends circumferentially along the corresponding detection electrode 121; both first sealing rings 121' abut against the inner peripheral wall of the detection pipe 110, and both second sealing rings 121" abut against the outer peripheral wall of the detection pipe 110.

[0058] By way of example and not limitation, each detection electrode 121 is arranged in a columnar shape, and the first sealing ring 121' and the corresponding second sealing ring 121" are spaced apart along the axial direction of the corresponding detection electrode 121.

[0059] By employing the above-mentioned technical solution, and by providing a first sealing ring 121' and a second sealing ring 121' in each detection electrode 121, the two ends of the mounting hole in the axial direction can be sealed, thereby effectively preventing the liquid in the inner cavity 110c from leaking out from the assembly gap between the detection electrode 121 and the corresponding mounting hole.

[0060] In some embodiments, each detection electrode 121 and its corresponding first sealing ring 121' and second sealing ring 121' are manufactured using a secondary injection molding process. Secondary injection molding is a process in which a certain raw material is molded in a mold, the molded part is removed, and then placed into a secondary molding mold to be injected again with the same or another type of raw material. This arrangement enhances the sealing performance at the connection between each detection electrode 121 and its corresponding two sealing rings 121'.

[0061] In some embodiments, each detection electrode 121 and the corresponding two sealing rings 121' can also be interference fit, and each detection electrode 121 and the corresponding two sealing rings 121' can also be fixed by welding, bonding or other fixing methods.

[0062] Please see Figures 1 to 3In some embodiments of the present invention, when no liquid flows in from the inlet, in order to sterilize the liquid, the detection electrode 121 is covered with a sterilizing coating (not shown) to sterilize the liquid passing through the inner cavity 110c. This arrangement not only sterilizes the liquid passing through the inner cavity 110c through the sterilizing coating, but also effectively prevents corrosion of the detection electrode 121, extending its service life.

[0063] There are many types of antibacterial coatings. One type is silver plating. The antibacterial principle of silver plating is that silver ions have an extremely high reduction potential and are the most potent bactericidal metal ions in nature. Just two parts per billion of silver ions per liter of liquid can kill most bacteria. After the bacteria are killed by silver ions, the silver ions are released from the dead bacterial cells and come into contact with other colonies, repeating the process. This is why silver has such a long-lasting antibacterial effect. Another type is copper plating. Copper ions have a strong inhibitory and bactericidal effect on autotrophic bacteria, killing bacteria such as E. coli and dysentery bacteria in the liquid, especially preventing green algae contamination and the spread of athlete's foot through floors. Other metal platings are also possible, but they will not be listed here.

[0064] Please see Figure 1 and Figure 2 To facilitate the disassembly and assembly of the detection component 120, in some embodiments of the present invention, the inner cavity 110c is provided with a through mounting port 110e. The mounting port 110e includes a first segment 110e' and a second segment 110e' communicating with the first segment 110e'. The diameter of the first segment 110e' is larger than the diameter of the second segment 110e'. The end of the second segment 110e' away from the first segment 110e' is connected to the inner cavity 110c. The detection assembly 100 also includes a mounting plate 130, which cooperates with the first segment 110e', and the detection component 120 is mounted on the mounting plate 130.

[0065] By way of example and not limitation, the mounting plate 130 is square in shape, and the mounting opening 110e is adapted to fit the mounting plate 130. This arrangement facilitates the processing and molding of the mounting plate 130 and the mounting opening 110e.

[0066] With the above technical solution, when installing the test piece 120, first install the test piece 120 onto the mounting plate 130, then snap the mounting plate 130 into the first section 110e', thus simultaneously installing the test piece 120 into the test pipe 110. When disassembling the test piece 120, first pry the mounting plate 130 out from the first section 110e', then remove the test piece 120 from the mounting plate 130, thus completing the disassembly of the test piece 120. This design facilitates the installation and removal of the test piece 120.

[0067] Please see Figure 1To enhance the sealing performance at the connection between the first segment 110e' and the second segment 110e'", in some embodiments of the present invention, a sealing groove (not shown) extending circumferentially along the first segment 110e' is provided at the connection between the first segment 110e' and the second segment 110e'; the mounting plate 130 is provided with a sealing ring 131 that mates with the sealing groove. With this arrangement, the sealing performance at the connection between the mounting plate 130 and the first segment 110e' and the second segment 110e' is enhanced by the cooperation between the sealing groove and the sealing ring 131.

[0068] In some embodiments, the sealing ring 131 and the mounting plate 130 are integrally formed. This configuration can enhance both the sealing strength between the sealing ring 131 and the sealing groove and the connection strength between the sealing ring 131 and the mounting plate 130.

[0069] In some embodiments, in order to further enhance the sealing effect when the sealing ring 131 and the sealing groove are engaged, the difference between the outer diameter and the inner diameter of the sealing ring 131 is the width of the sealing ring 131. The width of the sealing ring 131 is gradually reduced from one end of the sealing ring 131 near the mounting plate 130 to the other end of the sealing ring 131 away from the mounting plate 130. The sealing groove is adapted to the sealing ring 131. This configuration can further enhance the sealing effect when the sealing ring 131 and the sealing groove are engaged.

[0070] Please see Figures 2 to 4 Considering that the detection pipe 110 needs to be installed on the machine equipment 1000 in practical applications, in order to facilitate the installation of the detection pipe 110 on the machine equipment 1000, in some embodiments of the present invention, both sides of the detection pipe 110 that are arranged opposite to each other are provided with snap-fit ​​blocks 111; both sides of the detection pipe 110 that are arranged opposite to each other are provided with guide blocks 112. In addition, the detection pipe 110 may also be provided with only one of the snap-fit ​​blocks 111 and guide blocks 112.

[0071] In some embodiments, the machine body 200 of the machine device 1000 is provided with two parallel snap-fit ​​plates 210. Each snap-fit ​​plate 210 has a snap-fit ​​interface 210a extending through it, which engages with a corresponding snap-fit ​​block 111. The two snap-fit ​​plates 210 are also provided with guide channels 210b extending in a direction close to or away from the machine body 200. The side of each guide channel 210b away from the machine body 200 is provided as an inlet, and each guide channel 210b engages with a corresponding guide block 112. Furthermore, the snap-fit ​​block 111 is made of a material with a certain degree of elasticity, such as plastic or silicone, to ensure that the snap-fit ​​block 111 can be removed from the corresponding snap-fit ​​interface 210a. Additionally, the machine body 200 has a groove 200a located between the two snap-fit ​​plates 210, with the portions of the two detection electrodes 121 located outside the inner cavity 110c located within the groove 200a.

[0072] With the above technical solution, when installing the detection pipe 110 onto the machine body 200, firstly, insert the two guide blocks 112 into the corresponding guide channels 210b. Then, push the detection pipe 110 towards the machine body 200 until each snap-fit ​​block 111 snaps into the corresponding snap-fit ​​interface 210a, thus completing the installation of the detection pipe 110. When removing the detection pipe 110 from the machine body 200, firstly, press each snap-fit ​​block 111 out of the corresponding snap-fit ​​interface 210a. Then, move the detection pipe 110 away from the machine body 200 until each guide block 112 exits the corresponding guide channel 210b, thus completing the disassembly of the detection pipe 110. This design makes the installation and disassembly of the detection pipe 110 convenient.

[0073] In some embodiments, the detection pipe 110 can also be fixed to the machine equipment 1000 by other fixing methods such as threaded connection or magnetic connection.

[0074] Please see Figure 5 and Figure 6 In some embodiments of the present invention, the detection pipe 110 has an inlet connector 113 at the inlet 110a and an outlet connector 114 at the outlet 110b. The detection assembly 100 also includes an inlet pipe 140 and an outlet pipe 150, with the inlet pipe 140 plugged into the inlet connector 113 and the outlet pipe 150 plugged into the outlet connector 114. This arrangement facilitates both the connection of the detection pipe 110 to the liquid source and the discharge of liquid from the detection pipe 110.

[0075] Specifically, each end of the extension direction of the two snap-fit ​​plates 210 adjacent to each other is provided with a snap-fit ​​block 211. The two snap-fit ​​blocks 211 of one snap-fit ​​plate 210 and the two snap-fit ​​blocks 211 of the other snap-fit ​​plate 210 respectively clamp the inlet pipe 140 and the outlet pipe 150. This arrangement facilitates the fixation of the inlet pipe 140 and the outlet pipe 150. Furthermore, the two ends of the detection pipe 110 in the extension direction are clamped and confined between the two snap-fit ​​blocks 211 on each snap-fit ​​plate 210. This arrangement enhances the fixation strength of the detection pipe 110.

[0076] It should be noted that in actual application, the inlet pipe 140 and the outlet pipe 150 are installed to the machine body 200 in a fixed connection or a detachable connection as described in the above embodiments, which will not be elaborated here.

[0077] Please see Figure 5 and Figure 6In some embodiments of the present invention, the diameter of the detection pipe 110 is larger than the diameter of the inlet pipe 140, or / and the diameter of the detection pipe 110 is larger than the diameter of the outlet pipe 150. This configuration can reduce the size of the detection component 100 while ensuring accurate determination of whether liquid has passed through the inner cavity 110c by the two detection electrodes 121.

[0078] As an example and not a limitation, the diameter of the inlet pipe 140 is the same as the diameter of the outlet pipe 150, and the diameter of the detection pipe 110 is 1.3 times, 1.4 times, 1.5 times, 1.6 times, 1.7 times, etc., the diameter of the inlet pipe 140.

[0079] Please see Figure 3 The present invention also proposes a machine device 1000, which includes the detection component 100 as described above and a machine body 200, wherein the detection component 100 is mounted on the machine body 200. The machine body 200 provides a mounting position for the detection component 100.

[0080] By way of example and not limitation, the machine device 1000 may be a cleaning robot or a cleaning base station. The cleaning robot is a robot used for cleaning objects, and the cleaning base station is a device used for maintaining the robot. For example, the cleaning robot may be a sweeping robot or a mopping robot, and the cleaning base station performs at least one of the following functions: cleaning the robot's mopping parts and adding liquid to the liquid storage device in the robot.

[0081] In some embodiments, the detection component 100 can be used to determine whether liquid is stored in the liquid storage device (not shown) of the machine equipment 1000. For example, the inlet 110a of the detection pipe 110 is connected to the liquid storage device. This configuration allows the presence of liquid in the liquid storage device when the detection element 120 detects liquid, and the absence of liquid in the liquid storage device when the detection element 120 does not detect liquid.

[0082] The liquid storage device is a device for storing liquids; for example, the liquid storage device includes a tank for storing liquids.

[0083] The specific structure of the detection component 100 is as described in the above embodiments. Since the machine equipment 1000 adopts all the technical solutions of all the above embodiments, it has at least all the beneficial effects brought about by the technical solutions of the above embodiments, which will not be described in detail here.
