[0060] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0061] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0062] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0063] In all the examples shown and discussed herein, any specific values ​​should be interpreted as merely exemplary and not as limitations. Therefore, other examples of exemplary embodiments may have different values.

[0064] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0065] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0066] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0067] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0068] This disclosure provides a cleaning device, including a body, a container for storing a solution, a detection device, and a detection channel connecting the container and the detection device. The container has a first opening, and one end of the detection channel communicates with the first opening of the container, while the other end communicates with the detection device. The detection channel includes a pressure-receiving zone adjacent to the detection device. Liquid in the container can flow into the detection channel from the first opening. The liquid entering the detection channel is configured to act on the pressure-receiving zone of the detection channel, causing a pressure change in the pressure-receiving zone. The detection device is configured to detect the pressure in the pressure-receiving zone. When the volume of the liquid in the container changes, the liquid pressure also changes accordingly. Based on the pressure change detected by the detection device, the water level in the container can be determined.

[0069] The detection device can monitor the pressure zone in real time, thereby detecting the pressure of the liquid in the container. The liquid in the container is usually tap water, cleaning fluid, etc., which contains impurities or is corrosive. The pressure zone in the detection channel can separate the liquid inlet area from the detection device, preventing the liquid in the container from directly contacting the detection device. The detection device is isolated from the liquid in the container, thus avoiding the adverse effects of impurities in the liquid on the detection device.

[0070] The cleaning equipment disclosed herein can be a floor scrubber, a cleaning robot, etc. The liquid stored in the container can be water, detergent, etc., and can be used to clean the work surface during the cleaning process.

[0071] In some embodiments of this disclosure, such as Figure 1 , Figure 2As shown, container 2 is mounted on body 1. Container 2 can be configured as a regular structure such as a square or cylindrical shape, or as an irregular structure; this disclosure does not impose any limitations on this. The first opening 21 of container 2 can be located at the bottom of container 2 or on the side wall of container 2. The detection channel 4 has one end connected to container 2 as its first end and the other end connected to detection device 3 as its second end. Liquid in container 2 can enter the inlet area through the first end of detection channel 4 and compress the pressure zone in detection channel 4, transmitting the liquid pressure to the pressure zone. Detection device 3 detects the pressure in the pressure zone to characterize the usage status of the liquid in container 2. When the water level of the liquid in container 2 changes, the pressure transmitted from the inlet area to the pressure zone changes. Detection device 3 can detect the pressure change in the pressure zone in real time, thereby obtaining the pressure change of the liquid in container 2 in real time.

[0072] In some embodiments of this disclosure, the detection device 3 may employ a MEMS (Micro-Electro-Mechanical Systems) pressure sensor. A MEMS pressure sensor is a thin-film element that deforms under pressure. This deformation can be measured using resistance or by sensing changes in the distance between two diaphragms using capacitance, thus outputting a changing electrical signal with high measurement accuracy. The thin film of the MEMS pressure sensor can sense pressure changes in the pressure zone of the detection channel 4, thereby achieving the purpose of pressure detection.

[0073] When the membrane of a MEMS pressure sensor comes into contact with a liquid, the presence of solid impurities or air bubbles in the liquid can affect the deformation of the membrane, leading to inaccurate detection results. In this disclosure, the membrane of the MEMS pressure sensor does not come into contact with the liquid, resulting in more accurate detection results.

[0074] In some embodiments of this disclosure, the detection channel 4 and the first opening 21 of the container 2 can be configured as an integral connection structure, the container 2 is a cavity disposed in the body 1, the detection channel 4 is a channel disposed in the body 1, and the detection device 3 is fixedly connected to the body 1.

[0075] In some embodiments of this disclosure, the body 1 and container 2 are configured as a detachable connection structure. The body 1 has an installation cavity 10, into which the container 2 can be installed. A detection channel 4 is located on the body 1, and after the container 2 is installed in the installation cavity 10, it communicates with the detection channel 4. The detection device 3 and the detection channel 4 can both be located inside the body 1. To ensure the sealing of the container 2, a valve body can be installed in the first opening 21. The valve body can open after being installed in the installation cavity 10, communicating with the detection channel 4, and close after being removed from the installation cavity 10 to prevent leakage. For example, a spring valve can be installed in the first opening 21 of the container 2. The detection channel 4 has a mating interface, and a top post that mates with the spring valve is located at the mating interface. After the container 2 is installed in the installation cavity 10 of the body 1, the first opening 21 mates with the mating interface, and the top post can open the spring valve, allowing the container 2 to communicate with the detection channel 4. Furthermore, the first opening 21 of the container 2 and the detection device 3 are respectively sealed and connected to the first and second ends of the detection channel 4 to prevent liquid leakage. The detection channel 4 can be a channel located inside the body 1, or it can be a pipe connected to the body 1. The detection channel 4 can be a one-piece structure, or it can be formed by sealing and connecting multiple parts such as channels and pipes.

[0076] Example 1

[0077] In one embodiment of this disclosure, reference is made to Figure 3 , Figure 4 , Figure 5 A diaphragm 5 can be installed in the detection channel 4, which can separate the liquid inlet area and the pressure zone in the detection channel 4. The diaphragm 5 forms a sealed cavity 40 in the detection channel 4 to prevent liquid from the liquid inlet area from entering the pressure zone and to prevent liquid from contacting the detection device 3.

[0078] The diaphragm 5 is made of a flexible material with a certain degree of deformation capability, and neither liquid nor gas can pass through it. The material of the diaphragm 5 includes, but is not limited to, rubber and plastic. To improve the detection accuracy of the MEMS pressure sensor and facilitate sensor calibration, the sealed cavity 40 is preferably configured as a vacuum cavity. The liquid entering the detection channel 4 is configured to deform the diaphragm 5, causing a pressure change within the sealed cavity 40. The detection device 3 is configured to detect this pressure change within the sealed cavity 40. The detection device 3 can be in communication with the sealed cavity 40, or it can be at least partially disposed within the sealed cavity 40.

[0079] In one embodiment of this disclosure, the pressure-bearing area of ​​the detection channel 4 can be filled with water, oil, soft rubber, or other media that can change shape after being pressurized. The media contacts the detection device 3, as long as it does not adversely affect the detection device 3. The detection device 3 is used to detect the pressure of the media in the sealing cavity 40. The media in the pressure-bearing area can directly contact the liquid in the inlet area, or the media can be placed in the sealing cavity 40 by setting a diaphragm 5 in the detection channel 4 to separate the media from the liquid in the inlet area. In one embodiment of this disclosure, the volume and pressure in the sealing cavity 40 can also be changed by moving the diaphragm 5. In this embodiment, the diaphragm 5 needs to be set in a way that is entirely movable, such as a piston-like structure. When the external pressure is too high, it will push the diaphragm 5 to move, making the volume of the sealing cavity 40 smaller, thereby increasing the pressure in the sealing cavity 40. This will not be described in detail here.

[0080] In one embodiment of this disclosure, reference is made to Figure 3 , Figure 4 The container 2 and the detection channel 4 are configured as a detachable connection structure. The body 1 is equipped with a first pipe 41 and a mounting base 42. The first pipe 41 is constructed such that one end is connected to the first opening 21 of the container 2, and the other end is sealed to the mounting base 42, forming the detection channel 4. The first pipe 41 can be connected to the body 1 by means of screws, welding, or snap-fit ​​connections, and the mounting base 42 can be connected to the first pipe 41 by means of screws, welding, or snap-fit ​​connections. Furthermore, the first pipe 41 and the first opening 21 of the container 2, as well as the first pipe 41 and the mounting base 42, can be sealed together by a sealing structure.

[0081] In one specific embodiment of this disclosure, the first opening 21 is disposed at the bottom of the container 2, the first pipe 41 is disposed at the bottom of the container 2, and the mounting base 42 is disposed at the bottom of the first pipe 41. When the liquid level in the container 2 is low, the detection device 3 can also detect the liquid pressure. Of course, the first pipe 41 and the mounting base 42 can also be disposed on the side of the container 2 or at other locations.

[0082] In one specific embodiment of this disclosure, reference is made to Figure 4 The diaphragm 5 includes a deformable portion 51 and a support portion 52, with the support portion 52 supporting the deformable portion 51 on the mounting base 42. The deformable portion 51 and the support portion 52 are an integral structure, which can form a cap-shaped structure and protrude in a direction away from the mounting base 42. The deformable portion 51, the support portion 52, and the mounting base 42 of the diaphragm 5 form a sealed cavity 40. The liquid in the inlet area of ​​the detection channel 4 is configured to compress the deformable portion 51 of the diaphragm 5, causing the deformable portion 51 to deform and change the pressure within the sealed cavity 40.

[0083] In other embodiments of this disclosure, the deformable part 51 and the support part 52 are two separate parts. The support part 52 can be fixed on the mounting base 42, and the deformable part 51 covers the top opening of the support part 52 so that the deformable part 51, the support part 52 and the mounting base 42 form a sealed cavity 40.

[0084] Alternatively, a groove can be provided on the mounting base 42, and the deformable part 51 can be provided at the opening end of the groove and the opening end of the groove can be closed, thereby forming a sealed cavity 40 with the deformable part 51 and the groove of the mounting base 42.

[0085] In one specific embodiment of this disclosure, reference is made to Figure 4 The diaphragm 5 also includes a pressing edge 53 disposed at the edge of the support portion 52, the pressing edge 53 extending radially outward. The end of the first pipe 41 is sealed to the mounting base 42 via the pressing edge 53.

[0086] Specifically, the first pipe 41 has an annular flange 411 at one end near the mounting base 42, which engages with the pressing edge 53 of the diaphragm 5. When the first pipe 41 is connected to the mounting base 42, the pressing edge 53 of the diaphragm 5 is pressed between the mounting base 42 and the flange 411 of the first pipe 41, achieving a seal between the first pipe 41 and the mounting base 42. When the diaphragm 5 needs to be replaced, the mounting base 42 can be disassembled and the diaphragm 5 removed, making the operation convenient.

[0087] The pressing edge 53 of the diaphragm 5 can form an annular groove with the support part 52, and the flange 411 of the first pipe 41 can be adapted to the groove. The mounting base 42 is provided with a mounting groove at the end facing the first pipe 41, and the diaphragm 5 is embedded in the mounting groove. When the mounting base 42 is connected to the first pipe 41, the flange 411 extends into the mounting groove and cooperates with the diaphragm 5. The pressing edge 53 of the diaphragm 5 is squeezed between the flange 411 and the inner wall of the mounting groove, thereby strengthening the fixation of the diaphragm 5 and improving the sealing between the first pipe 41 and the mounting base 42.

[0088] In one embodiment of this disclosure, reference is made to Figure 4 The mounting base 42 has a receiving cavity 421 on the side away from the first pipe 41, and the mounting base 42 has a through hole connecting the receiving cavity 421 and the sealing cavity 40. The detection device 3 can be inserted into the receiving cavity 421 from the end of the mounting base 42 away from the first pipe 41. A base plate can also be provided on the mounting base 42. After the detection device 3 is installed, the base plate is fixed to the end of the receiving cavity 421 away from the first pipe 41, thereby confining the detection device 3 in the receiving cavity 421.

[0089] Reference Figure 4The detection device 3 includes a sensor body 30 and a connecting pipe 31 extending from the sensor body 30. The sensor body 30 is located in the receiving cavity 421, and the connecting pipe 31 passes through the through hole and is sealed to the through hole. For example, a sealing ring is provided between the connecting pipe 31 and the inner wall of the through hole to ensure the sealing performance of the sealing cavity 40. When the liquid in the container 2 squeezes the diaphragm 5 and deforms, the pressure in the sealing cavity 40 changes. This pressure change is acted on the thin film inside the sensor body 30 through the connecting pipe 31, thereby detecting the pressure in the sealing cavity 40 by the deformation of the thin film.

[0090] In one embodiment of this disclosure, a first opening 21 is disposed at the bottom of container 2, and a detection channel 4 is disposed below container 2. The top end of detection channel 4 is a first end, communicating with the first opening 21 of container 2, and the bottom end of detection channel 4 is a second end, communicating with detection device 3. Detection device 3 is arranged in an upright position, with its connecting pipe 31 facing upwards and communicating with the detection channel 4 above.

[0091] In one embodiment of this disclosure, reference is made to Figure 3 , Figure 5 A first valve 23 is provided inside the first opening 21 of container 2. When the first valve 23 is open, container 2 is connected to the detection channel 4, allowing the detection device 3 to detect changes in liquid pressure within container 2. When the first valve 23 is closed, it prevents liquid leakage from container 2. The first valve 23 can be an electric valve, an automatic valve, or the like.

[0092] In one embodiment of this disclosure, reference is made to Figure 3 The first end of the detection channel 4, i.e. the end connected to the container 2, is provided with a first connector 43. The first connector 43 is configured to cooperate with the first valve 23 after the first opening 21 of the container 2 is connected to the first pipe 41, so that the first valve 23 moves to the open position, thereby connecting the container 2 with the detection channel 4.

[0093] In one specific embodiment of this disclosure, the first valve 23 includes a valve core, which is disposed at the first opening 21 of the container 2 via an elastic element. The elastic element keeps the valve core in a closed state through its elastic force. One end of the first connector 43 is connected to the inner cavity of the first pipe 41, and the other end faces the first valve 23. When the first pipe 41 is connected to the first opening 21 of the container 2, the first connector 43 is mated with the first valve 23 so that the first connector 43 can push the valve core of the first valve 23, causing the valve core to move away from the detection channel 4 against the action of the elastic element, thereby opening the first valve 23. When disassembling the container 2, the first connector 43 disengages from the valve core of the first valve 23, and the valve core resets under the elastic force of the elastic element, thereby closing the first valve 23. The arrangement of the first valve 23 and the first connector 43 makes the disassembly and assembly of the container 2 more convenient, improving the user experience.

[0094] In one embodiment of this disclosure, the cleaning equipment further includes a control unit, and the detection device 3 is communicatively connected to the control unit. After detecting pressure, the detection device 3 sends information to the control unit, which receives the information and determines the amount of water in the container 2. Specifically, the control unit can calculate the amount of water in the solution based on a preset calculation method.

[0095] The cleaning equipment may also include a prompting device that is communicatively connected to the control unit. The control unit can send calculated solution volume information to the prompting device. The prompting device includes, but is not limited to, at least one of a display screen, a voice device, and a warning light. The user can know the liquid volume in container 2 through the prompting device and thus replenish the liquid in container 2 as needed.

[0096] In one embodiment of this disclosure, the cleaning equipment further includes a pressure sensor for detecting atmospheric pressure. The pressure sensor is communicatively connected to a control unit. Based on the atmospheric pressure detected by the pressure sensor, the control unit compensates for the information received from the detection device 3, thereby improving the accuracy of the calculated solution water volume. Because a pressure sensor is used to compensate for the detection results of the detection device 3, the cleaning equipment of this disclosure can be applied to areas at different altitudes, ensuring the consistency of solution water level detection.

[0097] In the cleaning equipment disclosed in this embodiment, the pressure of the liquid in container 2 can be transmitted to the detection device 3 through the detection channel 4. The diaphragm 5 can separate the liquid inlet area and the pressure-bearing area in the detection channel 4, preventing the liquid from contacting the detection device 3, thereby preventing impurities in the liquid from affecting the detection device 3. It can also solve the problem of the sensor being affected by different water qualities, such as residual water, air bubbles, and other solutions. Furthermore, by detecting the pressure of the liquid in the container in real time, compared to traditional photoelectric or capacitive detection devices, the water level in the container can be detected in real time. Simultaneously, the changes in the water level in the container can be presented to the user in real time, providing a more intuitive experience.

[0098] Example 2

[0099] This embodiment provides a cleaning device, which differs from the first embodiment in that the detection channel 4 in this embodiment forms a liquid inlet area and a pressure zone through means other than the diaphragm 5.

[0100] For details, refer to Figure 6 , Figure 7 A bend 6 is provided between the two ends of the detection channel 4, allowing liquid in container 2 to enter the bend 6 through the first end of the detection channel 4. A gas, such as air, is stored in the pressure zone of the detection channel 4. The liquid entering the bend 6 compresses the gas in the pressure zone, thus transferring the liquid's pressure to the gas. The gas in the pressure zone is connected to the detection device 3, which can detect the gas pressure.

[0101] In one embodiment of this disclosure, the two ends of the bend 6 can be directly connected to the first opening 21 of the container 2 and the detection device 3, respectively, and the bend 6 forms a detection channel 4. The liquid inlet area is located on the side of the bend 6 adjacent to the container 2, and the pressure-bearing area is located on the end of the bend 6 adjacent to the detection device 3.

[0102] In one embodiment of this disclosure, one end of the bend 6 is connected to an opening located at the bottom of the container 2, and the other end extends upward after passing around the bottom of the container 2. That is, both ends of the bend 6 have openings facing upward, making the bend 6 approximately U-shaped or J-shaped. The first opening 21 of the container 2 is located at the bottom of the container 2. In this embodiment, the detection device 3 is arranged in an inverted manner, that is, the detection device 3 is installed at the higher end of the bend 6, and its connecting pipe 31 faces downward, communicating with the lower opening end of the bend 6.

[0103] In one embodiment of this disclosure, reference is made to Figure 6 , Figure 7The detection channel 4 includes a first pipe 41 and a bend 6 disposed on the body 1. The first pipe 41 is configured such that one end is connected to the first opening 21 of the container 2, and the other end is connected to one end of the bend 6. The end of the bend 6 away from the first pipe 41 is connected to the detection device 3. The first pipe 41, the bend 6, and the detection device 3 form the detection channel 4. A pressure zone is formed in the bend 6 in the area adjacent to the detection device 3. The detection device 3 is disposed in the bend 6 at a position higher than the bottom of the bend 6 to prevent liquid at the bottom of the bend 6 from entering the detection device 3; the distance between the detection device 3 and the bottom of the bend 6 is related to the initial pressure of the pressure zone. When the initial pressure of the pressure zone is large, the distance between the detection device 3 and the bottom of the bend 6 can become smaller. This is because the pressure zone itself has a certain initial pressure, so when the liquid in the container 2 flows into the bend 6 and squeezes the pressure zone, the liquid itself is also subject to gas resistance, preventing the liquid from rising in the bend 6.

[0104] In one embodiment of this disclosure, reference is made to Figure 6 One end of the bend 6 connects to the detection device 3, extending upwards so that the installation position of the detection device 3 is at least higher than the highest water level in the container 2. At this time, the initial pressure in the pressurized area is atmospheric pressure, and the container 2 and the bend 6 form a communicating vessel, so that the liquid level in the bend 6 will not reach the height of the detection device 3, thereby preventing the liquid from contacting the detection device 3.

[0105] In one embodiment of this disclosure, the bend 6 and the detection device 3 are disposed inside the body 1. A cavity can be provided in the body 1 to accommodate the bend 6 and the detection device 3. The bend 6 can extend upwards from the side or rear of the mounting cavity 10 in the body 1. The detection device 3 can be positioned above or near the top of the container 2, so that the detection device 3 is at least above the water level of the container 2. Both ends of the first pipe 41 are sealed and connected to the first opening 21 of the container 2 and the bend 6, respectively. The end of the bend 6 furthest from the first pipe 41 is sealed and connected to the detection device 3. For example, a seal can be provided at the connection point to prevent leakage in the detection channel 4, which would affect the accuracy of the detection results.

[0106] The bend 6 can be a flexible or rigid pipe, and the material can be plastic, metal, etc., which are not limited in this disclosure. The connection methods between the bend 6 and the body 1, and between the bend 6 and the detection device 3, include, but are not limited to, threaded connection, screw connection, plug-in connection, welding, bonding, etc.

[0107] In the cleaning equipment disclosed in this embodiment, the pressure of the liquid in container 2 can be transmitted to the detection device 3 through the detection channel 4. The gas stored in the pressurized area of ​​the detection channel 4 separates the liquid in the liquid inlet area from the detection device 3 and can transmit the pressure of the liquid to the detection device 3, preventing the liquid from directly contacting the detection device 3. By setting the bend 6, the gas in the pressurized area can be prevented from overflowing from the liquid inlet area.

[0108] In one embodiment of this disclosure, such as Figure 8 As shown, both the detection device 3 and the bent tube 6 are positioned below the container 2, with both ends of the bent tube 6 facing upwards. The detection device 3 is arranged in an inverted manner, with its sensor body 30 fixed to the body 1. Specifically, the sensor body 30 is positioned below the second opening 22, with its connecting pipe 31 facing downwards and communicating with the bent tube 6 below. The other end of the bent tube 6 is connected below the first opening 21. In this embodiment, the liquid in the container 2 can enter the bent tube 6 and then the connecting pipe 31 of the detection device 3, allowing the detection device 3 to directly detect the liquid pressure. Impurities in the liquid can settle at the bottom of the bent tube 6 under their own gravity, thus avoiding any impact on the detection device 3.

[0109] In one specific embodiment of this disclosure, the body 1 includes an end cap 8 disposed at the bottom of the mounting cavity 10. The detection channel 4 includes a first pipe 41 and a bend 6. The first pipe 41 is disposed in the end cap 8, and the end cap 8 mates with the first opening 21 of the container 2. The upper end of the first pipe 41 is configured as a mating interface, which can be connected to the first opening 21 of the container 2. A spring valve is disposed in the first opening 21, and the upper end of the end cap 8 can be fastened to the bottom end of the spring valve. The detection device 3 is fixedly connected to the bottom of the end cap 8 in an inverted manner. One end of the bend 6 is connected to the lower end of the first pipe 41, and the other end is connected to the detection device 3.

[0110] Example 3

[0111] This embodiment provides a cleaning device, which differs from Embodiment 1 and Embodiment 2 in that it also includes a drainage channel, through which liquid in container 2 can be discharged or replenished.

[0112] In one embodiment of this disclosure, a water pump can be installed on the drainage channel, and the water pump can be mounted on the machine body 1. The water pump controls the liquid in the container to flow out through the drainage channel, for example, into the cleaning device of a cleaning equipment to clean the work surface. The cleaning device of the cleaning equipment can be a cleaning roller brush, a cleaning cloth, or other cleaning tools. Both the water pump and the detection device 3 on the drainage channel are communicatively connected to the control unit of the cleaning equipment. The control unit can control the water pump to turn on or off, and can also control the water pump flow rate.

[0113] The drainage channel can be integrally connected to the body 1, or it can be detachably connected to the body 1 and sealed together. The drainage channel can be a channel located inside the body 1, or it can be a pipe connected to the body 1.

[0114] In one embodiment of this disclosure, reference is made to Figure 9 The drainage channel is connected to the liquid inlet area of ​​the detection channel 4, so that the drainage channel can discharge the liquid in the container 2 through the liquid inlet area of ​​the detection channel 4 and the first opening 21 of the container 2 to supply liquid to the cleaning device.

[0115] In one specific embodiment of this disclosure, reference is made to Figure 9 The drainage channel is configured as a branch pipe 412 connected to the first pipe 41, and the branch pipe 412 is located in the area between the two ends of the first pipe 41. The liquid in the container 2 is configured to flow out through the first pipe 41 and the branch pipe 412. The branch pipe 412 can be integrated with the first pipe 41. The drainage channel may also include other pipes connected to the branch pipe 412 to extend the length of the drainage channel.

[0116] In another embodiment of this disclosure, reference is made to Figure 3 , Figure 7 The container 2 has a second opening 22, and a drainage channel communicates with the second opening 22. The liquid in the container 2 is discharged through the second opening 22 and the drainage channel. The drainage channel and the detection channel 4 are set independently to avoid mutual interference. The second opening 22 can be set at the bottom or side wall of the container 2, or at other locations on the container 2.

[0117] In one embodiment of this disclosure, the second opening 22 is formed at the bottom of the container 2 and is independently set from the first opening 21. The drainage channel and the second opening 22 of the container 2 can be set as an integral structure; or, the drainage channel and the second opening 22 of the container 2 can be set as a detachable connection structure and sealed together. The detachable connection structure includes, but is not limited to, plug-in connection, threaded connection, etc.

[0118] In one embodiment of this disclosure, reference is made to Figure 3 A second valve 24 is provided inside the second opening 22 of container 2. When the second valve 24 is open, container 2 is connected to the drainage channel. When the second valve 24 is closed, leakage of liquid in container 2 can be prevented. The second valve 24 can be an electric valve, an automatic valve, etc.

[0119] In one embodiment of this disclosure, reference is made to Figure 3The drainage channel includes at least a second pipe 7, one end of which is connected to the second opening 22 of the container 2. The drainage channel may also include other pipes connected to the second pipe 7 to extend its length. A second connector 71 is provided at the end of the second pipe 7 that connects to the second opening of the container 2. The second connector 71 is configured to push a second valve 24 to the open position after the container 2 is connected to the second pipe 7, thereby connecting the container 2 to the drainage channel.

[0120] The drainage channel disclosed herein is the main drainage pipe of the container, meaning that the liquid in the container is discharged outwards through the drainage pipe. In embodiments of the cleaning equipment disclosed herein, such as a handheld mop, the cleaning liquid in the container can flow into the drainage pipe through the second opening 22, and through the drainage pipe, the cleaning liquid can flow onto the roller assembly of the mop, achieving the purpose of mopping the floor through the roller assembly. It should be noted that the drainage channel of this disclosure can be a pipe joint or a structure including a connecting hose, which will not be specifically described here.

[0121] In this embodiment, the drainage channel and the detection channel 4 are two isolated channels on the body 1. When the container 2 containing water is installed on the body 1, the drainage channel drains water to the cleaning device of the cleaning equipment. At this time, since the drainage channel and the detection channel 4 are isolated from each other, the liquid flow in the drainage channel will not affect the liquid pressure in the detection channel 4, and the detection result is more accurate and effective.

[0122] In one specific embodiment of this disclosure, the second valve 24 includes a valve core connected to the second opening of the container 2 via an elastic element. The valve core is in a closed state under the elastic force of the elastic element. One end of the second connector 71 is connected to the inner cavity of the second pipe 7, and the other end faces the second valve 24. When the drainage channel is connected to the second opening 22 of the container 2, the second connector 71 pushes the valve core of the second valve 24, causing the valve core to move away from the second pipe 7 against the action of the elastic element, thereby opening the second valve 24. When disassembling the container, the second connector 71 disengages from the valve core of the second valve 24, and the valve core resets under the elastic force of the elastic element, thereby closing the second valve 24. The arrangement of the second valve 24 and the second connector 71 makes the disassembly and assembly of the container more convenient, thereby improving the user experience.

[0123] In one embodiment of this disclosure, reference is made to Figure 3 The machine body 1 is provided with an end cap 8 that can be detachably connected to the container 2. The first pipe 41 and / or the second pipe 7 can be installed on the end cap 8. The connection method between the end cap 8 and the machine body 1 includes, but is not limited to, screw fixing, snap connection, threaded connection, etc. When removing the end cap 8, the first pipe 41 and the second pipe 7 can be removed at the same time.

[0124] In one embodiment of this disclosure, reference is made to Figure 10 The opening at the bottom of container 2 is connected to the second pipe 7 of the drainage channel, so that the liquid in container 2 can be discharged out through the second pipe 7. The bend 6 and the detection device 3 in the above embodiment are also connected to the second pipe 7.

[0125] In detail, such as Figure 10 As shown, the outlet of the second pipe 7 connected to the bend 6 is equipped with a pipe fitting 410. The pipe fitting 410 is inclined upward and connected to one end of the bend 6. The other end of the bend 6 extends upward and is positioned above the water level of the container. The detection device 3 is connected inverted to the end of the bend 6 furthest from the pipe fitting 410, and the detection device 3 is not lower than the highest water level of the container 2. When the container 2 is detached from the body 1 or when there is no liquid in the container 2, the second pipe 7 is in an emptied state, and the detection device 3 can communicate with the outside air through the bend 6 and the second pipe 7. At this time, the pressure detected by the detection device 3 is the outside atmospheric pressure.

[0126] When the container contains liquid and the second pipe 7 is closed, the liquid in the container will enter the second pipe 7. Under pressure, some of the liquid will flow upward into the bend 6. The pressure in the bend 6 changes under the action of the liquid, and the detection device 3 can detect the pressure value in the bend 6.

[0127] It should be noted that those skilled in the art will understand that the bend 6 in the above embodiments can adopt a curved structure, with one end inclined and connected to the pipe joint 410, and the other end extending vertically upward; the bend 6 can also adopt a straight pipe structure, inclined along the direction of the pipe joint 410.

[0128] Example 4

[0129] This disclosure provides a water level detection component that can be applied to cleaning equipment such as floor scrubbers and cleaning robots, as well as other equipment that requires water level detection, such as water heaters.

[0130] Reference Figure 3 The water level detection assembly disclosed herein includes a detection device 3 and a detection channel 4. One end of the detection channel 4 is configured to communicate with a container 2, and the other end is configured to communicate with the detection device 3. The container 2 is used to store liquid. The detection channel 4 includes an inlet area adjacent to the container 2 and a pressurized area adjacent to the detection device 3. The container 2 is provided with a first opening 21, and one end of the detection channel 4 communicates with the first opening 21 of the container 2, while the other end communicates with the detection device 3. Liquid in the container 2 can enter the inlet area of ​​the detection channel 4.

[0131] The liquid in the inlet area is configured as the pressure zone of the squeeze detection channel 4, so that the pressure in the pressure zone changes. The detection device 3 is configured to detect the pressure in the pressure zone, that is, to detect the pressure of the liquid in container 2. When the water level of the liquid in container 2 changes, the pressure transmitted from the inlet area to the pressure zone changes, and the detection device 3 can detect the pressure change in the pressure zone in real time, thereby obtaining the pressure change of the liquid in container 2 in real time.

[0132] In one embodiment of this disclosure, reference is made to Figure 3 A diaphragm 5 can be installed in the detection channel 4, which separates the liquid inlet area and the pressure zone within the detection channel 4. The diaphragm 5 is sealed to the inner wall of the detection channel 4, forming a sealed cavity 40 within the detection channel 4 to prevent liquid from entering the pressure zone and to prevent liquid from contacting the detection device 3. Liquid entering the detection channel 4 from the first opening 21 is configured to deform the diaphragm 5, and the detection device 3 is configured to detect the pressure within the sealed cavity 40.

[0133] In another embodiment of this disclosure, reference is made to Figure 6 , Figure 7 The detection channel 4 includes a first pipe 41 and a bend 6. One end of the first pipe 41 is configured to communicate with the container 2, and the other end is configured to communicate with the bend 6. The detection device 3 is set in the bend 6 at a position higher than the bottom of the bend 6. A pressure zone is formed in the bend 6 in the area adjacent to the detection device 3.

[0134] The liquid in container 2 can enter the bend 6 through the first end of the detection channel 4. Gas is stored in the pressurized zone of the detection channel 4. The liquid entering the bend 6 can compress the gas in the pressurized zone, thereby transferring the liquid's pressure to the gas. The gas in the pressurized zone is connected to the detection device 3, which can detect the gas pressure.

[0135] In this embodiment of the water level detection component, the structure and principle of the detection device 3, detection channel 4, diaphragm 5, bend 6, etc. can all be referred to the above embodiments one, two and three, and will not be repeated in this embodiment.

[0136] The technical solutions adopted in this disclosure will be explained below in the context of specific application scenarios to aid understanding. In the application scenarios below, floor scrubbers are used as an example of cleaning equipment.

[0137] Application Scenario 1

[0138] When the container 2 of the floor scrubber is in the disassembled state, the first valve 23 is closed under the action of the elastic element to prevent the solution from flowing out from the first opening 21. When installing the container 2, the first opening 21 of the container 2 is connected to the first pipe 41 of the detection channel 4. The first connector 43 of the first pipe 41 can push the first valve 23 in the first opening 21 to the open position, so that the container 2 is connected to the detection channel 4. The liquid in the container 2 enters the liquid inlet area of ​​the detection channel 4 through the first opening 21 and squeezes the pressure area, causing the volume of the pressure area to change, thereby transmitting the liquid pressure in the liquid inlet area to the pressure area. The detection device 3 can detect the pressure of the pressure area in real time, thereby detecting the liquid pressure in real time.

[0139] The degree of pressure exerted by the liquid on the pressurized area varies depending on the water level in container 2. For example, when container 2 is full, the pressure exerted by the liquid on the pressurized area is at its maximum, and the pressure value detected by the detection device 3 is also at its maximum. When container 2 is at a low water level, the pressure exerted by the liquid on the pressurized area is less, and the pressure value detected by the detection device 3 is also less.

[0140] The pressure signal detected by the detection device 3 can be used to characterize the volume of liquid in the container. For example, the control unit can calculate the remaining amount of solution in the container based on the information output by the detection device 3 and the corresponding algorithm, and then feed back the remaining amount of liquid to the user through a display screen or an app, thus improving the user experience.

[0141] Application Scenario 2

[0142] When a user uses a floor scrubber to clean the floor, during the cleaning process, the liquid in container 2 enters the first pipe 41 of the detection channel 4 through the first opening 21, and then enters the diversion pipe 412, flowing from the diversion pipe 412 to the cleaning device to clean the floor. After the liquid in container 2 enters the inlet area of ​​the detection channel 4 through the first opening 21, it squeezes the diaphragm 5 inside the detection channel 4. The diaphragm 5 deforms and squeezes the pressure area of ​​the detection channel 4, thereby transmitting the pressure of the liquid to the pressure area. The detection device 3 can detect the pressure of the pressure area in real time. The detection device 3 sends information to the control unit, which receives the information, determines the amount of water in the solution in container 2, and sends the water volume information of the liquid in container 2 to the display screen of the floor scrubber. The user can see the real-time liquid volume in container 2 through the display screen.

[0143] Application Scenario 3

[0144] When a user uses a floor scrubber to clean the floor, liquid in container 2 enters the drain channel through the second opening 22 and is discharged to clean the floor. Liquid in container 2 also enters the bend 6 of detection channel 4 through the first opening 21, compressing the gas in the pressure zone of detection channel 4 and transmitting pressure to the pressure zone. Detection device 3 can detect the pressure in the pressure zone. Detection device 3 sends information to the control unit, which receives the information, determines the amount of liquid in container 2, and sends this information to the floor scrubber's display screen. The user can then view the amount of liquid in container 2 on the display screen.

[0145] Application Scenario 4

[0146] After the user installs container 2 on the body 1, the interface of the detection channel 4 on the body 1 aligns with the first opening 21 at the bottom of container 2. Squeezing opens the spring valve at the first opening 21, allowing liquid in container 2 to flow into the detection channel 4 through the first opening 21. The pressure of the liquid in container 2 can then be detected by the detection device 3. Additionally, the second connector 71 of the second pipe 7 on the body 1 aligns with the second opening 22 at the bottom of container 2, opening the spring valve at the second opening 22. Liquid in container 2 then flows through the second opening 22 into the second pipe 7. When the user uses this cleaning equipment to clean the floor, the water pump draws liquid from the second pipe 7 and directs it to the roller brush assembly for wet mopping.

[0147] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
