[0049] The following description provides numerous specific details to offer a more thorough understanding of the technical solutions provided by this invention. However, it will be apparent to those skilled in the art that the technical solutions provided by this invention can be implemented without one or more of these details.

[0050] It should be noted that the terminology used herein is for the purpose of describing particular embodiments only and is not intended to limit the exemplary embodiments according to the present invention. As used herein, the singular form is intended to include the plural form as well, unless the context clearly indicates otherwise. Furthermore, it should be understood that when the terms "comprising" and / or "including" are used in this specification, they indicate the presence of the stated features, integrals, steps, operations, elements, and / or components, but do not exclude the presence or addition of one or more other features, integrals, steps, operations, elements, components, and / or combinations thereof.

[0051] Exemplary embodiments according to the present invention will now be described in more detail with reference to the accompanying drawings. However, these exemplary embodiments may be implemented in many different forms and should not be construed as being limited to the embodiments set forth herein. It should be understood that these embodiments are provided so that the disclosure of the present invention is thorough and complete, and that the concept of these exemplary embodiments is fully conveyed to those skilled in the art.

[0052] like Figures 1 to 5 As shown, a surface cleaning device is provided according to a first aspect of the present application, including a base assembly 110, a housing assembly 120, and a detection component; the housing assembly 120 is detachably connected to the base assembly 110, and the detection component is disposed on the base assembly 110 and the housing assembly 120. The detection component is used to detect whether the liquid level in the housing assembly 120 has reached a preset height, and also to detect whether the housing assembly 120 is installed in place relative to the base assembly 110.

[0053] By setting the detection component on the base assembly 110 and the housing assembly 120, the detection component can detect whether the liquid level in the housing assembly 120 has reached the preset height and whether the housing assembly 120 is installed in place relative to the base assembly 110. By performing two different functions with one functional component, compared with setting the liquid level detection component and the position detection component separately, the number of parts of the equipment is reduced, the overall structure is simplified, and the assembly difficulty and manufacturing cost are reduced.

[0054] In this technical solution, the detection components are set on the base assembly 110 and the housing assembly 120. When the housing assembly 120 is installed on the base assembly 110, it can be determined whether the housing assembly 120 is installed in place relative to the base assembly 110 by means of forming a circuit or triggering a detection signal, thereby reducing the probability of problems such as leakage and reduced suction efficiency caused by the installation misalignment of the housing 122. At the same time, by setting the detection components, it is possible to detect whether the liquid level of the sewage in the housing 122 has reached the preset height, which can remind the user to empty the sewage in the housing assembly 120 in time, reducing the possibility of liquid overflow contaminating the inside of the equipment or the surface to be cleaned.

[0055] The surface cleaning device provided in this application includes a base assembly 110 and a housing assembly 120, based on which dirt generated during operation can be transported into the housing assembly 120. In other words, the housing assembly 120 is used to store dirt, such as solid dirt and dirty water. Since the housing assembly 120 is set on the base assembly 110, the distance between the housing assembly 120 and the base assembly 110 is very short, resulting in a short dirt transport path. On the one hand, it eliminates the need for long pipes, simplifying the structure; on the other hand, it greatly reduces the probability of dirt accumulation in areas other than the housing assembly 120, reducing odor generation and making the surface cleaning device more hygienic to use; thirdly, it facilitates user cleaning of the housing assembly 120, making the maintenance of the surface cleaning device more convenient; fourthly, regarding the counterweight of the surface cleaning device, when using the handheld surface cleaning device for cleaning operations, setting the housing assembly 120 on the base assembly 110 allows the housing assembly 120 to be relatively far from the user's hand position, bringing the center of gravity of the surface cleaning device closer to the base assembly 110, increasing the grip of the surface cleaning device, improving cleaning ability, and facilitating user movement of the surface cleaning device, making its use more effortless.

[0056] During use, the base assembly 110 can come into contact with the ground. The specific design of the base assembly 110 is not limited in this application; for example, it may include a rotating roller brush, a reciprocating plate-shaped cleaning component, a rotating cleaning disc, etc. All these specific cleaning embodiments are within the scope of protection of this application. Compared to the conventional technology that arranges the clean and dirty water tank within the body 220, this application arranges the tank assembly 120 directly on the base assembly 110, greatly shortening the path of dirt, facilitating dirt collection, inhibiting the generation of bacteria and odors, simplifying the maintenance of the surface cleaning device, and improving the user experience.

[0057] The detection assembly includes a first detection unit 130 and a second detection unit 140. The first detection unit 130 is disposed in the housing assembly 120 and extends into the housing assembly 120. The second detection unit 140 is disposed in the base assembly 110. When the housing assembly 120 is installed in the base assembly 110, the first detection unit 130 and the second detection unit 140 form a first circuit.

[0058] By setting up a first detection unit 130 and a second detection unit 140 to form a first circuit, when the housing assembly 120 is installed onto the base assembly 110, the first detection unit 130 and the second detection unit 140 are physically aligned and in contact to form a first circuit, providing feedback on the installation status. By performing two different functions through a single functional component, the number of parts in the equipment is reduced, the overall structure is simplified, and assembly difficulty and manufacturing costs are lowered.

[0059] In this technical solution, the tank assembly 120 has an internal space for storing sewage. A part of the first detection unit 130 is fixed on the tank assembly 120, and the other part extends into the internal space. As the surface cleaning device works, the sewage level rises continuously. When the sewage comes into contact with the first detection unit 130, due to the conductivity of the sewage, the first detection unit 130 and the second detection unit 140 form a complete circuit, thereby enabling the detection of the liquid level height inside the tank assembly 120.

[0060] In this technical solution, after the housing assembly 120 is installed onto the base assembly 110, the first detection unit 130 and the second detection unit 140 come into contact and conduct, forming a first circuit. The formation of the first circuit reflects the assembly status of the housing assembly 120 and the base assembly 110. If the housing 122 is not installed correctly, the first circuit cannot conduct, prompting the user to adjust it, thus avoiding problems such as leakage and reduced suction efficiency caused by loosening or misalignment of the housing assembly 120.

[0061] The first detection unit 130 includes a first conductive connector 230 and at least two probes 131. The fixed section 1311 of the probes 131 is connected to the housing assembly 120, and the extension section 1312 of the probes 131 extends into the housing assembly 120. The first conductive connector 230 is connected to at least two probes 131. The position of the first conductive connector 230 is higher than that of the extension section 1312. The conductivity of the first conductive connector 230 is different from the conductivity of the liquid stored in the housing assembly 120.

[0062] In this technical solution, the structure of the first detection unit 130 is further provided. The first detection unit 130 may include at least two probes 131 and a detection circuit 260. Based on this, when the probes 131 are immersed in the liquid, the detection circuit 260 will be turned on by utilizing the conductivity of the liquid. Based on this, the height of the liquid level can be detected, and a prompt message can be issued to remind the user to empty the sewage in the tank 122.

[0063] In some examples, the detection circuit 260 may include multiple metal parts, which may be strip-shaped or rod-shaped, etc. The metal parts are connected to the probe 131 and then to the cable. This can ensure the mechanical strength of the detection components and reduce the probability of the detection circuit 260 becoming loose.

[0064] The first conductive connector 230 is connected to the insertion section 1312 of each probe 131.

[0065] By connecting the first conductive connector 230 to the extension section 1312 of each detection element, the electrical signal can be transmitted to the second detection unit 140 more accurately.

[0066] This technical solution further provides the structural composition of the probe 131. The probe 131 is generally a strip structure, with a fixed section 1311 and an extension section 1312 being two sections along the length of the probe 131. Both the fixed section 1311 and the extension section 1312 have a certain length. The fixed section 1311 can be horizontally positioned and thus fixedly connected to the top of the housing assembly 120. The horizontally positioned fixed section 1311 has a larger contact area with the top of the housing assembly 120, resulting in a more stable connection. The extension section 1312 can be vertically positioned, with its bottom for contact with the liquid.

[0067] The first conductive connector 230 includes conductive plastic, the conductivity of which is less than the conductivity of the liquid stored in the housing assembly 120.

[0068] By utilizing the difference in conductivity between conductive plastic and liquid, and through changes in current of the same detection component, both the positioning and liquid level detection of the housing assembly 120 are performed simultaneously. This eliminates the need for two separate detection devices, reducing the number of parts, simplifying the internal structure of the equipment, lowering assembly complexity and manufacturing costs, and also accommodates the compact layout of the housing assembly 120 and the base assembly 110.

[0069] In this technical solution, when the housing assembly 120 is installed in place, the second circuit formed by the first detection unit 130 and the second detection unit 140 conducts electricity only through the first conductive connector 230 made of conductive plastic. Since the conductivity of the conductive plastic is much lower than that of the liquid stored inside the housing assembly 120, only a small current can be generated in the second circuit at this time. This current signal is only related to the physical connection state between the housing assembly 120 and the base assembly 110, and is completely unrelated to factors such as the presence of liquid or the liquid level. By determining whether current is generated in the second circuit and the magnitude of the current, it can be determined whether the housing assembly 120 is installed in place. When not installed in place, no current is generated in the second circuit; after installation, a small current within a set range is generated in the second circuit, meaning that the current flowing through the second detection unit 140 is small and within a preset range.

[0070] In this technical solution, when the liquid immerses the insertion section 1312 of the detection element, the liquid, as a highly conductive medium, participates in conduction, forming a first circuit together with the first conductive connector 230. Since the conductivity of the liquid is significantly higher than that of conductive plastic, the resistance of the first circuit decreases significantly, and the current increases significantly, clearly distinguishing it from the small current signal of the second circuit. In other words, the current flowing through the second detection section 140 is larger and falls within a preset range. Due to the large difference between the two current signals, the detection circuit 260 can distinguish between position detection and liquid level detection using a simple threshold judgment.

[0071] The housing assembly 120 includes a housing 122 and a plate 1231. The plate 1231 is connected to the housing 122 and is used to divide the housing 122 into a separation space and a wastewater containing space. The extension section 1312 extends through the plate 1231 into the wastewater containing space, and the distance between the extension section 1312 and the bottom of the wastewater containing space is a preset height. When the liquid level in the housing assembly 120 reaches the preset height, the first detection unit 130 and the second detection unit 140 form a second circuit.

[0072] The separation space and the waste liquid containing space are separated by the plate 1231, making the waste liquid containing space an independent liquid storage area. The extension section 1312 extends into the waste liquid containing space to contact and detect the waste liquid level, reducing interference from solid impurities. A gap is left between the extension section 1312 and the bottom of the waste liquid containing space; this gap distance is the preset height of the liquid level. When the liquid level in the housing assembly 120 reaches the preset height, the liquid acts as a conductive medium, connecting the first detection unit 130 and the second detection unit 140 to form a second circuit, enabling feedback of the liquid level.

[0073] In this technical solution, the plate 1231 is provided with a perforation 1233 and a filter element 1232. The perforation 1233 connects the separation space and the waste liquid containing space. The filter element 1232 is located within the separation space. During the operation of the cleaning equipment, dirt is adsorbed onto the filter element 1232 under negative pressure, and then the liquid flows through the perforation 1233 and the filter element 1232 under the action of gravity and enters the waste liquid containing space. Solid waste is stored within the filter element 1232, thereby completing solid-liquid separation.

[0074] In this technical solution, by making the housing assembly 120 include a plate 1231, a filter element 1232 and a through hole 1233, solid-liquid separation can be achieved by using a mechanical structure combined with the gravity flow of liquid, making the product work more stable, with a low failure rate, and reducing the cost of cleaning equipment.

[0075] Understandably, during normal operation of the cleaning equipment, the separation space is located at the top of the waste liquid containing space. That is to say, the dirt will first be transported to the separation space under negative pressure, and then filtered by the filter element 1232. The liquid can then flow into the waste liquid containing space at the bottom under gravity.

[0076] The housing assembly 120 includes a separator 127 disposed on the plate 1231 to separate the sewage inlet 1251 and the air outlet 1261 of the housing assembly 120. A first conductive connector 230 is disposed on the separator 127. A fixed section 1311 extends horizontally toward the first conductive connector 230 and is connected to the first conductive connector 230. An insert section 1312 extends vertically through the plate 1231 into the sewage containing space.

[0077] Considering that airflow always flows towards the area of ​​lowest pressure, after dirt enters the separation space, liquid may enter the air outlet 1261 under the action of airflow. Based on this, an isolation element 127 can be set on the plate 1231. The isolation element 127 blocks the filter element 1232, the dirt inlet 1251 and the air outlet 1261. Based on this, it is difficult for the liquid that has just entered the separation space to be directly adsorbed to the air outlet 1261. By setting the isolation element 127, the length of the airflow path in the separation space is increased. With the longer propagation path, the probability of water vapor contaminating the negative pressure component can be further reduced, achieving a better air-water isolation effect.

[0078] By connecting the fixed section 1311 to the first conductive connector 230, the isolator 127 can provide stable support for the first conductive connector 230. The extension section 1312 extends vertically through the plate 1231 and into the sewage containing space, allowing for a more direct response to changes in liquid level.

[0079] An insulating sleeve is fitted on the outer wall of at least the portion of probe 131 located within the separation space.

[0080] The separation space may contain moisture, small amounts of splashed dirty liquid, or residual solid impurities. These impurities or residual liquid on them may be conductive. The insulating sleeve can prevent the portion of probe 131 located in the separation space from conductive contact with the surrounding environment, leaving only the portion of the probe 1312 located in the dirty liquid containing space as a conductive channel with the liquid. When the liquid in the dirty liquid containing space submerges the probe 1312, an effective conductive circuit is formed, reducing false detections caused by moisture and impurities in the separation space and improving the accuracy of liquid level judgment.

[0081] In this technical solution, an insulating sleeve is fitted on the outer peripheral wall of the extension section 1312. The bottom end of the extension section 1312 is not fitted with an insulating sleeve, so that the bottom end of the extension section 1312 can come into contact with the liquid to form a conductive circuit.

[0082] The insulating sleeve is made of insulating material, such as insulating rubber.

[0083] There are two probes 131, which are arranged along the length of the box 122. The shortest distance between the two probes 131 is D, and the length of the separation space is L, where D = 1 / 2L to 2 / 3L.

[0084] By setting a reasonable spacing between the two probes 131, the probability of false alarms caused by conductive debris simultaneously adhering to both probes 131 is reduced.

[0085] In this technical solution, the distance between the two probes 131 is not less than half the length of the separation space and not more than two-thirds of the length of the separation space.

[0086] The two probes 131 are symmetrically arranged about the vertical plane that bisects the length of the housing 122.

[0087] Along the length of the housing 122, the portion of the fixed section 1311 of the two probes 131 that is away from the extension section 1312 bends outward.

[0088] By bending the portion of the fixed section 1311 away from the extension section 1312 outwards along the length of the housing 122, the contact area between the fixed section 1311 and the housing 122 is increased, further ensuring the connection strength. Meanwhile, since there are many components in the middle of the housing assembly 120, such as air ducts, by extending the portion of the fixed section 1311 away from the extension section 1312 separately along the length of the housing 122, avoidance can be achieved.

[0089] In this technical solution, the portion of the fixed section 1311 near the extending section 1312 extends along the width direction of the separation space. The portion of the fixed section 1311 away from the extending section 1312 extends along the length direction of the separation space.

[0090] The second detection unit 140 includes a detection circuit 260 and at least two second conductive connectors 240. The at least two second conductive connectors 240 are disposed on the base assembly 110. When the housing assembly 120 is installed on the base assembly 110, the first detection unit 130 abuts against the at least two second conductive connectors 240 to form a first circuit. The detection circuit 260 is connected to the second conductive connectors 240.

[0091] By providing at least two second conductive connectors 240, they can form corresponding connections with at least two probes 131 of the first detection unit 130. When the housing assembly 120 is installed in place, each probe 131 of the first detection unit 130 can abut against the corresponding second conductive connector 240 to form a circuit. Even if one connection point fails, the other connection point can still form an effective circuit, ensuring that the position detection function is not interrupted and improving the stability of equipment operation.

[0092] In this technical solution, the second conductive connector 240 can be made of metal material, which has good conductivity and a certain rigidity, so that the second conductive connector 240 can stand up and then abut against the probe 131.

[0093] In this technical solution, when the housing assembly 120 is installed onto the base assembly 110, the first detection unit 130 moves downward with the housing assembly 120 and then comes into contact with the second conductive connector 240 located below, forming a circuit.

[0094] In this technical solution, there are two second conductive connectors 240, and each second conductive connector 240 is configured to correspond one-to-one with a probe 131. The detection circuit 260 can determine the liquid level and the position of the tank assembly 120 based on the magnitude of the flowing current.

[0095] In some examples, the detection circuit 260 may be located inside the housing 122.

[0096] The housing assembly 120 includes a cover unit 128 and a housing 122, with the cover unit 128 covering the housing 122. The first detection unit 130 includes a sliding conductive element, slidably disposed on the housing 122, and connected to the first detection unit 130. When the cover unit 128 is placed on the housing 122, the cover unit 128 drives the sliding conductive element to slide, thereby abutting against the second conductive connector 240.

[0097] The cover unit 128 is part of the housing assembly 120. After the cover unit 128 is assembled onto the housing 122, the housing assembly 120 is then assembled onto the base assembly 110, which can perform the positioning detection function of the housing assembly 120. At the same time, when the cover unit 128 is in place, the sliding conductive part is directly driven to abut against the second conductive connector 240 through mechanical linkage to form a circuit, directly linking the closing action with the circuit conduction, reducing problems such as liquid leakage and negative pressure failure caused by improper closing, and enhancing the safety of equipment operation.

[0098] In this technical solution, the sliding conductive component is flexibly connected to the first detection unit 130 via wires or the like, which reduces the risk of the sliding conductive component disconnecting from the first detection unit 130 after multiple sliding operations.

[0099] In this technical solution, when the cover unit 128 is not covered on the box 122, the sliding conductive part can be in the initial position by means of springs and other components. The sliding conductive part is separated from the second conductive connector 240, and no circuit is formed between the first detection part 130 and the second detection part 140. At this time, it can be determined that the box assembly 120 is not assembled with the base assembly 110.

[0100] As an installation method, when the cover unit 128 is placed on the housing 122 and in place, the cover unit 128 contacts the top of the sliding conductive element and applies a downward force, pushing the sliding conductive element to slide downward on the housing assembly 120. After the cover unit 128 is in place, the sliding conductive element slides to its limit position. When the housing assembly 120 is assembled onto the base assembly 110, the bottom of the sliding conductive element abuts against the second conductive connector 240 below, forming a circuit, indicating that the housing assembly 120 is installed in place.

[0101] As another installation method, first install the part of the housing assembly 120 except for the cover unit 128 onto the base assembly 110, and then cover the housing 122 with the cover unit 128. The cover unit 128 contacts the top of the sliding conductive member and applies a downward force to push the sliding conductive member to slide down on the housing assembly 120. When it slides to the limit position, the bottom of the sliding conductive member abuts against the second conductive connector 240 below to form a circuit, and then it is determined that the housing assembly 120 is installed in place.

[0102] In some examples, to keep the detection circuit 260 relatively away from liquids and dirt and to improve the service life of the detection circuit 260, the detection circuit 260 may be arranged inside the cover unit 128.

[0103] like Figures 6 to 7 As shown, a second aspect of the embodiments of this application discloses a cleaning device, including a surface cleaning apparatus as described above and a body 220. The body 220 is connected to the base assembly 110. The cleaning device also includes a clean water tank and a power supply assembly, the clean water tank being disposed within the body 220. The power supply assembly is disposed within the body 220, located on the side of the clean water tank opposite to the surface cleaning apparatus.

[0104] The cleaning equipment provided in this application includes surface cleaning devices as described in any of the above technical solutions, and therefore possesses all the beneficial effects of the surface cleaning devices described in the above technical solutions.

[0105] In this technical solution, the cleaning equipment may also include a body 220 and a surface cleaning device. Users can hold the handle to move the cleaning equipment so that the base assembly 110 comes into contact with the surface to be cleaned, thereby achieving the cleaning of the surface.

[0106] The cleaning equipment also includes: a clean water tank, which is located inside the body 220; and a power supply component, which is located inside the body 220 on the side of the clean water tank opposite to the surface cleaning device.

[0107] This technical solution further provides the structural composition of the cleaning equipment. The cleaning equipment may also include a water tank and a power supply component. The water tank supplies water or cleaning fluid to the base assembly 110 of the surface cleaning device. Then, the cleaning component 210 of the base assembly 110 is displaced relative to the ground, allowing the cleaning component 210 to clean the ground. Simultaneously, the negative pressure component within the cleaning equipment provides negative pressure to the dirt collection component, completing the dirt collection process. The power supply component provides power to the base assembly 110 and the negative pressure component. The water tank is located inside the body 220. Even if there is a long distance between the water tank and the base assembly 110, and even if water remains in the body 220, it will not produce or will produce very little odor. At the same time, the power supply component is located on the side of the water tank away from the surface cleaning device, which allows for a more balanced configuration of the body 220 and more efficient use of the space within the body 220, making the cleaning equipment structure more compact.
