Description

Technical Field

[0001] This disclosure relates to the field of cleaning equipment technology, and more particularly to a surface cleaning device. Background Technology

[0002] Wet surface cleaning equipment is suitable for cleaning surfaces such as tiles, hardwood floors, and soft carpet surfaces.

[0003] When cleaning a surface in a wet surface cleaning device, the cleaning liquid is first delivered to the cleaning module, and then applied to the surface through the cleaning module. When the cleaning module and the surface to be cleaned move relative to each other, the surface is cleaned.

[0004] CN113243833A discloses an automatic control method for cleaning equipment and the cleaning equipment itself. It discloses integrating a detection device on the rolling wheel of the cleaning equipment to detect the movement direction and speed signals of the rolling wheel, and performing feedback control on the cleaning equipment based on the signals.

[0005] However, the rollers of surface cleaning equipment are usually supported by a fixed rotating shaft during use. In some smooth surfaces, they may slip. In this case, the redundant rotation of the rollers will send an error signal to the controller of the surface cleaning equipment, causing the surface cleaning equipment to suddenly change its behavior during use, which will cause great inconvenience to the user.

[0093] The present disclosure will now be described in further detail with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the scope of the disclosure. Furthermore, it should be noted that, for ease of description, only the parts relevant to the present disclosure are shown in the accompanying drawings.

[0094] It should be noted that, where there is no conflict, the embodiments and features described in this disclosure can be combined with each other. The technical solutions of this disclosure will now be described in detail with reference to the accompanying drawings and embodiments.

[0095] Unless otherwise stated, the exemplary implementations / embodiments shown are to be understood as providing exemplary features of various details that provide ways in which the technical concepts of this disclosure can be implemented in practice. Therefore, unless otherwise stated, the features of various implementations / embodiments may be additionally combined, separated, interchanged and / or rearranged without departing from the technical concepts of this disclosure.

[0096] The use of crosshairs and / or shading in the accompanying drawings is generally used to clarify the boundaries between adjacent components. Thus, unless otherwise stated, the presence or absence of crosshairs or shading does not convey or indicate any preference or requirement for the specific material, material properties, dimensions, proportions, commonalities between the illustrated components, or any other characteristics, properties, etc., of the components. Furthermore, in the accompanying drawings, the dimensions and relative dimensions of components may be exaggerated for clarity and / or descriptive purposes. When exemplary embodiments can be implemented differently, a specific process sequence may be performed in a different order than that described. For example, two consecutively described processes may be performed substantially simultaneously or in the reverse order of their description. Furthermore, the same reference numerals denote the same components.

[0097] When a component is referred to as being "on" or "above" another component, "connected to," or "joined to" another component, the component may be directly on, directly connected to, or directly joined to the other component, or there may be intermediate components. However, when a component is referred to as being "directly on" another component, "directly connected to," or "directly joined to" another component, there are no intermediate components. Therefore, the term "connection" can refer to a physical connection, an electrical connection, etc., and may or may not have intermediate components.

[0098] For descriptive purposes, this disclosure may use spatial relative terms such as “below,” “under,” “below,” “down,” “above,” “above,” “higher,” and “side (e.g., in a “sidewall”)” to describe the relationship between one component and another component as shown in the accompanying drawings. In addition to the orientations depicted in the drawings, the spatial relative terms are also intended to encompass different orientations of the device during use, operation, and / or manufacture. For example, if the device in the drawings is flipped, a component described as “below” or “under” another component or feature would subsequently be positioned “above” said other component or feature. Thus, the exemplary term “below” can encompass both “above” and “below” orientations. Furthermore, the device may be otherwise positioned (e.g., rotated 90 degrees or in other orientations), thus interpreting the spatial relative descriptive terms used herein accordingly.

[0099] The terminology used herein is for the purpose of describing particular embodiments and is not intended to be limiting. As used herein, unless the context clearly indicates otherwise, the singular forms “a” and “the” are intended to include the plural forms as well. Furthermore, when the terms “comprising” and / or “including” and variations thereof are used in this specification, it indicates the presence of the stated features, integrals, steps, operations, parts, components, and / or groups thereof, but does not exclude the presence or addition of one or more other features, integrals, steps, operations, parts, components, and / or groups thereof. It should also be noted that, as used herein, the terms “substantially,” “about,” and other similar terms are used as approximate terms rather than as terms of degree, thus explaining the inherent biases in measurements, calculated values, and / or provided values ​​that would be recognized by one of ordinary skill in the art.

[0104] First refer to Figures 1 to 5 The surface cleaning apparatus 1000 disclosed herein will be described.

[0105] refer to Figures 1 to 5 The surface cleaning apparatus 1000 disclosed herein is used for wet cleaning of a surface to be cleaned. The surface cleaning apparatus 1000 is capable of distributing cleaning liquid to the surface to be cleaned and recovering used cleaning liquid and dirt from the surface to be cleaned. The surface cleaning apparatus 1000 includes:

[0106] Cleaning liquid storage unit 220, the cleaning liquid storage unit 220 is used to store cleaning liquid;

[0107] The cleaning base 100 includes an agitator 110 (e.g., a roller brush) configured to make frictional contact with the surface to be cleaned.

[0108] The cleaning base 100 is connected to the cleaning liquid storage unit 220 to receive the cleaning liquid provided by the cleaning liquid storage unit 220. The cleaning base 100 can move on the surface to be cleaned. The cleaning liquid provided by the cleaning liquid storage unit 220 is distributed to the surface to be cleaned by the stirring member 110. The used cleaning liquid and dirt on the surface to be cleaned are sucked up by the suction port 120 of the cleaning base 100 to recycle the used cleaning liquid and dirt on the surface to be cleaned.

[0109] The recycling and storage unit 230 is connected to the cleaning base 100 to receive and store the used cleaning liquid and dirt on the surface to be cleaned recycled by the cleaning base 100.

[0110] The suction source is used to apply negative pressure to the recycling storage unit 230 and provide negative pressure to the suction port 120 through the recycling storage unit 230 so as to draw the used cleaning liquid and dirt on the surface to be cleaned into the recycling storage unit 230.

[0111] The main body 200 is used to accommodate at least the cleaning liquid storage unit 220 and the recycling storage unit 230.

[0112] At least one roller 130 is disposed on the cleaning base 100, and the roller 130 facilitates the reciprocating movement of the cleaning base 100 relative to the surface to be cleaned;

[0113] A self-adjusting detection subsystem 140 includes a support assembly 141 pivotally coupled to at least a portion of the bottom of a cleaning base 100, and a rolling detector 142 coupled to the support assembly 141 for detecting movement of the cleaning base 100 relative to the surface to be cleaned. The support assembly 141 automatically operates in response to torque variations of the rolling detector 142 to change the height of the rolling detector 142 relative to the cleaning base 100.

[0114] In some application scenarios of the surface cleaning device 1000, the cleaning base 100 is moved back and forth by the user, and the torque on the rolling detector 142 will change (the direction of the static friction force will change). If the rolling detector 142 has a fixed height relative to the cleaning base 100 (for example, the rolling detector 142 protrudes a fixed size from the bottom of the cleaning base), the rolling detector 142 may slip, which may lead to errors in the detection of the movement direction of the cleaning base 100.

[0115] The surface cleaning device 1000 disclosed herein, by providing a rolling detector 142, can accurately detect the movement direction (front and back direction) of the cleaning base 100. By providing a support component 141 that is pivotally mounted to the bottom of the cleaning base 100, when the torque received by the rolling detector 142 changes, the support component 141 can automatically operate / act in response to the change in the torque received by the rolling detector 142, thereby causing the height of the rolling detector 142 relative to the cleaning base 100 to change accordingly, thus avoiding problems such as slippage of the rolling detector 142 when the torque received by the rolling detector 142 changes.

[0116] In some embodiments of this disclosure, the rolling detector 142 includes a rolling element (e.g., an auxiliary wheel described below) that rolls into contact with the surface to be cleaned, and a detector (e.g., a disk encoder described below) capable of detecting at least the rolling direction of the rolling element.

[0117] Figure 1 and Figure 2 The structure of a surface cleaning device 1000 according to one embodiment of the present disclosure is shown in general. The surface cleaning device 1000 includes a cleaning base 100, a main body 200 and a handle assembly 300.

[0118] Figure 1 and Figure 2 All show a cleaning liquid storage unit 220, a recycling storage unit 230, and a display screen assembly 280.

[0119] In some embodiments of this disclosure, the main body 200 is pivotally connected to the cleaning base 100, so that the main body 200 can be in a posture parallel to or perpendicular to the surface to be cleaned, so that the surface cleaning device 1000 can operate in a lying cleaning mode and an upright cleaning mode, etc.

[0120] In some embodiments of this disclosure, the suction source of the surface cleaning device 1000 is disposed within the first sub-housing 281 of the main body 200. The suction source may be a suction motor or the like. This disclosure does not impose any particular limitation on the suction source. Any adjustments made by those skilled in the art to the type / configuration of the suction source under the guidance of the technical solutions of this disclosure shall fall within the protection scope of this disclosure.

[0121] In some embodiments of this disclosure, the surface cleaning device 1000 further includes a separation device disposed on the main body 200. A portion of the separation device is located within the second sub-housing 282 of the main body, and another portion is located within the recovery storage section 230. By providing the separation device, the fluid in the recovery storage section 230 can be separated from the gas to form a solid / liquid / solid-liquid mixture, ensuring that the airflow discharged outside the surface cleaning device 1000 does not contain any solid / liquid / solid-liquid mixture. Figure 1 The diagram shows the airflow outlet 2822, which prevents the surface cleaning equipment from causing secondary pollution to the surrounding environment during the cleaning process.

[0122] Both the cleaning liquid storage unit 220 and the recovery storage unit 230 can be detachably installed on the main body 200 of the surface cleaning equipment 1000.

[0123] The cleaning liquid storage unit 220, the recovery storage unit 230, the suction source, the separation device, etc. disclosed herein can all adopt the corresponding or similar structures in Chinese Patent CN114376459A. This disclosure does not impose any special limitations on this. Any adjustments made by those skilled in the art to the specific types / structures of the cleaning liquid storage unit 220, the recovery storage unit 230, the suction source, the separation device, etc., under the guidance of the technical solution disclosed herein, shall all fall within the protection scope of this disclosure.

[0124] refer to Figure 3 and Figure 4 The cleaning base 100 of this disclosure is adapted to contact the surface to be cleaned to perform a wet cleaning operation or a dry cleaning operation on the surface to be cleaned.

[0125] The stirring element 110 of the cleaning base 100 disclosed herein may adopt a roller brush structure. The cleaning base 100 may also include a drive mechanism for driving the stirring element 110 and a fluid distributor for distributing cleaning liquid to the outer surface of the stirring element 110. Both may adopt the corresponding structure or similar structure in Chinese Patent CN114376459A. This disclosure does not make any special limitations on this. Any adjustments made by those skilled in the art to the specific type / structure of the stirring element, drive mechanism, fluid distributor, etc., under the guidance of the technical solution disclosed herein, shall fall within the protection scope of this disclosure.
