The present disclosure also relates to a dirty liquid container and a surface cleaning device comprising the dirty liquid container cover assembly. Background Art

[0002] With the development of automated cleaning equipment, more and more automated cleaning equipment, such as floor scrubbers and robot vacuums, are becoming the preferred choice for commercial and domestic cleaning due to their high efficiency and labor-saving features. Automated cleaning equipment can automatically complete cleaning tasks such as vacuuming, sweeping, and mopping, significantly improving cleaning efficiency while reducing manual labor intensity. Wet cleaning equipment (such as floor scrubbers) is a highly efficient floor cleaning device that uses a wet cleaning fluid (such as water). It is suitable for a variety of floor surfaces, such as ceramic tiles and marble, and is particularly suitable for use in places such as shopping malls, schools, hospitals, and homes.

[0003] However, in some hard-to-clean areas, such as low spaces like the bottom of a sofa or bed, the cleaning device needs to be placed in a flat position so that the user can push and pull it back and forth to clean these areas. When in the flat position, due to the flat position and the oscillating surge effect caused by pushing and pulling (similar to the tidal surge phenomenon in the ocean, where water flows back and forth), the dirty liquid in the dirty liquid container used to collect and store the dirty liquid can easily enter the fan module, causing the fan module to malfunction and not operate normally.

[0004] Therefore, a solution that can overcome the above-mentioned drawbacks is needed. Utility Model Content

[0005] The present disclosure aims to provide a better solution to the above problem, thereby preventing the dirty liquid in the dirty liquid container from flowing into the blower module when the surface cleaning device is in a flat state.

[0008] According to some embodiments of the present disclosure, the extension portion is located at the periphery of the dirty liquid blocking member and is inclined toward the center of the dirty liquid blocking member.

[0009] According to some embodiments of the present disclosure, the solid-liquid separation member is located between the cover and the dirty liquid blocking member, and the dirty liquid blocking member and the solid-liquid separation member are spaced apart from each other.

[0010] According to some embodiments of the present disclosure, a periphery of the dirty liquid blocking member is adjacent to the dirty liquid container, and a gap is formed between the dirty liquid blocking member and an inner wall of the dirty liquid container to allow the dirty liquid to pass through.

[0011] According to some embodiments of the present disclosure, the dirty liquid blocking member and the solid-liquid separation member have corresponding cross sections.

[0012] According to some embodiments of the present disclosure, the dirty liquid container further includes a dirty liquid channel, and under the action of the suction airflow generated by the fan module, the dirty liquid can enter the dirty liquid container through the dirty liquid channel.

[0014] According to some embodiments of the present disclosure, the dirty liquid container cover assembly further includes an airflow guiding member, wherein the airflow guiding member forms an airflow channel in fluid communication with the blower module to extend the airflow path to the blower module.

[0015] According to some embodiments of the present disclosure, the dirty liquid container cover assembly further includes two airflow guiding members respectively located on both sides of the dirty liquid channel.

[0016] According to some embodiments of the present disclosure, the dirty liquid container cover assembly further includes a dirty liquid detection point to detect the liquid level of the dirty liquid and trigger a protection function when the liquid level exceeds a liquid level threshold.

[0017] According to another aspect of the present disclosure, a dirty liquid container is provided, comprising: the dirty liquid container cap assembly as described above; and a dirty liquid container housing, wherein a portion of the dirty liquid container cap assembly is accommodated in the dirty liquid container housing, thereby defining a dirty liquid cavity for storing dirty liquid.

[0018] According to yet another aspect of the present disclosure, a surface cleaning device is provided, comprising: the aforementioned dirty liquid container; and a blower module, wherein the dirty liquid container is in fluid communication with the blower module.

[0028] The present disclosure will be described below with reference to the accompanying drawings. It should be understood that the detailed description and specific examples, while explaining exemplary embodiments of the dirty liquid container cover assembly, dirty liquid container, and surface cleaning device, are intended for illustrative purposes only and are not intended to limit the scope of the present disclosure. These and other features, aspects, and advantages of the dirty liquid container cover assembly, dirty liquid container, and surface cleaning device of the present disclosure can be better understood in conjunction with the following description, the attached claims, and the accompanying drawings. It should be understood that the drawings are merely schematic and not drawn to scale. It should also be understood that the same figure numbers represent the same or similar parts throughout the drawings. The orientation expressions mentioned in this specification are merely described with reference to the directions in the drawings and are not limited thereto.

[0029] Figure 1 An example of a surface cleaning apparatus 1 is shown schematically. Figure 1 As shown in the figure, the surface cleaning device 1 is a pole-type cleaning device and includes a handle for the user to hold. However, the surface cleaning device of the present disclosure is not limited to what is shown in the figure, but can be any suitable surface cleaning device. The surface cleaning device 1 may include a roller brush (not shown), and during the cleaning operation, a cleaning liquid (for example, water) may be distributed onto the roller brush to wet clean the surface to be cleaned. Subsequently, the dirt and the dirty liquid can be sucked into the surface cleaning device 1 together. The surface cleaning device 1 includes a dirty liquid container 10, which can be used to collect and store the sucked dirt and / or dirty liquid. The surface cleaning device 1 also includes a fan module 20 for suction, wherein the dirty liquid container 10 is fluidically connected to the fan module 20 to collect the dirt and / or dirty liquid sucked by the fan module 20 into the dirty liquid container 10.

[0030] The axis A of the surface cleaning apparatus has an angle α with the surface to be cleaned 11 , which may be any suitable angle for performing the cleaning operation, for example, between 0 and 90 degrees. Figure 1 1 shows the surface cleaning device 1 in a flat position, for example, to clean the floor beneath a sofa or bed, i.e., the axis A of the surface cleaning device is adjacent to the surface to be cleaned 11. When the surface cleaning device 1 is in the flat position, the angle α between the axis A of the surface cleaning device and the surface to be cleaned 11 is relatively small, for example, in the range of approximately 0 to 10 degrees. When the surface cleaning device 1 is in an upright position, the angle between the axis A and the surface to be cleaned 11 can be close to 90 degrees.

[0031] In some embodiments, the surface cleaning apparatus further comprises an angle sensing device and a control device. The control device is configured to reduce the power of the blower module 20 when the angle sensing device detects that the surface cleaning apparatus 1 is in a flat position, thereby preventing dirty liquid from entering the blower module 20. The control device can be a suitable device such as a microprocessor or microcontroller. The angle sensing device can include an angle sensor or a distance sensor.

[0032] Figure 2 A dirty liquid container 10 according to the present disclosure is schematically illustrated. The dirty liquid container 10 includes a dirty liquid container cap assembly 100 and a dirty liquid container housing 200. The dirty liquid container cap assembly 100 is configured to cover at least the dirty liquid container. At least a portion of the dirty liquid container cap assembly 100 can be accommodated in the dirty liquid container housing 200. A dirty liquid cavity 201 for storing dirty liquid is defined between the dirty liquid container cap assembly 100 and the dirty liquid container housing 200. The dirty liquid container 10 includes a connection structure to allow the dirty liquid container to be removably mounted to the body of a surface cleaning device. The connection structure also allows a user to easily remove the dirty liquid container to clean the dirty liquid and dirt therein.

[0033] Figure 3-Figure 4 An example of a separate dirty liquid container cap assembly 100 according to the present disclosure is shown, wherein Figure 3 The dirty liquid container cover assembly 100 is shown in an upright position, and Figure 4 The dirty liquid container cap assembly 100 is shown in a flat position, with an angle α ranging from approximately 0 to 10 degrees. The dirty liquid container cap assembly 100 can be inserted into and secured to the dirty liquid container housing 200. After the cleaning operation is completed, the dirty liquid container cap assembly 100 can be removed from the dirty liquid container housing 200 for cleaning by the user. The dirty liquid container cap assembly 100 includes a cap 101, which is disposed at one end of the dirty liquid container cap assembly 100. When assembled, the cap 101 can be positioned adjacent to the blower module 20.

[0034] The dirty liquid container lid assembly 100 includes a solid-liquid separation member 102. The solid-liquid separation member 102 is disposed on the side of the dirty liquid container lid assembly 100 opposite the lid body 101. The solid-liquid separation member 102 is configured to separate solid contaminants from the liquid in the dirty liquid and retain the separated solid contaminants. The solid-liquid separation member 102 is provided with holes or slits that allow the passage of dirty liquid. During cleaning operations, dirty liquid can pass through the solid-liquid separation member 102 through these holes or slits and enter the dirty liquid cavity, while solid contaminants cannot pass through these holes or slits, thereby retaining the solid contaminants on the solid-liquid separation member 102, thereby achieving solid-liquid separation. The contaminants retained on the solid-liquid separation member 102 can subsequently be cleaned by the user. In some embodiments, the solid-liquid separation member 102 extends along substantially the entire cross-section of the dirty liquid container 10. When assembled, the periphery of the solid-liquid separation member 102 may abut the inner wall of the dirty liquid container housing 200.

[0035] like Figure 3As shown in FIG, the dirty liquid container cover assembly 100 further includes a dirty liquid blocking member 110, which is disposed on a side of the solid-liquid separation member 102 away from the cover 101. The dirty liquid blocking member 110 may be spaced a certain distance from the solid-liquid separation member 102. The dirty liquid blocking member 110 is configured to mitigate the surge of dirty liquid in the dirty liquid container and block the surge of dirty liquid toward the cover 101 when the surface cleaning apparatus is in a flat position.

[0036] In some embodiments, the liquid barrier member 110 includes an extension 111 extending away from the solid-liquid separation member 102. The extension 111 is configured to reduce the kinetic energy of the liquid oscillation caused by the surface cleaning device being dragged back and forth when the liquid container 10 is in a flat position. The extension 111 is located at the periphery of the liquid barrier member 110 and is inclined toward the center of the liquid barrier member 110.

[0037] like Figure 3-Figure 4 As shown in FIG, the dirty liquid container housing 200 further includes a dirty liquid channel 203. In some embodiments, the dirty liquid channel 203 may be assembled to the dirty liquid container housing 200. In other embodiments, the dirty liquid channel 203 may be integrally formed with the dirty liquid container housing. Under the influence of the suction airflow generated by the fan module 20, dirty liquid can enter the dirty liquid container 10 through the dirty liquid channel 203. The dirty liquid channel 203 extends through the dirty liquid blocking member 110 and the solid-liquid separation member 102.

[0038] Also refer to Figure 3-Figure 4 The dirty liquid container cap assembly 100 further includes an airflow guiding member 104. The airflow guiding member 104 forms an airflow channel in fluid communication with the blower module 20, thereby extending the airflow path to the blower module 20. In some embodiments, the dirty liquid container cap assembly 100 further includes two airflow guiding members 104 located on either side of the dirty liquid channel 203 to further extend the airflow path.

[0039] Figure 5 FIG shows a cross-sectional view of the assembled dirty liquid container cover assembly 100 and the dirt container housing 200. Figure 5 As shown, the periphery of the dirty liquid blocking member 110 is adjacent to the dirty liquid container 10, and a gap is formed between the dirty liquid blocking member 110 and the inner wall of the dirty liquid container 10 to allow the dirty liquid to pass through. Figure 5In the figure, arrows of different forms are used to respectively illustrate the airflow path and the dirty liquid path, wherein the thinner arrows represent the path of the airflow, and the thicker arrows represent the path of the dirty liquid. The airflow drawn from the dirty liquid channel 203 travels along the first direction F1 toward the cover body 101, and is then blocked by the airflow blocking member 103, thereby changing direction to move in a second direction opposite to the first direction F1. The airflow is further guided by the airflow guiding member 104 located on one side. The airflow can thus bypass the dirty liquid channel 203 in a generally radial direction, and then be guided by the airflow guiding member 104 located on the other side to continue moving in the first direction F1, and then be sucked through the fan module. In some embodiments, a filter can also be provided on the airflow path to prevent solid dirt carried by the airflow from being entrained into the fan module, thereby causing damage. In some embodiments, the airflow blocking member 103 can be located between the cover body 101 and the dirty liquid channel 203.

[0040] The waste liquid sucked along with the airflow falls to the side of the solid-liquid separation member 102 due to gravity. The solid-liquid separated waste liquid passes through the solid-liquid separation member and falls to the waste liquid blocking member 110, then passes through the waste liquid blocking member 110 and enters and is stored in the waste liquid chamber 201.

[0041] Figure 6 The dirty liquid blocking member 110 and the solid-liquid separation member 102 are shown. In some embodiments, the dirty liquid blocking member 110 and the solid-liquid separation member 102 may have corresponding cross-sections, such as substantially similar cross-sections. The cross-section of the dirty liquid blocking member 110 may be slightly smaller than the cross-section of the solid-liquid separation member 102. Figure 6 As can be seen in FIG. 1 , the solid-liquid separation member 102 may include openings for allowing the passage of dirty liquid and holes or gaps for allowing the dirty liquid to flow.

[0042] Figure 7 The schematic diagram shows an assembled dirty liquid container, in which the dirty liquid container is in a flat position. At this time, the dirty liquid stored in the dirty liquid chamber 201 will generate a surge similar to a tidal phenomenon due to the user's back and forth dragging. If there is no dirty liquid blocking member, the dirty liquid in the surge may pass through the solid-liquid separation member 102 and be sucked into the fan module 20 due to the suction of the fan module. However, with the help of the dirty liquid blocking member 110, the surge of the dirty liquid in the dirty liquid container is slowed down and the surge of the dirty liquid toward the cover body 101 is blocked, thereby reducing the kinetic energy of the dirty liquid oscillation and preventing it from reaching the fan module. With the help of the extension 111 on the dirty liquid blocking member 110, the kinetic energy of the dirty liquid in the surge can be further reduced due to the interaction between the dirty liquid and the extension 111, so that almost no dirty liquid can reach the fan module.

[0043] In some embodiments, the dirty liquid container cover assembly further includes a dirty liquid detection point to detect the liquid level of the dirty liquid and trigger a protection function when the liquid level exceeds a liquid level threshold.

[0044] In implementing the claimed invention, those skilled in the art will be able to understand and implement variations of the disclosed embodiments by studying the drawings, the disclosure, and the appended claims. In the claims, the word "comprising" does not exclude other elements or steps, and the indefinite article "a" or "an" does not exclude a plurality.

[0045] The foregoing description has been described with reference to specific embodiments. However, the illustrative discussion above is not intended to be exhaustive or to limit the disclosure to the precise forms described. In light of the above teachings, many modifications and variations are possible. This will enable others skilled in the art to best utilize the technology and various embodiments with various modifications suitable for various applications.
