Description

Technical Field

[0001] This disclosure relates to a surface cleaning device processing method and a surface cleaning system. Background Technology

[0002] Existing floor cleaners clean floors with high-flow-rate cleaning fluid in a way that completely wets the floor to be cleaned. By wetting the hard floor surface, the cleaning head transfers dust from the floor into the cleaning fluid, which is then removed from the hard floor surface and stored in a recycling storage section as contaminated cleaning fluid.

[0003] Wet surface cleaners typically include: a cleaning solution reservoir for holding the cleaning solution; a recovery reservoir for collecting contaminants recovered from the cleaned floor; a motor-driven vacuum source to create a vacuum flow path from the cleaned floor to the recovery reservoir; a rechargeable battery to power the components; and a base station for charging and post-cleaning maintenance of the wet surface cleaner.

[0004] In existing wet surface cleaners, the agitator material causes a large amount of dirt to accumulate in the agitator after use. If not cleaned in time, the agitator will emit an odor, affecting the user experience.

[0005] However, in this field, the agitator is cleaned with water from a clean water tank, which is not very effective and the agitator may still emit an odor, resulting in a poor user experience. Summary of the Invention

[0080] 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.

[0081] 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.

[0082] 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.

[0083] 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.

[0084] 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.

[0085] 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.

[0086] 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.

[0087] Figure 1 This is a schematic diagram of the structure of a surface cleaning device according to one embodiment of the present disclosure.

[0088] like Figure 1 As shown, the surface cleaning device disclosed herein is used to clean the floor surface to be cleaned. Preferably, the surface cleaning device is capable of wet cleaning the floor surface to be cleaned and recovering the liquid after cleaning the floor surface to be cleaned back to the surface cleaning device.

[0089] like Figure 1 As shown, structurally, the surface cleaning device may include components such as a handle 100, a frame 200, a cleaning fluid storage unit 300, a recycling storage unit 400, a connecting part 500, and a floor brush assembly 600.

[0090] In use, the surface cleaning apparatus of this disclosure is configured to move on the floor surface to be cleaned, so as to perform wet cleaning on the floor surface to be cleaned by means of the floor brush assembly 600.

[0091] The handle 100 is used to operate the surface cleaning device. More specifically, on the one hand, the operator can control the posture of the surface cleaning device by operating the handle 100. For example, when the frame 200 of the surface cleaning device is in a tilted state (i.e., at an angle of approximately 60° to the surface to be cleaned) or in a roughly flat state (i.e., roughly parallel to the surface to be cleaned), the surface cleaning device is in cleaning mode. When the frame 200 of the surface cleaning device is in a vertical state, the surface cleaning device is in a stopped state, or when the surface cleaning device is in a base station, the frame 200 of the surface cleaning device is also in a roughly vertical state. On the other hand, physical buttons can be provided on the handle 100, so that the surface cleaning device can be controlled through these physical buttons, such as controlling the start and stop of the surface cleaning device, as well as controlling the liquid supply speed and suction power of the surface cleaning device, thereby improving the user experience of the surface cleaning device.

[0092] The handle portion 100 can be disposed at the upper end of the frame portion 200, thereby enabling the surface cleaning device to be operated by operating the handle portion 100. In this disclosure, the frame portion 200 is formed as the main load-bearing structure of the surface cleaning device, and the cleaning liquid storage portion 300 and the recovery storage portion 400 of the surface cleaning device can both be directly or simply fixed to the frame portion 200.

[0093] The cleaning fluid storage section 300 is formed in the shape of a box to store cleaning fluid. In one embodiment, the cleaning fluid can be purified water. Of course, those skilled in the art will know that the cleaning fluid storage section 300 can also store a mixture of purified water and cleaning agent, etc.

[0094] The frame portion 200 has a receiving space, and the cleaning fluid storage portion 300 can be disposed in the receiving space, such that a portion of the outer surface of the cleaning fluid storage portion 300 is formed as part of the outer surface of the surface cleaning device.

[0095] In this disclosure, the cleaning fluid storage unit 300 can be detached from the frame unit 200 and filled with cleaning fluid manually by the user; of course, the cleaning fluid storage unit 300 of this disclosure can also be filled with cleaning fluid through a cleaning fluid interface provided on the frame unit 200.

[0096] Furthermore, when the frame portion 200 is provided with a cleaning liquid interface, the cleaning liquid storage portion 300 can be disposed inside the frame portion 200. In this case, the cleaning liquid storage portion 300 is not formed as at least part of the outer surface of the surface cleaning device.

[0097] In this disclosure, in order to clean the surface to be cleaned, the cleaning liquid storage unit 300 is connected to the floor brush assembly 600 at least through a cleaning liquid pipeline, thereby providing the cleaning liquid to the floor brush assembly 600. On the one hand, the cleaning liquid can be used to directly clean the surface to be cleaned, and on the other hand, the cleaning liquid can be mixed with cleaning agents to form foam, and the surface to be cleaned can be cleaned through the foam.

[0098] like Figure 1 As shown, the frame portion 200 forms a receiving space, and the recycling storage portion 400 is detachably disposed on the frame portion 200 and located within the receiving space, so that when the recycling storage portion 400 contains a large amount of liquid, the user can remove the recycling storage portion 400, pour out the sewage inside, and clean up the solid waste. At this time, part of the outer surface of the recycling storage portion 400 forms part of the outer surface of the surface cleaning device.

[0099] In order to recover the liquid after cleaning the surface, the recovery storage unit 400 can be connected to the floor brush assembly 600 through the recovery pipe 401. Accordingly, the mixture of sewage and gas (dirt) can be recovered to the recovery storage unit 400 through the recovery pipe 401.

[0100] Accordingly, the surface cleaning equipment also includes a suction device (not shown in the figure), wherein the suction device is capable of generating negative pressure and providing this negative pressure to the recovery storage unit 400, thereby achieving forced flow of gas and wastewater within the recovery pipeline 401. In this disclosure, the gas discharged from the suction device can flow to the outside of the surface cleaning equipment through gaps on a portion of the outer surface of the surface cleaning equipment.

[0101] The frame portion 200 is connected to the floor brush assembly 600 via the connecting portion 500, thereby making the frame portion 200 pivotally connected to the floor brush assembly 600. In this disclosure, the frame portion 200 has at least two rotational degrees of freedom relative to the floor brush assembly 600, thereby enabling users to operate the surface cleaning equipment more conveniently.

[0102] The structure of the floor brush assembly 600 will be described in detail below with reference to the accompanying drawings.

[0103] Figure 2 This is a schematic diagram of the structure of a floor brush assembly according to one embodiment of the present disclosure.

[0104] In this disclosure, the floor brush assembly 600 may include components such as a frame 610, a suction nozzle 620, a stirring component 630, and a cover 640.

[0105] The frame portion 610 is configured to be connected to the frame portion 200 via a connecting portion 500, and the frame portion 610 is adaptable to move on the floor surface to be cleaned. For example, the frame portion 610 may include two rollers. The frame portion 610 can define a receiving cavity for the floor brush assembly, the receiving cavity being located in the front half of the floor brush assembly (with the direction of movement of the surface cleaning device when cleaning the surface to be cleaned as the front), so as to accommodate the agitator 630, which is also located in the front half of the floor brush assembly.

[0106] A suction nozzle 620 is formed on the frame portion 610. In this disclosure, the suction nozzle 620 is disposed adjacent to the stirring member 630 and located behind the stirring member 630. In this disclosure, the suction nozzle 620 is connected to the recovery pipeline 401 and forms the starting point of the recovery path.

[0107] The agitator 630 is configured to agitate the floor surface to be cleaned; that is, when the surface cleaning equipment is performing a cleaning operation or a self-cleaning operation, the agitator 630 can be driven by a motor to rotate, thereby enabling the agitator 630 to make frictional contact with the floor surface to be cleaned, and achieving cleaning of the floor surface. During the frictional contact between the agitator 630 and the floor surface to be cleaned, cleaning liquid can be supplied to the agitator 630, thereby achieving wet cleaning of the floor surface to be cleaned.

[0108] The cover 640 is disposed on the frame portion 610 and configured to partially surround the stirring member 630; in one embodiment, the cover 640 is also formed as part of the receiving cavity. In other words, the cover 640 and the frame portion 610 together form the aforementioned receiving cavity.

[0109] Figure 3 This is a front view structural schematic diagram of a floor brush assembly according to one embodiment of the present disclosure. Figure 4 This is a bottom view of a floor brush assembly according to one embodiment of the present disclosure. Figure 5 yes Figure 4 Enlarged schematic diagram of part A.

[0110] More specifically, such as Figure 4As shown, the cover 640 has at least a first edge and a second edge, wherein the second edge of the cover 640 is the edge close to the frame portion 610, and the first edge of the cover 640 is the edge away from the frame portion 610, thereby forming the first edge as a free end.

[0111] More preferably, the first edge is positioned above the horizontal plane passing through the axis of rotation of the agitator 630, thereby providing a reasonable height between the first edge and the surface to be cleaned, increasing the coverage area of ​​the foam sprayed by the nozzle.

[0112] The first edge has a generally planar shape, and the nozzle 650 is mounted on the cover 640 and located at the center of the first edge, so that the nozzle 650 is centered in the lateral direction (the lateral direction is the horizontal direction perpendicular to the front-back direction), so that the nozzle 650 can spray foam in a fan-shaped radial pattern from the center to the edge.

[0113] Figure 6 This is a schematic diagram of the nozzle structure according to one embodiment of the present disclosure. Figure 7 This is a cross-sectional structural schematic diagram of a nozzle according to one embodiment of the present disclosure.

[0114] like Figure 6 and Figure 7 As shown, the nozzle 650 can supply cleaning foam generated by the foam generator 800 to the surface to be cleaned. That is, the foam generator 800 can generate high-pressure foam, and this high-pressure foam is ejected at high speed from the nozzle 650, thereby giving the cleaning foam a large coverage area.

[0115] Structurally, the nozzle 650 includes a first body 651 and a second body 652 connected to each other; wherein the first body 651 and the second body 652 can be integrally formed or separately formed and installed or fixed together.

[0116] In this disclosure, such as Figure 6 and Figure 7 As shown, the first body 651 is formed as a hemispherical thin-walled part, thereby forming a hemispherical buffer cavity inside the first body 651. That is, the outer surface of the first body 651 is a hemispherical surface, and correspondingly, the inner surface of the first body 651 is a hemispherical surface, thereby making the first body 651 have a generally uniform wall thickness.

[0117] At least a portion of the second body 652 is formed in a cylindrical shape; for example, the end of the second body 652 connected to the first body 651 is formed in a generally cylindrical shape. Preferably, in this disclosure, the outer diameter (diameter) of the cylindrical portion of the second body 652 is the same as the diameter of the outer surface of the first body 651.

[0118] The second body 652 includes a conveying channel for conveying cleaning foam, and the conveying channel is in communication with the hemispherical buffer cavity; as shown. Figure 7 As shown, the conveying channel is formed in a cylindrical shape, and the inner diameter of the conveying channel is the same as the diameter of the inner surface of the first body 651, so that the cleaning foam has the least possible resistance during the conveying process.

[0119] like Figure 6 As shown, the nozzle 650 also includes a cut 653 through which cleaning foam is supplied to the surface to be cleaned; in a specific embodiment, the cut 653 is configured to penetrate the first body 651 laterally and communicate with the hemispherical buffer cavity, so that the cleaning foam forms a fan-shaped radiating surface after leaving the cut 653.

[0120] In other words, when processing the cut 653 of the first body 651, a groove of a certain width and depth can be cut from the apex of the first body 651 toward the center of the sphere. When installing the nozzle 650 onto the cover 640, the cut 653 can be kept in a transverse direction or approximately transverse direction.

[0121] In a more preferred embodiment, at least a portion of the cut 653 extends into the second body 652, that is, at least a portion of the second body 652 is formed with a groove that is part of the cut 653.

[0122] At this time, the inner diameter of the conveying channel is smaller than the projected length of the cut 653 on the cross-section of the conveying channel, thereby enabling the cut 653 to have a maximized foam radiation area.

[0123] In this disclosure, such as Figure 7 As shown, the conveying channel includes a circular channel outlet, and the projection center of the cut 653 at the circular channel outlet passes through the center of the circular channel outlet, so that the cut 653 is centrally located in the first body 651 and the second body 652.

[0124] When the foam generator 800 operates with an air flow rate of 8.6 L / min and a cleaning agent flow rate of 65 ml / min, the angle of the fan-shaped radiating surface is 10°-160°.

[0125] The diameter of the conveying channel is 2-3 mm, and correspondingly, the diameter of the hemispherical buffer cavity is the same as the diameter of the conveying channel. In this case, the width W of the cut 653 is 0.2-0.4 mm, meaning that the width of the cut 653 is between 6% and 20% of the diameter of the conveying channel.

[0126] Furthermore, the depth L of the portion of the cut 653 located within the second body 652 is 0.1-0.3 mm; that is, the depth of the portion of the cut 653 located within the second body 652 is between 3% and 15% of the diameter of the conveying channel.

[0127] like Figure 6 and Figure 7 As shown, the nozzle 650 further includes a first mounting portion 654, which is used to connect to the foam generator 800. In one embodiment, the first mounting portion 654 is a plurality of annular barbed structures formed on the outer surface of the second body 652. In this case, the nozzle 650 can be connected to the foam supply pipeline by inserting the second body 652 into the interior of the foam supply pipeline. The other end of the foam supply pipeline can be connected to the foam outlet of the foam generator 800. Thus, the foam generator 800 and the nozzle 650 together form a foam distributor, which is configured to dispense foam to at least one of the stirring element and / or the surface of the floor to be cleaned.

[0128] More preferably, the nozzle 650 further includes a second mounting portion 655, which is formed as an ear extending outward from the outer surface of the second body 652. Accordingly, the second mounting portion 655 is used to fix the nozzle 650 to the cover 640 of the floor brush assembly 600.

[0129] See again Figure 5 When the floor brush assembly 600 moves along the surface (plane) to be cleaned, the nozzle 650 is perpendicular or approximately perpendicular to the surface to be cleaned. In other words, the plane where the cut 653 is located is perpendicular or approximately perpendicular to the surface to be cleaned. Preferably, the distance between the nozzle 650 and the surface to be cleaned is approximately 15-30 mm, which may vary depending on the length of the agitator 630.

[0130] Figure 8 A schematic diagram of the internal structure of a floor brush assembly according to one embodiment of the present disclosure is shown.

[0131] like Figure 8As shown, the floor brush assembly may further include a foaming agent storage section 670 for storing foaming agent. Furthermore, the foaming agent stored in the foaming agent storage section 670 can be mixed with air by the aforementioned foam generator 800 to generate cleaning foam. In one embodiment, the foaming agent may be a cleaning agent or a liquid containing a surfactant.

[0132] The frame portion 610 further defines a receiving chamber in which the foaming agent storage portion 670 is disposed. Alternatively, in this disclosure, the foaming agent storage portion 670 may also be disposed in the frame portion 200.

[0133] like Figure 8 As shown, the floor brush assembly 600 also has a sealed box 694 in its housing. Electronic components such as a control circuit board can be installed in the sealed box 694, which facilitates the connection between the control circuit board and the foam generator 800, the cleaning liquid pump 680, and the defoamer pump 693.

[0134] Figure 9 A schematic diagram of a surface cleaning apparatus according to one embodiment of the present disclosure is shown.

[0135] like Figure 9 As shown, the foaming agent storage unit 670 is connected to the nozzle 650 via the foam generator 800, thereby allowing the foaming agent stored in the foaming agent storage unit 670 to generate clean foam via the foam generator, which is then supplied to the nozzle 650 and sprayed out from the nozzle 650.

[0136] More preferably, the floor brush assembly 600 may further include a cleaning fluid pump 680, the cleaning fluid storage unit 300 is connected to the cleaning fluid pump 680, and the cleaning fluid pump 680 is connected to the water outlet strip 690 (also referred to as a liquid distributor). This allows the cleaning fluid stored in the cleaning fluid storage unit 300 to be pressurized by the cleaning fluid pump 680 and supplied to the water outlet strip 690. The pressurized cleaning fluid can be sprayed out from the water outlet strip 690, thereby providing the cleaning fluid to the agitator 630 and / or the surface to be cleaned near the agitator 630.

[0137] In this disclosure, the water outlet strip 690 is arranged along the length direction of the agitator 630 and has at least one water outlet; preferably, there are multiple water outlets, and these water outlets are arranged in at least one row along the length direction of the agitator 630. In this disclosure, the water outlet strip 690 can be arranged behind the agitator 630, so that when the agitator 630 rotates and cleans the surface to be cleaned, the cleaning liquid can be more fully wetted and dispersed on the surface of the agitator 630, thereby improving the cleaning effect on the surface to be cleaned.

[0138] like Figure 4 As shown, the floor brush assembly 600 may further include a squeegee 691, which is disposed on the frame portion 610 and located below the frame portion 610. Preferably, the squeegee 691 is disposed behind the contact area between the agitator 630 and the surface to be cleaned, thereby enabling timely collection of wastewater and other contaminants on the surface to be cleaned and sucked into the recycling storage section 400 through the suction nozzle 620.

[0139] In this disclosure, the floor brush assembly 600 further includes a defoamer storage section 692 for storing defoamer. That is, when the surface cleaning equipment of this disclosure is in use, a mixture of wastewater, foam, and air enters the recovery storage section 400. If this foam is not removed in time, it will accumulate in the recovery storage section 400 and may even overflow to the outside, affecting the service life of the suction device. Accordingly, in this disclosure, the defoamer provided by the defoamer storage section 692 can reduce the surface tension of the liquid in the recovery storage section 400, reduce the amount of foam in the recovery storage section 400, and even remove all the foam from the recovery storage section 400.

[0140] The defoamer storage section 692 can be disposed in the receiving chamber of the frame section 610. In this disclosure, by disposing of the foaming agent storage section 670 and the defoamer storage section 692 in the frame section 610, the center of gravity of the entire surface cleaning device can be lowered, making it easier for the user to operate the surface cleaning device.

[0141] In this disclosure, the defoamer storage unit 692 is connected to the defoamer pump 693, which can supply defoamer to components such as the recovery pipeline 401 or the suction nozzle 620, thereby delivering the defoamer to the recovery storage unit 400 through suction. Alternatively, the defoamer pump 693 can also be directly connected to the recovery storage unit 400 to directly supply defoamer to the recovery storage unit 400.

[0142] Of course, the defoamer storage unit 692 can also be directly connected to the recovery pipeline 401 or the nozzle 620 via the defoamer pipeline.

[0143] Figure 10 A schematic diagram of the frame portion according to one embodiment of the present disclosure is shown.

[0144] like Figure 10As shown, the frame portion 610 forms the aforementioned suction nozzle 620. The suction nozzle 620 includes a transition cavity, one end of which is formed as an opening, thereby allowing a mixture of wastewater, gas, and foam to enter the transition cavity through the opening; correspondingly, the other end of the transition cavity is connected to a recovery pipe 401, so that the mixture of wastewater, gas, and foam can be recovered through the recovery pipe 401.

[0145] In one embodiment, the cross-section of the transition cavity (i.e., the cross-section perpendicular to the flow direction of the mixture) can be square, and its area can be gradually reduced, thereby facilitating the connection between the transition cavity and the recovery pipeline 401.

[0146] The nozzle 620 has a pipe connection 621 on its side wall. The defoamer storage unit 692 is connected to one end of the defoamer pipeline, and the other end of the defoamer pipeline is connected to the pipe connection 621, thereby allowing fluid communication between the nozzle 620 and the defoamer storage unit 692. In a preferred embodiment, the pipe connection 621 is located on the upper wall of the nozzle 620, which facilitates the installation and disassembly of the defoamer pipeline.

[0147] At this time, the aforementioned defoamer pump 693 can be installed in the defoamer pipeline, so that the defoamer is drawn out from the defoamer storage unit 692 and then discharged to the nozzle 620 by positive pressure.

[0148] In another embodiment, instead of a defoamer pump 693, the defoamer in the defoamer storage unit 692 is drawn into the nozzle 620 by negative pressure suction. Correspondingly, a solenoid valve is provided on the defoamer pipeline, which opens when negative pressure is generated in the nozzle 620.

[0149] In this disclosure, the defoamer storage section 692 also includes an open hole to allow air to enter the defoamer storage section 692 through the open hole, thereby balancing the internal and external pressure difference of the defoamer storage section 692 and facilitating the suction of the defoamer pump 693 or the extraction under negative pressure.

[0150] The floor brush assembly disclosed herein also includes a controller, which may be an electronic component disposed on the control circuit board. The controller is used to dispense defoamer into the recovery storage unit before the mixture reaches it, thereby enabling the foam to be eliminated as quickly as possible when it is drawn into the recovery storage unit.

[0151] In other words, when cleaning the surface to be cleaned with foam, the presence of surfactants in the foam will cause the recovery storage unit 400 to be filled with a large amount of foam. This affects the water level detection of the recovery storage unit 400 on the one hand, and the gas-solid-liquid separation function of the recovery storage unit 400 on the other hand.

[0152] Accordingly, if defoamer is present inside the recycling storage unit 400, it is not necessary to add defoamer to the recycling storage unit 400, or only a small amount of defoamer needs to be added. In this case, the addition of defoamer can be initiated by whether the recycling storage unit 400 has been removed from the surface cleaning equipment. For example, after the recycling storage unit 400 has been removed from the surface cleaning equipment, the user may empty the wastewater and clean the recycling storage unit 400; after the cleaned recycling storage unit 400 is reinstalled into the surface cleaning equipment, defoamer needs to be added to the inside of the recycling storage unit 400 as soon as possible.

[0153] During a cleaning operation, the controller can activate the defoamer pump or solenoid valve at least once, with each activation lasting a predetermined time, such as 1 second, to complete the addition of the defoamer.

[0154] The structure of the foam generator will be described in detail below with reference to the accompanying drawings.

[0155] Figure 11 This is a schematic diagram of a foam generator according to one embodiment of the present disclosure.

[0156] like Figure 11 The present disclosure provides a foam generator 800, which includes a gas pump 810, a liquid pump 820, and a mixing chamber 830.

[0157] The gas pump 810 is in communication with the atmosphere to draw gas directly from the atmosphere and can supply gas to the mixing chamber 830, for example, to supply gas at a high flow rate.

[0158] In one embodiment, the gas pump 810 can be driven by a drive device 840 to generate high-velocity gas. That is, the drive device 840 is connected to the gas pump 810 in a driving connection, and when the drive device 840 is rotating, it enables the gas pump 810 to be in a working state and continuously output high-velocity gas.

[0159] The gas pump 810 can be a centrifugal pump, plunger pump, impeller pump, diaphragm pump, etc. This disclosure does not limit the type of gas pump 810, as long as the gas pump 810 can generate high-pressure gas.

[0160] Figure 12 and Figure 13This is a schematic diagram of the structure of a liquid pump according to one embodiment of the present disclosure.

[0161] like Figure 12 and Figure 13 As shown, the liquid pump 820 is connected to the supply tank and is used to supply liquid.

[0162] The liquid pump 820 is preferably a peristaltic pump; Figure 13 The diagram shows the structure of a fixed peristaltic pump, in which a squeezing assembly 821 can be driven to rotate. When the squeezing assembly 821 rotates, it squeezes the hose 822, causing the hose 822 to deform and enabling the delivery of liquid within the hose 822.

[0163] Those skilled in the art will understand that the peristaltic pump is merely a preferred implementation; other liquid pumps, such as impeller pumps and plunger pumps, may also be selected in this disclosure.

[0164] Figure 14 This is a schematic diagram of the structure of a mixing chamber according to one embodiment of the present disclosure.

[0165] like Figure 11 As shown, the gas pump 810 and the liquid pump 820 are both connected to the mixing chamber 830, enabling the mixing chamber 830 to receive the gas generated by the gas pump 810 and the liquid generated by the liquid pump 820; and to mix the gas and liquid in the mixing chamber 830 to generate foam.

[0166] In a specific structure, such as Figure 14 As shown, the mixing chamber 830 includes structures such as a first inlet 831, a second inlet 832, and a mixing chamber 833.

[0167] The first inlet 831 is used for liquid inlet; in this disclosure, the first inlet 831 can be connected to a liquid pump 820; the second inlet 832 is used for gas inlet; for example, the second inlet 832 is connected to a gas pump. The mixing chamber 833 is used for mixing the liquid and gas, wherein the first inlet 831 and the second inlet 832 form a preset angle; in a preferred embodiment, the first inlet 831 and the second inlet 832 are vertically distributed, for example... Figure 14 As shown, the first inlet 831 is generally horizontal and the second inlet 832 is generally vertical. In this case, the second inlet 832 is perpendicular or approximately perpendicular to the flow direction of the liquid in the mixing chamber 833. This arrangement is more conducive to mixing gas into the liquid, thereby forming abundant foam.

[0168] In a preferred embodiment, the mixing chamber 830 further includes a columnar filter 834 comprising one or more elongated filter holes through which the gas and liquid mixture is conveyed to and discharged from a foam outlet.

[0169] In this disclosure, the speed of foam output can be controlled by adjusting the rotational speed of the drive device.

[0170] The foam generator 800 disclosed herein also includes a drive unit 840 for driving the gas pump 810 and the liquid pump 820, thereby enabling the gas pump 810 and the liquid pump 820 to be in an operational state. In a preferred embodiment, the gas pump 810 and the liquid pump 820 are driven by the same drive unit 840, and the gas pump 810 and the liquid pump 820 are located on the same side of the drive unit 840.

[0171] Therefore, by using a single drive device 840 to simultaneously drive both the gas pump 810 and the liquid pump 820, and by incorporating a peristaltic pump, the problem of solution adhesion and non-dispensing can be solved. The gas pump is a diaphragm pump, achieving a small volume and high flow rate, resulting in a small overall pump size and low cost. Furthermore, the separate configuration of the gas pump 810 and the liquid pump 820 significantly increases the fluid flow rate, thus enabling the foam generator of this disclosure to significantly improve fluid flow rate.

[0172] Figure 15 This is a flowchart of a surface cleaning apparatus processing method according to one embodiment of the present disclosure.

[0173] like Figure 15 As shown, the surface cleaning equipment processing method of this disclosure can clean the agitator 630 of the surface cleaning equipment. That is, the surface cleaning equipment processing method of this disclosure can remove dirt from the agitator 630 during the cleaning operation, thereby improving the cleaning efficiency; or after the cleaning operation is completed, remove the dirt from the agitator 630 so that the agitator 630 will not emit odor.

[0174] Specifically, the processing method of the surface cleaning equipment includes: the surface cleaning equipment receiving a signal to perform foam treatment on the agitator 630 of the surface cleaning equipment; determining whether the surface cleaning equipment is docked on the tray; when the surface cleaning equipment is not docked on the tray, docking the surface cleaning equipment on the tray and then initiating the request to perform foam treatment on the agitator 630 of the surface cleaning equipment; when the surface cleaning equipment is docked on the tray, performing a self-check on the surface cleaning equipment to obtain the current state of the surface cleaning equipment; determining whether the surface cleaning equipment meets preset conditions based on the current state of the surface cleaning equipment; when the surface cleaning equipment meets the preset conditions, allowing foam treatment on the agitator 630 of the surface cleaning equipment; wherein, the surface cleaning equipment is determined to meet the preset conditions when the following conditions are met: the power of the surface cleaning equipment is greater than a preset value, the cleaning liquid storage section 300 of the surface cleaning equipment is located on the surface cleaning equipment, the recycling storage section of the surface cleaning equipment is located on the surface cleaning equipment, the foaming agent storage section is located on the surface cleaning equipment, the amount of foaming agent in the foaming agent storage section is greater than or equal to a preset value, and the amount of liquid in the recycling storage section is less than or equal to a certain preset value.

[0175] The following will provide a detailed description of the treatment methods of the aforementioned surface cleaning equipment.

[0176] In this disclosure, a self-cleaning button can be provided on the handle 100 of the surface cleaning device, and a signal for foam treatment of the stirring component 630 of the surface cleaning device can be generated by triggering the self-cleaning button. Furthermore, when the signal for foam treatment of the stirring component 630 of the surface cleaning device is generated, the surface cleaning device can obtain the signal for foam treatment of the stirring component 630 of the surface cleaning device.

[0177] Of course, a signal for foam treatment of the agitator 630 of the surface cleaning equipment can also be generated by operating an APP or other means. The method of generating this signal will not be described in detail in this disclosure.

[0178] When the surface cleaning device receives a signal to perform foam treatment on its agitator 630, it needs to determine whether the surface cleaning device is docked at the tray (or base station). In other words, the surface cleaning device can only process the agitator 630 when it is docked at the tray. Otherwise, the self-cleaning button may be erroneously activated, incorrectly generating a signal to perform foam treatment on the agitator 630. In this case, foam treatment on the agitator 630 is not permitted. Furthermore, if the surface cleaning device is not docked at the tray, after docking it, the self-cleaning button is triggered again, generating another signal to perform foam treatment on the agitator 630, thus re-initiating the request to perform foam treatment on the agitator 630.

[0179] Furthermore, when the surface cleaning equipment is parked on the tray, it performs a self-check to obtain the current status of the surface cleaning equipment; based on the current status of the surface cleaning equipment, it determines whether the surface cleaning equipment meets the preset conditions.

[0180] When the surface cleaning equipment meets the preset conditions, foam treatment is allowed on the agitator 630 of the surface cleaning equipment; correspondingly, when the surface cleaning equipment does not meet the preset conditions, foam treatment is not allowed on the agitator 630 of the surface cleaning equipment.

[0181] More specifically: The surface cleaning equipment is deemed to meet preset conditions when the following conditions are met: the power of the surface cleaning equipment is greater than a preset value, the cleaning liquid storage section 300 of the surface cleaning equipment is located in the surface cleaning equipment, the recycling storage section of the surface cleaning equipment is located in the surface cleaning equipment, the foaming agent storage section is located in the surface cleaning equipment, the amount of foaming agent in the foaming agent storage section is greater than or equal to a preset value, and the amount of liquid in the recycling storage section is less than or equal to a certain preset value.

[0182] In this disclosure, since the surface cleaning equipment's agitator 630 needs to be rotated during processing, and also needs to provide foam and pump out wastewater, the surface cleaning equipment's battery level needs to be kept above a preset value (e.g., 20%). On the other hand, when the surface cleaning equipment's battery level is below the preset value, the user is prompted to charge the surface cleaning equipment. When the surface cleaning equipment is charged and its battery level is above the preset value, the self-cleaning button can be triggered again to generate a signal for foam treatment of the surface cleaning equipment's agitator 630, and initiate a request for foam treatment of the surface cleaning equipment's agitator 630.

[0183] During the processing of the agitator 630 of the surface cleaning equipment, it is necessary to provide cleaning liquid or cleaning foam to the agitator 630. Therefore, it is essential to ensure that the cleaning liquid storage unit 300 of the surface cleaning equipment is present. Conversely, if the cleaning liquid storage unit 300 is not present, the user is prompted to install the cleaning liquid storage unit 300 onto the frame 200 of the surface cleaning equipment. After the user installs the cleaning liquid storage unit 300 onto the surface cleaning equipment, the self-cleaning button can be triggered again to generate a signal for foam treatment of the agitator 630 of the surface cleaning equipment, initiating a request for foam treatment of the agitator 630 of the surface cleaning equipment.

[0184] On the other hand, when the cleaning liquid storage unit 300 of the surface cleaning device is in use, it is also necessary to detect the amount of cleaning liquid in the cleaning liquid storage unit 300 and determine whether the amount of cleaning liquid is greater than a preset value. Specifically, determining that the surface cleaning device meets the preset conditions also includes: the amount of cleaning liquid in the cleaning liquid storage unit 300 is greater than a preset value (e.g., 20%); when the amount of cleaning liquid in the cleaning liquid storage unit 300 is less than or equal to the preset value, the user is reminded to add cleaning liquid to the cleaning liquid storage unit 300, and after adding cleaning liquid and the amount of cleaning liquid is greater than the preset value, the self-cleaning button can be triggered again to generate a signal for foam treatment of the agitator 630 of the surface cleaning device and initiate a request for foam treatment of the agitator 630 of the surface cleaning device.

[0185] During the processing of the agitator 630 of the surface cleaning equipment, it is necessary to collect the dirt and liquid after self-cleaning into the collection and storage unit 400. Therefore, the collection and storage unit 400 must be located within the surface cleaning equipment. Conversely, if the collection and storage unit 400 is not located within the surface cleaning equipment, the user is prompted to install the collection and storage unit 400 onto the frame 200 of the surface cleaning equipment. After the user installs the collection and storage unit 400 into the surface cleaning equipment, the self-cleaning button can be triggered again to generate a signal for foam treatment of the agitator 630 of the surface cleaning equipment, initiating a request for foam treatment of the agitator 630 of the surface cleaning equipment.

[0186] On the other hand, when the recovery storage unit 400 of the surface cleaning equipment is in use, it is also necessary to detect the amount of liquid in the recovery storage unit 400 and determine whether the amount of cleaning liquid is less than or equal to a certain preset value (e.g., 50%). In other words, the requirement to suck up dirt and liquid can only be met when the amount of liquid in the recovery storage unit 400 is low. When the amount of liquid in the recovery storage unit 400 is greater than a certain preset value, the user is reminded to clean the recovery storage unit 400 and empty the liquid. After the user cleans the recovery storage unit 400 and the amount of liquid in the recovery storage unit 400 is less than or equal to a certain preset value, the self-cleaning button can be triggered again to generate a signal for foam treatment of the agitator 630 of the surface cleaning equipment and initiate a request for foam treatment of the agitator 630 of the surface cleaning equipment.

[0187] In this disclosure, since cleaning foam needs to be provided to the agitator 630 of the surface cleaning equipment when processing it, it is necessary to ensure that the foaming agent storage unit 670 is located in the surface cleaning equipment. On the other hand, when the foaming agent storage unit 670 is not located in the surface cleaning equipment, the user is prompted to install the foaming agent storage unit 670 in the surface cleaning equipment. After the user installs the foaming agent storage unit 670 in the surface cleaning equipment, the self-cleaning button can be triggered again to generate a signal for foam treatment of the agitator 630 of the surface cleaning equipment and initiate a request for foam treatment of the agitator 630 of the surface cleaning equipment.

[0188] On the other hand, when the foaming agent storage unit 670 of the surface cleaning equipment is in use, it is also necessary to detect the amount of foaming agent in the foaming agent storage unit 670 and determine whether the amount of foaming agent is greater than a preset value (20%). When the amount of foaming agent in the foaming agent storage unit 670 is less than or equal to the preset value, the user is reminded to add foaming agent to the foaming agent storage unit 670. After adding foaming agent and the amount of foaming agent is greater than the preset value, the self-cleaning button can be triggered again to generate a signal for foam treatment of the agitator 630 of the surface cleaning equipment and initiate a request for foam treatment of the agitator 630 of the surface cleaning equipment.

[0189] In this disclosure, determining that the surface cleaning device meets the preset conditions further includes: the agitator 630 meets the predetermined conditions; in a specific embodiment, the agitator 630 meeting the predetermined conditions includes at least: the agitator 630 is located on the surface cleaning device, the agitator 630 is in the correct position on the tray, and the agitator 630 can be driven to rotate.

[0190] In a preferred embodiment, foam treatment of the agitator 630 of the surface cleaning device includes foam self-cleaning of the agitator 630, thereby improving the self-cleaning effect of the agitator 630.

[0191] More specifically: Foam self-cleaning of the agitator 630 of the surface cleaning device includes: controlling the foam generator of the surface cleaning device to provide cleaning foam to the agitator 630 at a preset flow rate for a preset time, such that at least a portion of the agitator 630 is covered by the cleaning foam; in this disclosure, the provision of cleaning foam to the agitator 630 can be done automatically or manually. When done manually, the user can trigger the foam supply button to provide cleaning foam; and after providing an appropriate amount of cleaning foam, the user can trigger the foam supply button again or trigger the stop foam supply button to stop the supply of cleaning foam. In this disclosure, when the surface cleaning device includes a foam supply button, triggering only the self-cleaning button performs cleaning liquid treatment (cleaning liquid self-cleaning) on ​​the agitator of the surface cleaning device; correspondingly, when the self-cleaning button and the foam supply button are triggered simultaneously, or when the self-cleaning button is triggered first and the foam supply button is triggered within a preset time, a signal for foam treatment of the agitator of the surface cleaning device is generated, and foam self-cleaning is performed.

[0192] Figure 16 This is a schematic diagram of the structure of a tray according to one embodiment of the present disclosure.

[0193] like Figure 16 As shown, the tray of this disclosure can be used for docking surface cleaning equipment; in particular, the tray includes a receiving groove 901 capable of accommodating a stirring component 630 of the surface cleaning equipment, which can be disposed within the receiving groove 901 during self-cleaning of the stirring component 630. At this time, cleaning foam can also be provided to the receiving groove 901, thereby causing at least a portion of the stirring component 630 to be covered by the cleaning foam.

[0194] In this disclosure, when cleaning foam is provided, the agitator 630 can be controlled to rotate so that the periphery of the agitator 630 is evenly coated with cleaning foam. That is, while the foam generator of the surface cleaning device provides cleaning foam to the agitator 630, the agitator 630 is controlled to rotate for a first preset time; when the foam generator does not provide cleaning foam to the agitator 630, the agitator 630 is controlled to rotate for a second preset time.

[0195] Then, the suction device is activated to draw the cleaning foam and the cleaning liquid converted from the cleaning foam around the agitator 630 into the recovery and storage section 400 of the surface cleaning equipment.

[0196] More preferably, controlling the rotation of the agitator 630 for a first preset time includes: cyclically performing the following steps at least once within the first preset time: controlling the agitator 630 to rotate in a first direction, and / or controlling the agitator 630 to rotate in a second direction; more preferably, cyclically performing the following steps at least once within a second preset time: controlling the agitator 630 to rotate in the first direction, and / or controlling the agitator 630 to rotate in the second direction, thereby making the agitator 630 cleaner.

[0197] In a preferred embodiment, when the foaming process of the agitator 630 of the surface cleaning device begins, the battery charging circuit is automatically shut off, thereby preventing the rechargeable battery of the surface cleaning device from charging and discharging simultaneously, thus improving the service life of the rechargeable battery.

[0198] In this disclosure, after foam treatment of the agitator 630 of the surface cleaning equipment, a self-cleaning program for the cleaning liquid of the surface cleaning equipment is automatically initiated to self-clean the agitator 630. That is, after foam treatment of the agitator 630, foam residue will remain on the agitator 630. Based on this, this disclosure achieves a cleaner agitator 630 by performing self-cleaning with the cleaning liquid.

[0199] When the agitator 630 is self-cleaned with cleaning fluid, the agitator 630 is controlled to rotate forward and reverse for a preset time. This allows the residual foam on the tray to be removed by the reverse rotation of the agitator 630, and further, the foam is sucked into the recycling storage unit 400.

[0200] In one embodiment, after the agitator 630 of the surface cleaning device is self-cleaned with cleaning fluid, the agitator 630 of the surface cleaning device is then subjected to heat drying treatment, thereby ensuring that the self-cleaned agitator 630 is in a dry state. At this time, even if the surface cleaning device is not used for a long time, no odor will be generated.

[0201] Specifically, the tray of this disclosure includes a hot drying fan, which, when started, generates a gas flow path to the agitator 630; and a heating component is provided inside the gas flow path to heat the air in the gas flow path, thereby enabling the tray of this disclosure to provide hot air for hot drying to the agitator.

[0202] At this time, the hot drying process of the agitator 630 of the surface cleaning equipment includes: controlling the start of the hot drying fan; controlling the start of the heating component and controlling the rotation of the agitator 630; after a preset time; controlling the stop of the agitator 630, controlling the stop of the heating component, and controlling the shut-off of the hot drying fan.

[0203] In addition, when the agitator 630 is performing foam treatment, the foam treatment will automatically stop when the surface cleaning equipment is removed from the tray, thereby preventing accidents from happening to the surface cleaning equipment.

[0204] In this disclosure, the surface cleaning equipment and tray described above can form a surface cleaning system, which can be used to perform the processing method of the surface cleaning equipment described above.

[0205] In this disclosure, when the surface cleaning device is docked on a tray, the tray is at least capable of charging the surface cleaning device.
