Description

[0001] This application is a divisional application of a utility model application entitled "Cleaning Equipment", with parent application number "202422169682.0" and parent application date of September 4, 2024. Technical Field

[0002] This disclosure relates to the field of steam equipment, and more specifically to a cleaning device. Background Technology

[0003] With the development of social productivity, people's living standards have continuously improved. With their material needs met, people have begun to use various tools to reduce labor and improve their quality of life at home, leading to the emergence of household cleaning equipment. Among the many household cleaning devices, steam floor scrubbers, which combine vacuuming and steam cleaning capabilities, have gained popularity among consumers due to their powerful floor cleaning abilities.

[0004] Steam floor scrubbers are effective at cleaning grease and stains on floors, and can effectively help users clean kitchen floors and perform simple disinfection. However, current steam floor scrubbers on the market suffer from serious steam liquefaction and dripping issues. The steam sprayed onto the roller brush or floor has a high liquid content, making it easy for watermarks to remain on the floor. The cleaned floor is overly wet and difficult to dry, resulting in a poor user experience. Furthermore, the liquefied condensate produced during steam transmission tends to accumulate at the steam nozzles. On the one hand, this can cause condensate to drip from the steam nozzles after the machine is turned off, leaving residual water on the floor. On the other hand, when the user restarts the steam function, the steam nozzles will first spray out the residual condensate from the steam channel, leaving the floor wet. Utility Model Content

[0025] The floor brush housing is provided with a flow guide, and the liquid separated by the gas-liquid separation module is configured to flow sequentially through the drain port, the drain channel and the flow guide to the roller brush.

[0026] According to a fourth aspect of this disclosure, a cleaning device is provided, including a floor brush assembly, the floor brush assembly comprising:

[0027] Floor brush housing;

[0028] A roller brush, rotatably connected to the floor brush housing, and configured to clean a work surface;

[0029] A roller brush cover assembly includes a roller brush cover body and a steam output section.

During the cleaning process, the steam output unit can spray steam onto the work surface, thereby improving the cleaning and sterilization effects. Due to the low liquid content in the steam, liquefaction and dripping are effectively avoided, allowing the cleaned work surface to dry quickly and preventing watermarks from remaining, thus improving the user experience. Furthermore, the liquid flowing from the drain port flows into the drain channel under gravity and then to the guide component, which in turn guides it to the roller brush, preventing the liquid from dripping onto the ground and leaving water stains.

[0051] Various exemplary embodiments of the present disclosure will now be described in detail with reference to the accompanying drawings. It should be noted that, unless otherwise specifically stated, the relative arrangement, numerical expressions, and values ​​of the components and steps set forth in these embodiments do not limit the scope of the present disclosure.

[0052] The following description of at least one exemplary embodiment is merely illustrative and is in no way intended to limit this disclosure or its application or use.

[0053] Techniques, methods, and equipment known to those skilled in the art may not be discussed in detail, but where appropriate, such techniques, methods, and equipment should be considered part of the specification.

[0054] It should be noted that similar labels and letters in the following figures indicate similar items; therefore, once an item is defined in one figure, it does not need to be discussed further in subsequent figures.

[0055] In this article, terms such as "up," "down," "front," "back," "left," and "right" are used only to indicate the relative positional relationship between related parts, rather than to define the absolute position of these related parts.

[0056] In this article, "first," "second," etc., are used only to distinguish one another, and not to indicate degree of importance, order, or prerequisite for each other.

[0057] In this document, terms such as “equal” and “same” are not strict mathematical and / or geometric limitations, but also include errors that are understandable to those skilled in the art and permissible in manufacturing or use.

[0058] refer to Figure 1 This disclosure provides a cleaning device, which can be a steam floor scrubber, steam mop, fabric cleaner, or other intelligent cleaning device that requires steam. In one embodiment of this disclosure, the cleaning device is a handheld cleaning device, such as a handheld washer, handheld vacuum cleaner, handheld floor scrubber, or other handheld cleaning devices well known to those skilled in the art. Similarly, the cleaning device can also be a robotic vacuum cleaner, robotic mop, or a robotic vacuum and mop combo, or other self-propelled cleaning devices.

[0059] The cleaning equipment in this embodiment is a handheld steam floor scrubber. The cleaning equipment includes a main body, a handheld unit, and a floor brush assembly connected to the bottom of the main body. Specifically, the handheld unit is connected to the main body, making it convenient for the user to manually control the cleaning equipment; the floor brush assembly is rotatably connected to the main body, so that when the cleaning equipment is cleaning the work surface, the floor brush assembly can maintain contact with the work surface, thereby achieving the purpose of cleaning the dirt on the work surface.

[0060] like Figure 1 As shown, the floor brush assembly includes: a floor brush housing 1, a roller brush 2, a roller brush cover assembly 3, and a steam unit. The floor brush housing 1 is equipped with a suction port 8, which can be connected to a wastewater tank on the machine body via a suction channel, allowing the cleaning equipment to suck dirt from the suction port 8 into the wastewater tank. The roller brush 2 is rotatably connected to the floor brush housing 1 and is configured to clean the work surface. During use, the roller brush 2 rotates relative to the work surface, thereby achieving cleaning of the work surface.

[0061] refer to Figure 1 , Figure 4 and Figure 5 The roller brush cover assembly 3 includes: a roller brush cover body 31 and a steam output section 32, wherein, as Figure 5As shown, the roller brush cover body 31 and the floor brush housing 1 form a roller brush cavity 310 for engaging with the roller brush 2. This roller brush cavity 310 can have a shape adapted to the roller brush 2, with the roller brush 2 extending from the lower end of the roller brush cavity 310 to contact the working surface. The roller brush cavity 310 provides protection for the roller brush 2 and prevents dirt from being flung out when the roller brush 2 rotates.

[0062] A steam output section 32 is disposed on the roller brush cover body 31 and configured to provide steam to the work surface. The high-temperature steam softens stubborn stains and provides a good sterilization effect, thereby improving the cleaning effect of the roller brush 2 on the work surface. In one embodiment of this disclosure, reference is made to... Figure 1 , Figures 4 to 6 The steam output section 32 includes a steam passage 321 located within the brush cover body 31, and an air jet 322 provided with at least two steam jets 3211 configured to face the working surface. The brush cover body 31 may include a body portion for enclosing and forming the brush cavity 310, and a decorative cover plate exposed on the outside. The steam passage 321 may be an arc-shaped pipe disposed between the body portion and the decorative cover plate.

[0063] Steam passage 321 is used to deliver steam to jet 322, such as Figure 5 As shown, multiple steam nozzles 3211 on the jet nozzle 322 can be arranged along the axis of the roller brush 2. The distance between adjacent steam nozzles 3211 should not be too large, and the spacing between each steam nozzle 3211 can be kept basically consistent, so that the steam ejected by the jet nozzle 322 is continuous and the steam can cover the roller brush 2 and / or the working surface as evenly as possible. In addition, the steam ejected by the two steam nozzles 3211 that are furthest apart can extend beyond the two side edges of the roller brush 2, thereby increasing the steam coverage. Furthermore, when the cleaning equipment cleans along the edges, hard-to-clean corners such as wall edges and cabinet edges can also be covered by steam, thereby improving the cleaning effect of the cleaning equipment.

[0064] refer to Figure 1 and Figure 4 The steam unit includes a steam generating module 4 and a gas-liquid separation module 5. The steam generating module 4 is used to supply steam to the steam output unit 32. Further, the steam generating module 4 is used to heat the liquid to form steam and / or hot water. In one embodiment of this disclosure, refer to... Figure 3 The steam generating module 4 includes a heating chamber 40, which contains a certain amount of liquid and heats the liquid to form steam and / or hot water. The steam flowing out of the steam generating module usually contains a certain amount of liquid water, and during the steam transportation process, as the ambient temperature decreases, some of the steam will condense, thereby increasing the water content in the steam. In order to reduce the water content in the steam, this disclosure provides a gas-liquid separation module 5.

[0065] The gas-liquid separation module 5 is configured to connect the steam generation module 4 and the steam output unit 32. Specifically, the gas-liquid separation module 5 is configured to receive the steam generated by the steam generation module 4, perform gas-liquid separation, and then deliver it to the steam output unit 32. It can be understood that the water content in the steam obtained after gas-liquid separation is significantly reduced. The steam separated by the gas-liquid separation module 5 is configured to be delivered to the steam nozzle 3211 through the steam channel 321, thereby spraying the steam onto the working surface through the steam nozzle 3211, effectively reducing the liquefied condensate content in the steam.

[0066] Furthermore, the gas-liquid separation module 5 has at least two regions with different cross-sectional areas arranged along the steam flow direction, and the cross-sectional area of ​​the region located upstream of the steam flow path is smaller than that of the region located downstream of the steam flow path. Based on Bernoulli's principle, when fluid flows from the region with a smaller cross-sectional area to the region with a larger cross-sectional area, the flow velocity of the gas-liquid mixture will decrease, and the mixture can remain in the region with a larger cross-sectional area for a certain period of time and achieve gas-liquid separation under the action of gravity. This improves the gas-liquid separation effect. The cross-sectional area of ​​the internal chamber of the gas-liquid separation module 5 of this disclosure increases abruptly, thereby improving the gas-liquid separation effect.

[0067] This disclosure significantly reduces the liquid content in the steam emitted from the steam output unit 32 by incorporating a gas-liquid separation module 5, which separates the steam generated by the steam generation module 4 before delivery to the steam output unit 32. During the cleaning process, the steam output unit 32 sprays steam onto the work surface, enhancing both cleaning and sterilization. The low liquid content in the steam effectively prevents liquefaction and dripping, allowing the cleaned work surface to dry quickly without leaving watermarks, thus improving the user experience.

[0068] In one embodiment of this disclosure, reference is made to Figure 1 , Figure 4 and Figure 5 The floor brush assembly also includes a clean water tank 7 disposed on the floor brush housing 1. The clean water tank 7 can store clean water or cleaning fluid, and can supply fluid to at least the roller brush 2 and the steam generating module 4. Figure 5As shown, the gas-liquid separation module 5 and the roller brush cover assembly 3 are configured to be fixedly connected to the clean water tank 7, and the gas-liquid separation module 5 is configured to be detachably connected to the floor brush housing 1 together with the clean water tank 7 and the roller brush cover assembly 3. Specifically, the gas-liquid separation module 5 and the roller brush cover assembly 3 can be fixed to the clean water tank 7 by means of screws, ultrasonic welding, snap-fit ​​fixing or interference fixing, thereby forming an integral structure of the three components. This integral structure can be detachably connected to the floor brush housing 1, and the user can manually disassemble it to manually replenish the clean water tank 7 and manually clean the roller brush cover assembly 3 and the gas-liquid separation module 5.

[0069] In one specific embodiment of this disclosure, the gas-liquid separation module 5 is configured to be located between the clean water tank 7 and the roller brush cover body 31, with the clean water tank 7 located above the gas-liquid separation module 5 and the roller brush cover body 31 located below a portion of the gas-liquid separation module 5. The gas-liquid separation module 5 is at least partially sandwiched between the clean water tank 7 and the roller brush cover body 31. Figure 4 As shown, the top of the roller brush cover body 31 is provided with a first receiving groove 311, such as... Figure 7 As shown, the bottom of the gas-liquid separation module 5 has a first mating part 511 that extends into the first receiving groove 311. The first mating part 511 can be a stepped structure formed by the bottom of the outer shell 51 of the gas-liquid separation module 5. When the gas-liquid separation module 5 and the roller brush cover assembly 3 are respectively fixedly connected to the clean water tank 7, the first mating part 511 is accommodated in the first receiving groove 311, thereby optimizing the component layout of the cleaning equipment and improving the assembly compactness between the roller brush cover body 31 and the gas-liquid separation module 5.

[0070] There can be an assembly gap between the first mating part 511 and the first receiving groove 311, which allows the gas-liquid separation module 5 to have a certain degree of freedom of movement relative to the roller brush cover body 31. When the user installs the integrated structure consisting of the clean water tank 7, the roller brush cover assembly 3, and the gas-liquid separation module 5 onto the floor brush housing 1, in addition to installing the structure in place, it is also necessary to ensure that the gas-liquid separation module 5 can be accurately connected to the steam generating module 4. In this embodiment, the gas-liquid separation module 5 has a certain degree of freedom of movement, which facilitates the matching and installation of the interface of the gas-liquid separation module 5 with the corresponding steam interface, thereby reducing the installation accuracy requirements and allowing the user to complete the docking and installation simply and quickly.

[0071] refer to Figure 5 and Figure 8A second receiving groove 512 is provided on the top of the outer shell 51 of the gas-liquid separation module 5, and an assembly groove adapted to the upper part of the outer shell 51 and a second mating part located in the assembly groove are provided at the bottom of the clean water tank 7. The second mating part is adapted to the second receiving groove 512. When the gas-liquid separation module 5 and the roller brush cover assembly 3 are respectively fixedly connected to the clean water tank 7, the upper part of the outer shell 51 is accommodated in the assembly groove, and the second mating part is accommodated in the second receiving groove 512, thereby optimizing the component layout of the cleaning equipment and improving the assembly compactness between the roller brush cover body 31 and the gas-liquid separation module 5.

[0072] In one embodiment of this disclosure, reference is made to Figure 3 and Figure 4 The steam generating module 4 includes an inlet 43 and an exhaust valve 41 located adjacent to each other. The inlet 43 is used to communicate with the clean water tank 7, and the exhaust valve 41 is used to communicate with the gas-liquid separation module 5. When the user installs the clean water tank 7, the roller brush cover assembly 3, and the gas-liquid separation module 5 as a whole, the clean water tank 7 needs to be connected to the inlet 43, and the gas-liquid separation module 5 needs to be connected to the exhaust valve 41. This disclosure arranges the inlet 43 and the exhaust valve 41 adjacent to each other, improving their compactness and facilitating user connection operations.

[0073] For details, please refer to Figure 5 The bottom of the clean water tank 7 is provided with a liquid injection section 71, which can protrude relative to the bottom surface of the clean water tank 7, so as to connect to the liquid inlet 43 to supply liquid to the steam generating module 4.

[0074] like Figure 3 , Figure 4 As shown, the gas-liquid separation module 5 is provided with a docking part 54, and a top abutment 541 is provided inside the docking part 54. During the installation of the gas-liquid separation module 5, the exhaust valve 41 is configured to extend into the docking part 54 so that the top abutment 541 opens the exhaust valve 41. The docking part 54 can be an inverted funnel-shaped opening formed by the outer shell 51. During installation, the flared slope of the docking part 54 can act as a guide, thereby facilitating the accurate insertion of the upwardly protruding exhaust valve 41 into the docking part 54. A sealing element 42 is provided outside the exhaust valve 41. The sealing element 42 can be a silicone sealing ring fitted onto the exhaust valve 41. After the exhaust valve 41 extends into the docking part 54, the sealing element 42 can cooperate with the flared slope of the docking part 54 to form an airtight structure, thereby preventing steam leakage from the exhaust valve 41.

[0075] like Figure 3As shown, the exhaust valve 41 includes a valve core 411 and an elastic element 412 pre-pressed below the valve core 411. In its natural state, the valve core 411 tends to move upward under the elastic force of the elastic element 412, thereby sealing the steam within the heating chamber 40. After the exhaust valve 41 extends into the docking part 54, the abutment 541, which is located on the inner wall of the top of the housing 51 and extends downward, pushes the valve core 411 downward, thereby opening the exhaust valve 41. During this process, the elastic element 412 is compressed and deformed, and the steam can flow into the gas-liquid separation module 5 under the action of the gas pressure in the heating chamber 40. When the gas-liquid separation module 5 is removed from the floor brush housing 1 along with the clean water tank 7 and the roller brush cover assembly 3, the abutment 541 separates from the valve core 411, and the valve core 411 resets under the elastic force of the elastic element 412, thereby closing the exhaust valve 41 and preventing steam overflow from scalding the user.

[0076] like Figure 4 As shown, the steam generating module 4 is configured to be housed within the brush housing 1, with the liquid inlet 43 and the exhaust valve 41 exposed through the top surface of the brush housing 1. The liquid inlet 43 and the exhaust valve 41 can be arranged along the axial direction of the roller brush 2, as shown in the diagram. Figure 5 As shown, the injection section 71 and the docking section 54, which are respectively used to connect with the liquid inlet 43 and the exhaust valve 41, are also arranged along the axial direction of the roller brush 2. When the integrated structure consisting of the clean water tank 7, the roller brush cover assembly 3, and the gas-liquid separation module 5 is installed onto the floor brush housing 1, the injection section 71 and the liquid inlet 43, and the docking section 54 and the exhaust valve 41 can be connected simultaneously, thereby simplifying the installation steps and improving the user experience.

[0077] In one embodiment of this disclosure, reference is made to Figure 7 The gas-liquid separation module 5 includes a housing 51, which can be formed by a top cover and a bottom cover fastening together. The housing 51 contains a channel cavity 501 and a separation cavity 502 that are interconnected. The channel cavity 501 is connected to the steam generating module 4, and the separation cavity 502 is connected to the steam output section 32. The steam generated by the steam generating module 4 is configured to sequentially pass through the channel cavity 501 and the separation cavity 502 into the steam output section 32. The steam generating module 4 is connected to the channel cavity 501 via a docking part 54. Due to the high gas pressure inside the steam generating module 4, the gas-liquid mixture can naturally flow towards the separation cavity 502 after entering the channel cavity 501 (see reference). Figure 7 View direction, i.e., flowing from right to left.

[0078] The cross-sectional area of ​​the separation chamber 502 perpendicular to the steam flow direction is constructed to be larger than that of the channel chamber 501 perpendicular to the steam flow direction. Based on Bernoulli's principle, when fluid flows from the smaller channel chamber 501 into the larger separation chamber 502, the flow velocity of the gas-liquid mixture will decrease. Within the separation chamber 502, the liquid phase in the low-velocity fluid will be separated to the bottom of the separation chamber 502 under the action of gravity, while the steam will continue to flow in the upper part of the separation chamber 502. The difference in flow velocity between the gas and liquid phases is significant, thereby achieving gas-liquid separation. The cross-sectional area of ​​the internal chamber of the gas-liquid separation module 5 of this disclosure is abruptly increased, thereby improving the gas-liquid separation effect.

[0079] In one embodiment of this disclosure, reference is made to Figure 7 and Figure 10 Let the axial direction of the channel cavity 501 be denoted as the X-axis, the direction perpendicular to the X-axis and located in the same horizontal plane be denoted as the Y-axis, and the thickness direction of the gas-liquid separation module 5 be denoted as the Z-axis. The separation cavity 502 is constructed such that its dimension in the Y-axis direction is larger than that of the channel cavity 501 in the Y-axis direction; and / or, the separation cavity 502 is constructed such that its dimension in the Z-axis direction is larger than that of the channel cavity 501 in the Z-axis direction. It can be understood that the cross-sectional areas of the channel cavity 501 and the separation cavity 502 are the cross-sectional areas on the YZ plane. The dimensions of the separation cavity 502 in both the Y-axis and Z-axis directions are larger than those of the channel cavity 501. This results in the separation cavity 502 having a larger cross-sectional area relative to the channel cavity 501, significantly reducing the flow velocity of the fluid flowing into the separation cavity 502 and improving the gas-liquid separation effect.

[0080] Furthermore, the volume of the separation chamber 502 can be larger than that of the channel chamber 501, allowing the gas-liquid mixture to remain in the separation chamber 502 for a longer period of time to ensure the effectiveness of gas-liquid separation. The gas-liquid mixture entering the separation chamber 502 will not flow into the steam output section 32 before complete separation, but will be fully separated within the separation chamber 502, thereby reducing the liquid content in the steam. The cleaned working surface can dry quickly and is less prone to water stains.

[0081] In one embodiment of this disclosure, reference is made to Figure 6 , Figure 8 and Figure 10 The gas-liquid separation module 5 has an outlet 52 for discharging steam on the wall of the separation chamber 502. The outlet 52 is connected to the steam channel 321, so that the steam obtained from the gas-liquid separation is transported to the jet component 322 through the steam channel 321. The outer casing 51 can be provided with a pipe joint for connecting the steam channel 321 at the position corresponding to the outlet 52. The steam channel 321 can be fitted onto the pipe joint to form a strong and secure gas path connection.

[0082] like Figure 10As shown, the air outlet 52 is offset from the channel cavity 501 in the extending direction (X-axis direction). In this embodiment, the center of the docking part 54 is located on the axis of the channel cavity 501, that is, the air outlet 52 is located off-center from the docking part 54. The air outlet 52 is not directly facing the channel cavity 501, and the gas-liquid mixture from the channel cavity 501 does not rush directly to the air outlet 52. Instead, it needs to stay in the separation cavity 502 for a period of time for sufficient separation before flowing to the air outlet 52, thereby improving the gas-liquid separation effect.

[0083] In one embodiment of this disclosure, such as Figure 8 As shown, the sidewall of the outer casing 51, which has the air outlet 52, is constructed as an arc-shaped surface. When the fluid in the separation chamber 502 reaches the arc-shaped surface, it can turn along the wall, thereby achieving a near-cyclone separation effect within the separation chamber 502 and improving the gas-liquid separation efficiency. Specifically, the separation chamber 502 and the channel chamber 501 share the same sidewall extending straight along the X-axis in the Y-axis direction, as shown in the reference diagram. Figure 10 The arc-shaped sidewall with the air outlet 52 is connected to the sidewall that extends straight along the X-axis, and the air outlet 52 is located away from the straight sidewall in the Y-axis direction, thereby achieving the cyclone separation effect in the separation chamber 502 as described above.

[0084] In one embodiment of this disclosure, reference is made to Figure 2 and Figure 7 A blocking portion 57 is provided in the separation chamber 502 adjacent to the channel chamber 501. The blocking portion 57 is located in the X-axis direction of the channel chamber 501; in the Z-axis and Y-axis directions, the size of the blocking portion 57 is configured to be no smaller than the size of the channel chamber 501. At least a portion of the gas-liquid mixture flowing into the separation chamber 502 from the channel chamber 501 can pass through the blocking portion 57. Since the area of ​​the blocking portion 57 is no smaller than the area of ​​the opening of the channel chamber 501 towards the separation chamber 502, the blocking portion 57 can block the fluid flowing into the separation chamber 502. The blocking portion 57 can reduce the flow rate of the fluid, thereby blocking a portion of the liquid mixed in the vapor. The liquid can condense into droplets on the blocking portion 57 and naturally drip down the blocking portion 57 into the separation chamber 502.

[0085] Preferably, the blocking part 57 can be disposed on the top inner wall of the housing 51. The blocking part 57 can be a baffle extending downwards, with its lower end extending beyond the horizontal plane of the bottom wall of the channel cavity 501. It is understood that the gas-liquid mixture will generally float in the upper part of the chamber, therefore, placing the blocking part 57 on the top wall can improve the blocking effect. Figure 7As shown, the bottom wall of the separation chamber 502 is lower than the bottom wall of the channel chamber 501. When the gas-liquid mixture flowing along the channel chamber 501 enters the separation chamber 502, the gas-liquid mixture concentrated in the upper position will be intercepted by the blocking part 57, thereby separating part of the liquid mixed in the vapor. Although the gas-liquid mixture that diffuses to the lower position will not be intercepted by the blocking part 57, its flow path is lengthened because it bypasses the blocking part 57, thereby increasing the residence time in the separation chamber 502 and helping to achieve full separation.

[0086] In one embodiment of this disclosure, reference is made to Figure 8 and Figure 9 The separation chamber 502 has a drain port 53 at its bottom and an automatic draining device, which includes a sealing element for sealing the drain port 53. The automatic draining device can detect the liquid level in the separation chamber 502 using a float, a level sensor, or similar means. When the liquid level in the separation chamber 502 rises to a first liquid level threshold, the sealing element is disengaged from the drain port 53 to drain the liquid. Specifically, excessive liquid should not accumulate in the separation chamber 502; it needs to be drained promptly to prevent liquid from flowing into the steam output section 32. When the liquid level in the separation chamber 502 drops to a second liquid level threshold, the sealing element is repositioned to seal the drain port 53. Specifically, the drain port 53 needs to be sealed promptly after draining; otherwise, the separation chamber 502 will depressurize, hindering further gas-liquid separation.

[0087] In a specific embodiment of this disclosure, reference is made to Figures 7 to 9 The sealing component is a floating component 55, which can be of various shapes such as a cylinder or a sphere. This disclosure does not impose any restrictions on this. Preferably, such as Figure 8 As shown, the floating element 55 is a sphere. The spherical floating element 55 can sit on the drain port 53 and only needs to float slightly to open the drain port 53. In addition, the spherical floating element 55 has a large mass and its spherical shape can prevent the floating element 55 from being blown up by the steam turbulence, thus preventing it from being blown up before the liquid has accumulated in the separation chamber 502, which would cause the drain port 53 to open and cause pressure relief, thereby improving the sealing effect.

[0088] The cleaning equipment can selectively enter steam mode or non-steam mode. In non-steam mode or non-working condition, the separation chamber 502 is in a static state. When the liquid level in the separation chamber 502 drops to the second liquid level threshold, the gravity of the spherical floating part 55 and the buoyancy provided by the residual water reach a balance, thereby sealing the drain port 53. However, at this time, there will still be condensate remaining in the separation chamber 502. The amount of condensate remaining matches the gravity of the floating part 55.

[0089] When the cleaning equipment is in steam mode, the edge of the drain port 53 is sealed by line contact with the spherical floating element 55. Under the action of steam pressure, because the pressure-bearing area of ​​the spherical floating element 55 is smaller than that of liquid water, the pressure of the spherical floating element 55 is less than that of water under the same conditions. The tension of the condensate at the line contact position is destroyed by the steam pressure. This means that in other non-steam modes, even if there is a gap at the line contact position, the condensate cannot be discharged due to water surface tension. However, in steam mode, the condensate can be discharged through the gap in the line contact position due to the steam pressure. Furthermore, due to the buoyancy of the spherical floating element 55, when the condensate drops below the second liquid level threshold of the separation chamber 502 in the non-steam mode or non-operating condition, the floating element 55 has not yet sealed the drain port 53, allowing the condensate to continue to be discharged from the drain port 53, and the water level continues to drop. As the condensate level decreases, the buoyancy of the floating component 55 decreases. Under the action of steam, when the gravity and buoyancy of the floating component 55 reach dynamic equilibrium, a seal is achieved, thereby ensuring that the amount of residual water in the separation chamber 502 is reduced by using steam pressure when sealing the drain port 53 in the steam working mode.

[0090] The automatic drainage device also includes a floating cavity 56, which is disposed on the floating path of the floating element 55, and at least a portion of the floating element 55 is configured to be confined within the floating cavity 56. The floating cavity 56 restricts the floating element 55 to move vertically only, preventing it from drifting with the fluid to other positions within the separation chamber 502. Furthermore, even in the case of inversion (such as during factory shipping of cleaning equipment), the floating element 55 remains confined within the floating cavity 56, thereby preventing the floating element 55 from deviating from the drain port 53 and causing pressure leakage.

[0091] In one embodiment of this disclosure, reference is made to Figure 7 and Figure 11 The top wall of the separation chamber 502 is provided with a downwardly extending limiting part 58, which is configured to be located above the floating member 55, that is, on the floating path of the floating member 55. The floating member 55 has a maximum floating height under the limiting action of the limiting part 58. The limiting part 58 can be a column provided on the inner wall of the upper cover. When the floating member 55 floats to the top of the limiting part 58, the floating member 55 cannot continue to float upwards, thereby achieving a height limit. Specifically, the floating height of the floating member 55 is 2-4.5 mm, and the floating member 55 will not float to an excessively high position under the action of the limiting part 58.

[0092] The limiting part 58 and the floating cavity 56 together restrict the range of motion of the floating part 55, thereby ensuring that the floating part 55 can float up and drain the liquid in time when the liquid level in the separation cavity 502 reaches the first liquid level threshold, and remain in the position of blocking the drain port 53 when the liquid level in the separation cavity 502 drops to the second liquid level threshold. During the cleaning operation of the cleaning equipment, the floating part 55 may be shaken, but the floating part 55 will not move to the position of disengaging from the drain port 53 during this process, thus avoiding pressure leakage.

[0093] This disclosure does not limit the specific arrangement of the floating cavity 56. As mentioned above, the outer casing 51 can be formed by the snap-fitting of an upper cover and a lower cover, see reference. Figures 7 to 9 The floating cavity 56 can be disposed on the upper cover and extends downward from the inner wall of the upper cover. In this embodiment, the limiting part 58 can be located within the floating cavity 56. Figure 7 As shown, the diameter of the floating cavity 56 is slightly larger than the diameter of the floating member 55, so that the floating member 55 will not get stuck in the floating cavity 56 and can move up and down within the floating cavity 56. The floating cavity 56 extends downward beyond the limiting portion 58, and the sidewall of the floating cavity 56 at least partially covers the floating member 55, thereby limiting the floating member 55 in the circumferential direction by the floating cavity 56 and in the vertical direction by the limiting portion 58 located within the floating cavity 56.

[0094] refer to Figures 11 to 13 The floating cavity 56 can also be located in the lower cover and extend upward from the inner wall of the lower cover. In this embodiment, the drain port 53 can be located at the center of the floating cavity 56. Figure 11 As shown, the diameter of the floating cavity 56 is slightly larger than the diameter of the floating member 55, so that the floating member 55 will not get stuck in the floating cavity 56 and can move up and down within the floating cavity 56. The limiting part 58 can extend downward to enter the floating cavity 56, or be flush with the upper opening of the floating cavity 56, or slightly higher than the upper opening of the floating cavity 56, thereby preventing the floating member 55 from falling out of the floating cavity 56.

[0095] Understandably, in separation chamber 502, the separated vapor will float at the upper position, while the liquid will drip to the lower position. Based on this, as shown in section 7... Figure 9 As shown, when the floating cavity 56 is installed on the top cover, the side wall of the floating cavity 56 is configured to have a gap with the inner wall of the separation cavity 502, so that the floating cavity 56 will not form a dead airflow angle with the side wall of the separation cavity 502, and the steam can bypass the floating cavity 56 through the gap, thereby avoiding the formation of trapped air in the separation cavity 502, and at the same time avoiding the obstruction of cyclone separation in the separation cavity 502.

[0096] like Figures 11 to 13As shown, when the floating cavity 56 is located in the lower cover, at least one side of the floating cavity 56 has an opening 562, allowing liquid dripping onto the bottom wall of the separation cavity 502 to flow through the opening 562 to the drain port 53 located within the floating cavity 56. Without the opening 562, a large amount of liquid would be unable to enter the floating cavity 56, thus preventing drainage through the drain port 53, resulting in excessive liquid accumulation within the separation cavity 502.

[0097] In a specific embodiment of this disclosure, reference is made to Figure 9 and Figure 12 The inner wall of the floating cavity 56 is provided with baffles 561. Multiple baffles 561 can be provided, and they are spaced apart along the circumferential direction of the floating cavity 56 on the inner wall. The baffles 561 can extend vertically or be constructed in a wave-like, curved, or other shape. When airflow or a gas-liquid mixture passes through the floating component 55, the floating component 55 may be blown up before the liquid level in the separation chamber 502 reaches the first liquid level threshold, leading to pressure relief. This embodiment reduces the impact of the fluid on the floating component 55 by providing multiple baffles 561 on the inner wall of the floating cavity 56.

[0098] In one embodiment of this disclosure, the floor brush housing 1 is further provided with a flow guide, which is interference-fitted with the roller brush 2, such as... Figure 2 As shown, the drainage component can be a water spray plate 6 located on the rear side of the roller brush 2 on the brush housing 1. The water spray plate 6 can be connected to the clean water tank 7, thereby wetting the roller brush 2. The water spray plate 6 is interference-fitted with the roller brush 2, and in addition to facilitating wetting, the water spray plate 6 also functions as a scraper. As the roller brush 2 rotates, the water spray plate 6 can scrape the roller brush 2 and remove the dirt carried by the roller brush 2, such as... Figure 1 As shown, the suction port 8 is located below the spray plate 6, so the dirt scraped off can be directly sucked up by the suction port 8 without falling to the ground. In other embodiments, the guide includes a squeegee that contacts the roller brush 2, and the spray plate 6 does not directly contact the roller brush 2, but rather the roller brush 2 directly contacts the spray plate 6 through a squeegee located below the spray plate 6. Liquid dripping onto the spray plate 6 can be guided by the spray plate 6 to the squeegee that contacts the roller brush 2.

[0099] Continue to refer to Figure 2The roller brush cover body 31 is provided with a drainage channel 312, which is configured to connect the drainage port 53 and the drainage component. It should be noted that "connection" here is not limited to structures that are directly connected. As long as there is a liquid passage between the drainage port 53, the drainage channel 312, and the drainage component, it can be understood that the drainage channel 312 connects the drainage port 53 and the drainage component. For example, there can be a gap between the drainage channel 312 and the drainage port 53, and the drainage channel 312 can be located below the drainage port 53, allowing liquid flowing from the drainage port 53 to flow into the drainage channel 312 under gravity. Of course, the drainage port 53, the drainage channel 312, and the drainage component can also be connected sequentially via pipe connections. The liquid separated by the gas-liquid separation module 5 is configured to flow sequentially through the drainage port 53, the drainage channel 312, and the drainage component to the roller brush 2. The liquid from the drain port 53 is the liquid separated by the gas-liquid separation module 5. The liquid can be guided to the spray plate 6 and then flow to the roller brush 2, thus preventing it from dripping onto the ground and leaving water stains. In other embodiments, the spray plate 6 does not directly contact the roller brush 2, but rather the roller brush 2 is in direct contact through a scraper blade located below the spray plate 6. The spray plate 6 and the scraper blade are located below the outlet of the drain channel 312. Under the action of gravity, the liquid discharged from the separation chamber 502 flows through the drain channel 312 to the spray plate 6, and is then guided by the spray plate 6 to the scraper blade that contacts the roller brush 2, and then by the scraper blade to the roller brush 2.

[0100] During the operation of the cleaning equipment, steam will be ejected from the jet nozzle 322 located in front of the roller brush 2, and some of the steam will flow along the gap between the roller brush 2 and the roller brush cover body 31 (see reference). Figure 1 In the view direction, the steam flows clockwise and is sucked away by the suction port 8, resulting in a reduction in the amount of steam sprayed onto the ground, causing some waste. To solve the above problem, in one embodiment of this disclosure, reference is made to... Figure 2 and Figure 5 A steam baffle 33 is provided inside the roller brush cover body 31. The steam baffle 33 is constructed to extend from the roller brush cover body 31 and fit against the roller brush 2 in an interference fit. The steam baffle 33 can be made of a flexible material such as silicone or rubber, so that the steam baffle 33 fits tightly against the roller brush 2 without rigidly hindering the rotation of the roller brush 2. When the steam flows to the steam baffle 33, it will be blocked and will not continue to flow clockwise, thus preventing it from being sucked away by the suction port 8, thereby increasing the amount of steam sprayed onto the ground and avoiding steam waste. Figure 2 As shown, the outlet of the drain channel 312 is located on the rear side of the steam baffle 33, so that the drain path does not pass through the steam area, further avoiding steam waste.

[0101] Application scenarios

[0102] In home cleaning scenarios, the cleaning equipment is a steam floor scrubber. The steam floor scrubber includes a floor brush assembly, which comprises: a floor brush housing 1, a roller brush 2, a roller brush cover assembly 3, a steam generating module 4, and a gas-liquid separation module 5. The outer shell 51 of the gas-liquid separation module 5 has an interconnected channel cavity 501 and a separation cavity 502.

[0103] During the operation of the steam floor scrubber, steam generated by the steam generating module 4 enters the gas-liquid separation module 5 through the exhaust valve 41 and the docking part 54. The steam generating module 4 is connected to the channel cavity 501 through the docking part 54. Due to the high air pressure inside the steam generating module 4, the gas-liquid mixture can naturally flow towards the separation cavity 502 after entering the channel cavity 501. The cross-sectional area of ​​the separation cavity 502 perpendicular to the steam flow direction is constructed to be larger than that of the channel cavity 501 perpendicular to the steam flow direction. When fluid flows from the smaller cross-sectional area of ​​the channel cavity 501 into the larger cross-sectional area of ​​the separation cavity 502, the flow rate of the gas-liquid mixture will decrease, and the gas-liquid mixture will remain in the separation cavity 502 for a certain period of time, thereby improving the gas-liquid separation effect.

[0104] The gas-liquid separation module 5 has an outlet 52 for discharging steam on the wall of the separation chamber 502. The outlet 52 is used to communicate with the steam channel 321, so that the steam obtained from the gas-liquid separation is transported to the jet nozzle 322 through the steam channel 321. The jet nozzle 322 is provided with multiple steam nozzles 3211, which face the working surface.

[0105] This disclosure significantly reduces the liquid content in the steam emitted from the steam output unit 32 by incorporating a gas-liquid separation module 5, which separates the steam generated by the steam generation module 4 before delivery to the steam output unit 32. During the cleaning process, the steam output unit 32 sprays steam onto the work surface, enhancing both cleaning and sterilization. The low liquid content in the steam effectively prevents liquefaction and dripping, allowing the cleaned work surface to dry quickly without leaving watermarks, thus improving the user experience.

[0106] The bottom of the separation chamber 502 is provided with a drain port 53. The separation chamber 502 is provided with a ball floating member 55 for sealing the drain port 53, and a floating cavity 56 is provided on the floating path of the floating member 55. At least part of the floating member 55 is confined in the floating cavity 56. The floating cavity 56 restricts the floating member 55 to move up and down in the vertical direction only, and it will not drift with the fluid to other positions in the separation chamber 502.

[0107] When the liquid level in the separation chamber 502 rises to the first liquid level threshold, the floating element 55 disengages from the drain port 53, thereby draining the liquid in a timely manner and preventing excessive liquid accumulation in the separation chamber 502. When the liquid level in the separation chamber 502 drops to the second liquid level threshold, the floating element 55 seals the drain port 53 to prevent pressure loss in the separation chamber 502. This disclosure achieves automatic drainage and water sealing by incorporating the floating element 55.

[0108] The various embodiments of this disclosure have been described above. These descriptions are exemplary and not exhaustive, and are not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
