Abstract
Description
Technical Field
[0001] This application relates to the field of cleaning equipment technology, and more particularly to a sewage tank and cleaning equipment. Background Technology
[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors while simultaneously drying wastewater and removing it from the site. It has advantages such as being environmentally friendly, energy-saving, and highly efficient.
[0003] In related technologies, floor scrubbers have a wastewater tank and a negative pressure component. When the floor scrubber moves back and forth on the surface to be cleaned, the negative pressure component generates negative pressure inside the floor scrubber by drawing in air, so as to suck dust, hair and wastewater and other dirt from the surface to be cleaned into the wastewater tank.
[0004] However, when the floor scrubber moves back and forth on the surface to be cleaned, due to inertia, the wastewater will hit the inner wall of the wastewater tank, causing surging and splashing, and then be sucked into the negative pressure component, resulting in damage to the negative pressure component. Utility Model Content
[0005] Based on this, this application provides a sewage tank and a cleaning device to solve the problem of sewage surging and splashing when it hits the inner wall of the sewage tank, and then being sucked into the negative pressure component.
[0006] Firstly, the wastewater tank provided in this application includes:
[0007] The housing contains a sewage inlet channel;
[0008] The separation component is located inside the box and divides the box into an exhaust chamber, a solid chamber, and a liquid chamber. The liquid chamber and the exhaust chamber are connected to the solid chamber, and the solid chamber is connected to the sewage inlet channel. The separation component has an exhaust port that is connected to the exhaust chamber and is used to connect to a negative pressure source.
[0009] The liquid chamber, solid chamber, and exhaust port are arranged sequentially along the extension direction of the housing; when the housing is in a flat position, the solid chamber is located below the exhaust chamber.
[0010] Thus, during operation, the vent chamber and vent are always positioned above the sewage, creating a height difference between them. Furthermore, the separation components can suppress surges, making it difficult for sewage to rise into the vent and be drawn into the negative pressure source.
[0011] In one possible implementation, the sewage tank provided in this application also includes a cover, with an installation opening formed at the end of the tank facing the vent, and the cover covering the installation opening, with the cover communicating with the vent.
[0012] Thus, the cover is placed over the mounting opening of the box to form a sealed inner cavity.
[0013] In one possible implementation, the wastewater tank provided in this application further includes a first filter element disposed on the cover, the first filter element being used to filter the gas discharged through the exhaust port.
[0014] In this way, the first filter element can filter the gas discharged through the exhaust port to prevent small debris, dust and other small objects from entering the negative pressure source with the gas and causing damage to the negative pressure source.
[0015] In one possible implementation, the wastewater tank provided in this application further includes a detection element disposed on the separation assembly, with at least a portion of the detection element located within the liquid chamber, and the detection element is used to detect the liquid level of the wastewater within the liquid chamber.
[0016] In this way, the detection device extends into the liquid chamber, and when the liquid level of the sewage in the liquid chamber is too high, the detection device can issue a warning signal to remind the user to clean the dirt in the sewage tank.
[0017] In one possible implementation, the wastewater tank provided in this application further includes a seal, which is disposed on the separation assembly and abuts against the inner wall of the tank.
[0018] In this way, the gap between the separation component and the housing is filled by a sealant to ensure the sealing performance between the separation component and the housing.
[0019] In one possible implementation, the sewage tank provided in this application includes a separation component comprising a first separation member and a second separation member disposed on the first separation member, wherein the first separation member extends along the extension direction of the tank body and the second separation member extends along a direction intersecting the extension direction of the tank body;
[0020] Both the first and second separators abut against the inner wall of the housing, dividing the housing into an exhaust chamber, a solid chamber, and a liquid chamber. The first separator is located between the exhaust chamber and the solid chamber, and the second separator is located on the same side of the exhaust chamber and the solid chamber.
[0021] Thus, the venting chamber and the solid chamber are separated from the liquid chamber by the second separator. When the sewage tank is not in a flat position (e.g., upright or tilted), the sewage in the liquid chamber is located below the venting chamber and the solid chamber, and the second separator can suppress the surge in the liquid chamber. The venting chamber and the solid chamber are separated by the first separator. When the sewage tank is in a flat position, the first separator can suppress the surge in the solid chamber.
[0022] In one possible implementation, the sewage tank provided in this application has a sewage inlet connector on the first separator, the sewage inlet connector is located in the exhaust chamber, and the sewage inlet connector connects the sewage inlet channel and the solid chamber.
[0023] When the tank is in a flat position, both the liquid chamber and the solid chamber are located below the sewage inlet channel.
[0024] In this way, after the sewage inlet channel sucks in the dirt, the dirt can be guided into the solid chamber through the sewage inlet connector. Furthermore, when the tank is in a flat position, both the liquid chamber and the solid chamber are located below the sewage inlet channel, thus creating a height difference between the liquid chamber and the solid chamber and the sewage inlet channel to prevent sewage in the solid chamber from flowing back into the sewage inlet channel.
[0025] In one possible implementation, the sewage tank provided in this application has an extension on the first separating member. The extension is located inside the solid cavity, and the extension and part of the first separating member form a guide channel, which is connected to the sewage inlet connector.
[0026] In this way, the guide channel formed by the extension and the first separating member can guide the dirt to the inner wall of the box, so that the dirt enters the solid cavity along the inner wall of the box, thereby reducing the phenomenon of dirt collision and splashing.
[0027] In one possible implementation, the sewage tank provided in this application includes an extension portion comprising a first extension section disposed on a first separator and at least two second extension sections, wherein the second extension sections are disposed on opposite sides of the first extension section.
[0028] The first extension section, the second extension section, and part of the first separation component together form the guide channel.
[0029] Thus, the guide channel can be formed by the first extension section, the second extension section, and part of the first separation component.
[0030] In one possible implementation, the sewage tank provided in this application has a second separator, a first extension section, and a second extension section arranged sequentially along the extension direction of the first separator.
[0031] When the box is in a flat position, both the first extension section and the second extension section extend downwards in the vertical direction, and the extension length of the first extension section is less than the extension length of the second extension section.
[0032] Thus, both the first and second extension sections extend along the second direction, so that the formed guide channel guides the dirt to the inner wall of the housing. Furthermore, the extension length of the first extension section is less than the extension length of the second extension section, and a dirt inlet channel is formed between the first extension section and the inner wall of the housing, so that the dirt in the guide channel enters the solid cavity through the dirt inlet channel.
[0033] In one possible implementation, the sewage tank provided in this application has a first extension section with an extension length greater than 0 mm and less than or equal to 200 mm.
[0034] And / or, the extension length of the second extension segment is greater than 0 mm and less than or equal to 200 mm.
[0035] This ensures that the first extension segment and the second extension segment form a guiding channel.
[0036] In one possible implementation, the wastewater tank provided in this application has a wastewater channel on the second separator, which connects the solid cavity and the liquid cavity.
[0037] Thus, after the dirt enters the solid chamber, the solid matter in the dirt is retained in the solid chamber by the second separator, while the sewage in the dirt enters the liquid chamber through the sewage channel.
[0038] In one possible implementation, the wastewater tank provided in this application further includes a second filter element on the second separator, the second filter element being located inside the solid cavity and covering the wastewater channel.
[0039] In this way, the second filter element can filter out dirt entering the sewage channel, thereby blocking smaller solids in the solid cavity.
[0040] In one possible implementation, the sewage tank provided in this application has a sewage channel extending along the extension direction of the second separator. The second separator has an inlet and a outlet communicating with the sewage channel. The inlet is communicating with the solid cavity, and the outlet is communicating with the liquid cavity.
[0041] When the container is in a flat position, the drain outlet is located above the inlet.
[0042] In this way, dirt can enter the sewage channel through the inlet on the second separator and enter the liquid chamber through the outlet on the second separator. When the tank is in a flat position, the outlet is located above the inlet, so that there is a certain height difference between the outlet and the sewage in the liquid chamber, making it difficult for sewage in the liquid chamber to backflow into the outlet.
[0043] In one possible implementation, the sewage tank provided in this application has a baffle portion on the first separator, the baffle portion being located inside the exhaust chamber, and the baffle portion and part of the first separator forming an exhaust port.
[0044] Thus, the vent is formed by the enclosure and the first separator. The enclosure is located inside the vent chamber. When the sewage tank is not in a flat position, the second separator separates the enclosure from the sewage in the liquid chamber. When the sewage tank is in a flat position, the first separator separates the enclosure from the sewage that flows back into the solid chamber, thereby preventing sewage from directly entering the vent.
[0045] In one possible implementation, the sewage tank provided in this application has at least one vent hole on the first separator, the vent hole connecting the exhaust chamber and the solid chamber.
[0046] Thus, after the gas enters the solid cavity, it can enter the exhaust cavity through the vent on the first separator, and then enter the exhaust port from the exhaust cavity.
[0047] In one possible implementation, the sewage tank provided in this application has vents and enclosures spaced apart in the extending direction of the first separator.
[0048] In this way, by setting the vent hole and the exhaust port formed by the enclosure to be staggered, the vent hole and the exhaust port are kept away from each other, so as to prevent sewage from splashing into the exhaust chamber and then directly entering the exhaust port.
[0049] In one possible implementation, the wastewater tank provided in this application has a venting channel formed by the first separator, the second separator, and the inner wall of the tank body, and the venting channel connects the liquid chamber and the vent.
[0050] Thus, a small portion of the gas entering the liquid chamber can, under the influence of the negative pressure source, enter the exhaust port in the exhaust chamber through the exhaust channel.
[0051] In one possible implementation, the sewage tank provided in this application has a minimum cross-sectional area of S1 for the exhaust channel and a minimum cross-sectional area of S2 for the exhaust port, where 1%≤S1 / (S1+S2)≤60%.
[0052] This ensures that the gas in the exhaust channel can enter the exhaust port under the action of the negative pressure source. Furthermore, as the cross-sectional area of the exhaust channel gradually increases, the flow velocity of the gas through the exhaust channel also decreases accordingly, which can prevent or reduce the drawing of sewage into the exhaust port through the exhaust channel.
[0053] In one possible implementation, the wastewater tank provided in this application has at least one first baffle on the second separator. The first baffle is located inside the liquid chamber and is used to prevent wastewater from entering the exhaust channel.
[0054] Thus, the first baffle is set in accordance with the exhaust channel to prevent sewage from the liquid chamber from entering the exhaust channel.
[0055] In one possible implementation, the wastewater tank provided in this application has at least one second baffle in the exhaust channel, the second baffle being used to prevent wastewater from the liquid chamber from entering the exhaust port.
[0056] Thus, by setting a second baffle in the exhaust channel, the sewage entering the exhaust channel is further blocked, preventing the sewage in the exhaust channel from being sucked into the exhaust port.
[0057] In one possible implementation, the wastewater tank provided in this application has an exhaust channel that extends along the extension direction of the tank body.
[0058] This extends the path of the exhaust channel, allowing wastewater to remain within it and preventing wastewater entering the exhaust channel from being sucked into the exhaust port.
[0059] Secondly, the cleaning equipment provided in this application includes a main unit and a wastewater tank as described above, wherein the wastewater tank is detachably connected to the main unit.
[0060] In addition to the technical problems solved by the embodiments of this application, the technical features constituting the technical solutions, and the beneficial effects brought about by the technical features of these technical solutions described above, other technical problems that the cleaning equipment provided by this application can solve, other technical features included in the technical solutions, and the beneficial effects brought about by these technical features will be further described in detail in the specific embodiments.

[0085] Furthermore, the terms “comprising” and “having”, and any variations thereof, are intended to cover non-exclusive inclusion, such that a process, method, system, product, or display that includes a series of steps or units is not necessarily limited to those steps or units that are explicitly listed, but may include other steps or units that are not explicitly listed or that are inherent to such process, method, product, or display.
[0086] In related technologies, floor scrubbers have a wastewater tank and a negative pressure component. When the floor scrubber moves back and forth on the surface to be cleaned, the negative pressure component generates negative pressure inside the floor scrubber by drawing air in, so as to suck dust, hair and wastewater and other dirt from the surface to be cleaned into the wastewater tank.
[0087] However, when the floor scrubber moves back and forth on the surface to be cleaned, due to inertia, the wastewater will hit the inner wall of the wastewater tank, causing surging and splashing, and then be sucked into the negative pressure component, resulting in damage to the negative pressure component.
[0088] For example, when the wastewater tank is in a flat or non-flat state, the wastewater in the tank is easily drawn into the negative pressure source during the cleaning process of the floor scrubber pushing and pulling back and forth.
[0089] In view of the above problems, this application provides a wastewater tank and a cleaning device. The wastewater tank includes a tank body and a separation component. A wastewater inlet channel is provided inside the tank body, and the separation component is disposed inside the tank body, dividing the tank body into an exhaust chamber, a solid chamber, and a liquid chamber. The liquid chamber and the exhaust chamber are both connected to the solid chamber, and the solid chamber is connected to the wastewater inlet channel. The separation component has an exhaust port connected to the exhaust chamber, which is used to connect to a negative pressure source. The liquid chamber, solid chamber, and exhaust port are arranged sequentially along the extension direction of the tank body; when the tank body is in a horizontal position, the solid chamber is located below the exhaust chamber. During the operation of the floor scrubber, the exhaust chamber and exhaust port inside the wastewater tank are always located above the wastewater, creating a height difference between the exhaust chamber / port and the wastewater. Furthermore, the separation component can suppress surges, making it difficult for wastewater to rise into the exhaust port and be drawn into the negative pressure source.
[0090] The following describes in detail the specific implementation of the sewage tank and cleaning equipment provided in the embodiments of this application, with reference to the accompanying drawings.
[0091] Reference Figures 1 to 10 As shown in the embodiment of this application, the sewage tank 10 includes a tank body 100 and a separation component 200. A sewage inlet channel 110 is provided inside the tank body 100. The separation component 200 is disposed inside the tank body 100, dividing the tank body 100 into an exhaust chamber 101, a solid chamber 102, and a liquid chamber 103. Both the liquid chamber 103 and the exhaust chamber 101 are connected to the solid chamber 102. The solid chamber 102 is connected to the sewage inlet channel 110. The separation component 200 has an exhaust port 201 connected to the exhaust chamber 101, which is used to connect to a negative pressure source.
[0092] The liquid chamber 103, the solid chamber 102, and the exhaust port 201 are arranged sequentially along the extension direction of the housing 100; when the housing 100 is in a flat position, the solid chamber 102 is located below the exhaust chamber 101.
[0093] It is understood that the wastewater tank 10 provided in this application can be used in cleaning equipment, such as a floor scrubber. The floor scrubber may include a negative pressure source (e.g., a suction motor), which is connected to the exhaust port 201 on the separation component 200 of the wastewater tank 10. The negative pressure source creates a negative pressure inside the floor scrubber by suctioning gas, thereby removing dust, hair, and wastewater from the surface to be cleaned. The wastewater tank 10 is used to recycle the dirt, and the gas enters the negative pressure source through the exhaust port 201.
[0094] Reference Figure 3 , Figure 6 and Figure 8As shown, solid arrows indicate the direction of dirt flow, and dashed arrows indicate the direction of gas flow. The separation component 200 divides the housing 100 into an exhaust chamber 101, a solid chamber 102, and a liquid chamber 103. The solid chamber 102 is connected to the sewage inlet channel 110. Thus, after dirt is sucked into the sewage tank 10 by the sewage inlet channel 110, it first enters the solid chamber 102, where the solid matter in the dirt remains. The sewage in the dirt then enters the liquid chamber 103. The sucked-in gas enters the exhaust chamber 101 from the solid chamber 102 and then enters the negative pressure source from the exhaust port 201.
[0095] The liquid chamber 103, solid chamber 102, and exhaust port 201 are arranged sequentially along the extension direction of the housing 100, with the exhaust chamber 101 located between the wastewater inlet channel 110 and the solid chamber 102. Thus, when the housing 100 is not in a horizontal position (e.g., upright or tilted), the liquid chamber 103 is always located below the solid chamber 102, exhaust chamber 101, and exhaust port 201. During the back-and-forth pushing and pulling cleaning process of the floor scrubber, the separation component 200 can suppress the surge generated within the liquid chamber 103 to prevent wastewater from splashing directly into the exhaust chamber 101, being sucked into the exhaust port 201, and entering the negative pressure source, potentially damaging the negative pressure source.
[0096] When the housing 100 is in a flat position, the sewage in the liquid chamber 103 will flow back into the solid chamber 102. Since the solid chamber 102 is located below the exhaust chamber 101, the separation component 200 can suppress the surge generated in the solid chamber 102 during the back-and-forth pushing and pulling cleaning process of the floor scrubber, so as to prevent the sewage in the solid chamber 102 from splashing directly into the exhaust port 201 and causing damage to the negative pressure source.
[0097] In this way, during the operation of the floor scrubber, the exhaust chamber 101 and exhaust port 201 in the wastewater tank 10 are always located above the wastewater. There is a drop between the exhaust chamber 101 and exhaust port 201 and the wastewater, and the separation component 200 can suppress the surge, so that the wastewater is not easy to rise into the exhaust port 201, causing the wastewater to be sucked into the negative pressure source.
[0098] Reference Figure 4 and Figure 5 As shown, in some embodiments, the sewage tank 10 provided in this application embodiment further includes a cover 300. The end of the tank 100 facing the exhaust port 201 forms an installation opening, and the cover 300 is placed on the installation opening. The cover 300 is connected to the exhaust port 201.
[0099] In this way, the cover 300 is placed over the mounting opening of the box 100 to form a sealed inner cavity.
[0100] The cover 300 is connected to the separation component 200, and the cover 300 can also serve to install and support the separation component 200, ensuring the stability of the installation of the separation component 200.
[0101] Reference Figure 4 and Figure 5 As shown, in some embodiments, the sewage tank 10 provided in this application embodiment further includes a first filter element 400, which is disposed on the cover 300 and is used to filter the gas discharged through the exhaust port 201.
[0102] In this way, the first filter element 400 can filter the gas discharged through the exhaust port 201 to prevent small debris, dust and other small objects from entering the negative pressure source with the gas and causing damage to the negative pressure source.
[0103] For example, the first filter element 400 can be HEPA, filter cotton, filter screen, etc., and the embodiments of this application do not impose too many restrictions on it.
[0104] Reference Figures 2 to 5 As shown, in some embodiments, the wastewater tank 10 provided in this application embodiment further includes a detection element 500, which is disposed on the separation component 200. At least a portion of the detection element 500 is located in the liquid chamber 103, and the detection element 500 is used to detect the liquid level of the wastewater in the liquid chamber 103.
[0105] In this way, the detection element 500 extends into the liquid chamber 103. When the liquid level of the sewage in the liquid chamber 103 is too high, the detection element 500 can issue a warning signal to remind the user to clean the dirt in the sewage tank 10.
[0106] For example, the detection element 500 can be a liquid level monitor commonly used in the prior art, and this application embodiment does not impose too many restrictions on it.
[0107] Reference Figure 5 As shown, in some embodiments, the sewage tank 10 provided in this application embodiment further includes a sealing element 600, which is disposed on the separation component 200 and abuts against the inner wall of the tank body 100.
[0108] In this way, the gap between the separation assembly 200 and the housing 100 is filled by the seal 600 to ensure the sealing performance between the separation assembly 200 and the housing 100.
[0109] Furthermore, a seal 600 can also be provided between the cover 300 and the box 100 to prevent dirt from leaking out of the box 100.
[0110] For example, the seal 600 can be made of elastic materials such as silicone gaskets or rubber gaskets, and this application embodiment does not impose too many restrictions on this.
[0111] Reference Figures 5 to 9 As shown, in some embodiments, the separation component 200 includes a first separation member 210 and a second separation member 220 disposed on the first separation member 210. The first separation member 210 extends along the extension direction of the housing 100, and the second separation member 220 extends along a direction intersecting the extension direction of the housing 100.
[0112] Both the first separating member 210 and the second separating member 220 abut against the inner wall of the housing 100, dividing the housing 100 into an exhaust chamber 101, a solid chamber 102 and a liquid chamber 103. The first separating member 210 is located between the exhaust chamber 101 and the solid chamber 102, and the second separating member 220 is located on the same side of the exhaust chamber 101 and the solid chamber 102.
[0113] Thus, the exhaust chamber 101 and solid chamber 102 are separated from the liquid chamber 103 by the second separator 220. When the sewage tank 10 is not in a flat state (e.g., upright or tilted), the sewage in the liquid chamber 103 is located below the exhaust chamber 101 and solid chamber 102, and the second separator 220 can suppress the surge in the liquid chamber 103. The exhaust chamber 101 and solid chamber 102 are separated by the first separator 210. When the sewage tank 10 is in a flat state, the first separator 210 can suppress the surge in the solid chamber 102.
[0114] The first separator 210 may be provided with a gas passage hole, or the first separator 210 and the inner wall of the housing 100 may jointly form a gas passage hole, so that the gas in the solid cavity 102 can enter the exhaust cavity 101 through the gas passage hole.
[0115] To facilitate understanding of directions, an XY plane coordinate system is established in the accompanying drawings of the instruction manual. The direction of the X-axis is the first direction, and the direction of the Y-axis is the second direction. Specifically, the extension directions of the tank 100 and the first separating member 210 are both the first direction, and the extension direction of the second separating member 220 is the second direction. When the sewage tank 10 is in a horizontal position, the first direction is horizontal, and the second direction is vertical.
[0116] Preferably, the first direction is perpendicular to the second direction.
[0117] The first separating member 210 and the second separating member 220 can be integrally formed.
[0118] Reference Figure 3 , Figure 5 and Figure 6As shown, in some embodiments, the first separator 210 is provided with a sludge inlet connector 211, which is located inside the exhaust chamber 101 and connects the sludge inlet channel 110 with the solid chamber 102. When the housing 100 is in a flat state, both the liquid chamber 103 and the solid chamber 102 are located below the sludge inlet channel 110.
[0119] In this way, after the sewage inlet channel 110 sucks in the dirt, the dirt can be guided into the solid chamber 102 through the sewage inlet connector 211. Furthermore, when the tank 100 is in a flat position, both the liquid chamber 103 and the solid chamber 102 are located below the sewage inlet channel 110, so that a height difference is formed between the liquid chamber 103 and the solid chamber 102 and the sewage inlet channel 110, thereby preventing sewage in the solid chamber 102 from flowing back into the sewage inlet channel 110.
[0120] The inlet connector 211 is located inside the exhaust chamber 101, so that when the housing 100 is in a flat position, the liquid chamber 103 and the solid chamber 102 are also located below the inlet connector 211.
[0121] Reference Figure 3 , Figure 6 and Figure 9 As shown, in some embodiments, the first separating member 210 is further provided with an extension 212, which is located in the solid cavity 102. The extension 212 and part of the first separating member 210 form a guide channel 2121, which is connected to the sewage inlet connector 211.
[0122] In this way, the guide channel 2121 formed by the extension 212 and the first separating member 210 can guide the dirt to the inner wall of the box 100, so that the dirt enters the solid cavity 102 along the inner wall of the box 100, thereby reducing the phenomenon of dirt collision and splashing.
[0123] Among them, reference Figure 3 , Figure 6 and Figure 9 As shown, the extension 212 can extend in a second direction. When the wastewater tank 10 is not in a horizontal position, the extension 212 can guide dirt to flow downward along the inner wall of the tank 100. When the wastewater tank 10 is in a horizontal position, the extension 212 can guide dirt to flow downward vertically onto the inner wall of the tank 100 to reduce dirt splashing.
[0124] Reference Figures 5 to 9As shown, in some embodiments, the extension 212 includes a first extension segment 2122 disposed on the first separator 210 and at least two second extension segments 2123, with the second extension segments 2123 disposed on opposite sides of the first extension segment 2122. The first extension segment 2122, the second extension segments 2123 and part of the first separator 210 together form a guide channel 2121.
[0125] Thus, the guide channel 2121 can be formed by the first extension section 2122, the second extension section 2123, and part of the first separation member 210.
[0126] Among them, reference Figure 9 As shown, the first extension section 2122 and the second extension section 2123 can both be straight plate structures, and the cross-sectional area of the guide channel 2121 gradually increases from the inlet connector 211 toward the side away from the first separator 210 (i.e. along the second direction), so as to ensure the maximum amount of dirt passing through the guide channel 2121 and avoid dirt clogging in the inlet connector 211.
[0127] Reference Figure 9 As shown, in some embodiments, the second separator 220, the first extension 2122, and the second extension 2123 are arranged sequentially along the extension direction of the first separator 210. When the housing 100 is in a flat position, both the first extension 2122 and the second extension 2123 extend downward in the vertical direction, and the extension length of the first extension 2122 is less than the extension length of the second extension 2123.
[0128] Thus, both the first extension segment 2122 and the second extension segment 2123 extend along the second direction, so that the formed guide channel 2121 guides the dirt to the inner wall of the housing 100. Furthermore, the extension length of the first extension segment 2122 is less than the extension length of the second extension segment 2123, and a drain channel is formed between the first extension segment 2122 and the inner wall of the housing 100, so that the dirt in the guide channel 2121 enters the solid cavity 102 through the drain channel.
[0129] Among them, reference Figure 9 As shown, the second separator 220, the first extension 2122, and the second extension 2123 are arranged sequentially along the extension direction of the first separator 210, i.e., sequentially along the first direction. In this way, a sewage discharge channel is formed between the first extension 2122 and the inner wall of the housing 100, located between the guide channel 2121 and the second separator 220, so that the dirt flowing out of the sewage discharge channel can flow directly to the second separator 220, thereby avoiding the extension 212 from obstructing the flow of dirt to the liquid chamber 103.
[0130] In some embodiments, the extension length of the first extension segment 2122 is greater than 0 mm and less than or equal to 200 mm. The extension length of the second extension segment 2123 is greater than 0 mm and less than or equal to 200 mm.
[0131] This ensures that the first extension segment 2122 and the second extension segment 2123 form the guide channel 2121.
[0132] For example, the extension length of the first extension segment 2122 can be 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, 110mm, 120mm, 130mm, 140mm, 150mm, 160mm, 170mm, 180mm, 190mm, 200mm, etc. The extension length of the second extension segment 2123 can be 10mm, 20mm, 30mm, 40mm, 50mm, 60mm, 70mm, 80mm, 90mm, 100mm, 110mm, 120mm, 130mm, 140mm, 150mm, 160mm, 170mm, 180mm, 190mm, 200mm, etc. As long as the extension length of the first extension segment 2122 is less than the extension length of the second extension segment 2123, this embodiment does not impose excessive restrictions in this regard.
[0133] The first extension segment 2122, the second extension segment 2123 and the first separation member 210 can be integrally formed.
[0134] Reference Figure 2 , Figure 3 and Figure 9 As shown, in some embodiments, the second separator 220 is provided with a sewage channel 221, which connects the solid cavity 102 and the liquid cavity 103.
[0135] In this way, after the dirt enters the solid cavity 102, the solid matter in the dirt is left in the solid cavity 102 by the second separator 220, while the sewage in the dirt enters the liquid cavity 103 through the sewage channel 221.
[0136] Reference Figure 2 , Figure 3 and Figure 9 As shown, in some embodiments, a second filter element 222 is also provided on the second separator 220. The second filter element 222 is located in the solid cavity 102 and covers the sewage channel 221.
[0137] In this way, the second filter element 222 can filter out dirt entering the sewage channel 221, so as to block smaller solids in the solid cavity 102.
[0138] For example, the second filter element 222 can be a filter screen or the like.
[0139] Reference Figure 2 and Figure 3 As shown, in some embodiments, the sewage channel 221 extends along the extending direction of the second separator 220. The second separator 220 has an inlet 2211 and an outlet 2212 communicating with the sewage channel 221. The inlet 2211 communicates with the solid cavity 102, and the outlet 2212 communicates with the liquid cavity 103. When the tank 100 is in a flat position, the outlet 2212 is located above the inlet 2211.
[0140] In this way, dirt can enter the sewage channel 221 through the sewage inlet 2211 on the second separator 220, and then enter the liquid chamber 103 through the sewage outlet 2212 on the second separator 220. When the tank 100 is in a horizontal position, the sewage outlet 2212 is located above the sewage inlet 2211, so that there is a certain height difference between the sewage outlet 2212 and the sewage in the liquid chamber 103, making it difficult for sewage in the liquid chamber 103 to backflow into the sewage outlet 2212.
[0141] Specifically, refer to Figure 2 and Figure 3 As shown, the sewage channel 221 extends along the extension direction of the second separator 220, that is, the sewage channel 221 extends along the second direction. When the sewage tank 10 is in a flat position, the sewage inlet channel 110, the sewage outlet 2212 and the sewage outlet 2211 are arranged from top to bottom in the vertical direction (i.e., the second direction).
[0142] Reference Figures 5 to 8 As shown, in some embodiments, the first separator 210 is provided with a baffle 213, which is located inside the exhaust chamber 101, and the baffle 213 and part of the first separator 210 form an exhaust port 201.
[0143] Thus, the vent 201 is formed by the enclosure 213 and the first separator 210. The enclosure 213 is located inside the vent chamber 101. When the sewage tank 10 is not in a flat position, the second separator 220 separates the enclosure 213 from the sewage in the liquid chamber 103. When the sewage tank 10 is in a flat position, the first separator 210 separates the enclosure 213 from the sewage that flows back into the solid chamber 102, thereby preventing sewage from directly entering the vent 201.
[0144] Reference Figure 3 , Figure 5 , Figure 6 and Figure 9 As shown, in some embodiments, the first separator 210 is provided with at least one vent hole 214, which connects the exhaust chamber 101 and the solid chamber 102.
[0145] In this way, after the gas enters the solid cavity 102, it can enter the exhaust cavity 101 through the vent hole 214 on the first separator 210, and then enter the exhaust port 201 from the exhaust cavity 101.
[0146] Specifically, refer to Figure 5 , Figure 6 and Figure 9 As shown, the first separator 210 may be provided with a plurality of vent holes 214 at intervals to expand the flow path of the airflow.
[0147] Reference Figure 5 , Figure 6 and Figure 9 As shown, in some embodiments, the vent 214 and the enclosure portion 213 are spaced apart in the extending direction of the first separator 210.
[0148] In this way, by misaligning the vent 214 with the exhaust port 201 formed by the enclosure 213, the vent 214 and the exhaust port 201 are kept away from each other, so as to prevent sewage from splashing into the exhaust chamber 101 and then directly entering the exhaust port 201.
[0149] Specifically, Figure 5 , Figure 6 and Figure 9 When the sewage tank 10 is in a horizontal position, the vent 201, the air vent, and the second separator 220 are spaced apart along the extension direction (i.e., the first direction) of the first separator 210, with the vent 201 located above the air vent 214. This creates a significant height difference between the vent 201 and the sewage, preventing the sewage from easily rising through the vent chamber 101 and entering the vent 201 during the back-and-forth movement of the sewage tank 10.
[0150] Reference Figures 5 to 9 As shown, in some embodiments, the first separator 210, the second separator 220 and the inner wall of the housing 100 together form an exhaust channel 230, which connects the liquid chamber 103 and the exhaust port 201.
[0151] In this way, a small portion of the gas entering the liquid chamber 103 can enter the exhaust port 201 in the exhaust chamber 101 through the exhaust channel 230 under the action of the negative pressure source.
[0152] During the process of the gas entering the exhaust port 201 through the exhaust channel 230, it can carry the sewage in the solid chamber 102 into the liquid chamber 103, thereby effectively reducing the sewage in the solid chamber 102 and ensuring that the sewage is stored in the liquid chamber 103. This reduces or avoids the sewage surging in the solid chamber 102, and enters the exhaust chamber 101 through the vent 214 on the first separator 210.
[0153] Specifically, refer to Figure 7 and Figure 8 As shown, when the sewage tank 10 is in a flat position, the air inlet of the exhaust channel 230 is positioned close to the sewage inlet channel 110 in the vertical direction (i.e., the second direction). This ensures that the air inlet of the exhaust channel 230 is located above the sewage in the liquid chamber 103, and there is a drop between the air inlet of the exhaust channel 230 and the sewage to prevent the sewage from directly entering the exhaust channel 230 through the air inlet.
[0154] In some embodiments, the minimum cross-sectional area of the exhaust passage 230 is S1, the minimum cross-sectional area of the exhaust port 201 is S2, and 1%≤S1 / (S1+S2)≤60%.
[0155] This ensures that the gas in the exhaust channel 230 can enter the exhaust port 201 under the action of the negative pressure source. Furthermore, as the cross-sectional area of the exhaust channel 230 gradually increases, the flow velocity of the gas through the exhaust channel 230 also decreases accordingly, which can also prevent or reduce the intake of sewage into the exhaust port 201 through the exhaust channel 230.
[0156] For example, the value of S1 / (S1+S2) can be 1%, 10%, 20%, 30%, 40%, 50%, 60%, etc.
[0157] Reference Figure 1 As shown, in some embodiments, the second separator 220 is provided with at least one first baffle 223, which is located inside the liquid chamber 103 and is used to prevent sewage from the liquid chamber 103 from entering the exhaust channel 230.
[0158] In this way, the first baffle 223 is set in correspondence with the exhaust channel 230 so as to prevent sewage from the liquid chamber 103 from entering the exhaust channel 230.
[0159] Furthermore, refer to Figures 5 to 9 As shown, when the sewage tank 10 is in a flat position, in the vertical direction (i.e., the second direction), the first baffle 223 is located below the air inlet of the exhaust channel 230. In this way, the first baffle 223 can suppress the surge in the liquid chamber 103 to prevent sewage in the liquid chamber 103 from splashing into the air inlet of the exhaust channel 230.
[0160] Reference Figure 5 and Figure 9 As shown, there are multiple first baffles 223, which are spaced apart on the second separator 220 to improve the blocking effect on sewage in the liquid chamber 103.
[0161] Specifically, refer to Figure 5 and Figure 9 As shown, there can be two exhaust channels 230, which are arranged on opposite sides of the separation assembly 200 to increase the flow path of gas in the liquid chamber 103.
[0162] Reference Figure 7 and Figure 8 As shown, in some embodiments, at least one second baffle 231 is provided in the exhaust channel 230, the second baffle 231 is used to prevent sewage from the liquid chamber 103 from entering the exhaust port 201.
[0163] In this way, by setting a second baffle 231 in the exhaust channel 230, the sewage entering the exhaust channel 230 is further blocked, and the sewage in the exhaust channel 230 is prevented from being sucked into the exhaust port 201.
[0164] Among them, reference Figure 7 and Figure 8 As shown, there are multiple second baffles 231, which are spaced apart in the exhaust channel 230 along the extension direction (i.e., the first direction) of the first separator 210, so as to improve the blocking effect on the sewage in the exhaust channel 230.
[0165] Reference Figure 7 and Figure 8 As shown, in some embodiments, the exhaust passage 230 extends along the extension direction of the housing 100.
[0166] This extends the path of the exhaust channel 230, allowing the wastewater entering the exhaust channel 230 to remain within it, thus preventing the wastewater from being sucked into the exhaust port 201.
[0167] Specifically, refer to Figures 2 to 8 As shown, when the floor scrubber is working, it generates negative pressure by drawing in air through a negative pressure source. Under the action of the negative pressure source, the dirt enters the dirt inlet channel 110 and then sequentially passes through the dirt inlet connector 211 and the guide channel 2121 into the solid chamber 102. Then, the dirt passes through the second filter element 222 on the second separator 220. The solids in the dirt are blocked in the solid chamber 102, while the wastewater in the dirt passes through the second filter element 222 and enters the liquid chamber 103 through the wastewater channel 221 on the second separator 220.
[0168] Under the influence of the negative pressure source, most of the gas enters the exhaust chamber 101 through the vent 214 on the first separator 210 within the solid chamber 102, and then enters the exhaust port 201. A small portion of the gas enters the liquid chamber 103 through the second filter 222 and the sewage channel 221, and then enters the exhaust port 201 through the exhaust channel 230.
[0169] Reference Figure 1 As shown, the cleaning equipment provided in this application includes a main unit 20 and a wastewater tank 10 as described above, wherein the wastewater tank 10 is detachably connected to the main unit 20.
[0170] Since the cleaning equipment uses the sewage tank 10 in the above embodiment, it also has the advantages and benefits brought by the sewage tank 10, which will not be elaborated further here.
[0171] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of this application, and are not intended to limit them. Although this application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some or all of the technical features therein.
