Wastewater tanks and cleaning equipment

Abstract

This application provides a wastewater tank and cleaning equipment, relating to the field of cleaning device technology. 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 within the tank body, dividing the tank body into a separation chamber, a first exhaust chamber, a solid chamber, and a liquid chamber. The first exhaust chamber, solid chamber, and liquid chamber are respectively connected to the separation chamber, and the solid chamber is connected to the wastewater inlet channel. The separation component has an exhaust port connected to the first exhaust chamber, which is used to connect to a negative pressure source. During the operation of the floor scrubber, regardless of whether the wastewater tank is in a horizontal or horizontal position, the first exhaust chamber and exhaust port inside the wastewater tank are always located above the liquid level, thus creating a certain drop between them. This prevents liquid from easily rising into the first exhaust chamber and then into the exhaust port. Furthermore, the separation component can suppress surges to prevent liquid from splashing into the first exhaust chamber.

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 smart home cleaning appliance that integrates vacuuming, mopping, washing, and self-cleaning functions. It is mainly used for deep cleaning of hard floors (such as tiles, wood floors, marble, etc.).

[0003] In related technologies, floor scrubbers have a wastewater tank and a negative pressure component. The floor scrubber can move back and forth on the surface to be cleaned. By using the negative pressure component to draw air in, a negative pressure is generated inside the floor scrubber, thereby sucking in dirt such as dust, hair, and wastewater 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. The wastewater will then be sucked into the negative pressure component, causing 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 being sucked into a 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 housing and divides the housing into a separation chamber, a first exhaust chamber, a solid chamber, and a liquid chamber. The first exhaust chamber, the solid chamber, and the liquid chamber are respectively connected to the separation chamber. The solid chamber is connected to the sewage inlet channel. The separation component has an exhaust port connected to the first exhaust chamber. The exhaust port is used to connect to a negative pressure source.

[0009] The first exhaust chamber is located on at least one side of the solid chamber, and the liquid chamber, separation chamber and exhaust port are arranged sequentially along the extension direction of the box body; when the box body is in a flat state, the solid chamber and the first exhaust chamber are both located above the separation chamber.

[0010] Thus, during the operation of the floor scrubber, regardless of whether the wastewater tank is in a horizontal or horizontal position, the first exhaust chamber and exhaust port inside the wastewater tank are always located above the liquid level, creating a certain height difference. This prevents the liquid from rising into the first exhaust chamber and then entering the exhaust port. Furthermore, the separation component can suppress surges, preventing liquid from splashing into the first exhaust chamber.

[0011] In one possible implementation, the sewage tank provided in this application further includes a cover, with an installation opening formed at one 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 filter element disposed on the cover, the filter element being used to filter gas discharged through the exhaust port.

[0014] In this way, the filter 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 seal, which is disposed on the separation assembly and abuts against the inner wall of the tank.

[0016] 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.

[0017] 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;

[0018] The second separator surrounds a portion of the first separator, and the second separator abuts against the inner wall of the housing, so that the portion of the first separator, the second separator, and the inner wall of the housing together form a solid cavity.

[0019] Thus, the second separator surrounds the first separator to form a receiving trough for holding solids in the dirt. After the separator assembly is installed into the housing, the second separator abuts against the inner wall of the housing, so that the first separator, the second separator, and the inner wall of the housing together form a solid cavity for collecting solids in the dirt.

[0020] In one possible implementation, the wastewater tank provided in this application has a first separation member with a plurality of filter holes, the filter holes connecting the solid cavity and the separation cavity, for the purpose of blocking solids in the dirt within the solid cavity.

[0021] In this way, the gas entering the solid chamber and the liquid in the dirt can enter the separation chamber through the filter holes, while the solid in the dirt is blocked in the solid chamber.

[0022] In one possible implementation, the wastewater tank provided in this application has at least one vent on the second separator, the vent connecting the solid chamber and the separator, and the vent and the wastewater inlet channel are arranged sequentially along the extension direction of the tank body.

[0023] Thus, by setting vent holes on the second separator, the flow path of airflow in the solid chamber is increased, preventing solids in the dirt from clogging the filter holes and causing airflow obstruction.

[0024] In one possible implementation, the sewage tank provided in this application has a notch on the second separator, the notch connecting the sewage inlet channel and the solid cavity, and the notch and the vent are located on opposite sides of the second separator.

[0025] In this way, the inlet channel can be connected to the solid cavity through the notch. Furthermore, the notch and the vent are located on opposite sides of the second separator to keep the inlet channel and the vent far apart from each other, preventing dirt from being directly sucked into the vent after exiting the inlet channel, which would cause the solid in the dirt to cover the vent and cause blockage.

[0026] In one possible implementation, the sewage tank provided in this application further includes a third separating component, which is disposed on the first separating component. The first separating component, the second separating component, the third separating component, and the inner wall of the tank together form a separation cavity.

[0027] The third separator and the inner wall of the housing together form a liquid cavity, with the separation cavity and the liquid cavity located on opposite sides of the third separator.

[0028] Thus, by setting a third separator to form a separation chamber and a liquid chamber, the separation chamber and the liquid chamber are located on opposite sides of the third separator, and the liquid in the separation chamber enters the liquid chamber through the third separator.

[0029] In one possible implementation, the sewage tank provided in this application further includes at least one fourth separator, which is disposed on the first separator. The fourth separator and the third separator are located on opposite sides of the first separator, and the fourth separator and the second separator are located on the same side of the first separator.

[0030] The fourth separator, the outer wall of the second separator, part of the first separator, and the inner wall of the housing together form the first exhaust chamber.

[0031] Thus, by setting a fourth separator to form a first exhaust chamber, the first exhaust chamber and the solid chamber are located on the same side of the first separator, and the first exhaust chamber and the separator are located on opposite sides of the first separator, so that when the sewage tank is in a flat position, the solid chamber and the first exhaust chamber can both be located above the separator.

[0032] In one possible implementation, the sewage tank provided in this application has at least one exhaust channel on the first separation member, and the exhaust channel connects the separation chamber and the first exhaust chamber.

[0033] In this way, the gas in the separation chamber can enter the first exhaust chamber through the exhaust channel.

[0034] In one possible implementation, the sewage tank provided in this application has a first exhaust chamber surrounding at least two sides of the solid chamber, and at least two exhaust channels corresponding to the first exhaust chamber and the separation chamber.

[0035] Thus, there are at least two first exhaust chambers, which are arranged around at least two sides of the solid cavity. Each first exhaust chamber is connected to the separation chamber and the exhaust port, thereby increasing the gas flow path and avoiding airflow obstruction.

[0036] In one possible implementation, the sewage tank provided in this application has a first air outlet on the first separation component, and the first air outlet is connected to the exhaust port and the first exhaust chamber.

[0037] The second separator is located between the first air outlet and the exhaust channel.

[0038] In this way, the gas in the first exhaust chamber can enter the exhaust port through the first air outlet. Furthermore, the first air outlet and the exhaust channel are positioned on opposite sides of the second separator to keep them far apart, thereby preventing the liquid in the separator from directly entering the first air outlet through the exhaust channel.

[0039] In one possible implementation, the sewage tank provided in this application has a baffle on the first separator, the baffle is located inside the first exhaust chamber, the baffle is connected to the second separator, and the baffle, part of the first separator and part of the second separator together form a first air outlet.

[0040] Thus, the exhaust port is formed by the enclosure, part of the first separation member and part of the second separation member. When liquid accidentally enters the first exhaust chamber, the enclosure can prevent the liquid from entering the first air outlet and the exhaust port.

[0041] In one possible implementation, the sewage tank provided in this application has a third separator connected to a fourth separator, and the third separator, the fourth separator, and the inner wall of the tank together form a liquid cavity;

[0042] The third separator is provided with a sewage channel, which extends to the fourth separator and connects the separation chamber and the liquid chamber.

[0043] Thus, the liquid in the separation chamber can enter the sewage channel through the inlet on the third separator and enter the liquid chamber through the outlet on the fourth separator. When the tank is in a horizontal position, the liquid in the liquid chamber will flow back. Because the outlet is located above the inlet, creating a certain height difference between the outlet and the liquid level in the liquid chamber, the liquid in the liquid chamber does not easily rise to the outlet, causing it to flow back into the separation chamber.

[0044] In one possible implementation, the sewage tank provided in this application has a sewage inlet on the third separating member that communicates with the sewage channel, and a sewage outlet on the fourth separating member that communicates with the sewage channel. The sewage inlet is connected to the separation chamber, and the sewage outlet is connected to the liquid chamber.

[0045] When the container is in a flat position, the drain outlet is located above the inlet.

[0046] Thus, the liquid in the separation chamber can enter the sewage channel through the inlet on the third separator and enter the liquid chamber through the outlet on the fourth separator. When the tank is in a horizontal position, the liquid in the liquid chamber will flow back. Because the outlet is located above the inlet, creating a certain height difference between the outlet and the liquid level in the liquid chamber, the liquid in the liquid chamber does not easily rise to the outlet, causing it to flow back into the separation chamber.

[0047] In one possible implementation, the wastewater tank provided in this application further divides the tank body into a second exhaust chamber, which connects the liquid chamber and the exhaust port, and is located on at least one side of the solid chamber.

[0048] In this way, the negative pressure source can provide negative pressure to the liquid chamber through the second exhaust chamber, so that the liquid in the separation chamber can be drawn into the liquid chamber through the sewage channel, so as to avoid the liquid level in the separation chamber being too high when the sewage tank is in a flat state, which would cause it to enter the first exhaust chamber.

[0049] In one possible implementation, the sewage tank provided in this application further includes at least one fifth separator and at least one sixth separator, with the fifth separator and the sixth separator being connected to each other, the fifth separator being disposed on the first separator, and the sixth separator being disposed on the fourth separator;

[0050] The first separator, the fourth separator, the fifth separator, the sixth separator, and the inner wall of the housing together form the second exhaust chamber.

[0051] Thus, the first separator, the fifth separator, and the inner wall of the housing together form one section of the second exhaust chamber, and the fourth separator, the sixth separator, and the inner wall of the housing together form another section of the second exhaust chamber. The two sections are spliced ​​together to form a complete second exhaust chamber, so as to facilitate the flow between the liquid chamber and the exhaust port.

[0052] In one possible implementation, the sewage tank provided in this application has at least two second exhaust chambers, with at least two second exhaust chambers provided on both sides of the solid chamber.

[0053] Thus, there are at least two second exhaust chambers, which are arranged around at least two sides of the solid chamber. Each second exhaust chamber is connected to the liquid chamber and the exhaust port, thereby increasing the gas flow path and avoiding airflow obstruction.

[0054] In one possible implementation, the sewage tank provided in this application has at least one second air outlet on the first separation member, the second air outlet correspondingly connecting the second exhaust chamber and the exhaust port, and at least one air inlet on the fourth separation member, the air inlet correspondingly connecting the second exhaust chamber and the liquid chamber.

[0055] In this way, the gas in the liquid chamber can enter the second exhaust chamber through the air inlet on the fourth separator, and then enter the exhaust port through the second air outlet on the first separator.

[0056] In one possible implementation, the sewage tank provided in this application has at least one water-blocking part on the fourth separator, the water-blocking part being located inside the liquid chamber and being arranged corresponding to the air inlet.

[0057] When the enclosure is in a flat position, the air inlet is located above the water baffle.

[0058] Thus, when the housing is in a flat position, the water baffle can play a certain blocking role to prevent liquid in the liquid chamber from entering the second exhaust chamber through the air inlet.

[0059] In one possible implementation, the wastewater tank provided in this application further includes at least one detection element, which is disposed on the separation assembly. The detection probe of the detection element is used to detect the liquid level in the liquid chamber. The detection probe of the detection element is disposed correspondingly to the water-blocking part, which separates the detection probe of the detection element from the sewage outlet.

[0060] In this way, the detection probe of the sensor extends into the liquid chamber. When the liquid level in the chamber is too high, the sensor can issue a warning signal to remind the user to clean the wastewater tank. Furthermore, the water-blocking part connects the sensor's detection probe to the drain outlet, thus preventing liquid discharged from the drain outlet from directly hitting the sensor's detection probe and causing it to issue an incorrect warning signal.

[0061] 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.

[0086] To make the objectives, technical solutions, and advantages of this application clearer, the technical solutions in the embodiments of this application will be described in more detail below with reference to the accompanying drawings. In the drawings, the same or similar reference numerals denote the same or similar components or components having the same or similar functions throughout. The described embodiments are some, but not all, embodiments of this application. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this application, and should not be construed as limiting this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without creative effort are within the scope of protection of this application. The embodiments of this application will be described in detail below with reference to the accompanying drawings.

[0087] In the description of this application, it should be noted that, unless otherwise expressly specified and limited, the terms "installation," "connection," and "linking" should be interpreted broadly. For example, they can refer to a fixed connection, an indirect connection through an intermediate medium, or the internal communication between two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this application according to the specific circumstances.

[0088] In the description of this application, it should be understood that the terms "upper", "lower", "front", "back", "vertical", "horizontal", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the accompanying drawings, and are only for the convenience of describing this application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this application.

[0089] The terms "first," "second," and "third" (if any) in the specification, claims, and accompanying drawings of this application are used to distinguish similar objects and are not necessarily used to describe a particular order or sequence. It should be understood that such data can be interchanged where appropriate so that the embodiments of this application described herein can be implemented, for example, in orders other than those illustrated or described herein.

[0090] 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.

[0091] In related technologies, floor scrubbers have a wastewater tank and a negative pressure component. The floor scrubber can move back and forth on the surface to be cleaned. By using the negative pressure component to draw air in, a negative pressure is generated inside the floor scrubber, thereby sucking in dirt such as dust, hair, and wastewater from the surface to be cleaned into the wastewater tank.

[0092] 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. The wastewater will then be sucked into the negative pressure component, causing damage to the negative pressure component.

[0093] 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.

[0094] 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 a separation chamber, a first exhaust chamber, a solid chamber, and a liquid chamber. The first exhaust chamber, solid chamber, and liquid chamber are respectively connected to the separation chamber, and the solid chamber is connected to the wastewater inlet channel. The separation component has an exhaust port connected to the first exhaust chamber, which is used to connect to a negative pressure source. The first exhaust chamber is located on at least one side of the solid chamber, and the liquid chamber, separation chamber, and exhaust port are arranged sequentially along the extension direction of the tank body. When the tank body is in a horizontal position, both the solid chamber and the first exhaust chamber are located above the separation chamber. During the operation of the floor scrubber, regardless of whether the wastewater tank is in a horizontal or horizontal position, the first exhaust chamber and exhaust port inside the wastewater tank are always located above the liquid level, thus creating a certain drop between them, making it difficult for liquid to rise into the first exhaust chamber and then into the exhaust port. Furthermore, the separation component can suppress surges to prevent liquid from splashing into the first exhaust chamber.

[0095] 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.

[0096] It should be noted that the separation chamber 101, the first exhaust chamber 102, the solid chamber 103, the liquid chamber 104, and the second exhaust chamber 105 are formed jointly by the separation assembly 200 and the housing 100. To facilitate understanding of the relative positions of each chamber within the housing 100, in... Figure 4 , Figure 5 , Figure 12 and Figure 13 The diagram shows the position of each cavity on the separation assembly 200.

[0097] Reference Figures 2 to 13 The wastewater tank 10 provided in this embodiment includes a tank body 100 and a separation component 200. A wastewater 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 a separation chamber 101, a first exhaust chamber 102, a solid chamber 103, and a liquid chamber 104. The first exhaust chamber 102, the solid chamber 103, and the liquid chamber 104 are respectively connected to the separation chamber 101. The solid chamber 103 is connected to the wastewater inlet channel 110. The separation component 200 has an exhaust port 201 connected to the first exhaust chamber 102, and the exhaust port 201 is used to connect to a negative pressure source.

[0098] The first exhaust chamber 102 is located on at least one side of the solid chamber 103, and the liquid chamber 104, the separation chamber 101, 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, both the solid chamber 103 and the first exhaust chamber 102 are located above the separation chamber 101.

[0099] 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, which includes both solid and liquid components. Gas enters the negative pressure source through the exhaust port 201.

[0100] Reference Figures 5 to 7 As shown, the arrow pointed to by number a indicates the flow direction of the liquid in the dirt. Under the action of the negative pressure source, external gas and dirt are sucked into the sewage tank 10 through the sewage inlet channel 110. First, they enter the solid chamber 103, where the solids in the dirt remain, while the gas and liquid in the dirt enter the separation chamber 101. Then, the gas and liquid in the dirt are separated in the separation chamber 101. The gas enters the first exhaust chamber 102 and enters the negative pressure source through the exhaust port 201 on the separation component 200, while the liquid flows into the liquid chamber 104.

[0101] Reference Figure 6 As shown, the liquid chamber 104, separation chamber 101, and exhaust port 201 are arranged sequentially along the extension direction of the housing 100. Thus, when the housing 100 is not in a horizontal position (e.g., upright or tilted), the liquid chamber 104, separation chamber 101, and exhaust port 201 are arranged sequentially in the vertical direction. Specifically, when the housing 100 is in a horizontal position, the solid chamber 103 and the first exhaust chamber 102 are both located above the separation chamber 101. This means that when the housing 100 is not in a horizontal position, the solid chamber 103, exhaust chamber, exhaust port 201, and separation chamber 101 are all located above the liquid chamber 104.

[0102] When the casing 100 is not in a horizontal position (e.g., upright or tilted), the liquid in the separation chamber 101 flows entirely into the liquid chamber 104 under the influence of gravity. The exhaust port 201 and the first exhaust chamber 102 are always positioned above the liquid level in the liquid chamber 104, with a certain height difference between them. This prevents the liquid from easily climbing through the first exhaust chamber 102 into the exhaust port 201. Furthermore, during the back-and-forth cleaning process of the floor scrubber, the separation component 200 can suppress the surge generated within the separation chamber 101, preventing the liquid in the separation chamber 101 from directly splashing into the first exhaust chamber 102 and then entering the negative pressure source through the exhaust port 201, which could damage the negative pressure source.

[0103] When the housing 100 is in a horizontal position, the liquid in the separation chamber 101 will flow back, and even some of the liquid in the liquid chamber 104 will flow back into the separation chamber 101, leaving some liquid in the separation chamber 101. Since the solid chamber 103 and the first exhaust chamber 102 are both located above the separation chamber 101, and the exhaust port 201 is also located above the separation chamber 101, the solid chamber 103, the first exhaust chamber 102, and the exhaust port 201 are all above the liquid level in the separation chamber 101. There is a certain height difference between the exhaust port 201 and the liquid level, making it difficult for the liquid to rise into the first exhaust chamber 102 and then into the exhaust port 201. Furthermore, during the back-and-forth pushing and pulling cleaning process of the floor scrubber, the separation component 200 can suppress the surge generated in the separation chamber 101 to prevent the liquid in the separation chamber 101 from directly splashing into the first exhaust chamber 102.

[0104] When the housing 100 is in a flat position, the solid cavity 103 is located above the separation cavity 101, so that there is a certain height difference between the solid cavity 103 and the separation cavity 101. The liquid in the solid cavity 103 can enter the separation cavity 101 under the action of gravity, and the liquid in the separation cavity 101 can also be prevented from flowing back into the solid cavity 103.

[0105] Furthermore, the first exhaust chamber 102 is located on at least one side of the solid cavity 103, which makes full use of the internal space of the housing 100 to make the overall structure more compact. It is understood that the first exhaust chamber 102 may be located only on one side of the solid cavity 103; the first exhaust chamber 102 may also be located on adjacent sides or opposite sides of the solid cavity 103; the first exhaust chamber 102 may also be arranged around the periphery of the solid cavity 103. This application embodiment does not impose further limitations in this regard.

[0106] In this way, during the operation of the floor scrubber, regardless of whether the wastewater tank 10 is in a horizontal or horizontal position, the first exhaust chamber 102 and the exhaust port 201 inside the wastewater tank 10 are always located above the liquid level, thus creating a certain height difference with the liquid level. This prevents the liquid from rising and entering the first exhaust chamber 102, and from there entering the exhaust port 201. Furthermore, the separation component 200 can suppress surges to prevent liquid from splashing into the first exhaust chamber 102.

[0107] To facilitate understanding of directions, an XY plane coordinate system is established in the accompanying drawings. The direction of the X-axis is the first direction, and the direction of the Y-axis is the second direction. The first direction and the second direction are perpendicular. The extension direction of the tank 100 is the first direction, that is, the liquid chamber 104, the separation chamber 101, and the exhaust port 201 are arranged sequentially along the first direction. When the sewage tank 10 is in an upright state, the first direction is the vertical direction. The solid chamber 103 and the first exhaust chamber 102 are arranged sequentially along the second direction. When the sewage tank 10 is in a horizontal state, the second direction is the vertical direction.

[0108] Reference Figures 2 to 4 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.

[0109] In this way, the cover 300 is placed over the mounting opening of the box 100 to form a sealed inner cavity.

[0110] 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.

[0111] Reference Figures 4 to 6 As shown, in some embodiments, the sewage tank 10 provided in this application embodiment further includes a filter element 400, which is disposed on the cover 300 and is used to filter the gas discharged through the exhaust port 201.

[0112] In this way, the 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.

[0113] For example, the 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.

[0114] Reference Figure 3 As shown, in some embodiments, the sewage tank 10 provided in this application embodiment further includes a sealing element 500, which is disposed on the separation component 200 and abuts against the inner wall of the tank body 100.

[0115] In this way, the gap between the separation assembly 200 and the housing 100 is filled by the seal 500 to ensure the sealing performance between the separation assembly 200 and the housing 100.

[0116] Furthermore, a seal 500 can also be provided between the cover 300 and the box 100 to prevent dirt from leaking out of the box 100.

[0117] For example, the seal 500 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.

[0118] Reference Figures 4 to 7 As shown, in some embodiments, the separation assembly 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 extending along the extending direction of the housing 100. The second separation member 220 surrounds a portion of the first separation member 210 and abuts against the inner wall of the housing 100, so that the portion of the first separation member 210, the second separation member 220, and the inner wall of the housing 100 together form a solid cavity 103.

[0119] Thus, the second separator 220 surrounds the first separator 210 to form a receiving groove for holding solids in the dirt. After the separator assembly 200 is installed inside the housing 100, the second separator 220 abuts against the inner wall of the housing 100, so that the first separator 210, the second separator 220 and the inner wall of the housing 100 together form a solid cavity 103 for collecting solids in the dirt.

[0120] Reference Figure 4 and Figure 6 As shown, when the housing 100 is in a flat position, the opening of the receiving groove formed by the second separating member 220 and the first separating member 210 faces upward. When the housing 100 is full of dirt, the housing 100 can be tilted and the separating component 200 can be pulled out from the housing 100. In this way, the solids in the dirt are collected in the receiving groove of the separating component 200, and the liquids in the dirt are collected in the housing 100, so that the solids and liquids in the dirt can be separated and cleaned later.

[0121] Specifically, a sealing element 500 may be provided on the second separator 220 to fill the gap between the second separator 220 and the housing 100.

[0122] Reference Figure 4 and Figure 8 As shown, in some embodiments, the sewage tank 10 provided in this application has a plurality of filter holes 211 on the first separation member 210. The filter holes 211 connect the solid cavity 103 and the separation cavity 101 to block the solids in the dirt in the solid cavity 103.

[0123] In this way, the gas entering the solid cavity 103 and the liquid in the dirt can enter the separation cavity 101 through the filter hole 211, while the solid in the dirt is blocked in the solid cavity 103.

[0124] The filter hole 211 is located on the first separator 210, that is, the filter hole 211 is located at the bottom of the solid cavity 103 (i.e., the receiving tank), which can prevent liquid in the dirt from remaining in the solid cavity 103.

[0125] Reference Figure 5 and Figure 9 As shown, in some embodiments, the second separator 220 is provided with at least one vent 221, the vent 221 connecting the solid cavity 103 and the separation cavity 101, and the vent 221 and the sewage inlet channel 110 are arranged sequentially along the extension direction of the box body 100.

[0126] In this way, by providing a vent 221 on the second separator 220, the flow path of the airflow in the solid cavity 103 is increased, and the solids in the dirt are prevented from clogging the filter hole 211, which would cause the airflow to be obstructed.

[0127] The vent 221 is located on the second separator 220, specifically on the side wall of the solid cavity 103 (i.e., the receiving groove). This prevents solids in the dirt from clogging the vent 221. Further, refer to... Figure 4 and Figure 5 As shown, the number of vents 221 can be set to multiple, and the vents are elongated holes to increase the air outlet area and further avoid blockage.

[0128] Reference Figure 4 , Figure 6 and Figure 10 As shown, in some embodiments, the second separator 220 is provided with a notch 222, which connects the sewage inlet channel 110 and the solid cavity 103. The notch 222 and the vent 221 are located on opposite sides of the second separator 220.

[0129] In this way, the sewage inlet channel 110 can communicate with the solid cavity 103 through the notch 222. Furthermore, the notch 222 and the vent 221 are located on opposite sides of the second separator 220, so as to keep the sewage inlet channel 110 and the vent 221 far apart from each other, to prevent dirt from being directly sucked into the vent 221 after it comes out of the sewage inlet channel 110, which would cause the solid in the dirt to cover the vent 221 and cause blockage.

[0130] The sewage inlet channel 110 can be inserted into the notch 222, and the dirty outlet of the sewage inlet channel 110 extends into the solid cavity 103, so that the sewage inlet channel 110 can be connected to the solid cavity 103, thus eliminating the cumbersome assembly process.

[0131] Furthermore, the notch 222 is provided on the second separator 220, so that when the sewage tank 10 is in a flat position, the sewage inlet channel 110 is located in the top region of the solid cavity 103. In this way, after the dirt is discharged from the sewage inlet channel 110, under the action of gravity, the dirt will move towards the filter hole 211 at the bottom of the solid cavity 103, so as to prevent the dirt from being directly sucked into the vent 221.

[0132] Reference Figure 5 , Figure 9 and Figure 13 As shown, the arrow indicated by number b indicates the direction of gas flow through vent 221. The gas in solid chamber 103 enters separation chamber 101 through vent 221, then flows sequentially through first exhaust chamber 102 and exhaust port 201, and finally enters negative pressure source through filter 400 on cover 300.

[0133] Reference Figure 4 , Figure 11 and Figure 12 As shown, the separation assembly 200 further includes a third separation member 230, which is disposed on the first separation member 210. The first separation member 210, the second separation member 220, and the third separation member 230, together with the inner wall of the housing 100, form a separation cavity 101. The third separation member 230, together with the inner wall of the housing 100, forms a liquid cavity 104. The separation cavity 101 and the liquid cavity 104 are located on both sides of the third separation member 230.

[0134] Thus, by setting the third separator 230 to form a separation chamber 101 and a liquid chamber 104, the separation chamber 101 and the liquid chamber 104 are located on opposite sides of the third separator 230, and the liquid in the separation chamber 101 enters the liquid chamber 104 through the third separator 230.

[0135] Specifically, refer to Figure 4 , Figure 6 and Figure 12 As shown, the second separating member 220 and the third separating member 230 both extend along the second direction and are disposed on opposite sides of the first separating member 210, so that the formed separating cavity 101 and solid cavity 103 are located on opposite sides of the first separating member 210.

[0136] Reference Figure 4 , Figure 11 and Figure 12As shown, the separation assembly 200 further includes at least one fourth separation member 240, which is disposed on the first separation member 210. The fourth separation member 240 and the third separation member 230 are located on opposite sides of the first separation member 210, and the fourth separation member 240 and the second separation member 220 are located on the same side of the first separation member 210. The outer walls of the fourth separation member 240 and the second separation member 220, a portion of the first separation member 210, and the inner wall of the housing 100 together form the first exhaust chamber 102.

[0137] In this way, by setting the fourth separator 240 to form the first exhaust chamber 102, the first exhaust chamber 102 and the solid chamber 103 are located on the same side of the first separator 210, and the first exhaust chamber 102 and the separator 101 are located on opposite sides of the first separator 210, so that when the sewage tank 10 is in a flat state, the solid chamber 103 and the first exhaust chamber 102 can both be located above the separator 101.

[0138] Specifically, refer to Figure 4 , Figure 6 and Figure 12 As shown, the fourth separator 240 and the third separator 230 both extend along the second direction. The fourth separator 240 can be connected to the third separator 230 so that the third separator 230, the fourth separator 240 and the inner wall of the housing 100 together form a large liquid cavity 104. Thus, the separation cavity 101, the solid cavity 103 and the first exhaust cavity 102 are all located on the same side of the fourth separator 240 and the third separator 230 as a whole, and are located on opposite sides of the liquid cavity 104 as a whole of the fourth separator 240 and the third separator 230.

[0139] It is understood that at least one fourth separator 240, and the number of fourth separators 240 can be one, to form one first exhaust chamber 102. The number of fourth separators 240 can be multiple, to form multiple first exhaust chambers 102, thereby increasing the gas flow path.

[0140] Reference Figure 4 , Figure 5 , Figure 8 and Figure 9 As shown, the first separator 210 is provided with at least one exhaust channel, which connects the separator 101 and the first exhaust chamber 102.

[0141] In this way, the gas in the separation chamber 101 can enter the first exhaust chamber 102 through the exhaust channel.

[0142] Reference Figure 5 , Figure 9 and Figure 13As shown, the arrow indicated by number b indicates the direction of gas flow through vent 221. The gas in solid chamber 103 enters separation chamber 101 through vent 221, then flows sequentially through exhaust channel, first exhaust chamber 102, exhaust port 201, and finally enters negative pressure source through filter 400 on cover 300.

[0143] It is understandable that there is at least one exhaust channel. The number of exhaust channels can be one, two or more, as long as they correspond one-to-one with the number of first exhaust chambers 102.

[0144] Reference Figure 8 and Figure 9 As shown, in some embodiments, the first exhaust chamber 102 is disposed around at least two sides of the solid chamber 103, and the number of exhaust channels is at least two, with the exhaust channels correspondingly connecting the first exhaust chamber 102 and the separation chamber 101.

[0145] Thus, there are at least two first exhaust chambers 102, which are arranged around at least two sides of the solid cavity 103. Each first exhaust chamber 102 is connected to the separation cavity 101 and the exhaust port 201, thereby increasing the flow path of the gas and avoiding airflow obstruction.

[0146] Specifically, refer to Figure 4 , Figure 8 and Figure 9 As shown, there are two fourth separators 240. The two fourth separators 240 are located on both sides of the notch 222 on the second separator 220, so as to form two first exhaust chambers 102 located on opposite sides of the solid cavity 103. The first separator 210 is provided with two exhaust through holes 212.

[0147] Reference Figure 4 , Figure 8 and Figure 9 As shown, in some embodiments, the first separator 210 is provided with a first air outlet 213, the first air outlet 213 connects the exhaust port 201 and the first exhaust chamber 102, and the second separator 220 is located between the first air outlet 213 and the exhaust channel.

[0148] In this way, the gas in the first exhaust chamber 102 can enter the exhaust port 201 through the first air outlet 213. Furthermore, the first air outlet 213 and the exhaust channel are positioned on opposite sides of the second separator 220 to keep them far apart, so as to prevent the liquid in the separator 101 from directly entering the first air outlet 213 through the exhaust channel.

[0149] Reference Figure 5 , Figure 9 and Figure 13As shown, the arrow pointed to by serial number b indicates the direction of gas flow through vent 221. The gas in solid cavity 103 enters separation cavity 101 through vent 221, and then flows sequentially through exhaust channel, first exhaust cavity 102, first air outlet 213, exhaust port 201, and finally enters negative pressure source through filter 400 on cover 300.

[0150] Reference Figure 4 , Figure 12 and Figure 13 As shown, in some embodiments, the first separator 210 is provided with a baffle 214, which is located inside the first exhaust chamber 102. The baffle 214 is connected to the second separator 220, and the baffle 214, part of the first separator 210 and part of the second separator 220 together form the first air outlet 213.

[0151] Thus, the exhaust port 201 is formed by the enclosure part 214, part of the first separation member 210 and part of the second separation member 220. When liquid accidentally enters the first exhaust chamber 102, the enclosure part 214 can prevent the liquid from entering the first air outlet 213 and the exhaust port 201.

[0152] Reference Figure 4 , Figure 12 and Figure 13 As shown, the enclosure 214 extends along the second direction. When the sewage tank 10 is in a flat position, the enclosure 214 extends upward in the vertical direction. Even if liquid enters the first exhaust chamber 102, there is still a certain height difference between the liquid and the first air outlet 213, so that the liquid is not easy to climb up the enclosure 214 and enter the first air outlet 213.

[0153] Reference Figure 4 , Figure 6 and Figure 11 As shown, in some embodiments, the third separator 230 is connected to the fourth separator 240, and the third separator 230, the fourth separator 240 and the inner wall of the housing 100 together form a liquid cavity 104. A sewage channel 231 is provided on the third separator 230, and the sewage channel 231 extends to the fourth separator 240, and the sewage channel 231 connects the separator 101 and the liquid cavity 104.

[0154] In this way, the liquid in the separation chamber 101 can flow into the liquid chamber 104 through the sewage channel 231 on the third separation member 230 and the fourth separation member 240.

[0155] Reference Figure 4 , Figure 6 and Figure 11As shown, in some embodiments, the third separator 230 is provided with an inlet 232 communicating with the sewage channel 231, and the fourth separator 240 is provided with a outlet 241 communicating with the sewage channel 231. The inlet 232 communicates with the separation chamber 101, and the outlet 241 communicates with the liquid chamber 104. When the housing 100 is in a flat position, the outlet 241 is located above the inlet 232. (Refer to...) Figure 7 As shown, the arrow pointed to by number a indicates the direction of liquid flow in the dirt.

[0156] In this way, the liquid in the separation chamber 101 can enter the sewage channel 231 through the inlet 232 on the third separator 230, and enter the liquid chamber 104 through the outlet 241 on the fourth separator 240. When the tank 100 is in a horizontal position, the liquid in the liquid chamber 104 will flow back. Because the outlet 241 is located above the inlet 232, creating a certain height difference between the outlet 241 and the liquid level in the liquid chamber 104, the liquid in the liquid chamber 104 will not easily rise into the outlet 241, causing it to flow back into the separation chamber 101.

[0157] Reference Figure 6 and Figure 7 As shown, the sewage channel 231 extends along the second direction. When the sewage tank 10 is in a flat position, the sewage channel 231 extends vertically, and the sewage outlet 241 is located above the sewage inlet 232 in the vertical direction.

[0158] Reference Figure 4 , Figure 8 and Figure 12 As shown, the separation component 200 further divides the interior of the housing 100 into a second exhaust chamber 105, which connects the liquid chamber 104 and the exhaust port 201. The second exhaust chamber 105 is located on at least one side of the solid chamber 103.

[0159] In this way, the negative pressure source can provide negative pressure to the liquid chamber 104 through the second exhaust chamber 105, so that the liquid in the separation chamber 101 can be drawn into the liquid chamber 104 through the sewage channel 231, so as to avoid the liquid level in the separation chamber 101 being too high when the sewage tank 10 is in a flat state, which would cause it to enter the first exhaust chamber 102.

[0160] Reference Figure 5 and Figure 13As shown, the arrow indicated by number c indicates the flow direction of gas through the second exhaust chamber 105. Since both the first exhaust chamber 102 and the second exhaust chamber 105 are connected to the exhaust port 201, under the action of the negative pressure source, the gas in the separation chamber 101 will be split. One part of the gas (such as the gas indicated by the arrow in number b) directly enters the first exhaust chamber 102, while the other part of the gas (such as the gas indicated by the arrow in number c) enters the liquid chamber 104 through the sewage channel 231, and then enters the second exhaust chamber 105. Finally, the two parts of the gas converge at the exhaust port 201 and flow to the negative pressure source through the filter element 400 on the cover 300.

[0161] The second exhaust chamber 105 is located on at least one side of the solid cavity 103, which makes full use of the internal space of the housing 100 and makes the overall structure more compact. It is understood that the second exhaust chamber 105 may be located only on one side of the solid cavity 103; the second exhaust chamber 105 may also be located on adjacent sides or opposite sides of the solid cavity 103; the second exhaust chamber 105 may also be arranged around the periphery of the solid cavity 103. This application embodiment does not impose further limitations in this regard.

[0162] Reference Figure 4 , Figure 8 and Figure 12 As shown, in some embodiments, the separation assembly 200 further includes at least one fifth separation member 250 and at least one sixth separation member 260, with the fifth separation member 250 and the sixth separation member 260 correspondingly connected. The fifth separation member 250 is disposed on the first separation member 210, and the sixth separation member 260 is disposed on the fourth separation member 240. The first separation member 210, the fourth separation member 240, the fifth separation member 250, the sixth separation member 260, and the inner wall of the housing 100 together form the second exhaust chamber 105.

[0163] Thus, the first segment of the second exhaust chamber 105 is formed by the first separating member 210, the fifth separating member 250 and the inner wall of the housing 100, and the second segment of the second exhaust chamber 105 is formed by the fourth separating member 240, the sixth separating member 260 and the inner wall of the housing 100. The two segments are spliced ​​together to form a complete second exhaust chamber 105, so as to facilitate the flow between the liquid chamber 104 and the exhaust port 201.

[0164] Specifically, the fifth separating member 250 extends along the extending direction of the first separating member 210 and is disposed at the edge of the first separating member 210; the sixth separating member 260 extends along the extending direction of the fourth separating member 240 and is disposed at the edge of the fourth separating member 240, so as to make the overall structure more compact.

[0165] Furthermore, referring to Figure 4 and Figure 12As shown, the sixth separator 260 is disposed on the fourth separator 240. When the sewage tank 10 is lying down, the fourth separator 240 is located above the third separator 230. Thus, the gas inlet of the second exhaust chamber 105 formed by the sixth separator 260 is also located above the liquid level in the liquid chamber 104, so as to prevent the liquid in the liquid chamber 104 from flowing back into the second exhaust chamber 105 when the sewage tank 10 is lying down.

[0166] It is understood that at least one fifth separator 250 and at least one sixth separator 260 may be provided, with one fifth separator 250 and one sixth separator 260 each, to form one second exhaust chamber 105. Alternatively, there may be multiple fifth separators 250 and multiple sixth separators 260, with each fifth separator 250 and the sixth separator 260 arranged in a one-to-one correspondence to form multiple second exhaust chambers 105, thereby increasing the gas flow path.

[0167] Reference Figure 4 , Figure 8 and Figure 12 As shown, in some embodiments, there are at least two second exhaust chambers 105, and at least two sides of the solid cavity 103 are provided with second exhaust chambers 105.

[0168] Thus, there are at least two second exhaust chambers 105, which are arranged around at least two sides of the solid chamber 103. Each second exhaust chamber 105 is connected to the liquid chamber 104 and the exhaust port 201, thereby increasing the gas flow path and avoiding airflow obstruction.

[0169] Specifically, refer to Figure 4 and Figure 9 As shown, there can be two first exhaust chambers 102 and two second exhaust chambers 105. The two first exhaust chambers 102 are located on opposite sides of the solid cavity 103, and the two second exhaust chambers 105 are located on opposite sides of the solid cavity 103. Each first exhaust chamber 102 is correspondingly arranged with each second exhaust chamber 105, so as to make the overall structure more compact.

[0170] Reference Figure 13 As shown, in some embodiments, the first separator 210 is provided with at least one second air outlet 215, which is connected to the second exhaust chamber 105 and the exhaust port 201. The fourth separator 240 is provided with at least one air inlet 242, which is connected to the second exhaust chamber 105 and the liquid chamber 104.

[0171] In this way, the gas in the liquid chamber 104 can enter the second exhaust chamber 105 through the air inlet 242 on the fourth separator 240, and then enter the exhaust port 201 through the second air outlet 215 on the first separator 210.

[0172] The air inlet 242 is located on the fourth separator 240. Since the fourth separator 240 is located above the third separator 230 when the sewage tank 10 is lying down, the air inlet 242 on the fourth separator 240 is also located above the liquid level in the liquid chamber 104, so as to prevent the liquid in the liquid chamber 104 from flowing back into the second exhaust chamber 105 through the air inlet 242 when the sewage tank 10 is lying down.

[0173] It is understandable that there is at least one second air outlet 215 and at least one air inlet 242. The number of the second air outlet 215 and the air inlet 242 can be one or more, as long as they correspond to the number of the second exhaust chambers 105.

[0174] Reference Figure 4 , Figure 11 and Figure 12 As shown, the fourth separator 240 is provided with at least one water-blocking part 243, which is located inside the liquid chamber 104 and is correspondingly arranged with the air inlet 242. When the housing 100 is in a flat position, the air inlet 242 is located above the water-blocking part 243.

[0175] In this way, when the housing 100 is in a flat position, the water baffle 243 can play a certain blocking role to prevent the liquid in the liquid chamber 104 from entering the second exhaust chamber 105 through the air inlet 242.

[0176] It is understandable that there is at least one water-blocking part 243. The number of water-blocking parts 243 can be one or more, as long as they correspond to the number of air inlets 242.

[0177] Reference Figure 4 and Figure 5 As shown, in some embodiments, the sewage tank 10 provided in this application embodiment further includes at least one detection element 600. The detection element 600 is disposed on the separation component 200. The detection probe of the detection element 600 is used to detect the liquid level in the liquid chamber 104. The detection probe of the detection element 600 is correspondingly disposed with the water blocking part 243. The water blocking part 243 separates the detection probe of the detection element 600 from the sewage outlet 241.

[0178] In this way, the detection probe of the detection element 600 extends into the liquid chamber 104. When the liquid level in the liquid chamber 104 is too high, the detection element 600 can issue a warning signal to remind the user to clean the dirt in the sewage tank 10. Furthermore, the water-blocking part 243 connects the detection probe of the detection element 600 to the drain outlet 241, thus preventing liquid discharged from the drain outlet 241 from directly hitting the detection probe of the detection element 600 and causing the detection element 600 to issue an incorrect warning signal.

[0179] For example, the detection element 600 can be a liquid level monitor commonly used in the prior art, and this application embodiment does not impose too many restrictions on it.

[0180] 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.

[0181] 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.

[0182] 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. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the scope of the technical solutions of the embodiments of this application.
