[0024] The supporting part abuts against the inner wall of the box body to separate the box body into a sewage chamber and a mixing chamber.

[0025] In this way, when sewage is sprayed out from the sewage channel, it can be blocked by the water guide body, preventing the sewage from being sprayed directly on the inner wall of the box body, causing dirt and water stains to stick to the inner wall of the box body and be difficult to clean.

[0026] In a possible implementation, the sewage tank provided by the present application, the water retaining member comprises a first water retaining portion and a second water retaining portion which are arranged in sequence, the first water retaining portion is connected to the cover body, and the first water retaining portion abuts against the inner wall of the box body;

[0027] The second water retaining part is connected to the supporting part.

[0028] In this way, the first water retaining part is close to the air outlet channel, and the sewage surge is suppressed by the first water retaining part to prevent the sewage from directly splashing into the air outlet channel, and the second water retaining part blocks part of the sewage from flowing into the air outlet cavity along the water guide body.

[0029] In a possible implementation, the sewage tank provided in the present application has a support tube in the tank body, the inner wall of the support tube forms a sewage channel, and the support part is inserted into the support tube.

[0031] In a possible implementation, in the sewage tank provided in the present application, a first filter portion is disposed on the support portion, the first filter portion corresponds to the sub-mixing chamber, and the first filter portion is used to filter impurities in the sewage entering the sewage chamber.

[0032] In this way, when the sewage flows along the water guide body to the sewage chamber in the sub-mixing chamber, the solid impurities in the sewage fall on the first filter part, and the sewage enters the sewage chamber to separate the solid impurities in the sewage, making it convenient to subsequently treat the sewage and solid impurities in the sewage tank separately.

[0033] In a possible implementation, the sewage tank provided in the present application has a second filter portion disposed on the cover, and the second filter portion is used to filter the gas discharged from the air outlet channel.

[0034] In this way, after the airflow carries the solid impurities from the air outlet cavity into the air outlet channel, the solid impurities can be intercepted by the second filter part to prevent the solid impurities from entering the dust collection component in the cleaning device and causing damage to it.

[0035] In a possible implementation, the sewage tank provided in the present application further includes at least one sealing member, and the sealing member is disposed at at least one of between the cover body and the tank body and between the tank body and the support portion.

The embodiments of the present application are described in detail below in conjunction with the drawings.

[0056] In the description of this application, it should be noted that, unless otherwise clearly specified and limited, the terms "installed", "connected", and "connected" should be understood in a broad sense, for example, it can be a fixed connection, or it can be an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements.

[0058] The terms "first", "second", "third" (if any) in the specification and claims of this application and the above-mentioned drawings are used to distinguish similar objects, and are not necessarily used to describe a specific order or sequence. It should be understood that the numbers used in this way can be interchanged where appropriate, so that the embodiments of the application described herein can be implemented in an order other than those illustrated or described herein, for example.

[0059] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover a non-exclusive inclusion, for example, a process, method, system, product, or display comprising a series of steps or elements is not necessarily limited to those steps or elements explicitly listed, but may include other steps or elements not explicitly listed or inherent to such process, method, product, or display.

[0060] In the related art, when using a floor scrubber to clean low places such as under a sofa or under a bed, the floor scrubber needs to be laid flat at 180 degrees as a whole and extended under the sofa or under the bed to clean by pushing and pulling.

[0061] However, when the sewage tank of the floor scrubber is lying flat and being pushed and pulled, the sewage will hit the top of the sewage tank due to the inertia of pushing and pulling, causing sewage surges and splashes. At this time, due to the action of the airflow, water will enter the air outlet with the airflow, causing water to spray from the air outlet, and enter the sewage suction motor from the air outlet, contaminating the sewage suction motor, causing the performance of the sewage suction motor to deteriorate or be damaged.

[0062] In view of the above problems, the present application provides a sewage tank and a cleaning device. When the sewage tank is lying flat, the sub-mixing chamber is located below the air outlet chamber, sewage enters the sub-mixing chamber from the sewage chamber, and a water retaining member suppresses sewage surges to prevent sewage from directly splashing into an air outlet channel connected to the air outlet chamber; the airflow entering the sub-mixing chamber enters the air outlet chamber through a connecting port provided on the water retaining member, and then enters the air outlet channel through the air outlet chamber.

[0063] The specific implementation of the sewage tank and the cleaning equipment provided in the embodiments of the present application are described in detail below with reference to the accompanying drawings.

[0064] Reference Figures 1 to 6 As shown, the sewage tank provided in the present application includes a tank body 100 , a cover body 200 and a water guide 300 .

[0065] The water guide 300 is disposed on the cover 200 , which is covered on the box 100 . The water guide 300 is located in the box 100 and divides the box 100 into a sewage chamber 110 and a mixing chamber 120 . A sewage channel 130 is disposed in the box 100 .

[0066] A water blocking member 400 is provided on the water guiding member 300, and the water blocking member 400 divides the mixing chamber 120 into an air outlet chamber 121 and a sub-mixing chamber 122. A connecting port 410 connecting the air outlet chamber 121 and the sub-mixing chamber 122 is provided on the water blocking member 400, and the connecting port 410 faces away from the cover body 200. An air outlet channel 500 connected to the air outlet chamber 121 is provided on the cover body 200, and the sewage channel 130 is connected to the sub-mixing chamber 122.

[0067] The water blocking member 400 is configured to prevent sewage from entering the air outlet channel 500 from the sub-mixing chamber 122 when the box body 100 lies flat.

[0068] It should be understood that the sewage tank provided in the present application is mainly used in a cleaning device, which may be a floor scrubber. The floor scrubber may include a dust suction component, which is used to provide suction to suck away sewage from the surface to be cleaned through negative pressure, and the sewage tank is used to recycle the sewage.

[0069] Reference Figure 1 , Figure 2 and Figure 3 As shown, when the sewage tank is in an upright state, the mixing chamber 120 is located above the sewage chamber 110, and the sewage enters the mixing chamber 120 in the box body 100 through the sewage channel 130, and then flows into the sewage chamber 110. The airflow in the box body 100 is sucked in by the dust suction component, and then enters the dust suction component through the mixing chamber 120 through the air outlet channel 500.

[0070] Reference Figure 1 , Figure 2 and Figure 4 As shown, when the floor scrubber is laid flat at 180 degrees to clean low places such as under a sofa or under a bed, the sewage tank is also laid flat. At this time, the sewage in the sewage chamber 110 enters the mixing chamber 120. When the floor scrubber is pushed or pulled, the sewage will hit the cover 200 due to the inertia of pushing and pulling, causing the sewage to surge and splash.

[0071] In order to prevent the sewage from entering the air outlet channel 500 due to the push-pull inertia and then entering the dust collection assembly, the present application sets a water retaining member 400 on the water guide member 300, and the water retaining member 400 separates the mixing chamber 120 into a sub-mixing chamber 122 and an air outlet chamber 121. When the box body 100 lies flat, the sub-mixing chamber 122 is located below the air outlet chamber 121. In this way, the sewage enters the sub-mixing chamber 122 from the sewage chamber 110. Since the air outlet channel 500 connected to the air outlet chamber 121 is separated from the sewage by the water retaining member 400, and the water retaining member 400 reduces the surge space of the sewage, the surge is suppressed, and the sewage cannot directly splash into the air outlet channel 500, resulting in water spraying from the air outlet channel 500.

[0072] And, refer to Figure 3 , Figure 4 and Figure 6 As shown, a connecting port 410 connecting the air outlet chamber 121 and the sub-mixing chamber 122 is opened on the water blocking member 400. The airflow sucked into the box body 100 through the dust collection assembly can enter the air outlet chamber 121 from the sub-mixing chamber 122 through the connecting port 410, and then enter the air outlet channel 500 through the air outlet chamber 121.

[0073] The sewage tank provided in the present application includes a box body 100, a cover body 200 and a water guide member 300, the water guide member 300 is arranged on the cover body 200, and a water retaining member 400 is arranged on the water guide member 300, the box body 100 is divided into a sewage chamber 110 and a mixing chamber 120 by the water guide member 300, and the mixing chamber 120 is divided into an air outlet chamber 121 and the mixing chamber 120 by the water retaining member 400; when the box body 100 is lying flat, the sub-mixing chamber 122 is located below the air outlet chamber 121, and the sewage enters the sub-mixing chamber 122 from the sewage chamber 110, and the water retaining member 400 suppresses the sewage surge to prevent the sewage from directly splashing into the air outlet channel 500 connected to the air outlet chamber 121; the airflow entering the sub-mixing chamber 122 enters the air outlet chamber 121 through the connecting port 410 opened on the water retaining member 400, and then enters the air outlet channel 500 through the air outlet chamber 121.

[0074] Reference Figure 2 and Figure 6 As shown, in a possible implementation, the communication port 410 is a notch provided on the water retaining member 400 , and the opening of the notch faces the inner wall of the box body 100 .

[0075] In this way, the water retaining member 400 is sealed against the inner wall of the box body 100, and the notch of the water retaining member 400 and the inner wall of the box body 100 are surrounded to form a communication port 410. The airflow entering the sub-mixing chamber 122 can enter the air outlet chamber 121 from the notch along the inner wall of the box body 100, so that the airflow enters the air outlet chamber 121 more smoothly.

[0076] Among them, refer to Figure 1 , Figure 3 and Figure 4 As shown, a guide structure may be provided in the box 100 to guide the airflow in the sub-mixing chamber 122 to prevent airflow turbulence. For example, the box 100 may be cylindrical, and the airflow is guided by the arc structure of the inner wall of the box 100.

[0077] Further, refer to Figure 2 and Figure 6 As shown, the notch is located at the end of the water retaining member 400 facing away from the cover body 200 .

[0078] In this way, the notch is kept away from the air outlet channel 500 provided on the cover body 200. When the box body 100 is laid flat, even if the sewage surges and splashes, causing a small amount of sewage to be sprayed into the air outlet chamber 121, it cannot directly enter the air outlet channel 500 under the action of the airflow, but will return to the sub-mixing chamber 122 from the notch along the water retaining member 400.

[0079] Reference Figure 1 , Figure 2 and Figure 6As shown, in a possible implementation, the number of the water retaining members 400 is at least two, and each water retaining member 400 is located on both sides of the water guiding member 300 .

[0080] In this way, the two water retaining members 400 divide the mixing chamber 120 into the air outlet chamber 121 and the sub-mixing chamber 122. When the box body 100 lies flat, the sewage and the air outlet channel 500 are located on opposite sides of the two water retaining members 400. Both water retaining members 400 are provided with connecting ports 410 to increase the flow channel of the airflow, so that the airflow quickly enters the air outlet chamber 121, and avoids the increase of air pressure in the sub-mixing chamber 122.

[0081] The number of the water retaining member 400 is at least two, for example, referring to Figure 1 As shown, there may be two water retaining members 400, and the two water retaining members 400 may be symmetrically arranged on two opposite sides of the water guiding member 300; the water retaining members 400 may also be three water retaining members 400, two of the three water retaining members 400 are located on the same side of the water guiding member 300, and the other is located on the other side opposite to the water guiding member 300, so as to separate the mixing chamber 120 into the air outlet chamber 121 and the sub-mixing chamber 122; there may also be more than three water retaining members 400, and the embodiment of the present application does not impose excessive restrictions on the number of water retaining members 400.

[0082] Reference Figure 1 , Figure 3 and Figure 4 As shown, in a possible implementation, the air outlet channel 500 has a gas inlet 510 and a gas outlet 520 .

[0083] The gas inlet 510 is located in the air outlet cavity 121 and communicates with the air outlet cavity 121 .

[0084] The gas outlet 520 is located outside the box body 100 .

[0085] In this way, the air outlet channel 500 can be connected to the dust collection component in the cleaning device through the gas outlet 520, and the air flow in the air outlet cavity 121 enters the air outlet channel 500 through the gas inlet 510, and then enters the dust collection component through the gas outlet 520.

[0086] Continue to refer to Figure 1 , Figure 3 and Figure 4 As shown, the gas inlet 510 can face away from the water retaining member 400. When the box body 100 is laid flat, even if sewage surges and splashes, causing a small amount of sewage to be sprayed into the air outlet cavity 121, the outer wall of the air outlet channel 500 close to the gas inlet 510 can prevent the sewage from flowing directly into the air outlet channel 500.

[0087] Further, the sum of the cross-sectional areas of the communication openings 410 on the two water retaining members 400 is greater than or equal to the cross-sectional area of ​​the gas inlet 510 .

[0088] In this way, it is ensured that the flow rate of the airflow entering the air outlet cavity 121 through the connecting openings 410 on the two water retaining members 400 will not be restricted, thereby preventing the air pressure in the air outlet cavity 121 from being too high.

[0089] It is understandable that the cross-sectional areas of the connecting openings 410 on the two water retaining members 400 can be equal, or one larger and one smaller, as long as the sum of the cross-sectional areas of the two is greater than or equal to the cross-sectional area of ​​the gas inlet 510 .

[0090] Reference Figure 3 and Figure 4 As shown, in a possible implementation, the water guide member 300 includes a water guide body 310 and a support portion 320 disposed on the water guide body 310 , the water guide body 310 is located between the cover body 200 and the support portion 320 , and the water blocking member 400 is located on the water guide body 310 .

[0091] The support portion 320 abuts against the inner wall of the box body 100 to separate the box body 100 into a sewage chamber 110 and a mixing chamber 120 .

[0092] In this way, the water guide body 310 can correspond to the sewage channel 130. When sewage is sprayed out from the sewage channel 130, it can be blocked by the water guide body 310 to prevent the sewage from being directly sprayed on the inner wall of the box body 100, causing dirt and water stains to stick to the inner wall of the box body 100 and be difficult to clean.

[0093] Specifically, refer to Figure 1 and Figure 3 As shown, since the sewage channel 130 is connected to the sub-mixing chamber 122 , after the sewage is sprayed onto the water guide body 310 , it will flow into the sewage chamber 110 along the water guide body 310 in the sub-mixing chamber 122 .

[0094] Exemplarily, the water-guiding body 310 may be an arc-shaped plate structure, a cylindrical structure, a conical structure, or other shapes, as long as the water-guiding body 310 can prevent sewage from being sprayed directly onto the inner wall of the box 100 . The embodiments of the present application do not impose too many restrictions on this.

[0095] Reference Figure 2 , Figure 3 and Figure 4 As shown, in a specific implementation, the water retaining member 400 includes a first water retaining portion 420 and a second water retaining portion 430 which are sequentially arranged, the first water retaining portion 420 is connected to the cover body 200 , and the first water retaining portion 420 abuts against the inner wall of the box body 100 .

[0096] The second water blocking portion 430 is connected to the supporting portion 320 .

[0097] In this way, the first water retaining portion 420 can be sealed against the inner wall of the box body 100, and there is a gap between the second water retaining portion 430 and the inner wall of the box body 100. The first water retaining portion 420, the second water retaining portion 430, the support portion 320 and the inner wall of the box body 100 are surrounded by a connecting port 410. The first water retaining portion 420 is close to the air outlet channel 500, and the sewage surge is suppressed by the first water retaining portion 420 to prevent the sewage from directly splashing into the air outlet channel 500. The second water retaining portion 430 blocks part of the sewage from flowing into the air outlet cavity 121 along the water guide body portion 310.

[0098] For example, refer to Figure 2 , Figure 3 and Figure 4 As shown, the length of the first water retaining portion 420 may be greater than the length of the second water retaining portion 430 , so that the communication port 410 is away from the air outlet channel 500 provided on the cover body 200 .

[0099] Of course, the first water retaining portion 420 and the second water retaining portion 430 may be an integrally formed part to facilitate processing and enhance the connection strength between the two.

[0100] Reference Figure 3 , Figure 4 and Figure 6 As shown, in a possible implementation, the sewage tank provided by the present application has a support pipe 140 in the tank body 100 , the inner wall of the support pipe 140 forms a sewage channel 130 , and the support portion 320 is inserted into the support pipe 140 .

[0101] In this way, the support part 320 is inserted into the support pipe 140 to improve the stability of the support part 320 in the box body 100. One end of the support part 320 is disposed in the sewage chamber 110, and the other end extends into the sub-mixing chamber 122 through the support part 320, so that the sewage sprayed from the sewage channel 130 enters the sub-mixing chamber 122, and then flows into the sewage chamber 110 along the water guide body 310.

[0102] For example, refer to Figure 2 As shown, the support portion 320 is provided with a mounting through hole 321 , and the support portion 320 is inserted into the support tube 140 through the mounting through hole 321 , so that one end of the support tube 140 extends into the sub-mixing chamber 122 through the mounting through hole 321 .

[0103] Reference Figure 2 As shown, in a possible implementation, a first filter portion 330 is disposed on the support portion 320 , the first filter portion 330 corresponds to the sub-mixing chamber 122 , and the first filter portion 330 is used to filter impurities in the sewage entering the sewage chamber 110 .

[0104] In this way, when the sewage flows in the sub-mixing chamber 122 along the water guiding main body 310 to the sewage chamber 110, the solid impurities entrained in the sewage fall on the first filter part 330, and the sewage enters the sewage chamber 110 to separate the solid impurities entrained in the sewage, so as to facilitate the subsequent treatment of the sewage and solid impurities in the sewage tank.

[0105] For example, refer to Figure 2 As shown, the first filter portion 330 may be a filter screen.

[0112] It is understandable that at least one seal 600, illustratively, can be one seal 600, which is disposed between the cover 200 and the box body 100, or the seal 600 is disposed between the box body 100 and the support portion 320; there can also be two seals 600, with seals 600 being disposed between the cover 200 and the box body 100, and between the box body 100 and the support portion 320; of course, there can also be more than two seals 600, and the embodiments of the present application do not impose too many restrictions on this.

[0113] Exemplarily, the sealing member 600 may be a sealing ring.

[0114] Reference Figure 2 As shown, in a possible implementation, the sewage tank provided in the present application further includes a detection member 700 , which is disposed between the cover body 200 and the support portion 320 , and is used to detect the water level in the tank body 100 .

[0115] In this way, when the water level in the box 100 reaches a preset value, the detection element 700 sends a signal to remind the user to clean the sewage and solid garbage in the box 100.

[0116] Exemplarily, the detection member 700 may be a water level monitor commonly used in the prior art, and the embodiments of the present application do not impose too many limitations on this.

[0117] On the other hand, the present application provides a cleaning device, including a device host and a sewage tank as described above, wherein the sewage tank is connected to the device host.

[0118] In this way, when the sewage tank of the equipment host is laid flat at 180 degrees, the water retaining member 400 can suppress the sewage surge to prevent the sewage from directly splashing into the air outlet channel 500 connected to the air outlet cavity 121 and then entering the equipment host.

[0119] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or replace some or all of the technical features therein with equivalents.
