Description

TECHNICAL FIELD

[0001] The present disclosure relates to the technical field of cleaning equipment, and in particular, to a cleaning equipment. BACKGROUND

[0002] With the development of household cleaning equipment and the increasing demand of household users for cleaning effect, the scrubber is favored by consumers due to its high efficiency, convenience, environmental protection, and dry-wet dual use characteristics. The dry-wet dual use cleaning equipment is equipped with a sewage tank. When in use, the external dirt is sucked into the sewage tank through negative pressure.

[0003] Based on the principle of using negative pressure to suck sewage, a large amount of gas is inevitably mixed in the dirt entering the sewage tank. Further, due to the design trend of gradually miniaturizing and lightening the cleaning equipment, the volume of the sewage tank is also gradually reduced, which leads to the accelerated flow rate of the gas-liquid mixture in the sewage tank cavity, and the liquid is easily sucked into the negative pressure motor along with the airflow, which can cause unnecessary damage to the motor and affect the service life of the cleaning equipment.

[0004] In addition, due to the continuous expansion of the use scenarios of the scrubber, the scrubber can be laid flat to clean low areas such as the bottom of the bed and the bottom of the sofa, which requires the sewage tank of the scrubber to have the ability to separate water and gas in a flat state. Currently, the flat sewage tank on the market generally has the drawback of being unable to be used under high power and large water volume. The water in the sewage tank is easily sucked into the motor, especially when entering a lower area, which leads to the gradual flattening of the sewage tank, further increasing the air flow rate in the sewage cavity, and increasing the probability of water vapor being sucked into the motor. UTILITY MODEL CONTENT

[0005] The present disclosure provides a cleaning equipment to solve the problems in the prior art.

[0006] According to a first aspect of the present disclosure, a cleaning equipment is provided, with the side of the cleaning equipment facing the user being referred to as the rear side, and the side away from the user being referred to as the front side. The cleaning equipment comprises:

[0007] a machine body;

[0008] a sewage tank, the top of the sewage tank being provided with a tank cover; wherein a liquid inlet and a gas outlet are provided on the tank cover;

[0009] a main partition plate, the main partition plate being arranged in the sewage tank and being configured to separate the top region of the sewage tank into a first region located on the front side and a second region located on the rear side;

[0010] A partition plate is located in the first area and is configured to extend forward from the main partition plate to abut against the inner wall surface of the sewage bucket to divide the first area into a first space and a second space; wherein the liquid inlet is located in the first space and the gas outlet is located in the second space;

[0011] The partition plate is configured to extend downward from the bottom surface of the bucket cover and extend at least partially in a manner inclined away from the second space.

[0012] One beneficial effect of the present disclosure is that the gas-liquid mixture flowing into the first space through the liquid inlet can achieve gas-liquid separation according to the gravity and inertial difference of the gas and the liquid, wherein the liquid cannot pass over the partition plate and can be thrown downward into the water storage area at the bottom of the sewage bucket; while the gas can pass over the partition plate into the second space, and the gas changes the flow direction in the process of passing through the partition plate, thereby entering the second space and being discharged from the gas outlet on the bucket cover. The present disclosure improves the water vapor separation effect in the sewage bucket, avoids the liquid entering the negative pressure motor with the gas flow, thereby preventing the motor from being damaged, and improves the service life of the cleaning equipment.

[0013] Specifically, the partition plate is configured to extend in a manner inclined away from the second space from the bottom surface of the bucket cover, thereby dividing the first area into a first space with a smaller volume and a second space with a larger volume. In the flow direction, the cross-sectional area of the first space gradually decreases, thereby increasing the flow rate of the fluid in the first space and increasing the inertial force of the fluid. When the fluid flows through the bottom end of the partition plate, the gas-liquid mixture suddenly slows down due to the sudden increase in the flow passage area, thereby avoiding the gas driving the liquid to turn into the second space. In addition, since the liquid tends to flow along the wall, part of the liquid flows along the extension direction of the partition plate. The inclined extension of the partition plate can guide the liquid to a position away from the second space, thereby avoiding the liquid from entering the second space.

[0014] Further, when the cleaning equipment is lying down for cleaning, the water storage area at the bottom of the sewage bucket can be in communication with the second area located at the rear side of the cleaning equipment, and the liquid cannot flow back into the first area, thereby not affecting the first area to continue gas-liquid separation. It can be seen that even in the lying state, the cleaning equipment can still work normally, and the liquid in the sewage bucket cannot enter the second space, thereby avoiding the liquid from entering the negative pressure motor, thereby preventing the motor from being damaged and improving the service life of the cleaning equipment.

[0015] Other features and advantages of the present disclosure will become apparent from the following detailed description of exemplary embodiments thereof, taken in conjunction with the accompanying drawings. BRIEF DESCRIPTION OF DRAWINGS

[0038] The present disclosure provides a cleaning device. For ease of description, the present disclosure is described from the perspective of a user in the following description, with the side of the cleaning device facing the user being referred to as the rear side, and the side of the cleaning device facing away from the user being referred to as the front side. Referring to Figure 2 the direction of the view, from another perspective, the direction shown on the right side of Figure 2 the figure can be referred to as the front side, Figure 2 the direction shown on the left side of the figure can be referred to as the rear side.

[0039] The cleaning device of the present disclosure can be a handheld cleaning device such as a handheld washing machine, a handheld wet vacuum cleaner, a handheld floor washing machine, a handheld fabric washing machine, and the like, which are well known to those skilled in the art, or a self-moving cleaning device such as a floor cleaning robot, a sweeping and mopping integrated robot, and the like, which are well known to those skilled in the art. The cleaning device at least includes a machine body and a sewage tank, and can further include a floor brush assembly, a cleaning liquid tank, and the like, wherein the machine body serves as a carrier for mounting various functional elements required by the cleaning device.

[0040] The floor brush assembly of the cleaning device is arranged at the bottom end of the machine body and is used to clean the working surface such as the floor, the carpet, or the surface of furniture; a rotating shaft can be arranged between the floor brush assembly and the machine body, and the floor brush assembly can rotate relative to the machine body through the rotating shaft, thereby facilitating the user to clean the working surface by dragging the cleaning device back and forth. When cleaning the working surface, the floor brush assembly is always attached to the working surface, thereby wiping the stains on the working surface.

[0041] The sewage tank of the cleaning device is used to contain the dirt sucked from the working surface, which can be sewage generated during cleaning or various garbage sucked from the working surface. A negative pressure motor can be arranged in the cleaning device, which can form a negative pressure environment in the sewage tank, thereby sucking the dirt into the sewage tank by negative pressure. It should be noted that the complete cleaning device is not shown in the drawings of the present disclosure, and only the sewage tank of the cleaning device is shown for simplicity.

[0042] Reference Figure 1 and Figure 2 The top of the sewage tank is provided with a tank cover 2, which can be mounted on the top of the through shell 1. The tank shell 1 is the main structure of the sewage tank, and the inside thereof is provided with a cavity for storing liquid. Further, the tank cover 2 includes a main body member 20 and a cover member 23 mounted together, wherein the cover member 23 is a structure that is buckled above the tank shell 1, and the main body member 20 is configured to extend into the cavity inside the tank shell 1, which can at least play a role of separating space.

[0043] Reference Figure 3 , Figure 6 and Figure 9The liquid inlet 21 and the gas outlet 22 are arranged on the bucket cover 2. The liquid inlet 21 is arranged on the main body member 20, through which the liquid can flow into the inner cavity of the sewage bucket. In one specific embodiment of the present disclosure, a connecting pipe 12 is arranged inside the bucket shell 1, and an adapter pipe 24 is arranged on the main body member 20. The bottom end of the connecting pipe 12 is connected to the suction port of the cleaning device, so that the external dirt can be sucked into the connecting pipe 12 and flow upward along the connecting pipe 12 under the action of negative pressure. The top end of the connecting pipe 12 is connected to the adapter pipe 24, and the other end of the adapter pipe 24 is connected to the liquid inlet 21, so that the dirt from the connecting pipe 12 flows to the liquid inlet 21 through the adapter pipe 24, and then flows into the inner cavity of the sewage bucket through the liquid inlet 21.

[0044] The gas outlet 22 is arranged on the main body member 20, which is at least used to form a gas path connection with the negative pressure motor. The negative pressure motor can suck the inner cavity of the sewage bucket into a negative pressure environment through the gas outlet 22. When the negative pressure motor is working, the external air can be sucked into the connecting pipe 12 together with the dirt, and then enter the inner cavity of the sewage bucket through the adapter pipe 24 and the liquid inlet 21. The gas-liquid mixture needs to be separated in the sewage bucket, and the gas can be sucked into the negative pressure motor through the gas outlet 22.

[0045] In one specific embodiment of the present disclosure, a filter assembly 231 is arranged on the top of the cover member 23, and the filter assembly 231 is arranged on the gas flow path from the gas outlet 22 to the negative pressure motor. The gas sucked out of the gas outlet 22 needs to pass through the filter assembly 231 for filtration before flowing to the negative pressure motor. It can be understood that the gas entering the sewage bucket together with the dirt is easy to carry dust, which will pollute and burden the negative pressure motor. The filter assembly 231 can preferably adopt a Hepa filter element, thereby improving the filtering effect.

[0046] A main partition plate 3 is arranged in the sewage bucket, and specifically, the main partition plate 3 can be a part of the main body member 20. Referring to Figure 2 , the main partition plate 3 is configured to divide the top region of the sewage bucket into a first region 31 located on the front side and a second region 32 located on the rear side. In one embodiment of the present disclosure, referring to Figure 4 、 Figure 6 and Figure 7 , a solid-liquid separation frame 6 is arranged in the sewage bucket at the position below the main partition plate 3. It can be understood that the dirt entering the sewage bucket contains not only liquid such as sewage, but also solid waste such as hair, paper, and debris. During the subsequent discharge process, the solid waste is easy to cause blockage. Therefore, the present disclosure is provided with the solid-liquid separation frame 6 in the sewage bucket. The solid-liquid mixture can be filtered when passing through the solid-liquid separation frame 6, the solid waste can be filtered out and left above the solid-liquid separation frame 6, and the liquid can leak into the water storage area below the solid-liquid separation frame 6.

[0047] In the non-laying state of the cleaning device, such as the upright or inclined state, the liquid can stay in the water storage area at the bottom of the sewage tank under the action of gravity and will not overflow beyond the height of the solid-liquid separation frame 6. However, when the cleaning device is used to clean low areas such as the bottom of a bed or a sofa, the user will lay the machine body flat, and the sewage tank will also be laid flat, at this time, the front side is located above, and the rear side is located below, that is, the first area 31 formed by the main partition plate 3 is located above, and the second area 32 is located below. At this time, the liquid originally in the water storage area at the bottom of the sewage tank can pass through the corresponding solid-liquid separation frame 6 of the second area 32 and overflow into the second area 32. As for the first area 31, whether in the laying state or the non-laying state, the liquid stored in the sewage tank will not flow back into the first area 31.

[0048] Reference Figure 3 And Figure 8 The sewage tank is provided with a partition plate 4, specifically, the partition plate 4 can be part of the main body member 20. The partition plate 4 is located in the first area 31 and is configured to extend forward from the main partition plate 3 to abut against the inner wall surface of the sewage tank to separate the first area 31 into a first space 41 and a second space 42; wherein the liquid inlet 21 is located in the first space 41, and the gas outlet 22 is located in the second space 42. As described above, the liquid stored in the sewage tank will not flow back into the first area 31, and the liquid inlet 21 and the gas outlet 22 are both located in the first area 31, thereby enabling the liquid from the liquid inlet 21 to flow unidirectionally to other areas, and during the cleaning process, the liquid will not flow into the gas outlet 22, whether in the laying state or the non-laying state.

[0049] The gas-liquid mixture flowing into the first space 41 from the liquid inlet 21 can realize gas-liquid separation according to the gravity and inertia difference of the gas and the liquid, wherein the liquid cannot pass over the partition plate 4, and the liquid can be thrown downward into the water storage area at the bottom of the sewage tank; the bottom edge of the partition plate 4 is located above the bottom edge of the main partition plate 3 and is spaced apart from the solid-liquid separation frame 6 to form a channel transversely connecting the first space 41 and the second space 42, so that the gas can enter the second space 42 through the space between the bottom edge of the partition plate 4 and the solid-liquid separation frame 6. The gas changes the flow direction during the process of passing through the partition plate 4, thereby entering the second space 42 and being discharged from the gas outlet 22 on the tank cover 2. The present disclosure improves the water vapor separation effect in the sewage tank, avoids the liquid entering the negative pressure motor with the gas flow, thereby preventing the motor from being damaged, and improves the service life of the cleaning device.

[0050] Further, the partition plate 4 is configured to extend downward from the bottom surface of the bucket cover 2 and extend at least partially in a manner inclined away from the second space 42. In one embodiment of the present disclosure, the partition plate 4 can be configured to extend entirely in an inclined manner; in another embodiment of the present disclosure, referring to Figure 3 and Figure 8 , the partition plate 4 comprises a first extension section 401 connected with the bottom surface of the bucket cover 2 and extending along the axis direction of the sewage bucket, and a second extension section 402 extending from the end of the first extension section 401 in a manner inclined away from the second space 42. The present disclosure preferably adopts the partition plate 4 provided in the second embodiment, and specifically, the first extension section 401 extends along the axis direction, thereby achieving avoidance of the liquid outlet 21, so that the liquid flowing out of the liquid outlet 21 does not directly impact the first extension section 401 of the partition plate 4, thereby improving the drainage efficiency of the liquid outlet 21.

[0051] The partition plate 4 is configured to extend in a manner inclined away from the second space 42 from the bottom surface of the bucket cover, thereby dividing the first area 31 into the first space 41 with a smaller volume and the second space 42 with a larger volume. Referring to Figure 5 , the cross-sectional area of the first space 41 at the end of the second extension section 402 is denoted as S1, and the cross-sectional area of the second space 42 at the end of the second extension section 402 is denoted as S2; wherein S1, S2 satisfy the following relationship: S1+S2≤3000mm 2 , and S2 / S1≥1.3. Since S1+S2≤3000mm 2 , it can be seen that the sewage bucket of the present disclosure is a small-volume sewage bucket, thereby causing the flow rate of the gas-liquid mixture in the sewage bucket to increase, and the liquid is easily carried by the gas flow.

[0052] Based on this, in order to improve the gas-liquid separation effect in the first area 31, the partition plate 4 is inclined in the present disclosure. In the flow direction, the cross-sectional area of the first space 41 gradually decreases, thereby increasing the flow rate of the fluid in the first space 41 and increasing the inertial force of the fluid. When the fluid flows through the bottom end of the partition plate 4, the flow area suddenly increases, causing the gas-liquid mixture to suddenly decelerate, thereby avoiding the gas driving the liquid to turn into the second space 42. In addition, since the liquid easily flows along the wall, there is part of the liquid flowing along the extension direction of the partition plate 4, and the inclined extension of the partition plate can guide the liquid to a position away from the second space 42, thereby avoiding the liquid entering the second space 42.

[0053] Further, when the cleaning device is laid down for cleaning, the water storage area at the bottom of the sewage tank can communicate with the second area 32 located at the rear side of the cleaning device, and liquid cannot flow back into the first area 31, so that the first area 31 can continue to perform gas-liquid separation. It can be seen that even in the laid-down state, the cleaning device can still work normally, and the liquid in the sewage tank cannot enter the second space 42, thereby avoiding the liquid entering the negative pressure motor, preventing the motor from being damaged, and prolonging the service life of the cleaning device.

[0054] In one embodiment of the present disclosure, referring to Figure 3 and Figure 8 A guide plate 5 is arranged in the first space 41 adjacent to the liquid inlet 21, and the guide plate 5 is configured to form a guide channel in communication with the liquid inlet 21 together with the main partition plate 3, the partition plate 4, and the inner wall of the sewage tank. The guide plate 5 is provided with a guide opening 51 at a position away from the partition plate 4. The guide plate 5 is arranged adjacent to the liquid inlet 21, so that the liquid flowing out of the liquid inlet 21 can first flow to the surface of the guide plate 5 and flow along the surface of the guide plate 5. The liquid can further flow downward through the guide opening 51. Since the guide opening 51 is arranged on the guide plate 5 away from the partition plate 4, the guide plate 5 can guide the liquid to a position away from the partition plate 4, thereby reducing the liquid flowing along the surface of the partition plate 4.

[0055] Further, in a specific embodiment of the present disclosure, the orthographic projection of the guide opening 51 in the axial direction of the sewage tank is configured not to overlap the partition plate 4. In the upright state of the cleaning device, the liquid passing through the guide opening 51 can fall vertically under the action of gravity. Since the orthographic projection of the guide opening 51 and the partition plate 4 in the vertical direction does not overlap, the liquid falling from the guide opening 51 will not impact on the partition plate 4, but will be located away from the partition plate 4. The present disclosure can guide the liquid to a position further away from the partition plate 4 by arranging the guide plate 5 with the guide opening 51, thereby further avoiding the liquid from entering the second space 42 over the partition plate 4, and preventing the air outlet 22 from being waterlogged.

[0056] In one embodiment of the present disclosure, referring to Figure 4 and Figure 9 A blocking strip 11 is arranged on the front side wall of the sewage tank, and the blocking strip 11 is configured to extend at least from the position of the end of the second extension section 402 to the bottom of the sewage tank. The liquid in the sewage tank has a wall adhesion effect. For the liquid adsorbed on the wall of the tank, the blocking strip 11 can play a role of converging and guiding the liquid, and the liquid can be further guided downward from the end position of the second extension section 402 of the partition plate 4.

[0057] In addition, since the sewage bucket of the present disclosure has a small volume, the front-to-rear distance of the bucket body is compressed, thereby increasing the flow rate of the airflow inside the bucket body, so that the liquid droplets attached to the inner wall surface of the bucket shell 1 are entrained by the airflow. Without the blocking strip 11, the liquid is easy to move to the inner wall surface of the bucket shell 1 corresponding to the second space 42 along with the airflow, and thus may be sucked into the negative pressure motor through the air outlet 22. The present disclosure can block the movement of liquid droplets on the inner wall surface of the bucket shell 1 by arranging the blocking strip 11 at a position corresponding to the interval region between the partition plate 4 and the solid-liquid separation frame 6 of the bucket body, thereby avoiding the movement of liquid to the second space 42.

[0058] In one specific embodiment of the present disclosure, the blocking strip 11 extends upward to the junction of the first extension section 401 and the second extension section 402. In this way, the liquid can be guided by the blocking strip 11 from the bottom position of the first extension section 401 of the partition plate 4. Specifically, the first extension section 401 and the blocking strip 11 both extend along the axial direction of the sewage bucket, so that the liquid always has a corresponding guide structure during downward flow, thereby improving the guide effect.

[0059] In one specific embodiment of the present disclosure, the blocking strip 11 is configured to extend downward to the solid-liquid separation frame 6. In this way, the liquid can flow along the blocking strip 11 from the partition plate 4 all the way down to the solid-liquid separation frame 6 for solid-liquid separation, and then smoothly flow to the bottom of the sewage bucket.

[0060] In one embodiment of the present disclosure, a blocking rib extending circumferentially along the sewage bucket is arranged on the front side wall surface of the second space 42. Without the blocking rib, a small amount of liquid droplets adsorbed on the inner wall surface of the bucket shell 1 corresponding to the second space 42 may move in the direction of the air outlet 22 along with the airflow, and thus may be sucked into the negative pressure motor. The present disclosure can block the movement of liquid droplets on the inner wall surface of the bucket shell 1 of the second space 42 by arranging a blocking rib extending circumferentially along the sewage bucket on the front side wall surface of the second space 42, thereby avoiding the liquid from being sucked into the negative pressure motor.

[0061] In one embodiment of the present disclosure, with reference to Figures 2 to 4The vent 22 is located at the top of the second space 42 and is configured to open towards the front wall of the sewage tank. The vent is also configured to have a predetermined distance from the main partition 3. In the prior art, the vent 22 is usually located on the bottom surface of the tank cover 2, and the opening of the vent 22 usually faces the bottom surface of the sewage tank. When the user pushes and pulls the cleaning device back and forth to clean the working surface, the liquid in the sewage tank will splash up, and the downward-facing vent 22 can easily suck in the liquid. In addition, when the sewage tank is lying flat, once water enters the second space 42, the liquid can easily overflow into the vent 22. In this disclosure, the opening of the vent 22 is positioned facing the front wall of the sewage tank, so that when the user pushes and pulls the cleaning equipment back and forth and the liquid in the sewage tank splashes, the liquid is less likely to enter the vent 22. In the scenario where the sewage tank is lying flat, the opening of the vent 22 is away from the water surface. Since there is a predetermined distance between it and the main partition 3, the distance between the vent 22 and the water surface is greater than the predetermined distance. In this embodiment, even if a small amount of water enters the second space 42, the liquid is still less likely to enter the vent 22.

[0062] In one embodiment of this disclosure, reference is made to Figure 10 A baffle 7 is installed in the second space 42. The baffle 7 is constructed to extend at an angle from the bottom of the main partition 3 toward the vent 22. When the sewage tank is lying flat, the top of the baffle 7 is constructed to be higher than the bottom of the vent 22 and is located adjacent to the bottom of the vent 22. In the scenario where the sewage tank is lying flat, the liquid concentrates at the bottom of the sewage tank (see reference). Figure 10 In the viewing direction, during the process of the user reciprocatingly pushing and pulling the cleaning device to clean the work surface, the liquid stored on the lower left side of the wastewater tank is prone to rushing upwards and to the right under the action of inertia, thus posing a risk of entering the second space 42. The baffle 7 can block the liquid that rushes up due to inertia. Specifically, the baffle 7 divides the second space 42 into two areas, the upper area for gas and the lower area for liquid. During normal cleaning, the liquid cannot cross the baffle 7, thus achieving gas-liquid separation. Even when the wastewater tank is lying flat, the liquid will not enter the air outlet 22.

[0063] In one embodiment of the present disclosure, the solid-liquid separation frame 6 is configured to move along the axial direction of the sewage tank to a first position adjacent to the main partition plate 3 and a second position away from the main partition plate 3; when the sewage tank is in the flat state, the solid-liquid separation frame 6 is configured to be located at the second position. Further, an electromagnetic device can be provided on the machine body, and a magnet is provided on the solid-liquid separation frame 6, and the electromagnetic device is configured to attract the magnet to drive the solid-liquid separation frame 6 to move when energized. In this embodiment, the electromagnetic device is selected to drive the solid-liquid separation frame 6 to move between the first position and the second position. It should be noted that other technical means commonly used by those skilled in the art can also be used to drive the solid-liquid separation frame 6, such as through a motor, mechanical transmission, etc., and the present disclosure does not limit this.

[0064] When the sewage tank is in the flat state, the electromagnetic device is started to attract the magnet on the solid-liquid separation frame 6, thereby driving the solid-liquid separation frame 6 to move to the second position away from the main partition plate 3; when the sewage tank is in a non-flat state, for example, in an upright state, the electromagnetic device is turned off to cancel the magnetic force, and the solid-liquid separation frame 6 returns to the first position adjacent to the main partition plate 3. It can be understood that when the solid-liquid separation frame 6 is located at the second position, it is far away from the liquid outlet 21, and if the sewage tank is upright at this time and the solid-liquid separation frame 6 does not move back to the first position, the liquid will cause a large impact on the solid-liquid separation frame 6, and the water splashes upward and is easily wrapped by the airflow, thereby being sucked into the air outlet 22. Therefore, in the upright state, the solid-liquid separation frame 6 needs to move towards the bucket cover 2 to shorten the distance between the solid-liquid separation frame 6 and the liquid outlet 21, thereby reducing the splashing of the water flow and effectively avoiding the risk of excessive water vapor entering the motor.

[0065] In one embodiment of the present disclosure, referring to Figure 11 and Figure 12 , the part of the main partition plate 3 located in the second space 42 is provided with a through opening 33 penetrating to the second area 32, and a pivotable sealing plate 8 is provided at the position of the through opening 33. The sealing plate 8 can be rotatably connected to the main partition plate 3, and a counterweight 81 can be provided on the other side of the hinge point to drive the sealing plate 8 to rotate by using its gravity. As shown in Figure 11 , when the machine body is in the flat state, the sealing plate 8 is configured to rotate to seal the through opening 33; as shown in Figure 12 , when the machine body is in a non-flat state, the sealing plate 8 is configured to rotate to open the through opening 33 to connect the second space 42 and the second area 32.

[0066] Specifically, when the fuselage is in the flat state, the sealing plate 8 can seal the through hole 33, so that the main partition plate 3 can completely isolate the first area 31 and the second area 32, and the liquid can stay in the second area 32 without entering the first area 31 through the through hole 33. In this way, the liquid is prevented from entering the second space, and the risk of excessive water vapor entering the motor is avoided.

[0067] When the fuselage is in a non-flat state, for example, in an upright state, the liquid is stored in the bottom area of the sewage bucket, and there is no liquid in the second area 32, so the through hole 33 can be opened, and the second space 42 is connected with the second area 32. At this time, the space for gas-liquid separation is expanded to twice (i.e., the first area 31 + the second area 32), and is no longer limited to the first area 31. The expansion of the gas-liquid separation space can reduce the flow rate of the gas, thereby improving the effect of gas-liquid separation, and avoiding the risk of high-speed airflow carrying water vapor into the motor.

[0068] In one specific embodiment of the present disclosure, the through hole 33 is configured to be located on the main partition plate 3 at a position corresponding to the air outlet 22; in the flat state, the through hole 33 is located below the air outlet 22, and the vertical projection of the air outlet 22 covers the through hole 33. Since the sealing plate 8 in this embodiment opens or closes the through hole 33 by gravity, in the partial inclined state, the liquid has flowed into the second area 32, but the sealing plate 8 has not completely sealed the through hole 33. The through hole 33 is arranged at a position corresponding to the air outlet 22, i.e., as high as possible, so as to avoid the liquid entering the second space 42 through the through hole 33 as much as possible. Even if a small amount of liquid enters the second space 42, since the vertical projection of the air outlet 22 covers the through hole 33, and in the flat state, the opening of the air outlet 22 faces away from the water surface, the small amount of liquid entering the second space 42 will not cause the air outlet 22 to be waterlogged.

[0069] In another specific embodiment of the present disclosure, the through hole 33 is located on the main partition plate 3 adjacent to the solid-liquid separation frame 6. In this way, the through hole 33 is located on the main partition plate 3 away from the air outlet 22, so that even if a small amount of liquid enters the second space 42 from the through hole 33, due to the far distance between the liquid and the air outlet 22, the liquid can flow back into the water storage space, and the air outlet 22 is not easily waterlogged.

[0070] Application scenarios

[0071] In the household cleaning scenario, the cleaning device is a handheld scrubber, and the user drags the handheld scrubber back and forth to achieve the purpose of cleaning the working surface. The sewage tank of the handheld scrubber is used to contain the dirt sucked from the working surface, which can be sucked into the connecting pipe 12 and flow upward along the connecting pipe 12 to the adapter pipe 24 under the action of negative pressure, and then flow to the liquid inlet 21 for flowing into the inner cavity of the sewage tank through the liquid inlet 21.

[0072] The gas-liquid mixture flowing into the first space 41 from the liquid inlet 21 can realize gas-liquid separation according to the gravity and inertia difference of the gas and the liquid, wherein the liquid cannot pass over the partition plate 4 and can be thrown downward into the water storage area at the bottom of the sewage tank; and the gas can pass over the partition plate 4 into the second space 42, and the gas changes the flow direction during passing through the partition plate 4, thereby entering the second space 42 and being discharged from the gas outlet 22 on the tank cover 2. The present disclosure improves the water vapor separation effect in the sewage tank, avoids the liquid entering the negative pressure motor with the gas flow, thereby preventing the motor from being damaged, and improves the service life of the handheld scrubber.

[0073] Further, the partition plate 4 is configured to be inclined and extended away from the second space 42 from the bottom surface of the tank cover 2. In the flow direction, the cross-sectional area of the first space 41 gradually decreases, thereby increasing the flow velocity of the fluid in the first space 41 and increasing the inertia force of the fluid. When the fluid flows through the bottom end of the partition plate 4, the gas-liquid mixture suddenly slows down due to the sudden increase in the flow area, thereby avoiding the gas driving the liquid to turn into the second space 42. In addition, since the liquid easily flows along the wall, there is part of the liquid flowing along the extension direction of the partition plate 4, and the inclined extension of the partition plate can guide the liquid to a position away from the second space 42, thereby avoiding the liquid entering the second space 42.

[0074] When it is necessary to clean low areas such as the bottom of the bed and the bottom of the sofa, the user will lay down the handheld scrubber, and the sewage tank will also be laid down. At this time, the water storage area at the bottom of the sewage tank can be in communication with the second area 32 at the rear side, and the liquid will not flow backward into the first area 31, thereby not affecting the first area 31 to continue gas-liquid separation. It can be seen that even in the laid-down state, the handheld scrubber can still work normally, and the liquid in the sewage tank will not enter the second space 42, thereby avoiding the liquid entering the negative pressure motor, thereby preventing the motor from being damaged, and improving the service life of the handheld scrubber.

[0075] Having described above several embodiments of the disclosure, any modifications and variations that fall within the scope of the described embodiments are also contemplated by the inventor(s). As such, the foregoing description is not intended to limit the scope of the disclosure, and it is recognized that modifications are contemplated which can provide one or more benefits and which are within the scope of the disclosure. The disclosure is defined by the appended claims.
