Description

Technical Field

[0001] The present disclosure relates to the field of cleaning equipment, and more specifically, to a cleaning equipment. Background Art

[0002] Environmental sanitation is a crucial factor affecting the quality of life. Consequently, as people's expectations for quality of life continue to rise, so too do their demands for environmental sanitation. Consequently, a wide range of floor cleaning equipment has emerged, including vacuum cleaners, sweepers, and floor scrubbers. A floor scrubber is a cleaning machine that cleans the floor while simultaneously sucking up wastewater and removing it from the site.

[0003] Existing floor scrubbers usually use a fan unit to create negative pressure in the inner cavity of the sewage bucket, thereby sucking the sewage on the working surface into the sewage bucket. However, during the operation of the fan unit, some water vapor in the sewage will enter the fan unit along with the air flow. The fan unit is prone to malfunction after water enters, thereby affecting the normal operation of the cleaning equipment and further affecting the user experience. In existing cleaning scenarios, floor scrubbers need to lie flat to work in order to enter low areas for cleaning. However, in this scenario, the sewage surface in the sewage bucket is too close to the air outlet of the sewage bucket, especially when the floor scrubber is in a lying state and the user pushes and pulls back and forth, causing the sewage in the sewage bucket to sway back and forth and splashing liquid, which easily causes water vapor to enter the fan unit through the air outlet of the sewage bucket. Utility Model Content

[0004] In order to solve the problem that water vapor easily enters the fan unit when the cleaning device is lying flat for operation, the present disclosure provides a cleaning device.

[0005] According to a first aspect of the present disclosure, a cleaning device is provided, comprising a sewage bucket, the sewage bucket comprising a bucket lid and a bucket body that snap together to form an inner cavity, and a sewage inlet pipe located in the inner cavity; the inner cavity comprising a first chamber and a second chamber communicating with the first chamber, wherein the sewage inlet pipe is at least partially located in the first chamber, the first chamber being configured to accommodate sewage entering through the sewage inlet pipe, and the second chamber being located downstream of the first chamber, such that airflow entering the sewage bucket through the sewage inlet pipe exits the sewage bucket through an air outlet of the second chamber;

[0006] The second chamber includes a bottom wall protruding outward from the side wall of the barrel body; the barrel cover is provided with a first partition and a second partition extending in the vertical direction of the sewage barrel, and the outlet of the sewage inlet pipe is located between the first partition and the second partition; wherein, the second partition is arranged at a position where the first chamber and the second chamber are connected, and an air inlet connecting the first chamber and the second chamber is formed between the second partition and the bottom wall, and the height of the air inlet is lower than the height of the outlet of the sewage inlet pipe.

[0007] Since the sewage inlet pipe is at least partially located in the first chamber, the first chamber is used to accommodate sewage entering through the sewage inlet pipe, that is, the first chamber is a sewage chamber; in the airflow path, the second chamber is located downstream of the first chamber, and the airflow entering the sewage bucket through the sewage inlet pipe enters the second chamber from the air inlet and leaves the sewage bucket from the second chamber air outlet, achieving gas-liquid separation, that is, the second chamber is equivalent to the gas-liquid separation chamber, and the channel from the air inlet to the second chamber air outlet is the gas-liquid separation channel of the second chamber. Gas-liquid separation is achieved by adjusting the cross-sectional area of ​​the gas-liquid separation channel. At the same time, since the height of the air inlet is lower than the height of the sewage inlet pipe outlet, the two are staggered in the horizontal direction, preventing sewage ejected from the sewage inlet pipe outlet due to negative pressure from directly entering the second chamber through the air inlet, causing water to enter the fan.

[0008] During the operation of the cleaning device of the present invention, when the cleaning device is in a lying state, the airflow drives the water to flow out from the outlet of the sewage inlet pipe, and the airflow can flow from the first chamber through the air inlet to the second chamber, and leave the sewage bucket from the air outlet of the second chamber. Even if the sewage in the sewage bucket splashes during the user's pushing and pulling process, it will remain in the first chamber under the obstruction of the second partition, avoiding the fan unit from malfunctioning due to water inlet, effectively extending the service life of the cleaning device of the present invention, and thus improving the user experience.

[0025] The present disclosure provides a cleaning device for cleaning work surfaces such as floors and carpets. Specifically, the cleaning device comprises at least a body and a sewage bucket, wherein the sewage bucket comprises at least a bucket cover and a bucket body that are buckled together to form an inner cavity, and a sewage inlet pipe located in the inner cavity.

[0026] It will be understood that in the cleaning device of the present disclosure, a sewage suction pipe is provided at the bottom of the body, and with the cleaning device moving in the forward direction, a sewage bucket is provided at the rear side of the body, and the bottom opening of the sewage bucket's sewage inlet pipe is connected to the sewage suction pipe. During operation of the cleaning device of the present disclosure, the fan unit provided within the body can generate negative pressure within the inner cavity of the sewage bucket through airflow, thereby allowing sewage on the working surface to be drawn into the inner cavity of the sewage bucket through the sewage inlet pipe under the action of the negative pressure.

[0027] Specifically, the inner cavity includes a first chamber and a second chamber connected to the first chamber, wherein the sewage inlet pipe is at least partially located in the first chamber, the first chamber is used to accommodate sewage entering through the sewage inlet pipe, and the second chamber is located downstream of the first chamber, and the air flow entering the sewage bucket through the sewage inlet pipe leaves the sewage bucket through the air outlet of the second chamber;

[0028] The second chamber includes a bottom wall protruding outward from the side wall of the barrel body; the barrel cover is provided with a first partition and a second partition extending in the vertical direction of the sewage barrel, and the outlet of the sewage inlet pipe is located between the first partition and the second partition; wherein the second partition is arranged at a position where the first chamber and the second chamber are connected, and an air inlet connecting the first chamber and the second chamber is formed between the second partition and the bottom wall, and the height of the air inlet is lower than the height of the outlet of the sewage inlet pipe.

[0029] The sewage inlet pipe is at least partially located in the first chamber, which is used to accommodate sewage entering through the sewage inlet pipe, that is, the first chamber is a sewage chamber; in the airflow path, the second chamber is located downstream of the first chamber, and the airflow entering the sewage bucket through the sewage inlet pipe enters the second chamber from the air inlet and leaves the sewage bucket from the second chamber air outlet, achieving gas-liquid separation, that is, the second chamber is equivalent to the gas-liquid separation chamber, and the channel from the air inlet to the second chamber air outlet is the gas-liquid separation channel of the second chamber. Gas-liquid separation is achieved by adjusting the cross-sectional area of ​​the gas-liquid separation channel. At the same time, because the height of the air inlet is lower than the height of the sewage inlet pipe outlet, the two are staggered in the horizontal direction, preventing sewage ejected from the sewage inlet pipe outlet due to negative pressure from directly entering the second chamber through the air inlet, causing water to enter the fan.

[0030] During the operation of the cleaning device of the present invention, when the cleaning device is in a lying state, the airflow drives the water to flow out from the outlet of the sewage inlet pipe, and the airflow can flow from the first chamber through the air inlet to the second chamber, and leave the sewage bucket from the air outlet of the second chamber. Even if the sewage in the sewage bucket splashes during the user's pushing and pulling process, it will remain in the first chamber under the obstruction of the second partition, avoiding the fan unit from malfunctioning due to water inlet, effectively extending the service life of the cleaning device of the present invention, and thus improving the user experience.

[0031] For ease of understanding, refer to Figures 1 to 8 , the specific structure and working principle of the cleaning device disclosed in the present invention are explained in detail with reference to an embodiment.

[0032] like Figure 1 and Figure 2 As shown, the present disclosure provides a cleaning device for cleaning work surfaces such as floors and carpets. Specifically, the cleaning device includes at least a body 2 and a sewage bucket 1. The sewage bucket 1 includes at least a bucket cover 10 and a bucket body 20 that are buckled together to form an inner cavity 40, and a sewage inlet pipe 30 located in the inner cavity 40.

[0033] It will be appreciated that, in the cleaning device of the present disclosure, a sewage suction pipe is provided at the bottom of the main body 2. With the cleaning device moving forward, the sewage bucket 1 is provided at the rear side of the main body 2, and the bottom opening of the sewage inlet pipe 30 of the sewage bucket 1 is connected to the sewage suction pipe. During operation of the cleaning device of the present disclosure, the fan unit provided within the main body 2 is capable of generating negative pressure within the inner cavity 40 of the sewage bucket 1 through airflow, thereby allowing sewage on the working surface to be drawn into the inner cavity 40 of the sewage bucket 1 along the sewage inlet pipe 30 under the action of the negative pressure.

[0034] Specifically, such as Figure 3 and Figure 4 As shown, the inner cavity 40 includes a first chamber 41 and a second chamber 42 communicating with the first chamber 41, wherein the sewage inlet pipe 30 is at least partially located in the first chamber 41, and the first chamber 41 is used to accommodate sewage entering through the sewage inlet pipe 30. In the negative pressure recovery airflow path, the second chamber 42 is located downstream of the first chamber 41. The airflow entering the first chamber 41 of the sewage bucket 1 through the sewage inlet pipe 30 leaves the sewage bucket 1 through the air outlet 45 of the second chamber 42;

[0035] The second chamber 42 includes a bottom wall 21 protruding outward from the side wall of the barrel body 20; the barrel cover 10 is provided with a first partition 11 and a second partition 12 extending in the vertical direction of the sewage barrel 1, and the outlet of the sewage inlet pipe 30 is located between the first partition 11 and the second partition 12; wherein, the second partition 12 is arranged at a position where the first chamber 41 and the second chamber 42 are connected, and an air inlet 43 connecting the first chamber 41 and the second chamber 42 is formed between the second partition 12 and the bottom wall 21. The height of the air inlet 43 is lower than the height of the outlet of the sewage inlet pipe 30, and the two are staggered in the horizontal direction, which is perpendicular to the axis 1 of the sewage barrel.

[0036] Since the sewage inlet pipe 30 is at least partially located in the first chamber 41, the first chamber 41 is used to accommodate the sewage entering through the sewage inlet pipe 30, that is, the first chamber 41 is a sewage chamber; in the airflow path, the second chamber 42 is located downstream of the first chamber 41. The airflow entering the sewage bucket 1 through the sewage inlet pipe 30 enters the second chamber 42 from the air inlet 43 and leaves the sewage bucket 1 from the air outlet 45 of the second chamber 42, achieving gas-liquid separation. That is, the second chamber 42 is equivalent to the gas-liquid separation chamber, and the channel between the air inlet 43 and the air outlet 45 of the second chamber 42 is the gas-liquid separation channel of the second chamber 42. Gas-liquid separation is achieved by adjusting the cross-sectional area of ​​the gas-liquid separation channel. At the same time, since the height of the air inlet 43 is lower than the height of the sewage inlet pipe 30 outlet, the two are staggered in the horizontal direction, preventing sewage ejected from the sewage inlet pipe 30 outlet due to negative pressure from directly entering the second chamber 42 through the air inlet 43, causing water ingress to the fan.

[0037] During the operation of the cleaning device of the present invention, when the cleaning device is in a lying state, the airflow drives the water to flow out from the outlet of the sewage inlet pipe 30, and the airflow can flow from the first chamber 41 through the air inlet 43 to the second chamber 42, and leave the sewage bucket 1 from the air outlet 45 of the second chamber 42. Even if the sewage in the sewage bucket 1 splashes during the user's pushing and pulling process, it will remain in the first chamber 41 under the obstruction of the second partition 12, thereby avoiding the fan unit from malfunctioning due to water inlet, effectively extending the service life of the cleaning device of the present invention, and thus improving the user experience.

[0038] like Figure 4 As shown, in one embodiment of the present disclosure, the second chamber 42 and the first chamber 41 are arranged side by side in the horizontal direction of the sewage bucket 1, and the bottom wall 21 of the second chamber 42 is closer to the bucket cover 10 than the bottom of the first chamber 41. Since the second chamber 42 and the first chamber 41 are arranged side by side in the horizontal direction of the sewage bucket 1, and the bottom wall 21 of the second chamber 42 is closer to the bucket cover 10 than the bottom of the first chamber 41, the volume of the second chamber 42 can be effectively compressed while ensuring the volume of the first chamber 41, thereby saving the overall volume of the sewage bucket 1 of the present disclosure while ensuring that the sewage bucket 1 of the present disclosure can accommodate the amount of sewage bucket 1.

[0039] like Figure 3 and Figure 4 As shown, in one embodiment of the present disclosure, the space of the second chamber 42 is defined by the bottom wall 21, the side wall of the barrel body 20, the second partition 12, and the barrel cover 10, wherein the horizontal cross-sectional area between the second partition 12 and the side wall of the barrel body 20 is larger than the area of ​​the air inlet 43. Since the horizontal cross-sectional area between the second partition 12 and the side wall of the barrel body 20 is larger than the area of ​​the air inlet 43, the flow rate of the airflow from the air inlet 43 to the interior of the second chamber 42 is slowed down. The water vapor carried in the airflow can be retained in the second chamber 42 under the action of its own gravity, and will not enter the fan unit with the airflow, thereby avoiding malfunction of the fan unit due to water ingress, effectively extending the service life of the cleaning device of the present disclosure, and thus improving the user experience.

[0040] Furthermore, in one embodiment of the present disclosure, any horizontal cross-sectional area between the second partition 12 and the side wall of the second chamber 42 is larger than the area of ​​the air inlet 43. Since any horizontal cross-sectional area between the second partition 12 and the side wall of the second chamber 42 is larger than the area of ​​the air inlet 43, it can be ensured that the flow rate of the airflow from the air inlet 43 to the interior of the second chamber 42 will be greatly slowed down, ensuring that the water vapor carried in the airflow can remain in the second chamber 42 under the action of its own gravity.

[0041] like Figure 3As shown, a connecting wall 22 is provided on the same side of the first partition 11 and the second partition 12, and the connecting wall 22 is constructed to extend beyond the bottom of the second partition 12; the connecting wall 22 and the first partition 11 and the second partition 12 form a water retaining space surrounding the outlet of the sewage inlet pipe 30; the bottom of the second partition 12 and the connecting walls 22 and the bottom wall 21 on both sides form an air inlet 43.

[0042] That is Figure 3 As shown, connecting walls 22 are respectively provided on both sides of the first partition 11 and the second partition 12, and the connecting walls 22 extend beyond the bottom of the second partition 12. In this way, the connecting walls 22 on both sides and the first partition 11 and the second partition 12 form a water retaining space surrounding the outlet of the sewage inlet pipe 30. After the sewage flows out of the outlet of the sewage inlet pipe 30, it will enter the water retaining space and then be blocked by the two connecting walls 22, the first partition 11 and the second partition 12 arranged around it, thereby reducing the potential energy of the sewage when it leaves the sewage inlet pipe 30 due to negative pressure, and preventing the sewage from entering the second chamber 42 when the potential energy is large, making it impossible to separate the water vapor in the airflow through the corresponding gas-liquid separation structure.

[0043] Moreover, the bottom of the second partition 12 and the connecting walls 22 and the bottom wall 21 on both sides form an air inlet 43. The area of ​​the air inlet 43 can be adjusted by adjusting the distance between the bottom of the second partition 12 and the bottom wall 21 and the distance between the connecting walls 22 on both sides, so as to achieve a cross-sectional area of ​​the second chamber 42 perpendicular to the axial direction of the barrel body 20 that is larger than the area of ​​the air inlet 43.

[0044] Of course, in other embodiments, both sides of the first partition 11 and the second partition 12 may also directly abut against the side walls of the barrel body 20 to replace the function of the connecting wall 22 .

[0045] like Figure 4 As shown, in one embodiment of the present disclosure, the top of the first chamber 41 is formed by the bucket cover 10. At least a portion of the surface of the bucket cover 10 faces the outlet of the sewage inlet pipe 30 to block the sewage flowing out of the sewage inlet pipe 30. That is, the inner top surface of the water-retaining space is the bottom surface of the bucket cover 10. When the sewage flows out of the outlet along the sewage inlet pipe 30, if the sewage flows at a high speed, the sewage will impact the bottom surface of the bucket cover 10 directly above the outlet. In other words, the bottom surface of the bucket cover 10 can serve as a water barrier to block the flow of sewage, and there is no need to provide a separate water barrier.

[0046] like Figure 4 As shown, in one embodiment of the present disclosure, the ratio of the vertical distance between the bottom edge of the second partition 12 and the bottom wall 21 and the vertical distance between the tub cover 10 and the bottom wall 21 is greater than 1:3.

[0047] After actual measurement, when the ratio of the vertical distance from the bottom edge of the second partition 12 to the bottom wall 21 to the vertical distance from the barrel cover 10 to the bottom wall 21 is greater than 1:3, it is possible to ensure that the vertical distance from the bottom edge of the second partition 12 to the bottom wall 21 is sufficient while minimizing the entry of water vapor into the second chamber 42, thereby ensuring smooth airflow.

[0048] like Figure 4 and Figure 5 As shown, in one embodiment of the present disclosure, the second partition plate 12 is provided with a first inclined portion 121 that is inclined toward the outlet, and at least a portion of the first inclined portion 121 is higher than the outlet. In this way, as the air flows from the water retaining space to the air inlet 43, the first inclined portion 121 can guide the airflow away from the second partition plate 12, thereby reducing the water vapor content in the airflow entering the air inlet 43.

[0049] like Figure 4 and Figure 5 As shown, in one embodiment of the present disclosure, the second partition 12 is provided with a second inclined portion 122, which is inclined toward the sewage inlet pipe 30 and is lower than the outlet. Thus, as the air flows from the gap between the second partition 12 and the sewage inlet pipe 30 toward the air inlet 43, the second inclined portion 122 can also guide the airflow away from the second partition 12, allowing some water vapor in the airflow to fall onto the sewage inlet pipe 30, further reducing the water vapor content of the airflow entering the air inlet 43.

[0050] like Figure 4 As shown, in one embodiment of the present disclosure, the horizontal distance between the second inclined portion 122 and the sewage inlet pipe 30 is smaller than the horizontal distance between the second inclined portion 122 and the side wall of the second chamber 42 corresponding to the second inclined portion 122, thereby ensuring that the horizontal distance between the second inclined portion 122 and the sewage inlet pipe 30 is small, and can effectively guide the airflow to flow to the side away from the second partition 12, while the horizontal distance between the second inclined portion 122 and the side wall of the second chamber 42 corresponding to the second inclined portion 122 is large, so that when the cleaning equipment is in a lying state, part of the water vapor in the second chamber 42 can fall onto the second partition 12 during the upward flow of the airflow, thereby further reducing the water vapor content in the fan unit.

[0051] like Figure 4 As shown, in one embodiment of the present disclosure, the inclination angle of the second inclined portion 122 is no greater than the inclination angle of the first inclined portion 121. That is, the gap between the second inclined portion 122 and the sewage inlet pipe 30 is small. To prevent solid dirt in the airflow from adhering to the second inclined portion 122, the inclination angle of the second inclined portion 122 does not exceed 45 degrees, thereby preventing sewage blockage between the second inclined portion 122 and the sewage inlet pipe 30 after the cleaning device of the present disclosure has been in operation for a long time.

[0052] Specifically, in one embodiment of the present disclosure, the inclination angle of the first inclined portion 121 is 45 degrees, and the inclination angle of the second inclined portion 122 is 30 degrees. After testing, it was found that when the inclination angle of the first inclined portion 121 is 45 degrees and the inclination angle of the second inclined portion 122 is 30 degrees, the water vapor content in the air flow entering the air inlet 43 can be effectively reduced, and the blockage between the second inclined portion 122 and the sewage inlet pipe 30 after the cleaning device of the present disclosure has been operated for a long time can be avoided. In another embodiment of the present disclosure, the inclination angles of the first inclined portion 121 and the second inclined portion 122 can be set as needed and are not limited here.

[0053] like Figure 4 As shown, in one embodiment of the present disclosure, the horizontal cross-sectional area formed between the second partition plate 12 and the sidewall of the second chamber 42 is a region 421 of continuously varying horizontal cross-sectional area at the first and second inclined portions 122. It can be seen that the cross-sectional area of ​​the region 421 of continuously varying horizontal cross-sectional area is greater than the cross-sectional area of ​​the adjacent region below. When the airflow flows from the region below the expansion slot in the second chamber 42 to the region 421 of continuously varying horizontal cross-sectional area, the flow velocity of the airflow slows down a second time, further allowing the water vapor carried in the airflow to be retained as much as possible in the region below the expansion slot in the second chamber 42 under the action of its own gravity, rather than entering the fan unit with the airflow.

[0054] like Figure 4 As shown, in one embodiment of the present disclosure, the first partition 11 includes a sealing section 111, which is constructed in the shape of a closed plate and extends downward beyond the bottom wall 21, and the bottom wall 21 is constructed to be inclined downward toward the side of the first chamber 41. Since the sealing section 111 is in the shape of a closed plate and extends downward beyond the bottom wall 21, when the cleaning device is in a flat state, even if the sewage under the first partition 11 shakes back and forth and causes liquid splashing during the process of the user repeatedly pushing and pulling the cleaning device, it will be blocked by the sealing section 111 under the first partition 11. Since the bottom wall 21 is inclined downward toward the side of the first chamber 41, liquid that accidentally enters the second chamber 42 or converges downward in the second chamber 42 can flow into the first chamber 41 along the inclined bottom wall 21, thereby preventing the liquid accumulated in the first chamber 41 from being unable to be removed, causing water vapor to enter the fan unit.

[0055] like Figure 4As shown, in one embodiment of the present disclosure, a wave-suppressing inclined section 113 is provided at the bottom of the first partition 11. The wave-suppressing inclined section 113 is configured to extend downward at an angle. When the body 2 of the cleaning device of the present disclosure is tilted or lying flat, and a user repeatedly pushes and pulls the body 2, causing sewage waves to form within the sewage bucket 1, the wave-suppressing inclined section 113 can effectively suppress the splashes formed by the waves in the inner cavity 40 of the sewage bucket 1 hitting the wall, thereby reducing the water vapor content in the airflow.

[0056] like Figure 4 and Figure 5 As shown, in one embodiment of the present disclosure, a second chamber 42 is defined as being located at the front, and a first chamber 41 is located at the rear. A filter mounting slot 451 extending outward from the top of the lid 10 for mounting a filter forms an air outlet 45. The bottom of the filter mounting slot 451 extends downward into the second chamber 42 to form a vent 44, which is positioned toward the front wall of the barrel body 20. Thus, when the cleaning device of the present disclosure is in a flat position, the vent 44 is located at the top of the second chamber 42. This ensures that airflow must flow upward through the vent 44 before reaching the air outlet 45. This further allows moisture carried in the airflow to be retained in the second chamber 42 under its own gravity, rather than entering the fan unit. When airflow passes through the vent 44, it deflects, and some moisture carried in the airflow forms droplets upon contacting the top wall of the second chamber 42 and flowing downward.

[0057] like Figure 4 As shown, in one embodiment of the present disclosure, the height of the bottom surface of the bung cover 10 directly opposite the outlet of the sewage inlet pipe 30 is greater than the height of the vent 44. Since the height of the bottom surface of the bung cover 10 directly opposite the outlet of the sewage inlet pipe 30 is greater than the height of the vent 44, the required flow distance of the sewage can be effectively increased, and the potential energy of the sewage is reduced by the distance, thereby reducing the amount of sewage impacting the end surface of the bung cover 10, thereby reducing the amount of water splashing around due to the impact of the sewage and the bung cover 10, and minimizing the amount of splashing water from falling into the second chamber 42.

[0058] like Figure 4 and Figure 5 As shown, in one embodiment of the present disclosure, a swirl groove 423 is provided on the rear side of the vent 44, which is formed between the second partition plate 12 and the bottom wall 21 of the filter element mounting groove 451. When the airflow flows along the second chamber 42, the gas flowing to one side of the vent 44 will flow out from the air outlet 45, while the gas flowing to the side of the swirl groove 423 will swirl in the swirl groove 423, causing the originally upward-flowing airflow to turn to flow downward, thereby offsetting the potential energy of other upward-flowing airflows and reducing the flow speed of the upward-flowing gas on the other side. The water vapor carried in the airflow will form water droplets when it contacts the inner walls of the second chamber 42, so as to prevent the water vapor in the airflow from directly entering the fan unit as much as possible.

[0059] like Figure 3 and Figure 4 As shown, in one embodiment of the present disclosure, the vent 44 is covered with a baffle 441 , and the baffle 441 is provided with an air outlet hole. The baffle 441 is used to prevent solid dirt, such as lint, from entering the fan unit.

[0060] like Figure 4 As shown, in one embodiment of the present disclosure, the centerline of the sewage inlet pipe 30 is configured to be located outside the projection of the filter element mounting groove 451 on the cross-section of the sewage bucket 1. Because the centerline of the sewage inlet pipe 30 is located outside the projection of the filter element mounting groove 451 on the cross-section of the sewage bucket 1, the air outlet 45 of the present disclosure can be positioned above the second chamber 42. As a result, when the cleaning device of the present disclosure is used in a tilted or flat position, the air vent 44 connected to the air outlet 45 is positioned on the upper side of the barrel body 20 and closer to the front, away from the sewage liquid surface.

[0061] like Figures 1 to 4 As shown, the present disclosure provides a cleaning device, including a sewage bucket 1, the sewage bucket 1 includes a bucket cover 10 and a barrel body 20 that are buckled together and enclose an inner cavity 40, and a sewage inlet pipe 30 located in the inner cavity 40; the inner cavity 40 includes a first chamber 41 and a second chamber 42 connected to the first chamber 41, the second chamber 42 is constructed to be adjacent to one side of the first chamber 41, and is constructed to extend horizontally on a surface perpendicular to the axis of the barrel body 20; the bucket cover 10 is provided with a first partition 11 and a second partition 12 extending along the axial direction of the sewage bucket 1, the sewage inlet pipe 30 is located in the first chamber 41 and is located between the first partition 11 and the second partition. 12; wherein, the second partition 12 is arranged at a position where the first chamber 41 and the second chamber 42 are connected, and is constructed to participate in forming an air inlet 43 connecting the first chamber 41 and the second chamber 42; the second partition 12 is provided with a first inclined portion 121 inclined toward the outlet direction of the sewage inlet pipe 30, and at least part of the first inclined portion 121 is located at a position higher than the outlet; the second partition 12 is provided with a second inclined portion 122 at a position below the first inclined portion 121, and the second inclined portion 122 is constructed from top to bottom to be inclined toward the direction of the sewage inlet pipe 30; the second inclined portion 122 is located below the outlet.

[0062] In this way, when the air flow flows from the water retaining space to the air inlet 43, the first inclined portion 121 can guide the air flow to the side away from the second partition 12, thereby reducing the water vapor content in the air flow entering the air inlet 43; the second inclined portion 122 can also guide the air flow to the side away from the second partition 12, so that part of the water vapor in the air flow can fall onto the sewage inlet pipe 30, thereby further reducing the water vapor content in the air flow entering the air inlet 43.

[0063] like Figure 6 As shown, the present disclosure provides a cleaning device, including a body 2 and a sewage bucket 1, the sewage bucket 1 is arranged on the body 2, and includes a bucket cover 10 and a bucket body 20; the bucket cover 10 and the bucket body 20 are constructed to enclose an inner cavity 40; the sewage bucket 1 also includes a water full detection probe 50 arranged on the bucket cover 10, and the detection point of the water full detection probe 50 is configured to trigger a water full signal when immersed in water; the body 2 has a vertical state, an inclined state and a lying state. In the vertical state, the sewage bucket 1 has a first water level line when it is full of water, in the inclined state, the sewage bucket 1 has a second water level line when it is full of water, and in the lying state, the sewage bucket 1 has a third water level line when it is full of water, and the first, second and third water level lines intersect at the detection point of the water full detection probe 50.

[0064] Since the body 2 has a vertical state, an inclined state and a lying flat state, in the vertical state, the sewage bucket 1 has a first water level line when it is full of water, in the inclined state, the sewage bucket 1 has a second water level line when it is full of water, and in the lying flat state, the sewage bucket 1 has a third water level line when it is full of water. The first, second and third water level lines intersect at the detection point of the water full detection probe 50. Therefore, the water full detection probe 50 disclosed in the present invention can detect sewage in the inner cavity 40 of the sewage bucket 1 in the vertical state, the inclined state and the lying flat state, thereby effectively expanding the applicability of the water full detection probe 50 disclosed in the present invention.

[0065] like Figure 4 As shown, in one embodiment of the present disclosure, the inner cavity 40 includes a first chamber 41 and a second chamber 42 laterally connected to the first chamber 41; the water full detection probe 50 is located in the first chamber 41, is cylindrical and its end is a detection point, and the water full detection probe 50 extends vertically downward and exceeds the bottom wall 21 of the second chamber 42.

[0066] Since the water full detection probe 50 is columnar and its end is the detection point, the water full detection probe 50 extends vertically downward and exceeds the bottom wall 21 of the second chamber 42, which can effectively ensure that the first, second and third water level lines of the fuselage 2 when the fuselage 2 is in a vertical state, an inclined state and a lying flat state intersect at the detection point of the water full detection probe 50.

[0067] like Figure 7 and Figure 8As shown, the present disclosure provides a cleaning device, which includes a body 2 and a sewage bucket 1. The sewage bucket 1 is arranged on the body 2 and includes a bucket cover 10 and a bucket body 20; the bucket cover 10 and the bucket body 20 are constructed to enclose an inner cavity 40; the sewage bucket 1 also includes a water full detection probe 50 arranged on the bucket cover 10, and the water full detection probe 50 includes a first probe 51 and a second probe 52 arranged on the first side of the sewage inlet pipe 30, and a third probe 53 and a fourth probe 54 arranged on the second side of the sewage inlet pipe 30, the first probe 51 and the third probe 53 are arranged on the front side of the bucket cover 10, and the second probe 52 and the fourth probe 54 are arranged on the rear side of the bucket cover 10, and the length of the first probe 51 and the third probe 53 is smaller than the length of the second probe 52 and the fourth probe 54; the first probe 51 and the fourth probe 54 are configured to trigger a water full signal when they are simultaneously immersed in sewage, and the second probe 52 and the third probe 53 are configured to trigger a water full signal when they are simultaneously immersed in sewage.

[0068] In this way, during the operation of the cleaning device disclosed herein, when the body 2 is in a flat state, no matter whether the body 2 is rotated to a certain angle to the left or right, it can be ensured that the water full detection probe 50 can detect the water level condition when the body 2 is rotated to a certain angle, and there will be no problem of late or early reporting. The risk of water entering the motor due to inaccurate detection can be effectively reduced, the product reliability can be improved, and the user experience can be effectively improved.

[0069] like Figure 8 As shown, the bottoms of the second probe 52 and the fourth probe 54 may be provided with bending sections to ensure that the cleaning device of the present disclosure can be triggered when the sewage in the sewage bucket 1 reaches a certain amount in both the tilted state and the flat state.

[0070] Application Scenario

[0071] The present disclosure provides a cleaning device for cleaning work surfaces such as floors and carpets. Specifically, the cleaning device includes at least a body 2 and a sewage bucket 1. The sewage bucket 1 includes at least a bucket cover 10 and a bucket body 20 that are fastened together to form an inner cavity 40, and a sewage inlet pipe 30 located in the inner cavity 40.

[0072] It will be appreciated that, in the cleaning device of the present disclosure, a sewage suction pipe is provided at the bottom of the main body 2. With the cleaning device moving forward, the sewage bucket 1 is provided at the rear side of the main body 2, and the bottom opening of the sewage inlet pipe 30 of the sewage bucket 1 is connected to the sewage suction pipe. During operation of the cleaning device of the present disclosure, the fan unit provided within the main body 2 is capable of generating negative pressure within the inner cavity 40 of the sewage bucket 1 through airflow, thereby allowing sewage on the working surface to be drawn into the inner cavity 40 of the sewage bucket 1 along the sewage inlet pipe 30 under the action of the negative pressure.

[0073] Specifically, the inner cavity 40 includes a first chamber 41 and a second chamber 42 communicating with the first chamber 41 , wherein the sewage inlet pipe 30 is at least partially located in the first chamber 41 , and the first chamber 41 is used to accommodate sewage entering through the sewage inlet pipe 30 . The second chamber 42 is located downstream of the first chamber 41 , and the airflow entering the sewage bucket 1 through the sewage inlet pipe 30 leaves the sewage bucket 1 through the air outlet 45 of the second chamber 42 ;

[0074] The second chamber 42 includes a bottom wall 21 protruding outward from the side wall of the barrel body 20; the barrel cover 10 is provided with a first partition 11 and a second partition 12 extending in the vertical direction of the sewage barrel 1, and the outlet of the sewage inlet pipe 30 is located between the first partition 11 and the second partition 12; wherein, the second partition 12 is arranged at a position where the first chamber 41 and the second chamber 42 are connected, and an air inlet 43 connecting the first chamber 41 and the second chamber 42 is formed between the second partition 12 and the bottom wall 21, and the height of the air inlet 43 is lower than the height of the outlet of the sewage inlet pipe 30, and the two are staggered in the horizontal direction.

[0075] Since the sewage inlet pipe 30 is at least partially located in the first chamber 41, the first chamber 41 is used to accommodate the sewage entering through the sewage inlet pipe 30, that is, the first chamber 41 is a sewage chamber; in the airflow path, the second chamber 42 is located downstream of the first chamber 41. The airflow entering the sewage bucket 1 through the sewage inlet pipe 30 enters the second chamber 42 from the air inlet 43 and leaves the sewage bucket 1 from the air outlet 45 of the second chamber 42, achieving gas-liquid separation. That is, the second chamber 42 is equivalent to the gas-liquid separation chamber, and the channel between the air inlet 43 and the air outlet 45 of the second chamber 42 is the gas-liquid separation channel of the second chamber 42. Gas-liquid separation is achieved by adjusting the cross-sectional area of ​​the gas-liquid separation channel. At the same time, since the height of the air inlet 43 is lower than the height of the sewage inlet pipe 30 outlet, the two are staggered in the horizontal direction, preventing sewage ejected from the sewage inlet pipe 30 outlet due to negative pressure from directly entering the second chamber 42 through the air inlet 43, causing water ingress to the fan.

[0076] During the operation of the cleaning device of the present invention, when the cleaning device is in a lying state, the airflow drives the water to flow out from the outlet of the sewage inlet pipe 30, and the airflow can flow from the first chamber 41 through the air inlet 43 to the second chamber 42, and leave the sewage bucket 1 from the air outlet 45 of the second chamber 42. Even if the sewage in the sewage bucket 1 splashes during the user's pushing and pulling process, it will remain in the first chamber 41 under the obstruction of the second partition 12, thereby avoiding the fan unit from malfunctioning due to water inlet, effectively extending the service life of the cleaning device of the present invention, and thus improving the user experience.

[0077] The embodiments of the present disclosure have been described above. The above description is exemplary, not exhaustive, and is not limited to the disclosed embodiments. Many modifications and variations will be apparent to those skilled in the art without departing from the scope and spirit of the described embodiments.
