Description

Technical Field

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

[0002] Surface cleaning equipment with clean water delivery is a common device for cleaning the floor. Clean water is guided toward the roller brush structure of the floor scrubber through the pipe assembly in the cleaning head. The roller continuously rubs against the floor through rotation to clean the surface. Some existing cleaning tools use two suction parts to completely separate the clean water part and the sewage part. The first suction part is used to suck the clean water, and then use the clean water to clean the roller brush. The second suction part is used to suck the sewage into the sewage tank; some cleaning tools use the clean water suction part to drive the flow of clean water, and integrate the clean water part and the sewage part into one, so that the clean water that wets the roller is directly mixed with the sewage peeled off from the bottom of the roller, and the flow of clean water is used to drive the flow of sewage. The direct mixing of clean water and sewage makes the roller wet with sewage when it is wet, which has a poor cleaning effect on the roller. Summary of the invention

[0003] The purpose of the present invention is to provide a cleaning tool with a simple structure and good cleaning effect.

[0004] To achieve the above-mentioned purpose, the cleaning tool disclosed in the present invention includes a cleaning head, a clean water tank and a sewage tank, the sewage tank is detachably connected to the cleaning head, the cleaning head includes a body and a drum, the body has a clean water tank and a sewage tank, the clean water tank is connected to the clean water tank, the liquid in the clean water tank is used to wet the surface of the drum, the sewage tank is used to collect sewage on the drum, the sewage tank is connected to the sewage tank, the clean water tank is connected to the sewage tank, and the liquid in the clean water tank flows into the sewage tank through the sewage tank.

[0005] It can be seen from the above technical scheme that the liquid flows from the clean water tank to the clean water trough to wet the surface of the drum, which is convenient for cleaning the cleaning surface. The liquid continues to flow to the sewage trough and merges with the sewage in the sewage trough. That is, the liquid in the clean water trough can drive the sewage in the sewage trough to flow to the sewage tank, thereby improving the sewage collection efficiency, and no other power components are required to drive the sewage to achieve rapid sewage collection, making the cleaning tool structure simpler, which can reduce production costs, reduce the weight of cleaning tools, and improve user experience. The sewage trough collects sewage on the drum, reducing the possibility of sewage splashing and spilling; by separately setting the sewage trough and the clean water trough, the sewage in the sewage trough does not interfere with the liquid in the clean water trough, preventing secondary pollution of the drum and improving the cleaning performance of the cleaning tool; the sewage tank and the cleaning head are detachably connected, which is convenient for users to dump the liquid in the sewage tank and clean the sewage tank, thereby improving the convenience of using cleaning tools.

[0006] The body has a first connecting groove, the first connecting groove connects the clean water tank and the sewage tank, the connection between the first connecting groove and the clean water tank has a clean water tank outlet, the connection between the first connecting groove and the sewage tank has a sewage tank inlet, and the height of the clean water tank outlet is higher than the height of the sewage tank inlet. The advantage is that the clean water tank outlet end of the first connecting groove is higher than the sewage tank inlet end of the first connecting groove. When the liquid enters the first connecting groove from the clean water tank, the liquid can pass through the first connecting groove under the action of gravity and enter the sewage tank, converting the gravity of the liquid into the power of flow, improving the smoothness of the liquid flow and the impact performance of the liquid entering the sewage tank, thereby improving the fluidity of the sewage. At the same time, when the liquid flow is stopped, a smaller siphon phenomenon will be generated. The first connecting groove can reduce the possibility of sewage in the sewage tank entering the clean water tank when the siphon phenomenon occurs.

[0007] The cleaning tool includes a rod assembly, the clean water tank is located on the rod assembly, and the height of the clean water tank is higher than the height of the clean water tank; or, the rod assembly also includes a water pump, and the water pump drives the liquid in the clean water tank into the clean water tank. The advantage is that the clean water tank is located on the rod assembly, and when the rod assembly is upright or tilted relative to the cleaning ground, the height of the clean water tank on the rod assembly is higher than the height of the clean water tank on the cleaning head, so that the liquid can flow from the clean water tank to the clean water tank under the action of gravity, and then wet the roller; the use of the water pump can increase the flow speed of the liquid, improve the stability of the liquid entering the clean water tank, and reduce the possibility of large changes in the flow speed of the liquid due to the height difference between the clean water tank and the clean water tank.

[0008] The cleaning head includes a top cover, the main body includes a water purification part, the water purification part includes a first baffle and a second baffle, the first baffle and the second baffle are arranged side by side and maintain a certain distance, the top cover is at least partially located above the first baffle and the second baffle, the first baffle and the second baffle are both against the top cover, the lower end of the first baffle is close to the surface of the drum, the first baffle, the second baffle and the top plate together form the water purification trough, and the opening of the water purification trough faces the drum. The advantage is that two first baffles, second baffles and top cover arranged side by side form a clean water trough, and the opening of the clean water trough faces the drum, and the liquid in the clean water trough flows between the first baffle and the second baffle. The first baffle is close to the drum, which can not only wet the surface of the drum and reduce the possibility of clean water flowing out along the drum surface, but also reduce the possibility of the first baffle interfering with the drum surface, resulting in a low degree of wetness on the drum surface. It can also drive some fine stains on the drum surface, so that the fine stains are washed to the sewage trough under the drive of the liquid, and finally flow into the sewage tank, thereby improving the cleanliness of the drum surface.

[0009] The top cover includes a flexible part and a transparent part, the flexible part abuts against the first barrier rib, and the transparent part is at least partially located directly above the clean water tank. The advantage is that the first barrier rib is sealed with a flexible material, and the vibration between the top cover and the first barrier rib can be reduced when the surface is bumpy or the movement trajectory is changed by other external forces. The elasticity of the flexible material also prevents the liquid in the clean water tank from leaking from the top cover, thereby improving the safety of the cleaning head; the transparent part is located directly above the clean water tank, so that the user can observe the flow of the liquid in the clean water tank, thereby improving the user's visual experience.

[0010] The main body includes a sewage component and a wiper strip, and the sewage component includes a water receiving plate. In the forward direction of the cleaning tool, the roller is located in front of the sewage component, and the wiper strip is located between the water purification component and the sewage component. The wiper strip interferes with the roller and is used to squeeze the sewage on the roller. The water receiving plate guides the sewage to the sewage tank. The advantage is that when the cleaning tool is working, the roller rolls along the forward direction, so that the water purification tank first wets the roller, and the roller contacts the surface to be cleaned to clean the surface, and then the sewage on the roller is cleaned by the wiper strip, and this cycle is used for cleaning work; the water receiving plate guides the sewage to the sewage tank, which reduces the possibility of sewage splashing and leakage, and improves the cleaning performance.

[0011] The sewage component also includes a sewage trough part and a connecting part, wherein the sewage trough is located in the sewage trough part, the sewage trough part is located below the water receiving plate, one end of the connecting part is connected to the sewage trough part, and one end of the connecting part is connected to the top cover. The advantage is that the sewage trough part is located below the water receiving plate, and under the action of the wiper strip, the sewage on the drum can flow into the sewage trough through the water receiving plate by its own gravity, so that the sewage collection is quick and simple, and the possibility of sewage turbulence is reduced; one end of the connecting part is connected to the sewage trough part, which improves the stability of the sewage trough part and enhances the structural strength; the other end of the connecting part is connected to the top cover for supporting the top cover and improving the structural strength of the top cover. At the same time, the top cover, the connecting part, the sewage trough part, the water receiving plate and the wiper strip together form a cavity. Even if the cleaning tool encounters an uneven surface or changes direction due to external force, the sewage is only in the above cavity, which reduces the possibility of leakage to the outside and improves the user experience.

[0012] One end of the water receiving plate is fixedly connected to the sewage trough, and the other end of the water receiving plate is close to the wiper and close to the drum. The advantage is that the water receiving plate is fixedly connected to the sewage trough, which increases the structural strength of both and improves the stability of the sewage trough; the other end of the water receiving plate is close to the wiper, so that the sewage directly enters the water receiving plate after detaching from the drum surface, reducing the accumulation of sewage on the drum surface and the possibility of sewage flowing out along the gap between the components. At the same time, the water receiving plate is close to the drum surface, so that the water receiving plate will neither interfere with the drum to cause sewage to flow out from under the water receiving plate, nor will it cause sewage to flow out from the gap between the water receiving plate and the drum surface, reducing the possibility of sewage leakage and improving user experience.

[0013] The top cover includes a raised portion, and the top cover is rotatable relative to the body, and the top cover can be rotated until the raised portion interferes with the drum. The advantage is that after the top cover is turned over, the drum can be rinsed with external water, and the erected top cover can reduce the impact of the washing water on the cleaning head, thereby improving the convenience of cleaning the drum. At the same time, the top cover interferes with the drum, and the drum can be deeply cleaned during the cleaning process. The top cover can scrape off the stains on the surface of the drum, thereby improving the cleaning effect.

[0014] The top of the sewage tank has an exhaust hole, and a one-way duckbill valve is installed at the exhaust hole. The one-way duckbill valve is made of flexible material. The advantage is that the exhaust hole can balance the air pressure inside and outside the sewage tank, reduce the possibility of sewage entering the sewage tank and causing the air pressure inside the sewage tank to increase, and improve the smoothness of sewage entering the sewage tank; the one-way valve can reduce the possibility of sewage in the sewage tank being spilled during movement or use, avoiding secondary contamination of the clean surface.

DETAILED DESCRIPTION

[0026] The embodiments of the present disclosure are described below with reference to the accompanying drawings.

[0027] Please refer to Figure 1 As shown, the cleaning tool comprises a cleaning head 1 and a rod assembly 4. The rod assembly 4 can stand upright on the cleaning head 1, and the rod assembly 4 is rotatably connected to the cleaning head 1.

[0028] Please refer to Figure 1 and 2 As shown, the cleaning tool further includes a clean water tank 2 and a sewage tank 3. Clean water is provided in the clean water tank 2. The clean water tank 2 is located on the rod assembly 4, and the clean water tank 2 and the rod assembly 4 are detachably connected, so that the clean water tank 2 is conveniently filled with clean water. The sewage tank 3 is used to collect sewage generated by the cleaning tool. The sewage tank 3 is located on the cleaning head 1, and the sewage tank 3 and the cleaning head 1 are detachably connected, so that the user can clean the sewage in the sewage tank 3 and clean the sewage tank 3, thereby improving the convenience of using the cleaning tool and improving the user experience.

[0029] The cleaning head includes a body 11 and a roller 12, the roller 12 is fixedly connected to the body 11, and the roller 12 cleans the ground surface to be cleaned. The body 11 includes a water purification component 13 and a sewage component 14, and the water purification component 13 and the sewage component 14 are both fixedly connected to the body 11, such as welding, etc., to improve the connection strength of the water purification component 13 and the sewage component 14, or the water purification component 13 and the sewage component 14 are both integrally injection molded with the body 11, reducing the production process cost and improving the production efficiency.

[0030] Please refer to Figure 2 As shown, the water purification member 13 includes a water purification tank 131, which is connected to the water purification tank 2, so that the water purification tank 131 can be filled with the clean water in the water purification tank 2, and the drum 12 is located below the water purification member 13. When there is clean water in the water purification tank 131, the drum 12 can be wetted and cleaned, so as to facilitate the cleaning of the surface to be cleaned by the drum 12. When the rod assembly 4 is upright on the cleaning head 1, the water purification tank 2 is located on the rod assembly 4, so that the water purification tank 2 is located above the cleaning head 1. During the use of the cleaning tool, the water purification tank 2 is generally also above the cleaning head 1. At this time, the clean water in the water purification tank 2 can flow from the water purification tank 2 to the water purification tank 131 by the gravity of the clean water itself, so as to realize the flow of clean water. It can be understood that the rod assembly 4 includes a water pump, which can drive the clean water in the clean water tank 2 into the clean water tank 131. The water pump can increase the flow rate of the liquid, improve the stability of the liquid entering the clean water tank, and reduce the possibility of large changes in the liquid flow rate due to the height difference between the clean water tank and the clean water tank.

[0031] Please refer to Figure 2 and Figure 4 As shown, the sewage component 14 includes a sewage trough 1411, and the body 11 includes a wiper strip 18. The sewage trough 1411 is used to carry sewage. The wiper strip 18 interferes with the drum 12. The interference distance D4 between the wiper strip 18 and the drum 12 is between 1 mm and 5 mm, and the interference distance D4 can be 2 mm or 3 mm. After the wiper strip 18 interferes with the drum 12, the sewage in the drum 12 can be squeezed out. The sewage squeezed out by the wiper strip 18 is collected by the sewage trough 1411. The sewage trough 1411 is connected to the sewage tank 3. The sewage in the sewage trough 1411 can flow into the sewage tank 3, avoiding excessive sewage in the sewage trough 1411 and reducing the possibility of splashing and spilling of sewage.

[0032] Please refer to Figure 2 and Figure 5 As shown, the body 11 has a first connecting groove 15, which is located on the side wall of the body 11. The first connecting groove 15 connects the clean water groove 131 and the sewage groove 1411. The clean water in the clean water groove 131 enters the sewage groove 1411 through the first connecting groove 15 during the flow, merges with the sewage in the sewage groove 1411, and drives the sewage in the sewage groove 1411 to flow and enter the sewage tank 3, thereby improving the smoothness of the sewage flow. The clean water in the clean water groove 131 is located upstream of the flow, and the sewage in the sewage groove 1411 is located downstream of the flow, so that the sewage in the sewage groove 1411 does not interfere with the clean water in the clean water groove 131, so that the drum 12 is only wetted by clean water before contacting the surface to be cleaned, thereby improving the cleaning performance of the cleaning tool.

[0033] The connection between the first connection groove 15 and the clean water groove 131 has a clean water groove outlet 1312, and the connection between the first connection groove 15 and the sewage groove 1411 has a sewage groove inlet 1412. The level of the clean water groove outlet 1312 is higher than the level of the sewage groove inlet 1412. It can be understood that the distance between the clean water groove outlet 1312 and the cleaning surface such as the ground is H1, and the distance between the sewage groove inlet 1412 and the cleaning surface such as the ground is H2, and H1 is greater than H2. When the clean water enters the first connection groove 15 from the clean water groove 131, the clean water can pass through the first connection groove 15 under the action of gravity, or the clean water can improve the smoothness of the clean water flow and the impact performance of the clean water entering the sewage groove 1411 by converting the gravitational potential energy into the power of flow, thereby improving the fluidity of the sewage. At the same time, when the clean water stops flowing, a small siphon phenomenon may occur. The first connection groove 15 can reduce the possibility of the sewage in the sewage groove 1411 entering the clean water groove 131 when the siphon phenomenon occurs.

[0034] Please refer to Figure 2 and Figure 6 As shown, the main body 11 has a second connecting groove 16, which is located on the side wall of the main body 11. The second connecting groove 16 connects the sewage groove 1411 and the sewage tank 3. The connection between the second connecting groove 16 and the sewage groove 1411 has a sewage groove outlet 1413, and the connection between the second connecting groove 16 and the sewage tank 3 has a sewage tank inlet 31. The distance between the bottom of the sewage groove outlet 1413 and the ground is higher than the distance between the bottom of the sewage tank inlet 31 and the ground, so that the sewage can flow from the sewage groove outlet 1413 to the sewage tank inlet 31 through the second connecting groove 16 under the action of its own gravity, or the sewage improves the smoothness of the sewage flow by converting gravitational potential energy into flow power.

[0035] Please refer to Fig. 9 As shown, the top of the sewage tank 3 is provided with an exhaust hole 32, and a one-way duckbill valve is installed at the exhaust hole 32. The one-way duckbill valve is made of flexible material. The exhaust hole 32 is set to balance the air pressure inside and outside the sewage tank 3, thereby reducing the possibility of sewage entering the sewage tank 3 and causing the air pressure in the sewage tank 3 to increase, and improving the smoothness of sewage entering the sewage tank 3; the one-way valve setting can reduce the possibility of sewage in the sewage tank 3 being spilled during movement or use, thereby avoiding secondary contamination of the clean surface.

[0036] The liquid in the clean water tank 2 is clean water. The liquid in the clean water tank 2 enters the clean water tank 131 under the action of gravity or a water pump. A part of the liquid is used to wet the drum 12, and a part of the liquid has a partial impact performance, which can drive some fine stains on the surface of the drum 12, so that the fine stains are driven by the liquid and flushed to the sewage tank 1411 through the first connecting groove 15. The part of the clean water liquid that wets the drum 12 contacts the surface to be cleaned on the ground, and becomes sewage after washing the surface to be cleaned. The sewage is squeezed into the sewage tank 1411 under the action of the wiper strip 18. The liquid with impact performance merges with the sewage in the sewage tank 1411. At this time, the clean water becomes sewage, and the liquid is in a sewage state as a whole. At the same time, the sewage is driven to flow into the sewage tank 3.

[0037] Please refer to Figure 2 and Figure 3 As shown, the water purification part 13 includes a first retaining rib 132 and a second retaining rib 133, and the first retaining rib 132 and the second retaining rib 133 are both fixedly connected to the side wall of the body 11, or the first retaining rib 132 and the second retaining rib 133 are integrally injection molded with the side wall of the body 11. The first retaining rib 132 and the second retaining rib 133 are arranged side by side, and the first retaining rib 132 and the second retaining rib 133 keep a distance, a distance D1 between the lower relative areas of the first retaining rib 132 and the second retaining rib 133, and a distance D2 between the middle relative areas of the first retaining rib 132 and the second retaining rib 133, D1 is smaller than D2, and the value of D2 is between 4mm and 8mm. If the distance is too small, the water flow rate will be small, and the function of wetting the drum 12 will not be achieved. If the distance is too large, the water flow rate will be too large, which will waste the water in the clean water tank 2, reduce the cleaning area at one time, and make the user frequently replace the clean water tank 2.

[0038] The cleaning head 1 further includes a top cover 17, which is partially located above the first barrier rib 132 and the second barrier rib 133, and covers the first barrier rib 132, the second barrier rib 133, and the gap between the first barrier rib 132 and the second barrier rib 133. The top cover 17 includes a flexible portion 171, which can be made of soft rubber, such as foamed silica gel, etc. The tops of the first barrier rib 132 and the second barrier rib 133 are both in contact with the flexible portion 171, and the first barrier rib 132 and the second barrier rib 133 are sealed by the flexible material, so that the vibration between the top cover 17 and the first barrier rib 132 and the second barrier rib 133 can be reduced when the surface is bumpy or the movement trajectory is changed by other external forces.

[0039] The clean water tank 131 is formed by a first barrier rib 132, a second barrier rib 133 and a top cover 17. The opening of the clean water tank 131 faces the drum 12. The liquid in the clean water tank 131 flows between the first barrier rib 132 and the second barrier rib 133, so that the liquid in the clean water tank 131 can wet the surface of the drum 12. The elastic properties of the flexible material also prevent the liquid in the clean water tank 131 from leaking from the top cover 17, thereby improving the safety of the cleaning head. The first baffle 132 is close to the drum 12, and the distance between the first baffle 132 and the drum 12 is D3, so that D3 takes a value less than a gap of 2 mm, or the first baffle 132 just touches the surface of the drum 12, that is, D3 takes a value of 0, or the first baffle 132 has a smaller extrusion state on the surface of the drum 12, such as the interference of the first baffle 132 on the drum 12 is less than 0.1 mm, so that the first baffle 132 will neither be too far away from the drum 12, causing the clean water to flow out along the drum surface, nor interfere too deeply with the surface of the drum 12, causing the surface wetness of the drum 12 to be too small, thereby affecting cleaning.

[0040] The distance between the second baffle 133 and the drum 12 is substantially the same as the distance between the first baffle 132 and the drum 12. When the purified water liquid rolls between the first baffle 132 and the second baffle 133, it can drive some fine stains on the surface of the drum 12, so that the fine stains are flushed to the sewage trough 1411 driven by the liquid, and finally flow into the sewage tank 3, thereby improving the cleanliness of the surface of the drum 12 and further improving the cleaning effect of the cleaning tool.

[0041] The top cover 17 includes a transparent member 172 , and part or all of the transparent member 172 is located directly above the clean water tank 131 , so that the user can intuitively observe the flow of clean water in the clean water tank 131 , thereby improving the user's visual experience.

[0042] Please refer to Figure 2 As shown, the sewage component 14 includes a sewage trough portion 141, a water receiving plate 142 and a connecting portion 143. The various components of the sewage component 14 can be integrally injection molded. The sewage trough 1411 is arranged on the sewage trough portion 141. The sewage trough portion 141 is fixedly connected to the side wall of the main body 11, such as welding, etc., or the sewage trough portion 141 and the main body 11 are integrally injection molded to reduce the production process and reduce costs.

[0043] One end of the water receiving plate 142 is fixedly connected to the sewage trough portion 141 to increase the structural strength of the two and improve the stability of the sewage trough portion 141. The sewage trough portion 141 is located below the water receiving plate 142. Under the action of the wiper strip 18, the sewage on the drum 12 can flow into the sewage trough 1411 through the water receiving plate 142 by its own gravity. The sewage is collected quickly and easily, reducing the possibility of sewage turbulence. The other end of the water receiving plate 142 is close to the wiper strip 18, so that the sewage can directly enter the water receiving plate 142 after being separated from the surface of the drum 12, thereby reducing the accumulation of sewage on the surface of the drum 12 and the possibility of sewage flowing out along the gaps between the components. At the same time, the water receiving plate 142 is close to the surface of the drum 12, and the distance between the water receiving plate 142 and the surface of the drum 12 is between 2 mm, but the water receiving plate 142 and the surface of the drum 12 do not contact each other, so that the water receiving plate 142 will neither interfere with the drum 12 to cause sewage to flow out from under the water receiving plate 142, nor cause sewage to flow out from the gap between the water receiving plate 142 and the surface of the drum 12, thereby reducing the possibility of sewage leakage and improving user experience.

[0044] One end of the connecting portion 143 is connected to the sewage trough portion 141, which improves the stability of the sewage trough portion 141 and enhances the structural strength. The other end of the connecting portion 143 is connected to the top cover 17 for supporting the top cover 17 and improving the structural strength of the top cover 17. At the same time, the top cover 17, the connecting portion 143, the sewage trough portion 141, the water receiving plate 142 and the wiper strip 18 together form a cavity. Even if the cleaning tool encounters an uneven surface or changes direction due to external force, the sewage is only in the above-mentioned cavity, which reduces the possibility of leakage to the outside and improves the user experience.

[0045] When the cleaning tool is working, the roller 12 rolls to move the cleaning tool forward, the roller 12 is located in front of the sewage component 14, the wiper strip 18 is located between the water purification component 13 and the sewage component 14, and the wiper strip 18 is located above the roller 12. The wiper strip 18 squeezes out the sewage on the roller 12 by interfering with the roller 12, and the sewage flows to the sewage tank 1411 through the water receiving plate 142, reducing the possibility of sewage splashing and leakage, and improving the cleaning performance. During the operation of the cleaning tool, the clean water tank 131 first wets the roller 12, the roller 12 contacts the surface to be cleaned, and is used to clean the surface, and then the sewage on the roller 12 is cleaned by the wiper strip 18, and this cycle is used for cleaning.

[0046] Please refer to Figure 8As shown, the top cover 17 includes a protrusion 173, and the top cover 17 is rotatably connected to the body 11. The top cover 17 can be rotated until the protrusion 173 interferes with the drum 12, and the interference depth is between 1mm and 5mm. The interference depth can be adjusted by the rotation angle of the top cover 17. After the top cover 17 is turned over, the drum 12 can be rinsed with external water. The erected top cover 17 can reduce the impact of the washing water on the cleaning head 1, thereby improving the convenience of cleaning the drum 12. At the same time, during the cleaning process, the drum 12 can be deeply cleaned, and the top cover 17 can scrape off the stains on the surface of the drum 12 to improve the cleaning effect.

[0047] In some embodiments, the clean water tank 131 is located above the sewage tank 1411, so that there is a height difference between the clean water in the clean water tank 131 and the sewage in the sewage tank 1411. When the clean water enters the sewage tank 1411 through the first connecting tank 15, the gravitational potential energy can be converted into kinetic energy, thereby improving the impact performance of the clean water. Moreover, the clean water tank 131 is higher than the sewage tank 1411, and the sewage in the sewage tank 1411 will not contaminate the clean water in the clean water tank 131, thereby improving the cleaning performance of the cleaning tools.

[0048] In some embodiments, the second retaining rib 133 and the wiper strip 18 may be the same component, so that the structure of the cleaning tool is simpler.
