Description

[0001] This application is a divisional application of Chinese Patent Application No. 202210524715.1 entitled "An efficient stain removal and cleaning mechanism and cleaning appliance", the contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of cleaning equipment technology, and more particularly to a high-efficiency stain removal and cleaning mechanism. Background Technology

[0003] Early floor cleaning tools used by people included brooms, mops, and floor scrubbers, which relied primarily on manual operation. As technology advanced, people's demands for floor cleaning tools gradually increased, leading to the emergence of vacuum cleaners. These vacuum cleaners, powered by electricity, use negative pressure to suck up debris and dust from the floor. Classified by cleaning methods and the flow paths of small and large particles of debris, this type of technology is typically categorized as airflow technology.

[0004] Chinese patent document CN100581433B discloses a floor cleaner combined with a floor mopping device that has a sweeping function. It includes a housing, a floor mopping device mounted at the front end of the housing, a cleaning device for cleaning the floor mopping device, and a transmission device. The floor mopping device includes a rotating shaft and a wiping layer covering the rotating shaft. The cleaning device forms a cleaning chamber containing cleaning liquid on the surface of the wiping layer and in a direction parallel to the axial direction of the rotating shaft. The transmission device drives the rotating shaft to rotate. The cleaning chamber has an inlet connected to a clean water container and an outlet connected to a wastewater container. The transmission device further includes a water pump that injects cleaning liquid from the clean water container into the cleaning chamber. A waste collection device is located immediately following the rotating shaft of the floor mopping device. The waste collection device includes a guide surface that is close to the ground and near the wiping layer of the floor mopping device. The rotating wiping layer of the floor mopping device uses friction to drive waste along the guide surface into the waste collection device. Although this solution can achieve water and dust cleaning, the formation of a cleaning chamber in the decontamination device causes the clean water used for cleaning to mix with the squeezed-out wastewater and the surface of the roller, resulting in the roller surface not being cleaned thoroughly. Some debris is carried to the surface being cleaned, resulting in low cleaning efficiency. Summary of the Invention

[0011] In one or more alternative embodiments, the pre-compression structure includes a plurality of pre-compression blocks distributed in a straight line, with gaps between each pre-compression block for the discharge of wastewater squeezed out by the dewatering strip.

[0012] In one or more alternative embodiments, the depth of the first interference groove is greater than the depth of the second interference groove.

[0013] In one or more alternative embodiments, the second interference groove is located within the first interference groove or on the surface of the non-interfering cleaning roller.

[0024] In one or more alternative embodiments, the cleaning appliance further includes a handle connected to the housing, rollers mounted on the housing, control circuitry, a clean water supply mechanism, and a wastewater collection mechanism.

[0025] In one or more alternative embodiments, the clean water supply mechanism includes a clean water tank and a water supply pipeline connecting the clean water tank and the spray nozzle, as well as a water pump that provides power to the clean water.

[0027] This invention provides a high-efficiency stain removal and cleaning mechanism and cleaning tool. The high-efficiency stain removal and cleaning mechanism includes a cleaning roller and a squeezing strip that creates a first interference groove on the surface of the cleaning roller. The squeezing strip has multiple spray nozzles, each of which is no higher than the opening of the first interference groove. In use, the cleaning roller rotates, and clean water is sprayed at high pressure through the spray nozzles from a clean water supply pipeline, acting on the surface of the cleaning roller. When the surface of the cleaning roller is squeezed, the liquid inside the cleaning roller, such as water, carries out fine dust inside the cleaning roller. Under the dual action of the squeezed water and the clean water rinsing, on the one hand, fine particles that may be attached to the surface of the cleaning roller can be washed away from the cleaning roller, preventing fine particles from adhering to the rear end of the squeezing strip and causing odor; on the other hand, the cleaning roller is moistened, maintaining a certain level of cleanliness and humidity on the surface of the cleaning roller. At the same time, it has a better cleaning effect on slender objects attached to the surface of the cleaning roller. Attached Figure Description

[0042] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0043] The following will describe the scheme of this application in detail with reference to the accompanying drawings.

[0044] like Figure 1-4 As shown, the present invention provides an embodiment of a high-efficiency stain removal and cleaning mechanism.

[0045] The high-efficiency cleaning mechanism includes a cleaning roller 2 and a squeezing strip 3 that creates a first interference groove 4 on the surface of the cleaning roller 2. The squeezing strip 3 is provided with a plurality of spray nozzles 33, each of which is not higher than the opening of the first interference groove 4.

[0046] Specifically, the cleaning mechanism includes a housing 1 for mounting a cleaning roller 2 and a wringer 3, the cleaning roller 2 being driven by a motor (not shown in the drawings). After assembly, the wringer 3 exerts pressure interference on a portion of the surface of the cleaning roller 2, creating a first interference groove 4 on the surface of the cleaning roller 2. The wringer 3 is typically arranged parallel to the axis of rotation of the cleaning roller 2; therefore, the first interference groove 4 formed on the surface of the cleaning roller 2 is parallel to the axis of rotation of the cleaning roller 2. The wringer 3 includes a wringing section 30 and a clean water pipe 31 disposed in the wringing section 30, the clean water pipe being connected to each spray nozzle 33. The horizontal spraying range of each spray nozzle 33 is greater than the width of the spray nozzle 33 itself.

[0047] The water nozzle 33 is located in front of the direction of rotation of the cleaning roller 2 during operation, that is, the water spraying direction of the water nozzle 33 is opposite to the direction of rotation of the cleaning roller 2.

[0048] The water spraying area of ​​the nozzle 33 includes at least the area where the first interference pressure groove 4 intersects with the surface E of the non-interference cleaning roller, i.e., area C in the figure. Since the water spraying area of ​​the nozzle 33 is located in the area where the first interference pressure groove 4 intersects with the surface E of the non-interference cleaning roller, a large area of ​​pressure can be formed when the surface of the cleaning roller is squeezed. This results in a large squeezing force on the liquid inside the cleaning roller, and the liquid is squeezed out from the front side of the first interference pressure groove 4 at a large pressure. A large and rapid water flow can be formed in the area where the first interference pressure groove 4 intersects with the surface E of the non-interference cleaning roller. The water flow generated by this squeezing is much smaller than the water flow velocity sprayed from the nozzle 33. By superimposing a large rinsing water flow velocity at this point, on the one hand, the particles carried out can be washed away from the first interference pressure groove 4, preventing fine particles from adhering to the rear end of the squeezing strip and causing odor. On the other hand, the surface of the cleaning roller in the rinsing area is kept in a clean water state, thereby maintaining a certain level of cleanliness and humidity on the surface of the cleaning roller.

[0049] To achieve a more effective cleaning of slender objects adhering to the surface of the cleaning roller 2, the squeezing strip 3 is further equipped with a pre-pressing structure 34 that generates multiple second interference grooves 5 on the surface of the cleaning roller 2. The spray nozzle 33 is located on the pre-pressing structure 34. The pre-pressing structure 34 includes multiple pre-pressing blocks (not shown in the attached diagram) distributed in a straight line, with gaps (not shown in the attached diagram) between each pre-pressing block for the wastewater squeezed out by the squeezing strip 3 to be discharged. Since the pre-pressing blocks generate multiple second interference grooves 5 on the surface of the cleaning roller 2, each second interference groove 5 having a depth of b, and since the second interference grooves 5 are formed by multiple pre-pressing blocks and are discontinuous, when slender debris adheres to the surface of the cleaning roller 2, the presence of multiple second interference grooves 5 causes some of the debris to separate from the surface of the cleaning roller 2 at the second interference grooves 5. At this point, with appropriate placement of the spray nozzle 33, the slender debris can be easily separated from the surface of the cleaning roller 2, thereby improving the cleaning effect.

[0050] The second interference groove 5 is located within the first interference groove 4 or on the surface C of the cleaning roller without interference. It can automatically peel some of the slender debris off the surface of the cleaning roller 2 by utilizing the sewage extrusion effect generated during squeezing. The purpose of setting the second interference groove 5 is to separate the slender debris attached to the surface of the cleaning roller 2 from the cleaning roller, making it easier to clean the slender debris attached to the surface of the cleaning roller 2.

[0051] As needed, the depth 'a' of the first interference groove 4 is greater than the depth 'b' of the second interference groove 5. This avoids generating excessive resistance during the operation of the cleaning roller 2, thus preventing increased noise and energy consumption.

[0052] The present invention also provides an embodiment of a cleaning appliance.

[0053] The cleaning device includes a cleaning mechanism, which includes a cleaning roller 2 and a squeezing strip 3 that creates a first interference groove 4 on the surface of the cleaning roller 2. The squeezing strip 3 is provided with a plurality of spray nozzles 33, each of which is not higher than the opening of the first interference groove 4.

[0054] Specifically, the cleaning appliance includes a handle connected to the housing, rollers mounted on the housing, a control circuit, a clean water supply mechanism, and a wastewater collection mechanism. The clean water supply mechanism includes a clean water tank and a water supply pipe connecting the clean water tank to the spray nozzle 33, as well as a water pump powering the clean water. The wastewater collection mechanism includes a wastewater tank and a wastewater pipe connecting the wastewater tank to the wastewater outlet, as well as a wastewater pump powering the wastewater.

[0055] The cleaning mechanism includes a housing 1 for mounting a cleaning roller 2 and a wringer 3, the cleaning roller 2 being driven by a motor (not shown in the drawings). After assembly, the wringer 3 exerts pressure interference on a portion of the surface of the cleaning roller 2, creating a first interference groove 4 on the surface of the cleaning roller 2. The wringer 3 is typically arranged parallel to the axis of rotation of the cleaning roller 2; therefore, the first interference groove 4 formed on the surface of the cleaning roller 2 is parallel to the axis of rotation of the cleaning roller 2. The wringer 3 includes a wringing section 30 and a clean water pipe 31 disposed in the wringing section 30, the clean water pipe being connected to each spray nozzle 33. The horizontal spraying range of each spray nozzle 33 is greater than the width of the spray nozzle 33 itself.

[0056] The water nozzle 33 is located in front of the direction of rotation of the cleaning roller 2 during operation, that is, the water spraying direction of the water nozzle 33 is opposite to the direction of rotation of the cleaning roller 2.

[0057] The water spraying area of ​​the nozzle 33 includes at least the area where the first interference pressure groove 4 intersects with the surface E of the non-interference cleaning roller, i.e., area C in the figure. Since the water spraying area of ​​the nozzle 33 is located in the area where the first interference pressure groove 4 intersects with the surface E of the non-interference cleaning roller, a large area of ​​pressure can be formed when the surface of the cleaning roller is squeezed. This results in a large squeezing force on the liquid inside the cleaning roller, and the liquid is squeezed out from the front side of the first interference pressure groove 4 at a large pressure. A large and rapid water flow can be formed in the area where the first interference pressure groove 4 intersects with the surface E of the non-interference cleaning roller. The water flow generated by this squeezing is much smaller than the water flow velocity sprayed from the nozzle 33. By superimposing a large rinsing water flow velocity at this point, on the one hand, the particles carried out can be washed away from the first interference pressure groove 4, preventing fine particles from adhering to the rear end of the squeezing strip and causing odor. On the other hand, the surface of the cleaning roller in the rinsing area is kept in a clean water state, thereby maintaining a certain level of cleanliness and humidity on the surface of the cleaning roller.

[0058] To achieve a more effective cleaning of slender objects adhering to the surface of the cleaning roller 2, the squeezing strip 3 is further equipped with a pre-pressing structure 34 that generates multiple second interference grooves 5 on the surface of the cleaning roller 2. The spray nozzle 33 is located on the pre-pressing structure 34. The pre-pressing structure 34 includes multiple pre-pressing blocks (not shown in the attached diagram) distributed in a straight line, with gaps (not shown in the attached diagram) between each pre-pressing block for the wastewater squeezed out by the squeezing strip 3 to be discharged. Since the pre-pressing blocks generate multiple second interference grooves 5 on the surface of the cleaning roller 2, each second interference groove 5 having a depth of b, and since the second interference grooves 5 are formed by multiple pre-pressing blocks and are discontinuous, when slender debris adheres to the surface of the cleaning roller 2, the presence of multiple second interference grooves 5 causes some of the debris to separate from the surface of the cleaning roller 2 at the second interference grooves 5. At this point, with appropriate placement of the spray nozzle 33, the slender debris can be easily separated from the surface of the cleaning roller 2, thereby improving the cleaning effect.

[0059] The second interference groove 5 is located within the first interference groove 4 or on the surface C of the cleaning roller without interference. It can automatically peel some of the slender debris off the surface of the cleaning roller 2 by utilizing the sewage extrusion effect generated during squeezing. The purpose of setting the second interference groove 5 is to separate the slender debris attached to the surface of the cleaning roller 2 from the cleaning roller, making it easier to clean the slender debris attached to the surface of the cleaning roller 2.

[0060] As needed, the depth 'a' of the first interference groove 4 is greater than the depth 'b' of the second interference groove 5. This avoids generating excessive resistance during the operation of the cleaning roller 2, thus preventing increased noise and energy consumption.

[0061] The above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions or combinations can be made to some structures (technical features) in one or more embodiments. Such modifications or substitutions or combinations do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the various embodiments of the present invention, unless the possibility of substituting or combining structures (technical features) in different embodiments is explicitly excluded in the embodiments, or such substitutions or combinations are contrary to the overall concept of the invention.
