Meanwhile, the elongated objects adhered to the surface of the cleaning roller can be better cleaned.

Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of cleaning equipment, in particular to a high-efficiency decontamination cleaning mechanism and a cleaning appliance. BACKGROUND

[0002] The early ground cleaning tools used by people are brooms, mops, floor wipes, etc., which mainly rely on manual operation to complete the cleaning work. With the progress of science and technology, people's requirements for ground cleaning tools have gradually increased. First appeared is the dust collector, which relies on electric power to generate negative pressure to suck up garbage, dust, etc. on the ground. From the cleaning means and the flow path of small and large particle garbage, this kind of technology is usually classified as air dust circulation technology.

[0003] Chinese patent document CN100581433B discloses a ground cleaner combined with a floor wiping device having a sweeping function, which comprises a housing, a floor wiping device mounted at the front end of the housing, a decontamination device for washing the floor wiping device, and a transmission device. The floor wiping device comprises a rotating shaft and a wiping layer wrapped around the rotating shaft. The decontamination device forms a cleaning cavity containing cleaning liquid on the surface of the wiping layer and parallel to the axial direction of the rotating shaft. The transmission device drives the rotating shaft to rotate. Its feature is that the inlet of the cleaning cavity is connected to a clean water container, and the outlet is connected to a sewage container. The transmission device further comprises a water pump that injects cleaning liquid from the clean water container into the cleaning cavity. A garbage collection device is arranged next to the rotating shaft of the floor wiping device.

[0036] The preferred embodiments of the present application are described below in conjunction with the accompanying drawings, and it should be understood that the preferred embodiments described herein are only used to illustrate and explain the present application, and are not intended to limit the present application.

[0037] The scheme of the present application will be described in detail below in conjunction with the accompanying drawings.

[0038] As Figures 1-4 shown, the present application provides an embodiment of a high-efficiency stain removal cleaning mechanism.

[0039] The high-efficiency stain removal cleaning mechanism comprises a cleaning roller 2 and a water squeezing strip 3 generating a first interference pressure groove 4 on the surface of the cleaning roller 2. The water squeezing strip 3 is provided with a plurality of water spraying openings 33, and each water spraying opening 33 is not higher than the notch of the first interference pressure groove 4.

[0040] Specifically, the cleaning mechanism comprises a housing 1 for mounting the cleaning roller 2 and the water squeezing strip 3, and the cleaning roller 2 is driven by a motor (not shown in the drawing). After assembly, the water squeezing strip 3 exerts extrusion interference on the surface of the cleaning roller 2 in a partial area, and generates a first interference pressure groove 4 on the surface of the cleaning roller 2. The water squeezing strip 3 is usually arranged in parallel along the rotation axis of the cleaning roller 2, so that the first interference pressure groove 4 formed on the surface of the cleaning roller 2 is parallel to the rotation axis of the cleaning roller 2. The water squeezing strip 3 comprises a water squeezing part 30 and a clean water pipeline 31 arranged on the water squeezing part 30, and the clean water pipeline 31 is in communication with each water spraying opening 33, respectively. The horizontal spraying range of each water spraying opening 33 is greater than the width of the water spraying opening 33 itself.

[0041] The water jet 33 is located at the front side of the cleaning roller 2 in the direction of rotation during operation, i.e. the water jet direction of the water jet 33 is opposite to the direction of rotation of the cleaning roller 2.

[0042] The water jet area of the water jet 33 at least includes the intersection area of the first interference pressure groove 4 and the non-interference cleaning roller surface E, i.e. the area C in the figure. Since the water jet area of the water jet 33 is located at the intersection area of the first interference pressure groove 4 and the non-interference cleaning roller surface E, a larger extrusion stress area can be formed when the cleaning roller surface is extruded, so that the liquid in the cleaning roller is extruded with a larger force, and the liquid is extruded from the front side of the first interference pressure groove 4 with a larger pressure, and a larger and more rapid water flow can be formed at the intersection area of the first interference pressure groove 4 and the non-interference cleaning roller surface E. The extrusion water flow is far smaller than the water flow speed of the water jet 33, and by superimposing a larger flushing water flow speed at this position, on the one hand, the particles carried out can be flushed away from the first interference pressure groove 4, so as to avoid that the fine particles adhere to the rear end of the water extrusion strip and cause odor generation, and on the other hand, the cleaning roller surface in the flushed area can be kept in a clean water state, so as to keep the cleaning roller surface in a certain cleaning humidity.

[0043] In order to more effectively clean the long objects attached to the surface of the cleaning roller, the water extrusion strip 3 is further provided with a pre-pressing structure 34 for generating a plurality of second interference pressure grooves 5 on the surface of the cleaning roller 2. The water jet 33 is arranged on the pre-pressing structure 34. The pre-pressing structure 34 includes a plurality of pre-pressing blocks (not marked in the figure) distributed on a straight line, and a gap (not marked in the figure) is arranged between each pre-pressing block for discharging the sewage extruded by the water extrusion strip 3. Since the pre-pressing blocks can generate a plurality of second interference pressure grooves 5 on the surface of the cleaning roller 2, the depth of each second interference pressure groove 5 is b. Since the second interference pressure grooves 5 are formed by a plurality of pre-pressing blocks, and each second interference pressure groove 5 is discontinuous, when the long garbage is attached to the surface of the cleaning roller 2, the plurality of second interference pressure grooves 5 can separate part of the long garbage from the surface of the cleaning roller 2, and at this time, the long garbage can be easily separated from the surface of the cleaning roller 2 by appropriately setting the water jet 33, so as to improve the cleaning effect.

[0044] The second interference pressure groove 5 is located in the first interference pressure groove 4 or the non-interference cleaning roller surface C, and can automatically strip part of the long garbage from the surface of the cleaning roller 2 by the sewage extrusion effect during extrusion. The purpose of arranging the second interference pressure groove 5 is to separate the long garbage attached to the surface of the cleaning roller 2 from the cleaning roller, so that the long garbage attached to the surface of the cleaning roller 2 is more easily cleaned.

[0045] According to the need, the depth a of the first interference pressure groove 4 is greater than the depth b of the second interference pressure groove 5. In this way, the resistance generated during the operation of the cleaning roller 2 can be avoided, so as to increase the noise and energy consumption.

[0046] The present application also provides a cleaning appliance.

[0047] The cleaning appliance comprises a cleaning mechanism, which comprises a cleaning roller 2 and a water squeezing strip 3 for forming a first interference groove 4 on the surface of the cleaning roller 2, wherein the water squeezing strip 3 is provided with a plurality of water spraying openings 33, and each water spraying opening 33 is not higher than the opening of the first interference groove 4.

[0048] In particular, the cleaning appliance comprises a handle connected with the shell, a roller wheel mounted on the shell, a control circuit, a clean water supply mechanism and a sewage collection mechanism, wherein the clean water supply mechanism comprises a clean water tank, a water supply pipeline connected with the clean water tank and the water spraying openings 33, and a water pump for providing power to the clean water. The sewage collection mechanism comprises a sewage tank, a sewage pipeline connected with the sewage tank and a sewage outlet, and a sewage pump for providing power to the sewage.

[0049] The cleaning mechanism comprises a shell 1 for mounting the cleaning roller 2 and the water squeezing strip 3, and the cleaning roller 2 is driven by a motor (not shown in the figure). After assembly, the water squeezing strip 3 exerts extrusion interference on the surface of the cleaning roller 2 in a partial area, and forms a first interference groove 4 on the surface of the cleaning roller 2. The water squeezing strip 3 is usually arranged in parallel along the rotation axis of the cleaning roller 2, so that the first interference groove 4 formed on the surface of the cleaning roller 2 is parallel to the rotation axis of the cleaning roller 2. The water squeezing strip 3 comprises a water squeezing part 30 and a clean water pipeline 31 arranged on the water squeezing part 30, and the clean water pipeline 31 is respectively connected with each water spraying opening 33. The horizontal spraying range of each water spraying opening 33 is greater than the width of the water spraying opening 33 itself.

[0050] The water spraying openings 33 are located on the front side of the cleaning roller 2 in the rotation direction during operation, i.e. the water spraying direction of the water spraying openings 33 is opposite to the rotation direction of the cleaning roller 2.

[0051] The water spraying area of the water spraying openings 33 at least comprises the intersection area of the first interference groove 4 and the non-interference cleaning roller surface E, i.e. the area C in the figure. Since the water spraying area of the water spraying openings 33 is located in the intersection area of the first interference groove 4 and the non-interference cleaning roller surface E, a larger extrusion stress area can be formed when the cleaning roller surface is extruded, so that the liquid in the cleaning roller is extruded with a larger force, and the liquid is extruded from the front side of the first interference groove 4 with a larger pressure, and a larger and more rapid water flow can be formed in the intersection area of the first interference groove 4 and the non-interference cleaning roller surface E. The extrusion water flow is far smaller than the water flow speed of the water spraying openings 33. By superimposing a larger flushing water flow speed at this position, on one hand, the particles carried out can be flushed away from the first interference groove 4, so as to avoid that the fine particles adhere to the rear end of the water squeezing strip and cause odor generation, and on the other hand, the cleaning roller surface in the flushed area can be kept in a clean water state, so as to keep a certain cleaning humidity of the cleaning roller surface.

[0052] In order to clean the elongated objects attached to the surface of the cleaning roller more effectively, the water squeezing strip 3 is further provided with a pre-pressing structure 34 for forming a plurality of second interference pressure grooves 5 on the surface of the cleaning roller 2. The water spraying port 33 is arranged on the pre-pressing structure 34. The pre-pressing structure 34 comprises a plurality of pre-pressing blocks (not shown in the drawing) arranged in a straight line, and a gap (not shown in the drawing) is arranged between each pre-pressing block for discharging the sewage squeezed out by the water squeezing strip 3. Since the pre-pressing blocks can form a plurality of second interference pressure grooves 5 on the surface of the cleaning roller 2, the depth of each second interference pressure groove 5 is b, and since the second interference pressure grooves 5 are formed by a plurality of pre-pressing blocks and are discontinuous, when the elongated garbage is attached to the surface of the cleaning roller 2, the plurality of second interference pressure grooves 5 can separate part of the elongated garbage from the surface of the cleaning roller 2, and at this time, the elongated garbage can be easily separated from the surface of the cleaning roller 2 by appropriately setting the water spraying port 33, thereby improving the cleaning effect.

[0053] The second interference pressure grooves 5 are located in the first interference pressure grooves 4 or do not interfere with the surface C of the cleaning roller, and can automatically strip part of the elongated garbage from the surface of the cleaning roller 2 by the sewage squeezing effect during extrusion. The purpose of arranging the second interference pressure grooves 5 is to separate the elongated garbage attached to the surface of the cleaning roller 2 from the cleaning roller, so that the elongated garbage attached to the surface of the cleaning roller 2 is easier to clean.

[0054] According to the need, the depth a of the first interference pressure groove 4 is greater than the depth b of the second interference pressure groove 5. In this way, the greater resistance generated during the operation of the cleaning roller 2 can be avoided, thereby increasing the noise and energy consumption.

[0055] The above embodiments are only used to illustrate the technical solutions of the present application, but not to limit it; although the present application has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that they can still modify the technical solutions recorded in the foregoing embodiments, or equivalently replace, combine part of the structures (technical features) in one or more embodiments, and these modifications or replacements, combinations do not make the essence of the corresponding technical solutions deviate from the spirit and scope of the technical solutions of the embodiments of the present application, unless the embodiments explicitly exclude the possibility of replacing or combining the structures (technical features) in different embodiments, or this replacement or combination is contrary to the overall concept of the invention.
