Description

Technical Field

[0001] The present disclosure relates to the technical field of cleaning equipment, and in particular to a water squeezing mechanism, a cleaning head and a cleaning tool. Background Art

[0002] The existing integrated mopping and sweeping cleaning tools are implemented by using a water-dust flow path, that is, the wet cleaning roller is rolled on the cleaning surface to adsorb dust to the surface of the cleaning roller, and at the same time, the surface of the cleaning roller is partially cleaned with clean water, and then the cleaning part of the cleaning roller is squeezed by the water squeezing structure to discharge the water, so as to avoid the cleaning roller carrying too much water, resulting in too much water on the cleaning surface. At the same time, during the cleaning process or the clean water flushing process, some dust enters the shallow layer of the cleaning roller, which cannot be cleaned by flushing. The surface of the cleaning roller that squeezes the cleaning part can take away the shallow dust that enters the cleaning roller, thereby achieving continuous cleaning. However, the existing squeezing mechanism cannot effectively clean the sticky garbage deposits, which affects the use. Summary of the invention

[0035] The present invention discloses a water squeezing mechanism, a cleaning head and a cleaning tool.

[0051] The preferred embodiments of the present invention will be described below in conjunction with the accompanying drawings.

[0052] The technical solution of the present invention will be described in detail below in conjunction with the accompanying drawings.

[0053] Figures 1 - 6 As shown, the present invention provides an embodiment of a water squeezing mechanism for a combined sweeping and mopping cleaning head.

[0054] The water squeezing mechanism of the combined sweeping and mopping cleaning head includes a water squeezing strip 41 that deforms the surface of the cleaning roller 2, and at least one side of the water squeezing strip 41 is on the same straight line as the radius of the cleaning roller 2.

[0055] Specifically, a fixing frame 4 is provided at the end of the water squeezing strip 41 away from the water pressing end, and the fixing frame 4 is connected to the cleaning head bracket 1. After assembly, the fixing frame 4 forms a water squeezing groove between the water squeezing strip 41 thereon and the surface of the cleaning roller 2. The water-facing surface or another side surface of the water squeezing strip 41 is on the same straight line as the radius of the cleaning roller 2, that is, the included angle a between the fixing frame 4 and one side surface of the water squeezing strip 41 is 90 degrees.

[0056] During use, the water squeezing strip forms a groove A distributed axially on the surface of the cleaning roller. During the rotation of the cleaning roller, the water adsorbed on the surface of the cleaning area and inside the cleaning roller can be squeezed out, avoiding the residue of a large amount of liquid in the cleaning area and causing water stains to form on the cleaning surface. At the same time, due to the special structure of the water squeezing strip 41, it is easier to clean the sticky garbage that may adhere to the surface 21 of the cleaning roller 2, avoiding the deposition of sticky garbage on the cleaning roller and increasing the resistance of the cleaning roller during cleaning.

[0057] Strip-shaped cleaning grooves (not marked in the attached drawing) are uniformly arranged axially on the surface of the cleaning roller 2. The existence of these cleaning grooves can produce a better cleaning effect, but at the same time, it is easy to attach garbage and form a deposition phenomenon of sticky garbage.

[0058] In order to reduce the rolling friction between the water squeezing strip 41 and the surface of the cleaning roller 2, the resistance generated by the water squeezing on the cleaning roller can be reduced. A cleaning structure 5 for cleaning the attachments on the surface of the cleaning roller is provided on the water-facing surface of the water squeezing strip 41. The cleaning structure 5 is located in the surface mutation area of the cleaning roller 2, that is, between the edge of the groove A formed by the water squeezing of the surface 21 of the cleaning roller 2 and the water squeezing strip 41. The cleaning structure 5 includes a plurality of protrusions distributed along the length direction of the water squeezing strip 41, and there are gaps between adjacent protrusions (not marked in the attached drawing). The protrusions can be set as triangular or similar triangular structures. Two sides of the protrusions form two included angles with the water-facing surface of the water squeezing strip 41, and an acute angle is formed between the upper end surface of the protrusion and the upper surface of the water-facing surface. Due to the cleaning structure near the water squeezing strip 41, the water squeezing strip 41 causes the surface shape of the cleaning roller 2 to mutate, so that the attachments adhering to the surface 21 of the cleaning roller 2, especially those in the form of lines such as hair or some sticky garbage, are partially separated from the cleaning roller. And the cleaning structure is exactly in the surface mutation area, so it is very easy to clean the attachments from the surface 21 of the cleaning roller 2. The protrusions are exactly located in the mutation area when set and do not come into contact with the surface of the cleaning roller. In this way, the attachments can be cleaned without affecting the surface of the cleaning roller and prolonging the service life. According to needs, the cross-section of the cleaning groove in the vertical direction of the length is square, V-shaped, wavy, etc.

[0059] The present invention also provides a combined sweeping and mopping cleaning head, which includes a cleaning head body 1, a cleaning roller 2 rotatably connected to the cleaning body, and a garbage box 3 for collecting the garbage cleaned by the cleaning roller. The combined sweeping and mopping cleaning head is also provided with a water squeezing mechanism, which includes a water squeezing strip 41 that deforms the surface of the cleaning roller 2, and at least one side surface of the water squeezing strip 41 is on the same straight line as the radius of the cleaning roller 4.

[0060] Specifically, a fixing frame 4 is provided at a position of the water squeezing strip 41 away from the water pressing end. The fixing frame 4 is connected to the cleaning head bracket 1. After assembly, the fixing frame 4 forms a water squeezing groove with the water squeezing strip 41 on its surface and the surface of the cleaning roller 4. The water-facing surface or another side surface of the water squeezing strip 41 is on the same straight line as the radius of the cleaning roller 2, that is, the included angle a between the fixing frame 4 and one side surface of the water squeezing strip 41 is 90 degrees.

[0061] During use, the water squeezing strip forms an axially distributed groove on the surface of the cleaning roller. During the rotation of the cleaning roller, the water that may be adsorbed on the surface of the cleaning area and inside the cleaning roller can be squeezed out, avoiding the residue of a large amount of liquid in the cleaning area and causing water stains on the cleaning surface during cleaning. At the same time, due to the special structure of the water squeezing strip 41, it is easier to clean the sticky garbage that may adhere to the surface of the cleaning roller 2, avoiding the deposition of sticky garbage on the cleaning roller and increasing the resistance of the cleaning roller during cleaning.

[0062] Bar-shaped cleaning grooves (not marked in the attached drawing) are uniformly arranged along the axis on the surface of the cleaning roller 2. The existence of these cleaning grooves can produce a better cleaning effect, but at the same time, it is easy to adhere to garbage and form a deposition phenomenon of sticky garbage.

[0063] In order to reduce the rolling friction between the water squeezing strip 41 and the surface of the cleaning roller 2 and reduce the resistance generated by water squeezing on the cleaning roller. A cleaning structure 5 for cleaning the attachments on the surface of the cleaning roller is provided on the water-facing surface of the water squeezing strip 41. The cleaning structure 5 is located in the surface mutation area of the cleaning roller 2, that is, between the surface 21 of the cleaning roller 2 and the edge of the water squeezing groove A formed by the water squeezing of the water squeezing strip 41. The cleaning structure 5 includes a plurality of protrusions distributed along the length direction of the water squeezing strip 41, and gaps are provided between adjacent protrusions (not marked in the attached drawing). The protrusions can be set as triangular or similar triangular structures. Two sides of the protrusions form two included angles with the water-facing surface of the water squeezing strip 41, and an acute angle is formed between the upper end surface of the protrusion and the upper surface of the water-facing surface. Due to the cleaning structure near the water squeezing strip 41, the water squeezing strip 41 causes the surface shape of the cleaning roller 2 to mutate, so that the attachments adhering to the surface 21 of the cleaning roller 2, especially those in the form of lines such as hair or sticky garbage with a certain degree, are partially separated from the cleaning roller. And the cleaning structure is exactly in the surface mutation area, so that the attachments can be easily cleaned from the surface 21 of the cleaning roller 2. The protrusions are set to be exactly in the mutation area and do not come into contact with the surface of the cleaning roller. In this way, the attachments can be cleaned without affecting the surface of the cleaning roller and prolonging the service life. As required, the cross-section of the cleaning groove along the length vertical direction is square, V-shaped, wavy, etc.

[0064] The present invention also provides a combined sweeping and mopping cleaning tool, which includes a cleaning head and a handle movably connected to the cleaning head. The cleaning head includes a cleaning head body, a cleaning roller rotatably connected to the cleaning body, and a dustbin for collecting the garbage cleaned by the cleaning roller. The combined sweeping and mopping cleaning head is also provided with a water squeezing mechanism, which includes a water squeezing strip 41 that deforms the surface of the cleaning roller 2, and at least one side of the water squeezing strip 41 is on the same straight line as the radius of the cleaning roller 2.

[0065] Specifically, a fixing frame 4 is provided at the end of the water squeezing strip 41 away from the water pressing end. The fixing frame 4 is connected to the cleaning head bracket 1. After assembly, the fixing frame 4 forms a water squeezing groove on the surface of the cleaning roller 2 with the water squeezing strip 41 thereon. The water-facing surface or another side surface of the water squeezing strip 41 is on the same straight line as the radius of the cleaning roller 2, that is, the included angle a between the fixing frame 4 and one side surface of the water squeezing strip 41 is 90 degrees.

[0066] During use, the water squeezing strip forms an axially distributed groove on the surface of the cleaning roller. During the rotation of the cleaning roller, the water that may be adsorbed on the surface of the cleaning area and inside the cleaning roller can be squeezed out, avoiding the residue of a large amount of liquid in the cleaning area and causing water stains on the cleaning surface. At the same time, due to the special structure of the water squeezing strip 41, it is easier to clean the sticky garbage that may adhere to the surface of the cleaning roller 2, avoiding the deposition of sticky garbage on the cleaning roller and increasing the resistance of the cleaning roller during cleaning.

[0067] Bar-shaped cleaning grooves (not marked in the drawings) are uniformly arranged along the axis on the surface of the cleaning roller 2. The existence of these cleaning grooves can produce a better cleaning effect, but it is also easy to attach garbage, and at the same time, it is easy to form a deposition phenomenon of sticky garbage.

[0068] In order to reduce the rolling friction between the water squeezing bar 41 and the surface of the cleaning roller 2, the resistance of the squeezing water to the cleaning roller can be reduced. The water-facing surface of the water squeezing bar 41 is provided with a cleaning structure 5 for cleaning the attachments on the surface of the cleaning roller. The cleaning structure 5 is located in the sudden change area of ​​the surface of the cleaning roller 2, that is, between the surface 21 of the cleaning roller 2 and the edge of the pressure groove A formed by squeezing water from the water squeezing bar 41. The cleaning structure 5 includes a plurality of protrusions distributed along the length direction of the water squeezing bar 41, and there is a gap between adjacent protrusions (not shown in the drawings). The protrusion can be set as a triangle or a similar triangle structure, and the two sides of the protrusion form two angles with the water-facing surface of the water squeezing bar 41, wherein the upper end surface of the protrusion forms an acute angle with a side of the upper part of the water-facing surface. By providing a cleaning structure near the squeezing strip 41, the squeezing strip 41 causes a sudden change in the shape of the surface of the cleaning roller 2, so that the attachments attached to the surface 21 of the cleaning roller 2, especially the linear shape such as hair, or the local part of the sticky garbage, are separated from the cleaning roller 2, and the cleaning structure is just in the sudden change area of ​​the surface, so that the attachments can be easily cleaned off the surface 21 of the cleaning roller 2. The protrusion is exactly located in the sudden change area when it is set, and does not contact the surface of the cleaning roller. In this way, the attachments can be cleaned without affecting the surface of the cleaning roller, thereby extending the service life. According to needs, the cross section of the cleaning groove along the vertical direction of the length is square, V-shaped, or wavy, etc.

[0069] The embodiments of the present application are described in detail above. Specific examples are used herein to illustrate the principles and implementation methods of the present application. The description of the above embodiments is only used to help understand the method and its core idea of ​​the present application. At the same time, changes or deformations made by those skilled in the art based on the ideas of the present application, the specific implementation methods and the scope of application of the present application, all belong to the scope of protection of the present application. In summary, the content of this specification should not be construed as a limitation on the present application.
