Description

Technical Field

[0001] The present invention relates to the field of floor cleaning, and particularly to a cleaning machine. Background Art

[0002] Existing cleaning machines generally mainly set a roller to achieve the cleaning effect on the ground. The roller absorbs or adsorbs the waste liquid during the process of cleaning the ground, and clamps or adheres to the dirt, so as to drive and transfer the waste liquid and dirt formed during the process of cleaning the ground. Among them, a scraping structure is set for the roller, and the waste liquid and dirt on the roller are scraped and separated through the scraping structure. However, the existing scraping structure will form a relatively deep interference or pressing effect on the roller, and the scraping structure is in a structure of always deeply pressing the roller. In this way, it will cause problems that the roller will be deformed and unable to recover its shape after being deeply pressed by the scraping structure for a long time, and even problems of being easily damaged, resulting in a poor or ineffective effect of scraping the waste liquid and garbage, and further causing problems of secondary pollution to the ground and poor cleaning effect. At the same time, the functions of existing cleaning machines are relatively single, and they cannot provide users with a suitable roller structure according to different ground conditions, so they cannot better meet the cleaning needs of users for the ground, affecting the use experience effect of users on the cleaning machine.

[0047] Or, it is set that when the water absorption cylinder and the water drainage cylinder are respectively installed in place, they are configured to rotate and roll around the same rotation axis.

[0048] Compared with the prior art, the present invention has the following beneficial effects:

[0049] In this solution, the hydrophobic cylinder also realizes the cleaning of the ground. Among them, when the hydrophobic cylinder is not rotating and rolling, that is, when it is not cleaning the ground, a first concave part is formed. When it is rotating and rolling, that is, when it is cleaning the ground, a second concave part is formed. And it is set that the maximum depression depth of the formed first concave part is greater than the maximum depression depth of the second concave part. So that when the hydrophobic cylinder is not cleaning the ground, a shallow concave effect with a relatively small depression depth will be formed, and only when cleaning the ground will a deep concave effect with a relatively large depression depth be formed. This makes it so that no position on the outer surface of the hydrophobic cylinder will present a structural state of a long-term deep concave when the hydrophobic cylinder is not in use, effectively preventing problems such as deformation that cannot be restored and easy breakage due to the long-term deep concave structure on the outer surface of the hydrophobic cylinder, greatly improving the safety and reliability of the hydrophobic cylinder.

[0050] In this solution, the scraping part forms a contact and pressure-applying structure for the outer surface of the hydrophobic cylinder to correspond to the formation of the first concave part when the hydrophobic cylinder is not moving, and to correspond to the formation of the second concave part when the hydrophobic cylinder is moving. So that when the hydrophobic cylinder is not moving, that is, when it is not being used to clean the ground, a contact and pressure-applying structure that is deeply pressed by the scraping part will not be formed, effectively preventing problems such as deformation that cannot be restored and easy breakage due to the long-term deep pressure of the scraping part on the outer surface of the hydrophobic cylinder, greatly improving the safety and reliability of the hydrophobic cylinder.

[0051] In this solution, when the hydrophobic cylinder is not moving, that is, when it is not being used to clean the ground, a shallow pressure structure where it is constantly contacted and pressured by the scraping part is not likely to form a phenomenon of fatigue after contact pressure caused by the deep pressure of the scraping part on the hydrophobic cylinder, which is beneficial to maintaining the deformation effect of the outer surface of the hydrophobic cylinder to rebound and return to the initial shape, effectively preventing problems such as deformation fatigue or deformation failure on the outer surface of the hydrophobic cylinder.

[0052] In this solution, it is set that the hydrophobic cylinder can only form a structure deeply pressed by the scraping part, that is, form a second concave part with a greater depression depth, when it is rotating and rolling. When it is not rotating and rolling, it will not be deeply pressed by the scraping part but form a first concave part with a smaller depression depth. So that the scraping part can effectively form the second concave part to achieve a deep pressure effect when the hydrophobic cylinder contacts the ground for movement cleaning, thereby realizing the removal of the dirty liquid and garbage adhered to the outer surface of the hydrophobic cylinder, making the hydrophobic cylinder effectively maintain a clean state.

[0053] In this solution, the hydrophobic cylinder is set to a structure that can expand at least in the radial direction, so as to realize the expansion of the hydrophobic cylinder in the radial direction during rotational rolling motion, and realize that the hydrophobic cylinder is contacted by the scraping part and pressure is applied to form a second concave part. There is no need to set any power mechanism to provide power to make the scraping part form contact pressure on the hydrophobic cylinder. Instead, the centrifugal force formed by the rotational rolling motion of the hydrophobic cylinder itself is used to form a structural effect in which the outer surface of the hydrophobic cylinder can be deeply pressed by the scraping part, and when the hydrophobic cylinder is not moving, a structural effect in which the scraping part can perform shallow pressing is formed, making the overall structure simple, low-cost, and highly reliable, and effectively preventing the problem that the outer surface of the hydrophobic cylinder is continuously deeply pressed by the scraping part for a long time.

[0054] In this solution, the expansion structure of the hydrophobic cylinder in the radial direction is fully utilized to realize the structure in which it can be deeply pressed by the scraping part, and then the effect of the scraping part scraping off the sewage and garbage on the hydrophobic cylinder is realized, with a simple structure and high reliability.

[0055] In this solution, the expansion structure of the hydrophobic cylinder in the radial direction is fully utilized to realize a cleaning part with a concave structure formed after the outer surface of the hydrophobic cylinder effectively contacts the ground. Through the cleaning part, the effect of scraping the ground is effectively realized to scrape and collect the sewage and garbage on the ground, and the effect of driving and transferring the collection along the rotational rolling direction is realized.

[0056] In this solution, the structural setting and size setting of the hydrophobic cylinder enable it to effectively form a first concave part when not in rotational rolling motion, thereby forming the effect of being shallowly pressed by the scraping part, and effectively forming a second concave part when in rotational rolling motion, thereby forming the effect of being deeply pressed by the scraping part, improving the stability and reliability of the contact and pressing between the hydrophobic cylinder and the scraping part to scrape off sewage and dirt.

[0057] The area part of the hydrophobic cylinder in this solution other than the first concave part, the second concave part, and the cleaning part has an arc surface structure. Under the arc surface structure, the outer surface of the hydrophobic cylinder can be effectively scraped and cleaned, which can effectively improve the hydrophobic cylinder to maintain a clean and dry state and improve the effect of removing sewage and garbage from the hydrophobic cylinder.

[0058] The structural setting and size setting of the hydrophobic cylinder in this solution can enable the cleaning part to be effectively formed, thereby realizing the scraping and cleaning effect on the ground. At the same time, it can effectively form a rebound pushing and transferring effect on the driven sewage and garbage, improving the transferring effect of the sewage and garbage and the effectiveness of the hydrophobic cylinder in maintaining a clean state.

[0059] In this solution, the structures and dimensions of the outer cylinder part and the spacer part are set such that the hydrophobic cylinder can be effectively deformed and expanded, thereby effectively increasing the depression depth of the second recess relative to the first recess, and effectively enabling the scraping part to scrape off the sewage and dirt on the hydrophobic cylinder by forming the second recess on the hydrophobic cylinder.

[0060] The structure of the hydrophobic cylinder in this solution can form a cleaning part with a recessed structure when contacting the ground to accommodate and drive the sewage and garbage on the ground, achieving the cleaning effect on the ground, and can also achieve the effect of continuously switching between the arc surface structure and the cleaning part with the recessed structure, effectively keeping the hydrophobic cylinder in a clean state and reducing secondary pollution to the ground.

[0061] The outer cylinder part or the hydrophobic cylinder in this solution is made of a hydrophobic material, at least making the outer cylinder part have a structure that does not absorb sewage, effectively preventing the outer cylinder part from absorbing sewage. At the same time, the scraping part can effectively scrape off the sewage and garbage adhering to the outer surface of the outer cylinder part, enabling the outer cylinder part to be effectively kept clean and dry for a long time, not easily getting moldy and stinking, and not easily causing secondary pollution to the ground, greatly improving the user experience effect.

[0062] In this solution, a hydrophobic cylinder and a water absorption cylinder are provided, and the hydrophobic cylinder and the water absorption cylinder are set to be interchangeable structures to achieve the multi-functional use effect of the cleaning machine. Users can choose the hydrophobic cylinder to perform a cleaning process that does not absorb sewage on the ground but can drive the sewage and garbage for transfer and collection, or choose the water absorption cylinder to perform a cleaning process that absorbs sewage on the ground and collects garbage, improving the user's cleaning needs for the ground and thus improving the user experience effect.

[0063] In this solution, for the hydrophobic cylinder and the water absorption cylinder, a single scraping part can be set to scrape off the sewage and garbage on the hydrophobic cylinder and the water absorption cylinder, and the depression depth formed by the first recess or the second recess is set to be less than the interference depth of the scraping part embedded in the water absorption layer to form different scraping effects, thereby enabling a single scraping part to effectively and independently match to achieve the scraping effects on the hydrophobic cylinder and the water absorption cylinder, making the overall structure simple and having a better scraping effect.

Detailed implementation manners

[0078] In order to make the technical means, creative features, achieved purposes and functions of the present invention easy to understand, the present invention will be further described below in conjunction with specific embodiments.

[0079] Embodiment: The cleaning machine of the present invention, as Figures 1 to 13As shown in the composition, the cleaning machine is mainly equipped with a hydrophobic cylinder 1 to achieve the cleaning effect on the ground. At the same time, a water absorption cylinder 3 is also set to achieve the cleaning effect on the ground. The hydrophobic cylinder 1 and the water absorption cylinder 3 are set as an interchangeable installation structure for users to choose. Users can choose to clean the ground through the hydrophobic cylinder 1 or the water absorption cylinder 3 based on different conditions of the ground, so as to better meet the cleaning needs of users for the ground and improve the user experience effect.

[0080] The cleaning machine of this solution includes a machine body 100, and the machine body 100 is mainly used to move on the ground to achieve the cleaning treatment of the ground. Among them, the cleaning machine also includes a hydrophobic cylinder 1, and the hydrophobic cylinder 1 is set to be detachably installed on the machine body 100. Users can install the hydrophobic cylinder 1 in place or remove the hydrophobic cylinder 1. When the hydrophobic cylinder 1 is installed in place, it can be used to contact the ground for cleaning, mainly to achieve the driving and transfer collection of the sewage and garbage on the ground. Among them, at least the part of the hydrophobic cylinder 1 that contacts the ground is made of a hydrophobic material that does not absorb liquid and has a flexible structure, so that when the hydrophobic cylinder 1 contacts the ground, it can deform to form a scraping and cleaning effect on the ground, and form an effect of driving the sewage and garbage on the ground for driving and transfer through deformation. At the same time, the structure composed of hydrophobic material makes the outer surface of the hydrophobic cylinder 1 not absorb sewage when contacting the ground for cleaning, and only achieves the effect of accommodating and driving the transfer of sewage, so that the sewage and dirt, that is, the garbage, can only adhere to the outer surface of the hydrophobic cylinder 1, and will not be absorbed by the outer surface of the hydrophobic cylinder 1, so that the hydrophobic cylinder 1 can effectively maintain a clean and dry state, which is convenient for scraping off the sewage and garbage on the hydrophobic cylinder 1 and cleaning the outer surface of the hydrophobic cylinder 1, reducing the secondary pollution to the ground.

[0081] Among them, at least a part of the hydrophobic cylinder 1 in its radial direction is set as a deformable and expandable flexible structure. When the hydrophobic cylinder 1 rotates and rolls, the hydrophobic cylinder 1 can deform and expand in the radial direction. Under the deformed and expanded structure, the outer surface of the hydrophobic cylinder 1 is offset outward, so that the maximum diameter or maximum outer diameter of the hydrophobic cylinder 1 will increase, so as to realize scraping off the sewage and dirt under the deformed and expanded structure of the hydrophobic cylinder 1; specifically, when the hydrophobic cylinder 1 is installed in place and has not rotated and rolled and has not contacted the ground or has rotated and rolled and contacted the ground, a first concave portion 105 with a concave structure is formed on the outer surface of the hydrophobic cylinder 1. At this time, the hydrophobic cylinder 1 is installed in place but not used to clean the ground. The hydrophobic cylinder 1 can contact the ground or not contact the ground and is in a structure that has not rotated and rolled, that is, when the hydrophobic cylinder 1 is in the initial structure state, through the setting of the first concave portion 105, the first concave portion 105 is formed in the hydrophobic cylinder 1 in the initial structure state where it has not deformed and expanded, ensuring that the hydrophobic cylinder 1 can be effectively scraped off the sewage and dirt in the subsequent process to achieve the cleaning effect; at the same time, when the hydrophobic cylinder 1 is installed in place and rotates and rolls to contact the ground for cleaning, a second concave portion 106 with a concave structure is formed on the outer surface of the hydrophobic cylinder 1, that is, when the hydrophobic cylinder 1 is in place and rotates and rolls, at this time the hydrophobic cylinder 1 is used to clean the ground, and at this time the hydrophobic cylinder 1 deforms and expands to form the second concave portion 106. The second concave portion 106 is a concave structure formed when the maximum outer diameter of the hydrophobic cylinder 1 increases, realizing that the sewage and dirt can be effectively scraped off the hydrophobic cylinder 1 during the movement process, and then facilitating the effective cleaning of the outer surface of the hydrophobic cylinder 1 in the subsequent process; among them, the first concave portion 105 is set to be formed in the structure where the hydrophobic cylinder 1 has not deformed and expanded, that is, the first concave portion 105 is a concave structure formed in the initial structure state where the hydrophobic cylinder 1 has not rotated and rolled, that is, has not deformed and expanded, and the second concave portion 106 is set to be formed in the structure where the hydrophobic cylinder 1 has deformed and expanded, that is, the second concave portion 106 is a concave structure formed when the maximum outer diameter of the hydrophobic cylinder 1 increases during rotation and rolling, that is, during deformation and expansion, so that the maximum depression depth formed by the second concave portion 106 is deeper than the maximum depression depth formed by the first concave portion 105, that is, the maximum depression depth formed by the second concave portion 106 is larger than the maximum depression depth formed by the first concave portion 105, and then effectively realizing that the hydrophobic cylinder 1 can be effectively scraped with sewage and dirt in the subsequent process to achieve thorough cleaning, so that the sewage and dirt adsorbed on the outer surface of the hydrophobic cylinder 1 can be effectively scraped off.

[0082] Among them, for the structural part that scrapes the sewage and dirt on the outer surface of the hydrophobic cylinder 1, a scraping part 2 is also provided on the machine body 100. The scraping part 2 is set to be a convex structure for scraping the sewage and / or dirt on the hydrophobic cylinder 1. The scraping part 2 is a convex structure facing the outer surface of the hydrophobic cylinder 1, so that the scraping part 2 can form contact with the outer surface of the hydrophobic cylinder 1 and then realize scraping and cleaning of the outer surface of the hydrophobic cylinder 1. Specifically, when a first concave part 105 is formed on the hydrophobic cylinder 1, the scraping part 2 forms a structure in contact with the outer surface of the hydrophobic cylinder 1 and applies pressure, so that a first concave part 105 is formed on the outer surface of the hydrophobic cylinder 1. When the hydrophobic cylinder 1 is installed in place and does not rotate and roll, at this time, the scraping part 2 can contact the outer surface of the hydrophobic cylinder 1 and apply pressure, so that the area part corresponding to the position of the scraping part 2 on the outer surface of the hydrophobic cylinder 1 is sunken to form a first concave part 105 with a sunken structure. The first concave part 105 ensures that the hydrophobic cylinder 1 can be effectively scraped of sewage and dirt in the follow-up to achieve a cleaning effect. Specifically, when a second concave part 106 is formed on the hydrophobic cylinder 1, the scraping part 2 forms a structure in contact with the outer surface of the hydrophobic cylinder 1 and applies pressure, so that a second concave part 106 is formed on the outer surface of the hydrophobic cylinder 1. When the hydrophobic cylinder 1 is installed in place and rotates and rolls, at this time, the scraping part 2 can contact the outer surface of the hydrophobic cylinder 1 and apply pressure, so that the area part corresponding to the position of the scraping part 2 on the outer surface of the hydrophobic cylinder 1 is sunken to form a second concave part 106 with a sunken structure. The second concave part 106 ensures that the hydrophobic cylinder 1 can be effectively scraped of sewage and dirt in the follow-up to achieve a cleaning effect. At the same time, it is set that when the hydrophobic cylinder 1 rotates and rolls, it forms a structure that deforms and expands in the radial direction, so that the maximum sunken depth formed by the second concave part 106 is increased relative to the maximum sunken depth formed by the first concave part 105. When the hydrophobic cylinder 1 rotates and rolls, at this time, the hydrophobic cylinder 1 will deform and expand in the radial direction. In the state of deformation and expansion, the outer surface of the hydrophobic cylinder 1 will shift toward the outer side of the hydrophobic cylinder 1, thereby enabling the scraping part 2 to contact the outer surface of the hydrophobic cylinder 1 and form a contact pressure structure or a deep pressure structure that applies pressure. At the same time, the maximum sunken depth formed by the second concave part 106 will be increased relative to the maximum sunken depth formed by the first concave part 105, and finally the maximum sunken depth of the second concave part 106 will be deeper than the maximum sunken depth of the first concave part 105, realizing that the scraping part 2 scrapes the sewage and dirt on the outer surface of the hydrophobic cylinder 1 along the arc surface structure. At the same time, the sunken depth of the first concave part 105 is relatively small compared to the second sunken depth, so that when the hydrophobic cylinder 1 has the structure of the first concave part 105, it will not cause fatigue or even damage to a certain position on the outer surface of the hydrophobic cylinder 1. Even if the first concave part 105 is formed, it can effectively ensure that the hydrophobic cylinder 1 can be effectively reset and rebound to its initial shape, and will not cause the problem that the hydrophobic cylinder 1 cannot be effectively reset and rebound to its initial shape.

[0083] Wherein, when the scraping part 2 contacts and applies pressure to the outer surface of the hydrophobic cylinder 1, a part of the outer surface of the hydrophobic cylinder 1 is deformed toward the inner direction or the radial direction to form a first concave part 105 or a second concave part 106. During the process that the scraping part 2 contacts the outer surface of the hydrophobic cylinder 1 and applies pressure, mainly the outer surface of the hydrophobic cylinder 1 will shift outward to form a pressure-applying structure, that is, a pressure-applying structural effect is formed at the position where the outer surface of the hydrophobic cylinder 1 contacts the scraping part 2. It is not that the scraping part 2 actively applies pressure, but the outer surface of the hydrophobic cylinder 1 reversely forms an effect of applying pressure to the scraping part 2. At this time, the depression depth of the second concave part 106 will increase and become deeper. It can be understood that the positions of the first concave part 105 and the second concave part 106 overlap at least partially. The scraping part 2 can be set as a fixed structure and always located at the same position. Then, when the scraping part 2 contacts the hydrophobic cylinder 1 to form the first concave part 105 and the second concave part 106, both are located on the area part of the outer surface of the hydrophobic cylinder 1 corresponding to the position of the scraping part 2, that is, the first concave part 105 and the second concave part 106 are formed at the same position on the area part of the outer surface of the hydrophobic cylinder 1 corresponding to the position of the scraping part 2. The first concave part 105 and the second concave part 106 are concave structures formed by the hydrophobic cylinder 1 in two different states and can be at the same position. When the hydrophobic cylinder 1 rotates and rolls, different positions on the outer surface of the hydrophobic cylinder 1 in the rotation and rolling direction will sequentially contact the scraping part 2. However, the positions where the first concave part 105 and the second concave part 106 are formed on the outer surface of the hydrophobic cylinder 1 during rotation and rolling are always at the area part corresponding to the position of the scraping part 2, thereby constituting that the positions of the first concave part 105 and the second concave part 106 overlap at least partially, and only form structures with different depression depths. At the same time, the first concave part 105 or the second concave part 106 is also set above the rotation axis of the hydrophobic cylinder 1 to better remove the liquid and dirt on the hydrophobic cylinder 1 subsequently, and to realize a structure in which the scraped liquid and dirt flow downward to the first concave part 105 and the second concave part 106 and are separated from the outer surface of the hydrophobic cylinder 1. At the same time, it can prevent the problem that part of the liquid or dirt remains or is accommodated at the positions of the first concave part 105 and the second concave part 106, improve the scraping and separating effect of the scraping part 2 on the liquid and dirt on the hydrophobic cylinder 1, and improve the cleaning effect of the hydrophobic cylinder 1 on the ground.

[0084] It can be seen that in this solution, the scraping part 2 forms a structure for making contact with and applying pressure to the outer surface of the hydrophobic cylinder 1, or a structure for shallow pressing, to correspond to the formation of the first concave part 105 on the hydrophobic cylinder 1 when it is not moving, and to correspond to the formation of the second concave part 106 on the hydrophobic cylinder 1 when it is moving. This enables the hydrophobic cylinder 1 not to form a structure of being deeply pressed by the scraping part 2 when it is not in use for cleaning the ground, effectively preventing problems such as deformation that cannot be restored and easy breakage on the outer surface of the hydrophobic cylinder 1 due to long-term deep pressing by the scraping part 2, and greatly improving the safety and reliability of the hydrophobic cylinder 1.

[0085] In this solution, when the hydrophobic cylinder 1 contacts the ground, the area on the outer surface of the hydrophobic cylinder 1 corresponding to the ground constitutes a cleaning part 107 that is recessed towards the inner side of the outer surface of the hydrophobic cylinder 1. The cleaning part 107 is used to form a structure for scraping and cleaning the ground to drive the movement of sewage and / or dirt. The cleaning part 107 is set as a structure that can be switched between an arc surface structure and a recessed structure. When the hydrophobic cylinder 1 is on the ground, due to the pressure of the machine main body 100, it receives a certain downward pressure towards the ground, which causes a part of the outer surface of the hydrophobic cylinder 1 to deform towards the inner side, thereby forming the cleaning part 107 with a recessed structure. The cleaning part 107 forms a structure for scraping the sewage and garbage on the ground to collect the sewage and garbage into the cleaning part 107, and then drives and transfers them along the direction of rotational rolling. Among them, when the cleaning part 107 leaves the ground, the cleaning part 107 with a recessed structure will rebound and reset to deform into an arc surface structure, and form an elastic force for the sewage and garbage to achieve the effect of transferring and collecting the sewage and garbage. During the continuous rotational rolling movement of the hydrophobic cylinder 1, different positions on the outer surface of the hydrophobic cylinder 1 contact the ground respectively, and the cleaning part 107 with a recessed structure is formed in sequence. At the same time, a continuous cleaning part 107 is formed in the direction of rotational rolling, and the recessed structure rebounds and deforms back to the arc surface structure in sequence. The entire process realizes the cleaning effect on the ground. The first concave part 105 or the second concave part 106 is set above the cleaning part 107, and the cleaning part 107 is set below the rotation axis of the hydrophobic cylinder 1. The second concave part 106 is formed above the cleaning part 107 to scrape the sewage and garbage on the outer surface of the hydrophobic cylinder 1. Part of the sewage and garbage flows or drops downward along the scraping direction to be collected and processed. The cleaning part 107 is below the rotation axis of the hydrophobic cylinder 1 to contact the ground and deform to form the cleaning part 107. The cleaning part 107 accommodates the sewage and dirt and drives and transfers them upward along the direction of rotational rolling movement, thereby realizing the transfer and collection of the sewage and dirt into the cleaning machine.

[0086] In this solution, the area part of the outer surface of the hydrophobic cylinder 1, except for the first concave part 105 or the second concave part 106 and the cleaning part 107, is configured to be an arc surface structure in the rotational rolling direction, so that this area part is configured to be a continuous arc surface structure without a concave structure, that is, the area part does not form a concave structure. That is, except for the positions of the first concave part 105, the second concave part 106 and the cleaning part 107 on the outer surface of the hydrophobic cylinder 1 where concave structures are formed, the remaining positions are all formed into a continuous arc surface structure. A part of the outer surface of the hydrophobic cylinder 1 being an arc surface structure and not forming a concave structure makes it difficult for dirt and grime to accumulate on the outer surface of the hydrophobic cylinder 1. The structure that is not prone to dirt and grime accumulation enables the hydrophobic cylinder 1 to be effectively and simply cleaned, which is conducive to removing and collecting the waste liquid and dirt on the outer surface of the hydrophobic cylinder 1 and is not likely to cause secondary pollution to the ground. At this time, the arc surface structure of the outer surface of the hydrophobic cylinder 1 enables it to be effectively cleaned by the scraping part 2 in combination with clean water, which is conducive to removing and collecting the waste liquid and dirt on the outer surface of the hydrophobic cylinder 1.

[0087] Among them, when the scraping part 2 contacts the outer surface of the hydrophobic cylinder 1 to form the second concave part 106, at least the waste liquid and / or dirt on the outer surface of the hydrophobic cylinder 1 flow downward along the arc surface structure and are separated from the outer surface of the hydrophobic cylinder 1. During the rotational rolling movement of the hydrophobic cylinder 1, different positions on the outer surface of the hydrophobic cylinder 1 in the rotational rolling direction sequentially contact the scraping part 2, and the scraping part 2 sequentially forms the second concave part 106. The contact position between the scraping part 2 and the hydrophobic cylinder 1 will form an effect of blocking waste liquid and dirt, that is, an effect of scraping off waste liquid and dirt. When the waste liquid and dirt are scraped off, they will flow downward and fall off, and at least a part will flow along the arc surface structure on the outer surface of the hydrophobic cylinder 1. At the same time, part of the waste liquid and dirt will be separated from the outer surface of the hydrophobic cylinder 1 for collection, thereby realizing that the scraping part 2 scrapes the hydrophobic cylinder 1 clean. At this time, clean water can be combined to enable the scraping part 2 and clean water to act on the outer surface of the hydrophobic cylinder 1 together to clean the hydrophobic cylinder 1.

[0088] In this solution, when the hydrophobic cylinder 1 deforms and expands in the radial direction, the radius value R formed by the arc surface where the area part other than the second concave part 106 and the cleaning part 107 is located on the outer surface of the hydrophobic cylinder 1 is increased, and the expansion amount H formed by the increase is greater than or equal to 0.5 mm, or greater than or equal to 0.5 mm and greater than or equal to the maximum depression depth formed by the first concave part 105. That is, when the hydrophobic cylinder 1 rotates and rolls, the hydrophobic cylinder 1 will deform and expand in the radial direction at this time. In the state of deformation and expansion, the outer surface of the hydrophobic cylinder 1 will shift towards the outer side of the hydrophobic cylinder 1, so that the scraping part 2 contacts the outer surface of the hydrophobic cylinder 1 and forms a touch pressure structure or a deep pressure structure for applying pressure. At the same time, the maximum depression depth formed by the second concave part 106 will be increased relative to the maximum depression depth formed by the first concave part 105, and finally the maximum depression depth of the second concave part 106 will be deeper than the maximum depression depth of the first concave part 105. When the hydrophobic cylinder 1 deforms and expands, the radius value R formed by the arc surface where the area part other than the second concave part 106 and the cleaning part 107 is located on the outer surface of the hydrophobic cylinder 1 is increased. During the increasing process, a certain expansion amount H will be formed by the radius value R. Setting H to be greater than or equal to 0.5 mm, or greater than or equal to 0.5 mm and greater than or equal to the maximum depression depth formed by the first concave part 105 can ensure that under the deformed and expanded structure of the hydrophobic cylinder 1, the maximum depression depth formed by the second concave part 106 can be increased relative to the maximum depression depth formed by the first concave part 105, realizing that the scraping part 2 scrapes off the sewage and dirt on the outer surface of the hydrophobic cylinder 1 along the arc surface structure, and also ensuring that the hydrophobic cylinder 1 is prevented from being over-touched or over-pressed by the scraping part 2 to form fatigue or breakage. If the size of the expansion amount H is too large, it will form an over-deep pressure of the scraping part 2 on the outer surface of the hydrophobic cylinder 1. The over-deep pressure will reduce the deformation and resilience effect of this position on the outer surface of the hydrophobic cylinder 1, and then it will be difficult to reset and rebound the deformation, and even it is easy to have the problem of breakage. At the same time, over-touching easily causes problems such as jamming and vibration when the hydrophobic cylinder 1 rotates and rolls, affecting the stability and reliability of the movement of the hydrophobic cylinder 1.

[0089] Among them, when the hydrophobic cylinder 1 is deformed and expanded, a centrifugal force is formed in the outer direction of the hydrophobic cylinder 1. The centrifugal force is set so that the radius value R formed by the arc surface where a part of the outer surface of the hydrophobic cylinder 1 is located is configured to increase, and at least a part of the outer surface of the hydrophobic cylinder 1 is configured to shift in the outer direction of the outer surface of the hydrophobic cylinder 1. Specifically, when the hydrophobic cylinder 1 rotates and rolls, the hydrophobic cylinder 1 will form a centrifugal force in the direction of rotation and rolling. Under the action of the centrifugal force, a part of the hydrophobic cylinder 1 in its radial direction will deform and expand towards the outer direction, thereby causing a part or all of the outer surface of the hydrophobic cylinder 1 to shift towards the outer direction. That is, the radius value R formed by the arc surface where a part of the outer surface of the hydrophobic cylinder 1 is located is configured to increase. During the increasing process, the radius value R will form a certain amount of expansion, thereby realizing the structure in which a part of the outer surface of the hydrophobic cylinder 1 is configured to shift in the outer direction of the outer surface of the hydrophobic cylinder 1. Under the offset structure, the maximum depression depth formed by the second recess 106 will increase relative to the maximum depression depth formed by the first recess 105, and finally the maximum depression depth of the second recess 106 will be deeper than the maximum depression depth of the first recess 105, realizing that the scraping part 2 forms the scraping of the outer surface of the hydrophobic cylinder 1 along the arc surface structure to remove dirt and contaminants.

[0090] In the specific structure part of the hydrophobic cylinder 1 in this solution, the hydrophobic cylinder 1 includes an outer cylinder part 101 and an inner cylinder part 102. The outer cylinder part 101 is located at the outer ring position of the inner cylinder part 102, and the inner cylinder part 102 is located at the inner ring position of the outer cylinder part 101. At the same time, the outer cylinder part 101 and the inner cylinder part 102 have a certain length value in the direction of the rotation axis to form their length structure. A hollow-structured spacer area 104 is formed between the outer cylinder part 101 and the inner cylinder part 102 in the radial direction. The spacer area 104 is mainly surrounded by the outer surface of the inner cylinder part 102 and the inner surface of the outer cylinder part 101. The spacer area 104 makes the outer cylinder part 101 and the inner cylinder part 102 be separated from each other in the radial direction. A plurality of spacer parts 103 are arranged in the spacer area 104. The spacer parts 103 are arranged to be connected to the outer cylinder part 101 and the inner cylinder part 102 respectively. Specifically, the inner end of the spacer part 103 is connected to the outer surface of the inner cylinder part 102, and the outer end of the spacer part 103 is connected to the inner surface of the outer cylinder part 101, so as to realize that the spacer part 103 forms a connected structure between the outer cylinder part 101 and the inner cylinder part 102. When the inner cylinder part 102 rotates and rolls, the outer cylinder part 101 is driven to perform synchronous rotational rolling movement through the plurality of spacer parts 103. At the same time, the inner cylinder part 102 forms a support structure for the outer cylinder part 101 through the plurality of spacer parts 103. In the rotational rolling direction, a spacer area 104 is formed between two adjacent spacer parts 103, or a part of the spacer area 104 is formed. One spacer part 103 is arranged between two adjacent spacer areas 104, or a plurality of spacer parts 103 divide the spacer area 104 into multiple parts to form a part of the spacer area 104 between two adjacent spacer parts 103. Among them, when the hydrophobic cylinder 1 contacts the ground, a part of the outer surface of the hydrophobic cylinder 1 deforms towards the spacer area 104 to form a concave cleaning part 107, so that the cleaning part 107 is arranged to be concave towards the spacer area 104. When the hydrophobic cylinder 1 contacts the ground, it will bear the pressure of the machine body 100, so that a part of its outer surface will deform and sink towards the spacer area 104 to form a concave cleaning part 107. The cleaning part 107 is arranged to form a structure for driving the sewage and / or dirt to be transferred. The cleaning part 107 forms a scraping and cleaning effect on the ground to realize the accommodation and driving transfer of the sewage and / or dirt. At the same time, when the scraping part 2 applies pressure on the outer surface of the outer cylinder part 101, the corresponding area part on the outer surface of the outer cylinder part 101 also deforms towards the spacer area 104 to form a concave structure, so that the first concave part 105 or the second concave part 106 is also arranged to be concave towards the spacer area 104, and then the scraping part 2 can better scrape along the arc surface structure on the outer surface of the hydrophobic cylinder 1 to realize scraping off the sewage and garbage.

[0091] Among them, the cleaning part 107, the first concave part 105 or the second concave part 106 are arranged in a spaced distribution structure in the rotational rolling direction, and the first concave part 105 and the second concave part 106 are arranged above the cleaning part 107, so that the second concave part 106 is located above the cleaning part 107 to scrape the liquid stains and garbage on the outer surface of the hydrophobic cylinder 1, and part of the liquid stains and garbage flow or fall downward along the scraping direction to be collected and processed.

[0092] In this solution, when a part of the outer surface of the hydrophobic cylinder 1 deforms towards the spaced area 104 to form the cleaning part 107 with a concave structure, the maximum concave depth formed by setting the cleaning part 107 is greater than the maximum concave depth formed by the first concave part 105 and / or the second concave part 106, so that the cleaning part 107 has a deeper concave depth to accommodate the liquid stains and garbage for driving and transferring, and the first concave part 105 and the second concave part 106 have a relatively shallower concave depth compared with the cleaning part 107. Among them, the second concave part 106 forms the scraping part 2 to scrape the liquid stains and garbage on the outer surface of the hydrophobic cylinder 1. The deeper concave depth of the cleaning part 107 can achieve a better cleaning effect on the ground. The cleaning part 107 with a deeper concave depth can accommodate more liquid stains and dirt for driving and transferring, and then form a better contact with the ground to deform to form a scraping and cleaning effect on the ground, which can achieve an improved driving and transferring effect on the liquid stains and dirt, and further achieve an improved cleaning of the ground to be cleaner.

[0093] In this solution, the maximum concave depth of the first concave part 105 is set to be greater than 0 and less than or equal to one-third of the length distance H1 extended by the spacer part 103 in the rotational rolling direction. Among them, the maximum concave depth of the first concave part 105 being greater than 0 makes the scraping part 2 always in a contact structure and a pressure-applying structure on the outer surface of the hydrophobic cylinder 1, so that the first concave part 105 is always in a concave structure. At the same time, when the scraping part 2 forms the first concave part 105 on the outer surface of the hydrophobic cylinder 1, the maximum concave depth of the first concave part 105 is relatively shallow, so as to form a shallow-pressure structure in which the hydrophobic cylinder 1 is always in contact and pressed by the scraping part 2 when it is not rotating and rolling or not used for cleaning the ground, preventing the hydrophobic cylinder 1 from forming a deep-pressure structure when it is not rotating and rolling or not used for contacting the ground for cleaning. At the same time, it can prevent the outer surface of the hydrophobic cylinder 1 from being excessively worn or damaged, and improve the stability and reliability of the hydrophobic cylinder 1. If the scraping part 2 is in a deep-pressure structure on the outer surface of the hydrophobic cylinder 1 for a long time when the hydrophobic cylinder 1 is not rotating and rolling or not used for cleaning the ground to form the second concave part 106, it will cause fatigue loss at a certain position on the outer surface of the hydrophobic cylinder 1, and then lead to the inability to effectively rebound and restore to the initial shape, that is, to reset and rebound to the arc surface structure. Under the long-term continuous deep-pressure structure, problems such as breakage will occur, resulting in a reduction in the service life and reliability of the hydrophobic cylinder 1.

[0094] In this solution, alternatively, it is set that the maximum depression depth of the first recess 105 is greater than 0 and less than or equal to twice the thickness value H2 from the outer surface to the inner surface of the outer cylinder part 101. Among them, the fact that the maximum depression depth of the first recess 105 is greater than 0 makes the scraping part 2 always in a structure that contacts the outer surface of the hydrophobic cylinder 1 and exerts a pressing pressure, so that the first recess 105 always has a recessed structure. At the same time, when the scraping part 2 forms the first recess 105 on the outer surface of the hydrophobic cylinder 1, the maximum depression depth of the first recess 105 is relatively shallow, so as to form a structure in which the hydrophobic cylinder 1 is in a shallow pressure state of being continuously contacted and pressed by the scraping part 2 when it is not rotating and rolling or not used for cleaning the ground, preventing the hydrophobic cylinder 1 from forming a deep pressure structure when it is not rotating and rolling or not used for contacting the ground for cleaning. At the same time, it can prevent the outer surface of the hydrophobic cylinder 1 from being excessively worn or damaged, and improve the stability and reliability of the hydrophobic cylinder 1. If the scraping part 2 is in a deep pressure structure on the outer surface of the hydrophobic cylinder 1 for a long time when the hydrophobic cylinder 1 is not rotating and rolling or not used for cleaning the ground to form the second recess 106, it will cause fatigue loss at a certain position on the outer surface of the hydrophobic cylinder 1, and then it will be impossible to effectively rebound and return to the initial shape, that is, to reset and rebound to the arc surface structure. Under the structure of continuous deep pressure for a long time, problems such as breakage will occur, resulting in a reduction in the service life and reliability of the hydrophobic cylinder 1.

[0095] In this solution, it is set that the maximum depression depth of the second recess 106 is greater than or equal to one-third of the thickness value H2 from the outer surface to the inner surface of the outer cylinder part 101 and less than or equal to three times the thickness value H2. This can prevent the depression depth formed by the second recess 106 from being too large. When the scraping part 2 contacts and applies pressure on the outer surface of the hydrophobic cylinder 1 to form the second recess 106, although the depression depth of the second recess 106 is increased compared with that of the first recess 105, the problem of the depression depth of the second recess 106 being too deep will not occur. It can effectively prevent the outer cylinder part 101 from being excessively deeply pressed and causing problems such as excessive wear or breakage. At the same time, thereby forming that the scraping part 2 can better scrape along the arc surface structure on the outer surface of the hydrophobic cylinder 1 through the second recess 106 to scrape off the sewage and garbage, so that the sewage and dirt can be effectively scraped under the structure of the depression depth of the formed second recess 106. At the same time, it can prevent the outer surface of the hydrophobic cylinder 1 from being excessively worn or damaged, and improve the stability and reliability of the hydrophobic cylinder 1.

[0096] In this solution, alternatively, set the maximum depression depth of the second recess 106 to be greater than or equal to half of the thickness value H2 from the outer surface to the inner surface of the outer cylinder part 101 and less than or equal to half of the length distance H1 that the spacer part 103 extends in the rotational rolling direction. This can prevent the depression depth formed by the second recess 106 from being too large. When the scraping part 2 contacts and applies pressure on the outer surface of the hydrophobic cylinder 1, although the depression depth of the second recess 106 is increased relative to that of the first recess 105, the problem of the depression depth of the second recess 106 being too deep will not occur. This can effectively prevent the outer cylinder part 101 from being over-pressed deeply, resulting in excessive wear or damage. At the same time, thereby forming the scraping part 2 to better scrape along the arc surface structure on the outer surface of the hydrophobic cylinder 1 through the second recess 106 to scrape off the sewage and garbage. Under the structure of the depression depth of the formed second recess 106, it can effectively scrape the sewage and dirt, and at the same time prevent the outer surface of the hydrophobic cylinder 1 from being over-pressed deeply, resulting in wear or damage, and improve the stability and reliability of the hydrophobic cylinder 1.

[0097] In this solution, set the length distance H1 that the spacer part 103 extends in the rotational rolling direction to be greater than or equal to twice the thickness value H2 from the outer surface to the inner surface of the outer cylinder part 101 and less than or equal to the radius value formed by the arc surface where the outer surface of the outer cylinder part 101 is located. And set the thickness value H2 from the outer surface to the inner surface of the outer cylinder part 101 to be greater than or equal to 0.4 mm and less than or equal to 1.4 mm. Among them, the length distance H1 forms the length structure of the spacer part 103 in the rotational rolling direction. At this length distance, the spacer part 103 can be deformed and expanded. The thickness value H2 from the outer surface to the inner surface of the outer cylinder part 101 forms the thickness structure of the outer cylinder part 101 in the radial direction. Under this thickness structure, the outer surface of the outer cylinder part 101 can be effectively deformed and expanded, realizing that a part of the outer surface of the outer cylinder part 101 is offset outward relative to the spacer part 103 or relative to the inner cylinder part 102, and realizing that a part of the outer surface of the outer cylinder part 101 can contact the scraping part 2 to form a structure of deep pressure where it is contacted and pressured, thereby effectively forming the second recess 106. During this process, the maximum depression depth formed by the second recess 106 will increase relative to the maximum depression depth formed by the first recess 105, and finally the maximum depression depth of the second recess 106 is deeper than that of the first recess 105, thereby realizing that the scraping part 2 can effectively scrape and separate the sewage and dirt on the outer surface of the hydrophobic cylinder 1 through the second recess 106. At the same time, the thickness structure of the outer cylinder part 101 enables a part of the outer surface of the outer cylinder part 101 to be better deformed, effectively deformed toward the spacer area 104 to better form a depression structure, and thus achieve a better scraping and cleaning effect on the ground.

[0098] In this solution, it can be understood that regardless of whether the hydrophobic cylinder 1 rotates and rolls, and regardless of whether the hydrophobic cylinder 1 cleans the ground, if the scraping part 2 is always in a deep-pressure structure against the outer surface of the hydrophobic cylinder 1 to form the second concave part 106, it will cause fatigue loss at a certain position on the outer surface of the hydrophobic cylinder 1, and then it will be unable to effectively rebound and recover to the initial shape, that is, to reset and rebound to the arc surface structure. Under the long-term continuous deep-pressure structure, problems such as damage will occur, resulting in a reduced service life and reliability of the hydrophobic cylinder 1; considering the use environment and characteristics of the cleaning machine, the cleaning machine generally works for about 20 to 40 minutes, and most of the remaining time is in a non-working state. If the scraping part 2 forms a deep pressure on the outer surface of the hydrophobic cylinder 1 to form the second concave part 106 when the cleaning machine is in a non-working state, it will cause a certain position on the outer surface of the hydrophobic cylinder 1 to be deeply pressed for a long time to form a concave structure state with the second concave part 106 for a long time, and then fatigue or even damage will occur. If the scraping part 2 is always in a deep-pressure structure against the hydrophobic cylinder 1 to form the second concave part 106, it will reduce the deformation and rebound effect of this position on the outer surface of the hydrophobic cylinder 1, and then it will be difficult to reset and rebound and deform to restore to the initial arc surface structure shape, and even prone to damage problems.

[0099] In this solution, it can be understood that during the continuous rotation and rolling movement of the hydrophobic cylinder 1, the position on the outer surface of the hydrophobic cylinder 1 that comes into contact with the scraping part 2 is in a state of continuous change in the rotation and rolling movement direction. There will be no situation where a certain position on the outer surface of the hydrophobic cylinder 1 is continuously fixed and deeply pressed by the scraping part 2 to form the second concave part 106. Therefore, there will be no problem that a certain position on the outer surface of the hydrophobic cylinder 1 is fatigued and unable to recover to the reset shape, and there will be no problem that a certain position is damaged due to continuous deep pressing by the scraping part 2 to form the second concave part 106. It can better ensure that the outer surface of the hydrophobic cylinder 1 has a good reset and rebound deformation effect, and then better clean the ground and maintain a good effect of scraping off sewage and garbage with the scraping part 2, reducing secondary pollution to the ground.

[0100] In this solution, it can be understood that when the hydrophobic cylinder 1 is not used to contact the ground for cleaning, or when the cleaning machine is not working, the scraping part 2 contacts the hydrophobic cylinder 1 at this time to mainly form a shallow pressure structure to form the first concave part 105. Although the first concave part 105 is also a concave structure, the first concave part 105 is mainly a shallow pressure structure with a relatively shallow depression depth realized by the scraping part 2 pressing the hydrophobic cylinder 1 lightly, which will not cause fatigue or even damage to a certain position on the outer surface of the hydrophobic cylinder 1. Even if the first concave part 105 is formed, it can effectively ensure that the hydrophobic cylinder 1 can be effectively reset and rebound to its initial shape, and will not cause the problem that the hydrophobic cylinder 1 cannot be effectively reset and rebound to its initial shape. At the same time, by setting the scraping part 2 to form the first concave part 105 when the hydrophobic cylinder 1 is not moving, it is ensured that when the hydrophobic cylinder 1 is moving and deforming and expanding later, the hydrophobic cylinder 1 can effectively form an effect of being contacted and pressed by the scraping part 2, thereby effectively preventing the problem that the scraping part 2 cannot contact the outer surface of the hydrophobic cylinder 1, and preventing the problem that the scraping part 2 cannot scrape the sewage and dirt on the hydrophobic cylinder 1.

[0101] In this solution, when the hydrophobic cylinder 1 deforms and expands, at least the spacer part 103 and / or the outer cylinder part 101 can be configured to form a structure that deforms and expands. In the structure that deforms and expands, a structure is formed in which a part of the outer surface of the hydrophobic cylinder 1 deflects toward the outer side of the outer surface of the hydrophobic cylinder 1. One of the spacer part 103 or the outer cylinder part 101 can be set to be a deformable and expandable structure, or both the spacer part 103 and the outer cylinder part 101 can be set to be deformable and expandable structures. Thus, during the process of the hydrophobic cylinder 1 rotating and rolling, a structure in which the hydrophobic cylinder 1 expands outward in the radial direction is formed through the spacer part 103 or the outer cylinder part 101, so that a part of the outer surface of the hydrophobic cylinder 1 deflects toward the outer side of the outer surface of the hydrophobic cylinder 1, and a part of the outer surface of the outer cylinder part 101 can contact the scraping part 2 to form a deep pressure structure that is contacted and pressed, thereby effectively forming the second concave part 106. During this process, the maximum depression depth formed by the second concave part 106 will be increased relative to the maximum depression depth formed by the first concave part 105, and finally the maximum depression depth of the second concave part 106 is deeper than the maximum depression depth of the first concave part 105, so that the scraping part 2 can effectively scrape and separate the sewage and dirt on the outer surface of the hydrophobic cylinder 1 through the second concave part 106.

[0102] In this solution, for the structural part that deforms and expands the hydrophobic cylinder 1, the spacer 103 can be set to a flexible and deformable structure. When the hydrophobic cylinder 1 deforms and expands, the spacer 103 is configured to deform and expand along its length direction under the action of the centrifugal force, so as to form a structure in which the maximum depression depth of the second recess 106 increases; that is, when the plurality of spacers 103 are under the action of the centrifugal force, they will deform and expand along the length direction formed in the rotational rolling direction or the radial direction of the hydrophobic cylinder 1, so that the distance of the spaced space formed between the outer surface of the inner cylinder part 102 and the inner surface of the outer cylinder part 101 increases, that is, the space distance of the spacer area 104 in the radial direction of the hydrophobic cylinder 1 increases. Furthermore, the outer cylinder part 101 will expand outward relative to the inner cylinder part 102 as a whole under the deformation and expansion of the spacer 103, so that a part of the outer surface of the outer cylinder part 101 can contact the scraping part 2 to form a deep pressure structure that is contacted and pressurized, thereby effectively forming the second recess 106. During this process, the maximum depression depth of the second recess 106 will increase relative to the maximum depression depth of the first recess 105, and finally the maximum depression depth of the second recess 106 is deeper than the maximum depression depth of the first recess 105, that is, larger. At the same time, the outer surface of the outer cylinder part 101 can effectively contact the ground to form a contact scraping and cleaning structure that applies pressure, and can also improve the cleaning effect on the ground.

[0103] In this solution, in order to improve the stability of the effective formation of the cleaning part 107 and the second recess 106, and in order to improve the effective and stable deformation and expansion of the outer cylinder part 101, the thickness value H3 formed by the spacer 103 in the rotational rolling direction is set to be greater than or equal to 0.5 mm and less than or equal to 5 mm; the size limitation of the thickness value of the spacer 103 enables the spacer 103 to deform and expand stably and effectively under the action of the centrifugal force, so as to realize the overall outward offset of the outer cylinder part 101 and achieve the effect of improving the deformation and expansion of the spacer 103.

[0104] In this solution, in order to improve the stability of the effective formation of the cleaning part 107 and the second concave part 106, and in order to improve the effective and stable deformation and expansion of the outer cylinder part 101, and / or, the length distance H1 of the spacer part 103 extending out in the rotational rolling direction is set to be greater than or equal to twice the thickness value H3 of the spacer part 103 in the rotational rolling motion direction, and the thickness value H3 is set to be greater than or equal to 0.5 mm. The size limitation of the thickness value of the spacer part 103 enables the spacer part 103 to be deformed and expanded stably and effectively under the action of the centrifugal force. At the same time, the limitation of the length distance value of the spacer part 103 enables the spacer part 103 to be deformed and expanded effectively along its length direction, thereby realizing the overall offset of the outer cylinder part 101 towards the external direction and achieving the effect of improving the deformation and expansion of the spacer part 103.

[0105] In this solution, for the structural part of the hydrophobic cylinder 1 to be deformed and expanded, the outer cylinder part 101 can be set to have a flexible and deformable structure. When the hydrophobic cylinder 1 is deformed and expanded, at least a part of the area corresponding to the spacer area 104 on the outer surface of the outer cylinder part 101 is configured to be deformed and expanded towards the external direction of the hydrophobic cylinder 1 under the action of the centrifugal force, thereby forming a structure with an increased maximum depression depth of the second concave part 106; that is, when the outer cylinder part 101 is deformed under the action of the centrifugal force to form a deformation and expansion towards the external direction of the hydrophobic cylinder 1, the outer surface of the outer cylinder part 101 is offset towards the external direction relative to the inner cylinder part 102. Mainly, a part within the range of the area corresponding to the spacer area 104 on the outer surface of the outer cylinder will be deformed and expanded towards the external direction, thereby realizing that a part of the outer surface of the outer cylinder part 101 can contact the scraping part 2 to form a deep pressure structure of being contacted and pressured, thereby effectively forming the second concave part 106. During this process, the maximum depression depth of the second concave part 106 will be increased relative to the maximum depression depth of the first concave part 105, and finally the maximum depression depth of the second concave part 106 is deeper than the maximum depression depth of the first concave part 105, that is, larger. At this time, the scraping part 2 can scrape off the sewage and garbage adsorbed on the outer surface of the outer cylinder part 101. At the same time, the outer surface of the outer cylinder part 101 can effectively contact the ground to form a contact scraping and cleaning structure with pressure applied, and the cleaning effect on the ground can also be improved.

[0106] In this solution, in order to improve the stability of the effective formation of the cleaning part 107 and the second concave part 106, and in order to improve the effective and stable deformation expansion of the outer cylinder part 101, it is set that the arc length value formed in the rotational rolling direction of the region part on the outer surface of the outer cylinder part 101 that is configured as an arc surface structure and the region part corresponding to the spacer 104 is greater than or equal to the minimum arc length value formed in the rotational rolling direction of two adjacent spacer parts 103. By limiting the size of the arc length value formed by the region part on the outer surface of the outer cylinder part 101 corresponding to the position of the spacer 104, it is ensured that the arc length value in this region part of the outer surface of the outer cylinder part 101 has a moderate length. At this arc length value, the region part of the outer surface of the outer cylinder part 101 can be deformed and expanded towards the outside, so as to realize the overall offset of the outer cylinder part 101 towards the outside direction, and realize that a part of the outer surface of the outer cylinder part 101 can contact the scraping part 2 to form a deep pressure structure that is contacted and pressured, thereby effectively forming the second concave part 106.

[0107] And / or, in this solution, in order to improve the stability of the effective formation of the cleaning part 107 and the second concave part 106, and in order to improve the effective and stable deformation expansion of the outer cylinder part 101, it is set that the thickness value H2 from the outer surface to the inner surface of the outer cylinder part 101 is less than or equal to the thickness value H3 formed by the spacer part 103 in the rotational rolling direction. By limiting the thickness value H2 from the outer surface to the inner surface of the outer cylinder part 101, that is, the thickness in the radial direction of the outer cylinder part 101 is limited. Under this thickness structure, the outer surface of the outer cylinder part 101 can be effectively deformed and expanded, realizing the offset of the outer surface of the outer cylinder part 101 towards the outside direction relative to the spacer part 103 or relative to the inner cylinder part 102, and realizing that a part of the outer surface of the outer cylinder part 101 can contact the scraping part 2 to form a deep pressure structure that is contacted and pressured, thereby effectively forming the second concave part 106. The spacer part 103 effectively supports the outer cylinder part 101 to realize the effective synchronous rotational rolling movement of the inner cylinder part 102 driven by the inner cylinder part 102 through a plurality of spacer parts 103. At the same time, the cleaning part 107 is effectively formed on the outer surface of the outer cylinder part 101, and the effectiveness of the depression of the cleaning part 107 is improved.

[0108] In order to improve the multi-functional use effect of the cleaning machine so as to better meet the user's demand for cleaning the ground, in this solution, the cleaning machine further includes a water suction cylinder 3, and the water suction cylinder 3 is detachably installed on the machine body 100. When the water suction cylinder 3 is installed in place, it can contact the ground for cleaning treatment. At this time, the water drainage cylinder 1 is removed and not installed in place, and at least the part of the water suction cylinder 3 that contacts the ground is made of a liquid-absorbing water-absorbing material and has a soft structure. When the water suction cylinder 3 is installed in place, the outer surface of the water suction cylinder 3 contacts the ground and deforms to form a scraping and cleaning effect on the ground. At the same time, the part that contacts the ground will absorb clear water to form a wet scraping and cleaning of the ground in a wet structure. The part that has already contacted the ground will absorb the sewage generated during the ground cleaning process, and realize the movement and collection of the garbage after clamping, thereby realizing the cleaning effect on the ground.

[0109] Among them, the water suction cylinder 3 and the water drainage cylinder 1 are set to be interchangeable installation structures, forming a structure in which when the water drainage cylinder 1 is installed in place, the water suction cylinder 3 is not installed in place, and forming a structure in which when the water suction cylinder 3 is installed in place, the water drainage cylinder 1 is not installed in place, so that the user can choose to install the water drainage cylinder 1 in place or choose to install the water suction cylinder 3 in place. When the water drainage cylinder 1 is installed in place, the water drainage cylinder 1 can independently contact the ground for cleaning treatment. When the water suction cylinder 3 is installed in place, the water suction cylinder 3 can independently contact the ground for cleaning treatment. The user can manually install or remove the water drainage cylinder 1 or the water suction cylinder 3 according to the cleaning requirements of the ground, so as to realize the multi-functional use effect of the cleaning machine.

[0110] Among them, when the water suction cylinder 3 is installed in place, the scraping part 2 is configured to penetrate the outer surface of the water suction cylinder 3 and extend into the inner side of the outer surface of the water suction cylinder 3 to form an interfering structure, so as to realize that the scraping part 2 extends into the inner side of the outer surface of the water suction cylinder 3 to form a deep scraping structure. Under the formed interfering structure, the garbage clamped by the water suction cylinder 3 is effectively deeply scraped, and at the same time, the sewage absorbed by the water suction cylinder 3 is deeply scraped, so that the water suction cylinder 3 can be kept in a clean state. At the same time, it is set that the maximum interference depth of the interfering structure formed by the scraping part 2 on the water suction cylinder 3 is greater than the maximum depression depth formed by the first concave part 105. In this way, the scraping part 2 can form an interfering effect on the water suction cylinder 3 to deeply scrape the sewage and dirt, which is beneficial to scraping and cleaning the water suction cylinder 3. Subsequently, the water suction cylinder 3 can be cleaned and scraped clean by combining the clear water supplied to the water suction cylinder 3, reducing the secondary pollution of the water suction cylinder 3 to the ground, and improving the cleaning effect on the ground.

[0111] In this solution, the water absorption cylinder 3 is provided with a water absorption layer 301, and the outer surface of the water absorption layer 301 constitutes the outer surface of the water absorption cylinder 3. The water absorption layer 301 is made of a water-absorbent material and has a flexible structure. When the water absorption cylinder 3 is installed in place, it mainly contacts the ground through the water absorption layer 301 to clean the ground. The outer surface of the water absorption layer 301 has a flexible and deformable structure to achieve a scraping cleaning effect when contacting the ground, while absorbing the sewage and carrying the dirt, and then driving the transfer for collection. At the same time, the water absorption layer 301 can absorb clean water, and the clean water wets the water absorption layer 301 to achieve a scraping cleaning effect on the ground. During this process, the scraping part 2 contacts the water absorption layer 301 to scrape off the sewage and dirt carried by the water absorption layer 301, so as to achieve cleaning a part of the water absorption layer 301 in combination with clean water, thereby improving the cleaning effect on the ground and reducing the secondary pollution of the ground by the water absorption layer 301.

[0112] Among them, when the water absorption layer 301 contacts the ground or does not contact the ground, the scraping part 2 is configured to contact the water absorption layer 301 and extend into the water absorption layer 301 to form an interfering structure, so that the scraping part 2 can effectively scrape off the sewage and garbage carried on the water absorption layer 301. The water absorption layer 301 is always in contact with the scraping part 2 to form an interfering structure, so that the scraping part 2 forms a pressing structure on the water absorption cylinder 3 to form an interfering structure. Since the water absorption cylinder 3 needs to absorb the sewage, the water absorption cylinder 3 does not have a partition area 104 like the hydrophobic cylinder 1. This also makes it possible that even if the scraping part 2 continuously contacts and applies pressure to the water absorption cylinder 3, the water absorption cylinder 3 will not have a problem of being unable to restore its shape.

[0113] Among them, or, when the water absorption cylinder 3 rotates and rolls or does not rotate and roll, the scraping part 2 is configured to contact the water absorption layer 301 and extend into the water absorption layer 301 to form an interfering structure, so that the scraping part 2 can effectively scrape off the sewage and garbage carried on the water absorption layer 301. The water absorption layer 301 is always in contact with the scraping part 2 to form an interfering structure, so that the scraping part 2 forms a pressing structure on the water absorption cylinder 3 to form an interfering structure. Since the water absorption cylinder 3 needs to absorb the sewage, the water absorption cylinder 3 does not have a partition area 104 like the hydrophobic cylinder 1. This also makes it possible that even if the scraping part 2 continuously contacts and applies pressure to the water absorption cylinder 3, the water absorption cylinder 3 will not have a problem of being unable to restore its shape.

[0114] Among them, the maximum interference depth of the interference structure formed by the scraping part 2 on the water absorption layer 301 is greater than the maximum depression depth formed by the second concave part 106 and / or greater than one-third of the thickness value of the water absorption layer 301 in the radial direction. In this way, the scraping part 2 can achieve the interference effect of deeply scraping the sewage and dirt on the water absorption layer 301, improving the scraping effect on the water absorption layer 301. At the same time, this can prevent the depression depth formed by the second concave part 106 from being too large, so that the maximum depression depth of the second concave part 106 formed when the scraping part 2 presses against the outer surface of the hydrophobic cylinder 1 is less than the maximum interference depth formed by the scraping part 2 on the water absorption layer 301. Furthermore, it can better scrape the sewage and garbage along the arc surface structure on the outer surface of the hydrophobic cylinder 1, and at the same time prevent the outer surface of the hydrophobic cylinder 1 from being excessively worn or damaged, improving the stability and reliability of the hydrophobic cylinder 1.

[0115] In this solution, the rotation speed of the hydrophobic cylinder 1 and / or the water absorption cylinder 3 is greater than or equal to 200 r / min and less than or equal to 1000 r / min. At this rotation speed, the hydrophobic cylinder 1 can be deformed and expanded well to enable the scraping part 2 to scrape the sewage and dirt on the hydrophobic cylinder 1. At the same time, it can better form the cleaning part 107 to drive and transfer the sewage and dirt on the ground for collection, and the water absorption cylinder 3 can better clean the ground and be scraped by the scraping part 2 to remove the sewage and dirt. At this rotation speed, the hydrophobic cylinder 1 and the water absorption cylinder 3 have better stability and better cleaning effects on the ground. At this rotation speed, not only can the scraping part 2 effectively form a stable deep-pressure structure on the outer surface of the outer cylinder part 101 to form the second concave part 106, but also at this rotation speed, it can effectively prevent the hydrophobic cylinder 1 from being excessively deformed and expanded in the radial direction, preventing the problem that the depression depth formed when the scraping part 2 presses against the outer surface of the outer cylinder part 101 is too large, that is, the depression depth of the second concave part 106 is too large. It can effectively prevent the problem that the outer cylinder part 101 is excessively deeply pressed and causes excessive wear or damage.

[0116] In this solution, alternatively, the rotational rolling speeds of the hydrophobic cylinder 1 and the water absorption cylinder 3 are set to be the same to form a rotational rolling motion with a rotational speed V, and the rotational speed V is set to be greater than or equal to 300 r / min and less than or equal to 600 r / min. At this rotational speed V, the hydrophobic cylinder 1 can not only effectively contact the ground to form a good cleaning effect, but also can be better deformed and expanded in the radial direction, so that the scraping part 2 can effectively form a pressing structure on the outer surface of the outer cylinder part 101 to form the first concave part 105 or the second concave part 106. At the same time, at this rotational speed V, it can effectively prevent the hydrophobic cylinder 1 from being excessively deformed and expanded in the radial direction, and prevent the problem that the pressing depth formed when the scraping part 2 presses the outer surface of the outer cylinder part 101 is too large, that is, the depression depth of the second concave part 106 is too large, and can effectively prevent the problem of excessive wear or damage of the outer cylinder part 101 caused by excessive deep pressing. Among them, setting the rotational rolling speeds of the hydrophobic cylinder 1 and the water absorption cylinder 3 to be the same to form a rotational rolling motion with a rotational speed V, it can be understood that at the same rotational rolling speed, combined with the structures of the hydrophobic cylinder 1 and the water absorption cylinder 3 in this solution, it is possible to achieve without controlling the drive module to change the rotational speed, and to improve the continuity and stability of the drive module providing the same rotational speed. At the same rotational speed, the scraping part 2 can independently scrape the sewage and dirt on the hydrophobic cylinder 1 and the water absorption cylinder 3 respectively. At the same rotational speed, the hydrophobic cylinder 1 can be deformed and expanded to enable the outer surface of the hydrophobic cylinder 1 to be contacted by the scraping part 2 and form a pressing structure applying pressure, thereby realizing the effect of the scraping part 2 scraping the sewage and garbage on the hydrophobic cylinder 1. At the same time, at the same rotational speed, both the hydrophobic cylinder 1 and the water absorption cylinder 3 can achieve a better cleaning effect on the ground. The setting of this solution realizes that without controlling the drive module to change the rotational speed, the hydrophobic cylinder 1 and the water absorption cylinder 3 can also form a better cleaning effect on the ground, and there is no need to separately configure the drive module to provide different rotational speeds due to the interchangeable structure of the hydrophobic cylinder 1 and the water absorption cylinder 3. Only a single rotational speed needs to be set, and the overall control is simpler and the stability is better.

[0117] In this solution, alternatively, set the diameter value D1 formed by the outer surface of the water absorption cylinder 3 when it is not rotating and rolling to be greater than the diameter value D2 formed by the arc surface where the outer surface of the hydrophobic cylinder 1 is located when it is not rotating and rolling, and set D1 - D2 to be greater than or equal to 1 mm and less than or equal to 10 mm, or set D1 to be greater than or equal to 1.1 times D2 and less than or equal to 1.3 times D2. Under this dimensional limitation, that is, when the diameter value of the water absorption cylinder 3 is greater than that of the hydrophobic cylinder 1, when the water absorption cylinder 3 is installed in place and not rotating and rolling, an interference structure can be formed between the water absorption cylinder 3 and the scraping part 2. When the hydrophobic cylinder 1 is installed in place and not rotating and rolling, the scraping part 2 forms a structure that lightly presses on the hydrophobic cylinder 1, thereby forming a first concave part 105 with a relatively shallow depression depth. At the same time, set D1 - D2 to be greater than or equal to 1 mm and less than or equal to 10 mm, or set D1 to be greater than or equal to 1.1 times D2 and less than or equal to 1.3 times D2. Under this dimensional limitation, it can be ensured that the hydrophobic cylinder 1 forms a structure that is lightly pressed by the scraping part 2 without deformation and expansion, forming a first concave part 105 with a relatively shallow depression depth, and ensuring that the hydrophobic cylinder 1 can form a structure that is deeply pressed by the scraping part 2 under the deformed and expanded structure, forming a second concave part 106 with a relatively deep depression depth. This not only realizes that the scraping part 2 can form a deep scraping effect on the water absorption cylinder 3, improving the effect of scraping off the contaminated liquid and dirt on the water absorption cylinder 3, but also realizes that the scraping part 2 forms an effective scraping effect on the outer surface of the hydrophobic cylinder 1 along the arc surface structure, preventing the hydrophobic cylinder 1 from being overly deeply pressed by the scraping part 2 to form fatigue or damage. If it is overly touched or deeply pressed, the deformation and rebound effect at this position on the outer surface of the hydrophobic cylinder 1 will be reduced, and then it will be difficult to reset and rebound, and even prone to damage.

[0118] In this solution, alternatively, set the structure such that when the water absorption cylinder 3 and the hydrophobic cylinder 1 are respectively installed in place, they both rotate and roll around the same rotation axis. Among them, when the water absorption cylinder 3 is installed in place and not rotating and rolling or rotating and rolling, it forms an interference structure in contact with the scraping part 2, realizing that the scraping part 2 forms a pressing structure on the water absorption cylinder 3 to form an interference structure. Since the water absorption cylinder 3 is used to absorb the contaminated liquid, the water absorption cylinder 3 does not have an interval area 104 like the hydrophobic cylinder 1. This also means that even if the scraping part 2 continuously contacts and applies pressure to the water absorption cylinder 3, there will be no problem that the water absorption cylinder 3 cannot return to its original shape. Among them, when the water absorption cylinder 3 and the hydrophobic cylinder 1 are installed in place interchangeably, when they are independently installed in place, they are both installed at the same docking position to realize independently rotating and rolling around the same rotation axis respectively, improving the structure of their interchangeability to be simpler, and the adaptability of their interchangeability to be better, facilitating the user to perform the interchange operation.

[0119] It can be seen that in this solution, the same scraping part 2 can be used to scrape off the sewage and garbage from the hydrophobic cylinder 1 and the water absorption cylinder 3 respectively, without setting up multiple scraping parts 2 to respectively adapt to the hydrophobic cylinder 1 and the water absorption cylinder 3 for scraping off the sewage and garbage. This makes the overall structure simple, with lower costs, and the adaptability of the same scraping part 2 to the hydrophobic cylinder 1 and the water absorption cylinder 3 is better, and the effects of scraping off the sewage and garbage respectively are better, which can effectively prevent secondary pollution of the ground by the hydrophobic cylinder 1 or the water absorption cylinder 3.

[0120] In this solution, the outer cylinder part 101 or the hydrophobic cylinder 1 made of hydrophobic material will not absorb sewage, that is, neither sewage nor clean water will be absorbed. This enables the sewage and dirt, that is, garbage, to only adhere to the outer surface of the outer cylinder part 101, rather than being absorbed by the outer cylinder part 101. As a result, the outer cylinder part 101 can effectively maintain an arc-shaped structure, facilitating the scraping off of sewage and garbage from the outer cylinder part 101 to keep it clean and dry. There is no need to set up a drying mechanism such as a drying or air-drying device. The overall structure is simple, with low costs, and the cleaning effect on the ground is good. At the same time, the hydrophobic cylinder 1 made of hydrophobic material can form a flowing cleaning or flushing cleaning effect by supplying clean water to the outer surface of the hydrophobic cylinder 1. Combining the arc-shaped structure of the outer surface of the hydrophobic cylinder 1 and the structure that is not prone to accumulating dirt, it is very simple to clean the outer surface of the hydrophobic cylinder 1. After the outer surface of the hydrophobic cylinder 1 is cleaned, it continuously contacts the ground for cleaning treatment.

[0121] In this solution, the water-absorbing material can be, for example, cloth material, fluff material, sponge material, etc. The water absorption cylinder 3 or the water absorption layer 301 made of water-absorbing material can effectively absorb the sewage on the ground and carry the garbage, so as to clean the ground.

[0122] In this solution, the hydrophobic material can be, for example, silicone material, rubber material, silicone rubber material, etc. The hydrophobic cylinder 1 or the outer cylinder part 101 made of hydrophobic material can form a structure that does not absorb the sewage on the ground, but can form a structure to accommodate and drive the transfer of sewage and garbage through the cleaning part 107, so as to clean the ground.

[0123] In this solution, deep pressure can be understood as the relatively deep depression depth formed when the scraping part 2 contacts and applies pressure on the hydrophobic cylinder 1, that is, a structure forming deep pressure; shallow pressure can be understood as the relatively shallow depression depth formed when the scraping part 2 contacts and applies pressure on the hydrophobic cylinder 1, that is, a structure forming shallow pressure. Specifically, in this solution, when the second recess 106 is formed, the scraping part 2 forms a deep pressure structure on the hydrophobic cylinder 1, and when the first recess 105 is formed, the scraping part 2 forms a shallow pressure structure on the hydrophobic cylinder 1. The maximum depression depth of the second recess 106 is greater than the maximum depression depth of the first recess 105.

[0124] In this solution, the contaminated liquid is sewage, which is the sewage formed during the floor cleaning process by the cleaning machine, and the contaminants are garbage, which are the garbage driven during the floor cleaning process by the cleaning machine. Of course, it also includes the mixture of the contaminated liquid and the contaminants, that is, the mixture of sewage and garbage. The hydrophobic cylinder 1 is used to accommodate and drive the transfer of sewage, garbage, or the mixture of sewage and garbage, achieving the transfer and collection effect of the contaminated liquid and the contaminants. The water absorption cylinder 3 is used to absorb sewage and carry garbage for driving transfer, achieving the transfer and collection effect of the contaminated liquid and the contaminants.

[0125] In this solution, the cleaning machine can be set to a handheld structure, such as a handheld floor washer, a handheld floor mop, etc., or it can be set to a self - mobile structure, such as a self - mobile cleaning robot, a self - mobile floor washing robot, etc. It only needs to correspondingly set the structures such as the hydrophobic cylinder 1, the water absorption cylinder 3, the scraping part 2, etc. of this solution.

[0126] Working principle: For the cleaning machine in this solution, the cleaning machine mainly sets the hydrophobic cylinder 1 to achieve the floor cleaning effect. When the hydrophobic cylinder 1 contacts the ground, a cleaning part 107 with a concave structure can be formed. Through the cleaning part 107, it forms a structure for accommodating the contaminated liquid and the contaminants and driving their transfer. At the same time, a scraping part 2 is provided for the hydrophobic cylinder 1. The scraping part 2 forms a structure that contacts the outer surface of the hydrophobic cylinder 1 and applies pressure, so that the hydrophobic cylinder 1 forms a first concave part 105 when not in contact with the ground for cleaning, and a second concave part 106 when in contact with the ground for cleaning. At the same time, the second concave part 106 will increase relative to the first concave part 105 when the hydrophobic cylinder 1 deforms and expands, so that the maximum depression depth formed by the second concave part 106 is greater than the maximum depression depth formed by the first concave part 105. This can effectively prevent the problem that the hydrophobic cylinder 1 cannot effectively rebound to restore its shape, improving the safety and reliability of the hydrophobic cylinder 1 and preventing the hydrophobic cylinder 1 from being damaged. At the same time, the outer surface of the hydrophobic cylinder 1 can continuously switch between the concave structure and the arc surface structure. By contacting the ground, the cleaning part 107 with a concave structure is formed, and by not contacting the ground, it returns to the arc surface structure, so that the hydrophobic cylinder 1 can effectively maintain a clean and dry state, reducing secondary pollution to the ground and improving the floor cleaning effect.
