Generally, a drum is set to absorb or adsorb sewage on the ground and then carry garbage for transfer. Among them, a structure for scraping sewage and garbage is also set to scrape off the sewage and garbage absorbed or adsorbed on the drum. However, the existing scraping structure is mainly a structure that presses the drum all the time.

[0046] Compared with the prior art, the utility model has the following beneficial effects:

[0047] The surface cleaning equipment of this scheme is provided with a liquid-repelling cylinder and a liquid-absorbing cylinder, and the liquid-repelling cylinder and the liquid-absorbing cylinder are arranged to be interchangeable structures to achieve the multifunctional use effect of the surface cleaning equipment. The user can follow up and choose to install the liquid-repelling cylinder or the liquid-absorbing cylinder in place to meet the cleaning needs of the floor, thereby improving the user's use experience.

[0048] In this solution, the liquid-repelling cylinder can achieve the cleaning effect on the ground without absorbing dirty liquid. It can contain dirty liquid and dirt and drive the transfer and collection without absorbing dirty liquid. The liquid-absorbing cylinder can absorb dirty liquid and carry dirt for transfer. Users can choose a liquid-repelling cylinder or a liquid-absorbing cylinder to clean the ground according to the actual situation of the ground, and it has a multi-functional use effect.

[0049] In the present solution, the liquid-repelling cylinder can be deformed and expanded. When it is deformed and expanded, it can be touched and pressed by the scraping part to scrape off dirty liquid and dirt. When it is not deformed excessively, it cannot be touched and pressed by the scraping part, so that the liquid-repelling cylinder is touched and pressed by the scraping part only when it is used to clean the floor. This solves the problem that the liquid-repelling cylinder is always touched and pressed by the scraping part regardless of whether it is cleaning the floor or not, prevents the problem that the liquid-repelling cylinder cannot effectively restore its shape due to being continuously touched and pressed, and improves its reliability in use.

[0050] In this solution, a liquid-repelling cylinder is provided to clean the floor. At the same time, the liquid-repelling cylinder is not touched or pressed by the scraper when it is not rotating and rolling, so that any position on the outer surface of the liquid-repelling cylinder will not be constantly touched or pressed by the scraper when the liquid-repelling cylinder is not in use. This can effectively prevent the outer surface of the liquid-repelling cylinder from being deformed and unable to recover its shape or being easily damaged due to long-term contact and pressure by the scraper, thereby greatly improving the safety and reliability of the liquid-repelling cylinder.

[0051] In the present solution, the liquid-repelling cylinder is arranged so that it can be touched and pressed by the scraping part only when it is deformed and expanded, and will not be touched and pressed by the scraping part when it is not deformed and expanded, so that the scraping part can effectively remove the dirty liquid and garbage adhered to the outer surface of the liquid-repelling cylinder only when the liquid-repelling cylinder contacts the ground for movement and cleaning, so that the liquid-repelling cylinder can be effectively kept in a clean state.

[0052] In the present scheme, the liquid-repelling cylinder is configured to have a structure that can expand in at least the radial direction, so as to realize the expansion of the liquid-repelling cylinder in the radial direction during the rotational rolling motion, so as to realize the contact and pressure of the scraping part of the liquid-repelling cylinder to form the scraping part. There is no need to set up any power mechanism to provide power so that the scraping part forms the contact and pressure on the liquid-repelling cylinder. Instead, the outer surface of the liquid-repelling cylinder is formed to be contacted and pressed by the scraping part by the swinging force formed by the rotational rolling motion of the liquid-repelling cylinder itself. The overall structure is simple, low in cost, and highly reliable, and can effectively prevent the problem of long-term continuous contact and pressure of the scraping part on the outer surface of the liquid-repelling cylinder.

[0053] In this solution, the expansion structure of the liquid-repelling cylinder in the radial direction is fully utilized to realize the structure that can form a contact pressure with the scraper, thereby realizing the effect of the scraper to scrape away dirty liquid and garbage from the liquid-repelling cylinder. The structure is simple and the reliability is high.

[0054] In this solution, full use is made of the expansion structure of the liquid-repellent cylinder in the radial direction to realize that the outer surface of the liquid-repellent cylinder can effectively contact the ground to form a dirt-removing portion with a concave structure. The dirt-removing portion can effectively scrape the ground to scrape and collect the dirty liquid and dirt on the ground, and realize the effect of driving the collection and transfer along the rotating rolling direction.

[0055] In this solution, the structural and dimensional settings of the liquid-repelling cylinder enable it to effectively form a structure that is not touched or pressed by the scraping part when it is not rotating and rolling, and to effectively form a structure that is touched or pressed by the scraping part when it is rotating and rolling, thereby improving the stability and reliability of the contact and pressure between the liquid-repelling cylinder and the scraping part.

[0056] The liquid-repelling cylinder of the present invention has an arc-shaped structure when it is not in contact with the ground. The arc-shaped structure can effectively scrape and clean the outer surface of the liquid-repelling cylinder, which can effectively keep the liquid-repelling cylinder in a clean and dry state, and improve the effect of removing dirty liquid and garbage from the liquid-repelling cylinder.

[0057] The structural setting and size setting of the liquid-repelling cylinder of this scheme can enable the dirt removal part to effectively form and realize the scraping and cleaning effect on the ground, and at the same time effectively form a rebound-propelled transfer effect on the driven dirty liquid and garbage, thereby improving the transfer effect of the dirty liquid and garbage, and improving the effectiveness of keeping the liquid-repelling cylinder in a clean state.

[0058] The structure of the liquid-repellent cylinder of the present scheme can form a concave structure of the dirt removal part when it contacts the ground to accommodate the dirty liquid and garbage on the ground and drive and transfer them, thereby achieving a cleaning effect on the ground, and can achieve the effect of continuous switching between the arc surface structure and the concave structure of the dirt removal part, which can effectively keep the liquid-repellent cylinder in a clean state and reduce secondary pollution to the ground.

[0059] The outer cylinder or liquid-repellent cylinder of the present scheme is configured to be composed of a hydrophobic material, so that at least the outer cylinder has a structure that does not absorb dirty liquid, which can effectively prevent the sewage from being absorbed by the outer cylinder. At the same time, the scraping part can effectively scrape off the sewage and garbage adhering to the outer surface of the outer cylinder, so that the outer cylinder can be effectively kept in a clean and dry state for a long time, is not easy to mold and stink, and is not easy to form secondary pollution to the ground, which greatly improves the user experience.

[0060] In the present scheme, a scraping part can be provided for the liquid-repelling cylinder and the liquid-absorbing cylinder to scrape away dirty liquid and garbage, and the depth of the depression formed by the scraping part is set to be smaller than the embedding depth of the scraping part in the liquid-absorbing cylinder to form different scraping effects, thereby achieving that a single scraping part can effectively and independently match the scraping effect on the liquid-repelling cylinder and the liquid-absorbing cylinder, so that the overall structure is simple and the scraping effect is better.

DETAILED DESCRIPTION

[0075] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further described below in conjunction with specific embodiments.

[0076] Embodiment: The surface cleaning device of the utility model, such as Figures 1 to 13 As shown in the structure, the surface cleaning device is mainly used to achieve a cleaning effect, wherein a replaceable installation structure is realized by setting a liquid-repellent cylinder 1 and a liquid-absorbent cylinder 3, thereby realizing the multifunctional use effect of the surface cleaning device, so as to better meet the cleaning needs of users and enhance the user's use experience.

[0077] The surface cleaning device of the present scheme includes a device body 100, which is mainly used to move on the ground to achieve cleaning treatment of the ground. Specifically, the surface cleaning device also includes a liquid-repelling cylinder 1, which is configured to be detachably installed on the device body 100, and at least the part of the liquid-repelling cylinder 1 that is used to contact the ground is configured to be composed of a liquid-repelling material that does not absorb liquid and has a soft structure, so that when the liquid-repelling cylinder 1 is installed in place, a part of the outer surface of the liquid-repelling cylinder 1 will be deformed due to contact with the ground to achieve the cleaning effect on the ground, and the structure formed by the deformation is used to drive and transfer the dirty liquid and dirt on the ground, so as to clean the ground; the surface cleaning device also includes a liquid-absorbing cylinder 3, which is configured to be detachably installed on the device body 100, and at least the part of the liquid-absorbing cylinder 3 that is used to contact the ground is configured to be composed of a liquid-absorbing material that can absorb liquid and has a soft structure, and the liquid-absorbing material is a liquid-absorbing material. The water-based material enables that when the liquid suction cylinder 3 is installed in place, a part of the liquid suction cylinder 3 contacts the ground and deforms to achieve a scraping and cleaning effect on the ground, and realizes the absorption and transfer of dirty liquid on the ground, as well as the clamped dirt to drive and transfer, so as to clean the ground; wherein, the liquid-repelling cylinder 1 and the liquid suction cylinder 3 are arranged to be interchangeable to form a structure that can be independently installed on the device body 100 respectively. By arranging the liquid-repelling cylinder 1 and the liquid suction cylinder 3 as interchangeable structures, the user can choose to install the liquid-repelling cylinder 1 or the liquid suction cylinder 3 in place based on different conditions of the ground and based on the cleaning needs of the ground. When the liquid-repelling cylinder 1 is installed in place, the liquid-repelling cylinder 1 can be used to independently clean the ground, and when the liquid suction cylinder 3 is installed in place, the liquid suction cylinder 3 can be used to independently clean the ground, thereby realizing the multi-functional use effect of the surface cleaning equipment and improving the user's experience.

[0078] As for the specific structural part, in the present scheme, at least a part of the liquid-repelling cylinder 1 in its radial direction can be set to a flexible structure that can be deformed and expanded, and the liquid-absorbing cylinder 3 can be set to a structure that cannot be deformed and expanded in its radial direction, so that the liquid-repelling cylinder 1 can be deformed and expanded when the liquid-repelling cylinder 1 is installed in place and performs a rotational rolling motion, and the liquid-absorbing cylinder 3 cannot be deformed and expanded when the liquid-absorbing cylinder 3 is installed in place and performs a rotational rolling motion, so that any position on the outer surface of the liquid-repelling cylinder 1 will not appear in a state of being constantly touched and pressed by the scraper 2 when the liquid-repelling cylinder 1 is not deformed and expanded, and at the same time, the liquid-repelling cylinder 1 can only be contacted and pressured by the scraper 2 when it is used to clean the floor to clean the liquid-repelling cylinder 1; at the same time, so that the liquid-absorbing cylinder 3 can be subsequently formed with a structure that is always interfered with by the scraper 2, the scraper 2 continues to contact and apply pressure to the liquid-absorbing cylinder 3 to form an interference structure.

[0079] In the specific structural part, in the present scheme, at least a part of the liquid-repelling cylinder 1 in its radial direction is set to be a flexible structure that can be deformed and expanded, and the liquid-absorbing cylinder 3 is set to be a structure that can be deformed and expanded in the radial direction, but the amount of expansion that the liquid-absorbing cylinder 3 can undergo is smaller than the amount of expansion that the liquid-repelling cylinder 1 can undergo, so that when the liquid-repelling cylinder 1 is installed in place and performs a rotational rolling motion, the liquid-repelling cylinder 1 can undergo deformation and expansion, and when the liquid-absorbing cylinder 3 is installed in place and performs a rotational rolling motion, the liquid-absorbing cylinder 3 can undergo deformation and expansion, but the amount of expansion formed when the liquid-absorbing cylinder 3 undergoes deformation and expansion is smaller than the amount of expansion formed when the liquid-repelling cylinder 1 undergoes deformation and expansion, So as to subsequently achieve that no position on the outer surface of the liquid-repelling cylinder 1 will be in a state where the scraper 2 is always touching and pressing the liquid-repelling cylinder 1 when the liquid-repelling cylinder 1 is not deformed and expanded, and at the same time, the liquid-repelling cylinder 1 can be contacted and pressed by the scraper 2 only when it is used to clean the floor to clean the liquid-repelling cylinder 1; at the same time, the liquid-absorbing cylinder 3 has a certain deformation and expansion structure to form a better cleaning effect on the floor, and a better scraping and dragging cleaning effect on the floor is achieved when it is deformed and expanded, and subsequently the liquid-absorbing cylinder 3 is structured to be interfered with by the scraper 2, so that the scraper 2 continues to contact and apply pressure to the liquid-absorbing cylinder 3 to form an interference structure.

[0080] In order to scrape off the dirty liquid and dirt on the liquid-repelling cylinder 1 or the liquid-absorbing cylinder 3, the present scheme also provides a scraper 2 on the device body 100. The scraper 2 can be a fixed installation structure or a detachable installation structure. The scraper 2 is mainly set to be a raised structure to scrape off the dirty liquid and / or dirt on the liquid-repelling cylinder 1 and the liquid-absorbing cylinder 3 respectively. The scraper 2 is mainly a raised structure toward the outer surface of the liquid-repelling cylinder 1 or the liquid-absorbing cylinder 3, so that when the liquid-repelling cylinder 1 is installed in place and does not perform a rotational rolling motion, the scraper 2 forms a structure that does not contact the outer surface of the liquid-repelling cylinder 1 and does not apply pressure, or forms a structure that contacts the outer surface of the liquid-repelling cylinder 1 but does not apply pressure. At this time, any position on the outer surface of the liquid-repelling cylinder 1 will not appear in a state of being constantly touched and pressed by the scraper 2 when the liquid-repelling cylinder 1 does not perform a rotational rolling motion, which can effectively prevent The outer surface of the liquid-repelling cylinder 1 is deformed and cannot recover its shape and is easily damaged due to the long-term contact and pressure of the scraper 2 when the liquid-repelling cylinder 1 is not used to clean the ground. At the same time, when the liquid-repelling cylinder 1 is installed in place and rotates and rolls, the scraper 2 forms a contact and pressure structure on a part of the outer surface of the liquid-repelling cylinder 1, and a scraping portion 105 with a concave structure is formed on the outer surface of the liquid-repelling cylinder 1. The position on the outer surface of the liquid-repelling cylinder 1 that is contacted and pressured by the scraper 2 is formed with a concave scraping portion 105, which is mainly formed toward the inner side of the liquid-repelling cylinder 1. At this time, the scraper 2 can scrape off the dirty liquid and garbage adsorbed on the outer surface of the outer cylinder 101, thereby effectively scraping off the dirty liquid and dirt on the outer surface of the liquid-repelling cylinder 1, so that the liquid-repelling cylinder 1 can be kept in a clean and dry state, and the liquid-repelling cylinder 1 can be more easily cleaned.

[0081] It can be seen that in the present scheme, the liquid-repelling cylinder 1 can be deformed and expanded. When it is deformed and expanded, it can be touched and pressed by the scraping part 2 to scrape off dirty liquid and dirt. When it is not deformed excessively, it cannot be touched and pressed by the scraping part 2. The liquid-repelling cylinder 1 can be in a continuous initial structural state when not used to clean the floor to form a structure in which the scraping part 2 does not touch and press the outer surface of the liquid-repelling cylinder 1, so that the liquid-repelling cylinder 1 is touched and pressed by the scraping part 2 only when it is used to clean the floor. This solves the problem that the liquid-repelling cylinder 1 is always touched and pressed by the scraping part 2 regardless of whether it is cleaning the floor, prevents the liquid-repelling cylinder 1 from being unable to effectively restore its shape due to being constantly touched and pressed, and improves its reliability in use.

[0082] Among them, when the liquid suction cylinder 3 is installed in place and performs a rotating and rolling motion, the scraper portion 2 is formed to extend into the inner side of the outer surface of the liquid suction cylinder 3 to form a mutual interference structure. After the liquid-repelling cylinder 1 is removed, it can be replaced to install the liquid suction cylinder 3 in place. At this time, the scraper portion 2 will form an interference structure with the liquid suction cylinder 3, mainly in that the scraper portion 2 extends into the inner side of the outer surface of the liquid suction cylinder 3 to form a mutual interference structure. When the liquid suction cylinder 3 performs a rotating and rolling motion, the scraper portion 2 will form a sequential interference structure with different positions on the outer surface of the liquid suction cylinder 3, and form a structure for scraping off the dirty liquid and dirt on the liquid suction cylinder 3 under the contact and pressure structure, so that the scraper portion 2 can not only independently scrape off the dirty liquid and dirt on the liquid-repelling cylinder 1, but also can realize the structure that the same scraper portion 2 scrapes off the dirty liquid and dirt on the liquid suction cylinder 3.

[0083] In the present scheme, when the liquid-repelling cylinder 1 performs a rotational rolling motion, a portion of the liquid-repelling cylinder 1 in the radial direction is configured to be deformed and expanded and a throwing force is formed toward the outer side of the liquid-repelling cylinder 1. The throwing force is configured to at least cause a portion of the outer surface of the liquid-repelling cylinder 1 to be offset toward the outer side, thereby increasing the spatial area covered by the liquid-repelling cylinder 1 in the radial direction; specifically, when the liquid-repelling cylinder 1 performs a rotational rolling motion, the liquid-repelling cylinder 1 will form a throwing force along the rotational rolling direction, and under the action of the throwing force, a portion of the liquid-repelling cylinder 1 in the radial direction will be deformed and expanded toward the outer side, thereby causing a portion or all of the outer surface of the liquid-repelling cylinder 1 to be offset toward the outer side, that is, the diameter formed by the arc surface or annular arc surface on which the outer surface of the liquid-repelling cylinder 1 is located will be The expansion is carried out, thereby increasing the covered spatial area formed by the cross-section of the liquid-repelling cylinder 1 in the radial direction or in the rotational rolling direction, that is, the outer surface of the liquid-repelling cylinder 1 will be offset toward the outside to increase the spatial area that the liquid-repelling cylinder 1 can cover, so that the liquid-repelling cylinder 1 can be in an initial structural state that is always continuous when it is not used to clean the floor, so that any position on the outer surface of the liquid-repelling cylinder 1 will not appear in a state where it is always touched and pressed by the scraper 2 when the liquid-repelling cylinder 1 is not deformed and expanded, and at the same time, a contact and pressure structure is realized in which the scraper 2 can contact and apply pressure to the liquid-repelling cylinder 1 only when it is used to clean the floor, so that the liquid-repelling cylinder 1 can be in an initial structural state that is always continuous when it is not used to clean the floor to form a structure in which the scraper 2 does not touch and press the outer surface of the liquid-repelling cylinder 1.

[0084] In the present scheme, when the liquid-repellent cylinder 1 is not performing a rotational rolling motion, a first covering space area is formed in the rotational rolling direction, that is, when the liquid-repellent cylinder 1 is installed in place and is in an initial structural state, the cross-section of the liquid-repellent cylinder 1 in the radial direction or the rotational rolling direction forms a first covering space area, and the first covering space area and the scraper 2 are arranged to form a non-overlapping structure, so that the scraper 2 cannot contact the first covering space area or enter the first covering space area, and the scraper 2 cannot form a contact pressure on any position on the outer surface of the liquid-repellent cylinder 1. In this way, the liquid-repellent cylinder 1 can be in a continuous initial structural state when it is not used to clean the floor, so that any position on the outer surface of the liquid-repellent cylinder 1 will not appear in a state of being constantly touched and pressed by the scraper 2 when the liquid-repellent cylinder 1 is not deformed and expanded, which can effectively prevent the outer surface of the liquid-repellent cylinder 1 from being unable to recover its shape after deformation and being easily damaged due to being touched and pressed by the scraper 2 for a long time when the liquid-repellent cylinder 1 is not used to clean the floor.

[0085] Among them, when the liquid-repelling cylinder 1 performs a rotational rolling motion, a second covering space area is formed in the rotational rolling direction, that is, when the liquid-repelling cylinder 1 is installed in place and is in a moving state, the liquid-repelling cylinder 1 will deform and expand to form a cross-section in the radial direction or the rotational rolling direction to form a second covering space area, and at least a part of the scraper 2 is configured to be able to contact the second covering space area, so that the scraper 2 can contact the first covering space area or enter the first covering space area, at this time, the scraper 2 can form a contact pressure on the corresponding area position on the outer surface of the liquid-repelling cylinder 1, and form a concave structure of the scraping part 105, forming the scraping part 2 along the outer surface of the liquid-repelling cylinder 1 to scrape away the dirty liquid and dirt on the liquid-repelling cylinder 1, so that the liquid-repelling cylinder 1 can only be contacted and pressured by the scraper 2 when it is used to clean the floor, so that the liquid-repelling cylinder 1 can be in an initial structural state that is always continuous when it is not used to clean the floor to form a scraping part 2 that will not contact the liquid-repelling cylinder 1 The outer surface of the cylinder 1 is touched and pressed, and at least a part of the outer edge boundary of the second covering space area is arranged outside the outer edge boundary of the first covering space area. When the liquid-repellent cylinder 1 is deformed and expanded, the arc surface where the outer surface of the liquid-repellent cylinder 1 is located forms an outer edge boundary in the radial direction or the rotational rolling direction, so that at least a part of the outer edge boundary of the second covering space area formed by the liquid-repellent cylinder 1 under the deformation and expansion structure is located outside the outer edge boundary of the first covering space area formed by the liquid-repellent cylinder 1 in the initial structural state. At this time, when the liquid-repellent cylinder 1 is in a rotational and rolling motion, the outer edge boundary of the second covering space area will be contacted and pressed by the scraper 2 to form a concave structure of the scraping portion 105. The scraping portion 105 is formed by wrapping around or covering the outer surface of the scraper 2, thereby realizing effective scraping of the dirty liquid and dirt on the outer surface of the liquid-repellent cylinder 1, so that the liquid-repellent cylinder 1 can be kept in a clean and dry state, and the liquid-repellent cylinder 1 can be more easily cleaned.

[0086] In this solution, a water supply part can also be provided to supply clean water to the liquid-repelling cylinder 1. The clean water is supplied to the outer surface of the liquid-repelling cylinder 1 to form a structure of flow cleaning or flushing cleaning of the outer surface of the liquid-repelling cylinder 1. The structure of the liquid-repelling cylinder 1 and the structure of the scraper 2 make it easier to clean the liquid-repelling cylinder 1. At the same time, when the liquid-absorbing cylinder 3 is installed in place, clean water is supplied to the liquid-absorbing cylinder 3 to make the liquid-absorbing cylinder 3 wet to achieve a cleaning effect on the ground, and the scraper 2 is used to scrape off the dirty liquid and the dirt absorbed by the liquid-absorbing cylinder 3.

[0087] In the present scheme, when the liquid-repelling cylinder 1 has not deformed and expanded in the radial direction, a minimum distance value H0 is set from the outer surface of the area position on the liquid-repelling cylinder 1 corresponding to the position of the scraper 2 to the outer surface of the end position of the scraper 2, and H0 is greater than or equal to 0; that is, when the liquid-repelling cylinder 1 has not rotated and rolled, the liquid-repelling cylinder 1 has not deformed and expanded in the radial direction. Under this structure, a distance value is formed between the outer surface of the area position on the liquid-repelling cylinder 1 corresponding to the position of the scraper 2 and the outer surface of the end position of the scraper 2, wherein the minimum distance value H0 is greater than or equal to 0. When the minimum distance value H0 is equal to 0, the outer surface of the liquid-repelling cylinder 1 and the outer surface of the end position of the scraper 2 are in contact with each other, but do not constitute an implementation. The structure of the applied pressure, when the minimum distance value H0 is greater than 0, the outer surface of the liquid-repelling cylinder 1 and the outer surface of the end position of the scraper 2 are spaced apart, and the scraper 2 cannot contact the outer surface of the liquid-repelling cylinder 1. The outer surface of the liquid-repelling cylinder 1 will not form a structure that is touched and pressed in this case. At this time, the liquid-repelling cylinder 1 is in an initial structural state without deformation and expansion, so that the liquid-repelling cylinder 1 can be maintained in a structural state that is not touched and pressed, so that any position on the outer surface of the liquid-repelling cylinder 1 will not appear in a state of being touched and pressed by the scraper 2 when the liquid-repelling cylinder 1 is not deformed and expanded. This can effectively prevent the outer surface of the liquid-repelling cylinder 1 from being unable to recover its shape after deformation and being easily damaged due to long-term contact and pressure by the scraper 2.

[0088] In the present scheme, when the lyophobic cylinder 1 is deformed and expanded in the radial direction, the radius value R formed by the arc surface on which the outer surface of the lyophobic cylinder 1 is located is increased, and the expansion amount H formed by the increase is greater than or equal to 0.5 mm and less than or equal to 5 mm, and the expansion amount H is set to be greater than H0; that is, when the lyophobic cylinder 1 is rotating and rolling, the lyophobic cylinder 1 will deform and expand in the radial direction, and in the deformed and expanded state, the outer surface of the lyophobic cylinder 1 will be offset toward the outer side of the lyophobic cylinder 1, so that the scraper 2 can contact the outer surface of the lyophobic cylinder 1 and form a contact pressure structure for applying pressure. During the deformation and expansion, the lyophobic cylinder 1 will increase the radius value R formed by the arc surface on which the outer surface of the lyophobic cylinder 1 is located, and in the process of increasing, the radius value R will form a certain size. The expansion amount H is set to be greater than or equal to 0.5 mm and less than or equal to 5 mm to ensure that the liquid-repelling cylinder 1 can be formed into a contact and pressure structure by the scraper 2 under the deformed and expanded structure, so that the scraper 2 can form a relatively shallow scraping effect on the outer surface of the liquid-repelling cylinder 1 along the curved surface structure, and it is also ensured that the liquid-repelling cylinder 1 is prevented from being fatigued or damaged by excessive contact and pressure of the scraper 2. If the size of the expansion amount H is too large, the scraper 2 will excessively contact and press the outer surface of the liquid-repelling cylinder 1, and the excessive contact and pressure will reduce the deformation and rebound effect of the position on the outer surface of the liquid-repelling cylinder 1, which will make it difficult to reset the rebound deformation, and even easy to be damaged. At the same time, excessive contact and pressure will easily cause the liquid-repelling cylinder 1 to appear stuck and vibrate during the rotation and rolling motion, affecting the stability and reliability of the movement of the liquid-repelling cylinder 1.

[0089] In this scheme, the diameter value formed by the outer surface of the liquid suction cylinder 3 when it is not rotating and rolling is set to D1, and the diameter value formed by the cambered surface on which the outer surface of the liquid-repelling cylinder 1 is located when it is not rotating and rolling is set to D2. D1 is set to be greater than D2. In this case, that is, when the diameter value of the liquid suction cylinder 3 is greater than the diameter value of the liquid-repelling cylinder 1, when the liquid suction cylinder 3 is installed in place and does not rotate and roll, the liquid suction cylinder 3 can form an interference structure with the scraper 2, and when the liquid-repelling cylinder 1 is installed in place and does not rotate and roll, no contact pressure structure is formed between the liquid-repelling cylinder 1 and the scraper 2. At the same time, D1-D2 is set to be greater than or equal to 1 mm and less than or equal to 10 mm, or D1 is set to be greater than or equal to 1.1 times of D2 and less than or equal to 1.1 times of D2. The size limit is equal to 1.3 times of D2. Under this size limit, it can be ensured that the liquid-repelling cylinder 1 will not be pressed by the scraper 2 when it is not deformed and expanded, and it can be ensured that the liquid-repelling cylinder 1 can be pressed by the scraper 2 when it is deformed and expanded. Not only can the scraper 2 form a deep scraping effect on the liquid-absorbing cylinder 3 and improve the effect of scraping dirty liquid and dirt on the liquid-absorbing cylinder 3, but the scraper 2 can also form a relatively shallow scraping effect on the outer surface of the liquid-repelling cylinder 1 along the curved surface structure, preventing the liquid-repelling cylinder 1 from being fatigued or damaged by excessive contact and pressure of the scraper 2. If the contact and pressure are excessive, the deformation rebound effect of this position on the outer surface of the liquid-repelling cylinder 1 will be reduced, and then it will be difficult to reset the rebound deformation, and even easy to be damaged.

[0090] In the present scheme, when the scraping portion 2 forms a structure of contacting and pressing a part of the outer surface of the liquid-repelling cylinder 1, a scraping portion 105 is formed at a position on the outer surface of the liquid-repelling cylinder 1 where the scraping portion 2 contacts and applies pressure. Mainly, a part of the outer surface of the liquid-repelling cylinder 1 is recessed toward the inner side of the liquid-repelling cylinder 1, so that a scraping portion 105 with a recessed structure is formed at a position on the outer surface of the liquid-repelling cylinder 1 where the scraping portion 2 contacts and applies pressure. A part of the scraping portion 2 is located in the scraping portion 105 to form a structure of contacting the outer surface of the liquid-repelling cylinder 1 and applying pressure. A part of the scraping portion 2 is located in the scraping portion 105 to effectively form a structure for scraping dirty liquid and garbage from the outer surface of the liquid-repelling cylinder 1. When the liquid-repelling cylinder 1 rotates and rolls, the outer surface of the liquid-repelling cylinder 1 at different positions in the rotating and rolling direction successively forms a structure of being scraped. The scraping portion 2 has a structure of contacting and pressing, and sequentially forms a scraping portion 105, thereby sequentially scraping off dirty liquid and garbage at different positions on the outer surface of the liquid-repelling cylinder 1; and the area position on the outer surface of the liquid-repelling cylinder 1 where the scraping portion 105 is not formed is configured as a curved surface structure. When the scraping portion 2 does not form a structure of contacting and pressing the outer surface of the liquid-repelling cylinder 1, the area on the outer surface of the liquid-repelling cylinder 1 corresponding to the position of the scraping portion 2 is configured as a curved surface structure, so that the area does not constitute a recessed structure. A part or all of the outer surface of the liquid-repelling cylinder 1 has a curved surface structure and does not constitute a recessed structure, so that the outer surface of the liquid-repelling cylinder 1 is not easy to accumulate dirt and grime. At this time, the outer surface of the liquid-repelling cylinder 1 has a curved surface structure, so that it can be effectively cleaned, which is beneficial to remove and collect the dirty liquid and dirt on the outer surface of the liquid-repelling cylinder 1.

[0091] In the present scheme, when the scraping portion 2 does not form a contact pressure structure on the outer surface of the liquid-repelling cylinder 1 and the liquid-repelling cylinder 1 does not contact the ground, the outer surface of the liquid-repelling cylinder 1 is configured to be an integral arc surface structure in the rotation and rolling direction, so that there is no concave structure on the outer surface of the liquid-repelling cylinder 1, that is, when the liquid-repelling cylinder 1 is not deformed and expanded, no scraping portion 105 is formed on the liquid-repelling cylinder 1, and when the liquid-repelling cylinder 1 does not contact the ground, no dirt removing portion 106 is formed on the liquid-repelling cylinder 1. At this time, the outer surface of the liquid-repelling cylinder 1 is configured as an integral arc surface structure, that is, an integral annular arc surface structure, and there is no concave structure on the outer surface of the liquid-repelling cylinder 1. The overall arc surface structure makes the outer surface of the liquid-repelling cylinder 1 a structure that is not easy to hide dirt and grime, so that it can be effectively cleaned, which is conducive to removing and collecting dirty liquid and dirt on the outer surface of the liquid-repelling cylinder 1, and is not easy to cause secondary pollution to the ground.

[0092] In the present scheme, with respect to the specific structural part of the liquid-repellent cylinder 1, the liquid-repellent cylinder 1 includes an outer cylinder portion 101 and an inner cylinder portion 102, the outer cylinder portion 101 is located at the outer ring position of the inner cylinder portion 102, and the inner cylinder portion 102 is located at the inner ring position of the outer cylinder portion 101, and at the same time, the outer cylinder portion 101 and the inner cylinder portion 102 have a certain length value in the direction of the rotation axis to constitute their length structure, and the outer cylinder portion 101 and the inner cylinder portion 102 form a hollow structure spacer 104 in the radial direction, and the spacer 104 is mainly formed by surrounding the outer surface of the inner cylinder portion 102 and the inner surface of the outer cylinder portion 101, and the spacer 104 makes the outer cylinder portion 101 and the inner cylinder portion 102 in the radial direction. The structure is separated by intervals, and a plurality of intervals 103 are arranged in the interval area 104, and the intervals 103 are arranged to be connected to the outer cylinder part 101 and the inner cylinder part 102 respectively; the inner end of the interval 103 is connected to the outer surface of the inner cylinder part 102, and the outer end of the interval 103 is connected to the inner surface of the outer cylinder part 101, so that the interval 103 forms a connected structure between the outer cylinder part 101 and the inner cylinder part 102, and when the inner cylinder part 102 rotates and rolls, the plurality of intervals 103 drive the outer cylinder part 101 to perform a synchronous rotation and rolling motion structure, and at the same time, the inner cylinder part 102 forms a support for the outer cylinder part 101 through the plurality of intervals 103 The structure is provided in a rotational rolling direction to form a spacer 104 or a part of the spacer 104 between two adjacent spacers 103, and a spacer 103 is provided between two adjacent spacers 104, or a plurality of spacers 103 are provided to divide the spacer 104 into multiple parts to form a part of the spacer 104 between two adjacent spacers 103, wherein when the liquid-repelling cylinder 1 contacts the ground, a part of the outer surface of the liquid-repelling cylinder 1 is deformed toward the direction of the spacer 104 to form a decontamination portion 106 with a concave structure, and when the liquid-repelling cylinder 1 contacts the ground, it will be subjected to the pressure of the device body 100 so that a part of its outer surface is deformed toward the spacer 104. The partition 104 is deformed and recessed to form a dirt removal portion 106 with a recessed structure. The dirt removal portion 106 is configured to form a structure that drives dirty liquid and / or dirt to be transferred. The dirt removal portion 106 forms a scraping and cleaning effect on the ground to accommodate and drive the dirty liquid and / or dirt to be transferred. The dirt removal portion 106 and the scraping portion 105 are arranged in an interval distribution structure in the rotation and rolling direction, and the scraping portion 105 is arranged above the dirt removal portion 106, so that the scraping portion 105 is located above the dirt removal portion 106 to scrape the dirty liquid and garbage on the outer surface of the liquid-repelling cylinder 1, and part of the dirty liquid and garbage flows downward or falls in the scraped direction to be collected and processed.

[0093] In the present solution, when the liquid-repelling cylinder 1 contacts the ground, a portion of the outer surface of the liquid-repelling cylinder 1 is deformed toward the spacing area 104 to form a dirt-removing portion 106 with a concave structure. The dirt-removing portion 106 is configured to form a structure that drives dirt or a mixture of dirty liquid and dirt to be transferred. When the liquid-repelling cylinder 1 is located on the ground, the pressure of the machine body will cause a portion of the outer surface of the liquid-repelling cylinder 1 to be deformed toward the spacing area 104, thereby forming a dirt-removing portion 106 with a concave structure. The dirt-removing portion 106 is used to scrape the dirty liquid and garbage on the ground to collect the dirty liquid and garbage into the dirt-removing portion 106, and then drive and transfer them in the direction of rotation and rolling. When the dirt-removing portion 106 is separated from the ground, the dirt-removing portion 106 with a concave structure will rebound and reset to deform into a curved surface structure, and form an elastic force on the dirty liquid and garbage to achieve the effect of transferring and collecting the dirty liquid and garbage. During the continuous rotation and rolling motion of the liquid-repelling cylinder 1, different positions on the outer surface of the liquid-repelling cylinder 1 The dirt removing parts 106 are contacted with the ground respectively, and the dirt removing parts 106 with concave structures are formed in sequence. At the same time, the dirt removing parts 106 are formed in sequence in the direction of rotation and rolling, and the concave structures are formed to rebound and deform and return to the curved surface structure in sequence and in sequence. The whole process realizes the cleaning effect on the ground. At the same time, the depth of the concave formed by the dirt removing part 106 is set to be greater than the depth of the concave formed by the scraping part 105, so that the dirt removing part 106 has a deeper concave depth to accommodate the dirty liquid and garbage for driving and transferring, and the scraping part 105 has a relatively shallow concave depth to form the scraping part 2 to scrape the dirty liquid and garbage on the outer surface of the liquid-repelling cylinder 1, so as to achieve a better cleaning effect on the ground. The depth of the scraping part 105 formed when the scraping part 2 touches and presses the outer surface of the liquid-repelling cylinder 1 is relatively shallow, so as to form a better scraping along the curved surface structure on the outer surface of the liquid-repelling cylinder 1 to scrape the dirty liquid and garbage. At the same time, the outer surface of the liquid-repelling cylinder 1 can be prevented from being excessively worn or damaged, thereby improving the stability and reliability of the liquid-repelling cylinder 1.

[0094] Among them, the dirt removing part 106 is also a structure extending and distributed along the spacer part 103 in the direction of the rotation axis of the liquid-repellent cylinder 1. Mainly, the scraping part 2 is arranged to extend and distribute along the direction of the rotation axis of the liquid-repellent cylinder 1 to constitute its length structure in the direction of the rotation axis, and the spacer part 103 is also arranged to extend and distribute along the direction of the rotation axis to constitute its length structure in the direction of the rotation axis.

[0095] Optionally, the outer cylinder portion 101 and the inner cylinder portion 102 are both configured as a cylindrical or annular structure.

[0096] Optionally, the outer cylinder portion 101 is configured to be an annular or integral circular ring structure, so that the outer surface of the outer cylinder portion 101 is an integral annular structure when it is not in contact with the ground, that is, an integral curved ring structure.

[0097] In this solution, the depth of the depression formed by the scraping part 105 is set to be smaller than the interference depth formed by the scraping part 2 extending into the inner side of the outer surface of the liquid suction tube 3, and the depth of the depression formed by the scraping part 105 is set to be smaller than the depth of the depression formed by the dirt removal part 106, and the interference depth formed by the scraping part 2 extending into the inner side of the outer surface of the liquid suction tube 3 is set to be less than or equal to one half of D1; the depression depth of the scraping part 105 formed when the scraping part 2 touches and presses the outer surface of the liquid-repelling tube 1 is relatively shallow, so as to form a better scraping along the curved surface structure on the outer surface of the liquid-repelling tube 1 to scrape away dirty liquid and garbage, and at the same time, it can prevent the liquid-repelling tube 1 from being damaged. The outer surface is excessively worn or damaged, thereby improving the stability and reliability of the liquid-repelling cylinder 1; and realizing that the scraping part 2 forms an interference structure of relatively large depth on the liquid-absorbing cylinder 3, so as to realize a deep scraping structure for the liquid absorbed by the liquid-absorbing cylinder 3, realize effective scraping of the dirty liquid absorbed by the liquid-absorbing cylinder 3, and realize a deep scraping structure for the garbage clamped by the liquid-absorbing cylinder 3, which is beneficial to scrape the liquid-absorbing cylinder 3 for cleaning, reduce the secondary pollution of the liquid-absorbing cylinder 3 to the ground, and improve its working stability; at the same time, the jumping amplitude of the liquid-repelling cylinder 1 and the liquid-absorbing cylinder 3 when contacting the ground can be made smaller, thereby realizing a smaller noise generation.

[0098] Among them, the scraper 2 is arranged to extend into the inner side of the outer surface of the liquid suction cylinder 3 to form an interference depth less than or equal to one half of D1 to achieve a deep scraping effect on the liquid suction cylinder 3, which is beneficial to the deep scraping effect of the dirty liquid absorbed by the liquid suction cylinder 3 and the garbage carried by the liquid suction cylinder 3, thereby improving the effect of cleaning the liquid suction cylinder 3. At the same time, it can prevent the interference depth from being too large, which will cause resistance to the rotation and rolling movement of the liquid suction cylinder 3, prevent the liquid suction cylinder 3 from being stuck in movement, and improve the stability and safety of the movement of the liquid suction cylinder 3.

[0099] In the present scheme, when the liquid-repelling cylinder 1 is not deformed and expanded, the spacing distance value formed between the outer surface of the end position of the scraper 2 and the outer surface of the area position on the liquid-repelling cylinder 1 corresponding to the position of the scraper 2 is greater than or equal to 0 and less than or equal to half of the length distance value of the spacing portion 103 extending in the rotational rolling direction. It can be understood that when the spacing distance value is equal to 0, the end position of the scraper 2 is in contact with the outer surface of the liquid-repelling cylinder 1, but the scraper 2 does not apply pressure to the outer surface of the liquid-repelling cylinder 1, that is, the scraping portion 105 is not formed at this time. When the spacing distance value is greater than 0, the outer surface of the end position of the scraper 2 and the outer surface of the liquid-repelling cylinder 1 are spaced apart. That is, they are structures that do not contact each other; at the same time, the spacing distance value is limited to be less than or equal to half of the length distance value of the spacing part 103 extending in the rotational rolling direction to prevent the spacing distance between the outer surface of the end position of the scraper part 2 and the outer surface of the liquid-repellent cylinder 1 from being too large. If the spacing distance is too large, it may result in the liquid-repellent cylinder 1 being unable to form contact with the scraper part 2 and be pressed even if it performs a rotational rolling motion. The above-mentioned size limitation can effectively ensure that the scraper part 2 does not form a contact and pressure structure with the outer surface of the liquid-repellent cylinder 1 when the liquid-repellent cylinder 1 does not rotate and roll, and can effectively ensure that the scraper part 2 can form a contact and pressure structure with the outer surface of the liquid-repellent cylinder 1 when the liquid-repellent cylinder 1 performs a rotational rolling motion.

[0100] Or, in the present embodiment, the spacing distance value formed between the outer surface of the end position of the scraper portion 2 and the outer surface of the area position on the liquid-repelling cylinder 1 corresponding to the position of the scraper portion 2 is greater than or equal to 0 and less than or equal to twice the thickness value from the outer surface to the inner surface of the outer cylinder portion 101; it can be understood that when the spacing distance value is equal to 0, the end position of the scraper portion 2 is in contact with the outer surface of the liquid-repelling cylinder 1, but the scraper portion 2 does not apply pressure to the outer surface of the liquid-repelling cylinder 1, that is, the scraping portion 105 is not formed at this time; when the spacing distance value is greater than 0, the outer surface of the end position of the scraper portion 2 and the outer surface of the liquid-repelling cylinder 1 are spaced apart from each other, that is, they are not in contact with each other. structure; at the same time, the spacing distance value is limited to be less than or equal to twice the thickness value from the outer surface to the inner surface of the outer cylinder 101 to prevent the spacing distance between the outer surface of the end position of the scraper 2 and the outer surface of the liquid-repelling cylinder 1 from being too large. If the spacing distance is too large, it may result in the liquid-repelling cylinder 1 being unable to form contact with the scraper 2 and be pressed even if the liquid-repelling cylinder 1 is rotating and rolling. The above-mentioned size limitation can effectively ensure that the scraper 2 does not form a contact and pressure structure on the outer surface of the liquid-repelling cylinder 1 when the liquid-repelling cylinder 1 is not rotating and rolling, and can effectively ensure that the scraper 2 can form a contact and pressure structure on the outer surface of the liquid-repelling cylinder 1 when the liquid-repelling cylinder 1 is rotating and rolling.

[0101] In the present solution, the recessed depth of the scraping portion 105 is set to be greater than or equal to one third of the thickness value from the outer surface to the inner surface of the outer tube portion 101 and less than or equal to three times the thickness value from the outer surface to the inner surface of the outer tube portion 101. This can prevent the recessed depth of the scraping portion 105 from being too large, and achieve a relatively shallow depth of the scraping portion 105 formed when the scraping portion 2 touches and presses the outer surface of the liquid-repelling tube 1, thereby forming a better scraping along the curved surface structure on the outer surface of the liquid-repelling tube 1 to scrape away dirty liquid and garbage. At the same time, it can prevent the outer surface of the liquid-repelling tube 1 from being excessively worn or damaged, thereby improving the stability and reliability of the liquid-repelling tube 1.

[0102] Alternatively, in the present embodiment, the recessed depth of the scraping portion 105 is set to be greater than or equal to half of the thickness from the outer surface to the inner surface of the outer cylinder portion 101 and less than or equal to half of the length distance of the spacer portion 103 extending in the rotational rolling direction. This can prevent the recessed depth of the scraping portion 105 from being too large, and achieve a relatively shallow depth of the scraping portion 105 formed when the scraping portion 2 touches and presses the outer surface of the liquid-repelling cylinder 1, thereby forming a better scraping along the arc surface structure on the outer surface of the liquid-repelling cylinder 1 to scrape away dirty liquid and garbage. At the same time, it can prevent the outer surface of the liquid-repelling cylinder 1 from being excessively worn or damaged, thereby improving the stability and reliability of the liquid-repelling cylinder 1.

[0103] Or, in this scheme, the maximum interference depth value formed by the scraping portion 2 extending into the inner side of the outer surface of the liquid-absorbing cylinder 3 is H1, and the maximum depression depth value formed by the scraping portion 105 is H2, H1 is set to be greater than H2, and H1-H2 is set to be greater than or equal to 1 mm and less than or equal to 5 mm, so that the scraping portion 2 can form a deep scraping effect on the liquid-absorbing cylinder 3, and improve the effect of scraping dirty liquid and dirt on the liquid-absorbing cylinder 3. At the same time, the scraping portion 2 is used to form a relatively shallow scraping effect along the curved surface structure on the outer surface of the liquid-repelling cylinder 1, so as to prevent the liquid-repelling cylinder 1 from being fatigued or damaged by excessive contact and pressure of the scraping portion 2. If the contact and pressure are excessive, the deformation rebound effect of the position on the outer surface of the liquid-repelling cylinder 1 will be reduced, and then it will be difficult to reset the rebound deformation to restore to the initial shape structure, and it may even be easy to be damaged.

[0104] In this solution, the length distance value of the spacer 103 extending in the rotation and rolling direction is set to be greater than or equal to twice the thickness value from the outer surface to the inner surface of the outer cylinder 101 and less than or equal to the radius value of the arc surface on which the outer surface of the outer cylinder 101 is located, and the thickness value from the outer surface to the inner surface of the outer cylinder 101 is set to be greater than or equal to 0.4 mm and less than or equal to 1.4 mm; wherein the length distance value is used to form the length structure of the spacer 103 in the rotation and rolling direction, under which the spacer 103 can be deformed and expanded, and the thickness value from the outer surface to the inner surface of the outer cylinder 101 is used to form the outer cylinder 1 01 has a thickness structure in the radial direction. Under this thickness structure, the outer surface of the outer cylinder portion 101 can be effectively deformed and expanded, so that the outer surface of the outer cylinder portion 101 is offset toward the outside relative to the spacing portion 103 or the inner cylinder portion 102, so that a part of the outer surface of the outer cylinder portion 101 can contact the scraping portion 2 to form a pressed structure. At the same time, the thickness structure of the outer cylinder portion 101 enables a part of the outer surface of the outer cylinder portion 101 to be better deformed, so that it can be effectively deformed toward the spacing area 104 to better form a concave structure and thus achieve a better scraping and cleaning effect on the ground.

[0105] In the present solution, it can be understood that, regardless of whether the liquid-repelling cylinder 1 rotates and rolls and regardless of whether the liquid-repelling cylinder 1 cleans the ground, if the scraper 2 is always in a contact and pressure structure with the outer surface of the liquid-repelling cylinder 1, fatigue loss will occur at a certain position on the outer surface of the liquid-repelling cylinder 1, which will lead to the inability to effectively reset and rebound to the initial shape, that is, reset and rebound to the arc surface structure. If it continues for a long time, the problem of breakage will occur, resulting in a reduced service life and reliability of the liquid-repelling cylinder 1. In view of the use environment and characteristics of the surface cleaning machine, the surface cleaning machine generally works for about 20 minutes to 40 minutes, and is in a non-working state for most of the rest of the time. If the scraper 2 of the surface cleaning machine also forms a contact and pressure structure with the outer surface of the liquid-repelling cylinder 1 when the surface cleaning machine is not working, a certain position on the outer surface of the liquid-repelling cylinder 1 will be contacted and pressed for a long time to form a long-term concave structural state, which will lead to fatigue or even damage. If the contact and pressure are excessive, the deformation and rebound effect of the position on the outer surface of the liquid-repelling cylinder 1 will be reduced, and it will be difficult to reset and rebound the deformation to restore to the initial shape structure, and it may even be easy to break.

[0106] In the present solution, it can be understood that during the continuous rotation and rolling motion of the liquid-repelling cylinder 1, the position on the outer surface of the liquid-repelling cylinder 1 that contacts the scraper 2 is in a state of continuous change in the direction of the rotation and rolling motion, and there will not be a certain position on the outer surface of the liquid-repelling cylinder 1 that is continuously fixed and pressed by the scraper 2. Therefore, there will not be a problem that a certain position on the outer surface of the liquid-repelling cylinder 1 is fatigued and cannot recover its reset shape, and there will not be a problem that a certain position is damaged due to being continuously pressed by the scraper 2. This can better ensure that the outer surface of the liquid-repelling cylinder 1 has a better reset rebound deformation effect, thereby better cleaning the ground, and maintaining a better effect of scraping off dirty liquid and garbage between the scraper 2, thereby reducing secondary pollution to the ground.

[0107] In the present scheme, for the structural part of the liquid-repelling cylinder 1 that is deformed and expanded, the spacer 103 is set as a structure that can be deformed and expanded. When the liquid-repelling cylinder 1 rotates and rolls to form a throwing force, the spacer 103 is configured to be a structure that is deformed and expanded along its length direction, and then a part of the outer surface of the liquid-repelling cylinder 1 is configured as a contact pressure structure that is contacted and pressed by the scraping part 2; that is, the plurality of spacers 103 will be deformed and expanded along the length direction of the rotation and rolling direction or the radial direction of the liquid-repelling cylinder 1 under the action of the throwing force, so that a gap is formed between the outer surface of the inner cylinder 102 and the inner surface of the outer cylinder 101. The spacing space distance increases, that is, the spacing area 104 in the radial direction of the liquid-repellent tube 1 increases, and then the outer tube 101 will expand outward relative to the inner tube 102 as a whole under the deformation and expansion of the spacing part 103, so that the outer surface of the outer tube 101 is offset toward the outside of the liquid-repellent tube 1 to contact the scraper 2, and then the scraper 2 is formed into a contact pressure structure that contacts and applies pressure to the outer surface of the outer tube 101. At the same time, the outer surface of the outer tube 101 can effectively contact the ground to form a contact scraping cleaning structure that applies pressure, and can also improve the cleaning effect on the ground.

[0108] With regard to the structural portion for deformation and expansion of the spacer 103, the thickness of 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 of the spacer 103 enables the spacer 103 to be deformed and expanded stably and effectively under the action of the swinging force, thereby achieving the overall displacement of the outer cylinder 101 toward the outward direction, and realizing the effect of lifting the spacer 103 to deform and expand.

[0109] And / or, for the structural portion of the spacer 103 that is deformed and expanded, the length distance value of the spacer 103 extending in the rotational rolling direction is set to be greater than or equal to twice the thickness value of the spacer 103 in the rotational rolling direction, and the thickness value of the spacer 103 in the rotational rolling direction is set to be greater than or equal to 0.5 mm. The size limitation of the thickness value of the spacer 103 allows the spacer 103 to be stably and effectively deformed and expanded under the action of the swinging force. At the same time, the limitation of the length distance value of the spacer 103 allows the spacer 103 to be effectively deformed and expanded along its length direction, thereby achieving the overall displacement of the outer cylinder 101 toward the outward direction, and achieving the effect of lifting the spacer 103 to deform and expand.

[0110] In the present solution, the outer tube portion 101 is configured to be a deformable and expandable structure for the structural portion of the liquid-repelling tube 1 that is deformed and expanded. When the liquid-repelling tube 1 rotates and rolls to form a throwing force, at least a portion of the area on the outer surface of the outer tube portion 101 corresponding to the spacer 104 is configured to be deformed and expanded toward the outside of the liquid-repelling tube 1 under the action of the throwing force, thereby configuring a portion of the outer surface of the liquid-repelling tube 1 to be a contact pressure structure that is contacted and pressured by the scraping portion 2; that is, when the outer tube portion 101 is subjected to the throwing force, it will deform to form a deformable and expandable structure toward the outside of the liquid-repelling tube 1. The outer surface of the outer cylinder 101 is shifted toward the outside relative to the inner cylinder 102, mainly because a part of the outer surface of the outer cylinder corresponding to the spacer 104 is deformed and expanded toward the outside, so that a part of the outer surface of the outer cylinder 101 contacts the scraper 2, and forms a contact pressure structure that is contacted and pressured by the scraper 2. At this time, the scraper 2 can scrape off the dirty liquid and garbage adsorbed on the outer surface of the outer cylinder 101. At the same time, the outer surface of the outer cylinder 101 can effectively contact the ground to form a contact scraping cleaning structure that applies pressure, and can also improve the cleaning effect on the ground.

[0111] In the present solution, in order to improve the stability of the effective formation of the dirt removing part 106 and the dirt scraping part 105, and to improve the effective and stable deformation and expansion of the outer cylinder part 101, the arc length value formed by the area portion on the outer surface of the outer cylinder part 101 corresponding to the spacer area 104 in the rotational rolling direction is set to be greater than or equal to the minimum arc length value formed by the two adjacent spacers 103 in the rotational rolling direction. By limiting the size of the arc length value formed by the area portion on the outer surface of the outer cylinder part 101 corresponding to the position of the spacer area 104, it is ensured that the arc length value in this area portion of the outer cylinder part 101 in the rotational rolling direction has a moderate length. Under this arc length value, this area portion of the outer surface of the outer cylinder part 101 can be deformed and expanded toward the outside, thereby realizing the overall displacement of the outer cylinder part 101 toward the outside, and realizing that a part of the outer surface of the outer cylinder part 101 can contact the scraper part 2 to form a touched and pressed structure.

[0112] And / or, in order to improve the stability of the dirt removal part 106 and the dirt scraping part 105, and to improve the effective and stable deformation and expansion of the outer cylinder part 101, the thickness value from the outer surface to the inner surface of the outer cylinder part 101 is set to be less than or equal to the thickness value formed by the spacer part 103 in the rotation and rolling direction. By limiting the thickness value from the outer surface to the inner surface of the outer cylinder part 101, the thickness of the outer cylinder part 101 in the radial direction is limited. Under this thickness structure, the outer surface of the outer cylinder part 101 can be effectively deformed and expanded, and the outer cylinder part 101 can be effectively deformed and expanded. The outer surface of the cylinder 101 is offset toward the outside relative to the spacer 103 or the inner cylinder 102, so that a part of the outer surface of the outer cylinder 101 can contact the scraper 2 to form a pressed structure, and the spacer 103 is used to form an effective support for the outer cylinder 101, so that the inner cylinder 102 can drive the inner cylinder 102 to perform effective synchronous rotation and rolling motion through multiple spacers 103, and at the same time, the outer surface of the outer cylinder 101 is effectively formed to effectively form the dirt removal portion 106, thereby improving the effectiveness of the dirt removal portion 106 in being recessed.

[0113] In the present solution, a driving module is also provided on the machine body, and the driving module provides power to drive the liquid-repelling cylinder 1 and the liquid-absorbing cylinder 3 respectively. The driving module includes a motor and a driving gear assembly or a driving pulley assembly. The driving gear assembly or the driving pulley assembly can realize the docking of the liquid-repelling cylinder 1 or the liquid-absorbing cylinder 3 respectively. A docking part can be provided, and the liquid-repelling cylinder 1 and the liquid-absorbing cylinder 3 can be docked with the docking part respectively. When the liquid-repelling cylinder 1 is installed in place, the driving module realizes driving the liquid-repelling cylinder 1 to perform a rotational rolling motion. When the liquid-absorbing cylinder 3 is installed in place, the driving module realizes driving the liquid-absorbing cylinder 3 to perform a rotational rolling motion. Among them, at least a rotary motion for the liquid-repelling cylinder 1 to perform a rotational rolling motion is provided. The rotation speed V is greater than or equal to 250r / min and less than or equal to 950r / min. At this rotation speed, the liquid-repelling cylinder 1 can not only effectively contact the ground to form a better cleaning effect, but the liquid-repelling cylinder 1 can also better deform and expand in the radial direction, so that the scraper 2 can effectively form a contact and pressure structure on the outer surface of the outer cylinder 101. At the same time, at this rotation speed, the liquid-repelling cylinder 1 can be effectively prevented from excessively deforming and expanding in the radial direction, and the problem of excessive contact and pressure depth formed when the scraper 2 contacts and presses the outer surface of the outer cylinder 101 can be prevented, which can effectively prevent the outer cylinder 101 from being excessively contacted and pressed, resulting in excessive wear or damage.

[0114] Optionally, under the drive of the driving module, the rotation speed V of the rotational rolling motion of the liquid-repelling cylinder 1 is set to be greater than or equal to 250r / min and less than or equal to 950r / min, and the rotation speeds of the liquid-absorbing cylinder 3 and the liquid-repelling cylinder 1 for the rotational rolling motion are set to be the same rotation speed V. At this rotation speed, the liquid-repelling cylinder 1 can not only effectively contact the ground to form a better cleaning effect, but the liquid-repelling cylinder 1 can also better deform and expand in the radial direction, so that the scraper 2 can effectively form a contact and pressure structure on the outer surface of the outer cylinder 101. At the same time, at this rotation speed, the excessive deformation and expansion of the liquid-repelling cylinder 1 in the radial direction can be effectively prevented, and the problem of excessive contact and pressure depth formed when the scraper 2 contacts and presses the outer surface of the outer cylinder 101 can be prevented, which can effectively prevent the outer cylinder 101 from being excessively touched and pressed, resulting in excessive wear or damage. The problem that the outer cylinder 101 is excessively worn or damaged due to excessive contact and pressure is effectively prevented. The rotational rolling speeds of the liquid-repelling cylinder 1 and the liquid-absorbing cylinder 3 are set to be the same to form a rotational rolling motion with the same rotation speed V. It can be understood that at the same rotational rolling The squeegee 1 and the squeegee 3 are, therefore, not required to be controlled by the operator.

[0115] In the present scheme, preferably, the rotation speed V is set to be greater than or equal to 350r / min and less than or equal to 550r / min. At this rotation speed V, the liquid-repelling cylinder 1 can be deformed and expanded well to realize the scraping part 2 to scrape off the dirty liquid and dirt on the liquid-repelling cylinder 1, and at the same time, the dirt removal part 106 can be formed well to drive the dirty liquid and dirt on the ground to be transferred and collected, and the liquid suction cylinder 3 can be better to clean the ground and the dirty liquid and dirt are scraped off by the scraping part 2. At this rotation speed V, the stability of the liquid-repelling cylinder 1 and the liquid suction cylinder 3 is better, and the cleaning effect on the ground is better; at this rotation speed V, not only the scraping part 2 is effectively formed into a contact and pressure structure on the outer surface of the outer cylinder part 101, but also at the rotation speed V, the liquid-repelling cylinder 1 can be effectively prevented from excessively deforming and expanding in the radial direction, and the problem of excessive contact and pressure depth formed when the scraping part 2 contacts and presses the outer surface of the outer cylinder part 101 can be prevented, which can effectively prevent the outer cylinder part 101 from being excessively contacted and pressed, resulting in excessive wear or damage.

[0116] Alternatively, in this embodiment, at least the outer cylinder 101 is configured to be a structure composed of a liquid-repellent material so that the outer cylinder 101 does not absorb liquid, so that the outer surface of the outer cylinder 101 does not absorb dirty liquid during the cleaning process of contacting the ground. When the outer cylinder 101 contacts the ground, only the decontamination portion 106 is formed to accommodate and drive the transfer of dirty liquid and dirt. The outer cylinder 101 itself does not absorb dirty liquid, which is beneficial for the outer cylinder 101 to remain in a clean and dry state, thereby improving the collection effect of dirty liquid and garbage and reducing secondary pollution of the ground by the outer cylinder 101.

[0117] Alternatively, in the present embodiment, at least the outer cylinder 101 and the spacer 103 are both configured to be structures composed of a liquid-repellent material so that the outer cylinder 101 and the spacer 103 are both structures that do not absorb liquid, so that the spacer 103 can be effectively deformed without absorbing dirty liquid, and the outer surface of the outer cylinder 101 will not have a structure that absorbs dirty liquid during the process of contacting the ground for cleaning. When the outer cylinder 101 contacts the ground, only the decontamination portion 106 is formed to accommodate the dirty liquid and drive it to be transferred, and the outer cylinder 101 itself will not absorb the dirty liquid, which is beneficial for the outer cylinder 101 to remain in a clean and dry state, thereby improving the collection effect of dirty liquid and garbage and reducing the secondary pollution of the ground by the outer cylinder 101.

[0118] Optionally, in this solution, the entire lyophobic cylinder 1 can be made of lyophobic material, and the outer cylinder 101, the inner cylinder 102 and the plurality of spacers 103 are all made of lyophobic material, that is, hydrophobic material, to achieve a structure in which the lyophobic cylinder 1 does not absorb dirty liquid.

[0119] Or, in this scheme, a liquid absorbing layer 301 is provided on the liquid absorbing tube 3, and the liquid absorbing layer 301 is configured to be composed of a liquid absorbing material and has a soft and deformable structure so that the liquid absorbing layer 301 is configured to be a structure that absorbs liquid, and a scraper 2 is configured to extend into the liquid absorbing layer 301 to form a structure that interferes with each other, and the outer surface of the liquid absorbing layer 301 is configured to be the outer surface of the liquid absorbing tube 3, and the outer surface of the liquid absorbing layer 301 has a soft and deformable structure to achieve a scraping cleaning effect when contacting the ground, while absorbing dirty liquid and entraining dirt, and then driving the transfer for collection, and at the same time, the liquid absorbing layer 301 can absorb clean water, so that the clean water wets the liquid absorbing layer 301 and then scrapes the ground for cleaning effect, in this process, the scraper 2 contacts the liquid absorbing layer 301 to scrape off the dirty liquid absorbed by the liquid absorbing layer 301 and the entrained dirt, so as to achieve the combination of clean water to clean a part of the liquid absorbing layer 301, thereby improving the cleaning effect on the ground and reducing the secondary pollution of the liquid absorbing layer 301 to the ground.

[0120] Or, in the present scheme, when the liquid pipette cylinder 3 is deformed and expanded during the rotational rolling motion, the radius value R1 of the liquid pipette cylinder 3 increases and the increased expansion amount Y is less than 1 mm. Specifically, when the liquid pipette cylinder 3 is configured to be a deformable and expandable structure in its radial direction, the expansion amount of the liquid pipette cylinder 3 that can be deformed and expanded is smaller than the expansion amount of the liquid-repellent cylinder 1 that can be deformed and expanded. The radius value R1 of the liquid pipette cylinder 3 will increase during the deformation and expansion process, but the increased expansion amount Y is smaller than the expansion amount of the liquid-repellent cylinder 1 when it is deformed and expanded, and is less than 1 mm. This can effectively prevent the scraper 2 from forming an interference depth in the interference structure of the liquid pipette cylinder 3 that is too large, and prevent the liquid pipette cylinder 3 from having excessive resistance to the rotational rolling motion, resulting in motion jamming or motion vibration, thereby achieving the effect of lifting the scraper 2 to scrape away dirty liquid and dirt on the liquid pipette cylinder 3 to improve the stability of the movement of the liquid pipette cylinder 3.

[0121] Or, in the present scheme, when the liquid suction cylinder 3 is installed in place and does not perform a rotational rolling motion, the scraper portion 2 is configured to be in contact with the liquid suction cylinder 3 and when the liquid suction cylinder 3 and the liquid-repelling cylinder 1 are installed in place respectively, it is configured to be able to rotate and roll around the same rotation axis; wherein, when the liquid suction cylinder 3 is installed in place and does not perform a rotational rolling motion or performs a rotational rolling motion, it is configured to be in contact with the scraper portion 2 to form a contact and pressure structure for the liquid suction cylinder 3, because the liquid suction cylinder 3 is to absorb dirty liquid, the liquid suction cylinder 3 will not be designed with a spacing area 104 like the liquid-repelling cylinder 1, so that even if the scraper portion 2 continues to contact the liquid suction cylinder 3 and applies pressure, the problem that the liquid suction cylinder 3 cannot restore its shape will not occur; wherein, when the liquid suction cylinder 3 and the liquid-repelling cylinder 1 are installed in place interchangeably, the two are installed in the same docking position when they are independently installed in place to realize that they rotate and roll around the same rotation axis respectively and independently, and the structure of promoting the mutual replacement of the two is simpler, and the adaptability of the mutual replacement is better, which is convenient for users to carry out interchangeable operations.

[0122] It can be seen that in the present scheme, the same scraper 2 can be used to scrape away dirty liquid and garbage from the liquid-repelling cylinder 1 and the liquid-absorbing cylinder 3 respectively, and there is no need to set up multiple scrapers 2 to respectively adapt to the liquid-repelling cylinder 1 and the liquid-absorbing cylinder 3 to scrape away dirty liquid and garbage, so that the overall structure is simple and the cost is lower. In addition, the same scraper 2 has better adaptability to the liquid-repelling cylinder 1 and the liquid-absorbing cylinder 3, and has better effects in scraping away dirty liquid and garbage respectively, which can effectively prevent the liquid-repelling cylinder 1 or the liquid-absorbing cylinder 3 from secondary pollution of the ground.

[0123] In this solution, the liquid-repellent material is a hydrophobic material. The outer cylinder 101 or the liquid-repellent cylinder 1 composed of the hydrophobic material will not absorb dirty liquid, that is, sewage, nor will it absorb clean water, so that sewage and dirt, that is, garbage, can only adhere to the outer surface of the outer cylinder 101, and will not be absorbed by the outer cylinder 101, so that the outer cylinder 101 can be effectively maintained in the curved surface structure, which is convenient for scraping off sewage and garbage from the outer cylinder 101 to keep it in a clean and dry state, without the need to set a drying mechanism for drying or air drying. The overall structure is simple, the cost is low, and the cleaning effect on the ground is good; at the same time, the liquid-repellent cylinder 1 composed of the hydrophobic material can form a flow cleaning or flushing cleaning effect by supplying clean water to the outer surface of the liquid-repellent cylinder 1. Combined with the curved surface structure of the outer surface of the liquid-repellent cylinder 1 and the structure that is not easy to hide dirt and grime, it is achieved that the outer surface of the liquid-repellent cylinder 1 can be simply cleaned, and the outer surface of the liquid-repellent cylinder 1 after cleaning is continuously in contact with the ground for cleaning.

[0124] In this solution, the liquid-absorbing material is a water-absorbing material, such as cloth material, fluff material, sponge material, etc. The liquid-absorbing tube 3 or liquid-absorbing layer 301 composed of the water-absorbing material can effectively absorb sewage on the ground and carry garbage to clean the ground.

[0125] In this solution, the surface cleaning equipment can be a handheld structure or a self-moving structure; such as a handheld floor scrubber, a handheld floor mop, etc. If it is a self-moving cleaning robot, a self-moving floor scrubbing robot, etc., the corresponding structures such as the liquid-repelling cylinder 1 and the liquid suction cylinder 3 in this solution can be set.

[0126] Working principle: The surface cleaning device of this scheme is provided with a liquid-repelling cylinder 1 and a liquid-absorbing cylinder 3. The liquid-repelling cylinder 1 and the liquid-absorbing cylinder 3 are arranged to be interchangeable. The user can choose the liquid-repelling cylinder 1 to be installed in place to achieve a cleaning effect on the ground without absorbing dirty liquid, or can choose the liquid-absorbing cylinder 3 to achieve a cleaning effect on the ground in a state where the ground absorbs dirty liquid, so that the surface cleaning device has a multifunctional use effect; at the same time, a scraping part 2 is provided, and when the liquid-repelling cylinder 1 is not deformed and expanded, the scraping part 2 will not form a scraping and pressing structure on the liquid-repelling cylinder 1, and when the liquid-repelling cylinder 1 is deformed and expanded, the scraping part 2 can form a scraping and pressing structure on the liquid-repelling cylinder 1, thereby effectively preventing the liquid-repelling cylinder 1 from being continuously touched and pressed by the scraping part 2. , which can effectively prevent the problem that the lyophobic cylinder 1 cannot effectively rebound to restore its shape, improve the safety and reliability of the lyophobic cylinder 1, and prevent the lyophobic cylinder 1 from being damaged; at the same time, the lyophobic cylinder 1 can effectively form the cleaning portion 106 when it contacts the ground, and the cleaning portion 106 can form a scraping and cleaning effect on the ground, so that the dirty liquid and dirt on the ground can be accommodated and then driven to be transferred. At the same time, the outer surface of the lyophobic cylinder 1 can continuously switch between a concave structure and a curved surface structure, forming a concave structure by contacting the ground and restoring the curved surface structure by not contacting the ground, so that the lyophobic cylinder 1 can be effectively kept in a clean and dry state, reducing secondary pollution to the ground and improving the cleaning effect on the ground.

[0127] Those skilled in the art will appreciate that the above-mentioned embodiments are specific examples for realizing the present invention, and in actual applications, various changes may be made in form and detail without departing from the spirit and scope of the present invention, all of which are within the protection scope of the present invention.
