Description

Technical Field

[0002] The existing cleaning machines are mainly used to achieve the cleaning effect of the ground. Among them, a cloth roller structure or a rubber roller structure is mainly provided to perform contact cleaning on the ground. For the rubber roller structure, it mainly realizes the cleaning effect of the ground by deforming the rubber roller when it contacts the ground, and at the same time, it drives the dirty liquid and garbage to be transferred when cleaning the ground through the recovery and rebound after deformation. However, after the rubber roller has been used for a period of time, the deformation effect of the rubber roller will deteriorate, and the effect of rebounding and restoring the shape will also deteriorate, which will lead to a reduction in the cleaning effect of the rubber roller on the ground, and it is easy to cause secondary pollution on the ground by residual dirty liquid and garbage, which seriously affects the user's use of the cleaning machine.

[0045] Alternatively, when a liquid supply portion is provided to clean the cleaning portion, the position where the liquid provided by the liquid supply portion enters the outer surface of the cleaning portion is located at a position on the outer surface of the cleaning portion where the curved surface structure is formed.

[0046] Compared with the prior art, the present invention has the following beneficial effects:

[0047] In this solution, the cleaning component achieves the cleaning effect on the ground, wherein the cleaning part can achieve the cleaning effect on the ground by deformation, and can be deformed between a curved surface structure and a recessed structure. When it is a curved surface structure, the cleaning part can be effectively cleaned, is not easy to hide dirt and grime, and is not easy to cause secondary pollution to the ground. When it is a recessed structure, the cleaning part can accommodate dirty liquid and garbage on the ground to achieve the cleaning effect of the ground through the recessed structure. The cleaning part as a whole is not easy to hide dirt and grime, and the cleaning part can be kept in a better clean and dry state, and has a better cleaning effect on the ground.

[0048] In this solution, a resilient portion is provided on the inner side of the cleaning portion, and the resilient portion forms a filling and covering structure in the rotational rolling direction and the radial direction. The resilient portion can form an elastic structure in the radial direction, and then can form an elastic driving force when the cleaning portion rebounds to its shape after deformation, thereby lifting the cleaning portion to rebound and restore its shape.

[0049] In this solution, by setting up the rebound part, an active elastic driving force can be effectively provided for the rebound and shape recovery of the cleaning part, so that the cleaning part can rebound and restore its shape under passive force, which greatly improves the stability and reliability of the rebound and shape recovery of the cleaning part.

[0050] In this solution, the structural setting of the resilient part enables the resilient part to form an auxiliary cleaning part to rebound and restore the shape, which can reduce the situation where the cleaning part relies solely on its own soft deformation structure to rebound, thereby improving the cleaning part's ability to maintain a better rebound effect for a longer period of time, reducing the aging speed of the cleaning part's deformation effect, and improving the stability and reliability of the cleaning part's deformation and rebound, thereby improving the cleaning effect on the ground and reducing secondary pollution to the ground.

[0051] The structural setting of the resilient part of this scheme enables the resilient part to effectively form elastic deformation in the radial direction and thus generate elastic driving force to form a certain amount of elasticity. At the same time, it can effectively drive the cleaning part to perform synchronous rotational rolling motion in the rotational rolling direction, thereby driving the cleaning part to effectively contact the ground and deform to clean the ground, thereby improving the stability and reliability of the cleaning part in cleaning the ground. At the same time, the cleaning part has a better cleaning effect on the ground.

[0052] The structural setting of the first touch-changing part or the second touch-changing part of this solution enables the cleaning part to deform along the first touch-changing part or the second touch-changing part when it contacts the ground in the rotational rolling direction, thereby effectively forming a concave structure. By cleaning the ground through the concave structure, it can be ensured that the cleaning part can be stably and effectively deformed to form a concave structure.

[0053] In this solution, the structural setting between the resilient part and the cleaning part enables the resilient part to not only effectively drive the cleaning part to perform synchronous rotational rolling motion, preventing the cleaning part from independently rolling in the rotational rolling direction relative to the resilient part, but also form the resilient part to effectively assist the cleaning part to make the concave structure deform and rebound to restore to the arc surface structure, thereby improving the driving and transferring effect of dirty liquid and garbage, thereby improving the cleaning effect of the ground, and effectively reducing the secondary pollution of the cleaning part to the ground.

[0054] In this solution, by setting a hole structure or a pit structure on the resilient part, not only the deformation effect of the resilient part can be effectively improved, but also the effect of the resilient part in providing elastic driving force can be effectively improved. In the process of forming a recessed structure in the cleaning part, the resilient part can be better compressed and deformed, and when the recessed structure of the cleaning part deforms and rebounds to restore to the arc surface structure, the resilient part can better improve the elastic driving force.

[0055] In this solution, the specific structural part of the hole structure or the pit structure can effectively enhance the deformation effect of the resilient part, and at the same time effectively enhance the elasticity of the resilient part in the radial direction, thereby enhancing the effect of the resilient part in providing elastic driving force, thereby achieving better elastic propulsion for the cleaning part to rebound from the deformation of the concave structure to the arc surface structure.

[0056] In this solution, the structural part of the re-elastic part enables the re-elastic part to have better reliability and stability while having an elastic structure, and can provide elastic driving force in the radial direction stably and reliably. At the same time, it can have a better filling and covering structural effect in the rotational rolling direction, and realize the synchronous rotation and rolling motion of the cleaning part, so that the re-elastic part is not easy to break or damage in the rotational rolling direction, and can effectively maintain a continuous filling and covering structural effect.

[0057] The structure of the cleaning part of this solution enables the cleaning part to have just the right wear-resistant effect to contact the ground to form a scraping cleaning effect, and to form a concave structure by scraping to clean the ground. At the same time, the structure of the resilient part can effectively form an elastic driving force, and the resilient part can effectively form a filling and covering structure so that the outer surface of the cleaning part maintains a full arc structure or a plump arc structure when no external force is applied, so that the outer surface of the cleaning part can stably maintain a good rebound and shape recovery effect.

[0074] In order to make the technical means, creative features, objectives and effects achieved by the present invention easier to understand, the present invention is further described below in conjunction with specific embodiments.

[0075] Embodiment: The cleaning machine system of the present invention is as follows Figure 1 to Figure 1 As shown in the structure, the cleaning machine system mainly includes a cleaning machine, which realizes the cleaning effect of the ground. Among them, the cleaning machine is mainly provided with a cleaning component 2, which realizes the cleaning effect of the ground. At the same time, the cleaning part 20 on the cleaning component 2 can effectively rebound and then recover to the arc surface structure before deformation, and form a long-term and reliable rebound and recovery shape effect through the elastic driving force of the rebound part 30, thereby realizing that the cleaning part 20 can effectively clean the ground for a long time, improve the cleaning effect of the ground, effectively drive the transfer of dirty liquid and garbage, greatly reduce the secondary pollution of dirty liquid and garbage to the ground, and thus improve the user experience of using the cleaning machine.

[0076] The cleaning machine system of this solution includes a cleaning machine, which is provided with a machine body 1, that is, it includes the machine body 1. The machine body 1 is mainly used to move on the ground to achieve a cleaning effect on the ground. The cleaning machine also includes a cleaning component 2, and the cleaning component 2 is configured to be installed on the machine body 1 to clean the ground. When the machine body 1 moves on the ground, the cleaning effect of the ground is achieved through the cleaning component 2.

[0077] Among them, the structural part of the cleaning component 2 is provided with a cleaning part 20 on the cleaning component 2. The cleaning part 20 is set to a soft and deformable structure, and the cleaning part 20 is also set to a hydrophobic structure that does not absorb liquid. The cleaning part 20 is mainly set to an annular structure. When the cleaning part 20 is not deformed, the cleaning part 20 can be an overall annular structure, mainly a hollow annular structure. The cleaning part 20 can effectively deform under the soft and deformable structure to achieve the cleaning effect of the ground through deformation. At the same time, the cleaning part 20 does not absorb liquid in the process of cleaning the ground. Instead, it accommodates part of the liquid or garbage through deformation to drive and transfer to achieve the cleaning effect of the ground, so that the cleaning part 20 itself does not absorb liquid, and its own weight does not become heavier due to the absorption of liquid. It does not hide dirt and grime due to the absorption of liquid or the entrainment of garbage. Some liquid or dirt will adhere to the outer surface of the cleaning part 20, but will not be absorbed into the inside of the cleaning part 20. This makes the cleaning part 20 extremely easy to clean and can be better kept in a clean and dry state.

[0078] Among them, the specific structural part is that at least a part of the outer surface of the cleaning portion 20 is set to be an cambered surface structure, which is mainly composed of an cambered surface structure in the rotation and rolling direction, and is mainly composed of an arc surface structure. When the cleaning portion 20 is not deformed, it can be constituted as an integral annular structure, that is, a continuous cambered surface structure is constituted as an annular structure in the annular direction, so that the cleaning portion 20 can perform a rotational rolling motion in the annular direction to achieve the cleaning effect of the ground. At the same time, the setting of the cambered surface structure enables the cleaning portion 20 to be better deformed to clean the ground, and at the same time, makes the cleaning portion 20 easier to clean; in the process of the cleaning portion 20 cleaning the ground, when the outer surface of the cleaning portion 20 contacts the ground, it can be formed that at least a part of the outer surface of the cleaning portion 20 is radially toward the cleaning portion 20. The arc surface structure is deformed and recessed upward to form a recessed structure. When the cleaning part 20 rotates and rolls, a structure for cleaning the ground is formed through the recessed structure. When the outer surface of the cleaning part 20 contacts the ground, it will be subjected to pressure due to the gravity of the machine body 1. At this time, a part of the arc surface structure on the outer surface of the cleaning part 20 will be deformed toward the inside. During the deformation process, the arc surface structure is deformed into a recessed structure. Combined with the rotating and rolling motion of the cleaning part 20, the ground is rubbed and scraped to clean, so that part of the dirty liquid and garbage are accommodated in the recessed structure. During the rotating and rolling motion of the cleaning part 20, the dirty liquid and garbage in the recessed structure are driven to be transferred along the rotating and rolling direction, thereby achieving the collection effect of the dirty liquid and garbage, and thus achieving the cleaning effect of the cleaning part 20 on the ground.

[0079] It is understandable that, based on the understanding of the prior art, a sewage suction channel can also be provided on the machine body 1, one side of the sewage suction channel is open toward the outer surface of the cleaning part 20 and forms a connecting structure with the ground, and the other end of the sewage suction channel is finally connected to the airflow device. Under the operation of the airflow device, the airflow is realized to flow from the ground into the outer surface of the cleaning part 20, so that the airflow drives the dirty liquid and garbage on the ground and the dirty liquid and garbage moved by the cleaning part 20 are sucked into the sewage suction channel, and then the dirty liquid and garbage are sucked into the sewage tank by the suction force of the airflow, and the combination of the airflow device and the cleaning part 20 can achieve better collection and treatment of dirty liquid and garbage.

[0080] In this solution, in order to enhance the effect of the concave structure to rebound and restore its shape, and to achieve the effect of transferring dirty liquid and garbage, a resilient part 30 with an elastic structure is also provided on the cleaning component 2. The resilient part 30 can be better compressed when subjected to the pressing force, and at the same time form an elastic effect, and can better form an elastic driving force when the pressing force disappears. Specifically, the resilient part 30 is set to be located on the inner side of the cleaning part 20 in the radial direction to form a filling and covering structure in the radial direction and the rotational rolling direction, mainly in the radial direction from the inner surface of the cleaning part 20 toward the inside to fill and cover, and form a filling and covering structure along the rotational rolling direction, and finally form a filling and covering structure of a certain area, and the filling and covering length of the resilient part 30 in the rotational rolling direction is set to be greater than the filling and covering length in the radial direction, so that the resilient part 30 can better cooperate with the cleaning part 20 in the rotational rolling direction to deform to clean the ground through the concave structure, so that the cleaning part 20 has a longer filling and covering area in the rotational rolling direction to pass The ground is cleaned through the recessed structure. At the same time, when the recessed structure on the cleaning part 20 is deformed and restored to the arc surface structure, the re-elastic part 30 is set to form a structure that contacts the cleaning part 20 and forms a structure for applying an elastic driving force to the cleaning part 20. This is mainly because when the corresponding recessed structure area of ​​the cleaning part 20 is separated from the ground during the rotation and rolling motion, it will be deformed under the soft structure of the cleaning part 20 itself to rebound and restore its shape. At the same time, the corresponding area on the re-elastic part 30 is no longer subjected to the pressing force. At this time, it will elastically deform from the compressed state to the natural state and thus form an elastic driving force on the recessed structure, that is, it can effectively form an elastic driving force on the cleaning part 20 in the radial direction, so that the recessed structure rebounds to restore its shape to the arc surface structure. Under the arc surface structure, the outer surface of the cleaning part 20 can be effectively cleaned, and at the same time, in the process of rebounding to restore the shape, it will form a push on the dirty liquid and garbage to achieve the effect of driving the transfer and collection. It can be seen that the structural setting of the re-elastic part 30 can effectively improve the effect and efficiency of the recessed structure to rebound and restore its shape.

[0081] Preferably, the resilient portion 30 is configured to be annular in shape along the direction of rotation and rolling, and to constitute a continuous and uninterrupted filling and covering structure in the direction of rotation and rolling, forming an overall filling and covering area in the annular direction, so that it can better cooperate with the cleaning portion 20 to achieve that any position of the outer surface of the cleaning portion 20 in the direction of rotation and rolling can effectively constitute a recessed structure, and can effectively form a recessed structure to effectively rebound and restore its shape under the elastic driving force of the resilient portion 30, thereby improving the effect and efficiency of the cleaning portion 20 in restoring the arc surface structure, and improving the effect of transferring dirty liquid and garbage contained in the recessed structure. When the recessed structure rebounds and restores its shape, it can restore its shape more stably and effectively under the elastic driving force of the resilient portion 30, and is less likely to have problems such as slow rebound and rebound failure.

[0082] In this solution, a first space area 40 with an annular structure and a hollow structure is mainly provided on the inner side of the cleaning part 20, that is, the hollow area of ​​the hollow structure of the cleaning part 20 is used to form the first space area 40, and the resilient part 30 is provided in the first space area 40 to form a filling and covering structure along the radial direction and the rotation and rolling direction. The resilient part 30 is installed in the first space area 40, and a filling and covering structure is formed along the radial direction and the rotation and rolling direction of the first space area 40, that is, the annular direction, so that the cleaning part 20 is covered on the outside of the resilient part 30, and the resilient part 30 is located in the first space area 40. The filling and covering support structure is formed on the inner side of the cleaning portion 20, and the cleaning portion 20 is made to have a full cambered surface structure under the filling support structure of the resilient portion 30, or it can be formed into a full overall annular structure, so that the cleaning portion 20 can have a full cambered surface structure when it is not in contact with the ground for deformation, so that the cleaning portion 20 can effectively improve its soft and deformable performance; wherein the resilient portion 30 is set to have an annular structure and the resilient portion 30 is set to have an elastic structure at least in the radial direction, thereby forming a resilient portion 30 that can radially deform the cleaning portion 20. The cleaning portion 20 is structured to apply an elastic driving force, forming a resilient portion 30 to fill and cover the first space area 40 in the annular direction and form a filling and covering structure in the radial direction. The elastic structure of the resilient portion 30 enables it to form an elastic driving force in the radial direction. In the radial direction, the recessed structure of the cleaning portion 20 can form a crimping structure on the resilient portion 30 in the radial direction so that the resilient portion 30 is compressed. When the recessed structure does not form a crimping structure, the resilient portion 30 can contact the recessed structure in the radial direction and generate an elastic driving force. At this time, the resilient portion 30 is deformed and recovered by the compression structure to expand to a natural state. During this process, an elastic driving force is generated to deform the concave structure and rebound to restore its shape to a curved surface structure, so that the rebound part 30 can form an auxiliary cleaning part 20 to rebound and restore its shape. This can reduce the situation where the cleaning part 20 relies solely on its own soft deformation structure to rebound, thereby improving the cleaning part 20 to maintain a better rebound effect for a longer period of time, reducing the deformation effect of the cleaning part 20 and the aging speed of the deformation performance, and improving the stability and reliability of the cleaning part 20 in deformation and rebound.

[0083] In this solution, in order to further enhance the elastic driving force of the resilient portion 30 on the cleaning portion 20 and the effect of the resilient portion 30 driving the cleaning portion 20 to perform synchronous rotation and rolling motion, the elastic amount of deformation of the resilient portion 30 in the radial direction is set to be greater than or equal to the elastic amount of deformation in the rotation and rolling direction, so that the resilient portion 30 has a larger elastic space in the radial direction to achieve a larger elastic amount, so that the resilient portion 30 can have a larger distance of elasticity in the radial direction, and the concave structure on the cleaning portion 20 can be enhanced to press the resilient portion 30 so that the resilient portion 30 is compressed, and at the same time, the effect of the resilient portion 30 deforming from the compressed state to expand to generate an elastic driving force is enhanced, so that the concave structure is effectively deformed and rebounded to restore its shape; at the same time, a relatively small elastic amount in the rotation and rolling direction is provided so that The re-elastic portion 30 can stably drive the cleaning portion 20 to perform synchronous rotation and rolling in the rotational rolling direction. It can be understood that when the elastic amount of the re-elastic portion 30 in the rotational rolling direction is large, it is easy for the re-elastic portion 30 and the cleaning portion 20 to be misaligned in the rotational rolling direction, that is, the re-elastic portion 30 can only drive the cleaning portion 20 to perform synchronous rotation and rolling motion after rotating a certain angle during rotation and rolling. It can be seen that by setting the elastic amount of deformation of the re-elastic portion 30 in the radial direction to be greater than or equal to the elastic amount of deformation in the rotational rolling direction, the re-elastic portion 30 can promptly drive the cleaning portion 20 to perform synchronous rotation and rolling motion in the direction of rotation and rolling, thereby improving the elastic driving force of the re-elastic portion 30 on the cleaning portion 20 and the effect of the re-elastic portion 30 driving the cleaning portion 20 to perform synchronous rotation and rolling motion.

[0084] And / or, in order to further enhance the elastic driving force of the resilient portion 30 on the cleaning portion 20 and the effect of the resilient portion 30 driving the cleaning portion 20 to perform synchronous rotational rolling motion, the elastic structure of the resilient portion 30 is configured in the radial direction to have a softer elasticity relative to the rotational rolling direction, so that the resilient portion 30 can have a softer structure in the radial direction, and then can be effectively deformed in the radial direction, which is beneficial to the formation of the concave structure on the cleaning portion 20, and is also beneficial to the rebound and shape recovery of the concave structure on the cleaning portion 20; it can be understood that in the radial direction, when the cleaning portion 20 is deformed to form a concave structure, a crimping effect is formed on the resilient portion 30, causing the resilient portion 30 to be compressed, and under the structure that the resilient portion 30 has a softer radial direction, it can be achieved The resilient portion 30 is more easily compressed to cooperate with the cleaning portion 20 to deform and concave, thereby improving the effect of the concave structure formation; and when the resilient portion 30 forms an elastic driving force, the resilient portion 30 has a softer structure in the radial direction, which can enable the resilient portion 30 to better rebound and generate an elastic driving force, thereby achieving the effect of the concave structure rebounding and recovering to the arc shape; the resilient portion 30 has a harder structure in the rotational rolling direction relative to the radial direction, so that the resilient portion 30 can better form a continuous filling and covering structure in the rotational rolling direction, so that the resilient portion 30 is not easy to break or damage in the rotational rolling direction due to the rotational force, thereby improving the stability and reliability of the resilient portion 30 in the rotational rolling direction to drive the cleaning portion 20 to perform synchronous rotational rolling motion.

[0085] In this solution, in order to better guide the formation of the recessed structure, prevent the recessed structure on the cleaning portion 20 from being difficult to form or prevent the recessed structure on the cleaning portion 20 from having a poor cleaning effect on the floor due to a too small depth of the recessed structure; this solution is provided with a plurality of first contact-changing portions 50 in a convex structure on the inner surface of the cleaning portion 20 and / or the outer surface of the resilient portion 30, and the plurality of first contact-changing portions 50 are arranged to be spaced apart in the direction of rotation and rolling and a single first contact-changing portion 50 is arranged to be extended along the direction of the rotation axis; the single first contact-changing portion 50 is mainly on the inner surface of the cleaning portion 20 and the outer surface of the resilient portion 30. The outer surfaces are convex, and a single first contact-changing portion 50 is also formed as an extended structure along the rotation axis, which is the length structure of the first contact-changing portion 50. At the same time, multiple first contact-changing portions 50 are spaced apart in the rotation and rolling direction. The structure of the first contact-changing portion 50 is mainly formed so that when the cleaning portion 20 contacts the ground, the arc surface structure on its outer surface is guided and deformed in the annular direction by the position of the first contact-changing portion 50 in the rotation and rolling direction to form a concave structure for cleaning the ground. It can be understood that when the cleaning portion 20 contacts the ground for rotation and rolling, when the first contact-changing portion 50 is radially When the corresponding position on the cleaning part 20 contacts the ground in the direction, the friction force generated in the contact with the ground will be increased. Under the structure of increased friction, the arc surface structure part on the outer surface of the cleaning part 20 will be guided and deformed in the annular direction to form a concave structure for cleaning the ground. The formation of the concave structure starts from the corresponding position of the first contact-changing part 50 on the cleaning part 20, and then gradually concaves in the direction opposite to the rotation and rolling direction along the annular direction to form a concave structure, until it reaches the corresponding position of the next first contact-changing part 50 on the cleaning part 20, realizing the formation of a single concave structure. The cleaning effect on the ground is formed during the formation process; that is, a single concave structure is formed between two adjacent first contact-changing parts 50 in the rotational rolling direction or the annular direction, that is, a single concave structure is formed between two adjacent first contact-changing parts 50. In the process of continuous rotation and rolling of the cleaning part 20, concave structures are formed in sequence between two adjacent first contact-changing parts 50 at different positions in the rotational rolling direction, and then sequential concave structures are formed to sequentially form a cleaning effect on the ground, so that multiple concave structures are formed in the rotational rolling direction to clean the ground in sequence, thereby completing the cleaning effect on the ground;Of course, under the structural setting of the rebound portion 30, the multiple concave structures will also be applied with elastic force by the rebound portion 30 in turn, causing the multiple concave structures to rebound in turn to restore their shapes. It can be seen that the setting of the first contact-changing portion 50 allows the outer surface of the cleaning portion 20 to form a concave structure with a certain depth, which can effectively prevent the problem of poor floor cleaning effect caused by the difficulty in forming the concave structure on the cleaning portion 20 or the concave structure formed on the cleaning portion 20 having a too small depth.

[0086] Preferably, a first touch-change portion 50 is provided on the inner surface of the cleaning portion 20 and the outer surface of the resilient portion 30. The two first touch-change portions 50 at corresponding positions on the two can form a limiting structure in the rotational rolling direction, which can not only effectively guide the formation of the concave structure on the cleaning portion 20, but also effectively enhance the consistency of the resilient portion 30 to drive the cleaning portion 20 to perform synchronous rotational rolling motion.

[0087] The specific structural modes of the first contact-changing portion 50 are as follows:

[0088] The first way is that when the first touch-changing portion 50 is located on the inner surface of the cleaning portion 20, it is set to be a convex structure facing the outer surface of the re-elastic portion 30. At this time, the single first touch-changing portion 50 is a convex structure facing the outer surface of the re-elastic portion 30, and the first touch-changing portion 50 can contact the outer surface of the re-elastic portion 30 at the top position of the convex structure to form a contact structure, which can not only better guide the formation of the concave structure, but also better improve the consistency and stability of the re-elastic portion 30 to drive the cleaning portion 20 to rotate and roll synchronously; the convex structure of the first touch-changing portion 50 will form a concave structure to guide the formation of the cleaning portion 20, and at the same time, if the first touch-changing portion 50 contacts the outer surface of the re-elastic portion 30, a contact friction force will be formed to realize the re-elastic portion 3 0 can stably drive the cleaning part 20 to perform synchronous rotation and rolling motion, thereby improving the cleaning effect of the cleaning part 20 on the ground; when the cleaning part 20 contacts the ground for cleaning, a slightly larger friction force is generated when the outer surface of the cleaning part 20 corresponding to the intersection of the first contact-changing part 50 and the inner surface of the cleaning part 20 contacts the ground. At this time, the outer surface of the cleaning part 20 is deformed and concave in the direction opposite to the rotation and rolling direction to gradually form a concave structure, until the first contact-changing part 50 adjacent to the first contact-changing part 50 contacts the ground at the corresponding position on the cleaning part 20. At this time, a single concave structure is completely formed. In this process, the first contact-changing part 50 guides the formation of the concave structure on the cleaning part 20.

[0089] The second way is that when the first touch-changing portion 50 is located on the outer surface of the resilient portion 30, it is set to be a convex structure facing the inner surface of the cleaning portion 20; at this time, a single first touch-changing portion 50 is a convex structure facing the inner surface of the cleaning portion 20, which can be a structure in which the top position of the first touch-changing portion 50 in the convex direction is in contact with the inner surface of the cleaning portion 20, so that it can not only better guide the formation of the concave structure, but also better improve the consistency and stability of the resilient portion 30 to drive the cleaning portion 20 to rotate and roll synchronously; the convex structure of the first touch-changing portion 50 will form a concave structure to guide the formation of the cleaning portion 20, and at the same time, if the first touch-changing portion 50 contacts the inner surface of the cleaning portion 20, a contact friction force will be formed to realize the resilient portion 3 0 can stably drive the cleaning part 20 to perform synchronous rotation and rolling motion, thereby improving the cleaning effect of the cleaning part 20 on the ground; when the cleaning part 20 contacts the ground for cleaning, a slightly larger friction force is generated when the outer surface of the cleaning part 20 corresponding to the position where the first contact-changing part 50 contacts the inner surface of the cleaning part 20 contacts the ground. At this time, the outer surface of the cleaning part 20 is deformed and concave in the direction opposite to the rotation and rolling direction to gradually form a concave structure, until the first contact-changing part 50 adjacent to the first contact-changing part 50 contacts the ground at the corresponding position on the cleaning part 20. At this time, a single concave structure is completely formed. In this process, the first contact-changing part 50 guides the formation of the concave structure on the cleaning part 20.

[0090] The third way is that when the first contact-changing portion 50 is provided on the inner surface of the cleaning portion 20 and the outer surface of the resilient portion 30, the first contact-changing portions 50 on the two are arranged to be staggered with each other and the first contact-changing portions 50 on the two can be configured to contact each other in the rotational rolling direction, thereby forming a structure that blocks the cleaning portion 20 from independently rotating and rolling relative to the resilient portion 30; at this time, the upper first contact-changing portion 50 of the cleaning portion 20 is in a convex structure toward the outer surface of the resilient portion 30, and the first contact-changing portion 50 on the resilient portion 30 is in a convex structure toward the cleaning portion The inner surface of the cleaning portion 20 is a convex structure. At the same time, the two first contact-changing portions 50 at the corresponding positions on the two are staggered to form a blocking structure that contacts each other, that is, the side portions of the two first contact-changing portions 50 corresponding to the positions of the cleaning portion 20 and the resilient portion 30 contact each other to form a blocking structure in the direction of rotation and rolling, which can not only better guide the formation of the concave structure, but also better improve the consistency and stability of the resilient portion 30 to drive the cleaning portion 20 to rotate synchronously and roll, and better achieve the formation of a blocking structure for the cleaning portion 20 relative to the resilient portion 30. The structure in which the resilient portion 30 performs independent rotational rolling motion can effectively prevent the cleaning portion 20 and the resilient portion 30 from performing independent rotational rolling motion relative to the resilient portion 30 during the rotational rolling motion, effectively ensuring that the cleaning portion 20 and the resilient portion 30 can perform rotational rolling motion synchronously, so that the resilient portion 30 drives the cleaning portion 20 to perform synchronous and consistent rotational rolling motion through the first touch-changing portion 50; wherein, when the cleaning portion 20 contacts the ground for cleaning, a slightly larger friction force is generated when the outer surface position of the cleaning portion 20 corresponding to the intersection of the first touch-changing portion 50 and the inner surface of the cleaning portion 20 contacts the ground. At this time, part of the outer surface of the cleaning portion 20 is deformed and concave in the direction opposite to the rotational rolling direction to gradually form a concave structure, until the first touch-changing portion 50 adjacent to the first touch-changing portion 50 on the cleaning portion 20 contacts the ground at the corresponding position on the cleaning portion 20. At this time, a single concave structure is completely formed, and in this process, the first touch-changing portion 50 guides the formation of the concave structure on the cleaning portion 20.

[0091] For the above three methods, among the specific structural parts, when a first touch-changing part 50 is provided on at least the outer surface of the resilient part 30, the first touch-changing part 50 thereon is set to be a strip-shaped or sheet-shaped structure along the direction of the rotation axis of the cleaning component 2, to form a length structure of the first touch-changing part 50 along the direction of the rotation axis, and then to form a length structure that guides the outer surface of the cleaning part 20 to gradually form a concave structure along the length structure of the first touch-changing part 50 in the direction of the rotation axis, and then to form a concave structure. It can be understood that the depth of the concave structure formed in the radial direction is the cross-sectional shape of the concave structure, and the length structure of the concave structure is formed along the length structure of the first touch-changing part 50, so that the cleaning part 20 is guided to form a concave structure within the length structure range of the rotation axis. length structure, so that the cleaning portion 20 can form a recessed structure with a certain length within the range of the length structure to clean the floor, and the top surface of the first touch-changing portion 50 thereon in the convex direction is constituted to be in contact with the inner surface of the cleaning portion 20, so that it can not only better guide the formation of the recessed structure, but also better improve the consistency and stability of the resilient portion 30 in driving the cleaning portion 20 to rotate and roll synchronously; the convex structure of the first touch-changing portion 50 will form a recessed structure to guide the formation of the cleaning portion 20, and at the same time, if the first touch-changing portion 50 contacts the inner surface of the cleaning portion 20, it will form a contact friction force to realize that the resilient portion 30 can stably drive the cleaning portion 20 to rotate and roll synchronously, thereby improving the cleaning effect of the cleaning portion 20 on the floor.

[0092] And / or, in the specific structural part, when a first contact-changing portion 50 is provided at least on the inner surface of the cleaning portion 20, the first contact-changing portion 50 thereon is provided to be a strip-shaped or sheet-shaped structure along the direction of the rotation axis of the cleaning component 2, to form a length structure of the first contact-changing portion 50 along the direction of the rotation axis, and then to form a length structure that guides the outer surface of the cleaning portion 20 to gradually form a concave structure along the length structure of the first contact-changing portion 50 in the direction of the rotation axis, and then to form a concave structure. It can be understood that the depth of the concave structure formed in the radial direction is the cross-sectional shape of the concave structure, and the length structure of the concave structure formed along the length structure of the first contact-changing portion 50 realizes that the cleaning portion 20 is guided to form a concave structure within the length structure range of the rotation axis. The structure has a certain length, so that the cleaning part 20 can form a recessed structure with a certain length within the range of the length structure to clean the ground, and the top surface of the first touch-changing part 50 thereon in the convex direction is constituted to be in contact with the outer surface of the resilient part 30, which can not only better guide the formation of the recessed structure, but also better improve the consistency and stability of the resilient part 30 in driving the cleaning part 20 to rotate and roll synchronously; the convex structure of the first touch-changing part 50 will form a recessed structure to guide the formation of the cleaning part 20, and at the same time, if the first touch-changing part 50 contacts the outer surface of the resilient part 30, it will form a contact friction force to realize that the resilient part 30 can stably drive the cleaning part 20 to rotate and roll synchronously, thereby improving the cleaning effect of the cleaning part 20 on the ground.

[0093] In this solution, in order to better form the formation of the guiding recessed structure, it is prevented that the recessed structure on the cleaning portion 20 is difficult to form or that the recessed depth formed by the cleaning portion 20 is too small, resulting in poor cleaning effect on the floor; this solution can also be that a plurality of second contact-changing portions 60 with a recessed structure or a convex structure are provided on the outer surface of the cleaning portion 20, and the plurality of second contact-changing portions 60 are distributed in a spaced-apart structure in the direction of rotation and rolling, so that when the cleaning portion 20 contacts the floor, the arc surface structure on its outer surface is guided and deformed in a circular direction by the position of the second contact-changing portion 60 in the direction of rotation and rolling, thereby forming a recessed structure for cleaning the floor; specifically, the second contact-changing portions 60 are provided on the outer surface of the cleaning portion 20. The changing portion 60 is convex toward the outside or concave toward the inside on the outer surface of the cleaning portion 20. A single second contact-changing portion 60 also extends out along the direction of the rotation axis to form its length structure. Multiple second contact-changing portions 60 form a spaced distribution structure in the rotation and rolling direction. When the cleaning portion 20 contacts the ground for cleaning, when a certain second contact-changing portion 60 in the rotation and rolling direction contacts the ground, it will form a greater friction or resistance. Under the structure with increased friction or resistance, the arc surface structure part on the outer surface of the cleaning portion 20 will be guided and deformed in the annular direction to form a concave structure for cleaning the ground. The formation of the concave structure is first started by the second contact-changing portion 60 at the corresponding position on the cleaning portion 20. The cleaning part 20 is gradually recessed, and then gradually recessed in the annular direction in the direction opposite to the rotation and rolling direction to form a recessed structure until the next second contact-changing part 60 is at the corresponding position on the cleaning part 20, so as to realize the formation of a single recessed structure and form a cleaning effect on the ground during the formation process; that is, the single recessed structure is formed between two adjacent second contact-changing parts 60 in the rotation and rolling direction or the annular direction, that is, a single recessed structure is formed between two adjacent second contact-changing parts 60. In the process of continuous rotation and rolling of the cleaning part 20, recessed structures are formed in sequence between two adjacent second contact-changing parts 60 at different positions in the rotation and rolling direction, thereby forming a recessed structure in sequence. The concave structures are used to form a cleaning effect on the ground in sequence, so that multiple concave structures are formed in the rotational rolling direction to clean the ground in sequence, thereby completing the cleaning effect on the ground; of course, under the structural setting of the rebound part 30, multiple concave structures will also be applied with elastic driving force by the rebound part 30 in sequence to make multiple concave structures rebound in sequence to restore their shapes. It can be seen that the setting of the second touch-change part 60 enables a concave structure to be formed on the outer surface of the cleaning part 20 and to form a certain concave depth, which can effectively prevent the problem of poor cleaning effect on the ground caused by the difficulty in forming the concave structure on the cleaning part 20 or the small depth of the concave structure formed on the cleaning part 20.

[0094] Among them, it can be understood that the depth of the recessed structure formed in the radial direction is the cross-sectional shape of the recessed structure, and the length structure of the recessed structure is formed along the length structure of the second touch-changing portion 60, so that the cleaning portion 20 can be guided to form the length structure of the recessed structure within the length structure range of the rotation axis, and the cleaning portion 20 can form a recessed structure with a certain length within the range of the length structure to clean the ground, which can better guide the formation of the recessed structure. The convex structure or recessed structure of the second touch-changing portion 60 will form a recessed structure on the guiding cleaning portion 20.

[0095] It can be understood that in the present embodiment, when the first touch-change portion 50 or the second touch-change portion 60 is not provided, the overall structure of the cleaning portion 20 in the direction of rotation and rolling is uniform. At this time, it is not easy to deform toward the first space area 40 when contacting the ground, which will make the effect of the cleaning portion 20 to deform to form a concave structure worse. Even if it deforms to form a concave structure when contacting the ground under pressure, the depth of the concave structure will be shallow, and it will not be able to better accommodate dirty liquid and garbage, resulting in poor cleaning effect of the cleaning portion 20 on the ground.

[0096] In this solution, in order to further enhance the elastic effect of the rebound portion 30 and further enhance the stability and reliability of the elastic driving force of the rebound portion 30 on the cleaning portion 20, a hole structure 70 or a pit structure 80 is provided on the rebound portion 30. When the outer surface of the cleaning portion 20 is deformed and recessed, at least a portion of its outer surface contacts and presses the hole structure 70 or the pit structure 80 to form a synchronously deformed and recessed structure. When the outer surface of the cleaning portion 20 is separated from the ground and rebounds to restore its shape, the hole structure 70 or the pit structure 80 forms an elastic driving force on the cleaning portion 20. The concave structure on the cleaning part 20 is restored to the cambered structure; the hole structure 70 is arranged on the resilient part 30 to form a structure in which a plurality of holes 701 are distributed along the radial direction and a structure in which a plurality of holes 701 are distributed along the annular direction or the rotational rolling direction. At this time, the holes 701 are open on one side of the end face of the resilient part 30 on both sides of the rotation axis. At the same time, the hole structure 70 is also arranged to form a structure in which a plurality of holes 701 are distributed along the direction of the rotation axis. At this time, the holes 701 are open on the outer side of the outer surface of the resilient part 30 in the radial direction. The pit structure 80 is configured to form a structure in which a plurality of pits 801 are distributed along the radial direction on the resilient portion 30, and a structure in which a plurality of pits 801 are distributed along the annular direction or the rotational rolling direction. At this time, the pits 801 are open on one side of the end face of the resilient portion 30 on both sides of the rotation axis. At the same time, the pit structure 80 is also configured to form a structure in which a plurality of pits 801 are distributed along the direction of the rotation axis. At this time, the pits 801 are open on the outer side of the outer surface of the resilient portion 30 in the radial direction. The setting of the hole structure 70 or the pit structure 80 makes The resilient part 30 has a relatively large elastic amount in the radial direction, can be more easily compressed, and can be more easily restored by the deformation and rebound of the compressed structure. At the same time, it will greatly improve the durability and reliability of the deformation and elastic amount generated by the resilient part 30, and form a certain buffering effect. In this way, a guiding recessed structure can be gradually formed in the radial direction, that is, the depth of the recess gradually deepens under the buffering effect of the resilient part 30, and there will be no problem of sudden increase in the depth of the recess or sudden shallowing of the depth of the recess, thereby effectively improving the cleaning effect on the ground.Among them, when the outer surface of the cleaning part 20 contacts the ground, a part of the arc surface structure on the outer surface of the cleaning part 20 is deformed to contact the hole structure 70 or the pit structure 80 to form a crimping structure, and the hole structure 70 or the pit structure 80 is gradually compressed to form the resilient part 30 to slowly generate a gradually increasing amount of elasticity. At the same time, when the recessed structure rebounds, the hole structure 70 or the pit structure 80 forms a slow and gradual elastic driving force, thereby slowly pushing the recessed structure of the cleaning part 20 to deform and rebound to restore to the arc surface shape. In this way, the deformation process of the outer surface of the cleaning part 20 and the deformation process of the resilient part 30 can be effectively improved to a slow process, rather than a sudden and rapid deformation process, thereby preventing the resilient part 30 and the cleaning machine from aging, breakage under long-term deformation and other problems caused by sudden deformation, and improving the reliability and stability of the cleaning part 20 and the resilient part 30 for long-term deformation.

[0097] Among them, the hole structure 70 or the pit structure 80 on the re-elastic part 30 mainly includes two parts of holes 701 or pits 801. The first part is the holes 701 or pits 801 on the re-elastic part 30 that are open in the outer direction of the outer surface of the re-elastic part 30, mainly multiple holes 701 or multiple pits 801 that are open in the outer direction of the outer surface of the re-elastic part 30 in the rotational rolling direction; the second part is the multiple holes 701 or multiple pits 801 on the re-elastic part 30 that are open in the outer direction of the outer surface of the re-elastic part 30 in the rotational rolling direction; the first part and the second part together constitute the hole structure 70 or pit structure 80 on the re-elastic part 30.

[0098] The specific structural part is arranged that when the cleaning part 20 is deformed to form a recessed structure, at least a part of the recessed structure is used to form a contact hole structure 70 or a pit structure 80 and form a pressure contact force, so that the hole structure 70 is deformed and compressed along the axial direction of the hole 701 thereon or the pit structure 80 is deformed and compressed along the axial direction of the pit 801 thereon. In the process of forming the recessed structure of the cleaning part 20, a continuous pressure contact force is formed on the elastic part 30. Under the action of the pressure contact force, the hole structure 70 or the pit structure 80 is compressed, and then the hole structure 70 or the pit structure 80 forms a certain distance of elasticity to deform, and under the deformed structure, the recessed depth of the recessed structure gradually increases. The hole structure 70 is large, and finally forms a concave structure with a certain depth to clean the ground, so as to accommodate the dirty liquid and garbage on the ground and drive the transfer and collection. The hole structure 70 is mainly deformed and compressed along the axial direction of the hole 701 during the compression process. The concave structure is mainly deformed and compressed along the axial direction of the pit 801 during the compression process, and finally realizes the formation of the concave structure by cooperating with the pit structure 80 or the hole structure 70 to the cleaning part 20, and when the concave structure rebounds to restore its shape, the hole structure 70 or the pit structure 80 deforms and rebounds to generate an elastic driving force, and the concave structure on the cleaning part 20 is rebounded and restored to its shape with the help of the elastic driving force.

[0099] In order to further enhance the elastic pushing effect of the hole structure 70 or the pit structure 80 on the recessed structure on the cleaning portion 20, and enhance the effective rebound recovery of the recessed structure, in this solution, at least a portion of the hole structures 70 or at least a portion of the pit structures 80 are configured to be recessed along the radial direction of the cleaning portion 20 toward the inner side of the resilient portion 30, so that the resilient portion 30 is an elastic structure in the radial direction and can form an elastic pushing force on the cleaning portion 20 when deformed. By being configured to be recessed in the radial direction toward the inner side of the resilient portion 30, a better recessed direction that matches the recessed structure can be formed. The recessed structure on the cleaning portion 20 is recessed in the recessed direction to form a hole structure 70 or a pit structure 80. This can enhance the deformation and compression effect of the hole structure 70 or the pit structure 80 when the recessed structure on the cleaning portion 20 is pressed, and can enhance the hole structure 70 or the pit structure 80 to better form an elastic driving force on the recessed structure on the cleaning portion 20 in the radial direction; specifically, the hole 701 or the pit 801 that is an open structure on the re-elastic portion 30 facing the outer side of the outer surface of the re-elastic portion 30 in the rotational rolling direction is mainly set as a structure that is recessed in the radial direction toward the inner side of the re-elastic portion 30.

[0100] Or, in order to further enhance the elastic pushing effect of the hole structure 70 or the pit structure 80 on the recessed structure on the cleaning portion 20, and enhance the effectiveness of the recessed structure in rebounding and restoring the shape, in this solution, at least a portion of the hole structure 70 or at least a portion of the pit structure 80 is configured to be recessed along the radial direction of the cleaning portion 20 toward the inner side of the resilient portion 30, so that the resilient portion 30 is an elastic structure in the radial direction and can form an elastic pushing force on the cleaning portion 20 when deformed. By being configured to be recessed in the radial direction toward the inner side of the resilient portion 30, a better recessed direction that matches the recessed structure can be formed, thereby forming a recessed structure along the cleaning portion 20. The hole structure 70 or the pit structure 80 is formed by being recessed in the recessed direction of the structure, so as to enhance the deformation and compression effect of the hole structure 70 or the pit structure 80 when the recessed structure on the cleaning part 20 is pressed, and the hole structure 70 or the pit structure 80 can be enhanced to better form an elastic driving force on the recessed structure on the cleaning part 20 in the radial direction; specifically, the hole 701 or the pit 801 on the re-elastic part 30 which is an open structure in the outer direction of the outer surface of the re-elastic part 30 in the rotational rolling direction is mainly a part in the radial direction or a part in the axial direction, which is set to be recessed in the radial direction toward the inner side of the re-elastic part 30.

[0101] In order to further enhance the elastic pushing effect of the hole structure 70 or the pit structure 80 on the recessed structure on the cleaning portion 20, and enhance the effective rebound recovery of the recessed structure, in the present solution, at least a portion of the hole structures 70 or at least a portion of the pit structures 80 are configured to be arc-shaped or linearly inclined in the direction of rotation and rolling, so that the resilient portion 30 forms an elastic pushing force on the cleaning portion 20 in the inclined direction; mainly, the holes 701 or pits 801 on the resilient portion 30 that are open in the outer direction of the outer surface of the resilient portion 30 in the direction of rotation and rolling are configured to be arc-shaped or linearly inclined in the direction of rotation and rolling, so as to realize the shape along the arc-shaped inclined direction or the linearly inclined direction. The elastic driving force of the recessed structure of the paired cleaning portion 20, because the cleaning portion 20 is always in a rotating and rolling motion state during the process of cleaning the floor, the setting of an arc-shaped inclined structure or a straight-line inclined structure can better generate an elastic driving force on the recessed structure along the rotating and rolling direction, to form an elastic pushing effect of the recessed structure along the rotating and rolling direction to rebound and restore the shape, thereby helping to enhance the elastic pushing effect of the hole structure 70 or the pit structure 80 on the recessed structure on the cleaning portion 20, and also helping to form a cavity structure to rebound and restore the shape along the rotating and rolling direction, and in the process of rebounding, the dirty liquid and garbage can be pushed toward the rotating and rolling direction, so that better collection of dirty liquid and garbage can be achieved.

[0102] Preferably, at least a portion of the hole structures 70 or at least a portion of the pit structures 80 are arranged to be arc-shaped or linearly inclined structures with a height relative to the ground gradually decreasing in the direction of rotation and rolling.

[0103] Or, in order to further enhance the elastic pushing effect of the hole structure 70 or the pit structure 80 on the recessed structure on the cleaning portion 20, and enhance the effective rebound recovery of the recessed structure, in this solution, at least a portion of the hole structure 70 or at least a portion of the pit structure 80 is configured to be an arc-shaped inclined or linearly inclined structure in the direction of rotation and rolling, so that the resilient portion 30 forms an elastic pushing force on the cleaning portion 20 in the inclined direction, mainly for the hole 701 or the pit 801 on the resilient portion 30 that is open in the radial direction or in the axial direction, which is an arc-shaped inclined or linearly inclined structure in the direction of rotation and rolling, to achieve an arc-shaped inclined direction. An elastic driving force is formed on the concave structure of the cleaning part 20 in the direction of rotation or straight line inclination. Since the cleaning part 20 is always in a rotating and rolling motion state during the process of cleaning the ground, an arc-shaped inclined structure or a straight line inclined structure is set to better generate an elastic driving force on the concave structure along the rotating and rolling direction, so as to form an elastic pushing effect of the concave structure along the rotating and rolling direction to rebound and restore the shape, thereby helping to enhance the elastic pushing effect of the hole structure 70 or the pit structure 80 on the concave structure on the cleaning part 20, and also helping to form a concave cavity structure to rebound and restore the shape along the rotating and rolling direction. During the rebound process, the dirty liquid and garbage can be pushed toward the rotating and rolling direction, so that better collection of dirty liquid and garbage can be achieved.

[0104] Preferably, at least a portion of the hole structure 70 or at least a portion of the pit structure 80 is configured to be an arc-shaped or linearly inclined structure with a height relative to the ground gradually decreasing in the direction of rotation and rolling.

[0105] In the specific structural part, the hole structure 70 or the pit structure 80 is set to be an interval distribution structure along the rotation and rolling direction of the re-elastic part 30 and is set to be an interval distribution structure along the rotation axis direction of the re-elastic part 30. When the cleaning part 20 forms a recessed structure along the rotation axis, the hole structure 70 or the pit structure 80 can form an elastic driving force in the length range of the recessed structure along the rotation axis direction; that is, the hole structure 70 or the pit structure 80 is not only constituted to form a filling and covering structure in the radial direction, a plurality of holes 701 or pits 801 are formed in the filling and covering area and are spaced apart along the radial direction. At this time, the hole structure 70 or the pit structure 80 is mainly toward one of the end faces on both sides of the rotation axis of the re-elastic part 30. It is also constituted to form a filling and covering structure in the rotation and rolling direction, a plurality of holes 701 or pits 801 are formed in the filling and covering area and are spaced apart along the rotation and rolling direction. At this time, the hole structure 70 or the pit structure 80 is mainly toward The outer side of the outer surface of the resilient part 30 is an open structure, and at the same time, it is also constituted as a filling and covering structure along the direction of the rotation axis, that is, along the length direction of the cleaning part 20. In the area of ​​the covering structure, multiple holes 701 or pits 801 are distributed in an interval structure along the direction of the rotation axis, thereby realizing the length structure of the resilient part 30, and forming a hole structure 70 or a pit structure 80 for filling and covering within the length range of the resilient part 30. When the cleaning part 20 contacts the ground for cleaning, a continuous recessed structure can be formed along the length direction, thereby forming a length range of the recessed structure. At the same time, the hole structure 70 or the pit structure 80 can form an elastic driving force in the length range of the recessed structure along the direction of the rotation axis or the length direction of the cleaning part 20, so that the cleaning part 20 can contact the ground within the length range to form a recessed structure for cleaning the ground, and the resilient part 30 correspondingly forms an elastic driving force on the recessed structure along the length direction so that the recessed structure rebounds and restores its shape.

[0106] And / or, in order to further enhance the elastic pushing effect of the hole structure 70 or the pit structure 80 on the recessed structure on the cleaning portion 20, and enhance the effective rebound recovery of the recessed structure, in the present solution, a plurality of hole structures 70 or a plurality of pit structures 80 can be provided in two adjacent hole structures 70 or two adjacent pit structures 80 along the direction of the rotation axis to form a structure that is interconnected, so that when the resilient portion 30 is deformed, the airflow generated in the hole structure 70 or the pit structure 80 during the deformation process can flow in the direction of the rotation axis, that is, the hole 701 or pit 8 on the resilient portion 30 is an open structure facing one of the end faces on both sides of the resilient portion 30 on the rotation axis. 01 can be constructed as a structure that is connected on the rotation axis, so that the air flow can be realized in the direction of the rotation axis. At the same time, the air flow can enter the re-elastic part 30 from the hole 701 or the pit 801 with an open structure on the outside of the outer surface of the re-elastic part 30 toward the re-elastic part 30, and form an air flow effect in the hole 701 or the pit 801 with an open structure on one of the end faces on both sides of the rotation axis, thereby preventing the cleaning part 20 from forming a vacuum when contacting and pressing the hole structure 70 or the pit structure 80 on the re-elastic part 30. It can be understood that when the outer surface of the cleaning part 20 contacts the ground for cleaning, the concave structure is gradually formed and contacts the re-elastic part 30. The outer surface of the resilient part 30 is provided with a plurality of holes 701 or a plurality of pits 801 in an open structure to form a compressed state of the resilient part 30. In the compressed state, if the airflow in the holes 701 or the pits 801 cannot flow in time, the airflow will form resistance in the holes 701 or the pits 801 to prevent the resilient part 30 from being compressed, which will cause the concave structure to be unable to be concave to a certain depth due to the effect of resistance during the concave process, affecting the cleaning effect of the ground. By forming a structure that is interconnected between two adjacent hole structures 70 or two adjacent pit structures 80 along the direction of the rotation axis, the airflow can flow during the compression of the resilient part 30, thereby improving the concave structure. The formation of the structure enables the resilient part 30 to be effectively compressed. At the same time, when the hole structure 70 or the pit structure 80 on the resilient part 30 forms an elastic driving force on the recessed structure, the air flow will flow from the resilient part 30 toward the hole 701 or the pit 801 with an open structure on one of the end faces on both sides of the rotation axis of the resilient part 30, and toward the hole 701 or the pit 801 with an open structure on the resilient part 30 toward the outside of the outer surface of the resilient part 30, forming an air flow supply effect, thereby ensuring that the resilient part 30 can effectively recover to its natural state from the deformation and expansion of the compression structure, and in this process, an elastic driving force is formed on the recessed structure, so that the recessed structure on the cleaning part 20 can effectively rebound and recover its shape.

[0107] In order to further enhance the elastic pushing effect of the hole structure 70 or the pit structure 80 on the recessed structure on the cleaning portion 20, and enhance the effective rebound recovery of the recessed structure, in the present embodiment, at least a portion of the hole structures 70 or at least a portion of the pit structures 80 can be configured as a structure with an inner diameter gradually decreasing from one end close to the inner surface of the cleaning portion 20 toward the end close to the rotation axis of the cleaning portion 20; the hole 701 or the pit 801 mainly on the resilient portion 30 with an open structure toward the outside of the outer surface of the resilient portion 30 is configured as a structure with an inner diameter gradually decreasing from one end close to the inner surface of the cleaning portion 20 toward the end close to the rotation axis of the cleaning portion 20; The end toward the end of the rotation axis close to the cleaning part 20 has a structure with a gradually decreasing inner diameter value, that is, the hole 701 or pit 801 in this part has a trumpet-shaped structure with a gradually increasing inner diameter value from the inside to the outside of the resilient part 30. In this way, when the recessed structure on the cleaning part 20 is crimped against the resilient part 30, the hole structure 70 or the pit structure 80 can be more easily compressed to form a certain amount of elasticity. At the same time, when the hole structure 70 or the pit structure 80 elastically pushes the recessed structure on the cleaning part 20, it can better form an elastic driving force, thereby promoting the recessed structure to effectively rebound and restore its shape.

[0108] Or, in order to further enhance the elastic pushing effect of the hole structure 70 or the pit structure 80 on the recessed structure on the cleaning portion 20, and enhance the effective rebound recovery of the recessed structure, in this solution, at least a portion of the hole structures 70 or at least a portion of the pit structures 80 can be set to have an inner diameter value formed at one end position close to the inner surface of the cleaning portion 20 that is greater than the inner diameter value formed at one end close to the rotation axis of the cleaning portion 20, mainly for the hole 701 or pit 801 on the resilient portion 30 that is open toward the outside of the outer surface of the resilient portion 30, and is set to be close to the inner surface of the cleaning portion 20. The inner diameter value formed at one end position is greater than the inner diameter value formed at one end close to the rotation axis of the cleaning part 20, that is, the hole 701 or pit 801 in this part has an inner diameter value increasing from the inside to the outside of the resilient part 30. In this way, when the recessed structure on the cleaning part 20 is crimped to the resilient part 30, the hole structure 70 or the pit structure 80 can be more easily compressed to form a certain amount of elasticity. At the same time, when the hole structure 70 or the pit structure 80 elastically pushes the recessed structure on the cleaning part 20, an elastic driving force can be better formed, thereby promoting the recessed structure to effectively rebound and restore its shape.

[0109] The specific structural part of the resilient part 30 is that an outer elastic layer and an inner elastic layer are provided on the resilient part 30, and a hole structure 70 or a pit structure 80 is provided on both the outer elastic layer and the inner elastic layer; the outer elastic layer is mainly located at the outer ring position of the inner elastic layer to form a ring-shaped structure, and the inner elastic layer is located at the inner ring of the outer elastic layer to form a ring-shaped structure, mainly to form in the radial direction the inner elastic layer is located on the inner side and the outer elastic layer is located on the outer side, and a plurality of holes 701 or pits 801 are distributed in the radial direction, the rotational rolling direction and the rotation axis direction of the resilient part 30, so that the resilient part 30 can better cooperate with the formation of the concave structure in the radial direction, the rotational rolling direction and the rotation axis direction and cooperate to help the concave structure to rebound and restore its shape.

[0110] In order to further enhance the elastic pushing effect of the hole structure 70 on the concave structure on the cleaning portion 20, and enhance the concave structure to effectively rebound and restore the shape, in this solution, when the hole structure 70 is set, the hole 701 distribution density on the hole structure 70 on the outer elastic layer is set to be greater than or equal to the hole 701 distribution density on the hole structure 70 on the inner elastic layer. The density of the holes 701 distributed in the radial direction of the outer elastic layer is greater than the density of the holes 701 distributed in the inner elastic layer, which can better form the effect of air flow, or the density of the holes 701 distributed in the outer elastic layer in the direction of rotation and rolling or in the direction of the rotation axis is greater than that of the holes 701 distributed in the inner elastic layer in the direction of rotation and rolling or in the direction of the rotation axis. The density of the holes 701 distributed in the direction of the rotation axis can better form a single concave structure that contacts more holes 701, thereby forming multiple holes 701 that can provide a more uniform and stable elastic driving force, and / or when the hole structure 70 is provided, the holes 701 on the hole structure 70 on the outer elastic layer and the holes 701 on the hole structure 70 on the inner elastic layer are arranged in a staggered distribution structure in the radial direction. The staggered distribution structure can achieve that the hole structure 70, when compressed, can be more balanced and stable in the radial direction, resulting in a better consistency effect during compression, and can also achieve that the holes 701 provide a more uniform and stable elastic driving force.

[0111] Or, in order to further enhance the elastic pushing effect of the concave structure 80 on the concave structure on the cleaning portion 20, and enhance the effective rebound recovery of the concave structure, in this solution, when the concave structure 80 is provided, the distribution density of the concave 801 on the concave structure 80 on the outer elastic layer is greater than or equal to the distribution density of the concave 801 on the inner elastic layer. The distribution density of the concave 801 on the outer elastic layer in the radial direction is greater than the distribution density of the concave 801 on the inner elastic layer, so as to better form the effect of air flow, or the distribution density of the concave 801 on the outer elastic layer in the rotational rolling direction or the direction of the rotation axis is greater than the distribution density of the concave 801 on the inner elastic layer in the rotational rolling direction or the direction of the rotation axis. The density of the distribution of the pits 801 in the direction of the rotation axis can better form a single concave structure that contacts more pits 801, thereby forming multiple pits 801 that can provide a more uniform and stable elastic driving force, and / or when the pit structure 80 is provided, the pits 801 on the pit structure 80 on the outer elastic layer and the pits 801 on the pit structure 80 on the inner elastic layer are staggered in the radial direction. The staggered distribution structure can achieve that the pit structure 80, when compressed, can be compressed more uniformly and stably in the radial direction, resulting in a better consistency effect during compression, and can also achieve that the pits 801 provide a more uniform and stable elastic driving force.

[0112] In this solution, the inner diameter of the hole 701 on the hole structure 70 or the inner diameter of the pit 801 on the pit structure 80 is set to be smaller than the depth of the recessed structure on the cleaning part 20. This is mainly because the inner diameter of the hole 701 or the pit 801 on the resilient part 30, which is an open structure facing the outer side of the outer surface of the resilient part 30 in the rotational rolling direction, is smaller than the depth of the recessed structure on the cleaning part 20. In this way, the resilient part 30 can be more easily compressed by the recessed structure of the cleaning part 20, and the resilient part 30 can provide a more stable elastic driving force to the recessed structure of the cleaning part 20.

[0113] Preferably, the inner diameter of the hole 701 or pit 801 in the outer side of the outer surface of the resilient part 30 in the rotational rolling direction is set to be smaller than half of the depth of the recessed structure on the cleaning part 20. In this way, the resilient part 30 can be more easily compressed by the recessed structure of the cleaning part 20, and the resilient part 30 can provide a more stable elastic driving force to the recessed structure of the cleaning part 20.

[0114] Or, in this solution, the inner diameter value of the hole 701 on the hole structure 70 or the inner diameter value of the pit 801 on the pit structure 80 is set to be less than or equal to the thickness value formed in the radial direction of the cleaning part 20 or twice the thickness value; mainly, the inner diameter value of the hole 701 or the pit 801 on the re-elastic part 30 facing the outer side of the outer surface of the re-elastic part 30 in the rotational rolling direction is less than or equal to the thickness value formed in the radial direction of the cleaning part 20 or twice the thickness value, so that the re-elastic part 30 can be more easily compressed by the recessed structure of the cleaning part 20, and the re-elastic part 30 can provide a more stable elastic driving force to the recessed structure of the cleaning part 20.

[0115] Or, in this solution, the inner diameter value of the hole 701 on the hole structure 70 or the inner diameter value of the pit 801 on the pit structure 80 is set to be less than or equal to the thickness value formed in the radial direction of the cleaning part 20 or twice the thickness value, and the thickness value formed in the radial direction of the cleaning part 20 is set to be less than or equal to 1.5 mm; the inner diameter value of the hole 701 or the pit 801 on the resilient part 30 facing the outer side of the outer surface of the resilient part 30 in the rotational rolling direction is mainly less than or equal to the thickness value formed in the radial direction of the cleaning part 20 or twice the thickness value, so that the resilient part 30 can be more easily compressed by the concave structure of the cleaning part 20, and the resilient part 30 can also provide a more stable elastic driving force to the concave structure of the cleaning part 20; at the same time, the thickness value formed in the radial direction of the cleaning part 20 is less than or equal to 1.5 mm, so that the cleaning part 20 can be better deformed, so that the softness and deformability of the cleaning part 20 are better, and it is easier to form a concave structure.

[0116] Preferably, the cleaning portion 20 is provided with a thickness in the radial direction greater than or equal to 0.75 mm and less than or equal to 1.15 mm.

[0117] The cleaning element 2 is fixed to the inner surface of the cleaning element 2 and the inner surface of the cleaning element 2 is fixed to the inner surface of the cleaning element 2. The cleaning element 2 is fixed to the inner surface of the cleaning element 2 and the inner surface of the cleaning element 2 is fixed to the inner surface of the cleaning element 2.

[0118] In order to improve the effective formation of the concave structure on the cleaning part 20 and the effective rebound and recovery of the concave structure, in this solution, the thickness value formed between the outer surface and the inner surface of the resilient part 30 in the radial direction can be set to be greater than the maximum concave depth value of the concave structure on the cleaning part 20, so that when the cleaning part 20 contacts the ground and deforms to form the concave structure, a part of the cleaning part 20 is pressed toward the resilient part 30 to compress the resilient part 30. The resilient part 30 will effectively deform during the compression process. At the same time, the maximum concave depth of the concave structure will not exceed the thickness value of the resilient part 30, so that the concave structure can be better formed. At the same time, the maximum concave depth of the concave structure is less than the thickness value formed between the outer surface and the inner surface of the resilient part 30 in the radial direction, so that the corresponding uncompressed position area of ​​the resilient part 30 in the radial direction can effectively accumulate elastic driving force, and then effectively form an elastic driving force on the concave structure in the radial direction, thereby effectively improving the rebound and recovery of the concave structure to the arc surface structure effect.

[0119] Alternatively, in order to improve the effective formation of the concave structure on the cleaning part 20 and the effective rebound recovery of the concave structure, in this solution, the thickness value between the outer surface and the inner surface of the resilient part 30 in the radial direction can be set to be greater than half of the radius value formed by the cleaning part 20 in the undeformed structure. In this way, the thickness value of the resilient part 30 in the radial direction has a sufficiently large filling coverage range, so that the resilient part 30 can effectively form a filling coverage area in the radial direction. Under this filling coverage area, the cleaning part 20 can effectively crimp the resilient part 30 so that the resilient part 30 is compressed, thereby realizing the effective formation of the concave structure on the cleaning part 20. At the same time, the corresponding uncompressed position area of ​​the resilient part 30 in the radial direction can effectively accumulate elastic driving force, thereby effectively forming an elastic driving force on the concave structure in the radial direction, thereby effectively improving the rebound recovery of the concave structure to the arc surface structure effect.

[0120] Optionally, the thickness between the outer surface and the inner surface of the resilient portion 30 in the radial direction is set to be greater than half of the radius of the circle where the outer surface formed by the cleaning portion 20 in the undeformed structure is located.

[0121] The cam 31 is provided with a plurality of retaining members 32 and 33, and the retaining members 33 are provided with retaining members 34. The retaining members 34 are provided with retaining members 35. The retaining members 34 are provided with retaining members 36.

[0122] In this solution, in order to further enhance the deformation and elastic pushing effect of the resilient portion 30, and to further enhance the rebound and shape recovery effect of the recessed structure on the cleaning portion 20, the hardness value of the resilient portion 30 in the radial direction can be set to be no greater than the hardness value in the rotational rolling direction, so that when the resilient portion 30 is deformed in the radial direction, it constitutes a continuous filling and covering structure in the rotational rolling direction; the resilient portion 30 can have a softer structure in the radial direction, and can be effectively deformed in the radial direction, which is beneficial to the formation of the recessed structure on the cleaning portion 20, and is also beneficial to the rebound and shape recovery of the recessed structure on the cleaning portion 20; it can be understood that when the cleaning portion 20 is deformed in the radial direction to form the recessed structure, a crimping effect is formed on the resilient portion 30, which compresses the resilient portion 30, and the resilient portion 30 can be realized under the structure with a softer radial direction. The resilient portion 30 is now more easily compressed to cooperate with the cleaning portion 20 to deform and concave, thereby improving the effect of forming the concave structure; and, when the resilient portion 30 forms an elastic driving force, the resilient portion 30 has a softer structure in the radial direction, which can realize the rebound of the resilient portion 30 to generate an elastic driving force, thereby realizing the effect of the concave structure rebounding and recovering to the arc shape; the hardness value of the resilient portion 30 in the rotational rolling direction is greater than or equal to the hardness value of the resilient portion 30 in the radial direction, so that the resilient portion 30 has a harder structure in the rotational rolling direction relative to the radial direction, so that the resilient portion 30 can better form a continuous filling and covering structure in the rotational rolling direction, so that the resilient portion 30 is not easily broken or damaged in the rotational rolling direction due to the rotational force, thereby improving the stability and reliability of the resilient portion 30 in the rotational rolling direction to drive the cleaning portion 20 to perform synchronous rotational rolling motion.

[0123] Optionally, the re-elastic portion 30 is configured as a complete annular structure in the rotational rolling direction, and then forms a complete continuous filling and covering structure in the annular direction, so that the structure of the re-elastic portion 30 in the rotational rolling direction is more stable and not easy to crack or break. This can effectively improve the stability and reliability of the re-elastic portion 30 in the annular direction to drive the cleaning portion 20 to perform synchronous rotational rolling motion.

[0124] Preferably, when the hardness value of the resilient portion 30 in the rotational rolling direction is greater than the hardness value thereof in the radial direction, the structure of the resilient portion 30 is more stable and the effect is better.

[0125] The soft structural part of the above-mentioned resilient part 30, the hardness value of the resilient part 30 in the radial direction is not greater than the hardness value in the rotational rolling direction. It can be understood that it is not limited to being composed of only different materials, and can also be achieved through the distribution density of the hole structure 70 or the distribution density of the pit structure 80, or the hole 701 on the hole structure 70 or the pit 801 on the pit structure 80, which can satisfy the structure that the resilient part 30 can have a larger hardness value in the rotational rolling direction, and satisfy the structure that the resilient part 30 can have a smaller hardness value in the rotational rolling direction, that is, a better soft structure.

[0126] In this solution, in order to further enhance the deformation and elastic propulsion effect of the resilient part 30, and enhance the better effect of the cleaning part 20 in rubbing the ground for cleaning, the hardness value of the cleaning part 20 can be set to be greater than the hardness value of the resilient part 30 to form a softer structure of the resilient part 30 relative to the cleaning part 20: by setting the resilient part 30 to have a softer structure, the resilient part 30 can be better compressed by the cleaning part 20 and then deformed into a concave shape, and can better form an elastic propulsion force on the cleaning part 20 so that the concave structure of the cleaning part 20 can rebound more quickly and stably to restore to the arc surface structure shape, thereby achieving that the cleaning part 20 can better clean the ground.

[0127] Optionally, the hardness value of the resilient portion 30 in the radial direction and the hardness value in the rotational rolling direction are both smaller than the hardness value of the cleaning portion 20, so that the resilient portion 30 can better cooperate with the cleaning portion 20 to deform, thereby improving the formation of the concave structure and the rebound effect of the concave structure.

[0128] Alternatively, in this solution, in order to further improve the reliability and stability of the cleaning part 20 in rubbing the ground for cleaning, and to further improve the deformation effect of the resilient part 30, the wear rate of the cleaning part 20 can be set to be lower than the wear rate of the resilient part 30; the wear resistance of the cleaning part 20 is better than that of the resilient part 30, so that the cleaning part 20 is not easily damaged during the process of contacting the ground for rotating and rolling motion to clean the ground. Better wear resistance can make the cleaning part 20 have better reliability and stability, and longer service life. At the same time, the resilient part 30 has relatively poor wear resistance, so that the resilient part 30 can be better deformed. Under this structure, the resilient part 30 can be set to have just the right softness and flexibility, so as to achieve the improvement of the resilient part 30 to more stably and reliably drive the cleaning part 20 to perform synchronous rotation and rolling motion.

[0129] Alternatively, in this solution, in order to further improve the stability and reliability of the synchronous rotation and rolling motion of the cleaning portion 20 driven by the resilient portion 30, the surface roughness of the outer surface and / or inner surface of the cleaning portion 20 can be set to be smaller than the surface roughness of the outer surface of the resilient portion 30; by setting the roughness of the outer surface of the resilient portion 30 to be relatively large, a greater friction effect can be formed when the outer surface of the resilient portion 30 contacts the inner surface of the cleaning portion 20, and in the process of the resilient portion 30 driving the cleaning portion 20 to perform the synchronous rotation and rolling motion, it is not easy for the cleaning portion 20 to independently rotate and roll relative to the resilient portion 30, thereby improving the consistency of the synchronous rotation and rolling motion of the two. At the same time, the roughness of the outer surface and / or inner surface of the cleaning portion 20 is set to be relatively small, so that a relatively moderate friction cleaning effect can be formed when the cleaning portion 20 contacts the ground for cleaning, which can prevent the problem of the cleaning portion 20 being stuck or rotating and rolling independently relative to the resilient portion 30 due to excessive friction, effectively improving the stability and reliability of the consistency of the synchronous rotation and rolling motion of the cleaning portion 20 driven by the resilient portion 30.

[0130] Or, in this solution, with respect to the structural parts of the cleaning part 20 and the resilient part 30, the cleaning part 20 is configured to be composed of a soft rubber material, and the material of the cleaning part 20 is configured to be a structure of a material different from the material of the resilient part 30; the cleaning part 20 is configured to be composed of a soft rubber material so that the cleaning part 20 has a better softness structure and a better flexibility structure, so that the cleaning part 20 is not easily damaged and can stably contact the ground for friction cleaning, while the resilient part 30 is not composed of a soft rubber material, and it is only necessary to satisfy that the resilient part 30 has a better softness structure, so that the resilient part 30 can form a better elastic driving force on the cleaning part 20 in the radial direction. The composition of different materials enables the resilient part 30 and the cleaning part 20 to better cooperate with each other to achieve the technical effect of the solution.

[0131] Optionally, the cleaning part 20 can be made of materials such as silicone, silicone rubber or rubber, so that the cleaning part 20 has a better soft structure, better wear resistance, and a structure that does not adsorb or absorb liquid. In this way, the cleaning part 20 can be more easily cleaned with clean water. In combination with the curved structure of the cleaning part 20, the outer surface of the cleaning part 20 can be effectively cleaned, so that the cleaning part 20 can be effectively maintained in a clean and dry state for a long time. It can be effectively maintained in a dry state without setting up an air-drying or drying structure. At the same time, the outer surface of the cleaning part 20 can be easily cleaned without setting up a strong scraping structure. The overall structure is simpler, and the structure without strong scratching makes the cleaning part 20 safer and more reliable, and has a longer service life.

[0132] Alternatively, in the present embodiment, for the structural part for cleaning the cleaning section 20, when a liquid supply section is provided to clean the cleaning section 20, the position where the liquid provided by the liquid supply section enters the outer surface of the cleaning section 20 is located at the position of the curved surface structure on the outer surface of the cleaning section 20. A liquid supply section can be provided on the machine body 1, and the liquid supply section is connected to the clean water tank. The clean water in the clean water tank is supplied to the outer surface of the cleaning section 20 through the liquid supply section, that is, clean water. Of course, it can also be a mixture of clean water and cleaning liquid. By setting the clean water supply position at the position of the curved surface structure on the outer surface of the cleaning section 20, the clean water can easily flow along the curved surface structure to flush and clean the dirt on the outer surface of the cleaning section 20. Combined with the fact that there is no structure for hiding dirt and grime at the curved surface structure position on the outer surface of the cleaning section 20, the cleaning section 20 can be easily cleaned. At the same time, the dirty flow on the outer surface of the cleaning section 20 being cleaned can flow along the curved surface structure for convenient collection, thereby effectively improving the collection effect of the dirty flow.

[0133] In this solution, the cleaning component 2 is installed on the machine body 1, and a driving structure is provided on the machine body 1. The driving structure is provided with a motor and a transmission component. The transmission component can be a gear transmission structure or a pulley transmission structure. The motor transmits power to the cleaning component 2 through the transmission component to drive the rotating shaft part 90 to rotate and roll. The rotating shaft part 90 rotates and rolls to drive the rebound part 30 to rotate and roll. The rebound part 30 rotates and rolls to drive the cleaning part 20 to rotate and roll synchronously. The cleaning part 20 rotates and rolls to achieve a cleaning effect on the ground.

[0134] In this solution, the directions of rotation and rolling of the cleaning portion 20 and the rebound portion 30 can be set as needed, such as counterclockwise rotation and rolling motion, or clockwise rotation and rolling motion, and the rotation and rolling directions can be set as needed.

[0135] The cleaning machine of this solution can be a handheld floor scrubber or a self-propelled floor scrubber, and it only needs to use the cleaning component 2 to clean the floor.

[0136] Working principle: The cleaning machine of this scheme realizes the cleaning effect on the ground through the cleaning part 20 on the cleaning component 2. The cleaning part 20 is a curved surface structure when it is not deformed. When it contacts the ground, it can be deformed to form a concave structure and form a cleaning effect on the ground through the concave structure. At the same time, a resilient part 30 is provided to form an elastic driving force on the cleaning part 20. When the concave structure on the cleaning part 20 rebounds to restore its shape to the curved surface structure, the resilient part 30 will form an elastic driving force to push the cleaning part 20 to rebound, and then the concave structure on the cleaning part 20 can effectively rebound to restore its shape to the curved surface structure, and the resilient part 30 can effectively To improve the reliability and stability of the rebound of the cleaning part 20, so that it not only relies on the soft deformation structure of the cleaning part 20 to rebound, but also forms an active and passive combination of rebound effects of the cleaning part 20 under the soft deformation structure of the cleaning part 20 and the elastic driving force of the rebound part 30, so that it can rebound more reliably and stably to restore to the arc surface structure. In this process, it can effectively promote the transfer of dirty liquid and garbage contained in the recessed structure, thereby improving the effect of the cleaning component 2 to drive the transfer of dirty liquid and garbage, preventing the dirty liquid and garbage from falling back to the ground and causing secondary pollution, and greatly improving the overall cleaning effect of the ground.

[0137] Those skilled in the art will understand that the above-mentioned embodiments are specific examples for implementing the present invention, and in actual applications, various changes can be made in form and details without departing from the spirit and scope of the present invention, and all are within the scope of protection of the present invention.
