[0067] In this solution, the first scraper 401 is used to scrape the dirty liquid from the suction cylinder 201. The main structure is that when the suction cylinder 201 is installed in place and the first cover assembly 4 is installed in place, the first scraper 401 is configured to extend into the inner side of the outer surface of the suction cylinder 201 to form an interference structure with the suction cylinder 201, so that the dirty liquid absorbed by the suction cylinder 201 is scraped off; when the first cover assembly 4 is installed in place, the first scraper 401 extends into the lower cavity 101 and extends into the inner side of the outer surface of the suction cylinder 201 to form a structure inserted into the inner side of the outer surface of the suction cylinder 201 and then form an interference structure. Under the interference structure and when the suction cylinder 201 rolls, the part of the first scraper 401 inserted into the suction cylinder 201 forms an interference scraping structure with the suction cylinder 201 to scrape off the dirty liquid and dirt. The dirty liquid and dirt will be separated from the suction cylinder 201 to be absorbed and collected.

[0068] In this solution, the second scraping portion 501 is used to scrape the dirty liquid from the scraping cylinder 301. The main structure is that when the scraping cylinder 301 is installed in place and the second cover assembly 5 is installed in place, the second scraping portion 501 is configured to be in contact and press-fit with the outer surface of the scraping cylinder 301, so that the dirt adsorbed on the outer surface of the scraping cylinder 301 is scraped off; when the second cover assembly 5 is installed in place, the end position of the second scraping portion 501 is in contact with the outer surface of the scraping cylinder 301 and forms a contact and press-fit structure, which will make The outer surface of the scraper cylinder 301 is deformed to form a concave structure, and the second scraping portion 501 contacts the scraper cylinder 301 on the outer surface at the position of the concave structure. When the scraper cylinder 301 rolls, the second scraping portion 501 contacts along the outer surface of the scraper cylinder 301 and forms a relative sliding state, so as to scrape off the dirty liquid and dirt adsorbed or adhered to the outer surface of the scraper cylinder 301 to separate them, so that the dirty liquid and dirt are separated from the outer surface of the scraper cylinder 301 and are absorbed and collected.

[0069] 1 and 10. In the embodiment of the present invention, a sewage suction port 103 is provided on the device body 1. The sewage suction port 103 is configured to be connected to the lower chamber 101. The sewage suction port 103 is mainly used for dirty liquid and dirt to enter the sewage suction port 103 from the suction cylinder 201, the scraping cylinder 301 and the lower chamber 101 and finally be collected in the cleaning device. The sewage suction port 103 is connected to the sewage suction channel to realize the collection of dirty liquid and dirt. When the cleaning device is started, under the action of suction, a suction force is formed to move and collect the dirty liquid and dirt. At the same time, the suction cylinder 201 and the scraping cylinder 301 will also generate a throwing force during the rolling motion to move the dirty liquid and dirt in the rotational rolling direction. Combined with the structure of the first scraping part 401 and the second scraping part 501, the collection and processing of dirty liquid and dirt is finally realized when the suction cleaning component 2 and the first cover component 4 are installed in place, and the collection and processing of dirty liquid and dirt is realized when the scraping cleaning component 3 and the second cover component 5 are installed in place.

[0070] In order to further improve the collection effect of dirty liquid and dirt, in this solution, the vertical height distance H2 from the position where the second scraping part 501 and the scraping cylinder 301 contact each other to the dirt suction port 103 is set to be smaller than the vertical height distance H1 from the position where the first scraping part 401 and the suction cylinder 201 interfere with each other to the dirt suction port 103. In this way, when the second scraping part 501 scrapes and separates the dirt on the scraping cylinder 301, it can fall back and move to the dirt suction port 103 for collection within a shorter distance. It can be understood that the fluidity of the dirty liquid is better than the fluidity of the dirt. By setting the vertical height distance H2 to be relatively small, the dirt can be better collected. At the same time, by setting the vertical height distance H1 to be relatively large, it is achieved that the collection effect of the dirty liquid on the suction cylinder 201 will not be affected, thereby achieving better collection of the dirty liquid when the suction cylinder 201 is installed in place, and achieving better collection of the dirty liquid when the suction cylinder 201 is installed in place. It is achieved that the scraping cylinder 301 can be better collected when it is installed in place.

[0071] In this solution, a sewage tank is also provided, which is connected to the sewage suction port 103 through a pipe, so that the dirty liquid and dirt are collected in the sewage tank. At the same time, a suction piece is provided to suck the dirty liquid and dirt into the sewage tank for collection.

[0072] Optionally, the suction member is configured as a fan or a vacuum pump to generate suction to absorb the dirty liquid and dirt and collect them into the sewage tank.

[0073] In this solution, in order to better collect dirty liquid and dirt, the angle A1 formed between the first scraping portion 401 and the horizontal plane P where the central axis of the suction cylinder 201 is located is set to be smaller than the angle A2 formed between the second scraping portion 501 and the horizontal plane Q where the central axis of the scraping cylinder 301 is located, and the angle A2 is set to be greater than or equal to 45 degrees and less than or equal to 75 degrees. This is mainly because the angle A1 formed between the plane parallel to the protruding direction of the first scraping portion 401 and the horizontal plane P is set to be relatively small so that the scraped dirty liquid can be effectively concentrated to flow back downward, thereby achieving better absorption and collection of the dirty liquid, and the angle A2 formed between the plane parallel to the protruding direction of the second scraping portion 501 and the horizontal plane Q is set to be relatively large so as to prevent dirt accumulation and blockage during the scraping process, thereby achieving better absorption and collection of the dirt.

[0074] Preferably, the angle A1 is set to be less than or equal to 40 degrees and greater than or equal to 20 degrees.

[0075] Preferably, the angle A2 is set to be greater than or equal to 60 degrees and less than or equal to 70 degrees.

[0076] In this solution, in order to further improve the effect of the first scraping portion 401 in scraping away dirty liquid from the suction cylinder 201 and the effect of the second scraping portion 501 in scraping away dirt from the scraping cylinder 301, the first scraping portion 401 is configured to have a structure in which the thickness value gradually decreases in the convex direction and the second scraping portion 501 is configured to have a structure in which the thickness value gradually increases in the convex direction; the thickness value structure of the first scraping portion 401 enables the end position of the first scraping portion 401 to better extend into the inner side of the outer surface of the suction cylinder 201 to form an interference structure, thereby better and more effectively scraping away the dirty liquid absorbed in the suction cylinder 201; the thickness value structure of the second scraping portion 501 enables the end position of the second scraping portion 501 to form a contact pressure structure with the outer surface of the scraping cylinder 301 to increase the contact area, thereby better and more effectively scraping away the dirty liquid and dirt adsorbed on the outer surface of the scraping cylinder 301; as a whole, the cleaning effect of the suction cylinder 201 and the scraping cylinder 301 is improved.

[0077] And / or, in order to further improve the effect of the first scraping portion 401 on scraping away dirty liquid on the suction cylinder 201 and to improve the effect of the second scraping portion 501 on scraping away dirt on the scraping cylinder 301, by setting the end position of the first scraping portion 401 in the convex direction to be a V-shaped structure and the end position of the second scraping portion 501 in the convex direction to be a U-shaped structure, the V-shaped structure of the first scraping portion 401 enables the end position of the first scraping portion 401 to better extend into the inner side of the outer surface of the suction cylinder 201 to form an interference structure, thereby better scraping away the dirty liquid absorbed in the suction cylinder 201 effectively; the U-shaped structure of the second scraping portion 501 enables the second scraping portion 401 to better scrape away the dirty liquid absorbed in the suction cylinder 201 effectively; The end position of the part 501 can form a contact pressure-connected structure with the outer surface of the scraper cylinder 301 to increase the contact area, and at the same time form a better contact sliding effect between the two. The scraper cylinder 301 continuously rotates and rolls so that the end position of the second scraper part 501 can better contact and slide relatively on the outer surface of the scraper cylinder 301, and in the process of sliding, the dirt can be scraped and separated from the outer surface of the scraper cylinder 301, thereby better scraping off the dirty liquid and dirt adsorbed on the outer surface of the scraper cylinder 301; the overall cleaning effect of the suction cylinder 201 and the scraper cylinder 301 is improved.

[0078] In this solution, with respect to the structural part of the suction cylinder 201, the suction cylinder 201 is configured to be composed of a fur layer to form a soft structure and a water-absorbent structure that can absorb dirty liquid. The fur layer or fluff layer structure enables the suction cylinder 201 to have a better soft structure to contact and fit the ground to form a cleaning effect. At the same time, it also enables the suction cylinder 201 to have a better water-absorbent effect, so that it can absorb dirty liquid, i.e. sewage, to reduce the residual sewage on the ground, and at the same time, it can clamp the dirt and dirt on the ground to achieve a cleaning effect on the ground. The sewage absorbed and the clamped dirt on the suction cylinder 201 can be scraped off by the first scraping part 401. At the same time, combined with the cleaning equipment, clean water will be provided to the ground or to the suction cylinder 201 during operation, so as to achieve a cleaning effect on the suction cylinder 201.

[0079] In this solution, for the structural part of the scraping cylinder 301, the scraping cylinder 301 is set to be composed of a rubber material to form a soft and deformable structure and a hydrophobic structure that does not absorb dirty liquid. The composition of the rubber material makes the scraping cylinder 301 have a good soft and deformable effect, so that the scraping cylinder 301 can be deformed when it contacts the ground, and then deformed during the process of contacting the ground to scrape off and drive the transfer of dirt. At the same time, the scraping cylinder 301 will not absorb sewage in the process of cleaning the ground, but only scrape the dirty liquid and dirt off the ground and drive and transfer them, achieving a better cleaning effect on the ground. At the same time, combined with the cleaning equipment, clean water will be provided to the ground or to the suction cylinder 201 during work, which can achieve a cleaning effect on the suction cylinder 201. When the cylinder 301 contacts the ground for cleaning, a part of the outer surface of the scraping cylinder 301 will be deformed to form a scraping portion with a concave structure to realize the cleaning structure of the ground. When the scraping cylinder 301 contacts the ground during the rolling motion, a certain pressing force will be formed. Under the action of the pressing force and the rotational rolling force, the part of the scraping cylinder 301 that contacts the ground will be deformed upward to form a concave structure. The concave structure forms a scraping portion, which drives and transfers dirty liquid and dirt, and drives the dirty liquid and dirt from the ground to be collected into the cleaning equipment. When the concave structure continues to roll with the scraping cylinder 301, it will no longer contact the ground and restore its shape. In the process of restoring the shape, it pushes the dirty liquid and dirt to be transferred, thereby realizing the effect of collecting the dirty liquid and dirt.

[0080] In this solution, when both the suction cylinder 201 and the scraping cylinder 301 are of soft structure, the softness of the suction cylinder 201 is set to be greater than the softness of the scraping cylinder 301, so that the suction cylinder 201 can better absorb the dirty liquid and the scraping cylinder 301 can better drive and transfer the dirt, thereby achieving a better cleaning effect on the floor. At the same time, the dirty liquid and dirt on the suction cylinder 201 and the scraping cylinder 301 can also be better scraped off by the first scraping part 401 and the second scraping part 501 respectively, thereby improving the cleaning effect of the suction cylinder 201 and the scraping cylinder 301.

[0081] Optionally, the rubber material structure of the scraping tube 301 can be made of materials such as silica gel and silicone rubber, so that the scraping tube 301 has a soft and deformable structure and a hydrophobic structure.

[0082] In this solution, in order to ensure that the first cover assembly 4 is installed in place when the suction cleaning component 2 is installed, or to ensure that the second cover assembly 5 is installed in place when the scraping cleaning component 3 is installed, a sensor is provided on the device body 1, and the sensor is used for detection. The sensor is electrically connected to the control unit, and the control unit can make a judgment based on the feedback information of the sensor, and when the suction cleaning component 2 is installed in place and the first cover assembly 4 is installed in place, it is configured to be a touch structure for the sensor, or when the scraping cleaning component 3 is installed in place and the second cover assembly 5 is installed in place, it is configured to be a touch structure for the sensor, thereby forming a detection and judgment structure to prevent the second cover assembly 5 from being installed in place when the suction cleaning component 2 is installed, and to prevent the first cover assembly 4 from being installed in place when the scraping cleaning component 3 is installed. At the same time, a voice unit can also be configured to prompt the current installation situation, and when the user does not perform the corresponding installation, it can remind the user of installation errors.

[0083] Among them, the sensing member can be set to be a raised structure, and a socket part with a central through structure can be set on the suction and wiping cleaning component 2. When the suction and wiping cleaning component 2 is installed in place, the sensing member is socketed in the socket part and extends above the socket part. At this time, when the first cover component 4 is installed in place, a pressure-contact structure can be formed on the sensing member, thereby triggering the sensing member. At this time, when the second cover component 5 is installed in place, a pressure-contact structure will not be formed on the sensing member, and the second cover component 5 will not contact the sensing member, thereby achieving the situation that the suction and wiping cleaning component 2 and the first cover component 4 are installed in place, and the cleaning device can be controlled to start; of course, if the sensing member is not triggered, the user can be prompted to install incorrectly or the first cover component 4 is not installed in place. At this time, the cleaning device cannot start to control the rolling movement of the suction and wiping cleaning component 2.

[0084] Among them, the sensing member can be set to be a raised structure, or a socket part with a central through structure can be set on the scraping and cleaning component 3. When the scraping and cleaning component 3 is installed in place, the sensing member is socketed in the socket part and extends above the socket part. At this time, when the second cover component 5 is installed in place, a pressure-contact structure can be formed on the sensing member, thereby triggering the sensing member. At this time, when the first cover component 4 is installed in place, a pressure-contact structure will not be formed on the sensing member, and the first cover component 4 will not contact the sensing member, thereby achieving the result that the scraping and cleaning component 3 and the second cover component 5 are installed in place, and the cleaning device can be controlled to start; of course, if the sensing member is not triggered, the user can be prompted to install incorrectly or the second cover component 5 is not installed in place. At this time, the cleaning device cannot start to control the rolling movement of the scraping and cleaning component 3.

[0085] Optionally, the sensing element is configured as a micro switch or an infrared sensor.

[0086] Optionally, the number of sensors can be set to one or two. When two sensors are set, the positions of the two sensors are not set at the same position, so that one of the sensors can detect whether the suction cleaning component 2 and the first cover component 4 are installed in place, and the other sensor can detect whether the scraping cleaning component 3 and the second cover component 5 are installed in place.

[0087] In this solution, the cleaning equipment can be set as a handheld floor scrubber, a handheld floor mop, etc., or it can be set as a self-moving floor scrubber, a self-moving floor mop, etc.

[0088] Anything not mentioned in this plan can be achieved by adopting or drawing on existing technologies.

[0089] Working principle: The cleaning device of this scheme is provided with a suction cleaning component 2, a scraping cleaning component 3, and is correspondingly provided with a first cover component 4 and a second cover component 5. When the user chooses to install the suction cleaning component 2 in place, the first cover component 4 can be installed in place. At this time, the first cover component 4 presses the suction cleaning component 2 to limit the position on the device body 1, and at the same time forms a structure for scraping the dirty liquid on the suction cylinder 201 through the first scraping part 401. During the process of cleaning the floor, the first scraping part 401 continuously scrapes the dirty liquid on the suction cylinder 201, so that the suction cylinder 201 can be cleaned in combination with the structure of supplying clean water; when the user chooses to install the scraping cleaning component 3 in place, the second cover component 5 can be installed in place. At this time, the second cover component 5 scrapes the cleaning component 2 The cleaning component 3 is crimped and limited on the device body 1, and at the same time, a structure for scraping dirt from the scraping cylinder 301 is formed through the second scraping part 501. During the process of cleaning the ground, the second scraping part 501 continues to scrape the dirt on the scraping cylinder 301, so that the scraping cylinder 301 can be cleaned in combination with the structure of supplying clean water; in the structure of this scheme, the first cover component 4 can be used to independently crimp and fix the suction and wiping cleaning component 2 and scrape off the dirty liquid, and the second cover component 5 can be used to independently crimp and fix the scraping and cleaning component 3 and scrape off the dirt, so that the suction and wiping cylinder 201 and the scraping cylinder 301 can be scraped off dirt and dirt respectively, and then can be effectively cleaned, and it is not easy to cause secondary pollution to the ground, which greatly improves the user experience.
