[0022] In order to make the purpose, technical solution and advantages of the present application more clearly understood, the present application is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and are not used to limit the present application.

[0023] In the related art, the cleaning mechanism installed on the cleaning robot for contacting the ground is relatively simple. For example, when the cleaning mechanism for floor washing is installed on the cleaning robot, it can only perform floor washing operations. When switching to the dust pushing mode, it is necessary to first remove the floor washing cleaning mechanism and replace it with the cleaning mechanism for dust pushing before performing the dust pushing operation. The operation is cumbersome and reduces the user experience. Therefore, the embodiment of the present application provides a cleaning mechanism to solve the above problems.

[0024] like Figure 1 and Figure 2 As shown, a three-dimensional structural diagram of a cleaning mechanism 100 is provided for one embodiment of the present application. The cleaning mechanism 100 includes a roller brush assembly 110, a dust pusher 120, a water suction squeegee 130, a lifting structure 140 and a control system. Figure 1 The direction indicated by the middle arrow is the direction of travel of the cleaning path. The roller brush assembly 110 includes a roller brush 111. In the direction of travel of the cleaning path, the roller brush 111 is located at the front end of the squeegee 130, and the dust pusher 120 is located at the rear end of the squeegee 130, so as to facilitate the compact design of the roller brush 111, the squeegee 130 and the dust pusher 120 to reduce the space occupied by the cleaning mechanism 100 perpendicular to the travel direction. The roller brush 111 is used to clean the surface to be cleaned, the squeegee 130 is located at the rear end of the roller brush 111 and can be used to scrape the sewage on the surface to be cleaned by the roller brush 111 and recycle the sewage, and the dust pusher 120 is used to sweep the dust on the surface to be cleaned or absorb the water stains on the surface to be cleaned.

[0025] The lifting structure 140 is connected to the roller brush assembly 110, the dust pusher 120 and the squeegee 130. The control system is used to control the operation of the lifting structure 140 to drive the roller brush 111, the squeegee 130 and the dust pusher 120 to move to contact the surface to be cleaned, so that after the roller brush 111 cleans the surface to be cleaned at the front end, the squeegee 130 scrapes and absorbs the dirty water on the surface to be cleaned at the rear end and recycles the dirty water.

[0026] When the cleaning mechanism 100 is started, the roller brush 111 and the squeegee 130 can be controlled to contact the surface to be cleaned to enter the cleaning mode; the dust pusher 120 can also be controlled to contact the ground alone to enter the dust pusher mode; or the roller brush 111, the squeegee 130 and the dust pusher 120 can all be controlled to contact the surface to be cleaned. After the roller brush 111 and the squeegee 130 clean the ground at the front end, the dust pusher 120 further absorbs the water vapor on the ground at the rear end to fully clean the surface to be cleaned.

[0027] The cleaning mechanism 100 provided in the embodiment of the present application is integrated with a roller brush assembly 110, a squeegee 130 and a dust pusher 120. When the roller brush 111 and the squeegee 130 of the roller brush assembly 110 are in contact with the surface to be cleaned together, the roller brush 111 enters a cleaning mode, and when the dust pusher 120 is in contact with the surface to be cleaned, the roller brush 111 enters a dust pusher mode, thereby meeting various cleaning needs such as cleaning and dust pushing. Along the direction of travel of the cleaning path, the roller brush 111, the squeegee 130 and the dust pusher 120 are arranged in sequence, and the installation space is rationally planned. By controlling the lifting structure 140 to drive the roller brush 111, the squeegee 130 or the dust pusher 120 to move, the roller brush 111, the squeegee 130 or the dust pusher 120 can be flexibly switched to contact the surface to be cleaned without replacing the cleaning assembly, so as to flexibly switch the working mode and enhance the user experience.

[0028] In some exemplary embodiments, the cleaning mechanism 100 may further include a mounting frame 161 and a plurality of traveling wheels 162 mounted on the mounting frame 161, and the roller brush assembly 110, the squeegee 130 and the dust pusher 120 are arranged between the plurality of traveling wheels 162. The mounting frame 161 and the plurality of traveling wheels 162 provide support for the roller brush assembly 110, the squeegee 130 and the dust pusher 120, and provide movement space for the roller brush assembly 110, the squeegee 130 and the dust pusher 120, thereby facilitating the flexible movement of the cleaning mechanism 100.

[0029] like Figure 3 As shown, the lifting structure 140 includes a first lifting assembly 141 and a second lifting assembly 142 mounted on a mounting frame 161. The first lifting assembly 141 is connected to the squeegee 130 and the roller brush assembly 110. The first lifting assembly 141 is configured to drive the roller brush 111 and the squeegee 130 to move in a direction that is at an angle to the surface to be cleaned until they are in contact with the surface to be cleaned. The second lifting assembly 142 is connected to the dust pusher 120. The second lifting assembly 142 is configured to drive the dust pusher 120 to move in a direction that is at an angle to the surface to be cleaned until they are in contact with the surface to be cleaned. By setting up two sets of lifting structures, the movement of the roller brush 111, the squeegee 130 and the dust pusher 120 are controlled respectively, so as to flexibly switch the roller brush 111, the squeegee 130 or the dust pusher 120 to contact the surface to be cleaned. In the cleaning mode, the first lifting component 141 can be controlled to drive the roller brush 111 and the squeegee 130 to contact the ground to clean the surface to be cleaned. In the dust pushing mode, the second lifting component 142 can be controlled to drive the dust pushing squeegee 120 to remove dust or absorb water from the ground.

[0030] The moving direction of the cleaning mechanism 100 is set according to the situation of the surface to be cleaned. It can be understood that the moving direction is parallel to the surface to be cleaned. In this embodiment, the direction in which the first lifting component 141 drives the roller brush 111 and the squeegee 130 to move to contact the surface to be cleaned is the first direction, and the direction in which the second lifting component 142 drives the dust pusher 120 to move to contact the surface to be cleaned is the second direction. The first direction and the second direction are both set at an angle to the surface to be cleaned, so that the roller brush 111 and the squeegee 130 can move in the opposite direction of the first direction or the dust pusher 120 can move in the opposite direction of the second direction to enter a non-working state and leave the surface to be cleaned, so as to transfer the cleaning mechanism 100.

[0031] There are multiple moving directions in which the lifting structure 140 drives the roller brush 111, the squeegee 130 and the dust pusher 120 to contact the surface to be cleaned. The first direction can be set to be parallel to the second direction, and the first direction and the second direction are both perpendicular to the surface to be cleaned. The first direction, the second direction and the travel direction can also be set to be angled with each other, so that the roller brush 111, the squeegee 130 and the dust pusher 120 can be concentrated in a preset area when not in operation, making the cleaning mechanism 100 compact. For example, the first direction and the second direction are set at an acute angle, and the second direction is perpendicular to the surface to be cleaned. Figure 4 As shown, the direction indicated by arrow S1 is the traveling direction, the direction indicated by arrow S2 is the first direction, the direction indicated by arrow S3 is the second direction, and M is the surface to be cleaned. Under the condition that the roller brush 111, the squeegee 130 and the dust pusher 120 do not interfere with each other, the range in which the roller brush 111, the squeegee 130 or the dust pusher 120 are pushed out can be flexibly adjusted by adjusting the angle range between the first direction and the second direction.

[0032] Specifically, in some exemplary embodiments, the first lifting assembly 141 includes a first electric push rod 1411, which is configured to be telescopic along a first direction at an angle to the surface to be cleaned, and the telescopic end of the first electric push rod 1411 is connected to the roller brush assembly 110 and the squeegee 130. The second lifting assembly 142 includes two groups of second electric push rods, which are configured to be telescopic along a second direction at an angle to the surface to be cleaned, and the two groups of second electric push rods are symmetrically installed on opposite sides of the first electric push rod 1411, and the telescopic ends of the two groups of second electric push rods are connected to the dust pushing squeegee 120. The first electric push rod 1411 and the two groups of second electric push rods are electrically connected to a control system, which can be provided on the mounting frame 161, and the control system is used to control the operation of the first electric push rod 1411 or the two groups of second electric push rods to switch the working mode.

[0033] In the embodiment of the present application, the roller brush 111 and the squeegee 130 both contact the surface to be cleaned and enter the cleaning mode. In order to facilitate the synchronous movement of the roller brush 111 and the squeegee 130 to clean the surface to be cleaned, in some exemplary embodiments, the roller brush assembly 110 also includes a protective cover 170, the roller brush 111 is installed in the protective cover 170, and the squeegee 130 is provided with a connecting assembly 180. The squeegee 130 is movably connected to the protective cover 170 through the connecting assembly 180, and the telescopic end of the first electric push rod 1411 is connected to the protective cover 170, so that the first electric push rod 1411 can drive the roller brush 111 and the squeegee 130 to move together when it is in operation.

[0034] In the direction perpendicular to the direction of travel, the roller brush 111 and the squeegee 130 should have a certain width to improve the working efficiency. Correspondingly, the protective cover 170 should also have a certain width in the direction perpendicular to the direction of travel. In some exemplary embodiments, the first lifting assembly 141 also includes two sets of auxiliary electric push rods 1412 installed on the mounting frame 161. The telescopic ends of the two sets of auxiliary electric push rods 1412 are connected to the protective cover 170. The two sets of auxiliary electric push rods 1412 are also electrically connected to the control system. The control system controls the two sets of auxiliary electric push rods 1412 to cooperate with the first electric push rod 1411 to push the protective cover 170, so as to push the roller brush 111 and the squeegee 130 to contact the surface to be cleaned. The two sets of auxiliary electric push rods 1412 are symmetrically installed on the opposite sides of the first electric push rod 1411, so that the two sets of auxiliary electric push rods 1412 can assist the first electric push rod 1411 in pushing the protective cover 170, ensuring the stability of the protective cover 170 during the pushing process. In some other embodiments, the telescopic ends of the two sets of auxiliary electric push rods 1412 can be connected to the squeegee 130, so that the two sets of auxiliary electric push rods 1412 can independently drive the squeegee 130 to move to contact the surface to be cleaned.

[0035] The roller brush 111 is arranged at the front end of the squeegee 130. In the direction of travel, the protective cover 170 also needs to have a certain width to provide installation space for the roller brush assembly 110 and the squeegee 130. In some exemplary embodiments, the protective cover 170 is symmetrically provided with a plurality of suspension rods 163 movably connected to the mounting frame 161, and the protective cover 170 is also provided with a plurality of support wheels 164 in contact with the surface to be cleaned. When the roller brush 111 and the squeegee 130 are in the storage state, the plurality of suspension rods 163 and the first electric push rod 1411 and the two sets of auxiliary electric push rods 1412 act on the front and rear ends of the protective cover 170 (the front and rear ends of the protective cover 170 along the direction of travel) to maintain the storage stability of the protective cover 170. When the roller brush 111 and the squeegee 130 are in working condition, a plurality of support wheels 164 act on the surface to be cleaned to provide support for the protective cover 170. The first electric push rod 1411 and two sets of auxiliary electric push rods 1412 ensure that the protective cover 170 will not move arbitrarily along the direction of travel, limit the positions of the roller brush 111 and the squeegee 130, and ensure the operating stability of the roller brush 111 and the squeegee 130.

[0036] The roller brush 111 includes a rotating shaft 1112 and a plurality of brush strips 1111 disposed on the rotating shaft 1112 for contacting the surface to be cleaned. The ends of the brush strips 1111 extend out of the opening of the protective cover 170 and contact the surface to be cleaned. The roller brush 111 can better clean the surface to be cleaned when it is in a rotating state. In some exemplary embodiments, the protective cover 170 is further provided with a first rotating driving member, which includes a rotating driving motor 112 and a pulley structure 113. The rotating shaft 1112 is connected to the driving end of the rotating driving motor 112 through the pulley structure 113. The rotating driving motor 112 is connected to a control system. By controlling the rotation of the rotating driving motor 112 to drive the rotating shaft 1112 to rotate, the plurality of brush strips 1111 can continuously contact the surface to be cleaned to clean the surface to be cleaned.

[0037] In some exemplary embodiments, the cleaning mechanism 100 further includes a water delivery component, which is provided with a water outlet 171, and the water outlet 171 can be connected to the water storage component. Along the direction of travel of the cleaning path, the water outlet 171 is located at the front end of the roller brush 111. After the clean water flowing out of the water outlet 171 flows to the surface to be cleaned, the roller brush 111 located at the rear can rotate to drive the clean water to clean the ground, and the squeegee 130 located at the rear of the roller brush 111 continues to scrape and absorb the dirty water.

[0038] There are multiple water outlets 171, which can be arranged on the protective cover 170 and located at the front end of the roller brush 111. The clean water flowing out of the water outlets 171 falls on the surface to be cleaned, and the roller brush 111 can stir the clean water in time to wash the surface to be cleaned. Multiple water outlets 171 can also be arranged near the roller brush 111, so that the clean water flowing out of the water outlets 171 can partially fall on the roller brush 111, so that the roller brush 111 can capture the clean water in time, avoiding the waste caused by the random flow of clean water or secondary pollution of the cleaned area.

[0039] During the travel, in order to prevent the squeegee 130 from being damaged by hard contact with obstacles and to improve the flexibility of the squeegee 130 during the curve movement such as turning, the squeegee 130 is movably mounted on the protective cover 170 through the connecting assembly 180. Specifically, Figure 1 As shown, the connecting assembly 180 may include a connecting plate 181 and two telescopic springs 182, one end of the connecting plate 181 is fixedly connected to the squeegee 130, and the other end of the connecting plate 181 is rotatably connected to the protective cover 170 with a direction perpendicular to the surface to be cleaned as the central axis, and the two ends of the telescopic spring 182 are respectively connected to the squeegee 130 and the protective cover 170, and the two telescopic springs 182 are symmetrically installed on both sides of the connecting end of the connecting plate 181 and the protective cover 170. The two telescopic springs 182 limit the range of movement of the squeegee 130 and drive the squeegee 130 to reset.

[0040] In some exemplary embodiments, the squeegee 130 includes a plate-shaped water-absorbing mounting plate 131 and a wiper blade 132 wrapped around the outer periphery of the water-absorbing mounting plate 131. The telescopic end of the first electric push rod 1411 is connected to the water-absorbing mounting plate 131. The end of the wiper blade 132 extends out of the surface of the water-absorbing mounting plate 131 and contacts the surface to be cleaned. The surface of the wiper blade 132 and the surface of the water-absorbing mounting plate 131 jointly form a cleaning cavity 133. The water-absorbing mounting plate 131 is provided with a sewage outlet 1311 connected to the cleaning cavity 133. The sewage outlet 1311 is used to connect to an external suction device. The external suction device is controlled to extract the gas in the cleaning cavity 133, so that the cleaning cavity 133 is in a negative pressure state, so that the sewage gathered at the front end of the wiper blade 132 can be pressed into the cleaning cavity 133, and then sucked away from the sewage outlet 1311, so that the squeegee 130 can continuously scrape and suck the sewage to prevent the sewage from flowing freely.

[0041] The wiper blade 132 can be made of a deformable material, for example, the wiper blade 132 can be made of rubber. When the wiper blade 132 contacts the surface to be cleaned, the wiper blade 132 deforms to contact the surface to be cleaned and better scrapes the sewage. At the same time, under the action of the negative pressure in the cleaning cavity 133, the sewage can be squeezed into the cleaning cavity 133 from the deformed end of the wiper blade 132.

[0042] The water absorption mounting plate 131 can be set to be a crescent-shaped shape protruding in a direction away from the roller brush 111, and the wiper blade 132 is covered on the outer periphery of the water absorption mounting plate 131 to form a crescent-shaped cleaning chamber 133, so that the sewage scraped by the wiper blade 132 can be gathered from the outer periphery to the middle of the squeegee 130, which is convenient for recycling sewage and improving cleaning efficiency. Further, the wiper blade 132 may include a first scraper blade 1321 and a second scraper blade 1322 covered on the outer periphery of the water absorption mounting plate 131, the first scraper blade 1321 is installed on the side of the water absorption mounting plate 131 facing the roller brush 111, and the second scraper blade 1322 is installed on the side of the water absorption mounting plate 131 away from the roller brush 111, and the two ends of the first scraper blade 1321 and the two ends of the second scraper blade 1322 are spaced to form a suction port 132a connected to the cleaning chamber 133, and the sewage can enter the cleaning chamber 133 from the suction port 132a, which is convenient for recycling sewage. When the cleaning mechanism 100 is working, the water absorption mounting plate 131 can be adjusted to be parallel to the surface to be cleaned, and the first scraper 1321 and the second scraper 1322 can form an angle with the surface to be cleaned. Specifically, the present application does not limit the installation method of the water absorption mounting plate 131, the first scraper 1321 and the second scraper 1322, as long as the first scraper 1321 and the second scraper 1322 are in contact with the surface to be cleaned and can scrape the sewage on the surface to be cleaned.

[0043] The dust pusher 120 includes a plate-shaped dust pusher mounting plate 122 and a plurality of dust pusher strips 121 mounted on the dust pusher mounting plate 122, and the ends of the dust pusher strips 121 are used to contact the surface to be cleaned. The plurality of dust pusher strips 121 can be made of soft and water-absorbent materials, for example, the dust pusher strips 121 can be made of cloth strips, water-absorbent foam, and the like. The plate-shaped dust pusher mounting plate 122 can be adjusted to be parallel to the surface to be cleaned, so that the dust pusher strips 121 can contact the surface to be cleaned more fully.
