[0002] With the continuous development of robot technology, cleaning robots are widely used. Cleaning equipment includes roller brushes, fan modules and dust collection devices, etc. There is also a dust collection port at the bottom of the cleaning equipment. When the cleaning equipment is cleaning, the roller brush sweeps the garbage to the dust collection port, and then the fan module generates negative pressure to suck the garbage into the dust collection device.

[0003] However, the negative pressure suction at the dust collection port depends on the power of the fan module.

[0064] In order to enable those skilled in the art to better understand the solution of the present application, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application.

[0065] The embodiments described in this application are only a part of the embodiments of this application, not all the embodiments. Based on the embodiments in this application, all other embodiments obtained by those skilled in the art without making creative work are within the scope of protection of this application. The "including" mentioned in the entire specification and claims is an open term, so it should be interpreted as "including but not limited to". "Approximately" means that within an acceptable error range, those skilled in the art can solve the technical problems within a certain error range and basically achieve the technical effects. In addition, in the embodiments of this application, multiple refers to two or more. In the absence of mutual contradiction, those skilled in the art can combine and combine the different embodiments or examples described in this specification and the features of different embodiments or examples. The descriptions of "first", "second", etc. in this article are used to distinguish different directions, structures, components, etc., and do not represent the order of precedence.

[0066] With the continuous development of cleaning robot technology, in order to meet the cleaning needs of large areas of ground such as shopping malls, hotels, and office buildings, a cleaning device that can autonomously move in an indoor environment and perform cleaning work is widely used. This cleaning equipment can not only improve economic efficiency, but also reduce the workload of cleaning staff. However, due to the particularity of the site, the noise generated by the cleaning equipment during cleaning must be controlled within a smaller range. The noise generated by the cleaning equipment is related to the power of the suction motor on the cleaning equipment. The greater the power of the suction motor, the greater the suction force it generates, and of course the greater the noise generated by the suction motor. If the power of the suction motor is reduced in order to reduce noise, it is likely that the suction force will not be able to absorb and collect all the heavy garbage on the ground.

[0067] In addition, due to the complex ground environment in shopping malls, hotels, office buildings and other areas, there are not only more obstacles on the ground, but also more pedestrians walking back and forth, and the cleaning equipment faces a great test in terms of safety. Due to the complexity of the ground environment, the mopping and washing components of the cleaning equipment are easily entangled with hair and garbage when cleaning. The mopping and washing components of the cleaning equipment are also easy to collide with obstacles during the movement of the cleaning equipment. These problems will not only affect the cleaning efficiency of the cleaning equipment, but will also seriously affect the service life of the cleaning equipment. Obviously, these problems are urgent and need to be solved.

[0068] In order to solve the above problems, the present application provides a dust bucket assembly, a roller brush assembly and a cleaning device. The following describes each assembly and the cleaning device through detailed embodiments.

[0069] Before introducing each component, first give a brief introduction to the overall structure of the cleaning equipment.

[0070] See also Figure 1 , Figures 13 to 18In one embodiment of the present application, a cleaning device is provided, which includes a chassis 101, a roller brush assembly 2, a dust bucket assembly 1, and a fan module 3. A housing 102 is provided on the chassis 101 to form a device body 100 of the cleaning device, and each component of the cleaning device is respectively arranged on the chassis 101 in the device body 100.

[0071] Taking the device body 100 as a square structure as an example, the shell 102 includes a shell body 131, a front shell 132, a rear shell 133 and a top shell 134. The shell body 131 is equivalent to the bracket of the entire shell 102. In the front and rear directions of the device body 100, the front shell 132 is connected to the front side of the shell body 131, and the rear shell 133 is connected to the rear side of the shell body 131. The front side of the device body 100 is also provided with a collision plate shell 136, which is located below the front shell 132 and is movably connected to the shell body 131. The collision plate shell 136 is a U-shaped structure, which is wrapped around the periphery of the front end of the chassis 101. A collision detection sensor can be set on the collision plate shell 136. When the collision plate shell 136 collides with an obstacle, the collision detection sensor will be triggered, and the cleaning device can control the cleaning device to stop in time according to the collision signal, thereby avoiding damage to the cleaning device.

[0072] The housing body 131 is provided with a roller brush maintenance door 137 at a position corresponding to the roller brush assembly 2. The roller brush maintenance door 137 can be opened to maintain the roller brush assembly 2 in the device body 100. In addition, to facilitate the disassembly and assembly of the dust bucket assembly 1, a top cover 135 is provided on the top housing 134. The dust bucket assembly 1 can be conveniently disassembled and assembled by opening the top cover 135.

[0073] In order to make the cleaning device have multiple functions and be more intelligent. Various components and modules are respectively arranged on the chassis 101. For example, there are a traveling module, a roller brush assembly 2, a side brush assembly 25 and a mopping assembly 9 under the chassis 101. The traveling module can be a three-wheel structure or a four-wheel structure. Taking the traveling module as a three-wheel structure as an example, it includes a universal wheel 42 and a driving wheel 41. Along the forward direction of the device body 100 ( Fig.15 The side brush assembly 25 (in the direction of the middle arrow X), the universal wheel 42, the roller brush assembly 2, the driving wheel 41 and the mopping assembly 9 are sequentially arranged at the bottom of the chassis 101 from front to back.

[0074] When one side brush assembly 25 is provided on the chassis 101, the side brush assembly 25 is provided at a corner of the front end of the chassis 101. When two side brush assemblies 25 are provided on the chassis 101, the roller brush assembly 2 is respectively provided at the upper left corner and the upper right corner of the front end of the chassis 101. The bristles of the side brush assembly 25 extend out of the chassis 101. As the side brush assembly 25 rotates, the side bristles can sweep the garbage outside the chassis 101 area to the bottom of the chassis 101, and then the roller brush assembly 2 sweeps and collects it. By arranging the side brush assembly 25 at the corners of the front end of the chassis 101, the cleaning device can achieve edge cleaning.

[0075] See also Fig.15 The mopping assembly 9 is arranged at the rear end of the chassis 101, and a mopping member 91 is arranged on the mopping assembly 9, and the mopping member 91 includes but is not limited to: a rag strip, a rotatable rag plate, a cleaning roller, etc. The mopping member 91 can mop the ground, so as to wet-wash the stains on the ground.

[0076] See also Figures 15 to 18 , a front bracket 103, a power battery 43, a dust bucket assembly 1, a fan module 3 and a rear bracket 104 are arranged above the chassis 101. The front and rear ends of the chassis 101 are in a stepped shape, and the rear end of the chassis 101 is higher than the front end of the chassis 101. The front bracket 103 is arranged at the front end of the chassis 101, and the rear bracket 104 is arranged at the rear end of the chassis 101. Along the front and rear direction of the chassis 101, the dust bucket assembly 1 is arranged in the middle position of the chassis 101. A through opening is provided on the chassis 101, and the bottom end of the dust bucket assembly 1 can pass through the opening of the chassis 101 and extend to the bottom of the chassis 101. The dust collecting port on the dust bucket assembly 1 is arranged opposite to the roller brush assembly 2 below the chassis 101.

[0077] The power battery 43 is located between the front bracket 103 and the dust bucket assembly 1, and is used to provide working power for the cleaning device. The fan module 3 is arranged behind the dust bucket assembly 1, and the fan module 3 is connected to the chassis 101 between the dust bucket assembly 1 and the rear bracket 104. The suction port of the fan module 3 is connected to the dust bucket assembly 1, and is used to draw negative pressure inside the dust bucket assembly 1. With the rotation and cleaning of the roller brush assembly 2 and the negative pressure suction force generated by the fan module 3, garbage collection and transportation are realized.

[0078] The wet mop-wash component 9 will always leave water stains on the ground when mopping the ground. As the cleaning area expands, the cleaning liquid on the mop-wash component 9 will inevitably become less and less, and then the cleaning power of the mop-wash component 9 will continue to decrease. In order to ensure that the mop-wash component 9 always has a good cleaning power. In one embodiment provided in the present application, the cleaning equipment also includes a clean water tank and a water supply module. The water supply module is connected to the clean water tank and the mop-wash component 9 through pipes, respectively, and the water supply module can supply the cleaning liquid in the clean water tank to the mop-wash component 9. The water supply module can be a water pump, which continuously pumps the cleaning liquid stored in the clean water tank to the mop-wash component 9, so that the mop-wash component 9 can always be in a wet state.

[0079] Furthermore, when the mopping and washing component 9 is mopping and washing the floor, the mopping and washing component 9 may be smeared with dirt, that is, the dirt on the mopping and washing component 9 is continuously accumulated, and then the dirt on the mopping and washing component 9 will smear the clean floor, causing the cleaning failure. In order to avoid this situation, in one embodiment provided in the present application, the cleaning device also includes a sewage tank, which is connected to the mopping and washing component 9 through a water absorption module. The water absorption module can suck the sewage on the mopping and washing component 9 into the sewage tank, and the sewage tank can temporarily store the sewage to increase the cleaning endurance of the cleaning device.

[0080] The following is a brief introduction to how the mop-wash assembly 9 performs self-cleaning.

[0081] A dirt sensor is provided on the mop washing part 91 of the mop washing assembly 9. When the dirt sensor detects that a large amount of dirt has accumulated on the mop washing part 91, the water supply module increases the water supply to simply rinse the dirty mop washing part 91 to dissolve the dirt. Then the water absorption module increases the water absorption power to suck the sewage on the mop washing part 91 into the sewage tank. After the water supply module increases the water supply, the mop washing part 91 will inevitably be excessively wet, and the mop washing part 91 will leave a lot of water stains on the ground after mopping the ground. In the technical solution provided in the present application, a scraping strip is also provided at the rear of the mop washing part 91, and the scraping strip can scrape the ground mopped by the mop washing part 91 to gather a large amount of water stains remaining on the ground, and then the water absorption module collects them clean. Through this technical solution, the mop washing part 91 can not only perform self-cleaning while mopping the ground, but also avoid a large amount of water stains remaining on the ground.

[0082] The roller brush assembly 2 has two main functions. For garbage with a larger mass, the roller brush assembly 2 can directly clean it. During the rotation process, the roller brush assembly 2 can also pat the ground to dust off the smaller mass garbage, which is convenient for being sucked away by the negative pressure suction force generated by the fan module 3. The roller brush assembly 2 is arranged opposite to the dust collecting port on the dust bucket assembly 1, and the dust collecting port is close to the roller brush assembly 2. The roller brush assembly 2 can directly clean the larger mass garbage into the dust collecting port during the rotation and cleaning process. In addition, the negative pressure suction force at the dust collecting port can directly act on the surrounding area of ​​the roller brush assembly 2, thereby improving the cleaning efficiency of the fan module 3.

[0083] During the cleaning process of the cleaning device, the roller brush assembly 2 and the fan module 3 usually work together. When the roller brush assembly 2 rotates and sweeps and the fan module 3 generates a negative pressure suction force. The heavier garbage on the cleaning surface (floor, tile floor, carpet floor, etc.) is swept into the first dust collecting chamber of the dust bucket assembly 1 by the roller brush assembly 2, and the other lighter garbage is sucked into the second dust collecting chamber. Specifically, when the fan module 3 is running at low power, some of the heavier garbage cannot be directly sucked into the dust bucket assembly 1. In the technical solution of the present application, by making the roller brush assembly 2 and the dust collecting port relatively arranged, during the process of the roller brush assembly 2 rotating and sweeping, these heavier garbage can be directly swept into the first dust collecting chamber of the dust bucket assembly 1. As for the other part of the smaller garbage, the suction force generated by the low-power fan module 3 can directly suck it into the first dust collecting chamber or the second dust collecting chamber. Alternatively, the roller brush assembly 2 dusts up these smaller garbage, and then is sucked into the first dust collecting chamber or the second dust collecting chamber by the suction force.

[0084] In the technical solution provided in the present application, the roller brush assembly 2 on the cleaning device can not only clean the ground, but the mopping assembly 9 arranged at the rear end of the device body 100 can also mop and wash the cleaned ground. The cleaning device not only has a good cleaning effect, but can also be adapted to the cleaning of various ground surfaces. The dust collecting port of the dust bucket assembly 1 is arranged relative to the roller brush assembly 2. When the cleaning roller brush 27 rotates, a part of the heavy garbage can be swept into the first dust collecting chamber of the dust bucket assembly 1. The suction force generated by the low-power fan module 3 can suck and collect the other part of the lighter garbage into the second dust collecting chamber of the dust bucket assembly 1. This cleaning device can take into account both noise control and cleaning and collecting all the garbage on the ground.

[0085] The dust bucket assembly 1 provided in the present application is described in detail below through a detailed embodiment.

[0086] Figure 1 A cross-sectional view of a cleaning device provided in an embodiment of the present application, Figure 2A cross-sectional view of a dust bucket assembly and a schematic diagram of a first airflow path provided in an embodiment of the present application. Figure 1 and Figure 2 In one embodiment of the present application, a dust bucket assembly is provided. This dust bucket assembly 1 is suitable for a cleaning device having a roller brush assembly 2 and a fan module 3. The dust bucket assembly 1 includes: a barrel body 11, a dust collecting port 12 and a dust collecting cavity. The dust collecting port 12 is located on the side wall at the bottom end of the barrel body 11. The collected garbage can enter the dust collecting cavity of the dust bucket assembly 1 through the dust collecting port 12 to be temporarily stored in the dust collecting cavity. Normally, the dust bucket assembly 1 can be detachably connected to the device body 100 of the cleaning device. When enough garbage is collected in the dust bucket assembly 1, the dust bucket assembly 1 can be directly disassembled for cleaning.

[0087] In order to facilitate the storage of different types of garbage, the dust bucket assembly 1 has multiple dust collecting chambers, and different dust collecting chambers can be used to temporarily store garbage. Figure 2 For example, the dust barrel assembly 1 has two dust collecting chambers. The first dust collecting chamber 13 is arranged beside the dust collecting port 12 and is connected to the dust collecting port 12. The garbage can directly enter the first dust collecting chamber 13 through the dust collecting port 12. The second dust collecting chamber 14 is connected to the first dust collecting chamber 13 through the dust collecting channel 15. The garbage can enter the dust collecting channel 15 through the dust collecting port 12 and then enter the second dust collecting chamber 14. Alternatively, the garbage first enters the first dust collecting chamber 13 through the dust collecting port 12 and then enters the second dust collecting chamber 14 after passing through the dust collecting channel 15.

[0088] The fan module 3 is mainly used to generate negative pressure in the dust collecting chamber of the dust bucket assembly 1, and then generate a suction airflow at the dust collecting port 12. As the suction airflow flows, the garbage on the surface to be cleaned (ground, carpet, wooden floor, etc.) can be carried to the first dust collecting chamber 13 and / or the second dust collecting chamber 14 by the suction airflow. Figure 3 In the technical solution of the present application, the fan module 3 is connected to the second dust collecting chamber 14, which will generate negative pressure in the second dust collecting chamber 14 and then generate a suction airflow to achieve garbage collection.

[0089] When the cleaning device is performing cleaning operations, the roller brush assembly 2 and the fan module 3 will work simultaneously, the roller brush assembly 2 performs rotary cleaning, and the fan module 3 generates a suction airflow, and the two work together to collect the garbage into the dust collection chamber. The rotary cleaning of the roller brush assembly 2 has multiple functions. First, the rotary cleaning of the roller brush assembly 2 can directly sweep the garbage into the dust collection port 12, or sweep it to the vicinity of the dust collection port 12; second, the rotary cleaning of the roller brush assembly 2 can also achieve patting the ground, thereby dusting off the dust and garbage on the ground, and then the suction airflow sucks and collects the garbage.

[0090] Usually, the main function of the roller brush on some ordinary cleaning equipment is to sweep the garbage on the surface to be cleaned to the dust collection port 12, and then rely on the strong suction force generated by the fan module 3 to suck and collect the garbage. The roller brush cannot directly sweep the garbage into the dust bin. Therefore, the ability of the cleaning equipment to collect garbage is mainly determined by the power of the fan module 3. When the power of the fan module 3 is greater, the suction airflow is also stronger, and the garbage with larger mass on the surface to be cleaned can be sucked into the dust bin assembly 1. It can also be considered that the fan module 3 can clean the surface to be cleaned more cleanly. However, the greater the power of the fan module 3, the stronger the sound it produces, which will cause serious sound pollution. In addition, increasing the power of the fan module 3 will significantly increase its power consumption, and the battery life of the cleaning equipment will be significantly shortened.

[0091] In the technical solution of the present application, the roller brush assembly 2 is arranged opposite to the dust collection port 12. When the roller brush assembly 2 rotates and sweeps and the fan module 3 generates a negative pressure suction force, part of the garbage (garbage with larger mass) on the surface to be cleaned is swept into the first dust collection chamber 13 by the roller brush assembly 2, and the other part of the garbage (garbage with smaller mass) is sucked into the second dust collection chamber 14. The fan module 3 does not need to operate at full power, and the suction force generated by it only needs to suck part of the garbage with smaller mass into the dust bucket assembly 1. For the part of the garbage with larger mass, since the suction force generated by the fan module 3 cannot suck it into the dust bucket assembly 1, it can be directly swept into the dust bucket assembly 1 by the roller brush assembly 2 rotating and sweeping.

[0092] See also Figures 1 to 3 In the technical solution of the present application, the dust collecting port 12 of the dust bucket assembly 1 is directly arranged opposite to the roller brush assembly 2. When the roller brush assembly 2 rotates for cleaning, the roller brush assembly 2 can sweep large-mass garbage directly into the first dust collecting chamber 13, and the fan module 3 can suck small-mass garbage into the second dust collecting chamber 14. During the cleaning process of the cleaning device, the fan module 3 does not need to run at high power throughout the whole process to clean up all kinds of garbage. The cleaning equipment has high cleaning efficiency, low noise and long battery life.

[0093] In a specific embodiment, when the cleaning device is cleaning, the fan module 3 operates at a low power of 50% of the maximum power. The suction force generated by the fan module 3 can meet the cleaning requirements, and the noise generated by the fan module 3 is also very small, and will not cause serious noise pollution. For those garbage that cannot be directly sucked into the dust bucket assembly 1 by the suction force, the rotating cleaning roller brush assembly 2 can directly sweep this part of the garbage into the first dust collecting chamber 13, so the cooperation between the fan module 3 and the roller brush assembly 2 can clean all the garbage on the surface to be cleaned. Compared with those devices that mainly rely on the suction force generated by the fan module 3 to clean garbage, the cleaning effect brought about by the technical solution of the present application is not bad.

[0094] As the cleaning process continues, the first dust collecting chamber 13 may be filled with garbage. At this time, it is only necessary to increase the power of the fan module 3 briefly. For example, the fan module 3 runs at the maximum power for thirty seconds. The strong suction force generated by the fan module 3 can suck the garbage in the first dust collecting chamber 13 into the second dust collecting chamber 14. During the entire cleaning task of the cleaning device, the fan module 3 runs at a low power state most of the time, which will not affect the cleaning effect, but also effectively reduce the noise level, significantly improving the battery life of the cleaning device.

[0095] See also Figure 1 and Figure 2 In one embodiment of the present application, a dust bucket assembly is provided, and the dust bucket assembly 1 further includes an inclined portion 16, which is arranged at the dust collecting port 12. In the direction from the outside to the inside of the dust collecting port 12, the inclined portion 16 is arranged upwardly from the outside to the inside. It can be understood that the inclined portion 16 forms a slope at the dust collecting port 12, and the top of the inclined portion 16 is higher than the bottom of the barrel body 11. When the garbage enters from the dust collecting port 12, it must first climb over the inclined portion 16 before entering the first dust collecting chamber 13. Since the dust collecting port 12 and the first dust collecting chamber 13 can be roughly considered to be at the same horizontal height, if there is no structure at the dust collecting port 12 to prevent the garbage from leaking out, during the driving of the cleaning equipment or when the dust bucket assembly 1 is tilted, the garbage retained in the first dust collecting chamber 13 is likely to leak out from the dust collecting port 12. Therefore, the inclined portion 16 is equivalent to a structure at the dust collecting port 12 that prevents the garbage from leaking out, and the inclined surface that tilts upward from the outside to the inside does not affect the garbage from entering the first dust collecting chamber 13 from the dust collecting port 12.

[0096] In addition, in order to achieve the same effect, the channel connecting the dust collecting port 12 and the first dust collecting chamber 13 can be designed to be an inclined structure, and the garbage can directly fall into the first dust collecting chamber 13 after climbing over the inclined channel. Alternatively, a structure that blocks the leakage of garbage is provided in the channel connecting the dust collecting port 12 and the first dust collecting chamber 13.

[0097] Further, the first dust collecting chamber 13 is located on one side of the inclined portion 16, and the first dust collecting chamber 13 is connected to the dust collecting port 12. The dust collecting port 12 is located on the cavity wall of the first dust collecting chamber 13, and the dust collecting port 12 is directly connected to the first dust collecting chamber 13. The inclined portion 16 is also located in the first dust collecting chamber 13, and is close to the dust collecting port 12, and the top of the inclined portion 16 is higher than the cavity bottom of the first dust collecting chamber 13.

[0098] In another embodiment of the present application, the dust bucket assembly 1 also includes a dust port channel 17, and the dust port 12 is connected to the first dust collecting chamber 13 through the dust port channel 17. The dust port channel 17 can be set horizontally or tilted upward. The inclined portion 16 is located in the dust port channel 17. The garbage enters the dust port channel 17 through the dust port 12, and then passes through the inclined portion 16 to enter the first dust collecting chamber 13 and stays at the bottom of the first dust collecting chamber 13. In a specific embodiment, the dust port channel 17 is tilted upward, and the angle between the center line of the dust port channel 17 and the ground is α, and the value range of α is [10 degrees to 45 degrees], specifically 30 degrees. In addition, the inclination angle of the dust port channel 17 is the same as the inclination angle of the inclined surface of the inclined portion.

[0099] Further, see Figure 2 The dust bucket assembly 1 further includes a first duct wall 18, which is arranged opposite to the inclined portion 16 to form an upwardly inclined dust collection port channel 17. A portion of the first duct wall 18 is located above the inclined portion 16, and another portion is located above the first dust collection chamber 13. The first duct wall 18 can make the dust collection port channel 17 smoother, and the suction airflow will be smoother when flowing through the inlet channel and the first dust collection chamber 13, which will bring better suction effect. The outer side of the dust collection port channel 17 is the dust collection port 12, and the inner side of the dust collection port channel 17 is connected to the first dust collection chamber 13.

[0100] See also Figure 2 and Figure 3 In one embodiment provided in the present application, the dust bucket assembly 1 also includes a second dust collecting chamber 14. Along the height direction of the barrel body 11, the second dust collecting chamber 14 is located above the first dust collecting chamber 13, and the volume of the second dust collecting chamber 14 is greater than the volume of the first dust collecting chamber 13. The dust collecting channel 15 extends from bottom to top, and the dust collecting channel 15 connects the first dust collecting chamber 13 and the second dust collecting chamber 14 respectively. The garbage collected by the suction airflow and the garbage in the first dust collecting chamber 13 can enter the second dust collecting chamber 14 through the dust collecting channel 15. Arranging the first dust collecting chamber 13 in the lower layer of the dust bucket assembly 1 can make the first dust collecting chamber 13 closer to the roller brush assembly 2, and the garbage cleaned by the roller brush assembly 2 can also enter the first dust collecting chamber 13 more easily.

[0101] See also Figure 2 and Figure 4 The inclined portion 16 can also affect the path of the airflow, thereby facilitating the suction of the garbage in the first dust collecting chamber 13 into the second dust collecting chamber 14. Specifically, when the fan module 3 is running at a low power state, the flow rate of the airflow is relatively low, and the inclined portion 16 does not have a great impact on the airflow. The flow direction of the airflow can be seen in FIG. Figure 2However, when the fan module 3 increases its power, the velocity and flow rate of the airflow will increase, and the inclined portion 16 will affect the airflow direction in the dust collection port channel 17. Figure 4 The direction indicated by the arrow is the direction of the airflow. Due to the presence of the inclined portion 16, the main airflow coming out of the dust collecting port channel 17 can be diverted into a cyclone vortex, which can take away the garbage in the first dust collecting chamber 13, and then the cyclone vortex merges with the main airflow above the first dust collecting chamber 13, so that the garbage in the first dust collecting chamber 13 can be sucked into the second dust collecting chamber 14.

[0102] The cross-sectional shape of the barrel body 11 includes but is not limited to: square, circular, polygonal, etc. Figure 4 , taking the cross-sectional shape of the barrel body 11 as a square as an example. The barrel body 11 includes a front wall 4 and a rear wall 5 arranged opposite to each other, and the dust collecting port 12 is located on the front wall 4. The head end of the dust collecting channel 15 is connected to the top of the first dust collecting chamber 13, and the end of the dust collecting channel 15 is located in the second dust collecting chamber 14. The dust collecting channel 15 can be a pipe connecting the first dust collecting chamber 13 and the second dust collecting chamber 14. The pipe can be round or square.

[0103] In order to effectively improve the utilization rate of the internal space of the dust bucket assembly 1, the dust collection channel 15 is located on the rear wall 5 of the barrel body 11, and the dust collection channel 15 and the rear wall 5 of the barrel body 11 are an integral structure. In one embodiment provided in the present application, the dust bucket assembly 1 also includes a second duct wall 19, and the second duct wall 19 is arranged opposite to the rear wall 5 of the barrel body 11 to form the dust collection channel 15. Using the rear wall 5 of the barrel body 11 as a part of the duct wall of the dust collection channel 15 can effectively combine the dust collection channel 15 with the barrel body 11 structure, thereby improving the space utilization rate inside the dust bucket assembly 1, and can also effectively reduce the area of ​​the sanitary dead corner inside the traditional assembly.

[0104] Furthermore, the dust bucket assembly 1 further includes a movable baffle plate 6, which is disposed at the end of the dust collecting channel 15. When the fan module 3 is not started, the baffle plate 6 can close the end of the dust collecting channel 15, thereby separating the first dust collecting chamber 13 from the second dust collecting chamber 14. This can effectively prevent the garbage or odor in the second dust collecting chamber 14 from flowing back into the first dust collecting chamber 13. When the fan module 3 is started, under the action of the negative pressure suction force, the baffle plate 6 opens, the first dust collecting chamber 13 is connected to the second dust collecting chamber 14 through the dust collecting channel 15, and the garbage in the first dust collecting chamber 13 can enter the second dust collecting chamber 14 through the dust collecting channel 15.

[0105] See also Figure 2In one embodiment provided in the present application, the barrel body 11 is a detachable structure, and the barrel body 11 includes a barrel body 111 and a barrel bottom bracket 112. The barrel body 111 can be connected to the top of the barrel bottom bracket 112, and the dust collection port 12 is located on the barrel bottom bracket 112. Specifically, the barrel body 111 is a square straight cylinder structure, and a slope is provided on the side wall of the barrel bottom bracket 112, and the dust collection port 12 is located on the slope.

[0106] Further, it is convenient to clean the garbage in the dust bucket assembly 1, see Figure 4 and Figure 5 In one embodiment provided in the present application, the barrel bottom support 112 further includes a barrel bottom cover 113, and the barrel bottom cover 113 is detachably connected to the bottom of the barrel bottom support 112. The barrel bottom cover 113 can be considered to be the bottom of the first dust collecting chamber 13. Although the garbage in the first dust collecting chamber 13 can be sucked into the second dust collecting chamber 14 by increasing the power of the fan module 3, it is very likely that there will be garbage with a large mass that cannot be sucked away. Therefore, the detachable barrel bottom cover 113 makes it very convenient for users to clean the first dust collecting chamber 13.

[0107] In the technical solution provided in the present application, the barrel bottom cover 113 is completely detachable, and can also be connected to the barrel bottom support 112 via a rotating shaft 114, see Figure 4 When the first dust collecting chamber 13 needs to be cleaned, the bottom of the first dust collecting chamber 13 can be opened by simply flipping the bottom cover 113 to facilitate cleaning. When the bottom cover 113 is installed at the bottom of the bottom bracket 112, a sealing component is provided between the bottom cover 113 and the bottom bracket 112 to improve the sealing performance of the bottom of the first dust collecting chamber 13.

[0108] See also Figure 6 and Fig. 9 In one embodiment provided in the present application, the dust bucket assembly 1 further includes a bucket cover assembly 7, which is disposed at the upper opening of the bucket body 11. Specifically, the bucket cover assembly 7 is detachably connected to the upper part of the second dust collecting chamber 14 to close the opening above the second dust collecting chamber 14. When the second dust collecting chamber 14 needs to be cleaned, the bucket cover assembly 7 only needs to be directly removed.

[0109] In order to facilitate the connection and disassembly of the bucket cover assembly 7 and the dust bucket assembly 1, the bucket cover assembly 7 is detachably connected to the bucket body 11 through a locking device 8, see Figure 6 and Fig.11The locking device 8 includes a lock body 81 and a lock tongue 82. The lock body 81 is arranged on the barrel cover assembly 7, and the lock tongue 82 is arranged at the end of the lock body 81. The lock tongue 82 can protrude from the edge of the barrel cover assembly 7. A lock groove 83 matching with the lock tongue 82 is arranged on the side wall of the barrel body 11. When the barrel cover assembly 7 is locked and connected with the barrel body 11, the lock tongue 82 is inserted into the lock groove 83. An operating part is arranged on the lock body 81, and the operating part is located at the top of the barrel cover assembly 7. The user can drive the lock body 81 to slide through the operating part to extend or retract the lock tongue 82, and the locking device 8 can be locked or unlocked.

[0110] See also Figure 4 , Figure 6 , Figure 7 and Figure 8 In one embodiment provided in the present application, the barrel cover assembly 7 includes a cover plate 71, an air duct bracket 72 and a filter assembly 73, and the cover plate 71 and the filter assembly 73 are respectively connected to the upper side and the lower side of the air duct bracket 72. Specifically, the cover plate 71 is located on the top surface of the barrel cover assembly 7, and the filter assembly 73 is located on the bottom surface of the barrel cover assembly 7. An installation position is provided on the air duct bracket 72, and the filter assembly 73 is arranged in the installation position. In order to improve the airtightness of the connection between the barrel cover assembly 7 and the barrel body 111, a sealing strip is also provided on the air duct bracket 72.

[0111] The air duct support 72 is provided with an air duct 74, the inlet of the air duct 74 can be considered as the installation position of the filter assembly 73, the filter assembly 73 is arranged at the inlet of the air duct, and the air duct outlet 741 is connected to the fan module 3. Fig.10 , the direction indicated by the arrow is the direction of air flow, when the fan module 3 is running, the air in the second dust collecting chamber 14 can enter the air duct 74 from the air duct entrance after being filtered by the filter assembly 73, and then flow out from the air duct outlet 741. The filter assembly 73 is a filter mesh composed of a multi-material multi-layer structure.

[0112] In a specific embodiment, the inlet of the air duct and the air duct outlet 741 are both located on the bottom surface of the air duct support 72. Of course, the air duct outlet 741 can also be located on the side wall or top surface of the air duct support 72.

[0113] In order to construct a complete air duct 74 on the air duct support 72, an air duct cover plate 742 is further provided on the upper side of the air duct support 72. Fig. 9 As shown, the air duct cover plate 742 is connected to the air duct bracket 72 by fasteners. The setting position of the air duct cover plate 742 is opposite to the air duct outlet 741. When the user needs to clean or maintain the air duct 74, the air duct cover plate 742 can be removed, and then it is very convenient to clean or maintain the air duct 74.

[0114] See also Figure 5In order to facilitate users to install or disassemble the dust bucket assembly 1, the dust bucket assembly 1 also includes a handle 10, which can be rotatably connected to the upper end of the bucket body 111. When the user needs to take out the dust bucket assembly 1, the handle can be directly turned up, and then the operation can be carried out very conveniently.

[0115] Further, see Figure 6 In one embodiment provided in the present application, the barrel body 111 includes a barrel wall portion 121 and a barrel mouth portion 122, the barrel mouth portion 122 is located above the barrel wall portion 121, and the second dust collecting chamber 14 is located in the barrel wall portion 121. The barrel wall portion 121 is a vertebral structure, the cross-sectional area of ​​the upper end of the barrel wall portion 121 is slightly larger than the cross-sectional area of ​​the lower end of the barrel wall portion 121, and the barrel mouth portion 122 is connected to the upper end of the barrel wall portion 121. The cross-sectional area of ​​the barrel mouth portion 122 is larger than the cross-sectional area of ​​the barrel wall portion 121, and the barrel cover assembly 7 is connected to the barrel mouth portion 122. Viewed along the height direction of the barrel body 111, the barrel mouth portion 122 is the large end of the barrel body 111. When the barrel cover assembly 7 is connected to the barrel mouth portion 122, the filter assembly 73 on the barrel cover assembly 7 is arranged opposite to the upper end of the barrel wall portion 121, and the area of ​​the filter assembly 73 is roughly equal to the cross-sectional area of ​​the upper end of the barrel wall portion 121. By providing a barrel mouth portion 122 with a larger area above the barrel wall portion 121 , a filter assembly 73 with a larger area can be installed on the dust barrel assembly 1 , while also leaving more space for the air duct on the air duct bracket 72 .

[0116] In another embodiment, the cross-sectional area of ​​the barrel mouth 122 may also be approximately equal to the cross-sectional area of ​​the barrel wall 121 , the barrel body 111 is a square structure, and the barrel cover assembly 7 is disposed in the barrel mouth 122 at the upper end of the barrel body 111 .

[0117] See also Figure 6 In one embodiment provided in the present application, along the width direction of the dust bucket assembly 1, Figure 6 In the direction of the middle arrow X, the width of the barrel bottom bracket 112 is smaller than the width of the barrel body 111. Ignoring the wall thickness of the barrel bottom bracket 112, the length of the dust collecting port 12 is approximately equal to the width of the barrel bottom bracket 112. At the middle position of the dust collecting port 12, the dust collecting port 12 is also provided with a notch, so that the area of ​​the middle region of the dust collecting port 12 is larger.

[0118] When cleaning equipment performs cleaning operations in shopping malls, hotels, office buildings and other areas, it needs to face complex working environments. It not only needs to be able to effectively avoid obstacles in the working area, but also be able to deal with pedestrians walking around at will. Cleaning equipment usually performs cleaning operations in an autonomous manner, so cleaning robots must have certain environmental perception and obstacle avoidance capabilities.

[0119] In one embodiment provided in the present application, a plurality of detection sensors are provided on the device body 100 of the cleaning robot. The detection sensors may be provided on the housing 102, or on the front bracket 103 and the rear bracket 104. For example, some sensors are provided on the front bracket 103 and the rear bracket 104. Figures 13 to 19 The cleaning robot includes a forward sensor 51 and a backward sensor 52. The forward sensor 51 is arranged on the front bracket 103, and the backward sensor 52 is arranged on the rear bracket 104. The forward sensor is used to detect obstacles and pedestrians in front of the cleaning device. The forward sensor 51 can also identify the cleaning area in front of the cleaning device, so as to facilitate the cleaning device to plan the travel path. The backward sensor 52 is used to detect obstacles behind the cleaning device, so as to facilitate the cleaning device to avoid obstacles when reversing.

[0120] See also Fig.18 , the forward sensor 51 includes a first sensor 511 and a second sensor 512, the first sensor 511 and the second sensor 512 are arranged up and down along the height direction of the front bracket 103, the first sensor 511 can be used to identify obstacles and pedestrians, and the second sensor 512 can be used to identify the edge of the cleaning area, thereby generating a topographic map of the cleaning area to assist the cleaning device in path planning. In a specific example, the first sensor 511 includes an RGB-D sensor 5111 (depth sensor) tilted upward, and an RGB-D sensor 5112 tilted downward, and the two depth sensors are used to detect the depth information in front of the cleaning device. The detection range of the RGB-D sensor 5111 tilted upward is the area horizontally facing upward in front of the cleaning device, for example, it can detect walking pedestrians and obstacles above the cleaning device. The detection range of the RGB-D sensor 5112 tilted downward is the area horizontally facing downward in front of the cleaning device, for example, it can detect low obstacles on the ground, pets such as puppies, etc. The two depth sensors can not only detect objects in different areas independently, but also cooperate with each other to detect pedestrians in front of the cleaning equipment, thereby reducing the occurrence of misjudgment.

[0121] The second sensor 512 is located below the first sensor 511. The second sensor 512 can be a DTOF (Direct Time-of-Flight) sensor, which can be considered as a line laser sensor. It can not only detect obstacles in front of the cleaning equipment, but also map the area to be cleaned, thereby generating a topographic map of the area to be cleaned, thereby improving the accuracy of the cleaning equipment's travel path.

[0122] The rearward sensor 52 includes a third sensor 521, which can also be an RGB-D sensor to collect depth information behind the cleaning device. It can not only detect whether there are pedestrians approaching behind the cleaning device, but also be used to avoid obstacles when the cleaning device is reversing.

[0123] See also Fig.13 and Fig.14 In order to improve the intelligence level and safety of the cleaning device, the cleaning device is further provided with a plurality of fourth sensors 522 on the body. Specifically, Fig.13 As shown in , a fourth sensor 522 is respectively provided on the left and right sides of the front end of the front shell 132 of the cleaning robot, and a fourth sensor 522 is respectively provided on the left and right sides of the shell body 131, that is, on the left and right sides of the device body 100, which can detect the range of the left and right sides of the device body 100, thereby reducing the detection blind area of ​​the cleaning device. The fourth sensor 522 can be an ultrasonic sensor or an infrared sensor. In order to facilitate the sensors on the front bracket 103 and the rear bracket 104 to detect the environment outside the shell 102, the shell 102 is provided with windows corresponding to the locations where the sensors are set.

[0124] In order to further improve the safety of the cleaning device and give more prompts to pedestrians when the cleaning device is running, indicator lights 550 are provided at the corners around the cleaning device housing 102. When the cleaning device is working, the indicator lights 550 flash to prompt pedestrians to pay attention.

[0125] See also Fig.13 and Fig. 20 As mentioned above, in order to provide the last layer of protection for the cleaning equipment, a collision plate shell 136 is provided at the front end of the chassis 101. When the collision plate shell 136 collides with an obstacle, the collision detection sensor can be triggered, and the cleaning equipment can control the cleaning equipment to stop in time according to the collision detection signal. Since the bottom surface of the collision plate shell 136 faces the ground, an anti-fall detection sensor 53 and a carpet detection sensor 54 are provided on the collision plate shell 136. The anti-fall detection sensor 53 can detect the height change of the ground in front of the cleaning equipment. When it is detected that the height change of the ground in front of the cleaning equipment suddenly increases, the cleaning equipment can stop in time according to the detection signal. The carpet detection sensor 54 can detect whether there is a carpet under the collision plate shell 136, and the cleaning equipment can switch to the carpet cleaning mode according to the detection signal.

[0126] In the above, the detection of whether the collision occurs on the collision plate shell 136 is mainly to detect whether the sensor between the collision plate shell 136 and the chassis 101 is triggered after the collision plate shell 136 is displaced. In another embodiment, the collision plate shell 136 can also be fixedly connected to the chassis 101 or the shell body 131, and an air pressure sensor is distributed on the outer surface of the collision plate shell 136. When the collision occurs on the collision plate shell 136, the air pressure sensor will be triggered. It can be understood that a circle of airbags is provided on the periphery of the collision plate shell 136. When the airbag is hit, the air pressure inside it increases, thereby triggering the air pressure sensor.

[0127] like Fig.15 As shown, the fan module 3 is arranged between the dust bucket assembly 1 and the rear bracket 104, so that the free space in the device body 100 can be fully utilized. In addition, the power battery 43 and the fan module 3 are arranged on the front and rear sides of the dust bucket assembly 1, which is conducive to the uniform weight distribution of the entire cleaning device and the center of gravity of the cleaning device is more stable. The fan module 3 is mainly used to draw negative pressure to the dust bucket assembly 1, so that a suction airflow can be formed at the dust collection port to suck the garbage into the dust bucket assembly 1. Fig.21 The air inlet of the fan module 3 is connected to the interface of the dust bucket assembly 1 through the fan duct, and the air outlet of the fan module 3 is provided with a filter 32. The airflow can be discharged through the exhaust port 33 after being filtered by the filter 32. In order to further eliminate the noise generated by the fan module 3, the outer periphery of the fan module 3 is wrapped with a sound-absorbing sponge 34.

[0128] See also Fig.14 , Fig.16 and Fig. 22 The cleaning device also includes a charging module 61, which is used to charge the power battery 43 on the cleaning device. The charging module 61 is arranged on the rear bracket 104, and the charging module 61 is located below the rear sensor 52. In order to facilitate the docking and charging of the cleaning device with the charging pile 200, the charging end 611 of the charging module 61 is arranged on the shell 102 on the rear side of the device body 100 of the cleaning device, that is, a charging port is opened on the rear shell 133, and the charging electrode of the charging module 61 is arranged in the charging port. When the cleaning device is docked with the charging pile 200, the charging electrode will be connected to the charging end 611 on the charging pile 200 to provide charging current for the charging module 61.

[0129] Although the cleaning device can clean most of the surface to be cleaned in an autonomous manner, there may still be local dirt on the surface to be cleaned or areas that the cleaning device cannot clean autonomously. In this case, manual intervention is required, that is, the cleaning device cleans the areas that cannot be cleaned under manual control.

[0130] In order to facilitate the user to operate the cleaning device, the cleaning device still has a handle 62, which is arranged on the rear bracket 104. When the cleaning device is switched to the manual control mode, the user can control the cleaning device to move through the handle 62 to clean the local dirty area or the area that cannot be cleaned autonomously. In order to improve the convenience of operation, the handle 62 is connected to the rear bracket 104 through a telescopic rod 63. After the handle 62 is pulled out, the telescopic rod 63 will connect the handle 62 to the rear of the device body 100 in an inclined state.

[0131] Carpets are also laid on the ground in shopping malls, hotels, office buildings and other areas. When the cleaning device is cleaning the carpeted floor, the mopping component 9 on the cleaning device can easily wet the carpet, causing secondary pollution. Fig.16 , Fig.24 and Fig.25 For example, the mop member 91 on the mop assembly 9 is a rag plate, and the rag plate is arranged on the rear side of the chassis 101 through the lifting module 92. The mop member 91 is connected to the chassis 101 in a floating manner through the lifting module 92, and the lifting module 92 can drive the mop member 91 to move up and down in the vertical direction. When the cleaning device recognizes that a carpet is laid on the ground in front, the lifting module 92 drives the mop member 91 to lift before the cleaning device steps on the carpet. After the cleaning device steps on the carpet, the mop member 91 does not contact the carpet, thereby avoiding soiling the carpet.

[0132] Furthermore, the lifting module 92 includes a power unit 921, a lifting bracket 922 and a lifting arm 923. The lifting bracket 922 can be arranged on the base. One end of the lifting arm 923 is connected to the lifting bracket 922, and the other end is connected to the mopping and washing part 91. The power unit 921 is connected to the lifting arm 923. The power output of the power unit 921 can drive the lifting arm 923 to extend and retract, thereby driving the mopping and washing part 91 to move up and down. The connection between the power unit 921 and the lifting arm 923 is not fixedly connected. The mopping and washing part 91 can be connected to the lifting bracket 922 in a floating manner through the lifting module 92. When there is a raised obstacle on the ground, the mopping and washing part 91 can automatically float up after contacting the obstacle, thereby preventing the mopping and washing part 91 from being damaged by a large impact.

[0133] As mentioned above, the top shell 134 is provided with a top cover 135, and the top cover 135 can be opened to facilitate the disassembly and assembly of the dust bucket assembly 1. Fig.26 and Fig. 27 In one embodiment provided in the present application, the top cover 135 can be flipped and connected to the top shell 134, and opening the top cover 135 is convenient for the user to extract the dust bucket assembly 1. In addition, a plurality of operation buttons are provided on the top shell 134, such as a power button, an emergency stop switch, a mode adjustment switch, and a key switch. The plurality of operation buttons are provided on the top shell 134, so that the user can operate the buttons conveniently.

[0134] As mentioned above, the ground environment in shopping malls, hotels, office buildings and other areas is complex. After a long period of cleaning, the roller brush assembly 2 and the side brush assembly 25 are prone to hair and garbage entanglement. If the entangled hair and garbage are not cleaned up in time, the cleaning power of the roller brush assembly 2 and the roller brush assembly 2 will be seriously affected. In addition, if the roller brush assembly 2 and the roller brush assembly 2 are frequently cleaned manually, it is necessary to frequently stop the machine for cleaning, which is not only time-consuming and labor-intensive, but also has a low cleaning efficiency.

[0135] See also Figure 1 , Fig.13 , Fig.28 and Fig.29 In order to solve the above problems, a cleaning device is also provided in one embodiment of the present application. The cleaning device includes: a chassis 101, a roller brush assembly 2, a roller brush assembly 2, a first anti-winding member 28 and a second anti-winding member 29. The roller brush assembly 2 includes a roller brush cavity shell 26 and a cleaning roller brush 27. The roller brush cavity shell 26 is connected to the chassis 101. The cleaning roller brush 27 is arranged in the roller brush cavity shell 26. The roller brush cavity shell 26 has a roller brush opening with an opening facing downward. The roller brush bristles on the cleaning roller brush 27 can clean the ground through the roller brush opening. The side brush assembly 25 is arranged at a corner of the front end of the chassis 101, and part of the side brush bristles of the side brush assembly 25 extends out of the chassis 101. The first anti-winding member 28 is arranged at the roller brush opening along the length direction of the cleaning roller brush 27. The first anti-winding member 28 is provided with a plurality of comb tooth structures to comb out the windings on the roller brush bristles. The second anti-winding member 29 is arranged on the chassis 101 and is located on the rotation path of the side brush bristles to comb out the windings on the side brush bristles.

[0136] See also Fig.28 and Fig.29 , along the length direction of the chassis 101, the side brush assembly 25 is located obliquely in front of the roller brush assembly 2, and the distance between the side brush assembly 25 and the roller brush opening is less than the radius of the side brush assembly 25. It can be understood that the cleaning area of ​​the side brush assembly 25 and the cleaning area of ​​the roller brush assembly 2 partially overlap, so that the side brush assembly 25 can more easily clean the external garbage into the cleaning range of the roller brush assembly 2, thereby facilitating the roller assembly to collect the garbage cleaned by the roller brush assembly 2.

[0137] Since the side brush assembly 25 partially overlaps with the cleaning area of ​​the roller brush assembly 2, the side brush bristles on the side brush assembly 25 are easily rolled into the roller brush assembly 2. In an embodiment provided in the present application, the second anti-winding member 29 is located in front of the roller brush opening and close to the end of the roller brush opening. As the roller brush assembly 2 rotates, the second anti-winding member 29 can not only comb the side brush bristles in sequence, but also play a blocking role on the side brush bristles, preventing the side brush bristles from directly contacting the roller brush bristles on the cleaning roller, causing the side brush bristles to be rolled into the roller brush assembly 2.

[0138] Furthermore, the second anti-winding member 29 has a vertical section and a folded edge section, the vertical section extends downward from the bottom surface of the chassis 101, the folded edge section is obliquely arranged at the end of the vertical section, and the extension direction of the folded edge section is opposite to the rotation direction of the side brush assembly 25. The vertical section and the folded edge section form an L-shaped structure, which can not only better comb the side brush bristles, but also prevent the side brush bristles from detaching from the second anti-winding member 29 during the combing process of the side brush bristles.

[0139] See also Figure 30 to Figure 35 In one embodiment of the present application, a roller brush assembly 2 is further provided, the roller brush assembly 2 comprising a bottom plate 231, a roller brush cavity shell 26, a connecting rod assembly 232 and a lifting device. A cleaning roller brush 27 is disposed in the roller brush cavity shell 26, the roller brush cavity shell 26 having a roller brush opening opening facing downward, and the roller brush bristles on the cleaning roller brush 27 can clean the floor through the roller brush opening. The roller brush assembly 2 also comprises a roller brush motor 271, the roller brush motor 271 is disposed in the roller brush cavity shell 26, and the roller brush motor 271 is transmission-connected to the cleaning roller brush 27.

[0140] One end of the connecting rod assembly 232 is connected to the bottom plate 231, and the other end is connected to the roller brush chamber housing 26. The roller brush chamber housing 26 is connected to the bottom plate 231 in a floating manner through the connecting rod assembly 232. The bottom plate 231 can be connected to the chassis 101 of the cleaning device mentioned above, and the bottom plate 231 can also be considered as a part of the chassis 101. The lifting device includes a power assembly 236 and a driving rod. The power assembly 236 is arranged on the bottom plate 231, one end of the driving rod is connected to the roller brush chamber housing 26, and the other end of the driving rod is connected to the power assembly 236. The power assembly 236 can drive the roller brush chamber housing 26 to move up and down through the driving rod.

[0141] The floating connection shell between the roller brush chamber shell 26 and the bottom plate 231 is understood to be that the roller brush chamber shell 26 and the bottom plate 231 are in a state of active connection, and the roller brush assembly 2 is in contact with the ground under the action of gravity or elastic force. When the cleaning roller brush 27 is subjected to a large upward force, the cleaning roller brush 27 can automatically float upward, thereby avoiding the cleaning roller brush 27 from being damaged by a large impact force.

[0142] For example, when there are obstacles such as troughs and thresholds on the ground, when the cleaning device passes over the obstacle, the cleaning roller brush 27 at the bottom will directly contact the obstacle. In the technical solution provided in the present application, if the impact force on the cleaning roller brush 27 is too large, the roller brush cavity shell 26 connected to the cleaning roller brush 27 will float upward at the same time, which can avoid a more intense collision between the cleaning roller brush 27 and the obstacle. The floating connection between the roller brush cavity shell 26 and the bottom plate 231 is similar to the floating connection between the mopping assembly 9 and the chassis 101, both of which can avoid excessive impact when encountering raised obstacles on the ground.

[0143] like Fig.31 and Fig.32 As shown, the connecting rod assembly 232 includes a first connecting plate 233 and a plurality of parallel connecting rods, and the first connecting plate 233 is vertically downwardly arranged on the bottom surface of the base plate 231. The roller brush chamber shell 26 is located on one side of the first connecting plate 233, and the plurality of parallel connecting rods are respectively hinged to the first connecting plate 233 and the roller brush chamber shell 26. Taking the connecting rod assembly 232 as an example including two parallel connecting rods, one end of the connecting rod is hinged to the first connecting plate 233, and the other end is hinged to the roller brush chamber shell 26. When the roller brush chamber shell 26 is raised or lowered, the connecting rod will rotate and swing with it. A hinge plate 234 is also provided on the roller brush chamber shell 26, and the connection between the connecting rod and the roller brush chamber shell 26 through the hinge plate 234 is more stable.

[0144] Furthermore, a second connecting plate 235 is also provided on the bottom plate 231, and the driving rod is rotatably connected to the second connecting plate 235. One side of the rotating point 2375 on the driving rod is a power arm 2371, and the other side is a resistance arm 2372. The output end of the power assembly 236 abuts against the power arm 2371, and the end of the resistance arm 2372 is hinged to the roller brush chamber shell 26. The power arm 2371 and the resistance arm 2372 are vertically arranged, and the end of the resistance arm 2372 is provided with a slide groove, and the connecting piece on the roller brush chamber shell 26 is connected to the slide groove. Specifically, the power assembly 236 includes but is not limited to: a linear motor, a cylinder, a hydraulic cylinder, etc. See. Fig.31 As shown, when the power assembly 236 pushes the power arm 2371 to move in the direction of the arrow X in the figure, the end of the resistance arm 2372 will move in the direction of the arrow Y in the figure, thereby driving the roller brush chamber housing 26 to lift upward through the connecting piece. When the output end of the power assembly 236 retracts, due to the absence of resistance, the roller brush chamber housing 26 will automatically move downward under the action of gravity, and at the same time, the end of the resistance arm 2372 will move in the opposite direction of the arrow Y, the driving rod rotates around the rotation point 2375, and the end of the power arm 2371 moves in the opposite direction of the arrow X and always abuts against the output end of the power assembly 236.

[0145] In addition, to facilitate users to perform in-depth maintenance on the roller brush, see Fig.33 , the cleaning roller brush 27 can be disassembled from the roller brush chamber shell 26, and then the user can perform deep cleaning on the cleaning roller brush 27 alone. Specifically, one end of the roller brush chamber shell 26 has a disassembly port, and the cleaning roller brush 27 can be installed and disassembled through the disassembly port.

[0146] The cleaning device provided by the present application is described in detail below through another specific embodiment.

The roller brush assembly 2 is arranged in the roller brush cavity 21, and the dust collecting port 12 is connected to the roller brush cavity 21, so that the negative pressure suction force generated by the fan module 3 can be more concentrated around the roller brush assembly 2, thereby facilitating the suction of garbage around the roller brush assembly 2.

[0148] Further, see Fig.12 A guide assembly 22 is provided between the roller brush chamber 21 and the dust collecting port 12. The guide assembly 22 has a guide channel 23. The guide channel 23 is in communication with the roller brush chamber 21. The end of the guide assembly 22 has a docking fastener 220. Specifically, the inlet of the guide channel 23 is connected to the roller brush chamber 21, the outlet of the guide channel 23 is docked with the dust collecting port 12, and the docking fastener 220 is connected to the dust collecting port 12. The docking fastener 220 can be a rubber-coated fastener, the surface of which is coated with rubber, silicone, sealant, etc. When the docking fastener 220 is connected to the dust collecting port 12, the colloid can make the docking fastener 220 and the dust collecting port 12 more tightly connected. The guide channel 23 can not only make the dust collecting port 12 and the roller brush chamber 21 more tightly connected, but also construct a smoother airflow path.

[0149] In addition, when the length of the dust collection port 12 is less than the length of the roller brush assembly 2, the guide assembly 22 can also play the role of transition connection. For example, the guide assembly 22 is trumpet-shaped, the length of the inlet of the guide channel 23 is adapted to the length of the roller brush assembly 2, and the length of the outlet of the guide channel 23 is adapted to the length of the dust collection port 12, thereby playing the role of transition connection.

[0150] See also Figures 1 to 3 In one embodiment provided in the present application, the cleaning device can not only clean and vacuum the floor, but also wet clean the floor.

When the cleaning device is cleaning, the roller brush assembly 2 and the fan module 3 first clean and vacuum the floor, and then the mop assembly 9 at the rear wet-cleans the floor.

[0151] The mop cleaning member 91 may be a mop cloth fixed to the mop cleaning assembly 9, or a rotatable mop plate provided on the mop cleaning assembly 9. In order to facilitate the cleaning device to clean both ordinary floors and floors such as carpets, a lifting module 92 is provided on the mop cleaning assembly 9. When the cleaning device cleans the ordinary floor, the lifting module 92 drives the mop cleaning assembly 9 to descend, and the mop cleaning member 91 can mop the floor.

[0152] The technical solution provided by this application is further described in detail below in combination with specific application scenarios.

[0153] Application scenario 1

[0154] A commercial cleaning equipment used in shopping mall environments. Due to the complex personnel and numerous commodities in the shopping mall. Various kinds of garbage are also easily generated on the ground of the shopping mall. If all kinds of garbage are cleaned up by the negative pressure suction force generated by the fan module alone, it is necessary for the fan module to generate a strong negative pressure suction force. However, the huge noise generated by the fan module will inevitably affect the guests in the mall and reduce the shopping experience of the guests. To avoid this situation, the fan module can be operated in a low-power state, and the fan module works in conjunction with the roller brush assembly. Larger garbage can be directly swept into the dust collection port by the roller brush assembly and temporarily stored in the first dust collection chamber; while smaller garbage can be sucked into the second dust collection chamber by the low-power fan module, thereby achieving the goal of cleaning up all kinds of garbage.

[0155] Application scenario 2

[0156] The commercial cleaning equipment collects heavier garbage in the first dust collection chamber through the roller brush assembly, and the fan module collects lighter garbage in the second dust collection chamber. When the first dust collection chamber is full, or when the commercial cleaning equipment is running in an open area with few people, the low-power fan module can be temporarily switched to a high-power state, thereby sucking the garbage in the first dust collection chamber into the second dust collection chamber. The commercial cleaning equipment can then go to the area with dense population and more garbage to clean again.

[0157] To sum up, in the technical solution of the present application, the dust collecting port of the dust bucket assembly is directly arranged opposite to the roller brush assembly. When the roller brush assembly rotates to clean, the roller brush assembly can sweep large-mass garbage directly into the first dust collecting chamber, and the fan module can suck smaller-mass garbage into the second dust collecting chamber. During the cleaning process of the cleaning equipment, the fan module does not need to run at high power throughout the whole process to clean up all kinds of garbage. The cleaning equipment has high cleaning efficiency, low noise, and long battery life.

[0158] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present application, rather than to limit it. Although the present application has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein. However, these modifications or replacements do not deviate the essence of the corresponding technical solutions from the spirit and scope of the technical solutions of the embodiments of the present application.
