Description

[Technical Field]

[0001] This invention relates to the field of intelligent robot technology, and in particular to an intelligent household sweeping robot. [Background Technology]

[0002] A robotic vacuum cleaner, also known as an automatic cleaning machine, smart vacuum cleaner, or robotic vacuum cleaner, is a type of smart home appliance that uses artificial intelligence to automatically clean floors in a room. Robotic vacuum cleaners typically use a combination of brushing and vacuuming to suck up debris from the floor and collect it in their own dustbin, thus completing the floor cleaning function.

[0003] Existing robotic vacuum cleaners tend to sweep up trash or dust during cleaning, preventing the dirt from being properly vacuumed into the robot. This results in low cleaning efficiency and the stirring up of dust, which is detrimental to the indoor environment and leads to a poor user experience. [Summary of the Invention]

Individual replacement of the second antennae assembly allows for partial bristle replacement, saving materials and costs. The circular base plate rotates the wiping cloth, improving wiping effectiveness and resulting in a cleaner floor. The wiping plate presses the wiping cloth down, increasing friction and further enhancing the wiping effect, leading to a cleaner floor. [Attached Image Description]

Detailed Implementation Methods

[0026] To make the objectives, technical solutions, and advantages of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are for illustrative purposes only and are not intended to limit the invention.

[0028] Furthermore, in this invention, descriptions involving "first," "second," etc., are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined as "first" or "second" may explicitly or implicitly include at least one of that feature. In the description of this invention, "a plurality of" means at least two, such as two, three, etc., unless otherwise explicitly specified.

[0029] Please see Figures 1 to 10 The intelligent household sweeping robot of the present invention includes a robot body 100 and a robot base station 200. A robot placement slot 210 is provided on one side of the bottom of the robot base station 200. A ramp 220 is provided on the outer side of the robot placement slot 210. The ramp 220 facilitates the robot body 100 to enter and exit the robot placement slot 210.

[0030] The robot body 100 can be wirelessly charged within the robot placement slot 210. During operation, the robot body 100 moves out of the robot placement slot 210 to clean the indoor floor. After cleaning, it re-enters the robot placement slot 210 to recharge, and waits for the next operation once fully charged. The technology by which the robot base station 200 charges the robot body 100 can be achieved using existing robotic vacuum cleaner technology, and will not be elaborated here.

[0031] Two brushing components 110 are located at the bottom front of the robot body 100. Each brushing component 110 is equipped with bristles 113. The rotation of the brushing component 110 drives the bristles 113 to clean the ground. The brushing component 110 on the left rotates clockwise, and the brushing component 110 on the right rotates counterclockwise. The two brushing components 110 rotate towards each other, which can gather dirt towards the bottom of the robot body 100 for cleaning as much as possible, reduce the occurrence of sweeping garbage, and improve cleaning efficiency.

[0032] The robot body 100 has a suction port 120 at its bottom. Inside the robot body 100 are a collection box and a suction device. The suction port 120 is connected to the collection box, which is in turn connected to the suction device. The suction device provides vacuum suction to draw dirt from the suction port 120 into the collection box for temporary storage. A filter screen is installed between the suction device and the collection box to filter dirt and prevent it from entering the suction device. The suction port 120 is located at the rear center of the two brushing components 110. The two brushing components 110 sweep dirt towards the center, which is precisely in the path of the suction port 120, facilitating more efficient dirt intake. A rotating roller brush is installed inside the suction port 120. The rotation of the roller brush allows for further cleaning of the area after dirt has been sucked in, resulting in a more thorough cleaning.

[0033] The brushing assembly 110 includes a brush connector 111, on which multiple brush tips 112 are connected. Each brush tip 112 has multiple vacuum suction holes 1123, which are connected to a collection box and an adsorption device. Under the vacuum adsorption of the adsorption device, a negative pressure adsorption effect is formed around each brush tip 112. When the brushing assembly 110 rotates to clean, the negative pressure adsorption effect around the brush tips 112 causes dust and small particles of dirt to gather near the brush tips 112, preventing dust from rising and polluting the environment during cleaning, improving cleaning efficiency, avoiding dust flying everywhere during cleaning, and improving the user experience. Brush bristles 113 are fixed on the brush tips 112.

[0034] The brushing assembly 110 includes a first hollow shaft 114, with a brush connector 111 threadedly connected to one end of the first hollow shaft 114. The brush antenna 112 is hollow internally, and a vacuum adsorption hole 1123 is connected to the brush connector 111, which in turn is connected to the first hollow shaft 114. A first rotary joint 116 is connected to one end of the first hollow shaft 114, and a flexible air tube is connected externally to the first rotary joint 116. This flexible air tube connects to the collection box and the adsorption device. When the adsorption device generates a vacuum adsorption force, a vacuum adsorption effect is simultaneously generated within the first hollow shaft 114, the brush connector 111, and the brush antenna 112 via the flexible air tube. Finally, external dust and small particles of dirt are adsorbed through the vacuum adsorption hole 1123. Because the bristles 113 on the brushing antennae 112 easily become dirty after each cleaning, continued use would compromise the cleaning effect. Therefore, the brushing connector 111 and the first hollow shaft 114 are connected by a thread, making disassembly and assembly convenient. This allows the brushing connector 111 to be removed for cleaning of the bristles 113, and then reassembled back into the robot body 100 after the bristles 113 are clean, ensuring the bristles 113 are clean for the next cleaning and guaranteeing a cleanliness effect each time. The connection end between the brushing connector 111 and the first hollow shaft 114 is provided with a negative pressure chamber. The inner side of the negative pressure chamber is provided with an internal thread, and the end of the first hollow shaft 114 is provided with an external thread that matches the internal thread. The negative pressure chamber is connected to the interior of the brushing antennae 112.

[0035] A first synchronous wheel 115 is fixed to the outside of the first hollow shaft 114. A first drive motor 118 is installed inside the robot body 100. The output end of the first drive motor 118 is connected to a second synchronous wheel 117. The second synchronous wheel 117 and the first synchronous wheel 115 are at the same height and are connected to each other by a first synchronous belt 119. The first drive motor 118 drives the second synchronous wheel 117 to rotate, and the second synchronous wheel 117 drives the first synchronous wheel 115 to rotate via the first synchronous belt 119. The first synchronous wheel 115 drives the first hollow shaft 114 to rotate, and the first hollow shaft 114 drives the brush connector 111 to rotate. The brush connector 111 drives the brush antenna 112 to rotate and clean.

[0036] The first hollow shaft 114, the first synchronous pulley 115, the first rotary joint 116, and the flexible air tube are all located inside the robot body 100. The brush connector 111 and the brush antenna 112 are located outside the robot body 100 for easy disassembly and cleaning.

[0037] The brushing antenna 112 includes a first antenna assembly 1121 and a second antenna assembly 1122. The first assembly 1121 is integrally formed on the brushing connector 111, and the second antenna assembly 1122 is snapped and fixed to the first antenna assembly 1121. The bristles 113 are fixed on the second antenna assembly 1122. After prolonged use, the bristles 113 on the second antenna assembly 1122 will inevitably fall off. When most of the bristles 113 on the same brushing connector 111 have fallen off, replacing the entire brushing connector 111 is the best option. However, if only some of the bristles 113 on the second antenna assembly 1122 have fallen off significantly, while the bristles 113 on other second antenna assembly 1122 are still relatively intact, replacing the entire brushing connector 111 would be wasteful. Therefore, the present invention uses the snap-fit ​​method between the second antenna assembly 1122 and the first antenna assembly 1121, which makes disassembly and assembly convenient. The effect of replacing the bristles 113 can be achieved by replacing the second antenna assembly 1122 alone, thus saving materials and costs.

[0038] One end of the second antennal assembly 1122 is provided with a snap-fit ​​groove 1124, and the inner sides of the snap-fit ​​groove 1124 are provided with inlay flanges 1125. One end of the first antennal assembly 1121 is provided with a snap-fit ​​block 1127 that matches the snap-fit ​​groove 1124. The snap-fit ​​block 1127 is provided with an inlay groove 1128 that matches the inlay flange 1125. The snap-fit ​​block 1127 snaps into the snap-fit ​​groove 1124, and the inlay flange 1125 snaps into the inlay groove 1128, thereby achieving snap-fit ​​fixation between the second antennal assembly 1122 and the first antennal assembly 1121. The interiors of the second antennal assembly 1122 and the first antennal assembly 1121 are hollow. Vacuum suction holes 1123 are opened on the side and bottom surface of the first antennal assembly 1121. The bottom surface of the second antenna assembly 1122 is provided with a bristle fixing hole 1126, and the bristles 113 are fixed on the bristle fixing hole 1126.

[0039] The robot body 100 is provided with a wiping component 130 at its bottom. The wiping component 130 is located behind the suction port 120. The wiping component 130 is used to wipe the floor after sweeping to achieve the effect of mopping and further improve the cleaning effect.

[0040] Two germicidal lamps 160 are provided at the bottom of the robot body 100. The two germicidal lamps 160 are located on the rear sides of the wiping assembly 130, respectively. The germicidal lamps 160 are used for ultraviolet irradiation sterilization to further improve the cleaning effect.

[0041] A directional control wheel 140 is provided at the front bottom of the robot body 100, and two power wheels 150 are provided at the rear bottom of the robot body 100. The directional control wheel 140 is used to control the direction of travel of the robot body 100, and the power wheels 150 provide power.

[0042] A scanning device 170 is provided at the top front of the robot body 100. The scanning device 170 is used to scan for obstacles, which helps the robot body 100 avoid obstacles during cleaning and prevents collisions. A start button 180 is provided at the top rear of the robot body 100.

[0043] The robot body 100 has a control circuit board inside. The start button 180, scanning device 170, brushing assembly 110, adsorption device, wiping assembly 130, direction control wheel 140, power wheel 150, and germicidal lamp 160 are all connected to the control circuit board and are controlled by the control circuit board in a coordinated manner. The circuit design of the control circuit board can be achieved by existing technology and will not be described in detail here.

[0044] The wiping assembly 130 includes a circular base plate 131, a wiping plate 137 is disposed on the outer side of the circular base plate 131, and a wiping cloth is fixed on the outer side of the wiping plate 137, the wiping cloth wiping the ground.

[0045] A second hollow shaft 132 is vertically fixed at the center of the inner side of the circular base plate 131. A third synchronous wheel 133 is fixed to the outer side of the second hollow shaft 132. A second drive motor 135 is installed inside the robot body 100. The output end of the second drive motor 135 is connected to a fourth synchronous wheel 134. The outer sides of the fourth synchronous wheel 134 and the third synchronous wheel 133 are connected by a second synchronous belt 136. The second drive motor 135 drives the fourth synchronous wheel 134 to rotate. The fourth synchronous wheel 134 drives the third synchronous wheel 133 through the second synchronous belt 136. The third synchronous wheel 133 drives the second hollow shaft 132 to rotate. The second hollow shaft 132 drives the circular base plate 131 to rotate. The circular base plate 131 drives the wiping cloth to rotate and wipe, which helps to improve the wiping effect and make the floor cleaner.

[0046] The inner side of the wiping plate 137 is vertically connected with several guide posts 1371. One end of each guide post 1371 passes through the circular substrate 131. A limiting plate 1372 is provided at the end of the guide post 1371 that passes through the circular substrate 131. The limiting plate 1372 is used to prevent the guide post 1371 from coming off the circular substrate 131. The guide post 1371 connects the wiping plate 137 and the circular substrate 131 into one unit. In this way, the rotation of the circular substrate 131 can drive the wiping plate 137 to rotate, and the rotation of the wiping plate 137 can drive the wiping cloth to rotate and wipe.

[0047] A third hollow shaft 138 is disposed inside the second hollow shaft 132. One end of the third hollow shaft 138 is connected to the inner side of the wiping plate 137. A bearing is provided at the connection between the third hollow shaft 138 and the wiping plate 137, so that the rotation of the wiping plate 137 does not drive the third hollow shaft 138 to rotate. The other end of the third hollow shaft 138 is fixedly connected to a lifting plate 139, and a lifting cylinder 1391 is connected to the lifting plate 139. The lifting cylinder 1391 drives the lifting plate 139 to press down, the lifting plate 139 drives the third hollow shaft 138 to press down, the third hollow shaft 138 drives the wiping plate 137 to press down, and the wiping plate 137 drives the wiping cloth to press down. This pressing action is used to increase the wiping friction, further improve the wiping effect, and facilitate a cleaner floor.

[0048] The guide post 1371 is fitted with a tension spring 1373. One end of the tension spring 1373 is connected to the wiping plate 137, and the other end is connected to the circular base plate 131. The tension spring 1373 is initially in a stretched state. Therefore, when wiping is not required, the tension spring 1373 pulls the wiping plate 137 upward, as far away from the ground as possible. When wiping is required, the lifting cylinder 1391 drives the lifting plate 139 to press down. The lifting plate 139 drives the third hollow shaft 138 to press down, which in turn drives the wiping plate 137 to press down, and the wiping plate 137 drives the wiping cloth to press down for wiping.

[0049] Compared with existing technologies, the intelligent household sweeping robot of the present invention features a sweeping component 110 on the left side of its bottom that rotates clockwise, and a sweeping component 110 on the right side that rotates counterclockwise. The two sweeping components 110 rotate towards each other, thus concentrating dirt towards the bottom of the robot body 100 for cleaning, reducing the likelihood of debris being swept away, and improving cleaning efficiency. A rotating roller brush is installed inside the suction inlet 120. This rotating brush effectively cleans the area where dirt has been sucked in, resulting in a more thorough cleaning. Under the vacuum adsorption of the adsorption device, a negative pressure adsorption effect is formed around each sweeping antenna 112. When the sweeping component 110 rotates to clean, the negative pressure adsorption effect around the sweeping antenna 112 causes dust and small particles of dirt to gather near the sweeping antenna 112, preventing dust from rising and polluting the environment during cleaning, thus improving cleaning efficiency and avoiding dust accumulation during cleaning. To address the issue of flying debris, the robot body design improves the user experience. The brush connector 111 and the first hollow shaft 114 are connected by a thread, making disassembly and assembly convenient. This allows for easy removal of the brush connector 111 to clean the bristles 113. Once the bristles 113 are clean, the brush connector 111 can be reassembled back into the robot body 100, ensuring the bristles 113 are clean for the next cleaning cycle and guaranteeing a thorough cleaning effect each time. The snap-fit ​​connection between the second antenna assembly 1122 and the first antenna assembly 1121 facilitates easy disassembly and assembly. Replacing only the second antenna assembly 1122 allows for partial replacement of the bristles 113, saving materials and costs. The circular base plate 131 drives the wiping cloth to rotate and wipe, improving the wiping effect and resulting in a cleaner floor. The wiping plate 137 presses the wiping cloth down, increasing wiping friction and further enhancing the wiping effect, leading to a cleaner floor.

[0050] The above description is only a preferred embodiment of the present invention and does not limit the patent scope of the present invention. Any modifications, equivalent substitutions and improvements made within the concept of the present invention should be included within the patent protection scope of the present invention.
