Description

Technical Field

[0001] The utility model relates to a cleaning robot, in particular to a cleaning robot capable of switching between sweeping and washing modes. Background Art

[0002] Existing cleaning robots generally offer two functions: sweeping and mopping. The sweeping function primarily relies on a roller brush assembly, which uses a corrugated roller brush to sweep dust to the center of the roller brush. The roller brush then uses negative pressure to draw the dust into the robot's dust bin. These cleaning robots are generally suitable for general use. However, in certain specialized environments, such as clothing production workshops and barbershops, these robots are less effective due to the presence of small and elongated debris. For example, in clothing production workshops, the floor often contains a large amount of fabric scraps and yarn, which can easily become entangled in the roller brush and prevent it from being drawn into the dust bin. In severe cases, they can even jam the roller brush, preventing it from rotating, thus affecting the cleaning function. Furthermore, existing cleaning robots typically incorporate a dust bin, a fresh water tank, and a wastewater tank. Each dust bin and wastewater tank require their own separate fans, pipes, and valves, complicating the overall structure of the cleaning robot, resulting in a bulky design and high equipment costs.

[0003] Based on the above-mentioned deficiencies, therefore, there is a need to develop a more suitable cleaning robot. Utility Model Content

[0004] The purpose of the utility model is to provide a cleaning robot that can switch between sweeping and washing modes, effectively reduces the size, has a simpler structure, and has lower equipment cost.

[0005] In order to achieve the above-mentioned purpose, the present invention provides a cleaning robot with dual-mode switching of sweeping and washing, including a robot body, a fan, a dust box, a single suction port assembly, a clean water tank, a sewage tank, a water pump, a suction scraper assembly and a rolling and mopping assembly. The robot body is provided with a accommodating cavity with an upper opening, the fan and the water pump are arranged on the robot body, the suction port of the single suction port assembly, the rolling and mopping assembly and the water suction port of the suction scraper assembly are respectively arranged at the bottom of the robot body in sequence along the front and rear directions of the robot body; among the dust box, the clean water tank and the sewage tank, the former and one of the latter two are arranged in the accommodating cavity; when the dust box is arranged at When in the accommodating cavity, the cleaning robot is in a sweeping mode, the suction port of the single suction port assembly is connected to the air inlet of the dust box, the air outlet of the dust box is connected to the inlet of the fan, and the outlet of the fan is connected to the outside world; when the clean water tank and the sewage tank are arranged in the accommodating cavity, the cleaning robot is in a washing mode, the water inlet of the water pump is connected to the clean water tank, and the water outlet of the water pump is connected to the rolling and mopping assembly; the washing mode and the sweeping mode use the same fan, the water suction port of the suction scraper assembly is connected to the sewage inlet of the sewage tank, the air outlet of the sewage tank is connected to the inlet of the fan, and the outlet of the fan is connected to the outside world.

[0006] Compared with the prior art, the present invention provides a housing cavity with an opening on the robot body, which can accommodate the dust box or clean water tank and sewage tank. At the same time, a fan single suction port assembly, a roller and mop assembly, and a water pump are provided in the robot body. When the dust box is installed and the fan is started, the negative pressure of the fan can be used to enable the single suction port assembly to directly suck garbage such as cloth scraps and wool into the dust box; when the clean water tank and sewage tank are installed and the water pump and fan are started at the same time, water can be supplied to the roller and mop assembly, and negative pressure can be used to enable the suction scraper assembly to suck water on the ground into the dust box to achieve floor washing. Therefore, the cleaning robot of the present invention can switch between sweeping and washing modes, effectively reducing the size of the cleaning robot, making the robot structure simpler, and reducing equipment costs. In addition, by using a single suction port assembly for negative pressure suction, cloth scraps and wool can be prevented from being entangled and unable to be sucked into the dust box, effectively improving the sweeping effect, and is suitable for use in clothing and other production industries.

[0007] Preferably, in sweeping mode, the dust box blocks the water inlet of the suction squeegee assembly, and in scrubbing mode, the sewage tank blocks the suction inlet of the single suction inlet assembly. This allows the fan to operate only in the current mode at different times, thus avoiding interference and ensuring functional stability. It also reduces the use of equipment, simplifies the structure, and reduces the size of the device.

[0008] Preferably, trigger switches are provided at the water inlet of the squeegee assembly and the suction port of the single suction port assembly. In sweeping mode, the dust box triggers the trigger switch at the water inlet of the squeegee assembly and releases the trigger switch at the suction port of the single suction port assembly, so that the control system does not activate the water pump and only activates the fan. In scrubbing mode, the sewage tank triggers the trigger switch at the suction port of the single suction port assembly and releases the trigger switch at the suction port of the squeegee assembly, so that the control system activates the water pump and the fan. This makes it easier for the control system to control the start and stop operations of various components, making control simpler and more convenient, and operation more stable.

[0009] Preferably, the single suction port assembly includes a housing, a scraper, a fixed cover, and a suction port. The scraper is disposed on the bottom surface of the housing. The fixed cover is connected to the bottom surface of the housing and clamps the scraper with the housing. The horizontal projection of the scraper is in the shape of a circular arc. The suction port is disposed in the housing and passes through the surface and bottom surface of the housing. The suction port is located in the middle of one side of the concave surface of the circular arc. By disposing the scraper on the housing so that the horizontal projection of the scraper is in the shape of a circular arc, and by using the fixed cover and the housing to jointly clamp the scraper, the scraper can be used to directly scrape garbage such as cloth scraps and wool on the ground, so that such garbage can be quickly concentrated in the middle of the concave surface of the scraper. Then, garbage such as cloth scraps and wool is directly sucked into the dust box of the cleaning robot through the suction port arranged in the middle of the concave side of the scraper bar. This cleaning method can avoid the problem of garbage such as cloth scraps and wool being entangled on the roller brush and unable to be sucked away by negative pressure. It can also prevent the roller brush from getting stuck. Therefore, the single suction port assembly of the utility model can quickly remove garbage such as cloth scraps and wool, and is suitable for garment factories and similar usage environments, with excellent cleaning effect.

[0010] Specifically, the single nozzle assembly further includes a base, and the housing is detachably mounted on the base. The base allows the housing to be quickly detached from or assembled to the base, making assembly and disassembly very convenient, facilitating cleaning of the housing and improving ease of use and maintenance.

[0011] Specifically, one of the housing and the base is provided with a guide block, and the other is provided with a guide rail. The guide block cooperates with the guide rail to allow the housing to slide relative to the base. The cooperation between the guide block and the guide rail makes the connection between the housing and the base simple and convenient, thereby improving the convenience of assembly and disassembly.

[0012] Specifically, the single suction port assembly further includes a locking mechanism, which is provided on the housing to position the housing, so that the housing can be quickly fixed to the housing, thereby improving the convenience of assembly.

[0013] Specifically, the locking mechanism includes a lock catch and a reset member. A sliding groove is provided at one end of the shell, the lock catch is slidably arranged in the sliding groove, and the reset member is arranged between the shell and the lock catch so that the lock catch extends toward the upper surface of the shell.

[0014] Specifically, a pressing position for pushing and pulling by fingers is recessed on the outward side of the lock buckle.

[0015] Specifically, the single suction port assembly further includes guide wheels, which are pivotally connected to both ends of the bottom surface of the shell. The guide wheels can support the shell, making the cleaning robot walk more stably and smoothly. BRIEF DESCRIPTION OF THE DRAWINGS

[0032] In order to explain the technical content, structural features and effects achieved by the present invention in detail, the following is a detailed description in conjunction with the embodiments and the accompanying drawings.

[0033] like Figures 1 to 7As shown, the cleaning robot 100 of the present invention includes a single suction port assembly 1, a robot body 2, a blower 3, a dust box 4, a side brush assembly 5, a clean water tank 6, a dirty water tank 7, a water pump 8, a suction scraper assembly 9, and a rolling and dragging assembly 10. The robot body 2 has a walking mechanism 22 to drive the entire cleaning robot 100 to move. The blower 3 and water pump 8 are disposed within the robot body 2. The single suction port assembly 1 is detachably mounted on the bottom of the robot body 2. The side brush assembly 5, the suction port 14 of the single suction port assembly 1, the rolling and dragging assembly 10, and the water suction port 91 of the suction scraper assembly 9 are sequentially disposed on the bottom of the robot body 2 along the front-to-back direction of the robot body 2. The robot body 2 is provided with a receiving chamber 21 with an upper opening. Of the dust box 4, the clean water tank 6, and the sewage tank 7, either the former or the latter is disposed within the receiving chamber 21; that is, the dust box 4 is disposed within the receiving chamber 21, or both the clean water tank 6 and the sewage tank 7 are disposed within the receiving chamber 21. When the dust box 4 is disposed within the receiving chamber 21, the cleaning robot 100 is in sweeping mode. The suction port 14 of the single suction port assembly 1 is connected to the air inlet 41 of the dust box 4 via a duct 141. The air outlet 42 of the dust box 4 is connected to the inlet 31 of the fan 3 via a duct 34. The outlet 32 of the fan 3 is connected to the exhaust port 2a on the rear side of the robot body 2 via a duct 33, thereby communicating with the outside world. The side brush assembly 5 is arranged on the bottom surface of the robot body 2 and located on both sides of the front of the single suction port assembly 1. The side brush assembly 5 can clean the garbage on both sides of the robot body 2 to the middle, so as to facilitate the single suction port assembly 1 to collect garbage. Figures 8 to 10As shown, when the clean water tank 6 and the sewage tank 7 are disposed in the accommodating chamber 21, the cleaning robot 100 is in a floor scrubbing mode. The water inlet of the water pump 8 is connected to the clean water tank 6 via a pipe 81, and the water outlet of the water pump 8 is connected to the roller-mopping assembly 10 via a pipe 82, so as to deliver clean water for floor scrubbing to the roller-mopping assembly 10. The water suction port 91 of the suction scraper assembly 9 is connected to the sewage inlet of the sewage tank 7 via a pipe 92, the air outlet of the sewage tank 7 is connected to the inlet 31 of the fan 3 via a pipe 34, and the outlet 32 of the fan 3 is connected to the exhaust port 2a on the rear side of the robot body 2 via a pipe 33, thereby communicating with the outside world. In sweeping mode, the dust box 4 blocks the water inlet 91 of the suction squeegee assembly 9 or the outlet of the pipe 92 connected thereto, preventing the suction squeegee assembly 9 from generating negative pressure. In scrubbing mode, the sewage tank 7 blocks the suction port 14 of the single suction port assembly 1 or the outlet of the pipe 141 connected thereto, preventing the single suction port assembly 1 from generating negative pressure. The utility model uses the same fan 3 for both sweeping and scrubbing modes. This allows the fan 3 to operate only on the current mode of use, avoiding interference and ensuring functional stability. This also reduces the amount of equipment used, simplifies the structure, and reduces the size of the device.

[0034] A trigger switch (not shown in the figure) is provided at the water suction port 91 of the suction scraper assembly 9 or the outlet of the pipe 92 connected thereto and the suction port 14 of the single suction port assembly 1 or the outlet of the pipe 141 connected thereto. In the sweeping mode, the dust box 4 triggers the trigger switch located at the water suction port 91 of the suction scraper assembly 9 or the outlet of the pipe 92 connected thereto and releases the trigger switch located at the suction port 14 of the single suction port assembly 1 or the outlet of the pipe 141 connected thereto, so that the control system does not start the water pump 8 and can only start the fan 3; in the washing mode, the sewage tank 7 triggers the trigger switch located at the suction port 14 of the single suction port assembly 1 or the outlet of the pipe 141 connected thereto and releases the trigger switch located at the water suction port 91 of the suction scraper assembly 9 or the outlet of the pipe 92 connected thereto, so that the control system can start the water pump and the fan at the same time.

[0035] See also Figures 13 to 16The single suction port assembly 1 includes a shell 11, a scraper 12, a fixed cover 13 and a suction port 14. The scraper 12 is arranged on the bottom surface of the shell 11 and can elastically contact the ground when working to scrape the ground. The fixed cover 13 is connected to the bottom surface of the shell 11 and clamps the scraper 12 with the shell 11. The horizontal projection of the scraper 12 is in the shape of an arc. The suction port 14 is arranged on the shell 11 and passes through the surface and bottom surface of the shell 11. The suction port 14 is located in the middle of the concave side of the arc. By arranging the scraper 12 on the shell 11, the horizontal projection of the scraper 12 is in the shape of an arc. The fixed cover 13 and the shell 11 are used to clamp the scraper 12 together, so that the scraper 12 can be used to directly scrape the garbage such as cloth scraps and wool on the ground, so that the garbage can be quickly concentrated in the middle of the concave side of the scraper 12. Then, the garbage such as cloth scraps and wool is directly sucked into the dust box 4 of the cleaning robot 100 through the suction port 14 provided in the middle of the concave side of the scraper 12. This cleaning method can avoid the problem of garbage such as cloth scraps and wool being entangled on the roller brush and unable to be sucked away by negative pressure, and can also prevent the roller brush from getting stuck. The single suction port assembly 1 also includes a base 15, and the shell 11 is detachably provided on the base 15. The base 15 is provided on the bottom surface of the robot body 2. By providing the base 15, the shell 11 can be quickly detached from the base 15, or can be quickly assembled to the base 15, so that assembly and disassembly are very convenient, which is conducive to cleaning the shell 11 and improves the convenience of use and maintenance. Specifically, either the housing 11 or the base 15 is provided with a guide block 111, while the other is provided with a guide rail 151. In this embodiment, the housing 11 is provided with guide blocks 111 on opposite sides, and the base 15 is provided with a guide rail 151. The guide rail 151 extends in the same direction as the length of the base 15. The guide blocks 111 cooperate with the guide rail 151 to allow the housing 11 to slide relative to the base 15; thus, the housing 11 can be inserted into the base 15 from one end, or removed from the base 15 from one end. The cooperation between the guide blocks 111 and the guide rail 151 makes the connection between the housing 11 and the base 15 simple and convenient, thereby improving the convenience of assembly and disassembly. The guide blocks 111 are protruding outwardly from opposite side edges of the shell 11 . The bottom surface of the base 15 is provided with a receiving groove 152 for receiving the shell 11 . The guide rails 151 are provided on opposite sides of the receiving groove 152 .

[0036] See also Figure 15The single suction port assembly 1 also includes a locking mechanism 16, which is provided on the shell 11 to position the shell 11. This allows the shell 11 to be quickly fixed to the shell 11, improving the convenience of assembly. The locking mechanism 16 includes a lock 161 and a reset member 162. A locking hole 153 is provided at a position corresponding to the lock 161 on the base 15. A sliding groove 11a is provided at one end of the shell 11. The lock 161 is slidably provided in the sliding groove 11a. The reset member 162 is provided between the shell 11 and the lock 161 so that the lock 161 extends toward the upper surface of the shell 11. When the shell 11 is installed on the base 15, the front end of the lock 161 is stuck in the locking hole 153, thereby locking the shell 11 and the base 15 to each other. Specifically, the lock 161 has a recessed pressing position 161a for pushing and pulling by fingers on the outward side. During operation, the lock buckle 161 can be manually pressed to disengage the lock buckle 161 from the locking hole 153 to achieve unlocking.

[0037] See also Figure 13 and Figure 15 The upper surface of the base 15 is provided with a connecting rod seat 154 that can be connected to the bottom surface of the robot body 2. The provision of the connecting rod seat 154 makes it easier to install the base 15 on the robot body 2, improving the convenience of assembly. In addition, the upper surface of the base 15 is also provided with a lifting frame 155 and a counterweight block 156 that can be connected to the robot body 2. This allows the single suction port assembly 1 to be installed on the robot body 2 more conveniently and stably.

[0038] See also Figure 14 and Figure 15 The single suction port assembly 1 further includes a guide wheel 17, which is pivotally connected to both ends of the bottom surface of the housing 11. Specifically, the guide wheel 17 includes a guide wheel seat 171 and a roller 172. The guide wheel seat 171 is fixed to both ends of the bottom surface of the housing 11, and the roller 172 is pivotally connected to the guide wheel seat 171 via a pivot shaft 172a. The central axis of the pivot shaft is perpendicular to the walking direction of the cleaning robot 100. The guide wheel 17 can support the housing 11, making the cleaning robot 100 move more stably and smoothly.

[0039] In summary and in combination with the above drawings, the working principle of the cleaning robot 100 of the present invention is described in detail below:

[0040] When sweeping is required, the dust box 4 is installed in the accommodating cavity 21, the robot body 2 is started, and the robot body 2 moves forward. At the same time, the side brush assembly 5 is started to draw the wool or cloth scraps on both sides toward the center. Furthermore, under the scraping of the scraper bar 12, the wool and cloth scraps are concentrated toward the middle of the concave surface of the scraper bar 12. At this time, the fan 3 is started, causing a negative pressure to be generated at the inlet of the fan 3, thereby generating a negative pressure at the suction port 14 and its vicinity, thereby causing the wool and cloth scraps located in the middle of the concave surface of the scraper bar 12 to be sucked into the dust box 4. After being filtered by the dust box 4, the purified gas is discharged from the exhaust port of the cleaning robot 100 without affecting the surrounding environment, while the wool and cloth scraps remain in the dust box 4. When the single suction port assembly 1 needs to be cleaned, the pressing position 161a is pressed to disengage the lock 161 from the locking hole 153. Thus, the lock 161 unlocks the housing 11. Then, the housing 11 is pulled out of the base 15. Finally, the housing 11 and the components connected to the housing 11 can be cleaned. After cleaning is completed, the housing 11 only needs to be inserted into the base 15 and locked, and the cleaning robot 100 can continue cleaning.

[0041] When the floor needs to be washed, the dust box 4 is pulled out of the accommodating chamber 21, and the sewage tank 7 and the clean water tank 6 are placed in the accommodating chamber 21. After the sewage tank 7 and the clean water tank 6 are placed in the accommodating chamber 21, the various inlets and outlets can be connected one by one. Afterwards, the robot body 2 is started, and the robot body 2 moves forward. At the same time, the water pump 8 is started, and the water pump 8 transports the clean water in the clean water tank 6 to the rolling and dragging assembly 10. The rolling and dragging assembly 10 cleans the floor as the robot body 2 moves. At the same time, the fan 3 is started, so that the suction scraper assembly 9 generates negative pressure, which can then absorb the sewage left on the floor after the rolling and dragging assembly 10 completes cleaning. The sewage then flows into the sewage tank 7 through the pipe 92 along with the airflow.

[0042] Compared to the prior art, the present invention provides a housing chamber 21 with an opening on the robot body 2. The housing chamber 21 can accommodate the dust box 4 or the clean water tank 6 and the sewage tank 7. Furthermore, a fan single suction port assembly 1, a roller-mopping assembly 10, and a water pump 8 are provided within the robot body 2. When the dust box 4 is installed and the fan 3 is activated, the negative pressure from the fan 3 can be used to allow the single suction port assembly 1 to directly suck garbage such as cloth scraps and wool into the dust box 4. When the clean water tank 6 and the sewage tank 7 are installed and the water pump 8 and the fan 3 are activated simultaneously, water can be supplied to the roller-mopping assembly 10, and the negative pressure can be used to allow the suction scraper assembly 9 to suck water from the ground into the dust box 4, thereby achieving floor washing. Therefore, the present cleaning robot 100 can switch between sweeping and washing modes, effectively reducing the size of the cleaning robot, making the robot structure simpler, and reducing equipment costs. In addition, by using the single suction port assembly 1 for negative pressure suction, it is possible to prevent cloth scraps and wool from being entangled and unable to be sucked into the dust box, thereby effectively improving the sweeping effect. Therefore, the utility model is suitable for garment factories and similar usage environments.

[0043] The robot body 2 involved in the cleaning robot 100 of the present invention also includes a walking mechanism 22 that can drive the cleaning robot to walk and a control circuit board that controls the start and stop of various electrical components. These structures are well known to ordinary technicians in this field and will not be described in detail here.

[0044] The above disclosure is only a preferred embodiment of the present invention and certainly cannot be used to limit the scope of rights of the present invention. Therefore, equivalent changes made according to the scope of the patent application of the present invention still fall within the scope covered by the present invention.
