Description

Technical Field

[0001] This utility model relates to the field of ground cleaning robot technology, and in particular to a ground cleaning robot with ultraviolet disinfection. Background Technology

[0002] Mopping robots are suitable for floors with minimal debris and do not require clean or smooth surfaces. However, research in this area started relatively late. As a key research area in the cleaning robot field in recent years, many technical challenges remain to be overcome. Due to the need to consider automatic cleaning of the mop and post-treatment of wastewater, most existing products are semi-automatic, requiring manual assistance. Currently, their development is still immature. Mopping robots employ two mopping methods: active and passive. Passive mopping robots have the mop fixed to the bottom of the robot to ensure effective contact with the floor. As the robot moves forward, it passively drives the mop to wipe the floor and perform a dust-pushing action. Since water production is pre-controlled, little water remains on the floor after wiping, eliminating the need for collection. This method is easy to implement but has poor cleaning results, and the mop easily gets dirty. To maintain cleaning effectiveness, the mop needs frequent replacement. In contrast to passive mopping, active mopping involves mounting the mop cloth on movable parts of the robot, such as a moving or rotating mechanism. Motors drive the mop cloth relative to the floor to simulate the reciprocating wiping process when a person mops. This method has better cleaning results, but requires more driving components and a more complex structure. Utility Model Content

It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0015] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0016] Example

[0017] Please see Figure 1-2This utility model provides a technical solution: a floor cleaning robot with ultraviolet disinfection, including a Raspberry Pi. The input end of the Raspberry Pi is electrically connected to a drive motor, and the output end of the Raspberry Pi is electrically connected to an ultrasonic sensor, an indicator light, a 12V power supply, and a water tank. The output end of the Raspberry Pi is also electrically connected to a hair dryer, a mop head, a front brush, and a water spray head. Two sets of ultrasonic sensors are set at the front of the robot and one set at the rear of the robot. The robot is equipped with two standard wheels and one ball wheel, a vacuum cleaner, two sets of front brushes, three UVC germicidal lamp units installed on the top of the robot (the UVC germicidal lamp units are detachable), and two UVC germicidal lamps installed at the bottom. The robot is powered by a 12V power supply and uses an Arduino Uno board as the control host.

[0018] Working Principle: To achieve autonomous floor cleaning, the robot integrates multiple technologies, including ultrasonic obstacle avoidance, vacuuming, sweeping, mopping, and ultraviolet disinfection. The layout of the ultrasonic sensors allows the robot to effectively avoid obstacles and autonomously plan its path. Through the combined use of multiple brushes and a vacuum cleaner, the robot can remove dust and debris from the floor and perform a deep clean using the wet mopping function. Furthermore, the ultraviolet disinfection module can sterilize and purify the air, improving the hygiene quality of the indoor environment. Through the comprehensive application of these technologies, the robot can achieve all-around floor cleaning and disinfection, making it particularly suitable for environments requiring efficient disinfection.

[0019] The robot is equipped with two ultrasonic sensors at the front to detect obstacles and one ultrasonic sensor at the rear to enhance its environmental awareness. When the ultrasonic sensors emit sound waves and detect reflected waves, they calculate the time difference to determine distance, thus enabling obstacle avoidance. The robot has two standard wheels and one ball wheel, providing stable movement and steering. When the robot detects an obstacle, it can turn 360 degrees by rotating its wheels to avoid the obstacle and adjust its direction. A vacuum cleaner and two brushes at the front work together; the brushes guide dust and debris from the ground to the vacuum cleaner's suction inlet, and the vacuum cleaner then collects the debris into the dustbin. After cleaning, a mopping brush at the bottom of the robot can wet-mop the floor during the cleaning process, ensuring a deep clean. Three UVC germicidal lamp units are mounted on the top of the robot, and two more are located at the bottom. These lamps kill bacteria and viruses by emitting ultraviolet light, making them particularly suitable for hospitals or environments with infection risks. Because ultraviolet light is harmful to humans, the UVC lamps on the top of the robot are designed to be detachable, and patients must be out of the room during use. The system is powered by a 12V power supply and uses an Arduino Uno board as the control host to schedule the operation of various sensors and actuators. By receiving sensor data and issuing control commands, the Arduino enables the robot to perform functions such as autonomous obstacle avoidance, cleaning, and disinfection.

[0020] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
