[0002] A water level alarm device for a floor scrubber is an intelligent auxiliary device that monitors the water levels in the scrubber's fresh water and wastewater tanks in real time. When the water level falls below or rises above a preset safety threshold, the device immediately triggers an alarm system, alerting the operator through sound or light signals. This device not only improves the safety and convenience of floor scrubber operation but also effectively prevents equipment failures or poor cleaning results caused by abnormal water levels. The use of a water level alarm device makes floor scrubber operation more intelligent and user-friendly, providing a strong guarantee for cleaning work.

[0003] During the implementation of this application, it was found that the technology has the following problems: the existing floor scrubber water tank is not equipped with a corresponding water level alarm device, making it difficult to monitor the water level of the floor scrubber's clean water tank and sewage tank in real time. At the same time, the water tank components cannot be disassembled and cleaned, and dirt and bacteria are easily accumulated inside the water tank. The inability to disassemble and clean will cause hygiene problems.

[0004] Therefore, a water level alarm device for a floor scrubber is proposed. Utility Model Content

[0005] The purpose of the utility model is to provide a water level alarm device for a floor scrubber in order to monitor the water levels of the clean water tank and sewage tank of the floor scrubber in real time and effectively ensure the cleanliness of the interior of the water tank.

Specifically, through the cooperation of the above structures, the water level of the clean water tank of the floor washing machine can be monitored in real time, effectively avoiding problems such as equipment failure or poor cleaning effect caused by abnormal water level.

[0025] Reference Figure 1-Figure 5 The water tank 1 includes a water storage top cover 14 and a connecting layer 23. The bottom outer surface of the water tank 1 is integrally formed with the connecting layer 23. The left and right outer surfaces of the water tank 1 are each provided with a set of limit chambers 27. Specifically, the connecting layer 23 is used to limit the excessive descent of the float 22 to ensure the accuracy of the data of the water level monitor 21 on the float. Several groups of limiting grooves 13 are provided in parallel on the outer surfaces of the left and right sides of the water storage top cover 14. A fixing plate 16, a limiting plate 15 and a spring 17 are provided inside each group of limiting chambers 27. A group of fixing plates 16 are fixedly connected to the inner surface of each group of limiting chambers 27. A group of pressing members 12 are slidably provided between each group of fixing plates 16, and a group of springs 17 are provided around the periphery of each group of pressing members 12. Specifically, by pulling the corresponding pressing member 12 to activate the spring 17 on its periphery, the spring 17 drives the corresponding limiting plate 15 to move, so that the corresponding limiting protrusion 18 is disengaged from the position of the corresponding limiting groove 13, and the water storage top cover 14 is taken out to inject sufficient water into the water tank 1.

[0026] Reference Figure 1-Figure 5The two ends of each set of springs 17 are respectively connected to the outer surfaces of the corresponding fixing plate 16 and the limiting plate 15. The other end of each set of pressing parts 12 is provided with a set of limiting protrusions 18, and each set of limiting protrusions 18 is limitedly engaged with the corresponding limiting grooves 13. Specifically, after filling with water, the corresponding pressing part 12 is released to allow the spring 17 to drive the limiting protrusion 18 to rebound, and the water tank is restored to the closed state. By limiting the position of the limiting plate 15, the water tank assembly can be disassembled and cleaned, which can effectively clean the dirt and bacteria accumulated inside. A group of guide plates 19 are slidably provided on the inner surface of each water storage tank 1, and a group of connecting rods 20 are provided on the bottom surface of each group of guide plates 19. A group of floats 22 are provided at the other end of each group of connecting rods 20, and four groups of water level monitors 21 are evenly provided on the periphery of the floats 22. Specifically, the water level monitors 21 detect the liquid level inside the water tank. A storage device is provided inside the control device 9 to power the system, start the entire device, and judge whether the entire device is in a normal working state by observing whether the indicator light 24 is on.

Specifically, when the liquid level inside the water tank drops to a point where the water level monitor 21 can no longer detect the liquid level, the detection signal will be transferred to the control device 9. After receiving the command, the control device 9 controls the buzzer alarm 3 to sound an alarm.

[0028] The implementation principle of the water level alarm device for a floor scrubber in this application is as follows:

[0029] When a floor scrubber with a water level alarm device is used, the corresponding pressing piece 12 is pulled to activate the spring 17 on its periphery, and the spring 17 drives the corresponding limiting plate 15 to move, so that the corresponding limiting protrusion 18 is disengaged from the position of the corresponding limiting groove 13, and the water storage top cover 14 is taken out to inject sufficient water into the water tank 1, and the liquid level height is observed through the scale bar 11 on the observation window 10. After the water is filled, the corresponding pressing piece 12 is released to make the spring 17 drive the limiting protrusion 18 to rebound, and the water tank is restored to the closed state. By limiting the position limit of the limiting plate 15, the water tank assembly can be disassembled and cleaned, which can effectively clean the dirt and bacteria accumulated inside.

[0030] On the other hand, the water level monitor 21, display screen 26, indicator light 24 and buzzer 25 are electrically connected to the control device 9 through wires. A storage device is provided inside the control device 9 to power the system, start the entire device, and judge whether the entire device is in a normal working state by observing whether the indicator light 24 is on. At this time, the water level monitor 21 detects the liquid level inside the water tank. When the liquid level inside the water tank drops to a level where the water level monitor 21 cannot detect the liquid level, the detection signal will be transferred to the control device 9. After receiving the command, the control device 9 controls the buzzer alarm 3 to sound an alarm, thereby effectively avoiding problems such as equipment failure or poor cleaning effect caused by abnormal water level.
