Description

Technical Field

[0001] The utility model relates to the technical field of floor scrubbers, in particular to a sewage tank for floor scrubbers. Background Art

[0002] A floor scrubber is a device used to clean the floor. The current floor scrubbers have developed to have relatively complete functions. They are mainly divided into semi-automatic floor scrubbers, fully automatic floor scrubbers, hand-push floor scrubbers and ride-on floor scrubbers. However, the working principles of each type of floor scrubber are basically the same. They all spray clean water and detergent on the ground. While cleaning, they can also suck the sewage back into the sewage tank inside the floor scrubber to complete the cleaning process.

[0003] The sewage tank needs to be cleaned in time after it is full of water, so a full water detection device needs to be installed on the floor scrubber. Existing sewage tank full water detection devices usually use conductive detection. When the water is full to the conductive positive and negative positions, a voice prompt will appear, indicating that the sewage tank is full, the machine stops working, and the user cleans it in time. However, when there is obvious oil residue and the water tank is not full of water, false alarms are likely to occur, causing users to frequently stop working to clean the sewage tank during floor cleaning, affecting normal use. Utility Model Content

[0019] The present invention is further described and illustrated below in conjunction with specific embodiments and accompanying drawings:

[0020] Please refer to Figures 1 to 3A sewage tank for a floor scrubber includes a box body 10, the top of the box body 10 is open, a buoy body 20 is arranged inside the box body 10, a column 21 is arranged at the top of the buoy body 20, a magnet 22 is arranged at the top of the column 21, a box cover 30 is arranged at the opening of the box body 10, a guide sleeve 31 is arranged on the sliding sleeve of the peripheral wall of the buoy body 20, the top of the guide sleeve 31 is fixedly connected to the box cover 30, a guide channel 32 is opened at the position of the box cover 30 corresponding to the column 21, the column 21 is slidably inserted in the guide channel 32, and a Hall sensor module 40 is arranged above the box cover 30, and the position of the Hall sensor module 40 corresponds to the top of the guide channel 32.

[0021] In the above scheme, sewage enters the inner cavity of the box body 10, the water level gradually rises, and the buoy body 20 also gradually floats up along the inner wall of the guide sleeve 31. The column 21 gradually moves upward along the guide channel 32, and the magnet 22 at the top of the column 21 gradually approaches the Hall sensing module 40. When the water level reaches a preset height, the magnet 22 rises to the top of the guide channel 32. The Hall sensing module 40 is installed at a position corresponding to the top of the guide channel 32 of the floor scrubber frame. After sensing the magnetic field on the magnet 22, the Hall sensing module 40 issues a command, and a voice broadcast prompts that the sewage tank is full of water, please clean it immediately, and the entire machine stops working. It can perform detection when it is full of water to avoid false alarms and improve the user experience.

[0022] Please refer to Figure 2 The buoy body 20 is an internal hollow structure, a slot is provided at the top of the column 21, and the magnet 22 is arranged in the slot.

[0023] In the above scheme, the interior of the floating bridge body is hollow, which reduces the weight and ensures that it can float. In addition, the magnet 22 is arranged in the slot at the top of the column 21, which is convenient for installation and replacement.

[0024] Please refer to Figure 4 The bottom surface of the inner cavity of the box body 10 is provided with a water inlet pipe 11, and a water inlet is provided at a position corresponding to the bottom end of the water inlet pipe 11 on the bottom surface of the box body 10, and the top end of the water inlet pipe 11 extends to the upper part of the inner cavity of the box body 10. Further, a filter frame 50 is provided inside the box body 10, and a sleeve 51 is provided inside the filter frame 50, and the sleeve 51 is sleeved on the peripheral wall of the water inlet pipe 11.

[0025] In the above scheme, sewage enters the inner cavity of the box 10 from the water inlet pipe 11, and is first filtered through the filter frame 50 to collect debris in the sewage for easy cleaning. The length of the water inlet pipe 11 extends to the upper part of the inner cavity of the box 10 to ensure that the box 10 can accommodate a certain amount of sewage.

[0026] Please refer to Figure 2The box cover 30 is detachably fixedly connected to the box body 10. Specifically, a clamping ring 33 is provided at the bottom end of the box cover 30, and the outer peripheral wall of the clamping ring 33 is connected with the inner peripheral wall of the top end of the box body 10 by interference fit.

[0027] In the above solution, the box body 10 and the box cover 30 are detachably fixedly connected to facilitate subsequent cleaning of the box body 10. Specifically, in this embodiment, the box body 10 and the box cover 30 are connected by interference fit.

[0028] The utility model provides a sewage tank for a floor washing machine. When sewage enters the inner cavity of the tank, the water level gradually rises, and the buoy body also gradually floats up along the inner wall of the guide sleeve. The column gradually moves upward along the guide channel, and the magnet at the top of the column gradually approaches the Hall sensing module. When the water level reaches a preset height, the magnet rises to the top of the guide channel. The Hall sensing module is installed at a position on the floor washing machine frame corresponding to the top of the guide channel. After sensing the magnetic field on the magnet, the Hall sensing module sends a command, and a voice broadcast prompts that the sewage tank is full of water, please clean it immediately, and the whole machine stops working. It can perform detection when it is full of water to avoid false alarms, thereby improving the user experience.

[0029] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
