Description

Technical Field

[0001] The utility model relates to the technical field of floor scrubbers, in particular to a structure for preventing a floor scrubber from spraying or misreporting a sewage tank. Background Art

[0002] A floor scrubber is a cleaning machine suitable for cleaning hard floors and sucking out sewage at the same time, and taking the sewage away from the site. It has the advantages of environmental protection, energy saving, and high efficiency. Floor scrubbers include semi-automatic floor scrubbers, fully automatic floor scrubbers, hand-push floor scrubbers, and ride-on floor scrubbers. The main function of the sewage tank of a floor scrubber is to isolate and filter the garbage and dirt sucked into the floor scrubber to protect the main machine. The sewage tank of a floor scrubber achieves this function through a series of designs. It is usually composed of components such as a pre-filter, a probe, and a sewage backflow interception valve. These components work together to isolate and filter the garbage and dirt sucked into the floor scrubber. , preventing them from entering the main unit of the floor scrubber, thereby protecting the main unit. When the sewage in the sewage tank reaches the maximum value, the sewage will be conducted to the probes on both sides. At the same time, the floor scrubber will also have a display to remind the user to clean the sewage. This is achieved through the probe sensing device in the sewage tank. In addition, the design of the sewage tank also takes into account the convenience of user use. For example, if the capacity of the sewage tank is properly designed, the number of frequent cleanings by users can be reduced, which improves the convenience of use. At the same time, the structure and materials of the sewage tank have also been carefully designed to ensure its durability and easy cleaning, further enhancing the user experience.

[0003] However, the traditional sewage tank of the floor scrubber cannot meet people's needs, and has the following defects: First, there is no structure to prevent suction and spraying. For the floor scrubber used, the sewage is sucked into the sewage tank for filtration. When the machine is pushed and pulled back and forth, the sewage begins to ripple back and forth due to inertia. The splashing water is very likely to be carried away by the gas and poured into the suction motor, resulting in suction and spraying, causing secondary pollution of the device, and cleaning becomes very difficult, which greatly increases the harm to the device and reduces the service life of the device; second, there is no device to prevent false alarms. When performing floor scrubbing operations, the sucked sewage will splash everywhere due to the mixing of a large amount of gas. The splashed sewage adheres to the inner surface of the sewage tank and easily causes false alarms, resulting in users having to frequently clean the sewage tank, which increases the cleaning work time, which runs counter to the original intention of the product to bring convenience to users and brings users a bad user experience. Utility Model Content

[0020] Working principle: When using this utility model, start the floor washer. A certain high-speed airflow is generated by the operation of the vacuum motor on it. The high-speed airflow can keep the sewage tank in a vacuum state. The soft rubber strip in front of the arc-shaped water suction scraper at the rear of the floor washer can closely fit the ground. The collected sewage is adsorbed by the high-speed airflow in the vacuum environment, enters the lower cover assembly 3 through the dirt suction compartment 33 on the lower cover main body 31, and moves to the solid filtration compartment 18 through the high-speed airflow. At this time, due to the filter structure arranged at the bottom of the solid filtration compartment 18, dry garbage is separated and remains in the solid filtration compartment 18. After separating the upper cover main body from the lower cover main body, the dry garbage in the solid filtration compartment 18 can be cleaned in time to avoid affecting the device. The filtered gas and sewage flow into the sewage treatment compartment 19. The sewage stored in the sewage treatment compartment 19 will enter the sewage sedimentation compartment 32 due to the action of gravity. At this time, the separated gas is extracted from the gas extraction compartment 35 by the suction motor and discharged through the air filter 13 on the upper cover main body 11. When the device is in use, pull back the push-pull to continuously shake the sewage in the sewage sedimentation compartment 32, and it can be restricted by the splash-proof plate 22 on the anti-suction and spray component 2. The splash-proof plate 22 is installed and fixed to the socket 12 on the upper cover assembly 1 through the socket connection block 21 on it, preventing the overflowing sewage from entering the inside of the suction motor along with the gas and causing damage to the motor. At the same time, the induction probe 16 on the upper cover assembly 1 monitors the sewage in the sewage sedimentation compartment 32 in real time, can accurately sense the sewage volume and trigger the alarm setting to remind the user to clean the sewage in time. At the same time, the induction probe 16 is protected by the anti-false alarm silica gel cap 15 to prevent false alarms caused by sewage adhering to the surface of the probe when sewage splashes down from above; among them, the filter through-hole 23 is used to filter the sewage treatment compartment 19 to achieve double filtration of sewage and achieve true dry-wet separation. The connection through-hole 24 is used to connect the upper cover assembly 1 and the lower cover assembly 3 to effectively filter the sewage.
