Description

Technical Field

[0001] This utility model relates to the field of floor scrubbing machine technology, and in particular to a floor scrubbing machine. Background Technology

[0002] Floor scrubbers are devices used to clean floors and simultaneously collect wastewater into a wastewater tank. They are environmentally friendly, clean, and efficient. The amount of wastewater in the tank needs to be monitored to determine whether drainage and cleaning are necessary. Traditional floor scrubbers typically use a water level probe inside the wastewater tank for detection. However, during operation, the wastewater surface can fluctuate, leading to false alarms. Furthermore, the presence of detergent in the wastewater can cause foaming, further contributing to misjudgments by the water level probe. Utility Model Content

[0003] The present invention aims to at least partially solve one of the aforementioned technical problems in the related art. Therefore, the present invention proposes a floor scrubbing machine.

[0004] To achieve the above objectives, the technical solution of this utility model is as follows:

[0005] The floor scrubbing machine according to an embodiment of the present invention includes a wastewater tank, an induction pipe, and a pipe level sensor. A water level sensing hole is provided on the side wall of the wastewater tank. The induction pipe is located outside the wastewater tank. The inlet end of the induction pipe is connected to the water level sensing hole, and the outlet end of the induction pipe is connected to the outside. The pipe level sensor is connected to the induction pipe, and the installation position of the pipe level sensor is not higher than the water level sensing hole.

[0006] The floor scrubbing machine according to the embodiments of this utility model has at least the following beneficial effects:

[0007] This invention features a water level sensing hole on the side wall of a wastewater tank, connected to a pipe level sensor outside the tank via a sensing pipe. When the wastewater level reaches the sensing hole, wastewater flows into the sensing pipe and the pipe level sensor. Upon detecting a full tank, the pipe level sensor triggers an alarm and shuts down the machine. A small amount of wastewater flowing through the pipe level sensor flows directly to the ground or the roller brush. The pipe level sensor is not installed inside the wastewater tank and does not directly contact the liquid surface. Even if foam reaches the sensing hole, it will not trigger the pipe level sensor, preventing false alarms caused by foam. Furthermore, the pipe level sensor has an adjustable response delay; even if the wastewater surface sloshes and a small amount of water enters the sensing pipe, it will not trigger the pipe level sensor, preventing false alarms caused by machine movement.

Detailed Implementation

[0023] The embodiments of this utility model are described in detail below. Examples of these embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals denote the same or similar elements or elements having the same or similar functions throughout. The embodiments described below with reference to the accompanying drawings are exemplary and intended to explain this utility model, and should not be construed as limiting this utility model.

[0024] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0025] Reference Figure 1-3 A floor scrubbing machine includes a wastewater tank 100, a sensing pipe 200, and a pipe level sensor 300. The wastewater tank 100 has a water level sensing hole 110 on its side wall. The sensing pipe 200 is located outside the wastewater tank 100. The inlet end of the sensing pipe 200 is connected to the water level sensing hole 110, and the outlet end of the sensing pipe 200 is connected to the outside. The pipe level sensor 300 is connected to the sensing pipe 200, and the installation position of the pipe level sensor 300 is not higher than the water level sensing hole 110.

[0026] In some embodiments of this utility model, a water-retaining wall 120 is provided inside the sewage tank 100. The water-retaining wall 120 and the side wall of the sewage tank 100 where the water level sensing hole 110 is located form a water-retaining cavity 121. The water level sensing hole 110 is located inside the water-retaining cavity 121. A water outlet 122 is provided on the side wall of the water-retaining cavity 121 to allow water from the sewage tank 100 to enter the water-retaining cavity 121. When the water level in the sewage tank 100 rises slowly and steadily, water will flow into the water-retaining cavity 121 through the water outlet 122, and then into the sensing pipe 200, triggering the pipe level sensor 300 to alarm. This is a normal full-water detection. When the water in the sewage tank 100 shakes or waves, most of the shaking waves will be blocked by the water-retaining wall 120. Only a small amount of water can enter the water-retaining cavity 121 through the water outlet 122, greatly reducing the frequency and amount of sewage entering the sensing pipe 200 when it is not full due to shaking.

[0027] In some embodiments of this utility model, the bottom of the water inlet 122 is higher than the bottom of the water level sensing hole 110. The water level sensing hole 110 is the actual water level line that triggers the sensor alarm. The bottom of the water inlet 122 is the lowest point of the inlet of the sewage tank 100 into the water-blocking cavity 121. The fact that the bottom of the water inlet 122 is higher than the bottom of the water level sensing hole 110 means that the water level in the sewage tank 100 must first rise to a position higher than the water level sensing hole 110 (i.e., exceeding the actual trigger line) before it can start flowing into the water-blocking cavity 121 through the water inlet 122. This is equivalent to setting a "step" between the water level in the sewage tank 100 and the water level sensing hole 110, raising the threshold for sewage to enter the water-blocking cavity 121, and further preventing machine shaking from causing misjudgment.

[0028] In some embodiments of this utility model, a floor brush is included. The floor brush includes a housing 400, a sewage tank 100 is horizontally installed at the rear of the housing 400, a water level sensing hole 110 is opened on the right wall of the sewage tank 100, and a pipeline level sensor 300 and a sensing pipeline 200 are installed on the right side of the housing 400.

[0029] In some embodiments of this invention, the wastewater tank 100 is detachable from the housing 400. The housing 400 has a receiving cavity with its opening located on the left side. The wastewater tank 100 can be inserted into the receiving cavity through the opening. The wastewater tank 100 is a side-pull type, which facilitates the user in removing the wastewater tank 100 to empty the wastewater. Both removal and installation are convenient. Furthermore, traditional water level probes are directly installed inside the wastewater tank 100, which limits the detachability of the wastewater tank 100. The pipeline level sensor 300 of this invention is fixed to the right side of the housing 400 and is not removed with the wastewater tank 100.

[0030] In some embodiments of this utility model, a groove 500 is provided on the right wall of the accommodating cavity. The groove 500 is connected to the sensing pipe 200. The water level sensing hole 110 extends outward to form a column, which is inserted into the groove 500. A sealing ring 600 is provided between the inner peripheral wall of the groove 500 and the outer peripheral wall of the column. When the sewage tank 100 is inserted, the water path connection and sealing between the water level sensing hole 110 and the sensing pipe 200 are completed through the column, the groove 500, and the sealing ring 600.

[0031] In some embodiments of this invention, the front of the housing 400 is formed with a roller brush cavity for mounting the roller brush, and the outlet end of the sensing pipe 200 extends into the roller brush cavity. When the pipe level sensor 300 is triggered, a small amount of sewage needs to be discharged. By extending the outlet end of the sensing pipe 200 into the roller brush cavity, the sewage is accurately guided into the working area of ​​the roller brush, without adding new pollution.

[0032] In some embodiments of this utility model, a clean water tank 700 is also included, which is an integral structure with the wastewater tank 100. The integrated tank structure allows the clean water tank 700 and the wastewater tank 100 to be pulled out at once, so that the user can complete the function that the existing floor scrubber requires two actions to perform, namely wastewater dumping and clean water filling, by simply removing and placing the tank once.

[0033] In some embodiments of this utility model, a suction port and a suction channel 410 are formed on the housing 400. The suction port is located at the front of the housing 400, and the suction channel 410 is located on the right side of the housing 400. The sewage tank 100 is provided with a water inlet 130 on the right side. The water inlet 130 is located above the water level sensing hole 110. The water inlet end of the suction channel 410 is connected to the suction port, and the water outlet end of the suction channel 410 is connected to the water inlet 130.

[0034] In some embodiments of this utility model, a water outlet 140 is provided on the left side of the sewage tank 100, and a sealing cover 141 is provided on the top of the water outlet 140. The water in the sewage tank 100 can be poured out through the water outlet 140, or it can be poured into clean water through the water outlet 140 to clean the inside of the sewage tank 100.

[0035] Although embodiments of the present invention have been shown and described, those skilled in the art will understand that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the claims and their equivalents.
