Description

Technical Field

[0001] This utility model belongs to the field of floor cleaning equipment. Background Technology

[0002] A floor cleaning machine is a cleaning appliance capable of performing various cleaning functions on floors, such as vacuuming and scrubbing. Nowadays, floor cleaning machines are often equipped with a self-cleaning base. The floor brush is placed in this base, and the brush's rollers are immersed in the water, constantly washing away dirt as they rotate. However, the wastewater tank and suction channel of floor cleaning machines often accumulate large amounts of wastewater and debris, requiring regular manual cleaning. During these cleaning intervals, bacteria can proliferate. The suction channel, as the main channel for drawing in wastewater and dirt, also accumulates a lot of grime, posing a hygiene risk. These factors can lead to serious hygiene problems, causing the floor cleaning machine to wear out quickly and significantly shortening its lifespan. Furthermore, after the brush completes its self-cleaning process, it needs to air dry. During this time, bacteria can easily grow in the self-cleaning base and on the brush itself, potentially producing unpleasant odors and hindering future use. Summary of the Invention

[0023] Reference Figure 1 A type of floor cleaning equipment, comprising a floor cleaning machine 100 and a self-cleaning base 200.

[0024] like Figure 2As shown, the floor cleaning machine 100 includes a floor brush 110 and a main unit 120, with the floor brush 110 pivotally connected to the bottom of the main unit 120. The floor brush 110 includes a floor brush body 111 and a floor scrubbing roller brush 112, with a roller brush chamber for accommodating the floor scrubbing roller brush 112 formed on the front side of the floor brush body 111. The main unit 120 is equipped with a clean water tank 121 and a wastewater tank 122. It also has a suction module 125 inside, which connects the floor brush 110 and the wastewater tank 122 through a suction channel. The clean water tank 121 provides cleaning water for the floor brush 110's scrubbing roller brush 112, so that the surface of the scrubbing roller brush 112 is wetted to wipe and clean the stains on the floor. When the suction module 125 is working, it creates negative pressure in the wastewater tank 122, which generates suction force that is transmitted through the suction channel to the suction port 113 of the floor brush 110. All the garbage on the floor that the floor brush 110 passes over and the wastewater generated by the scrubbing roller brush 112 after cleaning the floor are temporarily stored in the wastewater tank 122 through the suction channel. Specifically, the floor brush body 111 is provided with a first sealing structure to prevent water from entering the interior, and the floor cleaning roller brush 112 is provided with a second sealing structure to prevent water from entering the interior. The first sealing structure includes a sealing strip arranged around the edge of the floor brush body 111 housing assembly and a sealing ring arranged at the joint edge for components exposed on the surface of the floor brush body 111. In this embodiment, the motor that drives the floor cleaning roller brush 112 to rotate is arranged inside the floor cleaning roller brush 112. Therefore, the second sealing structure includes multiple sealing rings arranged inside the cylinder of the floor cleaning roller brush 112 and an oil seal for wiring connection.

[0025] like Figure 3 , Figure 4 As shown, the self-cleaning base 200 is provided with a cleaning tank 210 for accommodating the floor brush 110 of the floor cleaning machine 100. The safety water level line in the cleaning tank 210 is higher than the height of the floor cleaning roller brush 112. A detection probe 220 for detecting the safety water level during self-cleaning is arranged on the side wall of the cleaning tank 210.

[0026] The self-cleaning base 200 is also provided with a water treatment module 230 for connecting to the main unit 120 of the floor cleaning machine 100. The water treatment module 230 includes a sewage treatment water passage 231, a first water supply water passage 232, and a second water supply water passage 233. The sewage treatment water passage 231 is connected to the sewage tank 122, the first water supply water passage 232 is connected to the clean water tank 121, and the second water supply water passage 233 is provided with a second water supply port 243 that connects to the cleaning tank 210.

[0027] Once the floor cleaning machine 100 is placed on the self-cleaning base 200, it can perform a comprehensive self-cleaning process. Figure 7 As shown, the working method is as follows: including,

[0028] Step 1: Place the floor cleaning machine 100 on the self-cleaning base 200, so that the floor brush 110 is housed in the cleaning tank 210, and connect the main unit 120 to the water treatment module 230 on the self-cleaning base 200 to start the self-cleaning operation.

[0029] Step 2: The sewage tank 122 of the main unit 120 is emptied through the sewage treatment water passage 231 of the water treatment module 230;

[0030] Step 3: The second water supply line 233 of the water treatment module 230 supplies water to the cleaning tank 210 until the water level of the cleaning tank 210 reaches the safe level and submerges the entire floor cleaning roller 112, then the water supply stops.

[0031] Step 4: The floor brush 110 is activated and the floor cleaning roller brush 112 starts to rotate, which drives the water in the cleaning tank 210 to form a water flow to rinse and clean the surface of the floor cleaning roller brush 112.

[0032] Step 5: After cleaning is completed, the floor cleaning roller 112 stops rotating, and the suction module 125 of the main unit 120 works to use the suction port 113 of the floor brush 110 to suck the cleaning water in the cleaning tank 210 into the sewage tank 122 through the suction channel.

[0033] Step 6: After emptying the sewage tank 122 again using the sewage treatment water line 231, complete the first flushing of the suction channel and the sewage tank 122; and inject clean water into the cleaning tank 210 again using the second water supply line 233.

[0034] Step 7: The suction module 125 of the main unit 120 works again to suck the clean water in the cleaning tank 210 into the sewage tank 122 to rinse the inside of the sewage tank 122.

[0035] Step 8: Empty the sewage tank 122 again using the sewage treatment water circuit 231 to complete the second flushing of the suction channel and the sewage tank 122.

[0036] Step 9: Use the first water supply circuit 232 to replenish the clean water tank 121 with clean water, and end the self-cleaning process.

[0037] After the floor cleaning machine 100 performs self-cleaning using the above-mentioned working method, the entire suction system and the floor cleaning roller brush 112 of the floor cleaning machine 100 can be thoroughly cleaned, reducing hygiene problems caused by bacterial growth and thus extending the service life of the floor cleaning machine 100.

[0038] As a preferred embodiment of this utility model, in order to further solve the problem of water remaining inside the self-cleaning brush 110 and the cleaning tank 210, this utility model provides a step-by-step solution, such as... Figure 6As shown, to address the issue of water accumulation inside the cleaning tank 210, the bottom wall of the cleaning tank 210 is inclined forward, forming a cleaning position 211 for mounting the floor cleaning roller brush 112 on the front side of the cleaning tank 210. On one hand, this concentrates water at the floor cleaning roller brush 112, allowing it to be thoroughly rinsed and generating a large flow of water to wash the brush body 111. On the other hand, the water concentrated at the floor cleaning roller brush 112 facilitates the suction port 113 to draw water from the cleaning tank 210, thereby completely drying the water in the cleaning tank 210. To address the issue of the floor cleaning roller and brush body 111 remaining wet after cleaning, a drying module is provided inside the self-cleaning base 200. The drying module includes a heating device 270, which is arranged on the bottom wall at the front side of the cleaning tank 210. The heating device 270 heats the fabric surface on the floor cleaning roller to dry it, and the floor cleaning roller brush 112 can also rotate to cooperate with the heating device 270. Furthermore, the drying module includes a hot air device 280, which includes a hot air blower 281 and a hot air channel. One end of the hot air channel is a hot air inlet 285 connected to the hot air blower 281, and the other end is a hot air outlet 286 connected to the front of the cleaning tank 210. Hot air generated by the hot air blower 281 is guided to the front of the cleaning tank 210 through the hot air channel and blown out from front to back to heat and evaporate the water in the entire floor brush 110. Furthermore, to prevent water from entering the self-cleaning base 200 through the hot air outlet 286, the hot air channel includes a first air guide 282 formed below the bottom wall of the cleaning tank 210, a second air guide 283 and a third air guide 284 arranged vertically on the front side of the cleaning tank 210. One end of the first air guide 282 is connected to the hot air inlet 285, and the other end is connected to the bottom of the second air guide 283. The top of the second air guide 283 is connected to the third air guide 284, and the bottom of the third air guide 284 is connected to the hot air outlet 286. The top openings of the second air guide 283 and the third air guide 284 are higher than the safe water level of the cleaning tank 210, thereby preventing water from entering the self-cleaning base 200 through the top openings of the second air guide 283 and the third air guide 284.

[0039] The drying process of the floor brush 110 can be combined with the self-cleaning process described above, forming step eight-I. This step is added between step eight and step nine. The drying process of the drying device is started only after the wastewater tank 122 is emptied. After drying is completed, the water tank 121 is replenished to complete the self-cleaning process.

[0040] As a preferred option, such as Figure 3 , Figure 5As shown, the water treatment module 230 is housed inside the self-cleaning base 200. A docking seat 240 is provided on the back side of the cleaning tank 210. The docking seat 240 is located below the main unit 120 and has a sewage receiving port 241 connecting to the sewage treatment water circuit 231 and a first water supply port 242 connecting to the first water supply circuit 232 arranged on its top. The main unit 120 has a drain port 123 connected to the sewage receiving port 241 and a drain port 123 connected to the first water supply port 242 at its bottom. The drain outlet 123 is connected to the wastewater tank 122, and the drain outlet 124 is connected to the clean water tank 121. The second water supply outlet 243 is located on the side wall of the docking seat 240. When the floor brush 110 of the floor cleaning machine 100 is placed in the cleaning tank 210 of the self-cleaning base 200, the drain outlet 123 and the drain outlet 124 at the bottom of the main unit 120 of the floor cleaning machine 100 automatically connect with the wastewater receiving outlet 241 and the first water supply outlet 242. Preferably, the drain outlet 123 is connected to the bottom of the wastewater tank 122, that is, the emptying of the wastewater tank 122 can be achieved entirely by gravity, without the need for additional hydrodynamic equipment.

[0041] There are multiple ways to connect the sewage outlet 123 and the sewage inlet 241. For example, the sewage outlet 123 is equipped with an electric control valve. After the sewage outlet 123 and the sewage inlet 241 are aligned and installed, the electric control valve is controlled to open the sewage outlet 123 to connect the sewage inlet 241 (not shown in the figure).

[0042] like Figure 2 , Figure 3 As shown, the preferred embodiment of the connection between the sewage outlet 123 and the sewage inlet 241 is achieved through a plug-in connector. Of course, the first water supply outlet 242 and the inlet 124 can also be connected in the same way. The sewage outlet 123 and the inlet 124 should be equipped with a connection valve, such as a lift valve plug, that is triggered to open when connected to the sewage inlet 241 and the first water supply outlet 242. This structure is a common technical method and will not be described in detail again.

[0043] Furthermore, the sewage treatment waterway 231 includes a sewage pipe 2311 and a sewage valve 2312 for controlling the flow of the sewage pipe 2311. The end of the sewage pipe 2311 forms an outlet 2313 that connects to the outside of the self-cleaning base 200. The outlet 2313 can be directly discharged into the sewer or discharged to the bathroom floor; or it can be connected to a wastewater tank to temporarily store the wastewater discharged from the sewage treatment waterway 231 (not shown in the figure).

[0044] Furthermore, the self-cleaning base 200 is equipped with a clean water pump 250. The inlet of the clean water pump 250 is connected to an external water source, which can be tap water or an additional clean water tank (not shown in the figure). The outlet is connected to the inlet of a three-way control valve 260. The first outlet of the three-way control valve 260 is connected to the first water supply port 242 through a conduit to form a first water supply path 232. The second outlet of the three-way control valve 260 is connected to the second water supply port 243 through a conduit to form a second water supply path 233. This arrangement not only saves costs but also simplifies the water path layout and the internal structure of the self-cleaning base 200.
