Background technique

The early floor cleaning tools used by people were brooms, mops, floor wipes, etc. These tools mainly relied on people's manual operation to complete the cleaning work. With the advancement of science and technology, people's requirements for floor cleaning tools have gradually increased. The first thing that appeared was the vacuum cleaner, which relies on electricity to supply energy and generates negative pressure to absorb garbage, dust, etc. on the ground. Classified from the cleaning methods and the circulation paths of small particle garbage and large particle garbage, this type of technology is usually classified as air and dust circulation technology. However, due to the limitations of its working principle, vacuum cleaners cannot clean some garbage and stains that are firmly attached to the ground. Therefore, new "water and dust circulation" floor scrubbers have emerged, which use the operation of the motor to drive the cleaning cylinder to wipe the floor. The cleaning cylinder usually adopts a sponge cylinder structure. At the same time, the floor cleaner will also be equipped with a water supply system and a sink to clean the cleaning cylinder, thereby perfectly cleaning the floor. In order to clean the cleaning cylinder, a closed cleaning space connected to the water supply system is usually set up to clean the partial roller, provide clean water to clean the cleaning cylinder, and then pump away the sewage after cleaning the cleaning cylinder.

In the rear direction, it rotates counterclockwise in the same direction as the first drum to clean the first drum; a transfer filter bin is provided on the housing, and collects and filters the filtered water through a water tank provided on the housing. The sewage produced by the first drum. By setting a brush roller behind the sponge roller, the sponge roller can be cleaned in time, so that the sponge roller is always kept clean, thereby ensuring the cleaning effect. By setting up a transfer filter chamber in the cleaning head, the sewage generated after the cleaning head is self-cleaned is filtered to ensure the self-cleaning effect of the cleaning head.

The higher part in the middle is the clean water inlet. The entire cleaning chamber is in a trough-shaped cleaning chamber. There are no other ventilation holes, so when the user manually drags the cleaning head, the clean water port may spray clean water mixed with air. Since the cleaning chamber is closed, the sewage return port will eventually suck the air sprayed from the water spray port back to the sewage passage. In this case, reducing the return efficiency of sewage will also reduce the working efficiency of the air pump for sucking sewage. The spraying of clean water mixed with air will cause the amount of water sprayed into the cleaning cavity to be uneven, and the amount of water soaked into the sponge roller will naturally be uneven. The sponge roller rotates at a high speed, and the water squeezed out by the water squeeze strip after one rotation Sewage will naturally be uneven. When the clean water nozzle is mixed with gas, a large number of bubbles will often be generated in the clean water flow. As the clean water washes the surface of the sponge roller, the large bubbles will be reduced into small bubbles. Some bubbles will burst and produce a certain amount of noise. Uneven water flow spraying on the sponge drum will also produce a certain amount of noise, and the air pump sucking sewage mixed with the steam drum will also produce noise.

In order to solve the above problems, it is necessary to find a solution that can timely release the gas pressure in the clean water mixed with gas ejected from the water spout, so as to further alleviate the uneven water flow and further reduce the noise.

Figure 7 is a schematic diagram of the internal pipeline connection of the cleaning head of the utility model cleaner with the housing body hidden. Figure 8 is a schematic diagram of the internal pipeline connection of the cleaning head of the utility model cleaner with only the bottom shell of the housing body retained. Figures 7 and 8 show the layout and connections of the cleaning head, part of the water pump built into the fuselage, the transfer bin, and related water flow pipelines and exhaust pipelines.

In some embodiments, as shown in FIGS. 7 and 8 , the end opening of the sewage channel 120 (not shown in the drawings) is connected to the water inlet 133 of the transfer compartment 13 (because the housing body is hidden in FIG. 7 10 In order to clearly express the connection between the relevant pipelines of the transfer warehouse 13 and the pipelines of other water and gas pipelines, combined with Figures 2 and 3, and the aforementioned technical solutions, the end of the sewage channel 120 must be connected to the transfer warehouse 13). The transfer warehouse is covered with a pipe joint (not shown in the drawing) at the top inside the casing body 10. One end of the transfer warehouse exhaust pipe 131 is connected to the pipe joint, and the other end of the transfer warehouse exhaust pipe 131 is bypassed. The aforementioned cleaning brush assembly 6 and garbage box 7 are wound up from the bottom of the cleaning head housing body and re-extended into the arc-shaped groove (not shown in the drawing) at the bottom of the bottom plate of the left side plate 12 . The air pressure released from the cleaning tank is collected into the transfer chamber 13 along the cleaning tank exhaust pipe 132 , and finally the air pressure in the transfer chamber 13 can be released to the surface of the cleaning roller 2 through the transfer chamber exhaust pipe 131 . A sewage pump 9 is provided on the lower left side of the cleaner body near the hinge. The suction port of the sewage pump is connected to a water tank outlet pipe 92. The air outlet of the sewage pump is connected to a sewage pump exhaust pipe 93. The sewage pump exhaust pipe 93 It is connected to the aforementioned clean water channel 110 through a fork-shaped tee 83. One of the two branch interfaces of the fork-shaped tee 83 is connected to the sewage pump exhaust pipe 93, and the other is connected to the water pump outlet clean water pipe 82. The collection port is connected to the cleaning tank water injection pipe 84, and the cleaning tank water injection pipe 84 is connected to the aforementioned clean water channel 110. Because the clean water pump 8 of the cleaner works intermittently and the space of the aforementioned cleaning tank is large enough, the air extracted by the sewage pump 9 is sent into the clean water channel 110 without affecting the actual clean water flow rate. On the one hand, the air in the cleaning tank will be absorbed by the pores on the surface of the cleaning roller 2, and on the other hand, it will be discharged to the outside of the cleaning head along the pressure relief channel. The transfer warehouse 13 is provided with a filtering device (not shown in the drawings). The bottom of the transfer warehouse 13 is also provided with a pipe joint (not shown in the drawings). One end of the sewage pumping pipe 91 is connected to the pipe joint. The sewage pumping pipe The other end of 91 is connected to the sewage inlet of the water tank (not shown in the accompanying drawing). When the sewage pump 9 is working, the air outlet of the sewage pump discharges air outward, and the discharged air finally enters the cleaning tank along the sewage pump exhaust pipe 93, the fork-shaped tee 83, the cleaning tank water injection pipe 84, and the clean water channel 110. The air enters the pores on the surface of the cleaning roller 2 with the scouring force of the water, and the other part of the air is discharged from the cleaning tank exhaust hole 16 and follows the cleaning tank exhaust pipe 132, the transfer warehouse 13, and the transfer warehouse exhaust pipe 131 in sequence. Finally, the air pressure at one end of the transfer bin exhaust pipe 131 close to the shovel bar 5 is released to the surface of the cleaning roller 2 . The suction port of the sewage pump sucks the air in the sewage chamber of the water tank. After the air in the sewage chamber is exhausted, the sewage that has been filtered by the transfer bin is continuously sucked along the sewage pumping pipe 91 into the sewage chamber of the water tank. As shown in Figure 8, after the housing body 10 is hidden, the sewage channel maintenance plate 122 on the left side panel 12 is very close to the transfer bin water inlet 133. In fact, the end of the sewage channel 120 must be connected through the transfer bin water inlet 133. Go to transit warehouse 13.

In some embodiments, as shown in Figures 2, 3, and 7, the cross-sectional width and height of the sewage flow channel 120 are larger than the width and height of the clean water channel 110. Since the exhaust pipe 93 of the sewage pump and the clean water outlet pipe 82 of the water pump are converged into the cleaning tank water injection pipe 84 through the fork-shaped tee 83, a certain amount of air will inevitably be mixed into the cleaning tank water injection pipe 84 if clean water flows intermittently in the clean water channel. In this way, the cross-sectional width and height of the sewage flow channel 120 are larger than the width and height of the clean water flow channel 110, which is conducive to removing the excess air when the surface of the cleaning roller 2 in the cleaning tank cannot absorb the mixed air in time. Continue to discharge along the sewage channel to the transfer warehouse.

In some embodiments, as shown in Figures 2, 3, 4, and 7, the open cleaning space also includes a sink flip cover 15 that can be detached from the top, and a removable cover is also provided directly above the cleaning sink. Sink flip cover15. Although the transfer bin 13 has a certain ability to filter and accommodate fine-grained solid waste, since the water squeezing strip 3 is volleyed close to the extended portion (not shown in the drawing) of the surface of the cleaning roller 2, multiple filtering through holes are evenly distributed on it (the drawing is attached) (not marked), it is inevitable that some fine-grained garbage that has passed through the filtering holes will be deposited on the side of the extended part away from the cleaning roller. When the fine-grained garbage is deposited to a certain extent, it will definitely reduce the filtration of the extended part of the water squeezing strip 3. efficiency, which in turn affects the flow rate of the cleaning and mixed water in the entire cleaning tank, which further affects the cleaning efficiency of the cleaner. At this time, by opening the sink flip cover 15 from the top of the casing body 10 of the cleaner, the water squeezing bar can be easily cleaned. After cleaning, the cleaning ability of the cleaner can be quickly restored.
