[0002] The early ground cleaning tools used by people are brooms, mops, floor wipes, etc., which mainly rely on manual operation of people to complete the cleaning work. With the progress of science and technology, people's requirements for ground cleaning tools have gradually increased. First appeared is the dust collector, which relies on electric power supply and generates negative pressure to suck up garbage, dust and other garbage on the ground. From the cleaning means and the flow path of small particle garbage and large particle garbage, this kind of technology is usually classified as air dust circulation technology. However, due to the limitation of its working principle, the dust collector cannot clean some garbage and stains firmly attached to the ground, so a new "water dust circulation" floor washing machine appears, which drives the cleaning cylinder to wipe the ground through the operation of the motor. The cleaning cylinder usually adopts a sponge cylinder structure, and the floor cleaning machine is also equipped with a water supply system and a water tank to clean the cleaning cylinder, so as to perfectly realize the cleaning of the ground. In order to clean the cleaning cylinder, a closed cleaning space is usually provided to clean the local roller, clean water is provided to clean the cleaning cylinder, and then the sewage after cleaning the cleaning cylinder is pumped away.

[0004] Chinese patent CN114680747A discloses a cleaning head and a cleaning tool, the cleaning head comprising a shell, a first drum arranged in the shell for cleaning garbage, a second drum arranged behind the first drum in the rotation direction of the first drum and rotating counterclockwise with the first drum to clean the first drum, and a transfer filter bin arranged on the shell to collect sewage generated by filtering the first drum through a water tank arranged on the shell. By arranging a brush drum behind the sponge drum, the sponge drum can be cleaned in time, so that the sponge drum always remains clean, thereby ensuring the cleaning effect. By arranging a transfer filter bin in the cleaning head, the sewage generated after self-cleaning of the cleaning head is filtered, thereby ensuring the self-cleaning effect of the cleaning head. In addition, by using water dust conversion technology, the water in the cleaning tool is recycled multiple times, realizing self-cleaning of the sponge drum, and combining sweeping, mopping and washing together, especially for sticky garbage which is difficult to handle, the cleaning effect is excellent.

[0005] In the prior art, a groove-shaped cleaning cavity is arranged in a water dust circulating cleaner. One end of the cleaning cavity is a clean water inlet, and the other end is a sewage return port after the sponge roller is flushed. Or both ends of the cleaning cavity are clean water inlets, and the middle low part is a sewage return port after the sponge roller is flushed. Or both ends of the cleaning cavity are low sewage return ports after the sponge roller is flushed, and the middle high part is a clean water inlet. There is no other air hole in the entire groove-shaped cleaning cavity, which may cause the clean water inlet to spray clean water mixed with air when the user manually drags the cleaning head. Since the cleaning cavity is closed, the sewage return port will eventually also suck the air sprayed from the water outlet into the sewage passage, reducing the sewage return efficiency and the working efficiency of the air pump for sucking sewage. The spraying of clean water mixed with air may cause uneven water flow in the cleaning cavity, and the water flow on the sponge roller is also uneven. When the clean water outlet is mixed with gas, a large number of bubbles will be generated in the clean water flow, and the large bubbles will be reduced to small bubbles in the process of flushing the surface of the sponge roller with the clean water. Some bubbles will burst, and some noise will be generated. The uneven water flow sprayed on the sponge roller will also generate some noise, and the air pump sucking the sewage mixed with the gas pocket will also generate noise.

[0006] To solve the above problems, a scheme for timely releasing the gas pressure in the clean water mixed with gas sprayed from the water outlet of the cleaner is needed to further alleviate the uneven water flow and further reduce noise. SUMMARY

[0007] The main technical problem solved by the present application is to provide an open cleaning channel that can timely release the gas pressure in the clean water mixed with gas sprayed from the water outlet of the cleaner to further alleviate the uneven water flow of the cleaner and further reduce noise.

[0018] In one embodiment, the cleaning space further includes a flip cover that can be detached from the top, and after the flip cover is detached, the cleaning tank can be easily cleaned.

[0019] In a second aspect, the application also provides a cleaner, which includes a cleaning head provided with a housing, a cleaning roller provided in the housing, a cleaning brush for cleaning the surface of the cleaning roller, and a garbage box for collecting the cleaned garbage, and the cleaning head has an open cleaning channel provided in the cleaning head housing and inverted on the upper part of the cleaning roller, the cleaning head housing includes a left side plate clamping the cleaning roller, a right side plate, and a housing body connecting the left side plate and the right side plate, the cleaning channel includes a cleaning tank connected to a clean water channel and a sewage channel, and the cleaning space further includes a pressure relief channel communicating with the atmosphere.

[0020] In one embodiment, the cleaning tank is provided with a pressure relief hole at one end of the upper part, and the pressure relief hole is connected to the pressure relief channel.

[0021] In one embodiment, the clean water channel includes a clean water channel provided on the right side plate, and the sewage channel includes a sewage channel provided on the left side plate.

The cleaning head also has the aforementioned open cleaning channel.

[0031] Advantages of the present application:

[0032] 1. The exhaust outlet hole added to the upper part of the cleaning tank in the cleaner can let the clean water sprayed from the clean water outlet mixed with air, which is of no more benefit to the cleaning roller to wipe the surface of the object to be cleaned. It is beneficial to further exhaust the air to other areas outside the entire water flow loop, and the sewage return outlet can suck more proportion of sewage into the sewage return path, thereby improving the sewage return efficiency and the working efficiency of the air pump for sucking sewage.

[0033] 2. The spraying of clean water mixed with air can cause uneven water flow in the cleaning cavity, but after the mixed air is diverted by the exhaust passage, the water uniformity soaked into the sponge drum can be improved, and more air will not be forced into the pores of the sponge layer of the sponge drum with the clean water. The rotation speed of the sponge drum is relatively high, and the sewage squeezed out by the squeezing strip after one rotation will also be more uniform.

[0034] 3. When the clean water outlet is mixed with gas, a large amount of bubbles will be generated in the clean water flow. During the process of washing the surface of the sponge drum with the clean water, the large bubbles will be reduced to small bubbles, and some bubbles will burst, which will produce a certain noise. After the air mixed with the clean water is diverted by the exhaust passage, the water uniformity soaked into the sponge drum can be improved, and more air will not be forced into the pores of the sponge layer of the sponge drum, which can reduce the noise caused by the bursting of bubbles.

[0054] As shown in the prior art, Figure 1 The water squeezing strip 3 is installed on the housing 10 of the cleaning head 1 of the cleaner, and the water squeezing strip 3 squeezes the surface of the cleaning roller 2. The water squeezing strip 3 is installed on the vertical cleaning roller guard plate (not shown in the figure) on one of the end faces of the housing 10. The opposite side of the guard plate is provided with a vertical plate (not shown in the figure), and the water supporting strip 4 is installed on the vertical plate. The part of the surface of the water squeezing strip 3, the part of the surface of the cleaning roller 2, the part of the surface of the water supporting strip, the part of the surface of the vertical plate, and the part of the surface of the cleaning roller guard plate together enclose a washing groove (not shown in the figure) that allows clean water to continuously wash the upper surface of the cleaning roller. A detachable cover 15 is provided above the washing groove. The washing groove is in the shape of a "G" letter, and the hook of the "G" letter is the water dividing hook of the water squeezing strip. The opening of the "G" letter is directly opposite the surface of the cleaning roller 2 to be washed and the water supporting strip 4.

[0055] In the first aspect, Figure 2 Figure 8 ​As shown, the present invention provides an open cleaning channel, disposed in the cleaning head housing 1 of a cleaner equipped with a cleaning roller 2, and upside down on the upper part of the cleaning roller 2. The cleaning head housing 1 includes a left side plate 12 and a right side plate 11 for holding the cleaning roller 2, and a housing body 10 connecting the left side plate and the right side plate. The cleaning channel includes a cleaning tank and a clean water channel and a wastewater channel communicating with the cleaning tank. The cleaning channel also includes a pressure relief channel communicating with the outside atmosphere. The present invention also provides a cleaner, including a cleaning head, which is provided with a cleaning head housing 1, a cleaning roller 2 disposed in the cleaning head housing 1, a cleaning brush assembly 6 for cleaning the surface of the cleaning roller, and a garbage box 7 for collecting the cleaned debris. The cleaning head also has the aforementioned open cleaning channel.

[0056] Compared to existing technologies, in this application, the open cleaning channel can promptly release the gas pressure in the clean water mixed with gas sprayed from the cleaner's nozzle, thereby further alleviating the uneven water flow of the cleaner and further reducing noise.

[0057] Figure 2 The diagram shows the specific structure of the cleaning head of the cleaner of the present invention after the cleaning brush assembly and dustbin have been removed.

[0058] In some embodiments, such as Figure 2 As shown, the cleaning head housing 1 includes a left side plate 12, a right side plate 11 for holding the cleaning roller 2, and a housing body 10 connecting the left side plate and the right side plate. The left side plate 12 has a mezzanine with an opening at the top. One end of the mezzanine (not shown in the figure) is connected to one end of the "G"-shaped cleaning groove (the cleaning groove is located in...). Figure 4 The cross-section shows a "G" shape. The sewage outlet of the cleaning tank is also the sewage inlet of the interlayer (not shown in the attached diagram). The other end of the interlayer (not shown in the attached diagram) connects to the transfer chamber 13. The sewage outlet at the other end of the interlayer (not shown in the attached diagram) is also the sewage inlet of the transfer chamber 13 (not shown in the attached diagram). The interlayer with the sewage inlet and outlet perfectly encloses the sewage channel 120. The top opening of the interlayer, which is also the top opening of the sewage channel, is covered with a sewage channel cover plate 121. The top opening of the interlayer also has a recessed part (not shown in the attached diagram) to facilitate the user to pry open the sewage channel cover plate 121 by hand. Multiple cleaning tank openings 101 are provided above the top of the housing body 10, directly opposite the "G"-shaped cleaning tank. The cleaning tank flip cover 15 can seal and cover the cleaning tank openings 101 from the top. Figure 3As shown, the right side plate 11 is also provided with a sandwich layer, the outermost layer of which is pasted with a right side plate panel (not shown in the drawing), and the bottom plate of the sandwich layer is provided with a clean water channel cover plate (not shown in the drawing) which can be maintained only from the right side, and the clean water channel cover plate seals the clean water channel 110 on the bottom plate of the sandwich layer. Below the clean water channel 110 on the bottom plate of the sandwich layer, there is also a wiring groove (not shown in the drawing) for the power supply line of the cleaning brush assembly 6, and the bottom plate of the sandwich layer is also pasted with a right side plate panel (not shown in the drawing), which further covers the clean water channel 110, the wiring groove and the reinforcing ribs, and further beautifies the right side plate.

[0059] Figure 3 The arrangement and connection of the water pump and related water flow passage pipes and exhaust passage pipes built in the part of the machine body and the cleaning head after the right side plate panel of the cleaning head of the cleaner of the present application is removed are shown.

[0060] In some embodiments, as shown, Figure 3 As shown, the cleaning head housing 1 is also provided with a cleaning brush assembly 6 and a garbage box 7 which can be taken out from the top. The cleaner machine body and the cleaning head are hinged, and the waterway pipes and airway pipes arranged in the cleaning head extend out from the hinge joint to connect to other components of the cleaner machine body. The lower right side of the cleaner machine body near the hinge joint is provided with a clean water pump 8, the water inlet of which is connected with a water tank clean water outlet pipe 81, and the water outlet of which is connected with a water pump clean water outlet pipe 82 which communicates with the aforementioned clean water channel 110. The power source of the sewage passage of the cleaner is taken from a sewage pump which provides a continuous negative pressure to the sewage passage, and the working mode of the sewage pump is to continuously suck out air so that the suction port of the sewage pump can continuously provide a negative pressure to the sewage passage, thereby relying on the negative pressure to continuously suck the sewage from the aforementioned cleaning tank into the sewage chamber (not shown in the drawing) of the water tank (not shown in the drawing). The lower left side of the cleaner machine body near the hinge joint is provided with a sewage pump 9, the suction port of which is connected with a water tank air outlet pipe 92, and the air outlet of which is connected with a sewage pump exhaust pipe 93 which communicates with the aforementioned clean water channel 110. Because the clean water pump 8 of the cleaner works intermittently, the space of the aforementioned cleaning tank is also large enough, and the air sucked out by the sewage pump 9 will not affect the actual clean water flow when it is sent into the clean water channel 110, and the air sent into the aforementioned cleaning tank will be absorbed by the pores on the surface of the cleaning roller 2 on one hand and will be discharged out of the cleaning head along the pressure relief channel on the other hand.

[0061] In some embodiments, the working mode of the sewage pump is to continuously suck sewage and discharge sewage to provide power to the sewage passage, such as a peristaltic pump, a diaphragm pump, a sliding vane pump or a plunger pump, thereby relying on the sewage pump to continuously suck the sewage from the aforementioned cleaning tank into the sewage chamber (not shown in the drawing) of the water tank (not shown in the drawing).

[0064] In some embodiments, as Figure 4 、 Figure 5 、 Figure 6 The left side plate 12 includes a left side plate bottom plate and a left side plate cover plate, and the left side plate bottom plate is further provided with reinforcing ribs (not shown in the figure) arranged in the longitudinal and transverse directions. The upper part of the portion of the left side plate 12 framed in the cleaning tank is provided with a cleaning tank exhaust hole 16, and the cleaning tank exhaust hole 16 extends to the transfer bin 13 along the exhaust groove (not shown in the figure) formed in the right side plate bottom plate after passing through the right side plate bottom plate. The exhaust groove is provided with a cleaning tank exhaust pipe 132 connecting the cleaning tank exhaust hole 16 and the transfer bin 13. The upper part of the transfer bin 13 is further provided with a transfer bin exhaust pipe 131 connecting the upper part of the transfer bin and the surface of the cleaning roller 2. The transfer bin exhaust pipe 131 extends from the upper part of the transfer bin 13, bypasses the aforementioned cleaning brush assembly 6 and the garbage box 7, and extends into the arc-shaped groove (not shown in the figure) in the lower part of the bottom plate of the left side plate 12 from the bottom of the cleaning head shell body, as Figure 8 shown in the figure, finally close to one end of the shovel strip 5 to discharge air pressure to the surface of the cleaning roller 2. The upper part of the bottom plate of the left side plate 12 is further provided with a detachable sewage channel maintenance plate 122 near the transfer bin 13. After the sewage channel maintenance plate 122 is removed, the transfer bin water inlet 133 at the junction of the sewage channel and the transfer bin 13 can be cleaned and maintained, and the part of the sewage channel 120 that cannot be cleaned by only opening the sewage channel cover plate 121 can also be cleaned and maintained. The outermost layer of the left side plate is covered with a left side plate panel (not shown in the figure), which directly covers the sewage channel maintenance plate 122, the reinforcing ribs arranged in the longitudinal and transverse directions, and the arc-shaped groove in which part of the transfer bin exhaust pipe 131 is arranged, further beautifying the left side plate.

Figure 8 For the cleaner of the invention, the cleaning head is aligned with the view, showing the open cleaning channel of the application, the pressure relief channel from the cleaning tank, the starting position of the pressure relief channel. Figure 7 、 Figure 8The arrangement and connection of the cleaning head, the water pump built in the part of the machine body, the transfer bin, and the related water flow passage pipes and exhaust passage pipes are shown.

[0066] In some embodiments, as shown in Figure 7 、 Figure 8 The end opening of the sewage channel 120 (not marked in the figure) is connected to the transfer bin water inlet 133 of the transfer bin 13 (since the sewage channel 120 is hidden, the connection is not shown in the figure). Figure 7 The shell body 10 is hidden to clearly express the connection of the related pipes of the transfer bin 13 and other water pipes and air pipes, combined with Figure 2 、 Figure 3As per the aforementioned technical solution, the end of the sewage channel 120 must be connected to the transfer chamber 13. The transfer chamber is covered inside the housing body 10 and has a pipe connector (not shown in the attached figure) at its top. One end of the transfer chamber exhaust pipe 131 is connected to this pipe connector, and the other end of the transfer chamber exhaust pipe 131 bypasses the aforementioned cleaning brush assembly 6 and the garbage box 7, and extends back into the arc-shaped groove (not shown in the attached figure) at the bottom of the left side plate 12. The air pressure released from the cleaning tank is collected in 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 located on the lower left side of the cleaner body near the hinge joint. The sewage pump's suction port is connected to a water tank vent pipe 92, and the sewage pump's vent port is connected to a sewage pump exhaust pipe 93. The sewage pump exhaust pipe 93 is connected to the aforementioned clean water channel 110 via a forked tee 83. One of the two branch interfaces of the forked tee 83 is connected to the sewage pump exhaust pipe 93, and the other is connected to the clean water outlet pipe 82 of the water pump. The converging port of the forked tee 83 is connected to the cleaning tank water inlet pipe 84, which is connected to the aforementioned clean water channel 110. Because the cleaner's clean water pump 8 operates 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. The air sent into the aforementioned cleaning tank is absorbed by the pores on the surface of the cleaning roller 2 and is also discharged outside the cleaning head through the pressure relief channel. The transfer chamber 13 is equipped with a filter device (not shown in the attached diagram). A pipe connector (not shown in the attached diagram) is also located at the bottom of the transfer chamber 13. One end of the sewage pump pipe 91 is connected to this pipe connector, and the other end is connected to the sewage inlet of the water tank (not shown in the attached diagram). When the sewage pump 9 is working, air is discharged from its outlet. The discharged air flows sequentially through the sewage pump exhaust pipe 93, the forked tee 83, the cleaning tank water inlet pipe 84, and the clean water channel 110, finally entering the cleaning tank. Some of the air enters the pores on the surface of the cleaning roller 2 due to the flushing force of the water, while the remaining air exits the cleaning tank from the cleaning tank exhaust hole 16 and flows sequentially through the cleaning tank exhaust pipe 132, the transfer chamber 13, and the transfer chamber exhaust pipe 131. Finally, at the end of the transfer chamber exhaust pipe 131 closest to the shovel 5, the air pressure is released onto the surface of the cleaning roller 2. The sewage pump's suction port draws air from the sewage chamber of the water tank. After the air is expelled, the sewage, filtered through the transfer compartment, is continuously drawn into the sewage chamber of the water tank via the sewage suction pipe 91. Figure 8 As shown, after the main body 10 of the shell is hidden, the sewage channel maintenance plate 122 on the left side plate 12 is very close to the inlet 133 of the transfer chamber. In fact, the end of the sewage channel 120 must be connected to the transfer chamber 13 through the inlet 133 of the transfer chamber.

[0067] In some embodiments, such as Figure 2 , Figure 3 ,Figure 7 As shown, the cross-sectional width and height of the dirty water channel 120 are both greater than the cross-sectional width and height of the clean water channel 110. Since the dirty water pump exhaust pipe 93 and the clean water pump outlet pipe 82 converge into the cleaning tank water inlet pipe 84 through the forked tee joint 83, intermittent flow of clean water in the clean water channel will inevitably mix a certain amount of air into the cleaning tank water inlet pipe 84. Therefore, the design that the cross-sectional width and height of the dirty water channel 120 are both greater than the cross-sectional width and height of the clean water channel 110 is beneficial to the situation that the surface of the cleaning roller 2 in the cleaning tank cannot timely absorb the mixed air, and the excess air continues to flow along the dirty water channel to the transfer bin.

[0068] In some embodiments, as shown in Figure 2 , Figure 3 , Figure 4 , Figure 7 As shown, the open cleaning space further comprises a water tank cover 15 which can be detached from the top. Although the transfer bin 13 has a certain filtering and containing capacity for fine particulate solid waste, some fine particulate waste that passes through the filter through holes (not shown in the figure) will inevitably be deposited on the side of the extension part of the wringing strip 3 away from the cleaning roller 2 when the extension part of the wringing strip 3 is uniformly distributed with a plurality of filter through holes (not shown in the figure) on the surface of the cleaning roller 2. When the fine particulate waste is deposited to a certain extent, the filtering efficiency of the extension part of the wringing strip 3 will be reduced, thereby affecting the flow rate of the mixed water in the cleaning tank and further affecting the cleaning efficiency of the cleaner. At this time, the water tank cover 15 is opened from the top of the cleaner shell body 10, and the wringing strip can be easily cleaned. After cleaning, the cleaning capacity of the cleaner can be quickly restored.

[0069] In the second aspect, as shown in Figure 2 - Figure 8 The present application further provides a cleaner, which comprises a cleaning head provided with a shell, a cleaning roller arranged in the shell, a cleaning brush for cleaning the surface of the cleaning roller, and a garbage box for collecting the cleaned garbage. The cleaning head has the aforementioned open cleaning space. The embodiments of the cleaner have the same details as the aforementioned open cleaning space, and thus will not be described here.
