Description

[0001] This application is a divisional application of Chinese Patent Application No. 202310446943.6 entitled "An Open Cleaning Channel and a Cleaner with an Open Cleaning Channel", the contents of which are incorporated herein by reference. Technical Field

[0002] This invention relates to the field of cleaning equipment technology, and more particularly to an open cleaning channel and cleaner. Background Technology

[0003] Early floor cleaning tools used by people included brooms, mops, and floor scrubbers, which relied primarily on manual operation. With technological advancements, the demands for floor cleaning tools gradually increased, leading to the emergence of vacuum cleaners. These electric vacuums use negative pressure to suck up debris and dust from the floor. Classified by cleaning methods and the flow path of small and large debris, this type of technology is generally categorized as air-dust circulation technology. However, due to the limitations of its working principle, vacuum cleaners cannot clean some firmly adhered debris and stains. Therefore, a new type of floor scrubber, the "water-dust circulation" model, has emerged. This model uses a motor to drive a cleaning drum, typically made of sponge, to wipe the floor. The floor cleaner also includes a water supply system and a water tank to clean the drum, achieving a thorough cleaning of the floor. To clean the drum, a closed cleaning space connected to the water supply system is usually set up to clean specific sections of the drum, providing clean water for rinsing before the wastewater is pumped away.

[0004] Chinese patent CN212591943U discloses a self-cleaning mop, including a housing; a cleaning module comprising a dustbin, roller, shovel, water-pressing baffle, and scraper assembly respectively mounted on the housing; the shovel has an arc-shaped working surface, one end of which contacts the ground during operation, and the other end is located above the dustbin; a dust channel is formed between the arc-shaped working surface and the outer circumference of the roller; one end of the water-pressing baffle interferes with the sponge layer of the roller; the scraper assembly includes a friction end and a drainage end, which interfere with the sponge layer of the roller respectively; the roller, water-pressing baffle, scraper assembly, and housing together form a water tank, and the housing is provided with a water tank inlet and a water tank outlet; a water circulation module including a water tank mounted on the housing; the water tank includes a wastewater box, a filter box, and a purified water box, the wastewater box being connected to the water tank outlet and the filter box respectively, and the purified water box being connected to the water tank inlet and the filter box respectively. Paragraphs 50-53 of the specification disclose as follows. Figure 3As shown, water tank A is formed by a roller, a pressure baffle, a scraper assembly, and a housing. The housing has a water tank inlet and a water tank outlet. Clean water and / or purified water enter water tank A through the water tank inlet, and wastewater flows out of water tank A through the water tank outlet. The water tank inlet and outlet can be located at opposite ends of the water tank, with the water tank inlet on the right and the water tank outlet on the left. Clean water or purified water enters through the inlet, and wastewater from cleaning the roller flows out through the water tank outlet. The flow of water, with one end inlet and the other outlet, creates a dynamic water flow, thus cleaning the roller. Sticky debris adhering to the sponge layer of the roller is released from the sponge layer and enters water tank A under the action of water. The top of the scraper assembly can be inclined, with one end of the water tank inlet higher than the end of the outlet. In this case, the water flows in water tank A by its own weight. The inlet of the water tank can be positioned in the same place as the outlet. In this case, a reliable power unit will draw water from the outlet out of the water tank A. Inlets can be installed at both ends of the water tank A, allowing water to flow from both ends towards the middle of the tank A. A water nozzle can be installed on the casing, located at the upper middle part of the water tank A and connected to the sewage pipe. Under the action of the power unit, sewage is drawn from the water tank A through the water nozzle and enters the sewage pipe. Alternatively, clean water or purified water can be sprayed from the upper end of the water tank A into the tank A. In this case, at least one row of spray nozzles is arranged on the upper casing. Clean water or purified water is sprayed into the water tank A from the spray nozzles, cleaning the rollers, and then drawn away from the water tank A by its own weight or the action of the power unit.

[0005] Chinese patent CN114680747A discloses a cleaning head and cleaning tool. The cleaning head includes a housing; a first roller disposed within the housing for cleaning debris; a second roller disposed behind the first roller in the direction of rotation, rotating counterclockwise to clean the first roller; and a transfer filter chamber disposed on the housing, collecting and filtering wastewater generated by the first roller through a water tank on the housing. By setting a brush roller behind the sponge roller, the sponge roller can be cleaned in a timely manner, keeping it clean at all times and ensuring cleaning effectiveness. By setting a transfer filter chamber in the cleaning head, wastewater generated after self-cleaning is filtered, ensuring the self-cleaning effect of the cleaning head. In addition, water-dust exchange technology allows the water in the cleaning tool to circulate multiple times, achieving self-cleaning of the sponge roller, and combining sweeping, mopping, and washing, especially providing excellent cleaning effect for extremely difficult-to-handle sticky debris.

[0006] In existing water-dust circulation cleaners, a trough-shaped cleaning chamber is used. One end of the chamber is a clean water inlet, and the other end is a wastewater return outlet after rinsing the sponge roller. Alternatively, both ends of the chamber have clean water inlets, with the wastewater return outlet at the lower center. Or, both ends have wastewater return outlets at the lower center, with a clean water inlet at the higher center. The entire trough-shaped cleaning chamber lacks other ventilation holes. This causes the clean water nozzle to spray water mixed with air when the user manually moves the cleaning head. Because the cleaning chamber is closed, the wastewater return outlet will eventually draw the air sprayed from the nozzle back into the wastewater passage, reducing the wastewater return efficiency and the working efficiency of the air pump that draws in wastewater. The spraying of water mixed with air leads to uneven water distribution within the cleaning chamber, resulting in uneven water wetting of the sponge roller. Since the sponge roller rotates at a high speed, the wastewater squeezed out by the squeezing strip after one rotation will also be uneven. When the water spray nozzle contains air, it often generates a large number of bubbles in the water flow. As the water washes over the surface of the sponge roller, the large bubbles will shrink into smaller bubbles, and some bubbles will burst, producing some noise. Uneven water flow on the sponge roller will also produce some noise, and the air pump sucking up wastewater mixed with air will also produce noise.

[0007] To solve the above problems, it is necessary to find a solution that can release the gas pressure in the clear water mixed with gas sprayed from the nozzle in a timely manner, so as to further alleviate the uneven water flow and further reduce noise. Summary of the Invention

[0008] The main technical problem solved by this invention is to provide an open cleaning channel that can release the gas pressure in the clean water mixed with gas sprayed from the nozzle of the cleaner in a timely manner, so as to further alleviate the uneven flow of clean water in the cleaner and further reduce noise.

[0009] In a first aspect, the present invention provides an open cleaning channel disposed on a cleaning head housing equipped with a cleaning roller, and inverted on the upper part of the cleaning roller. The cleaning head housing includes a left side plate, a right side plate for holding the cleaning roller, and a housing body connecting the left side plate and the right side plate. The cleaning channel includes a "G"-shaped 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 pressure relief channel is led out from the cleaning tank and connected to a transfer chamber through a pipeline, and then continues to release air pressure from the transfer chamber to the outside of the cleaning head housing through a pipeline.

[0010] In one or more embodiments, a transfer chamber inlet is provided at the junction of the sewage channel and the transfer chamber.

[0011] In one or more embodiments, a pressure relief hole is provided at the upper part of one end of the cleaning tank, which is connected to a pressure relief channel.

[0013] In one or more embodiments, the left side plate is provided with a first interlayer with an opening at the top. One end of the first interlayer is connected to one end of the cleaning tank, and the sewage outlet of the cleaning tank is the sewage inlet of the interlayer. The other end of the first interlayer is connected to the transfer chamber, and the sewage outlet at the other end of the first interlayer is the sewage inlet of the transfer chamber. The first interlayer with the sewage inlet and sewage outlet encloses a sewage channel.

[0014] In one or more embodiments, the left side panel includes a left side panel bottom plate, the right side panel includes a right side panel bottom plate, the outermost layer of the left side panel is covered with a left side panel, and the inner side of the first interlayer is the left side panel bottom plate.

[0015] In one or more embodiments, a cleaning tank vent is provided at the upper part of the portion of the left side plate that is framed into the cleaning tank. After passing through the bottom plate of the right side plate, the cleaning tank vent extends along the vent groove provided on the bottom plate of the right side plate to the transfer chamber. A cleaning tank vent pipe connecting the cleaning tank vent and the transfer chamber is provided in the vent groove.

[0016] In one or more embodiments, the upper part of the transfer chamber is further provided with a transfer chamber exhaust pipe that connects the upper part of the transfer chamber and the surface of the cleaning roller. The transfer chamber exhaust pipe extends out from the upper part of the transfer chamber, bypasses the cleaning brush assembly and dust box installed in the cleaning head housing, and extends back into the arc-shaped groove at the bottom of the left side plate from the bottom of the housing body.

[0017] In one or more embodiments, the top opening of the first interlayer is covered with a sewage channel cover, and the top opening of the first interlayer is also provided with a recessed portion for easy removal of the sewage channel cover.

[0018] In one or more embodiments, a detachable sewage channel maintenance plate is provided on the upper part of the bottom plate of the left side plate near the transfer chamber. After removing the sewage channel maintenance plate, the inlet of the transfer chamber at the junction of the sewage channel and the transfer chamber can be cleaned and maintained, and the sewage channel that cannot be cleaned by simply opening the sewage channel cover can also be cleaned and maintained.

[0019] In one or more embodiments, the end opening of the sewage channel and the inlet of the transfer chamber are connected in a continuous manner.

[0020] In one or more embodiments, the transfer chamber is covered by a pipe joint on the top inside the housing body. One end of the transfer chamber exhaust pipe is connected to the pipe joint. The air pressure released from the cleaning tank is collected in the transfer chamber along the cleaning tank exhaust pipe. Finally, the air pressure in the transfer chamber can be released to the surface of the cleaning roller through the transfer chamber exhaust pipe.

[0021] In one or more embodiments, the right side plate is provided with a second interlayer, the outermost layer of the second interlayer on the right side is covered with a right side plate panel, and the bottom plate of the second interlayer is provided with a clean water channel cover that can only be maintained from the right side. The clean water channel cover seals and surrounds the clean water channel on the bottom plate of the second interlayer.

[0022] In one or more embodiments, a wiring groove for routing power cables for the cleaning brush assembly is provided below the water channel of the second interlayer bottom plate. The second interlayer bottom plate is also evenly distributed with alternating warp and weft reinforcing ribs. A right side panel is also attached to the second interlayer bottom plate to further cover the water channel, wiring groove and reinforcing ribs.

[0023] In one or more embodiments, the pressure relief channel includes an exhaust pipe located on the left side plate, one end of which is connected to a cleaning tank, and the other end of which is connected to a transfer chamber located on the cleaning head housing that is connected to the outside atmosphere.

[0024] In one or more embodiments, the transfer chamber is connected to a pressure relief pipe that is open to the atmosphere, and the other end of the pressure relief pipe is connected to the surface of the cleaning roller.

[0025] In one or more embodiments, the sewage channel is connected to the upper part of the transfer chamber, which is equipped with a filtration device. The sewage channel also includes a pumping pipe with one end located at the bottom of the transfer chamber for pumping out the filtered sewage, and the other end of the pumping pipe is connected to a sewage pump.

[0026] In one or more embodiments, the suction port of the sewage pump is connected to the air outlet pipe of the water tank, the air outlet of the sewage pump is connected to the exhaust pipe of the sewage pump, the exhaust pipe of the sewage pump is connected to the clean water channel, and the air drawn out by the sewage pump is sent into the cleaning tank. The drawn-out air is absorbed by the pores on the surface of the cleaning roller and is also discharged to the outside of the cleaning head through the pressure relief channel.

[0027] In one or more embodiments, the clean water channel further includes a clean water pipe connected at one end to the clean water channel, and the other end of the clean water pipe connected to the converging port of a forked tee, with one branch interface of the forked tee connected to the clean water pump via a water supply pipe.

[0028] In one or more embodiments, the open cleaning channel also includes a detachable flap that can be removed from the top, which facilitates cleaning of the cleaning tank after the flap is removed.

[0029] In a second aspect, the present invention also provides a cleaner, including a cleaning head, the cleaning head having a housing and a cleaning roller disposed in the housing, a cleaning brush assembly for cleaning the surface of the cleaning roller, and a garbage box for collecting the cleaned garbage, the cleaning head having an open cleaning channel as described in the first aspect.

[0030] In one or more embodiments, the cleaner further includes a cleaner body, which houses a water pump and related water flow path pipes and exhaust passage pipes. The cleaner body is also equipped with a body panel that can cover the water pump and related water flow path pipes and exhaust passage pipes.

[0031] In one or more embodiments, the cleaner body and the cleaning head are hinged, the cleaning brush and the dustbin can be removed from the top of the cleaning head housing, and the water pipes and air pipes arranged inside the cleaning head extend out from the hinge joint and connect to other parts of the cleaner body.

[0032] In one or more embodiments, a clean water pump is provided on the lower right side of the cleaner body near the hinge joint. The inlet of the clean water pump is connected to a clean water outlet pipe from the water tank, and the outlet of the clean water pump is connected to a clean water outlet pipe from the water pump, which is connected to a clean water channel.

[0033] In one or more embodiments, a sewage pump is provided on the lower left side of the cleaner body near the hinge joint. The suction port of the sewage pump is connected to the air outlet pipe of the water tank, and the air outlet of the sewage pump is connected to the exhaust pipe of the sewage pump. The exhaust pipe of the sewage pump is connected to the clean water channel. The air drawn out by the sewage pump is sent into the cleaning tank. The drawn-out air is absorbed by the pores on the surface of the cleaning roller and is also discharged to the outside of the cleaning head through the pressure relief channel.

[0034] This invention provides an open cleaning channel. An exhaust pipe extends from the upper part of the cleaning tank to a transfer filter chamber that maintains communication with the outside atmosphere. Furthermore, exhaust pipes extend from the upper sidewalls at both ends of the cleaning channel to the transfer filter chamber, ensuring that the gas pressure in the cleaning channel remains constant at the same level as the outside atmosphere. Because the exhaust vents of the cleaning tank are located in the upper space of the cleaning tank, the water level during normal use will not exceed the height of the exhaust vents. Even if a small amount of water is mixed in during the exhaust process, it will not significantly affect the overall water volume. The transfer chamber is a node in the wastewater return path. Having one or more exhaust channels to the transfer chamber ensures that the pressure in the cleaning channel remains constantly connected to the outside atmosphere and prevents the loss of the pressure regulation function of the exhaust channels due to blockage of individual exhaust channels. This invention also provides a cleaner, including a cleaning head. The cleaning head has a housing, a cleaning roller disposed on the housing, a cleaning brush for cleaning the surface of the cleaning roller, and a waste collection box for collecting the cleaned debris. The cleaning head also has the aforementioned open cleaning channel.

[0035] Beneficial effects of this invention:

[0036] 1. An exhaust port has been added to the upper part of the cleaning tank in the cleaner. This allows the air mixed with the clean water sprayed from the clean water nozzle, which does not provide any additional benefit to the cleaning roller in wiping the surface to be cleaned, to be further discharged to other areas outside the entire water flow loop. The sewage return port can draw a larger proportion of sewage into the sewage return passage, improving the sewage return efficiency and the working efficiency of the air pump that draws sewage.

[0037] 2. Water sprayed with air can cause uneven water distribution in the cleaning chamber. However, the trapped air is diverted by the exhaust passage, which can improve the uniformity of water distribution on the sponge roller. No more air will be forced into the pores of the sponge layer of the sponge roller along with the water. The sponge roller rotates at a high speed, and the wastewater squeezed out by the squeezing strip after one rotation will naturally be more even.

[0038] 3. When the water spray nozzle contains air, it often generates a large number of bubbles in the water flow. As the water washes over the surface of the sponge roller, the large bubbles will decrease into smaller bubbles, and some bubbles will burst, producing some noise. After the air trapped in the water is diverted by the exhaust channel, the uniformity of water flow to the sponge roller can be improved. No more air will be forcibly injected into the pores of the sponge layer of the sponge roller, which can reduce the noise generated by the bursting of bubbles. Attached Figure Description

[0057] The preferred embodiments of the present invention will be described below with reference to the accompanying drawings. It should be understood that the preferred embodiments described herein are for illustration and explanation only and are not intended to limit the present invention.

[0058] In existing technologies, such as Figure 1 As shown, the squeezing strip 3 is installed on the housing 10 of the cleaning head 1 of the cleaner. The squeezing strip 3 squeezes the surface of the cleaning roller 2. The squeezing strip 3 is installed on a vertical cleaning roller guard plate (not shown in the figure) on one end face of the inner side of the housing 10. A vertical plate (not shown in the figure) is provided on the opposite side of the guard plate. The water-collecting strip 4 is installed on the vertical plate. Parts of the surfaces of the squeezing strip 3, the cleaning roller 2, the water-collecting strip, the vertical plate, and the cleaning roller guard plate together form a cleaning groove (not shown in the figure) that allows clean water to continuously rinse the upper surface of the cleaning roller. A detachable flip cover 15 is also provided on the top of the cleaning groove. The cleaning groove is "G" shaped. The hook of the "G" shape is exactly the water-dividing hook of the squeezing strip. The opening of the "G" shape is directly opposite the surface of the cleaning roller 2 to be rinsed and the water-collecting strip 4.

[0059] Firstly, such as 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.

[0060] 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.

[0061] 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.

[0062] 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 sandwich panel with an opening at the top. One end of the sandwich panel (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 of the interlayer is "G" shaped. 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, and 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 portion (not shown in the attached diagram) to facilitate the user to pry open the sewage channel cover plate 121. 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 flap 15 can seal and cover the cleaning tank openings 101 from the top. Figure 3 As shown, the right side panel 11 also has a mezzanine. The outermost layer of this mezzanine on the right side is covered with a right side panel (not shown in the attached figure). The bottom plate of this mezzanine has a water channel cover plate (not shown in the attached figure) that can only be maintained from the right side. The water channel cover plate seals and surrounds the water channel 110 on the bottom plate of the mezzanine. Below the water channel 110 on the bottom plate of the mezzanine, there is also a wiring groove (not shown in the attached figure) for running the power cord of the cleaning brush assembly 6. The bottom plate of the mezzanine also has evenly distributed warp and weft reinforcing ribs (not shown in the attached figure). The bottom plate of the mezzanine is also covered with a right side panel (not shown in the attached figure), further covering the water channel 110, the wiring groove and the reinforcing ribs, further improving the appearance of the right side panel.

[0063] Figure 3 The diagram shows the cleaning head after the right side panel of the cleaner of the present invention has been removed, and the arrangement and connection of the water pump and related water flow path pipes and exhaust passage pipes in part of the body after the body panel has been removed.

[0064] In some embodiments, such as Figure 3As shown, the cleaning head housing 1 also includes a cleaning brush assembly 6 and a dustbin 7 that can be removed from the top. The cleaner body and the cleaning head are hinged together. Water and air pipes arranged inside the cleaning head extend from the hinge joint to other parts of the cleaner body. A clean water pump 8 is located on the lower right side of the cleaner body near the hinge joint. The inlet of the clean water pump is connected to a clean water outlet pipe 81 from the water tank, and the outlet of the clean water pump is connected to a clean water outlet pipe 82 from the water pump. The clean water outlet pipe 82 connects to the aforementioned clean water channel 110. The power source for the wastewater passage of the cleaner is a wastewater pump that provides continuous negative pressure to the wastewater pipeline. The wastewater pump operates by continuously drawing air outward so that the suction port of the wastewater pump can continuously provide negative pressure to the wastewater passage, thereby relying on the negative pressure to continuously draw wastewater from the aforementioned cleaning tank into the wastewater chamber (not shown in the attached figure) of the water tank (not shown in the attached figure). A wastewater pump 9 is located on the lower left side of the cleaner body near the hinge joint. The suction port of the wastewater pump is connected to the air outlet pipe 92 of the water tank, and the air outlet of the wastewater pump is connected to the exhaust pipe 93 of the wastewater pump. The exhaust pipe 93 of the wastewater pump is connected to the aforementioned clean water channel 110. Because the clean water pump 8 of the cleaner operates intermittently, and the space of the aforementioned cleaning tank is large enough, the air extracted by the wastewater pump 9 is sent into the clean water channel 110 without affecting the actual clean water flow. 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.

[0065] In some embodiments, the sewage pump operates as a peristaltic pump, diaphragm pump, vane pump, or plunger pump that continuously pumps and discharges sewage, thereby continuously pumping sewage from the aforementioned cleaning tank into the sewage chamber (not shown in the attached figure) of the water tank (not shown in the attached figure).

[0066] Figure 4 This is a planar view of the cleaning head of the cleaner of the present invention, showing the starting position of the pressure relief channel of the open cleaning channel of the present application leading out of the cleaning tank.

[0067] Figure 5 This is a perspective view of the cleaning head of the cleaner of the present invention after the left side panel and the bottom plate of the housing body have been removed. Figure 6 for Figure 5 Enlarged view of a portion of point A in the middle. Figure 5 , Figure 6 The pressure relief channel is shown to extend from the cleaning tank through a pipeline to the transfer chamber, and then the air pressure is released from the transfer chamber to the outside of the cleaning head through a pipeline.

[0068] In some embodiments, such as Figure 4 , Figure 5 , Figure 6As shown, the left side plate 12 includes a left side plate bottom plate and a left side plate cover plate. The left side plate bottom plate is also evenly distributed with alternating warp and weft reinforcing ribs (not shown in the attached figure). A cleaning tank vent 16 is provided at the upper part of the portion of the left side plate 12 that is framed within the cleaning tank. After passing through the right side plate bottom plate, the cleaning tank vent 16 extends along the vent groove (not shown in the attached figure) on the right side plate bottom plate to the transfer chamber 13. A cleaning tank vent pipe 132 connecting the cleaning tank vent 16 and the transfer chamber 13 is provided within the vent groove. A transfer chamber vent pipe 131 is also provided at the upper part of the transfer chamber 13, connecting the upper part of the transfer chamber and the surface of the cleaning roller 2. The transfer chamber vent pipe 131 extends from the upper part of the transfer chamber 13, bypasses the aforementioned cleaning brush assembly 6 and dust box 7, and extends back into the arc-shaped groove (not shown in the attached figure) at the lower part of the bottom plate of the left side plate 12, as shown in the attached figure. Figure 8 The air pressure is released to the surface of the cleaning roller 2 at the end that is closest to the shovel 5. A removable sewage channel maintenance plate 122 is also provided on the upper part of the bottom plate of the left side plate 12 near the transfer chamber 13. After removing the sewage channel maintenance plate 122, the transfer chamber inlet 133 at the junction of the sewage channel and the transfer chamber 13 can be cleaned and maintained, as can the portion of the sewage channel 120 that cannot be cleaned by simply opening the sewage channel cover plate 121. The outermost layer of the left side plate is covered with a left side plate panel (not shown in the attached diagram), which directly covers the sewage channel maintenance plate 122, the interlaced reinforcing ribs, and the arc-shaped groove for arranging part of the transfer chamber exhaust pipe 131, further enhancing the appearance of the left side plate.

[0069] Figure 7 This is a schematic diagram of the internal piping connection of the cleaning head of the cleaner device of the present invention, hidden behind the housing body. Figure 8 This is a schematic diagram showing the internal piping connections of the cleaning head of the cleaner device of the present invention, with only the bottom shell of the housing remaining. Figure 7 , Figure 8 The layout and connection of the cleaning head, part of the built-in water pump, transfer chamber, and related water flow path pipes and exhaust passage pipes are shown.

[0070] In some embodiments, such as Figure 7 , Figure 8 As shown, the end opening of the sewage channel 120 (not shown in the attached diagram) and the transfer chamber inlet 133 of the transfer chamber 13 are connected continuously (due to...). Figure 7 The shell body 10 is concealed to clearly illustrate the relevant pipelines and other water and air pipeline connections of the transfer chamber 13, 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 scouring 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.

[0071] In some embodiments, such as Figure 2 , Figure 3 , Figure 7 As shown, the cross-sectional width and height of the sewage channel 120 are both greater than those of the clear water channel 110. Since the sewage pump exhaust pipe 93 and the water pump outlet clear water pipe 82 converge into the cleaning tank water injection pipe 84 through the forked tee 83, the intermittent flow of clear water in the clear water channel will inevitably mix in a certain amount of air into the cleaning tank water injection pipe 84. This design, where the cross-sectional width and height of the sewage channel 120 are greater than those of the clear water channel 110, is beneficial because if the surface of the cleaning roller 2 in the cleaning tank cannot absorb all the mixed air in time, the excess air will continue to be discharged to the transfer chamber along the sewage channel.

[0072] In some embodiments, such as Figure 2 , Figure 3 , Figure 4 , Figure 7 As shown, the open cleaning space also includes a detachable water tank cover 15, which is detachable from the top. A detachable water tank cover 15 is also installed directly above the cleaning tank. Although the transfer chamber 13 has a certain capacity to filter and hold fine particulate solid waste, due to the multiple filter holes (not shown in the attached diagram) evenly distributed on the extension portion (not shown in the attached diagram) of the squeezing strip 3, which is close to the surface of the cleaning roller 2, some fine particulate waste that has passed through the filter holes will inevitably accumulate on the side of the extension portion away from the cleaning roller. When the fine particulate waste accumulates to a certain extent, it will reduce the filtration efficiency of the extension portion of the squeezing strip 3, thereby affecting the flow rate of the clean and dirty water mixture in the entire cleaning tank, and further affecting the cleaning efficiency of the cleaner. At this time, the squeezing strip can be easily cleaned by flipping open the water tank cover 15 from the top of the cleaner's housing 10, and the cleaning ability of the cleaner can be quickly restored after cleaning.

[0073] Secondly, such as Figure 2 - Figure 8 As shown, the present invention also provides a cleaner, including a cleaning head, which has a housing, a cleaning roller disposed on the housing, a cleaning brush for cleaning the surface of the cleaning roller, and a garbage box for collecting the cleaned debris. The cleaning head has the aforementioned open cleaning space. Other details of the embodiments of this cleaner are the same as those of the aforementioned open cleaning space embodiments, and will not be repeated here.

For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as the combination of these technical features does not contradict each other, it should be considered within the scope of this specification.
