[0003] This application relates to the field of cleaning equipment technology, and in particular to a host and a cleaning device. Background Technology

[0004] Cleaning robots (such as robotic vacuum cleaners) consist of a base, fan, waste tank, drive wheels, nozzle, and water tank. These components are mounted on the base. The drive wheels contact the ground, moving the base and consequently the fan, waste tank, nozzle, and water tank for cleaning. Existing cleaning equipment often has limited space for the waste tank, resulting in a small tank capacity. Summary of the Invention

[0005] The main objective of this application is to propose a host and cleaning device that aims to solve the problem of limited space for installing sludge storage tanks in existing cleaning devices.

[0006] To achieve the above objectives, the host computer proposed in this application is applied to a cleaning device, the cleaning device including a sludge storage tank, and the host computer includes:

[0007] The base has a mounting position for installing a sludge storage tank; and

[0008] A fan, battery, casters, and two drive wheels are mounted on the base. The fan, battery, and casters are located on the front side of the mounting position, and the two drive wheels are located on the left and right sides of the mounting position, respectively.

[0009] In one embodiment, the main unit further includes an air inlet, which is located at the mounting position, and the air inlet end is connected to the air inlet via a first pipe.

[0010] In one embodiment, the air inlet of the fan is oriented downwards, and the air inlet is positioned higher than the air inlet.

[0011] In one embodiment, the mounting position is further provided with a first exhaust port, which is connected to the air outlet of the fan via a second pipeline.

[0012] In one embodiment, the first exhaust vent is located between the left and right center lines of the main unit and one of the drive wheels.

[0013] In one embodiment, a fifth mounting cavity is formed between the fan and the battery.

[0014] In one embodiment, the host unit further includes a monitoring device located between the fan and the battery, and positioned on the front side of the mounting location.

[0015] In one embodiment, a portion of the monitoring element is located above the wind turbine and the battery;

[0016] And / or, the monitoring device is configured as a radar.

[0017] In one embodiment, the main unit further includes a collision plate, which is mounted on the base and located in front of the fan and the battery;

[0018] And / or, the casters are located on the left and right center lines of the host machine;

[0019] And / or, the two drive wheels are symmetrically arranged about the left and right center lines of the host.

[0020] This application also proposes a cleaning device, comprising: a main unit; and

[0021] The operating module includes a suction nozzle assembly and a water tank assembly installed on the first base; the suction nozzle assembly, the water tank assembly and the fan are horizontally arranged, and the suction nozzle of the suction nozzle assembly, the water tank assembly and the fan are arranged sequentially along the horizontal longitudinal direction of the main unit.

[0022] The technical solution of this application uses a fan, battery, casters, and two drive wheels arranged around the mounting position, so that the mounting position can form an independent space on the base. This independent space is used for the installation of the sludge storage tank. At the same time, the two drive wheels are respectively located on the left and right sides of the mounting position, and the fan, battery, and casters are all located on the front side of the mounting position. This arrangement can make the mounting position on the base as large as possible. When the mounting position is as large as possible, the structure of the sludge storage tank installed in the mounting position can also be as large as possible, thereby maximizing the capacity of the sludge storage tank and solving the problem of small sludge storage tank capacity in the prior art.

[0042] Cleaning robots (such as robotic vacuum cleaners) consist of a base, fan, waste tank, drive wheels, nozzle, and water tank. These components are mounted on the base, and the drive wheels contact the ground, moving the base and consequently the fan, waste tank, nozzle, and water tank for cleaning. Existing cleaning equipment often has limited space for the waste tank, resulting in a small capacity. This small capacity means the cleaning robot needs to empty the tank frequently after a short cleaning session, leading to shorter cleaning times and less effective cleaning.

[0043] This application proposes a host computer for use in cleaning equipment, the cleaning equipment including a sludge storage tank 10.

[0044] Please refer to Figures 2 and 3. In one embodiment of this application, the main unit includes a base 110, a fan 200, a battery 300, casters 400, and two drive wheels 500. The base 110 has a mounting position for installing a sludge storage tank 10. The fan 200, battery 300, casters 400, and two drive wheels 500 are all mounted on the base 110. The fan 200, battery 300, and casters 400 are located in front of the mounting position, and the two drive wheels 500 are located on the left side of the mounting position. On the right and both sides, the fan 200, battery 300, casters 400, and two drive wheels 500 are arranged around the mounting position, creating an independent space on the base 110 for the installation of the sludge tank 10. The two drive wheels 500 are positioned on the left and right sides of the mounting position, while the fan 200, battery 300, and casters 400 are located at the front. This arrangement avoids placing all components on the sides of the mounting position, which would result in a wider base 110. This layout also maximizes the size of the mounting position on the base 110, allowing for a larger structure for the sludge tank 10 and thus maximizing its capacity. This addresses the issue of small capacity in existing sludge tanks. It should be noted that the two drive wheels 500 and casters 400 provide three-point support, ensuring the base 110 is stably placed on the ground.

[0045] It should be noted that the two drive wheels 500 are symmetrically arranged about the left and right center lines of the main unit, and the omnidirectional wheels 400 are arranged about the left and right center lines of the main unit, which enables the main unit to move smoothly.

[0046] In one embodiment, to enable better communication between the blower 200 and the sludge storage tank 10, while ensuring that the blower 200 does not occupy the installation position (i.e., the installation position of the sludge storage tank 10), the main unit further includes an air inlet 600. The air inlet 600 is located at the installation position, and the air inlet end is connected to the air inlet 600 via a first pipe 610. It should be noted that in this embodiment, the blower 200 is located in front of the installation position. By setting the air inlet 600 at the installation position, and further, in some embodiments, the sludge storage tank 10 is provided with a structure so that when the sludge storage tank 10 is installed at the installation position, the interface in the sludge storage tank 10 can be connected to the air inlet 600. This enables communication between the blower 200 and the sludge storage tank 10. In this case, setting the air inlet 600 at the installation position significantly reduces the space occupied by the blower 200 compared to setting the blower 200 at the installation position. Furthermore, in some embodiments, depending on the height of the air inlet 600, when the sludge storage tank 10 is installed at the mounting position: if the air inlet 600 is set relatively high, it can be directly connected to the interface in the sludge storage tank 10; if the air inlet 600 is set relatively low, a third pipe is provided in the sludge storage tank 10 to connect the air inlet 600 and the interface. It should be noted that to ensure the sludge storage capacity of the sludge storage tank 10, the interface in the sludge storage tank 10 needs to be positioned relatively high. If the air inlet 600 is set relatively high, a third pipe is not needed in the sludge storage tank 10; if the air inlet 600 is set relatively low, a third pipe is needed in the sludge storage tank 10 to ensure the interface in the sludge storage tank 10 is at a relatively high position. If the interface in the sludge storage tank 10 is positioned too low, there will be a problem of the fan 200 sucking in sewage from the sludge storage tank 10. At the same time, setting the air inlet 600 at a relatively low position can also reduce the space occupied by the air inlet 600 at the installation location.

[0047] In one embodiment, the air inlet of the fan 200 is oriented downwards, and the air inlet 600 is positioned higher than the air inlet. Furthermore, the air inlet 600 and the air inlet are connected via a first pipe 610. It should be noted that when the fan 200 draws air through the air inlet, the moisture content of the gas is relatively high. This can cause water droplets to condense in the first pipe 610. By oriented the air inlet of the fan 200 downwards, the gas moves upwards as it enters the air inlet. In other words, under the influence of gravitational potential energy, the water droplets condensed in the first pipe 610 are less likely to move upwards and enter the fan 200, thus preventing excessive condensation and potential damage to the fan 200. Conversely, if the air inlet of the fan 200 were oriented upwards, the water droplets condensed in the first pipe 610 would enter the fan 200 through the air inlet, causing damage.

[0048] In one embodiment, referring to Figures 4 and 5, the mounting position is further provided with a first exhaust port 180. The first exhaust port 180 is connected to the air outlet of the fan 200 through a second pipe 710. It can be understood that the first exhaust port 180 is located in the mounting position, which, compared to being located at the bottom of the base 110, allows the base 110 to be relatively thin, thereby making the size of the main unit relatively small.

[0049] Furthermore, in one embodiment, referring to Figures 2 and 4, the first exhaust vent 180 is located between the left and right center lines of the main unit and one of the drive wheels. It can be understood that the first exhaust vent 180 is offset from the left and right center lines of the main unit. Thus, the second pipe 710 connecting the first exhaust vent 180 can make the area on one side of the mounting position located on the left and right center lines of the main unit bulge upward, thereby forming a trend where one side is relatively high and the other side is relatively low. It should be noted that when the sludge storage tank 10 is installed at the mounting position, after the sludge storage tank 10 is attached to the mounting position, the bottom of the sludge storage tank 10 can form a structure where one side is relatively high and the other side is relatively low (similar to a step). When the sludge storage tank 10 is in use, the sewage can be concentrated in the relatively low area. It can be understood that concentrating the sewage in one place can facilitate the discharge of sewage from the sludge storage tank 10. Furthermore, in some embodiments, a drain outlet can be provided in the relatively low area of ​​the sludge storage tank 10.

[0050] In one embodiment, referring to Figure 3, a fifth mounting cavity 190 is formed between the fan 200 and the battery 300. It should be noted that this fifth mounting cavity 190 can accommodate a first pipe 610 connecting the air inlet of the fan 200 to the air inlet 600, a drainage pipe connecting the sludge storage tank 10 (not shown in the figure), or other wiring structures on the main unit, such as the control motherboard. Furthermore, in some embodiments, the caster wheel 400 is positioned below the fifth mounting cavity 190, thus making the main unit structure more compact. It should be noted that since the fifth mounting cavity 190 is formed between the fan 200 and the battery 300, when the caster wheel 400 is positioned below the fifth mounting cavity 190, the fifth mounting cavity 190 can provide some clearance for the installation of the caster wheel 400.

[0051] In one embodiment, referring to Figures 1, 3, and 4, the main unit further includes a monitoring component 800 located between the fan 200 and the battery 300, and positioned at the front of the mounting location. The monitoring component 800 is used to detect obstacles in front of the main unit. In some embodiments, the monitoring component 800 can be installed in the fifth mounting cavity 190, which allows for a more compact main unit structure, better utilization of the front space of the mounting location, and reduced space occupation, ensuring a larger effective space for the sludge storage tank 10.

[0052] In one embodiment, referring to Figures 4 and 5, a portion of the structure of the monitoring element 800 is located above the fan 200 and the battery 300. Thus, to maximize the utilization of the structure of the fifth mounting cavity 190, when a motherboard or other structure is installed within the fifth mounting cavity 190, a portion of the monitoring element 800 can be located within the fifth mounting cavity 190, while another portion is located above the fan 200 and the battery 300, i.e., outside the fifth mounting cavity 190. In one embodiment, the monitoring element 800 is configured as a radar. In some embodiments, the monitoring element 800 can be configured as a camera and a sensor, using a combination of both to achieve monitoring. The sensor primarily measures distance, while the camera primarily acquires image information.

[0053] In one embodiment, referring to FIG1, the host also includes a collision plate 900, which is installed on the base 110 and located in front of the fan 200 and the battery 300. Thus, when the host moves forward, the collision plate 900 can provide better protection for the fan 200 and the battery 300.

[0054] In one embodiment, referring to FIG2, the casters 400 are arranged on the left and right center lines of the main unit, which enables the main unit to be more balanced when moving.

[0055] The mobile robot consists of a base, fan, waste tank, drive wheels, suction nozzle assembly, and water tank. These components are mounted on the base, and the drive wheels contact the ground, moving the base and consequently the fan, waste tank, suction nozzle assembly, and water tank for cleaning. Existing cleaning equipment arranges the waste tank, water tank, fan, and roller brush from top to bottom. This arrangement results in a relatively high cleaning device, making it difficult for the mobile robot to access areas with limited height (under tables, coffee tables, sofas, etc.) when cleaning carpets.

[0056] This application proposes a cleaning device.

[0057] Please refer to Figures 6, 7, and 8. In one embodiment of this application, the cleaning equipment includes a main unit 100 and an operating module 2001. The main unit 100 includes a first base 110, a fan 200 mounted on the first base 110, two drive wheels 500, and casters 400. The two drive wheels 500 are symmetrically arranged about the main unit 100, specifically about the horizontal longitudinal centerline of the main unit 100. The casters 400 and the two drive wheels 500 form a three-point support, enabling the main unit 100 to be stably placed on the ground. The drive wheels 500 drive the main unit 100 to move and turn.

[0058] The operating module 2001 includes a suction nozzle assembly 210 and a water tank assembly 220 installed on the first base 110. The suction nozzle assembly 210, the water tank assembly 220, and the blower 200 are horizontally arranged. The suction nozzle of the suction nozzle assembly 210, the water tank assembly 220, and the blower 200 are arranged sequentially along the horizontal longitudinal direction of the main unit 100. It should be noted that the water tank assembly 220 includes a clean water tank 221 and a sludge storage tank 222, wherein the blower 200 is connected to the sludge storage tank 222, and the suction nozzle assembly 210 is connected to the sludge storage tank 222. The operating module 2001 also includes a roller brush assembly 240, and the clean water tank 221 can feed water into the roller brush assembly 240. The roller brush assembly 240 washes the carpet by delivering clean water. After washing, the suction nozzle assembly 210 absorbs the wastewater on the carpet and it enters the wastewater storage tank 222. The roller brush assembly 240 includes a roller brush 20 and a drive motor 241 that drives the roller brush 20 to rotate. It should be noted that the clean water tank 221 delivers clean water to the roller brush assembly 240 by dripping or spraying. That is, the clean water tank 221 is equipped with a drip tube or nozzle. At this time, the roller brush assembly 240 is located below the clean water tank 221. The clean water tank 221 delivers clean water to the roller brush 20 in the roller brush assembly 240 through the drip tube or nozzle. At this time, the roller brush 20 is in a wet state during cleaning. Furthermore, in this embodiment, by arranging the suction nozzle of the suction nozzle assembly 210, the water tank assembly 220, and the fan 200 sequentially along the horizontal and vertical direction of the main unit 100, the problem of the main unit 100 being too tall can be avoided, thereby facilitating the cleaning equipment to clean carpets in areas with limited height, and thus solving the technical problems existing in the prior art.

[0059] In one embodiment, referring to Figures 7 and 9, the working module 2001 further includes a second base 230 and a roller brush assembly 240. The suction nozzle assembly 210, the water tank assembly 220, and the roller brush assembly 240 are mounted on the second base 230, and the second base 230 is detachably connected to the first base 110. It can be understood that since the roller brush assembly 240, the suction nozzle assembly 210, and the water tank assembly 220 are all mounted on the second base 230, the working module 2001 can be a separate module. Furthermore, the second base 230 is detachably connected to the first base 110; that is, by removing the second base 230 from the first base 110, the entire working module 2001 can be removed from the main unit 100, facilitating the replacement of the entire working module 2001.

[0060] In one embodiment, referring to Figures 6 and 8, the water tank assembly 220 includes a clean water tank 221 and a sludge storage tank 222. The clean water tank 221 is provided with a first mounting cavity 2211 and a second mounting cavity 2212. The first mounting cavity 2211 and the second mounting cavity 2212 are arranged back and forth along the horizontal longitudinal direction of the main unit 100. The first mounting cavity 2211 is used for mounting the sludge storage tank 222. The sludge storage tank 222 is detachably connected to the first mounting cavity 2211. The detachable connection can be a plug-in or snap-fit ​​connection, etc. It should be noted that the sludge storage tank 222 needs to be cleaned after a certain period of use. The detachable connection allows for easy removal of the sludge storage tank 222 from the first mounting cavity 2211. Furthermore, the first mounting cavity 2211 is formed by a downward indentation at the top of the clean water tank 221, so the sludge storage tank 222 can be easily removed by simply pulling it upwards. The second mounting cavity 2212 is used for the installation of the suction nozzle assembly 210, which is connected to the sludge storage tank 222. In some embodiments, the suction nozzle assembly 210 includes a third pipe 211 and a suction nozzle 212, wherein the third pipe 211 and the suction nozzle 212 are connected, and the third pipe 211 is connected to the sludge storage tank 222. Furthermore, the purified water tank 221 can deliver purified water to a preset area. It should be noted that the first mounting cavity 2211 and the second mounting cavity 2212 are disposed on the purified water tank 221, and the waste storage tank 222 is installed in the first mounting cavity 2211, while the suction nozzle assembly 210 is installed in the second mounting cavity 2212. In other words, the purified water tank 221 can enclose or surround at least a portion of the structure of the waste storage tank 222 and the suction nozzle assembly 210. This makes the structure of the water tank assembly 220 more compact, and consequently, the structure of the operating module 2001 also more compact. Furthermore, the aforementioned preset area can be the roller brush 20 in the roller brush assembly 240, or it can be the ground or carpet. When the preset area is the roller brush 20 in the roller brush assembly 240, the clean water tank 221 can deliver clean water to the roller brush 20 via a drip pipe or nozzle, making the roller brush 20 wet. The roller brush 20 then cleans the floor or carpet. When there are multiple roller brushes 20 in the roller brush assembly 240 arranged side-by-side, the drip pipe or nozzle is positioned at the roller brush 20 closest to the direction of travel of the roller brush 20. When the preset area is the floor or carpet, the clean water tank 221 can deliver clean water to the floor or carpet via a drip pipe or nozzle during the movement of the cleaning equipment, making the floor or carpet wet. It should be noted that the drip pipe or nozzle is positioned in front of the direction of travel of the roller brush 20, allowing the roller brush 20 to clean the wet floor or carpet during its movement.

[0061] In one embodiment (not shown in the figure), the clean water tank 221 has a third mounting cavity 250, and the roller brush assembly 240 is located in the third mounting cavity 250. That is, the roller brush assembly 240 is located in front of the suction nozzle 212 in the suction nozzle assembly 210. When the cleaning equipment moves to clean, the suction nozzle 212 located behind the roller brush assembly 240 can absorb the sewage on the carpet. At the same time, the third mounting cavity 250 is formed in the clean water tank 221, which increases the space occupied by the sludge storage tank 222 and increases the capacity of the sludge storage tank 222.

[0062] In one embodiment (not shown in the figure), the sludge storage tank 222 has a third mounting cavity 250, and the roller brush assembly 240 is located in the third mounting cavity 250. Similarly, when the third mounting cavity 250 is provided in the sludge storage tank 222, the roller brush assembly 240 is located in front of the suction nozzle 212 in the suction nozzle assembly 210. The third mounting cavity 250 is formed in the sludge storage tank 222, which can increase the space occupied by the water purification tank 221 and increase the capacity of the water purification tank 221.

[0063] In one embodiment, referring to FIG8, the purified water tank 221 and the sludge storage tank 222 together form a third mounting cavity 250, and the roller brush assembly 240 is located in the third mounting cavity 250. At this time, the roller brush assembly 240 is located in front of the suction nozzle 212 in the suction nozzle assembly 210. Since the purified water tank 221 and the sludge storage tank 222 together form a third mounting cavity 250, the installation space of both the purified water tank 221 and the sludge storage tank 222 can be guaranteed, thereby ensuring that the capacity of both the sludge storage tank 222 and the purified water tank 221 is within a good range.

[0064] In one embodiment, referring to Figure 7, the two drive wheels 500 are respectively located on both sides of the sludge storage tank 222 and on the transverse center line of the cleaning equipment, and are symmetrically arranged about the horizontal longitudinal center line of the cleaning equipment. It should be noted that the two drive wheels 500 are located on the transverse center line of the cleaning equipment and on both sides of the sludge storage tank 222. It can be understood that the sludge storage tank 222 is located close to the middle of the cleaning equipment. As the cleaning time of the cleaning equipment increases, the sewage content in the sludge storage tank 222 gradually increases. At this time, the sludge storage tank 222 is located close to the middle of the cleaning equipment so that the center of the cleaning equipment is close to the middle of the cleaning equipment when it moves, which can improve the stability of the cleaning equipment during the movement.

[0065] In one embodiment, referring to FIG7, the roller brush assembly 240 is located behind the two drive wheels 500. This ensures the length of the roller brush 20 within the roller brush assembly 240, thereby increasing the cleaning area of ​​the roller brush 20. Compared to placing the roller brush assembly 240 between the two drive wheels 500, this embodiment effectively increases the cleaning area. Simultaneously, its location behind the drive wheels 500 avoids occupying the space of the sludge storage tank 222, maximizing the installation space of the sludge storage tank 222 and its capacity to hold wastewater, thus increasing the single-operation time of the cleaning equipment.

[0066] In one embodiment, referring to Figures 9 and 10, the first base 110 is provided with a fourth mounting cavity 111, and a portion of the structure of the sludge storage tank 222 is located in the fourth mounting cavity 111. This makes the connection between the working module 2001 and the host 100 more stable. When a portion of the structure of the sludge storage tank 222 is located in the fourth mounting cavity 111, when the cleaning equipment is in use, part of the weight of the sludge storage tank 222 is applied to the first base 110 and another part is applied to the second base 230. This facilitates the host 100 in moving the working module 2001, while also preventing the entire weight of the sludge storage tank 222 from being applied to the second base 230, which would cause a large traction load at the connection between the first base 110 and the second base 230.

[0067] In one embodiment, referring to Figures 9 and 10, the fourth mounting cavity 111 is provided with an air inlet 600, which is connected to the air inlet end of the blower 200. The sludge storage tank 222 is provided with a clearance space corresponding to the air inlet 600. The clearance space is arranged around the air inlet 600. At this time, the gas entering the air inlet end of the blower 200 through the air inlet 600 will generate noise. Since the clearance space is arranged around the air inlet 600, that is, the sludge storage tank 222 is arranged around the air inlet 600, the sludge storage tank 222 can play a role in isolating noise. At the same time, the more sewage in the sludge storage tank 222, the better the sound insulation effect will be. It should be noted that the waste storage tank 222 is provided with a through hole, which is connected to the air inlet 600. The air inlet 600 can create a negative pressure between the waste storage tank 222 and the suction nozzle assembly 210 through the through hole, thereby enabling the suction nozzle assembly 210 to adsorb the ground. In order to ensure the amount of waste stored in the waste storage tank 222, the through hole is located near the top of the waste storage tank 222.

[0068] In one embodiment, referring to Figures 10 and 11, the fourth mounting cavity 111 is further provided with a first exhaust port 180, which is connected to the exhaust end of the fan 200. The bottom of the second base 230 is provided with a second exhaust port 231, which is connected to the first exhaust port 180. It should be noted that the first exhaust port 180 is connected to the exhaust end of the fan 200 through a second pipe 710, and the second exhaust port 231 is connected to the first exhaust port 180 through a fourth pipe 234. Further, in some embodiments, the fourth pipe 234 can be formed on the second base 230. Specifically, the air blown out through the first exhaust port 180 can flow through the fourth pipe 234 and then act on the ground through the second exhaust port 231. At this time, the ground can absorb some of the noise generated when the air blown out through the second exhaust port 231, which can achieve a noise reduction effect. Furthermore, the air blown out by the second exhaust vent 231 acts on the ground, which can also dry the ground. The second exhaust vent 231 is located on the front side of the roller brush assembly 240. It should be noted that a small portion of the wastewater sucked in by the suction nozzle assembly 210 will be discharged by the blower 200 through the first exhaust vent 180 and the second exhaust vent 231. In order to avoid affecting the cleaned carpet area, the second exhaust vent 231 is located on the front side of the roller brush assembly 240.

[0069] Further, referring to Figures 9 and 10, the first exhaust vent 180 is located between the horizontal longitudinal centerline of the main unit 100 and one of the drive wheels 500. It can be understood that the first exhaust vent 180 is offset from the longitudinal centerline of the main unit. Thus, the second pipe 710 connecting the first exhaust vent 180 can make the area on one side of the mounting position located on the longitudinal centerline of the main unit bulge upward, thereby forming a trend where one side is relatively high and the other side is relatively low. It should be noted that when the sludge storage tank is installed at the mounting position, after the sludge storage tank is attached to the mounting position, the bottom of the sludge storage tank can form a structure where one side is relatively high and the other side is relatively low (similar to a step). When the sludge storage tank is in use, the sewage can be concentrated in the relatively low area. It can be understood that concentrating the sewage in one place makes it convenient for the sewage in the sludge storage tank to be discharged. Specifically, a drain outlet can be set in the relatively low area.

[0070] In one embodiment, the air inlet of the fan 200 is oriented downwards and connected to the air inlet 600 via a first pipe 610. It should be noted that when the fan 200 draws air through its air inlet, the moisture content of the gas is relatively high. This can cause water droplets to condense in the first pipe 610. By oriented the air inlet of the fan 200 downwards, the gas moves upwards as it enters the air inlet. In other words, under the influence of gravitational potential energy, the water droplets condensed in the first pipe 610 are less likely to move upwards and enter the fan 200, thus preventing excessive condensation and potential damage to the fan 200. Conversely, if the air inlet of the fan 200 were oriented upwards, the water droplets condensed in the first pipe 610 would enter the fan 200 through the air inlet, causing damage. It should be noted that in some embodiments, the air inlet 600 is positioned relatively low (refer to Figure 10), and the first pipe 610 connecting to the air inlet 600 is relatively short in the height direction. Furthermore, since the air inlet 600 is lowered, a fifth pipe (not shown in the figure) is also provided in the sludge storage tank 222 to ensure the storage capacity of the sludge storage tank 222. One end of the fifth pipe is connected to a through hole. After the sludge storage tank 222 is installed in the designated position, the other end of the fifth pipe is connected to the air inlet 600. In this way, the position of the through hole is ensured by the fifth pipe, thereby avoiding the problem of reduced sludge storage capacity due to the through hole being too low.

[0071] In one embodiment, referring to Figure 8, the outer bottom surface of the second seat 230 is located below the outer bottom surface of the first seat 110. Considering that for the carpet cleaning module, the first exhaust vent 180 faces downwards, and due to the large air volume, the first seat 110 needs a relatively high ground clearance (or ground clearance), otherwise the high-speed airflow will not have enough space for discharge. On the other hand, the suction nozzle assembly 210 is pressed against the carpet and is also floating, and the roller brush 20 is also floating (the floating roller brush 20 also needs a guiding slope; the larger the floating amplitude, the larger the guiding slope, and the larger the space occupied upwards, because space is reserved for upward floating). If the first seat 110 is too high off the ground, the suction nozzle assembly 210 will need a larger guiding slope to overcome bumps (small steps), and the suction nozzle assembly 210 and the roller brush 20 will also need a larger floating height design. All of these will directly increase the volume of the relevant main unit 100. Therefore, an asymmetrical chassis height is adopted to solve this problem, that is, the outer bottom surface of the second seat 230 is located below the outer bottom surface of the first seat 110. Below the outer bottom surface, further, in order to prevent the second seat 230 from being bumped during the movement of the cleaning equipment, in some embodiments the connection between the first seat 110 and the second seat 230 can be transitioned by a first inclined surface. Under the action of the first inclined surface, when the second seat 230 encounters a protruding foreign object, the second seat 230 can be guided by the first inclined surface 232 (see Figure 8) to pass through the protruding foreign object more smoothly. However, this design is not limited to this. In some embodiments, the inclined surface can be directly arranged on the outer bottom surface of the second seat 230. That is to say, the outer bottom surface of the second seat 230 is stepped, and the steps are transitioned by the first inclined surface.

[0072] In one embodiment, the height difference between the first seat 110 and the second seat 230 is greater than 4mm, which ensures that the first exhaust port 180 has a good exhaust effect while also making the structure of the cleaning equipment more compact.

[0073] In one embodiment, referring to FIG9, the cleaning device further includes a battery 300, which is installed on the first base 110 and located in front of the water tank assembly 220. The battery 300 is located on one side of the longitudinal centerline of the main unit 100, and the fan 200 is located on the other side of the horizontal longitudinal centerline of the main unit 100. A fifth mounting cavity 190 is formed between the fan 200 and the battery 300. The fifth mounting cavity 190 can accommodate the first pipe 610 connecting the air inlet of the fan 200 to the air inlet 600, or other wiring structures on the main unit 100, such as a control motherboard. Further, in some embodiments, the caster wheel 400 is located below the fifth mounting cavity 190. It should be noted that since the fifth mounting cavity 190 is formed between the fan 200 and the battery 300, when the caster wheel 400 is located below the mounting cavity, the mounting cavity can provide a certain clearance space for the installation of the caster wheel 400, thus making the structure of the main unit 100 more compact.

[0074] Furthermore, the drive motor 241 in the roller brush assembly 240 is located on one side of the horizontal longitudinal centerline of the main unit 100, with the drive motor 241 and the battery 300 arranged diagonally (see Figure 9). It is understood that the battery 300 is typically heavier than the fan 200. To ensure better balance during use, the drive motor 241 and the battery 300 are arranged diagonally, meaning the drive motor 241 and the fan 200 are located on the same side of the longitudinal centerline of the main unit 100. Of course, in some embodiments, if the battery 300's endurance is guaranteed and the fan 200's weight is greater than the battery 300's weight, then the drive motor 241 can be arranged diagonally with the fan 200.

[0075] In one embodiment, referring to Figures 9 and 10, the cleaning device further includes a monitoring element 160, which is installed on the front side of the water tank assembly 220 and located between the fan 200 and the battery 300. This arrangement allows the structure of the main unit 100 to be further compact, thereby making the structure of the cleaning device more compact.
