[0039] The mobile robot consists of a base, a fan, a wastewater tank, drive wheels, a suction nozzle assembly, and a water tank. These components are mounted on the base, and the drive wheels contact the ground, moving the base and consequently the fan, wastewater tank, suction nozzle assembly, and clean water tank for cleaning. Existing cleaning equipment arranges the wastewater tank, clean 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.

[0040] This utility model proposes a cleaning device.

[0041] Please see Figure 1 , Figure 2 , Figure 3 In one embodiment of this utility model, the cleaning device includes a main unit 100 and an operating module 200. The main unit 100 includes a first base 110, a fan 120 mounted on the first base 110, two drive wheels 130, and casters 140. The two drive wheels 130 are symmetrically arranged about the main unit 100, specifically, they are symmetrically arranged about the horizontal longitudinal centerline of the main unit 100. The casters 140 and the two drive wheels 130 form a three-point support, enabling the main unit 100 to be stably placed on the ground. The drive wheels 130 drive the main unit 100 to move and turn.

[0042] The operating module 200 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 120 are horizontally arranged. The suction nozzle of the suction nozzle assembly 210, the water tank assembly 220, and the blower 120 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 wastewater tank 222, wherein the blower 120 is connected to the wastewater tank 222, and the suction nozzle assembly 210 is connected to the wastewater tank 222. The operating module 200 also includes a roller brush assembly 240, and the clean water tank 221 can deliver clean water to the roller brush assembly 240. Water is used to wash the carpet with the roller brush assembly 240. After washing, the suction nozzle assembly 210 absorbs the wastewater on the carpet and it enters the wastewater tank 222. The roller brush assembly 240 includes a roller brush 242 and a drive motor 241 that drives the roller brush 242 to rotate. It should be noted that the clean water tank 211 can deliver clean water to the roller brush assembly 240 by dripping or spraying. That is, the clean water tank 211 is equipped with a drip tube or nozzle. At this time, the roller brush assembly 240 is located below the clean water tank 211. The clean water tank 211 delivers clean water to the roller brush 242 in the roller brush assembly 240 through the drip tube or nozzle. At this time, the roller brush 242 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 120 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.

[0043] In one embodiment, reference Figure 2 , Figure 4 The operating module 200 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 operating module 200 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 operating module 200 can be removed from the main unit 100, facilitating the replacement of the entire operating module 200.

[0044] In one embodiment, reference Figure 1 , Figure 3The water tank assembly 220 includes a clean water tank 221 and a wastewater 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 wastewater tank 222. The wastewater tank 222 is detachably connected to the first mounting cavity 2211. The detachable connection can be by plugging or snapping, etc. It should be noted that the wastewater tank 222 needs to be cleaned after a certain period of use. The connection method facilitates the removal of the wastewater 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 wastewater 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 wastewater 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 wastewater 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 wastewater 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 purified water tank 221 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 200 also more compact. Furthermore, the aforementioned preset area can be the roller brush 242 in the roller brush assembly 240, or it can be the ground or a carpet. When the preset area is the roller brush 242 in the roller brush assembly 240, the clean water tank 221 can deliver clean water to the roller brush 242 via a drip pipe or nozzle, making the roller brush 242 wet. The roller brush 242 then cleans the floor or carpet. When there are multiple roller brushes 242 in the roller brush assembly 240 arranged side-by-side, the drip pipe or nozzle is positioned at the roller brush 242 closest to the direction of travel of the roller brush 242. 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 242, allowing the roller brush 242 to clean the wet floor or carpet during its movement.

[0045] 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 device 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 sewage tank 222 and increases the capacity of the sewage tank 222.

[0046] In one embodiment (not shown in the figure), the wastewater 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 wastewater 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 wastewater tank 222, which can increase the space occupied by the clean water tank 221 and increase the capacity of the clean water tank 221.

[0047] In one embodiment, reference Figure 3 The clean water tank 221 and the wastewater tank 222 together form a third mounting cavity 250. 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 clean water tank 221 and the wastewater tank 222 together form a third mounting cavity 250, the installation space of both the clean water tank 221 and the wastewater tank 222 can be guaranteed, so that the capacity of both the wastewater tank 222 and the clean water tank 221 is within a good range.

[0048] In one embodiment, reference Figure 2 The two drive wheels 130 are respectively located on both sides of the sewage 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 130 are located on the transverse center of the cleaning equipment and on both sides of the sewage tank 222. It can be understood that the sewage 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 sewage tank 222 gradually increases. At this time, the sewage 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.

[0049] In one embodiment, reference Figure 2The roller brush assembly 240 is located behind the two drive wheels 130, which ensures the length of the roller brush 242 within the assembly, thereby increasing the cleaning area of ​​the roller brush 242. Compared to placing the roller brush assembly 240 between the two drive wheels 130, this embodiment effectively increases the cleaning area. Furthermore, its location behind the drive wheels 130 avoids encroaching on the space of the wastewater tank 222, maximizing the installation space for the wastewater tank 222 and its capacity to hold wastewater, thus increasing the single-operation time of the cleaning equipment.

[0050] In one embodiment, refer to 4, Figure 5 The first base 110 is provided with a fourth mounting cavity 111, and part of the structure of the sewage tank 222 is located in the fourth mounting cavity 111. This makes the connection between the working module 200 and the host 100 more stable. When part of the structure of the sewage tank 222 is located in the fourth mounting cavity 111, when the cleaning equipment is in use, part of the weight of the sewage tank 222 is applied to the first base 110 and the other part is applied to the second base 230. This makes it easier for the host 100 to move the working module 200. At the same time, it can also prevent the entire weight of the sewage tank 222 from being applied to the second base 230, which would cause the connection between the first base 110 and the second base 230 to be subjected to a large traction load.

[0051] In one embodiment, reference Figure 4 , Figure 5 The fourth mounting cavity 111 is provided with an air inlet 170, which is connected to the air inlet end of the blower 120. The sewage tank 222 is provided with a clearance space corresponding to the air inlet 170. The clearance space is arranged around the air inlet 170. At this time, the gas entering the air inlet end of the blower 120 through the air inlet 170 will generate noise. Since the clearance space is arranged around the air inlet 170, that is, the sewage tank 222 is arranged around the air inlet 170, the sewage tank 222 can play a role in isolating noise. At the same time, the more sewage in the sewage tank 222, the better the sound insulation effect will be. It should be noted that the sewage tank 222 is provided with a through hole, which is connected to the air inlet 170. The air inlet 170 can create a negative pressure between the sewage 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 sewage stored in the sewage tank 222, the through hole is located near the top of the sewage tank 222.

[0052] In one embodiment, reference Figure 5 , Figure 6The fourth mounting cavity 111 is further provided with a first exhaust port 180, which is connected to the exhaust end of the fan 120. 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 120 via a second pipe 181, and the second exhaust port 231 is connected to the first exhaust port 180 via 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, achieving a noise reduction effect. Furthermore, the air blown out through the second exhaust port 231 acting on the ground 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 through the blower 120 via 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.

[0053] Further, refer to Figure 4 , Figure 5 The first exhaust vent 180 is located between the horizontal longitudinal centerline of the main unit 100 and one of the drive wheels 130. It can be understood that the first exhaust vent 180 is offset from the longitudinal centerline of the main unit. Thus, the second pipe 181 connecting the first exhaust vent 180 can make the mounting position 110 protrude upward on one side of the longitudinal centerline of the main unit, thereby forming a trend where one side is relatively high and the other side is relatively low. It should be noted that when the sewage tank is installed at the mounting position 110, after the sewage tank is attached to the mounting position 100, the bottom of the sewage tank can form a structure where one side is relatively high and the other side is relatively low (similar to a step). When the sewage 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 easier for the sewage in the sewage tank to be discharged. Specifically, a drain outlet can be set in the relatively low area.

[0054] In one embodiment, the air inlet of the fan 120 is oriented downwards and connected to the air inlet 170 via a first pipe 171. It should be noted that when the fan 120 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 171. By oriented the air inlet of the fan 120 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 171 are less likely to move upwards and enter the fan 120, thus preventing excessive condensation and potential damage to the fan 120. Conversely, if the air inlet of the fan 120 were oriented upwards, the water droplets condensed in the first pipe 171 would enter the fan 120 through the air inlet, causing damage. It should be noted that in some embodiments, the air inlet 170 is positioned relatively low (see reference). Figure 5 At this point, the first pipe 171 connecting to the air inlet 170 is relatively short in the vertical direction. Furthermore, since the position of the air inlet 170 is lowered, in order to ensure the storage capacity of the sewage tank 222, a fifth pipe (not shown in the figure) is also installed in the sewage tank 222. One end of the fifth pipe is connected to a through hole. After the sewage tank 222 is installed in the designated position, the other end of the fifth pipe is connected to the air inlet 170. In this way, the position of the through hole can be ensured through the fifth pipe, thereby avoiding the problem of reduced sewage storage capacity caused by the through hole being too low.

[0055] In one embodiment, reference Figure 3The outer bottom surface of the second seat 230 is located below the outer bottom surface of the first seat 110. Considering that the first exhaust vent 180 of the carpet cleaning module faces downward, and the air volume is relatively large, the first seat 110 needs to have a high ground clearance (or ground clearance), otherwise the high-speed airflow will not have enough space to be discharged. On the other hand, the nozzle assembly 210 is pressed against the carpet and is also floating, as is the roller brush 242 (the floating roller brush 242 also requires a guiding slope; the greater the floating amplitude, the larger the guiding slope, and the more upward space it occupies, because space is reserved for upward floating). If the first seat 110 is too high off the ground, the nozzle assembly 210 will need a larger guiding slope to overcome bumps (small steps), and the nozzle assembly 210 and roller brush 242 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. Furthermore, to avoid the second seat 230 being tripped 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 slope. Under the action of the first slope, when the second seat 230 encounters a protruding foreign object, the second seat 230 can pass through the first slope 232 (see Figure 3 The design guides the passage of protruding foreign objects 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, the outer bottom surface of the second seat 230 is stepped, and the steps are transitioned by the first inclined surface.

[0056] 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.

[0057] In one embodiment, reference Figure 4The cleaning device also includes a battery 150, which is installed on the first base 110 and located in front of the water tank assembly 220. The battery 150 is located on one side of the longitudinal centerline of the main unit 100, and the fan 120 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 120 and the battery 150. The fifth mounting cavity 190 can accommodate the first pipe 171 connecting the air inlet of the fan 120 to the air inlet 170, or other wiring structures on the main unit 100, such as a control motherboard. Further, in some embodiments, the caster wheel 140 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 amount of clearance for the installation of the caster wheel 400, thus making the structure of the main unit 100 more compact.

[0058] Furthermore, the drive motor 241 in the roller brush assembly 240 is located on one side of the longitudinal centerline of the main unit 100, wherein the drive motor 241 and the battery 150 are arranged diagonally (see...). Figure 4 It is understood that the battery 150 is typically heavier than the fan 120. To ensure better balance during operation, the drive motor 241 and the battery 150 are positioned diagonally opposite each other; that is, the drive motor 241 and the fan 120 are located on the same side of the longitudinal centerline of the main unit 100. However, in some embodiments, if the battery 150's battery life is guaranteed and the fan 120 is heavier than the battery 150, the drive motor 241 can be positioned diagonally opposite the fan 120.

[0059] In one embodiment, reference Figure 4 , Figure 5 The cleaning equipment also includes a radar 160, which is installed on the front side of the water tank assembly 220 and located between the fan 120 and the battery 150. This arrangement allows the structure of the main unit 100 to be further compact, thereby making the structure of the cleaning equipment more compact.
