The preferred embodiments of the present application will be further described in detail below with reference to the accompanying drawings of this specification.

Referring to FIGS. 1 to 4 , this application provides a cleaning machine. The cleaning machine includes: a housing 10 , a dust box 20 , a water tank 30 , a driving assembly 50 and a fan 60 . The dust box 20, the water tank 30, the driving assembly 50 and the fan 60 are all arranged in the casing 10. The casing 10 can be understood as the surface shell of the cleaning machine, and can also be understood as the support structure that supports the entire cleaning machine. The housing 10 has an installation cavity, and the dust box 20 and the water tank 30 are placed in the cavity. The housing 10 can protect the dust box 20 and the water tank 30, as well as the driving assembly 50 and the fan 60. Among them, the dust box 20 is used to collect dust, debris, etc., and the water tank 30 is used to store cleaning water and provide water during cleaning. The participation of water in cleaning can improve the cleaning effect.

Specifically, the housing 10 is provided with an installation cavity, and the installation cavity is located in the central area of the housing 10; there are two drive components 50, and the two drive components 50 are located on both sides of the center line 110 of the housing 10 and adjacent to the installation cavity; The driving assemblies 50 are symmetrically distributed on both sides with the center line 110 of the housing 10 as the symmetry line. The driving assembly 50 is provided with a driving motor and a driving wheel. The driving motor outputs power to the driving wheel to rotate the driving wheel, thereby driving the cleaning machine to move.

The fan 60 is disposed on the casing 10. Further, the fan 60 can be close to the center line 110 of the casing 10; the center of the fan 60 can also be located on the center line 110 of the casing 10, so that the suction force formed on the left and right sides of the casing 10 The sizes are equal to improve the cleaning effect. The center of the fan 60 can also be located on both sides of the center line 110 of the housing 10 and adjacent to the center line 110 of the housing 10, which can also form effective suction.

The dust box 20 is disposed in the installation cavity and is close to a driving component 50; the water tank 30 is disposed in the installation cavity and is close to another driving component 50. The dust box 20 and the water tank 30 are disposed adjacent to each other. The dust box 20 and the water tank 30 are arranged side by side in the installation cavity. The dust box 20 and the water tank 30 can be close to each other or separated by a certain distance. Being close to each other can make full use of the space in the installation cavity. Spaced at a certain distance from each other can prevent the dust box 20 and the water tank 30 from interfering with each other. Among them, as shown in FIG. 1 , the x direction is the front end of the housing 10 and the y direction is the rear end of the housing 10 .

In this embodiment, the cleaning machine may be a sweeping robot, a mopping machine, or a vacuum cleaner. That , the shape of the housing 10 is generally circular, which reduces edges and corners, avoids scratches on external objects, and prevents damage to external objects. The material of the housing 10 is generally plastic parts, which can be obtained by injection molding and are easy to process.

In the technical solution of this embodiment, the driving assembly 50 is used to drive the housing 10 to move, and during the movement, the fan 60 generates suction to suck the dust moving through the path into the dust box 20 and sprinkle water through the water tank 30 Improve cleaning effect. Among them, the dust box 20 is close to one driving component 50 and the water tank 30 is close to the other driving component 50 to make the layout more reasonable, thereby increasing the volume of the water tank 30 or the dust box 20. This design can enable the water tank 30 to store more The amount of water may make the dust box 20 accommodate more dust and debris to meet the requirements of cleaning work.

In the related art, the dust box 20 is placed at the center of the housing 10, which compresses the space of the water tank 30, resulting in a smaller volume of the water tank 30. Even if the corner space of other structures is fully utilized, the water tank 30 still needs to be designed in a profiling manner. The structure of the water tank 30 processed in this way is complex and the cost is high. Moreover, even in a profiling design, the space of the water tank 30 is difficult to be greatly improved.

From the further description of the above embodiment, it can be seen that the dust box 20 is close to one driving assembly 50, and the water tank 30 is close to another driving assembly 50. In this way, the water tank 30 and the dust box 20 are both eccentrically arranged. The position of the dust box 20 is set eccentrically, so that the center of the dust box 20 deviates from the center of the housing 10 . Thereby, the space for placing the water tank 30 is increased, and the water tank 30 designed in this way can store more water and meet the water requirement for cleaning work. In addition, the profiling design of the water tank 30 can also be reduced, the processing difficulty is reduced, and the cost is reduced.

Moreover, the profile design and complex structure make it extremely inconvenient to install the sink and the installation process is cumbersome. This embodiment can simplify the installation process and improve installation efficiency.

The center of the dust box 20 is offset from the center of the housing 10, and the center of the housing 10 is the center of the shape, that is, the centroid. The housing 10 is arranged symmetrically from front to back, left and right, and its center of shape is also the center of gravity. Similarly, the center of the dust box 20 is the centroid of the dust box 20 . Through the eccentric arrangement of the dust box 20, the distance between the dust box 20 and the inner wall surface of the housing 10 can be increased, and the space for placing the water tank 30 can be increased, and the volume of the water tank 30 can be increased accordingly.

In the above embodiment, if the volume of the installation cavity is V0 and the volume of the dust box 20 is V1, then: 20%≤V1/V0≤80% is satisfied. Within this range, it is ensured that the dust box 20 has sufficient volume to collect dust. If it is less than 20%, the volume of the dust box 20 is too small and it is difficult to have enough space to accommodate dust. If it is greater than 80%, the volume of the dust box 20 is too large, occupying a larger space in the installation cavity, and compressing the volume of the water tank 30 .

Within this range, it is guaranteed that the water tank 30 has enough water to store water. If less than 20%, the volume of the water tank 30 Too small to have enough capacity to store water. If it is greater than 80%, the volume of the water tank 30 is too large, occupying a larger space in the installation cavity, and compressing the volume of the dust box 20 . Specifically, the ratio of the volume V2 of the water tank 30 to the volume V0 of the installation cavity may be 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30% , 31%, 32%, 33, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47% ,48%,49%,50%,51%,52%,53%,54%,55%,56%,57%,58%,59%,60%,61%,62%,63%,64 %, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79% or 80%.

In the above embodiment, if the volume of the dust box 20 is V1 and the volume of the water tank 30 is V2, then: 20%≤V2/V1≤80% is satisfied. Specifically, the ratio of the volume V1 of the dust box 20 to the volume V2 of the water tank 30 may be 20%, 21%, 22%, 23%, 24%, 25%, 26%, 27%, 28%, 29%, 30 %, 31%, 32%, 33, 34%, 35%, 36%, 37%, 38%, 39%, 40%, 41%, 42%, 43%, 44%, 45%, 46%, 47 %, 48%, 49%, 50%, 51%, 52%, 53%, 54%, 55%, 56%, 57%, 58%, 59%, 60%, 61%, 62%, 63%, 64%, 65%, 66%, 67%, 68%, 69%, 70%, 71%, 72%, 73%, 74%, 75%, 76%, 77%, 78%, 79% or 80% . Generally speaking, the volume of the dust box 20 is larger than the volume of the water tank 30 .

Refer to Figure 5, in order to effectively collect dust. The dust box 20 includes a lower box 210. The lower box 210 includes a bottom plate 211 and a windward plate 212. The fan 60 is located at the rear end area of the housing 10. The windward plate 212 is located on the side of the bottom plate 211 away from the fan 60. The windward plate 212 and the bottom plate 211 are arranged at an angle, and the surface of the windward plate 212 is provided with a dust collection port 213, which at least partially corresponds to the fan 60; driven by the air flow generated by the fan 60, dust can enter the dust box 20 through the dust collection port 213. Inside. In order to improve the dust collection effect, the dust collection port 213 can be directly corresponding to the fan 60, so that more dust can enter the dust box 20.

The dust box 20 also includes a filter screen 240 , which is disposed on a side of the bottom plate 211 close to the fan 60 . The filter screen 240 can be a full-surface filtering structure. It is also possible that the dust box 20 includes a bracket 250, the bracket 250 is arranged on the bottom plate 211, and the filter screen 240 is arranged on the bracket 250. The bracket 250 can improve the firmness of the filter screen 240. The filter screen 240 can trap dust. When the airflow enters through the dust collecting port 213, through the filtering effect of the filter screen 240, the dust is filtered by the filter screen 240 in the dust box 20.

Furthermore, in order to better complete the dust collection function of the dust box 20, the center of the dust collection port 213 can also correspond to the center of the fan 60. Generally, the wind force at the center of the fan 60 is the largest and drives the most dust. Through dust collection The facing arrangement of the port 213 can improve the dust collection effect. That is to say, although the center of the dust box 20 is offset from the center of the fan 60 , the dust collecting port 213 is provided corresponding to the fan 60 . That is to say, the center of the dust box 20 is offset from the center of the fan 60, but the dust collecting port 213 is arranged directly opposite.

Of course, the opening size of the dust collection port 213 is also related to the dust collection effect. The larger the opening, the better the dust collection effect. To this end, the windward plate 212 and the bottom plate 211 are arranged at an angle. The inclined arrangement can increase the contact area between the windward plate 212 and the airflow generated by the fan 60. This can increase the opening area of the dust collecting port 213 and collect more dust. dust.

In addition, the inclination direction of the windward plate 212 is tilted away from the fan 60 from the bottom plate 211, which can also increase the volume of the dust box 20. And an avoidance space is formed below the windward plate 212, and a roller brush for cleaning dust can be placed in the avoidance space.

In order to reduce dust leakage, the lower box 210 further includes a baffle 214 . The baffle 214 is located on the side of the windward plate 212 facing the filter 240 , and has a rotating cover on the dust collecting port 213 . The baffle 214 is located inside the dust box 20 . When the cleaning machine is working, the fan 60 works, and the fan 60 drives the air flow. Under the action of the wind caused by the air flow, the baffle 214 originally covering the dust collection port 213 is blown open, and the dust can enter the inside of the dust box 20 . When the cleaning machine stops working, the fan 60 also stops working. In this way, the baffle 214 lacks the blowing effect of the air flow. Under the action of its own gravity, the baffle 214 automatically falls and snaps onto the dust collection port 213, thereby preventing dust from overflowing through the dust collection port 213.

In addition, in this embodiment, the baffle 214 is provided with a rotating shaft. The rotating shaft is arranged at the upper edge of the dust collecting port 213. The rotating shaft can rotate in both up and down directions. In this way, the baffle 214 can also be flipped up and down. It is beneficial to give full play to the gravity effect of the baffle 214.

Further, in order to improve the shielding effect of the baffle 214 on the dust collection port 213, the lower box 210 also includes a sealing ring 215. The sealing ring 215 is provided on the baffle 214 or the windward plate 212. The windward plate 212 covers the dust collection port 213. The sealing ring 215 seals the dust collecting port 213. The sealing ring 215 has a certain degree of flexibility. For example, the sealing ring 215 is made of (Ethylene-vinyl acetate copolymer, EVA) ethylene-vinyl acetate copolymer. Ethylene-vinyl acetate copolymer has good softness, flexibility, shockproof, anti-slip and strong pressure resistance.

Through the arrangement of the sealing ring 215, when the baffle 214 covers the dust collection port 213, the sealing ring 215 can better contact the baffle 214, reducing the gap between the baffle 214 and the outer edge of the dust collection port 213. Thereby reducing the leakage of dust.

Among them, there are two installation positions of the sealing ring 215 .

In the first type, the sealing ring 215 is arranged on the baffle 214 , and the sealing ring 215 is bonded or embedded on the baffle 214 . The sealing ring 215 swings as the baffle 214 swings up and down. This method can reduce design changes to the windward plate 212.

Second, the sealing ring 215 is provided on the windward plate 212. Specifically, the sealing ring 215 is embedded or pasted on the outer edge of the dust collecting port 213, and protrudes from the surface of the windward plate 212, and covers the dust collection at the baffle 214. When opening 213, the sealing ring 215 and the baffle 214 complete contact. In this way, the gravity of the baffle 214 can be reduced, and the baffle 214 can be blown up more easily during dust collection.

In the above embodiment, the dust collected in a centralized manner needs to be cleaned. The lower box 210 also includes two side plates 216, which are arranged on opposite sides of the bottom plate 211. One end of the side plate 216 is connected to the windward plate 212, and the other end is connected to the filter screen 240; the dust box 20 also includes an upper cover plate 220 and The handle 230 and the upper cover 220 are covered with the lower box 210. A dust collection chamber for storing dust is formed between the upper cover 220 and the lower box 210. The handle 230 is rotatably connected to the upper cover 220 and the upper cover. A storage slot 221 is provided on the upper surface of 220, and the storage slot 221 is used to store the handle 230. The upper surface of the upper cover 220 is also provided with an escape opening 222. The escape opening 222 is connected to the storage groove 221. When the dust box 20 is disassembled, the handle 230 is pulled through the escape opening 222, which makes it easier for the handle 230 to bear force and make the handle 230 stronger. Turn it out from the storage slot 221. Correspondingly, a groove 231 is also provided at the position of the handle corresponding to the escape opening 222. Through the cooperation of the groove 231 and the escape opening 222, the operating space for prying the handle 230 is increased when the handle 230 is pulled.

Among them, the dust box 20 is detachably installed in the casing 10. In order to facilitate the disassembly, the dust box 20 can be easily pulled by the handle 230 to receive force, and the dust box 20 can be quickly pulled out and separated from the casing 10. Through this detachable method, when the dust needs to be cleaned, the dust box 20 can be removed from the cleaning machine, and then the dust can be concentrated.

In addition, the water tank 30 is usually fixed in the housing 10 and does not need to be moved under normal circumstances. This also ensures that the overall cleaning machine is stronger and prevents the structure from being too loose.

When cleaning some larger debris, the dust box 20 can be disassembled for centralized processing. However, for smaller debris, the base station 70 can automatically suction the debris for centralized processing. Specifically, the side plate 216 of the lower box 210 is provided with a dust extraction port 201, and the surface of the housing 10 is provided with a dust extraction port 101. The cleaning machine also includes a dust extraction pipe 40, and one end of the dust extraction pipe 40 is connected to the dust extraction port 101. , the other end is connected to the dust exhaust port 201; after the cleaning machine completes its work, the cleaning machine automatically returns to the base station 70. The base station 70 is connected to the dust extraction port 101, and the base station 70 generates suction. Under the action of the suction, the dust box 20 The dust will be sucked out through the dust exhaust port 201, the dust extraction pipe 40 and the dust extraction port 101 in sequence. This enables centralized processing of small-volume debris.

In order to reduce the random leakage of dust, the lower box 210 of the dust box 20 includes a rotating shaft cover 217. The rotating shaft cover 217 is provided corresponding to the dust extraction duct 40, and the rotating cover is provided at the dust exhaust port 201. When dust is extracted, airflow is generated under the action of suction, and the airflow impacts the rotating shaft cover 217, and the rotating shaft cover 217 rotates and opens, thereby opening up the connection between the dust box 20 and the outside world, and dust can pass through the dust extraction duct 40 smoothly. Moreover, the rotating shaft cover 217 is connected with an elastic member. Under the impact of air flow, the rotating shaft When the cover 217 is opened, the elastic member is deformed and the elastic member generates a restoring force. When the suction operation is stopped, the suction force disappears and there is no more airflow impacting the rotating shaft cover 217. The rotating shaft cover 217 drives the rotating shaft cover under the action of the elastic restoring force. 217 close the dust outlet 201 to avoid dust leakage.

Referring to FIG. 6 , in order to ensure that dust can be effectively sucked out, the dust extraction duct 40 includes a first connecting section 410 and a second connecting section 420 . An angle θ is formed between the first connecting section 410 and the second connecting section 420 , thus satisfying :90°＜θ≤180°.

The cleaning machine only performs the dust extraction function when it returns to the base station 70 . The base station 70 is provided with a management library 710. When the cleaning machine moves to the management library 710, the management library 710 half wraps the cleaning machine. That is to say, the management library 710 can only be in contact with half of the cleaning machine. Therefore, the dust extraction duct 40 extends from the side plate 216 of the dust box 20 and needs to extend toward the management warehouse 710 . Therefore, the dust extraction duct 40 has a certain bending angle.

When the airflow passes through the dust extraction duct 40, the airflow will come into contact with the inner wall surface of the dust extraction duct 40. If the angle between the first connecting section 410 and the second connecting section 420 is 90°, the airflow passes through the first connecting section 410 and directly impacts on the second connecting section 420, which will cause the suction force to be slowed down. In addition, if the two are set at right angles, or less than 90°, dust will accumulate in the corners, making it difficult to clean.

For this reason, the angle between the first connecting section 410 and the second connecting section 420 is greater than 90° to prevent the airflow from impacting at the corner position and reduce the friction between the airflow and the pipe wall. In addition, the angle between the first connecting section 410 and the second connecting section 420 can be equal to 180°, so that the position of the dust extraction port 101 is closest to the position of the dust box 20, and the first connecting section 410 and the second connecting section 420 form a line. straight line. Therefore, 90°<θ≤180°. Specifically, the θ angle may be 95°, 100°, 105°, 110°, 115°, 120°, 125°, 130°, 135°, 140°, 145°, 150°, 155°, 160°, 165 °, 170°, 175°, 180°.
