[0024] To make the above-mentioned objects, features, and advantages of the present invention more readily apparent, specific embodiments of the present invention are described in detail below with reference to the accompanying drawings. The following description sets forth numerous specific details to facilitate a full understanding of the present invention. However, the present invention can be implemented in many other ways than those described herein, and those skilled in the art may make similar modifications without departing from the scope of the present invention. Therefore, the present invention is not limited to the specific embodiments disclosed below.

[0025] See also Figure 1 and Figure 2According to one aspect of an embodiment of the present invention, a cleaning robot is provided, including a shell 1, a fan and an air volume adjustment module, the shell 1 forms an installation cavity, and the fan and the air volume adjustment module are installed in the installation cavity; the air volume adjustment module includes a floating component 2, a wind shield component 3 and a separation box, the separation box is installed on the bottom plate of the shell 1, the separation box includes a separation chamber and an air outlet channel 5, the air outlet channel 5 is connected to the separation chamber, the floating component 2 is provided in the separation chamber, and the wind shield component 3 is provided in the air outlet channel 5, the floating component 2 moves under the action of the suction medium in the separation chamber, and the floating component 2 drives the wind shield component 3 to move in the air outlet channel 5.

[0026] In an exemplary embodiment, the separation box is a circular, square, or other shaped box with a removable top cover 4. It is used to collect dust particles, liquids, and other contaminants sucked in by the cleaning robot. The fan is located in the air outlet 5. The suction medium comprises the wind in the separation chamber and the sucked-in liquid or dust particles. The wind acts from the bottom of the separation box toward the floating assembly 2, providing a force for its movement. When the liquid reaches a certain level and contacts the floating assembly 2, it provides buoyancy, allowing the dust particles to settle on the filter plate 23 of the floating assembly 2. The force exerted by the dust particles on the floating assembly 2 is opposite to that of the wind. It should be noted that when the floating assembly 2 moves away from the bottom of the separation box under the influence of wind or liquid, it can drive the wind shield assembly 3 toward the outlet of the air outlet 5, increasing the wind resistance at the outlet and reducing the amount of air entering. When the floating assembly 2 moves toward the bottom of the separation box under the influence of dust particles, it can drive the wind shield assembly 3 toward the outlet of the air outlet 5, increasing the amount of air entering. This eliminates the need to set multiple sensors to adjust the level of the incoming wind force, resulting in low cost and simple device structure.

[0027] The floating assembly 2 includes a buoyancy element 21, a guide rod 22 and a top block 24. One end of the guide rod 22 is connected to the top cover 4 of the separation box, and the other end of the guide rod 22 is connected to the filter plate 23. The filter plate 23 is used to separate the inhaled particles and liquid. The top block 24 is sleeved on the guide rod 22.

[0028] In an exemplary embodiment, as Figure 3As shown, the buoyancy element 21 is a spherical structure or a hexahedral structure. This application takes the buoyancy element 21 as an example, which is a buoyancy ball. The buoyancy ball is fixed on the guide rod. Specifically, the buoyancy ball and the guide rod are an integrally formed structure. The end of the guide rod close to the separation box top cover 4 is a free end. When the buoyancy ball is subjected to an upward force, the guide rod can lift the top cover 4. The top cover 4 and the separation box are detachably mounted. The top block 24 is mounted on the end of the guide rod 22 close to the separation box top cover 4. The top block 24 and the guide rod are also an integrally formed structure. It should be noted that a filter plate 23 is provided in the separation box, and the end of the guide rod connected to the filter plate 23 is suspended above the above, for separating the particles sucked into the separation box from the liquid. The addition of the filter plate 23 enables the cleaning robot in this application to increase the suction force on the impurities when encountering larger particulate impurities, thereby ensuring the cleaning robot's ability to adaptively adjust the wind speed.

[0029] The windshield assembly 3 includes a push rod 31, a first elastic element 33 and a baffle 32. The baffle 32 is fixed to one end of the push rod 31, and the first end 34 is fixed to the other end of the push rod 31. The first end 34 is used to abut against the top block 24; the first elastic element 33 is sleeved on the push rod 31.

[0030] In an exemplary embodiment, the push rod 31 is a rod-shaped structure such as a cylindrical guide rod or a square guide rod, and the baffle 32 is a plate-shaped structure adapted to the shape of the disposal port. For example, taking the push rod 31 as a square guide rod, one end of the push rod 31 is connected to the baffle 32 and drives the baffle 32 to move in the air outlet 5. The other end of the push rod 31 is fixedly provided with the first end portion 34, which is used to abut against the top block 24 and convert the force applied to the top block 24 in the first direction into a force that pushes the windshield assembly 3 to move in the second direction. Specifically, the baffle 32, push rod 31, and first end portion 34 are all integrally formed structures. The first elastic element 33 is a spring. The spring is compressed and deformed when the top block 24 moves toward the top cover 4. When the top block 24 moves toward the bottom of the separation box, the pressure applied to the spring disappears and the spring recovers, providing a reset force for the push rod 31. When uncompressed, the spring provides a restoring force for the push rod 31 to return to its original position, helping to maintain the stability of the windshield assembly 3 and preventing the push rod 31 from deflecting or becoming unbalanced due to external forces or vibrations. The spring's restoring ability allows the push rod 31 to quickly return to its original position after being freed from the compression of the top block 24, thereby maintaining the stability of the overall structure.

[0031] A push rod mounting hole is provided on the side wall of the separation box, the push rod 31 is arranged in the push rod mounting hole, the baffle 32 is arranged in the air outlet channel 5, and the first elastic element 33 and the first end 34 are both arranged in the separation cavity.

[0032] In an exemplary embodiment, the push rod 31 is installed in the push rod mounting hole, and one end of the push rod 31 connected to the baffle 32 extends out of the push rod mounting hole. The push rod 31 in the separation box is sleeved with the first elastic element 33, i.e., a spring. When the push rod 31 is not squeezed by the top block 24, the first end 34 abuts against the top block 24, and the spring is not deformed by pressure. When the buoyancy ball moves upward due to the buoyancy of wind or liquid, the spring is deformed by pressure. It should be noted that the size of the push rod mounting hole set on the side wall of the separation box matches the cross-section of the push rod 31, so as to prevent the push rod 31 from shaking during movement due to the excessive size of the mounting hole, thereby improving the stability of the windshield assembly 3 during movement.

[0033] The top block 24 and the first end portion 34 are both wedge-shaped block structures. The top block 24 drives the first end portion 34 to move along a first direction. The first direction represents the moving direction between the top block 24 and the push rod mounting hole.

[0034] In an exemplary embodiment, the top block 24 and the first end portion 34 are both wedge-shaped block structures provided with an inclined surface. Preferably, the inclined surface of the top block 24 and the inclined surface of the first end portion 34 are parallel to each other, and the inclined surface of the wedge-shaped structure can convert vertical force into horizontal force, thereby realizing force transmission and conversion. Through the mutually abutting inclined surfaces, the movement of one wedge-shaped block structure can be effectively transmitted to another wedge-shaped block structure. The inclined surface of the wedge-shaped structure has a certain bearing capacity and can effectively disperse and transmit the load, so that the structure as a whole can withstand a large force, and the inclined surface contact can automatically adjust to a certain extent and maintain a stable motion relationship, reducing the need for maintenance and adjustment, and the structure is simple and reliable.

[0035] The buoyancy element 21 is circumferentially provided with a first limiting portion 25, and the inner wall surface of the separation box is circumferentially provided with a second limiting portion. The first limiting portion 25 cooperates with the second limiting portion to divide the separation cavity into a first cavity and a second cavity. The first limiting portion 25 moves in the first cavity along the second direction, and the second direction is perpendicular to the first direction. The filter plate 23 is suspended in the second cavity.

[0036] In an exemplary embodiment, taking the buoyancy element 21 as an example, the first limiting portion 25 is a ring mounted on the buoyancy ball, the second limiting portion is a limiting plate disposed on the inner wall of the separation box, the limiting plate and the bottom plate of the separation box are parallel to each other, and the first limiting portion 25 is mounted on the second limiting portion, and the second limiting portion is used to limit the movement of the buoyancy element 21 in the first cavity. It should be noted that by providing the first limiting portion 25, the floating assembly 2 is suspended, and the filter plate 23 is suspended in the second cavity. Since large particles are separated in time by the filter plate 23, the air outlet and internal pipes of the robot can remain unobstructed, thereby ensuring that the suction force is not affected. This enables the robot to collect impurities more efficiently during the cleaning process, thereby improving the cleaning speed and effect.

[0037] The side wall of the shell 1 is provided with an air outlet, and the air outlet is connected to the air outlet channel 5. In an exemplary embodiment, the above-mentioned air outlet is provided on the shell 1, and the above-mentioned fan is installed in the installation cavity on the side of the air outlet to facilitate the wind output in the separation cavity. It should be noted that the arrangement of the fan at the air outlet also helps to reduce the noise and vibration generated during cleaning. Since the fan is located at the air outlet, the noise and vibration generated by it have little impact on the overall operation of the robot and the roller brush assembly 7, so the user experience can be improved. And the design of the fan being arranged at the air outlet is also conducive to heat dissipation. The cleaning robot will generate a certain amount of heat when working, and the fan can discharge the heat in time at the exhaust port to prevent the robot from overheating and affecting its performance and life.

[0038] The cleaning robot also includes a walking assembly 6, which includes a walking wheel 61 and at least two universal wheels 62. At least two universal wheels 62 are relatively arranged on the end face of the shell 1 close to the ground. The walking wheel 61 is arranged at intervals between the universal wheels 62. The universal wheels 62 are used to change the walking direction of the cleaning robot, and the walking wheel 61 is used to drive the cleaning robot to walk.

[0039] In an exemplary embodiment, as Figure 4 and Figure 5 As shown, the above-mentioned running wheel 61 and universal wheel 62 are provided on the end surface of the housing 1 close to the ground, and the two universal wheels 62 are symmetrically arranged with the center line of the bottom of the housing 1 as the axis. Preferably, the above-mentioned running wheel 61 is arranged on the perpendicular bisector of the center line to ensure the balance of the cleaning robot when walking.

[0040] The cleaning robot also includes a roller brush assembly 7 arranged on the shell 1. The end face of the shell 1 close to the ground is provided with an air inlet, and the roller brush assembly 7 is installed at the air inlet. The roller brush assembly 7 is protruded from the end face of the shell 1 close to the ground and is arranged opposite to the walking wheel 61.

[0041] According to another aspect of an embodiment of the present invention, a cleaning system is provided, comprising a base station and the above-mentioned cleaning robot, wherein the cleaning robot is matched with the base station.

[0042] Working Principle: First, the cleaning robot is powered on, and the universal wheels 62, running wheels 61, fan, and roller brush assembly 7 all begin operating. Specifically, the robot sweeps trash to the air inlet using the roller brush assembly 7, and uses the suction provided by the fan to draw the trash into the separation chamber within the robot. The universal wheels 62 are designed to automatically adjust their direction of movement if a collision sensor, infrared sensor, or other device detects an obstruction, allowing the running wheels 61 to continue moving in the adjusted direction. When the trash on the ground consists of particulate matter such as dust, an airflow containing impurities flows through the robot's air duct. If the dust is heavy and contains large particles, they will settle onto the filter plate 23, increasing the weight of the filter plate 23 and driving the buoyancy ball downward, prompting the robot to increase the wind force to draw the large particles into the separation chamber. Specifically, the top block 24, driven by the buoyancy ball, moves vertically downward. In the initial state, the top block 24 and the inclined surface abutting the first end 34 move vertically downward in sync. At this point, the windshield assembly 3 is no longer subject to the squeezing force of the top block 24. The push rod 31, under the rebound force of the first elastic element 33, drives the baffle 32 to move in the air outlet channel 5 away from the air outlet. The resistance at the air outlet is now reduced, and the wind force at the air inlet is increased, thereby absorbing the dirt on the floor.

[0043] When the stains on the ground are mostly liquid, the liquid sucked in by the robot exists in the separation box. When the amount of water sucked in is too much and the water in the separation box covers the buoyancy ball, the buoyancy ball floats up under the buoyancy of the liquid, and the top block 24 moves up, thereby driving the windshield component 3 to drive the push plate to move toward the air outlet, increasing the resistance of the air outlet and thus reducing the wind force; when there is less liquid in the separation box, the buoyancy ball has no buoyancy effect, and the filter plate 23 is only affected by gravity under the action of part of the liquid and other impurities in the liquid, driving the push plate to move away from the air outlet, thereby increasing the air volume and increasing the amount of water sucked in.

[0044] The cleaning robot automatically adjusts the push plate at the fan inlet according to the size of the air outlet and the weight of the dust settled on the filter plate 23, thereby automatically adjusting the air volume. There is no need to adjust the gear size, and the air volume is rationally utilized: the more impurity particles accumulated on the filter plate 23, the greater the gravity of the filter plate 23, thereby driving the buoyancy ball to move downward, and the buoyancy ball simultaneously drives the top block 24 downward. The downward movement process drives the baffle 32 away from the air outlet, reducing the resistance of the air outlet. If the air volume is too large, the buoyancy of the buoyancy ball increases, and the buoyancy ball drives the top seat upward. The upward movement process drives the baffle 32 toward the fan, increasing the resistance at the air outlet, thereby reducing the amount of air suction; similarly, if the air volume is too small, the buoyancy of the buoyancy ball decreases, and the buoyancy ball drives the top seat downward. The downward movement process drives the baffle 32 away from the air outlet, reducing the resistance at the air outlet, thereby increasing the amount of air suction. The present invention no longer requires automatic gear shifting of the machine, thus achieving adaptive stepless speed regulation, reducing sensor costs and thus reducing the production cost of the device.
