Description

Technical Field

[0001] This application relates to the field of cleaning equipment technology, specifically to a cleaning robot and its application, including a dust collection box, a base station, and a cleaning system. Background Technology

[0002] Cleaning robots, especially large ones used in commercial environments, are widely used because they can perform cleaning tasks such as washing, mopping, and sweeping, providing users with significant convenience. Cleaning robots are typically equipped with a dust collection box to store the waste they collect; this box needs to be emptied regularly.

[0003] Dust collection boxes are mainly divided into open-type dust collection boxes and closed-type dust collection boxes. Currently, there are relatively mature automatic cleaning solutions for closed-type dust collection boxes, but there are no mature automatic cleaning solutions for open-type dust collection boxes, which means that open-type dust collection boxes often require manual cleaning by users. Summary of the Invention

[0004] This application provides a cleaning robot and its application, including a dust collection box, a base station, and a cleaning system, which facilitates the automatic cleaning of open-type dust collection boxes.

[0005] This application provides a dust collection box for a cleaning robot. The dust collection box includes: a dust collection box body having a receiving cavity, a dust collection port, and a dust removal port; and a cover plate disposed in the receiving cavity, with a dust collection cavity on the side of the cover plate facing the dust removal port; wherein the cover plate can switch between a first state and a second state; when the dust collection box is in the dust collection state, the cover plate is in the first state, and the garbage collected by the cleaning robot enters the dust collection cavity through the dust collection port; when the dust collection box is in the dust removal state, the cover plate is in the second state, which increases the sealing of the dust collection cavity, and the garbage in the dust collection cavity is discharged through the dust removal port.

[0006] In one embodiment of this application, the dust collection port and the dust removal port are arranged sequentially along a set direction, and the cover plate can move along the set direction in the accommodating cavity; wherein, when the cover plate is in a first state, the cover plate moves to a first position, so that the dust collection cavity is connected to the dust collection port; when the cover plate is in a second state, the cover plate moves to a second position, and the second position is closer to the dust removal port than the first position.

[0007] In one embodiment of this application, in a set direction, the second position is located on the side of the dust collection port facing the dust removal port.

[0008] In one embodiment of this application, the dust collection box further includes: a first guide member disposed on the main body of the dust collection box; and a second guide member disposed on the cover plate, the first guide member and the second guide member being used to cooperate in guiding the cover plate to move in a set direction.

[0009] In one embodiment of this application, the first guide is a groove extending in a set direction, and the second guide is a slide rod, which is embedded in the groove and can move along the groove.

[0010] In one embodiment of this application, the dust collection box further includes: a first driving component, which is connected to the cover plate for driving the cover plate to move.

[0011] In one embodiment of this application, the first driving component includes: a push rod disposed on the dust collection box body and capable of moving in a set direction; a steering member disposed on the dust collection box body; and a pull rope, one end of which is connected to a cover plate and the other end of which passes around the steering member and is connected to the push rod; wherein, when the push rod moves in a direction away from the dust collection port, the push rod pulls the cover plate toward the dust collection port via the pull rope, causing the cover plate to move to a second position; when the push rod moves toward the dust collection port, the cover plate moves in a direction away from the dust collection port to a first position.

[0012] In one embodiment of this application, the dust collection box further includes: an elastic member connecting the cover plate for driving the cover plate to move from the second position to the first position.

[0013] Accordingly, this application also provides a base station for a cleaning robot. The cleaning robot has a dust collection box, which includes: a dust collection box body having a receiving cavity, a dust collection port, and a dust removal port; and a cover plate disposed in the receiving cavity, with a dust collection chamber on the side of the cover plate facing the dust removal port; wherein the cover plate can switch between a first state and a second state; when the dust collection box is in the dust collection state, the cover plate is in the first state, and the waste collected by the cleaning robot enters the dust collection chamber through the dust collection port; when the dust collection box is in the dust removal state, the cover plate is in the second state, increasing the sealing of the dust collection chamber, and the waste in the dust collection chamber is discharged through the dust removal port. The base station includes: a base station body; and a second driving component disposed in the base station body, at least for driving the cover plate to switch between the first and second states.

[0014] In one embodiment of this application, the dust collection port and the dust removal port are arranged sequentially along a set direction, and the cover plate can move along the set direction in the accommodating cavity; when the cover plate is in a first state, the cover plate moves to a first position, so that the dust collection cavity is connected to the dust collection port; when the cover plate is in a second state, the cover plate moves to a second position, and the second position is closer to the dust removal port than the first position; the second driving component includes: a driving member; a first cam, which is drivenly connected to the driving member and can drively cooperate with the cover plate, and the driving member drives the cover plate to move to the second position through the first cam.

[0015] In one embodiment of this application, the base station further includes: a storage box disposed on the base station body; a fan connected to the storage box; and an air duct connected at one end to the storage box and provided with a dust suction port at the other end. The dust suction port is retractably disposed on the base station body. When the dust collection box is in the dust removal state, the dust suction port extends relative to the base station body and connects with the dust removal port, and the fan sucks the garbage in the dust collection chamber into the storage box.

[0016] In one embodiment of this application, the second driving component includes: a driving member; and a second cam, which is pulsatorically connected to the driving member and pulsatorically engaged with the vacuuming interface, wherein the driving member drives the vacuuming interface to extend via the second cam.

[0017] In one embodiment of this application, the second driving component further includes: a first cam, which is connected to the driving member and can be driven to cooperate with the cover plate, wherein the driving member drives the cover plate to switch between a first state and a second state through the first cam; wherein the first cam and the second cam can rotate synchronously.

[0018] Accordingly, this application also provides a cleaning robot. The cleaning robot has a dust collection box; the dust collection box includes: a dust collection box body having a receiving cavity, a dust collection port, and a dust removal port; and a cover plate disposed in the receiving cavity, with a dust collection chamber on the side of the cover plate facing the dust removal port; wherein the cover plate can switch between a first state and a second state; when the dust collection box is in the dust collection state, the cover plate is in the first state, and the garbage collected by the cleaning robot enters the dust collection chamber through the dust collection port; when the dust collection box is in the dust removal state, the cover plate is in the second state, increasing the sealing of the dust collection chamber, and the garbage in the dust collection chamber is discharged through the dust removal port.

[0019] Accordingly, this application also provides a cleaning system, including a cleaning robot and a base station; the cleaning robot has a dust collection box, the dust collection box including: a dust collection box body having a receiving cavity, a dust collection port and a dust removal port; and a cover plate disposed in the receiving cavity, and the side of the cover plate facing the dust removal port has a dust collection chamber; wherein, the cover plate can switch between a first state and a second state; when the dust collection box is in the dust collection state, the cover plate is in the first state, and the garbage collected by the cleaning robot enters the dust collection chamber through the dust collection port; when the dust collection box is in the dust removal state, the cover plate is in the second state, which increases the sealing of the dust collection chamber, and the garbage in the dust collection chamber is discharged through the dust removal port; the base station includes: a base station body; and a second driving component disposed in the base station body, at least for driving the cover plate to switch between the first state and the second state.

[0020] The beneficial effects of this application are as follows: Unlike existing technologies, this application provides a cleaning robot and its application, including a dust collection box, a base station, and a cleaning system. The cover of the dust collection box can switch between a first state and a second state. When the dust collection box is in the dust collection state, the cover is in the first state, and the waste collected by the cleaning robot enters the dust collection chamber through the dust collection port. When the dust collection box is in the dust removal state, the cover is in the second state, increasing the sealing of the dust collection chamber, and the waste in the dust collection chamber is discharged through the dust removal port. In other words, by switching the cover to the second state, this application increases the sealing of the dust collection chamber, meaning that the dust collection box has sufficient sealing to allow for cleaning of the waste in the dust collection box using a fan suction method. Especially for the case where the dust collection box of this application is an open-type dust collection box, switching the cover to the second state allows the dust collection box to be automatically cleaned using a fan suction method, thus facilitating the automatic cleaning of open-type dust collection boxes.

Detailed Implementation

[0037] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application. In addition, it should be understood that the specific embodiments described herein are only for illustration and explanation of this application and are not intended to limit this application. In this application, unless otherwise stated, directional terms such as "up," "down," "left," and "right" generally refer to up, down, left, and right in the actual use or working state of the device, specifically the drawing directions in the accompanying drawings.

[0038] This application provides a cleaning robot and its application, including a dust collection box, a base station, and a cleaning system, which are described in detail below. It should be noted that the order of description of the following embodiments is not intended to limit the preferred order of the embodiments of this application. Furthermore, in the following embodiments, the descriptions of each embodiment have their own emphasis; parts not described in detail in a certain embodiment can be referred to in the relevant descriptions of other embodiments.

[0039] In existing technologies, the dust collection boxes of cleaning robots require periodic cleaning. Currently, automated cleaning solutions for enclosed dust collection boxes are relatively mature, such as using a fan to extract the debris. However, there are no mature automated cleaning solutions for open dust collection boxes. The main reasons are: 1. Open dust collection boxes have poor sealing, making automated cleaning via fan suction impossible; 2. The dust collection box is generally located at the bottom of the cleaning robot, resulting in limited operating space between the dust collection box and the base station, making it difficult to automatically clean the dust collection box using methods other than fan suction; 3. When the cleaning robot returns to the base station, the dust collection box is often located at the base station entrance, making it difficult to deploy appropriate equipment for automated cleaning. These factors mean that current open dust collection boxes often require manual cleaning by the user.

[0040] Manually cleaning the dustbin has several drawbacks: 1. The dustbin is usually located at the bottom of the cleaning robot, requiring users to bend down to clean it. The limited space between the dustbin and the base station makes cleaning inconvenient and inefficient. 2. Bacteria can grow inside the dustbin, resulting in a poor user experience and requiring close contact with the dustbin, leading to hygiene issues. 3. Manual dustbin cleaning implies low automation and a lack of technological sophistication.

[0041] In view of this, embodiments of this application provide a cleaning robot and its application, including a dust collection box, a base station, and a cleaning system, which can solve the aforementioned technical problems existing in the prior art. The details are described below.

[0042] Please see Figure 1 , Figure 1 This is a structural schematic diagram of an embodiment of the cleaning robot of this application.

[0043] In one embodiment, the cleaning robot 10 may have cleaning functions such as washing, mopping, and wiping. The cleaning robot 10 can automatically move over surfaces to be cleaned, removing dust and cleaning the surfaces it passes over. The surfaces to be cleaned can be the ground or the surface of an object. Specifically, the cleaning robot 10 has a dust collection box 20, which is used to store the waste collected by the cleaning robot 10 during the cleaning process. The dust collection box 20 needs to be emptied periodically.

[0044] The dust collection box 20 of the present application embodiment will be described in detail below.

[0045] Please refer to the following: Figures 2 to 6 , Figure 2 This is a schematic diagram of the structure of one embodiment of the dust collection box of the cleaning robot of this application. Figure 3 This is a schematic diagram of another embodiment of the dust collection box of the cleaning robot of this application. Figure 4 yes Figure 3 The diagram shows the exploded structure of the dust collection box. Figure 5 yes Figure 2 The diagram shows another state of the dust collection box. Figure 6 yes Figure 3 The diagram shows another state of the dust collection box.

[0046] In one embodiment, the dust collection box 20 includes a dust collection box body 21. The dust collection box body 21 is the main component of the dust collection box 20 used for storing waste. Specifically, the dust collection box body 21 has a receiving cavity 211 for storing waste collected by the cleaning robot 10 during the cleaning process. The dust collection box body 21 also has a dust collection port 212 and a dust removal port 213, which are respectively connected to the receiving cavity 211. When the dust collection box 20 is in the dust collection state, the waste collected by the cleaning robot 10 enters the receiving cavity 211 through the dust collection port 212 and is stored in the receiving cavity 211; when the dust collection box 20 is in the dust removal state, the waste in the receiving cavity 211 is discharged through the dust removal port 213.

[0047] The dust collection box 20 also includes a cover plate 22. The cover plate 22 is disposed in the receiving cavity 211. The side of the cover plate 22 facing the dust removal port 213 has a dust collection cavity 221, which is specifically used to store the waste collected by the cleaning robot 10 during the cleaning process. The cover plate 22 can switch between a first state and a second state. When the dust collection box 20 is in the dust collection state, the cover plate 22 is in the first state, and the waste collected by the cleaning robot 10 enters the dust collection cavity 221 through the dust collection port 212; when the dust collection box 20 is in the dust removal state, the cover plate 22 is in the second state, which increases the sealing of the dust collection cavity 221, and the waste in the dust collection cavity 221 is discharged through the dust removal port 213.

[0048] In this embodiment, by switching to the second state via the cover plate 22, the sealing degree of the dust collection chamber 221 is increased. This means that the dust collection box 20 has sufficient sealing, allowing for the cleaning of debris using a fan suction method (described in detail below). Especially for the case where the dust collection box 20 is an open-type dust collection box, switching to the second state via the cover plate 22 is equivalent to transforming the open-type dust collection box into a closed-type dust collection box, allowing for automatic cleaning of the dust collection box 20 using a fan suction method. This facilitates the automatic cleaning of open-type dust collection boxes. The dust collection box 20 in this embodiment can utilize a mature automatic cleaning solution to achieve automatic cleaning of the dust collection box 20, eliminating the need for manual cleaning by the user. This completely solves the problems of poor operability, low efficiency, and poor hygiene caused by manual cleaning of the dust collection box 20, and also improves the automation level and technological sophistication of the system, including the cleaning robot 10, in this embodiment.

[0049] It should be noted that the sealing degree of the dust collection chamber 221 should be understood as the degree of sealing of the dust collection chamber 221. The greater the sealing degree of the dust collection chamber 221, the higher the degree of sealing of the dust collection chamber 221, which is beneficial to ensure that the dust collection chamber 221 has sufficient negative pressure when the dust collection box 20 is in the dust removal state, so that the garbage in the dust collection box 20 can be collected back by the fan.

[0050] In one embodiment, the dust collection port 212 and the dust removal port 213 are aligned in a predetermined direction (e.g., Figure 2 As indicated by the middle arrow X (the same applies below), the cover plate 22 is arranged sequentially and can move along a set direction within the receiving cavity 211. When the cover plate 22 is in the first state, it moves to the first position S1, causing the dust collection cavity 221 to connect with the dust collection port 212, as shown below. Figure 2 and Figure 3 As shown; when the cover plate 22 is in the second state, the cover plate 22 moves to the second position S2, as... Figure 5 and Figure 6 As shown. In this case, the second position S2 is closer to the dust collection port 213 than the first position S1. Thus, the cover plate 22 moves from the first position S1 to the second position S2, which can increase the sealing degree of the dust collection chamber 221.

[0051] Specifically, when the dust collection box 20 is in the dust collection state, the cover plate 22 moves to the first position S1 to switch to the first state, so that the dust collection chamber 221 is connected to the dust collection port 212. At this time, the degree of connection between the dust collection port 212 and the dust collection chamber 221 is relatively high, so that the garbage collected by the cleaning robot 10 can enter the dust collection chamber 221 through the dust collection port 212. Figure 2 and Figure 3As shown. When the dust collection box 20 is in the dust removal state, the cover plate 22 moves from the first position S1 to the second position S2 to switch to the second state. At this time, the connection between the dust collection port 212 and the dust collection chamber 221 is reduced, which increases the sealing of the dust collection chamber 221. The garbage in the dust collection chamber 221 is discharged through the dust removal port 213, achieving the purpose of cleaning the dust collection box 20. Figure 5 and Figure 6 As shown. After the dust collection box 20 is cleaned, the cover plate 22 moves back from the second position S2 to the first position S1, that is, switches back to the first state to ensure that the dust collection box 20 can collect dust normally.

[0052] Furthermore, such as Figure 2 and Figure 5 As shown, in the set direction, the second position S2 is located on the side of the dust collection port 212 facing the dust removal port 213. During normal use of the cleaning robot 10, the set direction is vertical, meaning the height of the second position S2 is lower than the height of the dust collection port 212. When the cover plate 22 moves to the second position S2, the cover plate 22 moves below the dust collection port 212, minimizing the connection between the dust collection port 212 and the dust collection chamber 221, thus maximizing the sealing of the dust collection chamber 221 to ensure sufficient negative pressure in the dust collection chamber 221 during subsequent dust removal.

[0053] Of course, in other embodiments of this application, the second position S2 is not limited to being located on the side of the dust collection port 212 facing the dust removal port 213. The cover plate 22 can move from the first position S1 toward the dust removal port 213 to increase the sealing degree of the dust collection chamber 221, which is not limited here. Furthermore, in other embodiments of this application, the cover plate 22 is not limited to the design that allows it to move in a set direction in the accommodating cavity 211 as described above. For example, the cover plate 22 can be rotatable. When the cover plate 22 is in the first state, the cover plate 22 rotates away from the dust collection port 212 so that the dust collection box 20 can collect dust normally. When the cover plate 22 is in the second state, the cover plate 22 rotates toward the dust collection port 212 to close the dust collection port 212, thereby increasing the sealing degree of the dust collection chamber 221. Furthermore, the cover plate 22 can be positioned at the dust collection port 212, and the sealing degree of the cover plate 22 itself can be adjusted to selectively close the dust collection port 212. When the cover plate 22 is in the first state, the dust collection port 212 is open, and when the cover plate 22 is in the second state, the dust collection port 212 is closed. This is not a limitation. The embodiments of this application are described using the example of the cover plate 22 being able to move along a set direction in the receiving cavity 211, which is only for the purpose of discussion and is not intended to limit the scope of the application.

[0054] Please continue reading. Figure 4In one embodiment, the dust collection box 20 further includes a first guide 214 and a second guide 222. The first guide 214 is disposed on the dust collection box body 21, and the second guide 222 is disposed on the cover plate 22. The first guide 214 and the second guide 222 are used to cooperate in guiding the cover plate 22 to move in a predetermined direction.

[0055] Specifically, the first guide 214 is a groove extending in a set direction, and the second guide 222 is a slide rod, which is embedded in the groove and can move along the groove. When the cover plate 22 switches between the first state and the second state, the cover plate 22 moves between the first position S1 and the second position S2. At this time, the slide rod moves along the groove to guide the cover plate 22 to move.

[0056] Furthermore, the dust collection box 20 also includes a transmission component 223 and a first drive assembly 23. The transmission component 223 is located at the end of the second guide 222 away from the cover plate 22. The first drive assembly 23 is drively connected to the transmission component 223 to drive the cover plate 22 to move via the transmission component 223. The first drive assembly 23 will be described in detail below. When the dust collection box 20 is in the dust removal state, the first drive assembly 23 drives the cover plate 22 to move from the first position S1 to the second position S2 via the transmission component 223 to switch to the second state. At this time, the degree of communication between the dust collection port 212 and the dust collection chamber 221 is reduced, which increases the sealing degree of the dust collection chamber 221, and the garbage in the dust collection chamber 221 is discharged through the dust removal port 213.

[0057] It should be noted that in other embodiments of this application, the first guide 214 and the second guide 222 are not limited to the above-mentioned sliding groove and sliding rod cooperation. The first guide 214 and the second guide 222 can also adopt the form of sliding rail and slider cooperation, for example, the dust collection box body 21 is provided with a sliding rail extending in a set direction on the side facing the cover plate 22, and the cover plate 22 is provided with a slider, which is slidably connected to the sliding rail. The slider moves along the sliding rail to guide the cover plate 22 to move. This is not limited here.

[0058] Please refer to the following: Figure 7 and Figure 8 , Figure 7 yes Figure 2 A partial structural diagram of the dust collection box is shown. Figure 8 yes Figure 7 The diagram shows another state of the dust collection box.

[0059] In one embodiment, the first driving component 23 is driven to the cover plate 22. Specifically, the first driving component 23 can be driven to the cover plate 22 via a transmission component 223. The first driving component 23 is used to drive the cover plate 22 to move. Specifically, the first driving component 23 is used to drive the cover plate 22 to move from the first position S1 to the second position S2, so that the cover plate 22 switches to the second state.

[0060] Specifically, the first drive assembly 23 includes a push rod 231, a steering component 232, and a pull rope 233. The push rod 231 is located on the dust collection box body 21 and can move in a set direction. The steering component 232 is located on the dust collection box body 21. One end of the pull rope 233 is connected to the cover plate 22, and the other end passes around the steering component 232 and connects to the push rod 231. When the push rod 231 moves away from the dust collection port 213, the push rod 231 pulls the cover plate 22 towards the dust collection port 213 via the pull rope 233, causing the cover plate 22 to move to the second position S2; when the push rod 231 moves towards the dust collection port 213, the cover plate 22 moves away from the dust collection port 213 to the first position S1.

[0061] When the dust collection box 20 is in dust removal mode, the push rod 231 moves away from the dust collection port 213. The push rod 231 pulls the cover plate 22 towards the dust collection port 213 via the pull rope 233, causing the cover plate 22 to move from the first position S1 to the second position S2, switching to the second state. At this time, the connection between the dust collection port 212 and the dust collection chamber 221 decreases, the sealing of the dust collection chamber 221 increases, and the waste in the dust collection chamber 221 is discharged through the dust collection port 213. Figure 8 As shown. When the dust collection box 20 returns to the dust collection state, the push rod 231 moves towards the dust collection port 213, and the cover plate 22 moves from the second position S2 to the first position S1 in a direction away from the dust collection port 213, that is, the cover plate 22 switches back to the first state, ensuring that the dust collection box 20 can collect dust normally, as shown. Figure 7 As shown.

[0062] It should be noted that, considering the limited space on the dust collection box body 21, this embodiment uses a steering component 232 to reverse the driving force provided by the push rod 231 and apply it to the cover plate 22. This greatly increases the travel distance of the push rod 231 in the set direction, ensuring that the cover plate 22 has sufficient travel distance in the set direction. This helps ensure that when the dust collection box 20 is in the dust removal state, the cover plate 22 can move to below the dust collection port 212, thereby ensuring that the dust collection chamber 221 has sufficient sealing. Furthermore, the steering component 232 can be a fixed pulley or the like. This not only enables the driving force provided by the push rod 231 to reverse and apply it to the cover plate 22, but also reduces the frictional resistance experienced by the pull rope 233. This facilitates the smooth movement of the cover plate 22 by the push rod 231 and reduces the risk of damage to the pull rope 233 due to wear.

[0063] Of course, in other embodiments of this application, the first drive assembly 23 may not be provided with a steering component 232, and the push rod 231 and the cover plate 22 may move synchronously in the same direction, which is not limited here.

[0064] In one embodiment, the dust collection box 20 further includes an elastic element 24. The elastic element 24 is connected to the cover plate 22 and is used to drive the cover plate 22 to move from the second position S2 to the first position S1. In other words, this embodiment uses the elastic element 24 to drive the cover plate 22 to reset after the dust collection box 20 is cleaned. Of course, in other embodiments of this application, the first driving component 23 can also be used to drive the cover plate 22 to move from the second position S2 to the first position S1, that is, to drive the cover plate 22 to reset. The first driving component 23 can be adapted to add corresponding components for driving the cover plate 22 to reset, which is not limited here. The embodiments of this application use the example of driving the cover plate 22 to reset via the elastic element 24 for illustration only, and are not intended to limit the scope of the application.

[0065] Specifically, the elastic element 24 can be a compression spring. One end of the elastic element 24 is connected to the cover plate 22, and the other end is connected to the side of the dust collection box body 21 near the dust removal port 213. When the dust collection box 20 is in the dust removal state, the cover plate 22 moves from the first position S1 to the second position S2 to switch to the second state. At this time, the cover plate 22 compresses the elastic element 24. After the dust collection box 20 is cleaned, under the elastic restoring force provided by the elastic element 24, the cover plate 22 moves back from the second position S2 to the first position S1 and switches back to the first state.

[0066] Of course, in other embodiments of this application, the elastic element 24 can also be a tension spring. In this case, the setting position of the elastic element 24 needs to be adjusted accordingly. For example, one end of the elastic element 24 is connected to the cover plate 22, and the other end is connected to the side of the dust collection box body 21 away from the dust removal port 213. This is not limited here.

[0067] Please continue reading. Figure 2 and Figure 5 In one embodiment, the dust collection box 20 further includes a door 25. The door 25 is rotatably disposed on the dust collection box body 21 and is capable of closing or opening the dust collection port 213. When the dust collection box 20 is in the dust collection state, the door 25 closes the dust collection port 213 to prevent debris in the dust collection chamber 221 from leaking through the dust collection port 213, such as... Figure 2 As shown; when the dust collection box 20 is in the dust removal state, the door 25 opens the dust removal port 213 to allow the garbage in the dust collection chamber 221 to be discharged through the dust removal port 213, thereby achieving the purpose of cleaning the dust collection box 20, as shown. Figure 5 As shown.

[0068] Regarding the use of a fan to clean the dust collection box 20, when the dust collection box 20 is in dust removal mode, the fan suction creates a negative pressure environment in the dust collection chamber 221. At least because the dust collection box body 21 has a sliding groove and the cover plate 22 is not completely sealed to the dust collection box body 21, the dust collection chamber 221 is not completely sealed. Under the pressure difference between the dust collection chamber 221 and the external environment, the door 25 rotates away from the cover plate 22, opening the dust removal port 213.

[0069] Furthermore, the door 25 is configured to allow the self-sealing dust collection port 213 to rotate away from the cover plate 22, but not to rotate towards the cover plate 22. This prevents the door 25 from rotating towards the cover plate 22 under the pressure difference between the dust collection chamber 221 and the external environment, which would otherwise cause the door 25 to rotate into the dust collection chamber 221 from the self-sealing dust collection port 213. In this case, the door 25 would easily affect the discharge of garbage from the dust collection chamber 221 through the dust collection port 213.

[0070] Please refer to the following: Figure 9 , Figure 9 This is a schematic diagram of the structure of a base station of the cleaning robot of this application. Figure 9 The cleaning robot 10, which is paired with the base station 30, is shown in the dashed line in the middle.

[0071] In one embodiment, the cleaning robot 10 is equipped with a base station 30, which assists the cleaning robot 10 in performing daily cleaning tasks. Specifically, in this embodiment, the base station 30 is used to clean the dust collection box 20 of the cleaning robot 10. When the cleaning robot 10 enters the base station 30 and reaches a set position, the base station 30 opens the dust collection box 20, allowing the debris in the dust collection box 20 to be cleaned through the base station 30.

[0072] Specifically, the base station 30 includes a base station body 31. As the name suggests, the base station body 31 is the main body of the base station 30 and houses all the components required for the base station 30, including the components required for cleaning the dust collection box 20.

[0073] The base station 30 also includes a second driving component 32. The second driving component 32 is disposed on the base station body 31, and the second driving component 32 is at least used to drive the cover plate 22 to switch between a first state and a second state. When the dust collection box 20 is in the dust collection state, the cover plate 22 switches to the first state, and the garbage collected by the cleaning robot 10 enters the dust collection chamber 221 through the dust collection port 212; when the dust collection box 20 is in the dust removal state, the second driving component 32 drives the cover plate 22 to switch to the second state, thereby increasing the sealing of the dust collection chamber 221, and the garbage in the dust collection chamber 221 is discharged through the dust removal port 213.

[0074] Specifically, when the dust collection box 20 is in the dust collection state, the cover plate 22 moves to the first position S1 to switch to the first state, making the dust collection chamber 221 connected to the dust collection port 212. At this time, the degree of connection between the dust collection port 212 and the dust collection chamber 221 is relatively high, allowing the garbage collected by the cleaning robot 10 to enter the dust collection chamber 221 through the dust collection port 212. When the dust collection box 20 is in the dust removal state, the second drive component 32 drives the cover plate 22 to move from the first position S1 to the second position S2 to switch to the second state. At this time, the degree of connection between the dust collection port 212 and the dust collection chamber 221 is reduced, increasing the sealing degree of the dust collection chamber 221. The garbage in the dust collection chamber 221 is discharged through the dust removal port 213, achieving the purpose of cleaning the dust collection box 20. After the dust collection box 20 is cleaned, the cover plate 22 moves back from the second position S2 to the first position S1, that is, switches back to the first state, ensuring that the dust collection box 20 can collect dust normally.

[0075] Please refer to the following: Figures 10 to 13 , Figure 10 This is a schematic diagram of a previous embodiment before the dust collection box and the vacuum interface were connected. Figure 11 This is a schematic diagram of one embodiment of the dust collection box and the vacuum interface after they are connected. Figure 12 This is a schematic diagram of a structure of an embodiment before the second driving component drives the cover plate to switch to the second state. Figure 13 This is a schematic diagram of the structure of one embodiment after the second driving component of this application drives the cover plate to switch to the second state.

[0076] In one embodiment, the second drive assembly 32 includes a drive member 321. The drive member 321 is the power source for the second drive assembly 32 and provides driving force to drive the cover plate 22 to switch between a first state and a second state.

[0077] In this embodiment, the cover plate 22 moves between a first position S1 and a second position S2 to switch between a first state and a second state. The second drive assembly 32 further includes a first cam 322. The first cam 322 is connected to the drive member 321 and can engage with the cover plate 22. The drive member 321 drives the first cam 322 to rotate, causing the first cam 322 to move the cover plate 22 to the second position S2. At this point, the cover plate 22 moves from the first position S1 to the second position S2, meaning the cover plate 22 switches to the second state.

[0078] Specifically, when the dust collection box 20 is in the dust collection state, the cover plate 22 moves to the first position S1 to switch to the first state, so that the dust collection chamber 221 is connected to the dust collection port 212. At this time, the degree of connection between the dust collection port 212 and the dust collection chamber 221 is relatively high, so that the garbage collected by the cleaning robot 10 can enter the dust collection chamber 221 through the dust collection port 212. Figure 10 As shown. When the dust collection box 20 is in the dust removal state, the drive unit 321 drives the cover plate 22 to move to the second position S2 via the first cam 322, so that the cover plate 22 moves from the first position S1 to the second position S2 to switch to the second state. At this time, the degree of communication between the dust collection port 212 and the dust collection chamber 221 decreases, the sealing degree of the dust collection chamber 221 increases, and the garbage in the dust collection chamber 221 is discharged through the dust removal port 213, such as... Figure 11 As shown. After the dust collection box 20 is cleaned, the cover plate 22 moves back from the second position S2 to the first position S1, that is, switches back to the first state to ensure that the dust collection box 20 can collect dust normally.

[0079] For example, such as Figure 12 and Figure 13 As shown, the first cam 322 can be an eccentric wheel, meaning the outer circumferential contour of the first cam 322 is an arc, but the axis of rotation of the first cam 322 does not pass through the center of the first cam 322. The first cam 322 has a first cam surface 3221, which is the area on the outer circumferential surface of the first cam 322 that is away from its axis of rotation. The driving member 321 drives the first cam 322 to rotate around its axis of rotation, so that the first cam surface 3221 rotates with the first cam 322 until it contacts the push rod 231 on the dust collection box body 21. As the first cam 322 rotates further, the first cam 322 drives the push rod 231 to move away from the dust collection port 213 through the first cam surface 3221. The push rod 231 pulls the cover plate 22 towards the dust collection port 213 through the pull rope 233, so that the cover plate 22 moves from the first position S1 to the second position S2. When the first cam surface 3221 rotates away from the push rod 231 along with the first cam 322, the cover plate 22 moves from the second position S2 to the first position S1 in the direction away from the dust removal port 213 under the action of the elastic restoring force provided by the elastic element 24, and the push rod 231 also moves towards the dust removal port 213, so as to realize the reset of the cover plate 22.

[0080] Of course, in other embodiments of this application, the first cam 322 is not limited to an eccentric wheel. For example, the outline of the outer peripheral surface of the first cam 322 may not be a circular arc, but an irregular arc, which is not limited here.

[0081] In one embodiment, the base station 30 further includes a collection box 33, a fan 34, and an air duct 35. The collection box 33 is located on the base station body 31 and is used to collect the waste collected by the base station 30 from the dust collection box 20 of the cleaning robot 10. The fan 34 is connected to the collection box 33. One end of the air duct 35 is connected to the collection box 33, and the other end is provided with a suction port 36. In other words, this embodiment uses the fan 34 to collect the waste in the dust collection box 20 by suction. The operation of the fan 34 creates a negative pressure environment inside the collection box 33, the air duct 35, and the dust collection box 20. Under the action of the internal and external pressure difference, the waste in the dust collection box 20 is transported to the collection box 33 through the air duct 35, completing the waste collection in the dust collection box 20.

[0082] The suction port 36 is retractably located on the base station body 31. When the dust collection box 20 is in dust removal mode, the suction port 36 extends relative to the base station body 31 and connects with the dust removal port 213. At this time, there is sufficient sealing between the suction port 36 and the dust removal port 213, and the fan 34 sucks the debris in the dust collection chamber 221 into the storage box 33. Specifically, during the cleaning operation of the cleaning robot 10, the dust collection box 20 is in dust collection mode, and the cleaning robot 10 has not returned to the base station 30. After the cleaning robot 10 completes its cleaning work, it returns to the base station 30. The suction port 36 extends relative to the base station body 31 and connects with the dust removal port 213. At this time, the dust collection box 20 is in dust removal mode. The fan 34 operates, creating a negative pressure environment inside the storage box 33, the air duct 35, and the dust collection box 20. Under the action of the internal and external pressure difference, the waste in the dust collection box 20 is transported through the suction port 36 to the air duct 35, and then through the air duct 35 to the storage box 33, completing the waste collection in the dust collection box 20. After the dust collection box 20 is cleaned, the suction port 36 retracts into the base station body 31 and separates from the dust removal port 213.

[0083] Furthermore, the air duct 35 includes an air duct body 351 and a corrugated pipe 352. One end of the air duct body 351 is connected to the storage box 33, and the other end is connected to the corrugated pipe 352. The end of the corrugated pipe 352 away from the air duct body 351 is connected to the dust suction port 36. The corrugated pipe 352 is telescopic, specifically, the wall of the corrugated pipe 352 is pleated, so that the dust suction port 36 can extend or retract relative to the base station body 31.

[0084] In one embodiment, the second drive assembly 32 is used not only to drive the cover plate 22 to switch between a first state and a second state, but also to drive the vacuum port 36 to extend relative to the base station body 31 to dock with the dust removal port 213. The second drive assembly 32 includes a drive member 321 and a second cam 323. The second cam 323 is pulsatorically connected to the drive member 321, and the second cam 323 can pulsatorically engage with the vacuum port 36, so that the drive member 321 drives the vacuum port 36 to extend through the second cam 323.

[0085] Specifically, after the cleaning robot 10 completes its cleaning work, it returns to the base station 30. The drive unit 321, via the second cam 323, causes the suction port 36 to extend relative to the base station body 31 and connect with the dust removal port 213. At this time, the dust collection box 20 is in dust removal mode. The fan 34 operates, creating a negative pressure environment inside the storage box 33, the air duct 35, and the dust collection box 20. Under the action of the internal and external pressure difference, the waste in the dust collection box 20 is transported through the suction port 36 to the air duct 35, and then through the air duct 35 to the storage box 33, completing the waste recycling in the dust collection box 20. Figure 11 The dashed arrow indicates the direction of waste collection. After the dust collection box 20 has finished cleaning, the suction port 36 retracts into the base station body 31 and separates from the dust removal port 213, as shown. Figure 10 As shown.

[0086] For example, the second cam 323 can be an eccentric wheel, meaning its outer peripheral surface is an arc, but its axis of rotation does not pass through its center. The second cam 323 has a second cam surface 3231, which is the area on its outer peripheral surface away from its axis of rotation. The drive member 321 drives the second cam 323 to rotate around its axis of rotation, causing the second cam surface 3231 to rotate with the second cam 323 until it contacts the suction port 36. As the second cam 323 rotates further, it causes the suction port 36 to extend relative to the base station body 31 via the second cam surface 3231. When the second cam surface 3231 rotates away from the suction port 36, the suction port 36 retracts into the base station body 31, at least under its own gravity, thus resetting the suction port 36.

[0087] Of course, in other embodiments of this application, the second cam 323 is not limited to an eccentric wheel. For example, the outer contour of the second cam 323 may not be a circular arc, but an irregular arc, which is not limited here. Furthermore, additional components for driving the vacuum port 36 to retract into the base station body 31 may be provided. For example, elastic components such as springs may be provided so that the vacuum port 36 retracts into the base station body 31 under its own weight and the elastic restoring force provided by the spring, which is not limited here.

[0088] In one embodiment, the first cam 322 and the second cam 323 can rotate synchronously. In other words, the second drive assembly 32 synchronously drives the cover plate 22 to switch to the second state and drives the dust suction interface 36 to extend relative to the base station body 31 and dock with the dust removal port 213, so that the state switching process of the cover plate 22 and the docking process of the dust suction interface 36 and the dust removal port 213 are carried out synchronously, which is beneficial to improving the cleaning efficiency of the dust collection box 20.

[0089] Specifically, when the dust collection box 20 is in the dust removal state, the drive unit 321 drives the first cam 322 to move the cover plate 22 to the second position S2 to switch to the second state, and the drive unit 321 simultaneously drives the second cam 323 to extend the suction port 36 relative to the base station body 31 and connect with the dust removal port 213. At this time, the degree of communication between the dust collection port 212 and the dust collection chamber 221 is reduced, the sealing degree of the dust collection chamber 221 is increased, and the garbage in the dust collection chamber 221 is discharged through the dust removal port 213.

[0090] Furthermore, the second drive assembly 32 also includes a timing pulley 324. The drive member 321 is connected to the first cam 322 and the second cam 323 via the timing pulley 324 to drive the first cam 322 and the second cam 323 to rotate synchronously.

[0091] In one embodiment, the cleaning system includes a cleaning robot 10 and a base station 30. The cleaning robot 10 has a dust collection box 20, which includes a dust collection box body 21 and a cover 22. The dust collection box body 21 has a receiving cavity 211, a dust collection port 212, and a dust removal port 213. The cover 22 is disposed in the receiving cavity 211, and the side of the cover 22 facing the dust removal port 213 has a dust collection chamber 221. The cover 22 can switch between a first state and a second state; when the dust collection box 20 is in the dust collection state, the cover 22 is in the first state, and the waste collected by the cleaning robot 10 enters the dust collection chamber 221 through the dust collection port 212; when the dust collection box 20 is in the dust removal state, the cover 22 is in the second state, which increases the sealing of the dust collection chamber 221, and the waste in the dust collection chamber 221 is discharged through the dust removal port 213. The base station 30 includes a base station body 31 and a second drive assembly 32. The second driving component 32 is disposed on the base station body 31 and is used to drive the cover plate 22 to switch between the first state and the second state.

[0092] It should be noted that the cleaning robot 10 and the base station 30 in this embodiment have been described in detail in the above embodiments, and will not be repeated here.

[0093] The technical solutions provided in the embodiments of this application will be described below in conjunction with specific application scenarios.

[0094] Application Scenario 1:

[0095] The dust collection box 20 of the cleaning robot 10 is used to store the waste collected by the cleaning robot 10 during the cleaning process. The dust collection box 20 includes a dust collection box body 21 and a cover plate 22. The dust collection box body 21 has a receiving cavity 211, a dust collection port 212, and a dust removal port 213. The cover plate 22 is disposed in the receiving cavity 211, and the side of the cover plate 22 facing the dust removal port 213 has a dust collection cavity 221. The cover plate 22 can switch between a first state and a second state.

[0096] During the cleaning process of the cleaning robot 10, the dust collection box 20 is in the dust collection state. When the dust collection box 20 is in the dust collection state, the cover plate 22 is in the first position S1, that is, the cover plate 22 is in the first state. At this time, the degree of communication between the dust collection port 212 and the dust collection chamber 221 is relatively high, allowing the garbage collected by the cleaning robot 10 to enter the dust collection chamber 221 through the dust collection port 212. When the dust collection box 20 is in the dust removal state, the cover plate 22 moves from the first position S1 to the second position S2 to switch to the second state. At this time, the degree of communication between the dust collection port 212 and the dust collection chamber 221 decreases, which increases the sealing degree of the dust collection chamber 221. The garbage in the dust collection chamber 221 is discharged through the dust removal port 213, achieving the purpose of cleaning the dust collection box 20. After the dust collection box 20 is cleaned, the cover plate 22 moves back from the second position S2 to the first position S1, that is, switches back to the first state, ensuring that the dust collection box 20 can collect dust normally.

[0097] By switching the cover plate 22 to the second state in the above manner, the sealing degree of the dust collection chamber 221 is increased. This means that the dust collection box 20 has sufficient sealing, and the dust can be cleaned by the suction of the fan 34. Especially for the case where the dust collection box 20 is an open dust collection box, switching the cover plate 22 to the second state is equivalent to transforming the open dust collection box into a closed dust collection box, allowing the dust collection box 20 to be automatically cleaned by the suction of the fan 34, which is beneficial for the automatic cleaning of open dust collection boxes. The dust collection box 20 can use a mature automatic cleaning solution (such as the suction solution of the fan 34) to achieve automatic cleaning of the dust collection box 20, eliminating the need for manual cleaning by the user. This completely solves the problems of poor operability, low efficiency, and poor hygiene caused by manual cleaning of the dust collection box 20, and also helps to improve the automation level and technological feel of the system, including the cleaning robot 10.

[0098] Application Scenario 2:

[0099] The base station 30 of the cleaning robot 10 is used to clean the dust collection box 20 of the cleaning robot 10. The dust collection box 20 includes a dust collection box body 21 and a cover 22. The dust collection box body 21 has a receiving cavity 211, a dust collection port 212, and a dust removal port 213. The cover 22 is disposed in the receiving cavity 211, and the side of the cover 22 facing the dust removal port 213 has a dust collection cavity 221. The cover 22 is capable of switching between a first state and a second state. The base station 30 includes a base station body 31 and a second drive assembly 32. The second drive assembly 32 is disposed in the base station body 31 and is used at least to drive the cover 22 to switch between the first state and the second state.

[0100] During the cleaning operation of the cleaning robot 10, the dust collection box 20 is in the dust collection state. When the dust collection box 20 is in the dust collection state, the cover plate 22 is in the first position S1, that is, the cover plate 22 is in the first state. At this time, the degree of communication between the dust collection port 212 and the dust collection chamber 221 is relatively high, allowing the garbage collected by the cleaning robot 10 to enter the dust collection chamber 221 through the dust collection port 212.

[0101] After the cleaning robot 10 completes its cleaning work, it returns to the base station 30. In response to the cleaning robot 10 entering the base station 30 and reaching the set position, the drive unit 321 drives the first cam 322 to rotate, causing the first cam surface 3221 of the first cam 322 to contact the push rod 231 on the dust collection box body 21. As the drive unit 321 drives the first cam 322 to rotate further, the first cam 322, through the first cam surface 3221, drives the push rod 231 to move away from the dust collection port 213. The push rod 231, through the pull rope 233, pulls the cover plate 22 towards the dust collection port 213, causing the cover plate 22 to move from the first position S1 to the second position S2, i.e., the cover plate 22 switches to the second state. At this time, the connection between the dust collection port 212 and the dust collection chamber 221 decreases, increasing the sealing of the dust collection chamber 221. The drive unit 321 also simultaneously drives the second cam 323 to rotate, causing the second cam surface 3231 of the second cam 323 to contact the suction port 36. As the driving component 321 drives the second cam 323 to rotate further, the second cam 323 drives the dust suction port 36 to extend relative to the base station body 31 through the second cam surface 3231.

[0102] After the dust collection box 20 is cleaned, the drive unit 321 drives the first cam 322 to rotate, so that the first cam surface 3221 of the first cam 322 moves away from the push rod 231. At this time, under the action of the elastic restoring force provided by the elastic member 24, the cover plate 22 moves from the second position S2 to the first position S1 in the direction away from the dust removal port 213, and the push rod 231 also moves towards the dust removal port 213, realizing the reset of the cover plate 22. The drive unit 321 also drives the second cam 323 to rotate, so that the second cam surface 3231 of the second cam 323 moves away from the dust suction port 36, and the dust suction port 36 retracts into the base station body 31 at least under its own gravity, realizing the reset of the dust suction port 36.

[0103] By switching the cover plate 22 to the second state in the above manner, the sealing degree of the dust collection chamber 221 is increased. This means that the dust collection box 20 has sufficient sealing, and the dust can be cleaned by the suction of the fan 34. Especially for the case where the dust collection box 20 is an open dust collection box, switching the cover plate 22 to the second state is equivalent to transforming the open dust collection box into a closed dust collection box, allowing the dust collection box 20 to be automatically cleaned by the suction of the fan 34, which is beneficial for the automatic cleaning of open dust collection boxes. The dust collection box 20 can use a mature automatic cleaning solution (such as the suction solution of the fan 34) to achieve automatic cleaning of the dust collection box 20, eliminating the need for manual cleaning by the user. This completely solves the problems of poor operability, low efficiency, and poor hygiene caused by manual cleaning of the dust collection box 20, and also helps to improve the automation level and technological feel of the system, including the cleaning robot 10.

[0104] Application Scenario 3:

[0105] The cleaning system includes a cleaning robot 10 and a base station 30. The base station 30 is used to clean the dust collection box 20 of the cleaning robot 10. Specifically, when the cleaning robot 10 enters the base station 30 and reaches a set position, the base station 30 opens the dust collection box 20, allowing the debris in the dust collection box 20 to be cleaned through the base station 30. Specifically, the dust collection box 20 includes a dust collection box body 21 and a cover plate 22. The dust collection box body 21 has a receiving cavity 211, a dust collection port 212, and a dust removal port 213. The cover plate 22 is disposed in the receiving cavity 211, and the side of the cover plate 22 facing the dust removal port 213 has a dust collection cavity 221. The cover plate 22 can switch between a first state and a second state. When the dust collection box 20 is in the dust collection state, the cover plate 22 is in the first state, and the garbage collected by the cleaning robot 10 enters the dust collection chamber 221 through the dust collection port 212. When the dust collection box 20 is in the dust removal state, the cover plate 22 is in the second state, which increases the sealing of the dust collection chamber 221, and the garbage in the dust collection chamber 221 is discharged through the dust removal port 213. The base station 30 includes a base station body 31 and a second drive assembly 32. The second drive assembly 32 is located on the base station body 31 and is used at least to drive the cover plate 22 to switch between the first state and the second state.

[0106] During the cleaning operation of the cleaning robot 10, the dust collection box 20 is in the dust collection state. When the dust collection box 20 is in the dust collection state, the cover plate 22 is in the first position S1, that is, the cover plate 22 is in the first state. At this time, the degree of communication between the dust collection port 212 and the dust collection chamber 221 is relatively high, allowing the garbage collected by the cleaning robot 10 to enter the dust collection chamber 221 through the dust collection port 212.

[0107] After the cleaning robot 10 completes its cleaning work, it returns to the base station 30. In response to the cleaning robot 10 entering the base station 30 and reaching the set position, the drive unit 321 drives the first cam 322 to rotate, causing the first cam surface 3221 of the first cam 322 to contact the push rod 231 on the dust collection box body 21. As the drive unit 321 drives the first cam 322 to rotate further, the first cam 322, through the first cam surface 3221, drives the push rod 231 to move away from the dust collection port 213. The push rod 231, through the pull rope 233, pulls the cover plate 22 towards the dust collection port 213, causing the cover plate 22 to move from the first position S1 to the second position S2, i.e., the cover plate 22 switches to the second state. At this time, the connection between the dust collection port 212 and the dust collection chamber 221 decreases, increasing the sealing of the dust collection chamber 221. The drive unit 321 also simultaneously drives the second cam 323 to rotate, causing the second cam surface 3231 of the second cam 323 to contact the suction port 36. As the driving component 321 drives the second cam 323 to rotate further, the second cam 323 drives the dust suction port 36 to extend relative to the base station body 31 through the second cam surface 3231.

[0108] After the dust collection box 20 is cleaned, the drive unit 321 drives the first cam 322 to rotate, so that the first cam surface 3221 of the first cam 322 moves away from the push rod 231. At this time, under the action of the elastic restoring force provided by the elastic member 24, the cover plate 22 moves from the second position S2 to the first position S1 in the direction away from the dust removal port 213, and the push rod 231 also moves towards the dust removal port 213, realizing the reset of the cover plate 22. The drive unit 321 also drives the second cam 323 to rotate, so that the second cam surface 3231 of the second cam 323 moves away from the dust suction port 36, and the dust suction port 36 retracts into the base station body 31 at least under its own gravity, realizing the reset of the dust suction port 36.

[0109] By switching the cover plate 22 to the second state in the above manner, the sealing degree of the dust collection chamber 221 is increased. This means that the dust collection box 20 has sufficient sealing, and the dust can be cleaned by the suction of the fan 34. Especially for the case where the dust collection box 20 is an open dust collection box, switching the cover plate 22 to the second state is equivalent to transforming the open dust collection box into a closed dust collection box, allowing the dust collection box 20 to be automatically cleaned by the suction of the fan 34, which is beneficial for the automatic cleaning of open dust collection boxes. The dust collection box 20 can use a mature automatic cleaning solution (such as the suction solution of the fan 34) to achieve automatic cleaning of the dust collection box 20, eliminating the need for manual cleaning by the user. This completely solves the problems of poor operability, low efficiency, and poor hygiene caused by manual cleaning of the dust collection box 20, and also helps to improve the automation level and technological feel of the system, including the cleaning robot 10.
