Description

Technical Field

[0001] This application belongs to the field of home intelligent device technology, specifically relating to a dust collection box for a cleaning robot and the cleaning robot itself. Background Technology

[0002] Smart home devices are playing an increasingly important role in people's lives, leading to their proliferation. Among these, cleaning robots are a common type. During cleaning, the robot's rotating brushes lift dust and other debris from the floor, sending it to the suction port where it is drawn into the robot's dustbin.

[0003] After using the cleaning robot for a period of time, users need to remove the dustbin and empty the collected trash. In related technologies, after the dustbin lid is opened, the trash inside is emptied into the trash can through the dumping spout. During the emptying process, the lid swings freely, causing the spilled trash to be blown up, easily falling outside the trash can or scattering into the air, ultimately leading to re-polluting the indoor environment. Summary of the Invention

[0004] The purpose of this application is to disclose a dust collection box for a cleaning robot and a cleaning robot, which can solve the problem described in the background art where the dust collection box lid swings freely during the emptying process, causing the dumped garbage to be fanned up and ultimately leading to indoor re-contamination.

[0005] To solve the above-mentioned technical problems, this application is implemented as follows:

[0006] In a first aspect, embodiments of this application disclose a dust collection box for a cleaning robot. The disclosed dust collection box for the cleaning robot includes a box body and a box lid. The box body has a waste dumping port, the box lid has a first connecting structure, and the box body has a second connecting structure. The box lid is rotatably connected to the box body to switch between an open state and a closed state. The box body has an elastic positioning protrusion, and the elastic positioning protrusion and the box body form an elastic positioning space, wherein:

[0007] When the lid is in the open state, the waste dumping port is exposed, and the first connecting structure is separated from the second connecting structure. The lid and the elastic positioning space are positioned and engaged in the rotation direction of the lid.

[0008] When the lid is in the closed state, the lid seals the waste dumping opening, and the first connecting structure and the second connecting structure are detachably connected, while the lid is disengaged from the elastic positioning space.

[0009] Secondly, this application discloses a cleaning robot, which includes a dust collection box and a base as described above. The base has an installation space, and the dust collection box is detachably installed in the installation space.

[0010] The technical solution adopted in this application can achieve the following beneficial effects:

[0011] The dust collection box disclosed in this application improves upon the structure of dust collection boxes in related technologies by providing elastic positioning protrusions on the box body, creating an elastic positioning space between the protrusions and the box body. When the lid is open, the first connecting structure and the second connecting structure separate, exposing the garbage disposal opening that was previously sealed by the lid, thus facilitating the user to empty the garbage from the box into the garbage bin through the disposal opening. Because the lid is rotatably connected to the box body, it can rotate relative to the box body. During this rotation, the user applies a significant rotational force to the lid, causing it to pass over an elastic positioning protrusion. This protrusion deforms to avoid the lid's rotation, allowing the lid to rotate to a position that aligns with the elastic positioning space. Ultimately, the lid and the elastic positioning space are positioned in the direction of the lid's rotation, thus maintaining a fixed relative position between the lid and the box body. This effectively prevents the lid from swinging and scattering trash when the user emptys the box, causing trash to fall outside the trash can or become airborne. Attached Figure Description

[0026] 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, 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.

[0027] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and are not used to describe a specific order or sequence. It should be understood that such data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and are not limited in number; for example, a first object can be one or more.

[0028] The dust collection box of the cleaning robot provided in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0029] like Figures 1 to 5As shown in the figure, this application discloses a dust collection box for a cleaning robot. The disclosed dust collection box for the cleaning robot includes a box body 100 and a box cover 200. The box body 100 is the main functional structure of the dust collection box, that is, the box body 100 is the main component for the cleaning robot to collect garbage. The box cover 200 is used in conjunction with the box body 100 to realize the collection and disposal of garbage by the cleaning robot.

[0030] The container body 100 is provided with a waste dumping port 110, which connects the internal space of the container body 100 with the external environment, allowing users to conveniently dispose of the waste collected in the container body 100. The lid 200 is provided with a first connecting structure 210, and the container body 100 is provided with a second connecting structure 120. The lid 200 and the container body 100 are rotatably connected, allowing the lid 200 to switch between an open and closed state. The container body 100 is provided with an elastic positioning protrusion 130, which forms an elastic positioning space 140 with the container body 100. The elastic positioning space 140 is used to achieve a limiting fit between the lid 200 and the container body 100.

[0031] Specifically, with the lid 200 in the open position, the waste disposal opening 110 is exposed, allowing the user to empty the waste from the container 100 through the opening. During the exposure of the waste disposal opening 110, the lid 200 is opened, separating the first connecting structure 210 from the second connecting structure 120. Because the container 100 and lid 200 are rotatably connected, the lid 200 swings freely when open, causing it to fan out the waste inside the container 100, resulting in the waste falling outside the trash can or scattering into the air during the emptying process.

[0032] To prevent the above-mentioned phenomenon, the dust collection box disclosed in this application embodiment is provided with an elastic positioning protrusion 130, and an elastic positioning space 140 is formed between the elastic positioning protrusion 130 and the box body 100. When the box lid 200 is in the open state, the box lid 200 and the elastic positioning space 140 are positioned and engaged in the rotation direction of the box lid 200. That is, the elastic positioning space 140 can position the box lid 200, which rotates relative to the box body 100. This ensures that when the user pours out the garbage in the box body 100, the position between the box lid 200 and the box body 100 is relatively fixed, so that the box lid 200 cannot sweep the garbage in the box body 100 and the poured garbage. This solves the problem in the prior art where the box lid 200 swings freely when it is opened, causing the poured garbage in the box body 100 to fall outside the garbage can or float in the air.

[0033] When the lid 200 is closed, it can seal the garbage dumping opening 110, forming a closed dust collection chamber between the lid 200 and the box body 100. The dust collection chamber is used to temporarily store the garbage collected by the cleaning robot after cleaning, so that the garbage in the box body 100 cannot fall out of the garbage dumping opening 110. At this time, the first connecting structure 210 and the second connecting structure 120 are detachably connected to realize the function of the lid 200 sealing the garbage dumping opening 110. The lid 200 is disengaged from the elastic positioning space 140, that is, the lid 200 and the elastic positioning space 140 only need to be positioned when the lid 200 is open.

[0034] The dust collection box disclosed in this application improves upon the structure of dust collection boxes in related technologies by providing an elastic positioning protrusion 130 on the box body 100, forming an elastic positioning space 140 between the elastic positioning protrusion 130 and the box body 100. When the lid 200 is open, the first connecting structure 210 and the second connecting structure 120 separate, exposing the garbage dumping port 110 covered by the lid 200, thus facilitating the user to empty the garbage inside the box body 100 into the garbage bin through the garbage dumping port 110. Because the lid 200 is rotatably connected to the box body 100, the lid 200 can rotate relative to the box body 100. During the rotation of the lid 200, the user applies a large rotational driving force to the lid 200, causing the lid 200 to pass through the elastic positioning protrusion 130. The elastic positioning protrusion 130 deforms to avoid the rotation of the lid 200, thus causing the lid 200 to rotate to a position that matches the elastic positioning space 140. Finally, the lid 200 and the elastic positioning space 140 are positioned and matched in the rotation direction of the lid 200, so that the lid 200 and the box body 100 have a fixed relative position. This solves the problem that the lid 200 swings and blows up the garbage when the user pours out the garbage from the box body 100, which may cause the garbage to fall out of the garbage can or be scattered into the air.

[0035] In the dust collection box disclosed in this application embodiment, the box cover 200 may include a cover body 220, a connecting arm 230 and a connecting shaft 240. The connecting shaft 240 is fixedly connected to the cover body 220 through the connecting arm 230. The connecting shaft 240 intersects with the connecting arm 230. The box body 100 may also have a connecting hole 161. The connecting shaft 240 is rotatably engaged with the connecting hole 161. When the box cover 200 is in the open state, the connecting arm 230 is positioned and engaged with the elastic positioning space 140 in the rotation direction.

[0036] In the above case, the lid 200 and the box body 100 are rotated together through the connecting arm 230, the connecting shaft 240 and the connecting hole 161, and the lid 220 is positioned together with the elastic positioning space 140 through the connecting arm 230. Since the connecting shaft 240 is fixedly connected to the cover 220 through the connecting arm 230, and the connecting arm 230 and the elastic positioning space 140 are positioned and engaged in the rotation direction, the engagement between the connecting shaft 240, the connecting arm 230 and the elastic positioning space 140 conforms to the lever principle. That is, the setting of the connecting arm 230 makes the positioning engagement position between the connecting arm 230 and the elastic positioning space 140 far away from the connecting shaft 240. In other words, the engagement between the elastic positioning protrusion 130 and the connecting arm 230 is equivalent to using a force-saving lever. Thus, under the same torque, the positioning engagement of the connecting arm 230 and the elastic positioning space 140 in the rotation direction can reduce the magnitude of the force on the elastic positioning protrusion 130, thereby preventing the elastic positioning protrusion 130 from being crushed and deformed due to excessive squeezing force. This helps to ensure the functionality of the elastic positioning protrusion 130 and extend its service life.

[0037] In a further technical solution, the box body 100 may also include a connecting stiffener 160, the connecting stiffener 160 may have a connecting hole 161, the surface of the connecting stiffener 160 may also have an elastic positioning protrusion 130, and the box body 100 may include a protruding ridge 170 protruding from the surface of the connecting stiffener 160, and an elastic positioning space 140 is formed between the protruding ridge 170 and the elastic positioning protrusion 130.

[0038] In the above configuration, the sidewall of the box body with the protruding ridge 170 forms the main structure of the box body 100. The connecting rib 160 has a connecting hole 161, and the protruding ridge 170 protrudes from the surface of the connecting rib 160, allowing the connecting rib 160 to function specifically as a connector even though it is thinner than the other sidewalls of the box body 100. Furthermore, since the protruding ridge 170 protrudes from the surface of the connecting rib 160, a stepped structure is formed between the connecting rib 160 and the protruding ridge 170, allowing an elastic positioning space 140 to be formed on the lower stepped surface, thus enhancing the overall design ingenuity of the box body 100. The connecting rib 160 can be made of high-strength sheet metal material. Of course, the connecting rib 160 can also be made of other high-strength materials. This embodiment does not impose specific limitations on the materials used for the connecting rib 160.

[0039] In a more specific technical solution, in order to improve the stability of the rotational connection between the box body 100 and the box cover 200, there can be two connecting ribs 160, two connecting arms 230 and two connecting shafts 240, and the two connecting arms 230 and the two connecting shafts 240 are connected in a one-to-one correspondence. The connecting shafts 240 are rotatably engaged with the connecting holes 161 of the corresponding connecting ribs 160, and the two connecting ribs 160 are spaced apart.

[0040] In the above scenario, the corresponding engagement between the two connecting arms 230 and the connecting shaft 240 can distribute the connection weight of the lid 200, so that one connecting arm 230 and its corresponding connecting shaft 240 do not need to bear the entire connection weight of the lid 200. Furthermore, both connecting ribs 160 can be provided with elastic positioning protrusions 130, thereby forming elastic positioning spaces 140 on both connecting ribs 160. This allows the two elastic positioning spaces 140 to respectively engage with the corresponding connecting arm 230 in the rotation direction of the lid 200, undoubtedly improving the stability of the positioning engagement between the box body 100 and the lid 200. After the user emptys the waste from the box body 100, the user can manually push the lid 220 to rotate, thereby releasing the restriction between the connecting arm 230 and the elastic positioning space 140. This facilitates the subsequent sealing of the box body 100 by the lid 220, allowing the dust collection box to be reinstalled on the cleaning robot for use.

[0041] In the dust collection box disclosed in this application embodiment, the box body 100 may also have an elastic notch 180. The elastic notch 180 communicates with the connecting hole 161 and is used for the connecting shaft 240 to enter and exit the connecting hole 161. The opening width of the elastic notch 180 is smaller than the diameter of the connecting shaft 240. In this case, the connecting shaft 240 can be directly installed and removed from the connecting hole 161 through the elastic notch 180, which is beneficial to improving the convenience of assembly between the connecting shaft 240 and the connecting hole 161. At the same time, since the elastic notch 180 is elastic and its opening width is smaller than the diameter of the connecting shaft 240, the elastic notch 180 can ensure the stability of the connecting shaft 240 installed in the connecting hole 161, that is, it can prevent the connecting shaft 240 from falling off the connecting hole 161 by itself through the elastic notch 180.

[0042] In the dust collection box disclosed in this application embodiment, the elastic positioning protrusion 130 can be an arc-shaped protrusion with the rotation axis of the box cover 200 as the center. In this case, the elastic positioning protrusion 130 has a certain length, so that the connecting arm 230 can achieve positioning engagement with the elastic positioning protrusion 130 within a certain rotation angle range. This helps to avoid the point-like elastic positioning protrusion 130 being crushed and deformed, which would cause the box cover 200 and the elastic positioning space 140 to fail to position.

[0043] In the dust collection box disclosed in this application embodiment, the waste dumping port 110 can be opened on the side wall of the box body 100. The bottom end of the box cover 200 is rotatably connected to the bottom end of the box body 100. The top end of the box cover 200 is provided with a first connecting structure 210, and the top end of the box body 100 is provided with a second connecting structure 120. The top of the box body 100 is provided with a receiving cavity 190, which has an opening. The dust collection box may also include a button 300 rotatably disposed at the opening of the receiving cavity 190. The rotation center of the button 300 is located between the first end and the second end of the button 300. The second connecting structure 120 is a snap-fit ​​protrusion, and the first connecting structure 210 is a snap-fit ​​groove. An elastic reset member 600 is provided between the bottom wall of the receiving cavity 190 and the first end of the button 300. The snap-fit ​​protrusion is connected to the second end of the button 300. When the box cover 200 is in the closed state, the snap-fit ​​protrusion passes through the bottom wall of the receiving cavity 190 and extends into the snap-fit ​​groove.

[0044] In the above configuration, the box body 100 and the lid 200 are connected by a snap-fit ​​protrusion and a snap-fit ​​groove. A resilient reset member 600 is positioned between the bottom wall of the receiving cavity 190 and the first end of the button 300. This prevents the resilient reset member 600 from being exposed outside the button 300, thus avoiding user misoperation. Simultaneously, due to its elasticity, the resilient reset member 600's elastic force drives the button 300, causing the snap-fit ​​protrusion at the second end of the button 300 to engage with the snap-fit ​​groove. This ensures stable connection between the snap-fit ​​protrusion and the snap-fit ​​groove when the lid 200 is closed. Furthermore, pressing the button 300 overcomes the elastic force of the resilient reset member 600, causing the button 300 to rotate and disengage from the snap-fit ​​protrusion and the snap-fit ​​groove, making it easier for the user to open the lid 200.

[0045] In one specific embodiment, the elastic reset member 600 can be a spring. A positioning protrusion can be provided on the inner surface of the first end of the button 300, and one end of the spring is inserted into the positioning protrusion to maintain the spring's extension and contraction stability and installation stability, thus preventing the spring from tipping over. The outer surface of the second end of the button 300, used for user pressing, can be provided with anti-slip textures. These textures serve as markings and also prevent slippage, thereby improving the user's pressing experience. The inner surface of the button 300 faces the dust collection chamber, while the outer surface faces away from the dust collection chamber; the outer surface of the button 300 is also the surface visible to the user. The elastic reset member 600 can also be other elastic structures; this application embodiment does not specifically limit the structure of the elastic reset member 600.

[0046] Of course, the first connecting structure 210 and the second connecting structure 120 can also be other structures that can achieve detachable connection. For example, one of the first connecting structure 210 and the second connecting structure 120 can be a first magnetic component, and the other can be a second magnetic component, which can be magnetically connected. During the process of opening the lid 200, the user can simply manually pry open the lid 200 to overcome the magnetic force.

[0047] In a further technical solution, the dust collection box may also include a handle 400, which is rotatably mounted on the box body 100 to switch between an unfolded state and a folded state, thereby facilitating user operation. Specifically, when the handle 400 is in the unfolded state, the hand grip portion 410 of the handle 400 is positioned opposite the first end of the button 300, resulting in a short distance between the hand grip portion 410 and the button 300. This allows the user to press the button 300 with the same hand while gripping the handle 400. To further facilitate pressing the button 300, the user can grip the hand grip portion 410, which is positioned opposite the button 300 in the unfolded state.

[0048] When the handle 400 is in the folded state, it is located in the handle receiving groove 150 of the box body 100. In this case, the handle receiving groove 150 can store the folded handle 400, thereby helping to reduce the overall size of the dust collection box when the handle 400 is folded.

[0049] In a more specific technical solution, the cleaning robot may include a base 500, which may have an installation space. The two opposite sidewalls of the installation space may each have a groove. The surface of the base 500 has a disengagement opening 510, which communicates with the groove. The handle 400 includes a handle body 420 and hook-on protrusions 430 at both ends of the handle body 420. The handle body 420 is rotatably connected to the box 100. The hook-on protrusions 430 rotate with the handle body 420 to switch between an engaged state and a disengaged state. In the engaged state, the hook-on protrusions 430 rotate into the groove and face the sidewall of the adjacent surface of the base 500. In the opening direction of the installation space, the hook-on protrusions 430 engage with the sidewall of the groove. In the disengaged state, the hook-on protrusions 430 rotate to the disengagement opening 510, and the hook-on protrusions 430 are misaligned with the sidewall of the groove.

[0050] In the above scenario, because the hook-on protrusion 430 can rotate with the handle body 420, the handle body 420 can drive the hook-on protrusion 430 to different states depending on the state of the handle 400 (i.e., the state of the handle body 420). This means the hook-on protrusion 430 can be in an engaged or disengaged state, and the unfolded state of the handle body 420 corresponds to the disengaged state of the hook-on protrusion 430, while the folded state of the handle body 420 corresponds to the engaged state of the hook-on protrusion 430. In other words, the hook-on protrusion 430 fully utilizes the foldable performance of the handle body 420. During the disassembly and installation of the dust collection box, the hook-on protrusion 430 automatically disengages when the user pulls the handle body 420, and automatically engages when the user installs the dust collection box and releases the handle body 420, thus facilitating the user's overall disassembly and installation of the dust collection box.

[0051] In the dust collection box disclosed in the embodiments of this application, the dust collection box may further include a high-efficiency particulate air filter (HEPA) component 700. The HEPA component 700 only allows air to pass through, but does not allow fine particles to pass through, so that fine dust or smoke particles in the dust collection box cannot pass through the HEPA component 700 and fall from the box body 100 into the outside air, thereby improving the cleaning performance of the dust collection box. To prevent the garbage already collected in the container 100 from accidentally falling back out of the container 100 through the garbage collection opening, thus causing the garbage in the container 100 to come into contact with the external environment and resulting in re-contamination or incomplete cleaning, a check valve 800 can be installed at the garbage collection opening on the container 100. The check valve 800 is a one-way valve and can be used in conjunction with a fan. The fan can create a negative pressure environment in the garbage collection space of the container 100, so that the check valve 800 can open towards the space inside the container 100, thus ensuring that the garbage can only be drawn into the container 100 from the external environment.

[0052] This application also discloses a cleaning robot, which includes a base 500 and a dust collection box as described above. The base 500 is provided with an installation space, and the dust collection box is detachably installed in the installation space, so that the user can easily remove the dust collection box from the installation space to empty the garbage in the dust collection box, which is conducive to the subsequent recycling of the dust collection box.
