Description

Technical Field

[0001] The present application belongs to the technical field of cleaning appliances, and in particular relates to a dust collecting device and a dust collecting pile. Background Art

[0002] Many cleaning devices (for example, cleaning robots or base stations) usually use fans to drive airflow to generate suction to suck in and collect garbage. Existing cleaning devices are equipped with a detachable dust bucket, which includes a barrel and a cyclone cone. When dumping garbage, users need to take out the cyclone cone first, and then pour out the garbage from the top of the barrel. In this way, when taking out the cyclone cone, due to too much garbage in the barrel, the garbage is easy to fall from the air flow channel connecting the barrel and the base station / host, causing the garbage to fall on the user or the ground, affecting the user's experience; in addition, the existing dust bucket is provided with a accommodating cavity, and an air inlet and an air outlet connected to the accommodating cavity are opened. When the cyclone cone is separated from the dust bucket, the installation area of ​​the dust bucket for installing the cyclone cone forms a dumping port for dumping garbage. Since the air outlet is also connected to the accommodating cavity, the user may think that the air outlet is the dumping port for dumping garbage, causing the user to misjudge. Utility Model Content

[0003] The present application provides a dust collecting device and a dust collecting pile to solve the technical problem that when taking out the existing cyclone cone, garbage easily falls from the air flow channel connecting the barrel body and the base station / host.

[0004] The technical solution adopted in this application is:

[0005] A dust collecting device comprises a dust bucket and a cyclone separator, the dust bucket is provided with a top opening, a dust inlet and a docking channel, the cyclone separator is installed in the dust bucket through the top opening of the dust bucket, the cyclone separator is provided with an exhaust channel, one end of the docking channel is docked with the exhaust channel, and the other end is docked with an external negative pressure source, the cyclone separator has a disassembled state separated from the dust bucket and an installed state matched with the dust bucket, an opening and closing assembly is provided in the docking channel, and when the cyclone separator is in the disassembled state, the opening and closing assembly is biased in a closed state to close the docking channel.

[0006] The dust collecting device in the present application also includes the following additional technical features:

[0007] When the cyclone separator is in an installed state, in response to the negative pressure force applied by the negative pressure source on the opening and closing component being greater than a threshold value, the opening and closing component switches from the closed state to the open state where the docking channel is opened.

[0008] The end of the exhaust channel is provided with a resistance piece which interferes with the closing direction of the opening and closing component. When the cyclone separator is in the installed state, in response to the resistance of the resistance piece, the opening and closing component switches from the closed state to the open state of opening the docking channel.

[0009] The opening and closing assembly includes a plate component and an elastic component connected to the plate component, wherein the elastic component is configured to bias the plate component to a position closing the docking channel.

[0010] The elastic component is a torsion spring structure, a hinge portion is provided on one side of the inner wall of the docking channel, any side edge of the plate component is hinged to the hinge portion, the torsion spring structure is provided on one side of the plate component close to the hinge portion, and both ends of the torsion spring structure are fixedly connected to the plate component and the inner wall of the docking channel respectively.

[0011] A stop portion is provided on the inner wall of the docking channel, and the stop portion is arranged opposite to the hinge portion. The opening and closing assembly rotates along a first direction away from the stop portion to open the docking channel, and the elastic component drives the opening and closing assembly to rotate along a second direction opposite to the first direction to a position against the stop portion to close the docking channel.

[0012] The opening and closing assembly includes a plate component, the shape of which matches the inner cross-section of the docking channel. The plate component is an elastic sheet. A fixing portion perpendicular to the plate component is fixedly connected to any side edge of the plate component, and the fixing portion is fixedly connected to the inner wall of the docking channel.

[0013] A handle is provided above the cyclone separator.

[0014] It also includes a mounting base and an anti-foolproofing member for mounting the dust bucket, wherein the anti-foolproofing member includes an anti-foolproofing protrusion arranged on either the mounting base or the bottom of the dust bucket, and an anti-foolproofing groove arranged on the other, wherein the anti-foolproofing protrusion cooperates with the anti-foolproofing groove.

[0015] A dust collecting pile comprises a pile body and a negative pressure source, wherein the negative pressure source is connected to an exhaust channel, the negative pressure source and the exhaust channel are arranged below a docking channel, and a sealing member is fixed to the docking portion of the exhaust channel.

[0016] Due to the adoption of the above technical solution, the beneficial effects achieved by this application are as follows:

[0017] 1. In the present application, when the negative pressure source is in a closed state or when the cyclone separator is in a disassembled state separated from the dust bin, the opening and closing assembly is biased in a closed state to close the docking channel. When the user dumps the garbage in the dust bin, the garbage scattered from the inner cavity of the dust bin into the docking channel will be blocked in the docking channel by the opening and closing assembly, preventing the garbage from falling from the docking channel when the user is cleaning the garbage in the dust bin, causing pollution to the user's clothes or the ground, thereby affecting the user's experience.

[0018] On the other hand, closing the docking channel by the opening and closing component can serve to remind the user that the docking channel cannot be used as a garbage dumping channel, eliminating the user's doubts about whether the garbage should be poured out from the docking channel or the top opening of the dust bin, and preventing the user from making misjudgments when dumping garbage in the dust bin.

[0019] 2. The gas flow can form a downward negative pressure force acting on the opening and closing component. When the downward negative pressure force is greater than the flipping resistance of the opening and closing component, the opening and closing component can be driven to flip downward, so that the opening and closing component is switched from a closed state to an open state; when the gas flow stops, the negative pressure force acting on the opening and closing component disappears, and the opening and closing component is reset from the open state to the closed state of closing the docking channel, thereby preventing garbage from falling from the docking channel.

[0020] 3. The resistance piece moves toward the docking channel along with the exhaust channel and abuts against the edge area of ​​the opening and closing assembly and pushes the opening and closing assembly to rotate. Under the resistance of the resistance piece, the opening and closing assembly is transformed from a closed state to an open state in which the docking channel is opened. When the cyclone separator is separated from the dust bin, the resistance piece is separated from the opening and closing assembly so that the pressure acting on the opening and closing assembly disappears, and the opening and closing assembly is transformed from an open state to a closed state in which the docking channel is closed, thereby ensuring that the docking channel is in a closed state when the cyclone separator is separated from the dust bin, thereby preventing garbage from falling from the docking channel.

[0021] 4. When the negative pressure source drives the gas in the docking channel to flow from top to bottom, the side of the plate component away from the fixed part flips downward around the fixed part under the action of the negative pressure force to open the docking channel and store elastic potential energy. When the negative pressure source stops working, the elastic potential energy of the plate component is released to cause the side of the plate component away from the fixed part to flip upward and reset, thereby realizing timely closing of the docking channel and preventing garbage from falling into the docking channel.

[0022] 5. In the process of the plate component being converted from the closed state of closing the docking channel to the open state of opening the docking channel, the elastic component is in a compressed state due to the flipping of the plate component, so that the elastic component stores elastic potential energy. When the force driving the plate component to be converted from the closed state to the open state is cancelled, the elastic potential energy stored in the elastic component is released, and then the driving plate component is automatically reset from the open state to the closed state of closing the docking channel, thereby realizing the timely closure of the docking channel after the force is cancelled, preventing garbage from falling from the docking channel.

[0023] 6. The stopper can be used to limit and position the opening and closing assembly to prevent the opening and closing assembly from rotating too much in the second direction, causing a gap between the opening and closing assembly and the inner wall of the docking channel, resulting in a small amount of garbage passing through the gap.

[0024] On the other hand, the stopper can seal the connection seam between the opening and closing component and the inner wall of the docking channel, thereby ensuring the sealing of the edge of the opening and closing component when the opening and closing component abuts against the stopper, further preventing garbage from entering the docking channel from flowing out, and improving the user experience.

[0025] 7. The opening and closing component is located at the end of the docking channel away from the bottom of the dust bin. The closer the opening and closing component is to the upper end of the docking channel, the smaller the volume of the storage slot is, the less garbage can be accommodated, the smaller the maximum load-bearing capacity of the opening and closing component is, and the smaller the force required to drive the opening and closing component to reset is. When the negative pressure source is working, the larger the opening angle of the opening and closing component under the same negative pressure force, the larger the wind flow area at the opening and closing component position will be, thereby forming a smaller wind resistance and effectively reducing suction loss.

[0026] The closer the rotation angle of the opening and closing component is to 90°, the smaller the resistance of the opening and closing component to the airflow passing through the docking channel, so that the suction loss is smaller, thereby ensuring the dust collection effect and efficiency. In order to ensure that the maximum rotation angle of the opening and closing component is 90°, the plate component can be set as a flexible plate component. After the plate component is flipped to interfere with the inner wall of the docking channel, the area where the flexible plate component and the docking channel are in contact can produce deformation that adapts to the inner wall of the docking channel to ensure the rotation angle of the plate component.

[0027] 8. When installing the dust bin, the user should first confirm that the anti-foolproof protrusion and the anti-foolproof groove are on the same side. The setting of the anti-foolproof protrusion and the anti-foolproof groove can facilitate the user to install the dust bin quickly and accurately, thereby improving the user experience.

[0028] 9. The joint part of the exhaust channel is fixed with a seal, which can seal the joint part to prevent airflow leakage from the joint part and cause suction loss. Moreover, the seal is arranged on the exhaust channel, and there is no risk of the seal being detached due to cleaning the dust bin. BRIEF DESCRIPTION OF THE DRAWINGS

[0055] like Figure 1As shown, a dust collecting device includes a dust bucket 10 and a cyclone separator 20. The dust bucket 10 is provided with a top opening, a dust inlet 11 and a docking channel 12. The cyclone separator 20 is installed in the dust bucket 10 through the top opening of the dust bucket 10. The cyclone separator 20 is provided with an exhaust channel 21. One end of the docking channel 12 is docked with the exhaust channel 21, and the other end is docked with an external negative pressure source 30. The cyclone separator 20 has a disassembled state separated from the dust bucket 10 and an installed state matched with the dust bucket 10. An opening and closing assembly is provided in the docking channel 12. When the cyclone separator 20 is in the disassembled state, the opening and closing assembly is biased in a closed state to close the docking channel 12.

[0056] When the present application is in working state, the external negative pressure source 30 is started to suck the external air of the dust bucket 10 into the dust bucket 10 along the dust inlet 11, and then enter the docking channel 12 after passing through the cyclone separator 20 and the exhaust channel 21 in sequence. The airflow passes through the docking channel 12 from top to bottom, enters the negative pressure source 30 along the suction end of the negative pressure source 30, and is discharged along the exhaust end of the negative pressure source 30. In the process, dust particles enter the inner cavity of the dust bucket 10 with the airflow, and under the filtering action of the cyclone separator 20, dust particles, garbage and other materials are stagnant in the dust bucket 10.

[0057] When a certain amount of garbage is collected in the inner cavity of the dust bin 10, the upper port of the inner cavity of the dust bin 10 is opened by removing the cyclone separator 20, and then the garbage is poured out along the upper port of the dust bin 10 to clean the garbage collected inside the dust bin 10.

[0058] When the negative pressure source 30 is in working state or when the cyclone separator 20 and the dust bucket 10 are in a mutually coordinated installation state, the opening and closing assembly is in an open state of opening the docking channel 12 to ensure that the airflow channel from the dust inlet 11 to the exhaust end of the negative pressure source 30 is in a smooth state, thereby ensuring the dust collection effect. When the negative pressure source 30 is in a closed state or when the cyclone separator 20 is in a disassembled state separated from the dust bucket 10, the opening and closing assembly is biased in a closed state of closing the docking channel 12. When the user dumps the garbage in the dust bucket 10, the garbage scattered from the inner cavity of the dust bucket 10 into the docking channel 12 will be blocked by the opening and closing assembly in the docking channel 12, preventing the garbage from spilling out of the docking channel 12 when the user is cleaning the garbage in the dust bucket 10, causing pollution to the user's clothes or the ground, and affecting the user's experience.

[0059] On the other hand, when the cyclone separator 20 is in a disassembled state, the top opening of the dust bin 10 is opened to form a dumping port for dumping garbage. At the same time, the opening and closing assembly is biased in a closed state to close the docking channel 12. The opening and closing assembly closing the docking channel 12 can serve to remind the user that the docking channel 12 cannot be used as a garbage dumping channel, eliminating the user's doubts about whether the garbage should be poured out from the docking channel 12 or the top opening of the dust bin 10, preventing the user from making misjudgments when dumping the garbage in the dust bin 10, thereby improving the user's experience.

[0060] The present application does not specifically limit the driving method of the opening and closing component state, and any one of the following embodiments may be adopted:

[0061] Embodiment 1: Figure 1 , Figure 2 as well as Figure 4 As shown, the cyclone separator 20 is in the installed state. In response to the negative pressure force applied by the negative pressure source 30 on the opening and closing component being greater than a threshold value, the opening and closing component is switched from the closed state to the open state of opening the docking channel 12.

[0062] When the negative pressure source 30 is in the on state, the negative pressure source 30 inhales the air on one side of the suction end and discharges it along the exhaust end, so that the air pressure above the opening and closing component is greater than the air pressure below the opening and closing component, forming a negative pressure force acting downward on the opening and closing component. When the downward negative pressure force is greater than the flipping resistance of the opening and closing component, the opening and closing component can be driven to flip downward, so that the opening and closing component is converted from the closed state to the open state; when the negative pressure source 30 is in the off state, the negative pressure force acting on the opening and closing component disappears, and the opening and closing component is reset from the open state to the closed state of closing the docking channel 12.

[0063] Embodiment 2: Figure 3 , Figure 5 as well as Figure 6 As shown, the end of the exhaust channel 21 is provided with a resistance member 22 which interferes with the closing direction of the opening and closing component. When the cyclone separator 20 is in the installed state, in response to the resistance action of the resistance member 22, the opening and closing component is switched from the closed state to the open state of opening the docking channel 12.

[0064] During the installation process of the cyclone separator 20 and the dust bin 10, the resistance member 22 moves along with the exhaust channel 21 toward the docking channel 12 and abuts against the edge area of ​​the opening and closing assembly to push the opening and closing assembly to rotate. Under the resistance of the resistance member 22, the opening and closing assembly is transformed from a closed state to an open state in which the docking channel 12 is opened; when the cyclone separator 20 is separated from the dust bin 10, the resistance member 22 moves along with the exhaust channel 21 in a direction away from the closing assembly. The separation of the resistance member 22 from the opening and closing assembly causes the pressure acting on the opening and closing assembly to disappear, and the opening and closing assembly is transformed from an open state to a closed state in which the docking channel 12 is closed.

[0065] Embodiment 3: The opening and closing assembly includes a plate component 40, the shape of which matches the inner cross section of the docking channel 12, and the plate component 40 is an elastic sheet. A fixing portion perpendicular to the plate component 40 is fixedly connected to any side edge of the plate component 40, and the fixing portion is fixedly connected to the inner wall of the docking channel 12. When the negative pressure source 30 is working, the side of the plate component 40 away from the fixing portion flips downward around the fixing portion under the action of the negative pressure force to open the docking channel 12 and store elastic potential energy. When the negative pressure source 30 stops working, the elastic potential energy of the plate component 40 is released to cause the side of the plate component 40 away from the fixing portion to flip upward and reset, closing the docking channel 12.

[0066] Embodiment 4: The opening and closing assembly switches between the open state and the closed state by electric control, and the user can flexibly switch the position state of the opening and closing assembly according to the actual usage scenario. For example, a small servo motor is installed in the docking channel 12, and the output end of the servo motor is coaxially arranged with the opening and closing assembly to drive the opening and closing assembly to rotate. When it is necessary to clean the garbage in the dust bin 10, the servo motor is controlled to drive the opening and closing assembly to switch from the open state to the closed state. Before the negative pressure source 30 is started, the servo motor is controlled to drive the opening and closing assembly to switch from the closed state to the open state.

[0067] As a specific embodiment of the opening and closing assembly in the present application, the opening and closing assembly includes a plate component 40 and an elastic component connected to the plate component 40 , and the elastic component is configured to bias the plate component 40 to a position to close the docking channel 12 .

[0068] When the plate component 40 is in the closed state of closing the docking channel 12, the elastic component is in the initial state. During the process of the plate component 40 being converted from the closed state of closing the docking channel 12 to the open state of opening the docking channel 12, the elastic component is in a compressed state due to the flipping of the plate component 40, so that the elastic component stores elastic potential energy. When the force driving the plate component 40 to be converted from the closed state to the open state is cancelled, the elastic potential energy stored in the elastic component is released, thereby driving the plate component 40 to automatically reset from the open state to the closed state of closing the docking channel 12.

[0069] The present application does not specifically limit the structure of the elastic component in the above embodiment, and it can adopt any one of the following embodiments:

[0070] Embodiment 5: Fig.12 As shown, the elastic component is a torsion spring 41, and a hinge portion is provided on one side of the inner wall of the docking channel 12. Any side edge of the plate component 40 is hinged to the hinge portion. The torsion spring 41 structure is provided on one side of the plate component 40 close to the hinge portion, and both ends of the torsion spring 41 structure are respectively fixedly connected to the plate component 40 and the inner wall of the docking channel 12. The plate component 40 flips downward around the hinge portion to open the docking channel 12 while squeezing the torsion spring 41, so that the torsion spring 41 stores elastic potential energy. The elastic potential energy stored in the torsion spring 41 is used to reset the plate component 40 to the closed state of closing the docking channel 12 after the driving force applied to the plate component 40 disappears.

[0071] Embodiment 6: The elastic component is a compression spring, and both ends of the compression spring are fixedly connected to the bottom wall of the plate component 40 and the inner wall of the docking channel 12 respectively. The plate component 40 flips downward to open the docking channel 12 and squeezes the compression spring at the same time, so that the compression spring stores elastic potential energy. The elastic potential energy stored in the compression spring is used to restore the plate component 40 to the closed state of closing the docking channel 12 when the driving force applied to the plate component 40 disappears.

[0072] As a preferred implementation of the present application, Figure 2 , Figure 3 , Figure 6 as well as Fig. 9 As shown, the inner wall of the docking channel 12 is provided with a stopper 13, and the stopper 13 is arranged opposite to the hinge part. The opening and closing assembly rotates away from the stopper 13 in a first direction to open the docking channel 12, and the elastic component drives the opening and closing assembly to rotate in a second direction opposite to the first direction to a position that abuts against the stopper 13 to close the docking channel 12. The setting of the stopper 13 can limit and position the opening and closing assembly, and prevent the opening and closing assembly from rotating too much in the second direction, so that a gap appears between the opening and closing assembly and the inner wall of the docking channel 12, resulting in a small amount of garbage passing through the gap. On the other hand, the stopper 13 can seal the connection seam between the opening and closing assembly and the inner wall of the docking channel 12, thereby ensuring the sealing of the edge of the opening and closing assembly when the opening and closing assembly abuts against the stopper 13, and further preventing the garbage entering the docking channel 12 from flowing out.

[0073] As a preferred example of this application, Figure 1-Figure 6 as well as Fig. 9As shown, the opening and closing component is located at one end of the docking channel 12 away from the bottom of the dust bin 10. When the opening and closing component is in a closed state of closing the docking channel 12, the opening and closing component and the docking channel 12 above it form a storage groove for storing scattered garbage. The closer the position of the opening and closing component is to the upper end of the docking channel 12, the smaller the volume of the storage groove is, and the less garbage can be accommodated. When the storage groove is full of garbage, the smaller the load weight applied to the opening and closing component is, the smaller the maximum bearing capacity of the opening and closing component is, and the smaller the force required to drive the opening and closing component to reset is. When the negative pressure source 30 is working, the larger the opening angle of the opening and closing component under the same negative pressure force, the larger the wind flow area at the position of the opening and closing component will be, thereby forming a smaller wind resistance, effectively reducing the suction loss.

[0074] The closer the rotation angle of the opening and closing component is to 90°, the smaller the resistance of the opening and closing component to the airflow passing through the docking channel 12, so that the suction loss is smaller, thereby ensuring the dust collection effect and efficiency. In order to ensure that the maximum rotation angle of the opening and closing component is 90°, the plate component 40 can be set as a flexible plate component 43. After the plate component 40 is turned over to interfere with the inner wall of the docking channel 12, the area where the flexible plate component 43 and the docking channel 12 are in contact can produce deformation that adapts to the inner wall of the docking channel 12 to ensure the rotation angle of the plate component 40.

[0075] Preferably, if Fig.10 As shown, the plate component 40 includes a rigid plate component 42 and a flexible plate component 43 which is arranged on the edge of the rigid component and extends outward. The rigid plate component 42 and the flexible plate component 43 are spliced ​​so that their combined overall shape is the same as the inner cross-section of the docking channel 12. The rigid plate component 42 can ensure the bearing capacity of the plate component 40, and the flexible plate component 43 can eliminate the interference between the plate component 40 and the inner wall of the docking channel 12 during the rotation process, thereby ensuring that the rotation angle of the opening and closing component can reach 90°.

[0076] As a preferred implementation of the present application, Figure 7 and Fig.10 As shown, it also includes a mounting base 60 and an anti-foolproof member for mounting the dust bin 10.

[0077] The present application does not specifically limit the implementation of the foolproof component, and any of the following examples may be used:

[0078] Embodiment 7: The foolproof part includes a foolproof protrusion 61 provided on either the mounting base 60 or the bottom of the dust bucket 10, and a foolproof groove 50 provided on the other, and the foolproof protrusion 61 cooperates with the foolproof groove 50. When the user installs the dust bucket 10, first confirm that the foolproof protrusion 61 and the foolproof groove 50 are located on the same side, and then install the dust bucket 10 vertically downward on the mounting base 60. When the foolproof protrusion 61 cooperates with the foolproof groove 50, it means that the dust bucket 10 is installed in place. If the upper end surface of the dust bucket 10 is obviously higher than the design height after the dust bucket 10 is installed, it means that the dust bucket 10 is not installed in place. At this time, it is only necessary to properly rotate the dust bucket 10 by a certain angle to make the foolproof protrusion 61 match with the foolproof groove 50.

[0079] Embodiment 8: The foolproof member includes a foolproof protrusion 61 provided on one of the mounting base 60 and the side of the dust bin 10, and a foolproof groove 50 provided on the other, and the foolproof protrusion 61 cooperates with the foolproof groove 50. The principle is basically the same as that of embodiment 1, and will not be described in detail here.

[0080] In addition, if Figure 8 As shown, a handle 23 is provided on the upper end of the cyclone separator 20. The setting of the handle 23 facilitates the taking and placing of the dust bin 10. The handle 23 set above the cyclone separator 20 rotates in the front and rear directions. The position of the handle 23 can roughly indicate the placement direction of the dust bin 10, thereby playing a certain indicating role and avoiding the misplaced installation of the dust bin 10.

[0081] Reference Figure 7 and Figure 8 A dust collecting pile includes a pile body 70 and a negative pressure source 30, wherein the negative pressure source 30 is connected to an exhaust channel 31, wherein the negative pressure source 30 and the exhaust channel 31 are arranged below the docking channel 12, and a seal is fixed to the docking portion of the exhaust channel 31. After the negative pressure source 30 is started, the negative pressure source 30 inhales air through the exhaust channel 31, and the airflow carries garbage debris from the dust inlet 11 into the inner cavity of the dust bin 10, and the garbage debris is stagnant in the inner cavity of the dust bin 10 after being filtered by the cyclone separator 20. After the airflow passes through the cyclone separator 20, it passes through the exhaust channel 21 and the docking channel 12 from top to bottom, and then enters the exhaust channel 31 and is finally discharged from the exhaust end of the negative pressure source 30. The setting of the seal can seal the docking portion to prevent the airflow from leaking from the docking portion and causing a loss of suction. Moreover, the seal is arranged on the exhaust channel 31, and there is no risk of the seal detaching due to cleaning the dust bin 10. It should also be noted that the cyclone separator 20 in the above test method is a mature existing technology, and the negative pressure source 30 is a negative pressure high-speed fan structure, which is also a mature existing technology, and their working principles will not be described in detail.

[0082] Anything not described in this application can be achieved by adopting or drawing on existing technologies.

[0083] The various embodiments in this specification are described in a progressive manner, and the same or similar parts between the various embodiments can be referenced to each other, and each embodiment focuses on the differences from other embodiments.

[0084] The above is only an embodiment of the present application and is not intended to limit the present application. For those skilled in the art, the present application may have various changes and variations. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the present application should be included in the scope of the claims of the present application.
