Description
Technical Field
[0001] This utility model belongs to the field of waste treatment technology, and relates to a garbage basket and a cleaning robot. Background Technology
[0002] Cleaning the swimming pool surface is the first step in the overall cleaning and maintenance of the swimming pool, because most of the trash and scum first fall to the surface and float on the water. If it is not cleaned in time and frequently, after a few hours, this trash and scum will sink to the bottom or spread to a wider area, making the cleaning and maintenance of the swimming pool more difficult.
[0003] Therefore, swimming pool surface cleaning robots, or simply water surface cleaners, have appeared on the market. These robots can be used to clean debris and scum from the water surface. Water surface cleaners have a buoyancy-providing body and a propulsion device that drives the body to move on the water surface. Inside the body of the water surface cleaner is a cavity housing a collection basket for collecting debris and scum. This basket has an opening at the front to allow water to enter, while the surrounding and bottom structures have filters to allow water to flow out. When the propulsion device propels the body forward on the water surface, the water flows towards the body, through the opening, and into the collection basket. If there is debris or scum floating on the surface, it will be carried into the basket by the water flow. However, when the water flows out of the basket through the filter, the debris and scum are trapped inside. This collection basket can be removed from the body, the collected debris and scum cleaned out, and then placed back into the water surface cleaner.
[0004] An impeller can be installed at the front opening of this garbage collection basket. Driven by a motor, the impeller blades sweep water into the basket, helping garbage and scum to enter more easily. When the water cleaner needs to turn or reverse, the water flow changes direction, moving away from the basket and carrying away any floating garbage or scum near the opening. While the rotating impeller prevents larger debris, such as leaves, from flowing back onto the surface, it is less effective at preventing small debris, such as insects, and scum from overflowing, thus reducing the cleaning efficiency. To improve the efficiency of collecting garbage and scum, a device is needed to prevent overflow. Summary of the Invention
[0005] The purpose of this invention is to address the aforementioned problems in the existing technology by proposing a trash can and a cleaning robot.
[0006] The objective of this utility model can be achieved through the following technical solution: a garbage basket, comprising:
[0007] A base having a waste chamber and an opening, the opening being connected to the waste chamber;
[0008] An impeller is rotatably connected to the base and disposed in the opening, and the impeller can rotate in a first direction or a second direction, the first direction being opposite to the second direction;
[0009] A leak-proof component includes a one-way rotating member and a baffle. The baffle can be moved to an open position or a covered position. The one-way rotating member is rotatably connected to the impeller in one direction. The baffle is connected to the one-way rotating member and disposed at the opening. When the baffle is in the open position, the opening is exposed. When the baffle is in the covered position, it blocks the opening together with the impeller.
[0010] When the impeller rotates in the first direction, the one-way rotating member is rotatable relative to the impeller. When the impeller rotates in the second direction, the one-way rotating member is fixed relative to the impeller, thereby causing the impeller to drive the baffle to move from the open position to the shielded position through the one-way rotating member.
[0011] In the aforementioned type of garbage basket, the one-way rotating component is a one-way bearing. The impeller is connected to the inner ring of the one-way bearing, and the baffle is connected to the outer ring of the one-way bearing. When the impeller rotates in the first direction, the outer ring of the one-way bearing can rotate relative to its inner ring. When the impeller rotates in the second direction, the outer ring of the one-way bearing is fixed relative to its inner ring.
[0012] In the aforementioned type of trash can, the base is further provided with a first limiting part, and the baffle can contact the first limiting part. When the baffle contacts the first limiting part, it is located in the open position. When the impeller rotates in the first direction, the first limiting part restricts the baffle from moving away from the shielded position.
[0013] The aforementioned type of trash can also includes a reset component, which is used to move the baffle from the covered position to the open position.
[0014] In the aforementioned type of trash can, the resetting element is a torsion spring, one end of which is connected to the base, and the other end of which is connected to the baffle.
[0015] In the aforementioned type of trash basket, the base is further provided with a second limiting part, which is located at the opening. The baffle can contact the second limiting part, and when the baffle contacts the second limiting part, it is located in the shielding position.
[0016] The aforementioned type of trash can also includes a drive unit, which is connected to the base, and the impeller is connected to the drive unit. The drive unit can drive the impeller to rotate in a first direction or a second direction.
[0017] The aforementioned type of trash can also includes a controller, which is electrically connected to the drive unit. The controller is used to sense changes in the current of the drive unit and control the drive unit to operate or stop.
[0018] In one of the aforementioned trash cans, the baffle includes a connecting arm and a baffle plate. One end of the connecting arm is connected to the one-way rotating member, and the other end of the connecting arm is detachably connected to the baffle plate.
[0019] A cleaning robot is also provided, including the aforementioned trash can, and further including: a robot body, with the base connected to the robot body.
[0020] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0021] 1. The anti-leakage component allows the unidirectional rotating parts to idle when the impeller rotates in the direction of normal operation to collect garbage, and when the impeller rotates in the opposite direction of normal operation, it drives the baffle to block the opening, ensuring collection efficiency while preventing floating objects from overflowing again.
[0022] 2. This design makes the entire waste collection process more efficient and orderly. Through the forward and reverse rotation of the impeller and the coordinated work of the baffle and one-way bearing, it ensures that the waste can be effectively collected and there will be no abnormal situations such as spitting out.
[0023] 3. The impeller is connected to the inner ring of the one-way bearing, and the baffle is connected to the outer ring of the one-way bearing. Therefore, when the impeller rotates, it will drive the inner ring of the one-way bearing to rotate, and the outer ring of the one-way bearing will rotate or not depending on the direction of rotation.
[0024] 4. When the baffle is in contact with the first limiting part, it is in the open position. At this time, when the impeller continues to rotate in the first direction, the first limiting part restricts the baffle from moving away from the shielded position.
[0025] 5. One end of the torsion spring is connected to the base, and the other end of the torsion spring is connected to the baffle. When the baffle moves to the shielded position, the torsion spring accumulates elastic potential energy. Under the condition that it is not constrained by external force, the torsion spring drives the baffle to return from the shielded position to the open position.
[0026] 6. When the baffle contacts the second limiting part, it is in the shielded position. At this time, when the impeller continues to rotate in the second direction, the second limiting part restricts the baffle from moving away from the open position. Attached Figure Description

Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.
[0038] Furthermore, the technical solutions of the various embodiments of this utility model can be combined with each other, but only if they are based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or cannot be implemented, it should be considered that such combination of technical solutions does not exist and is not within the scope of protection claimed by this utility model.
[0039] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
[0040] like Figures 1-6 As shown, a trash can includes: a base 100, an impeller 200, and a leak-proof component.
[0041] The base 100 is provided with a waste chamber 110 and an opening 120, and the opening 120 is connected to the waste chamber 110.
[0042] The impeller 200 is rotatably connected to the base 100 and disposed in the opening 120. The impeller 200 can rotate in a first direction or a second direction, the first direction being opposite to the second direction.
[0043] The leak-proof component includes a one-way rotating component and a baffle. The baffle can be moved to an open position or a covered position. The one-way rotating component is rotatably connected to the impeller 200. The baffle is connected to the one-way rotating component and is disposed at the opening 120. When the baffle is in the open position, the opening 120 is exposed. When the baffle is in the covered position, it and the impeller 200 together block the opening 120.
[0044] Specifically, when the impeller 200 rotates in the first direction, the one-way rotating member is rotatable relative to the impeller 200. When the impeller 200 rotates in the second direction, the one-way rotating member is fixed relative to the impeller 200, thereby causing the impeller 200 to drive the baffle to move from the open position to the shielded position through the one-way rotating member.
[0045] In this embodiment, the anti-leakage component allows the impeller 200 to rotate freely in the direction of normal operation for collecting waste, while the impeller 200 rotates in the opposite direction of normal operation, causing the baffle to block the opening 120, thus ensuring collection efficiency while preventing floating objects from overflowing again.
[0046] It is worth noting that this design makes the entire waste collection process more efficient and orderly. Through the forward and reverse rotation of the impeller 200 and the coordinated work of the baffle and one-way bearing 310, it ensures that the waste can be effectively collected and there will be no abnormal situations such as spitting out.
[0047] like Figures 1-6 As shown, based on the above embodiment, the one-way rotating component is a one-way bearing 310, the impeller 200 is connected to the inner ring of the one-way bearing 310, and the baffle is connected to the outer ring of the one-way bearing 310. When the impeller 200 rotates in the first direction, the outer ring of the one-way bearing 310 can rotate relative to its inner ring. When the impeller 200 rotates in the second direction, the outer ring of the one-way bearing 310 is fixed relative to its inner ring.
[0048] Specifically, the one-way bearing 310 is a mechanical device that allows a shaft to rotate freely in one direction while being locked in another. It mainly utilizes the interaction of internal components (such as rollers, wedges, or springs) in different rotational directions to achieve unidirectional motion.
[0049] In this embodiment, the impeller 200 is connected to the inner ring of the one-way bearing 310, and the baffle is connected to the outer ring of the one-way bearing 310. Therefore, when the impeller 200 rotates, it will drive the inner ring of the one-way bearing 310 to rotate, and the outer ring of the one-way bearing 310 will rotate or not depending on the direction of rotation.
[0050] like Figures 1-6 As shown, based on the above embodiment, the base 100 is further provided with a first limiting part 130, and the baffle can contact the first limiting part 130. When the baffle contacts the first limiting part 130, it is located in the open position.
[0051] In this embodiment, when the baffle is in contact with the first limiting part 130, it is in the open position. At this time, when the impeller 200 continues to rotate in the first direction, the first limiting part 130 restricts the baffle from moving away from the shielded position.
[0052] like Figures 1-6 As shown, based on the above embodiment, a reset member is also included, which is used to drive the baffle to move from the shielded position to the open position.
[0053] In this embodiment, the specific structure of the reset member is not limited. It can be a spring, a torsion spring 400, or other components, as long as the reset member can drive the baffle to move from the covered position to the open position.
[0054] like Figures 1-6 As shown, based on the above embodiment, the reset component is a torsion spring 400, one end of the torsion spring 400 is connected to the base 100, and the other end of the torsion spring 400 is connected to the baffle.
[0055] In this embodiment, one end of the torsion spring 400 is connected to the base 100, and the other end of the torsion spring 400 is connected to the baffle. When the baffle moves to the shielded position, the torsion spring 400 accumulates elastic potential energy. Under the condition that it is not constrained by external force, the torsion spring 400 drives the baffle to return from the shielded position to the open position.
[0056] like Figures 1-6 As shown, based on the above embodiment, the base 100 is further provided with a second limiting part 140, the second limiting part 140 is provided in the opening 120, the baffle can contact the second limiting part 140, and the baffle is located in the shielding position when it contacts the second limiting part 140.
[0057] In this embodiment, when the baffle is in contact with the second limiting part 140, it is in the shielded position. At this time, when the impeller 200 continues to rotate in the second direction, the second limiting part 140 restricts the baffle from moving away from the open position.
[0058] like Figures 1-6 As shown, based on the above embodiment, a driving component is also included. The driving component is connected to the base 100, and the impeller 200 is connected to the driving component. The driving component can drive the impeller 200 to rotate in a first direction or a second direction.
[0059] It is worth noting that the driving component is a driving assembly including a drive motor, which can be connected through a transmission assembly. In the figure, only the drive gear 500 whose end is connected to the impeller 200 and used for output is shown, but in reality, the output shaft of the drive motor can also be directly connected to the impeller 200.
[0060] In this embodiment, the driving component can rotate in both directions to drive the impeller 200 to rotate in a first direction or a second direction.
[0061] like Figures 1-6 As shown, based on the above embodiment, a controller is also included. The controller is electrically connected to the drive unit and is used to sense the current change of the drive unit and control the operation or stop of the drive unit.
[0062] In this embodiment, the controller is used to sense the current change of the drive component and control the drive component to work or stop. Thus, when the baffle contacts the second limiting part 140, the second limiting part 140 applies force to the impeller 200, thereby causing the current of the drive component to change. At this time, the controller can control the drive component to stop working.
[0063] like Figures 1-6 As shown, based on the above embodiment, the baffle includes a connecting arm 320 and a baffle plate 330. One end of the connecting arm 320 is connected to the one-way rotating member, and the other end of the connecting arm 320 is detachably connected to the baffle.
[0064] In this embodiment, one end of the connecting arm 320 is connected to the one-way rotating member, and the other end of the connecting arm 320 is detachably connected to the baffle 330, so the baffle 330 can be replaced at any time according to actual needs.
[0065] like Figures 1-6 As shown, a cleaning robot includes a trash can and a robot body (not shown in the figure), with the base 100 connected to the robot body.
[0066] In this embodiment, the type of cleaning robot is not limited. It can be a surface cleaning robot, an underwater cleaning robot, or other cleaning robots. No specific limitation is made here.
