Description

Technical Field

[0001] This utility model relates to the field of sink cleaning technology, and in particular to a cleaning device for cleaning sinks. Background Technology

[0002] Sinks are prone to accumulating stubborn stains such as oil and limescale during daily use. Current cleaning methods mainly rely on manual scrubbing or soaking in water. Manual cleaning is inefficient and struggles to thoroughly remove residue from the sink walls, especially in deep sinks and corner areas. Soaking consumes a large amount of water and requires secondary cleaning afterward, failing to achieve immediate cleaning. While some products use chemical cleaning agents, there is a risk of corrosion to the sink surface and water contamination. In recent years, although a few self-cleaning technologies have emerged, they are mostly limited to localized cleaning of the drain or simple spray systems, lacking proactive cleaning solutions for the sink walls. Utility Model Content

[0003] The technical problem to be solved by this utility model is to provide a cleaning device for cleaning sinks that can efficiently self-clean the walls of sinks, reduce water consumption, and eliminate the need for manual intervention, in light of the current state of the technology.

[0004] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: a cleaning device for cleaning sinks, used to clean the walls of sinks, comprising:

[0005] case;

[0006] A cleaning cylinder assembly includes a cylinder support and a cleaning cylinder rotatably mounted on the cylinder support. The cylinder support is mounted on the housing. The cleaning cylinder can be driven by a first drive mechanism to rotate around its own axis and clean the garbage on the wall of the sink during the rotation.

[0007] It also includes a cleaning cylinder movement device, wherein the cylinder support is movably mounted on the housing, and the power output end of the cleaning cylinder movement device is connected to the cylinder support, for driving the cylinder support and the cleaning cylinder mounted on the cylinder support to move closer to or further away from the surface to be cleaned, so as to adjust the force applied by the cleaning cylinder to the wall of the water tank.

[0008] To simplify the structure of the cleaning cylinder movement device, it includes a second drive mechanism, a power transmission assembly, and a reset component. The power transmission assembly is located between the power output end of the second drive mechanism and the cylinder support, transmitting power from the second drive mechanism to the cylinder support to move it closer to the surface to be cleaned. The reset component acts on the cylinder support, ensuring it always tends to move away from the surface to be cleaned. Through the coordinated action of the second drive mechanism, the power transmission assembly, and the reset component, precise displacement control of the cleaning cylinder is achieved. Simultaneously, the reset component ensures the cleaning cylinder automatically returns to its original position when there is no drive, improving operational convenience and safety.

[0009] A power transmission assembly refers to a mechanical component that transmits power from a drive source to an actuator, such as gears, racks, chains, belts, or other components or combinations thereof. To ensure the stability of the vertical movement of the cylindrical support, the second drive mechanism includes a second drive motor. The power transmission assembly includes a transmission gear and a first and second transmission rack arranged vertically at intervals. The transmission gear is connected to the output shaft of the second drive motor and is driven to rotate by the second drive motor. The transmission gear is located between the first and second transmission racks and meshes with both of them simultaneously. During forward and reverse rotation, it drives the first and second transmission racks to reciprocate horizontally. The cylindrical support includes two connecting arms arranged side by side. The two ends of the first and second transmission racks that are far apart from each other are engaged with the two connecting arms through guide inclined surfaces, thereby converting the horizontal movement of the first and second transmission racks into the vertical movement of the cylindrical support. The design employs a transmission gear and double rack meshing mechanism, along with a guide ramp, to efficiently convert horizontal reciprocating motion into vertical motion. This ensures smooth movement and precise positioning of the cleaning cylinder, resulting in a more compact and efficient overall structure for the cleaning device.

[0010] To ensure the stability of the cylinder support's vertical movement, the housing has vertically extending limiting grooves, and the cylinder support has vertically extending limiting sliders. The limiting sliders are slidably limited within the limiting grooves. This cooperative design of the limiting grooves and sliders enhances the guiding nature of the cylinder support, ensuring stable movement of the cleaning cylinder along a fixed path and preventing movement deviations.

[0011] As an improvement, the cylinder support has two limiting sliders, which are respectively located on the two connecting arms, and there are also two corresponding limiting sliders.

[0012] The aforementioned reset component can employ various existing technologies, including various elastic elements such as compression springs, torsion springs, and leaf springs. However, in order to better cooperate with the aforementioned cylinder support, the reset component is a compression spring, which rests between the cylinder support and the housing.

[0013] As an improvement, the cylinder support includes two side-by-side connecting arms. The first drive mechanism includes a first drive motor. The cleaning cylinder is arranged between the two connecting arms. The first drive motor is mounted on one of the connecting arms and housed inside the cleaning cylinder. The output shaft of the first drive motor is connected to a transmission shaft coaxially located inside the cleaning cylinder. Integrating the first drive motor into the cleaning cylinder optimizes the spatial layout, reduces rotational inertia, and improves the rotational stability of the cleaning cylinder.

[0014] To promptly remove the debris picked up by the cleaning drum, the housing includes a main body and a debris collection box within the main body. The debris collection box has a debris inlet on the side facing the cleaning drum, extending along the length of the cleaning drum. Cleaning combs are located along the upper edge of the debris inlet. During the rotation of the cleaning drum, debris on its outer perimeter is scraped off by the cleaning combs and falls into the debris collection box. The debris collection box, in conjunction with the cleaning combs, efficiently removes and collects debris from the surface of the cleaning drum, reducing the risk of secondary contamination during the cleaning process.

[0015] Considering the problem that dry friction of the cleaning cylinder can easily lead to low cleaning efficiency, a water filling device is also included for adding water to the outer peripheral wall of the cleaning cylinder.

[0016] As an improvement, the water supply device includes a water storage tank, a water pump, and a water outlet plate. The water outlet plate is disposed on the housing and has water outlet holes arranged sequentially along the length direction of the cleaning cylinder. The water storage tank is connected to the water outlet plate, and the water pump is disposed in the water flow path between the water storage tank and the water outlet plate to pump water from the water storage tank to the water outlet plate. The evenly distributed water outlet holes on the water outlet plate ensure that the water flow uniformly covers the surface of the cleaning cylinder, reducing frictional resistance, improving cleaning effect, and extending the device's lifespan.

[0017] Compared with existing technologies, the advantages of this invention are as follows: This invention utilizes the synergistic effect of a rotating cleaning cylinder and an adaptive pressure adjustment system, employing the principle of mechanical friction to efficiently remove stubborn stains. Compared to traditional soaking methods, it effectively reduces water consumption and avoids the risk of corrosion to the tank surface by chemical cleaning agents. Furthermore, the dynamic displacement mechanism of the cylinder support allows for different pressure levels on the tank walls, with stronger pressure levels effectively cleaning deep areas such as the bottom and corners that are difficult to reach with traditional tools, ensuring comprehensive cleaning coverage of the entire tank. This cleaning device can move automatically on the bottom of the tank or be manually dragged by the user, and can also be manually dragged along the surrounding walls, improving the user's tank cleaning efficiency and achieving intelligent and low-consumption tank cleaning, making it particularly suitable for high-frequency use scenarios such as kitchens and laboratories.

[0027] The present invention will be further described in detail below with reference to the accompanying drawings and embodiments.

[0028] In the specification and claims of this utility model, terms indicating direction, such as "front," "rear," "upper," "lower," "left," "right," "side," "top," and "bottom," are used to describe various exemplary structural parts and elements of this utility model. However, the use of these terms is merely for the purpose of explanation and is based on the exemplary orientations shown in the accompanying drawings. Since the embodiments disclosed in this utility model can be arranged in different orientations, these terms indicating direction are for illustrative purposes only and should not be regarded as limitations. For example, "upper" and "lower" are not necessarily limited to directions opposite to or consistent with the direction of gravity.

[0029] Figures 1-9 A preferred embodiment of the cleaning device for cleaning a sink according to this utility model is shown. The cleaning device a for cleaning a sink in this embodiment includes a housing 1, a cleaning cylinder assembly, a cleaning cylinder movement device, a waste collection box 12, and a water filling device. The housing 1 consists of a housing body 11 and a detachable cover 111. The bottom of the housing body 11 can be equipped with casters (not shown in the drawings) to facilitate automatic or manual movement along the bottom wall 61 of the sink 6 (or, in the case of manual movement, along the side wall of the sink). The housing 1 has an internal mounting cavity for accommodating the various functional components.

[0030] See Figures 7-9 The cleaning cylinder assembly includes a cylinder support 21 and a cleaning cylinder 2. The cylinder support 21 consists of two parallel connecting arms 212, which are fixed by a transverse connecting arm. The cleaning cylinder 2 is transversely installed between the two connecting arms 212, and its two ends are rotatably connected to the connecting arms 212 via rotating components (such as bearings). Alternatively, rotating components can be omitted, meaning the ends of the cleaning cylinder 2 can be suspended, with only the connecting arms providing cover. The first drive mechanism includes a first drive motor 3, which is embedded inside the cleaning cylinder 2, and its output shaft is connected to the coaxial transmission shaft 211 of the cleaning cylinder 2. When the first drive motor 3 is energized, it drives the cleaning cylinder 2 to rotate around its own axis, using a wiping material 20 (such as nylon bristles or a rubber scraper) on the outer surface of the cleaning cylinder 2 to mechanically scrape the stains on the bottom wall 61 of the sink 6.

[0031] The cleaning cylinder motion device includes a second drive mechanism, a power transmission assembly, and a reset component 45. The second drive mechanism includes a second drive motor 41, fixed to the inner wall of the housing 1. The power transmission assembly includes a transmission gear 42, a first transmission rack 431, and a second transmission rack 432. The first transmission rack 431 and the second transmission rack 432 are arranged parallel vertically, and each of the two opposite sidewalls of the first transmission rack 431 and the second transmission rack 432 has a toothed section. The transmission gear 42 is located between the two and is coaxially connected to the output shaft of the second drive motor 41. When the second drive motor 41 rotates forward and reverse, the transmission gear 42 rotates synchronously, driving the first transmission rack 431 and the second transmission rack 432 to move towards or away from each other in the horizontal direction. The inner sides of the ends of the two connecting arms 212 are provided with guide slopes 44, and the ends of the first transmission rack 431 and the second transmission rack 432 are also provided with guide slopes 44 with the same inclination direction. When the second drive motor 41 rotates in the forward direction, the first transmission rack 431 and the second transmission rack 432 move in opposite directions. The horizontal movement of the racks is converted into vertical displacement of the connecting support arm 212 through the guide inclined surface 44, thereby driving the cleaning cylinder 2 closer to the wall of the water tank 6 and increasing the force applied by the cleaning cylinder 2 to the wall of the water tank 6. The reset component 45 is a compression spring, which is sleeved between the cylinder support 21 and the housing 1. When the second drive motor 41 rotates in the reverse direction, driving the first transmission rack 431 and the second transmission rack 432 to move towards each other, the pressure applied by the guide inclined surface 44 at the ends of the two transmission racks to the guide inclined surface 44 of the cylinder support 21 changes, and correspondingly, the compression degree of the reset spring also changes. The reset spring can push the cylinder support 21 to reset to the set position in time, ensuring that the cleaning cylinder 2 resets in time without jamming.

[0032] The first transmission rack 431 and the second transmission rack 432 move different distances in the horizontal direction, and the force applied by the cleaning cylinder 2 to the wall of the water tank 6 is also different. Since the wiping material 20 of the cleaning cylinder 2 has a certain compressive elasticity, it can also be understood that the interference between the cleaning cylinder 2 and the wall of the water tank 6 is different. Specifically, the cleaning device can divide the cleaning level into low, medium and high according to the above-mentioned interference. This solution can adjust the downward pressure of the cleaning cylinder 2 on the ground. Under the same water output, the difference in cleaning effect due to different ground pressure can be used as the level perception.

[0033] See Figure 4 The housing 1 has vertically extending limiting grooves 122 on both sides, which can be specifically set on the left and right sides of the garbage collection box 12. Two connecting arms 212 are correspondingly provided with vertically extending limiting sliders 2120. The limiting sliders 2120 are embedded in the grooves, limiting the cylinder support 21 to move only in the vertical direction, preventing horizontal deviation.

[0034] See Figure 5The housing 1 has a recess 10 on one side of its bottom, and the cleaning cylinder 2 is disposed in the recess 10. The waste collection box 12 is located on one side of the cleaning cylinder 2 and, together with other components of the housing 1, defines the recess 10. The side wall of the recess 10 facing the cleaning cylinder 2 is also constructed as an arc-shaped wall. A long strip-shaped waste inlet 120 is provided at the top of the arc-shaped wall of the waste collection box 12, the length of which matches the length of the cleaning cylinder 2. Cleaning comb teeth 121 are installed on the upper edge of the waste inlet 120, with the tips of the comb teeth contacting the surface of the cleaning cylinder 2. When the cleaning cylinder 2 rotates, the attached dirt is scraped off by the comb teeth and falls into the collection box through the waste inlet 120. The waste collection box 12 is detachable for easy cleaning by the user.

[0035] See Figure 4 and Figure 5 The water supply device includes a water storage tank 13, a water pump 14, and a water outlet plate 15. The water storage tank 13 is embedded in the housing 1 and is connected to the water outlet plate 15 via a water pipe. Specifically, the water storage tank 13 is located on the side of the garbage collection box 12 away from the cleaning cylinder 2. The water outlet plate 15 is located above the cleaning cylinder 2, specifically on the side relatively directly above and biased towards the garbage inlet 120. The interior of the water outlet plate 15 is hollow, forming a water passage. The side wall of the water outlet plate 15 facing the cleaning cylinder 2 has multiple water outlet holes 150 arranged along the length of the cleaning cylinder 2. After the water pump 14 is started, it delivers water from the water storage tank 13 to the water outlet plate 15, and the water flow is evenly sprayed onto the surface of the cleaning cylinder 2, reducing frictional resistance and enhancing the cleaning effect.

[0036] This embodiment utilizes the synergistic effect of a rotating cleaning cylinder 2 and an adaptive pressure adjustment system. By leveraging the principle of mechanical friction, it efficiently removes stubborn stains, significantly reducing water consumption compared to traditional soaking methods and avoiding the risk of corrosion to the tank surface from chemical cleaning agents. Furthermore, the dynamic displacement mechanism of the cylinder support 21 allows for different pressure settings on the tank walls of the sink 6. Higher pressure settings effectively clean deep areas such as the bottom and corners that are difficult to reach with traditional tools, ensuring comprehensive cleaning coverage of the entire sink 6. This cleaning device can move automatically on the bottom of the sink 6 or be manually dragged by the user, and the surrounding walls can also be manually moved, improving the user's cleaning efficiency and achieving intelligent and low-consumption cleaning of the sink 6. It is particularly suitable for high-frequency use scenarios such as kitchens and laboratories.

[0037] Based on the above embodiments, other embodiments can be obtained by replacing and improving the relevant technical features. For example, the power transmission component can use a chain and sprocket structure instead of a gear and rack. The output shaft of the second drive motor 41 is connected to the driving sprocket, and the driven sprockets are symmetrically arranged on both sides of the housing 1. The chain surrounds the driving sprocket and the driven sprocket, and the two sides of the chain are fixed to the first transmission rack 431 and the second transmission rack 432, respectively. When the second drive motor 41 rotates, the chain drives the rack to move horizontally, and the rest of the structure is the same as the above embodiments. This embodiment is suitable for scenarios that require a larger transmission ratio or a longer stroke.
