Description

Technical Field

[0001] This utility model relates to the field of fruit cleaning technology, specifically a fruit cleaning device. Background Technology

[0002] During fruit cultivation, pesticides such as organophosphates and pyrethroids are commonly used to control pests and diseases. These pesticides may remain on the fruit's surface. Long-term ingestion of pesticide residues that are not thoroughly washed away can lead to chronic poisoning or endocrine disorders. Therefore, washing fruit is an important step in removing pesticide residues and protecting human health.

[0003] Chinese Patent Application No. 202321756913.7 discloses a fruit washing machine, including a frame, a roller assembly mounted on the frame, and a motor for driving the roller assembly to rotate. The roller assembly includes a fixed base mounted on the frame, and the fixed base includes multiple annular seats evenly arranged along the axial direction. A primary cleaning ring and a secondary cleaning ring are sequentially annularly sleeved between each pair of adjacent annular seats. The primary and secondary cleaning rings are rotatably coupled, and the primary and secondary cleaning rings are rotated in opposite directions through a transmission device. This prevents the fruit inside the roller assembly from rolling along the inner wall of the roller, but instead causes it to roll irregularly. Combined with the spraying from the nozzles and the scrubbing of the brush structure inside the roller assembly, the dirt and sand adhering to the surface of the fruit can be better removed, thus improving the cleaning effect.

[0004] In existing and above technologies, during production, the lack of effective buffering causes frequent and irregular direct collisions between fruits as the drum rotates. This is especially true for fruits with thin and brittle skins, such as strawberries and blueberries, which are easily damaged during these collisions. This not only affects their appearance but may also accelerate spoilage and reduce their edible value. Therefore, a fruit washing device is proposed to address these issues. Utility Model Content

[0005] In order to overcome the shortcomings of the prior art and solve at least one technical problem in the background art, this utility model proposes a fruit washing device.

[0006] The technical solution adopted by this utility model to solve its technical problem is as follows: The fruit washing device of this utility model includes a motor and a washing box. The surface of the washing box is fixedly connected to a support leg and a drain outlet. The washing box is connected to a base plate through a sliding mechanism. A vertical rod is fixedly connected to the surface of the base plate. A vibrating block is slidably connected to the surface of the vertical rod. The other end of the vibrating block is slidably connected to the surface of a horizontal rod. Springs are sleeved on the surfaces of both the horizontal rod and the vertical rod. The two ends of the horizontal rod are fixedly connected to the surface of a connecting block. The connecting block is fixedly connected to the surface of the washing frame. The motor is fixedly connected to the surface of the fixing block, the fixing block is fixedly connected to the surface of the top plate, the top plate is mechanically inserted into the surface of the cleaning tank, and the surface of the top plate is provided with a limiting mechanism.

[0007] Preferably, the sliding mechanism includes a slide rod, which is fixedly connected to the inner wall of the cleaning tank, and a circular hole is provided on the surface of the bottom plate, through which the bottom plate is slidably connected to the surface of the slide rod.

[0008] Preferably, the limiting mechanism includes a limiting plate, a connecting rod is fixedly connected to the surface of the limiting plate, and the other end of the connecting rod is fixedly connected to the surface of the top plate.

[0009] Preferably, the inner wall of the cleaning tank is provided with a water inlet, and there are several water inlets.

[0010] Preferably, an overflow trough is fixedly connected to the surface of the cleaning tank, and the surface of the overflow trough has an opening. The overflow trough is designed to be inclined to the opening.

[0011] Preferably, the cleaning tank has a door on its surface, and the door is mechanically inserted into the surface of the overflow tank.

[0012] The advantages of this utility model are: 1. In operation, this utility model first requires preliminary preparation. The fruits to be cleaned are placed one by one into the cleaning frame. Then, the matching top plate is removed, aligned with the mechanical insertion slot on the edge of the cleaning frame, and pressed vertically down. Through the physical insertion structure, the connection between the top plate and the cleaning frame is firmly locked, completely eliminating the risk of the top plate detaching even during subsequent high-frequency vibrations. The top plate also prevents the fruits from jumping out of the cleaning frame during vibration. Next, the cleaning process begins. Clean water is poured into the cleaning tank until it completely submerges all the fruits in the cleaning frame. The motor is then started. After the motor starts running, it drives the transmission components and the vibrating blocks to form a high-frequency linkage. Through the coordinated action of the two... Under the same action, the washing frame will produce uniform and gentle up-down and left-right vibrations. This vibration will be transmitted to the water to form a fine water flow. The final washing process is completed entirely in water. The water flow will continuously wash the surface of the fruit with the vibration of the washing frame, peeling off dirt, pesticide residues and other contaminants from the fruit peel. More importantly, the water layer can play a key buffering role. When the fruit is slightly displaced or comes into contact due to the vibration, the water flow will absorb the impact force of the collision, avoiding direct hard friction or violent impact between fruits or between fruits and the washing frame wall. This fundamentally ensures that the washed fruit retains its intact appearance, achieving both cleaning effect and minimizing the problem of skin damage.

[0013] 2. When this utility model is in operation, after the fruit is washed, no complicated tools are needed. Simply hold the washing frame with both hands and gently apply a uniform upward pull. The washing frame will slide smoothly along the pre-set sliding rods on the inner wall of the washing box. The entire process does not require any strenuous prying or disassembly of parts. The washing frame can be easily and completely removed from the equipment, and the washed fruit can be poured out directly by tilting it. This is especially useful for granular fruits such as grapes and cherry tomatoes, as there is no need to pick them up one by one, greatly reducing fruit retrieval time. At the same time, the hollow structure of the washing frame can drain excess water when retrieving the fruit, preventing water droplets from dripping and soiling the operating table, further improving the user experience. In terms of equipment maintenance and lifespan, after the washing frame is completely removed, the inside of the washing box will be completely exposed. Residual dirt and impurities inside the box can be directly rinsed with clean water. The hollow mesh gaps of the washing frame can also be easily cleaned to prevent dirt accumulation and bacterial growth. If the equipment malfunctions, disassembling the washing frame provides ample space for maintenance operations, facilitating quick troubleshooting and handling of problems, reducing potential equipment failures, thereby effectively extending the overall service life of the equipment and reducing subsequent maintenance costs.

Detailed Implementation

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Example 1 Please see Figure 1-4 As shown, a fruit washing device includes a motor 2 and a washing tank 9. The surface of the washing tank 9 is fixedly connected with a support leg 7 and a drain outlet 11. The washing tank 9 is connected to a base plate 16 through a sliding mechanism. A vertical rod 17 is fixedly connected to the surface of the base plate 16. A vibrating block 15 is slidably connected to the surface of the vertical rod 17. The other end of the vibrating block 15 is slidably connected to the surface of the horizontal rod 19. Springs are sleeved on the surfaces of both the horizontal rod 19 and the vertical rod 17. The two ends of the horizontal rod 19 are fixedly connected to the surface of the connecting block 14. The connecting block 14 is fixedly connected to the surface of the cleaning frame 8. The motor 2 is fixedly connected to the surface of the fixing block 1, the fixing block 1 is fixedly connected to the surface of the top plate 3, the top plate 3 is mechanically inserted into the surface of the cleaning tank 9, and the surface of the top plate 3 is provided with a limiting mechanism. During operation, the initial preparation is performed by placing the fruits to be washed one by one into the washing frame 8. Next, the matching top plate 3 is taken out and aligned with the mechanical insertion slot on the edge of the washing frame 8. The top plate 3 is then pressed down vertically. This physical insertion structure firmly locks the connection between the top plate 3 and the washing frame 8, completely eliminating the risk of the top plate 3 detaching even during subsequent high-frequency vibrations. The top plate 3 also prevents the fruits from jumping out of the washing frame 8 during vibration. The washing process then begins by filling the washing tank 9 with clean water until the water level completely covers all the fruits in the washing frame 8. The motor 2 is then started. Once running, the motor 2 drives the transmission component and the vibrating block 15 to form a high-frequency linkage. With the combined action of the washing mechanism, the washing frame 8 will produce uniform and gentle up-down and left-right vibrations. These vibrations will be transmitted to the water to form fine water flow. The final washing process is completed entirely in water. The water flow will continuously wash the surface of the fruit with the vibration of the washing frame 8, removing dirt, pesticide residues and other contaminants from the fruit peel. More importantly, the water layer can play a key buffering role. When the fruit is slightly displaced or comes into contact due to the vibration, the water flow will absorb the impact force, avoiding direct hard friction or violent impact between fruits or between fruits and the walls of the washing frame 8. This fundamentally ensures that the washed fruit retains its intact appearance, achieving both cleaning effect and minimizing the problem of skin damage.

[0019] The sliding mechanism includes a slide rod 4, which is fixedly connected to the inner wall of the cleaning tank 9. A round hole 18 is provided on the surface of the bottom plate 16, and the bottom plate 16 is slidably connected to the surface of the slide rod 4 through the round hole 18. During operation, once the fruit is washed, no complicated tools are needed. Simply hold the washing frame 8 with both hands and gently apply even upward pulling force. The washing frame 8 will then slide smoothly along the pre-set sliding rod 4 on the inner wall of the washing tank 9. The entire process requires no effort to pry or disassemble parts, allowing the washing frame 8 to be easily and completely removed from the equipment. The washed fruit can then be tilted and poured out directly, especially for granular fruits such as grapes and cherry tomatoes, eliminating the need to pick them up one by one, significantly reducing fruit retrieval time. At the same time, the hollow structure of the washing frame 8 allows excess water to drain during fruit retrieval, preventing water droplets from dripping and soiling the worktable, further enhancing the user experience. In terms of equipment maintenance and lifespan assurance, once the washing frame 8 is completely removed, the interior of the washing tank 9 is fully exposed. Residual dirt and impurities inside the tank can be directly rinsed with clean water, and the hollow mesh gaps of the washing frame 8 can be easily cleaned to prevent dirt accumulation and bacterial growth. If minor equipment malfunctions occur, disassembling the washing frame 8 provides ample space for maintenance operations, facilitating quick troubleshooting and problem handling, reducing potential equipment failures, and thus effectively extending the overall equipment lifespan and reducing subsequent maintenance costs.

[0020] The limiting mechanism includes a limiting plate 13, a connecting rod 12 is fixedly connected to the surface of the limiting plate 13, and the other end of the connecting rod 12 is fixedly connected to the surface of the top plate 3. During operation, the limiting plate 13 is designed to fit the inner wall of the washing frame 8, and its edges are equipped with flexible anti-slip rubber strips. Before washing, when the top plate 3 is closed, the limiting plate 13 extends into the washing frame 8. After water is added to the washing tank 9 and vibration washing is started, some less dense fruits (such as apples, pears, cherry tomatoes, etc.) tend to float upwards due to buoyancy. Without the restraint of the limiting plate 13, these fruits would float on the surface and not be fully submerged. The limiting plate 13 extending into the washing frame 8 forms a "physical barrier," applying slight and even pressure from above to hold the floating fruits firmly in place. By firmly confining the fruit to the underwater area, each piece of fruit is forced to be enveloped in the water flow, preventing any partial exposure. The fruit is completely submerged in the water, allowing the fine water flow generated by the vibration to thoroughly wash the surface of the fruit peel, effectively removing dirt, pesticide residues, and other contaminants. If the fruit floats on the surface, the exposed parts cannot come into contact with the water flow, creating blind spots and resulting in incomplete cleaning. The limiting plate 13 prevents the fruit from floating, ensuring that all fruit receives uniform vibration and cleaning in the water. Whether it is dirt in the crevices of the peel or adhering to the surface, it can be fully carried away by the water flow, fundamentally guaranteeing the consistency and thoroughness of the cleaning effect.

[0021] The inner wall of the cleaning tank 9 is provided with water inlets 10, and there are several water inlets 10; During operation, the equipment's water inlet system is activated simultaneously, continuously injecting clean water through the pre-set water inlets 10 on the inner wall of the washing tank 9. These inlets 10 are distributed at multiple angles on the lower part of the side wall of the washing tank 9, allowing the water to flow into the tank in a gentle, diffused manner. This prevents the water flow from disrupting the vibration rhythm of the washing frame 8 due to excessive force, and also avoids direct impact on the fruit, which could damage the skin. This achieves "continuous washing and continuous water intake." The dynamic water circulation system allows mud and dirt peeled from the fruit surface to gradually dissolve into the water. If the water is not changed in time, these contaminants may re-adhere to the fruit peel, causing secondary pollution. The continuously injected clean water dilutes the concentration of wastewater in the tank and promotes a slow flow, allowing the wastewater containing contaminants to naturally drain to the top of the washing tank. This is equivalent to "changing the water" in real time during the washing process, keeping the water in the tank clean at all times. This design of continuous water intake on the inner wall ensures that each piece of fruit is always in contact with clean water throughout the entire washing cycle. This not only improves the removal rate of pesticide residues and stubborn stains but also prevents the accumulation of dirt from affecting the washing efficiency, ultimately ensuring that the washed fruit is both clean and hygienic.

[0022] An overflow trough is fixedly connected to the surface of the cleaning tank 9. The surface of the overflow trough has an opening. The overflow trough is designed to be inclined to the opening. During operation, in the dynamic cleaning mode with continuous water intake, wastewater containing mud, fruit peel impurities, and pesticide residues will gradually flow towards the overflow port at the top of the cleaning tank 9 due to the propulsion of the newly injected clean water and the density difference of the wastewater itself. The top edge of the cleaning tank 9 has a pre-set annular overflow trough, which allows the wastewater to naturally flow into the overflow trough, achieving "continuous intake of clean water and real-time discharge of wastewater". The dynamic circulation eliminates the need for manual drain valve operation, ensuring fully automated operation. The overflow trough at the top of the washing tank 9 is seamlessly connected to the overflow tank. After the sewage flows into the overflow trough, it flows along the inclined slope of the inner wall of the overflow trough. The overflow trough adopts a scientific tilt angle design of 15° to 20°, which can ensure that the sewage flows quickly without stagnation and avoid splashing caused by excessive water flow. The end of the overflow trough is directly connected to the trough opening, and all sewage will eventually be collected in the external sewage collection bucket or sewer through the trough opening, realizing centralized collection of waste. This design not only avoids sewage being discharged randomly and soiling the operating table, but also facilitates the unified treatment of sewage in the future (such as filtering impurities before discharge). It meets the cleanliness and hygiene standards and reduces the workload of later cleaning, making the entire washing process from "washing fruit" to "draining sewage" a complete closed loop.

[0023] Example 2 Please see Figure 5 As shown in the first embodiment, as another implementation of this utility model, the cleaning tank 9 is provided with a door 20 on its surface, and the door 20 is mechanically inserted into the surface of the overflow tank. During operation, the equipment's door 20 is sized to perfectly fit the edge of the washing tank 9. A flexible silicone sealing ring is wrapped around the edge of the door. When the equipment is not in use, closing the door 20 inward and fastening the buckle will cause the sealing ring to fit tightly against the outer wall of the washing tank 9, forming a complete sealing barrier. This prevents dust and other impurities floating in the air from falling into the tank and adhering to the washing frame 8, the inner wall, or the vibration components. This not only causes contamination but may also adhere to the fruit with the water flow during the next use. When the door 20 is closed, it completely isolates dust and impurities from the external environment, preventing them from entering the washing tank 9 and ensuring that the inside of the tank remains clean every time the equipment is turned on, eliminating the need for additional cleaning.
