Description

Technical Field

[0001] This utility model relates to a fruit and vegetable cleaning equipment or a fruit and vegetable storage equipment, and more particularly to a cleaning device used in a fruit and vegetable cleaning equipment or a fruit and vegetable storage equipment. Background Technology

[0002] In the process of fruit and vegetable storage or cleaning, it is usually necessary to consider cleaning the storage equipment or cleaning equipment. Existing cleaning devices usually use simple water spray pipes for manual cleaning, which is inefficient and labor-intensive. Alternatively, they use wall-mounted spray pipes installed inside the equipment, which results in complex cleaning device layout, limited cleaning direction, high investment cost, and unsatisfactory cleaning effect.

[0003] Patent No. ZL202223111897.4, published on August 18, 2023, discloses a top-rotating cleaning device for an automatic cleaning machine. It includes a fixed support with a water inlet pipe on one side of its top surface; a cleaning ball pipe in the center of the bottom surface of the fixed support; rotating cleaning pipes around the cleaning ball pipe; and a rotating assembly on the top of the fixed support, connected to a telescopic cylinder, which in turn is connected to the cleaning ball pipe. This design uses a telescopic cylinder to raise and lower the cleaning ball pipe, and then utilizes the rotating assembly to rotate it, thus achieving 360-degree all-around cleaning of the container. It eliminates the heavy rotating chassis of traditional cleaning machines, simplifying installation, use, and maintenance. Furthermore, since there is no need to rotate the chassis and container, the rotating part consumes less energy. However, this design uses a rotating L-shaped connection to the cleaning pipe nozzles, which has limitations in terms of the single cleaning direction. Utility Model Content

[0004] This utility model provides an automatic cleaning device for the bottom and four walls of a fruit and vegetable box, which addresses the problems of low cleaning efficiency, complex cleaning device layout, limited cleaning direction, high investment cost, and unsatisfactory cleaning effect in existing fruit and vegetable cleaning or storage equipment. It offers a device with high cleaning efficiency, unrestricted cleaning direction, low investment cost, and simple layout.

[0005] The specific technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows: an automatic cleaning device for the bottom and four walls of an equipment box, characterized in that it includes a water inlet pipe, a water drive component, and a rotating spray head. One or more water drive components are connected to the water inlet pipe. Each water drive component includes a water drive impeller and a water drive planetary gear. The rotating spray head has a rotating planetary gear meshing with the water drive planetary gear. Each water drive component is connected to several rotating spray heads via its water drive planetary gear. Each rotating spray head is equipped with multiple spray nozzles, forming a rotating spray cleaning distribution structure where multiple spray nozzles work together to achieve 360-degree all-round spray cleaning in all directions (up, down, left, and right) when rotating with the rotating spray head. Under the driving action of the meshing transmission of the water drive planetary gear, the rotating planetary gear of each rotating spray head rotates 360 degrees longitudinally with the water drive planetary gear. Simultaneously, the spray nozzles on the same rotating spray head rotate 360 ​​degrees laterally (or horizontally) with the rotating planetary gear 22, thus effectively achieving an all-round 360-degree rotating automatic cleaning task without dead angles. By introducing cleaning liquid or clean water through the inlet pipe, a 360-degree all-round spray cleaning task can be achieved for the required cleaning environment or fruits and vegetables. The cleaning efficiency is high, the cleaning direction is not limited, the investment cost of the cleaning device is low, and the layout structure of the cleaning device is simple.

[0006] Preferably, each water-driven component is connected to two rotating spray heads via planetary gear drive. Each rotating spray head is equipped with at least two spray nozzles. The water outlet center axes of the two spray nozzles are on the same central axis. The water outlet center axes of the two spray nozzles on the same rotating spray head are parallel to the central axis of the water-driven component, forming a rotating spray cleaning distribution structure in which at least eight spray nozzles work together to achieve 360-degree all-round spray cleaning in all directions when rotating with the rotating spray head. This improves the layout structure of the cleaning device, making cleaning simple and effective.

[0007] Preferably, each water-driven component is connected to two rotating spray heads via planetary gear drive. Each rotating spray head is equipped with at least three spray nozzles, which are spatially distributed in a ⊥ shape. That is, the water outlet center axes of two spray nozzles on the same rotating spray head are on the same central axis and perpendicular to the water outlet center axis of the third spray nozzle on the same rotating spray head. This forms a rotating spray cleaning distribution structure in which at least ten or at least twelve spray nozzles work together with the rotating spray head to achieve 360-degree all-round spray cleaning in all directions. This improves the layout structure of the cleaning device, making cleaning simple and effective.

[0008] Preferably, the water-driven component includes a water-driven impeller, a reduction gearbox, and a water-driven planetary gear. The impeller shaft is driven by the reduction gearbox, which in turn is driven by the water-driven planetary gear. The gear face of the water-driven planetary gear meshes with the rotating planetary gear face of the spray head, enabling the spray head to follow the rotation and spray. This improves efficiency.

[0009] Preferably, the water inlet pipe connects to two water-driven components. Each water-driven component is connected to two rotating spray heads via its water-driven planetary gear transmission. Each rotating spray head is equipped with two spray nozzles. The water outlet center axes of the two spray nozzles of each rotating spray head are on the same central axis. The water outlet center axes of the two spray nozzles of each spray head are parallel to the central axis of the water-driven component, forming a rotating spray cleaning distribution structure in which eight spray nozzles work together with the rotating spray heads to achieve 360-degree all-round spray cleaning in all directions. This improves the layout structure of the cleaning device, making cleaning simple and effective.

[0010] Preferably, the water inlet pipe connects to two water-driven components. Each water-driven component is connected to two rotating spray heads via its water-driven planetary gear transmission. Each rotating spray head is equipped with three spray nozzles, which are spatially distributed in a ⊥ shape. That is, the water outlet center axes of two spray nozzles of each rotating spray head are on the same central axis and perpendicular to the water outlet center axis of the third spray nozzle of the same rotating spray head. This forms a rotating spray cleaning distribution structure in which twelve spray nozzles work together with the rotating spray heads to achieve 360-degree all-round spray cleaning in all directions. This improves the layout structure of the cleaning device, making cleaning simple and effective.

[0011] Preferably, the two water-driven components are connected to two rotating spray heads via drive transmission. The water outlet center axes of the two spray nozzles of the two sets of rotating spray heads located above the ends of the two water-driven components are at the same horizontal height or at different horizontal heights; similarly, the water outlet center axes of the two spray nozzles of the two sets of rotating spray heads located below the ends of the two water-driven components are at the same horizontal height or at different horizontal heights. This improves the layout and structure of the cleaning device, making cleaning simple and effective.

[0012] Preferably, the two water-driven components are connected to two rotating spray heads via drive transmission. The water outlet center axes of the two spray nozzles of the two sets of rotating spray heads located above the ends of the two water-driven components are at the same horizontal height or at different horizontal heights; similarly, the water outlet center axes of the two spray nozzles of the two sets of rotating spray heads located below the ends of the two water-driven components are at the same horizontal height or at different horizontal heights. This improves the layout and structure of the cleaning device, making cleaning simple and effective.

[0013] Preferably, the length of the transverse water inlet pipe branch connected to the water-driven component on the water inlet pipe is adjusted to fit the size of the equipment to be cleaned. This improves the ability to adjust the size of the equipment to be cleaned.

[0014] The beneficial effects of this invention are as follows: Each rotating planetary gear on the rotating spray head, driven by the meshing transmission of the water-driven planetary gear, rotates 360 degrees longitudinally. Simultaneously, the spray nozzles on the same rotating spray head follow the rotating planetary gear 22, performing a 360-degree transverse (or horizontal) rotation. This effectively achieves a comprehensive 360-degree rotating automatic cleaning task without blind spots. By introducing cleaning liquid or clean water through the inlet pipe, a 360-degree comprehensive spray cleaning task can be achieved for the desired cleaning environment or fruits and vegetables. The cleaning efficiency is high, the cleaning direction is unrestricted, the investment cost of the cleaning device is low, and the layout structure of the cleaning device is simple.

[0018] Example 1:

[0019] Figure 1 , Figure 2In the illustrated embodiment, an automatic cleaning device for the bottom and four walls of a device box includes a water inlet pipe, a water drive component 10, and a rotary spray head 20. The water inlet pipe 30 is connected to one or more water drive components 10 at its branch pipe 31. Each water drive component 10 includes a water drive impeller and a water drive planetary gear (the structure of the water drive component can be referenced or borrowed from existing technologies; no further drawings are shown here). The rotary spray head 20 has a rotary planetary gear 22 that meshes with the water drive planetary gear 11 (located at the drive output end of the water drive component 10). Figure 1 , Figure 2 The rotating planetary gear surface and the water-driven planetary gear surface shown are perpendicular to each other in space. Each water-driven component 10 is driven by its water-driven planetary gear 11 to connect to several rotating spray heads 20. Each rotating spray head 20 is equipped with multiple spray nozzles 21 and 21A (21A can be selected and configured according to actual spray cleaning needs), forming a rotating spray cleaning distribution structure in which multiple spray nozzles work together to achieve 360-degree all-round spray cleaning in all directions when they rotate with the rotating spray head 20. The length of the horizontal water inlet pipe branch connected to the water-driven component on the water inlet pipe is adjusted to a suitable horizontal length according to the size of the equipment to be cleaned. Under the driving action of the meshing transmission of the water-driven planetary gear 11, the rotating planetary gear 22 of each rotating spray head 20 rotates 360 degrees longitudinally with the water-driven planetary gear 11. At the same time, the spray nozzles 21 and 21A on the same rotating spray head 20 follow the rotating planetary gear 22 to perform 360 degrees transversely (or horizontally), thus effectively realizing the all-round 360-degree rotation automatic cleaning task without dead angles.

[0020] Each water-driven component 10 is connected to two rotating spray heads 20 via a planetary gear drive transmission (water-driven planetary gear 11 meshes with rotating planetary gear surface 22). Each rotating spray head 20 is equipped with at least two spray nozzles 21. The water outlet center axes of the two spray nozzles of the same rotating spray head are on the same central axis. The water outlet center axes of the two spray nozzles are parallel to the central axis of the water-driven component 10, forming a rotating spray cleaning distribution structure in which at least eight spray nozzles 21 work together to achieve 360-degree all-round spray cleaning tasks in all directions when rotating with the rotating spray head 20.

[0021] The water-driven component 10 includes a water-driven impeller, a reduction gearbox, and a water-driven planetary gear 11. The shaft of the water-driven impeller is driven to the reduction gearbox, and the reduction gearbox is driven to the water-driven planetary gear 11. The gear face of the water-driven planetary gear is meshed with the rotating planetary gear face 22 of the rotating spray head 20 to realize the rotating spray head 20 to follow the rotation and spray.

That is, the water outlet center axes of two spray nozzles from the same rotating spray head are on the same central axis and perpendicular to the water outlet center axis of the third spray nozzle from the same rotating spray head. This forms a rotating spray cleaning distribution structure where at least ten or at least twelve spray nozzles 21, 21A work together to achieve a 360-degree all-around spray cleaning task in all directions (up, down, left, and right) when rotating with the rotating spray head. Other aspects are the same as in Embodiment 1.

[0024] Example 3:

Each water-driven component 10 is connected to two rotating spray heads 20 via its water-driven planetary gear drive. Each rotating spray head is equipped with two spray nozzles 21. The water outlet center axes of the two spray nozzles of each rotating spray head 20 are on the same central axis. The water outlet center axes of the two spray nozzles of each rotating spray head are parallel to the central axis of the water-driven component 10, forming a rotating spray cleaning distribution structure in which eight spray nozzles 21 work together to achieve a 360-degree all-round spray cleaning task in all directions (up, down, left, and right) when rotating with the rotating spray head 20. Everything else is the same as in Embodiment 1.

[0026] Example 4:

[0027] Figure 1 , Figure 2 In the illustrated embodiment, the water inlet pipe 30 is connected to two water-driven components 10. Each water-driven component 10 is driven by its water-driven planetary gear 11 to connect to two rotating spray heads 20. Each rotating spray head 20 is equipped with three spray nozzles 21, 21A. The three spray nozzles 21, 21A of each rotating spray head 20 are arranged in a ⊥ shape in space. That is, the water outlet center axes of two of the spray nozzles of each rotating spray head 20 are on the same central axis and perpendicular to the water outlet center axis of the third spray nozzle 21A of the rotating spray head. This forms a rotating spray cleaning distribution structure in which twelve spray nozzles 21, 21A work together to achieve 360-degree all-round spray cleaning in all directions (up, down, left, and right) when they rotate with the rotating spray head. Other aspects are the same as in Embodiment 1.

[0028] Example 5:

Everything else is the same as in Embodiment 1.

[0032] In use, the water inlet pipe 30 is introduced from the bottom of the equipment box upwards into the equipment interior. One or more water-driven components 10 are connected to the top of the water inlet pipe via its branch pipe 31. This allows multiple spray nozzles 21 or 21, 21A (for cleaning the upper interior of the equipment, an upward-facing spray nozzle 21A can also be installed on the top of the rotating spray head 20) to work together with the rotating spray head 20 to achieve a highly efficient 360-degree all-around spray cleaning of the equipment box bottom 01 and four walls 02. Alternatively, the water inlet pipe 30 can be introduced from the top of the equipment box downwards into the equipment interior for 360-degree all-around spray cleaning.
