Description

Technical Field

[0001] This utility model relates to the field of daily necessities technology, specifically to a fruit and vegetable washing device. Background Technology

[0002] Existing fruit and vegetable washing devices include an outer shell, a drain basket rotatably disposed within the outer shell, and a cover that can be opened and closed at the opening of the outer shell. The cover has mounting holes for installing a rotating cover. Existing rotating covers are generally installed from the top of the cover into the mounting holes. Users drive the rotating cover to rotate, thereby rotating the drain basket and washing the vegetables.

[0003] However, since the rotating cover is installed on the cover body from the top of the mounting hole, the top of the rotating cover is not restrained. During high-speed rotation, the rotating cover is prone to shaking up and down or tilting. In severe cases, foreign objects may get stuck in the gap between the edge of the rotating cover and the cover body or enter the bottom of the rotating cover. This not only makes it difficult to clean, but also easily causes related safety hazards. Utility Model Content

[0004] In view of this, the present invention provides a fruit and vegetable washing device to solve the problem that the rotating cover of the existing fruit and vegetable washing device is prone to shaking up and down or tilting during high-speed rotation.

[0005] This utility model provides a fruit and vegetable washing device, including:

[0006] Fixed cover, rotating cover, transmission mechanism, outer casing and drain basket;

[0007] The rotating cover is rotatably mounted on the fixed cover, and the drain basket is rotatably mounted inside the outer shell. The transmission mechanism is connected to the drain basket. The fixed cover is used to cover the opening of the outer shell. When the fixed cover is covered on the opening of the outer shell, the rotating cover is connected to the transmission mechanism, so that when the rotating cover is driven to rotate, it drives the transmission mechanism to run, and the operation of the transmission mechanism drives the drain basket to rotate.

[0008] The fixed cover is provided with a first limiting structure and a second limiting structure. The rotating cover is installed on the fixed cover from one side of the drain basket. When the rotating cover moves from the drain basket to the fixed cover and abuts against the first limiting structure on the upper side, the lower side of the rotating cover abuts against the second limiting structure. The first limiting structure and the second limiting structure are used to limit the axial displacement of the rotating cover along its rotation axis.

[0009] Beneficial effects: The transmission mechanism is located between the rotating cover and the drain basket, and is used to drive the drain basket to rotate within the outer shell when the rotating cover is driven to rotate. By using a first limiting structure and a second limiting structure respectively abutting the upper and lower sides of the rotating cover on the fixed cover, the axial displacement of the rotating cover can be limited, thereby preventing the rotating cover from swaying or tilting during high-speed rotation, improving the axial stability of the rotating cover, and effectively solving the problem in the prior art where the rotating cover lacks upper restraint, making it prone to swaying or tilting during high-speed rotation.

[0010] In one alternative embodiment, the fixing cover includes a cover body and an abutment structure, the cover body being used to cover the opening of the outer casing;

[0011] The abutting structure and the cover are separate. When the rotating cover moves from the drain basket side to the fixed cover and abuts against the first limiting structure, the abutting structure moves from the drain basket side to the fixed cover until it connects with the cover and forms the second limiting structure.

[0012] Beneficial effects: The fixed cover adopts two separate components: the cover body and the abutment structure. On the one hand, it facilitates the disassembly and assembly of the rotating cover. On the other hand, when the upper side of the rotating cover abuts against the first limiting structure, the abutment structure abuts against the lower side of the rotating cover. The cover body and the abutment structure work together to rotatably limit the rotating cover between the two, thereby limiting the rotating cover from both the top and bottom, preventing the rotating cover from wobbling relative to the cover body when rotating, and improving the stability of the rotating cover during the rotation process.

[0013] In one alternative embodiment, the cover body is provided with a mounting hole for mounting a rotating cover, and a first limiting structure is formed on the inner wall of the mounting hole.

[0014] The rotating cover includes a top plate, side walls surrounding the top plate, and a rotating handle disposed on the top plate;

[0015] When the rotating cover moves from one side of the drain basket toward the mounting hole until the side wall abuts against the first limiting structure, the bottom end of the side wall abuts against the abutting structure, and the top plate passes through the mounting hole so that the rotating handle extends out of the mounting hole, so that the rotating handle can be driven to rotate the rotating cover.

[0016] Beneficial effects: The first limiting structure is set on the inner wall of the mounting hole. The rotating cover includes a top plate and side walls surrounding the outer periphery of the top plate. When the rotating cover moves from below the fixed cover until its side walls abut against the first limiting structure, the bottom end of the side wall can abut against the abutting structure, thereby limiting the axial displacement of the rotating cover from both the top and bottom. Furthermore, the abutment between the side wall and the abutting structure also prevents foreign objects from getting stuck in the gap between the edge of the rotating cover and the mounting hole, or from entering the interior of the rotating cover from the edge of the rotating cover and the mounting hole. In addition, a rotating handle is provided above the top plate, extending from the mounting hole, allowing the user to easily rotate the rotating cover by turning the handle.

[0017] In one alternative embodiment, the inner wall of the mounting hole is inclined toward the center of the mounting hole from the direction away from the drain basket.

[0018] The side wall of the rotating cover is inclined away from the center of the mounting hole in the direction away from the top plate. When the rotating cover moves from the drain basket side to the mounting hole until the side wall abuts against the inner wall of the mounting hole, the inner wall forms a first limiting structure.

[0019] Beneficial effects: The inner wall of the mounting hole is inclined upwards, and the side wall of the rotating cover is inclined downwards. When the rotating cover moves from one side of the drain basket to the mounting hole until the side wall abuts against the inner wall of the mounting hole, the inner wall forms a first limiting structure, eliminating the need for an additional first limiting structure and simplifying the structure.

[0020] In one alternative embodiment, one of the abutting structures and the cover is provided with a buckle, and the other is provided with a slot;

[0021] When the abutting structure moves from one side of the drain basket toward the fixed cover until the buckle and the slot engage, the abutting structure forms a second limiting structure.

[0022] Beneficial effects: The abutment structure and the cover are pre-fixed by snap-fit ​​and slot, which improves assembly efficiency and facilitates disassembly and assembly.

[0023] In one optional embodiment, the cover is provided with a mounting hole, and multiple buckles are provided around the mounting hole on the side of the cover near the drain basket. The abutment structure is annular and is provided with multiple slots around it.

[0024] When the abutting structure moves from the drain basket side toward the fixed cover until the buckle and the slot engage, the hollow area of ​​the annular abutting structure communicates with the mounting hole to facilitate the transmission connection between the rotating cover and the transmission mechanism.

[0025] Beneficial effects: Multiple buckles are arranged around the outer perimeter of the cover around the mounting hole, and multiple slots are correspondingly spaced on the abutment structure. During installation, the abutment structure is installed on the fixed cover from below, and the connection is achieved by the multiple buckles engaging with the multiple slots one by one, resulting in a more reliable and stable fixation. In addition, the abutment structure adopts a ring-shaped design. When the abutment structure is installed under the fixed cover, the hollow area in the middle of the ring-shaped abutment structure can align with the mounting hole, thus avoiding obstruction and facilitating the transmission connection between the rotating cover and the transmission mechanism.

[0026] In one alternative embodiment, the transmission mechanism includes:

[0027] Gear assembly and transmission fitting, the gear assembly includes a driving gear and a driven gear, the driven gear is connected to the transmission fitting, the rotating cover is fixedly connected to the driving gear, and when the fixed cover is placed at the opening of the outer shell, the transmission fitting is circumferentially limited to the drain basket;

[0028] The rotating cover is driven to rotate, which in turn drives the driving gear to rotate. The driving gear then drives the driven gear to rotate, which in turn drives the transmission components to rotate, and the transmission components then drive the drain basket to rotate.

[0029] Beneficial effects: The transmission mechanism uses gear assembly transmission, which is precise, stable and highly reliable. Furthermore, the transmission mating component set between the gear assembly and the drain basket is circumferentially limited and connected to the drain basket. When the rotating cover is driven to rotate and drive the gear assembly to rotate, the transmission mating component can act as an intermediate transmission component to drive the drain basket to rotate. This not only avoids the assembly inconvenience caused by the direct connection between the gear assembly and the drain basket, but also greatly improves the power transmission efficiency between the rotating cover and the drain basket.

[0030] In one alternative implementation, the gear assembly and transmission coupling are mounted on the side of the fixed cover near the drain basket.

[0031] Beneficial effects: The gear assembly and transmission components are installed on the side of the fixed cover near the drain basket. When the fixed cover is closed, the gear assembly and transmission components are hidden inside the fruit and vegetable washing device. Users cannot see the gear assembly and transmission components from the outside, resulting in a better visual appearance.

[0032] In one optional embodiment, the transmission fitting is provided with a first limiting part, and the drain basket is provided with a first fitting part;

[0033] The first limiting part and the first mating part are engaged in the circumferential direction of the drain basket so that the drain basket can rotate synchronously with the transmission mating parts.

[0034] Beneficial effects: The circumferential limiting fit between the first limiting part and the first mating part on the drain basket can prevent relative rotation between the drain basket and the transmission mating parts, ensuring that power is transmitted from the transmission mating parts to the drain basket without loss.

[0035] In one optional embodiment, the driven gear is provided with a second limiting part, and the transmission mating component is provided with a second mating part;

[0036] The second limiting part and the second mating part are engaged in a snap-fit, plug-in, or stop-fit ​​relationship.

[0037] Beneficial effects: By using the second limiting part to engage with the second mating part through snap-fit, plug-fit, or stop engagement, the driven gear and the transmission mating parts are limited in the circumferential direction. This not only enables the driven gear to drive the transmission mating parts to rotate precisely and efficiently, but also facilitates disassembly and assembly.

[0038] In one alternative embodiment, when the gear assembly and transmission mating parts are installed on the side of the fixed cover near the drain basket, the abutment structure of the fixed cover is located on the outer periphery of the driving gear, and the abutment structure is provided with a clearance opening corresponding to the meshing position of the driving gear and the driven gear.

[0039] Beneficial effects: The driving gear is located in the hollow area within the abutment structure, which not only facilitates connection with the rotating cover, but also makes full use of the internal space of the abutment structure, improving the overall compactness of the structure. Furthermore, the avoidance openings on the abutment structure corresponding to the meshing positions of the driving gear and the driven gear facilitate the meshing of the driving gear and the driven gear.

[0040] In one alternative embodiment, the fixing cover is snapped into place with the outer casing.

[0041] Beneficial effects: The fixed cover and the outer shell are fixed by a snap-fit ​​method, which not only makes the fixation reliable and stable, but also makes it easy to open and close.

[0042] In one alternative embodiment, the fixed cover is provided with a drain outlet.

[0043] Beneficial effect: The drain outlet on the fixed cover makes it easy to pour out the drained water after washing. Attached Figure Description

[0078] Furthermore, the technical features involved in the different embodiments of this utility model described below can be combined with each other as long as they do not conflict with each other.

[0079] The following is combined Figures 1 to 17 The following describes embodiments of the present invention.

[0080] According to an embodiment of the present invention, in one aspect, the present invention provides a fruit and vegetable washing device, including: a fixed cover 10, a rotating cover 20, a transmission mechanism 30, an outer shell 40, and a drain basket 50; the rotating cover 20 is rotatably disposed on the fixed cover 10, the drain basket 50 is rotatably disposed inside the outer shell 40, and the transmission mechanism 30 is pulsatorically connected to the drain basket 50; the fixed cover 10 is used to cover the opening of the outer shell 40, and when the fixed cover 10 is covered at the opening of the outer shell 40, the rotating cover 20 is pulsatorically connected to the transmission mechanism 30, so that when the rotating cover 20 is driven to rotate, it drives the transmission mechanism 30 to run, and the running of the transmission mechanism 30 drives the drain basket 50 to rotate. The fixed cover 10 is provided with a first limiting structure 111 and a second limiting structure. The rotating cover 20 is installed on the fixed cover 10 from one side of the drain basket 50. When the rotating cover 20 moves from one side of the drain basket 50 to the fixed cover 10 and abuts against the first limiting structure 111 on the upper side, the lower side of the rotating cover 20 abuts against the second limiting structure. The first limiting structure 111 and the second limiting structure are used to limit the axial displacement of the rotating cover 20 along its rotation axis.

[0081] In the above embodiment, the transmission mechanism 30 is driven between the rotating cover 20 and the drain basket 50, and is used to drive the drain basket 50 to rotate within the outer shell 40 when the rotating cover 20 is driven to rotate. By providing a first limiting structure 111 and a second limiting structure on the fixed cover 10 that respectively abut against the upper and lower sides of the rotating cover 20, the axial displacement of the rotating cover 20 can be limited, thereby preventing the rotating cover 20 from swaying up and down or tilting during high-speed rotation, improving the stability of the axial position of the rotating cover 20, and effectively solving the problem in the prior art where the rotating cover 20 does not have upper restraint and is prone to swaying up and down or tilting during high-speed rotation.

[0082] Specifically, the rotating cover 20 is rotatably connected to the fixed cover 10. The top of the outer casing 40 has an opening, and the fixed cover 10 is closable at this opening. The drain basket 50 is located below the fixed cover 10. The fixed cover 10 can be engaged with the top of the outer casing 40 to prevent the fixed cover 10 from shaking. A first limiting structure 111 is located above the rotating cover 20, and a second limiting structure is located below the rotating cover 20. When the rotating cover 20 is installed on the fixed cover 10, the first limiting structure 111 and the second limiting structure can limit the rotating cover 20 from both the top and bottom, preventing the rotating cover 20 from shaking up and down or tilting. The first limiting structure 111 and the second limiting structure include, but are not limited to, limiting ribs, limiting blocks, and limiting plates. The rotating cover 20 is installed on the fixed cover 10 from the lower side. When the rotating cover 20 moves from the lower side of the fixed cover 10 to the upper side and abuts against the first limiting structure 111, the lower side of the rotating cover 20 abuts against the second limiting structure at the same time, thereby enabling the rotating cover 20 to be limited from both the upper and lower sides.

[0083] In some embodiments, the fixed cover 10 includes a cover body 11 and an abutment structure 12. The cover body 11 is used to cover the opening of the outer shell 40. The abutment structure 12 is separately disposed from the cover body 11. When the rotating cover 20 moves from the drain basket 50 side toward the fixed cover 10 to the upper side and abuts against the first limiting structure 111, the abutment structure 12 moves from the drain basket 50 side toward the fixed cover 10 until it connects with the cover body 11 and forms a second limiting structure.

[0084] In the above embodiment, the fixed cover 10 adopts two separate components: the cover body 11 and the abutment structure 12. On the one hand, it facilitates the disassembly and assembly of the rotating cover 20. On the other hand, when the upper side of the rotating cover 20 abuts against the first limiting structure 111, the abutment structure 12 abuts against the lower side of the rotating cover 20. The cover body 11 and the abutment structure 12 cooperate to rotatably limit the rotating cover 20 between the two, thereby limiting the rotating cover 20 from both the upper and lower sides, preventing the rotating cover 20 from swaying up and down relative to the cover body 11 when rotating, and improving the stability of the rotating cover 20 during the rotation process.

[0085] In some embodiments, combined with Figures 2 to 5 , Figures 9 to 11 As shown, the cover 11 is provided with a mounting hole 100 for mounting the rotating cover 20, and a first limiting structure 111 is formed on the inner wall of the mounting hole 100. The rotating cover 20 includes a top plate 21, a side wall 22 surrounding the top plate 21, and a rotating handle 23 disposed on the top plate 21. When the rotating cover 20 moves from the drain basket 50 to the mounting hole 100 until the side wall 22 abuts against the first limiting structure 111, the bottom end of the side wall 22 abuts against the abutting structure 12, and the top plate 21 passes through the mounting hole 100 so that the rotating handle 23 extends out of the mounting hole 100 so that the rotating handle 23 can be driven to rotate the rotating cover 20.

[0086] In the above embodiment, the first limiting structure 111 is disposed on the inner wall of the mounting hole 100. The rotating cover 20 includes a top plate 21 and a side wall 22 disposed around the outer periphery of the top plate 21. When the rotating cover 20 moves from below the fixed cover 10 until its side wall 22 abuts against the first limiting structure 111, the bottom end of the side wall 22 can abut against the abutting structure 12, thereby restricting the axial displacement of the rotating cover 20 from both the top and bottom. Furthermore, the abutting between the side wall 22 and the abutting structure 12 can also prevent foreign objects from getting stuck in the gap between the edge of the rotating cover 20 and the mounting hole 100, or from entering the interior of the rotating cover 20 from the edge of the rotating cover 20 and the mounting hole 100. In addition, a rotating handle 23 disposed above the top plate 21 can extend out of the mounting hole 100, making it convenient for the user to turn the rotating handle 23 to drive the rotating cover 20 to rotate.

[0087] Specifically, the first limiting structure 111 is a limiting flange surrounding the inner circumference of the mounting hole 100. The top plate 21 is horizontally positioned, and the outer circumference of the top plate 21 is provided with an annular sidewall 22 extending downward at an incline. When the rotating cover 20 is installed to the position where the annular sidewall 22 abuts and engages with the lower part of the limiting flange, the lower end face of the annular sidewall 22 is supported and limited on the abutting structure 12, and the upper end face of the abutting structure 12 constitutes the second limiting structure.

[0088] Furthermore, the first limiting structure 111 is an annular limiting flange that extends upward along the inner periphery of the mounting hole 100. The outer periphery of the top plate 21 of the rotating cover 20 is provided with an annular abutting flange that extends downward. The outer diameter of the annular abutting flange is smaller than the inner diameter of the annular limiting flange, and the outer wall surface of the abutting flange is in close contact with the bottom surface of the limiting flange. This reduces the gap between the edge of the rotating cover 20 and the mounting hole 100 of the cover body 11, preventing foreign objects from entering the interior of the rotating cover 20.

[0089] Furthermore, the rotating handle 23 is a pressed structure formed by the top plate 21 protruding upwards. When the rotating cover 20 is assembled into the mounting hole 100 from below the fixed cover 10, and the annular sidewall 22 of the outer periphery of the rotating cover 20 abuts against the first limiting structure 111 in the mounting hole 100, the rotating handle 23 can extend out of the mounting hole 100.

[0090] In some embodiments, combined with Figures 2 to 5 , Figure 10 and Figure 11As shown, the inner wall of the mounting hole 100 is inclined in a direction away from the drain basket 50 and towards the center of the mounting hole 100; the side wall 22 of the rotating cover 20 is inclined in a direction away from the top plate 21 and away from the center of the mounting hole 100. When the rotating cover 20 moves from the drain basket 50 to the mounting hole 100 until the side wall 22 abuts against the inner wall of the mounting hole 100, the inner wall forms a first limiting structure 111.

[0091] In the above embodiment, the inner wall of the mounting hole 100 is inclined upward, and the side wall 22 of the rotating cover 20 is inclined downward. When the rotating cover 20 moves from the drain basket 50 to the mounting hole 100 until the side wall 22 abuts against the inner wall of the mounting hole 100, the inner wall forms a first limiting structure 111. There is no need to set the first limiting structure 111 separately, which simplifies the structure.

[0092] In some optional embodiments, the inner peripheral wall of the mounting hole 100 is frustoconical, and the rotating cover 20 includes a top plate 21. The outer peripheral wall of the top plate 21 is frustoconical. The inner peripheral diameter of the mounting hole 100 gradually decreases along the insertion direction of the rotating cover 20, and the outer diameter of the top plate 21 also gradually decreases. The inner peripheral wall of the frustoconical mounting hole 100 constitutes a first limiting structure 111, and the frustoconical outer peripheral wall of the top plate 21 constitutes a second limiting structure. By setting the inner peripheral wall of the frustoconical mounting hole 100 and the frustoconical outer peripheral wall of the top plate 21 to be frustoconical, the limiting of the two can be achieved without the need to add an additional limiting structure. Furthermore, the inner peripheral wall of the frustoconical mounting hole 100 and the frustoconical outer peripheral wall of the top plate 21 can also play a guiding role, improving the assembly efficiency of the rotating cover 20.

[0093] In other embodiments, the first limiting structure 111 is a protruding edge extending circumferentially from the top of the mounting hole 100 to the center of the mounting hole 100. When the rotating cover 20 moves from the drain basket 50 side toward the mounting hole 100 until the top of the rotating cover 20 abuts against the bottom of the protruding edge, the bottom end of the side wall 22 of the rotating cover 20 abuts against the abutting structure 12, thereby restricting the axial displacement of the rotating cover 20 on both the upper and lower sides.

[0094] In the above embodiments, the first limiting structure 111 is set as a convex edge extending circumferentially from the top of the mounting hole 100 to the center of the mounting hole 100. This structure is simple and low in cost.

[0095] In some embodiments, one of the abutment structure 12 and the cover 11 is provided with a buckle 112 and the other is provided with a slot 121; when the abutment structure 12 moves from the drain basket 50 side toward the fixed cover 10 until the buckle 112 and the slot 121 engage, the abutment structure 12 forms a second limiting structure.

[0096] In the above embodiments, the abutment structure 12 and the cover 11 are pre-fixed by snap-fit ​​112 and slot 121, which improves assembly efficiency and facilitates disassembly and assembly.

[0097] Furthermore, combined Figure 5 , Figure 7 , Figure 8 , Figure 10 As shown, bolt posts are also provided on the abutment structure 12 and the cover 11 respectively. The abutment structure 12 and the cover 11 are pre-fixed by the buckle 112 and the slot 121 and then finally fixed by bolts, resulting in higher structural stability.

[0098] In some embodiments, the cover 11 is provided with a mounting hole 100, and a plurality of buckles 112 are provided around the mounting hole 100 on the side of the cover 11 near the drain basket 50. The abutment structure 12 is annular and is provided with a plurality of slots 121. When the abutment structure 12 moves from the drain basket 50 side toward the fixed cover 10 until the buckle 112 engages with the slot 121, the hollow area of ​​the annular abutment structure 12 communicates with the mounting hole 100 so as to facilitate the transmission connection between the rotating cover 20 and the transmission mechanism 30.

[0099] In the above embodiment, multiple buckles 112 are arranged around the cover 11 surrounding the mounting hole 100, and multiple slots 121 are correspondingly spaced on the abutment structure 12. During installation, the abutment structure 12 is installed on the fixed cover 10 from the bottom, and the connection is achieved by the multiple buckles 112 and the multiple slots 121 engaging one-to-one, making the fixation more reliable and stable. In addition, the abutment structure 12 adopts a ring-shaped design. When the abutment structure 12 is installed below the fixed cover 10, the hollow area in the middle of the ring-shaped abutment structure 12 can connect with the mounting hole 100, which plays a role in avoiding interference and facilitating the transmission connection between the rotating cover 20 and the transmission mechanism 30.

[0100] Specifically, the abutment structure 12 has an annular body with an opening on one side. The shape of the annular body matches the shape of the annular abutment flange of the rotating cover 20. The outer diameter of the annular abutment flange is larger than the inner diameter of the annular body but smaller than the outer diameter of the annular body, thereby ensuring that the annular abutment flange on the outer periphery of the rotating cover 20 can support and abut against the annular body of the abutment structure 12. During installation, the rotating cover 20 is installed from the bottom of the cover body 11 upwards, with the side wall 22 abutting against the first limiting structure 111 of the cover body 11, and the bottom of the rotating cover 20 overlapping the upper side of the abutment structure 12. In addition, the opening of the annular body facilitates the connection between the transmission mechanism 30 and the drain basket 50.

[0101] In some embodiments, combined with Figure 2 , Figure 3 , such as 7, Figure 14 and Figure 15As shown, the transmission mechanism 30 includes a gear assembly and a transmission fitting component 33. The gear assembly includes a driving gear 31 and a driven gear 32. The driven gear 32 is connected to the transmission fitting component 33. The rotating cover 20 is fixedly connected to the driving gear 31. When the fixed cover 10 is placed over the opening of the outer casing 40, the transmission fitting component 33 is circumferentially limited and connected to the drain basket 50. The rotating cover 20 is driven to rotate, which in turn drives the driving gear 31 to rotate. The rotation of the driving gear 31 drives the driven gear 32 to rotate, which in turn drives the transmission fitting component 33 to rotate, and the rotation of the transmission fitting component 33 drives the drain basket 50 to rotate.

[0102] In the above embodiments, the transmission mechanism 30 uses a gear assembly for transmission, which is precise, stable and reliable. Furthermore, the transmission fitting 33 is provided between the gear assembly and the drain basket 50. The transmission fitting 33 is circumferentially limited to the drain basket 50. When the rotating cover 20 is driven to rotate and drive the gear assembly to rotate, the transmission fitting 33 can act as an intermediate transmission component to drive the drain basket 50 to rotate. This not only avoids the assembly inconvenience caused by the direct connection between the gear assembly and the drain basket 50, but also greatly improves the power transmission efficiency between the rotating cover 20 and the drain basket 50.

[0103] Specifically, the transmission fitting 33 is in upper limit engagement with the drain basket 50 in the circumferential direction. The output end of the driven gear 32 is in limit engagement with the transmission fitting 33, and can drive the transmission fitting 33 to rotate when the rotating cover 20 is driven to rotate, thereby driving the drain basket 50 to rotate. The driving gear 31 is fixedly connected to the rotating cover 20; the driven gear 32 meshes with the driving gear 31 for transmission. The driven gear 32 and the transmission fitting 33 are rotatably mounted below the fixed cover 10, and the transmission fitting 33 and the driven gear 32 are in upper limit engagement in the circumferential direction, so as to realize that the driven gear 32 drives the transmission fitting 33 to rotate.

[0104] In some other embodiments, the transmission mechanism 30 may include a chain drive mechanism and a transmission coupling component 33. The transmission coupling component 33 includes a chain, a large sprocket connected to the rotating cover 20, and a small sprocket connected to the transmission coupling component 33. By rotating the rotating cover 20, the large sprocket is driven to rotate, and the large sprocket drives the small sprocket through the chain, thereby driving the transmission coupling component 33 to rotate, thus realizing the rotation of the drain basket 50.

[0105] In the above embodiments, the transmission mechanism 30 is composed of a chain drive mechanism and a transmission mating part 33, which makes the rotation operation reliable and efficient.

[0106] In some embodiments, the gear assembly and transmission mating member 33 are mounted on the side of the fixed cover 10 near the drain basket 50.

[0107] In the above embodiment, the gear assembly and the transmission coupling 33 are both installed on the side of the fixed cover 10 near the drain basket 50. When the fixed cover 10 is closed, the gear assembly and the transmission coupling 33 are hidden inside the fruit and vegetable washing device. Users cannot see the gear assembly and the transmission coupling 33 from the outside, resulting in a better visual effect.

[0108] In some embodiments, the transmission fitting 33 is provided with a first limiting part 331, and the drain basket 50 is provided with a first fitting part 51; the first limiting part 331 and the first fitting part 51 are engaged in a circumferential upper limit fit of the drain basket 50 so that the drain basket 50 can rotate synchronously with the transmission fitting 33.

[0109] In the above embodiment, the first limiting part 331 and the first mating part 51 are circumferentially limited and mated in the drain basket 50 to prevent relative rotation between the drain basket 50 and the transmission mating part 33, and to ensure that the power is transmitted from the transmission mating part to the drain basket 50 without loss.

[0110] In some embodiments, combined with Figures 14 to 16 As shown, the drain basket 50 includes a plurality of longitudinal ribs 52 spaced apart along the circumference. The first mating part 51 includes a limiting groove formed by the gap between two adjacent longitudinal ribs 52. The first limiting part 331 includes a stop rib provided on the transmission mating member 33. The stop rib extends into the limiting groove and can abut against the longitudinal ribs 52 when the transmission mating member 33 rotates, thereby driving the drain basket 50 to rotate.

[0111] Preferably, there are multiple stop ribs, and the multiple stop ribs are evenly spaced along the circumference of the transmission fitting 33; the transmission fitting 33 is located at the basket opening of the drain basket 50, and the stop ribs are fixedly located below the transmission fitting 33. When the fixed cover 10 is closed, the stop ribs can slide into the limiting groove along the edge of the basket opening and be limited in the limiting groove in the circumferential direction.

[0112] Furthermore, the transmission fitting component 33 includes an annular fitting plate, a central connecting portion, and several ribs. The outer circumferential shape and dimensions of the annular fitting plate match the shape and dimensions of the basket opening of the drain basket 50. Multiple stop ribs are spaced apart on the bottom wall of the annular plate. The central connecting portion is located at the center of the annular fitting plate and is rotatably connected to the fixed cover 10, and has a limiting engagement with the driven gear 32. Several ribs connect the connecting portion and the annular body, and are arranged at intervals along the outer circumference of the connecting portion. The stop ribs at the bottom of the transmission fitting component 33 engage with the gaps between the adjacent longitudinal ribs 52 of the drain basket 50, thereby enabling the transmission fitting component 33 to drive the drain basket 50 to rotate.

[0113] In this embodiment, the stop rib can be non-interlocking with the longitudinal ribs 52 of the drain basket 50, as long as the stop rib is positioned in the gap between two connected longitudinal ribs 52, it can drive the drain basket 50 to rotate. Alternatively, the stop rib can be interlocked with the longitudinal ribs 52 of the drain basket 50. After the rotating cover 20 rotates, it drives the driving gear 31 and the driven gear 32 to rotate, which in turn drives the transmission mating part 33 to rotate, and then drives the drain basket 50 to rotate.

[0114] In some embodiments, the driven gear 32 is provided with a second limiting part 321, and the transmission mating member 33 is provided with a second mating part 332; the second limiting part 321 and the second mating part 332 are engaged in a snap-fit, or inserted in a plug-in, or stopped engagement.

[0115] In the above embodiments, the driven gear 32 and the transmission fitting 33 are limited in the circumferential direction by means of snap-fit, plug-fit, or stop-fit ​​between the second limiting part 321 and the second mating part 332. This not only enables the driven gear 32 to drive the transmission fitting 33 to rotate precisely and efficiently, but also facilitates disassembly and assembly.

[0116] Specifically, in combination Figure 14 and Figure 17 As shown, the transmission mating part 33 is located below the driven gear 32, the second limiting part 321 is located below the driven gear 32, and the second mating part 332 is located above the second limiting part 321. The second limiting part 321 and the second mating part 332 are respectively a rib and a slot. The second limiting part 321 and the second mating part 332 achieve limiting by plugging and mating.

[0117] Preferably, the second limiting part 321 is a rib, and the second mating part 332 is a slot. The second limiting part 321 includes a plurality of ribs spaced apart along the circumference of the driven gear 32, and the second mating part 332 includes a plurality of slots spaced apart along the circumference of the driven gear 32. The plurality of ribs are inserted into and limited in the plurality of slots in a one-to-one correspondence. The cooperation of the plurality of ribs and the plurality of slots can further improve the stability and reliability of the transmission between the driven gear 32 and the transmission mating part 33.

[0118] Furthermore, an annular stepped groove is provided below the driven gear 32, and multiple ribs are provided at intervals along the circumference of the annular stepped groove. An annular boss is provided at the center of the transmission mating part 33, and multiple openings are provided at intervals on the annular boss to form multiple insertion slots. When the transmission mating part 33 is installed on the fixed cover 10, the annular boss extends into and is positioned in the annular stepped groove, and the multiple ribs in the annular stepped groove are inserted into the multiple insertion slots on the annular boss, thereby realizing the limited connection between the driven gear 32 and the transmission mating part 33 in the circumferential direction.

[0119] In some embodiments, the driving gear 31 is fixedly connected to the rotating cover 20 below the rotating cover 20 by a first fastener 60. The transmission engagement member 33 is located below the driven gear 32; the transmission engagement member 33 and the driven gear 32 are rotatably connected to the fixed cover 10 below by a second fastener 70.

[0120] Specifically, a first connecting shaft is fixedly installed at the center of the bottom wall of the fixed cover 10, and the driven gear 32 is rotatably sleeved on the first connecting shaft. The center of the transmission fitting 33 is provided with a connecting hole, and the second fastener 70 passes through the connecting hole and is fixedly connected to the first connecting shaft. The driven gear 32 is sleeved on the outside of the first connecting shaft and can rotate. The transmission fitting 33 is installed on the lower side of the driven gear 32 for axial positioning of the driven gear 32. The upper side of the transmission fitting 33 is provided with an insertion groove, and the driven gear 32 is provided with a rib. The two are engaged to realize that the driven gear 32 drives the transmission fitting 33 to rotate. The driving gear 31 meshes with the driven gear 32. A second connecting shaft is provided at the middle of the bottom wall of the rotating cover 20. The driving gear 31 is rotatably sleeved on the second connecting shaft. The first fastener 60 is threaded or snapped fixed on the second connecting shaft. The driving gear 31 is limited between the rotating cover 20 and the first fastener 60. The rotating cover 20 and the first fastener 60 realize the axial limitation of the driving gear 31.

[0121] In some embodiments, when the gear assembly and transmission mating member 33 are installed on the side of the fixed cover 10 near the drain basket 50, the abutment structure 12 of the fixed cover 10 is located on the outer peripheral side of the driving gear 31, and the abutment structure 12 is provided with a clearance opening corresponding to the meshing position of the driving gear 31 and the driven gear 32.

[0122] In the above embodiment, the driving gear 31 is located in the hollow area within the abutment structure 12, which not only facilitates connection with the rotating cover 20, but also makes full use of the internal space of the abutment structure 12, improving the compactness of the overall structure. Furthermore, the avoidance openings provided on the abutment structure 12 corresponding to the meshing positions of the driving gear 31 and the driven gear 32 facilitate the meshing of the driving gear 31 and the driven gear 32.

[0123] In some embodiments, the fixing cover 10 is snapped together with the outer casing 40.

[0124] In the above embodiments, the fixed cover 10 and the outer shell 40 are fixed by a snap-fit ​​method, which not only ensures a secure and stable fixation but also facilitates opening and closing.

[0125] Specifically, the inner circumference of the opening of the outer shell 40 is provided with a snap-fit ​​rib, and the outer circumference of the fixing cover 10 is provided with a corresponding snap-fit ​​groove. The fixing cover 10 and the outer shell 40 are fixed together by the snap-fit ​​rib and the snap-fit ​​groove. The bottom center of the outer shell 40 is provided with a protruding rotating support, and the drain basket 50 is provided with a rotating mating part at the corresponding position to realize the rotation of the drain basket 50 relative to the outer shell 40.

[0126] In some embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, the fixed cover 10 is provided with a drain outlet 110.

[0127] In the above embodiment, the drain outlet 110 provided on the fixed cover 10 facilitates the pouring out of the drained water after washing.

[0128] In this embodiment, the rotating cover 20 abuts against the cover body 11 from below. A drive gear 31 is mounted on the lower middle side of the rotating cover 20 via a first fastener 60. The top plate 21 of the rotating cover 20 is circular, and the side wall 22 is frustoconical, engaging with the inclined annular limiting flange at the mounting hole 100 on the cover body 11. The bottom surface of the side wall 22 of the rotating cover 20 overlaps with the abutment structure 12. This design prevents the rotating cover 20 from wobbling relative to the cover body 11 during rotation and reduces the gap between the edge of the rotating cover 20 and the cover body 11, preventing foreign objects from entering the interior of the rotating cover 20. Alternatively, in other alternative embodiments, the rotating cover 20 has a limiting part, and the cover body 11 has a mating part, which abut against each other to achieve the aforementioned inclined surface abutment effect. The limiting part can be a rib on the periphery of the rotating cover 20, and the mating part can be a groove in the cover body 11, with the rib engaging within the groove to achieve limiting.

[0129] In some embodiments, the drain basket 50 has a rotating groove at its bottom center and the interior of the outer shell 40, and the other has a rotating column. The rotating column can cooperate with the rotating groove to enable the drain basket 50 to rotate relative to the outer shell 40.

[0130] Although embodiments of the present invention have been described in conjunction with the accompanying drawings, those skilled in the art can make various modifications and variations without departing from the spirit and scope of the present invention, and such modifications and variations all fall within the protection scope of the embodiments of this application.
