Description

Technical Field

[0001] This utility model belongs to the technical field of daily cleaning devices, and in particular relates to a drain basket. Background Technology

[0002] Drain baskets are commonly used daily cleaning devices. Traditional draining methods rely on manual shaking or long periods of stillness, which are inefficient and laborious. A Chinese utility model patent with application number CN202420221480.3 discloses an eccentric pressing drain basket, including: a drain basket shell with a pressing shell slidably provided on the outside, a positioning sleeve provided inside the pressing shell, a pressing spring provided inside the positioning sleeve, and a gear groove provided on the side of the positioning sleeve near the drain basket shell; a filter basket, located inside the drain basket shell, with a transmission disc on the top of the filter basket, and a first bevel gear fixed on the top of the transmission disc; a pressing rod, located inside the pressing spring; and a quarter gear, matched and connected to the gear groove. Although this solution simplifies the operation process, it still has significant drawbacks: (1) the intermittent transmission of the quarter gear requires multiple presses to accumulate sufficient speed, resulting in high user operation frequency, complex bevel gear transmission structure, long force transmission path, and the inability to fully convert pressing kinetic energy into rotational kinetic energy. (2) Traditional transmission mechanisms are prone to causing the basket to rotate in the opposite direction when resetting, which not only cancels the centrifugal dehydration effect, but also causes the food to swirl and absorb water, reducing the dehydration efficiency. The inertial impact generated by the reversal may cause the components to loosen or the structure to be damaged. Utility Model Content

[0042] The beneficial effects of this utility model are:

[0043] 1. By setting up a speed-increasing gear mechanism, the linear motion of the rack is accelerated through input and output gears, transforming a single pressing stroke into multiple high-speed rotations of the basket. Compared to traditional dehydration tools, users only need to operate with smaller amplitude and lower frequency, significantly increasing the basket speed, enhancing the centrifugal force effect, and making draining faster and more efficient.

[0044] Specifically, the double gears work in conjunction with the output gear to achieve two-stage speed change, converting the short-stroke linear input of the rack into the high-speed rotational output of the output gear.

[0045] Second, by setting up an internal meshing ratchet mechanism, when the rack drives the dial to rotate in the forward direction, the pawl engages with the ratchet teeth to push the ratchet and drive the basket to rotate; when the dial rotates in the reverse direction, the pawl slides over the ratchet teeth, and the ratchet and dial transmission are separated, ensuring that the basket accelerates continuously in only one direction, and the centrifugal force is superimposed in a directional manner to form a continuous centrifugal force field, avoiding secondary water absorption of the food caused by reverse rotation, which significantly improves the dehydration effect, especially for leafy vegetables (such as lettuce and spinach).

[0046] Furthermore, the anti-reverse design prevents torsional vibration of the driven shaft caused by sudden reverse rotation of the basket during a sudden stop, reducing the risk of loosening of connecting parts. During the reset phase, there is no transmission load from the original motion state of the basket; the reset assembly only needs to overcome the frictional resistance of the rack and pinion mechanism.

[0056] To make the objectives, technical solutions, and advantages of this utility model clearer, the present utility model will be described in detail below with reference to the accompanying drawings and specific embodiments.

[0057] It should also be noted that, in order to avoid obscuring the present invention with unnecessary details, only the structures and / or processing steps closely related to the present invention are shown in the accompanying drawings, while other details that are not closely related to the present invention are omitted.

[0058] Additionally, it should be noted that the terms “comprising,” “including,” or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such process, method, article, or apparatus.

[0059] like Figure 1-8A drain basket includes a box body 1, a basket body 2, a drive assembly, a transmission assembly, and a reset assembly. The box body 1 includes a box body 11 and a box base 12 adapted to support the box body 11. The box body 11 includes an open main cavity 111 for holding contents to be stirred. The box base 12 forms a secondary cavity 121, within which a limiting cover 122 is provided. The limiting cover 122 and the box base 12 enclose a transmission cavity 123, and the transmission assembly is disposed in the transmission cavity 123. The basket body 2 is disposed in the main cavity 111. The basket body 2 includes a basket bottom 21 and a basket perimeter 22, with some drain holes 23 evenly distributed on the basket bottom 21. The basket perimeter 22 includes a drain area 221 and a non-drain area 222 arranged sequentially from bottom to top, with the remaining drain holes 23 distributed in the drain area 221. The drive assembly includes a grip 31, a pressing handle 32, and a transmission bar 33. The grip 31 is mounted on the housing 11. One end of the pressing handle 32 is pivotally connected to the grip 31, and the other end is pivotally connected to the transmission bar 33. The transmission bar 33 includes a rack 331 and is telescopically movable relative to the transmission cavity 123. The transmission assembly includes a speed-increasing gear mechanism and an internal meshing ratchet mechanism 42. The speed-increasing gear mechanism includes a double gear 411 and an output gear 413. The double gear 411 includes a first gear 4112 and a second gear 4113 coaxially fastened to the drive shaft 4111. The first gear 4112 is adapted to form the input gear 412, and the second gear 4113 directly meshes with the output gear 413. The angular velocity of the output gear 413 is configured to be greater than the angular velocity of the input gear 412 to achieve speed-increasing transmission. The input gear 412 meshes with the rack 331, converting the linear motion of the rack 331 into rotational motion. The internal meshing ratchet mechanism 42 includes a dial 421, pawls 422, and a ratchet 423. An output gear 413 is coaxially fixed to the dial 421. Two symmetrically distributed pawls 422 are pivotally connected to the dial 421. The inner circumferential wall of the ratchet 423 is provided with ratchet teeth 4231. The ratchet 423 is fastened to a driven shaft 424, and the dial 421 is loosely fitted onto the driven shaft 424. One end of the driven shaft 424 extends into the main cavity 111 and connects to the basket 2, which is adapted to rotate under the drive of the driven shaft 424. The reset assembly is configured to drive the drive assembly to reset after operation, preparing for the next operation. The reset assembly includes a spring plate 51, which includes a first spring plate 511 and a second spring plate 512 adapted to form a V-shaped structure. The first spring plate 511 is connected to the pressing handle 32, and the second spring plate 512 abuts against the grip handle 31.

[0060] The working principle of this utility model is as follows:

[0061] The user presses the handle 32, which drives the transmission bar 33. The rack 331 on the transmission bar 33 meshes with the input gear 412 of the speed-increasing gear mechanism, converting the user's pressing action into the rotational power of the output gear 413. The output gear 413 is coaxially fixed to the dial 421, so the dial 421 also rotates at a high angular velocity. When the rack 331 pushes the dial 421 to rotate forward, the pawl 422 engages with the ratchet 4231 to drive the ratchet 423, which in turn drives the driven shaft 424 to rotate. Driven by the driven shaft 424, the basket 2 rotates at high speed. Utilizing the principle of centrifugal force, the surface water of the fruits and vegetables placed in the basket 2 is thrown out through the drainage holes 23 (drainage areas 221 of the basket bottom 21 and basket perimeter 22) distributed on the basket 2 under the action of centrifugal force, achieving rapid drainage. At the same time, the design of the non-drainage area 222 of the basket 2 reduces excessive water splashing, and the cover further prevents water from being thrown out of the self-draining cavity 111, keeping the usage environment clean. The reset component provides a linear reset force, driving the rack 331 to reset and causing the dial 421 to rotate in the opposite direction. The pawl 422 radially disengages from the ratchet 4231 and slides over the back of the ratchet 4231. The ratchet 423 enters a free state, which can be stationary or maintained in its original direction of rotation by inertia under the drive of the basket 2. The user repeats the press-release action until the food dehydration is complete. Each press adds a unidirectional acceleration of the basket 2, and the centrifugal force continues to accumulate.

[0062] In this embodiment, a connector 4241 is provided at the end of the driven shaft 424, and a connecting groove 211 is formed in the center of the bottom of the basket 2. The connector 4241 is a hexagonal prism with a non-circular cross-section. The connecting groove 211 and the connector 4241 are detachably fitted together along the axial direction of the driven shaft 424 to transmit torque. The basket 2 and the driven shaft 424 form a circumferential limit. The fitting relationship between the basket 2 and the driven shaft 424 can be at least partially self-locked by gravity in the axial direction. The basket 2 can be separated by lifting it, which is convenient for disassembling and washing the basket 2. The fitting relationship between the basket 2 and the driven shaft 424 transmits torque in the circumferential direction through a surface connection without relative rotation.

[0063] In some other embodiments, the drain basket includes a cover over the box body 1, the cover being adapted to prevent water from being thrown out of the autonomous cavity 111, keeping the surrounding environment dry and clean, avoiding water splashing and causing inconvenience, and improving the safety and comfort of product use.

The limiting cover 122 includes a plurality of limiting posts 1223. The limiting posts 1223 are adapted to abut against the limiting ratchet 423 along the extension direction of the driven shaft 424. The limiting posts 1223 axially preload the ratchet 423 to eliminate or limit axial movement and prevent the pawl 422 from disengaging under high-speed conditions.

The second guide rail 3121 can slide with the second guide groove 3321 and the third guide groove 3221.

[0068] In this embodiment, the rack 331 includes a starting end and a ending end adapted to connect to the rack head 332.
