[0002] Currently, there is a drain basket (also called a "dehydrator") for washing fruits and vegetables on the market. It uses the rotation of a mesh basket in a bowl-shaped container and the rotating centrifugal force of the fruits and vegetables in the mesh basket to achieve rapid dehydration. The dehydration speed is much higher than natural draining, so it is loved by many consumers, especially when making foods such as vegetable salads, the washed vegetables can be quickly dehydrated and drained, saving time and effort.

[0003] Existing drain baskets can be divided into hand-pull drain baskets, hand-cranked drain baskets, push-type drain baskets and electric drain baskets according to the driving method. The driving part drives the net basket to rotate in the external container. The rotation of the net basket is generally unidirectional. After the driving part stops, the net basket can continue to rotate under the action of inertia to avoid damage to the driving part. The unidirectional rotation of the net basket of the existing drain basket is usually achieved by an overrunning clutch, and the self-clutching function of the overrunning clutch is used to achieve the unidirectional drive of the net basket. However, this clutch structure is relatively complex, and requires interference fit inside and outside, which is inconvenient to assemble and has high production costs. Summary of the invention

DETAILED DESCRIPTION

[0053] In order to further understand the content of the utility model, the utility model is described in detail in conjunction with the drawings and embodiments.

[0054] [Example 1]

[0055] Combination Figures 1 to 7As shown, a clutch transmission mechanism of a drain basket in this embodiment includes a first transmission member 1 located at a driving end and a second transmission member 2 located at a rotary dehydration end. The second transmission member 2 has a central hole 2-1 for the first transmission member 1 to be inserted. The driving end can be a manual driving device, such as an existing hand-pull driving structure, a hand-cranked driving structure, and a press-driving structure, or an electric driving device. The driving end drives the first transmission member 1 to rotate. The first transmission member 1 and the second transmission member 2 are transmitted through a clutch structure, thereby driving the rotary dehydration end to rotate. The rotary dehydration end can be a mesh basket or a dehydration basket of a drain basket. A plurality of oblique convex ribs 1-1 are distributed on the periphery of the first transmission member 1. The oblique convex ribs 1-1 are provided with a first occlusal surface 1a and a first disengagement surface 1b. In this embodiment, the oblique convex ribs 1-1 are preferably evenly distributed in three, and the three oblique convex ribs 1-1 are inclined along the same rotation direction. A plurality of clutch tongues 3 are provided on the outer periphery of the center hole 2-1 on the second transmission member 2. An elastic member 4 is provided on the rear side of the clutch tongue 3 to keep the clutch tongue 3 elastically extending into the center hole 2-1. A second occlusal surface 3a and a second disengagement surface 3b are provided on one end of the clutch tongue 3 facing the center hole 2-1. The second occlusal surface 3a and the second disengagement surface 3b extend into the center hole 2-1 and can be extended and retracted in the radial direction or nearly in the radial direction. The elastic member 4 preferably adopts a compression spring. A limiting groove or limiting column for fixing the compression spring can be provided on the rear side of the clutch tongue 3. In this embodiment, the clutch tongue 3 is also preferably evenly distributed in three groups on the second transmission member 2, and the clutch tongue 3 and the oblique convex rib 1-1 are exactly matched one by one.

[0056] The first engaging surface 1a on the first transmission member 1 engages with the second engaging surface 3a of the corresponding clutch tongue 3 along the rotational driving direction to drive the second transmission member 2 to rotate; when the first transmission member 1 and the second transmission member 2 generate relative rotational motion, the first disengaging surface 1b on the first transmission member 1 contacts with the second disengaging surface 3b of the corresponding clutch tongue 3 and generates a thrust in the opposite direction of the elastic force of the elastic member 4 to disengage the oblique convex rib 1-1 from the clutch tongue 3. The clutch principle between the first transmission member 1 and the second transmission member 2 can be referred to Figures 5 to 7 As shown: Figure 5 The figure shows the engagement transmission state of the first transmission member 1 and the second transmission member 2. The first transmission member 1 is the active member. Figure 5 The first engaging surface 1a on the inclined convex rib 1-1 and the second engaging surface 3a of the clutch hanging tongue 3 are engaged with each other, and the rotational torque and speed of the first transmission member 1 are transmitted to the driven second transmission member 2 through the clutch hanging tongue 3, driving the second transmission member 2 to rotate synchronously along the clutch hanging tongue 3. Figure 5 Rotate counterclockwise in the direction of the arrow. Figure 6 and Figure 7The figure shows the separation state of the first transmission member 1 and the second transmission member 2. When the first transmission member 1 slows down, stops or rotates in the reverse direction, the second transmission member 2 continues to rotate counterclockwise due to inertia. At this time, the first transmission member 1 and the second transmission member 2 produce a relative differential rotational motion, so that the first disengagement surface 1b on the inclined convex rib 1-1 contacts the second disengagement surface 3b of the clutch tongue 3 (as shown in FIG. Figure 6 As shown), since the first disengagement surface 1b and the second disengagement surface 3b are constructed to generate a force component in the opposite direction to the elastic force of the elastic member 4, the first disengagement surface 1b has an outward thrust on the clutch tongue 3 (as shown in FIG. Figure 7 ), and the thrust is greater than the elastic force of the elastic member 4, forcing the clutch tongue 3 to shrink outward from the center hole 2-1, thereby preventing the torque from being transmitted between the two and achieving power separation. It can be understood that the above-mentioned "relative differential rotational motion" refers to the relative motion between the first transmission member 1 and the second transmission member 2, which is different from the synchronous rotational motion of the first transmission member 1 and the second transmission member 2 (at this time, the first transmission member 1 and the second transmission member 2 are relatively stationary), and can be summarized into three situations: 1) When the first transmission member 1 loses driving force, the first transmission member 1 decelerates rapidly while the second transmission member 2 still rotates rapidly under the action of inertia. At this time, relative rotational motion is generated between the first transmission member 1 and the second transmission member 2 due to the speed difference; 2) When the first transmission member 1 loses driving force and stops rotating (the speed is zero), and the second transmission member 2 will still rotate for a period of time under the action of inertia. At this time, relative rotational motion is also generated between the first transmission member 1 and the second transmission member 2; 3) When the first transmission member 1 generates a driving force in the opposite direction (such as when the drive device is reset by hand pulling or pressing), the first transmission member 1 and the second transmission member 2 rotate in opposite directions (equivalent to the speed of the first transmission member 1 being a negative value), and relative rotational motion is also generated between the two. That is, in the unidirectional rotation working scenario of the drain basket, the first transmission member 1 (active member) generates a differential due to the disappearance or reversal of the driving force and the second transmission member 2 (driven member) that continues to rotate due to inertia, thereby generating a relative differential rotational motion. When the first transmission member 1 and the second transmission member 2 generate a relative differential rotational motion, the first transmission member 1 and the second transmission member 2 can be disengaged with the help of the clutch transmission mechanism, so that the first transmission member 1 will not hinder the continued rotation of the second transmission member 2, and the second transmission member 2 will not drive the first transmission member 1 to rotate and cause the driving device at the driving end to passively rotate and be damaged.

[0057] The clutch transmission mechanism mentioned above is adopted, and the first transmission member 1 and the second transmission member 2 are matched with each other through the clutch hanging tongue 3, and the clutch hanging tongue 3 and the bite surface and the disengagement surface on the first transmission member 1 are used to realize the functions of one-way transmission and reverse disengagement, which has a simpler structure, is convenient to manufacture and has a lower cost; moreover, the transmission between the first transmission member 1 and the second transmission member 2 is stable, and the disengagement is smooth, which effectively avoids damage to the driving part of the drain basket and improves the working stability and service life of the drain basket. The clutch mechanism of the drain basket can also facilitate the disassembly and assembly of the power source and the main part of the drain basket, and the power source of the drain basket can be disassembled for other uses, so as to realize multiple uses of one machine.

[0058] like Figures 1 to 4 As shown, specifically in this embodiment, the first occlusal surface 1a and the first disengagement surface 1b are inclined surfaces respectively arranged on both sides of the inclined convex rib 1-1, and the second occlusal surface 3a is an inclined surface with the same inclination direction as the first occlusal surface 1a, so that the first occlusal surface 1a and the second occlusal surface 3a can produce a stable occlusal effect when they move relative to each other; the second disengagement surface 3b is an arc surface arranged on the opposite side of the corresponding second occlusal surface 3a, and the arc surface structure of the second disengagement surface 3b cooperates with the inclined surface structure of the first disengagement surface 1b to produce a radial component force, thereby pushing the clutch tongue 3 to separate from the first transmission member 1. In order to better provide the component force for the contraction of the clutch tongue 3, refer to Figure 6 and Figure 7 As shown, the clutch tongue 3 is preferably offset from the radial position of the second transmission member 2 to the rotation direction of the second transmission member 2 by a certain distance, so that when the first transmission member 1 and the second transmission member 2 generate relative rotational motion, the first disengagement surface 1b can act on the clutch tongue 3 at a smaller angle to provide a larger component force to shrink the clutch tongue 3. The above-mentioned design of the occlusal surface and the disengagement surface has a simple structure and is easy to manufacture.

[0059] like Figure 1 and Figure 2 As shown, in order to facilitate the insertion and removal of the first transmission member 1 in the center hole 2-1, the above-mentioned clutch tongue 3 is slidably arranged in the second transmission member 2 and is limited in an initial state where the front end extends into the center hole 2-1. The lower end outer edge of the first transmission member 1 is also provided with a first insertion guide surface 1c, and the upper end front side edge of the clutch tongue 3 is also provided with a second insertion guide surface 3c; the first insertion guide surface 1c and the second insertion guide surface 3c are both inclined surfaces or arc surfaces. When the first transmission member 1 is axially inserted into the center hole 2-1 at any angle, the first insertion guide surface 1c and the second insertion guide surface 3c can cooperate to generate a thrust in the opposite direction of the elastic force of the elastic member 4 to enable the first transmission member 1 to be smoothly inserted into the center hole 2-1, thereby facilitating the insertion and removal of the first transmission member 1 and the second transmission member 2, and making the operation simpler and more convenient. Further, in combination with Figure 3 and Figure 5In the above initial state of the clutch tongue 3, the diameter of the concentric circle M1 of the center hole 2-1 where the front end of the clutch tongue 3 is located is larger than the diameter of the circle M2 where the root of the oblique convex rib 1-1 on the first transmission member 1 is located, and smaller than the diameter of the circle M3 where the outer wall of the oblique convex rib 1-1 on the first transmission member 1 is located, so that the clutch tongue 3 and the first transmission member 1 can maintain a relatively flexible matching state, and the clutch tongue 3 only cooperates with the oblique convex rib 1-1 to achieve power transmission or separation, which further facilitates the plugging and unplugging operation of the first transmission member 1 and the second transmission member 2. Further preferably, the diameter of M1 is slightly larger than the diameter of M2 to ensure the bite area of ​​the first bite surface 1a and the second bite surface 3a.
