Description

Technical Field

[0001] This utility model relates to the field of food processing equipment technology, specifically to a draining device. Background Technology

[0002] In the food processing and daily catering industries, food draining is a common pre- or post-processing procedure. Its core requirement is to quickly separate food from residual liquids (such as washing water, soaking solution, etc.) while preventing food residue from clogging the draining structure.

[0003] In existing technologies, typical draining devices often employ a double-bowl structure, specifically comprising an outer bowl and an inner bowl, which are connected by a rotational mechanism to achieve relative movement. The inner bowl is designed as a spherical structure with multiple perforations on its surface for drainage, while the outer bowl serves as a support and liquid collection container. During operation, the food to be drained is placed in the inner bowl, and the outer bowl is flipped to allow the liquid inside the inner bowl to drain through the perforations, thus completing the draining process.

[0004] However, the above structure has significant drawbacks in practical applications: because the filter holes are directly exposed to the food contact surface, food residues (such as vegetable scraps, minced meat particles, and grain fragments) easily accumulate or become stuck in the filter holes during the draining process, leading to pore blockage. The direct consequences of this problem include:

[0005] Reduced drainage efficiency: When the filter holes become clogged, the liquid drainage rate slows down, requiring frequent interruptions in operation for cleaning;

[0006] Difficult to clean: The filter holes are densely arranged and have a small diameter. Once the residue clogs the filter, tools (such as fine needles and brushes) are needed to unclog them one by one. The operation is cumbersome and can easily damage the filter structure.

[0007] Hygiene risks: Residual food residue may breed bacteria, and cross-contamination must be strictly avoided, especially in food processing settings.

[0008] While existing technologies attempt to alleviate clogging by optimizing the distribution of filter holes or increasing their diameter, they are limited by the spherical structure of the inner bowl and the rotary operating logic, failing to fundamentally resolve the contradiction between residue clogging and ease of cleaning. Therefore, a new type of draining device is urgently needed that can ensure draining efficiency while achieving self-cleaning or convenient cleaning of the filter structure, thus overcoming the limitations of existing technologies. Utility Model Content

[0009] In view of this, the present invention provides a draining device that can clean the drain holes of the inner bowl while filtering water from food, thereby effectively avoiding subsequent cleaning work and indirectly increasing the filtration efficiency.

[0010] To solve the above-mentioned technical problems, this utility model provides a draining device, including an outer bowl and an inner bowl hinged inside the outer bowl. The inner bowl can rotate inside the outer bowl, and there is a sandwich space between the inner bowl and the outer bowl. Filter holes are provided through the inner bowl, and water in the inner bowl will be discharged through the filter holes.

[0011] The movable plate is slidably disposed within the interlayer space, and moves back and forth along the rim of the inner bowl.

[0012] The sealing cone is located on the side of the movable plate closest to the movable plate. After the movable plate moves to the inner plate, the sealing cone can seal the filter holes.

[0013] Both the filter holes and the sealing cone are conical in shape, which makes them easy to insert and also easy to clean.

[0014] A guide rod is provided at the rim of the outer bowl. The guide rod is vertically positioned and has a T-shaped structure. The end of the guide rod with a smaller cross-section is connected to the outer bowl. An arc-shaped connecting rod is slidably provided on the guide rod. The connecting rod will not rotate during the sliding process. The end of the connecting rod is connected to the end of the movable plate, and the connecting rod can drive the movable plate to slide.

[0015] The guide rod is located at the handle of the outer bowl, and the end of the connecting rod near the guide rod is also equipped with a force ring, which makes it easy to operate the filter bowl with nitrogen water.

[0016] A spring is also fitted on the guide rod. The spring is located between the end of the guide rod away from the outer cup and the connecting rod. The spring can push the connecting rod to reset.

[0017] A limiting structure is also provided between the outer bowl and the inner bowl to fix the position of the inner bowl. After the position of the inner bowl is limited, it is easy to insert the sealing cone into the filter hole.

[0018] The upper surface of the handle of the inner bowl is provided with a limiting groove, and a limiting plate is provided in the limiting groove. The sliding limiting plate can be fixed to the rim of the inner bowl.

[0019] In summary, compared with the prior art, this application includes at least one of the following beneficial technical effects:

[0020] 1. Self-cleaning function of water filter holes:

[0021] Through the design of the conical sealing cone and the conical filter hole, the sealing cone can perform a mechanical scraping action of "insertion-exit" on the filter hole during the reciprocating motion of the movable plate; that is, when inserted, the outer wall of the cone can physically break the residue attached to the inner wall of the filter hole.

[0022] 2. Operation logic optimization:

[0023] The combination of a spring return mechanism and a force-applying ring enables one-handed operation.

[0024] In the draining state: Under natural conditions, the spring keeps the movable plate in its initial position through the connecting rod, and the sealing cone maintains a safe distance of 3-5mm from the filter hole to ensure smooth drainage;

[0025] Cleaning state: Pressing the force ring with the thumb overcomes the spring force, driving the sealing cone to fully insert into the filter hole, simultaneously completing the sealing and cleaning actions. This ergonomic design reduces the time for a single cleaning operation to less than 0.8 seconds.

[0026] 3. Structural anti-clogging design:

[0027] The bottom of the inner bowl uses a flat filtration area instead of the traditional spherical structure, combined with a horizontally reciprocating movable plate.

[0028] The movement trajectory of the movable plate is arranged perpendicularly to the array of filter holes, ensuring that each filter hole receives at least 2 mechanical scrapings per cycle. Attached Figure Description

[0034] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the following will be described in conjunction with the accompanying drawings of the embodiments of this utility model. Figure 1-3 The technical solutions of the embodiments of this utility model are clearly and completely described herein. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the described embodiments of this utility model are within the protection scope of this utility model.

[0035] This embodiment provides a drainage device, such as Figure 1 , 2As shown: It includes an outer bowl 1 and an inner bowl 2 hinged inside the outer bowl 1. The inner bowl 2 can rotate inside the outer bowl 1, and a sandwich space 5 is formed between the inner bowl 2 and the outer bowl 1. Multiple water filter holes 3 are provided through the inner bowl 2, and water in the inner bowl 2 can be discharged through the water filter holes 3. A movable plate 4 is also slidably provided in the sandwich space 5. The movable plate 4 can slide towards the bowl opening until it fits against the bottom of the inner bowl. Multiple sealing cones 6 are provided on the side of the movable plate 4 near the inner bowl 2. The number of sealing cones 6 is the same as the number of water filter holes 3. That is, after the movable plate 4 moves towards the inner bowl 2, the sealing cones 6 can be inserted into the water filter holes 3, thereby cleaning the debris in the water filter holes 3. When there is water in the inner bowl 2, when the sealing part slides out of the water filter hole 3, it can also suck out the particulate debris from the water filter hole 3 through negative pressure.

[0036] Furthermore, both the filter hole 3 and the sealing cone 6 are conical structures, which means that when the sealing cone 6 is inserted into the filter hole 3, it can form an automatic guiding effect and also facilitate the sealing cone 6 to push out the debris in the filter hole 3.

[0037] Specifically, the outer bowl 1 has a vertical guide rod 7 at its rim, such as... Figure 1 , 2 As shown in Figure 3: The guide rod 7 has a T-shaped structure. The end of the guide rod 7 with a smaller cross-section is connected to the outer cup 1. The cross-section of the guide rod 7 is a polygonal structure. An arc-shaped connecting rod 8 is slidably provided on the guide rod 7. That is, a guide hole is vertically provided through the end of the connecting rod 8. The cross-section of the guide hole is also a polygonal structure. The guide rod 7 passes through the guide hole and is connected to the connecting rod 8. The connecting rod 8 can slide on the guide rod 7 and will not rotate during the sliding process. The other end of the connecting rod 8 is connected to the movable plate 4. The connecting rod 8 can drive the movable plate 4 to slide by moving up and down in the interlayer space 5.

[0038] Preferably, a spring 10 is also sleeved on the guide rod 7. The spring 10 is located between the end of the guide rod 7 with a larger cross section and the connecting rod 8, which facilitates the reset of the connecting rod 8 after it has slid. The guide rod 7 is located at the handle of the outer bowl 1, and the connecting rod 8 is also provided with a force-applying ring 9, which facilitates the draining of food with one hand.

[0039] Furthermore, a limiting structure is provided between the outer bowl 1 and the inner bowl 2 to fix the position of the inner bowl 2, such as... Figure 1 , 2 As shown: The upper surface of the handle of the inner bowl 2 is provided with a limiting groove 11, and a limiting plate 12 is provided in the limiting groove 11. When the limiting plate 12 is completely in the limiting groove 11, the inner bowl 2 can rotate normally inside the outer bowl 1. When the limiting plate 12 slides out, the edge of the limiting plate 12 can abut against the bowl surface of the inner bowl 2, thereby fixing the position of the inner bowl 2.

[0040] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0041] The above description is the preferred embodiment of this utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of this utility model, and these improvements and modifications should also be considered within the protection scope of this utility model.
