Description

Technical Field

[0001] This utility model relates to the field of cooking tableware technology, specifically to a double-layer rotating solid-liquid separation spoon. Background Technology

[0002] Currently, during the cooking process, especially when scooping soup, it is often necessary to separate the broth from the solid ingredients. The traditional method involves using both a ladle and a strainer, which is cumbersome and takes up too much space. While some integrated strainers exist on the market, their functions are mostly limited and fixed.

[0003] Authorization announcement number CN217565821U discloses a soup spoon. Referring to its description and accompanying drawings, the spoon includes a spoon body, a filter screen, and a handle. The filter screen can be stacked with the spoon body. The spoon also includes a spoon connecting rod connecting the spoon body to a first end of the handle and a filter screen connecting rod connecting the filter screen to a second end of the handle. The filter screen connecting rod can rotate relative to the handle, causing the filter screen to rotate to one side of the spoon body. The filter screen functions to filter liquid.

[0004] However, the solution still has some limitations: 1. When using this method to filter solids from soup or food, whenever the ladle is tilted, because the area of ​​the filter screen is smaller than the ladle body, solids inside the ladle body are prone to not falling onto the filter screen, causing the filtering function between soup and solids to fail; 2. The filtering mode of this solution is relatively simple. When the ladle body is full of soup, it will inevitably pick up solids first, making it impossible to filter most of the solids in time when scooping; 3. The mesh size of the filter screen in this solution is fixed, and users cannot adjust the filtering precision according to the actual food needs. Summary of the Invention

[0005] This invention addresses the problems encountered in the use of soup spoons by proposing a double-layer rotating solid-liquid separation spoon. While retaining the basic functions of a normal soup spoon, it achieves a multi-functional soup spoon that integrates scooping, multi-stage filtration, and real-time filtration, making it portable and more efficient during operation.

[0006] The objective of this invention is achieved through the following technical solution: a double-layer rotary solid-liquid separation spoon, comprising a first spoon head and a second spoon head, wherein the first spoon head is nested inside the second spoon head, the surface of the second spoon head is provided with a plurality of filter channels, a second connecting rod extends outward from one side of the second spoon head, a first connecting rod is coaxially disposed on one side of the first spoon head and passes through the second connecting rod, and a handle mechanism is provided on the outside of the second connecting rod, wherein the handle mechanism is provided with a tooth groove adapted to the protruding teeth on the side wall of the first connecting rod, and the handle mechanism can drive the first connecting rod to rotate relative to the second connecting rod when rotating relative to the second connecting rod.

[0007] Preferably, the grip mechanism includes a hollow first grip body, a second grip body, and a handle assembly. The cross-sectional shape of the first grip body is a flat-mouthed right-angled oblique truncated cone, and the cross-sectional shape of the second grip body is a cylinder. A pin at one end of the second grip body is hinged to the interior of the first grip body. A limiting plate is provided at the end of the pin. The interior of the first grip body is also provided with an annular toothed groove, which engages with the protruding teeth on the side wall of the first connecting rod. The first grip body is fixedly connected to the surface of the second connecting rod. The second grip body is also provided with a handle assembly that can lock the first grip body.

[0008] Preferably, the first connecting rod is provided with an annular boss, the second connecting rod is provided with an annular groove adapted to the annular boss, and the second connecting rod is also provided with a first rolling bearing coaxial with the first connecting rod, the inner ring of the first rolling bearing being in contact with the surface of the first connecting rod.

[0009] Preferably, the end of the first connecting rod is connected to a second rolling bearing inside the first handle body, and the first connecting rod is also provided with a transmission gear, the teeth of which mesh inside the annular tooth groove.

[0010] Preferably, the cross-sections of the first and second spoon heads are semi-circular, and the surface of the second spoon head has several filtering channels, which are divided into first filtering channels and second filtering channels with different diameters. The several first filtering channels and several second filtering channels are respectively set in half of the surface of the second spoon head with the axis of the first connecting rod as the boundary. The filter channel is divided into a first filter channel and a second filter channel with different diameters, and each is arranged in half of the surface of the second spoon head, so that a spoon has at least two filtration accuracies (coarse filtration and fine filtration). Users can selectively expose different filtration areas by simply rotating the first spoon head, which can meet different needs from separating large pieces of food to filtering out fine impurities, greatly enhancing the practicality and adaptability of the product.

[0011] Preferably, the handle assembly includes a locking handle, an elastic element, and a support shaft. The surface of the first grip body is provided with a plurality of limiting slots in the rotational direction around the axis of the second grip body. The interior of the second grip body is provided with a grip inner groove. The inner groove of the grip inner groove is provided with an elastic element and a support shaft. The locking handle is hinged to the support shaft. During the rotation of the locking handle toward the surface close to the second grip body, it can compress the elastic element to produce deformation. The locking handle is provided with a limiting boss inside any of the limiting slots. The locking handle, hinged to the pivot and equipped with a spring element, enables one-button unlocking and automatic reset upon release. Users can operate it with just one hand, making it extremely convenient. The limiting protrusion on the locking handle, embedded in a limiting slot, provides a robust mechanical lock, ensuring that it will not rotate accidentally under stress such as scooping or holding.

[0012] Preferably, the locking handle is provided with a circular support plate and a torsion spring pressure plate on the side near the inner groove of the grip. The circular support plate is hinged to the support shaft. The elastic element is a torsion spring. The inner groove of the grip is also provided with a torsion spring support column. After the torsion spring is installed on the torsion spring support column, one end of the torsion spring is attached to the inner wall of the inner groove of the grip and the other end of the torsion spring is attached to the torsion spring pressure plate. During the rotation of the locking handle toward the surface close to the second grip body, the torsion spring pressure plate can compress the torsion spring to produce deformation. By incorporating a torsion spring support column and a torsion spring pressure plate, the pressing action of the locking handle is efficiently converted into the deformation of the torsion spring, and the restoring force is directly fed back to the locking handle through the torsion spring pressure plate. The circular support plate ensures the stability of the locking handle's rotation around the support axis. The entire structure is compact and can be completely accommodated within the grip's inner groove without increasing the volume of any additional components.

[0013] Preferably, the first and second spoon heads are made of stainless steel, and the first handle body and the second connecting rod are provided with coaxial screw mounting holes. This design is intended to ensure that whenever the limiting protrusion at the end of the locking handle engages with the limiting slot on the first handle body, the first spoon head is subjected to force during use, and the transmission gear on the first connecting rod cannot drive the annular toothed groove. Therefore, the first spoon head cannot rotate when subjected to force during use, and the entire spoon can be used as a regular spoon.

[0014] Compared with the prior art, the present invention has the following beneficial effects: 1. The filtration process of this solution does not require tilting the entire ladle. After scooping up the soup and solids, the ladle is held horizontally above the container (i.e., the opening surfaces of the first and second ladle heads are parallel to the opening surface of the container). By rotating the first handle body, the first ladle head inside is rotated, thereby gradually exposing the filter channel on the second ladle head. The soup and solids in the first ladle head fall naturally under the action of gravity and all fall onto the inner surface of the second ladle head. The soup flows into the container below through the filter channel, while all solids are intercepted by the large filter screen of the second ladle head. Since the entire process is not tilted, the solids have no other way to escape, ensuring that the filtration function is completely effective and solving the problem of filtration failure caused by tilting in traditional designs. 2. The surface of the second scoop head is equipped with a first filter channel (small gap) and a second filter channel (large gap) of different diameters, integrating two different precision filters into one component. By rotating the first handle body in different directions, the user can selectively expose either the first or second filter channel area for operation. Coarse filtration mode: using the second filter channel, large solids (such as ginger slices and meat chunks) are quickly filtered out, while smaller suspended matter is retained, resulting in a rich broth. Fine filtration mode: using the first filter channel, fine impurities (such as chili seeds and spice fragments) are filtered out, resulting in a clear broth. This allows one scoop to provide at least two selectable filtration precisions, which users can flexibly adjust according to actual food needs (such as cooking for adults or preparing food for children or patients), perfectly solving the problem of poor adaptability of fixed mesh size filters. 3. A cleverly incorporated cleaning mode, or real-time filtration mode, allows for simultaneous scooping and filtering: If you don't want to scoop the mixture into the soup ladle before filtering, simply rotate the first handle to adjust the opening of the first ladle head to be below the area of ​​the second ladle head furthest from the filter screen. Immerse the ladle directly into the soup pot to scoop. As the ladle moves across the soup, the broth, under fluid pressure, actively passes through the filter screen of the second ladle head (essentially a movable filter head) and enters the internal cavity of the first ladle head. Solid ingredients in the broth are effectively blocked outside the second ladle head by the filtration channel. When you lift the ladle, the first ladle head contains filtered, clean broth. This design combines scooping and filtering into one action, eliminating intermediate steps and greatly improving operational efficiency. It perfectly solves the problem of not being able to filter instantly while scooping. Additionally, in this mode, the entire ladle can be rinsed under running water, allowing the water flow to directly penetrate the filtration channel of the second ladle head and thoroughly wash away any remaining impurities. 4. Regarding the soup spoon with a filtering function, when the first and second spoon heads overlap, the angle is fixed by the locking mechanism of the handle assembly (the principle is the same as the grip fixation when switching to filtering mode). The first and second handle bodies are firmly locked by the limiting protrusions. At this time, the entire spoon is a rigid whole and will not wobble or rotate during use. Its overall shape is no different from an ordinary semi-circular soup spoon, providing the same stability as a traditional soup spoon. The second handle body is designed in a traditional cylindrical shape and has anti-slip grooves. When the user is not performing filtering operations, this structure conforms to the user's long-established muscle memory and usage habits. The user can use it to scoop soup, oil, water, or liquid foods with solid ingredients just like any traditional soup spoon, and its basic scooping function is not weakened.

[0017] The present invention will be further described below with reference to the embodiments shown in the accompanying drawings: like Figure 1 , Figure 3 , Figure 5 and Figure 7As shown, a double-layer rotary solid-liquid separation spoon includes a first spoon head 1 and a second spoon head 2. The first spoon head 1 and the second spoon head 2 are made of stainless steel. The first spoon head 1 is nested inside the second spoon head 2. The cross-section of the first spoon head 1 and the second spoon head 2 is semi-circular. The volume of the second spoon head 2 is larger than that of the second spoon head 1, and there is a certain gap between the second spoon head 2 and the second spoon head 1. This arrangement makes it less likely for the first spoon head 1 to interfere with the rotation inside the second spoon head 2.

[0018] In this embodiment, the surface of the second spoon head 2 is provided with a plurality of filter channels; specifically, the plurality of filter channels on the surface of the second spoon head 2 are divided into first filter channels 201 and second filter channels 202 with different diameters. The diameters of the first filter channels 201 and the second filter channels 202 can be adaptively adjusted according to the actual set filtration precision. In this embodiment, the gap of the first filter channel 201 is smaller than that of the second filter channel 202, so the filtration effect of the first filter channel 201 is better; the plurality of first filter channels 201 and the plurality of second filter channels 202 are respectively arranged in half of the surface of the second spoon head 2 with the axis of the first connecting rod 11 as the boundary; In order to further support and guide the first spoon head 1 and the second spoon head 2 during rotation and limit the rotation angle, a second connecting rod 21 is provided extending outward from one side of the second spoon head 2, and a first connecting rod 11 is coaxially provided on one side of the first spoon head 1, passing through the second connecting rod 21. To facilitate the subsequent separation of condiments and soup, the lower surface of the second spoon head 2 is often suspended above the bowl or other container when the first spoon head 1 and the second spoon head 2 are in an overlapping state, keeping the opening surfaces of the first spoon head 1 and the second spoon head 2 parallel to the opening surfaces of the container. In the process of separating condiments and soup, it is necessary to ensure that when the first connecting rod 11 rotates relative to the inside of the second connecting rod 21, the first connecting rod 11 can simultaneously drive the first spoon head 1 to rotate inside the second spoon head 2. It should be noted that the first connecting rod 11 is provided with an annular boss 111, the second connecting rod 21 is provided with an annular groove adapted to the annular boss 111, and the second connecting rod 21 is also provided with a first rolling bearing 211 coaxial with the first connecting rod 11. The inner ring of the first rolling bearing 211 is in contact with the surface of the first connecting rod 11. With this configuration, the annular boss 111 of the first connecting rod 11 and the annular groove inside the second connecting rod 21 serve as guides and limits, preventing the first connecting rod 11 from radially translating relative to the second connecting rod 21.

[0019] Please continue to refer to the reference. Figure 2 and Figure 3The second connecting rod 21 is covered with a handle mechanism 3. The handle mechanism 3 includes a hollow first handle body 31, a second handle body 32, and a handle assembly 33. The cross-sectional shape of the first handle body 31 is a flat-mouthed right-angled oblique cone. This design is to facilitate hand grip and rotation when rotating the first handle body 31. The cross-sectional shape of the second handle body 32 is a cylinder. This design is to retain the general structure of a soup spoon and facilitate the user's own usage habits. When the first spoon head 1 is not rotating relative to the second spoon head 2, the surface of the second handle body 32 directly contacts the user's hand, and the surface of the second handle body 32 is provided with grooves to increase friction. The pin 321 at one end of the second grip body 32 is hinged to the inside of the first grip body 31. The end of the pin 321 is provided with a limiting plate 322. This setting enables the first grip body 31 to rotate relative to the second grip body 32. Because the grip mechanism 3 has a toothed groove adapted to the protruding teeth on the side wall of the first connecting rod 11, the grip mechanism 3 can drive the first connecting rod 11 to rotate relative to the second connecting rod 21 when it rotates. Specifically, the first grip body 31 also has an annular toothed groove 311 inside, and the end of the first connecting rod 11 is connected to the second rolling bearing 312 inside the first grip body 31. At the same time, the first connecting rod 11 also has a transmission gear 112, and the teeth of the transmission gear 112 mesh with the inside of the annular toothed groove 311. It should be noted that the first grip body 31 is fixedly connected to the surface of the second connecting rod 21. The first grip body 31 and the second connecting rod 21 are provided with coaxial screw mounting holes 34. By installing fastening screws inside the screw mounting holes 34, the first grip body 31 and the second connecting rod 21 are fixed together. Please combine Figure 3 and Figure 4 During implementation, when the first spoon head 1 needs to rotate relative to the second spoon head 2 to adjust its usage state: the hand grips the first handle body 31 and rotates it. As the first handle body 31 rotates, it simultaneously drives the internal annular toothed groove 311 to rotate. During rotation, the annular toothed groove 311 transmits power to the teeth of the transmission gear 112 through the internal gear ring, causing the transmission gear 112 to rotate. During rotation, the transmission gear 112 simultaneously drives the first connecting rod 11 to rotate, which in turn drives the first spoon head 1 to rotate relative to the second spoon head 2. Ultimately, different angles between the first spoon head 1 and the second spoon head 2 can result in at least four usage states: The first mode is the normal scooping mode. In this mode, the first spoon head 1 and the second spoon head 2 are completely overlapped, and the solid bottom of the first spoon head 1 completely covers the first filter channel 201 and the second filter channel 202 on the surface of the second spoon head 2. At this time, the inside of the first spoon head 1 acts as a complete, watertight container, and its function is no different from that of an ordinary soup spoon. It can be used to scoop up whole soups with ingredients or to transfer liquids such as water and oil, as well as ingredients.

[0020] The second type (with) Figure 5 (Based on direction): Coarse filtration mode: First, scoop the soup and ingredients together with the first spoon head 1. Then, suspend the lower surface of the second spoon head 2 above the bowl or other container, keeping the opening surfaces of the first spoon head 1 and the second spoon head 2 parallel to the opening surface of the container. Next, rotate the first handle body 31 counterclockwise, thereby driving the first spoon head 1 to rotate: the first spoon head 1 rotates counterclockwise relative to the second spoon head 2, so that the second filter channel 202 area on the second spoon head 2 is gradually exposed. During the rotation, the soup and ingredients in the first spoon head 1 will fall together onto the surface of the second spoon head 2. However, since the second filter channel 202 on the second spoon head 2 has gaps, the soup will fall, but the ingredients will be blocked by the second spoon head 2. The volume of soup and ingredients in the first spoon head 1 is already fixed. In addition, since there is no need to tilt the entire spoon during the entire soup pouring process, this structural design makes it almost impossible for the ingredients to cross the second spoon head 2 or slide off the side of the second spoon head 2 under the action of gravity, thus fully ensuring the normal operation of the filtering function. The second method often requires quickly filtering out larger solid ingredients, such as ginger slices, scallion segments, large pieces of spices, and chunks of meat, while retaining smaller suspended matter in the soup (such as some vegetable pieces and oil) to make the soup taste richer. Large pieces of auxiliary materials are intercepted in the second spoon head 2. The auxiliary materials intercepted in the second spoon head 2 are poured back into the pot or discarded.

[0021] The third type (with) Figure 5 (Based on direction): Fine filtration mode: Similarly, first scoop the soup and ingredients together with the first spoon head 1, then let the lower surface of the second spoon head 2 hang above the bowl or other container, keeping the opening surfaces of the first spoon head 1 and the second spoon head 2 parallel to the opening surface of the container; then rotate the first handle body 31 clockwise, thereby driving the first spoon head 1 to rotate: the first spoon head 1 rotates clockwise relative to the second spoon head 2, so that the first filter channel 201 area on the second spoon head 2 is gradually exposed; The subsequent rotating filtration process is the same as in the second case, so it will not be described again here; the third mode is often used to obtain extremely clear broth for high-grade clear soup, thickening, or for patients or young children, to filter out small impurities such as chili seeds and small spice fragments.

[0022] The fourth type (with) Figure 7 (For reference only): Cleaning mode or real-time filtration mode: Before serving soup, rotate the first handle body 31 counterclockwise or counterclockwise to rotate the first spoon head 1 until the opening of the first spoon head 1 is rotated to the position below the second spoon head 2 away from the filter area. Next, immerse the entire ladle in the soup pot. As the ladle moves across the soup, the broth, under fluid pressure, passes through the filter of the second ladle head 2 (or, depending on the need, the first filter channel 201 or the second filter channel 202 with the area facing forward) and enters the cavity of the first ladle head 1. The chili peppers and other solid ingredients in the broth are effectively blocked by the filter channel. When the entire ladle is lifted, the broth in the first ladle head 1 has been filtered and can be poured directly into a bowl. This process combines the two actions of scooping and filtering into one, eliminating intermediate steps and improving operational efficiency. When taking soup from a pot of rich stew for specific diners (such as the elderly or children), it can effectively prevent unwanted ingredients from being scooped out along with the soup.

[0023] Of course, in the fourth mode, the entire spoon can also be rinsed under the tap. The water flow can directly penetrate the filter channel of the entire second spoon head 2 and thoroughly wash away any residual impurities attached to it.

[0024] In order to further ensure that the second handle body 32 cannot rotate relative to the first handle body 31 during daily use (or the first spoon head 1 is fixed when rotated to a designated position), the first connecting rod 11 must also not rotate inside the second connecting rod 21 in these situations; therefore, the second handle body 32 is also provided with a handle assembly 33 that can lock the first handle body 31. Please refer to the reference. Figure 3 and Figure 4 Specifically, the handle assembly 33 includes a locking handle 331, an elastic element 332, and a support shaft 333. The surface of the first grip body 31 is provided with a plurality of limiting slots 313 in the rotational direction around the axis of the second grip body 32. The interior of the second grip body 32 is provided with a grip inner groove 323. The interior of the grip inner groove 323 is provided with an elastic element 332 and a support shaft 333. The locking handle 331 is hinged to the support shaft 333. During the rotation of the locking handle 331 toward the surface close to the second grip body 32, it can squeeze the elastic element 332 to produce deformation. The interior of the locking handle 331 near any of the limiting slots 313 is provided with a limiting boss 334. like Figure 6As shown, when it is necessary to achieve rotation of the first spoon head 1 relative to the second spoon head 2, the axial restriction between the first handle body 31 and the second handle body 32 needs to be released: the user can hold the surface of the second handle body 32 with his right hand, and at the same time, the fingers of the right hand other than the thumb press the locking handle 331; when the locking handle 331 is pressed, the elastic element 332 deforms, and the limiting boss 334 at the end of the locking handle 331 moves away from the limiting slot 313 on the first handle body 31; at this time, the user's left hand holds the first handle body 31, realizing the rotation of the first handle body 31 relative to the second handle body 32.

[0025] When the first spoon head 1 rotates relative to the second spoon head 2 to a specified angle (in any of the above modes), it is necessary to re-implement the axial limiting between the first grip body 31 and the second grip body 32: like Figure 4 As shown, the user's right hand releases the locking handle 331; under the reaction force of the deformation generated by the elastic element 332, the limiting boss 334 at the end of the locking handle 331 re-engages into the limiting slot 313 on the first grip body 31; thus achieving axial limiting of the first grip body 31 relative to the second grip body 32.

[0026] To further disclose how the elastic element 332 resets the locking handle 331, the locking handle 331 is provided with a circular support plate 335 and a torsion spring pressure plate 336 on the side near the inner groove 323 of the handle. The circular support plate 335 is internally hinged to the support shaft 333. The elastic element 332 is a torsion spring. The inner groove 323 of the handle is also provided with a torsion spring support column 337. After the torsion spring is installed on the torsion spring support column 337, one end of the torsion spring is attached to the inner wall of the inner groove 323 of the handle and the other end of the torsion spring is attached to the torsion spring pressure plate 336. During the rotation of the locking handle 331 toward the surface near the second handle body 32, the torsion spring pressure plate 336 can compress the torsion spring to produce deformation. During the pressing or resetting process of the locking handle 331, the circular support plate 335 always acts as a support for the rotation of the pivot 333. When the locking handle 331 is in the pressing state, the torsion spring pressure plate 336 on the locking handle 331 will continuously squeeze the torsion spring. Since the torsion spring is limited by the boss on the torsion spring support column 337, the torsion spring is squeezed and deformed without deviating. When the downward pressure of the locking handle 331 disappears, the elastic force generated by the torsion spring will cause the limiting boss 334 at the end of the locking handle 331 to re-engage into the limiting slot 313 on the first grip body 31. Once the limiting protrusion 334 at the end of the locking handle 331 is engaged with the limiting slot 313 on the first handle body 31, the first handle body 31 and the second handle body 32 cannot rotate relative to each other. At this time, since the first handle body 31 and the second connecting rod 21 are fixedly connected by the screw mounting hole 34, the second spoon head 2 cannot rotate when subjected to force during use. At the same time, when the first spoon head 1 is subjected to force during use, the transmission gear 112 on the first connecting rod 11 cannot drive the annular toothed groove 311, so the first spoon head 1 cannot rotate when subjected to force during use, and the entire spoon is used as an ordinary spoon.

[0027] Working principle and usage of this utility model: Check if the first spoon head 1 and the second spoon head 2 are in the desired mode. If you need to switch modes, hold the second handle body 32 with one hand and press the locking handle 331 with the other hand to unlock. Then rotate the first handle body 31 to the specified position. After reaching the specified angle (switching between different modes), release the locking handle 331 so that it automatically resets and locks under the action of the elastic element 332.

[0028] Mode 1: Normal Scooping Mode Ensure that the first scoop head 1 and the second scoop head 2 are completely overlapped, and that the solid bottom of the first scoop head 1 completely covers all the filter channels of the second scoop head 2.

[0029] Just like a regular soup spoon, it can be used to scoop up soup, water, oil, and liquid foods containing solid ingredients. In this case, the spoon acts as a complete, leak-free container.

[0030] Mode 2: Coarse Filtering Mode In the normal scooping mode, scoop out soup with solid ingredients (such as ginger slices and scallion segments).

[0031] Hold the spoon horizontally above the receiving container. Press the locking handle 331 and rotate the first handle body 31 counterclockwise to gradually expose the second filter channel 202 area on the second spoon head 2. The soup is filtered out through the larger gaps, while large solids are trapped inside the second spoon head 2.

[0032] After filtration, pour the intercepted solids back into the pot or discard them.

[0033] Mode 3: Fine Filtering Mode In the normal scooping mode, scoop out the soup containing small impurities (such as chili seeds and spice crumbs).

[0034] Hold the spoon horizontally above the receiving container. Press the locking handle 331 and rotate the first handle body 31 clockwise to gradually expose the first filter channel 201 area on the second spoon head 2. The broth is filtered out through the smaller gaps to obtain clear broth.

[0035] After filtering, clean the fine residue trapped in the second spoon head 2.

[0036] Mode 4: Real-time Filtration Mode (Cleaning Mode) Press the locking handle 331 and rotate the first handle body 31 to rotate the opening of the first scoop head 1 to the area below the second scoop head 2 away from the filter area (see reference). Figure 7 The first filter channel 201 or the second filter channel 202 area can be oriented in the forward direction as needed.

[0037] The entire ladle in this state is directly immersed into the soup pot and swirls across the soup. Under fluid pressure, the soup penetrates the filter channel of the second ladle head 2 and enters the interior of the first ladle head 1, while solid ingredients are blocked from entering.

[0038] Lift the ladle; the first spoonful contains the filtered broth, which can be poured directly into a bowl. This mode also makes it easy to rinse and clean under running water.

[0039] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to replace them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.
