Embodiment 1:

As shown in Fig. 1-5, a filter spoon provided in this embodiment includes a spoon body 1 and a tube cover 2. An inner tube 11 extending upward from the bottom of the spoon is provided in the spoon body 1. The lower end of the inner tube 11 passes through the bottom of the spoon and forms an outlet 12. The tube cover 2 is a structure with a closed upper portion and an open lower end. The inner diameter of the tube cover 2 is larger than the outer diameter of the inner tube 11 so that the tube cover 2 can cover the outer portion of the inner tube 11 and form a siphon channel 21 between the two. The cross-sectional area of the siphon channel 21 is larger than or equal to the inner cross-sectional area of the inner tube 11, and the tube cover 2 can be limited by a support frame. The siphon channel 21 is The lower part of the channel 21 can be connected to the outside of the tube cover 2 as an inlet 22 through the gap formed between the lower end of the tube cover 2 and the bottom of the spoon, and the upper part of the siphon channel 21 is connected to the inner tube 11 through the connecting port 111 set on the upper part of the inner tube 11. The support frame is an inner support frame, which is an independent movable component, including an Ω-shaped support frame 3 made of elastic material in one piece, and the middle gourd mouth of the Ω-shaped support frame 3 can be elastically embedded on the outside of the inner tube 11, and the two side walls of the Ω-shaped support frame 3 are used to elastically abut against the outer wall of the tube cover 2. In this embodiment, the filter spoon is preferably made of metal, and the inner tube 11 is welded to the spoon body 1. In other embodiments, the inner tube can also be integrally formed with the spoon body, or detachably connected to the spoon body by threaded connection or other methods.

The filter spoon provided in this embodiment is used by pouring liquid into the spoon body 1 or directly scooping liquid with the spoon body 1. When the liquid level does not exceed the connecting port 111 on the inner tube 11, the liquid will not flow out from the outlet 12. At this time, the spoon body 1 can accumulate liquid. During the accumulation of liquid, it can be transferred to a designated position for filtering (for example, filtering the clear soup in the oil soup into a bowl), or allowing the object in the liquid to be fully soaked (for example, when making tea or Chinese medicine), or immersing the object to be cleaned in the liquid for cleaning (for example, when washing rice). The time of this process can be flexibly controlled as needed. When it is necessary to filter out the liquid, the liquid level can be raised to exceed the highest point of the inner cavity of the pipe cover 2 (that is, the siphon starting liquid level). The pipe cover 2 and the inner tube 11 will be quickly filled with liquid and the air therein will be emptied, and then the siphon effect will be triggered to continuously discharge the liquid through the outlet 12 at the bottom of the spoon. There are many ways to raise the liquid level, which can be achieved by directly adding liquid to the spoon body 1 or soaking objects, or by tilting the spoon body 1 so that the liquid level submerges the inner cavity of the pipe cover 2. In the process of filtering out the liquid by the siphon effect, since the floating objects (such as oil film) in the liquid float on the upper surface of the liquid, the floating objects basically will not enter the pipe cover 2 from the inlet 22. Therefore, the liquid flowing out from the outlet 12 is all filtered liquid, until the liquid level outside the pipe cover 2 drops back to the height of the inlet 22, the inlet 22 is connected to the atmospheric environment to make the siphon effect disappear, and the liquid in the pipe cover 2 will quickly fall back and stop flowing out. In this process, even if the floating objects enter the pipe cover 2, they basically will not pass through the connecting port 111 on the upper part of the inner tube 11 and then be discharged. Therefore, the filtering of the floating objects can be basically completely achieved. Moreover, in the whole process, the sediment in the liquid (such as bone residue in the oil soup, tea leaves in the tea soup, and washed objects) is all settled at the bottom of the spoon. Even if it enters the pipe cover 2, it basically will not pass through the highest point and then be discharged from the outlet 12. Therefore, the filtering of the sediment can be basically completely achieved. It can be seen that during the whole process, the user does not need to continuously pay attention to the residual amount of liquid in the spoon body 1 and continuously change the tilt angle according to the residual amount to filter out the liquid. The user may even not need to continuously hold the spoon body 1, but directly place the spoon body 1 on other containers to receive the filtered liquid by the other containers. In addition, based on the above functions, the spoon body 1 provided by the present invention can be used for other purposes in addition to filtering floating objects and sediments in liquids, such as washing objects. When the liquid in the spoon body 1 does not reach the siphon start level, the object can be washed in the spoon body 1. After washing is completed, the liquid level in the spoon body 1 is raised to the siphon start level, and the liquid can be automatically discharged under the siphon action, leaving the washed object.

It can be seen that the filter spoon provided in this embodiment has the following advantages: it has both filtering function and liquid accumulation function, so that the liquid can be transferred to a designated position for filtering, and can also meet the use requirements of immersing or cleaning an object in a liquid for a period of time and then starting the filtering function to discharge the liquid. Moreover, it can not only filter the sediment in the liquid, but also filter the oil. The pipe cover 2 is supported and limited by the inner support frame, so it is not easy for the pipe cover 2 to shake or move. The inner support frame is an independent movable part, which can be manufactured and cleaned separately. The manufacturing process is simple, and the cleaning is convenient without dead corners. Moreover, the gap between the lower port of the pipe cover 2 and the bottom of the spoon is used as the inlet 22 of the siphon channel 21, and there is no need to set a through hole or notch on the side wall of the pipe cover 2, which can reduce the processing difficulty and will not damage the structural strength of the pipe cover 2.

As a preferred embodiment, the upper end of the Ω-shaped support frame 3 protrudes from the upper end of the inner tube 11 and enables the pipe cover 2 to be mounted on the inner tube 11 and the bottom of the spoon, so that a gap can be formed between the pipe cover 2 and the bottom of the spoon as the inlet 22. The advantage of this design is that it can achieve accurate positioning of the axial position of the pipe cover 2, and it is convenient to form a gap of a stable height between the lower end of the pipe cover 2 and the bottom of the spoon as the inlet 22, which is convenient for operation.

As a preferred embodiment, the outer side wall of the spoon body 1 is further provided with a handle 13, and the handle 13 includes a support portion 131 extending radially outward from the lower portion of the side wall of the spoon body 1, and the bottom of the spoon body 1 is further provided with at least two supporting feet 14 distributed along the circumferential direction, wherein at least one supporting foot 14 is located on the other side opposite to the side where the handle 13 is located, and the lower end of the inner tube 11 passes through the bottom of the spoon and protrudes downward for a distance to form a protruding section 112, and the height of the protruding section 112 is lower than the height of the supporting feet 14 to raise the spoon body 1. The advantage of this design is that it is easy to operate. When the spoon body 1 needs to be placed on a container with a larger diameter, no other bracket is needed. The handle 13 can be used in conjunction with the spoon body 1 to place the spoon body 1 above the large-diameter container, making it suitable for a wider range of container diameters. The support feet 14 on the other side of the handle 13 can be hung on the outer edge of the container below to form a limit to prevent slipping, and the design is stable and reliable. In addition, the protruding section 112 can prevent the liquid flowing out of the outlet 12 from hanging on the wall outside the bottom of the spoon or flowing along the outside of the bottom of the spoon, thereby affecting the user experience. The height of the protruding section 112 is lower than the height of the supporting structure, thereby preventing the protruding section 112 from touching the bottom when the spoon body 1 is placed.

As a preferred embodiment, the inner tube 11 is eccentrically arranged near the inner wall of the spoon body 1 . The advantage of this design is that the inner tube 11 is eccentrically arranged, and when the liquid level in the spoon body 1 does not reach the siphon starting level, the spoon body 1 can be tilted downward toward the side where the inner tube 11 is located so that the liquid can submerge the highest point of the inner cavity of the tube cover 2 without overflowing from the spoon mouth, thereby starting the siphon. Therefore, the siphon effect can be activated to filter out the liquid even for a small amount of liquid, and the operation is convenient. In addition, when the siphon effect is used to filter out the liquid, the liquid can be gathered in the corner on the side where the inlet 22 is located by tilting the spoon body 1 downward toward the side where the inner tube 11 is located, so that the time for the inlet 22 to be exposed to the atmosphere can be delayed, thereby delaying the filtration termination time, and filtering out as much liquid in the spoon body 1 as possible. In addition, the spoon body 1 can be tilted upward toward the side where the inner tube 11 is located so that the liquid can be moved away from the corner on the side where the inlet 22 is located, and the time for the inlet 22 to be exposed to the atmosphere can be advanced, thereby terminating the siphon effect in advance, and flexibly controlling the time for terminating the filtered liquid. In addition, the eccentric arrangement of the inner tube 11 minimizes the impact on the storage function and visual impact of the spoon body 1.

As a preferred embodiment, a shielding portion or a spoon cover is provided above the side wall of the spoon body 1 near the inner tube 11, so that the liquid in the spoon body 1 is not easy to flow out from the spoon mouth when the spoon body 1 is tilted downward toward the inner tube 11. The drawings of this embodiment are omitted, and those skilled in the art can implement it according to this technical solution, which has the advantage that by providing the shielding portion, the spoon body 1 can be tilted downward toward the side where the inner tube 11 is located at a greater angle, so that the liquid exceeds the siphon starting liquid level to start the siphon, and at the same time, the liquid will not overflow from the spoon mouth under the action of the shielding portion.

As a preferred embodiment, the bottom of the spoon body 1 is provided with an inclined surface or a stepped structure so as to form a concave position, the inner tube 11 is arranged in the concave position, and an emptying port and a first sealing cover capable of sealing the emptying port are also arranged at the concave position. The drawings of this embodiment are omitted, and those skilled in the art can implement it according to this technical solution, which has the advantages of being able to minimize the amount of liquid remaining in the spoon body 1 after the liquid is siphoned out, and the sediment is also gathered in the concave position for easy processing.

As a preferred embodiment, the upper part of the pipe cover 2 is provided with a pressure relief port connecting the inside and outside of the pipe cover 2, and the pressure relief port can be manually blocked and sealed or opened by an operator, or a second sealing cover or valve is provided at the pressure relief port. The drawings of this embodiment are omitted, and those skilled in the art can implement it according to the technical solution, which has the advantage that by providing the pressure relief port, when it is necessary to quickly stop the filtration of liquid, the inner cavity of the pipe cover 2 can be directly connected to the atmospheric environment by opening the pressure relief port to stop the siphon effect, thereby stopping the filtration.

Embodiment 2:

Based on the technical solution of Example 1, the following improvements are made:

As shown in FIG6 , the two side walls of the Ω-shaped support frame 3 are also provided with two outwardly bent edges 32, which are used to support the lower end of the pipe cover 2, so that the pipe cover 2 can be suspended above the bottom of the spoon and a gap is formed between the lower end of the pipe cover 2 and the bottom of the spoon as the inlet 22. The advantage of this design is that by providing the folded edges 32 to support the pipe cover 2, the axial position of the pipe cover 2 can be accurately positioned, and a gap of a stable height can be formed between the lower end of the pipe cover 2 and the bottom of the spoon as the inlet 22, which is easy to operate and can reduce the manufacturing process requirements for matching accuracy.

Embodiment 3:

Based on the technical solution of Example 2, the following improvements are made:

As shown in FIGS. 7-8 , the bottom of the two side walls of the Ω-shaped support frame 3 is provided with a first extension section 33 extending downward, and the first extension section 33 is used to abut the bottom of the spoon body 1 to achieve axial limitation of the Ω-shaped support frame 3, so that the gourd-shaped support frame 3 The inner ring 31 of the gourd-shaped support frame 3 can be suspended above the root 113 of the inner tube 11, and a folded edge 32 is respectively provided at both ends of each extension section, thereby forming four folded edges 32. The advantage of this design is that, if the filter spoon is made of metal, the lower end of the inner tube 11 is generally welded to the bottom of the spoon, so a weld bulge will be formed at the root 113 of the inner tube 11, and the height of the weld bulge is uncertain. By setting the first extension section 33, the gourd-shaped support frame 3's gourd-shaped inner ring 31 is suspended above the root 113 of the inner tube 11, so that the axial position of the Ω-shaped support frame 3 is not affected by the weld bulge at the root 113 of the inner tube 11, thereby facilitating precise positioning of the axial position of the pipe cover 2 and achieving a stable size of the inlet 22; the design of the four folded edges 32 makes the support of the pipe cover 2 more stable.

Embodiment 4:

Based on the technical solution of Example 3, the following improvements are made:

As shown in Figs. 9-10, a second extension section 34 extending upward is provided at the top of the gourd-shaped inner ring 31 of the Ω-shaped support frame 3, replacing the folding edge 32 in the previous embodiment. The second extension section 34 is used to abut the middle area of the top of the inner side wall of the pipe cover 2 to achieve axial positioning of the pipe cover 2, so that the pipe cover 2 can be suspended above the spoon bottom and a gap is formed between the lower end of the pipe cover 2 and the spoon bottom as the inlet 22. The advantage of this design is that if the pipe cover 2 is made of metal material by stamping, the intersection of the top and the side wall of the pipe cover 2 generally has an arc chamfer or the side wall of the pipe cover 2 is a trumpet-shaped structure that continuously expands toward the outlet 12. By providing the second extension section 34 at the top of the gourd-shaped inner ring 31 of the Ω-shaped support frame 3 to support the pipe cover 2, the second extension portion 422 supports the middle area of the top of the pipe cover 2, which can avoid the side wall of the pipe cover 2 or the intersection of the side wall and the top, avoid uncertainty, and facilitate accurate positioning of the axial position of the pipe cover 2 to achieve a stable size inlet 22.
