Description

Technical Field

[0001] The utility model relates to the technical field of kitchen utensils, and particularly to a filter net structure of an open oil cup. Background Art

[0002] As a container for edible oil, an oil pot is a commonly used tool in a household kitchen. The structural forms of household oil pots mainly include a narrow-mouth oil bottle and an open oil cup. Their mechanisms are different, and each has its own advantages and disadvantages in terms of function. The narrow-mouth oil bottle has a small oil outlet diameter, accurate oil output, and the bottle mouth is not easy to adhere to oil droplets. While the open oil cup is convenient for pouring edible oil, a relatively large amount of edible oil can be poured out in a short time, improving cooking efficiency. Adding edible oil to the open oil cup is also more convenient. Generally, a cup cover is provided on the open oil cup to prevent foreign objects from entering the oil cup. When pouring edible oil from the open oil cup, it is not easy to control the pouring amount. After pouring, oil droplets will adhere to the cup mouth and flow down along the cup wall, polluting the outer surface of the oil cup and the kitchen countertop. Therefore, in most cases, the open oil cup needs to be used in conjunction with a frying spoon, that is, using the frying spoon to take oil from the oil cup instead of pouring oil from the oil cup.

[0003] During the process of home cooking, there is a situation of reusing edible oil. For example, after frying food materials with edible oil, the used edible oil can be collected to obtain secondary oil and reused in subsequent cooking. The used edible oil after frying food materials contains food residues and needs to be filtered. In order to facilitate the filtration of edible oil, the existing open oil cups usually have a filter net. The outer edge of the filter net is matched with the cup mouth and can be placed on the cup mouth. The edible oil containing residues can be filtered through the filter net to obtain relatively pure secondary oil.

[0004] The existing filter oil cups effectively solve the problem of filtering residues of edible oil, but there are also some disadvantages in the setting of the filter net. For example, the storage problem of the filter net. Although the filter net fits well with the cup mouth and can be stably placed on the oil cup mouth, since it covers the cup mouth, it is not conducive to taking oil with a frying spoon. In many cases, the filter net needs to be removed and placed separately after use. This requires cleaning and storing the oil-soaked filter net. The filter net is usually supported by a frame and cannot be kneaded during cleaning. The connection between the frame and the filter net is not easy to handle, and after cleaning, it needs to be packaged in a bag or box to prevent dust. In addition, as an infrequently used tool part, in a kitchen where there are various small tools, there is often an embarrassing situation where the user forgets where to place it. Summary of the Utility Model

[0005] The purpose of the utility model is to provide a filter net structure for an open oil cup, detachably connecting the filter net with the cup cover of the oil cup, improving the convenience of storing and taking the filter net.

[0006] The technical solution of the utility model is as follows:

[0007] A filter screen structure for an open oil cup, comprising a cup body, a filter screen frame and a cup cover. The filter screen frame is cylindrical, the diameter of the filter screen frame is less than or equal to the inner diameter of the cup body. There is a flanging at the upper end of the filter screen frame, and a filter screen is provided in the middle of the lower end of the filter screen frame. The outer diameter of the flanging is greater than the inner diameter of the cup body. The cup cover is a cylindrical structure with an open lower end. There are at least three elastic clamping protrusions provided on the inner wall of the cup cover. The plurality of elastic clamping protrusions are located on the same virtual circumference. The diameter of the virtual circle is D1, the inner diameter of the cup cover is D2, the outer diameter of the flanging of the filter screen frame is D3, and the height of the elastic clamping protrusion protruding from the inner wall of the cup cover is D4. D1 < D3, (D2 - D3) < D4.

[0008] The depth of the cylindrical filter screen frame is relatively shallow, about 1 / 4 - 1 / 8 of the depth of the cup body. The diameter of the filter screen frame is the diameter of the barrel wall of the filter screen frame. The diameter of the filter screen frame is less than or equal to the inner diameter of the cup body, so that the lower part of the filter screen frame can extend into the cup body. D1 < D3. The flanging of the filter screen frame can support the filter screen frame at the port of the cup body, so as to carry out the filtering operation of edible oil.

[0009] Specifically, the plurality of elastic clamping protrusions are located on the same virtual plane parallel to the upper side of the cup cover, and the distance from this virtual plane to the cup cover is matched with the height of the flanging of the filter screen frame in the axial direction of the filter screen frame. The cross-section of the elastic clamping protrusion is semi-circular, and the outer side surface of the flanging of the filter screen frame is a smooth arc surface. The elastic clamping protrusion can be compressed to a certain extent. When the filter screen frame is not in use, the filter screen frame is squeezed into the cup cover, and the elastic clamping protrusion deforms. (D2 - D3) < D4, so that the flanging of the filter screen frame enters and is clamped in the gap between the elastic clamping protrusion and the cup cover, thereby fixing the filter screen frame in the cup cover. The gap between the barrel wall of the filter screen frame and the inner wall of the cup cover allows the insertion of the port of the cup body, so as to ensure the cooperation between the cup cover and the cup body.

[0010] Preferably, D2 = D3.

[0011] When using the filter screen frame, just take out the filter screen frame from the cup cover.

[0012] In the way of taking out the filter screen frame from the cup cover, the filter screen frame can be pulled out of the cup cover manually, but in this way, the hand will contact the filter screen frame, so there is a risk of contaminating the filter screen frame.

[0013] Another optional way of taking out is as follows:

[0014] A handle is provided in the middle of the cup cover. The handle comprises a sliding rod. The sliding rod penetrates through the cup cover, and the two ends of the sliding rod are respectively connected with a handle cap outside the cup cover and a pressing plate inside the cup cover. The handle cap, the sliding rod and the pressing plate form an I-shaped wheel structure. There is a compression spring between the handle cap and the outer side surface of the cup cover.

[0015] The sliding rod is perpendicular to the upper side surface of the cup lid and can slide up and down and rotate relative to the cup lid circumferentially.

[0016] When the operation of taking out the filter mesh rack is not performed, under the action of the compression spring, the pressing plate abuts against the cup lid.

[0017] When taking out the filter mesh rack, only need to press down the handle cap, so that the pressing plate is pressed down, push the filter mesh rack, and eject the filter mesh rack.

[0018] Preferably, compression spring clamping grooves are respectively provided on the surfaces of the handle cap corresponding to the cup lid for fixing both ends of the compression spring, so that the compression spring maintains a coaxial state with the sliding rod.

[0019] Furthermore, a positioning protrusion is provided on the circumferential surface of the sliding rod, and a positioning notch cooperating with the positioning protrusion is provided on the sliding hole of the cup lid cooperating with the sliding rod.

[0020] Only when the positioning protrusion is aligned with the positioning notch can the sliding rod slide relative to the cup lid. The setting of the positioning protrusion and the positioning notch prevents the filter mesh rack from being accidentally ejected under non-intentional circumstances.

[0021] Preferably, a diversion port is provided at the opening of the cup body, a protruding portion cooperating with the diversion port is provided on the cup lid, the positioning notch faces the protruding portion, and an arrow mark is provided on the side of the handle cap away from the cup lid, and the direction of the arrow mark cooperates with the protruding direction of the positioning protrusion.

[0022] The diversion port is a conventional design on the cup body for guiding the edible oil when pouring oil, and the protruding portion on the cup lid is used to cover the diversion port. The protruding portion forms a direction indication on the cup lid. When the arrow mark on the handle cap is aligned with the diversion port, the positioning protrusion and the positioning notch correspond to each other. This design conveniently finds the alignment position of the positioning protrusion and the positioning notch, so as to conveniently perform the operation of taking out the filter mesh rack.

[0023] An annular limiting boss is provided in the middle of the sliding rod.

[0024] The length of the sliding rod of the handle should meet the requirement that when the handle is pressed down, the pressing plate can contact the bottom of the filter mesh rack. Under this requirement, when the pressing plate is abutted against the lower side surface of the cup lid, the distance between the handle cap and the cup lid is too large and not convenient for use. The limiting boss is used to adjust the distance between the handle cap and the cup lid and meet the requirement that the pressing plate can touch the bottom of the filter mesh rack.

[0025] The filter mesh is a filter mesh woven by stainless steel wires.

[0026] In addition to being able to withstand the high temperature of the edible oil, the stainless steel filter mesh has high toughness and hardness, can withstand the pressure of the pressing plate, and prevents the filter mesh from being worn due to the long-term pressing of the pressing plate.

[0027] Specifically, the elastic snap protrusion is made of nitrile rubber.

[0028] Specifically, the depth of the filter mesh frame is less than the depth of the cup lid. This setting ensures that when the cup lid is placed on a tabletop, the filter mesh frame will not come into contact with the tabletop, reducing the probability of contamination of the filter mesh frame.

[0029] The advantages and positive effects of the present utility model are as follows: By adopting the above technical solution, when the filter mesh is not in use, the filter mesh can be stably fixed to the cup lid, avoiding the need for storage of the filter mesh. When the filter mesh is in use, the filter mesh can be conveniently removed. BRIEF DESCRIPTION OF THE DRAWINGS

[0044] As Figures 1-6 shown, the present utility model:

[0045] A filter screen structure for an open oil cup, comprising a cup body 1, a filter screen frame 2 and a cup cover 3. The filter screen frame 2 is cylindrical. The diameter of the cylindrical wall 21 of the filter screen frame is less than or equal to the inner diameter of the cup body 1. The upper end of the filter screen frame 2 is provided with a flanging 22. The middle of the lower end of the filter screen frame 2 is provided with a filter screen 23. The outer diameter of the flanging 22 is greater than the inner diameter of the cup body 1. The cup cover 3 is a cylindrical structure with an open lower end. There are at least three elastic clamping protrusions 31 on the inner wall of the cup cover. The plurality of elastic clamping protrusions 31 are located on the same virtual circumference. The diameter of the virtual circle is D1, the inner diameter of the cup cover 3 is D2, the outer diameter of the flanging of the filter screen frame is D3, and the height of the elastic clamping protrusion protruding from the inner wall of the cup cover is D4. D1 < D3, (D2 - D3) < D4.

[0046] The depth of the cylindrical filter screen frame 2 is relatively shallow, about 1 / 4 - 1 / 8 of the depth of the cup body 1. The diameter of the cylindrical wall 21 of the filter screen frame is less than or equal to the inner diameter of the cup body 1, so that the lower part of the filter screen frame 2 can extend into the cup body 1. D1 < D3, and the flanging 22 of the filter screen frame can support the filter screen frame 2 at the port of the cup body 1, so as to perform the filtering operation of edible oil.

[0047] Specifically, the plurality of elastic clamping protrusions 31 are located on the same virtual plane parallel to the upper side of the cup cover 3. The distance from this virtual plane to the cup cover is matched with the height of the flanging of the filter screen frame in the axial direction of the filter screen frame. The cross-section of the elastic clamping protrusion 31 is semi-circular, and the outer side surface of the flanging 22 of the filter screen frame is a smooth arc surface. The elastic clamping protrusion 31 can be compressed to a certain extent. When the filter screen frame 2 is not in use, the filter screen frame 2 is squeezed into the cup cover 3. Under the extrusion of the flanging 22, the elastic clamping protrusion 31 deforms. (D2 - D3) < D4, so that the flanging 22 of the filter screen frame enters and is clamped in the gap between the elastic clamping protrusion 31 and the cup cover 3, thereby fixing the filter screen frame 2 in the cup cover 3. The gap between the cylindrical wall 21 of the filter screen frame and the inner wall of the cup cover 3 allows the insertion of the port of the cup body 1, thereby ensuring the cooperation between the cup cover 3 and the cup body 1.

[0048] Preferably, D2 = D3.

[0049] When using the filter screen frame, just take out the filter screen frame from the cup cover.

[0050] The taking-out method is as follows:

[0051] A handle 4 is provided in the middle of the cup cover 3. The handle includes a sliding rod 41. The sliding rod penetrates through the cup cover 3. The two ends of the sliding rod 41 are respectively connected to a handle cap 42 outside the cup cover 3 and a pressing plate 43 inside the cup cover. The handle cap 42, the sliding rod 41 and the pressing plate 43 form an I-shaped wheel structure. A compression spring 44 is provided between the handle cap 42 and the outer side surface of the cup cover 3.

[0052] The sliding rod 41 is perpendicular to the upper side surface of the cup lid 3 and can slide up and down and rotate relative to the cup lid 3 circumferentially.

[0053] Preferably, compression spring clamping grooves 5 are respectively provided on the surfaces of the handle cap corresponding to the cup lid, for fixing both ends of the compression spring 44 and keeping the compression spring 44 coaxial with the sliding rod 41.

[0054] Furthermore, a positioning protrusion 45 is provided on the circumferential surface of the sliding rod 41, and a positioning notch 32 that mates with the positioning protrusion 45 is provided on the sliding hole of the cup lid 3 that mates with the sliding rod.

[0055] Only when the positioning protrusion 45 is aligned with the positioning notch 32 can the sliding rod slide relative to the cup lid 3. The setting of the positioning protrusion 45 and the positioning notch 32 prevents the filter screen holder 2 from being accidentally pushed out under non-intentional circumstances.

[0056] Preferably, a diversion port 11 is provided at the opening of the cup body, a protruding portion 33 that mates with the diversion port is provided on the cup lid, the positioning notch 32 faces the protruding portion 33, and an arrow mark 46 is provided on the side of the handle cap away from the cup lid, and the direction of the arrow mark matches the protruding direction of the positioning protrusion 45.

[0057] The diversion port is a conventional design on the cup body, for guiding the edible oil during oil pouring. The protruding portion on the cup lid is used to cover the diversion port. The protruding portion forms a direction indication on the cup lid. When the arrow mark on the handle cap is aligned with the diversion port, the positioning protrusion and the positioning notch correspond to each other. This design conveniently finds the alignment position of the positioning protrusion and the positioning notch, thus facilitating the operation of removing the filter screen holder.

[0058] An annular limiting convex platform 47 is provided in the middle of the sliding rod.

[0059] The length of the sliding rod of the handle should meet the requirement that when the handle is pressed down, the pressing plate can contact the bottom of the filter screen holder. Under this requirement, when the pressing plate is abutted against the lower side surface of the cup lid, the distance between the handle cap and the cup lid is too large and not convenient for use. The limiting convex platform is used to adjust the distance between the handle cap 42 and the cup lid 2 and meet the requirement that the pressing plate 43 can touch the bottom of the filter screen holder 1.

[0060] The filter screen is a filter screen woven from stainless steel wires.

[0061] In addition to being able to withstand the high temperature of edible oil, the stainless steel filter screen has high toughness and hardness, can withstand the pressure of the pressing plate, and prevents wear of the filter screen caused by the long-term pressing of the pressing plate.

[0062] Specifically, the elastic clamping protrusion is made of nitrile rubber.

[0063] Specifically, the depth of the filter mesh frame is less than that of the cup lid. This setting ensures that when the cup lid is placed on a tabletop, the filter mesh frame will not come into contact with the tabletop, reducing the probability of contamination of the filter mesh frame.

[0064] The working process of this embodiment is as follows:

[0065] When the filter mesh frame 2 is not in use, the filter mesh frame 2 is squeezed into the cup lid 3. Under the squeezing of the flanging 22, the elastic snap protrusion 31 deforms, allowing the flanging 22 of the filter mesh frame to enter and be clamped in the gap between the elastic snap protrusion 31 and the cup lid 3, thereby fixing the filter mesh frame 2 inside the cup lid 3. Then, the arrow mark 46 of the handle cap is pointed to a position other than the protruding part 33, so that the handle cannot be pressed down.

[0066] When taking out the filter mesh frame for filtering, first point the arrow of the handle cap 42 to the protruding part 33 so that the positioning protrusion 45 corresponds to the positioning notch 32. Press down the handle cap to press down the pressing plate 43 and push the filter mesh frame 2 to eject the filter mesh frame.

[0067] The above has described in detail an embodiment of the present invention, but the content described is only a preferred embodiment of the present invention and cannot be considered as limiting the scope of implementation of the present invention. All equivalent changes and improvements made within the scope of the application of the present invention should still fall within the scope covered by the patent of the present invention.
