Description

Technical Field

[0001] This application relates to the field of food processing, and more particularly to a cup lid, a blending cup assembly, and a food processor. Background Technology

[0002] With the continuous improvement of people's living standards, many different types of food processors have appeared on the market. The functions of food processors mainly include, but are not limited to, making soy milk, juicing, rice paste, mincing meat, shaved ice, making coffee, and / or preparing face masks. Food processors can include soy milk makers, blenders, or high-speed blenders—machines that pulverize and mix food. Existing food processors typically have vents on their lids. During use, food particles may overflow from these vents, contaminating the food processor and the countertop, making them difficult to clean. Utility Model Content

[0003] This application provides a cup lid, a blending cup assembly, and a food processor to at least solve some of the technical problems in the prior art.

[0004] This application provides a cup lid, comprising:

[0005] The cup lid body has a top surface that is recessed downward along the height direction of the cup lid body to form a receiving groove. The cup lid body is provided with a vent hole, which is located at the edge of the receiving groove and communicates with the receiving groove. The height of the side wall of the vent hole near the receiving groove is lower than the height of the side wall of the vent hole away from the receiving groove.

[0006] During the use of a food processor, food particles may overflow from the vent, contaminating the processor and the countertop, making them difficult to clean. To address this, the top surface of the lid is recessed downwards along its height to form a receiving groove. The vent is located at the edge of this groove and is connected to it. This groove collects and stores any food particles that overflow from the vent, preventing them from spilling onto the lid and causing damage to surrounding objects.

[0007] By making the sidewall height of the vent closer to the receiving tank lower than the sidewall height of the vent further away from the receiving tank, this height difference in the vent design ensures that the food slurry discharged from the vent flows smoothly into the receiving tank. This height difference in the vent design also helps control the flow path of the discharged material, preventing the food slurry from overflowing the receiving tank due to excessively fast or unstable flow rates.

[0008] Optionally, the outer wall of the receiving groove slopes upwards from the bottom towards the center away from the lid body; at least a portion of the vent is located on the outer wall of the receiving groove. Thus, the receiving groove is flared outwards, with the top area larger than the bottom area, facilitating cleaning of the interior. The fact that at least a portion of the vent is located on the outer wall of the receiving groove ensures that the food slurry discharged from the vent does not stagnate above or around the vent, but flows downwards along the outer wall, improving the efficiency and effectiveness of food slurry collection.

[0009] Optionally, the bottom surface of the receiving groove is a concave arc surface, and the lowest sidewall of the vent is not lower than the lowest point of the bottom surface of the receiving groove, while the bottom end of the vent is lower than the lowest point of the bottom surface of the receiving groove. In this way, the receiving groove with a concave arc surface at the bottom can provide more space to accommodate the food paste discharged from the vent. The vent is located at the top of the lowest sidewall inside the receiving groove, not lower than the lowest point of the bottom surface of the receiving groove. This ensures that the receiving groove can store food paste and prevents small amounts of food paste from flowing back into the cup through the vent, thus contaminating the food inside the cup. Furthermore, when a large amount of food paste enters the receiving groove, exceeding the height of the side of the vent closest to the receiving groove, it will flow back into the cup through the vent, preventing the food paste from overflowing the cup lid.

[0010] Optionally, the opening area of ​​the vent hole increases from bottom to top along the height direction of the cup lid body. This reduces the velocity of the food paste when it is discharged from the vent hole, preventing splashing and ensuring that the receiving tank can accommodate and collect it.

[0011] Optionally, the wall of the vent hole is inclined from bottom to top and from inside to outside along the height direction of the cup lid body. In this way, the opening area of ​​the vent hole gradually increases from bottom to top, which can reduce the speed at which food paste is discharged from the vent hole, avoid splashing, and ensure that the receiving tank can accommodate and collect it.

[0012] Optionally, the lid also includes a lid handle, disposed on the lid body, with the receiving groove surrounding and connected to the lid handle. Thus, by providing a lid handle, users can easily open the lid by gripping it. Furthermore, by having the receiving groove surround and connect to the lid handle, the height of the lid can be reduced, further reducing the height of the blending cup assembly and the food processor.

[0013] Optionally, the cup lid handle includes a first sidewall near the vent and a second sidewall away from the vent; both the first and second sidewalls are vertical planes along the height direction of the cup lid handle. This vertical plane makes it difficult to grip, thus preventing users from gripping the first sidewall near the vent and the second sidewall away from the vent, and avoiding burns from the hot air emitted from the vent.

[0014] The first sidewall is sloped, and the slope is inclined from bottom to top away from the vent hole along the height direction of the cup lid handle. This makes the first sidewall difficult to grip, thereby preventing the user from gripping the first sidewall of the cup lid handle near the vent hole and avoiding burns from the hot air emitted from the vent hole.

[0015] Optionally, the cup lid also includes a waterproof layer covering the connection between the cup lid handle and the cup lid body. Thus, when food paste or air bubbles are collected in the receiving slot, the waterproof layer prevents these substances from entering the space between the cup lid handle and the cup lid body, eliminating the need to clean this space and further reducing cleaning difficulty. It also prevents the space between the cup lid handle and the cup lid body from being neglected and allowing bacteria to grow there.

[0016] Optionally, the cup lid body is provided with a connecting post, and the cup lid handle is provided with a connecting hole that mates with the connecting post. The connecting post is detachably connected to the connecting hole. This facilitates the detachable connection between the cup lid handle and the receiving slot, and makes it easy to clean the space between the receiving slot and the cup lid handle.

[0017] Optionally, the cup lid body is provided with an upwardly protruding limiting rib, which is located around the connecting post. The inner wall of the bottom of the cup lid handle abuts against the outer wall of the limiting rib, and the waterproof layer covers the connection between the limiting rib and the cup lid handle. Thus, by providing the limiting rib, the inner wall of the bottom of the cup lid handle abuts against the outer wall of the limiting rib, preventing the cup lid handle from shaking within the receiving groove and improving the structural stability of the cup lid. Furthermore, the limiting rib also acts as a waterproof ring, preventing food slurry or air bubbles from entering the space between the cup lid handle and the cup lid body. The waterproof layer covering the connection between the limiting rib and the cup lid handle is equivalent to the first line of defense against food slurry or air bubbles entering the space between the cup lid handle and the cup lid body, while the limiting rib is equivalent to the second line of defense. The limiting rib and the waterproof layer work together to prevent food slurry or air bubbles in the receiving groove from contaminating the interior of the cup lid.

[0018] This application also provides a mixing cup assembly, including:

[0019] Cup body;

[0020] A cup lid that fits onto the cup body.

[0021] Because the mixing cup assembly has the lid described above, the height difference of the vent holes on the lid and the setting of the receiving slot ensure that the food paste discharged from the vent holes flows smoothly into the receiving slot. The receiving slot collects and stores the food paste that overflows from the vent holes, preventing the food paste that overflows from the vent holes from spilling out of the lid, making it difficult to clean, and preventing damage to surrounding objects.

[0022] This application also provides a food processor, including a blending cup assembly;

[0023] The base includes a base and a support extending upward from the base, the stirring cup assembly being assembled to the base;

[0024] The lid is assembled on the support base and is positioned above the cup lid.

[0025] This food processor can at least achieve the technical effect of the aforementioned cup lid.

[0026] Because the food processor has the lid mentioned above, the height difference of the vent holes on the lid and the setting of the receiving slot ensure that the food paste overflowing from the vent holes flows smoothly into the receiving slot. The receiving slot collects and stores the food paste overflowing from the vent holes, preventing the food paste overflowing from the vent holes from overflowing onto the lid, making it difficult to clean, and preventing damage to surrounding objects.

Detailed Implementation

[0033] Exemplary embodiments will now be described in detail, examples of which are illustrated in the accompanying drawings. When the following description relates to the drawings, unless otherwise indicated, the same numerals in different drawings denote the same or similar elements. The embodiments described in the following exemplary embodiments do not represent all embodiments consistent with this application. Rather, they are merely examples of apparatuses consistent with some aspects of this application as detailed in the appended claims.

[0034] Please refer to Figure 1 and Figure 2 , Figure 1 This is a perspective view of a cup lid 1 according to an embodiment of this application; Figure 2 for Figure 1 The cross-sectional view of the cup lid 1 shown. (As shown) Figure 1 and Figure 2 As shown, the cup lid 1 includes:

[0035] The cup lid body 10 has a recessed top surface along its height to form a receiving groove 11. The cup lid body 10 has a vent 12 located at the edge of the receiving groove 11 and communicating with it. The vent 12 is located on the side wall near the receiving groove 11. Figure 2 The height of the right side wall shown is lower than that of the side wall on the side of the vent 12 furthest from the receiving groove 11. Figure 2 The height shown is the height of the left side wall.

[0036] By providing an exhaust vent 12 on the cup lid body 10, the exhaust vent 12 can release the gas and pressure generated by the food being crushed by the high-speed rotating blades, preventing the cup lid 1 from being pushed open or broken due to excessive pressure.

[0037] During the use of the blender 100, food paste may overflow from the vent 12, contaminating the blender 100 and the countertop where it is placed, making it difficult to clean. This is especially true when the blender 100 malfunctions or is used improperly. The overflowing food paste from the vent 12 will spill onto the lid 1, contaminating the blender 100 and its surroundings, and potentially damaging nearby items. Furthermore, the spilled food paste is difficult to clean once it has overflowed from the vent 12.

[0038] This patent application describes a method to collect and store food slurry that overflows from the vent hole 12. The vent hole 12 is located at the edge of the vent hole 11 and communicates with it. The vent hole 11 collects and stores food slurry that overflows from the vent hole 12, preventing it from spilling out of the vent hole 12, making the vent hole 11 easier to clean, and avoiding damage to surrounding objects.

[0039] By making the height of the sidewall of the vent 12 closer to the receiving tank 11 lower than the height of the sidewall of the vent 12 farther from the receiving tank 11, the height difference of the vent 12 ensures that the food slurry discharged from the vent 12 flows smoothly into the receiving tank 11. The height difference of the vent 12 also helps to control the flow path of the discharged material, preventing the food slurry from overflowing outside the receiving tank 11 due to excessively fast or unstable flow.

[0040] like Figure 1 and Figure 2 As shown, the outer wall 111 of the receiving groove 11 slopes upwards from the bottom along the height direction of the cup lid body 10, away from the center of the cup lid body 10. The receiving groove 11 is outwardly flared, and the area of ​​the top of the receiving groove 11 is larger than the area of ​​the bottom of the receiving groove 11, which facilitates cleaning of the inside of the receiving groove 11.

[0041] At least a portion of the vent 12 is located on the outer wall 111 of the receiving tank 11, so that the food slurry discharged from the vent 12 can flow downward along the outer wall 111 of the receiving tank 11, thereby improving the efficiency and effectiveness of food slurry collection.

[0042] The vent 12 also has an inclined cross-section. By setting the outer wall 111 of the receiving groove 11 as an inclined surface, the top of the receiving groove 11 can be connected to the side of the vent 12 away from the receiving groove 11, and the bottom of the receiving groove 11 can be connected to the side of the vent 12 close to the receiving groove 11. The inclined cross-section of the vent 12 and the outer wall 111 of the receiving groove 11 connect smoothly, enhancing the aesthetics of the cup lid 1. Figure 2In the embodiment shown, the angle α between the outer wall 111 of the receiving groove 11 and the height direction of the cup lid body 10 ranges from 45° to 65°.

[0043] Please refer to Figure 2 The bottom surface of the receiving groove 11 is a concave arc surface, and the lowest sidewall of the vent hole 12 is not lower than the lowest position of the bottom surface of the receiving groove 11, while the bottom end of the vent hole 12 is lower than the lowest position of the bottom surface of the receiving groove 11. For example... Figure 2 As shown, the lowest position of the side wall of the exhaust hole 12 is A, the lowest position of the bottom surface of the receiving groove 11 is B, and the bottom position of the exhaust hole 12 is C. The position of A is not lower than the position of B, and the position of C is lower than the position of B.

[0044] The recessed groove 11, with its concave arc bottom, provides more space to accommodate the food slurry discharged from the vent 12. Figure 2 In the embodiment shown, the distance L1 between the lowest point of the bottom surface of the receiving groove 11 and the top of the receiving groove 11 ranges from 7mm to 20mm.

[0045] The lowest sidewall of the vent 12 (A in the figure) is not lower than the lowest point of the bottom surface of the receiving tank 11 (B in the figure). Position A is not lower than position B. This ensures that the receiving tank 11 can store food slurry and prevents small amounts of food slurry from flowing back into the cup body 31 through the vent 12, thus contaminating the food in the cup body 31. Furthermore, when a large amount of food slurry enters the receiving tank 11, exceeding the height of the side of the vent 12 closest to the receiving tank 11, it will flow back into the cup body 31 through the vent 12, preventing the food slurry from overflowing the cup lid 1.

[0046] By making the bottom end of the vent hole 12 (C shown in the figure) lower than the lowest position of the bottom surface of the receiving tank 11 (B shown in the figure), and the position of C being lower than the position of B, it is convenient for the food paste to flow back into the cup body 31 through the vent hole 12 when a large amount of food paste enters the receiving tank 11, thus preventing the food paste from overflowing the cup lid 1.

[0047] like Figure 2 As shown, the opening area of ​​the vent 12 increases from bottom to top along the height direction of the cup lid body 10. This reduces the impact force of the food paste when it is discharged through the vent 12, preventing splashing.

[0048] Optionally, the wall of the vent 12 is inclined from bottom to top and from the inside to the outside along the height direction of the cup lid body 10. That is, as shown... Figure 1 and Figure 2As shown, the vent 12, located on the outer sidewall of the receiving groove 11, slopes upwards along the height direction of the lid body 10 towards the outside of the receiving groove 11. Conversely, the vent 12, located on the inner sidewall of the receiving groove 11, slopes upwards along the height direction of the lid body 10 towards the inside of the receiving groove 11. This design allows the opening area of ​​the vent 12 to gradually increase from bottom to top, reducing the impact force of the food paste when it is discharged through the vent 12 and preventing splashing. Figure 2 In the embodiment shown, the opening angle β of the exhaust port 12 ranges from 5° to 45°.

[0049] Please refer to Figure 3 , Figure 3 for Figure 1 The exploded view of cup lid 1 is shown. Figure 3 As shown, the lid 1 also includes a lid handle 20, which is disposed on the lid body 10. A receiving groove 11 is arranged around the lid handle 20 and connected to the lid handle 20. The height of the side wall of the vent 12 near the lid handle 20 is lower than the height of the side wall of the vent 12 away from the lid handle 20. Thus, by providing the lid handle 20, it is convenient for the user to open the lid 1 by gripping the lid handle 20. By arranging the receiving groove 11 around the lid handle 20 and connecting it to the lid handle 20, the height of the lid 1 can be reduced, further reducing the height of the blending cup assembly 3 and the food processor 100.

[0050] exist Figure 3 In the illustrated embodiment, the cup lid handle 20 includes a first sidewall 23 near the vent 12 and a second sidewall 24 away from the vent 12. Both the first sidewall 23 and the second sidewall 24 are vertical planes along the height direction of the cup lid handle 20. The vertical planes are not conducive to gripping, thus preventing users from gripping the first sidewall 23 near the vent 12 and the second sidewall 24 near the vent 12, and avoiding burns from the hot air emitted from the vent 12.

[0051] In other embodiments, the first sidewall 23 is inclined, and the inclined surface slopes from bottom to top away from the vent 12 along the height direction of the cup lid handle 20. This makes the first sidewall 23 of the cup lid handle 20 near the vent 12 difficult to grip, thereby preventing the user from gripping the first sidewall 23 of the cup lid handle 20 near the vent 12 and avoiding burns from the hot air discharged from the vent 12.

[0052] Please also refer to Figure 2The lid 1 also includes a waterproof layer 25, which covers the connection between the lid handle 20 and the lid body 10. Thus, when food paste or air bubbles are collected in the receiving slot 11, the waterproof layer 25 prevents these substances from entering the space between the lid handle 20 and the lid body 10, eliminating the need to clean this space and further reducing cleaning difficulty. It also prevents the space between the lid handle 20 and the lid body 10 from being neglected and allowing bacteria to grow there.

[0053] In this embodiment, the waterproof layer 25 covers not only the connection between the cup lid handle 20 and the cup lid body 10, but also the entire cup lid handle 20. Thus, the waterproof layer 25 has a relatively large coverage area, making it less likely to detach from the connection between the cup lid handle 20 and the cup lid body 10.

[0054] In some embodiments, the waterproof layer 25 also has a heat insulation function. The waterproof layer 25 can be made of silicone or soft rubber. Silicone or soft rubber has good elasticity and softness, providing a comfortable touch. Furthermore, silicone or soft rubber materials have good heat insulation properties, preventing the lid handle 20 from becoming too hot and avoiding burns to the hands from direct contact with the hot lid handle 20.

[0055] In this embodiment, the receiving groove 11 is located at the center of the top surface of the cup lid body 10, and the cup lid handle 20 is located at the center of the receiving groove 11. Thus, when the cup lid handle 20 is located on the cup lid body 10, the cup lid handle 20 is also located near the center of the cup lid body 10, resulting in an aesthetically pleasing design.

[0056] In this embodiment, the cup lid handle 20 also includes a handle top cover 22, which is connected to the top surface of the cup lid handle 20. This improves the aesthetics of the cup lid 1. A waterproof layer 25 covers the connection between the cup lid handle 20 and the handle top cover 22, preventing debris from entering the space between the cup lid handle 20 and the handle top cover 22.

[0057] In the embodiment shown in this application, the cup lid handle 20 is detachably connected to the cup lid body 10. This makes the cup lid handle 20 and the cup lid body 10 easy to assemble and reduces the processing difficulty of the cup lid 1.

[0058] like Figure 3 As shown, the cup lid body 10 is provided with a connecting post 13, and the cup lid handle 20 is provided with a connecting hole 21 that mates with the connecting post 13. The connecting post 13 is detachably connected to the connecting hole 21. Thus, the cup lid handle 20 and the cup lid body 10 are connected by the connecting post 13 and the connecting hole 21. The detachable connecting post 13 design allows the cup lid handle 20 to be easily removed from the cup lid body 10 for easy cleaning and maintenance.

[0059] The cup lid body 10 has an upwardly protruding limiting rib 14 located around the connecting post 13. The inner wall of the bottom of the cup lid handle 20 abuts against the outer wall of the limiting rib 14, and the waterproof layer 25 covers the connection between the limiting rib 14 and the handle of the cup body 31. Thus, by setting the limiting rib 14, the inner wall of the bottom of the cup lid handle 20 abuts against the outer wall of the limiting rib 14, preventing the cup lid handle 20 from shaking within the receiving groove 11 and improving the structural stability of the cup lid 1. Furthermore, the limiting rib 14 also acts as a waterproof ring, preventing food paste or air bubbles from entering the space between the cup lid handle 20 and the cup lid body 10. The waterproof layer 25 covers the connection between the limiting rib 14 and the handle of the cup body 31, acting as the first line of defense to prevent food slurry or air bubbles from entering the space between the cup lid handle 20 and the cup lid body 10. The limiting rib 14 acts as the second line of defense to prevent food slurry or air bubbles from entering the space between the cup lid handle 20 and the cup lid body 10. The limiting rib 14 and the waterproof layer 25 work together to prevent food slurry or air bubbles in the receiving groove 11 from contaminating the interior of the cup lid 1.

[0060] Please also refer to Figure 3 and Figure 2 The waterproof layer 25 covers the bottom of the contact point between the limiting rib 14 and the cup lid handle 20, thus preventing foreign objects from entering the gap between the limiting rib 14 and the cup lid handle 20 and making cleaning inconvenient.

[0061] The receiving groove 11 is also provided with at least one upwardly protruding first reinforcing rib 15, which connects the connecting post 13 and the limiting rib 14. This enhances the strength of the connecting post 13, thereby improving the stability of the cup lid 1. In this embodiment, there are two connecting posts 13, and the cup lid handle 20 has two connecting holes 21 that mate with the connecting posts 13. The receiving groove 11 is also provided with an upwardly protruding second reinforcing rib 16, which connects the two connecting posts 13.

[0062] In this embodiment, the cup lid 1 further includes a sealing ring 18, which is fitted onto the bottom of the cup lid body 10. The sealing ring 18 forms a seal between the cup lid body 10 and the cup body 31, preventing food from overflowing between them. When the cup lid 1 is fastened to the cup body 31, the sealing ring 18 is located below the spout of the cup body 31. This prevents food from overflowing from the spout and allows it to overflow only through the vent 12 into the receiving groove 11, where it is collected.

[0063] In this embodiment, a groove 17 is provided circumferentially at the bottom of the cup lid body 10, and a sealing ring 18 is disposed within the groove 17. Thus, the groove 17 can restrict the movement of the sealing ring 18 in the height direction of the cup lid body 10, further improving the sealing performance between the cup body 31 and the cup lid 1.

[0064] This application also provides a mixing cup assembly 3, including: a cup body 31 and a cup lid 1, the cup lid 1 being fitted onto the cup body 31. Please refer to... Figure 4 , Figure 4 This is a schematic diagram of the structure of the stirring cup assembly 3 according to one embodiment of this application. Figure 4 As shown, the mixing cup assembly 3 also includes a blade assembly 32, disposed inside the cup body 31, for stirring or crushing the contents of the cup body 31. In some embodiments, the bottom of the lid 1 is disposed inside the top of the cup body 31, and the cup body 31 and the lid 1 are snapped together or screwed on. This facilitates the lid 1 to close the cup body 31 or to be removed from the cup body 31.

[0065] This application also provides a food processor 100, including a mixing cup assembly 3. Please refer to... Figure 5 , Figure 5 This is a schematic diagram of the structure of a food processor 100 provided in one embodiment of this application, as shown below. Figure 5 As shown, the food processor 100 also includes a base 4 and a lid 5. The base 4 includes a base 41 and a support 42 extending upward from the base 41. The support 42 and the base 41 can be integrally formed or separately formed and then assembled together. The blending cup assembly 3 is assembled to the base 41, and the lid 5 is assembled to the support 42, with the lid 5 covering the blending cup assembly 317.

[0066] The above-mentioned limitations on the lid 1 and the effects achieved also apply to the mixing cup assembly 3 and the food processor 100, which will not be elaborated upon further in this application.

[0067] The above are merely preferred embodiments of this application and are not intended to limit this application. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this application should be included within the scope of protection of this application.
