Description

Technical Field

[0001] This utility model relates to the field of stirring cup technology, and in particular to a cup lid structure for a vacuum stirring cup. Background Technology

[0002] Maintaining the freshness and quality of food ingredients is a key challenge in food processing and storage. Many ingredients, especially those rich in nutrients or volatile flavor compounds (such as fruits, vegetables, and juices), are highly susceptible to oxidation or bacterial growth upon contact with air, leading to discoloration, flavor degradation, nutrient loss, and even spoilage. For example, in the case of fruit juice, exposure to oxygen in the air rapidly triggers oxidation, damaging its color, texture, and vitamin content, significantly reducing product quality. To effectively prevent the adverse effects of air on food ingredients, vacuum technology is widely used in food processing and storage.

[0003] In high-end food processors, vacuuming before blending ingredients has become a crucial step in enhancing the texture, color, and freshness of the finished product. However, existing vacuuming technology suffers from a significant drawback in practical applications: during the air extraction process, some liquid, slurry, or finely chopped ingredients (such as juice, puree, broth, powder, or foam) are easily entrained by the high-speed airflow, adsorbed, and accumulated in the suction port or connected pipes. This blockage not only rapidly reduces vacuuming efficiency and affects the final vacuum level but can also, in severe cases, cause the vacuuming function to fail, preventing the achievement of the expected freshness preservation and quality improvement effects. This has become a key bottleneck restricting the effective application of this technology. Utility Model Content

[0029] Example

[0030] Reference Figures 1 to 3 The present invention proposes a lid structure for a vacuum stirring cup, comprising a cup body 10 and a lid assembly; the lid assembly is detachably mounted on the cup body 10.

[0031] The cup lid assembly includes a cup lid body 20, an upper cup lid 30, and a negative pressure suction channel 40; the cup lid body 20 is provided with a vacuum suction chamber 21, and the upper cup lid 30 is detachably covered on the vacuum suction chamber 21; the vacuum suction chamber 21 has a number of fine holes 22 that communicate with the cup body 10.

[0032] The cup lid body 20 is provided with a recessed buffer cavity 23, which is recessed below the vacuum adsorption cavity 21; the air extraction hole 41 of the negative pressure suction channel 40 is located above the vacuum adsorption cavity 21 and at the bottom away from the recessed buffer cavity 23.

[0033] In this invention, the recessed buffer chamber 23 is located below the vacuum adsorption chamber 21, forming a gravity settling zone. During high-speed suction, liquid / slurry-like ingredients (such as juice or foam) carried by the airflow sink to the bottom of the recessed buffer chamber 23 due to their own weight, preventing them from being sucked into the suction port 41. The suction port 41 is located at the top of the vacuum adsorption chamber 21 and away from the bottom of the buffer chamber, physically isolating the food accumulation area from the airflow channel, blocking the risk of blockage at the source. The buffer chamber's retention effect on the food ensures that the suction port 41 remains unobstructed, ensuring that the airflow efficiency of the negative pressure suction channel 40 is not affected, allowing the vacuum level inside the cup to quickly reach and maintain an ideal level, effectively delaying the oxidation and spoilage of the food. The detachable design of the upper cup lid 30 allows direct cleaning of the vacuum adsorption chamber 21 and the recessed buffer chamber 23, thoroughly removing residual food and preventing bacterial growth and cross-contamination. The protected suction port 41 is less prone to clogging, reducing the failure rate and extending the service life of the vacuum device.

[0034] In this embodiment, the cup lid assembly is provided with a vertically extending suction column 24, and the suction column 24 is provided with an upwardly extending suction channel 42. The suction hole 41 forms a three-dimensional suction channel with the vertical suction column 24, forcing the airflow path to flow vertically from bottom to top, and further utilizing gravity to separate the food from the air. The upwardly extending suction channel 42 ensures that the suction hole 41 is always at the highest point of the airflow path, preventing the settled food from contacting the suction hole 41. The suction channel 42 is connected to the vacuum adsorption chamber 21 at one end.

[0035] Specifically, the top surface of the suction column 24 is positioned close to the upper cup lid 30. This design maximizes the height of the suction hole 41, increases its distance from the bottom of the buffer chamber, and enhances its anti-clogging reliability.

[0036] Preferably, the distance between the top surface of the suction column 24 and the upper cup lid 30 is between 1 mm and 4 mm. This precisely balances sealing performance and airflow efficiency, ensuring that the high-speed airflow only draws in gas while preventing liquid backflow due to surface tension.

[0037] Preferably, the diameter of the extraction port 41 is between 1 mm and 4 mm. This diameter range achieves a better balance between clogging prevention and extraction efficiency.

[0038] In this embodiment, the cup lid body 20 is provided with a stepped surface 25, which extends laterally to the top outer edge of the recessed buffer cavity 23; fine holes 22 are formed on the stepped surface 25. The stepped surface 25 extends laterally to the top outer edge of the buffer cavity, forming a physical barrier; the fine holes 22 are formed on the stepped surface 25, dispersing the air intake points and preventing excessive local negative pressure from drawing in liquid; the position is higher than the liquid surface of the buffer cavity, achieving the effect of gas passing through from above and residue falling off below.

[0039] In this embodiment, the upper lid 30 is provided with a pressure relief port 31, and the pressure relief port 31 is provided with a resilient pressure relief sealing plug 50. When breaking the vacuum to open the lid or taking out the contents of the mixing cup, press to release the pressure to avoid the airflow impact at the moment of opening the lid, which may cause the food to splash; the resilient seal ensures that it closes automatically when the vacuum is drawn, maintaining airtightness.

[0040] Specifically, the pressure relief sealing plug 50 includes a sealing post 51, an upper sealing cap 52, and a lower sealing cap 53. The sealing post 51 can be inserted into the pressure relief port 31, and the upper sealing cap 52 and lower sealing cap 53 can respectively fit and seal the upper and lower sides of the pressure relief port 31. Double sealing caps (upper / lower): The upper sealing cap 52 prevents external contamination from entering the pressure relief port 31; the lower sealing cap 53 prevents liquid from seeping into the channel. The sealing post 51 insertion structure provides precise guidance, ensuring that the sealing plug returns to its original position without shifting after pressing.

[0041] Furthermore, the upper side of the upper sealing cover 52 is also provided with a force application part 54 to increase the contact area of ​​the fingers and realize easy pressure release by pressing with one finger.

[0042] In this embodiment, the cup lid body 20 and the upper cup lid 30 are provided with a matching rotating locking structure 60, which enables quick assembly and disassembly of the cup lid body 20 and the upper cup lid 30, simplifying the cleaning steps; a sealing ring 70 is provided between the cup lid body 20 and the upper cup lid 30 to ensure the airtightness of each joint surface of the cup lid assembly and prevent vacuum leakage; the negative pressure suction channel 40 is provided with a one-way sealing valve 43, which opens when vacuuming and closes automatically when stopping.

[0043] Preferably, the upper cup lid 30 is made of transparent plastic or transparent rubber material, which makes it easy to see the inside of the vacuum adsorption chamber 21 and determine whether it needs to be cleaned in time.

[0044] Of course, this utility model is not limited to the above-described embodiments. Those skilled in the art can make equivalent modifications or substitutions without departing from the spirit of this utility model. All such equivalent modifications and substitutions are included within the scope defined by the claims of this application.
