Description

Technical Field

[0001] This utility model relates to the field of stirring cup technology, specifically a stirring cup that is resistant to plastic microparticles. Background Technology

[0002] A mixing cup is a convenient tool that mixes liquids and solids mechanically or automatically. Its core function is to improve mixing efficiency and reduce manual operation. It is widely used in beverage preparation, food pretreatment, and other scenarios. Depending on the driving method, it can be divided into manual mixing cups and automatic mixing cups. Among them, manual mixing cups are favored by users because of their simple structure and low manufacturing cost.

[0003] Currently, all existing manual stirring cups have a stirring lever with a rotating handle at the top and a stationary turbine blade at the bottom. The lever is threaded, and the cup lid has a hole in the center to accommodate the lever's threads. When the handle is lifted or pressed, it moves the lever through the hole in the lid, causing the lever's threads to rotate within the handle's recess. This, in turn, drives the turbine blade to rotate synchronously, stirring the liquid. These types of manual stirring cups all have the following problems: during stirring, the collision and friction between the lever and the lid can release microplastic particles into the liquid. The rotation and friction between the lever and the handle also release microplastic particles, especially when used to prepare formula for infants, which can lead to the infant ingesting large amounts of these particles, posing a significant health risk. To address this issue, the inventor has designed a microplastic-proof stirring cup. Utility Model Content

[0004] The purpose of this utility model is to provide a stirring cup that prevents the generation of plastic microparticles. It has the advantages of simple structure, reasonable design, and effective prevention of plastic microparticle generation by setting a collar at the stirring port and integrally molding the pull rod and handle. It is also easy to clean and solves the problems mentioned in the above technical background.

[0005] To achieve the above objectives, this utility model provides the following technical solution: a stirring cup that prevents plastic microparticles, comprising a cup body, a cup lid, and a stirring mechanism. The cup body is a hollow cavity structure with an opening at the top. The cup lid covers the opening of the cup body and can open or close the opening. A water outlet and a stirring port are provided on the cup lid. A collar is provided at the stirring port. The stirring mechanism includes a pull rod and a handle integrally formed on one end of the pull rod. The end of the pull rod away from the handle extends from the outside to the inside through the collar and into the cup body, and is detachably connected to a blade turbine inside the cup body. A water leakage hole is provided on the blade turbine. The pull rod can move back and forth within the collar under the action of external force, and move the blade turbine accordingly.

[0006] Preferably, the opening of the cup body is provided with external threads.

[0007] Preferably, the cup lid is provided with a handle and an internal thread that matches the external thread. The cup lid is also provided with a mounting groove in which a silicone ring is installed. When the cup lid is placed on the cup body, the silicone ring is pressed against the opening of the cup body to form a seal.

[0008] Preferably, the height of the water outlet is greater than the height of the stirring port, and the water outlet cover is provided with a silicone plug.

[0009] Preferably, the collar is made of silicone material and includes a collar body. The collar body is provided with a tightening part that matches the stirring port, and a through hole is provided on the collar body along its length direction for the pull rod to move back and forth.

[0012] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0013] 1. This utility model provides a stirring cup that prevents microplastic particles. The stirring cup includes a cup body, a cup lid, and a stirring mechanism. The cup body is a hollow cavity structure with an opening at the top. The cup lid is placed over the opening of the cup body and can be opened or closed. The cup lid has a water outlet and a stirring port. A collar is provided at the stirring port. The stirring mechanism is located inside the cup body. The overall structure is simple and reasonably designed. The stirring mechanism includes a pull rod and a handle integrally formed at one end of the pull rod. The pull rod and the handle are designed as one piece, eliminating relative rotation or friction, thus avoiding the pull rod and handle from rotating together. The plastic microparticles caused by friction between the hands are eliminated. The end of the lever away from the handle extends from the outside to the inside of the cup body through the collar and is detachably connected to the blade turbine inside the cup body. A drainage hole is opened on the blade turbine. By setting the collar, the lever does not directly contact the cup lid. When the lever moves up and down, there is no plastic microparticles generated due to collision and friction between the lever and the cup lid. During stirring, by pulling the lever up and down, the lever drives the blade turbine to move up and down. When the blade turbine comes into contact with and squeezes the liquid to be stirred in the cup body, the liquid to be stirred will leak out from the drainage hole, thus achieving the purpose of stirring.

[0014] 2. The pull rod in this utility model has a circular cross-section and is provided with a plug-in part for connecting with the blade turbine. The plug-in part is flat and has a U-shaped groove. An anti-disengagement buckle is provided at the opening of the groove. The circular pull rod is used to facilitate the up and down movement of the pull rod. When the plug-in part of the pull rod is plugged into the blade turbine, it can be limited by the anti-disengagement buckle. In order to facilitate the quick plugging and unplugging of the blade turbine, the anti-disengagement buckle is designed in the shape of a right trapezoid to achieve the purpose of quick assembly. When the blade turbine needs to be removed for cleaning, press the groove firmly to make the anti-disengagement buckle disengage from the blade turbine, so as to achieve the purpose of quick disassembly and cleaning.

[0015] 3. The collar in this utility model is made of silicone material and includes a collar body. A tightening part matching the stirring port is provided on the collar body, and a through hole for the pull rod to move back and forth is provided on the collar body along its length direction. A groove is provided on the inner wall of the through hole. When the liquid in the cup is poured out from the outlet, air can enter the cup through the groove so that the liquid is poured out more smoothly, which is highly practical.

[0027] Please see Figure 1 The present invention provides an embodiment of a stirring cup that prevents plastic microparticles. The stirring cup includes a cup body 1, a cup lid 2, and a stirring mechanism 3. The cup body 1 is a cavity structure with an opening at the top and a hollow interior. The cup lid 2 is placed over the opening of the cup body 1 and can open or close the opening. The stirring mechanism 3 is disposed inside the cup body 1 and can stir the liquid inside the cup body 1.

[0028] Please see Figure 2 and Figure 3The cup body 1 has an external thread 11 at its opening, and the cup lid 2 has a water outlet 21 and a stirring port 22. The stirring port 22 has a collar 23. In this embodiment, the collar 23 is made of silicone material. The cup lid 2 has an internal thread 25 that matches the external thread 11, and the cup lid 2 also has an installation groove 26. A silicone ring 27 is installed in the installation groove 26. When the cup lid 2 is placed on the cup body 1, the internal thread 25 is threadedly connected to the external thread 11, and the silicone ring 27 is pressed against the opening of the cup body 1 to form a seal. The cup lid 2 has a handle 24.

[0029] Specifically, the height of the outlet 21 is greater than the height of the stirring port 22, and the outlet 21 is covered with a silicone plug 28. In the design, the stirring port 22 is close to the handle 24. The purpose of this design is to prevent the liquid from flowing out of the stirring port 22 when the liquid in the cup body 1 is poured out from the outlet 21.

[0030] Please see Figure 4 The collar 23 in the figure includes a collar body 231. The collar body 231 is provided with a tightening part 232 that matches the stirring port 22. The collar body 231 has a through hole 233 along its length for the pull rod 31 to move back and forth. A groove 234 is formed on the inner wall of the through hole 233. When the liquid in the cup body 1 is poured out from the outlet 21, air can enter the cup body 1 through the groove 234 to make the liquid pouring out more smoothly, which is highly practical.

[0031] Please see Figure 5 and Figure 6 The stirring mechanism 3 includes a pull rod 31 and a handle 32 integrally formed on one end of the pull rod 31. The end of the pull rod 31 away from the handle 32 extends from the outside to the inside through the collar 23 and into the cup body 1, and is detachably connected to the blade turbine 33 inside the cup body 1. The blade turbine 33 is provided with a drain hole 34. The pull rod 31 can move back and forth in the collar 23 under the action of external force, and move the blade turbine 33. When the blade turbine 33 comes into contact with and is squeezed by the liquid to be stirred in the cup body 1, the liquid to be stirred will leak out from the drain hole 34. In this embodiment, multiple drain holes 34 are provided, and the multiple drain holes 34 are evenly distributed on the blade turbine 33. Each drain hole 34 gradually increases in size from one end to the other end, so that the liquid to be stirred will leak out from the drain hole 34 in a vortex shape, thereby achieving the stirring purpose.

[0032] Specifically, the pull rod 31 has a circular cross-section and is provided with a plug-in part 35 for connecting to the blade turbine 33. The plug-in part 35 is flat and has a U-shaped groove 36. An anti-detachment buckle 37 is provided at the opening of the groove 36. The anti-detachment buckle 37 is in the shape of a right trapezoid. When the plug-in part 35 of the pull rod 31 is plugged into the blade turbine 33, it can be limited by the anti-detachment buckle 37. In order to facilitate the quick plugging and unplugging of the blade turbine 33, the anti-detachment buckle 37 is designed in the shape of a right trapezoid to achieve the purpose of quick assembly. When it is necessary to remove the blade turbine 33 for cleaning, press the groove 36 firmly to make the anti-detachment buckle 37 disengage from the blade turbine 33, so as to achieve the purpose of quick disassembly and cleaning.
