Description

Technical Field

[0001] This utility model relates to the field of milk frother technology, and in particular to a stirring and frothing mechanism and a milk frother. Background Technology

[0002] With the popularization of coffee culture, the demand for home and commercial milk frothers is increasing. High-quality milk foam requires fine, uniform, and stable bubbles. To achieve this goal, existing milk frothers typically include a stirring component and a foaming component. The main function of the stirring component is to rotate at high speed driven by a motor, drawing air into the milk to form large bubbles. The foaming component, on the other hand, is used to break down the initially formed bubbles into finer bubbles, thereby obtaining a smooth and creamy milk foam.

[0003] However, existing products use a single integrated design for the mixing and stirring components. This approach has revealed significant drawbacks in practical use. On the one hand, because the structure is not disassembled, cleaning is difficult. On the other hand, if any component of the mixing or stirring component is damaged, the entire structure must be replaced, resulting in unnecessary waste of resources.

[0004] Therefore, improvements to existing technologies are necessary. Utility Model Content

[0005] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a stirring and frothing mechanism and a milk frother, which can solve the problems of difficult cleaning and high maintenance costs caused by the integrated design of the stirring and frothing components in existing milk frothers.

[0006] According to an embodiment of the present invention, a stirring and frothing mechanism includes a support member, a frothing member, and a stirring member. The support member is installed in the body of the milk frother. The frothing member is connected to the support member and is provided with a limiting part. The stirring member is detachably inserted into the limiting part and can rotate relative to the frothing member under the drive of an external force.

[0007] According to an embodiment of this utility model, a stirring and frothing mechanism has at least the following beneficial effects: In traditional milk frothers, the stirring and frothing components are integrated, making it difficult to thoroughly clean some small parts due to the narrow space and mutual interference. However, in this utility model's stirring and frothing mechanism, the stirring component is detachably inserted into the frothing component. During cleaning, the stirring component can be easily removed from the frothing component, and the separated stirring and frothing components can be meticulously processed separately, effectively removing hidden dirt. Furthermore, the detachable connection between the stirring and frothing components means that if one component is damaged, only the damaged component needs to be replaced, without replacing the entire mechanism. This significantly reduces the cost of component replacement and saves users maintenance expenses.

[0008] According to some embodiments of the present invention, the support member is provided with a threaded hole, and the cotton-pulling member is correspondingly provided with a connecting post, the connecting post being threadedly connected to the threaded hole.

[0009] According to some embodiments of the present invention, the support member includes a fixed column and an outer cover connected to the fixed column. The outer cover forms a hollow cavity, and a plurality of slots are provided on its peripheral wall. The threaded hole is opened in the fixed column, and the cotton-beating component and the stirring component are housed in the cavity of the outer cover.

[0010] According to some embodiments of the present invention, the stirring component further includes a plurality of blades, each blade being fixed at intervals to the circumferential outer side of the connecting column, the connecting column having the limiting portion, and the stirring component being detachably inserted into the limiting portion.

[0012] According to some embodiments of the present invention, the bottom of the inner cover extends outward with a plurality of limiting blocks, and each limiting block is arranged at intervals along the circumference; when the support member is installed in the body of the milk frother, the outer wall of each limiting block abuts against the inner wall of the milk frother body to restrict the movement of the support member in the horizontal direction.

[0013] According to some embodiments of the present invention, the stirring component includes a rotating shaft, a mounting frame, and a stirring plate. The first end of the rotating shaft is detachably inserted into the limiting part, the second end of the rotating shaft is connected to one end of the mounting frame, and the stirring plate is sleeved and fixed on the mounting frame.

[0014] According to some embodiments of the present invention, the stirring component further includes a base and a first magnetic suction component. The base is connected to the end of the mounting bracket away from the rotating shaft. A receiving cavity is formed in the base, and the first magnetic suction component is fixedly disposed in the receiving cavity.

[0015] According to some embodiments of this utility model, the stirring plate has an opening, and a filter screen is provided at the opening. When the stirring element rotates, it drives the liquid containing air bubbles to flow through the filter screen. The filter screen generates a shearing action on the flowing air bubbles to cut and break large air bubbles into medium-sized air bubbles.

[0024] Please refer to Figures 1-4 According to an embodiment of the present invention, a stirring and frothing mechanism includes a support member, a frothing member 11 and a stirring member 13. The support member is installed in the body of the milk frother. The frothing member 11 is connected to the support member and is provided with a limiting part 113. The stirring member 13 is detachably inserted into the limiting part 113 and can rotate relative to the frothing member 11 under the drive of an external force.

[0025] Traditional milk frothers have an integrated design of the agitator 13 and the frother 11. Due to limited space and mutual interference, some parts of the agitator 13 and frother 11 are difficult to clean thoroughly. However, in this invention, the agitator 13 is detachably inserted into the frother 11. During cleaning, the agitator 13 can be easily removed from the frother 11, and the separated agitator 13 and frother 11 can be cleaned separately. Furthermore, the detachable connection of the agitator 13 and frother 11 means that if one component is damaged, only the damaged component needs to be replaced, eliminating the need to replace the entire mechanism. This significantly reduces component replacement costs and saves users repair expenses.

[0026] According to some embodiments of the present invention, the support member has a threaded hole, and the cotton-padded member 11 is correspondingly provided with a connecting post 111, which is threadedly connected to the threaded hole.

[0027] When assembling the mixing and beating mechanism, align the connecting post 111 on the beating component 11 with the threaded hole on the support component, and then rotate the connecting post 111 to achieve thread engagement with the threaded hole, thereby fixing the beating component 11 to the support component. This threaded connection method is simple and reliable, ensuring the stability of the connection between the beating component 11 and the support component, while also facilitating disassembly and installation, and making subsequent maintenance and cleaning convenient.

[0028] According to some embodiments of the present invention, the support member includes a fixed column 10 and an outer cover 14 connected to the fixed column 10. The outer cover 14 forms a hollow cavity 16, and a plurality of slots 15 are provided on its peripheral wall. Threaded holes are provided in the fixed column 10. The cotton-beating member 11 and the stirring member 13 are housed in the cavity 16 of the outer cover 14.

[0029] The hollow chamber 16 of the outer cover 14 provides a relatively independent working space for the cotton-beating component 11 and the stirring component 13. The slots 15 on the peripheral wall can ensure that the liquid can smoothly enter the chamber 16 and come into contact with the cotton-beating component 11 and the stirring component 13, while also providing a certain degree of protection for the internal components and preventing external objects from interfering with their normal operation.

[0030] According to some embodiments of the present invention, the support member further includes an inner cover 17, and an annular groove 12 is formed between the fixing post 10 and the connecting post 111; the inner cover 17 is provided with a protrusion 18 and a through hole 20, the through hole 20 connects the slot 15 and the chamber 16, the protrusion 18 is accommodated and confined in the annular groove 12, and is interference-fitted with the fixing post 10 and the connecting post 111.

[0031] When assembling the support component, the protrusion 18 of the inner cover 17 is aligned with the annular groove 12 formed between the fixing post 10 and the connecting post 111. Then, by applying a certain pressure, the protrusion 18 and the annular groove 12 achieve an interference fit, thereby fixing the inner cover 17 to the support component. The inner cover 17 further enhances the structural stability of the support component, and the interference fit ensures the tightness of the connection between the inner cover 17 and the fixing post 10 and the connecting post 111, preventing loosening or detachment during operation.

[0032] Of course, it should be noted that the blades 112 of this utility model are inclined towards the slots 15 and through holes 20. When in use, the chocolate can be placed outside the outer cover 14, and the stirring element 13 rotates at high speed in the chamber 16, causing the hot milk inside to form a strong flow. The high-speed hot milk driven by the stirring element 13 impacts the blades 112 inclined towards the slots 15 and through holes 20. The blades 112 guide the hot milk towards the through holes 20 and slots 15. The hot milk comes into contact with the surface of the chocolate, and the chocolate gradually melts. The melted chocolate sauce mixes with the hot milk, and finally a cup of chocolate-flavored milk foam drink with a uniform texture is obtained.

[0033] According to some embodiments of the present invention, the bottom of the inner cover 17 extends outward with a plurality of limiting blocks 19, and each limiting block 19 is arranged at intervals along the circumference; when the support is installed in the body of the milk frother, the outer wall of each limiting block 19 abuts against the inner wall of the milk frother body to restrict the movement of the support in the horizontal direction.

[0034] When the support component is installed into the milk frother body, multiple limiting blocks 19 at the bottom of the inner cover 17 will contact the inner wall of the milk frother body. Since the limiting blocks 19 are arranged at intervals along the circumference, they will work together to prevent the support component from moving in the horizontal direction. The design of the limiting blocks 19 ensures that the support component is installed in an accurate and stable position within the milk frother body, avoiding the impact on the normal operation of the stirring and frothing mechanism due to the support component shaking during operation, and improving the overall operational stability of the milk frother.

[0035] According to some embodiments of the present invention, the stirring component 13 includes a rotating shaft 131, a mounting frame 132, and a stirring plate 133. The first end of the rotating shaft 131 is detachably inserted into the limiting part 113, the second end of the rotating shaft 131 is connected to one end of the mounting frame 132, and the stirring plate 133 is sleeved and fixed on the mounting frame 132.

[0036] Since the first end of the rotating shaft 131 is detachably inserted into the limiting part 113 of the connecting column 111 of the cotton-beating component 11, the rotation of the rotating shaft 131 will drive the mounting bracket 132 to rotate together, thereby driving the stirring plate 133 sleeved on it to rotate, and the stirring plate 133 will stir the liquid.

[0037] According to some embodiments of the present invention, the stirring plate 133 has an opening, and a filter screen 134 is provided at the opening. When the stirring member 13 rotates, it drives the liquid containing air bubbles to flow through the filter screen 134. The filter screen 134 generates a shearing action on the flowing air bubbles to cut and break large air bubbles into medium-sized air bubbles.

[0038] According to some embodiments of the present invention, the cotton-beating component 11 further includes a plurality of blades 112, each blade 112 being fixed at intervals to the circumferential outer side of the connecting column 111, the connecting column 111 having a limiting part 113, and the stirring component 13 being detachably inserted into the limiting part 113.

[0039] Low-fat milk, due to its low fat content, often struggles to form stable, dense bubbles using traditional milk frothing methods. To address this issue, this invention incorporates a paddle 112 and a filter 134. The paddle 112 and filter 134 work synergistically, while the stirring element 13 rotates at high speed, generating vortices that draw air into the hot milk, creating a coarse cluster of large bubbles of varying sizes. Simultaneously, it acts like a pump, forcibly pushing this liquid containing large bubbles towards the filter 134. The filter 134 acts like a "cutter," pulverizing the bubbles as they are forced through the fine mesh, resulting in smaller, more uniform "intermediate bubbles." The liquid flow, after being cut by the filter 134, impacts the stationary paddle 112 at high speed and with complex flow directions, generating countless chaotic vortices and eddies of varying sizes. Each micro-vortex acts as a "grinding machine," subjecting the bubbles to irregular compression, stretching, and shearing from all directions. This "all-around, no-dead-angle" grinding effect is far more efficient than simple rotational shearing force, grinding bubbles into extremely fine particles and ensuring a high degree of uniformity in the final milk foam texture. Highly uniform, extremely small microbubbles are inherently more stable because the pressure difference inside small bubbles is smaller, making them less likely to coalesce into larger bubbles. This ideal bubble structure, created through physical means, compensates for the stability deficiency caused by the lack of fat globules as a "physical barrier" in low-fat milk, thus achieving the goal of producing high-quality, dense milk foam using low-fat milk.

[0040] According to some embodiments of the present invention, the stirring member 13 further includes a base 135 and a first magnetic member 136. The base 135 is connected to the end of the mounting frame 132 away from the rotating shaft 131. A receiving cavity 137 is formed in the base 135, and the first magnetic member 136 is fixedly disposed in the receiving cavity 137.

[0041] According to the present invention, a milk frother includes a base, a milk frother body, and a stirring and frothing mechanism. A motor is installed inside the base, and a second magnetic component is connected to the output end of the motor. The milk frother body is detachably installed on the base, and the stirring and frothing mechanism is detachably installed inside the milk frother body. The second magnetic component magnetically attracts the first magnetic component 136 in the stirring and frothing mechanism, thereby driving the filter screen 134 and the stirring plate 133 in the stirring and frothing mechanism to rotate.

[0042] In use, first install the milk frother onto the base, then install the stirring and frothing mechanism into the milk frother. Start the motor inside the base; the motor drives the second magnetic component to rotate. The second magnetic component, through magnetic attraction, drives the first magnetic component 136 in the stirring and frothing mechanism to rotate, thereby activating the stirring component 13 and the frothing component 11 to stir and froth the liquid inside the milk frother. Using magnetic attraction to transmit power avoids the wear and noise problems that may exist in traditional mechanical transmission methods, improving the working stability and service life of the milk frother.

[0043] The embodiments of the present utility model have been described in detail above with reference to the accompanying drawings. However, the present utility model is not limited to the above embodiments. Within the scope of knowledge possessed by those skilled in the art, various changes can be made without departing from the spirit of the present utility model.
