Description

Technical Field

[0001] This utility model relates to the field of kitchen appliance technology, and in particular to an electric milk frother. Background Technology

[0002] When making some coffee drinks, such as lattes and cappuccinos, milk needs to be heated to a certain temperature, and then the heated milk is frothed into a fine and smooth foam before being mixed with coffee. In existing solutions, milk frothers are usually used to heat and froth the milk to form foam.

[0003] However, the containers used to froth milk are not always consistent. If using an electric milk frother, in addition to preheating the milk, you also need to manually control the depth of the electric milk frother inside the container and keep it still, which can be tiring for the user. If using a fixed steam milk frother, you need to manually bring the container of milk close to the steam-generating structure so that the steam can rush into the milk to froth it and create milk foam. However, this poses a certain risk, as the user may be burned due to improper operation.

[0004] Therefore, existing technologies still need to be improved and developed. Utility Model Content

[0018] Furthermore, the stirring and foaming component includes:

[0019] A stirring base, wherein the end of the adjusting connecting rod away from the support frame is rotatably mounted on the stirring base;

[0021] A stirring head is installed at the end of the rotating telescopic rod away from the stirring base.

[0022] Furthermore, a second receiving groove is provided inside the stirring base, and the end of the adjusting connecting rod away from the support frame is rotatably installed in the second receiving groove. Second rotating holes are provided on both sides of the second receiving groove.

[0023] One end of the adjusting connecting rod that extends into the second receiving groove is provided with:

[0024] The second fitting hole corresponds to the second rotating hole;

[0025] The second rotating shaft passes through the second rotating hole and the second sleeve hole respectively, so that the stirring and foaming component rotates around the adjusting connecting rod.

For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection between two components. Those skilled in the art can understand the specific meaning of the above terms in this application based on the specific circumstances.

[0045] This embodiment provides an electric milk frother, such as... Figures 1 to 6As shown, this invention solves the problems of existing solutions requiring the electric milk frother to be inserted deep into the container and kept stationary, and the container to be close to the steam-generating structure. It uses an adjustable frothing structure that extends into the milk in the container and remains fixed, thus frothing the milk in a time-saving and labor-saving manner. Specifically, the electric milk frother includes a support assembly 100, a lifting assembly 200, a stirring and frothing component 300, and a heating component 400. One end of the lifting assembly 200 is mounted on the support assembly 100, while the stirring and frothing component 300 is mounted on the other end. The position of the stirring and frothing component 300 is changed by raising and lowering the lifting assembly 200 relative to the support assembly 100. Since the milk also needs to be heated during frothing, a heating component 400 is also provided. The heating component 400 is located below the stirring and frothing component 300 and spaced apart from it. The container can be a frothing pitcher or other liquid container. In this application, the heating element 400 is a heating plate that heats the container placed on it through electromagnetic induction, thereby heating the milk inside the container. Correspondingly, the container should be made of metal. In other embodiments, the heating element 400 can also heat the milk through infrared radiation or other methods, in which case it is not necessary to restrict the container to be made of metal.

[0046] Specifically, such as Figures 1 to 3 As shown, the lifting assembly 200 includes an adjusting rod 210. One end of the adjusting rod is rotatably mounted on the support frame 120 of the support assembly 100, allowing the adjusting rod 210 to rotate relative to the support frame 120, thus changing the position of the end of the adjusting rod 210 away from the support frame 120. A stirring and frothing component 300 is rotatably mounted on the other end of the adjusting rod 210. Rotating the adjusting rod 210 adjusts the position of the stirring and frothing component 300. Specifically, when the stirring and frothing component 300 is rotatably mounted on the adjusting rod 210, the adjusting rod 210 is also rotatably mounted on the support frame 120. Therefore, when milk needs to be frothed, rotating the adjusting rod 210 and the stirring and frothing component 300 causes the stirring and frothing component 300 to move downwards, away from the support frame 120, as shown. Figure 1 As shown, the stirring and frothing component 300 gradually extends into the container containing milk to froth the milk. After frothing is complete, the adjusting rod 210 and the stirring and frothing component 300 are rotated in opposite directions, causing the stirring and frothing component 300 to move upwards and closer to the support frame 120. At this time, the stirring and frothing component 300 gradually moves away from the container containing milk until it is completely removed from the container. In this application, in order to better allow the stirring and frothing component 300 to change its position by rotation, two adjusting rods 210 are provided. The first adjusting rod 210 bends inward at a smaller angle, which is an obtuse angle, while the second adjusting rod 210 bends inward at a larger angle, which is a right angle, thereby better allowing the two adjusting rods 210 to rotate.

[0047] In addition, in order to keep the support frame 120 stable and prevent the support frame 120 from tipping over when the adjusting linkage 210 rotates, thus affecting the use of the electric milk frother, a support base 110 is also provided. The support base 110 and the support frame 120 form a support assembly 100. The support frame 120 is vertically installed on the support base 110. The support base 110 is used to place the container holding the milk, so that the container holding the milk does not need to be manually held when frothing the milk. The support frame 120 is long and narrow, and the support frame 120 is perpendicular to the support base 110. The heating element 400 is installed on the side of the support base 110 facing the stirring and frothing element 300.

[0048] Furthermore, in order to allow the adjusting rod 210 to rotate around the support frame 120, the support frame 120 is provided with a first receiving groove 121. The first receiving groove 121 is specifically located at the end of the support frame 120 away from the support base 110, and the adjusting rod 210 is rotatably installed in the first receiving groove 121. The first receiving groove 121 is rectangular in shape, and the two adjusting rods 210 in this application are stacked vertically and rotatably installed in the first receiving groove 121. In order to allow the adjusting rod 210 to rotate stably in the first receiving groove 121, to prevent the adjusting rod 210 from shaking during rotation, and to prevent the adjusting rod 210 from falling out of the first receiving groove 121, first rotating holes 122 are provided on both sides of the first receiving groove 121. Since there are two adjusting rods 210 in this application, two first rotating holes 122 are provided on each side of the first receiving groove 121, for a total of four first rotating holes 122. In addition, the end of the adjusting rod 210 that extends into the first receiving groove 121 is provided with a first sleeve hole 211 and a first rotating shaft 212. The first sleeve hole 211 corresponds to the first rotating hole 122. The first rotating shaft 212 passes through the first rotating hole 122 and the first sleeve hole 211 respectively, so that the first sleeve hole 211 rotates around the first rotating shaft 212, thereby causing the adjusting rod 210 to rotate relative to the first rotating hole 122, and then causing the adjusting rod 210 to rotate around the support frame 120, ultimately realizing the position adjustment of the stirring and foaming component 300.

[0049] The mixing and frothing component 300 includes a mixing base 310, a rotating telescopic rod 320, and a mixing head 330. An adjusting rod 210 is rotatably mounted on the mixing base 310 at its end furthest from the support frame 120, allowing the mixing base 310 to rotate around the adjusting rod 210, thus enabling the mixing and frothing component 300 to adjust its position. The rotating telescopic rod 320 is connected to the mixing base 310 via a transmission mechanism, and its rotation is driven by the mixing base 310. The length of the rotating telescopic rod 320 can be adjusted as needed to accommodate different containers. The mixing head 330 is mounted on the end of the rotating telescopic rod 320 furthest from the mixing base 310. The rotation of the rotating telescopic rod 320 drives the mixing head 330 to rotate, thereby frothing the milk to form milk foam.

[0050] To facilitate better rotation between the adjusting rod 210 and the stirring base 310, a second receiving groove 311 is provided inside the stirring base 310. The end of the adjusting rod 210 away from the support frame 120 is rotatably installed in the second receiving groove 311. The second receiving groove 311 is rectangular in shape, and the two adjusting rods 210 in this application are stacked vertically and rotatably installed in the second receiving groove 311. To ensure stable rotation of the adjusting rod 210 within the second receiving groove 311, prevent the adjusting rod 210 from shaking during rotation, and prevent the adjusting rod 210 from falling out of the second receiving groove 311 and causing the stirring and frothing component 300 to detach from the electric milk frother, second rotating holes 312 are provided on both sides of the second receiving groove 311. Since there are two adjusting rods 210 in this application, two second rotating holes 312 are provided on each side of the second receiving groove 311, for a total of four second rotating holes 312. In addition, the end of the adjusting rod 210 that extends into the second receiving groove 311 is provided with a second sleeve hole 213 and a second rotating shaft 214. The second sleeve hole 213 corresponds to the second rotating hole 312. The second rotating shaft 214 passes through the second rotating hole 312 and the second sleeve hole 213 respectively, so that the second sleeve hole 213 rotates relative to the second rotating hole 312 by rotating around the second rotating shaft 214, thereby causing the adjusting rod 210 to rotate relative to the stirring base 310, thereby realizing the position adjustment of the stirring and foaming component 300.

[0051] In addition, the stirring base 310 also includes a rotating component, and the rotating telescopic rod 320 is connected to the rotating component for transmission. The rotating component drives the rotating telescopic rod 320 to rotate, thereby foaming the milk in the container. In this application, the rotating component is a motor, which drives the rotating telescopic rod 320 to rotate. In other embodiments, it may be other structures. Since the rotating component is a structure existing in the prior art, it will not be specifically described. In this application, the stirring head 330 is inserted into the milk to foam it. Therefore, the stirring head 330 includes a stirring blade 331 and a stirring filter 332. The stirring blade 331 is installed at the end of the rotating telescopic rod 320 away from the stirring base 310. The stirring filter 332 is sleeved on the outer ring of the stirring blade 331 to avoid contact with the stirring blade 331 and thus prevent injury. At the same time, the stirring filter 332 can also improve the efficiency of milk foam generation. Specifically, when the rotating component drives the telescopic rod 320 to rotate, the telescopic rod 320 drives the stirring blade 331 to rotate, thereby forming a vortex in the milk. After the vortex is formed, the upper part of the stirring blade 331 can come into contact with air. The rotation of the stirring blade 331 will transport air into the milk. Since the stirring filter 332 surrounding the stirring blade 331 has many dense small holes, the air will escape from the small holes of the stirring filter 332 during the transport process, forming tiny bubbles, which in turn generate bubbles in the milk, forming milk foam.

[0052] Since milk needs to be kept within a specific temperature range when frothing it, such as between 50-70°C, the electric milk frother also includes a temperature control probe 500. The temperature control probe 500 is installed on the side of the mixing base 310 facing the support base 110. The temperature control probe 500 is electrically connected to the heating element 400. The temperature control probe 500 monitors the temperature of the milk in the container in real time. When the temperature is lower than the set temperature, the temperature control probe 500 controls the heating element 400 to heat the container. When the temperature is higher than the set temperature, the temperature control probe 500 controls the heating element 400 to stop heating.

[0053] The electric milk frother also includes a control unit 600, which is mounted on a support base 110. The control unit 600 is electrically connected to the heating element 400 and the temperature control probe 500. The control unit 600 controls the operation of the temperature control probe 500 and the heating element 400. To precisely adjust the heating temperature, the control unit 600 includes a knob mounted on the support base 110. Rotating the knob adjusts the heating temperature. Additionally, the knob can be used to adjust the rotation speed of the telescopic rod 320, achieving stepless speed adjustment for more precise speed control and better frothing of the milk. Furthermore, the control unit 600 is also electrically connected to the stirring and frothing element 300 to control whether the rotating element rotates.

[0054] Additionally, a milk collection tray 111 can be detachably installed on the support base 110. The milk collection tray 111 is attached to the support frame 120 and catches any residual milk dripping from the mixing head 330. This is because when the mixing and frothing component 300 is removed from the container, milk may remain on the mixing head 330, and this residual milk will drip downwards under gravity. Therefore, catching the milk dripping from the mixing head 330 with the milk collection tray 111 prevents milk from dripping onto the support base 110 or other locations, thus maintaining the cleanliness and hygiene of the electric milk frother.

[0055] In other embodiments, the lifting assembly 200 further includes a lifting rod 220, such as Figures 4 to 6 As shown, one end of the lifting rod 220 is fixed to the support base 110 of the support assembly 100, and the stirring and foaming component 300 is installed at the other end of the lifting rod 220. The lifting rod 220 drives the stirring and foaming component 300 to rise and fall. At this time, the container is first placed on the support base 110, and then the lifting rod 220 drives the stirring and foaming component 300 to descend and extend into the container for stirring. After stirring is completed, the lifting rod 220 drives the stirring and foaming component 300 to rise and move away from the container until the stirring and foaming component 300 is removed from the container.

[0056] Specifically, such as Figure 4 As shown, a connecting rod 221 is provided at the end of the lifting rod 220 away from the support base 110. The stirring and foaming component 300 is installed at the end of the connecting rod 221 away from the lifting rod 220. The lifting rod 220 drives the connecting rod 221 to rise and fall, thereby driving the stirring and foaming component 300 to rise and fall.

[0057] In another embodiment, to prevent the lifting rod 220 from being damaged, such as Figure 5 As shown, a protective element 222 is also provided at the end of the lifting rod 220 away from the support base 110, which protects the lifting rod 220.

[0058] In addition, to facilitate changing the angle of the mixing and frothing component 300, allowing it to better whip the milk in the container, such as... Figure 6 As shown, a rotating component 223 is provided in the middle of the lifting rod 220. At this time, the part of the lifting rod 220 used for lifting and lowering is located at the upper end of the lifting rod 220. The connecting rod 221 and the protective component 222 are both installed at the upper end of the lifting rod 220. Therefore, the connecting rod 221 can change its angle by rotating the rotating component 223, thereby changing the angle of the stirring and frothing component 300. Furthermore, the vertical height of the stirring and frothing component 300 can be changed by lifting and lowering the upper end of the rotating component 223. Ultimately, both the angle and height of the stirring and frothing component 300 can be changed, allowing the stirring and frothing component 300 to better froth the milk.

[0059] Therefore, when using the electric milk frother of this application to froth milk in a container to form milk foam, the container containing milk is first placed on the support base 110. The heating element 400 is controlled by the control unit 600 to heat the milk and to control the rotation speed of the telescopic rod 320. Then, the stirring and frothing element 300 is lowered by the lifting component 200, so that the stirring head 330 of the stirring and frothing element 300 extends into the container. The rotating element is started by the control unit 600, which drives the telescopic rod 320 to rotate, thereby driving the stirring blade 331 to rotate, thus frothing. After frothing is completed, the stirring and frothing element 300 is raised by the lifting component 200 to remove the stirring and frothing element 300 from the container. The rotating element is stopped by the control unit 600, and the milk is removed from the support base 110, thus completing the milk frothing work.

[0060] It should be understood that the application of this utility model is not limited to the examples above. Those skilled in the art can make improvements or modifications based on the above description, and all such improvements and modifications should fall within the protection scope of the appended claims.
