A foaming device with baffles

Abstract

This utility model relates to a foaming device with a baffle, comprising a tube body connected to a steam source; a spray hole formed on the tube body; a sleeve fitted onto the tube body; the spray hole disposed within the sleeve; and a baffle disposed within the sleeve; the spray hole facing the baffle; wherein, the baffle is inclined along the direction of steam ejection from the spray hole; one side of the inclined baffle is connected to the sleeve, and the other side is offset away from the spray hole; the steam ejected along the spray hole impacts the baffle and is deflected along the surface of the baffle. This utility model deflects part of the high-temperature steam ejected from the spray hole through the baffle. When the deflected steam impacts the milk, it applies a tangential force to the milk, pushing the milk to rotate along the deflection direction. The rotating milk cuts the milk foam to create micron-sized bubbles, making the milk foam uniform and delicate, effectively improving the appearance and taste of the milk foam.

Description

Technical Field

[0001] This utility model relates to the field of foaming device technology, and in particular to a foaming device with a baffle. Background Technology

[0002] Milk foam is made from milk and floats on the surface of coffee, which can enhance the flavor and texture of the coffee.

[0003] Traditional milk frothing devices are divided into stirring type and steam type. The stirring type is used to make cold milk foam, while the steam type is used to make hot milk foam. The steam type uses high-temperature steam to impact the milk, and the high-temperature steam entrains air, which then impacts the milk to create foam. However, the size of the milk foam produced by the impact of high-temperature steam and air is difficult to control, resulting in more large-diameter foams and uneven foam size, which ruins the appearance and taste of the milk foam.

[0004] It should be noted that the information disclosed in the background section above is only used to enhance the understanding of the background of this disclosure, and therefore may include information that does not constitute prior art known to those skilled in the art. Utility Model Content

[0005] In view of the shortcomings of the prior art, the purpose of this utility model is to provide a foaming device with baffles to improve the appearance and taste of milk foam.

[0006] The technical solution of this utility model is as follows:

[0007] The foaming device with baffles includes:

[0008] A pipe body connected to a steam source; nozzles are provided on the pipe body.

[0009] A sleeve is fitted onto the pipe body; the spray nozzle is disposed inside the sleeve;

[0010] A baffle is disposed inside the sleeve; the spray nozzle faces the baffle.

[0011] The baffle is inclined along the direction of the steam ejected from the nozzle; one side of the inclined baffle is connected to the sleeve, and the other side is offset away from the nozzle; the steam ejected along the nozzle impacts the baffle and then deflects along the surface of the baffle.

[0012] The baffle is an arc-shaped surface that protrudes towards the nozzle.

[0013] Along the axial direction of the sleeve, the baffle has a through hole on the side near the sleeve.

[0014] On the side away from the sleeve, an arc-shaped notch is formed on the baffle.

[0015] Around the spray direction of the nozzle, at least two baffles are evenly arranged circumferentially.

[0016] The direction of rotation about the axis of the sleeve; the baffles are inclined, and all the baffles are inclined in the same direction.

[0017] A connector is provided on the tube body; the sleeve is engaged with the connector.

[0018] An elastic washer is fitted around the axis of the tube body on the connector; the elastic washer is disposed between the connector and the sleeve.

[0019] Along the radial direction of the pipe body, the connector includes a diameter-reducing section; the sleeve is fitted onto the diameter-reducing section.

[0020] Along the radial direction of the tube body, the sleeve includes an enlarged section with an increased inner diameter; the enlarged section is fitted onto the connector.

[0021] The beneficial technical effects of this utility model are as follows:

[0022] (1) In the foaming device with baffle in this utility model, the high-temperature steam released by the steam source impacts the milk along the pipe and nozzle to heat the milk and generate milk foam. A sleeve is also provided, and a baffle is provided inside the sleeve. After some of the high-temperature steam is ejected along the nozzle, it first impacts the baffle and is deflected along the surface of the baffle before impacting the milk. At this time, when the steam impacts the milk after being deflected, it applies a tangential force to the milk, pushing the milk to rotate in the direction of deflection. The rotating milk cuts the milk foam to form small foam, cutting the milk into micron-sized small foams, making the milk foam uniform and delicate, effectively improving the appearance and taste of the milk foam.

[0023] (2) Furthermore, the baffle is an arc surface that protrudes towards the nozzle. The steam impacting the baffle deflects along the direction of the arc surface, reducing the resistance of the baffle to the steam, thereby reducing the energy loss when the steam impacts the baffle.

[0024] (3) Furthermore, through holes are added to the baffle. The through holes reduce the dead angle between the baffle and the sleeve, allowing air to circulate inside the sleeve and be drawn into the milk by the steam to produce milk foam. Attached Figure Description

[0035] Example 1

[0036] Figure 1 A front view structural schematic diagram of a foaming apparatus with baffles according to an embodiment of the present disclosure is shown. Figure 2 A vertical cross-sectional view of a foaming apparatus with baffles according to an embodiment of the present disclosure is shown. Figure 3 A bottom view of a foaming apparatus with baffles according to an embodiment of the present disclosure is shown. Figure 4A vertical cross-sectional perspective view of the sleeve and baffle in a foaming apparatus with a baffle according to an embodiment of this disclosure is shown. Please refer to... Figure 1 , Figure 2 , Figure 3 and Figure 4 The foaming device with baffle 5 includes a tube body 2 connected to a steam source (not shown in the figure). A nozzle 21 is formed on the tube body 2. High-temperature steam from the steam source impacts the milk along the tube body 2 and the nozzle 21 to heat the milk and generate milk foam. A sleeve 4 is fitted onto the tube body 2, forming an air chamber 3 around the tube body 2. The nozzle 21 is located inside the sleeve 4. An air hole 41 is formed on the sleeve 4, connecting to the chamber, allowing air from outside the sleeve 4 to enter the chamber through the air hole 41. A baffle 5 is located inside the sleeve 4. The nozzle 21 faces the baffle 5.

[0037] In this design, the baffle 5 is inclined along the direction of the steam ejected from the nozzle 21. A sleeve 4 is connected to one side of the inclined baffle 5, which is offset away from the nozzle 21 on the other side. The steam ejected along the nozzle 21 impacts the baffle 5 and then deflects along its surface. Specifically, some of the high-temperature steam ejected along the nozzle 21 first impacts the baffle 5 and deflects along its surface before impacting the milk. The deflected steam then applies a tangential force to the milk, causing it to rotate in the direction of deflection. This rotating milk cuts and foams the milk, breaking it into micron-sized bubbles, resulting in uniform and delicate foam that effectively improves the appearance and texture of the milk foam.

[0038] Please refer to Figure 2 and Figure 4 The baffle 5 is an arc surface 53 that protrudes towards the nozzle 21. The steam impacting the baffle 5 is deflected along the arc surface 53, reducing the resistance of the baffle 5 to the steam and thus reducing the energy loss when the steam impacts the baffle 5.

[0039] Preferably, along the axial direction of the sleeve 4, the baffle 5 has a through hole 51 on the side closest to the sleeve 4. The through hole 51 reduces the dead angle between the baffle 5 and the sleeve 4, facilitating the flow of air within the sleeve 4, which is then drawn into the milk by steam to produce milk foam.

[0040] More preferably, an arc-shaped notch 52 is formed on the side of the baffle 5 away from the sleeve 4. The arc-shaped notch 52 reduces the contact area between the baffle 5 and the high-temperature steam, thereby reducing the resistance between the baffle 5 and the high-temperature steam. Furthermore, since the baffle is tilted, the reduction in the working surface of the baffle 5 in the lateral direction due to the arc-shaped notch 52 is limited, and its impact on the baffle 5's ability to deflect steam is also limited.

[0041] Please refer to Figure 2 and Figure 4A connector 1 is provided on the tube body 2. The sleeve 4 is snapped into the connector 1. Specifically, the sleeve 4 and the connector 1 are interlocked by an interference fit, which facilitates the installation and removal of the sleeve 4. Removing the sleeve 4 will also remove the baffle 5, which can meet some application scenarios where the direction of steam flow does not need to be deflected, and improve the versatility of the foaming device with baffle 5. In some embodiments, the tube body 2 can be made of metal, which can facilitate the use of the tube body 2 alone.

[0042] Preferably, an elastic washer 12 is fitted onto the connector 1 around the axis of the pipe body 2. The elastic washer 12 is disposed between the connector 1 and the sleeve 4. The sleeve 4 and the connector 1 are interference-fitted by the elastic washer 12. The elastic washer 12 elastically deforms to fill the gap between the sleeve 4 and the connector 1, and applies an elastic force to the sleeve 4 and the connector 1 to connect the sleeve 4 and the connector 1.

[0043] More preferably, along the radial direction of the pipe body 2, the connector 1 includes a reduced diameter section 11. The sleeve 4 is fitted onto the reduced diameter section 11. A first step 13 is formed between the conventional diameter position of the connector 1 and the reduced diameter section 11.

[0044] Along the radial direction of the pipe body 2, the sleeve 4 includes an enlarged section 42 with an increased inner diameter. The enlarged section 42 is fitted onto the connector 1. A second step 43 is formed between the conventional inner diameter of the sleeve 4 and the enlarged section 42. The first step 13 engages with a second adjustment to position the axial position between the connector 1 and the sleeve 4.

[0045] Example 2

[0046] Figure 5 A cross-sectional view of the sleeve and baffle in a foaming apparatus with baffle according to an embodiment of the present disclosure is shown. Figure 6 A vertical cross-sectional perspective view of the sleeve and baffle in a foaming apparatus with a baffle according to an embodiment of this disclosure is shown. Please refer to... Figure 5 and Figure 6 ,

[0047] Example 2 is largely the same as Example 1 in structure and workflow. The difference is that at least two baffles 5 are evenly arranged circumferentially around the spray direction of the nozzle 21. The baffles 5 are tilted in the direction of rotation around the axis of the sleeve 4, and all baffles 5 are tilted in the same direction. Multiple baffles 5 act simultaneously, deflecting the steam flow separately and consistently, forming a vortex that agitates the milk, causing the agitated milk to break down and refine the milk foam.

[0048] The specific workflow of this utility model is as follows:

[0049] The user moves the foaming device with baffle 5 until the end of the sleeve 4 near the nozzle 21 extends into the milk. At this point, baffle 5 can be positioned directly in front of the milk or partially immersed in it. Then, the steam source is activated. High-temperature steam is ejected along the nozzle 21. Some of the ejected high-temperature steam impacts baffle 5 and deflects along its surface before impacting the milk. The deflected steam then applies a tangential force to the milk, causing it to rotate in the direction of deflection. The rotating milk cuts the milk foam, creating small bubbles.

[0050] When there are two or more baffles 5, the multiple baffles 5 work simultaneously, deflecting the steam they come into contact with in a consistent manner, forming a vortex to stir the milk.

[0051] The technical features of the above embodiments can be combined in any way. For the sake of brevity, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0052] The embodiments described above are merely illustrative of several implementations of this utility model, and while the descriptions are relatively specific and detailed, they should not be construed as limiting the scope of the utility model patent. It should be noted that those skilled in the art can make various modifications and improvements without departing from the concept of this utility model, and these all fall within the protection scope of this utility model. Therefore, the protection scope of this utility model patent should be determined by the appended claims.
