Description

Technical Field

[0001] This utility model relates to the field of coffee machine technology, and in particular to a combined steam milk wand. Background Technology

[0002] A steam milk wand is a functional extension component of a coffee machine. It sprays high-pressure steam into the milk cup, where the high-pressure steam interacts with the milk to form fine and dense milk foam.

[0003] In some technical solutions, the steam jets of a milk wand are directly exposed to facilitate contact with the milk. When using a milk wand to froth milk, the high-pressure steam can reach temperatures of 120-150℃. Milk impacted by the steam jets can easily splash onto the user's skin, potentially causing severe burns. This is especially true when the milk wand is not fully submerged in the liquid, or when it is offset at an angle relative to the liquid surface (generally, a 30°–50° angle is recommended when frothing milk). Furthermore, splashed milk can adhere to the milk wand, the coffee machine casing, or the work surface during frothing, making cleaning difficult and increasing the risk of bacterial growth.

[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

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

[0007] The combined steam milk bar includes:

[0008] A rod body has a steam hole and a spray hole; the steam hole is connected to a steam source; the spray hole is connected to the steam hole and the outer surface of the rod body; a limiting protrusion extends along the radial direction of the rod body;

[0009] A cylindrical body is sleeved on the rod body; a limiting groove is formed on the cylindrical body along the axial direction of the rod body, and the limiting groove communicates with the end surface of the cylindrical body; a strip groove is formed on the cylindrical body around the axis of the rod body;

[0010] The limiting groove is connected to the strip groove; when the cylinder is fitted onto the rod, the limiting protrusion is engaged into the strip groove along the limiting groove.

[0011] A further technical solution is that the cylinder includes a sleeve fitted on the rod and a collar fitted on the sleeve; the strip groove is formed on the collar; the limiting groove includes part A formed on the sleeve and part B formed on the collar.

[0012] A further technical solution is that a first groove and a first clearance groove are formed on the surface of the sleeve that contacts the collar; the first groove is arranged around the axis of the rod; the first clearance groove is arranged along the axial direction of the rod and communicates with the first groove; a first extension is provided on the surface of the collar that contacts the sleeve and engages with the first groove; wherein, the first clearance groove is close to the end surface of the sleeve, so that the first extension can engage with the first clearance groove.

[0013] A further technical solution is that a positioning protrusion is provided on the bottom surface of the first clearance groove near the end of the first groove, extending radially along the rod body.

[0014] A further technical solution is that at least two first extensions are provided along the radial direction of the rod.

[0015] A further technical solution is that a second groove and a second clearance groove are formed on the surface of the sleeve that contacts the collar; the second groove is arranged around the axis of the rod; the second clearance groove is arranged along the axial direction of the rod, and the second clearance groove connects the second groove and the end surface of the sleeve; a second extension is provided on the surface of the collar that contacts the sleeve and is inserted into the second groove; the first extension and the second extension are symmetrically arranged around the axis of the rod.

[0016] A further technical solution is that a connector is provided between the rod and the steam source; a connection hole is opened on the connector to connect to the steam source; the outer shape of the connector is larger than the outer shape of the rod along the radial direction of the rod; the cylinder is sleeved on the connector, and a gap is left between the cylinder and the rod.

[0017] A further technical solution is that a through hole is formed on the cylinder; the through hole connects to the gap.

[0018] A further technical solution is to provide a washer on the connector head around the axis of the rod; the washer is disposed between the connector head and the rod.

[0019] A further technical solution is that a protective sleeve is also fitted onto the cylinder.

[0020] The beneficial technical effects of this utility model are as follows:

[0021] (1) The combined steam milk stick of this utility model has steam holes and nozzles on the stick body, which guides the steam to impact the milk to generate milk foam or heat it. In addition, the combined steam milk stick of this application also has a cylinder on the stick body, which covers the stick body to prevent the steam from the nozzle from directly impacting the milk and causing milk to splash. At the same time, the cylinder covers the stick body to prevent the user from being burned by direct contact with the stick body, effectively improving the safety performance of the stick body. The cylinder body and the stick body are connected by a limiting protrusion and a strip groove. The user only needs to rotate the cylinder body around the stick body to align the limiting protrusion and the limiting groove to quickly disassemble and assemble the cylinder body and the stick body. After removing the cylinder body, the combined steam milk stick is smaller in size, making it easier to insert into a small cup, and the cylinder body no longer covers the nozzle, making it easier for the user to directly observe the interaction between the steam and the milk.

[0022] (2) Furthermore, the cylinder is divided into a sleeve fitted onto the rod and a collar fitted onto the sleeve. The sleeve and collar can be made of different materials to ensure their sealing performance while effectively isolating the rod from the heat of the steam and protecting the user.

[0023] (3) Furthermore, the sleeve and the collar are also connected by a snap-fit ​​structure, which makes disassembly and assembly simple and convenient, ensuring the flexibility of disassembly and assembly between the rod and the sleeve. Attached Figure Description

[0033] Figure 1 A front view schematic diagram of a combined steam milk stick according to an embodiment of the present disclosure is shown. Figure 2 A vertical cross-sectional schematic diagram of a combined steam milk stick according to an embodiment of the present disclosure is shown. Figure 3 An exploded structural diagram of a combined steam milk stick according to an embodiment of this disclosure is shown. Please refer to... Figure 1 , Figure 2 and Figure 3The combined steam milk wand includes a wand 3 with a steam hole 31 and a nozzle 32. The steam hole 31 is connected to a steam source. The nozzle 32 connects the steam hole 31 and the outer surface of the wand 3. High-pressure steam impacts the milk along the steam hole 31 and the nozzle 32 to generate milk foam or heat the milk. A limiting protrusion 11 extends radially from the wand 3. A cylindrical body is fitted onto the wand 3. The cylindrical body covers the wand 3 to prevent milk from splashing after steam impacts the milk. Simultaneously, the cylindrical body covers the wand 3 to prevent users from being burned by direct contact with the wand 3, effectively improving the safety of using the wand 3. A limiting groove 42 is formed on the cylindrical body along the axial direction of the wand 3, connecting to the end surface of the cylindrical body. This allows the limiting protrusion 11 to engage with the limiting groove 42 along the end surface of the cylindrical body when the cylindrical body is fitted onto the wand 3. A strip groove 63 is formed around the axis of the wand 3. The limiting groove 42 connects to the strip groove 63. When the cylindrical body is fitted onto the rod 3, the limiting protrusion 11 engages with the strip groove 63 along the limiting groove 42. The user only needs to rotate the cylindrical body around the rod 3, and the limiting protrusion 11 slides within the strip groove 63. At this time, along the axis of the rod 3, the limiting protrusion 11 is misaligned with the limiting groove 42, thereby engaging and connecting the rod 3 and the cylindrical body. The assembly and disassembly of the rod 3 and the cylindrical body are convenient. The combined milk stick with the cylindrical body removed has a smaller volume, making it easier to insert into the lower cup opening, and by no longer obstructing the nozzle 32, it is easier for the user to directly observe the interaction between the steam and the milk.

[0034] In some embodiments, the nozzle 32 of the rod 3 is completely located inside the sleeve 5. When the combined steam milk stick is inserted into the milk and sprays high-pressure steam, since the sleeve 5 prevents air from entering, no air is entrained in the milk when the high-pressure steam impacts it. The high-pressure steam only heats the milk and does not whip it.

[0035] Figure 4 A three-dimensional structural schematic diagram of the collar in a combined steam milk stick according to an embodiment of this disclosure is shown. Please refer to... Figure 2 , Figure 3 and Figure 4The cylinder includes a sleeve 5 fitted onto the rod 3 and a collar 6 fitted onto the sleeve 5. A strip groove 63 is formed on the collar 6. A limiting groove 42 includes a portion A 421 formed on the sleeve 5 and a portion B 422 formed on the collar 6. The sleeve 5 and collar 6 are separate components and can be made of different materials to optimize the performance of the cylinder. In some embodiments, the sleeve 5 can be a Teflon tube. Teflon tubes have high stability and high temperature resistance, and even if milk or detergent residue remains, it will not cause the tube to age, ensuring food safety. The collar 6 can be made of stainless steel or copper to enhance the structural strength of the entire cylinder. Specifically, along the radial direction of the rod 3, portion A 421 extends through the entire sleeve 5, and portion B 422 is formed on the surface of the collar 6 near the sleeve 5. Portion B 422 does not connect to the surface of the collar 6 away from the sleeve 5 to avoid affecting the structural strength of the collar 6.

[0036] Preferably, a protective sleeve 7 is also fitted onto the sleeve 5. The protective sleeve 7 and the collar 6 cooperate to fit onto the surface of the sleeve 5, providing more comprehensive coverage of the outer surface of the sleeve 5. Furthermore, when the collar 6 rotates around the protective sleeve 7, it does not need to drive the protective sleeve 7 to rotate synchronously, making it convenient for the user to rotate the collar 6 around the sleeve 5.

[0037] Figure 5 A three-dimensional structural schematic diagram of the sleeve in a combined steam milk stick according to an embodiment of the present disclosure is shown. Please refer to... Figure 2 , Figure 3 and Figure 5 A first groove 51 and a first clearance groove 511 are formed on the surface of the sleeve 5 that contacts the collar 6. The first groove 51 is arranged around the axis of the rod 3. The first clearance groove 511 is arranged along the axial direction of the rod 3 and is connected to the first groove 51. A first extension 61 is provided on the surface of the collar 6 that contacts the sleeve 5 and engages with the first groove 51. The first clearance groove 511 is close to the end surface of the sleeve 5, which facilitates the engagement of the first extension 61 with the first clearance groove 511. By engaging the first extension 61 with the first groove 51 along the first clearance groove 511, the sleeve 5 and the collar 6 can be connected. The first clearance groove 511 is not connected to the end surface of the sleeve 5, ensuring the structural strength of the sleeve 5. At the same time, if the collar 6 is pulled directly along the axis of the rod 3, the first extension 61 will interfere with the side wall of the first clearance groove 511. The position between the collar 6 and the rod 3 needs to be deflected in order to remove the collar 6 from the sleeve 5. This prevents the collar 6 from falling directly off the sleeve 5 when the first extension 61 accidentally slides into the first clearance groove 511, thus enhancing the safety performance of the combined steam milk stick.

[0038] Preferably, a positioning protrusion 512 is provided on the bottom surface of the first clearance groove 511 near the end of the first groove 51, extending radially along the rod body 3. When the first extension 61 slides into the first groove 51 along the first clearance groove 511, the first extension 61 will interfere with the positioning protrusion 512, causing the collar 6 to vibrate and produce a noticeable jerking sensation. By sensing the vibration of the collar 6, the user can quickly determine whether the first extension 61 is stuck in the first groove 51, thus optimizing the assembly feel between the sleeve 5 and the collar 6.

[0039] In some embodiments, at least two first extensions 61 are provided along the radial direction of the rod 3, and the two first extensions 61 simultaneously engage with the inner wall of the first groove 51. The provision of two first extensions 61 increases the contact points between the sleeve 5 and the collar 6, increases the contact area between the sleeve 5 and the collar 6, distributes the load, reduces the risk of local deformation or breakage of the first extensions 61 due to stress concentration, and enhances the stability and fault tolerance of the connection structure between the sleeve 5 and the collar 6.

[0040] More preferably, a second groove 52 and a second clearance groove 521 are formed on the surface of the sleeve 5 that contacts the collar 6. The second groove 52 is arranged around the axis of the rod body 3. The second clearance groove 521 is arranged along the axial direction of the rod body 3. A second extension 62 is provided on the surface of the collar 6 that contacts the sleeve 5 and engages with the second groove 52. The first extension 61 and the second extension 62 are symmetrically arranged around the axis of the rod body 3. The first extension 61, the first groove 51, the second extension 62 and the second groove 52 cooperate to transmit the load between the sleeve 5 and the collar 6 more evenly through symmetrical mechanical distribution, thereby comprehensively optimizing the strength and stability of the connection structure between the sleeve 5 and the collar 6.

[0041] The second clearance groove 521 connects the second recess 52 and the end surface of the sleeve 5. Since the first clearance groove 511 does not connect to the end surface of the sleeve 5, when the first extension 61 is inserted into the first clearance groove 511, the collar 6 needs to be deflected around the axis of the sleeve 5 to engage the first extension. If the second clearance groove 521 also did not connect to the end surface of the sleeve 5, the engagement connection between the sleeve 5 and the collar 6 would be difficult. Therefore, the second clearance groove 521 connects to the end surface of the sleeve 5, facilitating the engagement connection between the sleeve 5 and the collar 6.

[0042] Please refer to Figure 2 and Figure 3 A connector 1 is provided between the rod body 3 and the steam source. A connection hole 12 is provided on the connector 1 to connect to the steam source. Along the radial direction of the rod body 3, the outer shape of the connector 1 is larger than that of the rod body 3. The cylinder is sleeved on the connector 1, and a gap 41 is left between the cylinder and the rod body 3 by connecting and supporting the cylinder. The gap 41 effectively isolates the heat transfer between the cylinder and the rod body 3, reducing the temperature of the sleeve 5 and the collar 6.

[0043] In some embodiments, a through hole 53 may be provided on the cylinder, which connects to the gap 41. The through hole 53 facilitates the flow of air along the gap 41 to the position where the high-pressure steam contacts the milk. The high-pressure steam impacts the milk while entraining air to generate milk foam. The sleeve 5 covers the rod 3 to prevent milk from splashing after the steam impacts the milk, and to prevent the user from being burned by direct contact with the rod 3, while not hindering the formation of milk foam.

[0044] In other embodiments, a washer 2 is fitted onto the connector 1 around the axis of the rod 3. The washer 2 is positioned between the connector 1 and the rod 3. The washer 2 can be made of an elastic material such as silicone. The elastic deformation of the washer 2 supports the collar 6, reduces the gap 41 between the connector 1 and the sleeve 5, and enhances the stability of the connection between the connector 1 and the sleeve 5. Furthermore, the elastic deformation of the washer 2 fills the gap 41 between the connector 1 and the sleeve 5, enhancing the sealing performance between the connector 1 and the sleeve 5 and preventing vapor leakage and air ingress.

[0045] The specific assembly process of this utility model is as follows:

[0046] Incline the collar 6 along the axis of the sleeve 5 and move it towards the sleeve 5 until the first extension 61 engages with the first groove 51. Then, swing the collar 6 to align the axis between the sleeve 5 and the collar 6, and engage the second extension 62 with the second clearance groove 521. Place the collar 6 onto the sleeve 5 along its axis. At this time, the first extension 61 slides along the first clearance groove 511, and the second extension 62 slides along the second clearance groove 521 until the second extension 62 passes the positioning protrusion 512. The operator will then feel a slight jolt as the collar 6 is fitted onto the sleeve 5 to form the cylinder. Next, rotate the collar 6 around the axis of the sleeve 5 to align part A 421 and part B 422. Align the axes of the cylinder and the rod 3, and align the limiting protrusion 11 and the limiting groove 42 along the axis of the cylinder. The cylinder is fitted onto the rod 3 from the nozzle 32 toward the connector 1 until the limiting protrusion 11 slides into the strip groove 63 along the limiting groove 42. Finally, the collar 6 is rotated around the sleeve 5. At this time, the limiting protrusion 11 slides in the strip groove 63, and the position of the limiting protrusion 11 is offset from that of part B 422, completing the assembly of the combined steam milk stick.

[0047] 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.

[0048] 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.
