Abstract
Description
Technical Field
[0001] This utility model relates to the field of steam milk sticks, and more particularly to a nozzle for a steam milk stick. Background Technology
[0002] When a steam milk maker froths milk, it sprays high-speed gas into the milk. The gas flow causes the milk to rotate, and during the rotation, air is drawn into the milk, forming fine foam.
[0003] In some technical solutions, a steam milk wand has a hollow cylindrical structure, through which high-speed gas passes to impact the milk. Typically, the hollow section of a straight cylinder has a relatively large diameter, resulting in a sparser gas flow. This means the gas only affects the milk around the steam wand. Therefore, during the frothing process, the milk container needs to be constantly moved to ensure all the milk is fully frothed.
[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 nozzle for a steam milk stick, so as to solve the problem that the existing technology can only act on the milk around the steam milk stick, and requires constant movement of the milk container to ensure that all the milk is fully steamed.
[0006] To achieve the above objectives, the technical solution of this utility model is as follows:
[0007] A nozzle for a steam milk stick;
[0008] It includes: a cylindrical body; a central opening and a side outlet connected to the outlet of the cylindrical body; wherein, a pressure plane is formed on the outer side of the side outlet, and gas flows along the pressure plane to accumulate; the cross-sectional area of the cylindrical body is greater than the sum of the cross-sectional areas of the central opening and the side outlet.
[0009] A further technical solution is to stamp the cylinder outlet to form the intermediate opening and the side outlets distributed outside the intermediate opening; the number of the side outlets is not less than two sets.
[0010] A further technical solution is that the cylinder body forms an arc transition towards the side outlet.
[0011] A further technical solution is to form an angle around the central opening, with the angle corresponding to the side outlet.
[0012] A further technical solution is that the pressure plane interval is formed on each of the side outlets.
[0013] A further technical solution is that the side outlet forms an extended edge along the gas flow direction; the pressure plane transitions towards the extended edge.
[0014] A further technical solution is that the extended side is connected to the cylinder near the side outlet position.
[0015] A further technical solution is that the extended side is disposed on the ring sleeve; the ring sleeve is disposed at the outlet of the cylinder.
[0016] Compared with the prior art, the beneficial technical effects of this utility model are as follows:
[0017] (1) The gas inside the cylinder flows downward, flows along the pressure plane and accumulates at the side outlet. The gas flows downward from the side outlet. Because there is a lot of accumulated gas, the gas flow path is long, which avoids the gas from diffusing after entering the milk. The gas will only diffuse when it acts on the bottom of the milk container, so that the gas can act on a larger area at the bottom of the milk container, which improves the efficiency of frothing or heating. The cross-sectional area of the cylinder is larger than the sum of the cross-sectional areas of the middle opening and the side outlet, so that the gas in the cylinder flows out through the middle opening and the side outlet at a faster speed. At the same time, the gas in the cylinder is divided into several streams that flow out from the middle opening and the side outlet respectively, so that the gas and the milk can fully contact each other, which improves the efficiency of frothing or heating.
[0018] (2) The gas inside the cylinder flows out through the side outlet without any resistance, resulting in a faster gas flow rate; when the gas transitions to the pressure plane along the side outlet, the gas can accumulate smoothly.
[0019] (3) By forming the edges, when the gas in the cylinder flows out through the middle opening, the gas forms the corresponding edge shape, and the contact area between the gas and the milk increases to achieve full contact, thereby improving the efficiency of foaming or heating.
[0020] (4) The gas flowing out of the nozzle of the steam milk stick can be divided into multiple streams. The gas flows out from the middle opening of the cylinder to form the first stream of gas into the milk. The gas flows out from the side outlet of the cylinder to form the second stream of gas into the milk. The gas flows from the cylinder through the pressure surface and accumulates with the gas from the side outlet to form the third stream of gas, which acts on the bottom of the milk container and diffuses. The accumulated gas continues to flow along the extended side, which can strengthen the impact force of the third stream of gas on the bottom of the milk container.
[0021] (5) Different lengths of extension sides are connected to different rings; different rings are replaced according to the actual use scenario. Attached Figure Description

[0027] Figure 1 The diagram shows a bottom view of the nozzle of the steam milk stick according to the first embodiment of the present invention. Figure 2 This diagram shows a front view of the nozzle of the steam milk stick according to the first embodiment of this utility model. (Combined with...) Figure 1 and Figure 2 As shown, this utility model discloses a nozzle for a steam milk stick.
[0028] The nozzle of the steam milk wand includes a cylindrical body 5 arranged vertically. A central outlet 1 and a side outlet 2 are formed at the outlet of the cylindrical body 5. The outlet of the cylindrical body 5 is located at the lower end of the cylindrical body 5.
[0029] In this design, a pressure plane 3 is formed on the outer side of the side outlet 2. Specifically, the lower end of the outer surface of the cylinder 5 is flattened to form the pressure plane 3, thereby reducing the cross-sectional area of the side outlet 2. Gas flows downwards inside the cylinder 5, along the pressure plane 3, and accumulates at the side outlet 2. The gas then flows downwards from the side outlet 2. Because of the large amount of accumulated gas, the gas has a longer flow path in the milk, preventing diffusion after entering the milk. The gas only diffuses at the bottom of the milk container, allowing it to reach a larger area at the bottom, thus improving the efficiency of frothing or heating.
[0030] The cross-sectional area of the cylinder 5 is larger than the sum of the cross-sectional areas of the middle opening 1 and the side outlet 2, which results in a faster gas flow rate when the gas inside the cylinder 5 flows out through the middle opening 1 and the side outlet 2. At the same time, the gas inside the cylinder 5 is divided into several streams that flow out from the middle opening 1 and the side outlet 2 respectively, which allows the gas to come into full contact with the milk and improves the efficiency of frothing or heating.
[0031] The outlet of the stamping cylinder 5 consists of a central opening 1 and side outlets 2 distributed outside the central opening 1. The central opening 1 and the side outlets 2 distributed outside the central opening 1 form the outlet structure of the stamping cylinder 5. There are no fewer than two sets of side outlets 2. The shape of the outlet structure is determined according to the specifications or usage scenarios of the steam milk stick, and can be straight, triangular, cross-shaped, or flower-shaped.
[0032] When the outlet structure is straight, there are two sets of outlet 2 on the corresponding side. When the outlet structure is triangular, there are three sets of outlet 2 on the corresponding side. When the outlet structure is cross-shaped, there are four sets of outlet 2 on the corresponding side. When the outlet structure is flower-shaped, there are five or more sets of outlet 2 on the corresponding side.
[0033] During the stamping process at the outlet of the cylinder 5, to ensure smooth gas flow from the cylinder 5 through the side outlet 2, the inner surface of the cylinder 5 forms an arc transition towards the side outlet 2. With reduced resistance, the gas flows out through the side outlet 2, resulting in a faster gas flow rate. As the gas transitions along the side outlet 2 to the pressure surface 3, it can accumulate smoothly.
[0034] An edge 11 is formed around the central opening 1, and the edge 11 corresponds to the side exit 2. The number of edge 11 corresponds to the number of side exit 2. For example, when there is one set of side exit 2, the number of edge 11 is one set. When there are multiple sets of side exit 2, the number of edge 11 is multiple sets equal to the number of side exit 2.
[0035] By forming the angle 11, when the gas inside the cylinder 5 flows out through the middle opening 1, the gas forms a corresponding angle shape and diffuses, increasing the contact area between the gas and the milk to achieve full contact and improving the efficiency of foaming or heating.
[0036] The pressure plane 3 is formed at intervals on each side outlet 2.
[0037] The gas flowing out of the side outlet 2, where no pressure plane 3 is formed, has a short flow path and does not contact the bottom of the milk container, thus diffusing within the milk. Conversely, the gas flowing out of the side outlet 2, where a pressure plane 3 is formed, has a long flow path and diffuses at the bottom of the milk container. This diffusion at different locations results in a wider range of gas action, allowing for a broader range of foaming or heating.
[0038] Side outlet 2 forms an extended edge 4 along the gas flow direction. The pressure plane 3 transitions to the extended edge 4. The extended edge 4 is welded to the cylinder 5 near the side outlet 2. The upper end of the extended edge 4 is connected to the cylinder 5, and the lower end of the extended edge 4 extends downward.
[0039] When the gas flows out from the side outlet 2, it transitions from the pressure plane 3 to the extended edge 4, which further extends the flow path of the gas. The gas has a greater impact force on the bottom of the milk container, a wider diffusion range, and a wider range for foaming or heating, thus further improving the efficiency of foaming or heating.
[0040] The gas flowing from the nozzle of the steam milk wand can be divided into multiple streams. The gas flows out from the cylinder 5 through the central opening 1, forming the first stream of gas that enters the milk. The gas flows out from the cylinder 5 through the side outlet 2, forming the second stream of gas that enters the milk. The gas flows from the cylinder 5 across the pressure surface 3 and accumulates with the gas from the side outlet 2, forming a third stream of gas that acts on the bottom of the milk container and diffuses. The accumulated gas continues to flow along the extended edge 4, which can amplify the impact force of the third stream of gas on the bottom of the milk container.
[0041] Second embodiment:
[0042] Figure 3 A bottom view of the nozzle structure of the steam milk stick according to the second embodiment of this utility model is shown. (Combined with...) Figures 1-3 As shown, the extension edge 4 is set on the ring 41, and the shape of the ring 41 matches the shape of the lower end of the outer surface of the cylinder 5. The upper end of the extension edge 4 is connected to the ring 41.
[0043] The ring 41 is fitted onto the outlet of the cylinder 5 from below. Pushing the ring 41 upwards locks it in place at the outlet. Pushing the ring 41 downwards removes both the ring 41 and the extension edge 4. Different rings 41 are connected to extension edges 4 of varying lengths. A longer extension edge 4 results in a greater impact force of the gas on the bottom of the milk container, while a shorter extension edge 4 results in a smaller impact force. Different rings 41 can be used depending on the specific application.
[0044] 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.
[0045] 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.
