[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as those commonly understood by those skilled in the art of the present invention. The terms used herein in the specification of the present invention are only for the purpose of describing specific embodiments and are not intended to limit the present invention.
[0029] See also Figure 1-Figure 4 The utility model discloses a foaming device, including a mixing seat 10, a liquid inlet conduit 20, a steam conduit 30 and a dewatering pipe 40. Specifically, a mixing chamber 11 and a guide channel 12 are provided in the mixing seat 10. One end of the mixing chamber 11 is an inlet end 111, and the other end of the mixing chamber 11 is a dewatering end 112. A first inlet port 121, a second inlet port 122 and a dewatering port are provided in the guide channel 12, and the dewatering port of the guide channel 12 is connected with the inlet end 111.
[0030] One end of the liquid inlet conduit 20 can be used to introduce liquid, and the other end of the liquid inlet conduit 20 is connected to the first introduction port 121. One end of the steam conduit 30 introduces steam, and the other end of the steam conduit 30 is connected to the second introduction port 122, and the steam conduit 30 can introduce steam into the guide channel 12 to form a negative pressure in the guide channel 12. After the negative pressure is formed in the guide channel 12, the liquid in the liquid inlet conduit 20 can be guided to be introduced from the first introduction port 121. In addition, the outlet pipe 40 is provided with an outlet channel 41, and the outlet pipe 40 is connected to the outlet end 112. After the outlet pipe 40 is connected to the outlet end 112, the outlet channel 41 can be connected to the outlet end 112.
[0031] On the basis of the above structure, when the foaming device of the utility model is used, the foaming device is applied to milk foaming production as an example for explanation:
[0032] When in use, the steam conduit 30 is connected to the steam outlet of the steam generator, the steam conduit 30 is connected to the second introduction port 122 of the guide channel 12 of the mixing seat 10, one end of the liquid inlet conduit 20 is connected to the milk tank, and the liquid inlet conduit 20 is connected to the first introduction port 121. After the steam is introduced into the guide channel 12, the air in the guide channel 12 can be taken away to make the guide channel 12 in a negative pressure state. At this time, the liquid inlet channel connected to the first introduction port 121 can suck the milk into the guide channel 12 and enter the mixing chamber 11 under the action of the steam. Since the steam is introduced into the outlet end 112 of the mixing chamber 11 through the guide channel 12 instead of directly entering the outlet channel 41 of the outlet pipe 40, the steam can form a steam vortex in the mixing chamber 11. The milk sucked into the liquid inlet conduit 20 can be fully mixed in the mixing chamber 11 and foamed, and then enter the outlet end 112, and then be discharged into the beverage through the outlet channel 41 of the outlet pipe 40.
[0033] The existing practice is to guide the steam and milk directly to the guide channel 12, and then directly guide them to the outlet channel 41 of the outlet pipe 40 through the guide channel 12 for outlet. In this way, the milk and steam are directly mixed and foamed in the outlet pipe 40, so that the milk and steam cannot be fully mixed, resulting in poor foaming effect. Therefore, in this embodiment, the outlet pipe 40 is connected to the outlet end 112 of the mixing chamber 11, and the guide channel 12 is connected to the inlet end 111 of the mixing chamber 11. In this way, there is a mixing chamber 11 between the guide channel 12 and the outlet channel 41 of the outlet pipe 40 to form a mixing space for steam and milk. After the steam enters the mixing chamber 11, it forms a vortex and is fully mixed with the milk for foaming.
[0034] Furthermore, a connecting pipe section 42 may be provided at the top of the outlet pipe 40, and the connecting pipe section 42 is connected to the outlet end 112. After the connecting pipe section 42 is inserted into the outlet end 112, the end surface of the connecting pipe section 42 is spaced from the inlet end 111, and the outer wall of the connecting pipe section 42 is sealed with the inner wall of the outlet end 112. A conducting channel 421 is provided in the connecting pipe section 42, and one end of the conducting channel 421 is connected to the mixing chamber 11, and the other end of the conducting channel 421 is connected to the outlet channel 41.
[0035] In this way, the outlet pipe 40 can be connected to the outlet end 112 of the mixing chamber 11 through the connecting pipe section 42, so that the connecting pipe section 42 is sealed and connected to the mixing chamber 11 of the mixing seat 10 in an inserting manner, and the connection is convenient. After such connection, the mixed steam and milk in the mixing chamber 11 can be mixed and foamed and then be led out to the outlet channel 41 of the outlet pipe 40 through the conducting channel 421, and the formed outlet path can also be a longer path formed by the conducting channel 421 and the outlet channel 41, so that the steam and milk can be fully foamed and then be led out.
[0036] Furthermore, a sealing ring 43 may be provided outside the connecting pipe section 42. After the connecting pipe section 42 is connected to the outlet end 112, the sealing ring 43 of the connecting pipe section 42 may be sealed with the inner wall of the outlet end 112, so that a seal is formed at the connection position between the connecting pipe section 42 and the outlet end 112 through the sealing ring 43.
[0037] Of course, a sealing ring 43 or a sealant may be provided on the inner wall of the outlet end 112, and a seal may be formed after the connecting pipe section 42 is connected to the mixing chamber 11. A seal may also be formed by filling the connecting pipe section 42 with a sealant after the connecting pipe section 42 is connected to the mixing chamber 11.
[0038] Furthermore, in order to facilitate the installation of the sealing ring 43, an annular groove can be provided on the outer surface of the connecting pipe section 42, and the sealing ring 43 can be installed in the annular groove. After the connecting pipe section 42 penetrates the outlet end 112 of the mixing chamber 11, the sealing ring 43 is sealed with the inner wall of the outlet end 112, and the sealing ring 43 is limited by the annular groove, thereby reducing the movement of the sealing ring 43 on the connecting pipe section 42. In particular, there will be a large impact force after the steam is introduced into the mixing chamber 11. If the sealing ring 43 does not have a limiting structure, it may move under the action of the impact after the steam is introduced, causing the sealing structure to loosen. Therefore, in this embodiment, the sealing ring 43 is limited by the annular groove, and the sealing structure is also more stable.
[0039] Furthermore, in the present embodiment, the above-mentioned conducting channel 421 is arranged corresponding to the guide channel 12, so that the steam portion derived from the guide channel 12 can correspond to the conducting channel 421. If the guide channel 12 is staggered with the conducting channel 421, after the steam is guided to the mixing chamber 11 through the guide channel 12, most of the steam will be blocked by the end wall of the connecting pipe section 42, so that the steam introduction force is dispersed, and the steam impulse acting on the conducting channel 421 is insufficient, so that the foaming mixture in the conducting channel 421 will be retained. Therefore, the present application makes the guide channel 12 correspond to the conducting channel 421, and the impulse formed during the steam introduction process can be aligned with the conducting channel 421, so as to flush out the foaming mixture in the conducting channel 421, and the extraction is easier and smoother.
[0040] Furthermore, a limiting portion may be provided outside the connecting pipe section 42, and the limiting portion abuts against the outer end face of the outlet end 112. After the connecting pipe section 42 penetrates into the outlet end 112 of the mixing chamber 11, due to the setting of the limiting portion, the connecting pipe section 42 cannot be fully extended into the mixing chamber 11. During the process of the connecting pipe section 42 extending, the limiting portion may abut against the end face of the outlet end 112. In this way, after the end face of the connecting pipe section 42 penetrates into the outlet end 112, it is spaced from the inlet end 111, and space may be reserved for mixing steam and milk.
[0041] More specifically, the above-mentioned limiting portion is an annular boss, which is arranged outside the connecting pipe section 42, so that after the connecting pipe section 42 extends into the outlet end 112, it can abut against the outlet end 112 in the circumferential direction, so that the limiting contact surface is large and the limiting structure is more stable.
[0042] Of course, the connecting pipe section 42 and the outlet end 112 of the mixing chamber 11 can also be connected by inserting the connecting pipe section 42 into the outlet end 112, and the limiting portion is formed by a step surface set in the conducting channel 421, depending on actual needs.
[0043] Furthermore, the foaming device further comprises a container shell 50, wherein a first chamber 51 and a second chamber 52 are provided in the container shell 50, the mixing seat 10 and the steam conduit 30 are installed in the first chamber 51, the first chamber 51 is provided with a steam inlet 511, the steam inlet 511 is connected to the steam conduit 30, so that the steam outlet of the steam generator can be connected to the steam inlet 511, and the steam can be guided to the steam conduit 30 through the steam inlet 511. A milk container can be placed in the second chamber 52, and the milk container can be put into or taken out of the second chamber 52 in a pulling manner, so as to facilitate the addition of milk. One end of the liquid inlet conduit 20 is connected to the milk container in the second chamber 52, and the other end of the liquid inlet conduit 20 extends into the first chamber 51 to be connected with the first introduction port 121, and the liquid inlet conduit 20 can guide the milk container to the first introduction port 121 and enter the guide channel 12, and mix with the steam to foam.
[0044] Of course, in this embodiment, milk foaming is used for explanation. In other cases, the foaming device can also be used for foaming other beverages. You can choose according to actual needs.
[0045] Embodiment 2,
[0046] A coffee machine includes a coffee machine body and a foaming device according to Embodiment 1. A steam generator is provided in the coffee machine body, and a steam conduit 30 can be connected to a steam outlet of the steam generator. In this way, after the coffee is made by the coffee machine, the coffee machine can be moved to the position of the outlet pipe 40 to receive milk foam exported by the outlet pipe 40 of the foaming device, so that a coffee drink with milk foam can be made.
[0047] When making coffee milk foam, the steam conduit 30 is connected to the steam outlet of the steam generator of the coffee machine, the steam conduit 30 is connected to the second inlet 122 of the guide channel 12 of the mixing seat 10, one end of the liquid inlet conduit 20 is connected to the milk tank, and the liquid inlet conduit 20 is connected to the first inlet 121. After the steam is introduced into the guide channel 12, the air in the guide channel 12 can be taken away to make the guide channel 12 in a negative pressure state. At this time, the liquid inlet channel connected to the first inlet 121 can suck the milk into the guide channel 12 and enter the mixing chamber 11 under the action of the steam. Since the steam is introduced into the outlet end 112 of the mixing chamber 11 through the guide channel 12 instead of directly entering the outlet channel 41 of the outlet pipe 40, the steam can form a steam vortex in the mixing chamber 11, and the milk sucked in by the liquid inlet conduit 20 can be fully mixed in the mixing chamber 11 and then foamed, and then enter the outlet end 112, and then be discharged into the coffee beverage through the outlet channel 41 of the outlet pipe 40.
[0048] It should be noted that when the foaming device has a container shell 50, the container shell 50 can be installed on the body of the coffee machine, and the steam inlet 511 of the first chamber 51 of the container shell 50 is connected to the steam outlet of the coffee machine. In addition, the other structures in this embodiment are the same as those in Example 1, and the working principle and effect are the same as those in Example 1, which will not be described in detail.
[0049] The technical means disclosed in the solution of the utility model are not limited to the technical means disclosed in the above-mentioned implementation mode, but also include technical solutions composed of any combination of the above technical features. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model, and these improvements and modifications are also regarded as the protection scope of the utility model.
