DETAILED DESCRIPTION

[0029] The specific implementation of the present invention is described below with reference to the accompanying drawings. In order to fully understand the present invention, many details are described below, but for those skilled in the art, the present invention can be implemented without these details.

[0030] Embodiment 1:

[0031] Reference Figures 1 to 3 A steam milk frothing machine comprises a frothing device 1, wherein the frothing device 1 comprises a mounting plate 11 and a sealing plate 12, wherein the mounting plate 11 is provided with a channel groove 111 and a mixing groove 112 which are interconnected, wherein the sealing plate 12 is detachably arranged on the mounting plate 11, and is sealed and matched with the channel groove 111 and the mixing groove 112 to form a feeding channel and a mixing chamber; a steam inlet 13, a milk inlet 14 and an air inlet 15 are arranged in the feeding channel, and a milk frothing outlet 16 is arranged in the mixing chamber. During operation, high-pressure steam, milk and air enter the feeding channel and are mixed in the mixing chamber, thereby heating the milk and frothing it to form a set milk froth. When the frothing device 1 needs to be cleaned, the sealing plate 12 can be removed from the mounting plate 11, thereby opening the feeding channel and the mixing chamber, thereby facilitating a thorough cleaning of the mounting plate 11 and the sealing plate 12, effectively reducing the difficulty of cleaning the frothing device 1, and improving the cleaning effect of the frothing device 1.

[0032] Reference Figures 2 to 8Preferably, the channel groove 111 is a first recessed portion provided on the mounting plate 11, and the mixing groove 112 is a second recessed portion provided on the mounting plate 11. The outer peripheral edges of the first recessed portion and the second recessed portion are both provided with a convex edge 113 that abuts against the sealing plate 12. During installation, the surface of the sealing plate 12 abuts against the convex edge 113 to ensure complete sealing. The sealing plate 12 is preferably a soft rubber with a certain hardness. During design, the sealing interference amount can be adjusted according to the hardness of the sealing plate 12, and the structure of the convex edge 113 can be reasonably designed accordingly. In order to facilitate installation and disassembly, the Shore hardness of the sealing plate 12 selected in this embodiment is 50°, the sealing interference amount of the sealing plate 12 is 0.3mm, and the cross section of the convex edge 113 is designed to be stepped. Of course, in other embodiments, the convex edge 113 can also be provided on the sealing plate, that is, the convex edge 113 that abuts against the outer peripheral edges of the first recessed portion and the second recessed portion is provided on the sealing plate 23.

[0033] Reference Figure 3 and Figure 4 The feed channel (i.e., the channel groove 111) includes a head section and a tail section connected to each other, the steam inlet 13 is arranged in the head section, and the milk inlet 14 and the air inlet 15 are arranged in the tail section. Preferably, the front end of the head section is a U-shaped structure, the rear end of the head section is a gradually contracting trumpet-shaped structure, and the tail section is a gradually expanding trumpet-shaped structure. Such a design makes the diameter of the feed channel change regularly along the feeding direction, thereby meeting the requirements of the Venturi effect. In addition, in order to ensure that the high-pressure steam, milk and air are fully mixed and reacted in the mixing chamber, the depth of the mixing groove 112 should be greater than the depth of the channel groove 111. During operation, the high-pressure steam enters the feed channel with a changing diameter from the steam inlet 13, forming a Venturi effect, sucking milk and air into the channel from the milk inlet 14 and the air inlet 15 respectively, and rushing to the mixing chamber to foam the milk, and finally flowing out from the milk foam outlet 16. It can be seen that a reasonable design of the structure of the channel groove 111 and the mixing groove 112 is helpful to improve the frothing effect of the frother 1, so that the frothed milk is denser.

[0034] Reference Figures 1 to 6The mounting plate 11 is provided with a steam inlet 13 and a milk inlet 14 in the channel groove 111, and is provided with a steam pipe 17 and a liquid suction pipe 18 connected to the steam inlet 13 and the milk inlet 14 respectively; the mounting plate 11 is provided with a notch at the rear end of the channel groove 111 to form an air inlet 15.

In order to simplify the production process of the sealing plate 12 and improve the cleaning efficiency, in this embodiment, the steam inlet 13, the milk inlet 14 and the air inlet 15 are centrally arranged on the mounting plate 11, and the area C where the sealing plate 12 and the channel groove 111 abut against each other is designed as a plane structure. Of course, in other embodiments, the steam inlet 13, the milk inlet 14 and / or the air inlet 15 can also be flexibly designed on the sealing plate 12.

[0035] Reference Figures 1 to 3 as well as Figures 6 to 8 The sealing plate 12 is provided with a milk foam outlet 16 and a liquid outlet pipe 19 connected to the milk foam outlet 16. In order to facilitate the smooth outflow of the whipped milk foam and prevent the milk foam from flowing back or remaining in the frother 1, the liquid outlet pipe 19 is designed to be inclined downward. In this embodiment, the inclination angle of the liquid outlet pipe 19 is preferably 10°. In other embodiments, as long as the smooth discharge of the milk foam can be ensured, the liquid outlet pipe 19 can also be arranged in other ways such as vertically downward. In order to improve the sealing performance of the mixing chamber, an annular boss 121 that abuts against the side wall of the mixing groove 112 can be provided on the sealing plate 12. In addition, in order to improve the assembly accuracy of the mounting plate 11 and the sealing plate 12, mutually matching positioning holes 114 and positioning columns 122 can also be provided.
