Summary of the invention

Technical problem to be solved in the utility model is that a kind of generation milk froth device of beating milk froth and going out the hot water handoff functionality that has is provided at the prior art present situation.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this is used to produce the device of milk froth, mainly comprise a main body, body interior is provided with the negative pressure cavity that connects, steam channel, the milk passage, air duct and steam-milk-air mixture passage, corresponding steam channel, the inlet of milk passage and steam-milk-air mixture passage is equipped with the steam jet that is connected with steam pipe respectively, milk pipet and foam jet is characterized in that also being equipped with on the described main body switching device that optionally opens or closes milk passage and air duct.

Described body interior has a milk passage and air duct to be communicated with the common-use tunnel of negative pressure cavity jointly; Described switching device comprises that one is assemblied in the knob on the main body, the cross through hole that the front portion of knob has a two to run through, and cross through hole two open ends and this common-use tunnel bore are complementary, to open or close this common-use tunnel by turning knob.

One passage that can supply air to enter is arranged on the described knob, and the cross through hole of this passage on knob connects negative pressure cavity, and forms described air duct.

Be processed with and the vertical blind hole that be communicated with vertical with cross through hole on the described knob, vertically the opening of blind hole seal with a chock plug, and the sidepiece of knob has an aperture, and the vertical blind hole of extension connection, and constitutes the described passage that supplies air to enter.

Compared with prior art, advantage of the present utility model is: the utility model is by being provided with a rotary switch on main body, switch inlet channel by turning knob, and the switching that reaches the air exercise milk froth and go out hot water function, with in the time will using hot water, forward knob the position of hot water to, the restriction air-water mixture flows out from air duct and milk passage, and adopts simple in structure, the good reliability, easy to operate of rotary switch.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

In conjunction with Fig. 1-shown in Figure 6, the device that the utility model produces milk froth mainly comprises a main body 1 and a switching device, wherein body interior is provided with negative pressure cavity 11, steam channel 13, milk passage 12, air duct and steam-milk-air mixture passage 14, and each passage all is communicated with described negative pressure cavity 11.The outer end of described steam channel 13, milk passage 12 and steam-milk-air mixture passage 14 is respectively steam inlet, milk inlet and air-milk-vapour mixture outlet, wherein the steam inlet is positioned at the upper end of main body, steam jet 4 is housed on it, is connected with steam pipe 3 on the nozzle.Milk inlet is positioned at the sidepiece of main body 1, and milk pipet 2 is housed on it.Air-milk-vapour mixture outlet is positioned at the lower end of main body, foam jet 5 is housed.And the air duct of this device is not to be directly arranged on the main body, and is provided in a side of on the knob 6 that constitutes switching device.

Described switching device is assemblied on the main body 1, is to be used for optionally opening or closing milk passage and air duct.This switching device mainly is made of a knob 6, and the profile of this knob 6 is roughly T-shaped, cross through hole 61 that a two runs through is arranged and perpendicular to vertical blind hole 62 of this through hole on it, and two holes are communicated with, and vertically the oral area of blind hole seals with a cylindrical plag 7.The sidepiece of knob has an aperture 63, is the inlet of air duct, and aperture extends internally and communicates with cross through hole 61 through vertical blind hole 62, makes the air duct of the tunnel-shaped cost device between aperture 63 and the negative pressure cavity 11.This passage has a common common-use tunnel 15 that is communicated with negative pressure cavity with milk passage 12, and the two open ends 64 of cross through hole is complementary with these common-use tunnel 15 bores on the knob.When knob 6 forwarded the position 8 of beating milk froth to, cross through hole 61 was parallel with common passage 15 during use, and passage is opened, as shown in Figure 1 and Figure 2; When knob 6 forwarded out the position 9 of hot water to, the two open ends 64 of cross through hole was left common-use tunnel 15 on the knob 6, makes pathway closure, as shown in Figure 3, Figure 4.Outside main body 1, indicate the switch flag of beating milk froth and going out hot water function, as shown in Figure 6.

Its operation principle is as follows: in the time will beating milk froth, knob 6 is forwarded to the position 8 of beating milk froth, steam by steam jet 4 ejections forms negative pressure space between steam jet and body, utilize atmospheric pressure that milk is pressed into negative pressure cavity 11 by milk pipet 2 and the air aperture 63 by the knob sidepiece, form steam, milk, Air mixing and produce the milk froth of many exquisitenesses at negative pressure cavity 11, can be used to make Italian type cappuccino coffee.In the time will using hot water, forward out knob the position 9 of hot water to, switch to this position and can prevent that air-water mixture from flowing out from air duct and milk passage.
