Background technology
The sucking device of existing coffee machine, comprise a rubber base, the steam port being provided with hybrid chamber in this rubber base and communicate with this hybrid chamber, milk outlet, enter milk mouth and enter with this air scoop that milk mouth communicates, steam port and milk outlet are point-blank, be inserted with outlet in steam port, in milk outlet, be inserted with milk drain tube, enter in milk mouth and be inserted with milk feeding pipe, outlet is circumscribed with metal tube by screw thread, and the aperture of the outlet communicated with the pipeline of this metal tube diminishes to hybrid chamber direction.Steam enters in the pipeline of metal tube, through the pipeline of outlet, because the aperture of outlet diminishes, the flow velocity of steam increases, vacuum area is formed at the outer end spaces of outlet, milk sucks from milk feeding pipe, and air enters from air scoop, like this, hybrid chamber is entered after milk and air mixing, under the effect of the vapor stream sprayed from outlet, enter milk drain tube, air out and the mixture of milk just form milk and have steeped.
But, the metal tube that existing sucking device is communicated with steam links together with the mode that the outlet being communicated with hybrid chamber is threaded connection, therefore, be difficult to the axiality ensureing metal tube and outlet, after steam enters from metal tube, can spin in hybrid chamber from outlet steam out, on the one hand, can not ensure that the complete direct projection of steam gets off to enter milk drain tube, on the other hand, cause milk can not enter hybrid chamber from milk tub swimmingly.
Utility model content
The technical problems to be solved in the utility model is the present situation for prior art, provides a kind of and ensures that steam can penetrate by straight line, the sucking device of the coffee machine that vacuumizing effect is good.
The utility model solves the problems of the technologies described above adopted technical scheme: a kind of sucking device of coffee machine, comprise a rubber base, the steam port being provided with hybrid chamber in this rubber base and communicating with this hybrid chamber, milk outlet and enter milk mouth, described steam port and described milk outlet are point-blank, outlet is inserted with in described steam port, milk drain tube is inserted with in described milk outlet, describedly enter to be inserted with milk feeding pipe in milk mouth, described outlet is circumscribed with metal tube by screw thread, it is characterized in that: the shower nozzle also comprising the pipe end being inserted into described outlet, described metal tube and described outlet link together by this shower nozzle, the spray-hole that aperture diminishes is offered in described shower nozzle, the center line of this spray-hole and the center line of described metal tube are point-blank.
As improvement, described shower nozzle is inserted into the end of described metal tube, and the end face of described shower nozzle and described metal tube offsets, and shower nozzle is inserted into the end of metal tube, is convenient to processing, meanwhile, ensure that the axiality of shower nozzle and metal tube.
Improve again, between the inwall of described shower nozzle and described metal tube, be provided with sealing ring, prevent steam from gas leakage in the screw thread seam between metal tube and outlet, avoid the tolerance of steam not enough, ensure out that milk is smooth and easy.
Improve again, the sucking device of described coffee machine also comprises a metal sleeve, it is interior and relative with described milk drain tube that described metal sleeve assigns into described rubber base, the center line of described metal sleeve, the center line of described metal tube and the center line of described milk drain tube are point-blank, because rubber base adopts elastomeric material to make, rubber base to go out milk end material softer, under the impact of steam, the center of milk outlet can offset, cause milk not smooth, by arranging metal sleeve, improve the intensity milk end of rubber base, ensure that the milk in hybrid chamber can penetrate from the center line of milk drain tube completely, be unlikely milk dropping fire everywhere, improve the aesthetic property milk.
Improve, described metal sleeve is provided with aperture to the bellmouth going out milk direction and diminish towards one end of described hybrid chamber, by arranging bellmouth, the milk be convenient in hybrid chamber is collected again.
Improve again, described rubber base also offer air scoop, described air scoop be positioned at described steam port other and described enter milk mouth communicate, realize milk and can mix with air before entering hybrid chamber.
Compared with prior art, owing to the utility model has the advantage of: by arranging shower nozzle, overcome virgin metal pipe and bring the defect of axiality with being threaded of outlet, ensure that the center line of metal tube can aim at the center line with milk drain tube, make steam from metal tube out after, direct projection can enter milk drain tube, the problems affect such as burr, overlap avoided due to rubber base goes out direction and the speed of milk.

Detailed description of the invention
Below in conjunction with accompanying drawing embodiment, the utility model is described in further detail.
As shown in Fig. 1 to 5, the sucking device of the coffee machine in this enforcement, comprises a rubber base 6, outlet 4, metal tube 1, milk drain tube 8, milk feeding pipe 7, shower nozzle 3, sealing ring 2 and metal sleeve 5 etc.
Wherein, the steam port 62 being provided with hybrid chamber 61 in this rubber base 6 and communicating with this hybrid chamber 61, air scoop 65, milk outlet 63 and enter milk mouth 64, steam port 62 and milk outlet 63 are point-blank, air scoop 65 be positioned at steam port 62 other with enter milk mouth 64 and communicate, realize milk to mix with air before entering hybrid chamber 61, steam port 62 is inserted in outlet 4, milk outlet 63 is inserted in milk drain tube 8, be inserted in milk feeding pipe 7 into milk mouth 64, outlet 4 is circumscribed with metal tube 1 by screw thread, shower nozzle 3 is inserted into the pipe end of outlet 4, metal tube 1 and outlet 4 link together by this shower nozzle 3, the spray-hole 31 that aperture diminishes is offered in shower nozzle 3, the center line of this spray-hole 31 and the center line of metal tube 1 are point-blank.
