The first feature "below", "below" and "below" the second feature can be that the first feature is directly below or obliquely below the second feature, or it only means that the horizontal height of the first feature is less than that of the second feature.

[0021] The application will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] Referring to Figures 1-5 As shown in the drawings, the application discloses a milk foam blocking device, which comprises a base 1, a milk inlet tee joint 2, a milk suction tee joint 3 and an air inlet plug 4. The milk inlet tee joint 2 and the milk suction tee joint 3 are both connected to the base 1. A first communication port 31 of the milk suction tee joint 3 is in communication with a milk foam outlet 11 on the base 1. A second communication port 32 of the milk suction tee joint 3 is used to be connected to a steam nozzle in a coffee machine body. An air inlet port 21, a milk inlet port 22 and a milk outlet port 23 are arranged on the milk inlet tee joint 2 and are in communication with each other. A third communication port 33 of the milk suction tee joint 3 is in communication with the milk outlet port 23. The milk foam blocking device further comprises an air inlet assembly 5. An air outlet end of the air inlet assembly 5 is connected to the air inlet port of the milk inlet tee joint 2. An air inlet end of the air inlet assembly 5 is connected to the air inlet plug 4. The air inlet plug 4 is arranged above the milk inlet tee joint 2 and is away from the air inlet port 21 of the milk inlet tee joint 2 through the air inlet assembly 5.

[0023] The air inlet assembly 5 comprises a joint fitting 51. An inner portion of the joint fitting 51 is provided with a cavity 511. A bottom portion of the joint fitting 51 is provided with an air outlet nozzle 512 which is in communication with the cavity 511. The air outlet nozzle 512 forms the air outlet end of the air inlet assembly 5. A top portion of the joint fitting 51 is provided with an air inlet nozzle 513 which is in communication with the cavity 511. The air inlet nozzle 513 forms the air inlet end of the air inlet assembly 5. The air outlet nozzle 512 is inserted into the air inlet port 21 on the milk inlet tee joint 2 and is circumferentially sealed with the air inlet port 21. The air inlet plug 4 is connected to the air inlet nozzle 513. After the air inlet assembly is used, even if milk enters the joint fitting through the air outlet nozzle, the milk can be temporarily stored in the cavity, so that the air inlet plug can be effectively prevented from being blocked by the milk.

[0024] The air outlet nozzle 512 is horizontally staggered with the air inlet nozzle 513. After this structure is used, even if milk enters the cavity through the air outlet nozzle, the milk can be further prevented from surging back to the air inlet nozzle, so that the air inlet plug can be further prevented from being blocked by the milk.

[0025] An inner bottom portion of the cavity 511 forms a funnel-shaped structure which is large at the top and small at the bottom. After this structure is used, if milk enters the cavity through the air outlet nozzle, the milk can be more smoothly backflowed to the milk inlet tee joint due to the funnel-shaped structure of the inner bottom portion of the cavity.

[0026] A cutting angle surface 514 is arranged on a lower end of the air outlet nozzle 512. After this structure is used, if milk surges back to the cavity through the air outlet nozzle, the air outlet nozzle can more smoothly drain the milk from the cavity back to the milk inlet tee joint under the action of the cutting angle surface.

[0027] The inner circumferential wall of the air inlet 21 is provided with an annular rib 211 which is tightly sealed with the outer circumferential wall of the air outlet nozzle 512. After the air outlet nozzle is inserted into the air inlet of the milk inlet tee joint, the air outlet nozzle can be tightly sealed with the inner wall of the air inlet under the action of the annular rib, i.e. the sealing effect between the air outlet nozzle and the inner circumferential wall of the air inlet can be improved.

[0028] The air inlet assembly 5 further comprises an air inlet pipe 52. The air inlet nozzle 513 is inserted into and circumferentially sealed with one end of the air inlet pipe 52, and the air inlet plug 4 is inserted into the other end of the air inlet pipe 52. The air inlet pipe can further prolong the air inlet passage between the air inlet plug and the air inlet of the milk inlet tee joint, thereby further avoiding the backflow of milk to the air inlet plug and blocking the air inlet plug.

[0029] The joint fitting 51 comprises a seat body 515 and a cover body 516. The seat body 515 is fixed on the base 1, and the cover body 516 is fixed on the seat body 515 in a circumferential sealing manner. The cavity 511 is formed between the cover body 516 and the seat body 515. The air outlet nozzle 512 is vertically arranged at the bottom of the seat body 515, and the air inlet nozzle 513 is vertically arranged at the top of the cover body 516. After the seat body and the cover body are assembled, the cavity can be conveniently formed between the cover body and the seat body.

[0030] The above is only a specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed in the present application, which should be covered in the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
