[0032] The following describes several preferred embodiments of the utility model with reference to the drawings in the specification, so that the technical content is clearer and easier to understand.

The size and thickness of each component shown in the drawings are arbitrarily shown, and the utility model does not limit the size and thickness of each component. In order to make the illustration clearer, the thickness of the components is appropriately exaggerated in some places in the drawings.

[0034] like Figure 1-2 As shown, according to the utility model, the condenser includes a condensing core rod 100 and a hose 200. A spiral flow channel 101 is provided on the condensing core rod 100.

The steam generated when making coffee in the coffee machine enters the condenser through the inlet 205 of the hose 200, is decelerated when passing through the spiral flow channel 101 of the condensing core rod 100, and the droplets condense into liquid water, and flow out from the outlet 206 of the hose 200 after passing through the first bending portion 202 and the second bending portion 203.

[0035] The utility model adopts a condensing core rod with a spiral flow channel inserted into a hose to form a condenser. Although this structure has limited steam processing capacity and cannot be used in situations where a large flow of steam is required, it is completely sufficient for the steam condensation of a coffee machine. It does not require screw tightening or ultrasonic welding, and does not require the use of sealing rings, thereby greatly reducing the risk of water leakage and manufacturing costs.

Among them, the high-low pressure relief joint includes an outlet component 1 and an inlet component 2.

A first internal thread column 25 is arranged outside the first pressure relief pipe 23, and a second internal thread column 26 is arranged outside the second pressure relief pipe 24. After assembly, the first pressure relief pipe 23 of the inlet component 2 is assembled into the first semicircular flange 15, and the second pressure relief pipe 24 is assembled into the second semicircular flange 16 of the outlet component 1, and the outlet component 1 and the inlet component 2 are fixedly assembled together by passing through the first bolt assembly hole 17 and the second bolt assembly hole 18 and fastening the bolts in the first internal thread column 25 and the second internal thread column 26. A first one-way valve is arranged inside the first pressure relief pipe 23, and the first one-way valve includes a first valve head 3 and a first spring 4, and the first spring 4 is installed on the first guide column 13, and the first valve head 3 faces the first inlet 21.

It should be understood that ordinary technology in the field can make many modifications and changes according to the concept of the utility model without creative work.
