[0002] Traditional coffee machines typically use no or a single heating element to heat the liquid entering the brewing unit to achieve coffee extraction. However, in actual use, water vapor and condensation easily accumulate inside the brewing unit, especially during continuous operation or in high-humidity environments. This residual moisture can not only affect the flavor quality of the coffee but also seep into the machine, causing corrosion or short circuit risks to electronic components, circuit boards, or other sensitive parts, thereby reducing the reliability and lifespan of the device. Summary of the Invention

[0003] Based on this, it is necessary to provide a coffee machine to address the problem that traditional coffee machines have residual moisture inside the brewing component, which affects the flavor quality of the coffee and penetrates into the machine, reducing the reliability and service life of the equipment.

[0005] The present application discloses a coffee machine, which can heat the liquid entering the brewing chamber through the arrangement of a first heating component to ensure the temperature required for coffee extraction. By placing the second heating component in close contact with or adjacent to the brewing component, auxiliary heating can be performed on the periphery of the brewing chamber, effectively reducing the accumulation of water vapor and condensed water. This design can actively convert residual water vapor into fast-flowing steam for discharge. The steam can be discharged from the exhaust hole or steam pipe to avoid moisture retention affecting the flavor of the coffee, while keeping the interior of the coffee machine dry, reducing the risk of corrosion or short circuit of internal components due to moisture, and improving the reliability and service life of the equipment. By having the first mounting cavity and the second mounting cavity located on both sides of the brewing chamber, respectively, the distribution of the heating components is made more reasonable, which not only ensures uniform heat transfer, but also avoids local overheating or uneven temperature problems caused by unilateral heating, thereby improving the quality of coffee extraction.

[0071] The present application discloses a coffee machine, which can heat the liquid entering the brewing chamber 201 by setting the first heating component 3 to ensure the temperature required for coffee extraction. By setting the second heating component 5 in close contact with or adjacent to the brewing component 2, the periphery of the brewing chamber 201 can be auxiliary heated, effectively reducing the accumulation of water vapor and condensed water. This design can actively convert residual water vapor into fast-flowing steam for discharge. The steam can be discharged from the exhaust hole or steam pipe to avoid moisture retention affecting the coffee flavor. At the same time, it keeps the interior of the coffee machine dry, reduces the risk of corrosion or short circuit of internal components caused by moisture, and improves the reliability and service life of the equipment. By locating the first installation cavity 102 and the second installation cavity 103 on both sides of the brewing chamber 101 respectively, the distribution of the heating components is more reasonable, which not only ensures uniform heat transfer, but also avoids local overheating or temperature unevenness caused by unilateral heating, thereby improving the quality of coffee extraction.

The first stopper 24122 and the second stopper 24123 are both disposed on the powder discharge housing 24121 and are disposed opposite each other. The powder discharge housing 24121, the first stopper 24122, and the second stopper 24123 together form the powder discharge channel 205. The relative arrangement of the first stopper 24122 and the second stopper 24123 forms a precise powder-residue guide channel. The enclosed powder discharge channel 205 effectively constrains the movement trajectory of the powder, forming a physical barrier to prevent lateral dispersion of powder residue, allowing the powder residue to accurately fall to a designated collection location, thereby improving powder residue cleaning efficiency.

[0079] like Figure 6 As shown, in addition to the features of the above-mentioned embodiment, this embodiment further defines: the brewing shell body 2411 is provided with a powder discharge slope 206. One side of the powder discharge slope 206 extends toward the end of the brewing shell body 2411 where the powder discharge port 203 is located, and the other side of the powder discharge slope 206 extends toward the powder discharge channel 205. The provision of the powder discharge slope 206 forms a continuous transition surface, guiding the powder residue to naturally slide from the powder discharge port 203 to the powder discharge channel 205, ensuring the continuity of the powder residue conveying path. The inclined surface also prevents accumulation on a flat surface, reducing the adhesion of powder residue.

[0080] In addition to the features of the above-described embodiment, this embodiment further provides that: the mounting housing 1 is provided with a slag storage chamber; one end of the powder discharge channel 205 extends toward the end of the brewing shell body 2411 provided with the powder discharge port 203; and the other end of the powder discharge channel 205 extends toward the slag storage chamber. Because the powder discharge channel 205 extends toward the slag storage chamber or is directly connected to the slag storage chamber, powder residue scraped from the powder discharge port 203 can be directly transported to the slag storage chamber for collection, thereby preventing powder residue from splashing and causing tedious subsequent cleaning.

[0081] like Figure 6 As shown, in addition to the features of the above embodiment, this embodiment further provides that: the powder outlet channel 205 is tilted relative to the brewing shell body 2411. By tilting the powder outlet channel 205 relative to the brewing shell body 2411, gravity can be used to promote the natural sliding of powder residue, reduce conveying resistance, improve powder residue discharge efficiency, and avoid or reduce powder residue adhesion.

[0082] like Figure 5-7 and Figure 13As shown, in addition to the features of the above embodiment, this embodiment further defines that: the powder outlet 2412 is located on the side of the brewing shell body 2411. The powder outlet 2412 is located on the side of the brewing shell body 2411, which facilitates the collection of powder residue and facilitates subsequent cleaning or maintenance.

[0083] like Figure 5-7 and Figure 13 As shown, in addition to the features of the above embodiment, this embodiment further defines that: the powder outlet 2412 is integrated with the brewing shell body 2411. By integrating the powder outlet 2412 with the brewing shell body 2411, the number of parts and assembly steps are reduced, which can effectively save costs.

[0084] like Figure 11 As shown, in addition to the features of the above embodiments, this embodiment further defines that: the brewing support 21 includes a support body 211 and a limit block 212, the support body 211 is arranged on the mounting shell 1 and is located in the brewing cavity 101, the limit block 212 is arranged on the support body 211, the limit buckle 243 can be against or separated from the limit block 212, when the limit buckle 243 is against the limit block 212, the brewing shell 241 can move relative to the push cylinder structure 242, and when the limit buckle 243 is separated from the limit block 212, the brewing shell 241 and the push cylinder structure 242 can move together relative to the brewing support 21. The limiting buckle 243 can be pressed against the brewing support 21 so that the brewing support 21 limits the freedom of the push-cylinder structure 242, so that the brewing shell 241 can move relative to the push-cylinder structure 242 to adjust the depth of the brewing chamber 201, which is convenient for releasing powder; it can also be separated from the brewing support 21 so that the brewing support 21 and the push-cylinder structure 242 can move together, which is convenient for adjusting the distance between the whole and the first brewing component 22, thereby adjusting the powder releasing space and making the powder releasing operation convenient.

When the component 6 rotates relative to the second brewing component 24, the scraper structure 63 has at least a first position and a second position. When the second brewing component 24 moves in a first direction, the powder scraping component 6 can rotate from the first position to the second position, and when the second brewing component 24 moves in a second direction, the powder scraping component 6 can rotate from the second position to the first position. The first and second directions are opposite. The brewing support 21 is provided with a transmission cavity 207. A first rib 213 is formed on the cavity wall of the transmission cavity 207. When the powder scraping component 6 moves from the first position to the second position, the transmission structure 62 abuts against the first rib 213. The arrangement of the powder scraping component 6 enables powder residue at the powder discharge port 203 to be cleaned. The arrangement of the first rib 213 allows the powder scraping component 6 to abut against the transmission structure 62 of the first rib 213 after the second brewing component 24 moves to the corresponding position. The portion of the transmission structure 62 abutting against the first rib 213 is arc-shaped, allowing the powder scraping component 6 to rotate under the abutment of the first rib 213. This design enables the powder scraping component 6 to automatically rotate to scrape powder and return to its original position after the second brewing component 24 moves to the corresponding position, which has a high degree of automation.
