Description

Technical Field

[0001] The utility model is applied to the technical field of coffee machines, and particularly relates to a portable coffee machine structure. Background Art

[0002] A coffee machine is a tool for making coffee, which can heat and pressurize water and inject it into a sealed container, extract the coffee powder in the sealed container, and then extract coffee. Conventional coffee machines are large in size and inconvenient to carry out, so portable coffee machines are now developed in the market, such as the Chinese patent with publication number CN220800765U, which discloses a portable coffee machine structure, including a main body, a water cup, a heating component and a pump body are arranged in the main body, and the bottom of the main body is provided with a middle bottom cover and a sealing plate connected to the pump body, and a shower is arranged on the sealing plate, and the shower cooperates with the powder cup to extract liquid. In this scheme, the liquid is directly discharged through the powder cup structure, and the main body is usually inverted after the extraction is completed to prevent residual liquid from leaking and causing pollution. However, since the pressure provided by the pump body disappears after stopping work, and the outlet of the powder cup will also be connected to the outside atmosphere after inversion, the participating liquid is deposited on the main body, and there is a certain probability that the residual liquid will penetrate into the gap between the main body and the middle bottom cover, causing the internal circuit board to contact the liquid and malfunction. At the same time, the powder cup is at the bottom of the coffee machine and is easily contaminated when it comes into contact with other objects during use.

[0003] If a portable coffee machine structure with more reliable internal circuit board protection and less prone to contaminating the powder cup can be provided to address the shortcomings of this solution, the above problems can be well solved. Utility Model Content

[0004] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a portable coffee machine structure with more reliable protection of the internal circuit board and less prone to contamination of the powder cup.

[0006] It can be seen from the above scheme that the middle bottom cover is isolated from the bottom of the main body by the sealing gasket on the connecting ring, and the first annular protrusion is provided at the same time, wherein the first annular protrusion on the upper surface is sealed with the main body, and the first annular protrusion on the lower surface is sealed with the middle bottom cover, and the first annular protrusion is pressed when locked to prevent liquid from invading, thereby ensuring that the residual coffee liquid can be effectively isolated outside the main body in case of improper operation or inversion, and effectively protecting the electronic components such as the circuit board and battery in the main body from being contaminated by liquid and causing short circuit.

[0007] A preferred solution is that a first through hole and a plurality of connecting screws are provided on the inner side of the main body, and the connecting screws pass through the first through hole from the inner side of the main body and are threadedly connected to the connecting ring, and a second through hole cooperating with the connecting screw is provided on the sealing gasket, and a second annular protrusion is provided on the edge of the second through hole.

[0008] A preferred solution is that the sealing gasket includes an annular portion, the upper and lower edges of the annular portion are provided with outwardly extending extension portions, the first annular protrusion is respectively located on the contact surfaces of the two extension portions, the annular portion is adapted to the inner diameter of the mounting portion on the connecting ring, and the mounting portion is provided with a plurality of threaded holes that correspond one-to-one with the connecting screws.

[0009] A preferred solution is that a potting glue that seals with the connecting screw is provided at the first through hole.

[0010] A preferred solution is that the portable coffee machine structure also includes a bottom cup, the powder cup assembly includes a locking ring and a cup body, a sealing damping ring cooperating with the cup body is provided on the outer side of the locking ring, and exhaust ports are provided at intervals on the sealing damping ring.

The main body 1 is used to set a container and heat the water in the container through the internal heating component, and then pressurize the hot water through the pump body 5 and inject it into the powder cup assembly 4 filled with coffee powder. After the powder cup assembly 4 is filled with coffee powder, its upper end is connected to the main body 1, and the shower assembly 3 is sealed with the upper end of the powder cup assembly 4. The shower assembly 3 is connected to the liquid outlet of the pump body 5, and the liquid is drained and diverted through the internal cavity, and then the high-pressure hot water is output to the coffee powder through the several small liquid outlets on the lower surface. The high-pressure hot water penetrates the coffee powder under the action of pressure and penetrates toward the liquid outlet of the powder cup assembly 4, and finally forms the extracted coffee liquid and outputs it from the liquid outlet. The connecting ring 6 is used to connect the powder cup assembly 4 and ensure that there is enough locking pressure between the powder cup assembly 4 and the shower assembly 3 to ensure sealing. At the same time, the connecting ring 6 cooperates with the middle bottom cover 2 to isolate the liquid outlet of the pump body 5, on the one hand, to ensure that the liquid between the middle bottom cover 2 and the shower assembly 3 will not leak to the outlet of the pump body 5 and the middle bottom cover 2, and on the other hand, to ensure that the liquid accumulated between the outlet of the pump body 5 and the middle bottom cover 2 due to pressure or improper operation will not invade the main body 1, thereby ensuring that the circuit structure and components of the main body 1 can work more safely and reliably during use.
