Description

Technical Field

[0001] This utility model relates to the field of coffee machines, and more particularly to a dual-voltage boiler structure for coffee machines. Background Technology

[0002] Coffee is a popular beverage, and making it requires a coffee machine. Current coffee machines are typically plugged in and fixed in one location, which limits their usability. Users need to find a new location with power when they need to move the machine. Some existing coffee machines are repositionable, but these usually use an external power source. However, if the external power source is unavailable, the machine will not function properly. Neither of these two types of coffee machines can simultaneously meet the needs of both mobile and fixed-location use, significantly reducing user convenience. Utility Model Content

The boiler structure 2 is housed within the coffee machine body 1 and is used to heat water flowing through the coffee machine. The boiler structure 2 includes a boiler shell 21. A DC heating element 22 and an AC heating element 23 are arranged within the boiler shell 21. The DC heating element 22 and the AC heating element 23 are used for power supply. The DC heating element 22 can withstand a voltage of 12V-20V. The AC heating element 23 can withstand a voltage of 100V-240V; at least one interface assembly 24 is arranged on the boiler shell 21; the interface assembly 24 includes a DC interface 241 and an AC interface 242; the DC interface 241 is connected to the DC heating element 22, and the AC interface 242 is connected to the AC heating element 23; a water pipe 25 is also provided inside the boiler shell 21, and the two ends of the DC heating element 22 and the AC heating element 23 are respectively connected to the DC interface 241 and the AC interface 242; the water pipe 25 is arranged in a ring outside the DC heating element 22 and the AC heating element 23; The water pipe 25 is heated by an AC heating tube 23 or a DC heating tube 22 after being energized. When the current passes through the DC heating tube 22 or the AC heating tube 23, the DC heating tube 22 or the AC heating tube 23 will heat up, and then transfer the heat to the water pipe 25. Subsequently, the water pipe 25 starts to work. Because the water pipe 25 is arranged in a ring, it can perform heating work better. By setting up a boiler structure 2, it is possible to use two different power supply methods, AC or DC. The water pipe 25 is heated after being powered by AC heating tube 23 or DC heating tube 22, which improves the safety of the product.

[0028] The interface component 24 is arranged on the opposite side of the boiler shell 21. The opposite side arrangement makes one end of the interface component 24 a positive electrode and the other end a negative electrode, which allows current to pass through better and can also better fix the AC heating tube 23 and the DC heating tube 22.

[0029] The AC interface 242 is longer than the DC interface 241; the AC heating tube 23 is longer than the DC heating tube 22, and two different lengths are provided for easy differentiation during installation.

[0030] At least one mounting base 26 for fixing the boiler assembly is also arranged between the DC interface 241 and the AC interface 242. The mounting base 26 is used to install the boiler structure 2 inside the coffee machine body 1. The mounting base 26 can also be used to fix the water pipe 25, which increases the stability of the structure.

[0031] The coffee machine is provided with a power supply component 11 for supplying power to the boiler structure 2 at any position. The power supply component 11 includes an AC connection port 12 for supplying power to the AC heating tube 23 and a DC connection port 13 for supplying power to the DC heating tube 22. Either the AC connection port 12 or the DC connection port 13 can be used to supply power. The power supply component 11 is provided with two power supply components, which allows users to use it in different environments, increasing the convenience of use.

[0032] The coffee machine body 1 is provided with a water inlet 15 for water intake; the water inlet 15 can be used to connect water bottles or water pipes and other water supply devices, so that users can choose the water intake method and water storage container according to their needs and usage environment, which improves the convenience of users.

[0033] In this embodiment 1:

[0034] When the user selects to use AC connector 12 for power supply, the user can connect AC connector 12 to a location with AC power supply. Then, the current will supply power to the coffee machine body 1 through AC connector 12. At this time, the AC heating tube 23 installed in the coffee machine body 1 will be powered through AC interface 242. After the current flows through the AC heating tube 23, the AC heating tube 23 will heat up. Then, the water pipe 25 installed in the boiler structure 2 will heat up after being heated by the AC heating tube 23. After the water pipe 25 is heated, the boiler structure 2 will heat up to reach the temperature required for use. Example

[0035] When the user selects to use DC connector 13 for power supply, the user can remove the coffee machine body 1 from the base 14. At this time, the user can connect DC connector 13 to the battery pack for use. The battery pack is powered by the power cord, and then the current is supplied to the coffee machine body 1 through DC connector 13. At this time, the DC heating tube 22 installed in the coffee machine body 1 is powered through DC interface 241. After the current flows through the DC heating tube 22, the DC heating tube 22 will heat up. Then, the water pipe 25 installed in the boiler structure 2 will heat up after being heated by the DC heating tube 22. After the water pipe 25 is heated, the boiler structure 2 will heat up to reach the temperature required for use.

[0036] Multiple power supply options are available, allowing users to choose the appropriate power supply method based on different usage environments, thus increasing convenience during use.

[0037] In this utility model, a baffle 16 is provided outside the power supply component 11. By sliding the baffle 16, it is convenient for users to use different power supply components 11 and to block another power supply component 11.

[0038] Both the DC heating element 22 and the AC heating element 23 need to be preheated before they can be put into operation. This is because the AC heating element 23 receives a larger input voltage, so it heats up faster. The DC heating element 21 receives a smaller input voltage, so it heats up slower. During operation, only one heating element will be in operation at a time.

[0039] The power cord mentioned in this utility model is a conventional component to those skilled in the art, and therefore requires no further description or accompanying drawings.

[0040] The battery pack described in this utility model is an energy storage device, which is a well-known technical means and component in the art, and therefore does not require further description or accompanying drawings.
