DETAILED DESCRIPTION

[0017] In order to make the purposes, technical solutions and advantages of the present application clearer, the present application will be further described in detail below in combination with the drawings and embodiments. It should be understood that the specific embodiments described herein are only used to explain the present application and not used to limit the present application. Moreover, the embodiments in the present application and the features in the embodiments can be combined with each other without conflict.

[0018] Figure 1 A structural schematic diagram of a brewing device 100 of a coffee machine according to an embodiment of the present application is shown. Referring to Figure 1 As shown, the brewing device 100 of the coffee machine mainly comprises a brewing body 10, a first extraction cup 20 and a second extraction cup 30. The brewing body 10 is internally provided with a cup cover assembly 13, a linkage lifting assembly 12 driving the cup cover assembly 13 to vertically move up and down, and a water inlet assembly 14 mounted on the cup cover assembly 13 to move up and down together with the cup cover assembly 13. The specific implementation modes of the linkage lifting assembly 12, the cup cover assembly 13 and the water inlet assembly 14 are the prior art and are not the focus of the present application, so they will not be described in detail here. A mounting groove 11 is formed below the cup cover assembly 13 in the brewing body 10, for selectively mounting the first extraction cup 20 or the second extraction cup 30 in the transverse direction and can be removed reversely, referring to Figure 1As indicated by arrow 40, the first extraction cup 20 has a first extraction chamber 21 and a first handheld part 22. Similarly, the second extraction cup 30 has a second extraction chamber 31 and a second handheld part 32. The mounting groove 11 is open at the front and bottom in the direction of mounting the first extraction cup 20 or the second extraction cup 30. A left guide step 111 and a right guide step 112 are formed on the left and right sides of the mounting groove 11, respectively. The two sides of the first extraction cup 20 or the second extraction cup 30 can be slid into the mounting groove 11 along the left guide step 111 and the right guide step 112, respectively, so that the first extraction chamber 21 or the second extraction chamber 31 is directly opposite the cup cover assembly 13. Then, by rotating the operating lever 121 of the linkage lifting assembly 12, the cup cover assembly 13 can be moved down through the linkage lifting assembly 12 to seal the first extraction chamber 21 of the first extraction cup 20 or the second extraction chamber 31 of the second extraction cup 30 in the mounting groove 11. By rotating the operating lever 121 in the opposite direction, the cup lid assembly 13 can be moved upward through the linkage lifting assembly 12, and the first extraction cup 20 or the second extraction cup 30 can be pulled out in the opposite direction along the left guide step 111 and the right guide step 112.

[0019] See also Figure 1 Combination Figure 2 As shown, the first extraction cup 20 is in the lateral removable direction (i.e. Figure 1 A first magnetic element 23 is fitted onto the front side of the mounting slot 11 (in the direction indicated by the middle arrow 40), and a second magnetic element 24 is fitted onto the right side relative to the lateral removable direction. See also Figure 1 Combination Figure 3 As shown, the brewing body 10 has a magnetic attraction component 17 embedded on the outer rear side of the mounting groove 11. The position of the magnetic attraction component 17 corresponds to the position of the first magnetic component 23 after the first extraction cup 20 is inserted into the mounting groove 11. After the first extraction cup 20 is inserted into the mounting groove 11, the first magnetic component 23 and the magnetic attraction component 17 attract each other, thus installing the first extraction cup 20 into place. In addition, the brewing body 10 also has a first magnetic induction element 15 that cooperates with the first magnetic component 23 of the first extraction cup 20 and a second magnetic induction element 16 that cooperates with the second magnetic component 24 of the first extraction cup 20. See details. Figure 1 Combination Figure 3As shown, a mounting base 141 extends downward from the outer side of the brewing body 10, opposite the magnetic coupling component 17. The first magnetic induction element 15 is fixed to the mounting base 141 so that it moves up and down together with the water inlet assembly 14 and the cup lid assembly 13. The second magnetic induction element 16 is fixed to the outer right side of the brewing body 10 and is positioned directly opposite and close to the second magnetic component 24 after the first extraction cup 20 is inserted into the mounting groove 11. After the first extraction cup 20 is inserted into the mounting groove 11 and magnetically attracted into place, when the operating lever 121 is rotated to move the cup lid assembly 13 down to seal the first extraction chamber 21 of the first extraction cup 20, the first magnetic induction element 15 also moves down with the cup lid assembly 13 to a position directly opposite and close to the first magnetic component 23 and the magnetic coupling component 17 that are attracted to each other (see [reference]). Figure 3 As shown, the first magnetic element 23 triggers the second magnetic induction element 16 to generate a first electrical control signal, while the second magnetic induction element 16 is triggered by the second magnetic element 24 to generate a second electrical control signal. These first and second electrical control signals enable the coffee machine's electrical control system to control the water pump to inject hot water at a first pressure into the water inlet assembly 14. If the first extraction cup 20 is not properly installed or the cup lid assembly 13 is not lowered to a position sealing the first extraction chamber 21 of the first extraction cup 20, the first magnetic induction element 15 and the second magnetic induction element 16 cannot be triggered, and no electrical control signal will be generated to start the water pump to inject high-temperature, high-pressure hot water, thereby improving user safety.

[0020] See also Figure 1 Combination Figure 4 As shown, the second extraction cup 30 has a third magnetic element 33 embedded only on its front side facing the mounting groove 11 in the lateral removable direction, without any additional magnetic element on the right side corresponding to the first extraction cup 20. After the second extraction cup 30 is inserted into the mounting groove 11, the third magnetic element 33 and the magnetic attraction component 17 attract each other, thus installing the second extraction cup 30 into place. After the second extraction cup 30 is magnetically attracted into place in the mounting groove 11, when the operating lever 121 is rotated to lower the cup lid assembly 13 to seal the second extraction chamber 31 of the second extraction cup 30, the first magnetic induction element 15 also moves down with the cup lid assembly 13 to a position directly opposite and adjacent to the mutually attracted third magnetic element 33 and magnetic attraction component 17 (see [reference]). Figure 4 As shown in the diagram, the second magnetic induction element 16 is triggered by the third magnetic component 33 to generate a first electronic control signal. However, since there is an additional magnetic component on the right side of the second extraction cup 30, the second magnetic induction element 16 will not be triggered. The coffee machine's electronic control system only controls the water pump to inject hot water at the second pressure into the water inlet assembly 14 based on the first electronic control signal. If the second extraction cup 30 is not installed in place or the cup lid assembly 13 is not lowered to a position that seals with the second extraction chamber 31 of the second extraction cup 30, neither the first magnetic induction element 15 nor the second magnetic induction element 16 can be triggered, and no electronic control signal will be generated to start the water pump to inject high-temperature and high-pressure hot water, thereby improving the safety of user operation.

[0021] According to the above embodiments of the present application, since the first extraction cup 20 and the second extraction cup 30 are equipped into the installation groove 11 of the brewing body 10 to generate different electric control signals, i.e. the first electric control signal and the second electric control signal are generated when the first extraction cup 20 is equipped, and only the first electric control signal is generated when the second extraction cup 30 is equipped, the electric control system of the coffee machine can control the water pump to inject hot water with different pressures to the water inlet assembly 14 according to the different electric control signals, i.e. hot water with the first pressure is injected when the first extraction cup 20 is equipped, and hot water with the second pressure is injected when the second extraction cup 30 is equipped, so as to achieve the extraction requirement of different water injection pressures. In specific embodiments, the values of the first pressure and the second pressure can be set according to requirements, for example, the first pressure can be greater than the second pressure, so that high-pressure extraction can be performed using the first extraction cup 20, and low-pressure extraction can be performed using the second extraction cup 30. In order to facilitate use and identification, the first extraction cup 20 and the second extraction cup 30 can be set in different forms, for example, as shown in FIG. 6, the hand-held part 22 of the first extraction cup 20 can be a columnar handle, and the hand-held part 32 of the second extraction cup 30 can be a hand-held edge. Figure 1 As shown in FIG. 6, the hand-held part 22 of the first extraction cup 20 can be a columnar handle, and the hand-held part 32 of the second extraction cup 30 can be a hand-held edge.

[0022] According to specific embodiments of the present application, the first magnetic member 23 and the second magnetic member 24 on the first extraction cup 20 and the third magnetic member 33 on the second extraction cup 30 can be magnets, the magnetic attraction matching member 17 on the brewing body 10 can be a metal sheet attracted to the magnets, and the first magnetic induction element 15 and the second magnetic induction element 16 can adopt magnetic reed switch inductors. According to further specific embodiments of the present application, the distribution of the first position of the first magnetic member 23 on the first extraction cup 20 and the second position of the second magnetic member 24 on the first extraction cup 20 is not limited to the illustrated embodiments, as long as there is sufficient spacing between the first position and the second position to avoid false triggering of the first magnetic induction element 15 and the second magnetic induction element 16.

[0023] The above only describes the preferred embodiments of the present application and is not intended to limit the present application. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present application shall be included in the protection scope of the present application.
