[0022] As shown in Figure 3 and Figure 4 The lifting member comprises a fixed ring 91, which is fixedly connected to the inner wall of the placing groove of the mounting head 3; a sliding rod 9, which is slidably mounted on the fixed ring 91, the top surface of the sliding rod 9 is an inclined surface and is in contact with the outer wall of the powder box 6; a spring 10, which is arranged between the fixed ring 91 and the sliding rod 9, and acts on the sliding rod 9 to make the sliding rod 9 able to lift the powder box 6 upward; an inclined plate 11, which is fixedly connected to the lower rod body of the sliding rod 9; a push block 12, which is mounted on one end of the sliding frame 8 in the placing groove of the mounting head 3, the inclined surface of the push block 12 is in sliding contact with the inclined plate 11, the push block 12 on the sliding frame 8 is pressed on the inclined plate 11 by the operating block 81, so that the sliding rod 9 can be limited on the bottom surface of the placing groove of the mounting head 3 by the push block 12, and when the push block 12 on the sliding frame 8 no longer presses the inclined plate 11, the sliding rod 9 can be lifted on one side of the powder box 6 upward under the action of the spring 83, facilitating the user to take down the powder box 6 from the mounting head 3.

[0023] As shown in Figure 3 and Figure 5As shown, the coffee outlet at the bottom of the mounting head 3 is provided with a threaded opening, and the dosing head 7 is screwed into the coffee outlet at the bottom of the mounting head 3 through the threaded opening. The dosing head 7 is in the shape of a bridge and is provided with two flow guide grooves. The dosing head 7 is assembled to the coffee outlet at the bottom of the mounting head 3, so that the coffee ejected from the coffee machine body 1 can be divided and discharged, and the dosing head 7 and the coffee outlet of the mounting head 3 can be conveniently cleaned and maintained. A spring 83 is arranged between the operating block 81 and the handle 5. The spring force of the spring 83 is greater than that of the spring 10. Under the action of the spring 10, the operating block 81 can pull the sliding frame 8, so that the push block 12 on the sliding frame 8 is always pressed against the inclined plate 11 of the sliding rod 9. When the user installs the mounting head 3 to the mounting ring 2, the operating block 81 can be pulled manually to save labor.

[0024] As shown in Figure 4 and Figure 5 The first magnetic block 13 and the second magnetic block 14 are further included. The interior of the operating block 81 is provided with a slot, and the first magnetic block 13 is fixedly installed in the slot. The second magnetic block 14 is fixedly installed on the outer wall of the powder box 6. The first magnetic block 13 and the second magnetic block 14 are opposite magnetic bodies. When the powder box 6 is placed on the support ring 31, the second magnetic block 14 penetrates into the sliding rod 9 and is attracted by the first magnetic block 13. When the handle 5 and the mounting head 3 are inverted, the powder box 6 cannot fall out of the mounting head 3, and the cleaning efficiency of the filtered coffee residues in the powder box 6 is improved.

[0025] Firstly, the user needs to put the powder box 6 into the placing groove of the mounting head 3, and due to the design of the sealing ring between the bottom of the powder box 6 and the blocking ring 31, it is ensured that the powder box 6 is placed stably and also ensures good sealing effect, preventing coffee liquid from leaking during brewing. The powder box 6 contains coffee powder to be brewed, and then the user installs the mounting head 3 to the material outlet of the coffee machine body 1 through the handle 5, and rotates the mounting head 3 to make the clamping ball 4 at the top of the mounting head 3 rotate and clamp into the clamping groove 21 at the bottom of the mounting ring 2. When the mounting head 3 is correctly installed, the coffee machine starts to work, and hot water is added to the coffee powder in the powder box 6 through the material outlet, and the coffee liquid flows into the placing groove of the mounting head 3 through the bottom of the powder box 6, and then flows out from the coffee liquid outlet at the bottom of the mounting head 3. In order to ensure that the coffee liquid flows out smoothly and facilitates subsequent cleaning, a threaded spout is arranged at the coffee liquid outlet, which allows the user to install or remove the discharging head 7 as needed. When the discharging head 7 is installed, the coffee liquid will flow out from the two side flow grooves of the discharging head 7. After the coffee brewing is completed, the user can easily take out the powder box 6 by pushing the operating block 81. When the user pushes the operating block 81, the operating block 81 moves against the resistance of the spring one 83, drives the push block 12 on the sliding frame 8 to no longer press the inclined plate 11 of the sliding rod 9. At this time, the sliding rod 9 moves upward under the action of the spring two 10, and the inclined surface thereof contacts with the outer wall of the powder box 6 and gradually lifts one side of the powder box 6, so that the powder box 6 is easily taken out by the user. In addition, in order to prevent the powder box 6 from accidentally falling off in the inverted state, the second magnetic block 14 is fixed outside the powder box 6, and the first magnetic block 13 inside the operating block 81 is attracted to each other, so that the powder box 6 can be kept stable even in the inverted state.

[0026] It should be understood that the above description is only for exemplary purposes and does not mean to limit the present application. Those skilled in the art will understand that the variations of the present application will be included in the scope of the claims herein.
