The first blocking member 23 includes an insertion rod 231 inserted into the first air extraction hole 22, and a sealing cover 232 connected to the outer end of the insertion rod 231. The sealing cover 232 is configured to be a flexible material covering the first air extraction hole 22, and at least the peripheral edge thereof can be folded toward a side away from the storage container 2 to open the first air extraction hole 22. Preferably, the above-mentioned flexible material is silicone.

[0034] See also Figure 7 The sealing cover 232 is configured as an arc-shaped structure that bends from the middle toward the storage container 2. The arc-shaped structure can make it easier to deform when folded.

[0035] See also Figure 7 The insert rod 231 is further provided with a stopper 233 abutting against the first air extraction hole 22 at one end opposite to the sealing cover 232 , and the stopper 233 is used to prevent the first blocking member 23 from escaping from the first air extraction hole 22 .

[0036] See also Figure 7 The exhaust joint 5 is provided with a first exhaust channel 51 connected with the first exhaust hole 22. The first exhaust channel 51 is provided with a partition 52. The partition 52 is provided with a second exhaust hole 53. The second exhaust hole 53 is provided with a second blocking member 54. The second blocking member 54 can float relative to the partition 52 along the extension direction of the first exhaust channel 51 to open or close the second exhaust hole 53.

[0037] See also Figure 6 and Figure 7 The second blocking member 54 includes a shaft portion 541 passing through the second air pumping hole 53, a plug 542 connected to one end of the shaft portion 541 close to the first air pumping hole 22 for sealing the second air pumping hole 53, and a trigger portion 543 connected to the other end of the shaft portion 541. Specifically, an elastic reset member 56 is provided between the trigger portion 543 and the partition 52. The elastic reset member 56 can realize the floating of the above-mentioned second blocking member 54. The arrangement of the above-mentioned second blocking member 54 forms a one-way valve structure. The second blocking member 54 will open the second air pumping hole 53 to realize the flow of gas only when it moves in the direction of the first air pumping hole 22, thereby ensuring the airtightness of the accommodating chamber 21.

[0038] See also Fig. 9 The trigger portion 543 is located on an end surface away from the second air suction hole 53 and has a plurality of air flow grooves 55 .

[0039] See also Figure 7The end of the shaft portion 541 connected to the plug 542 is contracted inward relative to the end connected to the trigger portion 543 . This arrangement can increase the flow rate of gas flowing through the second air suction port 31 .

[0040] See also Figures 6 to 8 , and also includes a sealing cap 544 which is sleeved on the shaft portion 541 and located between the plug 542 and the partition plate 52 , and the sealing cap 544 is circumferentially provided with a sealing flange 545 for abutting against the outer periphery of the second air exhaust hole 53 .

[0041] See also Figure 6 The exhaust connector 5 is detachably connected to the storage container 2 . This arrangement facilitates maintenance of the first blocking member 23 .

[0042] See also Figure 7 When the air extraction connector 5 is inserted into the vacuum port 4, the outer wall of the air extraction connector 5 abuts against the inner wall of the side enclosure 43, the sealing sleeve 412 is placed in the first air extraction channel 51, and the ribs 413 abut against the inner wall of the first air extraction channel 51. The ribs 413 can further enhance the sealing performance of the sealing sleeve 412 and the first air extraction channel 51 when they cooperate to prevent air leakage. The ejector pin 41 is provided with one end of the pushing top portion 411 pushing the second blocking member 54 toward the side close to the second air extraction hole 53, thereby opening the second air extraction hole 53 and connecting with the first air extraction channel 51 through the air flow groove 55, and starting The negative pressure generated by the vacuum device 3 can cause the sealing cover 232 to fold toward the side close to the second blocking member 54 to open the first air suction hole 22, thereby evacuating the accommodating cavity 21 of the storage container 2 through the first air suction channel 51, the air flow groove 55, the second air suction channel 42, the second air suction hole 53, and the first air suction hole 22. The above-mentioned conical surface 414 and guide surface 415 can make the gas flow toward the first air suction channel 51. When the gas encounters the conical surface 414 and the guide surface 415, it will flow toward the air flow groove 55 along the guide surface 415 and the conical surface 414, thereby playing a guiding role for the gas.

[0043] like Figure 8 As shown, after the vacuum connector 5 is separated from the vacuum port, the second blocking member 54 moves toward the direction close to the ejector pin 41 under the action of the elastic reset member 56, so that its plug 542 seals the second vacuum hole 53 again, and the sealing cover 232 of the first blocking member 23 will be folded and restored toward the direction of the first vacuum hole 22 due to the pressure difference between the atmospheric pressure and the air pressure in the accommodating chamber 21, and will be pressed against the first vacuum hole 22 by the atmospheric pressure, thereby sealing the first vacuum hole 22 again. The above-mentioned arrangement utilizes a double blocking member to seal the accommodating chamber 21, and has good airtightness, so the vacuuming effect is good, and the coffee beans or coffee powder can be effectively preserved to ensure its quality, and ensure that the brewed coffee has a better taste.

[0044] The conical structure with a narrow front end and a wide rear end formed by the above-mentioned ribs 413 enables the front end to produce a large deformation when squeezed and adapt to the inner surface of the first air exhaust channel 51, thereby fitting tightly on the inner surface of the first air exhaust channel 51 to improve the airtightness. Arranging multiple ribs can further improve the sealing effect, thereby preventing air leakage.

[0045] Therefore, compared with the prior art, the coffee machine provided by the utility model can not only provide a high-quality coffee experience when making coffee, but also transfer the coffee beans or coffee powder to the storage container 2 when they are not completely consumed, and evacuate the storage container 2 through the built-in vacuum device 3, so as to vacuum-seal and preserve the remaining materials, effectively isolate air and moisture, prevent the coffee beans and coffee powder from deteriorating, and ensure that the coffee made each time can maintain the best taste and quality.

[0046] According to the disclosure and teaching of the above description, the technical personnel in the field to which the utility model belongs can also change and modify the above implementation. Therefore, the utility model is not limited to the specific implementation methods disclosed and described above, and some modifications and changes to the utility model should also fall within the scope of protection of the claims of the utility model. In addition, although some specific terms are used in this specification, these terms are only for the convenience of description and do not constitute any limitation to the utility model.
