[0019] (III) Beneficial effects

[0020] The present invention provides a press-type coffee machine, which has the following beneficial effects:

[0021] (1) The press-type coffee machine uses an egg bin to squeeze the air egg to move the valve body, and the top tip breaks the seal of the air egg, allowing gas to enter the valve body, and the internal air pressure of the valve body increases. When the air pressure is greater than the elastic force of the second spring, it compresses the valve stem with the second sealing member to move toward the direction of the container body, opening the one-way valve, and gas enters the interior of the container body. After inflation is completed, the accessory valve stem is reset and the airway is sealed. The second spring, valve stem and second sealing member in the third component can seal the airway between the third component and the connecting cover, so that it is in a sealed state under normal conditions. Then the air egg and the egg bin are removed from the fourth component, the pressing member is installed on the second component, and the fixing member is rotated on the second component. Due to the sealing of the connecting cover by the axis and the fourth sealing member, the coffee machine is in a sealed state. In addition, the liquid outlet member and the sleeve rod are in a pluggable design. When storing the coffee machine, the liquid outlet member can be unplugged, which is convenient for users to store it and saves storage space.

[0022] (2) When the press-type coffee machine needs to be used to discharge liquid, the liquid discharge part is inserted, and force is applied to the press part to force the press part to move downward, thereby opening the lower sealing port of the connecting cover. Then, the liquid inside the container body enters the interior of the connecting cover through the guide rod, and enters the sleeve rod and the liquid discharge part, and flows out of the container through the liquid outlet. The sliding guide surface of the hole on the connecting cover is sealed by the third spring, the second pressure plate, the third seal and the axis. Due to the upward action of the third spring, the axis and the fourth seal normally seal the inner lower liquid outlet hole of the connecting cover. The guide rod guides the liquid in the container through the silicone tube, so that the liquid can only flow out from the liquid outlet. Then, the press part is released, and the axis is pushed upward under the action of the third spring. The axis with the fourth seal seals the connecting cover again, and the conventional faucet is changed into a plug-in tube, which saves money. When in use, there are only two actions, namely pressing and releasing, which is more convenient to use. BRIEF DESCRIPTION OF THE DRAWINGS

[0041] like Figure 7 and Figure 8 As shown, a pull ring 6 is hung on the outer surface of the top end of the valve core 1, and the pull ring 6 is convenient for users to operate.

[0042] like Figure 5 As shown, the upper outer surface of the container body 38 may also be threadedly connected to a first connecting body 36, and the first connecting body 36 includes a fourth component 35, a liquid outlet 26 and a second component 20. The positional relationship between these three is the same as that of the second connecting body 37. Replacing the second connecting body 37 with the first connecting body 36 can facilitate the placement of the coffee machine when not in use.

[0043] like Figure 4 , Figure 5 and Figure 6 As shown, a pressing piece 21 is sleeved on the outer surface of the upper end of the second component 20, and the middle position of the pressing piece 21 is sleeved on the outer surface of the upper end of the pressure cover 27. The outer surface of the valve body 12 is threadedly connected to the fixing piece 18 at one end away from the connecting cover 33. The pressing piece 21 is located between the fixing piece 18 and the valve body 12.

[0044] like Figure 4 and Figure 5 As shown, the second component 20 and the fourth component 35 are located on the same horizontal line, the shape of the pressing member 21 allows it to be simultaneously mounted on the second component 20 and the fourth component 35, and the fixing member 18 can fix the pressing member 21 on the second component 20 to ensure that the coffee machine can discharge liquid through the pressing member 21.

[0045] like Figure 1 and Figure 5 As shown, a silicone tube is disposed inside the container body 38, and the silicone tube is sleeved on the outer surface of the guide rod 34 near the bottom end to ensure the normal operation of the coffee machine.

[0046] Working principle: When using the press-type coffee machine, the egg bin 17 is first used to squeeze the gas egg 16 to move the valve body 12, and the top 13 breaks the seal of the gas egg 16, and the gas enters the valve body 12. The internal air pressure of the valve body 12 increases. When the air pressure is greater than the elastic force of the second spring 9, it presses the valve stem 10 with the second sealing member 11 to move toward the container body 38, opening the one-way valve, and the gas enters the interior of the container body 38. After the inflation is completed, the accessory valve stem 10 is reset, the airway is sealed, and the second spring 9, the valve stem 10 and the second sealing member in the third component 19 are in contact with each other. The sealing member 11 can seal the air passage between the third component 19 and the connecting cover 33, so that the air passage is in a sealed state under normal conditions. Then, the air egg 16 and the egg chamber 17 are removed from the fourth component 35, and the pressing member 21 is installed on the second component 20. The fixing member 18 is rotated on the second component 20. Due to the sealing of the connecting cover 33 by the shaft 31 and the fourth sealing member 32, the coffee machine is in a sealed state. The liquid outlet member 26 and the sleeve rod 22 are in a pluggable design. When the coffee machine is stored, the liquid outlet member 26 can be unplugged for easy storage. The user can store it to save storage space. When the coffee machine needs to be used to discharge liquid, the liquid discharge member 26 is inserted, and force is applied to the pressing member 21 to force the pressing member 21 to move downward, thereby opening the lower sealing opening of the connecting cover 33. Then, the liquid inside the container body 38 enters the inside of the connecting cover 33 through the guide rod 34, and enters the sleeve rod 22 and the liquid discharge member 26, and flows out of the container through the liquid outlet 25. The sliding guide surface of the hole on the connecting cover 33 is sealed by the third spring 28, the second pressing plate 29, the third sealing member 30 and the shaft 31. Due to the upward action of the third spring 28, the shaft 31 and the fourth sealing member 32 normally seal the inner lower liquid outlet of the connecting cover 33, and the guide rod 34 guides the liquid in the container through the silicone tube, so that the liquid can only flow out from the liquid outlet 25. Then the pressing piece 21 is released, and the shaft 31 is pushed upward under the action of the third spring 28. The shaft 31 with the fourth sealing member 32 seals the connecting cover 33 again, and the conventional faucet is changed into a plug-in tube, which saves money. There are only two actions, pressing and releasing, when using it, which is more convenient to use.
