When the air pump 20 is operated, as shown in fig. 5 and 7 (the arrows in the figures show the flowing direction of the fluid, and the arrows in the following figures are the same and not illustrated one by one), air in the brewing cup 13 can be sucked, so that negative pressure is formed in the brewing cup 13, and the liquid 17 in the container body 11 is sucked into the brewing cup 13, so that the material 18 is brewed. Subsequently, the air pump 20 is turned off to stop pumping, or air is blown into the brewing cup 13, as shown in fig. 6 and 8, the air pressure in the brewing cup 13 rises, the beverage made by the brewing material 18 in the liquid 17 can flow back to the container body 11 through the first filtering port 1311 and the water outlet 141, and the beverage is separated from the material 18, so that the material 18 is prevented from being soaked for a long time, and the taste of the beverage is improved. Meanwhile, the negative pressure pumping the liquid 17 can increase the disturbance to the liquid 17, thereby stirring the material 18 and contributing to the improvement of the brewing effect.

In addition, by arranging the first filtering port 1311 on the side wall of the brewing cup 13, on one hand, the material 18 can be intercepted in the brewing cup 13, the risk that the material 18 flows into the container body 11 is reduced, and the material 18 is enabled to realize centralized brewing in the brewing cup 13; on the other hand, compared with the case that the filter screen is additionally arranged in the brewing cup 13 for filtering, the filter screen can be omitted, so that the filter screen is prevented from floating or floating in the brewing cup 13 under the influence of the air pump 20, parts are reduced, and the cost is saved. Moreover, the brewing cup 13 is provided with the elastic stopper 14 capable of blocking the first filtering port 1311, the position of the elastic stopper 14 corresponding to the first filtering port 1311 is provided with the water outlet 141, and in the process that the air pump 20 blows air into the brewing cup 13, the water outlet 141 can be blown open, so that the liquid 17 in the brewing cup 13 can flow to the container body 11 through the first filtering port 1311 and the water outlet 141 to obtain brewed beverage, the water outlet 141 can realize secondary filtering, and the filtering effect is good. In a natural state or in the process of pumping the air in the brewing cup 13 by the air pump 20, the water outlet 141 can be closed under the action of the self elastic restoring force, or the water outlet keeps a closed state by matching with the pumping force of the air pump 20, so that the liquid 17 can be effectively prevented from leaking from the inside and the outside of the brewing cup 13 in the process of pumping and brewing, and the brewing effect is ensured. In addition, the water outlet 141 can be automatically opened and closed in the blowing and sucking processes of the air pump 20, and the air pump is simple in structure and accurate in control.

Optionally, as shown in fig. 1, the beverage brewing apparatus further comprises a container cover 12, the container cover 12 is arranged at the top opening of the container body 11, the cup body 131 of the brewing cup 13 is erected on the container cover 12, and the cup cover 133 is covered on the cup body 131 and is detachably connected with the container cover 12. Of course, the drink making apparatus may not have the container lid 12, and both the cup body 131 and the lid 133 of the making cup 13 are connected to the container body 11.

Optionally, as shown in fig. 1, a sealing ring 135 is sleeved on the cap 133, and the sealing ring 135 presses the inner side wall of the cup 131. The cup cover 133 is ensured to be sealed and covered on the cup body 131, so that air leakage is avoided during the operation of the air pump 20.

In some embodiments, as shown in fig. 3 and 4, the elastic stopper 14 is in the shape of a sleeve and is sleeved on the outer side wall of the brewing cup 13.

In these embodiments, the elastic stopper 14 is a sleeve-shaped post, which is sleeved on the brewing cup 13, so as to facilitate installation and to fully block the first filtering port 1311 in the circumferential direction. Moreover, the elastic stopper 14 is sleeved on the outer side wall of the brewing cup 13, in the blowing process of the air pump 20, the air can push the liquid 17 to flush the water outlet 141, and in the pumping process of the air pump 20, the elastic stopper 14 is limited by the side wall of the brewing cup 13 and can be tightly attached to the brewing cup 13, so that the closing state of the water outlet 141 is ensured, and the installation firmness of the elastic stopper 14 is ensured. In addition, the water outlet 141 is located at the outer side of the first filtering port 1311, so that the liquid 17 needs to flow through the water outlet 141 after being filtered by the first filtering port 1311, and the probability of clamping or blocking the material 18 with larger size at the water outlet 141 can be reduced.

In some embodiments, as shown in fig. 3 and 4, a detent 1312 is circumferentially disposed on an outer sidewall of the brewing cup 13, and the resilient stopper 14 is disposed within the detent 1312. The installation firmness of the elastic stopper 14 is improved, the elastic stopper 14 is prevented from falling off the brewing cup 13, the elastic stopper 14 is also prevented from moving up and down relative to the brewing cup 13, and the water outlet 141 and the first filtering port 1311 are correspondingly distributed.

In some embodiments, as shown in fig. 5 and 6, the first filter 1311 is elongated and the first filter 1311 extends upward from the bottom of the side wall of the brew cup 13.

In these embodiments, the first filtering opening 1311 is formed in an elongated shape, such as a narrow slit, which has a good filtering effect and can prevent a large amount of materials 18 such as tea leaves from leaking into the container body 11. Extending the first filter 1311 upwardly from the bottom of the side wall of the brewing cup 13, i.e., extending the first filter 1311 downwardly to the bottom of the side wall of the brewing cup 13, facilitates sufficient drainage of the liquid 17 in the brewing cup 13 and avoids long term deposition of the liquid 17 at the bottom of the brewing cup 13 that could affect drinking health.

In some embodiments, as shown in FIG. 3, the number of first filter ports 1311 is multiple, with multiple first filter ports 1311 being circumferentially spaced around the sidewall of brewing cup 13. Is beneficial to discharging the liquid 17 in multiple directions, avoids the liquid 17 from depositing in the brewing cup 13, is beneficial to quickly discharging the liquid 17 into the container body 11 and improves the brewing speed.

In some embodiments, the water outlet 141 is a slit. The processing is convenient, and the device can be closed tightly, thereby preventing the liquid 17 from leaking out in the brewing process of the brewing cup 13.

In some embodiments, as shown in fig. 3 and 4, the water outlet 141 is a through hole. The processing is convenient.

Further, the diameter of the through hole ranges from 0.05mm to 0.2 mm. If the size of the through hole is too large, the closing effect is affected, resulting in leakage of the liquid 17 during brewing of the brewing cup 13, and if the size of the through hole is too small, the speed of outflow of the liquid 17 is severely affected. Therefore, the diameter of the through hole is between 0.05mm and 0.2mm, and the through hole can be conveniently and tightly closed under the condition of meeting the water outlet requirement by using the tension of water.

In specific application, the diameter of the through hole can be about 0.1mm, and the through hole can be in various shapes such as a circular hole, a semicircular hole and the like.

In some embodiments, as shown in fig. 3 and 4, the number of the water outlets 141 is plural, and the plural water outlets 141 are spaced apart in a height direction of the first filtering port 1311. That is, one first filtering port 1311 corresponds to the plurality of water outlet ports 141. It is advantageous to have a small size of each outlet 141 in case of satisfying the discharge speed, thereby facilitating a tight closure.

In some embodiments, as shown in FIG. 9, the bottom wall of the brewing cup 13 is not provided with the second filter port 1313, but is closed. So that the liquid 17 flows out through the first filter 1311 and the outlet 141.

In other embodiments, as shown in FIGS. 10 and 11, a second filter 1313 is provided in the bottom wall of the brew cup 13. At this time, the liquid 17 in the brewing cup 13 can be discharged into the container body 11 through the first filtering port 1311 and the water outlet 141, or can be discharged into the container body 11 through the second filtering port 1313 at the same time, which is beneficial to meeting the requirement of quick brewing and meeting the requirement of short contact time between the liquid 17 and the material 18.

Further, the diameter of the second filtering port 1313 ranges from 0.1mm to 0.8 mm. If the second filter 1313 is too large, the liquid 17 in the brewing cup 13 will flow out through the second filter 1313 during the air pump 20 pumping the air in the brewing cup 13, which will affect the brewing effect. Moreover, if the size of the second filtering port 1313 is too large, the material 18 with small particles is liable to fall from the second filtering port 1313 into the container body 11, so that the finally prepared beverage is mixed with the material 18, which affects the drinking taste. If the size of the second filter 1313 is too small, the brewing speed will be affected. Therefore, the diameter of the second filtering port 1313 is 0.1mm to 0.8mm, and the water tension is used to facilitate the prevention of the liquid 17 in the brewing cup 13 from flowing out of the second filtering port 1313 during the suction of the air pump 20, and to facilitate the liquid 17 to flow into the container body 11 through the second filtering port 1313 during the blowing of the air pump 20, so as to accelerate the brewing speed and prevent the material 18 from leaking out through the second filtering port 1313.

Specifically, if the size of the second filtering port 1313 is made small during the process of sucking the gas in the brewing cup 13 by the gas pump 20, even though the brewing cup 13 and the container body 11 can communicate with each other through the second filtering port 1313, the communication effect is limited, and a negative pressure is still formed in the brewing cup 13 with respect to the container body 11, so that the liquid 17 in the container body 11 is sucked into the brewing cup 13 through the pipette 132. Furthermore, the liquid 17 in the brewing cup 13 is difficult to flow out through the second filter 1313 of smaller size by the tension and negative pressure effect of the water, thereby avoiding leakage of the liquid 17 in the brewing cup 13 during suction. While in the case that the air pump 20 blows air into the brewing cup 13, the liquid 17 in the brewing cup 13 can flow out of the second filtering port 1313 under the pushing action of the high-pressure air, so that the brewing speed is increased.

In a particular application, the size of the second filter 1313 can be referenced to the size of the material 18 to meet brewing and drainage requirements without affecting the leakage of the material 18.

In particular applications, the size of the second filter 1313 may also be designed with reference to the material of the brew cup 13. The second filter 1313 can satisfy the above requirements even under conditions of thermal expansion and contraction.
