A beverage brewing apparatus provided by an embodiment of the present invention will be described with reference to fig. 1 to 18.

As shown in fig. 1 to 3 and 8, an embodiment of an aspect of the present invention provides a beverage brewing apparatus, including: the container body 10, the bottom of the container body 10 has ventilating upper connectors 15, the middle part of the ventilating upper connector 15 has first ventilating pipes 151; the base 20 is used for bearing the container body 10, a lower ventilating connector 21 coupled with the upper ventilating connector 15 is arranged on the base 20, and a second ventilating pipeline 22 is arranged in the middle of the lower ventilating connector 21; and a dust cover provided at the top opening of the second air passage 22, the dust cover being openable in a state where the container body 10 is placed on the base 20 so that the first air passage 151 is inserted into the second air passage 22 through the dust cover, the dust cover being closable in a state where the container body 10 is detached from the base 20.

In the beverage brewing device provided by the embodiment of the aspect, the upper ventilating connector 15 is arranged at the bottom of the container body 10, and the lower ventilating connector 21 is arranged on the base 20, so that power can be conveniently supplied to elements in the container body 10. In addition, as shown in fig. 1, a first vent pipe 151 is arranged in the middle of the upper vent connector 15, and a second vent pipe 22 is arranged in the innermost coupling ring of the lower vent connector 21, so that the first vent pipe 151 and the second vent pipe 22 can be connected in a plugging manner along with the plugging and pulling connection of the upper vent connector 15 and the lower vent connector 21, and the air pump 23 is favorably communicated with the brewing cup 14 through the first vent pipe 151 and the second vent pipe 22, so that the space utilization rate is improved on one hand, an installation space is not required to be additionally provided for the first vent pipe 151 and the second vent pipe 22, on the other hand, the vent pipes are favorably limited through the connectors, and the accuracy of the plugging and the communication of the first vent pipe 151 and the second vent pipe 22 is improved. Moreover, after the upper ventilation connector 15 and the lower ventilation connector 21 are coupled, the joint of the first ventilation pipeline 151 and the second ventilation pipeline 22 can be effectively shielded, so that the phenomenon that external water or impurities enter the ventilation pipeline to cause blockage and influence the suction effect is avoided.

In addition, a dust cover is arranged at the top opening of the second air passage 22, and the first air passage 151 needs to penetrate through the dust cover and be inserted into the second air passage 22, so that the dust cover can seal a gap between the first air passage 151 and the second air passage 22, and external dust is prevented from entering a pipeline through which the first air passage 151 and the second air passage 22 are communicated with each other. After the second air duct 22 is pulled out of the first air duct 151, the dust cover is closed, so that impurities such as external dust can be shielded, and the situation that the top opening of the second air duct 22 is exposed and deposits impurities to cause blockage after the container body 10 leaves the base 20 is avoided; on the other hand, the effusion in the second air passage 22 can be prevented from flowing out through the top opening, especially under the condition that the base 20 is inclined, the effusion can be prevented from flowing out and contacting with the electrode 212 on the ventilation lower connector 21 or the contact on the ventilation upper connector 15, the electric shock risk is reduced, and the use safety of the product is ensured.

In the case where the container body 10 is removed from the base 20 and the top surface of the base 20 is completely exposed, if the base 20 is tilted, the liquid in the upper channel of the base 20 can easily flow out through the top opening of the second vent channel 22 and over the coupling ring of the vent lower connector 21 to contact the electrodes 212 or contacts, causing contact risk, short circuit, or burning out of the product. And this embodiment sets up the dust cover through the top opening at second vent pipe 22, takes off the back from base 20 at container body 10, makes the dust cover closed, can effectively block hydrops outflow second vent pipe 22 to reduce the risk of electrocution.

In these embodiments, the container body 10 is used to contain the liquid 50 and the brewing cup 14 is used to contain the material 60 to be brewed. As shown in fig. 1, the air pump 23 is arranged in the base 20, so that on one hand, the gravity center of the beverage brewing device can be moved down as much as possible, the stability of the overall structure of the beverage brewing device is ensured, and the risk of toppling is reduced; on the other hand, it helps to reduce the volume of the container body 10 and make the container body 10 beautiful. Further, the air pump 23 is allowed to communicate with the brewing cup 14 through the second vent line 22 and the first vent line 151, so that a sealed space is established in the brewing cup 14 in the case where the liquid level in the container body 10 forms a water seal over the bottom opening of the liquid suction pipe 143. When the air pump 23 is operated, air in the brewing cup 14 can be sucked through the second air duct 22 and the first air duct 151, so that negative pressure is formed in the brewing cup 14, and the liquid 50 in the container body 10 is sucked into the brewing cup 14 through the liquid suction pipe 143, so as to brew the material 60 (referring to fig. 2, a state that the liquid 50 enters the brewing cup 14 under the action of the negative pressure to brew the material 60 is shown). Subsequently, the air pump 23 is turned off to stop pumping or blowing air into the brewing cup 14, as shown in fig. 3 (the arrow in the figure shows the flow direction of the fluid), so that the air pressure in the brewing cup 14 rises, the beverage obtained by brewing the material 60 with the liquid 50 can flow back to the container body 10, and the beverage is separated from the material 60, so that the material 60 is prevented from being soaked for a long time, and the taste of the beverage is improved.
