The beverage brewing apparatus provided by the embodiment of the present invention will be described with reference to fig. 2 to 17.

As shown in fig. 2, 3 and 4, an embodiment of an aspect of the present invention provides a beverage brewing apparatus, which includes an air pump 19, a container body 11 for containing liquid, and a brewing cup 12 placed in the container body 11, wherein the brewing cup 12 includes a cup body 121 and a pipette 123 that are communicated, the cup body 121 can be communicated with the air pump 19, the pipette 123 is communicated with the container body 11, the beverage brewing apparatus further includes a strainer assembly 13 and a one-way valve 14, the strainer assembly 13 is disposed in the cup body 121, and the one-way valve 14 is disposed on the strainer assembly 13, so that the liquid in the pipette 123 can flow through the one-way valve 14 to the upper side of the strainer assembly 13.

According to the beverage brewing device provided by the embodiment of the utility model, the container body 11 is used for containing liquid, and the brewing cup 12 is used for containing materials to be brewed. The brewing cup 12 is in communication with the container body 11 and is capable of communicating with the air pump 19 of the drink brewing apparatus, thereby creating a sealed space within the brewing cup 12 in the event that the liquid level within the container body 11 forms a water seal over the bottom opening of the pipette 123. When the air pump 19 works, the arrows in the figure shown in fig. 5 show the flowing direction of the fluid, and the arrows in the following figures are the same and will not be described one by one, so that the air in the brewing cup 12 can be sucked, negative pressure can be formed in the brewing cup 12, and then the liquid in the container body 11 can be sucked into the cup body 121, and the brewing of the material can be realized. Subsequently, the air pump 19 is turned off to stop pumping, or the air is exhausted into the cup body 121, as shown in fig. 6, the air pressure in the brewing cup 12 rises, the beverage obtained by brewing the materials with the liquid can flow back to the container body 11, so that the beverage and the materials are separated, the materials are prevented from being soaked for a long time, and the taste of the beverage is improved. Meanwhile, negative pressure pumping liquid can increase disturbance to the liquid, so that stirring of materials is achieved, and the brewing effect is improved.

In addition, through set up filter screen subassembly 13 in cup 121, can be with the material interception in brewing cup 12, reduce the risk that the material flows in container body 11, guaranteed to realize concentrated the brewing in cup 121 to it is long to be convenient for reasonable control brewing. Moreover, the one-way valve 14 is arranged on the filter screen assembly 13, and in the air suction process of the air pump 19, as shown in fig. 5, 12 and 13, the one-way valve 14 is opened, so that the liquid can flow into the upper part of the filter screen assembly 13 through the one-way valve 14 to brew the materials, and the space in the one-way valve 14 is small, so that the liquid flowing into the one-way valve 14 has certain hydraulic pressure, the liquid can be rapidly flushed into the cup body 121, the materials can be conveniently rolled and brewed, and the brewing effect is improved. Furthermore, the one-way valve 14 does not allow the liquid to flow to the container 11 therethrough, so that during the pressure rising process in the cup body 121, as shown in fig. 6, 9, 11, 13 and 16, the one-way valve 14 is closed, the liquid has to flow to the container 11 through the filter screen assembly 13 around the one-way valve 14, compared with the scheme of circulating the liquid up and down by the filter screen assembly 13 without the one-way valve 14, the size of the opening for discharging the liquid downwards can be reduced, the speed for discharging the liquid outwards by the cup body 121 can be effectively reduced, the sufficient liquid can fully brew the materials, and the brewing effect can be improved.

Further, as shown in fig. 11 and 12, the brewing cup 12 includes a cup body 121 and a pipette 123 communicating with each other, and each communicating with the air pump 19 and the container body 11 to perform negative pressure pipetting. In the case of a constant height of the brewing cup 12, the volume of the brewing cup 12 can be greatly reduced by disposing the pipette 123 having a cross-sectional area much smaller than that of the cup body 121, so that a negative pressure can be rapidly formed after the air pump 19 is activated to suck the liquid in the container body 11 into the cup body 121 through the pipette 123. Meanwhile, the design of the pipette 123 can reserve more volume for the container body 11 to contain liquid, and can improve the brewing amount of drinks. At this time, the filter screen may be disposed in the cup body 121.

Alternatively, as shown in fig. 4 and 13, the pipette 123 is disposed at the center of the bottom wall of the cup body 121 and extends toward the bottom of the container body 11. The liquid is favorably fully stirred and infused after flowing into the cup body 121 through the liquid suction pipe 123.

Alternatively, as shown in fig. 4 and 13, the screen assembly 13 is disposed at the bottom of the cup 121. Enough space is reserved for the materials, and the liquid quantity of the brewing materials is increased.

Optionally, as shown in fig. 4 and 13, the brewing cup 12 comprises a cup body 121 and a cap 122 which are detachably and hermetically connected, the cap 122 can be opened to access the strainer assembly 13 and the material, and the cup body 121 can be cleaned for use. Specifically, the cap 122 is sleeved with a sealing ring 125, which is in sealing engagement with the cup 121.

Alternatively, as shown in fig. 4 and 13, a vent is provided in the cap 122 so that the cup 121 communicates with the air pump 19 through the vent. Furthermore, a cup cover filter screen 124 is arranged at the vent to prevent the material from floating up to enter the vent and enter the air pipe 16 communicated with the air pump 19 to influence the suction effect of the air pump 19.

Alternatively, as shown in fig. 4 and 13, the container body 11 includes a body 111 and a container cover 112, wherein the body 111 is formed with an opening at the top thereof and a water outlet is formed at the side of the top thereof, and the container cover 112 is closed on the top of the body 111 to separate the opening of the body 111 from the water outlet. The brewing cup 12 is configured to fit within the container lid 112 and to overlap a step formed by the container lid 112, and the lid 122 of the brewing cup 12 fits within the container lid 112 to seal the cup body 121.

With respect to the location of the one-way valve 14, in some embodiments, the one-way valve 14 is located on the screen assembly 13 corresponding to the location of the pipette 123, as shown in fig. 11, 12, and 13.

In these embodiments, the positions of the check valve 14 and the liquid suction pipe 123 are distributed up and down relatively, and when the air pump 19 sucks air and negative pressure is formed in the cup body 121, because the force of upward impact of the liquid flowing out through the liquid suction pipe 123 is large, the check valve 14 is favorable for floating upward under the action of the negative pressure or further matched with the impact force of the liquid to overcome the self gravity, so that the check valve 14 is favorable for being fully opened. Moreover, the liquid can directly flow upwards to the one-way valve 14 quickly after flowing out of the liquid suction pipe 123, and quickly flush the brewing material above the filter screen assembly 13, so that the material can be rolled and brewed conveniently, and the brewing effect is improved.

Of course, in other embodiments, the check valve 14 may be spaced apart from the pipette 123 in the horizontal direction. I.e. the one-way valve 14 is not located directly above the pipette 123. At this time, after the liquid flows into the cup body 121 through the liquid suction pipe 123, the liquid first flows in a substantially lateral direction, fills the space between the bottom wall of the cup body 121 and the strainer assembly 13, and then flows upward through the check valve 14 and the strainer assembly 13 to brew the material.

The number of the check valves 14 may be one or plural. In the case where the number of the check valves 14 is plural, one check valve 14 may be located directly above the pipette pipe 123, or all the check valves 14 may be located away from the pipette pipe 123 and not located directly above the pipette pipe 123.

Regarding the manner of opening and closing the check valve 14, in some embodiments, the check valve 14 is made openable by the suction of the air pump 19, and the check valve 14 is also made closable by the discharge of the air pump 19.

In these embodiments, the check valve 14 is not directly opened or closed by electric control, but is automatically opened or closed under the pressure in the cup body 121, and the check valve 14 with a simple structure can be configured, so that the cost is saved, and the probability of false opening is reduced. Specifically, the check valve 14 can be opened by the air pump 19, and at this time, the check valve 14 can be opened only by the negative pressure in the cup body 121, or by the impact of the liquid flowing into the cup body 121 according to the negative pressure, so as to ensure that the liquid can flow through the check valve 14 to brew the material. Furthermore, the one-way valve 14 can be closed under the exhaust action of the air pump 19, at this time, the pressure in the cup body 121 rises, and the one-way valve 14 is closed under the action of the self gravity, so that the liquid cannot flow to the container body 11 through the one-way valve 14.

Regarding the structure of the check valve 14, in some embodiments, as shown in fig. 7 to 10, the check valve 14 includes a valve body 141 connected to the screen assembly 13 and a valve ball 142 disposed in the valve body 141, a liquid inlet passage 1411 is disposed in the valve body 141, the valve ball 142 can float up to open the liquid inlet passage 1411 by the suction of the air pump 19, and the valve ball 142 can also fall back to seal the liquid inlet passage 1411 by the exhaust of the air pump 19. The structure is simple. It should be noted that, when the liquid inlet channel 1411 is opened by the valve ball 142, the liquid inlet channel 1411 is entirely communicated, and a part of the liquid inlet channel 1411 sealed by the valve ball 142 is blocked by the valve ball 142. Specifically, as shown in fig. 10, under the suction action of the air pump 19, the ball 142 of the check valve 14 may float up to open the liquid inlet passage 1411. As shown in fig. 9, under the exhaust action of the air pump 19, the valve ball 142 of the check valve 14 falls back by its own weight, sealing the liquid inlet passage 1411.

Further, as shown in fig. 7 to 10, the check valve 14 further includes a valve net 143 disposed at an outlet of the liquid inlet passage 1411, the valve net 143 is located above the valve ball 142, and the valve net 143 has a valve net 143 hole for liquid to flow through. On one hand, the liquid can flow into the cup body 121 to brew materials through the holes 143 of the valve mesh; on the other hand, the material is blocked by the valve net 143, the material is prevented from entering the valve body 141 to block the liquid inlet passage 1411, and the material is prevented from entering the container body 11 through the one-way valve 14 and the brewing pipe.

For installation of the valve net 143, as shown in fig. 9 and 10, an annular groove 1412 may be provided on a side wall of the liquid inlet passage 1411, and the valve net 143 may be clamped in the annular groove 1412. The mounting structure is simple, the mounting firmness of the filter screen is good, and the filter screen is prevented from being separated from the valve body 141 under the action of negative pressure and liquid impact.
