The embodiment of the utility model provides a container 10, wherein a container body 11 is used for containing liquid, and a 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 30 of the drink brewing apparatus such that a sealed space is created within the brewing cup 12 without the liquid level within the container body 11 forming a water seal across the bottom opening of the brewing cup 12. When the air pump 30 is operated, as shown in fig. 3 and 4 (the arrows in the figures 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), air in the brewing cup 12 can be sucked, so that negative pressure is formed in the brewing cup 12, and the liquid in the container body 11 is sucked into the brewing cup 12, so that the brewing of the material is realized. Subsequently, the air pump 30 is turned off, as shown in fig. 5, the pumping can be stopped, the air pressure in the brewing cup 12 is increased, the beverage obtained by brewing the material with the liquid can flow back to the container body 11, and the separation of the beverage and the material is realized, so that the long-time soaking of the material is avoided, 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, when the beverage is brewed, especially when cold soaking is realized by low-temperature liquid, the material is easy to float on the liquid surface, and the brewing effect is influenced. By providing the sieve assembly 13, in particular two sieves of different heights, in the brewing cup 12, for example with the first sieve 131 on top and the second sieve 132 on bottom, a space for the movement of the material can be enclosed in the brewing cup 12, so that the material is confined in this space. On one hand, the liquid level can be at least increased to the first filter screen 131 during brewing, the first filter screen 131 can be used for blocking materials to prevent the materials from floating upwards, the materials are completely soaked in the liquid during brewing, and the brewing effect is favorably improved. On the other hand, the second filter screen 132 can intercept the materials in the brewing cup 12, reduce the risk of the materials flowing into the container body 11, ensure that centralized brewing is realized in the brewing cup 12, and is convenient for reasonably controlling the brewing time, which is also beneficial to improving the brewing effect, and can realize the separation of the materials and the beverage, so that the beverage is easy to drink.

Alternatively, as shown in fig. 5, the container body 11 includes a body 111 and a container cover 112, wherein the top of the body 111 is formed with an opening and a water outlet is formed at the side of the top, and the container cover 112 is closed on the top of the body 111 to separate the top 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.

In some embodiments, as shown in FIG. 5, brewing cup 12 includes cup 121 and lid 122 releasably sealingly connected, and first screen 131 is connected to lid 122.

In the embodiments, by arranging the cup 121 and the cap 122, the cap 122 can be opened to take and put materials, and the cup 121 can be cleaned, so that the convenience of use and maintenance of products can be improved. By connecting the first filter screen 131 with the cup cover 122, on one hand, the setting height of the first filter screen 131 can be raised, so that the moving space of the material is enlarged, and the material is fully contacted with the liquid in the brewing cup 12; on the other hand, the flow obstruction of the liquid in the brewing cup 12 can be reduced, the disturbance intensity of the liquid when the liquid is sucked under negative pressure is ensured, and the brewing effect is improved.

In some embodiments, as shown in fig. 5, the screen assembly 13 further includes a connector 133 coupled to the cap 122, and the first screen 131 is removably coupled to the connector 133.

In these embodiments, through set up on the bowl cover 122 can dismantle the connecting piece 133 of being connected with first filter screen 131, can realize dismantling of first filter screen 131 and bowl cover 122 and be connected, be convenient for pull down first filter screen 131 clean or maintain the change, can clean the part that bowl cover 122 is covered by first filter screen 131 simultaneously, reducible product health dead angle promotes clean convenience, both can ensure food hygiene safety, helps prolonging the life of product again.

In some embodiments, the connector 133 is configured as a fluid level probe.

In these embodiments, by configuring the connector 133 specifically as a level probe, it is possible to detect whether the liquid level within the brewing cup 12 reaches at least the set height of the first sieve 131. Specifically, a grounded conductor may be provided on the inner bottom wall of the container body 11 (for example, when the inner bottom wall of the container body 11 is provided with the liquid heating device 40, the liquid heating device 40 may be grounded), and the liquid between the conductor and the connecting member 133 may be used as a conductor, so that when the liquid in the container body 11 enters the brewing cup 12 under the negative pressure suction effect and rises to contact with the connecting member 133, the conductor can be conducted to the connecting member 133, and the liquid level can be detected by the conducted electric signal. In addition, as shown in fig. 6, a lead 1331 may be provided for the connector 133 to transmit a liquid level detection signal to the controller 50 of the beverage brewing apparatus (i.e., the connector 133 is electrically connected to the controller 50), and a wireless transmitter may be provided for the connector 133 to transmit a wireless liquid level detection signal to the controller 50 (i.e., the connector 133 is in signal connection with the controller 50), thereby controlling the air pump 30 to operate to pump liquid. On the one hand, the liquid level in the brewing cup 12 can be ensured to reach at least the height, so that the material can be completely soaked in the liquid under the blocking of the first filter screen 131, and the brewing effect is ensured; on the other hand, can in time close air pump 30 according to the liquid level testing result, help reducing the liquid level too high and lead to liquid to get into the air flue and damage the risk of air pump 30. Alternatively, as shown in fig. 6, the air pump 30 includes an intake pump 31 and an exhaust pump 32. The air suction pump 31 can realize negative pressure brewing, the exhaust pump 32 can exhaust air into the brewing cup 12 after the air suction pump 31 is closed, the air pressure in the brewing cup 12 is rapidly increased, and the liquid in the brewing cup 12 is discharged to the container body 11, so that the brewing time is conveniently and accurately controlled, and the liquid can be discharged by positive pressure to realize stirring of materials. At this time, if it is determined that the liquid level reaches the set height of the first filter screen 131, the suction pump 31 may be turned off, and if it is determined that the liquid level is too high, the exhaust pump 32 may be operated for a short time to rapidly reduce the liquid level, which not only sufficiently reduces the risk that the air pump 30 is damaged by the liquid entering the air passage, but also avoids the liquid level being too low.

In addition, the design of constructing the connector 133 as a liquid level probe enables the connector 133 to simultaneously perform the functions of detecting the liquid level and fixing the first filter screen 131, so that the number of parts can be reduced, the product structure can be simplified, the assembly difficulty can be reduced, and the assembly efficiency can be improved.

Further, a temperature probe may be provided within the brewing cup 12 (and may also be integrated into the connector 133 configured as a liquid level probe) to sense the temperature of the liquid within the brewing cup 12, the temperature probe being electrically or signally connected to the controller 50, and the controller 50 being operable to control the air pump 30 in conjunction with the sensed liquid temperature. In particular, the temperature of the liquid may affect the brewing effect, especially if certain materials have a more precise range of brewing temperatures, such as those required to maintain the temperature of the liquid above 94 ℃. At this time, a corresponding control program can be written in the controller 50 in advance, when the controller 50 determines that the liquid temperature detected by the temperature probe falls out of the lower limit of the pre-stored temperature range, the air pump 30 can be opened and closed intermittently, and for the case that the air pump 30 includes the air suction pump 31 and the air discharge pump 32, the air discharge pump 32 and the air suction pump 31 can be started alternately, so that low-temperature liquid is discharged, liquid meeting the temperature requirement is sucked again, and the brewing effect can be ensured. Specifically, the lower limit of the temperature range when only one air pump 30 is provided may be larger than the lower limit of the temperature range when both the suction pump 31 and the exhaust pump 32 are provided to stop the suction as early as possible.

In some embodiments, as shown in fig. 6 and 7, the connecting member 133 at least partially protrudes from a side surface of the first screen 131 facing away from the cap 122; and/or the first screen 131 is made of a conductive material.

In these embodiments, the liquid level can be directly detected using the connector 133 by having the connector 133 at least partially protrude from the first screen 131. The area of first filter screen 131 is relatively great, and in connecting piece 133 direct contact, through making first filter screen 131 possess electric conductive property, for example first filter screen 131 and connecting piece 133 all adopt the metal material, can realize electric connection through closely cooperating first filter screen 131 with connecting piece 133 as the liquid level probe, also can detect the signal of telecommunication when the liquid level in brewing cup 12 rises to the height that contacts with first filter screen 131, make first filter screen 131 possess the ability that detects the liquid level, help increasing the reliability that the liquid level detected. Generally speaking, when the connecting member 133 does not protrude from the cap 122 and the first filter screen 131 is made of a conductive material, the liquid level detection can be realized by the contact between the first filter screen 131 and the liquid; when the connecting piece 133 protrudes from the cup cover 122, if the first filter screen 131 is not conductive, the liquid level can be detected by the connecting piece 133, and if the first filter screen 131 is conductive, the connecting piece 133 and the first filter screen 131 can be simultaneously used for being conductive, so that the reliability of liquid level detection is improved, the positioning of the first filter screen 131 can be realized by the connecting piece 133, the assembly convenience of the first filter screen 131 is facilitated to be improved, and the risk of position movement and falling off of the first filter screen 131 is reduced.
