The invention relates to the technical field of brewing devices, in particular to a fountain-type brewing device with an automatic water supply function.
As is commonly known, people use brewing devices when drinking tea, milk powder and coffee in daily life. Wherein, tea brewing devices are the most common ones, most of which adopt a brewing basket to contain tea or other substances to be brewed, and the brewing basket rises and falls in water to brew tea or other substances; however, such a brewing manner often leads to non-uniform brewing. Some of these brewing devices adopt a rotary motor sleeved with an impeller stirring head for stirring to make brewing more uniform; however, it is extremely inconvenient for users to clean such brewing devices.

As shown in
Embodiment 1: This embodiment provides a fountain-type brewing device with an automatic water supply function, comprising a device body 1, wherein the device body 1 is provided with a brewing container 2, a brewing frame 4 is mounted in the brewing container 2 by means of a locking element 3, a main passage 5 and at least one branched passage 6 communicated with the main passage 5 are disposed in the brewing frame 4, a brewing basket 7 is disposed on the brewing frame 4, a pipe outlet 8 of the main passage 5 is disposed in the brewing basket 7, the brewing frame 4 is provided with a guide rod 9 located above the brewing basket 7, the guide rod 9 is provided with a guide cavity 10 communicated with the branched passage 6, and a water outlet of the guide cavity 10 is exactly opposite to the pipe outlet 8 of the main passage 5; and a circuit board 11, a heating plate 12, a power connector 13 and a water pump 14 are disposed in the device body 1, the heating plate 12, the power connector 13 and the water pump 14 are all electrically connected to the circuit board 11, the heating plate 12 is disposed at the bottom of the brewing container 2, a water inlet of the water pump 14 is disposed in the brewing container 2, a water outlet of the water pump 14 is communicated with the main passage 5 by means of a drain joint 15.
The brewing principle of this embodiment mainly lies in that a jet brewing effect is realized by means of opposed water columns. Specifically, when the fountain-type brewing device works, water is injected into the brewing container 2 at first, the power connector 13 is connected to a power source, and the circuit board 11 controls the heating plate 12 to generate heat to heat the water in the brewing container 2; when heated to a preset system temperature, the water in the brewing container 2 will not be heated anymore. The water in the brewing container 2 is pumped and discharged by the water pump 14 into the main passage 5 of the brewing frame 4, part of the water discharged by the water pump 14 flows into the at least one branched passage 6 disposed in the main passage 5, and in this way, the brewing frame 4 is divided into two discharge passages, one of which is consisted of the main passage 5 and the other one is consisted of the branched passage 6 and the guide cavity 10 in the guide rod 9; water in the main passage 5 is sprayed out directly, while water in the branched passage 6 is sprayed out via the guide cavity 10 in the guide rod 9, and the water outlet of the guide cavity 10 is exactly opposite to the pipe outlet 8 of the main passage 5, so water sprayed out of the main passage 5 collides with water sprayed out of the branched passage 6 to form a horizontal spraying surface, which creates a fountain effect to allow water to be evenly sprinkled into the brewing basket 7, thus realizing a fountain-type uniform brewing effect. Water in the brewing basket 7 flows into the brewing container 2 again after flushing the brewing basket 7, water is continuously pumped from the brewing container 2 by the water pump 14 to be used for flushing again to realize cyclic flushing, and finally, uniform and sufficient brewing is completed.
Further, in this embodiment, the brewing frame 4 is detachably mounted in the brewing container 2, and specifically, the brewing frame 4 is locked by the locking element 3. However, the locking element 3 in this embodiment may be of different structures. For example, the locking element 3 may be a magnet 100 for attracting the brewing frame 4 into the brewing container 2, or the locking element 3 may be a buckle for clamping and locking the brewing frame 4 into the brewing container 2, or the locking element 3 may be an internal or external thread for rotatably screwing the brewing frame 4 into the brewing container 2. This embodiment has no limitation in this aspect. The brewing frame 4 is detachably mounted in the brewing container 2, so that brewing frames 2 of different structures may be used when necessary and may be detached to be cleaned.
Further, to prevent other portions of the device body from being contaminated by part of liquid splashing upwards when the water columns collide with each other, the guide rod 9 in this embodiment is provided with a barrier plate 16 located at the water outlet of the guide cavity 10. The barrier plate 16 is able to prevent water from splashing upwards, thus fulfilling a protection effect.
Further, to ensure that users can perform actual operation control easily, the device body 1 in this embodiment is provided with a control switch (not shown) electrically connected to the circuit board 11. Users may press the control switch to transmit instructions to the circuit board 11 to start work.
Further, to prevent large particles from entering the brewing container 2, a filter screen 17 or a filter paper is disposed on the periphery or the bottom of the brewing basket 7 to filter brewed substances, in this embodiment.
Further, to accurately control the water temperature, a temperature sensor 18 is disposed in the brewing container 2 and is electrically connected to the circuit board 11, in this embodiment; and when detecting a set parameter value, the temperature sensor 18 sends an instruction to the circuit board to stop the heating plate from generating heat.
Further, to guarantee normal use of the brewing device, the device body 1 in this embodiment is provided with a lid 19 located at a cavity opening of the brewing container 2 and is also provided with a handle 20 to be held by users.
Further, considering that hot water in the brewing device may splash out because the water pump 14 starts to work before the brewing frame 4 is assembled, the device body 1 in this embodiment is further provided with an induction switch 21 for detecting whether the brewing frame 4 has been assembled, the induction switch 21 is electrically connected to the circuit board 11, and the water pump 14 will not start to work until the induction switch 21 senses that the brewing frame 4 has been assembled. Since the brewing frame 4 is mounted in the brewing container 2 by means of the locking element 3 and the locking element 3 may be mounted in different manners, the induction switch 21 in this embodiment needs to be matched with the installation structure of the locking element 3. For example, if the locking element 3 is a magnet, a Hall switch is used to detect whether the brewing frame 4 has been assembled; or, if the locking element 3 is a buckle or a thread, a micro-switch may be used to detect whether the brewing frame 4 has been assembled. This embodiment has no limitation to the specific type of the induction switch 21.
