Please refer to Figure 1 and Figure 2 together. Figure 1 is a block diagram of the first embodiment of the coffee brewing device of the present invention. Figure 2 is a block diagram of the first embodiment of the coffee brewing device of the present invention. The coffee brewing device 1 provided by the present invention is used for brewing instant coffee brewing bags such as instant black coffee, two-in-one brewed coffee or three-in-one brewed coffee.

As shown in the figure, the coffee brewing device 1 in this embodiment of the present invention mainly includes a brewing body 10, an ultrasonic oscillation unit 21, a first sensing module 31 and a control module 40.

The structure of the brewing body 10 is generally similar to that of a mug that is generally known or commonly used by the general knowledgeable person in the art. The material of the brewing body 10 is usually pure porcelain, glazed porcelain, glass, stainless steel or specific plastic, etc. In this embodiment of the present invention, the brewing body 10 has a brewing accommodating space 11 and a component accommodating space 12 separated from top to bottom. The brewing accommodating space 11 may have an opening for pouring the contents of the instant coffee brewing bag and a liquid such as hot water, so that the contents of the instant coffee brewing bag and the hot water form a brewing liquid and are accommodated in the brewing accommodating space 11.

The ultrasonic oscillator 21 may be an ultrasonic oscillator that is well known or commonly used by a person skilled in the art. Preferably, the ultrasonic oscillator 21 may be a micro ultrasonic oscillator. The ultrasonic oscillator 21 is disposed in the component accommodating space 12. The ultrasonic oscillator 21 is configured to generate an ultrasonic oscillation 211 to the brewing accommodating space 11. That is, the ultrasonic oscillator 21 can cause the brewing liquid in the brewing accommodating space 11 to generate ultrasonic oscillation 211. In this way, the contents of the instant coffee brewing bag and hot water can be mixed into a brewing liquid under conditions similar to stirring.

The first sensing module 31 is disposed in the foaming accommodating space 11. The first sensing module 31 is configured to sense the foaming liquid in the foaming accommodating space 11 to generate a first sensing signal 311. The control module 40 is disposed in the component accommodating space 12 and is electrically connected to the ultrasonic oscillation unit 21 and the first sensing module 31. The control module 40 controls the ultrasonic oscillation unit 21 to operate or stop according to the first sensing signal 311.

It is worth mentioning that the first sensing module 31 can be set at a position higher than the water surface of the foaming liquid to sense the color of the foaming liquid to generate the first sensing signal 311. The control module 40 compares whether the first sensing signal 311 matches a reference color 52. When it does not match, the control module 40 continuously controls the ultrasonic oscillation unit 21 to operate, and when it matches, controls the ultrasonic oscillation unit 21 to stop. In addition, in different embodiments, the first sensing module 31 can also sense the fluid viscosity or particles of the foaming liquid to generate the first sensing signal 311. At this time, the first sensing module 31 can be set at the position of the water surface of the foaming liquid or at a position lower than the water surface of the foaming liquid.

It is also worth mentioning that the coffee brewing device 1 includes a storage 50, which is electrically connected to the control module 40. The storage 50 stores a plurality of reference colors 52, each of which corresponds to instant coffee bags of different brands or instant coffee bags of different models of the same brand.

The coffee brewing device of the present embodiment of the present invention can be used to compare the brewing liquid by continuously using the ultrasonic oscillation unit to generate ultrasonic oscillation until the content of the instant coffee brewing bag is judged to be properly dissolved and saturated in the liquid such as hot water according to the color, thereby avoiding the influence of uneven stirring on the taste and flavor of the instant coffee brewing bag. In addition, the reference color corresponds to instant coffee bags of different brands or instant coffee bags of different models of the same brand, such as instant black coffee, two-in-one brewed coffee or three-in-one brewed coffee, and the reference colors are different. For example, three-in-one brewed coffee of different brands also has different reference colors due to the amount of coffee powder. By the way, regarding the configuration of the reference color, a computing device may process a large amount of historical data through a machine learning algorithm and find the pattern of the data to adjust and set the most appropriate reference color.

Please refer to Figure 3 and Figure 4 together. Figure 3 is a block diagram of the second embodiment of the coffee brewing device of the present invention. Figure 4 is a block diagram of the second embodiment of the coffee brewing device of the present invention. In this embodiment, the configuration and operation of the components with the same component symbols are the same or similar to the above-mentioned embodiments, and the same or similar parts will not be repeated here.

As shown in the figure, in this embodiment of the present invention, the main difference from the aforementioned embodiment is that the storage device 50 stores a plurality of brewing scripts 51. Each brewing script 51 corresponds to an instant coffee bag of a different brand or an instant coffee bag of a different model of the same brand, and each brewing script 51 includes the reference color 52, a vibration frequency 53 and a vibration intensity 54, that is, instant coffee bags of different brands or instant coffee bags of different models of the same brand have different reference colors 52, vibration frequencies 53 and vibration intensities 54.

The control module 40 controls the ultrasonic oscillation unit 21 to operate or stop according to the reference color 52, the vibration frequency 53 and the vibration intensity 54 according to the brewing script 51 triggered by a control interface 61, and the control interface 61 is set on the brewing body 10 or an electronic device 7 connected wirelessly. When the control interface 61 is set on the brewing body 10, it can be a touch display unit set on the bottom of the cup or near it or a touch display unit with corresponding physical buttons.

The coffee brewing device of the present embodiment of the present invention can be used to compare the brewing liquid, and the ultrasonic oscillation unit is continuously used to generate ultrasonic oscillations at the vibration frequency and the vibration intensity corresponding to the instant coffee bag until the content of the instant coffee brewing bag is judged to be properly dissolved and saturated in the liquid such as hot water according to the color, thereby avoiding the influence of uneven stirring on the taste and flavor of the instant coffee brewing bag. For example, Turkish-style instant coffee, based on its thickness, requires a higher vibration intensity and a corresponding vibration frequency for stirring. By the way, regarding the configuration of the vibration frequency and the vibration intensity, it can be a computing device or the server mentioned later that processes a large amount of historical data through a machine learning algorithm and finds the pattern of the data to adjust and set the most suitable vibration frequency and the vibration intensity; or, as further explained later, the foaming script formed by the previous user's attempt is used and then stored on the server for people to download and use.

In addition, since different instant coffee bags have different or different ingredients and total amounts of contents, the required liquid temperature and liquid amount are also different. Based on this, the coffee brewing device 1 includes a second sensing module 32, a third sensing module 33 and a prompt unit 22 electrically connected to the control module 40.

Each of the brewing scripts 51 includes a water level value 55. The second sensing module 32 is disposed in the brewing accommodating space 11; the second sensing module 32 is configured to sense the water level of the brewing liquid in the brewing accommodating space 11 to generate a second sensing signal 321. The control module 40 determines whether the second sensing signal 321 meets the water level value 55, so as to control the prompt unit 22 to generate a first prompt message when the water level of the brewing liquid gradually approaches the water level value 55, and to control the prompt unit 22 to generate a second prompt message when the water level of the brewing liquid meets the water level value 55. For example, the prompt unit 22 can be a light-emitting unit or a sound-emitting unit, and when the water level of the foaming liquid gradually approaches the water level value 55, the prompt unit 22 can emit orange light or red light, or a sound with a shorter or longer interval as the first prompt message; in addition, when the water level of the foaming liquid gradually approaches, it can also gradually change from red to orange, or the interval can be changed from a shorter time to a longer time or from a longer time to a shorter time. Furthermore, when the water level of the brewing liquid meets the water level value 55, the prompt unit 22 can emit a green light or a long sound as a second prompt message; in addition, the green light or the long sound can stop or turn off after a period of time.

Each of the brewing scripts 51 includes a temperature value 56; the third sensing module 33 is configured to sense the temperature of the brewing liquid in the brewing accommodating space 11 to generate a third sensing signal 331. When the control module 40 determines that there is a difference between the third sensing signal 331 and the temperature value 56 or the temperature difference is too large, it can first control the prompt unit 22 to emit a related prompt sound to remind the user. Then, the control module 40 adjusts or corrects the vibration frequency 53 and the vibration intensity 54 according to the difference between the third sensing signal 331 and the temperature value 56. Incidentally, regarding the adjustment or correction of the vibration frequency 53 and the vibration intensity 54, a computing device may process a large amount of historical data through a machine learning algorithm and find out the pattern of the data to obtain the adjusted or corrected vibration frequency and the vibration intensity.

It is worth mentioning that the coffee brewing device 1 includes an application 60, which is set in the electronic device 7, and the application 60 uses the electronic device 7 to display the control interface 61. The electronic device 7 is, for example, a smart phone, a tablet computer, etc., and the electronic device 7 is electrically connected to the control module 40 by means of Bluetooth or WIFI. That is, although not specifically mentioned, the coffee brewing device 1 may include a wireless communication module, a power supply unit for supplying power, or a charging interface for charging the power supply unit, etc., which are commonly known or used by people of ordinary skill in the art.

In addition, the control module 40 or the application 60 is electrically connected to a server 8. The server 8 stores a plurality of flush scripts 51; therefore, the control module 40 can download the flush script 51 and store it in the memory 50 or replace the flush script 51 in the memory 50, or the application 60 can download the flush script 51 and store it in the memory 50 or replace the flush script 51 in the memory 50 through the control module 40.

It is worth mentioning that the application 60 includes a manual interface 62, which is configured for the user to execute a script program 63. In the script program 63, the manual interface 62 is for the user to set the brand and model of the instant coffee bag. The application 60 records the reference color 52, the water level of the brewing liquid, the temperature of the brewing liquid, and the vibration frequency 53 and the vibration intensity 54 controlled by the manual interface 62 to store them as the brewing script 51. The application 60 stores the brewing script 51 generated by the script program 63 in the memory 50. Therefore, the application 60 can store the bubble script 51 generated by the script program 63 to the server 8.

That is to say, you or other users form the best brewing method after trying, and then upload the brewing script to the server for others to download and use, especially the brand and/or model of instant coffee packets that other users try for the first time, or the brewing script of the brand and/or model of instant coffee packets that are not originally stored in the server; this method greatly increases the convenience for both the production end and the user end. By the way, the production end can also use the brewing scripts of many users to process a large amount of historical data through machine learning algorithms, and find the data pattern to obtain the relevant parameters or correction parameters that are most suitable for the corresponding brand and/or model of instant coffee packets.

The above description is for illustrative purposes only and is not intended to be limiting. Any equivalent modification or change made to the invention without departing from the spirit and scope of the invention shall be included in the scope of the patent application attached hereto.
