Reusable ultrasonic sweetness sensing tableware

The present invention is related to the field of tableware, in particular, it is a kind of ultrasonic sweetness that can detect the sweetness state of liquid through ultrasound and can directly prompt the user to know, so as to help the user to grasp the reusable ultrasonic sweetness of the daily intake of sugar. Measure tableware.

With the rise of environmental awareness in recent years, disposable disposable tableware has gradually been replaced by reusable tableware structures. Through reusable environmentally friendly tableware, the amount of garbage produced in life can be greatly reduced, thereby reducing the environmental impact. Destruction.

On the other hand, in the era of knowledge explosion, the concept of health care has gradually become popular, and people have gradually begun to pay attention to the impact of food, clothing, housing and transportation in daily life on physical health.

The existing solutions generally involve people who use another sugar content meter to measure liquids, or search the Internet for the relationship between the amount of sugar and the burden on the body. Various hand-held brix meters use the refractive index change state of light to penetrate liquids of different concentrations to obtain the precise brix values of the liquid. However, for the general public, it costs money and needs to be carried with them. Only carry this article to measure the liquid you drink, which causes great inconvenience. And back to the question of how to let the public know how much sugar they have ingested on the body, the brix meter can only tell the public how much sugar the measured liquid has, but it cannot let the public know whether the sugar content will affect the body. There is a bad influence or the extent of the influence, so this inconvenience and deficiency cannot be effectively solved.

Reference information.

In order to enable your reviewer to clearly understand the content of the present invention, please refer to the following description and drawings.

Please refer to Figures 1 to 2B, which are a schematic block diagram of an embodiment of the present invention and a schematic diagram of each application. The present invention discloses a reusable ultrasonic sweetness sensing tableware that can detect the sweetness of liquid in a container 9 and includes a tableware body 10 and a detection component 11. The container 9 can be a beverage can, such as an iron can, a milk box-like structure, or a cup structure with an open top side.

The tableware main body 10 is used for eating or drinking beverages, and can be leaned against or positioned with the container 9. Preferably, the tableware body 10 can be a straw, chopsticks, spoon, cup lid, or fork that can be used by itself. More specifically, the tableware main body 10 can be divided into a use area 101 and a non-use area 102. The use area 101 refers to the area where the user needs to contact food or drink when using the tableware main body 10. The container 9 is a fixed area against each other, and the non-use area 1022 is another area of the tableware body 10, such as a part for holding. In this embodiment, the tableware body 10 is a spoon as an example. The detection component 11 is arranged on the tableware main body 10, and when the tableware main body 10 and the container 9 are abutted or positioned, there is an air medium between the tableware main body 10 and the liquid, which is in a non-contact state, thereby preventing the liquid Direct contact causes damage to the detection component 11. The detection component 11 includes a radio frequency unit 111, an echo receiving unit 112 and a processing module 114. The radio frequency unit 111 is used for emitting one of the penetrating liquid detection ultrasonic waves toward the inner wall surface of the container 9 to form a liquid surface reflection ultrasonic wave and at least one wall surface reflection ultrasonic wave. The echo receiving unit 112 is configured to receive the liquid surface reflected ultrasonic wave and the wall surface reflected ultrasonic wave, wherein the liquid surface reflected ultrasonic wave and the wall surface reflected ultrasonic wave are respectively corresponding to the time point received by the echo receiving unit It has a return time value, and the return time value corresponding to the ultrasonic wave reflected by the liquid surface is smaller than the return time value corresponding to the ultrasonic wave reflected on the wall surface.

The processing module 114 is telecommunications connected to the radio frequency unit 111 and the echo receiving unit 112, and the processing module 114 includes a filtering unit 1141. The processing module 114 receives the liquid surface reflected ultrasonic wave and the wall surface reflected ultrasonic wave. The return time value corresponding to the sound wave, and the return time value corresponding to the ultrasonic wave reflected on the liquid surface is filtered through the filter unit 1141, and only the return time value corresponding to the ultrasonic wave reflected on the wall surface is captured , And perform arithmetic processing, and then compare the result of the arithmetic processing with a relation table of sweetness and return status, and then produce a sweetness detection result. The calculation processing mentioned here refers to the processing or calculation of the information, and a better calculation processing method is to calculate the return time value of the ultrasonic wave reflected by the wall and the preset distance information, and then Compare with the relationship table of sweetness and return state, because when the ultrasonic sweetness sensing tableware is chopsticks, spoons and other tableware types, in principle, if the distance needs to be used for calculation processing, it will be caused by the habits of the application. One end of the tableware directly abuts against the bottom of the inner wall of the container 9, so it can be directly calculated by combining the information of the preset distance from the bottom of the tableware to the detection component and the return time value. Further, the ultrasonic sweetness sensing tableware may further include a prompting component 12, which is disposed on the tableware body 10 and is telecommunications connected to the processing module 114. After the processing module 114 generates the sweetness detection result A driving signal corresponding to the level of sweetness is formed and transmitted to the prompt component 12, and the prompt component 12 has at least a low-sweetness prompt mode and a high-sweetness prompt mode to execute the low-sweetness prompt mode according to the drive signal Or the high sweetness prompt mode.

Further, in order to improve measurement accuracy, the detection component 11 may further include a distance measuring unit 113, which is telecommunications connected to the processing module 114 and used to measure the distance to the inner wall of the container 9 A distance value for the processing module 114 to perform calculations. Preferably, the distance measuring unit 113, the radio frequency unit 111, and the echo receiving unit 112 are arranged in parallel and have equal distances from the inner wall surface of the container 9 respectively. And here the distance value obtained by the distance measuring unit 113, if the distance measuring unit 113, the radio frequency unit 111, and the echo receiving unit 112 are respectively equal to the inner wall surface of the container 9, then the distance value is Refers to the distance between the distance measuring unit 113 and the inner wall of the container 9; if the distance measuring unit 113, the radio frequency unit 111, and the echo receiving unit 112 are not equal to the bottom surface of the container 9, the distance measuring unit 113 performs a distance compensation calculation based on the setting gap between itself and the echo receiving unit 112 and the radio frequency unit 111 to generate the distance value. Preferably, in this embodiment, the radio frequency unit 111 emits the detection ultrasonic wave toward the inner wall area of the bottom of the container 9 as an example. Therefore, the distance measuring unit 113 measures the distance between it and the bottom of the container 9 The distance between the inner wall surface area and the distance measurement unit 113 can be an infrared sensor or a laser sensor to use the infrared principle or laser principle for distance measurement. Of course, the distance measurement unit 113 can also be other Electronic components for distance measurement. The radio frequency unit 111 and the echo receiving unit 112 can be integrated as the same ultrasonic transducer, and the effect of receiving and transmitting ultrasonic waves can be achieved through a single ultrasonic transducer, thereby reducing product cost. In addition, in addition to the distance measuring unit 113 for measuring the inner wall surface of the container, the detecting assembly 11 can also be further provided with a liquid level distance measuring unit to know the liquid level in the container 9 and the detecting unit. The distance of the component 11 is measured and transmitted to the processing module 114 for calculation with more detection information to improve the accuracy of the calculated result.

In this way, the ultrasonic sweetness sensing tableware system can use a filtering mechanism to filter out the data that affects the judgment first, and then the return time value to be captured is combined with the distance value to perform arithmetic processing, and according to the sweetness The content of the state relationship table is returned to detect the sweetness of the liquid. It is the result of at least two kinds of high sweetness or low sweetness for the human body, and the result is used by the prompt component 12 to use the high sweetness. The sweetness prompt mode or the low sweetness prompt mode allows the user to know. It should be noted that the high sweetness and low sweetness defined here refer to whether the sweetness state is high or low in terms of the burden or impact on the human body. It does not refer to the amount of sugar contained in the liquid. , The user can know whether the current drinking liquid will cause too much burden on the body through the ultrasonic sweetness sensing tableware.

It should be noted that the present invention is not a traditional ultrasonic detection component specifically used to measure the composition of objects, but on the tableware structure necessary for eating, a component structure that can be used to detect the sweetness of liquid is designed. This concept is currently It is an unseen design concept. Furthermore, when the tableware body 10 still needs to be used by the user to perform general eating actions, how to set up the detection component 11 is another problem that needs to be overcome. Combining the above requirements, The inventor of the present invention proposed a reusable ultrasonic sweetness sensing tableware as described in the present invention after several ideas. In addition, the present invention is based on ultrasonic technology to detect the sweetness state, but the ultrasonic sweetness sensing tableware of the present invention is to quickly and intuitively inform the user of the sweetness state of the detected liquid. Rather than knowing exactly how much sugar content (ie, sugar content) the liquid contains, even if the user can be told to detect the sugar content of the liquid in the prior art, the user still has no way to know the sugar content of the liquid. If there is a burden on the body after drinking, such as telling the user that the sugar content of the liquid is 20, the user still cannot know whether it will have a major impact on the body after drinking. Therefore, the conventional ultrasonic detection technology does not imply It reminds the user of the effect of the burden on the body after drinking the liquid. At the same time, the design of the present invention also simultaneously considers the production cost and manufacturing difficulty. Therefore, the present invention and the past pursuit of technology and products that improve the accuracy of ultrasonic detection are very different in terms of design concepts. The technology of sonic detection means that the present invention does not have the patent requirements, and the design motivation of the present invention and the achievable notification effect must be considered as a whole. In the past technology that uses ultrasonic waves for detection, in order to avoid affecting the detection results, it is generally performed by directly pressing and touching the object to be tested or placing the ultrasonic component in the liquid. However, the direct contact method is only suitable for solid objects to be tested, so it is impossible to apply to the present invention. The method of placing the ultrasonic component in the liquid will easily cause damage to the ultrasonic component and shorten the service life. Therefore, the present invention adopts the aforementioned structural design, and does not choose to install the detection component 11 in the area where the tableware body 10 is against or is positioned in the container 9 when it is in contact with the liquid, which can effectively prevent the liquid from interacting with each other. The detection component 11 causes damage, and the ultrasonic sweetness sensing tableware of the present invention is the first to return the effect of the echo that is not transmitted to the inside of the liquid but only reflected by the liquid surface. The liquid surface reflected ultrasonic wave and its information received by the echo receiving unit are filtered out, and then only the wall surface reflected ultrasonic wave and its information that are actually returned through the liquid are analyzed and compared to generate the driving signal. It can effectively avoid the influence of other media on the detection.

Preferably, the sweetness and return state relationship table is stored in the processing module 114, and the sweetness and return relationship comparison table has complex concentration information and complex wave velocity information, and the concentration information is related to the The wave speed information corresponds to each other; when the distance value and the return time value are calculated to obtain a return wave speed, the processing module 114 compares it with the wave speed information, and then compares it with the wave speed information Corresponding to the concentration information, a weight percentage concentration value of the corresponding liquid is obtained, and the driving signal corresponding to the sweetness level is generated according to the size of the weight percentage concentration value. In other words, the ultrasonic sweetness sensing tableware is based on the echo wave speed of the ultrasonic wave reflected by the wall surface, and after comparing with the sweetness and return state relationship table, the weight corresponding to the echo wave speed can be known. What is the percentage concentration value, and then confirm the sweetness state of the tested liquid according to the weight percentage concentration value. When the weight percentage concentration value is larger, the sweetness of the liquid will be higher, and vice versa. When the concentration value is smaller, the sweetness of the liquid is lower. According to this, the sweetness state of the liquid can be quickly detected through the relationship between the transmission speed and the concentration, and the user intuitively informs the user that the sweetness state will be high or low after drinking. Another way is that the sweetness and return state relationship table can include information about the relationship between ultrasonic return time and sweetness at various distances. In other words, when the processing module 114 receives the distance value and the return value After transmitting the time value, according to the content of the sweetness and return state relationship table, within a certain distance range, when the ultrasonic return time is, the sweetness state of the liquid will be high or low As a result, the driving signal is generated accordingly.

Further, for a finer segmented sweetness state, the prompt component 12 can be made to include a medium sweetness prompt mode. When the weight percentage concentration value is less than 10%, the driving signal drives the prompt component 12 to execute The low sweetness prompt mode; when the weight percentage concentration value is greater than 10% and less than 38%, the driving signal drives the prompt component 12 to execute the medium sweetness prompt mode; when the weight percentage concentration value is greater than 38%, the drive The signal drives the prompt component 12 to execute the high sweetness prompt mode. This is to disclose a better standard of sweetness segmentation. Generally speaking, when the liquid concentration is less than 10%, the sweetness of the liquid will be lower on the human body. Therefore, when the liquid is ingested, there is less need to worry about excessive sugar content. problem. When the concentration of the liquid rises to 38%, the liquid within this concentration range will begin to cause a greater burden and impact on the human body, and the ultrasonic sweetness sensing tableware can instantly inform The user should not ingest excessive amounts of this liquid, so as not to cause metabolic burden on the body. When the liquid concentration is higher than 38%, it is a type of liquid that is not recommended for drinking. This kind of liquid is too sweet, once drinking it will cause the user's body to consume too much sugar, which will cause adverse effects.

Regarding the warning action to the user, the reminder module 12 can notify the user through such as sound, light, vibration, screen display, or through wireless transmission, and can notify the user through mobile devices, display devices, etc. The sweetness state, for example, the prompt module 12 can be provided with a buzzer to inform the user of the detected sweetness state through different sound states, or the prompt module 12 can include a display screen. The user is notified by displaying text, numbers, or patterns on the screen, or as described in this embodiment, in order to make the prompt component 12 have at least one LED light 121, and when the low sweetness prompt mode is executed , The LED light 121 displays a first light color; when the medium sweetness prompt mode is executed, the LED light 121 displays a second light color; when the high sweetness prompt mode is executed, the LED light 121 displays a The third light color; wherein the first light color, the second light color and the third light color are different from each other. According to this, the user can intuitively inform the user whether the liquid is suitable for drinking and whether it will cause an excessive burden on the human body through different light colors. For example, when the prompt component 12 executes the low sweetness mode, the first light color system may be green, when the medium sweetness mode is executed, the second light color may be yellow, and when the high sweetness mode is executed, it may be Make this third light color red.

In order to make the tableware main body 10 abut or be positioned on the container 9 more stably, the tableware main body 10 may be further provided with a latch 103 to make the tableware main body 10 and the edge of the container 9 be locked and fixed to each other. The detent portion 103 can be a convex block with a concave portion or a bent stop rib, etc., so that when the tableware body 10 is placed in the container 9, the detent portion 103 can be hooked or snapped against In this embodiment, the edge of the container 9 is illustrated by taking the latching portion 103 as a convex structure with a concave portion as an example.

In application, as shown in Figures 2A and 2B, after the user puts the tableware main body 10 in the container 9, the detection assembly 11 can be activated, and the radio frequency unit 111 sends the radio frequency toward the wall of the container 9 To detect ultrasonic waves, take the radio frequency unit 111 emitting ultrasonic waves toward the bottom surface of the container 9 as an example, and the distance measuring unit 113 measures the distance between the detection assembly 11 and the bottom surface of the container 9. Since there is the air medium between the detecting component 11 and the liquid, when the detecting ultrasonic wave is emitted and contacts the liquid surface, the ultrasonic wave reflected by the liquid surface will be formed and transmitted back to the detecting ultrasonic wave. The component 11 is received by the echo receiving unit 112, and the remaining detected ultrasonic energy is continuously transferred to the inside of the liquid until it hits the bottom of the container 9 to form the wall reflected ultrasonic wave, and is transmitted back to the The detection component 11 is received by the echo receiving unit 112. At this time, if the energy of the detected ultrasonic wave is sufficient, the echo receiving unit 112 will continue to receive at least one reflected ultrasonic wave from the wall surface. After the processing module 114 receives the distance value and the return time value corresponding to the liquid surface reflected ultrasonic wave and the wall surface reflected ultrasonic wave, respectively, it transmits the return time corresponding to the liquid surface ultrasonic wave through the filter unit 1141 The time value is filtered out, and only the return time value corresponding to the wall ultrasonic wave is captured, and then it is processed with the distance value, and the calculation result is compared with the sweetness and return state relationship table The drive signal is formed. After the comparison of the processing module 114, the ultrasonic sweetness sensing tableware can know the sweetness state of the liquid in the container 9, and the prompting component 12 is made to correspond to the driving signal according to the corresponding sweetness level. Mode operation, such as Fig. 2B, is an example of the LED 121 of the prompt component 12 taking the low-sweetness prompt mode to emit light of the first light color that is green.

Please continue with Figure 3, which is an application schematic diagram of another implementation aspect of an embodiment of the present invention. The ultrasonic sweetness sensing tableware can be designed as a cup in addition to a spoon as shown in Figure 2 The cover structure is arranged on the top side edge of the container 9 to abut against the cover. Similarly, when the ultrasonic sweetness sensing tableware is a cup lid, the sweetness sensing application is also to drive the radio frequency unit 111 to emit the detection ultrasonic wave toward the liquid, and the ranging unit 113 detects the The distance between the detection component 11 and the bottom surface of the container 9 is detected. Then, after the echo receiving unit 112 sequentially receives the reflected ultrasonic waves returned at different time points and the corresponding return time values, the filtering unit 1141 of the processing module 114 will soon return the first The return time value is filtered out, the second and subsequent return time values are combined with the distance value for calculation processing, and then the calculation results are compared with the sweetness and return relationship table to form the drive signal. The prompt component 12 executes the corresponding prompt mode according to the driving signal.

Please refer to FIG. 4, which is a block diagram of a second implementation aspect of the first embodiment of the present invention. In this implementation aspect, the processing module 114 has a sweetness control unit 1142 and a confirmation unit 1143. The sweetness control unit 1142 has a built-in daily sweetness intake upper limit, the confirming unit 1143 is for receiving a storage signal, and the processing module 114 compares the calculation result with the sweetness and return status table After the driving signal is generated by comparison, if the confirmation unit 1143 receives the storage signal, the measured sweetness result is stored in the sweetness control unit 1142 to form an intake record value. When the unit 1142 stores the intake record value, the sweetness control unit 1142 subtracts the intake record value from the daily sweetness intake upper limit value to obtain a surplus sweetness intake value, and can further use the prompt The component 12 prompts the surplus sweetness uptake value. Accordingly, the ultrasonic sweetness sensing tableware can not only inform the user of the detected liquid sweetness state through ultrasonic detection, but also has the function of recording the total sweetness state of the user's drinking liquid.

For example, the daily sweetness intake upper limit of the sweetness control unit 1142 can be a simple number or grade data. For example, it can be set to 8, and the detection component 11 is for liquid sweetness. After the degree is measured, the user can determine whether the result of the comparison between the calculation processing result and the sweetness and return state relationship table needs to be stored in the sweetness control unit 1142 based on whether or not to drink the liquid as a storage basis. For example, although the user measures the liquid in the container 9, but does not actually drink it, there is no need to store the measurement result at this time. If the user also drinks the liquid after the measurement, then By pressing a button of the detecting component 11, the confirmation unit 1143 can receive the storage signal, and the result of the comparison between the calculation processing result and the sweetness and return status relation table can be stored in the The intake record value is formed in the sweetness control unit. Wherein, the intake record value corresponds to a value that can be determined based on the sweetness level of the liquid measured by the detecting component, for example, the higher the sweetness, the higher the intake record value. For example, when the calculation result is compared with the sweetness and return state relationship table and it is found that the liquid system detected at this time is of low sweetness, the ingestion record value formed by recording it can be set as 2. If the calculation result is compared with the sweetness and return state relationship table and it is found that the liquid system detected at this time is of high sweetness, the intake record value formed by recording it can be set to 4.

After the sweetness control unit 1142 stores the intake record value, the sweetness control unit 1142 subtracts the intake record value from the daily sweetness intake upper limit value to obtain the remaining sweetness intake value, For example, the sweetness control unit 1142 stores the intake record value of 4 and subtracts it from the daily sweetness intake upper limit value of 8, to obtain the excess sweetness intake value of 4. , And prompt the user through the prompt component 12. Alternatively, when the sweetness control unit 1142 stores two or more of the intake record value, the sweetness intake control unit 1142 first adds up the intake record value, and then adds it to the daily sweetness intake upper limit The value is subtracted to obtain the surplus sweetness intake value, based on which the user’s daily intake of liquid sweetness is controlled. For example, when the sweetness control unit stores the intake record values of 2 and 4, the excess sweetness intake value is 8-(2+4) and is 2.

Further, in addition to directly prompting the user of the remaining sweetness intake value, when the detection component 11 performs the next measurement, if the intake record value corresponding to the liquid is greater than the remaining sweetness intake value, then the sweetness The degree control unit 1142 sends a warning signal to the reminder component 12, and the reminder component 12 sends a warning action to inform the user that the liquid should not be consumed. Continuing the foregoing example, if the excess sweetness intake value is 2, when the next measurement of the liquid by the detecting component 12 corresponds to the intake record value of 4, then the sweetness control unit 1142 issues the warning signal The reminder component 12 is given to the reminder component 12 to issue a warning action to inform the user that the liquid should not be consumed anymore, so as to avoid excessive intake of sugar.

Next, please refer to FIG. 5, which is a block diagram of yet another implementation aspect of an embodiment of the present invention. The ultrasonic sweetness sensing tableware further includes a wireless communication module 13, which is telecommunications connected to the detection component 11 for pairing connection with a mobile device 2, and the wireless communication module 13 communicates with the mobile device. After the device 2 is paired, the radio frequency unit 111 can receive a control command from an application program of the mobile device 2 to send out the detection ultrasonic wave, and the processing module 114 can perform measurement through the wireless communication module 13 The obtained sweetness result is transmitted to the mobile device 2 and stored through the application. In this way, the user can remotely control the action of the ultrasonic sweetness sensing tableware through the mobile device 2, and the sweetness results obtained after each liquid detection can be stored in the application one by one. And it can be beneficial for users to control the sweetness of daily drinks. For example, if the user detects and drank three liquids on the day, the individual sweetness status of these three liquids can be stored in the application, and the user can check it later At the time, you can know how much sweetness the liquid has been drunk during the day. More specifically, due to practical applications, the user may use the ultrasonic sweetness sensing tableware to detect many liquids, but not drink every detected liquid. Therefore, in the part of storing the sweetness results, it can be further improved. The sweetness detection result of the drinking liquid is actually stored through the confirmation mechanism. The confirmation mechanism can be implemented by pressing the confirmation button on the ultrasonic sweetness sensing tableware, or clicking the confirmation storage on the mobile device 2 . Preferably, the wireless communication module 13 can communicate with the mobile device 2 using Bluetooth communication technology, and has the advantages of low power consumption and stable transmission.

Furthermore, the application can also have a built-in daily sweetness intake upper limit, so as to calculate and control the sweetness status of the user's drinking liquid based on the sweetness results stored in the application. Same as the foregoing, for example, the daily sweetness intake limit can be set to 10, and following the example in the previous paragraph, if the user detects and drank three liquids on the same day, the corresponding intake records can be obtained based on the sweetness results. According to the calculation of the intake record value and the daily sweetness intake upper limit, it can be known how much sweetness level the user can drink after drinking the three liquids. For example, the intake record values are respectively If it is 2, 3, 3, the sweetness of the liquid that the user can drink today, that is, the surplus sweetness intake value, may only have the liquid corresponding to the intake record value of 2. At this time, the ultrasonic sweetness sensing tableware can directly prompt the surplus sweetness intake value through the prompt component 12, or through the application program of the mobile device 2, further, in the ultrasonic sweetness sensing After the tableware is measured for the next time, if the intake record value corresponding to the liquid measured this time exceeds the marginal sweetness intake value, the ultrasonic sweetness sensing tableware can also issue a warning that it is not recommended to drink through the prompt component 12.

And when the ultrasonic sweetness sensing tableware can be connected to the mobile device communication 2, a preferred implementation state is that the sweetness and return state relationship table is stored in the processing module 114, and the sweetness and sweetness The return relationship comparison table has complex concentration information and complex wave velocity information, and the concentration information corresponds to the wave velocity information; wherein when the processing module 114 processes the distance value and the return time value to obtain a After returning the wave velocity, the processing module 114 compares it with the wave velocity information to obtain a first weight percentage concentration value, and at the same time transmits the returned wave velocity to the application program, so that the application program depends on the The returned wave speed is compared with a cloud data to obtain a second weight percentage concentration value and transmit it to the processing module 114, and when the difference between the first weight percentage concentration value and the second weight percentage concentration value is less than a set value , Generate the driving signal corresponding to the sweetness level according to the magnitude of the first weight percentage concentration value. In this way, the accuracy of sweetness sensing can be improved by a double comparison method. Preferably, the setting value can be between 3 and 5, so as to have a better basis for comparison. If it is found that the difference between the first weight percentage concentration value and the second weight percentage concentration value is greater than or equal to the set value, the ultrasonic sweetness sensing tableware will perform the measurement again.

Under this structure, the prompt component 12 can also include a medium sweetness prompt mode. When the first weight percentage concentration value is less than 10%, the driving signal drives the prompt component 12 to execute the low sweetness prompt mode. ; When the first weight percentage concentration value is greater than 10% and less than 38%, the driving signal drives the prompt component 12 to execute the mid-sweetness prompt mode; when the first weight percentage concentration value is greater than 38%, the driving signal is The prompt component 12 is driven to execute the high sweetness prompt mode. And the prompt component 12 has at least one LED lamp 121, and when the low sweetness prompt mode is executed, the LED lamp 121 displays a first light color; when the medium sweetness prompt mode is executed, the LED lamp 121 displays A second light color; when the high sweetness prompt mode is executed, the LED lamp 121 displays a third light color; wherein the first light color, the second light color, and the third light color are different from each other. For other related detailed technical features, please refer to the foregoing paragraphs for the combination.
