Referring to fig. 2, fig. 2 is a schematic flow chart of a fruit and vegetable recommendation-based juicer control method according to an embodiment of the present application.

As shown in fig. 2, the fruit and vegetable recommendation-based juicer control method specifically includes: step S201 to step S205.

S201, receiving body information of a user.

After the user uses the body fat scale, the body fat scale records the body information of the user, the recorded body information of the user is sent to the juicer, and the juicer receives the body information of the user sent by the body fat scale.

In some embodiments, a display screen may be further disposed on the juicer, wherein the display screen may be a touch display screen, a push-button display screen, or other types of display screens. When the juicer receives body information of a plurality of different users, the juicer can display a plurality of different body information on a display screen of the juicer, including weight, body fat percentage, human body water content and the like, so that the user can select the body information. When a plurality of physical information exists, the user can select the fruit and vegetable recommendation needed from the plurality of physical information so as to improve the universality of the juicer in use.

S202, determining the target fruits and vegetables according to the body information.

Wherein the body information includes a body fat rate and a body water content. In addition, the body information may also include weight, bone weight, and the like. And screening various fruits and vegetables according to the body information so as to determine the target fruits and vegetables.

In some embodiments, referring to fig. 3, the determining the target fruit and vegetable according to the body information specifically includes: step S2021 and step S2022.

S2021, determining a first fruit and vegetable set according to the body fat percentage and the fruit and vegetable information table.

The fruit and vegetable information table may be preset, and the information in the fruit and vegetable information table includes the nutrient components of the common fruits and the corresponding numerical values or ratios of the nutrient components, as shown in table 1.

TABLE 1

Among these, the GI value, i.e., the glycemic index, reflects primarily the speed and ability of food to elevate blood glucose compared to glucose, and generally speaking, the higher the food is digested, the higher the GI value, the slower the food is digested, and the lower the GI value. It is generally considered that foods with GI values less than 55 are low GI foods, foods with GI values between 55 and 70 are medium GI foods, and foods with GI values greater than 70 are high GI foods.

The body fat percentage of normal adults is respectively 15 to 18 percent for men and 25 to 28 percent for women. If the body fat rate is too high, the body weight is more than 20% of the normal value, so the obesity can be regarded as obesity, and the obesity is easy to increase the probability of suffering cardiovascular diseases and some chronic diseases. If the body fat rate is too low, below the safe lower line for body fat content, i.e. 5% for men and 13% to 15% for women, dysfunction may result.

Therefore, the fruits and vegetables in the fruit and vegetable information table are screened according to the body fat percentage to obtain a plurality of fruits and vegetables which meet the body fat screening conditions, and the set of the fruits and vegetables which meet the conditions is used as the first fruit and vegetable set. For example, if the body fat percentage is high, fruits and vegetables with low GI values, that is, fruits and vegetables with GI values lower than 55, can be selected to control blood sugar and weight. On the contrary, if the body fat rate is too low, the fruits and vegetables with high GI value can be selected.

S2022, screening the first fruit and vegetable set according to the human body water content and the fruit and vegetable information table to obtain target fruits and vegetables.

And after the first fruit and vegetable set is obtained, screening the first fruit and vegetable set according to the human body water content and the fruit and vegetable information table to obtain the target fruit and vegetable. When the water content in the human body is too low, the metabolic capability of the human body is reduced, thereby possibly causing some diseases, and when the water content in the human body is too high, edema may be caused. Therefore, according to the water content of the human body, if the water content of the human body is low, the fruits and vegetables with high water content can be selected in the first fruit and vegetable set, and conversely, the fruits and vegetables rich in flavone, vitamin C or potassium elements can be selected in the first fruit and vegetable set, so that the body fluid balance is adjusted, and the kidney is helped to clear water.

In some embodiments, the fruit and vegetable recommendation-based juicer control method further comprises: acquiring current season information; the basis according to human water content with the fruit vegetables information table is in first fruit vegetables are concentrated and are screened, include: and screening in the first fruit and vegetable set according to the human body water content, the current season information and the fruit and vegetable information table.

Because under different environment, people's dietary habits may be different, consequently, the fruit that the season was eaten also is different, consequently, can obtain first fruit vegetables collection after, when carrying out the screening of target fruit vegetables according to human water content, combines current season information to filter to the food that makes the screening obtain accords with user's actual life more. For example, when the weather is dry in autumn, some fruits and vegetables with the functions of removing dryness and clearing fire can be screened.

In some embodiments, the types of the target fruits and vegetables obtained by screening can be multiple, and when the types of the target fruits and vegetables are multiple, the multiple target fruits and vegetables can be respectively presented to the user for the user to select.

S203, acquiring the weight of the target fruits and vegetables, the juice yield of the fruits and vegetables and the concentration of the fruits and vegetables determined by a user.

The fruit juice extractor can obtain the fruit and vegetable juice yield of the target fruit and vegetable from the fruit and vegetable information table. Wherein, the fruit and vegetable juice yield is the amount of milliliter of fruit and vegetable juice squeezed from one kilogram of fruit and vegetable without adding water, and the calculation formula is as follows:

wherein Y represents the juice yield of the fruits and vegetables, N represents the pure fruit and vegetable juice amount, and N represents the fruit and vegetable amount.

In addition, can also set up weighing transducer on the fruit juice extractor, put into the fruit juice extractor back at the user with the target fruit vegetables, the fruit juice extractor can be automatically weighed to the target fruit vegetables in the fruit juice extractor to obtain fruit vegetables weight.

When the concentration of the fruit and vegetable juice is obtained, the juicer can determine the optimal drinking concentration according to the target fruit and vegetable, but different users have different tastes, so that the user can modify and set the concentration of the fruit and vegetable juice by himself, and the taste of the obtained fruit and vegetable juice meets the personal taste of the user.

In some embodiments, the concentration of the fruit and vegetable juice determined by the user may be stored, and the number of times that the user performs juice extraction using each concentration of the fruit and vegetable juice is respectively counted, if the user performs juice extraction using the same concentration of the fruit and vegetable juice for multiple times, the concentration of the fruit and vegetable juice is used as a common concentration, and when the user performs juice extraction next time, the common concentration is automatically selected as the concentration of the fruit and vegetable juice, so as to facilitate the operation of the user.

In some embodiments, feedback information of the user may also be received, where the feedback information refers to feedback of the user on whether the obtained concentration of the juice is suitable for evaluation. If the user feeds back that the concentration of the obtained fruit and vegetable juice is lower, the concentration of the fruit and vegetable to be squeezed can be increased in a proper amount when the next time of squeezing is performed, otherwise, if the user feeds back that the concentration of the obtained fruit and vegetable juice is higher, the concentration of the fruit and vegetable to be squeezed can be decreased in a proper amount when the next time of squeezing is performed, so that the use of the user is convenient, and the obtained fruit juice is more in line with the taste of the user.

In some embodiments, referring to fig. 4, the step of obtaining the weight of the target fruit and vegetable specifically includes: s2031 and S2032.

S2031, obtaining the motion information of the user.

The motion information includes, among other things, a motion time, a motion type, and so on. The juicer can be connected with a wearable device of a user, such as a sports bracelet, a mobile phone and the like, or other sports recording software, so as to obtain the sports information of the user from the wearable device or the sports recording software.

S2032, based on an energy calculation formula, calculating energy consumed by a user according to the motion information, and determining the weight of the target fruits and vegetables based on the consumed energy.

The body information sent by the body fat scale received by the juicer includes the weight of the user, so the energy calculation formula can be as follows:

where E represents the energy consumed by the user, W represents the user's weight, T represents the user's exercise time, and K represents the exercise constant.

The motion constant can be different according to different types of user motions. For example, different motion constants may be used for three different aerobic exercises, walking, running and stepping. Based on the energy calculation formula, the energy consumed by the user can be obtained.

In some embodiments, the determining the fruit and vegetable weight of the target fruit and vegetable based on the consumed energy comprises: calculating the required energy of the target fruits and vegetables based on the energy ratio of the target fruits and vegetables and the consumed energy; and calculating the weight of the target fruits and vegetables according to the required energy and the energy components of the target fruits and vegetables.

The energy proportion of the target fruits and vegetables is determined according to Chinese resident dietary guidelines, Chinese resident balanced diet pagoda, Chinese food ingredient tables and the like, and the proportion of the energy required to be supplemented to the total consumed energy of the fruits and vegetables is determined. For example, the energy consumed by human body is 1000kcal, and the energy percentage of the target fruit and vegetable is 30%, so that the required energy of the target fruit and vegetable can be calculated as follows: 1000 x 30% ═ 300 kcal.

After the required energy of the target fruits and vegetables is calculated, the fruit and vegetable information table stores the numerical value of each nutrient component contained in the target fruits and vegetables, so that the juicer can acquire the numerical value of the energy component of the target fruits and vegetables from the fruit and vegetable information table, and the weight of the target fruits and vegetables can be calculated. Wherein, the energy component can be specifically heat.

In the specific implementation process, the weight of the target fruits and vegetables can be calculated by adopting the following formula:

wherein M represents the weight of the target fruits and vegetables, C represents the required energy in the target fruits and vegetables, and beta represents the energy component in the target fruits and vegetables.

And S204, based on a water quantity calculation formula, determining the required water quantity according to the weight of the target fruits and vegetables, the fruit and vegetable juice yield and the fruit and vegetable juice concentration, and controlling the water outlet of the juicer according to the required water quantity.

The required water amount refers to the weight of clear water required to be added into the fruit juice machine for juicing the target fruits and vegetables according to the concentration of the fruit and vegetable juice. The formula for calculating the water amount can be as follows:

wherein H represents the required water quantity, Y represents the concentration of the fruit and vegetable juice, M represents the weight of the target fruit and vegetable,the juice yield of fruits and vegetables is shown.

After calculating the weight of the clear water to be added into the juicer, the required water amount is sent to the user. Specifically, the water can be displayed to the user through a display screen on the juicer, and the connection between the juicer and other intelligent terminals can also be utilized, for example, the water is sent to the user through a mobile phone, and after the user pours the required water amount into the juicer, the water outlet of the juicer is controlled.

In addition, in some embodiments, a camera can be further arranged on the fruit and vegetable recommendation-based juicer control method, so that a relevant image of a container placed below a water outlet of the juicer is shot through the camera, the collected image is analyzed, the juicer is controlled to automatically stop water outlet, and the juicer stops when being full.

Specifically, the fruit and vegetable recommendation-based juicer control method can comprise the following steps: acquiring a container image of a container placed below a water outlet of a juicer, the container image including a port profile image of the container port and a water volume change image within the container; judging whether the water quantity in the container reaches a water level threshold value or not according to the port outline image and the water quantity change image; and if the water quantity in the container reaches the water level threshold value, controlling the juicer to stop discharging water.

The type of the container can be flexibly set according to actual needs, and the container is a water cup such as a plastic cup, a ceramic cup, a glass cup or a vacuum cup. The port profile may be an upper port edge of the container for ingress and egress of water (e.g., a cup edge).

When the water level threshold is determined, the specific steps may be: acquiring the diameter of the port outline; determining a diameter interval in which the diameter is positioned to obtain a target diameter interval; and determining the water level threshold corresponding to the target diameter interval according to the mapping relation between the different diameter intervals and the different water level thresholds.

After the port profile of the container is obtained, the mapping relation between the preset different diameter intervals and different water level thresholds can be obtained, the diameter size of the port profile of the container is obtained, and then the diameter interval where the diameter size is located is determined, so that the target diameter interval is obtained. At this time, the water level threshold corresponding to the target diameter section may be determined according to the mapping relationship between the different diameter sections and the different water level thresholds.

The water in the container can form an adhesion effect on the inner wall of the container due to the existence of tension, so that the water optically shows optical characteristics such as abnormal refraction effect, and the optical characteristics can be captured and identified through a camera in the view of visual identification technology. Therefore, during the process of water outlet of the juicer, after the current image containing the container is acquired, the water surface boundary generated based on the tension formed between the container and the water can be extracted from the current image. That is, the water level in the container fluctuates due to tension in the water discharging process of the juicer, and an obvious reflective boundary is arranged at the boundary of the inner wall of the container, so that the boundary of the water level can be obtained through image analysis.

And comparing the water level threshold with the water surface boundary, and judging whether the size difference between the water level threshold and the water surface boundary is smaller than a preset threshold, wherein the preset threshold can be flexibly set according to actual needs. The lower the water level is because the less the water quantity in the container is, the smaller the water surface boundary extracted from the current image is; the more the water quantity in the container is, the higher the water level is, the larger the water surface boundary extracted from the current image is, therefore, when the difference between the water level threshold and the water surface boundary is greater than or equal to the preset threshold, the water quantity in the container is less, and the water outlet state of the juicer can be maintained at the moment. When the difference between the water level threshold and the water surface boundary is smaller than the preset threshold or equal to the preset threshold, the water amount in the container is large, the water surface boundary is matched with the water level threshold, namely the distance between the water level and the port of the container is determined, and the juicer can be controlled to stop water discharging. Not only realized automatic control juice extractor and gone out water, can effectively reduce accident such as scald because of the hot water spills over and cause moreover, promote the security.

According to the fruit and vegetable recommendation-based fruit and vegetable juice control method disclosed by the embodiment, the body information sent by the body fat scale is received, so that the target fruit and vegetable is determined according to the body information, and then the required water amount is calculated according to the weight of the target fruit and vegetable, the fruit and vegetable juice yield and the fruit and vegetable juice concentration, so that the obtained fruit and vegetable juice is appropriate in concentration. In addition, the weight of the needed target fruits and vegetables is calculated according to the energy consumed in the movement process of the user, so that the fruits and vegetables can be timely supplemented after the user moves, and the nutrition balance of the user is guaranteed.
