[0042] It should be understood that the specific embodiments described herein merely serve to explain the present application and do not limit the present application.

[0043] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the accompanying drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application. Based on the embodiments in the present application, all other embodiments obtained by those of ordinary skill in the art without creative work fall within the scope of the present application.

[0044] With reference to Figure 1 A redundant foam recycling method according to an embodiment of the present application comprises the following steps.

[0045] S1, when it is detected that a user's hand appears in a preset range, determining whether the user's hand has cleaning foam;

[0046] S2, if the user's hand has cleaning foam, obtaining parameter information of the cleaning foam;

[0047] S3, determining whether the parameter information meets a preset condition;

[0048] S4, if the parameter information meets the preset condition, performing a recycling operation corresponding to the preset condition on the cleaning foam.

[0049] As described in steps S1 to S4 above, the execution subject in the present solution is a hand washing machine. In the present solution, a recycling suction port, a recycling container cavity and a sensing device are additionally designed on the hand washing machine. When the sensing device senses that the user's hand with foam appears in the range of the recycling suction port, based on the proportion of the foam on the hand, the foam is recycled and stored, and based on reducing the foam contaminated by the palm during recycling, the recycling path is also designed according to the proportion of the foam on the hand.

[0050] In the steps S1-S2, when the induction device senses that the user's hand with the cleaning foam appears in the range of the recycling suction port, the hand image of the user is obtained by camera shooting or pattern scanning, and then it is judged whether the cleaning foam is in the user's hand according to the hand image. The hand image in the object image is identified by image recognition technology, and the relevant parameter information of the cleaning foam in the hand image is obtained, wherein the parameter information includes the area ratio of the cleaning foam in the user's hand, the thickness parameter of the cleaning foam in the user's hand and other information.

[0051] In the above embodiment, before obtaining the parameter information of the cleaning foam, the method further comprises: obtaining a large number of cleaning foam images from big data and storing them in a database to obtain a cleaning foam image database; establishing a cleaning foam recognition model, copying the data in the cleaning foam image database into training data and test data; inputting the training data into the cleaning foam recognition model for training until the training accuracy threshold and the preset training times are reached; inputting the test data into the cleaning foam recognition model which has completed training for testing until the test accuracy threshold and the preset test times are reached. In this embodiment, the size and shape of the cleaning foam on the user's hand are identified by the cleaning foam recognition model to obtain the area ratio, thickness parameter and other parameter information, which facilitates subsequent judgment of whether these parameter information meet the preset conditions and improves the accuracy of executing the recycling operation.

[0052] Further, the parameter information includes the area ratio of the cleaning foam in the user's hand, and the step S3 of judging whether the parameter information meets the preset condition comprises:

[0053] S31, obtain the area ratio of the cleaning foam in the user's hand, and judge whether the area ratio meets the first preset value.

[0054] In the step S31, the hand image in the object image is identified, the size of the hand in the hand image is judged and calculated, the area size of the cleaning foam in the hand image is obtained, and the area ratio of the cleaning foam in the user's hand is calculated in combination with the size of the hand and the area size of the cleaning foam. The first preset value can be 100%, 90% or the like, and the first preset value can be set according to the type of cleaning foam, the concentration of the foam and the cleaning ability of the foam. For example, the area ratio of the cleaning foam with good cleaning effect can be lower, and the area ratio of the cleaning foam with poor cleaning effect needs to be higher.

[0055] Further, with reference to Figure 2 , the step S4 of executing the recycling operation corresponding to the preset condition on the cleaning foam if the parameter information meets the preset condition comprises:

[0056] S41, if the area ratio meets the first preset value, the recycling dose is determined according to the area ratio.

[0057] S42, determining whether the recovered dose is less than or equal to a second preset value;

[0058] S43, if the recovered dose is less than or equal to the second preset value, performing a first recovery operation on the cleaning foam;

[0059] S44, if the recovered dose is greater than the second preset value, performing a second recovery operation on the cleaning foam.

[0060] In the above steps S31-S32, since the proportion of the cleaning foam is in different ranges, if the same fixed-point back-suction operation is performed on the cleaning foam with different proportions, part of the cleaning foam contaminated by the hand may also be recovered, which causes other recovered cleaning foam to be contaminated, affecting the recovery effect. Therefore, when the recovered dose is greater than the second preset value, the recovery suction port is controlled to perform a circular back-suction, so as to reduce the fixed-point back-suction of too much cleaning foam and suck in the contaminated foam of the watch. Similarly, the second preset value can be set according to the type of the cleaning foam, the foam concentration, and the cleaning ability of the foam. When the area proportion of the foam is small, the required recovered dose is also small, and therefore the first recovery operation is to perform a fixed-point back-suction on the cleaning foam, which can improve the efficiency of the user's hand washing and avoid the user waiting for too long, thereby improving the user's experience. When the recovered dose is greater than the second preset value, the second recovery operation is performed on the cleaning foam. The second recovery operation is a circular back-suction, and the length of the circular path is proportional to the recovered dose, which can be half a circle, a whole circle, or a spiral on the outer surface until the estimated recovered dose is completed. In the embodiment, the recovery port is arranged on the recovery pipe, and the recovery pipe is arranged to be movable. For example, the recovery pipe is composed of a horizontal pipe and a vertical pipe connected in communication, and the connection is flexible and deformable. In the case that the user's hand is not moving, the lower middle end of the vertical pipe is driven by a power structure to perform a circular motion, realizing the circular action, and the recovery suction force is generated by a pump or a fan in the washing machine.

[0061] Further, the parameter information includes a thickness parameter of the cleaning foam in the user's hand, and the step S44 of performing the second recovery operation on the cleaning foam when the recovered dose is greater than the second preset value includes:

[0062] S441, if the recovered dose is greater than the second preset value, determining whether the thickness parameter is less than or equal to a third preset value;

[0063] S442, if the thickness parameter is less than or equal to the third preset value, performing a circular back-suction on the cleaning foam of the same surface layer, and the length of the circular back-suction path is proportional to the recovered dose;

[0064] S443, if the thickness parameter is greater than a third preset value, performing the loop back suction of the cleaning foam of the same surface layer, and then performing the loop back suction of the next surface layer, wherein the length of the loop back suction path is proportional to the recycling dose.

[0065] In the steps S441-S443, since the loop back suction of the cleaning foam of the same surface layer is performed, and the recycling dose estimated this time is not sucked back even if a whole loop is completed, it is necessary to determine whether the thickness parameter is less than or equal to the third preset value. Therefore, when the thickness parameter of the cleaning foam is large, the thickness of the foam group is first confirmed, and after the loop back suction of the foam of the same surface layer is performed in the step S442, the height of the recycling suction port is reduced based on the thickness parameter, and the loop back suction is performed again. The height of the recycling suction port is maintained above a preset height. In this embodiment, the thickness parameter can be determined by shooting with a camera or by stereo imaging with a camera.

[0066] Further, after the step S30 of determining whether the parameter information meets the preset condition, the method further comprises:

[0067] S301, if the parameter information does not meet the preset condition, calculating the amount of cleaning foam to be supplemented based on the parameter information;

[0068] S302, discharging the corresponding amount of cleaning foam.

[0069] In the steps S301-S302, specifically, if the area ratio of the cleaning foam in the user's hand does not meet the first preset value, it indicates that the foam in the user's hand does not need to be recycled. Further, it is necessary to determine whether the user's hand can be cleaned by combining the area ratio of the cleaning foam. If the amount of the current cleaning foam cannot meet the user's demand, the user is prompted by voice prompt to move the hand to the cleaning foam outlet, and the cleaning foam is supplemented according to the calculated amount to ensure the cleaning effect.

[0070] Further, after the step S4 of performing the recycling operation on the cleaning foam corresponding to the preset condition if the parameter information meets the preset condition, the method further comprises:

[0071] S5, storing the cleaning foam after the recycling operation to a storage chamber, and converting the cleaning foam into a cleaning liquid for reuse.

[0072] Further, after the step S5 of storing the cleaning foam after the recycling operation to a storage chamber, and converting the cleaning foam into a cleaning liquid for reuse, the method further comprises:

[0073] S6, determining whether the user needs to clean the hand again.

[0074] S7, if the user needs to clean the foam again, the user information is identified, the user database is screened and compared, and it is judged whether the storage chamber stores cleaning liquid corresponding to the user information;

[0075] S8, if the storage chamber stores cleaning liquid corresponding to the user information, the corresponding cleaning liquid is converted into cleaning foam and discharged into the user's hand.

[0076] In the above steps S5-S8, the user information can be identified by face recognition, voice recognition, fingerprint recognition and the like. The user data in the user database is recorded according to whether the user has used the hand washing machine. If the storage chamber stores cleaning liquid corresponding to the user information, and the user needs to clean the hand, the corresponding cleaning liquid is converted into cleaning foam and discharged to the user. Through the above steps, the waste of resources can be effectively avoided, the user can use the cleaning liquid corresponding to himself, and the risk of cross contamination is reduced.
