[0048] A cleaning method for a blender self-cleaning device includes a blender self-cleaning system, the blender self-cleaning system including a cleaning module and an adjustment module, the cleaning module including a telescopic control submodule, a liquid transmission submodule, and a valve control submodule, the telescopic control submodule being electrically connected to a linear drive, the liquid transmission submodule being electrically connected to a first pump body 25 and a second pump body 21, and the valve control submodule being electrically connected to a first valve 23 and a second valve 18;

[0050] The adjustment module includes a logic judgment submodule, a speed control submodule, a liquid level height receiving submodule and a comparison submodule. The speed control submodule is electrically connected to the reducer 3, and the liquid level height receiving submodule is electrically connected to the liquid level sensor 26.

[0051] The mixer self-cleaning system includes the following specific operating steps:

[0052] Step 1: When the mixer needs to be cleaned, first discharge the material in the shell 1, start the cleaning component, and let the external liquid flow into the cleaning rod 8 to clean the shell 1;

[0053] Specifically, the first pump body 25 and the second pump body 21 are started simultaneously to transport the cleaning agent and the liquid into the infusion tank 22, so that the two form a mixed liquid. The nozzle 15 is turned on to spray the mixed liquid onto the inner wall surface of the shell 1. The reducer 3 is started to drive the rotating rod 6 to rotate, thereby driving the nozzle 15 to rotate so that the inner wall of the shell 1 can be sprayed with the mixed liquid, which facilitates the softening and falling of impurities on the inner wall of the shell 1. After the mixed liquid is sprayed and contacted, the linear drive is started through the telescopic control submodule, so that the scraper 14 on the cleaning rod 8 contacts the inner wall of the shell 1, while the rotating rod 6 continues to rotate, so that the scraper 14 can scrape off the fallen impurities.

[0054] After using the mixed liquid, in order to ensure that the inner wall of the shell 1 is clean, the second pump body 21 is closed and the first pump body 25 is started to pump the liquid in the water source to the cleaning rod 8, and then spray it to the inner wall of the shell 1 through the nozzle 15 to brush off the impurities on the inner wall of the shell 1 to ensure that the inner wall of the shell 1 is clean;

[0055] Through the above steps, the cleaning agent and the liquid can be sprayed on the inner wall of the shell 1 in sequence to effectively scrape off the impurities.

[0056] Step 2: After the first cleaning is completed, the second valve 18 is closed, and the liquid and cleaning agent flow into the bottom of the housing 1 to form a mixed liquid. The liquid level sensor 26 detects the height of the mixed liquid inside the housing 1 and determines the amount of impurities scraped off the inner wall of the housing 1;

[0057] It should be noted that this step is performed after the impurities on the inner wall of the housing 1 are cleaned and the delivery of the liquid and the cleaning agent is turned off.

[0058] Step 3: After the first cleaning is completed, the distance recognition unit identifies the extended length of the support rod 12 and compares it with the radius of the housing 1 to determine the degree of impurity adhesion on the inner wall of the housing 1, thereby adjusting the state of the cleaning component to improve the cleaning quality;

[0059] Step 2 includes the following steps:

[0060] Step 2-a: When the cleaning agent and liquid are transferred into the housing 1, the amount of the mixed liquid formed by the cleaning agent and liquid entering the housing 1 is monitored by the metering unit;

[0061] Specifically, the metering unit records the amount of cleaning fluid entering the housing 1 as , the amount of liquid entering the shell 1 is The total amount of the mixed liquid is calculated as follows: ,in is the total amount of the mixed liquid.

[0062] It should be noted that the unit of liquid amount is volume;

[0063] Step 2-b: The liquid level sensor 26 monitors the height of the bottom of the housing 1 and analyzes the actual volume of the mixed liquid. Then, the comparison submodule combines the total amount of the mixed liquid to calculate the amount of impurities scraped off the inner wall of the housing 1;

[0064] Specifically, the calculation formula for the actual volume of the mixed solution is: ,in, is the actual volume of the mixture, is the actual height of the mixed liquid, S is the area of ​​the bottom of the shell 1;

[0065] The calculation formula for the amount of impurities scraped off the inner wall of the shell 1 is: ,in is the ratio of the volume of impurities scraped off the inner wall of the shell 1 to the actual volume of the mixed liquid. When the scraped impurities are small, it means the quality is low. When , it means that the amount of impurities scraped off is large and it is of high quality.

[0066] Step three includes the following steps:

[0067] Step 3-a: In the logic judgment submodule, the radius of the shell 1 is set to L, and the distance between the side of the scraper 14 close to the inner wall of the shell 1 and the rotating rod 6 monitored in real time by the distance recognition unit is , compare the two to determine whether the impurities on the inner wall of the shell 1 are cleaned;

[0068] Specifically, when L is equal to When the impurities on the inner wall of the shell 1 are cleaned, When it is less than L, it indicates that the impurities on the inner wall of the shell 1 are not cleaned up, and the degree of impurities adhering to the inner wall of the shell 1 is judged;

[0069] To further determine the degree of impurity adhesion, the calculation formula is: ,in, is the ratio of the thickness of impurities attached to the inner wall of the shell 1 to the radius of the shell 1. When the thickness of impurities attached to the inner wall of the shell 1 is low, When , it indicates that the thickness of impurities attached to the inner wall of the shell 1 is high.

[0070] Step 3-b: Combine the degree of cleanliness of the impurities on the inner wall of the shell 1 with the amount of impurities scraped off to analyze the firmness of the impurities adhering to the inner wall of the shell 1;

[0071] Specifically, when the amount of impurities attached to the inner wall of the shell 1 is low and the amount of impurities scraped off is high, it indicates that the degree of firm attachment of impurities to the inner wall of the shell 1 is low, indicating that the impurities on the inner wall of the shell 1 are easily scraped off;

[0072] When the impurities attached to the inner wall of the shell 1 are of low grade and the amount of impurities scraped off is low, or when the impurities attached to the inner wall of the shell 1 are of high grade and the amount of impurities scraped off is high, it means that the impurities on the inner wall of the shell 1 are firmly attached to the inner wall of the shell 1 and can only be partially scraped off;

[0073] When the impurities attached to the inner wall of the shell 1 are of high quality and the amount of impurities scraped off is of low quality, it means that the impurities attached to the inner wall of the shell 1 are of high quality and difficult to scrape off;

[0074] Step 3-c: Adjust the state of the cleaning component according to the condition of impurities attached to the inner wall of the housing 1 to improve the quality of cleaning impurities;

[0075] Specifically, when the degree of attachment of impurities to the inner wall of the shell 1 is medium, the cleaning step of step one is repeated. The difference from step one is that the second pump body 21 is first turned on, and the cleaning agent is sprayed onto the inner wall of the shell 1 through the nozzle 15, and it is left to stand for a period of time to give more reaction time, so that the impurities that are difficult to scrape off can be automatically separated better. After a period of time, the scraper 14 is continued to be controlled to contact the inner wall of the shell 1, and the support rod 12 is continued to be slowly extended through the telescopic control submodule to increase the contact pressure of the scraper 14 with the inner wall of the shell 1, thereby improving the efficiency of scraping off impurities, and when the support rod 12 is extended, the distance unit is continued to be identified to be equal to L. or When , it indicates that the processing is successful;

[0076] When the degree of attachment of impurities to the inner wall of the housing 1 is high, the above cleaning method is repeated. The difference from the above method is that after the cleaning agent is left to stand for a period of time, a signal is transmitted to the telescopic control submodule to control the extension of the support rod 12. (based on On the basis of the above, the distance of half the thickness of the impurities is extended), and layered processing is performed to avoid impurities with high firmness at one time. The nozzle 15 is continuously controlled to work while the scraper 14 is running, and the cleaning agent is sprayed while scraping the impurities. The speed of the reducer 3 is controlled to reduce the rotation speed through the rotation control submodule, thereby driving the rotation speed of the rotating rod 6 to reduce the working speed of the scraper 14, so that the impurities can be fully scraped off, and the "knife letting" phenomenon caused by too high a speed can be avoided.

[0077] After this layer is scraped off, the support rod 12 is controlled to continue to extend. During the extension process, the impurities on the inner wall of the shell 1 are continuously scraped off until the scraper 14 contacts the inner wall of the shell 1, and the remaining impurities can be scraped off. After scraping off the impurities in this mode, if the impurities are still not scraped off cleanly, it means that there is a "knife let-up" phenomenon, which means that there is a problem in the cleaning component. The work needs to be suspended for the staff to inspect or replace the cleaning component to ensure the working efficiency of the cleaning component.

[0078] It should be noted that, since the scraper 14 sprays the cleaning agent while working and the speed of the scraper 14 is reduced, the reaction time between the cleaning agent and the impurities can be further increased, and the impurities can be scraped off better.

[0079] It should be noted that, in this document, relational terms such as first and second, etc., are used only to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the terms "comprises," "comprising," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that includes a list of elements includes not only those elements but also other elements not explicitly listed, or elements inherent to such process, method, article, or apparatus.

[0080] Finally, it should be noted that the above descriptions are merely preferred embodiments of the present invention and are not intended to limit the present invention.
