Description

Technical Field

[0001] The invention relates to the technical field of cleaning, and in particular to an easy-to-clean medicine decocting pot and an automatic cleaning method. Background Art

[0002] A decoction pot is a container specially used for decocting Chinese medicine. It is usually made of high temperature resistant materials. Its main purpose is to decoct Chinese medicine with water so that the active ingredients of the medicine are dissolved in the water for subsequent use. Cleaning the decoction pot is crucial to ensure the safety and efficacy of Chinese medicine decoction, mainly because the residues and impurities left on the decoction pot may affect the next decoction of the medicine, causing cross contamination, which in turn affects the efficacy of the medicine, and may cause the active ingredients in the medicine to react with the residues, changing the properties of the medicine and reducing its efficacy.

[0003] In order to save the time and effort required for manual cleaning, the decoction pot can now be automatically cleaned. This technology allows users to start the automatic cleaning process by simply pressing a button after each decoction. First, the device automatically adds water and rotates the container to ensure that the residue and impurities inside are thoroughly rinsed. After a set fixed time, the system automatically discharges the waste water to complete the cleaning process. This design not only greatly simplifies the cleaning steps, but also improves the convenience of use, allowing users to focus more on the decoction process without having to worry about the trouble of cleaning.

[0004] However, manual control may lead to the problem of untimely cleaning due to negligence, and the dirt will be more difficult to remove. Moreover, if only water is used for cleaning, there will be some residual medicine stains that are difficult to effectively dissolve, as well as stubborn dirt and sediments that are difficult to physically remove. However, if excessive detergent is selected or the cleaning time is longer only for the sake of cleaning strength, the decoction pot will be over-cleaned and cause losses.

[0050] In order to further explain the technical means and effects adopted by the present invention to achieve the predetermined invention purpose, the following is a detailed description of the specific implementation, structure, features and effects of a decoction pot and an automatic cleaning method that are easy to clean according to the present invention in combination with the accompanying drawings and preferred embodiments. In the following description, different "one embodiment" or "another embodiment" does not necessarily refer to the same embodiment. In addition, the specific features, structures or characteristics in one or more embodiments can be combined in any suitable form.

[0051] Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs.

[0052] The specific scheme of an easy-to-clean medicine decocting pot and an automatic cleaning method provided by the present invention is described in detail below with reference to the accompanying drawings.

[0053] The present invention provides a decoction pot that is easy to clean, comprising a decoction pot body and a cleaning control module, wherein the cleaning control module is used to analyze the cleaning requirements of the decoction pot and perform automatic cleaning, the cleaning control module comprises a collector, a cleaning component and a controller, wherein the collector is connected to the controller, the controller is used for data processing and machine control, the chip type is FPGA, receives data information from the collector, and controls the cleaning component.

[0054] The medicine decoction pot body includes a medicine decoction container, a pressure sensor, a detergent bin, a water pipe, a valve and a cleaning component. Figure 2 , which shows a schematic structural diagram of a decoction pot that is easy to clean provided by an embodiment of the present invention when not in operation, Figure 3 , which shows a schematic diagram of the structure of a decoction pot that is easy to clean provided by an embodiment of the present invention during cleaning work, wherein A represents a cleaning component, B represents a detergent bin, C represents a water pipe, D represents a pressure sensor, and R represents a valve. The decoction container is set to be cylindrical, a pressure sensor is placed at the bottom, and two valves are on the side of the decoction pot, one for the detergent to enter and the other for the water to enter. The decoction pot can be set to decoct medicine at three gears: low heat, medium heat, and high heat. A cleaning component is installed on the outside of the decoction container. In this embodiment, the cleaning component is two automatically retractable brushes, one for cleaning the side wall and the other for cleaning the bottom.

[0055] See also Figure 1 , which shows a flow chart of an automatic cleaning method for an easy-to-clean medicine decoction pot provided by an embodiment of the present invention, the method comprising the following steps:

[0056] S1: After the decoction pot is started, the pressure data and the fire power data at each sampling moment are obtained; according to the mutation degree of the local pressure data at each sampling moment, and the size distribution of the pressure data and the fire power data, the initial cleaning moment is determined.

[0057] Pour the prepared Chinese medicinal materials evenly into the decoction pot, ensure that the amount and type of the medicinal materials meet the prescription requirements, and then turn on the power. After turning on the power, obtain the pressure data and fire power data at each sampling moment. In the embodiment of the present invention, the data is collected at a sampling frequency of 1 Hz, and the fire power is obtained according to the known power corresponding to the low fire, medium fire and high fire selected in real time for decoction. The specific numerical value can be adjusted by the implementer according to the specific implementation scenario, and there is no limitation here.

[0058] During the decoction process, the firepower required at different times can be adjusted according to the characteristics of the medicinal materials and the needs of decoction until the decoction is completed. After the decoction is completed, the decoction pot must be cleaned after the liquid medicine and residue are poured out. Pouring out the liquid medicine and residue will cause the weight of the decoction pot to drop suddenly, and the pressure data will show obvious mutations. However, considering that adding water during the decoction process will also cause obvious changes in the pressure data, or pouring out only part of the liquid at a time will also cause pressure changes, but cleaning cannot be started at this time. Therefore, it is necessary to combine the pressure data and the numerical size of the fire power data to determine the time when cleaning can be done.

[0059] Preferably, in some possible implementations of the present invention, the method for determining the initial cleaning time is described in Figure 4, which shows a flow chart of a method for determining an initial cleaning time provided by an embodiment of the present invention, the method comprising the following steps:

[0060] S101: When the fire power data is zero, for any sampling moment, the pressure data within a preset range before the sampling moment in time sequence is used as the preceding pressure data of the sampling moment; the pressure mutation degree of the sampling moment is obtained according to the mutation degree of the pressure data in all the preceding pressure data of the sampling moment.

[0061] Do not clean during the decoction process. Therefore, when the fire power is not zero, the cleaning situation is not considered. Only when the fire power is zero, it means that the decoction process stops. There may be a cleaning stage after the decoction is completed. At this time, the possible degree of pressure mutation is determined according to the change of pressure data.

[0062] In an embodiment of the present invention, a method for obtaining a sudden change in pressure includes:

[0063] First, all the preceding pressure data at the sampling moment are divided into two categories by the maximum inter-class variance method. Through the classification of the values, one of the two categories is obtained, one is a category with larger pressure data and the other is a category with smaller pressure data. The degree of difference in the overall distribution reflects the magnitude of the change.

[0064] Furthermore, the mean of all preceding pressure data in each category is calculated to obtain the pressure value distribution of each category. The difference in the pressure value distribution between the two categories is calculated to obtain the pressure difference at the sampling moment. The difference between the numerical means of the two categories reflects the overall numerical deviation of the category.

[0065] Finally, the product of the range of all previous pressure data at the sampling moment and the pressure difference is taken as the pressure mutation degree at the sampling moment. The range reflects the maximum possible degree of change in the previous pressure data. The overall deviation is combined to avoid the influence of possible error data on mutation judgment, and the pressure mutation degree is obtained. The greater the pressure mutation degree, the more likely it is that a great degree of pressure data change has occurred before the sampling moment, and the more likely it is that cleaning can be started.

[0066] In a specific implementation method of the present invention, the preset range is set to 15 sampling time ranges, and the specific numerical values ​​can be adjusted by the implementer. It should be noted that the maximum between-class variance method is a technical means well known to those skilled in the art and will not be described in detail here.

[0067] S102: The pressure data at the first sampling moment after the decoction pot is started is used as the starting pressure data; the pressure distribution degree at the sampling moment is obtained according to the deviation degree between the values ​​of the pressure data at the sampling moment and the previous preset number of pressure data and the starting pressure data.

[0068] Taking into account that when only part of the liquid is poured out, there will be a sudden change in the data, and cleaning cannot be performed, the greater the change in the pressure data and the closer it is to 0, the more likely it is that all the liquid and residue have been poured out, and the more likely it is that cleaning is needed.

[0069] In an embodiment of the present invention, a method for obtaining the pressure distribution degree includes:

[0070] First, the mean of the values ​​of the pressure data at the sampling moment and before a preset number of times is calculated as the distribution value at the sampling moment, and the value of the local pressure data before the sampling moment reflects the value size of the stable pressure data.

[0071] Then, the difference between the distribution value at the sampling moment and the initial pressure data is calculated as the pressure difference at the sampling moment. The initial pressure data is reflected in the pressure data when the decoction pot is full when the decoction begins. The greater the pressure difference, the more medicine liquid and residue are poured out of the pot.

[0072] Finally, the ratio of the pressure difference at the sampling moment to the initial pressure data is taken as the pressure distribution degree at the sampling moment. The larger the pressure distribution degree, the closer the pressure difference is to the initial pressure data, and the smaller the distribution value at the sampling moment, the more likely it is that the medicine liquid and residue have been poured out.

[0073] In a specific implementation method of an embodiment of the present invention, the preset number is set to 5, and the implementer can adjust it according to the specific implementation situation.

[0074] S103: Combine the pressure mutation degree and pressure distribution degree at the sampling moment to obtain the cleaning possibility at the sampling moment; traverse in chronological order to obtain the cleaning possibility at the sampling moment when the fire power data is zero, and when there is a cleaning possibility greater than a preset cleaning threshold, the corresponding sampling moment is used as the initial cleaning moment.

[0075] The degree of cleaning that can be performed is comprehensively determined by combining the degree of mutation and the pressure distribution, and after the fire stops, the analysis and judgment are performed in time sequence, and the initial cleaning time is obtained when there is a very high possibility of cleaning. In the embodiment of the present invention, the product of the pressure mutation degree and the pressure distribution degree at the sampling moment is normalized as the cleaning possibility at the sampling moment. When the pressure mutation degree and the pressure distribution degree are larger, it means that the pressure has a mutation, and the pressure value is low at this time, and the possibility of cleaning is greater.

[0076] In a specific implementation of an embodiment of the present invention, the preset cleaning threshold is set to 0.9, and the specific value can be adjusted by the implementer. It should be noted that normalization is a technical means well known to those skilled in the art, and the normalization can be linear normalization or standard normalization, etc. The specific normalization method is not limited here.

[0077] S2: The dirt presence degree of the medicine decocting pot is obtained through the operation time and pressure change before the initial cleaning time; the cleaning requirement of the medicine decocting pot is obtained according to the change distribution of the fire power data before the initial cleaning time and the dirt presence degree of the medicine decocting pot.

[0078] During the decoction process, the effective ingredients in the medicinal materials will be continuously released into the medicinal liquid. As the decoction time increases, various components in the medicinal materials, including plant fiber, pigments, starch and other impurities, will gradually settle on the bottom or wall of the pot, forming dirt.

[0079] And due to long-term heating, the oil and other substances in the medicinal materials will precipitate, and these substances will solidify on the pot wall after cooling, forming stubborn dirt. For medicinal materials of different qualities, generally speaking, the greater the relative mass of the medicinal materials, the more precipitated substances there are, and the higher the degree of dirt. Therefore, the duration and pressure level can reflect the presence of dirt in the decoction pot.

[0080] Preferably, in some possible implementations of the embodiments of the present invention, the method for obtaining the degree of dirt presence includes:

[0081] First, the product of the range of all pressure data before the initial cleaning moment and the minimum value of the pressure data is normalized to obtain the quality index. Since the initial cleaning moment includes the moment after the liquid medicine residue has been poured out, the degree of medicinal material quality is reflected by the range. The larger the range, the greater the quality of the added medicinal material. The minimum value of the pressure data is reflected in the size of the pressure data after pouring out. The larger the minimum value, the more possible residual conditions. Therefore, in the analysis of medicinal material quality, the higher the quality index, the greater the cleaning intensity required.

[0082] Secondly, the total number of sampling times before the initial cleaning time is used as a duration indicator. The larger the duration indicator is, the longer the decoction time is, the more stains will accumulate, and the greater the cleaning effort required.

[0083] Finally, the product of the quality index and the time index is normalized to obtain the degree of dirt accumulation in the decoction pot. The quality of the medicinal materials and the decoction time are combined to reflect the degree of dirt accumulation.

[0084] After determining the possible degree of dirt in the decoction pot caused by decocting medicine, considering that the degree of cleaning required for the decoction pot is not only related to the degree of dirt, the more stubborn the dirt is, the higher the degree of cleaning should be. The fire factor is the main reason for the stubbornness of the dirt. The greater the fire, the more serious the charring of the medicinal material surface, the easier it is to adhere to the inside of the container, increasing the difficulty of cleaning. Therefore, the overall distribution of the fire power is further combined with the existence of dirt to obtain the required cleaning intensity.

[0085] Preferably, in some possible implementations of the embodiments of the present invention, the method for obtaining the cleaning requirement degree includes:

[0086] First, the number of sampling moments corresponding to each type of fire power data is obtained before the initial cleaning moment as the duration of each type of fire power data. In the embodiment of the present invention, since the firepower is divided into low fire, medium fire and high fire, the types of fire power data are divided into three types, and the greater the firepower, the higher the power required. The duration of each fire power under different firepower is different, and the duration corresponding to different firepower is reflected by counting the number of sampling moments.

[0087] Then, the product of each fire power data and the corresponding duration is taken as the fire power of each fire power data. The higher the power and the longer the duration, the greater the fire power impact. The sum of the fire power of all fire power data is taken as the fire influence. The influence of all fire powers is combined to obtain the overall influence of the fire on the difficulty of cleaning dirt.

[0088] Finally, the product of the fire influence and the dirt presence is normalized to obtain the cleaning requirement of the decoction pot. The greater the fire influence, the greater the overall firepower of the decoction process, and the more difficult it is to clean the dirt. The greater the dirt presence, the more serious the dirt accumulation, and the more difficult it is to clean the decoction pot.

[0089] S3: Obtain the cleaning dosage of the medicine decocting pot according to the cleaning demand of the medicine decocting pot and the expected maximum cleaning dosage; obtain the washing time of the medicine decocting pot based on the cleaning dosage of the medicine decocting pot and the washing degree of the detergent; automatically clean the medicine decocting pot according to the initial cleaning time, washing time and cleaning dosage.

[0090] Since the purpose of the detergent is to dissolve and clean the dirt, the use of the detergent is also likely to cause chemical erosion problems. The amount of the detergent is adaptively adjusted by the cleaning force to reduce the chemical impact of the detergent on the decoction pot. In an embodiment of the present invention, the expected maximum detergent dosage can be cleaned through 5 groups of experiments, which are pre-decoctioned at the maximum firepower for the longest time under the maximum medicinal material quality. During the decoction pot cleaning process, an appropriate amount of detergent is added until the dirt no longer changes, and then the detergent is added cumulatively until the dirt is completely removed. At this time, the amount of detergent is recorded and combined with all experimental groups to obtain the expected maximum detergent dosage. The expected maximum detergent dosage is also the required detergent dosage for the decoction pot to require 100% of the detergent.

[0091] Preferably, in an embodiment of the present invention, the product of the cleaning requirement of the medicine decocting pot and the expected maximum cleaning dose is used as the cleaning dose of the medicine decocting pot, and the maximum cleaning dose is adjusted according to the cleaning requirement to alleviate the possible harm caused by excessive cleaning dose.

[0092] After determining the required detergent dosage, since different detergents have different cleaning rates, the cleaning degree of the detergent can be obtained by pre-analyzing the cleaning time of the unit detergent. In the embodiment of the present invention, the unit cleaning time of the detergent is obtained as the cleaning degree of the detergent. In the process of analyzing the five groups of experiments with the expected maximum detergent dosage, the embodiment of the present invention records the cleaning period during which the dirt is cleaned and no longer changes after adding a certain amount of detergent. The ratio of the cleaning period to the added detergent dosage is used as the unit cleaning time for a single analysis, and the average of all unit cleaning times during the cleaning process is used as the cleaning degree of the detergent.

[0093] Then, the product of the cleaning amount of the medicine decocting pot and the washing degree of the corresponding cleaning agent is used as the washing time of the medicine decocting pot. The required cleaning time is determined by selecting the washing degree of the cleaning agent combined with the cleaning amount obtained by the demand analysis.

[0094] Finally, a control instruction can be output according to the initial cleaning time, washing time and detergent dosage to automatically clean the medicine decoction pot. In an embodiment of the present invention, after the initial cleaning time, a detergent and water of the obtained detergent dosage are added, and the cleaning component is controlled to perform the cleaning task for a continuous cleaning time equal to the length of the washing time, thereby realizing automatic cleaning of the medicine decoction pot.

[0095] In summary, the present invention determines the time when automatic cleaning can be performed through the change of pressure data in time series and the numerical distribution of pressure and fire data, and adaptively judges the time when cleaning is started after the liquid medicine and residue are poured out according to the gravity change in the medicine decocting pot, so as to ensure the timely cleaning of the medicine decocting pot. Considering that the more medicinal materials for decocting medicine and the longer the decocting time, the more residual dirt will be left, and the greater the firepower, the higher the degree of residual adhesion. By determining the duration and pressure change before the initial cleaning moment, combined with the change of fire power, the cleaning demand of the medicine decocting pot is obtained, reflecting the degree of difficulty in cleaning the existing dirt. Finally, the cleaning amount is adaptively obtained through the cleaning demand, the washing time is analyzed, and the strength of automatic cleaning is guaranteed. The present invention analyzes the pressure and firepower changes of the medicine decocting pot in real time, adaptively judges the cleaning demand, adjusts the time and cleaning amount of automatic cleaning, reduces cleaning damage while ensuring the cleaning strength, and makes automatic cleaning more reliable.
