Description

Technical Field

[0001] The invention belongs to the technical field of Chinese medicine fumigation clothing, and relates to Chinese medicine fumigation clothing equipment and a Chinese medicine fumigation method for clothing. Background Art

[0002] The medicated clothing method is a traditional Chinese medicine method that integrates drugs into clothing (socks, underwear, bras and other underwear), uses body temperature and the volatilization of drugs, and uses the skin to absorb drug ingredients to achieve therapeutic or health-care effects. This method has a long history in my country. Ancient people would soak their underwear in liquid medicine and dry it before wearing it, or make medicine bags on their underwear, wear medicine capsules, or even carry Chinese medicine sachets. Modern technology puts Chinese medicine extracts and health-preserving materials such as far infrared and negative ions into yarn, or applies them to underwear and panties, which plays the role of "taking medicine". The medicated clothing method is a gentle treatment method suitable for chronic diseases and daily health care.

[0003] For example, a Chinese patent document with application publication number CN103127301A discloses a Chinese medicine transdermal absorption drug delivery carrier, a Chinese medicine medicine coat, and a Chinese medicine medicine coat with disease prevention and health care effects. This solution is to put Chinese medicine in the coat, and administer the medicine in a transdermal absorption manner to achieve the problem of disease prevention and health care. This Chinese medicine transdermal absorption drug delivery carrier is to put Chinese medicine into the interlayer of clothes, just like cotton is put in a cotton coat, the medicine coat is filled with Chinese medicine, and the cotton coat is filled with cotton. The medicine coat is worn close to the body, just like Chinese medicine is applied to the body. Through the absorption of the skin and the metabolic function of the skin, the effective ingredients of the medicine enter the blood and circulate throughout the body, achieving the purpose of preventing and treating diseases. The medicine coat, as a carrier, can be loaded with Chinese medicines of different dosage forms as needed. However, the method of loading Chinese medicinal materials into the interlayer of clothing has problems such as poor wearing comfort and large dosage.

[0004] For example, a Chinese patent document with application publication number CN101700386A discloses an anti-liver cancer Chinese medicine composition and its medicine coat, which is made of Hedyotis diffusa, Prunella vulgaris, Solanum nigrum, Herba scutellariae, Polygonum cuspidatum, Scutellaria barbata, Tripterygium wilfordii, Curcuma zedoariae, Dioscorea bulbifera, Vaccaria segetalis, Folium sphaerocephalae, Rhizoma chuanxiong, Capillaris ternatae, Rhizoma alismatis, Radix atractylodes, Polyporus, Polyporus, Radix curcumae, Radix curcumae, Radix bupleuri, Rhubarb, Fructus aurantii, Scolopendra subspinipes, Scorpio, Borneolum, Phellodendron chinense, and Folium styracifolium as raw materials. At the same time, a medicine coat made from the composition is also disclosed, which is made by soaking, boiling, soaking, boiling, and drying the raw materials. However, if clothes are soaked in Chinese medicine liquid, boiled, and air-dried before being worn, there is a drying process, and most of the active ingredients of the medicine attached to the clothes are volatilized and lost, resulting in large waste of medicine, pollution of the clothes by colored liquid medicine, and troublesome operation. Summary of the invention

[0005] In view of the problems existing in the prior art, the present invention proposes a Chinese medicine fumigation clothing device and a Chinese medicine fumigation clothing method, aiming to overcome the defect of large drug loss in the existing medicine clothing manufacturing method.

[0006] The present invention is achieved in that:

[0007] A Chinese medicine fumigation equipment is characterized in that it comprises an outer cylinder and an inner cylinder installed in the outer cylinder, the outer cylinder is covered with a cover body, the inner cylinder has a clothing storage area, and a volatilization area is provided between the inner cylinder and the inner wall of the outer cylinder. The Chinese medicine fumigation equipment is provided with a Chinese medicine atomization device to provide atomized Chinese medicine to the volatilization area, and the Chinese medicine fumigation clothes are provided with a heating device to heat the volatilization area.

[0008] The side wall of the inner cylinder is provided with an air vent, and the inner cylinder is rotatably connected to the outer cylinder. The Chinese medicine fumigation equipment is provided with a rotating mechanism to drive the inner cylinder to rotate relative to the outer cylinder.

[0009] The rotating mechanism comprises a driving motor and a transmission rod, and a gear set is arranged between the driving motor and the transmission rod.

[0010] The traditional Chinese medicine atomization device comprises a tube body connected to the volatilization zone, a liquid storage bottle is arranged on the tube body, and a volatilization rod core and an ultrasonic atomization sheet are arranged in the tube body.

[0011] The heating device comprises an air inlet cavity, a heating element arranged at the outlet of the air inlet cavity, and a fan blowing air to the heating element. The inlet and outlet of the air inlet cavity are both provided with temperature sensors.

[0012] The transmission rod has an air guide channel, which is connected to the air inlet chamber through a connecting pipe. The bottom of the transmission rod is rotatably sealed with the connecting pipe. The upper end of the transmission rod extends into the inner tube. The upper end of the transmission rod is provided with a mesh hollow ball.

[0013] The Chinese medicine fumigation device comprises a shell, the outer cylinder is fixed in the shell, one end of the cover is hinged on the shell, and the other end is detachably locked on the shell;

[0014] The liquid storage bottle is affixed with an RFID tag, and the shell is provided with an RFID reader / writer to identify the formula model of the Chinese medicine volatile oil in the liquid storage bottle.

[0015] The method for fumigating clothes with Chinese medicine is characterized by comprising the following steps:

[0016] Rapid fumigation stage: The Chinese medicine atomization device and the heating device work simultaneously. The Chinese medicine atomization device makes the Chinese medicine volatile oil form Chinese medicine mist droplets or Chinese medicine steam to enter the volatilization area and further fumigate the clothes. The Chinese medicine penetrates into the clothes under the action of hot air flow;

[0017] Penetration fumigation stage: turn off the Chinese medicine atomization device, and operate the heating device to allow the Chinese medicine mist droplets or Chinese medicine steam to further penetrate into the clothes.

[0018] The Chinese medicine fumigation method for clothing also includes the following steps after the penetration fumigation stage:

[0019] Intermittent fumigation stage: During the storage of clothes, the clothes are fumigated again through the Chinese medicine atomization device.

[0020] The Chinese medicine fumigation method for clothing also includes the following steps before the rapid fumigation stage:

[0021] Extraction of volatile oil from Chinese medicine: Extract volatile oil from Chinese medicine by distillation or supercritical fluid extraction, and then decolorize the volatile oil by activated carbon adsorption;

[0022] Adjust working parameters: The RFID reader identifies the formula model of the Chinese medicine volatile oil in the storage bottle, inputs the amount of clothing, adjusts the ultrasonic atomization power of the Chinese medicine atomization device according to the viscosity and surface tension of the Chinese medicine volatile oil, adjusts the maximum heating temperature of the heating device according to the composition of the Chinese medicine volatile oil, and adjusts the atomization fumigation time and the wind speed of the heating device according to the amount of clothing;

[0023] Preheating: The heating device is pneumatically preheated until the temperature of the volatilization zone reaches and is maintained at the highest heating temperature;

[0024] After preheating is completed, the inner cylinder is controlled to rotate and enter the rapid fumigation stage;

[0025] The ultrasonic atomization power is P:

[0026] P=kη×σ b ×f 2 ×d 3

[0027] Where η is the liquid viscosity, σ is the liquid surface tension, f is the ultrasonic frequency, d is the atomized droplet diameter, and k and b are constants determined by fitting experimental data;

[0028] At different temperatures, the volatile oil components were analyzed by gas chromatography-mass spectrometry experiments to determine the critical temperature value of the decomposition of the active ingredients, which was used as the setting value of the maximum heating temperature Tmax of the heating device;

[0029] The fan of the heating device keeps working during the whole rapid fumigation stage, and the heating element of the heating device automatically switches on and off according to the actual temperature T of the volatilization zone, that is, when T>Tmax, the heating element stops working, and when T<Tmin, the heating element restarts working;

[0030] During the intermittent fumigation stage, the Chinese medicine atomization device works intermittently, and the heating device does not work, relying on the natural volatility of the Chinese medicine volatile oil to make up for the loss of the Chinese medicine volatile oil on the clothes.

[0031] The present invention has the following beneficial effects:

[0032] (1) Under the premise of ensuring the concentration of effective ingredients of traditional Chinese medicine attached to clothes, reduce drug loss and avoid contamination of clothes by traditional Chinese medicine stains.

[0033] (2) A three-stage fumigation strategy was proposed by combining ultrasonic atomization fumigation with heated dry fumigation, namely rapid fumigation, penetrating fumigation, and intermittent fumigation, to improve the adhesion concentration, adhesion uniformity, and residence time of the effective ingredients of traditional Chinese medicine on clothing, while ensuring the dryness of the clothing.

[0034] (3) The outer cylinder of the equipment forms a closed cavity structure, which has both the function of fumigating clothes and the function of storing clothes. A strategy for maintaining the effective ingredients of traditional Chinese medicine during storage is designed to solve the problem of volatilization and loss of effective ingredients of traditional Chinese medicine during the storage period.

[0040] The following will further describe the specific implementation of the present invention in combination with the accompanying drawings to make the technical solution of the present invention easier to understand and grasp. It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0041] This embodiment provides a Chinese medicine fumigation device and a Chinese medicine fumigation method for clothes. Figure 1 , 2As shown, the Chinese medicine fumigation equipment includes an outer cylinder 2 and an inner cylinder 1 installed in the outer cylinder 2, the outer cylinder 2 is covered with a cover body 51, the inner cylinder 1 has a clothing storage area, and a volatilization area 21 is provided between the inner walls of the inner cylinder 1 and the outer cylinder 2. The Chinese medicine fumigation equipment is provided with a Chinese medicine atomization device to provide atomized Chinese medicine to the volatilization area 21, and the Chinese medicine fumigation is provided with a heating device to heat the volatilization area 21.

[0042] The Chinese medicine fumigation equipment is equipped with a Chinese medicine atomization device, which converts Chinese medicine into tiny droplets and releases them into the volatilization zone 21. Compared with the traditional method of directly loading Chinese medicinal materials into the interlayer of clothing 7 or soaking, boiling and drying clothing 7, atomization can greatly increase the surface area of ​​the medicine, making it easier for drug molecules to disperse in the air. In the atomized state, the volatilization speed of the drug is significantly improved, and it can quickly enter the clothing storage area and adhere to the clothing 7. The heating device heats the volatilization zone 21. According to the principle of molecular thermal motion, the increase in temperature will intensify the movement of drug molecules. This not only further promotes the volatilization of the drug, but also makes the drug molecules more active and easier to penetrate and adhere to the fibers of clothing 7. The clothing storage area of ​​the inner drum 1 is used to place the clothing 7 to be fumigated. The atomized and heat-active drug molecules in the volatilization zone 21 will gradually diffuse to the clothing storage area under the action of air flow and be adsorbed by the fibers of clothing 7. Since the fibers of clothing 7 have a certain surface area and adsorption properties, they can effectively intercept drug molecules, thereby achieving the combination of drugs and clothing 7, completing a process similar to the traditional drug coating method of integrating drugs into clothing 7, but more efficiently and accurately.

[0043] Through the Chinese medicine atomization device, the amount of Chinese medicine atomization can be accurately controlled, and then the dosage of medicine attached to the clothing 7 can be accurately controlled. Compared with the traditional method of loading Chinese medicine into the interlayer of clothing 7, it avoids the problem of large dosage of medicine, ensures that the content of medicine on the clothing 7 is appropriate each time it is smoked, and guarantees the treatment or health care effect and avoids medicine waste. Different from the discomfort caused by loading Chinese medicine into the interlayer of clothing 7, the medicine clothing made by the Chinese medicine fumigation equipment has medicines evenly attached to the fibers of clothing 7, and there will be no blocky or granular Chinese medicines, making the clothing 7 softer, more comfortable and fit the human body when worn, which improves the user's wearing experience and is conducive to improving the user's acceptance and compliance with medicine clothing therapy. In the traditional method, most of the active ingredients of the medicine attached to the clothing 7 evaporate and lose during the drying process, while the Chinese medicine fumigation equipment can effectively attach more drug molecules to the clothing 7 by accurately controlling the amount of medicine atomization and heating to assist volatilization, and slowly release them during subsequent use. After testing, the drug utilization rate of the drug coat made by this equipment is greatly improved compared with the traditional soaking and drying method, which reduces drug waste and reduces the cost of use. At the same time, the therapeutic or health-care effect of the drug can be more stably exerted. At the same time, for the production of drug coats with different needs, the types and dosage ratios of traditional Chinese medicine can be flexibly adjusted to meet personalized needs. The entire fumigation process does not require the cumbersome procedures of soaking, decocting, and drying the clothes 7. Just place the clothes 7 in the clothing storage area, turn on the traditional Chinese medicine atomization device and the heating device, and the production of the drug coat can be completed in a relatively short time. It greatly simplifies the traditional drug coat production process, solves the problem of cumbersome operation in the traditional method, improves the efficiency of drug coat production, and facilitates users to make drug coats that meet their needs at any time.

[0044] like Figure 1 , 2As shown, the side wall of the inner cylinder 1 is provided with a vent 17, the upper end of the inner cylinder 1 is open, the inner cylinder 1 is rotatably connected to the outer cylinder 2, and the Chinese medicine fumigation clothing device is provided with a rotating mechanism to drive the inner cylinder 1 to rotate relative to the outer cylinder 2. The inner cylinder 1 is rotatably connected to the outer cylinder 2. When the rotating mechanism drives the inner cylinder 1 to rotate relative to the outer cylinder 2, the clothes 7 placed in the clothing storage area of ​​the inner cylinder 1 also rotate accordingly. The atomized and heated drug molecules in the volatilization area 21 continue to diffuse to the clothing storage area, and the rotation of the clothes 7 allows different parts to fully contact the drug molecules in turn. Compared with the static state, the rotation can avoid the situation where the local drug of the clothes 7 is too much or too little attached, and the combined effect of centrifugal force and air flow is used to make the drug molecules more evenly distributed and attached to the fiber surface of the clothes 7, ensuring the uniformity of the combination of the drug and the clothes 7. The vent 17 is set on the side wall of the inner cylinder 1, and during the rotation process, the clothes 7 are in contact with the air more frequently and fully. On the one hand, the rotation causes the gaps between the fibers of the clothing 7 to change continuously, which helps the drug molecules to enter the interior of the fibers and enhance the adsorption effect; on the other hand, the air vents 17 ensure the circulation of air inside and outside, continuously introduces the air rich in drug molecules in the volatilization zone 21 into the inner drum 1, and at the same time discharges the relatively low-concentration drug air in the inner drum 1, forming a dynamic air exchange, accelerating the adsorption speed of drug molecules on the fibers of the clothing 7, and shortening the time for making the drug coat. In other optional embodiments, the side wall of the inner drum 1 can also be in a closed state, the upper end of the inner drum 1 is open, and a vent is set at the lower end, or only the vent is set on the side wall.

[0045] The inner cylinder 1 of this embodiment is formed by a plurality of cylindrical strips arranged circumferentially and spaced apart to form a side wall, and the space between the cylindrical strips is a vent. In other optional embodiments, the side wall of the inner cylinder 1 can also be a plate-like structure, and holes are punched on the plate-like structure to form vents.

[0046] like Figure 1 , 2As shown, the rotating mechanism includes a driving motor 12 and a transmission rod 14, and a gear set 11 is arranged between the driving motor 12 and the transmission rod 14. The driving motor 12 is used as the power source of the rotating mechanism. After being energized, the electric energy is converted into mechanical energy to generate a rotational motion. The output shaft of the motor is connected to the driving gear in the gear set 11, and the rotational power of the motor is transmitted to the output gear through the meshing transmission between the gears. The gear set 11 adjusts the motor speed and torque according to different gear ratios. For example, when a larger torque is required to drive the inner cylinder 1 to rotate, the gear ratio of the gear set 11 can be designed so that the driven gear obtains a larger torque output than the driving gear. Finally, the output gear of the gear set 11 is connected to the transmission rod 14, and the adjusted power is transmitted to the transmission rod 14. The transmission rod 14 is fixedly connected to the inner cylinder 1, driving the inner cylinder 1 to achieve stable rotation, ensuring that the inner cylinder 1 can operate according to the set speed and torque requirements, and providing a power basis for uniform distribution and accelerated adsorption of drugs. In other optional embodiments, the output shaft of the driving motor 12 may also be directly connected to the inner cylinder 1. In other optional embodiments, the inner cylinder 1 may also be driven by wind power.

[0047] like Figure 1 As shown, the Chinese medicine atomization device includes a tube body 41 connected to the volatilization zone 21, a liquid storage bottle 4 is provided on the tube body 41, a volatilization rod core 42 and an ultrasonic atomization sheet 43 are provided in the tube body 41, one end of the volatilization rod core 42 extends into the liquid storage bottle 4, and the other end contacts the ultrasonic atomization sheet 43. The liquid storage bottle 4 stores Chinese medicine volatile oil, and one end of the volatilization rod core 42 directly extends into the liquid storage bottle 4, so that the Chinese medicine volatile oil can be continuously absorbed from the liquid storage bottle 4 to the inside of the rod core. As the Chinese medicine volatile oil in the rod core increases, the Chinese medicine volatile oil moves along the rod core to the other end until it contacts the ultrasonic atomization sheet 43. This design ensures that the Chinese medicine volatile oil can be stably and continuously transmitted from the liquid storage bottle 4 to the ultrasonic atomization sheet 43, providing a stable source of medicine for the subsequent atomization process. A controller is installed on the Chinese medicine fumigation device. The controller has a corresponding driving circuit for controlling the ultrasonic atomizer 43. The ultrasonic atomizer 43 is excited by an electrical signal. When the Chinese medicine volatile oil in the volatilization rod core 42 contacts the ultrasonic atomizer 43, the high-frequency vibration of the ultrasonic atomizer 43 applies huge energy to the Chinese medicine volatile oil, overcomes the surface tension of the liquid, and forms droplets of extremely small particle size. These tiny droplets enter the volatilization area 21, providing a sufficient and highly active source of drugs for the production of medicine clothing.

[0048] The ultrasonic atomizer sheet 43 is composed of multiple sheets, and the tube body 41 has multiple branches, so that multiple sheets of the ultrasonic atomizer sheet 43 can be installed corresponding to different side walls of the outer tube 2, which is beneficial to improve the diffusion rate of the volatile oil of traditional Chinese medicine. In other optional embodiments, the ultrasonic atomizer sheet 43 can also be a single sheet. The surface of the ultrasonic atomizer sheet 43 has a corrosion-resistant layer, such as a Teflon layer, which is suitable for oily liquids. The frequency of the ultrasonic atomizer sheet 43 is 20kHz-2MHz, which produces micron-sized atomized particles. The high-frequency oscillation circuit drives the ultrasonic atomizer sheet 43.

[0049] like Figure 1 As shown, the heating device includes an air inlet chamber 63, a heating element 61 arranged at the outlet of the air inlet chamber 63, and a fan 62 blowing air to the heating element 61. The inlet and outlet of the air inlet chamber 63 are both provided with temperature sensors. The fan 62 sucks in the outside air from the inlet of the air inlet chamber 63 to form a stable airflow. The air inlet chamber 63 guides and preliminarily regulates the airflow, so that the air flows evenly to the heating element 61. After the heating element 61 is powered on, the electrical energy is converted into thermal energy, and its own temperature is rapidly increased. When the air flows through the heating element 61, it absorbs heat through heat conduction and convection, and the temperature of the heated air is significantly increased. The heated air flows out from the outlet of the air inlet chamber 63 and enters the volatilization zone 21, providing a suitable temperature environment for the volatilization of drug molecules, and promoting the drug to diffuse more efficiently in the volatilization zone 21 and adhere to the clothing 7. The temperature sensors at the inlet and outlet of the air inlet chamber 63 respectively monitor the initial air temperature entering the heating device and the temperature of the output air after heating in real time. The temperature sensor transmits the collected temperature data to the controller of the device. The controller intelligently adjusts the power of the heating element 61 and the speed of the fan 62 according to the preset target temperature value. For example, when the temperature sensor at the outlet detects that the output air temperature is lower than the target value, the controller increases the current of the heating element 61 to increase its heating power, and appropriately increases the speed of the fan 62 to speed up the air flow to increase the output air temperature more quickly; conversely, when the temperature is higher than the target value, the power of the heating element 61 and the speed of the fan 62 are reduced to ensure that the air temperature output to the volatilization zone 21 is always stable within the set range. In other optional embodiments, the heating device can also be a heating tube arranged in the volatilization zone 21 surrounding the outer periphery of the inner tube 1.

[0050] The heating element 61 is a PTC heating sheet or a heating wire. In other optional embodiments, the heating element 61 can be as close to the ultrasonic atomization sheet 43 as possible, facing the clothing 7, for example, the interval between the heating element 61 and the ultrasonic atomization sheet 43 is less than 2 cm. The fan 62 adopts a high temperature resistant PWM DC fan 62. The temperature sensor adopts an NTC or thermocouple sensor. The temperature sensor can be controlled by PID or a simple switch to keep the temperature within a set range, such as 30-60°C. The fan 62 adopts PWM control to keep the wind speed within the set range, and automatically cuts off the power when the temperature exceeds the set value (such as 70°C).

[0051] like Figure 1 As shown, the transmission rod 14 has an air guide channel 15, which is connected to the air inlet chamber 63 through a connecting pipe 13. The bottom of the transmission rod 14 is rotatably sealed with the connecting pipe 13. The upper end of the transmission rod 14 extends into the inner tube 1, and a mesh hollow ball 16 is provided on the upper end of the transmission rod 14. Through the cooperation of the fan 62 and the air guide structure of the transmission rod 14, an efficient gas circulation system is constructed. The continuous and stable gas flow can not only quickly update the air in the inner tube 1, but also maintain a stable pressure difference between the volatilization zone 21 and the inner tube 1. This circulation process continuously transports the newly generated drug molecules in the volatilization zone 21 to the surrounding of the clothing 7, and at the same time discharges the relatively low concentration gas that has been attached to the drug molecules in the inner tube 1, creating a good dynamic environment for the continuous penetration and attachment of the drug, and accelerating the process of making the drug coat. The formation of the pressure difference greatly enhances the penetration of the drug molecules. For some clothes 7 with tight texture and fine fibers, it is difficult for drug molecules to penetrate deeply into the interior under the traditional method. Under the pressure difference generated by the structure, the volatile oil vapor or droplets can overcome the resistance of the clothing 7 fibers and penetrate deeper into the clothing 7 fibers to achieve uniform distribution of the drug inside the clothing 7. This enhanced drug penetration function enables the drug coat to release drugs more persistently and stably during use, thereby improving the effect of the drug coat on the treatment and health care of chronic diseases. The mesh design of the hollow ball 16 is not only conducive to gas circulation, but also effectively prevents the clothing 7 from blocking the airway during rotation. Even if the inner cylinder 1 continues to rotate under the drive of the rotating mechanism, the clothing 7 will not hinder the normal circulation of the gas. At the same time, the rotatable sealing connection between the bottom of the transmission rod 14 and the connecting pipe 13 ensures the stability and sealing of the structure during the gas circulation process, avoids the problem of unstable pressure difference caused by gas leakage, and ensures the reliable operation of the entire gas circulation and drug penetration process. The hollow ball 16 is hollowed out in all directions. Even if the upper hollow of the hollow ball 16 is covered by the clothing 7 and partially blocked, the hollow of the lower part of the hollow ball 16 is not easily blocked, ensuring smooth circulation. In other optional embodiments, a hollow portion may be further provided on the side wall of the transmission rod 14 .

[0052] like Figure 1As shown, the Chinese medicine fumigation equipment includes a shell 5, the outer cylinder 2 is fixed in the shell 5, one end of the cover 51 is hinged on the shell 5, and the other end is detachably locked on the shell 5, and a sealing gasket 52 is provided between the cover 51 and the shell 5; the shell 5 serves as the external support frame of the Chinese medicine fumigation equipment, and provides an installation basis for internal core components such as the outer cylinder 2, the inner cylinder 1, the Chinese medicine atomization device, the heating device, etc. The outer cylinder 2 is fixed inside the shell 5 to ensure its stability during the operation of the equipment, and to prevent the position from being offset due to vibration or external force collision, which affects the normal operation of the equipment. The cover 51 is hinged on the shell 5 at one end to form an opening and closing structure similar to a door, which is convenient for the user to open the cover 51, place or take out the clothes 7 in the inner cylinder 1, and perform the medicine clothing making operation. The detachable lock design at the other end tightly fixes the cover 51 to the shell 5 when the cover 51 is closed, forming a relatively closed internal space, creating stable environmental conditions for processes such as gas circulation, drug volatilization and hot air circulation inside the equipment. In other optional embodiments, the cover 51 can also be arranged on the outer tube 2, covering only the upper end of the outer tube 2. The liquid storage bottle 4 is exposed outside the outer shell 5, which is conducive to observing the remaining condition of the volatile oil of traditional Chinese medicine, and the detachable structure is convenient for replacement.

[0053] Furthermore, an RFID tag is attached to the liquid storage bottle 4, and an RFID reader 3 is provided on the housing 5 to identify the formula model of the Chinese medicine volatile oil in the liquid storage bottle 4. The RFID (radio frequency identification) tag is attached to the liquid storage bottle 4, and each tag stores specific information such as the formula model of the Chinese medicine volatile oil in the corresponding liquid storage bottle 4. This information exists in the chip inside the tag in the form of electronic coding. When the liquid storage bottle 4 is placed in the device and close to the RFID reader 3 on the housing 5, the RFID reader 3 will emit a radio frequency signal of a specific frequency. After receiving the signal, the RFID tag generates an electric current using the principle of electromagnetic induction, activates its own chip, and feeds back the stored information to the RFID reader 3 in the form of a modulated radio frequency signal. After receiving the feedback signal, the RFID reader 3 performs demodulation and decoding processing, thereby accurately identifying the formula model of the Chinese medicine volatile oil in the liquid storage bottle 4, and realizing non-contact rapid reading of drug information. After the RFID reader 3 recognizes the tag information, it transmits the data to the controller of the device. The controller compares the received formula model information with various formula parameters pre-stored in the equipment database. These parameters include the optimal atomization amount, heating temperature, inner barrel 1 rotation speed and other key parameters for making medicine coats for different formulas of Chinese medicine volatile oils. Based on the comparison results, the controller automatically adjusts the operating parameters of the Chinese medicine atomization device, heating device, and rotating mechanism and other equipment components to ensure that the equipment can accurately produce medicine coats that meet the requirements according to different Chinese medicine formulas.

[0054] The method of fumigating clothes with Chinese medicine includes the following steps:

[0055] Rapid fumigation stage: The Chinese medicine atomization device and the heating device work at the same time. The Chinese medicine atomization device makes the Chinese medicine volatile oil form Chinese medicine droplets or Chinese medicine steam to enter the volatilization zone 21 and further fumigate to the clothing 7. The Chinese medicine penetrates into the inside of the clothing 7 under the action of the hot air flow. In the rapid fumigation stage, the Chinese medicine atomization device and the heating device are started at the same time. The Chinese medicine atomization device converts the Chinese medicine volatile oil in the liquid storage bottle 4 into tiny Chinese medicine droplets or steam through the internal volatilization rod core 42, ultrasonic atomization sheet 43 and other components. These tiny particles greatly increase the surface area of ​​the medicine, making it more volatile. At the same time, the heating device works, and the fan 62 draws the outside air into the air inlet chamber 63. After being heated by the heating element 61, a hot air flow is formed to enter the volatilization zone 21. The hot air flow not only provides energy for the movement of drug molecules and accelerates their diffusion speed, but also creates a high temperature environment to further promote the volatilization of Chinese medicine volatile oil. Under the synergistic effect of the two, a large amount of Chinese medicine droplets or steam quickly enters the volatilization zone 21, and driven by the hot air flow, quickly fumigates the inner drum 1 where the clothing 7 is located, so that the clothing 7 is exposed to a high concentration of medicine in a short time. The hot air flow carries the Chinese medicine droplets or steam to impact the surface of the clothing 7. Due to the kinetic energy of the hot air flow and the influence of temperature, the fibers of the clothing 7 will expand to a certain extent, and the gaps between the fibers will increase. This creates favorable conditions for the Chinese medicine droplets or steam molecules to penetrate into the interior of the clothing 7. Driven by the hot air flow, some Chinese medicine molecules begin to penetrate from the surface of the clothing 7 to the inside, and initially attach to the fibers of the clothing 7, laying the foundation for subsequent deeper penetration.

[0056] The simultaneous operation of the Chinese medicine atomization device and the heating device can convert a large amount of Chinese medicine volatile oil into a fumigable state in a short time and quickly transport it to the surrounding of the clothing 7. Compared with the operation of a single device, the speed of loading the drug onto the clothing 7 is greatly improved. This can meet emergency needs for some scenarios where medicine clothing needs to be made quickly, such as the production of medicine clothing for emergency use in hospitals, and buy treatment time for patients. The hot air flow assists the volatilization and fumigation of Chinese medicine volatile oils, and for some less volatile Chinese medicine formulas, it can also effectively form droplets or steam and penetrate into the clothing 7. This broadens the range of Chinese medicine types that the equipment can be used for, allowing more types of Chinese medicine to be used to make medicine clothing, enriching the formula selection of medicine clothing.

[0057] The fan 62 of the heating device works continuously during the entire rapid fumigation stage. The heating element 61 of the heating device automatically switches on and off according to the actual temperature T of the volatilization zone 21. The maximum heating temperature of the heating device is Tmax, that is, when T>Tmax, the heating element 61 stops working, and when T<Tmin, the heating element 61 restarts working.

[0058] Infiltration fumigation stage: Turning off the Chinese medicine atomization device can avoid the generation of too many Chinese medicine droplets or Chinese medicine steam and avoid waste. The heating device works to allow the Chinese medicine droplets or Chinese medicine steam to further penetrate into the clothing 7. After turning off the Chinese medicine atomization device, the heating device continues to work to maintain the thermal environment in the volatilization zone 21. At this time, the Chinese medicine droplets or steam already existing in the volatilization zone 21 continue to maintain an active state of motion under the action of the continuous hot air flow. The hot air flow continues to impact the clothing 7, constantly providing power for the Chinese medicine molecules to penetrate into the clothing 7. Over time, under the action of heat, the Chinese medicine molecules further overcome the resistance of the clothing 7 fibers, gradually penetrate deeper into the clothing 7 fibers, and achieve deep penetration of the drug into the clothing 7. During the penetration process, the Chinese medicine molecules continuously search for suitable adsorption sites through molecular diffusion between the clothing 7 fibers. Because the clothing 7 fibers have certain chemical activity and surface characteristics, the Chinese medicine molecules interact with the functional groups on the fiber surface and gradually adsorb on the fibers. This adsorption effect is more stable with the assistance of heat, so that the drug can be firmly attached to the clothing 7, ensuring that the drug can be released continuously and slowly during subsequent use.

[0059] The Chinese medicine fumigation method for clothing also includes the following steps after the penetration fumigation stage:

[0060] Intermittent fumigation stage: During the storage of clothing 7, the clothing 7 is fumigated again by the Chinese medicine atomization device. During the storage of clothing 7, the Chinese medicine atomization device is started for fumigation, and the Chinese medicine atomization device converts the Chinese medicine volatile oil in the liquid storage bottle 4 into tiny droplets or steam again. As time goes by, the medicine on the surface and inside of the medicine coat will gradually decrease due to natural volatilization and other reasons during the storage process. At this time, the newly generated Chinese medicine droplets or steam can attach to the fibers of clothing 7 again to replenish the amount of medicine that has been lost. Since the fibers of clothing 7 have undergone the penetration and adsorption process of the drug in the previous penetration fumigation stage, their fiber structure and surface characteristics have adapted to the drug molecules. Therefore, in the intermittent fumigation stage, the drug molecules are more likely to combine with the fibers of clothing 7, thereby achieving rapid replenishment of the drug.

[0061] Since the medicine volatilizes mainly on the surface of the clothing 7 during the storage of the clothing 7, the heating device may not be started during the intermittent supplementary fumigation stage. During the intermittent supplementary fumigation stage, the Chinese medicine atomization device works intermittently, and the heating device does not work, relying on the natural volatility of the Chinese medicine volatile oil to make up for the loss of the Chinese medicine volatile oil on the clothing 7. In other optional embodiments, during the supplementary fumigation process, the heating device may also be operated appropriately as needed to create a certain thermal environment. The hot air flow helps the Chinese medicine droplets or steam to diffuse better and penetrate into the clothing 7.

[0062] The Chinese medicine fumigation method for clothing also includes the following steps before the rapid fumigation stage:

[0063] Extraction of volatile oil from Chinese herbal medicine: Extract volatile oil from Chinese herbal medicine by distillation or supercritical fluid extraction, and then decolorize the volatile oil by activated carbon adsorption. Taking advantage of the difference in boiling points between volatile oil and other components in Chinese herbal medicine, co-distill Chinese herbal medicine with water, so that volatile oil is distilled out with water vapor, and collected after condensation to separate volatile oil from other impurities. For example, for aromatic Chinese herbal medicine containing volatile oil, the volatile oil is first vaporized when heated, mixed with water vapor and escaped, and the oil and water are separated after cooling to obtain volatile oil. Using a fluid in a supercritical state (temperature and pressure exceeding the critical value) as an extractant, and utilizing its special solubility for solutes, volatile oil is extracted from Chinese herbal medicine. Supercritical fluids such as carbon dioxide have the low viscosity and high diffusivity of gas and the high density and good solubility of liquid in a supercritical state, and can efficiently extract volatile oil from medicinal materials. When the pressure and temperature change, the solubility of the supercritical fluid changes, thereby achieving the separation of volatile oil and extractant. Activated carbon has a highly developed pore structure and a huge specific surface area, and there are many active sites on its surface. Impurity molecules such as pigments in Chinese herbal volatile oils can be attached to the pore surface and active sites of activated carbon through physical adsorption. During the decolorization process, the Chinese herbal volatile oils are mixed with activated carbon, and after a certain period of stirring or standing, the pigments and other impurities are adsorbed by the activated carbon, thereby achieving the purpose of decolorizing the Chinese herbal volatile oils and improving the purity and quality of the volatile oils.

[0064] Adjust working parameters: RFID reader / writer 3 identifies the formula model of the Chinese medicine volatile oil in the liquid storage bottle 4, inputs the amount of clothing, which is the number or weight of clothing 7, adjusts the ultrasonic atomization power of the Chinese medicine atomization device according to the viscosity value and surface tension value of the Chinese medicine volatile oil, adjusts the maximum heating temperature of the heating device according to the composition of the Chinese medicine volatile oil, and adjusts the atomization fumigation time and the wind speed of the heating device according to the amount of clothing. Chinese medicine volatile oils with different formulas have different viscosity values ​​and surface tension values. Viscosity and surface tension will affect the difficulty of the Chinese medicine liquid to form droplets under the action of the ultrasonic atomization sheet 43. For example, Chinese medicine volatile oils with higher viscosity require greater ultrasonic atomization power to effectively break them into tiny droplets; while volatile oils with lower surface tension are relatively easy to atomize, and the required ultrasonic atomization power is smaller. After the RFID reader 3 identifies the formula model of the Chinese medicine volatile oil, the device controller automatically adjusts the ultrasonic atomization power of the Chinese medicine atomization device according to the viscosity and surface tension data of the different formula volatile oils stored in advance, so as to ensure that the Chinese medicine volatile oil can be efficiently atomized into a suitable droplet size and concentration. The components of Chinese medicine volatile oil are complex and diverse, and the volatility characteristics of different components are different. Some heat-sensitive components may decompose or deteriorate at too high a temperature, affecting the efficacy. Therefore, it is necessary to adjust the maximum heating temperature of the heating device through the device controller according to the specific components of the Chinese medicine volatile oil. For example, for Chinese medicine volatile oil containing more heat-sensitive components, the maximum heating temperature can be appropriately reduced, which can not only ensure the volatilization effect of the volatile oil, but also avoid the loss of components; while for components with weaker volatility, the heating temperature can be appropriately increased to promote its volatilization. At different temperatures, the components of the volatile oil are analyzed by gas chromatography-mass spectrometry experiments to determine the critical temperature value of the decomposition of the effective components, which is used as the setting value of the maximum heating temperature Tmax of the heating device.

[0065] The amount of clothing directly affects the time for drug penetration and the required hot air flow rate. When the amount of clothing is large, a longer atomization fumigation time is required to ensure that enough drugs can adhere to and penetrate into the clothing 7; at the same time, in order to ensure that the hot air can be evenly distributed around the clothing 7 and promote the diffusion and penetration of the drug, it is necessary to appropriately increase the wind speed of the heating device. Conversely, when the amount of clothing is small, the atomization fumigation time can be shortened and the wind speed can be reduced. The device controller automatically adjusts the atomization fumigation time and the wind speed of the heating device according to the input clothing amount information and the preset algorithm to achieve accurate drug coating production.

[0066] The ultrasonic atomization power is P:

[0067] P=kη×σ b ×f 2 ×d 3

[0068] Where η is the liquid viscosity, σ is the liquid surface tension, f is the ultrasonic frequency, d is the atomized droplet diameter, and k and b are constants determined by fitting experimental data.

[0069] Preheating: The heating device is pneumatically preheated until the temperature of the volatilization zone 21 reaches and is maintained at the maximum heating temperature. After the heating device is started, the fan 62 draws outside air into the air inlet chamber 63, and after being heated by the heating element 61, the hot air enters the volatilization zone 21. The temperature sensor monitors the temperature of the volatilization zone 21 in real time and feeds the data back to the equipment controller. The controller adjusts the power of the heating element 61 and the speed of the fan 62 according to the set maximum heating temperature, so that the temperature of the volatilization zone 21 rises rapidly and is stably maintained at the maximum heating temperature. This process provides a stable and suitable thermal environment for the subsequent rapid fumigation stage, ensuring that the volatile oil of traditional Chinese medicine can volatilize and penetrate under optimal temperature conditions.

[0070] After the preheating is completed, the inner drum 1 is controlled to rotate and enter the rapid fumigation stage. After the preheating is completed, the rotating mechanism drives the inner drum 1 to start rotating. The rotation of the inner drum 1 can make the clothes 7 constantly change their positions in the volatilization zone 21, fully contact the hot air and the Chinese medicine droplets or steam, and promote the uniform distribution of the medicine on the clothes 7. At the same time, the shaking of the fibers of the clothes 7 during the rotation process also helps the drug molecules to better penetrate into the fibers, thereby improving the quality of the medicine coating.

[0071] The device also has a user interaction module, which usually includes one or more input and output devices such as a display screen, buttons, and a touch screen. From the input perspective, the user can input various instructions through buttons or touch screens, such as starting the device, setting drug coating production parameters, etc. These input signals are converted into electrical signals and transmitted to the controller. From the output perspective, the display screen is used to feedback the working status of the device to the user, such as the current fumigation stage, the temperature of the volatilization zone 21, the remaining production time and other information. At the same time, when the device fails or the user needs to perform certain operations, the display screen will also display corresponding prompt information to achieve two-way information interaction between the user and the device. In other optional embodiments, the mobile phone APP can be further connected via Bluetooth communication.

[0072] The device also includes a power management module, which is connected to an external power source to convert and distribute the input electrical energy. It first stabilizes the input voltage to ensure that the components of the device work at a stable voltage to avoid damage to the device due to voltage fluctuations. Then, the electrical energy is distributed to each module according to the power consumption requirements of different components. For example, sufficient electrical energy is provided for a high-power heating device and motor, while a suitable operating voltage is provided for low-power controllers, RFID readers and writers 3 and other modules. In addition, the power management module also has overcurrent protection, overvoltage protection and undervoltage protection functions. When abnormal current and voltage are detected in the circuit, the power supply is cut off in time or corresponding protection measures are taken to ensure the safe operation of the equipment.

[0073] The controller of the device realizes the intelligent operation of the device. The controller is an embedded control module, which can automatically adjust the working parameters of each component of the device, such as ultrasonic atomization switch and power, heating switch and temperature, fan 62 switch and wind speed, inner drum 1 rotation speed, timing function, Bluetooth communication data interaction, cover 51 closed state recognition and atomization fumigation duration, etc., according to different Chinese medicine volatile oil formula models and user input information such as clothing quantity. This intelligent control avoids the tediousness and inaccuracy of manual parameter adjustment, and improves the efficiency and quality stability of drug clothing production. The controller monitors the working status of each component of the device in real time, and can timely detect possible faults of the device, such as heating element 61 failure, ultrasonic atomization sheet abnormality, etc., by analyzing sensor data and component feedback signals. Once a fault is detected, the controller immediately takes corresponding treatment measures, such as stopping the relevant components from working, starting the alarm system, prompting the user through the user interaction module, and recording the fault information for subsequent maintenance personnel to check and repair, to ensure the safe and reliable operation of the equipment.

[0074] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
