Description

Technical Field

[0001] This invention relates to the field of traditional Chinese medicine medical technology, specifically to a traditional Chinese medicine fumigation device for treating rhinitis. Background Technology

[0002] Rhinitis is an inflammatory reaction of the nasal mucosa and submucosal tissues caused by viral infections, bacterial infections, irritants, etc. Clinical symptoms often include nasal congestion, runny nose, nasal itching, throat discomfort, and cough. In severe cases, it can affect a patient's normal life and sleep quality. Traditional treatments for rhinitis often involve oral medications and nasal sprays. Some medications are slow to take effect, and long-term use can easily lead to side effects, impacting the patient's health. Traditional Chinese medicine fumigation is a commonly used physical therapy for rhinitis. It utilizes the steam generated by heating medicinal herbs to directly act on the affected area in the nasal cavity, achieving a good effect of clearing the nasal passages and reducing inflammation. Chinese patent CN109009994B discloses a traditional Chinese medicine fumigation machine for rhinitis, comprising a horizontal plate, elastic ropes, hanging rings, rubber tubes, a first spring, a bearing seat, a locking rod, a U-shaped frame, a rotating rod, a push block, an air inlet pipe, a frame, and a placement frame. Elastic ropes are connected to both sides of the horizontal plate, with hanging rings installed at the ends of the ropes. Symmetrical through-holes are opened on both sides of the horizontal plate, and a rubber tube is installed between these through-holes. This invention allows steam to be directly injected into the patient's nose via the rubber tube, avoiding the waste of large amounts of steam floating in the air. Furthermore, the hanging rings make it easier to hang the device on the face for convenient steam fumigation of the patient's nose.

[0003] The aforementioned patent describes a method of dissolving the effective therapeutic components of traditional Chinese medicinal herbs in water through steaming, and then generating steam by heating to boiling to achieve a fumigation effect. While this patented method can extract the effective components of traditional Chinese medicinal herbs and achieve the fumigation effect, it has the following problems: 1. Conventional steaming methods operate under standard atmospheric pressure, resulting in a slower rate of extraction of the active ingredients from medicinal herbs. Compared to extraction under high pressure, extracting the same amount of active ingredients requires more water to dissolve the extracted components under standard atmospheric pressure. Therefore, to ensure the inhalation of effective therapeutic components during each fumigation treatment, patients need to spend a significant amount of time and inhale large amounts of medicinal vapor with low concentrations of active ingredients. Prolonged fumigation not only wastes the patient's time but also increases discomfort during the treatment.

[0004] 2. The fumigation steam obtained by boiling is at a high temperature, far exceeding the expected warm and penetrating fumigation treatment effect. To avoid discomfort to patients caused by high-temperature steam, the above patent adds a cooling mechanism. However, the cooling method is achieved by introducing steam into the heat exchange pipe, which is to achieve the cooling effect by exchanging heat between high-temperature steam and cold water. This cooling method is difficult to control the specific cooling temperature. Secondly, the cooling process is prone to excessive cooling, which leads to steam condensation, reduces the steam concentration and fumigation effect, and thus reduces the treatment effect. Summary of the Invention

[0005] The purpose of this invention is to provide a traditional Chinese medicine fumigation device for treating rhinitis, so as to solve the problems mentioned in the background art of the prior art for treating rhinitis, such as long treatment time, increased patient discomfort, and difficulty in controlling the fumigation temperature.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a traditional Chinese medicine fumigation device for treating rhinitis, comprising a heating boiler and a booster pump for replenishing water and pressurizing the heating boiler.

The escape shield is connected to a breathing mask through a medicine supply pipe. The cavity of the piston head away from the flexible tube is connected to the water outlet of the booster pump through a pressurizing pipe.

[0007] Preferably, the outlet of the booster pump is connected to the heating boiler via a boiler water supply pipe, and the heating boiler is equipped with an integrated temperature and pressure sensor and a liquid level sensor; a vacuum breaker valve is installed on the top of the heating boiler.

[0008] Preferably, the extraction head is configured as a hollow disc-shaped structure, the top of the extraction head is connected to the water outlet of the heating boiler through a pipe, and the bottom of the extraction head is evenly provided with several water outlet holes; the extraction spoon is configured as a spoon-shaped structure, and the bottom of the extraction spoon is evenly provided with several medicine outlet holes; a sealing docking mechanism is provided between the extraction head and the extraction spoon.

[0009] Preferably, the sealing and docking mechanism includes a sleeve portion integrally formed with the extraction head, the sleeve portion being located on the side where the water outlet is located, the space inside the sleeve portion forming a snap-fit ​​interface that docks with the mouth of the extraction spoon, a plurality of female buckles being evenly arranged on the inner circumferential direction of the sleeve portion, and male buckles corresponding one-to-one with the female buckles being evenly arranged on the outer circumferential direction of the mouth of the extraction spoon; a sealing gasket is provided on the inner side of the sleeve portion and close to the wall surface where the water outlet is located.

[0010] Preferably, the boiler water supply pipe is equipped with a solenoid valve one, the water inlet end of the pressurization pipe is connected between the water outlet end of the booster pump and the solenoid valve one, and a one-way valve and a solenoid valve four are arranged sequentially on the pressurization pipe according to the water flow direction.

[0011] Preferably, a second heating wire is installed inside the escape shield, and a temperature sensor is installed inside the escape shield.

[0012] Preferably, a light-transmitting tube is connected to the top of the medicine storage cylinder and the end near the atomizing nozzle. A non-contact liquid level sensor is installed outside the light-transmitting tube, and a solenoid valve is installed on the light-transmitting tube between the non-contact liquid level sensor and the medicine storage cylinder.

[0013] Preferably, it also includes a backwashing pipeline, which includes a backwash pipe, one end of which is connected to a pressurizing pipe, and the other end of which is connected to the drug receiving cavity of the drug storage cylinder. A solenoid valve seven is installed on the backwash pipe. A solenoid valve six is ​​installed on the pipeline between the drug storage cylinder and the atomizing nozzle. A drain pipe two, which is connected to the drug receiving cavity, is installed at the bottom of the drug storage cylinder. A solenoid valve eight is installed on the drain pipe two. A drain pipe three is connected to the pressurizing pipe between the solenoid valve four and the drug storage cylinder. A solenoid valve nine is installed on the drain pipe three.

[0014] Preferably, a pressure relief valve one is connected in parallel with the heating boiler to the boiler water supply pipe; and a pressure relief valve two is connected in parallel with the chemical storage cylinder to the pressurization pipe.

[0015] Preferably, the extraction spoon is provided with a handle on the outside, and the hose is connected to the bottom of the extraction spoon through a collecting funnel.

[0016] Compared with the prior art, the beneficial effects of the present invention are: 1. This invention employs a high-temperature water and high-pressure extraction method to extract the effective therapeutic components from traditional Chinese medicinal materials. Firstly, the high-temperature and high-pressure extraction significantly reduces the drug precipitation time. Secondly, it reduces the amount of water required for drug precipitation, increasing the content of effective components in the liquid while reducing the volume of the liquid. This further reduces the time required for subsequent drug atomization and evaporation. Compared to prolonged boiling extraction under normal pressure, this device effectively shortens the overall duration of fumigation treatment for patients and reduces discomfort during treatment.

[0017] 2. This invention uses a piston-like extrusion method to push a liquid containing a high concentration of drug components into the atomizing nozzle, which can stably obtain atomized drug particles with a stable concentration and controllable temperature for patients to inhale for treatment. There is no need to cool down the large volume of high-temperature steam, avoiding the waste of effective ingredients caused by the condensation of drug steam during the cooling process, and ensuring the effect of fumigation treatment.

[0018] 3. In this invention, through the sealed connection between the extraction head and the extraction spoon, high-pressure hot water is squeezed out from the water outlet of the extraction head and directly passes through the Chinese herbal medicine particles contained in the extraction spoon. After the high-pressure water extracts the effective components of the Chinese herbal medicine, it directly enters the collection pipeline through the medicine outlet at the bottom of the extraction spoon, thus directly completing the extraction and collection of the effective components of the Chinese herbal medicine. The device has a compact structure and a simple operation process.

[0019] 4. This invention adds a backwashing pipeline, which can directly perform high-pressure backwashing on each pipeline of the device after the extraction operation is completed, and directly discharge the residual drug residue and drug liquid impurities in the pipeline from the device, avoiding the deterioration of residual drugs and contamination of the next treatment operation. There is no need to manually disassemble the device for cleaning, which greatly improves the convenience of using the device.

[0020] 5. This invention, through ingenious pipeline design, uses only one booster pump to complete the high-temperature and high-pressure extraction of drugs, atomization of drug solution, backwashing of drug storage cylinder, and piston head reset function. This makes the device comprehensive in function, reusable, and easy to operate, while reducing the material cost and volume of the device. Attached Figure Description

Detailed Implementation

[0023] The technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0024] like Figures 1 to 4 As shown, a traditional Chinese medicine fumigation device for treating rhinitis includes a heating boiler 3 and a booster pump 2 for replenishing water and pressurizing the heating boiler 3. The water outlet of the heating boiler 3 is connected to an extraction head 4.

[0025] It also includes an extraction spoon 5 that works in conjunction with the extraction head 4. The liquid outlet of the extraction spoon 5 is connected to the drug storage cylinder 6 via a hose 51. A piston head 61 is slidably installed in the inner cavity of the drug storage cylinder 6. An atomizing nozzle 7 is connected to the cavity of the piston head 61 facing the hose 51. An escape shield 71 is installed at the spray nozzle of the atomizing nozzle 7. The escape shield 71 is connected to a breathing mask 73 via a drug supply pipe 72. The cavity of the piston head 61 away from the hose 51 is connected to the water outlet of the booster pump 2 via a pressurizing pipe 8.

[0026] In this embodiment, the inlet of the booster pump 2 can be directly connected to an external tap water source, or it can be connected to a container used to store water. The container can be a water storage tank 1 or the like, and the specific setting method is not limited.

[0027] Specifically, in this embodiment, the outlet of the booster pump 2 is connected to the heating boiler 3 through the boiler water supply pipe 37. The heating boiler 3 is equipped with a temperature and pressure integrated pressure sensor 33 and a liquid level sensor 34. The temperature and pressure integrated pressure sensor 33 is used to monitor the temperature and pressure inside the heating boiler 3 in real time so as to heat or pressurize the water inside the heating boiler 3 in a timely manner. The liquid level sensor 34 is used to monitor the water level inside the heating boiler 3 in real time so as to replenish water to the heating boiler 3 in a timely manner.

[0028] Specifically, in this embodiment, the water inside the heating boiler 3 is heated by a heating wire 36, which is also called a heating resistor and can quickly heat the stored water to over 90 degrees Celsius.

[0029] Furthermore, a vacuum breaker valve 35 is provided on the top of the heating boiler 3. The vacuum breaker valve 35 can discharge the ineffective air inside the boiler body when the heating boiler 3 is heating, and at the same time avoid damage to the boiler body caused by negative pressure generated when the internal temperature of the heating boiler 3 drops after use.

[0030] like Figure 5 and Figure 6 As shown, the extraction head 4 is configured as a hollow disc-shaped structure. The top of the extraction head 4 is connected to the water outlet of the heating boiler 3 through a pipe. The bottom of the extraction head 4 is evenly provided with several water outlet holes 401. The extraction spoon 5 is configured as a spoon-shaped structure. The bottom of the extraction spoon 5 is evenly provided with several medicine outlet holes 501, which form the liquid outlet end of the extraction spoon 5. A sealing docking mechanism is provided between the extraction head 4 and the extraction spoon 5.

[0031] In one specific embodiment, the sealing and docking mechanism includes a sleeve portion 402 integrally formed with the extraction head 4. The sleeve portion 402 is located on the side where the water outlet 401 is located. The space inside the sleeve portion 402 forms a snap-fit ​​interface for docking with the ladle mouth of the extraction spoon 5. Multiple female buckles 403 are evenly arranged on the inner circumferential direction of the sleeve portion 402, and male buckles 503 corresponding to the female buckles 403 are evenly arranged on the outer circumferential direction of the ladle mouth of the extraction spoon 5. After inserting the ladle mouth of the extraction spoon 5 into the space inside the sleeve portion 402, rotating the extraction spoon 5 causes each male buckle 503 to overlap and lock with the corresponding female buckle 403, thereby achieving docking between the extraction head 4 and the extraction spoon 5. To ensure a tight seal between the extraction head 4 and the extraction spoon 5, a sealing gasket 41 is provided on the inner side of the sleeve portion 402, close to the water outlet 401. The shape of the sealing gasket 41 corresponds to the shape of the spoon opening of the extraction spoon 5. When the extraction spoon 5 is engaged, the edge of the spoon opening of the extraction spoon 5 compresses the sealing gasket 41, causing elastic deformation, thereby filling the gap between the two and preventing high-pressure hot water from leaking from the joint, thus ensuring stable pressure during the extraction process. In addition, in this embodiment, a flexible hose 51 is used to transitionally connect the extraction spoon 5 and the drug storage cylinder 6. The purpose is to ensure that the extraction spoon 5 has sufficient free space to move and rotate, so as to achieve the connection between the extraction spoon 5 and the extraction head 4.

[0032] Furthermore, the extraction spoon 5 is provided with a handle 502 on the outside to facilitate hand operation of the extraction spoon 5.

[0033] Specifically, in this embodiment, the tubing 51 is connected to the bottom of the extraction spoon 5 via a collecting funnel 511, and the collecting funnel 511 is used to collect the extracted medicinal liquid and introduce it into the tubing 51.

[0034] In this embodiment, a solenoid valve 32 is installed on the connecting pipe between the heating boiler 3 and the extraction head 4. When the traditional Chinese medicine extraction is not being performed, the solenoid valve 32 is normally closed to prevent water inside the heating boiler 3 from flowing into the extraction head 4.

[0035] Specifically, a solenoid valve 31 is installed on the boiler water supply pipe 37, the water inlet end of the pressurization pipe 8 is connected between the water outlet end of the booster pump 2 and the solenoid valve 31, and a one-way valve 81 and a solenoid valve 82 are installed on the pressurization pipe 8 in sequence according to the water flow direction.

[0036] Traditional Chinese Medicine Extraction Principle: Before extraction, the herbs are ground into powder and added to the extraction spoon 5. Care should be taken to evenly fill the spoon 5 with the powder. The spoon 5, now containing the powder, is then sealed to the extraction head 4. Next, solenoid valve 1 (31) is opened, while solenoid valves 2 (32) and 4 (82) are closed. Water is introduced into the heating boiler 3 via the booster pump 2, and the water inside the boiler is heated to above 90 degrees Celsius via heating wire 36, preferably to 95-98 degrees Celsius. Once the water in the boiler reaches the designated temperature, extraction begins. At this time, solenoid valve 2 (32) opens, and the booster pump 2 continuously pressurizes the heating boiler 3. The extraction pressure in the heating boiler 3 is adjusted according to a preset pressure; for example, the extraction pressure for common woody medicinal materials is typically 8-15 bar. Under water pressure, high-temperature water enters the extraction head 4 and flows into the extraction spoon 5 through the water outlet 401. The high-temperature water entering the extraction spoon 5 passes through the ground Chinese medicine powder. Under high temperature and high pressure, the effective components in the Chinese medicine quickly dissolve in the water and flow out through the medicine outlet 501 at the bottom of the extraction spoon. After being collected by the collection funnel 511, the medicine liquid enters the medicine storage cylinder 6 through the hose 51. The solenoid valve 1 31 and the solenoid valve 2 32 are closed, completing the extraction process of the Chinese medicine.

[0037] Furthermore, to further improve extraction stability and enhance the extraction effect of the traditional Chinese medicine solution, a pressure relief valve 11 connected in parallel with the heating boiler 3 is provided on the boiler water supply pipe 37 to prevent excessive extraction pressure and protect the pipeline and heating boiler.

[0038] It should be noted that during the extraction of traditional Chinese medicine, the outflowing high-temperature water and the inflowing low-temperature water will cause the water temperature inside the heating boiler 3 to drop slightly. At this time, after the temperature drops below the specified temperature by the integrated temperature and pressure sensor 33, the heating wire 36 should be turned on and continuously heat the water below the specified temperature to ensure the stability of the extraction water temperature.

[0039] Preferably, the water storage volume of the heating boiler 3 is set at 1-2L. This capacity setting is moderate, ensuring that there is enough water for extraction, without causing problems such as excessive heating time and high heating cost due to excessive water volume.

[0040] The principle of traditional Chinese medicine fumigation: The piston head 61 divides the internal space of the medicine storage cylinder 6 into two chambers. The chamber facing the hose 51 forms a medicine receiving chamber for storing the traditional Chinese medicine liquid, and the chamber facing the pressurization pipe 8 forms a pressurization chamber for receiving the water flow pumped in by the booster pump 2. After the extracted traditional Chinese medicine liquid enters the medicine receiving chamber, the fumigation preparation stage begins. At this time, solenoid valve 31 is closed and solenoid valve 84 is opened. The booster pump 2 pressurizes the water through the pressurization pipe 8 and pumps it into the pressurization chamber. As the water pressure increases, the pressure inside the pressurization chamber also increases. When the pressure inside the pressurization chamber is greater than the pressure inside the medicine receiving chamber, the piston head 61 moves towards the medicine receiving chamber under the pressure difference, thereby squeezing the traditional Chinese medicine liquid in the medicine receiving chamber and forcing the traditional Chinese medicine liquid into the atomizing nozzle 7. Finally, the atomizing nozzle 7 atomizes the traditional Chinese medicine liquid and delivers it to the breathing mask 73 through the medicine supply pipe 72 for the user to inhale through the nasal cavity to complete the fumigation treatment.

[0041] The function of the anti-escape cover 71 is to collect the atomized Chinese medicine liquid and improve the delivery efficiency of the medicine mist.

[0042] Furthermore, the interior of the anti-escape shroud 71 is equipped with a second heating wire 74, which heats the medicinal mist to prevent condensation and backflow, enhances the "heat flow upward" effect of the medicinal mist, and improves the delivery efficiency of the medicinal mist. At the same time, heating the medicinal mist quickly achieves the "fumigation" effect of the drug.

[0043] Furthermore, a temperature sensor (not shown in the figure) is installed inside the escape shield 71 to monitor the temperature of the drug mist in real time and prevent the temperature from being too high and causing discomfort to the patient.

[0044] Furthermore, a light-transmitting tube 91 is connected to the top of the medicine storage cylinder 6 and the end near the atomizing nozzle 7. A non-contact liquid level sensor 92 is provided outside the light-transmitting tube 91, and a solenoid valve 93 is provided on the light-transmitting tube 91 and located between the non-contact liquid level sensor 92 and the medicine storage cylinder 6. In the initial stage of pressurizing the medicine storage cylinder 6 by pumping water into the pressurization chamber by the booster pump 2, the solenoid valve 93 is in the open state. Since there is excess air in the medicine receiving chamber of the medicine storage cylinder 6, during the initial pressurization stage, as the piston head 61 compresses the medicine receiving chamber, the excess air inside the medicine receiving chamber will be discharged to the outside through the light-transmitting tube 91 until the Chinese herbal extract enters the light-transmitting tube 91. At this time, the non-contact liquid level sensor 92 detects that the medicine has entered the light-transmitting tube 91, proving that the air has been discharged. Then, the solenoid valve 93 is immediately closed. At this time, only the medicine remains in the medicine receiving chamber. During the subsequent medicine atomization process, the atomizing nozzle only atomizes the medicine, and no air enters the atomizing nozzle, thus improving the atomization effect of the medicine. At the same time, during the medicine extraction stage, the solenoid valve 93 is in the normally open state to balance the air pressure between the medicine storage cylinder 6 and the outside, ensuring that the extracted medicine can smoothly enter the medicine storage cylinder 6 through the hose 51.

[0045] Furthermore, a pressure relief valve 12 connected in parallel with the medicine storage cylinder 6 is connected to the pressurization pipe 8 to prevent excessive pressure in the pressurization chamber and protect the pipeline.

[0046] Furthermore, it also includes a backflushing line for cleaning the drug-containing cavity of the drug storage cylinder 6.

[0047] In one specific embodiment, the backwashing pipeline includes a backwashing pipe 10. One end of the backwashing pipe 10 is connected to the pressurizing pipe 8, specifically connected to the pipeline section between the one-way valve 81 and the solenoid valve 82. The other end of the backwashing pipe 10 is connected to the drug receiving chamber of the drug storage cylinder 6. A solenoid valve 102 is installed on the backwashing pipe 10. A solenoid valve 101 is installed on the pipeline between the drug storage cylinder 6 and the atomizing nozzle 7 (the end of the backwashing pipe 10 connected to the drug receiving chamber of the drug storage cylinder 6 is specifically connected to the pipeline section between the drug storage cylinder 6 and the solenoid valve 101). A drain pipe 103 connected to the drug receiving chamber is installed at the bottom of the drug storage cylinder 6, and a solenoid valve 104 is installed on the drain pipe 103. Simultaneously, a drain pipe 105 is connected to the pressurizing pipe 8 located between the solenoid valve 82 and the drug storage cylinder 6, and a solenoid valve 106 is installed on the drain pipe 105.

[0048] Piston head reset and backflushing principle: When the piston head 61 is reset, solenoid valves 31, 52, 82, 93, 101, and 104 are closed, while solenoid valves 102 and 106 are opened. The booster pump 2 pumps high-pressure water sequentially through the booster pipe 8 and backwash pipe 10 into the drug-containing chamber. Driven by the high-pressure water, the piston head 61 moves towards the booster chamber, completing its reset. As the piston head 61 moves towards the booster chamber, the space within the chamber decreases, and the water remaining inside is discharged to the outside through the drain pipe 105.

[0049] After piston head 61 is reset, backflushing begins. During backflushing, solenoid valves 1-31, 3-52, 4-82, 5-93, 6-101, and 9-106 are closed, while solenoid valves 7-102 and 8-104 are opened. High-pressure water enters the drug-containing cavity and flushes the cavity wall. The wastewater generated during flushing is discharged through drain pipe 2-103, completing the cleaning of the drug-containing cavity.

[0050] In this embodiment, the one-way valve 81 is located on the pipeline section between the booster pump 2 and the solenoid valve 82 to prevent the water entering the pressurization pipe 8 from flowing back and causing pollution, and to ensure that the water entering the heating boiler 3 is clean water.

[0051] Furthermore, it also includes a main sewage pipe 13, with the light-transmitting pipe 91 connected to the main sewage pipe 13 via a first sewage pipe 94; the second sewage pipe 103 and the third sewage pipe 105 are respectively connected to the main sewage pipe 13; the discharge ends of the first pressure relief valve 11 and the second pressure relief valve 12 are respectively connected to the main sewage pipe 13 via pipes, and all wastewater in the device is collected and discharged uniformly through the main sewage pipe 13.

[0052] This embodiment also includes a controller for controlling all the aforementioned electrical components. The controller is a programmable logic controller, such as a PLC controller. All solenoid valves, integrated temperature and pressure sensors, level sensors, temperature sensors, non-contact level sensors, booster pumps, heating wire one, and heating wire two are electrically connected to the controller. The controller uniformly schedules each component according to a preset program, automatically completing the entire process of traditional Chinese medicine extraction, fumigation, piston head reset, and backwashing. This eliminates the need for manual step-by-step adjustment of each valve, simplifying the operation process and achieving automated operation. The controller itself is existing conventional technology; the control process can be adaptively set according to the principle description provided by this invention, and the specific setting method will not be elaborated further.

[0053] It will be apparent to those skilled in the art that the present invention is not limited to the details of the exemplary embodiments described above, and that the invention can be implemented in other specific forms without departing from its spirit or essential characteristics. Therefore, the embodiments should be considered in all respects as exemplary and non-limiting, and the scope of the invention is defined by the appended claims rather than the foregoing description. Thus, all variations falling within the meaning and scope of equivalents of the claims are intended to be included within the present invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
