Abstract
Description
Technical Field
[0001] This utility model relates to the field of medical device technology, and in particular to a moxibustion blowing device. Background Technology
[0002] Moxibustion blowing is a traditional Chinese medicine therapy originating from the *Huangdi Neijing* (Yellow Emperor's Inner Classic). It primarily involves blowing the smoke from burning moxa sticks or moxa wool onto the affected area (especially lesions with cavities) or acupoints for treatment. It has the effects of warming the meridians and collaterals, tonifying the five internal organs, and purging pathogenic factors. Based on current clinical applications, the efficacy of moxibustion blowing is confirmed. Traditionally, moxibustion blowing involves blowing the smoke from moxa sticks or cones onto the affected area or acupoints. However, this method is inconvenient, and the smoke tends to disperse easily and is difficult to concentrate on the affected area, resulting in insufficient efficacy.
[0003] With the development of technology, the blowing moxibustion device has emerged. After being powered on, the moxa stick is lit and inserted into the outer casing with the blowing head. The blower inside the casing blows the smoke produced by the burning moxa stick towards the blowing head, and then through the air outlet of the blowing head to the affected area. However, existing blowing moxibustion devices have poor versatility and can only be used for blowing moxibustion on patients. If patients also need regular moxibustion treatment, a separate moxibustion treatment device is required, which increases the purchase cost of medical equipment and the storage space required. Utility Model Content
[0004] This invention aims to solve at least one of the technical problems existing in the prior art. To this end, this invention proposes a blowing moxibustion device that is versatile and can simultaneously perform blowing moxibustion and regular moxibustion treatments on patients, saving on the purchase cost and storage space of medical devices and improving user satisfaction.
[0005] This utility model embodiment provides a blow-drying moxibustion device, which includes:
[0006] A blower device, which has an air outlet;
[0007] A moxa smoke production device includes an air duct and a storage chamber for storing moxa wool. The storage chamber is located below the air duct. The air duct has an air inlet and an air outlet at opposite ends. The air inlet and outlet are connected by a pipe. The upper part of the storage chamber has a first grid plate with multiple through-holes that connect the air duct and the storage chamber, allowing moxa smoke to flow from the storage chamber to the air duct. The lower part of the storage chamber has a second grid plate with multiple through-holes that connect the storage chamber to the outside atmosphere, allowing the heat energy from the burning moxa wool to be transferred downwards when the moxa smoke production device is placed on the moxibustion site.
[0008] A handheld smoke spraying device has a smoke outlet and a smoke inlet, wherein the smoke inlet is connected to the airflow outlet via a pipe.
[0009] The moxibustion device according to this embodiment of the present invention has at least the following beneficial effects: When a certain amount of moxa wool is placed in the storage chamber of the moxa smoke production device, the moxa wool is ignited to produce moxa smoke. Furthermore, by activating the blower, air is blown into the air duct. Under the action of the high-speed airflow, the moxa smoke flows from the storage chamber through the first grid plate to the air duct and towards the smoke outlet of the handheld smoke sprayer. The operator can then hold the handheld smoke sprayer and spray the moxa smoke onto the lesion for moxibustion treatment. Moreover, when the patient requires regular moxibustion treatment, the operator can place the moxa smoke production device on the moxibustion site, allowing the heat generated by the burning moxa wool to be transferred to the moxibustion site through the second grid plate for regular moxibustion treatment.

The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain this utility model, and should not be construed as limiting this utility model.
[0027] In the description of this utility model, it should be understood that features specified as "first" or "second" may explicitly or implicitly include one or more of those features. In the description of this utility model, unless otherwise stated, "multiple" means two or more.
[0028] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.
[0029] The following is for reference. Figures 1 to 5 This invention describes a moxibustion device provided according to an embodiment of the present invention.
[0030] like Figures 1 to 3 As shown, the blowing moxibustion device according to the embodiment of this utility model has the advantages of unique structural design, good versatility and practicality. The blowing moxibustion device of this embodiment can simultaneously perform blowing moxibustion treatment and ordinary moxibustion treatment on patients, thus saving the purchase cost and storage space of medical devices, thereby improving the user satisfaction of the blowing moxibustion device product and enhancing the market competitiveness of the blowing moxibustion device product.
[0031] The structure of the moxibustion device includes a blower 100, a smoke production device 300, and a handheld smoke spraying device 500.
[0032] The blower 100 has an air outlet. It can be understood that the function of the blower 100 is to supply air to the smoke production device 300. The blower 100 can be a fan or a foot-operated air pump.
[0033] The moxa smoke production device 300 includes an air duct 301 and a storage chamber 302. The storage chamber 302 is used to hold moxa wool 600 and is located below the air duct 301. The moxa wool 600 can burn within the storage chamber 302 to produce moxa smoke. The air duct 301 extends horizontally, with an air inlet and an air outlet at opposite ends. The air inlet of the air duct 301 is connected to the air outlet of the blower 100 via a pipe such as the first connecting pipe 200, allowing the blower 100 to deliver air into the air duct 301.
[0034] The upper part of the storage cavity 302 is provided with a first grid plate 303, which has multiple first mesh holes that extend from top to bottom, connecting the ventilation duct 301 to the storage cavity 302 so that the moxa smoke can flow from the storage cavity 302 to the ventilation duct 301. The lower part of the storage cavity 302 is provided with a second grid plate 304, which has multiple second mesh holes that extend from top to bottom, connecting the storage cavity 302 to the outside atmosphere so that when the moxa smoke generating device 300 is placed on the moxibustion site, the heat from the combustion of the moxa wool 600 (i.e., the heat generated by the combustion of the moxa wool 600) can be transferred downwards to the patient's moxibustion site.
[0035] It is understood that the first and second mesh openings can be round, square, or other shaped holes, and their aperture sizes can be set according to actual needs, without specific limitations here. The first mesh plate 303 serves as a filter barrier between the storage chamber 302 and the air duct 301. The first mesh opening on the first mesh plate 303 can prevent the moxa wool 600 and the moxa ash produced by its combustion from entering the air duct 301. During the process of the blower 100 supplying air to the air duct 301, the moxa wool 600 located in the storage chamber 302, due to the drainage effect, causes the moxa smoke to flow into the air duct 301 through the first mesh opening. The second mesh plate 304 serves as a filter barrier between the storage chamber 302 and the external atmosphere. The second mesh opening on the second mesh plate 304 can prevent the moxa wool 600 and moxa ash from falling out of the storage chamber 302. Some of the moxa smoke can flow out of the storage chamber 302 through the second mesh opening to heat the patient's moxibustion area.
[0036] The handheld smoke spraying device 500 has a smoke outlet 511 and a smoke inlet. The smoke inlet is connected to the airflow outlet of the moxa smoke production device 300 through a pipe such as the second connecting pipe 400. Therefore, the moxa smoke in the air duct 301 can flow to the handheld smoke spraying device 500 under the action of the blower and be sprayed out through the smoke outlet 511 to perform moxibustion treatment on the patient's lesion.
[0037] In the process of using the blowing moxibustion device of this embodiment, when a certain amount of moxa wool 600 is placed in the storage chamber 302 of the moxa smoke generating device 300, the moxa wool 600 is ignited to generate moxa smoke. Moreover, by activating the blower device 100, the blower device 100 blows air into the air duct 301. Under the action of the high-speed airflow, the moxa smoke can flow from the storage chamber 302 through the first mesh of the first grid plate 303 into the air duct 301 and flow towards the smoke outlet 511 of the handheld smoke spraying device 500. Then, the operator, such as a medical staff, can hold the handheld smoke spraying device 500 and spray the moxa smoke at the lesion to perform blowing moxibustion treatment on the patient. Moreover, when the patient still needs ordinary moxibustion treatment, the operator can place the moxa smoke generating device 300 on the moxibustion site, so that the heat generated by the burning moxa wool 600 can be transferred to the moxibustion site through the second mesh of the second grid plate 304 to heat the patient, thereby completing the ordinary moxibustion treatment.
[0038] The blowing moxibustion device in this embodiment adopts such a unique structural design that it can enable the blowing moxibustion device to have the dual functions of blowing moxibustion treatment and ordinary moxibustion treatment, increasing the versatility of the blowing moxibustion device. It eliminates the need to equip the blowing moxibustion treatment and ordinary moxibustion treatment with corresponding treatment instruments, thereby saving the purchase cost and storage space of medical devices.
[0039] In this embodiment, as Figure 1 and Figure 2 As shown, the structure of the moxa smoke production device 300 includes an upper housing 310, a lower support base 320, and a backflow smoke device 330. The upper housing 310 has a first groove and an air duct 301. The opening of the first groove faces downwards and is located below the air duct 301. A first mesh plate 303 is provided between the first groove and the air duct 301, and the first mesh plate 303 is fixedly connected to the upper housing 310, separating the first groove and the air duct 301. Furthermore, the upper housing 310 and the lower support base 320 are detachably connected, for example, by screws, a rotating snap-fit, or a sleeve connection, so that the first groove and the lower support base 320 together form a storage cavity 302. When the lower support base 320 is separated from the upper housing 310, the backflow smoke device 330 can be placed or removed into the storage cavity 302.
[0040] The lower support base 320 includes legs 321 and a second mesh plate 304. At least three legs 321 are provided, and the upper ends of all legs 321 are fixedly connected to the second mesh plate 304. At least one backflow smoke device 330 is provided, and all backflow smoke devices 330 are located within the storage cavity 302. Each backflow smoke device 330 has a receiving cavity 333 for accommodating the moxa wool 600 and an air passage connecting the receiving cavity 333 and the storage cavity 302. In this embodiment, there are two backflow smoke devices 330.
[0041] Understandably, the support leg 321 provides the second grid plate 304 with a certain height. When the moxa smoke production device 300 is in the placement state, external air can enter the storage chamber 302 through the second mesh of the second grid plate 304, and then enter the receiving chamber 333 of the backflow smoke device 330 through the airflow hole, thus providing air for the combustion of the moxa wool 600. When the moxa wool 600 in the backflow smoke device 330 is ignited, the generated moxa smoke will flow into the storage chamber 302 through the airflow hole of the backflow smoke device 330. Most of the moxa smoke will be guided through the first mesh of the first grid plate 303 and quickly enter the air duct 301. At the same time, a small portion of the moxa smoke will overflow downwards through the second mesh of the second grid plate 304 and be blown towards the patient's moxibustion site to heat the patient.
[0042] In this embodiment, as Figures 1 to 3 As shown, the backflow smoke device 330 includes a housing 331 and a base 332. The housing 331 has a mesh-like perforated structure; specifically, through holes are provided on the upper surface and outer periphery of the housing 331. The housing 331 has a second groove with its opening facing downwards. The housing 331 and the base 332 are detachably connected so that the second groove and the base 332 together form a receiving cavity 333. After separating the housing 331 and the base 332, the moxa wool 600 can be placed in the receiving cavity 333. The base 332 includes support parts 335 and a third mesh plate 334. At least three support parts 335 are provided, and the upper ends of all support parts 335 are fixedly connected to the third mesh plate 334. The third mesh plate 334 has multiple airflow holes that are arranged vertically.
[0043] Understandably, the support 335 provides the third grid plate 334 with a certain height. When the backflow smoke device 330 is placed in the storage cavity 302, external air can flow sequentially through the second mesh of the second grid plate 304 and the airflow holes of the third grid plate 334, entering the receiving cavity 333 to provide oxygen for the moxa wool 600 to burn. After the moxa wool 600 at the bottom of the backflow smoke device 330 is ignited, it burns and produces moxa smoke. The moxa smoke can flow into the storage cavity 302 through the airflow holes of the third grid plate 334 and the through holes on the outer shell 331. Then, most of the moxa smoke, under the operation of the blower 100, flows rapidly into the air duct 301 through the first mesh of the first grid plate 303. At the same time, a small portion of the moxa smoke flows slowly downwards through the second mesh of the second grid plate 304 and flows towards the patient's moxibustion site.
[0044] Of course, when the third grid plate 334 and the second grid plate 304 are made of thermally conductive materials such as copper, when the moxa smoke production device 300 is placed on the moxibustion site and the moxa wool 600 is in a burning state, the heat from the combustion of the moxa wool 600 will radiate towards the moxibustion site through the third grid plate 334 and the second grid plate 304.
[0045] In this embodiment, as Figures 1 to 3 As shown, the base 332 is fitted onto the outer shell 331, and the lower support 320 is fitted onto the upper shell 310. This design facilitates the disassembly of the base 332 and the lower support 320. After disassembling the base 332 and the lower support 320, the moxa wool 600 is inserted from the bottom of the outer shell 331 and ignited. The base 332 is then fixedly connected to the bottom of the outer shell 331. Next, the entire backflow smoke device 330 is inserted from the bottom of the upper shell 310, and the lower support 320 is installed at the bottom of the upper shell 310.
[0046] In this embodiment, as Figures 1 to 3 As shown, the outer shell 331 is cylindrical when viewed vertically. Furthermore, the lower surface of the outer shell 331 has a recessed cavity 336 in the shape of an inverted cone or frustum. The cavity 336 is coaxially arranged with the outer shell 331, and its inner wall also has through holes. This design increases the airflow area between the receiving cavity 333 and the storage cavity 302, which helps to ensure complete combustion of the moxa wool 600 within the receiving cavity 333.
[0047] In this embodiment, the aperture of the airflow hole is larger than the aperture of the second mesh. In some examples, the moxa ash produced by burning the moxa wool 600 can fall down onto the second mesh plate 304 through the airflow hole on the third mesh plate 334. However, the aperture of the second mesh is designed to be small, preventing the moxa ash from passing through, causing the moxa ash to accumulate on the second mesh plate 304. Therefore, the moxa ash can be removed after removing the support base 320. In other examples, since moxa ash has anti-inflammatory, antibacterial, wound-healing, and pain-relieving effects, the aperture of the second mesh is designed to be large, allowing the moxa ash to pass through. The moxa ash can then fall down through the second mesh onto the patient's moxibustion area for cauterization and warm compress treatment.
[0048] In this embodiment, the pipe (i.e., the second connecting pipe 400) between the smoke inlet of the handheld smoke-spraying device 500 and the airflow outlet of the smoke-producing device 300 is a first corrugated hose 410. The length and diameter of the first corrugated hose 410 can be selected according to the actual situation and are not specifically limited here.
[0049] Furthermore, such as Figure 1 and Figure 2 As shown, the first corrugated hose 410 contains an insulation tube, which includes multiple soft, bulb-like structures 420. These bulb-like structures 420 are arranged sequentially and interconnected along the extension direction of the first corrugated hose 410. It can be understood that the multiple bulb-like structures 420 are integrally formed and possess a certain deformation capacity. When the air pressure inside the insulation tube is too high, the volume of the bulb-like structures 420 will increase, allowing them to hold more smoke, thus enabling the insulation tube to perform both smoke storage and heat preservation functions. The bulb-like structures 420 can be oblate or spherical. The connection between any two adjacent bulb-like structures 420 is a relatively small-diameter connecting neck.
[0050] In some embodiments, such as Figure 1 , Figure 4 and Figure 5 As shown, the handheld smoke-spraying device 500 includes a nozzle 510 and a smoke gun 520. The nozzle 510 has a smoke outlet 511, and the smoke gun 520 has a connection port and a smoke inlet. The nozzle 510 and the connection port can be detachably connected via a threaded structure. The nozzle 510 can be one of a conical nozzle, a duckbill nozzle, or a hood-type nozzle. If the nozzle 510 is a conical nozzle, there is one smoke outlet 511, located at the end of the nozzle 510 furthest from the smoke gun 520. The diameter of the smoke outlet 511 is relatively small. Figure 1 As shown. If the nozzle 510 is a duckbill-shaped nozzle, multiple smoke outlets 511 are provided, and they are evenly arranged around the outer circumference of the nozzle 510, such as... Figure 4As shown. If the nozzle 510 is a hood-type nozzle, there is one smoke outlet 511, located at the end of the nozzle 510 furthest from the smoke gun 520. The diameter of the smoke outlet 511 is relatively large, such as... Figure 5 As shown.
[0051] Understandably, different nozzles 510 can be used depending on the location of the lesion. The smoke gun 520 has a handle for the operator to hold.
[0052] In this embodiment, the blower 100 is a foot-operated air pump with an air outlet. The pipe (i.e., the first connecting pipe 200) between the air outlet and the airflow inlet of the moxa smoke production device 300 is a second corrugated flexible hose. The operator can operate the foot-operated air pump by stepping on it, allowing it to blow air into the moxa smoke production device 300. This design eliminates the need for electricity to operate the blower.
[0053] The moxibustion device provided in this embodiment can concentrate and continuously and evenly spray moxa smoke onto the lesion. Moreover, it can ensure a constant temperature of moxa smoke, improve the efficacy of moxibustion, and eliminate the need for mouth blowing, which helps to improve work efficiency.
[0054] Of course, it is possible that control valves, such as manual valves, are installed on the first connecting pipe 200 and the second connecting pipe 400.
[0055] In the description of this specification, the references to terms such as "one embodiment," "some embodiments," "illustrative embodiment," "example," "specific example," or "some examples," etc., indicate that a specific feature, structure, material, or characteristic described in connection with that embodiment or example is included in at least one embodiment or example of the present invention.
