Description

Technical Field

[0001] This utility model relates to the field of moxa smoke collection technology, and in particular to a moxa smoke collection and purification device. Background Technology

[0002] Moxibustion is a traditional treatment method that uses the heat generated by burning moxa sticks or cones made from mugwort leaves to stimulate acupoints or specific areas of the body. This stimulates the flow of Qi (vital energy) through the meridians, thereby regulating disordered physiological and biochemical functions and achieving the purpose of preventing and treating diseases. This therapy has the effects of warming the meridians and dispelling cold, promoting blood circulation, clearing the channels and meridians, and enhancing the body's disease resistance.

[0003] In clinical applications, existing moxa smoke collection devices in hospitals are generally large in size and limited in number, and are usually integrated with purification systems, resulting in insufficient mobility and flexibility. Medical staff find it difficult to effectively remove smoke from multiple patients receiving moxibustion treatment simultaneously using limited equipment, significantly restricting treatment efficiency. Furthermore, existing portable moxa smoke collection and purification devices generally have insufficient capture capacity at their smoke inlets, resulting in the inability to fully and effectively remove and collect the moxa smoke.

[0004] CN219764856U discloses a portable moxa smoke collection and filtration device, which includes a filter box and an extraction assembly to collect moxa smoke through a smoke collection hood. This device is designed for a single treatment point and can only serve one patient at a time. In actual hospital or clinic environments, moxibustion treatment often requires treating multiple patients simultaneously. This filtration device does not provide a mechanism for expanding to multi-patient scenarios; its mounting hardware is only suitable for fixing the device to a single hospital bed, failing to achieve resource sharing or flexible coverage of multiple locations. This approach leads to low treatment efficiency, requiring medical staff to configure a separate device for each patient, increasing equipment costs and space occupancy.

[0005] Therefore, there is an urgent need for a device that can adapt to multi-bed collaborative treatment scenarios, improve the efficiency of single-point smoking, and enable a single device to simultaneously support multiple patients.

[0006] Furthermore, on the one hand, there are differences in understanding among those skilled in the art; on the other hand, the applicant studied a large number of documents and patents when making this utility model, but due to space limitations, not all details and contents were listed in detail. However, this does not mean that this utility model does not have the features of these prior art. On the contrary, this utility model has all the features of the prior art, and the applicant reserves the right to add relevant prior art to the background art. Utility Model Content

[0007] In view of the shortcomings of the prior art, this application proposes a moxa smoke collection and purification device, and more particularly a moxa smoke collection and purification device for umbilical moxibustion, which aims to solve one or more technical problems in the prior art.

[0008] This invention proposes a moxa smoke collection and purification device, which includes a smoke-cleaning section, a collection section, and a rotating arm. The smoke-cleaning section is equipped with at least two collection sections, each of which is movably connected to the smoke-cleaning section via a corresponding rotating arm and can be unfolded and retracted by rotating the arm. An airflow channel is formed inside the rotating arm to connect the collection section and the smoke-cleaning section, so that the moxa smoke collected by the collection section during moxibustion can flow through the corresponding rotating arm and enter the smoke-cleaning section for purification. The collection section is equipped with a curtain and a telescopic channel. The telescopic channel is located at the top of the curtain. When the rotating arm rotates to unfold the collection section, the height of the telescopic channel is adjusted so that the curtain covers the moxibustion area. The telescopic channel is a vertical channel connecting the curtain and the rotating arm to improve the collection efficiency of moxa smoke by means of the chimney effect.

[0009] This device features a movable layout connecting the smoke-cleaning section and multiple collection sections via a rotating arm, enabling a single unit to simultaneously support multiple patients. The rotating arm's rotatable storage capability allows the collection sections to be flexibly expanded or retracted, significantly improving the device's spatial adaptability. The telescopic channel within the collection section, with its adaptive height adjustment, ensures that the curtain precisely covers different moxibustion sites, forming an effective enclosed space to prevent the escape of moxa smoke. The vertical design of the telescopic channel fully accommodates the natural upward movement of moxa smoke, enhancing the thermal pressure difference under the chimney effect, driving the moxa smoke to flow efficiently through the airflow channel inside the rotating arm to the smoke-cleaning section. This process not only improves the efficiency of moxa smoke collection but also reduces the suction energy required by the smoke-cleaning section and avoids smoke velocity attenuation caused by an unreasonable airflow path.

[0010] Preferably, the telescopic channel is equipped with several annular stainless steel rings as a support frame along its axial extension direction. These annular stainless steel rings, distributed along the axial direction of the telescopic channel, ensure that the channel maintains a stable vertical posture under different extension and contraction states. This rigid support structure effectively resists bending deformation caused by the channel's own weight or external disturbances, ensuring the straightness and continuity of the vertical airflow path. By maintaining the channel's vertical state, the chimney effect of the naturally rising hot smoke is utilized to the maximum extent, avoiding increased flow resistance caused by bends in the airflow path, thus ensuring that the smoke is efficiently and smoothly directionally delivered to the rotating arm within the channel.

[0011] Preferably, a handle for adjusting the length of the telescopic channel is fixedly mounted on the outer wall of the connection between the telescopic channel and the curtain. This handle provides the operator with a direct point of force application, allowing for convenient adjustment of the telescopic channel height through a gripping motion. Furthermore, the structural design fixed to the connection further enhances the stability of force transmission, ensuring the reliable connection between the curtain and the channel during height changes and preventing device wobbling or seal failure due to force misalignment.

[0012] Preferably, the curtain is a trumpet-shaped structure with a smaller diameter at the top and a larger diameter at the bottom, with the top closed and the bottom open. The top of the curtain has a long strip-shaped main suction hole, which connects the telescopic channel to the moxibustion space inside the curtain. The edge of the bottom opening of the curtain forms a flexible soft ring that can adapt to the undulations of the body parts.

[0013] The trumpet-shaped curtain, with its geometric design of a small-diameter sealed top and a large-diameter open bottom, creates a gradually expanding spatial distribution when covering the moxibustion area. This optimizes the path of hot airflow accumulation within the curtain while providing ample space for the patient. The elongated main suction port accelerates airflow by reducing the cross-sectional area, forcibly guiding the hot smoke within the moxibustion space towards the telescopic channel, significantly improving initial collection efficiency. The flexible ring, based on its adaptive deformation capability, closely conforms to the contours of the human body, dynamically sealing the gap between the bottom edge of the curtain and the skin. This ensures patient comfort while reducing the risk of smoke escaping from the bottom, achieving efficient directional flow of smoke within the enclosed space.

[0014] Preferably, the curtain has a double-layered structure with an inner and outer layer. Within the double layer, a suction channel extends along the generatrix of the curtain's sidewalls. A first suction hole communicating with the suction channel is located on the bottom sidewall of the curtain, and a second suction hole communicating with the suction channel is located on the top inner wall. The suction channel extending along the generatrix of the curtain's sidewalls within the double layer creates an auxiliary airflow path independent of the moxibustion space. The first suction hole on the bottom sidewall passively captures the moxa smoke escaping from the bottom edge of the curtain. This escaping smoke is directionally transported along the generatrix within the channel to the second suction hole on the top inner wall, where it is recirculated using the natural pressure difference between the top and bottom of the curtain, ultimately flowing into the main airflow channel. This dual-layered physical isolation recovery mechanism expands the range of moxa smoke collection, maintaining the curtain's overall sealing while specifically eliminating the edge escaping problem that is difficult to solve with traditional single-layer curtains, achieving a more comprehensive smoke collection effect.

[0015] Preferably, an annular heat-absorbing unit is attached to the inner side of the top of the telescopic channel. This heat-absorbing unit actively absorbs the energy of the hot flue gas flowing through the telescopic channel, forming a localized high-temperature region at the top of the channel. Based on the physical property that hot air is less dense than cold air, a significant temperature gradient is established inside the channel. This temperature difference drives the hot gas to rise continuously and the cold gas to sink naturally, forming a self-reinforcing vertical convection circulation, thereby improving the overall flue gas transport efficiency.

[0016] Preferably, the main structure of the smoke purification unit is a vertical tank with lockable casters at the bottom. The tank is equipped with a temperature sensing element, whose wires are electrically connected to a display screen on the tank surface. The vertically extending main structure provides stable space for the internal purification components while creating a compact vertical layout to optimize the equipment's footprint. The lockable casters at the bottom allow the device to quickly switch between mobile and stationary states. The display screen provides medical personnel with real-time temperature parameter feedback.

[0017] Preferably, a winding drum is provided at the top of the tank, and the connecting wires of the temperature sensing element are wound and stored in the winding drum. The integrated layout of the winding drum at the top of the tank ensures that the release and retrieval of the temperature sensing element wires follow an axial winding trajectory. This physical constraint prevents the wires from interfering with surrounding components during use, effectively eliminates the risk of tangling and knotting caused by disordered wire suspension, and reduces structural damage to the wires caused by repeated bending. This ensures the stability of temperature signal transmission while maintaining the neatness of the equipment's appearance.

[0018] Preferably, the top of the telescopic channel is connected to the rotating arm via a smoke exhaust pipe. The smoke exhaust pipe serves as a rigid connecting component between the top of the telescopic channel and the rotating arm, ensuring the physical continuity of the high-temperature moxa smoke airflow path at the connection point.

[0019] Preferably, a moxibustion waste ash bin is fixedly installed on the surface of the smoke-cleaning tank. This arrangement avoids the need for frequent handling of independent containers and reduces the occupation of limited space in the ward. Attached Figure Description

Detailed Implementation

[0027] The present invention will now be described in detail with reference to the accompanying drawings.

[0028] This embodiment relates to a device for collecting and purifying moxa smoke, such as... Figure 1 As shown, it includes a smoke-cleaning section 100, a collection section 200, and a rotating arm 300. The collection section 200 is used to collect the moxa smoke generated during moxibustion; the smoke-cleaning section 100 has a built-in suction pump and an air purification device; the suction pump is used to provide the collection section 200 with the suction force required to collect the moxa smoke; the air purification device is used to purify the moxa smoke sucked in by the suction pump; the rotating arm 300 is used to connect the smoke-cleaning section 100 and the collection section 200, and the hollow structure of the rotating arm 300 forms an airflow channel for transferring the moxa smoke collected by the collection section 200 to the smoke-cleaning section 100.

[0029] like Figure 1 , Figure 2 As shown, the smoke removal unit 100 is equipped with at least two collection units 200. Each collection unit 200 is movably connected to the smoke removal unit 100 via a corresponding rotating arm 300, and can be unfolded away from the smoke removal unit 100 or retracted towards the smoke removal unit 100 by rotating the rotating arm 300. The main structure of the smoke removal unit 100 is a vertical tank 110 with a certain height, and the bottom of the tank 110 is equipped with lockable casters 180. When the casters 180 are locked, the smoke removal unit 100 can be stably placed on the ward floor; when the casters 180 are unlocked, the smoke removal unit 100 can move flexibly within the ward. When the smoke removal unit 100 is moved to the aisle gap between adjacent beds, its different collection units 200 can be rotated by the corresponding rotating arm 300 and unfolded above different beds to simultaneously assist multiple patients in moxibustion treatment, improving efficiency.

[0030] like Figure 3 As shown, the collecting unit 200 includes a curtain 210 for covering the patient's moxibustion area. The curtain 210 is preferably a trumpet-shaped structure with a smaller top diameter and a larger bottom diameter, closed at the top and open at the bottom. The curtain 210 is made of a flexible material, allowing it to be finely adjusted to fit the patient's body curves. Preferably, the edge of the open bottom of the curtain 210 forms a flexible ring 211, which can deform to adapt to the undulations of the patient's body, thereby creating a relatively enclosed moxibustion space 216 between the curtain 210 and the patient's body. This enclosed space prevents moxa smoke from escaping into the external environment and causing pollution, while also fully utilizing the heat generated during moxibustion, preventing heat loss, and ensuring the therapeutic effect of moxibustion.

[0031] like Figure 3 As shown, the top of the curtain 210 of the collecting section 200 is equipped with a telescopic channel 220 for connecting the rotating arm 300 and the collecting section 200. This telescopic channel 220 allows air formed within the moxibustion space 216, carrying moxa smoke particles and carrying a certain amount of heat, to pass through, enter the rotating arm 300, and ultimately enter the smoke-cleaning section 100. The telescopic channel 220 has an adjustable length structure, preferably a telescopic duct made of flexible fabric, which has the advantages of flexible connection, large telescopic range, and lightweight. When the rotating arm 300 rotates to unfold the collecting section 200 above the bed, the telescopic channel 220 can adaptively adjust its length, allowing the curtain 210 to cover common moxibustion sites such as the navel, back, and limbs.

[0032] According to a preferred embodiment, the telescopic channel 220 may use aramid fiber as the base fabric layer, with polytetrafluoroethylene (PTFE) coated inside to prevent gas penetration and provide corrosion resistance. The base fabric layer is covered with composite aluminum foil for heat insulation and reflection, reducing the outer surface temperature and preventing burns from accidental contact by medical personnel. Several annular stainless steel rings are arranged on the exterior of the telescopic channel 220 along its axial extension direction, serving as a supporting frame to ensure the telescopic channel 220 maintains a vertical posture before and after extension. Furthermore, a handle 221 is provided on the outer wall of the connection between the telescopic channel 220 and the curtain 210. The handle 221 is designed for easy gripping by the operator, allowing direct adjustment of the axial length of the telescopic channel 220 through simple lifting or pulling movements. This enables quick and precise control of the curtain 210's coverage height, ensuring effective coverage of the moxibustion sites for different patients.

[0033] The main purpose of maintaining the vertical orientation of the telescopic channel 220 is to fully utilize the chimney effect and significantly improve the collection efficiency of moxa smoke. According to thermodynamic principles, the density of the hot air (carrying moxa smoke particles) formed within the moxibustion space 216 is lower than that of the external cold air, naturally generating an upward thermal pressure difference within the vertical channel. This thermal pressure difference, formed by temperature and height differences, drives the hot airflow to flow spontaneously and continuously upwards, passing through the telescopic channel 220 and rotating arm 300 into the smoke-cleaning section 100. This effect not only effectively enhances the suction force and reduces the energy consumption of the mechanical suction pump within the canister 110 of the smoke-cleaning section 100, but also conforms to the physical law of the natural upward movement of hot smoke, greatly reducing airflow resistance and avoiding problems such as decreased smoke flow velocity, particle deposition, and collection delays caused by unreasonable pipe routing, thus ensuring efficient and smooth directional transfer and collection of moxa smoke.

[0034] like Figure 4 As shown, the curtain 210 of the collecting section 200 has a main suction hole 212 at its closed top, which connects the telescopic channel 220 and the moxibustion space 216, thereby establishing a suction channel between the smoke-removing section 100 and the moxibustion space 216. The main suction hole 212 is preferably elongated. Compared to other shapes, elongated holes have a smaller flow cross-sectional area under the same conditions, allowing the airflow passing through them to achieve a higher flow velocity. This facilitates the acceleration of the flow of moxa smoke particles, thereby more quickly removing the moxa smoke from the moxibustion space 216 within the curtain 210. Preferably, the aspect ratio of the main suction hole 212 is 10–20:1, more preferably 15:1, to ensure good suction power.

[0035] According to a preferred embodiment, such as Figure 5 As shown, the curtain 210 can be configured as a double-layered structure with an inner and outer layer. Several suction channels 215 extending along the generatrix of the sidewall of the curtain 210 are pre-reserved in this interlayer. Each suction channel 215 has suction holes at both ends that penetrate the sidewall of the curtain 210: the first suction hole 213 is located near the bottom of the curtain 210, and the second suction hole 214 is located near the top of the curtain 210. The first suction hole 213 is evenly distributed around the side wall of the flexible ring 211 at the bottom of the curtain 210, located outside the moxibustion space 216, and is used to absorb the moxa smoke that may escape from the gap between the ring 211 and the human body. The second suction hole 214 is opened on the inner wall of the curtain 210, surrounding the top of the curtain 210, located inside the moxibustion space 216 and adjacent to the main suction hole 212. The suction force of the main suction hole 212 is used to allow the moxa smoke that has escaped and been absorbed by the first suction hole 213 to enter the moxibustion space 216 through the suction channel 215 in the interlayer, and finally be sent to the smoke purification section 100 for purification.

[0036] like Figure 3As shown, the top opening of the telescopic channel 220 is closed by an arc-shaped dome. A smoke exhaust pipe 230 is disposed outside this arc-shaped dome, connecting the telescopic channel 220 to the rotating arm 300. The cavity of the smoke exhaust pipe 230 is in fluid communication with the inner cavity of the rotating arm 300. A heat-absorbing unit 222, such as a ring-shaped copper foil heat-absorbing tape or an aluminum alloy radiant plate, is attached to the inner side of the arc-shaped dome of the telescopic channel 220. This heat-absorbing unit 222 has good heat absorption performance, absorbing the heat of the gas flowing through the telescopic channel 220 during moxibustion smoke extraction, thus increasing its own temperature. The configuration of the heat-absorbing unit 222 makes the temperature in the upper region of the telescopic channel 220 significantly higher than that in the lower region. According to thermodynamic principles, increased temperature leads to decreased air density, causing the high-temperature gas to rise in the upper part of the channel; while the lower-temperature, higher-density air flows downwards. This gas convection driven by temperature difference is enhanced within the vertically extending telescopic channel 220, forming a chimney-like thermo-pressure driven effect, which significantly enhances the chimney effect within the telescopic channel 220, thereby increasing the inhalation rate of the moxa smoke.

[0037] like Figure 1 , Figure 2 As shown, the canister 110 of the smoke removal section 100 is equipped with a plurality of temperature measuring elements 120 for detecting the temperature of the moxibustion space 216 formed by each collection section 200. The number of temperature measuring elements 120 is the same as the number of collection sections 200, so that the temperature of the moxibustion space 216 corresponding to each collection section 200 can be obtained by an independent temperature measuring element 120. According to a preferred embodiment, these temperature measuring elements 120 are electrically connected to a display screen 140 on the surface of the canister 110, so that medical personnel can directly read the temperature value corresponding to each temperature measuring element 120 through the display screen 140.

[0038] like Figure 1 As shown, the top of the canister 110 is also equipped with a winding drum 130 for storing the temperature measuring element 120. The temperature measuring element 120 includes interconnected temperature probes and connecting wires: the temperature probes can be placed inside the moxibustion space 216 to measure the temperature, while the connecting wires are stored in the winding drum 130. Medical staff can adaptively release the required length of connecting wire from the winding drum 130 according to the distance between the smoke-removing section 100 and the patient bed; after the measurement is completed, the connecting wires can be rewound onto the winding drum 130, achieving orderly storage of the temperature measuring element 120.

[0039] like Figure 1 , Figure 2As shown, the surface of the smoke purification unit 100 tank 110 is equipped with a moxibustion waste ash bin 160 for temporary storage of waste ash generated after moxibustion treatment. The surface of the tank 110 also has a control panel 150 and a power interface 170. The control panel 150 is electrically connected to the suction pump and air purification device inside the tank 110, allowing medical personnel to start and stop the corresponding equipment as needed. The power interface 170 provides power to the equipment inside the tank 110. The air purified by the air purification device is finally discharged into the surrounding environment through the exhaust port 190 on the back of the tank 110.
