[0002] Cupping, as a long - spread traditional Chinese medicine treatment method, generates negative pressure by burning substances, enabling the cup to adsorb on the human skin surface to promote blood circulation, relieve muscle tension and pain. Traditional cupping methods usually use alcohol cotton balls or other flammable substances as ignition materials.

DETAILED DESCRIPTION

[0026] In order to facilitate the understanding of the present application, the present application will be described more fully below with reference to the relevant drawings. The preferred embodiments of the present application are given in the drawings. However, the present application can be implemented in many different forms and is not limited to the embodiments described herein. On the contrary, the purpose of providing these embodiments is to make the disclosure of the present application more thoroughly and comprehensively understood.

When an element is considered to be "connected to" another element, it can be directly connected to the other element or there may be an intermediate element at the same time. The terms "vertical", "horizontal", "left", "right", "top", "bottom", "bottom end", "top end" and similar expressions used herein are only for illustrative purposes and do not represent the only implementation.

[0028] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by those of ordinary skill in the technical field to which this application belongs. The terms used herein in the specification of this application are only for the purpose of describing specific implementations and are not intended to limit this application. The term "and / or" used herein includes any and all combinations of one or more of the related listed items.

[0029] Please refer to Figures 1 to 5 , in a specific implementation of this application, a fog flame instantaneous combustion safety igniter for cupping therapy includes a holding part 100, a fuel supply part 200 is arranged on the holding part 100, and a combustion part 300 is arranged at one end of the holding part 100.

[0030] The fuel supply part 200 includes a fuel storage member 210 and a fuel atomization assembly 220 communicated with the fuel storage member 210. The fuel atomization assembly 220 is arranged at the end of the holding part 100; the combustion part 300 includes an interception and flame retardant assembly. The interception and flame retardant assembly is located at the same end as the fuel atomization assembly 220, covers the outside of the fuel atomization assembly 220, and forms a diffusion space 400 with the end of the holding part 100. The ignition assembly 330 includes a spark generating member 331, and the spark generating member 331 is arranged close to the outside of the interception and flame retardant assembly.

[0031] Among them, the holding part 100 is the handle part of the igniter, which is convenient for users to hold and operate; a fuel supply part 200 is arranged on the holding part 100, and the fuel supply part 200 is responsible for storing and providing the fuel required for combustion. The fuel supply part 200 includes the fuel storage part 210 and a fuel atomization assembly 220 communicated with the fuel storage part 210. The fuel storage part 210 is used for storing liquid fuel. The fuel supply part 200 may further include a fuel supply pump that provides power for conveying the liquid fuel in the fuel storage part 210. By starting the fuel supply pump, the liquid fuel in the fuel storage part 210 can be conveyed to the fuel atomization assembly 220; the fuel atomization assembly 220 is located at one end of the holding part 100 and converts the liquid fuel in the fuel storage part 210 into fine mist particles, namely small droplets. The combustion part 300 is detachably arranged at one end of the holding part 100. The combustion part 300 includes an interception and flame retardant assembly, which is mainly used for intercepting the small droplets atomized by the fuel atomization assembly 220 to prevent the small droplets from diffusing outward in a liquid form, and at the same time can prevent the flame from burning inward when the igniter is lit. The interception and flame retardant assembly covers the outside of the fuel atomization assembly 220 and forms a diffusion space 400 with the end of the holding part 100. The diffusion space 400 expands the diffusion area of the liquid fuel, enabling the liquid fuel to uniformly enter the interception and flame retardant assembly. The ignition assembly 330 includes a spark generating part 331, and the spark generating part 331 is arranged close to the outside of the interception and flame retardant assembly. The spark generating part 331 is mainly used for generating a spark outside the interception and flame retardant assembly, so as to achieve the purpose of igniting the igniter.

[0032] It should be noted that the liquid fuel in the fuel storage part 210 is atomized into fine small droplets through the fuel atomization assembly 220. When the small droplets fill the diffusion space 400, the small droplets diffuse into the interception and flame retardant assembly until the small droplets reach saturation in the interception and flame retardant assembly. Due to the volatility of the small droplets, the small droplets volatilize in the interception and flame retardant assembly, the small droplets are vaporized into combustible gas, and pass through the interception and flame retardant assembly to form a combustible gas layer outside the interception and flame retardant assembly. When the combustible gas is ignited, with the combustion of the combustible gas, the intercepted liquid fuel small droplets in the interception and flame retardant assembly are still continuously volatilized, supplying combustible gas to the outer layer of the interception and flame retardant assembly, thereby ensuring the continuity of the flame.

[0033] In a specific working process, for example, in the process of cupping, first, the cup is prepared, and then the user holds the gripping portion 100 and can apply pressure to the fuel storage component 210 through external force, so that the fuel (such as alcohol) in the fuel storage component 210 flows to the fuel atomization component 220, and the fuel atomization component 220 atomizes the liquid fuel from the fuel storage component 210 into fine droplets, which quickly fill the diffusion space 400 and diffuse into the interception flame retardant component until the droplets reach saturation in the interception flame retardant component. Due to the volatility of the liquid fuel, the droplets evaporate and escape from the outside of the interception flame retardant component, thereby forming a flame retardant on the outside of the interception flame retardant component. A combustible gas layer is formed. After the combustible gas is ignited by the spark generating element 331, a uniform and vigorous blue flame can be seen formed at the front end of the igniter, which makes the combustible gas burn fully. The user holds the cupping jar with one hand, and tilts the open end of the cupping jar downward by 15 to 45 degrees, and tilts the flame end of the igniter upward by 15 to 45 degrees. Maintaining this angle, the igniter is inserted into the cupping jar, staying for 1 to 3 seconds, and then quickly and smoothly removes the igniter from the cupping jar, and immediately fits the open end of the cupping jar tightly to the skin. As the temperature in the cupping jar drops, the volume of the air in the cupping jar shrinks, thereby generating a negative pressure effect, causing the cup body to be adsorbed on the skin.

[0034] The use of the above-mentioned igniter has at least the following beneficial effects: the present application adopts a diffusion space 400 formed by the interception flame retardant component and the end of the holding portion 100, so that the small droplets atomized by the fuel atomization component 220 can quickly fill the diffusion space 400, and the diffusion space 400 expands the penetration area of ​​the liquid fuel, so that the small droplets of liquid fuel can evenly enter the interception flame retardant component, and temporarily intercept the small droplets in the interception flame retardant component to prevent the small droplets from diffusing outward in liquid form. The interception flame retardant component can effectively intercept the small droplets, and will not hinder the flammable gas generated after the volatilization of the small droplets from escaping to the outside, so that the volatilized combustible gas surrounds the outside of the interception flame retardant component, ignites the combustible gas, and the combustible gas is fully burned to form a uniform and vigorous blue flame at the front end of the igniter, thereby avoiding the generation of unburned residues or carbon deposits inside the fire cup due to incomplete combustion of the liquid fuel, and blackening the fire cup.

[0035] To further effectively slow down or intercept the diffusion of small droplets to the outside, the interception and flame retardant component includes an interception layer 310. The interception layer 310 includes a first mesh cover 311, a second mesh cover 312 and an interception member 313. The first mesh cover 311 is arranged at one end of the holding part 100 where the fuel atomization component 220 is located, and the open end is connected to the holding part 100. A diffusion space 400 is formed between the first mesh cover 311 and the end of the holding part 100. The second mesh cover 312 covers the outside of the first mesh cover 311, and the interception member 313 is filled between the first mesh cover 311 and the second mesh cover 312. Among them, the interception layer 310 is mainly used to slow down or intercept the movement of small droplets to the outside. A diffusion space 400 is formed between the first mesh cover 311 and the end of the holding part 100, effectively preventing the interception member 313 from directly contacting the fuel atomization component 220, and can prevent the interception member 313 from blocking the atomization nozzle. The interception member 313 mainly fully absorbs the small droplets emitted from the diffusion space 400, so that the small droplets are evenly intercepted between the first mesh cover 311 and the second mesh cover 312, slowing down their movement speed to the outside, and enabling the small droplets to be fully vaporized into combustible gas in the interception member 313. The combustible gas passes through the second mesh cover 312, forming combustible gas around the outside of the second mesh cover 312, igniting the combustible gas, and forming a uniform and vigorous blue flame outside the second mesh cover 312.

[0036] To effectively intercept the small droplets diffused from the spray structure, the interception member 313 is any one of flame retardant cotton or hemp fiber. Flame retardant cotton or hemp fiber can achieve the purpose of intercepting small droplets by slowing down the passing speed of small droplets, and prevent the diffusion of small droplets.

[0037] To further effectively intercept the diffusion speed of small droplets, the filling density of the interception member 313 is 2 g / cm 3 to 6 g / cm 3 . Specifically, the filling density directly affects the interception efficiency of the interception member 313 for small droplets. According to the difference of the interception member 313 and the limitation of the intercepted amount of small droplets, the filling density of the interception member 313 is preferably 2 g / cm 3 to 6 g / cm 3 . If the filling density is too small, it may cause the diffusion of small droplets and the interception effect cannot be achieved. If the filling density is too high, it will lead to a reduction in the volatilization efficiency of small droplets. Therefore, an appropriate filling density can effectively intercept small droplets.

[0038] In practical applications, the flame burns outside the second wire mesh cover 312. However, when the combustion time is too long, the high temperature may gradually spread to the surroundings and eventually touch the intercepting member 313, causing thermal damage or burning to it, thus affecting the intercepting effect of the intercepting member 313. To further prevent the flame from directly contacting the intercepting member 313, the intercepting and flame-retardant assembly further includes a flame-retardant layer 320. The flame-retardant layer 320 includes a third wire mesh cover 321, a fourth wire mesh cover 322, and a flame-retardant member 323. The third wire mesh cover 321 is disposed outside the second wire mesh cover 312, the fourth wire mesh cover 322 is disposed outside the third wire mesh cover 321, and the flame-retardant member 323 is filled between the third wire mesh cover 321 and the fourth wire mesh cover 322. Among them, the flame-retardant layer 320 is mainly used to reduce the conduction of the flame to the inside, ensuring that even long-term combustion will not cause damage to the internal components; the flame-retardant member 323 is a flame-retardant material with excellent heat insulation performance and high-temperature resistance characteristics, and can maintain a stable state under high-temperature conditions to prevent the flame from spreading inward. The third wire mesh cover 321 and the fourth wire mesh cover 322 are mainly used to support the flame-retardant member 323 and can also maintain the gas flow; thus, the flame-retardant layer 320 effectively reduces the temperature of the internal structure, thereby protecting the intercepting member 313 from damage.

[0039] To further enhance the flame-retardant efficiency, the flame-retardant member 323 is any one of mineral wool, ceramic fiber, or flame-retardant cotton. They are all loose cotton-like materials, convenient for filling, not only have good fireproof performance but also maintain a certain degree of air permeability, and are good flame-retardant materials. The filling density of the flame-retardant member 323 is preferably 0.5 g / cm 3 to 2 g / cm 3 .

[0040] In a specific application, the ideal combustion condition is that all the small droplets ejected by the fuel atomization assembly 220 are intercepted by the interception member 313, and all the small droplets in the interception member 313 are finally vaporized into combustible gas. When the combustible gas is ignited, although the supply of combustible gas volatilized from small droplets is achieved in the above structure, if the combustion time is too long, it may occur that the small droplets are not completely vaporized, resulting in some small droplets diffusing outward and causing liquid-phase combustion. Therefore, in order to further ensure that all the gas used in the combustion process is combustible gas and avoid unvaporized small droplets participating in combustion, a gas phase space 500 is formed between the second mesh cover 312 and the third mesh cover 321. Among them, a certain distance is maintained between the second mesh cover 312 and the third mesh cover 321 to form the gas phase space 500, which serves as a buffer area for the vaporization of small droplets, helps to further reduce the risk of liquid-phase combustion, and provides additional time and space for the small droplets that have not been completely vaporized to complete the vaporization process. At the same time, the function of the gas phase space 500 is to temporarily store the vaporized combustible gas, so that these gases can be released outward after being fully prepared in a safe environment. When the igniter is ignited, since the outside of the fourth mesh cover 322 is surrounded by flames and the inside is relatively cold, this temperature difference generates a chimney effect (i.e., the principle of hot air rising), which promotes the continuous delivery of the combustible gas in the gas phase space 500 to the outside. At the same time, the small droplets that have not been completely vaporized in the interception member 313 continue to vaporize under the action of temperature, continuously replenishing fresh combustible gas for the gas phase space 500 to ensure a stable and sufficient fuel supply for the flame. Finally, a uniform, vigorous and stable blue flame is formed outside the fourth mesh cover 322. By setting the gas phase space 500, the potential liquid-phase combustion problem is effectively transformed into a more sufficient gas-phase combustion process. In addition, even if the small droplets in the interception member 313 are oversaturated, it will not affect the normal volatilization of the fuel and the replenishment of the gas phase space 500, thereby improving the overall safety and combustion efficiency of the igniter.

[0041] To further ensure the balance between the flame retardant effect and gas permeability, the distance between the third mesh cover 321 and the fourth mesh cover 322 is 1 mm to 3 mm. Among them, the flame retardant layer 320, on the one hand, needs to have effective flame retardant performance to prevent the spread of flames; on the other hand, it needs to allow the combustible gas to pass through moderately. Therefore, the distance between the third mesh cover 321 and the fourth mesh cover 322 determines the filling amount of the flame retardant member 323. If the distance is too small, it may lead to insufficient filling of the flame retardant material and weaken its flame retardant effect; conversely, if the distance is too large, although the amount of flame retardant material can be increased, it may hinder the effective penetration of gas and affect the combustion efficiency. Therefore, the preferred distance range of 1 mm to 3 mm in this application is the best balance point found between the flame retardant performance and gas permeability, which can not only effectively prevent the spread of flames but also ensure the gas supply required for combustion, thus ensuring the stability of the flame.

[0042] To ensure that small droplets can be fully atomized and maintain a stable combustion efficiency, and to further optimize the diffusion and gasification processes of the liquid fuel, the volume ratio of the filling space of the interception member 313 to the volume of the gas phase space 500 is 1:(1 to 4). Among them, the interception member 313 serves as a temporary storage area for small droplets. In this area, small droplets gather to reach a saturated state. Specifically, the role of the interception member 313 is to provide an appropriate environment for small droplets to stay for enough time to complete the preliminary gasification process. Small droplets gradually gasify into combustible gas, and the concentration of combustible gas in the gas phase space 500 gradually increases. At this time, if the gasification space is too small, it may cause small droplets not to have enough space and time to complete gasification. When the combustible gas is ignited, affected by the chimney effect, the incompletely gasified small droplets directly participate in combustion, reducing the combustion efficiency and possibly causing problems of unstable combustion. On the contrary, if the gas phase space 500 is too large, although it provides sufficient space for small droplets to gasify, the overly large gas phase space 500 will dilute the combustible gas generated by the gasification of small droplets, reducing its density. The low-density combustible gas means that the energy content per unit volume decreases, which will also have a negative impact on the combustion efficiency. Therefore, it is crucial to select an appropriate ratio between the interception member 313 and the gas phase space 500. The preferred ratio of the interception member 313 to the gas phase space 500 in this application is between 1:(1 to 4), which not only ensures that small droplets have enough time and space to complete gasification but also ensures that the generated combustible gas remains within an ideal density range. As the combustible gas burns, small droplets are continuously gasified, and the combustible gas continuously replenishes the gas phase space 500 to support an efficient and stable combustion process, thereby effectively controlling the diffusion and gasification processes of the liquid fuel and further improving the combustion efficiency. It should be noted that the gas phase space 500 does not provide a space for completely gasifying all small droplets, but rather a gas phase space 500 that provides enough combustible gas gasified from small droplets to supply the combustion of the igniter.

[0043] To further achieve the purpose of automatic ignition, a fire ignition switch 332 is provided on the holding part 100, and the fire ignition switch 332 is electrically connected to the spark generating member 331. Among them, the spark generating member 331 is mainly used to ignite the combustible gas outside the fourth mesh cover 322. The fire ignition switch 332 is electrically connected to the spark generating member 331. When the ignition switch is pressed, the spark generating member 331 can generate a spark. The ignition generating component in this application is any one of a piezoelectric ceramic igniter or a microelectromechanical system (MEMS) igniter, which can form an electric spark outside the fourth mesh cover 322, and the electric spark can ignite the combustible gas surrounding the outside of the fourth mesh cover 322, thereby realizing the ignition function.

[0044] In a specific embodiment, the fuel atomization assembly 220 is any one of a jet atomizer or an ultrasonic atomizer. Among them, the fuel atomization assembly 220 mainly atomizes the fuel in the fuel storage member 210 to turn it into fine droplets. Among them, the jet atomizer breaks the liquid fuel into fine particles through pressure to form a mist-like jet for atomization; the ultrasonic atomizer uses the physical action of ultrasonic waves to disperse the liquid fuel into tiny droplets, thereby forming an atomization effect. In this application, the ultrasonic atomizer is preferably used.

[0045] To facilitate the replacement of the fuel storage member 210 or the addition of fuel, the holding portion 100 is detachably connected to the fuel storage member 210, and a detachable structure matching the fuel storage member 210 is provided on the holding portion 100. For example, corresponding spiral structures are provided on the holding portion 100 and the fuel storage member 210 respectively. By rotating, the fuel storage member 210 can be tightly installed on the holding portion 100, and by rotating in the reverse direction, the fuel storage member 210 can be conveniently removed; or a snap connection structure, or a slide rail and slot matching structure, etc., which facilitates the replacement of the fuel storage member 210, thereby improving the user's convenience and increasing the practicality of the product.

[0046] To facilitate fire extinguishing, a detachable fire extinguishing cap is also provided at the end of the holding portion 100, and the fire extinguishing cap can be hermetically covered on the surface of the fourth mesh cover 322. For safe fire extinguishing, a groove is provided at one end of the holding portion 100, and a corresponding protrusion is provided on the fire extinguishing cap. Through a simple snap action, the fire extinguishing cap can be hermetically covered on the surface of the fourth mesh cover 322, isolating the fourth mesh cover 322 from the air and quickly extinguishing the flame. When the igniter is not in use, it covers the ignition port, thereby preventing the igniter from accidentally igniting or dust from entering.

[0047] To further explore the full combustion efficiency of the igniter, the visual evaluation method is adopted to observe the flame shape and carbon residue condition:

[0048] Preparation: The fire cupping jar is a spherical fire cupping jar made of glass purchased on the market, with an inner diameter of the jar mouth of 5.5 cm, an outer diameter of the jar mouth of 7 cm, and a jar height of 9.7 cm; the liquid fuel is alcohol with a concentration of 95%.

[0049] The evaluation criteria for the residue on the inner wall of the fire cupping jar are as follows:

[0050] No residue: The inner wall of the fire cupping jar remains the original color without discoloration.

[0051] Slight residue: There is a small amount of residue in the fire cupping jar, and the inner wall of the fire cupping jar shows a slightly yellowish tone.

[0052] Moderate residue: There is obvious residue in the fire cupping jar, and the inner wall of the fire cupping jar shows a dark yellow or brown color.

[0053] Severe residue: There is a large amount of residue in the cupping jar, and the inner wall of the cupping jar shows black, and only weak light may pass through or it is completely opaque.

[0055] Prepare a clean cupping jar. After lighting it, the user should hold the cupping jar with one hand and tilt the open end of the cupping jar downward at an angle of 45 degrees. With the other hand, hold the electronic spray ignition device and tilt the flame end of the igniter upward at an angle of 45 degrees. Keeping this angle, insert the flame end of the portable cupping ignition device into the cupping jar, stay in the cupping jar for 2 seconds, quickly and smoothly take out the igniter from the cupping jar, and immediately quickly buckle the open end of the cupping jar on the detection table until the cupping jar cools down to room temperature. After repeating the experiment 60 times, observe the flame color (such as Figure 3 ) and the residue on the inner wall of the cupping jar (as shown in Table 1).

Keeping this angle, insert the flame end of the portable cupping ignition device into the cupping jar, stay in the cupping jar for 2 seconds, quickly and smoothly take out the igniter from the cupping jar, and immediately quickly buckle the open end of the cupping jar on the detection table until the cupping jar cools down to room temperature. After repeating the experiment 60 times, observe the flame color (such as Figure 4 ) and the residue on the inner wall of the cupping jar (as shown in Table 1).

[0060]

[0061] As can be seen from Table 1, in Comparative Example 1, using the ignition method in the background technology, it is observed that when using the electronic spray ignition device, after ignition, the flame is a yellow flame. After 60 simulated cupping experiments, there is obvious residue in the cupping jar of Comparative Example 1, and the inner wall of the cupping jar shows dark yellow or brown, which is medium residue; in the present application, when the filling density of the intercepting member 313 of the igniter is 2 g / cm 3 to 6 g / cm 3When the volume ratio of the volume of the filling space of the intercepting member 313 to the volume of the gas phase space 500 is 1:(1 to 4), although a blue flame can be seen, there are occasionally a small amount of yellow flames in the blue flame. And after 60 simulated cupping experiments, there is a small amount of residue in the cupping jar, and the inner wall of the cupping jar shows a slightly yellowish tone, which is a slight residue. This is because some small droplets directly participate in the combustion during the ignition process of the igniter, resulting in incomplete combustion, and residues are formed on the inner wall of the cupping jar after the cupping jar cools down.

[0062] Example 2: Using the instantaneously burning safety fog flame igniter for cupping in the present invention as Figure 2 the instantaneously burning safety fog flame igniter for cupping

[0063] The parameters of the igniter are: the filling density of the intercepting member 313 is 4 g / cm 3 , the volume ratio of the volume of the filling space of the intercepting member 313 to the volume of the gas phase space 500 is 1:1, the distance between the third mesh cover 321 and the fourth mesh cover 322 is shown in Table 2, the flame retardant member 323 is selected as mineral wool, and the filling density is shown in Table 2. The experimental steps are as follows:

[0064] Prepare a clean cupping jar. Use the instantaneously burning safety fog flame igniter for cupping with a flame retardant layer 320 added. After ignition, the user should hold the cupping jar with one hand and tilt the open end of the cupping jar downward at an angle of 45 degrees, and hold the instantaneously burning safety fog flame igniter for cupping with the other hand and tilt the flame end of the igniter upward at an angle of 45 degrees. Keeping this angle, insert the flame end of the portable cupping igniter into the cupping jar, stay in the cupping jar for 2 seconds, quickly and steadily take out the igniter from the cupping jar, and immediately quickly buckle the open end of the cupping jar on the detection table until the cupping jar cools down to room temperature. After repeating the experiment 60 times, observe the flame color (such as Figure 5 ) and the residue on the inner wall of the cupping jar (shown in Table 2).

[0065] Table 2 Observation of flame shape and residue degree after 60 tests

[0066]

[0067] As can be seen from Table 2, Example 2 is the instantaneously burning safety fog flame igniter for cupping with a flame retardant layer 320 added. After ignition, the flame is a blue flame, and after 60 simulated cupping experiments, the inner wall of the cupping jar remains the original color without discoloration, which is a non-residue state.

[0068] Example 3: Explore the long-term stability of the igniter

[0069] Keep the experimental steps of Experimental Example 1 unchanged. The parameters of the igniter are: the filling density of the intercepting member 313 is 2 g / cm 3 , the volume ratio of the volume of the filling space of the intercepting member 313 to the volume of the gas phase space 500 is 1:1. After repeating the experiment 200 times, observe the residue on the inner wall of the cupping jar.

[0070] Example 4

[0071] Keep the experimental steps of Experimental Example 2 unchanged. The packing density of the interception member 313 is 2 g / cm 3 , the volume ratio of the filling space of the interception member 313 to the volume of the gas phase space 500 is 1:1, the distance between the third wire mesh cover 321 and the fourth wire mesh cover 322 is 1 mm, and the flame retardant member 323 is made of mineral wool with a packing density of 0.5 g / cm 3 .

[0072] Table 3 Residue observed on the inner wall of the cupping jar after 200 tests

[0073] Residue on the inner wall of the cupping jar Example 3 Slight Example 4 None

[0074] As shown in Table 3, Experimental Example 3 and Experimental Example 4 are to further prove the long-term stability of the igniter of the present application. After repeating the experiment 200 times, the residue on the inner wall of the cupping jar in Example 3 is mild. Compared with Experimental Example 2, there is a small amount of residue in the cupping jar, and the inner wall of the cupping jar shows a slightly yellowish tone, and the color is darker than that in Experimental Example 2, but it has not reached the degree of moderate residue. This is because the increase in the number of experiments leads to an increase in the residue, but the residue is greatly reduced compared with the comparative example. In Experimental Example 4, after 200 experiments, the inner wall of the cupping jar remains the original color without discoloration, showing a residue-free state. This shows that the combustion effect of Experimental Example 4 is better, and the igniter is completely in gas-phase combustion during the combustion process and burns fully.
