[0002] Plasma acupuncture is a new acupuncture technology based on traditional acupuncture therapy and combined with modern technology. Traditional acupuncture therapy adjusts the balance of qi and blood in the human body by applying acupuncture to specific acupoints, achieving the purpose of treating diseases. Plasma acupuncture uses a biological electric phenomenon generated by plasma technology during acupuncture to enhance the therapeutic effect of acupuncture. Plasma acupuncture equipment mainly consists of an acupuncture needle and a plasma generating device. During acupuncture, the plasma generated by the needle can form a small electric field at the acupuncture site, which can affect the excitability of local nerves and muscles, promote blood circulation, and help relieve pain and promote tissue repair.

[0016] Wherein N1 < N2 < N3.

[0017] In some embodiments, the switching member comprises a body portion and a connecting portion protruding from the body portion, the switching member being configured to be driven by the driving member to move towards the plasma generating assembly so as to make the connecting portion fit the piezoelectric ceramic.

[0047] The realization of the objective, functional features and advantages of the present invention will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0048] 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 a part of the embodiments of the present invention, and not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of the present invention.

[0049] Plasma is a gaseous substance composed of positive and negative ions produced by the ionization of atoms and atomic groups. It is macroscopically electrically neutral and is the fourth state of matter in nature, in addition to solids, liquids, and gases. When energetic or charged particles in plasma act on nerves or cells in tissues, they can cause the charged particles in the nerves or cells to move under the influence of an electric field. This combination of physical pressure and charge movement achieves the effect of needling acupoints in acupuncture.

[0050] In view of this, please refer to Figures 1 to 5This invention provides a handheld acupuncture device 100, which includes a housing 110, a plasma generating assembly 120, a firing assembly 130, and a conducting assembly 140. The housing 110 defines a receiving cavity 111, within which the plasma generating assembly 120 is disposed. The plasma generating assembly 120 includes a plurality of piezoelectric ceramics configured to generate an electric current upon pressure to form plasma. The firing assembly 130 is also disposed within the receiving cavity 111 and configured to fire the piezoelectric ceramics upon being driven, thereby generating an electric current in the piezoelectric ceramics and ionizing the air to form plasma. The conducting assembly 140 is disposed within the receiving cavity 111 and configured to collect and discharge the plasma generated by the piezoelectric ceramics for acupuncture treatment. The firing assembly 130 includes a driving member 131 and a switching member 132. The switching member 132 is configured to be able to cooperate with any number of piezoelectric ceramics by switching its position. The driving member 131 is used to drive the switching member 132 to fire the piezoelectric ceramics that cooperate with the switching member 132.

[0051] Specifically, the housing 110 provides support and protection for the plasma generating assembly 120, the firing assembly 130, and the conduction assembly 140, while also integrating these components into a single unit, improving the overall integrity of the acupuncture device. In some embodiments, the housing 110 can be a hollow elongated cylinder, a hollow cuboid, etc., and can be manufactured using a one-piece molding method or a segmented manufacturing and assembly method. When the piezoelectric ceramics in the plasma generating assembly 120 are driven by the firing assembly 130, they generate an electric current, which ionizes the air to form plasma. The driving component 131 can be a motor, an electromagnet, or other type of driving mechanism. By controlling the movement of the driving component 131, different positions of the switching component 132 can be switched, thereby achieving the firing of different numbers of piezoelectric ceramics. The conduction assembly 140 is responsible for collecting and exporting the plasma, ensuring that the plasma can effectively act on the affected area and guaranteeing the stable conduct of acupuncture or treatment.

[0052] It is understood that, in some embodiments, by providing the switching element 132 and multiple piezoelectric ceramics, the switching element 132 can cooperate with any number of piezoelectric ceramics, thereby enabling the acupuncture device to output plasmas of different energy densities as needed. Specifically, the design of the switching element 132 allows for precise control of the plasma output energy density, thereby achieving optimal stimulation and therapeutic effects during treatment.

[0053] It should be noted that this application uses piezoelectric ceramics with small size and high release voltage to generate plasma, eliminating the need for large gas cylinders (typically used to load inert gases or pre-generated plasma to ensure plasma supply during treatment or acupuncture) and bulky batteries (plasma generators in related technologies typically require high-voltage batteries, which need to generate thousands or even tens of thousands of volts, resulting in very large battery sizes). In other words, the acupuncture device of this application does not require a large battery for plasma generation, thus effectively reducing the size of the acupuncture device and improving portability. Furthermore, since no additional large gas cylinder is needed, the size and weight of the acupuncture device are effectively controlled, further improving portability.

[0054] Based on this, the acupuncture device of this application can not only adjust the number of piezoelectric ceramics and switching elements 132 to change the energy density of plasma output according to different symptoms or the tolerance levels of different patients, thus adapting to diverse treatment needs, but also effectively reduce the size and weight of the acupuncture device, improving portability. This makes the acupuncture device of this application more widely applicable and meets the needs of more users.

[0055] Please see Figures 3 to 5 In some embodiments, the plasma generating assembly 120 further includes a positioning member 124 disposed within the receiving cavity 111. The positioning member 124 includes a clearance portion 1241 and a working portion 1242. A piezoelectric ceramic is mounted on the working portion 1242. A switching member 132 is configured to switch between the clearance portion 1241 and the working portion 1242, thereby disconnecting or connecting the plasma generating assembly 120 to the firing assembly 130. Specifically, the positioning member 124 is designed so that the switching member 132 can switch between the clearance portion 1241 and the working portion 1242. When the switching member 132 is in the clearance portion 1241, the plasma generating assembly 120 is disconnected from the firing assembly 130, meaning the piezoelectric ceramic does not engage with the switching member 132, and the piezoelectric ceramic will not be fired. When the switching element 132 is switched to the working part 1242, the plasma generating component 120 is connected to the firing component 130. That is, the piezoelectric ceramic cooperates with the switching element 132, and the firing component 130 can fire the piezoelectric ceramic to generate current and ionize the air to form plasma.

[0056] Understandably, in some embodiments, the positioning element 124 enables the plasma generating component 120 and the firing component 130 to be disconnected or connected. Thus, when the acupuncture device is not in use, the plasma generating component 120 and the firing component 130 can be disconnected to avoid unnecessary energy consumption. When in use, the position of the switching element 132 is adjusted to connect the plasma generating component 120 and the firing component 130, thereby achieving the firing of the piezoelectric ceramic. The positioning element 124 includes a clearance portion 1241 and a working portion 1242. The clearance portion 1241 prevents the plasma generating component 120 from contacting the firing component 130 in the non-working state, while the working portion 1242 ensures normal contact between the two in the working state. This improves the flexibility and safety of the acupuncture device, and also saves energy and extends its service life when not in use. In other words, by switching the switching element 132 between the avoidance part 1241 and the working part 1242, this application realizes flexible control of the acupuncture device in different states, thereby improving the practicality and safety of the acupuncture device.

[0057] Please see Figure 4 and Figure 5 In some embodiments, the number of piezoelectric ceramics can be any value, and the specific number can be set according to the specific application scenario of the acupuncture device. For ease of description, in some embodiments, the number of piezoelectric ceramics is three, namely a first piezoelectric ceramic 121, a second piezoelectric ceramic 122, and a third piezoelectric ceramic 123. The size and discharge specifications of each piezoelectric ceramic can be the same or different. Thus, the firing assembly 130 has multiple firing states, defined as a first firing state, a second firing state, and a third firing state:

[0058] First firing state: When the firing assembly 130 is in the first firing state, the firing assembly 130 only fires the first piezoelectric ceramic 121. At this time, the plasma discharged by the conduction assembly 140 has an energy density N1.

[0059] Second firing state: When the firing assembly 130 is in the second firing state, the firing assembly 130 can fire the first piezoelectric ceramic 121 and the second piezoelectric ceramic 122 at the same time, or the firing assembly 130 can be used to fire the second piezoelectric ceramic 122. At this time, the plasma discharged by the conduction assembly 140 has an energy density N2.

[0060] Third firing state: When the firing assembly 130 is in the third firing state, the firing assembly 130 can fire the first piezoelectric ceramic 121, the second piezoelectric ceramic 122 and the third piezoelectric ceramic 123, or the firing assembly 130 can fire the third piezoelectric ceramic 123. At this time, the plasma discharged by the conduction assembly 140 has an energy density N3.

[0061] Among them, the energy density N1 < N2 < N3. That is, as the firing state of the firing component 130 varies, the energy density of the plasma generated by the plasma generating component 120 also changes accordingly, so that the output energy density of the plasma can be adjusted according to different treatment requirements.

[0062] Specifically, when the firing component 130 only fires the first piezoelectric ceramic 121, the energy density of the plasma is the lowest, so the acupuncture device can be used for mild treatment or treatment of sensitive parts. When the firing component 130 is used to fire the first piezoelectric ceramic 121 and the second piezoelectric ceramic 122, the energy density of the plasma is moderate, so the acupuncture device is suitable for medium-intensity treatment. When the firing component 130 is used to simultaneously fire the first piezoelectric ceramic 121, the second piezoelectric ceramic 122 and the third piezoelectric ceramic 123, the energy density of the plasma is the highest, which is suitable for severe treatment or treatment sites that require a higher energy density.

[0063] Through the design of the switching member 132, the firing of different numbers of piezoelectric ceramics can be achieved, thereby enabling precise control of the plasma energy density. This not only improves the flexibility and adaptability of the acupuncture device, but also enables the acupuncture device to adjust the energy density of the plasma output according to different diseases or the tolerance levels of different patients to meet diverse treatment requirements.

[0064] Please refer to Figure 4 and Figure 5 In some embodiments, the switching member 132 includes a body portion 1321 and a connecting portion 1322 protruding from the body portion 1321. The switching member 132 is configured to be driven by the driving member 131 to move in a direction close to the plasma generating component 120, so that the connecting portion 1322 cooperates with the piezoelectric ceramic. Since the connecting portion 1322 protrudes from the body portion 1321, when the switching member 132 is switched to the working portion 1242 under the drive of the driving member 131, the connecting portion 1322 can effectively contact the piezoelectric ceramic, so that the piezoelectric ceramic can generate a stable current to ionize the air, thereby ensuring the stability of plasma generation.

[0065] Please refer to Figure 4 and Figure 5In some embodiments, the connecting portion 1322 includes a first contact 13221, a second contact 13222, and a third contact 13223 arranged at intervals between each other. The switching member 132 is configured to rotate relative to the plasma generating assembly 120, such that the first contact 13221 is positioned on the first piezoelectric ceramic 121, the second contact 13222 is positioned on the second piezoelectric ceramic 122, and the third contact 13223 is positioned on the third piezoelectric ceramic 123. It should be noted that the rotation of the switching member 132 can be manually driven or driven by other driving mechanisms. Specifically, when the switching member 132 rotates, the connecting portion 1322 can be positioned on different piezoelectric ceramics respectively, realizing the firing of different numbers of piezoelectric ceramics. Specifically:

[0066] The first contact 13221 is located on the first piezoelectric ceramic 121: When the switching element 132 rotates to a certain position, the first contact 13221 is located on the first piezoelectric ceramic 121, thereby realizing the firing of the first piezoelectric ceramic 121.

[0067] The second contact 13222 is positioned relative to the second piezoelectric ceramic 122: When the switching element 132 continues to rotate to another position, the second contact 13222 is positioned relative to the second piezoelectric ceramic 122, thus triggering the second piezoelectric ceramic 122. At this time, the first contact 13221 can be aligned with the first piezoelectric ceramic 121 or offset from it. For ease of explanation, the following description will use the example of the first contact 13221 being aligned with the first piezoelectric ceramic 121 and the second contact 13222 being aligned with the second piezoelectric ceramic 122.

[0068] The third contact 13223 is positioned relative to the third piezoelectric ceramic 123: When the switching element 132 rotates further to another position, the third contact 13223 is positioned relative to the third piezoelectric ceramic 123, thus triggering the third piezoelectric ceramic 123. Similarly, at this time, the first contact 13221 can be aligned with or offset from the first piezoelectric ceramic 121. The second contact 13222 can be aligned with or offset from the second piezoelectric ceramic 122. For ease of explanation, the following description will take the case where the third contact 13223 is aligned with the third piezoelectric ceramic 123, the first contact 13221 is aligned with the first piezoelectric ceramic 121, and the second contact 13222 is aligned with the second piezoelectric ceramic 122 as an example.

[0069] By setting multiple contacts, the switching element 132 can achieve precise control over different numbers of piezoelectric ceramics, thereby realizing plasma output with different energy densities. This improves the flexibility and adaptability of the acupuncture device, and also allows the device to adjust the energy density of the plasma output according to different symptoms or patients' tolerance levels to meet diverse treatment needs.

[0070] Please see Figure 4 and Figure 5 In some embodiments, the switching element 132 further includes a toggle part 1323 connected to the periphery of the main body 1321. The housing 110 has an adjustment groove, and the toggle part 1323 passes through the adjustment groove and protrudes from the housing 110, so that the toggle part 1323 can be driven to rotate the main body 1321. Specifically, the design of the toggle part 1323 allows the switching element 132 to be rotated by external operation. The toggle part 1323 is connected to the periphery of the main body 1321 and passes through the adjustment groove out of the housing 110, so that the user can drive the main body 1321 to rotate by toggling the toggle part 1323, thereby allowing the switching element 132 to be switched between different positions, thereby achieving the firing of different numbers of piezoelectric ceramics. In other words, by providing the toggle part 1323, the user can achieve the position switching of the switching element 132 through simple operation, thereby achieving the firing of different numbers of piezoelectric ceramics. This not only improves the portability and practicality of acupuncture devices, but also enables them to better serve the needs of clinical treatment.

[0071] Please see Figure 2 and Figure 3 To further reduce the size of the acupuncture device and improve its portability, in some embodiments, the firing assembly 130 and the conduction assembly 140 are arranged on opposite sides of the plasma generating assembly 120. Specifically, the firing assembly 130 and the conduction assembly 140 are respectively arranged on opposite sides of the plasma generating assembly 120, making full use of the internal space of the entire device and reducing unnecessary space waste. In addition, this design allows the two to work together effectively during operation to generate and discharge plasma, improving the working efficiency of the acupuncture device.

[0072] Please see Figure 2 In some embodiments, the handheld acupuncture device 100 provided in this application further includes a heating component 150, which includes a power supply and a heating element 151 electrically connected to the power supply. The heating element 151 is configured to heat the plasma. It should be noted that in this application, piezoelectric ceramics generate plasma, which is then guided to the skin via a conduction component 140. The plasma directly contacts the acupoints on the skin to generate electrical stimulation, thereby achieving the effect of "needle therapy." Simultaneously, the heating element 151 heats the plasma, ensuring that the plasma acting on the acupoints has a certain temperature (this temperature can be higher than the human body temperature but within a safe temperature range that will not burn the skin). Furthermore, the heating element 151 can adjust the output temperature to regulate the plasma temperature, facilitating vasodilation, promoting blood circulation, enhancing treatment and tissue repair effects, and achieving the effect of "moxibustion."

[0073] Please seeFigure 2 and Figure 3 The conduction component 140 includes a funnel-shaped outlet 141. The outlet 141 includes a first opening end 1411 and a second opening end 1412 disposed opposite to each other. The opening size of the first opening end 1411 is larger than the opening size of the second opening end 1412, and the first opening end 1411 faces the plasma generating component 120 to facilitate plasma acquisition. The larger opening size of the first opening end 1411, facing the plasma generating component 120, is designed to allow plasma to enter the outlet 141 more easily, thereby achieving effective plasma collection. The smaller opening size of the second opening end 1412 is used to outlet the plasma, allowing the plasma to be outleted in a concentrated manner, thereby achieving effective plasma outlet.

[0074] In some embodiments, the heating element 150 is disposed around the periphery of the outlet member 141, and the heating element 150 is located within the receiving cavity 111. Specifically, the heating element 150 is disposed around the periphery of the outlet member 141 so that the heating element 151 can uniformly heat the outlet plasma. The power supply is configured to provide sufficient power to the heating element 151 so that it can stably output heat, thereby improving the effect of acupuncture treatment.

[0075] In some embodiments, the handheld acupuncture device 100 is further provided with a button, which can be used to control the start and stop of the acupuncture device, and also to control the number of piezoelectric ceramics engaged with the switching element 132, thereby controlling the energy density of the plasma output. It should be noted that, in some embodiments, the start and stop of the acupuncture device or the energy density of the plasma output can be controlled by the duration or number of times the button is pressed.

[0076] It should be noted that if the embodiments of the present invention involve directional indications (such as up, down, left, right, front, back, etc.), the directional indications are only used to explain the relative positional relationship and movement of the components in a specific posture. If the specific posture changes, the directional indications will also change accordingly.

[0077] Furthermore, if the embodiments of this invention involve descriptions such as "first" or "second," these descriptions are for descriptive purposes only and should not be construed as indicating or implying their relative importance or implicitly specifying the number of technical features indicated. Therefore, a feature defined with "first" or "second" may explicitly or implicitly include at least one of those features. Additionally, the use of "and / or," "and / or," or "and / or" throughout the text implies three parallel solutions. For example, "A and / or B" includes solution A, solution B, or a solution where both A and B are satisfied simultaneously. Furthermore, the technical solutions of the various embodiments can be combined with each other, but this must be based on the ability of those skilled in the art to implement them. When the combination of technical solutions is contradictory or impossible to implement, it should be considered that such a combination of technical solutions does not exist and is not within the scope of protection claimed by this invention.

[0078] The above are merely preferred embodiments of the present invention and do not limit the scope of the patent. Any equivalent structural transformations made using the contents of the specification and drawings of the present invention under the inventive concept of the present invention, or direct / indirect applications in other related technical fields, are included within the scope of patent protection of the present invention.
