[0036] The core of the utility model is to provide a microwave ear radiator, which can be directly worn on the ear and can be inserted into the ear canal. It is easy to use and has a significant therapeutic effect.

[0037] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0038] Please refer to Figures 3 to 15 Schematic diagram of a microwave ear radiator provided in a specific embodiment of the present invention.

[0039] In a specific embodiment, the microwave ear radiator provided by the present invention has an earphone shape, including an outer shell 5 and a front cover 1 that are snap-connected and have a cavity inside, and a reflection cavity 6 arranged in the cavity. The front cover 1 has a treatment part 11 that can be extended into the ear canal, and the reflection cavity 6 is provided with a groove 61 at a position corresponding to the treatment part 11, and the opening of the groove 61 faces the treatment part 11. A wire passage 51 is provided in the outer shell 5, and the antenna 2 passes through the wire passage 62 of the reflection cavity 6 and the wire passage 51 of the outer shell 5. The front end of the antenna 2 is arranged in the groove 61, and the rear end of the antenna 2 passes through the wire passage 51 and is connected to the quick connector 4.

[0040] In the above structure, the microwave ear radiator transmits microwave energy to human tissue through the radiator. Absorbed by water molecules in the tissue, it generates a thermal effect, achieving the therapeutic effect. This treatment method features non-contact heating, simple operation, accurate positioning, high safety, precise therapeutic effect, and rapid onset. It is suitable for treating a variety of ear diseases, such as otitis media.

[0041] The microwave ear radiator comprises a housing 5, a front cover 1, and a reflective cavity 6. The housing 5 and front cover 1 snap together, creating an earphone-like design that can be worn directly on the ear for ease of use. The front cover 1 includes a treatment portion 11 that extends into the ear canal, directly reaching the affected area.

[0042] The housing 5 and front cover 1 contain a chamber, within which a reflective cavity 6 is located. The design of the reflective cavity 6 allows for more concentrated microwave energy, improving treatment efficiency. The front end of the reflective cavity 6 has a groove 61, which is positioned correspondingly to the treatment portion 11 and opens toward the treatment portion 11. This groove 61 reflects microwaves emitted from the rear end forward, further concentrating the energy and enabling more precise targeting of the lesion during treatment.

[0043] A wire passage 51 is provided in the shell 5, and a wire passage 62 is provided in the reflection cavity 6. The antenna 2 passes through the wire passage 62 of the reflection cavity 6 and the wire passage 51 of the shell 5. The front end of the antenna 2 is set in the groove 61, and the rear end of the antenna 2 passes through the wire passage 51 and is connected to the quick connector 4. The quick connector 4 is used to be plugged into the machine, and the antenna 2 is easy to connect.

[0044] The microwave ear radiator provided by the present invention has an internal reflective cavity 6, which optimizes the transmission and distribution of microwaves, making treatment more precise and efficient. This design is an important component of microwave therapy technology and is of great significance for improving treatment efficacy and safety.

[0045] Based on the above specific embodiments, the inner surface of the groove 61 is covered with a metal layer.

[0046] In one specific embodiment, utilizing the principle of microwave reflection, a metal layer, such as aluminum, is applied to the inner surface of groove 61. This reflection enhances the microwave intensity within the treatment area, helping to improve the therapeutic effect. Furthermore, the metal layer reflects microwaves emitted toward the rear end forward, concentrating the energy and precisely controlling the direction and intensity of the sound waves for directional radiation. This concentrated energy also helps minimize damage to surrounding healthy tissue, making the treatment safer and more effective.

[0047] Based on the above specific embodiments, the groove 61 gradually expands from the deepest part to the opening.

[0048] In one specific embodiment, the groove 61 of the reflective cavity 6 is designed to gradually expand outward from its deepest point, forming a fan-shaped or trumpet-shaped structure that gradually widens from narrow to wide. In the design of a microwave therapeutic device, the fan-shaped or trumpet-shaped groove structure of the reflective cavity 6, with a metal layer covering the front end, can effectively concentrate microwave energy and reflect it forward. This design not only helps to increase the microwave energy density in the treatment area, thereby enhancing the therapeutic effect, but also reduces energy loss and improves the efficiency of the entire system. In addition, this structure can also reduce stress concentration in the reflective cavity 6, improving its durability and reliability, which is very important for ensuring the long-term stable operation of medical equipment.

[0049] It should be noted that, during the design, various factors need to be considered, including the shape, size, and depth of the groove 61 and the material and thickness of the metal layer, to ensure optimal performance.

[0050] Based on the above-mentioned specific embodiments, the side walls of the groove 61 are connected by a plurality of sector-shaped surfaces.

[0051] In one specific embodiment, the fan-shaped grooves can optimize the propagation path of microwave energy, enhance the intensity of microwaves at specific frequencies, and increase the microwave energy density in the treatment area, thereby enhancing the therapeutic effect. The fan-shaped grooves can achieve different microwave propagation effects by adjusting parameters such as angle, providing greater flexibility. The fan-shaped grooves have a relatively simple structure, a more convenient manufacturing process, and lower processing costs.

[0052] Of course, the groove 61 may also be a trumpet-shaped groove, which can also make the microwave energy more concentrated and improve the treatment effect.

[0053] Based on the above-mentioned specific embodiments, the inner end of the sector-shaped surface is connected to the circular surface, and the wire channel 62 is opened on the circular surface. The sector-shaped surface smoothly connects the opening and the circular surface, two surfaces of different shapes and sizes. The connection between the sector-shaped surface and the circular surface can provide a sturdy structure, making the overall design more stable when bearing force; the antenna 2 passes through the wire channel 62, which can ensure the neatness and safety of the line, and is convenient for maintenance and replacement.

[0054] On the basis of the above-mentioned specific embodiments, it also includes a pressing block 3 and a wire clamp 7 arranged in the chamber, the pressing block 3 has a wire passage 31 that connects to the wire passage 51 and the wire passage 62, the wire clamp 7 is installed at the inlet end of the wire passage 51, and the outlet end of the pressing block 3 is pressed into the inlet end of the wire clamp 7 so that the wire clamp 7 clamps the antenna 2.

[0055] In a specific embodiment, the pressing block 3 and the wire hoop 7 are connected between the reflection cavity 6 and the wire passage 51. The pressing block 3 has a wire passage 31. The wire hoop 7 is installed at the inlet end of the wire passage 51. The inlet end of the wire passage 51 and the inlet end of the wire passage 31 are connected by the wire hoop 7, so that the wire passage 31 connects the wire passage 51 and the wire passage 62 to form a continuous closed channel. The antenna 2 passes through the reflection cavity 6, the pressing block 3, the wire hoop 7, and the channel of the housing 5 in turn to ensure that the antenna 2 passes from one area to another while keeping the antenna 2 neat and orderly.

[0056] The pressing block 3 is used to fix or guide the antenna 2 to pass through the cavity. The wire outlet end of the pressing block 3 is the part of the pressing block 3 used to output the antenna 2.

[0057] Wire clamp 7 is used to secure antenna 2. Wire clamp 7 is annular or has another shape. The wire entry end of wire clamp 7 is the portion of wire clamp 7 that receives antenna 2 and secures antenna 2 in place. Wire clamp 7 has a certain degree of elasticity or adjustability to accommodate antennas 2 of varying diameters, ensuring smooth passage and securement.

[0058] By pressing the outlet of the press block 3 into the inlet of the wire clamp 7 and squeezing the wire clamp 7, the clamp 7 is activated, activating its tightening mechanism. The clamp 7 clamps the antenna 2, securing and sealing the antenna 2. The use of the press block 3 and the wire clamp 7 prevents the antenna 2 from coming into contact with components that could cause a short circuit or other dangerous conditions, prevents it from accidentally falling off, and prevents it from being pulled out. This reduces damage to the antenna 2 caused by vibration or accidental pulling, thereby improving device reliability.

[0059] Based on the above-mentioned specific embodiments, the housing 5 is in a funnel shape at the inlet end of the wire passage 51, the wire clamp 7 and the outlet end of the pressing block 3 that cooperate with each other. The wire clamp 7 has an axial tightening groove 71, and the outlet end of the pressing block 3 is inserted into the inlet end of the wire clamp 7 to gather the tightening groove 71 of the outlet end of the wire clamp 7.

[0060] In a specific embodiment, the wire hoop 7 is inserted into the inlet end of the wire passage 51. Before the pressing block 3 enters the wire hoop 7, the wire hoop 7 is fitted and connected to the inlet end of the wire passage 51, which is the entrance for the antenna 2 to enter the wire passage 51. The funnel-shaped pressing block 3 is pressed into the funnel-shaped wire hoop 7, which helps to guide the pressing block 3 to smoothly enter the wire hoop 7 and reduce the resistance during press-fitting. After the outlet end of the pressing block 3 is inserted into the wire hoop 7, the tightening mechanism of the wire hoop 7 is activated, that is, when the outlet end of the pressing block 3 is inserted into the wire hoop 7, the tightening groove 71 will gather and tighten along the axial direction, thereby fixing the antenna 2, ensuring that the antenna 2 remains fastened at the connection point to prevent loosening, improving the stability of the connection, and reducing the possibility of the antenna 2 falling off or being damaged due to vibration or accidental pulling.

[0061] Based on the above specific embodiments, the wire hoop 7 includes an inlet cone at the inlet end and an outlet cone at the outlet end. The diameter of the inlet cone is larger than the diameter of the outlet cone. The inlet cone and the outlet cone have connected tightening grooves 71.

[0062] In a specific embodiment, the outlet end of the press block 3 is inserted into the inlet cone, and the size of the inlet cone is more closely matched to the size of the press block 3. The outlet cone matches the diameter of the antenna 2, so that the wire clamp 7 can be tightly fixed to the antenna 2 to prevent the antenna 2 from moving or falling off.

[0063] The tightening slot 71 of the wire hoop 7 allows it to be adjusted according to the diameter of the antenna 2, ensuring that the antenna 2 is effectively secured and sealed when passing through the wire hoop 7. The interconnected tightening slots 71 on the inlet and outlet cones increase the adjustable range of the wire hoop 7, allowing it to be easily tightened or loosened as needed to accommodate antennas 2 of varying diameters, increasing the adaptability and flexibility of the design.

[0064] Based on the above specific embodiments, the incoming end face of the pressing block 3 contacts the outgoing end face of the reflecting cavity 6 , and the channel connecting the wire passage 62 , the threading channel 31 , and the wire passing channel 51 has a turning arc on the pressing block 3 .

[0065] In a specific embodiment, the input end face of the pressing block 3 contacts the output end face of the reflecting cavity 6. Such a design helps to ensure the effective transmission and distribution of microwave energy and the continuity of the channel, avoids damage to the antenna 2 due to channel interruption, and can make the path of the antenna 2 smoother when passing through the device, reduce bending stress, avoid line damage, and also help to maintain the compactness and neatness of the device.

[0066] The design of the turning arc allows the antenna 2 to transition smoothly between different directions. In a small and space-constrained microwave ear radiator, this design can ensure that microwave energy is effectively transmitted to the treatment area while reducing potential damage to surrounding tissues.

[0067] Based on the above-mentioned specific embodiments, the input end face of the pressing block 3 and the output end face of the reflection cavity 6 can be serrated surfaces that cooperate with each other. The design of the serrated surface can provide better mechanical connection, increase the stability of the structure, and reduce the loose connection caused by vibration or impact; the design of the serrated surface allows connection at different angles, which provides more installation flexibility in microwave ear radiators with small size and limited space; the tooth surface increases the contact area, can provide better electromagnetic coupling efficiency, and thus improve the transmission efficiency of microwave energy.

[0068] Of course, the line inlet surface of the pressing block 3 and the line outlet surface of the reflective cavity 6 can also be planes in contact with each other. The design of plane contact simplifies the structure, facilitates manufacturing and assembly, and also reduces potential failure points caused by complex structures.

[0069] On the basis of the above-mentioned specific embodiments, the treatment portion 11 is cylindrical, and the axial direction of the treatment portion 11 coincides with the axial direction of the wire passage 62 .

[0070] In one embodiment, the cylindrical treatment portion 11 conforms to the shape of the ear canal and can be inserted into the ear canal to directly reach the lesion, making it suitable for treating smaller areas of the ear canal. The axial direction of the treatment portion 11 coincides with the axial direction of the wire channel 62, ensuring that microwave energy is directly and effectively delivered to the treatment area, ensuring the accuracy and effectiveness of microwave treatment.

[0071] On the basis of the above-mentioned specific embodiments, the housing 5 and the front cover 1 are fastened together through a snap-fitting slot.

[0072] In one specific embodiment, the chamber formed by the housing 5 and the front cover 1 is an enclosed space for accommodating the reflector cavity 6, the compression block 3, the wire clamp 7, and other possible components. The chamber protects the internal components while providing structural support. The edges of the housing 5 and the front cover 1 are provided with matching slots. When the slots are aligned, they snap together, enabling quick assembly of the front cover 1 and the housing 5. When the slots snap apart, the front cover 1 and the housing 5 can be quickly disassembled, facilitating operation on the production assembly line and facilitating maintenance and upgrades by users or maintenance personnel. The slots of the housing 5 and the front cover 1 have sufficient snapping force to ensure that the housing 5 and the front cover 1 do not accidentally separate during normal use. When the device needs to be sealed to prevent the ingress of dust or moisture, the snap-fitting slot can be used in conjunction with a sealing ring or gasket to provide the necessary protection. The snap-fitting slot design achieves a screwless appearance, making the microwave ear radiator look neater and more aesthetically pleasing. Compared to using screws or other fasteners, the snap-fitting slot can reduce material and assembly costs. The card slot can withstand multiple snapping and detaching without losing its function and can be reused.
