[Technical Field]

[0001] (CROSS-REFERENCE TO RELATED APPLICATIONS) This application claims priority to a Chinese patent application entitled "Far-infrared irradiation device and far-infrared irradiation earmuffs for the middle ear and inner ear" (application number 202311417038.4), filed on October 30, 2023, the contents of which are incorporated herein by reference.

[0002] The present invention relates to the technical field of medical auxiliary devices, and in particular to a far-infrared irradiating device for the middle ear and inner ear and far-infrared irradiating earmuffs. [Background technology]

[0003] According to otolaryngologists, hearing loss generally begins after the age of 50. As we age, metabolism slows, causing the blood vessels in the inner ear to harden and narrow, affecting blood circulation and impeding the supply of nutrients to ear cells. This affects the microcirculation of the auditory nerve, leading to hearing aging—hardening of the auditory bone and a decline in the reception of high-frequency sounds. 70 to 80 percent of tinnitus cases are caused by a decline in high-frequency hearing. To slow the aging of hearing, we need to protect our ears better in our daily lives and prevent damage. In addition to supplementing our nutritional intake through diet, promoting blood circulation aids metabolism, improves blood circulation, and has the effect of delaying or even improving hearing loss.

[0004] Far infrared rays in the wavelength range of 8 μm to 12 μm resonate with molecules in the human body, promoting capillary dilation, smoothing blood circulation, and stimulating metabolism, thereby boosting the body's immune system. Therefore, in addition to applications in science and technology and astronomy, far infrared rays are also used in medicine and health management. For example, far infrared rays are often used when blood stagnation or poor circulation occurs.

[0005] Currently, far-infrared irradiation devices typically use optical waveguides to irradiate small cavity structures in the human body, converging the far-infrared rays to the ear through a waveguide. However, due to the small area of ​​the ear canal, the area on which the far-infrared rays converge and radiate through the waveguide is limited, resulting in poor irradiation effectiveness. Furthermore, the irregular structure and small area of ​​the ear make it impossible to use a large-area flat irradiator. DISCLOSURE OF THE INVENTION

[0008] The present invention is based on the above technical scheme and includes the following improvements.

[0024] The principles and features of the present invention will be explained below in conjunction with the drawings. The examples given below are intended to be illustrative of the present invention and are not intended to limit the scope of the present invention.

[0025] Unless otherwise specified, the terms "installed," "connected," and "coupled" should be understood in a broad sense, such as a fixed connection, a detachable connection, a one-piece structure, etc. Those skilled in the art can understand the specific meaning of such terms in the present invention depending on the specific circumstances.

[0026] Far-infrared rays are a type of light wave, generally divided into near-infrared rays with a wavelength range of 0.766μm to 4μm and far-infrared rays with a wavelength range of 4μm to 400μm. Clinical experiments have shown that biochemical far-infrared rays have a wavelength close to that of the human body, 8μm to 12μm, which resonates easily with the human body and has effects such as warming, massaging, promoting blood circulation, and activating cells, making them an essential light for plants and animals. 65-70% of the human body, and approximately 60-95% of our cells, are water. The resonant active wavelength of water is approximately 8μm to 10μm.

[0027] The present invention provides a far-infrared irradiation device for the middle ear and inner ear and far-infrared earmuffs that irradiate far-infrared rays to the human ears, promote metabolism, improve blood circulation, and delay or improve hearing loss by irradiating far-infrared rays of a corresponding wavelength to the ears, thereby effectively protecting the ears and delaying the aging of hearing.

[0028] As shown in Figure 1, the far-infrared irradiation device for the middle ear and inner ear designed by this invention comprises a conical element 1, a heating element 3.3 and a waveguide 2, a large opening 1.1 and a small opening 1.2 are provided at both ends of the axial direction of the conical element 1, respectively, a conical surface 1.4 is formed between the large opening 1.1 and the small opening 1.2, and the conical element 1 is connected to the waveguide 2 via the small opening 1.2.

[0029] The large opening 1.1 of the conical element 1 is provided with a first far-infrared radiator 3 that radiates far-infrared rays converging from the large opening 1.1 toward the small opening 1.2, and the conical surface 1.4 is provided with a second far-infrared radiator 4 that radiates far-infrared rays diffusing outward from the conical surface 1.4.

[0030] The first far-infrared radiator 3 comprises a metal sheet 3.1 and a first far-infrared radiating film 3.2, the metal sheet 3.1 being in contact with the conical element 1, and the first far-infrared radiating film 3.2 being arranged on the side of the metal sheet 3.1 closer to the large opening 1.1.

[0031] The heating element 3.3 is disposed on the opposite side of the metal sheet 3.1 and heats the metal sheet 3.1 to heat the first far-infrared radiation film 3.2, which then radiates far-infrared rays.

[0032] The second far-infrared radiator 4 comprises a second far-infrared radiating film 4.1 arranged on the outer surface of the conical surface 1.4 of the conical element 1, and the second far-infrared radiating film 4.1 is heated by heat transferred from the metal sheet 3.1 through the conical element 1 and radiates far-infrared rays.

[0033] Specifically, the conical element 1 is a metal element, and when the heating element 3.3 generates heat, part of the heat acts directly on the first far-infrared radiation film 3.2, and the remaining heat is conducted to the second far-infrared radiation film 4.1 via the conical element 1, thereby achieving the effects of two far-infrared radiation films simultaneously.

[0034] Preferably, the conical element 1 is made of metal material, and the outer surface of the conical surface 1.4 is coated with a second far-infrared radiating film 4.1 for better thermal conductivity.

[0035] The far-infrared rays emitted from the first far-infrared radiator 3 converge from the large opening 1.1 to the small opening 1.2 of the conical element 1 and are sent to the ear canal through the waveguide 2. The far-infrared rays diverge along the waveguide 2 into the ear canal, promoting resonance in the ear canal and promoting blood circulation in the ear canal.

[0036] The far-infrared rays emitted from the second far-infrared radiator 4 diffuse outward from the conical surface 1.4 of the conical element 1, causing resonance at a position near the ear canal and promoting blood circulation around the ear.

[0037] In this embodiment, the far-infrared rays generated by the first far-infrared radiator 3 and the second far-infrared radiator 4 cover the entire inside and outside of the ear, thereby widening the coverage area and improving the blood circulation promoting effect.

[0038] In one embodiment, the far-infrared rays emitted from either the first far-infrared radiation film 3.2 or the second far-infrared radiation film 4.1 have a wavelength of 8 μm to 12 μm, and the heating temperature of the metal sheet 3.1 is maintained at 39 to 45°C, preferably 41±1°C.

[0039] The higher the emissivity of far infrared rays, the better (ideally 100% emissivity), but it is also necessary to match the wavelength and temperature of the object to be heated. The average human body temperature is 37°C. According to Wien's displacement law, the most suitable wavelength is 2897 (constant) ÷ (273 + 37) (absolute temperature) = 9.3 μm.

[0040] Therefore, when using far-infrared rays at 37°C, the higher the emissivity of far-infrared rays in the 9.3μm wavelength range, the stronger the power of the far-infrared rays and the greater the effect. Also, the higher the temperature, the stronger the power.

[0041] The normal human body temperature is 36.5℃~37℃, which corresponds to a wavelength of approximately 9μm~9.5μm. When the infrared product is heated to 41℃~50℃ and comes into contact with the human body or skin, the far infrared rays will resonate with the water molecules and bones in the human body.

[0042] In this case, the emissivity of far-infrared rays in the wavelength range of 9 μm to 9.5 μm affects the degree of resonance of the far-infrared rays with the human body.

[0043] When the heating temperature is 41°C, the wavelength is 2897 / (273+41) ≒ 9.2 μm.

[0044] Unit power: Power = σT4, the higher the temperature, the stronger the power.

[0045] Therefore, taking into consideration the optimum wavelength and the operating temperature of the medical device, the heating temperature in this embodiment is set to 39 to 45°C, and optimally to 41±1°C.

[0046] Wien's displacement law is a law of physics that explains the inverse relationship between the peak wavelength of the radiance of the blackbody's electromagnetic radiation spectrum and the temperature of the blackbody itself, and its mathematical formula is as follows:

[0052] In one embodiment, the inner diameter of the large opening 1.1 is D1, the inner diameter of the small opening 1.2 is D2, the cone angle of the conical element 1 is θ, and the shortest straight-line distance between the large opening 1.1 and the small opening 1.2 is D3, where D1, D2, θ, and D3 satisfy the following:

[0053] Preferably, the cone angle θ is between 55 and 65 degrees.

[0054] In this embodiment, the specifications of D1, D2, D3, D4 and the cone angle θ can be adaptively adjusted according to different user groups.

[0055] In one embodiment, specifically referring to FIG. 2, the metal sheet 3.1 is a flat plate, and the inner surface of the conical element 1 is further coated with a reflective film 1.3 that reflects the far-infrared rays emitted from the first far-infrared radiating film 3.2 and converges them toward the small opening 1.2, thereby ensuring that the far-infrared rays emitted from the first far-infrared radiating film 3.2 can fully act within the ear canal.

[0056] In one embodiment, and with particular reference to FIG. 1, the metal sheet 3.1 forms a spherical concave surface towards the large opening 1.1, the radius of the spherical concave surface being D5, and satisfying the following relationship:

[0057] The center of the spherical concave surface is located on one side of the waveguide 2 close to the conical element 1, which improves the focusing effect of the far infrared rays generated by the metal sheet 3.1.

[0058] In one embodiment, the waveguide 2 is made of a light-transmitting material to ensure that the far infrared radiation is sufficiently diffused into the ear canal.

[0059] The present invention further provides far-infrared irradiating earmuffs, which include a pair of earmuff bodies, an elastic arm connected to the pair of earmuff bodies, and a far-infrared irradiating device for the middle ear and inner ear as described above, each earmuff body being provided with a far-infrared irradiating device and a power input device, and the power input device being electrically connected to the heating element 3.3 of the far-infrared irradiating device.

[0060] In this embodiment, the earmuff body directly covers the human ear, ensuring that the waveguide 2 is aligned with the ear canal, and the far-infrared rays emitted from the first far-infrared radiator 3 are accurately irradiated onto the ear canal. At the same time, the second far-infrared radiator 4 radiates far-infrared rays to the position around the ear canal, so that the far-infrared rays cover the entire ear area, promoting blood circulation in the ear and activating cells.
