Description

Technical Field

[0001] The invention belongs to the technical field of optical filters and relates to a light wave irradiation device used for infrared treatment. Background Art

[0002] In modern clinical treatment, halogen lamps are the primary light source for treatment. The light waves emitted by halogen lamps must be processed to filter out those that are prone to thermal effects on the skin, retaining the wavelengths between 450nm and 1550nm that can penetrate the human body's surface. Light waves in this wavelength range can easily penetrate 8cm or even 15cm below the skin, providing deep-seated treatment. To achieve the therapeutic effect, the filter absorbs most of the light waves produced by the halogen lamp, generating a large amount of heat. This can easily cause the lenses in the liquid filter to break, compromising the safety of the device. Furthermore, it can cause the filtrate in the liquid filter to vaporize. There is an urgent need to develop a liquid filter that improves lens safety, effectively reduces halogen lamp temperature, and minimizes filtrate vaporization. This would ensure the safety and stability of the liquid filter, reduce lens failure rates, and extend the life of the filter. Summary of the Invention

[0003] The purpose of the present invention is to provide a light wave irradiation device for infrared treatment in order to solve the above problems.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions:

[0005] A light wave irradiation device for infrared therapy includes a halogen lamp mounted on a halogen lamp fixing bracket inside an irradiation head housing, a ventilation chamber is provided at one end of the irradiation head housing close to the halogen lamp fixing bracket, and a lens is provided at one end of the irradiation head housing close to the halogen lamp. The lens includes two layers of lens covers arranged from the inside to the outside at the opening of the irradiation head housing, a liquid filter device is arranged between the two layers of lens covers, and the liquid filter device includes a first lens and a second lens arranged from the outside to the inside, and the thickness of the first lens is greater than the thickness of the second lens.

[0006] In the above-mentioned light wave irradiation device used for infrared treatment, an axial flow fan is provided in the ventilation chamber, a fan guard is provided at the opening of the ventilation chamber, the fan guard is installed on the irradiation head housing, and the fan guard, axial flow fan and halogen lamp fixing frame are coaxially arranged.

[0007] In the above-mentioned light wave irradiation device used for infrared treatment, the inner circle of the lens cover is the mounting part, and the inner side wall of the mounting part is provided with a lens mounting seat extending radially outward. The edge of the first lens is bonded to the lens mounting seat of the outer lens cover, and the edge of the second lens is bonded to the lens mounting seat of the inner lens cover. An anti-drifting member is provided between the two layers of lens covers to prevent them from shifting in position due to pressure.

[0008] In the above-mentioned light wave irradiation device used for infrared treatment, the depth of the lens mounting seat of the outer lens cover is greater than the thickness of the first lens, and the depth of the lens mounting seat of the inner lens cover is greater than the thickness of the second lens. The space formed between the first lens, the second lens and the mounting portion is a liquid holding chamber, and the inside of the liquid holding chamber is filled with filtrate.

[0009] In the above-mentioned light wave irradiation device for infrared therapy, the mounting portion of the inner lens cover is provided with a liquid injection hole along the axial direction, and the liquid injection hole extends to the liquid receiving chamber.

[0010] In the above-mentioned light wave irradiation device for infrared therapy, the mounting portion of the inner lens cover is provided with a liquid injection hole along the axial direction.

[0011] In the above-mentioned light wave irradiation device for infrared treatment, at least two connecting sections are evenly distributed outside the mounting portion of each lens cover, and the anti-deviating member includes a threaded connection pair installed between the connecting sections of the two layers of lens covers.

[0012] In the above-mentioned light wave irradiation device for infrared treatment, the overall shape of the lens cover is annular, and a plurality of heat sinks are radiated outward from the mounting portion of the lens cover.

[0013] In the above-mentioned light wave irradiation device used for infrared treatment, a reflective tube is arranged on the inner side of the irradiation head shell along its axis, the halogen lamp fixing frame passes through the reflective tube, a condenser is installed on the inner side of the reflective tube, the reflector is connected to the opening of the condenser, the opening of the reflector is arranged opposite to the opening of the condenser, and the other end of the condenser is arranged close to the liquid filter device.

[0014] In the above-mentioned light wave irradiation device for infrared treatment, a spacing area is provided between the opening of the reflector and the opening of the condenser, and the reflector and the condenser are fixed by a connecting piece.

[0015] Compared with the existing technology, the advantages of the present invention are:

[0016] In this invention, the inner and outer lenses of the liquid filter device are designed with different thicknesses, effectively ensuring user safety. The specific principle is that the second lens of the inner lens is slightly thinner than the first lens of the outer lens to prevent the inner lens from being damaged earlier than the outer lens in the event of glass explosion, thereby protecting the user's safety. This solves the problem of the existing technology that halogen lamps generate large amounts of heat that affects the liquid filter device, improves lens safety, reduces lens failure rate, and extends the life of the filter device.

[0017] In this invention, the irradiator housing protects internal components and isolates them from the high-temperature environment. Several heat sinks are radiated outward from the lens cover mounting area to dissipate heat generated by the halogen lamp's light waves, preventing lens rupture and thus protecting the user's safety. A ventilation chamber lowers the temperature within the irradiator housing and promotes air flow.

[0018] In the present invention, the opening of the reflector and the opening of the focusing cover are arranged opposite to each other and are spaced apart from each other, focusing the light beam onto the liquid filter device, ensuring that all light emitted from the irradiation emitter passes through the liquid filter device, and preventing the light from being exposed through the ventilation chamber and the heat sink.

[0019] The present invention allows filtrate to be injected through an injection hole. Once the filtrate is fully injected, the filter is sealed using an injection hole sealing device. The number of injection holes is one, and when liquid is added to the injection hole, gas can be discharged from the injection hole. When the radiator is filled with filtrate, the injection hole utilizes atmospheric pressure to effectively prevent leakage of the internal filtrate. Since there is only one injection hole, the occurrence of filtrate vaporization at high temperatures is reduced, thereby extending the service life of the filter.

[0020] Other advantages, objectives and features of the present invention will be reflected in part from the following description and will be understood by those skilled in the art through study and practice of the present invention. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0025] The present invention will be further described below with reference to specific embodiments.

[0026] like Figure 1 and 3 As shown, a light wave irradiation device for infrared treatment includes a halogen lamp 3 mounted on a halogen lamp fixing frame 2 inside an irradiation head housing 1, a ventilation chamber 5 is provided at one end of the irradiation head housing 1 close to the halogen lamp fixing frame 2, and a lens 6 is provided at one end of the irradiation head housing 1 close to the halogen lamp 3. The lens 6 includes two layers of lens covers 7 arranged from the inside to the outside at the opening of the irradiation head housing 1, a liquid filter device 8 is arranged between the two layers of lens covers 7, and the liquid filter device 8 is provided with a first lens 9 and a second lens 10 from the outside to the inside, and the thickness of the first lens 9 is greater than the thickness of the second lens 10.

[0027] In this embodiment, the inner and outer lenses of the liquid filter device 8 are designed with different thicknesses to effectively ensure user safety. The inner lens (second lens 10) is slightly thinner than the outer lens (first lens 9) to prevent premature damage to the inner lens (second lens 10) in the event of glass shattering, thereby protecting the user. The irradiation head housing 1 protects internal components and isolates them from the high-temperature environment. The ventilation chamber 5 reduces the temperature within the housing 1 and facilitates air flow.

[0028] In a preferred embodiment, an axial flow fan 11 is installed within the ventilation chamber 5. A fan guard 12 is located at the opening of the ventilation chamber 5. The fan guard 12 is mounted on the irradiation head housing 1, with the fan guard 12, axial flow fan 11, and halogen lamp holder 2 coaxially arranged. The operation of the axial flow fan 11 accelerates air flow, reducing the temperature within the cavity of the irradiation head housing 1. A fan guard prevents foreign matter from entering the emitter. Furthermore, it prevents operators from being injured by the high-speed fan. In a preferred embodiment, a light shield 13 is located on the side of the ventilation chamber 5 near the halogen lamp holder 2.

[0029] like Figure 1-3As shown, in a preferred embodiment, the inner ring of the lens cover 7 forms a mounting portion 14. A lens mounting seat 15 extends radially outward from the inner sidewall of the mounting portion 14. The edge of the first lens 9 is bonded to the lens mounting seat 15 of the outer lens cover, and the edge of the second lens 10 is bonded to the lens mounting seat 15 of the inner lens cover. An anti-drift feature 16 is provided between the two layers of lens cover 7 to prevent positional displacement due to pressure. The two layers of lens cover 7 are used to secure the first lens 9 and the second lens 10. The anti-drift feature 16 includes at least two sets of threaded connection pairs installed between the two layers of lens cover 7.

[0030] In a preferred embodiment, the depth of the lens mounting seat 15 of the outer lens cover is greater than the thickness of the first lens 9, and the depth of the lens mounting seat 15 of the inner lens cover is greater than the thickness of the second lens 10. The space formed between the first lens 9, the second lens 10, and the mounting portion 14 is a liquid receiving chamber 17, and the interior of the liquid receiving chamber 17 is filled with filtrate. The space formed between the first lens 9, the second lens 10, and the two layers of lens cover 7 is a liquid receiving chamber 17 for filling with filtrate, and the filtrate filled in the liquid receiving chamber 17 can be a coolant.

[0031] In a preferred embodiment, the mounting portion 14 of the inner lens cover is provided with an injection hole 18 along the axial direction, and the injection hole 18 extends to the liquid receiving chamber 17. In this embodiment, filtrate can be injected from the injection hole 18. After the filtrate is filled, the filter is sealed using the sealing device of the injection hole 18.

[0032] In a preferred embodiment, the inner lens cover mounting portion 14 is provided with a single liquid injection hole 18 along its axial direction. This structure ensures that when liquid is added to the liquid injection hole 18, gas can be discharged through the liquid injection hole 18. Furthermore, when the radiator is filled with filtrate, the liquid injection hole 18 utilizes atmospheric pressure to effectively prevent the filtrate from leaking out. This structure reduces the risk of filtrate vaporization at high temperatures, thereby extending the filter's service life.

[0033] In a preferred embodiment, at least two connecting sections 19 are evenly distributed on the outside of the mounting portion 14 of each lens cover 7 , and the anti-deviating member 16 includes a threaded connection pair installed between the connecting sections 19 of the two layers of lens covers 7 .

[0034] In a preferred embodiment, the lens cover 7 is annular in shape, and a plurality of heat sinks 20 are radiating outward from the mounting portion 14 of the lens cover 7. The heat sinks 20 radiating outward from the mounting portion 14 of the lens cover 7 facilitate dissipating heat generated by the light waves radiated by the halogen lamp, preventing the lens from cracking and thus protecting the user's safety.

[0035] In a preferred embodiment, a reflective tube 21 is disposed along the axis of the inner side of the irradiation head housing 1. The halogen lamp mounting bracket 2 extends through the reflective tube 21. A condenser 22 is mounted on the inner side of the reflective tube 21. The opening of the condenser 22 is connected to a reflector 23. The opening of the reflector 23 is positioned opposite the opening of the condenser 22, and the other end of the condenser 22 is positioned near the liquid filter 8. The reflective tube 21, condenser 22, and reflector 23 collectively focus the light from the halogen lamp onto the liquid filter 8. The bottom wall of the reflective tube 21 ensures that the light emitted by the halogen lamp is focused toward the liquid filter 8, preventing it from escaping from the ventilation chamber 5. The halogen lamp mounting bracket 2 extends through the bottom wall of the reflective tube 21. The condenser 22 is fixed inside the reflective tube 21 to focus the light from the halogen lamp. The opening of the condenser 22 is connected to a reflector 23 for concentrating the light of the halogen lamp onto the liquid filter device 8 to prevent the light from leaking out from the heat sink 20 .

[0036] In a preferred embodiment, a spacing region 24 is provided between the opening of the reflector 23 and the opening of the condenser 22, and the reflector 23 and the condenser 22 are fixed by a connector 25. The opening of the reflector 23 and the opening of the condenser 22 are arranged opposite each other and spaced apart from each other, focusing the light beam onto the liquid filter 8, ensuring that all light emitted from the irradiation emitter passes through the liquid filter 8.

[0037] The working process of this embodiment is as follows: (1) The edge of the first lens 9 is bonded to the lens mounting seat 15 of the outer lens cover, and the edge of the second lens 10 is bonded to the lens mounting seat 15 of the inner lens cover. An anti-drifting member 16 is provided between the two layers of lens cover 7 to prevent the position from being shifted due to pressure. The inner second lens 10 is slightly thinner than the outer first lens 9 to prevent the inner second lens 10 from being damaged before the outer first lens 9 when the glass bursts, thereby protecting the safety of the user. (2) The mounting portion 14 of the inner lens cover is provided with an injection hole 18 along the axial direction, through which the filtrate is injected into the liquid filter device 8. This structure ensures that after the liquid filter device 8 is filled with filtrate, the injection hole 18 can effectively prevent the internal filtrate from leaking out by utilizing atmospheric pressure. This structure reduces the occurrence of filtrate vaporization under high temperature conditions, thereby extending the service life of the filter.
