Description

Technical Field

[0001] The invention relates to the technical field of light radiation therapy equipment, and in particular to a high-power infrared therapy instrument lamp head with a liquid filter. Background Art

[0002] Light radiation therapy has a long history. Ancient Egyptians and Indians used sunlight to treat diseases, such as psoriasis. In the late 19th century, with the development of artificial light sources, light radiation therapy began to enter clinical practice. Light of different wavelengths has been clinically proven to have a good effect in wound healing with a red light series of light therapy devices in the 620nm to 650nm band, and a good effect in anti-inflammatory with an infrared light therapy device in the 760nm to 1600nm band. Light in the 810nm band has a good effect in pain relief.

[0003] At the end of the 20th century, Germany invented a new light radiation therapy product called Viagra, which uses a high-power halogen lamp as a light source and filters out the wavelengths that produce thermal effects on the skin through water. Compared with traditional low-power halogen lamps, it has the advantages of greater depth of action and no damage to the skin, and has gradually occupied the traditional light radiation therapy product market.

[0004] In recent years, some existing technologies have emerged, such as:

[0005] Prior art 1, with publication number CN112612095A, is named a structure and assembly process of a filter lens. This prior art 1 introduces the structure and assembly process of the filter lens in detail, solves the problems of fixing two lenses for sealing the filter liquid and adding liquid, and is provided with a heat sink to dissipate heat in time to prevent the liquid from exploding in the sealed space due to excessive temperature. However, the heat sink is welded to the lens body bracket after being spliced ​​with several fin units, which obviously requires a lot of work. The installation of the lens is done by gluing, which is very cumbersome to operate, and the glue must be waited for to solidify, which places high demands on the installers, and undoubtedly increases the production cycle and cost.

[0006] Prior art 2, with publication number CN104689483A, is named an optical therapy device; prior art 3, with publication number CN104689482A, is named a special-shaped reflector cup for a phototherapy device, which provides an optical therapy device with a liquid filter lens having a small volume and good sealing performance, and adopts a special reflector cup to improve the energy utilization rate. From the perspective of the reflector cup, it is made of PC plastic material and is not resistant to high temperatures. Since the halogen lamp generates severe heat and the temperature of the bulb is very high, the power of the halogen lamp is limited. Therefore, a small lamp head can be used, and the reflector cup contour adopts a parabola to increase the focusing effect, and its light energy density is improved, but the irradiation area is limited, and the filament of the halogen lamp is generally large in size and cannot be regarded as a point light source, and the ideal illumination distribution cannot be obtained by defocusing.

[0007] Therefore, based on the above technical problems, technicians in this field urgently need to develop a high-power infrared therapeutic device lamp head with a liquid filter. Summary of the invention

[0075] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below with reference to the accompanying drawings.

[0076] See also Figures 1 to 9 As shown;

[0081] A high-power halogen lamp 403 is arranged inside the lamp holder housing 1, and a free-form reflective cup 3 is arranged between the high-power halogen lamp 403 and the liquid filter 2;

[0082] An infrared temperature measuring device 601 is provided at the lower part of one end of the liquid filter 2 of the lamp holder housing 1 , and a distance indicating rod 602 is also provided at the front end of the lamp holder housing 1 .

[0083] Firstly, the present embodiment further defines the structure of the lamp housing 1. To facilitate the integration of the above components, an annular limiting protrusion 101 is formed inwardly protruding near both ends of the lamp housing 1 of the present embodiment.

[0084] A first mounting plate 102 is mounted on the outer side of the annular limiting protrusion 101 close to one end of the liquid filter mirror 2;

[0085] A second mounting plate 103 is mounted on the outer side of the annular limiting protrusion 101 close to one end of the heat dissipation fan assembly;

[0086] A heat-insulating light-shielding tube 104 is installed between the first mounting plate 102 and the second mounting plate 103, and the high-power halogen lamp 403 and the free-form reflective cup 3 are both located in the heat-insulating light-shielding tube 104;

[0087] The liquid filter 2 and the free-form reflective cup 3 are both assembled and fixed in the lamp housing 1 through the first mounting plate 102, and the heat insulation protection cover 7 is located at the front end of the lamp housing 1 and fixed on the liquid filter 2;

[0088] The cooling fan assembly and the lamp holder housing rear cover 106 are both assembled and fixed to the lamp holder housing 1 via the second mounting plate 103 . A handle 108 is also mounted on the lamp holder housing rear cover 106 .

[0089] Two annular limiting protrusions 101 are arranged inside the lamp holder housing 1 of the present embodiment, and a first mounting plate 102 and a second mounting plate 103 are respectively installed by using the annular limiting protrusions 101; wherein, the first mounting plate 102 is used to install the liquid filter 2 and the free-form reflective cup 3 of the present embodiment; a lamp holder fan mounting plate 401 is arranged at one end of the outer side of the second mounting plate 103, and the second mounting plate 103 and the lamp holder fan mounting plate 401 are positioned by a positioning ring 105; a lamp holder 402 is installed at one end of the lamp holder fan mounting plate 401 facing the inside of the lamp holder housing 1, and a high-power halogen lamp 403 is installed on the lamp holder 402; a cooling fan 501 is installed at one end of the lamp holder fan mounting plate 401 facing the outside of the lamp holder housing 1, and a wiring harness adapter plate 404 is also arranged on the lamp holder fan mounting plate 401.

[0090] The first mounting plate 102 and the second mounting plate 103 of this embodiment are assembled into a whole through the heat-insulating light-shielding tube 104 therebetween, and the annular limiting protrusion 101 is used to maintain the relative position and fix it with the lamp holder housing 1. The second mounting plate 103 of this embodiment is connected and fixed to the lamp holder housing back cover 106 and the lamp holder fan mounting plate 401 through the lamp holder back cover fixing screws 107, and a lamp holder 402 for mounting a high-power halogen lamp 403, a cooling fan 501 and a harness adapter plate 404 are arranged on the lamp holder fan mounting plate 401. The harness adapter plate 404 of this embodiment is used to connect the lamp holder bus to various required components through adapters after entering the lamp holder, so as to facilitate subsequent maintenance operations such as replacement of bulbs. Among them, the positioning ring 105 of this embodiment is located between the second mounting plate 103 and the lamp holder fan mounting plate 401 to ensure that the front and rear positions of the high-power halogen lamp 403 relative to the free-form reflector cup 3 are consistent with the relative positions designed by the optimal illumination distribution diagram simulated by the software. The circular structure of the entire interior can well ensure the coaxiality of optical related components.

[0091] Preferably, the liquid filter 2 of this embodiment includes:

[0092] An annular liquid cavity 201, the center of the annular liquid cavity 201 is a light outlet 20101, and the outer peripheral surface of the annular liquid cavity 201 has heat dissipation teeth 20103;

[0093] an annular liquid cavity rear cover 204 assembled and fixed to the annular liquid cavity 201; and

[0094] A first window piece 202 and a second window piece 203 are disposed in the annular liquid cavity 201;

[0095] An isolation and limiting ring 205 is provided between the first window piece 202 and the second window piece 203 to compress the two window pieces and limit the relative positions in the axial and radial directions. Meanwhile, the isolation and limiting ring 205 also has openings so as not to affect the injection of the filter liquid.

[0096] In this embodiment, the position where the annular liquid cavity 201 and the annular liquid cavity back cover 204 cooperate is processed with an annular liquid cavity back cover sealing groove 211, and an annular liquid cavity back cover sealing ring 208 is compressed in the annular liquid cavity back cover sealing groove 211;

[0097] A first window sheet sealing groove 209 is processed at the position where the annular liquid cavity 201 cooperates with the first window sheet 202, and a first window sheet sealing ring 206 is compressed in the first window sheet sealing groove 209;

[0098] A second window sheet sealing groove 210 is processed at the position where the annular liquid cavity rear cover 204 cooperates with the second window sheet 203 , and a second window sheet sealing ring 207 is compressed in the second window sheet sealing groove 210 .

[0099] A filter liquid receiving chamber 212 is formed between the annular liquid cavity 201 and the annular liquid cavity rear cover 204, and the annular liquid cavity rear cover 204 is provided with a liquid injection hole 213 connected to the filter liquid receiving chamber 212, and the filter liquid is injected into the filter liquid receiving chamber 212 through the liquid injection hole 213. The filter liquid receiving chamber 212 of this embodiment is an I-shaped chamber, which greatly increases the contact area between the filter liquid and the annular liquid cavity 201 while ensuring the required liquid layer thickness, and can timely take away the heat generated by absorbing the spectral band energy that the human body cannot tolerate, so as to avoid the internal filter liquid temperature being too high. At the same time, a certain volume of air is left above the window sheet, which can ensure that all the emitted light is filtered by the filter liquid while balancing the pressure of the filter liquid receiving chamber 212, and the compressed air prevents the filter liquid from having an excessively high saturated vapor pressure.

[0100] The specific structure and assembly process of the liquid filter 2 of the present embodiment are as follows: it mainly comprises an annular liquid cavity 201 and an annular liquid cavity back cover 204 installed in the annular liquid cavity 201, wherein, according to the positions of the above-mentioned window pieces, window piece pressure rings and sealing rings, they are assembled into the annular liquid cavity, and then the annular liquid cavity back cover 204 is fixed to the annular liquid cavity 201 by screws.

[0101] In this embodiment, four reinforcing ribs 20102 are evenly distributed on the outer circumference of the annular liquid cavity 201, and the reinforcing ribs 20102 extend outward along the radial direction of the annular liquid cavity 201; a plurality of heat dissipation teeth 20103 are formed at equal intervals between adjacent reinforcing ribs 20102;

[0102] Heat dissipation gear 20103 includes:

[0103] A heat dissipation tooth connection portion integrally formed with the outer wall of the annular liquid cavity 201; and

[0104] Two heat dissipation sub-teeth separated from each other are formed at the outer end of the heat dissipation tooth connection portion.

[0105] The middle part of the annular liquid cavity 201 of the present embodiment is the light outlet 20101 of the entire lamp holder, four reinforcing ribs 20102 for installation are arranged on the periphery, and a plurality of heat dissipation teeth 20103 are evenly distributed at equal intervals. The periphery of the annular liquid cavity 201 of the present embodiment can be integrally formed by aluminum profiles and only the interior needs to be processed.

[0106] When installing the liquid filter, just place the annular liquid cavity 201 horizontally with the opening facing upwards, and then put in the first window piece sealing ring 206, the first window piece 202, the isolation limit ring 205, the second window piece 203, the second window piece sealing ring 207, the annular liquid cavity back cover sealing ring 208, and the annular liquid cavity back cover 204 in sequence, and finally connect the annular liquid cavity back cover 204 with the annular liquid cavity 201 with screws to complete the assembly; then stand up the liquid filter 2, and at the same time make the injection port 213 at the highest point, use a syringe to inject the filter liquid according to the specified volume, and after completion, screw in the screws with the sealing gasket to seal it.

[0107] Preferably, the free-form surface reflector cup 3 of this embodiment includes:

[0108] Reflective cup body 301;

[0109] A reflective cup mounting edge 302 formed at one end of the reflective body 301 and the first mounting plate 102;

[0110] The inner surface of the reflective cup body 301 is formed into a plurality of local curved protrusions 303 .

[0111] Since the filament size of the high-power halogen lamp 403 is relatively large, the light power density at the center of the traditional parabolic reflector cup is too high while the light power density at the edge is too low, and the light is excessively diverged and loses too much energy. Therefore, the present invention lengthens the size of the reflector cup and adopts segmented free-form surface partition reflection and superimposes it on the target irradiation distance surface. Finally, by adjusting the surface shape of each segment of the curved surface, the overall light energy of the target irradiation area is maximized and the overall energy distribution is more uniform. Due to the different specific geometric shapes of the light-emitting filament, the target irradiation area will produce a reflected image of the filament, which affects the local uniformity of the illuminated area. To solve this problem, a local curved surface protrusion 303 is introduced on the inner surface of the free-form surface reflector cup 3, so that the local illuminance can also reach a very uniform state. The final illuminance distribution simulation diagram at 25cm is obtained, see Fig.10 and Fig.11 shown.

[0112] Also, see Figure 8 and Fig. 9 As shown, the specific structure of the local curved surface protrusion 303 of this embodiment is:

[0113] First, the curve 304 obtained by cutting the smooth inner surface is divided into a plurality of curve segments, and arcs protruding inward are drawn at the two end points of the curve segments, and the plurality of arcs form a contour curve 305;

[0114] Secondly, take a plane perpendicular to the center line 306 of the reflector cup, and draw a circle with a diameter greater than or equal to the opening diameter of the reflector cup with the intersection point O of the plane and the center line 306 of the reflector cup as the center. Similarly, divide the circle into several arcs, and draw arcs protruding toward the center O with the two end points of the arcs. Several arcs form a closed path 307;

[0115] Finally, for any point A on the contour curve 305, the closed path 307 is reduced at a specific ratio with the center O as the reference point and translated along the center line 306 of the reflector cup to make it coincide with point A. At this time, point A can be scanned along this path for one circle; similarly, for other points on the contour curve 305, they can be scanned in this way; finally, the contour curve 305 scans the inner surface of the reflector cup with a plurality of local protrusions 303 around the center line 306 of the reflector cup along the closed path 307.

[0116] The free-form reflective cup 3 of the present embodiment is made of high-temperature resistant aluminum alloy, processed by spinning or stamping, and the inner reflective surface is surface treated to make it have a very high reflectivity.

[0117] Preferably, a cooling fan protection net 502 is provided at one end of the cooling fan 501 of this embodiment;

[0118] The cooling fan 501 forms a gas flow direction from one end of the heat insulation protection cover 7 to one end of the cooling fan 501;

[0119] The first mounting plate 102 , the second mounting plate 103 and the lamp holder fan mounting plate 401 are all provided with openings for air to flow through.

[0120] When the lamp holder of this embodiment is working, the light emitted by the high-power halogen lamp 403 is reflected by the free-form reflector cup 3 and irradiates the skin surface through the liquid filter 2; during treatment, the distance between the irradiated skin and the light outlet should be greater than the length of the indicator rod 602, and the infrared temperature measuring device 601 monitors the skin temperature in real time to avoid burns. The heat-insulating protective cover 7 can prevent the user from adjusting the irradiation position through the handle 108 and other actions that may cause the liquid filter 2 to be accidentally touched and dirty the window piece, affecting the light output efficiency or scalding the user. The filter liquid in the liquid filter 2 absorbs most of the light radiation energy, causing the temperature to rise, and the heat is transferred to a large number of heat dissipation teeth 20103 on the edge by heat conduction. The air flow generated by the heat dissipation fan 501 when it is working takes away the heat from the heat dissipation teeth 20103 and the inside of the lamp holder in the fan airflow direction 503. The first mounting plate 102, the second mounting plate 103, and the lamp holder fan mounting plate 401 all have openings for air to flow through, and a temperature sensor is provided inside the lamp holder. When the fan fails or other circumstances cause the temperature inside the liquid filter 2 and the lamp holder to be too high, the high-power halogen lamp 403 is automatically turned off to ensure the safety of the user.

[0121] In the above technical solution, the high-power infrared therapeutic device lamp head with a liquid filter provided by the present invention has the following beneficial effects:

[0122] The therapeutic instrument lamp holder of the present invention integrates a liquid filter 2 at the light emitting end of the lamp holder housing 1, a cooling fan 501 is arranged at the other end, and a high-power halogen lamp 403 and a free-form surface reflective cup 3 are integrated inside. The entire structure is easy to install and has the characteristics of low cost, uniform energy distribution, balance of light power density and irradiation area, good heat dissipation effect and high safety.

[0123] The above description is only by way of illustration of certain exemplary embodiments of the present invention. It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention. Therefore, the above drawings and descriptions are illustrative in nature and should not be construed as limiting the scope of protection of the claims of the present invention.
