Description

Technical Field

[0001] The invention relates to the technical field of spectrum therapy equipment, and in particular to a spectrum thermal therapy device with a ventilation and cooling system. Background Art

[0002] Spectral thermal therapy uses a certain band of spectrum to irradiate the surface of the human body, and through the photothermal compound effect, it can effectively kill the diseased cell tissue, coagulate the mucosal tissue, and block the blood vessels to achieve the purpose of healing. Commonly used products in practical applications include visible light therapy, phototherapy, light radiation therapy, photon therapy, red light therapy, and blue light therapy.

[0003] There are many types of spectrum therapy devices on the market, and most of the light sources used are LED, laser, polarized light, fluorescent lamp, and halogen lamp. For spectrum thermal therapy devices using halogen lamps as light sources, the advantage is that they emit a full spectrum, so they are widely applicable. However, a disadvantage of halogen lamps that cannot be ignored is that they generate a lot of heat. The high heat generated by halogen lamps is determined by their structure and working principle. Specifically, the glass shell of the halogen lamp is filled with some halogen element gas, usually iodine or bromine. When working, when the filament heats up, tungsten atoms are evaporated and move toward the glass tube wall. When approaching the glass tube wall, tungsten vapor is cooled to about 800°C and combines with halogen atoms to form tungsten halides, such as tungsten iodide or tungsten bromide. Tungsten halides continue to move toward the center of the glass tube and return to the oxidized filament. Since tungsten halides are very unstable compounds, they will decompose into halogen vapor and tungsten again when heated, so that tungsten is deposited on the filament again to make up for the evaporated part. Through this regeneration cycle process, not only is the service life of the filament greatly extended, but the filament is also operated at a higher temperature, thereby achieving a higher color temperature and higher luminous efficiency.

[0004] Since halogen lamps generate a lot of heat and emit a full spectrum, that is, their spectrum includes the spectrum curves of ultraviolet light, visible light, and infrared light, they are widely applicable. However, they generate a lot of heat. If the high temperature cannot be effectively blocked, people are easily burned during use. If general heat insulation methods are used, such as glass fiber, it is not only not conducive to reducing the size of the equipment, but also complicated to assemble, resulting in increased costs and not conducive to promotion. Moreover, glass fiber is always at high temperatures, its life will be reduced, and it will form floating dust and pollute the medical environment, which is also not allowed. At the same time, its replacement is also very troublesome and requires professional personnel to replace it, which undoubtedly further increases the cost of the thermal therapy device. Summary of the invention

[0005] In view of this, the present invention provides a spectrum thermal therapy device with a ventilation and cooling system that is conducive to solving the above-mentioned problems and meeting various needs of users.

[0006] A spectrum thermotherapy device with a ventilation and cooling system comprises a barrel, a light source assembly arranged in the barrel, an air guide assembly arranged outside the light source assembly, a filter assembly arranged in the light emitting direction of the light source assembly, and an air suction assembly arranged in the backlight direction of the light source assembly. The light source assembly comprises a halogen lamp. The air guide assembly comprises an assembly barrel spaced apart from the barrel, and an air guide roll arranged at one end of the assembly barrel close to the filter assembly. The halogen lamp is accommodated in the assembly barrel. The air guide roll is a cone-shaped structure. On a cross section perpendicular to the central axis of the assembly barrel, the contour line of any cross section of the air guide roll is a part of an involute. The air guide roll comprises a large diameter edge facing the assembly barrel, a small diameter edge facing away from the assembly barrel, a first end located inside, and a second end located outside. The outside of the large diameter edge close to the first end is in contact with or tangent to the inner edge of the assembly barrel. The air suction assembly is used to suck air into the barrel along the light emitting direction facing away from the light source assembly. The filter assembly is fixed on the barrel and comprises a shell fixedly connected to the barrel, and a plurality of air inlet channels are arranged on the edge of the shell.

[0007] Furthermore, the cylinder body and the assembling cylinder are coaxially arranged.

[0008] Furthermore, the wind guide roll is formed by winding a plate-shaped material, and the winding angle is greater than 360 degrees.

[0009] Furthermore, the air suction component is an air suction fan or a negative pressure device.

[0010] Furthermore, when the air suction component is an air suction fan, the winding direction of the air guide roll is the same as the rotation direction of the sucked airflow.

[0011] Furthermore, the edge where the large diameter side is located is spaced apart from the edge of the assembly tube, and the edge where the large diameter side is located abuts against the inner side of the edge of the assembly tube along the extension direction of the length of the tapered hypotenuse.

[0012] Furthermore, the inner side of the large diameter side close to the second end is spaced apart from the outer edge of the assembling tube.

[0013] Furthermore, the smallest circle of the edge where the small diameter side is located is equivalent to the inner diameter of the smallest inscribed circle of the multiple air inlet channels of the filter assembly.

[0014] Further, the first end is spaced apart from the second end and is spaced apart from the second end in a radial direction of the assembling cylinder.

[0015] Furthermore, the filter assembly also includes at least one filter disposed in the housing, and a cover body fixed on the housing, and the housing and the cover body are both annular.

[0016] Compared with the existing technology, the spectrum thermotherapy device with ventilation and cooling system provided by the present invention is provided with the filter assembly and the negative pressure assembly at both ends of the barrel, and the housing of the filter assembly is provided with a ventilation channel, so that when the negative pressure assembly sucks air, the cold air can be sucked from the filter assembly into the barrel. The barrel is provided with an air guide assembly, a halogen lamp is provided in the air guide assembly, and the air guide assembly includes an assembly barrel and an air guide roll spaced from the barrel, so that when the cold air is sucked from the filter assembly into the barrel, most of the cold air enters between the barrel and the assembly barrel, which is not only conducive to the heat dissipation of the barrel, but also conducive to blocking the heat emitted by the assembly barrel, so as to avoid the barrel heating up too high and hurting the user. For the cold air that inevitably enters the assembling cylinder, due to the existence of the air guide roll, the air guide roll is conical, and the air guide roll is an involute on any cross section perpendicular to the central axis of the assembling cylinder, the cold air entering the assembling cylinder is rotated, and then the rotating cold air will flow toward the air suction component close to the inner wall of the assembling cylinder under the action of centrifugal force, which can not only further reduce the temperature of the assembling cylinder, but also prevent the cold air from affecting the use of the halogen lamp, thereby achieving the purpose of cooling the cylinder without damaging the halogen lamp.

[0022] The specific embodiments of the present invention are further described in detail below. It should be understood that the description of the embodiments of the present invention herein is not intended to limit the protection scope of the present invention.

[0023] like Figures 1 to 5 As shown, it is a schematic diagram of the structure of a spectrum thermotherapy device with a ventilation and cooling system provided by the present invention. The spectrum thermotherapy device with a ventilation and cooling system includes a barrel 10, a light source assembly 20 arranged in the barrel 10, an air guide assembly 30 arranged outside the light source assembly 20, a filter assembly 40 arranged in the light emitting direction of the light source assembly 20, and an air suction assembly 50 arranged in the backlight direction of the light source assembly 20. It can be imagined that the spectrum thermotherapy device with a ventilation and cooling system also includes some other functional modules, such as assembly components, power supply modules, and electrical connection components, etc., which are well known to those skilled in the art and will not be described in detail one by one here.

[0024] The barrel 10 is used to accommodate and assemble the light source assembly 20, the air guide assembly 30, the filter assembly 40, and the air suction assembly 50, so its size and shape can be set according to actual needs. In the present embodiment, the barrel 10 is cylindrical and made of aluminum alloy. The axial ends of the barrel 10 are through holes, and the axial ends of the barrel 10 are respectively assembled with the filter assembly 40 and the air suction assembly 50, which will be described in detail below.

[0025] The light source assembly 20 includes a halogen lamp 21 and a lamp holder 22 for carrying the halogen lamp 21. The halogen lamp 21 itself is a prior art and will not be described here. When powered on, the halogen lamp 21 can emit light and radiate a large amount of heat, and its internal temperature can reach about 800°C. The heat will radiate outward, thereby heating the barrel 10 and the air guide assembly 30. It is conceivable that if the barrel 10 is not cooled, its temperature can reach more than 90°C, which may cause burns to the user during use. From another perspective, since the temperature of the lamp shell surface of the halogen lamp 21 is also as high as about 800°C, cold air cannot be blown directly, because the temperature difference between the inside and the outside is too large, which will cause the lamp shell to explode, thereby causing damage to the halogen lamp 21. Therefore, a contradiction is formed, that is, the barrel 10 needs to be cooled quickly, but the light source assembly 20 contained therein cannot be cooled. Of course, the light source assembly 20 should not be cooled either, because it needs to provide enough heat for thermal therapy. It is conceivable that in order to improve light extraction efficiency and fully utilize the light source, the light source assembly 20 further includes a reflector cup disposed outside the halogen lamp 21. The reflector cup itself is prior art and will not be described in detail herein.

[0026] The air guide assembly 30 includes an assembly tube 31 disposed inside the barrel 10, and an air guide roll 32 disposed at one end of the assembly tube 31. The diameter of the assembly tube 31 is smaller than the inner diameter of the barrel 10, so that the assembly tube 31 is spaced apart from the barrel 10. In order to facilitate assembly, the assembly tube 31 is coaxially arranged with the barrel 10, so that the assembly tube 31 and the barrel 10 are equally spaced apart, so that when the air suction assembly 50 is working, cold air can pass through the interval between the assembly tube 31 and the barrel 10, and then cool the barrel 10 to a temperature suitable for the user to touch. At the same time, due to the existence of the assembly tube 31, it can prevent the cold air from blowing directly on the halogen lamp 21 and causing damage to the halogen lamp 21. Therefore, the assembly tube 31 is not only used to assemble the halogen lamp 21, but also used to protect the halogen lamp 21 to avoid it being directly affected by cold wind. Therefore, the halogen lamp 21 is accommodated in the interior of the assembly tube 31. Preferably, the central axis of the halogen lamp 21 is coaxial with the central axis of the assembly tube 31. Such an arrangement also facilitates the air guide roll 32 to play a better role, which will be described in detail below. The assembly tube 31 is also a tubular tube with openings at both ends. The assembly method of the assembly tube 31 and the cylinder body 10 should be the existing technology, such as using connecting ribs, or annular assembly rings, etc., to space the assembly tube 31 and the cylinder body 10. It can be understood that in the process of introducing cold wind between the assembly tube 31 and the cylinder body 10, it is inevitable that cold wind will enter the assembly tube 31, unless the volume of the cylinder body 10 is made large enough, but this does not meet the requirements of industrial design, that is, it is not beautiful and economical. Therefore, in order to minimize the volume of the cylinder 10 and prevent cold air from entering the interior of the assembly cylinder 31 , the air guide roll 32 is provided at the air inlet end of the assembly cylinder 31 .

[0027] The wind guide roll 32 is a cone-shaped structure as a whole, that is, the wind guide roll 32 can be formed by winding a plate-like material, and the winding angle is greater than 360 degrees. As described below, the air suction assembly 50 can be an air suction fan or a negative pressure device, that is, it draws wind from one end of the filter assembly 40 to one end of the air suction assembly 50. When the air suction assembly 50 is an air suction fan, due to the rotation of the blades of the fan, the air flow sucked in is also rotating, so the rotation direction of the wind guide roll 32 should be the same as the rotation direction of the air flow sucked in. When the air suction assembly is a negative pressure device, it cannot rotate the air flow sucked in, and the wind guide roll 32 should rotate the air flow, because only when the air flow rotates can centrifugal force be generated, so that the sucked cold air leaves the halogen lamp 21 located on the central axis of the assembly tube 31, avoiding the cold air from affecting the halogen lamp 21 and causing it to explode and damage. In order to achieve the above purpose, on a cross section perpendicular to the central axis of the assembly tube 31, the contour line of any cross section of the air guide roll 32 is a part of an involute, such as Figure 4 As shown. The involute basically conforms to the rotation of the wind formed by the suction fan, and the involute is also conducive to quickly turning the non-rotating airflow into a rotating airflow. The wind guide roll 32 includes a large diameter edge 321 facing the assembly tube 31, a small diameter edge 322 facing away from the assembly tube 31, a first end 323 located on the inside, and a second end 324 located on the outside. Figure 3 As shown, the outer side of the large diameter edge 321 close to the first end 323 is in contact with or tangent to the inner edge of the assembly cylinder 31. In this embodiment, due to assembly reasons, the edge where the large diameter edge 321 is located is spaced apart from the edge of the assembly cylinder 31, but the edge where the large diameter edge 321 is located is in contact with the inner side of the edge of the assembly cylinder 31 along the extension direction of the length of the tapered hypotenuse. The inner side of the large diameter edge 321 close to the second end 323 is spaced apart from the outer edge of the assembly cylinder 31. The first end 323 and the second end 324 are spaced apart and the first end 323 and the second end 324 are spaced apart in the radial direction along the assembly cylinder 31, that is, the first end 323 and the second end 324 are not both located on one diameter of the assembly cylinder 31.

[0028] like Figure 2As shown, the smallest circle of the edge where the small diameter edge 322 is located is equivalent to the inner diameter of the smallest inscribed circle of the multiple air inlet channels 411 of the filter assembly 40 described below, so that the sucked cold air can enter as much as possible between the assembly cylinder 31 and the cylinder body 10. For a small amount of cold air entering the assembly cylinder 31, due to the presence of the air guide roll 32, the wind is rotated, so that under the action of centrifugal force, the cold air will rotate close to the inner wall of the assembly cylinder 31 and flow to one side of the air suction assembly 50, so as not to affect the halogen lamp 21, and further not to cause the halogen lamp 21 to explode and be damaged.

[0029] The filter assembly 40 is fixedly arranged at the end of the barrel 10 and is located in the light emitting direction of the light source assembly 20. The filter assembly 40 is used to filter out some wavelength bands of light according to actual needs and allow light of a certain wavelength band to pass through. Of course, it is conceivable that when light of different wavelength bands needs to pass through, the filter assembly 40 can be replaced. Figure 1 As shown, the filter assembly 40 includes a shell 41 fixedly connected to the barrel 10, at least one filter 42 arranged in the shell 41, and a cover 43 fixed to the shell 41. The shell 41 is an annular structure, and the filter 42 is arranged on the central through hole of the shell 41 to allow light to pass through. The structure and material of the filter 42 are prior art and are not described here. The filter 42 is clamped and fixed between the shell 41 and the cover 43. In order to allow light to pass through, the cover 43 is also annular, and is fixed to the shell 41 by fasteners such as screws. In order to allow cold air to enter the barrel 10 under the action of the air suction assembly 50, the edge of the shell 41 is provided with multiple air inlet channels 411. The presence of the air inlet channel 411 allows cold air to enter the barrel 10. In the process of cold air entering, it can also achieve a heat dissipation effect, because when the light emitted by the halogen lamp 21 passes through the filter 42, the filter 42 will also absorb a large amount of heat. If it is not dissipated in time, it will deform. It can be imagined that in order to further dissipate the heat of the filter 42, other heat dissipation components, such as water, are also provided in the filter assembly 40. Therefore, due to the presence of the air inlet channel 411, the periphery of the housing 41 has a plurality of heat dissipation fins, which can dissipate the heat of the filter 42.

[0030] The suction component 50 can be a suction fan or a negative pressure device. The suction fan or the negative pressure device itself is a prior art and will not be described in detail here. When the suction component 50 is a suction fan, it can be directly fixed to the end of the barrel 10 that is away from the light emitting direction of the light source assembly 20. When the suction component 50 is a negative pressure device, it may include a negative pressure pump, and a conduit fixedly connected to the negative pressure pump and one end of the barrel 10. The disadvantage of using a negative pressure device is that it is inconvenient to move and use, and the advantage is that the air volume can be adjusted. Of course, it can be imagined that the priority of the suction fan is that it is convenient to move and use, and the disadvantage is that the air volume is inconvenient to adjust.

[0031] Compared with the existing technology, the spectrum thermotherapy apparatus with ventilation and cooling system provided by the present invention is provided with the filter assembly 40 and the negative pressure assembly 50 at both ends of the barrel 10, and the housing 41 of the filter assembly 40 is provided with a ventilation channel 411, so that when the negative pressure assembly 50 sucks air, the cold air can be sucked from the filter assembly 40 into the barrel 10. The barrel 10 is provided with an air guide assembly 30, the air guide assembly 30 is provided with a halogen lamp 21, and the air guide assembly 30 includes an assembly barrel 31 and an air guide roll 32 spaced from the barrel 10, so that when the cold air is sucked from the filter assembly 40 into the barrel 10, most of the cold air enters between the barrel 10 and the assembly barrel 31, which is not only conducive to the heat dissipation of the barrel 10, but also conducive to blocking the heat emitted by the assembly barrel 31, so as to prevent the barrel 10 from heating up too high and hurting the user. For the cold air that inevitably enters the assembly cylinder 31, due to the existence of the air guide roll 32, the air guide roll 32 is conical, and the air guide roll 32 is an involute on any cross section perpendicular to the central axis of the assembly cylinder 31, the cold air entering the assembly cylinder 31 is rotated, and then the rotating cold air will flow toward the air suction component 50 close to the inner wall of the assembly cylinder 31 under the action of centrifugal force, thereby not only further reducing the temperature of the assembly cylinder 31, but also preventing the cold air from affecting the use of the halogen lamp 32, thereby achieving the purpose of cooling the cylinder body 10 without damaging the halogen lamp 21.

[0032] The above are only preferred embodiments of the present invention and are not intended to limit the protection scope of the present invention. Any modification, equivalent substitution or improvement within the spirit of the present invention is included in the scope of the claims of the present invention.
