Abstract
Description
Technical Field
[0001] The present application relates to a small LED308 phototherapy device, and more particularly to a heat dissipation irradiation structure that can be integrated into a phototherapy rod, and belongs to the field of ultraviolet phototherapy technology. Background Art
[0002] Common treatments for vitiligo and psoriasis include drug therapy, physical therapy and surgical treatment. The most widely used of these is physical therapy. The most commonly used physical therapy is ultraviolet irradiation with a wavelength of 308nm. The principle is to use high-energy, short-wavelength 308nm ultraviolet rays to irradiate the patient's skin, which can restore the activity of melanocytes and promote melanin production, thereby effectively reducing the area of white spots and making the color of white spots gradually approach normal skin color.
[0003] According to the different light sources, 308nm UVB phototherapy is divided into 308nm excimer laser, 308nm quasi-beam, and 308nm LED light. The principle of 308nm excimer light / laser is that inert gas atoms produce high-energy ultraviolet light (excimer light) under the excitation of excimers, and 308nm LED light uses UVB LED to emit ultraviolet light with a peak wavelength of 308nm. Compared with 308 excimer light and 308 excimer laser, LED 308 has obvious advantages in terms of safety of use, light source life, consumables, maintenance, and environmental impact.
[0004] At present, LED308 ultraviolet light therapy devices are often used for the precise treatment of vitiligo and psoriasis in small areas such as hands and feet. Among them, miniaturized and portable LED308 ultraviolet light therapy devices are very popular.
[0005] Among them, a known portable ultraviolet therapy device (publication number CN210992644U) is provided with a heat dissipation component on the back of the irradiator, and the heat dissipation component includes heat dissipation fins and a heat dissipation fan. After the heat dissipation fan is started, the heat emitted by the heat dissipation fins can be blown out from the grille opening on the side of the radiator shell. Since the heat dissipation component and the irradiator are arranged as a whole in the treatment head, the volume and weight of the treatment head will be increased, which is not conducive to the compactness, lightness and uniformity of the product, and cannot meet the needs of use anytime and anywhere. At the same time, due to the limited heat dissipation space, the heat dissipation effect is poor, which affects the stability of the light source. Utility Model Content

[0015] In a possible implementation manner, the groove is a full-length groove, and the full-length groove is arranged in the middle of the heat sink perpendicular to the fin arrangement direction.
[0016] In a possible implementation, the heat dissipation holes have a preset pattern, and the preset pattern is formed by combining the shape arrangement of the multiple holes and the change of the hole diameter.

[0020] In a possible implementation, the sensing component is a capacitive touch sensor configured to be triggered by touching the affected area.

[0039] In order to make the purpose, technical solution and advantages of the embodiments of the present application clearer, the technical solution in the embodiments of the present application will be clearly and completely described below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.
[0040] In the related art, the irradiator of the small LED308 ultraviolet phototherapy product is connected to an electronic heat sink, but it is mostly concentrated at one end of the product to form a phototherapy head with a large volume and weight. On the one hand, it affects the degree of miniaturization and lightweight of the product. Although it can be carried, it is not suitable for phototherapy stick products, cannot meet the need of carrying it with you, cannot be used anytime and anywhere, and is not conducive to the uniformity of product configuration, affecting the convenience and comfort of handheld irradiation. On the other hand, the heat dissipation space of phototherapy stick products is further compressed. If the electronic heat sink in the prior art is still used, it will lead to poor heat dissipation effect, thereby affecting the stability of the light source.
[0041] In view of this, the embodiment of the present application provides a heat dissipation irradiation structure 10 that can be integrated into a phototherapy rod. By setting an irradiation unit 11 and a heat dissipation unit 12, and setting the heat dissipation unit 12 as a heat conductive plate 121, a flat heat pipe 122 and an air-cooled heat dissipation module 123, the flat heat pipe 122 is used to realize the front and rear layout of the irradiation unit 11 and the heat dissipation unit 12, which is suitable for the columnar shell 20 of the phototherapy rod. Based on the compact arrangement of the irradiation unit 11 and the heat dissipation unit 12 at the light emitting end 21 and the front end of the columnar shell 20, the product can be carried around and used anytime and anywhere. Moreover, the heat dissipation space of the heat dissipation unit 12 of the present embodiment corresponds to the inner cavity or at least the front half of the columnar shell 20, which alleviates the problem of poor heat dissipation caused by too small a heat dissipation space to a certain extent, and can also optimize the uniformity of product weight distribution, thereby improving the convenience and comfort of handheld operation; at the same time, the heat conduction plate 121 is in full surface contact with the heat dissipation unit 12, and then the heat is efficiently transferred to the air-cooled heat dissipation module 123 through the flat heat pipe 122 with a large heat conduction area and good effect, further ensuring the good heat dissipation effect after the product is miniaturized.
[0042] Reference Figures 1 to 4 As shown, the embodiment of the present application provides a heat dissipation irradiation structure 10 that can be integrated into a phototherapy rod, the phototherapy rod includes a columnar housing 20; the heat dissipation irradiation structure 10 includes:
[0043] An irradiation unit 11, the irradiation unit 11 is disposed at a light-emitting end 21 of the cylindrical housing 20, and the light-emitting end 21 is formed at one end of the length of the cylindrical housing 20;
[0044] The heat dissipation unit 12 is connected to the irradiation unit 11 and the two are sequentially arranged inside the columnar housing 20 along the length direction thereof;
[0045] The heat dissipation unit 12 includes a heat conducting plate 121, a flat heat pipe 122 and an air-cooled heat dissipation module 123. The air-cooled heat dissipation module 123 is arranged corresponding to the heat dissipation hole 20-1 of the columnar shell 20. The first surface of the heat conducting plate 121 covers and is connected to the back side of the irradiation unit 11. The flat heat pipe 122 has a first section and a second section arranged at an angle. The front surface of the first section of the flat heat pipe 122 is bonded to the second surface of the heat conducting plate 121, and the upper surface of the second section of the flat heat pipe 122 is bonded to the bottom surface of the air-cooled heat dissipation module 123.
[0046] In this embodiment, the heat conducting plate 121 is used to absorb the heat generated by the irradiation unit 11 when it is working, and is connected by surface covering, that is, the first surface of the heat conducting plate 121 is greater than or equal to the back of the irradiation unit 11, so that the irradiation heat can be taken away to the greatest extent. The flat heat pipe 122 is used to conduct the heat from the hot plate to the air-cooled heat dissipation module 123. Since the flat heat pipe 122 has a larger contact surface than the circular heat pipe, and is connected to the heat conducting plate 121 and the air-cooled heat dissipation module 123 by surface contact in the form of two sections, the thermal conductivity of the flat heat pipe 122 is improved, and the heat enters the air-cooled heat dissipation module 123 fully and quickly through the flat heat pipe 122; at the same time, the first section and the second section of the flat heat pipe 122 are set at an angle, and are also used to optimize the spatial layout of the irradiation unit 11 and the heat dissipation unit 12 to meet the needs of the phototherapy stick product, and because of the above-mentioned flat heat pipe 122 design, the adverse effects of miniaturization on the heat dissipation effect are avoided. The air-cooling heat dissipation module 123 and the heat dissipation hole 20 - 1 cooperate to utilize air flow to dissipate the heat inside the columnar housing 20 to the outside.
[0047] In one possible implementation, referring to Figure 1 and Figure 2 The air-cooled heat dissipation module 123 includes a heat sink 1231 and a heat dissipation fan 1232; two groups of heat dissipation holes 20-1 are symmetrically opened on opposite sides of the columnar shell 20, the heat dissipation fan 1232 is installed close to the first group of heat dissipation holes 20-1, and the heat sink 1231 is installed between the heat dissipation fan 1232 and the second group of heat dissipation holes 20-1.
[0048] When in use, low-temperature air is introduced from the first group of heat dissipation holes 20-1 by means of the heat dissipation fan 1232, flows through the fin gaps of the heat sink 1231, fully removes the heat on the fins to form high-temperature air, and then is discharged to the outside of the columnar shell 20 through the second group of heat dissipation holes 20-1.
[0049] In a possible implementation, a groove 1231 - 1 parallel to the arrangement direction of the fins is formed at one end of the heat sink 1231 away from the fins, and the groove 1231 - 1 is formed at least at one end of the heat sink 1231 close to the irradiation unit 11 .
[0050] Reference Figure 2-Figure 4 It can be understood that the heat sink 1231 corresponds to a conventional electronic radiator, having a row of parallel, spaced fins, one end of the fins being connected to a base plate. In this embodiment, by providing a groove 1231-1 on the base plate to accommodate the flat heat pipe 122, the second section of the flat heat pipe 122 can be in wrapped contact with the flat heat pipe 122, thereby further optimizing the heat transfer effect.
[0051] In a possible implementation, the groove 1231 - 1 is a segment groove 1231 - 1 opened near one end of the irradiation unit 11 , and the segment groove 1231 - 1 is arranged near one side of the heat dissipation fan 1232 .
[0052] The setting of the segment groove 1231-1 corresponds to Figure 2-4 The structure is shown, so that the second section of the flat heat pipe 122 can be placed in the segment groove 1231-1 near the bending part, firstly, it is in contact with the heat sink 1231 over a larger area on the side close to higher heat, and secondly, it provides enough space for the bent shape, so that the entire second section can be arranged flatly at the bottom of the heat sink 1231, which is conducive to the stable installation of the heat dissipation unit 12.
[0053] In a possible implementation, the groove 1231 - 1 is a full-length groove 1231 - 1 , and the full-length groove 1231 - 1 is disposed in the middle portion of the heat sink 1231 perpendicular to the fin arrangement direction.
[0054] The provision of the through-length groove 1231 - 1 is an alternative solution, which is not shown in the figure. It includes the design advantages of the segmented groove 1231 - 1 , and can also be in contact with the heat sink 1231 throughout its length, resulting in a larger heat transfer area.
[0055] In one possible implementation, referring to Figure 1 The heat dissipation hole 20 - 1 has a preset pattern, which is formed by combining the shape arrangement of the multiple holes and the change of the aperture.
[0056] The heat dissipation holes 20-1 are designed with a preset pattern, and the size and position of the holes can be used to guide the circulation of high-temperature air to achieve the best heat dissipation effect. For example, the heat distribution is related to the distance from the heat source, and more or larger heat dissipation holes 20-1 can be arranged on the side close to the heat source. In the design of the preset pattern, aesthetic factors can also be taken into account to enhance the beauty of the product.
[0057] In a possible implementation, the irradiation unit 11 includes an LED light source board 111 using a six-lamp array or a nine-lamp array, which is configured to obtain the following technical parameters:
[0058] Peak wavelength 308±2nm; irradiation intensity 20-60 mW / cm²; the stability of ultraviolet irradiation intensity is no more than 5%, and its non-uniformity is 33% or 26.6%.
[0059] When the LED light source assembly adopts an LED light source board 111 with a six-bead array, the light source driving part adopts a single-stage constant current boost method, and the six lamp beads are connected in three series and two in parallel; Figure 2 When the LED light source assembly adopts the LED light source board 111 with a nine-lamp array, the nine lamp beads are connected in three series and three parallels, and a single-stage constant current boost method is used.
[0060] In order to save costs, in this embodiment, the LED light source components can all use 308nm ultraviolet LEDs made of PW chips and driven by a boost constant current method. The LED light source board 111 design based on a six-bead array or a nine-bead array can achieve a minimum of 20mW / cm 2 , maximum 60mW / cm 2 Irradiation intensity, 20mW / cm 2 The low intensity is safer and more effective when used for children, 60mW / cm 2 The high intensity is a value that cannot be achieved by small-area treatment products on the market, which is conducive to achieving the expected treatment effect in a shorter irradiation time. In terms of light source uniformity, the maximum deviation of the simulated uniformity analysis of the prior art is 60%, and the uniformity is poor. However, the non-uniformity of the six-bead solution of this application is 33%, and the non-uniformity of the nine-bead solution is 26.6%, and the uniformity is significantly improved.
[0061] In one possible implementation, referring to Figure 1 The light emitting end 21 includes a light emitting port 21-1 opened at the end of the columnar shell 20, and the light emitting port 21-1 is configured to have an effective irradiation area of 2.5cm²±10%; a quartz glass 211 and a decorative sealing ring 212 are sequentially arranged between the light emitting port 21-1 and the LED light source board 111.
[0062] The above-mentioned LED light source board 111 of this embodiment is combined with the light output end 21 design, which can achieve an effective irradiation area of 2.5cm²±10%, which meets the requirements of small-area precision treatment; at the same time, the LED light source board 111 of this embodiment is combined with the above-mentioned heat dissipation unit 12 design, which can also achieve the stability of ultraviolet radiation intensity not more than 5%, which meets the technical standards.
[0063] Reference Figure 5-Figure 8In this embodiment, the light-transmitting glass mainly plays the role of protecting the light source, and its material can be quartz glass 211. Further preferably, the quartz glass 211 has a thickness of 1.5 mm and a distance of 1 mm from the surface of the light source. Furthermore, a decorative sealing ring 212 is placed between the glass and the light source, and the decorative sealing ring 212 not only plays a certain decorative role, but also can achieve a role of strengthening protection.
[0064] In one possible implementation, referring to Figure 5 and Figure 6 The light emitting end 21 further includes a plurality of sensing components 213 arranged around the light emitting port 21-1. Each sensing component 213 is independently connected to the input end of the control circuit. The output end of the control circuit is commonly associated with the irradiation unit 11. When the plurality of sensing components 213 located on the four sides of the light emitting end 21 are triggered at the same time, the irradiation unit 11 is started to irradiate, otherwise it is in a shutdown state.
[0065] Multiple sensing components 213 are used to trigger the light source to turn on. Only when the light emitting end 21 fully contacts the affected skin, that is, multiple contacts built around the light outlet 21-1 by the multiple sensing components 213 are triggered, will the irradiation treatment be started. This avoids erroneous operation caused by turning on the light source when the light outlet 21-1 is partially contacted, and can prevent the equipment from leaking ultraviolet light, thereby improving safety.
[0066] In one possible implementation, the sensing component 213 uses a capacitive touch sensor and is configured to be triggered by touching the affected area. More specifically, the sensing component 213 can be connected to the main control chip through a touch detection chip and a logic chip in sequence, and the main control chip is then controlled and connected to the LED light source board 111. Exemplarily, the touch detection chip, the logic chip and the main control chip can be jointly arranged on an integrated circuit board as a control unit 30 of the light therapy rod, which is used to intelligently adjust the working process and performance of the light therapy rod, not limited to the irradiation unit 11 and the heat dissipation unit 12.
[0067] Reference Fig. 9In a specific implementation, the sensing component 213 can use four capacitive touch sensors, which first detect the charge changes caused by the patient's skin contact through the four capacitive touch sensors, and then transmit them to the touch detection chip respectively; since the four capacitive touch sensors are placed in four directions of the light outlet 21-1, when a capacitive touch sensor detects that the patient is in contact with the light outlet 21-1, the corresponding channel of the touch detection chip will output a low-level signal. More specifically, the four capacitive touch sensors are touch detection sensor 1, touch detection sensor 2, touch detection sensor 3, and touch detection sensor 4, and the low-level signals output by them through the touch detection chip are touch detection output signal 1, touch detection output signal 2, touch detection output signal 3, and touch detection output signal 4, respectively; then, touch detection output signal 1 and touch detection output signal 2 are output through the signal output by the OR logic chip, and touch detection output signal 3 and touch detection output signal 4 are output through the OR logic chip, and the final detection signal obtained by OR operation is sent to the main control chip; only when the main control chip receives the low-level detection signal, the main control chip gives a signal to allow the light source to be turned on. If the sensor in any of the four directions is not in contact with the skin, the main control chip does not allow the light source to be turned on.
