[0030] The head light therapy device provided by the embodiments of the present application. As shown in the drawings, Figures 1 to 3As shown, the head light therapy device comprises a gas supply assembly, a head wearing assembly 2, and a first noise reduction structure 3. The gas supply assembly comprises at least a gas supply pipeline 1. The head wearing assembly 2 comprises a shell 21 capable of being worn on the head and a light emitting element (not shown in the figure) provided on the shell 21, the light emitting element being used to emit near-infrared light to the head, an inner part of the shell 21 forming a gas cavity 22 for transmitting gas to the head, and the gas supply pipeline 1 being used to supply gas to the gas cavity 22. The first noise reduction structure 3 is provided on an inner wall of the gas supply pipeline 1 and / or an inner wall of the gas cavity 22, and an inner part of the first noise reduction structure 3 forms a porous structure.

[0031] Exemplarily, the gas supply assembly can supply cold gas into the gas cavity to achieve a better cooling effect. In other embodiments, the gas supply assembly can also supply normal-temperature gas into the gas cavity, and the cooling effect can be achieved through the exchange of a large amount of normal-temperature gas. The present application is described by taking an example of the gas supply assembly comprising a refrigeration device for delivering cold gas to the gas supply pipeline 1, but the present application is not limited thereto, and those skilled in the art can also make other designs of the gas supply assembly according to the needs to achieve the purpose of cooling through ventilation. Exemplarily, the refrigeration device can be a compressor, and the refrigeration device transmits cold gas to the gas supply pipeline 1 after manufacturing the gas, and then transmits the gas into the gas cavity 22 of the shell 21 through the gas supply pipeline 1, and then transmits the gas to the head through the gas cavity 22 to achieve the effect of cooling the head, improve the comfort of the subject during light therapy, and thus further improve the treatment effect.

[0032] When it is necessary to increase the ventilation volume to achieve a better cooling effect for the head of the subject, the ventilation volume can be adjusted by adjusting the working state of the refrigeration device, so as to better cool the head of the subject. The present application adopts the first noise reduction structure 3 provided on the inner wall of the gas supply pipeline 1 and / or the inner wall of the gas cavity 22, which can especially solve the problem of increased noise caused by large ventilation volume, so as to achieve the effect of better cooling the head of the subject while reducing the noise around the head of the subject.

[0033] The shell 21 described above can be arranged corresponding to at least part of the head, for example, can be arranged corresponding to part of the brain of the head, or can be arranged corresponding to the whole head. Exemplarily, as shown in Figure 1 and Figure 2 The shell 21 shown in the figure is a shell 21 arranged corresponding to the whole head.

[0034] An inner side surface of the shell 21 can be provided with a gas outlet hole in communication with the gas cavity 22, and the gas cavity 22 discharges gas to the head of the subject through the gas outlet hole to achieve the purpose of cooling the head of the subject.

[0035] The first noise reduction structure 3 described above is arranged on the inner wall of the gas cavity 22, and can cover the inner wall of the gas cavity 22 in a paving manner, or can be arranged in adhesion to part of the inner wall of the gas cavity 22. The present application does not make specific limitations in this regard, and can achieve the purpose of absorbing noise through the porous structure of the first noise reduction structure 3.

[0036] The first noise reduction structure 3 described above can be made of any one of materials such as ethylene-propylene-diene rubber, silica gel, and polyurethane. Specifically, it can be made into a loose porous sound-absorbing structure, for example, a tubular structure of foamed rubber formed by using ethylene-propylene-diene rubber as a base material. The tubular structure can better adhere to the inner wall of the gas supply pipeline 1, so as to further improve the noise reduction effect of the first noise reduction structure 3.

[0037] The first noise reduction structure 3 described above can be made of a heat insulation material. In the case where the gas supplied by the gas supply pipeline 1 is cold air, the first noise reduction structure 3 made of a heat insulation material can better maintain the temperature of the cold air, so as to achieve the purpose of heat preservation for the gas.

[0038] The porous structure described above comprises a plurality of noise reduction holes, which are independent of each other, so as to achieve better noise reduction effect and the purpose of heat preservation for the gas.

[0039] By arranging the first noise reduction structure 3 on the inner wall of the gas supply pipeline 1 and / or the inner wall of the gas cavity 22, the present application can absorb the noise generated by the flow of the gas, so as to reduce the noise generated by the head cooling through gas ventilation. When the first noise reduction structure 3 is arranged on the inner wall of the gas supply pipeline 1, it can effectively reduce the noise generated when the gas supply pipeline 1 supplies gas to the gas cavity 22. When the first noise reduction structure 3 is arranged on the inner wall of the gas cavity 22, it can effectively reduce the noise generated by the impact, friction or vibration of the gas with the inner wall of the cavity after the gas enters the gas cavity 22. Thus, the noise level of the environment around the head of the object can be significantly reduced according to the arrangement position of the first noise reduction structure 3. Especially in the scene where it is necessary to increase the ventilation amount for better cooling of the head of the object, the better noise reduction effect can be achieved when a large amount of gas is introduced, so that the object can better receive light therapy and the comfort of the object during light therapy can be improved.

[0040] In some embodiments, when the first noise reduction structure 3 is arranged on the inner wall of the gas cavity 22, the first noise reduction structure 3 is arranged in a staggered manner with the light emitting member.

[0041] In this way, the first noise reduction structure 3 can be avoided from shielding the near-infrared light emitted by the light emitting member as much as possible, so as to ensure that more near-infrared light can be irradiated to the head, thereby ensuring the light therapy effect.

[0042] Optionally, the first noise reduction structure 3 can be arranged corresponding to the area between the adjacent light emitting members, so as to reduce the noise generated by the airflow as much as possible while ensuring the light treatment effect.

[0043] In some other embodiments, the first noise reduction structure 3 can be made of a light-transmitting material, in which case the first noise reduction structure 3 can be arranged corresponding to at least part of the light emitting members, so that the near-infrared light emitted by the light emitting members can be irradiated to the head through the light-transmitting first noise reduction structure 3, achieving the purpose of ensuring the light treatment effect while reducing the noise.

[0044] In some embodiments, as shown in Figure 1 and Figure 3 , the first noise reduction structure 3 is configured in a layer structure, and the first noise reduction structure 3 is arranged covering the inner wall of the gas supply pipeline 1; or, the first noise reduction structure 3 is configured in a layer structure, and the first noise reduction structure 3 is arranged corresponding to the inner wall of the local gas supply pipeline 1.

[0045] In this way, through the layer structure of the first noise reduction structure 3, the contact area between the first noise reduction structure 3 and the gas supply pipeline 1 can be increased as much as possible on the basis of reducing the space occupation, so that the gas can be in contact with the first noise reduction structure 3 more, and the noise generated by the gas flow can be absorbed through the porous structure of the first noise reduction structure 3.

[0046] When the first noise reduction structure 3 covers the inner wall of the gas supply pipeline 1, the shape of the first noise reduction structure 3 can be adapted to the shape of the gas supply pipeline 1, for example, when the shape of the gas supply pipeline 1 is tubular, the first noise reduction structure 3 is also tubular, so as to ensure the fit degree of the first noise reduction structure 3 and the inner wall of the gas supply pipeline 1.

[0047] When the first noise reduction structure 3 is arranged corresponding to the inner wall of the local gas supply pipeline 1, the shape of the first noise reduction structure 3 can be long strip-shaped, and the long strip-shaped first noise reduction structure 3 can be arranged along the circumferential direction of the gas supply pipeline 1 at intervals, and the length direction of the first noise reduction structure 3 is the same as the axial direction of the gas supply pipeline 1. Of course, the first noise reduction structure 3 can also have other shapes, such as V-shaped, cross-shaped, etc., which are not limited in the present application.

[0048] In some embodiments, the gas supply pipeline 1 is used to provide cold air to the gas cavity 22, so as to cool the head more quickly during light treatment. In this way, the cold air can be provided to the gas cavity 22 through the gas supply pipeline 1, so as to achieve the purpose of cooling the head more quickly, and further improve the comfort of the subject.

[0049] The cold air can be temperature-adjustable air obtained by refrigeration of a refrigeration device, and the temperature thereof can be controlled in a temperature range that can effectively cool the head of the subject without excessively stimulating the head of the subject, so as to further improve the comfort of the subject and increase the treatment compliance of the subject.

[0050] In some embodiments, the outer surface and / or the inner surface of the first noise reduction structure 3 are configured as closed surfaces wrapping the porous structure. In this way, the porous structure inside the first noise reduction structure 3 can be isolated from the external environment through the closed surfaces, so as to improve the noise reduction effect of the first noise reduction structure 3, and the cold air delivered through the first noise reduction structure 3 can be better insulated, thereby improving the cooling effect on the head of the subject. For example, as shown in Figure 1 and Figure 3 As shown, the outer surface and the inner surface of the first noise reduction structure 3 are both configured as closed surfaces wrapping the porous structure, so as to achieve a better insulation effect.

[0051] The closed surface can be understood as a surface without holes, and the outer surface of the closed surface can be a smooth surface. The smooth inner surface of the first noise reduction structure 3 can reduce the resistance and loss to the air speed, and the smooth outer surface of the first noise reduction structure 3 can increase the adhesion to the gas channel 22.

[0052] In some embodiments, the first noise reduction structure 3 is configured as a tubular shape, and the two ends of the first noise reduction structure 3 are connected to the inner wall of the gas supply pipeline 1 through an adhesive layer. While ensuring flexibility in use scenarios, the adhesive layer can stably mount the first noise reduction structure 3 in the gas supply pipeline 1, thereby increasing the mounting stability of the first noise reduction structure 3.

[0053] The thickness of the tubular first noise reduction structure 3 can be in the range of 5mm to 10mm, which can ensure the sound absorption effect of the porous structure while avoiding excessive thickness affecting the flow of the gas.

[0054] In some embodiments, as shown in Figures 1 to 4As shown, the head light therapy device further comprises an adapter 4, the gas supply pipeline 1 communicates with the gas channel 22 through the adapter 4, and the adapter 4 and / or the gas supply pipeline 1 is provided with a first bellmouth structure 5, the opening size of the first bellmouth structure 5 increases along the flow direction of the gas. And the cross-sectional area of the opening of the first bellmouth structure 5 is smaller than the cross-sectional area of the gas channel 22. In this way, the gas with a higher flow rate transmitted from the gas supply pipeline 1 can be gradually and slowly reduced in flow rate by the first bellmouth structure 5 before entering the gas channel 22 with a relatively larger cross-sectional area, so that greater noise caused by sudden changes in flow rate can be avoided, and the gas gradually and slowly reduced in flow rate can reduce turbulence and vortex caused by pressure changes when entering the gas channel 22 with a relatively larger cross-sectional area from the first bellmouth structure 5, and can reduce noise caused by sound wave reflection due to collision of the gas with the inner wall of the gas channel or other components in the gas channel, so that the subject can better receive light therapy and improve the comfort of the subject during light therapy.

[0055] The opening size of the above-mentioned first bellmouth structure 5 can gradually increase to gradually and slowly reduce the flow rate. Specifically, the first bellmouth has a certain length, which is designed to gradually increase, so that the flow rate of the gas entering the gas channel 22 is lower, and the noise generated by the collision of the gas with the inner wall of the channel, the vibration of the airflow, etc. is smaller. In a specific embodiment, the opening of the first bellmouth structure 5 can be configured as a tapered widening opening, which is beneficial to gently reduce the speed of the airflow and further reduce noise.

[0056] In some embodiments, the two ends of the above-mentioned adapter 4 can be connected to the gas channel 22 and the gas supply pipeline 1 respectively by a detachable connection mode, and specifically can adopt a plug-in connection mode to achieve the purpose of facilitating disassembly and assembly of the adapter 4.

[0057] In some embodiments, when the first bellmouth structure 5 is formed on both the adapter 4 and the gas supply pipeline 1, the first bellmouth structure 5 on the gas supply pipeline 1 can be located above the first bellmouth structure 5 on the adapter 4, and the maximum diameter of the first bellmouth structure 5 on the gas supply pipeline 1 is smaller than the minimum diameter of the first bellmouth structure 5 on the adapter 4, so that the gas can be discharged into the gas channel 22 along the two first bellmouth structures 5 with gradually increasing diameters, to achieve the purpose of further slowing down the airflow speed to better reduce noise. In other embodiments, the first bellmouth structure 5 can be formed on the gas supply pipeline 1 alone.

[0058] In some embodiments, as shown in FIG. 6, the adapter 4 is provided with a second bellmouth structure 6, and the second bellmouth structure 6 is located above the first bellmouth structure 5. The opening size of the second bellmouth structure 6 gradually increases along the flow direction of the gas. The cross-sectional area of the opening of the second bellmouth structure 6 is smaller than the cross-sectional area of the gas channel 22. In this way, the gas with a higher flow rate transmitted from the first bellmouth structure 5 can be gradually and slowly reduced in flow rate by the second bellmouth structure 6 before entering the gas channel 22 with a relatively larger cross-sectional area, so that greater noise caused by sudden changes in flow rate can be avoided, and the gas gradually and slowly reduced in flow rate can reduce turbulence and vortex caused by pressure changes when entering the gas channel 22 with a relatively larger cross-sectional area from the second bellmouth structure 6, and can reduce noise caused by sound wave reflection due to collision of the gas with the inner wall of the gas channel or other components in the gas channel, so that the subject can better receive light therapy and improve the comfort of the subject during light therapy. Figure 1As shown, the first horn structure 5 at least partially extends into the shell 21. In this way, the gas discharged by the first horn structure 5 can directly enter the gas cavity 22, avoiding collision with more contact surfaces, and further reducing the noise generated by the gas during transportation.

[0059] As shown, the first horn structure 5 at least partially extends into the shell 21. In this way, the gas discharged by the first horn structure 5 can directly enter the gas cavity 22, avoiding collision with more contact surfaces, and further reducing the noise generated by the gas during transportation.

[0060] In some embodiments, as shown in Figure 1 , Figure 2 As shown, the shell 21 further forms an air inlet cavity 23, the gas supply pipeline 1 is connected to the gas cavity 22 through the air inlet cavity 23, the air inlet cavity 23 forms a second horn structure 24, and the opening size of the second horn structure 24 increases along the flow direction of the gas.

[0061] In this way, the second horn structure 24 can further slow down the speed of the gas flow transported to the gas cavity 22, so as to reduce the noise generated by the high-speed fluid impacting the gas cavity 22, further achieving the purpose of noise reduction, so that the subject can better receive light treatment, and the comfort of the subject during light treatment is improved.

[0062] The opening size of the second horn structure 24 can gradually increase to gradually slow down the gas flow speed and further reduce the noise generated by the gas flow. Specifically, the opening of the second horn structure 24 can also be configured as a tapered widening opening.

[0063] The top of the shell 21 can be upwardly protruding to form a protruding portion, the air inlet cavity 23 is formed on the protruding portion, the gas cavity 22 is located below the air inlet cavity 23, and the cross-sectional area of the gas cavity 22 is greater than that of the air inlet cavity 23, so that the gas can diffuse outward after entering the gas cavity 22 through the air inlet cavity 23, so as to quickly cool the head of the subject.

[0064] In some embodiments, as shown in Figure 1 , Figure 3 and Figure 4 As shown, the adapter 4 includes a first pipe segment 41 and a second pipe segment 42 connected to each other, the first noise reduction structure 3 is sleeved outside the first pipe segment 41, the first horn structure 5 is configured as the pipe opening of the second pipe segment 42, and the second pipe segment 42 at least partially extends into the shell 21.

[0065] In this way, the adapter 4 can be stably sleeved with the first noise reduction structure 3 through the first pipe segment 41 and stably connected with the shell 21 through the second pipe segment 42, and the pipe cavity of the first pipe segment 41 and the pipe cavity of the second pipe segment 42 can smoothly connect with the gas transmitted from the pipeline, which can not only stably transport the gas, improve the structural stability and the stability of gas transportation, but also avoid generating more noise in the connection process.

[0066] The axis of the first pipe segment 41 and the axis of the second pipe segment 42 can be collinear, so that the gas can flow in a straight line direction to further reduce the noise generated by the gas flow. Specifically, the first pipe segment 41 and the second pipe segment 42 have a certain length to slowly reduce the flow rate of the gas and prevent more noise from being generated.

[0067] The first noise reduction structure 3 can be made of a deformable material, and the first pipe segment 41 can deform the first noise reduction structure 3 by extruding the inner wall surface of the first noise reduction structure 3, so as to stably sleeve the first pipe segment 41 and the first noise reduction structure 3. Of course, the inner wall surface of the first noise reduction structure 3 can also form an annular recess, and the first pipe segment 41 can be embedded in the annular recess of the first noise reduction structure 3 to stably sleeve the first pipe segment 41 and the first noise reduction structure 3. The specific connection mode of the first pipe segment 41 and the first noise reduction structure 3 is not limited in the present application, as long as the stable sleeve connection can be achieved.

[0068] The head light therapy device can further include a mounting shell 9 arranged at the gas outlet of the gas supply pipeline 1, and the mounting shell 9 is used to stably mount the gas supply pipeline 1 on the shell 21. The first pipe segment 41 and the second pipe segment 42 can be connected through a mounting ring, and the mounting ring can be mounted on the mounting shell 9 to stably connect the adapter 4 and the gas supply pipeline 1.

[0069] The end of the gas supply pipeline 1 connected with the shell 21 can be sleeved with a fixing sleeve 10, and the fixing sleeve 10 is located in the mounting shell 9, so that the end of the gas supply pipeline 1 connected with the shell 21 can be stably mounted in the mounting shell 9.

[0070] In some embodiments, as shown in Figure 1 and Figure 2 The inside of the shell 21 further forms an air inlet cavity 23, the gas supply pipeline 1 is connected with the gas cavity 22 through the air inlet cavity 23, the air inlet cavity 23 forms a second horn structure 24, the opening size of the second horn structure 24 increases along the flow direction of the gas, and the lower end of the first horn structure 5 is located below the root of the second horn structure 24. The root of the second horn structure 24 can be understood as the place where the caliber of the second horn structure 24 is the smallest.

[0071] In this way, by arranging the lower end of the first trumpet structure 5 below the root of the second trumpet structure 24, the flow rate of the gas can be slowed down when passing through the first trumpet structure 5 and the second trumpet structure 24 in sequence and then entering the gas cavity 22, thereby further reducing the noise level of the ambient environment around the head of the subject.

[0072] The lower end of the first trumpet structure 5 can be arranged above the opening of the second trumpet structure 24, and the caliber of the first trumpet structure 5 at the joint with the second trumpet structure 24 is smaller than the caliber of the second trumpet structure 24, so that the first trumpet structure 5 can be stably inserted into the second trumpet structure 24 on the basis of slowing down the gas flow when passing through the first trumpet structure 5 and the second trumpet structure 24 in sequence. Preferably, the maximum cross-sectional area of the opening of the first trumpet structure 5 reaches the lower edge where the second trumpet structure 24 is connected to the gas cavity 22, so as to avoid more collisions between the gas delivered from the first trumpet structure 5 and the inner wall of the second trumpet structure 24, thereby causing more noise.

[0073] In some embodiments, as shown in Figure 3 and Figure 4 , the outer wall of the second pipe segment 42 is formed with an annular groove 43, and a sealing ring 6 is arranged in the annular groove 43, so that the second pipe segment 42 and the shell 21 can be better sealed and connected by the sealing ring 6. In this way, the sealing connection between the second pipe segment 42 and the shell 21 can be ensured, so as to avoid the leakage of gas at the connection between the second pipe segment 42 and the shell 21 and to avoid the generation of more noise.

[0074] In some embodiments, as shown in Figure 1 , Figure 3 and Figure 4 , the head light therapy device further comprises an air extraction pipeline 7, and the shell 21 is formed with a containing cavity 8 in which the light emitting element is arranged, and the air extraction pipeline 7 is in communication with the containing cavity 8, so as to cool the light emitting element by the air extraction pipeline 7.

[0075] In this way, the heat in the containing cavity 8 can be taken away by the air extraction pipeline 7, so as to cool the light emitting element, prolong the service life of the light emitting element, and further improve the cooling effect of the head.

[0076] The head light therapy device can further comprise an air extraction device in communication with the air extraction pipeline 7, for extracting the gas in the containing cavity 8. The air extraction device can be specifically an air extraction pump, and can also be other devices capable of extracting air, which are not limited in the present application.

[0077] The air extraction pipeline 7 can be made of soft material, so as to facilitate the movement and adjustment of the air extraction pipeline 7 and improve the convenience of use.

[0078] In some embodiments, a second noise reduction structure (not shown in the figure) can be arranged on the inner wall of the air exhaust pipeline 7, and a porous structure is formed inside the second noise reduction structure.

[0079] In this way, the noise generated by the gas flow in the air exhaust pipeline 7 can be absorbed by the second noise reduction structure, further reducing the noise level of the environment around the head of the subject, and improving the comfort of the subject during light treatment.

[0080] The above-mentioned second noise reduction structure can be arranged corresponding to the inner wall of part of the air exhaust pipeline 7, or can cover the inner wall of the air exhaust pipeline 7, and the present application does not make specific limitations thereon, as long as the purpose of absorbing noise through the porous structure inside the second noise reduction structure can be achieved.

[0081] The above-mentioned second noise reduction structure can be made of the same structure and / or material as the first noise reduction structure 3, for example, both made of ethylene-propylene-diene rubber material, or can be made of different structures and / or materials, and the present application does not make specific limitations thereon.
