In the description of the present application, "a plurality" means two or more, unless otherwise specifically defined.

[0040] In a first aspect, an embodiment of the present application provides a phototherapy lamp head 10. Please refer to Figures 1 to 5The phototherapy lamp head 10 includes a light source 11 and a first light filtering structure 12. The first light filtering structure 12 includes a heat sink 121, a first light-transmitting member 122, a support member 126, a second light-transmitting member 124 and a pressing member 125. The heat sink 121 is provided with a first through hole 1211 extending along a first direction. The hole wall of the first through hole 1211 is provided with a flange 1212. The X direction in the figure is the first direction. The first light-transmitting member 122 and the second light-transmitting member 124 are both located in the first through hole 1211, and the first light-transmitting member 122 and the second light-transmitting member 124 are spaced apart along the first direction. At least part of the support member 126 is clamped between the first light-transmitting member 122 and the second light-transmitting member 124. The support member 126 is an annular structure. The support member 126 and the first light-transmitting member 122 and the second light-transmitting member 124 are sealed to form a liquid storage chamber between the first light-transmitting member 122 and the second light-transmitting member 124. The liquid storage chamber is used to contain the light-filtering liquid. The pressing member 125 abuts against one end of the second light-transmitting member 124 away from the first light-transmitting member 122 , so that the first light-transmitting member 122 abuts against the flange 1212 ; the light source 11 is disposed at one side of the first through hole 1211 along the first direction and facing the first through hole 1211 .

[0041] The light source 11 is used to emit light to the first through hole 1211 , and the light is emitted from one side of the liquid storage cavity to the other side along a first direction. Optionally, the light source 11 is fixedly connected to the heat sink 121 .

[0042] The first light-transmitting member 122 and the second light-transmitting member 124 can both be transparent lenses that can transmit light. The first light-transmitting member 122 and the second light-transmitting member 124 are arranged opposite to each other and spaced apart to form a liquid storage cavity. The first light-filtering structure 12 is used to filter light. When light passes through the liquid storage cavity, the filter liquid filters harmful light. The filter liquid can filter out light of a specific wavelength band. Different types of solutions can be selected according to the filtered wavelength range, such as pure water, acid-base solution, or inorganic salt solution.

[0043] The first through hole 1211 in the heat sink 121 can limit the positions of the first light-transmitting member 122, the support member 126 and the second light-transmitting member 124 in the vertical first direction, so as to facilitate positioning and installation. It can be understood that the first through hole 1211 can be set as a circular hole or a polygonal hole. Optionally, the heat sink 121 is a cylindrical structure extending along the first direction.

[0044] The flange 1212 in the heat sink 121 is used to limit the position of the first light-transmitting member 122 along the first direction. It is understood that the flange 1212 can be annular, C-shaped, or a multi-segment structure arranged at intervals along the circumference of the first through hole 1211.

[0045] The support member 126 is an annular structure around the first direction, and the support member 126 spaces the first light-transmitting member 122 and the second light-transmitting member 124 apart. The support member 126 can be directly sealed to the first light-transmitting member 122 and the second light-transmitting member 124, or the support member 126 can be sealed to the first light-transmitting member 122 and the second light-transmitting member 124 through other structures. The support member 126 can be a rigid annular structure, or the support member 126 can be a sealing ring with two end faces abutting against each other.

[0046] The first light-transmitting member 122 and the second light-transmitting member 124 are made of transparent materials, which facilitate the transmission of light while isolating the filter liquid. Optionally, the first light-transmitting member 122 and the second light-transmitting member 124 are made of transparent high-transmission glass, and the thickness direction of the first light-transmitting member 122 and the second light-transmitting member 124 is the first direction.

[0047] It can be understood that the pressing member 125 can be an annular structure or a C-shaped structure around the first direction, so that light can pass through it.

[0048] When assembling, the second light-transmitting member 124, the support member 126, and the first light-transmitting member 122 are inserted into the first through-hole 1211 from the end of the first through-hole 1211 far from the flange 1212. Then, the pressing member 125 is used to squeeze the second light-transmitting member 124, and the first light-transmitting member 122 is squeezed onto the flange 1212 through the second light-transmitting member 124 and the support member 126. Then, the pressing member 125 is fixed to the heat sink 121 to keep it stable. Optionally, the pressing member 125 and the heat sink 121 are connected by bolts and screws.

[0049] The beneficial effect of this embodiment is that: The light therapy lamp head 10 provided by the embodiment of the present application includes a light source 11 and a first filter structure 12. A liquid storage cavity for accommodating the filter liquid is formed in the first filter structure 12, so that the first filter structure 12 can filter the light emitted by the light source 11. A flange 1212 is provided on the inner wall of the first through-hole 1211. After the second light-transmitting member 124, the support member 126, and the first light-transmitting member 122 are inserted into the first through-hole 1211, the flange 1212 can limit the position of the first light-transmitting member 122 in the first direction. Therefore, only one pressing member 125 is needed to limit the second light-transmitting member 124, with fewer parts and fewer parts to be assembled. The assembly process of the light therapy lamp head 10 is simpler, solving the technical problem of the complex assembly process of the light-transmitting lens in the prior art.

[0050] Furthermore, due to the setting of the support member 126, it is clamped between the first light-transmitting member 122 and the second light-transmitting member 124. Therefore, when the pressing member 125 pushes the second light-transmitting member 124, the support member 126 and the first light-transmitting member 122 can be driven to move toward the flange 1212 together until they abut against the flange 1212, so that the first light-transmitting member 122 and the second light-transmitting member 124 are both limited on the two opposite sides along the first direction, effectively preventing them from moving. Furthermore, since the flange 1212 is the structure of the heat sink 121 itself and is integrally arranged with the heat sink 121, the two can be processed as a whole without the need for subsequent assembly, thereby avoiding assembly errors. Therefore, the positioning accuracy between the flange 1212 and the heat sink 121 is high, and the flange 1212 is used as the positioning basis of the first light-transmitting member 122, the second light-transmitting member 124 and the pressing member 125 in the first direction, which is conducive to improving the overall installation accuracy.

[0051] The pressing member 125 may be disposed between the flange 1212 and the light source 11, or may be disposed on a side of the flange 1212 away from the light source 11; Figure 3 , Figure 4 As shown, the pressing member 125 includes a first annular segment 1251 and a second annular segment 1252 arranged in sequence along the first direction. The first annular segment 1251 is arranged in the first through hole 1211 and abuts against the second light-transmitting member 124; the second annular segment 1252 is arranged outside the first through hole 1211 and abuts against and is fixed to the end face of one end of the heat dissipation member 121.

[0052] The first ring segment 1251 and the second ring segment 1252 are both arranged around the first through hole 1211. Optionally, the first ring segment 1251 and the second ring segment 1252 are annular structures. The second ring segment 1252 is an annular structure and has an inner diameter equal to that of the first ring segment 1251 to ensure light transmission.

[0053] The pressing member 125 is connected to the heat sink 121 through the second annular segment 1252. Optionally, the second annular segment 1252 can be fixed to the heat sink 121 by passing a bolt through the second annular segment 1252 and the heat sink 121. The beneficial effects of this embodiment are as follows: the first annular segment 1251 is arranged in the first through hole 1211, and the first through hole 1211 can provide radial positioning for the first annular segment 1251, so as to facilitate the positioning of the pressing member 125; the second annular segment 1252 is arranged outside the first through hole 1211, so as to facilitate the connection with the heat sink 121, and the second annular segment 1252 abuts against the end surface of one end of the heat sink 121 to limit the position in the first direction.

[0054] In some embodiments, Figure 2 , Figure 3As shown, the heat dissipation member 121 is made of a heat-conducting material. A plurality of second through holes 1214 extending in the first direction are formed in the heat dissipation member 121. The plurality of second through holes 1214 are arranged around the first through hole 1211. The light source 11 is disposed on a side of the flange 1212 away from the pressing member 125. The phototherapy lamp head 10 further includes a heat insulation plate 13. The heat insulation plate 13 is connected to the heat dissipation member 121. The heat insulation plate 13 is an annular structure around the axis of the first through hole 1211. The heat insulation plate 13 abuts against an end of the second annular section 1252 away from the first annular section 1251. A positive projection of the second through hole 1214 on a plane where the heat insulation plate 13 is located is within the heat insulation plate 13.

[0055] The outer ring surface of the second annular section 1252 is located between the second through hole 1214 and the first through hole 1211 in a direction perpendicular to the first direction; Optionally, the outer diameter of the heat insulation plate 13 is greater than the outer diameter of the heat dissipation member 121. Optionally, the second through hole 1214 is not communicated with the liquid injection hole 1213. The length direction of the cross section of each second through hole 1214 is arranged along the radial direction of the first through hole 1211, so that the heat dissipation member 121 between adjacent second through holes 1214 forms a sheet structure.

[0056] Optionally, the heat insulation plate 13 is made of a heat insulation material; The heat insulation plate 13 can be fixed to the heat dissipation member 121 by screwing a bolt through the heat insulation plate 13 and the heat dissipation member 121.

[0057] The beneficial effects of this embodiment are as follows: Setting the heat dissipation member 121 as a heat-conducting material can improve the heat conduction efficiency, quickly conduct the heat of the filtering liquid and the heat conducted by the light source 11, and improve the heat dissipation effect of the phototherapy lamp head 10; The second through hole 1214 can increase the heat dissipation area of the heat dissipation member 121 and improve the heat dissipation effect; The second through hole 1214 extends in the first direction, which can directly discharge the hot air from the heat dissipation member 121 to achieve rapid heat dissipation. Due to the arrangement of the second through hole 1214, the heat is concentrated and flows out from the end of the heat dissipation member 121 away from the light source 11 and flows to the affected area. Setting the heat insulation plate 13 can block the hot air flowing from the second through hole 1214 of the heat dissipation member 121 to the affected area and direct the hot air to the surroundings; And the heat insulation plate 13 abuts against the second annular section 1252, so that the heat insulation plate 13 is spaced from the end surface of the heat dissipation member 121, avoiding the heat insulation plate 13 blocking the second through hole 1214 and resulting in the heat not being dissipated in time. The heat insulation plate 13 can also reduce the heat conducted by the pressing member 125 to it; The heat insulation plate 13 abuts against the second annular section 1252, which can reduce the gap between the heat insulation plate 13 and the second annular section 1252, reduce the hot air flowing from between the heat insulation plate 13 and the second annular section 1252 to the affected area, and slow down the influence of the hot air on the affected area.

[0058] In some embodiments, such as Figure 3 、 Figure 4As shown, a liquid injection hole 1213 is provided in the heat dissipation member 121, and the liquid injection hole 1213 communicates with the first through hole 1211; a third through hole 1261 communicating the liquid injection hole 1213 with the liquid storage cavity is provided in the support member 126.

[0059] The liquid injection hole 1213 is arranged at an angle with the first through hole 1211. One end of the liquid injection hole 1213 communicates with the first through hole 1211, and the other end of the liquid injection hole 1213 is arranged on the outer wall of the heat dissipation member 121. Optionally, the liquid injection hole 1213 is perpendicular to the first through hole 1211. The first light filtering structure 12 further includes a sealing plug adapted to the liquid injection hole 1213. The sealing plug is arranged in the liquid injection hole 1213 and is in interference fit with the liquid injection hole 1213, which is convenient for opening or closing the liquid injection hole 1213.

[0060] Both ends of the third through hole 1261 are arranged on the inner ring surface and the outer ring surface of the support member 126 respectively. Optionally, the third through hole 1261 is perpendicular to the first through hole 1211; the light filtering liquid can be injected into the liquid storage cavity through the liquid injection hole 1213 and the third through hole 1261.

[0061] The beneficial effects of this embodiment are as follows: By providing the liquid injection hole 1213 and the third through hole 1261, the light filtering liquid can be injected after the liquid storage cavity is assembled, which is convenient for operation; moreover, the liquid storage cavity can be filled with the light filtering liquid through the liquid injection hole 1213 and the third through hole 1261, improving the filtering effect on harmful light.

[0062] In some embodiments, as Figure 3 、 Figure 4 shown, the first light filtering structure 12 further includes a sealing member 123. The sealing member 123 includes a first sealing ring 1231 and a second sealing ring 1232 arranged in sequence along the first direction. A first annular groove 12311 is provided on the inner wall of the first sealing ring 1231, and the edge of the first light transmitting member 122 is embedded in the first annular groove 12311; a second annular groove 12321 is provided on the inner wall of the second sealing ring 1232, and the edge of the second light transmitting member 124 is embedded in the second annular groove 12321. The first sealing ring 1231 and the second sealing ring 1232 are respectively in sealing contact with the support member 126.

[0063] Optionally, the first light transmitting member 122 is in sealing contact with the hole wall of the first through hole 1211 through the first sealing ring 1231, and the second light transmitting member 124 is in sealing contact with the hole wall of the first through hole 1211 through the second sealing ring 1232.

[0064] The support member 126 is clamped between the first sealing ring 1231 and the second sealing ring 1232. The two ends of the first sealing ring 1231 in the first direction are respectively abutted against the flange 1212 and the support member 126, so as to seal between the support member 126 and the first sealing ring 1231. The first light-transmitting member 122 abuts against the two ends of the first annular groove 12311 in the first direction; optionally, the first annular groove 12311 is provided in the middle of the first sealing ring 1231.

[0065] The two ends of the second sealing ring 1232 in the first direction are respectively abutted against the support member 126 and the pressing member 125, so as to seal between the support member 126 and the second sealing ring 1232. The second light-transmitting member 124 abuts against the two ends of the second annular groove 12321 in the first direction; optionally, the second annular groove 12321 is provided in the middle of the second sealing ring 1232.
