[0038] As Figures 1 to 4 shown, a light-emitting structure 10 in an embodiment includes a light-diffusing component 100. The light-emitting structure 10 further includes a light-emitting element 200 and a mounting base 300. A mounting seat 110 and the light-emitting element 200 are both connected to the mounting base 300, and a light-diffusing element 120 is disposed between the light-emitting end of the light-emitting element 200 and a first light-transmitting portion 112.

[0039] Specifically, as Figures 5 to 7 shown, the light-diffusing component 100 includes a mounting seat 110 and a light-diffusing element 120. The mounting seat 110 is provided with a first light-transmitting portion 112, and the mounting seat 110 is provided with a first positioning portion 1162; the light-diffusing element 120 is provided with a second positioning portion 122 for positioning and mating with the first positioning portion 1162, and the light-diffusing element 120 is provided with a light-diffusing portion; when the first positioning portion 1162 and the second positioning portion 122 are positioned and mated, the light-diffusing portion blocks the first light-transmitting portion 112.

[0040] When the above light-emitting structure 10 is in use, the light of the light-emitting element 200 irradiates on the light-diffusing portion, and uniform light emission is observed at the light-diffusing portion through the first light-transmitting portion 112; further, since the light-diffusing element 120 is positioned and installed on the mounting seat 110 by positioning and mating the first positioning portion 1162 and the second positioning portion 122, the installation accuracy of the light-diffusing element 120 is relatively high at this time; furthermore, when the light-diffusing element 120 and the light-emitting element 200 are installed and arranged in cooperation, only the position of the mounting seat 110 needs to be adjusted or the mounting seat 110 needs to be modified and installed, and there is no need to perform additional adjustment and damage to the light-diffusing element 120. In this way, the light-diffusing element 120 can be protected from being damaged and affecting the light-homogenizing effect of the light-diffusing element 120; in addition, the assembly position of the light-diffusing element 120 and the first light-emitting hole is fixed. When the light-diffusing element 120 and the light-emitting element 200 are installed in cooperation, only the mounting seat 110 or the light-emitting element 200 needs to be adjusted, and the light-emitting effect of the light-emitting element 200 can be ensured.

[0041] Optionally, the light-diffusing element can be a light-diffusing plate, the light-diffusing portion is a structure in the light-diffusing plate that can achieve uniform light emission, and the light-diffusing plate can be a plate made of polypropylene material.

[0042] Specifically, the light-emitting component 200 can be directly connected to the mounting base 300, or indirectly connected to the mounting base 300. For example, the light-emitting component 200 can be directly connected to the mounting seat 110, and then the mounting seat 110 is connected to the mounting base 300. The specific connection method is set according to needs.

[0043] Specifically, the light-scattering part blocking the first light-transmitting part 112 can be complete blocking or partial blocking, and the specific blocking method is set according to needs.

[0044] On the basis of the above embodiments, in order to realize the assembly of the mounting seat 110 and the mounting base 300, the mounting base 300 is provided with a mounting through-hole, and the mounting seat 110 is installed in the mounting through-hole. When the mounting seat 110 is disposed in the mounting through-hole, due to different mounting methods, the light-emitting state of the light-scattering component 120 is also different; specifically, when the first light-transmitting part 112 is disposed outside the mounting through-hole, at this time, the light-scattering component 120 can directly present its own light-emitting state in the first through-hole; or, when the first light-transmitting part 112 is disposed between the mounting through-hole and the light-scattering component 120, at this time, the light-emitting state of the light-scattering component 120 can be presented through the mounting through-hole; or, the first light-transmitting part 112 is disposed in the area surrounded by the mounting through-hole, and at this time, the light-emitting state of the light-scattering component 120 can still be presented through the mounting through-hole.

[0045] On the basis of the foregoing embodiments, the mounting seat 110 passes through the mounting through-hole, and the mounting seat 110 is snap-connected to the mounting base 300. In this way, the mounting seat 110 is mounted on the mounting base 300 by snap connection, which is convenient for disassembly and installation. In this embodiment, in order to facilitate the snap-fit between the mounting seat 110 and the mounting base, guiding structures for guiding cooperation are provided on both the mounting seat 110 and the mounting base 300. Specifically, the guiding structure can be a guiding inclined surface.

[0046] Specifically, the mounting base 300 can be the refrigerating face mask of a refrigerator.

[0047] As Figure 7 shown, on the basis of any of the above embodiments, the light-emitting component 200 is provided with a plugging part 210 for plugging and cooperating with the mounting base 300. In this way, the assembly is realized by plugging and cooperating the light-emitting component 200 with the mounting base 300, which is convenient for disassembly and assembly; specifically, the plugging part 210 can be a plugging body, and the light-emitting component 200 is provided with a plugging hole for plugging and cooperating with the plugging body.

[0048] As Figure 2As shown, further, in order to improve the stability of the installation of the light-emitting component 200, specifically in this embodiment, the light-emitting structure 10 further includes a fastener. The insertion portion 210 is provided at one end of the light-emitting component 200, and the other end of the light-emitting component 200 is provided with a mounting hole 220 for the fastener to pass through. The mounting base 300 is provided with a mounting body, and the mounting body is provided with an internal threaded hole. One end of the light-emitting component 200 is in positioning cooperation with the mounting base 300 through the insertion portion 210. One end of the fastener is provided with an external threaded structure, and one end of the fastener passes through the mounting hole 220 and is in threaded connection with the internal threaded hole. At this time, one end of the light-emitting component 200 is in insertion cooperation with the mounting base 300, and the other end is mounted to the mounting base 300 by means of threaded connection through the fastener. In the traditional light-emitting device, both ends of the light-emitting component 200 are fixedly installed by means of snap connection. When disassembling and installing, it is necessary to deform both ends simultaneously, and the installation difficulty is relatively large and it is not easy to disassemble. In this embodiment, during installation, it is only necessary to insert one end of the light-emitting component 200 into the mounting base 300, and the other end is fixed to the mounting base 300 through the fastener, without deforming the light-emitting component 200, which is relatively convenient during both installation and disassembly.

[0049] Specifically, there are various ways to position and install the light-diffusing component 120 and the mounting seat 110. For example, it can be through the positioning cooperation between a positioning pin or positioning holes, etc. Specifically in this embodiment, the first positioning portion 1162 is a positioning hole, and the second positioning portion 122 is a positioning body that is in positioning cooperation with the positioning hole. At this time, positioning installation is carried out by inserting the positioning body into the positioning hole.

[0050] Specifically, the second positioning portion 122 may itself have a light-diffusing effect, or it may only play a positioning role without a light-diffusing effect.

[0051] Specifically in this embodiment, the positioning body is provided with a light-diffusing portion. The mounting seat 110 includes a mounting portion 116. The mounting portion 116 is provided with a positioning hole. The circumferential side wall of the mounting portion 116 is provided with a second light-transmitting portion and the second light-transmitting portion is arranged facing the first light-transmitting portion so that the light emitted by the light-emitting component 200 can be emitted to the first light-transmitting portion through the second light-transmitting portion. When the positioning body and the positioning hole are in positioning cooperation, the light-diffusing portion simultaneously blocks the first light-transmitting portion and the second light-transmitting portion. At this time, the light emitted by the light-emitting component 200 can be irradiated to the light-diffusing portion along the second light-transmitting portion and present the light-emitting state of the light-diffusing portion through the first light-transmitting portion 112.

[0052] Optionally, the first light-transmitting portion and the second light-transmitting portion may be light-transmitting holes or light-transmitting areas of a light-transmitting plate having a light-transmitting function. When the second light-transmitting portion is the light-transmitting area of a light-transmitting plate, the second light-transmitting portion should be provided at least on both sides opposite to the light-diffusing portion or the second light-transmitting portion is provided in the entire circumferential area of the mounting portion 116.

[0053] Such as Figure 5 andFigure 6 As shown, further, in this embodiment, the first light-transmitting part is the first light-transmitting hole 112, the second light-transmitting part is the second light-transmitting hole 1164 penetrating through the side wall of the positioning hole, and the second light-transmitting hole 1164 communicates with the first light-transmitting hole 112. At this time, the light emitted by the light-emitting part 200 can irradiate the light-diffusing part 120 along the second light-transmitting hole 1164 and present the light-emitting state of the light-diffusing part through the first light-transmitting part 112.

[0054] Specifically, the first light-transmitting hole 112 and the second light-transmitting hole 1164 can be completely formed by penetrating through the side wall of the mounting seat 110 at the mounting part 116.

[0055] As Figure 7 shown, after the positioning body and the positioning hole are positioned and installed, it is necessary to improve the stability of the light-diffusing part 120 installed on the mounting seat 110. Therefore, specifically in this embodiment, the light-diffusing part 120 includes a connecting body 124, one end of the positioning body is connected to the connecting body 124 and is arranged at an angle with the connecting body 124. When the other end of the positioning body is positioned and matched with the positioning hole, the connecting body 124 overlaps with the side wall of the mounting part 116. At this time, the light-diffusing part 120 is installed on the mounting seat 110 as a whole more stably; specifically, the situation where one end of the positioning body is arranged at an angle of 0° or 180° with the connecting body 124 is not included in the case where one end of the positioning body is arranged at an angle with the connecting body 124. In this embodiment, the connecting body 124 is perpendicular to the positioning body.

[0056] As Figure 7 shown, further, in order to further improve the stability of the light-diffusing part 120 after being positioned and installed on the mounting seat 110, the mounting seat 110 further includes a first clamping part 114, and the light-diffusing part 120 further includes a second clamping part 126 for clamping and cooperating with the first clamping part 114. When the first positioning part 1162 and the second positioning part 122 are positioned and matched, the first clamping part 114 and the second clamping part 126 are clamped and cooperated. At this time, through the cooperation of the first clamping part 114 and the second clamping part 126, the movement of the light-diffusing part 120 relative to the mounting seat 110 can be restricted, thereby improving the stability of the installation of the light-diffusing part 120. In this embodiment, in order to facilitate the clamping and cooperation between the mounting seat 100 and the light-diffusing part 120, a guiding structure for guiding cooperation is provided between the mounting seat 100 and the light-diffusing part 120. Specifically, the guiding structure can be a guiding inclined surface.

[0057] On the basis of any of the above embodiments, the light-emitting structure 10 further includes a lamp shade, and the lamp shade covers the first light-transmitting part 112. In this way, the lamp shade can play a protective role.

[0058] An embodiment also relates to a refrigeration device, including the light-emitting structure 10 in any of the above embodiments.

[0059] The light-emitting structure 10 can be installed on the refrigerating mask of the refrigerator. During use, the light of the light-emitting member 200 irradiates on the light-diffusing part, and uniform light emission is observed at the light-diffusing part through the first light-transmitting part 112. Further, since the light-diffusing member 120 is positioned and installed on the mounting base 110 through the positioning cooperation of the first positioning part 1162 and the second positioning part 122, the installation accuracy of the light-diffusing member 120 is relatively high at this time. Furthermore, when the light-diffusing member 120 and the light-emitting member 200 are installed and arranged in cooperation, only the position of the mounting base 110 needs to be adjusted or the mounting base 110 needs to be modified and installed, and there is no need to perform additional adjustment and damage to the light-diffusing member 120. In this way, the light-diffusing member 120 can be protected from being damaged and affecting the light-homogenizing effect of the light-diffusing member 120. In addition, the assembly position of the light-diffusing member 120 and the first light-emitting hole is fixed. When the light-diffusing member 120 and the light-emitting member 200 are installed and arranged in cooperation, only the mounting base 110 or the light-emitting member 200 needs to be adjusted, and the light-emitting effect of the light-emitting member 200 can be ensured.

[0060] As Figure 1 and Figure 2 shown, in this embodiment, the light-emitting member 200 is connected to the mounting base 300 and is spaced apart from the mounting base 110. The light-emitting member 200 faces the mounting base 110. The light-diffusing member 120 is inserted into the positioning hole. The light emitted by the light-emitting member 200 is emitted to the light-diffusing member 120 through the second light-transmitting hole 1164, and then reaches the first light-transmitting hole 112 through the light-diffusing member 120.

[0061] The technical features of the above embodiments can be combined arbitrarily. For the sake of concise description, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, it should be considered as the scope described in this specification.

[0062] The above embodiments only express several implementation manners of the present invention, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the invention patent. It should be noted that for those of ordinary skill in the art, without departing from the concept of the present invention, several deformations and improvements can still be made, and these all belong to the protection scope of the present invention. Therefore, the protection scope of the invention patent should be subject to the appended claims.
