In addition, the existing heating mechanism also has the problem of direct infrared light. Utility Model Content

The drawings provide preferred embodiments of the present invention. However, the present invention can be implemented in many other different forms and is not limited to the embodiments described herein.

[0028] like Figure 1-2 As shown, in one embodiment of the heating mechanism, the heating mechanism comprises a reflective cover 1, a reflective heating plate and a reflective plate 3. The reflective cover 1 has a cover bottom surface 11 and a light outlet 12 away from the cover bottom surface 11. One side of the luminescent heating plate 2 is mounted on the cover bottom surface 11, and the other side faces the light outlet 12. The side of the luminescent heating plate 2 facing the light outlet 12 can emit infrared light. The reflective plate 3 is located between the luminescent heating plate 2 and the light outlet 12, and is used to block part of the infrared light from being directly emitted from the light outlet 12.

[0029] In this embodiment, the luminous heating of the heating mechanism of this embodiment is a luminous heating plate 2 with a plate-like structure. Unlike a traditional heating rod, it will not cause heat accumulation between the bottom surface 11 of the cover and the luminous heating plate 2. In addition, the heating mechanism of this embodiment is also provided with a reflective plate 3, which can prevent infrared light from being directly emitted, thereby solving the technical problems of high temperature in the reflective cover 1 of the existing heating mechanism and the presence of direct infrared light.

[0030] In an embodiment of the heating mechanism, the extending direction of the reflective plate 3 is parallel to the extending direction of the luminous heating plate 2 .

[0031] In this embodiment, by making the extension direction of the reflective plate 3 parallel to the extension direction of the luminescent heating plate 2, the covering relationship between the reflective plate 3 and the luminescent heating plate 2 can be better coordinated, thereby better preventing the infrared light emitted by the luminescent heating plate 2 from being directly emitted from the light outlet 12.

[0032] In an embodiment of the heating mechanism, the reflective plate 3 is slidably connected to the reflective cover 1 so that the position of the reflective plate 3 relative to the reflective cover 1 can be adjusted.

[0033] It is understandable that when the heating mechanism is used in different scene environments, the heating mechanism as a whole will generally be configured to be relatively rotatable and can be rotated arbitrarily to change the irradiation direction. In order to enable the reflector 3 to avoid direct radiation, the reflector 3 in this embodiment is configured to be slidable on the reflective cover 1, which can be convenient for the staff to adjust.

[0034] Specifically, the reflective plate 3 can be rotated in the reflective cover 1 in the following manner. In one embodiment of the heating mechanism, sliding holes 13 are provided on the side walls on opposite sides of the reflective cover 1, and the reflective plate 3 has protrusions 31 that are correspondingly penetrated through the sliding holes 13, and the reflective plate 3 is slidably connected to the reflective cover 1 through the protrusions 31.

[0035] In addition, in order to fix the reflector 3 to the reflector 1, a plurality of holes can be provided on the reflector 1, and the arrangement direction of these holes is the same as the extension direction of the slide hole 13, and the protrusion 31 is fixed to the reflector 1 by passing bolts. It can be understood that the portion of the protrusion 31 protruding from the slide hole 13 can be bent to fit onto the reflector 1.

[0036] In one embodiment of the heating mechanism, the reflective plate 3 is an arc-shaped plate, the concave surface of the arc-shaped plate faces the luminescent heating plate 2, the side of the reflective plate 3 opposite to the luminescent heating plate 2 is the reflective side, and the middle part of the luminescent side is concave in the direction away from the luminescent heating plate 2.

[0037] In this embodiment, by setting the reflector 3 into an arc-shaped structure, the direction of light can be changed, and the infrared light is not easily directly reflected back to the light-emitting heating plate 2, but is reflected onto the reflector 1.

[0038] In an embodiment of the heating mechanism, the shape of the sliding hole 13 is an arc shape matching the reflective plate 3 .

[0039] In this embodiment, by setting the shape of the sliding hole 13 to an arc shape, the sliding of the reflector 3 can be facilitated, so that the angle of the reflector 3 changes during the sliding process, so that the concave surface of the reflector 3 can always face the light-emitting heating plate 2.

[0040] In one embodiment of the heating mechanism, the luminous heating plate 2 includes a substrate, a heating wire and a coating. The substrate is installed on the bottom surface 11 of the cover. There are multiple heating wires, and they are all installed on the side of the substrate away from the bottom surface 11 of the cover. The coating is sprayed on the substrate and each heating wire. The coating between adjacent heating wires is recessed toward the substrate relative to the coating at the position of the heating wire.

[0041] In this embodiment, by setting a coating, near infrared can be absorbed to avoid harm to the patient. In addition, the substrate can supply energy to the heating wire, so that the heating wire can emit light, heat and infrared light. Compared with the heating rod, it can avoid heat accumulation in the reflective cover 1.

[0042] Specifically, in combination with the previous embodiment, when the light-emitting heating plate 2 is an arc-shaped structure, correspondingly, in an embodiment of the heating mechanism, a surface of one side of the substrate facing the light outlet 12 is an arc surface convex toward the light outlet 12, and each of the heating wires is installed at intervals on the arc surface of the substrate relative to the reflective plate 3. The specific effects have been described above and will not be repeated here.

[0043] In an embodiment of the heating mechanism, each heating wire is arranged in parallel along an extension direction of the substrate.

[0044] In this embodiment, specifically, referring to Figure 1-2 As shown, taking the number of heating wires as three as an example, the three heating wires correspond to Figure 2 The three positions indicated by A are inside, and it can be understood that Figure 2 The visible parts shown are all coatings. Two of the three heating wires are located at the two ends of the curved surface of the substrate, and the third heating wire is located in the middle of the curved surface of the substrate. Through such an arrangement, the characteristics of light irradiation in all directions can be better matched, and infrared light can be quickly dissipated, reducing internal heat accumulation, and improving efficiency and life.

[0045] The utility model also relates to a radiation warming device, comprising the heating mechanism in the foregoing embodiment.

[0046] By applying the heating mechanism in the previous embodiment, it is possible to avoid heat accumulation between the bottom surface 11 of the cover and the heating mechanism, thereby increasing the service life, and it is also possible to avoid direct radiation to the patient, thereby bringing a good treatment experience to the patient.

[0047] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, 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, they should be considered to be within the scope of this specification.

[0048] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the patent application. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
