Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of electromagnetic wave therapeutic apparatus structure, in particular to a reflective inner cover of an infrared therapeutic apparatus. Background Art
[0002] In order to gather heat, a reflective cover is designed on the lamp head of the therapeutic heating lamp, such as "A Physiotherapy Device" designed by Yu Jianhong on May 15, 2020. However, this reflective cover is small in size and generally adopts an open design, which causes the light to diverge and does not take into account the need to concentrate the light. Therefore, a Fresnel lens structure (focusing structure) is designed in this scheme, and the increase in the reflective design structure makes it cumbersome. In view of this, this invention is specially applied for. Utility Model Content
[0003] In order to solve the above-mentioned problems in the prior art, the utility model provides a reflective inner cover of an infrared therapeutic device, which can improve the above-mentioned deficiencies.
[0004] The utility model relates to a reflective inner cover of an infrared therapy instrument, which is used on a lamp head of an infrared therapy instrument, and comprises an inner cover body which is wide at the bottom and narrow at the top, wherein the inner cover body has a cut arc-shaped concave surface for installing an infrared lamp, the upper end of the inner cover body is an end portion, and the inner cover body is sequentially provided with a cylinder portion, a first curved surface portion, a parabolic surface portion and a second curved surface portion from the end portion to a direction away from the end portion, wherein the height of the cylinder portion is smaller than that of the first curved surface portion, the height of the first curved surface portion is smaller than that of the parabolic surface portion, the height of the second curved surface portion is smaller than that of the cylinder portion, and an edge is provided on the opening surface of the inner cover body, and three notches are provided on the edge.
[0005] Furthermore, the inner cover body includes an inner concave surface covered with a nano-coating coating.
[0006] Furthermore, a through hole is arranged in the middle of the end, and three mounting holes are arranged on the end, and the mounting holes are arranged around the outside of the through hole.
[0007] The utility model is cleverly designed, with an inner cover body which is provided with a cylindrical portion, a first curved portion, a parabolic portion and a second curved portion in sequence from the end portion to a direction away from the end portion. Due to the design of the parabola, it can be used to generate concentrated heat energy, and there is no need to separately provide a focusing structure on the lamp head.

[0012] In order to make the purpose, technical solution and advantages of the utility model more clear, the utility model is further described in detail below in conjunction with the accompanying drawings and embodiments. It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.
[0013] like Figure 1-3 As shown, the utility model relates to a reflective inner cover of an infrared therapy instrument, which is used on the lamp head of an infrared therapy instrument, including an inner cover body 1 that is wider at the bottom and narrower at the top. The inner cover body has a cut-arc concave surface for installing an infrared lamp, and the upper end of the inner cover body is an end 3. The inner cover body is sequentially provided with a barrel 5, a first curved surface 6, a parabolic surface 7 and a second curved surface 8 from the end to a direction away from the end. Since the parabolic portion is designed to generate parallel light here, the height of the barrel is smaller than the first curved surface, the height of the first curved surface is smaller than the parabolic surface, and the height of the second curved surface is smaller than the barrel. The opening surface of the inner cover body is provided with an edge, and three notches 21 are provided along the edge. The purpose of the notch is to clamp the inner cover body.
[0014] As a technical improvement, the inner cover body includes an inner concave surface covered with a nano-coating coating 102 .
[0015] Furthermore, a through hole 4 is arranged in the middle of the end, and three mounting holes 9 are arranged on the end, and the mounting holes are arranged around the outside of the through hole.
[0016] Furthermore, the reflection angle of the light source reflected by the second curved surface portion is less than 78°, where the product is non-parallel light and converges the light.
