Detailed Description

Reference will now be made in detail to embodiments of the present invention, examples of which are illustrated in the accompanying drawings, wherein like reference numerals refer to the same or similar elements or elements having the same or similar function throughout. The embodiments described below with reference to the drawings are exemplary and intended to be used for explaining the present invention, and should not be construed as limiting the present invention.

As shown in fig. 1 and fig. 2, a light-emitting structure of a heating plate according to an embodiment of the present invention includes a lamp panel 1, a circuit board 2, a light guide column 3, a light guide ring 4, and a light-tight external member 5; the lamp panel 1 is provided with a lamp bead 11; the circuit board 2 is electrically connected with the lamp panel 1 and supplies power to the lamp beads 11 on the lamp panel 1; a groove 31 is formed in the light guide column 3, and the notch of the groove 31 is a lamp bead 11; the light guide ring 4 is arranged at the edge of the shell 6 of the heating plate, and an accommodating groove 41 for accommodating the light guide column 3 and the lamp bead 11 is formed in the light guide ring 4; the light-tight external member 5 is sleeved on the lamp panel 1 and the outer periphery of the light guide post 3 to drive the lamp beads 11 to emit light to the two sides of the light-tight external member 5 and emit the light into the light guide ring 4.

At comparatively dim corner or when night, circuit board 2 is the lamp pearl 11 power supplies on the lamp plate 1, make lamp pearl 11 luminous, the light that lamp pearl 11 sent leads the light through leaded light post 3, because

lamp plate

1 and 3 outer peripheral edges of leaded light post set up light-tight external member 5, make the light after 3 leaded lights of leaded light post can not see through light-tight external member 5, and can only launch to light guide ring 4 along 5 lateral walls of light-tight external member, and light guide ring 4 further leads light, thereby improve the light efficiency. Therefore, the utility model discloses it makes the heating plate have the illumination instruction function for when comparatively dim corner or using at night, conveniently place electric kettle on the heating plate, and the light efficiency is high.

In some examples, the groove 31 formed in the light guide post 3 is an arc-shaped groove, a first step 311 is formed on one side wall of the arc-shaped groove, the first step 311 is abutted against one side of the lamp bead 11, a second step 312 is formed on the other side wall of the arc-shaped groove, and the second step 312 is abutted against the other side of the lamp bead 11, so that the light guide post 3 can be covered on the lamp bead 11, the light guide post is prevented from shaking, and the light-tight sleeve 5 is convenient to be arranged on the outer peripheries of the lamp panel 1 and the light guide post 3. Simultaneously, the notch of arc recess is lamp pearl 11 for in the light that sends of lamp pearl 11 refracts to leaded light post 3 through the arc recess, the refraction of arc recess is effectual, refracts to the leaded light circle 4 again, thereby improves the light efficiency.

In some examples, the light guide ring 4 is provided with sawtooth-shaped corrugations 42, and when the light is refracted into the light guide ring 4, the sawtooth-shaped corrugations 42 further refract and reflect the light, so that the light efficiency is further improved.

In some examples, the number of the accommodating grooves 41 formed on the light guide ring 4 is at least four, and the plurality of accommodating grooves 41 are symmetrically distributed. In this example, the number that forms holding tank 41 on the light guide ring 4 is four, and four holding tank 41 evenly distributed set up on light guide ring 4, set up four lamp plates 1 in four holding tank 41 respectively, can establish ties between four lamp plates 1, and lamp pearl 11 on four lamp plates 1 has improved the luminance of whole light guide ring 4.

In some examples, the light-tight sleeve 5 is a light-tight heat-shrinkable tube, which is sleeved on the lamp panel 1 and the outer periphery of the light guide post 3 during assembly, and then heated to shrink the light-tight heat-shrinkable tube, so as to fix the light guide post 3 on the lamp bead 11, thereby completing the assembly.
