This heating evaporation device is for evaporating and evaporating insecticides, bactericides, acaricides, repellents, pharmaceuticals, fragrances, cosmetics, etc. into the room for insecticide, deodorization and the like. There are various methods of vaporization and evaporation here, but as a method suitable for maintaining the effect of evaporation for a long period of time, a liquid to be evaporated, that is, an insecticide or the like is stored in a container and the liquid is evaporated. There is a structure in which the immersed liquid core is pulled out from the neck of the container and the liquid core is heated by an appropriate heating means to evaporate the absorbed liquid appropriately. Is equipped with an indicator light.

The above-mentioned heating evaporation device is widely used in general households and is often used on the floor or the like in addition to being small in size. Therefore, an indicator lamp is provided on the surface of the container and electricity is being supplied. It is configured so that the location can be easily confirmed. FIG. 8 is a block diagram showing a structural example of a conventional heating evaporation device, in which the main body is composed of the upper and lower parts 3 and 2 of the body, and the liquid container 1 having the liquid absorption core 11 is opened from the bottom side. It can be worn. The upper body 3 can be attached to the upper end of the lower body 2 by fitting or bonding.

[0005]

[Problems to be solved by the device]

 The translucent member 20 is for visually recognizing the faint light emitted from the light source 13 such as a neon lamp outside the body, and has a rod-shaped translucent portion 20a that transmits light while reducing the attenuation of the light and the outside of the body. It is composed of a radiating portion 20b for radiating light, a flange-shaped fixing portion 20c, and the like. In the light transmitting member 20 having the above-described configuration, the tip of the light transmitting portion 20a is extended to the vicinity of the light source 13, the light is collected by the tip, and the light emitting portion 20b provided at the other end emits light. Even if the light is weak, there is an advantage that it can be displayed brightly. However, in addition to requiring the rod-shaped light-transmitting portion 20a, the shape of the light-transmitting portion 20a must be changed according to the position of the light source 13, which is not compatible. In addition, there is a problem in that it is easily broken during installation, and workability is not good. Further, although the window 120 for confirming the residual liquid amount is provided, since the light source 13 is located above the liquid container 1, the light amount tends to be insufficient. As a substitute for the translucent member 20 having the above-described structure, a light receiving member that is a simple plate-shaped translucent plate is provided, but it has neither a light condensing function nor a translucent function and must be installed in the vicinity of the light source. It is accompanied by design restrictions such as not becoming. The present invention has been made in view of the above problems, and an object thereof is to provide a light receiving member that has a simple structure and is excellent in light collecting property and light transmitting property.

[0006]

Means for Solving the Problems The above-mentioned object of the present invention is to provide a light-receiving member configured to receive light emitted from a light source provided inside a body and visually transmit it outside the body. A projection is formed on one side surface of a plate-shaped body formed by a member, and the projection located on the opposite side of the light source is provided so as to be exposed on the surface of the body, and the light emitted from the light source is emitted. Is achieved by a light receiving member configured to receive light by the plate-shaped body having a surface larger than the cross section of the projection and transmit the light to the projection.

[0007]

[Action]

 According to the above configuration, the light emitted from the light source can be received by the plate-shaped body over a wide range, and the light can be condensed and transmitted to the protrusion. Therefore, even if the positions of the light source and the light receiving member are far apart, it is possible to brightly display the protrusion exposed to the outside of the body, and it is not always necessary to bring the position of the light display portion and the light source close to each other. In addition, the degree of freedom is increased, and since the structure is simpler than that of the conventional translucent member, damage is reduced and manufacturing cost can be reduced.

【Example】

 Hereinafter, a first embodiment of the present invention will be described with reference to FIGS. 1 is a perspective view showing a structure of a light receiving member 100 to which the present invention is applied, FIG. 2 is a cross-sectional view, and FIG. 3 is a sectional view showing an attached state. The light receiving member 100 is composed of a plate-shaped light receiving portion 101 and a columnar display portion 102 provided at the center of one side surface of the light receiving portion 101. The light-receiving unit 101 and the display unit 102 may be made of any material that is transparent to light, such as plastic, glass, and optical fiber. The light receiving unit 101 receives the light that illuminates the lower surface and collects the light on the display unit 102 provided on the upper surface. By widening the area of the light receiving unit 101, the light diffused in a wide range can be received. The display unit 102 becomes brighter in response to the received light, and the tip of the display unit 102 can be attached to the outside of the body so that the display unit 102 can function as the display unit.

As shown in FIG. 3, the mounting of the light receiving member 100 is performed by fitting the light receiving portion 101 into the step portion 112 formed on the inner frame 111 of the body 110 and displaying it in the insertion hole 114 provided in the outer frame 113. The part 102 is inserted and fixed. Then, the opening 115 that opens inside the step 112 is closed by the light receiving unit 101, and the light emitted from the light source 116 provided below the opening 115 illuminates the light receiving unit 101. The emitted light seems to be condensed by the light receiving unit 101, the display unit 102 becomes bright and shining, and the light source 116 is turned on. In other words, the light receiving unit member 100 is attached. You can see that the equipment is energized.

As described above, the light receiving member 100 can display light without using a rod-shaped member unlike the conventional structure. In addition, since the display portion 102 has a projecting shape, it can be used as a knob when mounting as shown in FIG. 3, and the workability is improved together with the fact that there is no risk of damage due to the rod-shaped member.

Next, the shape of the light receiving unit 101 will be described with reference to FIGS. 4 to 6. That is, the shape of the light receiving unit 101 is not limited to the flat plate shape as described in the first embodiment, and may be formed in an arcuate convex shape as shown in FIG. 4 or as an arcuate shape as shown in FIG. It may be formed in a concave shape. Further, as shown in FIG. 6, the lower surface on which light is incident may be formed in a flat plate shape and the upper surface may be formed in an arc shape. Further, the lower surface of the light receiving unit 101 may be formed in a corrugated shape, a fine conical shape, a triangular shape, a square shape, or the like. With these shapes, the light receiving area can be enlarged and the display on the display unit 102 can be made brighter.

Next, the application of the light receiving member 100 to a heating evaporation device will be described as an application example. As shown in FIG. 7, the light receiving member 100 according to the present invention is attached to the hole on the top surface of the body. In FIG. 7, the same components as those in FIG. 8 are designated by the same reference numerals and redundant description will be omitted. In this case, when the upper part 3 of the body is one, the upper surface of the light receiving part 101 may be used to attach the same by adhesion or the like, as shown in FIG. A structure may be adopted. In this case, even if the light receiving unit 101 and the light source 13 are widely separated as shown in the figure, the entire light receiving unit 101 is configured so as to face the light source 13, and a large amount of light can be received. The received light is collected by the display unit 102, and the display unit 102 becomes bright and shining, and it is possible to sufficiently visually recognize whether or not the power is being supplied. As the light source 13, a neon lamp or the like can be used as in the conventional light source. In this neon lamp, both end portions are formed in a tapered shape as shown in FIG. The lamp can be mounted horizontally, and as shown in FIG. 7, it is not necessary to hold the side surface of the light source 13 by the light source fixing portion 14, and the light source holding structure may be arbitrary. As described above, according to the present invention, for example, when the elongated light source 13 is arranged in a horizontal direction at a position away from the light receiving member 100, even if the light source 13 has the same brightness as the conventional light source, While 102 can be made sufficiently bright, the irradiation width of the liquid container 1 can be widened, so that the liquid container 1 can be illuminated brighter than before, and when confirming the residual liquid amount from the outside of the body (window 120). The confirmation becomes easy. Further, since the light receiving member 100 has a simple structure, it is easy to assemble the heating evaporation device, and the work efficiency can be improved.
