Problems solved by technology

[0010] However, in traditional fire detectors, for different types of fire detectors, not only the detection parts of the fire detectors need to be designed and produced separately, but also the various parts combined with the housing must be designed and produced separately
Therefore, undoubtedly increased the production cost of fire detectors

[0094] An embodiment of the present invention will be described below with reference to the drawings.

[0095] Figure 1A Is a plan view showing the appearance of a fire detector 10 as an embodiment of the present invention, Figure 1B Is its side view. Figure 2A It is a side view of the disassembled state of the various parts of the housing constituting the fire detector 10, Figure 2B It is a plan view of the shell. image 3 Is along Figure 1A A cross-sectional view of the fire detector 10 taken along the line A-A shown.

[0096] The fire detector 10 is a light scattering type smoke detector. When installing the fire detector 10 on the ceiling of a building, Figure 1B The upper side shown—that is, the top of the fire detector—is facing downward.

[0097] Such as Figure 1A to Figure 3 As shown, the exterior of the fire detector 10 is composed of a cover 11, a light guide member 20, a housing 30, and a base 31.

[0098] Such as image 3 As shown, the circuit board 32 is fixed t...

Abstract

A fire detector which can be observed an operating state thereof from every direction and decrease a cost thereof as possible. The fire detector (10) comprises: the circuit board (32) in which the circuit for detecting a fire is formed; the LED (35) which is surface-mounted on the circuit board (32); and the indication lamp for indicating the fire detector being under detection by emitting the light emitted from the LED (35), wherein the indication lamp comprises the light guide member (20) for introducing the light emitted from the LED (35) to the indication lamp with a ring shape, the light guide member (20) comprises the light incident parts (21) and (21) and the ring member (22), notches (23) and (23) are formed in the vicinity of the light incident parts (21) and (21) of the ring member (22), and a plurality of small grooves (24), and (24) . . . are formed in the bottom surface (22d) of the ring member (22).

Description

Technical field [0001] The invention relates to a fire detector with indicator lights. Background technique [0002] According to traditional fire detectors, most of the indicator lights used to indicate that the fire detector is in the detection state are set at a position on the surface of the fire detector, for example, like the Japanese Utility Model Patent Application Bulletin (examined) SHO 61- No. 1511 and Japanese Utility Model Patent Application Publication (Unexamined) Sho 58-189954. [0003] Figure 14A with 14B An example of this type of conventional fire detector is shown. Figure 14A It is a plan view of this traditional fire detector. Figure 14B It is a side view of this traditional fire detector. in Figure 14A with 14B Among them, reference number 1 represents a fire detector used to detect fire, and reference number 2 represents an indicator light that indicates that the fire detector is in a detection state by emitting light. [0004] Such as Figure 14A with...
