Abstract
The utility model relates to a kind of dust-proof shell structures of smoke detector, are composed of sequentially connected upper casing, middle part mounting disc and lower casing, and up-narrow and down-wide taper is made in upper casing, are formed with a circle smoke intaking hole the ring wall of upper casing is radially uniform.The innovative point of the utility model is that by smoke intaking hole system, on the top of shell, labyrinth is corresponding towards upper.Smoke intaking hole is close apart from wall top, and dust is not easy to fall into smoke intaking hole.
Description
Technical field
The utility model belongs to cigarette sense field, is related to shell, the dust-proof shell structure of especially a kind of smoke detector.
Background technique
Existing smoke detector, smoke intaking hole are to make in the lower part of shell, corresponding labyrinth also under, this design
The disadvantage is that dust is easy to enter in detector housing from smoke intaking hole, dust stratification influences the Normal Alarm of detector too much.
Utility model content
The purpose of the utility model is to overcome in place of the deficiencies in the prior art, a kind of dustproof shell of smoke detector is provided
Body structure avoids dust and enters inside detector.
The utility model technical scheme applied to solve the technical problem is:
A kind of dust-proof shell structure of smoke detector, combined by sequentially connected upper casing, middle part mounting disc and lower casing and
At up-narrow and down-wide taper is made in upper casing, is formed with a circle smoke intaking hole the ring wall of upper casing is radially uniform.
Moreover, installing labyrinth towards upper casing in the upper surface of middle part mounting disc, pacify below the mounting disc of middle part towards lower casing
Device, circuit board.
Moreover, installing indicator light towards user in the bottom surface of lower casing.
It is switched moreover, being installed in the bottom surface of lower casing towards user.
Moreover, installing battery in middle part mounting disc.
Moreover, installing buzzer in middle part mounting disc.
Moreover, the top surface in upper casing is formed with bolt mounting holes.
Moreover, upper casing and middle part mounting disc, middle part mounting disc by buckle or screw thread or is bolted with lower casing.
The advantages and positive effects of the utility model are as follows:
The innovative point of the utility model is that by smoke intaking hole system, on the top of shell, labyrinth is corresponding towards upper.Smoke intaking hole away from
Close from wall top, dust is not easy to fall into smoke intaking hole.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
The utility model is described in further detail with reference to the accompanying drawing and by specific embodiment, and following embodiment is only retouched
The property stated, it is not restrictive, protection scope of this utility model cannot be limited by this.
A kind of dust-proof shell structure of smoke detector, is combined by sequentially connected upper casing 1, middle part mounting disc 2 and lower casing 3
It forms, up-narrow and down-wide taper is made in upper casing, a circle smoke intaking hole 4 is formed with the ring wall of upper casing is radially uniform, in middle part mounting disc
The upper surface of towards upper casing install labyrinth 5, towards lower casing mounting circuit boards 6 below the mounting disc of middle part, in the bottom surface court of lower casing
Indicator light 7 is installed to user.
Bolt mounting holes are formed in the top surface of upper casing.At middle part, battery, buzzer are installed in mounting disc.In the bottom surface court of lower casing
Indicator light, switch are installed to user.Upper casing and middle part mounting disc, middle part mounting disc and lower casing pass through buckle or screw thread or bolt
Connection.
Smog enters in labyrinth from upper casing, after testing, will start buzzer and luminous alarm beyond detection threshold.
Above-described is only preferred embodiments of the present invention, it is noted that for the ordinary skill of this field
For personnel, under the premise of not departing from utility model design, various modifications and improvements can be made, these belong to this reality
With novel protection scope.
