Abstract
Embodiments disclosed herein provide a detector unit and sensor chamber with matter retention member and method for making the same. In one embodiment, a smoke chamber can include a detection circuitry member having a surface, a particle trapping member mounted to the surface, and a chamber coupled to the detection circuitry member. The chamber can include a planar member, and several baffles extending away from the planar member in the direction towards the detection circuitry member and disposed around a periphery of the planar member, wherein a distal end of each baffle interfaces with the particle trapping member.
Claims24
A smoke chamber comprising:
- a detection circuitry member having a surface;
- a particle trapping member mounted to the surface;
- and
- a chamber coupled to the detection circuitry member, the chamber comprising:
- a planar member;
- and
- a plurality of baffles extending away from the planar member in the direction towards the detection circuitry member and disposed around a periphery of the planar member, wherein a distal end of each baffle interfaces with the particle trapping member.
A method for assembling a smoke chamber, comprising:
- aligning a particle retaining member with respect to a detection circuitry member of the smoke chamber, the particle retaining member comprising a release liner;
- securing the aligned particle retaining member to the detection circuitry member;
- removing the release liner from the particle retaining member;
- and
- coupling a chamber comprising a plurality of baffles to the detection circuitry member such that a distal end of each one of the baffles interface with the particle retaining member.
A hazard detection unit for detecting a presence of smoke, the unit comprising:
- a housing having an interior region and a plurality of openings through which air flows to access the interior region, the housing comprising:
- a back plate that is couplable to a mounting surface;
- a front casing coupled to the back plate to define the interior region of the housing;
- a circuit board coupled to the back plate;
- an alarm device mounted on the circuit board, the alarm device operative to sound an alarm in response to detection of the presence of smoke;
- and
- a smoke chamber secured to the circuit board, the smoke chamber comprising:
- a first surface;
- a particle trapping member mounted to the first surface;
- a second surface;
- and
- a plurality of baffles extending away from the second surface in a direction towards the first surface, wherein the plurality of baffles collectively form peripheral side walls of the smoke chamber, wherein a distal end of each baffle interfaces with the particle trapping member.
A hazard detection unit, comprising:
- a smoke detection sensor comprising a planer member that defines a first plane and a smoke detection circuitry that is sunken with respect to the planer member such that a portion of the smoke detection circuitry is co-planer with the first plane, wherein the smoke detection circuitry comprises a slot contained within a sunken portion of the smoke detection circuitry;
- at least one particle retention member disposed on the planer member and adjacent to the smoke detection circuitry;
- and
- at least a second particle retention member disposed over the slot.
