Abstract

Devices, systems, and methods for an aspirating smoke detector device are described herein. In some examples, one or more embodiments include an aspirating smoke detector device comprising a printed circuit board (PCB), a manifold including a first flow channel and a second flow channel, a blower housing configured to receive a blower, a first sensor head housing connected to the blower housing via the first flow channel, wherein the first sensor head housing is configured to receive a first sensor head, and a second sensor head housing connected to the blower housing via the second flow channel, wherein the second sensor head housing is configured to receive a second sensor head, and a gasket configured to fluidically seal the manifold to the PCB.

First claim

What is claimed:

1. An aspirating smoke detector device, comprising:
a manifold, including:
a flow channel;
a blower housing configured to receive a blower; and
a sensor head housing connected to the blower housing via the flow channel, wherein the sensor head housing is configured to receive a sensor head; and

a gasket configured to fluidically seal the manifold.

2. The aspirating smoke detector device of claim 1 , wherein the aspirating smoke detector device further includes a pair of ultrasonic sensors in the flow channel, wherein the pair of ultrasonic sensors are configured to measure a gas flow rate of a gas through the aspirating smoke detector device.

3. The aspirating smoke detector device of claim 1 , wherein the aspirating smoke detector device further includes a printed circuit board (PCB).

4. The aspirating smoke detector device of claim 3 , wherein the gasket is configured to fluidically seal the manifold to the PCB.

5. The aspirating smoke detector device of claim 1 , wherein the flow channel has a constant cross-sectional dimension through a length of the flow channel.

6. The aspirating smoke detector device of claim 1 , wherein the blower housing is configured to receive a blower housing cover configured to fluidically seal the blower housing.

7. The aspirating smoke detector device of claim 1 , wherein the sensor head housing is configured to receive a sensor head housing cover configured to fluidically seal the sensor head housing.

8. The aspirating smoke detector device of claim 1 , wherein the blower housing is shaped such that the blower housing is configured to receive the blower in a single orientation.

9. The aspirating smoke detector device of claim 1 , wherein the sensor head housing is shaped such that the sensor head housing is configured to receive the sensor head in a single orientation.

10. An aspirating smoke detector device, comprising:
a manifold, including:
a flow channel;
a blower housing configured to receive a blower; and
a sensor head housing connected to the blower housing via the flow channel, wherein the sensor head housing is configured to receive a sensor head;

a pair of ultrasonic sensors exposed in the flow channel, wherein the pair of ultrasonic sensors are configured to measure a gas flow rate of a gas through the aspirating smoke detector device; and
a gasket configured to fluidically seal the manifold.

11. The aspirating smoke detector device of claim 10 , wherein the aspirating smoke detector device further includes a printed circuit board (PCB) configured to control a speed of the blower.

12. The aspirating smoke detector device of claim 10 , wherein the blower is configured to move the gas through the aspirating smoke detector device.

13. The aspirating smoke detector device of claim 10 , wherein the sensor head is configured to measure smoke particles in the gas.

14. An aspirating smoke detector device, comprising:
a printed circuit board (PCB) including a pair of ultrasonic sensors;

a manifold, including:
a flow channel;
a blower housing configured to receive a blower, wherein the blower is configured to move gas through the aspirating smoke detector device; and
a sensor head housing connected to the blower housing via the flow channel, wherein the sensor head housing is configured to receive a sensor head, wherein the sensor head is configured to measure smoke particles in the gas; and
a gasket configured to fluidically seal the manifold to the PCB;

wherein the pair of ultrasonic sensors are exposed in the flow channel and are configured to measure a gas flow rate of the gas through the aspirating smoke detector device.

15. The aspirating smoke detector device of claim 14 , wherein the aspirating smoke detector device further includes a housing to house the PCB and the manifold, wherein the housing includes a housing inlet and a housing outlet.

16. The aspirating smoke detector device of claim 15 , wherein the sensor head housing includes a sensor head housing inlet that is coaxial with the housing inlet.

17. The aspirating smoke detector device of claim 16 , wherein the blower is configured to move the gas into the sensor head housing to the sensor head via the housing inlet and the sensor head housing inlet.

18. The aspirating smoke detector device of claim 15 , wherein the aspirating smoke detector device includes a mesh screen outlet adapter connected to the housing outlet.

19. The aspirating smoke detector device of claim 18 , wherein the gas is exhausted from the aspirating smoke detector device via the mesh screen outlet adapter.

20. The aspirating smoke detector device of claim 19 , wherein the aspirating smoke detector device includes an exhaust pipe connected to the mesh screen outlet adapter such that the gas is exhausted via the mesh screen outlet adapter and the exhaust pipe.
