Abstract

A first chamber is configured to generate smoke from combustion of a combustible material within the first chamber. A second chamber is configured to house an electronic device. The first chamber and the second chamber are fluidly connected. The apparatus further includes an air pump configured to move the smoke generated in the first chamber into the second chamber. While the air pump is in operation, the electronic device in the second chamber is exposed to the smoke generated in the first chamber. The second chamber is further configured with an exhaust such that the smoke generated in the first chamber moves through the second chamber and out of the second chamber via the exhaust.

Claims (28)

1. An apparatus comprising:

a first chamber configured to generate smoke from combustion of a combustible material within the first chamber;

a second chamber configured to house an electronic device, wherein the first chamber and the second chamber are fluidly connected; and

an air pump configured to move the smoke generated in the first chamber into the second chamber, wherein, while the air pump is in operation:

the electronic device in the second chamber is exposed to the smoke generated in the first chamber, and

the second chamber is further configured with an exhaust such that the smoke generated in the first chamber moves through the second chamber and out of the second chamber via the exhaust.

2. The apparatus of claim 1 , wherein the first chamber comprises a pellet smoker configured to combust wood pellets.

3. The apparatus of claim 1 , wherein at least one of oak or pine wood is ignited in the first chamber to generate smoke.

4. The apparatus of claim 1 , wherein the electronic device is configured to be removable from the second chamber.

5. The apparatus of claim 1 , wherein the electronic device is a first electronic device, and further wherein the second chamber is further configured to house a second electronic device.

6. The apparatus of claim 1 , wherein the second chamber comprises at least one temperature sensor.

7. The apparatus of claim 1 , wherein the second chamber comprises at least one humidity sensor.

8. The apparatus of claim 1 , wherein the second chamber further comprises at least one sensor configured to measure at least one of particle size or a particle count in the smoke that moves through the second chamber.

9. The apparatus of claim 1 , further comprising a particle analyzer fluidly connected to the second chamber and configured to determine a type of particle in the smoke that moves through the second chamber.

10. The apparatus of claim 1 , wherein the second chamber further comprises a light emitter and a light receiver configured to measure obscuration density of the smoke that moves through the second chamber.

11. The apparatus of claim 1 , further comprising a sensor configured to detect an electrical load on the electrical device during exposure of the electrical device to the smoke generated in the first chamber.

12. The apparatus of claim 1 , further comprising a sensor configured to detect leakage of current through the electrical device during exposure of the electrical device to the smoke generated in the first chamber.

13. A method for exposing an electronic device to smoke to test the electronic device comprising:

placing combustible material into a first chamber;

placing the electronic device into a second chamber, wherein the first chamber and the second chamber are fluidly connected;

igniting the combustible material in the first chamber to generate smoke from the combustible material;

turning on an air pump to move the smoke from the first chamber to the second chamber; and

collecting data from at least one sensor in the second chamber while the air pump is on, wherein the air pump is on for at least a predetermined amount of time for the test.

14. The method of claim 13 , wherein the electronic device is powered on while the air pump is on.

15. The method of claim 13 , further comprising measuring performance of the electronic device while the air pump is on.

16. The method of claim 13 , wherein the electronic device is an optical electronic device.

17. The method of claim 13 , further comprising measuring the at least one characteristic of the electronic device while the air pump is turned on during the test or after the air pump is shut off after the test.

18. The method of claim 17 , further comprising measuring at least one characteristic of the electronic device before the air pump is turned on for the test.
