Abstract

An image capturing device with waterproofing, comprising a main body, a first sensing unit, and a pressure control module. The main body has a containing space for containing an electronic component set. The first sensing unit is disposed at the outside of the main body and used for sensing the pressure where the main body is located to obtain a first pressure value. The pressure control module is disposed in the containing space of the main body and electrically connected to the first sensing unit. By using a second pressure sensing unit to sense the pressure of the containing space, the pressure control module obtains a second pressure value and compares the relative deviation of the first pressure value and the second pressure value through a processing unit to adjust the inner pressure of the image capturing devices.

Claims

1. An image capturing device with waterproofing, comprising:

a main body comprising a containing space for containing an electronic component set;

a first sensing unit set outside the main body for sensing a pressure the main body located and obtaining a first pressure value; and

a pressure control module set inside the containing space of the main body and electronically connected to the first sensing unit, comprising;

a second sensing unit sensing the pressure of the containing space and obtaining a second pressure value;

a processing unit receiving the first pressure value and the second pressure value, comparing relative deviation between the first pressure value and the second pressure value, and determining if deviation between the first pressure value and the second pressure value is larger than a preset value, then providing a pressurization adjustment signal, a depressurization adjustment signal, a pressurization stop signal or a depressurization stop signal; and

a pressurization unit receiving the pressurization adjustment signal from the processing unit and releasing gas to the containing space until the second pressure value increases to be equal to the first pressure value.

2. The image capturing device with waterproofing as recited in claim 1, wherein the processing unit provides the pressurization adjustment signal to the pressurization unit while the second pressure value becomes smaller than the first pressure value and the deviation between the first pressure value and the second pressure value is larger than the preset value, and the processing unit provides the pressurization stop signal to the pressurization unit while the second pressure value increases until the deviation between the first pressure value and the second pressure value becomes smaller than the preset value.

3. The image capturing device with waterproofing as recited in claim 1, wherein the portable device further comprises a depressurization unit which is disposed on the main body and connected interior and exterior of the main body for reducing the pressure of the containing space.

4. The image capturing device with waterproofing as recited in claim 3, wherein the second pressure value is larger than the first pressure value and the deviation between the first pressure value and the second pressure value is larger than the preset value, the processing unit provides the depressurization adjustment signal to the depressurization unit.

5. The image capturing device with waterproofing as recited in claim 4, wherein the depressurization unit is electronically connected to the processing unit for receiving the depressurization adjustment signal from the processing unit, and automatically dismantling the gas in the containing space until the second pressure value reduces to be equal to the first pressure value.

6. The image capturing device with waterproofing as recited in claim 5, wherein the second pressure value reduces until the deviation of the second pressure value and the first pressure value becomes smaller than the preset value, the processing unit provides the depressurization stop signal to the depressurization unit.

7. The image capturing device with waterproofing as recited in claim 3, wherein further comprising a gas inlet unit located on the main body and connecting interior and exterior space of the main body for providing a manual pressurization which is completed by injecting gas manually into the containing space.

8. The image capturing device with waterproofing as recited in claim 7, wherein the gas inlet unit comprises an inlet hole, which is sealed when it is not used.

9. The image capturing device with waterproofing as recited in claim 3, wherein the depressurization unit provides a manual depressurization which is completed by manually opening the depressurization unit for dismantling the gas inside the containing space.

10. The image capturing device with waterproofing as recited in claim 4, wherein the depressurization unit comprises a depressurization gate.

11. The image capturing device with waterproofing as recited in claim 2, wherein the pressurization unit comprises a small compressed gas steel bottle.
