Detailed Description

Example 1

The applicant provides a waterproof camera based on the technical problem that after an existing camera is placed under water for a period of time, the sealing performance of the existing camera is gradually reduced due to water pressure, water mist is generated inside the camera due to the fact that the temperature difference between the water temperature and the inside of a camera body affects shooting effect, and the waterproof camera is shown in figure 1. The device comprises a shell 1, wherein a front end cover 101 and a rear end cover 102 are respectively connected to two end faces of the shell 1 in a sealing mode. In the present embodiment, as shown in fig. 2, the front cover 101 is hermetically attached to the housing 1 by: the front end cover 101 is fixed at the end face of the shell 1, a rubber sealing ring 103 is arranged between the front end cover 101 and the end face of the shell 1, and the two side faces of the rubber sealing ring 103 are respectively matched with the front end cover 101 and the end face of the shell 1 in a concave-convex mode to realize sealing connection. The inner wall of the rubber sealing ring 103 is provided with an annular clamping groove 104, and the annular clamping groove 104 is used for installing and fixing the lens 2.

The rear end cap 102 is sealingly connected to the housing 1 by: the rear end cap 102, as shown, has a connecting portion and a stopper portion, and the connecting portion is a sealing threaded pipe and is connected to the end face of the housing 1 through the sealing threaded pipe. Meanwhile, in order to increase the sealing effect, a cross-section sealing O-shaped ring 105 is fixed between the stop part and the end face of the shell 1 for further sealing.

The waterproof camera of this embodiment still includes: the camera module 3 is fixed in the shell 1 and is adjacent to the lens 2; wherein the camera module 3 adopts the camera module 3 under water among the prior art can, and the unnecessary repeated description is here done. When the camera module 3 is fixed, the inner wall of the housing 1 is provided with an annular boss 106, and the camera module 3 is fixed on the annular boss 106 through screws or other forms.

Further comprising: the drying component 4 of setting between camera module 3 and rear end cap 102 still possesses the heating function when drying component 4 has drying function. As shown in fig. 4, the drying assembly 4 includes: one terminal surface is the cavity 401 of open structure, and open structure department detachable is provided with backing plate 402, adopts 3M cushion 404 to accomplish the fixed of backing plate 402 constantly in the installation. The interior of the cavity 401 is provided with a desiccant 405, the desiccant 405 serving to normally adsorb moisture inside the housing 1. In this embodiment, the cavity 401 is also adhered to the inner wall of the housing 1 by the 3M rubber pad 404.

The drying assembly 4 further comprises: the ceramic heating sheet 406 adhered to the outside of the cavity 401 through the 3M rubber mat 404 is arranged opposite to the camera module 3. The ceramic heating sheet 406 is used for heating the inside of the housing 1 when the moisture inside the housing 1 is too large (when water mist appears on the lens 2), so that the ceramic heating sheet 406 is connected with a power supply through a wire, the power supply is fixed outside the housing 1, and the power supply adopts 5V direct-current voltage. In this embodiment, the temperature of the ceramic heater chip 406 after being energized is 50 to 52 ℃.

Therefore, in order to ensure that the device inside the housing 1 can normally perform its own function without being affected by temperature under the environment of 50 to 52 ℃, in the embodiment, the cavity 401 and the backing plate 402 are made of nylon, and the nylon material has heat resistance at 50 to 52 ℃. The desiccant used in the embodiment is a lens moisture-proof defogging desiccant which is already popular in the prior art or the existing market.

Meanwhile, threading grooves 403 are correspondingly formed in the cavity 401 and the backing plate 402, the threading grooves 403 are used for providing space for the circuits of the camera module 3 and the wires of the ceramic heating sheet 406, and a glan head 407 is mounted on the rear end cover 102.
